Technical Field

The invention relates to the field of inspection well water quality monitoring, in particular to an inspection well early warning management system for monitoring water quality.

Background

Inspection wells, which are ground access openings for underground pipelines, are typically covered by inspection well lids. In cities, all public water supplies, sewer pipes, telephone lines and optical fiber networks may be connected through underground passages under inspection wells. The inspection well of the sewage channel is an important channel leading to the sewage channel, and when a sewage sample in the sewage channel is collected, the sewage sample is often collected from the inspection well.

Regarding sewage canals, the zero-line sewage discharge project of municipal works is actively spreading everywhere. The zero-direct sewage drainage project is characterized in that sewage generated in production, life and operation activities is collected in a sewage interception and collection mode, and the sewage can be discharged to an external environment after being treated to reach standards, so that 'no water is drained in sunny days, and no sewage is drained in rainy days'. Sewage generated by production, life and operation activities is collected in a sewage interception and receiving pipe and unified manner, and is discharged to an external environment after being treated to reach the standard, so that urban sewage collection and rainwater and sewage distribution are realized.

The project of zero-straight sewage drainage has many problems in engineering practice, such as direct discharge into the sewage channel without interception or treatment, or poor effect of the sewage interception receiving pipe, which causes untreated sewage to directly escape into the sewage channel. The untreated sewage is directly discharged into the sewage canal, and for this reason, the sewage discharge point is usually inspected by manpower in a chemical inspection mode, and whether the sewage is directly discharged or not is determined according to the analysis of the inspected sewage components, and then the tracing is performed. However, the manual spot inspection method is lack of real-time performance and complex in underground pipe network, and after directly-discharged sewage is spot inspected, the sewage possibly spreads over the underground sewer, so that the source tracing point is difficult to confirm. Secondly, the sewage is directly discharged only because of leakage for a while, and the leakage is stopped during tracing, thereby increasing the difficulty of tracing. And thirdly, due to the complexity of sewage components, different organic matters in different sewage components can float or settle, the sewage in the upper layer, the middle layer and the lower layer at the same point is taken, the detection results are possibly inconsistent, comparative analysis is needed, and the workload and the working difficulty are increased. If a sensor is used to detect sewage, since the height of the sewer level is dynamically changed, if the sensor is exposed to the water surface, an erroneous detection result may be transmitted.

Specifically, the water quality sensor 1 can detect the quality of sewage in the sewage channel in real time, and the water quality sensor 1 has IP 68-level water resistance and can adapt to the severe environment under the sewage channel inspection well. The signal transmission device 2 is a wireless communication device, the water quality sensor 1 transmits the detected water quality data to the signal transmission device 2, and the signal transmission device 2 uploads the water quality data to the cloud service platform 6.

The signal transmission device 2 is arranged outside the inspection well, and the signal of the signal transmission device 2 needs to be ensured to be good. The number of the signal transmission devices 2 is set according to the density of the water quality sensors 1, and one signal transmission device 2 can simultaneously connect a plurality of water quality sensors 1.

The cloud service platform 6 is a cloud server with a communication function, and can realize functions of data transmission, analysis, storage and the like.

The mobile terminal device 7 is a mobile phone, a computer or other special communication devices of the user, and the user calls the information of the cloud service platform 6 by downloading a special APP on the mobile terminal device 7 and registering an account on the cloud service platform 6. The mobile terminal device 7 can be provided with a plurality of mobile terminal devices, signal communication is carried out between the mobile terminal device 7 and the cloud service platform 6, and the cloud service platform 6 sends the received water quality data to the mobile terminal device 7 in real time. Therefore, a user can know the water quality conditions of the sewage channels of all inspection well nodes in time through the mobile terminal device 7. When direct blowdown takes place, through the detection data of the water quality sensor 1 who transfers each inspection shaft node, the quality of water of inspection shaft that detects to some places worsens comparatively obviously, use these inspection shafts as the center, investigate pollution discharge factory around it, cut dirty admission pipe, find the source of directly arranging, guarantee going on of zero directly arranging project.

In order to detect the water quality of multiple layers in the sewer inspection well in real time, but because of different densities of the sewer inspection well and limited system cost, the following two installation modes of the water quality sensor 1 are provided, and the two installation modes are selected according to local conditions, wherein the first installation mode of the water quality sensor 1 is as shown in fig. 4 and 5:

in places with dense inspection wells or places with uncomplicated sewer pipe networks, only one water quality sensor 1 is arranged in one inspection well, but the height of the water quality sensors 1 in the adjacent inspection wells is different. Arranging a water quality sensor 1 in one inspection well close to the bottom of a sewage channel, and arranging the water quality sensor 1 in the inspection well adjacent to the inspection well in the middle of the sewage channel; and selecting one inspection well close to the two inspection wells, and arranging the water quality sensor 1 in the inspection well at a position close to the top of the sewage channel.

Specifically, a slotted hole is formed in the side wall of the inspection well, and the fixing arm 4a is fixed by clamping two ends of the fixing arm 4a into the slotted hole of the inspection well.

The attachment of the connecting section 4c can be achieved by suspending the mounting 4b from the fixing arm 4a by means of the connecting section 4 c.

The second mounting method of the water quality sensor 1 is as shown in fig. 6 and 7:

a plurality of water quality sensors 1 are arranged in the same inspection well, and the installation heights of the water quality sensors 1 in the same inspection well are different.

Specifically, in a place where the inspection wells are not dense or a place where an underground pipe network of a sewage channel is complex, one inspection well is provided with a plurality of water quality sensors 1 which are arranged up and down.

The water quality sensor 1 is economical in installation mode, but only suitable for places with dense inspection wells or places with uncomplicated underground pipe networks, so that the interference of detection results is small. Although the installation mode II of the water quality sensor 1 is not economical, the water quality detection result of the sewage channel below each inspection well is complete and clear, and the water quality sensor is suitable for places with complicated underground pipe networks of the sewage channels or non-dense inspection wells.

Two installation modes of the water quality sensor 1 are in the inspection well early warning management system, the inspection well early warning management system is supplemented with each other, the inspection well early warning management system is selected according to the concentration degree of the inspection well and the complexity degree of an underground pipe network of a sewage channel, different installation modes are selected at different positions, the inspection well early warning management system is most economical and practical and can meet the use requirements.

Further, in order to solve the technical problem of how to mount the water quality sensors 1 using the suspending and fixing structure 4 in a single inspection well in the second mounting method of the water quality sensors 1, as shown in fig. 10, 11, 14, and 15, the following preferable technical solutions are provided:

inspection shaft early warning management system is still including suspending fixed knot structure 4 in midair, a plurality of water quality sensor 1 in the same inspection shaft rely on suspending fixed knot structure 4 and become hanging in the inspection shaft of cluster, it includes fixed arm 4a to suspend fixed knot structure 4 in midair, installed part 4b and linkage segment 4c, fixed arm 4a fixed mounting is in the inspection shaft, installed part 4b has a plurality of, a plurality of installed part 4b relies on the linkage that linkage segment 4c becomes the cluster together, the one end of installed part 4b that links together in cluster is connected on fixed arm 4a, install on installed part 4b of water quality sensor 1 one-to-one.

Specifically, the two mounting modes of the water quality sensor 1 are the same in the selected hanging and fixing structure 4. In the first installation mode of the water quality sensor 1, only one water quality sensor 1 needs to be installed on each suspension fixing structure 4; in the second installation method of the water quality sensor 1, since a plurality of water quality sensors 1 need to be installed for each suspension fixing structure 4, a method of providing a plurality of installation pieces 4b by one suspension fixing structure 4 is adopted, and the installation pieces 4b are connected with the installation pieces 4b through the connecting sections 4 c.

The suspension fixing structure 4 has the following two implementation methods:

In the second embodiment, the connecting section 4c is a chain, the position of the installed water quality sensor 1 is not stable enough, when severe conditions such as centralized drainage to a sewage channel or leakage of an urban water supply system occur, large water flow is generated in the sewage channel, the connecting section 4c adopting the metal chain is impacted and shaken by the water flow, even collides with the wall of the sewage channel, and physical damage is easily caused to the water quality sensor 1; moreover, the installation piece 4b hung on the connection section 4c is easy to incline, so that the position of the water quality sensor 1 is inclined, the installation position of the water quality sensor 1 has strict requirements, and the normal use of the water quality sensor 1 is influenced by the inclination of the position.

In the first embodiment, since the connecting section 4c is a metal rod, the mounting part 4b is a metal platform, and the fixing arm 4a, the mounting part 4b and the connecting section 4c are all fixedly connected together. The position of the mounting member 4b is relatively fixed, and the mounting member 4b does not shake or tilt, thereby providing a good working environment for the water quality sensor 1.

In order to provide a stable working environment for the water quality sensor 1, the embodiment is a preferred embodiment of the suspending fixing structure 4.

Further, in order to solve the technical problem that when the water level in the sewage conduit drops, the water quality sensor 1 on the upper layer is exposed out of the water surface, so that not only an effective test result cannot be obtained, but also an erroneous test result is transmitted to the signal transmission device 2, so that the test result is mixed up, and the normal operation of the system is affected, as shown in fig. 2, 4, 5, 6 and 7, the following preferred technical solutions are provided:

The cloud service platform 6 classifies the water quality sensors 1 in the area where the liquid level meter 3 is located into a set, and the installation height and position information of each water quality sensor 1 can be recorded into the cloud service platform 6 in advance. The liquid level meter 3 uploads the water level information to the cloud service platform 6, the cloud service platform 6 compares the water level in each block with the installation height of the water quality sensor 1, and the water quality detection result of the water quality sensor 1 with the installation height higher than the current water level is shielded.

The cloud service platform 6 not only transmits the water quality data to the mobile terminal device 7, but also the cloud service platform 6 transmits the installation height and position information of the water quality sensors 1 and the water level data of the sewage channel of each parcel to the mobile terminal device 7, and simultaneously the cloud service platform 6 transmits the shielded information of the detection results of the water quality sensors 1 to the mobile terminal device 7, so that a user can completely know the changes of the water quality level and the like of the sewage channel from the mobile terminal device 7.

Further, in order to solve the technical problem of how to supply energy to the water quality sensor 1 and the signal transmission device 2, as shown in fig. 2, 4, 5, 6 and 7, the following preferred technical solutions are provided:

The energy sources of the water quality sensor 1, the signal transmission device 2 and the liquid level meter 3 are all provided by a storage battery 5. The power of the water quality sensor 1 and the signal transmission device 2 is low, and the electric quantity of the storage battery 5 can completely meet the requirement. In addition, in the inspection well early warning management system, the system needs to be regularly maintained: regular inspection is carried out to water quality sensor 1, signal transmission device 2 and liquid level appearance 3, guarantees that water quality sensor 1 does not have the damage, and water quality sensor 1's operational environment is normal, and water quality sensor 1's sensor probe normal operating, and signal transmission device 2 and liquid level appearance 3 normal operating are undamaged.

Further, in order to solve the technical problem of how to detect which water pollution the water quality sensor 1 can detect, the following preferred technical scheme is provided:

the water quality sensor 1 comprises a COD probe.

The water quality sensor 1 also comprises an ammonia nitrogen probe.

Specifically, COD, i.e. chemical oxygen demand, refers to the amount of oxidant consumed by oxidizing reducing substances in 1 liter of water sample, converted into milligrams of oxygen required after each liter of water sample is completely oxidized, expressed in mg and L, under a certain condition. It reflects the degree of contamination of the water by reducing substances.

The COD probe and the ammonia nitrogen probe are both provided with self-cleaning brushes, so that pollutants attached to the surface of the probe can be cleaned, and the maintenance period of the water quality sensor 1 is prolonged under the condition that the use of the probe is not influenced.

The working principle of the COD probe is as follows: many organic substances dissolved in water have an absorbing effect on ultraviolet light. Therefore, by measuring the degree of absorption of the organic substances by UV light with a wavelength of 254nm, the total amount of organic contaminants in water can be measured. The Y551-B sensor adopts two paths of light sources, one path of 254nm ultraviolet light and the other path of 365nm ultraviolet reference light, and can automatically eliminate the interference of suspended substances, thereby realizing more stable and reliable measurement values.

The ammonia nitrogen probe is an online ammonia nitrogen sensor, does not need a reagent, is green and pollution-free, and can be used for online real-time monitoring.
