(2) the sensor is easy to be dirty and damaged, and the maintenance cost is increased.

As shown in fig. 1, a bidirectional water quality measuring pipeline device comprises a pipeline main body 1 which is provided with a valve and controls water inlet and outlet through an electromagnet; the pipeline main body 1 is provided with a first water inlet 101, a second water inlet 102, a first water outlet 103, a second water outlet 104 and a cleaning assembly 11; the cleaning assembly 11 is arranged on the pipeline middle base 14, and is used for cleaning or brushing the measuring part of the sensor 2 for water quality monitoring under the action of water flow; the first water inlet 101 is provided with a first upper stop valve portion 131, the second water inlet 102 is provided with a second upper stop valve portion 132, the first water outlet 103 is provided with a first lower stop valve portion 133, and the second water outlet 104 is provided with a second lower stop valve portion 134; the first upper cut valve portion 131, the second upper cut valve portion 132, the first lower cut valve portion 133, and the second lower cut valve portion 134 are used to control the flow of water.

In this embodiment, the first water inlet 101 is disposed above the first water outlet 103, and the first valve control cavity 121 is spaced between the first water inlet 101 and the first water outlet 103; the second water inlet 102 is disposed above the second water outlet 104, and the second valve-controlled cavity 122 is spaced between the second water inlet 102 and the second water outlet 104. The first valve stem 1210 and the second valve stem 1220 may slide up and down.

In the present embodiment, the first upper cut valve portion 131, the second upper cut valve portion 132, the first lower cut valve portion 133, and the second lower cut valve portion 134 are provided with water through holes, respectively. The pipeline main body 1 is divided into two water outlet channels by arranging the pipeline middle base 14 in the middle area, and the water outlet channels are respectively connected with the first water outlet 103 and the second water outlet 104.

In this embodiment, the pipeline body 1 is provided with a monitoring hole for installing the sensor 2 for monitoring water quality, and the sensor 2 is arranged right above the pipeline middle base 14, so that the cleaning assembly 11 can be conveniently cleaned or scrubbed.

As shown in fig. 2 and 3, a first strong magnetic slider 1214 is fixedly connected to the first valve supporting rod 1210, and the first strong magnetic slider 1214 is disposed in the first valve control cavity 121; the second valve support rod 1220 is fixedly connected with a second strong magnetic slider 1224, and the second strong magnetic slider 1224 is arranged in the second valve control cavity 122. The first valve stem 1210 and the second valve stem 1220 have plugs 12101 at both ends thereof.

In this embodiment, the plug portion 12101 has a conical shape, and the water through holes of the first upper shut-off valve portion 131, the second upper shut-off valve portion 132, the first lower shut-off valve portion 133 and the second lower shut-off valve portion 134 have a conical shape, and the protruding portion of the plug portion 12101 can be engaged with the water through holes to block the water flow through the water through holes, thereby blocking or opening the pipeline.

In this embodiment, sealing portions 1211 are respectively disposed inside the first valve-controlled cavity 121 and the second valve-controlled cavity 122 near the water inlet/outlet pipeline, and the sealing portions 1211 are respectively and fixedly disposed with an electromagnet. The magnitude and direction of the current applied to the electromagnet are controlled to achieve the magnetic strength and direction of the electromagnet, and the first strong magnetic slider 1214 or the second strong magnetic slider 1224 are driven to slide, so that the first valve support rod 1210 or the second valve support rod 1220 is driven to slide, and the blocking or opening of the first upper blocking valve portion 131, the second upper blocking valve portion 132, the first lower blocking valve portion 133, or the second lower blocking valve portion 134 is achieved through the blocking portion 12101.

In this embodiment, there are four electromagnets, respectively, including a first upper electromagnet 1212, a first lower electromagnet 1216, a second upper electromagnet 1222, and a second lower electromagnet 1226.

In this embodiment, the electromagnet is fixedly mounted and connected with a damping member. The buffer components are buffer springs, and the buffer springs comprise four buffer springs, namely a first upper spring 1213, a first lower spring 1215, a second upper spring 1223 and a second lower spring 1225. The first upper spring 1213 is disposed between the first upper electromagnet 1212 and the first strong magnetic slider 1214, the first lower spring 1215 is disposed between the first strong magnetic slider 1214 and the first lower electromagnet 1216, the second upper spring 1223 is disposed between the second upper electromagnet 1222 and the second strong magnetic slider 1224, and the second lower spring 1225 is disposed between the second strong magnetic slider 1224 and the second lower electromagnet 1226.

When the magnitude and direction of the current acting on the electromagnet are controlled, the first strong magnetic slider 1214 or the second strong magnetic slider 1224 may slide under the action of magnetic attraction or repulsion, so as to avoid impact on the electromagnet, and the buffer spring may buffer the current to reduce the instantaneous impact force. The direction of gradually increasing the current can be adopted by controlling the current acting on the electromagnet, so that stronger instant attracting impact force is avoided.

As one possible embodiment, the first strong magnetic slider 1214 and the second strong magnetic slider 1224 may be electromagnets using current control.

The electromagnet is nonpolarity when no current control is carried out, and the phenomenon of magnetic attraction or repulsion cannot be generated.

As shown in fig. 4, the cleaning assembly 11 includes a cleaning impeller 1102, the cleaning impeller 1102 is connected with a cleaning shaft 1101, and a lower portion of the cleaning shaft 1101 is installed and arranged in the hole of the pipe middle base 14. The cleaning assembly 11 is further provided with a cleaning sheet assembly 1103, the cleaning sheet assembly 1103 comprises a brush rod, and a plurality of soft bristles are arranged on the brush rod.

In this embodiment, when deployed, the cleaning blade assembly 1103 is below the sensor measuring portion 201 on the sensor 2, and the soft bristles are in contact with the sensor measuring portion 201.

As shown in fig. 5, the cleaning impeller 1102 is a multi-bladed rotatable impeller, which is fixedly connected to the cleaning shaft 1101. In this embodiment, when water flows through, the washing impeller 1102 is impacted to rotate and drive the washing shaft 1101 to rotate, and the washing shaft 1101 is fixed in position by the supporting function of the pipe middle base 14. The cleaning sheet assembly 1103 is also fixedly connected to the cleaning shaft 1101, and at this time, the cleaning sheet assembly 1103 is driven by the cleaning shaft 1101 to rotate in a same step, and the soft bristles on the cleaning sheet assembly 1103 brush the measuring portion of the sensor 2.

In this embodiment, a sealing portion 1211 is also disposed at an inlet of the hole of the pipe middle base 14 for sealing the cleaning shaft 1101 and the hole of the pipe middle base 14.

As one of the possible implementation manners, the soft bristles may not directly contact with the sensor measuring portion 201, but may be spaced apart by a small distance, when the water flow impacts the cleaning impeller 1102 to drive the cleaning blade assembly 1103 to rotate, the cleaning shaft 1101 may also slightly move up and down in addition to synchronous rotation under the impact of the water flow, and when the water flow moves up, the soft bristles contact with the sensor measuring portion 201, thereby implementing the brushing and washing. This is more suitable for a situation where the sensor measuring part 201 is provided with a gas permeable membrane, such as a dissolved oxygen sensor based on the principle of electrochemical method, which can ensure effective decontamination and minimize the time for continuous contact brushing.

As shown in fig. 6, the pipe body 1 is further provided with a sewage draining outlet 15. The drain outlet 15 can be opened when needed to drain the residual water.

In this embodiment, when the electromagnet is controlled, the first valve stem 1210 or the second valve stem 1220 slides under the magnetic force, and may slide upward or downward. Therefore, at this time, only one of the first water inlet 101 and the first water outlet 103 is connected, the other is closed, only one of the second water inlet 102 and the second water outlet 104 is connected, and the other is closed, that is, only one end of the blocking portion 12101 at both ends of the first valve stem 1210 or the second valve stem 1220 plays a role of blocking.

In one preferred embodiment of the present invention, a water pump or other device is used to pump water in the water body to be detected to the first water inlet 101, and the direction and magnitude of the current acting on the first upper electromagnet 1212 or the first lower electromagnet 1216 are controlled, so that the first valve supporting rod 1210 slides downward under the driving of the first strong magnetic slider 1214, at this time, the first upper cutoff valve 131 is in an open state, and the first lower cutoff valve 133 is in a closed state; the pumped water flow enters the bidirectional water quality measuring pipeline device from the first water inlet 101.

Meanwhile, the direction and magnitude of the current applied to the second upper electromagnet 1222 or the second lower electromagnet 1226 are controlled, and the second strong magnetic slider 1224 slides upward, so that the second valve support rod 1220 slides upward, and the second upper cutoff valve portion 132 is in a closed state, and the second lower cutoff valve portion 134 is in an open state.

During the sliding process of the first strong magnetic slider 1214 and the second strong magnetic slider 1224, the first lower spring 1215 or the second upper spring 1223 can buffer the sliding, thereby avoiding the impact caused by too large magnetism. In practical implementation, the direction of the upper and lower electromagnets may be controlled so that one of the electromagnets magnetically attracts the first strong magnetic slider 1214 or the second strong magnetic slider 1224 therebetween and the other of the electromagnets magnetically repels the other electromagnet, so that the force applied to the blocking head portion 12101 is more tightly closed with the first upper shut-off valve portion 131, the second upper shut-off valve portion 132, the first lower shut-off valve portion 133 or the second lower shut-off valve portion 134. Preferably, a time delay control is also required, and the magnetic attraction is performed first, and when the closure is performed, the seal is reinforced by the magnetic repulsion. The plug portion 12101 may also be provided with a layer of sealing material.

When water enters the pipe body 1 from the first water inlet 101, the first lower stop valve 133 and the second upper stop valve 132 are closed, so that the water flows through the cleaning assembly 11 and then flows out to the second water outlet 104.

When water flows through the cleaning assembly 11, the cleaning impeller 1102 is impacted, so that the cleaning impeller 1102 starts to rotate, the cleaning shaft 1101 and the cleaning sheet assembly 1103 are driven to rotate together, and the measuring part on the sensor 2 is cleaned and brushed under the combined action of the soft bristles on the cleaning sheet assembly 1103 and the water flow.

In practical implementation, when the sensor 2 is a water quality sensor, such as a dissolved oxygen sensor of a galvanic cell method or a polarography method, there is a flow rate requirement on the water body to be measured when water quality measurement is performed.

Depending on the kind of sensor, during the non-measurement period, the opening or closing of the first upper cutoff valve portion 131, the second upper cutoff valve portion 132, the first lower cutoff valve portion 133, or the second lower cutoff valve portion 134 may be controlled by controlling the direction of the current applied to the first upper electromagnet 1212, the first lower electromagnet 1216, the second upper electromagnet 1222, or the second lower electromagnet 1226.

For example, the first upper stop valve portion 131 and the second upper stop valve portion 132 are all closed, at this time, the first lower stop valve portion 133 and the second lower stop valve portion 134 are all opened, the pipeline body 1 has residual water, and a part of the residual water flows out from the first water outlet 103 or the second water outlet 104, at this time, a very fine partial vacuum area is formed at the upper end of the inner cavity pipeline of the pipeline body 1, or at this time, a layer of air area is formed at the upper end of the inner cavity pipeline of the pipeline body 1. Therefore, during the non-measurement period, the water body may be selected not to contact the measurement portion of the sensor 2, and the sensor 2 is protected. According to the requirements of actual occasions, the water body can be kept in contact with the measuring part of the sensor 2 all the time.

In the practical implementation process, the pipeline main body 1 is in a sealed state, water flow of the water body enters the pipeline main body 1 from the first water inlet 101, and the water body is not in direct contact with air. Similarly, when the sensor 2 is a water quality sensor, for example, a dissolved oxygen sensor of a galvanic cell method or a polarography method, or a fluorescence method dissolved oxygen sensor, when pumping water to a water tank for detection, if the water body is in contact with air in the water pumping process, the accuracy of the measurement result is affected, and the bidirectional water quality measurement pipeline device of the scheme is also superior to the traditional water pumping detection mode.

The invention also comprises an electric part or an intelligent control part.

According to the bidirectional water quality measurement pipeline device, the sensor is cleaned and scrubbed synchronously in the measurement process, so that the sensor can be kept in a better measurement state, and the measurement data is more accurate.

According to the bidirectional water quality measurement pipeline device, the sensor does not need to be cleaned and maintained by periodically disassembling the device, the implementation mode of the technical scheme is more direct and convenient, the maintenance cost is reduced, and the service life of the sensor is prolonged.

According to the bidirectional water quality measuring pipeline device provided by the invention, the measuring pipeline device can be arranged in a sealing manner, water flow is not in direct contact with air, the measuring mode is more scientific, and the measuring result is more reliable and accurate.

The bidirectional water quality measurement pipeline device provided by the invention can select different water inlets and water outlets, is bidirectional and controllable, is more thorough to clean, and can adapt to different application scenes according to actual requirements.

According to the bidirectional water quality measurement pipeline device provided by the invention, a certain water flow speed is kept in the measurement process, the measurement result is scientific and effective, and the measurement result is more accurate for a part of specific sensors with requirements on the water flow speed.
