As shown in fig. 1-3, an embodiment of the present invention provides a control and measurement integrated gate suitable for drainage of a rough canal, including a weir notch 1, a gate frame 2, a triangular weir plate 3, a hand-inserted gate plate 4 and a trash rack 5, wherein the trash rack 5 is disposed on a water inlet side of the weir notch 1, the triangular weir plate 3 is disposed on a water outlet side, the gate frame 2 is disposed in front of the trash rack 5, a plurality of opening adjusting holes 6 are formed in the hand-inserted gate plate 4, the hand-inserted gate plate 4 is adjustably inserted into the opening adjusting holes 6 by opening control inserts 7, and a water level gauge 10 is further disposed in the weir notch 1. And (3) fixing the gate frame 2 at a water outlet of a channel through screws 11, and enabling water to flow through the weir groove 1 to the triangular weir plate 3 and then enter the field. The trash rack 5 is used for preventing the objects such as weed, wood, stone, clothes, plastics and the like from entering the weir notch 1 to influence the measurement of the overflow and the water level gauge 10. Open on hand formula flashboard 4 of inserting has a plurality of apertures regulation hole 6, the flow control that conveniently drains, adopts the mode of pegging graft in addition, easy to assemble to effectively solve the rural field ditch problem that can not control, do not install well, do not have the measurement in the aspect of draining.

In this embodiment, a gate plate groove is formed in the gate frame 2, the hand-inserted gate plate 4 is inserted into the gate plate groove of the gate frame 2 and can slide along the gate plate groove, and finally the hand-inserted gate plate 4 can be fixed on the gate frame 2 by the opening control insertion 7. It should be noted that the gate frame 2 and the gate plate groove can be made of steel materials and have certain elasticity, and the hand-inserted gate plate 4 is embedded in the gate plate groove, so that water stopping can be realized without using a rubber sealing strip.

In this embodiment, the device further comprises a slotting chain 8, one end of the slotting chain 8 is connected to the opening control slotting 7, and the other end of the slotting chain 8 can be connected to the gate frame 2 or the hand-inserted gate 4, so as to prevent the opening control slotting 7 from being lost.

In this embodiment, the gate frame 2 is further marked with an opening mark line 9, and the opening mark line 9 corresponds to the opening adjusting hole 6 and is also divided into 4 steps of "large, medium, small and closed", so that the flow rate of discharged water is convenient to control.

In this embodiment, the angle of the triangular weir plate 3 is preferably 90 degrees, which can be designed according to specific situations, but a specification table needs to be searched separately according to the flow data.

In this embodiment, the upper end of the hand-inserted gate 4 is a handle 41, the middle part is a connecting plate 42, the lower part is a baffle 43, the opening degree adjusting hole 6 is arranged on the connecting plate 42, and further, the handle 41 is a circular pipe, which is convenient for hand-held control. The opening degree adjusting holes 6 are divided into 4 grades of large, medium, small and closed, and the water discharge flow is convenient to control. Further, the connecting plate 42 and the baffle 43 are integrally formed, and may be cut from a steel plate.

The gate using mode is that after gate frame 2 is fixed in the import department of channel outlet pipe, realize through aperture control slotting 7 that hand formula flashboard 4 different apertures (big, well, little, close) are inserted to the realization gets into that the flow of irrigation water is controllable in the weir groove 1, satisfies terminal triangle weir plate 3 on the one hand and goes out the water requirement, and on the other hand has also satisfied the different water demand of field irrigation drain. Through the field person's that drains water with water observation, record different time quantum water level gauge 10 readings, through consulting "right angle triangle weir flow table" (table 1 promptly), can realize the purpose of farmland drainage control flow and calculation water consumption. Considering that the actual recording time is generally days and hours, and is as thin as minutes at most, three unit flow data of cubic meter/minute, cubic meter/hour and cubic meter/day (24 hours) are converted by the right-angle triangular weir flow meter on the basis of the original standard common unit 'liter/second', so that the table lookup for actual operation is convenient. Under the condition that the water is relatively stable, the water consumption can be estimated only by recording the water discharging time of different opening degrees of the water inlet gate through water discharging recording analysis in a certain period, and the inconvenience and the rapidness of recording a graduated scale and looking up 'right-angle triangular weir flow table' for detailed calculation are avoided.

TABLE 1 Right-angled triangular weir flowmeter

In order to avoid influencing the overflowing of the weir crest 1 and the upstream silting of the triangular weir plate 3, the weed sundries at the trash rack 5 and the fine sand sludge in the weir crest 1 are cleaned frequently; the embodiment of the invention provides a control and measurement integrated gate suitable for the drainage of a main canal, which is generally suitable for the drainage of the main canal in the field with the depth of 30cm or less, otherwise, the gate structure is inconvenient for manually opening and closing the gate plate, and the stability of water flow cannot be realized by using a shorter weir groove; the weir notch 1 and the triangular weir plate 3 can be formed by pressing and welding steel plates with the thickness of 2-3 mm or cutting and adhering hard plastic plates with the thickness of 5 mm, and the field rough channel can be normally poured on two sides of the weir notch and the consequent sections; the water level gauge 10 is arranged at the stable position of the upstream water flow of the triangular weir plate 3, the initial 0 scale is flush with the right-angled vertex of the triangular weir plate 3, and the reading of the scale is guaranteed to be the H value of the weir height; the length of an upstream weir notch of the triangular weir plate 3 is required to meet the requirement that the channel width is at least more than 5 times, so that the water flow is ensured to be stable, and the observation and measurement of the triangular weir are accurate; conditionally, an automatic water level meter can be installed, and the relation among time, water level and flow is set to replace manual observation, but the current cost condition and the convenience in popularization are considered, and the manual observation is more consistent with the characteristics of low price, convenience and strong adaptability. The utilization efficiency and the effect of the farmland irrigation water can be improved, and the obvious economic benefits of water saving and efficiency improvement are achieved; on the other hand, the water quality and the field appearance in rural areas can be improved, and the environment and the social benefits for promoting the construction of beautiful villages and beautiful gardens are achieved.
