[0029] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a channel irrigation metering gate system, including a gate assembly, an interception mechanism 5 and a garbage salvage lifting mechanism 4, the gate assembly is installed at the water outlet of the gate, the interception mechanism 5 and the garbage salvage lifting mechanism 4 are installed at the water inlet of the gate, and the garbage salvage lifting mechanism 4 is located at the back of the interception mechanism 5;

[0031] The interception mechanism 5 includes an interception box, which has a cavity inside. The interception box has an opening at one end away from the gate assembly, and the opening is connected to the cavity. The top and bottom of the interception box are respectively provided with strip holes 501, and the surface of the interception box is provided with a plurality of water leakage holes.

[0032] The garbage salvaging and lifting mechanism 4 includes a transmission belt 407, a plurality of salvaging plates 408 and a driving device. The transmission belt 407 is vertically arranged, and the driving device is used to drive the transmission belt 407 to operate;

[0033] The side of the transmission belt 407 close to the interception box passes through the strip hole 501 on the interception box, and a plurality of salvage plates 408 are evenly connected to the transmission belt 407 along the circumference of the transmission belt 407, and the strip hole 501 can allow the salvage plates 408 to pass through.

[0034] Specifically, the garbage flows toward the water inlet end of the gate along with the water flow, and the interception box intercepts the garbage floating on the water surface. At the same time, the driving device is turned on to drive the transmission belt 407 to rotate continuously. The salvage plate 408 on the transmission belt 407 moves with the rotation of the transmission belt 407, thereby continuously fishing out the garbage in the interception box, thereby achieving the effect of intercepting the garbage and fishing out the garbage in real time.

[0035] The interception box serves to intercept garbage and prevent it from entering the gate and causing clogging. At the same time, as the transmission belt 407 keeps running, the salvage plate 408 on the transmission belt 407 continuously fishes out the garbage in the interception box, so that the garbage will not accumulate in the interception box, the water flow through the gate will not be affected, and the accuracy of water metering is guaranteed.

[0036] As a preferred embodiment, Figure 1 and Figure 2 As shown, the channel irrigation metering gate system includes a gate body 9, a gate mouth is formed in the gate body 9, a gate plate assembly is installed at the water outlet end of the gate body 9, and a garbage salvage lifting mechanism 4 is installed on the end face of the water inlet end of the gate body 9, and an interception box is located in front of the garbage salvage lifting mechanism 4 and in front of the water inlet end of the gate mouth.

[0037] The water first passes through the interception box, and the garbage on the water surface is blocked by the interception box. At the same time, the garbage salvage and lifting mechanism 4 continuously salvages the garbage in the interception box, and the water enters the gate after passing through the interception box and the transmission belt 407.

[0038] As a preferred embodiment, Figure 1 , Figure 3 and Figure 4 As shown, the interception box is a rectangular box, with an opening in the front of the interception box, and strip holes 501 are respectively provided on the top and bottom of the interception box. Further, the front half of the transmission belt 407 passes through the strip holes 501 on the top and bottom of the interception box.

[0039] Specifically, the strip hole 501 is close to the back of the interception box. This is because most of the garbage is blocked by the back of the interception box, so most of the garbage tends to gather near the back of the interception box. The strip hole 501 is set here, making it easier for the salvage plate 408 to salvage the pull piece.

[0040] It should be noted that, considering that the conventional belt transmission belt has no holes thereon, such a transmission belt will affect the normal flow of water to a certain extent. Therefore, the transmission belt 407 in this embodiment is as follows: Figure 4 As shown, a plurality of water-permeable holes are evenly provided on the surface of the transmission belt 407. In this way, water flow can directly pass through the transmission belt 407 and enter the gate.

[0041] Preferably, Figure 1 and Figure 4 As shown, two support frames 404 are installed on the upper surface of the water inlet end of the gate body 9, and two fixed plates 402 are installed on the end surface of the water inlet end of the gate body 9. The support frames 404 are higher than the fixed plates 402. The fixed plates 402 are located on both sides of the gate, and the two fixed plates 402 are symmetrically arranged about the gate, and the two support frames 404 are symmetrically arranged about the gate. Further, the driving device includes an active roller 403, a driven roller 401, an active wheel 405 and a driving motor 406. Among them, the active roller 403 is rotatably installed between the two support frames 404, the driven roller 401 is rotatably installed between the two fixed plates 402, the active wheel 405 is coaxially installed on the active roller 403, the driven wheel is coaxially installed on the driven roller 401, the transmission belt 407 is transmission-installed between the active wheel 405 and the driven wheel, and the driving motor 406 is installed on the support frame 404, and its output end is connected to the active roller 403.

[0042] In this way, the driving motor 406 drives the active roller 403 to rotate, and the active roller 403 rotates to drive the active wheel 405 to rotate, so that the transmission belt 407 starts to rotate, and the rotation of the transmission belt 407 drives the driven roller 401 and the driven wheel to rotate together.

[0043] Optionally, the transmission belt 407 may be replaced by a chain, and the corresponding driving wheel 405 and the driven wheel may also be replaced by sprocket wheels.

[0044] Preferably, Figure 3 and Figure 4 As shown, the salvage plate 408 is a long strip plate, which is horizontally mounted on the transmission belt 407. The salvage plate 408 includes a first plate body and a second plate body connected to each other, and an angle is formed between the first plate body and the second plate body, which is an obtuse angle. In this way, when salvaging garbage, the garbage is limited in the angle between the first plate body and the second plate body, and is not easy to roll down, thereby improving the accuracy of salvaging garbage.

[0045] Further, such as Figure 4 As shown, when the salvage plate 408 located below the water level rotates to above the water level, a certain amount of water will accumulate on the salvage plate 408, which is not conducive to the salvage effect. Therefore, a plurality of holes are evenly opened on the surface of the salvage plate 408. In this way, water will not accumulate on the salvage plate 408, thereby improving the efficiency of salvaging garbage.

[0046] As a preferred embodiment, Figure 1 , Figure 2 and Figure 3As shown, a garbage collection box 6 is installed on the top of the gate body 9, and the garbage collection box 6 is close to the top position of the transmission belt 407 and is located on the back of the transmission belt 407. In this way, the salvage plate 408 rotated to the top of the rotating belt 407 will throw the garbage into the garbage collection box 6, which plays the role of collecting garbage.

[0047] Optionally, one side of the garbage collection box 6 close to the transmission belt 407 is an inclined surface to reduce the height of the garbage collection box 6 close to one end of the transmission belt 407 so that the garbage can be thrown into the garbage collection box 6 more easily.

[0048] Preferably, Figure 3 and Figure 4 As shown, a plurality of connecting plates 502 are respectively fixed on the left and right sides of the interception box, and the other ends of the connecting plates 502 are fixed on the end surface of the water inlet end of the gate body 9.

[0049] As a preferred embodiment, the canal irrigation metering gate system includes a flow meter, a system host 8 and a solar panel 7. The flow meter is installed in the gate, the system host 8 is installed on the top of the gate body 9 or placed on the shore, and the solar panel 7 is installed on the top of the system host 8. The system host 8 and the flow meter are connected using a waterproof data transmission line. The system host 8 includes a data storage device, a battery, a signal transmitter and receiver, and a circuit control device. The solar panel 7 converts light energy into electrical energy and stores it in the battery, which supplies power to the drive motor 406, the winch unit 3, and the system host 8.

[0050] As a preferred embodiment, Figure 2 As shown, the gate assembly includes a gate 1, a mounting frame 2 and a hoisting unit 3. The mounting frame 2 is arranged at the water inlet end of the gate body 9. The gate 1 is slidably mounted in the mounting frame 2. The height of the gate 1 is greater than the height of the gate. The hoisting unit 3 is mounted on the top of the mounting frame 2 and is used to lift the gate 1. The gate is opened by raising the height of the gate 1 through the hoisting unit 3, and the gate is closed by lowering the height of the gate 1. It should be noted that the gate assembly can use gate assemblies of other structures on the market.
