Description

Technical Field

[0001] The utility model relates to the technical field of water-saving gates, in particular to a water-saving gate capable of adjusting water flow for water conservancy irrigation. Background Art

[0002] In the northern region, crops are planted in small plots. When irrigating small plots, water in the irrigation channel flows to the fields. There is no sluice in the irrigation channel, which causes the fields close to the outlet to be completely irrigated, while the fields farther from the outlet have not yet been irrigated. The water resources are unevenly distributed. The water inlet between the channel and the field is opened or blocked manually. When the water flow is large, the blocked soil is easily washed away. For this purpose, application number: 201420686233.7 discloses a water-saving gate for an irrigation channel, which includes a gate and a frame. The gate is inserted in the inner grooves on the left and right sides of the frame. The gate is provided with two parallel opposing gates. The rack is meshed with a gear, which is connected to one end of the main shaft of the ratchet device, and a handwheel is provided at the other end of the main shaft. A pedal is sleeved in the middle of the main shaft, and the main shaft is connected to the top of the support rod, and the bottom end of the support rod is connected to the bottom side of the frame. When the device is in use, it is installed in the irrigation canal, the frame is tightly attached to both sides of the irrigation canal, the bottom of the frame is fixed to the bottom surface of the irrigation canal, and the support rod is also fixed to the bottom of the irrigation canal. The rotation of the pedal or handwheel causes the gear and the rack to move relative to each other, thereby raising or lowering the gate to adjust the water flow in the irrigation canal.

[0003] The water-saving gate for irrigation channels disclosed in the above patent can regulate and control the water flow in the irrigation channel by lifting or lowering the gate, but it still has some shortcomings during use: 1. The method of manually lifting or lowering the gate to regulate and control the water flow in the above patent is less accurate, and there is a situation where the water flow is larger or smaller due to the gate being raised or lowered too high or too low, thereby affecting the water irrigation effect; 2. The water-saving gate lacks a structure for filtering and collecting floating objects. When the gate is opened for irrigation, floating objects will follow the water flow into the field, thereby affecting the plants planted in the field; based on the above circumstances, the above patent is improved, and therefore the present application proposes a water-saving gate with adjustable water flow for water irrigation.

The wireless remote control switch and the second external remote control cooperate to remotely control the second brake motor 15;

[0029] The rear sides of the two mounting plates 100 are fixedly connected to the same water collecting cover 2, and the rear side of the water collecting cover 2 is connected and fixed with a flow sensor 3. The flow sensor 3 detects the flow of water flowing through, and its detection principle is the existing technology and will not be elaborated here. The rear side of the circular frame 1 is fixedly installed with a controller 11 and a solar power supply mechanism. The controller 11 has a built-in wireless synchronous control switch, which is electrically connected to the two first brake motors 10. The wireless synchronous control switch is matched with a first external remote control. The wireless synchronous control switch controls the two first brake motors 10 to start synchronously. The controller 11 is electrically connected to the flow sensor 3, and the solar power supply mechanism is electrically connected to the controller 11, the flow sensor 3, the two first brake motors 10 and the second brake motor 15, wherein the solar power supply mechanism includes a battery 13 fixedly connected to the rear side of the circular frame 1, the controller 11 is fixedly connected to the right side of the battery 13, and the top of the battery 13 and the top of the circular frame 1 are fixedly installed with the same inclined solar panel.

At the same time, the floating objects blocked by the filter can be scraped, collected and hoisted for cleaning, which is convenient for personnel to use.

[0030] Working principle: When in use, the entire device is fixed to the inner walls of the two sides of the canal through two mounting plates and external bolts. The sides of the two mounting plates 100 that are away from each other are in close contact with the inner walls of the two sides of the canal respectively. The bottom of the sealing rubber sleeve on the gate 101 is in active contact with the inner wall of the bottom of the canal, thereby isolating the water in the canal. When in use, the solar panel 12 collects external solar energy and converts it into electrical energy and stores it in the battery 13. The inverter 14 converts the DC power of the battery 13 into AC power to power the controller 11, the flow sensor 3, the first brake motor 10 and the second brake motor 15. The solar power supply method is convenient for personnel to operate the power supply.

[0031] The water flow required for irrigation is controlled in advance by the controller 11 according to the actual irrigation situation. When water conservancy irrigation is carried out, the wireless synchronous control switch is controlled by the first external remote controller to turn on the two first brake motors 10. The output shaft of the first brake motor 10 drives the corresponding gear 103 to rotate. While the gear 103 rotates, it drives the rack 102 meshing with it to move upward. The two racks 102 simultaneously drive the gate 101 to move upward. While the gate 101 moves upward, the water is blocked, allowing water to pass through the bottom of the gate 101, and through the water collection cover 2, through the flow sensor 3 and out into the canal. The water flows along the canal to the required position for water conservancy irrigation operation;

[0032] At the same time, the flow sensor 3 detects the water flow and transmits the detected flow value to the controller 11. When it is detected that the flow value reaches the preset value, the controller 11 controls the two first brake motors 10 to close. Under the locking force of the two first brake motors 10, the gate 101 is fixed. By electrically driving the gate 101 to rise and cooperating with the flow sensor 3 to detect the water flow, the water flow can be accurately controlled and adjusted, which can effectively reduce the situation where the water flow is too large or too small and affects the irrigation.

[0033] When water passes through the bottom of the gate 101, it will pass through the filter screen 4 in advance. The filter screen 4 filters the floating objects in the water and blocks them in front of it. The filter screen 4 filters and blocks the floating objects in the water, which can effectively prevent the floating objects from entering the fields. After a period of use, when it is necessary to clean the floating objects in front of the filter screen 4, the second external remote control is used to control the second brake motor 15 to open in the positive direction. The output shaft of the second brake motor 15 drives the winding roller 16 to rotate and rewind the traction rope 9. The traction rope 9 drives the filter box 5 to move upward through the pull ring 7 and the two connecting ropes 8 in turn. The filter box 5 drives the counterweight scraper 6 to move upward. The counterweight scraper 6 moves upward and scrapes the front side of the filter screen 4. Under the force, the floating objects on the front side of the filter screen plate 4 are scraped off and enter the filter box 5 along the counterweight scraper 6. While the filter box 5 moves upward, the water inside can be filtered out. When the filter box 5 moves upward to a suitable height, the staff can pull the filter box 5 to one side at the side of the canal to pour out the floating objects inside the filter box 5, thereby achieving the effect of collecting and pouring out the filtered floating objects for cleaning. After cleaning, the filter box 5 can be moved to the front side of the filter screen plate 4 again, and the second brake motor 15 can be turned on in the reverse direction. The second brake motor 15 drives the winding roller 16 to rotate to release the traction rope 9. Under the action of gravity, the filter box 5 and the counterweight scraper 6 move downward again and contact the inner wall of the bottom of the canal, and can wait for the next use operation.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
