Description

Technical Field

[0001] This application relates to the field of irrigation equipment technology, specifically a water conservancy irrigation district channel control device. Background Technology

[0002] Irrigation districts are semi-artificial ecosystems that typically draw water from one or more sources and have complete water conveyance, distribution, irrigation, and drainage systems. Their primary function is agriculture, improving overall agricultural productivity by providing favorable water, soil, fertilizer, air, and heat conditions for crop growth.

[0003] Irrigation canal control devices are key equipment used in irrigation canal systems to achieve precise control and distribution of water flow, ensuring that water resources are delivered to farmland according to the irrigation plan, improving irrigation efficiency, reducing water waste, enhancing the irrigation area's ability to cope with disasters such as drought and flood, maintaining the stable operation of the irrigation system, and providing a solid guarantee for stable and high agricultural production. However, existing technologies often use water gates to regulate water flow in irrigation areas. However, when the gates are opened to release water into the fields, fish, shrimp, garbage, etc., will follow the water flow into the fields. Fish and shrimp will eat crop roots and stems, and garbage will pollute the soil, which may have an adverse effect on crop growth.

[0004] Therefore, this application provides a canal control device for irrigation districts to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a water conservancy irrigation area channel control device, which aims to solve the problems mentioned in the background art, such as the inability of existing gates to intercept fish, shrimp and garbage, which may have an adverse effect on crop growth.

[0006] To achieve the above objectives, this application provides the following technical solution: a water conservancy irrigation district channel control device, comprising:

[0007] A water channel, wherein a support is fixedly installed inside the water channel, and a flow cavity is opened inside the water channel;

[0008] A closing mechanism, located inside the two supports and used to close the flow cavity;

[0009] An interception mechanism is located at the top of the irrigation canal and is used to intercept the flow cavity. The interception mechanism includes two symmetrically arranged connecting blocks fixedly installed on a support. An interception frame is rotatably installed between the two connecting blocks. An interception plate is fixedly installed inside the interception frame. The interception plate has several evenly distributed flow holes. In use, the interception frame is lowered so that the interception plate extends into the irrigation canal. The electric push rod is activated, which drives the telescopic rod to extend and retract, thereby raising the gate inside the support to release water. The water flows through the flow holes on the surface of the interception plate, passes through the gate, and flows into the field. The interception plate intercepts garbage, fish, and shrimp, preventing them from entering the field and ensuring the normal growth of crops.

[0010] Preferably, the closing mechanism includes a gate slidably installed inside two brackets and an electric push rod fixedly installed on the brackets. The telescopic end of the electric push rod is connected to a telescopic rod, and the bottom of the telescopic rod is fixed to the gate.

[0011] Preferably, in order to stabilize the support, symmetrically arranged support plates are fixedly installed on one side of the support, and both support plates are fitted against the two walls inside the flow cavity to improve the stability of the support.

[0012] Preferably, in order to improve the support strength, a number of evenly distributed reinforcing ribs are fixedly installed inside the interception frame. The reinforcing ribs are fixedly installed at the bottom of the interception plate to improve the stability of the interception plate.

[0013] Preferably, in order to stabilize the interception plate, a gravity block is fixedly installed at the bottom of the top of the interception frame away from the connecting block. The gravity block is adapted to the bottom of the flow cavity to prevent the interception frame from being lifted by the water flow and to ensure interception efficiency.

[0014] Preferably, for ease of cleaning, two symmetrically arranged support seats are fixedly installed on both sides of the top of the water channel, and a rotating shaft is rotatably installed between the two support seats. A drive motor is fixedly installed on one side of one of the support seats, and the output end of the drive motor is fixedly connected to the rotating shaft. A handle is fixedly installed on the end of the interception frame away from the connecting block, and a rope is connected to the outer wall of the handle. The end of the rope relative to the handle is wrapped around the rotating shaft to prevent blockage of the flow hole, so as to ensure smooth water flow next time.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention utilizes the cooperation of a closing mechanism and an interception mechanism. Lowering the interception frame allows the interception plate to extend into the irrigation canal. Activating the electric push rod drives the telescopic rod to extend and retract, thereby raising the gate within the support structure to release water. The water flows through the flow holes on the surface of the interception plate, passes through the gate, and is discharged into the fields. The interception plate intercepts garbage, fish, and shrimp, preventing them from entering the fields and ensuring normal crop growth. After water release, closing the gate and activating the drive motor rotates the shaft, winding up the rope and pulling up the handle. This causes the interception frame to rotate and rise around the connecting block, exposing it above the water surface. This facilitates cleaning personnel removing garbage from the interception plate, preventing blockage of the flow holes and ensuring smooth water flow next time. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] like Figure 1 - Figure 4 As shown, this embodiment provides a water conservancy irrigation district canal control device, which includes:

[0026] Water channel 1, with a support 2 fixedly installed inside the water channel 1, and a flow cavity opened inside the water channel 1;

[0027] A closing mechanism is located inside the two supports 2 and is used to close the flow cavity;

[0028] The interception mechanism 3 is located at the top of the water channel 1 and is used to intercept the flow cavity. The interception mechanism 3 includes two symmetrically arranged connecting blocks 31 fixedly installed on the bracket 2. An interception frame 32 is rotatably installed between the two connecting blocks 31. An interception plate 33 is fixedly installed inside the interception frame 32. Several evenly distributed flow holes 34 are opened on the interception plate 33. The closing mechanism includes a gate 21 slidably installed inside the two brackets 2 and an electric push rod 22 fixedly installed on the bracket 2. The telescopic end of the electric push rod 22 is connected to a telescopic rod 23. The bottom of the telescopic rod 23 is fixed to the gate 21.

[0029] When in use, the interception frame 32 is lowered so that the interception plate 33 extends into the water channel 1. The electric push rod 22 is activated, which drives the telescopic rod 23 to extend and retract, thereby raising the gate 21 in the bracket 2 to release water. The water flows through the flow holes 34 on the surface of the interception plate 33 and passes through the gate 21 to be discharged into the field. The interception plate 33 intercepts garbage, fish and shrimp to prevent them from entering the field and ensures the normal growth of crops.

[0030] It is understandable that the interceptor plate 33 can increase the contact area by inserting its inclined surface into the water channel 1, thereby reducing the probability of blockage.

[0031] Specifically, a symmetrically arranged support plate 24 is fixedly installed on one side of the bracket 2. Both support plates 24 are fitted against the two walls inside the flow cavity. In use, the bracket 2 is inserted into the water channel 1, the support plate 24 is placed close to the water channel 1, and the support plate 24 is fixed in the water channel 1 with bolts to stably support the bracket 2 in the water channel 1, thereby improving the stability of the bracket 2.

[0032] More specifically, a number of evenly distributed reinforcing ribs 35 are fixedly installed inside the interception frame 32. The reinforcing ribs 35 are fixedly installed at the bottom of the interception plate 33. When in use, the reinforcing ribs 35 support the interception plate 33 from the bottom, thereby improving the stability of the interception plate 33 when water flow impacts the interception plate 33.

[0033] Furthermore, a gravity block 36 is fixedly installed at the bottom of the top of the interceptor frame 32 away from the connecting block 31, and the gravity block 36 is adapted to the bottom of the flow cavity.

[0034] When in use, the gravity block 36 increases the weight of the other end of the interception frame 32, so that the interception frame 32 can be more stably pressed against the water channel 1, preventing the interception frame 32 from being lifted by the water flow and ensuring interception efficiency.

[0035] Example 2

[0036] Unlike Embodiment 1, garbage accumulation on the interceptor plate 33 will cause blockage if not cleaned. Therefore, two symmetrically arranged support seats 37 are fixedly installed on both sides of the top of the water channel 1. A rotating shaft 38 is rotatably installed between the two support seats 37. A drive motor 311 is fixedly installed on one side of one of the support seats 37. The output end of the drive motor 311 is fixedly connected to the rotating shaft 38. A handle 39 is fixedly installed on the end of the interceptor frame 32 away from the connecting block 31. A rope 310 is connected to the outer wall of the handle 39. The end of the rope 310 relative to the handle 39 is wrapped around the rotating shaft 38.

[0037] In use, after releasing water, close the gate 21, start the drive motor 311 to drive the rotating shaft 38 to rotate, and reel in the rope 310 to pull up the handle 39. This causes the interception frame 32 to rotate and rise around the connecting block 31, so that the interception frame 32 is exposed above the water surface. This makes it easier for cleaning personnel to clean the debris on the interception plate 33 and prevent blockage of the flow hole 34, so that the next water flow can be smooth.

[0038] Working principle:

[0039] The device mainly consists of three parts: a water channel 1, a closing mechanism, and an interception mechanism 3. The closing mechanism is responsible for closing the flow cavity inside the water channel 1, thereby controlling the flow of water. The interception mechanism 3 is used to intercept the flow cavity, blocking debris and regulating the water flow. When it is necessary to control the flow of water in the water channel 1, the electric push rod 22 starts to work. The telescopic end of the electric push rod 22 drives the telescopic rod 23 to telescopically extend and retract. Since the bottom of the telescopic rod 23 is fixed to the gate 21, when the telescopic rod 23 extends, it will drive the gate 21 to slide downward inside the bracket 2 until the flow cavity is completely closed, at which point the water flow in the water channel 1 is blocked. When the telescopic rod 23 of the electric push rod 22 retracts, the gate 21 moves upward, the flow cavity opens, and the water flow in the water channel 1 resumes normal flow.

[0040] Under normal circumstances, the interception frame 32 relies on the action of the gravity block 36 to make its bottom fit with the bottom of the flow cavity, and the interception plate 33 is in a vertical state, which plays a role in intercepting the water flow in the water channel 1. The water flow can continue to flow through the flow hole 34 on the interception plate 33. At the same time, the interception plate 33 can block debris in the water, such as branches and weeds, to prevent these debris from entering the downstream channel and avoid clogging the downstream equipment or irrigation system.

[0041] When it is necessary to adjust the interception angle of the interception plate 33, the drive motor 311 is started. The drive motor 311 drives the rotating shaft 38 to rotate in the forward direction. The rope 310 will be wrapped around the rotating shaft 38. The rope 310 pulls the handle 39, causing the interception frame 32 to rotate around the connecting block 31. The interception plate 33 gradually tilts, thereby changing the water flow area and water flow direction, and realizing the adjustment of the water flow.

[0042] If the drive motor 311 drives the rotating shaft 38 to rotate in the opposite direction, the rope 310 will be released, and the intercepting frame 32 will gradually return to its initial vertical state under the action of the gravity block 36.

[0043] The symmetrical support plate 24 fixedly installed on one side of the bracket 2 is attached to the two walls inside the flow cavity, which serves to support and fix the bracket 2, ensuring the stability of the bracket 2 in the water channel 1, thereby ensuring that the closing mechanism and the interception mechanism 3 can work normally.

[0044] Several evenly distributed reinforcing ribs 35 are fixedly installed inside the interception frame 32 and fixed to the bottom of the interception plate 33, which enhances the structural strength of the interception plate 33, enabling it to withstand greater water flow impact and ensuring that the interception plate 33 will not deform or be damaged during long-term use.

[0045] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
