Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and irrigation technology, specifically relating to a water conservancy irrigation area channel control device. Background Technology

[0002] Irrigation districts are technical facilities used to meet the water needs of agricultural and forestry production. They are an important component of agricultural water conservancy projects. Canals are a component of irrigation districts. When using canals to divert water for irrigation, it is necessary to control the opening and closing of the canals by controlling valves in order to regulate the water resources of the irrigation district.

[0003] Traditional gate lifting mechanisms often lack dedicated guiding structures, relying solely on the simple fit between the gate and the base for positioning. Under the impact of water flow, these mechanisms are prone to tilting and shifting, leading to increased gaps between the gate and the base, causing leakage and wasting water resources. Furthermore, during water discharge, aquatic organisms such as fish and shrimp are easily swept up to the vicinity of the gate by the water flow. Due to the impact of the water flow, the pressure of the gate, or entanglement with debris, a large number of organisms die, disrupting the ecological balance of the irrigation area. Some fish and shrimp may even enter the irrigation area with the water flow, unable to adapt to the farmland water environment and potentially causing harm to crop growth, posing problems in their use. Utility Model Content

[0004] To address the shortcomings mentioned in the prior art, this utility model provides a water conservancy irrigation area channel control device.

[0005] This application proposes a canal control device for irrigation districts, comprising two bases, with support columns fixedly installed on the top surface of the bases, and the top surfaces of the two support columns fixedly connected by a connecting block. Winches are fixedly installed on both sides of the top surface of the connecting block, with steel wire ropes wound on the winches. A lifting gate is slidably installed between the two bases, and a guide limiting component is installed between the lifting gate and the base. One end of the steel wire rope is fixedly connected to the top surface of the lifting gate, and a guide rod is fixedly installed at the front end of the top surface of the connecting block. A guide wheel is rotatably installed at the front end of the guide rod, and the steel wire rope passes around the guide wheel.

[0006] Specifically, the guide limiting component includes a set of guide blocks fixedly installed on the opposite surfaces of two bases. Each set of guide blocks consists of two guide blocks, one upper and one lower. Guide grooves are opened on both sides of the lifting gate, and the bottom of the guide grooves communicates with the outside. The guide blocks can be inserted into the corresponding guide grooves.

[0007] Specifically, a first interception mesh frame is fixedly installed at the rear of the base, and the rear ends of the two first interception mesh frames are fixedly connected by a second interception mesh frame. Interception meshes are fixedly installed inside both the first and second interception mesh frames.

[0008] Specifically, an L-shaped groove is formed inside the base. The rear end opening of the longitudinal groove of the L-shaped groove is located at the rear of the base, and the transverse groove opening of the L-shaped groove is located on one side of the base. A return pipe is fixedly installed on one side of the base, and two bases are located between two return pipes. One end of the return pipe is fixedly connected to the transverse groove opening of the L-shaped groove.

[0009] Specifically, the reflux pipe consists of a first pipe and a second pipe, which are fixedly connected. One end of the first pipe is fixedly connected to the transverse groove opening of the L-shaped groove, and the connection between the first pipe and the second pipe is an obtuse angle.

[0010] Compared with the prior art, the present invention has the following beneficial effects: When water needs to be released, the winch winds up the wire rope, the lifting gate moves upward, and a gap appears between the two bases. Water in the irrigation area flows out from the gap between the two bases and moves up and down vertically through the guide limiting component. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] A water conservancy irrigation area canal control device, such as Figure 1As shown, the system includes two bases 1, with support columns 2 fixedly installed on the top surface of the bases 1. The top surfaces of the two support columns 2 are fixedly connected by a connecting block 3. Winches 4 are fixedly installed on both sides of the top surface of the connecting block 3, and steel wire ropes are wound on the winches 4. A lifting gate 5 is slidably installed between the two bases 1. A guide limiting component is installed between the lifting gate 5 and the base 1. One end of the steel wire rope is fixedly connected to the top surface of the lifting gate 5. A guide rod is fixedly installed at the front end of the top surface of the connecting block 3. A guide wheel is rotatably installed at the front end of the guide rod, and the steel wire rope passes around the guide wheel.

[0015] Two bases 1 are fixedly installed on both sides of the outlet of the channel. Both bases 1 and support columns 2 are made of concrete. When water needs to be released, the winch 4 winds up the wire rope, the lifting gate 5 moves upward, and a gap appears between the two bases 1. Water in the irrigation area flows out from the gap between the two bases 1. Through the guide limiting component, the lifting gate 5 moves up and down vertically.

[0016] Specifically, the guide limiting component described in this embodiment includes two bases 1 with a set of guide block groups 6 fixedly installed on their opposite sides. Each set of guide block groups 6 consists of two guide blocks, one upper and one lower. Guide grooves 7 are opened on both sides of the lifting gate 5. The bottom of the guide grooves 7 is connected to the outside. The guide blocks can be inserted into the corresponding guide grooves.

[0017] As the lifting gate moves upward, the lowest guide block in the guide block assembly moves out of the guide groove, while the highest guide block remains within the guide groove. A distance sensor is installed on the highest guide block to monitor the rising height of the lifting gate. When a threshold is reached, the winch stops winding the cable, and the lifting gate stops moving upward. The guide blocks are inserted into the guide grooves. During the up-and-down movement of the lifting gate 5, the cooperation between the guide blocks and the guide grooves guides the lifting gate 5, preventing it from tilting during movement. Furthermore, when the lifting gate is placed between the two bases, the guide block assembly limits its movement, preventing it from tilting due to water flow impact and potential leakage.

[0018] Furthermore, in this embodiment, a first interception net frame 8 is fixedly installed on the rear of the base 1, and the rear ends of the two first interception net frames 8 are fixedly connected by a second interception net frame 9. Interception nets are fixedly installed inside both the first and second interception net frames.

[0019] like Figure 1 As shown, the intercepting nets within the first and second intercepting net frames can intercept fish, shrimp, garbage, etc., preventing them from flowing out through the gap between the two bases.

[0020] Furthermore, in this embodiment, an L-shaped groove 10 is formed in the base 1. The rear end opening of the longitudinal groove of the L-shaped groove 10 is located behind the base 1, and the transverse groove opening of the L-shaped groove 10 is located on one side of the base 1. A return pipe 11 is fixedly installed on one side of the base 1, and two bases are located between two return pipes 11. One end of the return pipe is fixedly connected to the transverse groove opening of the L-shaped groove.

[0021] like Figure 1 As shown, the transverse opening of the L-shaped groove on the left side of the base is located on the left side of the base, and the transverse opening of the L-shaped groove on the right side of the base is located on the right side of the base. When fish and shrimp are brought to the base by the water flow, they can enter the L-shaped groove 10 through the longitudinal opening of the L-shaped groove 10, and then continue to swim into the return pipe 11, and swim out through the other end of the return pipe 11, away from the base.

[0022] Furthermore, the return pipe 11 described in this embodiment is composed of a first pipe and a second pipe. The first pipe and the second pipe are fixedly connected. One end of the first pipe is fixedly connected to the transverse groove opening of the L-shaped groove. The connection between the first pipe and the second pipe is an obtuse angle.

[0023] The connection between the first and second pipes is at an obtuse angle, ranging from 90 to 140 degrees. This angle can guide fish and shrimp away from the outlet of the channel, that is, guide them to a position where the water flow is relatively gentle.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
