Description

Technical Field

[0001] This utility model belongs to the field of water conservancy channel technology, specifically relating to a water-saving structure for irrigation area water conservancy channels. Background Technology

[0002] In the construction and operation of irrigation district water conservancy projects, water conservancy channels, as key carriers of water resource transportation, directly affect the efficiency of water resource utilization and the cost of project maintenance due to the rationality of their structural design. Existing irrigation district water conservancy channel structures have several limitations: Firstly, traditional channel interfaces are mostly fixed, making it difficult to flexibly adjust according to terrain changes and actual water transport needs. For example, in hilly areas with complex terrain or when expanding irrigation areas, fixed interfaces cannot easily change the direction of water flow or extend the channel, leading to a disconnect between channel layout and actual needs, resulting in low water resource transportation efficiency. If idle interfaces are not effectively sealed, water leakage and the entry of external impurities can occur, affecting water quality. Secondly, existing channels also have shortcomings in maintenance and cleaning. Cleaning internal debris often requires dismantling the entire structure, which is cumbersome, time-consuming, and labor-intensive, increasing maintenance costs and potentially damaging structural components due to frequent disassembly. Furthermore, traditional sealing structures are simple and cannot effectively withstand water pressure, easily leading to leakage and water waste. Therefore, this paper proposes a water-saving structure for irrigation canals to solve the aforementioned problems in existing technologies and improve the overall benefits of irrigation projects. Utility Model Content

[0003] This utility model addresses the problems of the prior art by providing a water-saving structure for irrigation canals.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A water-saving structure for irrigation canals includes a shell. Drainage ports are symmetrically installed on both sides of the rear end of the shell. Extensions and sealing caps can be detachably installed at the ports to adapt to different irrigation terrains and water-saving needs. A movable cover plate is hinged to the upper surface of the rear end of the shell. When the movable cover plate is opened, a cleaning port is formed at the top of the shell for cleaning the interior of the shell.

[0006] Preferably, a filter grille is fixedly installed at the connection between the drain port and the water flow channel inside the shell.

[0007] Preferably, the edges of the drainage port, the extension, and the sealing cap are all fixedly provided with connecting frames.

[0008] Preferably, the movable cover is connected to the housing via a connecting component and rotates around a hinge point. The surface of the movable cover is provided with a handle, and a sealing component is fixedly installed on the contact edge between the movable cover and the housing.

[0009] Preferably, the front end of the housing is provided with a water inlet, the size of which is adapted to an external water source pipe.

[0010] Preferably, the shell has a segmented structure, with a through water flow channel formed inside the shell, and the shell is spliced ​​into multiple segments through the connecting frame.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. The diversion port can be selectively fitted with extension parts or sealing caps through the connecting frame, which can change the direction of water flow, extend the channel, and close unused interfaces. Compared with the traditional fixed interface design, it is more flexible and can cope with complex and varied irrigation area terrain and water-saving needs.

[0013] 2. The cleaning port design formed after the movable cover is opened allows operators to directly enter the housing for cleaning without disassembling the entire structure. At the same time, the sealing components on the edge of the movable cover, together with the silicone strip design, can effectively prevent water leakage. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1-4 As shown, this application discloses a water-saving structure for irrigation canals, including a shell 1. The shell 1 is segmented, with symmetrical inlets 4 installed on both sides of the rear end of the shell 1. A connecting frame 6 is fixedly installed at the edge of the outlet of the inlet 4. The shell 1 can be spliced ​​into multiple sections through the connecting frame 6, flexibly expanding according to the length of the canal. The interior of the shell 1 is a water flow channel, and the inlets 4 are connected to the water flow channel inside the shell 1. A filter grille 5 is fixedly installed at the connection between the inlet 4 and the shell 1. The filter grille 5 is used to intercept debris in the water flow and prevent it from entering the subsequent irrigation canal and causing blockage. The front end of the shell 1 has an inlet 2, which is used to connect to an external water source pipe, allowing water to flow smoothly into the water-saving structure. The size and shape of the inlet 2 are adapted to the connecting pipe. A movable cover plate 3 is provided on the upper surface of the rear end of the shell 1. The movable cover plate 3 is hinged to the shell 1 through a connecting component 33. The movable cover plate 3 can rotate around the connection point to realize the opening and closing function. A handle 31 is also installed on the movable cover plate 3 for easy operation. The movable cover 3 is opened and closed. A sealing component 32 is fixedly installed at the contact edge between the movable cover 3 and the housing 1. The sealing component 32 has several small holes through which bolts can be fixed. A silicone strip is fixed to the inner edge of the movable cover 3. When the movable cover 3 is closed, the sealing component 32 can effectively prevent water seepage. When the movable cover 3 is opened, the opening presented is the cleaning port 7. The setting of the cleaning port 7 facilitates the regular cleaning of the interior of the water-saving structure, removing garbage in the water source and weeds near the irrigation area, ensuring smooth water flow. According to actual engineering needs, an extension 8 or a sealing cover 9 can be selectively installed at the port of the diversion port 4. Both the extension 8 and the sealing cover 9 are fixedly provided with a connecting frame 6 at their edges, and the structure is the same as the connecting frame 6 at the edge of the diversion port 4, ensuring that the connection does not leak. The extension 8 is used to extend the water flow channel or change the water flow direction. The sealing cover 9 is used to close the diversion port 4 on the housing 1 when it is not in use, preventing water leakage and the entry of external impurities, and ensuring the sealing performance of the water-saving structure. Figure 4As shown, the shell 1 is tilted at a certain angle. Irrigation channels are often built along the terrain and have a natural slope. The tilt angle of the shell can be consistent with the overall slope of the channel, so that the water-saving structure can be integrated into the terrain, reducing the amount of earthwork excavation and construction costs. For example, in the channel in the hilly area, the tilted shell can avoid the water flow obstruction caused by the undulating terrain.

[0023] During the construction phase of the water conservancy channel, steel or concrete embedded parts are pre-embedded in the bottom and side walls of the channel according to the installation position and size of the shell 1. These embedded parts have bolt holes or grooves. After the shell 1 is transported to the location, the shell 1 is connected and fixed to the embedded parts with bolts. During operation, external water flows into the water flow channel inside the shell 1 through the inlet 2. The shell 1 can be extended by splicing the connecting frame 6 on the edge of the diversion port 4 to adapt to the channel length. The water flows in the shell 1 to the diversion port 4, where the fixed filter screen 5 intercepts mud, sand, weeds and other debris to prevent blockage of the downstream channel. According to actual needs, the extension part 8 is installed at the port of the diversion port 4 through the connecting frame 6 to change the water flow direction or extend the channel, or the unused diversion port is sealed with a sealing cover 9 to ensure structural sealing. When it is necessary to clean the inside, the operator rotates the movable cover plate 3 hinged to the shell 1 by the handle 31 to open the cleaning port 7 and remove the deposited debris.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
