Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically a detachable and modular water channel for water conservancy engineering. Background Technology

[0002] Prefabricated irrigation canals are water conservancy facilities that are rapidly assembled on-site using prefabricated components. They are widely used in irrigation, drainage, and flood control projects. Their technological background stems from the problems of low construction efficiency, difficulty in quality control, and high costs associated with traditional irrigation canals. Through factory prefabrication and standardized production, prefabricated irrigation canals can significantly improve construction efficiency, ensure project quality, reduce project costs, and possess strong adaptability and environmental and energy-saving advantages. Their flexible design facilitates maintenance and replacement, while the use of durable materials enhances corrosion and impact resistance, making them suitable for complex terrains and diverse water conservancy needs. The emergence of prefabricated irrigation canals provides a highly efficient, economical, and sustainable solution for modern water conservancy projects.

[0003] In the prior art, a detachable and modular water channel for water conservancy projects, disclosed in publication number "CN221822838U", relates to the technical field of water diversion devices for water conservancy projects. It includes a U-shaped base, with a set of side beams symmetrically installed on the upper end of the U-shaped base. A connecting frame is fixedly installed above one end of each side beam. A set of U-shaped water-blocking components are symmetrically installed in the middle of the connecting frame. One side of each U-shaped water-blocking component is attached to the end of the side beam. A rubber elastic element is fixedly installed in the middle of each U-shaped water-blocking component. A set of bolts is symmetrically installed on the upper end of the connecting frame. Arc-shaped frames are fixedly installed on both sides of the side beam. A set of fixing frames is symmetrically installed at both ends of the arc-shaped frames, with one side of each fixing frame attached to the surface of the side beam. This utility model, by setting up connecting frames, fixing frames, and fixing studs, can achieve rapid connection of multiple U-shaped bases and side beams, which not only improves the stability of the device but also avoids leakage or breakage during long-term use, greatly reducing the difficulty of installation and maintenance.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Traditional water channel connections in existing technologies require complex tools and cumbersome procedures. For example, the use of numerous bolts and nuts for tightening requires not only skilled construction workers but also a significant amount of time. Furthermore, traditional disassembly-based water channel connections often fail to achieve a good seal, allowing water to easily leak from the joints. This not only wastes water resources but may also impact the surrounding environment. Utility Model Content

[0006] The purpose of this invention is to provide a detachable, modular water channel for water conservancy projects, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A detachable and modular water channel for water conservancy projects includes a water channel body. One end of the water channel body is provided with a splicing groove, which includes a straight groove and an expansion groove. The other end of the water channel body is fixedly provided with a splicing block that matches the splicing groove. The splicing block includes a fixing part and an expansion part.

[0009] The water channel body has several grooves. An expansion component is fixedly installed in the groove on one side of the splicing block. The expansion component is provided with a buckle. A movable buckle is fixedly installed in the groove on one side of the splicing groove. Through the cooperation of the movable buckle and the buckle, the expansion component can be driven to move, thereby causing the expansion part to tighten in the expansion groove.

[0010] Preferably, the expansion assembly includes a piston cylinder fixedly disposed in the groove, a piston rod slidably disposed in the piston cylinder, a return spring sleeved on the piston rod, and one end of the piston rod being fixedly connected to a buckle;

[0011] The piston cylinder is fixedly connected to the expansion section of the splicing block via a pipe; the piston cylinder and the expansion section are filled with an expansion medium.

[0012] Preferably, several buckles and movable fasteners are also fixedly provided on the side wall of the water channel body.

[0013] Preferably, the movable buckle has a through groove, the water channel body is fixedly provided with a fixing plate, and a locking piece is rotatably provided on the fixing plate.

[0014] Preferably, the water channel body is provided with a support section, and the support section is provided with a cover plate.

[0015] Preferably, the cover plate has several filter grooves.

[0016] Preferably, a number of positioning plates are fixedly provided on the water channel body, and a number of positioning grooves that match the positioning plates are fixedly provided on the cover plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The design of the movable buckle greatly simplifies the assembly process of the water channel body. Traditional water channel connections may require complex tools and cumbersome operating procedures, while this device only requires rotating the movable buckle to fit onto the clip, quickly completing the initial connection of two water channel bodies. This makes the assembly of the water channel simpler and faster, reducing construction time and labor costs, and is especially suitable for large-scale water conservancy projects, effectively improving construction efficiency.

[0019] 2. The movable buckle directly connects the two water channel bodies together on the one hand, and on the other hand, by pulling the buckle, it drives the expansion component to tighten the splicing block in the splicing groove, thus achieving a double connection guarantee.

[0020] When the movable latch drives the expansion assembly, the expansion section expands under the pressure of hydraulic oil, tightly fitting against the inner wall of the expansion groove. This tight fit creates a good seal, effectively preventing water leakage from the joint. Compared to traditional water channel connections, this significantly improves waterproofing performance.

[0021] 3. When repairs, modifications, or relocations of the irrigation canal are required, simply reverse the movable latch to detach it from the clip, and the two canal bodies can be easily separated. This detachable design makes maintenance and modifications of the irrigation canal easier, without damaging the entire canal structure, reducing maintenance costs and environmental impact.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the field of water conservancy engineering, a detachable, modular water channel has been designed to facilitate the installation, disassembly, and maintenance of water canals. The following will detail the specific structure, connection relationships, and working principles of each component of this water channel.

[0032] Please see Figure 1-7 This utility model provides a technical solution:

[0033] Example 1:

[0034] A detachable, modular water channel for water conservancy projects, the main body of which is the water channel body 1. The water channel body 1 is generally V-shaped and long, and is made of high-strength, corrosion-resistant engineering plastics or concrete to adapt to the complex environment of water conservancy projects.

[0035] One end of the water channel body 1 is provided with a splicing groove 11, such as Figure 6 As shown, the splicing groove 11 is composed of a straight groove 111 and an expansion groove 112. The straight groove 111 is located on the outside of the splicing groove 11, and its shape is a regular rectangle. Its width and depth are designed according to the dimensions of the water channel body 1, and it is mainly used for the initial positioning of the fixing part 121 of the splicing block 12. The expansion groove 112 is located on the inside of the straight groove 111, and its cross-sectional dimensions are larger than those of the straight groove 111, providing expansion space for the expansion part 122.

[0036] At the other end of the water channel body 1, a splicing block 12 matching the splicing groove 11 is fixedly installed. The splicing block 12 consists of a fixing part 121 and an expansion part 122. The fixing part 121 is a rectangular block structure, the size of which fits tightly with the straight groove 111, allowing it to be accurately inserted into the straight groove 111 during splicing. The expansion part 122 surrounds the outside of the fixing part 121 and is made of elastic rubber or silicone material, possessing good elasticity and sealing properties, and can expand under pressure.

[0037] During the assembly of the irrigation canals, the splicing block 12 of one irrigation canal body 1 is aligned with the splicing groove 11 of another irrigation canal body 1, so that the splicing block 12 is inserted into the splicing groove 11. At this time, the splicing block 12 and the splicing groove 11 are initially connected, but the connection is not tight.

[0038] The water channel body 1 has several grooves 13, which are distributed on one side of the splicing block 12 and the splicing groove 11. An expansion component 2 is fixedly installed in the groove 13 on one side of the splicing block 12. The expansion component 2 is mainly composed of components such as piston cylinder 22, piston rod 23, return spring 24, and pipe 25.

[0039] The piston cylinder 22 is fixed in the groove 13 by bolts or welding. Its interior is a cavity to accommodate the piston rod 23 and the expansion medium. The piston rod 23 is slidably disposed within the piston cylinder 22, enabling linear reciprocating motion within the cylinder. A return spring 24 is fitted onto the piston rod 23. One end of the return spring 24 is fixedly connected to the inner wall of the piston cylinder 22, and the other end is fixedly connected to a boss on the piston rod 23. One end of the piston rod 23 extends out of the piston cylinder 22 and is fixedly connected to a snap-fit ​​21.

[0040] The piston cylinder 22 is fixedly connected to the expansion section 122 of the splicing block 12 via a pipe 25. The pipe 25 is made of high-strength, high-pressure resistant rubber or metal tubing to ensure the sealing and reliability of the connection. The piston cylinder 22 and the expansion section 122 are filled with an expansion medium, which can be hydraulic oil or other liquids; hydraulic oil is used as an example here.

[0041] A movable buckle 3 is fixedly installed in the groove 13 on one side of the splicing groove 11.

[0042] After the splicing block 12 is inserted into the splicing slot 11, the movable latch 3 is rotated so that it fits onto the buckle 21. As the movable latch 3 rotates further, it pulls the buckle 21, which in turn causes the piston rod 23 to slide within the piston cylinder 22. Due to the sliding of the piston rod 23, the hydraulic oil in the piston cylinder 22 is compressed and forced into the expansion section 122 through the pipe 25.

[0043] After the hydraulic oil enters the expansion section 122, the expansion section 122, made of elastic material, begins to expand under the pressure of the hydraulic oil, filling the space of the expansion groove 112. As the expansion section 122 continues to expand, it fits tightly against the inner wall of the expansion groove 112, thereby tightening the splicing block 12 in the splicing groove 11, achieving a tight connection between the two water channel bodies 1, and effectively preventing water leakage.

[0044] When it is necessary to disassemble the water channel, rotate the movable latch 3 in the opposite direction to separate it from the buckle 21. At this time, under the action of the return spring 24, the piston rod 23 returns to the initial position, the pressure in the piston cylinder 22 decreases, the hydraulic oil in the expansion part 122 flows back into the piston cylinder 22, the expansion part 122 contracts, the connection between the splicing block 12 and the splicing groove 11 becomes loose, and the two water channel bodies 1 can be easily separated.

[0045] Example 2:

[0046] To further enhance the stability of the water channel after splicing, several clips 21 and movable fasteners 3 are also fixedly installed on the side wall of the water channel body 1. The structure of these clips 21 and movable fasteners 3 is the same as that at the splicing point. When splicing multiple water channel bodies 1, they are connected not only by splicing blocks 12 and splicing grooves 11, but also by the clips 21 and movable fasteners 3 on the side wall, so that the water channel forms a whole and improves its stability under the impact of water flow.

[0047] The movable buckle 3 has a through groove 31, and a fixing plate 4 is fixedly installed on the water channel body 1. The fixing plate 4 is fixed to the surface of the water channel body 1 by bolts. A locking piece 41 is rotatably installed on the fixing plate 4. The locking piece 41 is connected to the fixing plate 4 by a pin and can rotate around the pin.

[0048] Once the movable latch 3 and the buckle 21 are in place, rotate the locking piece 41 so that it covers the through groove 31 of the movable latch 3, preventing the movable latch 3 from accidentally rotating and separating from the buckle 21, thereby further enhancing the connection stability at the splice.

[0049] Example 3:

[0050] The water channel body 1 is provided with a support section 14, which is a platform structure with an inwardly recessed top of the water channel body 1. Its surface is flat and it is used to place the cover plate 5. The cover plate 5 is made of high-strength plastic or metal plate, which has a certain strength and rigidity and can withstand a certain weight and external impact.

[0051] The cover plate 5 has several filter grooves 51, which are evenly distributed on the cover plate 5 in the form of strips or circles. The function of the filter grooves 51 is to filter impurities in the water and prevent larger impurities from entering the water channel, affecting the normal flow of water and the service life of the water channel.

[0052] Several positioning pieces 15 are fixedly installed on the main body 1 of the water channel. The positioning pieces 15 are raised block structures and are integrally formed. Several positioning grooves 52 that match the positioning pieces 15 are fixedly installed on the cover plate 5. The positioning grooves 52 are recessed groove structures. When installing the cover plate 5, the positioning grooves 52 are aligned with the positioning pieces 15 so that the cover plate 5 is accurately placed on the mounting part 14, ensuring the accuracy and stability of the cover plate 5 installation.

[0053] Working principle: In the process of using this utility model, when splicing water channels, the splicing block 12 of one water channel body 1 is aligned with the splicing groove 11 of another water channel body 1, so that the fixing part 121 is inserted into the straight groove 111 to complete the initial positioning and connection, but the connection is not tight at this time.

[0054] After the splicing block 12 is inserted into the splicing groove 11, rotate the movable buckle 3 located in the groove 13 on one side of the splicing groove 11 so that it is put on the buckle 21 connected to the piston rod 23.

[0055] As the movable latch 3 rotates further, it pulls the buckle 21, which in turn causes the piston rod 23 to slide within the piston cylinder 22. Due to the sliding of the piston rod 23, the hydraulic oil within the piston cylinder 22 is compressed.

[0056] The squeezed hydraulic oil is forced into the expansion section 122 through the pipe 25. Because the expansion section 122 is made of elastic rubber or silicone material, it begins to expand under the pressure of the hydraulic oil, filling the space of the expansion groove 112. As the expansion section 122 continues to expand, it fits tightly against the inner wall of the expansion groove 112, causing the splicing block 12 to tighten in the splicing groove 11, achieving a tight connection between the two water channel bodies 1 and effectively preventing water leakage.

[0057] When the movable latch 3 is pulled to the limit position by the latch 21, continue to press the movable latch 3, as shown. Figure 7 Once the movable buckle 3 reaches its limit position, rotate the locking piece 41 to position the movable buckle 3.

[0058] When it is necessary to disassemble the water channel, rotate the movable latch 3 in the reverse direction to separate it from the clip 21. For example... Figure 6 As shown, at this time, under the action of the return spring 24, the piston rod 23 returns to the initial position, the pressure in the piston cylinder 22 decreases, the hydraulic oil in the expansion part 122 flows back into the piston cylinder 22, the expansion part 122 contracts, the connection between the splicing block 12 and the splicing groove 11 becomes loose, and the two water channel bodies 1 can be easily separated.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
