Description

Technical Field

[0001] This utility model is a diversion device for water conservancy construction, belonging to the field of water conservancy equipment technology. Background Technology

[0002] Water flow control during hydraulic construction, commonly known as construction diversion, aims to create necessary construction conditions and meet the water requirements of various departments by safely diverting or impounding part or all of the inflow from the original river at different times and locations according to a predetermined method, time, and location. Diversion construction technology is a measure in hydraulic engineering that directly affects the construction efficiency and quality. To ensure favorable construction conditions, it is necessary to guide the existing water flow to effectively avoid the construction site before construction, using cofferdams to protect the foundation pit. Construction diversion plays a particularly important role in dam and gate construction projects. Appropriate diversion equipment is required during hydraulic construction.

[0003] Publication number CN220868111U mentions a diversion device for water conservancy construction. In this device, the filter box can be disassembled via a trapezoidal slider, facilitating the centralized cleaning of debris in the water. The filter screen on the filter box can also be removed via a slot, allowing workers to clean the attached impurities on the screen, keeping it clean and ensuring its normal filtration effect. This prevents the screen from becoming clogged due to excessive impurities. However, the filter screen in this device is a single unit, and after prolonged use, it becomes clogged and needs to be removed for cleaning. During this process, subsequent diversion and drainage cannot be used until the filter screen is cleaned and reinstalled, which is time-consuming. There is an urgent need for a diversion device for water conservancy construction to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a water conservancy construction diversion device to solve the problems mentioned in the background. This utility model designs a push-pull combined filter screen structure, which can quickly pull out a single filter screen when it needs cleaning, and at the same time allow the idle filter screen on the other side to be moved into the diversion box for filtration, thus avoiding unnecessary disassembly and assembly time and ensuring the diversion and drainage efficiency in water conservancy construction.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a water conservancy construction diversion device, comprising a diversion box, a first mounting frame, a first filter screen, a second mounting frame, and a second filter screen. A sealing cover is sealed at the upper end of the diversion box, and an opening groove is formed through the side surface of the diversion box. An overflow box is provided at the lower end of the diversion box, and support legs are provided around the lower end of the diversion box. The first mounting frame is installed through the opening groove. Two first filter screens are longitudinally installed on the front and rear sides of the first mounting frame using multiple first hexagonal socket bolts. The second mounting frame is integrally fixed to the right end of the first mounting frame. Two second filter screens are longitudinally installed on the front and rear sides of the second mounting frame using multiple second hexagonal socket bolts, and both first filter screens are located inside the diversion box.

[0006] Furthermore, a bent pipe is installed at the rear end of the flow guide box, and a connecting flange is installed at the upper end of the bent pipe.

[0007] Furthermore, the overflow box is located below the opening slot, and a valved pipe is installed at the front end of the overflow box.

[0008] Furthermore, multiple diversion pipes are installed at the front end of the diversion box, and water-blocking valves are installed at the upper ends of the multiple diversion pipes.

[0009] Furthermore, side handles are provided on the left side of the first mounting frame and the right side of the second mounting frame.

[0010] Furthermore, each of the legs is provided with abrasion-resistant rubber pads at its lower end.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a water conservancy construction diversion device. Because this utility model adds a diversion box, an overflow box, a first mounting frame, a first filter screen, a side handle, a second mounting frame, a second filter screen, a second hexagonal socket head cap screw, and a first hexagonal socket head cap screw, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. The design of a push-pull combined filter screen structure allows for quick pulling out when a single filter screen needs cleaning, while simultaneously allowing the idle filter screen on the other side to be moved into the diversion box for filtration. This avoids wasting unnecessary disassembly and assembly time and ensures the diversion and drainage efficiency in water conservancy construction. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a water conservancy construction diversion device, including a diversion box 2, a first mounting frame 11, a first filter screen 12, a second mounting frame 14, and a second filter screen 15. A sealing cover plate 1 is sealed on the upper end of the diversion box 2. An opening groove 5 is formed through the side surface of the diversion box 2. An overflow box 6 is provided at the lower end of the diversion box 2. Support legs 10 are provided around the lower end of the diversion box 2. The first mounting frame 11 is installed through the opening groove 5. Multiple first mounting frames 11 are connected to the front and rear sides of the first mounting frame 11 via... Two first filter screens 12 are longitudinally installed by a hexagon socket bolt 17. A second mounting frame 14 is integrally fixed to the right end of the first mounting frame 11. Two second filter screens 15 are longitudinally installed on the front and rear sides of the interior of the second mounting frame 14 by multiple second hexagon socket bolts 16. Both first filter screens 12 are located inside the flow guide box 2. This design solves the problem that in the original device, the filter screen is set as a single screen, which needs to be removed and cleaned after long-term use when it becomes clogged, which wastes unnecessary disassembly and assembly time and affects the efficiency of its flow guide and drainage.

[0019] As the first embodiment of this utility model: a bent pipe 3 is installed at the rear end of the flow guide box 2, and a connecting flange 4 is installed at the upper end of the bent pipe 3. The added connecting flange 4 facilitates its connection to an external drainage pipe via bolts. The overflow box 6 is located below the opening slot 5, and a valve-equipped pipe 7 is installed at the front end of the overflow box 6. Through the added overflow box 6, water overflowing from the opening slot 5 can be collected during the movement of the first mounting frame 11 or the second mounting frame 14.

[0020] Multiple diversion pipes 8 are installed at the front end of the diversion box 2, and each of the multiple diversion pipes 8 is equipped with a water-blocking valve 9. The addition of multiple diversion pipes 8 facilitates the diversion of diverted water during water conservancy construction. Side handles 13 are provided on the left side of the first mounting frame 11 and the right side of the second mounting frame 14.

[0021] As a second embodiment of this utility model: In actual use, the connecting flange 4 is connected to the drainage pipe in the external water conservancy construction using bolts. Then, multiple diversion pipes 8 are connected to the external diversion pipe, and the water-blocking valve 9 is opened for diversion. During this process, the two first filter screens 12 will intercept and filter impurities in the diverted water. After long-term use, when the filtration effect is greatly reduced, the water conservancy construction personnel pull the side handle 13 to the left, and the first mounting frame 11 can move to the left in the diversion box 2 through the opening slot 5 until the two first filter screens 12 and the first mounting frame 11 are completely pulled out. During this process, because the second mounting frame 14... The body is fixed to the right end of the first mounting frame 11. When the first mounting frame 11 moves to the left, it will drive the second mounting frame 14 to move into the flow guide box 2 through the right side of the opening slot 5. This will also pull the two second filter screens 15 into the flow guide box 2 for filtration. During this process, the water overflowing through the opening slot 5 will be collected in the overflow box 6 for subsequent treatment by water conservancy construction personnel. Finally, water conservancy construction personnel can use an external hex wrench to unscrew multiple first hex bolts 17 to remove the two first filter screens 12 for cleaning. During this process, the two second filter screens 15 will be used for filtration, ensuring that the flow guide and drainage efficiency during water conservancy construction is not affected.
