Description

Technical Field

[0001] This utility model relates to the field of river water diversion technology, and in particular to a short-segment river water diversion device for water conservancy construction. Background Technology

[0002] Water flow control during hydraulic construction, commonly known as construction diversion, aims to create necessary construction conditions and meet the water usage requirements of various departments by safely diverting or impounding part or all of the incoming water from the original river at different times and locations according to a predetermined method. Diversion construction technology is a measure in hydraulic engineering that directly impacts 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 begins, using cofferdams to protect the foundation pit. Construction diversion plays a particularly important role in dam and gate construction projects.

[0003] In water conservancy construction, appropriate diversion equipment is usually required. However, in practical applications, existing diversion devices often lack effective filtration mechanisms in the river water diversion connecting pipes, resulting in the inability to remove aquatic plants and other impurities in a timely manner. When aquatic plants and other impurities accumulate inside the connecting pipes, it may cause partial blockage of the diversion device. At the same time, the existing diversion devices, due to the inflexible adjustment of the connection length of their connecting pipes, may be limited by the distance between the water conservancy project and a small section of the river, thus affecting construction efficiency and adaptability.

[0004] Based on this, we propose a short-segment river water diversion device for hydraulic construction to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a short-segment river water diversion device for water conservancy construction, which can solve the problems of impurity accumulation and non-adjustable connection pipe length caused by the lack of an effective filtration mechanism in the existing diversion equipment, thus affecting construction efficiency and adaptability.

[0007] To solve the above-mentioned technical problems, this utility model provides a short-segment river water diversion device for water conservancy construction, which adopts the following technical solution: it includes a diversion pipe body, and diversion ends are respectively installed at both ends of the diversion pipe body. The diversion end includes a connecting pipe body, and a flow guide cover is provided at the end of the connecting pipe body away from the diversion pipe body. A sealing cover is hinged to the top of the connecting pipe body, and an impurity filter is also installed inside the connecting pipe body.

[0008] The impurity filter includes a first filter component, and a second filter component is disposed inside the first filter component.

[0009] Optionally, the connecting pipe body has a flow guiding cavity inside, and two sets of positioning frames are installed on both sides of the flow guiding cavity. A positioning groove is also provided in the middle of one side of the positioning frame.

[0010] Optionally, the first filter assembly includes a support frame, an embedding groove is provided through the middle of the support frame, a limiting groove is provided on both sides of the embedding groove, an impurity filter screen is provided on both sides of the support frame, and a positioning plate is provided on both sides of the support frame near the impurity filter screen.

[0011] Optionally, the positioning plate and the positioning groove are matched, and the positioning plate and the positioning groove are interlocked.

[0012] Optionally, the second filter assembly includes a filter element that matches the embedded groove structure. Two sets of limiting plates are respectively installed at both ends of the filter element, and the limiting plates and the limiting groove are engaged in a snap-fit ​​relationship.

[0013] Optionally, the drainage tube body and one end of one set of connecting tubes are each connected to a U-shaped insert plate, and the drainage tube body and one end of the other set of connecting tubes are respectively provided with U-shaped slots. The U-shaped slots and U-shaped insert plates are structurally matched, and the U-shaped slots and U-shaped insert plates are in a transition fit.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution forms a complete flow guiding device by adding flow guiding heads to both ends of the flow guiding pipe. The flow guiding head mainly consists of a connecting pipe, a flow guiding cover, a sealing cover, and an impurity filter. The impurity filter includes a first filter component and a second filter component. The first filter component can stably connect the support frame to the inside of the connecting pipe through the insertion and engagement of the positioning plate and the positioning groove, as well as the snap-fit ​​engagement of the limiting plate and the limiting groove. At the same time, the filter element can be snapped into the inside of the support frame. Through the impurity filter screens on both sides of the support frame and the internal filter element, the river water can be filtered multiple times to prevent impurities such as aquatic plants from entering the flow guiding device, thereby avoiding blockage.

[0016] 2. This solution incorporates a U-shaped insert plate and a U-shaped slot between the diversion pipe and the connecting pipe. The U-shaped slot matches the structure of the U-shaped insert plate, and the two are in a transitional fit. This design allows multiple diversion pipes to be effectively spliced ​​together. At the same time, the diversion end for filtration can also be installed at both ends of the spliced ​​diversion pipe. Through the above structural design, the diversion device of this solution can flexibly adjust the overall splicing length of the diversion pipe according to the actual distance between the water conservancy project and the small section of the river, thereby enhancing the adaptability and practicality of the equipment during use.

This diversion device, through the impurity filter screens 15 installed on both sides of the support frame 12 and the filter core 17 installed inside, can perform multiple filtration treatments on the river water diverted inside, which can prevent impurities such as aquatic plants in the river water from entering the interior of the diversion device and avoid clogging during use.

[0028] The connecting pipe body 3 has a flow guiding cavity 9 inside. Two sets of positioning frames 10 are installed on both sides of the flow guiding cavity 9. A positioning groove 11 is also provided in the middle of one side of each positioning frame 10. The first filter assembly 7 can be positioned and connected to the inside of the connecting pipe body 3 through the positioning groove 11 in the middle of one side of the positioning frame 10. The first filter assembly 7 includes a support frame 12. An embedding groove 13 is provided through the middle of the support frame 12. Limiting grooves 14 are provided on both sides of the embedding groove 13. Both sides of the support frame 12 are provided with… The impurity filter screen 15 and the support frame 12 are respectively provided with positioning plates 16 on both sides near the impurity filter screen 15. The second filter component 8 can be snapped into the inside of the support frame 12 by the embedding groove 13 and the limiting groove 14 opened in the middle of the support frame 12. The positioning plate 16 and the positioning groove 11 are structurally matched and are plugged into each other. Through the structural design of the plugged into the positioning plate 16 and the positioning groove 11, the support frame 12 can be limited and connected to the inside of the flow guiding cavity 9.

[0029] The second filter assembly 8 includes a filter element 17, which is structurally matched with the embedded groove 13. Two sets of limiting plates 18 are installed at both ends of the filter element 17. The limiting plates 18 and the limiting groove 14 are engaged. Through the structural design of the engagement between the limiting plates 18 and the limiting groove 14, the filter element 17 can be snapped into the inside of the support frame 12. One end of the drainage pipe body 1 and one set of connecting pipe bodies 3 are connected with a U-shaped insert plate 19. One end of the drainage pipe body 1 and the other set of connecting pipe bodies 3 are also provided with U-shaped slots 20. The U-shaped slots 20 and the U-shaped insert plates 19 are structurally matched. The U-shaped slots 20 and the U-shaped insert plates 19 are transitionally engaged. Through the structural design of the transitional engagement between the U-shaped slots 20 and the U-shaped insert plates 19, multiple sets of drainage pipe bodies 1 can be connected together first, and the drainage end 2 for river water filtration can be assembled at both ends of the multiple sets of drainage pipe bodies 1 that are first spliced ​​together.

Since the U-shaped slot 20 and the U-shaped insert plate 19 are structurally compatible, and the U-shaped slot 20 and the U-shaped insert plate 19 are in transition fit, multiple sets of diversion pipe bodies 1 can be connected together first, and the diversion end 2 used for river water filtration can be assembled at both ends of the multiple sets of diversion pipe bodies 1 that are first spliced ​​together. This allows the diversion device to adjust the overall splicing length of the diversion pipe body 1 according to the distance between the water conservancy project and the small section of the river.
