Description

Technical Field

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

[0002] Water conservancy projects mainly involve surveying, planning, designing, construction, scientific research, and management related to the geographical environment; construction diversion is the process of diverting water to a predetermined spillway structure to discharge water downstream in order to ensure that hydraulic structures can be constructed on dry land during the construction of water conservancy and hydropower projects.

[0003] Referring to the patent with publication number CN221681732U, the disclosed water diversion device for water conservancy construction features a scraping mechanism. The rotating motor on this mechanism drives the scraper to rotate via a rotating shaft, scraping and cleaning the surface of the filter screen. This effectively prevents the filter screen from becoming clogged and affecting normal filtration. At the same time, the booster impeller rotates under the drive of the rotating motor, which can boost the pressure of the water in the diversion box and effectively improve the diversion speed of the water diversion device for water conservancy construction.

[0004] However, this diversion equipment for water conservancy construction still has shortcomings: the water body diverted during water conservancy construction often contains various impurities such as silt, stones, and weeds. The filter screen intercepts these impurities for a long time, and even with a scraping mechanism for cleaning, it is inevitable that the filter screen will wear out, the aperture will deform, or there will be local damage. At this time, it is necessary to disassemble and replace it in time to ensure the filtration effect. However, the diversion box of this equipment is an integrated structure, and the filter screen is fixedly installed inside the diversion box. When it is necessary to disassemble and replace the filter screen, the operation is inconvenient and not quick enough, and its practicality is poor. Utility Model Content

[0005] In view of the existing publicly available water conservancy construction diversion equipment, which has the problem that the diversion box is an integral structure and the filter cover is fixedly installed, making it inconvenient to quickly disassemble and replace the filter cover when it wears out after long-term use, thus affecting the filtration effect, this utility model is proposed.

[0007] The fixing mechanism includes a fixing cover, which is fixedly installed at one end of the end cap and sleeved on the outside of the water outlet. Several connecting blocks are symmetrically arranged on the outside of the fixing cover, and one end of the connecting block is fixedly connected to the flow guide box. The side wall of the end cap is symmetrically provided with limiting grooves that are adapted to the connecting blocks.

[0008] As a preferred embodiment, the fixing mechanism further includes a rotating cylinder, which is rotatably sleeved on the outside of the water outlet and located inside the fixing cover. The inner wall of the rotating cylinder has a driving cavity, and a torsion spring is sleeved on the outside of the water outlet within the driving cavity. The two ends of the torsion spring are fixedly connected to the water outlet and the rotating cylinder, respectively. Several support rods are symmetrically arranged on the outer wall of the rotating cylinder. An insertion rod is hinged to the end of the support rod away from the rotating cylinder through a connecting rod. A through groove adapted to the insertion rod is opened on the side wall of the connecting block. Several operating rods are symmetrically arranged on the outer wall of one end of the rotating cylinder outside the fixing cover.

[0009] As a preferred embodiment, the rotating drum is rotatably connected to the water outlet via a bearing, and the end cover is symmetrically provided with several guide rails on the side wall near the fixed cover. The insertion rod is provided with a guide groove adapted to the guide rails on the side wall near the end cover, and the cross section of the guide rail is an isosceles trapezoid.

[0010] As a preferred embodiment, the end cap is a convex columnar structure, and a sealing ring is provided at the connection between the end cap and the flow guide box. A connecting ring is fixedly connected to the side of the end cap near the filter cover, and the inner wall of the filter cover is threadedly connected to the outer wall of the connecting ring.

[0011] As a preferred embodiment, the cleaning mechanism includes a hollow shaft, which is rotatably mounted inside a guide box at the end away from the end cover. A dual-shaft hollow motor connected to the hollow shaft is fixedly mounted at one end of the guide box, and a rotary joint is connected to the output end of the dual-shaft hollow motor on the side away from the hollow shaft. Several booster impellers are sleeved on the outer side of the hollow shaft. A docking column is provided on the inner side of the filter cover, and one end of the docking column is rotatably connected to the end cover through a support frame. One end of the docking column penetrates the filter cover and is docked to one end of the hollow shaft through a symmetrical assembly. Water spray pipes and scrapers are symmetrically provided on the outer wall of the docking column, and the water spray pipes and scrapers are located on the inner and outer sides of the filter cover, respectively.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-7 As shown, a diversion device for water conservancy construction is provided, including a diversion box 1, an inlet 2 at the top of the diversion box 1, an end cap 4 detachably connected to one end of the diversion box 1, and the end cap 4 is connected to the diversion box 1 by a fixing mechanism. A filter cover 8 is detachably connected to one end of the end cap 4 inside the diversion box 1, and an outlet 5 is connected to one end of the end cap 4. A cleaning mechanism for cleaning the filter cover 8 is provided inside the diversion box 1. A drain outlet 3 with a valve is provided at the bottom of the diversion box 1. A collection box 7 is provided below the drain outlet 3, and a movable base 6 is provided at the bottom of the collection box 7. By detachably connecting the end cap 4 to the diversion box 1, and combining the detachable design of the filter cover 8 and the end cap 4, a basic structure is provided for the disassembly and replacement of the filter cover 8, solving the problem of difficult replacement of the filter cover 8 in traditional equipment with fixed installation, and facilitating later maintenance.

[0029] The fixing mechanism includes a fixing cover 11, which is fixedly installed on one end of the end cap 4 and sleeved on the outside of the outlet 5. Several connecting blocks 12 are symmetrically arranged on the outside of the fixing cover 11, and one end of the connecting block 12 is fixedly connected to the flow guide box 1. The side wall of the end cap 4 is symmetrically provided with limiting grooves 10 that are adapted to the connecting blocks 12. Through the adaptation of the connecting blocks 12 and the limiting grooves 10, the connection between the end cap 4 and the flow guide box 1 is initially positioned, ensuring the accuracy during installation, avoiding misalignment from affecting the subsequent fixing effect, and improving the connection stability.

[0030] In this example, the fixing mechanism also includes a rotating cylinder 13, which is rotatably sleeved on the outside of the outlet 5 and located inside the fixing cover 11. A driving cavity is opened on the inner wall of the rotating cylinder 13. A torsion spring 17 is sleeved on the outside of the outlet 5 inside the driving cavity, and the two ends of the torsion spring 17 are fixedly connected to the outlet 5 and the rotating cylinder 13 respectively. Several support rods 14 are symmetrically arranged on the outer wall of the rotating cylinder 13. The end of the support rod 14 away from the rotating cylinder 13 is hinged to the insertion rod 16 through the connecting rod 15. A through groove adapted to the insertion rod 16 is opened on the side wall of the connecting block 12. Several operating rods are symmetrically arranged on the outer wall of one end of the rotating cylinder 13 outside the fixing cover 11. With the help of the elastic restoring force of the torsion spring 17, and in conjunction with the linkage of the rotating cylinder 13, the support rod 14, the connecting rod 15 and the insertion rod 16, the end cover 4 and the guide box 1 can be quickly fixed and disassembled. The operation only needs to be driven by the operating rod, without the need for complicated tools, which greatly improves the maintenance efficiency.

[0031] In this example, the rotating drum 13 is rotatably connected to the outlet 5 via bearings. Several guide rails 18 are symmetrically arranged on the side wall of the end cover 4 near the fixed cover 11. The insertion rod 16 is provided with a guide groove 19 that matches the guide rail 18 on the side wall of the end cover 4. The cross section of the guide rail 18 is an isosceles trapezoid. The bearing connection ensures that the rotating drum 13 rotates smoothly. The guide rail 18 with the cross section of an isosceles trapezoid cooperates with the guide groove 19 to limit the movement direction of the insertion rod 16, prevent it from deviating, and ensure that the insertion rod 16 is accurately inserted into the through groove of the connecting block 12, thereby improving the stability of the fixing mechanism.

[0032] In this example, the end cap 4 is a convex columnar structure, and a sealing ring is provided at the connection between the end cap 4 and the flow guide box 1. A connecting ring 9 is fixedly connected to the side of the end cap 4 near the filter cover 8, and the inner wall of the filter cover 8 is threadedly connected to the outer wall of the connecting ring 9. The convex structure enhances the fit between the end cap 4 and the flow guide box 1, and the sealing ring ensures that the connection is sealed and leak-proof. The threaded connection makes the filter cover 8 removable and replaceable, further simplifying the maintenance process.

[0033] In this example, the cleaning mechanism includes a hollow shaft 21, which is rotatably mounted inside the guide box 1 at the end away from the end cover 4. A dual-shaft hollow motor 20 connected to the hollow shaft 21 is fixedly mounted at one end of the guide box 1, and a rotary joint is connected to the output end of the dual-shaft hollow motor 20 on the side away from the hollow shaft 21. Several booster impellers 22 are sleeved on the outside of the hollow shaft 21. A docking post 23 is provided inside the filter cover 8, and one end of the docking post 23 is rotatably connected to the end cover 4 through a support frame. One end of the docking post 23 penetrates the filter cover 8 and is connected to the hollow shaft 21 through a symmetrical assembly. The filter cover 8 is connected by a docking column 23. The outer wall of the docking column 23 is symmetrically provided with a water spray pipe 24 and a scraper 25, and the water spray pipe 24 and the scraper 25 are located on the inner and outer sides of the filter cover 8, respectively. The docking column 23 is a hollow structure connected to the hollow shaft 21. The dual-shaft hollow motor 20 drives the hollow shaft 21 and the docking column 23 to rotate, and the booster impeller 22 increases the flow rate. The water spray pipe 24 and the scraper 25 work together to rinse and scrape the filter cover 8 from the inner and outer sides, making the cleaning more thorough and effectively preventing clogging. At the same time, the docking design does not affect the disassembly of the end cover 4, taking into account both cleaning function and maintenance convenience.

[0034] In this example, the docking assembly includes a docking block 28, which is fixedly connected to the docking column 23 through one end of the filter cover 8. A transmission block 27 is connected to the end of the docking block 28 away from the docking column 23. Both the transmission block 27 and the docking block 28 are hollow structures. A docking seat 26 is fitted on the outside of the combined structure of the transmission block 27 and the docking block 28, and the docking seat 26 is fixedly installed inside the hollow shaft 21. The hollow structure of the transmission block 27, the docking block 28 and the docking seat 26 cooperate to realize the power transmission to drive the docking column 23 to rotate, and also ensure that the water flow from the dual-shaft hollow motor 20 through the hollow shaft 21 and the docking column 23 into the spray pipe 24. The structure is compact and does not affect the separation when the end cover 4 is disassembled, ensuring that the cleaning mechanism works continuously and efficiently.

[0035] During operation, water flows into the guide box 1 from the inlet 2. The dual-shaft hollow motor 20 starts, driving the hollow shaft 21 and the docking column 23 to rotate. The booster impeller 22 on the hollow shaft 21 rotates to generate thrust, accelerating the water flow towards the outlet 5. At the same time, water can be supplied periodically to the hollow part of the dual-shaft hollow motor 20 through the rotating joint via an external water supply device. The water flows through the hollow shaft 21 and the docking assembly into the docking column 23, and finally sprays out from the spray pipe 24. Together with the scraper 25, the inside and outside of the filter cover 8 are rinsed and scraped, and the intercepted impurities are deposited at the bottom of the guide box 1.

[0036] When it is necessary to clean up impurities, open the valve of drain outlet 3. The impurities will flow into the collection box 7 with the water flow. After completion, close the valve.

[0037] If the filter cover 8 needs to be replaced, rotate the rotating drum 13 by operating the lever. The torsion spring 17 is twisted, and the rotating drum 13 drives the support rod 14 and the connecting rod 15, so that the insertion rod 16 slides out of the through groove of the connecting block 12 along the guide rail 18. This releases the end cover 4 from the flow guide box 1. After removing the end cover 4, twist the filter cover 8 to separate it from the connecting ring 9, and then replace it with a new filter cover 8. During installation, the operation is reversed. The torsion spring 17 resets and drives the insertion rod 16 to insert into the through groove to complete the fixing.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
