Description

Technical Field

[0001] This utility model belongs to the field of river regulation technology, specifically a dam structure for river regulation. Background Technology

[0002] Dikes and dams: a general term for dikes and dams, also referring to structures and buildings that prevent water from entering or being blocked. For example, it is necessary to speed up the construction of dikes and dams to prevent floods. Modern dams are mainly divided into two categories: earth-rock dams and concrete dams. In recent years, large dikes have adopted high-tech reinforced concrete construction.

[0003] For example, utility model publication CN219033083U discloses a dam structure for river regulation, belonging to the field of dam structures. It addresses the technical problem of existing dam structures for river regulation using mud filters to filter liquids in mud. The mud filters are prone to corrosion when soaked in river water, and the fixed installation method affects the replacement of the mud filters during later maintenance. The proposed solution includes a protective shell, with a frame installed on the outer wall of the shell. A mesh plate is fixedly connected inside the frame, an insert plate is fixedly connected to the outer wall of the frame, and a retainer is sleeved on the outer wall of the insert plate. The retainer and the protective shell are fixedly connected. A pin is sleeved inside the insert plate, and the pin and the retainer are sleeved together. A sealing plug is installed on the top of the retainer.

[0004] When using the above-mentioned device, the mud filter screen is connected by a pin and a clip, which allows for quick disassembly and replacement of the mud filter screen. However, when the device is put into use, the mud filter screen needs to be disassembled, cleaned and replaced frequently. This process is troublesome and inefficient. The surface of the mud filter screen needs to be cleaned to ensure that the mud filter screen can operate normally and to prevent rust from forming. Utility Model Content

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a dam structure for river regulation, including a dam fixed base 1, a mud filter screen 2 fixed on the inner wall of the dam fixed base 1, a plurality of filter holes 3 opened on the outer wall of the mud filter screen 2, a movable groove 4 opened on the inner wall of the dam fixed base 1, and a self-cleaning structure 5 provided at one end of the movable groove 4.

[0024] The above scheme is adopted: by fixing two sets of dam fixed bases 1 on both sides of the river, the position of the mud filter screen 2 is facing the water flow position, so that the sludge can be filtered through several sets of filter holes 3 opened on the surface of the mud filter screen 2 and the water source can flow into the next river channel through the filter holes 3.

[0025] like Figures 1 to 5As shown, the self-cleaning structure 5 includes a cleaning strip 501, a reciprocating screw 502, and a first bevel gear 503. The cleaning strip 501 is slidably connected to the inner cavity of the moving groove 4. The front and rear ends of the cleaning strip 501 are threadedly connected to the reciprocating screw 502. The front and rear ends of the cleaning strip 501 are provided with internal threads. The reciprocating screw 502 is rotatably connected to the inside of the dam fixed base 1. The outer wall of the reciprocating screw 502 is provided with reciprocating threads. The cleaning strip 501 and the reciprocating screw 502 form a threaded connection. The outer wall of the reciprocating screw 502 is fixed with the first bevel gear 503. The side end of the first bevel gear 503 is meshed with a second bevel gear 504. The second bevel gear 504 is fixed to the left end of the mounting rod 505. The third bevel gear 506 is fixed to the right end of the mounting rod 505. The second bevel gear 504 and the third bevel gear 506 are symmetrically distributed about the central axis of the mounting rod 505.

[0026] like Figures 1 to 5 As shown, a mounting rod 505 is fixed to the side end of the second bevel gear 504, a third bevel gear 506 is fixed to the side end of the mounting rod 505, a fourth bevel gear 507 is meshed with the front end of the third bevel gear 506, a fixing rod 508 is fixed to the front end of the fourth bevel gear 507, and a transmission paddle 509 is fixed at equal intervals on the outer wall of the fixing rod 508. The transmission paddles 509 are fixed on the outer wall of the fixing rod 508 and are distributed at equal intervals about the central axis of the fixing rod 508.

[0027] The above scheme utilizes the power applied to the propeller 509 by the flowing water in the river, causing the propeller 509 to rotate the fixed rod 508 about its central axis. This rotation of the fixed rod 508 then drives the fourth bevel gear 507 mounted at both ends to rotate. Due to the meshing design between the fourth bevel gear 507 and the third bevel gear 506, the rotation of the fourth bevel gear 507 also drives the third bevel gear 506 to rotate. This rotation of the third bevel gear 506, in turn, drives the fixed mounting rod 505 and the second bevel gear 504 fixed to the other side wall of the mounting rod 505. Rotation: Since the second bevel gear 504 and the first bevel gear 503 are meshed, the second bevel gear 504 can drive the first bevel gear 503 to rotate when it rotates, thereby driving the reciprocating screw 502 to rotate through the first bevel gear 503. Since the outer wall of the reciprocating screw 502 is provided with reciprocating threads, it can cooperate with the screw holes opened on the front and rear sides of the cleaning strip 501. When the reciprocating screw 502 rotates, it drives the cleaning strip 501 to move up and down reciprocally, so that the cleaning strip 501 can continuously contact the side of the mud filter screen 2 that filters sludge and clean it, which can effectively prevent the accumulation of mud and rust on the surface of the mud filter screen 2.

[0028] like Figures 1 to 5As shown, the outer wall of the fixed bottom 1 of the dam is provided with a pressure relief groove 6, the inner wall of the fixed bottom 1 of the dam is fixed with a corrosion-resistant layer 7, the front wall of the corrosion-resistant layer 7 is installed with a seepage-proof layer 8, the front wall of the seepage-proof layer 8 is installed with a pressure-increasing layer 9, the front wall of the pressure-increasing layer 9 is provided with a crack-resistant layer 10, the fixed bottom 1 of the dam is provided with two sets of symmetrically distributed about the central axis of the mud filter screen 2, and the pressure relief groove 6 is provided with several sets of equally spaced grooves on the outer wall of the fixed bottom 1 of the dam.

[0029] The above solution involves: providing a pressure relief groove 6 on the side wall of the fixed bottom 1 of the dam; the pressure relief groove 6 can prevent the device from being damaged by excessive water pressure impact; and by fixing a corrosion-resistant layer 7, a seepage-proof layer 8, a pressure-increasing layer 9, and a crack-resistant layer 10 on the inner wall of the fixed bottom 1 of the dam, the overall corrosion resistance, seepage prevention, overall strength, and crack resistance of the fixed bottom 1 of the dam can be significantly improved, thereby extending the overall service life of the device and ensuring its normal operation.

[0030] The working principle and usage of this utility model are as follows: By fixing two sets of dam fixed bases 1 on both sides of the river channel, the mud filter screen 2 is positioned directly opposite the water flow. The mud filter screen 2, through several sets of filter holes 3 on its surface, filters out the sludge and allows water to flow through these holes into the next river channel. The mud filter screen 2, installed between the two sets of dam fixed bases 1, filters out the sludge in the water, allowing clean water to flow to the rear end of the mud filter screen 2. As the water flows in the river, it drives the transmission paddle 509, which in turn drives the fixed rod 508. The rotation of the fixed rod 508 causes the third bevel gear 506 to rotate via the fourth bevel gear 507. This rotation of the third bevel gear 506 causes the mounting rod 505 and the second bevel gear 504 to rotate, which in turn causes the first bevel gear 503 to rotate, ensuring that the reciprocating screw 502 can rotate. When the reciprocating screw 502 rotates, the cleaning strip 501 can reciprocate on the reciprocating screw 502 via the thread on its outer wall, thus enabling the cleaning strip 501 to clean the surface of the mud filter screen 2 during lifting and lowering.
