Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and in particular to flood discharge equipment for water conservancy projects. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. Water conservancy projects are projects built to eliminate water disasters and develop and utilize water resources. Water conservancy projects that can serve multiple goals such as flood control, water supply, irrigation, and power generation are called comprehensive water conservancy projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals.

[0003] After searching, the existing patent (Announcement No.: CN220246840U) discloses a flood discharge equipment for water conservancy projects, including a flood discharge base and a gantry, the gantry is fixed to the upper end of the flood discharge base, the front and rear parts of the left and right ends inside the flood discharge base are fixed with guide rails, a gate is arranged between the guide rails, the left and right sides of the front and rear ends of the gate are rotatably connected with a plurality of pulleys, the pulleys are matched in the guide rails, and the left and right ends of the gate are provided with a pressure relief sealing assembly and a sliding drive assembly; the utility model reduces the friction resistance encountered by the gate when it is opened, and through the rotation of the pulley in the guide rail, compared with the prior art, the sliding friction encountered by the gate is improved to rolling friction with smaller friction force, thereby making the opening of the gate easier and more labor-saving, and the opening process is smoother, so as to avoid the situation that the gate is not opened in time, which is conducive to timely and normal flood discharge operations.

[0004] However, in the implementation of the relevant technology, it was found that the above-mentioned problems exist: in the above-mentioned, the left and right sides of the front and rear ends of the gate are rotatably connected with a number of pulleys, and the pulleys are matched in the guide rails. In order to enable the pulleys to rotate in the guide rails, it is necessary to avoid the surface of the gate from contacting the guide rails, otherwise it will cause a large pressure between the gate and the guide rails and fail to reduce the frictional resistance of the gate. Therefore, when the pulley is set in the guide rail, it is necessary to make a certain gap between the surface of the gate and the guide rail. However, there will be impurities such as seaweed in the water. These seaweeds will easily enter the guide rails through the gaps, and the seaweed will easily entangle the pulley and make it unable to rotate, which will cause the pulley to fail to play the role of reducing its frictional resistance when the gate is opened.

[0025] First, the two filter nets 5 are respectively arranged on the side of the gate 4 where the water level is higher. When the gate 4 is not opened to discharge flood water, the two filter nets 5 can respectively cover the gaps between the two guide rails 2 and the surface of the gate 4. The two filter nets 5 will respectively isolate the pulleys 3 on the inner walls of the two guide rails 2. The two filter nets 5 will isolate the seaweed or other solid impurities in the water, which can prevent the seaweed and other impurities from entering the guide rails 2 and easily entangle the pulleys 3 so that they cannot roll.

At this time, the cleaning member 7 is driven by the reciprocating lifting mechanism 6 to perform reciprocating lifting motion along the outer surface of the filter 5, and then the cleaning member 7 is driven by the rotating mechanism 8 to rotate, so that the cleaning member 7 rotates simultaneously during the process of reciprocating lifting motion along the outer surface of the filter 5. The cleaning member 7 will clean the seaweed and other impurities attached to the outer surface of the filter 5 to prevent the filter 5 from being blocked.

[0027] Therefore, firstly, by arranging filter nets 5 on one side of the two guide rails 2, impurities such as seaweed in the water can be isolated, so that impurities such as seaweed can be prevented from entering the guide rail 2 and easily entangle the pulley 3 so that it cannot roll, thereby preventing the pulley 3 from being entangled by the seaweed and unable to play the role of reducing its frictional resistance when the gate 4 is opened, thereby solving the problem in the related art that impurities such as seaweed in the water easily entangle the pulley 3 and prevent it from rotating and unable to play the role of reducing its frictional resistance when the gate 4 is opened; secondly, the cleaning member 7 is driven to perform reciprocating lifting motion by the reciprocating lifting mechanism 6, and the cleaning member 7 is driven to rotate by the rotating mechanism 8, so that the cleaning member 7 rotates simultaneously during the process of performing reciprocating lifting motion along the outer surface of the filter net 5, so that the cleaning member 7 can clean the impurities such as seaweed attached to the outer surface of the filter net 5 to prevent the filter net 5 from being blocked.

[0028] See also Figure 2 and Figure 3The reciprocating lifting mechanism 6 includes a first mounting plate 61, which is fixedly connected to the upper end of the flood discharge base 1. A reciprocating cylinder 62 is fixedly connected to the upper surface of the first mounting plate 61, and a cleaning member 7 is arranged at the output end of the reciprocating cylinder 62. By starting the reciprocating cylinder 62, the cleaning member 7 will be driven to perform reciprocating lifting motion.

[0029] See also Figure 2 , Figure 3 and Figure 4 The cleaning member 7 includes a bracket 71, which is fixedly connected to the output end of the reciprocating cylinder 62. The lower end of the bracket 71 is rotatably connected to a cleaning roller 72. A plurality of cleaning brushes 73 are fixedly connected to the outer wall of the cleaning roller 72 at equal intervals and distributed circumferentially. The rotating mechanism 8 is arranged at one end of the cleaning roller 72. Starting the reciprocating cylinder 62 will drive the bracket 71 to perform reciprocating lifting motion. The bracket 71 will drive the cleaning roller 72 and the cleaning brush 73 thereon to perform reciprocating lifting motion. The cleaning roller 72 and the cleaning brush 73 thereon will clean the outer surface of the filter screen 5.

[0030] See also Figure 2 , Figure 3 and Figure 4 The rotating mechanism 8 includes a second mounting plate 81, which is fixedly connected to one side of the flood discharge base 1. A linkage is provided between one end of the second mounting plate 81 and one end of the cleaning roller 72. The linkage includes a gear 82 and a spur rack 83. The gear 82 is fixedly connected to one end of the cleaning roller 72. The outer ring diameter of the gear 82 is larger than the diameter of the cleaning roller 72. The spur rack 83 is fixedly connected to one end of the second mounting plate 81, and the gear 82 is meshed with the spur rack 83. The length of the spur rack 83 is greater than or equal to the height of the filter screen 5.

[0031] The second mounting plate 81 is an L-shaped structure, and a section of the second mounting plate 81 is parallel to the filter screen 5 and fixedly connected to one side of the flood discharge base 1 , and a section of the second mounting plate 81 is perpendicular to the filter screen 5 and fixedly connected to one side of the spur rack 83 .

[0032] When the reciprocating cylinder 62 drives the cleaning roller 72 and the cleaning brush 73 thereon to perform reciprocating lifting motion, the cleaning roller 72 will always engage with the spur rack 83 with the gear 82 to perform reciprocating rolling in the vertical direction. The gear 82 will synchronously drive the cleaning roller 72 to rotate, and the cleaning roller 72 will drive the cleaning brush 73 thereon to rotate. Therefore, when the cleaning roller 72 and the cleaning brush 73 thereon perform reciprocating lifting motion, they will simultaneously rotate. The rotating cleaning roller 72 and the cleaning brush 73 thereon have a better cleaning effect on the filter screen 5.

[0033] The working principle and use process of the utility model are as follows: first, the two filter screens 5 are respectively arranged on the side of the gate 4 with a higher water level.

The two filter screens 5 will isolate the seaweed or other solid impurities in the water, which can prevent the seaweed and other impurities from entering the guide rails 2 and easily entangle the pulley 3 so that it cannot roll; secondly, the seaweed and other impurities separated by the filter screen 5 will partially adhere to the outer surface of the filter screen 5. At this time, the reciprocating cylinder 62 is started, The bracket 71 will drive the cleaning roller 72 and the cleaning brush 73 thereon to perform reciprocating lifting and lowering movements, and the bracket 71 will drive the cleaning roller 72 and the cleaning brush 73 thereon to perform reciprocating lifting and lowering movements. During this process, the cleaning roller 72 will always be meshed with the spur rack 83 with the gear 82 to perform reciprocating rolling in the vertical direction, and the gear 82 will synchronously drive the cleaning roller 72 to rotate, and the cleaning roller 72 will drive the cleaning brush 73 thereon to rotate. Therefore, while the cleaning roller 72 and the cleaning brush 73 thereon perform reciprocating lifting and lowering movements, they will also rotate at the same time, and the rotating cleaning roller 72 and the cleaning brush 73 thereon will clean up impurities such as seaweed attached to the outer surface of the filter screen 5 to prevent the filter screen 5 from being blocked.
