Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a trash rack cleaning device for water conservancy projects. Background Art

[0002] Water conservancy projects are engineering activities aimed at managing, controlling, regulating and utilizing surface and groundwater resources to meet the various needs of human society, including drinking water, irrigation, flood control, power generation, shipping, industrial water supply, environmental restoration and ecological maintenance.

[0003] However, the prior art has the following disadvantages when used: the trash rack is used to prevent floating free objects in the water flow, such as water plants, branches, leaves, garbage, driftwood and other debris from entering important facilities. The debris accumulates on one side of the trash rack, which can easily cause clogging of the trash rack. The existing cleaning device cleans the debris on the surface of the trash rack through a structure such as a scraper, but the scraper will also have debris attached to the surface when cleaning the debris, causing the debris on the surface of the scraper to float in the water when the scraper enters the water and drift to the trash rack again with the water flow, which is not conducive to improving the cleaning effect. Therefore, there is an urgent need for a trash rack cleaning device for water conservancy projects to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that in the prior art, the trash rack is used to prevent floating free objects in the water flow, such as water plants, branches, leaves, garbage, driftwood and other debris from entering important facilities. The debris accumulates on one side of the trash rack, which is easy to cause clogging of the trash rack. The existing cleaning device cleans the debris on the surface of the trash rack through a structure such as a scraper, but the scraper will also have debris attached to the surface when cleaning the debris, resulting in the debris on the surface of the scraper floating in the water when entering the water, and then drifting to the trash rack with the water flow again, which is not conducive to improving the cleaning effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a trash rack cleaning device for water conservancy projects, comprising: a base, one end of which is provided with a fixing frame, and further comprising:

[0006] The trash rack body is arranged on the inner circle of the fixed frame, and two moving blocks are slidably arranged on one end of the fixed frame away from the base;

[0021] The technical effect of adopting the above further scheme is: when the moving block threadably mounted on the reciprocating screw moves, it drives the scraper fixed thereto to move, and the scraper drives one of the moving blocks fixed thereto to move on the outer surface of the round rod, thereby enhancing the stability of the scraper and the two moving blocks when moving.

[0022] Preferably, a motor is provided at one end of the fixed frame close to the reciprocating screw, and an output end of the motor is provided at one end of the reciprocating screw penetrating the fixed frame.

[0023] The technical effect of adopting the above further scheme is: when the staff controls the motor located outside the water to work, the reciprocating screw is driven to rotate, and when the reciprocating screw rotates, the moving block threadably mounted thereon is driven to reciprocate vertically on the fixed frame.

[0024] Compared with the prior art, the advantages and positive effects of the utility model are:

When the scraper 701 moves to the slide groove 201, it pushes the lifting block 202 to move. When the lifting block 202 moves, it drives the rotating axe 203 to rotate at one end of the connecting block 205, so that the rotating axe 203 is misaligned with the arc plate 902. After the arc plate 902 loses its restriction, the elastic member 901 contracts from the stretched state, driving the telescopic rod 9 and the push plate 10 to move toward the collection box 4 on the scraper 701, which is conducive to cleaning the debris on the scraper 701 to the collection box 4. Inside the collecting box 4, the scraper 701 is cleaned to prevent the debris on the surface of the scraper 701 from floating in the water when it enters the water and drifting to the trash rack body 3 with the water flow again, which is beneficial to improving the cleaning effect. The two ends of the counterweight rod 204 are respectively fixed to the opposite ends of the two rotating axes 203 to enhance the stability among the three. The counterweight rod 204 is convenient for adding weight to the rotating axe 203, so that when the rotating axe 203 rotates toward the base 1, the arc plate 902 is forced to drive the telescopic rod 9 and the push plate 10 away from the collecting box 4, and the elastic member 901 is stretched by the arc plate 902.

When the scraper 701 moves to the slide 201, it pushes the lifting block 202 to move, and the lifting block 202 is lifted. When the lowering block 202 moves, it drives the rotating axe 203 to rotate at one end of the connecting block 205, so that the rotating axe 203 is misaligned with the arc plate 902. After the arc plate 902 loses its restriction, the elastic member 901 contracts from the stretched state and drives the telescopic rod 9 and the push plate 10 to move toward the collection box 4 on the scraper 701, which is conducive to cleaning the debris on the scraper 701 into the collection box 4, cleaning the scraper 701, and preventing the debris on the surface of the scraper 701 from floating in the water when it enters the water and flowing again with the water flow The situation that it drifts onto the trash rack body 3 is conducive to improving the cleaning effect. The two ends of the counterweight rod 204 are respectively fixed to the opposite ends of the two rotating axes 203 to enhance the stability among the three. The counterweight rod 204 is convenient for adding weight to the rotating axe 203, so that when the rotating axe 203 rotates toward the base 1, the arc plate 902 is forced to drive the telescopic rod 9 and the push plate 10 away from the collection box 4, and the elastic member 901 is stretched by the arc plate 902.
