Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and pollution cleaning, and particularly relates to a water conservancy pollution cleaning device. Background Art

[0002] Trash racks for intercepting dirt in water are provided at the water turbine of a power station or the water intake of a pumping station to prevent this dirt from endangering the safe operation of the water turbine or the pumping station. For the dirt attached to the front side of the trash rack, i.e., the side facing the water flow, and the dirt accumulated in front of the trash rack, a rake bucket is generally used for cleaning to avoid the head loss caused by this dirt and endanger the safety of the trash rack. To facilitate the lifting of the rake bucket along the trash rack, the trash rack generally includes a bracket and vertically and uniformly arranged bars on the front side of the bracket; such as the trash rack in the hydraulic pollution cleaning rake bucket of the submersible trash rack of the utility model patent with the publication number CN205012303U.

[0003] In the prior art, such as the invention patent of the mechanically pressurized pollution cleaning rake bucket capable of connecting a multi-magnification lifting device with the publication number CN105350507B; the utility model patent of an enhanced force type mechanical pollution cleaning rake bucket with the publication number CN205604202U; both realize the lifting in front of the trash rack by connecting a hoisting device through a pulley, and grab the dirt in front of the trash rack through fixed rake teeth and rotatable rake teeth. During operation, the fixed rake teeth move downward from top to bottom between the bars to the lower end of the trash rack to separate the dirt from the trash rack, and then the rotatable rake teeth rotate to cooperate with the fixed rake teeth to grab the dirt. The rotatable rake teeth and the fixed rake teeth bite end to end and move upward between the bars from bottom to top to lift the dirt to the water surface at the lifting place, realizing the cleaning of the grille.

[0004] Due to the need to cooperate with the above-mentioned rake bucket, the trash racks of the prior art rake bucket cleaners are all provided with vertical bars, and there is no structure for lateral dirt interception, which makes it easy for some thin strip-shaped sundries to pass through between the bars, restricting the improvement of the dirt interception ability. The utility model patent of a trash rack for reservoir projects with the publication number CN214695478U has a lateral dirt interception plate, but it is not convenient to cooperate with the rake bucket to clean the dirt intercepted by the trash rack. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the water conservancy rake bucket trash rack lacks an effective lateral dirt interception structure that does not affect the operation of the rake bucket, and to provide a water conservancy pollution cleaning device.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A water conservancy pollution cleaning device includes a bracket, and a number of mutually parallel and vertical bars are provided on the front side of the bracket; the water conservancy pollution cleaning device further includes:

[0008] A number of baffles are arranged horizontally and parallel to each other. Grooves corresponding to the grid bars one by one are provided at the front of each baffle, and the grid bars pass through the inner sides of the grooves.

[0009] A bi-directional rebound assembly, the rear end of the baffle is rotatably connected to the bi-directional rebound assembly, so that the front part of the baffle can be turned up and down respectively under the drive of an external force. When the external force is eliminated, the bi-directional rebound assembly resets the baffle.

[0010] The beneficial effects are as follows: The horizontal baffle can be turned up and down, improving the sewage interception ability and not affecting the up and down movement of the rake teeth of the grab bucket; the baffle is supported by the bi-directional rebound assembly, which can not only support the turning of the baffle when driven by the rake teeth, but also automatically reset the baffle after the rake teeth leave, thus not affecting the cleaning of the sundries in front of the grille by the grab bucket, ensuring the sewage interception ability and taking into account the water flow passability.

[0011] Furthermore, the front end face of the baffle is flush with the front side face of the grid bar.

[0012] The beneficial effects are as follows: It reduces the unevenness of the interception cross-section, improves the flatness of the interception cross-section, concentrates the dirt, and facilitates the grab bucket to comprehensively grab the dirt in front of the grille.

[0013] Furthermore, it includes a grab bucket that can be lifted and lowered along the front side of the bracket, and guide rails for guiding the grab bucket are connected to the left and right sides of the bracket.

[0014] The beneficial effects are as follows: The guide rails ensure that the grab bucket stably lifts and lowers along the front of the grille, thereby realizing the collection of dirt.

[0015] Furthermore, the bi-directional rebound assembly includes a U-shaped plate. The opening of the U-shaped plate faces forward and is fixedly connected to the rear side of the edge of the bracket. Rotating shafts are provided at the left and right sides of the rear end of the baffle and are rotatably connected to the middle part of the rear end of the U-shaped plate.

[0016] The beneficial effects are as follows: The baffle is rotatably connected to the U-shaped plate, enabling the baffle to turn downwards or upwards when driven by an external force.

[0017] Furthermore, a movable part is provided inside the U-shaped plate. The movable part is in a rectangular frame structure. Limit columns are provided on the left and right sides of the middle part of the baffle. The limit columns pass through the middle part of the movable part, and a number of elastic supports are connected between the rear side of the movable part and the rear wall of the U-shaped plate.

[0018] The beneficial effects are as follows: When the baffle turns up or down, the movable part can be driven to move backward through the limit columns, compressing the elastic supports. When the external force is eliminated, the elastic supports rebound to reset the baffle.

[0019] Furthermore, the elastic support includes a telescopic rod, and a spring is sleeved outside the telescopic rod; both the telescopic rod and the spring are connected between the movable part and the U-shaped plate.

[0020] The beneficial effects are as follows: As an energy storage component, the spring deforms and stores energy when subjected to an external force, and releases the stored elastic potential energy when the external force is removed; the telescopic rod provides guidance for the movement of the movable part, enables the movable part to move linearly, and ensures the consistency of the two-side flipping.

[0021] Furthermore, the telescopic rod is a damping telescopic rod.

[0022] The beneficial effects are as follows: It improves the stability during reset and reduces the shaking of the baffle. Description of the Drawings

[0037] Specific embodiments of the water conservancy sewage cleaning device provided by the present invention:

[0038] Please refer to Figure 1-8 , a water conservancy sewage cleaning device, comprising a bracket 1, a grid bar 2, a baffle 3, a bi-directional resilient component 4, a rake bucket 5 and a track 6.

[0039] A plurality of mutually parallel and vertical grid bars 2 are provided on the front side of the bracket 1; the grid bars 2 divide the water passing surface into a plurality of vertical units, making it difficult for dirt to pass through and realizing sewage interception.

[0040] A number of baffles 3 are arranged horizontally and are parallel to each other, further reducing the area of the trash interception unit and improving the trash interception capacity. When installed, the baffles 3 are made to be as parallel as possible to the direction of the water flow. While improving the trash interception capacity, the obstruction to the water flow is reduced to ensure the water flow passability.

[0041] A number of grooves 31 corresponding one-to-one with the grid bars 2 are provided at the front of each baffle 3, and the grid bars 2 pass through the inner sides of the grooves 31; the front end face of the baffle 3 is flush with the front side face of the grid bars 2. The unevenness of the intercepted surface is reduced, the flatness of the intercepted surface is improved, the dirt is concentrated, and it is convenient for the rake bucket 5 to comprehensively grab the dirt in front of the grid.

[0042] The rake bucket 5 moves up and down along the front side of the support 1, and guide rails 6 for guiding the rake bucket 5 are connected to the left and right sides of the support 1. The guide rails 6 ensure that the rake bucket 5 stably moves up and down in front of the grid, thereby realizing the collection of dirt.

[0043] As Figure 4 shown, the rake bucket 5 includes a main body which is of a steel structure. A pulley block is provided on the upper side of the main body for facilitating connection with a hoisting device. Guide wheels for cooperating with the guide rails 6 are provided on both sides of the main body. The cross-section of the guide rails 6 is U-shaped, and the guide wheels roll along the inner side of the guide rails 6. Fixed rake teeth are provided on the lower side of the main body and can move up and down between the grid bars 2. A rotatable rake tooth is rotatably connected to the lower part of the main body and cooperates with the fixed rake teeth to grab dirt. A hydraulic cylinder is hinged between the main body and the middle part of the rotatable rake tooth, and the hydraulic cylinder drives the rotatable rake tooth to flip.

[0044] Both the left and right sides of the rear end of the baffle 3 are rotatably connected to the bi-directional resilient component 4. The bi-directional resilient component 4 enables the front part of the baffle 3 to flip up and down respectively under the drive of an external force. When the external force is eliminated, the bi-directional resilient component 4 resets the baffle 3.

[0045] The bi-directional resilient component 4 includes a U-shaped plate 41. The opening of the U-shaped plate 41 faces forward and is fixedly connected to the rear side of the left or right edge of the support 1. Rotating shafts 32 are provided at both the left and right sides of the rear end of the baffle 3 and are rotatably connected to the middle part of the rear end of the U-shaped plate 41. Two bi-directional resilient components 4 correspond to each baffle 3. The baffle 3 is rotatably connected to the U-shaped plate 41, enabling the baffle 3 to flip downwards or upwards when driven by an external force.

[0046] An active part 42 is arranged inside the U-shaped plate 41. The active part 42 is of a rectangular frame structure. Limit columns 33 are provided on both the left and right sides of the middle part of the baffle 3. The limit columns 33 pass through the middle part of the active part 42. A number of elastic supports are connected between the rear side of the active part 42 and the rear wall of the U-shaped plate 41. When the baffle 3 flips up or down, the active part 42 can be driven to move rearward through the limit columns 33, compressing the elastic supports. When the external force is eliminated, the elastic supports rebound to reset the baffle 3.

[0047] The elastic support includes a telescopic rod 44, and a spring 43 is sleeved outside the telescopic rod 44; both the telescopic rod 44 and the spring 43 are connected between the movable member 42 and the U-shaped plate 41. Two elastic supports are connected between the movable member 42 and the U-shaped plate 41, and the two elastic supports are respectively connected to the upper and lower parts of the movable member 42. The spring 43 serves as an energy storage element, deforming and storing energy when subjected to an external force, and releasing the stored elastic potential energy when the external force is eliminated; the telescopic rod 44 provides guidance for the movement of the movable member 42, enables the movable member 42 to move linearly, and ensures the consistency of the flipping on both sides.

[0048] In this embodiment, the telescopic rod 44 is a damping telescopic rod, and the damping effect improves the stability when the baffle 3 resets and reduces the shaking of the baffle 3.

[0049] In some other embodiments, the elastic support can be replaced by a rod body that simultaneously has elastic, damping, and telescopic functions.

[0050] Dirt cleaning process: Water flows through the vertical grid bars 2 and the horizontal baffles 3, and the dirt in the water is blocked; compared with the prior art where there is only a vertical strip structure, the anti-fouling ability of this device is significantly improved, reducing the failure rate of equipment such as downstream pumping stations and power stations;

[0051] When a large amount of dirt accumulates in front of the grid and affects the water flow throughability, the dirt in front of the grid is grabbed by the rake bucket 5;

[0052] Lower the rake bucket 5. When the rake bucket 5 descends, the rotatable rake teeth are in an open state, as shown in Figure 5 ; the fixed rake teeth descend through between the grid bars 2, causing the dirt to break away from in front of the grid, causing the front ends of the baffles 3 to flip downward from top to bottom, the limit posts 33 to move downward, and the movable member 42 to move backward to compress the elastic support. After the fixed rake teeth pass through the baffle 3, the elastic support makes the movable member 42 move forward to reset and the limit posts 33 to reset, thereby making the baffle 3 reset;

[0053] The rake bucket 5 moves to the lower end in front of the grid, and the dirt is concentrated at the front side of the bottom in front of the grid. Actuate the hydraulic cylinder to drive the rotatable rake teeth to close, cooperate with the fixed rake teeth to grab the dirt, and then move upward;

[0054] When the ends of the rotatable rake teeth and the fixed rake teeth move upward, they pass through between the grid bars 2, causing the front ends of the baffles 3 to flip upward from bottom to top. When the baffle 3 flips upward, the limit posts 33 move upward, and similarly, the movable member 42 can be moved backward to compress the elastic support. After the rake teeth leave the baffle 3, the elastic support makes the baffle 3 reset.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
