Description

Technical Field

[0001] This utility model relates to the technical field of pollution interception equipment, specifically to a pollution interception device for water conservancy projects. Background Technology

[0002] A trash rack in water conservancy engineering is a facility installed in the water passage of a water conservancy structure to intercept floating objects such as branches and garbage in the water flow, so as to protect the hydraulic structure and canal system from blockage and damage.

[0003] Chinese patent with publication number CN206941544U discloses a trash rack, which includes side beams supported on two side piers, a top beam fixed to the top of the two side beams, a bottom beam fixed to the bottom of the two side beams, and rack plates arranged at intervals between the two side beams.

[0004] Regarding the aforementioned disclosed technologies, in the prior art, trash racks are often used in conjunction with lifting and cleaning equipment to remove floating debris from their surface by lifting or moving the trash rack. After the trash rack surface is covered with dirt, impurities can easily enter the gaps between the rack plates, resulting in a decrease in the surface cleanliness and efficiency of the rack plates. During cleaning and maintenance, since the trash rack is usually located underwater, it is inconvenient to carry out effective cleaning work, which not only increases the labor intensity of manual cleaning.

[0005] Therefore, a pollution interception device for water conservancy projects is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a water conservancy project pollution interception device in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

The output end of the servo motor is fixedly connected to a reel, and a steel cable is wound around the surface of the reel.

[0011] Furthermore, the cleaning assembly includes a cleaning box fixedly installed at the end of the steel cable, and drain doors are hinged to the two side walls of the cleaning box. The surface of the cleaning box is provided with water filter holes, and the movable plate is fixedly installed on the bottom surface of the cleaning box.

[0012] Furthermore, the synchronous cleaning assembly includes racks fixedly installed in the grooves on both sides of the U-shaped frame, two sets of side frames fixedly installed on the bottom surface of the movable plate, a rotating shaft rotatably inserted into the side frame, a cleaning brush fixedly sleeved on the surface of the rotating shaft, and cleaning brushes fixedly sleeved at both ends of the rotating shaft, with the cleaning brushes meshing with the racks.

[0013] Furthermore, the inner walls on both sides of the U-shaped frame are provided with guide grooves, and the two end faces of the movable plate are provided with limit wheels, which are located in the guide grooves inside the U-shaped frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] Installed inside the water channel via a U-shaped frame, the debris-blocking grid inside the U-shaped frame intercepts floating debris in the water. A lifting winch mechanism drives the cleaning component to move vertically upward along the surface of the debris-blocking grid. As the cleaning component moves vertically upward, the intercepted floating debris is collected inside the cleaning component.

[0027] like Figures 1 to 6As shown, a water conservancy project debris interception device includes a U-shaped frame 1 and a debris barrier 2 fixedly installed inside the U-shaped frame 1. A lifting winch mechanism 3 is fixedly installed on the U-shaped frame 1, and a debris cleaning component 4 is fixedly installed at the end of the lifting winch mechanism 3. A movable plate 5 is fixedly installed on the bottom surface of the debris cleaning component 4, and the movable plate 5 slides in close contact with the inside of the U-shaped frame 1. A synchronous cleaning component 6 is provided on the movable plate 5 and the U-shaped frame 1. More specifically, the U-shaped frame 1 is installed in a water channel, and the debris barrier 2 inside the U-shaped frame 1 intercepts floating objects in the water. The lifting winch mechanism 3 drives the debris cleaning component 4 to move vertically upward along the surface of the debris barrier 2. When the debris cleaning component 4 moves vertically upward, the intercepted floating objects are collected inside the debris cleaning component 4. At the same time, the synchronous cleaning component 6 cleans the surface and gaps of the debris barrier 2 during the vertical upward movement of the debris cleaning component 4, maintaining the cleanliness and efficiency of the debris barrier 2.

[0028] The trash rack 2 includes a steel frame 201 fixedly installed on the inner wall of the U-shaped frame 1, and reinforcing ribs 202 fixedly installed on the inner walls of both sides of the steel frame 201. Several sets of grid bars 203 are fixedly installed on the surface of the steel frame 201 and the reinforcing ribs 202. More specifically, the multiple sets of equidistantly arrayed grid bars 203 on the surface of the steel frame 201 and the reinforcing ribs 202 are used to intercept and filter impurities in the river water.

[0029] The lifting hoisting mechanism 3 includes a mounting frame 301 fixedly installed on the U-shaped frame 1. Servo motors 302 are fixedly installed on both side walls of the mounting frame 301. A reel 303 is fixedly connected to the output end of the servo motor 302, and a steel cable 304 is wound around the surface of the reel 303. More specifically, the servo motor 302 drives the reel 303 to rotate, thereby winding the steel cable 304 and causing the cleaning component 4 and the movable plate 5 to move vertically along the interior of the U-shaped frame 1. This allows the cleaning component 4 to clean and collect the impurities intercepted on the surface of the trash rack 2.

[0030] The cleaning assembly 4 includes a cleaning box 401 fixedly installed at the end of the steel cable 304, and drain doors 402 are hinged to both side walls of the cleaning box 401. Filter holes 403 are provided on the surface of the cleaning box 401, and a movable plate 5 is fixedly installed on the bottom surface of the cleaning box 401. More specifically, by moving the cleaning box 401 along the surface of the trash rack 2, impurities enter the interior of the cleaning box 401, and the drain doors 402 on both side walls of the cleaning box 401 allow for the cleaning of the collected impurities.

[0031] The synchronous cleaning assembly 6 includes racks 601 fixedly installed in the grooves on both sides of the inner wall of the U-shaped frame 1.

A cleaning brush 604 is fixedly sleeved on the surface of the rotating shaft 603. The cleaning brush 604 is fixedly sleeved at both ends of the rotating shaft 603, and the cleaning brush 604 is meshed with the rack 601. More specifically, when the cleaning assembly 4 and the movable plate 5 are moved vertically by the lifting winch mechanism 3, the gear 605 meshes with the rack 601, causing the gear 605 to roll along the surface of the rack 601. The gear 605 drives the rotating shaft 603 and the cleaning brush 604 to rotate, and the cleaning brush 604 cleans the surface of the trash rack 2 through the brush bristles.

[0032] The inner walls on both sides of the U-shaped frame 1 are provided with guide grooves, and the two ends of the movable plate 5 are provided with limit wheels, which are located in the guide grooves inside the U-shaped frame 1. More specifically, the limit wheels at both ends of the movable plate 5 are located in the guide grooves on both sides of the inner walls of the U-shaped frame 1, thereby limiting the vertical movement of the movable plate 5.

[0033] In summary: The U-shaped frame 1 is installed inside the water channel, and the debris barrier 2 inside the U-shaped frame 1 intercepts floating objects in the water. The lifting hoisting mechanism 3 drives the cleaning component 4 to move vertically upward along the surface of the debris barrier 2. When the cleaning component 4 moves vertically upward, the intercepted floating objects are collected inside the cleaning component 4. At the same time, the synchronous cleaning component 6 cleans the surface and gaps of the debris barrier 2 during the vertical upward movement of the cleaning component 4, maintaining the cleanliness and efficiency of the debris barrier 2.
