Abstract
Description
Technical Field
[0001] This utility model relates to the field of water inlet and drainage equipment, and in particular to a drainage and water inlet slag barrier structure. Background Technology
[0002] Drainage grates are installed on drainage wells, usually at drainage outlets in areas such as roadsides, sidewalks, squares, and parking lots. Their main function is to filter, collect, and guide water flow, while ensuring the safe and efficient operation of the drainage system.
[0003] To prevent sewage pipes from easily getting clogged, drainage screens are designed to filter out larger debris, preventing it from entering the sewage pipes. However, during heavy rain, rainwater collects and brings a large amount of fallen leaves and other debris that clogs the drainage screens. This reduces the inflow rate of the sewage pipes, prevents the drainage screens from draining properly, and causes water accumulation in the area.
[0004] To ensure normal urban drainage and prevent water accumulation during heavy rains, a large number of people are often needed to inspect and clean the drainage grilles above the pipes. This process is extremely labor-intensive. Therefore, a drainage inlet and debris interception structure is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a drainage inlet debris interception structure that can automatically clean and collect debris clogging the drainage grille, thereby reducing the manpower required for drainage system maintenance during rainy seasons.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] This utility model discloses a drainage, water inlet, and slag-blocking structure, including a drainage well inner frame for being embedded in the drainage well. The inner wall of the drainage well inner frame is provided with a cover plate, and the top of the cover plate has a drainage hole extending through to the bottom of the cover plate. A collection box is provided on the left side of the drainage well inner frame, and the inner top wall of the collection box is detachably provided with an electric push rod. The output end of the electric push rod is detachably provided with a stacked plate, and the bottom of the stacked plate has a water outlet hole extending through to the top of the stacked plate. The stacked plate is attached to the bottom of the cover plate, and the water outlet hole and the drainage hole have the same specifications and are vertically aligned.
[0008] The inner wall of the drainage well inner frame has a slag inlet hole on the left side, which penetrates the drainage well inner frame and the collection box. A U-shaped seat is fixedly installed on the left side of the inner wall of the drainage well inner frame, located below the slag inlet hole. A movable plate is hinged inside the U-shaped seat. A counterweight is fixedly installed at the bottom of the movable plate. A locking block is fixedly installed on the right side of the inner wall of the drainage well inner frame. The counterweight and the locking block are in contact.
[0009] The collection box is equipped with a traction assembly, which has a traction cable at one end that is fixedly connected to the movable plate. The traction assembly is used to wind up the traction cable to make the movable plate rotate counterclockwise around the U-shaped seat.
[0010] As a preferred embodiment of this utility model, two U-shaped guide rails are fixedly installed on the left side of the inner frame of the drainage well, and U-shaped sliders extending into the U-shaped guide rails are fixedly installed on both the front and back of the collection box.
[0011] As a preferred embodiment of this utility model, a partition is fixedly installed inside the collection box, and the partition is located between the slag inlet and the traction assembly.
[0012] As a preferred embodiment of this utility model, the electric push rod is detachably connected to the collection box by screws, and the output end of the electric push rod is detachably connected to the stack plate by screws.
[0013] As a preferred technical solution of this utility model, the top of the collection box is provided with a handle and a movable door. The handle is used to lift the collection box and move it upwards, and the movable door is used to open and maintain the inside of the collection box.
[0014] As a preferred embodiment of this utility model, the traction assembly includes a traction motor fixedly mounted on the inner wall of the collection box, a take-up reel fixedly mounted on the output shaft of the traction motor, and one end of the traction cable wound around the outside of the take-up reel.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model, by setting an electric push rod, stacked plate, movable plate and traction component, sets the width of the water outlet and the drainage hole to be three times that of a normal drainage grid. When draining and blocking debris normally, the traction component drives the movable plate to rotate counterclockwise and lean against the left side of the inner wall of the drainage well frame. The electric push rod drives the stacked plate to move to the left, and the water outlet and the drainage hole partially overlap and correspond. The drainage channel is the size of the channel of a normal drainage grid.
[0017] During heavy rain or storms, a large amount of fallen leaves and debris are washed onto the cover plate, clogging the channels of the normal drainage grille. At this time, the traction component drives the movable plate to rotate clockwise, the counterweight and the locking block come into contact, and the electric push rod drives the stacked plate to the right, so that the water outlet and the drainage hole are completely aligned. The channel, which is three times the size of the normal drainage grille, allows fallen leaves and other debris to pass through. The debris is washed into the collection box by the water flow along the movable plate, thus completing the cleaning and collection of the blockage.
[0018] After the rain stops, staff open the access door, detach the traction cable from the reel, separate the output end of the electric push rod from the stack plate, pull up to remove the collection box, collect the debris inside the collection box, and then reset it. Attached Figure Description
