Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a municipal building drainage structure. Background Art

[0002] Municipal buildings refer to public buildings built with government funds, and refer to various administrative buildings and buildings serving the public within the planning area, including government buildings, public entertainment facilities, urban transportation facilities, educational, scientific research and cultural institutions, medical and health institutions, etc. During the construction of municipal buildings, drainage mechanisms must be set up to drain the top floors of buildings to prevent water accumulation on the top floors of buildings and erosion of buildings. The drainage structure of a building is a key structure of a building. A good drainage structure discharges rainwater from buildings on rainy days, which helps to keep the interior dry and reduce the corrosion of rainwater to buildings. When it rains, water will flow down along the roof. In order to prevent water from entering the room and causing damage to the walls near the lowest end of the roof, a drainage system is usually set up to divert and recycle the water flowing down from the roof. Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes", which are called municipal drainage pipes in engineering.

[0003] During rain, dust and impurities on the top floor of the building will be discharged along the drainage device, but in the prior art, most drainage devices are unable to dredge the interior of the drainage device. Dust and impurities washed away during the rainy season will accumulate on the surface of the filter, causing the drainage device to be blocked and unable to drain. Therefore, those skilled in the art provide a road drainage device to solve the problems raised in the above background technology. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a municipal building drainage structure, which aims to improve the problem that dust and impurities on the top floor of the building will be discharged along the drainage device during rain. However, in the prior art, most drainage devices are unable to dredge the interior of the drainage device. The dust and impurities washed away during the rainy season will accumulate on the surface of the filter screen, causing the drainage device to be blocked and unable to drain water.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a municipal building drainage structure, including a drainage pipe, the interior of the drainage pipe is fixedly connected with a fixed rod, the middle part of the fixed rod is rotatably connected with a rotating rod, a plurality of groups of spiral fan blades are installed on the outside of the rotating rod, one end of the rotating rod is fixedly connected with a mounting seat, the other end of the mounting seat is fixedly connected with a fixed block, a plurality of groups of springs a are arranged inside the fixed block, the interior of the fixed block is slidably connected with a limiting plate, one side of the limiting plate is fixedly connected with a connecting plate, and the other side of the connecting plate is fixedly connected with a brush.

[0006] Preferably, when draining the accumulated water on the top floor of the building, the water flows downward along the inside of the drainage pipe. At this time, the potential energy generated by the water flowing from high to low drives the spiral fan blades to rotate, and then drives the rotating rod to rotate, thereby driving the fixed block and its internal structure to rotate synchronously, thereby driving the top end of the brush to rotate close to the bottom surface of the filter, thereby cleaning the bottom surface of the filter during the drainage process, and preventing the garbage accumulated on the filter from causing internal blockage of the drainage pipe 1.

[0007] As a further description of the above technical solution:

[0008] One end of the drainage pipe is fixedly connected to a mounting ring, a filter is arranged inside the mounting ring, a clamping groove is opened inside one side of the filter, a mounting block is fixedly connected to the outside of the mounting ring, a limiting groove is opened inside the mounting block, a spring b is arranged inside the mounting block, the mounting block is slidably connected to the limiting block inside, a movable rod is fixedly connected to one side of the limiting block, a connecting rod is rotatably connected to one side of the limiting block, and the other end of the connecting rod is rotatably connected to the clamping block.

[0009] Preferably, when maintenance personnel need to disassemble the filter, they press the movable rod toward the inside of the mounting block, driving the movable rod to move toward the side of the mounting block close to the mounting ring and driving the limit block to slide, so as to compress the spring b. When the limit block moves, it drives the connecting rod to rotate, and when the connecting rod rotates, it pulls the card block to slide to the side away from the drainage pipe. When the outside of one end of the card block completely slides into the inside of the mounting block, the outside of the card block is separated from the inside of the card slot, so that maintenance personnel can disassemble the filter more quickly than traditional bolt and nut disassembly operations, which makes it convenient for maintenance personnel to inspect and repair damaged equipment.

[0010] As a further description of the above technical solution:

[0011] One end of the spring a is fixedly connected to one side of the interior of the fixed block, and the other end of the spring a is fixedly connected to one side of the limiting plate.

[0012] Preferably, spring a is used to provide elastic force.

[0013] As a further description of the above technical solution:

[0014] One end of the clamping block passes through the mounting block and the mounting ring in sequence, and the outer portion of one end of the clamping block is clamped with the inner portion of the clamping slot.

[0015] Preferably, the block fixes the position of the filter screen.

[0016] As a further description of the above technical solution:

[0017] One side of the spring b is fixedly connected to one side of the interior of the mounting block, and the other end of the spring b is fixedly connected to one side of the limiting block.

[0018] Preferably, the spring b provides elastic force.

[0019] As a further description of the above technical solution:

[0020] The connecting rod is arranged inside the limiting groove.

[0021] Preferably, the connecting rod transmits the movement of the limit block.

[0022] As a further description of the above technical solution:

[0023] The top end of the brush contacts the bottom end of the filter screen.

[0024] Preferably, a brush is used to clean debris on the filter screen.

[0025] As a further description of the above technical solution:

[0026] The outer sleeve of the movable rod is provided with a rubber sleeve.

[0027] Preferably, a rubber boot provides protection and sealing.

[0028] The utility model has the following beneficial effects:

[0029] 1. In the utility model, through the cooperation of the fixed rod, the rotating rod, the spiral fan blade, the mounting seat, the fixed block, the spring a, the limit plate, the connecting plate and the brush, the dust and impurities accumulated on the surface of the filter screen can be cleaned during the drainage process, thereby preventing the garbage accumulated on the filter screen from clogging the drainage pipe.

[0030] 2. In the utility model, through the cooperation of the card slot, the mounting block, the spring b, the limit block, the movable rod, the connecting rod and the card block, the maintenance personnel can disassemble the filter plate more quickly than the traditional disassembly operation of bolts and nuts, thereby facilitating the maintenance personnel to inspect and repair the damaged equipment.
