Description

Technical Field

[0001] The present invention relates to the technical field of drainage equipment, and more specifically, to a drainage structure for a municipal engineering project. Background Art

[0002] In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages), and provide paid or free public products and services to residents based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life falls into the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects, and various pipelines closely related to life: rainwater, sewage, water supply, recycled water, electricity (part outside the red line), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all fall into the category of municipal engineering.

[0003] The actual water inlet structure of the drainage structure for municipal engineering is fixed, which leads to slow discharge of water when the water flow is turbulent, and then causes waste to block the water inlet, resulting in a reduction in the actual water intake, affecting the actual drainage effect of the equipment. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a municipal engineering drainage structure, which continuously presses the second water flow leakage plate as a whole, and the second water flow leakage plate as a whole is in an up and down movement state. The water source blocked by the top of the first water flow leakage plate impacts the second water flow leakage plate as a whole, so that the silt and debris are diluted, and the silt and debris flow into the interior of the drainage pipe seat, preventing the silt and debris from clogging the entire equipment, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a municipal engineering drainage structure, comprising a base, a drainage pipe seat is clamped inside the base, a limiting plug strip is fixedly connected to the inner wall of the base, and one end of the limiting plug strip is clamped on the top of the drainage pipe seat, a first water flow leakage plate is provided inside the drainage pipe seat, a clamping strip is fixedly connected to the bottom of the first water flow leakage plate, and the bottom of the clamping strip is clamped inside the drainage pipe seat, a first diverter ring is fixedly connected to the top of the first water flow leakage plate, a second water flow leakage plate is fixedly connected to the top of the first diverter ring, a first extrusion buffer ring is fixedly connected between the second water flow leakage plate and the first water flow leakage plate, a second diverter ring is fixedly connected to the bottom of the second water flow leakage plate, multiple groups of through grooves are provided inside the second water flow leakage plate and the first water flow leakage plate, and a water flow guide sheet is fixedly connected to the bottom of the second water flow leakage plate.

[0006] By adopting the above technical solution, the base is pre-buried in the road drainage, the drainage pipe seat is clamped in the inside of the base, water flows through the surface of the drainage pipe seat for drainage, and a first water flow leakage plate is arranged on the top of the drainage pipe seat. The first water flow leakage plate is clamped in the inside of the drainage pipe seat through the clamping strip at the bottom of the first water flow leakage plate, so as to prevent the first water flow leakage plate from being displaced due to the impact of water flow during use, thereby affecting the use effect.

[0007] In a preferred embodiment, the number of the clamping strips is two groups, and the two groups of clamping strips are axially symmetrically arranged with respect to the vertical center axis of the first water flow drain plate.

[0008] By adopting the above technical solution, the first water flow leakage plate is clamped to the top of the drain pipe seat through two sets of symmetrical clamping strips, so that the external water flow can flow into the drain pipe seat. The water flows through the first water flow leakage plate as a whole, and the impurities in the water flow are screened out to prevent the impurities from flowing into the drain pipe seat. The equipment as a whole drains water for a long time, and the impurities increase from a small amount to a large amount, which can easily cause blockage inside the drain pipe seat and increase the time for manual dredging.

[0009] In a preferred embodiment, a pressure rebound cover is fixedly connected between the first water flow leakage plate and the second water flow leakage plate, the interior of the pressure rebound cover is fixedly connected to a limiting seat, the interior of the pressure rebound cover is fixedly connected to a limiting column, and one end of the limiting column extends to the interior of the limiting seat, the outer wall of the limiting column is fixedly connected to a second extrusion buffer ring, and the second extrusion buffer ring is arranged at the bottom of the limiting seat in a wrapped state.

[0010] By adopting the above technical scheme, the second water flow leakage plate is pressed as a whole, so that the second water flow leakage plate as a whole moves up and down on the top of the first water flow leakage plate, and the torsion spring inside the pressure contact ring presses the support seat as a whole, so that the falling second water flow leakage plate squeezes the first extrusion buffer ring and the pressure rebound cover to release the pressure, and the elasticity of the pressure rebound cover and the torsion spring makes the second water flow leakage plate rebound, and the second water flow leakage plate as a whole is continuously pressed, and the second water flow leakage plate as a whole moves up and down, and the water source blocked at the top of the first water flow leakage plate impacts the second water flow leakage plate as a whole, so that the sludge and debris are diluted, and the diluted sludge is discharged by the impact of the external water flow, so as to prevent the accumulated sludge and debris from affecting the normal use of the drainage pipe seat.

[0011] In a preferred embodiment, the number of the pressure resilience shields is multiple, and the multiple groups of pressure resilience shields are arranged in a path array between the first water flow leakage plate and the second water flow leakage plate.

[0012] By adopting the above technical solution, multiple groups of pressure rebound covers are vertically arranged between the first water flow leakage plate and the second water flow leakage plate, and the first water flow leakage plate and the second water flow leakage plate are supported as a whole by the multiple groups of pressure rebound covers to prevent the second water flow leakage plate from being unable to achieve the expected up and down movement trajectory due to uneven force supported by the pressure rebound covers on the bottom of the second water flow leakage plate when the second water flow leakage plate is pressed as a whole.

[0013] In a preferred embodiment, a pressure dividing ring is fixedly connected to the top of the first water flow leakage plate, a support seat is provided on the top of the pressure dividing ring, a pressure contact ring is provided on the top of the support seat, a torsion spring is provided inside the pressure dividing ring and the pressure contact ring, and the torsion spring is fixedly connected inside the support seat.

[0014] By adopting the above technical solution, torsion springs are provided inside the pressure dividing ring and the pressure contact ring. When the pressure rebound cover falls and is deformed, the torsion spring presses the pressure dividing ring and the pressure contact ring to support the falling force of the pressure rebound cover. When the pressure rebound cover rebounds, the elasticity of the torsion spring is used to lift up the pressure rebound cover, so that the pressure rebound cover as a whole quickly returns to its original shape.

[0015] In a preferred embodiment, the pressure dividing rings are provided in multiple groups, and the multiple groups of pressure dividing rings are arranged in a path array with respect to the top of the first water flow leakage plate.

[0016] By adopting the above technical solution, the falling force of the pressure rebound cover is supported by multiple groups of pressure distribution rings, thereby preventing the pressure rebound cover from falling excessively and being unable to restore its original shape.

[0017] In a preferred embodiment, a gravity bar is provided inside the water flow guide plate, a cavity is opened inside the water flow guide plate, a swing arm is hinged on the inner wall of the cavity, a collision spring is sleeved on the outer wall of the swing arm, and the collision spring is arranged inside the cavity, an elastic sheet is fixedly connected to the inner wall of the cavity, and one end of the elastic sheet is fixedly connected to the outer wall of the swing arm.

[0018] By adopting the above technical scheme, the water flow guide plate is arranged in an L-shape as a whole, so as to increase the contact area between the water flow and one end of the water flow guide plate. A collision spring and an elastic plate are arranged on the outer wall of the swing arm. The swing arm as a whole is pulled by the collision spring and the elastic plate, so that the swing arm as a whole accelerates the swinging speed to hit the inner wall of the cavity. When one end of the water flow guide plate is hit by the water flow, the water flow guide plate as a whole is in a shaking and swinging state for a long time, thereby diverting the turbulent water flow and avoiding excessive water flow velocity, which causes slow inflow.

[0019] Technical effects and advantages of the present invention:

[0020] The second water flow leakage plate rebounds through the elasticity of the pressure rebound cover and the torsion spring, and the second water flow leakage plate is continuously pressed as a whole, so that the second water flow leakage plate as a whole moves up and down, and the water source blocked at the top of the first water flow leakage plate impacts the second water flow leakage plate as a whole, so that the sludge and debris are diluted, and the sludge and debris flow into the inside of the drainage pipe seat, and flow into the drainage pipe seat through the external water source, so as to flush the second water flow leakage plate and the first water flow leakage plate, thereby preventing the sludge and debris from clogging the entire equipment;

[0021] When the water flow guide plate is hit and swings, the swing arm inside the cavity is in a swinging state, hitting the inner wall of the cavity, generating vibration, and accelerating the water flow guidance. A collision spring and an elastic sheet are arranged on the outer wall of the swing arm. The collision spring and the elastic sheet pull the swing arm as a whole, so that the swing arm as a whole accelerates the swinging speed to hit the inner wall of the cavity. When one end of the water flow guide plate is hit by the water flow, the water flow guide plate as a whole is in a shaking and swinging state for a long time, thereby diverting the turbulent water flow.
