Abstract
Description
Technical Field
[0001] The present application relates to the technical field of drainage devices, and in particular to an asphalt pavement drainage device. Background Art
[0002] Asphalt pavement, in layman's terms, is a road paved with asphalt materials. Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is in liquid form, with a black surface and is soluble in carbon disulfide. It is a widely used waterproof, moisture-proof and anti-corrosion organic gelling material. Because of the above characteristics of asphalt materials, asphalt pavement also has high resistance to damage, smooth pavement, less dust, impermeable, durable and other high-quality characteristics. It is a typical flexible pavement. The maintenance and upkeep costs of asphalt pavement are high, but it can be repaired, while it is unlikely that cement concrete pavement can be completely repaired.
[0003] Most of the existing urban asphalt road pavement drainage is discharged into the urban drainage network through the water inlet holes of the rainwater manhole covers to ensure that rainwater does not accumulate on the road surface and to ensure traffic safety. This drainage method that relies on the gravity of the water flow limits the water flow velocity in the drainage pipe, resulting in limited unit drainage volume. When the rainfall is large, the rainwater will cover the road surface due to insufficient unit drainage volume, causing a full-filling phenomenon. At this time, it is difficult for the full-filled air to be discharged and exchanged from the inside of the drainage pipe, making it difficult for the rainwater to flow into the drainage pipe, resulting in a reduced efficiency of the rainwater flowing down into the drainage pipe. Therefore, an asphalt pavement drainage device is proposed to address the above problems. Utility Model Content
[0004] In view of the shortcomings of the prior art, the present application provides an asphalt pavement drainage device, which overcomes the shortcomings of the prior art and aims to solve the problem that the pavement drainage device cannot speed up the flow rate of discharged rainwater, resulting in insufficient drainage capacity during heavy rain days.
[0005] To achieve the above objectives, this application provides the following technical solutions:
[0006] A asphalt pavement drainage device comprises a rainwater well, a rainwater pressure cylinder is buried in the side of the rainwater well, the rainwater well and the rainwater pressure cylinder are connected by a first connecting channel, a pressure circuit studio is fixedly arranged on the top of the rainwater pressure cylinder, a driving motor is fixedly arranged in the pressure circuit studio, the bottom end of the driving motor output shaft is fixedly connected to a transmission shaft extending into the rainwater pressure cylinder, the transmission shaft is fixedly provided with spiral blades, a circuit controller is fixedly arranged in the pressure circuit studio, a water level sensor is fixedly arranged on the upper part of the side wall of the rainwater well, a water collection well is buried in the side of the rainwater pressure cylinder, the rainwater pressure cylinder and the water collection well are connected by a second connecting channel, and the bottom of the water collection well is connected to a rainwater and sewage main pipe.
[0007] By adopting the above technical solution, in heavy rain weather, too much rainwater accumulates in the rainwater well due to insufficient drainage capacity of the drainage device. This information can be monitored by the water level sensor. At this time, the drive motor drives the spiral blades to rotate, applying downward thrust to the rainwater in the rainwater pressure cylinder, increasing its flow rate, speeding up the drainage efficiency per unit time, and enabling the rainwater well to have an adsorption effect on the rainwater on the road surface, further improving the drainage efficiency and avoiding excessive rainwater accumulation on the road surface.
[0008] As a preferred technical solution of the present application, the end of the water level sensor is electrically connected to a signal transmission line, the end of the signal transmission line away from the water level sensor extends into the pressurized circuit working room and is electrically connected to the circuit controller, and the drive motor and the circuit controller are electrically connected through a control line.
[0009] By adopting the above technical solution, a complete working circuit can be constructed. When the water level sensor detects that there is too much water in the rainwater well, that is, the drainage load is large, the circuit controller will control the drive motor to work, pressurize the rainwater in the device to increase its flow rate, and improve the drainage efficiency.
[0010] As a preferred technical solution of the present application, the signal transmission line is wrapped with a waterproof casing and its two ends are respectively sealed and connected to the rainwater well and the side panels of the pressurized circuit studio.
[0011] By adopting the above technical solution, the signal transmission line can be protected and the overall waterproof performance of the device can be improved.
[0012] As a preferred technical solution of the present application, a waterproof bracket is fixedly arranged below the driving motor, and the driving motor is fixed to the upper end surface of the waterproof bracket by bolts. A waterproof bracket is fixedly arranged below the circuit controller, and the circuit controller is fixed to the upper end surface of the waterproof bracket by bolts.
[0013] By adopting the above technical solution, the drive motor and the circuit controller can be suspended to avoid water seepage into the bottom plate of the pressurized circuit studio, which may cause damage to the drive motor and the circuit controller circuit.
[0014] As a preferred technical solution of the present application, the top opening cover of the rainwater well is provided with a rainwater grate, and an anti-blocking filtering mechanism is provided in the rainwater well.
[0015] By adopting the above technical solution, a two-pass filtering structure can be formed to prevent foreign matter from entering the device and causing blockage in the drainage passage.
[0016] As a preferred technical solution of the present application, the anti-blocking filtering mechanism includes a fixing buckle fixedly arranged on the inner wall of the rainwater well, a filter frame is clamped on the fixing buckle, a lifting handle is fixedly arranged on the top of the filter frame, and a filter screen with a smooth surface is evenly laid on the filter frame.
[0017] By adopting the above technical solution, the rainwater that has been preliminarily filtered by the rain grate can be filtered more finely by the filter net. At the same time, since the fixing buckle and the filter net frame are detachably connected, the anti-blocking filter mechanism can be easily removed as a whole for cleaning.
[0018] As a preferred technical solution of the present application, the bottom of the upper opening of the first connecting channel is flush with the upper surface of the bottom plate of the rainwater well, and the bottom of the upper opening of the second connecting channel is flush with the upper surface of the bottom plate of the rainwater pressure cylinder.
[0019] By adopting the above technical solution, the flow path of rainwater can be made smoother.
[0020] The beneficial effects of the present application are as follows: when too much rainwater accumulates in the rainwater well, the water level sensor can monitor this information, and the circuit controller can control the drive motor to drive the spiral blades to rotate based on the information, thereby applying downward thrust to the rainwater in the rainwater pressure cylinder, increasing its flow rate, and speeding up the drainage efficiency per unit time. This situation can enable the rainwater well mouth to have an adsorption effect on the rainwater on the road surface, further improving the drainage efficiency and avoiding excessive rainwater accumulation on the road surface.
