Description

Technical Field

[0001] This invention belongs to the field of flood control and drainage technology, and specifically relates to a temporary drainage system for preventing urban flooding. Background Technology

[0002] In the process of urban construction and development, temporary drainage systems serve as crucial facilities for responding to emergencies such as rainstorms and flooding, playing a vital role in ensuring the normal operation of cities and the safety of people's lives and property. Currently, common temporary drainage systems mainly include emergency drainage facilities such as mobile water pumps and temporary pipeline laying, which have played a certain role in dealing with sudden waterlogging events.

[0003] However, existing temporary drainage systems have many shortcomings in practical applications. First, traditional temporary drainage equipment is bulky and complex in structure, making it difficult to deploy and move quickly, and unsuitable for drainage situations requiring emergency response. When sudden heavy rainfall in a city causes severe localized flooding, these devices often cannot function in a timely manner due to the excessive time required for transportation and installation.

[0004] Secondly, existing temporary drainage systems commonly suffer from debris blockage. Because urban floodwater often contains large amounts of debris such as leaves and plastic bags, traditional drainage systems lack effective filtration and debris separation mechanisms. This allows debris to easily enter drainage pipes and pumps, reducing drainage efficiency and potentially damaging equipment, severely impacting the system's continuous operation.

[0005] In summary, existing temporary drainage systems have significant shortcomings in terms of size, anti-clogging ability, and equipment protection, making it difficult to meet the modern city's demand for efficient, reliable, and convenient temporary drainage. Summary of the Invention

[0037] Reference Figures 1 to 7 A temporary drainage system for preventing waterlogging includes a base 100, a filter pipe 200, a drainage mechanism, and a sealing component 500.

[0038] A buoyancy module 110 is fitted to the outside of the base 100 to ensure that the base 100 floats on the water surface. A filter pipe 200 is fitted inside the base 100. One end of the filter pipe 200 is a water inlet 201, and the other end is a debris outlet 202. Both the water inlet 201 and the debris outlet 202 are located at the bottom of the base 100. When draining water, the water inlet 201 is below the water surface, and the debris outlet 202 is above the water surface. A side interface is provided on the filter pipe 200, and the drainage mechanism is connected to the filter pipe 200 through the side interface. A filter screen 320 is fitted at the side interface. A sealing component 500 is provided at the debris outlet 202 and includes a cover plate 510 and a rotary actuator 520. The rotary actuator 520 closes or opens the debris outlet 202 by rotating the cover plate 510.

[0039] In this application, the drainage mechanism includes a first pumping pipe 300, a second pumping pipe 310, a switching valve 350, a drainage pump 340, and a flow sensor 330. The bypass interface is divided into a first bypass interface 203 and a second bypass interface 204 arranged sequentially along the water flow direction. The first pumping pipe 300 is connected to the first bypass interface 203, and the second pumping pipe 310 is connected to the second bypass interface 204.

[0040] The switching valve 350 is a three-way valve structure with a first inlet 351, a second inlet 352, and an outlet valve 353, located between the filter pipe 200 and the drain pump 340. The first inlet 351 is connected to the first pumping pipe 300, and the second inlet 352 is connected to the second pumping pipe 310. The drain pump 340 has an inlet port 341 and an outlet port 342. The outlet valve 353 is connected to the inlet port 341 of the drain pump 340, and the outlet port 342 of the drain pump 340 is used to connect an external drain pipe. The switching valve 350 is used to selectively connect the first pumping pipe 300 or the second pumping pipe 310 to the drain pump 340. The flow sensor 330 is located between the switching valve 350 and the drain pump 340 and is used to detect the water flow rate pumped by the drain pump 340.

[0041] Specifically, the filter pipe 200 has an inverted U-shaped structure, including an ascending pipe section 205 and a descending pipe section 206. The inlet 201 is located at the bottom of the ascending pipe section 205, and the debris outlet 202 is located at the bottom of the descending pipe section 206. The first side interface 203 is located at the top of the descending pipe section 206, and the second side interface 204 is located in the middle of the descending pipe section 206. The inverted U-shaped filter pipe 200 structure can utilize gravity combined with water flow to flush out debris from the debris outlet 202. In addition, the U-shaped filter pipe 200 structure can prevent slender debris such as twigs from entering the descending pipe section 206 and affecting drainage.

[0042] Furthermore, the bottom of the riser section 205 is provided with a retractable connecting section 207, and a blocking component 400 is installed inside the connecting section 207. The blocking component 400 can block most debris from entering the filter pipe. The blocking component 400 includes a fixing frame 410, on which a water wheel 430 is mounted via a connecting shaft 420. The top of the connecting shaft 420 is provided with a stop 421, the top of which is higher than the end face of the connecting section 207. When the drainage is close to being completely drained, the stop 421 can prevent the retractable pipe from directly hitting the ground, thus affecting the pumping.

[0043] Furthermore, to reduce the risk of debris completely covering the filter screen 320, the filter screen 320 is a hemispherical structure that protrudes towards the center of the filter tube 200, which can significantly reduce the probability of mesh clogging. At the same time, the hemispherical structure has higher strength and improved impact resistance.

[0044] Furthermore, the base 100 is equipped with casters 120 and drive paddles 130 for moving the base 100. The drive paddles 130 provide autonomous movement, while the casters 120 assist in steering, allowing the equipment to be flexibly deployed to flooded areas, reducing the need for manual handling. This is particularly suitable for emergency rescue scenarios where frequent repositioning is required. The base 100 is equipped with a control module 140 and a camera module 150. The control module 140 is electrically connected to the flow sensor 330 and the switching valve 350, forming an automatic closed-loop control: when the flow rate is below a threshold, the pumping pipeline is automatically switched and an alarm is triggered. The camera module 150 provides real-time video of the scene, assisting in remote control or AI-based obstacle recognition, improving the system's intelligence and operational safety. A waterproof camera 160 is located at the bottom of the base 100. The waterproof camera 160 can directly observe the underwater environment near the inlet 201, monitoring debris accumulation or drainage, providing decision-making support for the control module 140 (such as moving to a location with less debris).

[0045] The working principle of this technical solution is as follows: the switching valve 350 selects any water pumping pipe (such as the first water pumping pipe 300) to connect with the drainage pump 340, and the drainage pump 340 starts to perform drainage work. At this time, the sealing component 500 seals the debris outlet 202. The accumulated water enters from the inlet 201 of the filter pipe 200, is pumped by the drainage pump 340, enters the water pumping pipe, and is discharged from the outlet 342 of the drainage pump 340 through the switching valve 350 and the drainage pump 340.

[0046] After prolonged operation, debris will clog the filter screen 320. For example, after draining water through the first water pipe 300 for an extended period, debris such as leaves in the accumulated water will cover the filter screen 320 at the first side interface 203. After the flow sensor 330 detects a decrease in the water flow pumped by the drain pump 340, the control module 140 controls the switching valve 350 to switch, connecting the drain pipe and the second water pipe 310. The accumulated water is pumped from the first water pipe 300 to the second water pipe 310. During this period, the accumulated water in the filter pipe 200 will wash away the debris attached to the filter screen 320 at the first side interface 203 and flush it to the debris outlet 202 when it flows through the first side interface 203. Similarly, after draining water through the second water pipe 310 for a long time, debris will cover the filter screen 320 of the second side interface 204. The control module 140 controls the switching valve 350 to switch the connection between the drain pipe and the first water pipe 300. The water pumped from the second water pipe 310 is changed to be pumped from the first water pipe 300. The debris attached to the filter screen 320 of the side interface falls off to the debris outlet 202 after being flushed.

[0047] When there is too much debris in the filter tube 200, switching the water pump cannot increase the flow rate. The control module 140 controls the sealing component 500 to open the debris outlet 202. The debris falls off under the combined action of gravity and water flow, the filter tube 200 is emptied, and the system resumes operation.

[0048] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
