Description

Technical Field

[0001] The utility model specifically relates to the technical field of flood control and drainage, in particular to a pump for urban flood control and drainage. Background Art

[0002] Flood control and drainage pump stations are usually equipped with high-power water pumps and other equipment to ensure that they have strong pumping and drainage capabilities; these pump stations are generally reasonably laid out according to the characteristics of urban waterlogging to form an effective flood control and drainage system. For example, in some low-lying urban areas, flood control and drainage pumps can quickly discharge a large amount of accumulated water after a rainstorm to avoid problems such as traffic paralysis and house damage caused by urban waterlogging; in riverside areas, pump stations can play a key role during floods to reduce the threat of floods to coastal residents and infrastructure; in short, flood control and drainage pump stations play an indispensable role in protecting people’s lives and property and promoting sustainable economic and social development;

[0003] However, when the traditional urban flood control and drainage pump is in use, there will be a lot of garbage in the accumulated water due to urban waterlogging. In this way, when the pump is pumped through the pump body, the garbage will enter the pump body. If it cannot be cleaned in time, it will cause the water inlet pipe and the pump body to be blocked, and the working efficiency of the pump body cannot be effectively guaranteed. At present, when the traditional grid is connected to the pipeline, it is usually installed in a fixed manner. Although this can effectively fix the grid, it is not convenient to disassemble or replace the grid when the grid is blocked or damaged.

[0004] After searching, Chinese patent publication number CN202320820928.9 discloses a river flood control and drainage pump station structure; including: a main assembly; a cleaning assembly, including a first motor, a first rotating shaft connected to the first motor, a driving wheel connected to the front end of the first rotating shaft, a driven wheel rotatably connected to the driving wheel, a second rotating shaft transferred to the driven wheel, a fixing ring connected to the front end of the second rotating shaft, and a stirring rod connected to the front end of the fixing ring; a replacement assembly;

[0005] Although the structure in the above patent can achieve the effect of flood control and drainage when working, the structure in the above patent will also extract the silt or aquatic plants in the river when pumping, which will easily cause the water inlet pipe of the pump body to be blocked. In serious cases, the sand or aquatic plants will enter the pump body and cause damage to the pump body, which cannot effectively ensure the working efficiency of the pump body. Although a cleaning component is provided in the above patent, a large amount of silt or aquatic plants will gather in the water inlet pipe during cleaning, which will cause the pump body to run idle and fail to effectively extract the water from the waterlogging in time.

[0006] In view of the above situation, we provide a pump for urban flood control and drainage. In this device, the pump body is connected to the engine, so that the pump body is effectively driven to work by the engine, and the working efficiency of the pump body can also be effectively adjusted by the engine. When working, the water inlet on the pump body is connected to the water inlet pipe, and an isolation grid is installed at the other end of the water inlet pipe. In this way, when water is extracted, larger impurities can be effectively prevented from entering the pump body and causing damage to the pump body. Through the cooperation of the isolation grid and multiple splints, the isolation grid and the splints can be effectively installed quickly. When the isolation grid is blocked or damaged, the first semicircular plate and the connecting rod are driven by the slip ring to move to the end away from the isolation grid. At this time, the connecting rod drives the second semicircular plate to rotate upward along the rotating shaft between the third semicircular plate and the L-shaped connecting block, so that multiple splints are opened at the same time, and the isolation grid and the splint are separated, which is convenient for disassembly, cleaning or replacement, and improves the efficiency of replacement.
