Description

Technical Field

[0001] This utility model relates to the field of drainage technology in water conservancy projects, and in particular to drainage devices for water conservancy projects. Background Technology

[0002] Drainage in water conservancy projects refers to the removal of excess water from water bodies through various facilities and equipment to prevent floods, waterlogging, and other water-related damage to the environment and infrastructure. Common drainage facilities include drainage ditches, drainage pipes, pumping stations, and spillways. An effective drainage system can control water flow, regulate water levels, ensure the normal operation of agricultural, urban, and industrial areas, and promote the rational use of water resources. Drainage projects play a vital role in flood control, disaster prevention, and irrigation. When using drainage pipes, it is necessary to prevent the pipes from being blocked by debris during drainage; therefore, water conservancy drainage devices are required.

[0003] According to the Chinese patent "A Drainage Machine for Water Conservancy Projects" authorized announcement number "CN220802284U", by setting up elastic components and drive components, the filter screen can be continuously vibrated during the drainage process, thereby preventing the filter screen mesh from being blocked by impurities, improving the water flow efficiency, and the drive component is powered by the water flow impact, which does not require electricity and is more low-carbon and environmentally friendly.

[0004] Although the above application can prevent the filter screen from becoming clogged by using the elastic component and the drive component to make the propeller blade drive the pressure plate to squeeze the filter screen and the spring to make the filter screen vibrate during the drainage process, the water flow will impact the impurities on the surface of the filter screen during the drainage process. Larger debris such as seaweed may adhere to the surface of the filter screen under the force of the water, and the filter screen cannot be cleaned by vibration alone.

[0005] Therefore, a drainage device for water conservancy projects is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a drainage device for water conservancy projects to solve the above-mentioned problems and improve the problem of easy clogging of filter screens.

[0007] This utility model achieves the above objectives through the following technical solution: a drainage device for water conservancy projects, comprising: a box body, wherein an inlet pipe and an outlet pipe are respectively provided at both ends of the box body, and a filter pipe is provided between the inlet pipe and the outlet pipe;

[0008] The filtration mechanism includes a filter box fixedly connected between the water inlet pipe and the filter pipe. A filter screen is fixedly connected to the inner wall of the filter box. A spiral blade is provided inside the filter pipe. One end of the spiral blade passes through the filter screen and is fixedly connected to a first scraper. A collection box is provided below the filter box, and a second scraper is fixedly connected inside the collection box.

[0009] Preferably, the filter box is circular with its two sides connected to the water inlet pipe and the filter pipe, respectively, and its lower part is connected to the collection box. This facilitates the collection of debris.

[0010] Preferably, the second scraper is inclinedly disposed inside the collection box, with the angle between the second scraper and the bottom wall of the collection box being less than 45 degrees, and the scraping teeth of the first and second scrapers are staggered. This improves the scraping effect of the first scraper.

[0011] Preferably, a water pump is fixedly connected to the inner bottom wall of the housing, and the two ends of the water pump are respectively connected to a filter pipe and a water outlet pipe. The spiral blades are rotatably connected to the inner wall of the filter pipe. The water flow drives the first scraper to rotate.

[0012] Preferably, a movable plate is provided below the collection box, and insert blocks are provided on both sides of the upper surface of the movable plate. Locking blocks are provided on both sides of the collection box, and a fixing rod is inserted between the locking blocks and the insert blocks. This ensures a closer fit between the movable plate and the collection box.

[0013] Preferably, a controller is provided on the surface of the housing, and the controller is connected to the water pump. This facilitates operation.

[0014] Preferably, the filter screen is attached to the side of the filter box closest to the water pump, and the diameter of the first scraper is equal to the diameter of the filter screen. This ensures more thorough removal of the filter screen.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting a first scraper on one side of the filter screen, and cooperating with the spiral blades to drive the first scraper to rotate when the water pump is pumping water, the debris on the surface of the filter screen is scraped off. At the same time, the second scraper tooth collects the debris scraped off by the first scraper tooth into the collection box, thereby preventing the filter screen from being blocked by large areas of debris such as seaweed and improving the drainage efficiency.

[0017] 2. By installing a movable plate under the collection box, the debris collected in the collection box can be directly cleaned through the movable plate after each drainage operation, avoiding the need to clean the filter screen after each drainage and reducing the workload of the staff.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-5 As shown, the drainage device for water conservancy projects includes: a box 100, with an inlet pipe 110 and an outlet pipe 120 respectively installed at both ends of the box 100, and a filter pipe 130 installed between the inlet pipe 110 and the outlet pipe 120.

[0026] The filtration mechanism 400 includes a filter box 410 fixedly connected between the water inlet pipe 110 and the filter pipe 130. A filter screen 420 is fixedly connected to the inner wall of the filter box 410. A spiral blade 430 is provided inside the filter pipe 130. One end of the spiral blade 430 passes through the filter screen 420 and is fixedly connected to a first scraper 440. A collection box 450 is provided below the filter box 410. A second scraper 441 is fixedly connected inside the collection box 450.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, the filter box 410 is circular and its two sides are connected to the inlet pipe 110 and the filter pipe 130, respectively. The bottom of the filter box 410 is connected to the collection box 450. The second scraper 441 is inclinedly arranged inside the collection box 450. The angle between the second scraper 441 and the bottom wall of the collection box 450 is less than 45 degrees. The scraping teeth of the first scraper 440 and the second scraper 441 are staggered. A water pump 300 is fixedly connected to the bottom wall of the box body 100. The two ends of the water pump 300 are connected to the filter pipe 130 and the outlet pipe 120, respectively. The spiral blade 430 is rotatably connected to the inner wall of the filter pipe 130. A controller 200 is provided on the surface of the box body 100 and is connected to the water pump 300.

[0028] In this embodiment, the water pump 300 mainly consists of a pump body, impeller, shaft, bearings, sealing device, and motor. The pump body is the outer shell of the pump, supporting other components and guiding water flow; the impeller is the core part of the pump, generating water flow power through rotation; the shaft connects the motor and the impeller, transmitting power; the bearings support the shaft and reduce friction; and the sealing device prevents water leakage. The working principle of the water pump 300 is that when the motor drives the impeller to rotate, the high-speed rotation of the impeller draws water from the suction end into the pump body, and accelerates it through the centrifugal force of the impeller, flowing towards the discharge end. During the impeller's rotation, the water flow velocity continuously increases, the pressure gradually rises, and it is eventually discharged into the system. In this way, the water pump 300 achieves water transportation through the processes of suction, pressurization, and discharge.

[0029] The suction end of the water pump 300 needs to be connected to the filter pipe 130, and the discharge end needs to be connected to the drain pipe. This is because the water flow rate in the filter pipe 130 is very fast under the action of the water pump 300, which will drive the spiral blade 430 to rotate rapidly and simultaneously drive the first scraper 440 to rotate rapidly. The width of the first scraper 440 is equal to the distance between the filter screen 420 and the inner wall of the filter box 410. When the first scraper 440 rotates rapidly, the debris will always be confined to the upper part of the collection box 450. At the same time, the bottom end of the second scraper 441 is in contact with the surface of the movable plate 460, preventing the debris from returning to the filter box 410 from below the collection box 450. The filter screen 420 needs to be made of stainless steel or other relatively hard alloy. When the scraper rotates on one side of the filter screen, it will cause the accumulated impurities on the surface of the filter screen to undulate, without causing serious damage to the surface of the filter screen 420.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, a movable plate 460 is provided below the collection box 450. Insert blocks 461 are provided on both sides of the upper surface of the movable plate 460. Locking blocks 451 are provided on both sides of the collection box 450. A fixing rod 462 is inserted between the locking blocks 451 and the insert blocks 461. The filter screen 420 is attached to the side of the filter box 410 closest to the water pump 300. The diameter of the first scraper 440 is equal to the diameter of the filter screen 420. A circular hole is formed on the surface of the insert block 461, and a circular hole is also formed on the surface of the locking block 451. When the insert block 461 is fully inserted into the locking block 451, the two circular holes will align, and the diameter of the fixing rod 462 will be equal to the diameter of the circular hole.

[0031] When using this utility model, the inlet pipe 110 is connected to a flexible hose and placed into the water area that needs to be drained. Then, the water pump 300 is started through the controller 200. The water pump 300 draws water into the device through the inlet pipe 110 and then discharges the water through the outlet pipe 120 from the outlet end to complete the drainage work of the water area.

[0032] When water enters the filter pipe 130, it drives the spiral blade 430 to rotate clockwise. The rotation of the spiral blade 430 drives the first scraper 440 to rotate inside the filter box 410. The water in the inlet pipe 110 passes through the filter screen 420, filtering impurities that accumulate on one side of the filter screen 420. At this time, the first scraper 440 rotates, driving the water to rotate. Impurities will move along the surface of the first scraper 440 towards the inner wall of the filter box 410. When the scraper teeth of the first scraper 440 rotate to the top of the collection box 450, the scraper teeth of the second scraper 441 intersect with the scraper teeth of the first scraper 440, hanging the debris on the first scraper 440 into the collection box 450, preventing impurities from accumulating on the filter screen 420. When a large area of ​​debris such as seaweed is attached to the first scraper teeth, the second scraper teeth will cut it when they intersect with the first scraper teeth to prevent it from sticking to the filter screen 420.

[0033] After the drainage work is completed, simply pull out the fixed rod 462, then remove the movable plate 460 downwards. The impurities in the collection box 450 will fall directly under the action of gravity. After the collection box 450 is cleaned, insert the insert block 461 into the card block 451, and then insert the movable block into the card block 451 directly.

[0034] It should be noted that the water pump 300, spiral blade 430 and filter screen 420 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the water pump 300 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
