Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a self-cleaning water pump. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, water power, efficiency, etc. According to different working principles, it can be divided into volumetric water pumps, vane pumps and other types.

[0003] Water pumps can effectively improve the water delivery efficiency, so that water can be quickly and effectively transported from low to high places to meet various water needs. According to different application scenarios, water pumps can also adjust the flow rate as needed to achieve energy saving. For example, variable frequency water pumps can provide a larger flow rate at the same power and are relatively more energy-saving.

[0004] When the water pump is transporting liquid, if the liquid contains a high concentration of solid matter or chemicals, the solid matter is easy to deposit, and the chemical substances are easy to react with other substances to produce precipitation, which will cause scaling and accumulation inside the water pump, leading to pipe blockage. Improper use or excessive concentration of impurities will also cause impeller blockage, reducing the efficiency of the water pump. Therefore, the water pump needs to be cleaned regularly to extend its service life.

[0005] In the prior art, when cleaning a water pump, the water pump is usually disassembled, and the filter and other parts in the water pump are removed and cleaned, and then assembled again after cleaning. This cleaning method is very cumbersome, and the cleaning process consumes a lot of time. Irregular cleaning will affect the delivery effect and service life of the water pump. Utility Model Content

[0039] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] like Figure 1 to Figure 4As shown, this embodiment proposes a self-cleaning water pump, including a pump body 1, a filter screen 2, a motor 3, a cleaning mechanism, a scraper 4, a cleaning mechanism, a cleaning outlet and a filter screen anti-blocking component. The filter screen 2 is fixedly connected to the pump body 1, the motor 3 is fixedly installed on the pump body 1, the cleaning mechanism is installed in the pump body 1, two scrapers 4 are provided, and the two scrapers 4 are in contact with the filter screen 2. The cleaning mechanism is installed on the pump body 1, the cleaning outlet is opened on the outer wall of the pump body 1, and the filter screen anti-blocking component is installed on the filter screen 2. When the water pump is working, when transporting liquid containing solid matter, Solid matter enters the water pump. At this time, the motor 3 of the water pump starts to work, driving the cleaning mechanism to scrape off the solid sediments on the inner wall of the water pump and the filter 2. There are more sediments on the filter 2, and the sediments on the filter 2 are collected and cleared out by the cleaning mechanism. While the cleaning mechanism is cleaning the filter 2, the filter anti-blocking component is driven by the scraper 4 to start working, and the solid matter blocked in the filter holes of the filter 2 is cleared out. The pump body 1 can be cleaned while the water pump is working. The cleaning efficiency is high, does not affect the water delivery efficiency of the water pump, and better extends the service life of the water pump.

[0041] Furthermore, the cleaning mechanism includes a cleaning plate 5 and a cleaning groove 6. There are two cleaning plates 5. Each scraper 4 is fixedly connected to a cleaning plate 5 at a position where it contacts the filter screen 2. There are two cleaning grooves 6. The two cleaning grooves 6 are fixedly connected to the side walls of the scraper 4. When the water pump is delivering water, the motor 3 is started first. The output end impeller driven by the motor 3 rotates while driving the two scrapers 4 to rotate, driving the cleaning grooves 6 on the scraper 4 to rotate, scraping the solid matter on the filter screen 2 into the cleaning groove 6, and at the same time driving the cleaning plate 5 to scrape the solid matter on the inner wall of the pump body 1, so that the cleaning effect is comprehensive and clean.

[0042] Furthermore, the cleaning mechanism includes a sealing door 7, a handle 8, a disassembly groove and a fixing rod 9. The sealing door 7 is detachably connected to the cleaning outlet, the handle 8 is fixedly connected to the sealing door 7, a plurality of disassembly grooves are provided, and the plurality of disassembly grooves are opened on the outer wall where the scraper 4 contacts the output end of the motor 3. A plurality of fixing rods 9 are provided, and the plurality of fixing rods 9 are fixedly connected to the output end of the motor 3. Each disassembly groove has a fixing rod 9 to cooperate with it. When there are too many solid materials in the cleaning groove, pull the handle 8 to open the sealing door 7, pull out the two scrapers 4, and insert the fixing rod 9 into the disassembly groove after cleaning.

[0043] Furthermore, the filter anti-blocking assembly includes an anti-blocking sliding plate 10 and an inclined block 11. The anti-blocking sliding plate 10 is elastically connected to the filter 2 by a spring 12. The anti-blocking sliding plate 10 is provided with a semi-cylindrical rod 13 that cooperates with the holes on the filter 2. The inclined block 11 is fixedly connected to the anti-blocking sliding plate 10. During the rotation of the scraper 4 driven by the output end of the motor 3, the scraper 4 slides over the inclined surface of the inclined block 11, pushing the anti-blocking sliding plate 10 to slide on the filter 2, and then the scraper 4 passes through the inclined block 11 and resets the anti-blocking sliding plate 10 under the action of the spring 12, so that the semi-cylindrical rod 13 slides back and forth in the filter holes on the filter 2, pushing solid matter out of the filter holes, preventing the filter 2 from being blocked and affecting the water delivery efficiency of the water pump, and there is no need for manual cleaning.

[0044] Preferably, a side wall of the cleaning groove 6 close to the filter screen 2 is set to be an inclined surface, and the inclined surface and the cleaning groove 6 form a shovel shape, which is convenient for shoveling solid matter into the cleaning groove 6.

[0045] More preferably, the radius of the semi-cylinder on the anti-blocking sliding plate 10 is the same as the radius of the filter hole of the filter screen 2. The semi-cylinder can fully stir and eject the solid matter without affecting the liquid transported by the water pump through the filter screen 2.

[0046] In this embodiment, when the water pump is working, the motor 3 drives the scraper 4 to rotate while performing water delivery work, and further drives the cleaning groove 6 and the cleaning plate 5 on the scraper 4 to rotate, so as to clean the inner wall of the pump body 1 and the filter screen 2. The cleaned solid matter enters the cleaning groove 6 or is stirred, and will not accumulate in the pump body 1. At the same time, in the process of the cleaning groove 6 scraping the filter screen 2, the inclined block 11 is pushed up, and the inclined block 11 is pushed up to drive the anti-blocking sliding plate 10 to drive the semi-cylindrical rod 13 to twitch in the filter hole on the filter screen 2, and then reset under the action of the spring 12, so as to prevent the solid matter deposited in the filter hole from clogging the filter hole and affecting the water delivery efficiency.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
