Description

Technical Field

[0001] The invention relates to the technical field of water pumps, in particular to a water pump with a crushing function and a crushing method thereof. 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, etc. 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 positive displacement water pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between the rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps.

[0003] Most existing water pumps are used to extract or transport water and liquid materials. In addition to being fixedly installed in factories for use, they are also usually used for outdoor pumping operations. However, current water pumps still have obvious defects when used outdoors, such as: When a water pump is used outdoors, it needs to be connected to a long water pipe, and one end of the water pipe is inserted into deeper water. Therefore, when the water pump is pumping water, it is easy to suck weeds and soil on the bottom of the water into the pump body, which will cause the internal impeller to be entangled and collided, easily causing damage. In addition, the water pump is usually connected to the drive motor. If one of the devices needs to be repaired separately, it cannot be quickly disassembled, which is inconvenient for subsequent maintenance.

[0004] Therefore, a water pump with a breaking function that can be easily used is designed to solve this type of defect. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a water pump with a breaking function and a breaking method thereof, which solves the problem that the prior water pump is easily entangled with aquatic plants and damaged.

[0009] Preferably, the top of the load-bearing base plate is fixedly connected to a positioning slide frame via a fixing plate, and the top of the load-bearing base plate and the front of the positioning slide frame are fixedly connected to a telescopic slide frame via a fixing plate, the rear portions of the positioning slide frame and the telescopic slide frame are both provided with limiting sockets that extend through to the front, and a U-shaped plug plate that cooperates with the inclined plug plate is slidably installed on the inner side of the telescopic slide frame.

[0010] Preferably, the breaking and pumping mechanism includes a sliding seat, and the sliding seat is slidably installed on the inner side of the positioning slide frame, and positioning holes used in conjunction with the limit sockets and the inclined plug plates are provided on both sides of the sliding seat, and the top of the positioning hole is fixedly connected to the outer frame of the pump body through a fixing plate, and the surface of the outer frame of the pump body is fixedly connected to an extension circular tube through an opening, and an arc groove guide opening is provided on the front part of the inner wall of the extension circular tube, and a plurality of arc groove guide openings are provided.

[0011] Preferably, a filter insert is provided on the inner side of the extended circular tube, a limit stop ring used in conjunction with the filter insert is fixedly connected to the rear portion of the inner wall of the extended circular tube, a limit arc block used in conjunction with the arc groove guide is fixedly connected to the outer periphery of the filter insert, an outer insert used in conjunction with the extended circular tube is fixedly connected to the surface of the filter insert, and a locking socket used in conjunction with the U-shaped plug plate is provided on the rear side of the bottom of the outer insert.

[0012] Preferably, the rear part of the inner cavity of the filter insert is rotatably connected to a driven rotating rod through an opening, a crushing blade is fixedly connected to the surface of the driven rotating rod, a first polygonal recess is fixedly connected to the rear end of the driven rotating rod, and the rear part of the inner cavity of the outer frame of the pump body is rotatably connected to an inner polygonal rotating drum through an opening, and an impeller is fixedly connected to the surface of the inner polygonal rotating drum.

[0013] Preferably, a second polygonal rod used in conjunction with the first polygonal recessed block is slidably installed on the inner side of the inner polygonal rotating cylinder, and reset guide rods are fixedly connected to both sides and the upper and lower parts of the rear part of the outer frame of the pump body, and a translation sleeve used in conjunction with the inner polygonal rotating cylinder is fixedly connected between the surfaces of the four reset guide rods, and the translation sleeve is fixedly connected to the rear end of the second polygonal rod, a spring is provided on the surface of the reset guide rod, and the rear part of the translation sleeve is rotatably connected to the second polygonal recessed block used in conjunction with the first polygonal rod through an opening.

[0014] The present invention also discloses a method for using a water pump with a crushing function, which specifically comprises the following steps: S1. Before use, insert the outer frame of the pump body into the interior of the positioning slide frame through the sliding seat, and make the positioning port and the limiting socket dock and overlap, then insert the filter cartridge into the inner side of the extended round tube through the docking of the limiting arc block and the arc groove guide port. At this time, the locking socket is located directly above the U-shaped plug plate. After the installation is completed, rotate the threaded rod to use the limit of the guide slide groove to push the guide slide frame and the motor to move forward slowly. During the forward movement of the motor, the first polygonal rod will be inserted into the inner side of the second polygonal concave block for docking, and the rotating rod will squeeze the translation sleeve at the same time. Under the limit of the reset guide rod, the translation sleeve is inserted into the inner side of the inner polygonal rotating cylinder, and at the same time, the front end of the second polygonal rod is also pushed and inserted into the interior of the first polygonal recessed block. At this time, the driven rotating rod uses the second polygonal rod to form a whole with the first polygonal rod. After the motor is completely moved to the front, the front end of the inclined plug plate will also pass through the positioning port and the limiting plug port in turn and extend to the front of the telescopic sliding frame, and the inclined plug plate squeezes the U-shaped plug plate to rise and insert into the inner side of the locking plug port. At this time, the filter plug cylinder and the outer frame of the pump body are fixed, and then go to step S2.

[0015] S2. After the installation is completed, the outer insert is connected to the water outlet and the water inlet of the outer frame of the pump body, and then the motor is started to use the rotating rod and the first polygonal rod to drive the second polygonal recessed block, the inner polygonal rotating cylinder and the second polygonal rod to rotate. At the same time, since the second polygonal rod is connected to the first polygonal recessed block, the impeller and the crushing blade rotate synchronously. At this time, the rotation of the impeller forms a negative pressure to suck water into the filter insert. If there are impurities such as water plants in the water, they will be crushed by the crushing blade and filtered and blocked by the filter insert. The filtered water enters the inner frame of the pump body and then flows out from the water outlet.

[0016] S3. After the work is completed, turn off the motor, then rotate the threaded rod in the opposite direction and use the limit of the guide slide groove to drive the motor to move backward. At this time, the first polygonal rod will be pulled out from the inner side of the second polygonal recessed block. At the same time, the rotating rod no longer presses the translation sleeve. At this time, the translation sleeve pushes the second polygonal rod to be pulled out from the inner side of the first polygonal recessed block through the elastic force of the spring. At the same time, the inclined plug plate also moves backward and is pulled out from the inside of the positioning slide frame. At this time, the U-shaped plug plate loses the extrusion and automatically falls and separates from the inner side of the locking socket. At the same time, the sliding seat also loses the limit. Then the pump body outer frame and the filter insert are disassembled in turn for maintenance.

[0017] Beneficial Effects The present invention provides a water pump with a crushing function and a crushing method thereof. Compared with the existing technology, it has the following beneficial effects: (1) The water pump with crushing function and the crushing method thereof use a driving locking mechanism and a crushing pumping mechanism in combination. The arrangement of the two mechanisms can utilize the linkage between the structures to dynamically connect the motor with the outer frame of the pump body. At the same time, the outer frame of the pump body and the filter insert are fixed, which is convenient for installation and disassembly, ensuring the convenience of subsequent maintenance by the staff. At the same time, the crushing blade rotating during driving can crush impurities such as water plants to avoid damage to the impeller, effectively improving the service life of the equipment.

[0018] (2) The water pump with crushing function and the crushing method thereof are characterized by installing a filter insert on the inner side of the extended circular tube, and installing a crushing blade on the inner side of the filter insert by using a driven rotating rod, and using the first polygonal concave block and the second polygonal rod. The arrangement of these structures can utilize the docking of the second polygonal rod to drive the crushing blade to rotate so as to crush the impurities in the water. At the same time, the filter insert itself further filters the crushed impurities, ensuring that the impeller will not be affected when rotating, improving the stability during operation, and satisfying the current use.

[0019] (3) The water pump with crushing function and the crushing method thereof are used by installing an inclined plug plate on the surface of the threaded groove plate, and using it in combination with a threaded rod, a limit socket and a U-shaped plug plate. The arrangement of these structures can utilize the thrust generated when the threaded rod rotates to allow the motor and the impeller to be dynamically connected. At the same time, the inclined plug plate passes through the positioning hole and the limit socket to not only fix the outer frame of the pump body, but also squeezes the U-shaped plug plate to insert it into the locking socket to fix the filter cartridge, making it quick and convenient to install, and can also ensure the stability of the equipment. At the same time, it is also convenient for subsequent separate disassembly and replacement, without the need for cumbersome maintenance processes, thereby improving work efficiency.

[0026] The present invention also discloses a method for using a water pump with a crushing function, which specifically comprises the following steps: S1. Before use, first insert the pump body frame 203 into the interior of the positioning slide frame 109 through the sliding seat 201, and make the positioning port 202 and the limiting socket 110 dock and overlap, then insert the filter cartridge 206 into the inner side of the extension tube 204 through the docking of the limiting arc block 207 and the arc groove guide port 205.

At this time, the first polygonal rod (106) is pulled out from the inner side of the second polygonal recess (219), and the rotating rod (105) no longer presses the translation sleeve (217). At this time, the translation sleeve (217) pushes the second polygonal rod (215) to be pulled out from the inner side of the first polygonal recess (212) through the elastic force of the spring (218). At the same time, the inclined plug plate (113) is also moved backward and pulled out from the inside of the positioning slide frame (109). At this time, the U-shaped plug plate (111) loses the squeezing force and automatically falls down and separates from the inner side of the locking socket (209). At the same time, the sliding seat (201) also loses the limit. Then, the pump body outer frame (203) and the filter insert (206) are disassembled in sequence for maintenance.
