Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, and particularly relates to a device for fixing a motor. Background Art

[0002] A water pump is an important device for lifting water from deep wells. During use, the entire unit works underwater. Before starting the pump, the suction pipe and the pump must be filled with liquid. After starting the pump, the impeller rotates at high speed, and the liquid therein rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots outwards. The speed of the ejected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Then, it flows out from the pump outlet and the discharge pipe. At this time, due to the liquid being thrown towards the surrounding at the center of the blade, a vacuum low-pressure area without air or liquid is formed. Under the action of the atmospheric pressure on the liquid pool surface, the liquid in the liquid pool flows into the pump through the suction pipe. In this way, the liquid is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.

[0003] The application publication number is CN110454409A, which discloses a submersible pump for wells. Combining its specification and drawings, in its solution, the pump body includes a canned motor and a lower impeller group. The output shaft of the canned motor extends out of the lower shaft part from the upper part of the canned motor, and the lower impeller group is installed on the lower shaft part. The canned motor is fixed on the inner wall of the pump body placement cavity through the installation part. However, the connection between the installation part and the pump body placement cavity is equivalent to an integral connection, which is inconvenient for disassembling and assembling the upper impeller group and the lower impeller group, bringing inconvenience to installation or disassembly. Summary of the Invention

[0004] The utility model mainly aims at the problems existing in the disassembly and assembly of the above water pump, and invents a device for fixing a motor. For fixing the middle position of the outer shell of the driving motor during the working process of the water pump, only need to use a screwdriver to hold the cross groove on the surface of the metal screw and rotate it, so that the conical boss squeezes the inclined surface of the slider until the telescopic slider slides to the right inside the telescopic chute until the first arc surface firmly fits the outer shell of the driving motor. When disassembling, only need to rotate the metal screw; since the telescopic support block is arranged on the surface of the second limit block, the gap between the second limit block and the outer shell of the driving motor does not allow the telescopic slider to easily fall off.

[0021] The following further describes the utility model with reference to the embodiments shown in the drawings:

[0022] As Figures 1 to 5As shown in the figure, a device for fixing a motor includes a water pump body 1 and a driving component 2 arranged inside the water pump body 1. The water pump body 1 includes a water pump housing 12, a housing base 13, and a diversion housing 14. The housing base 13 is arranged at one end of the water pump housing 12, and several diversion housings 14 are provided at the other end of the water pump housing 12. Several diversion impellers 3 are arranged inside the water pump body 1. The driving component 2 can drive the diversion impellers 3 to rotate. A housing upper cover 5 is arranged on the top of the water pump housing 12. Several flange plates 6 are provided on the top outer wall of the housing upper cover 5 and the water pump housing 12. Each diversion housing 14 is pressed by a fixing rod 61 arranged inside each flange plate 6. Several first inclined diversion plates 141 allowing water to pass through are arranged inside each diversion housing 14. Several second inclined diversion plates 31 allowing water to pass through are arranged inside each diversion impeller 3. The driving component 2 includes a driving motor 21 and a driving rotating shaft 22. The driving motor 21 is arranged inside the water pump body 1. The driving rotating shaft 22 is connected to the driving motor 21 at the top. Each driving rotating shaft 22 is connected to a diversion impeller 3. After such a setting, the driving motor 21 can drive the driving rotating shaft 22 to rotate. When the driving rotating shaft 22 rotates, each diversion impeller 3 will also rotate. When the diversion impeller 3 rotates, water will flow in from the second inclined diversion plate 31 and be thrown upward by centrifugal force onto the first inclined diversion plate 141 inside the diversion housing 14, and then continue to be thrown upward under the action of the flow channel formed by the first inclined diversion plate 141 into the inside of the housing upper cover 5. If a pipeline is connected to the outside of the housing upper cover 5, then the water can flow out normally.

[0023] In this embodiment, several first limiting blocks 11 are provided inside the water pump body 1. An expansion limiting component 4 for clamping the outside of the driving component 2 is provided between adjacent first limiting blocks 11. The expansion limiting component 4 as a whole can be elongated or shortened. Specifically, the expansion limiting component 4 includes an expansion support block 41 and an expansion slider 42. An expansion sliding groove 411 is provided inside the expansion support block 41. An expansion slider 42 that can squeeze and fix the outer shell of the driving motor 21 is slidably provided inside the expansion sliding groove 411. One end of the expansion support block 41 is provided with a first arc surface 412 for fitting the outer shell of the driving motor 21. One end of the expansion slider 42 is provided with a second arc surface 422 for fitting the inside of the water pump body 1. A threaded hole is provided on the surface of the expansion support block 41. A metal screw 43 is threadedly connected inside the threaded hole. One end of the expansion slider 42 is provided with a slider inclined surface 421. One end of the metal screw 43 close to the expansion sliding groove 411 is provided with a conical boss 431 for squeezing the slider inclined surface 421 to make the expansion slider 42 slide left and right. It should be noted that several first limiting blocks 11 are provided at the bottom of the water pump housing 12. Several second limiting blocks 15 are also provided at the bottom of the water pump housing 12. The expansion support block 41 is provided on the surface of the second limiting block 15. The length of the second limiting block 15 is not greater than the length of the expansion slider 42. After such a setting, both ends of the driving motor 21 are fixed to the top and bottom of the water pump housing 12. For fixing the position of the middle and lower part of the driving motor 21, during installation, the housing base 13 needs to be removed first. Then, use a screwdriver to hold the cross slot on the surface of the metal screw 43, and then rotate the metal screw 43. In this way, the conical boss 431 at the end of the metal screw 43 can continuously squeeze the slider inclined surface 421. In this way, the expansion slider 42 will slide to the right inside the expansion sliding groove 411 until the second arc surface 422 firmly fits the inside of the water pump housing 12. The first arc surface 412 at one end of the expansion support block 41 firmly fits the outer shell of the driving motor 21, and even if the expansion slider 42 does not fit the outer shell of the driving motor 21, it will not fall off. This is because the expansion support block 41 is provided on the surface of the second limiting block 15, and the gap between the second limiting block 15 and the outer shell of the driving motor 21 does not allow the expansion support block 41 to fall off easily, making the overhaul and disassembly more convenient.

[0024] Working principle and usage method of the utility model:

[0025] For the working principle of the entire water pump, the driving motor 21 can drive the driving rotating shaft 22 to rotate. When the driving rotating shaft 22 rotates, each flow guiding impeller 3 will also rotate. When the flow guiding impeller 3 rotates, water will flow in from the second inclined flow guiding plate 31 and be thrown upward under the action of centrifugal force onto the first inclined flow guiding plate 141 inside the flow guiding housing 14, and then continue to be thrown upward under the action of the flow path formed by the first inclined flow guiding plate 141 into the inside of the upper housing cover 5 of the housing. If a pipeline is connected to the outside of the upper housing cover 5, then the water can flow out normally;

[0026] For the middle position of the housing that fixes the driving motor 21, during installation, first, the housing base 13 needs to be removed. Then, use a screwdriver to hold the cross slot on the surface of the metal screw 43, and then rotate the metal screw 43. In this way, the tapered boss 431 at the end of the metal screw 43 can continuously squeeze the inclined surface of the slider 421, so that the telescopic slider 42 will slide to the right inside the telescopic chute 411 until the second arc surface 422 firmly fits inside the water pump housing 12. One end of the telescopic support block 41, the first arc surface 412, firmly fits the housing of the driving motor 21, and even if the telescopic slider 42 does not fit the housing of the driving motor 21, it will not fall off. This is because the telescopic support block 41 is arranged on the surface of the second limiting block 15, and the gap between the second limiting block 15 and the housing of the driving motor 21 does not allow the telescopic support block 41 to fall off easily, making the maintenance and disassembly more convenient.
