Description

Technical Field

[0001] The utility model relates to the technical field of submersible motors, in particular to a high-insulation motor with a steel cylinder housing suitable for submersible pumps. Background Technique

[0002] Chinese Patent No. CN221531228U discloses an oil-filled submersible motor, which installs a housing and a heat-conducting shell on the surface of the motor, and has a good effect on the heat dissipation of the submersible motor.

[0003] The problem in the above patent is that its heat-conducting shell needs to be adapted to the size of the motor, and the submersible motors used in water pumps in the prior art usually have various different models with different diameters. Therefore, it cannot be well adapted to submersible motors of different sizes, and the scope of application is not wide enough.

[0004] After the submersible motor is installed in the water pump, it needs to be powered by a cable. Since the water pump needs to seal the submersible motor, usually a certain length of the cable is left in a sealed chamber of the water pump and then led out to the outside. Due to the small space, this part usually needs to be bent moderately, which requires the operator to adjust after installing the motor, which is more inconvenient and there is a possibility of over-bending the cable. In a state of long-term over-bending, it may be damaged; moreover, the water pump often vibrates during operation, causing the cable to shake in it.

[0005] Therefore, we propose a high-insulation motor with a steel cylinder housing suitable for submersible pumps to solve the problems raised above.

[0006] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present invention. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Content of the Utility Model

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figure, the relative sizes and proportions of the parts shown in the figure are exaggerated or reduced in size and illustrated. Any size is only exemplary and not limiting.

[0040] Embodiment 1:

[0041] Please refer to Figures 1-4 , a high-insulation motor with a steel cylinder housing suitable for a submersible pump, including: a submersible motor housing 1, a cable 2 is provided at the end face of the submersible motor housing 1, two first collars 3 are sleeved on the submersible motor housing 1, the two first collars 3 are connected by a connecting plate 4, a heat dissipation plate 5 is rotatably connected between the two first collars 3, one end of the heat dissipation plate 5 is in contact with the outer surface of the submersible motor housing 1, the heat dissipation plates 5 are arrayed around the submersible motor housing 1, a fixing piece 7 is further provided on the end face of the first collar 3, the fixing piece 7 is installed on both sides of the contact point between the heat dissipation plate 5 and the submersible motor housing 1, at least three first jacks 8 are provided on the heat dissipation plate 5, a first bolt 9 is provided in one of the first jacks 8, the first bolt 9 is inserted into the heat dissipation plate 5, the heat dissipation plate 5 includes a straight plate 501 and an arc plate 502, the arc of the arc plate 502 is adapted to the submersible motor housing 1, the heat dissipation plate 5 is provided with heat dissipation holes 6, the submersible motor housing 1 is made of steel, a heat conduction layer 16 is filled between the arc plate 502 and the submersible motor housing 1, the heat conduction layer 16 can be materials such as graphene. Since the installed submersible motor housing 1 may have different diameters, after the arc plate 502 contacts the submersible motor housing 1, a gap will be generated between the two, resulting in a reduced contact surface. Filling the gap with a heat conduction material can better transfer heat. The number of fixing pieces 7 is the same as the number of straight plates 501, the fixing pieces 7 are circular arcs, and the connection point between the straight plate 501 and the first collar 3 is the axis.

[0042] Adopting the above technical solution can make the adaptability between the submersible motor housing 1 and the heat dissipation plate 5 better. Since the sizes and models of the submersible motor housings 1 are different, the rotatable heat dissipation plate 5 can be well applied to different submersible motor housings 1.

[0043] Embodiment 2:

[0044] Refer to Figures 1-6, on the basis of Embodiment 1, a protection structure is added at the connection point between the cable 2 and the submersible motor housing 1, which is used to adjust and fix the extending direction of the cable 2 and prevent the cable 2 from being bent excessively. Among them: A second collar 10 is sleeved on the cable 2. There are at least three second collars 10, and two connecting rods 12 are provided between two adjacent second collars 10. The second collar 10 is provided with a groove, and a third collar 11 is provided in the groove. The second collar 10 and the third collar 11 are in transitional fit. The connecting rod 12 and the second collar 10 are rotatably connected by a screw 13. The screw 13 is rod-shaped, and threads are provided on both sides of the middle part. The connection point between the connecting rod 12 and the second collar 10 is located in the middle of the screw 13. A gasket 14 is movably sleeved on the screw 13, and a threaded knob 15 is threadedly sleeved on the screw 13. The connecting rod 12 includes a first movable rod 1201 and a second movable rod 1202. The second movable rod 1202 is inserted into the first movable rod 1201. The first movable rod 1201 is provided with a second jack 1203. A second pin 1204 is provided in one of the second jacks 1203, and the second pin 1204 is also inserted into the first movable rod 1201.

[0045] With the above technical solution, when in use, it is necessary to first determine the bending direction of the cable 2. Since the submersible motor needs to be installed in the housing of the water pump, the cable 2 needs to be bent at the extending end of the submersible motor. First, rotate the third collar 11 closest to the submersible motor housing 1, so that the other second collars 10 rotate. In this way, the connecting rod 12 on the third collar 11 can be rotated. After the angle adjustment is completed, rotate the threaded knob 15 and press it tightly. Then, adjust the other third collars 11 in the same way. Moreover, the extending length of the second movable rod 1202 in the first movable rod 1201 can be adjusted. After the adjustment is completed, the angle of the cable 2 at the connection point can be kept fixed to avoid excessive bending.

[0046] Working principle: When in use, install the first collar 3 on the submersible motor housing 1 and fix it. Rotate the heat dissipation plate 5 so that the arc plate 502 of the heat dissipation plate 5 fits onto the outer surface of the submersible motor housing 1. Utilize the mutual cooperation of the fixing piece 7, the first jack 8 and the first pin 9 to fix the angle of the heat dissipation plate 5, and then fill the gap with the heat conduction layer 16; The cable 2 passes through the second collar 10, and then adjust the distance between each second collar 10 through the connecting rod 12. Rotate the third collar 11 to make the rotation direction of the second collar 10 consistent with the direction in which the cable 2 needs to be bent, and then rotate. After adjustment, rotate the threaded knob 15 to keep its angle fixed.
