Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically, to an active cooling starter motor. Background Technology

[0002] In the field of water conservancy construction, a water depth measuring device is a device used to measure the depth of water bodies, mainly for measuring the depth of water bodies used in water conservancy projects to widen and deepen river channels. An existing motor with publication number CN219107179U includes a motor housing, a stator fixedly disposed within the motor housing, and a rotor rotatably disposed within the motor housing. The motor housing includes a shell and an end cover connected to each other. The shell has a cylindrical structure with at least one open end. The end cover is located at at least one open end of the shell. The rotor's shaft is rotatably connected to the end cover. The end cover has a first joint portion. The at least one open end of the shell extends radially outward to form a second joint portion. The first and second joint portions overlap. One of the first and second joint portions forms several grooves, and the other forms several protrusions. Each protrusion is placed within a corresponding groove and transitionally engages with the groove radially, achieving relative radial positioning between the two. After assembly, the rotor and stator exhibit good concentricity.

[0003] However, in the above solution, since a lot of heat will accumulate inside the motor housing when the motor starts, passive heat dissipation alone will result in insufficient heat dissipation, which may lead to the inability to dissipate the heat inside the motor in time, causing the motor temperature to rise and affecting the normal operation and lifespan of the motor. Utility Model Content

[0004] The main purpose of this utility model is to provide an active heat dissipation starter motor, which can effectively solve the problem in the background art where a lot of heat accumulates inside the motor housing when the motor starts. If only passive heat dissipation is used, the heat dissipation effect will be insufficient, which may lead to the inability to dissipate the heat inside the motor in time, causing the motor temperature to rise and affecting the normal operation and life of the motor.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An active cooling starter motor includes a housing, and a support frame is fixedly installed inside the housing;

[0007] A front cover is fixedly installed at one end of the outer shell, and a rear cover is fixedly installed at the other end of the outer shell. A rotating shaft is rotatably installed between the front cover and the rear cover.

[0008] A heat dissipation component for heat dissipation is provided on one side of the rear end cover, and a number of air inlets are provided through the other side surface of the rear end cover. A number of exhaust grooves are provided through the inner wall surface of the outer shell.

[0009] The rotor is fitted onto the shaft body, and the stator is fixedly installed inside the support frame.

[0010] Preferably, the heat dissipation assembly includes several slide rods, each slide rod being slidably disposed through one side of the rear end cover, and each slide rod having a common annular frame at one end, with a circular plate rotatably mounted inside the annular frame via bearings, and several blades fixedly mounted on the body of the circular plate.

[0011] Preferably, a first friction disc is fitted onto the side of the rotating shaft near the blade;

[0012] The second friction disc is fixedly installed on the side of the circular plate near the first friction disc.

[0013] Preferably, a lead screw is rotatably mounted on one side of the rear end cover, and a movable plate is fixedly mounted on the other end of each slide rod, with the movable plate threaded onto one side of the lead screw body.

[0014] Preferably, each of the slide rods has a limiting hole on one end surface, a limiting block is fixedly installed in each limiting hole, a slide column is slidably disposed through one side of each limiting block, one end of each slide column is fixedly connected to the ring frame, a positioning block is fixedly installed at the other end of each slide column, and a spring is provided on one side of the inner wall of each limiting hole.

[0015] Preferably, each of the slide bars is fitted with a baffle, and a number of right-angle frames are slidably arranged through one end of the support frame, with a cover plate fitted at one end of each right-angle frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) When the motor starts, the shaft rotates under the cooperation of the stator and the rotor. After the motor starts, the staff controls the circular plate to rotate, so that the circular plate drives the blades to rotate. Under the guiding effect generated by the rotation of the blades, the external airflow enters the inside of the casing through the air inlet and then exits from the exhaust groove, so that the heat accumulated inside the casing is discharged in time, thereby avoiding the motor temperature from rising, ensuring the normal operation of the motor, and improving the motor life.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] like Figures 1-4 As shown, an active cooling starter motor includes a housing 1, and a support frame 2 is fixedly installed inside the housing 1.

[0025] A front cover 3 is fixedly installed at one end of the outer shell 1, and a rear cover 4 is fixedly installed at the other end of the outer shell 1. A rotating shaft 5 is rotatably installed between the front cover 3 and the rear cover 4.

[0026] A heat dissipation component 6 for heat dissipation is provided on one side of the rear cover 4, and several air inlets 19 are provided through the other side of the rear cover 4, and several exhaust grooves 20 are provided through the inner wall surface of the outer shell 1.

[0027] The rotor 501 is mounted on the shaft body of the rotating shaft 5, and the stator 201 is fixedly installed inside the support frame 2.

[0028] The heat dissipation assembly 6 includes several slide rods 601, each slide rod 601 is slidably disposed on one side of the rear end cover 4, and each slide rod 601 has a common ring frame 602 at one end. A circular plate 604 is rotatably mounted inside the ring frame 602 via a bearing 603, and several blades 605 are fixedly mounted on the body of the circular plate 604.

[0029] When the motor starts, the shaft 5 rotates under the combined action of the stator 201 and the rotor 501. After the motor starts, the operator controls the circular plate 604 to rotate, which in turn drives the blades 605 to rotate. Under the guiding effect generated by the rotation of the blades 605, the external airflow enters the interior of the outer casing 1 through the air inlet 19 and then exits from the exhaust groove 20. This allows the heat accumulated inside the outer casing 1 to be dissipated in a timely manner, preventing the motor temperature from rising, ensuring the normal operation of the motor, and extending the motor's lifespan.

[0030] In another embodiment of the present invention, a first friction disc 7 is sleeved on the side of the shaft body of the rotating shaft 5 near the blade 605;

[0031] A second friction disc 8 is fixedly installed on the side of the circular plate 604 near the first friction disc 7.

[0032] A lead screw 9 is rotatably mounted on one side of the rear end cover 4, and a movable plate 10 is fixedly mounted on the other end of each slide rod 601. The movable plate 10 is threaded onto one side of the lead screw 9.

[0033] When the motor needs cooling, the operator rotates the lead screw 9, causing it to move the movable plate 10 through the threaded screw. This causes the movable plate 10 to move the slide rod 601 and the second friction disc 8 closer to the first friction disc 7. Subsequently, under the combined action of the first friction disc 7 and the second friction disc 8, the blade 605 rotates with the circular plate 604. When the working environment temperature is low and cooling is not required, the operator rotates the lead screw 9 in the opposite direction, causing the blade 605 to stop rotating. This allows the operator to flexibly adjust the start and stop of the blade 605 as needed.

[0034] In another embodiment of this utility model, a limiting hole 11 is provided on one end surface of each slide rod 601, a limiting block 12 is fixedly installed in each limiting hole 11, a slide post 13 is slidably arranged through one side of each limiting block 12, one end of each slide post 13 is fixedly connected to the ring frame 602, a positioning block 14 is fixedly installed at the other end of each slide post 13, and a spring 15 is provided on one side of the inner wall of each limiting hole 11.

[0035] When the first friction disk 7 and the second friction disk 8 are in contact, the spring 15 is compressed. Under the pushing action of the compressed spring 15, the first friction disk 7 and the second friction disk 8 are tightly in contact, which increases the friction force when in contact, so that the second friction disk 8 can drive the first friction disk 7 to rotate more effectively.

[0036] In another embodiment of this utility model, each slide rod 601 is fitted with a baffle 16, and a number of right-angle frames 17 are slidably arranged through one end of the support frame 2, with a cover plate 18 fitted at one end of each right-angle frame 17.

[0037] When the slide bar 601 moves and the first friction disc 7 separates from the second friction disc 8, the cover plate 18 can cover the exhaust groove 20 and the baffle 16 can cover the air inlet 19 to prevent external cold air from entering the motor and causing the internal components of the motor to malfunction due to low temperature.

[0038] The working principle of this type of active cooling starter motor:

[0039] When in use, when the motor starts, the shaft 5 rotates under the cooperation of the stator 201 and the rotor 501. After the motor starts, the operator controls the circular plate 604 to rotate, which causes the circular plate 604 to drive the blades 605 to rotate. Under the guiding effect generated by the rotation of the blades 605, the external airflow enters the interior of the outer casing 1 through the air inlet 19 and then exits from the exhaust groove 20. This allows the heat accumulated inside the outer casing 1 to be discharged in time, preventing the motor temperature from rising, ensuring the normal operation of the motor, and extending the motor life.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
