Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor heat dissipation, in particular to a drive-controlled negative pressure heat dissipation motor. BACKGROUND

[0002] In today's industrial and technological fields, electric motors, as an important power equipment, are widely used in various occasions. However, with the continuous improvement of motor power and the extension of running time, the heat problem of electric motors is increasingly prominent. High temperature can affect the performance and service life of electric motors, and even cause motor failure and damage. Negative pressure heat dissipation, as a new type of heat dissipation method, has the advantages of high heat dissipation efficiency and strong adaptability. By installing a fan inside or outside the motor, the fan rotates to generate airflow and form negative pressure, achieving negative pressure heat dissipation. The fan speed can be adjusted in real time according to the running state and temperature change of the motor, so as to achieve more accurate and effective heat dissipation.

[0003] During the operation of the fan, air from the outside world is often sucked in, and the air often contains a large amount of dust particles. These dusts are carried into the fan blades with the airflow, and the dusts cover the fan blades, affecting the aerodynamic characteristics of the fan blades and reducing the airflow efficiency of the fan, thereby reducing the heat dissipation effect. The reduced heat dissipation efficiency leads to overheating of the motor or related equipment, affecting its normal operation. The accumulation of dust will generate more noise when the fan is running, because the dust particles will make the fan blades unbalanced, causing the fan to vibrate when it is running. In addition, the fan blades are fixedly connected to the shaft by screws, and the fan usually needs to use a screwdriver or other tools for disassembly, which takes a long time and requires a lot of time and effort.

[0004] Therefore, the present application provides a drive-controlled negative pressure heat dissipation motor to improve the shortcomings of the traditional technology. The dust on the fan blades can be automatically cleaned by the mechanism, ensuring the normal operation of the fan and the good heat dissipation of the equipment. The fan blades can be replaced by simply moving when they are damaged. SUMMARY

[0005] In view of the shortcomings of the prior art, the present application provides a drive-controlled negative pressure heat dissipation motor to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present application is implemented by the following technical scheme: a drive-controlled negative pressure heat dissipation motor, comprising a motor body, a ventilation and heat dissipation plate fixedly connected to the outside of the motor body, a shaft rotatably connected to the inside of the motor body, a fan blade provided on the outside of the shaft, an auxiliary assembly provided in the inside of the motor body for scraping the dust on the surface of the fan blade, and an easy-to-disassemble assembly provided on the outside of the shaft for facilitating disassembly and replacement of the fan blade.

[0007] As preferred, the auxiliary assembly comprises an assembly shell, the outer side of the assembly shell is through and fixedly connected with the inner side of the motor body, the end of the assembly shell away from the motor body is through and slidably connected with an auxiliary column, the inner side of the assembly shell is fixedly connected with a fixed plate, the inner side of the fixed plate is symmetrically slidably connected with a convex plate, the inner side of the convex plate is slidably connected with a slide column, the inner side of the convex plate is fixedly connected with a first auxiliary block and a second auxiliary block, the outer surface of the convex plate is rotatably connected with an irregular rotating block, the outer surface of the irregular rotating block is rotatably connected with a first cylinder, the bottom of the irregular rotating block and the outer surface of the convex plate are fixedly connected with a first spring, the outer surface of the slide column is fixedly connected with a moving block, the outer surface of the convex plate is provided with a sliding groove, the moving block is slidably arranged in the sliding groove, the inner side of the slide column away from the auxiliary column is slidably connected with an auxiliary plate, the inner wall of the slide column away from the auxiliary column is fixedly connected with a second cylinder, the bottom of the auxiliary plate is fixedly connected with a connecting plate, the inner side of the connecting plate is slidably connected with a scraper, the scraper and the inner wall of the connecting plate are fixedly connected with a second spring.

[0008] As preferred, the end of the auxiliary column close to the fixed plate is fixedly connected with the outer surface of the convex plate.

[0009] As preferred, the outer surface of the slide column is provided with a circular hole, the outer surface of the convex plate is provided with a through groove, the size of the first cylinder is adapted to the size of the circular hole and the through groove, and the first cylinder is slidably arranged in the through groove and the circular hole.

[0010] As preferred, the outer surface of the auxiliary plate is provided with an inclined groove, and the second cylinder is slidably arranged in the inclined groove.

[0011] As preferred, the detachable assembly comprises a spring sheet, the end of the spring sheet away from the rotating shaft is fixedly connected with the outer surface of the fan blade, the end of the spring sheet away from the fan blade is fixedly connected with a clamping block, the outer surface of the rotating shaft is fixedly connected with a mounting groove, the inner wall of the mounting groove is fixedly connected with a rubber pad, the outer surface of the end of the mounting groove located outside the rotating shaft is fixedly connected with a blocking plate, and the outer surface of the blocking plate is provided with a clamping groove.

[0012] As preferred, the spring sheet is in V shape.

[0013] As preferred, the size of the clamping block is adapted to the size of the clamping groove.

[0014] The present application has the following advantages:

[0015] 1、Through the cooperation of the auxiliary assembly, the convex plate drives the irregular rotating block to move and touch the first auxiliary block, which makes the irregular rotating block extrude the first spring and drive the first cylinder to move upward, so that the first auxiliary block moves the moving block to drive the slide to move, and the slide moves to make the scraper move and tightly contact the fan blades. When the convex plate moves back, the scraper cleans the dust on the surface of the fan blades. After cleaning, the slide moves to retract the scraper when the irregular rotating block is extruded by the second auxiliary block, realizing the automatic pop-up and retraction of the scraper. The dust on both sides of the fan blades can be scraped at the same time, saving cleaning time and effort, simplifying the cleaning steps and improving the cleaning efficiency. Cleaning both sides can maintain the balance of the fan, reducing the imbalance caused by single-sided cleaning. By using one-way cleaning for fan blades instead of back and forth cleaning, the already cleaned area can be avoided from being contaminated by the uncleaned area, reducing the possibility of such secondary pollution.

[0016] 2、The dust on both sides of the fan blades can be scraped by the two scrapers, which can reduce the resistance of the fan blades, improve the fan speed, enhance the heat dissipation effect, and make the fan work more efficiently, reduce energy consumption, and reduce noise. The use of the second spring allows the scraper to have a certain buffering effect when it comes into contact with the fan blades, reducing the risk of scratching or damaging the surface of the fan blades. This helps to maintain the integrity and performance of the fan blades and prolongs the service life of the fan. The second spring can make the scraping force more evenly distributed on the surface of the fan blades, avoiding local overloading that can cause deformation or damage to the fan blades. At the same time, uniform stress can also help improve the dust removal effect and ensure that the fan blades are thoroughly cleaned.

[0017] 3、Through the cooperation of the easy-to-dismount assembly, the fan blades can be easily removed and replaced by simply moving them when they are damaged. This design makes it very simple and quick to replace the fan blades without the need for complex tools. Quickly replacing the fan blades can reduce downtime caused by damaged fan blades and improve work efficiency. The spring sheet is in the shape of a V, which can provide a large and uniform elastic restoring force to ensure that the spring sheet can stably perform the functions of clamping or releasing during operation. Its unique shape design not only provides elastic function but also occupies relatively small space, making it suitable for devices with limited space. The rubber pad can increase the friction force on the surface of the spring sheet, thereby improving the gripping force of the easy-to-dismount assembly and preventing the fan blades from falling off during movement or vibration. It has good elasticity and buffering performance, which can absorb part of the impact force when the spring sheet is in use, reducing damage caused by impact or vibration.

[0039] The following is the whole working process and working principle of the above embodiment:

[0040] In the initial state, the first spring 510 is compressed, the irregular rotating block 59 is located below the second auxiliary block 57, the first cylinder 58 is not located in the round hole of the slide column 55, the second cylinder 513 is located at the bottom end of the inclined groove of the auxiliary plate 512, the second spring 516 is not compressed, the moving block 511 is blocked by the wider end of the second auxiliary block 57, the moving block 511 is located at the end of the slide groove of the convex plate 54 away from the auxiliary column 52, the spring sheet 61 is located in the rubber pad 64, and one end of the spring sheet 61 is located below the blocking plate 65.

[0041] Firstly, when the fan blade 4 surface has dust cover, the operator starts the air cylinder when the fan stops working, the air cylinder stretches and drives the auxiliary column 52 to move to the direction close to the fan blade 4, the auxiliary column 52 drives the two convex plates 54 to slide in the fixed plate 53, the convex plate 54 moves to the direction close to the fan blade 4, the convex plate 54 drives the slide column 55, the first cylinder 58, the moving block 511, the irregular rotating block 59 and the first spring 510 to move, when the first cylinder 58, the irregular rotating block 59 and the first spring 510 move away from the lower side of the second auxiliary block 57, the first spring 510 resets and drives the irregular rotating block 59 to move upwardly, since the outer surface of the slide column 55 is provided with a circular hole and the outer surface of the convex plate 54 is provided with a through groove, the irregular rotating block 59 drives the first cylinder 58 to move to the circular hole in the slide column 55, the first cylinder 58 slides in the through groove, the first cylinder 58 clamps the slide column 55 to prevent the slide column 55 from moving, since the width of the first auxiliary block 56 is larger than the width of the second auxiliary block 57, the moving block 511 can slide under the second auxiliary block 57, the first auxiliary block 56 can block the moving block 511, the first auxiliary block 56 and the second auxiliary block 57 can press the irregular rotating block 59, the end of the second auxiliary block 57 away from the first auxiliary block 56 has the same width as the first auxiliary block 56 and can also block the moving block 511, when the first cylinder 58, the irregular rotating block 59 and the first spring 510 move to the lower side of the first auxiliary block 56, the first auxiliary block 56 presses the irregular rotating block 59 to deflect and press the first spring 510 to deform, since the irregular rotating block 59 is rotationally connected with the first cylinder 58, the irregular rotating block 59 drives the first cylinder 58 to move upwardly when it moves to deflect, the slide column 55 is not clamped, when the moving block 511 touches the first auxiliary block 56, the moving block 511 blocks the first auxiliary block 56, the convex plate 54 moves to drive the slide column 55 to move, the slide column 55 drives the second cylinder 513 to move, the second cylinder 513 slides in the inclined groove of the auxiliary plate 512 to drive the auxiliary plate 512 to move downwardly, the auxiliary plate 512 drives the connecting plate 514 to move, the connecting plate 514 drives the scraper 515 and the second spring 516 to move, when the second cylinder 513 slides at the top end of the inclined groove, the scraper 515 is located on the surface of the end of the fan blade 4 close to the rotating shaft 3, the scraper 515 contacts with the surface of the fan blade 4 to press the second spring 516 to deform, at this time, the air cylinder starts to contract to drive the auxiliary column 52 to move away from the rotating shaft 3, the auxiliary column 52 drives the convex plate 54 to move, the convex plate 54 drives the slide column 55 to move, the slide column 55 drives the auxiliary plate 512 and the connecting plate 514 to move, the connecting plate 514 drives the scraper 515 to move, the scraper 515 scrapes the dust on the surface of the fan blade 4, the dust on both sides of the fan blade 4 can be scraped by the two scrapers 515, which can reduce the resistance of the fan blade 4, improve the rotating speed of the fan, enhance the heat dissipation effect, and make the fan work more efficiently,The energy consumption is reduced, the noise generation is reduced, the use of the second spring 516 enables the scraper 515 to have a certain buffering effect when contacting the fan blade, reducing the risk of scratching or damaging the surface of the fan blade 4, which helps to maintain the integrity and performance of the fan blade 4 and prolong the service life of the fan. The second spring 516 can make the scraping force more evenly distributed on the surface of the fan blade 4, avoiding local excessive stress that can cause deformation or damage to the fan blade 4. At the same time, uniform stress also helps to improve the dust removal effect and ensure that the fan blade 4 is thoroughly cleaned.

[0042] When the convex plate 54 moves away from below the first auxiliary block 56 with the first cylinder 58, the irregular rotating block 59 and the first spring 510, the first spring 510 resets and moves the irregular rotating block 59 upward, the irregular rotating block 59 drives the first cylinder 58 to move into the circular hole in the slide column 55, and the first cylinder 58 clamps the slide column 55 to prevent it from moving. When the convex plate 54 moves to below the second auxiliary block 57 with the first cylinder 58, the irregular rotating block 59 and the first spring 510, the first cylinder 58 moves away from the inside of the circular hole of the slide column 55 and does not clamp it. At this time, the moving block 511 will touch and block the end of the second auxiliary block 57 which has the same width as the first auxiliary block 56. When the convex plate 54 moves away from the rotating shaft 3, the moving block 511 drives the slide column 55 to move towards the rotating shaft 3. The movement of the slide column 55 drives the second cylinder 513 to slide from the top end to the bottom end of the inclined groove of the auxiliary plate 512. In this process, the auxiliary plate 512 moves upward, driving the scraper 515 to move upward. Through the cooperation of the auxiliary assembly 5, when the convex plate 54 moves and touches the first auxiliary block 56, the irregular rotating block 59 is pressed against the first spring 510 and drives the first cylinder 58 to move upward, positioning it inside the slide column 55. The first auxiliary block 56 drives the moving block 511 to move the slide column 55, which moves the scraper 515 to tightly contact the fan blade 4. When the convex plate 54 moves back, the scraper 515 cleans the dust on the surface of the fan blade 4. After cleaning, the slide column 55 moves to retract the scraper 515 when the irregular rotating block 59 is pressed by the second auxiliary block 57. This realizes the automatic ejection and retraction of the scraper 515, which can simultaneously scrape the dust on both sides of the fan blade 4, saving cleaning time and effort, simplifying the cleaning steps and improving the cleaning efficiency. Cleaning both sides can maintain the balance of the fan and reduce the imbalance caused by single-sided cleaning. By using single-direction cleaning for the fan blade 4, it can avoid the possibility of secondary pollution caused by the cleaned area being contaminated by the uncleaned area.

[0043] When the fan blade 4 is damaged and needs to be replaced, the operator presses the clamping block 62 with force, the clamping block 62 drives one end of the spring sheet 61 to move away from below the blocking plate 65, so that the spring sheet 61 is not blocked by the blocking plate 65, at this time, by moving the fan blade 4, the fan blade 4 drives the spring sheet 61 to move away from the inside of the rubber pad 64, the damaged fan blade 4 is replaced, when installing the fan blade 4, only need to insert the spring sheet 61 into the inside of the rubber pad 64, when the spring sheet 61 is inserted, it will be extruded by the blocking plate 65, when the spring sheet 61 completely enters the inside of the rubber pad 64, the spring sheet 61 is clamped below the blocking plate 65 after resetting, and the clamping block 62 is located in the clamping groove 66, through the cooperation of the easy-to-disassemble assembly 6, the damaged fan blade 4 can be easily disassembled and replaced by simple movement, this design makes the replacement of the fan blade 4 very simple and fast, and the damaged fan blade 4 can be easily replaced without complex tools, the quick replacement of the fan blade 4 can reduce the downtime caused by the damage of the fan blade 4 and improve the work efficiency, since the spring sheet 61 is V-shaped, the V-shaped structure can provide a large and uniform elastic restoring force, so that the spring sheet 61 can stably play the role of clamping or releasing in the working process, the unique shape design not only provides the elastic function, but also occupies a relatively small space, which is suitable for devices with limited space, through the setting of the rubber pad 64, the friction force on the surface of the spring sheet 61 can be increased, so that the gripping force of the easy-to-disassemble assembly 6 is improved, the fan blade 4 is prevented from falling off in movement or vibration, and has good elasticity and buffering performance, so that a part of impact force can be absorbed when the spring sheet 61 is used, and damage caused by impact or vibration is reduced.
