Description

Technical Field

[0001] This utility model belongs to the technical field of electromechanical equipment, and particularly relates to a heat dissipation power distribution cabinet for electromechanical equipment. Background Art

[0002] In modern industrial production and daily life, electromechanical equipment is widely used. As a key component of electromechanical equipment, the power distribution cabinet undertakes important functions such as power distribution, control, and protection. With the continuous progress of technology and the increasing complexity of electromechanical equipment, the heat generated during its operation is also increasing. Efficient and reliable heat dissipation is crucial for ensuring the normal operation of electrical components in the power distribution cabinet, extending its service life, and guaranteeing the stability of the entire system.

[0003] Traditional heat dissipation solutions for power distribution cabinets usually simply open ventilation holes on the cabinet body to allow natural convection of air to carry away heat. However, this method has significant drawbacks. During the non-heat dissipation stage, external dust, moisture, and various tiny particles can easily enter the power distribution cabinet through the ventilation holes. These impurities gradually accumulate inside the power distribution cabinet, may cover the surface of electrical components, resulting in a decrease in insulation performance, short circuits, and other faults, seriously affecting the working efficiency and reliability of electrical components.

[0004] In addition, the fixed-size ventilation holes cannot adapt to the changing heat dissipation requirements in different working scenarios. In a high-temperature environment or when the equipment is operating at high load, the heat dissipation requirement increases. If the ventilation holes are too small, insufficient heat cannot be discharged in time, which will cause the temperature inside the power distribution cabinet to rise rapidly, thereby affecting the equipment performance and even leading to serious problems such as overheating shutdown. On the contrary, in a low-temperature environment or when the equipment is operating at low load, the too-large ventilation holes will allow too much dust and impurities to enter, increasing the cost and frequency of equipment maintenance.

[0005] To improve this situation, the industry has made a series of attempts and improvements. Some use complex multi-layer filter structures to filter dust, but this method not only increases the cost but also easily leads to an increase in ventilation resistance, affecting the heat dissipation effect, and the replacement and maintenance of the filter are also relatively cumbersome. Some install electric valves to control the opening and closing of the ventilation holes, but the response speed of the electric valves is slow, it is difficult to achieve fast and flexible adjustment, and there are also certain problems with their reliability and durability.

[0006] Therefore, we propose a heat dissipation power distribution cabinet for electromechanical equipment. This device can not only prevent dust from entering when dissipating heat and not dissipating heat, but also flexibly adjust the size of the air inlet through holes to improve the heat dissipation effect. Summary of the Utility Model

[0007] The purpose of this utility model is to provide a heat dissipation power distribution cabinet for electromechanical equipment. This device can not only prevent dust from entering when dissipating heat and when not dissipating heat, but also flexibly adjust the size of the air inlet through holes to improve the heat dissipation effect.

[0008] The technical solution adopted by this utility model is as follows:

[0009] A heat dissipation power distribution cabinet for electromechanical equipment, including a base and a cabinet body arranged on the top of the base. The base is provided with a first chute and a driving component. The driving component is provided with a winding roller located inside the first chute, and a filter mesh cloth is wound around the winding roller;

[0010] Both sides of the cabinet body are provided with a first through groove and a second through groove. The first through groove and the second through groove are communicated. Second chutes are opened on the inner walls of the first through groove and the second through groove. An elastic compression component is arranged inside the second chute. A sealing plate that slides in the first through groove and the second through groove is arranged on the elastic compression component, and the bottom of the sealing plate is connected to the filter mesh cloth.

[0011] Furthermore, a sealing door is hinged on the cabinet body.

[0012] Furthermore, the driving component includes a rotating rod arranged on the two winding rollers. One end of the rotating rod far away from the winding roller penetrates through the base and is installed with a rotating disk. A first motor is installed on the rotating disk, and a transmission belt is arranged on the two rotating disks.

[0013] Furthermore, the width of the first through groove is greater than the width of the second through groove.

[0014] Furthermore, the elastic compression component includes a fixed shaft arranged inside the second chute. A slider and a spring are sleeved on the fixed shaft. The bottom of the slider is connected to the spring, and one side of the slider is connected to the sealing plate.

[0015] Furthermore, a dust removal brush is arranged inside the first chute.

[0016] Furthermore, a through hole is opened on the top of the cabinet body. A bracket is arranged inside the through hole. A second motor is arranged on the bracket, and a fan blade is installed at the output end of the second motor.

[0017] The technical effects obtained by this utility model are:

[0018] First, when the power distribution cabinet does not need to dissipate heat, such as Figure 1As shown, when the driving component works, the driving component drives the winding roller to rotate inside the first chute. When the winding roller rotates, it winds the filter mesh cloth. When winding, a pulling force is generated, and this pulling force drives the sealing plate to move downward inside the first through groove and the second through groove, and at the same time compresses the elastic compression component, thereby achieving sealing to prevent dust from entering. When the power distribution cabinet needs to dissipate heat urgently, such as Figure 2 As shown, when the driving component rotates in the reverse direction, the driving component drives the winding to rotate inside the first chute. When the winding roller rotates in the reverse direction, the filter mesh cloth is in the unwinding state. When unwinding, the elastic potential energy stored in the elastic compression component is restored, thereby driving the sealing plate to move upward inside the first through groove and the second through groove. Through the filter mesh cloth, dust can be prevented from entering during heat dissipation. If you want to open the air inlet through hole a little larger, you can make the winding roller rotate more, thereby adjusting the size of the air inlet through hole and improving the heat dissipation effect. This device can not only prevent dust from entering when dissipating heat and not dissipating heat, but also adjust the size of the air inlet through hole and improve the heat dissipation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the purpose and advantages of this utility model clearer, the following will specifically describe this utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model, and does not strictly limit the scope of protection of the specific claims of this utility model.

[0028] As Figures 1-6 shown, the technical solution adopted by this utility model is specifically as follows: A heat dissipation power distribution cabinet for electromechanical equipment, including a base 1 and a cabinet body 2 arranged on the top of the base 1. A first chute 3 and a driving component are arranged on the base 1. A winding roller 4 located inside the first chute 3 is arranged on the driving component. A filter mesh cloth 5 is wound around the winding roller 4;

[0029] First through grooves 6 and second through grooves 7 are opened on both sides of the cabinet body 2. The first through groove 6 and the second through groove 7 are communicated. Second chutes 8 are opened on the inner walls of the first through groove 6 and the second through groove 7. An elastic compression component is arranged inside the second chute 8. A sealing plate 9 that can slide in the first through groove 6 and the second through groove 7 is arranged on the elastic compression component. The bottom of the sealing plate 9 is connected to the filter mesh cloth 5.

[0030] Its working principle is as follows: First, when the power distribution cabinet does not need to dissipate heat, as Figure 1 shown, the driving component works. The driving component drives the winding roller 4 to rotate inside the first chute 3. When the winding roller 4 rotates, it winds up the filter mesh cloth 5. When winding up, a pulling force is generated. This pulling force drives the sealing plate 9 to move downward inside the first through groove 6 and the second through groove 7, and at the same time compresses the elastic compression component, thereby achieving sealing and preventing dust from entering. When the power distribution cabinet needs to dissipate heat, as Figure 2 shown, the driving component rotates in the reverse direction. The driving component drives the winding to rotate inside the first chute 3. When the winding roller 4 rotates in the reverse direction, the filter mesh cloth 5 is in a state of unwinding. When unwinding, the elastic potential energy stored in the elastic compression component is restored, thereby driving the sealing plate 9 to move upward inside the first through groove 6 and the second through groove 7. The filter mesh cloth 5 can prevent dust from entering during heat dissipation. If you want to open the air inlet through hole 18 larger, you can make the winding roller 4 rotate more, thereby adjusting the size of the air inlet through hole 18 and improving the heat dissipation effect. This device can not only prevent dust from entering when dissipating heat and not dissipating heat, but also adjust the size of the air inlet through hole 18 to improve the heat dissipation effect.

[0031] Among them, a sealing door 10 is hinged on the cabinet body 2, and the cabinet body 2 can be sealed through the sealing door 10.

[0032] Meanwhile, the driving component includes rotating rods arranged on two winding rollers 4. One end of the rotating rod away from the winding roller 4 penetrates through the base 1 and is equipped with a rotating disk 11. A first motor 12 is installed on the rotating disk 11, and a conveyor belt 13 is arranged on the two rotating disks 11.

[0033] The first motor 12 drives one of the rotating disks 11 to rotate, and then drives the other rotating disk 11 to rotate through the conveyor belt 13. When the rotating disk 11 rotates, it drives the winding roller 4 to rotate.

[0034] The filter screen cloth 5 is made of nylon. Nylon filter screens are widely used due to their good wear resistance, corrosion resistance, and relatively high strength. Nylon materials have a long service life and are easy to clean and maintain.

[0035] The width of the first through groove 6 is greater than that of the second through groove 7. Such a setting can hide the sealing plate 9 inside the second through groove 7 without causing interference during sealing.

[0036] The elastic compression component includes a fixed shaft 14 arranged inside the second chute 8. A slider 15 and a spring 16 are sleeved on the fixed shaft 14. The bottom of the slider 15 is connected to the spring 16, and one side of the slider 15 is connected to the sealing plate 9.

[0037] When the filter screen cloth 5 drives the sealing plate 9 to move downward, the sealing plate 9 drives the slider 15 to compress the spring 16 on the fixed shaft 14, thus compressing it. When the elastic potential energy is restored, the elastic force of the spring 16 drives the slider 15 to make the sealing plate 9 drive the filter screen cloth 5 to move, so as to open the air inlet through hole 18 for heat dissipation.

[0038] It should be noted that: the elastic force of the spring 16 is carefully designed and calculated to ensure that it can provide sufficient force to push the sealing plate 9 to move when needed, so as to open or close the air inlet through hole 18.

[0039] The elastic force of the spring 16 can be calculated by Hooke's law, that is, the elastic force F of the spring 16 is proportional to its deformation amount x and inversely proportional to the spring constant k of the spring 16. The formula is expressed as: F = kx.

[0040] In practical applications, it is necessary to determine the spring constant k and the initial pre-tightening force of the spring 16 according to factors such as the mass of the sealing plate 9, friction force, resistance of the filter screen cloth 5, and the required opening and closing speeds. (This belongs to the prior art and will not be elaborated here).

[0041] A cleaning brush 17 is arranged inside the first chute 3, which can clean the impurities on the filter screen cloth 5 during winding and unwinding, thereby improving the heat dissipation effect.

[0042] A through hole 18 is provided at the top of the cabinet body 2. A bracket is arranged inside the through hole 18, and a second motor 19 is arranged on the bracket. A fan blade 20 is installed at the output end of the second motor 19. The second motor 19 drives the fan blade 20 to rotate, so as to make the air circulate for heat dissipation.

[0043] The working principle of this utility model is as follows: First, when the power distribution cabinet does not need to dissipate heat, as Figure 1 shown, the driving component works. The driving component drives the winding roller 4 to rotate inside the first chute 3. When the winding roller 4 rotates, it winds up the filter net cloth 5. When winding up, a pulling force is generated. This pulling force drives the sealing plate 9 to move downward inside the first through groove 6 and the second through groove 7, and at the same time compresses the elastic compression component, so as to conduct sealing and prevent dust from entering. When the power distribution cabinet needs to dissipate heat, as Figure 2 shown, the driving component rotates in the reverse direction. The driving component drives the winding to rotate inside the first chute 3. When the winding roller 4 rotates in the reverse direction, the filter net cloth 5 is in the unwinding state. When unwinding, the elastic potential energy stored in the elastic compression component is restored, so as to drive the sealing plate 9 to move upward inside the first through groove 6 and the second through groove 7. The filter net cloth 5 can prevent dust from entering during heat dissipation. If you want to open the air inlet through hole 18 a little larger, you can make the winding roller 4 rotate more, so as to adjust the size of the air inlet through hole 18 and improve the heat dissipation effect. This device can not only prevent dust from entering when dissipating heat and not dissipating heat, but also adjust the size of the air inlet through hole 18 to improve the heat dissipation effect.

[0044] The above is only the preferred embodiment of this utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of this utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
