Description

Technical Field

[0001] This utility model relates to the technical field of frequency converter cabinet maintenance, and in particular to a self-cleaning, dustproof, and heat-dissipating frequency converter cabinet. Background Technology

[0002] In industrial automation, frequency converter cabinets play a crucial role. However, frequency converters generate a significant amount of heat during operation. If this heat cannot be dissipated in time, excessively high internal temperatures will affect performance and lifespan. Meanwhile, industrial environments are often dusty. Dust entering the frequency converter cabinet not only hinders heat dissipation but can also cause short-circuit faults.

[0003] Currently, inverter cabinets utilize natural cooling, forced fan cooling, and air conditioning for heat dissipation. Natural cooling is inefficient and insufficient for high-power applications; forced fan cooling allows dust to enter, increasing the difficulty of dust control; air conditioning is costly, requiring additional equipment and space, and incurring high maintenance costs. Regarding dust control, sealing strips are prone to aging and deformation, and dust filters impede ventilation and require regular cleaning. Utility Model Content

After secondary filtration and guidance by the dustproof guide plate, it is gradually dispersed to various parts of the cabinet, thereby cooling the components inside. The heat dissipation and dust removal components can move up and down outside the cabinet, and can flexibly change the ventilation position of the cabinet according to the movement position, so as to better realize the heat dissipation function.

[0017] Furthermore, the fan inside the heat dissipation and dust removal component can flexibly change the airflow direction to deliver air into the cabinet and blow dust outwards, thus cleaning the dust covering the outside of the heat dissipation and dust removal component while performing heat dissipation, thereby avoiding affecting the heat dissipation efficiency.

[0026] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0028] Reference Figures 1 to 7 This embodiment provides a self-cleaning, dustproof, and heat-dissipating inverter cabinet, which includes a cabinet body 100 and a ventilation window 101 on the side wall of the cabinet body 100.

[0029] The cabinet 100 is preferably made of 304 stainless steel. The cabinet door is installed on the front of the cabinet 100 and is equipped with indicator lights and transparent glass windows to facilitate observation of the usage of the components inside the cabinet 100.

[0030] Ventilation windows 101 are symmetrically opened on both sides of the cabinet 100. The ventilation windows 101 are rectangular windows that are opened vertically and can cover the installation range of the internal components.

[0031] The dustproof component 200 includes a dustproof guide plate 201 and a fixing frame 202 fixed to its side wall. The dustproof guide plate 201 is fixed to the inner wall of the cabinet 100 corresponding to the ventilation window 101, and the fixing frame 202 is set in the ventilation window 101.

[0032] Reference Figure 7 The dustproof guide plate 201 consists of a dust baffle plate 201a and a dust baffle net 201b. The dust baffle plate 201a is a whole rectangular stainless steel plate located inside the cabinet 100. It can block the ventilation window 101 in the horizontal direction. The fixed frame 202 has the same size as the ventilation window 101 and can be placed inside the ventilation window 101.

[0033] The heat dissipation and dust removal component 300 is movably mounted on the fixed frame 202 and covers part of the ventilation window 101.

[0034] The heat dissipation and dust removal component 300 can move up and down along the fixed frame 202. When it is located below the cabinet 100, the fan installed inside the heat dissipation and dust removal component 300 can introduce external natural air into the cabinet 100 from below and exhaust it from the cabinet 100 through the ventilation window 101 above, forming a counterclockwise heat exchange route.

[0035] If the heat dissipation and dust removal component 300 is located above the cabinet 100, the fan installed inside the heat dissipation and dust removal component 300 can introduce external natural air into the cabinet 100 from above and exhaust it from the cabinet 100 through the ventilation window 101 below, forming a clockwise heat exchange route.

[0036] As an optional embodiment, the heat dissipation and dust removal assembly 300 includes a mounting frame 301, an inner mesh 302, an outer mesh 303, and a fan assembly 304.

[0037] Reference Figure 2 The two openings on the sides of the mounting frame 301 are the positive air intake A1 and the negative air intake A2, respectively. The positive air intake A1 is the air inlet for heat dissipation of the cabinet 100, and the natural air flows from left to right. The negative air intake A2 is the air inlet for dust removal of the cabinet 100, and the hot air inside the cabinet 100 flows from right to left.

[0038] The outer net 303 is hinged at both ends to the inner wall of the front wind end A1 of the mounting frame 301, and several sets of the outer net 303 are arranged. The outer net 303 can rotate along the hinge point.

[0039] In its natural state, the outer net 303 is set vertically. At this time, the outer net 303 can only rotate counterclockwise by a certain angle. At this time, an inclined air duct A3 is formed between adjacent outer nets 303, and the inclined air duct A3 is inclined towards the ground.

[0040] The two ends of the inner net 302 are slidably inserted into the inner wall of the reverse wind end A2 of the mounting frame 301. The two ends of the inner net 302 near the inner wall of the mounting frame 301 are also fixedly connected to the front push plate 302a, which faces the reverse wind end A2.

[0041] The inner network 302 and the outer network 303 are also hinged to the inner ends of the mounting frame 301 with connecting push rods 303a, as shown in the reference. Figure 2 When the inner net 302 moves horizontally to the left, it can push the outer net 303 to rotate counterclockwise through the connecting push rod 303a.

[0042] A protective frame 301a is fixedly connected to the inner walls on both sides of the reverse end A2 and the inner network 302. A lead screw 301b is rotatably inserted into the protective frame 301a. The top of the lead screw 301b extends to the outside of the top protective frame 301a and is fixedly connected to the output shaft of the drive motor 301c at the top of the protective frame 301a. When the drive motor 301c is started, it can drive the lead screw 301b to rotate forward and backward.

[0043] The fan assembly 304 includes a mounting plate 304a and fans 304b arranged and fixedly connected inside it. The two ends of the mounting plate 304a are slidably inserted into the protective frame 301a, and the lead screw 301b is threaded into the two ends of the mounting plate 304a.

[0044] The top of both ends of the mounting plate 304a is connected to an auxiliary push plate 304a-1 facing the inner net 302. The top and bottom of the auxiliary push plate 304a-1 near the inner net 302 are provided with a forward push slope X1. The forward push slope X1 slides in contact with the auxiliary push slope X2 at the end of the forward push plate 302a.

[0045] During use, in the initial working state, the outer mesh 303 hangs vertically and is mutually sealed and cooperated, and the inclined air duct A3 disappears; the fan assembly 304 is located above the mounting frame 301. At this time, several sets of fans 304b in the fan assembly 304 start and send air into the cabinet 100. The outside natural wind first passes through the preliminary filtration of the outer mesh 303, and then passes through the inner mesh 302 for filtration again before entering the dustproof assembly 200 for final filtration.

[0046] Due to long-term use, the outer wall of the outer mesh 303, which is the first filtration stage, will be covered with a lot of dust, and there will also be some dust on the left side of the inner mesh 302. At this time, the dust needs to be removed.

[0047] In the initial working state, the forward push slope X1 below the auxiliary push plate 304a-1 abuts against the auxiliary push slope X2 above the front push plate 302a. When dust removal starts, the drive motor 301c starts, driving the fan assembly 304 to move downward. The forward push slope X1 pushes the auxiliary push slope X2, further pushing the inner mesh 302 to the left. At the same time, the fan 304b reverses and blows air towards the positive wind end A1.

[0048] Furthermore, the leftward movement of the inner mesh 302 causes the outer mesh 303 to tilt outward, opening the inclined air duct A3. The fan 304b, blowing air to the left, draws the hot air inside the cabinet 100 from right to left. At this time, the drawn-out hot air blows the dust off the left side of the inner mesh 302 and the outer mesh 303 from right to left. The dust on the outer mesh 303 will be blown directly to the ground, while the dust on the inner mesh 302 will be blown to the ground from the inclined air duct A3.

[0049] Furthermore, as the fan assembly 304 moves downward, the inner mesh 302 and outer mesh 303 combination at the top opens first. When the fan assembly 304 moves to the second set of inner mesh 302 and outer mesh 303 combinations, the first set of inner mesh 302 and outer mesh 303 combinations will naturally close under the weight of the outer mesh 303. As the fan assembly 304 moves, each set of inner mesh 302 and outer mesh 303 combinations will open first and then close. Similarly, when the fan assembly 304 moves to the lower left, the drive motor 301c flips, causing the fan assembly 304 to move upward. From bottom to top, each set of inner mesh 302 and outer mesh 303 combinations will open first and then close, achieving a cycle of dust removal.

[0050] The dustproof guide plate 201 includes a dust baffle plate 201a and a dust baffle net 201b, and the fixing frame 202 is fixedly connected to the edge of the dust baffle net 201b.

[0051] The dust net 201b is fixed to one side of the dust baffle 201a by the top column 201a-1.

[0052] A ventilation gap Q is formed between the dust baffle 201b and the dust baffle plate 201a, allowing both heat dissipation airflow and dust removal airflow to flow within the ventilation gap Q. A guide baffle 201a-2 is also fixedly connected to the edge of the dust baffle plate 201a near the dust baffle 201b, outside the coverage area of ​​the dust baffle 201b.

[0053] The baffle 201a-2 is set from the top of the cabinet 100 to the bottom of the cabinet 100, and the baffle 201a-2 forms a diffuser 201a-2a between the baffles 201a-2.

[0054] During use, the airflow is guided by the baffle 201a-2 and flows neatly to the top and bottom of the cabinet 100 before finally entering the cabinet 100.

[0055] The top and bottom of the protective frames 301a on both sides facing the reverse wind end A2 are symmetrically fixed with plug rods 301a-1.

[0056] A slot 301a-1a is provided on one side of the two insert rods 301a-1 opposite to each other. A block 301a-1b is also fixedly connected to the end of the insert rod 301a-1 on this side. A connecting plate 301a-1c is connected between the blocks 301a-1b on the same side.

[0057] A push plate 202a is symmetrically slidably arranged inside the fixed frame 202. A slide rod 202a-1 is fixedly connected to both ends of the push plate 202a. A docking plate 202a-2 is detachably fixedly connected to the slide rod 202a-1.

[0058] A spring T is fixedly connected to the side wall of the mating plate 202a-2. The other end of the spring T is fixed to the boss 202c that is symmetrically connected to the top and bottom outer walls of the fixed frame 202. The boss 202c is located between the two mating plates 202a-2.

[0059] Several sets of locking teeth 202a-3 are arranged and fixed on the opposite side of the two locking plates 202a. The insertion rod 301a-1 is slidably inserted between the locking plate 202a and the fixed frame 202, and the locking teeth 202a-3 are slidably inserted into the slot 301a-1a.

[0060] During use, when installing the heat dissipation and dust removal component 300, the push plate 202a needs to be pushed towards the center. The spring T retracts, and the gap between the push plate 202a and the fixed frame 202 increases. The card block 301a-1b can be inserted into the gap until the card slot 301a-1a moves to the corresponding position of the push plate 202a. The push plate 202a springs back, and the card tooth 202a-3 is inserted into the card slot 301a-1a.

[0061] Furthermore, the engagement of the card teeth 202a-3 with the card slot 301a-1a, the engagement of the card block 301a-1b with the side wall of the card push plate 202a, and the abutment of the connecting plate 301a-1c with the side wall of the card push plate 202a ensure that the heat dissipation and dust removal assembly 300 is stably fixed on the fixed frame 202.

[0062] Furthermore, when it is necessary to adjust the overall height of the heat dissipation and dust removal component 300, it is necessary to slightly push the two side push plates 202a to make the tooth 202a-3 contact and engage with the slot 301a-1a, and then the heat dissipation and dust removal component 300 can be lifted and adjusted.

[0063] The self-cleaning, dustproof, and heat-dissipating inverter cabinet also includes a temperature sensor 400, which is evenly distributed on the inner wall of the cabinet 100.

[0064] The control unit 500 includes a comparator 501 and a relay 502 electrically connected thereto, and a temperature sensor 400 is electrically connected to the comparator 501.

[0065] Among them, relay 502 is provided in several groups and is electrically connected to drive motor 301c and fan 304b.

[0066] During use, the temperature sensor 400 monitors the ambient temperature inside the cabinet 100 in real time and converts the temperature signal into a voltage signal.

[0067] Furthermore, comparator 501 compares the electrical signal from temperature sensor 400 with the electrical signal corresponding to its preset temperature threshold. When the actual temperature is higher than the high temperature threshold, comparator 501 outputs a high-level signal; when the actual temperature is lower than the low temperature threshold, comparator 501 outputs a low-level signal.

[0068] Relay 502 operates according to the signal output by comparator 501. When a high-level signal is received, the normally open contact of relay 502 closes and the normally closed contact opens, causing the drive motor 301c to run in one direction. When a low-level signal is received, the contact state of relay 502 reverses, thereby changing the current direction of drive motor 301c and realizing the forward and reverse rotation of drive motor 301c.

[0069] Similarly, when comparator 501 outputs a high level, it closes one set of normally open contacts of relay 502 and opens the normally closed contacts, allowing current to flow through the fan motor in one direction, causing fan 304b to rotate forward; when comparator 501 outputs a low level, the contact state of relay 502 changes, the current direction is reversed, and fan 304b rotates in reverse.

[0070] The forward and reverse rotation of the drive motor 301c can control the fan assembly 304 to perform dust removal operations, and the forward and reverse rotation of the fan 304b can achieve cooling and auxiliary dust removal of the cabinet 100.

[0071] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
