Description

Technical Field

[0001] The present invention relates to the field of electrical equipment protection, and particularly to a shock-proof device for an electrical control cabinet. Background Art

[0002] The electrical control cabinet is the core equipment of the industrial automation system. By integrating components such as programmable logic controllers (PLCs), circuit breakers, and relays, it realizes the intelligent control and monitoring of equipment. The electrical control cabinet is widely used in fields such as factory production lines, intelligent transportation, and new energy. It has the capabilities of remote monitoring, fault alarm, and modular expansion, and is the key terminal node for the industrial Internet of Things to achieve equipment interconnection and efficient management.

[0003] The existing patent with the publication number CN213753679U discloses a shock-proof and dehumidifying electrical control cabinet for wind power generation, including a base. The inner wall of the base is connected with a second magnet, and a water storage cylinder is connected between the base and the second magnet; a first drain pipe matching the water storage cylinder is inserted into the outer wall of the base; a box body is arranged on the inner wall of the base. The inner wall of the box body is connected with a first moisture absorption cotton, the bottom wall of the first moisture absorption cotton is connected with a drain nozzle, the bottom wall of the drain nozzle is connected with a drain pipe, and the drain pipe is inserted into the box body; the bottom wall of the inner wall of the box body is connected with a rubber shock pad, and a placement rack is connected to the top wall of the rubber shock pad; the bottom of the outer wall of the box body is connected with a first magnet matching the second magnet.

[0004] However, in the prior art, the electrical control cabinet generally uses fixed heat dissipation holes for heat dissipation. When the electrical control cabinet is operating, the fixed heat dissipation holes can only rely on natural convection or limited mechanical ventilation for heat exchange. Especially when the electrical control cabinet is operating at high load or when local components generate heat abnormally, the fixed heat dissipation holes cannot effectively cover all the heat generation areas, easily form heat accumulation inside the cabinet, resulting in too high local temperature and the problem of incomplete heat dissipation, seriously affecting the operating stability of the electrical control cabinet and the service life of components.

[0005] The information disclosed in the background art part of the present invention is only intended to deepen the understanding of the general background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0006] Based on this, it is necessary to provide a shock-proof device for an electrical control cabinet in view of the problem that the existing shock-proof device for the electrical control cabinet has incomplete heat dissipation, resulting in accelerated aging of internal components.

[0007] The above object is achieved by the following technical solutions:

[0008] A shock-proof device for an electrical control cabinet includes:

[0009] Main housing, which is fixedly connected to the electrical control cabinet. The main housing is provided with an elastic surface and a plurality of heat dissipation channels. The elastic surface and the main housing enclose a sealed first chamber. The elastic surface is located on the side of the main housing away from the electrical control cabinet, and the elastic surface is used to offset external loads through its own deformation. The plurality of heat dissipation channels are located on the side wall surface of the elastic surface close to the electrical control cabinet, and the heat dissipation channels are used to connect the inside of the electrical control cabinet and the first chamber.

[0010] Wherein, the elastic surface has a natural state, an initial tension state and a stressed stretching state. When the elastic surface is not subject to any external force, the elastic surface is in the natural state; when the elastic surface is in a taut state under the action of an initial stress, the elastic surface is in the initial tension state; when the elastic surface is stretched under the action of an external load, the elastic surface is in the stressed stretching state.

[0011] Reset assembly, the reset assembly is used to make the elastic surface return to the initial tension state. The reset assembly includes a plurality of first one-way valves, and the first one-way valves connect the external environment and the first chamber.

[0012] Rotating assembly, the rotating assembly is used to drive the elastic surface to move forward.

[0013] In one embodiment, it includes a tensioning device. The tensioning device is fixedly connected to the main housing, and the tensioning device makes the elastic surface in the initial tension state.

[0014] In one embodiment, the tensioning device is provided with a first elastic member, and the elastic force of the first elastic member always makes the elastic surface in the initial tension state or has a tendency to return to the initial tension state.

[0015] In one embodiment, a plurality of one-way plates are arranged on the elastic surface. When the elastic surface is in the initial tension state, the one-way plates restrict the gas exchange between the first chamber and the electrical control cabinet; when the elastic surface is in the stressed stretching state, the one-way plates connect the first chamber and the electrical control cabinet.

[0016] In one embodiment, the reset assembly includes a plurality of first one-way valves, and the first one-way valves are used to connect the external environment and the first chamber.

[0017] In one embodiment, the elastic surface can rotate around the tensioning device. The elastic surface drives the one-way plate to move, and makes the one-way plate have a corresponding first stroke and second stroke. When in the first stroke, it restricts the gas exchange between the external environment and the first chamber; when in the second stroke, the gas in the first chamber can flow to the inside of the electrical control cabinet through the one-way plate.

[0018] In one embodiment, it includes a rotating assembly, and the rotating assembly is used to drive the elastic surface to move forward around the tensioning device.

[0019] In one embodiment, the rotating assembly includes a first rotating shaft and a second rotating shaft. The first rotating shaft is coaxially sleeved on the second rotating shaft. The first rotating shaft is provided with an anti-reverse groove, and the second rotating shaft is provided with a limiting block that cooperates with the anti-reverse groove.

[0020] In one embodiment, it includes a driving assembly, and the driving assembly is used to drive the rotating assembly to rotate periodically.

[0021] In one embodiment, it includes a plurality of pressure sensors, and the pressure sensors are used to cause the driving assembly to drive the rotating assembly to rotate after the elastic surface is deformed and restored under an external load.

[0022] The beneficial effects of the present invention are:

[0023] The present invention provides a shock-proof device for an electric control cabinet, including: a main housing, a reset assembly, and a rotating assembly. The main housing is provided with an elastic surface and a plurality of heat dissipation channels. The elastic surface and the main housing enclose a sealed first chamber. The elastic surface is located on the side of the main housing away from the electric control cabinet, and the elastic surface is used to offset external loads through its own deformation. The plurality of heat dissipation channels are located on the side wall surface of the elastic surface close to the electric control cabinet, and the heat dissipation channels are used to connect the inside of the electric control cabinet and the first chamber. The reset assembly is used to make the elastic surface return to the initial tension state. The rotating assembly is used to drive the elastic surface to move forward. When an external load acts on the elastic surface, the elastic surface effectively offsets the external impact through its own deformation, reducing the vibration of the electric control cabinet. The deformation of the elastic surface causes the gas in the first chamber to enter the electric control cabinet through the heat dissipation channels, which can dissipate heat from the electric control cabinet. The rotating assembly rotates the elastic surface and moves the position of the heat dissipation channels, which can dissipate heat from the electric control cabinet comprehensively. Thus, it can make the shock-proof device of the electric control cabinet improve the heat dissipation effect of the electric control cabinet while having a shock-absorbing effect.

[0039] The following refers to Figures 1 - 10 Describe the shock-proof device 200 of the electric control cabinet provided by the embodiment of this invention.

[0040] As Figures 1 - 6 shown, the shock-proof device 200 of the electric control cabinet provided by the embodiment of this invention includes:

[0041] The main housing 210, the main housing 210 can enclose to form a space relatively isolated from the external environment, and most of the other components are located in this space to protect the components inside the main housing 210.

[0042] For an electric control cabinet used outdoors at a high place, there will be a relatively large external load, and the external load will cause a relatively large impact on the cabinet body of the electric control cabinet, which will not only cause a relatively large vibration to the cabinet body of the electric control cabinet, but also affect the stability of the components inside the electric control cabinet.

[0043] Based on this, the main housing 210 is fixedly connected to the electric control cabinet, and an elastic surface 220 and a plurality of heat dissipation channels are provided on the main housing 210. The elastic surface 220 is located on the side of the main housing 210 away from the electric control cabinet, and the elastic surface 220 is used to offset the external load through its own deformation.

[0044] Among them, the elastic surface 220 has a natural state, an initial tension state, and a stressed and stretched state. When the elastic surface 220 is not subject to any external force, the elastic surface 220 is in the natural state; when the elastic surface 220 is in a taut state under the action of a preset loading stress, the elastic surface 220 is in the initial tension state; when the elastic surface 220 is stretched under the action of an external load, the elastic surface 220 is in the stressed and stretched state.

[0045] It can be understood that the stressed and stretched state of the elastic surface 220 is affected by the magnitude of the external load.

[0046] The main housing 210 has a rectangular parallelepiped frame structure. A rectangular opening area is provided on a side wall surface of the main housing 210 away from the electric control cabinet, and the elastic surface 220 is closely attached to the opening area from the inside of the main housing 210.

[0047] When an external load acts on the elastic surface 220, the elastic surface 220 can deform towards the inside of the main housing 210, thereby absorbing the influence of the external load on the cabinet body of the electric control cabinet and improving the stability of the electric control cabinet.

[0048] Furthermore, in order to dissipate heat from the electric control cabinet while absorbing the external load, the elastic surface 220 and the main housing 210 enclose a sealed first chamber. A plurality of heat dissipation channels are uniformly provided on a side wall surface of the main housing 210 close to the electric control cabinet, and a plurality of second one-way valves are provided in the plurality of heat dissipation channels. The heat dissipation channels communicate the inside of the electric control cabinet with the first chamber.

[0049] A sealing structure is provided between the elastic surface 220 and the main housing 210 to ensure the sealing performance of the first chamber. A plurality of sealing strips 260 are provided at the contact positions between the elastic surface 220 and the main housing 210 to ensure seamless fitting between the elastic surface 220 and the main housing 210.

[0050] When an external load acts on the elastic surface 220, the elastic surface 220 is in the stressed and stretched state. At this time, the elastic deformation of the elastic surface 220 causes the internal volume of the first chamber to contract, and the air in the first chamber generates a pressure gradient due to volume compression, causing the second one-way valve to open. The pressure drives the air flow to enter the electric control cabinet through the heat dissipation channels, and the air flow enters the electric control cabinet for heat exchange to achieve efficient heat dissipation of the electric control cabinet.

[0051] The restoration component is used to make the elastic surface 220 return to the initial tension state.

[0052] Specifically, the reset component includes a plurality of first one-way valves 240, and the first one-way valves 240 communicate the external environment and the first chamber.

[0053] When an external load acts on the elastic surface 220, the pressure in the first chamber increases, causing the gas in the first chamber to enter the electric control cabinet. As the gas in the first chamber gradually enters the electric control cabinet, the pressure in the first chamber becomes equal to the pressure in the electric control cabinet, that is, in the atmospheric pressure state. However, at this time, the elastic surface 220 is still in the state of being stretched by the external force. At this time, the elastic surface 220 returns to its initial tension state, and the first chamber may enter a negative pressure state. During the process of the elastic surface 220 returning to its initial tension state, the first one-way valve 240 opens, and the gas in the external environment enters the first chamber through the first one-way valve 240 under the drive of the pressure difference. The pressure in the first chamber gradually increases until it returns to the atmospheric pressure state same as the external environment. Thus, by setting the first one-way valve 240, the elastic surface 220 returns to its initial tension state, and the first chamber returns to the atmospheric pressure state.

[0054] It can be understood that when the external load decreases or is completely eliminated, the first one-way valve 240 opens. At this time, the impurity content in the external environment is relatively low, and the amount of impurities entering the first chamber can be maintained at a relatively low level.

[0055] Thus, by setting the elastic surface 220 and the heat dissipation channel on the main housing 210, the external impact can be effectively offset by the deformation of the elastic surface 220 itself, greatly reducing the vibration of the electric control cabinet. At the same time, through the heat dissipation channel, when the elastic surface 220 deforms, the heat dissipation effect on the electric control cabinet is achieved.

[0056] It can be understood that the structure of the heat dissipation channel can be diverse, such as a straight tube type channel, a spiral type channel and other structures. The position of the sealing structure can be set on the elastic surface 220 or on the main housing 210, but the position of the sealing structure needs to ensure that the elastic surface 220 and the main housing 210 are closely attached. Other common sealing structures can be used in the present invention.

[0057] In addition, the elastic surface 220 is closely attached to the main housing 210 and relatively hinders the material exchange between the main housing 210 and the external environment, so that the elastic surface 220 can prevent more external impurities from entering the electric control cabinet, thereby improving the service life of the electric control cabinet.

[0058] Specifically, since the elastic surface 220 and the main housing 210 enclose a relatively closed first chamber, when the gas in the external environment enters, it needs to first flow into the first chamber and then flow from the first chamber to the inside of the electric control cabinet through the heat dissipation channel. Since the elastic surface 220 itself has a certain elasticity, the gap between it and other rigid structures including the main housing 210 is relatively small. Therefore, the amount of impurities that can enter the first chamber through these gaps is relatively small.

[0059] Alternatively, an air intake passage is provided in the main housing 210, and a filtering structure such as a filter screen is provided on the air intake passage. Since the elastic surface 220 itself can be well sealed with the main housing 210, the first chamber has good airtightness. The gas in the external environment can only enter the first chamber from the air intake passage. During this process, impurities are filtered by the filtering structure on the air intake passage, so that the impurities cannot enter the first chamber or the electric control cabinet.

[0060] In one embodiment, as Figures 4 - 6 shown, the shockproof device 200 includes a tensioning device 230. The tensioning device 230 is fixedly connected to the main housing 210. The tensioning device 230 provides an initial stress for the elastic surface 220, so that the elastic surface 220 is in an initial tensioned state.

[0061] Specifically, the elastic surface 220 is a ring-shaped structure. The tensioning device 230 applies a pre-tightening force to make the elastic surface 220 in an initial tensioned state.

[0062] When the elastic surface 220 is in a stressed and stretched state, the elastic surface 220 deforms adaptively according to the direction and strength of the external load, so that the elastic surface 220 is stretched. At this time, the elastic surface 220 has a certain pressure on the tensioning device 230, so that part of the external load is applied to the tensioning device 230, further offsetting the external load and improving the stability of the electric control cabinet.

[0063] When the external load decreases or disappears, the elastic surface 220 gradually returns to a deformation degree close to the initial tensioned state under its own elastic restoring force and the reverse acting force of the tensioning device 230.

[0064] It can be understood that the positions and numbers of the plurality of tensioning devices 230 can be diverse. For example, three tensioning devices 230 are provided, so that two of the tensioning devices 230 are arranged close to the outer wall surface of the main housing 210, and the remaining one tensioning device 230 is arranged in the middle part of the main housing 210, so that the elastic surface 220 can fit smoothly on the opening area of the main housing 210.

[0065] However, the positions and numbers of the plurality of tensioning devices 230 should ensure that the elastic surface 220 can fit smoothly on the main housing 210 to prevent external impurities from entering the inside of the main housing 210 and affecting the service life of the electric control cabinet.

[0066] Thus, by providing the tensioning device 230, the overall stability and seismic performance of the shockproof device 200 can be effectively improved, ensuring that the elastic surface 220 can quickly return to the initial state under the external load and reducing the vibration transmission.

[0067] It can be understood that the pre-tightening force of the tensioning device 230 on the elastic surface 220 directly affects the deformation range of the elastic surface 220, and thus determines the damping effect of the shockproof device 200. In addition, the deformation range of the elastic surface 220 can also be changed by changing the material of the elastic surface 220.

[0068] In addition, for the embodiment without the tensioning device 230, when installing the elastic surface 220, a certain pre-tensioning force can be applied to the elastic surface 220 by means of stretching, etc., and after tensioning, the elastic surface 220 is installed on the rigid structure including the main housing 210, thereby realizing the tensioning of the elastic surface 220.

[0069] In one embodiment, as Figures 4 - 6 shown, the tensioning device 230 is provided with a first elastic member 231, and the elastic force of the first elastic member 231 always makes the elastic surface 220 in an initial tensioned state or have a tendency to return to the initial tensioned state.

[0070] Specifically, when the elastic surface 220 is deformed by an external load, the first elastic member 231 is compressed to store elastic potential energy. When the external load decreases or disappears, the elastic potential energy of the first elastic member 231 is released, pushing the elastic surface 220 to make the elastic surface 220 return to the initial tensioned state.

[0071] It can be understood that when the elastic surface 220 is subjected to a large external load, the elastic force of the first elastic member 231 can offset the external load, preventing the elastic surface 220 from being greatly stretched, thereby increasing the service life of the elastic surface 220.

[0072] In one embodiment, as Figures 4 - 9 shown, a plurality of one-way plates 250 are provided on the elastic surface 220. When the elastic surface 220 is in the initial tensioned state, the one-way plates 250 restrict the gas exchange between the first chamber and the electric control cabinet; when the elastic surface 220 is in the stressed and stretched state, the one-way plates 250 connect the first chamber and the electric control cabinet.

[0073] Specifically, the elastic surface 220 is formed into an outer elastic surface 220 and an inner elastic surface 220, and the external load mainly acts on the outer elastic surface 220.

[0074] A plurality of one-way plates 250 are evenly distributed on the elastic surface 220. One end of the one-way plate 250 is rotatably connected to the elastic surface 220 through a second elastic member, and the elastic force of the second elastic member always makes the one-way plate 250 close to the elastic surface 220 or have a tendency to close to the elastic surface 220.

[0075] When the elastic surface 220 is in a stressed and stretched state, the pressure in the first chamber increases, causing the one-way plate 250 on the inner elastic surface 220 to rotate forward away from the elastic surface 220, enabling the first chamber to communicate with the electric control cabinet; when the elastic surface 220 is in an initial tension state, the one-way plates 250 on the outer elastic surface 220 and the inner elastic surface 220 closely adhere to the elastic surface 220, keeping the first chamber in a closed state.

[0076] Under the action of the same external load, the volume of the first chamber is smaller than that of the main housing 210. Since the pressure is negatively correlated with the volume, the pressure in the first chamber is greater.

[0077] When an external load acts on the elastic surface 220, the one-way plate 250 on the elastic surface 220 moves forward under the action of the pressure, and one end of the one-way plate 250 gradually moves away from the elastic surface 220, enabling the first chamber to communicate with the electric control cabinet. The greater pressure drives the air in the first chamber to form a higher-speed air flow, and the air flow flows out of the first chamber through the gap between the one-way plate 250 and the elastic surface 220 and then enters the electric control cabinet. Thus, the heat dissipation effect of the electric control cabinet is further improved.

[0078] In one embodiment, as Figures 4 - 6 shown, in order to be able to dissipate heat from the electric control cabinet more comprehensively, the elastic surface 220 can rotate around the tensioning device 230. The elastic surface 220 drives the one-way plate 250 to move, and the one-way plate 250 has corresponding first and second strokes. When in the first stroke, the gas exchange between the external environment and the first chamber is restricted; when in the second stroke, the gas in the first chamber can flow through the one-way plate 250 into the interior of the electric control cabinet.

[0079] Specifically, when in the first stroke, the one-way plate 250 is located on the outer elastic surface 220, and when in the second stroke, the one-way plate 250 is located on the inner elastic surface 220.

[0080] When the elastic surface 220 rotates around the tensioning device 230, it drives the position of the one-way plate 250 on the inner elastic surface 220 to change, which can change the path and orientation of the gas in the first chamber entering the electric control cabinet, continuously ensuring that the gas enters the interior of the electric control cabinet evenly from multiple directions, constantly refreshing and enhancing the air fluidity and heat exchange efficiency in the electric control cabinet, and greatly improving the heat dissipation efficiency.

[0081] In one embodiment, as Figures 4 - 10 shown, the shockproof device 200 includes a rotating assembly, and the rotating assembly is used to drive the elastic surface 220 to rotate around the tensioning device 230.

[0082] Specifically, the rotating assembly includes a first rotating shaft 270 and a second rotating shaft 280, and the first rotating shaft 270 is coaxially sleeved on the second rotating shaft 280.

[0083] To prevent the elastic surface 220 from moving in the reverse direction, an anti-reversal groove 271 is provided on the first rotating shaft 270, and the second rotating shaft 280 is provided with a limiting block 281 that cooperates with the anti-reversal groove 271. The limiting block 281 is embedded in the anti-reversal groove 271 to prevent the elastic surface 220 from moving in the reverse direction.

[0084] When the rotating assembly works, the limiting block 281 is embedded in the anti-reversal groove 271 to form a mechanical constraint, fundamentally preventing the first rotating shaft 270 from rotating in the reverse direction relative to the second rotating shaft 280, thereby ensuring that the elastic surface 220 only moves in the forward direction during the working process.

[0085] Since a plurality of one-way plates 250 are distributed on the elastic surface 220, as the elastic surface 220 continuously rotates, the plurality of one-way plates 250 do not move in the reverse direction, and can quickly change the air flow path, enabling the gas to have an all-round coverage range.

[0086] In one of the embodiments, as Figures 4 - 6 shown, the shockproof device 200 of the electric control cabinet includes a driving assembly, and the driving assembly is used to drive the rotating assembly to perform periodic rotation.

[0087] Specifically, the driving assembly provides a continuous driving force for the rotating assembly accurately and stably according to a preset periodic pattern, prompting the rotating assembly to drive the elastic surface 220 to rotate synchronously. Thus, it is possible to dissipate heat from every corner inside the electric control cabinet without dead angles, thereby further ensuring a comprehensive and efficient heat dissipation effect for the electric control cabinet.

[0088] It can be understood that the driving assembly can be a common driving form, such as an electric motor, an internal combustion engine, etc. The power source in the driving assembly can be centralized, and the power is transmitted to the rotating assembly through a transmission structure; the power source can also be decentralized, and multiple decentralized power sources respectively drive each rotating assembly to rotate.

[0089] Furthermore, the shockproof device 200 includes a plurality of pressure sensors, and the plurality of pressure sensors are used to make the driving assembly drive the rotating assembly to rotate after the elastic surface 220 is deformed and restored under an external load. Thus, it is possible to efficiently adjust the positions of the one-way plates 250 on the elastic surface 220 and improve the working efficiency of the driving assembly.

[0090] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0091] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
