Description

Technical Field

[0001] This utility model relates to the field of radio power control technology, and in particular to a radio power control device. Background Technology

[0002] Radio power control devices monitor the operation of power distribution equipment by detecting the voltage, current, leakage current, etc. of the electricity distributed from the power distribution equipment, as well as the temperature of the transformer and whether the switches are open or closed. They also control the various operations of the power distribution equipment during safety inspections and when the equipment malfunctions or operates abnormally.

[0003] Chinese patent document with application number 202223198284.9 discloses a radio power control device: it is equipped with a moisture-proof mechanism. When the rain sensor detects rain outside, it drives the moisture-proof plate to move through an electric telescopic rod, so that the misaligned holes on the moisture-proof plate are misaligned with the ventilation holes, thereby closing the ventilation holes and preventing the outside humid air from entering the inside of the radio power control cabinet, thus improving the internal moisture-proof performance.

[0004] The device cannot perform drying due to heat dissipation. When the outside environment is humid, the heat dissipation effect of the control device will be greatly reduced. If the humid environment lasts for too long, the temperature of the internal components of the control device will rise, which will reduce the service life of its internal components under the action of high temperature. Utility Model Content

[0005] This invention provides a radio power control device to solve the problem in the prior art where prolonged exposure to humid environments causes the internal temperature components of the control device to rise, resulting in a reduced service life of the internal components under high temperatures.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A radio power control device, comprising:

[0008] The power control housing has a heat dissipation channel at its bottom for airflow.

[0009] Drying rack, which is installed inside the power control housing;

[0010] The drying rack includes:

[0011] Support columns, wherein multiple sets of support columns are provided;

[0012] A drying rack, wherein multiple drying racks are provided and the drying racks are installed between two adjacent sets of support columns;

[0013] The desiccant is placed on a drying rack, and the amount of desiccant on each adjacent pair is not the same;

[0014] It also includes: a heat sink, which is installed inside the power control housing and located on top of the drying rack;

[0015] A temperature sensor, which is fixed inside the power control housing;

[0016] A humidity sensor, which is fixed to the outside of the power control housing.

[0017] Optionally, the top of the drying rack is fixedly installed with a placement space for placing desiccant, and a pressure plate for pressing the desiccant is detachably fixedly installed at the top opening of the placement space.

[0018] Optionally, the drying rack further includes:

[0019] The receiving plate is provided in two parts, and the two receiving plates are respectively sleeved on the outside of the receiving columns at both ends;

[0020] A compression spring, which is fixed between the right end receiving plate and the inner wall of the power control housing;

[0021] The first telescopic rod is fixed between the left end receiving plate and the inner wall of the power control housing.

[0022] Optionally, the heat sink has multiple air ducts arranged in a rectangular array, and a second telescopic rod that is fixedly connected to the inner wall of the power control housing is fixedly installed at the right end of the heat sink.

[0023] Optionally, the lower surface of the heat sink is bonded with a sealing gasket that contacts the upper surface of the drying rack.

[0024] Optionally, a filter screen is detachably and fixedly installed at the opening of the heat dissipation channel, and the filter screen is located below the drying rack.

[0025] Optionally, two detachable baffles are fixedly installed on the inner walls of both sides of the power control housing, and the two baffles are in contact with the upper surface of the heat sink and the lower surface of the drying rack, respectively.

[0026] The beneficial effects of this utility model are:

[0027] The relative positions of the drying rack and the heat dissipation rack allow for adjustment of external humidity and internal temperature. When the internal temperature rises while the external humidity is normal, the air convection channel is widened to accelerate heat dissipation. When the internal temperature is normal while the external humidity is abnormal, a large amount of desiccant will block some of the air convection channels. As the air convects, it passes through the desiccant, thus drying the flowing gas while maintaining heat dissipation. When the internal temperature rises while the external humidity is abnormal, a small amount of desiccant will block some of the air convection channels, appropriately accelerating airflow while maintaining gas dryness.

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0040] Reference Figure 1-5 A radio power control device is shown, comprising:

[0041] The power control housing 100 has a heat dissipation channel 110 at its bottom for airflow, which ensures normal airflow.

[0042] Drying rack 200, which is installed inside the power control housing 100;

[0043] Drying rack 200 includes:

[0044] Support column 210, multiple sets of support columns 210 are provided;

[0045] A drying rack 220 is provided, and multiple drying racks 220 are provided, with each side of the drying rack 220 being fixedly connected to two adjacent sets of support columns 210.

[0046] Desiccant 230 is placed on the drying rack 220. The amount of desiccant 230 on each adjacent pair is not the same, so that the airflow speed is also different.

[0047] It also includes: a heat sink 300, which is installed inside the power control housing 100 and is located on top of the drying rack 200;

[0048] Temperature sensor 400 is fixed inside the power control housing 100 and is used to sense the internal temperature of the power control housing 100. Temperature sensor 400 can be a commercially available product.

[0049] Humidity sensor 500 is fixed on the outside of the power control housing 100 and is used to sense the external humidity of the power control housing 100. The humidity sensor 500 can be a commercially available product.

[0050] When the humidity sensor 500 and the temperature sensor 400 simultaneously detect that the temperature and humidity are rising at the same time, the corresponding drive structure will be activated to move the heat sink 300 and the drying rack 220 at the same time, so that a small amount of desiccant 230 corresponds to the through hole on the heat sink 300, and the gas is kept dry while the air flow is appropriately accelerated.

[0051] When the humidity sensor 500 and the temperature sensor 400 sense that the humidity is rising while the temperature remains constant, the heat sink 300 and the drying rack 220 remain in the initial stage and do not move, maintaining a higher level of dryness and reducing airflow.

[0052] When the humidity sensor 500 and the temperature sensor 400 sense that the humidity remains constant while the temperature rises, the corresponding drive structure is activated to move the heat sink 300, so that the desiccant 230 is misaligned with the through hole on the heat sink 300, thereby reducing the drying effect and increasing the air flow speed.

[0053] The relative positions of the drying rack 220 and the heat dissipation rack 300 can adjust the external humidity and internal temperature. When the internal temperature rises while the external humidity is normal, the air convection channel is enlarged to accelerate heat dissipation. When the internal temperature is normal while the external humidity is abnormal, a large amount of desiccant 230 will block part of the air convection channel. When the air convects, it passes through the desiccant 230, drying the flowing gas while maintaining heat dissipation. When the internal temperature rises while the external humidity is abnormal, a small amount of desiccant 230 will block part of the air convection channel, appropriately accelerating air flow while keeping the gas dry.

[0054] Among them, multiple drying racks 220 are connected by the setting of the support column 210, and the maximum heat dissipation can be maintained when the gap between the support column 210 corresponds to the channel on the heat dissipation rack 300.

[0055] The drying rack 220 ensures the proper placement of the desiccant 230.

[0056] In some embodiments of this utility model, in order to ensure the proper placement of the desiccant 230, refer to Figure 4 As shown, a placement space 240 for placing desiccant 230 is fixedly installed on the top of the drying placement rack 220, and the middle of the placement space 240 is vertically open. A pressure plate 250 for pressing the desiccant 230 is detachably fixedly installed at the top opening of the placement space 240.

[0057] The placement space 240 provides space for the placement of the desiccant 230, and the desiccant 230 is arranged in a ring shape so that air can come into contact with the desiccant 230 for drying during the flow process.

[0058] The desiccant 230 is pressed and fixed by the pressure plate 250.

[0059] In some embodiments of this utility model, in order to ensure the proper installation of the drying rack 220, refer to Figure 4 As shown, the drying rack 200 also includes:

[0060] There are two support plates 260, which are respectively sleeved on the outside of the support columns 210 at both ends.

[0061] Compression spring 270 is fixed between the right end receiving plate 260 and the inner wall of the power control housing 100, and compression spring 270 is always kept in a compressed state;

[0062] The first telescopic rod 280 is fixed between the left end receiving plate 260 and the inner wall of the power control housing 100.

[0063] When installing the drying rack 220, first squeeze the right end receiving plate 260 to compress the compression spring 270, then hold the drying rack 220 at the corresponding height, with the receiving column 210 corresponding to the receiving plate 260. Then release the force on the right end receiving plate 260, the force of the compression spring 270 will be released, and push the receiving plate 260 to fit onto the outside of the receiving column 210, and keep it in a compressed state.

[0064] When the first telescopic rod 280 starts to extend, it pushes the receiving plate 260 and the drying rack 220 to move, and squeezes the compression spring 270 when moving. When the first telescopic rod 280 starts to retract, the elastic force of the compression spring 270 is released, and pushes the receiving plate 260 and the drying rack 220 to return to their original positions.

[0065] The receiving plate 260 is connected to the receiving column 210, and the drying rack 220 is fixed.

[0066] The position of the drying rack 220 is adjusted according to changes in temperature and humidity by means of the first telescopic rod 280 and the compression spring 270.

[0067] In some embodiments of this utility model, in order to ensure normal airflow, refer to Figure 2 and Figure 3 As shown, the heat sink 300 has multiple air ducts 310 arranged in a rectangular array, and a second telescopic rod 320 is fixedly installed on the right end of the heat sink 300 and fixedly connected to the inner wall of the power control housing 100.

[0068] The air duct 310 ensures normal airflow and air convection for heat dissipation, and the top of the power control housing 100 is provided with a corresponding convection channel, which is driven by a fan to ensure normal airflow.

[0069] The second telescopic rod 320 is used to move and adjust the position of the heat sink 300 during startup.

[0070] In some embodiments of this utility model, reference is made to Figure 2 As shown, a sealing gasket 330 is bonded to the lower surface of the heat sink 300, which contacts the upper surface of the drying rack 220.

[0071] The sealing gasket 330 seals the contact area between the drying rack 220 and the heat sink 300, thereby reducing the relative wear between the drying rack 220 and the heat sink 300.

[0072] In some embodiments of this utility model, in order to prevent dust from entering, refer to Figure 5 As shown, a filter screen 120 is detachably and fixedly installed at the opening of the heat dissipation channel 110, and the filter screen 120 is located below the drying rack 220.

[0073] The filter 120 filters the airflow, preventing dust from entering the interior of the power control housing 100.

[0074] In some embodiments of this utility model, reference is made to Figure 5 As shown, two detachable baffles 130 are fixedly installed on the inner walls of both sides of the power control housing 100, and the two baffles 130 are in contact with the upper surface of the heat sink 300 and the lower surface of the drying rack 200, respectively.

[0075] The baffle plate 130 serves to limit and support the drying rack 200 and the heat dissipation rack 300, preventing them from shaking during movement and maintaining contact with the sealing gasket 330.

[0076] The working method of this utility model:

[0077] When the humidity sensor 500 and the temperature sensor 400 simultaneously detect an increase in both temperature and humidity, the humidity sensor 500 and the temperature sensor 400 will control the first telescopic rod 280 and the second telescopic rod 320 to start, causing the first telescopic rod 280 and the second telescopic rod 320 to push the drying rack 220 and the heat dissipation rack 300 to move respectively, so that a small amount of desiccant 230 corresponds to the air duct 310, thereby maintaining the dryness of the gas while appropriately accelerating the airflow.

[0078] When the humidity sensor 500 and the temperature sensor 400 sense an increase in humidity while the temperature remains constant, the heat sink 300 and the drying rack 220 remain in their initial state and do not move, maintaining a higher level of dryness and reducing airflow.

[0079] When the humidity sensor 500 and the temperature sensor 400 sense that the humidity remains constant while the temperature rises, the temperature sensor 400 will control the second telescopic rod 320 to move the heat sink 300, so that the desiccant 230 is misaligned with the air duct 310, thereby reducing the drying effect and increasing the air flow speed.

[0080] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
