Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with a temperature control structure. Background Art

[0002] As the power system becomes increasingly complex and key equipment has higher requirements for the operating environment, the stability and safety of the power distribution cabinet, as the core equipment for power distribution and management, are particularly important. When a traditional power distribution cabinet is in operation, the heat generated by the internal electrical equipment and the influence of the external environment often cause the temperature to rise, thus affecting the normal operation and life of the equipment. Therefore, a power distribution cabinet with a temperature control structure came into being to solve the thermal problem in power distribution and management; For example, in the prior art, there is a power distribution cabinet with a temperature regulation function, which is published as CN115693437B. The device monitors the temperature inside the power distribution cabinet by setting a temperature control element, and starts the device to cool down when the temperature rises. Timely cooling can increase the service life of electronic components, and suck out dust from the outer wall of the electronic components. In the process of sucking out dust, heat is also sucked out, which further accelerates the cooling of the electronic components and reduces damage to the electronic components. However, the device can only dissipate heat. When the temperature inside the power distribution cabinet is too low, the device cannot regulate the temperature inside the power distribution cabinet. In addition, during the heat dissipation process, excessive moisture inside the power distribution cabinet can easily damage the electronic components, and it is difficult to handle the excessive moisture. In view of the above technical defects, a solution is now proposed. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a power distribution cabinet with a temperature control structure, which forms an efficient heat dissipation effect on the temperature inside the cabinet through the temperature control mechanism, and uses activated carbon balls to absorb excess moisture to prevent the electronic components from being affected by excessive humidity in the air, and is equipped with a heat recovery component to recover the discharged heat. When the cabinet temperature is too low, the heat is discharged in time to maintain the internal temperature of the cabinet, thereby reducing energy consumption and maintaining the normal operation of electronic components, so as to solve the problems raised in the above-mentioned background technology.

[0005] Furthermore, the temperature control mechanism includes a motor fixed to the top of one side of the cabinet, and a rotating shaft that penetrates and extends to the inside of the cabinet is fixed on one side of the motor. Two second bevel gears are symmetrically sleeved at the outer sides of the rotating shaft corresponding to the positions on both sides of the inside of the cabinet, and a first bevel gear is meshed and rotatably connected below the second bevel gear. A screw rod rotatably connected to the inside of the cabinet is fixed to the bottom of the first bevel gear, and a connecting plate is sleeved on the outer layer of the screw rod, and a fixing block fixed to the inside of the cabinet is sleeved at the position below the outer layer of the screw rod corresponding to the connecting plate.

[0006] Furthermore, two isolation blocks are symmetrically fixed at the front and rear ends of the connecting plate, the bottom of the isolation block is an arc-shaped structure, and a filter frame is fixed to the bottom of the isolation block, one side of the filter frame is slidably connected to the position of the fixed block, a positioning plate is fixed to the outside of the sliding frame plate, and a limiting block is fixed to the side of the fixed block at the position of the positioning plate.

[0007] Furthermore, two storage bins are symmetrically opened on both sides of the inner top of the fixed block, a number of activated carbon balls are placed inside the storage bins, and the inner bottom layer of the storage bins is inclined to the horizontal direction, and a movable door is slidably connected to the position of the isolation block at one end of the storage bin, and the top of the movable door passes through and extends to the outside of the fixed block and is fixed to the bottom of the connecting plate, and recovery grooves are opened on both sides of the bottom of the fixed block corresponding to the position below the limit blocks, and bin doors are rotatably connected to the two sides of the cabinet corresponding to the position of the fixed block.

[0008] Furthermore, a bidirectional screw is sleeved at the middle position of the rotating shaft, two connecting rods are symmetrically sleeved on both sides of the outer layer of the bidirectional screw, and a cleaning roller is sleeved at the middle position of the outer layer of the bidirectional screw, and the top of the connecting rod is fixedly connected to the bottom side of the movable plate.

[0009] Furthermore, the heat recovery component includes a sliding rod sleeved on the outer layer of the bottom of the screw rod, the outer layer of the sliding rod is slidably sleeved with a sliding sleeve, a mounting frame is fixed between the two sliding sleeves, and a plurality of connecting pipes are equidistantly fixed inside the mounting frame.

[0010] Furthermore, a connecting pipe is fixed at the bottom of the bottom layer inside the cabinet at the position corresponding to the through hole, and the connecting pipe and the connecting pipe are connected to each other. A heat dissipation hole is opened on the upper surface of the thermal insulation airbag at the position corresponding to the connecting pipe, and two flip plates are symmetrically connected to the two sides of the heat dissipation hole for rotation.

[0011] Furthermore, two rotating plates are symmetrically rotatably connected on both sides of the upper surface of the heat-insulating airbag, one side of the rotating plate passes through and extends to the inside of both sides of the cabinet, and a groove is opened on the inner side wall of the cabinet at the position corresponding to the rotating plate.

[0012] Furthermore, an electric control button is fixed to the bottom of one side of the rotating plate, and limit plates are fixed on both sides of the interior of the cabinet at positions corresponding to the rotating plate. An electric control slot is provided at the top of the limit plate at a position corresponding to the electric control button.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, the temperature inside the cabinet is controlled by setting a temperature control mechanism. When the temperature inside the cabinet rises, the starting motor cooperates with the first bevel gear and the second bevel gear to drive the two screws to rotate. The rotation of the screws drives the two isolation blocks to rise through the connecting plate, and at the same time, the heat dissipation fan is started to extract the heat inside the cabinet. The extracted heat is first discharged to the inside of the thermal insulation airbag through the arc structure at the bottom of the isolation block. When the thermal insulation airbag is fully expanded, the motor is started again in conjunction with the heat recovery component. At this time, the isolation block continues to rise until the filter frame moves to the position of the ventilation window, and the activated carbon balls fall into the inside of the filter frame during the rising process of the filter frame, thereby forming a drying effect on the recovered heat and absorbing excess moisture in the air inside the cabinet. The inside of the cabinet is dried while the temperature is reduced to ensure the normal operation of the internal electronic components.

[0014] 2. In the present invention, when heat is dissipated, the motor drives the rotating shaft to rotate and drives the bidirectional screw to rotate at the same time. The rotation of the bidirectional screw drives the connecting rod to move, and then drives the two movable plates to move, so as to open the convection port and the ventilation window to form a convection effect, thereby forming a more efficient heat dissipation effect. At the same time, the rotation of the rotating shaft drives the cleaning roller to rotate to clean the filter screen, ensuring that the convection effect will not be affected.

[0015] 3. The present invention is provided with a heat recovery component. When the cabinet is cooled by the temperature control mechanism, the heat will be introduced into the interior of the thermal insulation airbag through the arc structure at the bottom of the isolation block in advance. When the thermal insulation airbag is fully expanded, the rotating plate flips and engages with the limit plate to form a seal. At the same time, the electric control button contacts the electric control slot to control the motor to start again and drive the isolation block to rise, thereby dissipating the heat to the outside of the cabinet. When the temperature inside the cabinet is too low, the start motor rotates in the opposite direction to drive the slide bar to descend. At this time, the mounting frame descends due to its own gravity and sticks to the thermal insulation airbag. The connecting pipe is inserted into the heat dissipation hole, and the heat inside the thermal insulation airbag is discharged into the cabinet, thereby avoiding the internal temperature of the cabinet being too low and effectively reducing the energy consumption required to maintain the cabinet temperature.

[0016] To summarize, the present invention relies on a temperature control mechanism to discharge and recover heat inside the cabinet, and uses activated carbon balls to absorb moisture inside the cabinet during the heat dissipation process, thereby drying the recovered heat, and cooperating with the top convection port to achieve efficient heat dissipation. At the same time, a heat recovery component is used to store the recovered heat, which is used for regulation when the cabinet temperature is too low, thereby reducing energy consumption and effectively ensuring that the electronic components inside the cabinet are always in a normal operating environment.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] This embodiment aims to address the problem that, in the prior art, power distribution cabinets mostly directly discharge heat to the outside of the cabinet during heat dissipation, which makes it impossible to effectively utilize the heat, resulting in a waste, and is unable to absorb and discharge the excessive humidity inside the cabinet.

[0021] like Figure 1-5 As shown, a power distribution cabinet with a temperature control structure includes a cabinet body 1, two cabinet doors 2 are rotatably connected to the front end of the cabinet body 1, and two groups of ventilation windows 4 are symmetrically opened on both sides of the cabinet body 1, and isolation blocks 23 are arranged at positions corresponding to the ventilation windows 4 on both sides of the cabinet body 1, and heat dissipation fans 7 are fixed at positions corresponding to the ventilation windows 4 on both sides of the cabinet body 1; A temperature sensor 43 is fixed to the rear end of the cabinet 1, and a convection port 9 is opened on the upper surface of the cabinet 1, a filter 10 is fixed inside the convection port 9, and two movable plates 6 slidably connected to the inside of the cabinet 1 are symmetrically arranged at the position above the filter 10 inside the convection port 9, and a temperature control mechanism 11 is installed between the movable plate 6, the isolation block 23 and the cabinet 1. The temperature control mechanism 11 includes a motor 5 fixed to the top of one side of the cabinet 1, and a rotating shaft 18 that penetrates and extends to the inside of the cabinet 1 is fixed to one side of the motor 5. A bidirectional screw rod 15 is sleeved at the middle position of the rotating shaft 18, and two connecting rods 12 are symmetrically sleeved on both sides of the outer layer of the bidirectional screw rod 15, and a cleaning roller 14 is sleeved at the middle position of the outer layer of the bidirectional screw rod 15, and the top of the connecting rod 12 is fixedly connected to one side of the bottom of the movable plate 6; Two isolation blocks 23 are symmetrically fixed at the front and rear ends of the connecting plate 19. The bottom of the isolation block 23 is an arc-shaped structure, and a filter frame 26 is fixed to the bottom of the isolation block 23. A sliding frame plate 24 is slidably connected to one side of the filter frame 26 at a position corresponding to the fixed block 29. The initial state of the sliding frame plate 24 and the filter frame 26 is in a semi-open structure. When the movable door 22 is opened to a height at which the activated carbon ball 21 can slide down, the sliding frame plate 24 and the filter frame 26 just form a closure. A positioning plate 28 is fixed to the outside of the sliding frame plate 24, and a limiting block 25 is fixed to the side of the fixed block 29 at a position corresponding to the positioning plate 28; Two storage bins 20 are symmetrically provided on both sides of the top of the fixed block 29. A plurality of activated carbon balls 21 are placed inside the storage bins 20. The bottom layer of the storage bins 20 is inclined with respect to the horizontal direction. Due to the inclined structure, when the movable door 22 is opened, the activated carbon balls 21 inside the storage bins 20 will slide down due to their own gravity. A movable door 22 is slidably connected to one end of the storage bin 20 at a position corresponding to the isolation block 23. The top of the movable door 22 penetrates and extends to the outside of the fixed block 29 and is fixed to the bottom of the connecting plate 19. Recovery grooves 27 are provided on both sides of the bottom of the fixed block 29 at positions corresponding to the limit blocks 25. The recovery groove 27 is located below the filter frame 26. The bottom layer inside the filter frame 26 is inclined to the horizontal direction. When the filter frame 26 returns to the initial state, the activated carbon balls 21 inside the filter frame 26 slide down and enter the fixed block 29 through the recovery groove 27 for recovery. The two sides of the cabinet 1 are rotatably connected to the fixed block 29. The used activated carbon balls 21 can be recovered by opening the bin door 3.

[0022] The temperature inside the cabinet 1 is monitored by the temperature sensor 43. When the temperature inside the cabinet 1 is too high, the temperature sensor 43 transmits a signal to the motor 5, and the motor 5 is started to drive the shaft 18 to rotate. The shaft 18 rotates to cooperate with the second bevel gear 17 and the first bevel gear 16 to drive the two screws 13 to rotate. The screws 13 rotate to drive the connecting plate 19 to rise. During the process of the connecting plate 19 rising, the isolation block 23 is driven to rise until the bottom arc structure is located at the position of the ventilation window 4, and then the heat dissipation fan 7 is started to absorb the heat inside the cabinet 1; When the connecting plate 19 is raised, the movable door 22 is also raised, and the activated carbon balls 21 in the storage bin 20 slide down. When the isolation block 23 is raised, the filter frame 26 is also raised. As the filter frame 26 rises, the sliding frame plate 24 forms a relative falling effect, thereby closing the filter frame 26. At this time, the sliding activated carbon balls 21 just fall into the filter frame 26. The heat sucked by the heat dissipation fan 7 is discharged downward through the arc structure. The heat passes through the filter frame 26 and the activated carbon balls 21 inside the filter frame 26 to achieve a drying effect. The dried heat enters the heat preservation airbag 32 to form a recycling effect. When the heat preservation airbag 32 is fully inflated, the motor 5 starts again to drive the rotating shaft 18 to rotate, and the isolation block 23 continues to rise until the filter frame 26 is located at the ventilation window 4. At this time, the heat inside the cabinet 1 is sucked by the heat dissipation fan 7 and directly discharged to the outside of the cabinet 1, thereby forming a cooling effect on the cabinet 1. Example

[0023] This embodiment is intended to address the problem of slow heat dissipation of the power distribution cabinet in the prior art.

[0024] like Figure 4 As shown, the embodiment is a power distribution cabinet with a temperature control structure, and a bidirectional screw rod 15 is sleeved at the middle position of the rotating shaft 18, two connecting rods 12 are symmetrically sleeved on both sides of the outer layer of the bidirectional screw rod 15, and a cleaning roller 14 is sleeved at the middle position of the outer layer of the bidirectional screw rod 15, the top end of the connecting rod 12 is fixedly connected to one side of the bottom of the movable plate 6, and a groove is opened on the top layer inside the cabinet body 1 corresponding to the connection between the connecting rod 12 and the movable plate 6.

[0025] When the starting motor 5 drives the rotating shaft 18 to rotate, it also drives the bidirectional screw 15 to rotate. The rotation of the bidirectional screw 15 drives the connecting rod 12 to move in opposite directions, thereby driving the movable plate 6 to move into the cabinet 1. At this time, the convection port 9 is in an open state. The rotation of the bidirectional screw 15 drives the cleaning roller 14 to continuously scrape the filter 10 to keep the filter 10 clean. When heat dissipation is performed, the ventilation windows 4 on both sides and the convection port 9 form a strong convection effect, thereby achieving a more efficient heat dissipation and ventilation effect. Example

[0026] This embodiment aims to address the problem in the prior art that the power distribution cabinet can only dissipate heat, and when the internal temperature of the power distribution cabinet is too low, the internal temperature of the power distribution cabinet cannot be regulated.

[0027] like Figure 6-9 As shown, the embodiment is a power distribution cabinet with a temperature control structure, and a plurality of through holes 35 are equidistantly opened on the inner bottom layer of the cabinet body 1, and a heat preservation airbag 32 is fixed on the inner bottom layer of the cabinet body 1, and a heat recovery component 8 is installed between the cabinet body 1 and the heat preservation airbag 32, and the heat recovery component 8 includes a slide rod 30 sleeved on the outer layer of the bottom of the screw rod 13. In the absence of any external force, when the screw rod 13 rotates, the slide rod 30 will not rotate with the rotation of the screw rod 13 due to the friction between its own gravity and the sliding sleeve 42, so it will rise due to the rotation of the screw rod 13. When the limit plate 33 is engaged with the electric control touch button 34, the rotation of the screw rod 13 will drive the slide rod 30 to rotate, so as not to affect the subsequent rotation of the screw rod 13. The outer layer of the slide rod 30 is slidably sleeved with a sliding sleeve 42, and a mounting frame 38 is fixed between the two sliding sleeves 42. A plurality of connecting pipes 36 are fixed equidistantly inside the mounting frame 38. A connecting pipe 39 is fixed at the position corresponding to the through hole 35 at the bottom of the bottom layer inside the cabinet 1. The connecting pipe 39 and the connecting pipe 36 are connected to each other. A limited sealing block is provided at the connection between the connecting pipe 36 and the connecting pipe 39. A heat dissipation hole 41 is provided at the upper surface of the heat preservation airbag 32 corresponding to the position of the connecting pipe 36. Two flip plates 40 are symmetrically connected to the heat dissipation hole 41 on both sides. A sealing groove is provided on the outer layer of the top of the flip plate 40. A sealing ring is fixed at the outer layer of the bottom end of the connecting pipe 36 corresponding to the sealing groove. The upper surface of the heat preservation airbag 32 Two rotating plates 37 are symmetrically connected to the two sides of the surface for rotation. The bottom of the rotating plate 37 is a hollow structure to avoid causing movement interference to the mounting frame 38. One side of the rotating plate 37 penetrates and extends to the inside of the two sides of the cabinet 1. A slot 31 is provided on the inner side wall of the cabinet 1 at the position corresponding to the rotating plate 37. An electric control touch button 34 is fixed to the bottom of one side of the rotating plate 37. A limit plate 33 is fixed at the position corresponding to the rotating plate 37 on both sides of the interior of the cabinet 1. An electric control slot is provided at the top of the limit plate 33 at the position corresponding to the electric control touch button 34.

[0028] When heat dissipation is performed, when the motor 5 is started and drives the isolation block 23 to rise, the screw rod 13 is rotated to drive the slide rod 30 to rise, and the slide rod 30 rises and cooperates with the sliding sleeve 42 to drive the mounting frame 38 to rise. At this time, the mounting frame 38 moves to a position below the bottom layer inside the cabinet 1 and is separated from the heat preservation airbag 32; As the heat dissipation fan 7 draws heat and discharges it into the heat preservation airbag 32, the heat preservation airbag 32 expands due to the continuous heat inflow, and the expansion of the heat preservation airbag 32 drives the top to continue to rise, and the rotating plate 37 turns over due to the continuous rise of the bottom. When the heat preservation airbag 32 is fully expanded, the rotating plate 37 just turns over to the horizontal position, and the limit plate 33 and the electric control touch button 34 just engage, thereby controlling the motor 5 to start again and drive the filter frame 26 to move to the position of the ventilation window 4; When the temperature sensor 43 detects that the temperature inside the cabinet 1 is too low, the motor 5 is started to rotate in the opposite direction. At this time, the screw rod 13 rotates in the opposite direction to drive the slide rod 30 to drop to the bottom. At this time, the mounting frame 38 drops due to its own gravity, and pushes the flip plate 40 to insert into the heat dissipation hole 41. At this time, the thermal insulation airbag 32 is connected to the inside of the cabinet 1, and the heat inside the thermal insulation airbag 32 is discharged to the inside of the cabinet 1, which effectively keeps the inside of the cabinet 1 from being too low and greatly saves the energy consumption required to maintain the temperature.

[0029] Working process and principle of the present invention: Step 1: The temperature inside the cabinet 1 is monitored by the temperature sensor 43. When the temperature inside the cabinet 1 is too high, the temperature sensor 43 transmits a signal to the motor 5, and the motor 5 is started to drive the rotating shaft 18 to rotate. The rotating shaft 18 rotates to cooperate with the second bevel gear 17 and the first bevel gear 16 to drive the two screw rods 13 to rotate. The rotation of the screw rod 13 drives the connecting plate 19 to rise. During the process of the connecting plate 19 rising, the isolation block 23 is driven to rise until the bottom arc structure is located at the position of the ventilation window 4, and then the heat dissipation fan 7 is started to absorb the heat inside the cabinet 1; When the connecting plate 19 is raised, the movable door 22 is also raised, and the activated carbon balls 21 in the storage bin 20 slide down. When the isolation block 23 is raised, the filter frame 26 is also raised. As the filter frame 26 rises, the sliding frame plate 24 forms a relative falling effect, thereby closing the filter frame 26. At this time, the sliding activated carbon balls 21 just fall into the filter frame 26. The heat sucked by the heat dissipation fan 7 is discharged downward through the arc structure. The heat passes through the filter frame 26 and the activated carbon balls 21 inside the filter frame 26 to achieve a drying effect. The dried heat enters the heat preservation airbag 32 to form a recycling effect. When the heat preservation airbag 32 is fully expanded, the motor 5 is started again to drive the rotating shaft 18 to rotate, and the isolation block 23 continues to rise until the filter frame 26 is located at the ventilation window 4. At this time, the heat inside the cabinet 1 is sucked by the heat dissipation fan 7 and directly discharged to the outside of the cabinet 1, thereby forming a cooling effect on the cabinet 1; Step 2: Start the motor 5 to drive the rotating shaft 18 to rotate, and at the same time drive the bidirectional screw rod 15 to rotate. The rotation of the bidirectional screw rod 15 drives the connecting rod 12 to move in opposite directions, thereby driving the movable plate 6 to move into the cabinet 1. At this time, the convection port 9 is in an open state. The rotation of the bidirectional screw rod 15 drives the cleaning roller 14 to continuously scrape the filter 10 to keep the filter 10 clean. When heat dissipation is performed, the ventilation windows 4 on both sides and the convection port 9 form a strong convection effect, thereby achieving a more efficient heat dissipation and ventilation effect; Step 3: When heat dissipation is performed, when the motor 5 is started to drive the isolation block 23 to rise, the screw rod 13 is rotated to drive the slide rod 30 to rise, and the slide rod 30 rises to cooperate with the sliding sleeve 42 to drive the mounting frame 38 to rise. At this time, the mounting frame 38 moves to a position below the bottom layer inside the cabinet 1 and is separated from the heat preservation airbag 32; As the heat dissipation fan 7 draws heat and discharges it into the heat preservation airbag 32, the heat preservation airbag 32 expands due to the continuous heat inflow, and the expansion of the heat preservation airbag 32 drives the top to continue to rise, and the rotating plate 37 turns over due to the continuous rise of the bottom. When the heat preservation airbag 32 is fully expanded, the rotating plate 37 just turns over to the horizontal position, and the limit plate 33 and the electric control touch button 34 just engage, thereby controlling the motor 5 to start again and drive the filter frame 26 to move to the position of the ventilation window 4; When the temperature sensor 43 detects that the temperature inside the cabinet 1 is too low, the motor 5 is started to rotate in the opposite direction. At this time, the screw rod 13 rotates in the opposite direction to drive the slide rod 30 to drop to the bottom. At this time, the mounting frame 38 drops due to its own gravity, and pushes the flip plate 40 to insert into the heat dissipation hole 41. At this time, the thermal insulation airbag 32 is connected to the inside of the cabinet 1, and the heat inside the thermal insulation airbag 32 is discharged to the inside of the cabinet 1, which effectively keeps the inside of the cabinet 1 from being too low and greatly saves the energy consumption required to maintain the temperature.

[0030] In summary, the temperature inside the cabinet 1 is monitored by the temperature sensor 43, and the excess heat inside the cabinet 1 is extracted and discharged by the temperature control mechanism 11, and the heat recovery component 8 is used to recover the heat. This allows the internal temperature of the cabinet 1 to be maintained and regulated in time when the internal temperature of the cabinet 1 is too low, so that the electronic components inside the cabinet 1 are always in the best operating environment.

[0031] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
