Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to a switch cabinet heat dissipation device with automatic temperature control. Background Art

[0002] The radiator is an important part of the switch cabinet. In the power system, if the heat cannot be dissipated in time, the temperature of the disconnector will be too high, causing the reliability of the equipment to decrease, and even causing failures. Therefore, it is necessary to set a heat dissipation mechanism with temperature automatic control related functions on the switch cabinet, and monitor the temperature through the internal temperature sensor. When the temperature is abnormal, the controller controls the cooling fan to start to dissipate heat to achieve the effect of automatic temperature control.

[0003] However, the existing switch cabinet cooling equipment with automatic temperature control has a fixed position of the cooling fan, which can only cool a certain area of ​​the switch cabinet, and the cooling area of ​​the cooling fan cannot be flexibly adjusted. Therefore, when the temperature is controlled, it cannot be ensured that the temperature of all areas in the switch cabinet can quickly return to normal, resulting in poor temperature control effect of the switch cabinet. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a switch cabinet heat dissipation device with automatic temperature control, which effectively solves the problem that the position of the cooling fan in the prior art is fixed, and it can only dissipate heat to a certain area of ​​the switch cabinet, and the cooling area of ​​the cooling fan cannot be flexibly adjusted. Therefore, when temperature control is performed, it is impossible to ensure that the temperature of all areas in the switch cabinet can quickly return to normal, resulting in poor temperature control effect of the switch cabinet.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A switch cabinet heat dissipation device with automatic temperature control, comprising a control box fixedly connected to the outer wall of the bottom of the switch cabinet body, the inner space of the switch cabinet body is divided into four electrical component installation rooms by four partition plates, and also comprises a position-adjustable air blowing mechanism;

[0007] The four electrical component installation rooms are all provided with a window heat dissipation mechanism, and the window heat dissipation mechanism includes a temperature sensor fixedly installed on the inner wall of the back of the electrical component installation room, two vents sequentially opened on both sides of the electrical component installation room, and two electric shutter structures sequentially installed at the two vents;

[0008] The position-adjustable air blowing mechanism comprises a driving assembly, a fixing frame fixedly connected to the side wall of the switch cabinet body, a vertical screw rotatably installed in the fixing frame, a sliding plate threadedly connected to the middle of the vertical screw, and two cooling fans installed on the sliding plate.

[0009] As a preferred technical solution of the present invention, the electric shutter structure includes five rotating shafts rotatably installed in the vent, five sealing blades fixedly connected to the five rotating shafts in sequence, five transmission gears fixedly mounted on the outer ends of the five rotating shafts in sequence, five racks meshed with the five transmission gears in sequence, a servo electric push rod fixedly installed on the outer wall of the back side of the switch cabinet body, and a connecting rod fixedly connected to the telescopic end of the servo electric push rod.

[0010] As a preferred technical solution of the present invention, the five racks are all fixedly connected to the connecting rod, the five sealing blades are all located in the vent, and the sizes of the five sealing blades are all adapted to the size of the vent.

[0011] As an optimal technical solution of the present invention, the driving assembly includes a fixed cover fixedly connected to the top outer wall of the fixed frame, a stepper motor fixedly installed on the outer wall of one side of the fixed cover, an active bevel gear fixedly mounted on the output shaft of the stepper motor, and a driven bevel gear fixedly mounted on the top of the vertical screw.

[0012] As a preferred technical solution of the present invention, the output shaft of the stepper motor passes through one side of the fixed cover, and the driving bevel gear and the driven bevel gear are meshed with each other and are both located in the fixed cover.

[0013] As a preferred technical solution of the present invention, two guide vertical shafts are symmetrically welded in the fixed frame, two guide holes are provided on the sliding plate, and the two guide holes are slidably connected to the two guide vertical shafts respectively.

[0014] As a preferred technical solution of the present invention, a cabinet door is hinged on the front side of the switch cabinet body, and a lockable handle is installed on the cabinet door.

[0015] The beneficial effects of the present invention are:

[0016] When the heat dissipation device of the present invention automatically controls the temperature of the switch cabinet, it can better feed back the temperature conditions of different areas in the switch cabinet to the control box by performing temperature zone monitoring. Subsequently, since the position-adjustable blower mechanism can flexibly adjust the heat dissipation areas of the two heat dissipation fans, the control box will perform temperature control one by one in a priority manner according to the temperature conditions of each area, thereby ensuring that the temperatures of all areas in the switch cabinet can quickly return to normal, effectively improving the temperature control effect of the switch cabinet; in addition, after the temperature control of each electrical component installation room of the present invention is completed, the two electric shutter structures can be automatically closed, thereby preventing external dust from entering the switch cabinet and causing adverse effects.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1, reference Figure 1-4, a switch cabinet heat dissipation device with automatic temperature control, comprising a control box 1 fixedly connected to the outer wall of the bottom of the switch cabinet body 2, the internal space of the switch cabinet body 2 is divided into four electrical component installation rooms 4 by four partition plates 3, the front of the switch cabinet body 2 is hinged with a cabinet door 21, and the cabinet door 21 is equipped with a lockable handle;

[0027] In this embodiment, the four electrical component installation rooms 4 are all provided with a window heat dissipation mechanism, which includes a temperature sensor 5 fixedly installed on the inner wall of the back of the electrical component installation room 4, two vents sequentially opened on both sides of the electrical component installation room 4, and two electric shutter structures sequentially installed at the two vents;

[0028] Specifically, the electric shutter structure includes five rotating shafts 6 rotatably installed in the vent, five sealing blades 7 fixedly connected to the five rotating shafts 6 in sequence, five transmission gears 8 fixedly sleeved on the outer ends of the five rotating shafts 6 in sequence, five racks 9 meshed with the five transmission gears 8 in sequence, a servo electric push rod 10 fixedly installed on the outer wall of the back side of the switch cabinet body 2, and a connecting rod 11 fixedly connected to the telescopic end of the servo electric push rod 10;

[0029] Furthermore, the five racks 9 are fixedly connected to the connecting rod 11, the five sealing blades 7 are located in the vent, the sizes of the five sealing blades 7 are adapted to the size of the vent, and all the servo electric push rods 10 and all the temperature sensors 5 are electrically connected to the control box 1;

[0030] The switching mode of the electric shutter structure is as follows: when the window needs to be opened for heat dissipation, the telescopic end of the servo electric push rod 10 drives all the racks 9 connected to the connecting rod 11 to move forward to make all the transmission gears 8 rotate in the positive direction, thereby driving the positive rotation of each transmission gear 8 to drive each sealing blade 7 on each rotating shaft 6 to rotate forward by ninety degrees synchronously to achieve opening; when the window needs to be closed to prevent dust, the telescopic end of the servo electric push rod 10 drives all the racks 9 connected to the connecting rod 11 to reset backward to make all the transmission gears 8 rotate in the opposite direction, thereby driving the reverse rotation of each transmission gear 8 to drive each sealing blade 7 on each rotating shaft 6 to rotate in the opposite direction by ninety degrees synchronously to achieve closing.

[0031] Example 2, reference Figure 1 , Figure 3 and Figure 5-6 , this embodiment is optimized on the basis of embodiment 1, specifically: a switch cabinet heat dissipation device with automatic temperature control, further comprising a position-adjustable blower mechanism;

[0032] Specifically, the position-adjustable air blowing mechanism includes a driving assembly, a fixing frame 12 fixedly connected to the side wall of the switch cabinet body 2, a vertical screw 13 rotatably installed in the fixing frame 12, a sliding plate 14 threadedly connected to the middle of the vertical screw 13, and two cooling fans 15 installed on the sliding plate 14;

[0033] Furthermore, the driving assembly includes a fixed cover 16 fixedly connected to the top outer wall of the fixed frame 12, a stepper motor 17 fixedly installed on the outer wall of one side of the fixed cover 16, a driving bevel gear 18 fixedly sleeved on the output shaft of the stepper motor 17, and a driven bevel gear 19 fixedly sleeved on the top of the vertical screw 13;

[0034] Furthermore, the output shaft of the stepper motor 17 passes through one side of the fixed cover 16, the active bevel gear 18 and the driven bevel gear 19 mesh with each other and are both located in the fixed cover 16, and the stepper motor 17 is electrically connected to the control box 1, that is, the control box 1 controls the stepper motor 17;

[0035] Furthermore, two guide vertical shafts 20 are symmetrically welded in the fixed frame 12, and two guide holes are provided on the sliding plate 14, and the two guide holes are respectively slidably connected with the two guide vertical shafts 20, and the stability of the linear motion of the sliding plate 14 can be ensured through the guiding effect of the two guide vertical shafts 20;

[0036] In the specific implementation of this embodiment: the vertical screw 13 is driven to rotate by the stepper motor 17, and then under the guidance of the two guide vertical shafts 20, the sliding plate 14 threadedly connected to the vertical screw 13 will drive the two cooling fans 15 to move in the vertical direction, so that the cooling area of ​​the two cooling fans 15 can be flexibly adjusted.

[0037] The use process of the present invention is as follows: first, each temperature sensor 5 monitors the temperature in the electrical component installation room 4 in real time, and feeds back the temperature signal in each area to the control box 1, thereby achieving the effect of temperature zone monitoring;

[0038] Secondly, the temperature control is to control the two electric shutter structures to open for heat dissipation through the control box 1, and the control box 1 will also control the two cooling fans 15 to run to further improve the heat dissipation efficiency;

[0039] Finally, during the temperature control process, since the position-adjustable blower mechanism can flexibly adjust the heat dissipation areas of the two heat dissipation fans 15, the control box 1 will perform temperature control one by one in a priority manner according to the temperature conditions of each area.
