Description

Technical Field

[0001] The present application relates to the field of electric power equipment, and in particular to an intelligent electric distribution cabinet. Background Art

[0002] The distribution cabinet is an important part of the power system, used to distribute electrical energy and control power supply. However, when some distribution cabinets are placed outdoors, they are easily exposed to sunlight and heated, which not only affects the normal operation of the distribution cabinet, but also may cause equipment damage, thus affecting the stable operation of the entire power system.

[0003] In the prior art, a sunshade is installed on the power distribution cabinet to block the sunlight. However, the sunlight will shine obliquely, so that the upper part of the power distribution cabinet is in the shade, while the lower part of the power distribution cabinet is exposed to the sun, which makes it difficult to achieve a good sunshade effect on the power distribution cabinet. Summary of the invention

[0004] In order to improve the shading effect of the distribution cabinet, the present application provides an intelligent electrical distribution cabinet.

[0005] The present application provides an intelligent electrical distribution cabinet, which adopts the following technical solution: An intelligent electrical distribution cabinet comprises a cabinet body, wherein the cabinet body is matched with a cabinet door, the outer wall of the cabinet body is hollowly covered with a support frame, the top side of the cabinet body is provided with a first sun visor, support columns are fixedly installed between the corners of the top side of the support frame and the corners of the bottom side of the first sun visor, a plurality of second sun visors are rotatably installed between the support frame and the first sun visor, the cabinet body is installed with a driving mechanism, the driving mechanism is used to drive the second sun visors to rotate to block the sunlight shining on the cabinet body, a first temperature sensor is fixedly installed on the bottom side of the first sun visor, a controller is fixedly installed on the inner wall of the cabinet body, the first temperature sensor is used to generate a first temperature signal according to the temperature of the first sun visor and send it to the controller, and the controller is used to open and close the driving mechanism according to the first temperature signal.

[0006] By adopting the above technical solution, when the cabinet is irradiated by sunlight, the first sunshade blocks the sunlight from irradiating toward the top side of the cabinet, and the temperature of the first sunshade increases after being irradiated by sunlight. The first temperature sensor generates a first temperature signal according to the temperature of the first sunshade and sends it to the controller. When the first temperature signal exceeds a preset threshold, the controller drives the second sunshade to rotate through a driving mechanism so that one side of the second sunshade faces the cabinet. When one side of the second sunshade faces the cabinet, the second sunshade blocks the sunlight obliquely irradiated toward the side wall of the cabinet, thereby improving the shading effect on the power distribution cabinet.

[0007] At night or when the temperature is low due to sunlight, the temperature of the first sunshade decreases. When the first temperature signal is lower than a preset threshold, the controller drives the second sunshade to rotate through a driving mechanism, so that one side of the second sunshade faces the cabinet, thereby facilitating air circulation between two adjacent second sunshades, thereby facilitating heat dissipation of the cabinet.

[0008] Optionally, a first connecting rod is fixedly installed between the bottom surface of the first sun visor and the top side of the cabinet, a second connecting rod is fixedly installed between the inner wall of the support frame and the outer wall of the cabinet, the bottom side of the support frame is higher than the bottom side of the cabinet, the first sun visor is provided with a plurality of first vents, and a third sun visor is fixedly installed along one edge of the first vents of the first sun visor, and the third sun visor is inclined gradually away from the cabinet from one side connected to the first sun visor to the other side.

[0009] By adopting the above technical solution, the third sunshade plays a shading role, thereby reducing the situation where sunlight shines from the first vent to the top side of the cabinet. The first vent is arranged to facilitate air circulation, thereby facilitating heat dissipation of the cabinet. At the same time, air can also enter and exit from the space between the support frame and the cabinet, thereby facilitating heat dissipation of the cabinet.

[0010] Optionally, when the second sun visors rotate to block the sunlight shining towards the cabinet, each of the second sun visors is inclined gradually away from the cabinet from one side to the other side, and two adjacent second sun visors located on the same side of the cabinet are spaced and overlapped with each other, and a second vent is enclosed between two adjacent second sun visors located on the same side of the cabinet.

[0011] By adopting the above technical solution, when the driving mechanism drives the second sunshade to block the sunlight shining on the side wall of the cabinet, the overlapping parts of two adjacent second sunshades on the same side of the cabinet form a second vent. The heat emitted by the cabinet is discharged from the second vent, so that the cabinet can dissipate heat conveniently.

[0012] Optionally, a rotating rod is installed on the top side and the bottom side of the second sun visor, and the first sun visor and the support frame are both provided with a rotating hole for the rotating rod to be rotatably inserted.

[0013] By adopting the above technical solution, the rotating rod is inserted into the rotating hole, so that the second sun visor can be easily installed between the support frame and the first sun visor, and the second sun visor can be easily rotated between the support frame and the first sun visor.

[0014] Optionally, the driving mechanism includes a motor, a transmission belt, a first pulley and a second pulley, there are multiple first pulleys, and the first pulleys are arranged one by one corresponding to the second sun visor. The first pulley is fixedly installed on the rotating rod located on the bottom side of the second sun visor, the body of the motor is fixedly installed inside the cabinet, and the second pulley is fixedly installed on the rotating shaft of the motor. The transmission belt is arranged along the inside of the support frame, and the two ends of the transmission belt are fixedly passed through the inner wall of the support frame and the side wall of the cabinet and then enter the inside of the cabinet and connect with each other. The transmission belt bypasses the first pulley and the second pulley.

[0015] By adopting the above technical solution, the motor is started, and the motor drives the second pulley to rotate. The second pulley drives the first pulley to rotate through the transmission belt, and the first pulley drives the rotating rod to rotate, thereby facilitating the second sunshade to rotate.

[0016] Optionally, a mounting block is fixedly installed on one end of the rotating rod close to the second sun visor, and mounting grooves for the mounting block to pass through are provided on the top and bottom sides of the second sun visor, and an inlet and outlet connected to the mounting groove are provided on one side of the second sun visor, and the inlet and outlet are used for the mounting block to enter and exit the mounting groove. A driving rod is rotatably inserted into the side of the second sun visor with the inlet and outlet, and a shielding plate is fixedly installed on the driving rod, and the shielding plate is abutted against the side of the second sun visor with the inlet and outlet, and the shielding plate is used to shield the inlet and outlet.

[0017] By adopting the above technical solution, when it is necessary to install components inside the cabinet or to perform routine inspection on the components inside the cabinet, the driving rod is rotated, and the driving rod drives the shielding plate to leave the entrance and exit. Then, the second sun visor is pushed to make the installation block slide out of the entrance and exit, so as to facilitate the removal of the second sun visor. By removing the second sun visor from between the support frame and the first sun visor, it is convenient for the staff to open the cabinet door to inspect the inside of the cabinet.

[0018] After the inspection is completed, allow the installation block to enter the installation groove from the entrance, and then rotate the driving rod to allow the shielding plate to block the entrance, thereby facilitating the installation of the second sunshade between the support frame and the first sunshade.

[0019] Optionally, the top surface of the first sunshade is coated with a first reflective layer, and when the driving mechanism drives the second sunshade to block sunlight shining onto the cabinet, the side of the second sunshade facing away from the cabinet is coated with a second reflective layer.

[0020] By adopting the above technical solution, when sunlight shines, when the second sunshade blocks sunlight from shining on the side wall of the cabinet, the sunlight will shine on the first reflective layer and the second reflective layer. The sunlight is reflected by the first reflective layer and the second reflective layer, thereby reducing the heat absorbed by the first sunshade and the second sunshade, thereby reducing the temperature around the cabinet, and facilitating heat dissipation of the cabinet.

[0021] Optionally, a lifting frame is provided on the peripheral side of the cabinet, and a plurality of brush rods are installed on the inner wall of the lifting frame. The brush rods are elastic and are arranged one-to-one corresponding to the second sun visor. The brush rods are abutted against the second reflective layer, and the lifting frame is installed with a lifting mechanism, which is used to drive the lifting frame to lift and lower.

[0022] By adopting the above technical solution, the lifting mechanism drives the lifting frame to lift, and the lifting frame drives the brush rod to lift to clean the second reflective layer, thereby facilitating the cleaning of the second reflective layer. When the driving mechanism drives the sunshade to rotate, the brush rod is elastic, thereby facilitating the brush rod to stay against the second reflective layer.

[0023] Optionally, the lifting mechanism includes a lifting rope and a counterweight block, one end of the lifting rope is fixedly connected to the lifting frame, the other end of the lifting rope passes through the first sun visor from top to bottom and is connected to the counterweight block, and a water collecting trough is opened on the top side of the lifting frame.

[0024] By adopting the above technical solution, when it rains, rainwater enters the water collection tank. When the weight of the lifting frame is greater than the counterweight, the lifting frame moves downward. After the rainwater in the water collection tank evaporates, the weight of the lifting frame is less than the counterweight, so that the lifting frame moves upward under the pull of the counterweight, thereby facilitating the lifting frame to be lifted or lowered.

[0025] Optionally, a drain outlet is provided on the inner bottom wall of the water collection trough, and a guide rod is fixedly installed on the inner bottom wall of the water collection trough along the edge of the drain outlet. A sealing plate is provided inside the water collection trough, and the guide rod slides through the sealing plate. A top plate is fixedly installed on the peripheral side of the support frame, and the top plate is located directly below the drain outlet.

[0026] By adopting the above technical solution, after the lifting frame is lowered, the top plate enters the drain port and lifts up the blocking plate, thereby facilitating the rainwater inside the sump to be discharged from the drain port. After the rainwater is discharged from the drain port, the weight of the lifting frame is less than the counterweight block, so that the counterweight block drives the lifting frame to rise. After the lifting frame is lowered, the rainwater is discharged from the drain port, thereby facilitating the lifting frame to be repeatedly raised and lowered when it rains.

When there is sunlight, the first sunshade blocks the sunlight from shining on the top side of the cabinet, and the driving mechanism drives the second sunshade to rotate to block the sunlight from shining on the side wall of the cabinet, thereby improving the shading effect of the distribution cabinet; 2. The lifting mechanism drives the lifting frame to move up and down, and the lifting frame drives the brush rod to clean the second reflective layer, which is helpful to keep the second reflective layer clean for reflecting sunlight, thereby reducing the temperature around the cabinet and facilitating heat dissipation of the cabinet; BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 It is a schematic diagram of the overall structure of an embodiment of the present application; Figure 2 is a schematic diagram of the structure between the cabinet and the first sunshade of an embodiment of the present application; Figure 3 is a schematic structural diagram of a first sun visor according to an embodiment of the present application; Figure 4 This is a schematic diagram of the structure in which the support frame of the embodiment of the present application is installed on the cabinet; Figure 5 is an exploded view between the second sun visor and the rotating rod of an embodiment of the present application; Figure 6 is a top view of an embodiment of the present application; Figure 7 yes Figure 6 Sectional view at AA; Figure 8 is a schematic diagram of the structure between the driving mechanism and the rotating rod of an embodiment of the present application; Fig. 9 It is a schematic diagram of the structure between the lifting frame and the blocking plate of an embodiment of the present application.

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] The embodiment of the present application discloses an intelligent electrical distribution cabinet.

[0031] Reference Figure 1 , Figure 2, an intelligent electrical distribution cabinet, includes a cabinet body 1, and the cabinet body 1 is matched with a cabinet door 2. A first sun visor 3 is provided on the top side of the cabinet body 1, and a first connecting rod 5 is fixedly installed between the first sun visor 3 and the top side of the cabinet body 1. The first sun visor 3 is used to shade the sunlight shining on the top side of the cabinet body 1, thereby reducing the heating of the top side of the cabinet body 1 due to exposure to the sun. The first connecting rod 5 drives the first sun visor 3 to be separated from the top side of the cabinet body 1, thereby playing a heat insulating role. When the first sun visor 3 blocks the sunlight, the temperature of the first sun visor 3 rises. By separating the first sun visor 3 and the cabinet body 1, the speed at which the heat of the first sun visor 3 is transferred to the cabinet body 1 is slowed down.

[0032] Reference Figure 2 , Figure 3 The first sun visor 3 is provided with a plurality of first vents 7, and the first sun visor 3 is fixedly provided with a third sun visor 9 along one edge of the first vents 7. The third sun visor 9 is arranged to be inclined from one side connected to the first sun visor 3 to the other side gradually away from the cabinet 1. Air flows through the first vents 7, so that the cabinet 1 is convenient for heat dissipation. At the same time, the third sun visor 9 blocks sunlight, so as to reduce the situation where sunlight directly shines from the first vents 7 to the top side of the cabinet 1.

[0033] Reference Figure 4 A support frame 10 is provided below the first sun visor 3, and the support frame 10 is hollowly mounted in the cabinet 1. Support columns are fixedly installed between the corners of the support frame 10 and the corners of the first sun visor 3, and a second connecting rod 6 is fixedly installed between the inner wall of the support frame 10 and the outer wall of the cabinet 1. The support frame 10 is fixed by the support columns and the second connecting rod 6, so that the support frame 10 is conveniently installed on the cabinet 1. The bottom side of the support frame 10 is higher than the bottom side of the cabinet 1. Air enters and exits from the space between the support frame 10 and the cabinet 1, so that the cabinet 1 is convenient for heat dissipation.

[0034] Reference Figure 1 , Figure 5 A plurality of second sun visors 4 are rotatably mounted between the support frame 10 and the first sun visor 3 , and a rotating rod 11 is disposed on the top and bottom sides of the second sun visor 4 .

[0035] Reference Figure 4 , Figure 5A mounting block 12 is fixedly mounted on one end of the rotating rod 11 close to the second sun visor 4, and mounting grooves 13 for the mounting block 12 to pass through are provided on the top and bottom sides of the second sun visor 4. An inlet and outlet 14 connected to the mounting groove 13 is provided on one side of the second sun visor 4, and the mounting block 12 enters and exits the mounting groove 13 through the inlet and outlet 14. A driving rod 15 is rotatably plugged into the side of the second sun visor 4 with the inlet and outlet 14, and a shielding plate 16 is fixedly mounted on the driving rod 15. The shielding plate 16 is in contact with the side of the second sun visor 4 with the inlet and outlet 14. The first sun visor 3 and the support frame 10 are both provided with a rotating hole 17 for the rotating rod 11 to be rotatably plugged in.

[0036] Insert the rotating rod 11 into the rotating hole 17, and then rotate the driving rod 15 to drive the shielding plate 16 to leave the inlet and outlet 14. Then the mounting block 12 enters the inside of the mounting groove 13 from the inlet and outlet 14. After the mounting block 12 enters the inside of the mounting groove 13, the rotating driving rod 15 drives the shielding plate 16 to shield the inlet and outlet 14. The shielding plate 16 is used to limit the mounting block 12 from sliding out of the mounting groove 13 from the inlet and outlet 14, so as to facilitate the installation of the second sun visor 4 between the support frame 10 and the first sun visor 3.

[0037] When it is necessary to open the cabinet door 2 to inspect and repair the components inside the cabinet 1, the driving rod 15 is rotated to drive the shielding plate 16 to leave the inlet and outlet 14. Then the mounting block 12 slides out of the mounting groove 13 from the inlet and outlet 14, so as to facilitate the removal of the second sun visor 4 from between the first sun visor 3 and the support frame 10. After the second sun visor 4 is removed from between the first sun visor 3 and the support frame 10, the cabinet 1 has sufficient opening space, so that it is convenient for the staff to open the cabinet door 2 to inspect and repair the components inside the cabinet 1.

[0038] The rotating rod 11 cooperates with the rotating hole 17, and the rotating rod 11 can rotate. The mounting block 12 is clamped with the inner wall of the mounting groove 13, so that the second sun visor 4 can be rotated. When the sun is shining, the second sun visor 4 is rotated so that one side of the second sun visor 4 faces the cabinet 1, so that the second sun visor 4 can block the sunlight shining on the side wall of the cabinet 1. At night or when the intensity of sunlight is low, the second sun visor 4 is rotated so that one side of the second sun visor 4 faces the cabinet 1, so as to facilitate air circulation and heat dissipation of the cabinet 1.

[0039] Reference Figure 1 When the second sunshade 4 rotates to block the sunlight shining on the cabinet 1, each second sunshade 4 is inclined from one side to the other side and gradually moves away from the cabinet 1. Two adjacent second sunshades 4 on the same side of the cabinet 1 partially overlap each other, so that the second vent 8 is enclosed between the two second sunshades 4.

[0040] After the second sunshade 4 is rotated to block the sunlight shining on the cabinet 1, a second vent 8 is formed between two adjacent sunshades, so that the heat emitted by the cabinet 1 can be discharged from the second vent 8, thereby facilitating the heat dissipation of the cabinet 1.

[0041] Reference Figure 6 , Figure 7 , Figure 8 The cabinet 1 is provided with a driving mechanism 18 for driving the second sun visor 4 to rotate, and the driving mechanism 18 includes a motor 181, a transmission belt 182, a first pulley 183, and a second pulley 184. There are multiple first pulleys 183, and the first pulleys 183 are arranged one by one corresponding to the second sun visor 4. The first pulley 183 is fixedly mounted on the rotating rod 11 located at the bottom side of the second sun visor 4, the body of the motor 181 is fixedly mounted inside the cabinet 1, and the second pulley 184 is fixedly mounted on the rotating shaft of the motor 181. The transmission belt 182 is arranged along the inside of the support frame 10, and the two ends of the transmission belt 182 are fixedly passed through the inner side wall of the support frame 10 and the side wall of the cabinet 1, and then enter the inside of the cabinet 1 and connect with each other, and the transmission belt 182 bypasses the first pulley 183 and the second pulley 184. The motor 181 is started to rotate forward, and the motor 181 drives the rotating rod 11 to rotate through the first pulley 183, the second pulley 184 and the transmission belt 182, and the rotating rod 11 drives the second sunshade 4 to block the sunlight from irradiating the side wall of the cabinet 1. The motor 181 is started to rotate reversely, and the motor 181 drives the rotating rod 11 to rotate through the first pulley 183, the second pulley 184 and the transmission belt 182, and the rotating rod 11 drives one side of the second sunshade 4 toward the cabinet 1, so as to facilitate air circulation for heat dissipation of the cabinet 1.

[0042] In another embodiment, the transmission belt 182, the first pulley 183 and the second pulley 184 in the driving mechanism 18 can be replaced by a chain, a first gear and a second gear respectively.

[0043] Reference Figure 7 The transmission belt 182 is wrapped with a protective tube 19 between the support frame 10 and the cabinet 1. The protection tube 19 protects the transmission belt 182, thereby reducing the possibility of damage to the transmission belt 182 caused by sunlight exposure and rain erosion.

[0044] Reference Figure 2 , Figure 3A first temperature sensor 20 is fixedly installed on the bottom side of the first sun visor 3, and a controller 22 is fixedly installed on the inner wall of the cabinet 1. The controller 22 is used to open and close the drive mechanism 18, so that the motor 181 can be reversed or turned off. When sunlight shines on the cabinet 1, the first sun visor 3 blocks the sunlight from shining on the top side of the cabinet 1, thereby increasing the temperature of the first sun visor 3. The first temperature sensor 20 generates a first temperature signal according to the temperature of the first sun visor 3 and sends it to the controller 22. When the first temperature signal is greater than a preset threshold, the controller 22 starts the drive mechanism 18, so that when the cabinet 1 is exposed to sunlight, the drive mechanism 18 is automatically started, and the drive mechanism 18 drives the second sun visor 4 to rotate to block the sunlight.

[0045] At night, the temperature of the first sun visor 3 drops. When the first temperature signal is less than a preset threshold, the controller 22 starts the driving mechanism 18, thereby facilitating the automatic start of the driving mechanism 18 at night. The driving mechanism 18 drives one side of the second sun visor 4 toward the cabinet 1, and a space for air circulation is formed between two adjacent second sun visors 4, thereby facilitating heat dissipation of the cabinet 1.

[0046] Reference Figure 3 , Figure 5 , the top surface of the first sunshade 3 is coated with a first reflective layer 23. When the driving mechanism 18 drives the second sunshade 4 to block the sunlight shining on the cabinet 1, the second sunshade 4 is coated with a second reflective layer 24 on the side facing away from the cabinet 1. The sunlight is reflected by the first reflective layer 23 and the second reflective layer 24, thereby reducing the heat absorbed by the first sunshade 3 and the second sunshade 4, thereby reducing the temperature around the cabinet 1, and facilitating the heat dissipation of the cabinet 1.

[0047] Reference Figure 1 , Fig. 9 A lifting frame 25 is provided on the peripheral side of the cabinet 1, and the lifting frame 25 is located between the first sunshade 3 and the support frame 10, and the lifting frame 25 surrounds each second sunshade 4. The lifting frame 25 is provided with a lifting mechanism 26 for driving the lifting frame 25 to lift and lower, and the lifting mechanism 26 includes a suspension rope 261 and a counterweight block 262.

[0048] One end of the suspension rope 261 is fixedly connected to the lifting frame 25, and the other end of the suspension rope 261 passes through the first sun visor 3 from top to bottom and is connected to the counterweight 262. A water collecting tank 27 is provided on the top side of the lifting frame 25, and a drain port 28 is provided on the inner bottom wall of the water collecting tank 27. A guide rod 29 is fixedly installed on the inner bottom wall of the water collecting tank 27 along the edge of the drain port 28, and a blocking plate 30 is arranged inside the water collecting tank 27. The guide rod 29 slides through the blocking plate 30, and a top plate 31 is fixedly installed on the peripheral side of the support frame 10, and the top plate 31 is located directly below the drain port 28. A plurality of brush rods 32 are installed on the inner wall of the lifting frame 25, and the brush rods 32 are elastic. The brush rods 32 are arranged one by one corresponding to the second sun visor 4, and the brush rods 32 are pressed against the second reflective layer 24.

[0049] On rainy days, rainwater enters the water collection tank 27, so that the weight of the lifting frame 25 is greater than the counterweight 262, and the lifting frame 25 drives the brush rod 32 to descend. After the lifting frame 25 descends, the top plate 31 enters the drain port 28 to lift the blocking plate 30, and the rainwater in the water collection tank 27 is discharged from the drain port 28, so that the weight of the lifting frame 25 is less than the counterweight 262, and the counterweight 262 drives the lifting frame 25 to rise, and the lifting frame 25 drives the brush rod 32 to rise.

[0050] On rainy days, the lifting frame 25 is repeatedly lifted and lowered by the change of rainwater in the sump 27 , and the lifting frame 25 drives the brush rod 32 to clean the second reflective layer 24 , so that the second reflective layer 24 is kept clean for reflecting sunlight.

[0051] Reference Figure 2 The cabinet door 2 is provided with an air inlet 33 and an air outlet 34. An air inlet fan 35 is fixedly installed inside the air inlet 33, and a filter 36 is fixedly installed inside the air outlet 34. A mounting frame 37 is fixedly installed inside the cabinet 1, and a plurality of mounting plates 38 are installed on the mounting frame 37. The mounting plates 38 are used for installing components. A second temperature sensor 21 is fixedly installed inside the cabinet 1.

[0052] The second temperature sensor 21 detects the temperature inside the cabinet 1 to form a second temperature signal and sends it to the controller 22. When the second temperature signal is greater than a preset threshold, the controller 22 starts the fan. The fan drives air into the cabinet 1 from the air inlet 33, and the hot air inside the cabinet 1 is discharged from the air outlet 34, thereby facilitating the heat dissipation of the cabinet 1. When the second temperature signal is less than a preset threshold, the controller 22 turns off the fan, thereby achieving energy saving.

[0053] Reference Figure 7 Two heat pipes 39 are fixedly mounted on one side of the mounting plate 38. The two heat pipes 39 are gradually raised from one end close to the other end and are inclined. The heat pipes 39 are fixedly mounted with a plurality of fins 40. The heat emitted by the components inside the cabinet 1 is transferred to the fins 40, and the fins 40 transfer the heat to the heat pipes 39. The heat pipes 39 transport the heat from the low end to the high end for heat dissipation, thereby facilitating the uniform distribution of heat inside the cabinet 1, and further facilitating the second temperature sensor 21 to detect the temperature inside the cabinet 1.

[0054] The implementation principle of an intelligent electrical distribution cabinet in the embodiment of the present application is as follows: when the sun is shining, the first sunshade 3 blocks the sun from shining on the top side of the cabinet 1, the temperature of the first sunshade 3 gradually increases, and the first temperature sensor 20 generates a first temperature signal according to the temperature of the first sunshade 3 and sends it to the controller 22. When the first temperature signal is greater than a preset threshold, the controller 22 starts the motor 181, the motor 181 rotates forward, and the motor 181 drives each rotating rod 11 to rotate through the second pulley 184, the transmission belt 182 and the first pulley 183 in turn, and the rotating rod 11 drives one side of the second sunshade 4 to face the cabinet 1 to block the sunlight.

[0055] At night or on cloudy days, the temperature of the first sunshade 3 gradually decreases. When the first temperature signal is less than the preset threshold, the controller 22 starts the motor 181, and the motor 181 reverses. The motor 181 drives each rotating rod 11 to rotate through the second pulley 184, the transmission belt 182 and the first pulley 183 in turn. The rotating rod 11 drives one side of the second sunshade 4 toward the cabinet 1, thereby increasing the space between two adjacent second sunshades 4, thereby facilitating air circulation for heat dissipation of the cabinet 1.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
