Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device for a power equipment switch cabinet. Background Art

[0002] A power equipment switch cabinet is a device used in a power system to control, convert, distribute power and protect against electric current. It usually includes a circuit breaker, switches, protection and measurement devices, etc., and can achieve safe and efficient management of electric power. Switch cabinets are widely used in substations, distribution rooms, industrial and commercial buildings, etc., and are an essential part of the power system. According to the different operating voltages, switch cabinets can be divided into high-voltage switch cabinets and low-voltage switch cabinets. According to the structure and working principle, there can be different types, such as gas-insulated switchgear (GIS), ring main unit, dual-power transfer switch cabinet, etc. Electrical equipment (such as circuit breakers, transformers, contactors, etc.) in the switch cabinet will generate a large amount of heat during operation, so it is necessary to use it in conjunction with a heat dissipation device. However, there are still problems to be solved in the use of most heat dissipation devices for power equipment switch cabinets in the prior art.

[0003] Most heat dissipation devices for power equipment switch cabinets in the prior art use a cooling fan to circulate the air inside the power equipment switch cabinet for heat dissipation and temperature reduction. In order to ensure the stable and normal operation of the cooling fan, regular maintenance of the cooling fan is required. However, the fans of most heat dissipation devices for power equipment switch cabinets in the prior art are fixed to the outer shell of the power equipment switch cabinet by means of screws, making the operation of installing and disassembling the cooling fan relatively complicated, increasing the difficulty of maintenance work, and also affecting the efficiency of maintenance work to a certain extent. Therefore, it is necessary to design a heat dissipation device for a power equipment switch cabinet to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to provide a heat dissipation device for a power equipment switch cabinet.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A heat dissipation device for a power equipment switch cabinet, comprising a power equipment switch cabinet body. A bottom shell is fixedly connected to the bottom of the power equipment switch cabinet body, and a top shell is fixedly connected to the top of the power equipment switch cabinet body. Four guide rods are fixedly connected to both ends of the inner wall of one side of the bottom shell and the top shell. Two of the guide rods form a group, and the four guide rods at the same end are all sleeved with the same square frame. The square frame is slidably connected to the guide rods. Four limit rods arranged in a square layout are fixedly connected to the top of the square frame. Two of the limit rods at the same end are both sleeved with the same support plate. Positioning rods are fixedly connected to both ends of the top of the support plate. The two positioning rods are both sleeved with the same fixing plate. Threaded sleeves are fixedly connected to the top of both ends of the fixing plate. An intake fan is arranged on the top of the two fixing plates at the same end and located at the bottom, and an exhaust fan is arranged on the top of the two fixing plates at the same end and located at the top.

The slide rods are slidably connected to the slide rails. The slide rail at the bottom is fixedly connected to the inner wall of the bottom of the bottom shell, and the slide rail at the top is fixedly connected to the inner wall of the bottom of the top shell. Since the technical means that the intake fan and the heat dissipation fan can descend a certain distance during the process of pulling out the square frame is adopted, when the intake fan descends a certain distance, it no longer contacts the bottom of the power equipment switch cabinet body, and when the exhaust fan descends a certain distance, it no longer contacts the inner wall of the top of the top shell. Then the fixing plate can be removed from the positioning rod, and thus the intake fan and the exhaust fan can be removed.

This effectively solves the problem in the background technology that in the prior art, most of the fans of the heat dissipation devices for power equipment switch cabinets are fixed on the outer shell of the power equipment switch cabinet by screws, which makes the operation of installing and disassembling the heat dissipation fans relatively complicated, increases the difficulty of maintenance work, and also affects the efficiency of maintenance work to a certain extent. Furthermore, the technical effects of simple operation, reducing the difficulty of maintenance work, and improving the efficiency of maintenance work are achieved.

[0007] As a further solution of the present invention, square openings are formed in both the bottom shell and the top shell, and a filter screen is installed at the position where the square opening is formed in the bottom shell.

[0008] As a further solution of the present utility model, ventilation openings are provided at both the bottom and the top of the main body of the power equipment switch cabinet.

[0009] As a further solution of the present utility model, cabinet doors are installed on the same side of the bottom shell and the top shell through hinges.

A second square plate is fixedly connected to the side of the round rod away from the round plate. The second square plate is fixedly connected to a square frame.

[0011] As a further solution of the present utility model, the round rod is slidably connected to the sleeve plate.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model: due to the technical means that the intake fan and the exhaust fan can be lowered by a certain distance during the process of pulling out the square frame, when the intake fan is lowered by a certain distance, it no longer contacts the bottom of the main body of the power equipment switch cabinet, and when the exhaust fan is lowered by a certain distance, it no longer contacts the inner wall of the top of the top shell. Then the fixing plate can be removed from the positioning rod, and thus the intake fan and the exhaust fan can be removed. When performing the installation work, the fixing plate is sleeved on the positioning rod, and then the square frame is moved back to the initial position, so that the intake fan and the exhaust fan can be raised by a certain distance to respectively contact the bottom of the main body of the power equipment switch cabinet and the inner wall of the top of the top shell for pressing and fixing. This effectively solves the problem in the background technology that in the prior art, most of the fans of the heat dissipation devices for power equipment switch cabinets are fixed to the outer shell of the power equipment switch cabinet by means of screws, which makes the operation of installing and disassembling the heat dissipation fans relatively complicated, increases the difficulty of the overhaul and maintenance work, and also affects the efficiency of the overhaul and maintenance work to a certain extent. Furthermore, the technical effects of simple operation, reducing the difficulty of the overhaul and maintenance work, and improving the efficiency of the overhaul and maintenance work are achieved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Next, the present utility model will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0023] Refer to Figures 1-6, A heat dissipation device for a power equipment switch cabinet, comprising a power equipment switch cabinet body 1. A bottom shell 2 is fixedly connected to the bottom of the power equipment switch cabinet body 1, and a top shell 3 is fixedly connected to the top of the power equipment switch cabinet body 1. Four guide rods 4 are fixedly connected to both ends of the inner wall on one side of the bottom shell 2 and the top shell 3. Two guide rods 4 form a group, and the four guide rods 4 at the same end are all sleeved with the same square frame 5. The square frame 5 is slidably connected to the guide rods 4. Four limit rods 6 arranged in a square layout are fixedly connected to the top of the square frame 5. Two limit rods 6 at the same end are all sleeved with the same support plate 7. Positioning rods 8 are fixedly connected to both ends of the top of the support plate 7. The two positioning rods 8 are both sleeved with the same fixing plate 9. Threaded sleeves 10 are fixedly connected to the top ends of both ends of the fixing plate 9. An intake fan 11 is provided on the top of the two fixing plates 9 located at the bottom and at the same end, and an exhaust fan 12 is provided on the top of the two fixing plates 9 located at the top and at the same end. A number of mounting holes are provided on both the intake fan 11 and the exhaust fan 12. The threaded sleeves 10 are adapted to the mounting holes on the intake fan 11 and the exhaust fan 12. The intake fan 11 is fixedly connected to the threaded sleeve 10 by screws, and the exhaust fan 12 is fixedly connected to the threaded sleeve 10 by screws. First square plates 13 are fixedly connected to the tops of the two support plates 7 at the same end and at the ends away from each other. Slide rods 14 are fixedly connected to the sides of the two first square plates 13 away from each other. The slide rods 14 are sleeved with slide rails 15. The slide rods 14 are slidably connected to the slide rails 15. The slide rail 15 at the bottom is fixedly connected to the inner bottom wall of the bottom shell 2, and the slide rail 15 at the top is fixedly connected to the inner bottom wall of the top shell 3. Due to the technical means that the intake fan and the heat dissipation fan can be lowered by a certain distance during the process of pulling out the square frame, when the intake fan is lowered by a certain distance, it will no longer contact the bottom of the power equipment switch cabinet body, and when the exhaust fan is lowered by a certain distance, it will no longer contact the inner top wall of the top shell. Then the fixing plate can be removed from the positioning rod, and thus the intake fan and the exhaust fan can be removed. When performing the installation work, the fixing plate is sleeved on the positioning rod, and then the square frame is moved back to the initial position, so that the intake fan and the exhaust fan can be raised by a certain distance to respectively contact the bottom of the power equipment switch cabinet body and the inner top wall of the top shell for pressing and fixing. This effectively solves the problem in the background technology that in the prior art, most of the fans of the heat dissipation devices for power equipment switch cabinets are fixed to the outer shell of the power equipment switch cabinet by screw fixing methods, which makes the operations of installing and disassembling the heat dissipation fans relatively complicated, increases the difficulty of maintenance work, and also affects the efficiency of maintenance work to a certain extent. Furthermore, it realizes the technical effects of simple operation, being able to reduce the difficulty of maintenance work, and being able to improve the efficiency of maintenance work.

[0024] In this embodiment, square openings are provided on both the bottom housing 2 and the top housing 3, and a filter screen 16 is installed at the square opening provided on the bottom housing 2.

[0025] In this embodiment, ventilation openings are provided at both the bottom and the top of the power equipment switch cabinet body 1.

[0026] In this embodiment, cabinet doors are installed on the same side of the bottom housing 2 and the top housing 3 through hinges.

[0027] In this embodiment, sleeve plates 21 are fixedly connected to the bottom inner walls of the bottom housing 2 and the top housing 3. A round rod 18 passes through the sleeve plates 21. A round plate 19 is fixedly connected to one side of the round rod 18. A spring 20 is sleeved on the round rod 18. A second square plate 17 is fixedly connected to the side of the round rod 18 away from the round plate 19, and the second square plate 17 is fixedly connected to the square frame 5.

[0028] In this embodiment, the round rod 18 is slidably connected to the sleeve plate 21.

[0029] Working principle: When using this device, the intake fan 11 and the exhaust fan 12 can be started. The intake fan 11 will suck the external cold air into the main body 1 of the power equipment switch cabinet, and the exhaust fan 12 will discharge the hot air inside the main body 1 of the power equipment switch cabinet, thereby circulating the air inside the main body 1 of the power equipment switch cabinet, reducing the temperature inside the main body 1 of the power equipment switch cabinet for heat dissipation. By setting the filter screen 16, the air sucked into the main body 1 of the power equipment switch cabinet can be filtered to prevent particulate impurities such as dust from entering the main body 1 of the power equipment switch cabinet. After a period of use, the intake fan 11 and the exhaust fan 12 need to be repaired and maintained to ensure that the intake fan 11 and the exhaust fan 12 can work stably and the heat dissipation function is normal. When repairing and maintaining the intake fan 11 and the exhaust fan 12, the intake fan 11 and the exhaust fan 12 need to be removed. At this time, the cabinet doors of the bottom shell 2 and the top shell 3 can be opened. Then the staff can pull the square frame 5 to move the square frame 5 out of the bottom shell 2 and the top shell 3 gradually. When the square frame 5 moves, it will drive the limit rod 6 to move. When the limit rod 6 moves, it will drive the support plate 7 to move. When the support plate 7 moves, it will drive the positioning rod 8 to move. The positioning rod 8 will drive the fixing plate 9 to move. The fixing plate 9 will drive the threaded sleeve 10 to move. The threaded sleeve 10 will drive the screw to move to move the intake fan 11 and the exhaust fan 12, and gradually move them out of the bottom shell 2 and the top shell 3. During the process of moving the square frame 5, the square frame 5 will also drive the second square plate 17 to move. The second square plate 17 will drive the round rod 18 to move. The round rod 18 will drive the round plate 19 to move. The round plate 19 will squeeze the spring 20 to make the spring 20 contract. During the process of moving the support plate 7, it will also drive the first square plate 13 to move. The first square plate 13 will drive the sliding rod 14 to move along the slide rail 15. When the sliding rod 14 continues to move when it moves to the guiding groove of the slide rail 15, the tops of the intake fan 11 and the exhaust fan 12 will gradually move away from the top inner wall of the bottom shell 2 and the top shell 3 and no longer contact the top inner wall of the bottom shell 2 and the top shell 3. Move the square frame 5 until the sliding rod 14 moves into the guiding groove at the lower end of the slide rail 15, then the fixing plate 9 can be removed from the positioning rod 8, and the intake fan 11 and the exhaust fan 12 can be removed, and the intake fan 11 and the exhaust fan 12 can be repaired and maintained. After the repair and maintenance are completed, pull out the square frame 5 again, align the positioning hole on the fixing plate 9 with the positioning rod 8, and put the fixing plate 9 on the positioning rod 8 again. Release the square frame 5, and the spring 20 will stretch out, enabling the square frame 5 to move. During the process of moving the square frame 5, the staff can push the square frame 5 for assistance. When the sliding rod 14 moves from the inclined guiding groove of the slide rail 15 to the higher guiding groove, the intake fan 11 and the exhaust fan 12 can be gradually lifted until the intake fan 11 touches the bottom of the main body 1 of the power equipment switch cabinet and the exhaust fan 12 touches the top inner wall of the top shell 3.By pressing the fixed plate 9 with the pallet 7, the fixed plate 9 then presses the intake fan 11 and the exhaust fan 12 against the bottom of the power equipment switchgear body 1 and the top inner wall of the top shell 3 respectively, so that the intake fan 11 and the exhaust fan 12 can be fixed and can be used normally. When the spring 20 extends, it can ensure that the sliding rod 14 is in the higher guide groove on the slide rail 15, so as to ensure the stable positions of the intake fan 11 and the exhaust fan 12.

[0030] For the sake of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation depicted in the figure.
