Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch cabinets, in particular to a high-voltage switch cabinet with a heat dissipation function. Background Art

[0002] High-voltage switchgear refers to the switchgear used for on-off, control or protection in power generation, transmission, distribution, power conversion and consumption of power systems. The switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines and busbar connection. It is mainly suitable for various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mines, residential areas, high-rise buildings, etc.

[0003] The patent document with application number 201810131229.7 discloses a high-voltage switchgear with heat dissipation function, including a switchgear, the top of which is connected to a heat dissipation box, and a mesh plate is fixedly connected between the two sides of the inner cavity of the heat dissipation box, one side of the bottom of the inner cavity of the heat dissipation box is fixedly connected to a motor through a support platform, and the output shaft of the motor is fixedly connected to a turntable.

[0004] However, traditional high-voltage switchgear uses fixed-size ventilation holes and exhaust fans to dissipate heat, which may lead to low air flow in the cabinet and difficulty in quickly dissipating heat from the ventilation holes, resulting in poor heat dissipation effect. In addition, the surface area for ventilation and heat dissipation cannot be adjusted according to different occasions, which will also affect the performance and service life of electrical equipment in the cabinet. Utility Model Content

[0005] The utility model discloses a high-voltage switch cabinet with a heat dissipation function, which aims to solve the technical problems that traditional high-voltage switch cabinets use ventilation holes of fixed sizes with exhaust fans to dissipate heat, which may lead to low air flow in the cabinet, and heat is difficult to be quickly discharged from the ventilation holes, resulting in poor heat dissipation effect, and the surface area of ​​ventilation and heat dissipation cannot be adjusted according to different occasions, which will also affect the performance and service life of electrical equipment in the cabinet.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-voltage switch cabinet with a heat dissipation function comprises a cabinet body, wherein a first heat dissipation mechanism and a second heat dissipation mechanism are arranged inside the cabinet body, and further comprises:

[0008] Driving mechanism: the driving mechanism is fixedly connected to the top outer wall of the first heat dissipation mechanism;

[0009] The first heat dissipation mechanism includes a limiting assembly, two first brackets and two second brackets, one end of one of the first brackets is hinged to a mounting rod and a mounting pin is provided at the connection with the mounting rod, one side outer wall of one of the first brackets is hinged to a third bracket and a first connecting rod respectively, one end of the first connecting rod is hinged to a second connecting rod, one end of the second connecting rod is movably connected to one side outer wall of the mounting rod, one of the first brackets and one of the second brackets are hinged to each other, one side outer wall of one of the second brackets is hinged to a fourth bracket, and the top outer walls of the mounting rod, the third bracket, one of the first brackets and one of the second brackets are all fixedly connected to fan plates.

[0010] The above technical solution can enhance the heat dissipation effect. Specifically, the driving mechanism is used to control and drive the two first brackets and the two second brackets to move up and down at the same time, thereby driving the third bracket and the fourth bracket and the first connecting rod and the second connecting rod to move, thereby controlling the spacing between the fan plates, and also controlling the heat dissipation surface area of ​​the high-voltage switch cabinet. With the cooperation of the second heat dissipation mechanism, the heat inside the cabinet is blown out of the cabinet through the gaps between the fan plates, and the fan plates are driven to open and close continuously by the driving mechanism, which can guide the air flow and improve the ventilation efficiency of the cabinet. During the heat transfer process, the air flow can take away more heat, thereby enhancing the heat dissipation effect. The device has the function of controlling the ventilation area of ​​the cabinet according to different external temperature conditions, accelerating the airflow, enhancing the heat dissipation effect, having low manufacturing costs, and extending the service life of the high-voltage switch cabinet.

[0011] In a preferred solution, the limit assembly includes two fixed plates, the fixed plates are located on the bottom inner wall of the cabinet, and a limit slot is opened inside the fixed plates. One side outer wall of the first connecting rod and the second connecting rod, one side outer wall of the third bracket and one of the second brackets, one side outer wall of one of the first brackets and the fourth bracket, and both side outer walls of one of the second brackets are fixedly connected to a limit block, and the limit block is slidably connected to the inner wall of the limit slot.

[0012] Such an arrangement plays a certain limiting role in the up and down movement of the first heat dissipation mechanism, and the arranged limiting block slides in the limiting groove, thereby reducing the friction between the first heat dissipation mechanism and the limiting groove.

[0013] In a preferred embodiment, the driving mechanism includes a second motor, a mounting plate and a mounting plate, the mounting plate being fixedly connected to the top outer wall of the cabinet, the second motor being located on one side outer wall of the cabinet, the output shaft of the second motor passing through one side outer wall of the mounting plate and one end of the output shaft of the second motor being fixedly connected to a rotating block, the mounting plate being connected to one side outer wall of the mounting plate through a bearing, one side outer wall of the mounting plate being provided with a protrusion and a connecting frame, and the connecting frame being connected to one side outer wall of the mounting plate through a bearing, and two side inner walls of the connecting frame being movably connected with a moving rod, the bottom outer wall of the mounting plate being provided with a connecting plate, the moving rod passing through the top outer wall of the connecting plate and being fixedly connected with a mounting block, one side outer wall of the mounting block being respectively connected to two side outer walls of the two first brackets and two side outer walls of the two second brackets through bearings, a connecting block is sleeved on the outer wall located inside the connecting plate and on the outer wall of the moving rod, and a reset spring is provided on the top outer wall of the connecting block.

[0014] When in use, first start the second motor, and the output shaft of the second motor drives the rotating block to rotate, thereby pushing the protrusion to make a circular motion, and then drives the moving rod to reciprocate up and down. When the rotating block pushes the protrusion to reach the top of the disk, the moving rod drives the connecting block to squeeze the reset spring upward and compress the reset spring to the shortest. When the rotating block pushes the protrusion to the bottom of the disk, the reset spring recovers its deformation under the action of its own elastic force, and the reset spring acts downward to limit the connecting block.

[0024] The utility model discloses a high-voltage switch cabinet with a heat dissipation function, which is mainly used in traditional high-voltage switch cabinets that use ventilation holes of fixed sizes and exhaust fans to dissipate heat, which may lead to low air flow in the cabinet, and heat is difficult to be quickly discharged from the ventilation holes, resulting in poor heat dissipation effect, and the surface area for ventilation and heat dissipation cannot be adjusted according to different occasions, which will also affect the performance and service life of electrical equipment in the cabinet.

[0025] Reference Figure 1 , Figure 2 and Figure 3 A high-voltage switch cabinet with heat dissipation function comprises a cabinet body 1, wherein a first heat dissipation mechanism and a second heat dissipation mechanism are arranged inside the cabinet body 1, and further comprises:

[0026] Driving mechanism: The driving mechanism is fixedly connected to the top outer wall of the first heat dissipation mechanism;

[0027] The first heat dissipation mechanism includes a limiting assembly, two first brackets 8 and two second brackets 9, one end of one of the first brackets 8 is hinged with a mounting rod and a mounting pin is provided at the connection with the mounting rod, one side outer wall of one of the first brackets 8 is hinged with a third bracket 10 and a first connecting rod 16 respectively, one end of the first connecting rod 16 is hinged with a second connecting rod, one end of the second connecting rod is movably connected to one side outer wall of the mounting rod, one of the first brackets 8 and one of the second brackets 9 are hinged to each other, one side outer wall of one of the second brackets 9 is hinged with a fourth bracket 17, and the top outer walls of the mounting rod, the third bracket 10, one of the first brackets 8 and one of the second brackets 9 are fixedly connected with a fan plate 6.

This arrangement plays a certain limiting role in the up and down movement of the first heat dissipation mechanism, and the limit block 18 is set to slide in the limit groove 15 to reduce the friction between the first heat dissipation mechanism and the limit groove 15.

[0030] Among them, an installation opening is opened on the outer wall of one side of the cabinet 1, which is close to the first heat dissipation mechanism, and a first dustproof net 5 is provided on the inner wall of the installation opening. The first dustproof net 5 prevents dust from entering the cabinet 1 when the cabinet 1 is dissipating heat, thereby affecting the service life of some electronic components inside the cabinet 1.

[0031] Specifically, when the high-voltage switch cabinet needs to be cooled, the two first brackets 8 and the two second brackets 9 are first controlled and driven to move up and down at the same time through the driving mechanism. When the first bracket 8 and the second bracket 9 move up and down through the limit assembly, the third bracket 10 and the fourth bracket 17 as well as the first connecting rod 16 and the second connecting rod are driven to move, thereby controlling the distance between two adjacent fan plates 6, and then controlling the heat dissipation area of ​​the high-voltage switch cabinet.

[0034] Specifically, when in use, the second motor is started first, and the output shaft of the second motor drives the rotating block 20 to rotate, thereby pushing the protrusion 21 to make a circular motion, and then drives the moving rod 19 to reciprocate up and down. When the rotating block 20 pushes the protrusion 21 to the top of the disk, the moving rod 19 drives the connecting block 23 to squeeze the reset spring 13 upward, and compresses the reset spring 13 to the shortest. When the rotating block 20 pushes the protrusion 21 to the bottom of the disk, the reset spring 13 is restored to its original shape by its own elastic force, and the reset spring 13 acts downward to limit the connecting block 23.

[0038] Working principle: When the high-voltage switch cabinet needs to be cooled, the two first brackets 8 and the two second brackets 9 are first controlled and driven to move up and down at the same time through the driving mechanism.
