Description

Technical Field

[0001] This invention relates to the field of switchgear equipment technology, specifically to an intelligent heat dissipation type removable high-voltage switchgear. Background Technology

[0002] A withdrawable high-voltage switchgear is an electrical device used in power systems to receive and distribute high-voltage electrical energy. Its core feature is that the switching elements (such as circuit breakers) can be removed from the cabinet. This design allows the switching elements to be pulled out of their working position without disconnecting the power supply during inspection, maintenance, or replacement, improving operational safety and facilitating equipment maintenance.

[0003] The switch cabinet generates heat due to the operation of its components. Existing conventional heat dissipation equipment uses fans to blow away the internal heat. However, conventional air blowing heat dissipation has a fixed air source position. Since the heat generated inside the switch cabinet is generated by various components, the heat source position will often be different due to the heat generated by different components. The fixed air source cannot be targeted to blow air, resulting in poor heat dissipation effect. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent heat dissipation type removable high-voltage switchgear to solve the problem mentioned in the background art that traditional fan cooling is difficult to target heat dissipation, resulting in poor heat dissipation effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent heat-dissipating removable high-voltage switchgear, comprising a switchgear frame and a mounting plate fixed within the switchgear frame. Heat dissipation fins are mounted on the mounting plate. A blower pipe and a suction pipe are fixed to both sides of the switchgear frame, respectively. Air holes are provided on the blower pipe and the suction pipe, and an air pipe is fixedly connected to the bottom of the blower pipe and the suction pipe. Several sealing components are installed inside the blower pipe, each corresponding to one of the air holes on the blower pipe. A movable seat is slidably attached to the outside of the blower pipe. A lifting component for vertical movement of the movable seat is installed within the switchgear frame, and an air outlet component adapted to the sealing components is installed inside the movable seat.

[0006] Preferably, the sealing component includes a sealing plug adapted to the air hole, and a compression spring fixed to the inner side of the sealing plug is fixed to the inner wall of the blower pipe.

[0007] Preferably, the air outlet component includes two movable tubes, and the movable base has two movable ports. The two movable tubes slide through the two movable ports respectively. The movable base is equipped with a pusher that drives the movable tubes to move. One end of each of the two movable tubes has an air inlet, and the other end is fixed with a flexible hose. An air outlet column is fixed through the flexible hose. A support frame fixed to the outside of the movable base is fixed between the two air outlet columns. A high-pressure air blowing component and a turbulence air blowing component are respectively installed on the outside of the two air outlet columns.

[0008] Preferably, the turbulence blowing component includes a docking end rotatably mounted on the outer end of the air outlet column, the docking end being fixedly connected to a plurality of branch pipes, and the outer ends of the branch pipes being fixedly fitted with inclined pipes.

[0009] Preferably, several of the branch pipes are distributed at equal angles on the outside of the docking end, and both the branch pipes and the inclined pipes are made of rigid polyvinyl chloride.

[0010] Preferably, the high-pressure blowing component includes a thin tube fixed to the outer end of the blowing pipe. The thin tube is L-shaped, and there are two thin tubes distributed on the outside of the blowing pipe.

[0011] Preferably, the pushing component includes a slide bar fixed to the outside of the moving tube, the slide bar slidably fitting with the moving port, and one of the slide bars has a toothed groove. A pushing motor is fixed on the moving base by a motor frame, and a pushing gear that meshes with the toothed groove is fixed to the output end of the pushing motor by a coupling.

[0012] Preferably, the lifting component includes a lifting motor fixed to the bottom of the switch cabinet frame, and a lead screw is fixed to the output end of the lifting motor via a coupling. The lead screw is rotatably connected to the top of the switch cabinet frame, and the lead screw is threadedly inserted into the movable seat.

[0013] Preferably, the sealing plug is made of rubber, and the cross-sectional shape of the sealing plug is convex, with grooves at both ends of the sealing plug.

[0014] Preferably, a filter screen that fits into the air vents is attached to the air suction pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention improves upon existing fan cooling devices by connecting an external blowing and suction device to a designed air duct, and then using an air outlet component to blow and suction air into the switch cabinet, thereby achieving a cooling effect. In particular, a lifting component is used to move the air outlet component up and down along the blowing duct and connect to different air holes, thereby achieving targeted air blowing at different locations and better cooling effect. In this invention, the high-pressure blowing component and the turbulent blowing component serve two blowing methods. The high-pressure blowing component can quickly blow air into a specific area to disperse the accumulated heat source, while the turbulent blowing component can disturb the airflow around the heat source and transfer the heat source within a certain range, thus achieving a good heat source transfer effect.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 6The diagram shows an intelligent heat dissipation type removable high-voltage switchgear, including a switchgear frame 1, a mounting plate 2 fixed inside the switchgear frame 1, heat dissipation fins 3 installed on the mounting plate 2, a blower pipe 4 and a suction pipe 5 fixed on both sides of the switchgear frame 1 respectively, air holes 6 opened on the blower pipe 4 and the suction pipe 5, an air pipe 7 fixedly connected to the bottom of the blower pipe 4 and the suction pipe 5, and a number of sealing parts 8 installed inside the blower pipe 4, the number of sealing parts 8 corresponding to the number of air holes 6 on the blower pipe 4, and a movable seat 9 slidably attached to the outside of the blower pipe 4. A lifting part 10 for moving the movable seat 9 up and down is installed inside the switchgear frame 1, and an air outlet part 11 adapted to the sealing parts 8 is installed inside the movable seat 9. In this design, the air pipe 7 is connected to the external air intake and air blowing equipment, so that the air blowing pipe 4 and the air intake pipe 5 can play the corresponding air blowing and air intake effects. Then, the air hole 6 is used to blow and draw air to transfer and exhaust the internal heat source. The lifting component 10 is used to drive the air outlet component 11 to perform air blowing operations at different locations, which can achieve targeted heat dissipation.

[0020] For further details, please refer to [link / reference]. Figure 5 and Figure 7 The sealing component 8 includes a sealing plug 12 adapted to the air hole 6, and a compression spring 13 fixed to the inner side of the sealing plug 12 and fixed to the inner wall of the blow pipe 4. In this solution, the blower pipe 4 has a large internal air pressure due to its connection with the external blower equipment. With the help of the compression spring 13, the sealing plug 12 can block the air hole 6. With the help of the subsequent air outlet component 11 to resist the sealing plug 12, it can provide targeted blower treatment for a certain area.

[0021] It should also be noted that, in order to improve the sealing effect of the sealing plug 12, the sealing plug 12 is made of rubber material and has a convex cross-sectional shape. In addition, in order to facilitate the pushing and adjustment of the sealing plug 12, grooves 32 are provided at both ends of the sealing plug 12.

[0022] For further details, please refer to [link / reference]. Figure 3 - Figure 7 The air outlet component 11 includes two movable tubes 14. The movable base 9 has two movable ports 15. The two movable tubes 14 slide through the two movable ports 15 respectively. The movable base 9 is equipped with a pusher 16 that drives the movable tubes 14 to move. One end of the two movable tubes 14 is provided with an air inlet 33, and the other end is fixed with a hose 17. An air outlet column 18 is fixed through the hose 17. A support frame 19 is fixed to the outside of the movable base 9 between the two air outlet columns 18. A high-pressure air blowing component 20 and a turbulent air blowing component 21 are respectively installed on the outside of the two air outlet columns 18. It should be noted that the pusher 16 drives the moving tube 14 to move on the moving seat 9, so that the top of the moving tube 14 opens the seal blockage 12, and after entering, it connects with the blower tube 4 through the air inlet 33, so that air enters into the moving tube 14, and the airflow is transmitted to the high-pressure blower 20 and the turbulent blower 21 through the hose 17 and the air outlet column 18.

[0023] For further details, please refer to [link / reference]. Figure 4 - Figure 7 The turbulence blowing component 21 includes a docking end 22 rotatably mounted on the outer end of the air outlet column 18, and a plurality of branch pipes 23 are fixedly connected to the docking end 22, and an inclined pipe 24 is fixed to the outer end of the branch pipe 23. In order to enable the branch pipe 23 to rotate more smoothly, several branch pipes 23 are designed to be distributed at equal angles on the outside of the docking end 22. Both the branch pipe 23 and the inclined pipe 24 are made of high-strength, high-quality, and lightweight rigid polyvinyl chloride material.

[0024] In this scheme, the operating principle of the turbulence blowing component 21 is as follows: First, the moving pipe 14 is extended into the blowing pipe 4 by the pushing component 16. The gas in the blowing pipe 4 rushes into the air outlet column 18 and is discharged outward through the docking end 22 and the branch pipe 23. Due to the inclined state of the inclined pipe 24, combined with the airflow discharge, the branch pipe 23 can drive the docking end 22 to rotate along the air outlet column 18, which plays a rotating blowing role, thereby turbulenting the heat source inside the switch cabinet, preventing the heat source from accumulating, and facilitating the subsequent absorption of the heat source.

[0025] Additionally, see Figure 4 - Figure 7 The high-pressure blowing component 20 includes a thin tube 25 fixed to the outer end of the blowing pipe 4. The thin tube 25 is L-shaped and there are two thin tubes 25, which are distributed on the outside of the blowing pipe 4. In this scheme, the blowing principle of the high-pressure blowing component 20 is as follows: First, the gas is blown into the thin tube 25 through the air outlet column 18. Since the thin tube 25 is thin, when the air pressure is constant, the airflow discharged from the thin tube 25 is strong and can blow to a farther distance. This allows for targeted blowing of air onto a specific heat dissipation fin 3 on the mounting plate 2, dispersing the heat source that is concentrated in the middle or far away, making it easier to remove the heat source later and achieving a better heat dissipation effect.

[0026] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The lifting component 10 includes a lifting motor 30 fixed to the bottom of the switch cabinet frame 1. The output end of the lifting motor 30 is fixed with a lead screw 31 through a coupling. The lead screw 31 is rotatably connected to the top of the switch cabinet frame 1. The lead screw 31 is threadedly connected to the movable seat 9. In this solution, the lifting motor 30 drives the lead screw 31 to rotate, thereby driving the moving seat 9 to lift to a specified height and adjusting the position of the air outlet component 11. In this solution, temperature sensors are designed at equal intervals on the switch cabinet frame 1, which can detect areas with excessively high temperatures in real time, thereby driving the air outlet component 11 to move to the designated area for targeted heat dissipation.

[0027] It should be noted that, in order to prevent debris from entering the air vent 6, a filter screen that fits into the air vent 6 is attached to the air suction pipe 5.

[0028] Example 2: Please refer to Figure 5 and Figure 6 This embodiment further explains Embodiment 1, and the difference lies in that it discloses one specific embodiment of the pusher 16.

[0029] Specifically, the pusher 16 includes a slide bar 26 fixed to the outside of the moving tube 14. The slide bar 26 slides and fits in contact with the moving port 15. One of the slide bars 26 has a toothed groove 27. The moving seat 9 is fixed with a pusher motor 28 by a motor frame. The output end of the pusher motor 28 is fixed with a pusher gear 29 that meshes with the toothed groove 27 by a coupling. The design of the slide bar 26 ensures that the moving tube 14 does not rotate when the moving port 15 moves. The rotation of the push motor 28 drives the push gear 29 to rotate, causing the tooth groove 27 to move accordingly, thereby controlling the extension and retraction of the moving tube 14 in the moving seat 9.
