Description

Technical Field

[0001] The invention relates to the technical field of power boxes, in particular to a power box for electric power engineering. Background Art

[0002] A power box is a device used to distribute and control electrical energy, usually including components such as switches, protective devices and measuring instruments to ensure the safe, stable and efficient operation of the power system. A power box, also known as a distribution box or an electric control box, is a device that integrates electrical components such as switches, protective devices and measuring instruments. Its main function is to distribute, control and protect electrical energy to ensure that electrical energy can be safely and stably transmitted to various electrical equipment. In the power system, the power box is an important component and undertakes the key tasks of distributing and controlling electrical energy.

[0003] The power box is a device used to distribute electrical energy. It contains multiple electrical components, such as circuit breakers, fuses, contactors, etc. These electrical components will generate a certain amount of heat in the process of receiving current from the power supply and distributing electrical energy to different load electrical appliances. If the heat accumulates too much, it will cause the temperature of the components to be too high, and may even cause the components to burn out, thus affecting the normal operation of the entire power box.

[0004] In addition, high temperature environment will accelerate the aging of electrical components, shorten their service life and increase the failure rate. Therefore, in order to ensure the normal operation of the power box and extend its service life, effective heat dissipation measures must be taken to dissipate the internal heat in time and keep the components within the appropriate operating temperature range.

[0005] In the prior art, in order to reduce the temperature inside the power box, air holes are generally provided on the power box. Although the air holes have a certain heat dissipation function, the effect is not good. In addition, since the air holes make the power box connected to the outside world for a long time, dust will also enter the box through the air holes. A large amount of dust gathers in the power box, which not only affects the normal heat dissipation of the power box and reduces the insulation performance, but also causes failures and increases safety hazards. Summary of the invention

Two ends of the spring are respectively against the retaining ring and the rotating seat.

[0012] As a further solution of the present invention: a slide groove is provided on the disc and along the diameter direction thereof, the number of the slide grooves is multiple, and the multiple slide grooves are evenly distributed; I-shaped blocks are slidably arranged inside the plurality of slide grooves, and the plurality of I-shaped blocks and the frame are rotationally connected via connecting rods.

[0013] As a further solution of the present invention: an L-shaped rod is fixedly provided on the rotating seat, and the L-shaped rod is rotatably connected to the other end of one of the louvers close to the air inlet through a connecting column; The outer wall of the cabinet is provided with a sealing cover, and the sealing cover covers the driving component inside.

[0014] As a further solution of the present invention: the wind sweeping assembly includes a U-shaped frame fixedly arranged on the inner wall of the cabinet and a plurality of wind guide plates rotatably arranged on the U-shaped frame, and one end of two connected wind guide plates are rotatably connected through a connecting piece; A rotating column is vertically rotatably arranged on the cabinet body, a sleeve is movably sleeved on the outer wall of the rotating column, a ball is rollingly engaged inside the sleeve, a track groove is opened on the outer wall of the rotating column along its length direction, and the ball is also rollingly engaged in the track groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In this solution, the two sealing components are respectively capable of closing the air inlet and the air outlet, thereby preventing dust from entering the cabinet when no heat dissipation is performed.

When the temperature inside the cabinet drops, the driving component stops working, and the two sealing components will be reset, so that the air inlet and the air outlet are restored to a closed state to prevent dust from entering the cabinet.

[0018] In the present application, through the mechanical coordination between the sealing component, the heat dissipation component, the driving component, the wind sweeping component and the transmission structure, it is achieved that when heat dissipation is needed, the cabinet switches from a sealed state to a state connected to the outside world, and continuously blows cold air into the cabinet. At the same time, the cold air blown into the cabinet can be guided up and down, and the cabinet is restored to a sealed state when the temperature drops. This solution not only improves the heat dissipation efficiency, but also avoids the long-term connection between the cabinet and the outside world, which causes dust to enter the cabinet, thereby reducing safety hazards.

The two sealing components can respectively seal the air inlet 101 and the air outlet 102, and the two sealing components are connected by a connecting rod 2; The cabinet 1 is provided with a heat dissipation component, which is located at the air inlet 101. When the heat dissipation component is in operation, the air outside the cabinet 1 can be blown toward the air inlet 101. The cabinet 1 is provided with a driving assembly, and the driving assembly is respectively connected to the heat dissipation assembly and one of the sealing assemblies. When the driving assembly is running, the heat dissipation assembly will be actuated, and one of the sealing assemblies will drive the other sealing assembly to be actuated synchronously through the connecting rod 2, so that the air inlet 101 and the air outlet 102 are in an open state; A wind sweeping component is provided on the cabinet 1 and located at the air inlet 101.

[0037] In this solution, the two sealing components are respectively capable of closing the air inlet 101 and the air outlet 102, thereby preventing dust from entering the cabinet 1 when no heat dissipation is performed. When the temperature inside the cabinet 1 is too high and heat dissipation is required, the driving component is started, and the driving component and the connecting rod 2 cooperate with each other to make the two sealing components move synchronously, so that the air inlet 101 and the air outlet 102 are in an open state, that is, the cabinet 1 is connected to the outside world; at the same time, the heat dissipation component will work under the drive of the driving component, and continuously supply air to the cabinet through the air inlet 101. 1 to blow cold air, thereby taking away the heat in the cabinet 1 and achieving rapid cooling; in addition, the driving component will also drive the sweeping component to operate through the transmission structure, and the running sweeping component will reciprocate up and down for the cold air entering the cabinet 1 through the air inlet 101, thereby enhancing the cooling effect of the cold air on the cabinet 1.

[0041] In this embodiment, since the impeller 8 is fixedly provided on the outer wall of the rotating shaft 7 and the first bevel gear 9 is fixedly provided at one end of the rotating shaft 7, when the first bevel gear 9 rotates, the rotating shaft 7 will drive the impeller 8 to rotate, and the rotating impeller 8 can blow air into the cabinet 1 through the air inlet 101.

[0042] See also Figure 6 , Fig. 9 , Fig.13 The driving assembly includes a rotating rod 10 vertically rotating on the cabinet 1 and a second bevel gear 11 fixedly arranged at one end of the rotating rod 10, and the second bevel gear 11 and the first bevel gear 9 are meshed with each other; A motor 12 is fixedly mounted on the cabinet 1 , and an output end of the motor 12 is fixedly connected to the other end of the rotating rod 10 .

[0043] In this embodiment, since the second bevel gear 11 fixed at one end of the rotating rod 10 and the first bevel gear 9 are meshed with each other, when the rotating rod 10 rotates, the second bevel gear 11 will drive the first bevel gear 9 to rotate; Because the other end of the rotating rod 10 is fixedly connected to the output end of the motor 12 , when the motor 12 is started, the output end of the motor 12 will drive the rotating rod 10 to rotate.

As the rotation speed of the rotating rod 10 increases, the disc 14 will cause the multiple I-shaped blocks 19 to generate centrifugal force, so that the multiple I-shaped blocks 19 will slide in the multiple slide grooves 18 toward the end away from the center of the disc 14. The sliding I-shaped blocks 19 will drive the frame 16 to rotate and move upward through the connecting rod 20; and because the frame 16 and the rotating seat 15 rotate in coordination, the frame 16 will drive the rotating seat 15 to move upward.
