[0007] A transmission assembly, the transmission assembly is assembled on the switch cabinet body and is used to drive a cleaning assembly and a processing assembly to clean snow;

[0008] Wherein, the cleaning assembly comprises a top plate fixedly mounted on the top of the switch cabinet body, a cavity is formed between the top plate and the switch cabinet body, an exhaust hole is opened on the top of the switch cabinet body, and a gathering pipe connected to the cavity is fixedly mounted on the top of the top plate;

[0010] Preferably, the switch cabinet body and the middle part of the top plate are triangular in shape, and the cavity is connected to the switch cabinet body through the exhaust hole;

[0011] The exhaust holes are distributed at two ends of the top of the switch cabinet body, and the apertures of the exhaust holes gradually decrease from the two ends to the middle, so that the airflow in the switch cabinet body is gathered to the middle through the two ends of the cavity.

[0012] Preferably, the gas inside the exhaust pipe is ejected through the jet hole to contact the top of the top plate, and the aperture of the jet hole is smaller than the inner diameter of the exhaust pipe.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention injects air upward into the switch cabinet body through the operation of the heat dissipation fan. The airflow inside the switch cabinet body carries the heat upward, enters the cavity through the exhaust hole, and flows toward the middle along the two ends of the cavity and gathers in the gathering pipe. The hot air flow contacts the inner wall of the top plate during the flow in the cavity, thereby increasing the temperature of the top plate surface. When the temperature of the top plate increases, snow falls on the top of the top plate, gradually melts and separates from the top of the top plate due to the heat, thereby effectively preventing snow from accumulating on the top of the top plate. The cleaning component is pulled downward by the operation of the transmission component, and the exhaust pipe is driven to move downward along the surface of the top plate during the downward movement of the guide frame. The snow accumulated on the top of the top plate is cleaned by the scraper. The hot air flow ejected from the jet hole cleans the snow on the top of the top plate, and cooperates with the scraper to effectively prevent snow from accumulating on the top of the switch cabinet body, thereby effectively preventing the switch cabinet body from being crushed.

[0022] The present invention drives the resistance block to move down along the slide slot by the transmission component moving downward. During the downward movement of the resistance block, the extrusion plate rotates with the fixed shaft as the central axis under the action of the spring sheet, and the distance between the upper end of the extrusion plate and the switch cabinet body gradually increases. At the same time, the cleaning component moves downward to scrape the accumulated snow into between the extrusion plate and the switch cabinet body, and then drives the resistance block to move up along the slide slot and pushes the extrusion plate to rotate with the fixed shaft as the central axis by the transmission frame moving upward. During the rotation, the snow accumulated between the extrusion plate and the switch cabinet body is squeezed by the protrusion. At the same time, since the fixed shaft is connected with the switch cabinet body through the connecting pipe, the heat inside the switch cabinet body will enter the fixed shaft and the through slot through the connecting pipe, so that the surface temperature of the extrusion plate is relatively high, and the accumulated snow is squeezed by the extrusion plate to melt it. The extrusion plate contacts the snow and the temperature continues to decrease, while the heat in the switch cabinet body continues to enter the through slot for heat exchange. In this way, the heat dissipation effect inside the switch cabinet body can be improved by reciprocating the heat exchange of the heat inside the switch cabinet body through the extrusion plate.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 8 As shown, the present invention provides a switch cabinet for electric power equipment, comprising a switch cabinet body 1, a heat dissipation fan 4 is fixedly installed at the bottom of the switch cabinet body 1, and further comprising;

[0034] A cleaning component 3, which is arranged on the top of the switch cabinet body 1 and is used to clean the snow on the top of the switch cabinet body 1;

[0035] A processing component 2, the processing component 2 is installed on the side of the switch cabinet body 1;

[0036] The transmission component 5 is assembled on the switch cabinet body 1 and is used to drive the cleaning component 3 and the processing component 2 to clean the snow;

[0037] The cleaning assembly 3 includes a top plate 31 fixedly mounted on the top of the switch cabinet body 1, a cavity is formed between the top plate 31 and the switch cabinet body 1, an exhaust hole 32 is opened on the top of the switch cabinet body 1, and a gathering pipe 33 connected to the cavity is fixedly mounted on the top of the top plate 31;

[0038] A guide frame 321 is provided outside the switch cabinet body 1, a fixing frame 322 is fixedly installed at the bottom of the guide frame 321, sliders 312 are movably sleeved at both ends of the guide frame 321, an exhaust pipe 311 is fixedly installed outside the slider 312, the exhaust pipe 311 is connected with the inside of the gathering pipe 33 through the corrugated diverter pipe 34, an air injection hole 313 is opened at the bottom of the exhaust pipe 311, and a scraper 314 in contact with the top plate 31 is fixedly installed outside the exhaust pipe 311;

[0039] The middle of the switch cabinet body 1 and the top plate 31 is triangular in shape, and the cavity is connected to the switch cabinet body 1 through the exhaust hole 32;

[0040] The exhaust holes 32 are distributed at both ends of the top of the switch cabinet body 1, and the aperture of the exhaust holes 32 gradually decreases from both ends to the middle, so that the airflow in the switch cabinet body 1 is gathered to the middle through both ends of the cavity;

[0041] The gas inside the exhaust pipe 311 is ejected through the jet hole 313 and contacts the top of the top plate 31. The aperture of the jet hole 313 is smaller than the inner diameter of the exhaust pipe 311.

[0042] A guide rod 323 is fixedly mounted inside the fixing frame 322 , the slider 312 is sleeved on the outside of the fixing frame 322 , and a tension spring 324 is connected between the slider 312 and the fixing frame 322 .

[0043] Through the triangular design of the switch cabinet body 1 and the top plate 31, the accumulated snow falling on the top plate 31 will move down along the arc, reducing the accumulation of snow. At the same time, the snow falls on the top of the top plate 31, and the heat dissipation fan 4 works to inject air into the switch cabinet body 1. The airflow inside the switch cabinet body 1 carries the heat upward, enters the cavity through the exhaust hole 32, and flows toward the middle along the two ends of the cavity and gathers in the gathering pipe 33. The hot air flow contacts the inner wall of the top plate 31 during the flow in the cavity, thereby increasing the temperature of the surface of the top plate 31. When the temperature of the top plate 31 increases, the snow falls on the top of the top plate 31, and is gradually melted and separated from the top of the top plate 31 by the heat, thereby effectively preventing snow from accumulating on the top of the top plate 31.

[0044] When the snow is heavy and the heat of the top plate 31 cannot melt the snow, the cleaning component 3 is pulled downward by the transmission component 5. During the downward movement of the guide frame 321, the exhaust pipe 311 is driven to move downward along the surface of the top plate 31. The exhaust pipe 311 is guided by the top of the top plate 31, so that the slider 312 drives the exhaust pipe 311 to move toward the outer end of the guide frame 321 and stretches the tension spring 324. At the same time, the guide rod 323 guides it during the movement, thereby improving the stability of the movement of the slider 312 and the exhaust pipe 311. Since the scraper 314 contacts the top of the top plate 31, the scraper 314 can be used to scrape the top plate The snow accumulated on the top of the top plate 31 is cleaned, and the upwardly moving airflow in the switch cabinet body 1 is gathered in the gathering pipe 33, and enters the exhaust pipe 311 through the corrugated diverter pipe 34, and then is ejected through the jet hole 313. Since the aperture of the jet hole 313 is smaller than the inner diameter of the exhaust pipe 311, the flow rate of the airflow ejected from the exhaust pipe 311 is increased, and the hot air flow ejected from the jet hole 313 cleans the snow on the top of the top plate 31, and cooperates with the scraper 314 to effectively prevent snow from accumulating on the top of the switch cabinet body 1, thereby effectively preventing the switch cabinet body 1 from being crushed.

[0045] It is explained here that the transmission component 5 can cooperate with the weather through the system, and automatically start working if the weather monitoring shows heavy snow, which can effectively prevent snow from accumulating on the top of the switch cabinet body 1.

[0046] like Figure 5 and Figure 6 As shown, the transmission assembly 5 includes a motor 51 installed outside the switch cabinet body 1, a transmission rod 53 is installed at the output end of the motor 51, a limit rod 55 is fixed outside the switch cabinet body 1, a transmission frame 54 sliding outside the limit rod 55 is sleeved on the outside of the switch cabinet body 1, and a guide groove 52 for the movement of the transmission rod 53 is opened in the middle of the transmission frame 54;

[0047] The transmission frame 54 is connected to the fixing frame 322 via a connecting rod 56 .

[0048] The program-controlled motor 51 drives the transmission rod 53 to make a circular motion. During the rotation of the transmission rod 53, it slides in the guide groove 52 and drives the transmission frame 54 to make an up and down reciprocating motion. During the downward movement of the transmission frame 54, the cleaning component 3 is driven downward by the connecting rod 56, and the snow is cleaned by the cleaning component 3. When the transmission frame 54 moves upward, it drives the cleaning component 3 to move upward and reset.

[0049] like Figure 2 and Figure 8As shown, the processing assembly 2 includes a processing chamber 21 fixedly mounted on the side of the switch cabinet body 1, a fixed shaft 23 is hinged inside the processing chamber 21, an extrusion plate 26 is fixedly mounted outside the fixed shaft 23, a convex block 25 is arranged on the side of the extrusion plate 26, and a resisting block 20 that resists the extrusion plate 26 is fixedly mounted on both sides of the inner wall of the transmission frame 54, a spring 22 is elastically connected between the processing chamber 21 and the extrusion plate 26, and a slide groove 29 for the spring 22 to slide vertically is provided on the side of the processing chamber 21;

[0050] In the initial state, the abutment block 20 is located at the upper end of the slide slot 29, so that the upper end of the extrusion plate 26 does not contact the top side wall of the processing chamber 21, and the spring sheet 22 is in a stretched state;

[0051] The fixed shaft 23 is a hollow structure, and the fixed shaft 23 is connected to the switch cabinet body 1 through a connecting pipe 28;

[0052] A through slot 27 communicating with the fixed shaft 23 is formed inside the extrusion plate 26 .

[0053] The motor 51 drives the transmission frame 54 to make up and down reciprocating motion, and the transmission frame 54 moves downward to drive the resistance block 20 to move downward along the slide groove 29. During the downward movement of the resistance block 20, the extrusion plate 26 rotates with the fixed shaft 23 as the central axis under the action of the spring piece 22, and the distance between the upper end of the extrusion plate 26 and the switch cabinet body 1 gradually increases. At the same time, the transmission frame 54 moves downward to drive the cleaning component 3 to move downward to scrape the snow between the extrusion plate 26 and the switch cabinet body 1, and then the transmission frame 54 moves upward to drive the resistance block 20 to move upward along the slide groove 29 and push the extrusion plate 26 to rotate with the fixed shaft 23 as the central axis. During the rotation, the snow between the extrusion plate 26 and the switch cabinet body 1 is squeezed by the protrusion 25, and at the same time, the cleaning component 3 is moved downward to scrape the snow between the extrusion plate 26 and the switch cabinet body 1. The fixed shaft 23 is connected to the switch cabinet body 1 through the connecting pipe 28, and the heat inside the switch cabinet body 1 will enter the fixed shaft 23 and the through groove 27 through the connecting pipe 28, so that the surface temperature of the extrusion plate 26 is relatively high, and the accumulated snow is squeezed by the extrusion plate 26 to melt it. At the same time, the rotation of the fixed shaft 23 and the mesh tube 24 can improve the melting effect of the snow, and the snow flows downward along the outer wall of the switch cabinet body 1. The extrusion plate 26 contacts the snow, and the temperature continues to decrease, while the heat in the switch cabinet body 1 continues to enter the through groove 27 for heat exchange. In this way, the heat inside the switch cabinet body 1 is exchanged reciprocatingly through the extrusion plate 26 to improve the heat dissipation effect inside the switch cabinet body 1.

[0054] At the same time, in rainy weather, rainwater moves down along the top plate 31 into the processing chamber 21 and moves down along the extrusion plate 26, and hits the outer wall of the switch cabinet body 1 during the downward movement, which can improve the heat dissipation effect of the switch cabinet body 1.

[0055] The working principle and use process of the present invention:

[0056] The heat dissipation fan 4 works to inject air into the switch cabinet body 1 upward. The airflow inside the switch cabinet body 1 carries the heat upward, enters the cavity through the exhaust hole 32, and flows along the two ends of the cavity to the middle and gathers in the gathering pipe 33. The hot air flow contacts the inner wall of the top plate 31 during the flow in the cavity, thereby increasing the temperature of the surface of the top plate 31. The temperature of the top plate 31 increases, and the snow falls on the top of the top plate 31, and gradually melts and separates from the top of the top plate 31 due to the heat, thereby effectively preventing the snow from accumulating on the top of the top plate 31. When the snow is heavy and the heat of the top plate 31 cannot melt the accumulated snow, the motor 51 is controlled by the program to drive the transmission rod 53 to make a circular motion. During the rotation of the transmission rod 53, it slides in the guide groove 52 and drives the transmission frame 54 to make an up and down reciprocating motion. During the downward movement of the transmission frame 54, the cleaning component 3 is driven downward by the connecting rod 56;

[0057] During the downward movement of the guide frame 321, the exhaust pipe 311 is driven to move downward along the surface of the top plate 31. The exhaust pipe 311 is guided by the top of the top plate 31, so that the slider 312 drives the exhaust pipe 311 to move toward the outer end of the guide frame 321 and stretches the tension spring 324. At the same time, the guide rod 323 guides it during the movement, thereby improving the stability of the movement of the slider 312 and the exhaust pipe 311. Since the scraper 314 is in contact with the top of the top plate 31, the scraper 314 can remove the snow accumulated on the top of the top plate 31. The airflow moving upward in the switch cabinet body 1 is gathered in the gathering pipe 33, and enters the exhaust pipe 311 through the corrugated diverter pipe 34, and then is ejected through the jet hole 313. Since the aperture of the jet hole 313 is smaller than the inner diameter of the exhaust pipe 311, the velocity of the airflow ejected from the exhaust pipe 311 is increased. The hot airflow ejected from the jet hole 313 cleans the snow on the top of the top plate 31, and cooperates with the scraper 314 to effectively prevent snow from accumulating on the top of the switch cabinet body 1.

[0058] The motor 51 drives the transmission frame 54 to make up and down reciprocating motion, and the transmission frame 54 moves downward to drive the resistance block 20 to move downward along the slide groove 29. During the downward movement of the resistance block 20, the extrusion plate 26 rotates with the fixed shaft 23 as the central axis under the action of the spring piece 22, and the distance between the upper end of the extrusion plate 26 and the switch cabinet body 1 gradually increases. At the same time, the transmission frame 54 moves downward to drive the cleaning component 3 to move downward to scrape the snow between the extrusion plate 26 and the switch cabinet body 1, and then the transmission frame 54 moves upward to drive the resistance block 20 to move upward along the slide groove 29 and push the extrusion plate 26 to rotate with the fixed shaft 23 as the central axis. During the rotation, the snow between the extrusion plate 26 and the switch cabinet body 1 is squeezed by the protrusion 25, and at the same time, the cleaning component 3 is moved downward to scrape the snow between the extrusion plate 26 and the switch cabinet body 1. The fixed shaft 23 is connected to the switch cabinet body 1 through the connecting pipe 28, and the heat inside the switch cabinet body 1 will enter the fixed shaft 23 and the through groove 27 through the connecting pipe 28, so that the surface temperature of the extrusion plate 26 is relatively high, and the accumulated snow is squeezed by the extrusion plate 26 to melt it. At the same time, the rotation of the fixed shaft 23 and the mesh tube 24 can improve the melting effect of the snow, and the snow flows downward along the outer wall of the switch cabinet body 1. The extrusion plate 26 contacts the snow, and the temperature continues to decrease, while the heat in the switch cabinet body 1 continues to enter the through groove 27 for heat exchange. In this way, the heat inside the switch cabinet body 1 is exchanged reciprocatingly through the extrusion plate 26 to improve the heat dissipation effect inside the switch cabinet body 1.
