[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0031] The present invention will be further described below in conjunction with the embodiments.

[0032] Example: Refer to Figures 1 to 7 The present invention provides a technical solution: a power distribution cabinet that is convenient for dividing the internal space, comprising: a power distribution cabinet chassis 1, a voltmeter 23 and an ammeter 24, the voltmeter 23 is lifted and moved on the left and right sides of the power distribution cabinet chassis 1, the ammeter 24 is installed on the inner rear side of the power distribution cabinet chassis 1, the power distribution cabinet chassis 1 is divided into an inner left side, an inner right side, an inner bottom and an inner top, one side of the power distribution cabinet chassis 1 is provided with a take-in and put-out port, and the inner wall of the take-in and put-out port is rotatably connected with a cabinet door 22;

[0033] It is characterized by further comprising:

[0034] The cold air heating mechanism includes a turbine line 2 13 and a turbine line 12 for compressing cold air. The turbine line 2 13 drives the fan blade 19 to rotate through the external cold air, so that the distance between the turbine line 2 13 and the turbine line 12 is shortened and extended cyclically. The turbine line 2 13 and the turbine line 12 both have an outer end and an inner end, and the inner end and the outer end of the turbine line 2 13 and the turbine line 12 are in the same plane. The outer end of the turbine line 12 and the outer end of the turbine line 2 13 provide air through the air intake hole 16 to be compressed into hot air, and the air intake hole 16 is located directly above the outer ends of the turbine line 12 and the turbine line 2 13;

[0035] The one-way inflation mechanism includes a fixed rod 35, a hollow pull tube 45 and a telescopic rod 4. The fixed rod 35 is adjusted in height through the telescopic rod 4. The fixed rod 35 is used to fix multiple ammeters 24. The fixed rod 35 moves to divide the internal space of the distribution cabinet chassis 1. The telescopic rod 4 reciprocates through the hollow pull tube 45 to provide inflation to the interior thereof.

[0036] like Figure 1 , Fig. 9 and Fig.10 As shown, a plurality of concave-convex grooves 3 are provided on the inner rear side of the power distribution cabinet chassis 1, and the plurality of concave-convex grooves 3 are arranged vertically in a nine-square grid, at least one circular bottom plate 34 is slidably connected in the concave-convex grooves 3, a support rod 32 is fixedly installed on one side of the circular bottom plate 34, and the support rod 32 is divided into a head end and an end end, a clamping ring 33 is threadedly connected on the rod body of the support rod 32 near the end, a clamping groove 31 is fixedly installed on the head end, the clamping groove 31 is closed on one side and has an opening on the other side, a clamping plate 30 is clamped on the inner wall of the opening, and the clamping plate 30 is fixedly installed on one side of the voltmeter 23, and the distance between the voltmeter 23 and the inner rear side of the power distribution cabinet chassis 1 is smaller than the distance between the fixed rod 35 and the inner rear side of the power distribution cabinet chassis 1.

[0037] When the outside temperature reaches minus 25 degrees or even lower, and there is wind, the wind blade 19 will be driven first to drive the optical axis 101 and the driving member 17 to rotate, that is, the outside cold air enters the outer ends of the turbine line 12 and the turbine line 2 13 from the air intake hole 16, and then the turbine line 2 13 is fixed, and the turbine line 12 is driven by the driving member 17 to move eccentrically, and the air between the turbine line 12 and the turbine line 2 13 will be continuously compressed to form hot air. The principle can be explained by referring to the working principle of the turbo compressor. Then, if the staff needs to overhaul, they can use the hot air in the distribution cabinet chassis 1 to warm themselves up to avoid severe cold and ensure the safety of the staff. At the same time, no electricity is required, as long as there is wind. Finally, the hot air flows from the inner ends of the turbine line 12 and the turbine line 2 13 to the distribution cabinet chassis 1, dispels the cold air of the voltmeter 23 and the ammeter 24, and avoids deformation, cracking and other problems.

[0038] In order to facilitate the division of the space layout in the power distribution cabinet chassis 1 and to save more time for the staff to repair the power distribution cabinet chassis 1, when it is necessary to adjust the installation position of the voltmeter 23, as shown in FIG. Fig.10 As shown, the support rod 32 can be moved to the ideal position through the path formed by the multiple concave-convex grooves 3, and then the snap ring 33 can be manually rotated, that is, the snap ring 33 is tightly attached to one side of the inner wall of the concave-convex groove 3, and at the same time, the circular bottom plate 34 is tightly attached to the other side of the inner wall of the concave-convex groove 3. The operation is convenient, and then the snap plate 30 on one side of the voltmeter 23 can be inserted into the snap groove 31, and multiple voltmeters 23 can be installed to improve the practicality of the distribution cabinet chassis 1.

[0039] like Figures 3 to 6As shown, the top of the distribution cabinet chassis 1 is connected with an asbestos pipe 10, and the top of the asbestos pipe 10 is connected with a heating shell 11. The upper surface of the heating shell 11 is concave, and the upper surface of the heating shell 11 is fixedly installed on the outer wall of the turbine line 12. The inner wall of the heating shell 11 is in airtight contact with the outer wall of the turbine line 2 13. The top of the heating shell 11 is in airtight contact with a sealing cover 14, and an inclined circular plate 15 is fixedly installed on the top of the sealing cover 14. The air intake hole 16 is opened at the top of the sealing cover 14 and the inclined circular plate 15. The top of the inclined circular plate 15 is inclined, and the air intake hole 16 is at the lowest position of the inclined surface of the inclined circular plate 15. The top of the inclined circular plate 15 A driving member 17 is fixedly installed at the centrifugal position, and the driving member 17 consists of an upper straight rod 170, a transverse rod 171 and a lower straight rod 172. The bottom end of the upper straight rod 170 is fixedly installed on the top of the transverse rod 171, and the bottom of the transverse rod 171 is fixedly installed on the top of the lower straight rod 172. The upper straight rod 170 and the lower straight rod 172 are respectively located on the left and right sides of the transverse rod 171. A limiting circular plate 2 is fixedly installed on the top of the upper straight rod 170, and an optical axis 101 is fixedly installed on the top of the limiting circular plate 2. A plurality of fan blades 18 and fan blade plates 19 are fixedly installed on the rod body of the optical axis 101. The horizontal height of the fan blade plate 19 is higher than the horizontal height of the fan blade 18.

[0040] When the cold wind drives the optical axis 101 to rotate through the wind blade plate 19, the fan blade 18 also rotates accordingly. Figure 6 As shown, the outside air will be pulled to the top of the inclined circular plate 15 by the fan blades 18, and then affected by the inclination of the top of the inclined circular plate 15, the air flow will move to the air intake hole 16 along the inclined outer surface, and then the air will be compressed into hot air through the turbine line 12 and the turbine line 2 13. In order to prevent the hot air from being unable to fully enter the distribution cabinet chassis 1 from the asbestos pipe 10, the subsequent air enters the outer ends of the turbine line 12 and the turbine line 2 13, as shown in the attached Figure 5 As shown, the hot air at the inner ends of turbine line 12 and turbine line 2 13 is pushed into the asbestos tube 10. It is explained that asbestos material can have a good heat insulation effect, so it can prevent the hot air from being absorbed by the external cold air.

[0041] like Figure 3 and Figure 4 As shown, an L-shaped rod 20 is fixedly installed on the top of the distribution cabinet chassis 1, and a supporting ring 21 is fixedly installed on one side of the L-shaped rod 20. The top of the supporting ring 21 contacts the bottom of the limiting circular plate 2, and the rod body of the upper straight rod 170 passes through and is rotatably connected to the inner wall of the supporting ring 21.

[0042] In order to support the position of the optical axis 101 so that the inclined circular plate 15 and the sealing cover 14 can be eccentrically rotated, the L-shaped rod 20, the supporting ring 21 and the limiting circular plate 2 can be used for limiting. At the same time, it also ensures that the optical axis 101 can achieve self-rotation and that the inclined circular plate 15 and the sealing cover 14 are driven by the driving member 17 to perform eccentric rotation.

[0043] like Figure 1 and Figure 2 as well as Figures 7 to 11 As shown, limit grooves 37 are provided on the left and right sides of the inner wall of the distribution cabinet chassis 1, and an I-shaped rod 36 is slidably connected to the inner wall of the limit groove 37. The two I-shaped rods 36 are fixedly installed on the opposite sides of the fixed rod 35, and the telescopic rod 4 is fixedly installed on the inner wall of one of the limit grooves 37. The telescopic rod 4 is hollow inside, and the rod body of the telescopic rod 4 near the bottom end is connected with a vent pipe 40, and the inner wall of the vent pipe 40 is air-tightly slidably connected with a piston 1 41, and the side of the piston 1 41 away from the telescopic rod 4 is connected with a hollow pull tube 45, and a pull rod 42 is fixedly installed on the inner wall of the hollow pull tube 45, and a spring 43 is fixedly installed on the side of the pull rod 42 close to the piston 1 41, and a piston 2 44 is fixedly installed on the other end of the spring 43, and the side of the piston 2 44 close to the spring 43 is in air-tight contact with one side of the piston 1 41.

[0044] When the staff needs to adjust the height of the ammeter 24, the hollow pull tube 45 can be manually moved back and forth, that is, when the hollow pull tube 45 moves toward the telescopic rod 4, the pressure in the ventilation tube 40 is greater than the external pressure, and the piston 2 44 is in airtight contact with one side of the piston 1 41, so that the gas is squeezed into the telescopic rod 4, and the telescopic rod 4 will automatically extend its height. Similarly, when the hollow pull tube 45 moves away from the telescopic rod 4, the pressure in the ventilation tube 40 is less than the external pressure, the piston 2 44 will no longer contact one side of the piston 1 41, and the air in the hollow pull tube 45 will circulate with the external air, so that the hollow pull tube 45 can be opened. The vent pipe 40 and the telescopic rod 4 are in an air circulation state, and the outside air will automatically enter the inner wall of the vent pipe 40 through the hollow pull pipe 45 because the pressure inside the vent pipe 40 is relatively low. Finally, the hollow pull pipe 45 is moved toward the telescopic rod 4, and the spring 43 automatically pulls the piston 2 44 to make airtight contact with one side of the piston 1 41. By analogy, the inner wall of the telescopic rod 4 will be continuously filled with gas and then brought to adjust the height of the telescopic rod 4 and the fixed rod 35.

[0045] If the telescopic rod 4 needs to be shortened, the staff only needs to pull the piston 1 41 out of the inner wall of the vent pipe 40, and then manually adjust the length of the telescopic rod 4, and then insert the piston 1 41 into the inner wall of the vent pipe 40. If it is not the ideal height, the hollow pull tube 45 can be manually moved back and forth.

[0046] To explain, Fig.11As shown, the ammeter 24 will not overlap with the voltmeter 23 during the height adjustment process, thereby reducing the limitations of the space division of the power distribution cabinet chassis 1.

[0047] Operation process:

[0048] When the outside temperature reaches minus 25 degrees or even lower, and there is wind, the cold wind will drive the optical axis 101 through the wind blade plate 19, and the fan blade 18 will also rotate accordingly. Figure 6 As shown in FIG. 1 , the outside air is drawn to the top of the inclined circular plate 15 by the fan blades 18, and then, affected by the inclination of the top of the inclined circular plate 15, the air flow moves into the air intake hole 16 along the inclined outer surface, and enters the outer ends of the turbine line 12 and the turbine line 2 13 through the subsequent air, as shown in FIG. Figure 5 As shown, the hot air at the inner ends of the turbine line 12 and the turbine line 2 13 is pushed into the asbestos tube 10, wherein the turbine line 12 is driven by the driving member 17 to move eccentrically, and the air between the turbine line 12 and the turbine line 2 13 is continuously compressed, thereby forming hot air;

[0049] In order to facilitate the division of the space layout in the power distribution cabinet chassis 1 and to save more time for the staff to repair the power distribution cabinet chassis 1, when it is necessary to adjust the installation position of the voltmeter 23, as shown in FIG. Fig.10 As shown, the support rod 32 can be moved to the desired position through the path formed by the multiple concave-convex grooves 3, and then the clamping ring 33 can be manually rotated, that is, the clamping ring 33 is tightly attached to one side of the inner wall of the concave-convex groove 3, and the circular bottom plate 34 is tightly attached to the other side of the inner wall of the concave-convex groove 3, which is easy to operate, and then the clamping plate 30 on one side of the voltmeter 23 can be inserted into the clamping groove 31;

[0050] When the staff needs to adjust the height of the ammeter 24, they can manually move the hollow pull tube 45 back and forth, that is, when the hollow pull tube 45 moves toward the telescopic rod 4, the telescopic rod 4 will automatically extend its height. If the telescopic rod 4 needs to be shortened, the staff only needs to pull the piston 41 out of the inner wall of the ventilation pipe 40, and then manually adjust the length of the telescopic rod 4, and then insert the piston 41 into the inner wall of the ventilation pipe 40.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
