Description

Technical Field

[0001] This invention belongs to the field of tool cabinet technology, specifically referring to an electric tool cabinet. Background Technology

[0002] Power tool cabinets are used in substations, distribution rooms, and power distribution rooms to store high-voltage safety tools such as insulating rods, voltage detectors, grounding wires, insulating gloves, insulating boots, safety helmets, and safety belts. Their insulation performance and integrity directly determine the personal safety of workers and the stability of the power grid operation. Underground distribution rooms are enclosed, high-humidity environments, fundamentally different from above-ground distribution rooms. They generally suffer from consistently high humidity, large diurnal temperature variations, capillary damping from the ground, poor air circulation, and a high susceptibility to condensation. Conventional power tool cabinets suffer from poor sealing performance, inadequate dehumidification design, and the tendency for low-temperature condensation to form on the metal cabinet walls, causing water droplets to fall and corrode the cabinet and power tools.

[0003] Therefore, a power tool cabinet is needed to solve the above problems. Summary of the Invention

[0004] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an electrical tool cabinet. A humidity sensor detects humidity, and a gas supply component outputs pressurized gas. On one hand, a jet structure purges and dehumidifies the interior of the cabinet; on the other hand, the reaction force from the jet holes drives a pneumatically controlled rotating component to rotate the mesh panel and tools. Furthermore, the eddy current damping of the slow-rotation switching component enables slow rotation during dehumidification and free rotation during retrieval, thus adapting to the high-humidity, condensation-prone environment of underground power distribution rooms and protecting electrical safety tools.

[0005] The technical solution adopted by this invention is as follows: This invention proposes an electric tool cabinet, including a chassis, an inner shell fixedly provided on the upper wall of the chassis, the inner shell being semi-circular, an inner end cover provided at the upper end of the inner shell, an outer shell rotatably provided on the upper wall of the chassis around the outer side of the inner shell, the outer shell being an oblique arc shape, a retaining ring provided on the upper end face of the outer shell, a pneumatically controlled rotating assembly rotatably provided on the upper wall of the chassis, the pneumatically controlled rotating assembly being provided with multiple mesh plates, a slow rotation switching assembly being provided on the pneumatically controlled rotating assembly, an air supply assembly being provided on the upper end face of the inner shell, the air supply assembly providing pressurized gas to the pneumatically controlled rotating assembly, and multiple humidity sensors being provided on the inner wall of the inner shell.

[0006] Furthermore, the pneumatically controlled rotating assembly includes a turntable, a support tube, an air guide cavity, and a rotating tube. The turntable is rotatably mounted on the upper wall of the chassis and is located within the inner shell. The support tube is symmetrically arranged on the upper wall of the turntable. The air guide cavity has a disc-shaped cavity structure and is located at the upper end of the support tube and connected to it. The rotating tube is located on the upper wall of the air guide cavity and connected to it. The rotating tube passes through the center of the inner end cover. An air jet hood is provided in the middle of the lower wall of the air guide cavity. Air jet holes are provided at equal intervals along the diameter direction on the outer wall of the support tube, and the jet directions of the air jet holes on the two support tubes are opposite.

[0007] Furthermore, the slow-rotation switching assembly includes a fixed ring, a movable rod, a spring, a magnetic block, an inner copper ring, and an outer copper ring. The fixed ring is located on the lower inner wall of the support tube. The spring is located inside the support tube and fixed to the end face of the fixed ring. The movable rod is slidably located inside the support tube. The magnetic block is arc-shaped and located at the lower end of the movable rod. The upper wall of the chassis is provided with a rotating groove, which is annular and aligned vertically with the rotation trajectory of the end of the support tube. The lower wall of the turntable is symmetrically provided with placement grooves, the shape of which matches the shape of the magnetic block. The inner copper ring is located on the inner side wall of the rotating groove, and the outer copper ring is located on the outer side wall of the rotating groove.

[0008] Furthermore, the air supply assembly includes an air pump, a rotary joint, and a connecting pipe. The air pump is located on the upper wall of the inner end cover, the rotary joint is located at the upper end of the rotary pipe, one end of the connecting pipe is connected to the air pump, and the other end of the connecting pipe is connected to the rotary joint. The connecting pipe is a rigid pipe.

[0009] Furthermore, a one-way valve is provided on the lower part of the side wall of the inner housing.

[0010] Furthermore, the jet shroud is a hemispherical hollow shell.

[0011] Furthermore, the outer side wall of the inner housing is provided with a sealing strip from top to bottom.

[0012] Furthermore, the mesh plate is mounted on the support tube via a protrusion, and the protrusion is provided with a locking screw.

[0013] Furthermore, the upper wall of the chassis is provided with an annular groove around the outer side of the inner shell, and the lower end of the outer shell is rotatably disposed within the annular groove.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Adaptable to the harsh working conditions of high humidity and easy condensation in underground power distribution rooms, the humidity sensor monitors the humidity inside the cabinet in real time, and the air supply component outputs pressurized gas, which is blown through the air hood and air vents to the cabinet space and inner wall of the cabinet, effectively suppressing condensation and preventing the cabinet and power tools from getting damp and corroded, ensuring the insulation performance of tools and the safety of operation. 2. The reaction force of the reverse air jet from the support pipe jet hole drives the pneumatic rotating component to rotate the mesh plate and the stored power tools, making the air flow inside the cabinet more uniform and improving the overall dehumidification effect; the mesh plate position is adjustable to accommodate the placement and storage needs of power tools of different sizes. 3. A slow rotation switching component is set up. During dehumidification, the magnetic block falls into the rotating groove. The inner and outer copper rings cut the magnetic lines of force to generate eddy current damping, so that the tool rotates slowly to ensure sufficient dehumidification. After the air pump stops, the spring drives the magnetic block to reset and release the damping. The inside of the cabinet can rotate freely, which makes it convenient for operators to store and retrieve tools. 4. A sealing strip is installed on the outer side of the inner shell. After the outer shell and the inner shell are closed, a sealed storage space is formed. With the help of a one-way valve, airflow can be discharged, which improves the airtightness and moisture-proof ability of the cabinet. The outer shell can be rotated and opened and closed. The overall sealing structure of the cabinet is excellent, which reduces the intrusion of external humid air into the cabinet. Attached Figure Description

An air supply assembly 9 is mounted on the upper end face of the inner shell 2, which provides pressurized gas to the pneumatically controlled rotating assembly 6. Multiple humidity sensors 10 are mounted on the inner wall of the inner shell 2.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the pneumatically controlled rotating assembly 6 includes a turntable 11, a support tube 12, an air guide cavity 13, and a rotating tube 14. The turntable 11 is rotatably mounted on the upper wall of the chassis 1 and is located inside the inner shell 2. The support tube 12 is symmetrically arranged on the upper wall of the turntable 11. The air guide cavity 13 is a disc-shaped cavity structure. The air guide cavity 13 is located at the upper end of the support tube 12 and is connected to the support tube 12. The rotating tube 14 is located on the upper wall of the air guide cavity 13 and is connected to the air guide cavity 13. The rotating tube 14 passes through the center of the inner end cover 3. The lower wall of the air guide cavity 13 is provided with a jet hood 15. The outer wall of the support tube 12 is provided with jet holes 16 at equal intervals along its diameter direction. The jet holes 16 on the two support tubes 12 have opposite jet directions. The jet hood 15 is a hemispherical hollow shell. After the gas is ejected from the jet hood 15, it is evenly distributed in the space enclosed by the inner shell 2 and the outer shell 4.

[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, the slow rotation switching assembly 8 includes a fixed ring 17, a movable rod 18, a spring 19, a magnetic block 20, an inner copper ring 21, and an outer copper ring 22. The fixed ring 17 is located on the lower inner wall of the support tube 12. The spring 19 is located inside the support tube 12 and fixed to the end face of the fixed ring 17. The movable rod 18 is slidably located inside the support tube 12. The magnetic block 20 is arc-shaped and located at the lower end of the movable rod 18. The upper wall of the chassis 1 is provided with a rotating groove 32. The rotating groove 32 is annular and aligned vertically with the rotation trajectory of the end of the support tube 12. The lower wall of the turntable 11 is symmetrically provided with placement grooves 23. The shape of the placement grooves 23 is adapted to the shape of the magnetic block 20. The inner copper ring 21 is located on the inner side wall of the rotating groove 32, and the outer copper ring 22 is located on the outer side wall of the rotating groove 32.

[0023] like Figure 1 As shown, the air supply assembly 9 includes an air pump 24, a rotary joint 25, and a connecting pipe 26. The air pump 24 is located on the upper wall of the inner end cover 3, the rotary joint 25 is located at the upper end of the rotary pipe 14, one end of the connecting pipe 26 is connected to the air pump 24, and the other end of the connecting pipe 26 is connected to the rotary joint 25.

[0024] like Figure 1 and Figure 2 As shown, a one-way valve 27 is provided on the lower part of the side wall of the inner housing 2.

[0025] like Figure 1 , Figure 2 and Figure 7As shown, the outer side wall of the inner shell 2 is provided with a sealing strip 28 from top to bottom to close the outer shell 4. When the outer shell 4 and the inner shell 2 form a closed space, the sealing strip 28 plays a sealing role between the outer shell 4 and the inner shell 2.

[0026] like Figure 1 and Figure 3 As shown, the mesh plate 7 is mounted on the support tube 12 via a protrusion 29. The protrusion 29 is provided with a locking screw 30, which can adjust the position of the mesh plate 7 on the support tube 12, thereby adjusting the distance between the two mesh plates 7.

[0027] like Figure 1 , Figure 2 and Figure 7 As shown, the upper wall of the chassis 1 is provided with an annular groove 31 around the outer side of the inner shell 2, and the lower end of the outer shell 4 is rotatably disposed in the annular groove 31.

[0028] In practical use, loosen the locking screw 30, adjust the position of the mesh plate 7 on the support tube 12 as needed to accommodate the storage of power tools, then place the power tools on the mesh plate 7, and then rotate the outer shell 4. The outer shell 4 will block the opening side of the inner shell 2. When the humidity inside the cabinet exceeds the preset value, the humidity sensor 10 will send a signal to the external controller. The controller will control the air pump 24 to turn on, and the gas will enter the air guide cavity 13 through the connecting tube 26, the rotary joint 25, and the rotary tube 14. Part of the gas in the air guide cavity 13... The gas is injected into the space formed by the inner shell 2 and the outer shell 4 through the jet hood 15. The gas blows from top to bottom and is discharged through the one-way valve 27. At the same time, the gas in the air guide cavity 13 enters the support tube 12 and then the gas is ejected from the jet hole 16. Since the jet holes 16 on the two support tubes 12 spray in opposite directions, the support tube 12 is driven to rotate. The support tube 12 drives the mesh plate 7 and the power tool to rotate. At the same time, the ejected gas blows air onto the inner walls of the inner shell 2 and the outer shell 4, so that the inner walls of the inner shell 2 and the outer shell 4 are dried. After the gas enters the support tube 12, it pushes the movable rod 18 to move downward. The movable rod 18 pushes the magnetic block 20 downward. The magnetic block 20 enters the rotating groove 32 and is located between the inner copper ring 21 and the outer copper ring 22. When the magnetic block 20 rotates along the rotating groove 32, the inner copper ring 21 and the outer copper ring 22 cut the magnetic field lines. The inner copper ring 21 and the outer copper ring 22 generate eddy currents, thereby generating resistance to the rotation of the magnetic block 20, and the rotation speed of the magnetic block 20 slows down. When the humidity inside the inner shell 2 and the outer shell 4 meets the requirements, the control air pump 24 stops, the air pressure in the support tube 12 disappears, the spring 19 drives the movable rod 18 to move upward, the movable rod 18 drives the magnetic block 20 to move upward, the magnetic block 20 is pulled out from between the inner copper ring 21 and the outer copper ring 22 and enters the placement slot 23. When the support tube 12, the turntable 11 and the air guide cavity 13 are rotated, eddy current damping is no longer generated between the magnetic block 20, the inner copper ring 21 and the outer copper ring 22, and the support tube 12 and the mesh plate 7 can be rotated freely, making it convenient to access power tools.

[0029] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
