[0030] Protective clothing, the protective clothing comprising an integrally formed protective suit 1, sleeves 2, gloves 3, a hood 4, trouser legs 5 and protective shoes 6;

[0031] An air extraction system, the air extraction system comprising a sleeve 7 connected to the interior of the protective suit, an air extraction fan 8, a power supply socket 9 and a controller 10, for adjusting the air pressure and temperature inside the protective suit;

[0032] An air guide system, the air guide system includes an air guide seat 11 connected to the protective suit and an air guide cavity 12 embedded in the air guide seat 11, which is used to guide external air flow into the protective suit or to remove heat from the protective suit.

[0033] Specifically, in the embodiment of the present invention, the sleeves 2 are seamlessly connected to both sides of the protective clothing 1, and the ends of the sleeves 2 are integrally formed with the gloves 3, ensuring full protection of the hands. At the top of the protective clothing 1, the hood 4 is tightly connected to it by sewing, providing protection for the wearer's head. At the bottom of the protective clothing 1, the trouser legs 5 are symmetrically distributed and integrally sewn, and the ends of the trouser legs 5 are connected to the protective shoes 6, forming all-round protection from head to foot.

[0034] A sleeve 7 connected to the inside of the protective clothing 1 is installed on the back of the protective clothing 1 through a fixing part. An exhaust fan 8 is installed inside the sleeve 7 to improve the internal environment of the protective clothing 1. The sleeve 7 is also equipped with a power supply seat 9 and a controller 10 to provide power and control to the exhaust fan 8 respectively. The controller 10 can control the start and stop of the exhaust fan 8, thereby realizing active adjustment of the internal environment of the protective clothing. The air guide seat 11 is respectively arranged on the front of the trouser leg 5 and the back of the sleeve 2. The center of the air guide seat 11 is connected to an air guide cavity 12, so that the wind can smoothly enter the interior of the protective clothing to enhance the breathability.

[0035] The back of the protective clothing 1 is bonded with a mounting seat 13, and a groove 14 is provided at the center of the mounting seat 13. The groove 14 is rotatably connected to a connecting rod 15 through a bearing. A reel 16 is fixedly sleeved on the connecting rod 15, and a safety rope 17 is wound around the reel 16. One end of the safety rope 17 passes through the through groove 18 to the outside of the mounting seat 13, and a safety hook 19 is installed to connect the wearer to a fixed point in an emergency, providing additional safety protection for the wearer. One end of the connecting rod 15 also passes through the outside of the mounting seat 13, and a rotating disk 21 is fixedly sleeved, so that the wearer can manually adjust the length of the safety rope 17 to meet different work requirements.

[0036] A transparent plate 22 is bonded to the front opening of the hood 4 to ensure a clear line of sight for the wearer and prevent external splashes from damaging the face. The front of the protective clothing 1 is integrally processed with a zipper 23 and a lock tooth 24 that cooperate with each other, so that the wearer can quickly put on and take off the protective clothing and improve work efficiency. The protective clothing 1 and its various components (sleeves 2, gloves 3, hood 4, trouser legs 5 and protective shoes 6) include an inner layer 25 (made of cotton cloth to provide a comfortable touch), an intermediate layer 26 (made of polytetrafluoroethylene to enhance protective performance) and an outer layer 27 (made of polyurethane to provide excellent wear resistance and waterproof effects), which enhances the protective performance.

[0037] The surface of the exhaust fan 8 is symmetrically bolted with a fixing block 28, and the two ends of the fixing block 28 are bolted to the inner wall of the sleeve 7 to ensure that the exhaust fan 8 is firmly installed in the sleeve 7 and reduce vibration and noise during operation. The back of the protective clothing 1 is also bonded with a protective cloth cover 29 through felt, and a gauze 30 is sewn inside to further enhance the protective effect. A baffle 31 is provided inside the air guide seat 11, and a second magic sticker 32 is symmetrically installed on the baffle 31. The inside of the air guide seat 11 is also symmetrically installed with a second magic sticker 33 used in conjunction with the second magic sticker 32, which is used to adjust the opening size of the air guide cavity 12, thereby controlling the amount of airflow entering. A dustproof net 34 is installed inside the air guide cavity 12 through a fixing member to ensure the cleanliness and smoothness of the airflow. A protective strip 35 is also bonded to the front of the protective clothing 1, and a first magic sticker 36 is sewn on the protective strip 35. The front of the protective clothing 1 is sewn with a first magic sticker 37 used in conjunction with the first magic sticker 36, which is easy to adjust and fix.

[0038] The other end of the connecting rod 15 passes through the inside of the limiting groove 20 and is fixedly sleeved with a limiting block 38. A slot 39 is provided on the surface of the limiting block 38. The inside of the limiting groove 20 is slidably connected with an insertion rod 40 that is inserted into the slot 39. One end of the insertion rod 40 passes through the outside of the mounting seat 13 and is fixedly sleeved with a round head 41 for easy operation. A positioning block 42 is also fixedly sleeved on the surface of the insertion rod 40, and a reset spring 43 used in conjunction with the positioning block 42 is sleeved to ensure the stability and ease of use of the insertion rod 40. A connecting strap 44 is sewn at the connection between the protective clothing 1 and the sleeve 2. The connecting strap 44 is fixedly installed with the mounting seat 13 through a fixing piece, further enhancing the overall stability.

[0039] The present invention forms an integrated protective suit by integrally forming the protective suit 1, sleeves 2, gloves 3, hood 4, trouser legs 5 and protective shoes 6. When worn by a person, the connection and sealing of different parts can be made tighter without any gaps, thereby ensuring the protective performance. By installing a sleeve 7 on the protective suit 1, when the exhaust fan 8 is started, the external wind flow passes through the air guide cavity 12 on the air guide seat 11 and enters the internal chamber of the protective suit. The wearer is in the internal chamber of the protective suit, and the wind flow can take away the stuffiness generated by the staff in the chamber, making the staff more comfortable.

[0040] It can be seen from the above description that compared with the prior art, the beneficial effects brought by the embodiments of the present invention are: the present invention forms an integrated protective suit through its unique integrated design and fine assembly, which ensures the sealing of various parts after wearing, effectively prevents the electrical hazards that may occur during the voltage transformer calibration process, and improves the safety protection performance. At the same time, the sleeve arranged on the back of the equipment is connected to the exhaust fan, which can introduce external wind flow in real time, and smoothly enter the interior of the protective suit through the air guide seat and the air guide cavity, effectively eliminating the stuffiness in the chamber and improving the comfort of the calibration personnel. In addition, the protective suit adopts a multi-layer structure design, with the inner layer of cotton cloth providing a comfortable touch, the middle layer of polytetrafluoroethylene enhancing the protective performance, and the outer layer of polyurethane providing excellent wear resistance and waterproof effects. The baffle and Velcro design inside the air guide seat make the air flow adjustment more flexible, further enhancing the protection effect. The ingenious design of the connecting rod and the limit block ensures the effective winding and fixing of the safety rope, and improves the safety of use. The present invention not only comprehensively guarantees the safety of the test personnel, but also significantly improves the comfort and efficiency of the test work, bringing important technological innovation to the safety test work in the power industry.

[0041] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
