Description

Technical Field

[0001] This invention relates to the field of occupational protective clothing technology, specifically to a special environmental occupational uniform with high temperature resistance. Background Technology

[0002] Work uniforms designed for high-temperature environments are core equipment for ensuring worker safety; their performance directly determines the duration of high-temperature tolerance and operational safety. Existing high-temperature resistant work uniforms suffer from the following key technical defects, limiting user experience and protective effectiveness: Passive heat dissipation regulation and poor adaptability: Traditional uniforms mostly rely on the insulation of the fabric itself (such as flame-retardant cotton) or fixed ventilation holes for heat dissipation, and cannot dynamically adjust the ventilation volume according to the ambient temperature. At low temperatures, the ventilation holes are prone to heat loss, and at high temperatures, the heat dissipation efficiency is insufficient. Some uniforms with fans need to be manually turned on and off, which cannot adapt to temperature changes, making operation cumbersome and easy to distract. Lack of active cooling and limited high temperature tolerance: Passive insulation alone cannot cope with continuous high temperatures. Workers will still feel uncomfortable due to heat accumulation, and may even suffer from heatstroke. A few uniforms with cooling functions have messy and easy-to-fall-off pipe layouts, which affect the flexibility of operation. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7This invention provides a technical solution: a special environmental occupational uniform with high temperature resistance, comprising a uniform 1 and a water tank 31. The uniform 1 is made of multi-layer flame-retardant fabric, including an outer layer of flame-retardant aramid, a middle layer of heat-insulating cotton, and an inner layer of skin-friendly cotton. The uniform 1 has connecting openings 2 on both shoulders or waists. A connecting frame 3, directly opposite the connecting openings 2, is sewn inside the uniform 1. An isolation plate 13 is welded to the lower part of the connecting frame 3. Several sets of rotating rods 4 are rotatably connected between the interior of the isolation plate 13 and the upper interior of the connecting frame 3 via deep groove ball bearings. Control fan blades 5 are keyed to the outer side of the rotating rods 4. The surface of the control fan blades 5 is coated with a flame-retardant coating. After the lower part of the rotating rod 4 penetrates the isolation plate 13, a gear 6 is keyed to it. A rack 7 is meshed on one side of the gear 6. Two sets of lugs 8 are welded to the other side of the rack 7. A guide block 9 is slidably connected to one set of lugs 8 with a clearance fit. The other end of the guide block 9 is welded to the connecting frame 31. The inner wall of frame 3 restricts the sliding direction of rack 7. A first spring 10 is fixedly connected to the connecting frame 3 and the set of lugs 8 by spot welding. The first spring 10 is sleeved on the outside of guide block 9. Under normal conditions, it pulls rack 7 to reset. Another set of lugs 8 is fixedly connected to the inner wall of connecting frame 3 by threaded connection with a matching mounting cylinder 11. The mounting cylinder 11 is fitted with a thermosensitive metal 12 with a clearance fit. When the temperature rises, the thermosensitive metal 12 expands and pushes lug 8 and rack 7 to move, driving gear 6 and rotating rod 4 to rotate, controlling fan blade 5 to open. When the temperature drops, the thermosensitive metal 12 contracts, the first spring 10 pulls rack 7 to reset, controlling fan blade 5 to close, realizing adaptive ventilation adjustment. A flexible silicone tube is fixed between the middle layer and inner layer of uniform 1 fabric by needle and thread. The flexible silicone tube adopts a leaf vein fractal layout to cover the main heat dissipation area of ​​uniform torso, ensuring uniform cooling. Connecting tubes 28 are integrally formed on both sides of the flexible silicone tube, and the connecting tubes 28 penetrate to the outside of uniform 1. The lower part of the connecting frame 3 is connected to the maintenance door 14 by a hinge. Two sets of connecting plates 15 are fixedly connected to one side of the maintenance door 14 by welding. The lower part of the connecting frame 3 is slidably connected with a locking rod 16 that is directly opposite the locking hole of the connecting plate 15. One end of the locking rod 16 is fixedly connected to the pull plate 17 by welding. The pull plate 17 and the connecting frame 3 are fixedly connected by spot welding to the second spring 18. The second spring 18 is sleeved on the outside of the locking rod 16. Under normal conditions, pushing the locking rod 16 into the locking hole of the connecting piece 15 will fix the maintenance door 14. Pulling the pull plate 17 will unlock and open the maintenance door 14. The uniform 1 has an inner cover fabric 19 sewn inside, facing the connecting frame 3. The inner cover fabric 19 prevents hard components such as the connecting frame 3 from directly contacting the human skin, reducing friction and discomfort. The middle of the inner cover fabric 19 is sewn with a fireproof mesh 20 facing the connecting opening 2. The fireproof mesh 20 is made of metal fireproof mesh, which ensures smooth ventilation while blocking sparks and foreign objects from entering the connecting frame 3. A second Velcro 22 is sewn to one side of the inner cover fabric 19. The inside of the uniform 1 is sewn with a first Velcro 21 that matches the second Velcro 22, which is used for covering and opening the inner cover fabric 19. The outer side of the uniform 1 is sewn with an outer cover 23 facing the connecting opening 2. When ventilation is not required, the outer cover 23 can cover the connecting opening 2 to prevent heat loss or the entry of rainwater or foreign objects. A third Velcro 24 is sewn to one side of the outer cover 23. A fourth Velcro 25 that matches the third Velcro 24 is sewn to the outer side of the uniform 1 to achieve the opening and closing of the outer cover 23. Two sets of storage sleeves 26 are sewn together on the outside of the uniform 1. An outer cover 23 is placed inside the storage sleeve 26. When the outer cover 23 is opened and closed, it can be put into the storage sleeve 26 to avoid shaking and interfering with the operation. A ventilation net 27 facing the communication port 2 is sewn together in the middle of the upper storage sleeve 26 to ensure ventilation efficiency. Two sets of connecting bend plates 30 are sewn together on the back of the uniform 1. Connecting plates 38 that match the connecting bend plates 30 are welded to both sides of the water tank 31. The connecting plates 38 are threaded to the inside of the connecting bend plates 30 to initially fix the water tank 31. A threaded cylinder 29 is rotatably connected to the lower part of the connecting pipe 28. Two sets of connecting pipes 32 that match the threaded cylinders 29 are welded to the upper part of the water tank 31. The threaded cylinders 29 and the connecting pipes 32 are threaded together to achieve a sealed connection between the connecting pipe 28 and the water tank 31. A fixed pipe 33 is welded to the lower part of one side of the connecting pipe 32. A water pump 34 is fixed to the lower part of the fixed pipe 33 by flange bolts. The water pump 34 is bolted to the inside of the water tank 31. When started, the coolant in the water tank 31 is pumped into the flexible silicone tube, flows through the whole body and then flows back to the water tank 31 to achieve active liquid cooling. The water tank 31 is fixedly connected to the two sides by welding with connecting rings 37. A waist band 39 is fitted on the outside of one connecting ring 37. A fifth Velcro 40 is sewn to the inside of one end of the waist band 39 by needle and thread. A sixth Velcro 41 that matches the fifth Velcro 40 is sewn to the inside of the middle of the waist band 39 by needle and thread. The waist band 39 is tightened around the waist. After being inserted by the connecting ring 37 on the other side, it is bent so that the fifth Velcro 40 and the sixth Velcro 41 fit together. This distributes the weight of the water tank 31 to the waist and back, reduces the load pressure on the connecting bending plate 30, and prevents the water tank 31 from shaking. Several sets of positioning rings 36 are fixedly connected to the outside of the water tank 31 by welding. The connecting pipe 28 is sleeved inside the positioning rings 36 to restrict the position of the pipe and prevent it from getting tangled during movement. Two sets of fixing rods 35 that cooperate with the connecting pipe 28 are fixed to the back of the uniform 1 by needle and thread. When the water tank 31 is not in use, the threaded cylinder 28 at one end of the connecting pipe 28 can be threadedly connected to the fixing rod 35 to prevent the pipe from sagging and wearing or interfering with the operation.

[0018] Working principle: When using this invention, the operator puts on uniform 1, adjusts the position of the inner cover 19 to ensure that it completely covers the connecting frame 3, and fixes the inner cover 19 with the first Velcro 21 and the second Velcro 22 to prevent the hard components from contacting the skin; the connecting plate 38 of the water tank 31 is threaded to the connecting bend plate 30 on the back of the uniform 1 to initially fix the water tank 31; after wrapping the waistband 39 around the waist, it passes through the connecting ring 37 on the other side of the water tank 31 and is tightened and fixed with the fifth Velcro 40 and the sixth Velcro 41 to distribute the weight of the water tank 31 and reduce the pressure on the connecting bend plate 30; Pass the connecting pipe 28 on the outside of uniform 1 through the positioning ring 36 and align it with the connecting pipe 32 of water tank 31. Rotate the threaded cylinder 29 to make it threadedly seal the connection with the connecting pipe 32, thus completing the pipeline positioning and preventing entanglement. When the ambient temperature rises, the heat-sensitive metal 12 inside the connecting frame 3 expands due to heat, pushing the lug 8 and rack 7 to slide along the guide block 9. The rack 7 drives the gear 6 and rotating rod 4 to rotate, controlling the fan blades 5 to open synchronously, and the connecting port 2 to connect with the outside, realizing ventilation and heat dissipation. The higher the temperature, the greater the expansion of the heat-sensitive metal 12, the greater the opening angle of the fan blades 5, and the stronger the ventilation. When the ambient temperature drops, the heat-sensitive metal 12 contracts, the first spring 10 pulls the rack 7 to reset, and drives the gear 6 to rotate in the opposite direction to the rotating rod 4, controlling the fan blades 5 to close and reduce heat loss. If ventilation is not required, cover the connecting opening 2 with the outer cover 23 and secure it; if ventilation is required, the outer cover 23 can be slipped into the lower storage sleeve 26 and the connecting opening 2 can be opened. When the ambient temperature is too high and ventilation alone cannot meet the cooling requirements, the water pump 34 in the water tank 31 is started. The water pump 34 pumps the coolant in the water tank 31 into the connecting pipe 28 through the fixed pipe 33 and the connecting pipe 32, and then into the flexible silicone tube with a leaf vein pattern. The coolant flows in the flexible silicone tube, absorbs the heat of the uniform 1 and the human body, and finally flows back to the water tank 31 to form a circulating cooling. The leaf vein pattern ensures that the coolant covers the main area of ​​the torso and the cooling is uniform. After leaving the high temperature environment, the water pump 34 is turned off. If it is not used for a long time, rotate the threaded cylinder 29 to disconnect the connection between the connecting pipe 28 and the connecting pipe 32, and fix the connecting pipe 29 to the fixed rod 35 to prevent the pipe from sagging. When the heat-sensitive metal 12 malfunctions, pull down the pull plate 17 to disengage the locking rod 16 from the locking hole of the connecting piece 15, and compress the second spring 18; open the maintenance door 14 to inspect the internal components; after the inspection is completed, close the maintenance door 14, release the pull plate 17, and the second spring 18 pushes the locking rod 16 to reset and lock.
