Description

Technical Field

[0001] The invention relates to the technical field of protection and cooling, and in particular to a protection and cooling device for forest fire extinguishing. Background Art

[0002] Forest fire prevention refers to a series of prevention and control measures taken to protect forest resources and prevent the occurrence and spread of forest fires. Forest fires not only cause the death of plants and animals, but also lead to a series of ecological problems such as soil erosion, air pollution and climate change. When a forest fire occurs, it is generally necessary to set up fire isolation belts and clean up flammable materials to reduce the risk of forest fires. When setting up fire isolation belts, the temperature in the fire scene is high, the environment is harsh, and there is a lot of smoke and dust in the air. Therefore, it is very necessary to wear protective equipment, especially protective clothing.

[0003] For example, the patent with the authorization announcement number CN112956762B and the authorization announcement date February 9, 2024, and the name of "A Ventilated Protective Clothing" records that an installation box is fixedly installed in the heat dissipation hood, and a drive motor is fixedly installed in the installation box. The left end of the drive shaft is fixedly installed on the output shaft of the drive motor, and the right end of the drive shaft is rotatably installed in the heat dissipation hood. Two rotating rods are symmetrically rotatably installed in the heat dissipation hood, and a number of fan blades are fixedly installed on the two rotating rods, and the two rotating rods are rotatably connected to the drive shaft; the driving motor of the patent can drive the driving shaft to rotate, and the driving shaft drives the two rotating rods to rotate, and the two rotating rods drive the fan blades to rotate to dissipate heat for the wearer. At the same time, the driving shaft can drive the drying plate to move back and forth to wipe the water vapor on the heat dissipation net, and due to the setting of the top plate, the heat dissipation hood will not be directly against the wearer, ensuring comfortable wearing and good breathable and heat dissipation effects. Another example is the patent with the authorization announcement number CN113331510B and the authorization announcement date June 7, 2024, named "A disposable protective clothing based on semiconductor refrigeration and PCM cold storage and temperature control". The patent includes: a protective clothing shell device, which is a connection structure between the upper and lower garments, and a groove shell component is provided at the connection between the upper and lower garments; a refrigeration and heat exchange device, which is embedded in the groove shell component provided on the protective clothing shell device through a fixing component, and includes a PCM cold storage module for transferring cold and absorbing heat; the fixing component includes a buckle structure and a snap structure for connecting the protective clothing shell device and the refrigeration and heat exchange device; a sealing belt device, which is connected to the groove shell component in the protective clothing shell device, and is used to fix the sealed refrigeration and heat exchange device for internal circulation heat exchange; a feedback control device, which is arranged outside the protective clothing shell device, and is respectively connected to the refrigeration and heat exchange device and the sealing belt device through a circuit, for human-machine exchange control and continuous supply of electric energy. This patent has the advantages of functional integration and portability, good refrigeration and heat exchange effect, and easy mobility.

[0004] Although the above-mentioned protective clothing is provided with mechanisms such as a driving motor to drive fan blades or a refrigeration and heat exchange device to circulate heat inside the protective clothing, the above-mentioned device directly exchanges heat inside the protective clothing only by replacing air to circulate heat inside the protective clothing, and the uninterrupted circulation heat exchange causes energy waste; and when the above-mentioned device circulates heat inside the protective clothing, the air transported into the protective clothing is not filtered, and it is difficult to ensure the cleanliness of the interior of the protective clothing when it is used.

[0043] The protective suit 1 is a one-piece protective suit 1, which can completely wrap the user's body to reduce the risk of exposure. A plurality of temperature sensors are arranged in the protective suit 1, the first cooling pipe 2 is arranged inside the upper garment of the protective suit 1, and the second cooling pipe 3 is arranged inside the lower garment of the protective suit 1;

[0044] The air supply component 4 includes a shell 40, which is arranged in the middle of the rear side of the protective suit 1. An air supply mechanism 41 is arranged inside the shell 40. The air supply mechanism 41 is used to transport air to the first cooling tube 2 and the second cooling tube 3. A filter mechanism 42 is arranged at the upper end of the shell 40. The filter mechanism 42 is used to filter impurities in the air so that the air entering the protective suit 1 is clean. A cooling mechanism 43 is arranged below the filter mechanism 42. The cooling mechanism 43 is between the air supply mechanism 41 and the filter mechanism 42. When the cooling mechanism 43 rotates, it can transport the cooled air into the protective suit 1.

[0045] The air supply mechanism 41 includes a rotating motor 410, a driving gear 411 is provided at the output end of the rotating motor 410, two rotating shafts 412 are symmetrically provided in the housing 40 about the rotating motor 410, a driven gear 413 is provided at one end of the rotating shaft 412 close to the driving gear 411, the driving gear 411 is meshed with the driven gear 413, and a fan blade 414 is provided on the outer side of each rotating shaft 412;

[0046] The cooling mechanism 43 includes two mounting cylinders 431. Two connecting holes are provided at the upper end of the outer shell 40. The upper end of the outer shell 40 is provided with a mounting cylinder 431, and the mounting cylinder 431 is communicated with the outer shell 40 through the connecting holes. A plurality of semiconductor cooling plates 432 are evenly arranged on the side wall of each mounting cylinder 431 along its circumference. A mounting frame 433 is provided on the inner upper side of the mounting cylinder 431. A mounting shaft 434 is rotatably provided in the middle of the mounting frame 433. A plurality of rotating rods 435 are rotatably provided at the lower end of the mounting frame 433. The plurality of rotating rods 435 are evenly arranged along the circumference of the mounting shaft 434, and two adjacent rotating rods 435 are connected by a wind shield 436.

[0047] In another embodiment provided by the present invention, the interior of the housing 40 is a cavity structure, a baffle 400 is arranged in the housing 40, an inclined portion 401 is arranged at the upper end of the baffle 400, and two vertical portions 402 are arranged at the lower end of the inclined portion 401, the baffle 400 divides the cavity structure of the housing 40 into an installation space 403 and an air intake space 404, a gap is provided between the two vertical portions 402, a driving gear 411 and a driven gear 413 are both arranged in the gap, and a rotating motor 410 is arranged in the installation space 403;

[0048] The specific implementation is as follows: the inclined portion 401 and the vertical plate separate the cavity structure of the outer shell 40, and the inclined portion 401 can guide the filtered air, so as to facilitate the transmission of the filtered air to the fan blades 414, so that after the air filtered by the filter mechanism 42 enters the air intake space 404, the fan blades 414 directly discharge the air entering the air intake space 404 quickly, avoiding the air staying in the cavity structure of the outer shell 40 and causing the air temperature to rise. At the same time, the driving gear 411 and the driven gear 413 are between the two vertical plates, which can effectively avoid the temperature rise of the air due to the friction between the gears.

[0049] In another embodiment provided by the present invention, a battery and a controller are also provided in the installation space 403, and the battery, the controller, the rotating motor 410, the semiconductor cooling sheet 432 and the temperature sensor are all electrically connected;

[0050] The specific implementation is as follows: the battery can provide a stable and reliable energy source to the rotating motor 410, the controller, the semiconductor refrigeration sheet 432 and the temperature sensor, so that the rotating motor 410 can rotate continuously and the controller and the temperature sensor can work for a long time, thereby enabling the air supply mechanism 41 and the cooling mechanism 43 to continuously deliver cooled air to the first cooling tube 2 and the second cooling tube 3, and the battery can be quickly replaced to extend the use time of the protective suit 1.

[0051] In another embodiment provided by the present invention, the filtering mechanism 42 includes a mounting shell 420, a plurality of rectangular grooves are arranged at the upper end of the mounting shell 420, a first filter element 421 is slidably arranged at the upper inner side of the mounting shell 420, a second filter element 422 is slidably arranged at the middle inner portion of the mounting shell 420, a third filter element 423 is slidably arranged at the lower inner side of the mounting shell 420, a plurality of limit rods 424 are rotatably arranged at one side of the mounting shell 420, a torsion spring is arranged between the limit rod 424 and the mounting shell 420, a limit block 425 is arranged below the limit rod 424, the limit block 425 is arranged at the outer side of the mounting shell 420, two docking ports are arranged at the lower end of the mounting shell 420, and the mounting shell 420 is connected to the mounting cylinder 431 through the docking ports;

[0052] The specific implementation method is as follows: the rectangular groove facilitates the rotation of the motor 410 to drive the fan blades 414 to suck air to replenish the air. At the same time, the rectangular groove can filter large floating objects in the air, such as leaves, to prevent large floating objects from entering the filter mechanism 42. After the air is initially filtered by the rectangular groove, it enters the installation shell 420. The air entering the installation shell 420 is filtered multiple times by the first filter element 421, the second filter element 422 and the third filter element 423 to ensure that the air enters the protective clothing through the first cooling tube 2 and the second cooling tube 3. 1; after long-term use, a large amount of dust and other impurities will stick to the surface of the first filter element 421, the second filter element 422 and the third filter element 423, which will affect the effect of the first filter element 421, the second filter element 422 and the third filter element 423 in filtering the air. In order to ensure the cleanliness of the air entering the protective suit 1, the first filter element 421, the second filter element 422 and the third filter element 423 need to be replaced after a period of use. When replacing the first filter element 421, the second filter element 422 and the third filter element 423, only At the same time, the two limiting rods 424 at the same horizontal position are rotated so that the two limiting rods 424 release the lock on the first filter element 421, the second filter element 422 or the third filter element 423, thereby facilitating the first filter element 421, the second filter element 422 or the third filter element 423 to be removed from the mounting shell 420 after the unlocking, so as to replace the first filter element 421, the second filter element 422 or the third filter element 423. When replacing the first filter element 421, the second filter element 422 or the third filter element 423, it is also necessary to twist the two limiting rods 424 at the same horizontal position. Two limit rods 424 make way for the first filter element 421, the second filter element 422 or the third filter element 423 to be inserted into the mounting shell 420. After the first filter element 421, the second filter element 422 or the third filter element 423 is replaced, the torsion spring drives the limit rod 424 to rotate in the opposite direction to reset, and the limit rod 424 is limited by the limit block 425 to prevent the torsion spring from driving the limit rod 424 to rotate excessively, making it difficult to lock the first filter element 421, the second filter element 422 or the third filter element 423.

[0053] In another embodiment provided by the present invention, a fan blade 414 is disposed on the outer side of each rotating shaft 412, and the two fan blades 414 are disposed opposite to each other;

[0054] The specific implementation is as follows: the two fan blades 414 are oppositely arranged, that is, the two fan blades 414 rotate in opposite directions but can convey air in the same direction. Specifically, two driven gears 413 are symmetrically meshed on both sides of the driving gear 411. When the rotating motor 410 drives the driving gear 411 to rotate, the driving gear 411 can drive the two driven gears 413 to rotate at the same time, and the two driven gears 413 rotate in opposite directions. In this way, the two driven gears 413 respectively drive the two fan blades 414 to rotate through the two rotating shafts 412, so that the two fan blades 414 arranged oppositely can convey air in the same direction, so that the filtered air can be conveyed to the protective clothing 1 through the first cooling tube 2 and the second cooling tube 3 respectively.

[0055] In another embodiment provided by the present invention, an aluminum profile heat sink 4320 is provided on one side of the semiconductor cooling sheet 432 facing the mounting tube 431;

[0056] The specific implementation is as follows: the semiconductor cooling sheet 432, also known as the thermoelectric cooling sheet, is a heat pump without sliding parts. It is used in some occasions where space is limited, reliability is high, and there is no refrigerant pollution. When direct current passes through a thermocouple made of two different semiconductor materials in series, heat can be absorbed and released at both ends of the thermocouple respectively, thereby achieving the purpose of cooling. An aluminum profile radiator 4320 is provided on one side facing the mounting tube 431, that is, the cooling surface of the semiconductor cooling sheet 432. The air filtered by the first filter element 421, the second filter element 422 and the third filter element 423 enters the mounting tube 431 through the docking port. The temperature sensor continuously detects the temperature inside the protective suit 1 and the human body, so that the controller controls the start and stop of the semiconductor refrigeration plate 432 according to the temperature detected by the temperature sensor. When the semiconductor refrigeration plate 432 is started, the air passing through the semiconductor refrigeration plate 432 can be cooled, so that the air temperature entering the first cooling tube 2 and the second cooling tube 3 is low, thereby allowing the protective suit 1 to cool down the heated protective suit 1 and the human body in the fire scene, and when the filtered air passes through the semiconductor refrigeration plate 432, the aluminum profile radiator 4320 can increase the contact area with the air, so as to quickly cool the air passing through here.

[0057] Furthermore, an aluminum profile heat sink 4320 is also provided on the side of the semiconductor cooling plate 432 facing away from the mounting tube 431, so that the aluminum profile heat sink 4320 can dissipate heat from the hot end of the semiconductor cooling plate 432, thereby reducing the temperature of the hot end of the semiconductor refrigerator, so that the temperature of the cold end of the semiconductor refrigerator decreases accordingly, allowing the cold end of the semiconductor refrigerator to reach a lower temperature.

[0058] In another embodiment provided by the present invention, the cooling mechanism 43 further includes a movable nut 437, which is arranged on the outer side of the mounting shaft 434 in a threaded manner, and a plurality of support rods 438 are evenly arranged on the outer side of the movable nut 437 along its circumference, and a slide groove 4350 is arranged in the middle of each rotating rod 435, and one end of each support rod 438 away from the movable nut 437 is slidably arranged in the slide groove 4350 of the rotating rod 435, and the number of support rods 438 corresponds to the number of rotating rods 435, and a worm gear 4340 is arranged at the lower end of the mounting shaft 434, and an adjusting rod 4341 is rotatably arranged on the baffle 400, and two worms 4342 are arranged on the adjusting rod 4341, and each worm 4342 is meshed with a worm gear 4340, and a rotating wheel 4343 is arranged at one end of the adjusting rod 4341;

[0059] The specific implementation is as follows: since the rotating motor 410 drives the fan blades 414 to rotate and transport air at a high flow rate and the middle part of the air passing through the mounting tube 431 is difficult to contact the cold end of the semiconductor refrigeration plate 432 and the aluminum profile radiator 4320, the cooling range of the air is small, that is, the temperature difference between the outside air and the air transported into the protective suit 1 is small. In order to increase the temperature difference between the air transported into the protective suit 1 and the outside air, the rotating wheel 4343 is rotated to make the rotating wheel 4343 drive the adjusting rod 4341 to rotate, so that the adjusting rod 4341 drives the two worms 4342 to rotate at the same time. In this way, the two worms 4342 can respectively drive the worm gear 4340 meshing with them to rotate, and then the worm gear 4340 drives the mounting shaft 434 to rotate. When the mounting shaft 434 rotates, the moving nut 437 arranged on its outer side by threaded cooperation rises along the mounting shaft 434, so that the moving nut 437 drives the multiple support rods 438 connected thereto to move synchronously, thereby making the multiple support rods 438 away from the moving nut 4 One end of each of the mounting shafts 437 slides in the slide groove 4350 of the rotating rod 435 connected thereto, that is, when the mounting shaft 434 rotates, the moving nut 437 drives the rotating rods 435 to rotate on the mounting frame 433 through the supporting rods 438, so that the rotating rods 435 open and support the wind shield 436 to be tightened, so that the rotating rods 435 drive the wind shield 436 to cover the connecting hole, reduce the gap between the mounting tube 431 and the housing 40, so as to extend the air and the cold end of the semiconductor refrigerator and the aluminum profile heat dissipation. Meanwhile, the rotating rod 435 and the wind shield 436 can also guide the air in the middle of the mounting cylinder 431 to approach the cylinder wall of the mounting cylinder 431, so that the middle of the air in the mounting cylinder 431 fully contacts the aluminum profile radiator 4320 at the cold end of the semiconductor refrigeration plate 432, thereby fully cooling the air and ensuring that the cooled air enters the first cooling tube 2 and the second cooling tube 3 and enters the protective suit 1, so that the cooled air cools the temperature inside the protective suit 1 and the human body temperature.

[0060] In another embodiment provided by the present invention, an adjusting portion 4344 is provided at one end of the adjusting rod 4341, and the adjusting portion 4344 is evenly provided with clamping holes 4345 along its circumference, a mounting block 4346 is provided on the outer side of the housing 40, a clamping rod 4347 is slidably provided inside the mounting block 4346, and an adjusting spring 4348 is provided between the clamping rod 4347 and the mounting block 4346;

[0061] The specific implementation is as follows: the structure of the worm gear 4340 and the worm 4342 can be self-locking, making it difficult for the installation shaft 434 to rotate, so that the installation shaft 434 can lock the position of the support rod 438 and the rotating rod 435 by moving the nut 437, so that the support rod 438 and the rotating rod 435 lock the position of the wind shield 436. At this time, if the rotating wheel 4343 is accidentally touched, the rotating wheel 4343 can still drive the installation shaft 434 to rotate through the adjusting rod 4341, so that the installation shaft 434 can adjust the position of the support rod 438, the rotating rod 435 and the wind shield 436 by moving the nut 437. In order to avoid accidentally touching the rotating wheel 4343, the clamping rod 4347 is squeezed by the adjusting spring 4348, so that the clamping rod 4347 moves outward along the installation block 4346. In this way, the adjusting rod 4341 is driven by the rotating wheel 4343 to rotate and adjust the support rod 4 38. When the position of the rotating rod 435 and the wind shield 436 is adjusted, the rotating wheel 4343 drives the adjusting part 4344 and the adjusting rod 4341 to rotate synchronously, so that the adjusting part 4344 squeezes the adjusting spring 4348 through the clamping rod 4347, so that the clamping rod 4347 moves back and forth in the mounting block 4346 under the action of the clamping hole 4345 of the adjusting part 4344 and the adjusting spring 4348. When the adjusting part 4344 rotates with the adjusting rod 4341 and the rotating wheel 4343, the outer end of the clamping rod 4347 is clamped into the clamping hole 4345 at different positions on the side of the adjusting part 4344. When the rotating wheel 4343 stops rotating, the clamping rod 4347 can lock the adjusting rod 4341 through the clamping hole 4345 of the adjusting part 4344 to avoid accidentally touching the rotating wheel 4343 and causing the position of the support rod 438, the rotating rod 435 and the wind shield 436 to change.

[0062] In another embodiment provided by the present invention, the first cooling tube 2 and the second cooling tube 3 both include an inner layer 20 and an outer layer 21, the inner layer 20 is a hose, the outer layer 21 is arranged outside the inner layer 20, an accommodation space is arranged between the outer layer 21 and the inner layer 20, and the accommodation space is a closed space, and cooling water 22 is arranged in the accommodation space;

[0063] The specific implementation is as follows: the inner layers 20 of the first cooling tube 2 and the second cooling tube 3 are both connected to the air intake space 404 of the outer shell 40, so that the cooled air can enter the protective suit 1 through the two, and the air with reduced temperature can cool the cooling water 22 in the accommodating space, so that the cooling water 22 can continue to cool the inside of the protective suit 1 and the human body after the temperature is reduced, thereby making full use of the cooling air, extending the cooling protection time of the protective suit 1, and improving the utilization rate of energy.

[0064] In another embodiment provided by the present invention, the air outlet of the first cooling pipe 2 is arranged inside the protective suit 1 and at the trouser legs of the protective suit 1, the air outlet of the second cooling pipe 3 is arranged inside the protective suit 1 and at the back of the protective suit 1, and the air outlet of the protective suit 1 is arranged in the middle of the rear side thereof and the air outlet faces the mounting tube 431;

[0065] The specific implementation is as follows: the air outlet of the first cooling pipe 2 is arranged inside the protective suit 1 and at the trouser leg of the protective suit 1, and the air outlet of the second cooling pipe 3 is arranged inside the protective suit 1 and at the back of the protective suit 1 top, so that the discharged cooling air can directly cool down the inside of the protective suit 1 and the human body, making full use of the cooled air to avoid energy waste. At the same time, the air outlet of the protective suit 1 as a whole is arranged in the middle of the rear side of the protective suit 1, that is, at the position of the air supply component 4, and the air outlet of the protective suit 1 is toward the mounting cylinder 431, so that the air with a large ejection velocity can dissipate the heat generated by the hot end of the semiconductor refrigeration plate 432, thereby reducing the temperature of the hot end of the semiconductor refrigerator, so that the temperature of the cold end of the semiconductor refrigerator drops accordingly, so that the cold end of the semiconductor refrigerator reaches a lower temperature.

[0066] Working principle: Check the battery power, replace or charge it if it is out of power. When the battery power is sufficient, the firefighter selects a suitable protective suit 1 according to the body shape and puts it on. After putting it on, turn on the controller. At this time, the temperature sensor can detect the temperature inside the protective suit 1 and the temperature of the human body. When the temperature inside the protective suit 1 or the human body is high, the controller can control the rotating motor 410 to rotate, so that the rotating motor 410 drives the fan blade 414 to rotate and transport air into the protective suit 1 through the first cooling pipe 2 and the second cooling pipe 3 to cool the inside of the protective suit 1 and the human body. Specifically, the temperature sensor detects the temperature of the protective suit 1. When the temperature inside the protective clothing 1 and the temperature of the human body are high, the controller controls the rotating motor 410 to rotate, so that the rotating motor 410 drives the driving gear 411 to rotate, so that the driving gear 411 drives the two driven gears 413 to rotate at the same time, so that the two driven gears 413 respectively drive the two fan blades 414 to rotate through the two rotating shafts 412, and because the rotation directions of the two driven gears 413 are opposite, two fan blades 414 arranged oppositely are provided, so that the two fan blades 414 arranged oppositely can convey air in the same direction, so that the filtered air is conveyed to the protective clothing 1 through the first cooling pipe 2 and the second cooling pipe 3 respectively;

[0067] When the fan blades 414 convey air into the protective suit 1 through the first cooling tube 2 and the second cooling tube 3 respectively, the outside air enters the installation shell 420, so that the filter mechanism 42 filters the air. Specifically, the rectangular groove facilitates the replenishment of air when the rotating motor 410 drives the fan blades 414 to suck air. At the same time, the rectangular groove can filter and filter large floating objects in the air, such as leaves, to prevent large floating objects from entering the filter mechanism 42. After the air is initially filtered by the rectangular groove, it enters the installation shell 420 and passes through the first filter element 421, the second filter element 422 and the third filter element 424. The core 423 filters the air entering the installation shell 420 multiple times to ensure that the air entering the protective suit 1 through the first cooling tube 2 and the second cooling tube 3 is clean; after long-term use, a large amount of dust and other impurities will adhere to the surface of the first filter element 421, the second filter element 422 and the third filter element 423, and these impurities will affect the effect of the first filter element 421, the second filter element 422 and the third filter element 423 in filtering the air. In order to ensure the cleanliness of the air entering the protective suit 1, the first filter element 421, the second filter element 422 and the third filter element 423 need to be filtered after a period of use. When replacing the first filter element 421, the second filter element 422 and the third filter element 423, it is only necessary to rotate the two limit rods 424 at the same horizontal position at the same time, so that the two limit rods 424 release the lock on the first filter element 421, the second filter element 422 or the third filter element 423, so as to facilitate the first filter element 421, the second filter element 422 or the third filter element 423 to be removed from the mounting shell 420 after the unlocking, so as to replace the first filter element 421, the second filter element 422 or the third filter element 423. 23, it is also necessary to twist the two limit rods 424 at the same horizontal position, so that the two limit rods 424 give way so that the first filter element 421, the second filter element 422 or the third filter element 423 can be inserted into the installation shell 420. After the first filter element 421, the second filter element 422 or the third filter element 423 is replaced, the torsion spring drives the limit rod 424 to rotate in the opposite direction and reset, and the limit rod 424 is limited by the limit block 425 to prevent the torsion spring from driving the limit rod 424 to rotate excessively, making it difficult to lock the first filter element 421, the second filter element 422 or the third filter element 423;

[0068] The filtered air will pass through the installation cylinder 431, so that the cooling mechanism 43 cools the air. Specifically, after the air filtered by the first filter element 421, the second filter element 422 and the third filter element 423 enters the installation cylinder 431 through the docking port, the air contacts the aluminum profile radiator 4320 at the cold end of the semiconductor refrigeration plate 432 to cool the air. At the same time, the temperature sensor continuously detects the temperature inside the protective clothing 1 and the human body, so that the controller controls the start and stop of the semiconductor refrigeration plate 432 according to the temperature detected by the temperature sensor. When the semiconductor refrigeration plate 432 is started, it can cool the air passing through the semiconductor refrigeration plate 432, so that the temperature of the air entering the first cooling tube 2 and the second cooling tube 3 is low, thereby The protective clothing 1 cools down the heated protective clothing 1 and the human body in a fire scene, and when the filtered air passes through the semiconductor cooling sheet 432, the aluminum profile radiator 4320 can increase the contact area with the air so as to quickly cool down the air passing therethrough; further, an aluminum profile radiator 4320 is also provided on the side of the semiconductor cooling sheet 432 away from the mounting tube 431, so that the aluminum profile radiator 4320 dissipates heat from the hot end of the semiconductor cooling sheet 432, thereby reducing the temperature of the hot end of the semiconductor refrigerator, so that the temperature of the cold end of the semiconductor refrigerator decreases accordingly, and the cold end of the semiconductor refrigerator reaches a lower temperature; in addition, since the rotating motor 410 drives the fan blades 414 to rotate and transport the air at a high flow rate and The middle part of the air passing through the installation tube 431 is difficult to contact the cold end of the semiconductor refrigeration plate 432 and the aluminum profile radiator 4320, which results in a small cooling range of the air, that is, a small temperature difference between the outside air and the air transported into the protective suit 1. In order to increase the temperature difference between the air transported into the protective suit 1 and the outside air, the rotating wheel 4343 is rotated to make the rotating wheel 4343 drive the adjusting rod 4341 to rotate, so that the adjusting rod 4341 drives the two worms 4342 to rotate at the same time. In this way, the two worms 4342 can respectively drive the worm gear 4340 meshing with them to rotate, and then the worm gear 4340 drives the installation shaft 434 to rotate. When the installation shaft 434 rotates, a movable nut arranged on its outer side by threaded cooperation 437 rises along the installation shaft 434, so that the moving nut 437 drives the multiple supporting rods 438 connected thereto to move synchronously, so that the ends of the multiple supporting rods 438 away from the moving nut 437 slide in the slide grooves 4350 of the rotating rod 435 connected thereto, that is, when the installation shaft 434 rotates, the moving nut 437 drives the multiple rotating rods 435 to rotate on the installation frame 433 through the multiple supporting rods 438, so that the rotating rod 435 opens and supports the wind shield 436 to be tightened, so that the rotating rod 435 drives the wind shield 436 to cover the connecting hole, and reduces the gap from the installation tube 431 to the shell 40, so as to prolong the contact time between the air and the cold end of the semiconductor refrigerator and the aluminum profile radiator 4320.At the same time, the rotating rod 435 and the wind shield 436 can also guide the air in the middle of the installation tube 431 to approach the tube wall of the installation tube 431, so that the middle of the air in the installation tube 431 can fully contact the aluminum profile radiator 4320 at the cold end of the semiconductor refrigeration plate 432, so that the air is fully cooled, ensuring that the cooled air enters the first cooling tube 2 and the second cooling tube 3 and enters the protective suit 1, so that the cooled air cools the temperature in the protective suit 1 and the human body temperature, and the structure of the worm gear 4340 and the worm 4342 can The self-locking function makes it difficult for the installation shaft 434 to rotate, so that the installation shaft 434 can lock the position of the support rod 438 and the rotating rod 435 by moving the nut 437, so that the support rod 438 and the rotating rod 435 can lock the position of the wind shield 436. At this time, if the rotating wheel 4343 is accidentally touched, the rotating wheel 4343 can still drive the installation shaft 434 to rotate through the adjusting rod 4341, resulting in the installation shaft 434 adjusting the position of the support rod 438, the rotating rod 435 and the wind shield 436 by moving the nut 437. In the case of the wheel 4343, the spring 4348 is adjusted to squeeze the clamping rod 4347, so that the clamping rod 4347 moves outward along the mounting block 4346. In this way, when the adjusting rod 4341 is driven by the rotating wheel 4343 to rotate and adjust the positions of the support rod 438, the rotating rod 435 and the wind shield 436, the rotating wheel 4343 drives the adjusting part 4344 and the adjusting rod 4341 to rotate synchronously, so that the adjusting part 4344 squeezes the adjusting spring 4348 through the clamping rod 4347, so that the clamping rod 4347 is in the clamping hole 4344 of the adjusting part 4344. 5 and the adjusting spring 4348 reciprocates in the mounting block 4346. When the adjusting portion 4344 rotates with the adjusting rod 4341 and the rotating wheel 4343, the outer end of the clamping rod 4347 is clamped into the clamping holes 4345 at different positions on the side of the adjusting portion 4344. When the rotating wheel 4343 stops rotating, the clamping rod 4347 can lock the adjusting rod 4341 through the clamping hole 4345 of the adjusting portion 4344 to avoid accidentally touching the rotating wheel 4343 and causing the positions of the supporting rod 438, the rotating rod 435 and the wind shield 436 to change.

[0069] At the same time, the inner layers 20 of the first cooling tube 2 and the second cooling tube 3 are both connected to the air inlet space 404 of the outer shell 40, so that the cooled air can enter the protective suit 1 through the two, and the air with the lowered temperature can cool the cooling water 22 in the accommodating space, so that the cooling water 22 can continue to cool the inside of the protective suit 1 and the human body after the temperature is lowered, thereby making full use of the cooling air and improving the utilization rate of energy; the air outlet of the first cooling tube 2 is arranged inside the protective suit 1 and at the trouser legs of the protective suit 1, and the air outlet of the second cooling tube 3 is arranged inside the protective suit 1 and at the top of the protective suit 1 The back of the protective suit 1 is provided with a cooling air which can directly cool down the inside of the protective suit 1 and the human body, making full use of the cooled air and avoiding energy waste. At the same time, the air outlet of the protective suit 1 is arranged in the middle of the rear side of the protective suit 1, that is, at the position of the air supply component 4. At the same time, the air outlet of the protective suit 1 is directed toward the mounting cylinder 431, so that the air with a large ejection velocity can dissipate the heat generated by the hot end of the semiconductor refrigeration sheet 432, thereby reducing the temperature of the hot end of the semiconductor refrigerator, so that the temperature of the cold end of the semiconductor refrigerator drops accordingly, and the cold end of the semiconductor refrigerator reaches a lower temperature.
