Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and more specifically to wearable equipment for personal protection of firefighters. Background Art

[0002] Equipment for personal protection of firefighters is an important piece of equipment to ensure the safety of firefighters during dangerous operations such as fire fighting and rescue. The design and manufacture of these equipment need to meet strict safety standards to ensure their reliability and effectiveness.

[0003] Equipment for personal protection of firefighters includes: basic protection equipment, auxiliary function equipment, special environment strengthening equipment and other key equipment. Among them, the basic protection equipment includes fire helmets, fire-fighting protective clothing, fire-fighting gloves and protective boots.

[0004] Among the basic protection equipment, existing fire helmets are made of hard materials and are equipped with protective masks to protect the head from falling objects, high-temperature radiation and lateral extrusion.

[0005] Existing fire helmets in the prior art are composed of a helmet body, a mask and a fixing strap. During a fire, firefighters wear the fire helmets on their heads to protect the heads of firefighters and prevent external debris from floating into the eyes of firefighters at the same time.

[0006] The prior art protects firefighters through the helmet body, the mask and the fixing strap, but there are still the following deficiencies:

[0007] 1. In the prior art, when firefighters wear helmets to carry out rescue operations in a fire scene, due to the large amount of smoke in the fire scene, and there are more dust and burning debris floating in the air, dust will adhere to the surface of the mask. The existing cleaning method is generally to wipe the dust on the surface of the mask with a brush. However, when the brush wipes the surface of the mask, the brush will block the line of sight of firefighters, and at the same time, the brush will also be contaminated with dust when it is outside. When cleaning the mask, more and more dust will accumulate on the surface of the mask, seriously affecting the rescue operations of firefighters.

[0008] 2. In the prior art, the camera on the surface of the fire helmet is a fixed structure and is wirelessly connected to firefighters outside the fire scene, so that the firefighters outside can also see the situation inside the fire scene, thereby commanding the firefighters inside the fire scene. When the camera takes pictures, it can only take pictures according to the position corresponding to the head of the firefighter, which greatly limits the shooting angle and has low practicability.

[0009] Therefore, we propose a wearable device for personal protection of firefighters to solve the problems in the above background. Summary of the Invention

[0010] The object of the present invention is to provide a wearable device for personal protection of firefighters, so as to solve the problems of inconvenient cleaning of dust on the surface of the face mask and the limitation of the shooting angle of the camera proposed in the above background technology.

[0011] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0012] A wearable device for personal protection of firefighters includes a helmet body. One side of the helmet body is fixedly connected with a face mask for protecting the face. The bottom of the helmet body is fixedly installed with a fixing band that can adapt to the size of the firefighter's head. One side of the helmet body is fixedly installed with a storage battery that drives all electrical components in the device. The outer side wall of the face mask is fixedly connected with a blowing pipe for cleaning the dust on the surface of the face mask. A plurality of blowing holes for cleaning the dust on the surface of the face mask are formed on the surface of the blowing pipe. The connection part between the face mask and the helmet body is fixedly connected with a dust suction block for adsorbing dust. A plurality of dust suction holes for facilitating the adsorption of dust are formed on the surface of the dust suction block. A cleaning mechanism for driving the blowing pipe and the dust suction block to work is installed inside the helmet body. A rotatable toothed ring is rotatably connected to the surface of the helmet body. A camera that rotates synchronously with the toothed ring is fixedly installed on the surface of the toothed ring. A transmission mechanism for driving the toothed ring to rotate is installed at one end of the toothed ring.

[0013] A plurality of springs for buffering the head of the firefighter are fixedly connected to the inner wall of the helmet body. One end of the plurality of springs is fixedly connected with an arc-shaped plate. A rubber soft pad for protecting the head of the firefighter is fixedly connected to the surface of the arc-shaped plate.

[0014] The cleaning mechanism includes a micro fan fixedly connected to both sides of the helmet body. The micro fan is connected to one end of the blowing pipe through a trachea. A micro air extractor for extracting smoke and dust is fixedly connected to the top of the helmet body. The micro air extractor is connected to one end of the dust suction block through a trachea.

[0015] A collection box for collecting dust is slidably connected to the surface of the helmet body connected to the micro air extractor. A plurality of filter holes for filtering dust are formed on the surface of the collection box.

[0016] The cleaning mechanism further includes a smoke filter fixedly connected to one side of the micro fan and the micro air extractor.

[0017] The transmission mechanism includes a micro motor fixedly connected to one side of the helmet body. The output shaft of the micro motor is fixedly connected with a gear, and the gear meshes with the surface of the toothed ring to drive the toothed ring to rotate.

[0018] An illuminating lamp for assisting the clarity of the camera is fixedly connected above the camera.

[0019] Radio coils for continuously powering the camera are fixedly connected to both sides of the illuminating lamp and the camera in contact with the helmet body.

[0020] An airbag for emergently protecting a firefighter's head is fixedly connected inside the helmet body. An air generator for inflating the airbag is fixedly connected to the air inlet end of the airbag. A pressure sensor for switching the air generator is fixedly connected to the surface of the arc-shaped plate.

[0021] The airbag is located below the rubber cushion and on the inner side wall of the helmet body.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0023] In the present invention, the helmet body is put on the firefighter's head and fixedly connected to the firefighter's head through a fixing strap. The face mask protects the firefighter's face. When the firefighter enters the fire scene, a micro fan is started, so that the micro fan sends air to the air blowing pipe, and the air blowing pipe drives a plurality of air blowing holes to blow air on the surface of the face mask to disperse the dust on the surface of the face mask. Through the air extraction of the micro air extractor, negative pressure is generated inside the dust suction block, and the dust suction block drives a plurality of dust suction holes to adsorb the dispersed dust. The surface of the face mask is cleaned by wind power, which will not block the sight of the firefighters and will not affect the actions of the firefighters. Through the smoke filter on one side of the micro fan and the micro air extractor, the smoke is filtered to prevent the smoke from being adsorbed on the surface of the face mask.

[0024] When the micro motor drives the gear to rotate, the gear drives the toothed ring to rotate, so that the toothed ring drives the lighting lamp and the camera to rotate along the surface of the helmet body. While the lighting lamp and the camera rotate along the surface of the helmet body, the lighting lamp and the camera are powered through the radio coil, and the angle of the camera is adjusted to ensure that the external firefighters can also see the situation inside the fire scene clearly. The lighting lamp provides auxiliary lighting for the shooting of the camera and can also provide lighting for the firefighters.

[0025] A plurality of springs drive the arc-shaped plate to buffer when a heavy object reaches the surface of the helmet body, so that the arc-shaped plate drives a plurality of springs, and the helmet body bounces off the heavy object. The rubber cushion makes the firefighter's head more comfortable when contacting the arc-shaped plate. When a heavy object hits the surface of the helmet body, when the pressure of the heavy object reaches the triggering range of the pressure sensor, the pressure sensor starts the air generator, so that the air generator inflates the airbag, and the airbag quickly inflates to protect the firefighter's head. The inflation intensity of the airbag will not cause harm to the firefighter's head, which is convenient for protecting the firefighter's head. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] The following describes the detailed implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed implementation manners.

[0036] Please refer to Figure 1-8 , the present invention provides a technical solution:

[0037] As Figure 1 and Figure 2As shown, the wearable device for personal protection of firefighters includes a helmet body 1. One side of the helmet body 1 is fixedly connected with a face mask 2 for protecting the face. The bottom of the helmet body 1 is fixedly installed with a fixing strap 3 that can adapt to the size of the firefighter's head. One side of the helmet body 1 is fixedly installed with a storage battery 4 that drives all the electrical components in the device. The outer side wall of the face mask 2 is fixedly connected with a blowing pipe 5 for cleaning the dust on the surface of the face mask 2. A plurality of air blowing holes 6 for cleaning the dust on the surface of the face mask 2 are formed on the surface of the blowing pipe 5. A dust suction block 7 for adsorbing dust is fixedly connected at the connection between the face mask 2 and the helmet body 1. A plurality of dust suction holes 8 for facilitating dust adsorption are formed on the surface of the dust suction block 7. A cleaning mechanism for driving the blowing pipe 5 and the dust suction block 7 to work is installed inside the helmet body 1. A rotatable toothed ring 9 is rotatably connected to the surface of the helmet body 1. A camera 10 that rotates synchronously with the toothed ring 9 is fixedly installed on the surface of the toothed ring 9. A transmission mechanism for driving the toothed ring 9 to rotate is installed at one end of the toothed ring 9.

[0038] As Figure 1 and Figure 2 shown, put the helmet body 1 on the firefighter's head, and fix the helmet body 1 to the firefighter's head through the fixing strap 3. The face mask 2 protects the firefighter's face. When the firefighter enters the fire scene, the cleaning mechanism makes the blowing pipe 5 drive a plurality of air blowing holes 6 to blow air on the surface of the face mask 2, blowing away the dust on the surface of the face mask 2. Then, the cleaning mechanism makes the dust suction block 7 drive a plurality of dust suction holes 8 to adsorb the blown dust. Cleaning the surface of the face mask 2 by wind will not block the line of sight of the firefighter and will not affect the actions of the firefighter. Then, the transmission mechanism drives the toothed ring 9 to rotate along the surface of the helmet body 1, making the toothed ring 9 drive the camera 10 to rotate and adjust the angle, so that external firefighters can also see the situation inside the fire scene.

[0039] The storage battery 4 is a prior art, mainly used to drive the electrical components in the device. The camera 10 is wirelessly controlled and is a prior art, so it will not be elaborated here.

[0040] Further, as Figure 3 and Figure 6 shown, a plurality of springs 11 for buffering the firefighter's head are fixedly connected to the inner wall of the helmet body 1. One end of the plurality of springs 11 is fixedly connected with an arc-shaped plate 12. A rubber soft pad 13 for protecting the firefighter's head is fixedly connected to the surface of the arc-shaped plate 12.

[0041] The plurality of springs 11 drive the arc-shaped plate 12 to buffer when a heavy object reaches the surface of the helmet body 1, making the arc-shaped plate 12 drive the plurality of springs 11, and the helmet body 1 bounces off the heavy object. The rubber soft pad 13 makes the firefighter's head more comfortable when contacting the arc-shaped plate 12.

[0042] Further, as Figure 1 、 Figure 2 、Figure 3 , Figure 7 and Figure 8 As shown in Figure 3 , Figure 7 and Figure 8 , the cleaning mechanism includes a micro fan 15 fixedly connected to both sides of the helmet body 1. One end of the micro fan 15 is connected to one end of the air blowing pipe 5 through a trachea. A micro air extractor 16 for extracting smoke and dust is fixedly connected to the top of the helmet body 1. One end of the micro air extractor 16 is connected to one end of the dust suction block 7 through a trachea.

[0043] A collection box 18 for collecting dust is slidably connected to the surface of the helmet body 1 where it is connected to the micro air extractor 16. A plurality of filter holes 19 for filtering dust are formed on the surface of the collection box 18.

[0044] The cleaning mechanism further includes a smoke filter 17 fixedly connected to one side of the micro fan 15 and the micro air extractor 16.

[0045] Start the micro fan 15 to make the micro fan 15 send air into the air blowing pipe 5, and then extract air through the micro air extractor 16, so that a negative pressure is generated inside the dust suction block 7 to complete the dust suction work. The smoke is filtered by the smoke filter 17 on one side of the micro fan 15 and the micro air extractor 16 to prevent the smoke from being adsorbed onto the surface of the face mask 2. When the micro air extractor 16 works, the dust is adsorbed into the collection box 18 through the dust suction block 7. The dust is filtered and intercepted by the filter holes 19 on the surface of the collection box 18, so that all the dust reaches the collection box 18. During cleaning, just slide out the collection box 18.

[0046] Both the micro fan 15 and the micro air extractor 16 are driven by a storage battery 4.

[0047] Furthermore, as shown in Figure 1 , Figure 3 and Figure 4 the transmission mechanism includes a micro motor 20 fixedly connected to one side of the helmet body 1. The output shaft of the micro motor 20 is fixedly connected with a gear 21, and the gear 21 meshes with the surface of the tooth ring 9 to drive the tooth ring 9 to rotate.

[0048] A lighting lamp 22 for assisting the clarity of the camera 10 is fixedly connected above the camera 10.

[0049] Radio coils 23 for facilitating continuous power supply to the camera 10 are fixedly connected to both sides of the lighting lamp 22 and the camera 10 in contact with the helmet body 1.

[0050] When the micro motor 20 drives the gear 21 to rotate, the gear 21 drives the toothed ring 9 to rotate, causing the toothed ring 9 to drive the lighting lamp 22 and the camera 10 to rotate along the surface of the helmet body 1. While the lighting lamp 22 and the camera 10 are rotating along the surface of the helmet body 1, the lighting lamp 22 and the camera 10 are powered through the radio coil 23, and the angle of the camera 10 is adjusted to ensure that external firefighters can also see the situation inside the fire field. The lighting lamp 22 provides auxiliary lighting for the shooting of the camera 10 and can also provide lighting for the firefighters.

[0051] Further, as Figure 3 and Figure 6 shown, an airbag 24 for emergently protecting the head of the firefighter is fixedly connected inside the helmet body 1. An air inlet end of the airbag 24 is fixedly connected with a gas generator 25 for inflating the airbag 24, and a pressure sensor 26 for switching the gas generator 25 is fixedly connected to the surface of the arc-shaped plate 12.

[0052] The airbag 24 is located below the rubber soft pad 13 and on the inner side wall of the helmet body 1.

[0053] When a heavy object hits the surface of the helmet body 1, when the pressure of the heavy object reaches the triggering range of the pressure sensor 26, the pressure sensor 26 activates the gas generator 25, causing the gas generator 25 to inflate the airbag 24, so that the airbag 24 quickly inflates to protect the head of the firefighter, and the inflation intensity of the airbag 24 will not cause harm to the head of the firefighter.

[0054] All the electronic components of the above device need to be selected according to the usage environment and are all existing technologies, so they will not be elaborated here.

[0055] The working principle of this wearable device for personal protection of firefighters is as follows:

[0056] By putting the helmet body 1 on the head of the firefighter and fixedly connecting the helmet body 1 to the head of the firefighter through the fixing band 3, the face mask 2 protects the face of the firefighter. When the firefighter enters the fire field, the micro fan 15 is started, so that the micro fan 15 sends air into the air blowing pipe 5, causing the air blowing pipe 5 to drive a plurality of air blowing holes 6 to blow air on the surface of the face mask 2 to disperse the dust on the surface of the face mask 2. Through the micro air extractor 16 for air extraction, negative pressure is generated inside the dust suction block 7, causing the dust suction block 7 to drive a plurality of dust suction holes 8 to adsorb the dispersed dust. The surface of the face mask 2 is cleaned by wind, which will not block the sight of the firefighters and will not affect the actions of the firefighters. Through the smoke filter 17 on one side of the micro fan 15 and the micro air extractor 16, the smoke is filtered to prevent the smoke from being adsorbed onto the surface of the face mask 2.

[0057] When the micro-motor 20 drives the gear 21 to rotate, the gear 21 drives the toothed ring 9 to rotate, causing the toothed ring 9 to drive the lighting lamp 22 and the camera 10 to rotate along the surface of the helmet body 1. While the lighting lamp 22 and the camera 10 are rotating along the surface of the helmet body 1, the lighting lamp 22 and the camera 10 are powered through the radio coil 23, and the angle of the camera 10 is adjusted to ensure that external firefighters can also see the situation inside the fire field. The lighting lamp 22 provides auxiliary lighting for the shooting of the camera 10 and can also provide lighting for the firefighters.

[0058] When the heavy object reaches the surface of the helmet body 1, multiple springs 11 drive the arc-shaped plate 12 to buffer it, causing the arc-shaped plate 12 to drive multiple springs 11, and the helmet body 1 to bounce the heavy object away. The rubber soft pad 13 makes it more comfortable for the firefighter's head to contact the arc-shaped plate 12. When a heavy object hits the surface of the helmet body 1, when the pressure of the heavy object reaches the triggering range of the pressure sensor 26, the pressure sensor 26 activates the gas generator 25, causing the gas generator 25 to inflate the airbag 24, so that the airbag 24 quickly inflates to protect the firefighter's head. The inflation intensity of the airbag 24 will not cause harm to the firefighter's head, which is convenient for protecting the firefighter's head.

[0059] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
