Description

Technical Field

[0001] This invention patent belongs to the field of safety protection equipment technology, and relates to safety helmets, especially a safety helmet for drowning rescue. Background Technology

[0002] Safety helmets are protective equipment used to prevent head injuries from impacts. However, fire helmets, construction safety helmets, mining safety helmets, household personal protective helmets, and outdoor sports helmets do not have rescue or escape guidance functions. Their main function is to prevent head injuries.

[0003] Recent practices in natural disaster prevention and man-made accident safety precautions have shown that if on-site personnel receive effective escape guidance during emergencies, and if external professional rescue personnel can quickly obtain information on the physiological condition and location of trapped personnel, casualties can be greatly reduced. Construction site conditions are complex; in addition to mechanical injuries caused by sharp objects, safety helmets, traditionally designed for personnel safety, become ineffective if workers fall into water. Therefore, to ensure the universality of modern safety helmets, it is necessary to incorporate water rescue devices to improve their safety performance and protective capabilities.

[0004] Invention Patent Content

[0005] To address the shortcomings of existing technologies, this invention provides a water rescue helmet by modifying the helmet's strap structure and incorporating a water rescue device inside the helmet, thereby increasing the functionality of the traditional helmet and helping individuals wearing the helmet to save themselves after falling into the water.

[0006] The technical solution of this invention patent is as follows:

[0007] A drowning rescue helmet consists of a helmet body, an impact-absorbing liner, a helmet shell, straps, a helmet liner, a drowning rescue device, and a connecting hose.

[0008] The ties include an upper tie and a lower tie, and the upper tie and the lower tie are connected; the liner includes a liner loop and a liner top band, and there is one liner loop and multiple liner top bands.

[0009] The outermost layer of the helmet is the helmet shell, the shock-absorbing liner is located inside the helmet shell, the helmet liner is located inside the helmet body, the upper strap is located between the helmet liner and the shock-absorbing liner, the drowning rescue device is installed between the top strap of the helmet liner, and the upper strap and the drowning rescue device are connected by a connecting hose.

[0010] Furthermore, the strap is a hollow elastic rubber tube structure, which is in a vacuum state under normal use.

[0011] Furthermore, the drowning rescue device consists of a spring chamber, a spring, a quick-dissolving plate, a bottle cap, and a miniature high-pressure gas cylinder. The spring chamber is a cylindrical shell structure, with its lower end connected to the mouth of the miniature high-pressure gas cylinder and its side wall connected to a connecting hose. The spring is installed inside the spring chamber, with one end of the spring in contact with the bottom of the spring chamber and the other end in contact with the quick-dissolving plate. The quick-dissolving plate is located between the spring and the bottle cap, and it fixes the compressed spring inside the spring chamber.

[0012] Furthermore, the bottle cap is a cork frustum structure, with the lower end of the frustum extending into the miniature high-pressure gas cylinder, and the upper end of the frustum in direct contact with the quick-dissolving tablet. After the spring chamber is installed with the mouth of the miniature high-pressure gas cylinder, the free end of the spring applies a force to one side of the quick-dissolving tablet, while the bottle cap applies the same force to the other side of the quick-dissolving tablet, ensuring that the quick-dissolving tablet does not break under normal conditions.

[0013] The effects and benefits of this invention patent are:

[0014] (1) The water rescue helmet is reasonably designed, has a simple structure, does not change the shape and volume of the helmet, and is easy to use;

[0015] (2) Change the structure of the helmet straps and install a water rescue device inside the helmet to increase the functionality of the traditional helmet and help the helmet wearer save himself after falling into the water;

[0016] (3) It increases the functionality of traditional safety helmets and improves their versatility, making them suitable for use in complex construction environments. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] A type of water rescue helmet, as per the instruction manual. Figure 1As shown, it consists of a helmet body 1, an impact-absorbing liner 2, a helmet shell 3, straps, a helmet liner, a drowning rescue device 6, and a connecting hose 7. The straps include an upper strap 41 and a lower strap 42, and the upper strap 41 and the lower strap 42 are connected; the helmet liner includes a helmet liner loop strap 51 and a helmet liner top strap 52, and there is one helmet liner loop strap 51 and multiple helmet liner top straps 52.

[0022] The outermost layer of the helmet body 1 is the helmet shell 3. The shock-absorbing liner 2 is located inside the helmet shell 2. The helmet liner is located inside the helmet body 1. The upper strap 41 is located between the helmet liner and the shock-absorbing liner 2. The drowning rescue device 6 is installed between the top strap 52 of the helmet liner. The upper strap 41 and the drowning rescue device 6 are connected by a connecting hose 7.

[0023] Instruction manual attached Figure 2 As shown, the water rescue device 6 consists of a spring chamber 61, a spring 62, a quick-dissolving plate 63, a cap 64, and a miniature high-pressure gas cylinder 65. The spring chamber 61 is a cylindrical shell structure, with its lower end connected to the mouth of the miniature high-pressure gas cylinder 65 and its side wall connected to a connecting hose 7. The spring 62 is installed inside the spring chamber 61, with one end contacting the bottom of the spring chamber 61 and the other end contacting the quick-dissolving plate 63. The quick-dissolving plate 63 is located between the spring 62 and the cap 64, fixing the compressed spring 62 inside the spring chamber 61. The cap 64 is a cork frustum structure, with the lower end of the frustum extending into the miniature high-pressure gas cylinder 65 and the upper end of the frustum in direct contact with the quick-dissolving plate 63.

[0024] Example

[0025] After the spring chamber 61 is installed at the mouth of the miniature high-pressure gas cylinder 65, the free end of the spring 62 applies a force to one side of the quick-dissolving tablet 63, and the cap 64 applies the same force to the other side of the quick-dissolving tablet 63, so that the quick-dissolving tablet 63 does not break under normal conditions. The drowning rescue device 6 is installed as a functional device between the cap liner straps 52 and is connected to the tie strap through the connecting hose 7.

[0026] In normal use, the straps of the drowning rescue helmet are in a vacuum state. When the wearer accidentally falls into the water, the quick-dissolving tablet 63 dissolves rapidly upon contact with water, and the spring 62 acts directly on the end face of the cap 64, pushing the cap 64 directly into the miniature high-pressure gas cylinder 65. High-pressure gas then enters the upper strap 41 and lower strap 42 directly through the connecting hose 7. The inflated straps increase the helmet's buoyancy, allowing the wearer's head to float on the water's surface.

[0027] The embodiments described above are merely illustrative of implementation methods of this invention and are not intended to limit the concept and scope of this invention. Various modifications and improvements made to the technical solutions of this invention by those skilled in the art without departing from its design concept should fall within the protection scope of this invention, which is defined by the appended claims rather than the foregoing description.
