Description

Technical Field

[0001] The present invention belongs to the technical field of rescue and protection, and specifically relates to a protective device used for assisting operations and rescue in an environment with a risk of collapse. Background Art

[0002] There is a risk of collapse during operations in trenches, foundation pits, stockpiles and other places. Once collapse occurs, it will pose a life-threatening risk to the buried people. For example, there is a strong external impact force, people cannot breathe in a relatively closed environment, the specific buried location is difficult to determine, communication is impossible, the use of excavation tools can easily cause harm to the buried people, and the resulting rescue difficulties, it is difficult to use large machinery to participate in the rescue, and the injured cannot get medical treatment in a short time.

[0003] Conventional safety helmets mostly use a single hard shell structure and lack a multi-level buffering mechanism. During a collapse, the impact force of falling objects is directly transmitted to the head, which can easily cause craniocerebral injuries. In addition, existing chest protectors are mostly fixed and cannot adjust the protective space, which increases the possibility of external compression of the chest cavity after being buried, leading to restricted breathing or even suffocation. In addition, it is often impossible to provide external rescuers with the approximate position and posture of the buried person, and it is impossible to provide psychological comfort to them during the rescue, and provide emotional value to the trapped people. Summary of the invention

[0004] The purpose of the present invention is to provide a protective device for assisting operations and rescue in an environment with a risk of collapse, so as to solve the problems raised in the above-mentioned background technology.

[0035] Principle of operation or structural principle: When using rescue and protection equipment, lift the chest component 2 with both hands, put the user on from below the chest component 2, pass the head through the collar 203 formed by the front chest plate 201 and the back plate 202. The material at the position of the front chest plate 201 and the back plate 202 close to the collar 203 is divided into two layers. The outer layer is made of high-elastic polyester fiber to increase wear resistance, and the inner layer is made of neoprene material. The arms pass through the cuffs 204 provided on both sides, and the material near the cuffs 204 is aramid material, which will not affect the neck and arms during the construction of workers, enabling workers to construct normally. Moreover, the material for chest protection of the front chest plate 201 and the back plate 202 is carbon fiber composite material. Then, fasten the head component 1 on the head. The soft protection layer provided on the inner side of the helmet inner layer 108 abuts against the top of the head, and there are multiple groups of ventilation holes 109 on the helmet inner layer 108. The ventilation holes 109 are used to ventilate the head. After fastening the helmet inner layer 108 on the head, manually pull the lower jaw tightening strap 103 and pull it down to clamp on the chin, so as to stably fix the helmet body 101 on the head. A protective mask 102 is fixedly installed in front of the helmet body 101. The protective mask 102 is made of hard transparent material and is used to protect the face to prevent the face from being buried during a collapse. And a solid desiccant is arranged at the position near the mouth and nose on the inner side of the protective mask 102 to avoid the aggregation of water vapor blocking the line of sight. And a microphone and a speaker are respectively arranged on both sides of the helmet body 101 for external communication;

[0036] And a battery is arranged inside the helmet body 101. The battery can supply power to the lighting lamp installed inside the helmet body 101. When being buried during a collapse, the pressure sensor (model: MLH03KPSB06A) senses the transmitted pressure, releases a signal to the controller, and the controller controls the lighting lamp to continuously emit light to provide light for the buried person, calming their mind. And the upper side of the helmet inner layer 108 is fixedly connected to the damping rod 106 and the damping spring 107. The damping rod 106 and the damping spring 107 are connected to the inner side of the helmet body 101. When the helmet body 101 is hit by an object falling from above, it can buffer the head;

[0037] An air storage cavity is provided inside the front chest plate 201 and the back chest plate 202. An air inflation hole is installed on one side of the air storage cavity to inject air into the air storage cavity, and a one-way valve is provided on the air inflation hole to prevent the air in the air storage cavity from leaking. One side of the air storage cavity is connected through a trachea 211 provided. A protective layer is arranged on the outer circle of the trachea 211 to prevent the trachea 211 from losing its air conduction function due to external forces. One end of the trachea 211 far from the air storage cavity is connected to one side of the helmet main body 101. When the staff is buried, the trachea 211 conveys air into the helmet main body 101 to provide air for the staff. A gas pressure sensor is installed on the upper part of the air storage cavity. The gas pressure sensor (SDP810-500PA) is electrically connected to the battery for power supply. The battery is installed on the front chest plate 201. A protective plate is arranged in front of the battery to protect the battery. To ensure that there is enough air in the air storage cavity, a pressure gauge (model BD-93S) is arranged at the upper part of the back chest plate 202 corresponding to the position of the left shoulder of the staff. The pressure gauge is connected to the air storage cavity to monitor the air in the air storage cavity and display the pressure of the internal air;

[0038] When the staff is buried, the pressure is sensed by a pressure sensor provided on one side of the front chest plate 201, and a signal is transmitted to the controller. The controller controls and drives a drive motor 206 (model EC-4pole22) fixed in a fixed frame 205. The drive motor 206 drives the threaded rod 207 to rotate. The rotation of the threaded rod 207 drives the threaded block 208 to slide on one side of the front chest plate 201. One side of the threaded block 208 far from the front chest plate 201 is fixed on a sliding guide frame 209, driving the sliding guide frame 209 to slide inside the fixed frame 205. One side of the sliding guide frame 209 is fixed on the front chest plate 201, thereby driving the front chest plate 201 away from the back chest plate 202 to provide a protection space for the chest of the buried person. At the same time, the air storage cavity conveys air into the helmet main body 101 through the connected trachea 211 to provide sufficient air for the buried person;

[0039] A battery and a circuit board are provided inside the display housing 301. When the worker is buried, the position is located through a GPS module (U-bloxNEO-M8N) provided and a signal is sent to a signal receiver provided on the display housing 301, causing an alarm on the display housing 301 to sound for warning. Communication can be carried out with the trapped person through a communication speaker provided on the display housing 301. The display screen 303 provided on the display housing 301 receives the buried signal and displays the positions of the head assembly 1 and the chest assembly 2 from the external display assembly 3, so as to quickly determine the position of the buried person and implement a rescue.

[0040] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
