Description

Technical Field

[0001] This utility model relates to the field of safety protection device technology, and in particular to a safety protection device for coal mine construction. Background Technology

[0002] Coal mine construction environments are complex, with multiple risks such as gas explosions, roof collapses, dust hazards, and mechanical injuries. Safety protection devices need to form a comprehensive protection system for different risk scenarios, reducing safety risks from multiple dimensions such as environment, equipment, and personnel. Among them, the synergy between ventilation and dust suppression devices and gas monitoring systems has achieved dual protection of "dust control" and "fire and explosion prevention", providing core guarantees for coal mine construction safety.

[0003] An existing coal mine safety protection device (Announcement No.: CN213785648U) has at least the following drawbacks: This device, through the combination of a tension rope and a dust respirator, can prevent workers from inhaling large amounts of dust during coal mining, thus protecting their health. The first locking strip and anti-collision pad provide the helmet with a safety impact protection function, effectively protecting workers' heads and improving its safety performance. However, when the dust respirator is not in use and is taut and upright at the top, the impact force of falling objects will be transmitted to a localized area at the top of the helmet through the rigid connection of the respirator. This concentrated impact force can easily cause danger to the worker's head. Furthermore, sharp fragments from a broken respirator may cut the face and eyes, causing injury to the worker. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a safety protection device for coal mine construction.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coal mine construction safety protection device includes a safety helmet and a main support rubber block. The main support rubber block is integrally installed on the top of the safety helmet. Several impact sensors are fixedly installed inside the main support rubber block along its curve. The bottom of the impact sensors is fixedly connected to the top of the safety helmet. An alarm module and a charging module are provided inside the bottom end of the main support rubber block near the brim of the safety helmet. The charging module is located on the rear side of the safety helmet. An alarm module is provided on the top of the charging module. Two sets of secondary support rubber strips are integrally connected to both sides of the main support rubber block.

[0006] As a further embodiment of this utility model, a warning light strip is installed inside the support strip, and several of the support strips are fixedly connected to the bottom of the top surface of the safety helmet. The warning light is fixedly connected to the control module inside the main support block.

[0007] As a further embodiment of this utility model, the safety helmet is integrally connected to the front side of the mounting frame, the front end of the main support rubber block is provided with a light, the back side bracket of the light is located outside the mounting frame and is fixedly connected to the mounting frame by expansion screws, and a cushioning pad is fixedly connected to the inner wall of the safety helmet.

[0008] As a further embodiment of this utility model, the bottom of the buffer pad is provided with a headband pad and a headrest, both of which are fixedly connected inside the safety helmet. The headrest and the buffer pad are both located on top of the headband pad, and there is a certain gap between the headrest and the buffer pad. Several ventilation holes are provided through both sides of the safety helmet and the headband pad.

[0009] As a further embodiment of this utility model, the safety helmet is provided with a rear headband adjustment strap at the bottom, both ends of which are fixedly connected to the bottom of the safety helmet.

[0018] Reference Figures 1-5A coal mine construction safety protection device includes a safety helmet 1 and a main support rubber block 2. The main support rubber block 2 is integrally installed on the top of the safety helmet 1. Several impact sensors 201 are fixedly installed inside the main support rubber block 2 along its curve. The bottom of the impact sensors 201 is fixedly connected to the top of the safety helmet 1. An alarm module 202 and a charging module 203 are provided inside the bottom end of the main support rubber block 2 near the brim of the safety helmet 1. The charging module 203 is located on the rear side of the safety helmet 1. An alarm module 202 is provided on the top of the charging module 203. Two sets of secondary support rubber strips 3 are integrally connected to both sides of the main support rubber block 2.

[0019] In use, the main support block 2 is integrally protruding from the top of the safety helmet 1. The impact sensor 201 inside is closely attached to the top of the safety helmet 1 to monitor external impact in real time. The support strips 3 are symmetrically distributed on both sides, forming a "support frame" with the main support block 2, which enhances the overall rigidity of the safety helmet 1 and reduces the direct force on the top of the safety helmet 1, preventing the helmet from cracking. When the top is hit by a falling object, the main support block 2 acts as the first barrier, absorbing the impact force through its own elastic deformation. When the impact force is transmitted to the top of the safety helmet 1, the impact sensor 201 is triggered instantly, transmitting the signal to the control module inside the main support block 2. The control module simultaneously activates the internal alarm module 202, which emits a buzzer alarm to warn nearby workers. The impact sensor 201 is linked with the warning system, which can not only promptly remind surrounding workers to assist in the rescue, but also provide alarm signals to the remote monitoring system, shortening the emergency response time.

[0020] In this embodiment, a warning light strip 301 is installed inside the support strip 3, and several strips are fixedly connected from the bottom of the support strip 3 to the top surface of the safety helmet 1. The warning light is fixedly connected to the control module inside the main support block 2.

[0021] When in use, the control module synchronously activates the warning light strip 301 inside the support strip 3, causing the light strip to flash to warn nearby workers. At the same time, it can provide direction for workers who are lagging behind during the escape process, making it easier for workers to find each other and carry out group rescue.

[0022] In this embodiment, the safety helmet 1 is integrally connected to the front side of the mounting bracket 102, the front end of the main support rubber block 2 is provided with a lighting lamp 4, the back side bracket of the lighting lamp 4 is located outside the mounting bracket 102 and is fixedly connected to the mounting bracket 102 by expansion screws, and the inner wall of the safety helmet 1 is fixedly connected with a cushioning pad 103.

[0023] In use, the light 4 is fixed to the mounting bracket 102 on the front of the safety helmet 1 via a clip. The beam can be adjusted to the working surface. The cushioning pad 103 is close to the inner wall of the safety helmet 1, maintaining a slight gap with the head to form a buffer space. The impact force generated by the impact is directed to the main body of the safety helmet 1. The cushioning pad 103 further absorbs energy through compression and deformation, reducing the impact force transmitted to the head. The porous structure of the cushioning pad 103 has both energy absorption and breathability, which not only improves the protective effect but also reduces the stuffiness of wearing it for a long time.

[0024] In this embodiment, the bottom of the buffer pad 103 is provided with a headband pad 5 and a headrest 501. The headband pad 5 and the headrest 501 are both fixedly connected inside the safety helmet 1. The headrest 501 and the buffer pad 103 are both located on the top of the headband pad 5. There is a certain gap between the headrest 501 and the buffer pad 103. Several ventilation holes 101 are provided through both sides of the safety helmet 1 and the headband pad 5.

[0025] When in use, when the impact causes the helmet 1 to tilt or twist to the side, the headband pad 5 elastically contracts and fits tightly against the head to prevent the head from sliding relative to the helmet body. The headrest 501 provides rigid support to the back of the head. Combined with the gap space of the buffer pad 103, the gap space not only enhances breathability but also provides space for the deformation of the buffer pad 103, improving energy absorption efficiency and preventing the back of the head from directly colliding with the helmet body during an impact.

[0026] In this embodiment, the bottom of the safety helmet 1 is provided with a rear band adjustment strap 6, both ends of which are fixedly connected to the bottom of the safety helmet 1. A number of chin straps 7 are provided on one side of the rear band adjustment strap 6, and the number of chin straps 7 are symmetrically distributed on both sides of the bottom of the safety helmet 1 and fixedly connected to the safety helmet 1.

[0027] When in use, the rear hoop adjustment strap 6 is adjusted according to the miner's head circumference and comfort, making it convenient for the miner to wear. In the event of an impact, the rear hoop adjustment strap 6 remains taut to prevent the safety helmet 1 from shifting or falling off.

[0028] In this embodiment, several jaw straps 7 are interlocked at their bottom ends for positioning. A jaw pad 701 is fixedly connected to the top of the insert of the jaw strap 7. A goggle 8 is provided on the front side of the jaw strap 7. The elastic bands at both ends of the goggle 8 are fixedly connected to the top of the jaw strap 7 by bolts.

[0029] In use, the chin strap 7 is fixed by plug-in connection, and the chin pad 701 silicone material fits the chin area to distribute local pressure. The goggles 8 are fixed to the front of the helmet 1 by elastic bands, covering the eye area. The goggles 8 use the elasticity of the elastic bands to resist the lateral force during impact, preventing the lens from falling off or breaking. At the same time, it blocks flying coal dust and gravel from entering the eyes, solving the problem of traditional goggles 8 being easy to fall off and improving the reliability of eye protection.

[0030] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When a falling object hits the safety helmet 1, the main support block 2 at the top absorbs the impact force through elastic deformation. This, along with the "support frame" formed by the support strips 3 on both sides, enhances the rigidity of the helmet to prevent cracking, thus providing a buffer for subsequent protection. When the impact force is transmitted to the helmet, the impact sensor 201 triggers the control module, activating the warning light strip 301 (flashing red light) and the sound alarm module 202 (buzzer) inside the support strips 3 for dual... A strong warning is issued, and a signal is simultaneously transmitted to remote monitoring. After the initial buffering of the remaining impact force, it is transmitted to the inner wall. The buffer pad 103 reduces the force on the head through compression and deformation. The headband pad 5 elastically contracts to prevent the head from sliding. The headrest 501, in conjunction with the gap space, forms a "two-way buffer" to improve energy absorption efficiency. At the same time, the rear band adjustment strap 6 is tightened to prevent the cap from falling off, the chin strap 7 is tightened and fixed with a plug, and the chin pad 701 disperses pressure to avoid strangulation. In addition, the goggles 8 use elastic bands to buffer lateral forces, and the bolt-fixed structure ensures that they block flying debris and protect the eyes. The entire process constructs a complete protective chain to reduce injury through a synergistic mechanism of "gradual impact absorption, immediate signal warning, stable cap fixation, and comprehensive protection of details."

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
