Description

Technical Field

[0001] This utility model relates to the field of sound and light alarm technology, and in particular to a sealed sound and light alarm for mining. Background Technology

[0002] As a key warning device in the mine safety production system, the audible and visual alarm plays a crucial role in hazard warning and emergency response. Through the dual output of high-decibel alarm sound and high-brightness flashing light, it provides accurate and timely safety prompts to underground workers in dangerous scenarios such as gas leaks, roof abnormalities, fire hazards, and equipment failures, effectively shortening emergency response time and serving as an important guarantee for reducing the casualty rate of mine safety accidents.

[0003] The underground environment of mines is characterized by high dust, high humidity, high vibration, and a confined space. Furthermore, the coal dust and rock dust particles contained within the dust possess both stickiness and abrasiveness. Currently, to meet dust protection requirements, the industry commonly adopts a fully enclosed protective solution using a sealed cover. This involves completely covering the core components of the alarm with a sealed cover made of metal or high-strength engineering plastic, leaving only cable penetration holes for power and signal lines. Even slight cable misalignment during installation can cause gaps. To compensate for these gaps, some manufacturers use a simple method of filling with sealant, but neither of these methods can achieve long-term effective protection.

[0004] However, the sealant used to fill the gap between the cable and the protective cover may age, crack, and fall off over time, resulting in poor dustproof isolation of the audible and visual alarm. This can cause the alarm to malfunction due to dust intrusion at the cable penetration point, directly causing delays in emergency warnings and potentially leading to safety accidents. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a sealed sound and light alarm for mining.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a mine-use sealed audible and visual alarm, including an audible and visual alarm, a dustproof protective component, and a fitting. The audible and visual alarm is externally fitted with a dustproof protective component, which includes a casing cylinder, a mesh cylinder, a transparent lamp tube, and a screw cap. The casing cylinder is vertically fitted onto the outside of the audible and visual alarm, and a mesh cylinder is vertically connected and fixed to the top surface of the casing cylinder. A transparent lamp tube is vertically connected and assembled to the top surface of the mesh cylinder. A screw ring is vertically connected and fixed to the bottom end of the casing cylinder. The internal thread assembly is fitted with a screw cap, and a through hole is opened in the center of the screw cap for connecting with the support rod of the audible and visual alarm. A through-fitting kit is evenly and vertically installed on the screw cap. The through-fitting kit includes an inner threaded tube, pressure plates, an outer threaded tube, and a through-tube. The inner threaded tube is connected and fixed to the bottom surface of the screw cap, and multiple pressure plates are fixed to the end of the inner threaded tube away from the screw cap. The outer threaded tube is sleeved on the outside of the multiple pressure plates and is threaded onto the inner threaded tube. The other end of the outer threaded tube is connected and fixed to the through-tube. The through-tube and the inner threaded tube are used to pass through the guide cable and assemble it on the bottom surface of the audible and visual alarm.

[0007] As a preferred option, a dustproof cotton tube is vertically fitted on the outer side of the mesh cylinder, and the upper and lower sides of the inside of the dustproof cotton tube are fixed to the outer wall of the mesh cylinder.

[0008] As a preferred option, a screw cylinder is vertically connected and fixed at the center of the top surface of the mesh cylinder, and an internal thread is provided on the bottom surface of the transparent lamp tube, and the internal thread is assembled and connected with the screw cylinder thread.

[0009] As a preferred embodiment, a first rubber cylinder is vertically fixed through the inner wall of the screw cap's perforation, and multiple pressure grooves are evenly provided on the outer wall of the first rubber cylinder. An elastic pressure frame is vertically fixed in each of the multiple pressure grooves of the first rubber cylinder, and the other end of the elastic pressure frame is fixed to the inner wall of the screw cap's perforation.

[0010] As a preferred embodiment, a pressure pad is provided on the side of the inner wall of the tablet away from the inner spiral tube, and the pressure pad is fixed on the inner wall of the tablet.

[0011] As a preferred embodiment, multiple raised rings are fixed on the inner wall of the external helical tube in the vertical direction, and the multiple raised rings are used to press multiple pressure plates against the outer wall of the cable.

[0012] As a preferred embodiment, a second rubber cylinder is vertically fixed inside the through cylinder, and multiple elastic plates are vertically arranged between the second rubber cylinder and the through cylinder, with the two sides of the multiple elastic plates respectively fixed to the adjacent end faces of the second rubber cylinder and the through cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The cable penetration point is sealed with a dual elastic sealing structure consisting of a convex ring pressure pad and an elastic rubber sleeve. This ensures a long-lasting seal from the source. Multiple convex rings on the inner wall of the outer spiral tube form the first seal with the pressure pad. The serrated structure of the convex rings can be embedded inside the pressure pad. The pre-tightening force of the threads achieves a circumferential compression of the cable, increasing the sealing contact area compared to sealant. The second rubber sleeve inside the tube forms the second seal with multiple elastic sheets. The continuous deformation force of the elastic sheets keeps the rubber sleeve in close contact with the outer wall of the cable, compensating for gaps caused by slight cable vibration and temperature deformation.

[0015] The dustproof cotton tube outside the casing can filter suspended dust and prevent it from entering the interior through the mesh tube and contaminating the buzzer; the threaded connection between the transparent lamp tube and the screw tube forms an independent sealed space for the lighting rod; the first rubber tube at the screw cap is pressed by the elastic pressure frame to achieve a gapless seal between the support rod and the casing. The sound and light alarm using this technology reduces the failure rate caused by dust intrusion, solves the problem of delayed emergency warning, and eliminates the safety risks caused by equipment failure.

[0016] Through a three-level dustproof design that includes protection of core components, sealing of support rods, and double elastic sealing of cables, the traditional simple sealing method of filling with sealant is completely abandoned. This design specifically addresses core pain points such as rapid seal failure, dust intrusion, and delayed warning, achieving long-term dustproof performance, stable early warning, and low-consumption maintenance for mining audible and visual alarms.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1 to 5 As shown, a mine-use sealed audible and visual alarm includes an audible and visual alarm 1, a dustproof protective component 2, and a through-fitting component 3. The dustproof protective component 2 is assembled and fitted around the outside of the audible and visual alarm 1. The dustproof protective component 2 includes a cover cylinder 21, a mesh cylinder 22, a transparent lamp tube 25, and a screw cap 28. The cover cylinder 21 is vertically fitted around the outside of the audible and visual alarm 1, and the mesh cylinder 22 is vertically connected and fixed on the top surface of the cover cylinder 21. The transparent lamp tube 25 is vertically connected and assembled on the top surface of the mesh cylinder 22. A screw ring 27 is vertically connected and fixed at the bottom end of the cover cylinder 21, and a screw cap 28 is assembled on the internal thread of the screw ring 27. A through hole for connecting the support rod of the audible and visual alarm 1 is opened through the center of the screw cap 28, and through-fitting components 3 are evenly and vertically arranged on the screw cap 28. The through-fitting component 3 includes an inner threaded tube 31 and a pressure... The device consists of a plate 32, an outer threaded tube 34, and a through tube 35. An inner threaded tube 31 is connected and fixed to the bottom surface of a screw cap 28. Multiple pressure plates 32 are fixed to one end of the inner threaded tube 31 away from the screw cap 28. The outer threaded tube 34 is sleeved on the outside of the multiple pressure plates 32 and is threaded onto the inner threaded tube 31. The other end of the outer threaded tube 34 is connected and fixed to a through tube 35. The through tube 35 and the inner threaded tube 31 are used to pass through the guide cable and are assembled on the bottom surface of the audible and visual alarm 1. By setting the technical feature of the dustproof protective component 2, the dustproof protective component 2 includes a cover tube 21, a mesh tube 22, a transparent lamp tube 25, and a screw cap 28. The cover tube 21 is vertically sleeved on the outside of the audible and visual alarm 1. Since the cover tube 21 can effectively block the influence of external dust on the audible and visual alarm 1, it plays a dustproof role. A mesh cylinder 22 is vertically connected and fixed to the top surface of the casing cylinder 21. The mesh cylinder 22 can further screen and filter larger dust particles, enhancing the dustproof effect. A transparent lamp cylinder 25 is vertically connected and assembled to the top surface of the mesh cylinder 22. The use of the transparent lamp cylinder 25 allows the light emitted by the audible and visual alarm 1 to be effectively diffused and transmitted. A screw ring 27 is vertically connected and fixed to the bottom end of the casing cylinder 21, and a screw cap 28 is assembled on the internal thread of the screw ring 27. The screw cap 28 can be tightly fixed to the casing cylinder 21, ensuring the airtightness of the entire device and preventing dust from entering.

[0025] In one embodiment, such as Figure 2 and 3As shown, a dustproof cotton tube 23 is vertically fitted onto the outer side of the mesh tube 22, and the upper and lower sides of the dustproof cotton tube 23 are fixed to the outer wall of the mesh tube 22. A screw cylinder 24 is vertically connected and fixed at the center of the top surface of the mesh tube 22. An internal thread 26 is formed on the bottom surface of the transparent lamp tube 25, and the internal thread 26 is threadedly assembled and connected to the screw cylinder 24. Through the technical features of the dustproof cotton tube 23 and the screw cylinder 24, the dustproof cotton tube 23 can be vertically fitted onto the mesh tube 22 on the outside, effectively preventing dust from entering the inside of the mesh tube 22 and keeping the inside of the mesh tube 22 clean and dry. The fixed connection between the dustproof cotton tube 23 and the mesh tube 22 ensures the reliability and stability of the dustproof effect. The screw cylinder 24 is vertically connected and fixed at the center of the top surface of the mesh tube 22. The thread inside the screw cylinder 24 is threadedly assembled and connected to the internal thread 26 on the bottom surface of the transparent lamp tube 25, which facilitates the installation and removal of the transparent lamp tube 25. This threaded structure design not only ensures the strength and tightness of the connection between the transparent lamp tube 25 and the mesh tube 22, but also makes the entire device more stable and improves the safety of use.

[0026] In one embodiment, such as Figure 3 and 4 As shown, a first rubber cylinder 281 is vertically fixed through the inner wall of the perforation of the screw cap 28, and multiple pressure grooves are evenly formed on the outer wall of the first rubber cylinder 281. An elastic pressure frame 282 is vertically fixed in each of these grooves, with the other end of the elastic pressure frame 282 fixed to the inner wall of the perforation of the screw cap 28. By setting the first rubber cylinder 281 and multiple elastic pressure frames 282, and evenly forming multiple pressure grooves on the outer wall of the first rubber cylinder 281, this structural design allows the elastic pressure frame 282 to deform and press tightly against the hole wall under internal pressure when the screw cap 28 is tightened with the screw sleeve. Therefore, the elastic pressure frame 282 acts as a sealing ring, preventing leakage between the screw cap 28 and the screw sleeve. Specifically, when the elastic pressure frame 282 deforms under pressure, its contact area with the hole wall increases, enhancing the sealing effect. The even distribution of multiple elastic pressure frames 282 not only improves the uniformity of the sealing performance but also...

[0027] In one embodiment, such as Figure 4 and 5As shown, a pressure pad 33 is provided on the inner wall of the pressure plate 32 away from the inner threaded tube 31, and the pressure pad 33 is fixed to the inner wall of the pressure plate 32. Multiple raised rings 38 are fixed vertically on the inner wall of the outer threaded tube 34, and these rings are used to press the multiple pressure plates 32 against the outer wall of the cable. By providing a pressure pad 33 on the inner wall of the pressure plate 32 away from the inner threaded tube 31, and fixing the pressure pad 33 to the inner wall of the pressure plate 32, this technical feature increases the contact area and clamping force with the outer wall of the cable, thus effectively increasing the clamping force and achieving a better cable fastening effect. The design of the pressure pad 33 can evenly distribute the pressure applied to the cable, avoiding damage caused by concentrated pressure that may occur when the pressure plate 32 directly contacts the cable. At the same time, the fixing method of the pressure pad 33 ensures a firm connection with the pressure plate 32, maintaining stability and reliability during the clamping process. Multiple protruding rings 38 are fixed vertically on the inner wall of the external helical tube 34. These protruding rings 38 are used to press multiple pressure plates 32 against the outer wall of the cable.

[0028] In one embodiment, such as Figure 2 and 3 As shown, a second rubber cylinder 36 is vertically fixed inside the through-tube 35, and multiple elastic plates 37 are vertically arranged between the second rubber cylinder 36 and the through-tube 35. The two sides of each elastic plate 37 are fixed to the adjacent end faces of the second rubber cylinder 36 and the through-tube 35, respectively. By setting the second rubber cylinder 36 and fixing it vertically inside the through-tube 35, and simultaneously vertically arranging multiple elastic plates 37 between them, these technical features, through the ingenious use of elastic materials and a multi-plate structure design, achieve multiple functions and thus realize specific technical effects. When the multiple elastic plates 37 between the second rubber cylinder 36 and the through-tube 35 are subjected to external pressure or compression, they can generate elastic deformation, thereby utilizing elastic potential energy to produce a reaction force. This design not only effectively absorbs the impact of external forces but also provides a certain degree of cushioning protection, avoiding damage caused by direct impact.

[0029] The working principle of this utility model:

[0030] First, the cover tube 21 on the dustproof protective part 2 is vertically fitted onto the outside of the body of the sound and light alarm 1. The mesh tube 22 on the top surface of the cover tube 21 is fitted onto the outside of the buzzer of the sound and light alarm 1. In order to prevent dust from entering the inside of the cover tube 21 through the mesh tube 22, a dustproof cotton tube 23 is vertically fitted onto the outside of the mesh tube 22 to prevent dust from entering the inside of the cover tube 21. The transparent lamp tube 25 is vertically fitted onto the lighting rod of the sound and light alarm 1. At the same time, the internal thread 26 at the bottom of the transparent lamp tube 25 is connected and assembled with the screw tube 24.

[0031] Secondly, the screw cap 28 is threaded onto the bottom opening of the cover cylinder 21. The perforation at the center of the screw cap 28 is connected to the support rod on the sound and light alarm 1. The first rubber cylinder 281 is fixed inside the perforation. The deformation force of the elastic pressure frame 282 is used to push the inner wall of the first rubber cylinder 281 to fit tightly against the outer wall of the support rod on the sound and light alarm 1, thus ensuring the sealed insertion of the sound and light alarm 1 and the screw cap 28.

[0032] Finally, the cable is first threaded through the multiple internal helical tubes 31 on the screw cap 28, so that the cable plug end is inserted into the screw cap 28. Then, the external helical tube 34 is rotated and threaded onto the outside of the internal helical tube 31. The multiple convex rings (38) on the inner wall of the external helical tube 34 press against the pressure pad 33 on the inner wall of the pressure plate 32 to form a seal on the outer wall of the cable. At the same time, the second rubber cylinder 36 passing through the inner wall of the cylinder 35 is compressed by the deformation of multiple elastic plates 37 to press the inner wall of the second rubber cylinder 36 tightly against the outer wall of the cable, forming a second seal, thereby sealing the gap between the cable and the inlet hole and improving the dustproof effect.

[0033] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
