Description

Technical Field

[0001] This utility model relates to the field of telephone technology, specifically to an intrinsically safe automatic telephone for mining applications with direct connection and self-detection of disconnection. Background Technology

[0002] A telephone is a communication device that converts sound into electrical signals and transmits them over telephone lines or networks to distant locations. It mainly consists of a handset, microphone, dialing device, and ringing system, allowing people in different places to talk in real time. From the initial rotary dial to today's keypad, and then to video phones and smartphones, telephone technology has been constantly innovating, but the core has always been to break spatial limitations and achieve instant voice communication, which has greatly changed the way people communicate and the pace of life.

[0003] Intrinsically safe automatic telephones for mining are communication devices specifically designed for hazardous environments such as underground mines. Their most significant feature is their intrinsically safe circuitry, which effectively prevents accidents caused by electrical sparks. Their "straight-through" function ensures rapid, uninterrupted calls in emergencies, while their "line breakage self-test" function continuously monitors the line status and immediately alarms upon detecting an interruption, ensuring the reliability of the communication link. These telephones are robustly constructed and can operate stably in harsh conditions such as humidity and dust, making them a crucial communication tool for ensuring safe production and emergency rescue in mines.

[0004] However, existing intrinsically safe automatic telephones for mining with direct connection and self-diagnosis of disconnection, especially those with traditional fixed connections, are prone to damage to their internal precision electronic components when subjected to impacts and vibrations from mining equipment operation or falling rocks. This leads to an increased equipment failure rate and the inability to achieve multi-level anti-eccentric load. Uneven stress during installation or use can cause stress concentration, resulting in problems such as casing deformation and internal circuit board breakage over time, shortening the service life. Furthermore, the equipment cannot be optimized for different working conditions and is prone to failure due to vibration or loosening, requiring frequent maintenance and replacement, increasing operation and maintenance costs and downtime. To address these issues, this paper proposes an intrinsically safe automatic telephone for mining with direct connection and self-diagnosis of disconnection. Utility Model Content

[0023] 1. This utility model provides an intrinsically safe automatic telephone for mining with a straight-through connection and self-detection of broken wires. First, the linkage between the bidirectional threaded rod, single-groove synchronous pulley, double-groove synchronous pulley, synchronous belt, worm gear, worm, nut pair, slider, steel spring and sealing plate ensures uniform force distribution under the telephone, avoids local overload damage, effectively absorbs impact vibration, protects internal precision components from the vibration of mining machinery, and ensures that the buffer force is perfectly matched with the actual working conditions, thus improving the adaptability of the equipment.

[0032] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figure 1 , Figure 2 and Figure 4This utility model discloses an intrinsically safe automatic telephone for mining applications with a direct connection and self-detection of line breakage. It includes a mounting plate 1, which allows the entire device to be installed in a designated location. A housing 16 is fixedly connected to the top of a connecting block 15, protecting the internal structure. A telephone 21 is mounted on one end of the inner wall of the housing 16, and a detection light 23 is mounted on the top of the telephone 21, penetrating the housing 16. The detection light 23 receives signals from the line; if no signal is received from the exchange within a specified time, the line is considered broken, and the detection light 23 is activated as an alarm. A direct connection button 22 is mounted on one end of the telephone 21. When pressed, the internal circuitry of the telephone 21 bypasses normal dialing and automatically calls a preset emergency number, enabling one-button emergency call. A door 17 is mounted on one end of the housing 16 to prevent external dust from entering the housing 16.

[0035] Reference Figure 1 and Figure 2 One end of the mounting plate 1 is rotatably connected to a uniformly distributed bidirectional threaded rod 2. One end of the middle bidirectional threaded rod 2 is rotatably connected to a double-groove synchronous pulley 4. One end of each of the two bidirectional threaded rods 2 is rotatably connected to a single-groove synchronous pulley 3. A synchronous belt 5 is provided between each of the single-groove synchronous pulley 3 and the double-groove synchronous pulley 4. One end of one single-groove synchronous pulley 3 is rotatably connected to a worm gear 6. A worm 7 is rotatably connected to one side of the mounting plate 1, and the worm 7 meshes with the worm gear 6. The rotation of the worm 7 causes the worm gear 6 to drive the single-groove synchronous pulley 3 on the mounting plate 1 to rotate. Then, through the transmission of the synchronous belt 5, the single-groove synchronous pulleys 3 and double-groove synchronous pulleys 4 on both sides rotate synchronously on the mounting plate 1, thereby causing the bidirectional threaded rod 2 to rotate synchronously on the mounting plate 1, thus synchronously driving both... The end nuts 8 are brought closer together or further apart, allowing for fine-tuning to ensure the buffer force perfectly matches the actual working conditions, improving equipment adaptability. A rocker arm, which passes through and slides through one end of the worm gear 7, slides into the worm gear 7 when needed, thus driving the worm gear 7 to rotate. A slider 9 is passed through and slidably connected to the top of the mounting plate 1. The outer ring of the bidirectional threaded rod 2 is threaded with nut assemblies 8 at both ends, and the nut assemblies 8 are slidably connected to the mounting plate 1. Steel springs 10 are sleeved at both ends of the outer ring of the bidirectional threaded rod 2. A sealing plate 11 is fixedly connected to the top of the slider 9. A disassembly component is provided on one side of the sealing plate 11. By sliding the nut assemblies 8, the steel springs 10 are compressed, causing the slider 9 to move on the mounting plate 1, thus effectively absorbing impact vibration and protecting the internal precision components from the vibration of mining machinery.

[0036] Reference Figures 3-5The disassembly assembly includes a fixing rod 12, which is slidably connected to one end of a sealing plate 11. Each fixing rod 12 has a first spring 13 inside, and one end of each first spring 13 is fixedly connected to a limiting rod 14, which is slidably connected to the fixing rod 12. The limiting rod 14 is also slidably connected to the sealing plate 11. Connecting blocks 15 are slidably connected to the top perimeter of the sealing plate 11, and are also slidably connected to the fixing rod 12 and the limiting rod 14. By allowing the limiting rod 14 to slide out of the sealing plate 11 and into the fixing rod 12, the first spring 13 is compressed, causing the fixing rod 12 to slide out of the sealing plate 11 and then out of the connecting block 15. This eliminates the need for complex tools and reduces the risk of accidents in dimly lit, confined downhole environments. To reduce operational difficulty and personnel risks, a baffle 20 is fixedly connected to one end of the door 17, and the baffle 20 contacts the housing 16. Evenly distributed lamp tubes 25 are arranged on both sides of the inner wall of the housing 16. A sensor 24 is installed inside the housing 16 and is electrically connected to the lamp tubes 25. A support rod 18 is slidably connected through the bottom of the inner wall of the housing 16, and the support rod 18 contacts the baffle 20 and the sensor 24. A second spring 19 is fitted around the outer ring of the support rod 18. When the door 17 is closed, the baffle 20 slides into the housing 16, thus squeezing the support rod 18, which in turn squeezes the second spring 19. This causes the protrusion at the bottom of the support rod 18 to contact the sensor 24, causing the sensor 24 to drive the lamp tubes 25 to turn off. This ensures that lighting is only provided when needed, effectively saving energy and extending the lifespan of the lamp tubes 25.

[0037] Working principle: By allowing the connecting block 15 to slide into the sealing plate 11, and then allowing the limiting rod 14 to slide into the fixing rod 12, the first spring 13 is compressed. The fixing rod 12 then slides into the mounting plate 1 and passes through the connecting block 15, subsequently moving to a designated position. Then, due to the rebound of the first spring 13, the limiting rod 14 slides out of the fixing rod 12 and into the sealing plate 11, thus fixing the required components and structure. The worm gear 7 then rotates on the mounting plate 1, and through the meshing connection between the worm gear 7 and the worm wheel 6, the worm wheel 6 drives one side of the single-groove synchronous pulley 3 to rotate on the mounting plate 1. Then, through the transmission of the synchronous belt 5, the other side... The single-groove synchronous pulley 3 and the double-groove synchronous pulley 4 rotate synchronously on the mounting plate 1, thereby causing the bidirectional threaded rod 2 to rotate synchronously on the mounting plate 1. This causes the bidirectional threaded rod 2 to drive the nut assembly 8 to move synchronously on the mounting plate 1, thus compressing the steel spring 10. Subsequently, the rebound of the steel spring 10 adjusts the buffering capacity of the slider 9. When the door 17 is opened, the baffle 20 can slide out of the housing 16, thereby releasing the bearing rod 18. Then, the rebound of the second spring 19 causes the bearing rod 18 to move on the housing 16, thereby separating the bottom protrusion of the bearing rod 18 from the sensor 24, allowing the sensor 24 to drive the lamp tube 25 to illuminate the required equipment.
