Description

Technical Field

[0001] This application relates to the field of receiver technology, and more particularly to an intrinsically safe receiver for mining applications. Background Technology

[0002] In mining environments, receivers are an important component of communication systems, and their performance and stability directly affect the safety and efficiency of mine production. However, traditional mining receivers are inadequate in terms of explosion-proof, drop-proof, and heat dissipation. Especially in dusty environments, dust easily accumulates in the receiver's heat dissipation holes, affecting heat dissipation and even causing equipment failure. Therefore, it is particularly important to develop a mining receiver that is both explosion-proof and drop-proof, as well as effective in heat dissipation and dust prevention. Utility Model Content

[0003] The problem this application aims to solve is that existing receivers, while meeting explosion-proof requirements, cannot simultaneously achieve heat dissipation and dustproof performance.

[0004] To address the aforementioned technical problems, this application provides an intrinsically safe receiver for mining applications, comprising a receiver body made of engineering plastic, which is explosion-proof and drop-proof; a through-hole on one side of the body for ventilation and heat dissipation; a fan located at the through-hole for active heat dissipation; and a cover plate added at the through-hole for shielding, the cover plate consisting of an outer plate and an inner plate. The outer plate is located at the through-hole and can rotate around it, with evenly distributed slots on its surface and a groove formed inside the outer plate. An inner plate, concentrically connected to the outer plate, is arranged inside the groove and fixedly connected to the through-hole. The inner plate also has slots on its surface. When the two sets of slots overlap, the through-hole can be ventilated and cooled by the fan. When the two sets of slots are misaligned, the through-hole is blocked, preventing dust from entering the body.

[0005] Because the intrinsically safe receiver of this application is designed with a fan and a cover plate, it achieves multiple functions such as explosion-proof, drop-proof, good heat dissipation and effective dust prevention by optimizing the structural design. This solves the problem that the receivers of the prior art cannot simultaneously meet the requirements of explosion-proof performance while also ensuring heat dissipation and dust prevention performance.

[0011] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0012] This application relates to an intrinsically safe receiver for mining applications, such as... Figure 1-5 As shown, the receiver includes a receiver body 1, which is made of engineering plastic to ensure explosion-proof and drop-proof performance. An outwardly extending antenna 2 is arranged on one side of the body for receiving signals. Screw holes 3 are arranged around the body to facilitate fixing the receiver to mining equipment or walls. A cover plate 4 is arranged on the top of the body and can be detachably connected to it to facilitate the installation and maintenance of internal components. An interface for connecting to the bus is arranged on the top of the body to realize the connection with the mining communication system.

[0013] A through hole 6 is provided on one side of the machine body for ventilation and heat dissipation. A fan 7 is arranged at the through hole 6 to perform active heat dissipation. A cover plate is also added at the through hole 6 to provide a shielding function. The cover plate consists of an outer plate 8 and an inner plate 9. The outer plate 8 is arranged at the through hole 6 and can rotate around it. The surface of the outer plate 8 is evenly arranged with slots 10. A groove is formed inside the outer plate 8. The inner plate 9 is arranged inside the groove and is concentrically connected to the outer plate 8. The inner plate 9 is fixedly connected to the through hole 6. The surface of the inner plate 9 is also formed with slots 10. When the two sets of slots 10 overlap, the through hole 6 can perform ventilation and heat dissipation with the help of the fan 7. When the two sets of slots 10 are misaligned, the through hole 6 is blocked to prevent dust from entering the machine body.

[0014] The inner plate 9 has a first motor 11 that is keyed to the outer plate 8. The first motor 11 drives the outer plate 8 to rotate around the through hole 6, so as to realize the opening and closing of the slot 10 between the outer plate 8 and the inner plate 9. The fan 7 and the first motor 11 are coordinated to operate by means of a PLC controller. When the slot 10 is open, the fan 7 runs to dissipate heat. The operation of the first motor 11 can be realized by means of a temperature sensor or timer connected to the PLC controller. The opening and closing state of the cover is automatically adjusted according to the internal temperature of the machine or the set time. Since the motor and sensor control of the PLC controller is common knowledge, it will not be described in detail.

[0015] Both the body and cover plate 4 are made of engineering plastics to meet the safety requirements of mine explosion-proof and drop-proof. Active heat dissipation is achieved through the fan 7, which effectively reduces the internal temperature of the body and ensures stable operation of the receiver. The cover plate design can effectively prevent mine dust from entering the body and protect the internal components from damage. The PLC controller realizes the coordinated movement of the fan 7 and the first motor 11, and automatically adjusts the heat dissipation and dust prevention status according to actual needs, thereby improving the intelligence level of the receiver.

[0016] The fan 7 consists of a housing 12, blades 13, and a second motor 14, forming a complete heat dissipation device. The housing 12 is bolted to the body, ensuring that the fan 7 is securely mounted on the body and facilitating disassembly and maintenance. The second motor 14 and blades 13 are arranged inside the housing 12, forming a compact fan 7 structure. The second motor 14 is fixedly connected to the housing 12, ensuring that the motor will not shake or shift during operation. It is tightly connected to the output shaft of the second motor 14. The rotation of the motor drives the blades 13 to rotate, thereby generating airflow for heat dissipation. The second motor 14 (responsible for driving the fan 7 blades 13) and the first motor 11 (responsible for driving the housing rotation) share the power supply inside the receiver. This design simplifies the receiver's power system, reduces the number and complexity of power cables, and improves the overall reliability and maintainability of the receiver. The shared power supply, through reasonable circuit design and power management strategies, ensures that the two motors can work simultaneously or independently when needed, meeting the receiver's heat dissipation and dust prevention requirements.

[0017] The PLC controller not only coordinates the operation of the fan 7 and the second motor 14, but also manages the start and stop operations of the first motor 11. Through the integrated control system, the receiver can automatically adjust the speed of the fan 7 and the opening and closing status of the cover plate according to the internal temperature, external dust concentration or preset time period, so as to realize intelligent heat dissipation and dust prevention control. The control system also has fault detection and alarm functions. When the fan 7 or the motor fails, it can issue an alarm in time and take corresponding emergency measures to ensure the safe and stable operation of the receiver.

[0018] The bolted connection design between the fan 7 and the casing, as well as the arrangement of the motor and blades 13 inside the casing 12, makes the overall structure of the receiver more compact, facilitating installation and arrangement in limited spaces. The design of the second motor 14 and the first motor 11 sharing a power supply simplifies the receiver's power system, reduces costs and maintenance difficulty, and the integrated control system enables intelligent management of the fan 7 and the casing, improving the receiver's automation level and ability to cope with complex environments. Through reasonable structural design and power management strategies, as well as fault detection and alarm functions, the long-term stable operation of the receiver is ensured, reducing downtime and maintenance costs caused by faults.

[0019] When using the receiver, first, select a suitable installation location based on the actual needs of the mine site. Ensure the installation location is stable, well-ventilated, and away from potential sources of explosive gases. Use the screw holes 3 around the receiver to fix it to the mining equipment or wall with bolts, ensuring a secure fixation to prevent the receiver from shaking or falling off during use. Extend and fix the antenna 2 in the specified direction, ensuring that the antenna 2 can receive a clear signal. Use a suitable connecting cable to connect the bus interface 5 on the top of the receiver to the mine communication system, ensuring a reliable connection to prevent interference or loss of signal during transmission. Connect the receiver's power cord to the mine's power system, ensuring that the power supply voltage and current meet the receiver's requirements to prevent damage from overvoltage or overcurrent. Check that the power connection is secure to ensure that the receiver will not be interrupted during operation due to power problems. When using the receiver for the first time, initialization settings are required. According to the receiver's instruction manual, set the relevant parameters, such as communication frequency and baud rate, to ensure correct settings and prevent errors or malfunctions during communication.

[0020] The receiver generates heat during operation, which needs to be dissipated by fan 7. Ensure the bolts connecting the fan 7 cover 12 to the main body are secure to prevent shaking or noise during operation. Adjust the cover's opening and closing status regularly according to the dust concentration at the mine site. When the dust concentration is high, close the cover to prevent dust from entering the receiver; when the dust concentration is low, open the cover to enhance heat dissipation. Regularly check the operation of fan 7 and the motor to ensure they are in good working order. If any abnormalities or malfunctions are found, repair or replace them promptly. Regularly clean and maintain the receiver, keeping its surface and interior clean and preventing dust from entering. To prevent dust, oil, and other impurities from damaging the receiver, check that all components of the receiver are intact, such as antenna 2, screw holes 3, cover plate 4, and fan 7. If any damage or wear is found, replace or repair it promptly. Regularly test and verify the receiver's performance to ensure its communication quality and stability. If any performance degradation or abnormality is found, adjust or repair it promptly. During use, strictly abide by the mine's safety regulations and operating procedures to ensure the safe use of the receiver. Avoid using the receiver in explosive gas environments to prevent safety accidents. In case of thunderstorms or other severe environmental conditions, the receiver should be turned off promptly and stored properly to avoid damage or malfunction.
