Description

Technical Field

[0001] This utility model belongs to the technical field of mining lighting equipment, specifically relating to a mining explosion-proof lamp. Background Technology

[0002] In underground working environments such as coal mines and metal mines, lighting equipment is a crucial tool for ensuring personnel safety and must possess excellent explosion-proof performance, stable power supply connectivity, superior heat dissipation, and impact resistance. However, existing mine explosion-proof lights generally suffer from the following shortcomings: On the one hand, some mine explosion-proof lights lack flexible adjustment capabilities in their installation structure, and the lamp body is fixed in a single way, making it difficult to achieve precise adjustment of the illumination angle. This results in incomplete coverage of the lighting area and reduces the visibility and safety of underground operations.

[0003] On the other hand, the connection structure between the lamp body and the power cord in existing devices generally adopts a simple wire channel or exposed wiring method, which is prone to problems such as cable loosening, water ingress, and pressure damage during long-term use, affecting explosion-proof performance and power supply stability.

[0004] Furthermore, as high-energy-density light-emitting devices, LEDs generate heat during operation. If this heat is not dissipated in time, the internal temperature of the lamp will rise rapidly. This not only affects the luminous efficiency and lifespan of the LEDs but may also increase the risk of structural failure due to thermal expansion and contraction. Currently, most explosion-proof lamps lack effective multi-stage heat dissipation channels in their structure. The heat dissipation components are unevenly distributed or have a simple structure, resulting in low overall heat dissipation efficiency and limiting the stable application of explosion-proof lamps in high-temperature environments.

[0005] Furthermore, mines and other similar locations pose risks such as falling objects and mechanical collisions. Existing explosion-proof lights mostly use rigid outer shells for protection and lack protective layers with elastic buffering or impact absorption capabilities. Once subjected to severe impacts, the lights are easily damaged, affecting their normal operation and even causing safety accidents.

[0006] In summary, existing mine explosion-proof lights still have room for improvement in terms of illumination angle adjustment, cable wiring, explosion-proof sealing, structural heat dissipation, and impact resistance. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a mine explosion-proof lamp that is structurally sound, functionally versatile, and suitable for the harsh environment of mines, thus meeting practical application needs.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A mine explosion-proof light includes a base, the base including a connecting ring, a main pipe communicating with the outer side of the connecting ring, a fixed seat at one end of the main pipe, and the angle between the main pipe and the fixed seat can be adjusted. The top of the connecting ring is provided with a top cover, and the bottom of the connecting ring is provided with a base, and the base is provided with a lamp panel inside. Furthermore, a protective mechanism is provided at the bottom of the base. The protective mechanism includes a sealing cover that is sealed and connected to the base. A protective cover is provided outside the sealing cover. A heat-conducting plate is provided between the sealing cover and the protective cover. The heat-conducting plate is distributed at equal intervals around the central axis of the sealing cover.

[0009] Furthermore, the heat-conducting plate is configured to be corrugated; the heat-conducting plate is used to transfer the heat of the sealing cover to the protective cover, and can prevent the impact force on the protective cover from being transferred to the sealing cover.

[0010] Furthermore, the protective cover has through slots that are evenly distributed around the central axis of the protective cover.

[0011] Furthermore, an inlet pipe is fixedly connected to the main pipe and passes through it. The wire passes through the inlet pipe and the main pipe and enters the connecting ring so as to be connected to the lamp panel.

[0012] Furthermore, a ball head is fixedly connected to one end of the main tube, and the ball head is inserted into the fixed seat; The mounting base is equipped with a locking cover, which is used to lock the position of the ball head; A fixing plate is fixedly connected to one end of the fixing base, and the fixing plate is fixed to the tunnel wall by screws.

[0013] Furthermore, the inner ring of the base is provided with a limit ring, and the lamp panel is connected to the limit ring using screws; A heat sink is fixedly connected to the outer side of the base, and the heat sink is evenly distributed around the central axis of the base.

[0014] Furthermore, the outer side of the top cover is provided with heat dissipation strips, which are evenly distributed around the central axis of the top cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention achieves flexible adjustment and reliable fixation of the lamp's illumination angle by setting a ball head structure at one end of the main tube, inserting the ball head into the fixing seat, and locking it with a locking cover. This overcomes the problems of the existing mine explosion-proof lamps, such as the inability to accurately adjust the lighting direction and the limited illumination coverage, and improves the applicability and safety of the lamps in complex tunnel scenarios.

[0016] This utility model forms a closed cable channel by connecting the inlet pipe to the main pipe, allowing the cable to pass through the inlet pipe, reach the connecting ring through the main pipe, and finally connect to the lamp panel. This achieves sealed protection for the internal wiring and effectively solves the technical problems of poor cable inlet sealing, susceptibility to moisture and gas intrusion, and unstable power supply in existing explosion-proof lamp structures. It also improves the safety and reliability of explosion-proof electrical connections.

[0017] This invention ensures stable installation of the LED light source under long-term vibration and impact conditions by setting an annular limiting ring around the lamp panel and fixing the lamp panel with screws. It solves the problem of easy displacement or loosening of the internal lamp panel of existing explosion-proof lights, improves the overall structure's anti-interference and stability, and ensures stable output of the light source.

[0018] This invention constructs a coordinated heat dissipation path by setting heat dissipation plates at equal intervals on the outside of the base, setting heat dissipation strips on the outside of the top cover, and forming thermal conduction contact between the lamp panel and the base. This improves the heat dissipation efficiency of the lamp in the sealed structure, overcomes the problem of excessive temperature rise and shortened life of LED light source caused by the single heat dissipation structure of existing explosion-proof lamps, extends the service life of the lamp and ensures its reliable operation in high-temperature environments.

[0019] This utility model incorporates a protective mechanism consisting of a three-layer structure: a sealing cover, a protective cover, and a heat-conducting plate. The sealing cover is made of high-strength transparent material, the protective cover is made of metal mesh, and the heat-conducting plate is wavy and positioned between the two, thus combining heat conduction and buffering functions. This solves the problem of existing explosion-proof lights having a simple structure and weak buffering capacity in terms of impact protection, enhances the overall impact resistance of the light fixture, and reduces the risk of damage caused by collisions during mining operations.

[0020] This invention effectively promotes the discharge of internal hot air and enhances air convection by setting an circumferential groove on the protective cover and forming an airflow path after the heat conduction plate conducts heat. This overcomes the problems of poor ventilation and heat accumulation in the existing structure, improves the heat dissipation efficiency under the protective structure, and ensures that the whole lamp achieves a good balance between protection and heat dissipation.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] See Figure 1-6 A mining explosion-proof light includes a base 1, which includes a connecting ring 11. A main pipe 12 is provided on the outer side of the connecting ring 11 and communicates with it. A fixing seat 14 is provided at one end of the main pipe 12, and the angle between the main pipe 12 and the fixing seat 14 can be adjusted. The other end of the main pipe 12 is fixedly connected to the connecting ring 11, forming a through-line structure between the light fixture and the power cord. The fixing seat 14 has a multi-angle adjustment function through an internal ball joint connection structure, which can adjust the lighting direction according to different needs of the usage scenario. A top cover 5 is provided on the top of the connecting ring 11 to seal the upper part of the light body and assist in heat dissipation. A base 2 is provided at the bottom of the connecting ring 11, and a light fixture is provided inside the base 2. The lamp panel 3 is installed on the limiting ring of the inner ring of the base 2 and is fastened with screws to ensure that the lamp panel 3 still works stably in high impact and high vibration environments. The bottom of the base 2 is provided with a protective mechanism 4, which includes a sealing cover 41 sealed to the base 2. The sealing cover 41 is used to cover the lamp panel and achieve dustproof, waterproof and gas penetration prevention. A protective cover 42 is provided outside the sealing cover 41. The protective cover 42 is a metal mesh structure to enhance the external impact resistance. A heat conduction plate 43 is provided between the sealing cover 41 and the protective cover 42. The heat conduction plate 43 is evenly distributed around the central axis of the sealing cover 41 to form a dual-function structure of uniform heat conduction and buffer protection.

[0025] See Figure 5The heat-conducting plate 43 is designed to be corrugated. The heat-conducting plate 43 is used to transfer the heat of the sealing cover 41 to the protective cover 42, thereby improving the heat dissipation efficiency and preventing heat from accumulating in the sealed area and causing a temperature rise. The heat-conducting plate 43 is made of a metal material with good thermal conductivity and a certain degree of elasticity. Its corrugated structure can produce elastic deformation when subjected to external impact, effectively absorbing impact energy and preventing the impact force on the protective cover 42 from being directly transferred to the sealing cover 41, thereby improving the impact resistance of the entire lamp body and extending the service life of the lamp.

[0026] See Figure 5 A through groove 421 is provided on the protective cover 42, and the through groove 421 is evenly distributed around the central axis of the protective cover 42. The through groove 421 is used to guide the internal hot air to be discharged quickly during the operation of the lamp. With the conduction of the heat conduction plate 43, a smooth heat dissipation airflow channel is formed. The size and arrangement of the through groove 421 have been optimized to ensure air circulation and maintain the overall structural strength of the protective cover, avoiding the problem of local weakness of the protective cover due to excessive through groove.

[0027] See Figure 1-3 The main pipe 12 is fixedly connected to an inlet pipe 122 that is connected to it, and the inlet pipe 122 and the main pipe 12 form an integrated wiring channel. The wire passes through the inlet pipe 122 and the main pipe 12 and enters the connecting ring 11. After the cable is sealed and wired, it is finally connected to the lamp panel 3 set inside the base 2, so as to realize the reliable power supply of the whole lamp. The sealing and pressure resistance design of the inlet pipe 122 can effectively prevent the humid, high pressure and water vapor environment in the mine from interfering with the electrical parts and improve the explosion-proof safety level of the lamp.

[0028] See Figure 1-3 One end of the main pipe 12 is fixedly connected to a ball head 121, which is inserted into the fixed seat 14 to form a rotatable support structure. A locking cover 13 is provided on the fixed seat 14 to lock the position of the ball head 121 and prevent the lamp body from shifting due to vibration during use. One end of the fixed seat 14 is fixedly connected to a fixing plate 141, which is fixed to the tunnel wall with screws to form a stable wall-mounted installation structure, ensuring that the lamp remains firmly installed in a high-impact environment.

[0029] See Figure 4The inner ring of the base 2 is provided with a limiting ring 21, which is a ring structure used to limit the installation position of the lamp panel 3. The lamp panel 3 is connected to the limiting ring 21 with screws to ensure that the lamp panel 3 will not be displaced in the high vibration environment during mining operations. A heat sink 22 is fixedly connected to the outer side of the base 2. The heat sink 22 is evenly distributed around the central axis of the base 2. The heat sink 22 is provided with several longitudinally arranged heat sink ribs to enhance the heat dissipation surface area and air convection path, improve the overall heat dissipation capacity of the base, and effectively control the temperature rise level of the LED lamp panel during long-term operation.

[0030] See Figure 6 The outer side of the top cover 5 is provided with heat dissipation strips 51, which are evenly distributed around the central axis of the top cover 5. The heat dissipation strips 51 are arranged in a ring shape, which increases the heat dissipation area at the top and improves the heat dissipation efficiency of the upper part of the lamp. The top cover 5 and the lamp panel 3 form a good heat conduction path through the connecting ring 11, so that the heat generated by the LED when it is working can be quickly released through the bidirectional path of the base and the top cover, thereby achieving efficient heat dissipation of the lamp in a closed and explosion-proof structure and ensuring its stable operation.

[0031] The working principle of this utility model is as follows: This mine explosion-proof light, through its reasonable structural design, combines excellent explosion-proof performance, thermal conductivity, and impact protection capabilities, making it suitable for use in special environments such as mines that are flammable, explosive, high-temperature, high-humidity, and high-impact.

[0032] The mine explosion-proof light is reliably installed on the roadway wall via the fixing plate 141. One end of the main pipe 12 is fixed with a ball head 121, which is inserted into the fixing seat 14 to form an adjustable connection structure.

[0033] The position of the ball head 121 is locked by locking the cover 13, thereby achieving precise adjustment and fixation of the lamp body's illumination direction.

[0034] The inlet pipe 122 is connected to the main pipe 12 to form an integrated wiring channel. The cable is passed through the inlet pipe, enters the connecting ring 11 through the main pipe 12, and finally connects to the lamp panel 3 to realize the power supply of the whole lamp.

[0035] The lamp panel 3 is fixedly installed on the limiting ring 21 of the inner ring of the base 2 and is tightened with screws to ensure that the lamp panel is stable and does not shift.

[0036] The light panel 3 integrates an LED light source, which generates illumination after the power is turned on. The emitted light passes through the bottom sealing cover 41 and the protective cover 42 and then shines into the external space, meeting the lighting needs of tunnel operations.

[0037] To effectively control the internal temperature rise of the lamp, multiple structural components work together to dissipate heat: A heat dissipation plate 22 is provided on the outer side of the base 2, which is distributed at equal intervals around the central axis of the base to enhance the heat convection capability; The outer side of the top cover 5 is provided with heat dissipation strips 51, which are also distributed in a ring shape to increase the heat dissipation area at the top. The lamp panel 3 and the base 2 are in close contact. The heat generated by the LED when it is working can be directly conducted to the base and the top cover and diffused to the surrounding air through the heat sink and heat dissipation strip.

[0038] The base 2 has a protective mechanism 4 at its bottom, which includes a three-layer collaborative structure: The sealing cover 41 is made of high-strength transparent material, which encloses the lamp panel area and has the ability to prevent water, dust and gas penetration. The protective cover 42 is an external metal mesh cover with high structural strength, used to withstand possible external impacts; The heat-conducting plate 43 is positioned between the sealing cover 41 and the protective cover 42, and is wave-shaped, serving a dual function: The heat from the sealing cover 41 is conducted to the protective cover 42. The protective cover has a large surface area for heat dissipation, which can enhance the heat dissipation efficiency. The wave-like structure can undergo elastic deformation when subjected to external impact, effectively absorbing impact energy and preventing it from being directly transmitted to the internal sealing cover 41 or lamp panel 3, thereby improving the structure's impact resistance.

[0039] The protective cover 42 has multiple through slots 421, which are distributed around the central axis. During the operation of the lamp, the airflow path is enhanced by thermal convection, and hot air is guided to be discharged, thereby further improving the overall heat dissipation efficiency.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
