Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof cameras, and more specifically, to an explosion-proof camera that avoids damage to the rotating cylinder body. Background Art

[0002] In many industrial production and special operation environments, such as petrochemical, coal mine, fireworks manufacturing and other fields, there are flammable and explosive gases, vapors or dusts. This requires that the electrical equipment used has explosion-proof performance to ensure production safety. As an important monitoring device, the explosion-proof camera plays a key role in these dangerous environments, being able to monitor the on-site situation in real time and providing strong guarantee for safe production.

[0003] In the industrial site, the equipment may be affected by vibrations generated from surrounding mechanical operations, material handling, etc., or accidental collision impacts. For example, in a coal mine underground, the strong vibrations generated by frequently operating coal shearers, transportation equipment, etc., and the rock falls that may occur in the roadway will impact the explosion-proof camera.

[0004] The existing explosion-proof cameras achieve explosion protection through their own camera bodies. Therefore, they can only ensure that the internal components will not be destroyed in the event of an explosion. However, the impact force of a rock fall hitting the camera will be transmitted through the camera to the inside, causing an impact on the internal components of the camera under the influence of the impact force. At the same time, in explosion-proof application scenarios such as coal mines, there are flammable and explosive gases or dusts in the environment. When the temperature inside the camera is too high, a relatively high pressure may be generated inside the equipment. If the heat dissipation holes of the camera are open at this time, the internal hot air flow may carry sparks or high-temperature particles and spray out, posing a risk of explosion when encountering external flammable and explosive substances. In addition, the mine environment contains more dust, and the accumulation of dust will affect the clarity and color restoration of the captured images, making it inconvenient to provide accurate information for the operators. Summary of the Invention

[0005] The purpose of the present invention is to provide an explosion-proof camera that avoids damage to the rotating cylinder body to solve the problems raised in the above background art.

One adjacent end of the two bases is fixedly connected with a camera body. A cylinder body is arranged inside the camera body. One end of the two bases away from each other is respectively provided with a mounting seat and a lens. The mounting seat is used to adjust the rotation angle of the camera body. Heat dissipation holes are opened on both sides of the camera body. A filter screen is arranged on one side of the heat dissipation holes. A buffer device is arranged outside the camera body. An explosion-proof device is arranged inside the camera body. A cleaning device is arranged outside the lens. When the upper side of the camera body is impacted by falling rocks, the buffer device buffers the impact force of the falling rocks and shakes off the dust attached to the filter screen while buffering; When the temperature inside the camera body is relatively high, the explosion-proof device operates to close the heat dissipation holes, forming a sealed space inside the camera body. While closing, the heat dissipation holes scrape off the dust attached to the inner wall of the camera body; when the explosion-proof device operates, it drives the cleaning device to work, and the cleaning device cleans the dust on the lens.

[0007] As a further improvement of this technical solution, the buffer device includes a protective plate arranged on the upper side of the camera body. There are two moving blocks arranged on the lower side of the protective plate. A plurality of telescopic rods are fixedly connected between the upper sides of the two moving blocks and the inner wall of the protective plate. A plurality of compression springs are fixedly connected between the upper sides of the moving blocks and the inside of the protective plate, and the compression springs are sleeved on the telescopic rods.

[0008] As a further improvement of this technical solution, the explosion-proof device includes a plurality of louvers rotatably connected inside the lens. The plurality of louvers are inclined and arranged on one side of the filter screen. Two second chutes are opened inside the base. Two sliders are slidably connected inside the two second chutes. A push plate is fixedly connected to the adjacent sides of the two sliders, and the outer wall of the push plate is in contact with the inner wall of the camera body.

[0009] As a further improvement of this technical solution, the cleaning device includes a rotating rod rotatably connected to one side of the base. The other end of the rotating rod is rotatably connected to a connecting rod. One side of the lens is rotatably connected to a cleaning rod. One side of the cleaning rod is in contact with one side of the lens, and one side of the cleaning rod is rotatably connected to the other end of the connecting rod.

[0010] As a further improvement of this technical solution, one end of each of the two adjacent bases is provided with a first chute. Two sliding plates are slidably connected inside the first chute. The adjacent sides of the two sliding plates are in contact with both sides of the moving block.

[0011] As a further improvement of this technical solution, two connecting plates are fixedly connected to the opposite sides of the two sliding plates. A plurality of bumps are fixedly connected to the inner walls of the two connecting plates, and the outer surfaces of the bumps are in contact with the surface of the filter screen.

[0012] As a further improvement of this technical solution, two first electromagnets are fixedly connected to one end of the push plate. The two first electromagnets are respectively arranged on both sides of the push plate, and the two first electromagnets are fixedly connected to the slider.

[0013] As a further improvement of the technical solution, a telescopic spring is fixedly connected to the inner wall of the No. 2 slide groove and one side of the slider, a No. 2 electromagnet is fixedly connected to the upper side of the inner wall of the camera body, and a temperature sensor is fixedly connected inside the camera body.

[0014] As a further improvement of the present technical solution, the base is internally rotatably connected to a rotating shaft, one end of the rotating shaft is fixedly connected to a gear, the other end of the rotating shaft is fixedly connected to a rotating rod, the end of the slider away from the temperature sensor is fixedly connected to a rack, and the rack is meshingly connected to the gear.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the explosion-proof camera for preventing the rotating cylinder from being damaged, a protective plate is arranged above the camera body, and the elastic deformation of multiple extrusion springs absorbs the impact energy of falling rocks falling on the protective plate, thereby increasing the protection effect of the cylinder inside the camera body. The falling rocks hit the protective plate to drive the moving block to move downward, and the moving block drives multiple protrusions on the inner wall of the connecting plate to continuously collide with the filter, shaking off the dust attached to the filter, thereby improving the heat dissipation efficiency inside the camera body and preventing dust accumulation from clogging the heat dissipation holes and affecting the performance of electronic components and the normal operation of the cylinder.

[0016] 2. In the explosion-proof camera that avoids damage to the rotating cylinder, the temperature inside the camera body is monitored in real time by a temperature sensor. When the temperature rises, the No. 1 electromagnet is powered off and loses its magnetism. Under the reaction force of the telescopic spring, the slider drives the push plate to move synchronously. When the push plate moves, the dust attached to the inner wall of the camera body is scraped off. At the same time, the movement of the push plate drives multiple louvers to rotate, which overlap in turn to close the heat dissipation holes, so that a sealed space is formed inside the camera body to prevent the internal temperature of the camera body from being too high, which may cause a high pressure inside the equipment and cause an explosion risk, thereby maintaining the safety of the explosion-proof environment and extending the service life of the equipment.

[0017] 3. In the explosion-proof camera that avoids damage to the rotating cylinder, the push plate drives the rack and the gear to mesh when moving, the gear drives the rotating rod to rotate, and the rotating rod drives the cleaning rod to swing through the connecting rod. The cleaning rod swings to clean the dust attached to the lens, and the dust on the lens is removed in time to avoid dust accumulation affecting the clarity and color reproduction of the shooting picture, which can ensure that the camera always provides a clear monitoring picture and provide accurate information for the operator.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Please refer to Figures 1 - 5 As shown, the purpose of this embodiment is to provide an explosion-proof camera that avoids damage to the rotating cylinder body, including two bases 1. One adjacent end of the two bases 1 is fixedly connected with a camera body 11. A cylinder body is arranged inside the camera body 11. One end of the two bases 1 away from each other is respectively provided with a mounting seat 12 and a lens 13. The mounting seat 12 is used to adjust the rotation angle of the camera body 11. The base 1 is installed at a suitable position through the mounting seat 12, and the angle of the camera body 11 is adjusted. Heat dissipation holes 14 are opened on both sides of the camera body 11. A filter screen is arranged on one side of the heat dissipation holes 14. Since the cylinder body inside the camera body 11 generates a relatively high temperature during operation, the two heat dissipation holes 14 provided dissipate heat from the inside of the camera body 11, and the filter screen prevents dust from entering the inside of the camera body 11 through the heat dissipation holes 14. A buffer device 2 is arranged outside the camera body 11, an explosion-proof device 3 is arranged inside the camera body 11, and a cleaning device 4 is arranged outside the lens 13; When the upper side of the camera body 11 is impacted by a falling rock, the buffer device 2 buffers the impact force of the falling rock and shakes off the dust attached to the filter screen while buffering; When the temperature inside the camera body 11 is relatively high, the explosion-proof device 3 operates to close the heat dissipation holes 14, so that a sealed space is formed inside the camera body 11. The heat dissipation holes 14 scrape off the dust attached to the inner wall of the camera body 11 while closing; when the explosion-proof device 3 operates, it drives the cleaning device 4 to work, and the cleaning device 4 cleans the dust on the lens 13.

[0023] Please refer to Figure 2 and Figure 3As shown in the figure, the buffer device 2 includes a protective plate 21 arranged on the upper side of the camera body 11. There are two moving blocks 24 arranged on the lower side of the protective plate 21. A plurality of telescopic rods 22 are fixedly connected between the upper sides of the two moving blocks 24 and the inner wall of the protective plate 21. A plurality of compression springs 23 are fixedly connected between the upper sides of the moving blocks 24 and the inside of the protective plate 21, and the compression springs 23 are sleeved on the telescopic rods 22. When using this device, when a falling rock appears in the mine tunnel, the falling rock first contacts the side wall of the protective plate 21, and the protective plate 21 will block the falling rock outside the camera body 11. By providing the protective plate 21, the protection effect on the cylinder body is increased, and the situation that the falling rock falls on the side wall of the camera body 11 and causes damage is reduced. When the falling rock lands on the protective plate 21, the falling rock impacts the protective plate 21, and the protective plate 21 moves downward and compresses a plurality of compression springs 23. The impact energy of the falling rock is absorbed and dispersed through the elastic deformation of the plurality of compression springs 23 themselves, which greatly reduces the impact force transmitted to the camera body 11, effectively preventing the camera body 11 from cracking due to direct impact, loosening or damage of internal components. Especially for the key and relatively fragile rotating cylinder body, it can avoid deformation due to severe impact and ensure that its normal rotating function is not affected.

[0024] Please refer to Figure 4 And Figure 5 As shown in the figure, one end of each of the two adjacent bases 1 is provided with a first chute 25. Two sliding plates 26 are slidably connected inside the first chute 25. The adjacent sides of the two sliding plates 26 are in contact with both sides of the moving block 24. Two connecting plates 27 are fixedly connected to the opposite sides of the two sliding plates 26. A plurality of convex blocks 28 are fixedly connected to the inner walls of the two connecting plates 27. The outer surfaces of the convex blocks 28 are in contact with the surface of the filter screen. When the protective plate 21 moves, it drives the moving block 24 to move downward. When the moving block 24 moves, it drives the two sliding plates 26 to move to both sides inside the first chute 25. When the sliding plates 26 move, they drive the connecting plates 27 to move synchronously. When the connecting plates 27 move, they drive a plurality of convex blocks 28 on the inner walls to contact the filter screen on one side of the heat dissipation holes 14. Since the plurality of convex blocks 28 are arranged in a staggered manner, the convex blocks 28 constantly collide with the filter screen, causing the filter screen to vibrate and shake off the dust attached to the filter screen, improving the heat dissipation efficiency inside the camera body 11 and preventing the accumulation of dust from blocking the heat dissipation holes 14, hindering heat dissipation, resulting in an increase in the internal temperature of the camera body 11 and affecting the performance of electronic components and the normal operation of the cylinder body.

[0025] Please refer to Figures 6 - 9As shown, the explosion-proof device 3 includes a plurality of shutters 31 rotatably connected to the inside of the lens 13, the plurality of shutters 31 are tilted, and the shutters 31 are arranged on one side of the filter screen, the inner wall of the No. 2 slide groove 32 and one side of the slider 33 are fixedly connected with a telescopic spring 35, the upper side of the inner wall of the camera body 11 is fixedly connected with a No. 2 electromagnet 36, and the inside of the camera body 11 is fixedly connected with a temperature sensor 38, and the temperature sensor 38 is connected to the control circuit. When the internal temperature of the camera body 11 is too high, the temperature sensor 38 monitors the internal temperature of the camera body 11 in real time. When the temperature rises, the temperature sensor 38 converts the temperature signal into a digital electrical signal and quickly transmits it to the control circuit. After the signal receiving module of the control circuit receives the signal from the temperature sensor 38, the processing module immediately compares it with a preset temperature threshold. If the detected temperature exceeds the threshold, it indicates that the internal temperature of the camera body 11 is too high, and the control instruction output module immediately sends a low-level signal to cut off the power supply of the No. 1 electromagnet 34.

[0026] See also Figure 8 and Figure 9 As shown, the base 1 has two No. 2 slide grooves 32, the two No. 2 slide grooves 32 are slidably connected with sliders 33, and the adjacent sides of the two sliders 33 are fixedly connected with push plates 37, and the outer wall of the push plates 37 fits the inner wall of the camera body 11, and one end of the push plates 37 is fixedly connected with two No. 1 electromagnets 34, which are respectively arranged on both sides of the push plates 37, and the two No. 1 electromagnets 34 are fixedly connected with the sliders 33. After the No. 1 electromagnet 34 is powered off, it loses its magnetism, and under the reaction force of the telescopic spring 35, it drives the slider 33 to move toward the No. 2 electromagnet 36 in the No. 2 slide groove 32. Since the slider 33 is connected to the No. 1 electromagnet 34, the slider During the movement, the slider 33 drives the No. 1 electromagnet 34 to move synchronously. When the No. 1 electromagnet 34 moves to be attracted to the No. 2 electromagnet 36, the slider 33 drives the push plate 37 to move synchronously during the movement. When the push plate 37 moves, the dust attached to the inner wall of the camera body 11 is scraped off. At the same time, the movement of the push plate 37 drives multiple louvers 31 to rotate, and they are overlapped in sequence, so that the louvers 31 completely cover the heat dissipation holes 14, and the heat dissipation holes 14 are closed, so that a sealed space is formed inside the camera body 11 to prevent the camera body 11 from having a high temperature inside. When the temperature is too high, a high pressure may be generated inside the equipment, causing an explosion risk, thereby maintaining the safety of the explosion-proof environment and extending the service life of the equipment.

[0027] See also Figure 9 and Figure 10As shown in the figure, the cleaning device 4 includes a rotating rod 44 rotatably connected to one side of the base 1. The other end of the rotating rod 44 is rotatably connected to a connecting rod 45. One side of the lens 13 is rotatably connected to a cleaning rod 46. One side of the cleaning rod 46 is in contact with one side of the lens 13. One side of the cleaning rod 46 is rotatably connected to the other end of the connecting rod 45. A rotating shaft 43 is rotatably connected to the inside of the base 1. One end of the rotating shaft 43 is fixedly connected to a gear 42. The other end of the rotating shaft 43 is fixedly connected to the rotating rod 44. The end of the slider 33 away from the temperature sensor 38 is fixedly connected to a rack 41. The rack 41 is meshed with the gear 42. When the push plate 37 moves, it drives the rack 41 to move. The movement of the rack 41 drives the gear 42 to rotate. The gear 42 drives the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 drives the rotating rod 44 to rotate. The rotating rod 44 drives the connecting rod 45 to rotate. The connecting rod 45 drives the cleaning rod 46 to swing. The swinging of the cleaning rod 46 cleans the dust attached to the lens 13, timely removes the dust on the lens 13, avoids the accumulation of dust affecting the clarity and color restoration degree of the captured image, and can ensure that the camera always provides a clear monitoring image and provides accurate information for the operator.

[0028] When the explosion-proof camera of the present invention that avoids damage to the rotating cylinder is in specific use, the protection plate 21 is used to increase the protection of the camera body 11. The elastic deformation of the plurality of compression springs 23 absorbs and disperses the impact energy of the falling stones, reducing the impact force transmitted to the camera body 11. When the falling stones fall on the protection plate 21, the movement of the protection plate 21 drives the moving block 24 to move downward. When the moving block 24 moves, it drives the two sliding plates 26 to move to both sides inside the first sliding groove 25. When the sliding plates 26 move, they drive the connecting plate 27 to contact the filter screen on one side of the heat dissipation hole 14, causing the multiple bumps 28 on the inner wall of the connecting plate 27 to continuously collide with the filter screen, shaking off the dust attached to the filter screen, improving the heat dissipation efficiency inside the camera body 11, and preventing the accumulation of dust from blocking the heat dissipation hole 14, resulting in an increase in the internal temperature of the camera body 11 and affecting the performance of electronic components and the normal operation of the cylinder.

[0029] The temperature inside the camera body 11 is monitored in real time by the temperature sensor 38. When the temperature rises, the temperature sensor 38 converts the temperature signal into a digital electrical signal and quickly transmits it to the control circuit. The control circuit causes the No. 1 electromagnet 34 to be powered off and lose its magnetism. Under the reaction force of the telescopic spring 35, the slider 33 is driven to move toward the No. 2 electromagnet 36 inside the No. 2 slide groove 32. During the movement, the slider 33 drives the No. 1 electromagnet 34 to move synchronously with the No. 2 electromagnet 36 to attract each other. During the movement, the slider 33 drives the push plate 37 to move synchronously. When the push plate 37 moves, the dust attached to the inner wall of the camera body 11 is scraped off. At the same time, the push plate 37 moves and drives multiple louvers 31 to rotate, and overlap in sequence, so that the louvers 31 completely cover the heat dissipation holes 14, and the heat dissipation holes 14 are closed, so that a sealed space is formed inside the camera body 11 to prevent the internal temperature of the camera body 11 from being too high, and the internal pressure of the equipment may be high, causing the risk of explosion, thereby maintaining the safety of the explosion-proof environment and extending the service life of the equipment.

[0030] At the same time, the push plate 37 drives the rack 41 to move when it moves, and the movement of the rack 41 drives the gear 42 to rotate, and the gear 42 drives the rotating rod 44 to rotate. The rotating rod 44 drives the cleaning rod 46 to swing through the connecting rod 45. The cleaning rod 46 swings to clean the dust attached to the lens 13, and the dust on the lens 13 is removed in time to avoid dust accumulation affecting the clarity and color reproduction of the captured image, thereby ensuring that the camera always provides a clear monitoring image and provides accurate information for the operator.
