Description

Technical Field

[0001] This utility model relates to the field of safety helmet technology, and in particular to a safety helmet that combines alarm and monitoring functions. Background Technology

[0002] Safety helmets are the core protective equipment for ensuring the safety of workers' heads. As the complexity of the working environment increases, safety helmets with only basic protective functions can no longer meet the needs. Workers need to monitor the working area in real time (such as equipment operation details and potential hazards in the surrounding environment), and at the same time, they need to detect environmental anomalies in a timely manner (such as the leakage of harmful gases). Therefore, safety helmets with alarm and monitoring functions have gradually become important equipment for ensuring work safety.

[0003] Most existing safety helmets are only equipped with a single-function camera, which cannot be used to switch between different cameras as needed according to the work scenario (such as panoramic observation during the day, night vision at night, and detailed work observation). At the same time, in order to protect the camera, existing products mostly have a fixed protective plate on the top of the camera. Therefore, it is not convenient to remove the camera located under the protective plate during maintenance. Therefore, we have released a safety helmet with alarm and monitoring functions to meet people's needs. Utility Model Content

[0004] The purpose of this application is to provide a safety helmet that combines alarm and monitoring functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a safety helmet with both alarm and monitoring functions, comprising a safety helmet body, a controller and an air monitor fixedly installed on the left side of the safety helmet body, a speaker fixedly installed on the right side of the safety helmet body, an arc-shaped plate fixedly installed on the front side of the safety helmet body, and an infrared camera, an ultra-wide-angle camera and a macro camera arranged below the arc-shaped plate, wherein the infrared camera and the macro camera are symmetrically arranged based on the ultra-wide-angle camera;

[0006] The top of the arc-shaped plate is provided with a rotating hole, and a hollow column is rotatably installed in the rotating hole. The sides of the infrared camera, ultra-wide-angle camera and macro camera are all detachably equipped with mounting plates, and the three mounting plates are slidably connected to the hollow column.

[0007] A moving mechanism is installed on the rotating hole, which is used to move the infrared camera, the ultra-wide-angle camera and the macro camera.

[0008] The hollow column is equipped with a fixing structure on its side, and the top of the arc plate is fixedly installed with an arc rod. The side of the arc rod is provided with three fixing slots, which are respectively set to correspond to the infrared camera, the ultra-wide-angle camera and the macro camera. The fixing mechanism is installed in cooperation with one of the fixing slots.

[0009] Preferably, the fixing mechanism includes a fixing sleeve fixedly installed on the outer side of the hollow column, a fixing rod slidably installed inside the fixing sleeve, one end of the fixing rod extending into one of the fixing grooves, a toggle plate fixedly sleeved on the fixing rod, and a spring sleeved on the fixing rod, with both ends of the spring respectively fixedly installed on the sides of the fixing sleeve and the toggle plate that are close to each other.

[0010] Preferably, the moving mechanism includes a screw, the bottom end of which is rotatably mounted on the bottom inner wall of the hollow column. A threaded sleeve is threaded onto the screw, and three push rods are rotatably mounted on the side of the threaded sleeve. The ends of the three push rods away from the circular shaft are respectively rotatably mounted on the sides of the three mounting plates.

[0011] Preferably, the hollow column has three clearance holes on its inner wall, and one end of each of the three push rods passes through the three clearance holes.

[0012] Preferably, a circular hole is provided on the inner wall of the top side of the hollow column, and a circular shaft is rotatably installed in the circular hole, with the bottom end of the circular shaft being fixedly connected to the top end of the screw.

[0013] Preferably, a knob is fixedly installed at the top end of the circular shaft.

[0014] Preferably, each of the three mounting plates is fixedly mounted with a sliding rod on its side, and each of the three sliding rods is slidably fitted with a sliding sleeve. The ends of the three sliding sleeves away from the mounting plates are fixedly mounted on the outer side of the hollow column.

[0015] Preferably, a battery is fixedly installed on the rear side of the helmet body, and the speaker and controller are connected to the controller.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] When switching between multiple cameras, this application only requires moving the toggle plate of the fixing mechanism to disengage the fixing rod from the fixing groove of the arc rod. Rotating the hollow column allows the infrared camera, ultra-wide-angle camera, and macro camera to be switched to the working position as needed. After switching, the spring returns to its original position, causing the fixing rod to engage with the corresponding fixing groove for precise positioning. This allows for flexible adaptation to different scenarios such as panoramic observation, night vision, and fine operations. When maintaining the camera, rotating the knob rotates the round shaft and screw, causing the threaded sleeve to move downwards and push the push rod to move the mounting plate, thus moving the camera out from under the arc plate. This eliminates the need to disassemble the entire structure, making the operation convenient and efficient. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1 - Figure 6 The embodiments provided by this utility model are as follows:

[0028] The safety helmet, which combines alarm and monitoring functions, includes a helmet body 1. A controller 3 and an air monitor 4 are fixedly installed on the left side of the helmet body 1. A speaker 6 is fixedly installed on the right side of the helmet body 1. An arc-shaped plate 2 is fixedly installed on the front side of the helmet body 1. An infrared camera 8, an ultra-wide-angle camera 9, and a macro camera 10 are located below the arc-shaped plate 2. The infrared camera 8 and the macro camera 10 are symmetrically arranged based on the ultra-wide-angle camera 9. Through the arrangement of the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10, the ultra-wide-angle camera 9 can be used to view the panoramic view when outdoors during the day. When entering a dark area, the infrared camera 8 can be switched to view heat sources and object outlines. When performing fine work, the macro camera 10 can be switched to view details.

[0029] The top of the arc plate 2 is provided with a rotating hole 14, and a hollow column 13 is rotatably installed in the rotating hole 14. The sides of the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10 are all detachably equipped with mounting plates 15, and the three mounting plates 15 are slidably connected to the hollow column 13.

[0030] A moving mechanism is installed on the rotating hole 14. The moving mechanism is used to move the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, the moving mechanism includes a screw 12, the bottom end of which is rotatably mounted on the inner wall of the bottom side of the hollow column 13. A threaded sleeve 26 is threaded onto the screw 12, and three push rods 7 are rotatably mounted on the side of the threaded sleeve 26. The ends of the three push rods 7 away from the round shaft 25 are respectively rotatably mounted on the sides of three mounting plates 15. When maintenance is required on the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10, the knob 24 can be rotated. The rotation of the knob 24 drives the round shaft 25 and the screw 12 to rotate. The rotation of the screw 12 drives the threaded sleeve 26 to move downward. The movement of the threaded sleeve 26 drives the three push rods 7 to rotate. The rotation of the three push rods 7 drives the three mounting plates 15 away from the hollow column 13, thereby moving the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10 out of the area below the arc plate 2, facilitating maintenance of the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10.

[0032] A fixing structure is installed on the side of the hollow column 13, and an arc rod 23 is fixedly installed on the top of the arc plate 2. Three fixing slots 19 are opened on the side of the arc rod 23. The three fixing slots 19 are respectively set to correspond to the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10. The fixing mechanism is installed in conjunction with one of the fixing slots 19.

[0033] like Figure 5As shown, the fixing mechanism includes a fixing sleeve 18 fixedly installed on the outer side of the hollow column 13, a fixing rod 21 slidably installed inside the fixing sleeve 18, one end of the fixing rod 21 extending into one of the fixing grooves 19, a toggle plate 22 fixedly sleeved on the fixing rod 21, and a spring 20 sleeved on the fixing rod 21. The two ends of the spring 20 are respectively fixedly installed on the sides of the fixing sleeve 18 and the toggle plate 22 that are close to each other. During switching, the fixed rod 21 can be moved out of the fixed groove 19 by moving the toggle plate 22. At this time, the spring 20 is compressed. The toggle plate 22 can be rotated to make the hollow column 13 rotate. The rotation of the hollow column 13 drives the three sliding sleeves 17, the three sliding rods 16 and the three mounting plates 15 to rotate, thereby causing the infrared camera 8, the ultra-wide-angle camera 9 and the macro camera 10 to rotate. This allows switching to be performed according to the working conditions. After switching, the infrared camera 8 or the macro camera 10 can be adjusted to the middle position. At this time, the fixed rod 21 corresponds to the position of the other fixed groove 19. Under the action of the spring 20, the fixed rod 21 enters the fixed groove 19 to complete the limit.

[0034] like Figure 3 As shown, three clearance holes 11 are provided on the inner wall of the hollow column 13, and one end of each of the three push rods 7 passes through the three clearance holes 11. The clearance holes 11 are provided to allow the push rods 7 to pass through, thus not affecting the rotation of the push rods 7.

[0035] like Figure 6 As shown, a circular hole is provided on the inner wall of the top side of the hollow column 13. A circular shaft 25 is rotatably installed in the circular hole, and the bottom end of the circular shaft 25 is fixedly connected to the top end of the screw 12. A knob 24 is fixedly installed on the top end of the circular shaft 25. The knob facilitates the rotation of the circular shaft 25, which in turn allows the screw 12 to be rotated.

[0036] like Figure 4 As shown, each of the three mounting plates 15 has a sliding rod 16 fixedly mounted on its side, and each of the three sliding rods 16 has a sliding sleeve 17 slidably fitted onto it. The ends of the three sliding sleeves 17 furthest from the mounting plate 15 are fixedly mounted on the outer side of the hollow column 13. The sliding sleeves 17 and the sliding rods 16 ensure that the mounting plate 15 can only slide along the direction of the sliding sleeves 17.

[0037] like Figure 1 and Figure 2 As shown, a battery 5 is fixedly installed on the rear side of the helmet body 1, and a speaker 6, an air monitor 4, and a controller 3 are connected. The battery 5 provides power, and the air monitor 4 monitors the environment. If an abnormality occurs, it transmits a signal to the controller 3, causing the speaker 6 to sound an alarm.

[0038] Working principle:

[0039] During use, the air monitor 4 can monitor the environment. If an abnormality occurs, it transmits a signal to the controller 3, causing the speaker 6 to sound an alarm. With the infrared camera 8, ultra-wide-angle camera 9, and macro camera 10 configured, the ultra-wide-angle camera 9 can be used for panoramic views outdoors during the day. When entering dark areas, the infrared camera 8 is switched to view heat sources and object outlines. For detailed work, the macro camera 10 can be switched to view details. Switching between these modes is achieved by moving the toggle plate 22, which moves the fixing rod 21 out of the fixing slot 19. At this time, the spring... When compression occurs, the toggle plate 22 can be rotated to make the hollow column 13 rotate. The rotation of the hollow column 13 drives the three sliding sleeves 17, the three sliding rods 16 and the three mounting plates 15 to rotate, thereby causing the infrared camera 8, the ultra-wide-angle camera 9 and the macro camera 10 to rotate. This allows for switching according to the working conditions. After switching, the infrared camera 8 or the macro camera 10 can be adjusted to the middle position. At this time, the position of the fixing rod 21 corresponds to that of another fixing groove 19. Under the action of the spring 20, the fixing rod 21 enters the fixing groove 19 to complete the limit.

[0040] When maintenance is required on the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10, the knob 24 can be rotated. The rotation of the knob 24 causes the round shaft 25 and the screw 12 to rotate. The rotation of the screw 12 causes the threaded sleeve 26 to move downward. The movement of the threaded sleeve 26 causes the three push rods 7 to rotate. The rotation of the three push rods 7 causes the three mounting plates 15 to move away from the hollow column 13, thereby moving the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10 out of the arc plate 2, making it easier to maintain the infrared camera 8, the ultra-wide-angle camera 9, and the macro camera 10.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
