[0001] The present invention relates to the technical field of law enforcement recorders, and particularly to a patrol alarm system for a 5G law enforcement recorder. Background Art

[0002] In construction engineering projects, there are a large number of hazard sources with a wide coverage. The existing methods for identifying hazard sources mainly rely on manual inspections, which have the risk of being easily overlooked. The on-site operators and the personnel conducting risk inspections themselves cannot individually cope with multi-angle potential risks, and some risk points and hazard sources are difficult to detect in advance, and the personnel cannot react in advance, making it impossible for the personnel to prevent sudden or impending dangers and disasters in a timely manner.

[0003] At the present stage, the equipment used for risk and hidden danger inspections are all numerical evaluations, which have disadvantages such as single function, low portability, and low data processing efficiency. In addition, during long-term use, the shooting module of the law enforcement recorder may be damaged due to accidents such as external collisions. When the shooting module is damaged and needs to be repaired or replaced, it is very inconvenient. In view of the above problems, the inventor proposes a patrol alarm system for a 5G law enforcement recorder to solve the above problems. Summary of the Invention

[0004] In order to solve the problems that the existing law enforcement recorders have disadvantages such as single function, low portability, and low data processing efficiency, and during long-term use, the shooting module of the law enforcement recorder may be damaged due to accidents such as external collisions, and it is very inconvenient when the shooting module is damaged and needs to be repaired or replaced; the purpose of the present invention is to provide a patrol alarm system for a 5G law enforcement recorder.

The lithium battery arranged inside the battery protection cover is used to supply energy to the body of the law enforcement recorder. The anti-slip pattern arranged on the back of the battery protection cover can prevent the staff from easily slipping when holding the body of the law enforcement recorder. When it is necessary to clamp the body of the law enforcement recorder on the collar or the upper pocket of the coat, loosen the fastening knob to separate the rod end of the fastening knob from the clamping rod, then pull out the clamping rod downward, and then reverse-twist the fastening knob to make the rod end of the fastening knob closely fit with the clamping rod, so as to limit and fix the pulled-out clamping rod. There is a distance between the clamping rod and the housing. Clamp the clamping rod on the collar or the upper pocket of the coat, so that the collar or the upper pocket of the coat is located in the gap between the clamping rod and the housing, and the clamping operation can be completed. When the clamping is not required, or when it is necessary to view the display screen, the clamping rod can be retracted into the convex plate to avoid affecting the viewing of the display screen. An emergency button, a first function button and a second function button are arranged on the side wall of the housing.

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.

[0029] Embodiment: As Figures 1-7 shown, the present invention provides a patrol alarm system for a 5G law enforcement recorder, including a main body 1 of the law enforcement recorder. The main body 1 of the law enforcement recorder includes a 5G communication module, a shooting module 109, a display module, a laser ranging module, and a GPS positioning module;

[0030] The 5G communication module is used to send patrol data and environmental data to the cloud storage platform through the 5G network. The cloud storage platform is used to store the patrol data and environmental data, and forward the patrol data and environmental data to the information processing terminal;

[0036] By adopting the above technical solution, the lithium battery arranged inside the battery protection cover 106 is used to supply energy to the main body 1 of the law enforcement recorder. The anti-slip pattern 107 arranged on the back of the battery protection cover 106 can prevent the staff from easily slipping when holding the main body 1 of the law enforcement recorder. When it is necessary to clip the main body 1 of the law enforcement recorder to the collar or the upper pocket of the coat, loosen the fastening knob 113 to separate the rod end of the fastening knob 113 from the clamping rod 112. Then pull out the clamping rod 112 downward, and then reverse the fastening knob 113 to make the rod end of the fastening knob 113 closely fit the clamping rod 112, so as to limit and fix the pulled-out clamping rod 112. There is a distance between the clamping rod 112 and the housing 101. Clip the clamping rod 112 to the collar or the upper pocket of the coat, so that the collar or the upper pocket of the coat is located in the gap between the clamping rod 112 and the housing 101, and the clamping operation can be completed. When the clamping is not required, or when it is necessary to view the display screen 102, the clamping rod 112 can be retracted into the convex plate 111 to avoid the clamping rod 112 affecting the viewing of the display screen 102. An emergency button 103, a first function button 104 and a second function button 105 are arranged on the side wall of the housing 101.

[0037] A notch 2 is arranged on the upper part of the side wall of the housing 101. The notch 2 is located above the battery protection cover 106.

Fastening screws 110 are inserted and threaded at the four corners of the side wall of the protective shell 108. The protective shell 108 is fixedly connected to the side wall of the housing 101 through the fastening screws 110. A convex shell 114 is fixedly connected to the side of the protective shell 108 facing the housing 101. The components of the shooting module 109 are located inside the convex shell 114. Card slots 115 are arranged on both sides of the convex shell 114.

[0038] By adopting the above technical solution, unscrewing the fastening screw 110 can separate the protective shell 108 from the shell 101, and the convex shell 114 is used to protect the components of the shooting module 109.

[0039] The clamping assembly 3 includes a rotating shaft 301. The rotating shaft 301 is located inside the shell 101 and is rotatably connected to the shell 101. One end of the rotating shaft 301 is provided with a hexagonal groove 302, and the other end of the rotating shaft 301 is fixedly connected to a worm 303. The worm 303 is located inside the shell 101, and an end cover 4 is detachably arranged on the side wall of the shell 101, and the end cover 4 corresponds to the hexagonal groove 302.

[0040] By adopting the above technical solution, when the shooting module 109 is damaged and needs to be replaced or repaired, the end cover 4 is opened, and an external tool is matched with the hexagonal groove 302, and the external tool is screwed to make the rotating shaft 301 rotate. The worm 303 meshes with the worm gear 304 under the action of the rotating shaft 301.

[0041] A worm gear 304 is meshed on the side wall of the worm 303. A first transmission shaft 305 is fixedly connected through the middle of the side wall of the worm gear 304. A first bevel gear 306 is fixedly connected to the end of the first transmission shaft 305 far from the worm gear 304. A bearing seat 307 is rotatably sleeved on the side wall of the first transmission shaft 305, and the side wall of the bearing seat 307 is fixedly connected to the inner wall of the shell 101.

One end of the second transmission shaft 309 is rotatably connected to the shell 101, and a transmission gear 310 is fixedly connected to the other end of the second transmission shaft 309. A rack 311 is meshed on the side wall of the transmission gear 310. The number of the racks 311 is two, and the two racks 311 correspond to each other. A connecting plate 312 is fixedly connected to the side of the rack 311 facing away from the transmission gear 310. A slide rail 313 is fixedly connected to the side of the connecting plate 312 facing away from the rack 311. A guide plate 314 is arranged on the side of the connecting plate 312 facing away from the rack 311. A guide groove is arranged on the side of the guide plate 314 facing the slide rail 313, and the guide groove is slidably connected to the slide rail 313.

[0042] By adopting the above technical solution, the mutual meshing of the worm 303 and the worm wheel 304 enables the first transmission shaft 305 to drive the first bevel gear 306 to rotate. The mutual meshing of the first bevel gear 306 and the second bevel gear 308 enables the second transmission shaft 309 to drive the transmission gear 310 to rotate. Through the mutual meshing of the transmission gear 310 and the toothed plate 311, and in cooperation with the slide rail 313 and the guiding groove, the two toothed plates 311 can move relatively or in opposite directions. Furthermore, under the action of the connecting rod 316, the clamping plates 317 can move relatively or in opposite directions, and then the clamping rods 318 can be engaged with or separated from the clamping grooves 115.

[0043] A convex block 315 is fixedly connected to the side wall of the toothed plate 311. A connecting rod 316 is fixedly connected to the top surface of the convex block 315 in an inserted manner. One end of the connecting rod 316 away from the convex block 315 is fixedly connected to a clamping plate 317. A clamping rod 318 is fixedly connected to the side wall of the clamping plate 317. The clamping rod 318 corresponds to and cooperates with the clamping groove 115.

[0044] By adopting the above technical solution, when the clamping rod 318 is engaged with the clamping groove 115, the convex shell 114 can be limited and fixed at this time, and the shooting module 109 is in a non-removable state. When the clamping rod 318 is separated from the clamping groove 115, the convex shell 114 can be disassembled at this time, and then the shooting module 109 can be removed for replacement or repair.

[0045] Working principle: When the present invention is in use, when it is necessary to clamp the law enforcement recorder main body 1 on the collar or the upper pocket of the upper garment, loosen the fastening knob 113 to separate the rod end of the fastening knob 113 from the clamping rod 112. Then, pull out the clamping rod 112 downward, and then reverse the fastening knob 113 to make the rod end of the fastening knob 113 closely fit the clamping rod 112, so as to limit and fix the pulled-out clamping rod 112. There is a distance between the clamping rod 112 and the housing 101. Clamp the clamping rod 112 on the collar or the upper pocket of the upper garment, so that the collar or the upper pocket of the upper garment is located in the gap between the clamping rod 112 and the housing 101, and the clamping operation can be completed. When the clamping is not required, or when it is necessary to view the display screen 102, the clamping rod 112 can be retracted into the convex plate 111 to avoid the influence of the clamping rod 112 on the viewing of the display screen 102;

[0046] When the photographing module 109 is damaged and needs to be replaced or repaired, open the end cover 4, cooperate the external tool with the hexagonal groove 302, and turn the external tool to make the rotating shaft 301 rotate. The worm 303 meshes with the worm wheel 304 under the action of the rotating shaft 301, so that the first transmission shaft 305 drives the first bevel gear 306 to rotate. Through the mutual meshing of the first bevel gear 306 and the second bevel gear 308, the second transmission shaft 309 can drive the transmission gear 310 to rotate. Through the mutual meshing of the transmission gear 310 and the toothed plate 311, and the mutual cooperation of the slide rail 313 and the guide groove, the two toothed plates 311 can move relatively or in opposite directions. Furthermore, under the action of the connecting rod 316, the clamping plate 317 can move relatively or in opposite directions, and then the clamping rod 318 can be engaged with or separated from the clamping groove 115;

[0047] When the clamping rod 318 is engaged with the clamping groove 115, the convex shell 114 can be limited and fixed at this time, and the photographing module 109 is in a non-detachable state. When the clamping rod 318 is separated from the clamping groove 115, the convex shell 114 can be disassembled at this time, and then the photographing module 109 can be removed for replacement or repair.
