DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a video monitoring device for weak current engineering that is easy to maintain, including a pole 1, a mounting seat 2 is fixedly connected to the top of the pole 1, support plates 3 are fixedly connected to the left and right sides of the top of the mounting seat 2, a support platform 9 is fixedly connected between the middle parts of the two support plates 3, a fixed block 10 is fixedly connected to the rear edge of the top of the support platform 9, a cylinder 11 is hingedly connected to the front side of the fixed block 10, a push plate 12 is fixedly connected to the output end of the cylinder 11, and two racks 13 are fixedly connected to the front side of the push plate 12, and two gears 14 are rotatably connected to the front edge of the support platform 9, the gears 14 and the racks 13 are meshed and connected, and the tops of the two gears 14 are rotatably connected to a connecting plate 15, and the two connecting plates One end 15 is rotatably connected to a connecting plate 2 16 away from the gear 14, a film cloth roller 4 is rotatably connected between the tops of the two support plates 3, spring springs 5 are sleeved on the left and right ends of the film cloth roller 4, a film cloth 7 is arranged on the front side of the film cloth roller 4, a fixing plate 8 is fixedly connected to the front side of the bottom of the film cloth 7, the fixing plate 8 is fixedly connected to the top of the connecting plate 2 16, a fixing component is arranged inside the mounting seat 2, a monitor 23 is fixedly connected to the top of the fixing component, the outer sides of the two support plates 3 are fixedly connected to a fixing seat 6, the bottom of the vertical pole 1 is fixedly connected to a base 24, the bottom of the push plate 12 is slidably connected to the top of the support platform 9, one end of the spring spring 5 is fixedly connected to the outer wall of the support plate 3, and the other end of the spring spring 5 is fixedly connected to the side end of the film cloth roller 4.
[0031] Specifically, when the weather changes suddenly and heavy rain pours down, in order to ensure that the monitor 23 can work normally and maintain the clarity of its video, the start cylinder 11 begins to push the push plate 11 forward. Since the push plate 11 and the rack 13 are fixedly connected, the rack 13 will also move synchronously. The rack 13 and the gear 14 are meshingly connected. When the rack 13 moves forward, it will drive the gear 14 to rotate. The rotation of the gear 14 will further drive the connection plate 1 15 and the connection plate 2 16 to rotate. With the cooperation of the spring 5, when the connection plate rotates to a specific position, the membrane cloth 7 will be unfolded and hung in front of the monitor 23. In this way, the membrane cloth 7 is like a temporary awning, which can effectively block the rainstorm and ensure that the monitor 23 will not be wetted by rain, thereby maintaining the clarity of its video recording. When the weather is clear and the sun is shining, in order to protect the membrane cloth 7 from long-term sun exposure and wind and rain, it needs to be retracted, and the cylinder 11 is started to push the push plate 12 backward to reset it to the initial position. The reset of the push plate 12 drives the rack 13 to move backward. Due to the meshing connection between the rack 13 and the gear 14, the movement of the rack 13 will drive the gear 14 to rotate in the opposite direction, and the rotation of the gear 14 will then drive the connection plate 1 15 and the connection plate 2 16 to rotate in the opposite direction. At the same time, the spring 5 will also play a role. Under the pulling force of the clockwork spring 5, the film cloth roller 4 will start to rotate. As the film cloth roller 4 rotates, the originally unfolded film cloth 7 will gradually be rolled back onto the film cloth roller 4, thereby completing its retrieval work.
[0032] Reference Figure 1 and Figure 4 The fixing component includes a shell 17, the outside of the shell 17 is slidably connected to the front side of the mounting seat 2, two card slots 18 are provided inside the shell 17, and multiple springs 19 are fixedly connected inside the two card slots 18. The spring 19 is fixedly connected to a baffle 20 near one end of the shell 17, a pull rod 21 is fixedly connected to the top of the baffle 20, and a limit block 22 is fixedly connected to the bottom of the baffle 20. The baffle 20 is slidably connected to the inside of the card slot 18, the pull rod 21 passes through the shell 17 and is slidably connected to the inside of the mounting seat 2, and the limit block 22 passes through the shell 17 and is plugged into the inside of the shell 17.
[0033] Specifically, when the monitor 23 needs to be maintained or replaced, the staff will first push the pull rod 23 inwards. Since the pull rod 23 and the baffle 20 are connected together, the baffle 20 will move inwards synchronously. In this process, the baffle 20 will squeeze the spring 19 next to it, causing it to be compressed. The pull rod 23 will continue to be pushed until the limit block 22 is completely separated from the inside of the mounting seat 2. At this time, the staff can easily take the monitor 23 out of the mounting seat 2 for subsequent maintenance work. When the maintenance is completed and the monitor 23 needs to be reinstalled in place, the staff will first put the housing 17 into the card slot inside the mounting seat 2, and then pull the pull rod 21 outwards. Since the pull rod 21 and the baffle 20 are connected together, the baffle 20 will move outwards synchronously. As the baffle 20 moves, the previously compressed spring 19 will gradually reset and return to its original state until the limit block 22 is inserted into the inside of the mounting seat 2 to complete its installation and disassembly.
[0034] Working principle: When encountering heavy rain, in order to ensure the clarity of the surveillance video of the monitor 23, the cylinder 11 is started at this time, pushing the push plate 11 to move forward, driving the rack 13 to move synchronously, and due to the meshing connection between the gear 14 and the rack 13, the rack 13 will drive the gear 14 to rotate in the process of moving forward, and the rotation of the gear 14 will drive the connecting plate 15 to rotate, and then drive the connecting plate 2 16 to rotate. At this time, with the cooperation of the clockwork spring 5, the membrane cloth 7 is unfolded to shield the monitor 23 from rain. When the weather is clear, the membrane cloth 7 needs to be retracted, and the cylinder 11 is started to drive the push plate 12 to reset, and then drive the rack 13 to move backward. Due to the meshing connection between the gear 14 and the rack 13, the rack 13 The movement will also drive the gear 14 to rotate, and the rotation of the gear 14 will drive the connecting plate 15 and the connecting plate 16 to rotate, and at the same time, under the action of the clockwork spring 5, the membrane cloth roller 4 will be driven to rotate, so that the membrane cloth 4 is rolled back to the membrane cloth roller 4 to complete its retraction. When the monitor 23 needs to be maintained, the pull rod 23 is pushed inward to drive the baffle 20 to move synchronously, thereby squeezing the spring 19 until the limit block 22 is disengaged from the inside of the mounting seat 2. At this time, the monitor 23 can be taken out. When it needs to be installed, the outer shell 17 is placed in the card slot inside the mounting seat, and the pull rod 21 is pulled outward to drive the baffle 20 to move synchronously, thereby resetting the spring 19 until the limit block 22 is tightly inserted into the inside of the mounting seat 2 to complete its installation and disassembly.
