Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and more specifically, to a construction site monitoring device. Background Technology

[0002] BIM modeling refers to creating a virtual building in a computer using digital means. This virtual building not only contains visual information about its geometric shape but also a wealth of non-geometric information, such as the fire resistance rating of materials, heat transfer coefficients, component costs, and procurement information. The BIM model is used throughout the entire project lifecycle, providing detailed data support from design to construction to operation and maintenance.

[0003] Construction sites are typically equipped with surveillance cameras. These cameras capture and transmit images, allowing personnel to intuitively understand the construction progress. Additionally, various construction materials are stored at the site, and personnel can also observe the situation through the cameras. If theft of materials is discovered, it is easier to gather evidence.

[0004] Currently, some existing monitoring cameras used for real-time BIM construction sites are stored away after a construction project is completed. Over time, the protective boxes used to protect the monitoring cameras may be lost during transport. Without protective boxes, the monitoring cameras may be damaged during each transfer. Therefore, we provide a construction site monitoring device. Utility Model Content

[0005] The purpose of this utility model is to provide a construction site monitoring device to solve the problems mentioned in the background art above:

[0006] Currently, some existing surveillance cameras used for real-time BIM construction sites are stored away after a construction project is completed. Over time, the protective boxes used to protect the surveillance cameras may be lost during the transfer. Without the protective boxes, the surveillance cameras may be damaged by bumps and knocks each time they are moved.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A construction site monitoring device includes a base plate. Four frames are fixedly connected to the top of the base plate and are symmetrically distributed. Slider blocks are slidably connected to the inner sides of the frames. A rotating rod is rotatably connected between adjacent sliders. A side plate is fitted over the rotating rod. The side plate and base plate protect the monitoring camera, and the side plate, when unfolded, can act as a support for the monitoring camera. The side plate is fixedly connected to the rotating rod. A fixed plate is fixedly connected to the top of the base plate. A movable seat is fitted over the fixed plate and slidably connected to the fixed plate. A monitoring camera is rotatably connected to the inner side of the movable seat.

[0009] Preferably, the rotating rod passes vertically through the slider and extends into the interior of the slider. Both ends of the rotating rod are fixedly connected with bevel gears. Two adjacent bevel gears mesh with each other. Under the action of the bevel gears, when one of the four side plates is rotated and unfolded, the other three will unfold at the same time. In this way, the user only needs to operate one side plate.

[0010] Preferably, a top cover is rotatably connected to the outside of the frame, and a first magnetic sheet is fixedly connected to the outside of the top cover near the frame. A first iron sheet is fixedly connected to the top of the frame. The first iron sheet and the first magnetic sheet are used in conjunction. A slot is provided on one side of one of the side panels. The slot is used in conjunction with the top cover. When the side panel is unfolded, the top cover can be inserted into the slot to limit the position of the unfolded side panel.

[0011] Preferably, a second magnetic sheet is fixedly connected to the bottom of the side plate and below the slot, and a second iron sheet is fixedly connected to the top of the base plate. The second iron sheet and the second magnetic sheet are used together to define the position of the side plate.

[0012] Preferably, the cross-sections of the frame and the slider are both L-shaped structures, the outer wall of the slider is fitted with the inner wall of the frame, and the side plate is located between two adjacent frames, so that the four frames, together with the four side plates and the bottom plate, form a protective box.

[0013] Preferably, a finger groove is provided on one side of the side plate and below the card slot. The finger groove facilitates the user to push the side plate upward and to rotate the side plate outward.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] One of the side panels, during the process, rotates a rod that drives a bevel gear inside the slider to rotate. Under the action of another bevel gear, the other three side panels will also automatically open outwards simultaneously. Then, the user slides the side panel downwards and rotates it upwards to open the top cover, allowing the top cover to rotate to one side of the frame, changing it from horizontal to vertical. At the same time, the top cover engages with the slot on one side of the side panel. The four outwardly unfolded side panels form a bracket to support the surveillance camera. Finally, slide the movable seat upwards to raise the surveillance camera, and then rotate the surveillance camera to change it from vertical to horizontal. The side panels can be retracted by reversing the operation. The side panels, bottom plate, and top cover protect the surveillance camera. Because the protective box is composed of side panels, bottom plate, and top cover, and the side panels, bottom plate, and top cover can also act as a bracket when unfolded, the protective box is unlikely to be lost during each transfer of the surveillance camera, thus effectively protecting the surveillance camera.

[0023] 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.

[0024] Please see Figures 1 to 6 A construction site monitoring device includes a base plate 1, with four frames 2 fixedly connected to the top of the base plate 1. The four frames 2 are symmetrically distributed. Sliding blocks 3 are slidably connected to the inner side of the frames 2. Rotating rods 4 are rotatably connected between adjacent sliding blocks 3. Side plates 5 are sleeved on the outside of the rotating rods 4. The side plates 5 and the base plate 1 protect the monitoring camera 8. When unfolded, the side plates 5 can also serve as a bracket to support the monitoring camera 8. The side plates 5 are fixedly connected to the rotating rods 4. A fixed plate 6 is fixedly connected to the top of the base plate 1. A movable seat 7 is sleeved on the outside of the fixed plate 6. The movable seat 7 is slidably connected to the fixed plate 6. The monitoring camera 8 is rotatably connected to the inner side of the movable seat 7. The monitoring camera 8 monitors the construction site.

[0025] Furthermore, the rotating rod 4 passes vertically through the slider 3 and extends into the interior of the slider 3. Both ends of the rotating rod 4 are fixedly connected with bevel gears 9. Adjacent bevel gears 9 mesh with each other. Under the action of the bevel gears 9, when one of the four side plates 5 is rotated and unfolded, the other three will also unfold at the same time. In this way, the user only needs to operate one side plate 5, which simplifies the operation steps.

[0026] Furthermore, a top cover 10 is rotatably connected to the outside of the frame 2. A first magnetic piece 11 is fixedly connected to the outside of the top cover 10 near the side of the frame 2. A first iron piece 12 is fixedly connected to the top of the frame 2. The first iron piece 12 and the first magnetic piece 11 work together. A slot 13 is provided on one side of one of the side plates 5. The slot 13 works together with the top cover 10. When the side plate 5 is unfolded, the top cover 10 can be rotated from the top to the side. Then, the top cover 10 can be inserted into the slot 13 to limit the position of the unfolded side plate 5.

[0027] Furthermore, a second magnetic sheet 14 is fixedly connected to the bottom of the side plate 5 and below the slot 13, and a second iron sheet 15 is fixedly connected to the top of the base plate 1. The second iron sheet 15 and the second magnetic sheet 14 are used together to limit the position of the side plate 5.

[0028] Furthermore, both the frame 2 and the slider 3 have an L-shaped cross-section. The outer wall of the slider 3 fits into the inner wall of the frame 2. The side plate 5 is located between two adjacent frames 2, so that the four frames 2, together with the four side plates 5 and the bottom plate 1, form a protective box for protecting the surveillance camera 8.

[0029] Furthermore, a finger groove 16 is provided on one side of the side plate 5 and below the slot 13. The finger groove 16 facilitates the user to push the side plate 5 upward and to rotate the side plate 5 outward.

[0030] The usage steps of this utility model are as follows: When using this construction site monitoring device, one of the side plates 5 is opened by rotating the finger groove 16 outward. During the opening of this side plate 5, the bevel gear 9 inside the slider 3 will rotate through the rotating rod 4. Under the action of the other bevel gear 9, the other three side plates 5 will also open outward automatically at the same time. Then, the user slides the side plate 5 downward and rotates the top cover 10 upward to open it, so that the top cover 10 rotates to one side of the frame 2, so that the top cover 10 changes from horizontal to vertical. At the same time, the top cover 10 engages with the slot 13 on one side of the side plate 5. The four side plates 5 are then opened outward. A support bracket is formed to support the surveillance camera 8. Finally, the movable seat 7 is slid upward to lift the surveillance camera 8. Then, the surveillance camera 8 is rotated to change it from vertical to horizontal. The side plate 5 can be retracted by reversing the operation. The side plate 5, the bottom plate 1, and the top cover 10 are used to protect the surveillance camera 8. Since the protective box is composed of the side plate 5, the bottom plate 1, and the top cover 10, and the side plate 5, the bottom plate 1, and the top cover 10 can also act as a support when unfolded, the protective box is unlikely to be lost during each transfer of the surveillance camera 8, thus effectively protecting the surveillance camera 8.
