Description

Technical Field

[0001] The utility model relates to the technical field of public safety monitoring, in particular to a movable public safety monitoring device. Background Art

[0002] Public security monitoring equipment is mainly composed of two parts: front-end equipment and back-end equipment. The front-end equipment is usually composed of cameras, manual or electric lenses, pan / tilt heads, protective covers, listeners, alarm detectors and multi-function decoders. They each have their own functions and establish corresponding connections with various equipment in the central control system through wired, wireless or optical fiber transmission media (transmitting video / audio signals and control and alarm signals). Mobile video surveillance devices are needed in the management of some construction sites or monitoring blind spots.

[0003] The current monitoring equipment has a simple structure, is easy to use, and does not require wiring or installation. For example, in the prior art, Chinese patent application number CN202022038161.3 discloses a movable monitoring device, including a box, a self-locking drawer, a retractable mast fixed to the box, and a detachable crossbeam fixed to the mast, wherein the crossbeam is provided with a fixing device, and the fixing device fixes a monitoring component for collecting images, and the box contains image processing, storage and transmission components, and the box also includes a mast control lifting component and a battery for powering the monitoring component, and the drawer is configured with an application tablet that can display and control the monitoring component.

[0004] The monitoring components of the monitoring equipment in the prior art are arranged on the crossbeam at the top of the mast, which can realize highly controllable all-round monitoring. However, due to the height limitation of the retractable mast, the current monitoring equipment cannot completely store the camera and other structures, resulting in the loss of convenience of the mobile monitoring equipment. In addition, the bumps and vibrations generated during transportation may cause damage to the camera, affecting the safety of the camera. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that due to the height limitation of the retractable mast, structures such as the camera cannot be completely stored, thereby reducing the convenience brought by the mobile monitoring equipment, and to propose a movable public safety monitoring equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] The inner sides of the shell are both fixedly connected with limit rods, and the limit rods are slidably connected with the corresponding limit holes respectively.

[0011] By adopting the above technical solution, the position of the mounting plate is further limited by the connection between the limiting rod and the limiting hole, thereby ensuring the stability of the mounting plate when being lifted and lowered and enhancing the support of the mounting plate.

[0012] Furthermore, the limiting rods are coaxially fixedly connected with limiting rings, and the limiting rings are abutted against the mounting plates.

[0013] By adopting the above technical solution, the lowest position of the mounting plate is limited by a limit ring to avoid excessive downward adjustment of the mounting plate and collision with the first motor as much as possible, while ensuring the fit between the protective shell and the lifting slot port.

[0014] Furthermore, the outer fixing sleeve of the camera is provided with a protective shell, and the size of the protective shell is equal to the size of the lifting slot.

[0015] By adopting the above technical solution, the protective shell can enhance the protection effect of the camera when the camera is protruding from the shell, and when the camera is stored, the protective shell fits with the port of the lifting slot to close the port of the lifting slot, so that the shell can ensure that the internal space is sealed as much as possible, dust-proof and the protection effect is enhanced.

[0016] Furthermore, heat dissipation holes are provided on both sides of the protective shell.

[0017] By adopting the above technical solution, the heat generated when the camera is running can be discharged through the heat dissipation holes, thereby minimizing damage to the camera due to overheating.

[0018] Furthermore, a rotating rod is fixedly connected to the bottom of the protective shell, and the other end of the rotating rod is rotatably connected to the mounting plate.

[0021] One end of the rotating rod away from the protective shell extends to below the mounting plate and is fixedly connected with a driven gear, and the driven gear is meshedly connected with the driving gear.

[0022] By adopting the above technical solution, the second motor can drive the transmission shaft and the driving gear to rotate together. When the driving gear rotates, the rotating rod and the protective shell are driven to rotate through the meshing driven gear, thereby realizing the 360-degree automatic rotation adjustment of the camera and improving the visual range of the monitoring equipment.

[0023] The utility model provides a movable public safety monitoring device, which has the following beneficial effects:

[0024] 1. The utility model can push and pull the outer shell for displacement by setting walking wheels in cooperation with the push rod, thereby improving the convenience during transportation, and the walking wheels can adopt locking universal wheels. When the monitoring equipment is stationary, the position of the outer shell can be fixed by the brake pads. The mounting plate plays the main role of supporting and adjusting the camera. The mounting plate can drive the camera to extend out along the lifting slot or be stored in the inner shell. On the one hand, it ensures the convenience of moving the monitoring equipment, and on the other hand, it protects the safety of the camera during mobile transportation and when not in use.

[0025] 2. The utility model provides a protective shell, which can enhance the protection of the camera when the camera is protruding from the shell. When the camera is stored, the protective shell fits with the port of the lifting slot to close the port of the lifting slot, so that the shell can ensure that the internal space is sealed as much as possible, dustproof and the protection effect is enhanced. The heat generated by the camera during operation can be discharged through the heat dissipation holes, so as to avoid damage to the camera due to overheating.

[0026] 3. The utility model uses a second motor, and the second motor can drive the transmission shaft and the driving gear to rotate together. When the driving gear rotates, the meshing driven gear drives the rotating rod and the protective shell to rotate, thereby realizing 360-degree automatic rotation adjustment of the camera and improving the visual range of the monitoring equipment.
