Description

Technical Field

[0001] The utility model relates to the technical field of monitoring auxiliary equipment, in particular to an auxiliary bracket for a camera on a construction site. Background Art

[0002] Concrete pouring refers to the process of pouring concrete into the formwork according to the design requirements, removing bubbles and vibrating to form a uniform and solid concrete structure. This process includes processes such as spreading, vibrating, and troweling. It is usually used in infrastructure projects such as buildings, roads, and bridges, and is one of the key links in engineering construction. During the concrete pouring process, adding water is expressly prohibited, so professional engineers are required to supervise on-site to prevent the addition of water. With the continuous development of video surveillance technology, the concrete pouring process can be monitored in real time through surveillance cameras, thereby replacing on-site supervision by engineers.

[0003] In order to facilitate the movement of surveillance cameras to adapt to different concrete pouring construction sites on the construction site, the surveillance cameras are usually fixed on a movable bracket, but there are generally no dust prevention measures, so the cameras are easily contaminated with dust, resulting in blurred camera vision and affecting the monitoring of the construction site. Therefore, the on-site cameras need to be cleaned in time. However, there is a lot of dust in the construction site environment, and there are also many stains caused by cement and sand, which makes it difficult for on-site workers to always have clean paper or cloth to wipe the cameras in time. Therefore, there is an urgent need for a device that can facilitate on-site personnel to quickly clean the cameras to solve the problem of inconvenient camera wiping. Utility Model Content

[0004] In order to overcome the problem in the prior art that construction site cameras are easily contaminated with dust, which results in the camera often needing to be cleaned but is inconvenient to clean, the embodiment of the utility model provides an auxiliary bracket for the construction site camera. The technical solution is as follows:

[0005] An auxiliary bracket for a construction site camera comprises a support frame and a wiping mechanism arranged at the upper end of the support frame, the wiping mechanism comprises a base connected to the upper end of the support frame, an outer arc cover is fixed to the upper end surface of the base, an inner arc cover is rotatably arranged inside the outer arc cover, the outer wall of the inner arc cover is fitted with the inner wall of the outer arc cover, and the outer arc cover is concentrically arranged with the inner arc cover, the camera is arranged on the base, a flexible wiping piece is arranged on the inner wall of the inner arc cover, the other side of the wiping piece is tightly against the spherical surface of the camera, and a driving mechanism for driving the inner arc cover to rotate is connected to the center position of the top end of the inner arc cover.

[0006] Furthermore, the driving mechanism includes a connecting rod rotatably connected to the outer arc cover through a bearing, the outer ring of the bearing is fixedly arranged at the center position of the top end of the outer arc cover, the connecting rod passes through the inner ring of the bearing and is fixedly connected thereto, one end of the connecting rod is fixedly connected to the inner arc cover; the other end of the connecting rod is connected to a turning handle, or the other end of the connecting rod is connected to a motor.

[0007] Furthermore, the wiping piece is attached to the inner wall of the inner arc-shaped cover by Velcro, so that the wiping piece can be replaced conveniently later.

[0008] Furthermore, there are two wiping pieces, which are spaced apart circumferentially along the inner wall of the inner arc-shaped cover. One of the two wiping pieces can be used to repeatedly wipe the camera first, and then the other wiping piece can be used to wipe it again. This method has a better cleaning effect.

[0009] Furthermore, the wiping piece is a sponge block or a cotton cloth block.

[0010] Furthermore, the outer arc-shaped cover and the inner arc-shaped cover are both hemispherical, and the lower end surfaces of the outer arc-shaped cover and the inner arc-shaped cover are both in contact with the upper end surface of the base.

[0011] Furthermore, a through hole is provided on the lower end surface of the base, and a sealing sleeve is provided on the lower end surface of the base at the through hole, and the sealing sleeve can prevent dust from entering the closed inner and outer arc-shaped covers through the through hole.

[0012] Furthermore, the support frame is a tripod, which is easy to move and relatively stable.

[0013] The beneficial effects of the technical solution provided by the embodiment of the utility model are as follows: the bracket has a simple structure and is easy to use. It can clean the camera quickly and conveniently in an environment with a lot of dust or pollutants. The outer arc cover and the inner arc cover can also be closed when not in use or suspended, so that the camera is in a closed space to prevent dust from entering. It is highly practical and can be used in a turnover manner. The bracket can clean the camera conveniently and effectively by repeatedly wiping the camera with the rotating inner arc cover and two wiping members at a certain distance.
