Heavy-load pan-tilt camera with high camera quality stability

Abstract

The invention discloses a heavy-load pan-tilt camera with high camera quality stability. A camera assembly and a zoom laser are arranged inside a shield of a camera, the zoom laser includes a zoom laser lens and a macro precision electric adjustment mechanism, and the macro precision electric adjustment mechanism includes a first adapter plate, a first motor, a second adapter plate and a second motor; the first motor is fixed relative to the shield and drives the first adapter plate to rotate horizontally; the second motor is fixed relative to the first adapter plate to drives the second adapter plate to rotate up and down; the zoom laser lens is fixed relative to the second adapter plate; a piece of electrically heated optical glass is arranged at the front end of the shield; a resistivecoating film is adhered to the surface of the optical glass, and two sides of the optical glass are electrically connected with a first electrode and a second electrode; a wiper is arranged corresponding to the optical glass and is used for cleaning the optical glass; a water storage container is also arranged on the shield, a waterway component is arranged inside the shield, and the waterway component includes a water pump, a water suction pipe and a water outlet pipe; and the water suction pipe is connected to the water storage container, and the water outlet pipe extends out of the front end of the shield to form a nozzle for cleaning the optical glass.

Description

technical field [0001] The invention relates to a pan-tilt camera, in particular to a heavy-duty pan-tilt camera with high camera quality and stability. Background technique [0002] Generally, a laser-type PTZ camera mainly includes two parts: a zoom laser and a camera. The design principle requires that the field of view of the camera is the same as the beam angle of the zoom laser. When the two are the same, the shooting effect is the best. Due to the deviation of the assembly process and the deviation of the machine itself, coupled with the long distance of laser irradiation, there are often problems with the consistency of the two, and they cannot be superimposed in the same area, resulting in the zoom laser not being able to play the role of auxiliary lighting , causing the camera to be unable to achieve long-distance visual photography. In the past, the solution to this problem was to adjust the beam angle by adjusting the free clearance of the screws and nuts on the...

Problems solved by technology

In bad weather or in a humid environment, as the internal camera and other components emit heat during operation, the temperature difference between the internal and external natural environment gradually increases. Therefore, the water vapor in the protective cover will gather on the optical lens, affecting The focus of the camera, resulting in blurred images, making the device unusable

The reasons for the above problems include: 1. There are air flow dead zones and low temperature zones in the shield; 2. The ambient humidity is high; 3. The camera has poor air permeability, and the air cannot be convected and exchanged

Since the heavy-duty PTZ camera requires to work outdoors and to rotate in all directions, the passport of the camera must have higher waterproof requirements, so it is impossible to open vents to increase air convection and exchange, otherwise there will be rainwater entering Camera causing equipment damage

[0004] In addition, the traditional PTZ camera has no water storage and water spray function. When the optical glass of the camera has dust and dirt, it cannot be cleaned, which seriously affects the optical performance, resulting in poor image quality and unclear viewing. It can be cleaned by the wiper when it rains, and the cleaning effect is poor when the rainfall is small, and it cannot be cleaned, which seriously affects the quality of monitoring

In order to ensure the image quality, the optical glass of the camera needs to be manually cleaned on a regular basis. Since the heavy-duty pan-tilt camera is a long-distance all-weather monitoring device, its installation point is usually relatively high, so manual maintenance and cleaning have the problems of long distances and high-altitude operations. , resulting in inconvenient maintenance, high maintenance cost and low efficiency
