Description

Overheat protection device for television camera in hearth

Technical Field

The utility model belongs to the technical field of the camera technique and specifically relates to indicate an overheat protection device of TV set camera in furnace.

Background

The smart television can realize various application services such as network search, IP television, video on demand, digital music, network news, network video telephone and the like, the application services can not be separated from a video acquisition device, such as a camera in a hearth of a power plant, and need to be monitored by a television camera, it adopts an external camera which is hung outside a television shell, wherein the camera usually adopts cooling air to carry out air cooling directly, in practical application, if the cooling air is interrupted midway, if a monitoring person does not find abnormality and starts the key action motor to drive the television and the camera to exit from a hearth in time, the camera can cause the problems of coking of high-temperature lenses, blurred pictures, lost picture signals and the like due to overhigh temperature, the judgment of operating personnel on the combustion working condition of the hearth is seriously influenced, and the service lives of the television and the camera can be shortened.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide an overheat protection device of TV set camera in furnace, structural design is simple reasonable, can avoid high temperature to damage the camera, and then prolongs the life of TV set and camera. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The overheating protection device for the television camera in the hearth comprises a camera, a television and a cooling air source, wherein a lens is arranged at the front end of the camera, the camera is connected to the front of the television, the television can move inside and outside the hearth through a walking motor assembly, the cooling air source is connected with a first air pipe, a pressure sensor is arranged on the first air pipe and is electrically connected to the walking motor assembly, the first air pipe is connected with a second air pipe and a third air pipe through a three-way pipe, the air outlet end of the second air pipe is aligned with the lens, and the air outlet end of the third air pipe is aligned with the camera.

Furthermore, a filtering pressure reducing valve is arranged on the first air pipe and is arranged in front of the pressure sensor.

(III) advantageous effects

Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, the utility model discloses an add pressure sensor and judge whether the sufficient supply of cooling air, if the cooling air supply is interrupted or not enough, and then control action motor element in time withdraws from furnace with TV set and camera, not only effectively guarantees that TV set and camera are not burnt out, has prolonged the life of equipment, has practiced thrift the cost of enterprises.
