It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Aiming at the prior art, the problem to be solved by the application is that the cleaning device of the current explosion-proof camera needs to be electrified to operate, and a structure meeting the explosion-proof requirement needs to be specially designed for the cleaning device in an explosion-proof occasion, so the manufacturing cost is higher, and the installation and the maintenance are difficult.

Referring to the attached drawing 1 of the specification, the explosion-proof camera with the pressing type water spray cleaning device mainly comprises a base 1, a tripod head 2, a camera module 3 and a cleaning device 4. The pan/tilt head 2 can rotate 360 degrees on a horizontal plane, and the pitch angle can be adjusted in a vertical plane perpendicular to the horizontal plane. The camera module 3 comprises a camera 31, a camera protective cover 32, a window 33 and a pressing structure 34, wherein the pressing structure 34 is arranged on the lower edge of the camera protective cover 32 and located on the lower portion of the window 33. The cleaning device 4 includes a nozzle 41, a pressing head 42, a pressing device 43, and a liquid storage container 44. As shown in fig. 1, the washing device 4 is located on one side of the base 1 in a non-washing state or a state before washing is performed. When the camera module 3 rotates to the length direction through the holder 2 and is parallel to the connecting line of the cleaning device 4 and the base 1, the cleaning device 4 can be positioned below the window 33 of the camera module 3.

Refer to the description and the attached fig. 2, which is the state of the explosion-proof camera of the present application when cleaning is performed. When the camera module 3 is driven by the holder 2 to rotate to a position where the length direction of the camera module is parallel to the connecting line between the cleaning device 4 and the base 1, the holder 2 adjusts the pitch angle, so that one end of the window 33 of the camera module 3 moves downwards. After one end of the window 33 of the camera module 3 moves downwards for a certain distance, the pressing structure 34 can contact with the pressing head 42 of the cleaning device 4, and the pressing operation of the pressing head 42 is realized through the pressing structure 34 in the subsequent process of continuing to move downwards at one end of the window 33. The pressing operation of the pressing head 42 will enable the pressing device 43 to eject the cleaning liquid in the reservoir 44 through the nozzle 41. As shown in fig. 1 and 2, the nozzle 41 extends laterally from one side of the pressing head 42 and then has an upward bent structure, so that the nozzle opening of the nozzle 41 can be directed toward the viewing window 33 during the process of moving downward at one end of the viewing window 33 of the camera module 3 and pressing the pressing head 42.

In order to ensure that the pressing structure 34 can accurately press the pressing head 42, the pressing structure 34 may be designed to have a cylindrical shape, a rectangular parallelepiped shape, a nut semicircular shape, and the like, and may be fixedly connected to the lower edge of the front end of the camera protection cover 32 by a fixing means such as a screw or a snap. Preferably, the pressing structure 34 and the camera protection cover 32 may be integrally formed, for example, the lower edge of the front end of the camera protection cover is directly designed as a protruding cylindrical housing, and the width of the protruding cylindrical housing is sufficient to ensure the accurate pressing of the pressing head 42.

When the explosion-proof camera generally works, the direction of the camera generally does not necessarily face the pressing head 42 of the cleaning device, so that the holder can be quickly adjusted to a position where cleaning can be carried out by setting a preset position. Specifically, after the cleaning device is fixed, the optimum point for pressing the pressing head 42 is preset and recorded in the memory of the decoding board. In this preset position, it is ensured that the viewing window 33 is positioned directly opposite the nozzle 41 and that the pressing position is the optimal position. The calling precision of the preset position can reach the angle range of +/-0.1 degree, and the holder 2 automatically rotates to the position only by calling the preset position, so that the pressing head 42 is accurately extruded, and the window 33 can be positioned at the position where water flow sprayed by the nozzle 41 can be sprayed.

The structure of the pressing device 43 is shown in fig. 3 of the specification, and includes, from top to bottom, an upper glass ball 431, a main post 432, a locking cover 433, a spacer 434, a screw thread 435, a piston 436, a sub-post 437, a spring 438, a body 439, a lower glass ball 4310, and a suction pipe 4311. When the pressing head 42 is pressed on the pressing device 43, the main structure of the pressing device 43 is also pressed, so that the suction pipe 4311 can suck out the cleaning liquid in the liquid storage tank 44 and eject the cleaning liquid from the pressing head 42 and the nozzle 41. As shown in fig. 3, the nozzle 41 has a hollow structure and is connected to the pressing head 42. The pressing head 42 has a buffer chamber 421 therein to communicate a pipe line in the pressing device 43 with a hollow pipe line of the nozzle 41.

Further, as shown in fig. 4 in the specification, the explosion-proof camera further includes a wiper blade 5, and the wiper blade 5 can scrape the glass of the window 33 while the cleaning liquid is ejected from the nozzle 41. The windscreen wiper 5 is controlled by an internal decoding board, and when the decoding board controls the holder to rotate to a specified position and extrudes the pressing head 42, an electric signal is sent to operate the windscreen wiper 5, so that a linkage function is realized.

The above describes an explosion-proof camera with a press type water jet cleaning device of the present application. Because the cleaning device only needs to utilize the power of other parts of the anti-explosion camera, the cleaning function can be started in a mechanical mode, so that the cleaning device in the application does not need to be provided with any electric equipment such as a motor and an electromagnetic valve, and the function of automatically cleaning the window glass of the camera in an anti-explosion occasion can be realized without carrying out special anti-explosion structural design on the cleaning device. Therefore, the cost of the whole equipment of the explosion-proof camera is low, and the installation, maintenance or replacement of the cleaning device is simpler and more convenient.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
