Preferably, a compression spring 27 is fixedly mounted on one side of the connecting plate 26, the other end of the compression spring 27 is fixedly mounted on the inner wall of the mounting base 23, and a handle 28 is bolted to the other side of the movable plate 24. The handle 28 is provided to facilitate manual opening of the movable plate 24, and the installation is more convenient.

In addition, as shown in fig. 1 and 5, a shock absorption base 29 is further arranged between the bottom of the groove of the mounting base 23 and the bottom of the shell 1, and the thickness of the shock absorption base 29 is 3-5 cm; through the arrangement of the shock absorbing base 29, the housing 1 collides with the mounting base 23 when descending in the mounting process, and the shock absorbing base 29 plays a role in shock absorbing and protecting the device.

The device of the invention is mounted on a mounting structure, and the operation is as follows: firstly, the device is fixed at the position where the device needs to be installed on the installation base 23 through expansion bolts, meanwhile, the device is lifted up and positioned above the damping base 29, the movable plates 24 are pulled through the handles 28, the movable plates 24 on the two sides are enabled to move in opposite directions, the connecting plate 26 moves along with the movable plates to enable the compression spring 27 to be in a compression state, then, the device is descended, the device is enabled to be positioned above the inner side of the installation base 23 and to be in contact with the damping base 29, then, the fixed groove 25 on the surface of the shell 1 is aligned with the movable plates 24, the handles 28 are loosened, and under the reaction force of the compression spring 27, the connecting plate 26 and the movable plates 24 move towards the shell 1, so that the movable plates 24 enter the inside of the fixed groove 25, and the installation is completed.

The device of the invention has the working procedures as follows: before the work, adjust carousel 4 through elevating system and be located casing 1 top (also can control the height of control), can open first motor 14, it drives through the gear and rotates post 13 and begin to rotate, later it drives carousel 4 and begins to rotate post 13, it makes the surveillance camera head 5 at carousel 4 top begin to rotate, thereby change the control visual angle of camera, enlarge monitoring range, and surveillance camera head 5, temperature and humidity sensor 6, air velocity transducer 7, the data that dust sensor 8 and noise sensor 9 monitored can be transmitted for data receiving module 10, and pass through wireless transmission module 11 and upload for monitoring platform, thereby accomplish wireless monitoring.

If the camera and the sensor are covered by a large amount of dust to affect the operation, the second motor 151 is turned on to drive the first screw 152 and the second screw 153 to start to rotate, then the movable blocks 155 on both sides drive the fixed platform 12 and the rotating disk 4 to descend together under the action of the screw threads until the striker 162 contacts with the first travel switch 161, the processing module 2 controls the fan 18 and the dust collector 3 to be turned on, the fan 18 generates a rightward airflow to enter the inside of the housing 1, and blows the dust on the surfaces of the camera and the sensor to float, meanwhile, the dust floating near the dust hood 20 is captured by the vacuum generated by the dust collector 3, and then the dust enters the inside of the dust collector 3 through the dust hood 20 and the communication pipeline 21, thereby completing the cleaning. More optimally, the first motor 14 can be started to rotate the turntable 4 in the dedusting process, so that different positions of the sensor and the camera can be affected by wind, the cleaning is more thorough, and the cleaning is faster.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
