At this time, the tension spring 13 is in a stretched state; a camera module 3 is installed in the sliding protective shell 2, and the lens of the camera module 3 faces forward; a liquid storage tank 41 is fixedly connected to the fixed frame 1, and the liquid storage tank 41 is filled with cleaning liquid; a micro pump 42 is installed on the fixed frame 1; the inlet end of the micro pump 42 is connected to the liquid storage tank 41; the outlet end of the micro pump 42 is connected to two delivery pipes 43; one connecting pipe 44 is connected to each of the two delivery pipes 43; an annular pipe 45 is fixedly connected in the sliding protective shell 2; the two connecting pipes 44 are jointly connected to the annular pipe 45; a number of spray heads 451 facing the lens surface of the camera module 3 are connected to the annular pipe 45; remote signal transceiver modules are installed in the electric control rotating shaft 14, the electromagnet 21, the camera module 3 and the micro pump 42.

[0019] As Figure 5 shown, an annular inner groove 301 structure is provided on the front side of the camera module 3; a lighting lamp 31 is fixedly connected in the annular inner groove 301 of the camera module 3; a circle of light condensing sheets 32 is provided on the inner ring surface of the annular inner groove 301 of the camera module 3.

[0020] As Figures 3-5 shown, a circular groove 201 structure is provided on the sliding protective shell 2, and the circular groove 201 is wound around the outside of the lens of the camera module 3; the two connecting pipes 44 are respectively arranged in a repeated S-shaped structure on the left and right sides of the camera module 3; a waste discharge pipe 5 is fixedly connected in the sliding protective shell 2; a liquid inlet channel 501 structure communicating with the bottom of the circular groove 201 is provided on the waste discharge pipe 5; the outlet end of the waste discharge pipe 5 is aligned downward between the fixed frame 1 and the liquid storage tank 41; a number of heat dissipation grooves 202 structures penetrating in the front and rear directions are provided on the sliding protective shell 2.

[0021] The following is a method for using an intelligent monitoring camera at a construction site of the present invention.

[0022] First, the constructor inserts the two clamping legs 11 of the fixing frame 1 together on the upper edge of the target filling hopper. The fixing frame 1 is firmly clamped on the target filling hopper through the two clamping legs 11, so that the camera module 3 is located on the front side of the slide rail 12 and shoots downward into the filling hopper. Then, turn on the lighting lamp 31 in the camera module 3. The light emitted by the lighting lamp 31 is irradiated into the filling hopper under the focusing action of the condenser lens 32, so as to illuminate the inside of the filling hopper under insufficient light conditions, and complete the positioning and fixing of the fixing frame 1 on the filling hopper. Subsequently, start the concrete filling work into the filling hopper. At this time, the constructor can monitor the concrete filling state inside the filling hopper through the camera module 3 by using the remote signal transceiver module, keeping the constructor away from the dangers around the filling hopper.

[0023] During the concrete filling work, the constructor controls the electric control rotating shaft 14 through the remote signal transceiver module to drive the slide rail 12 to rotate in the up and down directions. The camera module 3 in the sliding protective shell 2 will also rotate in the up and down directions with the slide rail 12, realizing the adjustment of the shooting angle of the camera module 3 inside the filling hopper, enabling the constructor to monitor the concrete filling states in multiple areas inside the filling hopper through the camera module 3. At the same time, the lighting lamp 31 will also rotate in the up and down directions with the camera module 3, keeping the light emitted by the lighting lamp 31 irradiating the area photographed by the camera module 3 in the filling hopper, so as to illuminate the current photographed area inside the filling hopper under insufficient light conditions.

[0024] When the constructor observes that concrete splashes onto the lens surface of the camera module 3, the constructor turns on the micro pump 42 through the remote signal transceiver module. The micro pump 42 continuously transports the cleaning liquid in the liquid storage tank 41 through the delivery pipe 43 and the connecting pipe 44 to the annular pipe 45. The cleaning liquid is sprayed out onto the lens surface of the camera module 3 through each nozzle 451 of the annular pipe 45 respectively, and the concrete splashed onto the lens surface of the camera module 3 is washed in time by the cleaning liquid. The waste water formed after the cleaning liquid flushes the concrete will flow along the annular groove 201 to the liquid inlet channel 501 of the waste discharge pipe 5, and then the waste water is discharged out of the filling hopper along the waste discharge pipe 5 to the outside of the filling hopper, preventing a large amount of cleaning liquid waste water from entering the filling hopper with the concrete and interfering with the concrete filling work.

[0025] During this process, the cleaning liquid flowing along the connecting pipe 44 will closely adhere to the outer surface of the camera module 3 to perform water-cooling heat dissipation treatment on it. At the same time, the sliding protective shell 2 can also improve the heat dissipation effect on the camera module 3 by means of the heat dissipation grooves 202, realizing that the camera module 3 can also obtain sufficient heat dissipation treatment even under long-term exposure conditions, ensuring the continuous and stable progress of the shooting work of the camera module 3.

[0026] In addition, when the construction worker observes the abnormal phenomenon that a large number of bubbles emerge from the concrete filled in the filling hopper, some concrete will be splashed onto the lens surface of the camera module 3 along with the abnormally splashing bubbles. At this time, the construction worker immediately activates the electromagnet 21 through the remote signal transceiver module, so that the electromagnet 21 generates a magnetic field repulsive to the permanent magnet 121, making the iron core in the electromagnet 21 no longer generate electromagnetic attraction with the permanent magnet 121. At the same time, the tension spring 13 initially in the stretched state pulls the sliding protective shell 2 to drive the camera module 3 to move upward along the slide rail 12 to the outside of the filling hopper, so that the camera module 3 is away from the filling hopper, avoiding the camera module 3 from being contaminated by the splashed concrete.

[0027] Embodiment 2: As Figures 1-5 shown, on the basis of Embodiment 1, a transfer ring 61 is rotatably connected to the camera module 3; a scraping blade 62 is fixedly connected to the transfer ring 61; the scraping blade 62 is closely attached to the lens surface of the camera module 3; a rotating handle 63 is rotatably connected to the transfer ring 61.

[0028] When some of the concrete adhered to the lens surface of the camera module 3 cannot be washed clean by the cleaning liquid sprayed by the nozzle 451, the construction worker only needs to hold the rotating handle 63 to drive the transfer ring 61 to rotate. The transfer ring 61 will drive the scraping blade 62 to rotate around the lens surface of the camera module 3. The scraping blade 62 moving closely attached to the lens surface of the camera module 3 and the cleaning liquid flushed onto the lens surface of the camera module 3 work together to clean the concrete residue on the lens surface of the camera module 3.

[0029] Embodiment 3: As Figures 1-5 shown, on the basis of Embodiment 1, a fixed protection plate 15 is fixedly connected to the top of the sliding protective shell 2; an elastic telescopic protection plate 16 is fixedly connected between the fixed protection plate 15 and the slide rail 12.

[0030] In the initial state, the sliding protective shell 2 is located on the front side of the slide rail 12. Therefore, the elastic telescopic protection plate 16 will be in the stretched state to provide protection above the slide rail 12, and at the same time, the fixed protection plate 15 provides protection above the sliding protective shell 2. At the beginning stage of the concrete filling work, if the distance between the outlet end of the concrete filling head and the sliding protective shell 2 is relatively close and does not align with the center of the filling hopper, the concrete sprayed from the outlet end of the concrete filling head may directly spray onto the sliding protective shell 2 and the slide rail 12. At this time, the fixed protection plate 15 and the elastic telescopic protection plate 16 respectively provide protection for the sliding protective shell 2 and the slide rail 12 from above, avoiding a large amount of concrete from falling and accumulating on the sliding protective shell 2 and the slide rail 12 and affecting their moving effect. Then, the construction worker timely adjusts the position of the concrete filling head, making the outlet end of the concrete filling head away from the sliding protective shell 2 and align with the center of the filling hopper.

[0031] After the concrete filling work starts, when the construction worker observes that there is an abnormal phenomenon of a large number of bubbles emerging in the concrete filled in the filling hopper, the construction worker immediately activates the electromagnet 21 through the remote signal transceiver module according to the above steps. The sliding protective shell 2 is pulled by the tension spring 13 to drive the camera module 3 to move upward along the slide rail 12 to the outside of the filling hopper, so that the camera module 3 is far away from the filling hopper, avoiding the camera module 3 being contaminated by the splashing concrete on a large area. During the process of the tension spring 13 pulling the sliding protective shell 2 to move upward, the sliding protective shell 2 will also push the elastic telescopic guard plate 16 to contract upward. After the elastic telescopic guard plate 16 is contracted, it will act as an elastic buffer block to block between the sliding protective shell 2 and the slide rail 12, so that the sliding protective shell 2 pulled upward by the tension spring 13 can be buffered by the elastic telescopic guard plate 16 acting as an elastic buffer block in time and slowly stop moving, avoiding the sliding protective shell 2 colliding with the contracted tension spring 13 under the inertial action of the upward impact, resulting in damage to the camera module 3 in the sliding protective shell 2 during the collision process, and realizing the buffer protection for the camera module 3 in the sliding protective shell 2.

[0032] In addition, when the construction worker observes that there is a more violent abnormal phenomenon of bubbles emerging in the concrete filled in the filling hopper, the construction worker immediately activates the electromagnet 21 through the remote signal transceiver module according to the above steps. The sliding protective shell 2 is pulled by the tension spring 13 to drive the camera module 3 to move upward along the slide rail 12 to the outside of the filling hopper, so that the camera module 3 is far away from the filling hopper. At the same time, the construction worker controls the electric control rotating shaft 14 through the remote signal transceiver module to drive the slide rail 12 to turn upward, so that the slide rail 12 drives the camera module 3 in the sliding protective shell 2 to turn upward, making the lens of the camera module 3 turn to an upward inclined state, avoiding a large amount of concrete being splashed onto the lens of the camera module 3 along with the violently emerging bubbles, and realizing the isolation protection for the lens of the camera module 3.
