DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-4 As shown, a multifunctional campus security monitoring device comprises a base 1, a spherical camera 2 is installed on the lower side of the base 1, an arc rod 3 is hinged at the front and rear sides of the lower side of the base 1, an arc scraper 4 matching the spherical camera 2 is installed on the upper side of the arc rod 3, a transmission component for driving the arc rod is installed on the side of the base 1, a timer is arranged on the inner side of the base 1, and the timer is electrically connected to the transmission component;

[0021] A solar panel 5 is installed on the upper side of the base 1, and a battery electrically connected to the solar panel 5 is installed on the inner side of the base 1;

[0022] The transmission assembly includes a slide rail 6, which is horizontally installed on the left and right sides of the base 1 in the front and back directions. A first gear 7 is installed on the lower side of the slide rail 6 to be rotatably connected to the base 1 and to be transmission-connected to the arc rod 3. A second gear 8 meshing with the first gear 7 is rotatably installed on the upper side of the first gear 7. A long rod 9 is fixedly installed on the upper side of the second gear 8. A straight slot 10 is vertically opened on the upper side of the long rod 9. A vertical rod 11 is slidably installed on the upper side of the slide rail 6 in the front and back directions. A connecting column 12 matching the straight slot 10 is fixed on the lower end of the vertical rod 11. A screw rod 13 facing horizontally in the front and back directions is rotatably installed on the side of the base 1. The screw rod 13 is threadedly connected to the vertical rod 11. A motor 14 is installed on the front side of the screw rod 13. The output end of the motor 14 is transmission-connected to the screw rod 13.

[0023] A cross bar 15 is installed between the upper ends of the left and right vertical bars 11 , and a straight scraper strip 16 is installed on the lower side of the cross bar 15 .

[0024] The base 1 is fixed to the wall at the designated position by bolts. After being used for a period of time, the spherical camera 2 will be contaminated with dust. When the utility model is not in use, the arc rod 3 is in a nearly horizontal state. When the arc rod 3 needs to be used, the transmission component can control the arc rod 3 to swing back and forth, and the arc scraper 4 inside the arc rod 3 can wipe the spherical camera 2, thereby ensuring the clarity of the monitoring device. The timer can control the transmission component to clean the spherical camera 2 at regular intervals, solving the trouble of the staff needing to climb up to wipe the dust from the camera, thereby improving the safety and convenience of the monitoring device.

[0025] The solar panel 5 can generate electricity when exposed to sunlight and store it in the battery. The solar panel 5 and the battery can avoid laying a large number of wires, reduce line failures, and make maintenance more convenient. At the same time, it can also reduce the impact of power outages, line failures, etc. on the camera, and improve the stability and reliability of the system;

[0026] When the transmission assembly is in use, the motor 14 drives the screw rod 13 to rotate, which can control the vertical rod 11 to move forward and backward, and the connecting column 12 abuts against the inner side of the straight slot 10. At this time, the long rod 9 can convert the forward and backward movement of the vertical rod 11 into the left and right rotation of the second gear 8 and drive the first gear 7 to rotate. At this time, the arc rod 3 swings back and forth driven by the first gear 7; the cooperation between the screw rod 13 and the vertical rod 11 makes the control of the transmission assembly more delicate. At the same time, since the screw rod 13 has a one-way locking feature, it can prevent the arc rod 3 from sliding downward when not in use, avoiding the situation of blocking the field of view of the spherical camera 2, thereby improving the reliability of the monitoring device; the cross bar 15 and the straight scraper strip 16 enable the transmission assembly to clean the solar panel 5 when it is working, and restore the original light absorption rate of the photovoltaic panel.

[0027] A plurality of water spray heads 17 are evenly spaced and distributed on the side surfaces of the cross bar 15 and the arc-shaped bar 3 , and the water spray heads 17 are connected to an external water source.

[0028] When the arc scraper bar 4 and the straight scraper bar 16 are working, the water spray head 17 can spray water mist. Water is a natural solvent that can dissolve and disperse dust particles well, making them easier to wipe off. At the same time, spraying water to moisten the dust can reduce the direct contact between dust particles and the surface of the solar panel 5 and the spherical camera 2, thereby avoiding scratches.

[0029] An arc groove 18 matching the arc rod 3 , the arc scraper strip and the water spray head 17 is formed on the lower side of the base 1 .

[0030] The design of the arc groove 18 allows the arc scraper strip 4 to be controlled by the transmission assembly and hidden inside the arc groove 18 when not in use, thereby preventing the arc rod 3 from blocking the field of view of the spherical camera and being less affected by the external environment, such as ultraviolet rays, dust, etc., which helps to extend the service life of the arc scraper strip 4, reduce the replacement frequency, and reduce maintenance costs.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
