DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

[0022] See also Figure 1-3 , a video monitoring device for a construction site, comprising a base plate 1 and a lens barrel 2, a cleaning mechanism 3 is fixedly connected to the side of the base plate 1, a fixing rod 5 is fixedly connected to the side of the base plate 1, and a circulating spraying mechanism 4 is fixedly connected to the side of the fixing rod 5;

[0023] The cleaning mechanism 3 includes a motor 31, and a reciprocating screw 32 is fixedly connected to the side of the motor 31. The reciprocating screw 32 is a mechanical transmission device for converting rotational motion into reciprocating motion. The threaded screw is a cylinder with threaded lines. The side of the reciprocating screw 32 is threadedly connected to a screw slider 33, and the side of the screw slider 33 is fixedly connected to a limit plate 34. The motor 31 is fixedly connected to the side of the base plate 1, and the limit plate 34 is fixedly connected to the side of the base plate 1. A connecting rod 35 is fixedly connected to the side of the connecting rod 35, and a scraper 36 is fixedly connected to the side of the connecting rod 35. A light switch 37 is arranged on the side of the motor 31. The light switch 37 is a device that can sense the intensity of light and adjust the light intensity according to the light intensity. A device for controlling a circuit switch according to a set threshold value, which is usually composed of a photosensitive element such as a photoresistor, a photodiode, etc. and a control circuit. A solar panel 310 is fixedly connected to the top of the base plate 1, a battery pack 39 is fixedly connected to the side of the solar panel 310, and a wire 38 is fixedly connected to the bottom end of the battery pack 39. One end of the wire 38 is fixedly connected to the battery pack 39, and the other end is fixedly connected to the motor 31 at the top. The present application absorbs solar energy through the solar panel 310 and converts it into electrical energy and stores it in the battery pack 39. The battery pack 39 supplies power to the motor 31, so that the scraper 36 can clean the stains and dust on the surface of the lens barrel 2 at night, and the lens position of the lens barrel 2 can be cleaned more effectively and controllably.

[0024] When the present embodiment is used, during the day, the solar panel 310 absorbs light energy and converts it into electrical energy and stores it in the battery pack 39. At night, the light sensor switch 37 senses that the surrounding environment has become darker and turns on the motor 31 on the side of the bottom plate 1. The motor 31 obtains electrical energy from the battery pack 39 through the wire 38 so that it can work normally. When the motor 31 is turned on, the reciprocating screw 32 fixedly connected to the side thereof starts to rotate, and the other end of the reciprocating screw 32 rotates in the limit plate 34. At this time, the screw slider 33 on the reciprocating screw 32 rotates due to the rotation of the reciprocating screw 32. As a result, the reciprocating screw rod 32 makes a reciprocating motion, and the connecting rod 35 fixedly connected to its side is also driven to make a reciprocating motion. At the same time, the scraper 36 is driven to make a reciprocating motion. The dust and other stains on the lens at the front end of the lens barrel 2 are cleaned by the reciprocating motion of the scraper 36. The motor 31 automatically turns off after the screw slider 33 reciprocates twice, so that the screw slider 33 returns to the initial position and waits for the next start-up. The electric energy obtained by the solar energy board provides energy for the motor 31, so that it drives the scraper 36 at night to clean the stains on the lens at the front end of the lens barrel 2.

[0025] Embodiment 2

[0026] See also Figure 4-6, a ring spraying mechanism 4 is added on the basis of the first embodiment, the circulating spraying mechanism 4 includes a water pump 41, a pressure rod 42 is fixedly connected to the bottom end of the screw slider 33, and a normally closed push switch 43 is arranged on the top of the water pump 41. The normally closed push switch 43 is a kind of contact in a closed state when the button is not pressed, and the circuit is energized. When the button is pressed, the contact is disconnected and the circuit is de-energized. A soft glue water pipe 44 is fixedly connected to the side of the water pump 41. The water pump 41 is fixedly connected to the side of the bottom plate 1, and the soft glue water pipe 44 is fixedly connected to the bottom end of the connecting rod 35. When the nozzle 45 moves with the screw slider 33, the soft glue water pipe 44 will stretch accordingly, which will not affect its normal movement. The side of the soft glue water pipe 44 is fixedly connected to the nozzle 45, and the bottom end of the water pump 41 is fixedly connected to A water suction pipe 46 is fixedly connected to the side of a water tank 47, one end of a fixing rod 5 is fixedly connected to the side of the base plate 1, and the other end is fixedly connected to the side of the water tank 47. The water tank 47 is fixed to the side of the base plate 1 by the fixing rod 5, and at the same time, it is below the moving direction of the scraper 36, ensuring that the cleaning liquid can be fully recovered. A filter screen 48 is fixedly connected inside the water tank 47. In this application, the cleaning liquid stored in the water tank 47 will be extracted through the water suction pipe 46 when the water pump 41 is working, and then pumped to the nozzle 45 for spraying by the water pump 41. The spilled cleaning liquid will eventually be filtered through the filter screen 48 and then returned to the water tank 47. The lens position of the lens barrel 2 can be cleaned more effectively by using the cleaning liquid, and a water cycle is formed without wasting water resources.

[0027] During use, on the basis of Example 1, when the screw slider 33 performs reciprocating motion, it will not restrict the normally closed push switch 43, so that the normally closed push switch 43 turns on the water pump 41, and the water pump 41 extracts the cleaning liquid in the water tank 47 through the suction pipe 46, and then transports it to the nozzle 45 through the soft glue water pipe 44 on its side, and the cleaning liquid is sprayed on the surface of the scraper 36 through the nozzle 45, so that it can more effectively clean the surface layer of the lens barrel 2, and after the cleaning liquid is sprayed out at the nozzle 45, it will eventually flow to the filter screen 48, and through the filtration of the filter screen 48, some dust and impurities are filtered out, and then the cleaning liquid enters the water tank 47 and is recovered, and can be recycled later. Finally, when the screw slider 33 returns to the initial position, the normally closed push switch 43 is pushed by the pressure rod 42, thereby turning off the water pump 41 and stopping the device.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
