[0002] Security alarm street lights are intelligent devices that combine lighting and security functions. They not only provide lighting at night, but also sound an alarm when abnormal conditions are detected, enhancing public safety. When the built-in sensors in the street lights detect abnormal conditions, such as vibration, sound or human movement, the alarm device will be automatically triggered to sound and light alarms to remind people around to pay attention to safety.

[0003] After searching, the patent technology with announcement number CN212057031U discloses a street lamp with security monitoring function, including a lamp post, a lamp post welded below the outer surface of the lamp post, a lighting device arranged on one side of the lamp post, a No. 4 support block arranged on one side of the lamp post, and the No. 4 support block is welded above the outer surface of the base, and a No. 3 support block is welded at the end of one side of the outer surface of the No. 4 support block, and a bolt rod is connected to the inside of the No. 3 support block. In the device, a bolt groove is opened inside the No. 3 support block to ensure the rotation inside the No. 3 support block. When the monitoring equipment needs to be repaired or replaced, the bolt rod can be rotated to make the No. 1 support block welded on the upper surface of the No. 2 support block and the fixed block move down together, and the monitoring equipment connected to the fixed block will also move down from the top. When it moves down to a suitable position, stop rotating the bolt rod, and the maintenance personnel can repair or replace the monitoring equipment. However, the street lamp can only realize the lifting function of the monitoring equipment, and the function is relatively single. In addition, the power supply mode of the street lamp adopts the municipal circuit power supply, which increases the power cost.

A lever 74 is fixed to one end of the U-shaped clamp 71, and a fixing rod 75 is fixed to the end of the lever 74 away from the U-shaped clamp 71. When the slider 21 rises to the end position of the top of the external thread 32, the monitoring camera 23 no longer continues to slide upward. During this process, the top plate 24 on the slider 21 can push the lever 74, so that the U-shaped clamp 71 rotates clockwise with the rotating shaft 73 as the rotation fulcrum, thereby driving the U-shaped clamp 71 to flip downward. Under the limitation of the limit shaft 67 by the bayonet 72, the sliding sleeve 61 is pushed to stretch the second spring 63 and slide downward outside the driven rod 53.

[0040] See also Fig. 9 The lighting assembly 4 includes a lamp holder 41, which is fixed to one side of the top of the lamp holder 1. A lamp board 42 is embedded in the bottom of the lamp holder 41.

The lamp board 42 is made of acrylic material and has good light transmittance and high temperature resistance.

[0041] See also Fig.10The cleaning assembly 8 includes a slide plate 81, and both ends of the slide plate 81 are slidably arranged in the slide grooves 43 on both sides of the lamp holder 41. Connecting blocks 82 are fixed at both ends of the slide plate 81. The connecting blocks 82 are slidably arranged outside the guide rod 44 and conflict with the first spring 45. A traction rope 83 is fixed at one end of the connecting block 82. The end of the traction rope 83 away from the connecting block 82 passes around the fixed pulley 47 and is fixed to the end of the fixed rod 75. A scraping member 84 is provided on the side of the slide plate 81 facing the lamp board 42. During the clockwise rotation of the U-shaped clip 71, the traction rope 83 can be pulled by the fixed rod 75 to drive the connecting block 82 to compress the first spring 45 and slide on the guide rod 44 toward the lamp holder 1, thereby driving the slide plate 81 to move synchronously under the limit of the slide groove 43.

[0042] See also Fig.11 The scraping member 84 includes a scraper 841, both ends of which are hinged with hinge seats 842 fixed on the slide 81, a clamping block 843 is fixed on the back of the scraper 841, the clamping block 843 is elastically connected to the slide 81 through a third spring 844, a cotton swab 845 is fixedly embedded on the clamping block 843, and the side of the scraper 841 facing away from the clamping block 843 is an arc surface. When the slide 81 slides toward the lamp holder 1, the clamping block 843 is affected by the third spring 844. The elastic force of the cotton swab 845 makes it fit the lower surface of the lamp board 42. The friction between the cotton swab 845 and the lamp board 42 can make the scraper 841 tend to rotate counterclockwise under the hinge action of the hinge seat 842 and fit the lower surface of the lamp board 42. The blade of the scraper 841 can scrape off the dirt attached to the lower surface of the lamp board 42, and the scraped dirt is discharged through the curved surface of the scraper. At the same time, the scraped surface is wiped to ensure the cleanliness of the lamp board 42.

[0043] The working principle and use process of the present invention are as follows: the driving form of the transmission rod 31 in the present invention can be any one of manual rotation or motor-driven rotation. When the installation rod 22 needs to be maintained, the transmission rod 31 can be rotated, and the outer thread 32 of the transmission rod 31 cooperates with the thread of the slider 21, and the upper limit groove 11 of the lamp frame 1 guides the slider 21 to slide, so that the slider 21 can be driven to descend, thereby lowering the height of the monitoring camera 23 to facilitate maintenance of the monitoring camera 23. After the maintenance is completed, the transmission rod 31 is reversed to raise the height of the monitoring camera 23 to the initial position;

[0044] When the slider 21 rises to the end position of the top of the external thread 32, the monitoring camera 23 no longer slides upward. During this process, the top plate 24 on the slider 21 can push the lever 74, so that the U-shaped clip 71 rotates clockwise with the rotating shaft 73 as the rotation fulcrum, thereby driving the U-shaped clip 71 to flip downward. Under the limitation of the limit shaft 67 by the bayonet 72, the sliding sleeve 61 is pushed to stretch the second spring 63 and slide downward outside the driven rod 53 until the second bevel tooth surface 65 on the bottom surface of the second pressure plate 64 contacts the first bevel tooth surface 34 on the top surface of the first pressure plate 33. Through the rotational engagement of the second bevel tooth surface 65 and the first bevel tooth surface 34, the sliding sleeve 61 can be driven to rotate. Under the sliding cooperation between the sliding sleeve 61 and the guide strip 55, the driven rod 53 is driven to rotate synchronously, thereby adjusting the position of the photovoltaic panel 52 so that the photovoltaic panel 52 is oriented to a suitable sunny side.

[0045] During the rotation of the U-shaped clip 71, the fixing rod 75 can pull the traction rope 83, drive the connecting block 82 to compress the first spring 45 and slide on the guide rod 44 toward the lamp holder 1, thereby driving the slide plate 81 to move synchronously under the limit of the slide groove 43. During this process, the block 843 is subjected to the elastic force of the third spring 844, so that the cotton swab 845 is attached to the lower surface of the lamp board 42. Through the friction between the cotton swab 845 and the lamp board 42, the scraper 841 tends to rotate counterclockwise and fits the lower surface of the lamp board 42 under the hinged action of the hinge seat 842. The blade of the scraper 841 can scrape off the dirt attached to the lower surface of the lamp board 42, and the scraped dirt is discharged through the curved surface of the scraper. At the same time, the scraped surface is wiped to ensure the cleanliness of the lamp board 42.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
