DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0031] This invention discloses a street light that is self-powered in emergency situations, such as... Figures 1-11 As shown, the assembly includes a lamp post 100, a battery 200, a solar panel 800, a lighting component 300, a vertical telescopic component 500, and a lifting drive mechanism 400. The lamp post 100 is vertically positioned with its lower end fixed to the ground. The battery 200 is installed internally at the lower part of the lamp post 100. The solar panel 800 is installed at the upper end of the lamp post 100 and is electrically connected to the battery 200. The lighting component 300 is movably mounted on the lamp post 100 and is installed at the upper end of the vertical telescopic component 500, which is installed on the outer surface of the lamp post 100. The lifting drive mechanism 400 is constructed within the lamp post 100 and is drively connected to either the lighting component 300 or the vertical telescopic component 500. The working principle and advantages of this invention are as follows: This invention supplies power to the lighting component 300 through a pre-existing power supply line. When the power supply line experiences a power outage, the battery 200 supplies power to the lighting component 300, ensuring that the lighting component 300 remains lit at night. When the power supply line is restored, the battery 200 disconnects. During the day, the solar panel 800 converts solar energy into electrical energy, which is then stored in the battery 200. Furthermore, a charging port 201 is installed on the lamp post 100, allowing for periodic charging of the battery 200 using an external power source. When maintaining the lighting component 300 and / or replacing advertising signs, this invention drives the lifting drive mechanism 400, causing it to descend via the vertical telescopic component 500. Once at the predetermined position, the operator performs the maintenance and / or advertising sign replacement work. After completion, the lifting drive mechanism 400 is activated, causing the lighting component 300 to return to its original position, and finally, the lifting drive mechanism 400 is locked. In summary, this invention can provide self-powered illumination in emergency situations, ensuring the stability of nighttime lighting, preventing traffic accidents caused by limited visibility, reducing the difficulty of replacing advertising signs, and avoiding the risks associated with working at heights.

[0032] As a preferred embodiment of the present invention, such as Figure 2 , 5As shown, the assembled lamp pole 100 comprises a vertical pole body 101, an anchoring seat 102 is configured at the lower end of the vertical pole body 101, and the anchoring seat 102 is connected and fixed together with a pre-buried foundation seat arranged on the roadside through a plurality of anchoring bolts. A vertical guide groove 103 is configured on the outer surface of the vertical pole body 101, and the inside of the vertical pole body 101 is a hollow chamber. The vertical telescopic assembly 500 of the embodiment comprises a vertical cover plate strip 501, a first U-shaped strip 502 and a second U-shaped strip 503. The vertical cover plate strip 501 is detachably installed at the lower position of the vertical guide groove 103, the lower end of the first U-shaped strip 502 is movably inserted into the vertical guide groove 103 through the upper end of the vertical cover plate strip 501, and the lower end of the second U-shaped strip 503 is movably inserted into the vertical guide groove 103 through the upper end of the first U-shaped strip 502.

[0033] As a preferred embodiment of the present application, as shown in Figures 2-6As shown, the lifting driving mechanism 400 comprises an assembling shell 401, a winding shaft 402, a steel wire rope 406, an operating hand wheel 404 and two protective buckle covers 403. The assembling shell 401 is configured at the lower part of the assembling lamp pole 100 and is 1.4-1.8 m away from the ground, so as to facilitate manual operation of the operator. The winding shaft 402 is rotatably installed in the assembling shell 401, the two protective buckle covers 403 are detachably connected to the two opposite side walls of the assembling shell 401, and the two protective buckle covers 403 cover the two ends of the winding shaft 402 respectively, and the operating hand wheel 404 is configured on one of the protective buckle covers 403. A plug-in rod 405 is coaxially configured on the operating hand wheel 404, the plug-in rod 405 is plug-in fixed in one end of the winding shaft 402, the steel wire rope 406 is wound on the winding shaft 402, and the two ends of the steel wire rope 406 are connected with the upper end of the second U-shaped strip 503 or the lighting assembly 300. The working principle and advantages of the embodiment are that: when the lighting assembly 300 is maintained or the advertising sign is replaced, the protective buckle cover 403 connected with the operating hand wheel 404 is detached from the assembling lamp pole 100, and the fixing relationship between the two is released; then, the operating hand wheel 404 is rotated to drive the winding shaft 402 to rotate, one end of the steel wire rope 406 is in an unwinding state and the other end of the steel wire rope 406 is in a winding state in the process of rotation of the winding shaft 402, so as to realize that the steel wire rope 406 directly or indirectly pulls the lighting assembly 300 to move downward in the vertical direction, at the same time, the vertical telescopic assembly 500 is correspondingly contracted; when the lighting assembly 300 is lowered to the low position, the operating hand wheel 404 is stopped, and then subsequent maintenance and other operations are performed. After the operation is completed, the operating hand wheel 404 is reversely rotated, so that the steel wire rope 406 pulls the lighting assembly 300 to move upward, at the same time, the vertical telescopic assembly 500 is gradually stretched, and when the lighting assembly 300 reaches the predetermined height, the protective buckle cover 403 is connected and fixed with the assembling lamp pole 100. The over-rope hole 104 is formed in the lower part of the assembling shell 401, and the guide rope wheel 407 is rotatably installed on the upper part of the vertical rod body 101. One end of the steel wire rope 406 passes through the hollow chamber of the vertical rod body 101 in the vertical direction, is guided through the guide rope wheel 407, and is connected with the lighting assembly 300; the other end of the steel wire rope 406 passes through the over-rope hole 104 and the vertical guide slot 103 in sequence and is connected with the lighting assembly 300. Thus, part of the steel wire rope 406 is located in the hollow chamber of the assembling lamp pole 100, and the other part of the steel wire rope 406 is located in the vertical guide slot 103 and is protected by the vertical telescopic assembly 500, so as to avoid that the steel wire rope 406 is exposed and is subjected to bumping, corrosion and the like, and the service life of the steel wire rope 406 is prolonged.

[0034] As a preferred embodiment of the present application, Figure 2 、 3As shown, the lighting assembly 300 comprises a connecting arm 301, an LED lighting lamp head 302 and a sliding seat 303. The LED lighting lamp head 302 is mounted at one end of the connecting arm 301, and the sliding seat 303 is configured at the other end of the connecting arm 301. The sliding seat 303 is slidingly assembled on the vertical pole body 101, and the sliding seat 303 is detachably connected with the second U-shaped strip 503. In order to improve the connection strength between the lighting assembly 300 and the assembled lamp pole 100, and to avoid relative movement between the lighting assembly 300 and the assembled lamp pole 100 under external force (such as wind force, rain and snow, etc.), the following measures are taken in the embodiment, for example, Figures 7-10 As shown, the upper end of the sliding seat 303 is symmetrically mounted with a limiting contact assembly 900, and a limiting body 700 is fixed at the upper end of the vertical pole body 101. The upper end of the limiting body 700 is connected with the solar panel 800. Each limiting contact assembly 900 is elastically inserted into the limiting body 700, and the conductive wire connected with the LED lighting lamp head 302 passes through the connecting arm 301 and the sliding seat 303 and is connected with each limiting contact assembly 900. The limiting contact assembly 900 of the embodiment not only limits the sliding seat 303 of the lighting assembly 300, but also has the function of double-contact conduction. When the sliding seat 303 is driven to move downward, the limiting contact assembly 900 is separated from the limiting body 700. At this time, the limiting contact assembly 900 is separated from the upper end of the limiting body 700, so that the lighting assembly 300 is powered off, to ensure the safety of subsequent work personnel work. When the limiting contact assembly 900 is completely assembled in the limiting body 700, at least one of the two limiting contact assemblies 900 is in complete contact with the upper end of the limiting body 700, thereby ensuring smooth conduction, achieving the effect of continuous power supply of the power supply line and / or the storage battery 200 for the lighting assembly 300.

[0035] As a preferred embodiment of the present application, as Figures 7-9As shown, the limiting contact assembly 900 comprises a vertical insertion pipe 901, a vertical insertion rod 902, a connecting spring 905, a connecting seat 903 and a top joint 904. The vertical insertion pipe 901 is fixedly installed at the upper end of the sliding seat 303, the lower end of the vertical insertion rod 902 is movably inserted into the upper end of the vertical insertion pipe 901, the connecting seat 903 is installed at the upper end of the vertical insertion rod 902, the connecting spring 905 is sleeved on the outer side of the vertical insertion rod 902, the two ends of the connecting spring 905 are connected with the vertical insertion pipe 901 and the connecting seat 903 respectively, and the top joint 904 is installed at the upper end of the connecting seat 903. Two first hinged rods 906 are symmetrically hinged on the sliding seat 303, two second hinged rods 907 are symmetrically hinged on the connecting seat 903, and the first hinged rod 906 is hinged with the corresponding second hinged rod 907. The limiting body 700 comprises a block body 701, two limiting cavities 702 are symmetrically arranged in the block body 701, two limiting grooves 703 are symmetrically arranged in each limiting cavity 702, and the ends of the first hinged rod 906 and the second hinged rod 907 hinged with each other are located in the corresponding limiting groove 703. A top joint hole 704 is arranged at the upper end of the limiting cavity 702, a conductive sheet 705 is installed at the upper end of the top joint hole 704, the upper end of the top joint 904 extends into the top joint hole 704 and contacts with the conductive sheet 705, and the conductive sheet 705 is electrically connected with the battery 200 and the solar panel 800 through the wire 706. The working principle and advantages of the embodiment are that when the control lifting drive mechanism 400 drives the sliding seat 303 to move downward, the limiting contact assembly 900 moves downward, in the process, the connecting spring 905 gradually extends from the compressed state, the hinge points of the first hinged rod 906 and the second hinged rod 907 hinged with each other gradually move towards the vertical insertion pipe 901, and the two are separated from the corresponding limiting groove 703, at the same time, the top joint 904 is separated from the conductive sheet 705, and the purpose of power failure is achieved; then, the limiting contact assembly 900 gradually leaves the limiting cavity 702. When the control lifting drive mechanism 400 drives the sliding seat 303 to move upward, the limiting contact assembly 900 moves upward, in the process, the limiting contact assembly 900 gradually extends into the limiting cavity 702; when the top joint 904 abuts against the conductive sheet 705, the vertical insertion rod 902 gradually inserts into the vertical insertion pipe 901 as the limiting contact assembly 900 continues to move upward, thereby the hinge points of the first hinged rod 906 and the second hinged rod 907 hinged with each other are extended and gradually fitted in the corresponding limiting groove 703, at this time, the connecting spring 905 is in the compressed energy storage state. Moreover, due to the action of the connecting spring 905, the top joint 904 is always in the state of elastically abutting against the conductive sheet 705, which has a very high buffering effect, ensures that the limiting contact assembly 900 and the conductive sheet 705 are always in an electrically connected state, and avoids the power failure of the lighting assembly 300 due to poor contact.

[0036] As a preferred embodiment of the present application, as shown in Figure 10 、 11 connecting ears 304 are symmetrically arranged on both sides of the sliding seat 303, and retractable hanging frames 600 are detachably installed on each connecting ear 304, and the two retractable hanging frames 600 are arranged on both sides of the lighting assembly 300 respectively, and the retractable hanging frames 600 are used for hanging advertising signs. The specific structure of the retractable hanging frame 600 in the embodiment is that the retractable hanging frame 600 comprises a first seat body 601, a second seat body 602, a cross-cut type telescopic frame body 603, a support rod 604 and a support pipe 605. Among them, the first seat body 601 and the second seat body 602 are arranged at intervals, and a connecting screw rod 608 is installed on the first seat body 601, the connecting screw rod 608 is screwed together with a fixed seat 606, the fixed seat 606 is fixed on the connecting ear 304 through a locking bolt 607, and a fastening nut 609 is screwed on the connecting screw rod 608. The cross-cut type telescopic frame body 603 in the embodiment is arranged between the first seat body 601 and the second seat body 602, and the two ends of the cross-cut type telescopic frame body 603 are connected with the first seat body 601 and the second seat body 602 respectively, the support rod 604 and the support pipe 605 are arranged below the cross-cut type telescopic frame body 603, one end of the support rod 604 is inserted into the support pipe 605, the ends of the support rod 604 and the support pipe 605 away from each other are connected with the first seat body 601 and the second seat body 602 respectively, and the insertion parts of the support rod 604 and the support pipe 605 are locked by locking screws. The distance between the first seat body 601 and the second seat body 602 can be adjusted by adjusting the insertion length of the support rod 604 and the support pipe 605 in the embodiment, so that the length of the cross-cut type telescopic frame body 603 changes accordingly, and different models of advertising signs can be fixed. Moreover, the angle between the first seat body 601 and the fixed seat 606 can be adjusted in the embodiment, so that the angle of the retractable hanging frame 600 changes, the hanging angle of the advertising signs, holiday lanterns and the like is adjusted, and the purposes of beauty, prominence, wind resistance reduction and the like are achieved.
