DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] The present invention discloses a street lamp based on self-power supply in emergency situations, such as Figure 1-11 As shown, it includes an assembled light pole 100, a battery 200, a solar panel 800, a lighting assembly 300, a vertical telescopic assembly 500 and a lifting drive mechanism 400. The assembled light pole 100 is vertically arranged, and its lower end is fixed on the ground. The battery 200 is installed at an internal position at the lower part of the assembled light pole 100. The solar panel 800 is installed at the upper end of the assembled light pole 100, and the solar panel 800 is electrically connected to the battery 200. The lighting assembly 300 of the present invention is movably assembled on the assembled light pole 100, and the lighting assembly 300 is installed at the upper end of the vertical telescopic assembly 500, and the vertical telescopic assembly 500 is installed on the outer surface of the assembled light pole 100; the lifting drive mechanism 400 is constructed in the assembled light pole 100, and the lifting drive mechanism 400 is transmission-connected with the lighting assembly 300 or the vertical telescopic assembly 500. The working principle and advantages of the present invention are as follows: the present invention supplies power to the lighting assembly 300 through the inherent power supply line. When the power supply line is out of power, the storage battery 200 supplies power to the lighting assembly 300 to ensure that the lighting assembly 300 is always in a lighting state at night; when the power supply line is restored, the storage battery 200 disconnects the power supply. During the day, the solar panel 800 converts solar energy into electrical energy, which is then stored by the storage battery 200; and a charging port 201 is installed on the assembly lamp pole 100, and the storage battery 200 can be regularly charged with an external power supply. When the present invention is performing maintenance of the lighting assembly 300 and / or replacement of the publicity sign, the lifting drive mechanism 400 is driven to move, so that the lighting assembly 300 is driven to descend through the vertical telescopic assembly 500. When reaching the predetermined position, the operator performs the maintenance of the lighting assembly 300 and / or the replacement of the publicity sign; after completion, the lifting drive mechanism 400 is driven to move, and the lighting assembly 300 is driven to return to its position, and finally the lifting drive mechanism 400 is locked. In summary, the present invention can be self-powered in emergency situations, ensuring the stability of nighttime lighting, preventing traffic accidents due to limited vision, reducing the difficulty of replacing promotional signs, and avoiding the risks caused by high-altitude operations.

[0032] As a preferred embodiment of the present invention, Figure 2 , 5As shown, the assembled lamp pole 100 includes a vertical rod body 101, and an anchor seat 102 is constructed at the lower end of the vertical rod body 101. The anchor seat 102 is connected and fixed to the pre-buried foundation seat set on the roadside by multiple anchor bolts. A vertical guide groove 103 is constructed on the outer surface of the vertical rod body 101, and the interior of the vertical rod body 101 is a hollow chamber. The vertical telescopic assembly 500 of this embodiment includes a vertical cover strip 501, a first U-shaped strip 502 and a second U-shaped strip 503. The vertical cover 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 strip 501, and the lower end of the second U-shaped strip 503 is movably inserted into the vertical guide groove 103 from the upper end of the first U-shaped strip 502.

[0033] As a preferred embodiment of the present invention, Figure 2-6As shown, the lifting drive mechanism 400 includes an assembly shell 401, a winch shaft 402, a steel wire rope 406, an operating hand wheel 404 and two protective buckle covers 403. The assembly shell 401 is constructed at the lower part of the assembly lamp pole 100 and is 1.4-1.8m above the ground for easy manual operation by operators. The winch shaft 402 is rotatably mounted in the assembly shell 401, and the two protective buckle covers 403 are detachably connected to the two opposite side walls of the assembly shell 401, and the two protective buckle covers 403 are respectively covered at both ends of the winch shaft 402, and the operating hand wheel 404 is constructed on one of the protective buckle covers 403. A plug-in rod 405 is coaxially constructed on the operating hand wheel 404, and the plug-in rod 405 is inserted and fixed in one end of the winch shaft 402. The wire rope 406 is wound on the winch shaft 402, and both ends of the wire rope 406 are connected to the upper end of the second U-shaped bar 503, or both ends of the wire rope 406 are connected to the lighting assembly 300. The working principle and advantage of this embodiment are as follows: when the lighting assembly 300 is maintained or the promotional sign is replaced, the protective buckle cover 403 connected to the operating hand wheel 404 is disassembled from the assembled lamp pole 100 to release the fixed relationship between the two; thereafter, the operating hand wheel 404 is rotated to drive the winch shaft 402 to rotate. During the rotation of the winch shaft 402, one end of the wire rope 406 is in an unwinding state, and the other end of the wire rope 406 is in a winding state, thereby enabling the wire rope 406 to directly or indirectly pull the lighting assembly 300 downward in the vertical direction. At the same time, the vertical telescopic assembly 500 contracts accordingly; when the lighting assembly 300 is lowered to a low position, the operating hand wheel 404 is stopped, and then subsequent maintenance operations are performed. After the operation is completed, the operating hand wheel 404 is rotated in the opposite direction, so that the steel wire rope 406 pulls the lighting assembly 300 upward to move, and the vertical telescopic assembly 500 gradually extends until the lighting assembly 300 reaches a predetermined height, and then the protective buckle cover 403 is connected and fixed to the assembly lamp pole 100. In this embodiment, a rope hole 104 is provided at the lower part of the assembly shell 401, and a guide rope wheel 407 is rotatably installed at 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 upward in the vertical direction, and is connected to the lighting assembly 300 after being guided by the guide rope wheel 407; the other end of the steel wire rope 406 passes through the rope hole 104 and the vertical guide groove 103 in sequence and is connected to the lighting assembly 300. As a result, part of the steel wire rope 406 is located in the hollow chamber of the lamp pole 100, and the other part is located in the vertical guide groove 103 and protected by the vertical telescopic assembly 500, thereby preventing the steel wire rope 406 from being exposed to the outside and being bumped, corroded, etc., and extending the service life of the steel wire rope 406.

[0034] As a preferred embodiment of the present invention, Figure 2 , 3As shown, the lighting assembly 300 includes a connecting arm 301, an LED lighting lamp head 302 and a sliding seat 303. The LED lighting lamp head 302 is installed at one end of the connecting arm 301, and the sliding seat 303 is constructed at the other end of the connecting arm 301. The sliding seat 303 is slidably assembled on the vertical rod body 101, and the sliding seat 303 is detachably connected to the second U-shaped bar 503. In order to improve the connection strength between the lighting assembly 300 and the assembled lamp pole 100, and to prevent the lighting assembly 300 from moving relative to the assembled lamp pole 100 under external forces (such as wind, rain, snow, etc.), the measures taken in this embodiment are as follows: Figure 7-10 As shown, the upper end of the sliding seat 303 is symmetrically mounted with a restricting contact assembly 900, the upper end of the vertical rod 101 is fixed with a restricting body 700, the upper end of the restricting body 700 is connected to the solar panel 800, each restricting contact assembly 900 is elastically inserted into the restricting body 700, and the conductive wire connecting the LED lighting lamp head 302 passes through the connecting arm 301 and the sliding seat 303 to connect with each restricting contact assembly 900. The restricting contact assembly 900 of this embodiment not only serves to restrict the sliding seat 303 of the lighting assembly 300, but also serves as a double contact conductive function, that is, when the sliding seat 303 is driven to move downward, causing the restricting contact assembly 900 to detach from the restricting body 700, at this time, the restricting contact assembly 900 is disengaged from the upper end of the restricting body 700, so that the lighting assembly 300 is powered off to ensure the safety of subsequent operations of the staff. When the restricting contact assembly 900 is fully assembled in the restricting body 700, at least one of the two restricting contact assemblies 900 is in full contact with the upper end of the restricting body 700, thereby ensuring smooth conduction and achieving the effect that the power supply line and / or the battery 200 continuously supplies power to the lighting assembly 300.

[0035] As a preferred embodiment of the present invention, Figure 7-9As shown, the restrictive contact assembly 900 includes a vertical insert tube 901, a vertical insert rod 902, a connecting spring 905, a connecting seat 903 and a top joint 904. The vertical insert tube 901 is fixedly mounted on the upper end of the sliding seat 303, the lower end of the vertical insert rod 902 is movably inserted by the upper end of the vertical insert tube 901, the connecting seat 903 is mounted on the upper end of the vertical insert rod 902, the connecting spring 905 is sleeved outside the vertical insert rod 902, the two ends of the connecting spring 905 are respectively connected to the vertical insert tube 901 and the connecting seat 903, and the top joint 904 is mounted on the upper end of the connecting seat 903. In this embodiment, two first hinged rods 906 are symmetrically hinged on the sliding seat 303, and two second hinged rods 907 are symmetrically hinged on the connecting seat 903, and the first hinged rod 906 and the corresponding second hinged rod 907 are hinged together. The limiting body 700 of this embodiment includes a block body 701, in which two limiting cavities 702 are symmetrically constructed, and in each limiting cavity 702, two limiting grooves 703 are symmetrically constructed, and the ends of the first hinge rod 906 and the second hinge rod 907, which are hinged to each other, are located in the corresponding limiting grooves 703. A top connection hole 704 is constructed at the upper end of the limiting cavity 702, and a conductive sheet 705 is installed at the upper end of the top connection hole 704. The upper end of the top connection 904 extends into the top connection hole 704 and contacts the conductive sheet 705, and the conductive sheet 705 is electrically connected to the storage battery 200 and the solar panel 800 through the wire 706. The working principle and advantage of this embodiment are as follows: when the lifting drive mechanism 400 is controlled to drive the sliding seat 303 to move downward, the restricting contact assembly 900 moves downward accordingly. During this process, the connecting spring 905 gradually stretches from a compressed state, so that the hinge points of the first hinged rod 906 and the second hinged rod 907, which are hinged to each other, gradually move toward the vertical insert 901, and the two are disengaged from the corresponding restricting grooves 703. At the same time, the top joint 904 is disengaged from the conductive sheet 705, thereby achieving the purpose of power off. Afterwards, the restricting contact assembly 900 gradually leaves the restricting cavity 702. When the lifting drive mechanism 400 is controlled to drive the sliding seat 303 to move upward, the restrictive contact assembly 900 moves upward accordingly. In this process, the restrictive contact assembly 900 gradually extends into the restricting cavity 702. When the top joint 904 abuts against the conductive sheet 705, as the restrictive contact assembly 900 continues to be driven upward, the vertical insertion rod 902 is gradually inserted into the vertical insertion tube 901, and then the hinge points of the first hinge rod 906 and the second hinge rod 907 that are hinged to each other are stretched outward and gradually fit into the corresponding restricting groove 703. At this time, the connecting spring 905 is in a compressed energy storage state. In addition, due to the action of the connecting spring 905, the top joint 904 is always in a state of elastically abutting against the conductive sheet 705. While having a very high buffering effect, it ensures that the restrictive contact assembly 900 and the conductive sheet 705 are always in an electrically connected state, avoiding the lighting assembly 300 from being powered off due to poor contact.

[0036] As a preferred embodiment of the present invention, Fig.10 , 11 As shown, connecting ears 304 are symmetrically constructed on both sides of the sliding seat 303, and a telescopic suspension frame 600 is detachably installed on each connecting ear 304, and the two telescopic suspension frames 600 are respectively arranged on both sides of the lighting assembly 300, and the telescopic suspension frame 600 is used to hang a promotional sign. The specific structure of the telescopic suspension frame 600 in this embodiment is that the telescopic suspension frame 600 includes a first seat body 601, a second seat body 602, a cross-type telescopic frame body 603, a support rod 604 and a support tube 605. Among them, the first seat body 601 and the second seat body 602 are arranged at intervals, and a connecting screw 608 is installed on the first seat body 601, and the connecting screw 608 is threadedly connected to the fixing seat 606, and the fixing seat 606 is fixed to the connecting ear 304 by a locking bolt 607, and a fastening nut 609 is threadedly connected to the connecting screw 608. The cross-scissor type telescopic frame body 603 of the present embodiment is arranged between the first seat body 601 and the second seat body 602, and the two ends of the cross-scissor type telescopic frame body 603 are respectively connected to the first seat body 601 and the second seat body 602, and the support rod 604 and the support tube 605 are both arranged below the cross-scissor type telescopic frame body 603, one end of the support rod 604 is inserted into the support tube 605, and the ends of the support rod 604 and the support tube 605 that are away from each other are respectively connected to the first seat body 601 and the second seat body 602, and the parts where the support rod 604 and the support tube 605 are inserted into each other are locked by locking screws. In this embodiment, the distance between the first seat body 601 and the second seat body 602 can be adjusted by adjusting the connection length of the support rod 604 and the support tube 605, so that the length of the scissor-type telescopic frame 603 changes accordingly, thereby achieving the fixation of different types of promotional signs; and in this embodiment, the angle between the first seat body 601 and the fixing seat 606 can be adjusted, so that the angle of the telescopic suspension frame 600 changes, thereby achieving the adjustment of the hanging angle of promotional signs, holiday lanterns, etc., to achieve the purposes of beauty, eye-catchingness, and reduced wind resistance.
