[0003] Existing smart street lights are the most common municipal equipment in the development of smart cities. In terms of energy utilization, existing smart street lights usually use solar energy and wind energy to generate electricity using natural resources for street lights. However, the power generation environment is limited, especially in rainy weather, the amount of electricity generated is not enough for use. Therefore, it is necessary to improve the existing smart street lights. Summary of the invention
[0004] The object of the present invention is to provide a height-adjustable intelligent street lamp to solve the problems mentioned in the above background technology.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] A height-adjustable smart street lamp comprises a lamp post, a fixing seat, a lamp pole and a lamp holder; the fixing seat is fixedly installed at the lower end of the vertical lamp post, the street lamp is fixed to the ground through the fixing seat, a lamp pole inclined upward is fixedly installed on the top of the lamp post, and a lamp holder for illuminating downward is installed on the upper end of the lamp post; a rainwater collection cover with an opening facing vertically upward is fixedly installed on the top of the lamp post; the lamp post is a hollow structure, and a drainage cavity is arranged inside, the top of the drainage cavity is connected with the rainwater collection cover, rainwater collected in the rainwater collection cover enters the drainage cavity, flows downward in the drainage cavity, and flows into the bottom of the drainage cavity corresponding to the rainwater collected in the rainwater collection cover. A drainage port is provided on the side wall of the lamp post, and rainwater falling from above is discharged outward from the drainage port; a horizontal water conservancy power generation rotating roller is arranged in the middle of the lower water chamber, and the central axis of the water conservancy power generation rotating roller is rotatably connected to the inner wall of the lower water chamber through a bearing, and a plurality of water conservancy power generation blades along the radial direction of the water conservancy power generation rotating roller are fixedly installed on the side wall of the water conservancy power generation rotating roller, and the water conservancy power generation blades are evenly distributed, and an inclined guide plate is fixedly installed on the top of the lower water chamber, and a drainage port that penetrates to the bottom of the guide plate is provided at the lower end of the guide plate, so that rainwater falling from above enters the drainage port, so that more water falls and the water conservancy The power generation blades are in contact with each other, and the water falling from the water outlet is located on one side of the central axis of the hydropower generation rotating roller, which pushes the hydropower generation blades to rotate downward from this side; a transmission gear is coaxially fixedly installed on the hydropower generation rotating roller, and a transmission chain that transmits power downward is wound around the transmission gear, and the lower end of the transmission chain is meshed and connected with a one-way drive flywheel mechanism, and a transmission shaft is coaxially installed on the center of the one-way drive flywheel mechanism. The one-way drive flywheel mechanism has the function of driving the transmission shaft to rotate in one direction, that is, when the water falling from above drives the hydropower generation rotating roller to rotate, the power is transmitted to the transmission shaft, driving the transmission shaft to rotate, and the transmission shaft itself The rotation of the lamp post cannot transmit power to the hydropower rotating roller, so that power can only be transmitted from the hydropower rotating roller to the transmission shaft, so that the horizontal push power can be transmitted to the transmission shaft, so that the transmission shaft rotates; the two ends of the transmission shaft extend out from the lamp post through bearings, and one end of the transmission shaft is coaxially fixedly connected to the generator, driving the generator to rotate, and generating electricity by the rotation of the transmission shaft; the other end of the transmission shaft is coaxially connected to a wind power impeller located outside the lamp post, and the wind power impeller and the transmission shaft are also driven by a one-way drive flywheel mechanism to transmit wind power to the transmission shaft. The wind power impeller is blown by the external wind force, driving the transmission shaft to rotate, realizing wind power generation.
[0007] Furthermore: the cross-sectional area of the rainwater collection cover is greater than the cross-sectional area of the lamp post, so that the rainwater collection cover can collect more rainwater.
[0008] Furthermore: during the rotation of the hydropower generation blade, the distance between the end and the inner wall of the lower water chamber is less than 5 mm, so that the water falling from above can contact the hydropower generation blade, push the hydropower generation blade to move, and thus rotate the hydropower generation rotating roller.
[0009] Furthermore: a collecting bucket with an upward opening is arranged directly below the drain outlet, a supporting shaft is horizontally penetrated through the lower part of the collecting bucket, and both ends of the supporting shaft are rotatably connected to the inner wall of the drain chamber through bearings. The collecting bucket is deflected to pour the water inside onto the top of the other side of the hydropower generation rotating roller opposite to the drain outlet, and pours from the other side of the hydropower generation rotating roller, pushing the hydropower generation rotating roller to rotate; a limiting block fixed to a side wall of the adjacent drain chamber is arranged between the collecting bucket and the side wall, so that the collecting bucket is located at the highest position, supporting the collecting bucket to remain stationary, and ensuring that rainwater falling from the drain outlet enters the collecting bucket; in the limiting block A steel cable is fixedly connected to the side wall of the collecting bucket corresponding to the block. The steel cable passes through the side wall of the lamp post and goes downward through the guide wheel. A reset counterweight block is fixedly installed on the lower end of the steel cable. The collecting bucket is pulled close to the limit block by the reset counterweight block to keep its position fixed. When a lot of rainwater is collected inside, the pulling force generated by the rotation of the collecting bucket on the steel cable is greater than the gravity of the reset counterweight block. The collecting bucket cannot be pulled and keeps its position fixed, so that the collecting bucket rotates around the supporting shaft and pours out the rainwater inside after tilting. After pouring out the rainwater, the collecting bucket is pulled back to its original position under the action of the gravity of the reset counterweight block, so that the collecting bucket collects rainwater upward again.
[0010] Furthermore, the area of the opening of the collection barrel is larger than the area of the bottom. After the collection barrel is filled with rainwater, the weight on the top is larger, which causes the collection barrel to deflect, thereby pouring out the rainwater collected inside.
[0011] Furthermore: the material of the limit block is rubber.
[0012] Furthermore: a fixing plate is horizontally fixed on the inner wall of the lower water cavity on the same side as the limit block and is arranged directly below the collecting barrel. One end of the fixing plate is fixedly connected to the inner wall of the lower water cavity, and the other end of the fixing plate opposite to it is located directly above the transmission shaft, so that rainwater falling from above and not entering the collecting barrel flows along the upper surface of the fixing plate, avoiding direct falling and hindering the rotation of the hydropower generation roller; a plurality of vertical shock-absorbing springs are fixedly installed on the end of the fixing plate above the transmission shaft, which contact the top of the shock-absorbing spring when the collecting barrel rotates to the fixing plate, compressing the collecting barrel, so that the shock-absorbing spring can be used to quickly reset the collecting barrel after the water is poured out.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention transmits the power generated by wind and water to the transmission shaft, which drives the generator to rotate, generates electric power and stores it for use in street lamps, so that the street lamps can adapt to various external environments to generate electricity, thereby reducing the use cost of the street lamps; when hydropower generation is utilized, the rainwater collected above is intermittently poured downwards, and the more collected rainwater is utilized to drive the hydropower generation rotating roller to rotate, thereby increasing the rotation speed of the hydropower generation rotating roller and improving the power generation efficiency.

During the rotation of the hydropower generation blades 8, the distance between the end and the inner wall of the lower water chamber 14 is less than 5 mm, so that the water falling from above can contact the hydropower generation blades 8, pushing the hydropower generation blades 8 to move, thereby rotating the hydropower generation rotating roller 7; an inclined guide plate 16 is fixedly installed on the top of the lower water chamber 14, and a lower water outlet 17 penetrating to the bottom of the guide plate 16 is provided at the lower end of the guide plate 16, so that rainwater falling from above enters the lower water outlet 17, so that more water falls at the same time and contacts the hydropower generation blades 8, and the water falling from the lower water outlet 17 is located on one side of the central axis of the hydropower generation rotating roller 7, and pushes the hydropower generation blades 8 to rotate downward from this side.
[0021] A transmission gear 9 is coaxially fixedly installed on the hydropower generation rotating roller 7, and a transmission chain 10 for transmitting power downward is wound around the transmission gear 9. The lower end of the transmission chain 10 is meshed and connected with a one-way drive flywheel mechanism 11, and a transmission shaft 12 is coaxially installed on the center of the one-way drive flywheel mechanism 11. The one-way drive flywheel mechanism 11 has the function of driving the transmission shaft 12 to rotate in one direction, that is, when the water falling from above drives the hydropower generation rotating roller 7 to rotate, the power is transmitted to the transmission shaft 12, driving the transmission shaft 12 to rotate, and the rotation of the transmission shaft 12 itself cannot transmit power to the hydropower generation rotating roller 7, so that the power can only be transmitted from the hydropower generation rotating roller 7 to the transmission shaft 12, so that the horizontal driving power can be transmitted to the transmission shaft 12, so that the transmission shaft 12 rotates.
[0022] The two ends of the transmission shaft 12 extend out of the lamp post 1 through bearings, and one end of the transmission shaft 12 is coaxially fixedly connected to the generator 13, driving the generator 13 to rotate, and generating electricity by the rotation of the transmission shaft 12; the other end of the transmission shaft 12 is coaxially connected to the wind power impeller 6 located outside the lamp post 1, and the wind power impeller 6 and the transmission shaft 12 are also driven by a one-way drive flywheel mechanism 11 to transmit wind power to the transmission shaft 12. The wind power impeller 6 is driven by the external wind force, driving the transmission shaft 12 to rotate, and generating wind power.
[0023] Example 2
[0024] On the basis of Example 1, a collecting bucket 18 with an opening facing upward is provided directly below the drain port 17, and a supporting shaft 22 is horizontally penetrated through the lower part of the collecting bucket 18, and both ends of the supporting shaft 22 are rotatably connected to the inner wall of the lower water chamber 14 through bearings. Preferably, the area of the opening of the collecting bucket 18 is larger than the area of the bottom. After the collecting bucket 18 is filled with rainwater, the weight on the top is larger, so that the collecting bucket 18 is deflected, thereby pouring out the rainwater collected inside. The deflection of the collecting bucket 18 pours the water inside above the other side of the hydropower generation rotating roller 7 opposite to the drain port 17, and falls from the other side of the hydropower generation rotating roller 7, pushing the hydropower generation rotating roller 7 to rotate; a limiting block 19 fixed to a side wall of the adjacent lower water chamber 14 is provided between the collecting bucket 18 and the side wall, and the material of the limiting block 19 is rubber, so that the collecting bucket 18 is located at the highest The position of the collecting barrel 18 is supported, and the position of the collecting barrel 18 is fixed, so as to ensure that the rainwater falling from the drain port 17 enters the collecting barrel 18; a steel cable 20 is fixedly connected to the side wall of the collecting barrel 18 corresponding to the limit block 19, and the steel cable 20 passes through the side wall of the lamp post 1 and goes downward through the guide wheel. A reset counterweight block 21 is fixedly installed on the lower end of the steel cable 20, and the collecting barrel 18 is pulled close to the limit block 19 by the reset counterweight block 21 to keep the position fixed; when a lot of rainwater is collected inside, the pulling force generated by the rotation of the collecting barrel 18 on the steel cable 20 is greater than the gravity of the reset counterweight block 21, and the collecting barrel 18 cannot be pulled and keeps the position fixed, so that the collecting barrel 18 rotates around the supporting shaft 22, and the rainwater inside is poured out after tilting. After pouring out the rainwater, the collecting barrel 18 is pulled back to its original position under the action of the gravity of the reset counterweight block 21, so that the collecting barrel 18 collects rainwater upward again.

[0026] When in use, the street lamp is located outdoors and is illuminated by the lamp head 4; when the external environment is windy, the wind drives the transmission shaft 12 to rotate, causing the generator 13 to rotate to generate electricity; in a rainy environment, the rainwater collection cover 5 collects rainwater, and flows downward along the guide plate 16, falls from the drain port 17, and is collected in the internal collection bucket 18. After collecting to a certain extent, the collection bucket 18 rotates to pour out the rainwater inside, and the poured rainwater drives the hydropower generation rotating roller 7 below to rotate, and then transmits power to the transmission shaft 12, realizing two ways of driving power generation, and the two ways both independently transmit power to the generator 13 for power generation.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
