Description

Technical Field

[0001] The utility model belongs to the technical field of energy-saving street lamps, and in particular relates to a light-rain complementary double energy-saving street lamp. Background Art

[0002] Traditional new energy street lamps generally use solar power generation, that is, photovoltaic panels are used to convert solar energy into electricity to power street lamps. In some rainy weather, although photovoltaic panels can continue to generate electricity, the lack of sunlight on rainy days will reduce the power generation efficiency of photovoltaic panels, especially in rainy areas, which will lead to the inability to guarantee the power generation and make it difficult to use them stably and reliably. For this reason, some street lamps that combine light and rain for power generation have been proposed in the prior art, that is, on the basis of solar power generation, rainwater is collected on rainy days and used to flush the runner of the water turbine generator to achieve hydropower generation, making up for the lack of solar power generation efficiency on rainy days. In actual applications, some layout structures set the rain collector higher than the photovoltaic panel, so that in the process of photovoltaic panel chasing light and rotating, it is easy to block part of the light, affecting the efficiency of the photovoltaic panel. If the rain collector is set lower, although it will not affect the efficiency of the photovoltaic panel, the potential energy of the rainwater will decrease when it flows downward to the runner of the water turbine generator after being collected, which will also reduce the efficiency of the water turbine generator.

[0024] like Figure 1-Figure 2 As shown, the utility model provides a light-rain complementary dual energy-saving street lamp, comprising a lamp pole 1, a lamp 2, a hydro-generator 3, a rain collector 4, a photovoltaic panel 5 and a battery. The lamp pole 1 is a supporting structure of the street lamp as a whole, and the lamp 2 is arranged on the lamp pole 1, specifically, on a support rod extending from the top side of the lamp pole 1. The hydro-generator 3 is arranged at the lower end of the lamp pole 1. The rain collector 4 is arranged at the top of the lamp pole 1, and the top of the rain collector 4 is open and can receive rainwater, and the bottom of the rain collector 4 is connected with a diversion channel, and the end of the diversion channel is arranged toward the runner 31 of the hydro-generator 3. The rainwater collected by the rain collector 4 flows downward along the diversion channel to flush the runner 31 of the hydro-generator 3, so that the hydro-generator 3 can generate electricity. The photovoltaic panel 5 is centrally arranged on the top of the rain collector 4, and the size of the top of the rain collector 4 is larger than the size of the photovoltaic panel 5. A gap is formed between the top edge of the rain collector 4 and the edge of the photovoltaic panel 5 for rainwater to flow into the inside of the rain collector 4. The storage battery is used to store the electric energy converted by the hydro-generator 3 and the photovoltaic panel 5, and is electrically connected to the lamp 2 to power the lamp 2. The storage battery is specifically arranged on the lamp pole 1. Specifically, in the utility model, the photovoltaic panel 5 is equipped with a solar power controller electrically connected to the storage battery. Under normal operation, the photovoltaic panel 5 continuously converts solar energy into electric energy during the day and stores it in the storage battery. In order to ensure the stability of the electric energy converted and output by the hydro-generator 3, a rectifier current and a voltage stabilizing module can be provided. The electric energy converted by the hydro-generator 3 is stored in the storage battery after passing through the rectifier circuit and the voltage stabilizing module.

[0025] The utility model converts solar energy into electrical energy through the photovoltaic panel 5 during the day, collects rainwater through the rain collector 4 on rainy days and uses the collected rainwater to flush the water turbine generator 3 to generate electricity, thereby compensating for the low power generation efficiency of the photovoltaic panel 5 on rainy days, effectively utilizing solar energy and rainwater energy, ensuring that the battery can continuously and stably supply power, being particularly suitable for areas with rainy weather, and having good energy-saving and emission-reduction effects. By centrally arranging the photovoltaic panel 5 on the top of the rain collector 4, the photovoltaic panel 5 will not be blocked by other structural components on the street lamp whether it is in a fixed state or in a rotating state, thereby effectively ensuring the efficiency of the photovoltaic panel 5, and the rainwater falling between the rain collector 4 and the photovoltaic panel 5 can directly enter the rain collector 4, and the rainwater falling on the photovoltaic panel 5 can also fall into the rain collector 4 along the edge of the photovoltaic panel 5, so the rain collector 4 can still play the role of receiving rainwater normally and effectively, and this arrangement method makes the rain collector 4 neither block the light of the photovoltaic panel 5 nor be in a higher position, so that the potential energy of the collected rainwater when it impacts the impeller 31 of the hydro-generator 3 is greater, and the rotation speed of the impeller 31 is faster, so that the power generation efficiency of the photovoltaic panel can be guaranteed, and the power generation efficiency of the hydro-generator can be further improved, thereby fully improving the overall power generation efficiency. Compared with the method of using a support rod to extend the photovoltaic panel 5 to one side of the rain collector 4, or using a support rod to extend the rain collector 4 to one side of the photovoltaic panel 5, the rain collector 4 and the photovoltaic panel 5 of the utility model are approximately centered on the top of the lamp pole 1, which provides better support for the rain collector 4 and the photovoltaic panel 5.

[0026] Preferably, the top size of the rain collector 4 is larger than 1.5 times that of the photovoltaic panel 5, that is, the width and length of the rain collector 4 are larger than 1.5 times that of the photovoltaic panel 5, ensuring that there is enough space between the edge of the rain collector 4 and the edge of the photovoltaic panel 5 for rainwater to fall into.

[0027] A filter plate 41 is provided on the top of the rain collector 4, and the photovoltaic panel 5 is centrally arranged on the filter plate 41. The filter plate 41 is specifically a plate structure with holes, which can be used to intercept branches, fallen leaves and other debris on one hand, to prevent branches, fallen leaves and other debris from falling into the bottom of the rain collector 4 and causing blockage problems, and on the other hand, the filter plate 41 also serves as a mounting seat for the photovoltaic panel 5, eliminating the need for an additional mounting bracket.

[0028] The utility model further includes a steering mechanism 6, which is arranged on the top of the lamp pole 1, and the rain collector 4 is arranged on the output end of the steering mechanism 6. In the utility model, since the photovoltaic panel 5 is arranged on the filter plate 41 on the top of the rain collector 4, the orientation angle of the photovoltaic panel 5 can be adjusted by changing the orientation angle of the rain collector 4 through the steering mechanism 6, so that it can be kept at an ideal angle for being irradiated by light. In addition, during the angle change process, the top of the rain collector 4 will be tilted, so that branches, fallen leaves and other debris that fall on the filter plate 41 will slide off, avoiding excessive accumulation of debris and affecting the rainwater collection efficiency of the rain collector 4. Therefore, based on this setting mode, the orientation angle adjustment of the photovoltaic panel 5 and the cleaning of debris on the top filter plate 41 of the rain collector 4 can be achieved through the same steering mechanism 6. In addition, since the ideal tilt angle of the photovoltaic panel 5 is generally 15°-35°, within this tilt angle range, the rain collector 4 can still effectively collect rainwater normally on rainy days. The steering mechanism 6 can be a motor, a steering gear or a combination of two or more motors, or other adjustment mechanisms that can drive the rain collector 4 and the photovoltaic panel 5 to change their angles. When the steering mechanism 6 is a motor, the motor's shaft is its output end. When the steering mechanism 6 is a combination of two motors, one of the motors is set on the top of the lamp pole, and its shaft is set horizontally, and the other motor is set on the shaft of the previous motor, and its shaft is set vertically. The rain collector 4 is set on the shaft of the motor with the shaft set vertically, so as to realize the horizontal rotation and pitch angle adjustment of the rain collector 4 and the photovoltaic panel 5. The steering mechanism 6 is electrically connected to the battery and powered by the battery.

[0029] In one embodiment of the present invention, the angles of the rain collector 4 and the photovoltaic panel 5 are pre-adjusted by the steering mechanism 6 according to the specific area and position, and the angles do not change during operation.

[0030] In another embodiment of the utility model, a light intensity detection unit and a single chip microcomputer are also included. The light intensity detection unit is arranged on the photovoltaic panel 5. The light intensity detection unit is specifically a photoresistor. The photoresistor preferably has five, four of which are arranged on the four sides of the photovoltaic panel 5, and another photoresistor is arranged in the middle of the photovoltaic panel 5, and the steering mechanism 6 and all photosensitive electrical groups are electrically connected or signal-connected to the single chip microcomputer. When the sunlight is vertically irradiated on the photovoltaic panel 5, the four photoresistors located on the four sides are almost the same in terms of light intensity. As time goes by, the sunlight will gradually deviate from the center position, causing the light intensity irradiated on each photoresistor to change, its resistance value will also change, and the voltage value at both ends of the photoresistor will also change. The single chip microcomputer reads the voltage value at both ends of the photoresistors on the four sides, and according to the difference between the voltage values, drives the steering mechanism 6 to make corresponding adjustments to achieve the light chasing adjustment of the photovoltaic panel 5. The specific adjustment and control principles are prior art and will not be repeated here.

[0031] In one embodiment of the diversion channel, the utility model further comprises a flexible tube 7 and a diversion tube 8, one end of the flexible tube 7 is connected to the bottom of the rain collector 4, and the other end is connected to the diversion tube 8, the diversion tube 8 is arranged on the side of the lamp pole 1 or penetrated inside the lamp pole 1, and the end of the diversion tube 8 facing away from the flexible tube 7 is arranged toward the runner 31 of the hydro-turbine generator 3, and the flexible tube 7 and the inside of the diversion tube 8 form the diversion channel. In this embodiment, when the diversion tube 8 is arranged on the side of the lamp pole 1, the runner 31 of the hydro-turbine generator 3 is located on the side of the lamp pole 1, when the diversion tube 8 is penetrated inside the lamp pole 1 and its end is also located inside the lamp pole 1, the runner 31 of the hydro-turbine generator 3 should also be located inside the lamp pole 1, and if the end of the diversion tube 8 is penetrated along the side of the lamp pole 1 to the outside of the lamp pole 1, the runner 31 of the hydro-turbine generator 3 is also located on the side of the lamp pole 1.

[0032] In one embodiment of the diversion channel, a flexible tube 7 is further included. The interior of the lamp pole 1 is hollow. One end of the flexible tube 7 is connected to the bottom of the rain collector 4, and the other end is connected to the interior of the lamp pole 1. The runner 31 of the hydro-generator 3 is located at the lower end of the interior of the lamp pole 1. The flexible tube 7 and the interior of the lamp pole 1 form the diversion channel. In this embodiment, the interior of the lamp pole 1 is directly used as a part of the diversion channel, and the diversion tube 8 can be omitted.

[0033] In the two embodiments of the above-mentioned flow guide channel, the flexible tube 7 is provided, which will not affect the rotation of the rain collector 4, and can maintain the connection with the flow guide tube 8 when the rain collector 4 rotates. The flexible tube 7 is specifically a pipe that is bendable and has a certain degree of expansion and contraction, such as a corrugated hose or others.

[0034] In the configuration in which the rotation of the above-mentioned hydro-generator 3 is located on the side of the lamp pole 1, rainwater flowing through the runner 31 can directly fall to the ground and flow into the sewer. Based on the configuration in which the runner 31 of the above-mentioned hydro-generator 3 is located inside the lamp pole 1, that is, when rainwater flows along the inside of the lamp pole 1, a water outlet is provided at the bottom of the lamp pole 1 to discharge the rainwater flowing through the runner 31 to the external sewer. When the utility model is applied to a sponge city, a pipe can be provided at the lower end of the lamp pole 1 or on the ground to receive and collect rainwater after passing through the runner 31. The rainwater is merged into the runoff through the pipe, and then filtered and stored. Through the construction of a sponge city, the stored rainwater can be freely migrated in the city, effectively alleviating the urban heat island effect.

[0035] A float water level switch 42 is provided at the connection between the bottom of the rain collector 4 and the diversion channel. The principle of the float water level switch 42 is the existing technology and will not be repeated here. The float water level switch 42 is used to control the rainwater level in the rain collector 4. When the water level in the rain collector 4 is low, the float water level switch 42 remains closed, and rainwater continues to be collected in the rain collector 4. When the water level in the rain collector 4 reaches the corresponding position, the float water level switch 42 automatically opens, and the rainwater flows along the diversion channel to the impeller 31 of the hydro-generator 3, ensuring that a certain amount of rainwater can impact the impeller 31 at a time.

[0036] In one embodiment of the present invention, rainwater energy is converted into electrical energy only through the hydro-generator 3 .

[0037] In another embodiment of the utility model, a piezoelectric power generation unit is also included, which generates electricity by using the impact force of rainwater falling through the piezoelectric effect. It is possible to make more full use of rainwater energy and further improve power generation efficiency. Specifically, the piezoelectric power generation unit includes a piezoelectric material, which can be a single crystal material, a polycrystalline ferroelectric ceramic or other, and the piezoelectric material is electrically connected to a storage battery. The rain collector 4 is funnel-shaped, and the piezoelectric material is arranged on the inner side wall and / or the inner bottom surface of the rain collector 4. When rainwater falls into the rain collector 4, it hits the piezoelectric material on the inner side wall and / or the inner bottom surface of the rain collector 4, so that the piezoelectric material outputs an electric charge. The piezoelectric power generation principle is specifically the prior art. Since the rainwater falling is unstable, the amount of charge converted by the piezoelectric material is also unstable. A capacitor energy storage and a voltage stabilizing module in the prior art can be set, and the current formed by the DC voltage stabilization is then derived to the storage battery through capacitor storage.

[0038] A person skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of protection of the present application is limited to these examples. In line with the concept of the present application, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of different aspects of one or more embodiments of the present application as described above, which are not provided in detail for the sake of simplicity.

[0039] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
