Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent lighting devices, and particularly relates to an integrated solar intelligent guiding street lamp. Background Art

[0002] A street lamp is a lighting device that provides lighting for roads, generally referring to the lamps within the range of road surface lighting in traffic lighting. Street lamps are widely used in various places that require lighting. Solar street lamps apply new energy technologies, which can convert solar energy into electrical energy and be used for lighting. They have gradually replaced traditional public power lighting street lamps, reducing power consumption and making positive contributions to the energy conservation and environmental protection of cities.

[0003] With the rise and popularization of the concept of smart cities, more requirements are put forward for the functions of public facilities in cities. As an important part of urban public facilities, street lamps are a very important link in the development and construction of smart cities. Therefore, some intelligent guiding street lamps have emerged. For example, the intelligent integrated solar street lamp disclosed in CN117685523A projects road information on the ground through an AR module and uses a human body sensing module to achieve reasonable switching between the main lamp and the servo lamp to reduce energy consumption. However, there are still some problems:

[0004] 1. During the day, under long-term direct sunlight, the solar panel is prone to a gradual increase in temperature, which affects the light energy conversion efficiency and service life of the solar panel.

[0005] 2. At night, the storage battery needs to supply power to the lamp group. However, in special areas with relatively low temperatures at night, the low temperature at night will cause an increase in the internal resistance of the storage battery and a decrease in the discharge efficiency, resulting in a sharp reduction in the power supply time. Summary of the Invention

[0006] In order to solve the above technical problems, the inventor obtained the technical solution of the present invention through practice and summary. The heat of the solar panel during the day is collected by using a phase change energy storage partition and used to keep the storage battery warm at night to ensure the discharge efficiency and the effective power supply time.

[0028] The AR projection module is used to project AR road information on the ground.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention uses the energy storage phase change partition board to collect the heat of the solar panel during the day and use it to keep the storage battery warm and protected at night, ensuring the discharge efficiency of the storage battery, and thus ensuring the effective power supply time. In this way, it can solve the problem of low light energy conversion efficiency caused by the high temperature of the solar panel during the day when the temperature difference between day and night is large, and the problem of low discharge efficiency caused by the increase of the internal resistance of the storage battery due to the low temperature at night.

[0031] 2. When the energy storage phase change partition of the present invention absorbs heat from the solar panel during the day (when the temperature is too high during the day), the temperature will be too high, resulting in exceeding the set capacity of the energy storage phase change partition. In this way, the heat of the solar panel will surge, and then the problem of low light energy conversion efficiency will also occur. The inventor adds a temperature sensor to the energy storage phase change board. When the temperature exceeds the set range, the control component will control the cooling fan to automatically start to actively cool the energy storage phase change board, and dynamically balance to maintain the solar panel in a temperature range with high photoelectric conversion efficiency, thereby ensuring the light energy conversion efficiency and power generation of the solar panel during the day.

[0032] 3. In order to ensure the effective storage of heat by the energy storage phase change plate and timely dissipation of heat when the set capacity is exceeded, the memory alloy will drive the blocking plate to move outward when the set capacity is exceeded, open cooling channel 1 and cooling channel 2, and utilize the structural depth of cooling channel 1 and cooling channel 2 to cooperate with the cooling bin and air-cooling blades to achieve efficient cooling effect, so that the airflow of the cooling fan can take away the excess heat in the energy storage phase change plate in time through the set route and maintain it within the set range, thereby dynamically maintaining the temperature of the solar panel.

[0033] 4. The present invention is provided with an air inlet and an air outlet on the bottom surface of the lamp housing. Due to the problem of local internal high temperature caused by the internal components of the lamp housing (heat generated by battery charging, component operation, etc.), the internal temperature of the lamp housing is monitored by temperature sensor 2. Once the set temperature range is exceeded, the cooling fan can also be started, and the air inlet and the air outlet are automatically opened to form a directional airflow to dynamically maintain the internal temperature.

[0034] 5. The present invention adopts the design of elastic opening and closing strip 1 and elastic opening and closing strip 2, and solves the inherent defects of "continuous exposure and passive defense" of traditional normally open ventilation ports through intelligent opening and closing + dynamic sealing, and achieves comprehensive improvement in dustproof, waterproof, energy saving and life. It is especially suitable for solar street lights in complex outdoor environments, and is an innovative solution that takes into account functionality and reliability.

[0035] 6. The elastic opening and closing strip and filter structure adopted in the present invention, the elastic opening and closing strip is connected with the vibration rod and the force storage member to realize the cleaning of the filter structure, and the vibration cleaning and filtering of the filter structure can be realized once during each opening and closing, thereby avoiding the problem of premature clogging of the filter structure.

Detailed implementation manners

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0050] Embodiment 1

[0051] As Figures 1 to 3 、 Figure 9 shown, the integrated solar intelligent guide street lamp includes:

[0052] Lamp housing 100, the top of the lamp housing 100 is provided with an opening, and the bottom is provided with an outward convex body extending downward;

[0053] Solar panel 200, the solar panel 200 is hermetically installed at the opening;

[0054] Storage battery 300 and control component 400, the storage battery 300 and the control component 400 are installed in the outward convex body;

[0055] Light-emitting component 500, the light-emitting component 500 is installed on the bottom surface of the lamp housing 100;

[0056] Energy storage phase change partition 600, the energy storage phase change partition 600 is installed in the lamp housing 100.

[0057] Among them, the energy storage phase change partition 600 sequentially includes a heat absorption plate 601, a heat insulation plate 602, an energy storage phase change plate 603, a heat preservation plate 604, and a heat release plate 605 from top to bottom.

[0058] The heat absorption plate 601 is attached to the bottom surface of the solar panel 200. During installation, thermal conductive silicone grease can be applied on the heat absorption plate 601 to ensure effective heat dissipation contact with the solar panel 200. A number of heat conduction sleeves 606 are evenly installed on the bottom surface of the heat absorption plate 601. A thermal expansion and contraction column 608 and a heat conduction column 607 are installed in each heat conduction sleeve 606. The thermal expansion and contraction column 608 absorbs heat and elongates to drive the heat conduction column 607 to move outward, or contracts when cooled to drive the heat conduction column 607 to retract. The heat conduction column 607 and the heat conduction sleeve 606 are in sliding fit and part of it can extend to the outside of the heat conduction sleeve 606.

[0059] The heat insulation plate 602 is clamped inside the lamp housing 100. A first guiding hole 609 is provided on the heat insulation plate 602. The first guiding hole 609 and the heat conduction column 607 are in sliding fit.

[0060] A number of sleeves 612 are evenly interspersed and distributed on the energy storage phase change plate 603. The outer shell of the energy storage phase change plate 603 is made of a heat conductive material and the inside is filled with an energy storage phase change material, such as a phase change material like paraffin.

[0061] A second guiding hole 613 is evenly provided on the heat preservation plate 604. The second guiding hole 613, the first guiding hole 609, and the sleeve 612 are in corresponding positions.

[0062] A number of heat release sleeves 614 are evenly installed on the top surface of the heat release plate 605. A heat release column 615 is in sliding fit in each heat release sleeve 614. Part of the heat release column 615 can extend to the outside of the heat release sleeve 614 and is in sliding fit with the second guiding hole 613. The heat release column 615 and the heat conduction column 607 are connected by a linkage rod 616. The linkage rod 616 is of a U-shaped structure and is made of a heat insulation material. The linkage rod 616 is in sliding fit in the sleeve 612. The heat release plate 605 is connected to a heat preservation cover 620 through a number of heat conduction wires. The heat preservation cover 620 covers the outside of the storage battery 300.

[0063] During the day, the solar panel 200 converts photoelectricity to supply power to the storage battery 300. Since the temperature of the solar panel 200 covered for a long time will rise, the heat absorption plate 601 will absorb the heat of the solar panel 200. At the same time, the thermal expansion and contraction column 608 absorbs heat and elongates, driving the heat conduction column 607 to extend outwards and attach to the surface of the energy storage phase change plate 603. At the same time, the heat conduction column 607 is driven by the linkage rod 616 to separate the heat release column 615 from the energy storage phase change plate 603, so that the energy storage phase change plate 603 is in a continuous heat absorption state. At night, due to the temperature drop, the thermal expansion and contraction column 608 contracts when it encounters cold, driving the heat conduction column 607 to retract into the heat conduction sleeve 606. The heat conduction column 607 disengages from the energy storage phase change plate 603 and drives the heat release column 615 to contact the energy storage phase change plate 603 through the linkage rod 616, and transfers the heat conduction wire to the heat preservation cover 620 through the heat release plate 605 to perform heat preservation treatment on the storage battery 300. It solves the problem that the heat generated during the light energy conversion of the solar panel 200 during the day affects the light energy conversion efficiency, and uses its heat to perform heat preservation treatment on the storage battery 300 at night, thereby effectively extending the discharge time limit.

[0064] Embodiment 2

[0065] In the scheme of the street lamp, due to the high natural weather temperature during the day and the new heat generated during the light energy conversion process, it is easy to cause the energy storage phase change plate 603 to be overloaded, which in turn causes the solar panel 200 to be unable to maintain the temperature range in the high-efficiency light energy conversion efficiency interval. Therefore, the inventor made the following improvements:

[0066] As Figure 2 、 Figure 3 shown, a cooling fan 101 is installed in the lamp housing 100, and the electric energy of the cooling fan 101 is provided by the storage battery 300;

[0067] As Figure 5 、 Figure 8 shown, a temperature sensor 102, a first cooling air duct 103, a cooling chamber 107 and a second cooling air duct 104 are arranged on the top surface of the heat preservation plate 604. The first cooling air duct 103 and the second cooling air duct 104 are respectively located on both sides of the cooling chamber 107. The cooling chamber 107 is of a circular structure and an air-cooled blade 108 is installed in the middle.

[0068] The temperature of the energy storage phase change plate 603 is monitored in real time by the temperature sensor 102. When it exceeds the threshold value, the control component 400 will control the cooling fan 101 to automatically start, forming an air flow in the lamp housing 100. The air flow drives the air-cooled blade 108 in the cooling chamber 107 to rotate through the first cooling air duct 103 and the second cooling air duct 104, thereby dissipating the excess heat in time, being able to maintain the energy storage phase change plate 603 within a certain temperature range interval, effectively maintaining the solar panel 200 within the high-efficiency light energy conversion efficiency range, and ensuring the power generation.

[0069] Embodiment 3

[0070] On the basis of Embodiment 2, heat preservation treatment is required when the energy storage phase change plate 603 absorbs heat, and when the temperature exceeds the set threshold temperature, heat dissipation treatment is also required in a timely manner to ensure that the heat that can be absorbed in the energy storage phase change plate 603 is maintained within the set range. The inventor makes the following improvements:

[0071] As Figure 2 、 Figure 4 shown, blocking plates 106 are provided at one ends of the first cooling air duct 103 and the second cooling air duct 104 away from the cooling bin 107. Two groups of guide posts 105 are provided on the side of the blocking plate 106 opposite to the energy storage phase change plate 603. The two groups of guide posts 105 are respectively slidably engaged with the heat insulation plate 602 and the heat preservation plate 604. The side part of the energy storage phase change plate 603 and the blocking plate 106 are connected by a shape memory alloy 109.

[0072] When the temperature of the energy storage phase change plate 603 exceeds the set threshold, the shape memory alloy 109 elongates in length and pushes the blocking plate 106 outwards, thereby opening the air flow channels of the first cooling air duct 103 and the second cooling air duct 104, forming an air flow for dissipating heat from the energy storage phase change plate 603. When the temperature drops below the threshold, the shape memory alloy 109 contracts in length and will move the blocking plate 106 inwards in a timely manner and re-block the blocking plate 106 at the inlets and outlets of the first cooling air duct 103 and the second cooling air duct 104, thereby maintaining the heat preservation of the energy storage phase change plate 603.

[0073] Embodiment 4

[0074] On the basis of Embodiment 3, as Figure 5 、 Figure 8 shown, a diversion groove 110 is provided on the bottom surface of the heat preservation plate 604 near one side of the first cooling air duct 103. The diversion groove 110 has a structure with a large bottom and a small top and is gradually arranged closer to the side of the blocking plate 106 from bottom to top. The air flow generated by the cooling fan 101 will be introduced from the first cooling air duct 103 through the diversion groove 110, and the air flow will be directed through the cooling bin 107 and the second cooling air duct 104, effectively maintaining the temperature of the energy storage phase change plate 603.

[0075] As Figure 8 shown, the first cooling air duct 103 and the second cooling air duct 104 are arranged as follows. Firstly, the flow direction of the heat dissipation air flow can be set and effective heat dissipation can be achieved. The air inlet size of the first cooling air duct 103 is larger than the outlet size and the inlet depth is greater than the outlet depth. The air inlet size of the second cooling air duct 104 is smaller than the outlet size and the inlet depth is less than the outlet depth.

[0076] Embodiment 5

[0077] In the solution of the street lamp, during the day, in addition to the above-mentioned effects of heat and temperature, there is also the heat generated during the charging of the storage battery 300, which will also cause the internal temperature to rise. Since this temperature will also bring certain negative effects, such as the aging of internal components and potential safety hazards, etc., the inventor makes the following improvements:

[0078] As Figure 5 、 Figure 6 、 Figure 7 As shown, a second temperature sensor 111 is installed inside the lamp housing 100;

[0079] One side of the bottom of the lamp housing 100 is the air inlet, and the other side is the air outlet. A filter structure 112 and a first elastic opening and closing strip 113 are installed at the air inlet, and a second elastic opening and closing strip 114 is installed at the air outlet;

[0080] The free ends of the first elastic opening and closing strip 113 and the second elastic opening and closing strip 114 are abutted and sealed on the lamp housing 100. The free ends of the first elastic opening and closing strip 113 and the second elastic opening and closing strip 114 gradually deviate from the fixed end along the air inlet and outlet direction and the thickness gradually decreases, which is conducive to realizing automatic opening and closing.

[0081] The second temperature sensor 111 is used to monitor the temperature inside the lamp housing 100 in real time. When the temperature exceeds the threshold, the control component 400 will control the cooling fan 101 to automatically turn on, forming an air flow inside the lamp housing 100. The blocking plate 106 realizes automatic opening and closing according to the temperature of the energy storage phase change plate 603 through the shape memory alloy 109, creating a negative pressure at the first elastic opening and closing strip 113 and a positive pressure at the second elastic opening and closing strip 114. The air inlet and outlet are automatically opened, forming a directional air flow. The formation of the air flow will timely dissipate the internal heat, ensuring that the temperature inside the lamp housing 100 is always below the set range. The filter structure 112 can remove dust, etc. The air inlet and outlet are dynamically opened and closed, which can isolate the external environment, avoid long-term contact with the outside, and at the same time have many advantages such as heat preservation and dust prevention when needed.

[0082] Embodiment 6

[0083] On the basis of Embodiment 5, since the street lamp is long-term outdoors, it is easy to cause the problem of blockage of the filter structure 112, and the traditional filtering method uses a complex cleaning structure to achieve regular cleaning. The inventor makes the following improvements:

[0084] As Figure 7 As shown, a connecting wire 115 is arranged on the first elastic opening and closing strip 113. A power storage member 117 and a rotatable vibration rod 116 are installed on the filter structure 112. One end of the vibration rod 116 is connected to the connecting wire 115 and the other end is connected to the power storage member 117. The filter structure 112 is installed on the lamp housing 100 with elastic structures on both sides, and the up-and-down shaking effect can be achieved through the elastic structures on the upper and lower sides.

[0085] The length of the rotation node of the excitation rod 116 from the connecting wire 115 is about 3 to 5 times the length of the rotation node of the excitation rod 116 from the energy storage member 117. Using the lever principle and cooperating with the energy storage member 117 (spring), one opening and closing can complete one excitation and cleaning.

[0086] Embodiment 7

[0087] In the scheme of the street lamp, since the storage battery 300 generates a certain amount of heat during the charging state during the day and sometimes needs to dissipate heat, the storage battery 300 needs to be cooled in time at this time. The inventor makes the following improvements:

[0088] As Figure 2 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 As shown, the heat preservation cover 620 includes a plurality of unit covers 621. The side of the unit cover 621 is provided with a connecting pin 622 and a vertical sliding groove 623. A sliding pin 624 is installed in the vertical sliding groove 623. Adjacent two unit covers 621 are connected by an X-shaped connecting rod 625. Four hinge points of the X-shaped connecting rod 625 are respectively connected to the corresponding sliding pin 624 or connecting pin 622; the unit cover 621 realizes linkage through the X-shaped connecting rod 625, sliding pin 624, and connecting pin 622, and further realizes the gap between two unit covers 621 to realize the overflow of the heat generated during the charging of the storage battery 300.

[0089] A guide bar 626 and a micro motor 627 are installed in the lamp housing 100. One of the unit covers 621 is fixed on the guide bar 626, and the remaining unit covers 621 are slidably fitted on the guide bar 626. A nut 628 is installed on the unit cover 621 that is far from the fixed unit cover 621. The output end of the micro motor 627 is connected with a lead screw 629 that cooperates with the nut 628, and the lead screw 629 is rotatably installed in the lamp housing 100.

[0090] The inner wall surface of the unit cover 621 is provided with a heat conduction structure 630 connected to a heat conduction wire. The heat conduction structure 630 releases the heat in the energy storage phase change plate 603 to keep the internal storage battery 300 warm. A heat preservation cotton is arranged on one side where two unit covers 621 contact, and the heat preservation cotton can ensure the maintenance of the temperature in the low-temperature environment at night.

[0091] During the day, the thermal insulation cover 620 is in an open state for the storage battery 300, and the cooling fan 101 can dissipate heat from the storage battery 300.
