Description

Technical Field

[0001] This solution belongs to the field of LED lighting technology, specifically involving an energy-saving lighting device and its installation method. Background Technology

[0002] Referring to the existing public (announcement) number CN107763545A, the principle of solar streetlights is that sunlight is the energy source. During the day, the solar panel absorbs the sun and converts it into electrical energy to charge the battery. At night, the electrical energy in the battery powers the light source. This streetlight eliminates the need for complex and expensive pipeline laying, allows for arbitrary design and adjustment of the lamp layout, is safe, energy-saving and pollution-free, requires no manual operation, is stable and reliable, saves electricity costs and requires no maintenance.

[0003] See the existing publication (announcement) number CN118687134A, which discloses a street light lighting component and an LED street light, including a light pole with a base welded to the bottom of the light pole, and the street light lighting component. A mounting sleeve is fixedly installed on the top of the light pole, and the mounting sleeve is welded to the cross arm.

[0004] The lamp posts of the aforementioned streetlights are fixed in place. During road construction, large machinery and vehicles are used. These vehicles will be close to the streetlights during operation, and the lamp heads may obstruct the line of sight and operating space of the construction machinery and vehicles, affecting the construction workers' observation of the surrounding environment. Summary of the Invention

[0005] The purpose of this solution is to provide an energy-saving lighting device to solve the problem that existing LED street light poles cannot rotate.

[0006] To achieve the above objectives, this solution provides an energy-saving lighting device, including a lamp post and a photovoltaic panel and LED lights mounted on the lamp post. The lamp post includes a fixed rod and a movable rod, the movable rod being threadedly connected to the fixed rod. The fixed rod is rotatably connected to a sleeve, the sleeve being threadedly connected to the movable rod, and a locking bolt for locking the movable rod is threaded onto the sleeve.

[0007] The principle of this solution is as follows: by loosening the locking bolts and then rotating the sleeve, the movable rod is raised or lowered, thereby raising or lowering the LED light and rotating it to the other side of the road, avoiding obstruction of the view and operating space of construction machinery and vehicles. After construction is completed, the sleeve is rotated in the opposite direction to raise the LED light to its initial position, and the movable rod is locked with the locking bolts.

[0008] The advantages of this solution are: the LED lights can be rotated to the other side of the road, avoiding obstruction of the view and operating space for construction machinery and vehicles. Simultaneously, since the movable pole is threadedly connected to the fixed pole, it can be retracted into the fixed pole, facilitating the transportation and installation of the light pole.

[0009] Furthermore, the movable rod is provided with a bracket, and the bracket is rotatably equipped with fan blades.

[0010] The principle and effect of this solution are as follows: (1) Existing solar panels need to be tilted to receive solar energy, which results in an angle between the solar panel and the lamp post. Due to the existence of this angle, when the wind speed is high, the wind force acts on this angle, and the wind force at the angle will generate an upward lift force on the solar panel. If the lift force exceeds the weight of the solar panel and the resistance of the fixed structure, the solar panel will be lifted by the wind. In this solution, when the wind blows over the fan blades, the rotation of the fan blades not only converts the wind force into rotational power, but also changes the direction of the wind flow, generating a downward pressure on the ground, thereby reducing the lift force generated by the wind on the photovoltaic panel. At the same time, the rotation of the fan blades can disperse the wind force, thereby reducing the wind force acting on the angle, thus preventing the photovoltaic panel from being lifted by the wind. (2) By setting up fan blades, when the wind blows over the fan blades, the rotation of the fan blades not only changes the direction of the wind flow and generates downward pressure, thereby reducing the lift of the wind on the photovoltaic panel, but also reduces the impact of the wind on the angle of the photovoltaic panel by dispersing the wind force, thereby reducing the risk of the photovoltaic panel being lifted by the wind and enhancing the stability of the photovoltaic panel.

[0011] Furthermore, it also includes a lifting assembly, which includes a cylinder and an air pump. The air inlet of the cylinder is connected to the air outlet of the air pump through a pipe. The piston rod of the cylinder is hinged to the carrier plate of the photovoltaic panel. The carrier plate is hinged to the movable rod. A return spring is provided through the piston rod. The two ends of the return spring are fixedly connected to the cylinder body and the piston, respectively. The lifting assembly also includes a drive unit, which is used to intermittently impact the air pump.

[0012] The principle and effect of this solution are as follows: The aforementioned solutions only reduce the wind force acting on the angle of the photovoltaic panel, but the angle still exists, and the photovoltaic panel is still easily lifted. In this solution, the drive unit intermittently impacts the air pump. The gas generated by the air pump is injected into the cylinder through a pipe, thereby stretching the return spring and causing the cylinder piston rod to retract. The piston rod drives the photovoltaic panel carrier to rotate, changing the original obtuse angle between the photovoltaic panel and the lamp post to a right angle, thus rotating the photovoltaic panel to a horizontal position. In the horizontal state, the surface area of ​​the photovoltaic panel is parallel to the wind direction. Compared to when it is placed at an angle, the wind resistance area is reduced, further reducing the direct impact and lift of the wind on the photovoltaic panel. At the same time, the horizontally placed photovoltaic panel also helps to disperse wind force, avoiding concentrated pressure on the surface of the photovoltaic panel, thereby reducing vibration and swaying caused by wind and enhancing the structural stability of the photovoltaic panel.

[0013] Furthermore, the driving unit is a cam.

[0014] The principle and effect of this solution are as follows: This is existing technology and will not be elaborated further.

[0015] Furthermore, the drive unit includes a turntable and a slider. The turntable is coaxially and fixedly connected to the fan blade. The slider is slidably disposed inside the turntable. The slider is connected to a spring. The free end of the spring is fixedly connected to the turntable. The slider is configured in conjunction with an air pump.

[0016] The principle and effect of this solution are as follows: When the fan blades are blown by the wind, they drive the turntable to rotate synchronously. The slider inside the turntable is subjected to the centrifugal force generated by the rotation of the turntable, thus moving away from the center of rotation. The slider is thrown out and intermittently impacts the air pump, causing the air pump to generate gas. When the fan blade speed is slower, the slider is subjected to a smaller centrifugal force and, driven by the spring, retracts back into the turntable and does not contact the air pump.

[0017] Furthermore, the turntable has a sliding groove, and the slider is slidably connected to the sliding groove.

[0018] The principle and effect of this solution is that the slide provides positioning and guidance for the movement of the slider.

[0019] Furthermore, it also includes a cleaning component, which includes a nozzle and a valve. The nozzle is mounted on the photovoltaic panel and is connected to the air outlet of a cylinder via a pipe. The valve is located on the pipe.

[0020] The principle and effect of this solution are as follows: After the wind stops, the photovoltaic panels need to be reset to their initial position. Simultaneously, after the wind picks up, the static electricity on the photovoltaic panels makes it easy for dust blown up by the wind to adhere to them, thus reducing the photovoltaic conversion efficiency. Therefore, dust removal from the photovoltaic panels is also necessary after the wind stops. By opening the valve, the gas inside the cylinder is discharged to the outside of the cylinder, and the piston rod extends and resets under the action of the return spring, thereby resetting the photovoltaic panels to their initial position. At the same time, the depressurized gas inside the cylinder is sprayed onto the photovoltaic panels through the nozzle, thus blowing away the dust adhering to the photovoltaic panels.

[0021] Furthermore, the valve is a manual valve, located inside the turntable, with a through groove in the valve handle, and a bolt slidably installed in the through groove, the bolt being threadedly connected to the slider.

[0022] The principle and effect of this solution are as follows: When the fan speed is high, the slider is thrown out, which drives the bolt to move and rotate the valve handle, thus closing the valve. When the fan speed is low, the airflow is weak, and it is not necessary to keep the photovoltaic panel horizontal. At this time, the slider returns to its original position, driving the bolt to return to its original position and rotating the valve handle, thus opening the valve. This causes the cylinder piston rod to extend and push the photovoltaic panel back to its original position, while also removing dust from the photovoltaic panel.

[0023] Furthermore, a pressure relief valve is provided on the pipe connected to the air inlet; a one-way valve is provided on the pipe connected to the air inlet, and a one-way valve is provided on the pipe connecting the valve and the nozzle.

[0024] The principle and effect of this solution are as follows: When the fan blades rotate, the air pump continuously generates gas to fill the cylinder. Therefore, a pressure relief valve is installed to release excess gas when the pressure inside the cylinder reaches a threshold, preventing the cylinder pressure from exceeding the threshold. A one-way valve is installed to ensure that the gas in the pipeline flows in a preset direction.

[0025] An installation method for an energy-saving lighting device includes applying the energy-saving lighting device as described above, comprising the following steps:

[0026] Step S10: Construction preparation. Based on the street light construction drawings, determine the installation position of the light poles and the center stake and edge line of the street light foundation pit and trench.

[0027] Step S20: Excavation of the foundation pit. According to the determined center stake and trench edge line, excavate the foundation pit for the street lamp, and check the size and shape of the foundation pit to ensure that the foundation pit is flat and free of debris.

[0028] Step S30: Light pole installation. Place the fixing pole into the foundation pit, ensure that the fixing pole is vertical, and use concrete or cement mortar to fix the fixing pole in the foundation pit.

[0029] Step S40: Install the bracket. Secure the bracket to the movable rod with bolts, then rotate the fan blades to install them in the corresponding holes of the bracket, and install the LED lights at the free end of the bracket.

[0030] Step S50: Install the photovoltaic panel by hingedly connecting the middle of the carrier plate to the top of the movable rod, then installing the photovoltaic panel inside the carrier plate, and then installing the nozzle at the top of the photovoltaic panel;

[0031] Step S60: Install the lifting assembly, place the cylinder into the fan blade and fix the cylinder body, and then hinge the piston rod of the cylinder to the top of the carrier plate.

[0032] Step S70: Install the drive unit, install the air pump and turntable, and ensure that the slider can contact the air pump when the turntable rotates. Then connect the corresponding pipes and valves in sequence.

[0033] Step S80: Debugging and inspection. Raise the LED light to the predetermined height by rotating the sleeve and make the LED light face the road surface. Then check the power generation efficiency of the photovoltaic panel, the lighting effect of the LED light, the operation of the lifting component and the working status of the cleaning component. Finally, record all data during the installation and acceptance process and archive them for future reference. Attached Figure Description

Detailed Implementation

[0039] The following will describe the concept and technical effects of the present invention clearly and completely with reference to embodiments, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0040] Example:

[0041] Please see Figure 1 An energy-saving lighting device includes a lamp post 1 and a photovoltaic panel 2 and an LED lamp 3 mounted on the lamp post 1. The lamp post 1 includes a fixed rod 11 and a movable rod 12. The outer wall of the movable rod 12 is provided with external threads, and the inner wall of the fixed rod 11 is provided with internal threads, so that the movable rod 12 can be threaded into the fixed rod 11. The top of the fixed rod 11 is rotatably connected to a sleeve 13. The inner wall of the sleeve 13 is provided with internal threads, and the sleeve 13 is threadedly connected to the movable rod 12. A locking bolt for locking the movable rod 12 is threadedly connected to the sleeve 13. By tightening the locking bolt, the locking bolt is pressed against the movable rod 12.

[0042] Specific working principle: By loosening the locking bolts and then rotating the sleeve 13, the movable rod 12 is raised or lowered, thereby raising or lowering the LED light 3 and rotating it to the other side of the road surface, avoiding obstruction of the view and operating space of construction machinery and vehicles. After construction is completed, the sleeve 13 is rotated in the opposite direction to raise the LED light 3 to its initial position, and the movable rod 12 is locked with the locking bolts.

[0043] Please see Figure 1 and Figure 2A bracket 4 is mounted on the movable rod 12, and a fan blade 6 is rotatably mounted on the bracket 4. The fan blade 6 is located at the front end of the angle between the photovoltaic panel 2 and the movable rod 12. When wind blows across the fan blade 6, the rotation of the fan blade 6 not only converts the wind force into rotational power, but also changes the direction of the wind flow, generating a downward pressure on the ground, thereby reducing the lift force exerted by the wind on the photovoltaic panel 2. At the same time, the rotation of the fan blade 6 can disperse the wind force, thereby reducing the wind force acting at the angle and preventing the photovoltaic panel 2 from being lifted by the wind.

[0044] Please see Figure 2 and Figure 3 The system also includes a lifting assembly 5, which comprises a cylinder 51 and an air pump 52. The air inlet 511 of the cylinder 51 is connected to the air outlet of the air pump 52 via a pipe. A pressure relief valve and a one-way valve are provided on the pipe connected to the air inlet 511. The piston rod 512 of the cylinder is hinged to the top of the carrier plate 21 of the photovoltaic panel 2, and the middle part of the carrier plate 21 is hinged to the movable rod 12. A return spring 513 passes through the piston rod 512, and the two ends of the return spring 513 are fixedly connected to the cylinder body and the piston, respectively. The lifting assembly 5 also includes a drive unit 53, which is used to intermittently impact the air pump 52. The drive unit 53 can be a cam or a cylinder, etc. The system also includes a cleaning assembly 7, which comprises a nozzle 71 and a valve 72. The nozzle 71 is located at the top of the photovoltaic panel 2 and is connected to the air outlet 514 of the cylinder 51 via a pipe. The valve 72 is located on the pipe, and a one-way valve is provided on the pipe connecting the valve 72 and the nozzle 71.

[0045] Specific working principle: The drive unit 53 intermittently impacts the air pump. The gas generated by the air pump 52 is injected into the cylinder 51 through the pipe, thereby stretching the return spring 513 and causing the piston rod 512 of the cylinder 51 to retract. The piston rod 512 drives the carrier plate 21 to rotate, changing the obtuse angle between the photovoltaic panel 2 and the lamp post 1 to a right angle, thus rotating the photovoltaic panel 2 to a horizontal position. In the horizontal state, the surface area of ​​the photovoltaic panel 2 is parallel to the wind direction. Compared with the inclined placement, the wind resistance area is reduced, further reducing the direct impact and lift of the wind on the photovoltaic panel 2. At the same time, the horizontally placed photovoltaic panel 2 also helps to disperse the wind force, avoiding the concentrated pressure generated by the wind on the surface of the photovoltaic panel 2, thereby reducing the vibration and sway caused by the wind and enhancing the structural stability of the photovoltaic panel 2. Furthermore, after the wind stops, the photovoltaic panel 2 needs to be returned to its initial position. At the same time, after the wind picks up, due to the static electricity on the photovoltaic panel 2, the dust stirred up by the wind is easily adhered to the photovoltaic panel 2, thereby reducing the photoelectric conversion efficiency of the photovoltaic panel 2. Therefore, dust removal of the photovoltaic panel 2 is also necessary after the wind stops. By opening valve 72, the gas in cylinder 51 is discharged to the outside of the cylinder, and piston rod 512 is pushed back and extended by the return spring 513, thereby resetting the photovoltaic panel 2 to its initial position. At the same time, the depressurized gas in cylinder 51 is sprayed onto the photovoltaic panel 2 through the nozzle, thereby blowing away the dust adhering to the photovoltaic panel 2.

[0046] Please see Figure 4 The drive unit 53 includes a turntable 531 and a slider 532. The turntable 531 is coaxially and fixedly connected to the fan blade 6. The turntable 531 has a groove (not shown in the figure) slidably connected to the slider 532. The slider 532 is connected to a spring 533, and the free end of the spring 533 is fixedly connected to the turntable 531. The slider 532 is configured to cooperate with the air pump 52. The valve 72 is a manual valve, located inside the turntable 531. The handle 721 of the valve 72 has a through groove 7211, and a bolt is slidably installed in the through groove 7211. The bolt is threadedly connected to the slider 532.

[0047] Specific working principle: When the fan blade 6 is blown by the wind, it drives the turntable 531 to rotate synchronously. The slider 532 inside the turntable 531 is subjected to the centrifugal force generated by the rotation of the turntable 531, thus moving away from the center of rotation. The slider 532 is thrown out and intermittently impacts the air pump 52, causing the air pump 52 to generate gas. At the same time, the slider 532 drives the bolt to move, causing the valve handle 721 to rotate and the valve 72 to be in the closed state. When the fan blade 6 rotates at a slower speed, the surface wind force is small, and it is not necessary to keep the photovoltaic panel 2 in a horizontal state. The slider 532 is subjected to a small centrifugal force and retracts into the turntable 531 under the action of the spring 533, no longer contacting the air pump 52. At the same time, the slider 532 resets, causing the bolt to reset, causing the valve handle 721 to rotate, thus opening the valve 72. This causes the cylinder piston rod 512 to extend and push the photovoltaic panel 2 to reset, and remove dust from the photovoltaic panel 2.

[0048] To better achieve the above-mentioned lighting equipment, the present invention also provides an energy-saving lighting equipment installation method, including the application of such an energy-saving lighting equipment, comprising the following steps:

[0051] Step S30: Light pole installation. Place the fixing pole 11 into the foundation pit, ensure that the fixing pole 11 is vertical, and use concrete or cement mortar to fix the fixing pole 11 in the foundation pit.

[0052] Step S40: Install the bracket. Secure the bracket 4 to the movable rod 12 with bolts. Then rotate the fan blade 6 and install it in the corresponding hole of the bracket 4. Install the LED light 3 at the free end of the bracket 4.
