Description

Technical Field

[0001] The present invention relates to the technical field of lighting, and in particular to an energy-saving lighting device for urban roads. Background Art

[0002] Energy-saving lighting equipment can help cities achieve emission reduction targets and reduce long-term operating costs by reducing energy consumption, carbon emissions and maintenance frequency. Energy-saving lighting equipment for urban roads plays an important role in ensuring nighttime traffic safety. Traditional road lighting equipment usually adopts a fixed lamp rack structure. The shell of the lighting equipment is mostly made of glass, acrylic board, and plastic. The shell is exposed to a complex environment for a long time and will be impacted by external forces such as strong winds, dust, and rain. Strong winds and impurities they carry (such as sand and gravel) will wear the surface of the shell and even cause the shell to crack due to impact. Once the shell is broken, the energy-saving lamp in the shell will be in direct contact with the external environment, which will increase the probability of damage to the energy-saving lamp, thereby affecting the lighting effect of the internal energy-saving lamp, and then leading to increased maintenance frequency and cost. Summary of the invention

[0003] In order to overcome the shortcomings pointed out in the above background technology, the present invention provides an energy-saving lighting device for urban roads.

[0004] The technical solution is: an energy-saving lighting device for urban roads, comprising a shell arranged on a lamp holder, an energy-saving lamp is arranged in the shell, and a hollow rotating shaft is rotatably connected to the position of the lamp holder close to the shell; The hollow shaft is provided with a limiting portion, the shell is fixedly connected with a first flexible block, the first flexible block is used to limit the limiting portion, and a second flexible block rotatably connected to the lamp holder is fixedly connected to a side of the shell away from the hollow shaft; The lamp holder is slidably connected with a sliding frame, the shell is used to squeeze the sliding frame, the lamp holder is fixed with a buffer airbag, the sliding frame is located between the shell and the buffer airbag, the sliding frame is used to squeeze the buffer airbag, an elastic member is fixed between the sliding frame and the lamp holder, and the elastic coefficient of the buffer airbag is greater than the elastic coefficient of the elastic member between the sliding frame and the shell.

[0005] Furthermore, the contact point between the housing and the sliding frame is located at an edge thereof.

[0006] Furthermore, an inner liner is fixedly connected to the shell, and a chamber is provided between the inner liner and the shell.

[0007] Furthermore, a power component is installed in the lamp holder, and the power component is used to drive the hollow shaft to rotate.

[0008] Furthermore, a pressure sensor is installed at a position of the lamp holder close to the buffer airbag, the sliding frame is used to press the pressure sensor, and there is a distance between the pressure sensor and the sliding frame.

[0009] Furthermore, the buffer airbag is connected to the chamber via a connecting pipe.

[0010] Furthermore, the first flexible block is an inflatable airbag, the chamber is communicated with the interior of the first flexible block, and there is a gap between the second flexible block and the lamp holder, and the gap is communicated with the connecting pipe.

[0013] Furthermore, the elastic coefficient of the cleaning block is smaller than the elastic coefficient of the buffer airbag.

[0014] Beneficial effects of the present invention: 1. The present invention changes the existing shell from fixed installation to movable installation, so that when the shell is impacted, the movement of the shell is buffered through the deformation of the first flexible block, the second flexible block and the buffer airbag, thereby reducing the probability of the shell surface being broken due to the impact of strong wind and impurities carried by it, thereby increasing the upper limit of the impact that the shell can withstand, and further improving the damage resistance of the shell; 2. By rotating the shell regularly, the clear surface and the unclear surface of the shell are continuously replaced to reduce the impact of the unclear shell surface on the lighting effect of the energy-saving lamp. In the process of shell rotation, the scraper and the cleaning block scrape off dry impurities and wipe off wet impurities on the shell surface respectively to maintain the clarity of the shell. When the shell is moved by strong wind, the first flexible block and the second flexible block are actively expanded, and the first flexible block and the second flexible block clamp the limiting part of the hollow rotating shaft to enhance the stability of the shell, reduce the shaking amplitude of the shell, and ensure the lighting stability of the device. After the shell is damaged, the shell is automatically rotated 180°, and the damaged part of the shell is rotated into the lamp holder to reduce the impact of the shell damage on the lighting effect of the internal energy-saving lamp.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example 1 This embodiment discloses an energy-saving lighting device for urban roads, which is used for lighting urban roads and improves the upper limit of the impact that the housing of the lighting device can withstand through buffering, thereby reducing the probability of damage to the housing.

[0019] like Figure 1-Figure 7As shown, it includes a shell 2 arranged on a lamp stand 1, and the lamp stand 1 is provided with a control terminal and a solar panel which are not shown in the figure. The shell 2 is made of a transparent material, such as an acrylic plate. An energy-saving lamp 201 electrically connected to the control terminal is arranged in the shell 2. The lamp stand 1 is rotatably connected to a hollow shaft 3 near the shell 2, and a circuit line of the energy-saving lamp 201 passes through the hollow shaft 3 to the outside of the shell 2; the hollow shaft 3 is provided with a limiting portion 4, and a first flexible block 5 is fixedly connected to the front side of the shell 2, and the first flexible block 5 is used to limit the limiting portion 4. When the hollow shaft 3 drives the limiting portion 4 to rotate, the limiting portion 4 drives the first flexible block 5 to rotate, and a second flexible block 6 rotatably connected to the lamp stand 1 is fixedly connected to the rear side of the shell 2. The torsion resistance of the first flexible block 5 is higher than its compression resistance, and the torsion resistance of the second flexible block 6 is higher than its compression resistance. When the shell 2 is impacted and moves laterally, the shell 2 squeezes the first flexible block 5 and the second flexible block 6. A flexible block 5 and a second flexible block 6 are compressed and deformed, and the shell 2, the hollow rotating shaft 3, the limiting part 4, the first flexible block 5 and the second flexible block 6 can all be removed from the lamp stand 1; the lamp stand 1 is slidably connected with a sliding frame 7, the shell 2 is used to squeeze the sliding frame 7, the lamp stand 1 is fixed with a buffer airbag 8, the sliding frame 7 is located between the shell 2 and the buffer airbag 8, the sliding frame 7 is used to squeeze the buffer airbag 8, and an elastic member is fixed between the sliding frame 7 and the lamp stand 1, wherein the elastic member between the sliding frame 7 and the lamp stand 1 is a tension spring, and the elastic coefficient of the buffer airbag 8 is greater than the elastic coefficient of the elastic member between the sliding frame 7 and the shell 2. When the buffer airbag 8 initially expands, the elastic member between the sliding frame 7 and the shell 2 supports the sliding frame 7 to keep the buffer airbag 8 in an expanded state, and the contact points between the shell 2 and the sliding frame 7 are located at the edge positions on the front and rear sides thereof, and the thickness of the front and rear edges of the shell 2 is greater than the rest of the positions thereon to reduce the probability of the shell 2 being compressed and damaged.

[0020] Initially: The buffer airbag 8 is in an expanded state, and the elastic member between the sliding frame 7 and the lamp frame 1 is in a stretched and force-storing state.

[0021] During use: When it is necessary to use the device for lighting, the energy-saving lamp 201 is turned on through the control terminal. During the use of the device for lighting, if the external environment is in windy weather, the strong wind will impact the shell 2, and even the strong wind will carry impurities to impact the surface of the shell 2. When the strong wind impacts the right side of the shell 2, the shell 2 moves to the left due to the impact of the strong wind, and the shell 2 squeezes the first flexible block 5 and the second flexible block 6, causing the first flexible block 5 and the second flexible block 6 to deform. At the same time, the shell 2 squeezes the sliding frame 7, and the sliding frame 7 squeezes the buffer airbag 8, which also deforms. The elastic part between the sliding frame 7 and the lamp frame 1 shrinks, and the movement of the shell 2 is buffered by the deformation of the first flexible block 5, the second flexible block 6 and the buffer airbag 8, thereby reducing the probability of the surface of the shell 2 being broken due to the impact of the strong wind and the impurities it carries, thereby increasing the upper limit of the impact that the shell 2 can withstand, and then improving the damage resistance of the shell 2.

[0022] When it is necessary to stop using the device, the energy-saving lamp 201 is turned off through the control terminal. If the energy-saving lamp 201 needs to be replaced, the operator removes the shell 2, the hollow shaft 3, the limit part 4, the first flexible block 5 and the second flexible block 6, and then pulls out the hollow shaft 3, the limit part 4 and the first flexible block 5 forward to replace the energy-saving lamp 201 inside the shell 2, and finally installs and resets the shell 2, the hollow shaft 3, the limit part 4, the first flexible block 5 and the second flexible block 6.

[0023] Example 2 This embodiment discloses an energy-saving lighting device for urban roads. Based on the first embodiment, it also has the function of automatically detecting and replacing the damaged surface of the shell 2.

[0024] like Figure 6 and Figure 7 As shown, an inner liner 9 is fixedly connected to the shell 2, and a chamber 901 is provided between the inner liner 9 and the shell 2. The material of the inner liner 9 is the same as that of the shell 2. Through the double-layer structure of the inner liner 9 and the shell 2 and the chamber 901 therebetween, multi-layer protection is provided for the energy-saving lamp 201 in the shell 2.

[0025] like Figure 3 and Figure 4 As shown, a power component 10 is installed in the lamp holder 1. The power component 10 can be composed of a motor and a gear set. The gear set is composed of two spur gears, one of which is fixedly connected to the output shaft of the motor, and the other is fixedly connected to the hollow shaft 3. The motor of the power component 10 is electrically connected to the control terminal. The power component 10 is used to drive the hollow shaft 3 to rotate. The left half of the shell 2 is located in the lamp holder 1. Since the torsional resistance of the first flexible block 5 is higher than its compressive resistance, the first flexible block 5 does not deform when the limiting portion 4 drives the first flexible block 5 to rotate.

[0026] like Figure 6 and Figure 7 As shown, a pressure sensor 11 is installed at a position of the lamp holder 1 near the buffer airbag 8. The pressure sensor 11 is electrically connected to the control terminal. The sliding frame 7 is used to squeeze the pressure sensor 11. There is a distance between the pressure sensor 11 and the sliding frame 7. After the pressure sensor 11 is compressed, the power part 10 is controlled by the control terminal to drive the hollow shaft 3 to rotate 180°.

[0027] like Figure 7 As shown, the cushion airbag 8 is connected to the chamber 901 through a connecting pipe 12. Initially, the cushion airbag 8 is in an expanded state. When the shell 2 is damaged, the gas in the chamber 901 leaks out, causing the gas in the cushion airbag 8 to leak into the chamber 901 through the connecting pipe 12.

[0028] like Figure 7 As shown, the first flexible block 5 is an expandable airbag, the chamber 901 is connected to the interior of the first flexible block 5, there is a gap between the second flexible block 6 and the lamp holder 1, and the gap is connected to the connecting pipe 12. When the buffer airbag 8 is pressurized, the gas in the buffer airbag 8 enters the interior of the first flexible block 5 and the gap between the second flexible block 6 and the lamp holder 1 at the same time through the connecting pipe 12 and the chamber 901.

[0029] The working process of this embodiment is similar to that of Embodiment 1, and is described in detail as follows: During the use of the present device, when the right side of the shell 2 is contaminated with impurities (such as dust and mud) or scratches are generated (strong wind carries sand to wear the surface of the shell 2), resulting in the unclear right side of the shell 2, the power piece 10 drives the hollow shaft 3 to rotate 180° (through a pre-set program, the control terminal regularly turns on the power piece 10, so that the power piece 10 regularly drives the hollow shaft 3 to rotate 180°), the hollow shaft 3 drives the first flexible block 5 to rotate through the limiting part 4, and the first flexible block 5 drives the shell 2 to rotate. The shell 2 rotates 180°, so that the side of the shell 2 that is contaminated with impurities rotates into the lamp holder 1, the control terminal turns off the power piece 10, and after impurities adhere to the right side of the shell 2 or scratches are generated, a part of the shell 2 hidden in the lamp holder 1 is rotated to the outside of the lamp holder 1, that is, a clear part of the shell 2 is rotated to the outside of the lamp holder 1, so as to ensure the lighting effect of the energy-saving lamp 201.

[0030] When the shell 2 moves to the left due to the impact of strong wind, the shell 2 squeezes the first flexible block 5 and the second flexible block 6, causing the first flexible block 5 and the second flexible block 6 to deform. At the same time, the shell 2 squeezes the sliding frame 7, and the sliding frame 7 squeezes the buffer airbag 8, which also deforms. The elastic part between the sliding frame 7 and the shell 2 shrinks, and the gas in the buffer airbag 8 enters the interior of the first flexible block 5 and the gap between the second flexible block 6 and the lamp holder 1 through the connecting pipe 12 and the chamber 901 at the same time, so that the first flexible block 5 and the second flexible block 6 expand. The first flexible block 5 and the second flexible block 6 clamp the limiting part 4 of the hollow rotating shaft 3, thereby enhancing the stability of the shell 2, reducing the shaking amplitude of the shell 2, and ensuring the lighting stability of the device.

[0031] When the shell 2 is damaged, for example, because the shell 2 is in a windy environment for a long time, it is worn by sand and impacted by impurities carried by the wind, resulting in damage to the shell 2. The gas in the chamber 901 will leak to the outside, and the gas in the buffer airbag 8 will leak into the chamber 901 through the connecting pipe 12. The buffer airbag 8 no longer expands, and the elastic part between the sliding frame 7 and the shell 2 is compressed. The sliding frame 7 squeezes the pressure sensor 11. The pressure sensor 11 is pressurized and turns on the power part 10 through the control terminal. The power part 10 drives the hollow shaft 3 to rotate 180°. Repeat the above steps to rotate the shell 2 180°, and rotate the damaged part on the shell 2 to the lamp holder 1 to reduce the impact of the damage to the shell 2 on the lighting effect of the internal energy-saving lamp 201. After the power part 10 drives the hollow shaft 3 to rotate 180°, the control terminal turns off the power part 10.

[0032] Example 3 This embodiment discloses an energy-saving lighting device for urban roads, which is further improved on the basis of the second embodiment.

[0033] like Figure 7 and Figure 8 As shown, a rotating shaft 13 is rotatably connected inside the hollow rotating shaft 3, and the rotating shaft 13 is detachably connected to the lamp holder 1. The rotating shaft 13 is rotatably connected to the energy-saving lamp 201, and a torsion spring is fixedly connected between the rotating shaft 13 and the energy-saving lamp 201. The energy-saving lamp 201 is supported by the torsion spring to overcome the gravity of the energy-saving lamp 201 itself. After the shell 2 and the inner tank 9 are damaged, if the energy-saving lamp 201 is directly impacted by a strong wind, or even impacted by impurities carried by the strong wind, the energy-saving lamp 201 rotates, and the torsion spring between the rotating shaft 13 and the energy-saving lamp 201 accumulates force. After the strong wind stops, the torsion spring between the rotating shaft 13 and the energy-saving lamp 201 is reset, so that the energy-saving lamp 201 rotates and resets, and the impact on the energy-saving lamp 201 is buffered, thereby reducing the probability of the energy-saving lamp 201 being damaged by the impact.

[0034] Example 4 This embodiment discloses an energy-saving lighting device for urban roads, which is further improved on the basis of the second embodiment.

[0035] like Figure 3-Figure 5 As shown, two scrapers 15 and two cleaning blocks 16 are fixedly connected to the lamp holder 1, and the scrapers 15 and the cleaning blocks 16 are both in contact with the surface of the shell 2. The cleaning block 16 is initially in a force storage state to fit tightly to the surface of the shell 2. The cleaning block 16 is located inside the lamp holder 1, and the scraper 15 is located outside the lamp holder 1. The cleaning block 16 is made of elastic material. During the rotation of the shell 2, the scrapers 15 and the cleaning blocks 16 scrape and wipe the impurities on the surface of the shell 2 respectively. The dry impurities are scraped off by the scrapers 15, and the impurities containing moisture are wiped off by the cleaning blocks 16. At the same time, the dry impurities and the wet impurities are cleaned to maintain the clarity of the shell 2. The elastic coefficient of the cleaning block 16 is smaller than the elastic coefficient of the buffer airbag 8, so that the cleaning block 16 fits tightly to the shell 2, but due to the support of the buffer airbag 8 and the sliding frame 7, the shell 2 will not move to the left.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
