Description

Technical Field

[0001] The present invention belongs to the technical field of solar street lamps, and specifically relates to an outdoor solar street lamp. Background Art

[0002] As a lighting device driven by new energy, solar street lamps greatly reduce the burden of power supply, conform to the concept of green energy environmental protection, and have the characteristics of sustainable development. Solar street lamps are provided with solar panels, which receive direct sunlight and store the generated electric energy in a storage battery. When it gets dark, the storage battery provides power for the street lamp, thus realizing the self-supply of electric power for the street lamp. In the prior art, the column of the solar street lamp is installed on the road surface through embedded parts. When encountering a vehicle impact, due to the limited structural strength of the column itself, it is easy to fall down. At this time, since the solar panel used for power generation lacks corresponding protection, the falling of the column caused by a violent vehicle impact may cause damage to the solar panel. In the prior art, for protecting against such extreme emergencies, measures such as strengthening the column or preventing it from falling are generally adopted, but these are all too passive. The kinetic energy and destructiveness generated by a vehicle hitting at high speed are extremely large, and the column will basically collapse in this case. Moreover, the above protection methods will increase the manufacturing cost of the column, and the peripheral anti-falling measures are also not conducive to the maintenance of the equipment. Therefore, there is an urgent need for an outdoor solar street lamp that can provide effective protection in case of emergencies. Summary of the Invention

[0003] The purpose of the present invention is to provide an outdoor solar street lamp to solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention provides the following technical solution: An outdoor solar street lamp, comprising a column, a lamp body and a top plate. A bracket is installed on the top of the top plate, and a photovoltaic panel is installed on the top of the bracket. The inside of the column is hollow. An air column communicating with the column is fixedly installed on the top of the top plate. An airbag is fixedly connected to the outer side of the photovoltaic panel. A connecting pipe is installed in communication between the air column and the airbag. A sealing cylinder is installed in communication at the bottom of the top plate. A piston is hermetically sleeved inside the sealing cylinder. A fixed cylinder is installed at the bottom of the inner wall of the column. A first spring and a telescopic column are sequentially movably sleeved inside the fixed cylinder from bottom to top. The two ends of the first spring are elastically connected to the telescopic column and the fixed cylinder respectively. The top end of the telescopic column is fixedly connected to a fixed block. The inner wall of the column is sequentially fixedly installed with a placement ring, a support ring and a fixed ring above the fixed cylinder from bottom to top. A plurality of placement cavities are formed inside the placement ring. A sealing ring communicating with the placement cavity is formed on the inner ring surface of the placement ring. A sealing column is hermetically sleeved inside the sealing ring. A limiting block is fixedly connected to the outer end of the sealing column. A plurality of the limiting blocks are equidistantly adapted to abut against the outer surface of the fixed block. A plurality of card slots communicating with the placement cavity are formed on the top of the placement ring. A card plate is hermetically clamped inside the card slot. The inner cavity of the placement cavity is filled with transmission fluid, and a third spring and a sealing head located at one end of the card plate are hermetically sleeved. The bottom of the fixed ring is elastically connected to a second spring. The bottom end of the second spring is elastically connected to a sliding ring and a connecting ring. The bottom of the connecting ring is fixedly connected to the card plate. A plurality of sliders are slidably installed on the top of the support ring. The outer surfaces of the sliders and the sliding ring are mutually adapted to abut against each other.

[0005] As a preferred solution of the present invention, the shape of the fixed block is frustum-shaped. The number of the placement cavities, the sealing columns and the limiting blocks is four. The four limiting blocks form a closed circular ring structure and limit the fixed block downward.

[0006] As a preferred solution of the present invention, the card plate divides the inner cavity of the placement cavity into a liquid storage area and a buffer area. The liquid storage area is located at the inner side end of the card plate and the sealing column. The transmission fluid is located in the liquid storage area. The third spring and the sealing head are both located in the buffer area. The two ends of the third spring are elastically connected to the placement cavity and the sealing head respectively. The sealing head abuts against the card plate.

[0007] As a preferred solution of the present invention, the cross-sectional shape of the card plate is "U" shaped. The bottom of the card plate is adapted to abut against the bottom of the placement cavity. The top of the card plate protrudes above the top of the placement ring.

[0008] As a preferred embodiment of the present invention, a plurality of limiting strips are fixedly connected to the top of the support ring. The number of the sliders is the same as that of the limiting strips. A chute is formed at the bottom of the slider. The limiting strips are slidably installed in the chute. The slider can move horizontally towards the center of the support ring under the limitation of the limiting strips.

[0009] As a preferred embodiment of the present invention, the connecting ring is fixedly connected to the bottom of the sliding ring, and the connecting ring is located between the placing ring and the support ring.

[0010] As a preferred embodiment of the present invention, the outer surface of the slider is adapted to abut against the inner wall of the column, and the slider is made of solid cast iron material.

[0011] As a preferred embodiment of the present invention, the diameter value of the bottom end of the fixed block is smaller than the inner diameter value of the sliding ring. An inclined surface is formed on the upper part of the outer surface of the sliding ring and is adapted to abut against the top of the slider.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The internal structure of the column of this street lamp is redesigned to enable it to generate a synchronous protection function for the airbag when impacted by a vehicle. The device is provided with a fixed cylinder at the bottom of the inner wall of the column. A spring I compressed to the limit is installed inside it. The spring I releases elastic potential energy upward and pushes the telescopic column, the fixed block and the piston to move upward continuously, and generates air pressure inside the sealing cylinder. Through the air column and the connecting pipe, it acts on the inside of the airbag, so that the airbag can quickly expand in a short time and provide protection for the airbag. The release of the elastic potential energy of the spring I is restricted by four groups of limiting blocks evenly distributed in a circle. The limiting blocks are connected to the sealing column and are hermetically abutted against the transmission fluid filled in the inner cavity of the placing ring through the sealing ring. When the clamping plate is completely clamped into the placing cavity, the transmission fluid is blocked in the liquid storage area. At this time, the established positions of the sealing column and the limiting blocks are maintained through the non-compressible characteristic of the transmission fluid. The four groups of limiting blocks form a circular ring structure and limit the fixed block downward, so that the fixed block cannot move upward. This design helps to improve the reliability of the self-protection of the street lamp.

[0014] 2. Then, press down on the sliding ring and the connecting ring through the fixed ring and the second spring elastically connected to its bottom. The bottom of the connecting ring is connected to the clamping plate. Usually, the elastic force of the second spring is transmitted to the clamping plate through the sliding ring and the connecting ring, making the clamping plate firmly stuck in the placement cavity and preventing the transmission fluid in the liquid storage area from flowing into the buffer area, enabling the limiting block to abut against the fixed block for limiting. By providing a support ring between the sliding ring and the connecting ring, multiple sets of sliders are slidably installed on its top. The sliding grooves opened at the bottoms of the sliders are slidably adapted to the limiting strips fixedly connected to the top of the support ring. The inclined surfaces between the sliders and the outer surface of the sliding ring are mutually adapted and abutted. When the column is hit by a vehicle and quickly topples, at this time, one of the multiple sets of independent sliders can move towards the side close to the axis of the piston under the action of inertia. This set of sliders is located opposite to the toppling direction of the column. The moving slider starts to press on the sliding ring, causing the sliding ring to drive the connecting ring and the clamping plate to move upward, and connecting the buffer area and the liquid storage area. At this time, the transmission fluid starts to flow into the buffer area, the first spring starts to release its elastic potential energy, and pushes the fixed block and the piston upward. The limiting block then drives the sealing column to move towards the inside of the sealing ring under the push of the fixed block. The sealing head is pushed by the transmission fluid and compresses the third spring. At this time, the piston can quickly move upward, generating high-pressure air flow in the inner cavity of the sealing cylinder to assist the airbag in inflating. The above design uses the inertia of the sliders to automatically identify whether the column is in a high-speed movement or toppling state, thus making the inflation operation of the entire airbag fully automated.

[0015] 3. The function of dividing the inner cavity of the placement cavity designed in this device into a liquid storage area and a buffer area is as follows: When the clamping plate is hermetically clamped in the placement cavity, the liquid storage area and the buffer area are hermetically isolated. Even if the first spring pushes the telescopic column and the fixed block upward and transmits the pressure to the limiting block, causing the limiting block to push the sealing column towards the inside of the placement cavity, at this time, the transmission fluid fills the entire liquid storage area and cannot enter the buffer area. Due to the non-compressible property of the transmission fluid, the limiting block does not move and just limits the fixed block, offsetting the elastic force from the first spring. When the slider pushes the sliding ring, the connecting ring and the clamping plate upward, the liquid storage area and the buffer area are connected, and the transmission fluid can flow into the buffer area and push the sealing head, compressing the third spring. At this time, the fluidity of the transmission fluid cannot provide a role for the limiting block to abut against the fixed block for limiting, that is, the limiting effect of the limiting block on the fixed block is released.

[0030] As Figures 1 to 12 shown, an embodiment of the present invention provides an outdoor solar street lamp, including a column 1, a lamp body 2 and a top plate 3. A bracket 4 is installed on the top of the top plate 3, and a photovoltaic panel 5 is installed on the top of the bracket 4. The inside of the column 1 is hollow. An air column 7 communicated with the column 1 is fixedly installed on the top of the top plate 3. An airbag 6 is fixedly connected to the outer side surface of the photovoltaic panel 5. A communication pipe 8 is installed in communication between the air column 7 and the airbag 6. A sealing cylinder 9 is communicated and installed at the bottom of the top plate 3. A piston 10 is hermetically sleeved inside the sealing cylinder 9. A fixed cylinder 11 is installed at the bottom of the inner wall of the column 1. A first spring 12 and a telescopic column 13 are sequentially movably sleeved inside the fixed cylinder 11 from bottom to top. The two ends of the first spring 12 are elastically connected to the telescopic column 13 and the fixed cylinder 11 respectively. The top end of the telescopic column 13 is fixedly connected to a fixed block 14. The inner wall of the column 1 is fixedly installed with a placement ring 23, a support ring 18 and a fixed ring 15 located above the fixed cylinder 11 from bottom to top in sequence. A plurality of placement cavities 24 are formed inside the placement ring 23. A sealing ring 25 communicated with the placement cavity 24 is formed on the inner ring surface of the placement ring 23. A sealing column 26 is hermetically sleeved inside the sealing ring 25. The outer end of the sealing column 26 is fixedly connected to a limiting block 27. A plurality of limiting blocks 27 are equidistantly and adaptively abutted against the outer surface of the fixed block 14. A plurality of card slots 28 communicated with the placement cavity 24 are formed on the top of the placement ring 23. A card plate 29 is hermetically clamped inside the card slot 28. The inner cavity of the placement cavity 24 is filled with a transmission fluid 30, and a third spring 31 and a sealing head 32 located at one end of the card plate 29 are hermetically sleeved. A second spring 16 is elastically connected to the bottom of the fixed ring 15. The bottom end of the second spring 16 is elastically connected to a sliding ring 17 and a connecting ring 22. The bottom of the connecting ring 22 is fixedly connected to the card plate 29. A plurality of sliders 20 are slidably installed on the top of the support ring 18. The outer surfaces of the sliders 20 and the sliding ring 17 are mutually adapted and abutted;

[0031] This street lamp has redesigned the interior of the upright column 1 so that it can generate a synchronous protection function for the airbag 6 when the vehicle impacts. The device is provided with a fixed cylinder 11 at the bottom of the inner wall of the upright column 1. A spring 12 compressed to the limit is installed inside it. The spring 12 releases elastic potential energy upward and pushes the telescopic column 13, the fixed block 14 and the piston 10 to move upward continuously, and generates air pressure inside the sealed cylinder 9. Through the air column 7 and the connecting pipe 8, it acts on the inside of the airbag 6, so that the airbag 6 can expand rapidly in a short time and provide protection for the airbag 6. Restricting the release of elastic potential energy of the spring 12 are four groups of limit blocks 27 evenly distributed in a circle. The limit blocks 27 are connected to the sealing column 26 and are hermetically abutted against the transmission fluid 30 filled in the inner cavity of the placement ring 23 through the sealing ring 25. When the clamping plate 29 is completely inserted into the placement cavity 24, the transmission fluid 30 is blocked in the liquid storage area. At this time, the established positions of the sealing column 26 and the limit blocks 27 are maintained through the non-compressible characteristic of the transmission fluid 30. The four groups of limit blocks 27 form a circular ring structure and limit the fixed block 14 downward, so that the fixed block 14 cannot move upward. This design helps to improve the reliability of the self-protection of the street lamp.

[0032] Then, by providing a fixed ring 15 and a spring 16 elastically connected to its bottom to press down on the sliding ring 17 and the connecting ring 22. The bottom of the connecting ring 22 is connected to the clamping plate 29. Usually, the elastic force of the spring 16 is transmitted to the clamping plate 29 through the sliding ring 17 and the connecting ring 22, so that the clamping plate 29 is firmly stuck in the placement cavity 24 and prevents the transmission fluid 30 in the liquid storage area from flowing into the buffer area, so that the limit block 27 can abut against and limit the fixed block 14. By providing a support ring 18 between the sliding ring 17 and the connecting ring 22, multiple sliders 20 are slidably installed on its top. The chute 21 opened at the bottom of the slider 20 is slidably adapted to the limit strip 19 fixedly connected to the top of the support ring 18. The inclined surfaces between the slider 20 and the outer surface of the sliding ring 17 are mutually adapted and abutted. When the upright column 1 is impacted by a vehicle and quickly topples over, at this time, one of the multiple independent sliders 20 can move toward the side close to the axis of the piston 10 under the action of inertia. This group of sliders 20 is located on the opposite side of the toppling direction of the upright column 1. The moving slider 20 starts to press on the sliding ring 17, so that the sliding ring 17 drives the connecting ring 22 and the clamping plate 29 to move upward, and connects the buffer area and the liquid storage area. At this time, the transmission fluid 30 starts to flow into the buffer area, and the spring 12 starts to release elastic potential energy and pushes the fixed block 14 and the piston 10 upward. The limit block 27 drives the sealing column 26 to move toward the inside of the sealing ring 25 under the push of the fixed block 14. The sealing head 32 is pushed by the transmission fluid 30 and compresses the spring 31. At this time, the piston 10 can move upward quickly, generating high-pressure air flow in the inner cavity of the sealed cylinder 9 to assist the airbag 6 to expand. The above design uses the inertia of the slider 20 to automatically identify whether the upright column 1 is in a high-speed movement or toppling state, so that the inflation operation of the entire airbag 6 is fully automated.

[0033] Among them, the fixed block 14 is frustum-shaped. The number of the placement cavities 24, the sealing columns 26, and the limiting blocks 27 is four groups. The four groups of limiting blocks 27 form a closed ring structure and limit the fixed block 14 downward.

[0034] The fixed block 14 is frustum-shaped, and the size difference between its smaller upper end and larger lower end just abuts and fits with multiple groups of limiting blocks 27. When the sealing column 26 cannot move towards the inner side of the sealing ring 25, the closed ring structure formed by the four groups of limiting blocks 27 just limits the fixed block 14 downward, so that the fixed block 14 cannot move upward under the elastic force of the first spring 12.

[0035] Among them, the clamping plate 29 divides the inner cavity of the placement cavity 24 into a liquid storage area and a buffer area. The liquid storage area is located inside the clamping plate 29 and the inner end of the sealing column 26. The transmission liquid 30 is located in the liquid storage area. The third spring 31 and the sealing head 32 are both located in the buffer area. The two ends of the third spring 31 are elastically connected to the placement cavity 24 and the sealing head 32 respectively, and the sealing head 32 abuts against the clamping plate 29.

[0036] The function of dividing the inner cavity of the designed placement cavity 24 of this device into a liquid storage area and a buffer area is as follows: when the clamping plate 29 is hermetically clamped in the placement cavity 24, the liquid storage area and the buffer area are hermetically isolated. Even if the first spring 12 pushes the telescopic column 13 and the fixed block 14 upward and transmits the pressure to the limiting block 27, making the limiting block 27 push the sealing column 26 towards the inner side of the placement cavity 24. At this time, the transmission liquid 30 fills the entire liquid storage area and cannot enter the buffer area. Due to the non-compressible characteristic of the transmission liquid 30, the limiting block 27 does not move and just limits the fixed block 14, offsetting the elastic force from the first spring 12. When the slider 20 pushes the sliding ring 17, the connecting ring 22, and the clamping plate 29 upward, the liquid storage area and the buffer area are communicated, and the transmission liquid 30 can flow into the buffer area and push the sealing head 32, compressing the third spring 31. At this time, the fluidity of the transmission liquid 30 cannot provide a function for the limiting block 27 to abut and limit the fixed block 14, that is, the limiting effect of the limiting block 27 on the fixed block 14 is released.

[0037] Among them, the cross-sectional shape of the clamping plate 29 is "U" - shaped. The bottom of the clamping plate 29 abuts and fits with the bottom of the placement cavity 24, and the top of the clamping plate 29 protrudes from the top of the placement ring 23.

[0038] The bottom of the clamping plate 29 just abuts and fits with the bottom of the placement cavity 24, thus forming a seal under high pressure. The non - compressibility of the transmission liquid 30 is combined with the sealing column 26 and the limiting block 27 to rigidly limit the fixed block 14.

[0039] Among them, multiple groups of limiting bars 19 are fixedly connected to the top of the support ring 18. The number of sliders 20 is the same as that of the limiting bars 19. A chute 21 is opened at the bottom of the slider 20, and the limiting bar 19 is slidably installed in the chute 21. The slider 20 can move horizontally towards the center of the support ring 18 under the limitation of the limiting bar 19;

[0040] The support ring 18 is used to slidably support the slider 20. The slider 20 has multiple directions and covers the entire outer periphery of the sliding ring 17. No matter which direction the upright column 1 topples, there will be a group of sliders 20 that can move in the corresponding direction.

[0041] Among them, the connecting ring 22 is fixedly connected to the bottom of the sliding ring 17, and the connecting ring 22 is located between the placing ring 23 and the support ring 18;

[0042] The connecting ring 22 needs to move upward with the sliding ring 17, so there needs to be some distance between it and the stationary support ring 18.

[0043] Among them, the outer surface of the slider 20 is adaptively abutted against the inner wall of the upright column 1, and the slider 20 is made of solid cast iron material;

[0044] The slider 20 abuts against the inclined surface of the outer surface of the sliding ring 17, so that the movement of the slider 20 along the radial line of the sliding ring 17 can be converted into the movement of the sliding ring 17 along its own axis. The slider 20 made of solid cast iron has a high mass, which means its inertia is also large, helping to improve the sensitivity of the triggering of the protection function.

[0045] Among them, the diameter value of the bottom end of the fixed block 14 is smaller than the inner diameter value of the sliding ring 17. An inclined surface is opened on the upper part of the outer surface of the sliding ring 17 and is adaptively abutted against the top of the slider 20;

[0046] The fixed block 14 needs to move through the sliding ring 17. In order to prevent jamming between the two during relative movement, the difference in dimensions needs to be considered.

[0047] Working principle:

[0048] First, this device is installed inside by installing embedded parts at the bottom. When the vehicle gets out of control and hits this street lamp at a high speed, the main body of the upright column 1 starts to separate from the embedded parts in the ground, and the whole topples, and the photovoltaic panel 5 faces the side where the toppling occurs;

[0049] Then, due to the strong impact, the upright column 1 topples quickly, causing the slider 20 in the upright column 1 to move horizontally towards the center side of the piston 10 under the action of inertia, as Figure 2 、 Figure 3As shown, assume that the vehicle impacts from the right side of the column 1, causing the entire column 1 to tilt to the left. At this time, in the column 1, the slider 20 located on the leftmost side will have a relative movement tendency to the right with respect to the sliding ring 17 and the support ring 18, and the direction of this relative movement tendency is to the right along the diameter line of the support ring 18.

[0050] Then, in the reference system between the placement ring 23 and the fixed ring 15 in the inner cavity of the column 1, the slider 20 on the left side continues to move to the right, so that the inclined surface at the top of the slider 20 fits and abuts against the inclined surface of the outer surface of the sliding ring 17. Under the action of the slider 20, the sliding ring 17 moves upward relative to the support ring 18 and compresses the second spring 16. At the same time, it drives the clamping plate 29 to move upward. When the gap between the clamping plate 29 and the inner wall of the placement cavity 24 gradually increases and enables the transmission fluid 30 to enter the buffer area, the sealing head 32 abuts against the transmission fluid 30. At this time, the telescopic column 13 and the fixed block 14 push the limit block 27 upward under the elastic force of the first spring 12, so that the limit block 27 drives the sealing column 26 to push the transmission fluid 30 located in the liquid storage area, enabling the transmission fluid 30 to enter the buffer area and push the sealing head 32, compressing the third spring 31. At this time, the limit block 27 loses the horizontal limiting function for the fixed block 14, and the fixed block 14 drives the piston 10 to continue moving upward, and generates air pressure through the space inside the sealing cylinder 9, and fills the airbag 6 through the air column 7 and the connecting pipe 8, so that the airbag 6 is quickly filled and wraps around the outside of the photovoltaic panel 5 to form a protection for the photovoltaic panel 5.
