Description

Technical Field

[0001] This invention relates to the field of smart street light technology, and more particularly to a street light pole for use in smart street lights. Background Technology

[0002] As an important infrastructure of smart cities, smart streetlights integrate technologies such as the Internet of Things, sensors, and communications to achieve multi-functional integration of lighting, information collection, traffic management, environmental monitoring, and public services, significantly improving the level of intelligent urban management. The light pole is the supporting component of smart streetlights.

[0003] A search revealed that Chinese patent CN207865321U discloses a street light pole, comprising a hollow cylindrical outer tube and an inner liner tube nested within the outer tube. The outer tube and the inner liner tube are detachably connected by threaded fasteners. This design employs a nested connection of two types of tubing. The outer tube is made of lightweight aluminum alloy, while the inner liner tube is made of steel with high rust resistance. This combination improves the stability and safety of the street light pole, as well as its rust resistance, thereby extending its service life. However, this design still has the following shortcomings in practical use:

[0004] Similar to existing street light poles, the pole proposed in the above solution is a single long pole structure. This type of pole is inconvenient for both the installation and maintenance of street lights, and it is also difficult to transport. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology has the disadvantage of the long light poles, which are inconvenient for installing and transporting light fixtures. To this end, we propose a street light pole for smart street lights.

[0006] To achieve the above objectives, this application adopts the following technical solution: a street light pole for smart street lights, comprising a first light pole and a second light pole, the first light pole and the second light pole being connected by a connecting structure, a housing being fixed on the first light pole, a guide component being provided on the first light pole, threaded sleeves being fixed at the ends of the first light pole and the second light pole that are close to each other, and a buffer component being provided inside the housing, the buffer component comprising a traction structure and a braking structure;

[0007] The connection structure includes a connecting column, one end of which is rotatably connected to a first lamp post, and the other end of which is rotatably connected to a second lamp post. Two sliding sleeves are slidably fitted on the connecting column, and the inner surfaces of the two sliding sleeves are provided with threaded grooves that are adapted to the threaded column. Several notches are opened at the ends of the two sliding sleeves that are close to each other. A locking component is provided on the connecting column.

[0008] Preferably, the locking assembly includes several locking plates, with adjacent locking plates connected by connecting straps, and a lock is provided on two connecting straps located at the ends;

[0009] The lock includes a lock body and a latch. The lock body is fixed to one of the connecting strips, and the latch is fixed to the other connecting strip. When the several locking plates form a cylindrical structure, the lock can be fastened to the latch.

[0010] Preferably, the shape of the card plate is adapted to the shape of the notch.

[0011] Preferably, the traction structure includes a fixed frame, on which a rotatable axle is provided, and a winding wheel is fixedly sleeved on the axle, with a connecting cable wound on the winding wheel.

[0012] Preferably, the braking structure includes a brake disc, which is fixedly sleeved on the wheel axle. A brake plate is provided above the brake disc, and two fixing plates are fixed on the brake plate. Both fixing plates are slidably mounted on a fixing frame. An adjusting screw is provided above the brake plate, which passes through the fixing frame and is threadedly sleeved with the fixing frame.

[0013] Preferably, the brake plate has an arc surface adapted to the brake disc, and the brake plate and the brake disc are in close contact with each other.

[0014] Preferably, the guide assembly includes a mounting bracket, which is fixed to the first lamp post. The mounting bracket is provided with a rotatable rotating plate, and a pulley is installed at the end of the rotating plate. The mounting bracket is provided with two opposite holes, and limit pins are inserted into the two holes.

[0015] Preferably, when the rotating plate is positioned above the limiting pin, the pulley is higher than the top of the first lamp post.

[0016] Preferably, an annular protective bladder is fixed to the top of the second lamp post, and an air supply component is provided on the fixing frame for supplying air into the annular protective bladder;

[0017] The air supply assembly includes a rotating shaft and an air intake hood. The rotating shaft and the axle are connected by a meshing first gear and a second gear. The air intake hood is fixed on a fixed frame. An air intake fan is fixedly sleeved on the rotating shaft and is located inside the air intake hood. One end of the air intake hood is an open structure, and the other end is connected to an exhaust pipe. The end of the exhaust pipe away from the air intake hood is connected to an annular protective bladder. The exhaust pipe is equipped with a one-way flow restriction structure, which restricts gas to only entering the annular protective bladder.

[0018] Preferably, the unidirectional flow-limiting structure includes a fixed ring, and a flow-limiting diaphragm is provided on the side of the fixed ring away from the intake hood. The flow-limiting diaphragm is connected to the fixed ring by two flexible strips, each of which is made of a flexible material.

[0019] The technical effects and advantages of this invention are as follows:

[0020] In this invention, the rotatable second lamp post design replaces the traditional long pole-shaped lamp post structure. When installing or repairing lamps, workers can control the second lamp post to rotate to a position close to the ground, eliminating the need for climbing to heights and reducing work difficulty and safety risks.

[0021] In this invention, a buffer assembly is provided. Before rotating the second lamp post, a series of operations are performed to position the pulley above the top of the first lamp post. The connecting cable is then pulled out and connected to the second lamp post. When the second lamp post is lowered, the connecting cable drives the winding wheel to rotate. The friction between the brake disc and the brake plate on the wheel axle reduces the release speed of the connecting cable, thereby reducing the rotation speed of the second lamp post and allowing it to rotate slowly to a controllable area, thus improving the safety of lowering the lamp post.

[0022] In this invention, an annular protective bladder is fixedly sleeved on the second lamp post. The air supply component supplies air to the second lamp post during its rotation to inflate it. If the brake disc and brake plate fail and the second lamp post goes out of control, the inflated annular protective bladder can protect the lamp and prevent it from falling and being damaged.

[0038] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0039] Reference Figure 1 As shown, the present invention provides a technical solution: a street light pole for smart street lights, including a first light pole 11 and a second light pole 12, the first light pole 11 and the second light pole 12 are connected by a connecting structure, a box 111 is fixed on the first light pole 11, and threaded sleeves 13 are fixed at the ends of the first light pole 11 and the second light pole 12 that are close to each other.

[0040] Reference Figure 2As shown, a guide assembly is provided on the first lamp post 11. The guide assembly includes a mounting bracket 112, which is fixed on the first lamp post 11. A rotatable rotating plate 113 is provided on the mounting bracket 112. A pulley 114 is installed at the end of the rotating plate 113. Two opposite holes are provided on the mounting bracket 112, and a limit pin 115 is inserted into the two holes. When the rotating plate 113 is placed above the limit pin 115, the pulley 114 is higher than the top of the first lamp post 11.

[0041] Reference Figure 5 As shown, the connection structure includes a connecting post 21. One end of the connecting post 21 is rotatably connected to the first lamp post 11, and the other end of the connecting post 21 is rotatably connected to the second lamp post 12. Two sliding sleeves 22 are slidably sleeved on the connecting post 21. The inner surface of the two sliding sleeves 22 is provided with threaded grooves that are compatible with the threaded post. Several notches 23 are opened at the ends of the two sliding sleeves 22 that are close to each other.

[0042] Reference Figure 4 As shown, a locking assembly is provided on the connecting post 21. The locking assembly includes several locking plates 31. Adjacent locking plates 31 are connected by connecting strips 32. The shape of the locking plates 31 is adapted to the shape of the notch 23. A lock 33 is provided on the two connecting strips 32 located at the ends. The lock 33 includes a lock body and a latch. The lock body is fixed on one of the connecting strips 32, and the latch is fixed on the other connecting strip 32. When the several locking plates 31 form a cylindrical structure, the lock 33 can be fastened to the latch.

[0043] The street light pole for smart streetlights proposed in this invention has the functions of facilitating the installation of lighting fixtures and facilitating transportation. Specifically, the main body is composed of a first light pole 11 and a second light pole 12, which are connected by a connecting structure. During transportation, the first light pole 11 and the second light pole 12 form a... Figure 3 As shown in the diagram, the length of the lamp post is halved, which facilitates its transportation. When installing the lamp post, the workers first fix the first lamp post 11 to the ground, then rotate the second lamp post 12 until it is coaxial with the connecting post 21. Next, the workers pull the sliding sleeve 22 near the second lamp post 12 and screw the sliding sleeve 22 onto the threaded sleeve 13 on the second lamp post 12 by rotation. When the sliding sleeve 22 is in place, it connects the connecting post 21 and the second lamp post 12. In this case, the second lamp post 12 is fixed in a coaxial state with the connecting post 21.

[0044] After installing the second lamp post 12, the worker rotates the second lamp post 12 again, making it rotate synchronously with the connecting post 21, until the connecting post 21 rotates to a state coaxial with the first lamp post 11. At this point, the worker can pull the sliding sleeve 22 near the first lamp post 11 and screw the sliding sleeve 22 onto the threaded sleeve 13 on the first lamp post 11 by rotation. When the sliding sleeve 22 is in place, it connects the connecting post 21 and the first lamp post 11. In this case, the first lamp post 11 is fixed in a state coaxial with the connecting post 21. In summary, the two sliding sleeves 22 connect the first lamp post 11, the connecting post 21, and the second lamp post 12, so that the first lamp post 11, the connecting post 21, and the second lamp post 12 together form a... Figure 1 The state shown;

[0045] By setting a rotatable second lamp post 12, when installing or repairing the lamps, the staff can control the second lamp post 12 to rotate to a position close to the ground. This design replaces the traditional long pole-shaped lamp post structure, eliminating the need for staff to climb to a high place to install and repair the streetlights.

[0046] After fixing the positions of the two sliding sleeves 22, the workers install the locking components onto the connecting post 21 to lock the positions of the two sliding sleeves 22. Specifically, the workers wrap several locking plates 31 around the connecting post 21 so that the two ends of the locking plates 31 are respectively engaged in several notches 23 on the two sliding sleeves 22. Finally, the locking plates 31 are locked with the locking device 33. Under the restriction of the locking plates 31, the two sliding sleeves 22 can no longer rotate. When the two sliding sleeves 22 cannot rotate, the constraint of the two sliding sleeves 22 on the first lamp post 11, the connecting post 21 and the second lamp post 12 cannot be released, thereby ensuring the stability of the overall structure of the lamp post.

[0047] Reference Figure 9 As shown, the housing 111 is equipped with a buffer assembly, which includes a traction structure and a braking structure. The traction structure includes a fixed frame 41, on which a rotatable axle 42 is mounted. A winding wheel 43 is fixedly sleeved on the axle 42, and a connecting cable 44 is wound on the winding wheel 43. The braking structure includes a brake disc 51, which is fixedly sleeved on the axle 42. A brake plate 52 is mounted above the brake disc 51. The brake plate 52 has an arc surface that matches the brake disc 51, and the brake plate 52 and the brake disc 51 are in close contact. Two fixed plates 521 are fixed on the brake plate 52, and both fixed plates 521 are slidably mounted on the fixed frame 41. An adjusting screw 53 is mounted above the brake plate 52. The adjusting screw 53 passes through the fixed frame 41 and is threadedly sleeved with the fixed frame 41.

[0048] This invention also includes a buffer assembly. When the lamp needs maintenance, the operator controls the rotation of the second lamp post 12. During this process, the buffer assembly acts on the second lamp post 12, allowing it to rotate slowly and preventing accidents. Specifically, before rotating the second lamp post 12, the operator first removes the limiting pin 115. Without the constraint of the limiting pin 115, the rotating plate 113 can rotate freely. The operator then controls the rotating plate 113 to rotate above the hole position. Finally, the operator reinserts the limiting pin 115 into the hole position, forming... Figure 12 As shown, in this state, the pulley 114 is positioned above the top of the first lamp post 11. Further, the worker pulls out the connecting cable 44 and connects the connecting cable 44 to the second lamp post 12, while simultaneously allowing the connecting cable 44 to pass around the pulley 114, using the pulley 114 to provide guidance for the connecting cable 44.

[0049] After completing the above operations, the worker releases the constraint of the sliding sleeve 22 on the second lamp post 12. Without the constraint of the sliding sleeve 22, the second lamp post 12 can rotate. During the process of lowering the second lamp post 12, the second lamp post 12 can pull the connecting cable 44, causing the connecting cable 44 to unwind from the winding wheel 43. At this time, the connecting cable 44 can drive the winding wheel 43 to rotate, and the wheel axle 42 connected to the winding wheel 43 will rotate accordingly. When the wheel axle 42 rotates, the brake disc 51 on it rotates synchronously. During this process, the brake plate 52 provides a braking effect for the brake disc 51. The friction between the brake plate 52 and the brake disc 51 can reduce the release speed of the connecting cable 44, thereby reducing the rotation speed of the second lamp post 12. This design allows the second lamp post 12 to slowly rotate to a controllable area on the ground. This design enhances safety when lowering the second lamp post 12. Additionally, the mounting bracket 41 is equipped with a rotatable adjusting screw 53. When the adjusting screw 53 moves downwards, it presses down on the brake plate 52, increasing the pressure exerted by the brake plate 52 on the brake disc 51, thereby further slowing the rotation speed of the second lamp post 12. Conversely, when the adjusting screw 53 moves upwards, the friction between the brake plate 52 and the brake disc 51 decreases, increasing the rotation speed of the second lamp post 12. Therefore, workers can control the rotation speed of the second lamp post 12 by rotating the adjusting screw 53.

[0050] Reference Figure 1 and Figure 10As shown, an annular protective bladder 121 is fixed to the top of the second lamp post 12. An air supply assembly is installed on the mounting bracket 41 to supply air into the annular protective bladder 121. The air supply assembly includes a rotating shaft 61 and an air intake hood 64. The rotating shaft 61 and the axle 42 are connected by a meshing first gear 62 and a second gear 63. The air intake hood 64 is fixed to the mounting bracket 41. An air intake fan 65 is fixedly sleeved on the rotating shaft 61 and is located inside the air intake hood 64. One end of the air intake hood 64 is an open structure. One end is connected to an exhaust pipe 66. The end of the exhaust pipe 66 away from the inhalation hood 64 is connected to the annular protective bladder 121. The exhaust pipe 66 is equipped with a one-way flow restriction structure. The one-way flow restriction structure restricts gas to enter only the annular protective bladder 121. The one-way flow restriction structure includes a fixed ring 661. A flow restriction diaphragm 662 is provided on the side of the fixed ring 661 away from the inhalation hood 64. The flow restriction diaphragm 662 and the fixed ring 661 are connected by two flexible strips 663. Each flexible strip 663 is made of flexible material.

[0051] In addition, the present invention provides dual protection for the second lamp post 12. Specifically, an annular protective bladder 121 is fixedly sleeved on the second lamp post 12. During the rotation of the second lamp post 12, the air supply component supplies air to the annular protective bladder 121, causing the annular protective bladder 121 to inflate. This design is used to deal with special situations, such as the failure of the brake disc 51 and brake plate 52. If the second lamp post 12 loses control during rotation, the annular protective bladder 121 in the inflated state can protect the lamps on the second lamp post 12 and prevent the lamps from falling and being damaged. Specifically, when the axle 42 rotates, it can drive the rotating shaft 61 to rotate through the meshing first gear 62 and second gear 63. When the rotating shaft 61 rotates, it can drive the suction fan 65 to rotate. When the suction fan 65 rotates, it performs a suction action and discharges the gas into the exhaust pipe 66 through the suction hood 64. Finally, the gas can enter the interior of the annular protective bladder 121 through the exhaust pipe 66, causing the annular protective bladder 121 to inflate.

[0052] The exhaust pipe 66 is equipped with a one-way flow-limiting structure, which restricts the flow direction of the gas, allowing the gas to smoothly enter the annular protective bladder 121. Specifically, as follows: Figure 11 and Figure 13 As shown, in the initial state, under the elastic force of the two flexible bands 663, the flow-limiting diaphragm 662 is in a position that fits against the annulus of the fixed ring 661. When the airflow enters the exhaust pipe 66, the airflow can push the flow-limiting diaphragm 662, causing the flow-limiting diaphragm 662 to deform and form as shown in the figure. Figure 13As shown, the airflow can pass through the opening of the fixed ring 661 and flow through the exhaust pipe 66. When the airflow flows back, the gas will push the flow-limiting diaphragm 662, causing the flow-limiting diaphragm 662 to adhere to the fixed ring 661 and prevent the gas from flowing back. Therefore, the flow-limiting diaphragm 662 restricts the gas to enter the annular protective bladder 121, allowing the annular protective bladder 121 to inflate smoothly.

[0053] Working principle:

[0054] During transportation, the first lamp post 11 and the second lamp post 12 are positioned in a specific manner, with the lamp post length shortened by half for easier transport. During installation, the first lamp post 11 is first fixed to the ground. The second lamp post 12 is rotated to make it coaxial with the connecting column 21. The sliding sleeve 22 near the second lamp post 12 is pulled and screwed onto the threaded sleeve 13 of the second lamp post 12. At this time, the sliding sleeve 22 fixes the connecting column 21 and the second lamp post 12, keeping the second lamp post 12 coaxial with the connecting column 21. Then, the second lamp post 12 is rotated again to make it rotate synchronously with the connecting column 21 until the connecting column 21 is coaxial with the first lamp post 11. The sliding sleeve 22 near the first lamp post 11 is then pulled and screwed onto the threaded sleeve 13 of the first lamp post 11, fixing the first lamp post 11 in a coaxial state with the connecting column 21. The two sliding sleeves 22 together connect the first lamp post 11, the connecting column 21, and the second lamp post 12, forming a complete lamp post structure.

[0055] When the lamps need to be installed or repaired, since the second lamp post 12 can be rotated, the staff can control it to rotate to a position close to the ground without having to climb to a height. After the two sliding sleeves 22 are installed, several clamping plates 31 are wrapped around the connecting column 21 so that the two ends of the clamping plates 31 are engaged in the notches 23 of the two sliding sleeves 22. Then, the clamping plates 31 are locked with the locking device 33 to restrict the rotation of the sliding sleeves 22 and ensure the overall stability of the lamp post structure.

[0056] When lowering the second lamp post 12 for maintenance, first remove the limiting pin 115, rotate the rotating plate 113 on the first lamp post 11 so that the pulley 114 is above the top of the first lamp post 11, reinsert the limiting pin 115, pull out the connecting cable 44 and connect it to the second lamp post 12, and at the same time let the connecting cable 44 pass over the pulley 114. Then release the constraint of the sliding sleeve 22 on the second lamp post 12. During the lowering of the second lamp post 12, the second lamp post 12 pulls the connecting cable 44, causing the connecting cable 44 to unwind from the winding wheel 43 and drive the winding wheel. As the wheel 43 rotates, the axle 42 connected to the winding wheel 43 rotates accordingly, and the brake disc 51 on the axle 42 also rotates synchronously. At this time, the friction between the brake plate 52 and the brake disc 51 reduces the release speed of the connecting cable 44, thereby reducing the rotation speed of the second lamp post 12. The staff can also rotate the adjusting screw 53 to press down the brake plate 52, changing the pressure of the brake plate 52 on the brake disc 51, thereby controlling the rotation speed of the second lamp post 12 and allowing the second lamp post 12 to slowly rotate to a controllable area on the ground, improving the safety of lowering it.

[0057] Meanwhile, to address special circumstances such as brake disc 51 and brake plate 52 failure, the light pole is equipped with double protection. An annular protective bladder 121 is fixed at the top of the second light pole 12. When the wheel axle 42 rotates, it drives the rotating shaft 61 to rotate through the meshing first gear 62 and second gear 63. The suction fan 65 on the rotating shaft 61 rotates to perform a suction action, and the gas is discharged into the exhaust pipe 66 through the suction hood 64, and finally enters the annular protective bladder 121 to inflate it. A one-way flow limiting structure is set in the exhaust pipe 66. In the initial state, there are two flexible belts 663 Under the elastic force, the flow-limiting diaphragm 662 fits into the ring opening of the fixing ring 661. When the airflow enters the exhaust pipe 66, it pushes the flow-limiting diaphragm 662 to deform, and the airflow can pass through the ring opening of the fixing ring 661 and flow through the exhaust pipe 66. When the airflow flows back, the gas pushes the flow-limiting diaphragm 662 to fit into the fixing ring 661, preventing the gas from flowing back and ensuring that the gas can only enter the annular protective bladder 121, so that the annular protective bladder 121 can be smoothly inflated. If the second lamp post 12 is out of control, the inflated annular protective bladder 121 can protect the lamp and prevent the lamp from falling and being damaged.

[0058] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
