Description

Technical Field

[0001] The present application relates to the technical field of street lamps, and in particular to an anti-dumping LED lighting street lamp and an installation method thereof. Background Art

[0002] Street lamps are one of the most common lamps in people's production and life, and are also one of the important infrastructures for urban lighting.

[0003] Existing street lamps generally include a lamp holder, a lamp pole and a lamp head. The lamp holder is buried in the roadbed on one side of the road, the lamp pole is erected on the roadbed, and the lamp head is arranged at the top of the lamp pole and can illuminate the road. Since the lamp head is heavy and the lamp pole is long, workers must ensure that the lamp pole is erected vertically on the roadbed when installing the street lamp. Otherwise, when the verticality deviation between the lamp pole and the ground is too large, the lamp pole may be bent or crushed by the lamp head on its top, endangering the buildings and pedestrians around the street lamp.

[0004] However, since street lamps are installed next to the road, it is common for out-of-control vehicles on the road to scrape or collide with lamp poles. When the lamp pole is hit, not only will the connection between the lamp holder and the roadbed become loose, but the upper part of the lamp pole will also tilt toward the ground, making it very likely that the street lamp will fall onto the sidewalk next to the road before maintenance personnel arrive, endangering the buildings and pedestrians around the street lamp.

[0005] In view of this, it is necessary to provide an anti-dumping LED lighting street lamp and an installation method thereof. Summary of the invention

[0006] In order to solve the problem that the existing street lamps are likely to topple over before the maintenance personnel arrive after being hit by a vehicle, the present application provides an anti-topple LED lighting street lamp and an installation method thereof.

[0007] In the first aspect, the present application provides an anti-dumping LED lighting street lamp, which adopts the following technical solution: comprising a lamp holder, a lamp pole, a lamp head, a telescopic rod and a driving assembly, wherein the lamp holder is buried in the roadbed on one side of the road, the bottom end of the lamp pole is connected to the lamp holder, and the lamp head is arranged at the top end of the lamp pole;

[0008] The telescopic rod comprises an outer tube and an inner rod, the top end of the outer tube is hinged on the side of the lamp pole away from the road, the bottom end of the outer tube extends downward and is provided with a tube opening, the top end of the inner rod passes through the tube opening and is inserted into the outer tube and can slide along the inner wall of the outer tube, and a clamping piece is provided at the tube opening;

[0009] The driving assembly is transmission-connected to the inner rod, and when the hinge between the outer tube and the lamp pole tilts away from the road, the driving assembly can drive the top end of the inner rod to approach and engage with the engaging piece, and the bottom end of the inner rod abuts against the road surface.

[0010] By adopting the above technical solution, when an out-of-control vehicle on the road scrapes or collides with the side of the lamp pole close to the road, the part of the lamp pole above the collision point will tilt away from the road. At this time, the driving assembly will drive the inner rod to extend out of the outer tube and make the top of the inner rod engage with the clamping piece at the mouth of the outer tube, while the bottom end of the inner rod abuts against the road surface, so that the telescopic rod can extend and abut against the road surface, thereby supporting the lamp pole through the telescopic rod, making it difficult for the lamp pole to topple over before the maintenance personnel arrive, thereby protecting the buildings and pedestrians around the anti-topple LED lighting street lamp.

[0011] Specifically, the driving assembly includes a pressure supply member and a control member, a mounting hole is provided on the rod body of the lamp pole, a mounting protrusion is provided on one side wall of the outer tube, the mounting protrusion is inserted into the mounting hole and hinged with the inner wall of the mounting hole, a piston is provided on the top of the inner rod, the pressure supply member is provided on the mounting protrusion, a connecting hole connected to the pressure supply member is provided on the inner top wall of the outer tube, and the pressure supply member can apply pressure to the inner part of the outer tube through the connecting hole and drive the piston to move downward;

[0012] The control member is connected to the communication hole. When the lamp pole is perpendicular to the ground plane, the control member can block the communication hole. When the lamp pole is tilted, the control member can open the communication hole.

[0013] By adopting the above technical solution, when the lamp pole is perpendicular to the ground plane, the control component will block the connecting hole; when the lamp pole is tilted, the control component will open the connecting hole so that the pressure supply component can apply pressure to the outer tube through the connecting hole, thereby driving the piston and the inner rod to move downward, thereby extending the telescopic rod and contacting the ground.

[0014] Furthermore, the pressure supply part is a high-pressure gas tank, which has an external thread at the tank mouth, an air receiving groove on the mounting protrusion, an internal thread matching the external thread on the side wall of the air receiving groove, and a side opening of the connecting hole is provided on a side wall of the air receiving groove away from the groove, and a gas nozzle matching the pressure supply part is provided in the side opening of the connecting hole.

[0015] By adopting the above technical solution, the internal thread can cooperate with the external thread to connect the high-pressure gas tank to the mounting protrusion, so that the high-pressure gas in the high-pressure gas tank can enter the connecting hole through the gas nozzle.

[0016] Further, the control member includes a valve core and a bent rod, a receiving groove is provided on the hole wall of the communicating hole, the valve core is arranged in the receiving groove, a connecting hole is provided on the top wall of the receiving groove, one end of the bent rod passes through the connecting hole and extends into the receiving groove and is connected to the valve core, the other end of the bent rod abuts against the top wall of the mounting hole, and a fold is provided at the bending part of the bent rod;

[0017] When the lamp pole is perpendicular to the ground plane, the bent rod abuts the valve core against the wall of the connecting hole so that the valve core cuts off the airflow in the connecting hole. When the lamp pole is tilted, the bottom end of the telescopic rod rotates away from the lamp pole and breaks the bent rod at its own fold, and the valve core is pushed into the accommodating groove by the airflow in the connecting hole.

[0018] By adopting the above technical solution, when the lamp pole is perpendicular to the ground plane, one end of the bent rod will abut against the top wall of the mounting hole, and the other end of the bent rod will abut the valve core against the hole wall of the connecting hole, so that the valve core remains in a state of cutting off the airflow in the connecting hole; when the lamp pole is tilted, since the top of the telescopic rod is hinged to the lamp pole, the bottom end of the telescopic rod will rotate away from the lamp pole under the action of its own weight, so that one end of the bent rod inserted into the connecting hole can move toward the direction close to the other end of the bent rod and break the bent rod from its own fold, so that the airflow in the connecting hole can push the valve core into the receiving groove, and then the airflow in the connecting hole can enter the outer cylinder.

[0019] Furthermore, the control component includes a tilt sensor, an electric-controlled valve and a controller, the tilt sensor is arranged on the lamp pole and can detect the tilt angle between the lamp pole and the ground plane, and the tilt sensor is electrically connected to the controller and can feed back the tilt angle to the controller, the electric-controlled valve is arranged in the connecting hole, and the controller is electrically connected to the electric-controlled valve and can control the switch of the electric-controlled valve according to the tilt angle.

[0020] By adopting the above technical solution, the tilt sensor can detect the tilt angle between the lamp pole and the ground plane. When the tilt angle is 90 degrees, the controller will control the electric control valve to always remain in a closed state; when the tilt angle is not 90 degrees, the controller will control the electric control valve to open so that the airflow in the connecting hole can enter the outer tube.

[0021] Specifically, a plurality of connecting plates are arranged in parallel on the rod body of the inner rod, and a clamping groove is formed between two adjacent connecting plates;

[0022] At least one of the clamping parts is disposed at the mouth of the outer cylinder, the number of the clamping slots is consistent with that of the clamping parts and they correspond one to one, and the outer cylinder can be inserted into the corresponding clamping slot through the clamping part to clamp the inner rod.

[0023] By adopting the above technical solution, when the top end of the inner rod is close to the clamping piece at the barrel mouth, the clamping piece can be inserted into the clamping groove and clamped with the inner rod.

[0024] Specifically, it also includes a pressure plate, on one side of which a hinge shaft is eccentrically arranged. The bottom end of the inner rod is hinged on the hinge shaft on one side close to the lamp pole. When the lamp pole is perpendicular to the ground plane, the side of the pressure plate away from the hinge shaft is abutted between the inner rod and the lamp pole. When the lamp pole is tilted, the pressure plate can rotate around the hinge shaft and make the bottom end of the inner rod abut against the surface of the pressure plate.

[0025] By adopting the above technical solution, when the lamp pole is perpendicular to the ground plane, the side of the pressure plate away from the hinge axis is abutted between the inner rod and the lamp pole. When the lamp pole is tilted, due to the eccentric setting of the hinge axis on the pressure plate, the pressure plate will rotate around the hinge axis under the action of its own weight and make the bottom end of the inner rod abut against the surface of the pressure plate, so that the pressure plate can be cushioned between the inner rod and the ground, thereby reducing the pressure applied to the ground by the inner rod through the pressure plate, thereby avoiding the situation where the inner rod pierces the floor tiles.

[0026] Furthermore, the lamp pole is provided with a hanging rod, and the pressure plate is provided with a hanging hole. When the lamp pole is perpendicular to the ground plane, the hanging rod passes through the hanging hole and abuts against the top wall of the hanging hole.

[0027] By adopting the above technical solution, when the lamp pole is perpendicular to the ground plane, the pressure plate can be hung on the hanging rod through the hanging hole. When the lamp pole is inclined to the ground plane, the bottom end of the telescopic rod will rotate with the pressure plate away from the lamp pole, so that the pressure plate can automatically slide off the hanging rod.

[0028] Furthermore, a clamping protrusion is provided on the bottom end of the inner rod, and a clamping groove is provided on the disk surface on one side of the pressure plate close to the inner rod. When the lamp pole is tilted, the clamping protrusion can be inserted into the clamping groove.

[0029] By adopting the above technical solution, the clamping protrusion can cooperate with the clamping groove to share the pressure borne by the hinge between the pressure plate and the inner rod, so that the hinge between the pressure plate and the inner rod is not easily damaged.

[0030] The second aspect of the present application provides a method for installing an anti-dumping LED lighting street lamp. When the telescopic rod and the driving assembly are installed on the lamp pole, the following installation steps are adopted:

[0031] First, rotate the bent rod until the end of the bent rod away from the mounting protrusion is facing away from the telescopic rod, and then use a bonding device such as tape to fix the bent rod on the mounting protrusion, so that the valve core at the bottom end of the bent rod can cut off the airflow in the connecting hole, then connect the pressure supply part with the air receiving groove, and then insert the mounting protrusion into the mounting hole and hinge the mounting protrusion to the hole wall of the mounting hole, then adjust the rod body of the telescopic rod to a vertical state, and then rotate the bent rod until the end of the bent rod away from the mounting protrusion abuts against the top wall of the mounting hole, and finally remove the bonding device from the bent rod.

[0032] By adopting the above technical solution, since the interior of the lamp pole requires wiring and generally adopts a hollow setting, when installing the telescopic rod and the drive assembly on the lamp pole, the above installation steps allow the bent rod to first pass through the mounting hole and enter the interior of the lamp pole, so as to ensure that the bent rod will not collide with the hole wall of the mounting hole, thereby protecting the bent rod.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. It includes a lamp holder, a lamp pole, a lamp head, a telescopic rod and a driving assembly. The lamp holder is buried in the roadbed on one side of the road, the bottom end of the lamp pole is connected to the lamp holder, and the lamp head is arranged at the top end of the lamp pole; the telescopic rod includes an outer tube and an inner rod, the top end of the outer tube is hinged on the side of the lamp pole away from the road, the bottom end of the outer tube extends downward and is provided with a tube mouth, the top end of the inner rod passes through the tube mouth and is inserted into the outer tube and can slide along the inner wall of the outer tube, and a clamping piece is arranged at the tube mouth; the driving assembly is transmission-connected with the inner rod, and when the hinged part of the outer tube and the lamp pole tilts in the direction away from the road, the driving assembly can drive the top end of the inner rod to approach and clamp the clamping piece, and the bottom end of the inner rod abuts against the road surface, so that the lamp pole can be supported by the telescopic rod, so that the lamp pole is not easy to fall down before the maintenance personnel arrive, thereby protecting the buildings and pedestrians around the anti-dumping LED lighting street lamp;

[0035] 2. The control component includes a valve core and a bent rod. A receiving groove is provided on the hole wall of the connecting hole, and the valve core is arranged in the receiving groove. A connecting hole is provided on the top wall of the receiving groove. One end of the bent rod passes through the connecting hole and extends into the receiving groove and is connected to the valve core. The other end of the bent rod abuts against the top wall of the mounting hole. A crease is provided at the bending part of the bent rod. When the lamp pole is perpendicular to the ground plane, one end of the bent rod will abut against the top wall of the mounting hole, and the other end of the bent rod will abut the valve core against the hole wall of the connecting hole, so that the valve core keeps the state of cutting off the airflow in the connecting hole. When the lamp pole is tilted, since the top of the telescopic rod is hinged to the lamp pole, the bottom end of the telescopic rod will rotate in the direction away from the lamp pole under the action of its own weight, so that the end of the bent rod inserted into the connecting hole can move toward the direction close to the other end of the bent rod and break the bent rod from its own crease, so that the airflow in the connecting hole can push the valve core into the receiving groove, and then the airflow in the connecting hole can enter the outer cylinder.

[0045] Figure 3 yes Figure 2 Schematic enlargement of area A, showing the bent rod, Figure 4 yes Figure 2 Schematic enlargement of region B in FIG, showing the articulation axis. Figure 3 and Figure 4The side opening of the connecting hole 432 is arranged on the side wall of the gas receiving groove away from the groove, and the side opening of the connecting hole 432 is provided with a gas nozzle 431 adapted to the pressure supply member 51, so that the high-pressure gas in the high-pressure gas tank can enter the connecting hole 432 through the gas nozzle 431; the control member 52 includes a valve core 521 and an L-shaped bent rod 522, a receiving groove is arranged on the hole wall of the connecting hole 432, the valve core 521 is arranged in the receiving groove, a connecting hole is arranged on the top wall of the receiving groove, and the L-shaped bent rod 52 One end of the L-shaped bent rod 52 passes through the connecting hole and extends into the accommodating groove and is connected to the valve core 521, and the other end of the L-shaped bent rod 522 abuts against the top wall of the mounting hole. A fold 5221 is provided at the bending part of the L-shaped bent rod 522, and the L-shaped bent rod 522 can be a plastic rod or an easily broken metal rod; a hinge shaft 62 is eccentrically arranged on the disk surface of one side of the pressure plate 6, and the side of the bottom end of the inner rod 42 close to the lamp pole 2 is hinged on the hinge shaft 62, a hanging rod is provided on the lamp pole 2, and a hanging hole 61 is opened on the pressure plate 6.

[0046] With the above arrangement, when the lamp pole 2 is perpendicular to the ground plane, one end of the bent rod 522 will abut against the top wall of the mounting hole, and the other end of the bent rod 522 will abut the valve core 521 against the hole wall of the connecting hole 432, so that the valve core 521 keeps cutting off the airflow in the connecting hole 432, and the pressure plate 6 is hung on the hanging rod through the hanging hole 61, so that the telescopic rod 4 is in a retracted state; when an out-of-control vehicle on the road scrapes or collides with the side of the lamp pole 2 close to the road, the part of the lamp pole 2 above the collision point will tilt away from the road. Since the top of the telescopic rod 4 is hinged to the lamp pole 2, the bottom end of the telescopic rod 4 will rotate in the direction away from the lamp pole 2 under the action of its own weight, which can not only make the pressure plate 6 automatically slip off the hanging rod, but also make the end of the bent rod 522 inserted into the connecting hole 432 move toward the direction close to the other end of the bent rod 522 and break the bent rod 522 from its own crease 5221, thereby The airflow in the connecting hole 432 can push the valve core 521 into the receiving groove, and then the airflow in the connecting hole 432 can enter the outer tube 41, so as to drive the inner rod 42 to extend out of the outer tube 41 and make the top of the inner rod 42 engage with the clamping piece 411 at the tube mouth of the outer tube 41. Due to the eccentric setting of the hinge shaft 62 on the pressure plate 6, when the pressure plate 6 slides off the hanging rod, the pressure plate 6 will automatically rotate around the hinge shaft 62 under the action of its own weight and make the bottom end of the inner rod 42 abut against the disk surface of the pressure plate 6, so that the pressure plate 6 can be cushioned between the inner rod 42 and the ground, which can reduce the pressure applied to the ground by the inner rod 42 through the pressure plate 6 to avoid the situation that the inner rod 42 pierces the floor tiles on the ground, and can also support the lamp pole 2 through the cooperation of the pressure plate 6 and the telescopic rod 4, so that the lamp pole 2 is not easy to fall down before the maintenance personnel arrive, thereby protecting the buildings and pedestrians around the anti-dumping LED lighting street lamp.

[0047] Figure 5is along Figure 2 A schematic cross-sectional view taken along the CC direction, Figure 6 is along Figure 2 Schematic cross-sectional view taken along the DD direction. Figure 5 and Figure 6 , a plurality of connecting plates 422 are arranged in parallel on the rod body of the inner rod 42, and a clamping groove is formed between two adjacent connecting plates 422; a plurality of clamping members 411 are arranged at the tube mouth of the outer tube 41, and the number of the clamping grooves and the clamping members 411 are the same and correspond one to one, and the outer tube 41 can be inserted into the corresponding clamping groove through each clamping member 411 to clamp the inner rod 42. A hemispherical clamping protrusion 423 is arranged on the bottom end of the inner rod 42, and a clamping groove 63 is arranged on the side of the pressure plate 6 close to the inner rod 42. When the lamp pole 2 is tilted, the clamping protrusion 423 can be inserted into the clamping groove 63, so that the pressure on the hinge of the pressure plate 6 and the inner rod 42 can be shared through the clamping protrusion 423 and the clamping groove 63, so that the hinge of the pressure plate 6 and the inner rod 42 is not easily damaged.

[0048] Based on the structure of the above-mentioned anti-dumping LED lighting street lamp, the present application also provides an anti-dumping LED lighting street lamp installation method, which is implemented by using the above-mentioned anti-dumping LED lighting street lamp. When the telescopic rod 4 and the driving assembly 5 are installed on the lamp pole 2, the following installation steps are specifically adopted:

[0049] First, rotate the bent rod 522 until the end of the bent rod 522 away from the mounting protrusion 43 is facing away from the telescopic rod 4, and then use a bonding device such as tape to fix the bent rod 522 on the mounting protrusion 43, so that the valve core 521 at the bottom end of the bent rod 522 can cut off the airflow in the connecting hole 432, then connect the pressure supply part 51 with the air receiving groove, and then insert the mounting protrusion 43 into the mounting hole and hinge the mounting protrusion 43 to the hole wall of the mounting hole, then adjust the rod body of the telescopic rod 4 to a vertical state, and then rotate the bent rod 522 until the end of the bent rod 522 away from the mounting protrusion 43 abuts against the top wall of the mounting hole, and finally remove the bonding device from the bent rod 522.

[0050] Since the anti-dumping LED lighting street lamp installation method of the present application is implemented by adopting the above-mentioned anti-dumping LED lighting street lamp, it can also have all the technical effects of the above-mentioned anti-dumping LED lighting street lamp. In particular, since the interior of the lamp pole 2 requires wiring and generally adopts a hollow setting, when the telescopic rod 4 and the driving assembly 5 are installed on the lamp pole 2, the above-mentioned installation steps enable the bent rod 522 to first pass through the mounting hole and enter the interior of the lamp pole 2, so as to ensure that the bent rod 522 will not collide with the hole wall of the mounting hole, thereby protecting the bent rod 522.

[0051] Figure 7is a schematic cross-sectional view of the second embodiment of the present application taken along the central axis of the lamp pole, wherein only a portion of the lamp pole is shown. Figure 7 In the second embodiment provided by the present application, the control member 52 includes a tilt sensor 523, an electric control valve 524 and a controller. The tilt sensor 523 is arranged on the lamp pole 2. The tilt sensor 523 may be a tilt sensor, so that the tilt angle between the lamp pole 2 and the ground plane can be detected by the tilt sensor. The tilt sensor 523 is electrically connected to the controller and can feed back the tilt angle to the controller. The electric control valve 524 is arranged in the connecting hole 432. The controller is electrically connected to the electric control valve 524 and can control the opening and closing of the electric control valve 524 according to the tilt angle. Through the above arrangement, the tilt sensor 523 can detect the tilt angle between the lamp pole 2 and the ground plane. When the tilt angle is 90 degrees, the controller will control the electric control valve 524 to always remain in a closed state; when the tilt angle is not 90 degrees, the controller will control the electric control valve 524 to open, so that the airflow in the connecting hole 432 can enter the outer cylinder 41.

[0052] The implementation principle of an anti-dumping LED lighting street lamp described in this application is:

[0053] When the lamp pole 2 is perpendicular to the ground plane, one end of the bent rod 522 will abut against the top wall of the mounting hole, and the other end of the bent rod 522 will abut the valve core 521 against the hole wall of the connecting hole 432, so that the valve core 521 keeps cutting off the airflow in the connecting hole 432, and the pressure plate 6 is hung on the hanging rod through the hanging hole 61, so that the telescopic rod 4 is in a retracted state; when an out-of-control vehicle on the road scrapes or collides with the side of the lamp pole 2 close to the road, the part of the lamp pole 2 above the collision point will tilt away from the road. Since the top of the telescopic rod 4 is hinged to the lamp pole 2, the bottom end of the telescopic rod 4 will rotate in the direction away from the lamp pole 2 under the action of its own weight, which can not only make the pressure plate 6 automatically slip off the hanging rod, but also make the end of the bent rod 522 inserted into the connecting hole 432 move toward the direction close to the other end of the bent rod 522 and break the bent rod 522 from its own crease 5221, thereby making The airflow in the connecting hole 432 can push the valve core 521 into the receiving groove, and then the airflow in the connecting hole 432 can enter the outer tube 41, so as to drive the inner rod 42 to extend out of the outer tube 41 and make the top of the inner rod 42 snap into the clamping piece 411 at the tube mouth of the outer tube 41. Due to the eccentric setting of the hinge shaft 62 on the pressure plate 6, when the pressure plate 6 slides off the hanging rod, the pressure plate 6 will automatically rotate around the hinge shaft 62 under the action of its own weight and make the bottom end of the inner rod 42 abut against the disk surface of the pressure plate 6, so that the pressure plate 6 can be cushioned between the inner rod 42 and the ground, which can reduce the pressure applied to the ground by the inner rod 42 through the pressure plate 6 to avoid the situation that the inner rod 42 pierces the floor tiles on the ground, and can also support the lamp pole 2 through the cooperation of the pressure plate 6 and the telescopic rod 4, so that the lamp pole 2 is not easy to fall down before the maintenance personnel arrive, thereby protecting the buildings and pedestrians around the anti-dumping LED lighting street lamp.
