Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamp poles, in particular to an energy-saving lamp pole with adjustable inclination angle. BACKGROUND

[0002] A lamp pole is a vertical structural pole used to support and fix street light fixtures in a road lighting system. It usually has a channel inside for laying and protecting power lines or traction ropes. Its height is determined according to road grade, lighting requirements, and installation environment, typically between 6-15 meters. The top of the lamp pole is provided with a fixture mounting interface, and the bottom is connected to the foundation through direct burial or by setting a base.

[0003] A lifting lamp pole is an intelligent lighting device developed from the traditional lamp pole. Its core feature is that the fixture part can move up and down inside the lamp pole through a mechanical lifting system. The working principle of the lifting lamp pole is that the cylinder or lifting platform carrying the fixture is driven by the built-in lifting mechanism (usually including a motor, a speed reducer, a steel wire rope or chain transmission system, a guide device, etc.) to move vertically along the guide rail inside the lamp pole. The operator can use the ground control system to lower the fixture to a convenient height for maintenance, such as cleaning, replacing light bulbs, repairing photovoltaic panels or circuits, etc. After completing the maintenance work, the fixture is raised to the normal working height.

[0004] Chinese patent document (publication number: CN118729180B) discloses a wind-solar storage complementary lifting lamp pole, which includes a foundation, a lamp pole mounted on the foundation, a bracket mounted on the lamp pole, a fixture, a lifting mechanism, and a storage mechanism. The lifting mechanism includes a box, a wire arrangement structure, a lifting rod, a resolving mechanism, and an identification mechanism. The wire arrangement structure is used to pull the lifting rod, the bottom end of the lifting rod is fixedly connected with the fixture, the box is provided with a cavity inside and a lifting opening at the bottom for the sliding adaptation of the lifting rod. An adjusting mechanism is further provided between the box and the lifting rod. This application uses photovoltaic panels and fans for photovoltaic power generation and wind power generation, which meets the requirements of green environmental protection. In addition, it also has the effect of automatically melting frozen rain to ensure the normal operation of the fixture lifting work.

[0005] The existing lamp pole adjusts the up-down position of the support pole by using a lifting mechanism. When the lifting mechanism fails or is subjected to external impact, the cylinder connected to the support pole is prone to rapid descent or even dangerous falling. The traditional safety protection measures cannot provide effective multiple protection, especially after the cylinder suddenly stops, the support pole will be impacted due to inertia, which is prone to structural damage at the structural connection part.

[0017] Compared with the prior art, the present application has the following beneficial effects: 1、The present application has perfect safety protection mechanism: when the barrel body rapidly drops due to failure, the system will automatically start multiple safety protection measures; first, the swing rod assembly immediately responds and prevents the barrel body from continuing to drop; at the same time, the push rod fixing assembly and the buffer assembly are triggered to work cooperatively; among them, the push rod fixing assembly implements deceleration and energy dissipation processing on the lamp pole through the encircling friction contact; the buffer assembly converts the connection mode between the support rod and the lamp pole from rigid connection to flexible connection, and timely dissipates energy; this series of linkage protection measures effectively prevent the stress concentration phenomenon of the street lamp support rod and the photovoltaic panel support rod after rapid movement and sudden stop, thereby reducing the probability of structure fracture or damage.

[0019] 3、In the present application, the push rod fixing assembly triggers the multi-point friction clamping mechanism to realize the continuous dissipation and deceleration control of the residual drop kinetic energy of the barrel body, provides auxiliary continuous friction braking for the instantaneous locking braking of the swing rod assembly, effectively prevents the impact vibration and structural stress of the barrel body due to residual kinetic energy in the locked state, and ensures the stability and safety of the emergency braking process; Specifically, when the swing lever assembly triggers, the slider moves down to drive the wedge block to move down synchronously, the inclined surface of the wedge block abuts against the inner wall of the second traction groove, the vertical downward force of the wedge block acts on the inclined surface to drive the guide ring to rotate around the central axis, the wave troughs evenly distributed on the inner circumference of the guide ring sequentially contact the ends of the push rods at corresponding positions during the rotation, the convex surface of the wave troughs applies a radial pushing force to the push rods to make them move inward toward the center of the lamp pole against the pre-tightening elastic resistance of the convex disc spring, the push rods convert the axial movement into the synchronous inward movement of the friction rods through the constraint of the T-shaped guide groove, a plurality of friction rods simultaneously shrink inward under the drive of the push rods until they form a uniform and close contact with the outer circumferential surface of the lamp pole, the contact pressure between the friction rods and the outer surface of the lamp pole generates a frictional resistance, the direction of the frictional force is opposite to the direction of the downward movement of the cylinder to form a braking force, and the downward kinetic energy of the cylinder is converted into friction heat energy through friction work and dissipated.

[0020] 4、In the present application, the buffer assembly effectively absorbs and dissipates the impact kinetic energy generated by the inertia movement of the support pole through the dual mechanism of connection mode conversion and elastic energy storage and friction energy dissipation, provides flexible buffer protection for the inertia movement of the support pole after emergency stop, and prevents stress concentration effect and structural damage at the structural connection part due to the inertia impact of the support pole when the cylinder is suddenly stopped; Specifically, when the push rod fixed assembly works, the rotational movement of the guide ring drives the push plate to produce a circumferential advancing movement, the push plate pushes the thrust plate and the lifting block to move in the guide direction, the horizontal thrust of the lifting block is converted into a vertical upward lifting force acting on the lifting column through the wedge-shaped inclined surface, the lifting column moves upward along the axial direction under the action of the lifting force and drives the lock tongue fixed at the end to move upward synchronously, the lock tongue is separated from the surface of the lock plate to release the mechanical constraint on the connecting head, the connecting head immediately obtains the rotational freedom around the pivot to convert the connection mode between the street lamp support pole and the photovoltaic panel support pole and the cylinder from rigid fixation to flexible hinging, when the support pole system continues to maintain the downward movement trend after the cylinder is locked and braked due to the weight and downward inertia, the support pole system rotates around the pivot as the rotation center, the rotational movement of the support pole is transmitted to the connecting mechanism in the damping unit through the connecting head to make the two sleeves move axially relative to each other, the relative movement of the sleeves applies a compression load to the internal damping spring to make it elastically compress and deform, the damping spring converts the mechanical movement energy of the support pole system into elastic potential energy for temporary storage during the compression process, and the internal friction damping characteristics of the spring material and the mechanical friction generated by the relative movement of the sleeves convert part of the mechanical energy into heat energy to dissipate to the environment.

[0037] The rotational movement of the support rod is transmitted to the connecting mechanism in the damping unit 53 through the connecting head 45, causing the two sleeves 65 to move axially relative to each other, and the relative movement of the sleeves 65 exerts a compression load on the internal damping spring 67, causing it to elastically compress and deform. The damping spring 67 converts the mechanical kinetic energy of the support rod system into elastic potential energy during compression and temporarily stores it.

Through the dual mechanisms of elastic energy storage and frictional energy dissipation, the impact kinetic energy generated by the inertial movement of the support rod is effectively absorbed and dissipated. The three components form a complete safety protection control system through a multi-stage progressive mechanical linkage of inertia locking, push rod friction braking, and buffer elastic energy absorption, achieving full-process energy management and impact protection from instantaneous rigid braking to continuous friction deceleration to flexible buffer energy absorption.
