Description

Technical Field

[0001] This utility model relates to the field of LED floodlight technology, specifically to an LED floodlight for high-mast lighting with good wind resistance. Background Technology

[0002] As is well known, high-mast LED floodlights with good wind resistance are lighting devices specifically designed for outdoor high-mast lighting scenarios. They are typically installed on the top of high masts ranging from 15 to 50 meters in height and used for lighting large areas such as squares, airports, and stadiums. To improve wind resistance, steel wire ropes are usually installed around the light pole. One end of the steel wire rope is fixed to the middle part of the light pole, and the other end is fixed to the base. The steel wire ropes provide auxiliary support to the light pole, improving its stability and thus enhancing its wind resistance.

[0003] However, existing wind-resistant high-mast LED floodlights suffer from the problem of inconvenient steel wire rope adjustment: after long-term use, the steel wire rope is prone to slack due to material creep and wind vibration, and the traditional fixing structure cannot be easily tightened, causing the steel wire rope to fail in its taut state. This slack will reduce the support of the light pole, and may cause the light body to sway under strong wind loads. Tests have shown that the wind resistance stability in the slack state is reduced by about 30% compared to the initial state, which seriously affects the safety of the equipment in harsh environments such as typhoons. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an LED floodlight for high-mast lighting with good wind resistance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-mast LED floodlight with good wind resistance, comprising a base, a pre-embedded block, a connecting column, a body, a first limiting block, a second limiting block, and an auxiliary mechanism. The pre-embedded block is disposed at the bottom of the base, the connecting column is fixedly connected to the top of the base, the body is disposed at the top of the connecting column, the first limiting block and the second limiting block are sleeved on the outer wall of the connecting column, and the auxiliary mechanism includes an arc-shaped block, a first bolt, a groove, a square block, an electromagnet, a second bolt, a steel wire rope, a hook, and a frame. The arc-shaped block is connected to the connecting column. The outer wall of the connecting column is in contact with the arc-shaped block, which is located between the first limiting block and the second limiting block. The arc-shaped block is connected to the first limiting block and the second limiting block by the first bolt. The groove is formed on the base. One end of the electromagnet is connected to the outer wall of the block, and the other end of the electromagnet is attracted to the inner wall of the groove. The second bolt is threaded to connect the block and the inner wall of the groove. The frame is fixedly connected to the top of the block. One end of the wire rope is connected to the arc-shaped block, and the other end of the wire rope is connected to one end of the hook. The hook is hung on the frame. The auxiliary mechanism is provided in two sets.

[0008] To improve stability, this utility model is improved by symmetrically arranging the two sets of auxiliary mechanisms.

[0009] To improve stability, this utility model is improved by providing a plurality of first bolts, which are arranged symmetrically.

[0010] To improve stability, this utility model is improved by providing two second bolts, which are arranged symmetrically.

[0011] To improve the strength of the base, this utility model is improved by using alloy steel as the base material.

[0012] To improve the connection effect, the present invention is improved by welding the pre-embedded block to the base.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an LED floodlight for high-mast lighting with good wind resistance, and has the following beneficial effects:

[0015] This high-mast LED floodlight with excellent wind resistance features an auxiliary mechanism that allows for tension adjustment and quick replacement of the wire rope. When the wire rope becomes slack due to long-term use, the electromagnet can be turned off by controlling the button on the control block, the second bolt can be unscrewed, and the block can be pressed inward to tighten the wire rope to a taut state. The adjustment is then completed by the electromagnet attracting and fixing the bolt. If the auxiliary mechanism needs to be replaced, simply remove the bolt and separate the block and the arc block to disassemble the old mechanism and replace it with the new component. This design ensures that the wire rope is always kept taut, preventing a decrease in wind resistance stability due to slack. At the same time, the modular structure facilitates maintenance and replacement, improving the long-term reliability of the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4A high-mast LED floodlight with good wind resistance includes a base 1, a pre-embedded block 2, a connecting column 3, a body 4, a first limiting block 5, a second limiting block 6, and an auxiliary mechanism 7. The pre-embedded block 2 is disposed at the bottom of the base 1, the connecting column 3 is fixedly connected to the top of the base 1, the body 4 is disposed at the top of the connecting column 3, the first limiting block 5 and the second limiting block 6 are sleeved on the outer wall of the connecting column 3, and the auxiliary mechanism 7 includes an arc-shaped block 8, a first bolt 9, a groove 10, a square block 11, an electromagnet 12, a second bolt 13, a wire rope 14, a hook 15, and a frame 16. The arc-shaped block 8 contacts the outer wall of the connecting column 3. Located between the first limiting block 5 and the second limiting block 6, the arc-shaped block 8 is connected to the first limiting block 5 and the second limiting block 6 by the first bolt 9. The groove 10 is formed on the base 1. One end of the electromagnet 12 is connected to the outer wall of the block 11, and the other end of the electromagnet 12 is attracted to the inner wall of the groove 10. The second bolt 13 is threaded to connect the block 11 and the inner wall of the groove 10. The frame 16 is fixedly connected to the top of the block 11. One end of the wire rope 14 is connected to the arc-shaped block 8, and the other end of the wire rope 14 is connected to one end of the hook 15. The hook 15 is hung on the frame 16. The auxiliary mechanism 7 is provided in two sets.

[0023] Working principle: First, the pre-embedded block 2 is buried in the underground soil. Then, the base 1 is fixed to the designated position on the ground using mounting bolts (bolt specifications are M16×100mm, pre-embedded depth ≥500mm). Next, the equipment is connected to AC220V external mains power, and the power supply connection is completed through the waterproof junction box inside the base 1 (protection level IP65). Figure 1 As shown, at this time, the steel wire rope 14 in the auxiliary mechanism 7 is in a taut state. One end of it is fixed to the arc block 8 by a U-shaped clamp (tightening torque 8-10 N·m), and the other end is suspended from the frame 16 by a hook 15, forming a 45° diagonal support for the connecting column 3. It has been tested and can withstand a 500N lateral wind load. The main body 4 adopts a commercially available 100W LED floodlight (beam angle 120°, luminous efficacy ≥100lm / W). Its specific structure will not be described in detail here.

[0024] When the steel wire rope 14 becomes loose due to long-term use, adjust it according to the following steps: First, press the control button on the surface of the block 11 to turn off the electromagnet 12 (rated suction force 500N, working voltage DC24V), so that it stops adsorbing the groove 10 (the inner wall of the groove is plated with a 50μm thick martensitic stainless steel layer, and the surface roughness Ra≤1.6μm to enhance the adsorption force); then use a Phillips screwdriver to unscrew the two symmetrically arranged second bolts 13 (specification M8×25mm, material grade 8.8), press the block 11 to make it move inward 15-20mm along the guide groove (depth 10mm) on the inner wall of the groove 10, causing the steel wire rope 14 to tighten and straighten; then restart the electromagnet 12 to adsorb the inner wall of the groove, and use a screwdriver to screw the second bolts 13 into the preset M10 thread groove at the bottom of the groove (tightening torque 12-15N·m) to complete the fixation.

[0025] If the auxiliary mechanism 7 needs to be replaced, the operation is as follows: turn off the electromagnet 12 and remove the second bolt 13, lift the square block 11 upward to separate it from the groove 10; then use a wrench to unscrew the four evenly distributed first bolts 9 (specification M10×30mm) to disengage the arc block 8 from the first limit block 5 and the second limit block 6 (fitting gap ≤0.5mm), and the auxiliary mechanism 7 can be completely disassembled and replaced with the pre-assembled new parts provided by the manufacturer (including the arc block 8, wire rope 14 and frame 16 assembly);

[0026] A tension sensor (range 0-2000N, accuracy ±1%) is installed at the connection between the wire rope 14 and the hook 15. An LED display screen is embedded on the side of the base 1, which can display the wire rope tension value in real time during adjustment. The frame 16 adopts a U-shaped groove structure. After the hook 15 is inserted, a hook-and-loop connection is formed. The pull-out force is tested to be ≥800N, ensuring reliable transmission of wire rope tension. A sealing ring is provided between the electromagnet 12 and the groove 10. With the help of a waterproof electromagnet, rainwater can be prevented from seeping into the groove. Loctite243 thread-locking adhesive is applied to the threads of the first bolt 9 and the second bolt 13 to effectively prevent the bolts from loosening.

[0027] To improve stability, in this embodiment, two sets of auxiliary mechanisms 7 are symmetrically arranged along the central axis of the connecting column 3. The steel wire rope 14 of each set of auxiliary mechanisms 7 has an angle of 45° with the connecting column 3, and the preload of the steel wire rope 14 on both sides is consistent (800-1000N). The symmetrical inclined structure converts the lateral force generated by the wind load into the axial tension of the steel wire rope 14. Mechanical testing shows that the maximum displacement of the connecting column 3 under a level 12 typhoon can be reduced by 60%, ensuring that the lamp body remains balanced and stable in a strong wind environment.

[0028] To improve connection stability, in this embodiment, several first bolts 9 are symmetrically distributed between the arc-shaped block 8 and the first limiting block 5 and the second limiting block 6. The bolts are made of M10×30mm grade 8.8 high-strength steel, and a tightening torque of 12-15 N·m is applied evenly to make the arc-shaped block 8 fit tightly against the outer wall of the connecting column 3. This symmetrical bolt structure has been verified by vibration test, which can reduce stress concentration at the connection part and ensure that the lateral force of the wire rope 14 when tensioned can be evenly transmitted to the connecting column 3, thereby improving the stability of the overall structure.

[0029] To improve connection stability, this embodiment sets two second bolts 13 symmetrically distributed between the block 11 and the groove 10. The bolts are made of M8×25mm grade 8.8 high-strength steel and are screwed into the pre-set threaded groove at the bottom of the groove 10 from the threaded holes on both sides of the block 11. Each bolt is tightened with a torque of 12-15 N·m. The symmetrical layout makes the connection force between the block 11 and the groove 10 evenly distributed. Wind resistance test verification shows that it can effectively prevent the block 11 from shifting under the tension of the wire rope 14, ensure the stable transmission of the diagonal support force of the auxiliary mechanism 7 to the connecting column 3, and improve the structural reliability of the equipment in strong wind environment.

[0030] To improve the strength of the base 1, in this embodiment, the base 1 is made of alloy steel (grade Q355B), with a yield strength ≥355MPa and a tensile strength of 510-630MPa, which is 40% stronger than traditional carbon steel. The base 1 is hot-forged and then annealed to eliminate internal stress. The surface is then hot-dip galvanized (zinc layer thickness ≥85μm) combined with fluorocarbon spraying (film thickness ≥30μm), which combines high strength and salt spray corrosion resistance. It can withstand vertical loads of more than 10kN and lateral wind loads of 5kN, ensuring that the high mast light is stably installed in strong wind environments.

[0031] To improve the connection effect, in this embodiment, the embedded block 2 and the base 1 are connected by a full welding process. Before welding, the contact surfaces of the embedded block 2 and the base 1 are derusted and ground (roughness Ra≤6.3μm). CO2 gas shielded welding (welding wire grade ER50-6, diameter 1.2mm) is used, with a welding current of 180-220A and an arc voltage of 22-24V to form a continuous closed weld (weld leg height≥8mm). After welding, non-destructive testing (UT testing grade B) is performed to ensure that the welding strength is ≥90% of the strength of the base material of the base 1 and can withstand a pull-out force of more than 15kN, so that the base 1 and the underground foundation form a rigid whole and effectively resist the overturning moment caused by strong winds.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
