A maintenance-free LED explosion-proof light

Abstract

This utility model discloses a maintenance-free LED explosion-proof lamp, relating to the field of LED explosion-proof lamp technology. The utility model includes: a lamp body and a mounting plate disposed on the upper end of the lamp body; two fixed frames, symmetrically distributed and fixedly installed on the bottom of the mounting plate, with lifting plates slidably inserted into each of the two fixed frames, and a rotating plate rotatably installed between the two lifting plates. This utility model uses an electric lifting assembly to drive the two lifting plates to rise or fall synchronously within the vertical sliding grooves of the fixed frames, achieving stepless adjustment of the lamp body height. When it is necessary to change the illumination direction, the drive motor drives the rotating shaft to rotate, and the rotating plate rotates accordingly, thereby causing the lamp body at its bottom to rotate at an angle. The entire lifting process does not require manual climbing; it only requires ground remote control or on-site button operation. Simultaneously, after rotating to the specified angle, the positioning assembly locks the lamp body's angle, eliminating the loosening hazards caused by traditional manual angle rotation and bolt tightening.

Description

Technical Field

[0001] This utility model relates to the field of LED explosion-proof light technology, specifically to a maintenance-free LED explosion-proof light. Background Technology

[0002] Explosion-proof lights are essential lighting fixtures in current safe production. In places containing flammable and explosive gases or dust, explosion-proof work is of paramount importance. Ordinary lighting fixtures inevitably generate electric sparks or form high-temperature surfaces during operation, which are significant safety hazards. Explosion-proof lights mainly reduce safety hazards by suppressing the generation of electric sparks or increasing heat dissipation efficiency. Traditional explosion-proof lights have also been continuously improved, evolving into the commonly seen maintenance-free LED explosion-proof lights. These maintenance-free LED explosion-proof lights have the characteristics of long lifespan, low maintenance costs, greater energy efficiency, and enhanced safety.

[0003] Existing maintenance-free LED explosion-proof lights typically achieve height and illumination angle adjustment through telescopic brackets or universal joint structures. However, such products still have significant shortcomings in actual use: on the one hand, height and angle adjustments mostly rely on manual operation, requiring operators to climb to heights to repeatedly tighten and loosen bolts and operate clips, a tedious and time-consuming process. On the other hand, frequent manual adjustments not only increase the labor intensity of workers but also pose safety hazards such as uneven force leading to component wear, loose positioning, or even the light fixture falling. Utility Model Content

[0004] The purpose of this utility model is to provide a maintenance-free LED explosion-proof light in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model employs the following technical solution: a maintenance-free LED explosion-proof light, comprising: a light body and a mounting plate disposed on the upper end of the light body; two fixing frames, symmetrically distributed and fixedly installed on the bottom of the mounting plate, each fixing frame having a lifting plate slidably inserted thereon, a rotating plate rotatably installed between the two lifting plates, the light body being fixedly installed on the bottom of the rotating plate, and a drive motor for rotating the rotating plate being fixedly installed on one side of one of the lifting plates; a positioning component, mounted on the lifting plate, for positioning and fixing the rotation angle of the rotating plate; and an electric lifting component, mounted on the mounting plate, for raising and lowering the two lifting plates.

[0006] Furthermore, the positioning component includes two arc-shaped plates respectively fixedly installed on both sides of the top of the lamp body. Multiple insertion holes are fixedly installed on both arc-shaped plates in an array. Electric push rods are fixedly installed at the bottom ends of both lifting plates. Insert rods are fixedly installed at the telescopic ends of both electric push rods, and the insert rods are inserted into one of the insertion holes.

[0007] Furthermore, the electric lifting assembly includes two electric telescopic rods fixedly installed at the bottom of the mounting plate, a connecting plate fixedly installed between the two lifting plates, and the telescopic ends of the two electric telescopic rods fixedly connected to the top of the connecting plate.

[0008] Furthermore, multiple heat dissipation fins are fixedly installed on the top of the lamp body, and two cooling fans are fixedly inserted into the top of the lamp body.

[0009] Furthermore, the heat dissipation fins are S-shaped and have multiple openings.

[0010] Furthermore, a fixing plate is installed on the top of the mounting plate, and the fixing plate is fixed to the wall by bolts. A first semicircular plate is fixedly installed on both sides of the mounting plate, and two second semicircular plates are fixedly installed on both sides of the fixing plate. A connecting sleeve is threaded between each of the first semicircular plates and the second semicircular plates.

[0011] Furthermore, a positioning frame is fixedly installed on the lamp body, and sliders are slidably installed on both sides of the positioning frame. Wiping cotton plates are rotatably installed on the two sliders through a damping shaft.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model uses an electric lifting assembly to drive the lifting plates on both sides to rise or fall synchronously within the vertical slide groove of the fixed frame, achieving stepless adjustment of the lamp body height. When it is necessary to change the illumination direction, the drive motor drives the rotating shaft to rotate, and the rotating plate rotates accordingly, thereby causing the lamp body at its bottom to rotate at an angle. The entire lifting process does not require manual climbing; it only requires ground remote control or on-site button operation. At the same time, after rotating to the specified angle, the positioning assembly locks the angle of the lamp body, eliminating the risk of loosening caused by traditional manual angle rotation and bolt tightening.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figure 1-4 As shown, an embodiment of the present invention provides a maintenance-free LED explosion-proof lamp, comprising: a lamp body 1 and a mounting plate 2 disposed on the upper end of the lamp body 1;

[0021] There are two fixed frames 21, which are symmetrically distributed and fixedly installed on the bottom of the mounting plate 2. Each of the two fixed frames 21 is slidably inserted with a lifting plate 3. A rotating plate 4 is rotatably installed between the two lifting plates 3. The lamp body 1 is fixedly installed on the bottom of the rotating plate 4. A drive motor 41 for driving the rotating plate 4 to rotate is fixedly installed on one side of one of the lifting plates 3.

[0022] Positioning component 5, which is installed on the lifting plate 3, is used to position and fix the rotation angle of the rotating plate 4.

[0023] An electric lifting assembly 6 is installed on the mounting plate 2 and is used to drive the two lifting plates to raise and lower their height.

[0024] The working principle of this maintenance-free LED explosion-proof light is as follows: the mounting plate 2 is rigidly connected to the wall or other designated positions in advance, and two symmetrical fixed frames 21 are suspended downwards. After the electric lifting component 6 is started, it drives the lifting plates 3 on both sides to rise or fall synchronously in the vertical slide groove of the fixed frame 21, realizing stepless adjustment of the height of the lamp body 1. The entire lifting process does not require manual climbing, but only requires ground remote control or local button operation. The lamp body 1 is fixed to the bottom surface of the rotating plate 4. The two ends of the rotating plate 4 are hinged between the two lifting plates 3 via the rotating shaft. When it is necessary to change the illumination direction, the drive motor 41 drives the rotating shaft to rotate, and the rotating plate 4 rotates accordingly, thereby driving the lamp body 1 at its bottom to rotate at an angle. When it rotates to the specified angle, the positioning component 5 locks the angle of the lamp body 1, eliminating the loosening hazard caused by traditional manual rotation angle and bolt tightening.

[0025] like Figure 2 As shown, in some embodiments, the positioning component 5 includes two arc-shaped plates 51 respectively fixedly installed on both sides of the top of the lamp body 1. Multiple insertion holes are fixedly installed on both arc-shaped plates 51 in an array. Electric push rods 52 are fixedly installed at the bottom ends of both lifting plates 3. Insert rods 53 are fixedly installed at the telescopic ends of both electric push rods 52. The insert rods 53 are inserted into one of the insertion holes.

[0026] An arc-shaped plate 51 is fixedly installed on each of the two sides of the top of the lamp body 1. The arc-shaped plate 51 has an array of evenly distributed insertion holes. The electric push rod 52 fixed at the bottom of the lifting plate 3 extends out to drive the insertion rod 53 to insert into the corresponding insertion hole to achieve instant locking, thereby eliminating the loosening risk caused by traditional manual bolt locking or buckle connection.

[0027] like Figure 2 As shown, in some embodiments, the electric lifting assembly 6 includes two electric telescopic rods 61 fixedly installed at the bottom of the mounting plate 2, a connecting plate 62 fixedly installed between the two lifting plates 3, and the telescopic ends of the two electric telescopic rods 61 are fixedly connected to the top of the connecting plate 62.

[0028] After the electric lifting assembly 6 is started, the two electric telescopic rods 61 extend and retract synchronously. Their telescopic ends are directly pushed and pulled to the connecting plate 62 between the two lifting plates 3, thereby driving the two lifting plates 3 to rise and fall steplessly along the vertical slide groove of the fixed frame 21, realizing precise adjustment of the height of the lamp body 1. After reaching the set position, it is immediately maintained by the internal self-locking or electromagnetic braking of the electric telescopic rod 61. There is no need for manual climbing, only ground remote control or local button operation.

[0029] like Figure 3 As shown, in some embodiments, a plurality of heat dissipation fins 7 are fixedly installed on the top of the lamp body 1, and two cooling fans 8 are fixedly inserted into the top of the lamp body 1. The heat dissipation fins 7 are S-shaped and have a plurality of openings.

[0030] The top of the lamp body 1 has densely fixed S-shaped heat dissipation fins 7, which increase the surface area and allow for full contact with the air. The multiple regularly distributed openings on the heat dissipation fins 7 further increase the air contact and improve the heat dissipation effect. Two cooling fans 8 are embedded in the top of the lamp body 1. After the cooling fans 8 are started, they generate airflow to quickly remove the heat generated by the lamp body 1, ensuring that the lamp body 1 maintains a safe temperature rise even under high power and long-term operation, and further extending the maintenance-free life.

[0031] like Figure 2 As shown, in some embodiments, a fixing plate 9 is installed on the top of the mounting plate 2, the fixing plate 9 is fixed to the wall by bolts, a first semicircular plate 10 is fixedly installed on both sides of the mounting plate 2, and two second semicircular plates 11 are fixedly installed on both sides of the fixing plate 9, and a connecting sleeve 12 is threaded between a single first semicircular plate 10 and a second semicircular plate 11.

[0032] The mounting plate 2 is pre-stacked with the fixing plate 9. The fixing plate 9 is rigidly connected to the wall surface by bolts. The first semi-circular plate 10 fixed on both sides of the mounting plate 2 and the two second semi-circular plates 11 extending outward on both sides of the fixing plate 9 form a coaxial annular mating surface. The connecting sleeve 12 is screwed into the internal thread of the coaxial annular surface from the outside, thereby quickly suspending the mounting plate 2 and all the components below it on the fixing plate 9, which facilitates quick installation and disassembly.

[0033] like Figure 4 As shown, in some embodiments, a positioning frame 13 is fixedly installed on the lamp body 1, and sliders 14 are slidably installed on both sides of the positioning frame 13. The two sliders 14 are rotatably mounted with wiping cotton plates 15 through a damping shaft.

[0034] When it is necessary to clean the accumulated dust on the surface of the lamp body 1, the electric lifting component 6 is used to move the lamp body 1 down to a lower height. Then, the wiping cotton plate 15 is manually rotated to be vertical, and then the wiping cotton plate 15 is pushed. Under the action of the slider 14, the wiping cotton plate 15 wipes the surface of the lamp body 1.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
