Description

Technical Field

[0001] The present application belongs to the technical field of explosion-proof lamps, and in particular, relates to an LED explosion-proof lamp. Background Art

[0002] LED explosion-proof lamps are a type of explosion-proof lamps. Their principles are the same as those of explosion-proof lamps, except that the light source is an LED light source. They refer to lamps that take various specific measures to prevent the ignition of surrounding explosive mixtures such as explosive gas environments, explosive dust environments, and gas.

[0003] The existing foreign patent with publication number KR102256367B1 discloses a dustproof and explosion-proof lamp, in which the LED lighting lamp is installed at the front center of the front surface of the area where the LED lamp is installed, and the transparent flexible window sheet is installed in the inner plate. The transparent flexible window sheet is partially wound on one of the two rollers and exposed to the outside, and the transparent flexible window sheet is partially wound on the other roller to expose the transparent flexible window sheet.

[0004] Although the above-mentioned LED lamps are dustproof and explosion-proof, due to the special working environment of explosion-proof lamps, for safety reasons, explosion-proof lamps need to be regularly disassembled for maintenance and repair. However, when the transparent flexible window is damaged, it may be difficult to quickly determine, and it is easy for the LED explosion-proof lamps to be unable to remove dust after long-term use, resulting in reduced lighting effects. Utility Model Content

[0005] The purpose of this application is to provide an LED explosion-proof lamp to address the above-mentioned technical problems, which can quickly detect and repair the damaged transparent flexible parts.

[0006] The present application provides an LED explosion-proof lamp, comprising:

[0007] Lamp housing;

[0008] LED lamp, the LED lamp comprising an LED lamp panel and a lampshade;

[0009] A transparent flexible part that abuts against the lampshade;

[0010] A cover shell, movably mounted on the lamp housing;

[0011] Rollers are respectively placed on both sides of the cover shell, and the transparent flexible member is wound around the rollers;

[0012] A driving device, mounted and connected with the roller;

[0013] A detection sensor is mounted on the housing and corresponds to the roller;

[0014] A locking assembly is placed between the cover and the lamp housing;

[0015] The first spring abuts against the cover.

[0016] The LED lamp is installed in the lamp housing for emitting light, and the LED lamp board is energized to emit light. The LED lamp board is sealed and protected by the lampshade, and the transparent flexible member is abutted against the outer side of the lampshade to prevent dust from accumulating on the lampshade. The transparent flexible member is controlled to move by a roller so that when dust accumulates on the transparent flexible member, the dust is moved away, so that the transparent flexible member corresponding to the lampshade maintains light transmittance, thereby ensuring that the brightness emitted by the LED lamp is stable. The roller is installed on the cover shell, and the transparent flexible member is wound around the roller. When the driving device corresponding to one of the rollers is wound and the other roller is unwound, the driving device corresponding to the unwinding roller is closed, and the unwinding roller pulls the transparent flexible member to rotate through the winding roller. When the transparent flexible member is broken or the winding driving device is damaged, the detection sensor corresponding to the winding roller detects that the roller has not rotated, and controls the locking assembly to release the locking of the lamp housing to the cover shell. The first spring acts on the cover shell, and when the LED explosion-proof lamp is inspected, it can be clearly observed that the cover shell extends out of the lamp housing.

[0017] Furthermore, the locking assembly comprises:

[0018] A first locking member is movably mounted on the inner wall of the lamp housing;

[0019] A second spring is disposed between the first locking member and the lamp housing;

[0020] A first electromagnet is mounted on the first locking member and the lamp housing respectively;

[0021] Wherein, the cover shell is provided with a locking portion corresponding to the first locking piece.

[0022] When the locking assembly releases the lock of the lamp housing on the cover shell, the first electromagnet is energized to generate an interaction force to control the first locking piece to move away from the locking portion, so that the first locking piece is separated from the locking portion; when the cover shell needs to be locked, the first electromagnet does not work, and the first locking piece is extended toward the locking portion under the action of the second spring, so as to facilitate the locking of the first locking piece with the locking portion.

[0023] Furthermore, the cover shell is provided with a first limiting portion, the lamp housing is provided with a second limiting portion corresponding to the first limiting portion, and the second limiting portion is movably mounted on the lamp housing.

[0024] When the locking assembly releases the lock of the lamp housing on the cover shell, the first spring acts on the cover shell to control the cover shell to move outside the lamp housing until the first limit part and the second limit part are against each other. At this time, half of the cover shell is placed outside the lamp housing, and the second limit part is movably installed on the lamp housing. By moving the second limit part, the first limit part and the second limit part are separated, and the cover shell continues to extend outward under the action of the first spring.

[0025] Furthermore, the cover shell is provided with a telescopic seat, the lamp housing is provided with a telescopic column, and the first spring is sleeved on the telescopic column and abuts against the telescopic seat.

[0026] The telescopic seat cooperates with the telescopic column to improve the stability of the cover shell when moving. The first spring is sleeved on the telescopic column and abuts against the telescopic seat, so that the elastic force of the first spring acts on the cover shell and the installation stability of the first spring is guaranteed.

[0027] Furthermore, the cover shell is provided with a brush portion, and the brush portion abuts against the transparent flexible member.

[0028] When the transparent flexible member moves, the dust on the surface of the transparent flexible member is brushed off by the installed brush part, so that the transparent flexible member can be recycled.

[0029] Furthermore, the housing comprises:

[0030] A cover body, hinged on the cover shell;

[0031] A second locking member is movably mounted on the cover;

[0032] a third spring, disposed between the second locking member and the housing;

[0033] A second electromagnet is disposed between the second locking member and the cover;

[0034] A third locking member is movably mounted on the cover, and the third locking member is provided with a handle;

[0035] a fourth spring, disposed on the third locking member and the cover;

[0036] Wherein, the cover body is provided with a first locking groove corresponding to the second locking member, and the second locking member is provided with a second locking groove corresponding to the third locking member.

[0037] When the driving device is damaged, the detection sensor detects that the two rollers rotate evenly. At this time, the locking assembly is unlocked, and the cover body and the cover shell are still locked. When the driving device works normally but the transparent flexible member is broken, one of the two rollers rotates and the other does not rotate. The second electromagnet controls the second locking member to move, so that the second locking member is separated from the first locking groove, and the lock between the cover body and the cover shell is released. At the same time, the second locking member cooperates with the second locking groove through the third locking member to keep the second locking member in a retracted state. When the cover shell moves out of the lamp shell, the first limiting portion and the second limiting portion are passed through the first limiting portion, so that the cover body is restricted and cannot be opened. When the first limiting portion and the second limiting portion are separated and the cover shell continues to extend out of the lamp shell, the cover body is opened, which is convenient for replacing the transparent flexible member. When the cover body is locked again, the third locking member is separated from the second locking groove by moving the handle, so that the second locking member is reset under the action of the third spring, and then the third locking member is reset under the action of the fourth spring.

[0038] The beneficial effects of this application are:

[0039] 1. The transparent flexible part is pressed against the outer side of the lampshade to prevent dust from accumulating on the lampshade. The roller controls the movement of the transparent flexible part so that when dust accumulates on the transparent flexible part, the dust is removed by moving the transparent flexible part. This allows the transparent flexible part corresponding to the lampshade to maintain light transmittance and ensure the stability of the brightness emitted by the LED lamp.

[0040] 2. When the transparent flexible part breaks or the winding drive device is damaged, the detection sensor corresponding to the winding roller detects that the roller is not rotating, and controls the locking assembly to release the lock of the lamp housing on the cover shell. The first spring acts on the cover shell. When checking the LED explosion-proof lamp, it can be clearly observed that the cover shell extends out of the lamp housing.

[0041] 3. When the locking assembly releases the lock of the lamp housing on the cover shell, the first spring acts on the cover shell to control the cover shell to move outside the lamp housing until the first limit part and the second limit part are against each other. At this time, half of the cover shell is placed outside the lamp housing, and the second limit part is movably installed on the lamp housing. By moving the second limit part, the first limit part and the second limit part are separated, and the cover shell continues to extend outward under the action of the first spring.
