Description

Technical Field

[0001] The invention belongs to the technical field of explosion-proof lamps, in particular to an explosion-proof lamp for lighting in a chemical workshop. Background Art

[0002] Explosion-proof lamps 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 gaseous gases; explosion-proof lamps are suitable for special processing and manufacturing industries such as petrochemicals, chemicals, and pharmaceuticals, as well as more special warehouses, workshops, and other indoor and outdoor places that require floodlighting.

[0003] In the prior art, the light-transmitting plates of explosion-proof lamps used in chemical workshops are generally made of non-glass materials, which have a certain degree of adhesion when broken, and can avoid splashing injuries caused by the breakage of the light-transmitting plates. However, there are the following problems: First, in order to avoid the explosion-proof of the lighting lamp body plate, the light-transmitting plates are relatively thick. However, because there are corrosive gases or liquids in the chemical workshop, and because the explosion-proof lamps are installed at high places, the surface of the light-transmitting plates is not wiped and cleaned for a long time. These corrosive gases or liquids are easy to cause the surface of the light-transmitting plates to be uneven, affecting the light transmission effect of the lamp body and causing shadow spots; second, the existing cleaning is generally just manual wiping, but for a large number of lighting lamp bodies located at high places, manual wiping is inconvenient.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 13As shown, an explosion-proof lamp for lighting a chemical workshop according to an embodiment of the present invention comprises an annular shell 1; a light-transmitting plate 12 is fixedly connected to the bottom end of the annular shell 1; an upper cover plate 15 is connected to the top end of the annular shell 1 by bolts; a group of heat sinks 11 are fixedly connected to the outer wall of the annular shell 1; a lighting module 13 is fixedly connected to the annular shell 1, and the lighting module 13 is arranged in an annular shape, and a group of lamp body plates 14 are arranged on the lighting module 13, and a group of lamp body plates 14 are arranged in an annular shape; an annular tube 17 is fixedly connected to the top end of the light-transmitting plate 12, and the top end of the annular tube 17 is fitted to the bottom end of the upper cover plate 15 through a sealing ring 18; the upper cover plate A rotating column 2 is rotatably connected at the center of the top of 15; the bottom end of the rotating column 2 is convex; the bottom of the rotating column 2 is located in the annular tube 17; a limiting column 21 is provided in the annular tube 17, and the top of the limiting column 21 is concave, and the convex part of the rotating column 2 extends into the concave part of the limiting column 21; an annular groove 26 is provided on the outer wall of the convex part of the rotating column 2, and a magnetic ring 27 is rotatably connected to the annular groove 26, and the top of the annular groove 26 is magnetic, and the magnetic ring 27 and the top of the annular groove 26 attract each other; a group of threaded grooves 25 are provided on the magnetic ring 27; a threaded column 24 is threadedly connected to the limiting column 21, and the threaded column 24 The rotating column 2 is threadedly connected to the thread groove 25; the rotating column 2 is rotated by the power member, and when the rotating column 2 rotates, the limiting column 21 is driven to rotate through the connecting member; a group of cleaning plates 22 are fixedly connected to the outer wall of the limiting column 21, and a group of cleaning plates 22 and a group of lamp body plates 14 are placed in a staggered position, and a liquid spraying part is provided on the cleaning plate 22; in the prior art, the light-transmitting plate of the explosion-proof lamp used in the chemical workshop is generally made of non-glass material, which has a certain adhesion when broken, and can avoid splashing caused by the breakage of the light-transmitting plate, but there are the following problems: first, in order to avoid the explosion-proof of the lighting lamp body plate, the light-transmitting plate is thicker, but because it is used in the chemical workshop In the room, there are corrosive gases or liquids, etc. If the surface of the light-transmitting plate is not wiped and cleaned for a long time, it is easy to cause surface bumps, which affects the light transmission effect of the lamp body and causes shadow spots; secondly, the existing cleaning is generally done by manual wiping, but for a large number of lighting lamps located at high places, manual wiping is inconvenient; for this reason, when the present invention is working, the handle 19 can be fixedly connected or rotatably connected, because in the chemical workshop, the position of the lighting light is different, one is on the tool table or the operating table, for desktop supplies or experimental lighting, and the other is located at a high place, for overall environmental lighting, so the handle 19 can be processed according to actual use;When the explosion-proof lamp is installed at a high place to illuminate the overall environment, the limiting column 21 can be driven to rotate through the rotating parts and the connecting parts. The limiting column 21 rotates to drive the cleaning plate 22 to wipe the surface of the light-transmitting plate 12. At the same time, the liquid is sprayed by the spray part during wiping, so that the surface of the light-transmitting plate 12 can be wiped optimally (it is difficult to clean some chemicals by simply wiping). At the same time, the limiting column 21 is installed on the magnetic ring 27 of the rotating column 2. At this time, it is installed in the threaded groove 25 of the magnetic ring 27 through the threaded column 24 to ensure that the limiting column 21 does not fall off. At the same time, the magnetic ring 27 is adsorbed in the annular groove 26. When the subsequent limiting column 21 is disassembled to clean the cleaning plate 22, the magnetic ring 27 is unlikely to shift in position, which facilitates the subsequent installation of the limiting column 21; at the same time, a group of lamp body plates 14 of the lighting module 13 are distributed in an arc-shaped isosceles trapezoid. When the cleaning plate 22 is not in a cleaning state, the cleaning plate 22 and a group of lamp body plates 14 are in a staggered distribution state, and there will be no light blocking. At the same time, the setting of the annular cylinder 17 can ensure the sealing of the position of the lighting module 13 and the lamp body plate 14, avoiding corrosion caused by the entry of some chemical substances, and the setting of the heat sink 11 can ensure the heat dissipation effect of the explosion-proof lamp. ;

[0036] The power part includes a servo motor 3; a cover body 16 is fixedly connected to the upper cover plate 15; a first gear 31 is fixedly connected to the outer wall of the rotating column 2; a servo motor 3 is fixedly connected to the inner wall of the top end of the cover body 16, and the servo motor 3 is fixedly connected to the second gear 32 through a rotating shaft; the second gear 32 and the first gear 31 are meshed with each other; a handle 19 is provided on the outer wall of the cover body 16;

[0037] The connecting member includes a positioning block 35; a group of first grooves 34 are opened on the outer side wall of the convex part of the bottom end of the rotating column 2; the positioning block 35 is fixedly connected to the bottom of the first groove 34 through a spring; the first electromagnetic layer 36 is fixedly connected to the bottom of the first groove 34, and when the first electromagnetic layer 36 is energized, the positioning block 35 and the first electromagnetic layer 36 repel each other; a group of positioning grooves 33 are opened on the inner wall of the concave part of the limiting column 21; the positions of the positioning grooves 33 and the first grooves 34 correspond to each other;

[0038] A group of first through grooves 4 are provided on the outer wall of the cover body 16; a group of first slide grooves 41 are provided on the top of the upper cover plate 15; a pair of symmetrically distributed first sliders 42 are slidably connected in the first slide grooves 41, and the first sliders 42 are fixedly connected to the inner wall of the first slide grooves 41 through springs; a slide plate 43 is fixedly connected to the pair of first sliders 42, and the slide plate 43 extends out of the cover body 16 through the first through grooves 4, and a first inner arc surface 44 and a second outer arc surface 45 are provided at the end of the slide plate 43, and the pair of slide plates 43 are symmetrically arranged, and a pair of adjacent first inner arc surfaces 44 form an inner arc groove 46; a fixing column 47 is fixedly connected to the end of the cleaning plate 22, and the fixing column 47 and the inner arc groove 46 correspond to each other; a group of the inner arc grooves 46 positions and a group of the lamp body plate 14 positions are staggered;

[0039] The first slider 42 is magnetic; a second electromagnetic layer 48 is fixedly connected to the side wall of the first slide groove 41 away from the center point of the upper cover plate 15; when the second electromagnetic layer 48 is energized, the second electromagnetic layer 48 and the first slider 42 repel each other;

[0040] Situation 1: When the explosion-proof lamp is placed on a tool bench or an operating table for lighting desktop items or experiments, the light-transmitting plate 12 should be kept bright at all times, that is, it can be manually wiped at any time. At this time, the blocking block 35 is located in the first groove 34, and the cleaning plate 22 can be manually rotated. At this time, the limiting column 21 and the magnetic ring 27 rotate, and the rotating column 2 is in a fixed state ((the magnetic adsorption of the magnetic ring 27 is not fixed, and the magnetic ring 27 can still rotate under the action of external force. At the same time, the rotation of the rotating column 2 can only be driven by the servo motor 3. Because the servo motor 3 has a braking unit inside the body (the prior art is not described), the rotation of the rotating column 2 cannot drive the servo motor 3 to rotate. Therefore, when the servo motor 3 is not working, the rotating column 2 is in a stationary state)), the cleaning plate 22 is manually rotated, and after cleaning, the fixed column 47 is allowed to stay in the inner arc groove 46 formed by a pair of first inner arc surfaces 44, and When rotating, by utilizing the setting of the first inner arc surface 44 and the second outer arc surface 45 (when rotating, the fixed column 47 first comes out of the inner arc groove 46, and finally enters the inner arc groove 46 through the second outer arc surface 45), it can ensure that the position where the cleaning plate 22 stays is in a misaligned state with the lamp body plate 14, and at the same time, it can also effectively ensure the stable state of the cleaning plate 22 (the stable state of the cleaning plate 22 is fixed by the inner arc groove 46 formed by a pair of slides 43, and the fixed column 47 is stabilized by the spring force on the first slider 42). Only when there is an external force, the fixed column 47 has an external rotational force, which can make the fixed column 47 be pushed out of the inner arc groove 46 for cleaning, without affecting the manual wiping state, ensuring the timeliness, and thus ensuring the anytime brightness of the operating table and the tool table (the adsorption force of the magnetic ring 27 is small and does not affect the manual rotation, nor does it affect the rotation driven by the servo motor 3).

[0041] Case 2: When the explosion-proof lamp is installed at a high place to illuminate the overall environment, there is no need to wipe it at any time, only intermittent wiping is required. At this time, the servo motor 3 will work intermittently. During operation, the first electromagnetic layer 36 and the second electromagnetic layer 48 are energized first, and the first electromagnetic layer 36 and the positioning block 35 repel each other, allowing the positioning block 35 to extend into the positioning groove 33. At the same time, the second electromagnetic layer 48 and the first slider 42 repel each other, allowing a pair of slides 43 to separate from the fixed column 47, and then the servo motor 3 meshes with the first gear 31 and the second gear 32, thereby rotating the rotating column 2, and the rotating column 2 rotates. The rotation of the moving column 2 will be located in the locking groove 33 through the locking block 35, so that the limiting column 21 can rotate accordingly. At the same time, the contraction of the slide plate 43 can effectively avoid the interference of the inner arc groove 46 and the second outer arc surface 45 on the rotation of the cleaning plate 22. At the same time, the servo motor 3 has precise positioning, which can ensure that when it stops rotating subsequently, that is, when the first electromagnetic layer 36 and the second electromagnetic layer 48 are in a power-off state, a pair of slide plates 43 are extended under the action of the spring force, so that the fixed column 47 is located between the pair of slide plates 43 again, and the stable placement of the cleaning plate 22 is ensured again.

[0042] The top-view cross-section of the locking block 35 is an isosceles trapezoid; during operation, in order to avoid a slight offset of the fixed column 47, the top-view cross-section of the locking block 35 is an isosceles trapezoid. When the locking block 35 is pushed out by the magnetic repulsion of the first electromagnetic layer 36, if the fixed column 47 is slightly offset, that is, the locking groove 33 on the limit column 21 is slightly offset, the locking block 35 can still be snapped into the locking groove 33 by the repulsive force, and the locking block 35 will not be unable to be snapped into the locking groove 33 due to the corresponding offset of the positions of the first groove 34 and the locking groove 33, thereby ensuring the stable rotation and cleaning of the cleaning plate 22.

[0045] The extrusion unit includes a sliding column 591; an annular corrugated groove 57 is provided at the bottom end of the annular housing 1; a third cavity 58 is provided in the cleaning plate 22; a push block 59 is slidably connected to the third cavity 58, and the push block 59 extends into the second cavity 51; the extrusion plate 54 is slidably connected to the side wall of the push block 59; a through groove is provided at the top of the third cavity 58; a sliding column 591 is fixedly connected to the push block 59, and the sliding column 591 extends into the annular corrugated groove 57 through the through groove; a group of inclined grooves 56 are provided on both side walls of the second cavity 51; guide columns 55 are fixedly connected to both side walls of the extrusion plate 54, and the guide columns 55 are slidably connected in the inclined grooves 56;

[0046] The switch member includes a first rubber column 63 and a second rubber column 64; the cross-sections of the top opening of the second groove 62 and the bottom opening of the circular through groove 61 are both isosceles trapezoidal; the first rubber column 63 is fixedly connected to the bottom of the second groove 62 by a spring; a baffle 65 is fixedly connected in the circular through groove 61, and the baffle 65 is fixedly connected to the second rubber column 64 by a spring; the cross-sections of the first rubber column 63 and the second rubber column 64 are isosceles trapezoidal, and when the limit column 21 and the rotating column 2 are not connected by the threaded column 24, the first rubber column 63 seals the second groove 62, and the second rubber column 64 seals the bottom end of the circular through groove 61, and when the limit column 21 and the rotating column 2 are connected by the threaded column 24, the first rubber column 63 and the second rubber column 64 fit each other, and at the same time open the second groove 62 and the circular through groove 61, so that the second groove 62 and the circular through groove 61 are connected to each other; a one-way valve is provided in the first hose 592 and the second hose 66;

[0047] During operation, since the limiting column 21 and the rotating column 2 are connected to each other through the threaded column 24 and the threaded groove 25, the limiting column 21 can be disassembled, and then the wiping layer 23 can be replaced (the threaded groove 25 is half without grooves and half with grooves. During installation, the end of the threaded column 24 first enters the position of the threaded groove 25 without grooves. At this time, the limiting column 21 and the rotating column 2 are in a fitted state to prevent liquid from flowing out; the material of the wiping layer 23 is absorbent and flexible, and can be a sponge or other material). 2 is in the separated state, at this time, the first rubber column 63 seals the second groove 62, and the second rubber column 64 seals the bottom end of the circular groove 61, and the liquid will not flow out. At the same time, when the limiting column 21 is installed on the rotating column 2 through the threaded column 24 and the threaded groove 25, the first rubber column 63 and the second rubber column 64 push each other, so that the second groove 62 and the circular groove 61 are in a connected state, and the liquid in the liquid box 6 can enter through the circular groove 61, the second groove 62 and the second hose 66 The liquid capsule 53, when the cleaning plate 22 rotates, the sliding column 591 pushes back and forth in the annular corrugated groove 57, so that the push block 59 drives the extrusion plate 54 to push back and forth. Because the guide column 55 on the extrusion plate 54 is slidably connected in the inclined groove 56, the extrusion plate 54 will also move up and down when following the push block 59 to push back and forth, and then squeeze the liquid capsule 53, so that the liquid in the liquid capsule 53 enters the first cavity 5 through the first hose 592, and then sprays out on the surface of the light-transmitting plate 12 through the spray hole 52, which is convenient for dissolving some chemical substances and facilitating the cleaning operation of the wiping layer 23; at the same time, the liquid tank 6 is connected to the outside through the switch valve 67. When the explosion-proof lamp is located at a high place and illuminates the whole, the liquid can be introduced regularly through the external line pipe at this time, and when operating the operating table or tool table, the liquid can be manually injected; at the same time, in different chemical workshops, different liquids can be injected corresponding to different chemical substances to dissolve the surface substances of the light-transmitting plate 12 in a targeted manner to avoid corrosion.

[0048] Working principle: When the explosion-proof lamp is installed at a high place to illuminate the overall environment, there is no need to wipe it at any time, only intermittent wiping is required. At this time, the servo motor 3 will work intermittently. When working, the first electromagnetic layer 36 and the second electromagnetic layer 48 are energized first, and the first electromagnetic layer 36 and the positioning block 35 repel each other, allowing the positioning block 35 to extend into the positioning groove 33. At the same time, the second electromagnetic layer 48 and the first slider 42 repel each other, allowing a pair of slides 43 to detach from the fixed column 47, and then the servo motor 3 engages with the first gear 31 and the second gear 32 to rotate the rotating column 2. The rotation of the rotating column 2 will be located in the positioning groove 33 through the positioning block 35, so that the limiting column 21 will follow the rotation. At the same time, the contraction of the slide 43 can effectively avoid the inner arc groove 46 and The second outer arc surface 45 interferes with the rotation of the cleaning plate 22, and the servo motor 3 has precise positioning, which can ensure that when the rotation stops subsequently, that is, when the first electromagnetic layer 36 and the second electromagnetic layer 48 are in a power-off state, the pair of slides 43 are extended under the action of the spring force, so that the fixed column 47 is located between the pair of slides 43 again, and the placement of the cleaning plate 22 is ensured to be stable again; because the limit column 21 and the rotating column 2 are connected to each other through the threaded column 24 and the threaded groove 25, the limit column 21 can be disassembled, and then the wiping layer 23 can be replaced (the material of the wiping layer 23 has adsorption and flexibility, and can be a sponge or other material). When the limit column 21 and the rotating column 2 are in a separated state, the first rubber column 63 seals The second groove 62 and the second rubber column 64 seal the bottom end of the circular groove 61, and the liquid will not flow out. At the same time, when the limiting column 21 is installed on the rotating column 2 through the threaded column 24 and the threaded groove 25, the first rubber column 63 and the second rubber column 64 push each other, so that the second groove 62 and the circular groove 61 are in a connected state. At this time, the liquid in the liquid tank 6 can enter the liquid bag 53 through the circular groove 61, the second groove 62 and the second hose 66. When the cleaning plate 22 rotates, the sliding column 591 circulates back and forth in the annular corrugated groove 57, allowing the push block 59 to drive the extrusion plate 54 to push back and forth. Because the guide column 55 on the extrusion plate 54 is slidably connected in the inclined groove 56, the extrusion plate 54 is following As the push block 59 is pushed back and forth, it also moves up and down, thereby squeezing the liquid capsule 53, allowing the liquid in the liquid capsule 53 to enter the first cavity 5 through the first hose 592, and then be sprayed onto the surface of the light-transmitting plate 12 through the spray hole 52, so as to facilitate the dissolution of some chemical substances and the cleaning operation of the wiping layer 23; at the same time, the liquid tank 6 is connected to the outside world through the switch valve 67. When the explosion-proof lamp is located at a high place and illuminates the whole, the liquid can be introduced regularly through the external inline pipe, and when operating the operating table or tool table, the liquid can be manually injected; at the same time, in different chemical workshops, different liquids can be injected corresponding to different chemical substances to dissolve the substances on the surface of the light-transmitting plate 12 in a targeted manner to avoid corrosion.
