Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In this embodiment, an explosion-proof lamp is provided, as shown in fig. 1-3, where fig. 1, 2 and 3 show front view, side view and top view of the explosion-proof lamp respectively.
Specifically, it can be seen from the figure that the explosion-proof lamp comprises a lamp housing 1, an LED bulb 2, a porcelain lamp holder 3, a lamp shade 4 and a radiating tube 5. In this embodiment, the LED bulb 2 is wrapped up through the lampshade 4 and the lamp shell 1, the heat dissipation is assisted by the heat dissipation tube 5 in the aspect of heat dissipation, the two ends of the heat dissipation tube 5 are fixed on the two sides of the lamp shell 1, the inside of the heat dissipation tube 5 is communicated with the outside, the heat of the LED bulb is dissipated through the heat dissipation tube 5, the LED bulb 2 is prevented from being contacted with the outside, and the integral explosion-proof effect is improved. Specifically, the following is described.
The explosion-proof sealing joint 9 is arranged outside the lamp housing 1 and connected with the porcelain lamp holder 3 through a cable, and is used for providing power for the LED bulb 2 by an external power supply. The porcelain lamp holder 3 is installed inside the lamp housing 1 for installing the LED bulb 2. The top side of the lamp housing 1 is connected with a grounding row 11 for connecting with a ground wire.
In other embodiments, the explosion-proof lamp can be provided with a T8LED lamp tube, and the light source is efficient and energy-saving. The LED light source has the advantages of precisely controlling the light type and the light emitting angle of the LED light source through a unique light distribution design, avoiding light pollution and ineffective light utilization, along with soft light, no glare, no eye fatigue of operators and improvement of working efficiency.
In other embodiments, the lamp envelope 1 is die-cast from a lightweight aluminum alloy and the surface is treated with high voltage electrostatic spraying. A wiring cavity is arranged inside, and a special wiring terminal is connected with the explosion-proof sealing joint 9.
Illustratively, the edge of the lamp cover 4 is hinged to the top of the lamp housing 1, so that the lamp cover 4 is opened to replace the LED bulb 2. In order to improve the sealing effect, a sealing ring 7 for sealing the gap between the lamp housing 4 and the lamp housing 1 is provided at the bottom of the lamp housing 4.
On the other hand, in order to increase the explosion-proof effect, the components of the apparatus which may ignite the explosive gas mixture may be enclosed entirely in a housing, the lamp envelope 1 of which is capable of withstanding any joint or structural gap through the lamp envelope 1, the combustible mixture penetrating into the interior of the lamp envelope 1 explodes internally without damage, and it is ensured that the internal flame gas propagates through the gap with reduced energy insufficient to ignite the gas of the lamp envelope 1.
Optionally, the lampshade 4 is made of transparent toughened glass into a hemispherical shape, and the protective net 8 is wrapped outside the lampshade 4, so that the lampshade 4 can be protected.
In order to facilitate the fixing of the lamp housing 4, a locking catch 6 is provided between the lamp housing 4 and the lamp housing 1.
As shown in fig. 5, the shackle 6 includes a lock hook 61, a lock groove 62, and a screw. Wherein, the lock hook 61 is fixed at the edge of the lamp shade 4, and the lock groove 62 is arranged at the edge of the lamp housing 1; wherein, the side of the locking groove 62 is connected with a screw for locking the locking hook 61. The locking hook 61 is inserted into the locking groove 62, and the locking hook 61 is locked by a screw, thereby fixing the lamp housing 4.
Further, a sealing gasket 63 is provided inside the locking groove 62 for improving the sealing effect.
In other embodiments, the bolt-on flameproof housing has two types: a plane and a spigot.
For planar structures, the bolts not only perform fastening operations, but also ensure planar clearances.
For the spigot structure, when the explosion-proof surface only considers the cylindrical part, the bolt only plays a role in fastening; when the explosion-proof surface needs to consider the cylinder plus plane, the bolt not only performs fastening operation, but also plays a role in ensuring the clearance of the plane part. Care must be taken when tapping directly on the housing: the screw holes of the fastener do not need to pass through the explosion-proof shell as much as possible, and more than 3mm of allowance is reserved at the bottom of the screw holes when the fastener passes through the shell; when the light alloy material such as aluminum alloy is used as the explosion-proof shell, the strength of the aluminum alloy is lower, so that when the explosion-proof shell which is frequently opened (such as a light source is required to be opened when the light source is replaced) is fastened by using a screw, the screw hole strength is increased by embedding the anti-loose internal and external screw thread steel sleeve, and the screw hole is prevented from being failed due to thread tooth decay; the screw bolt which is not required to be opened by a user in the replacement of the light source or in the maintenance and is installed when leaving the factory can be directly tapped into the fastening screw hole, but the screw bolt cannot be used with fine threads, the screw bolt with rough threads is used as much as possible, and the number of the engaging buckles is enough to meet the fastening requirement.
In summary, when designing the housing fastener, it should be first clarified whether it is acting in the flameproof housing, only acting as a fastening, or both, and also acting as a fastening while ensuring the plane clearance, and then a proper bolt should be selected for determining the maximum axial load of the bolt.
In this embodiment, the heat dissipation of the LED bulb 2 is primarily assisted by the heat dissipation tube 5, and the communication of the outside air with the lamp housing 1 is avoided. The heat dissipation effect is achieved, the sealing performance is improved, and then the explosion-proof effect of the explosion-proof lamp is improved.
Fig. 4 is a schematic cross-sectional view of the lamp housing of the present utility model, as shown in fig. 4.
Fig. 4 also shows a sectional structure of the radiating pipe 5.
Specifically, in this embodiment, two ends of the heat dissipating tube 5 are fixed to two sides of the lamp housing 1, and the inside of the heat dissipating tube 5 is communicated with the outside, and an exhaust fan 10 is installed inside one end of the heat dissipating tube 5. The heat generated by the LED bulb 2 is conducted to the outside through the radiating pipe 5, and the exhaust fan 10 can accelerate heat radiation, so that the heat radiation effect is improved.
The heat of the LED bulb is radiated through the radiating pipe 5, so that the LED bulb 2 is prevented from being contacted with the outside, and the integral explosion-proof effect is improved.
Although embodiments of the present utility model 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 therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
