Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1-2, a dust protected flame-proof type LED lamp, including lamp body 1, lamp body 2 is installed to the lower extreme of lamp body 1, the lower extreme welding of lamp body 1 has a plurality of hollow protective rods 3, the common intercommunication of the lower extreme of a plurality of hollow protective rods 3 has dust collection box 5, aqua storage tank 4 has been seted up to the lateral wall of lamp body 1, and seted up water filling port 41 on the inner wall of aqua storage tank 4, water filling port 41 both can conveniently add water to aqua storage tank 4, still can keep interior outer atmospheric pressure balance of aqua storage tank 4 simultaneously, so that the hydroenergy in the convenient aqua storage tank 4 can be smoothly along hollow protective rods 3 flow direction dust collection box 5.

Pore 31 with aqua storage tank 4 intercommunication is seted up to hollow guard bar 3's upper end, it should be explained that, pore 31's aperture is minimum, therefore water in the aqua storage tank 4 when flowing downwards through pore 31 under the action of gravity, will form the continuous downward drippage of water droplet, both can fully contact and form the condensation nucleus with the dust in the air, simultaneously can make the hydroenergy in the aqua storage tank 4 enough flow the longer time, make this device can use the longer time, can also prolong the watered cycle in the aqua storage tank 4 greatly, reduce the trouble of manual maintenance. A plurality of through-holes 32 have been seted up to the lateral wall of hollow guard bar 3, and the internal top of dust collection box 5 inlays and is equipped with a plurality of strips 6 that absorb water, and the upper end of the strip 6 that absorbs water is close to lamp body 2, and the strip 6 that absorbs water adopts the polymer water-absorbent resin material to make, has stronger hydroscopicity, after the moisture evaporation of the strip 6 upper end that absorbs water, can draw moisture and supply.

This device is in the use, and the accessible water filling port 41 injects appropriate amount of water into aqua storage tank 4, because the aperture of pore 31 is minimum, and water in the aqua storage tank 4 can form the water droplet and follow hollow protection rod 3 and drip downwards when flowing to hollow protection rod 3 under the action of gravity.

When water drops flow in the hollow protection rod 3, the flow rate of the water drops in the hollow protection rod 3 is high, the flow rate of air outside the hollow protection rod 3 is low, and the flow rate of the air outside the hollow protection rod 3 is low, so that negative pressure can be formed in the through hole 32, the air outside the hollow protection rod 3 is pumped into the hollow protection rod 3 (the flow directions of the water drops and the air are shown as arrow directions in fig. 2), and dust in the air can be mixed with the water drops flowing in the hollow protection rod 3 to form condensation nuclei and flow into the dust collection box 5. With the continuous flow of the water droplets, the dust concentration in the air near the lamp body 2 can be effectively reduced to prevent the explosion when the concentration near the lamp body 2 is too high and the lamp body 2 generates heat.

When the condensation nucleus flows into the dust collection box 5, the condensation nucleus is gradually gathered together, dust in water is gradually deposited at the bottom in the dust collection box 5 after a period of time, water in the dust collection box 5 can rise along the water absorption strip 6 under the capillary action, and the water on the water absorption strip 6 is heated and evaporated because the water absorption strip 6 is close to the lamp body 2, so that the temperature near the lamp body 2 can be greatly reduced, the dust explosion caused by overheating of the lamp body 2 is prevented, the safety of the explosion-proof lamp is further improved, and the dust is collected in the dust collection box 5 along with the continuous evaporation of the water. Meanwhile, the lamp body 2 is cooled, the lamp body can be prevented from being damaged by high temperature, and the service life of the lamp body 2 is effectively prolonged. The device is very simple and safe to use, and only needs to add water into the water storage tank 4 at regular intervals and clean dust in the dust collection box 5.

Example two:

referring to fig. 3-5, different from the first embodiment, an annular groove 7 is formed at the inner bottom of the water storage tank 4, and a rotary ring 8 is hermetically and slidably connected in the annular groove 7, specifically, referring to fig. 5, the rotary ring 8 is hermetically embedded in the annular groove 7, so that water leakage in the water storage tank 4 can be prevented. A plurality of apopores 9 have been seted up to the upper end of change 8, hollow guard bar 3 is the same with apopore 9's quantity, and hollow guard bar 3 sets up under apopore 9, and the welding of hollow guard bar 3 is at the lower extreme of change 8, the lateral wall fixedly connected with blade 10 of hollow guard bar 3, specifically, the blade shape of wind cup can be made to blade 10, so can blow when coming at horizontal air current, can promote blade 10 and take place to rotate, thereby drive

change

8 and 3 circulations of hollow guard bar. In this embodiment, the water in the water storage tank 4 can flow from the water outlet hole 9 to the fine hole 31, and then continuously dropping water drops are formed in the hollow protection rod 3.

If wind blows in the use process of the lamp, the dust concentration of the air near the lamp body 2 is increased instantly, and the dust concentration is difficult to be processed in time by the devices in the first embodiment, so that the second embodiment is designed.

In this embodiment, when wind blows, the blowing blade 10 rotates to drive each hollow protection rod 3 and the rotating ring 8 to rotate around the lamp body 2 continuously, and during the fast rotation process of each hollow protection rod 3, the plurality of hollow protection rods 3 form a protection layer similar to a cylinder around the lamp body 2, so that the protection area of the hollow protection rods 3 is greatly increased to deal with the dust which is gathered fast. In the embodiment, when wind blows, the transversely blown air flow can directly pass through the through hole 32, dust in the air can also form condensation nuclei with dropped water drops when passing through the hollow protection rod 3, the mass of the dust is greatly increased after the condensation nuclei are formed, the dust cannot fly out along with the air flow, and the dust flows to the dust collection box 5 along the hollow protection rod 3 under the action of gravity.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
