Embodiment 1

[0033] A full-face automatic spraying system without nozzles, including a main control box 1, a wireless infrared sensor 2 and a spraying structure 3 without a nozzle, the main control box is wirelessly connected with the wireless infrared sensor, and the main control box is also connected with the spraying structure without a nozzle.

[0034] The nozzle-less spraying structure includes a spraying pipeline, and the spraying pipeline includes an outer pipe 4, an inner pipe 5 is arranged inside the outer pipe, and there is a gap 6 between the outer pipe and the inner pipe.

[0035] A plurality of water outlets are opened on the inner pipe, and the water outlets are spirally arranged on the outer wall of the inner pipe.

[0036] A plurality of through holes are opened at the bottom of the outer tube, and the periphery of each through hole is gradually recessed inward to form a trumpet-shaped structure, and the through holes and the trumpet-shaped structure form the nozzle 7 .

[...

Embodiment 2

[0040] The structure of embodiment 2 is basically the same as that of embodiment 1, except that the water outlets are scattered on the outer wall of the inner pipe.

Embodiment 3

[0042] like image 3 , There are four spray pipelines, and the four spray pipelines connect end to end to form a square or rectangular fully enclosed spray space.

[0043] Both the main control box and the wireless infrared sensor are powered by a built-in intrinsically safe battery power supply, and the battery life can be used continuously for 1 year.

Abstract

The invention discloses a full-section nozzle-free automatic spray system. The full-section nozzle-free automatic spray system comprises a main control box, wireless infrared sensors and a nozzle-free spray structure, wherein the main control box is wirelessly connected with the wireless infrared sensors, and the main control box is further connected with the nozzle-free spray structure. The nozzle-free spray structure comprises a spray pipe, wherein the spray pipe comprises an outer pipe, and an inner pipe is arranged in the outer pipe; a gap is formed between the outer pipe and the inner pipe, and a plurality of water outlets are formed in the inner pipe; and a plurality of through holes are formed in the bottom of the outer pipe, the through hole is provided with a plurality of through holes, the periphery of each through hole is gradually recessed inward to form a horn-shaped structure, and the through holes and the horn-shaped structures constitute spouts. The nozzle-free spray structure of the system can realize spraying by using high pressure water, the inner pipe and the outer pipe, a nozzle does not need to be additionally installed, good economic benefits are achieved, the nozzle does not need to be disassembled for cleaning every day, time and labor are saved, and the nozzle-free spray structure is simple to manufacture and convenient to install, and has the same spraying effect as the nozzle and an excellent dust removal effect.

Description

technical field [0001] The invention relates to the field of coal mine spray systems, in particular to a full-section automatic spray system without spray heads. Background technique [0002] According to the requirements of the "Regulations on the Prevention and Control of Occupational Disease Hazards in Coal Mine Workplaces", at least two automatic control air flow purification water curtains should be installed on the return air lane of the coal mining face and the return air side of the tunneling face. At present, the ordinary automatic spray used in domestic mines needs to be connected to a 127V non-intrinsically safe power supply, and the sensor wiring process is complicated. When the automatic spray needs to be moved during the excavation of the excavation face or the mining process of the coal mining face, the workload is large, and the layout of the equipment cables is not good. Beautiful, but there are unsafe factors such as leakage and electrical explosion. Moreo...
