Abstract
The utility model discloses a breeze pipe auxiliary smoke generating device, which comprises a hand-held type balloon, two check valves and a rubber hose, wherein the two check valves are respectively and coaxially arranged at the two ends of the hand-held type balloon, one check valve is used for one-way air inlet, and the other check valve is used for one-way air outlet; the one-way valve for one-way air outlet is connected with the rubber hose, and the length of the rubber hose is 200mm, and the inner diameter of the rubber hose is 5 mm. The device can improve the work efficiency of underground mine ventilation staff when amount of wind survey and leak the wind point and seek through control little tuber pipe position of fuming and the volume of fuming.
Description
Technical Field
The utility model relates to a device of being fuming is assisted to breeze pipe belongs to the detection device of underground mine tunnel ventilation situation.
Background
According to different production safety requirements of various regions of the underground mine, economic systematic management is carried out on a ventilation system, and the wind speed of partial roadways is controlled to be 0.25m/s at the lowest. Meanwhile, along with the progress of the mining activity and the existence of the ventilation pressure difference, a large number of air leakage channels exist in ventilation facilities, surrounding rock cracks, surface subsidence areas, covering layers, main ventilator accessories and the like of underground mines, and the ventilation safety of the mines is seriously influenced if the air leakage channels are not controlled. Aiming at the above situation, the ventilation staff is assisted by adopting the breeze pipe to smoke to identify the wind direction, measure the wind quantity, search the wind leakage point and the like. At present, when the micro-air pipe is used, the glass pipe is generally broken, and the medicine in the glass pipe is poured out to be in contact with air so as to generate smoke capable of tracking air flow. Generally, the smoke quantity of each micro-air pipe is about 1.5L, and when the method is used, because all the medicines are exposed in the air, a large amount of smoke is produced at the same time, so that the method is not beneficial to field wind speed measurement and search of local air leakage points.
Disclosure of Invention
An object of the utility model is to provide a device of giving off smoke is assisted to little tuber pipe can be through the position of giving off smoke and the volume of giving off smoke of control little tuber pipe, improves the work efficiency of underground mine ventilation staff when amount of wind survey and the point of leaking out is seeked.
The breeze pipe auxiliary smoke generating device for achieving the purpose comprises a handheld air pressing ball, two one-way valves and a rubber hose, wherein the two one-way valves are coaxially arranged at two ends of the handheld air pressing ball respectively, and one-way air inlet and the other one-way air outlet are formed; the one-way valve for one-way air outlet is connected with the rubber hose, and the length of the rubber hose is 200mm, and the inner diameter of the rubber hose is 5 mm.
When the device is used, the breeze pipe with two opened ends is connected with the rubber hose, the air ball is pressed by hands to generate positive pressure to close the one-way valve at the air inlet side, the one-way valve at the air outlet side is opened, air is uniformly ventilated to the breeze pipe through the rubber hose, and the generated smoke overflows through the breeze pipe. And releasing the air pressing balloon by hand, wherein the air pressing balloon generates negative pressure in the natural recovery process to close the air outlet side one-way valve, the air inlet side one-way valve is opened, and the air pressing balloon completes air supplement. When the air pressing ball supplies air and stops operating, the air circulation in the breeze pipe is avoided, so that the failure of the medicine in the breeze pipe can be prevented, and the service life is prolonged.
The existing breeze pipe auxiliary smoke generating device is adopted to directionally and quantitatively convey air into the breeze pipe at every time, and the smoke generated after chemical reaction of the medicine is output outwards in a linear mode, so that the smoke is in laminar flow motion in the air, the air flow is convenient to observe, meanwhile, the breeze pipe can be repeatedly used, and the material consumption is reduced. The auxiliary smoke generating device for the micro-air pipe is simple in structure and convenient to operate, and can enable the micro-air pipe to continuously output stable smoke to an area needing air flow or air leakage detection. The original using method needs to use one micro-air pipe for each detection, is not beneficial to searching fine air leakage points due to large smoke generation amount, and can continuously use each micro-air pipe for 1-2 hours after the auxiliary smoke generating device is used.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
A breeze pipe auxiliary smoke generating device is shown in figure 1 and comprises a hand-held type air pressing ball 1, two check valves 2 and a rubber hose 3, wherein the two check valves 2 are respectively and coaxially arranged at two ends of the hand-held type air pressing ball 1, one check valve is used for one-way air inlet, and the other check valve is used for one-way air outlet; the one-way valve for one-way air outlet is connected with the rubber hose 3, and the length of the rubber hose 3 is 200mm and the inner diameter is 5 mm.
