Abstract
A tension suction nozzle is provided with a center tube and a suction nozzle. The lower end of the center tube is cone, the end of the center tube is closed, openings are arranged on sides of the center tube, the suction nozzle is sleeved on the outer side of the lower end of the center tube, the upper portion of an inner cavity of the suction nozzle corresponds to the cone and is in the shape of funnel matching with the cone, the center tube is further fixedly connected with an outer sheath, the top of the suction nozzle and the top of an inner cavity of the outer sheath are fixedly connected with tension springs, and the upper end of the center tube is connected and communicated with a gas supply or liquid supply pipeline. The tension suction nozzle is simple in structure and use and automatic in closing, avoids spillage and wasting of oxygen or nutrient solution, simultaneously can be used for sucking the oxygen or nutrient solution smoothly, is an rescue and self-rescue important facility for personnel stranded by mine collapse and water permeation, and is wide in application.
Description
Technical field
The utility model relates to a kind of safety device for life-saving, is specifically related to the pulling force suction nozzle of a kind of mining area with oxygen uptake or suction nutrient solution.
Background technology
Landslide and permeable be the particularly serious accident of mining area underground work, often cause casualties, social influence is abominable, for saving the life of down-hole indicator of trapped personnel, races against time, and waits for rescue, and oxygen and nutrient solution need in time be provided.Therefore, the mining area must be equipped with oxygen channel, nutrient solution pipeline and the suction nozzle facility that matches with it at ordinary times.
Summary of the invention
The technical problem that the utility model will be saved is: solve the problem that above-mentioned prior art exists, and provide a kind of simple in structure, use simple, close automatic, broad-spectrum pulling force suction nozzle.
The technical solution adopted in the utility model is: this pulling force suction nozzle, have central tube and suction nozzle, the central tube lower end is a bullet, the termination sealing, the side perforate, suction nozzle is sleeved on the outside, central tube lower end, and suction nozzle inner chamber top is corresponding with bullet, is infundibulate, coincide with bullet, central tube also is fixedly connected with oversheath, and suction nozzle top and oversheath inner chamber top are fixedly connected with tension spring, and the central tube upper end connects with air feed or feed liquid pipeline.
In the technique scheme, suction nozzle inner chamber lower end also is equipped with the soft switch of moulding.
In the technique scheme, central tube upper end connects by tee pipe coupling and air feed or feed liquid pipeline.
In the technique scheme, the bullet outer wall of central tube also is equipped with the caulking gum layer.
The utility model is simple in structure, draw to next gently as long as contain suction nozzle during use with mouth, can be communicated with air feed or feed liquid pipeline, after unclamping, under the tension spring effect, automatically reset and close, avoid the loss waste of oxygen or nutrient solution, the utility model can make trapped miner rescue and save oneself and well be ensured with the mine oxygen supply with for the supporting use of rescue safety device pipeline of nutrient solution.
