Description

Laboratory water jet angle-variable bracket

Technical Field

The utility model relates to a laboratory water conservancy auxiliary device that punches a hole.

Background

In China, gas disasters are serious in the coal mining process, and serious threats are caused to the life and property safety of workers. At present, mine gas in China is mainly extracted by drilling, but because coal seam gas has the characteristics of high adsorbability and low permeability, certain difficulty is brought to gas extraction, and a water jet permeability-increasing technology is popularized as a measure capable of effectively promoting gas extraction. However, since most of research on hydraulic fracturing technology is theoretical analysis and field practice at present, safety problems of relevant experiments performed in a laboratory are much smaller compared with field practice, but less research is performed in the laboratory at present, resulting in crude and shortage of relevant equipment in the laboratory.

Disclosure of Invention

The utility model aims at providing a laboratory water jet becomes angle formula support can realize realizing the efflux of fixed horizontal angle or vertical angle at certain angle within range.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a laboratory water jet angle-variable bracket is composed of a nozzle sleeve 1, a connecting column 2, a nozzle sleeve base 3, a connecting column baffle 4, a rotatable upright column 5, an upright column sleeve base 6, an angle scale a 8, a pointer a 9, an angle scale b10 and a pointer b 11, wherein the nozzle sleeve 1 and the connecting column 2 are welded and fixed; the connecting column 2 and the nozzle sleeve base 3 can rotate relatively; the connecting column baffle 4 is welded and fixed with the connecting column 2; the nozzle sleeve base 3 is welded and fixed with the rotatable upright post 5; the rotatable upright post 5 is vertically placed in the upright post sleeve base 6; the angle scale a 8 is vertically welded and fixed on the side surface of the nozzle sleeve base 3; the pointer a 9 is fixedly welded on the nozzle sleeve base 3, initially points at the zero scale of the angle scale a 8 and can rotate along with the nozzle sleeve base 3; the angle scale b10 is horizontally welded and fixed on the side surface of the upright post sleeve base 6; the pointer b 11 is welded and fixed right above the angle scale b10, is at zero scale initially, and can rotate along with the nozzle sleeve base 3.

Furthermore, the upper part of the nozzle sleeve 1 is provided with a threaded hole 7.

Furthermore, a threaded hole 7 is formed in the connecting column baffle 4.

Furthermore, a threaded hole 7 is formed in the column sleeve base 6.

Laboratory water jet becomes angle formula support, can realize the efflux of fixed horizontal angle or upper and lower angle at certain angle within range. During operation, the nozzle is fixed in the nozzle sleeve through the bolt that matches with the upper portion screw hole, because spliced pole and nozzle sleeve base can rotate relatively, angle about the rotatory nozzle sleeve can be adjusted, accurate angle is confirmed through angle scale a, after the angle is confirmed, fix the spliced pole through the bolt that matches with the screw hole on the spliced pole baffle, thereby the upper and lower angle of fixed nozzle, the same way, horizontal angle can pass through rotatory nozzle sleeve base, accurate angle is confirmed through angle scale b, after the angle is confirmed, fix through the bolt that matches of the screw hole of stand sleeve base side. The jet flow with a fixed horizontal angle or an upper angle and a lower angle is realized in a certain angle range.
