Problems solved by technology

[0003] In order to solve the technical problems that it takes a long time to re-supply water after the water supply is stopped and the drill pipe is connected, and the backwater in the drill pipe forms a negative pressure, which easily causes cinders and other sundries to be sucked into the water channel in the drill pipe and cause the water channel to be blocked, the purpose of the present invention is to provide a backwater prevention drill pipe

Abstract

The invention relates to an anti-backwater drilling rod. The anti-backwater drilling rod comprises a triangular tube, a male joint and a female joint, wherein the triangular tube is arranged horizontally; the male joint and the female joint are arranged at the two ends of the triangular tube correspondingly; the male joint and the female joint are tubular and are arranged coaxially with the triangular tube; the male joint and the female joint are communicated with the triangular tube, so that water flows through the female joint, the triangular tube and the male joint sequentially; an anti-backwater mechanism is fixedly arranged in the female joint through a clamp spring; the anti-backwater mechanism comprises a limiting tube penetrating through the female joint as well as a steel ball arranged in the limiting tube; a ball baffle is arranged at one end, near the male joint, of the limiting tube; a water baffle is arranged at the other end of the limiting tube; the water baffle is round; a round water inlet hole is formed in the middle part of the water baffle; the ball baffle is fixedly connected with the limiting tube; the water baffle and the limiting tube are integrally formed;and the diameter of the water inlet hole is less than the diameter of the steel ball.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a backwater preventing drill pipe. Background technique [0002] The gas produced in the process of coal mining has brought serious safety hazards to the safety of coal mine production. Therefore, gas drainage and dilution of gas-containing coal seams and rock formations are required during the mining process. Drainage and dilution of gas requires the drilling of gas discharge holes. When drilling, it is necessary to deliver water to the drill bit through the hollow drill pipe, which is used to lubricate and cool the drill bit while flushing and removing chips. As the drilling depth increases, the drill pipe needs to be added. When adding the drill pipe, it is necessary to stop the water supply. After the water supply is stopped, on the one hand, the water in the drill pipe will flow out, so that when the water is sent again, the water needs to fill the drill pipe again...
