Environment-friendly water-saving type infiltrating irrigation pipe with automatic adjusting function

Abstract

The invention relates to an environment-friendly water-saving type infiltrating irrigation pipe with an automatic adjusting function, which is used for carrying out infiltrating irrigation on various types of afforestation vegetation. The environment-friendly water-saving type infiltrating irrigation pipe comprises a pipe body, and is characterized in that a water outlet channel is formed on the pipe body along the length direction; an expansion groove with an opening being toward the outside of the pipe body is formed in one side of the pipe body along the water outlet channel; the expansion groove is only provided with the opening being toward the outside of the pipe body; a sealing edge which can be fitted with the outer wall of the expansion groove to close the water outlet channel is formed along the other side of the water outlet channel; the expansion groove is internally provided with an expansion body which can be expanded by absorbing water so as to enable the outer wall of the expansion groove to be is fitted with the sealing edge; a plurality of elastic resetting structures are arranged at the opening of the expansion groove. According to the environment-friendly water-saving type infiltrating irrigation pipe, the soil humidity can be detected by the expansion body, so that the opening and closing of the water outlet channel of the infiltrating irrigation pipe are controlled; irrigation is automatically carried out according to the soil humidity so that a lot of manual irrigation cost can be saved; the environment-friendly water-saving type infiltrating irrigation pipe has a simple structure and a scientific and reasonable design.

Description

technical field [0001] The invention relates to an environment-friendly and water-saving seepage irrigation pipe with an automatic adjustment function, which is used for underground seepage irrigation of various green vegetation. Background technique [0002] Seepage irrigation is an underground water-saving irrigation method, also known as underground drip irrigation. The seepage irrigation pipe can be roughly divided into two types: point type and line type. The point type (also known as the orifice type) is to use an impermeable plastic pipe to send water to the roots of the crops, and then slowly infiltrate through a kind of buried in the ground. Water seepage heads for irrigation. The line type (also known as the full-wall type) is directly irrigated by pipes buried in the ground that can slowly seep out. And this seepage pipe is divided into two kinds of porous pipes and microporous pipes. The porous pipe is a pipe made of many small holes (1-2mm in diameter) or 5-1...

Problems solved by technology

However, in the seepage irrigation pipe, the irrigation water must pass through the water-absorbing material to enter the soil. During the irrigation process, the water-absorbing material needs to repeatedly absorb water and expand, and the process is very complicated; and because the water-absorbing material contacts the soil and the pipe body at the same time In general, the pipe body is full of irrigation water. Therefore, the end of the water-absorbing swelling material that contacts the pipe body is often in a state of expansion, so that the input end of the irrigation water at the slit is often closed, affecting The sensitivity of self-regulation is improved; and the structure is complex, which is not conducive to production implementation
