Assembly type reservoir horizontal water inlet layout structure and operation method

Abstract

The invention discloses an assembly type reservoir horizontal water inlet layout structure. The assembly type reservoir horizontal water inlet layout structure comprises a bidirectional flange nodularcast iron pipe, a valve, a valve rod, a valve rod supporting seat and a control device; one end of the bidirectional flange nodular cast iron pipe is fixed to dam slopes at the two sides of a water inlet through expansion bolts; the other end of the bidirectional flange nodular cast iron pipe is connected with the valve through a bolt and a nut; and the valve is connected with a rotating hand wheel and a motor through the valve rod. All components can be prefabricated, need not to be welded in site in a remolding process of the original water inlet of a horizontal pipe of a reservoir and canbe connected directly. According to an operation method of the assembly type reservoir horizontal water inlet layout structure disclosed by the invention, the valve rod is driven by rotating the handwheel and the motor; the valve is opened or closed by virtue of remote control; and thus the personal security of an operator is guaranteed.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering facilities, and specifically refers to an assembly-type horizontal pipe water inlet arrangement structure of a reservoir, and also includes an operation method of the structure. Background technique [0002] Most of the small reservoirs in my country usually arrange horizontal pipes along the reservoir bank to take water in stages. Due to the long history of construction, the water inlet facilities are outdated and backward, and the structure is simple. They are mainly blocked by wooden plugs and concrete plugs, which need to be opened and closed manually, and sometimes manually. Underwater operation not only has high work intensity, but also has safety risks when it is opened, and personal safety accidents occur from time to time. At the same time, there are many problems such as theft of water inlet equipment, non-management personnel opening gates, reservoir water surges and cannot b...

[0002] Most of the small reservoirs in my country usually arrange horizontal pipes along the reservoir bank to take water in stages. Due to the long history of construction, the water inlet facilities are outdated and backward, and the structure is simple. They are mainly blocked by wooden plugs and concrete plugs, which need to be opened and closed manually, and sometimes manually. Underwater operation not only has high work intensity, but also has safety risks when it is opened, and personal safety accidents occur from time to time

At the same time, there are many problems such as theft of water inlet equipment, non-management personnel opening gates, reservoir water soaring and unable to close, etc., operation management is inconvenient and there are safety hazards
