Abstract

The utility model relates to a dam body drainage device, which comprises a dam body, a water inlet valve, a water pump, a drain valve, and drainage and drainage pipes, and is characterized in that: The diversion and drainage pipelines are equipped with water inlet valves at the water inlets of the diversion pipelines in the dam, and water pumps and water injection valves are installed at the top of the dam connected with the diversion pipelines. The drain pipe of the drain valve is connected to the drain valve, and the water outlet of the drain valve is equipped with a generator set. The device has low drainage cost, convenient assembly, low labor intensity, and adjustable displacement; the drainage is rapid and the water below the overflow gate can still be discharged normally, without danger and pollution; the device is suitable for any large, medium and small reservoirs, weirs Diversion and drainage of dangerous areas such as Saihu Lake, diversion of water from mountains and ditches for irrigation and power generation.

Description

The dam body drainage system

Technical field

The utility model relates to the related facility of dam body, particularly a kind of dam body drainage system.

Background technology

Existing reservoir draining in flood season water conservancy diversion must be that water level reaches or is higher than the dam body Hongmen Gate that overflows, and water can be discharged, and the water that is lower than the Hongmen Gate that overflows then can not be discharged; Flood season, flood regular meeting burst at the dam body weak part, can not carry out water conservancy diversion control early when water level during near warning line even dam crest; Particularly natural calamity such as seismic activity causes and intercepts mountain valley, river valley or riverbed and form barrier lake, need employ a tremendous amount of manpower, material resources are broken the weir draining, and secondary danger is very big.

Summary of the invention

The purpose of this utility model is to solve the weak point that prior art exists, provide a kind of drainage cost low, rapidly and the water that is lower than the Hongmen Gate that overflows still can normally discharge, not have danger, free of contamination dam body drainage system.

The utility model provides following technical scheme according to siphon principle for achieving the above object: a kind of dam body drainage system, comprise dam body, water intaking valve, water pump, draining valve and drawing, drainage pipe, it is characterized in that: block along dam body in the dam of water side, dam crest is equipped with outside the dam and draws, drainage pipe, water intaking valve is equipped with at water inlet place in the water pipe embedded road, be connected with conduit pipe in dam crest portion water pump and water injection valve are housed, water pump is communicated with current in the dam, water injection valve connects draining valve through the drainage pipe outside overflow valve and the dam, and the delivery port of draining valve is equipped with generating set.

The utility model drainage cost is low, easy to assembly, labour intensity is little, displacement size is adjustable; Water conservancy diversion rapidly and the water that is lower than the Hongmen Gate that overflows still can normally discharge, not have danger, pollution-free; This device is fit to hazardous location drainage drainings such as any large, medium and small reservoir, barrier lake, the mountain on the other way round is irrigated and generating every ditch diversion water conservancy diversion.

Description of drawings

Accompanying drawing is the utility model structural representation.

The specific embodiment

Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, the utility model formation is further specified.

As shown in drawings, this dam body drainage system is mainly by dam body 1, water intaking valve F ₁, water pump 2, draining valve F ₄With draw, drainage pipe constitutes, block along trapezoidal dam body 1 in the dam of water side 1a, dam crest 1c 1b outside the dam be equipped with draw, drainage pipe, water intaking valve F is equipped with at water inlet 5 places of 1a conduit pipe in the dam ₁, be connected with conduit pipe in dam crest 1c portion water pump 2 and water injection valve F be housed ₂, water pump 2 is communicated with water injection valve F with current 4 in the dam ₂Through overflow valve F ₃And the drainage pipe of 1b connects draining valve F outside the dam ₄, draining valve F ₄Delivery port 6 turbine generation unit 3 is installed, the electricity that delivery port 6 sends, can be used for water pump for draw, the drainage pipe water filling.

During work, close water intaking valve F earlier ₁With draining valve F ₄, open water injection valve F ₂With overflow valve F ₃, so that when water pump 2 water fillings, discharge draw, the gas in the drainage pipe, improve waterflood injection rate; When water from overflow valve F ₃Overflow promptly draw, gutter fills with water, close water injection valve F this moment ₂With overflow valve F ₃, open water intaking valve F ₁With draining valve F ₄, water can be discharged from drainage pipe; Drainage is closed draining valve F after finishing ₄Perhaps open water injection valve F ₂Get final product.

Claims (1)

1. A dam body drainage device, comprising a dam body, a water inlet valve, a water pump, a drain valve, and a drain pipe, is characterized in that: along the dam body water blocking side, the dam crest until the outside of the dam is equipped with a drain, Drainage pipes, water inlet valves are installed at the water inlets of the water diversion pipes in the dam, and water pumps and water injection valves are installed at the top of the dam connected to the water diversion pipes.
