Abstract

The utility model relates to a dam flow guiding device, which comprises a dam, a water inlet valve, a water pump, a drainage valve, a water guiding pipeline and a drainage pipeline. The dam flow guiding device is characterized in that the water guiding pipeline and the drainage pipeline are mounted along the inside, the top and the outside of the dam on a water stop side of the dam, the water inlet valve is mounted at a water inlet position of the water guiding pipeline inside the dam, the water pump and a water filling valve are mounted on the dam top and the water guiding pipeline in a connecting manner, the water pump is communicated with water flow inside the dam, the water filling valve is connected with the drainage valve via an overflow valve and the drainage pipeline outside the dam, and a power generating unit is mounted at a water outlet of the drainage valve. The dam flow guiding device is low in flow guiding cost, convenient in assembly, low in labor intensity, controllable in drainage volume and rapid in flow guiding, water lower than a spill gate can still be normally drained without danger or pollution, and the device is suitable for flow guiding and drainage of large, small and medium reservoirs and in dangerous sections such as a dammed lake and the like, and water diversion and flow guiding among isolating 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. dam body drainage system, comprise dam body, water intaking valve, water pump, draining valve and draw, drainage pipe, it is characterized in that: block in the dam of water side along dam body, dam crest outside the dam, be equipped with draw, 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, and 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.
