Embodiment Construction
[0009] Using the pressure formed by the water level difference between the upstream and downstream of the reservoir dam body or the water level difference inside and outside the river dam, use the pipeline to press figure 1 Closed connection is carried out in the structural form of the pipeline. After the pipeline system is connected, it must be well sealed and air-tight. The lower part of the upstream hose (3) of the pipeline is tied with a rope, and the screen head (1) is extended into the bottom of the reservoir or river. In the silt layer, people swing the sand-absorbing range of the adjustable hose (3) on the boat or on the floating body (14). 8), manually or mechanically pour water from the water diversion valve (9), stop watering after the exhaust valve (8) exits the water, and close the exhaust valve (8) and water diversion valve (9), open the water outlet working valve (11 ), at the same time, the suction port check valve (2) is automatically opened, and the sand suct...

The invention relates to a self-absorbing reservoir river sediment removing pipeline system which mainly solves the problem of sediment accumulation of water-power engineering and rivers. By removing affection on engineering by sediment, ensuring limitless service life of engineering and removing the sediment, smoothness of the rivers and safety of a dam are ensured and threats to dike-like buildings and the inland from floods are removed. The self-absorbing reservoir river sediment removing pipeline system can also be used for introducing water and generating power by introducing water in special circumstances based on the reality, so that engineering cost is saved and resources are fully utilized. The self-absorbing reservoir river sediment removing pipeline system is characterized in that pressure formed by a water level difference between a water outlet and a water inlet in a sealed pipeline system is utilized and sucking and flowing motions can be generated in a pipeline by means of a water introducing and activating manner so as to suck out all the sediment from the bottom of a reservoir river. Due to the self-absorbing manner, equipment or energy is not needed. Thus, the self-absorbing reservoir river sediment removing pipeline system has the advantages of being low in cost, high in efficiency, easy to construct and the like. A sieving end (1), a check valve (2), a hose (3), an extended pipe (4), a floating carrier (5), a hose (6), a dam passing pipe (7), a gas exhausting valve (8), a water introducing valve (9), an extended pipe (10), a water outlet working valve (11), a hose (12), a filtering pool (13), and a boat or a floating body (14) are arranged in the system.
Description
technical field [0001] The self-priming reservoir river sediment removal pipeline system is mainly used to remove the sediment accumulated year by year in the reservoir of water conservancy and hydropower projects, dredge the river bed that increases year by year due to sediment deposition, diversion of water and power generation and other fields. Prolong project life, increase reservoir capacity and power generation by clearing, ensure smooth flow of rivers and inland safety of embankments by clearing, use for self-priming water diversion and diversion for power generation can reduce project cost according to local conditions, and make full use of resources. Background technique [0002] In addition to adopting the design of sand discharge bottom holes in current water conservancy and hydropower projects, there is no other better method to solve the problem of reservoir sedimentation. However, the sand discharge bottom hole can only remove a small amount of limited sediment...
