Description

Reservoir dredging and water recovery system

This creation is related to a device for pumping silt (sand), especially a system for pumping silt (sand) from the seabed and reservoirs, and recycling water.

Although Taiwan is an island and surrounded by the sea, the daily water for people's livelihood is mainly used by reservoirs for water supply. In addition to water supply, another important purpose of the reservoir is to generate electricity. However, due to climatic factors, when the reservoir is in the dry season, due to the lack of water in the reservoir, water supply in districts and water restrictions sometimes occur.

One of the reasons for the lack of water in the reservoir is that the soil and stones on the slopes of the catchment area enter the reservoir and cause siltation. This is because after heavy rains or typhoons, a large amount of driftwood flows into the reservoir, often causing earth-rock flows, making the reservoir siltation more severe, not only reducing the reservoir’s water storage capacity, and imbalances in the supply of water for people’s livelihoods, it may even cause the reservoir’s generator plant to fail to operate and generate electricity. The dredging of rivers and reservoirs has always been the primary issue that government water conservancy units urgently need to solve.

When removing silt (sand) in the reservoir, the usual method must first wash out the dead wood mixed with the silt or salvage it ashore. Therefore, professional divers, dredging equipment, etc. must be used, which is time-consuming, labor-intensive and costly. It is not economical and effective.

In order to solve the aforementioned problems of reservoir siltation and water storage, the government and the private sector have invested a lot of manpower and funds to renovate the reservoir and related measures. For example, the sand discharge tunnel for the Zengwen Reservoir that cost billions of NT dollars was completed. The project cost is too high to extend to all Reservoir, the dredging effect has yet to be verified whether it can achieve the expected purpose. Therefore, how to actively develop an economical and effective reservoir dredging device is still an urgent and important issue.

As mentioned above, in order to solve the aforementioned reservoir siltation and water storage problems, and to improve the existing dredging practices, this creation proposes a reservoir dredging and water recovery system, using the principle of siphon and connecting pipe, in addition to being used to solve In addition to the silt (sand) problem of the reservoir, it also guides the flow of soil, mud, branches and rocks on the surface of the soil on the mountain slope upstream of the reservoir to avoid flowing into the reservoir.

The reservoir dredging and water recovery system of this creation includes: at least one suction drainage pipe, which is set on the seabed; at least one airtight mud collection tank, through which the seawater containing silt is sucked to the airtight collection Mud pool, let the sludge settle on the bottom of the airtight mud collection tank, the airtight mud collection tank is set at the sea level; at least one water diversion pipe is set above the airtight mud collection bucket; a water storage area, It is set on the ground floor on land, and the water diversion pipe is used to divert seawater to the water storage area; a water diversion device is installed in the sea area; a water storage bucket is installed at a high place, and the water diversion device sucks the seawater in the water storage area to the storage area. Bucket, the seawater in the storage bucket is used for the sedimentation and silt removal tank (mud accumulation area) to discharge sludge and clear the tank.

The reservoir dredging and water recovery system created by this invention can effectively extract the silt from the seabed and reservoirs, keep the reservoir's water storage at a normal level, effectively exert the reservoir seedlings' flood prevention function and extend the life of the reservoir.

Another purpose of this creation is to have the function of building an island, that is, the silt extracted by the pump can be recycled and used to reclaim Haipu new land.
