Background

Water delivery projects in cold regions are often influenced by ice in winter, water delivery under an ice cover can be adopted in regions with cold weather conditions, but for regions with relatively low cold weather conditions, such as North China plain, stable ice covers are often difficult to form in winter. Once the ice cover is broken, a large amount of ice moves along with the water flow to the downstream, the downstream ice conveying pressure is continuously increased, ice plugs or ice dam disasters are often formed by stagnation, submergence and accumulation at positions such as section change, bottom slope change and wading buildings (gates and bridges), the water section is blocked, the section overflowing capacity is reduced, and then flood disasters such as canal overflow and the like can be caused, so that the life and property safety of people is seriously threatened. Aiming at the problem of water delivery in the ice period in the cold regions, if high-temperature water can be injected into the water delivery channel by using the reservoir, the production amount of ice can be controlled, and ice-free water delivery is realized in winter, on one hand, the damage of an ice plug and an ice dam can be fundamentally avoided, on the other hand, the water delivery capacity of the project can be fully exerted, and the ice-free water delivery flow is nearly twice of that of water delivery under an ice cover.

Because the depth of the reservoir is large, even if the surface of the reservoir is frozen, the water temperature in the depth of the reservoir is still higher than the freezing point and is not frozen. Based on the method, in order to realize ice-free water delivery, water in the reservoir along the water delivery project can be utilized to provide heat energy for the water body in the channel. However, due to the influence of factors such as operation scheduling of the reservoir and the like, longitudinal water temperature distribution of the reservoir may change along with seasonal changes, and therefore a device capable of enabling a traditional reservoir water intake to dynamically adjust the water intake height along with the water temperature change is urgently needed.

One end of a water intake hose 101 is a water intake, the other end of the water intake hose is connected with a reservoir gate water intake, a top floating body 102 is positioned at the top of the water intake hose 101, a bottom rotating shaft 104 is fixed at the bottom of the reservoir through a bottom anchoring pile 103, the bottom rotating shaft 104 is connected with an underwater motor 106, one end of a bottom anchoring rope 105 is fixed on the bottom rotating shaft 104, the other end of the bottom anchoring rope is connected with the water intake of the water intake hose 101, and a lateral anchoring rope 108 is connected with a lateral anchoring pile 107 and the water intake of the water intake hose.

In the embodiment, the diameter of the water taking hose is 1.5 meters, the length of the water taking hose is 10 meters, the two lateral anchoring ropes are 17 meters long, and the total length of the bottom anchoring rope is 15 meters.

Because the distribution of reservoir temperature along with the degree of depth is influenced by many factors such as reservoir operation dispatch and changes, traditional reservoir gate water intaking elevation is fixed, therefore the temperature of intaking often is uncontrollable. In order to deal with the problem, the anchoring type water intake device of the embodiment is limited in the moving range by the lateral anchoring rope, the bottom rotating shaft is driven to rotate by the underwater motor, and the length of the bottom anchoring rope is further changed, so that the water intake depth of the water intake hose is changed under the combined action of the top floating body and the bottom anchoring rope, and the stability of the water intake posture is maintained.

Example 2:

a suspended variable-elevation water taking device for a reservoir is arranged on one side of a water taking opening of an existing gate of the reservoir, and specifically comprises a water taking hose 201, a bottom ballast 202, a water surface floating body 203, a water motor 204, a top rotating shaft 205, a top anchoring rope 206, a lateral anchoring pile 207 and a lateral anchoring rope 208, as shown in figures 2a and 2 b. Water intaking hose 201 one end is the water intaking mouth, and the other end is connected with traditional reservoir gate water intaking mouth, and bottom ballast 202 is located water intaking hose 201 water intaking mouth bottom, and surface of water body 203 floats in water intaking hose 201 water intaking mouth top surface of water, and motor 204 and top pivot 205 on water are all fixed on surface of water body 203, and the motor on water can drive the rotation of top pivot, and water intaking hose water intaking mouth top is connected through the top pivot to top anchor rope 206. The lateral anchoring rope 208 connects the lateral anchoring pile 207 and the intake hose intake.

In the embodiment, the diameter of the water taking hose is 1.5 meters, the length of the water taking hose is 10 meters, two lateral anchoring ropes with the length of 17 meters are installed, and the total length of the top anchoring rope is 8 meters.

Because the distribution of reservoir temperature along with the degree of depth is influenced by many factors such as reservoir operation dispatch and changes, traditional reservoir gate water intaking elevation is fixed, therefore the temperature of intaking often is uncontrollable. In order to deal with the problem, the suspension type water intake device of the embodiment is restrained by the lateral anchoring rope to the plane moving range, the top anchoring rope can be driven by the top motor positioned on the water surface floating body to change the length, so that the water intake of the water intake hose changes the water intake depth under the combined action of the bottom ballast and the top anchoring rope, and the stability of the water intake posture is maintained.

The lateral anchoring rope 309 connects the lateral anchoring pile 308 and the intake port of the intake hose 301.

In the embodiment, the diameter of the water taking hose is 1.5 meters, the length of the water taking hose is 10 meters, two lateral anchoring ropes with the length of 17 meters are arranged, and the total length of the air guide hose is 8 meters.

Because the distribution of reservoir temperature along with the degree of depth is influenced by many factors such as reservoir operation dispatch and changes, traditional reservoir gate water intaking elevation is fixed, therefore the temperature of intaking often is uncontrollable. In order to deal with the problem, the airbag type water intake device of the embodiment is restrained by the lateral anchoring rope in the plane moving range, the top anchoring rope can be driven by the motor positioned on the water surface floating body to change the length, so that the water intake of the water intake hose changes the water intake depth under the combined action of the balance weight and the top anchoring rope, and the water intake posture is maintained to be stable.
