Problems solved by technology

At the same time, because the gate is partially lifted at this time, the kinetic energy of the water is very large, and its energy is wasted in confrontation with the gate. If this part of energy can be utilized, the impact on the bottom of the gate will be reduced and the rational use will be made. energy, thus turning harm into benefit

Embodiment 1

[0029] like Figure 1-5 shown.

[0030] A graded water storage gate includes a gate body, a power generation device and a fishing device.

[0031] The gate body is provided with a plurality of gate notches on the lower side.

[0032] The power generation device includes a water wheel device and a generator set, the water wheel device includes a water wheel shaft, water wheel blades and a transmission shaft, the water wheel shaft is installed transversely at the middle and lower part of the gate gap, and the water wheel blades are installed On the water wheel shaft, one end of the transmission shaft is coaxially installed with the water wheel shaft, and the other end is coaxially installed with the input shaft of the generator set.

[0033] There are 4 fishing devices, all of which are arranged on the backwater side of the gate body, including a fishing box, a rotating device and a fish storage box. The side where the support rod is connected with the rotating shaft of the r...

[0041] A graded water storage gate includes a gate body, a power generation device and a fishing device.

[0042] The gate body is provided with a plurality of gate notches on the lower side.

[0043] The power generation device includes a water wheel device and a generator set, the water wheel device includes a water wheel shaft, water wheel blades and a transmission shaft, the water wheel shaft is installed transversely at the middle and lower part of the gate gap, and the water wheel blades are installed On the water wheel shaft, one end of the transmission shaft is coaxially installed with the water wheel shaft, and the other end is coaxially installed with the input shaft of the generator set.

[0044] There are 8 fishing devices, all of which are arranged on the backwater side of the gate body, including a fishing box, a rotating device and a fish storage box. The side where the support rod is connected with the rotating shaft of the rotating device is the release surfa...

Embodiment 3

[0052] like Figure 1-Figure 6 as shown, image 3 for figure 2 Schematic diagram of the overall fishing device structure of the fishing box on the left in the middle, figure 2 The fishing box on the right also has the same overall fishing device, the difference is that it rotates in the opposite direction, and the installation position of the spherical snap joint on the release surface is the same as that of the image 3 In contrast, it can ensure that when turning, the direction of the fish-entry surface is opposite to the flow direction of the vortex, and then the fish-entry surface will rotate upwards. When the fishing box rotates to the fixed point (the highest point), the release surface of the lower part will use One side is the shaft and the other side is opened due to the gravity of the card joint (mainly due to the cooperation between the gravity of the card joint itself and the card connection strength of the card interface. When there are fish in the fishing box...

Abstract

The invention relates to a hierarchical water storage gate. The hierarchical water storage gate comprises a gate body, a power generating device and a fishing device. The gate body, the power generating device and the fishing device are specifically arranged, so that the hierarchical water storage gate can perform power generation operation in a hierarchical water storage process, and further can perform fishing operation; and in this way, the gate is not damaged as the lower portion of the gate is bent while water passes through the lower portion of the gate for a long time, so that the purpose of turning harm into good is achieved.

Description

technical field [0001] The invention belongs to the field of water conservancy applications, and in particular relates to a graded water storage gate. Background technique [0002] Existing gates are plates that can move up and down, and in large-scale hydropower stations and large-scale water conservancy dam areas, many of them need to store water in stages. At this time, many gates in stages of water storage need to reasonably control the amount of water flowing through. The conventional practice in this field is not to fully lift the gate, and to reasonably limit the amount of water flowing through the raised height of the gate. However, the big disadvantage of this method is that the kinetic energy of the water will cause the lower end of the gate to deform (impact deformation) over time, so that the gate cannot be lifted over time. lowered into the lower pocket, resulting in damage to the gate. At the same time, because the gate is partially lifted at this time, the ki...
