[0033] Please refer to Figures 1 to 4 , a damless hydroelectric power generation device provided in the embodiments of the present application includes a water diversion pipe 1, a water volume control box 2, and a water flow collection box 3; there are multiple water diversion pipes 1 arranged side by side in the river channel; the water volume control box 2 is located upstream of the river channel and is connected to the upper end of the water diversion pipe 1; a flexible water retaining device is arranged in front of the water volume control box 2, and the flexible water retaining device is used to control and guide the water flow to enter the water diversion pipe 1 through the water volume control box 2; the water flow collection box 3 is located downstream of the river channel and is connected to the lower end of the water diversion pipe 1, and a water turbine generator 4 is connected to the outlet of the water flow collection box 3.

[0034] It should be noted that this damless hydroelectric power generation device should be installed in a river section with a relatively large slope ratio and a certain flow rate. Multiple groups of relatively long water diversion pipes 1 can be installed at the edge of the river channel, and the length of the water diversion pipe 1 is subject to the vertical drop value between the uppermost end and the lowermost end meeting the requirements. Under the regulation of the flexible water retaining device, the water diversion pipe 1 plays the role of combining a water retaining dam and a water diversion canal. There is no need to build a water retaining dam, nor is there a need to additionally occupy land to build a water diversion canal, which saves costs and does not affect the fishery ecology.

[0035] According to some embodiments of the present application, the water diversion pipe 1 includes a plurality of water diversion pipe segments, and adjacent water diversion pipe segments are connected in series through pipe joints. Generally, multiple groups of water diversion pipe segments are arranged along the river course direction, and multiple water diversion pipes are formed by connecting in series through pipe joints. The pipe joints on the multiple water diversion pipes 1 are arranged at the same position in the length direction of the water diversion pipe, so that the length dimensions of multiple groups of water diversion pipe segments are the same, which is convenient for production and manufacturing and avoids the diversification of the length of the water diversion pipe segments.

[0036] According to some embodiments of the present application, a fixing plate is provided on the water diversion pipe 1, and the fixing plate is connected to the fixing piles 9 arranged on both banks of the river through steel wires 10, so as to fix the water diversion pipe 1 in the river. Specifically, a plurality of fixing holes for fixing the water diversion pipe 1 are formed on the fixing plate. The plurality of fixing holes can be evenly distributed, and the number is the same as the number of the water diversion pipes 1. The fixing plate can also adopt a combined structure, that is, it is composed of a plurality of slats with semi-circular grooves combined by screws 15. The opposite semi-circular grooves on adjacent two slats are spliced to form a fixing hole adapted to the diameter of the water diversion pipe 1. The fixing plate with this structure is convenient for installation. The four corners of the fixing plate are connected to a plurality of fixing piles 9 arranged on both banks of the river through steel wires 10.

[0037] According to some embodiments of the present application, there are a plurality of the fixing plates and they are arranged at intervals along the length direction of the water diversion pipe 1. By arranging a plurality of fixing plates at intervals along the length direction of the water diversion pipe, better fixation can be implemented on the entire length of the water diversion pipe, so as to avoid the displacement of the water diversion pipe in the river.

[0038] According to some embodiments of the present application, a part of the fixing plates is arranged at the pipe joints of the water diversion pipe 1. Specifically, the fixing plate can be divided into a first fixing plate 5 and a second fixing plate 6. Among them, the first fixing plate 5 is arranged at the pipe joint of the water diversion pipe 1 and is fixed to the first fixing plate 5 through the pipe joint. The first fixing plate 5 is connected to the fixing pile 9 to fix the water diversion pipe to prevent it from moving up, down, left and right; the second fixing plate 6 is arranged in the middle of each water diversion pipe segment, and the second fixing plate 6 is connected to the fixing pile 9 to fix the middle section of the water diversion pipe to prevent it from moving left and right.

[0039] According to some embodiments of the present application, a valve 7 is provided at the connection between the upper end of the water diversion pipe 1 and the water volume control box 2. By arranging a gate valve at the joint between the uppermost end of the water diversion pipe and the water volume control box, it is convenient to cut off the water flow of the water diversion pipe.

[0040] According to some embodiments of the present application, a valve 7 is provided at the connection between the lower end of the water diversion pipe 1 and the water flow collection box 3. By arranging a gate valve at the joint between the lowermost end of the water diversion pipe and the water flow collection box, it is convenient to cut off the water flow of the water turbine.

[0041] According to some embodiments of the present application, the water diversion pipe 1 can be a flexible pipe or a rigid pipe.

[0042] According to some embodiments of the present application, the inlet area of the water flow collecting box 3 is larger than the outlet area. Since the water flow collecting box 3 is arranged at the lowermost end of the water diversion pipe 1 to collect multiple water diversion pipes 1 into a single stream of water to enter the water turbine generator 4, the inlet area of the water flow collecting box 3 should be slightly larger than the outlet area, that is, the outlet area of the water flow collecting box 3 should be slightly smaller than the sum of the water flow areas of all the water diversion pipes 1. Specifically, the water flow collecting box 3 can be arranged in a conical structure with a larger upper part and a smaller lower part.

[0043] According to some embodiments of the present application, an interception net 8 is inclinedly arranged at the opening of the water volume control box 2. Specifically, the opening of the water volume control box 2 is an inclined section, with the side close to the river bank being higher than the side close to the river center, and the interception net 8 is arranged along the above-mentioned inclined section at the opening of the water volume control box 2. Since the water volume control box 2 is arranged at the uppermost end of the water diversion pipe 1 and the water volume control box 2 is connected to multiple groups of water diversion pipes 1, the excess water flows out from the water volume control box 2. At the same time, by inclinedly arranging the interception net 8 at the opening of the water volume control box 2, impurities and fish can be intercepted.

[0044] According to some embodiments of the present application, the flexible water retaining device is arranged in front of the interception net 8 and can change the speed, height, direction and flow rate of the water flow, so as to control and guide the water flow into the water diversion pipe 1. Specifically, the flexible water retaining device includes a column frame 11, a water retaining component 12 and a driving assembly. The column frame 11 is arranged above the river course, the water retaining component 12 is arranged on the side of the water volume control box 2 close to the river center, and the driving assembly includes multiple winches 13 arranged on both banks of the river course and is connected to the water retaining component 12 through steel wires 14 to control the position of the water retaining component 12, so as to change the speed, height, direction and flow rate of the water flow and control and guide the water flow into the water diversion pipe 1.

[0045] It should be noted that the structure and principle of this flexible water retaining device can refer to the patent application filed by the applicant that has been submitted but not yet published, with the application number 2024205046250, the application name being a flexible water retaining device, and the application date being March 15, 2024. Details will not be elaborated here.
