Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically to a riverbed-type powerhouse wastewater interception and discharge device arranged in conjunction with a sand-blocking embankment. Background Technology

[0002] In the design and construction of riverbed powerhouses, sediment traps and debris barriers are two crucial hydraulic structures. Together, they bear the important responsibility of protecting the powerhouse intake, maintaining the efficient operation of the turbines, and safeguarding the river's ecological environment. However, traditional layout methods usually set them up independently, which not only increases the complexity of the project but also brings many challenges. Sediment traps are usually placed at the bottom of the riverbed, adjacent to the powerhouse intake, and are composed of semi-gravity retaining walls. This structural design aims to effectively intercept sediment from upstream by utilizing the interaction between its own weight and the water flow, preventing it from entering the powerhouse intake. Debris barriers consist of end supports, cables in the middle, and buoys. The buoys float on the water surface and are connected to the supports by cables to form a floating interception barrier.

[0003] For some large riverbed-type power plants, the scale and technical requirements of debris barriers are significantly increased: the length of the debris barriers may exceed 300 meters, and the maximum tensile force can reach more than 200 tons. This places extremely high demands on the structural strength, stability of the supports, and reliability of the lifting equipment of the debris barriers. The supports of the debris barriers on both banks need to withstand huge horizontal tensile forces. Its structural design must consider multiple factors such as foundation bearing capacity, anti-sliding stability, and anti-overturning stability. In order to adapt to different water levels and the needs of cleaning and maintenance, the debris barriers need to be equipped with reliable lifting equipment, which further increases the complexity of the project and investment costs. Due to the large scale of the debris barriers, their construction costs are high, including material costs, construction costs, and equipment costs. In addition, independently set debris barriers also require additional supports and anchoring systems, which further increases the project investment.

[0004] Riverbed-type powerhouses are typically located near the riverbank, with both sand-trapping barriers and debris-blocking sluices arranged at an angle to guide silt and floating debris downstream through a sluice gate. Their axes are relatively close in spatial location, and the sand-trapping barrier, acting as a semi-gravity retaining wall, provides a certain level of horizontal tension during operation. This spatial relationship and structural characteristics make it possible to combine the sand-trapping barrier and debris-blocking sluices. Therefore, how to rationally combine the sand-trapping barrier and debris-blocking sluices has become a problem that needs to be discussed and exchanged among those in this technical field. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a riverbed-type wastewater interception and discharge device that is combined with a sand-trapping embankment. The wastewater interception and discharge device and the sand-trapping embankment are connected to the sand-trapping embankment via oblique ropes, vertical ropes, and pulleys. The semi-gravity retaining wall type sand-trapping embankment provides tension for the wastewater interception and discharge device. An automatic winch adjusts the oblique ropes and vertical ropes to meet the operating requirements of different water levels, thus solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To connect the debris-blocking float and the sand-blocking embankment to the sand-blocking embankment via diagonal ropes, vertical ropes, and pulleys, and to the semi-gravity retaining wall type sand-blocking embankment providing tension for the debris-blocking float, and to adjust the diagonal and vertical ropes by an automatic winch to meet the operating requirements of different water levels, this utility model provides the following technical solution: A riverbed-type powerhouse debris-blocking float device combined with a sand-blocking embankment, including a sand-blocking embankment, a debris-blocking float, and a powerhouse, wherein the sand-blocking embankment and the debris-blocking float are respectively connected to a bank slope and a guide wall at both ends, the debris-blocking float includes a buoy, an automatic winch, railings, and debris-blocking barriers, the automatic winch is equipped with diagonal ropes, vertical ropes, and pulleys, and the bottom of the sand-blocking embankment is equipped with anchor piles, which are connected to the sand-blocking embankment via diagonal ropes, vertical ropes, and pulleys.

[0009] Preferably, the sand-blocking embankment is located upstream of the power plant and arranged diagonally, with the end connected to the bank slope farther from the power plant and the side connected to the guide wall closer to the power plant. The debris discharge outlet is located above the sand-blocking embankment and is aligned with the plane direction of the sand-blocking embankment.

[0010] Preferably, the basic shape of the sand-blocking embankment is a semi-gravity retaining wall, divided into 15m sections, with a pulley installed at the top and bottom middle positions of each section.

[0011] Preferably, the debris barrier consists of a pontoon, a debris barrier, an automatic winch, and guardrails. The automatic winch is located at the middle of the top of the pontoon, the guardrails are located at the front and rear ends of the top of the pontoon, and the debris barrier is located at the front end of the bottom of the pontoon.

[0012] Preferably, the debris-blocking float is connected to the sand-blocking embankment via a central diagonal rope, a vertical rope, and a pulley. The debris-blocking sections are fixed to the diagonal ropes and buoys, and each section of the debris-blocking section is connected and locked to the adjacent debris-blocking section, so that the debris-blocking float is connected as a whole.

[0013] Preferably, the automatic winch can automatically wind up or unwind the rope to adapt to different water level requirements for debris interception.

[0014] Preferably, half of the anchor pile extends into the middle of the bottom of the sand retaining wall, and the other half extends into the rock. The anchor pile is located in the same plane as the inclined rope and the vertical rope.

[0015] Compared with the prior art, this utility model provides a riverbed-type wastewater interception and discharge device for factory buildings that is combined with a sand-trapping embankment, which has the following beneficial effects:

[0016] 1. This riverbed-type plant debris interception and discharge device, combined with a sand-trapping embankment, uses an automatic winch to adjust the diagonal and vertical ropes to meet different water level operating requirements. This is superior to the original sand-trapping embankment and debris interception and discharge arrangement. The automatic winch can automatically wind up or release the ropes to adapt to different water level debris interception requirements. When operating at high water levels (normal storage levels), the ropes are released using the automatic winch. At this time, the angle between the diagonal rope and the horizontal plane is larger, providing a smaller horizontal tension. When operating at low water levels (flood season restricted water levels), the ropes are wind up using the automatic winch. At this time, the angle between the diagonal rope and the horizontal plane is smaller, providing a larger horizontal tension, meeting the high flow velocity and high debris requirements during the flood season.

[0017] 2. This riverbed-type power plant debris interception and discharge device, combined with a sand-trapping embankment, optimizes the original layout and operation method, which relied on piers on both banks to provide horizontal tension and lifting equipment to meet different water level requirements. Instead, it utilizes multiple semi-gravity retaining wall-type sand-trapping embankments to provide tension for the debris interception and discharge device. The automatic winches on the debris interception and discharge device adjust the length of the vertical ropes to meet different water level operation requirements. This eliminates the need for piers on both banks and lifting equipment, reduces rope tension, lowers material requirements, solves the problems mentioned in the background technology, and provides a reasonable solution for the future layout of sand-trapping embankments and debris interception and discharge devices for riverbed-type power plants.

[0025] Please see Figure 1-5 This utility model provides a riverbed-type pollution interception and discharge device for a power plant, which is combined with a sand-blocking embankment. The device includes a sand-blocking embankment 1, a pollution interception and discharge 2, and a power plant 10. The sand-blocking embankment 1 and the pollution interception and discharge 2 are located upstream of the power plant 10. Both ends of the sand-blocking embankment 1 and the pollution interception and discharge 2 are connected to a bank slope 12 and a guide wall 11, respectively. Both the sand-blocking embankment 1 and the pollution interception and discharge 2 are divided into 15m sections. The pollution interception and discharge 2 includes a float 3, an automatic winch 8, railings 9, and a pollution barrier 4. The automatic winch 8 is equipped with an inclined rope 5, a vertical rope 7, and a pulley 6. Each section of the pollution interception and discharge 2 has the inclined rope 5, the vertical rope 7, and the automatic winch 8 located in the middle. The debris-blocking float 2 is connected as a whole by the debris-blocking wall 4. The sand-blocking embankment 1 is located at the bottom of the riverbed. The bottom of the sand-blocking embankment 1 is equipped with anchor piles 13, with one half of the anchor piles 13 extending into the bottom of the sand-blocking embankment 1 and the other half extending into the rock. The debris-blocking float 2 is located above the sand-blocking embankment 1 and is connected to the sand-blocking embankment 1 by the diagonal rope 5, the vertical rope 7 and the pulley 6. The semi-gravity retaining wall type sand-blocking embankment 1 provides tension for the debris-blocking float 2 so that the sand-blocking embankment 1 can block the silt and sand, and the debris-blocking float 2 can block floating objects.

[0026] Furthermore, the sand-blocking embankment 1 is located upstream of the power plant building 10 and is arranged diagonally. The end connected to the bank slope 12 is farther away from the power plant building 10, while the side connected to the guide wall 11 is closer to the power plant building 10. The debris-blocking float 2 is located above the sand-blocking embankment 1 and is aligned with the plane direction of the sand-blocking embankment 1. The sand-blocking embankment 1 and the debris-blocking float 2 are used in combination. The sand-blocking embankment 1 can block silt and sand, while the debris-blocking float 2 can block floating objects.

[0027] Furthermore, the basic shape of the sand-blocking embankment 1 is a semi-gravity retaining wall, divided into 15m sections. A pulley 6 is installed at the top and bottom middle of each section of the sand-blocking embankment 1. A semi-gravity retaining wall sand-blocking embankment 1 is set every 15m to block the mud and sand at different locations.

[0028] Furthermore, the debris barrier 2 consists of a pontoon 3, a debris barrier 4, an automatic winch 8, and railings 9. The automatic winch 8 is located at the top center of the pontoon 3, the railings 9 are located at the front and rear ends of the top of the pontoon 3, and the debris barrier 4 is located at the bottom front end of the pontoon 3. For rivers with low flow or little debris, the vertical ropes 7 and pulleys 6 can be omitted, and only the diagonal ropes 5 are set. To increase the stability of the pontoon 3, two diagonal ropes 5 are set on the sand-blocking embankments 1 at both ends to jointly tie the pontoon 3 to a single stress point, thereby increasing the overall stability of the debris barrier 2.

[0029] Furthermore, the debris-blocking float 2 is connected to the sand-blocking embankment 1 via the middle diagonal rope 5, vertical rope 7, and pulley 6. The debris-blocking bar 4 is fixed on the diagonal rope 5 and the float 3. Each section of the debris-blocking bar 4 is connected and locked to the adjacent debris-blocking bar 4, so that the debris-blocking float 2 is connected as a whole. The float 3 is inflatable, and the inflation amount of the float 3 can be controlled according to the water flow velocity and the amount of debris to meet the operating requirements of different water level conditions.

[0030] Furthermore, the automatic winch 8 can automatically wind up or release the ropes to adapt to different water levels and debris interception requirements. For shallower rivers without sand-blocking barriers 1, the bottom of the inclined ropes 5 and vertical ropes 7 can be fixed to the bottom of the river with anchor hooks, and the upper part can be the same as in Example 1, which can also meet the operational requirements.

[0031] Furthermore, half of the anchor pile 13 extends into the middle of the bottom of the sand retaining wall 1, and the other half extends into the rock. The anchor pile 13 is located in the same plane as the inclined rope 5 and the vertical rope 7, which helps to improve the stability of the anchor pile 13 during use. The inclined rope 5 or the vertical rope 7 being located in the same plane avoids the inclined rope 5 and the vertical rope 7 being subjected to forces in different directions.

[0032] In use, the debris-blocking float 2 and the sand-blocking embankment 1 are connected to the sand-blocking embankment 1 via diagonal ropes 5, vertical ropes 7, and pulleys 6. The semi-gravity retaining wall type sand-blocking embankment 1 provides tension for the debris-blocking float 2. The diagonal ropes 5 and vertical ropes 7 are adjusted by the automatic winch 8 to meet the operating requirements of different water levels. This arrangement is superior to the original sand-blocking embankment 1 and debris-blocking float 2 layout. The automatic winch 8 can automatically wind up or release the ropes to adapt to the debris-blocking requirements of different water levels. When operating at high water levels (normal storage water levels), the ropes are released by the automatic winch 8. At this time, the angle between the diagonal rope 5 and the horizontal plane is large, providing a smaller horizontal tension. When operating at low water levels (flood season restricted water levels), the ropes are wind up by the automatic winch 8. At this time, the angle between the diagonal rope 5 and the horizontal plane is small, which can provide a larger horizontal tension, meeting the operating requirements of high flow velocity and high debris during the flood season.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
