Description

Technical Field

[0001] The present invention relates to the technical field of inclined shaft excavation in pumped storage power plants, and particularly to an electric slag discharging device in the inclined shaft TBM excavation of pumped storage power plants.

Background Art

[0002] Currently, pumped storage power plants are green, low-carbon, economical and highly reliable energy storage power sources in the new power system, and are currently the most large-scale developable power banks. The construction of inclined shafts is often a difficult point in the construction of pumped storage power plants and is often a major point in the control of the construction period. By utilizing TBM for the inclined shaft construction of pumped storage power plants, the construction efficiency can be improved, the construction risk can be reduced, and the construction period of the water diversion system can be shortened. By integrating multiple short inclined shafts into one long inclined shaft for TBM construction, the hydraulic loss of the water diversion system can be reduced, but the slag discharge at the gentle inclination angle of the long inclined shaft has become an important technical issue.

[0003] TBM is an abbreviation for "Tunnel Boring Machine". TBM is a dedicated mechanical equipment used for underground tunnel and piping works. Since TBM can excavate large-diameter tunnels underground, it can reduce the labor and time required for conventional blasting and manual excavation.

[0004] TBM usually consists of a circular cutting head (also called a shield machine) and a propulsion system located at the rear. The cutting head is equipped with a rotating cutter disk, penetrates underground rocks and soils, cuts them into small pieces, and removes crushed stones and mud from the tunnel through a transportation system. At the same time, the propulsion system moves the entire machine forward to enable the cutting head to continue excavating the tunnel.

[0005] The use of TBM in tunnel construction has advantages such as noise and vibration reduction, improved operating efficiency, and enhanced construction safety. In the case of the inclined shaft of a pumped-storage power plant, the TBM can excavate the underground part of the inclined shaft for installing the water turbine generator and related equipment.

[0006] In the construction of a long inclined shaft using a TBM, when the angle of the inclined shaft exceeds 50 degrees, the excavated materials can slide down automatically. However, as the inclination becomes gentler, the slag accumulates, and the conditions for the excavated materials to slide down automatically are not met. Therefore, an electric slag discharge device is required to solve the technical problem of slag discharge at a gentle inclination angle of the inclined shaft.

[0034] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the drawings. It should be noted that these embodiments are merely for explaining the present invention and do not limit the present invention.

[0035] In the description of the present invention, as points to be explained, the directions or positional relationships indicated by terms such as "center", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "ceiling", "bottom", "inner", "outer", etc. are directions or positional relationships based on the drawings, and are merely for the convenience of description and simplification of the description of the present invention, and do not explicitly or implicitly imply that the target device or member must have a specific direction and be configured and operated in a specific direction. Therefore, it should not be construed as limiting the present invention. Also, the terms "first", "second", etc. are merely for convenience of description and should not be construed as explicitly or implicitly indicating relative importance.

[0036] As points to be explained, in the description of the present invention, unless otherwise clearly defined and limited separately, the terms "attach", "be continuous with", "connect" should be construed in a broad sense. For example, it may be a fixed connection, a removable connection, or an integral one. Also, it may be a mechanical connection or an electrical connection. And it may be a direct continuity, an indirect continuity through an intermediate medium, or a communication inside two members. A person skilled in the art can interpret the specific meaning of the above terms in the present invention according to the specific situation.

[0037] Also, unless otherwise explained, in the description of the present invention, "a plurality" means two or more.

[0038] As shown in FIGS. 1 and 2, before explaining the electric slag discharge device in inclined shaft TBM excavation, first, the layout of the water intake system of the pumped-storage power station will be explained. As shown in FIG. 1, the water intake system of the pumped-storage power station mainly consists of an upper horizontal intake section, an upper inclined shaft section, a middle horizontal section, a lower inclined shaft section, and a lower horizontal section. In TBM construction, the upper horizontal intake section, the upper inclined shaft section, the middle horizontal section, and the lower inclined shaft section are integrated into a single long inclined shaft 3. The single long inclined shaft 3 has an upper ascending / discharge outlet 2 and a lower water intake lower horizontal tunnel 4 at the bottom.

[0039] When excavating a long inclined shaft with a gentle inclination angle during TBM construction, the excavated materials slide and discharge slag by their own weight. However, when the inclination angle is relatively gentle, slag is likely to accumulate, which affects the construction progress. To solve this technical problem, the present invention provides an electric slag discharge device in inclined shaft TBM excavation of a pumped-storage power station. This problem can be solved by the rotation and vibration of the rollers. It can prevent the accumulation of slag, ensure smooth slag discharge, and make the slag discharge safer and more environmentally friendly. Moreover, the construction by this device is simple and convenient and can be easily realized.

[0040] The electric slag discharge device 5 is arranged on the lower half circumference of the shaft wall of the long inclined shaft 3 and is arranged at intervals from top to bottom along the long inclined shaft. The radius of the electric slag discharge device 5 is customized according to the radius of the long inclined shaft and is not a variable diameter device. It is possible to further optimize it later and add a hinge connection and telescopic function to realize a variable diameter adjustment function. The specific structure of the electric slag discharge device 5 is shown in FIG. 1.

[0041] The electric slag discharge device 5 is supported on the shaft wall of the long inclined shaft 3 by a gripper 9. The gripper 9 is fitted into a groove 8 and, in specific implementation, can protrude from the groove 8 and be supported on the shaft wall of the long inclined shaft 3.

[0042] Inside the groove 8, an electric device 6 and a roller 7 are provided. The electric device 6 is serially connected to the roller by a connecting component 10. During the construction of the TBM tunneling machine, the electric device 6 can drive the roller 7 to operate and realize the automation function. When the roller 7 encounters the excavated material, the roller 7 can exert the functions of rotation and high-frequency vibration, and can smoothly slide down the excavated material. When there is no obstacle of the excavated material, the operation of the roller 7 stops. The electric device 6 and the roller 7 are connected to the groove 8 by a connecting component 10.

[0043] Specifically, as shown in FIGS. 1 to 2, in the electric slag discharging device for the inclined shaft TBM excavation of the pumped-storage power station, the electric slag discharging device 5 includes an arc-shaped segment and a groove 8. The outer wall of the arc-shaped segment is supported by a gripper 9 on the inner wall of the inclined shaft, and grooves 8 are provided at intervals on the inner wall of the arc-shaped segment. An electric device 6 and a roller 7 are provided in the groove 8.

[0044] The electric device 6 drives the roller 7 to rotate and / or vibrate, and moves the substances and materials in contact with the upper and both sides of the roller 7 downward along the inclined shaft.

[0045] When implementing the present application, it has the following features. Regarding the arc-shaped segment and the groove, the electric slag discharging device includes an arc-shaped segment and a groove. The outer wall of the arc-shaped segment is supported by a gripper on the inner wall of the inclined shaft, and grooves are provided at intervals on the inner wall. This structural design can adapt to the shape change of the inclined shaft, provide support and guiding functions, and ensure the stability and reliability of the device.

[0046] Regarding the electric device and the roller, an electric device and a roller are provided in the groove. The electric device is used to drive the roller to rotate or vibrate, and moves the substances and materials in contact with the upper and both sides of the roller downward along the inclined shaft. The rotation axis of the roller and the axis of the inclined shaft are perpendicular to each other and are two straight lines belonging to different planes. By adjusting the rotation angle of the roller, the descending speed and direction of the substances and materials can be controlled.

[0047] Regarding the configuration and combination, the electric slag discharging device is arranged on the lower half circumference of the shaft wall of the inclined shaft and is arranged at intervals from top to bottom along the inclined shaft. The electric slag discharging device is formed by combining a plurality of arc-shaped segments, and the radii of the inner and outer working surfaces of the device are adapted to the specification changes of the inclined shaft. With such a configuration and combination, it is possible to adapt to inclined shafts of various sizes and shapes, and improve the applicability and operating efficiency of the device.

[0048] Therefore, it has the following advantages.

[0049] Regarding the automation function, during the construction of the TBM tunneling machine, the electric device can drive the roller to operate and realize the automation function. Due to the rotation and vibration of the roller, the excavated materials contacted by the roller move downward along the inclined shaft, eliminating the need for manual cleaning and disposal of waste, and improving the efficiency and safety of the excavation process.

[0050] Regarding high adaptability, due to the flexible structural design and arrangement method of the electric slag discharging device, it can adapt to inclined shafts of different shapes and dimensions. The radii of the inner and outer working surfaces of the device can be adapted to the specification changes of the inclined shaft, ensuring a tight fit between the device and the inclined shaft, and reducing the risk of waste accumulation and blockage.

[0051] Regarding stability and reliability, the arc-shaped segments are supported by grippers on the inner wall of the inclined shaft, providing stable support and guiding functions. This structural design can reduce the rattling and vibration of the device during operation, and improve the stability and reliability of the device.

[0052] Regarding flexible adjustment, by adjusting the rotation angle of the roller, the dropping speed and direction of substances and materials can be controlled. This flexibility allows operators to adjust the device according to actual needs to adapt to different types of waste and crushed stones. The applicability and treatment effect of the device are improved.

[0053] Specifically, the rotation axis of the roller 7 and the axis of the inclined shaft are perpendicular to each other and are two straight lines belonging to different planes, which means that the rotation axis of the roller and the axis of the inclined shaft are not located on the same plane, and the two are intersecting but non-overlapping straight lines. This means that there is a perpendicular relationship between the rotation axis of the roller and the axis of the inclined shaft, and the two intersect perpendicularly. With this design, the roller can move in contact with the substances and materials in the inclined shaft in a vertical manner.

[0054] Specifically, the rotation axis of the roller 7 and the axis of the inclined shaft are perpendicular to each other, are two straight lines belonging to different planes, and the included angle between the two is 70° to 90°, including 90°. The included angle between the rotation axis and the axis of the inclined shaft is in the range of 70° to 90°, or exactly 90°. This setting can be adjusted according to specific needs. By changing the included angle between the roller and the axis of the inclined shaft, the falling speed and direction of the substances and materials can be controlled.

[0055] Specifically, the electric device 6 is serially connected to the roller 7 by the connecting component 10. The electric device 6 is connected to the roller 7 by the connecting component 10 and transmits electric power to the roller to drive it to rotate or vibrate. The connecting component may be a connecting shaft or a flexible shaft, and the specific selection depends on the application needs and design requirements.

[0056] Specifically, the electric slag discharging device 5 is arranged on the lower half circumference of the wall of the inclined shaft 3, and the inclination angle of the inclined shaft 3 is less than 50°. The electric slag discharging device 5 is arranged on the lower half circumference of the inclined shaft 3 to process the waste and crushed stones excavated from the upper part. At the same time, the inclination angle of the inclined shaft is limited to be less than 50° to ensure the stability and operating efficiency of the device.

[0057] Specifically, the electric slag discharging devices 5 are arranged at intervals from top to bottom along the inclined shaft 3. In order to effectively process the waste generated during excavation, the electric slag discharging devices 5 are arranged at intervals from the upper part to the lower part of the inclined shaft 3. According to this arrangement, it can be ensured that the waste is properly processed and removed during the falling process.

[0058] Specifically, the electric slag discharging device 5 is composed of a combination of a plurality of arc-shaped segments, and the radii of the inner and outer working surfaces of the electric slag discharging device 5 are adapted to the specification changes of the inclined shaft 3. The electric slag discharging device 5 is composed of a plurality of arc-shaped segments to adapt to the specification changes of the inclined shaft 3. The radii of the inner and outer working surfaces of these arc-shaped segments can ensure good compatibility between the device and the inclined shaft according to the specification changes of the inclined shaft.

[0059] Specifically, one end of the gripper 9 is embedded in the groove 8, and the other end of the gripper 9 is supported by the inner wall of the inclined shaft 3. With this structural design, the stability and supporting force of the electric slag discharging device can be improved, and it can be ensured that the device maintains a fixed position during the operation process.

[0060] Specifically, during the construction of the TBM tunneling machine, the electric device 6 drives the roller to operate, and an automated function can be realized. Due to the rotation and vibration of the roller 7, the excavated material contacted by the roller 7 is moved downward along the inclined shaft. The automated function can improve the construction efficiency, reduce the need for manual operation, and prevent the clogging of materials.

[0061] Specifically, the connecting component 10 is a connecting shaft.

[0062] Specifically, the connecting component 10 is a flexible shaft, and the application of this structure has the following characteristics.

[0063] Regarding the bending performance, the flexible shaft can operate in a curved or bent transmission path. It can adapt to non-linear layouts or curved layouts and realize transmission in complex geometric environments.

[0064] Regarding elasticity and flexibility, the flexible shaft is usually made of flexible materials such as elastic materials, rubber, or plastic, so it has a certain degree of elasticity and flexibility. Thereby, it can absorb vibrations, impacts, and torsional forces during the transmission process and provide a certain degree of vibration damping and buffering effect.

[0065] Regarding the torsional ability, the flexible shaft can withstand a certain amount of torsional force and transmit torque and rotational power. Usually, it has a certain torsional rigidity and can transmit torque and rotational motion during transmission.

[0066] Regarding weight reduction and flexibility, compared with the rigid transmission shaft, the flexible shaft is lighter, more flexible, and easier to install and adjust. According to the requirements of the transmission path, the flexible shaft can be bent or adjusted to adapt to different layouts and space constraints.

[0067] Regarding vibration absorption and noise reduction, due to its flexibility and elastic characteristics, the flexible shaft can reduce vibration and noise in the transmission system, absorb and disperse vibration and impact force from transmission parts, and reduce noise and vibration during the transmission process.

[0068] In the structure of this embodiment, the applied flexible shaft has the characteristics of excellent bending performance, elasticity and flexibility, torsional ability, weight reduction and flexibility, and vibration absorption and noise reduction in non-linear transmission.

[0071] In the second step, insert the electric slag discharge device 5. Insert the electric slag discharge device 5 into the inclined shaft 3 by a towing rope and arrange it at intervals. By properly arranging the device at different positions in the inclined shaft, the slag discharge effect of compensating for the non-uniformity of material and material discharge is realized.

[0072] In the third step, the electric slag discharging device 5 is fixed. The gripper 9 is opened and supported inside the wall of the inclined shaft 3 by pressure. The purpose of this step is to ensure the stability and fixity of the electric slag discharging device and maintain the correct position and posture during the operation process.

[0073] In the fourth step, the slag is discharged. After starting the electric device 6, when the excavated material encounters the roller 7, the rotation and high-frequency vibration of the roller 7 assist the sliding of the slag. The purpose of this step is to move the excavated material downward along the inclined shaft by the movement and vibration of the roller and achieve the effect of slag discharge.

[0077] During the construction of the TBM tunneling machine, the electric device 6 drives the roller 7 to operate, and an automation function can be realized. When the roller 7 encounters the excavated material, the roller 7 can exert the functions of rotation and high-frequency vibration and smoothly slide the excavated material. When there is no obstacle of the excavated material, the operation of the roller 7 stops.

[0078] The usage method of the electric slag discharging device in the inclined shaft TBM excavation of a pumped-storage power station includes the following first to fourth steps.

[0079] In the first step, make preparations in advance. Keep the electric slag discharging device 5 and the gripper 9 in an unactivated state, and embed the gripper 9 into the recessed groove 8.
