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 discharge device in the inclined shaft TBM excavation of pumped storage power plants.

Background Art

[0002] At present, 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 pipeline construction. 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 has a rotating cutter head, penetrates underground rocks and soils and 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 whole machine forward so that the cutting head continues to excavate the tunnel.

[0005] The use of tunnel boring machines (TBMs) in tunnel construction offers advantages such as reduced noise and vibration, improved operational efficiency, and enhanced construction safety. In the case of pumped-storage power plant shafts, TBMs can excavate the underground portion of the shaft to install waterwheel generators and related equipment.

[0006] In the construction of long inclined shafts using TBMs, excavated material can automatically slide down when the shaft angle exceeds 50 degrees. However, when the slope becomes gentler, slag accumulates, and the conditions for the excavated material to automatically slide down are not met. Therefore, an electric slag removal device is needed to solve the technical challenge of slag removal at gentle inclined angles of inclined shafts. [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] In view of the above, and in response to the shortcomings of the prior art, the object of the present invention is to provide an electric slag discharge device and a method of using the same in TBM excavation of an inclined shaft of a pumped-storage power plant, in which an expansion excavation method is performed from top to bottom using a TBM after excavating a pilot shaft. The present invention provides an electric slag discharge device that assists in the sliding and discharge of slag due to its own weight when excavating a long inclined shaft at a gentle inclination angle. Slag accumulation is prevented by vibration of the electric roller, and smooth slag discharge is ensured.

[0008] The purpose of this application is to solve one of the problems in the background art. [Means for solving the problem]

[0009] The technical proposal adopted in this invention is as follows. In order to achieve the above objectives and other related objectives, the present invention provides an electric slag discharge device for TBM drilling in an inclined shaft of a pumped-storage power plant.

[0010] In an electric slag discharge device for TBM drilling in an inclined shaft of a pumped-storage power plant, the electric slag discharge device includes an arc-shaped segment and a recessed tank. The outer wall of the arc-shaped segment is supported by a gripper against the inner wall of the inclined shaft, and recessed tanks are provided at intervals in the inner wall of the arc-shaped segment. An electric device and rollers are provided inside the recessed tanks.

[0011] The electric device drives the rollers to rotate and / or vibrate, moving the material in contact with the rollers above and on both sides downward along the inclined shaft.

[0012] The gripper supports the electric slag discharge device on the tunnel wall of the long inclined shaft.

[0013] Regarding the electric motor and rollers, the electric motor is connected in series to the rollers by connecting components. The electric motor drives the rollers, and the rotation and vibration of the rollers cause the excavated material to slide down smoothly, thereby discharging the slag.

[0014] Regarding the grooves, the outer grooves connect to the gripper, while the inner grooves are used to secure the connecting member between the roller and the electric device.

[0015] The technical proposal provided in this application further has the following technical features.

[0016] Preferably, the axis of rotation of the roller and the axis of the inclined shaft are perpendicular to each other and are two straight lines belonging to different planes.

[0017] Preferably, the axis of rotation of the roller and the axis of the inclined shaft are perpendicular to each other, are two straight lines belonging to different planes, and the angle between them is 70 to 90°.

[0018] Preferably, the axis of rotation of the roller and the axis of the inclined shaft are perpendicular to each other, are two straight lines belonging to different planes, and the angle between them is 90°.

[0019] Preferably, the electric motor is connected in series to the roller by a connecting component.

[0020] Preferably, the electric slag discharging device is arranged on the lower half circumference of the shaft wall of the inclined shaft, and the inclination angle of the inclined shaft is less than 50°.

[0021] Preferably, the electric slag discharging devices are arranged at intervals from top to bottom along the inclined shaft.

[0022] Preferably, 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.

[0023] Preferably, one end of the gripper is embedded in the groove, and the other end of the gripper is supported by the inner wall of the inclined shaft.

[0024] Preferably, during the construction of the TBM tunneling machine, the electric device drives the roller to operate, realizing an automated function. Due to the rotation and vibration of the roller, the excavated material contacted by the roller is moved downward along the inclined shaft.

[0025] Preferably, the connecting component is a connecting shaft.

[0026] Preferably, the connecting component is a flexible shaft, which is used to meet the driving requirements in different axial directions by utilizing the torsion of the flexible shaft.

[0027] The method for using the electric slag discharging device in the inclined shaft TBM tunneling of a pumped-storage power plant includes the following steps 1 to 4.

[0028] In step 1, make preparations in advance. Put the electric slag discharging device and the gripper in an unactivated state, and embed the gripper in the groove.

[0029] ]>In step 2, put in the electric slag discharging device. Put the electric slag discharging device into the inclined shaft by a towing rope and arrange it at intervals.

[0030] In the third step, the electric slag discharge device is secured. The grippers are released, and the device is supported within the shaft wall by pressure.

[0031] In the fourth step, the slag is discharged. After the electric device is started, when the excavated material encounters the roller, the rotation of the roller and high-frequency vibration assist in the discharge of the slag. [Effects of the Invention]

[0032] The present invention has the following beneficial effects. The present invention's single-stage long inclined shaft TBM construction method is not limited by construction technology, reduces the number of construction tunnels and roads, and shortens the construction period. It also optimizes the placement of the water intake system, shortens its length, and reduces hydraulic losses. Under equivalent adjustment and guarantee conditions, the factory building location can be moved downwards, shortening the length of auxiliary tunnels for the factory building, shortening the length of exploration tunnels, clarifying the geological conditions of the factory building location earlier, and shortening the construction period. After excavating a pilot tunnel, expansion excavation is performed from top to bottom with the TBM, and the slag slides down due to the weight of the excavated material. An electric slag discharge device is used to assist in the sliding of the slag, and the excavated material can be processed without passing it through the TBM drilling machine. This optimizes the TBM equipment and reduces the number of devices that pass slag through the inside of the equipment. The TBM drilling machine performs expansion excavation from top to bottom, and the weight of the TBM drilling machine increases the drilling pressure of the TBM cutter head, improving drilling efficiency and reducing energy consumption. The construction technology of the present invention is simple, the construction equipment is simple, the slag removal efficiency is high, it is convenient for widespread use and application, and compared to measures that assist in slag removal by hydraulic power, it is more environmentally friendly and economical, does not require artificial slag removal, and can reduce safety risks.

[0034] Specific embodiments of the present invention will be described in more detail below with reference to the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0035] In describing the present invention, the directions or positional relationships indicated by terms such as "center," "vertical," "horizontal," "up," "down," "front," "back," "left," "right," "perpendicular," "horizontal," "ceiling," "bottom," "inside," and "outside" are directions or positional relationships based on the illustrations and are merely for the convenience and simplification of the description of the present invention. They do not explicitly or implicitly suggest that the device or component in question has a specific direction or must be configured and operated in a specific direction. Therefore, they should not be interpreted as limiting the present invention. Furthermore, the terms "first" and "second" are merely for the convenience of description and should not be interpreted as explicitly or implicitly indicating relative importance.

[0036] It should be noted that, unless otherwise explicitly defined and limited, the terms “attach,” “connect,” and “join” in this invention should be interpreted broadly. For example, they may be fixed connections, removable connections, or integral connections. They may also be mechanical or electrical connections. Furthermore, they may be direct connections, indirect connections via an intermediate medium, or internal communication between two components. Those skilled in the art will be able to interpret the specific meanings of these terms in this invention according to the specific circumstances.

[0037] Furthermore, unless otherwise specified, the term "multiple" in the description of this invention means two or more.

[0038] As shown in Figures 1 and 2, before describing the electric slag discharge device in TBM excavation of an inclined shaft, we will first describe the layout of the water intake system of the pumped-storage power plant. As shown in Figure 1, the water intake system of the pumped-storage power plant mainly consists of an upper flat water intake section, an upper inclined shaft section, a middle flat section, a lower inclined shaft section, and a lower flat section. In TBM construction, the upper flat water intake section, the upper inclined shaft section, the middle flat section, and the lower inclined shaft section are integrated into a single long inclined shaft 3. The upper part of the single long inclined shaft 3 is the upward / outlet 2, and the lower part is the lower horizontal water intake tunnel 4.

[0039] When excavating a long inclined shaft with a gentle slope using TBM construction, the excavated material is discharged by sliding the slag down due to its own weight. However, when the slope angle is relatively gentle, slag tends to accumulate, affecting the progress of construction. To solve this technical problem, the present invention provides an electric slag discharge device for TBM excavation of inclined shafts in pumped-storage power plants. This problem can be solved by the rotation and vibration of rollers. This prevents slag accumulation, ensures smooth slag discharge, and makes slag discharge safer and more environmentally friendly. Furthermore, construction using this device is simple, convenient, and easily implemented.

[0040] The electric slag discharge devices 5 are positioned around the lower half of the shaft wall of the long inclined shaft 3, spaced apart from top to bottom along the shaft. The radius of the electric slag discharge devices 5 is customized according to the radius of the long inclined shaft and is not a variable-diameter device. Further optimization later, such as adding hinge connections or extension functions, can be used to achieve a variable-diameter adjustment function. The specific structure of the electric slag discharge devices 5 is shown in Figure 1.

[0041] The electric slag discharge device 5 is supported by the shaft wall of the long inclined shaft 3 by a gripper 9, and the gripper 9 is Groove II 82 It is embedded within, and in the case of specific implementation, Groove II 82 It can protrude from the shaft and be supported by the wall of the long inclined shaft 3.

[0042] Groove I 81Inside the TBM excavator are an electric motor 6 and a roller 7. The electric motor 6 is connected in series to the roller by a connecting component 10. During TBM excavation, the electric motor 6 drives the roller 7, enabling automated operation. When the roller 7 encounters excavated material, it rotates and vibrates at high frequency, allowing the excavated material to slide down smoothly. When there is no obstacle such as excavated material, the operation of the roller 7 stops. The electric motor 6 and the roller 7 are connected by a connecting component 10. Groove I 81 It is connected to.

[0043] Specifically, as shown in Figures 1-2, in the electric slag discharge device for the TBM excavation of the inclined shaft of a pumped-storage power plant, the electric slag discharge device 5 is an arc-shaped segment , Groove I 81, and Groove II 82 This includes: The outer wall of the arc-shaped segment is supported by the inner wall of the inclined shaft by the gripper 9, and the inner wall of the arc-shaped segment has Groove I 81 They are provided at intervals. Groove I 81 An electric motor 6 and a roller 7 are installed inside.

[0044] The electric motor 6 drives the roller 7 to rotate and / or vibrate, moving the substance or material in contact with the top and sides of the roller 7 downward along the inclined shaft.

[0045] When implementing this invention, it will have the following characteristics. Regarding the arc-shaped segments and recessed tanks, the electric slag discharge device includes arc-shaped segments and recessed tanks. The outer wall of the arc-shaped segments is supported by a gripper against the inner wall of the inclined shaft, and recessed tanks are provided at intervals in the inner wall. This structural design can adapt to changes in the shape of the inclined shaft, provide support and guiding functions, and ensure the stability and reliability of the device.

[0046] Regarding the electric motor and rollers, an electric motor and rollers are installed within the recessed groove. The electric motor is used to drive the rollers to rotate or vibrate, moving the material in contact with the rollers above and on both sides downward along the inclined shaft. The axis of rotation of the rollers 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 rollers, the descent speed and direction of the material can be controlled.

[0047] Regarding the arrangement and combination, the electric slag dischargers are positioned around the lower half of the well wall of the inclined shaft, spaced apart from top to bottom along the shaft. The electric slag dischargers are formed by combining multiple arc-shaped segments, allowing the radius of the device's internal and external working surfaces to adapt to variations in the shaft's specifications. This arrangement and combination allows for adaptation to inclined shafts of various sizes and shapes, improving the device's applicability and operational efficiency.

[0048] Therefore, it has the following advantages:

[0049] Regarding the automation function, the TBM drilling machine can be automated by using an electric device to drive the rollers during construction. The rotation and vibration of the rollers cause the excavated material in contact with the rollers to move downward along the inclined shaft, eliminating the need for manual cleaning and disposal of waste, thereby improving the efficiency and safety of the drilling process.

[0050] Regarding its high adaptability, the flexible structural design and placement method of the electric slag discharge device allow it to be adapted to inclined shafts of different shapes and dimensions. The radii of the device's internal and external working surfaces can be adjusted to match changes in the inclined shaft specifications, ensuring a tight fit between the device and the shaft and reducing the risk of waste accumulation and clogging.

[0051] Regarding stability and reliability, the arc-shaped segments are supported by grippers on the inner wall of the shaft, providing stable support and guiding functions. This structural design reduces rattle and vibration of the equipment during operation, improving the stability and reliability of the equipment.

[0052] Regarding flexible adjustment, the descent speed and direction of materials can be controlled by adjusting the rotation angle of the rollers. This flexibility allows operators to adjust the equipment according to their actual needs to adapt to different types of waste and crushed stone. This improves the applicability and processing efficiency of the equipment.

[0053] Specifically, the axis of rotation of roller 7 and the axis of the inclined shaft are perpendicular to each other and belong to two different planes. This means that the axis of rotation of the roller and the axis of the inclined shaft are not located on the same plane, but rather intersect but do not overlap. This means that there is a perpendicular relationship between the axis of rotation of the roller and the axis of the inclined shaft, and that they intersect perpendicularly. This design allows the roller to move in contact with the material inside the inclined shaft in a vertical manner.

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

[0055] Specifically, the electric motor 6 is connected in series to the roller 7 by a connecting component 10. The electric motor 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 choice depends on the application needs and design requirements.

[0056] Specifically, the electric slag discharge device 5 is positioned around the lower half of the shaft wall of the inclined shaft 3, and the inclination angle of the inclined shaft 3 is less than 50°. The electric slag discharge device 5 is positioned around the lower half of the inclined shaft 3 to process the waste and crushed stone excavated from above. At the same time, the inclination angle of the inclined shaft is limited to less than 50° to ensure the stability and operational efficiency of the device.

[0057] Specifically, the electric slag discharge devices 5 are arranged at intervals from top to bottom along the inclined shaft 3. To effectively process the waste generated during excavation, the electric slag discharge devices 5 are positioned at intervals from the top to the bottom of the inclined shaft 3. This arrangement ensures that the waste is properly processed and removed as it descends.

[0058] Specifically, the electric slag discharge device 5 is composed of a combination of multiple arc-shaped segments, and the radius of the internal and external working surfaces of the electric slag discharge device 5 is adapted to the changes in the specifications of the inclined shaft 3. The electric slag discharge device 5 is composed of multiple arc-shaped segments to adapt to the changes in the specifications of the inclined shaft 3. The radii of the internal and external working surfaces of these arc-shaped segments can be adjusted to match the changes in the specifications of the inclined shaft, ensuring good compatibility between the device and the inclined shaft.

[0059] Specifically, one end of gripper 9 Groove II 82 It is embedded in the shaft, with the other end of the gripper 9 supported by the inner wall of the shaft 3. This structural design improves the stability and support capacity of the electric slag discharge device and ensures that the device maintains a fixed position during operation.

[0060] Specifically, during the operation of the TBM drilling machine, the electric motor 6 drives and operates the rollers, enabling an automated function. The rotation and vibration of the rollers 7 move the excavated material that the rollers 7 come into contact with downward along the inclined shaft. This automated function improves construction efficiency, reduces the need for manual operation, and prevents 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 bending performance, flexible shafts can operate in curved or curved transmission paths. They can adapt to non-linear and curved layouts, enabling transmission in complex geometric environments.

[0064] Regarding elasticity and flexibility, flexible shafts are typically made from flexible materials such as elastic materials, rubber, or plastic, and therefore possess a certain degree of elasticity and flexibility. This allows them to absorb vibrations, shocks, and torsional forces during the transmission process, providing a certain level of vibration damping and cushioning.

[0065] Regarding torsional capacity, flexible shafts can withstand a certain degree of torsional force and transmit torque and rotational power. They typically possess a certain degree of torsional rigidity, enabling them to transmit torque and rotational motion during transmission.

[0066] In terms of weight reduction and flexibility, flexible shafts are lighter and more flexible than rigid transmission shafts, and are easier to install and adjust. Flexible shafts can be bent and adjusted to adapt to different layouts and spatial constraints as needed for the transmission path.

[0067] Regarding vibration absorption and noise reduction, flexible shafts, due to their flexibility and elastic properties, can reduce vibration and noise within the transmission system. They absorb and disperse vibrations and shock forces from transmission components, thereby reducing noise and vibration during the transmission process.

[0068] In the structure of this embodiment, the applied flexible shaft has the following characteristics in nonlinear transmission: excellent bending performance, elasticity and flexibility, torsional capability, lightweight and flexible, and vibration absorption and noise reduction.

[0069] The method for using an electric slag discharge device in the inclined shaft TBM drilling of a pumped-storage power plant includes the following steps 1 to 4.

[0070] In the first step, preparations are made in advance. The electric slag discharge device 5 and the gripper 9 are kept in a non-activated state, and the gripper 9 is positioned to provide support in a later step. Groove II 82 It will be buried inside.

[0071] In the second step, the electric slag discharge device 5 is installed. The electric slag discharge device 5 is brought into the inclined shaft 3 by a towing rope and positioned at intervals. By appropriately positioning the devices at different locations within the inclined shaft, a slag discharge effect is achieved that compensates for the unevenness of material discharge.

[0072] In the third step, the electric slag discharge device 5 is fixed in place. The gripper 9 is released and supported within the shaft wall of the inclined shaft 3 by pressure. The purpose of this step is to ensure the stability and fixation of the electric slag discharge device and to maintain the correct position and orientation during operation.

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

[0074] As described above, the present invention has the following features. The electric slag discharge device 5 includes a gripper 9, and the gripper 9 is Groove II 82 Embedded inside, Groove I 81 An electric motor 6 and a roller 7 are installed inside, and the electric motor 6 is connected in series to the roller 7 by a connecting component 10, and the connecting component 10 is Groove I 81 It is connected to and integrates the electric slag discharge device 5.

[0075] The electric slag discharge devices 5 are positioned around the lower half of the shaft wall of the long inclined shaft 3, which has a gentle slope angle, and are spaced apart from top to bottom along the long inclined shaft 3. The radius of the electric slag discharge devices 5 is customized according to the radius of the long inclined shaft 3 and is not a variable diameter device. Later, further optimization will be performed, and a variable diameter adjustment function will be realized by adding hinge connections and extension functions.

[0076] The electric slag discharge device 5 is supported by the shaft wall of the long inclined shaft 3 by a gripper 9, and the gripper 9 is Groove II 82 It is embedded within, and in the case of specific implementation, Groove II 82 It can protrude from the shaft and be supported by the wall of the long inclined shaft 3.

[0077] During the operation of the TBM excavator, the electric motor 6 drives the roller 7, enabling automated operation. When the roller 7 encounters the excavated material, it rotates and vibrates at high frequencies, allowing the excavated material to slide smoothly down. When there is no obstacle such as excavated material, the operation of the roller 7 stops.

[0078] The method for using an electric slag discharge device in the inclined shaft TBM drilling of a pumped-storage power plant includes the following steps 1 to 4.

[0079] In the first step, prepare in advance. Set the electric slag discharge device 5 and gripper 9 to a non-activated state, and the gripper 9 Groove II 82 It will be buried inside.

[0080] In the second step, the electric slag discharge device 5 is installed. The electric slag discharge device 5 is brought into the inclined shaft 3 using a tow rope and positioned at intervals.

[0081] In the third step, the electric slag discharge device 5 is fixed in place. The gripper 9 is released and supported within the shaft wall of the inclined shaft 3 by pressure.

[0082] In the fourth step, the slag is discharged. After the electric motor 6 is started, when the excavated material encounters the roller 7, the rotation and high-frequency vibration of the roller 7 assist in the discharge of the slag.

[0083] The above description represents only preferred embodiments of the present invention. It should be made clear that those skilled in the art may make some improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered to fall within the scope of protection of the present invention.
