Description

Technical Field

[0001] This invention relates to the field of pumped storage technology, specifically to a pumping device for the collection well of a pumped storage power station and its usage method. Background Technology

[0002] After the construction of a pumped storage power station, there is usually a problem of seepage in the reservoir basin. Generally, the seepage water is collected into the collection well on the side of the reservoir basin by setting up a drainage corridor at the bottom of the reservoir. As the water in the collection well increases, it is necessary to pump the collection well regularly. The conventional pumping method is to use a centrifugal pump, but this method has some disadvantages, such as: (1) Directly transported by a centrifuge, the outlet is filtered by a filter screen, but due to the lack of a limiting pumping function, when the pumping outlet sinks to the bottom, it is easy to suck in mud or sand from the collection well and clog the filter screen, which is not conducive to continuous use; (2) It lacks the function of automatically leveling the airflow, which is not conducive to the continuous and efficient operation of the device; (3) It usually needs to use electricity, gasoline or diesel to continuously supply energy, and lacks the function of auxiliary endurance. Summary of the Invention

[0004] The present invention achieves its objective by employing the following technical solution:

[0005] A pumping device for a pumped storage power station's sump well includes a mounting base, a support tray above the mounting base, an assembly shell on the outer wall of the support tray, and a photovoltaic panel on the top of the assembly shell; a centrifuge at the center of the support tray, the centrifuge being connected to a drive motor B and a drive motor A; the support tray being connected to a tee pipe, the tee pipe being connected to a rear connecting pipe, and the rear connecting pipe being connected to a floating plate; the support tray being connected to a drainer; and a venting device being provided in the support tray.

[0006] In the aforementioned pumped storage power station water collection well pumping device, the top of the mounting base is connected to the front fixing frame, the top of the front fixing frame is provided with a connecting seat, and the top of the connecting seat is provided with a bearing tray.

[0007] In the aforementioned pumped storage power station well pumping device, the centrifuge has a centrifugal shaft at its bottom, which is rotatably mounted in the middle of the bottom of the support tray via a waterproof bearing. The centrifugal shaft gear is connected to the drive motor B. The bottom of the centrifugal shaft has a drive gear, which is configured as two bevel gears with opposite directions, and a ratchet structure is provided between the two bevel gears. The upper bevel gear of the drive gear meshes with the bevel gear on the output shaft of the drive motor B, and the lower bevel gear of the drive gear meshes with the bevel gear on the driven shaft located in the connecting seat. The bevel gear on the driven shaft also meshes with the bevel gear on the output shaft of the drive motor A located in the connecting seat.

[0008] In the aforementioned pumped storage power station water collection well pumping device, the main body of the ventilation device is a cylindrical structure. The top of the cylindrical structure has a conical opening. Multiple sets of guide frames are provided inside the cylindrical structure. Guide rods are slidably arranged in the guide frames. The top of the guide rods is connected to a conical plug that matches the conical opening, and the bottom of the guide rods is connected to a float. When the float floats to the top of the assembly shell, the conical opening and the conical plug are sealed.

[0009] In the aforementioned pumped storage power station water collection well pumping device, the top of the assembly shell is provided with an extension cover, the rear part of the extension cover is covered on the conical opening, and the front part of the extension cover extends beyond the edge of the assembly shell.

[0010] In the aforementioned pumped storage power station water collection well pumping device, the transverse pipe of the tee pipe is fixedly installed in two sets of rear fixing frames, which are connected to the top of the mounting base.

[0011] In the aforementioned pumped storage power station water collection well pumping device, the bottom of the bearing tray is connected to the connecting pipe, and the connecting pipe is connected to the upper part of the connecting seat; the rear part of the drainer is connected to the connecting seat through the front group pipe, the interior of the drainer is set as a sloping structure with the rear higher than the front, and a generator impeller is rotatably installed in the middle of the drainer, and the generator impeller is connected to the generator.

[0012] In the aforementioned pumped storage power station's water collection well pumping device, the photovoltaic power generation panel and the generator are connected to the power storage device, and the power storage device is connected to the drive motor B.

[0013] In the aforementioned pumped storage power station water collection well pumping device, the rear connecting pipe is connected to a hinge seat, which is located on the top of the floating disk with a central opening, and the bottom of the floating disk is provided with a bottom support.

[0014] A method for using a pumping well pumping device for a pumped-storage power station includes installing a mounting base at the water's edge, placing a floating plate in the water source, the floating plate floating on the water surface, then starting a drive motor A with an external power supply to drive a centrifuge to rotate, the centrifuge generating conveying capacity to pump water from the water source into a middle support tray through a rear connecting pipe and a three-way pipe. During the process, a venting device vents the air from the support tray, and the water in the support tray is discharged through a drainer. When drive motor A is stopped, the energy stored by the photovoltaic power generation panel can enable drive motor B to drive the centrifuge to operate.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The device of this invention has a novel and simple structure. In use, simply install the mounting base on the water's edge, place the floating plate in the water source, and the floating plate floats on the water surface. Then, connect an external power source to start the drive motor A to drive the centrifuge to rotate. The centrifuge generates conveying capacity, drawing water from the water source through the rear connecting pipe and the three-way pipe into the middle bearing tray, and then discharging it through the drainer. Therefore, this invention is convenient to construct, has high working efficiency, and can effectively improve the efficiency of water treatment in the water collection well of pumped storage power stations, saving a lot of manpower and material resources. It has strong application value, good social benefits, and economic benefits.

[0018] 2. The floating disk proposed in this invention has a limiting extraction function. The bottom support can limit the lowest position of the floating disk to avoid sucking in mud. After the outside water enters the floating disk, it enters the space between the assembly shell and the bearing tray through the hinge seat, the rear assembly pipe and the tee pipe, then flows into the connecting seat through the connecting pipe, and then enters the drain through the front assembly pipe to be discharged without being blocked. On the other hand, the middle part of the rear assembly pipe is provided with a corrugated pipe, which, combined with the hinge rotation function of the hinge seat, makes it flexible and convenient to arrange the floating disk.

[0019] 3. This invention features a centrifugal shaft at the bottom of the centrifuge. The centrifugal shaft is rotatably mounted in the center of the bottom of the support tray via a waterproof bearing. A drive gear is located at the bottom of the centrifugal shaft. The drive gear consists of two bevel gears, one above the other, operating in opposite directions, with a ratchet mechanism between them. The upper bevel gear meshes with a bevel gear on the output shaft of the drive motor B, while the lower bevel gear meshes with a bevel gear on a driven shaft located in the connecting seat. The bevel gear on the driven shaft also meshes with a bevel gear on the output shaft of the drive motor A located in the connecting seat. This configuration includes two drive systems. Furthermore, the ratchet mechanism within the drive gear ensures that when powered by a power storage device, the drive motor B will not drive the lower bevel gear and its connecting parts via the upper bevel gear, thus reducing the load and extending the operating range.

[0020] 4. During the use of the device of the present invention, the original air cannot be discharged normally when water enters the bearing tray, resulting in a smaller flow rate. At this time, the air can be discharged through the ventilation device. When the water level rises, it drives the float to rise, and then the guide rod and the conical plug rise. The conical plug fits into the conical opening to seal the ventilation device, thereby ensuring that the pressure is normal when the water in the bearing tray increases.

[0021] 5. The present invention has an extension cover on the top of the assembly shell, and the rear part of the extension cover covers the conical opening, which effectively protects the ventilation device and prevents foreign objects from falling into the conical opening and causing blockage; and the front part of the extension cover extends beyond the edge of the assembly shell to ensure ventilation.

[0022] 6. During the use of this invention, when water flows into the drainer and moves forward, it drives the generator impeller to rotate, which in turn drives the generator to rotate and generate electricity. In addition, the photovoltaic panel generates electricity through photovoltaic power generation. The combination of these two methods can charge the power storage device. When the power supply of the external power grid is turned off and the drive motor A is stopped, the drive motor B can still be driven by the power storage device to continue operating, which greatly improves the device's endurance.

[0023] 7. The device and method provided by the present invention solve the problems of existing pumping devices lacking functions such as limited extraction, automatic airflow leveling and auxiliary driving. It can effectively improve the pumping efficiency and stability of pumped storage power stations, ensure the timely discharge of water accumulated in pumped storage power stations, and ensure the safe operation of power stations. It has good practicality, economy, energy saving and sustainable use. Attached Figure Description

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0041] Example. A pumping device for the sump well of a pumped storage power station, such as... Figure 1-9 As shown, the system includes a mounting base 1, a support tray 2 above the mounting base 1, an assembly shell 5 on the outer wall of the support tray 2, and a photovoltaic panel 502 on the top of the assembly shell 5. A centrifuge 3 is located at the center of the support tray 2, connected to a drive motor B4 and a drive motor A203. The support tray 2 is connected to a three-way pipe 501, which in turn connects to a rear assembly pipe 803, which in turn connects to a floating plate 8. The support tray 2 is also connected to a drain device 7. A ventilation device 6 is located within the support tray 2. The photovoltaic panel 502 generates electricity and stores it simultaneously for extended operation.

[0042] How to use the pumping device: Install the mounting base 1 on the water's edge, place the floating plate 8 in the water source, and let the floating plate 8 float on the water surface. Then, connect an external power source to start the drive motor A203 to drive the centrifuge 3 to rotate. The centrifuge 3 generates conveying capacity, drawing water from the water source into the middle support tray 2 through the rear connecting pipe 803 and the three-way pipe 501. During the process, the ventilation device 6 vents the air from the support tray 2, and the water in the support tray 2 is discharged through the drainer 7. When the drive motor A203 is stopped, the energy stored by the photovoltaic power generation panel 502 can drive the drive motor B4 to operate the centrifuge 3.

[0043] The three-way pipe 501 connects to the rear connecting pipe 803. When the pumping efficiency is high and the water supply efficiency of one rear connecting pipe 803 is insufficient, two rear connecting pipes 803 can be connected through the three-way pipe 501 to improve the pumping efficiency.

[0044] The top of the mounting base 1 is connected to the front fixing bracket 101, and the top of the front fixing bracket 101 is provided with a connecting seat 201, and the top of the connecting seat 201 is provided with a support tray 2. The connecting seat 201 is hollow inside, connecting the drainer 7 and the support tray 2.

[0045] The centrifuge 3 has a centrifugal shaft 301 at its bottom, which is rotatably mounted in the middle of the bottom of the support tray 2 via a waterproof bearing. The centrifugal shaft 301 is geared to the drive motor B4. The centrifugal shaft 301 has a drive gear 302 at its bottom, which is configured as two bevel gears with opposite directions, and a ratchet structure is provided between the two bevel gears. The upper bevel gear of the drive gear 302 meshes with the bevel gear on the output shaft of the drive motor B4, and the lower bevel gear of the drive gear 302 meshes with the bevel gear on the driven shaft 204 in the connecting seat 201. The bevel gear on the driven shaft 204 also meshes with the bevel gear on the output shaft of the drive motor A203 in the connecting seat 201. The ratchet structure between the two bevel gears serves the following purpose: when the drive motor A203 drives the driven shaft 204 to rotate, and the driven shaft 204, in conjunction with the bevel gear, drives the lower bevel gear of the drive gear 302 to rotate, the ratchet can drive the upper bevel gear to rotate, thereby driving the centrifugal shaft 301 to rotate; while when the drive motor B4 drives the upper bevel gear to rotate via the bevel gear, the upper bevel gear will not affect the lower bevel gear and its connected driven shaft 204 and drive motor A203.

[0046] The main body of the ventilation device 6 is a cylindrical structure. A conical opening 601 is provided at the top of the cylindrical structure. Multiple sets of guide frames 602 are provided inside the cylindrical structure. Guide rods 604 are slidably disposed within the guide frames 602. The top of the guide rods 604 is connected to a conical plug 603 that matches the conical opening 601, and the bottom of the guide rods 604 is connected to a float 605. When the float 605 rises to the top of the assembly housing 5, the conical opening 601 and the conical plug 603 are sealed. Preferably, four sets of guide frames 602 are provided. Because the original air cannot be properly discharged when water enters the carrying tray 2, resulting in a reduced flow rate, the air can pass through the ventilation device 6 and be discharged. When the water level rises, it drives the float 605 to rise, and then the guide rods 604 and the conical plug 603 rise. The conical plug 603 fits against the conical opening 601 to seal the ventilation device 6, ensuring normal pressure when the water level in the carrying tray 2 increases.

[0047] The top of the assembly housing 5 is provided with an extension cover 503, the rear of which covers the conical opening 601, and the front of which extends beyond the edge of the assembly housing 5. The extension cover 503 serves to protect the ventilation device 6, preventing foreign objects from falling into the conical opening 601 and causing blockage; and the front of the extension cover 503 extends beyond the edge of the assembly housing 5 to ensure ventilation.

[0048] The transverse tube of the tee pipe 501 is fixedly installed in two sets of rear fixing brackets 102, and the rear fixing brackets 102 are connected to the top of the mounting base 1.

[0049] The bottom of the supporting tray 2 is connected to the connecting pipe 202, and the connecting pipe 202 is connected to the upper part of the connecting seat 201. The rear part of the drainer 7 is connected to the connecting seat 201 via a front connecting pipe 703. The interior of the drainer 7 is designed with a sloping structure that is higher at the rear and lower at the front. A generator impeller 701 is rotatably mounted in the middle of the drainer 7, and the generator impeller 701 is connected to a generator 702. The generator impeller 701 is rotatably mounted in the middle of the drainer 7 with a waterproof bearing. Two sets of connecting pipes 202 are connected between the bottom of the supporting tray 2 and the two sides of the connecting seat 201. A drive motor A203 is fixedly mounted in the middle of the connecting seat 201. The drive motor A203 and the centrifugal shaft 301 are connected by a coupling. A driven shaft 204 is rotatably mounted on the rear middle side of the connecting seat 201. The use of two sets of connecting pipes 202 improves the efficiency of water discharge. When water flows into the drainer 7 and moves forward, it drives the generator impeller 701 to rotate. The generator impeller 701 drives the generator 702 to rotate and generate electricity, thereby providing the driving range. The photovoltaic power generation panel 502 stores electricity synchronously through the photovoltaic power generation function to provide the driving range.

[0050] The photovoltaic panel 502 and generator 702 are connected to a power storage device, which in turn is connected to a drive motor B4. The drive motor A203 is powered by the power grid. When the drive motor A203 has been running for a certain period of time, the power storage device is charged. At this time, the drive motor A203 is turned off, and the drive motor B4 is started. The drive motor B4, in conjunction with the bevel gear, drives the upper drive gear 302 and the centrifugal shaft 301 to rotate, utilizing the battery's endurance to work and save energy.

[0051] The rear connecting pipe 803 connects to the hinge seat 801, which is located on top of the floating disk 8 with a central opening. A bottom support 802 is located at the bottom of the floating disk 8. A corrugated pipe section is provided in the middle of the rear connecting pipe 803. Combined with the hinge rotation function of the hinge seat 801, the arrangement of the floating disk 8 is more flexible and convenient. The bottom support 802 can fix the floating disk 8 and has a limiting function, preventing the floating disk 8 from sinking to the bottom and sucking in mud or sand from the collection well, thus preventing blockage.

[0052] The floating disk 8 floats on the water surface. The drive motor A203 is started to drive the driven shaft 204 to rotate. The driven shaft 204, in conjunction with the bevel gear, drives the lower drive gear 302 and the centrifugal shaft 301 to rotate. In turn, the centrifugal shaft 301 rotates to generate conveying capacity. External water enters the floating disk 8, then passes through the hinge seat 801, the rear assembly pipe 803 and the three-way pipe 501 to enter between the assembly housing 5 and the carrier tray 2. Then, it flows through the connecting pipe 202 into the connecting seat 201, and then through the front assembly pipe 703 into the drainer 7 for discharge.

[0053] When the above scheme is implemented, the component settings are as follows: a front fixing bracket 101 is fixedly installed on the top front side of the mounting base 1; two sets of rear fixing brackets 102 are fixedly installed on the top rear side of the mounting base 1; a connecting seat 201 is fixedly installed on the bottom of the carrying tray 2, and the connecting seat 201 is fixedly installed on the top of the front fixing bracket 101; a centrifugal shaft 301 is fixedly installed on the bottom of the centrifuge 3, and the centrifugal shaft 301 is rotatably installed in the middle of the bottom of the carrying tray 2 in conjunction with a waterproof bearing; the drive motor B4 is fixedly installed on the front side of the connecting seat 201; and the assembly housing 5 is fixedly installed on the carrying tray 2. The outside of the tray 2; a three-way pipe 501 is connected to the rear side of the assembly shell 5, and the three-way pipe 501 is fixedly installed in two sets of rear fixing brackets 102; the ventilation device 6 is fixedly installed on the top front side of the assembly shell 5; a front connecting pipe 703 is connected between the rear end of the drainer 7 and the front end of the connecting seat 201; a floating plate 8, a hinge seat 801 is integrally installed on the top of the floating plate 8, a rear connecting pipe 803 is rotatably installed on one side of the hinge seat 801 in conjunction with a waterproof bearing, and the other end of the rear connecting pipe 803 is rotatably installed on one side of the three-way pipe 501 in conjunction with a waterproof bearing.

[0054] The detailed working principle and usage of the above device are as follows:

[0055] Install the mounting base 1 on the water's edge, then place the floating plate 8 in the water source. Use the bottom bracket 802 for fixation and limiting to prevent the floating plate 8 from sinking to the bottom and sucking in mud or sand from the collection well, causing blockage. The floating plate 8 floats on the water surface. Then, start the drive motor A203 connected to the external power grid to drive the driven shaft 204 to rotate. The driven shaft 204, in conjunction with the bevel gear, drives the lower drive gear 302 and the centrifugal shaft 301 to rotate. In turn, the centrifugal shaft 301 rotates to generate conveying capacity. Using the rotation of the centrifuge 3, external water enters the floating plate 8, then passes through the hinge seat 801, the rear connecting pipe 803, and the three-way pipe 501 into the assembly housing 5 and the carrying tray 2. Then, it flows through the connecting pipe 202 into the connecting seat 201, and then through the front connecting pipe 703 into the drain 7 for discharge.

[0056] When water enters the carrying tray 2, the original air cannot be discharged normally, resulting in a smaller flow rate. At this time, the air can be discharged through the ventilation device 6. When the water level rises, it drives the float 605 to rise, and then the guide rod 604 and the conical plug 603 rise. The conical plug 603 fits against the conical opening 601 to seal the ventilation device 6, ensuring that the pressure is normal when the water in the carrying tray 2 increases.

[0057] When water flows into the drainer 7, it flows forward, driving the generator impeller 701 to rotate. The generator impeller 701 drives the generator 702 to rotate and generate electricity, charging the power storage and thus providing range. At the same time, the photovoltaic panel 502 also stores energy to improve range through photovoltaic power generation.

[0058] When the drive motor A203 runs for a certain period of time, the power supply is charged. At this time, the drive motor A203 is turned off and the drive motor B4 is started. The drive motor B4, together with the bevel gear, drives the upper drive gear 302 and the centrifugal shaft 301 to rotate, and works by utilizing the endurance capacity to save energy.

[0059] This invention relates to circuits, electronic components, and modules, all of which are existing technologies and can be fully implemented by those skilled in the art. The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
