Description

Technical Field

[0001] The invention relates to a shock-absorbing and tide-reducing structure for a pumped-storage unit, and belongs to the technical field of water conservancy and hydropower underground plant construction. Background Art

[0002] The bottom of the pumped storage unit is usually in direct contact with the ground, or a pad is simply added under the tripod to prevent the machine from crushing the ground. For machines that generate strong vibrations during operation, simple vibration-damping pads will not play any substantial role.

[0003] To this end, the Chinese patent document with publication number CN107339368A discloses a noise reduction and shock absorption device for a pumped storage unit. The elastic support arm, support spring and elastic support ball together form a support plate support structure, so that the pumped storage unit is effectively and stably supported. At the same time, the vibration of the pumped storage unit is absorbed by the deformation of the elastic support arm, support spring and elastic support ball. By setting a stabilizing spring, inertial vibration can be effectively reduced and resonance can be avoided, so that the noise generated by the pumped storage unit is less. In addition, the blower blows air into the shell through the silencer hole, and a corrugated plate is arranged in the silencer hole. The sound waves in the shell are emitted through the corrugated plate, and the sound waves in the shell are discharged upward through the exhaust channel with the air flow, thereby avoiding the spread of noise around.

[0004] However, the device has the following shortcomings:

[0005] First, the pumped-storage unit is installed in the shell through multiple supporting units. The stability of the supporting units is poor, and the weight distribution of the pumped-storage unit is uneven, which causes the pumped-storage unit to tilt easily after installation, affecting the normal operation of the unit.

[0006] Second, condensation water easily accumulates at the bottom of the pumped-storage unit installed in the underground powerhouse of water conservancy and hydropower, causing the pumped-storage unit to rust easily and shorten its service life. Summary of the invention

DETAILED DESCRIPTION

[0038] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0039] like Figures 1 to 9As shown, a pumped storage unit shock absorption and tide reduction structure of the present invention comprises an underground powerhouse 1 and a tide reduction component, a support 2 is installed on the bottom plate of the underground powerhouse 1, two rows of shock absorption support mechanisms are installed side by side on the support 2, one end of the tide reduction component extends into the support 2, a plurality of ventilation slots 15 are provided on the top of the support 2 to communicate with the tide reduction component, and the plurality of ventilation slots 15 are located between the two rows of shock absorption support mechanisms. Figure 2 As shown, when in use, the pumped-storage unit is supported by the left and right rows of vibration-damping support mechanisms, and the support stability is good, ensuring the safe and normal operation of the pumped-storage unit. Air is blown to the bottom of the pumped-storage unit through the dehumidification component to keep the bottom of the pumped-storage unit dry and avoid rust, which helps to extend the service life of the pumped-storage unit.

[0040] The vibration reduction support mechanism includes a vertical vibration reduction component 3, a horizontal vibration reduction component and a fixed block 5. A support plate 4 is installed on the upper end of the vertical vibration reduction component 3, and a T-shaped slider 9 is installed on the lower end to be slidably connected with the support 2. The fixed block 5 is installed on the support 2 and is located outside the two rows of vibration reduction support mechanisms. One end of the horizontal vibration reduction component is connected to the vertical vibration reduction component 3, and the other end is connected to the fixed block 5. When in use, a T-shaped slide groove is provided on the support 2 to be slidably connected with the T-shaped slider 9. The pumped storage unit is vibration-reduced in the vertical direction by the vertical vibration reduction component 3, and the pumped storage unit is vibration-reduced in the horizontal direction by the horizontal vibration reduction component, and the vibration reduction effect is good.

[0041] The vertical vibration reduction assembly 3 includes a support tube A301 and a column A300. The support tube A301 is fixedly mounted on the T-shaped slider 9. The upper end of the column A300 is mounted with a support plate 4, and the lower end is mounted with a limit block A. The column A300 and the limit block A are both slidably connected to the support tube A301. The limit block A is located in the support tube A301 and is connected to the T-shaped slider 9 through a vibration reduction spring A302.

[0042] An end of the support plate 4 close to the fixed block 5 is inclined upward relative to an end away from the fixed block 5;

[0043] The horizontal vibration reduction assembly includes a slide bar 7 and a plurality of vibration reduction springs B6. One end of the slide bar 7 is fixedly connected to the support tube A301, and the other end passes through the fixed block 5. One end of the vibration reduction spring B6 is connected to the support tube A301, and the other end is connected to the fixed block 5. Figure 2As shown, the end of the support plate 4 close to the fixed block 5 is inclined upward relative to the end far away from the fixed block 5. During the operation of the pumped-storage unit, the pumped-storage unit is firstly damped in the vertical direction by the damping spring A302. At the same time, under the action of vibration, the support plate 4, the vertical damping assembly 3 and the T-shaped slider 9 will move to the left or right along the T-shaped slide groove as a whole, so that the damping spring B6 on one side of the pumped-storage unit is compressed and the damping spring B6 on the other side is stretched, so that the pumped-storage unit is damped in the horizontal direction by the damping spring B6, and the damping effect is good.

[0044] A friction cylinder 8 is installed on the side of the fixed block 5 away from the vertical vibration reduction assembly 3, and multiple flexible friction plates B are installed in the friction cylinder 8. The slide bar 7 is located on the inner side of the friction cylinder 8, and multiple flexible friction plates A are installed on the slide bar 7. When in use, the flexible friction plates A and the flexible friction plates B rub ​​against each other to hinder the movement of the slide bar 7, which has a certain vibration reduction effect on the vibration reduction support mechanism and the pumped storage unit in the horizontal direction.

[0045] The structure also includes an annular NdFeB magnet 10, a fixed plate 11, an extrusion plate 13 and a heating wire 16. The annular NdFeB magnet 10 is mounted on the end of the friction cylinder 8 away from the fixed block 5, and the slide bar 7 is located on the inner side of the annular NdFeB magnet 10. The fixed plate 11 is mounted on the support 2. A plurality of sliding rods 14 are mounted on the extrusion plate 13. The plurality of sliding rods 14 penetrate the fixed plate 11 and are slidably connected to the fixed plate 11. A compression spring A12 is mounted on the sliding rod 14 between the extrusion plate 13 and the fixed plate 11. The heating wire 16 is mounted in the ventilation slot 15. The two ends of the heating wire 16 are electrically connected to the two ends of the slide bar 7 one by one. The slide bar 7 is made of a copper rod. Figure 6 As shown, the slide bar 7 and the heating wire 16 form a closed loop. When the slide bar 7 moves to the right to cut the magnetic flux lines formed by the annular NdFeB magnet 10, an induced current will be generated in the slide bar 7, causing the heating wire 16 to work and generate heat. When the wind formed by the centrifugal fan 18 blows through the heating wire 16, hot wind will be formed, and then blow to the bottom of the pumped storage unit, thereby improving the drying effect and drying speed of the bottom of the pumped storage unit. At the same time, the Ampere force will prevent the slide bar 7 from continuing to move to the right, and it also has a certain vibration reduction effect on the vibration reduction support mechanism and the pumped storage unit in the horizontal direction. When the slide bar 7 continues to move to the right and begins to contact the extrusion plate 13, the compression spring A12 is gradually compressed, thereby reducing the vibration of the vibration reduction support mechanism and the pumped storage unit in the horizontal direction through the compression spring A12.

[0046] The dehumidification assembly includes a vent pipe 17 and a centrifugal fan 18, and the air outlet of the centrifugal fan 18 is connected to one end of the vent pipe 17. When in use, the wind generated by the centrifugal fan 18 passes through the vent pipe 17 and the ventilation slot 15 in sequence, and then blows to the bottom of the pumped storage unit to accelerate the drying speed of the bottom of the pumped storage unit.

[0047] The structure further comprises a condensate cleaning mechanism, which is mounted on the support 2 and is located between two rows of vibration-damping support mechanisms.

[0048] The condensed water cleaning mechanism includes two water storage boxes 28, and a driving component 20 and a cleaning component located between the two water storage boxes 28. The driving component 20 is installed on the support 2, and the cleaning component is installed on the driving component 20 through the elastic support 22, and can make reciprocating linear motion under the drive of the driving component 20. The bottom of the cleaning component is connected to the two water storage boxes 28 through the water guide pipe group. When in use, the cleaning component is driven by the driving component 20 to make reciprocating linear motion, and the condensed water at the bottom of the pumped storage unit is scraped off by the cleaning component, which greatly speeds up the drying speed of the bottom of the pumped storage unit, and the condensed water entering the cleaning component is drained into the water storage box 28 through the water guide pipe group.

[0049] The driving assembly 20 is a linear module, and both ends of the driving assembly 20 are connected to the support 2 through a supporting box 19 .

[0050] The cleaning component is installed on the module slider 21 of the linear module through an elastic support 22. The elastic support 22 includes a support tube B220 and a column B221. The support tube B220 is installed on the module slider 21. One end of the column B221 is connected to the cleaning component, and the other end is installed with a limit block B that is slidably connected to the inner wall of the support tube B220, and the limit block B is connected to the bottom of the support tube B220 through a compression spring B222. When in use, the bottom of the pumped storage unit is not flat. The structural design of the elastic support 22 leaves space for the cleaning component to be lifted and lowered in the vertical direction. At the same time, the cleaning component always keeps in contact with the bottom of the pumped storage unit under the lifting action of the compression spring B222, so as to ensure the cleaning component's effect of scraping away the condensed water at the bottom of the pumped storage unit.

[0051] The water guide pipe group includes a guide pipe 27, and a telescopic section is provided in the middle of the guide pipe 27 to adapt to the reciprocating linear motion of the cleaning component.

[0052] The cleaning assembly includes a support plate 23 and a hemispherical elastic sleeve 24. A funnel-shaped elastic sheet 26 is installed on the top of the support plate 23. A guide groove 29 is processed on the top of the support plate 23 at a position corresponding to the water inlet of the water guide pipe group. The hemispherical elastic sleeve 24 is installed on the support plate 23 and is located on the inner side of the funnel-shaped elastic sheet 26. A plurality of water-permeable holes and a plurality of wiper blocks 25 are processed on the hemispherical elastic sleeve 24. A hemispherical sponge block 31 is installed on the inner side of the hemispherical elastic sleeve 24 on the support plate 23. An extrusion block 30 is provided on the support plate 23 on the inner side of the hemispherical sponge block 31 and protrudes upward, and the lower part of the extrusion block 30 is connected to the guide groove 29. When in use, the funnel-shaped elastic sheet 26 catches and collects water drops that fall around the hemispherical elastic sleeve 24; when the hemispherical sponge block 31 is squeezed, the water inside the hemispherical elastic sleeve 24 will flow out of the hemispherical elastic sleeve 24 through the water-permeable holes, and the setting of the funnel-shaped elastic sheet 26 can prevent the water outside the hemispherical elastic sleeve 24 from flowing around on the support plate 23. When the cleaning assembly contacts the bottom of the pumped-storage unit, the scraper block 25 scrapes off the condensed water at the bottom of the pumped-storage unit, and the condensed water enters the hemispherical elastic sleeve 24 through the water-permeable holes, and is then absorbed by the hemispherical sponge block 31. When the hemispherical elastic sleeve 24 and the bottom of the pumped-storage unit are squeezed against each other, the hemispherical sponge block 31 will squeeze against the hemispherical elastic sleeve 24 and the squeezing block 30, thereby squeezing out the water absorbed by the hemispherical sponge block 31, and the squeezed water enters the guide groove 29 and flows into the water storage box 28 through the guide pipe 27.

[0053] The pumped storage unit shock absorption and tide reduction structure of the present invention has the following working principle:

[0054] 1. Shock absorption:

[0055] like Figure 2 As shown, one end of the pumped storage unit is fixedly mounted on the support plate 4 of the left row vibration reduction support mechanism, and the other end is fixedly mounted on the support plate 4 of the right row vibration reduction support mechanism. During operation, the pumped storage unit will continue to vibrate, and drive the support plate 4 and the column A300 to vibrate, causing the vibration reduction spring A302 to be compressed from time to time and to recover its deformation and elongation from time to time, thereby reducing the vibration of the column A300, the support plate 4 and the pumped storage unit in the vertical direction through the vibration reduction spring A302.

[0056] Since the support plate 4 is arranged obliquely, under the vibration of the pumped-storage unit, the pumped-storage unit and the vibration-damping support mechanism will move left or right along the T-shaped slide groove as a whole, and the vibration-damping spring B6 on one side of the pumped-storage unit will be compressed, thereby performing a vibration reduction on the pumped-storage unit in the horizontal direction through the vibration-damping spring B6; at the same time, the flexible friction plate B in the friction cylinder 8 will rub against the flexible friction plate A on the slide bar 7 to prevent the slide bar 7 from continuing to move, thereby horizontally damping the pumped-storage unit. Secondary vibration reduction is performed; when the pumped-storage unit continues to move in the same direction, the slide bar 7 will cut the magnetic flux lines formed by the annular NdFeB magnet 10, and an induced current will be generated in the slide bar 7. The formed Ampere force will hinder the slide bar 7 from continuing to move, thereby performing third vibration reduction on the pumped-storage unit in the horizontal direction; when the pumped-storage unit further moves in the same direction, the slide bar 7 contacts the extrusion plate 13, and the compression spring A12 is gradually compressed, thereby performing fourth vibration reduction on the pumped-storage unit in the horizontal direction through the compression spring A12.

[0057] 2. Tide Drop

[0058] First, the wind generated after the centrifugal fan 18 is started passes through the ventilation pipe 17 and the ventilation slot 15 and blows toward the bottom of the pumped-storage unit to accelerate the drying speed of the bottom of the pumped-storage unit.

[0059] Secondly, when an induced current passes through the closed loop formed by the slide bar 7 and the heating wire 16, the heating wire 16 generates heat and heats the wind flowing through the ventilation slot 15, so as to blow the bottom of the pumped-storage unit with hot wind to accelerate the drying speed of the bottom of the pumped-storage unit.

[0060] Again, the cleaning component is driven to perform reciprocating linear motion by the linear module, the cleaning component contacts the bottom of the pumped-storage unit, and cleans and scrapes off the condensed water at the bottom of the pumped-storage unit to accelerate the drying speed of the bottom of the pumped-storage unit.

[0061] The above measures can remove condensed water at the bottom of the pumped-storage unit, keep the bottom of the pumped-storage unit dry, avoid rust on the bottom of the pumped-storage unit, and help extend its service life.

[0062] The pumped storage unit shock absorption and tide reduction structure provided by the present invention has the following beneficial effects:

[0063] 1. The pumped storage unit is supported by the left and right rows of vibration reduction support mechanisms, which has good support stability and ensures the safe and normal operation of the pumped storage unit.

[0064] 2. The pumped storage unit is subjected to vibration reduction in the vertical direction by the vibration reduction spring A302; the pumped storage unit is subjected to vibration reduction once in the horizontal direction by the vibration reduction spring B6, the pumped storage unit is subjected to vibration reduction twice in the horizontal direction by the flexible friction plate B in the friction cylinder 8, the pumped storage unit is subjected to vibration reduction three times in the horizontal direction by the annular NdFeB magnet 10, and the pumped storage unit is subjected to vibration reduction four times in the horizontal direction by the compression spring A12, and the vibration reduction effect is good.

[0065] 3. The vibration reduction spring A302, the vibration reduction spring B6, the flexible friction plate B and the annular NdFeB magnet 10 in the left and right rows of vibration reduction support mechanisms simultaneously reduce vibration of the pumped storage unit, and the vibration reduction effect is good.

[0066] 4. First, the centrifugal fan 18 provides wind to blow the bottom of the pumped storage unit to speed up the drying speed of the condensed water at the bottom of the pumped storage unit; second, when the induced current flows through the heating wire 16, the heating wire 16 works to generate heat to increase the wind temperature, which helps to speed up the drying speed of the condensed water at the bottom of the pumped storage unit; third, the cleaning component that performs reciprocating linear motion scrapes off the condensed water, which greatly improves the drying speed of the bottom of the pumped storage unit. In this way, the bottom of the pumped storage unit is kept dry, the bottom of the pumped storage unit is prevented from rusting, and its service life is extended.
