Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy dissipation shock absorption, and in particular to an energy dissipation shock absorption device for a transformer substation. BACKGROUND

[0002] Transformer substations are generally installed on the ground, and if an explosive or other impact event occurs around the transformer substation, the transformer substation will be damaged to some extent due to the shock. Reducing the shock can reduce the damage to the transformer substation, and the shock energy can be reduced by the structure itself. Therefore, a shock-absorbing base is generally provided at the bottom of the transformer substation.

[0003] The existing shock-absorbing base generally consists of a base support, an extrusion spring, and an extension piece. When installing the transformer substation, the shock-absorbing base is first installed on the ground, and then the transformer substation is installed above the shock-absorbing base. If the transformer substation is subjected to vibration and moves longitudinally, the transformer substation will transmit the shock to the extrusion spring and the extension piece, which will then buffer and absorb the shock to achieve the purpose of positioning the force. However, the existing shock-absorbing base uses only an extrusion spring and an extension piece to achieve the purpose of shock absorption. If the transformer substation is subjected to severe vibration and moves violently, the extrusion spring and the extension piece may not be able to withstand the shock, and the transformer substation may collide with the base support, causing damage to the transformer substation. Therefore, a kind of energy dissipation shock absorption device for transformer substation is developed, which can achieve better shock absorption purpose. SUMMARY

[0004] The present application provides an energy dissipation shock absorption device for a transformer substation, which can achieve better shock absorption purpose.

[0006] As a preferred technical scheme of the present application, the release mechanism comprises a pressing column arranged on the connecting frame, a moving frame slidingly connected to the base near the side of the connecting frame, the moving frame and the pressing column in extrusion fit, a first inclined surface arranged on the side of the moving frame near the pressing column, the first inclined surface of the moving frame and the pressing column in extrusion fit, a second inclined surface arranged on the side of the moving frame near the first inclined surface, the second inclined surface of the moving frame and the moving disc in extrusion fit, and a reset component arranged on the side of the base away from the second inclined surface for driving the moving frame to reset.

[0007] As a preferred technical scheme of the present application, the reset component comprises a supporting column arranged on the side of the base away from the second inclined surface, the supporting column and the moving frame in sliding connection, a reset spring wound on the supporting column, the left end of the reset spring fixedly connected to the moving frame, and the right end of the reset spring fixedly connected to the base.

[0008] As a preferred technical scheme of the present application, it further comprises a pushing mechanism for moving the connecting frame to the side near the moving frame, the pushing mechanism arranged on the side of the base near the supporting column.

[0009] As a preferred technical scheme of the present application, the pushing mechanism comprises a gas cylinder arranged in the base, an extrusion block fixedly connected to the bottom of the telescopic rod of the gas cylinder, the extrusion block away from the gas cylinder in extrusion fit with the top of the connecting frame, a second multi-stage telescopic elastic member arranged on the side of the extrusion block near the moving frame, a distance sensor connected to the side of the fixed disc near the moving disc, the distance sensor and the gas cylinder electrically connected through a control module, and a locking component arranged on the side of the base near the connecting frame for locking the moving frame.

[0010] As a preferred technical scheme of the present application, the locking component comprises a wedge block slidingly connected to the side of the base near the second multi-stage telescopic elastic member, an extrusion spring connected between the bottom of the wedge block and the base, a connecting plate fixedly connected to the wedge block, the top of the connecting plate in extrusion fit with the bottom of the second multi-stage telescopic elastic member, a square slot opened on the side of the bottom of the moving frame near the wedge block, and the square slot and the wedge block in clamping fit.

[0011] As a preferred technical scheme of the present application, it further comprises telescopic members, a plurality of symmetrically arranged telescopic members arranged on the bottom of the lifting platform, and a buffer plate arranged between the bottoms of the symmetrically arranged telescopic members.

[0014] As a preferred technical scheme of the present application, the sliding frame is further provided with a plurality of screw rods threadedly connected to the side of the sliding frame.

[0015] The present application has the following advantages: when the substation is subjected to vibration and longitudinal movement, the lifting platform is pushed by the lifting platform, and the lifting platform is pressed against the buffer assembly, which, in cooperation with the damping spring, can dissipate the vibration and avoid the influence of the vibration on the work of the substation.

[0016] When the substation is subjected to relatively large vibration, the longitudinal movement of the substation is also relatively large, so that the distance of the downward movement of the lifting platform is changed, and the moving disc is pressed against the second inclined surface, which pushes the moving frame to the right to release the pressing column, so that the first multi-stage telescopic elastic member drives the moving block and the air bag ball to move upward, and the air bag ball and the first multi-stage telescopic elastic member can enhance the damping of the substation.

[0017] When the air bag ball moves upward, it will hit the buffer plate, and the telescopic member and the buffer plate can eliminate the impact force of the upward movement of the air bag ball, avoiding the impact of the air bag ball on the bottom of the lifting platform and causing vibration.

[0018] When the substation is subjected to vibration, the sliding frame can be moved transversely, and the buffer spring can have a buffering and damping effect to weaken the vibration of the substation. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1: An energy-dissipating vibration damping device for substations, such as... Figures 1-9As shown, the system includes a base 11, a lifting platform 12, a fixed plate 13, shock-absorbing springs 14, a movable plate 15, a buffer assembly 16, a first multi-stage telescopic elastic element 2, a movable block 21, an airbag ball 22, a connecting frame 23, and a release assembly. The substation 1 is installed above the base 11. The lifting platform 12 is slidably connected to the base 11. Fixed plates 13 are welded to the left and right sides of the bottom of the base 11. Three shock-absorbing springs 14 are connected to the top of each fixed plate 13. A movable plate 15 is connected between the tops of the three shock-absorbing springs 14 on the left side, and also between the tops of the three shock-absorbing springs 14 on the right side. Each of the 15 is connected to a buffer assembly 16 at the top. The top of the buffer assembly 16 is connected to the bottom of the lifting platform 12. A set of first multi-stage telescopic elastic elements 2 are connected to the front and rear sides of the bottom of the base 11. Each set is provided with three first multi-stage telescopic elastic elements 2. The three first multi-stage telescopic elastic elements 2 are distributed horizontally at equal intervals. Each of the first multi-stage telescopic elastic elements 2 is connected to a moving block 21 at the top. A connecting frame 23 is welded between the moving blocks 21. Each of the moving blocks 21 is connected to an airbag ball 22 at the top. The top of the airbag ball 22 is pressed and fitted with the bottom of the lifting platform 12. A release mechanism is provided in the base 11. The release mechanism is used to release the connecting frame 23.

[0036] like Figures 5-7 As shown, the release mechanism includes a squeezing column 25, a movable frame 26, and a reset assembly. The squeezing column 25 is welded to the lower left of the connecting frame 23. The movable frame 26 is slidably connected to the lower part of the base 11. The movable frame 26 and the squeezing column 25 are squeezed together. A second inclined surface 271 is provided on the upper left of the movable frame 26. The second inclined surface 271 on the left side of the movable frame 26 is squeezed together with the movable disk 15 on the left side. A first inclined surface 27 is provided on the upper left of the movable frame 26. The first inclined surface 27 is located to the right of the second inclined surface 271. The first inclined surface 27 of the movable frame 26 is squeezed together with the squeezing column 25. A reset assembly for driving the movable frame 26 to reset is provided on the right side of the base 11. The reset assembly includes a support column 230 and a reset spring 24. The support column 230 is welded to the right side of the base 11. The support column 230 and the movable frame 26 are slidably connected. A reset spring 24 is connected between the right side of the movable frame 26 and the base 11. The reset spring 24 is wound around the support column 230.

[0037] like Figures 9-11 As shown, it also includes a pushing mechanism for pushing the connecting frame 23 downward. The pushing mechanism is located on the right side of the base 11. The pushing mechanism includes a cylinder 3, a distance sensor 301, a pressing block 31, a second multi-stage telescopic elastic element 32, and a locking assembly. The cylinder 3 is bolted to the upper right part of the base 11. The bottom of the telescopic rod of the cylinder 3 is connected to the pressing block 31. The bottom of the pressing block 31 and the top of the connecting frame 23 are pressed together. The second multi-stage telescopic elastic element 32 is provided on the right side of the bottom of the pressing block 31. The top of the fixed plate 13 is connected to the distance sensor 301. The distance sensor 301 and the cylinder 3 are electrically connected through the control module.

[0038] like Figures 9-10 As shown, the locking assembly includes a compression spring 33, a wedge block 34, and a connecting plate 35. The wedge block 34 is slidably connected to the bottom right side of the base 11. A square groove 36 is opened on the bottom right side of the movable frame 26. The square groove 36 and the wedge block 34 are engaged. The compression spring 33 is connected between the bottom of the wedge block 34 and the base 11. The connecting plate 35 is welded to the rear side of the wedge block 34. The top of the connecting plate 35 and the bottom of the second multi-stage telescopic elastic member 32 are engaged.

[0039] When installing substation 1, the base 11 is first installed underground, with the top of the base 11 flush with the ground. Then, substation 1 is placed on top of the lifting platform 12. The lifting platform 12 is supported by a fixed plate 13, shock-absorbing springs 14, a movable plate 15, and a buffer assembly 16. The lifting platform 12 supports substation 1. When substation 1 is subjected to vibration and moves downwards, the lifting platform 12 will compress the buffer assembly 16. The pressure on the buffer assembly 16 will push the movable plate 15 downwards. The shock-absorbing springs 14 will deform adaptively, and the buffer assembly 16 will also provide cushioning. Thus, through the combined action of the shock-absorbing springs 14 and the buffer assembly 16... It can absorb the vibration of substation 1, thereby weakening the vibration and preventing the vibration from affecting the operation of substation 1. If the vibration of substation 1 is very large, causing the moving plate 15 to move downward too far, when the moving plate 15 moves downward and contacts the second inclined surface 271 set on the moving frame 26, the moving plate 15 will push the moving frame 26 to the right through the second inclined surface 271. The movement of the moving frame 26 to the right will cause the return spring 24 to be compressed. Moreover, when the moving frame 26 moves to the right, the locking component can restrict the right side of the moving frame 26. In this way, after the moving plate 15 and the second inclined surface 271 are separated, the locking component can keep the moving frame 26 in the state of moving to the right.When the movable frame 26 moves to the right, it separates from the compression column 25. At this time, the first multi-stage telescopic elastic element 2, which was originally compressed, stretches. This stretching motion causes the movable block 21 to move upward, which in turn causes the airbag ball 22 to move upward. The airbag ball 22 then contacts the bottom of the lifting platform 12. Thus, the elastic force of the first multi-stage telescopic elastic element 2 and the airbag ball 22 provides a buffering force for the lifting platform 12. When the substation 1 vibrates and causes the lifting platform 12 to move downward, the first multi-stage telescopic elastic element 2 and the airbag ball 22 can further enhance the damping of the substation 1's vibration, achieving a better shock absorption effect. When the vibration of the substation 1 decreases and the downward movement distance of the movable plate 15 is relatively short, the pushing mechanism can first release the locking component of the movable frame 26. Under the action of the return spring 24, the movable frame 26 will move to the left to reset. Subsequently, the pushing mechanism can push the connecting frame 23 downward, which in turn causes the compression column to move downward. As the compression column 25 moves downward, the connecting frame 23 moves downward, causing the moving block 21 and the airbag ball 22 to move downward and reset. This causes the first multi-stage telescopic elastic element 2 to contract. When the compression column 25 contacts the first inclined surface 27, it pushes the moving frame 26 to the right via the first inclined surface 27, compressing the reset spring 24 again. When the compression column 25 moves downward below the first inclined surface 27, the reset spring 24 causes the moving frame 26 to move to the left and reset, restricting the compression column 25 and thus restricting the connecting frame 23. In summary... As stated above, when substation 1 is subjected to relatively small vibrations, the shock-absorbing spring 14 and buffer assembly 16 can buffer and dissipate the force without triggering the first multi-stage telescopic elastic element 2 and airbag ball 22 to dissipate the force. If the first multi-stage telescopic elastic element 2 and airbag ball 22 are triggered together to dissipate the force for relatively small vibrations, the buffering effect of substation 1 may not be obvious. When substation 1 is subjected to relatively large vibrations, the first multi-stage telescopic elastic element 2 and airbag ball 22 can be triggered together to buffer and dissipate the force, which can make the shock absorption effect better. When the moving disk 15 moves downward and contacts the second inclined surface 271, the moving disk 15 pushes the connecting frame 23 to move to the right through the second inclined surface 271, and the return spring 24 is compressed. When the right side of the connecting frame 23 contacts the wedge surface of the wedge block 34, the connecting frame 23 pushes the wedge block 34 downward through the wedge surface of the wedge block 34. The downward movement of the wedge block 34 causes the connecting plate 35 to move downward, and the compression spring 33 is compressed. When the connecting frame 23 continues to move to the right, the square groove 36 moves above the wedge block 34. Under the action of the compression spring 33, the wedge block 34 will move upward and reset. The upward movement and reset of the wedge block 34 will cause the connecting plate 35 to move upward and reset. In this way, by the wedge block 34 engaging the square groove 36, the wedge block 34 can lock the position of the moving frame 26 and prevent the moving frame 26 from moving to the left and resetting.When the moving disk 15 moves downward and contacts the second inclined surface 271, the distance sensor 301 detects that the distance between itself and the moving disk 15 is greater than the rated value. The distance sensor 301 then sends an electrical signal to the cylinder 3. Upon receiving the electrical signal from the distance sensor 301, the cylinder 3 will start working. The telescopic rod of the cylinder 3 will automatically extend after 10 seconds. The telescopic rod of the cylinder 3 drives the pressing block 31 to move downward. The downward movement of the pressing block 31 drives the second multi-stage telescopic elastic member 32 to move downward. The bottom of the second multi-stage telescopic elastic member 32 will first contact the connecting plate 35. Then, as the pressing block 31 continues to drive the second multi-stage telescopic elastic member 32 to move downward, the second multi-stage telescopic elastic member 32 will push the connecting plate 35 to move downward. The downward movement of the connecting plate 35 drives the wedge block 34 to move downward, and the compression spring 33 is compressed. In this way, the wedge block 34 will first separate from the square groove 36, and then the wedge block 34 releases the moving frame 26 and the return spring... 24 will cause the moving frame 26 to move to the left and reset. When the bottom of the pressing block 31 contacts the top of the connecting frame 23, it will push the connecting frame 23 to move downward. At this time, the second multi-stage telescopic elastic member 32 will remain in the state of pressing the connecting plate 35, and the second multi-stage telescopic elastic member 32 will slowly contract under pressure. The downward movement of the connecting frame 23 will cause the moving block 21 and the airbag ball 22 to move downward and reset. After the downward movement of the connecting frame 23 causes the pressing column 25 to move and reset, the telescopic rod of the cylinder 3 will automatically retract and reset. The telescopic rod of the cylinder 3 will cause the pressing block 31 to move upward and reset. The upward movement of the pressing block 31 will cause the second multi-stage telescopic elastic member 32 to move upward and reset. The second multi-stage telescopic elastic member 32 will slowly stretch and reset. When the second multi-stage telescopic elastic member 32 and the connecting plate 35 separate, under the action of the pressing spring 33, it will cause the wedge block 34 to move upward and reset. The upward movement of the wedge block 34 will cause the connecting plate 35 to move upward and reset.

[0040] Example 2: Based on Example 1, such as Figures 12-13 As shown, it also includes a buffer plate 4 and a telescopic component 42. The bottom left side, the bottom middle of the bottom of the lifting platform 12, and the bottom right side of the bottom of the lifting platform 12 are all connected to the telescopic components 42 that are symmetrically arranged in front and back. The bottom of the telescopic components 42 that are symmetrically arranged in front and back is welded with a buffer plate 4. The bottom front and back sides of the buffer plate 4 are all provided with a central groove 41, and the central groove 41 and the airbag ball 22 are squeezed together.

[0041] In the preceding text, after the movable frame 26 moves to the right to release the compression column 25, the first multi-stage telescopic elastic member 2 will drive the movable block 21 and the airbag ball 22 to move rapidly upward. When the airbag ball 22 moves rapidly upward, it will hit the bottom of the lifting platform 12. This can easily cause vibration due to the airbag ball 22 hitting the lifting platform 12, thus causing vibration in the substation 1. Therefore, to avoid the above problem, a buffer plate 4 and a telescopic member 42 are set. When the airbag ball 22 moves upward, it will hit the buffer plate 4 first. The buffer plate 4 will then move up and down adaptively, and the telescopic member 42 will also move in an adaptive telescopic motion. In this way, the telescopic member 42 and the buffer plate 4 can buffer the airbag ball 22 and prevent the airbag ball 22 from hitting the bottom of the lifting platform 12 and causing vibration.

[0042] like Figure 14 As shown, it also includes a sliding frame 5, guide rods 51 and buffer springs 52. Guide rods 51 are symmetrically fixed to the upper left and right sides of the lifting platform 12. The sliding frame 5 is slidably connected between the guide rods 51. The sliding frame 5 is threadedly connected to the four sides of the sliding frame 5. The substation 1 can be fixed to the sliding frame 5 by the screws. Buffer springs 52 are wound around the guide rods 51. One end of the buffer spring 52 is connected to the lifting platform 12 and the other end of the buffer spring 52 is connected to the sliding frame 5.

[0043] In order to enhance the vibration reduction of substation 1, a sliding frame 5, a guide rod 51, and a buffer spring 52 are provided. Substation 1 can be fixed on the sliding frame 5 by a screw. When substation 1 is subjected to vibration, substation 1 may drive the sliding frame 5 to move left and right, and the buffer spring 52 will play a role in buffering and reducing vibration.

Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
