Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electrical component fixing devices, and in particular discloses an energy-consuming and shock-absorbing pendulum-type shock-absorbing device for a transformer substation. Background Art
[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in the power plant is a step-up substation, whose function is to step up the electric energy generated by the generator and feed it into the high-voltage power grid. The electrical equipment in the substation is divided into primary equipment and secondary equipment. Primary equipment refers to equipment that directly produces, transmits, distributes and uses electric energy. The secondary equipment of the substation refers to equipment that measures, monitors, controls and protects the operating conditions of the primary equipment and system. The energy dissipation and shock absorption equipment used in substations is a specially designed device designed to reduce damage to substation infrastructure and electrical equipment under earthquakes or other dynamic loads. These devices reduce vibration and displacement caused by earthquakes by absorbing and dissipating seismic energy, protecting key power equipment and ensuring the stable operation of the power grid.
[0003] In the patent with publication number CN206070367U, a conversion friction pendulum shock-absorbing and isolating bearing is disclosed, which relates to the field of bridge technology, including a hyperbolic body, wherein the upper and lower curved surfaces of the hyperbolic body are respectively connected with a spherical wear-resistant slide plate I and a spherical wear-resistant slide plate II, and the upper and lower sides of the hyperbolic body are respectively provided with an upper pendulum and a lower pendulum, and a flat wear-resistant slide plate is connected to the upper surface of the upper pendulum, and a flat steel plate is provided above the upper pendulum, and a steel baffle plate arranged downward is provided at the end of the flat steel plate, and a steel baffle ring for clamping the upper pendulum is provided on the lower pendulum, and the steel baffle ring is fixed to the lower pendulum via a shear pin, and an elastic body is also provided between the upper pendulum and the steel baffle plate; the bridge will not be lifted, the problem of reciprocating lifting of the bridge structure is solved, and normal operation is achieved. Under the E2 earthquake condition, there is no relative movement between the components, which solves the problem that the service life of the spherical wear-resistant plate is greatly reduced due to long-term friction; under the E2 earthquake condition, the shear pins are sheared off, and relative movement can occur between the components to form a friction pendulum motion, but this pendulum shock-absorbing device and the existing pendulum shock-absorbing devices are buried in the soil, and when an earthquake occurs, the vibration of the ground will cause the physical properties of the soil or foundation to change, causing the energy-consuming shock-absorbing pendulum shock-absorbing device to sink. The phenomenon is particularly obvious under weak foundations or unstable soil conditions, and the physical structure of the sinking device will be damaged, such as the breakage of the connector, the failure of the damper or the jamming of the pendulum body, thereby causing the shock-absorbing device to lose its original shock-absorbing ability. In severe cases, the building may even be at risk of collapse.

DETAILED DESCRIPTION
[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention. Example 1
[0037] A substation energy-absorbing and shock-absorbing pendulum-type shock-absorbing device, such as Figure 1-Figure 5 As shown, it includes a mounting plate 1, a support plate 2, a pendulum shock absorber 3, a connecting plate 4 and an insertion mechanism 5. The supporting plate 2 is clamped on the top of the mounting plate 1, and the pendulum shock absorbers 3 symmetrically distributed front and back are fixedly connected on the left and right sides of the top of the mounting plate 1. A connecting plate 4 is fixedly connected between the tops of four pendulum shock absorbers 3, and the connecting plate 4 is fixedly connected to the bottom of the substation. The insertion mechanism 5 is provided on the mounting plate 1.
[0038] like Figure 4 and Figure 5As shown, the insertion mechanism 5 for reinforcing the equipment includes a mounting frame 51, a contact rod 52, a first top plate 53, a fixing frame 54, a clamping block 55 and an elastic rope 56. The mounting frame 51 is fixedly connected to the bottom of the mounting plate 1, and the contact rod 52 is fixedly connected to the middle of the connecting plate 4. The first top plate 53 is slidably connected to the left and right sides of the mounting frame 51, and the contact rod 52 is squeezed and fitted with the first top plate 53. The mounting frame 51 is fixedly connected to the left and right sides of the mounting frame 51, and the clamping block 55 is slidably connected to the front and rear sides of the fixing frame 54. Two front and rear elastic ropes 56 are fixedly connected between the clamping block 55 and the adjacent fixing frame 54. The first top plate 53 is provided with a clamping groove corresponding to the clamping block 55, and the first top plate 53 is clamped and fitted with the clamping block 55.
[0039] like Fig.13 As shown, it also includes a connecting mechanism 9 for controlling the synchronous movement of the two first top plates 53. The connecting mechanism 9 is arranged on the installation frame 51. The connecting mechanism 9 includes a guide block 91, a second threaded rod 92 and a second nut 93. The guide blocks 91 are fixedly connected to the front and rear sides of the installation frame 51. The middle part of the guide block 91 is rotatably connected to the second threaded rod 92. The second threaded rod 92 is rotatably connected to the installation frame 51. The second nut 93 is fixedly connected to the front and rear sides of the first top plates 53. The second nut 93 is threadedly connected to the adjacent second threaded rod 92.
[0040] When people want to improve the earthquake resistance of the substation, they can first remove the support plate 2 and bury the device in the soil, and then set up the substation on the top of the pendulum shock absorber 3. When an earthquake occurs, the lower part of the pendulum shock absorber 3 and the mounting plate 1 and other components will swing back and forth with the ground, while the upper part of the pendulum shock absorber 3, the connecting plate 4 and the substation will only shake slightly, thereby providing a good shock absorbing effect for the substation. When the earthquake causes the connecting plate 4 and the contact rod 52 on the upper part of the pendulum shock absorber 3 and the mounting plate 1 and the first top plate 53 on the lower part of the pendulum shock absorber 3 to move left and right relative to each other, the contact rod 52 will contact and squeeze the first top plates 53 on both sides, so that the first top plates 53 on both sides move back to back and insert into the soil. When the contact rod 52 squeezes the first top plate 53 on one side and moves it, the second nut 93 on the first top plate 53 It will also move immediately and drive the second threaded rod 92 to rotate, so that the first top plate 53 and the second nut 93 on the other side also move away from each other, so that the first top plates 53 on both sides can be moved synchronously and inserted into the soil, thereby increasing the contact area between the shock absorbing device and the soil and strengthening the fixation of the energy-absorbing pendulum shock absorbing device in the soil. When the earthquake level is high and the relative displacement distance between the upper and lower parts of the pendulum shock absorber 3 is long, the contact rod 52 will squeeze the first top plate 53 and move it until the groove of the first top plate 53 contacts the block 55. At this time, the block 55 will move downward into the groove under the action of the elastic rope 56, so as to clamp and fix the first top plate 53, thereby limiting the movement range of the contact rod 52 and the upper part of the pendulum shock absorber 3, and avoiding the upper and lower parts of the pendulum shock absorber 3 from being separated due to the excessive relative displacement distance, thereby causing the pendulum shock absorber 3 to lose its shock absorbing effect. Example 2
[0041] On the basis of Example 1, Figure 6-Figure 8 As shown, it also includes a support mechanism 6 for reducing vibrations of the equipment in all directions. The support mechanism 6 is arranged on the mounting plate 1. The support mechanism 6 includes a first fixed block 61, a two-way telescopic rod 62, a first spring 621, an insertion rod 63 and a second spring 64. A pair of two-way telescopic rods 62 are rotatably connected to the top of the mounting plate 1. The pair of first fixed blocks 61 are fixed to the bottom of the external building. The telescopic ends of the two-way telescopic rods 62 are rotatably connected to the adjacent first fixed blocks 61. A first spring 621 is fixed between the two-way telescopic rod 62 and the first fixed block 61. A first spring 621 is fixed between the two-way telescopic rod 62 and the mounting plate 1. The left and right sides of the bottom of the mounting frame 51 are slidably connected with the insertion rods 63 symmetrically distributed front and back, and a second spring 64 is fixed between the insertion rod 63 and the mounting frame 51.
[0042] like Figure 6 As shown, the bottom end of the insertion rod 63 is provided with a tapered surface.
[0043] When an earthquake causes the substation and the first fixed block 61 to swing left and right or back and forth relative to the mounting plate 1, the bidirectional telescopic rod 62 will immediately rotate and stretch and retract back and forth, and the first spring 621 will also be stretched and compressed back and forth. At this time, the bidirectional telescopic rod 62 and the first spring 621 can buffer and reduce shock to the left and right or back and forth swinging of the substation. When an earthquake causes the substation, the mounting plate 1, the mounting frame 51 and other components to vibrate up and down relative to the insertion rod 63, the second spring 64 will be continuously stretched and compressed back and forth. At this time, the second spring 64 can reduce the up and down vibration of the substation to enhance the shock absorbing effect of the pendulum shock absorbing device.
[0044] like Figure 9-11 As shown, it also includes a spreading mechanism 7 for the secondary reinforcement equipment, which is arranged on the first top plate 53. The spreading mechanism 7 includes a second top plate 71, a first nut 72, a first threaded rod 73, a pulley 74, a flat belt 75, a servo motor 76 and a distance sensor 77. The second top plate 71 is slidably connected to the front and rear of the first top plate 53, and the first nut 72 is fixedly connected to the side where the two second top plates 71 are close to each other. The first threaded rod 73 is threadedly connected between the two first nuts 72. The servo motor 76 is fixedly connected to the inside of the first top plate 53, and the pulley 74 is fixedly connected to the middle part of the first threaded rod 73 and the output end of the servo motor 76. A flat belt 75 is wound around the two pulleys 74. A distance sensor 77 is fixedly connected to the top of the first top plate 53, and the distance sensor 77 is electrically connected to the servo motor 76.
[0045] like Fig.11 and 13 As shown, the first threaded rod 73 and the second threaded rod 92 are both bidirectional screw rods.
[0046] like Fig. 9 and Fig.10 As shown, the first top plate 53 and the second top plate 71 are both provided with inclined surfaces.
[0047] When the first top plate 53 moves to engage with the block 55, the distance sensor 77 detects that the distance to the mounting frame 51 is too short, and starts the servo motor 76 through the controller, and drives the first threaded rod 73 to rotate through the pulley 74 and the flat belt 75, so that the first nut 72 and the second top plate 71 on the front and rear sides are moved in opposite directions and inserted into the soil, thereby increasing the contact area between the shock absorbing device and the soil again, and fixing the energy-absorbing pendulum shock absorbing device in the soil for a second time, and avoiding the pendulum shock absorbing device from sinking, being damaged and losing the shock absorbing effect during an earthquake as much as possible.
[0048] like Figure 8 and Fig.12As shown, it also includes a limiting mechanism 8 for secondary shock absorption of the up and down vibrations of the equipment. The limiting mechanism 8 is arranged on the pendulum shock absorber 3. The limiting mechanism 8 includes a second fixed block 81, a connecting rod 82, a third spring 83 and a fourth spring 84. The second fixed block 81 is fixedly connected to the bottom of the pendulum shock absorber 3, and a connecting rod 82 is slidably connected between the second fixed block 81 and the insertion rod 63. The third spring 83 is fixedly connected between the connecting rod 82 and the second fixed block 81, and the fourth spring 84 is fixedly connected between the connecting rod 82 and the insertion rod 63.
[0049] When an earthquake causes the substation, the pendulum shock absorber 3, the second fixed block 81 and other components to move upward relative to the insertion rod 63, the connecting rod 82 moves immediately, and the third spring 83 and the fourth spring 84 are also compressed immediately. When an earthquake causes the substation, the pendulum shock absorber 3, the second fixed block 81 and other components to move downward relative to the insertion rod 63, the fourth spring 84 is stretched immediately. During this period, the third spring 83 and the fourth spring 84 can dampen the up and down vibration of the substation, thereby improving the damping effect of the pendulum shock absorbing equipment.
[0050] like Fig.13 and Fig.14 As shown, a stop plate 101 is also included, and the stop plate 101 is slidably connected between the pair of insertion rods 63.
[0051] When burying the equipment, the support plate 101 can be slid downward along the insertion rod 63 for a distance, and then the insertion rod 63, the support plate 101 and other components can be buried in the soil. The presence of the support plate 101 can increase the contact area between the equipment and the soil to reinforce the shock-absorbing equipment, and can make the insertion rod 63 and the installation frame 51 and other components sink as vertically as possible along the support plate 101, thereby avoiding the substation and the shock-absorbing equipment from tilting or even collapsing when sinking, causing greater losses.
[0052] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
