Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically a shock-absorbing base for generators. Background Technology

[0002] Gas turbine generator sets are a new type of generator set developed to meet global environmental protection requirements and the new market environment. Natural gas generator sets are mainly divided into two types: combined cycle gas turbines and gas internal combustion engines. Gas turbines have higher power output and are mainly used in large and medium-sized power plants, while gas internal combustion engines have lower power output and are mainly used in small distributed power plants. It is a new type of green and environmentally friendly power source that replaces oil and coal-fired generator sets. In gas turbine generators, the gas burns violently, and the cylinders perform work in a specific sequence. The thrust acting on the piston is converted into a force that drives the crankshaft to rotate via the connecting rod. Utilizing the principle of electromagnetic induction, the generator outputs an induced electromotive force, which generates current through a closed load circuit. During operation, generator sets generate significant vibrations, affecting the normal operation and service life of the equipment. Therefore, it is necessary to install the generator set on a vibration-damping base.

[0003] Existing vibration damping bases for generators require multiple damping feet to be mounted on the base to dampen vibrations at various mounting points due to the large size of the generator unit. However, after prolonged operation, the buffer block on one of the damping feet may wear or be damaged, significantly reducing its damping effect and causing the generator unit to operate in an unbalanced state. Furthermore, replacing the buffer block is inconvenient. Therefore, there is an urgent need to develop a vibration damping base for generators to overcome the shortcomings in current practical applications. Summary of the Invention

The replacement port is larger than the buffer block, so that the worn or damaged buffer block can be easily removed from the replacement port on the side of the shock absorption foot. This allows for the replacement of the buffer block without affecting the supporting and shock absorption functions of other buffer blocks. The operation is simple and convenient for workers, and it is worth promoting. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0048] Please see Figures 1-5 The present invention provides a vibration damping base for a generator, comprising a base 11, wherein the base 11 is provided with a plurality of vibration damping legs 1, and each vibration damping leg 1 is equipped with a buffer block 4, and further comprising:

[0049] Replacement port 2, wherein replacement port 2 is provided on the shock-absorbing support leg 1; and

[0050] A shock-absorbing mechanism is located on the shock-absorbing support leg 1 and is detachably connected to the buffer block 4. The shock-absorbing mechanism includes a lifting component and a positioning drive component.

[0051] The lifting assembly is connected to the shock-absorbing support 1 and the buffer block 4 respectively. The positioning drive assembly is connected to the shock-absorbing support 1 and is also connected in cooperation with the lifting assembly.

[0052] Before the generator set is put into use, the base 11 is first fixed to the designated area with bolts. Then, the buffer blocks 4 on the multiple shock-absorbing feet 1 are installed on each of the generator set's base feet. The connection between the two can be made with bolts. The shock-absorbing feet 1 are in the form of square steel cylinders, and the buffer blocks 4 are located on the top of the shock-absorbing feet 1 and protrude from the top of the shock-absorbing feet 1 by a certain distance. In addition, the rest of the bottom part of the buffer block 4 is located inside the shock-absorbing feet 1 and connected to the shock-absorbing mechanism. Under the upward thrust and support of the shock-absorbing mechanism, the multiple buffer blocks 4 can provide shock absorption for the generator set during operation. When performing shock absorption work and needing to replace the buffer block 4, the positioning drive component can separate it from the lifting component. After the lifting component loses its supporting and pushing function, its gravity will cause the buffer block 4 to move downwards until it falls to be aligned with the replacement port 2. The replacement port 2 is larger than the buffer block 4 to facilitate the removal of the worn or damaged buffer block 4 from the replacement port 2 on the side of the shock absorption support 1. This allows for the replacement of the buffer block 4 without affecting the supporting and shock absorption functions of other buffer blocks 4. The operation is simple and convenient for workers, and it is worth promoting.

[0053] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The lifting assembly includes:

[0054] Support platform 3 is slidably installed inside the shock-absorbing leg 1. Rubber rings are on the side wall of the support platform 3, and the support platform 3 is also detachably connected to the buffer block 4.

[0055] A square lifting column 7 is fixedly connected to the support platform 3.

[0056] A placement slot 5 is formed on the side wall of the square lifting column 7, and a rack 6 is installed in the placement slot 5, the rack 6 being connected to the positioning drive assembly; and

[0057] The telescopic buffer unit is connected to the shock-absorbing support leg 1 and is detachably connected to the square lifting column 7.

[0058] The telescopic buffer unit includes: a mounting plate 14, which is fixedly mounted on the square lifting column 7;

[0059] The shock-absorbing air cylinder 8 is fixedly connected to the shock-absorbing support leg 1, and a piston is slidably installed inside the shock-absorbing air cylinder 8. The piston is detachably connected to the mounting plate 14.

[0060] The charging / discharging port 9 is fixedly installed on the shock-absorbing air cylinder 8 and is connected to the shock-absorbing air cylinder 8; and

[0061] A pressure display 10 is fixedly connected to the shock-absorbing air cylinder 8.

[0062] After the new buffer block 4 is reinstalled on the support platform 3, the buffer block 4 and the support platform 3 can be connected by bolts. The rubber ring on the side wall of the support platform 3 is used to buffer the lateral vibration. At this time, air is injected into the shock-absorbing cylinder 8 through the inflation / deflation port 9 by an external air pump. The air pressure display 10 can detect the gas pressure in the shock-absorbing cylinder 8 to ensure that the air pressure in the inflated shock-absorbing cylinder 8 is equal to that in other shock-absorbing cylinders 8, thereby ensuring that the position and force of the multiple buffer blocks 4 are approximately equal. Under the action of air pressure, the piston in the shock-absorbing cylinder 8 drives the square lifting column 7 and the support platform 3 to move upward, thereby driving the buffer block 4 to move upward to the base position of the generator set. At this time, the positioning drive component can position the square lifting column 7 and make the square lifting column... 7 continues to move upwards until it is approximately equal in position to other buffer blocks 4, thus ensuring the smooth operation of the generator set. Since the piston is connected to the mounting plate 14 by bolts, the square lifting column 7 can be rotated 90° while replacing the buffer block 4, so that the rack 6 located in other directions on the square lifting column 7 can contact the positioning drive assembly, thereby improving the service life of the rack 6 and preventing damage to the rack 6. Conversely, when it is necessary to replace the buffer block 4, the gas in the shock-absorbing air cylinder 8 is released through the charging and discharging port 9, and the square lifting column 7 is put into a free fall state by manually controlling the positioning drive assembly. Thus, under the action of gravity, the square lifting column 7 can move the buffer block 4 down to the replacement port 2 for easy replacement of the buffer block 4.

[0063] In one embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 5 The positioning driving component includes:

[0064] Adjustment port 2 30, which is provided on the shock-absorbing support leg 1;

[0065] Pressure rod 28 is rotatably mounted on the shock-absorbing leg 1 via support base 29, and pressure rod 28 passes through adjustment port 20 and is slidably connected to adjustment port 20;

[0066] A drive pawl 27 is located inside the shock-absorbing support leg 1, with one end of the drive pawl 27 rotatably mounted on the pressure rod 28, and the other end of the drive pawl 27 detachably connected to the rack 6; and

[0067] The positioning unit is connected to the shock-absorbing support leg 1 and is detachably connected to the rack 6.

[0068] The positioning unit includes: an adjustment port 15, which is provided on the shock-absorbing leg 1;

[0069] The positioning claw 18 is rotatably mounted on the shock-absorbing foot 1 via the support base 20, and the positioning claw 18 passes through the adjustment port 15 and is slidably connected to the adjustment port 15. The positioning claw 18 is also detachably connected to the rack 6.

[0070] Connecting rod 16, the connecting rod 16 being fixedly mounted on the positioning claw 18; and

[0071] The reset elastic plate 19 is detachably connected at one end to the shock-absorbing support leg 1, and at the other end is slidably connected to the positioning claw 18.

[0072] When the buffer block 4 moves upward under air pressure, it may not reach the designated height due to limited air pressure. At this point, a pressure rod 28, with a connecting rod 16 at its end, engages with an external long pressure rod. Through the lever principle, the long pressure rod is repeatedly lifted and lowered manually. This, combined with the action of the drive pawl 27 and the rack 6, acts like a ratchet and pawl mechanism, allowing the square lifting column 7 to move the buffer block 4 further upward. A torsion spring can be installed at the hinge between the pressure rod 28 and the support base 29, ensuring that the pressure rod 28 and drive pawl 27 remain in a fixed position when not in operation. In this position, the drive pawl 27 is positioned between the teeth of the rack 6, limiting its movement. The drive pawl 27 then drives the square lifting column 7... While moving upward, the positioning claw 18 works in conjunction with the adjustment port 15, allowing the positioning claw 18 to rotate counterclockwise by a certain angle before immediately returning to its original position. This ensures that the right end of the positioning claw 18 is always engaged between the teeth of the rack 6, similar to a ratchet pawl mechanism. The positioning claw 18 works in conjunction with the drive claw 27, which are located on opposite sides of the square lifting column 7. This prevents the upward-moving square lifting column 7 from falling back down and serves as a positioning mechanism. Furthermore, the insertion rod 16 on the positioning claw 18 allows for manual counterclockwise rotation of the positioning claw 18 when replacing the buffer block 4. This is achieved by placing an external long pressure rod on the insertion rod 16, causing the reset elastic plate 19 to bend and deform. This separates the right end of the positioning claw 18 from the rack 6, allowing the square lifting column 7 to fall freely.

[0073] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 It also includes: a plurality of detection grooves 12, each detection groove 12 being formed within the placement groove 5 and spaced apart from the teeth on the rack 6, with the depth of the plurality of detection grooves 12 increasing sequentially from top to bottom; and

[0074] Magnet 13, the number of which is equal to the number of detection grooves 12, and multiple magnets 13 are respectively installed in multiple detection grooves 12; and

[0075] A position measuring component is located on the positioning claw 18 and is detachably connected to the magnet 13.

[0076] The position measuring component includes: a movable cavity 24, which is opened on the positioning claw 18. A torque shaft 21 is rotatably installed in the movable cavity 24. One end of the torque shaft 21 passes through the positioning claw 18 and is rotatably connected to the positioning claw 18. A knob 17 is also fixedly installed on the end of the torque shaft 21.

[0077] A flexible measuring tape 23, one end of which is wound around the torque shaft 21;

[0078] A receiving groove 25 is formed at the end of the positioning claw 18, and a second magnet 26 is placed in the receiving groove 25. The second magnet 26 is fixedly connected to the other end of the flexible ruler 23, and the second magnet 26 is also detachably connected to the first magnet 13; and

[0079] The observation port 22 is located on the positioning claw 18 and is positioned directly opposite the flexible ruler 23.

[0080] During the upward movement of the square lifting column 7, manual restraint can tighten the movable cavity 24 and keep the magnet 26 in the receiving groove 25. When the buffer block 4 reaches approximately the designated height, the external force on the knob 17 is removed. Under the action of magnetic attraction, the magnet 26 will move into the corresponding detection groove 12. Since the depth of each detection groove 12 is different, the distance the magnet 26 moves when it contacts the magnet 13 is also different, thus pulling the flexible ruler 23 by different lengths. At the same time the flexible ruler 23 is pulled, the torque shaft 21 rotates. The torque shaft 21 can be equipped with a spring to keep the flexible ruler 23 taut. Thus, the operator can observe the scale of the flexible ruler 23 from the observation port 22 to ensure that the scale of the flexible ruler 23 displayed here is the same as the scale of the flexible ruler 23 displayed in other shock-absorbing feet 1. The scale of the flexible ruler 23 can be used to determine when to replace it. When buffer block 4 is in use, it rises to the designated position, thus ensuring the generator set operates in a horizontal state, improving vibration damping and extending the service life of various components. Additionally, when buffer block 4 wears down, or when the generator experiences excessive vibration during operation, the square lifting column 7 will move upwards a short distance under air pressure. At this time, due to the magnetic attraction between magnet 26 and magnet 13, magnet 26 will pull the flexible ruler 23 a short distance. Workers can infer the wear level of buffer block 4 by observing the changes in the scale of the flexible ruler 23. If the vibration amplitude of buffer block 4 is relatively large, the scale on the flexible ruler 23 located at the observation port 22 will reciprocate under the pulling force of magnet 26 and the spring on the torque shaft 21. Workers can also judge the vibration damping effect of buffer block 4 based on the frequency of the scale movement on the flexible ruler 23, facilitating timely adjustment or replacement. Further details are omitted here.
