Description

Technical Field

[0001] The present invention relates to the field of transformer shock absorption, and particularly to a transformer noise shock absorption device. Background Art

[0002] A transformer is a static electrical device used to change the voltage level of alternating current. It is an essential part of the power system. When a transformer is operating, it will generate a large amount of noise, which is likely to affect the sleep of nearby residents. Therefore, when installing a transformer, a shock absorption device is used and installed together with the transformer, so that the noise emitted by the transformer can be silenced through shock absorption, thereby reducing the volume of the noise.

[0003] The existing transformer noise shock absorption devices usually consist of an upper plate, a lower plate, and shock absorbers. The shock absorbers are arranged on the lower plate, the upper plate is arranged above the shock absorbers, and the transformer is installed on the upper plate. When the transformer emits noise and generates vibrations, the shock absorbers can perform shock absorption and noise reduction. Since the sizes and specifications of transformers on the market are not uniform, small transformers are relatively light in weight, and the vibrations generated by their noise are relatively small. On the contrary, large transformers are heavier in weight, and the vibrations generated by their noise are relatively large. Therefore, the shock absorption elasticity of the shock absorbers used for different specifications of transformers needs to be adjusted. However, the existing shock absorption devices cannot adjust the shock absorption elasticity of the shock absorbers and can only use different shock absorption devices according to different specifications of transformers, which is extremely inconvenient. Therefore, a transformer noise shock absorption device is now designed, which can facilitate the fixing and disassembly of the shock absorbers and can adjust the intensity of the shock absorption elasticity by adjusting the number of shock absorbers.

[0008] Furthermore, it also includes moving blocks. The moving blocks are respectively slidably connected to the lower plate. There are two groups of front and rear moving blocks, and each group has four moving blocks. Pull handles are connected to the outer sides of the moving blocks.

[0009] Furthermore, it also includes wedge-shaped blocks three. The wedge-shaped blocks three are fixedly connected to the inner sides of the moving blocks.

By controlling the telescopic rod of the cylinder to contract, the present invention can drive the lower pressing plate to press down and move the movable clamping plate, so that the movable clamping plate automatically snaps into the clamping groove, which facilitates the installation of the shock absorber. Conversely, when the lower pressing plate moves upward, the movable clamping plate will automatically move away from the clamping groove, which also facilitates the disassembly of the shock absorber. Moreover, different numbers of shock absorbers can be selected according to the weight of the transformer for installation, and shock absorbers with corresponding elastic forces are used for better sound insulation effect on the transformer.

[0015] 2. When the lower pressing plate moves upward and contacts the lifting plate, the present invention can automatically lift the pressing plate to press the roller, driving the first connecting rod and the second connecting rod to rotate from the " V " shape into the "one" shape. In this way, the pushing plate can be automatically pushed to move outward, and the pushing plate can push all the shock absorbers out, thus facilitating the purpose of pushing out all the shock absorbers.

[0016] 3. When the movable clamping plate moves downward to drive the wedge block two to move downward and squeeze the wedge block one, the wedge block one is released. In this way, the wedge block one can lock the wedge block two, which can prevent the movable clamping plate from moving upward to unlock the shock absorber. Then, when people add shock absorbers, it can prevent the displacement of other shock absorbers and increase the workload. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: A transformer noise damping device, as Figures 1 - 4As shown in the figure, it includes a lower plate 2. Four tracks 201 are provided on both the front and rear sides of the top of the lower plate 2. A shock absorber 3 is slidably connected to each of the tracks 201. The shock absorber 3 is composed of a shock absorber base 301, a shock absorber sleeve 302, a shock absorber spring 303 and a shock absorber column 304. The shock absorber bases 301 are respectively slidably connected to the tracks 201. Shock absorber sleeves 302 are provided on the tops of the shock absorber bases 301. Shock absorber columns 304 are slidably connected inside the shock absorber sleeves 302. Shock absorber springs 303 are connected between the tops of the shock absorber columns 304 and the shock absorber sleeves 302. The tops of the shock absorber columns 304 are connected to an upper plate 4 by bolts. Its characteristics are: Movable clamping plates 5 are respectively slidably connected to the shock absorber sleeves 302. Symmetrically arranged protrusions are provided at the bottoms of the movable clamping plates 5. Four groups of card slots 6 are provided on both the front and rear sides of the top of the lower plate 2. Two card slots 6 are provided in each group. The card slots 6 and the protrusions are in clamping fit. Return springs 7 are connected between the bottoms of the movable clamping plates 5 and the shock absorber bases 301. A pressing mechanism for pressing down the movable clamping plates 5 is provided on the top of the lower plate 2; The pressing mechanism includes a cylinder 9. The cylinder 9 is fixed in the middle of the top of the lower plate 2. The top of the telescopic rod of the cylinder 9 is fixedly connected to a lower pressing plate 8. The bottom of the lower pressing plate 8 is in extrusion fit with the movable clamping plate 5.

[0029] As Figures 4 - 5 shown in the figure, it further includes guide posts 11. The guide posts 11 symmetrically arranged on the left and right are fixedly connected to the top of the lower plate 2. Two push plates 12 for pushing out the shock absorber bases 301 are slidably connected between the two guide posts 11 on the left and right. The two push plates 12 are symmetrically arranged in the front and rear. The push plates 12 are in extrusion fit with the shock absorber bases 301. The push plates 12 are slidably connected to the lower plate 2. Tensile springs 13 are connected between the left and right sides of the push plates 12 and the lower plate 2. A pushing assembly for pushing the push plates 12 is provided on the lower plate 2; The pushing assembly includes a pushing frame 15. The pushing frame 15 is slidably connected to the lower plate 2. The upper part of the pushing frame 15 passes through the lower pressing plate 8. A lifting plate 14 is fixedly connected to the top surface of the pushing frame 15. The lower pressing plate 8 is in extrusion fit with the lifting plate 14. Extrusion plates 16 are welded on both the left and right sides of the pushing frame 15. Fixed blocks 170 are connected to both the left and right sides of the top of the lower plate 2. Second connecting rods 18 are rotatably connected to the front and rear sides of the fixed blocks 170. First connecting rods 17 are rotatably connected to both the left and right sides of the lower plate 2. The first connecting rods 17 and the adjacent second connecting rods 18 are connected by a rotating shaft. A roller 19 is connected to the rotating shaft. The roller 19 is in extrusion fit with the extrusion plate 16.

[0030] When using this noise damping device for the transformer 1, different numbers of shock absorbers 3 can be selected according to the specifications of the transformer 1. If four shock absorbers 3 are selected, the four shock absorbers 3 can be respectively slid into the two leftmost and two rightmost tracks 201. After placing the shock absorbers 3, the telescopic rod of the cylinder 9 can be controlled to shorten. The shortening of the telescopic rod of the cylinder 9 drives the lower pressing plate 8 to move downward. When the lower pressing plate 8 moves downward and contacts the moving clamping plate 5, the moving clamping plate 5 will be squeezed downward, the return spring 7 is compressed, and the protrusion of the moving clamping plate 5 will automatically snap into the clamping groove 6. In this way, the shock absorber 3 can be positioned by the moving clamping plate 5 snapping into the clamping groove 6. By pressing down the lower pressing plate 8, the moving clamping plates 5 on the four shock absorbers 3 can be snapped into the clamping groove 6 together, so that the shock absorbers 3 can be installed more quickly and conveniently. Subsequently, the upper plate 4 can be installed between the tops of the shock-absorbing columns 304 by conventional bolts and nuts. If the number of shock absorbers 3 needs to be increased or decreased, the upper plate 4 can be removed first. Subsequently, the telescopic rod of the cylinder 9 is controlled to extend to drive the lower pressing plate 8 to move upward to reset and release the moving clamping plate 5. The moving clamping plate 5 will move upward and reset under the action of the return spring 7. In this way, the shock absorber 3 can be released, and then it is convenient for people to take out the shock absorber 3 or add a shock absorber 3. If people need to remove all the shock absorbers 3 for maintenance, the telescopic rod of the cylinder 9 can be controlled to extend. The continuous extension of the telescopic rod of the cylinder 9 drives the lower pressing plate 8 to move upward. When the lower pressing plate 8 moves upward and fits with the lifting plate 14, the lifting plate 14 will be pushed upward. The upward movement of the lifting plate 14 drives the pushing frame 15 to move upward. The upward movement of the pushing frame 15 drives the pressing plate 16 to move upward. When the pressing plate 16 moves upward and contacts the roller 19, the roller 19 will be pushed upward. At this time, the first connecting rod 17 and the second connecting rod 18 respectively rotate from the " V " shape to the "one" shape, and the first connecting rod 17 will automatically push the pushing plate 12 outward. The tension spring 13 is stretched. The outward movement of the pushing plate 12 will push all the shock-absorbing bases 301 outward. In this way, all the shock absorbers 3 can be automatically pushed out, saving the effort of people manually taking out the shock absorbers 3 one by one, and making it more convenient to use. After taking out, the telescopic rod of the cylinder 9 can be controlled to contract to the initial state, driving the lower pressing plate 8 to move downward to reset. Then, the lifting plate 14 and the pushing frame 15 will move downward to reset due to their own gravity, and under the action of the tension spring 13, drive the pushing plate 12 to move inward to reset. The first connecting rod 17 and the second connecting rod 18 respectively rotate from the "one" shape to the "V" shape.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figures 6 - 7As shown in the figure, it further includes a moving block 20. The moving block 20 is respectively connected to the lower plate 2 in a sliding manner. There are two groups of moving blocks 20 arranged front and back, with four moving blocks 20 in each group. Pull handles are fixedly connected to the outer sides of the moving blocks 20. Wedge-shaped blocks one 21 are connected to the left and right sides of the top of the moving block 20. Wedge-shaped blocks two 22 are fixedly connected to the protruding positions of the moving clamping plates 5. The wedge-shaped block two 22 and the wedge-shaped block one 21 are in extrusion fit. Clamping springs 23 are connected between the sides of the moving blocks 20 close to each other and the lower plate 2.

[0032] As described above, when people need to add the shock absorber 3, the air cylinder 9 needs to be used to control the upward movement of the lower pressing plate 8 to release all the moving clamping plates 5, so that all the shock absorbers 3 are unlocked. If people accidentally touch other shock absorbers 3 already installed on the lower plate 2 when adding the shock absorber 3, it is easy to cause displacement of other shock absorbers 3. Then, when people add a new shock absorber 3, they need to adjust the positions of the other displaced shock absorbers 3, which will increase people's labor. Therefore, to avoid the above problems, the following solution is adopted. When the moving clamping plate 5 moves downward, it will drive the wedge-shaped block two 22 to move downward. When the wedge-shaped surface of the wedge-shaped block two 22 moves downward and contacts the wedge-shaped surface of the wedge-shaped block one 21, it will push the wedge-shaped block one 21 to move outward. The wedge-shaped block one 21 drives the moving block 20 to move outward, and the clamping spring 23 is stretched. When the wedge-shaped block two 22 moves downward to the lower side of the wedge-shaped block one 21, the clamping spring 23 drives the moving block 20 and the wedge-shaped block one 21 to move inward and reset. In this way, the wedge-shaped block one 21 can lock the wedge-shaped block two 22, so as to achieve the purpose of locking the shock absorber 3. In this way, when the lower pressing plate 8 moves upward to release the moving clamping plate 5, the wedge-shaped block one 21 remains in the locked state of the wedge-shaped block two 22, which can prevent the moving clamping plate 5 from moving upward to unlock the shock absorber 3. Then, when people add the shock absorber 3, they can prevent the displacement of other shock absorbers 3 and increase the workload.

[0033] As Figure 7 As shown in the figure, it further includes wedge-shaped blocks three 24. The wedge-shaped blocks three 24 are fixedly connected to the inner sides of the moving blocks 20. Slopes 25 are arranged on the front and back sides of the upper part of the pushing frame 15. The slopes 25 and the wedge-shaped blocks three 24 are in extrusion fit respectively.

[0034] During the upward movement of the lifting plate 14 that drives the pushing frame 15 and the pressing plate 16 to move upward, since there is a certain distance between the pressing plate 16 and the roller 19, when the pushing frame 15 moves upward, it will drive the inclined surface 25 to move upward. When the inclined surface 25 contacts the wedge surface of the third wedge block 24, it will push the third wedge block 24 to move outward. The third wedge block 24 drives the moving block 20 to move outward. Thus, the first wedge block 21 is separated from the second wedge block 22, and all the shock absorbers 3 can be automatically unlocked. Subsequently, the pressing plate 16 and the roller 19 will come into contact, and then the shock absorbers 3 will be automatically pushed outwards. From the above operations, it can be seen that during the upward movement of the pushing frame 15, the shock absorbers 3 can be automatically unlocked first and then automatically pushed out.

[0035] As Figure 6 shown, there are also four guiding members 26. Two guiding members 26 are fixedly connected to the front and rear sides of the upper plate 4. A sliding iron plate 27 is slidably connected between the left and right guiding members 26. Elastic members 28 are connected between the left and right sides of the sliding iron plate 27 and the upper plate 4. Clamping pins 29 are fixedly connected to the left and right sides of the sliding iron plate 27. The clamping pins 29 are slidably connected to the upper plate 4. Perforated blocks 30 are fixedly connected to the tops of the shock-absorbing columns 304. The perforated blocks 30 are in clamping fit with the clamping pins 29.

[0036] As Figure 6 shown, there is also an electromagnet 31. The electromagnets 31 are respectively fixedly connected to the front and rear sides of the upper plate 4. The electromagnets 31 and the sliding iron plate 27 are in magnetic adsorption cooperation. Contact buttons 32 are connected to the left and right sides of the top of the lower plate 2. The contact buttons 32 and the electromagnets 31 are electrically connected through a control module. The contact buttons 32 are in pressing cooperation with the lower pressing plate 8.

[0037] As described in the previous text, the upper plate 4 is connected between the tops of the shock-absorbing columns 304 by bolts and nuts. However, every time the shock absorber 3 is installed, the bolts and nuts need to be removed and then the upper plate 4 needs to be removed, which is very troublesome. Therefore, this embodiment provides the following solution: when the lower pressing plate 8 moves downward and contacts the contact button 32, the contact button 32 controls the electromagnet 31 to work. The electromagnet 31 magnetically adsorbs the sliding iron plate 27 through magnetism. The sliding iron plate 27 moves inward. The sliding iron plate 27 drives the clamping pin 29 to move inward. The clamping pin 29 can be inserted into the perforated block 30, and the elastic member 28 is compressed. Thus, through the clamping fit between the clamping pin 29 and the perforated block 30, the upper plate 4 can be fixed above the shock-absorbing column 304. Then, after the lower pressing plate 8 moves upward and separates from the contact button 32, the electromagnet 31 stops working. At this time, under the action of the elastic member 28, it will drive the sliding iron plate 27 and the clamping pin 29 to move outward and reset. Thus, the upper plate 4 can be removed from above the shock-absorbing column 304.

[0038] As Figures 8 - 9As shown in the figure, it further includes side plates 34 which are symmetrically arranged left and right. The side plates 34 symmetrically arranged left and right are placed between the left and right sides of the lower plate 2. Rotating ventilation plates 35 are rotatably connected to both the front and rear sides between the side plates 34. The rotating ventilation plates 35 are made of iron. Magnet blocks 36 are connected to both the front and rear sides of the side plates 34. The magnet blocks 36 and the rotating ventilation plates 35 are magnetically adsorbed to each other.

[0039] In order to protect the transformer 1, side plates 34 are provided to protect the left and right sides of the transformer 1, and the rotating ventilation plates 35 can protect the front and rear sides of the transformer 1. The ventilation holes provided on the rotating ventilation plates 35 facilitate the heat dissipation of the transformer 1. Moreover, when people need to install the shock absorber 3, the rotating ventilation plates 35 can be manually rotated outwards to open. After installation, the rotating ventilation plates 35 are rotated back to their original positions, and the magnet blocks 36 are magnetically adsorbed to the rotating ventilation plates 35 again, which can limit the positions of the rotating ventilation plates 35.

[0040] As Figures 8 - 9 As shown in the figure, it further includes a bottom plate 33. The bottom plate 33 is located below the lower plate 2. Support seats 37 are symmetrically welded in the front and rear directions on both the left and right sides of the bottom plate 33. Electric sliders 38 are fixedly connected to the support seats 37. Lifting blocks 39 are slidably connected to the electric sliders 38. The lifting blocks 39 are fixedly connected to the side plates 34.

[0041] Since the size specifications of the transformers 1 are inconsistent, some transformers 1 have different heights. If the height of the transformer 1 is relatively high, the lifting blocks 39 can be controlled to move upwards by the electric sliders 38. The lifting blocks 39 drive the side plates 34 and the rotating ventilation plates 35 to move upwards, so that the transformers 1 with relatively high heights can also be surrounded and protected. If the height of the transformer 1 is relatively low, the lifting blocks 39 are controlled to move downwards by the electric sliders 38.

[0042] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
