Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to an intelligent earthquake-resistant protection transformer. Background Art

[0002] In order to protect the precision components inside the transformer from various forms of mechanical shock and vibration, ensure the long-term stable operation of the equipment, and prevent failures or damages caused by vibration, it is necessary to carry out effective anti-seismic design for the transformer.

[0003] Ordinary spring shock absorbers are mainly used to absorb high-frequency vibrations and relieve the impact force through elastic deformation. However, for low-frequency and large-amplitude impacts (such as ground vibrations caused by earthquakes), their shock absorption methods are single and the energy absorption capacity is relatively limited.

[0004] In order to form a multi-level energy absorption system and enhance the overall shock absorption effect, the present invention provides an intelligent earthquake-resistant protection transformer. Summary of the Invention

[0005] In order to overcome the above-mentioned technical drawbacks, the present invention provides an intelligent earthquake-resistant protection transformer.

[0006] An intelligent earthquake-resistant protection transformer includes two chassis. At least two energy absorption tubes are fixedly connected to the top of the chassis. Blocking sheets symmetrically distributed along the energy absorption tubes are fixedly connected inside the energy absorption tubes. When the energy absorption tubes absorb energy, the blocking sheets are folded. A fixed tube is clamped at the top of the energy absorption tube. A lifting frame is slidably connected to the fixed tube. Both the fixed tube and the lifting frame are provided with a ventilation structure. When the lifting frame resets, it contacts the folded blocking sheets. A transformer body is fixedly connected between the lifting frames. The transformer body is slidably connected to a connecting frame. Each energy absorption tube is fixedly connected to the connecting frame. A first spring is fixedly connected between the lifting frame and the adjacent fixed tube. An intelligent alarm component is arranged on one side of the chassis.

[0007] More preferably, two ventilation holes are opened in the fixed tube, so that the gas in the energy absorption tube can be discharged through the ventilation holes.

[0008] More preferably, a ventilation channel is opened in the lifting frame, so that the lifting frame can slide relative to the fixed tube.

[0009] More preferably, the intelligent alarm component includes a pressure sensor fixedly connected inside each energy absorption tube, an alarm is fixedly connected to one side of the chassis, and the pressure sensor is electrically connected to the alarm through a control module.

[0010] More preferably, the blocking sheets are made of a ductile material.

[0011] More preferably, it further includes a slide rail, which is fixedly connected to the connecting frame. The slide rail is slidably connected with slide frames symmetrically distributed along the slide rail. The slide frames are rotatably connected with connecting rods symmetrically distributed along the slide frames. A connecting block is rotatably connected between adjacent connecting rods, and the connecting block is fixedly connected to the transformer main body.

[0012] More preferably, it further includes second springs symmetrically distributed along the slide frames, and the second springs are fixedly connected between adjacent slide frames and the connecting frame.

[0013] More preferably, it further includes a pressure-bearing rod corresponding to the energy-absorbing tube. The pressure-bearing rod is fixedly connected to adjacent bottom frames. The pressure-bearing rod is rotatably connected with a push rod. The top of the pressure-bearing rod contacts the bottom of the connecting frame. An activity groove is formed on one side of the push rod close to the adjacent slide frame, and the push rod is movably connected to the adjacent push rod through the activity groove. A protrusion is arranged on one side of the pressure-bearing rod close to the adjacent push rod, and the push rod rotates a certain angle to contact the protrusion.

[0014] More preferably, a water outlet for discharging the water entering the energy-absorbing tube is formed at the lower part of the energy-absorbing tube.

[0015] Advantages of the present invention: By arranging components such as the energy-absorbing tube fixing tube lifting frame, when the transformer main body is subjected to multiple small-amplitude vibrations, the first spring is intermittently compressed and reset. When it is subjected to a single large-amplitude vibration, the energy-absorbing tube absorbs energy, and the lifting frame intermittently contacts the folded blocking piece during the reset time, so as to achieve the effect of decelerating and rebounding of the transformer main body and avoid secondary injury during the rebound.

[0016] In the present invention, when the lifting frame moves downward to contact the pressure sensor, the alarm gives an alarm, so as to timely remind the staff to replace the energy-absorbing tube with a blocking piece and repair the transformer main body in time.

[0017] In the present invention, by adding the second springs arranged horizontally, the load of the first springs arranged vertically is reduced, and the transformer main body is jointly borne by the slide frames, connecting rods and connecting blocks to share part of the weight.

[0018] In the present invention, the top of the pressure-bearing rod bears the weight of the connecting frame and the transformer main body, so as to share the pressure received by the energy-absorbing tube, prevent the energy-absorbing tube from being gradually collapsed due to the pressure brought by the vibration of the transformer main body for a long time and losing the energy-absorbing function, and when it is subjected to a single large-amplitude vibration, the pressure-bearing rod is automatically turned away to allow the energy-absorbing tube to buffer.

Specific embodiments

[0028] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific embodiments, but does not limit the protection scope and application scope of the present invention.

[0029] Embodiment 1: An intelligent earthquake-resistant protective transformer, as Figures 1 - 3As shown in the figure, it includes two chassis 1021. On the front and rear sides of the top of each chassis 1021, energy-absorbing tubes 103 are fixedly connected. At the lower part of the energy-absorbing tube 103, a water outlet 401 for discharging the water entering it is opened. Inside the energy-absorbing tube 103, three blocking pieces 1031 symmetrically distributed left and right along the energy-absorbing tube 103 are fixedly connected from top to bottom. The blocking pieces 1031 are made of a ductile material. When the energy-absorbing tube 103 absorbs energy, the blocking pieces 1031 are folded. At the top of the energy-absorbing tube 103, a fixed tube 104 is snap-connected. Vent holes are opened at the bottom and side of the fixed tube 104, so that the gas in the energy-absorbing tube 103 can be discharged through the vent holes at the bottom and side in sequence. A lifting frame 105 is slidably connected to the upper part of the fixed tube 104 in the up and down direction. A ventilation channel is opened inside the lifting frame 105, so that the lifting frame 105 can slide relative to the fixed tube 104 in the up and down direction. When the lifting frame 105 is reset, it contacts the folded blocking pieces 1031 to play a decelerating role. A transformer main body 101 is fixedly connected between the lifting frames 105. The lower part of the transformer main body 101 is slidably connected to a connecting frame 102 in the up and down direction. Each energy-absorbing tube 103 is fixedly connected to the connecting frame 102. A first spring 106 is fixedly connected between the lifting frame 105 and the adjacent fixed tube 104. A pressure sensor 107 is fixedly connected inside each energy-absorbing tube 103. An alarm 108 is fixedly connected to the front side of the top of the left chassis 1021. The pressure sensor 107 is electrically connected to the alarm 108 through a control module.

[0030] When the transformer main body 101 is subjected to multiple small-amplitude vibrations, each time the transformer main body 101 transmits the vibration sensation to the lifting frame 105, causing the lifting frame 105 to slide up and down intermittently relative to the fixed tube 104, and the first spring 106 is intermittently compressed and reset; When the transformer main body 101 is subjected to a single large-amplitude vibration, the first spring 106 is first compressed to the limit. Subsequently, the transformer main body 101, the connecting frame 102, the fixed tube 104, the lifting frame 105, and the first spring 106 start to compress the energy-absorbing tube 103 as a whole, and the bent blocking pieces 1031 are further folded from top to bottom in sequence. When the vibration disappears, only the first spring 106 drives the lifting frame 105 to move upward relative to the fixed tube 104 to return to its original position, thereby driving the transformer main body 101 to return to its original position. During the upward return process of the lifting frame 105, it will intermittently contact the folded blocking pieces 1031, thereby achieving the effect of decelerating the rebound of the transformer main body 101 and avoiding secondary shock damage during the rebound.

[0031] After the energy-absorbing tube 103 is compressed, it cannot rebound. To ensure that the energy-absorbing tube 103 with the blocking pieces 1031 can be replaced in time and the transformer main body 101 can be repaired, the lifting frame 105 moves down to contact the pressure sensor 107. The pressure sensor 107 transmits an electrical signal to the control module. The control module receives the electrical signal and controls the alarm 108 to emit an alarm, thereby timely reminding the staff to perform replacement and repair operations.

[0032] As Figures 4 - 6 shown, it further includes a slide rail 201. The slide rail 201 is fixedly connected to the connecting frame 102. A slide carriage 202 symmetrically distributed left and right along the slide rail 201 is slidably connected to the slide rail 201 in the left - right direction. Connecting rods 203 symmetrically distributed front and back along the slide carriage 202 are rotatably connected to the slide carriage 202. A connecting block 205 is rotatably connected between adjacent connecting rods 203. The connecting block 205 is fixedly connected to the bottom of the transformer body 101. Second springs 204 symmetrically distributed front and back along the slide carriage 202 are fixedly connected between adjacent slide carriages 202 and the connecting frame 102.

[0033] Since the transformer body 101 is usually heavy, the vertically arranged first spring 106 bears a large load. To reduce the load on the first spring 106, the horizontally arranged second springs 204 are added, and the transformer body 101 is jointly borne by the slide carriage 202, the connecting rod 203 and the connecting block 205 to share part of the weight. The connecting block 205 moves up and down synchronously with the transformer body 101. When the connecting block 205 descends, it pushes the slide carriage 202 to slide along the slide rail 201 towards the side where the second spring 204 is compressed through the connecting rod 203.

[0034] As Figures 7 - 8 shown, it further includes a pressure - bearing rod 301 corresponding to the energy - absorbing tube 103. The pressure - bearing rod 301 is fixedly connected to the adjacent chassis 1021. The upper part of the pressure - bearing rod 301 is rotatably connected to a push rod 302. The top of the pressure - bearing rod 301 contacts the bottom of the connecting frame 102. An activity groove is formed on the side of the push rod 302 close to the adjacent slide carriage 202, and the push rod 302 is movably connected to the adjacent push rod 302 through the activity groove. A protrusion 303 is arranged on the upper part of the pressure - bearing rod 301, and the push rod 302 contacts the protrusion 303 when rotating greatly.

[0035] To prevent the energy - absorbing tube 103 from gradually collapsing due to the pressure brought by the vibration of the transformer body 101 for a long time and losing the energy - absorbing function, the specific operation is as follows: By bearing the weight of the connecting frame 102 and the transformer body 101 at the top of the pressure - bearing rod 301, the pressure borne by the energy - absorbing tube 103 is shared. When the transformer body 101 vibrates and descends, and the slide carriage 202 moves to the left and right sides, the slide carriage 202 drives the push rod 302 to swing; If the transformer body 101 is subjected to multiple small - amplitude vibrations, the moving distance of the slide carriage 202 is relatively short, so that the swinging amplitude of the push rod 302 is not enough to contact the protrusion 303. Thus, only the push rod 302 rotates relative to the pressure - bearing rod 301 alone, and the pressure - bearing rod 301 is always in a static pressure - bearing state; When the transformer main body 101 is subjected to a single large shock, the descending amplitude of the transformer main body 101 and the connecting block 205 increases, thereby pushing the sliding frame 202 to move a long distance to both sides through the connecting rod 203. The sliding frame 202 pushes the pushing rods 302 on both sides to swing greatly. During the swinging process of the pushing rods 302, they rotate idly first, then contact the protrusions 303, and push the pressure-bearing rods 301 to rotate synchronously through the protrusions 303, so that the pressure-bearing rods 301 no longer bear the gravity brought by the connecting frame 102 and the transformer main body 101, and the energy-absorbing pipe 103 is buffered.

[0036] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
