Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and particularly relates to a self-locking and anti-theft transformer. Background Art

[0002] In modern society, a transformer is one of the important devices in the power supply and distribution systems of industrial and mining enterprises and civil buildings. The main components of a transformer are a primary coil, a secondary coil, and an iron core. Currently, the structure of an oil-immersed transformer is that the transformer core body composed of the iron core and the coil is placed inside the body. After opening the upper cover of the body, it is very easy to lift out the iron core and the coil, which allows some lawless elements to steal the iron core and the coil for economic gain, affecting the normal operation of the power supply and distribution system and causing property losses. In the prior art, most anti-theft transformers adopt the method of fixing and sealing the transformer inside a protective box to achieve the anti-theft effect. However, during the processes of anti-theft fixing and disassembly, excessive manual intervention is required, and it is difficult to achieve the self-locking effect of locking the transformer when it is placed in the box. The overall operation is relatively inconvenient. Moreover, when the transformer needs to be repaired, it is necessary to enter the box, and the internal space of the box is often relatively narrow, which is not convenient for maintenance. At the same time, when an emergency occurs, it is difficult to quickly remove the transformer, resulting in relatively serious consequences. In view of the above technical defects, a solution is proposed herein. Summary of the Invention

[0003] To overcome the above-mentioned defects of the prior art, the present invention provides a self-locking and anti-theft transformer. When the transformer is moved into the protective box by a self-locking control mechanism, a self-locking effect will be formed without excessive intervention by the staff. With the cooperation of a moving component, the transformer can be quickly removed, which is convenient for maintenance. And with the cooperation of a clamping component, the transformer can be further fixed, and at the same time, it is convenient for quick disassembly in case of an emergency, so as to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention adopts the following technical scheme: A self-locking and anti-theft transformer, including a protective box, an alarm is fixed at the bottom of the protective box, and a base is fixed at the bottom layer inside the protective box. A box door is arranged at the front end of the protective box. A moving component is installed between the box door and the base. A support plate is arranged on the upper surface at the rear end of the base. A self-locking control mechanism is installed between the support plate and the base. A toothed plate is fixed on the upper surface of the support plate, and two connecting lead screws are symmetrically and rotatably connected to both sides inside the support plate. An interface is provided at the front end of the connecting lead screw. A moving plate is sleeved on the outer layers of the two connecting lead screws on the upper surface of the support plate. An installation plate is arranged on the upper surface of the moving plate, and a clamping component is installed between the moving plate and the installation plate. A transformer body is fixed on the upper surface of the installation plate.

[0005] Furthermore, the self-locking control mechanism includes four guiding sliding grooves equidistantly arranged in a rectangular shape inside the base. A guiding sliding rod is fixed inside the guiding sliding groove. A guiding sliding block is sleeved outside the guiding sliding rod. A spring sleeved outside the guiding sliding rod is fixed on one side of the guiding sliding block. A gravity sensor is installed inside the guiding sliding block and is electrically connected to the alarm. A first latch slidably connected inside the base is fixed to the bottom of one of the guiding sliding blocks. A connecting rod passing through and extending outside the guiding sliding groove is rotatably connected to the top end of the guiding sliding block. The top ends of the four connecting rods are all rotatably connected to the bottom of the support plate.

[0006] Furthermore, two sliding sleeves are symmetrically fixed on both sides of the support plate. A sliding rod is connected through the inside of the sliding sleeve. A third lead screw rotatably connected inside the base is arranged inside the sliding rod. A lifting block is fixed to the outer layer of the bottom of the sliding rod. A first bevel gear is fixed to the bottom of the third lead screw. A second bevel gear is arranged below the first bevel gear. A rotating shaft rotatably connected inside the base is commonly passed through the two second bevel gears. One side of the rotating shaft passes through and extends outside the protective box, and a special-shaped socket is opened on the side surface of the rotating shaft.

[0007] Furthermore, the moving component includes two second lead screws symmetrically rotatably connected to both sides of the upper surface of the base. The front end of the second lead screw passes through and extends outside the base and is fixed with a synchronous pulley. An embedding block is fixed at the position corresponding to the connection port at the rear end of the second lead screw. A synchronous belt is rotatably connected between the two synchronous pulleys. A motor is fixed to the front end of one of the synchronous pulleys.

[0008] Furthermore, a worm is sleeved outside the second lead screw. A worm gear rotatably connected inside the protective box is arranged on one side of the worm. A first lead screw rotatably connected to the upper surface of the worm gear is fixed to the upper surface of the worm gear. A screw sleeve is sleeved outside the first lead screw. One side of each of the two screw sleeves is fixed to the box door.

[0009] Furthermore, a through groove is opened at the position corresponding to the box door at the top end of the protective box. An engaging block is fixed to the bottom of the box door. A first card slot is opened at the position corresponding to the first latch on one side of the engaging block. A notch is opened on the upper surface of the base at the position corresponding to the engaging block.

[0010] Furthermore, the engaging component includes four fixed disks fixedly arranged in a rectangular shape on the upper surface of the lifting block. A rotating disk rotatably connected inside the lifting block is fixed to the bottom of the fixed disk. A gear rotatably connected to the bottom of the engaging component is fixed to the bottom of the rotating disk. A slot is opened at the position corresponding to the toothed plate at the bottom of the engaging component.

[0011] Furthermore, two second clamping blocks are symmetrically slidably connected on both sides of the fixed disk, and a limiting slider is fixed at the bottom of the second clamping block, which passes through and extends to the outside of the rotating disk. An arc-shaped sliding groove is opened at the position of the limiting slider inside the rotating disk.

[0012] Furthermore, a guide groove is provided at the bottom of the mounting plate at a position corresponding to the fixing plate, and a second clamping groove is provided inside the guide groove at a position corresponding to the second clamping block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a self-locking control mechanism is provided to perform self-locking control on the transformer body. When the transformer body is in the position of the support plate, the support plate is pressed down due to its own gravity. During the process of the support plate descending, the guide slider and the spring drive the first card block to move into the first card slot. At this time, a card engagement is formed, and the protective box is in a sealed state as a whole. It cannot be opened except for violent destruction and specially configured opening tools. When the self-locking state needs to be released, a specially configured tool is used to engage with the special-shaped socket on the side of the rotating shaft and rotate the rotating shaft. The rotating shaft cooperates with the first bevel gear and the second bevel gear to drive the third screw rod to rotate, thereby driving the slide bar to rise. The slide bar rises and cooperates with the lifting block and the sliding sleeve to drive the support plate to rise until it moves to the same horizontal line as the upper surface of the base. At this time, the self-locking state is released, and the transformer body can be moved out through the moving component. The self-locking control is simple and does not require excessive intervention from the staff. When the transformer is moved by violent destruction, the gravity sensor inside the moving block sends a signal to the alarm to send an alarm, thereby effectively and more strictly protecting the transformer body. 2. In the present invention, a moving assembly is used to control the movement of the transformer body. When the transformer body needs to be inspected, the starting motor cooperates with the synchronous belt and the synchronous wheel to drive the two second screws to rotate. The second screws rotate and cooperate with the connecting screw to drive the moving plate to move. At the same time, the second screw rotates and cooperates with the worm and worm wheel to drive the first screw to rotate. The first screw rotates and cooperates with the screw sleeve to drive the box door to rise. The two cooperate with each other. As the box door opens, the moving plate drives the transformer body to move out of the box, and then the transformer body can be inspected. The box door body is designed to be flat and has no gripping points. It is difficult to open it violently by external force, which forms further protection for the transformer.

[0014] 3. A clamping component is provided in the present invention. When the moving plate moves to the position of the support plate, the toothed plate drives the gear to rotate, and the rotation of the gear drives the rotating disc to rotate. Then, in cooperation with the arc-shaped chute and the limiting slider, the second clamping block is driven out of the fixed disc and inserted into the second clamping block, so that the mounting plate and the moving plate are clamped and fixed, making it difficult to disassemble. When the moving plate moves out of the support plate, the clamping component runs in the reverse direction at this time, and the second clamping block is disengaged from the second clamping groove. When an emergency occurs, there is no need to disassemble the transformer body, and the transformer body can be quickly removed together with the mounting plate, avoiding accidents caused by the complexity of disassembly and the urgency of time.

[0015] In summary, the present invention relies on the self-locking control mechanism to form an effective and tight self-locking effect on the transformer body. After self-locking is completed, it cannot be released except by violent destruction or special tools. At the same time, when the gravity sensor body detects a gravity change, it transmits a signal to the alarm to issue an alarm, effectively protecting the transformer. With the cooperation of the moving component and the clamping component, the transformer body can be freely moved out and into, and the transformer body can be quickly disassembled and assembled, facilitating the maintenance of the transformer body and the rapid emergency operation in case of an emergency.

Detailed implementation manner

[0018] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention. Embodiment

[0019] In order to solve the problem that most of the anti-theft transformers in the prior art fix and seal the transformer inside the protective box to achieve the anti-theft effect, but too much manual intervention is required during the anti-theft fixing and disassembly processes, it is difficult to achieve the self-locking effect of locking the transformer when it is placed in the box, and the overall is rather inconvenient.

[0020] Such as Figures 1-4As shown in the figure, a self-locking anti-theft transformer includes a protective box 1. An alarm 10 is fixed at the bottom of the protective box 1, and a base 3 is fixed at the bottom layer inside the protective box 1. A box door 2 is provided at the front end of the protective box 1. The box door 2 is designed without a gripping convex part, making it difficult to forcibly lift the box door 2 by external force. A moving component 7 is installed between the box door 2 and the base 3. The moving component 7 includes two second lead screws 14 symmetrically and rotatably connected to both sides of the upper surface of the base 3. The front end of the second lead screw 14 penetrates and extends outside the base 3 and is fixed with a synchronous pulley 6. And an embedding block 38 is fixed at the rear end of the second lead screw 14 corresponding to the position of the engagement interface 24. In the initial state, the second lead screw 14 is engaged with the engagement interface 24 through the embedding block 38. At this time, when the second lead screw 14 rotates, it drives the connecting lead screw 26 to rotate. When the second lead screw 14 and the connecting lead screw 26 drive the moving plate 12 to completely move to the upper surface of the support plate 15, the embedding block 38 and the engagement interface 24 are exactly located above and below respectively. A synchronous belt 5 is rotatably connected between the two synchronous pulleys 6, and a motor 4 is fixed at the front end of one of the synchronous pulleys 6; A worm 36 is sleeved on the outer layer of the second lead screw 14. A worm gear 37 rotatably connected inside the protective box 1 is provided on one side of the worm 36. A first lead screw 11 rotatably connected is fixed on the upper surface of the worm gear 37. A notch is opened at the position corresponding to the first lead screw 11 inside the protective box 1. A screw sleeve 35 is sleeved on the outer layer of the first lead screw 11. One side of each of the two screw sleeves 35 is fixed to the box door 2. A through groove 9 is opened at the position corresponding to the box door 2 at the top end of the protective box 1. When the box door 2 rises, it moves out of the inside of the protective box 1 through the through groove 9. A connecting block 28 is fixed at the bottom of the box door 2. A first card slot 29 is opened at the position corresponding to the first card block 19 on one side of the connecting block 28. A notch 13 is opened at the position corresponding to the connecting block 28 on the upper surface of the base 3.

[0021] When protecting the transformer body 16, the transformer body 16 is fixed to the mounting plate 17. The motor 4 is started to drive the second lead screw 14 to rotate in cooperation with the synchronous belt 5 and the synchronous pulley 6. The rotation of the second lead screw 14 drives the moving plate 12 to move. The moving plate 12 drives the transformer body 16 to move into the protective box 1. At the same time, when the second lead screw 14 rotates, it drives the first lead screw 11 to rotate in cooperation with the worm 36 and the worm gear 37. The rotation of the first lead screw 11 drives the base 3 to descend in cooperation with the screw sleeve 35. When the transformer body 16 is located at the position of the sliding rod 25, the base 3 just completely drops, and at the same time, the connecting block 28 is inserted into the notch 13 to form a snap fit. Embodiment

[0022] In this embodiment, in order to solve the problem that when a theft-proof transformer in the prior art needs to be overhauled, it is necessary for workers to enter the box body, and the internal space of the box body is often relatively narrow, which is not convenient for overhaul.

[0023] Such as Figures 5-6As shown in the figure, the embodiment is a self-locking anti-theft transformer. On the upper surface of the rear end of the base 3, there is a support plate 15. An anti-theft control mechanism 8 is installed between the support plate 15 and the base 3. The anti-theft control mechanism 8 includes four guiding chutes 34 that are equidistantly arranged in a rectangular shape inside the base 3. A guiding slide bar 32 is fixed inside the guiding chute 34. A guiding slider 31 is sleeved outside the guiding slide bar 32. A spring 30 sleeved outside the guiding slide bar 32 is fixed on one side of the guiding slider 31. A gravity sensor 51 is installed inside the guiding slider 31. The gravity sensor 51 is preset according to the transformer body 16. When the transformer body 16 is damaged or components are missing, resulting in a change in the gravity detected by the gravity sensor 51, the gravity sensor 51 will send a signal to the alarm 10. The gravity sensor 51 is electrically connected to the alarm 10; A first latch 19 slidably connected inside the base 3 is fixed to the bottom of one of the guiding sliders 31. The top end of the guiding slider 31 is rotatably connected to a connecting rod 33 that penetrates and extends outside the guiding chute 34. The top ends of the four connecting rods 33 are all rotatably connected to the bottom of the support plate 15; Two sliding sleeves 27 are symmetrically fixed on both sides of the support plate 15. A sliding rod 25 penetrates through the inside of the sliding sleeve 27. A third lead screw 50 rotatably connected inside the base 3 is arranged inside the sliding rod 25. Internal threads adapted to the third lead screw 50 are arranged inside the sliding rod 25. A lifting block 18 is fixed to the outer layer of the bottom of the sliding rod 25. A first bevel gear 21 is fixed to the bottom of the third lead screw 50. A second bevel gear 22 is arranged below the first bevel gear 21. A rotating shaft 20 rotatably connected inside the base 3 penetrates through the inside of the two second bevel gears 22. One side of the rotating shaft 20 penetrates and extends outside the protection box 1. An irregular socket 23 is provided on the side surface of the rotating shaft 20.

[0024] When the transformer body 16 is moved into the protection box 1 and is located at the position of the support plate 15, the support plate 15 moves downward under the gravity of the transformer body 16. The downward movement of the support plate 15 drives the guiding slider 31 to move along the guiding slide bar 32 in cooperation with the connecting rod 33. The movement of one of the guiding sliders 31 drives the first latch 19 to move and insert into the first slot 29. At this time, the first slot 29 and the first latch 19 form a snap lock. At this time, the box door 2 is locked, that is, the protection box 1 is in a sealed state; When unlocking is required, a special tool matching the irregular socket 23 drives the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 drives the third lead screw 50 to rotate in cooperation with the first bevel gear 21 and the second bevel gear 22. The rotation of the third lead screw 50 drives the sliding rod 25 to rise. When the sliding rod 25 rises, the support plate 15 is driven to rise by the lifting block 18 and the sliding sleeve 27. As the support plate 15 rises, the first latch 19 moves out of the first slot 29. At this time, the box door 2 is unlocked. At the same time, the transformer body 16 can be moved out by starting the motor 4; When the protective box 1 is violently damaged, the transformer body 16 is damaged or the gravity detected by the gravity sensor 51 changes due to the lack of components, the gravity sensor 51 will transmit a signal to the alarm 10 at this time. The alarm 10 issues an alarm and warns the staff, so that the staff can quickly respond to protect the transformer body 16. Embodiment

[0025] This embodiment aims at the problem that in the prior art, when an emergency occurs in an anti-theft transformer, it is difficult to quickly remove the transformer, resulting in more serious consequences.

[0026] As Figures 7-9 shown, the embodiment is a self-locking anti-theft transformer. A toothed plate 42 is fixed on the upper surface of the support plate 15, and two connecting lead screws 26 are symmetrically and rotatably connected to both sides inside the support plate 15. An interface 24 is provided at the front end of the connecting lead screw 26. A moving plate 12 is sleeved on the outer layers of the two connecting lead screws 26 on the upper surface of the support plate 15. Limit plates are provided at the front and rear ends of the upper surface of the moving plate 12 to prevent the mounting plate 17 from slipping due to the inertia of the movement and stop when the moving plate 12 moves. An mounting plate 17 is provided on the upper surface of the moving plate 12, and a clamping component 41 is installed between the moving plate 12 and the mounting plate 17. The clamping component 41 includes four fixed disks 46 fixedly arranged in a rectangle on the upper surface of the lifting block 18. A rotating disk 49 rotatably connected to the inside of the lifting block 18 is fixed to the bottom of the fixed disk 46. A gear 43 rotatably connected to the bottom of the clamping component 41 is fixed to the bottom of the rotating disk 49. A slot 44 is provided at the bottom of the clamping component 41 corresponding to the position of the toothed plate 42; Two second clamping blocks 47 are symmetrically and slidably connected to both sides inside the fixed disk 46. A limit slider 45 fixedly connected to the bottom of the second clamping block 47 penetrates and extends to the outside of the rotating disk 49. An arc-shaped chute 48 is provided at the position corresponding to the limit slider 45 inside the rotating disk 49. A guiding groove 39 is provided at the bottom of the mounting plate 17 corresponding to the position of the fixed disk 46. When the second clamping block 47 is disengaged from the second clamping slot 40, the mounting plate 17 can be removed through the guiding groove 39. A second clamping slot 40 is provided at the position corresponding to the second clamping block 47 inside the guiding groove 39. The transformer body 16 is fixed to the upper surface of the mounting plate 17.

[0027] When the moving plate 12 moves to the position of the support plate 15, the gear 43 at the bottom of the moving plate 12 is driven by the toothed plate 42 to rotate. The rotation of the gear 43 drives the rotating disk 49 to rotate. The rotation of the rotating disk 49, in cooperation with the arc-shaped chute 48 and the limit slider 45, drives the second latch 47 to move out of the fixed disk 46 and insert into the second card slot 40 to form a latch. At this time, the mounting plate 17 and the moving plate 12 form a latch, that is, the transformer body 16 is completely fixed inside the protection box 1, and it cannot be moved unless it is forcibly disassembled; When it is necessary to move the transformer body 16 out for maintenance, when the moving plate 12 moves out, it drives the second latch 47 to retract into the fixed disk 46 through the toothed plate 42 and the gear 43, thereby releasing the latched state between the second latch 47 and the second card slot 40. When the transformer body 16 is moved out of the protection box 1, the transformer body 16 can be disassembled by directly removing the mounting plate 17, so as to cope with some emergency situations and avoid irreparable consequences caused by excessive time loss due to disassembly.

[0028] The working process and principle of the present invention: Step 1: When protecting the transformer body 16, fix the transformer body 16 to the mounting plate 17, start the motor 4, cooperate with the synchronous belt 5 and the synchronous pulley 6 to drive the second lead screw 14 to rotate. The rotation of the second lead screw 14 drives the moving plate 12 to move, and the moving plate 12 drives the transformer body 16 to move into the protection box 1. At the same time, when the second lead screw 14 rotates, it cooperates with the worm 36 and the worm gear 37 to drive the first lead screw 11 to rotate. The rotation of the first lead screw 11 cooperates with the screw sleeve 35 to drive the base 3 to descend. When the transformer body 16 is at the position of the slide bar 25, the base 3 just completely drops, and at the same time, the connecting block 28 is inserted into the notch 13 to form a latch; Step 2: When the transformer body 16 is moved into the protection box 1 and is at the position of the support plate 15, the support plate 15 is pressed downward by the gravity of the transformer body 16. The downward movement of the support plate 15 cooperates with the connecting rod 33 to drive the guide slider 31 to move along the guide slide bar 32. The movement of one of the guide sliders 31 drives the first latch 19 to move and insert into the first card slot 29. At this time, the first card slot 29 and the first latch 19 form a latch lock, and at this time the box door 2 is locked, that is, the protection box 1 is in a sealed state; When it is necessary to unlock, a special tool matching the special-shaped socket 23 drives the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 cooperates with the first bevel gear 21 and the second bevel gear 22 to drive the third lead screw 50 to rotate. The rotation of the third lead screw 50 drives the slide bar 25 to rise. When the slide bar 25 rises, it drives the support plate 15 to rise through the lifting block 18 and the sliding sleeve 27. As the support plate 15 rises, the first latch 19 moves out of the first card slot 29. At this time, the box door 2 is unlocked, and at the same time, the transformer body 16 can be moved out by starting the motor 4; When the protection box 1 is violently damaged, the transformer body 16 is damaged or the gravity detected by the gravity sensor 51 changes due to the lack of components, at this time the gravity sensor 51 will transmit a signal to the alarm 10, and the alarm 10 will issue an alarm and give a warning to the staff, so that the staff can quickly respond to protect the transformer body 16; Step 3: When the moving plate 12 moves to the position of the support plate 15, the gear 43 at the bottom of the moving plate 12 is driven by the toothed plate 42 to rotate. The rotation of the gear 43 drives the rotating disc 49 to rotate. The rotation of the rotating disc 49 cooperates with the arc-shaped chute 48 and the limit slider 45 to drive the second latch 47 out of the fixed disc 46 and insert it into the second card slot 40 to form a snap fit. At this time, the mounting plate 17 and the moving plate 12 form a snap fit, that is, the transformer body 16 is completely fixed inside the protection box 1, and it cannot be moved unless it is forcibly disassembled; When it is necessary to remove the transformer body 16 for maintenance, when the moving plate 12 is removed, the second latch 47 is driven by the toothed plate 42 and the gear 43 to retract into the fixed disc 46, thereby releasing the snap fit between the second latch 47 and the second card slot 40. After the transformer body 16 is removed from the inside of the protection box 1, the transformer body 16 can be disassembled by directly removing the mounting plate 17, so as to cope with some emergency situations and avoid irreparable consequences caused by excessive time loss due to disassembly.

[0029] In summary, the moving component 7 is used to drive the transformer body 16 to move into or out of the protection box 1, and at the same time control the closing and opening of the box door 2 to achieve a convenient control effect. The transformer body 16 can be quickly protected and maintained. At the same time, the box door 2 is designed without a handle and is difficult to be forcibly lifted. The self-locking control mechanism 8 is used to lock and close the whole protection box 1, and it is difficult to open without violence and special tools. The gravity sensor 51 is used to detect the gravity of the transformer body 16. When the gravity sensor 51 detects a gravity change during non-maintenance, a signal will be sent to the alarm 10 to form a warning effect. Finally, the clamping component 41 further clamps and locks the transformer body 16 during protection, making it difficult to disassemble, and at the same time facilitating the quick disassembly of the non-protected transformer body 16 in case of emergency, greatly reducing the time required for disassembly.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
