Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and in particular to a protection device based on an electric power engineering transformer substation and a use method thereof. Background Art

[0002] Substations are an important part of power projects. In order to avoid damage to substations as much as possible, protective equipment will be installed outside the substations to effectively protect them. The external protective equipment can prevent people from accidentally touching or entering, and can also block the intrusion of natural factors such as wind, rain, lightning and animals.

[0003] For example, the patent document with publication number CN114792949B discloses a protective device based on an electric power engineering substation. By setting a canopy on the top of the cabinet, the protective device can conveniently collect rainwater in the wild through the canopy, and then supply water to the inside of the protective seat. The drainage through the canopy can cause the water to flow into the inside of the circular tube through the water holes at both ends, and then flow into the inside of the water tank through the connecting mechanism, thereby ensuring the use of the water tank.

[0004] The above device has the following defects when used:

[0005] First, the above equipment reduces the intrusion of rainwater on the substation by setting up a canopy, but the rainwater is messy and fluid, and the water vapor inside it will enter the substation through the internal gap of the substation, causing electrical equipment to short-circuit, get damp, and reduce insulation performance, affecting the normal operation of the equipment, and even causing equipment damage and power failure;

[0006] Secondly, when a large amount of rainwater accumulates inside the substation, it will soak the internal equipment of the substation, causing the foundation of the equipment to loosen and fall over, making the substation vulnerable to mechanical damage.

[0007] Therefore, we propose a protection device based on power engineering substation and its use method to solve the above problems. Summary of the invention

[0008] 1. Technical issues to be solved

This solves the problem that when the existing outdoor box-type substation is exposed for use, water vapor will enter the interior of the substation through the internal gaps of the substation, causing short circuits in electrical equipment, moisture, reduced insulation performance, and other problems, thereby affecting the normal operation of the equipment.

[0038] 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 creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer toFigures 1 - 5 , a substation protection device based on electric power engineering, including a substation base body 1 and a mounting seat 2 arranged on the top of the substation base body 1. The longitudinal section of the mounting seat 2 is arranged in a T shape and is fixedly connected to the top of the substation base body 1 by screwing: a rain cover 3 is fixedly arranged on the top of the mounting seat 2, and a protective component is sleeved outside the substation base body 1. The protective component includes a plurality of connecting rings 4 arranged at intervals, a rainproof cloth 5 is fixedly arranged between two adjacent connecting rings 4, a sealing ring 6 is fixedly arranged on the top of the top connecting ring 4, and the sealing ring 6 is in contact and cooperation with the bottom of the rain cover 3;

[0040] Fixed rings 7 are fixedly arranged on both sides of the inner wall of the upper rainproof cloth 5. A winding protection mechanism is arranged between the two fixed rings 7 and the rain cover 3. The winding protection mechanism is used to unfold the protective component. The winding protection mechanism includes two symmetrically arranged hoisting wheels 11. The hoisting wheels 11 are fixedly arranged at the bottom of the rain cover 3, and a lifting rope 12 is internally driven. The lower end of the lifting rope 12 is fixedly wound inside the connecting ring 4. A connecting bolt 27 is threaded through the outer wall of the fixed ring 7, and the connecting bolt 27 is tightly pressed against the outer wall of the lifting rope 12. A rotating ring 13 is rotatably sleeved on the upper end of the outer part of the mounting seat 2. The upper end of the lifting rope 12 is fixedly connected to the outer wall of the rotating ring 13. An inspection opening 28 is opened on the outer part of the protective component. A cloth curtain 29 is electrostatically adsorbed outside the inspection opening 28, and the upper end of the cloth curtain 29 is fixedly arranged on the outer wall of the protective component.

[0041] When the substation is set up, the protective component is arranged outside the substation. At the same time, components such as the mounting seat 2 and the rain cover 3 are installed on the top of the substation base body 1 to directly block the rain above. When it rains, the rotating ring 13 is driven to rotate, driving the connected lifting rope 12 to move on the hoisting wheel 11. Since the lower end of the lifting rope 12 is fixedly wound inside the fixed ring 7 and is pressed by the connecting bolt 27, the position of the lifting rope 12 is fixed. At this time, the lifting rope 12 pulls the fixed ring 7 upward, and the protective component is unfolded. At this time, the connecting ring 4 and the rainproof cloth 5 inside the protective component are slowly opened and cover the outside of the substation base body 1 to provide rain protection for the substation base body 1. At the same time, the opening of the cloth curtain 29 and the inspection opening 28 allows the protective component to be opened for maintenance of the substation base body 1 when the protective component is hermetically covered outside the substation base body 1, improving the multi-functionality of the protection device.

[0042] A driving winding mechanism for driving the rotation of the rotating ring 13 is arranged on the outer wall of the rotating ring 13. The driving winding mechanism includes a driving motor 14. A mounting plate 15 is fixedly arranged on the top of the mounting seat 2. The driving motor 14 is fixedly arranged on the outer wall of the mounting plate 15. The end of the output shaft of the driving motor 14 passes through the mounting plate 15 and is fixedly provided with a reciprocating lead screw 16. A driving rack 17 is threadedly sleeved on the rod wall of the reciprocating lead screw 16. The driving rack 17 is in contact with the lower end of the mounting seat 2 and is provided with a transmission gear 18 in cooperation. The transmission gear 18 is fixedly sleeved with the rotating ring 13.

[0043] In order to enable the protection component to be stably deployed, the driving motor 14 can be turned on. Its output shaft drives the reciprocating lead screw 16 to rotate. Since the driving rack 17 is in threaded cooperation with the reciprocating lead screw 16, the rotation of the reciprocating lead screw 16 causes the driving rack 17 to reciprocate horizontally at the lower end of the mounting seat 2. When the driving rack 17 moves, it interacts with the transmission gear 18, and the transmission gear 18 rotates accordingly. The transmission gear 18 is fixedly sleeved with the rotating ring 13, so that the transmission gear 18 drives the rotating ring 13 to rotate, providing power for the deployment of the protection component and realizing the function of automatically deploying the protection component.

[0044] Two symmetrically arranged connecting rods 8 are fixedly provided on the outer wall of the mounting seat 2. A support ring 9 is fixedly sleeved on the rod walls of the two connecting rods 8. The support ring 9 is arranged below the rain cover 3 and sleeved on the outside of the substation base body 1. A blowing and rainproof mechanism is provided outside the support ring 9. The blowing and rainproof mechanism is used to prevent external water vapor. The blowing and rainproof mechanism includes two symmetrically arranged air curtain machines 19. Two symmetrically arranged guide plates 20 are in contact with the outer wall of the support ring 9. The air curtain machines 19 are fixedly arranged at the bottom of the guide plates 20. An elastic telescopic rod 21 is fixedly provided at the upper end of the outer wall of the guide plate 20. One end of the elastic telescopic rod 21 away from the guide plate 20 is fixedly provided with a sleeve plate 22. The sleeve plate 22 is fixedly sleeved with the rotating ring 13.

[0045] When the rotating ring 13 rotates, the sleeve plate 22 fixedly sleeved with it rotates accordingly. The sleeve plate 22 drives the guide plate 20 to move through the elastic telescopic rod 21. The guide plate 20 moves along the outer wall of the support ring 9, causing the air curtain machines 19 to revolve around the support ring 9 reciprocally. At this time, when the air curtain machines 19 work, they blow out air, forming an air curtain during the deployment process of the protection component to prevent external water vapor from entering the interior of the protection component. The elastic telescopic rod 21 can perform a certain telescopic adjustment according to the rotation of the rotating ring 13 to ensure that the guide plate 20 and the air curtain machines 19 can move smoothly around the support ring 9 and effectively block the water vapor.

[0046] A rain sensor 26 is fixedly provided on the top of the rain cover 3. The rain sensor 26 is electrically matched with the single-chip microcomputer 10. The single-chip microcomputer 10 is fixedly provided at the lower end of the mounting seat 2. The single-chip microcomputer 10 is electrically matched with the winding protection mechanism and the blowing and rainproof mechanism. A pressing block 23 is fixedly provided at the bottom of the rain cover 3. A groove 24 is opened at the top of the sealing ring 6. A pressure sensor 25 is fixedly embedded in the inner wall of the groove 24. The pressing block 23 is arranged in cooperation with the pressure sensor 25. The pressure sensor 25 is electrically matched with the single-chip microcomputer 10.

[0047] When in use at a substation, the rain sensor 26 monitors in real time whether there is rain. Once rain is detected, a signal is sent to the single-chip microcomputer 10. After receiving the signal, the single-chip microcomputer 10 controls the driving motor 14 to start, thereby starting the winding protection mechanism to deploy the protection component. At the same time, the air curtain machine 19 is controlled to start, and it revolves around the support ring 9 reciprocally to perform the waterproof vapor work. When the protection component is deployed in place, the pressure sensor 25 on the top of the sealing ring 6 is subjected to the pressure of the pressing block 23, and a pressure signal is sent to the single-chip microcomputer 10. After receiving the signal, the single-chip microcomputer 10 controls the winding protection mechanism and the blowing and rainproof mechanism to stop working. At this time, the protection component seals and covers the substation base body to achieve automatic rainproof protection control.

[0048] A usage method of a protection device for a power engineering substation is as follows:

[0049] First, all components are arranged on the outside of the box-type substation, and the rain sensor 26 is used to monitor rain. When rain is detected, the single-chip microcomputer 10 receives the signal and controls the winding protection mechanism to start. The winding protection mechanism lifts the protection component so that the protection component unfolds and covers the outside of the substation base body 1;

[0050] Second, during the unfolding process of the protection component, the single-chip microcomputer simultaneously controls the blowing and rainproof mechanism to start, so that the two air curtain machines 19 revolve around the support ring 9 reciprocally, and the air curtain machines 19 blow air to prevent external water vapor from entering the inside of the protection component when the protection component unfolds;

[0051] Finally, the pressure sensor 25 on the top of the sealing ring 6 is pushed by the pressing block 23, and the single-chip microcomputer 10 receives the pressure signal and controls the winding protection mechanism and the blowing and rainproof mechanism to close, so that the protection component seals and covers the substation base body 1.

[0052] In summary, for the protection device and usage method for a power engineering substation, when in use:

[0053] First, the rain sensor 26 monitors in real time whether there is rain. Once rain is detected, a signal is sent to the single-chip microcomputer 10. After receiving the signal, the single-chip microcomputer 10 controls the driving motor 14 to start, thereby starting the winding protection mechanism to deploy the protection component. At the same time, the air curtain machine 19 is controlled to start, and it revolves around the support ring 9 reciprocally to perform the waterproof vapor work. When the protection component is deployed in place, the pressure sensor 25 on the top of the sealing ring 6 is subjected to the pressure of the pressing block 23, and a pressure signal is sent to the single-chip microcomputer 10. After receiving the signal, the single-chip microcomputer 10 controls the winding protection mechanism and the blowing and rainproof mechanism to stop working. At this time, the protection component seals and covers the substation base body to achieve automatic rainproof protection control;

[0054] When rain is detected, the drive motor 14 is controlled to turn on, and at this time, the reciprocating lead screw 16 is driven to rotate. Since the drive rack 17 is in threaded engagement with the reciprocating lead screw 16, the rotation of the reciprocating lead screw 16 causes the drive rack 17 to reciprocate horizontally at the lower end of the mounting seat 2. When the drive rack 17 moves, it interacts with the transmission gear 18, and the transmission gear 18 rotates accordingly. The transmission gear 18 is fixedly sleeved with the swivel ring 13, so the transmission gear 18 drives the swivel ring 13 to rotate. Subsequently, the swivel ring 13 winds the lifting rope 12, driving the connected lifting rope 12 to move on the lifting wheel 11. Since the lower end of the lifting rope 12 is fixedly wound inside the fixed ring 7 and is pressed by the connecting bolt 27, the position of the lifting rope 12 is fixed. At this time, the lifting rope 12 pulls the fixed ring 7 upward, causing the protection component to unfold;

[0055] While the protection component is unfolding, the sleeve plate 22 fixedly sleeved with it rotates accordingly. The sleeve plate 22 drives the guide plate 20 to move through the elastic telescopic rod 21. The guide plate 20 moves along the outer wall of the support ring 9, causing the air curtain machine 19 to revolve reciprocally around the support ring 9. At this time, when the air curtain machine 19 operates, it blows out air, forming an air curtain during the unfolding process of the protection component to prevent external water vapor from entering the interior of the protection component. The elastic telescopic rod 21 can perform a certain telescopic adjustment according to the rotation of the swivel ring 13 to ensure that the guide plate 20 and the air curtain machine 19 can move smoothly around the support ring 9, effectively blocking water vapor;

[0056] Finally, when the protection component is fully unfolded, the pressure sensor 25 on the top of the sealing ring 6 is pressed by the pressing block 23, and transmits a pressure signal to the single-chip microcomputer 10. After receiving the signal, the single-chip microcomputer 10 controls the winding protection mechanism and the blowing and rain-proof mechanism to stop working. At this time, the protection component hermetically covers and protects the substation base body, realizing automatic rain-proof protection control.
