Description

Technical Field

[0001] The invention relates to the technical field of oil level gauges, in particular to an oil level gauge for oil filling equipment in a transformer substation with a tilt monitoring structure. Background Art

[0002] In conventional substations, oil-filled equipment occupies a dominant position. For example, oil-immersed transformers, current transformers, voltage transformers, etc. are all oil-immersed. The insulating oil inside is the main insulating part of the equipment, playing a key role in insulation, cooling and arc extinguishing. Insulating oil is the key to ensure the safe and stable operation of oil-filled equipment. The oil level is an important indicator for determining the safe and stable operation of oil-filled equipment. The oil level indicating devices of oil-filled equipment are mainly oil level windows and mechanical oil level gauges. The oil level detection relies on manual inspection. In order to realize real-time monitoring of the oil level, the oil level gauge designed in this paper adopts laser ranging to measure the height of the oil tank liquid level to realize the detection of the oil tank liquid level.

[0003] The oil level gauge uses laser to measure distance. During the distance measurement process, when the oil tank of the substation's oil filling equipment tilts due to a malfunction, the oil level gauge will work abnormally. When the tilt occurs, the oil level gauge will also tilt. However, at this time, the liquid level in the tank is always parallel to the horizontal plane. It is impossible to promptly alert the inspection personnel to the abnormal measurement status, resulting in monitoring errors. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] An oil level gauge for oil filling equipment in a substation with an inclination monitoring structure, comprising:

[0006] A connecting mechanism, the connecting mechanism being used to connect the oil tank of the oil filling device so that the oil level gauge is connected to the oil tank of the oil filling device of the charging station;

[0007] A sealing mechanism, the sealing mechanism being mounted on the top of the connecting mechanism, and a fixing cylinder being fixedly mounted on the top of the sealing mechanism;

[0008] A laser rangefinder, the laser rangefinder being installed inside the fixed barrel;

[0009] A wireless transmitter is mounted on the top of the fixed cylinder and is electrically connected to the laser rangefinder;

[0010] The inner wall of the fixed cylinder is fixedly mounted with an outer support bracket, and the inner wall of the outer support bracket is fixedly mounted with an arc slot cover, the inner wall of the arc slot cover is an arc with a concave center position, the outer side of the laser rangefinder is fixedly mounted with an inner arc ring, the outer side of the inner arc ring is an arc with a convex center position, the outer side of the inner arc ring is slidably fitted with the inner wall of the arc slot cover, and the inner arc ring can rotate a certain angle on the inner wall of the arc slot cover, the bottom of the outer side of the laser rangefinder is fixedly mounted with a counterweight ring, the bottom of the inner wall of the fixed cylinder is fixedly mounted with a cone cover disk, the inner wall of the cone cover disk is fixedly mounted with an inner baffle, a circular groove is provided at the center position of the top of the inner baffle, and the circular groove of the inner baffle cooperates with the laser rangefinder, and the oil level gauge as a whole moves with the oil There is an inclination angle between the inclination of the tank and the horizontal plane. At this time, the counterweight ring and the laser rangefinder, under the action of gravity, drive the inner arc ring to slide inside the arc groove cover, so that the laser rangefinder is always perpendicular to the horizontal plane inside the fixed cylinder. When the angle of inclination affects the measurement accuracy of the oil in the tank, the circular groove of the inner baffle is no longer directly below the laser rangefinder due to the inclination, blocking the laser rangefinder from measuring the oil level in the tank, causing the measurement data of the laser rangefinder to change drastically. At this time, the data transmitted to the detection cloud platform via the wireless transmitter changes significantly, reminding the detection personnel of the abnormality of the oil monitoring status. When the position of the laser rangefinder is perpendicular to the horizontal plane, the circular groove of the inner baffle is located directly below the laser rangefinder.

[0011] Preferably, the outer diameter of the cone cover disk gradually decreases from top to bottom, and an arc convex ring is fixedly installed on the end of the cone cover disk away from the fixed cylinder. The cone cover disk cooperates with the arc convex ring. During the detection process, more volatile oil is contacted by the cone cover disk, so that the oil is gathered at the bottom of the cone cover disk. After the oil is gathered to a certain extent, it is guided to the position of the arc convex ring through the convex strips at the bottom, so that the oil accumulates at the position of the arc convex ring and drips along the bottom of the arc convex ring. The arc convex ring cooperates with the circular groove of the inner baffle plate to avoid oil accumulation directly below the laser rangefinder, resulting in erroneous measurement results. The bottom of the cone cover disk is evenly provided with convex strips, and the bottom of the inner baffle plate is a conical surface with an upward convex center position.

[0012] Preferably, the sealing mechanism includes an inner sliding warehouse, the upper and lower sides of the inner sliding warehouse are provided with through grooves, and the through grooves on the upper and lower sides of the inner sliding warehouse are fixedly installed with fixed tubes, the bottom end of the fixed tube is fixedly connected to the top of the fixed tube, the outer side of the inner sliding warehouse is fixedly installed with an end plate, the center position of the outer side of the end plate is provided with a rotation groove, and the rotation groove of the end plate is rotatably installed. By rotating the threaded tube, the screw drives the inner sealing block to move inside the inner sliding warehouse, thereby realizing the connection and disconnection of the path between the laser rangefinder and the oil tank. When the laser rangefinder or wireless transmitter needs to be disassembled, the path can be closed by the inner sealing block, and the oil tank can be sealed in a disassembled manner, so that the oil level gauge can be replaced and repaired in a live state when it fails, avoiding power outages and power supply losses. The inner wall of the threaded tube is provided with threads, and the inner wall of the inner sliding warehouse is slidably installed with an inner sealing block.

[0013] The top of the inner seal block is provided with a circular groove, and the inner sliding disc is slidably installed at the circular groove of the inner seal block, and an inner gasket is fixedly installed between the top of the inner sliding disc and the inner wall of the inner seal block, and the inner gasket is made of rubber material.

[0014] Preferably, the connecting mechanism includes a threaded barrel, a ring groove disk is fixedly installed on the bottom of the outer side of the threaded barrel, a ring groove is opened on the top of the ring groove disk, and a sealing gasket ring is clamped at the ring groove of the ring groove disk, the top of the ring groove disk and the top of the sealing gasket ring are tightly fitted with the inner wall of the oil tank of the oil filling equipment during installation, a threaded groove is opened on the top of the outer side of the threaded barrel, and the outer side of the threaded barrel is threadedly connected to an outer cover barrel, and an outer ring cover is fixedly installed on the outer side of the outer cover barrel.

[0015] Preferably, an inner sliding ring is slidably installed at the bottom of the outer side of the outer cover tube, and the outer side of the ring gasket is sealed again through the inner sliding ring and the rubber gasket. During installation, the inner sliding ring compresses the rubber gasket into an annular shape after contacting the oil tank, wraps the ring gasket inside, protects the inner rubber ring gasket, blocks the impact of foreign objects, and causes damage to the ring gasket, and assists the cooperation between the ring gasket and the sealing gasket to improve the sealing performance of the connection position with the oil tank. The inner wall of the outer ring cover is clamped with a rubber gasket, and the bottom of the rubber gasket is fixedly connected to the top of the inner sliding ring. A ring clamping groove is opened at the bottom of the outer cover tube, and a ring gasket is clamped at the ring clamping groove of the outer cover tube. The ring gasket is made of rubber material, and a limiting ring is fixedly installed on the inner wall of the outer cover tube. The bottom of the limiting ring fits tightly with the top of the threaded tube.

[0016] The present invention provides an oil level gauge for substation oil filling equipment with a tilt monitoring structure. It has the following beneficial effects:

[0017] 1. The oil level gauge for substation oil filling equipment with an inclination monitoring structure cooperates with the laser rangefinder through the circular groove of the inner baffle. The oil level gauge as a whole appears inclination with the horizontal plane as the oil tank tilts. At this time, the counterweight ring and the laser rangefinder drive the inner arc ring to slide inside the arc groove cover under the action of gravity, so that the laser rangefinder is always perpendicular to the horizontal plane inside the fixed cylinder. When the inclination angle affects the measurement accuracy of the oil in the oil tank, the circular groove of the inner baffle is no longer directly below the laser rangefinder due to its inclination, blocking the laser rangefinder from measuring the oil level in the oil tank, causing the measurement data of the laser rangefinder to change drastically. At this time, the data transmitted to the detection cloud platform through the wireless transmitter changes significantly, reminding the detection personnel of the abnormal oil monitoring status.

[0018] 2. The oil level gauge for substation oil filling equipment with an inclination monitoring structure cooperates with the conical cover plate and the arc convex ring. During the detection process, the conical cover plate contacts more volatile oil, causing the oil to gather at the bottom of the conical cover plate. After the oil gathers to a certain extent, the convex strips at the bottom are used to guide the oil to the position of the arc convex ring, so that the oil accumulates at the position of the arc convex ring and drips along the bottom of the arc convex ring. The arc convex ring cooperates with the circular groove of the inner baffle plate to prevent the accumulation of oil from appearing directly below the laser rangefinder, resulting in erroneous measurement results.

[0019] 3. The oil level gauge for substation oil filling equipment with an inclination monitoring structure rotates the threaded tube to make the screw drive the inner sealing block to move inside the inner sliding bin, thereby realizing the connection and disconnection of the path between the laser rangefinder and the oil tank. When the laser rangefinder or wireless transmitter needs to be disassembled, the path can be closed by the inner sealing block, and the oil tank can be sealed during disassembly, so that the oil level gauge can be replaced and repaired in a live state when it fails, avoiding power outages and power loss.

[0020] 4. The oil level gauge for substation oil filling equipment with an inclination monitoring structure cooperates with the inner sliding plate through the circular groove of the inner sealing block. When monitoring is stopped and the oil tank is closed, the pressure in the oil tank can be transmitted to the inner gasket through the inner sliding plate. Utilizing the characteristics of the rubber material of the inner gasket, when the pressure in the oil tank increases, the pressure is buffered to ensure safety in the sealed state and avoid accidents caused by high pressure in the oil tank.

[0021] 5. The oil level gauge for the substation oil filling equipment with the inclination monitoring structure is re-sealed on the outside of the ring gasket through the inner sliding ring and the rubber gasket. During installation, after the inner sliding ring contacts the oil tank, it compresses the rubber gasket to change its shape and wraps the ring gasket inside, thereby protecting the inner rubber ring gasket, preventing foreign body impact and causing damage to the ring gasket, and assisting the cooperation between the ring gasket and the sealing gasket to improve the sealing performance of the connection position with the oil tank.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0035] An oil level gauge for oil filling equipment in a substation with an inclination monitoring structure, comprising:

[0036] Connecting mechanism 3, connecting mechanism 3 is used to connect the oil tank of the oil filling device, so that the oil level gauge is connected to the oil tank of the oil filling device of the charging station;

[0037] The sealing mechanism 2 is mounted on the top of the connecting mechanism 3, and a fixing cylinder 4 is fixedly mounted on the top of the sealing mechanism 2;

[0038] A laser rangefinder 5 is installed inside the fixed tube 4;

[0039] A wireless transmitter 1 is mounted on the top of the fixed cylinder 4 and is electrically connected to the laser rangefinder 5;

[0040] The inner wall of the fixed cylinder 4 is fixedly installed with an outer support frame 7, and the inner wall of the outer support frame 7 is fixedly installed with an arc slot cover 6. The inner wall of the arc slot cover 6 is an arc with a depression in the center. The outer side of the laser rangefinder 5 is fixedly installed with an inner arc ring 8. The outer side of the inner arc ring 8 is an arc with a convex center. The outer side of the inner arc ring 8 is slidably adapted to the inner wall of the arc slot cover 6. During the monitoring process, the laser rangefinder 5 uses the counterweight ring 9 to make the center of the laser rangefinder 5 and the counterweight ring 9 as a whole below the inner arc ring 8 and the arc slot cover 6. When the oil tank of the oil filling equipment of the substation is accidentally hit and tilted, due to the connection between the connecting mechanism 3 and the oil tank, the oil level gauge as a whole has an inclination angle with the horizontal plane as the oil tank tilts. At this time, the counterweight ring 9 and the laser rangefinder 5 drive the inner arc ring 8 to slide inside the arc slot cover 6 under the action of gravity, so that the laser rangefinder 5 is always inside the fixed cylinder 4. Perpendicular to the horizontal plane, when the inclination angle affects the measurement accuracy of the oil in the fuel tank, the circular groove of the inner baffle 10 is no longer directly below the laser rangefinder 5 due to the inclination, blocking the laser rangefinder 5 from measuring the oil level in the fuel tank, causing the measurement data of the laser rangefinder 5 to change drastically. At this time, the data transmitted to the detection cloud platform through the wireless transmitter 1 changes significantly, reminding the detection personnel of the abnormality of the oil monitoring status, and the inner arc ring 8 can rotate a certain angle on the inner wall of the arc groove cover 6. A counterweight ring 9 is fixedly installed at the bottom of the outer side of the laser rangefinder 5, and a cone cover disk 11 is fixedly installed at the bottom of the inner wall of the fixed cylinder 4. An inner baffle 10 is fixedly installed on the inner wall of the cone cover disk 11. A circular groove is opened at the center of the top of the inner baffle 10. When the position of the laser rangefinder 5 is perpendicular to the horizontal plane, the circular groove of the inner baffle 10 is located directly below the laser rangefinder 5.

[0041] The outer diameter of the conical cover disk 11 gradually decreases from top to bottom, and an arc convex ring 12 is fixedly installed on the end of the conical cover disk 11 away from the fixed cylinder 4. When the laser rangefinder 5 monitors the oil level in the fuel tank in real time, when the oil inside the fuel tank evaporates, the oil evaporates through the conical cover disk 11. When the oil evaporates along the path between the laser rangefinder 5 and the fuel tank, the bottom of the conical cover disk 11 contacts the evaporated oil, so that most of the evaporated oil gathers at the bottom of the conical cover disk 11. When the volatile oil gathers to a certain extent, the oil that has gathered to a certain extent flows to the position of the arc convex ring 12 through the guidance of the convex strips and the gravity of the oil-collecting oil itself, and drips back to the fuel tank along the bottom of the arc convex ring 12. The bottom of the conical cover disk 11 is evenly provided with convex strips, and the bottom of the inner baffle plate 10 is a conical surface with a center position convex upward.

[0042] The second embodiment, based on the first embodiment, see Figures 6 to 8As shown, the sealing mechanism 2 includes an inner sliding bin 21, and through grooves are provided on the upper and lower sides of the inner sliding bin 21, and fixed tubes 22 are fixedly installed at the through grooves on the upper and lower sides of the inner sliding bin 21. The bottom end of the fixed cylinder 4 is fixedly connected to the top of the fixed tube 22, and an end plate 23 is fixedly installed on the outer side of the inner sliding bin 21. When it is necessary to measure the liquid level in the oil tank through the laser rangefinder 5, the worker rotates the threaded tube 26 with a wrench to rotate the threaded tube 26 on the inner wall of the end plate 23. Through the threaded connection between the threaded tube 26 and the screw 25, the screw 25 drives the inner sealing block 27 to move inside the inner sliding bin 21, so that the inner sealing block 27 is away from the through groove position of the inner sliding bin 21, opening the path between the laser rangefinder 5 and the oil tank. A rotating groove is provided at the center position of the outer side of the end plate 23, and a threaded tube 26 is rotatably installed at the rotating groove of the end plate 23. The inner wall of the threaded tube 26 is provided with threads, and the inner sealing block 27 is slidably installed on the inner wall of the inner sliding bin 21.

[0043] A screw 25 is fixedly installed at the center position of the inner sealing block 27 near the end plate 23. The end of the screw 25 away from the inner sealing block 27 passes through the end plate 23 and extends to the other side. The end of the screw 25 away from the inner sealing block 27 is fixedly installed with a limit block 24. The outer side of the screw 25 is threadedly connected to the inner wall of the threaded tube 26. A smooth groove is provided at the bottom of the inner sealing block 27. When a faulty laser rangefinder 5 or wireless transmitter 1 needs to be repaired or replaced, the worker can also use a wrench to turn the threaded tube 26. 6. The inner sealing block 27 is made to slide inside the inner sliding bin 21 so that the inner sealing block 27 is located between the through grooves, closing the passage between the oil tank and the laser rangefinder 5 and sealing the oil tank so that workers can dismantle the laser rangefinder 5 when the substation is energized. A circular groove is provided on the top of the inner sealing block 27, and an inner sliding disc 29 is slidably installed on the circular groove of the inner sealing block 27. An inner gasket 28 is fixedly installed between the top of the inner sliding disc 29 and the inner wall of the inner sealing block 27. The inner gasket 28 is made of rubber material.

[0044] The third embodiment, based on the first and second embodiments, see Figures 9 and 10As shown, the connecting mechanism 3 includes a threaded barrel 34, a ring groove disc 33 is fixedly installed at the bottom of the outer side of the threaded barrel 34, a ring groove is provided on the top of the ring groove disc 33, and a sealing gasket ring 39 is clamped at the ring groove of the ring groove disc 33. The top of the ring groove disc 33 and the top of the sealing gasket ring 39 are tightly fitted with the inner wall of the oil tank of the oil filling device during installation. A threaded groove is provided on the top of the outer side of the threaded barrel 34. During installation, the ring groove disc 33 is screwed together with the outer cover barrel 31 through the threaded connection between the threaded barrel 34 and the outer cover barrel 31. The distance between the threaded cylinder 34 and the outer cover cylinder 31 gradually decreases, and the oil tank is clamped on both sides of the inner and outer sides of the installation port of the oil tank. At the same time, in the process of clamping and fixing, the distance between the sealing gasket ring 39 and the ring gasket 38 gradually decreases. After the sealing gasket ring 39 and the ring gasket 38 contact the oil tank, the rubber deformation under the contact pressure increases the fit between the oil tank and the sealing of the connection position, and the outer side of the threaded cylinder 34 is threadedly connected to the outer cover cylinder 31, and the outer side of the outer cover cylinder 31 is fixedly installed with the outer ring cover 32.

[0045] An inner sliding ring 37 is slidably installed on the bottom of the outer side of the outer cover tube 31, and a rubber gasket 36 is clamped on the inner wall of the outer ring cover 32. The bottom of the rubber gasket 36 is fixedly connected to the top of the inner sliding ring 37. A ring clamping groove is provided at the bottom of the outer cover tube 31. Before the ring gasket 38 and the sealing gasket 39 are tightly fitted into the oil tank, the bottom end of the inner sliding ring 37 first contacts the oil tank, and in the subsequent tightening process, the inner sliding ring 37 slides on the outside of the outer cover tube 31, compressing the rubber gasket 36 to deform, forming protection on the outside of the ring gasket 38, and a ring gasket 38 is clamped at the ring clamping groove of the outer cover tube 31. The ring gasket 38 is made of rubber material. A limit ring 35 is fixedly installed on the inner wall of the outer cover tube 31, and the bottom of the limit ring 35 is tightly fitted with the top of the threaded tube 34.

[0046] During use, the oil level gauge is connected to the oil tank of the oil filling equipment through the connecting mechanism 3 of the oil level gauge, and the sealing mechanism 2 is adjusted by a wrench so that the sealing mechanism 2 releases the seal between the laser rangefinder 5 and the oil tank. During operation, the laser rangefinder 5 measures the oil level in the oil tank and transmits the data to the wireless transmitter 1 through an electrical signal, so that the wireless transmitter 1 converts the electrical signal into an electromagnetic wave and transmits it to the detection cloud platform, thereby realizing real-time monitoring of the oil level. When the laser rangefinder 5 fails and needs to be replaced and repaired, the worker adjusts the sealing mechanism 2 with a wrench so that the sealing mechanism 2 seals the path between the oil tank and the laser rangefinder 5, and then removes the laser rangefinder 5 by disassembling the fixing tube 4, thereby realizing replacement and repair of the oil level gauge in a live state when it fails, thereby avoiding power outages and power loss.

[0047] During the process of the laser rangefinder 5 monitoring the oil level in the oil tank in real time, when the oil inside the oil tank evaporates, the oil evaporates through the cone cover 11. When the oil moves along the path between the laser rangefinder 5 and the oil tank, the bottom of the cone cover 11 contacts the evaporated oil, causing most of the evaporated oil to gather at the bottom of the cone cover 11. When the evaporated oil gathers to a certain extent, the oil that has gathered to a certain extent flows to the position of the arc convex ring 12 through the guidance of the convex strips and the gravity of the oil gathering oil itself, and drips back to the oil tank along the bottom of the arc convex ring 12. At the same time, during the monitoring process, the laser rangefinder 5 uses the counterweight ring 9 to make the center of the laser rangefinder 5 and the counterweight ring 9 as a whole below the inner arc ring 8 and the arc slot cover 6. When the oil filling equipment of the substation is filled with oil, the oil will flow to the bottom of the cone cover 11. When the tank is accidentally hit and tilted, due to the connection between the connecting mechanism 3 and the oil tank, the oil level gauge as a whole will have an inclination angle with the horizontal plane as the oil tank tilts. At this time, the counterweight ring 9 and the laser rangefinder 5 drive the inner arc ring 8 to slide inside the arc groove cover 6 under the action of gravity, so that the laser rangefinder 5 is always perpendicular to the horizontal plane inside the fixed cylinder 4. When the angle of inclination affects the measurement accuracy of the oil in the oil tank, the circular groove of the inner baffle 10 is no longer directly below the laser rangefinder 5 due to the tilt, blocking the laser rangefinder 5 from measuring the oil level in the oil tank, causing the measurement data of the laser rangefinder 5 to change drastically. At this time, the data transmitted to the detection cloud platform through the wireless transmitter 1 changes significantly, reminding the detection personnel of the abnormality of the oil monitoring status.

[0048] In the sealing mechanism 2, when it is necessary to measure the liquid level in the oil tank by means of the laser rangefinder 5, the worker rotates the threaded tube 26 with a wrench so that the threaded tube 26 rotates on the inner wall of the end plate 23. Through the threaded connection between the threaded tube 26 and the screw 25, the screw 25 drives the inner sealing block 27 to move inside the inner sliding bin 21, so that the inner sealing block 27 is away from the through-slot position of the inner sliding bin 21, thereby opening the path between the laser rangefinder 5 and the oil tank. When in use, when it is necessary to repair or replace the faulty laser rangefinder 5 or wireless transmitter 1, the worker can also rotate the threaded tube 26 with a wrench so that the inner sealing block 27 slides inside the inner sliding bin 21, so that the inner sealing block 27 is between the through-slots, thereby closing the path between the oil tank and the laser rangefinder 5 and sealing the oil tank, so that the worker can disassemble the laser rangefinder 5 when the substation is energized.

[0049] In the connecting mechanism 3, during installation, the threaded connection between the threaded cylinder 34 and the outer cover cylinder 31 is used. During the installation process, the distance between the ring groove disk 33 and the outer cover cylinder 31 is gradually reduced, and the oil tank is clamped on both sides of the installation port of the oil tank. At the same time, during the clamping and fixing process, the distance between the sealing gasket 39 and the ring gasket 38 is gradually reduced. After the sealing gasket 39 and the ring gasket 38 contact the oil tank, the rubber deformation under the contact pressure increases the fit between the oil tank and the sealing position, and the sealing of the connection position is strengthened. Before the ring gasket 38 and the sealing gasket 39 are tightly fitted to the oil tank, the bottom end of the inner sliding ring 37 first contacts the oil tank, and in the subsequent tightening process, the inner sliding ring 37 slides on the outside of the outer cover cylinder 31, compressing the rubber gasket 36 to deform and form protection on the outside of the ring gasket 38.
