Description

Technical Field

[0001] This invention belongs to the field of storage equipment, and specifically relates to a transformer oil sample storage box. Background Technology

[0002] During the operation of a transformer, impurities such as gas are generated. Therefore, it is necessary to frequently extract oil samples from the transformer and analyze them to determine whether there is a fault inside the transformer.

[0003] Currently, transformer oil samples are collected by using a sampling syringe to extract the oil, attaching relevant labels, placing it in a special foam box for shock protection, and then neatly placing it in a sampling box before being taken back to the laboratory for testing and analysis.

[0004] The process of taking samples and placing them into the sampling box is cumbersome. For example, labeling, placing them in a special foam box and arranging them neatly all prolong the sampling efficiency of transformer oil. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a transformer oil sample storage box to solve the problem of low transformer oil sampling efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] A transformer oil sample storage box includes a box body with a cover at the top, and a lifting component located at the bottom of the box body. The number of lifting components is at least two and they are arranged side by side. Each lifting component is provided with at least one protective box, and a drive mechanism for driving the lifting component to move up and down is provided on one side of the lifting component.

[0008] Furthermore, the lifting component includes a base plate, a placement plate located above the base plate, a first connecting rod with its first end rotatably connected to the base plate, and a second connecting rod with its first end rotatably connected to the placement plate. The second end of the first connecting rod is slidably connected to the bottom end of the placement plate, and the second end of the second connecting rod is slidably connected to the upper end of the base plate. The first connecting rod and the second connecting rod are arranged in an X shape and are rotatably connected at their intersection point.

[0009] Furthermore, the drive mechanism is located inside the housing on the side away from the second end of the second link. The drive mechanism includes a third link, a fourth link, and the same number of traction ropes as the base plate. The third link is horizontally positioned and its front end is rotatably connected to the housing. The fourth link is vertically positioned and its bottom end is rotatably connected to the rear end of the third link. The housing is rotatably connected to the cover, and the upper end of the fourth link is rotatably connected to the cover. A guide ring is provided on the side of the base plate near the third link. The first end of the traction rope is fixedly connected to the second end of the second link, and the second end of the traction rope passes through the guide ring and is fixedly connected to the third link.

[0010] Furthermore, the protective box includes a pressure-resistant box, a snap-fit ​​block disposed in the pressure-resistant box, and a writing board rotatably connected to the upper end of the pressure-resistant box.

[0011] Furthermore, the front and top openings of the pressure-resistant box allow the writing board to be rotatably connected to the top of the pressure-resistant box.

[0012] Furthermore, the interlocking block is provided with a placement groove with openings on the front and top, and a flexible snap-fit ​​post is provided on the inner wall of the front side of the placement groove.

[0013] Furthermore, a magnet is embedded at the bottom of the protective box, and a magnetic suction device that matches the magnet is provided on the lifting component.

[0014] Furthermore, fan-shaped elastic fabrics are provided on both sides of the upper end of the box. One end of the elastic fabric is fixedly connected to the upper end of the box, and the other end of the elastic fabric is fixedly connected to the bottom end of the cover.

[0015] Furthermore, the interlocking blocks are made of sponge material.

[0016] Furthermore, a carrying strap is provided on the box.

[0017] The significant beneficial effects achieved by this invention are as follows:

[0018] 1. This invention discloses a transformer oil sample storage box, comprising a box body with a top cover, and lifting components disposed at the bottom of the box body. There are at least two lifting components arranged side-by-side, each with at least one protective box. A drive mechanism for raising and lowering the lifting components is provided on one side of each lifting component. This application utilizes the covered box body to link the drive mechanism, causing multiple lifting components to rise simultaneously, presenting the protective boxes in a stepped manner to the operator. This facilitates the placement and removal of sampling syringes. A writing board is included for easy repetition of writing, eliminating the need for labeling or repeated placement of sampling syringes; they can be directly placed into the corresponding protective boxes. This method is convenient, quick, and efficient, effectively solving the problem of low transformer oil sampling efficiency.

[0019] 2. The lifting mechanism adopts an X-shaped intersecting first and second linkage, which can directly lift and lower under the drive mechanism without the need for electric components. This makes it convenient to operate and eliminates the problem of battery life.

[0020] 3. The drive mechanism can be linked with the cover. When the cover is opened, the lifting component is driven to rise. When the cover is closed, the lifting component automatically returns to its original position. When the lifting component rises and falls, the protective box rises and falls accordingly to expose or retract the sampling syringe.

[0021] 4. The guide ring can limit the trajectory of the traction rope, ensuring that the second link can move stably.

[0022] 5. The flexible snap-fit ​​column facilitates the insertion and removal of samples during laboratory sampling or analysis; while ensuring easy access, the flexible snap-fit ​​column also protects the sampling syringe from collisions.

[0023] 6. The magnet at the bottom of the protective box and the magnetic attachment on the placement plate can stably place the protective box on the placement plate, avoiding the problem of the protective box jumping after being bumped, and avoiding excessive vibration of the sampling syringe.

[0024] 7. The fan-shaped elastic cloth can protect the sides of the box and prevent the sampling syringe from being exposed to direct sunlight.

[0025] 8. The strap design makes it convenient for staff to carry the case. Attached Figure Description

[0059] Example 1

[0060] like Figures 1-5 As shown, a transformer oil sample storage box includes a box body 1 with a cover 19 on the top, and a lifting component fixedly installed at the bottom of the box body 1. The number of lifting components is at least two and they are arranged side by side. Each lifting component is provided with at least one protective box. A drive mechanism for driving the lifting component to lift is provided on one side of the lifting component.

[0061] Among them, the box body 1 is a box body 1 with an open top, and the rear side of the cover 19 is rotatably connected to the rear side of the top of the box body 1.

[0062] The lifting component includes a base plate 2 fixedly connected to the bottom of the housing 1, a placement plate 3 located above the base plate 2, a first connecting rod 4 rotatably connected to the base plate 2 at its first end, and a second connecting rod 5 rotatably connected to the placement plate 3 at its first end. The second end of the first connecting rod 4 is slidably connected to the bottom end of the placement plate 3, and the second end of the second connecting rod 5 is slidably connected to the upper end of the base plate 2. The first connecting rod 4 and the second connecting rod 5 are arranged in an X shape and are rotatably connected at their intersection point.

[0063] The drive mechanism is located inside the housing 1 on the side away from the second end of the second connecting rod 5. There is one drive mechanism, which includes a third connecting rod 6, a fourth connecting rod 7, and the same number of traction ropes 9 as the base plate 2. The third connecting rod 6 is horizontally arranged and its front end is rotatably connected to the front side of the housing 1. The fourth connecting rod 7 is vertically arranged and its bottom end is rotatably connected to the rear end of the third connecting rod 6. The housing 1 is rotatably connected to the cover 19. The upper end of the fourth connecting rod 7 is rotatably connected to the cover 19. Guide rings 8 are fixedly installed on the side of the base plate 2 near the third connecting rod 6. The traction ropes 9 are respectively connected to the base plate 2. The first end of the traction rope 9 is fixedly connected to the second end of the second connecting rod 5. The second end of each traction rope 9 passes through the guide ring 8 and is fixedly connected to the third connecting rod 6.

[0064] The protective box includes a pressure-resistant box 11, a snap-fit ​​block 12 fixedly installed inside the pressure-resistant box 11, and a writing board 10 rotatably connected to the upper end of the pressure-resistant box 11. The protective box is used to place the syringe-shaped sampling container.

[0065] The writing board 10 is an erasable and rewritable board.

[0066] The pressure-resistant box 11 is made of iron. The top and front of the pressure-resistant box 11 are open. The writing board 10 is rotatably connected to the top of the pressure-resistant box 11. The writing board 10 is designed to facilitate the staff to write the corresponding marks. The writing board 10 is rotatably connected to the top of each protective box to correspond to each sampling syringe. The front opening of the pressure-resistant box 11 is designed to facilitate the insertion of the sampling syringe. The writing board 10 is rotatably connected by a torsion spring to facilitate opening and removal and automatic return to its original position.

[0067] The insert block 12 is a sponge block with a placement groove 13. The opening of the placement groove 13 corresponds to the top and front of the pressure-resistant box 11. Flexible locking posts 14 are symmetrically arranged on the inner wall of the front side of the placement groove 13. The placement groove 13 is adapted to the shape of the sampling syringe. The placement groove 13 is used to place the sampling syringe. When the sampling syringe is inserted, it can be directly inserted through the front opening of the placement groove 13. After the sampling syringe enters, it is blocked by the flexible locking post and thus placed stably. When taking it out, the operation is reversed.

[0068] Working principle: Taking a box 1 containing three lifting components as an example, each lifting component has three protective boxes. Initially, the cover 19 of box 1 is closed. When it is necessary to take out the sampling syringe for sampling, the operator opens the cover 19. As the cover 19 opens, the upper end of the fourth connecting rod 7 is rotatably connected to the cover 19, causing the fourth connecting rod 7 to rise with the cover 19. Driven by the fourth connecting rod 7, the rear end of the third connecting rod 6 tilts and rises accordingly. When the third connecting rod 6 tilts and rises, the traction rope 9 fixed to the third connecting rod 6 is also moved, causing the second end of the second connecting rod 5 to move towards the guide ring 8. The placement plate 3 then drives the protective boxes to rise. By fixing the traction rope 9 to the third connecting rod 6... The lifting height of each lifting component is set according to its position, ideally with one-quarter of the sampling syringe protruding after the protective box rises. The inclined third link 6 allows each lifting component to have a different lifting height, ideally with the three lifting components arranged in a stepped shape for easy access. After the protective box rises, the staff can directly remove the sampling syringe. To insert the sampling syringe, simply lift the writing board 10. After sampling, simply close the cover 19. The lifting components will automatically descend under gravity. When the sample is brought back to the laboratory for analysis, the staff can directly remove the protective box for analysis and simply place a new protective box inside the box 1. This facilitates preservation without affecting the remaining sampling work.

[0069] In summary, this application uses a housing 1 with a cover 19 to drive the mechanism, thereby causing multiple lifting components to rise simultaneously and present the protective box in a stepped manner to the staff. This facilitates the staff in picking up and placing the sampling syringes. The writing board 10 facilitates repeated writing, eliminating the need for labels or repeated placement of the sampling syringes. They can be directly placed into the corresponding protective box, which is convenient, quick, and efficient, effectively solving the problem of low efficiency in transformer oil sampling.
