Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figure 1-8 As shown, the present invention provides a test device for a GIS-based hydrogen-blended natural gas gathering and transportation system, including a control cabinet body 1 and a transfer mechanism 2. The transfer mechanism 2 is provided with positioning mechanisms 3 on both sides, and a reinforcement mechanism 4 that works in conjunction with the positioning mechanisms 3 is provided on the transfer mechanism 2. A fixing mechanism 5 is fixedly installed at the top of the transfer mechanism 2, and the control cabinet body 1 and the fixing mechanism 5 are detachably connected. An auxiliary mechanism 6 that works in conjunction with the control cabinet body 1 is provided in the inner cavity of the fixing mechanism 5.

[0028] The transfer mechanism 2 includes a transfer base plate 21. Universal casters 22 are fixedly installed at the four corners of the transfer base plate 21 on the side away from the control cabinet body 1. Side connecting plates 23 are fixedly connected to both ends of the transfer base plate 21. Z-shaped push rods 24 are symmetrically arranged on the opposite sides of the side connecting plates 23. Anti-slip bushings 25 are fixedly fitted on the end of the Z-shaped push rods 24 away from the side connecting plates 23. The anti-slip bushings 25 can increase friction and facilitate operation.

[0029] By adopting the above technical solution, when in use, the corresponding two Z-shaped push rods 24 can be pushed, which can be used in conjunction with the use of casters 22 to move the transfer base plate 21 and the side connecting plate 23, thereby moving the control cabinet body 1 until it is moved to a suitable position and then the push rods 24 are stopped.

[0030] The positioning mechanism 3 includes a U-shaped positioning plate 31, which is fixedly connected to the side connecting plate 23. A threaded hole 32 is provided through the middle of the U-shaped positioning plate 31, and a threaded rod 33 is threadedly inserted into the threaded hole 32. A connecting through hole 26 is provided through the side connecting plate 23 to cooperate with the threaded rod 33. The threaded rod 33 movably passes through the connecting through hole 26 and is rotatably connected to a positioning base block 34 at its end. A first rotating wheel 36 is fixedly connected to the end of the threaded rod 33 away from the positioning base block 34, and a drive rocker arm 37 is rotatably inserted into the first rotating wheel 36. The cooperation between the first rotating wheel 36 and the drive rocker arm 37 provides convenience for the rotation adjustment of the threaded rod 33. A symmetrically distributed guide slide rod 35 is fixedly installed at the top of the positioning base block 34. A symmetrically arranged guide through hole 27 is provided through the side connecting plate 23, and the guide slide rod 35 is slidably inserted into the guide through hole 27.

[0031] By adopting the above technical solution, the two drive rockers 37 can be rotated in sequence during use, thereby driving the corresponding first rotating wheel 36 to rotate, which in turn drives the corresponding threaded rod 33 to rotate. Furthermore, in conjunction with the use of the guide slide rod 35 and the guide through hole 27, the corresponding positioning base block 34 can be moved to the side away from the side connecting horizontal plate 23 until the positioning base block 34 is in close contact with the ground.

[0032] The reinforcement mechanism 4 includes side crossbars 41, which are fixedly connected to the positioning base block 34. The side crossbars 41 are symmetrically distributed, and each opposite end of an adjacent side crossbar 41 is fixedly connected to a fixing collar 42. A reinforcement cylinder 43 is fixedly inserted into the fixing collar 42. Symmetrically arranged sliding holes 28 are provided through the side crossbar 23, and the reinforcement cylinder 43 can be slidably inserted into the sliding holes 28. A rubber sealing ring 44 is fixedly connected to the bottom end of the reinforcement cylinder 43. U-shaped positioning The plate 31 has symmetrically arranged fixed through holes 38, and a vertical mounting rod 45 is fixedly inserted into the fixed through hole 38. The top of the reinforcing cylinder 43 has a sliding through hole 46, and the vertical mounting rod 45 slides through the sliding through hole 46 and is fixedly connected to the end of the vertical mounting rod 45. The sealing piston 47 is movably inserted into the reinforcing cylinder 43. The working principle of the sealing piston 47 and the reinforcing cylinder 43 is the same as that of the syringe. This is the prior art and will not be described in detail here.

[0033] By adopting the above technical solution, when the positioning base block 34 moves away from the side connecting horizontal plate 23, it will drive the corresponding side connecting horizontal bar 41 to move, thereby driving the corresponding fixing collar 42 to move, and then driving the corresponding reinforcing cylinder 43 to move. At this time, the sealing piston 47 will slide along the inner wall of the reinforcing cylinder 43, thereby allowing the air at the upper end of the sealing piston 47 to be discharged through the sliding through hole 46. When the sealing piston 47 is in close contact with the ground, as the reinforcing cylinder 43 moves downward, the rubber sealing ring 44 can be tightly adsorbed onto the ground with the corresponding reinforcing cylinder 43. When the positioning base block 34 is in close contact with the ground, the reinforcing cylinder 43 stops moving.

[0034] The fixing mechanism 5 includes a fixed base frame 51, which is fixedly connected to the transfer base plate 21. A vertical rotating rod 52 is rotatably inserted into the middle of the bottom end of the fixed base frame 51. A connecting hole 29 is opened through the middle of the transfer base plate 21, and the vertical rotating rod 52 movably passes through the connecting hole 29 and is fixedly connected to a first bevel gear 53 at its end. A return torsion spring 54 is fixedly installed at the top of the first bevel gear 53. The return torsion spring 54 is movably sleeved on the vertical rotating rod 52, and the top of the return torsion spring 54 is fixedly connected to the fixed base frame 51. A transverse rotating rod 55 is rotatably inserted into the bottom end of the transfer base plate 21, and a second bevel gear 56 is fixedly connected to the end of the transverse rotating rod 55. The second bevel gear 56 and the first bevel gear... The bottom of the transfer base plate 21 is fixedly mounted with a rotating support 515, and the transverse rotating rod 55 is rotatably inserted into the rotating support 515. The rotating support 515 ensures the stable rotation of the transverse rotating rod 55. The end of the transverse rotating rod 55 away from the second bevel gear 56 is fixedly connected to a second rotating wheel 516. The second rotating wheel 516 facilitates the adjustment of the rotation of the transverse rotating rod 55, and the outer wall of the second rotating wheel 516 is covered with an anti-slip texture. The top of the vertical rotating rod 52 is fixedly fitted with a drive rotating plate 57, and both ends of the drive rotating plate 57 are provided with drive through slots 58. Two transverse sliding plates 59 are slidably installed at the bottom of the inner cavity of the fixed base frame 51. A drive guide post 510 is rotatably inserted into the end of the slide plate 59 near the drive rotating plate 57. The drive guide post 510 is movably inserted into the drive through slot 58, and a limiting collar 511 is fixedly sleeved on the top of the drive guide post 510. A fixed slide plate 512 is fixedly connected to the end of the transverse slide plate 59 away from the drive rotating plate 57, and symmetrically arranged fixed insert rods 513 are fixedly installed on the opposite sides of the fixed slide plate 512. A fixed slot 514 is opened at the top of the fixed base frame 51. A fixed plug 11 is fixedly connected to the bottom of the control cabinet body 1, and symmetrically distributed fixed plug holes 12 are opened through both sides of the fixed plug 11. The fixed plug 11 can be slidably inserted into the fixed slot 514, and the fixed plug rods 513... The auxiliary mechanism 6, which can be slidably inserted into the fixed socket 12, includes a first U-shaped block 61. The first U-shaped block 61 is fixedly installed on the opposite side of the fixed slide plate 512 and is symmetrically distributed. A first T-shaped block 62 is rotatably inserted into the inner side of the first U-shaped block 61, and a telescopic sleeve rod 63 is fixedly connected to the first T-shaped block 62. A second T-shaped block 64 is fixedly connected to the end of the telescopic sleeve rod 63, and a second U-shaped block 65 is rotatably sleeved on the second T-shaped block 64. The second U-shaped block 65 is fixedly connected to the inner wall of the fixed base frame 51. A return spring 66 is movably sleeved on the outer side of the telescopic sleeve rod 63, and the two ends of the return spring 66 are fixedly connected to the first T-shaped block 62 and the second T-shaped block 64, respectively.

[0035] By adopting the above technical solution, during use, the user can rotate the second rotating wheel 516, which can drive the transverse rotating rod 55 to rotate, thereby driving the second bevel gear 56 to rotate, and further driving the first bevel gear 53 to rotate. Simultaneously, the rotation of the first bevel gear 53 can drive the vertical rotating rod 52 to rotate, thereby torsion the reset torsion spring 54 and driving the drive rotating plate 57 to rotate. This allows the drive guide post 510 to roll along the corresponding drive through groove 58, causing the transverse sliding plate 59 to move away from the vertical rotating rod 52. This, in turn, drives the two fixed sliding plates 512 to move in opposite directions, further driving the corresponding fixed insert rod 513 to move in opposite directions. Furthermore, the movement of the fixed sliding plate 512 will drive the corresponding first U-shaped block 61 to move, thus coordinating with the use of the second U-shaped block 65 to drive the first T-shaped block 62 and the extension... The telescopic rod 63 and the second T-block 64 rotate, which causes the telescopic rod 63 to retract and compress the corresponding return spring 66. When the fixed insert rod 513 moves into the fixed base frame 51, the second rotating wheel 516 stops rotating. Then, the user can insert the fixed insert block 11 of the control cabinet body 1 into the fixed slot 514 and release the second rotating wheel 516. At this time, the return torsion spring 54 will drive the vertical rotating rod 52 to return through the first bevel gear 53, which will drive the drive rotating plate 57 to return. Then, the fixed sliding plate 512 will be driven to return through the drive guide post 510 and the horizontal sliding plate 59. At the same time, the return spring 66 will work with the use of the first T-block 62 and the second T-block 64 to drive the first U-block 61 to return, which will drive the fixed sliding plate 512 to return, which will drive the fixed insert rod 513 to return and insert it into the corresponding fixed socket 12.

[0036] Working principle: In use, the user can rotate the second rotating wheel 516, which drives the horizontal rotating rod 55 to rotate, which in turn drives the second bevel gear 56 to rotate, and further drives the first bevel gear 53 to rotate. At the same time, the rotation of the first bevel gear 53 drives the vertical rotating rod 52 to rotate, which in turn twists the return spring 54 and drives the drive rotating plate 57 to rotate. This causes the drive guide post 510 to roll along the corresponding drive through groove 58, which causes the horizontal sliding plate 59 to move away from the vertical rotating rod 52. This causes the two fixed sliding plates 512 to move in opposite directions, and further causes the corresponding fixed insert rod 513 to move in opposite directions. At the same time, the movement of the fixed sliding plate 512 will drive the corresponding first U-shaped block 61 to move, which, in conjunction with the use of the second U-shaped block 65, drives the first T-shaped block 62 and the telescopic sleeve rod. The rotation of the second T-block 64 and the telescopic sleeve 63 causes the telescopic sleeve 63 to retract and compress the corresponding return spring 66. When the fixed insert 513 moves into the fixed base frame 51, the rotation of the second rotating wheel 516 stops. Then, the user can insert the fixed insert 11 of the control cabinet body 1 into the fixed slot 514 and release the second rotating wheel 516. At this time, the return torsion spring 54 will drive the vertical rotating rod 52 to return through the first bevel gear 53, thereby driving the drive rotating plate 57 to return, and then driving the fixed sliding plate 512 to return through the drive guide post 510 and the horizontal sliding plate 59. At the same time, the return spring 66 will cooperate with the use of the first T-block 62 and the second T-block 64 to drive the first U-block 61 to return, thereby driving the fixed sliding plate 512 to return, and then driving the fixed insert 513 to return and insert it into the corresponding fixed socket 12.

[0037] The user can then push the two corresponding Z-shaped push rods 24, which, in conjunction with the use of the casters 22, can move the transfer base plate 21 and the side connecting plate 23, thereby moving the control cabinet body 1 until it is moved to the appropriate position and then the user stops pushing the Z-shaped push rods 24.

[0038] The user can then rotate the two drive rockers 37 in sequence, which will drive the corresponding first rotating wheel 36 to rotate, which will then drive the corresponding threaded rod 33 to rotate. Furthermore, with the use of the guide slide rod 35 and the guide through hole 27, the corresponding positioning block 34 can be moved away from the side connecting horizontal plate 23 until the positioning block 34 is in close contact with the ground.

[0039] During this period, when the positioning base block 34 moves away from the side connecting horizontal plate 23, it will drive the corresponding side connecting horizontal bar 41 to move, thereby driving the corresponding fixing collar 42 to move, and then driving the corresponding reinforcing cylinder 43 to move. At this time, the sealing piston 47 will slide along the inner wall of the reinforcing cylinder 43, thereby allowing the air at the upper end of the sealing piston 47 to be discharged through the sliding through hole 46. When the sealing piston 47 is in close contact with the ground, as the reinforcing cylinder 43 moves downward, the rubber sealing ring 44 can be tightly adsorbed onto the ground with the corresponding reinforcing cylinder 43. When the positioning base block 34 is in close contact with the ground, the reinforcing cylinder 43 stops moving.

[0040] During subsequent use, users can conveniently carry out disassembly, relocation and fixing operations of the control cabinet body 1 by following the above steps.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
