Description

Technical Field

[0001] This invention relates to the field of busbar testing technology, specifically to a busbar tensile testing device based on busbar drain clamp production. Background Technology

[0002] In power plants, substations, and distribution stations, busbars are conductors used to connect multiple electrical circuits (such as generators, transformers, and transmission lines) and to collect, distribute, and transmit electrical energy. They can be thought of as "highway hubs" or "main roads" in the power system. All generated and distributed electricity is first collected here and then distributed to various directions (lines). They mainly ensure the flexibility, reliability, and economy of the power system. When a line needs maintenance or malfunctions, power can be switched to other lines through the busbar. To ensure the normal use of busbars, tensile testing is usually required after the busbars are manufactured.

[0003] Publication No. CN115753385A discloses a tensile strength testing device for automotive electronic wiring harnesses, comprising a main frame, a movable plate, and a bottom locking mechanism. The bottom locking mechanism includes a pair of lower clamping arms hinged to a first bracket. The first clamping arm on the left is connected to a first pull wire, and the second clamping arm on the right is connected to a second pull wire. The first pull wire applies a rightward pulling force to the first clamping arm, and the second pull wire applies a leftward pulling force to the second clamping arm. The first and second pull wires are respectively connected to the movable plate. A first spring is connected in series on the first pull wire, and a second spring is connected in series on the second pull wire. This bottom locking mechanism allows the wiring harness to be placed between the lower clamping arms without requiring significant force from the operator. During wiring harness testing, the greater the pulling force exerted by the movable plate on the wiring harness, the greater the clamping force of the lower clamping arms on the wiring harness.

[0004] Although the aforementioned applications and prior art can effectively clamp the conductors and prevent them from loosening during the testing process, when the aforementioned applications and prior art are used to perform tensile testing on busbars, the busbars are bent, which leads to errors in the test results. Furthermore, when correcting the bent parts of the busbars, the correction force cannot be effectively controlled, resulting in sharp turns during the correction process. In addition, during the correction process, the correction rollers need to be in continuous contact with the busbars, which can lead to damage of the correction rollers after prolonged use, resulting in insufficient contact between the correction rollers and the busbars, thus affecting the correction of the busbars. Therefore, this invention proposes a busbar tensile testing device based on the production of busbar drain clamps. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a busbar tensile testing device based on busbar drain clamps. This device offers advantages such as preventing bending, avoiding over-correction, and preventing damage. It solves the problems of errors in test results due to busbar bending during tensile testing as described in the aforementioned applications and existing technologies. Furthermore, it addresses the difficulty in effectively controlling the correction force when correcting bent sections of the busbar, leading to sharp turns during correction. Additionally, the continuous contact between the correction roller and the busbar during correction can cause damage over time, resulting in insufficient contact and affecting busbar correction.

[0009] Furthermore, the damage prevention component includes a fixed plate fixedly connected to the surface of the U-shaped platform and an air supply cylinder fixedly connected to the inside of the test chamber. One end of the fixed plate is fixedly connected to a push rod, and one end of the push rod is fixedly connected to a push disk. A first one-way valve is provided on the surface of the push disk, and the push disk is slidably connected to the inside of the air supply cylinder.

[0010] Furthermore, the damage prevention component also includes a fixed cylinder fixedly connected to the top of the U-shaped platform. The fixed cylinder is connected to the air supply cylinder through an air supply pipe, and a second one-way valve is provided on the surface of the air supply pipe.

[0011] Furthermore, a push plate is slidably connected inside the fixed cylinder, a push rod is fixedly connected to the bottom of the push plate, a first spring is fixedly connected to the bottom of the push plate and the surface of the push rod, and the L-shaped plate is fixedly connected to the surface of the push rod.

[0012] Furthermore, the anti-wear component includes a push cylinder fixedly connected to the side of the fixed plate away from the push rod and an air inlet cylinder fixedly connected inside the test chamber. A second spring is fixedly connected inside the push cylinder, and a support plate is slidably connected inside the push cylinder. One side of the support plate is fixedly connected to one side of the second spring. A push rod is fixedly connected to the side of the support plate away from the second spring. A push disk is fixedly connected to one end of the push rod, and the push disk is slidably connected inside the air inlet cylinder.

[0013] Furthermore, the anti-wear component also includes an air storage cylinder fixedly connected to the top of the support plate and a drive disc fixedly connected to the top of the support plate. The air storage cylinder and the air inlet cylinder are connected through an air inlet pipe. A third one-way valve is provided on the surface of the air inlet pipe.

[0015] Furthermore, the wear-resistant component also includes a support frame fixedly connected to the top of the support plate, a frame toothed plate slidably connected to the surface of the support frame, the frame toothed plate meshing with an irregular gear, and switching strips fixedly connected to both sides of the frame toothed plate.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a busbar tensile testing device based on busbar drain clamp production, which has the following beneficial effects: 1. This busbar tensile testing device, based on busbar drain clamps, uses a straightening component to place both ends of the busbar inside the drain clamp platform. The busbar is straightened by a tensioning mechanism. Then, the drive cylinder is activated via the control panel. The drive cylinder moves the U-shaped platform on top of the moving platform via a telescopic rod. The U-shaped platform moves the support plate via an L-shaped plate, which in turn moves the rubber roller via a rotating rod. The movement of the rubber roller corrects the bent parts of the busbar, thus preventing the busbar from bending and achieving the effect of preventing bending.

[0017] 2. This busbar tensile testing device, based on busbar drain clamps, utilizes a combination of a straightening component and a damage prevention component. When the U-shaped platform moves, the platform moves a push rod via a fixed plate, causing the push rod to move a push plate inside the air delivery cylinder. This allows air from inside the air delivery cylinder to be delivered to the fixed cylinder via an air delivery pipe. As the gas level inside the fixed cylinder increases, the gas pushes a push rod down slowly via a push plate. The push rod then moves a support plate down gradually via an L-shaped plate. The support plate then moves a rubber roller down via a rotating rod. Therefore, when the rubber roller straightens the busbar, it does not excessively compress the busbar, thus preventing damage and achieving the effect of avoiding over-straightening.

[0018] 3. This busbar tensile testing device, based on the production of busbar drain clamps, utilizes the combined use of a straightening component and an anti-wear component. During the process of the U-shaped platform returning to its initial state, the fixed plate, driven by the push cylinder, gradually retracts the support plate and push rod into the push cylinder. Simultaneously, the push rod drives the push plate to move within the air inlet cylinder, allowing air from inside the air inlet cylinder to enter the air storage cylinder through the air inlet pipe. As the U-shaped platform continues to reciprocate, the gas level inside the air storage cylinder reaches the threshold of the pressure relief valve, allowing the gas to enter the drive plate through the connecting pipe. This causes the arc-shaped blades to drive the irregular gears to rotate via the fixed rod. When the irregular gears drive the meshing frame toothed plate to move, the frame toothed plate, through the switching strip, moves the rubber roller on the surface of the rotating rod. This prevents continuous contact between the rubber roller and the busbar, thus avoiding wear on the surface of the rubber roller and achieving the effect of preventing damage.

[0019] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0022] 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.

[0023] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 3 A busbar tensile testing device based on busbar drain clamps includes: a test chamber 1 and a tensile mechanism 13 disposed inside the test chamber 1. The movable stage 12 is fixedly connected inside the test chamber 1. The surface of the test chamber 1 is provided with a control panel 11. The inside of the test chamber 1 is provided with two flow-guiding clamps 131, one of which is provided on the surface of the tensioning mechanism 13. The correction component 2 is set inside the test box 1 and is used to correct the soft busbar to avoid errors in the test results due to bending of the busbar. The correction component 2 includes a U-shaped platform 22 that is slidably connected to the top of the moving platform 12. A support plate 23 is set inside the U-shaped platform 22. A rotating rod 231 is rotatably connected inside the support plate 23. A rubber roller 232 is slidably connected to the surface of the rotating rod 231. The damage prevention component 3 is installed on the surface of the correction component 2 to prevent the busbar from being over-corrected locally due to uneven force when the correction component 2 is correcting the busbar. The anti-wear component 4 is disposed on the surface of the straightening component 2 to prevent the rubber roller 232 from wearing out due to prolonged use, thus preventing insufficient contact between the rubber roller 232 and the busbar. It should be noted that the drainage clamp 131 is existing technology, so it will not be described in detail here. The tensioning mechanism 13 includes a telescopic cylinder fixedly connected to one side of the test chamber 1. The output end of the telescopic cylinder is differentially connected to a connecting rod. A connecting block is fixedly connected to the surface of the connecting rod. The top of the connecting block is fixedly connected to the bottom of one of the drainage clamps 131. The test chamber 1 is equipped with a camera component. The busbar is stretched by the tensioning mechanism 13. Then, the real-time status of the busbar is observed by the camera component, and the observation results are transmitted to the control panel 11. When a tensile test is required on the busbar, both ends of the busbar are placed inside the two drain clamps 131 respectively. The two ends of the busbar are fixed by using the drain clamps 131. Then, the tensioning mechanism 13 drives one of the drain clamps 131 to move, so that the drain clamp 131 performs a tensile test on the busbar. For a specific embodiment two, please refer to Figures 1 to 6 Based on the busbar tensile testing device based on busbar drain clamp production provided in Specific Embodiment 1, this embodiment provides a further technical solution: The correction assembly 2 also includes a drive cylinder 21 fixedly connected to one side of the test box 1. The output end of the drive cylinder 21 is differentially connected to a telescopic rod 211. One end of the telescopic rod 211 is fixedly connected to one side of the U-shaped platform 22. The U-shaped platform 22 has moving grooves 221 on opposite sides inside. An L-shaped plate 222 is slidably connected inside the moving groove 221. The bottom of the L-shaped plate 222 is fixedly connected to the top of the support plate 23. When it is necessary to correct the bent portion of the busbar so that the bent portion does not affect the test results, both ends of the busbar are placed inside the drain clamp 131. The busbar is straightened by the tensioning mechanism 13. Then, the drive cylinder 21 is started through the control panel 11. The drive cylinder 21 drives the U-shaped stage 22 to move back and forth on the top of the moving stage 12 through the telescopic rod 211. The U-shaped stage 22 drives the support plate 23 to move through the L-shaped plate 222. In turn, the support plate 23 drives the rubber roller 232 to move through the rotating rod 231. The reciprocating movement of the rubber roller 232 corrects the bent portion of the busbar, thereby preventing the surface of the busbar from bending. Therefore, when the busbar is subjected to tensile testing in the future, the surface of the busbar will not affect the accuracy of the test results due to the presence of the bent portion. For a specific embodiment three, please refer to Figures 1 to 10 Based on the busbar tensile testing device produced using busbar drain clamps provided in Specific Embodiment 2, this embodiment provides a further technical solution: The damage prevention component 3 includes a fixed plate 31 fixedly connected to the surface of the U-shaped platform 22 and an air supply cylinder 32 fixedly connected to the inside of the test chamber 1. A push rod 311 is fixedly connected to one end of the fixed plate 31, and a push disk 312 is fixedly connected to one end of the push rod 311. A first one-way valve 313 is provided on the surface of the push disk 312. The push disk 312 is slidably connected to the inside of the air supply cylinder 32. The damage prevention component 3 also includes a fixed cylinder 33 fixedly connected to the top of the U-shaped platform 22. The fixed cylinder 33 and the air supply cylinder 32 are connected through an air supply pipe 321. A second one-way valve 322 is provided on the surface of the air supply pipe 321. A push plate 331 is slidably connected inside the fixed cylinder 33. A push rod 332 is fixedly connected to the bottom of the push plate 331. A first spring 333 is fixedly connected to the bottom of the push plate 331 and located on the surface of the push rod 332. An L-shaped plate 222 is fixedly connected to the surface of the push rod 332. To prevent the rubber roller 232 from excessively squeezing the busbar, which could cause a "sharp turn" on the surface of the busbar, when the U-shaped platform 22 moves, the U-shaped platform 22 drives the push rod 311 to move through the fixed plate 31. The push rod 311 drives the push plate 312 to move inside the air supply cylinder 32, thereby transporting the air inside the air supply cylinder 32 to the inside of the fixed cylinder 33 through the air supply pipe 321. As the gas inside the fixed cylinder 33 continuously increases, the gas drives the push rod 332 to slowly descend through the push plate 331. The push rod 332 then drives the support plate 23 to gradually descend through the L-shaped plate 222. The support plate 23 then drives the rubber roller 232 to slowly descend through the rotating rod 231. Therefore, when the rubber roller 232 reciprocates at the top of the busbar, the pressure of the rubber roller 232 is within the range that the busbar can withstand. Therefore, when the rubber roller 232 corrects the busbar, it will not excessively squeeze the busbar, thus preventing a "sharp turn" from appearing on its surface. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the busbar tensile testing device produced using busbar drain clamps provided in Specific Embodiment 3, this embodiment provides a further technical solution: The anti-wear component 4 includes a push cylinder 41 fixedly connected to the side of the fixed plate 31 away from the push rod 311 and an air inlet cylinder 42 fixedly connected inside the test chamber 1. A second spring 411 is fixedly connected inside the push cylinder 41, and a support plate 412 is slidably connected inside the push cylinder 41. One side of the support plate 412 is fixedly connected to one side of the second spring 411. A push rod 413 is fixedly connected to the side of the support plate 412 away from the second spring 411. A push disk 414 is fixedly connected to one end of the push rod 413. The push disk 414 is slidably connected inside the air inlet cylinder 42. The anti-wear component 4 also includes an air storage cylinder 43 fixedly connected to the top of the support plate 23 and a drive disk 44 fixedly connected to the top of the support plate 23. The air storage cylinder 43 and the air inlet cylinder 42 are connected through an air inlet pipe 421. A third one-way valve 422 is provided on the surface of the air pipe 421. The air storage cylinder 43 and the drive disc 44 are connected by a connecting pipe 431. A pressure relief valve is provided on the surface of the connecting pipe 431. A fixed rod 441 is rotatably connected inside the drive disc 44. Several arc-shaped blades 442 are fixedly connected on the surface of the fixed rod 441 and inside the drive disc 44. An exhaust pipe 443 is fixedly connected to the surface of the drive disc 44. An irregular gear 444 is fixedly connected on the surface of the fixed rod 441 and outside the drive disc 44. The anti-wear component 4 also includes a support frame 45 fixedly connected to the top of the support plate 23. A frame toothed plate 451 is slidably connected to the surface of the support frame 45. The frame toothed plate 451 meshes with the irregular gear 444 for transmission. Switching bars 452 are fixedly connected to both sides of the frame toothed plate 451. To prevent excessive wear on the surface of the rubber roller 232 in contact with the busbar after continuous use, during the process of the U-shaped platform 22 returning to its initial state, the fixed plate 31, through the push cylinder 41, drives the support plate 412 and the push rod 413 to gradually retract into the push cylinder 41. During this process, as the push rod 413 drives the push plate 414 to move inside the air inlet cylinder 42, the air inside the air inlet cylinder 42 enters the air storage cylinder 43 through the air inlet pipe 421. When the U-shaped platform 22 continues to reciprocate, the gas inside the air storage cylinder 43 reaches the pressure relief valve. The threshold is reached, which allows the gas inside the gas storage cylinder 43 to enter the interior of the drive disk 44 through the connecting pipe 431. This causes the arc-shaped blades 442 inside the drive disk 44 to drive the irregular gear 444 to rotate through the fixed rod 441. When the irregular gear 444 drives the meshing frame tooth plate 451 to move, the frame tooth plate 451 drives the rubber roller 232 to move on the surface of the rotating rod 231 through the switching bar 452. This prevents the rubber roller 232 from continuously contacting the busbar at a certain point, thereby avoiding wear on the surface of the rubber roller 232 and preventing errors in the busbar during the correction process.

[0025] Working Principle: During use, both ends of the busbar are placed inside the guide clamp 131. The busbar is straightened by the tensioning mechanism 13. Then, the drive cylinder 21 is activated via the control panel 11. The drive cylinder 21 drives the U-shaped platform 22 to reciprocate on the top of the moving platform 12 via the telescopic rod 211. This causes the U-shaped platform 22 to move the support plate 23 via the L-shaped plate 222. The support plate 23 then moves the rubber roller 232 via the rotating rod 231. The reciprocating movement of the rubber roller 232 corrects any bending in the busbar, preventing surface bending. Therefore, when performing tensile testing on the busbar, the surface bending will not affect the accuracy of the test results. It is important to prevent the rubber roller 232 from excessively bending the busbar. When compression causes a sharp turn on the surface of the busbar, as the U-shaped platform 22 moves, it drives the push rod 311 via the fixed plate 31. The push rod 311 then drives the push plate 312 to move inside the air cylinder 32, thus transporting air from inside the air cylinder 32 to inside the fixed cylinder 33 via the air pipe 321. As the gas inside the fixed cylinder 33 increases, the gas drives the push rod 332 to slowly descend via the push plate 331. The push rod 332 then drives the support plate 23 to gradually descend via the L-shaped plate 222. The support plate 23 then drives the rubber roller 232 to slowly descend via the rotating rod 231. Therefore, when the rubber roller 232 reciprocates at the top of the busbar, the pressure of the rubber roller 232 is within the busbar's shape. Within the tolerance range, when the rubber roller 232 corrects the busbar, it will not excessively compress the busbar, causing a "sharp turn" on its surface. It is necessary to prevent excessive wear on the surface of the rubber roller 232 in contact with the busbar after continuous use. During the process of the U-shaped platform 22 returning to its initial state, the fixed plate 31, through the push cylinder 41, drives the support plate 412 and push rod 413 to gradually retract into the push cylinder 41. During this process, the push rod 413 drives the push plate 414 to move inside the air inlet cylinder 42, allowing air inside the air inlet cylinder 42 to enter the air storage cylinder 43 through the air inlet pipe 421. As the U-shaped platform 22 continues to reciprocate, the gas inside the air storage cylinder 43 reaches the pressure relief valve. The threshold is set so that the gas inside the gas storage tank 43 enters the drive disk 44 through the connecting pipe 431. This causes the arc-shaped blades 442 inside the drive disk 44 to drive the irregular gear 444 to rotate via the fixed rod 441. When the irregular gear 444 drives the meshing frame tooth plate 451 to move, the frame tooth plate 451 drives the rubber roller 232 to move on the surface of the rotating rod 231 via the switching bar 452. This prevents the rubber roller 232 from continuously contacting the busbar at a certain point, thus avoiding wear on the surface of the rubber roller 232 and preventing errors in the busbar during the correction process. When tensile testing of the busbar is required, both ends of the busbar are placed inside the two drain clamps 131 respectively. The drain clamps 131 are used to fix both ends of the busbar.Then, the tensioning mechanism 13 moves one of the drain clamps 131, causing the drain clamp 131 to perform a tensile test on the busbar.
