Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a marine transformer tester. Background Technology

[0002] With the massive consumption of fossil fuels and severe environmental pollution, renewable energy is receiving increasing attention from countries around the world. Wind energy has become one of the most competitive new energy sources. Compared to onshore wind power, offshore wind power not only does not occupy land resources, but also has abundant energy, stable output, and high utilization rate, making it a new direction for wind power development worldwide. The electrical equipment of offshore wind power substation platforms is an important component of offshore wind power. Among them, transformers are devices that use the principle of electromagnetic induction to change AC voltage. Their main components are primary coils, secondary coils, and iron cores. Their main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Therefore, transformers are one of the main pieces of equipment in the power system and an indispensable component. Their performance directly affects the safe operation of the power system, making transformer testing particularly important.

[0003] Currently, fully automatic transformer comprehensive testing equipment is used for factory testing and evaluation of the main electrical performance of power transformers, realizing real-time monitoring of the entire testing process. The current comprehensive testing equipment is equipped with rollers at the bottom to facilitate the movement of the entire testing equipment, and the testing equipment is moved by pulling a U-shaped handle on one side. However, the handles on the current testing equipment are all exposed and fixed designs, and the handles cannot be stored. During the use of the testing equipment, the staff are prone to accidentally bumping into the handles, which is inconvenient. Therefore, we propose a marine transformer testing instrument. Summary of the Invention

[0004] The purpose of this invention is to provide a marine transformer tester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a marine transformer tester, comprising a housing and a tester body disposed within the housing, and further comprising a movable support plate disposed on the housing;

[0006] A guide wheel assembly is mounted on the movable support plate and in contact with the ground, used to move the main body of the device;

[0007] An auxiliary component is disposed inside the housing, which drives the movable support plate to move so that the guide wheel assembly retracts into the housing.

[0008] A handle, which is disposed on the housing;

[0009] A linkage component, located within the housing, moves the movable support plate and uses this component to deflect and retract the handle into the housing. Unlike existing technologies, in actual use, the auxiliary component moves the movable support plate, thereby retracting the casters and friction wheels into the housing. This allows the casters and friction wheels to be retracted when the main body of the device is not moved, preventing them from bearing pressure for extended periods and thus extending the device's lifespan. Simultaneously, the linkage component deflects the handle into its placement slot, preventing accidental contact between the handle and the operator during use on the testing platform, thus improving the comfort of using the device.

[0010] Preferably, the guide wheel assembly includes two omnidirectional wheels symmetrically arranged at one end of the movable support plate;

[0011] Furthermore, two mounting brackets are symmetrically arranged at one end of the movable support plate, and each of the two mounting brackets is equipped with a shaft, and the shaft is equipped with a friction wheel that contacts the ground.

[0012] Preferably, the auxiliary component includes two shafts symmetrically arranged inside the housing, each shaft having a screw rod that passes through the movable support plate. Rotating the two shafts causes the movable support plate to move.

The movable support plate is provided with a one-way locking component, so that pushing the handle can make the main body of the device move forward, while the one-way locking component can be used to restrict the main body of the device from moving backward.

[0017] Preferably, the one-way locking assembly includes a gear disk 1 disposed on the shaft 1, a shaft 6 disposed on the movable support plate, a rotating disk disposed on the shaft 6, and a plurality of toothed grooves that mesh with the gear disk 1 are evenly spaced on the rotating disk, and the main body of the moving device drives the shaft 6 to rotate.

[0018] A disk is provided at one end of the shaft six. Multiple triangular grooves are evenly spaced on the disk. Two shafts seven are symmetrically arranged on one side of the disk. Each shaft seven is provided with a jack tooth. A limit block is provided between the two jack teeth. The limit block is used to keep the two jack teeth away from the triangular grooves so that the friction wheel can rotate freely.

[0019] A torsion spring is fitted on the shaft 7, and a limit plate is provided between the two shafts 7. One end of the torsion spring is connected to the limit plate and deflects the limit block so that one of the jack teeth is deflected into the triangular groove by the torsion spring to unidirectionally limit the rotation of the disk.

[0020] One end of the round rod is located inside the hollow rod and is provided with a limiting round plate. Both sides of the limiting round plate are provided with return springs. A synchronization component is provided inside the outer shell. In the initial state of the return spring, the synchronization component is used to make both of the jack teeth move away from the triangular groove, push the handle, and use the synchronization component to drive the limiting block to deflect.

[0021] Preferably, the synchronization component includes a shaft eight disposed on the limiting block, a gear disk two disposed at one end of the shaft eight, a guide rod disposed on the movable support plate, and a sliding plate disposed on the movable support plate, the guide rod passing through the sliding plate, and a rack one meshing with one of the gear disks two disposed at both ends of the sliding plate, and moving the sliding plate drives the shaft eight to rotate;

[0022] The outer casing is provided with a shaft nine, a gear disk three is provided on the shaft nine, and a rack two that meshes with the gear disk three is provided on one side of the sliding plate. Rotating the shaft nine causes the sliding plate to move.

[0027] Preferably, the housing is provided with a wire feeding groove.

[0028] This invention has at least the following beneficial effects:

[0029] Unlike existing technologies, in actual use, the auxiliary components drive the movable support plate to move, which in turn drives the casters and friction wheels to retract into the outer shell. This allows the casters and friction wheels to be retracted when the main body of the device does not need to be moved, thus avoiding them from bearing pressure for a long time and improving the life of the device. At the same time, the linkage components are used to deflect the handle into the placement slot, thereby preventing the staff from accidentally colliding with the handle during the use of the test bench, thus improving the comfort of using the main body of the device.

Detailed Implementation

[0037] 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.

[0038] Please see Figure 1-6 The present invention provides a technical solution: a marine transformer tester, including a housing 1 and a tester body 2 fixedly connected inside the housing 1, and also includes a movable support plate 3, which is set on the housing 1. A cover plate is rotatably connected to the housing 1 via a rotating shaft. The cover plate is opened and a wire is taken out from the wire feeding groove 113 to connect the tester body 2 and the transformer, thereby testing the transformer.

[0039] Guide wheel assembly 4 is mounted on movable support plate 3 and contacts the ground, used to move the main body of the device, thereby improving the flexibility of the main body of the device;

[0040] Auxiliary component 5 is installed inside the housing 1. The auxiliary component 5 drives the movable support plate 3 to move so that the guide wheel assembly 4 can be retracted into the housing 1. This allows the guide wheel assembly 4 to be retracted without moving the main body of the device, thereby avoiding it from being subjected to pressure for a long time and thus improving the life of the device.

[0041] Handle 6 is provided on the outer casing 1 to assist in moving the main body of the device;

[0042] Linkage component 7 is installed inside the outer casing 1. The movable support plate 3 is moved and the handle 6 is deflected and retracted into the outer casing 1 by the linkage component 7, thereby avoiding accidental contact between the staff and the handle during the use of the test bench, and thus improving the comfort of the main body of the device when using it.

[0043] The guide wheel assembly 4 includes two universal wheels 41 symmetrically arranged at one end of the movable support plate 3, and the universal wheels 41 are fixedly connected to the movable support plate 3;

[0044] Furthermore, two mounting brackets 42 are symmetrically fixedly connected to one end of the movable support plate 3. Each mounting bracket 42 is rotatably connected to a shaft 43 via bearings. A friction wheel 44 that contacts the ground is fixedly connected to the shaft 43, thereby assisting the movement of the main body of the device through the friction wheel 44.

[0045] The auxiliary component 5 includes two shafts 51 symmetrically arranged inside the outer casing 1. The shafts 51 are rotatably connected to the inner wall of the outer casing 1 via bearings. Each shaft 51 is fixedly connected to a screw 52. The screw 52 passes through the movable support plate 3 and is connected to it via threads. Rotating the two shafts 51 drives the two screws 52 to rotate, thereby driving the movable support plate 3 to move, which in turn drives the caster wheel 41 and the friction wheel 44 to retract into the outer casing 1.

[0046] Two shafts 51 are fixedly connected to one end of a timing pulley 53. The two timing pulleys 53 are connected by a timing belt. A dual-shaft motor 54 is fixedly connected inside the housing 1. One output shaft of the dual-shaft motor 54 is fixedly connected to one shaft 51. The dual-shaft motor 54 is started by program control to drive one shaft 51 to rotate. The timing pulleys 53 and the timing belt work together to drive the two shafts 51 to rotate.

[0047] The outer casing 1 has a placement slot 55;

[0048] The linkage component 7 includes two shafts 71 located at both ends of one side of the handle 6. Both shafts 71 are rotatably connected to the inner wall of the outer casing 1 via bearings. One end of one shaft 71 is fixedly connected to a worm gear 72. Inside the outer casing 1, a shaft 73 is rotatably connected via bearings. One end of the shaft 73 is fixedly connected to a worm gear 74 that meshes with the worm gear 72, and another end of the shaft 73 is fixedly connected to a synchronous pulley 75. A synchronous pulley 75 is also fixedly connected to one output shaft of the dual-axis motor 54. The two synchronous pulleys 75 are connected by a synchronous belt. The dual-axis motor 54 is started by program control, and the synchronous pulleys 75 and the synchronous belt work together to drive the shaft 73 to rotate, thereby driving the worm gear 74 to rotate, which in turn drives the worm gear 72 to rotate, which in turn drives the shaft 71 to rotate, thereby causing the handle 6 to deflect into the placement slot 55.

[0049] Both ends of one side of the handle 6 are fixedly connected to round rods 76. One end of the round rod 76 is provided with a hollow rod 77, and one end of the hollow rod 77 is fixedly connected to a shaft 71. The movable support plate 3 is provided with a one-way locking component 78. Pushing the handle 6 makes the main body of the device move forward, while the one-way locking component 78 only restricts the main body of the device from moving backward. Thus, when the staff pushes the main body of the device to move uphill, such as when maintenance personnel need to perform maintenance and inspection on the offshore transformer, they may need to get on the plate from the ship at sea to the offshore wind power booster station. When pushing the main body of the device on the plate, the one-way locking component 78 can be used to prevent the main body of the device from sliding downhill, thus ensuring the safety of the maintenance personnel. Conversely, pulling the handle 6 moves the main body of the device backward, while the one-way locking component 78 only restricts the main body of the device from moving forward.

[0050] The one-way locking assembly 78 includes a gear disk 79 fixedly connected to shaft 43. A shaft 81 is rotatably connected to the movable support plate 3 via a bearing. A rotating disk 82 is fixedly connected to one end of shaft 81. Multiple tooth grooves 83 that mesh with gear disk 79 are evenly spaced on the rotating disk 82. The main body of the moving device drives the friction wheel 44 to roll, thereby driving shaft 43 to rotate, which in turn drives gear disk 79 to rotate, which in turn drives rotating disk 82 to rotate, which in turn drives shaft 81 to rotate. Conversely, it restricts the rotation of shaft 81, thereby restricting the rotation of friction wheel 44, which in turn can prevent the movement of the main body of the device.

[0051] One end of shaft 81 passes through the movable support plate 3 and is fixedly connected to a disc 84. Multiple triangular grooves 85 are evenly spaced on the disc 84, and two shafts 86 are symmetrically arranged on one side of the disc 84. Both shafts 86 are rotatably connected to the movable support plate 3 through bearings. Both shafts 86 are fixedly connected to jack teeth 87. A limit block 88 is provided between the two jack teeth 87. The limit block 88 is used to keep the two jack teeth 87 away from the triangular grooves 85, so that the friction wheel 44 can rotate freely, thereby satisfying the operation of the main body of the device to turn at will.

[0052] A torsion spring 89 is fitted on the shaft 7 86, and a limit plate 91 is provided between the two shafts 7 86. The limit plate 91 is rotatably connected to the shaft 7 86 through a bearing. One end of the torsion spring 89 is fixedly connected to the limit plate 91, and the other end is fixedly connected to the shaft 7 86. The limit block 88 is deflected to release one jack tooth 87. At the same time, it is reset by the torsion spring 89 and deflected into the triangular groove 85 to limit the rotation of the disc 84 in one direction. Meanwhile, the other jack tooth 87 is always away from the triangular groove 85.

[0053] One end of the round rod 76 is located inside the hollow rod 77 and is fixedly connected to the limiting round plate 92. The limiting round plate 92 is slidably connected to the inner wall of the hollow rod 77, and a return spring 93 is provided on both sides of the limiting round plate 92. One end of the return spring 93 contacts the inner wall of the hollow rod 77, and a synchronization component 94 is provided inside the outer casing 1. In the initial state of the return spring 93, the synchronization component 94 is used to make the two jack teeth 87 move away from the triangular groove 85, push the handle 6, and use the synchronization component 94 to drive the limiting block 88 to deflect. At the same time, the return spring 93 is compressed to provide the handle 6 with self-recovery capability.

[0054] The synchronization component 94 includes a shaft 95 fixedly connected to the limiting block 88. One end of the shaft 95 is rotatably connected to the movable support plate 3 via a bearing. A gear 96 is fixedly connected to one end of the shaft 95. A guide rod 97 is fixedly connected to the movable support plate 3, and a sliding plate 98 is provided on the movable support plate 3. The guide rod 97 slides through the sliding plate 98, and both ends of the sliding plate 98 are fixedly connected to a rack 99 that meshes with a gear 96. Moving the sliding plate 98 causes the rack 99 to move, thereby causing the gear 96 to rotate, which in turn causes the shaft 95 to rotate.

[0055] Inside the outer casing 1, a shaft 9 101 is rotatably connected via a bearing. A gear disk 3 102 is slidably connected to the shaft 9 101, and a rack 2 103 that meshes with the gear disk 3 102 is fixedly connected to one side of the sliding plate 98. Rotating the shaft 9 101 causes the gear disk 3 102 to rotate, thereby causing the rack 2 103 to move, which in turn causes the sliding plate 98 to move.

[0056] A sliding groove 104 is provided on the shaft nine 101, and a sliding protrusion 105 is fixedly connected inside the gear disk three 102, with one end located in the sliding groove 104. The sliding protrusion 105 is slidably connected to the inner wall of the sliding groove 104. At the same time, rotating the shaft nine 101 drives the gear disk to rotate. Limiting rods 106 are slidably connected to both sides of the gear disk three 102. Both limiting rods 106 are fixedly connected to the rack two 103. Then, moving the movable support plate 3 drives the rack two 103 to move, thereby driving the limiting rods 106 to move, thereby driving the gear disk three 102 to move, so that the gear disk three 102 and the rack two 103 are always meshed.

[0057] A hollow shaft 107 is fixedly connected to one end of shaft nine 101. Shaft ten 108 is rotatably connected to the hollow shaft 107 via a bearing. Shaft ten 108 and shaft three 71 are designed to be coaxial. One end of shaft ten 108 is located inside the hollow shaft 107. A connecting rod 109 is provided between one end of shaft ten 108 and handle 6. Both ends of the connecting rod 109 are rotatably connected to shaft ten 108 and handle 6 via rotating shafts. The two ends of the connecting rod 109 rotate relative to shaft ten 108 and handle 6, respectively. Pushing handle 6 drives the connecting rod 109 to move, thereby causing shaft ten 108 to deflect, and then causing shaft nine 101 to rotate.

[0058] A connecting plate 111 is provided between the two shafts 95, and the shafts 95 and the connecting plate 111 are rotatably connected by bearings.

[0059] A U-shaped connecting rod 112 is fixedly connected between the two shafts 71 to improve the stability of the handle 6.

[0060] The outer casing 1 is provided with a cable tray 113 for storing connecting cables.

[0061] During normal operation of the offshore transformer tester, pushing handle 6 moves connecting rod 109, which in turn causes shaft 10 108 to deflect, which in turn causes shaft 9 101 to rotate, which in turn causes gear disc 3 102 to rotate, which in turn causes rack 2 103 to move, which in turn causes sliding plate 98 to move, which in turn causes rack 1 99 to move, which in turn causes gear disc 2 96 to rotate, which in turn causes shaft plate to rotate, which in turn causes limit block 88 to deflect, releasing one jack tooth 87. At the same time, it uses torsion spring 89 to reset and deflect into triangular groove 85 to unidirectionally limit the rotation of disc 84. Meanwhile, the other jack tooth 87 is always away from triangular groove 85, so that the device can only move in the direction of movement of handle 6, thus preventing accidents when the test platform is going uphill or downhill. After the device moves to the designated position, it is started by program control. A dual-axis motor 54 drives a second shaft 51 to rotate, which in turn drives two second shafts 51 to rotate via a timing pulley 53 and a timing belt. This, in turn, drives two screws 52 to rotate, thereby moving the movable support plate 3. This, in turn, causes the casters 41 and friction wheels 44 to retract into the outer casing 1. This allows the casters 41 and friction wheels 44 to be retracted when the main body of the device does not need to be moved, thus avoiding prolonged pressure on them and improving the device's lifespan. At the same time, a timing pulley 75, in conjunction with a timing belt, drives a fourth shaft 73 to rotate, which in turn drives a worm gear 74 to rotate, which in turn drives a worm wheel 72 to rotate, thereby driving a third shaft 71 to rotate. This causes the handle 6 to deflect into the placement slot 55, thus preventing accidental contact between the handle and the user during use of the test bench and improving the comfort of using the main body of the device.
