Description

Technical Field

[0001] This utility model relates to the field of hydro-generator processing technology, specifically a fixing device for hydro-generators. Background Technology

[0002] A hydroelectric generator is a generator that uses a hydroelectric turbine as its prime mover to convert water energy into electrical energy. When water flows through the turbine, it converts water energy into mechanical energy. The turbine's shaft then drives the generator's rotor, converting the mechanical energy into electrical energy for output. It is the main power equipment for hydroelectric power stations to produce electricity. The production process of a hydroelectric generator involves many steps and processes, and many of these processing steps require fixing devices to clamp and secure the generator.

[0003] However, existing technologies have some problems:

[0004] During use, unstable clamping can cause slight displacement or shaking of the generator during processing, resulting in the dimensions of the processed parts not meeting the design requirements. It is impossible to accurately maintain the shape of the generator parts, which may lead to problems in the fit between the parts. Furthermore, uneven clamping force or unstable clamping points can cause relative sliding between the generator surface and the clamp, leaving scratches and abrasions on the surface. This not only affects the appearance of the generator but may also reduce its corrosion resistance and sealing performance. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a fixing device for a hydro-generator, which has the advantage of effectively pressing the outside and top of the hydro-generator. It solves the problems caused by unstable clamping, which can lead to slight displacement or shaking of the generator during processing, resulting in the dimensions of the processed parts not meeting the design requirements, failing to accurately maintain the shape of the generator parts, and potentially causing problems with the fit between the parts. Furthermore, uneven clamping force or unstable clamping points can cause relative sliding between the generator surface and the clamp, leaving scratches and abrasions on the surface. This not only affects the appearance of the generator but may also reduce its corrosion resistance and sealing performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for a hydro generator, comprising a workbench, a support frame, and a placement plate. The support frame is fixedly installed on the top of the workbench, and the placement plate is movably installed on the left and right sides of the top of the workbench. A fixing sleeve is fixedly installed inside the support frame, and a cylinder is movably installed inside the fixing sleeve. A clamping assembly is provided at the bottom of the workbench, and a control plate is fixedly installed on the right side of the support frame.

[0007] In a preferred embodiment of this utility model, the clamping assembly includes a motor, a transmission rod, an adjustment groove, and a clamping rod. The motor is fixedly installed at the bottom of the workbench, the transmission rod is connected to the output end of the motor, and the other end of the transmission rod passes through the workbench from bottom to top and is fixedly connected to the bottom of the placement plate. The adjustment groove is opened at the top of the placement plate, and three sets of the adjustment groove are arranged in a ring and are equally spaced. The clamping rod is movably installed inside the adjustment groove and is arranged in three sets.

[0008] As a preferred embodiment of this utility model, a connecting rod is fixedly installed on the top of the workbench, an adjusting plate is movably inserted into the top of the connecting rod, a reinforcing plate is fixedly installed at the bottom of the placement plate, and three sets of reinforcing plates are arranged in a ring and evenly distributed. The lower end of the clamping rod passes through the reinforcing plate from top to bottom and is fixedly connected to the top of the adjusting plate.

[0009] In a preferred embodiment of this utility model, the cylinder output end passes through the fixed sleeve from top to bottom and extends to the bottom of the fixed sleeve. A connecting plate is movably installed at the bottom of the fixed sleeve and is fixedly connected to the cylinder output end. A limit rod is fixedly installed inside the fixed sleeve, and the other end of the limit rod passes through the fixed sleeve from top to bottom and is fixedly connected to the top of the connecting plate.

[0010] As a preferred embodiment of this utility model, a telescopic rod is fixedly installed at the bottom of the connecting plate. Several sets of telescopic rods are arranged and distributed at equal intervals. A pressing plate is fixedly connected to the other end of the telescopic rod. A return spring is movably sleeved on the surface of the telescopic rod. The top end of the return spring is in contact with the bottom of the connecting plate, and the lower end of the return spring is in contact with the top of the pressing plate.

[0011] As a preferred embodiment of this utility model, the top of the placement plate is provided with a movable groove, a movable shaft is movably installed inside the movable groove, an auxiliary disk is fixedly installed at the top of the movable shaft, and the bottom of the auxiliary disk is movably fitted with the top of the placement plate.

[0012] As a preferred embodiment of this invention, a control button is fixedly installed on the right side of the control panel, and the control button is electrically connected to the cylinder and the motor via wires.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model incorporates a motor, a connecting rod, and a connecting plate. The motor output drives a transmission rod to rotate, which in turn rotates a placement plate. The rotation of the placement plate then synchronously rotates an adjusting sleeve. As the adjusting groove moves, the clamping rod moves inwards according to the groove's opening, thus clamping the hydro-generator. The connecting rod movably connects the adjusting plate and the clamping rod, allowing the clamping rod to move along the adjusting groove as the placement plate rotates. A reinforcing plate provides auxiliary protection for the clamping rod, preventing it from shifting during prolonged clamping. A cylinder output pushes the connecting plate downwards, adjusting the movement of the pressing plate. During movement, multiple sets of limit rods are moved, and the limit rods cooperate with the fixed sleeve to limit the movement of the connecting plate, thereby preventing the connecting plate from shifting during movement. This solves the problem that unstable clamping can cause slight displacement or shaking of the generator during processing, resulting in the dimensions of the processed parts not meeting the design requirements, failing to accurately maintain the shape of the generator parts, and potentially causing problems with the fit between parts. Furthermore, uneven clamping force or unstable clamping points can cause relative sliding between the generator surface and the clamp, leaving scratches and abrasions on the surface. This not only affects the appearance of the generator but may also reduce its corrosion resistance and sealing performance. It has the advantage of effectively pressing the outside and top of the hydro-generator.

[0015] 2. This utility model uses a clamping assembly set at the bottom of the workbench. The motor output drives the transmission rod to rotate, which in turn drives the placement plate to rotate. The rotation of the placement plate drives the adjusting sleeve to rotate synchronously. When the adjusting groove moves, the clamping rod moves inward according to the direction of the adjusting groove opening, thereby clamping the hydro-generator.

[0016] 3. This utility model uses a connecting rod set on the top of the workbench to movably connect the adjusting plate and the clamping rod, so that when the placement plate rotates, the clamping rod moves according to the adjusting groove. The clamping rod is further protected by a reinforcing plate, thus preventing the clamping rod from shifting due to prolonged clamping work. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides a fixing device for a hydro generator, including a workbench 1, a support frame 2 and a placement plate 3. The support frame 2 is fixedly installed on the top of the workbench 1, and the placement plate 3 is movably installed on the left and right sides of the top of the workbench 1. A fixing sleeve 4 is fixedly installed inside the support frame 2, and a cylinder 5 is movably installed inside the fixing sleeve 4. A clamping assembly 6 is provided at the bottom of the workbench 1, and a control plate 7 is fixedly installed on the right side of the right support frame 2.

[0023] refer to Figure 2 The clamping assembly 6 includes a motor 61, a transmission rod 62, an adjustment groove 63, and a clamping rod 64. The motor 61 is fixedly installed at the bottom of the workbench 1. The transmission rod 62 is connected to the output end of the motor 61. The other end of the transmission rod 62 passes through the workbench 1 from bottom to top and is fixedly connected to the bottom of the placement plate 3. The adjustment groove 63 is opened at the top of the placement plate 3. There are three sets of adjustment grooves 63, which are distributed in a ring at equal intervals. The clamping rod 64 is movably installed inside the adjustment groove 63 and is provided in three sets.

[0024] As a technical optimization of this utility model, the clamping assembly 6 set at the bottom of the workbench 1 drives the transmission rod 62 to rotate through the output end of the motor 61. The rotation of the transmission rod 62 drives the placement plate 3 to rotate. The rotation of the placement plate 3 drives the adjusting sleeve to rotate synchronously. When the adjusting groove 63 moves, the clamping rod 64 moves inward according to the groove opening direction of the adjusting groove 63, thereby enabling the clamping rod 64 to clamp the hydro-generator.

[0025] refer to Figure 2A connecting rod 8 is fixedly installed on the top of the workbench 1. An adjusting plate 9 is movably inserted into the top of the connecting rod 8. A reinforcing plate 10 is fixedly installed at the bottom of the placement plate 3. The reinforcing plate 10 is arranged in three sets and is distributed in a ring at equal intervals. The lower end of the clamping rod 64 passes through the reinforcing plate 10 from top to bottom and is fixedly connected to the top of the adjusting plate 9.

[0026] As a technical optimization of this utility model, the connecting rod 8 set on the top of the workbench 1 is used to movably connect the adjusting plate 9 and the clamping rod 64, so that when the placement plate 3 rotates, the clamping rod 64 moves according to the adjusting groove 63, and the reinforcing plate 10 provides auxiliary protection for the clamping rod 64, thereby preventing the clamping rod 64 from shifting due to prolonged clamping work.

[0027] refer to Figure 2 A connecting plate 11 is movably installed at the bottom of the fixed sleeve 4 and is fixedly connected to the output end of the cylinder 5. A limit rod 12 is fixedly installed inside the fixed sleeve 4. The other end of the limit rod 12 passes through the fixed sleeve 4 from top to bottom and is fixedly connected to the top of the connecting plate 11.

[0028] As a technical optimization of this utility model, the connecting plate 11 is set at the output end of the cylinder 5. The cylinder 5 pushes the connecting plate 11 downward to move the pressing plate 14. When the connecting plate 11 moves, it drives multiple sets of limiting rods 12 to move. The limiting rods 12 cooperate with the fixing sleeve 4 to limit the movement of the connecting plate 11, thereby preventing the connecting plate 11 from deviating during movement.

[0029] refer to Figure 3 A telescopic rod 13 is fixedly installed at the bottom of the connecting plate 11. Several sets of telescopic rods 13 are arranged at equal distances. A pressing plate 14 is fixedly connected to the other end of the telescopic rod 13. A return spring 15 is movably sleeved on the surface of the telescopic rod 13. The top end of the return spring 15 is in contact with the bottom of the connecting plate 11, and the lower end of the return spring 15 is in contact with the top of the pressing plate 14.

[0030] As a technical optimization of this utility model, a telescopic rod 13 is set at the bottom of the connecting plate 11 to connect the pressing plate 14. The telescopic rod 13 connects the pressing plate 14 to the connecting plate 11. The telescopic rod 13 and the pressing plate 14 move downward to press and fix the water turbine generator. The return spring 15 generates a thrust to apply pressure to the pressing plate 14 to press the water turbine generator. When the connecting plate 11 moves to its original position, the thrust generated by the return spring 15 pushes the pressing plate 14 to move to its original position.

[0031] refer to Figure 2The top of the placement plate 3 has a movable groove 16, and a movable shaft 17 is movably installed inside the movable groove 16. An auxiliary plate 18 is fixedly installed at the top of the movable shaft 17, and the bottom of the auxiliary plate 18 is movably fitted with the top of the placement plate 3.

[0032] As a technical optimization of this utility model, the movable groove 16 set on the top of the placement plate 3 is used to movably install the movable shaft 17 and the auxiliary disk 18, and then the auxiliary disk 18 is used to place and support the water turbine generator, thereby preventing the placement plate 3 from rotating and causing the water turbine generator to rotate synchronously, thus preventing the water turbine generator from deviating and increasing the processing difficulty.

[0033] refer to Figure 2 and Figure 3 A control button 19 is fixedly installed on the right side of the control panel 7. The control button 19 is electrically connected to the cylinder 5 and the motor 61 through wires.

[0034] As a technical optimization of this utility model, the cylinder 5 and the motor 61 are started and stopped by the control button 19 located on the right side of the control panel 7, which facilitates the clamping and processing of the water turbine generator.

[0035] The working principle and usage process of this utility model are as follows: During use, the auxiliary plate 18 supports the hydro-generator, preventing the placement plate 3 from rotating synchronously with the hydro-generator and thus avoiding displacement of the hydro-generator, which would increase processing difficulty. The output end of the motor 61 drives the transmission rod 62 to rotate, which in turn drives the placement plate 3 to rotate. The rotation of the placement plate 3 synchronously drives the adjusting sleeve. The connecting rod 8 connects the adjusting plate 9 and the clamping rod 64, allowing the clamping rod 64 to move according to the adjusting groove 63 when the placement plate 3 rotates. The reinforcing plate 10 provides auxiliary protection for the clamping rod 64, preventing displacement due to prolonged clamping. The cylinder 5 pushes the connecting plate 11 downward to move the pressing plate 14. When the connecting plate 11 moves, it drives multiple sets of limit rods 12 to move. The limit rods 12 cooperate with the fixing sleeve 4 to limit the movement of the connecting plate 11, thereby preventing the connecting plate 11 from shifting during movement. The telescopic rod 13 connects the pressing plate 14. When the connecting plate 11 moves downward, the telescopic rod 13 and the pressing plate 14 move downward to press and fix the hydro-generator. The return spring 15 generates a thrust to apply pressure to the pressing plate 14, thereby pressing the hydro-generator. When the connecting plate 11 moves to its original position, the thrust generated by the return spring 15 pushes the pressing plate 14 to move to its original position.

[0036] In summary, this fixing device for a hydro-generator, by setting up a motor 61, a connecting rod 8, and a connecting plate 11, drives the transmission rod 62 to rotate via the output end of the motor 61. The rotation of the transmission rod 62 drives the placement plate 3 to rotate, and the rotation of the placement plate 3 drives the adjusting sleeve to rotate synchronously. When the adjusting groove 63 moves, the clamping rod 64 moves inward according to the groove opening direction, thereby clamping the hydro-generator. The connecting rod 8 movably connects the adjusting plate 9 and the clamping rod 64, allowing the clamping rod 64 to move according to the adjusting groove 63 when the placement plate 3 rotates. The reinforcing plate 10 provides auxiliary protection for the clamping rod 64, preventing it from shifting due to prolonged clamping. The output end of cylinder 5 pushes the connecting plate 11 downward, thereby adjusting the movement of the pressing plate 14. When the connecting plate 11 moves, it drives multiple sets of limit rods 12 to move. The limit rods 12 cooperate with the fixed sleeve 4 to limit the movement of the connecting plate 11, thus preventing the connecting plate 11 from shifting during movement. This solves the problem that unstable clamping can cause slight displacement or shaking of the generator during processing, resulting in the dimensions of the processed parts not meeting the design requirements, failing to accurately maintain the shape of the generator parts, and potentially causing problems with the fit between parts. Furthermore, uneven clamping force or unstable clamping points can cause relative sliding between the generator surface and the clamp, leaving scratches and abrasions on the surface. This not only affects the appearance of the generator but may also reduce its corrosion resistance and sealing performance.
