Description

Technical Field

[0001] This utility model relates to the technical field of water turbine testing, and in particular to an integrated dual-function testing device for impulse turbine units. Background Technology

[0002] Impulse turbines, as an important type of power equipment, are widely used in high-drop hydroelectric power plants. Inspecting the nozzle and water bucket profiles of impulse turbines in high-drop hydroelectric power plants is a crucial step in ensuring efficient operation, extending equipment life, and preventing malfunctions. By inspecting the water bucket and nozzle profiles, potential faults can be detected promptly, allowing for proactive maintenance and preventing escalation of problems that could lead to equipment damage or even production accidents.

[0003] However, current testing devices for impact turbine units have several limitations. Firstly, traditional testing devices are relatively simple in function, often only capable of detecting a single water tank or nozzle profile. In practical applications, to comprehensively understand the unit's operating status, multiple different types of testing equipment need to be used simultaneously, occupying significant installation space, resulting in a complex and chaotic site layout. Furthermore, frequent equipment changes can impact testing efficiency. Secondly, the installation of these testing devices is typically cumbersome, often relying on bolted connections. The installation, commissioning, and replacement of these devices require considerable time and manpower, and frequent disassembly and reassembly can easily damage the equipment, affecting testing accuracy and extending its lifespan.

[0039] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0040] See Figure 1-4 As shown;

[0041] An integrated dual-function testing device for an impact turbine generator set according to an embodiment of this utility model includes:

[0042] Base 1 is supported on the ground, and a lifting component is installed on base 1;

[0043] Telescopic cylinder 2 is mounted on the lifting assembly, and a mounting plate is provided at the output end of telescopic cylinder 2.

[0044] Two clamping components 3 are symmetrically arranged on the mounting base plate.

[0045] The clamping component 3 includes:

[0046] The clamping base 31 is fixedly connected to the mounting base plate, and the clamping base 31 has a transmission cavity inside.

[0047] The cover plate 32 is fixedly installed on the clamping base 31;

[0048] Two magnet blocks 33 are symmetrically embedded in the cover plate 32;

[0049] The detection base 34 is magnetically attached to the two magnetic blocks 33;

[0050] The testing device 35 is fixedly connected to the testing base 34 and is integrated with the testing base 34 as a whole;

[0051] By adopting the above technical solution, the testing device 35, which is fixed as a whole with the testing base 34, is moved to the clamping assembly 3, so that the testing base 34 moves closer to the two magnetic blocks 33 in the cover plate 32. Since the testing base 34 and the magnetic blocks 33 can be magnetically attached, the testing base 34 will quickly adhere to the surface of the cover plate 32 under the action of magnetic force, thus initially achieving the positioning and fixing of the testing device 35. In this process, there is no need to use bolts or other tools for cumbersome connections. The initial installation can be completed by magnetic attraction alone, which greatly simplifies the installation operation process. By fixing the testing device 35 to the testing base 34, multiple testing functions can be integrated, and multiple parameters of the impact unit can be monitored in real time at the same time. This avoids the situation where traditional testing devices have a single function and require the use of multiple different types of testing devices at the same time, which simplifies the on-site layout and makes the testing work more efficient and convenient. The magnetic attraction of the magnetic blocks 33 allows the testing base 34 to be quickly attached to the cover plate 32 without the need for traditional connection methods such as bolts. This greatly simplifies the installation, debugging and replacement process of the testing device, saves a lot of time and manpower, and improves work efficiency.

[0052] As a preferred embodiment of the above technical solution, such as Figures 2 to 3 As shown, the clamping assembly 3 also includes:

[0053] The pressure rod 36 is slidably inserted into the cover plate 32;

[0054] The slide plate 37 is slidably disposed inside the clamping base 31 and is driven to slide by the pressure rod 36;

[0055] Two hinge rods 38 are symmetrically mounted on both sides of the slide plate 37.

[0056] Two grippers 39 are symmetrically oscillating inside the clamping base 31, and the bottom of the grippers 39 is hinged to the hinge rod 38.

[0057] During the process of adsorbing the detection base 34 onto the magnet block 33, the detection base 34 will press the pressure rod 36 to slide inward. Then, the pressure rod 36 will drive the sliding plate 37 to slide. Then, the sliding plate 37 will be hinged with the hinge rod 38, which will cause the hinge rod 38 to swing. Then, the swinging hinge rod 38 will push the bottom of the gripper 39 to swing outward, which will cause the gripper end of the gripper 39 to swing inward, so that the gripper end of the gripper 39 is clamped on the detection base 34, which, together with the magnet block 33, forms a double fixation. This eliminates the need for bolts or other connection methods, ensuring stable installation of the detection equipment and allowing for quick assembly and disassembly of the detection equipment.

[0058] In this embodiment, a dual fixing method is formed by the magnetic attraction of the magnet 33 and the mechanical clamping of the gripper 39. The magnetic attraction provides initial adsorption and fixation, enabling the detection base 34 to be quickly positioned and initially fixed on the cover plate 32. The mechanical clamping further enhances the stability of the fixation, ensuring that the detection base 34 will not easily loosen or fall off during the operation of the impact unit, even if affected by external factors such as vibration. This ensures the stable installation of the detection equipment 35 and improves the accuracy and reliability of the detection data. Traditional connection methods such as bolts are not required, avoiding cumbersome bolt tightening and loosening operations. When installing the detection base 34, it is only necessary to bring it close to the magnet 33 for adsorption, which will automatically trigger the clamping action to complete the installation. When disassembling, only external force needs to be applied to overcome the magnetic attraction to quickly remove the detection base 34. This greatly saves time and manpower for installing, debugging, and replacing the detection equipment, and improves work efficiency.

[0059] As a preferred embodiment of the above technical solution, a rubber sleeve is fitted onto the outer end of the pressure rod 36;

[0060] In this embodiment, during the adsorption and separation process of the detection base 34, a certain impact force will be generated on the pressure rod 36; the rubber sleeve has good elasticity and can absorb and disperse this impact force, preventing the pressure rod 36 from being damaged due to direct large impact, thus extending the service life of the pressure rod 36.

[0061] As a preferred embodiment of the above technical solution, such as Figure 3 As shown, the clamping base 31 has two guide posts 3a inside, the guide posts 3a are parallel to the sliding direction of the pressure rod 36, and the slide plate 37 has two guide sleeves 3b symmetrically arranged on it, the two guide sleeves 3b are slidably sleeved on the two guide posts 3a.

[0062] In this embodiment, the cooperation between the guide post 3a and the guide sleeve 3b provides precise guidance for the movement of the slide plate 37. When the pressure rod 36 drives the slide plate 37 to slide, the slide plate 37 can only move along the straight line direction set by the guide post 3a, avoiding deviation, swaying or tilting of the slide plate 37 during the movement, and ensuring the straightness and accuracy of the movement of the slide plate 37. It enables the hinge rod 38 and the gripper 39 to swing according to the predetermined trajectory and angle, thereby realizing stable clamping and releasing of the detection base 34 and improving the working accuracy of the entire clamping assembly 3.

[0063] As a preferred embodiment of the above technical solution, such as Figure 1 and Figure 4 As shown, the lifting assembly includes:

[0064] The lifting bracket 11 is fixedly installed on the base 1;

[0065] Screw 12 is vertically rotatably installed inside lifting bracket 11, and screw 12 is driven to rotate by a motor;

[0066] The lifting sleeve 13 is slidably mounted on the lifting bracket 11.

[0067] The threaded slider 14 is threadedly sleeved on the screw 12 and is fixedly connected to the lifting sleeve 13.

[0068] In this embodiment, when the height of the detection device needs to be adjusted to meet the detection requirements of different positions or working states of the impact unit, the motor is started; the motor starts running and outputs power, driving the screw 12 to rotate inside the lifting bracket 11; when the screw 12 rotates, since the threaded slider 14 is threaded on the screw 12, the threaded slider 14 will move linearly along the axis of the screw 12, thereby driving the lifting sleeve 13 to slide up and down on the lifting bracket 11; so that the detection device can be accurately adjusted to the required height position, reducing the limitations of use.

[0069] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, four guide rails 15 are arranged in a quadrangular pattern on the outer wall of the lifting bracket 11. Two guide wheels 16 are rolled on each guide rail 15. Each guide wheel 16 is rotatably mounted on the inner wall of the lifting sleeve 13.

[0070] In this embodiment, the four guide rails 15 are arranged in a quadrangular pattern, providing all-round guidance for the lifting sleeve 13. The guide wheel 16 rolls on the guide rails 15, so that the lifting sleeve 13 can only move in a straight line along the vertical direction defined by the guide rails 15. This effectively avoids horizontal deviation, tilting or shaking of the lifting sleeve 13 during the sliding process, ensuring the stability and accuracy of the detection device during the lifting process. The guide wheel 16 moves by rolling on the guide rails 15. Compared with sliding friction, this reduces the friction force experienced by the lifting sleeve 13 during the up and down sliding process, which reduces the power required for the motor to drive the screw 12 to rotate, thereby reducing energy consumption and improving the motion efficiency of the entire lifting assembly.

[0071] As a preferred embodiment of the above technical solution, a counterweight is installed inside the base 1;

[0072] In this embodiment, the counterweight can reduce the swaying amplitude of the device caused by the vibration of the unit, making the detection device more stable during operation, ensuring that the detection equipment 35 can accurately collect various parameters of the impact unit, and improving the reliability of the detection data; the counterweight can maintain the center of gravity of the device, ensuring that the device remains stable under various motion states, and avoiding the impact of tilting or swaying on the detection accuracy.

[0073] As a preferred embodiment of the above technical solution, the base 1 is provided with four omnidirectional wheels at its bottom;

[0074] In this embodiment, the four casters at the bottom of the base 1 enable the detection device to move easily between various workstations without the need for tedious disassembly and reinstallation, thereby improving work efficiency, reducing production downtime caused by equipment handling, reducing the labor intensity of workers, and improving the safety of handling.

[0075] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
