Technical Field
[0001] This utility model relates to the field of hydropower unit testing technology, and more specifically, to a device for assessing the health status of hydropower equipment. Background Technology
[0002] Hydropower equipment refers to electromechanical equipment used in hydropower generation and related projects. Monitoring the health status of this equipment is therefore crucial. Hydropower equipment, especially key components such as turbines and pipelines, bears significant pressure and vibration loads. Internal welds, connections, and other structures are prone to cracks, corrosion, wear, and other faults. If these faults are not detected in time, they can lead to decreased equipment performance or even major malfunctions. However, existing hydropower equipment health status assessment devices still have the following shortcomings:
[0003] (1) Traditional methods for inspecting water turbine pipelines of hydropower equipment often rely on manual inspection, which is inefficient and prone to missed inspections. It is also susceptible to human factors and cannot achieve real-time monitoring.
[0004] (2) The current method of manually inspecting each weld seam one by one using handheld equipment is inefficient and has a low degree of automation, which increases the labor intensity. To address this, a health status assessment device for hydropower equipment is proposed. Utility Model Content

Traditional methods for inspecting hydroelectric equipment, such as turbines and pipelines, often rely on manual inspection, which is inefficient, prone to missed inspections, susceptible to human factors, and unable to achieve real-time monitoring. Furthermore, manual inspection of individual welds is usually carried out by hand, which increases the labor intensity.
[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0007] The present invention is as follows: a health status assessment device for hydroelectric equipment, including a base, a detection mechanism for detecting the health status of hydroelectric equipment is provided on the top of the base, and two traveling components for facilitating automated detection are arranged opposite each other on one side of the detection mechanism;
[0008] The detection mechanism includes a mounting box fixedly connected to the top of the base. A battery is installed on one side of the bottom of the mounting box, and a PLC controller is installed on the other side of the bottom of the mounting box. An alarm is installed on the top of the mounting box, and a gas detector is installed on the bottom of the base. The alarm and gas detector are electrically connected to the PLC controller, and the PLC controller, alarm, and gas detector are electrically connected to the battery. Connectors are fixedly connected to both ends of the bottom of the base. Electric rollers are rotatably connected to the opposite side walls of the connectors. A first semicircular ring is slidably connected to the bottom of the base. A second semicircular ring is hinged to one end of the first semicircular ring. Sliding grooves are provided on the side walls of both the first and second semicircular rings and are slidably connected to the electric rollers.
[0009] As a preferred technical solution of this utility model, the traveling component includes a first spring fixedly connected to the bottom of the first semicircular ring, a C-shaped block fixedly connected to the bottom of the first spring, a limit rod fixedly connected to the top of the C-shaped block, a reserved groove opened at the bottom of the first semicircular ring and slidably connected to the limit rod, a micro motor fixedly connected to the side wall of the C-shaped block, and a hub fixedly connected to the output end of the micro motor.
[0010] As a preferred technical solution of this utility model, two second springs are fixedly connected to the outer walls of the first semicircular ring and the second semicircular ring. A splicing block is fixedly connected to the bottom of the two second springs. A rolling groove is opened at the bottom of the two splicing blocks, and a ball is rotatably connected inside the two rolling grooves.
[0011] As a preferred technical solution of this utility model, one end of the first semicircular ring is fixedly connected to two first magnetic blocks, and one end of the second semicircular ring is provided with two grooves, the bottom of the two grooves being fixedly connected to a second magnetic block.
[0012] As a preferred technical solution of this utility model, reserved holes are provided on the outer walls of both the first semicircular ring and the second semicircular ring.
[0013] As a preferred technical solution of this utility model, a motion control module is provided on one side of the PLC controller, and the motion control module is electrically connected to the PLC controller.
[0014] As a preferred technical solution of this utility model, anti-slip pads are provided on the outer walls of the two wheel hubs, and strip-shaped protrusions are provided on the surface of the anti-slip pads.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. Through the set detection mechanism, the device is first fixed to the outside of the pipe weld by the first and second semicircular rings. The inside of the pipe is filled with gas, and the electric roller is driven to roll along the slide groove, thereby driving the gas detector to move in a circle. It can detect whether there is a gas leak at the weld. If a gas leak is detected, the gas detector transmits a signal to the PLC controller, which activates the alarm to remind the inspection personnel. The detection covers the entire circumferential area of the weld, avoiding blind spots in fixed point detection and ensuring that no leak point is missed.
[0017] 2. Through the set travel component, when the first and second semicircular rings are fixed to the outside of the pipe, a ring structure is formed. The first spring is compressed, pushing the C-shaped block to move downward, so that the hub is close to the surface of the pipe. After the micro motor is powered on, the output end drives the hub to rotate, generating propulsion force, thereby driving the first and second semicircular rings to move, and then driving the gas detector to move horizontally, realizing automated detection, improving detection efficiency, and realizing automated and high-precision health assessment of the weld seams of the water turbine pipeline.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0028] like Figure 1 As shown, this embodiment proposes a health status assessment device for hydroelectric equipment, including a base 1. A detection mechanism 2 for detecting the health status of hydroelectric equipment is provided on the top of the base 1. Two traveling components 3 for facilitating automated detection are arranged opposite each other on one side of the detection mechanism 2.
[0029] like Figure 3 and Figure 4As shown, the detection mechanism 2 includes a mounting box 201 fixedly connected to the top of the base 1. A battery 202 is installed on one side of the bottom of the mounting box 201, and a PLC controller 203 is installed on the other side of the bottom of the mounting box 201. An alarm 204 is installed on the top of the mounting box 201, and a gas detector 205 is installed on the bottom of the base 1. The gas detector 205 monitors in real time whether there is a gas leak at the pipe weld. The PLC controller 203 is a data processing center that receives signals from the gas detector 205. The alarm 204 can remotely transmit signals to the monitoring center to achieve real-time early warning and prompt maintenance. With personnel intervention, the storage battery 202 provides mobile power to ensure the device can operate independently in environments without external power. The alarm 204 and gas detector 205 are electrically connected to the PLC controller 203. The PLC controller 203, alarm 204, and gas detector 205 are also electrically connected to the storage battery 202. Connecting pieces 206 are fixedly connected to both ends of the bottom of the base 1. Electric rollers 207 are rotatably connected to the opposite side walls of the connecting pieces 206. A first semi-circular ring 208 is slidably connected to the bottom of the base 1. A second semi-circular ring 209 is hinged to one end of the first semi-circular ring 208. Designed for easy and quick installation and disassembly, both the first semicircular ring 208 and the second semicircular ring 209 have grooves 210 on their side walls, which are slidably connected to the electric roller 207. The electric roller 207, controlled by a PLC for speed and direction, cooperates with the groove 210 of the first semicircular ring 208 to provide guidance and traction, ensuring the device moves along a predetermined path. The groove 210 provides a rolling track for the electric roller 207, ensuring precise movement and enhancing the fit between the device and the pipeline. In use, the device is first fixed to the outside of the pipeline weld using the first semicircular ring 208 and the second semicircular ring 209. The gas detector 205 is moved in a circular motion by filling the inside of the pipe with gas, which drives the electric roller 207 to roll along the slide groove 210. This motion detects whether there is a gas leak at the weld. If a leak is detected, the gas detector 205 transmits a signal to the PLC controller 203, which then activates the alarm 204 to alert the inspectors. The gas detector covers the entire circumferential area of the weld, avoiding blind spots in fixed-point detection and ensuring that no leaks are missed. The PLC analyzes the data in real time, avoiding errors from manual recording and improving detection accuracy.
[0030] like Figure 5As shown, the traveling component 3 includes a first spring 301 fixedly connected to the bottom of the first semicircular ring 208. The first spring 301 absorbs pipe diameter errors and surface irregularities through compression and extension, ensuring that the hub 306 always fits tightly against the pipe surface. A U-shaped block 302 is fixedly connected to the bottom of the first spring 301. The U-shaped block 302 directly transmits the rotational torque of the micro motor 305 to the hub 306, ensuring power transmission efficiency and reducing energy loss. A limit rod 303 is fixedly connected to the top of the U-shaped block 302. The limit rod 303 and the reserved groove 304 restrict the U-shaped block 302 to move only in the vertical direction, preventing the U-shaped block 302 from shifting laterally or rotating when the first spring 301 deforms. The bottom of the first semicircular ring 208 has a reserved groove 304, which is slidably connected to the limit rod 303. A micro motor 305 is fixedly connected to the side wall, and a hub 306 is fixedly connected to the output end of the micro motor 305. The hub 306 directly contacts the pipe surface and generates propulsion force through rotation, driving the first semi-circular ring 208 and the second semi-circular ring 209 to move along the pipe. When the first semi-circular ring 208 and the second semi-circular ring 209 are fixed to the outside of the pipe, they form a ring structure. The first spring 301 is compressed, pushing the C-shaped block 302 to move downward, so that the hub 306 is in close contact with the pipe surface. After the micro motor 305 is energized, the output end drives the hub 306 to rotate, generating propulsion force, thereby driving the first semi-circular ring 208 and the second semi-circular ring 209 to move, and then driving the gas detector 205 to move horizontally, realizing automated detection, improving detection efficiency, and realizing automated and high-precision health assessment of the weld seams of the water turbine pipeline.
[0031] like Figure 1 As shown, two second springs 4 are fixedly connected to the outer walls of the first semicircular ring 208 and the second semicircular ring 209. The bottom of the two second springs 4 is fixedly connected to the splicing block 5. The bottom of the two splicing block 5 is provided with a rolling groove 6. The inside of the two rolling grooves 6 is rotatably connected to a ball 7. The compression and extension characteristics of the second springs 4 enable the ball 7 to automatically adapt to the slight changes in the pipe diameter and the surface unevenness, ensuring that the ball 7 always keeps in contact with the pipe surface and avoids the device from tilting or vibrating due to local suspension.
[0032] like Figure 2 As shown, one end of the first semicircular ring 208 is fixedly connected to two first magnetic blocks 8, and one end of the second semicircular ring 209 has two grooves 9. The bottom of the two grooves 9 is fixedly connected to a second magnetic block 10. The first magnetic block 8 at the end of the first semicircular ring 208 and the second magnetic block 10 are magnetically attracted to each other, realizing the quick closing of the first semicircular ring 208 and the second semicircular ring 209 without the need for complex mechanical locking, thus simplifying the installation process.
[0033] like Figure 1As shown, reserved holes 11 are provided on the outer walls of the first semicircular ring 208 and the second semicircular ring 209. The reserved holes 11 provide space for the gas detector 205, shorten the detection path, ensure that the leaked gas is captured first, and avoid missed detection due to obstruction by the device structure.
[0034] like Figure 2 As shown, a motion control module 12 is provided on one side of the PLC controller 203. The motion control module 12 is electrically connected to the PLC controller 203 to ensure that the electric roller 207 moves along the preset path of the slide 210 through the programming of the PLC controller 203, thereby reducing manual intervention and realizing automated detection.
[0035] like Figure 1 As shown, anti-slip pads 13 are provided on the outer walls of the two hubs 306. Strip-shaped protrusions 14 are provided on the surface of the anti-slip pads 13. The anti-slip pads 13 are made of a high coefficient of friction material. Through the viscoelastic properties of the material itself, the static friction with the surface of the metal pipe is increased, preventing the hubs 306 from spinning or slipping. The arrangement direction of the strip-shaped protrusions 14 is perpendicular to the rotation direction of the hubs 306, effectively resisting the tangential force generated when the pipe moves axially, and preventing the device from undergoing longitudinal displacement due to inertia.
[0036] Specifically, when using this hydroelectric equipment health status assessment device: First, it is programmed via PLC controller 203. Then, the inside of the pipe is filled with gas. The device is fixed to the outside of the pipe weld seam via the first semicircular ring 208 and the second semicircular ring 209, forming a ring structure. The first spring 301 is compressed, pushing the U-shaped block 302 downward, so that the hub 306 is pressed tightly against the pipe surface. After the micro motor 305 is energized, the output end drives the hub 306 to rotate, generating propulsion force (such as...). Figure 5 As shown), this causes the first semi-circular ring 208 and the second semi-circular ring 209 to move, which in turn causes the gas detector 205 to move horizontally along the pipeline. The motion control module 12 and the battery 202 drive the electric roller 207 to roll along the slide groove 210, thereby causing the gas detector 205 to move in a circular motion. This allows for automated detection on the outer wall of the pipeline. If a leak is detected, the gas detector 205 transmits a signal to the PLC controller 203, which then activates the alarm 204 to alert the inspection personnel (e.g., ...). Figure 3 and Figure 4 If the value shown is positive, it indicates that the turbine pipeline is in poor health, with cracks or damage; conversely, it indicates that the turbine pipeline is in good health.
[0037] All technical features in this embodiment can be freely combined according to actual needs.
[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
