Description

Technical Field

[0001] This utility model relates to the field of hydropower station equipment inspection technology, and in particular to a clamping mechanism and a monitoring device for hydropower stations. Background Technology

[0002] In hydropower stations, temperature monitoring of critical equipment such as shaft seals and junction boxes is of paramount importance.

[0003] Traditional manual inspection methods involve inspectors using handheld temperature guns to measure the temperature of equipment. This is not only costly and inefficient, but also poses safety risks, especially in high-temperature or hazardous environments.

[0004] Fixed sensor monitoring systems need to be fixed in a certain location and rely on their own installed sensors, which include resistance temperature detectors (RTDs), thermocouples, and infrared sensors to detect temperature. Moreover, they lack flexibility when adding monitoring points, are difficult to adapt to changes in equipment layout, and their internal electronic components are easily damaged in high-temperature environments.

[0005] Semi-automatic track-based monitoring systems monitor required equipment by moving along a track, but the monitoring range is limited by the track, and efficiency is limited in narrow or obstacle-filled areas, with high track maintenance costs. A clamping mechanism holds the temperature measuring gun for temperature measurement.

[0006] In contrast, the gripping mechanism on the robot has significant advantages. Its installation process is simple, requiring no complex track system, thus reducing installation costs and difficulty. The gripping mechanism can quickly add monitoring points for real-time monitoring and is highly adaptable, capable of handling various complex environments. Utility Model Content

[0007] In view of the above-mentioned problems in the prior art, this utility model is proposed.

[0008] The purpose of this utility model is to provide a clamping mechanism, which aims to solve the problems of high cost and low efficiency caused by the reliance on tools such as temperature guns in traditional manual inspection methods. At the same time, the internal electronic components of the fixed sensor monitoring system are easily damaged in high-temperature environments.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: the fixing unit includes a base plate and a U-shaped block disposed above the base plate;

[0010] The support unit includes a support component disposed above the U-shaped block, a connecting component disposed at one end of the support component, a transmission component disposed on both sides of the connecting component, and a gripper disposed at one end of the transmission component.

[0011] As a preferred embodiment of the clamping mechanism of this utility model, the support component includes a first robotic arm disposed above the U-shaped block, a first driving member disposed on one side of the U-shaped block, a second robotic arm disposed at one end of the first robotic arm, a second driving member disposed inside the first robotic arm, a third robotic arm disposed at one end of the second robotic arm, a third driving member disposed inside the output end of the second robotic arm, and a radar disposed inside the third robotic arm.

[0014] As a preferred embodiment of the clamping mechanism of this utility model, one end of the first driving member is fixedly connected to the base plate;

[0015] Furthermore, the output end of the first drive component is fixedly connected to the first robotic arm.

[0016] One end of the second drive component is fixedly connected to one side of the first robotic arm;

[0018] One end of the third driving component is fixedly connected to one side of the second robotic arm;

[0019] Furthermore, the output end of the third drive component is fixedly connected to the third robotic arm.

[0020] The advantages of the clamping mechanism of this utility model are as follows: Through a motor-driven gear and rack transmission device and a gripper structure, the clamping mechanism can automatically adapt to temperature measuring components of different shapes and sizes, improving temperature measurement accuracy and stability. This clamping mechanism has a simple mechanical structure and no internal precision components. In high-temperature environments, it relies solely on mechanical transmission to clamp the temperature measuring component, making it unaffected by the high-temperature environment. Furthermore, its compact structure and ease of maintenance meet the monitoring needs of different scenarios; it significantly reduces reliance on manual inspection, saving labor costs.

[0021] Another objective of this invention is to provide a monitoring device for hydropower stations, which aims to solve the problems of insufficient flexibility of traditional fixed sensors when additional monitoring points are needed, the limited efficiency of semi-automatic track-based monitoring systems due to track limitations in narrow or obstacle-filled areas, and high track maintenance costs.

[0022] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: the moving unit includes a housing, a locking component disposed on the housing, and a rotating component disposed below the housing.

[0023] As a preferred embodiment of the monitoring device for hydropower stations according to this utility model, the box body includes a shell, a hinge disposed on one side of the shell, a door disposed on one side of the shell, and a crossbar disposed on the door.

[0025] As a preferred embodiment of the monitoring device for hydropower stations of this utility model, the rotating component includes a base disposed below the housing and casters disposed below the base.

[0026] As a preferred embodiment of the monitoring device for hydropower stations of this utility model, the limiting plate is provided with a slot, and a positioning pin is provided on the limiting plate.

[0027] The beneficial effects of this utility model's monitoring device for hydropower stations are as follows: Through its rotatable mobile unit, the monitoring device can easily adapt to changes in equipment layout within the hydropower station or the need for adding new monitoring points. Without the need for complex reinstallation or wiring adjustments, rapid deployment and adjustment of monitoring points can be achieved, greatly improving the flexibility and adaptability of the monitoring system.

[0062] Example 3

[0063] Reference Figures 1 to 7 This is the third embodiment of the present invention, which further provides a monitoring device for a hydropower station. The moving unit 3 includes a housing 31, a locking assembly 32 disposed on the housing 31, and a rotating assembly 33 disposed below the housing 31.

[0064] Furthermore, the housing 31 includes a shell 311, a hinge 312 disposed on one side of the shell 311, a door 313 disposed on one side of the shell 311, and a crossbar 314 disposed on the door 313.

[0065] Furthermore, the locking assembly 32 includes a support block 321 disposed on one side of the housing 31, a groove 322 disposed on the support block 321, a spring 323 disposed in the groove 322, and a limiting plate 324 disposed in the support block 321.

[0066] Furthermore, the rotating assembly 33 includes a base 331 disposed below the housing 31, and casters 332 disposed below the base 331.

[0067] Furthermore, a bayonet 3241 is provided on the limiting plate 324, and a positioning pin 3242 is provided on the limiting plate 324.

[0068] It should be noted that the housing 311 is connected to the door 313 via a hinge 312. The crossbar 314 is fixed to one side of the door 313 and works in conjunction with the locking assembly 32. One side of the support block 321 in the locking assembly 32 is fixedly connected to the housing 311. The support block 321 has a V-shaped groove and an internal groove 322. A spring 323 is installed in the groove 322. One end of the spring 323 is fixed in the groove 322 and the other end presses against the limiting plate 324. The limiting plate 324 has a positioning hole 3242 and is connected to the support block 321 through the positioning hole 3242. The rotating assembly 33 is located below the housing 31, and the universal wheel 332 is located inside the base 331. The output end of the universal wheel 332 is fixedly connected to the bottom of the housing 31.

[0069] In use, the door 313 is connected to the housing 311 via hinge 312, ensuring that the door 313 can be opened and closed. A crossbar 314 is fixed to one side of the door 313 and works in conjunction with the locking assembly 32 to ensure that the door 313 can be locked when closed.

[0070] When the door 313 is closed, the locking assembly 32 begins to function. A support block 321 is fixedly connected to one side of the housing 311, and a spring 323 is housed within a groove 322 on it. One end of the spring 323 is fixed in the groove 322, while the other end abuts against a limiting plate 324. The limiting plate 324 has a latch 3241 and a positioning hole 3242. The latch 3241 engages with the crossbar 314 on the door 313, while the positioning hole 3242 ensures the stable position of the limiting plate 324 on the support block 321. When the door 313 is closed, the crossbar 314 is pressed into the latch 3241, and the spring force of the spring 323 pushes the limiting plate 324 against the door 313, thus securely locking the door. If it is necessary to unlock the cabinet door 313, the operator only needs to apply a little external force to separate the latch 3241 on the limit plate 324 from the crossbar 314, and the cabinet door can be opened; the elastic force of the spring 323 will help the limit plate 324 return to its original position.

[0071] The moving unit 3 is also equipped with a rotating assembly 33 to facilitate operation of the monitoring device at different angles or positions. The rotating assembly 33 includes a base 331 disposed below the housing 31 and casters 332 disposed inside the base 331. The output end of the casters 332 is fixedly connected to the bottom of the housing 31, and the orientation or position of the housing 31 can be adjusted by rotating the casters 332.

[0072] In summary, the hinged enclosure door can be easily opened and closed, facilitating maintenance and replacement of the internal monitoring equipment. A locking mechanism ensures the door's stability when closed, and the combination of a spring and a limit plate locks the door securely. The orientation or position of the monitoring device for hydropower stations can be easily adjusted using the casters at the bottom of the rotating base to adapt to changes in equipment layout or the need for new monitoring points. This improves the flexibility and adaptability of the monitoring device, making the deployment and adjustment of monitoring points quick and easy. Simultaneously, the integrated mobile unit houses the monitoring equipment within the enclosure, reducing external wiring, simplifying installation, and lowering maintenance costs and complexity.
