Description

Technical Field

[0001] This utility model relates to the field of hydropower unit technology, and in particular to an adjustable mechanism and a hydropower unit operation data acquisition device. Background Technology

[0002] Hydropower units are the core equipment of hydropower stations, and their operating status directly affects the efficiency and safety of power production.

[0003] However, existing hydropower unit operation data acquisition devices have several shortcomings. Firstly, the sensors are fixed in location, making it impossible to flexibly adjust the monitoring and acquisition positions according to actual needs. This limits data collection to specific areas, failing to cover the overall operating status of the unit and resulting in inaccurate reflection of parameter differences across locations, thus hindering a comprehensive assessment of the hydropower unit's true operating condition. Secondly, most existing data acquisition devices lack effective lighting, or the lighting is installed at an inappropriate height. In low-light conditions at night or in poor lighting environments, insufficient illumination can lead to operational errors, increasing safety risks for personnel and causing significant inconvenience for equipment maintenance and data acquisition. Furthermore, wind direction sensors suffer from similar issues; lower installation heights are susceptible to interference from ground obstacles, resulting in inaccurate wind direction data that fails to accurately reflect the wind conditions in the unit's operating environment, thus affecting the accurate analysis of the hydropower unit's operating environment.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0027] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention. This embodiment provides an adjustable mechanism that can adaptively adjust the monitoring position of the hydropower unit through the design of the cooperation between the moving component and the guiding component, thereby expanding the monitoring and data collection range of the unit.

[0028] Specifically, it includes a support component 1, a guide component 2 disposed on the top of the support component 1, a movable component 3 movably connected to the top of the guide component 2, a lifting component 4 fixedly disposed on the lifting component 4, and several sets of installation components 5 fixedly disposed on the lifting component 4.

[0029] Furthermore, the moving component 3 includes an adjustment part 31, a support plate 32 disposed on the adjustment part 31, four sets of guide wheels 34 fixedly disposed on the lower end of the support plate 32, a fixing plate 35 fixedly disposed on the lower end of the support plate 32, a limiting block 36 fixedly disposed on the fixing plate 35, and a camera 37 disposed on the bottom of the fixing plate 35.

[0030] Ideally, cameras are used for video monitoring of hydropower units, providing intuitive operational status information and assisting in monitoring and maintenance.

[0031] Furthermore, the adjustment unit 31 includes a housing 311 disposed on the upper end of the support plate 32, a first motor 312 disposed on the outside of the housing 311, a first bevel gear 313 fixedly connected to the first motor 312, a second bevel gear 314 meshing with the first bevel gear 313, a rotating rod 315 disposed on the second bevel gear 314, and a drive gear 316 fixedly connected to one end of the rotating rod 315 away from the second bevel gear 314; both the first bevel gear 313 and the second bevel gear 314 are disposed inside the housing 311.

[0032] Furthermore, the guide assembly 2 includes a guide frame 21, guide rails 22 fixedly disposed on both sides of the guide frame 21, a guide groove 23 opened on the guide frame 21, a toothed block 24 fixedly disposed on the side wall of the guide groove 23, and a limiting groove 25 opened at the end of the guide groove 23 away from the toothed block 24; the toothed block 24 meshes with the drive gear 316, the limiting groove 25 is slidably connected to the limiting block 36, and the four sets of guide wheels 34 all cooperate with the guide rails 22.

[0033] It should be noted that the design of the limiting groove 25 cooperating with the limiting block 36 and the design of the guide wheel 34 cooperating with the guide rail 22 ensures that the moving component 3 moves stably on the guide frame 21. At the same time, the limiting groove 25 plays a limiting role, preventing misalignment between the drive gear 316 and the tooth block 24, and preventing the guide wheel 34 from derailing on the guide rail 22. The fixing plate 35 is U-shaped, with the top two ends of the fixing plate 35 fixedly connected to the bottom of the support plate 32, forming a cavity in the middle to accommodate the guide component 2. The advantage of this design is that it allows the moving component 3 to have a more stable moving space.

[0034] Furthermore, the support assembly 1 includes a base 11 and support frames 12 respectively fixedly disposed on both sides of the base 11; the support frames 12 are fixedly connected to the guide frame 21.

[0035] Furthermore, the lifting assembly 4 includes a support base 41, a sleeve rod 42 fixedly disposed on the upper end of the support base 41, a drive part 43 fixedly disposed on the sleeve rod 42, a guide rod 44 sleeved on the sleeve rod 42, a toothed plate 45 fixedly connected to the guide rod 44, a support plate 46 fixedly connected to the guide rod 44, and a top cover 48 fixedly disposed on the support plate 46.

[0036] Furthermore, the drive unit 43 includes a protective shell 431 disposed on the sleeve rod 42, a connecting gear 432 disposed inside the protective shell 431, and a second motor 433 interconnected with the connecting gear 432; the connecting gear 432 cooperates with the toothed plate 45.

[0037] Furthermore, the mounting assembly 5 includes a connecting frame 51 mounted on the support plate 46, a limiting frame 52 mounted on the connecting frame 51, a mounting block 53 disposed inside the limiting frame 52, a mounting hole 54 disposed on the mounting block 53, a lighting lamp 55 disposed on the mounting block 53, a limiting rod 56 inserted into the limiting frame 52, a fixing block 57 inserted into the limiting rod 56, a spring 58 disposed on the fixing block 57, and a limiting plate 59 disposed on the spring 58.

[0038] Preferably, the purpose of the lighting 55 is to provide sufficient illumination for inspections, equipment maintenance, or data collection at night or in low-light environments.

[0039] It should be noted that the low installation height of the lighting lamp 55 directly illuminates a localized area of ​​the ground or equipment, but it is difficult to provide sufficient overall lighting, requiring frequent repositioning of the lamp. A higher installation height of the lighting lamp 55 provides a wider lighting range, reduces shadow areas, and improves operational safety and convenience. By inserting the mounting block 53 into the limiting bracket 52 and then inserting the limiting rod 56 into the mounting hole 54, the limiting rod 56 is securely inserted into the mounting hole 54 under the elastic force of the spring 58, thus achieving rapid installation of the lighting lamp 55. When it is necessary to replace or repair the lighting lamp 55, simply pull the limiting rod 56 away from the fixing block 57 to remove it from the mounting hole 54. This structural design, where the limiting rod is spring-loaded into the mounting hole, enables rapid installation and removal of the lighting lamp, facilitating equipment replacement and maintenance, and improving equipment maintainability.

[0040] In operation, starting the first motor 312 drives the first bevel gear 313 to rotate, which in turn drives the second bevel gear 314 to rotate. The second bevel gear 314 and the drive gear 316 are coaxial. Therefore, driven by the second bevel gear 314, the drive gear 315 moves along the tooth block 24 within the guide groove 23. The position of the drive gear 315 within the guide groove 23 is adjusted via the control panel 334, thereby adjusting the monitoring position of the hydroelectric generator. Starting the second motor 433 drives the connecting gear 432 to rotate. The toothed plate 45 engages with the connecting gear 432, causing the connecting gear 432 to move the toothed plate 45 up and down within the sleeve rod 42, thus moving the lighting lamp 55 to achieve height adjustment.

[0041] Example 2, refer to Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the monitoring component 33 and the wind direction sensor 47 disposed on the support plate 46.

[0042] Furthermore, the monitoring component 33 includes a mounting bracket 331 disposed on the upper end of the support plate 32, an acoustic sensor 332 disposed on the mounting bracket 331, a temperature sensor 333 disposed on the mounting bracket 331, and a control panel 334 fixedly disposed on the upper end of the support plate 32.

[0043] Preferably, the control panel 334 is used to control the operation and manage the data of the entire unit. The acoustic sensor 332 is used to monitor the unit noise, and the temperature sensor 333 is used to monitor the unit temperature, providing data support for the evaluation of the hydropower unit's operating status. Both the acoustic sensor 332 and the temperature sensor 333 collect data from the unit through a detection probe at one end of the detection line.

[0044] It should be noted that the wind direction sensor 47 is used to monitor the ambient wind direction. Because the wind direction sensor 47 is installed at a low height, it is susceptible to interference from ground obstacles, leading to inaccurate wind direction data and failing to accurately reflect the wind direction conditions of the unit's operating environment. If installed at a higher height, it can more accurately monitor the wind direction in the free wind field, providing more reliable data support for the analysis of the hydropower unit's operating environment. Therefore, by designing a drive unit on the lifting assembly, the heights of both the lighting fixture and the wind direction sensor can be adjusted simultaneously.

[0045] In use, the second motor 433 is started to drive the connecting gear 432 to rotate. The toothed plate 45 and the connecting gear 432 cooperate with each other, so the connecting gear 432 drives the toothed plate 45 to move up and down in the sleeve rod 42, thereby driving the wind direction sensor 47 to move to achieve height adjustment.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
