Description

Technical Field

[0001] This utility model relates to the field of equipment protection technology, and in particular to a protection mechanism and a fault diagnosis device for hydropower units. Background Technology

[0002] Hydropower unit fault diagnosis equipment is an intelligent system specifically designed to monitor, analyze, and provide early warnings of the operating status of hydropower generator units. It collects key mechanical, electrical, and hydraulic parameters and combines them with intelligent algorithms to determine the equipment's health status, enabling early warning and precise fault location. Currently, the technology for hydropower unit fault diagnosis equipment is quite mature. However, in practical applications, portable diagnostic devices still have some design flaws that affect ease of use and equipment safety. Specifically, these devices typically require the use of temperature and vibration sensors, current transformers, and other detection terminals for diagnosis. These terminals are often installed on the generator using magnetic attachment or cable clamps.

[0003] During carrying and transportation, due to the lack of dedicated storage space, these precision testing devices are prone to bumps and knocks due to careless placement, which can lead to problems such as sensor probe deformation, interface damage, or magnetic component detachment. The bottom of existing diagnostic equipment generally does not have an anti-slip positioning structure. When the equipment is placed on an uneven surface or subjected to a slight impact, it is very easy to slide or even fall. This may not only cause physical damage such as cracking of the equipment shell and screen damage, but may also cause failure of internal precision electronic components, seriously affecting the testing accuracy and service life of the equipment.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the technical problem that existing fault diagnosis equipment is at risk of damage during transport and placement, this utility model is proposed.

[0006] The purpose of this invention is to provide a protective mechanism that addresses the problem of insufficient protection in existing diagnostic equipment protective structures.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective mechanism, comprising a protective box, the top of which is provided with a flip-top; and,

[0008] Storage components are provided on the side of the protective box and stabilizing components are provided on the bottom of the protective box.

[0009] As a preferred embodiment of the protective mechanism of this utility model, the storage component includes a folding shell disposed on the side of the protective box, and the top of the folding shell is provided with a retractable structure.

[0010] As a preferred embodiment of the protective mechanism of this utility model, the retractable structure includes a protective plate disposed on the side of the protective box, a gear shaft disposed at the bottom of the protective plate, a retaining ring disposed on the outer wall of the gear shaft, and a torsion shaft disposed at one end of the gear shaft.

[0011] As a preferred embodiment of the protective mechanism of this utility model, a locking rod is provided on the side of the torsion shaft, and the end of the locking rod away from the torsion shaft is connected to the retaining ring.

[0027] 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.

[0028] 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.

[0029] 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 or selective embodiment that excludes other embodiments.

[0030] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention, which provides a protective mechanism including a protective box 11. The top of the protective box 11 is provided with a flip cover 12, which can cover the protective box 11 to form a closed space, protecting the diagnostic equipment inside the protective box 11. Preferably, a connecting structure can be provided between the flip cover 12 and the protective box 11 for locking; and...

[0031] The storage component 13 is located on the side of the protective box 11, and the precision detection ends such as sensor probes are located inside the storage component 13. The stabilizing component 14 is located at the bottom of the protective box 11. When the device is placed, the stabilizing component 14 will provide an anti-slip connection to the bottom of the device, making the device more stable in the diagnostic area and preventing it from sliding or even falling and damaging the diagnostic components.

[0032] Furthermore, the storage component 13 includes a folding shell 131 disposed on the side of the protective box 11. The folding shell 131 is a structure composed of multiple folding panels similar to an accordion. It can be folded up for storage or stretched out. Connecting wires and detection probes are placed inside the folding shell 131. A retractable structure 132 is provided on the top of the folding shell 131.

[0033] Furthermore, the retractable structure 132 includes a protective plate 134 disposed on the side of the protective box 11. A gear shaft 136 is disposed at the bottom of the protective plate 134. A retaining ring 138 is disposed on the outer wall of the gear shaft 136. The outer side of the retaining ring 138 is fixedly connected to the bottom of the protective plate 134. A torsion shaft 137 is disposed at one end of the gear shaft 136. A locking rod 139 is disposed on the side of the torsion shaft 137. The end of the locking rod 139 away from the torsion shaft 137 is connected to the retaining ring 138. An L-shaped plate 133 is disposed at the end of the folding shell 131 away from the protective box 11. A cover plate is also disposed at the end of the folding shell 131 away from the protective box 11. The bottom of the L-shaped plate is connected to the cover plate. The top of the L-shaped plate 133 is in contact with the bottom of the protective plate 134. A toothed groove 135 is opened at the bottom of the L-shaped plate 133. The toothed groove 135 meshes with the gear on the gear shaft 136.

[0034] Usage: When storing diagnostic probes, connecting cables, and other components, place these parts in the folding housing 131, then close the cover. At this time, the L-shaped plate 133 will be parallel to the protective plate 134. Extend the L-shaped plate 133 under the protective plate 134 so that the toothed groove 135 at the bottom of the L-shaped plate 133 meshes with the gear shaft 136. Then, rotate the torsion shaft 137 to drive the gear shaft 136 to rotate. The rotation of the gear will cause the L-shaped plate 133 to slide towards the protective plate 134, moving the folding box towards the protective box 11. The folding box is folded and tightened against the outer wall of the protective box 11, which can well store connecting cables, diagnostic probes, and other components. At this time, inserting the locking rod 139 into the retaining ring 138 will tighten the torsion shaft 136. The rotating shaft 137 is connected to the retaining ring 138. Since the retaining ring 138 is fixedly connected to the protective plate 134, the rotating shaft 137 is locked and cannot rotate. Thus, the folding outer shell 131 is locked and cannot be easily opened. Furthermore, using the folding box to store parts can reduce the size of the equipment. When diagnosing the hydro-generator set, the locking rod 139 can be removed. At this time, the rotating shaft 137 can be rotated to drive the gear shaft 136 to rotate, which can drive the L-shaped plate 133 away from the protective plate 134 and drive the folding outer shell 131 away from the protective box 11 until the L-shaped plate 133 is completely detached from the protective plate 134. Then the folding outer shell 131 can be opened, and diagnostic probes, connecting wires, and other parts can be taken out for diagnosis.

[0035] Example 2, refer to Figures 1-5 This is the second embodiment of the present invention. Unlike the previous embodiment, the stabilizing member 14 includes a driven bevel gear 141 disposed at the bottom of the protective box 11. A threaded rod 142 is disposed at the bottom of the driven bevel gear 141. Preferably, the top of the driven bevel gear 141 is rotatably connected to the bottom of the protective box 11, and the driven bevel gear 141 is fixedly connected to the threaded rod 142. The driven bevel gear 141 and the threaded rod 142 together can rotate relative to the protective box 11. A connecting frame 143 is disposed on the outer wall of the threaded rod 142, and a silicone disc 144 is disposed on the side of the connecting frame 143. Figure 5 As shown, a threaded hole is provided in the middle of the connecting frame 143. The middle of the connecting frame 143 is threadedly connected to the outer wall of the threaded rod 142. The connecting frame 143 is I-shaped. The outer end of the connecting frame 143 is fixedly connected to the silicone disc 144. The silicone disc 144 is fitted on the bottom of the protective box 11 and can slide up and down on the bottom of the protective box 11.

[0036] Furthermore, the top of the silicone disc 144 is connected to the bottom of the protective box 11. The bottom of the protective box 11 is provided with a drive gear shaft 145, which meshes with the driven bevel gear 141. Rotating the drive gear shaft 145 can drive the driven bevel gear 141 to rotate, which in turn drives the threaded rod 142 to rotate. Thus, the connecting frame 143 will drive the silicone disc 144 to rise and fall together under the action of the threaded rod 142.

[0037] Usage: When using the diagnostic equipment, it is necessary to set up the equipment. When setting up the equipment, the drive gear shaft 145 can be rotated to drive the threaded rod 142 to rotate, so that the connecting frame 143 moves away from the protective box 11 under the action of the threaded rod 142, and the silicone disc 144 moves away from the protective box 11 at the same time. The silicone disc 144 extends out from the bottom of the protective box 11. At this time, pressure can be applied to the silicone disc 144 to squeeze out the air inside, so that the silicone disc 144 can be tightly attached to the surface to be set up to prevent it from slipping during use. After the diagnosis is completed, rotating the gear shaft 136 in the opposite direction can drive the threaded rod 142 to rotate in the opposite direction, so that the connecting frame 143 moves closer to the protective box 11, so that the silicone disc 144 is retracted to the bottom of the protective box 11 for easy carrying and transportation.

[0038] Example 3, referring to Figures 1-5 This is the third embodiment of the present invention, which further provides a fault diagnosis device for hydropower units. Including the aforementioned protective mechanism, it also includes a diagnostic instrument 2, which includes an analyzer 21. An operation panel 22 is provided on the top of the analyzer 21, and the diagnostic instrument 2 also includes a pad 23 disposed on the top of the operation panel 22.

[0039] The analyzer 21 analyzes the data collected by the diagnostic probe. The diagnostic personnel interact with the analyzer 21 through the operation panel 22. The pad 23 is made of soft rubber and provides protection for the operation panel 22 when the flip cover 12 is closed.
