Detailed Implementation

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0037] It should be understood that the terms "before" and "after" are used in this utility model to describe various types of information, but these terms should not be limited to them. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this utility model.

[0038] like Figures 1 to 8 As shown, a stress wave signal monitoring device 100 according to an embodiment of the present invention includes a telescopic device 10 and a stress wave monitoring device 20. The telescopic device 10 includes a telescopic mechanism 11 extending along a first direction, which is parallel to the vertical direction. The stress wave monitoring device 20 includes a cabinet 21, a stress wave acquisition mechanism 22, and a position adjustment mechanism 23. The cabinet 21 is located on the top of the telescopic device 10, and a mounting cavity 211 with an opening 212 on one side is formed inside the cabinet 21. The position adjustment mechanism 23 is located in the mounting cavity 211 and is drivenly connected to the stress wave acquisition mechanism 22. The position adjustment mechanism 23 is used to output power to the stress wave acquisition mechanism 22 so that the stress wave acquisition mechanism 22 can extend toward the opening 212.

[0039] Furthermore, in some embodiments, the stress wave monitoring device 20 includes a cabinet 21, a stress wave acquisition mechanism 22, and a position adjustment mechanism 23. The cabinet 21 is located on top of the telescopic device 10, and a mounting cavity 211 with an opening 212 on one side is formed inside the cabinet 21. The stress wave acquisition mechanism 22 is movably disposed in the mounting cavity 211. The position adjustment mechanism 23 includes a limiting component 231 and a driving component 232. The limiting component 231 is movably disposed in the mounting cavity 211 and has a first position and a second position. The driving component 232 is drivenly connected to the stress wave acquisition mechanism 22. When the limiting component 231 is in the first position, it abuts against the stress wave acquisition mechanism 22 to limit the displacement of the stress wave acquisition mechanism 22. When the limiting component 231 is in the second position, it disengages from the stress wave acquisition mechanism 22, and the driving component 232 drives the stress wave acquisition mechanism 22 to extend toward the opening 212.

[0040] The telescopic device 10 can drive the photovoltaic power generation device 30 and the stress wave monitoring device 20 to move up and down in the height direction. Under normal conditions, the stress wave signal detection device can lift the stress wave monitoring device 20 to a preset installation height via the telescopic device 10. When maintenance is required on the stress wave monitoring device 20, the stress wave signal detection device can lower the photovoltaic power generation device 30 to a lower position via the telescopic device 10, allowing maintenance personnel to perform maintenance operations on the ground. Furthermore, the stress wave monitoring device 20 includes a cabinet 21 with a mounting cavity 211, a stress wave acquisition mechanism 22, and a position adjustment mechanism 23. The position adjustment mechanism 23 is located inside the mounting cavity 211 and is driven and connected to the stress wave acquisition mechanism 22. When maintenance is required on the stress wave acquisition mechanism 22, the drive mechanism can push the stress wave acquisition mechanism 22 toward the opening 212, thereby adjusting the position of the stress wave acquisition mechanism 22 in the vertical and horizontal directions. Moreover, the overall structure of the stress wave signal monitoring device is simple, which helps to save on the manufacturing and installation costs of the stress wave signal monitoring device.

[0041] In one feasible embodiment, the telescopic device 10 can be configured as an electric telescopic rod, comprising at least two nested tubular structures. The interior of each tubular structure is hollow, and at least one tubular structure contains a drive mechanism. The drive mechanism can be configured as a screw drive mechanism, comprising a drive motor, a lead screw extending in a first direction, and a nut connected to the tubular structure. When the drive motor drives the lead screw to rotate, the nut can move axially along the lead screw, thereby pushing the connected tubular structure to move up and down. Thus, the drive mechanism can drive relative movement between two adjacent nested tubular structures, allowing the telescopic device 10 to switch between an extended and retracted state.

[0042] Specifically, two adjacent nested tube structures are designated as an inner tube and an outer tube, respectively. When the telescopic device 10 is in a retracted state, at least a portion of the inner tube near the outer tube can be embedded inside the outer tube, thereby reducing the top height of the overall structure of the telescopic device 10. When the telescopic device 10 is in an extended state, the inner tube can extend upward from the outer tube under the drive of the drive structure, thereby changing the telescopic device 10 from a retracted state to an extended state, thus increasing the top height of the overall structure of the telescopic device 10. Similarly, the inner tube can also move from the outside to the inside of the outer tube under the drive of the drive structure, thereby changing the telescopic device 10 from an extended state to a retracted state and increasing the volume of the inner tube embedded inside the outer tube, thereby reducing the top height of the overall structure of the telescopic device 10.

[0043] Furthermore, in some embodiments, the telescopic device 10 may also have a control panel on its bottom outer wall. The control panel may have a touch area for users to trigger control commands, allowing maintenance personnel to control the telescopic device 10 between extended and retracted states via a control terminal operated from the ground. Alternatively, in other embodiments, the stress wave signal monitoring device 100 may also include a control terminal communicatively connected to the telescopic device 10, allowing maintenance personnel to directly control the telescopic device 10 between extended and retracted states from the ground via the control terminal. Of course, the technical solution of this utility model is not limited to these embodiments, and specific implementations can be set according to actual needs.

[0044] In one feasible implementation, the stress wave acquisition mechanism 22 includes a vibrating wire sensor acquisition module. The vibrating wire sensor acquisition module can be an eight-channel vibrating wire sensor acquisition module with model number LZT-DA765-08 in the prior art, which has stable performance and multi-port channel reception and output functions, and is suitable for a variety of application scenarios.

[0045] like Figures 2 to 5As shown, the cabinet 21 of this embodiment of the present invention has an opening 212 on one side of the second direction, which is perpendicular to the first direction. The position adjustment mechanism 23 includes a limiting component 231 and a driving component 232. The limiting component 231 is movably disposed in the mounting cavity 211 and has a first position that abuts against the stress wave acquisition mechanism 22 and a second position that is disengaged from the stress wave acquisition mechanism 22. The driving component 232 is an elastic driving component, which is disposed on the side of the stress wave acquisition mechanism 22 away from the opening 212 and is elastically extended and retracted in the second direction so that when the limiting component 231 is in the second position, it drives the stress wave acquisition mechanism 22 to extend toward the opening 212.

[0046] Specifically, the drive assembly 232 is elastically telescopically configured in the second direction to have a contracted state and an extended state. When the stress wave acquisition mechanism 22 is housed within the mounting cavity 211, the limiting assembly 231 in the first position abuts against the stress wave acquisition mechanism 22 to limit the displacement of the stress wave acquisition mechanism 22 within the mounting cavity 211. At this time, the drive assembly 232 can be held in the contracted state by being pressed against by the stress wave acquisition mechanism 22. When the limiting assembly 231 moves to the second position, it disengages from the stress wave acquisition mechanism 22 to release the stress wave acquisition mechanism 22. At this time, the drive assembly 232 can release elastic potential energy and switch to the extended state, thereby applying elastic force to the stress wave acquisition mechanism 22 along the second direction toward the opening 212 to drive the stress wave acquisition mechanism 22 to extend toward the opening 212.

[0047] Optionally, in one feasible implementation, the drive assembly 232 can be configured as a resilient telescopic rod. For example... Figure 4 As shown, the elastic telescopic rod may include a nested outer tube and an inner tube. The outer tube has a hollow rod structure and is located within the mounting cavity 211, fixed to the side wall of the stress wave acquisition mechanism 22 away from the opening 212. One end of the inner tube is inserted into and confined inside the outer tube, while the other end abuts against the stress wave acquisition mechanism 22. The elastic telescopic rod also includes an elastic element, which may be specifically configured as a spring that elastically extends and retracts in a second direction. When the stress wave acquisition mechanism 22 and the inner tube are subjected to external force and extend into the outer tube, the spring can contract under force and accumulate elastic potential energy. When the stress wave acquisition mechanism 22 and the inner tube are not subjected to external force, the spring can drive the inner tube to extend the stress wave acquisition mechanism 22 toward the opening. Of course, the technical solution of this utility model is not limited to this, and the specific implementation can be set according to actual needs.

[0048] like Figures 2 to 5As shown, in this embodiment of the present invention, the limiting component 231 extends along a third direction, which is perpendicular to the first and second directions. The mounting cavity 211 has a limiting groove 213 on at least one side of the third direction. The limiting groove 213 extends along the first direction and is slidably connected to the end of the limiting component 231. When the limiting component 231 is in the first position, it is located at the lower end of the limiting groove 213 and stops on the side of the stress wave acquisition mechanism 22 facing the opening 212. When the limiting component 231 is in the second position, it is located at the upper end of the limiting groove 213 and is spaced apart from the top side of the stress wave acquisition mechanism 22.

[0049] Specifically, under normal conditions, the limiting component 231 is held at the lower end of the limiting groove 213 and in the first position under the action of gravity, thus blocking the stress wave acquisition mechanism 22 from the side facing the opening 212. When maintenance is required on the stress wave acquisition mechanism 22, the maintenance personnel can manually push the limiting component 231 upward to move it to the second position and disengage it from the stress wave acquisition mechanism 22. This releases the limiting component 231 from the stress wave acquisition mechanism 22, allowing the stress wave acquisition mechanism 22 to extend towards the opening 212 under the drive of the driving component 232, facilitating maintenance personnel to perform maintenance on the stress wave acquisition mechanism 22. After completing the maintenance of the stress wave acquisition mechanism 22, the maintenance personnel can first ensure that the limiting component 231 is manually pushed up to the second position, so that the stress wave acquisition mechanism 22 can be pushed into the mounting cavity 211 from below the limiting component 231. Then, the limiting component 231 is moved down to the first position. At this time, the limiting component 231 and the driving component 232 respectively abut against the opposite sides of the stress wave acquisition mechanism 22 in the second direction, so as to lock the stress wave acquisition mechanism 22 in the mounting cavity 211. This setting improves the ease of picking up and putting down the stress wave acquisition mechanism 22, making it easier for maintenance personnel to maintain the stress wave acquisition mechanism 22.

[0050] like Figures 2 to 5 As shown, the bottom wall of the mounting cavity 211 in this embodiment of the present invention is provided with a sliding groove 214. The sliding groove 214 extends along the second direction and connects to the opening 212. The stress wave acquisition mechanism 22 is located at the bottom of the mounting cavity 211 and slides in cooperation with the sliding groove 214. Thus, when the stress wave acquisition mechanism 22 moves relative to the cavity wall of the mounting cavity 211, the sliding groove 214 can guide and limit the stress wave acquisition mechanism 22, thereby helping to ensure the movement stability of the stress wave acquisition mechanism 22.

[0051] like Figures 2 to 5As shown, the stress wave acquisition mechanism 22 of this embodiment has a slider 221 on its bottom wall. One end of the slider 221 facing away from the stress wave acquisition mechanism 22 slides in conjunction with a groove 214. At least a portion of the slider 221 protrudes from the opening of the groove 214, so that the bottom wall of the stress wave acquisition mechanism 22 is spaced apart from the bottom wall of the mounting cavity 211. This arrangement reduces the contact area between the bottom wall of the stress wave acquisition mechanism 22 and the bottom wall of the mounting cavity 211, thereby improving the smoothness of the stress wave acquisition mechanism 22 when moving within the mounting cavity 211.

[0052] like Figures 6 to 8 As shown, the stress wave signal monitoring device 100 of this utility model embodiment also includes a photovoltaic power generation device 30 disposed on the top of the telescopic mechanism 11. The photovoltaic power generation device 30 includes a mounting base 31 and a photovoltaic power generation mechanism 32. The mounting base 31 is disposed on the top of the telescopic mechanism 11 and is detachably connected to the telescopic mechanism 11. The top side of the mounting base 31 has a mounting surface, which is inclined relative to the first direction. The photovoltaic power generation mechanism 32 is disposed on the mounting surface.

[0053] Specifically, the photovoltaic power generation mechanism 32 can be electrically connected to the stress wave monitoring device 20. The stress wave monitoring device 20 includes a power supply mechanism 24, which is located within the mounting cavity 211 of the cabinet 21 and above the stress wave acquisition mechanism 22. Optionally, in one feasible embodiment, the photovoltaic power generation mechanism 32 can use a solar module of model S48-3000 from the prior art. Specific implementation methods can be set according to actual needs and are not limited here.

[0054] like Figures 6 to 8 As shown, the telescopic mechanism 11 of this embodiment has a locking block 12 on its top side and a locking groove 311 on its bottom side. The locking block 12 engages with the locking groove 311 and is detachably connected to the mounting base 31. This arrangement improves the ease of assembly and disassembly of the photovoltaic power generation device 30.

[0055] like Figures 6 to 8 As shown, the card block 12 of this embodiment of the present invention is provided with a first connecting hole 121 on one side. The photovoltaic power generation device 30 also includes a connecting mechanism 33. The connecting mechanism 33 includes a rotating member 331 and a fastener. The rotating member 331 includes a first end and a second end arranged opposite to each other. The first end is rotatably connected to the mounting base 31. The second end is provided with a second connecting hole 331a. The second end is used to swing around the first end so that the first connecting hole 121 and the second connecting hole 331a are arranged opposite to each other. The fastener is used to pass through the first connecting hole 121 and the second connecting hole 331a in sequence and is detachably connected to the card block 12 so that the second end is fastened to the card block 12.

[0056] like Figures 6 to 8As shown, the shape of the locking block 12 in this embodiment of the present invention is adapted to the shape of the locking groove 311. One end of the locking groove 311 extends to the periphery of the mounting base 31. The locking groove 311 includes a first groove 311a and a second groove 311b connected sequentially from bottom to top along a first direction. The width of the first groove 311a is smaller than the width of the second groove 311b. With this configuration, after the locking block 12 enters the locking groove 311, it can only be disengaged from the through side of the locking groove 311, and cannot be disengaged from the opening of the first groove 311a, thereby helping to ensure the assembly stability of the mounting base 31.

[0057] like Figures 6 to 8 As shown, the telescopic device 10 of this embodiment further includes a rotating shaft 13, which is connected between the telescopic mechanism 11 and the mounting base 31, so that the mounting base 31 can be rotatably arranged around a first direction. This arrangement allows for adjustment of the installation angle of the photovoltaic power generation device 30 to adapt to different light angles.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
