[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate 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 may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" 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 various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1

[0035] Reference Figure 1-6 , which is the first embodiment of the present utility model, provides a cleaning mechanism, including a fixing component 100, which includes a fixing member 101, and a filter 103 arranged inside the fixing member 101;.

[0036] The cleaning component 200 includes a drive assembly 201 disposed above the filter 103, a rotating assembly 202 disposed below one side of the drive assembly 201, a transmission assembly 204 disposed below the other side of the drive assembly 201, a spoiler assembly 203 disposed at one end of the rotating assembly 202, a cutting assembly 205 disposed at one end of the transmission assembly 204, and a telescopic assembly 206 disposed below the cutting assembly 205, wherein the transmission assembly 204 and the rotating assembly 202 are connected via the drive assembly 201;

[0037] The filter screen 103 is fixed behind the water inlet by the fixing part 101 to prevent the aquatic plants in the water from being sucked into the inside of the device when absorbing water, thereby causing blockage, and the spoiler component 203 is fixed on one side of the fixing part 101. When it is necessary to pump water, the driving component 201 is operated in the forward direction to move the spoiler component 203, thereby disturbing the water flow in the fixing part 101, so that the aquatic plants in the water will not adhere to the inner wall of the fixing part 101. At this time, due to the design of the transmission component 204, the cutting component 205 does not move. When it is necessary to drain water, the driving component 201 operates in the reverse direction, and the spoiler component 203 is still in operation. Due to the design of the transmission component 204, the cutting component 205 starts to rotate, driving the telescopic component 206 to operate downward, thereby cutting the aquatic plants.

[0038] Furthermore, the fixing member 101 includes a fixing frame 101a, an extension pipe 101c disposed inside the fixing frame 101a, and a water inlet 101b disposed at the lower end of the extension pipe 101c; wherein the extension pipe 101c is fixedly connected to the fixing frame 101a.

[0039] Furthermore, the drive assembly 201 includes a drive motor 201a, a pulley 201b arranged below the drive motor 201a, a pulley 201c arranged on the fixed frame 101a, and a transmission belt 201d arranged between the pulley 1 201b and the pulley 2 201c, wherein the transmission belt 201d is wound around the outside of the pulley 1 201b and the pulley 2 201c, the output shaft of the drive motor 201a is fixedly connected to the pulley 1 201b, one end of the transmission belt 201d is sleeved on the outside of the pulley 1 201b, and the other end of the transmission belt 201d is sleeved on the outside of the pulley 2 201c, and the conventional ratio of the pulley 1 201b to the pulley 2 201c is greater than 1, which is used to accelerate the rotation speed of the transmission assembly 204.

[0040] Furthermore, the rotating assembly 202 includes a rotating shaft 202a provided below the pulley 1 201b, a transmission bevel gear 202b provided at one end of the rotating shaft 1 202a, a rotating shaft 2 203a provided on the inner wall of the fixed frame 101a, and a rotating bevel gear 202c provided on the outside of the rotating shaft 2 203a, wherein the transmission bevel gear 202b is engaged with the rotating bevel gear 202c, and the rotating shaft 1 202a is rotated by the driving assembly 201. Since the rotating shaft 1 202a is fixedly connected to the transmission bevel gear 202b, the transmission bevel gear 202b rotates, and the rotating shaft 2 203a is rotationally connected to the inner wall of the fixed frame 101a, and the rotating shaft 2 203a is fixedly connected to the rotating bevel gear 202c, so the rotating bevel gear 202c drives the spoiler assembly 203 to rotate, thereby disturbing the water flow.

[0041] Furthermore, the spoiler assembly 203 includes a spoiler fan 203b arranged at one end of the second rotating shaft 203a, a spoiler tube 203c arranged on one side of the extension tube 101c, and an isolation net 203d arranged at one end of the spoiler tube 203c; wherein, the spoiler fan 203b is arranged inside the spoiler tube 203c. Since the second rotating shaft 203a is fixedly connected to the spoiler fan 203b, the spoiler fan 203b will drive the flow rate in the water to become faster, and the upper end of the extension tube 101c pumps water, so the water flows upward, and the spoiler fan 203b makes the water flow toward the cutting assembly 205. From the force analysis, it can be seen that the water will drive aquatic plants and the like in the water into the cutting assembly 205.

[0042] Furthermore, the transmission assembly 204 includes a connecting shaft 204a provided below the pulley 201c, a connecting plate 204b provided on one side of the connecting shaft 205b, a connecting rod 204c provided at one end of the connecting plate 204b, a torsion spring 204e provided on the outside of the connecting rod 204c, and a pawl 204d provided at the lower end of the connecting rod 204c, one end of the torsion spring 204e is fixedly connected to the connecting plate 204b, the other end of the torsion spring 204e is fixedly connected to the pawl 204d, the pawl 204d is rotatably connected to the connecting rod 204c, and the torsion spring 204e is provided so that after the ratchet 205c hits the pawl 204d, the pawl 204d will rotate a certain angle and then reset.

[0043] Furthermore, the cutting assembly 205 includes a collecting box 205e provided on one side of the extension tube 101c, a connecting shaft 205b provided above the collecting box 205e, a fixed disk 205a provided at the upper end of the connecting shaft 205b, a ratchet 205c provided above the fixed disk 205a, and a cutting disc 205d provided at the lower end of the connecting shaft 205b; wherein the ratchet 205c is engaged with the pawl 204d, and when the driving motor 201a rotates forward, the transmission belt 201d drives the pulley 201c to rotate, and the pulley 201c drives the connecting plate 204b fixed thereto to rotate. The ratchet 205c and the pawl 204d are not matched, so the ratchet 205c will not rotate, so the fixed disk 205a fixedly connected to the ratchet 205c will not rotate, and the cutting disc 205d will not rotate. When the drive motor 201a is reversed, the ratchet 205c and the pawl 204d are matched, so the ratchet 205c will rotate, thereby driving the cutting disc 205d to rotate through the connecting shaft 205b. This design is to reduce the load of the drive motor 201a, thereby increasing the service life of the drive motor 201a.

[0044] Furthermore, the telescopic assembly 206 includes a telescopic motor 206a arranged inside the connecting shaft 205b, a telescopic rod 206b arranged at one end of the telescopic motor 206a, a fixed rod 206c arranged on one side of the telescopic rod 206b, and a baffle 206d arranged at one end of the fixed rod 206c. When the cutting disc 205d rotates, since the telescopic end of the telescopic rod 206b is threadedly connected to the collection frame, the telescopic rod 206b will move downward, driving the cutting disc 205d to rotate. At this time, the fixed rod 206c fixedly connected to the telescopic end of the telescopic rod 206b will drive the baffle 206d downward to block the water inlet, ensuring that the collection box 205e is completely cut.

[0045] Operation process: Start the driving motor 201a to rotate forward, thereby driving the pulley 1 201b to rotate forward, and the pulley 1 201b drives the transmission bevel gear 202b to rotate through the rotating shaft 1 202a, thereby driving the rotating bevel gear 202c to rotate, and thus the turbulence fan 203b is driven to rotate through the transmission of the rotating shaft 203a, thereby accelerating the flow rate of water and causing the water to flow towards the collection box 205e, and the transmission belt 201d drives the pulley 201c to rotate, and the pulley 201c drives the connecting plate 204b fixed to it to rotate, thereby driving the connecting rod 204c to do a circular motion, and at this time the ratchet 205c and the pawl 204d do not cooperate, so the cutting disc 205d does not rotate;

[0046] When the drive motor 201a is started to reverse, the rotating component 202 and the spoiler component 203 operate in the opposite direction, and the function remains unchanged. At this time, the pulley 201c drives the connecting plate 204b to rotate, driving the connecting rod 204c to perform reverse circular motion. At this time, the ratchet 205c cooperates with the pawl 204d, thereby driving the connecting shaft 205b to rotate, thereby rotating the cutting disc 205d. Since the telescopic end of the telescopic rod 206b is threadedly connected to the collection frame, the cutting disc 205d and the fixed rod 206c will move downward, thereby driving the baffle 206d to move downward. When the cutting is completed, the telescopic motor 206a will cause the telescopic rod 206b to rotate in the opposite direction, so that the cutting disc 205d returns to its original position.

[0047] Example 2

[0048] During use, since the knife is made of iron and there are acidic substances in the aquatic plants, it will corrode the knife.

[0049] Reference Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, it also includes a disassembly component 300, which includes a cavity 301 arranged on one side of the cutting disc 205d, a tool plate 302 arranged inside the cavity 301, and an expansion screw 303 arranged on one side of the tool plate 302.

[0050] The rest of the structure is the same as that of Example 1.

[0051] Operation process: When disassembly is required, the tool plate 302 is removed from the cutting disc 205d by rotating the expansion screw 303, and replaced with a new tool plate 302. The tool plate 302 is then fixed to the cutting disc 205d by tightening the expansion screw 303. Regular replacement in this way can avoid wear of the tool plate 302.

[0052] Example 3

[0053] The third embodiment of the present utility model is different from the previous embodiment in that: a hydropower station detection device includes a cleaning mechanism and a sampler 102, which is arranged inside a fixed frame 101a, and a power supply module 402 is arranged above the sampler 102, and the power supply module 402 is used to provide power for the drive motor 201a and the sampler 102; a control module 401 is arranged on the outside of the fixed frame 101a and fixedly connected to the fixed frame, and the control module 401 is used to make the drive motor 201a rotate forward or reverse; the sampler 102 adopts an s32-g type sampler, and the s32-g type sampler provides a cylinder sampling system purge in the sample, a purge sampling tube connection, and a quick connector to disconnect the sampling tube, which has the advantage of clearing the sample point to ensure that there is no sample residue or accumulation, ensuring that the representative and pollution-free optimal sample is sampled, and the unique design ensures the accuracy and safety of the sample.

[0054] Also includes the following modules:

[0055] The analysis module 403 is electrically connected to the power supply module 402. Both the analysis module 403 and the power supply module 402 are arranged above the sampler and positioned inside the fixed frame. The analysis module 403 is used to analyze the water extracted by the sampler.

[0056] The rest of the structure is the same as that of Example 1 or 2.
