[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0029] Secondly, the term "one 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 term "in one embodiment" that appears in different places in 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.

[0030] Example 1, reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, provides an extension mechanism, including an extension component 100, the extension component 100 includes a movable cover 102, a protective cover 103 movably arranged outside the movable cover 102, and a positioning cover 104 movably arranged on the outer wall of the protective cover 103.

[0031] Preferably, the movable cover 102 is slidably connected to the protective cover 103 , the positioning cover is slidably connected to the protective cover 103 , and the movable cover 102 can slide along the axial direction of the protective cover 103 toward a side away from the positioning cover 104 .

[0032] A spiral groove 103 a is formed on the inner wall of the protective cover 103 . A driving cover 105 is movably provided on the inner wall of the protective cover 103 . The driving cover 105 is located between the movable cover 102 and the protective cover 103 .

[0033] Preferably, the thickness of the spiral groove 103a does not exceed the thickness of the protective cover 103, and the spiral groove 103a spirals upward from the bottom of the protective cover 103. The driving cover 105 is rotatably connected to the protective cover 103. The driving cover 105 can rotate between the protective cover 103 and the movable cover 102, and the driving cover 105 cannot slide along the axial direction of the protective cover 103.

[0034] The outer wall of the driving cover 105 is provided with a first limiting groove 105a, and the outer wall of the driving cover 105 is also provided with a limit groove 105b, and the limit groove 105b is connected to the first limiting groove 105a.

[0035] Preferably, the first limiting groove 105a is parallel to the axis of the protective cover 103, and the first limiting groove 105a runs through the entire driving cover 105. The first limiting groove 105a connects the protective cover 103 and the movable cover 102. The limit groove 105b is perpendicular to the first limiting groove 105a, and the limit groove 105b also runs through the driving cover 105 and is connected to the external movable cover 102 and the protective cover 103. The limit groove 105b is arranged along the circumference of the driving cover 105.

[0036] A support block 102a is disposed at the bottom end of the movable cover 102, and a limiting block 102b is fixedly disposed on the outer wall of the support block 102a. The limiting block 102b is movably matched with the spiral groove 103a and the first limiting groove 105a.

[0037] Preferably, there are two limit blocks 102b arrayed, and the limit blocks 102b can slide along the spiral groove 103a and the first limit groove 105a. The limit blocks 102b and the limit groove 105b are movably matched. When the limit block 102b slides along the first limit groove 105a to its top, the limit block 102b naturally slides into the limit groove 105b. At this time, the limit block 102b can no longer slide along the spiral groove 103a and the first limit groove 105a.

[0038] A connecting block 105c is fixedly provided at the bottom end of the driving cover 105, a rotating handle 105d is fixedly provided at the bottom end of the connecting block 105c, and a positioning groove 105e is provided at the bottom end of the connecting block 105c.

[0039] Preferably, a plurality of positioning grooves 105e are arranged in a circular array at the bottom of the connecting block 105e.

[0041] Preferably, a circular array of positioning blocks 104a is arranged inside the positioning cover, and the number of positioning blocks 104a is greater than or equal to 2. When the positioning cover 104 is slid toward the bottom of the protective cover 103 along the axial direction of the protective cover 103, the positioning blocks 104a disengage from the positioning groove 105e. At this time, rotating the handle 105d can make the movable cover 102 slide along the spiral groove 103a to extend the flashlight.

[0042] In summary, when in use, it is preferred to slide the positioning cover 104 to the bottom of the protective cover 103. When the positioning cover 104 is positioned, the positioning block 104a disengages from the positioning groove 105e. At this time, the handle 105d can be rotated, so that the support block 102a drives the movable cover 102 to slide and rise along the spiral groove 103a and the first limit groove 105a, and slide along the axial direction of the protective cover 103 away from the handle 105d to extend the length of the flashlight. When the movable cover 102 is extended to a suitable length, the positioning cover 104 is released. Under the action of the spring 106, the positioning cover 104 automatically rebounds, so that the positioning block 104a enters the positioning groove 105e, and the handle 105d cannot be rotated. Even if the movable cover 102 is extended to a certain length, it is convenient for the inspection personnel of the hydropower station to conduct subsequent inspections of the equipment.

A through hole 203 b is formed on the end surface of the support block 102 a . The through hole 203 b connects the movable cover 102 and the driving cover 105 .

[0053] Preferably, the wiring harness of the display 203 enters the interior of the flashlight through the wiring reel 203a and is electrically connected to the internal power supply of the flashlight. The power cord of the battery is wound around the outer wall of the winding post 206a through the through hole 203b. When the movable cover 102 moves, the wiring harness stretches. When the movable cover 102 retracts, the wiring harness is automatically wound around the outer wall of the winding post 206a through the action of the torsion spring 206b.

[0054] In summary, the staff chooses whether to move the movable cover 102 according to the current equipment. After confirming the appropriate length of the flashlight according to the above operation, the equipment is photographed through the camera 201, and the image is displayed on the display 203. The processor 204 stores the data in advance and compares it with the current image data to determine what state the equipment is in at this time. At the same time, the inspection personnel can also make judgments based on the image, and the image data is uploaded to other staff members through the wireless communicator 205. The equipment status is confirmed through the above triple judgment, which not only simplifies the work intensity of the inspection personnel, but also ensures the normal operation of the hydropower station equipment according to the triple judgment, and prevents equipment damage caused by misjudgment by one of the inspection personnel or others.
