Description

Technical Field

[0001] The invention relates to the technical field of cable detection, in particular to a cable detection device for a hydropower plant. Background Art

[0002] Cables are an important part of hydropower plants, as they will be responsible for transmitting huge amounts of electrical energy from underwater turbines to ground-based substations. Due to the particularity of the underwater environment, these cables must have extremely high water pressure resistance and mechanical strength, while also being able to resist possible chemical corrosion and biological adhesion. Before laying, it is crucial to ensure that there are no protrusions or damage on the cable surface, as these defects may deteriorate rapidly in high pressure and underwater environments, leading to insulation failure or other serious operational failures.

[0003] However, the task of checking the cable surface for protrusions usually requires engineers to conduct long manual visual inspections. They must carefully look along the length of the cable, looking for any possible anomalies. Although this inspection method is meticulous, it is extremely time-consuming and prone to visual fatigue for inspectors. Long periods of focused observation not only put pressure on the eyes, but can also cause distraction, increasing the risk of missed inspections. In addition, manual inspections are also limited by the inspector's experience level and work status on the day, which may affect the accuracy and reliability of the inspection results.

DETAILED DESCRIPTION

[0028] 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 in conjunction with the accompanying drawings.

[0029] 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.

[0030] 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.

[0031] Example 1, reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a cable detection device for a hydropower plant. The cable is inserted from the support component 200, and each rotating rod 301 will support the wire inspection wheel 302a to contact the cable. When there is a protrusion on the cable surface, the marking sponge 401 in the marking component 400 will be displaced to mark the vicinity of the protruding part of the cable, thereby realizing the detection of the cable, so that the staff can carry out subsequent processing, effectively solving the problems brought about by the prior art.

[0032] Specifically, the bearing assembly 100 includes a fixed cylinder 101 and a top ring 102 integrally formed on the end surface of the fixed cylinder 101; wherein, the fixed cylinder 101 and the top ring 102 are of an integrated design. During actual use, the fixed cylinder 101 can be fixed by a bracket, and the cables entering and exiting the fixed cylinder 101 need to remain horizontal and coaxial with the fixed cylinder 101.

[0033] The support assembly 200 includes a bottom ring 201 rotatably disposed on the end surface of the top ring 102; the bottom ring 201 can rotate, but cannot move. It should be noted that an elastic member is also disposed at the connection between the bottom ring 201 and the top ring 102, that is, when the bottom ring 201 rotates, it can have a certain reset effect under the action of the elastic member.

[0034] The line inspection assembly 300 includes a rotating rod 301 movably connected to the end face of the top ring 102 through a rotating shaft, a mounting frame 302 arranged on the end face of the rotating rod 301, and a line inspection wheel 302a arranged outside the mounting frame 302; wherein, in this embodiment, the number of the rotating rods 301 is 4, and each rotating rod 301 is provided with a line inspection wheel 302a.

[0035] The marking assembly 400 includes a marking sponge 401 movably disposed in the fixed cylinder 101 . The number of the marking sponges 401 in this embodiment is also 4, and the 4 marking sponges 401 will move synchronously.

[0036] In summary, when the cable passes between the inspection wheels 302a and enters the fixed tube 101, if there is a protrusion on the outer wall of the cable, the protrusion will push the inspection wheels 302a to move relative to each other and move away from each other, thereby driving the rotating rod 301 to rotate. The rotation of the rotating rod 301 will indirectly drive the marking sponge 401 to move to mark the cable surface.

[0037] Example 2, reference Figures 1 to 10 , which is the second embodiment of the present invention, is different from the previous embodiment in that a method is provided in which the rotation of a rotating rod 301 is used to drive the line checking wheel 302a to move.

[0038] Specifically, the support assembly 200 further includes a plurality of support columns 203 connected to the bottom ring 201 by bolts and distributed in a circumferential array, and a cover plate 202 is provided at one end of the support column 203 away from the bottom ring 201, and a mounting channel 201a is formed between the cover plate 202 and the bottom ring 201 due to the arrangement of the support columns 203. Among them, due to the arrangement of the support columns 203, the rotation between the cover plate 202 and the bottom ring 201 is synchronous.

[0039] One end of the rotating rod 301 is connected to the mounting frame 302 by passing through the mounting channel 201a. The outer wall of the rotating rod 301 is movably sleeved with a transmission frame 301a, and the outer wall of the transmission frame 301a is connected to the cover plate 202 and the bottom ring 201 through a rotating shaft on both sides. Fig. 9 It can be seen that the transmission frame 301a is connected with the cover plate 202 and the bottom ring 201. Through the matching relationship between the transmission frame 301a, the cover plate 202 and the bottom ring 201, it is achieved that when the rotating rod 301 is deflected, the transmission frame 301a will drive the supporting assembly 200 to rotate as a whole.

[0040] The bearing assembly 100 further includes a connecting ring 103a movably sleeved outside the fixing tube 101, and a transmission slide groove 103a-1 is provided on the inner wall of the connecting ring 103a; a connecting channel 102a is provided through the end surface of the top ring 102, a fixing block 103b is screwed to the end surface of the connecting ring 103a, and the end surface of the fixing block 103b is connected to the bottom ring 201 by passing through the connecting channel 102a. The connecting ring 103a will rotate synchronously with the supporting assembly 200.

[0041] The bearing assembly 100 further includes a transmission member 104, and the transmission member 104 includes a slip ring 104a that is displaced on the outer wall of the fixing tube 101. The transmission member 104 is used to convert the rotational motion of the connecting ring 103 into a linear displacement.

[0042] The end surface of the slip ring 104a is provided with a bearing 104b, and a rotating ring 104c is rotatably provided in the bearing 104b, and a transmission slider 104c-1 is provided on the outer wall of the rotating ring 104c to slide with the transmission slide groove 103a-1, and a conflict groove 104a-1 is provided on the inner wall of the slip ring 104a. The bearing 104b is provided so that the rotating ring 104c will not cause the rotation of the slip ring 104a during its rotation, and will not conflict with the displacement of the slip ring 104a.

[0043] In combination with the above description, when the cable passes through the axis of the support assembly 200, it will also pass through each wire inspection wheel 302a. The size of the cable to be tested may not be restricted, that is, the outer wall of the cable may contact with the wire inspection wheel 302a, or may not contact with it.

[0044] When there is no protrusion on the cable surface, the cable will pass through the fixing tube 101 smoothly, and the wire inspection wheel 302a will also support the cable to pass through. Once there is a protrusion on the cable surface, the protrusion area will give a certain force to the wire inspection wheel 302a, so that each wire inspection wheel 302a moves away from each other. The deflection of the wire inspection wheel 302a will cooperate with the installation channel 201a through the transmission frame 301a sliding on its outer wall, so that the support assembly 200 rotates as a whole.

[0045] The rotation of the supporting component 200 will transmit the rotation to the connecting member 103 through the fixed block 103b, and through the cooperation of the transmission slide groove 103a-1 and the transmission slider 104c-1, the swivel 104c will not only rotate, but also push the slip ring 104a to move, and the displacement of the slip ring 104a will squeeze the marking component 400 whose end protrudes outside the fixed tube 101, and the marking work near the protruding part of the cable is completed through the contact between the marking sponge 401 and the cable surface.

[0046] Example 3, reference Figures 3 to 10 , which is the third embodiment of the present invention. Different from the previous embodiment, the movement mode of the marking assembly 400 driven by the slip ring 104a is further optimized.

[0047] Specifically, the marking assembly 400 further includes a feed column 402 connected to the marking sponge 401, and a feed through hole 402a is provided outside the feed column 402, and a movable column 403 is provided on the end surface of the feed column 402, and the end surface of the movable column 403 extends outside the fixed cylinder 101 and is provided with a trigger end 403a. The trigger end 403a is an inclined surface.

[0048] A paint storage ring 101a is provided in the fixed cylinder 101, and a paint outlet channel 101a-1 is provided through the inner wall of the paint storage ring 101a to slide with the feed column 402. The paint storage ring 101a is hollow and contains paint that can be used for marking, and the color can be white. Under normal circumstances, when the cable passes smoothly, the marking component 400 does not work, but in order to avoid the marking sponge 401 being out of paint, the paint will enter the feed through hole 402a through the paint outlet channel 101a-1 to wet the marking sponge 401.

[0049] A handle 101b is provided on the outer wall of the fixed cylinder 101. The handle 101b is used to facilitate the staff to control the entire device.

[0050] The inner wall of the slip ring 104a is provided with a connecting slider 104a-2, and the outer wall of the fixed cylinder 101 is provided with a connecting slot 101c that is slidably matched with the connecting slider 104a-2. The matching of the connecting slider 104a-2 and the connecting slot 101c can restrict the movement of the slip ring 104a, and only displacement movement occurs.
