Channel inspection: regularly inspect the operation status of the channel, find defects that may cause channel failure or damage, and perform repairs and maintenance in a timely manner; 2. Dredging and maintenance; 3. Anti-corrosion and anti-fouling; 4. Inspection and maintenance; 5. Scheduled maintenance, etc.

[0003] Existing channels are generally equipped with protective nets, which are high and inconvenient to enter. Inspections of the channels require a long detour to reach the inner side of the channel. If a telescopic ladder is used to cross the protective net, due to the slope in the channel, the middle hinge angle of the general telescopic ladder is unstable and easily changes under the action of external pressure, thereby affecting the stability of the support. In addition, the ladder foot is not stable. Utility Model Content

A connecting rod 5 is connected to the connecting tube 4, and the connecting tube 4 is connected to the telescopic ladder 1 through the connecting rod 5. Figure 3 、 Figure 4 Figure 5 and Figure 6 The hinge is provided with a positioning assembly that can position the hinge angle of the telescopic ladder 1, and the positioning assembly includes a driving column 6 that is slidably connected to the connecting cylinder 4 respectively, and the driving column 6 is connected with a slider 14, and the inner wall of the connecting cylinder 4 is connected with a slide groove 15, and the slide groove 15 slides with the slider 14, and a spring 7 is connected relative to the driving column 6. The inner cylinder 3 is circumferentially connected with a plurality of through holes 8, and a positioning bead 9 is provided in the through hole 8. The hinge cylinder 2 is relatively connected with a plurality of limit grooves 10 in the circumferential direction, and the connecting cylinder 4 is connected with a driving assembly that can drive the driving column 6 to slide relatively. The driving assembly includes a spiral groove 11 connected to the driving column 6 circumferentially, and the connecting cylinder 4 is circumferentially connected with a through groove 12 arranged perpendicular to the axis of the connecting cylinder 4. A driving rod 13 is slidably connected relative to the spiral groove 11, and the driving rod 13 passes through the through groove 12 and extends out of the connecting cylinder 4.

[0027] The arrangement of the telescopic ladder 1, the articulated tube 2, the hinged member, and the positioning assembly in the above structure facilitates adjustment of the hinge angle between the two telescopic ladders 1 through the hinge connection between the articulated tube 2 and the hinged member, and the positioning assembly facilitates limiting the hinge angle between the telescopic ladders 1 to form a fixed triangular support structure, thereby preventing the angle of the telescopic ladder 1 from changing under the action of external pressure, thereby affecting the stability of the telescopic ladder 1, and the telescopic adjustment property of the telescopic ladder 1 itself facilitates telescopic adjustment according to needs.

[0028] Example 2

[0029] On the basis of embodiment 1, combined with the attached Figure 7 The free ends of the telescopic ladder 1 are respectively hinged with a stabilizing assembly, and the stabilizing assembly includes a connecting plate 16 on the outer side of the bottom end of the hinged telescopic ladder 1, and a plurality of anti-slip protrusions 17 are connected to the bottom end of the connecting plate 16.

[0030] The provision of the stabilizing assembly in the above structure facilitates strengthening the contact area between the free end of the telescopic ladder 1 and the foundation and enhancing friction, thereby further assisting in improving the stability of the telescopic ladder 1 .

[0031] The specific usage is as follows:

[0032] First, by pulling the driving rod 13 and rotating it in the direction of the through groove 12 in the direction of the axis of the connecting tube 4, the driving rod 13 drives the driving column 6 to slide relatively inward along the sliding groove 15 by sliding with the spiral groove 11. At this time, the spring 7 is compressed and stores force until the positioning bead 9 is no longer lifted by the driving column 6, and the articulation tube 2 and the inner tube 3 can be freely articulated and adjusted; after adjusting to a suitable angle, the driving rod 13 is released, and under the reset action of the spring 7, the driving column 6 slides relatively outward, thereby lifting the positioning bead 9, so that the positioning bead 9 passes through the through hole 8 and cooperates with the limiting groove 10 to limit the articulation tube 2. At this time, the articulation angle between the articulation tube 2 and the inner tube 3 is positioned and cannot be adjusted;

[0033] Then, by adjusting the length of the telescopic ladders 1 on both sides, the hinged part of the telescopic ladders 1 is made to cross the protective net. At this time, the telescopic ladders 1 form a stable triangular structure, which makes it convenient to enter the inner side of the river channel for observation through the telescopic ladders 1;

[0034] The coordinated arrangement of the connecting plate 16 and the anti-slip protrusions 17 facilitates increasing the contact area and friction between the connecting plate 16 and the foundation, further assisting in improving the stability of the telescopic ladder 1 .
