[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0025] The utility model embodiment discloses a device for monitoring the water level in a cable channel.
[0026] Reference Figure 1-4 A water level monitoring device in a cable channel includes a mounting plate 1 and a connecting plate 8. Bolts 2 are threadedly sleeved inside both ends of the mounting plate 1. The surfaces of the two bolts 2 are coated with anti-rust paint to improve the anti-rust performance of the bolts 2. The connecting plates 8 are arranged on one side of the mounting plate 1. A wedge-shaped groove is provided on the side wall of the mounting plate 1. A wedge-shaped block 10 is clamped on the inner side of the wedge-shaped groove. One side of the wedge block 10 is fixedly connected to the connecting plate 8. A plurality of water level monitoring alarms 3 are fixedly arranged on the side of the connecting plate 8 away from the mounting plate 1 from top to bottom. A plurality of water level monitoring alarms 3 are provided on the surface of the connecting plate 8 away from the mounting plate 1. The alarm mounting hole facilitates the installation of the water level monitoring alarm 3 at different heights. A toggle switch 13 is provided on one side of the multiple water level monitoring alarms 3. A side panel 4 is fixedly provided at the lower end of the connecting plate 8 and on the side close to the water level monitoring alarm 3. A through hole is provided on the surface of the side panel 4. A sliding rod 5 is provided in the internal movable sleeve of the through hole. The cross-sections of the sliding rod 5 and the through hole are both rectangular, so that the sliding rod 5 cannot rotate, that is, it can slide stably. A floating plate 6 is fixedly provided at the lower end of the sliding rod 5, and a push plate 7 is provided below the lower toggle switch 13, and the push plate 7 is fixedly connected to the upper end of the sliding rod 5.
[0027] Reference Figure 1-4 A cavity is opened in the middle of the connecting plate 8, and a limiting mechanism for limiting the movement of the wedge block 10 is arranged inside and on both sides of the cavity. The limiting mechanism includes a rotating rod 9 and a blocking bar 11. The rotating rod 9 is rotatably arranged inside the cavity, and both ends of the rotating rod 9 extend to the outside of the cavity. Two blocking bars 11 are fixedly arranged at both ends of the rotating rod 9, and the side of the two blocking bars 11 close to the connecting plate 8 is in conflict with one side of the corresponding wedge block 10.
[0028] Reference Figure 1-4A torsion spring 12 is provided on the middle movable sleeve of the rotating rod 9, one end of the torsion spring 12 is fixedly connected to the rotating rod 9, and the other end of the torsion spring 12 is fixedly connected to the inner wall of the cavity. In a natural state, the elastic force of the torsion spring 12 will cause the rotating rod 9 to drive the blocking bar 11 to rotate and block the outside of the wedge block 10.
[0029] In the utility model, during use, when water accumulates in the underground cable tunnel, the water will push the floating plate 6 to move upward, and the floating plate 6 will push the push plate 7 to move upward via the slide bar 5. When the water level reaches a certain height, the push plate 7 will push the corresponding toggle switch 13 of the water level monitoring alarm 3, which can promptly alarm and conveniently notify the workstation personnel to perform drainage work. When the water level monitoring alarm 3 needs to be maintained and repaired, the rotating rod 9 is rotated to rotate the baffle bars 11 on both sides to separate from the wedge block 10, thereby releasing the limit on the wedge block 10 and pulling the wedge block 10 forward from the wedge groove, thereby realizing the disassembly of the connecting plate 8, which is convenient for disassembling the water level monitoring alarm 3 for maintenance and repair.
[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
