Description

Technical Field

[0001] This utility model belongs to the field of sensor monitoring technology, specifically relating to a monitoring device for the miter gate and anti-arc gate of a high-head ship lock. Background Technology

[0002] Ship lock miter gates operate under low-speed, heavy-load conditions for extended periods. During the opening and closing of the lock, they are subjected to swells, dynamic water loads, water flow impacts, and the influence of microorganisms and floating debris in the water, causing frequent vibrations and small vertical displacements of the gate body. This results in irreversible damage to the miter gate. When the structural damage accumulates to a certain extent, it can lead to serious consequences such as the breakage of the AB rod / back tie rod and cracks appearing in the deep-water area of ​​the gate body. This not only affects navigation but also causes serious social impacts and economic losses.

[0003] To ensure the structural safety of the lock, existing detection methods deploy sensors at all locations on the miter gates most prone to safety hazards, enabling real-time online dynamic monitoring of the gates' health status and effectively eliminating potential safety risks.

[0004] However, in the current market, electronic sensors are mainly installed by adding a bottom with mounting holes, and then using screws to install and fix the electronic sensor in the mounting holes. This traditional installation method is inconvenient because it requires external tools to disassemble the electronic sensor when it needs to be replaced, and disassembling and then reinstalling it can easily affect the stability of the installation.

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please see Figure 1-4This utility model provides the following technical solution: a monitoring device for the miter gate and anti-arc gate of a high-head ship lock, including a fixed mounting base 1 and a sensor 5, and a waterproof shell 2. The sensor 5 is installed inside the waterproof shell 2. The waterproof shell 2 is slidably mounted inside the protective shell 11 on the fixed mounting base 1 via a limiting slide groove 21. Mounting plates 22 are provided on both sides of the waterproof shell 2. Disassembly and assembly components that are locked to the mounting plates 22 are provided on the inner walls of both sides of the protective shell 11. The disassembly and assembly components include a transmission structure 3 and a locking structure. The waterproof shell 2 ensures that the sensor 5 works in a dry environment. The waterproof shell 2 slides into the protective shell 11 along the limiting slide table 13 via the limiting slide groove 21. The protective shell 11 is used to reduce and buffer external impact forces. The transmission structure 3 drives the locking structure to realize the quick disassembly and assembly of the waterproof shell 2 and the sensor 5, which facilitates the installation and disassembly of the sensor.

[0028] Specifically, the transmission structure 3 includes a bidirectional lead screw 31, which is installed in a groove on the inner wall of the protective housing 11. The top of the bidirectional lead screw 31 extends out of the protective housing 11 and is connected to a handle 32. The upper and lower ends of the bidirectional lead screw 31 are connected to a locking structure via a lead screw slider. By rotating the bidirectional lead screw 31 with the handle 32, the upper and lower locking plates 4 move in opposite directions via the lead screw slider. The locking plates 4 drive the locking rod 41 to insert into the locking hole 24 on the mounting plate 22, thereby fixing the waterproof housing 2 and the sensor 5 inside the protective housing 11. When disassembling, it is only necessary to rotate the handle in the opposite direction, which makes it easy to disassemble the sensor 5 directly without the aid of external tools, greatly facilitating the installation and use of the sensor 5.

[0029] Specifically, the locking structure includes a locking plate 4, on which a locking rod 41 is provided, and the locking rod 41 cooperates with the locking hole 24 on the mounting plate 22 to lock and connect.

[0030] Specifically, a moisture-proof and dehumidifying plate 26 is fastened to the inner wall of the waterproof shell 2 via a snap-fit ​​seat 25, and moisture-absorbing activated carbon 27 is provided on the moisture-proof and dehumidifying plate 26; a lens plate 23 is provided on the waterproof shell 2, and the moisture inside the waterproof shell 2 will be absorbed by the moisture-proof and dehumidifying plate 26 and the moisture-absorbing activated carbon 27. The moisture-absorbing activated carbon 27 has a fine porous structure, which can adsorb the moisture contained in the air in order to achieve the final dehumidification effect; ensuring that the sensor 5 works in a dry environment, thereby ensuring its waterproof effect.

[0031] Specifically, the waterproof shell 2 has a limiting groove 21 at the bottom and top, and the protective shell 11 has a limiting slide 13 at the top and bottom that is compatible with the limiting groove 21.

[0032] Specifically, the fixed mounting base 1 is provided with fixing holes 12, and the fixed mounting base 1 is fixed to each monitoring position of the miter gate and the anti-arc gate of the high head ship lock by bolts; the fixed mounting base 1 does not need to be repeatedly disassembled and reassembled, only the sensor 5 needs to be installed and removed.

[0033] The working principle and usage process of this utility model are as follows: When using this utility model, the operator fixes the mounting base 1 to the monitoring positions of the high-head ship lock's miter gate and anti-arc gate using bolts. When installing the electronic sensor 5, simply insert the sensor 5 into the waterproof shell 2. The waterproof shell 2 is then slid into the protective shell 11 through the bottom and top limiting grooves 21 along the limiting slide table 13. The protective shell 11 is used to reduce and buffer external impact forces. Then, the handle 32 is used to rotate the bidirectional lead screw 31, which, through the lead screw slider, drives the upper and lower locking plates 4 to move towards each other. The locking plates 4 drive the locking rod 41 to insert into the locking hole 24 on the mounting plate 22. The waterproof housing 2 and sensor 5 can be fixed inside the protective housing 11. During disassembly, simply rotate the handle 32 in the opposite direction to drive the bidirectional lead screw 31 to rotate, thereby causing the locking plate 4 to move in the opposite direction, thus releasing the waterproof housing 2. This allows the sensor 5 to be easily disassembled without the aid of external tools, greatly facilitating the installation and use of the sensor 5. The moisture inside the waterproof housing 2 will be absorbed by the moisture-proof dehumidifying plate 26 and the moisture-absorbing activated carbon 27. The moisture-absorbing activated carbon 27 has a fine porous structure that can absorb the moisture contained in the air to achieve the final dehumidification effect. This ensures that the sensor 5 operates in a dry environment, thereby ensuring its waterproof effect.
