Description

Technical Field

[0001] The utility model relates to the technical field of dry dock door maintenance auxiliary devices, in particular to an underwater mobile monitoring floating bar assembly for a dry dock door. Background Art

[0002] The floating and sinking installation of the dry dock door overhaul is a major operation node in the dock door overhaul. After the dry dock door lies down, it is invisible to human vision underwater, and its movement law and underwater posture cannot be judged by the shore operators. If you want to know the underwater situation of the dock door, such as lying depth, lying angle, floating and sinking dynamics, etc., you need to rely on divers to circle underwater to explore, measure and report, which is time-consuming and laborious. Especially when the dock door is in motion, there is a delay in the diver's reporting and monitoring. In addition, the safety risk of divers' underwater operations is high, and they cannot complete related operations, and cannot realize dynamic monitoring during the underwater dry dock door maintenance process.

[0005] The hollow tube is a PVC tube, sealed at both ends, and the U-shaped ring plays a role of connection and fixing. The U-shaped ring supports the hollow tube, and the pull rope is fixed to the bottom of the U-shaped ring. In the water, the hollow tube is in a vertical state. By installing four sets of monitoring floating bars of the utility model at appropriate positions at the four corners of the upper surface after the dock door lies down, the shore operator pulls or retracts the pull rope of the floating bar to keep the floating bar in a vertical floating state. The lying depth, lying angle, floating and sinking dynamics of the dock door can be clearly observed through the water gauge scale of the floating bar out of the water. It is a very practical monitoring floating bar for daily opening and closing, overhaul floating or installation of the dock door.

The sealing end caps are sleeved at both ends of the hollow tube and can be fixed by hot melting or clamping. After installation, a water test is performed to check if there is no leakage before use.

[0007] Preferably, the scale range of the water gauge is 0.1 to 1.5 m, and more preferably, the scale range of the water gauge is 0.1 to 1.2 m.

[0008] Furthermore, the underwater mobile monitoring floating bar assembly of the dry dock door of the utility model also includes a collar, one end of the hollow tube is embedded in the collar to achieve fixation; the collar is fixed to the U-shaped ring by spot welding. The collar is an iron ring, which is sleeved on the hollow tube, fixed to one end, and then the collar is fixed to the U-shaped ring by spot welding to achieve fixation of the entire hollow tube and the U-shaped ring.

[0010] In order to facilitate the installation and fixation of the underwater mobile monitoring float assembly of the dry dock door, the utility model also designs a permanent magnetic base. The rooting point of the monitoring float is measured and marked on the dock door, and then the permanent magnetic base with a fixing ring is sucked onto the predetermined point of the dock door; the monitoring float rope passes through the permanent magnetic base with a fixing ring and is pulled to the dock surface for standby use; the hollow tube is pulled to the dock surface and thrown into the water after the dock door enters the water.

[0011] Preferably, the permanent magnetic base weighs 30 to 50 kg.

[0012] Furthermore, the drawstring is a non-elastic drawstring.

[0013] Furthermore, the length of the hollow tube is 1.7 to 2.1 m, and the diameter is 100 to 120 mm.
