Description

Technical Field

[0001] The present application relates to the field of ship draft detection, and in particular to a ship draft detection device. Background Art

[0002] Ship draft detection is an important task related to ship navigation safety and effective transportation. It mainly refers to measuring the part of the ship hull immersed in water under different loading conditions, that is, the depth below the waterline. Accurate measurement of ship draft depth is of great significance to ensure that the ship does not touch the bottom of the water during navigation, does not violate the draft restrictions of the port, maintains good stability, and effectively controls the load;

[0003] The existing ship draft detection devices mainly include traditional mechanical detection devices and modern electronic detection devices. Compared with traditional mechanical detection devices, modern electronic detection devices have the characteristics of high precision and high automation, and are widely used in the detection of existing ship draft conditions.

[0004] However, modern electronic detection devices are highly dependent on the power system. If the power supply system or electronic equipment fails, the measurement function will be directly lost. Therefore, traditional mechanical detection devices can be installed on ships as a backup solution and used in conjunction with modern electronic detection devices to jointly detect the draft of ships.

[0005] The float measuring device is a common traditional mechanical detection device for ship draft. When in use, the float is installed under the hull by a chain or cable, and changes synchronously with the draft depth of the hull. When the ship is docked or no measurement is needed, the float and a part of the chain or cable connected to it remain above the water surface. Staying on the water surface for a long time will cause the float and some of the materials connected to it to age and become brittle, and it is easy to breed algae and other organisms to attach and grow, thereby affecting the service life of the float, and also affecting the measurement accuracy. In order to solve the above problems, a ship draft detection device is proposed.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0010] Preferably, the detection assembly includes a draft scale, a float plate, and a guide shaft, the draft scale and the float plate are both mounted on the guide shaft, the draft scale is located above the float plate, the float plate is slidably arranged inside the slide cylinder, and the bottom end of the draft scale is connected to a supporting folding assembly.

[0028] Reference Figure 1-4 The detection assembly includes a draft scale 10, a floating plate 11, and a guide shaft 16. The draft scale 10 and the floating plate 11 are both sleeved on the guide shaft 16. The draft scale 10 is located above the floating plate 11. The floating plate 11 is slidably arranged inside the slide cylinder 3. The bottom end of the draft scale 10 is connected to a supporting folding assembly;

At the same time, the support plate 4 can be made of stainless steel with a water filter hole, which is corrosion-resistant. The water filter hole can reduce the resistance of the slide tube 3 after entering the water. After entering the water, the bottom of the support plate 4 is flush with the bottom of the hull 101.

[0035] By adopting the above technical solution, the support plate 4 can support the slide cylinder 3. By rotating the turntable 8, the support plate 4 approaches the connecting plate 5 under the action of the threaded rod 7. The guide rod 6 provides a guide for the movement of the support plate 4. The limit block 9 limits the position of the support plate 4 on the guide rod 6 and the threaded rod 7. The limit block 9 can be fixed or threaded at the bottom of the guide rod 6 and the threaded rod 7.

[0036] Reference Figure 3 , 4, a water inlet 12 is provided at the bottom of the support plate 4 in a circumferential direction corresponding to the slide cylinder 3;

[0046] The implementation principle of a ship draft detection device in an embodiment of the present application is as follows: when in use, the shell 1 is fixed in a slot on the hull 101 through the clamping block 2, so that the support plate 4 supports the slide cylinder 3 to enter the water. After entering the water, the bottom of the support plate 4 is flush with the bottom of the hull 101, and water enters the slide cylinder 3 through the water inlet 12 at the bottom of the support plate 4. Under the action of the buoyancy of the water, the floating plate 11 floats upward along the guide shaft 16 inside the slide cylinder 3, and at the same time pushes the draft scale 10 to move upward, thereby realizing the draft condition detection of the hull 101. The staff can obtain the draft value of the ship 101 by observing the movement of the part of the draft scale 10 located above the shell 1. After use, the turntable 8 is rotated, and the support plate 4 approaches the connecting plate 5 under the action of the threaded rod 7, and the slide cylinder 3 is folded to a position slightly higher than or flush with the highest waterline 102.
