Description

Technical Field

[0001] This utility model relates to the field of shipbuilding, specifically a temporary protective device for the probes of depth sounders and logs. Background Technology

[0002] During shipbuilding, it is often necessary to install depth sounders and logs on the hull for subsequent depth and distance measurement after the ship is launched. For example... Figure 5 As shown, the main measuring component of a depth sounder or log is the transducer, which, as the sensing end, needs to extend to the outside of the hull to contact the seawater. Since it is installed during the hull construction process, the transducer of the depth sounder or log needs to be protected so that it is not damaged during hull grinding, welding, and painting.

[0003] In existing technologies, when depth sounders or logs are not in use, their probes (transducers) are typically temporarily protected with masking tape and aluminum foil tape, which are then removed when needed for deployment. However, in shipbuilding practice, this method is wasteful due to the reusability of masking tape and aluminum foil tape, and currently, there is no dedicated protective device to address this issue. Therefore, we propose a probe protection device for depth sounders or logs to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a temporary protection device for the probes of depth sounders and logs. This temporary probe protection device provides temporary protection for the transducers on depth sounders or logs, offering temporary protection during shipbuilding processes such as grinding, welding, and painting, preventing damage during these processes. Furthermore, it can be reused on different vessels.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A temporary protective device for depth sounder and log probe includes a housing. The bottom of the housing is provided with a suction cup pusher that penetrates and extends into the housing. A suction cup is installed at one end of the suction cup pusher inside the housing. A cavity air pressure pusher is connected to the outer ring of the suction cup. Grooves are provided on both sides of the bottom inner wall of the housing, and telescopic connecting rods are provided in the grooves. The lower part of the cavity air pressure pusher near the center of the housing is connected to the telescopic connecting rod through a movable connector.

[0007] As a preferred embodiment of this utility model, the suction cup has an internal cavity and is made of rubber.

[0008] As a preferred embodiment of this utility model, the bottom of the suction cup pusher is connected to the edge of the outer shell by a protective sleeve, and the protective sleeve is made of leather.

[0009] As a preferred technical solution of this utility model, the outer shell is made of aluminum, ensuring that its size covers the transducer surface of the depth sounder body or the logger body, and that the internal cavity is airtight.

[0010] As a preferred technical solution of this utility model, the movable connector adopts a hinged method, which allows the cavity air pressure pusher to move with the suction cup pusher.

[0011] As a preferred technical solution of this utility model, the end of the telescopic connecting rod away from the cavity pneumatic pusher is connected to the inner wall of the groove opened on the bottom inner wall of the outer shell, and the cavity pneumatic pusher is located in the groove opened on the bottom inner wall of the outer shell.

[0012] Compared with the prior art, this utility model provides a temporary protection device for the probes of depth sounders and logs, which has the following beneficial effects:

[0013] This utility model's temporary protection device for the depth sounder and log probe utilizes the principle of pneumatic vacuum. A protective cover prevents damage to the transducers of the depth sounder and log probe during operations such as painting, grinding, and welding. Its prominent location alerts workshop personnel to monitor the quality management of the depth sounder and log. The device can be retrieved before launching, thus protecting the depth sounder and log and enabling them to perform their navigation measurement functions smoothly. It also allows for efficient installation of the protection device, facilitating the installation and protection of depth sounders or logs on subsequent vessels, and is reusable.

A suction cup pusher 7 is provided at the bottom of the shell 1, extending through and into the interior of the shell 1. The suction cup 6 is installed at one end of the suction cup pusher 7 inside the shell 1, which can adsorb the transducer surface of the depth sounder body or the log body 9. A cavity air pressure pusher 2 is connected to the outer ring of the suction cup 6. Grooves are provided on both sides of the bottom inner wall of the shell 1, and telescopic connecting rods 4 are provided in the grooves. The lower part of the cavity air pressure pusher 2 near the center of the shell 1 is connected to the telescopic connecting rod 4 through a movable connector 3. When the cavity air pressure pusher 2 moves, a negative pressure is formed between the cavity air pressure pusher 2 and the shell 1, which provides a close fit and protection to the edge of the depth sounder body or the log body 9.

[0022] In this embodiment, a cavity 8 is formed inside the suction cup 6, and the suction cup 6 is made of rubber material, which facilitates the adsorption of the depth sounder body or the speedometer body 9. The bottom of the suction cup pusher 7 is connected to the edge of the outer shell 1 through a protective sleeve 5, and the protective sleeve 5 is made of leather, which can block external contaminants such as paint splashes.

[0023] The aforementioned outer shell 1 is made of aluminum, ensuring that its size covers the transducer surface of the depth sounder body or the speedometer body 9. The internal cavity 8 is airtight, and the movable connector 3 is hinged, allowing the cavity air pressure pusher 2 to move with the suction cup pusher 7. The end of the telescopic connecting rod 4 away from the cavity air pressure pusher 2 is connected to the inner wall of the groove opened in the bottom inner wall of the outer shell 1, and the cavity air pressure pusher 2 is located in the groove opened in the bottom inner wall of the outer shell 1, which facilitates the movement of the telescopic connecting rod 4.
