Description

Technical Field

[0001] The utility model relates to the technical field of speed log cables, in particular to a safety protection mechanism for ship speed log cables. Background Art

[0002] In modern ship operations, a speedometer is a navigation device that measures the ship's speed and accumulates the distance traveled. At present, marine speedometers mainly use electromagnetic speedometers or Kepler speedometers. During the application of the speedometer, the transducer needs to be installed on the ship's seabed valve to cooperate with the transceiver unit and the control unit to complete the speedometer work. At present, the transducer mainly relies on lines to transmit data during the installation process. However, during navigation at sea, the ship is bumpy due to the influence of sea breeze. The transceiver line of the transducer is in oblique contact with the edge of the guide cover of the seabed valve. When the ship is bumpy and shaking, the transceiver line is in contact with the slope and is prone to wear. In view of this, an in-depth study was conducted on the above-mentioned problem, which led to the creation of this case. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides an implementation scheme: when modern ships accumulate mileage, the speed meter is mainly used. The transducer of the speed meter is installed in the bottom valve of the ship. The transducer is connected to the transceiver through a cable. The application designs a cable safety protection mechanism for a ship speed meter, which is used to install the transducer of the speed meter and protect the cable. Specifically, it includes a seabed valve 1, in which a speed meter transducer 2 is arranged. The seabed valve 1 is the installation position of the speed meter transducer 2. The speed meter transducer 2 is fixed in the seabed valve 1. A transmission cable 3 is arranged at the center of the speed meter transducer 2. A fixed shell 4 is installed on the seabed valve 1. The fixed shell 4 is connected to the top of the seabed valve 1. The fixed shell 4 is used to block the top of the seabed valve 1 and is used to pass through the installation cable. A floating cable threader 5 is arranged on the fixed shell 4 to install the transmission cable.

[0020] According to the instruction manual Figure 1-3 It can be known that the floating cable threader 5 comprises a central groove 52, a connecting seat 51 is provided on the top of the fixed shell 4, the central groove 52 is a semi-spherical through groove with a missing arc, a buckle cover 53 is threadedly connected to the connecting seat 51, a through groove 54 is provided on the buckle cover 53 corresponding to the central groove 52, a central groove 52 is provided at the center of the connecting seat 51, the central groove 52 on the connecting seat 51 and the through groove 54 on the buckle cover 53 are buckled into a semi-spherical through groove with a missing arc, when installing, the buckle cover 53 is threadedly connected to the connecting seat 51 so that the through groove 54 is buckled with the connecting block 55, and when disassembling, the buckle cover 53 is reversely rotated from the connecting seat 51 to disengage the threaded connection;

[0021] The connection block 55 is a spherical block with a missing arc. The center groove 52, the through groove 54 and the connection block 55 are transitionally matched. The center groove 52 and the through groove 54 are buckled on the upper and lower sides of the connection block 55. A fixed sleeve 56 extends from the connection block 55. The fixed sleeve 56 is a tubular body with a partial conical structure. A limit ring 57 is arranged on the top of the fixed sleeve 56. The transmission cable 3 passes through the fixed sleeve 56 and the connection block 55. When encountering bumps, since the center groove 52 and the through groove 54 adopt a wrapped structure and are spherically connected, the elasticity of the transmission cable 3 can be used to achieve universal rotation. On the one hand, the direction can be adjusted at will when connecting the cable. On the other hand, the cable bending caused by bumps is buffered. At the same time, a wire threading protection groove 58 with a partial conical structure is opened on the connection block 55, and the wire threading protection groove 58 is connected to the inner cavity of the fixed sleeve 56 to prevent the cable from touching the folded edge of the wire threading protection groove 58 when bending.

[0022] As a preferred solution, further, the diameter of one end of the threading protection groove 58 communicating with the inner cavity of the fixing sleeve 56 is smaller than the inner diameter of the end facing the inner cavity of the seabed valve 1 , ensuring that the cable will not touch the bottom edge of the connection block 55 .

[0023] As a preferred solution, further, the central groove 52 and the through groove 54 are buckled into a spherical groove with arcs at both ends, which can wrap the limiting connection block 55 without affecting the rotation of the connection block 55.

[0024] As a preferred solution, further, the fixing shell 4 is connected to the top of the seabed valve 1 by no less than two pairs of tension bolts 6 for fixing the odometer transducer 2 for easy disassembly and maintenance.

[0025] As a preferred solution, further, the limiting ring 57 is a circular component made of soft rubber material bonded to the top of the fixed sleeve 56, and the limiting ring 57 and the transmission cable 3 are transitionally matched. On the one hand, the upper limiting ring 57 wraps and limits the transmission cable 3, and at the same time, due to its soft structure, it plays a deformation buffering role when the cable shakes slightly.

[0026] As a preferred solution, further, the buckle cover 53 is a plate with a columnar structure, and an adjusting knob 59 is sleeved on the outside of the buckle cover 53 to facilitate the rotation of the buckle cover 53.

[0027] From the above, it can be generally known that the cable safety protection mechanism of the ship speedometer, when installing the speedometer transducer 2, adopts a floating cable threader 5 set at the top position of the fixed shell 4 to wrap, limit and safely protect the transmission cable 3. The floating cable threader 5 adopts a spherical groove and a spherical groove structure to preset the angle of the transmission cable. At the same time, when encountering turbulence, the spherical rotation is utilized to make the cable automatically adapt to the bumpy posture, and the threading hole position is enlarged to avoid scratching the cable.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
