Description

Technical Field

[0001] This utility model relates to the technical field of marine vehicle telegraph equipment, and in particular to a marine vehicle telegraph transmitter. Background Technology

[0002] Marine engine telegraph transmitters are a core component of ship control systems. They primarily convert bridge commands (such as forward, reverse, and stop signals) into electrical signals, which are then transmitted to the ship's main engine or propulsion system via the control system to achieve precise control of the ship's power system. Their performance directly affects the response speed, safety, and reliability of ship control.

[0003] Currently, most marine vehicle telegraph transmitters on the market use mechanical or contact sensors to acquire gear position signals. Common structures include mechanical contact switches, rotary potentiometers, or photoelectric encoders. However, in practical applications, existing technologies have the following key problems: the key adjustment of traditional vehicle telegraph transmitters mostly relies on mechanical limit screws or slider structures. The adjustment process requires repeated disassembly and calibration, which is cumbersome and inaccurate. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a marine vehicle telegraph transmitter to solve the problems of cumbersome key adjustment and inaccurate positioning in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides a marine engine telegraph transmitter, comprising a body, a key wheel rotatably connected to the body, multiple key slots distributed around the axis of the key wheel on the side wall of the key wheel for corresponding to different gear positions, and a key device disposed in the body that can be inserted into the key slots in coordination with the key wheel's rotation; the body is also provided with a handle that can drive the key wheel to rotate and a potentiometer rotatably connected to the body and rotating synchronously with the key wheel to detect the rotation angle of the key wheel; the key device includes a base fixedly installed in the body, a pin slidably connected to the base along the radial direction of the key wheel, and an elastic element disposed in the base that can drive the pin to move back and forth.

[0006] By adopting the above technical solution, the key wheel is rotated by pulling the handle back and forth. The position data is accurately collected by the synchronous rotation of the potentiometer and the key wheel. When the key wheel is rotated, the key positioner can be inserted into the key slot corresponding to the position. The key positioner achieves an elastic braking effect with the help of the synergistic action of the spring and the pin, thereby accurately adjusting the key position.

[0007] In one embodiment of this utility model, a main gear is coaxially arranged on the key wheel, and a secondary gear that meshes with the main gear is arranged inside the machine body. The potentiometer is coaxially arranged with the secondary gear, and the diameter of the secondary gear is smaller than that of the main gear.

[0010] By adopting the above technical solution, the key slots can be distributed on the key wheel according to the gear positions on the machine body. Through the chamfer on the key slot, when the key wheel rotates, the elastic element on the pin can be used to guide the pin to move to the outside of the key slot, thereby realizing the reciprocating movement of the pin.

[0011] In one embodiment of this utility model, the base is installed at an angle on one side of the key wheel, the pin is set at an angle of 45° next to the key wheel, and the end of the pin has a rounded corner.

[0012] By adopting the above technical solution, the pin is set at a 45° angle, which makes it easier for it to be positioned and inserted into the keyway, and the rounded corners at its ends make its movement smoother.

[0013] In one embodiment of the present invention, a connecting shaft is provided inside the machine body and is fixedly connected to and coaxially arranged with the key wheel. The connecting shaft extends to the outside of the machine body and is fixedly connected to the handle.

[0014] By adopting the above technical solution, a handle and connecting shaft drive the key wheel and main gear to rotate, thereby realizing gear adjustment.

[0015] In one embodiment of this utility model, the key wheel and the main gear are integrally formed, and the secondary gear is located directly below the main gear.

[0016] By adopting the above technical solutions, the structural distribution becomes more rational.

[0017] As described above, the marine engine telegraph transmitter of this utility model has the following beneficial effects: by pulling the handle back and forth, the key wheel is driven to rotate. Through the synchronous rotation of the potentiometer and the key wheel, the position data can be accurately collected. Furthermore, the key device can be inserted into the key slot corresponding to the gear position when the key wheel is rotated. The key device achieves an elastic braking effect with the help of the synergistic action of the spring and the pin, thereby accurately adjusting the key position. Attached Figure Description

[0025] like Figure 1 , Figure 2 As shown, this utility model provides a marine engine telegraph transmitter, including a body 1, a key wheel 2 rotatably connected to the body 1, multiple key slots 3 distributed around the axis of the key wheel 2 on the side wall of the key wheel 2 for corresponding to different gears, and a key device 4 disposed in the body 1 that can be inserted into the key slots 3 in coordination with the key wheel 2 for rotation and reciprocating.

[0026] The key positioner 4 includes a base 5 fixedly installed inside the body 1, a pin 6 slidably connected to the base 5 along the key position wheel 2, and an elastic element 7 installed inside the base 5 that can drive the pin 6 to reciprocate. The base 5 is installed at an angle to the underside of the key position wheel 2 at 45°. The pin 6 is slidably connected to the base 5, so that the pin 6 is set at 45°. The elastic element 7 is a spring, which is correspondingly set at the bottom of the pin 6. Under the elastic force of the elastic element 7, the pin 6 moves towards the key position wheel 2, so that the pin 6 is inserted into the key position groove 3 on the key position wheel 2, thereby achieving precise positioning of the key position groove 3.

[0027] Adjacent key slots 3 are arranged at the same angle on the side wall of the key wheel 2. In this embodiment, there are twelve key slots 3, and all key slots 3 are arranged on one side of the key wheel 2. The side wall of the key slot 3 is provided with an outwardly inclined chamfer 8, and the key slot 3 is connected to the outside along the axis of the key wheel 2. When the key wheel 2 rotates, the rounded corner at the end of the pin 6 moves to the outside of the key slot 3 under the guidance of the chamfer 8 of the key slot 3, and is compressed by the elastic element 7. When it rotates to another key slot 3, under the action of the elastic potential energy of the elastic element 7, the pin 6 is inserted into the key slot 3 to achieve precise positioning of the key slot 3.

[0028] like Figure 3 As shown, the machine body 1 is also equipped with a handle 9 that can drive the key wheel 2 to rotate and a potentiometer 10 that is rotatably connected inside the machine body 1 and rotates synchronously with the key wheel 2 to detect the rotation angle of the key wheel 2; the key wheel 2 is coaxially provided with a main gear 11, and the machine body 1 is provided with a secondary gear 12 that meshes with the main gear 11. The potentiometer 10 is coaxially provided with the secondary gear 12. The diameter of the secondary gear 12 is smaller than that of the main gear 11. The key wheel 2 and the main gear 11 are integrally formed, and the secondary gear 12 is located directly below the main gear 11.

[0029] The body 1 is provided with a connecting shaft 13 that is fixedly connected to the key wheel 2 and coaxially arranged. The connecting shaft 13 extends to the outside of the body 1 and is fixedly connected to the handle 9.

[0030] The main body 1 is equipped with a signaling device 14, which is coaxially arranged with the key wheel 2. The signaling device 14 can be an existing car telegraph signaling device 14.

[0031] In summary, this utility model achieves precise acquisition of position data by pulling the handle 9 back and forth to rotate the key wheel 2. The synchronous rotation of the potentiometer 10 and the key wheel 2 enables precise adjustment of the key position. Furthermore, the key positioner 4 can be inserted into the corresponding key slot 3 when the key wheel 2 is rotated. The key positioner 4 achieves an elastic braking effect with the help of the spring and the pin 6, thereby enabling precise adjustment of the key position.

[0032] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
