Description

Technical Field

[0001] This utility model relates to the field of ship driving simulation equipment, specifically to a simulation engine telegraph that integrates fixed-pitch and variable-pitch propeller operation functions. Background Technology

[0002] In ship navigation training, the engine telegraph is a crucial piece of equipment used to simulate the speed and direction control of the ship's main engine. Currently, ships primarily use fixed-pitch and variable-pitch propellers, and the operating principles and methods of their engine telegraphs differ significantly. Therefore, ship navigation training often requires separate engine telegraphs for fixed-pitch and variable-pitch propellers, which not only increases the cost and space required for training equipment but also creates inconvenience for the layout and management of the training area. Furthermore, switching between different engine telegraphs hinders trainees from quickly mastering the operation skills of both propeller types, reducing training efficiency. Therefore, there is an urgent need for an engine telegraph that integrates the operation functions of both fixed-pitch and variable-pitch propellers. Utility Model Content

The handle assembly is rotatably connected to the panel, and its rotation outputs a gear operation signal corresponding to the gear position scale of the fixed-pitch propeller or the gear position scale of the variable-pitch propeller. The integrated control module is installed in the lower housing and includes: a propeller selection module, a fixed-pitch propeller control module, and a variable-pitch propeller control module; The propeller selection module is electrically connected to the external simulation training system. It outputs a mode selection signal based on the ship type signal issued by the external simulation training system, and activates the fixed-pitch propeller control module or the variable-pitch propeller control module based on the mode selection signal. The activated control module receives the corresponding gear operation signal and converts it into a gear control signal for the corresponding propeller type. The signal processing module is electrically connected to the output terminals of the fixed-pitch propeller control module and the variable-pitch propeller control module. It is used to process the control signals of the fixed-pitch propeller and the variable-pitch propeller and transmit them to the external simulation training system.

[0005] Furthermore, the telegraph body has two handle assemblies, which are used to simulate port and starboard operations of a ship, respectively. Each handle assembly includes: a handle and a mechanical transmission mechanism; The mechanical transmission mechanism includes: a central shaft, gear A, and a transmission gear; The axis of the central shaft is parallel to the axis of the dial, one end of which is located below the dial, and the other end extends out from the side of the dial and is connected to the handle for transmission. Gear A is coaxially sleeved outside the central shaft, and the two are connected by a transmission. The transmission gear meshes with gear A, and the fixed-pitch propeller control module and the variable-pitch propeller control module generate corresponding gear operation signals based on the rotation angle of the transmission gear.

[0006] Furthermore, the central shaft is provided with a shoulder, which provides axial restraint to gear A.

[0007] Furthermore, each mechanical transmission mechanism also includes: a spring locating pin; Each of the central shafts has positioning holes arranged circumferentially on its shoulder, corresponding one-to-one with the scale of the gear position. The positioning hole includes two depths, corresponding to two different lengths of graduations on the dial, to produce two different tactile sensations.

[0008] Furthermore, the vehicle telegraph body also includes a longitudinal physical isolation mechanism that is detachably connected to the bottom of the panel; The internal space of the lower housing is divided into two independent chambers by a longitudinal physical isolation mechanism, and the mechanical transmission mechanisms of the two handle assemblies are located in the two chambers respectively.

[0010] Furthermore, the vehicle telegraph body also includes two pointers for indicating the scale corresponding to the current gear position; The two pointers are mounted on two central axes, which rotate with the central axes.

[0011] Furthermore, the signal processing module includes: a chip, a fixed-pitch propeller signal interface socket, and a variable-pitch propeller signal interface socket; The chip is mounted inside the lower housing of the vehicle body via a metal heat sink bracket; Both the fixed-pitch propeller signal interface socket and the variable-pitch propeller signal interface socket are electrically connected to the input terminal of the chip, and are respectively connected to the fixed-pitch propeller control module and the variable-pitch propeller control module. The fixed-pitch propeller signal interface socket and the variable-pitch propeller signal interface socket use different pin arrangements.

[0012] Furthermore, signal isolation plates are respectively fitted over the fixed-pitch propeller signal interface seat and the variable-pitch propeller signal interface seat.

[0013] Furthermore, the signal processing module also includes: a communication interface; The communication interface is electrically connected to the output of the chip and is used for signal transmission with an external simulation training system.

When the spring positioning pin is inserted into the positioning hole, the operator can feel a clear jerking sensation. The two positioning holes with different depths produce two kinds of jerking sensation, so that the operator can clearly perceive the gear position corresponding to different blade types through different jerking sensations, and can also prevent sudden changes in speed caused by misoperation.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: This embodiment provides a simulated engine telegraph that integrates fixed-pitch and variable-pitch propeller operation functions, such as... Figures 1 to 6 As shown, it includes: a car telegraph body 1 and an integrated control module 17 and a signal processing module 12 disposed inside the car telegraph body 1; The main body 1 of the train telegraph is the operating carrier of the entire analog train telegraph and is used to output gear operation signals; the gear operation signals include: the gear operation signals of the fixed pitch propeller and the gear operation signals of the variable pitch propeller. The integrated control module includes: a propeller selection module, a fixed-pitch propeller control module, and a variable-pitch propeller control module; The propeller selection module is electrically connected to the external simulation training system. It outputs a mode selection signal based on the ship type signal issued by the external simulation training system, and activates the fixed-pitch propeller control module or the variable-mass control module based on the mode selection signal. Both the input terminals of the fixed-pitch propeller control module and the variable-pitch propeller control module are electrically connected to the signal output terminal of the vehicle body 1 to receive corresponding gear position operation signals. Specifically, when the fixed-pitch propeller control module is enabled, it receives the gear position operation signal of the fixed-pitch propeller and converts it into a gear position control signal of the fixed-pitch propeller. When the variable-pitch propeller control module is enabled, it receives the gear position operation signal of the variable-pitch propeller and converts it into a gear position control signal of the variable-pitch propeller. The signal processing module 12 is electrically connected to the output terminals of the fixed-pitch propeller control module and the variable-pitch propeller control module. It is used to process the control signals of the fixed-pitch propeller and the variable-pitch propeller and transmit them to the external simulation training system. The signal processing module 12 includes: a chip, a dual-recording signal interface socket, and a communication interface. The chip is mounted inside the vehicle telegraph body 1 via a metal heat sink bracket; The dual-signal interface socket is electrically connected to the input terminal of the chip; such as Figure 6 As shown, the dual-channel signal interface socket includes a fixed-pitch propeller signal interface socket 10 and a variable-pitch propeller signal interface socket 11. The chip is electrically connected to the output terminal of the fixed-pitch propeller control module through the fixed-pitch propeller signal interface socket 10 to receive the gear position operation signal of the fixed-pitch propeller. The variable-pitch propeller signal interface socket 11 is used to connect to the variable-pitch propeller control module to receive the gear position operation signal of the variable-pitch propeller. In this embodiment, the fixed-pitch propeller signal interface socket 10 and the variable-pitch propeller signal interface socket 11 adopt different pin arrangements. Specifically, the fixed-pitch propeller signal interface socket 10 has three pins, and the variable-pitch propeller signal interface socket 11 has four pins. The difference in physical structure prevents mis-interlocking between the two. Signal isolation plates are respectively sleeved on the fixed-pitch propeller signal interface socket 10 and the variable-pitch propeller signal interface socket 11 to reduce electromagnetic interference between the two signals. The signal isolation plates are preferably made of epoxy resin. The fixed-pitch propeller signal interface socket 10 and the variable-pitch propeller signal interface socket 11 transmit the gear position operation signal to the chip through their respective pins. The chip processes and converts the received signal. The communication interface is electrically connected to the output of the chip, and the chip transmits signals to the external simulation training system through the communication interface. In this embodiment, the communication interface is preferably a USB interface, and shielded twisted-pair cable is used to transmit signals. The shielded twisted-pair cable is equipped with snap-on anti-pull-out connectors at both ends, and rubber sealing rings are provided at the connectors to ensure that the cable will not fall off when transmitting radio waves, while also having a certain degree of waterproof and dustproof capability. The simulated vehicle telegraph transmits the processed control signals to the external simulation training system through the communication interface, and at the same time receives relevant information (ship operation status, etc.) fed back by the external simulation training system to achieve a more realistic simulation training effect. As an example, the telegraph body 1 has a cable slot inside to separate the transmission cables of the fixed pitch propeller and the variable pitch propeller, so as to avoid the signal attenuation caused by the cable tangling. like Figures 1 to 4 As shown, the car clock body 1 includes: a panel 9, a dial 3, a lower housing, two handle assemblies, two mechanical transmission mechanisms, and two pointers 2; The bottom of panel 9 is fitted with a lower housing, forming an installation space. The propeller selection module, fixed-pitch propeller control module, variable-pitch propeller control module, and signal processing module 12 are installed in this installation space. In this embodiment, the metal heat sink bracket is installed in the lower housing by a threaded connection to ensure that the chip can still work stably in the vibration environment of ship radio waves, and to avoid signal processing failure due to structural loosening. The cable slot is located inside the lower housing. The dial 3 is mounted on the top of the panel 9 and has an arc-shaped structure. The front of the dial 3 has three circumferential areas: a forward gear area, a neutral gear area, and a reverse gear area. The neutral gear area is located between the forward and reverse gear areas and includes: a neutral gear mark; both propeller types (fixed-pitch and variable-pitch propellers) share a single neutral gear mark; the forward gear area includes multiple forward gears corresponding to different forward speed levels; the reverse gear area includes multiple reverse gears corresponding to different reverse speed levels; each forward gear includes a gear mark for a fixed-pitch propeller and a gear mark for a variable-pitch propeller, and each reverse gear includes... This includes: pitch position scales for fixed-pitch propellers and pitch position scales for variable-pitch propellers; the pitch position scales for variable-pitch propellers and variable-pitch propellers have different lengths; as an example, the dial has a total of twenty-one positions, including: ten forward positions, ten reverse positions, and one neutral position; the forward positions include: twenty forward position scales, the reverse positions include: twenty reverse position scales, and the neutral position includes: one neutral position scale; the forward position scales are indicated in white, and the reverse position scales are indicated in red; this color marking method allows the crew to quickly distinguish between forward and reverse operations, thereby reducing turning errors; The two handle components are used to simulate port and starboard maneuvers of a ship, respectively; such as Figure 4 and Figure 5 As shown, each handle assembly includes: a handle 4, a mechanical transmission mechanism, and an angle sensor; two handles 4 are located on opposite sides of the axial direction of the dial 3, and each handle 4 is rotatably connected to the panel 9 via the mechanical transmission mechanism; the mechanical transmission mechanism includes: a central shaft 15, a gear A16, and a transmission gear 13; the axial direction of the central shaft 15 is parallel to the axial direction of the dial 3, one end of the central shaft 15 is located below the dial 3 and is rotatably connected to the panel 9 via a bearing, and the other end of the central shaft 15 extends out from the side of the dial 3 and is connected to the handle 4 via transmission; the two central shafts 15 are designed as independent shaft systems, each equipped with an independent bearing and mechanical transmission mechanism, so that there is no connection between the two central shafts 15, which can structurally cut off the mutual interference of torque transmission; in this embodiment, the central shaft 15 and the handle 4 are connected via spline transmission, thereby ensuring stable torque transmission; the fit tolerance grade between the central shaft 15 and the handle 4 is H7 / h6, thereby avoiding excessive gap between the two shafts that would cause scale offset; in this embodiment, each handle 4 is connected to a handle head 5 at the grip, making it easy to operate the handle 4; Two pointers 2 are respectively mounted on two central shafts 15. The pointers 2 rotate with the central shafts 15, thereby pointing to the corresponding scale on the dial 3. Gear A16 is coaxially sleeved on the outside of the central shaft 15, and the two are connected by transmission. As an example, the central shaft 15 is provided with a shoulder along its circumference. The shoulder forms an axial limit on gear A16, which can effectively prevent the gear from axial transmission during long-term operation, thereby improving the stability of the car clock. The transmission gear 13 meshes with the gear A16; the rotation angle of the transmission gear 13 is detected by the angle sensor to form a gear operation signal; the gear operation signal is sent to the fixed pitch propeller control module and the variable pitch propeller control module through the signal output terminal of the angle sensor (i.e. the signal output terminal of the head unit 1); In this embodiment, both gear A16 and transmission gear 13 are preferably sheared cylindrical gears with a module of 2 and a number of teeth of 20-40, and their material is preferably tempered 45 steel; the transmission ratio between the two is preferably 1:2, so as to ensure that the rotation angle of the central shaft 15 corresponds linearly to the rotation speed of the paddle. As an example, each mechanical transmission mechanism also includes: a spring positioning pin 14; and positioning holes that correspond one-to-one with the scale of the gear position are arranged on the shoulder of each central shaft 15 along its circumference; wherein the positioning holes include two depths, corresponding to the long scale and the short scale on the dial 3 respectively. The spring positioning pin 14 is located on the back of the dial 3 and installed inside the lower housing. When the operator selects a gear by turning the handle 4, the central shaft 15 rotates with the handle 4. When the central shaft 15 rotates to the gear mark of the target gear, the spring positioning pin 14 pops up and engages in the corresponding positioning hole, thereby locking the central shaft 15 in that gear. When the spring positioning pin 14 engages in the positioning hole, the operator can feel a distinct jolt. The two positioning holes of different depths produce different jolts, allowing the operator to clearly perceive the gear corresponding to different propeller types through different jolts, preventing sudden changes in speed due to misoperation. In this embodiment, the deep positioning hole corresponds to the long scale (i.e., the gear of the fixed-pitch propeller), and the shallow positioning hole corresponds to the short scale. As an example, the lower housing is provided with a longitudinal physical isolation mechanism 18, which divides the internal space of the lower housing into two independent chambers, thereby separating the mechanical transmission mechanisms of the two handles 4. This ensures that if one mechanical transmission mechanism fails (such as gear jamming), it will not affect the normal operation of the other transmission device. In this embodiment, the longitudinal physical isolation mechanism 18 is detachably connected to the panel 9 by bolts. The material of the longitudinal physical isolation mechanism 18 is preferably stainless steel, and its thickness is preferably 3mm. As an example, the main body 1 of the vehicle clock also includes: a cover 7; the cover 7 is installed over the dial 3 and the pointer 2 and is fixed to the panel 9 by the cover pressure plate 8; the cover 7 is made of transparent plastic material and protrudes 5mm above the top of the dial plate, which can effectively prevent the operator from accidentally touching it and affecting the operation, and does not affect the confirmation of the gear position. As an example, each handle 4 is provided with eccentric limiting posts 6 on both sides to limit the rotation angle of the handle 4, thereby limiting the rotation angle of the handle 4. In this embodiment, the dial 3 is composed of a transparent acrylic plate and a PVC film covering it, and the gear scale is printed on the PVC film; the handle 4 and the eccentric limit post 6 are both made of steel, and their outer surfaces are provided with a chrome-plated layer; the cover plate 8 and the aluminum panel 9 are both made of aluminum alloy, and their outer surfaces are anodized to black; the handle head 5 is made of nylon, and its outer surface is provided with a black glossy paint layer.

[0026] Working principle: When the propeller selection module determines that the current propeller type is fixed-pitch propeller, it activates the fixed-pitch propeller control module. The operator rotates the handle 4 to the fixed-pitch propeller position scale, and the rotation angle of the central shaft 15 is converted into a fixed-pitch propeller position operation signal, which is transmitted to the fixed-pitch propeller control module. The fixed-pitch propeller control module processes the fixed-pitch propeller position operation signal according to the fixed-pitch propeller control logic and sends the generated fixed-pitch propeller control command to the signal processing module 12. After the signal processing module 12 encapsulates the command according to the protocol, it sends it to the external simulation training system through the communication interface, thereby realizing the simulated control of the fixed-pitch propeller thruster. When the propeller selection module determines that the current propeller type is variable pitch propeller, it activates the variable pitch propeller control module. The operator rotates the handle 4 to the gear position scale of the variable pitch propeller, and the rotation angle of the central axis 15 is converted into a gear position operation signal and transmitted to the variable pitch propeller control module. The variable pitch propeller control module processes the gear position operation signal of the variable pitch propeller according to the variable pitch propeller control logic, and sends the generated variable pitch propeller control command to the signal processing module 12. After the signal processing module 12 encapsulates the command according to the protocol, it sends it to the external simulation training system through the communication interface, thereby realizing the simulated control of the variable pitch propeller thruster.

[0027] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
