Description

Technical Field

[0001] The utility model relates to the field of ship masts, and particularly relates to a folding mast with linkage and directional loading. Background Art

[0002] Generally, when there is no height limit requirement for an unmanned boat, a fixed mast structure is adopted to carry various communication devices. However, when the storage space is limited or there is a height limit during transportation, the fixed-height mast becomes a limiting factor. The unmanned boat in the current project needs to meet the use requirements of patrol and information communication with a remote control terminal over a long distance. A relatively high mast needs to be installed on the unmanned boat to carry various precision communication and navigation devices such as communication antennas, navigation radars, lidars, and optoelectronic tracking radars.

[0003] While effectively reducing the height of the mast to meet the storage requirements, we also need to ensure that the optoelectronic tracking radar equipment carried remains in a state of facing directly forward along the bow direction of the boat body. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a folding mast with linkage and directional loading, so as to solve the problems that a common mast cannot manually or automatically adjust the rotation angle and the equipment carried cannot observe forward along the bow direction after the mast is folded down.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows: it includes an installation base, on which there are two hinged mast frames. At the ends of the two mast frames, there is a hinged bearing platform seat. The two mast frames are connected to the installation base and the bearing platform seat at both ends to form a parallelogram mechanism.

[0006] On one side of the installation base, there is a hinged jacking mechanism. The end of the piston rod in the jacking mechanism is hinged to the middle of the mast frame, and is used to push the parallelogram mechanism to rotate.

[0007] Preferably, both ends of the mast frame are respectively hinged in the corresponding through holes on the installation base and the bearing platform seat through pin shafts.

[0008] Preferably, vertical limit blocks are fixedly arranged on both sides at the top of the installation base, and horizontal limit blocks are fixedly arranged on both sides at the bottom. When the mast frame is in the vertical state, it abuts against the vertical limit blocks, and when the mast frame is in the horizontal state, it abuts against the horizontal limit blocks, so that the rotation range of the mast frame is 0° - 90°.

[0009] Preferably, the jacking mechanism is a jacking mechanism, or a hydraulic cylinder, or a pneumatic cylinder.

[0010] Preferably, a middle platform seat is hinged between the two sides of the two mast frames, and radar equipment is carried on the middle platform seat.

[0011] Preferably, a communication and navigation device and an optoelectronic device are carried on the bearing platform seat.

[0012] The utility model provides a folding mast with a linkage type and a steerable carrying function. By remotely controlling the extension and retraction of the jacking mechanism, the mast body can rotate with the pin shaft of the mounting base as the reference, so as to adjust the total height of the mast, meet the storage requirements of the mast under the condition of extremely limited storage space on the mother ship, and improve the convenience and safety of mast operation; moreover, it can be applied to most current small surface ships and is controlled in a remote wireless control mode, with a wide range of application objects and usage scopes, convenient operation and easy implementation.

[0020] As Figures 1 to 5 shown, a folding mast with a linkage type and a steerable carrying function includes a mounting base 1. Two mast frames 2 are hinged on the mounting base 1. A bearing platform seat 5 is hinged at the end of the two mast frames 2. The two mast frames 2 are connected with the mounting bases 1 and the bearing platform seats 5 at both ends to form a parallelogram mechanism;

[0021] A jacking mechanism 3 is hinged on one side of the mounting base 1. The end of the piston rod in the jacking mechanism 3 is hinged to the middle of the mast frame 2 and is used to push the parallelogram mechanism to rotate. The bottom of the mounting base 1 is fixedly connected with the deck plane of the bow groove of the unmanned boat. The jacking mechanism 3 drives the parallelogram mechanism to rotate, thereby driving the bearing platform seat 5 at the end to move, so as to realize the deployment and contraction of the mast.

[0022] The parallelogram mechanism is adopted, and this system can complete complex motion conversion in a relatively small space, which is very suitable for installation on unmanned boats with limited space. The pushing mechanism can be driven to work through simple control signals, realizing the automatic deployment and recovery of the mast, greatly reducing the need for manual intervention. It can not only be used for unmanned boats, but also be modified and applied to other types of surface or underwater operation platforms according to actual needs. All components are carefully designed and strictly tested to ensure normal operation under harsh sea conditions, improving the overall stability and reliability of the system.

[0023] Preferably, both ends of the mast frame 2 are respectively hinged in the corresponding through holes on the installation base 1 and the bearing platform seat 5 through pin shafts. The mast frame 2 rotates with the pin shaft on the installation base 1 as a reference, so as to drive the bearing platform seat 5 at the end to rotate.

[0024] Both ends of the mast frame 2 are respectively connected to the through holes on the installation base 1 and the bearing platform seat 5 through pin shafts. This connection method allows the mast frame to rotate freely around the pin shaft, while maintaining a high connection strength, ensuring that it will not loosen or be damaged easily under the action of external forces such as wind and waves.

[0025] The mast frame 2 takes the pin shaft on the installation base 1 as the rotation reference. When the piston rod of the pushing mechanism 3 expands and contracts, it will push the mast frame 2 to rotate around this pin shaft, and then drive the bearing platform seat 5 to move together. The advantage of this design is that the deployment and retraction process of the mast can be accurately controlled to ensure smooth and accurate actions.

[0026] Through the pin shaft hinged connection method, the whole system has a compact structure and occupies a small space, which is especially suitable for application scenarios with limited space such as small unmanned boats. The piston rod directly acts on the middle part of the mast frame 2, which can effectively transmit power to the whole system and realize fast and smooth motion conversion. The pin shaft connection method is simple and reliable, which is convenient for daily inspection and maintenance, reducing the failure rate and maintenance cost.

[0027] Preferably, vertical limit blocks 101 are fixedly arranged on both sides of the top of the installation base 1, and horizontal limit blocks 102 are fixedly arranged on both sides of the bottom. When the mast frame 2 is in the vertical state, it abuts against the vertical limit blocks 101, and when the mast frame 2 is in the horizontal state, it abuts against the horizontal limit blocks 102, so that the rotation range of the mast frame 2 is 0° to 90°. The design of the limit blocks ensures that the mast frame 2 rotates accurately within the range of 0° to 90°, avoiding equipment damage caused by excessive rotation. The vertical limit blocks 101 and the horizontal limit blocks 102 respectively provide support at the two extreme positions of the mast frame 2, enhancing the stability of the system. The design of the limit blocks increases the safety of the system, preventing the mast frame 2 from moving accidentally due to external forces in a harsh environment. The limit block structure is simple, easy to check and replace, reducing the maintenance cost and difficulty.

[0028] Preferably, the pushing mechanism 3 is a pushing mechanism, a hydraulic cylinder, or a pneumatic cylinder. High precision and frequent operation: The pushing mechanism is recommended, especially in cases where high-precision sensors are installed or the mast needs to be frequently deployed and retracted. Large load and harsh environment: The hydraulic cylinder is recommended, especially in cases where large thrust is required or in strong wind and wave environments. Quick response and economical application: The pneumatic cylinder is recommended, especially in cases where quick action is needed or the budget is limited.

[0029] Preferably, a hinged middle platform seat 4 is provided between the two sides of the two mast frames 2, and radar equipment is mounted on the middle platform seat 4. The middle platform seat 4 is connected between the two mast frames 2 in a hinged manner. This connection method allows the middle platform seat 4 to adjust its angle as the mast frame 2 rotates, ensuring that the radar equipment can maintain a stable working state in different postures. The hinged connection also increases the flexibility of the system, enabling the middle platform seat 4 to independently adjust its angle to a certain extent to meet different usage requirements. Radar equipment can be mounted on the middle platform seat 4, and these equipment are usually used for tasks such as navigation, target recognition, and environmental monitoring. By installing the radar equipment on the middle platform seat 4, the height advantage of the mast can be fully utilized to improve the detection range and accuracy of the radar equipment.

[0030] Preferably, communication and navigation equipment and optoelectronic equipment are mounted on the bearing platform seat 5. The communication and navigation equipment includes communication equipment and navigation equipment, such as radio communication equipment, satellite communication equipment, GPS receivers, etc. These equipment are used to ensure smooth communication between the unmanned boat and other equipment or control centers, as well as precise positioning and navigation. The optoelectronic equipment includes infrared cameras, visible light cameras, laser rangefinders, etc. These equipment are used to provide visual assistance under night or harsh weather conditions to help the operator better understand the surrounding environment and improve safety and operation accuracy.

[0031] The bearing platform seat 5 is connected to the end of the mast frame 2 in a hinged manner. This connection method allows the bearing platform seat 5 to adjust its angle as the mast frame 2 rotates, ensuring that the mounted equipment can maintain a stable working state in different postures. The design of the bearing platform seat 5 enables the system to integrate a variety of equipment, not limited to communication and navigation equipment and optoelectronic equipment, and other sensors or equipment, such as meteorological monitoring equipment, sonar equipment, etc., can also be mounted according to needs.

[0032] By mounting communication and navigation equipment and optoelectronic equipment on the bearing platform seat 5, this design not only improves the flexibility and stability of the system but also expands its application range. Whether it is for high-precision and frequent operation scenarios or large-load and harsh environment tasks, different requirements can be met by selecting the appropriate pushing mechanism. This linkage type and directionally mountable collapsible mast system has a wide application prospect in water vehicles such as unmanned boats, and can significantly improve the navigation, communication, and environmental perception capabilities of unmanned boats.

[0033] The control end is the shore-based command and control center. There is a communication connection between the pushing mechanism and the shore-based command and control center, and the extension and retraction of the pushing mechanism are controlled through the shore-based command and control center. The control end is the switch button on the mother ship's bridge, which is electrically connected to the pushing mechanism, and the extension and retraction of the pushing mechanism are controlled through the switch button. The pushing mechanism has a self-locking function and can be locked after reaching the stroke position, ensuring the reliability and safety of the mast body during rotation and use.

[0034] Working process: When the unmanned boat sets out to sea, the shore-based command and control center remotely operates the push rod of the pushing mechanism to extend, causing the linkage mast body to rotate upward by 90° with the base pin as the reference until it is in a vertical state and then automatically locks and fixes; when the unmanned boat returns to the mother ship for storage, the shore-based command and control center remotely operates the pushing mechanism to retract, causing the mast body to rotate downward by 90° with the base pin as the reference until it is in a horizontal state. This solution makes the folding of the mast faster and more convenient.

[0035] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
