The specific implementation of the present invention is described in more detail below in conjunction with specific embodiments:

[0034] like Figure 1As shown, a mast-falling device 1 provided in an embodiment of the present invention is used to adjust the posture of a mast 11, including adjusting the mast 11 to a standing posture, or adjusting the mast 11 to a falling posture; specifically, the posture adjustment of the mast 11 can be achieved through three control modes: manual control mode, remote control mode and software automatic control mode. The boat equipped with the mast-falling device 1 is provided with a manual input control device, and the user can directly input a control command to control the posture of the mast 11; or the boat is provided with a communication component, and the user controls the mast 11 through a remote control; or the boat has its own control system, and the mast 11 changes its posture under the control of a preset program. It needs to be further explained that the boat can have at least two of the above three control modes at the same time to achieve multiple control modes.

[0035] The mast lowering device 1 of the present embodiment comprises: a mast 11 and a lowering assembly 10 for driving the mast 11 to rise and fall; the lowering assembly 10 comprises a slide rail 12, a sliding block 13, a connecting seat 14, a support rod 15 and a driving member 16, the slide rail 12 is used to be arranged on the navigation equipment 2, and can be specifically arranged on the deck of the navigation equipment 2; the sliding block 13 is slidably connected to the slide rail 12, and the sliding block 13 can move along the length direction of the slide rail 12; the connecting end of the mast 11 is slidably connected to the sliding block 13, and the connecting end of the mast 11 moves with the sliding block 13, and the movable end of the mast 11 extends in a direction away from the slide rail 12, and communication components and induction components, such as communication antennas, are usually arranged at the movable end of the mast 11; the connecting seat 14 is used to be arranged on the navigation equipment 2, and is located near the slide rail 1 2, the connecting seat 14 and the slide rail 12 are arranged at intervals; the connecting end of the support rod 15 is rotatably connected to the connecting seat 14, and the movable end of the support rod 15 is rotatably connected to the movable end of the mast 11. Since the connecting seat 14 and the slide rail 12 are arranged at intervals, and the connecting end of the mast 11 is connected to the slide rail 12, and the connecting end of the support rod 15 is connected to the connecting seat 14, that is, the connecting end of the mast 11 and the connecting end of the support rod 15 are arranged at intervals, and at the same time, the movable end of the mast 11 and the movable end of the support rod 15 are connected, that is, the mast 11, the support rod 15 and the heading device can be surrounded to form a triangular support structure; the driving member 16 is connected to the sliding block 13, and is used to drive the sliding block 13 to slide along the slide rail 12, and the sliding block 13 can drive the connecting end of the mast 11 to slide along the slide rail 12.

[0036] The working principle of the mast lodging device 1 of this embodiment is as follows:

[0037] like Figure 1 As shown, the driving member 16 drives the sliding block 13 to move along the sliding rail 12, and then the sliding block 13 drives the connecting end of the mast 11 to move along the sliding rail 12. When the connecting end of the mast 11 slides to the end of the sliding rail 12 close to the connecting seat 14, the movable end of the mast 11 is raised in height under the support of the support rod 15; Figure 2 As shown, when the connecting end of the mast 11 slides to the end of the slide rail 12 away from the connecting seat 14 , the movable end of the mast 11 is lowered in height due to the limiting connection of the support rod 15 .

[0038] It needs to be further explained that the connecting seat 14 can be set in the length direction of the slide rail 12, or it can not be set in the length direction of the slide rail 12. When the connecting seat 14 is set in the length direction of the slide rail 12, the connecting end of the mast 11 is connected to the sliding block 13 in a hinged manner. When the connecting seat 14 deviates from the length direction of the slide rail 12, the connecting end of the mast 11 is connected to the sliding block 13 in a universal connection manner.

[0039] The mast lodging device 1 provided in this embodiment has the following beneficial effects:

[0040] The driving member 16 drives the sliding block 13 to move along the sliding rail 12, and then the sliding block 13 drives the connecting end of the mast 11 to move along the sliding rail 12. When the connecting end of the mast 11 slides to the end of the sliding rail 12 close to the connecting seat 14, the movable end of the mast 11 is raised in height under the support of the support rod 15. At the same time, the mast 11, the support rod 15 and the navigation equipment 2 are combined to form a triangular support structure with strong stability; when the connecting end of the mast 11 slides to the end of the sliding rail 12 away from the connecting seat 14, the movable end of the mast 11 is lowered in height under the action of the limiting connection of the support rod 15. Similarly, the mast 11, the support rod 15 and the navigation equipment 2 are still combined to form a triangular support structure with strong stability.

[0041] In addition, the connecting end of the mast 11 moves along the slide rail 12, and the slide rail 12 is arranged on the navigation equipment 2. The surface of the navigation equipment 2 supports the slide rail 12, so that the slide rail 12 is not easily deformed under the gravity of the mast 11, thereby improving reliability during use.

[0042] In one embodiment, the mast lodging device 1 includes at least two lodging assemblies 10, the at least two lodging assemblies 10 are arranged opposite to each other, and a mast 11 is connected to the at least two lodging assemblies 10. Specifically, the mast 11 is in a "U" shape, both ends of which are connecting ends, and the two connecting ends are respectively connected to the sliding blocks 13 in the lodging assemblies 10 in a one-to-one correspondence. It can be understood that at least two lodging assemblies 10 support the mast 11, further improving the stability and reliability of the mast 11.

[0043] like Figures 3 to 5As shown, in one embodiment, the slide rail 12 is provided with a slide groove 121, and the sliding block 13 is provided with a slide table 131 accommodated in the slide groove 121, and the slide table 131 can move along the length direction of the slide groove 121. Specifically, the depth direction of the slide groove 121 is parallel to the plane of the slide rail 12 and perpendicular to the length direction of the slide rail 12, and the slide table 131 on the sliding block 13 extends along the depth direction of the slide groove 121 and is inserted into the slide groove 121 from the notch. The above design can increase the stability of the sliding block 13 when it is slidably connected to the slide rail 12.

[0044] Furthermore, the surface of the slide 131 that is connected to the groove wall of the slide groove 121 is provided with a wear block 132. In this embodiment, the wear block 132 is provided on the slide 131 to increase the durability of the slide 131, prevent the slide 131 from being worn too quickly when reciprocating in the slide rail 12, and reduce the life of the slide 131.

[0045] Furthermore, the wear-resistant block 132 includes a first wear-resistant block unit 1321, a second wear-resistant block unit 1322 and a third wear-resistant block unit 1323. The first wear-resistant block unit 1321 is connected to the bottom groove wall of the slide groove 121, and the second wear-resistant block unit 1322 and the third wear-resistant block unit 1323 are respectively connected to the two side groove walls of the slide groove 121. In this embodiment, the first wear-resistant block unit 1321, the second wear-resistant block unit 1322 and the third wear-resistant block unit 1323 are all detachably arranged on the slide 131, which is convenient for maintenance personnel to replace the wear-resistant block 132. At the same time, by respectively arranging multiple wear-resistant block units, it is also convenient for maintenance personnel to replace different wear-resistant block units according to the actual degree of wear.

[0046] In one embodiment, positioning holes 122 are provided at both ends of the slide rail 12, the openings of the positioning holes 122 face the inside of the slide rail 12, and positioning posts 133 are provided on the slide block 13 for inserting into the positioning holes 122. In this embodiment, when the slide block 13 moves to both ends of the slide rail 12, it means that the mast 11 is in a standing posture or a lying posture at this time, and the positioning posts 133 are offset by the hole wall of the positioning hole 122, so as to avoid lateral movement between the slide block 13 and the slide rail 12 during navigation, thereby causing the two to loosen, thereby reducing reliability.

[0047] In one embodiment, the slide rail 12 is provided with a sensor for sensing the position of the sliding block 13. It is understandable that by providing the sensor, the position of the sliding block 13 can be detected, and then the posture of the mast 11 can be detected, so that control information can be sent according to the posture of the mast 11, and automatic intelligent control can be realized, and the position detection of the sliding block 13 can be used to form a closed-loop control of the mast 11.

[0048] In one embodiment, a flexible cover 123 for covering the slide slot 121 is provided on the slide rail 12. It is understandable that the cover 123 can prevent foreign matter from entering the slide slot 121, thereby avoiding damage to the slide table 131 and the slide slot 121.

[0049] like Figure 6 As shown, in one embodiment, the driving member 16 includes a driving tube 161 and a telescopic rod 162. The driving tube 161 connects the connecting seat 14 and the slide rail 12. The telescopic end of the telescopic rod 162 is accommodated in the slide rail 12 and connected to the sliding block 13. The telescopic end of the telescopic rod 162 moves along the length direction of the slide rail 12 under the drive of the driving tube 161. Specifically, the driving tube 161 can be a cylinder or an oil cylinder. The driving tube 161 drives the telescopic rod 162 to move, thereby driving the sliding block 13 to slide, thereby driving the connecting end of the mast 11 to slide. The driving tube 161 is fixed between the connecting seat 14 and the slide rail 12, and its stability is high.

[0050] like Figure 7 As shown, this embodiment further provides a navigation device 2, comprising a body and the above-mentioned mast lowering device 1, wherein the mast lowering device 1 is arranged on the body.

[0051] The beneficial effects of the navigation device 2 provided in this embodiment are:

[0052] The driving member 16 drives the sliding block 13 to move along the sliding rail 12, and then the sliding block 13 drives the connecting end of the mast 11 to move along the sliding rail 12. When the connecting end of the mast 11 slides to the end of the sliding rail 12 close to the connecting seat 14, the movable end of the mast 11 is raised in height under the support of the support rod 15. At the same time, the mast 11, the support rod 15 and the navigation equipment 2 are combined to form a triangular support structure with strong stability; when the connecting end of the mast 11 slides to the end of the sliding rail 12 away from the connecting seat 14, the movable end of the mast 11 is lowered in height under the action of the limiting connection of the support rod 15. Similarly, the mast 11, the support rod 15 and the navigation equipment 2 are still combined to form a triangular support structure with strong stability.

[0053] In addition, the connecting end of the mast 11 moves along the slide rail 12, and the slide rail 12 is arranged on the navigation equipment 2. The surface of the navigation equipment 2 supports the slide rail 12, so that the slide rail 12 is not easily deformed under the gravity of the mast 11, thereby improving reliability during use.

[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
