Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of navigation equipment, in particular to a marine combined navigation positioning device. BACKGROUND

[0002] The combined navigation positioning device is combined with different navigation means, such as the combination of satellite navigation module and inertial navigation module, so as to complement the performance of various navigation means and obtain better navigation performance than single navigation means. The combined positioning navigation is commonly used on traffic carriers such as ships, vehicles and aircrafts.

[0003] The existing combined navigation positioning device includes, for example, Chinese patent publication No. CN213354858U, the name of which is "a combined navigation system assembled at the tail of the fuselage". The patent includes a combined navigation system base, a combined navigation system cover and an outer shell. The upper surface wall corner of the combined navigation system base is provided with a mounting hole, and the upper surface wall of the combined navigation system base is provided with a first weight reduction groove. The inner lower end of the combined navigation system cover is provided with a mounting groove. The combined navigation system assembled at the tail of the fuselage can achieve the weight reduction effect of the combined navigation system through the first and second weight reduction grooves, and avoid unnecessary restrictions caused by assembly with the fuselage.

[0004] The existing combined navigation positioning device is mainly composed of a host display part and an antenna part.

DETAILED DESCRIPTION

[0035] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0043] In still another embodiment of the present application, the cover assembly 5 comprises a ring frame 5.1 sealingly fitted to the outer shell of the combined navigation positioning body 1. The outer profile of the ring frame 5.1 is rectangular in structure, and the inner profile of the ring frame 5.1 is circular in structure. The back of the frame body of the ring frame 5.1 is fixedly installed with an elastic sealing unit 5.2, which can be adaptively fitted to the annular groove 4.2. The ring frame 5.1 is pressed by the pressing assembly 6, so that the elastic sealing unit 5.2 is deformed by being pressed by the ring frame 5.1 and the annular plate 4.1. In actual use, the ring frame 5.1 is aligned and attached to the annular plate 4.1, so that the elastic sealing unit 5.2 can be adaptively fitted to the annular groove 4.2.

[0044] In another embodiment of the present application, the pressing assembly 6 comprises a cover plate 6.1, one end of the cover plate 6.1 is hinged to the annular plate 4.1 through two hinge bases 6.2, and a protruding part 6.3 capable of extruding the ring frame 5.1 when the cover plate 6.1 is deflected is fixed on the cover plate 6.1.

Specifically, the cover plate 6.1 has two positions in its deflection stroke, which are a covering position in which the cover plate 6.1 is parallel to the frame opening surface of the ring frame 5.1, and an opening position in which the cover plate 6.1 is perpendicular to the frame opening surface of the ring frame 5.1. When the cover plate 6.1 is deflected towards the covering position, the protruding part 6.3 can further form a normal pressure on the ring frame 5.1 perpendicular to the surface of the annular plate 4.1, and the width direction of the protruding part 6.3 is perpendicular to the surface of the annular plate 4.1, so that the distance between the ring frame 5.1 and the annular plate 4.1 is further reduced, i.e. the space of the sealed space is reduced, so that the air in the sealed space is compressed, and the air pressure in the sealed space is increased. Similarly, when the cover plate 6.1 is deflected towards the opening position, the space of the sealed space is increased, and the air pressure in the sealed space is reduced. Therefore, in actual use, when the control panel on the navigation positioning body 1 needs to be operated, the cover plate 6.1 is turned to the opening position, and the air pressure in the sealed space is changed.

[0046] In actual use, when the cover plate 6.1 is located at the open position, the color liquid column 3.3 is located at the first position of the transparent tube 3.1 at this time, when the cover plate 6.1 is located at the covering position, the color liquid column 3.3 is located at the second position of the transparent tube 3.1 at this time, it is necessary to further explain that the frame body of the ring frame 5.1 is installed with a position sensing alarm device 7 for the color liquid column 3.3, when the cover plate 6.1 is located at the open position and the color liquid column 3.3 is not located at the first position of the transparent tube 3.1, and when the cover plate 6.1 is located at the covering position and the color liquid column 3.3 is not located at the second position of the transparent tube 3.1, the position sensing alarm device 7 will alarm at this time, preferably, the position sensing alarm device 7 can comprise a position sensor, a buzzer and a color diode, which is convenient for attracting the attention of the user.

[0050] In still another embodiment of the present application, the cover plate 6.1 further comprises a limit position, when the cover plate 6.1 is in the covering position, the side of the cover plate 6.1 facing the frame opening surface of the ring frame 5.1 is the inner side, and the side of the cover plate 6.1 away from the frame opening surface of the ring frame 5.1 is the outer side, when the cover plate 6.1 is in the limit position, it is formed by deflecting 180 degrees from the covering position around the hinge base 6.2, one end of the outer side of the cover plate 6.1 is fixed with an extrusion block 9, the extrusion block 9 is in a long strip structure, the width of the extrusion block 9 is greater than the width of the protruding part 6.3, the width direction line of the extrusion block 9 is perpendicular to the outer side of the cover plate 6.1, further, one end of the extrusion block 9 away from the cover plate 6.1 is provided with a cylindrical cavity 10, a piston column 11 is movably inserted in the cavity opening of the cylindrical cavity 10, one end of the piston column 11 extending into the cylindrical cavity 10 is fixed with a piston block 12, the other end of the piston column 11 is movably provided with a supporting wheel 13 capable of contacting the ring frame 5.1, the piston block 12 and the cavity bottom of the cylindrical cavity 10 are connected by a spring 14, the cavity bottom of the cylindrical cavity 10 is fixedly connected with a transparent thin strip tube 15, the transparent thin strip tube 15 is provided with a color liquid column 3.3, it is further needed to be explained that the outside of the transparent thin strip tube 15 is fixedly sleeved with a transparent cylindrical barrel 19, the inside of the transparent cylindrical barrel 19 is filled with transparent liquid, the transparent liquid can be selected as pure water, so as to form a lens effect on the transparent thin strip tube 15, which is convenient for observing the position of the color liquid column 3.3 in the transparent thin strip tube 15, the transparent cylindrical barrel is marked with a scale mark line, which is convenient for identifying the position of the color liquid column 3.3;

[0051] Preferably, the accommodating cylinder 4 is provided with a first air bag 16, the ring frame 5.1 is provided with a second air bag 17 on the center console, the first air bag 16 and the second air bag 17 are connected by a gas guide pipe 18, the gas guide pipe 18 is sealingly fixedly penetrated through the accommodating cylinder 4 and the shell of the center console, the second air bag 17 is in an elastic expansion state in a natural state, and the first air bag 16 is in a collapsed state in a natural state;

[0053] The color liquid column 3.3 in the transparent thin strip tube 15 has obvious movement in the middle, and the principle of judging the leakage of the sealed space in the containing cylinder 4 is that if the sealed space in the containing cylinder 4 leaks, the internal pressure of the sealed space in the containing cylinder 4 decreases, the reaction force of the ring frame 5.1 on the piston column 11 is composed of the sealing ring 5.22 and the pressure in the sealed space, and the pressure in the sealed space decreases, so the reaction force of the ring frame 5.1 on the piston column 11 decreases. At this time, the spring 14 which is elastically compressed and deformed pushes the piston column 11 to displace, so that the internal space of the cylindrical cavity 10 changes, thereby causing the position of the color liquid column 3.3 in the transparent thin strip tube 15 to change, thereby being able to realize the specific inspection of whether the sealed space has a slight gap and leakage condition. The whole detection process is also convenient and simple to operate, and realizes the sealing detection effect of different degrees through the cover plate 6.1 at different positions.
