The fixed bottom structure is welded to the hull deck, and the reinforcing foot supports 2 are respectively welded to the hull deck and the fixed bottom structure to achieve the purpose of strengthening support.

[0033] The foldable upper structure includes a bottom disc and an upper support body. The bottom disc has the same shape as the top disc, and the bottom disc and the top disc are hinged at the edge to achieve folding around one side. One end of the upper support body is coaxially fixed on the bottom disc, and the other end extends outwardly from the circumference of the bottom disc as a free end. The M-shaped base is tightly fixed on the upper surface of the free end. A top outlet hole 8 is provided on the side wall of the bottom disc, and the top outlet hole 8 is connected to the circular hole on the top disc. A top fixing ring 10 is provided at the edge of one side of the upper surface of the bottom disc away from the upper support body. The outer side of the top fixing ring 10 is a hinge 4 connecting the bottom disc and the top disc. A plurality of fastening holes 11 are correspondingly provided on the bottom disc and the top disc. The top outlet hole 8 is located on the side wall of the bottom disc and at the bottom center of the upper support body.

[0034] A tying flat bar 9 is provided at the bottom of the upper support body. The tying flat bar 9 is in the shape of a long strip and is arranged along the bottom center line of the upper support body. The cable connected to the 4G radar passes through the bottom inlet hole 3, the inner cavity of the bottom cylindrical body, the circular hole of the top disc body, and the top outlet hole 8 on the bottom disc body in sequence, and enters the M-shaped base 1 through the tying flat bar 9 along the bottom of the upper support body.

[0035] The described M-shaped base 1 is a square plate-like structure, with a M-shaped slot in the middle of the square plate-like structure, and a round hole in the middle of the M-shaped slot for the cable to pass through. The M-shaped slot can be adapted to various sizes of 4G radar installation holes to the maximum extent, and the round hole in the middle can pass the cable, so that the cable can be connected to the 4G radar from the bottom. The described M-shaped base 1 is fixed to the free end of the upper support body by welding, and a center hole for the cable to pass through is provided on the free end, and the center hole is aligned with the round hole of the M-shaped slot.

[0036] Under normal conditions, when the ship is sailing in waters without restrictions, the fixed lower structure is welded to the hull deck, the reinforcing foot brace 2 is welded and fixed to the hull deck and the fixed lower structure respectively, and the foldable upper structure is installed and fixed to the fixed lower structure, and the bolts 5 pass through the fastening holes 11 and are fixed with nuts 6, that is, nuts and bolts are used to pass through the fastening holes for connection, so that the foldable upper structure is firmly connected to the fixed lower structure. The free end of the upper support body in the foldable upper structure extends out of the outside of the hull, so that the 4G radar fixed on the M-shaped base 1 is extended out of the outside of the hull for detection.

[0037] like Figure 5 and Figure 6As shown, in the folded state, when the ship enters the restricted area including the Panama Canal, the foldable upper structure is folded upward from the fixed lower structure, the 4G radar on the M-shaped base 1 is folded and retracted onto the hull deck, and the top fixing ring 10 and the bottom fixing hole 3 are respectively connected by a container lashing rod to achieve fixation after folding. In the folded state, the foldable upper structure rotates 90 degrees upward around the hinge 4 on the top disc of the fixed lower structure.

[0038] A ship is provided with the above-mentioned base device to realize the foldable function of the 4G radar in a restricted area, wherein the restricted area includes canal waterways including the Panama Canal.

[0039] When the base device of the present invention is installed, the fixed bottom structure is welded on the hull deck, and the reinforcing foot support 2 is welded to the hull deck and the fixed bottom structure respectively, so as to achieve the purpose of strengthening the support. The cable passes through the deck from under the deck and enters the interior of the 4G radar folding base device of the present invention through the bottom wire inlet hole 7. After the cable is coiled inside with a margin, it passes through the top wire outlet hole 8, is tied to the tying flat bar 9 for fixing, and then passes through the round hole on the M-shaped base 1 and enters the 4G radar body from the bottom for wiring.

[0040] When the base device of the present invention is actually used:

[0041] When the ship is sailing in waters without restrictions, the foldable top structure fits tightly with the fixed bottom structure, and bolts 5 and nuts 6 are used to pass through the fastening holes 11 of the two to fasten them together. At this time, the 4G radar extends out from both sides of the ship's side, the bow and the stern to perform normal detection activities.

[0042] When the ship enters a restricted area such as the Panama Canal, loosen the bolts 5 and nuts 6. Rotate the foldable superstructure 90 degrees on the vertical plane around the hinge 4. Use the container lashing rod to connect the top fixing ring 10 and the bottom fixing hole 3 respectively to fix them. At this time, the 4G radar is on the inside of the ship's side, bow and stern, meeting the maximum length and width requirements.

[0043] The present invention can help ships to quickly fold up the 4G radar when passing through such restricted areas, so that it does not exceed the width and length of the ship, helping to meet the requirements. After passing through, it can be quickly restored without the need to calibrate the 4G radar again.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it.
