[0007] Furthermore, one end of the upper I-beam and the lower I-beam are vertically welded to the steel plate.

[0008] Furthermore, the upper I-beam and the lower I-beam are spaced apart, and a third I-beam is connected between the upper I-beam and the lower I-beam to reinforce the upper I-beam and the lower I-beam.

[0009] Furthermore, the upper I-beam and the lower I-beam are both composed of a plurality of I-beams arranged at intervals.

[0010] Furthermore, the I-beams of the upper layer are connected with first transverse I-beams, and the I-beams of the lower layer are connected with second transverse I-beams.

[0011] Furthermore, a first gasket is provided at one end of the upper I-beam and the lower I-beam, and the upper I-beam and the lower I-beam are welded to the stern through the first gasket.

[0012] Further, a third I-beam is vertically welded between the upper I-beam and the lower I-beam.

[0013] Furthermore, one end of the first I-beam is welded to the steel plate, and one end of the first I-beam away from the steel plate is welded to the upper I-beam.

[0014] Furthermore, second I-beams are welded to both sides of the upper I-beam and the lower I-beam respectively, and one end of the second I-beam away from the upper I-beam and the lower I-beam is welded to the stern through a second gasket.

[0023] It is welded by steel plate 1 and several I-beams to solve the problem of barge moving out of the port after the loading work at the dock is completed. It is installed at the left and right sterns of the barge to avoid interference between the jacket pile leg structure and the port tugboat assisting the barge to leave the port, causing financial or personal damage, ensuring the safety of the port tugboat and smoothly assisting the barge to leave the port.

[0024] Further, if Figure 1 As shown, one end of the upper I-beam 2 and the lower I-beam 3 are vertically welded on the steel plate 1; the upper I-beam 2 and the lower I-beam 3 are spaced apart, and a third I-beam 6 is connected between the upper I-beam 2 and the lower I-beam 3 to reinforce the upper I-beam 2 and the lower I-beam 3; the upper I-beam 2 and the lower I-beam 3 are both composed of a plurality of I-beams spaced apart.

[0025] In this embodiment, preferably, one end of the upper I-beam 2 and the lower I-beam 3 are vertically welded on the surface of the steel plate 1, the upper I-beam 2 is located on the upper part of the lower I-beam 3, and there is a certain distance between the upper I-beam 2 and the lower I-beam 3.

[0026] A plurality of third I-beams 6 are connected between the upper I-beam 2 and the lower I-beam 3, and the third I-beams 6 are located in the middle of the upper I-beam 2 and the lower I-beam 3. Preferably, the upper I-beam 2 and the lower I-beam 3 are respectively composed of a plurality of spaced-apart I-beams, and the I-beams are parallel to each other.

[0027] Further, if Figure 1 As shown, a first transverse I-beam 7 is connected between the I-beams of the upper I-beam 2, and a second transverse I-beam 8 is connected between the I-beams of the lower I-beam 3; a first gasket 9 is provided at one end of each of the upper I-beam 2 and the lower I-beam 3, and the upper I-beam 2 and the lower I-beam 3 are welded to the stern through the first gasket 9; and a third I-beam 6 is vertically welded between the upper I-beam 2 and the lower I-beam 3.

[0028] In this embodiment, preferably, a first transverse I-beam 7 is connected between the I-beams of the upper layer 2, and multiple first transverse I-beams 7 are located on the same straight line; a second transverse I-beam 8 is connected between the I-beams of the lower layer 3, and multiple second transverse I-beams 8 are located on the same straight line.

[0029] A first gasket 9 is welded to one end of the upper I-beam 2 and the lower I-beam 3 connected to the stern, and the upper I-beam 2 and the lower I-beam 3 are welded to the stern through the first gasket 9 to achieve an overall fixed connection; and a third I-beam 6 is vertically welded between the upper I-beam 2 and the lower I-beam 3, thereby fixing the upper I-beam 2 and the lower I-beam 3 and supporting the upper I-beam 2.

[0030] Further, if Figure 1 As shown, one end of the first I-beam 4 is welded to the steel plate 1, and the end of the first I-beam 4 away from the steel plate 1 is welded to the upper I-beam 2; the second I-beam 5 is welded on both sides of the upper I-beam 2 and the lower I-beam 3, respectively, and the end of the second I-beam 5 away from the upper I-beam 2 and the lower I-beam 3 is welded to the stern through the second gasket 10; the first transverse I-beam 7 and the second transverse I-beam 8 are arranged vertically parallel.

[0031] In this embodiment, preferably, one end of the first I-beam 4 is welded to the surface of the steel plate 1, and the other end is welded to the upper I-beam 2. The first I-beam 4 is arranged obliquely between the steel plate 1 and the upper I-beam 2 to further reinforce the upper I-beam 2.

[0032] The two sides of the upper I-beam 2 and the lower I-beam 3 are respectively welded to the second I-beam 5. Preferably, the second I-beam 5 is welded to the middle of the two sides of the upper I-beam 2 and the lower I-beam 3.

[0033] The barge takes a stern-to-side posture when the jacket is installed. After the loading is completed, the fixed rope with the dock is loosened. Since the barge cannot move out of the port by its own power, it needs to be assisted by multiple port tugboats to leave the port. However, due to the structural characteristics of the jacket, it is very easy for the tugboat to collide with it during the assisting operation, which may damage the tugboat hull and jacket structure. Therefore, a protective device is added to the stern of the barge, and the mooring pile position is widened outward by 3m to ensure the safety of the port tugboat and smoothly assist the barge to leave the port.

[0034] The transfer protection device based on the jacket loading and transportation is composed of a steel plate 1 on the side of the protection device away from the ship's side. The steel plate 1 and the hull are welded horizontally, vertically and diagonally by multiple I-beams to form a structure with sufficient stress strength to ensure that the support force of the port tugboat can effectively act on the hull, and no deformation will occur during the entire construction process. The overall I-beam structure is finally welded and reinforced on the port and starboard sides of the hull through multiple gaskets to ensure that the protection structure will not move left and right or up and down during the transfer process, resulting in the hull being unable to bear force and the transfer failing.

[0035] After the structural design was completed, relevant numerical simulations and hull strength checks were carried out. When the stress far exceeded that generated in actual operation was applied, the strength coefficient UC of the protective device met the requirements for rubbing and towing. When the hull was rubbing against the tugboat in the port, the structural strength of the ship's side met the transportation requirements and would not deform or sink.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
