However, the engine room bilge is more than half a meter below the iron plate, and the bilge angle irons and pipes are intricate and space is limited. When removing equipment or pipe bolts at the bottom of the bilge, personnel cannot enter the bilge to operate. In addition, some threaded connectors cannot be disassembled with ordinary wrenches due to obstruction by equipment or pipes. Even if the arm can reach the operating part, it is often difficult to exert force because the arm's force arm for applying force to the wrench is too short, resulting in inconvenience in disassembling threaded connectors.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0027] Example 1:
[0028] like Figures 1 to 3 As shown, the present application provides a special tool for disassembling a ship's bilge threaded connector, comprising a U-shaped wrench 3, an L-shaped sleeve connecting rod 1, and a positioning ring 2. The end of the L-shaped sleeve connecting rod 1 is connected to a sleeve body 4. The L-shaped sleeve connecting rod 1 is used to connect sleeve bodies 4 of different specifications. The sleeve body 4 is used to connect to the ship's bilge threaded connector (the sleeve body 4 is prior art and will not be described in detail in this application).
[0029] like Figure 2 and Figure 3 As shown, the positioning ring 2 is movably mounted on the outside of the L-shaped sleeve connecting rod 1, and the U-shaped wrench 3 is inserted on both sides of the positioning ring 2. The positioning ring 2 is used to control the U-shaped wrench 3 to be in the position of the L-shaped sleeve connecting rod 1. A screw hole 21 is provided on the outside of the positioning ring 2, and a bolt 22 is connected inside the screw hole 21. The bolt 22 is used to fix the positioning ring 2 to the outside of the L-shaped sleeve connecting rod 1. The part of the bolt 22 extending to the outside of the positioning ring 2 can block the U-shaped wrench 3.
[0030] like Figure 2As shown, the U-shaped wrench 3 includes a vertical steel pipe 31, a horizontal steel pipe 32 and a U-shaped steel pipe 33, which are connected by welding. The vertical steel pipe 31 and the horizontal steel pipe 32 are welded to form a T-shaped structure. The vertical steel pipe 31 has an outer diameter of 25 mm and a length of 400 mm. The horizontal steel pipe 32 has an outer diameter of 25 mm and a length of 400 mm. The U-shaped steel pipe 33 is made of threaded steel and has a diameter of 10 mm. The U-shaped steel pipe 33 made of threaded steel can increase its friction with the L-shaped sleeve connecting rod 1.
[0031] like Figure 2 As shown, the connecting end of the L-shaped sleeve connecting rod 1 and the sleeve body 4 is 50 mm long and 15 mm in diameter. It is connected to the sleeve body 4 through a square connector. The other end of the L-shaped sleeve connecting rod 1 has a diameter of 18 mm and a length of 300 mm. The surface is embossed with a prismatic pattern to increase the contact friction between it and the U-shaped steel pipe 33.
[0032] In this embodiment, first, a sleeve body 4 that is compatible with the ship's bilge threaded connector (nut) is selected and connected to the square connector end of the L-shaped sleeve connecting rod 1. Then, the positioning ring 2 is sleeved on the outside of the L-shaped sleeve connecting rod 1. The position of the positioning ring 2 on the L-shaped sleeve connecting rod 1 is reasonably adjusted according to the operating position. When the position is adjusted appropriately, the bolt 22 is tightened so that one end of the bolt 22 can contact the L-shaped sleeve connecting rod 1, thereby fixing the positioning ring 2 on the outside of the L-shaped sleeve connecting rod 1. Note that It is worth noting that the shorter the distance between the locating ring 2 and the square connecting head end of the L-shaped sleeve connecting rod 1, the better the stability of the applied force. Then, the U-shaped steel pipe 33 of the U-shaped wrench 3 is inserted on both sides of the locating ring 2 on the L-shaped sleeve connecting rod 1. Then, the operator can put the sleeve body 4 on the outside of the nut according to the threaded connection piece (nut) above the iron plate, and apply torque to the horizontal steel pipe 32 of the U-shaped wrench 3 with both hands according to the disassembly and assembly direction, so that the threaded connection piece (nut) can be twisted conveniently and easily for disassembly.
[0033] Example 2:
[0034] like Figure 4 and Figure 5 As shown, what is different from the first embodiment is that a positioning hole 11 is provided on the outside of the L-shaped sleeve connecting rod 1, and multiple groups of positioning holes 11 are provided along its length direction. A through hole 23 is provided on one side of the positioning ring 2, and a positioning column 24 slides through the inside of the through hole 23. One end of the positioning column 24 is adapted to the positioning hole 11, and the other end of the positioning column 24 is provided with a disc 26, which makes it convenient for the staff to pull the positioning column 24. A spring 25 is provided on one side of the disc 26, and one end of the spring 25 is connected to the outside of the positioning ring 2.
[0035] In this embodiment, by pulling the disc 26, it drives the positioning post 24 to move outward, and at the same time the spring 25 is stretched, and then the positioning ring 2 is sleeved on the outside of the L-shaped sleeve connecting rod 1, and one end of the positioning post 24 is aligned with the positioning hole 11 on the outside of the L-shaped sleeve connecting rod 1, and then the disc 26 is released, and under the elastic force of the spring 25, the disc 26 drives the positioning post 24 to be inserted into a group of positioning holes 11, thereby fixing the position of the positioning ring 2. When the position of the positioning ring 2 needs to be changed, it is only necessary to pull the disc 26 outward to drive the positioning post 24 to separate from a group of positioning holes 11, so that the positioning ring 2 can be slid, and then the positioning post 24 is inserted into another group of positioning holes 11 again under the elastic force of the spring 25, so as to complete the adjustment of the position of the positioning ring 2, making it more convenient to adjust the position of the positioning ring 2.
[0036] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
