[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a combined quick-closing valve control box for a ship comprises a control box 1 and an air bottle 2 installed in the control box 1, a three-way valve 3 is fixedly installed on the top of the air bottle 2, and a pressure gauge 20 is arranged on one side of the air bottle 2, a pressure relief pipe 4, an air supply pipe 5 and an air outlet main pipe 7 are respectively fixedly connected to the outside of the three-way valve 3, a spare pipe 6 is fixedly connected to the inside of the air supply pipe 5, the air supply pipe 5 is connected to the air compressor, and the spare pipe 6 is connected to the hand pump;

[0021] The outside of the main air outlet pipe 7 is connected to multiple groups of branch pipes 9, and quick-closing valves 10 are arranged outside the branch pipes 9. A box body 11 is installed inside the control box 1. The branch pipes 9 pass through the inside of the box body 11. A control component 8 is arranged inside the box body 11. The control component 8 is used to control the opening and closing of the multiple groups of quick-closing valves 10.

[0022] In the present embodiment, during the normal use of the control box 1, the air compressor normally replenishes air to the air bottle 2, and the air bottle 2 exhausts air outwardly through the combination of the main air outlet pipe 7 and the multiple groups of branch pipes 9. When the air compressor cannot normally replenish air to the air bottle 2, the crew can use the emergency hand pump to replenish air to the air bottle 2 to prevent power outages or air compressor failures. When the hand pump is also unable to normally replenish air to the air bottle 2 in time, the control component 8 in the box body 11 in the control box 1 is used, and the quick-closing valve 10 is quickly closed at the same time to cut off the internal channel of the branch pipe 9.

[0023] As an implementation method, Figure 2 and Figure 3As shown, the control component 8 includes a plurality of brackets 13 fixedly installed inside the box body 11, an eccentric wheel 12 is movably installed inside the plurality of brackets 13, one side of the eccentric wheel 12 abuts against a rocker arm 14, the rocker arm 14 is movably installed inside the box body 11, and two ends of the rocker arm 14 are respectively clamped with a sticking rod 15, one end of the sticking rod 15 is movably installed with a fastener 16 which is sleeved with the quick-closing valve 10, and the other end of the sticking rod 15 is fixedly connected with a spring 17, one end of the spring 17 is installed on the inner wall of the box body 11.

[0024] In this embodiment, when the quick-closing valve 10 needs to be closed, the eccentric wheel 12 inside the box body 11 is rotated. When the eccentric wheel 12 rotates, it contacts the rocker arm 14 on one side. After being pressed by the eccentric wheel 12, the rocker arm 14 tilts and drives the sticking rod 15 on one side to move. The fastener 16 at one end of the sticking rod 15 pulls the quick-closing valve 10 to rotate, and at the same time, the sticking rod 15 on the other side moves in the opposite direction and pushes the quick-closing valve 10 at the same time, so that the quick-closing valve 10 can be quickly closed.

[0025] As an implementation method, Figure 3 As shown, the sticking rod 15 is disposed symmetrically with respect to the center of the quick-closing valve 10 , and a stop column 18 corresponding to the swing rod 14 is installed on the sticking rod 15 .

[0026] In this embodiment, the stop column 18 installed on the sticking rod 15 drives the sticking rods 15 at both ends to move when the swing rod 14 tilts, and the sticking rods 15 on both sides can simultaneously act on the quick-closing valve 10 to close or open it.

[0027] As an implementation method, Figure 3 As shown, connecting frames 21 are detachably installed between the multiple groups of eccentric wheels 12 , and the connecting frames 21 are distributed between the eccentric wheels 12 in a mirror-image manner.

[0028] In this embodiment, multiple groups of eccentric wheels 12 are combined through a connecting frame 21, so that the quick-closing valves 10 in multiple groups of branch pipes 9 can be closed and opened at one time. At the same time, the detachable connecting frame 21 can be used to control the number of quick-closing valves 10 that need to be closed and opened, which is easy to adjust and can control the quick-closing valves 10 individually.

[0029] As an implementation method, Figure 3 As shown, the fasteners 16 are diagonally installed on the outside of the quick-closing valve 10 , and a push rod 19 is installed on the top of the eccentric wheel 12 , and the push rod 19 passes through the top of the control box 1 .

[0030] In this embodiment, the sticking rods 15 on both sides, one on the left and one on the right, can act on the quick-closing valve 10 at the same time. By using the fasteners 16 on the sticking rods 15, the quick-closing valve 10 is pulled to rotate when the sticking rods 15 move, so as to close or open it. The top rod 19 is at the top of the control box 1, which can control the closing of multiple quick-closing valves 10 at one time.

[0031] As an implementation method, Figure 2 and Figure 3 As shown, openings 22 are equidistantly formed inside the box body 11 , and the openings 22 correspond to the eccentric wheel 12 .

[0032] In this embodiment, the opening 22 of the box body 11 corresponds to the connecting frame 21. When it is necessary to control one group of quick-closing valves 10 separately, the connecting frame 21 is disassembled and the valves are closed or opened manually through the opening 22.

[0033] Working principle: When in use, during normal use of the control box 1, the air compressor normally supplies air to the air bottle 2, and the air bottle 2 exhausts air outward through the combination of the main air outlet pipe 7 and the multiple groups of branch pipes 9. When the air compressor cannot normally supply air to the air bottle 2, the crew can use the emergency hand pump to supply air to the air bottle 2 to prevent the ship from losing power or air compressor failure;

[0034] When the hand pump is also unable to replenish air to the air bottle 2 in time, the control member 8 in the box body 11 in the control box 1 is used to rotate the eccentric wheel 12 inside the box body 11. When the eccentric wheel 12 rotates, it contacts the swing rod 14 on one side. After being pressed by the eccentric wheel 12, the swing rod 14 tilts and drives the sticking rod 15 on one side to move. The fastener 16 at one end of the sticking rod 15 pulls the quick-closing valve 10, and at the same time, the sticking rod 15 on the other side moves in the opposite direction and pushes the quick-closing valve 10 to rotate, so that the quick-closing valve 10 can be quickly closed. At the same time, the connecting frame 21 between the eccentric wheels 12 combines multiple groups of eccentric wheels 12, and can close and open multiple groups of quick-closing valves 10 in the branch pipes 9 at one time, so that the quick-closing valves 10 can be quickly closed at the same time, and the internal channel of the branch pipe 9 can be cut off.
