In order to facilitate the management and summary of the control devices of the thruster, a starting cabinet is required.

[0003] The existing ship thruster starting cabinet has deficiencies in controlling the high-voltage circuit and slowly starting the thruster at the same time, and its overall practicality needs to be improved. Utility Model Content

[0004] The utility model aims to provide a ship thrust starter cabinet which can effectively control the high voltage circuit and ensure that the thruster can be started slowly and stably, and has high practicability and stability.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] By adopting the above technical solution, it is possible to effectively prevent the electric spark generated at the moment when the control relay closes the high-voltage circuit from affecting the surrounding structures.

[0010] Furthermore, a mounting plate is provided inside the cabinet, a forward-reverse switch is fixedly mounted on an outer surface of the mounting plate, and the forward-reverse switch is electrically connected to the motor.

[0012] Furthermore, two installation grooves are provided on the side surface of the cabinet, and a connecting seat is installed inside each of the two installation grooves, two fans are fixedly installed on the side surface of one of the connecting seats, and a plurality of air outlet grooves are provided on the side surface of the other connecting seat.

[0013] By adopting the above technical solution, the rotation of the fan can be used to achieve the circulation of air inside the cabinet.

[0018] In summary, the beneficial technical effects of the utility model are:

[0019] 1. When starting the thruster, the utility model can close the power supply circuit of the thruster, and then use the forward and reverse switch to control the rotation of the motor. The rotation of the motor drives the screw to rotate. Since the conductive block is threadedly sleeved on the outside of the screw, and the conductive block is slidably sleeved on the outside of the slide rod, the rotation of the screw can cause the conductive block to move along the axial direction of the slide rod. At this time, the conductive block can adjust the contact point with the outer surface of the resistor, and then adjust the resistance in the power supply circuit of the thruster, so that the resistance changes from large to small, and then the current of the thruster changes from small to large, so as to avoid the thruster being instantly connected to the high-current circuit, so that the thruster can be started slowly, which can effectively improve the service life of the thruster and the overall practicality is effectively improved;

[0020] 2. The utility model can utilize the ceramic box seat to perform protective operation on the control relay through the setting of the ceramic box seat, so as to avoid the arc generated at the electrical joint of the control relay when the power supply resistance is minimum and damage the surrounding structure, and the inert gas filled in the ceramic box seat can effectively perform fire prevention operation on the electrical joint, thereby effectively improving the safety of the starter cabinet;

[0021] 3. When the utility model is working, the fan can be started, and the rotation of the fan can effectively drive the air flow. The flowing air passes through the connecting seat and the air duct at the bottom in sequence, and is finally discharged from the connecting seat at the top, so that the air inside the cabinet can circulate. Since a plurality of heat dissipation fins are arranged on the outer surface of the air duct, the air can be well cooled when passing through the inside of the air duct. This structure enables the starting cabinet to have a cooling structure and function, and the functionality and practicality are effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

The power supply circuit is then controlled by the forward / reverse switch 8 to rotate the motor 15. The rotation of the motor 15 drives the screw 14 to rotate. Since the conductive block 10 is threadedly sleeved on the outside of the screw 14, and the conductive block 10 is slidably sleeved on the outside of the slide bar 13, the rotation of the screw 14 can cause the conductive block 10 to move along the axial direction of the slide bar 13. At this time, the conductive block 10 can adjust the contact point with the outer surface of the resistor 12, and then adjust the resistance in the power supply circuit of the thruster, so that the resistance changes from large to small, and then the current of the thruster changes from small to large, avoiding the thruster from being instantly connected to a high-current circuit, so that the thruster can start slowly, which can effectively increase the service life of the thruster and effectively improve the overall practicality.

The interior of the ceramic box seat 5 is filled with inert gas, and the resistor 12 and the control relay 6 are both connected in series in the power supply circuit of the thruster. Through the setting of the ceramic box seat 5, the ceramic box seat 5 can be used to perform protective operations on the control relay 6 to avoid the arc generated at the electrical joint of the control relay 6 when the power supply resistance is minimum. Damage to the surrounding structure, and the inert gas filled in the ceramic box seat 5 can effectively perform fire prevention operations on the electrical joints, effectively improving the safety of the starting cabinet.

[0029] Reference Figure 1 , Figure 3Two mounting grooves are arranged on the side surface of the cabinet 1, and a connecting seat 2 is respectively installed inside the two mounting grooves, two fans 3 are fixedly installed on the side surface of one of the connecting seats 2, and a plurality of air outlet grooves are arranged on the side surface of the other connecting seat 2, an air duct 17 is arranged between the two connecting seats 2, and the two ends of the air duct 17 are respectively communicated with the inside of the two connecting seats 2, the air duct 17 is located outside the cabinet 1, and a plurality of heat dissipation fins 18 are fixedly connected to the side surface of the air duct 17, and a smoke alarm 16 is fixedly installed on the inner wall of the cabinet 1, wherein the fan 3 can be started during operation, and the rotation of the fan 3 can effectively drive the air flow, and the flowing air passes through the connecting seat 2 and the air duct 17 at the bottom in turn, and is finally discharged from the connecting seat 2 at the top, so that the air inside the cabinet 1 can circulate, and since a plurality of heat dissipation fins 18 are arranged on the outer surface of the air duct 17, the air can be well cooled when passing through the inside of the air duct 17, and this structure enables the starting cabinet to have a cooling structure and function, and the functionality and practicality are effectively improved.

[0030] Working principle: When in use, first install the starting cabinet at the designated position, then connect the external power supply and the thruster. When starting the thruster, close the control relay 6. At this time, the resistance of the resistor 12 connected in series in the thruster power supply circuit is relatively large. Then use the forward / reverse switch 8 to control the rotation of the motor 15. The rotation of the motor 15 drives the screw 14 to rotate. Since the conductive block 10 is threadedly sleeved on the outside of the screw 14 and the conductive block 10 is slidably sleeved on the outside of the slide bar 13, the rotation of the screw 14 can cause the conductive block 10 to move along the axial direction of the slide bar 13. At this time, the conductive block 10 can adjust the contact point with the outer surface of the resistor 12, thereby adjusting the thruster power supply circuit. The resistance in the cabinet causes the resistance to change from large to small, thereby causing the current of the thruster to change from small to large, preventing the thruster from being instantly connected to a high-current circuit, and allowing the thruster to start slowly. During the operation of the starting cabinet, the fan 3 is started, and the rotation of the fan 3 can effectively drive the air flow. The flowing air passes through the connecting seat 2 and the air duct 17 at the bottom in turn, and is finally discharged from the connecting seat 2 at the top, so that the air inside the cabinet 1 can circulate. Since a plurality of heat dissipating fins 18 are provided on the outer surface of the air duct 17, the air can be well cooled when passing through the inside of the air duct 17, thereby enabling the inside of the starting cabinet to be well cooled.
