Description

Technical Field

[0001] The utility model relates to the technical field of shipping ship equipment, in particular to a double-plate secondary flow-guiding type marine leakage protection device. Background Art

[0002] Ship equipment refers to any movable but non-consumable items used on board except for ship spare parts. An operating ship must be equipped with a variety of equipment, which are used to complete the ship's navigation, berthing, loading and unloading of cargo, and other production operations, and to ensure the safety of the ship and personnel. The main equipment of the ship includes power equipment, operating equipment, loading and unloading equipment, and safety equipment. These equipment need to be driven by related electrical equipment and systems during operation. In the electrical equipment of the ship, the transformer plays the role of transmitting and converting electrical energy to ensure that the electrical energy in the electrical system is sufficient and stable.

[0003] During the use of the marine transformer in the prior art, it is necessary to isolate and protect the marine transformer through a protective box. However, placing the marine transformer inside the box for use can have a protective effect on it. However, during the use of the marine transformer, it is easily affected by the marine weather environment. The marine working conditions make the marine transformer more worn than when it is used on land. At the same time, the emergency measures that can be taken when there is a risk of leakage are limited. Once the transformer on the ship leaks, the protective casing of the marine transformer carries current. Since the marine transformer is located inside the protective box and the protective box does not have the function of protecting against leakage, it is not easy for the staff to promptly detect the leakage phenomenon generated by its casing. When there is leakage in the shell of the marine transformer, if the staff opens the protective box and accidentally touches the shell of the marine transformer, it is easy to cause danger, and the safety of the users on the ship cannot be guaranteed, which is easy to cause serious consequences. At present, there is a lack of marine-related anti-leakage measures that can be adapted to the long-term humid conditions on board. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a double-plate secondary flow-guiding marine leakage protection device.

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

[0007] Preferably, two grooves are symmetrically formed on the inner bottom surface of the box body, screw rods are rotatably installed inside the two grooves, and moving blocks are installed on the outer walls of the two screw rods.

[0008] Preferably, the tops of the two moving blocks are rotatably mounted with rotating blocks through screws, one end of the two screws passes through the moving blocks and is threadedly mounted with nuts, and the ends of the two rotating blocks away from the moving blocks are rotatably connected to the moving plates close to them through damping shafts.

[0009] Preferably, heat dissipation nets are installed on both side outer walls of the box body, and inclined surfaces are arranged on the outer walls of the box body close to the bottom ends of the two heat dissipation nets.

[0010] Preferably, outer walls of the two movable plates on one side away from each other are both installed with rubber pads, and outer walls of the two rubber pads on one side away from the movable plates are both installed with a plurality of protrusions adapted to the meshes of the heat dissipation net.

[0011] Preferably, a rectangular groove is provided on the outer wall of one side where the two movable plates are close to each other, and a rotating plate is rotatably installed inside the two rectangular grooves, and the two rotating plates and the movable plate are both made of conductive metal material.

[0012] Preferably, insulation monitors are installed on the top of the two movable plates through two second bolt threads, and the two insulation monitors are connected to the insulation resistor on the top of the marine transformer through connecting wires.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, when the marine transformer is installed inside the box for use, the two screw rods are controlled to drive the two movable plates to move together in the direction of approaching each other, until the two movable plates are respectively in contact with the outer walls on both sides of the marine transformer. If leakage occurs in the marine transformer, the leakage current located in the shell of the marine transformer will be guided into the wire with the help of the two movable plates, and the current will be introduced into the hull through the wire, triggering the grounding protector or leakage protector preset inside the box to start, thereby cutting off the power supply of the marine transformer, and protecting the safety of the marine transformer itself and the personal safety of the staff who accidentally touch the marine transformer.

[0015] In the utility model, the insulation resistance of the insulation resistance on the top of the marine transformer can be monitored in real time by the insulation monitor. When the insulation resistance is lower than the set value, the insulation monitor will transmit a signal to the central controller, and the central controller will control the alarm to sound an alarm, reminding relevant staff to maintain the insulation status of the marine transformer in time to avoid failure of the marine transformer in subsequent work.

[0016] In the utility model, if the environment outside the box is relatively humid, the two screw rods are controlled to drive the two movable plates to move in directions away from each other, until the rubber pads on the outer walls of the two movable plates on the away side are tightly abutted against the inner walls of the two heat dissipation nets, thereby being able to seal the two heat dissipation nets, preventing the marine transformer from being easily affected by external moisture, and ensuring the safety of the marine transformer during use.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all of the embodiments.

[0026] Reference Figure 1-Figure 7 A double-plate secondary flow-guiding marine leakage protection device is a leakage protection device specially used in a marine navigation environment, which specifically includes a box body 1 and a marine transformer 6. The marine transformer 6 is threadedly installed on the inner bottom surface of the box body 1 through a plurality of first bolts. A protection door 2 for protecting the marine transformer 6 is installed on the front of the box body 1. A protection mechanism for protecting the marine transformer 6 from leakage is installed inside the box body 1. The protection mechanism includes two movable plates 7. The two movable plates 7 are symmetrically arranged inside the box body 1. A through hole is opened at the center of the bottom of the box body 1. A threading tube 9 is installed inside the through hole. Wires 5 are installed on the outer walls of the two movable plates 7 that are close to each other. The ends of the two wires 5 away from the movable plates 7 pass through the threading tube 9 and contact the hull. The two movable plates 7 move towards each other and abut against both sides of the marine transformer 6. When the marine transformer 6 has leakage and its shell is charged, the two movable plates 7 contact its shell and are led into the ground with the help of the wire 5, so as to achieve the effect of quickly dealing with the leakage phenomenon of the marine transformer 6 and avoid harm to the staff who accidentally touch the marine transformer 6.

[0027] As a technical optimization solution in the utility model, two grooves 8 are symmetrically opened on the inner bottom surface of the box body 1, and screw rods 10 are rotatably installed inside the two grooves 8, and moving blocks 11 are installed on the outer walls of the two screw rods 10. Two first driving devices are preset inside the box body 1, and the output ends of the two first driving devices are respectively connected to one end of the two screw rods 10, so that the two screw rods 10 can be driven to rotate inside the corresponding grooves 8.

[0028] As a technical optimization solution in the utility model, the tops of the two moving blocks 11 are both rotatably installed with rotating blocks 17 through screws 18, one end of the two screws 18 passes through the moving blocks 11 and is threadedly installed with nuts, and the ends of the two rotating blocks 17 away from the moving blocks 11 are rotatably connected to the moving plate 7 close to them through the damping shaft 16. During the rotation process, the screw 10 can drive the moving block 11 to move back and forth inside the groove 8, thereby being able to drive the moving plate 7 and other components to move back and forth inside the box 1; the rotating block 17 is rotatably connected to the moving block 11 by means of the screw 18, and by tightening the nut, the position of the rotating block 17 inside the moving block 11 can be limited and fixed, thereby achieving the effect of limiting and fixing the moving plate 7; the rotating block 17 and the moving plate 7 are rotatably connected by means of the damping shaft 16, which is convenient for flexibly adjusting the rotation angle of the moving plate 7 itself.

[0029] As a technical optimization solution in the utility model, the outer walls of both sides of the box body 1 are installed with heat dissipation nets 3, and the outer walls of the box body 1 near the bottom of the two heat dissipation nets 3 are provided with inclined surfaces. The outer wall of the box body 1 near the bottom of the heat dissipation net 3 is provided with an inclined surface, so that when cleaning the debris inside the heat dissipation net 3, the debris falls down on the surface of the inclined surface and can slide down to the hull, avoiding accumulation at the bottom of the heat dissipation net 3.

[0030] As a technical optimization solution in the present invention, the outer walls of the two moving plates 7 on the side away from each other are both installed with rubber pads 15, and the outer walls of the two rubber pads 15 on the side away from the moving plates 7 are both installed with a plurality of protrusions 14 that match the meshes of the heat dissipation net 3. By arranging the rubber pads 15 on the outer walls of the two moving plates 7 on the side away from each other, the two moving plates 7 can be more closely in contact with the two heat dissipation nets 3 after moving in the direction away from each other, thereby improving the sealing effect of the heat dissipation net 3; and the protrusions 14 arranged on the outer walls of the rubber pads 15 can be inserted into the meshes inside the heat dissipation net 3, thereby further improving the blocking effect of the heat dissipation net 3, and can also take advantage of the situation to clean and remove the debris accumulated in the meshes inside the heat dissipation net 3.

[0031] As a technical optimization scheme in the utility model, the outer wall of the side where the two moving plates 7 are close to each other is provided with a rectangular groove 19, and the inside of the two rectangular grooves 19 is rotatably installed with a rotating plate 13, and the two rotating plates 13 and the moving plate 7 are made of conductive metal materials. The two rotating plates 13 are rotatably connected to the inner wall of the rectangular groove 19 through the electric rotating shafts set at both ends, and the second driving device is preset inside the two moving plates 7, and the output end of the second driving device is connected to one end of the electric rotating shaft, so that the rotating plate 13 can be driven to rotate and extend inside the rectangular groove 19; through the rotating plate 13, the two moving plates 7 can move in the direction away from each other to block the two heat dissipation nets 3, and the two rotating plates 13 can be controlled to rotate and extend from the corresponding rectangular groove 19, and the ends of the two rotating plates 13 away from the rectangular groove 19 are both in contact with the outer walls of the ship transformer 6 on both sides, which can maintain the effect of treating the leakage of the shell of the ship transformer 6. The ship transformer 6 is a special transformer used on existing ships, and its working principle is the same as that of the existing ship transformer.

[0032] As a technical optimization solution in the utility model, the tops of the two moving plates 7 are both threadedly installed with insulation monitors 12 through two second bolts 20. The two insulation monitors 12 are connected to the insulation resistance at the top of the marine transformer 6 through connecting wires. The insulation monitor 12 is an existing monitoring instrument, and its working process is the same as the working process of the existing insulation monitor. The top of the box 1 is equipped with an alarm 4 electrically connected to the insulation monitor 12. Through the set insulation monitor 12, the insulation of the insulation resistance at the top of the marine transformer 6 can be monitored in real time. When the insulation resistance is lower than the set value, the insulation monitor 12 will transmit a signal to the central controller, and the central controller will control the alarm 4 to sound an alarm, reminding relevant staff to maintain the insulation state of the marine transformer 6 in time to avoid failure of the marine transformer 6 in subsequent work. The working process of the mutual cooperation between the insulation monitor 12, the central controller and the alarm 4 is the same as the working process of the mutual cooperation between the existing insulation monitor, the controller and the alarm.

[0033] In the utility model, when the marine transformer 6 is installed inside the box body 1 for use, the two screw rods 10 can be controlled to rotate together, driving the two moving blocks 11 and the two moving plates 7 arranged above them to move together in the direction of approaching each other, until the two moving plates 7 are respectively in contact with the outer walls of the two sides of the marine transformer 6. If the marine transformer 6 has leakage, the leakage current located in the shell of the marine transformer 6 will be guided into the wire 5 with the help of the two moving plates 7, and the current will be introduced into the hull through the wire 5, triggering the grounding protector or leakage protector preset inside the box body 1 to start, thereby cutting off the power supply of the marine transformer 6, and protecting the safety of the marine transformer 6 itself and the personal safety of the staff who accidentally touch the marine transformer 6 due to the turbulence on the ship or other reasons.

[0034] By setting up the insulation monitor 12, the insulation resistance of the insulation resistance at the top of the marine transformer 6 can be monitored in real time. When the insulation resistance is lower than the set value, the insulation monitor 12 will transmit a signal to the central controller, and the central controller will control the alarm 4 to sound an alarm, reminding relevant staff to maintain the insulation status of the marine transformer 6 in time to avoid failure of the marine transformer 6 in subsequent work.

[0035] If the environment outside the box body 1 is relatively humid, in order to prevent the external moisture from entering the box body 1 through the two heat dissipation nets 3, causing the marine transformer 6 to be damp, the insulation resistance of the marine transformer 6 is reduced, and the marine transformer 6 is prone to leakage problems during use, such as Figure 6 As shown, the two screw rods 10 can be controlled to reverse together, driving the two movable plates 7 to move in directions away from each other, until the rubber pads 15 on the outer walls of the two movable plates 7 on the away side are tightly in contact with the inner walls of the two heat dissipation nets 3, thereby sealing the two heat dissipation nets 3, preventing the marine transformer 6 from being easily affected by external moisture, and ensuring the safety of the marine transformer 6 during use.

[0036] While the two movable plates 7 move in directions away from each other to block the two heat dissipation nets 3, the two rotating plates 13 are controlled to rotate and extend from the corresponding rectangular grooves 19, and the ends of the two rotating plates 13 away from the rectangular grooves 19 are in contact with the outer walls of both sides of the marine transformer 6, which can maintain the effect of the leakage treatment of the shell of the marine transformer 6; and the rubber pads 15 can be used to insulate the diverted current to prevent the current from being guided to the surface of the box body 1 to cause secondary damage, thereby improving the protection level of the leakage treatment on the hull and reducing the probability of leakage to a minimum.

[0037] And because the multiple protrusions 14 arranged on the outer wall of one side away from the two rubber pads 15 are adapted to the mesh holes inside the heat dissipation net 3, the protrusions 14 arranged on the outer wall of the rubber pad 15 are inserted into the mesh holes inside the heat dissipation net 3, on the one hand, the blocking effect of the heat dissipation net 3 can be further improved, and on the other hand, the sundries accumulated in the mesh holes inside the heat dissipation net 3 can be cleaned and removed, thereby improving the heat dissipation effect of the heat dissipation net 3 on the marine transformer 6 inside the box body 1.

[0038] If the staff needs to inspect the marine transformer 6, but the insulation resistance and other components on the top of the marine transformer 6 are in a higher position, it is not easy for the staff to directly inspect it. At this time, the two movable plates 7 can be driven to rotate one side of the rubber pad 15 to the back of the box body 1, and then the two nuts are unscrewed from the outer wall of the screw 18, and the two movable plates 7 are rotated downward so that the two movable plates 7 are both in contact with the inner bottom surface of the box body 1. At this time, after the rotating plates 13 inside the two rectangular grooves 19 are rotated downward to a vertical state, they can assist in supporting the horizontal movable plates 7. At this time, the staff can stand on the top of the horizontal movable plates 7 to quickly inspect multiple components on the top of the marine transformer 6, thereby improving the inspection efficiency of the marine transformer 6; and the rubber pads 15 and multiple protrusions 14 located on the top of the two movable plates 7 at this time can also increase the friction between the soles of the staff and the movable plates 7, so that the staff standing on the top of the movable plates 7 is more stable and more suitable for the inspection environment at sea.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
