[0035] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0036] As Figure 1-8 shown, a copper switch with high sealing performance includes:

[0037] A sealed switch bladder 1, inside which there is a connecting seat 12;

[0038] An isolated power connection mechanism 2, which includes a rotating sleeve 21 movably arranged on the sealed switch bladder 1 and a fixed connection post 22 slidably connected inside the rotating sleeve 21, and the rotating sleeve 21 is driven to be movably electrically connected to the connecting seat 12;

[0039] A cable 3, which is arranged at the end of the fixed connection post 22 and electrically connected to the rotating sleeve 21.

[0040] Specifically, the end of the fixed connection post 22 (taking Figure 4For reference, power connection blocks 24 are symmetrically arranged at the ends (the ends are the lower ends), and an installation pipe groove 222 is formed in the fixed connection post 22. The installation pipe groove 222 is aligned with the power connection block 24. A locking screw 241 is threadedly connected to the power connection block 24. During installation, the end of the cable 3 is cut to expose the copper core 31. After passing the copper core 31 through the power connection block 24, the locking screw 241 is rotated to squeeze and lock the copper core 31, and the remaining cable 3 is clamped into the installation pipe groove 222 to complete the installation of the cable 3. A fixed cover 10 is arranged inside the sealed switch housing 1, and the connection seat 12 is arranged inside the fixed cover 10. When the connection seat 12 contacts the rotating sleeve 21, the two power connection blocks 24 are energized to close the circuit. Before use, first pull out the fixed connection post 22 from the rotating sleeve 21, then install the cable 3 on the fixed connection post 22, and then insert the fixed connection post 22 along the rotating sleeve 21 and lock it to electrically connect the rotating sleeve 21 and the cable 3 to complete the installation.

[0041] In the above technical solution, the cable 3 is connected to be arranged inside the rotating sleeve 21 through the fixed connection post 22, and then the rotating sleeve 21 is driven to switch the circuit. The rotating sleeve 21 bears the electrical connection between the cable 3 and the internal energized parts, so as to avoid opening and closing the whole during the installation process, and avoid the situation that the internal energized parts have gaps due to the installation of the cable 3, which can enhance the internal sealing ability.

[0042] Further, the structure for locking the fixed connection post 22 in the rotating sleeve 21 can be magnetic rings respectively arranged on the fixed connection post 22 and the rotating sleeve 21, and the two magnetic rings are magnetically connected to lock and fix; it can also be a buckle arranged on the fixed connection post 22 and a snap ring arranged on the rotating sleeve 21, and the fixed connection post 22 and the rotating sleeve 21 are locked by the snap ring and the buckle.

[0043] As the optimal embodiment provided by the present invention, a sealing airbag 23 is arranged between the fixed connection post 22 and the rotating sleeve 21. The sealing airbag 23 is driven to expand to seal the gap between the fixed connection post 22 and the rotating sleeve 21 and make them move towards each other;

[0044] Connecting blocks 210 are symmetrically arranged on the rotating sleeve 21, and a limiting groove 221 is formed in the fixed connection post 22. The sealing airbag 23 is driven to expand along the limiting groove 221 to push the fixed connection post 22 to fit against the connecting block 210.

[0045] Specifically, the rotating sleeve 21 is provided with a ventilation port 211. The air inlet and outlet of the plugging airbag 23 is located in the ventilation port 211. The plugging airbag 23 is fixedly connected to the inner wall of the rotating sleeve 21, and the plugging airbag 23 has an outward convex contour corresponding to the limiting groove 221. When the fixed connection post 22 is slid along the rotating sleeve 21, the power connection block 24 will be slid into the groove opened on the connection block 210 to dock the power connection block 24 and the connection block 210. Then, through the inflation unit (the inflation unit can be a manual air pump, or a bicycle pump, etc.), the ventilation port 211 inflates the plugging airbag 23, so that the plugging airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed connection post 22, achieving a sealing effect and reducing the entry of water vapor. Then, the expanded outward convex contour pushes against the limiting groove 221, so that the rotating sleeve 21 and the fixed connection post 22 move towards each other to play a locking role, without the need for additional metal fasteners for locking and fixing, avoiding the corrosion of metal fasteners by the humid water vapor on the sea surface.

[0046] Before use, first pull out the fixed connection post 22 from the rotating sleeve 21, then install the cable 3 on the fixed connection post 22, and then insert the fixed connection post 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove opened on the connection block 210 for docking, to electrically connect the rotating sleeve 21 and the cable 3. Then, inflate the plugging airbag 23 with gas. The plugging airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed connection post 22, and pushes the rotating sleeve 21 and the fixed connection post 22 to move towards each other and lock.

[0047] As an embodiment provided by the present invention, the plugging airbag 23 is symmetrically provided with abrasive plates 232. The abrasive plates 232 reciprocally grind along the docking end of the connection block 210 as the plugging airbag 23 expands and contracts.

[0048] Specifically, a part of the plugging airbag 23 extends into the sealed switch chamber 1, and a part of it is symmetrically provided with abrasive plates 232. The abrasive plates 232 correspond to the docking end of the connection block 210 ( Figure 8 for reference, the docking end of the connection block 210 is the lower end). On the deck of the ship, due to the strong sunlight irradiation on the sea surface, the temperature difference between day and night on the deck (the temperature difference can reach up to 20 °C) is large, which will cause the gas (a gas with a large expansion coefficient: such as carbon dioxide) in the plugging airbag 23 to expand and contract, so as to drive the abrasive plates 232 to rub off the copper rust corroded on the docking end of the connection block 210 due to water vapor as they expand and contract, so as to extend the service life of the connection block 210, avoid failure when the closed circuit needs to be suddenly stopped, and cope with the situation of accelerated rusting caused by water vapor and sodium chloride in the sea breeze.

[0049] Before use, first pull out the fixed terminal 22 from the rotating sleeve 21, then install the cable 3 on the fixed terminal 22, and then insert the fixed terminal 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove opened on the connection block 210 for docking, so as to electrically connect the rotating sleeve 21 and the cable 3. Then, when the temperature is relatively low, inflate the sealing airbag 23. The sealing airbag 23 expands initially to fill the gap between the rotating sleeve 21 and the fixed terminal 22, and pushes the rotating sleeve 21 and the fixed terminal 22 to move towards each other and lock. When the ambient temperature rises sharply, the sealing airbag 23 expands again to drive the abrasive plate 232 to rub along the docking end of the connection block 210, and contracts when the temperature drops, and rubs again to grind off the surface copper rust.

[0050] As a further embodiment provided by the present invention, a guiding deformation cover 26 is sleeved on the rotating sleeve 21, and an extension end 231 extending into the guiding deformation cover 26 is arranged on the sealing airbag 23. The rotating sleeve 21 is driven to move so that the extension end 231 slides into the deformed guiding deformation cover 26.

[0051] Specifically, the guiding deformation cover 26 is arranged between the rotating sleeve 21 and the connection seat 12. The extension end 231 fits against the inner wall of the guiding deformation cover 26 and is fixedly communicated with the sealing airbag 23. The wall thickness of the extension end 231 is smaller than that of the sealing airbag 23, and it will expand or contract first when the temperature difference changes. When the rotating sleeve 21 moves along the sealed switch bladder 1 to dock with the connection seat 12, the guiding deformation cover 26 is squeezed and deformed to form a receiving space, and then the extension end 231 will enter along the receiving space to provide a flipping space for the abrasive plate 232, avoiding the abrasive plate 232 from hindering the normal opening and closing of the rotating sleeve 21. A guiding inclined surface 121 is opened on the connection seat 12 to guide. The extension end 231 of the sealing airbag 23 slides into the receiving space along the guiding inclined surface 121 to avoid hindering the docking of the rotating sleeve 21 and the connection seat 12.

[0052] Before use, first pull out the fixed terminal 22 from the rotating sleeve 21, then install the cable 3 on the fixed terminal 22, and then insert the fixed terminal 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove opened on the connection block 210 for docking, so as to electrically connect the rotating sleeve 21 and the cable 3. Then, inflate the sealing airbag 23. The sealing airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed terminal 22, and pushes the rotating sleeve 21 and the fixed terminal 22 to move towards each other and lock. When the ambient temperature changes sharply, the sealing airbag 23 contracts to drive the abrasive plate 232 to reciprocally rub along the docking end of the connection block 210 to grind off the surface copper rust. When the circuit needs to be closed, press the rotating sleeve 21 so that the guiding deformation cover 26 is squeezed to provide a flipping space for the abrasive plate 232.

[0053] As the optimal embodiment provided by the present invention, it further includes a frosted plate 232 disposed on the extension end 231. A deformation groove 263 is formed in the guiding deformation cover 26. As the rotating sleeve 21 moves, the deformation groove 263 deforms along the deformation groove 263 to accommodate a part of the extension end 231 and flip the frosted plate 232.

[0054] Specifically, a first deformation plate 261 and a second deformation plate 262 are symmetrically arranged at both ends of the deformation groove 263. The first deformation plate 261 and the second deformation plate 262 are attached to the extension end 231 for support to prevent the extension end 231 from expanding and contracting due to temperature difference changes and squeezing into the storage space, ensuring the normal use of the frosted plate 232. The deformation groove 263 is formed in the storage space. When the guiding deformation cover 26 is squeezed, it will bend along the deformation groove 263 to expand the storage space. While bending, the first deformation plate 261 and the second deformation plate 262 flip and fit along the storage space, losing the support ability for the extension end 231, and can protect the elastic deformation groove 263 when the frosted plate 232 is pushed by the rotating sleeve 21 and flipped into the storage space.

[0055] Before use, first pull out the fixed connection post 22 from the rotating sleeve 21, then install the cable 3 on the fixed connection post 22, and then insert the fixed connection post 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove formed in the connection block 210 for docking, to electrically connect the rotating sleeve 21 and the cable 3. Then, inflate the sealing airbag 23. The sealing airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed connection post 22, and pushes the rotating sleeve 21 and the fixed connection post 22 to move towards each other and lock. When the environmental temperature changes drastically, the sealing airbag 23 contracts to drive the frosted plate 232 to reciprocally rub along the docking end of the connection block 210 to grind off the surface copper rust. When the circuit needs to be closed, press the rotating sleeve 21 so that the guiding deformation cover 26 is squeezed and bent along the deformation groove 263, and loses the support for the extension end 231, so that the frosted plate 232 flips with the deformation of the extension end 231.

[0056] As an embodiment provided by the present invention, the rotating sleeve 21 includes the following two working positions:

[0057] The first working position: The rotating sleeve 21 slides along the sealed switch cylinder 1 and fits with the connection seat 12 for power connection;

[0058] The second working position: The rotating sleeve 21 rotates to disconnect from the connection seat 12 and slides out of the sealed switch cylinder 1.

[0059] Specifically, an elastic cover 11 is provided between the sealed switch bladder 1 and the rotating sleeve 21, and a sealing cover 13 is provided between the sealed switch bladder 1 and the fixed cover 10. The elastic cover 11 and the sealing cover 13 are clamped to form an independent space, and the connecting seat 12 is arranged in the independent space to enhance the sealing ability of the sealed switch bladder 1, reduce the corrosion rate of copper energized parts, and extend the service life. Straight slots 111 are arranged in a circumferential array on the elastic cover 11, and the straight slots 111 can facilitate the deformation of the elastic cover 11 as the rotating sleeve 21 rotates. A power connection plate 122 is arranged on the connecting seat 12, and the power connection plate 122 contacts two connecting blocks 210 to close the circuit. An annular groove is also formed on the connecting seat 12 to guide the rotation of the rotating sleeve 21. The rotating sleeve 21 has the following two working positions to control the opening or closing of the circuit:

[0060] The first working position: The rotating sleeve 21 slides along the sealed switch bladder 1 and fits with the connecting seat 12, so that the power connection plate 122 contacts two connecting blocks 210 to connect two cables 3 for closing;

[0061] The second working position: Rotate the rotating sleeve 21 so that the connecting block 210 rotates along the annular groove away from the power connection plate 122. At this time, the circuit is opened, and the two cables 3 are disconnected. At the same time, the rotating sleeve 21 is driven away from the power connection plate 122 and rotates to reset, so that the connecting block 210 corresponds to the power connection plate 122, facilitating the short-circuit closing next time. The cable 3 can be connected to the circuit that needs to be emergently stopped on the ship deck, facilitating quickly pressing to connect the circuit to cut off certain equipment or put it in the emergency stop mode (the same function as the safety emergency stop switch) when needed.

[0062] Before use, first pull out the fixed terminal 22 from the rotating sleeve 21, then install the cable 3 on the fixed terminal 22, and then insert the fixed terminal 22 along the rotating sleeve 21 so that the contact block 24 slides into the groove formed on the connecting block 210 for docking to electrically connect the rotating sleeve 21 and the cable 3. Then, inflate the sealing airbag 23. The sealing airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed terminal 22, and pushes the rotating sleeve 21 and the fixed terminal 22 to move towards each other and lock. When the environmental temperature changes violently, the sealing airbag 23 contracts to drive the abrasive plate 232 to reciprocally rub along the docking end of the connecting block 210 to grind off the surface copper rust. When the circuit needs to be closed, press the rotating sleeve 21 so that the guiding deformation cover 26 is squeezed and bent along the deformation groove 263 and loses the support for the extending end 231, so that the abrasive plate 232 flips with the deformation of the extending end 231. At the same time, the rotating sleeve 21 slides along the sealed switch bladder 1 and fits with the connecting seat 12 to switch to the first working position. When the circuit needs to be disconnected, rotate the rotating sleeve 21 so that the connecting block 210 rotates along the annular groove away from the power connection plate 122 and reset the rotating sleeve 21 to the second working position.

[0063] As an embodiment further provided by the present invention, a limiting ring plate 212 is provided on the rotating sleeve 21, and a blocking elastic capsule 41 is provided in the sealed switch chamber 1. The blocking elastic capsule 41 is moved and squeezed by the limiting ring plate 212 to limit the rotating sleeve 21 to be located at one of the two working positions;

[0064] The blocking elastic bag 41 includes a first tension portion and a second tension portion, and the first tension portion and the second tension portion are symmetrically arranged along the limiting ring plate 212 .

[0065] Specifically, the sealing cover 13 is rotatably connected with a sliding ring 131, and the blocking elastic bag 41 is arranged on the sliding ring 131, so that the blocking elastic bag 41 is driven to rotate when the rotating sleeve 21 rotates, and the first tension part and the second tension part are respectively arranged at two ends of the blocking elastic bag 41 (with Figure 7 For reference, the first tension part is the lower end, the second tension part is the upper end, the elasticity of the first tension part is greater than that of the second tension part), and they are symmetrically arranged along the limiting ring plate 212. A buckle ring 213 is arranged on the limiting ring plate 212. The buckle ring 213 is an inclined surface, which can squeeze the first tension part to make it completely shrink. When the rotating sleeve 21 is located in the final position of the second station (that is, the connection block 210 corresponds to and is away from the power connection plate 122), the expansion ratio of the first tension part of the blocking elastic bag 41 is greater than the second tension part, so as to maintain the final position of the second station in the rotating sleeve 21. When the rotating sleeve 21 is switched to the first station and pressed down, the air in the first tension part will be pushed into the second tension part by the limiting ring plate 212 to expand it, and then the first tension part will be squeezed and contracted by the buckle ring 213. At this time, the downward pressure is released, but the first tension part needs a greater force to expand again after shrinking, so that the contracted state of the first tension part is fixed to maintain the rotating sleeve 21 to the first station. The push lock achieved by metal parts is changed to airbag lock, and can maintain the normally open and normally closed effects, which can avoid the accelerated aging of metal parts due to sea breeze corrosion. The sealing elastic bag 41 is filled with non-conductive liquid to reduce thermal expansion and contraction while avoiding leakage and conduction.

[0066] Before use, first pull out the fixed terminal 22 from the rotating sleeve 21, then install the cable 3 on the fixed terminal 22, and then insert the fixed terminal 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove opened on the connection block 210 for docking, so as to electrically connect the rotating sleeve 21 and the cable 3. Then, inflate the sealing airbag 23. The sealing airbag 23 expands to fill the gap between the rotating sleeve 21 and the fixed terminal 22, and pushes the rotating sleeve 21 and the fixed terminal 22 to move towards each other and lock. When the environmental temperature changes violently, the sealing airbag 23 shrinks to drive the abrasive plate 232 to reciprocally rub along the docking end of the connection block 210 to grind off the surface copper rust. When the circuit needs to be closed, press the rotating sleeve 21 so that the guiding deformation cover 26 is squeezed and bent along the deformation groove 263 and loses the support for the extension end 231, so that the abrasive plate 232 flips with the deformation of the extension end 231. At the same time, the rotating sleeve 21 slides along the sealing switch bladder 1 and fits with the connecting seat 12. At this time, the air in the first tension part will be pushed by the limiting ring plate 212 into the second tension part to make it expand, and switch to the first working position. When the circuit needs to be disconnected, rotate the rotating sleeve 21 so that the connection block 210 rotates along the annular groove away from the connection plate 122, and reset the rotating sleeve 21 to the second working position.

[0067] As the optimal embodiment provided by the present invention, a communicating bladder 42 is arranged in the sealing switch bladder 1. The communicating bladder 42 is fixedly communicated with the first tension part and the second tension part through the first telescopic tube 43 and the second telescopic tube 411 respectively, and is assembled in the following two working positions:

[0068] The third working position: the second telescopic tube 411 stretches to cut off the communication ability, so that the sealing elastic bladder 41 closes, and the first telescopic tube 43 shrinks for one-way communication;

[0069] The fourth working position: the second telescopic tube 411 shrinks for communication to input the liquid in the sealing elastic bladder 41 into the communicating bladder 42, and the first telescopic tube 43 stretches to close.

[0070] Specifically, a fixed connecting pipe 44 is provided on the sealing cover 13. The second telescopic pipe 411 is fixedly connected to the fixed connecting pipe 44, and the fixed connecting pipe 44 is fixedly connected to the connecting bladder 42. Only one of the first telescopic pipe 43 and the second telescopic pipe 411 is in a connected state at the same time. Check valves are provided in both the first telescopic pipe 43 and the second telescopic pipe 411 to control the unidirectional flow of air. When the rotating sleeve 21 is in the final position of the second working position, the second telescopic pipe 411 is stretched to cut off the connection ability, which is the third working position, and the plugging elastic bladder 41 closes. Then, when the rotating sleeve 21 switches from the end of the second working position to the first working position, the second telescopic pipe 411 still cuts off the connection ability. When the rotating sleeve 21 rotates, the first telescopic pipe 43 and the second telescopic pipe 411 switch to the fourth working position. At this time, the second telescopic pipe 411 will contract and connect, and the liquid in the plugging elastic bladder 41 (i.e., the expanded second tension part) will be discharged into the connecting bladder 42 along the fixed connecting pipe 44. Then, release the rotating sleeve 21, and the elastic cover 11 and the guiding deformation cover 26 will rebound, so that the rotating sleeve 21 moves away from the connecting seat 12 by a small amount (5 mm to 15 mm) to keep the circuit disconnected. Then, the rotating sleeve 21 resets to switch the first telescopic pipe 43 and the second telescopic pipe 411 back to the third working position. At this time, the liquid flowing into the connecting bladder 42 is squeezed into the plugging elastic bladder 41 through the first telescopic pipe 43, so that it returns to the expanded state where the first tension part is greater than the second tension part.

[0071] Before use, first pull out the fixed connection post 22 from the rotating sleeve 21, then install the cable 3 on the fixed connection post 22, and then insert the fixed connection post 22 along the rotating sleeve 21 so that the power connection block 24 slides into the groove opened on the connection block 210 for docking, so as to electrically connect the rotating sleeve 21 and the cable 3. Then, when the temperature is relatively low, fill the plugging air bladder 23 with gas. The plugging air bladder 23 expands initially to fill the gap between the rotating sleeve 21 and the fixed connection post 22, and pushes the rotating sleeve 21 and the fixed connection post 22 to move towards each other and lock. When the ambient temperature rises sharply, the plugging air bladder 23 expands again to drive the abrasive plate 232 to rub along the docking end of the connection block 210. When the temperature drops, it contracts and rubs again to grind off the surface copper rust. When the circuit needs to be closed, press the rotating sleeve 21 so that the guiding deformation cover 26 is squeezed and bent along the deformation groove 263 and loses the support for the extending end 231, so that the abrasive plate 232 flips with the deformation of the extending end 231. At the same time, the rotating sleeve 21 slides along the sealing switch bladder 1 and fits with the connecting seat 12. At this time, the air in the first tension part will be pushed by the limiting ring plate 212 into the second tension part to make it expand, and switch to the first working position. When the circuit needs to be disconnected, rotate the rotating sleeve 21 so that the connection block 210 rotates along the annular groove away from the power connection plate 122. At the same time, the first telescopic pipe 43 and the second telescopic pipe 411 switch to the fourth working position, so that the plugging elastic bladder 41 contracts. Then, through the rebound and reset of the elastic cover 11 and the guiding deformation cover 26, the plugging elastic bladder 41 expands again, and the rotating sleeve 21 is reset to the second working position.
