For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0045] The following will, with reference to the drawings, elaborate on some embodiments of the present application. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] As described in the background art, in order to achieve the electrification of inland waterway shipping and realize the electric traction of ships, the applicant has proposed an electrified water transportation system. Please refer to Figure 1 , the electrified water transportation system includes a power supply vehicle, a ship, and a cable. Among them, the ship can navigate in the river channel, and tracks are laid along the river bank, and the power supply vehicle can move along the tracks.

[0047] In this power supply system, the power supply vehicle can supply power to the ship through a cable, and the power supply vehicle runs synchronously with the ship. Specifically, a power supply rail is arranged on the track. The power supply vehicle can draw power from the power supply rail and transmit the grid power to the ship through the cable, which is used as the motive power or self-use power of the ship, etc. At the same time, the moving direction and moving speed of the ship and the power supply vehicle are the same before, such as Figure 1 In the figure, both the ship and the power supply vehicle run along the arrow direction at the same speed, thus ensuring that the power supply vehicle supplies power to the ship in real time.

[0048] In practical applications, the length of the cable is generally selected to be of a moderate length. If the cable length is too short, it limits the ship to navigate only within a relatively short range along the riverbank, and the practicability is poor. If the cable length is too long, the cost is high, and it is inconvenient to store. And in practical applications, when the ship's heading deviates, or other environmental factors cause the ship to sail to the limit distance of the cable, there will be a tug-of-war on the cable between the ship and the power supply vehicle, which will cause the cable to be under greater stress and may ultimately lead to cable breakage or even track damage.

[0049] In view of this, the present application provides a power supply cable, which avoids excessive stress on the cable by setting an emergency release device on the power supply cable.

[0050] The following is an exemplary description of the power supply cable provided by the present application:

[0051] As an optional implementation manner, the power supply cable 100 is applied to an electrified water transportation system. The electrified water transportation system further includes a power supply vehicle and a ship, and the power supply vehicle runs synchronously with the ship. Please refer to Figure 2 In the figure, the power supply cable 100 includes a cable main body 110 and an emergency release device 120. The cable main body 110 is electrically connected to the power supply vehicle and the ship respectively, and the emergency release device 120 is installed on the cable main body 110. And the cable main body 110 is used to transmit the power of the power supply vehicle to the ship, and the emergency release device 120 is used to release when the tension borne by the cable main body 110 is greater than the threshold value to disconnect the connection between the cable main body 110 and the power supply vehicle or the ship.

[0052] Among them, when the power supply vehicle supplies power to the ship through the power supply cable 100, it can supply single-phase power to the ship or three-phase power to the ship, which is not limited here. For example, as Figure 3 shown, when single-phase power supply is adopted, the cable main body 110 includes a live wire, a neutral wire and an outer shell. The live wire and the neutral wire are both wrapped in their respective insulating layers, and at the same time the outer shell is wrapped outside the insulating layers of the live wire and the neutral wire, and the single-phase grid power is transmitted through the cable main body 110.

[0053] Or, as Figure 4As shown, when powered by three-phase electricity, the cable main body 110 includes three phase lines, namely the A-phase line, the B-phase line, and the C-phase line, as well as the neutral line and the outer shell. The neutral line and the three phase lines are all wrapped in their respective insulating layers, and at the same time, the outer shell is wrapped outside the insulating layers of the neutral line and the three phase lines. The transmission of three-phase power grid electricity is achieved through the cable main body 110.

[0054] Since an emergency release device 120 is provided on the cable main body 110, when the ship deviates from its course and sails away from the power supply vehicle, the tension on the cable main body 110 gradually increases. When the tension is greater than the threshold that the emergency release device 120 can withstand, the emergency release device 120 will loosen. At this time, the power supply vehicle and the ship cannot be connected by the cable, ensuring that the tension borne by the cable main body 110 will not be too large and avoiding the situation of the cable main body 110 breaking or the track along the river bank being damaged.

[0055] Among them, the present application does not limit the installation position of the emergency release device 120. For example, as Figure 2 shown, the emergency release device 120 can be installed at the end of the cable main body 110. Of course, it can also be installed at the middle position of the cable main body 110. At this time, both ends of the cable main body 110 are respectively connected to the ship and the power supply vehicle. When the tension borne by the cable main body 110 is greater than the threshold, the cable main body 110 will be divided into two at the emergency release device 120, avoiding accidents such as the cable main body 110 breaking. For the convenience of description, in the present application, the case where the emergency release device 120 is installed at the end of the cable main body 110 is taken as an example for description.

[0056] It can be understood that when the emergency release device 120 is loosened, if the ship resumes sailing on the established route and does not cause excessive stress on the cable main body 110, the cable main body 110 can be reconnected to ensure that the power supply vehicle continues to supply power to the ship.

[0057] It should be noted that the present application does not limit the specific value of the threshold, as long as the threshold is less than the stress corresponding to the breakage of the cable main body 110. Of course, setting too small a threshold is likely to cause the emergency release device 120 to loosen frequently, resulting in poor practicability. Therefore, an appropriate threshold can be selected according to the actual working conditions.

[0058] Among them, when the emergency release device 120 is installed at the end of the cable main body 110, the cable main body 110 is connected to a power supply vehicle or a ship through the emergency release device 120. It can be understood that when one end with the emergency release device 120 installed is connected to the ship, the other end of the power supply cable 100 is connected to the power supply vehicle. At this time, when the emergency release device 120 is released, it means that the power supply cable 100 is disconnected from the ship; when one end with the emergency release device 120 installed is connected to the power supply, the other end of the power supply cable 100 is connected to the ship. At this time, when the emergency release device 120 is released, it means that the power supply cable 100 is disconnected from the power supply vehicle.

[0059] The following will explain the two situations separately:

[0060] When one end with the emergency release device 120 installed is connected to the ship, there is a socket hole on the ship. Inside the socket hole, there are a power receiving terminal and a clamping part. The cable main body 110 is plugged into the ship through the socket hole. When the cable main body 110 is plugged into the ship, the cable main body 110 is electrically connected to the power receiving terminal, and the emergency release device 120 is clamped with the clamping part. And when the tension borne by the cable main body 110 is greater than the threshold value, the emergency release device 120 is disengaged from the clamping part.

[0061] Among them, the present application does not limit the specific structure of the emergency release device 120. It only needs that when the cable main body 110 is plugged into the ship, the emergency release device 120 can be clamped with the clamping part on the ship to ensure their stable connection. At the same time, when the force received is too large, the emergency release device 120 can be disengaged from the clamping part.

[0062] Such as Figure 2 shown, the present application provides an exemplary structure of the emergency release device 120. The emergency release device 120 can be set as an elastic protrusion. The structure of the protrusion can be not limited. For example, it can be a triangular pyramid-shaped protrusion, or an arc-shaped protrusion, etc. And for the number of protrusions, the present application also does not limit it. For example, as Figure 2 described, the number of protrusions can be set to 2. Of course, it can also be set to 1, or set to 4, or directly set a circle of protrusions around the end of the power supply cable 100.

[0063] And, the protrusion has elasticity. Exemplarily, a spring is arranged at the bottom of the protrusion, so that in the normal state, it presents the structure as Figure 2 described. When the protrusion is pressed, the protrusion can be along Figure 2Move in the direction indicated by the arrow. On this basis, the clamping part provided on the ship can be a groove corresponding to the convex structure. For example, when the convex is a triangular pyramid structure, the clamping part is set as a triangular pyramid groove of the same size. When the cable body 110 is plugged into the ship, due to the function of the plugging hole, the convex structure will be pressed down and continuously pushed forward along the insertion hole until the convex moves to the groove position in the plugging hole. Due to the elastic effect, the convex is bounced up and located in the groove, realizing the clamping and fixing of the two. When the power supply cable 100 is under tension, it is actually a force to pull the cable body 110 outwards. If the tension is too large, the convex is pressed down again until it is pulled out of the plugging hole.

[0064] On the basis of this setting method, the tension threshold of the cable body 110 can be set by the height of the convex and the elastic force of the spring at the bottom of the convex. For example, the higher the convex height, the larger the threshold; the greater the elastic force of the spring at the bottom of the convex, the larger the threshold.

[0065] When one end of the emergency release device 120 is connected to the ship, since the ship is sailing on the water surface, if the plugging hole of the emergency release device 120 is disengaged from the ship at this time, the cable body 110 will fall into the water due to gravity. At this time, since the cable body 110 is connected to the power supply vehicle, it may cause a short circuit of the entire power supply vehicle and even a short circuit of the entire power grid.

[0066] Therefore, in one implementation, please refer to Figure 5 , the power supply cable 100 further includes a waterproof cover, which is rotatably connected to the end of the cable body 110, and a receiving space is provided at the end of the cable body 110; when the cable body 110 is not plugged into the ship, the waterproof cover is in a normally closed state to cover the end of the cable body 110; when the cable body 110 is plugged into the ship, the waterproof cover rotates into the receiving space.

[0067] Among them, components such as a sealing ring can be provided on the waterproof cover, so that when it is in the normally closed state, it can be sealed to prevent water from entering the receiving space and avoid the occurrence of a short circuit of the cable body 110. As Figure 5 shown, the waterproof cover can rotate along the direction of the dotted double arrow, and when the waterproof cover is in the normally closed state, the waterproof cover is in position A; when the waterproof cover rotates into the receiving space, the waterproof cover can be in position B. And the waterproof cover can be rotatably connected to the end of the cable body 110 through an elastic member, so that it is always in the normally closed state. Only when it receives a thrust towards the receiving space, the waterproof cover will rotate towards the receiving space. Once the thrust towards the receiving space disappears, the waterproof cover returns to position A and is in the normally closed state.

[0068] And at the end of the accommodation space, when single-phase power supply is adopted, the cable body 110 is arranged in the form of live wire and neutral wire terminals; when three-phase power supply is adopted, the cable body 110 is arranged in the form of A, B, and C three-phase terminals. On this basis, please refer to Figure 6 , which is a schematic structural diagram of a single-phase power supply socket hole provided on a ship. A power receiving terminal and a clamping portion (the groove in the figure) are provided in the socket hole. The power receiving terminal includes a live wire power receiving terminal and a neutral wire power receiving terminal. When three-phase power supply is adopted, the power receiving terminal includes A, B, and C three-phase power receiving terminals. The A, B, and C three-phase power receiving terminals are relatively long, and there is no other filler around the A, B, and C three phases. When the cable body 110 is inserted into the socket hole, the cable body 110 is located in the socket hole, and the A, B, and C three-phase power receiving terminals push the waterproof cover to rotate towards the accommodation space until the A-phase power receiving terminal is connected to the A-phase terminal of the cable body 110, the B-phase power receiving terminal is connected to the B-phase terminal of the cable body 110, and the C-phase power receiving terminal is connected to the C-phase terminal of the cable body 110.

[0069] When one end of the emergency release device 120 is connected to the power supply vehicle, a socket hole is provided on the power supply vehicle. A power supply terminal and a clamping portion are provided in the socket hole. The cable body 110 is inserted into the power supply vehicle through the socket hole; when the cable body 110 is inserted into the power supply vehicle, the cable body 110 is electrically connected to the power supply terminal, and the emergency release device 120 is clamped with the clamping portion, and when the tension borne by the cable body 110 is greater than the threshold value, the emergency release device 120 is disengaged from the clamping portion.

[0070] The principle of the connection between the emergency release device 120 and the power supply vehicle is the same as the connection principle between the emergency release device 120 and the ship described above, and will not be elaborated here. It should be noted that when the emergency release device 120 is connected to the power supply vehicle, then after the emergency release device 120 is disengaged from the power supply vehicle, the cable body 110 is actually not energized. Therefore, at this time, a waterproof cover may not be provided at the end of the cable body 110.

[0071] In addition, in order to achieve synchronous operation between the power supply vehicle and the ship, the power supply vehicle and the ship are communicatively connected, and the ship sends information such as its operating speed to the power supply vehicle so that the power supply vehicle can adjust its own speed in real time to achieve the effect of the vehicle following the ship.

[0072] On this basis, the power supply vehicle and the ship can communicate by wire or by wireless. When communicating by wire, the power supply cable 100 further includes a communication cable. The communication cable is laid together with the cable body 110. The communication cable is communicatively connected to the power supply vehicle and the ship respectively, and the power supply vehicle and the ship communicate through the communication cable. The emergency release device 120 is installed on the cable body 110 and the communication cable. Therefore, when the emergency release device 120 is disengaged, the power supply vehicle stops supplying power to the ship and disconnects the communication at the same time.

[0073] Based on the above implementation, an embodiment of the present application further provides a power supply component, which is applied to an electrified water transportation system. The power supply component includes a clamping device and the above-mentioned power supply cable 100. The clamping device is installed on a power supply vehicle or a ship; when the power supply cable 100 is connected to the clamping device, the emergency release device 120 is clamped with the clamping device, and when the tension borne by the cable body 110 is greater than a threshold value, the emergency release device 120 is separated from the clamping device.

[0074] Among them, the structure of the clamping device can be similar to the structure of the above-mentioned insertion hole, which is not limited herein. By setting the clamping device, the line on the ship or the power supply vehicle can be directly connected to the clamping device, and there is no need to set an insertion hole, which makes the connection more convenient.

[0075] As an implementation, the power supply component further includes a traction device. The traction device is installed on a power supply vehicle, a ship or the clamping device. When the traction device is installed on a power supply vehicle or a ship, the traction device and the clamping device are installed in the same area, and the traction device is connected to the cable body 110; when the emergency release device 120 is separated from the clamping device, the traction device remains connected to the cable body 110.

[0076] Among them, the traction device can be a traction rope. After the emergency release device 120 is separated, the cable body 110 can still be connected by the traction rope. When the ship's route is corrected, the cable body 110 can be pulled back to the original position by the traction rope, and the user only needs to insert the cable body 110 into the clamping device, which is more convenient to use.

[0077] In one implementation, when the power supply cable 100 further includes a communication cable, the traction device includes a traction communication cable. One end of the traction communication cable is connected to the communication cable in the power supply cable 100, and the other end is connected to a power supply vehicle or a ship; among them, when the emergency release device 120 is separated from the clamping device, communication is maintained between the power supply vehicle and the ship through the communication cable and the traction communication cable in the power supply cable 100.

[0078] Among them, using the communication cable as the traction device enables the power supply vehicle to still obtain information such as the propagation rate of the ship through the communication cable after the emergency release device 120 is separated, thereby realizing synchronous operation.

[0079] Based on the above implementation, an embodiment of the present application further provides an electrified water transportation system. The electrified water transportation system includes a power supply vehicle, a ship, and the above-mentioned power supply cable 100. The power supply cable 100 is electrically connected to the power supply vehicle and the ship respectively; the power supply vehicle is used to deliver power to the ship through the cable body 110, and when the tension borne by the cable body 110 is greater than a threshold value, the emergency release device 120 in the power supply cable 100 is loosened.

[0080] As an implementation, the electrified water transportation system further includes a storage box, which is installed on the power supply vehicle or the ship. Part or all of the power supply cable 100 is wound in the storage box, and the storage box is used to wind and unwind the power supply cable 100. For example, the storage box can be set as a rolling shutter storage box to wind and unwind the power supply cable 100. When the distance between the ship and the power supply vehicle is relatively close, the rolling shutter storage box automatically stores the excess cable; when the distance between the ship and the power supply vehicle is relatively far, the rolling shutter storage box automatically releases the excess cable.

[0081] In summary, the present application provides a power supply cable, a power supply component, and an electrified water transportation system. The electrified water transportation system includes a power supply vehicle and a ship, and the power supply vehicle and the ship operate synchronously. The power supply cable includes a cable main body and an emergency release device. The cable main body is electrically connected to the power supply vehicle and the ship respectively, and the emergency release device is installed on the cable main body.
