Example 1: referring to fig. 1 to 5, the rotary joint for hybrid composite cables of the present embodiment includes a stationary end engagement mechanism 1000 and a movable end engagement mechanism 2000 coaxially connected in series, and the stationary end engagement mechanism 1000 and the movable end engagement mechanism 2000 are rotatably connected, so that they can rotate relatively along their central axes. The static end engagement mechanism 1000 and the moving end engagement mechanism 2000 may be connected by a common quick connector to achieve rotational connection, and the specific structure will not be described herein.
The stationary end engagement mechanism 1000 is provided with a first fluid conveying channel 1100 located at the center thereof and extending along the axis thereof, the movable end engagement mechanism 2000 is also provided with a second fluid conveying channel 2100 located at the center thereof and extending along the axis thereof, and the first fluid conveying channel 1100 is in rotary sealing connection with the second fluid channel 2100, so that the first fluid conveying channel 1100 and the second fluid channel 2100 remain in communication when the stationary end engagement mechanism 1000 and the movable end engagement mechanism 2000 relatively rotate, and the side wall of the stationary end engagement mechanism 1000 is provided with an input connector 1110 for inputting fluid, such as liquid and gas, to the first fluid conveying channel 1100. The form of the rotary seal connection between the first fluid delivery passageway 1100 and the second fluid passageway 2100 may be selected based on the seal pressure level, such as selecting a socket connection, inserting one end of the second fluid passageway 2100 into the first fluid delivery passageway 1100, and providing a seal in the annular cavity between the first fluid delivery passageway 1100 and the second fluid passageway 2100, such as selecting a mechanical seal connection.
The rotary joint also needs to transmit electric energy or electric signals, and the medium needs to be transmitted through conductive objects such as wires, so that the static end connecting mechanism 1000 is provided with at least two first wires 1200, the specific number is determined according to the number and the type of the transmission medium, for example, three first wires 1200 need to be arranged when three-phase electricity is transmitted. The movable end connection mechanism 2000 is provided with second wires 2200 the number of which is equal to that of the first wires 1200, each second wire 2200 is correspondingly connected with a circular conducting ring 2210, the conducting rings 2210 are spaced at a certain distance, and the circle centers of the conducting rings 2210 are coincident with the central axis of the movable end connection mechanism 2000; each first conductive wire 1200 is slidably and electrically connected to one conductive ring 2210. Because the center of each conductive ring 2210 coincides with the central axis of the moving end connection mechanism 2000, in the relative rotation process of the static end connection mechanism 1000 and the moving end connection mechanism 2000, the first conductive wire 1200 will rotate around the central axis of the moving end connection mechanism 2000, and in the rotation process, the first conductive wire 1200 is always in contact with the conductive ring 2210 and keeps electrical connection, the rotation angle is not limited, and 360 ° rotation can be realized.
In this embodiment, there are various ways of sliding and electrically connecting the first wire 1200 and the conductive ring 2210, as shown in fig. 5, the end of the first wire 1200 is connected with a spring clip 1210, a guide hole 1220 is disposed at one end of the stationary end connection mechanism 1000 opposite to the moving end connection mechanism 2000, a movable guide rod 1230 is disposed in the guide hole 1220, one end of the guide rod 1230 is inserted into the spring clip 1210 and is slidingly connected with the spring clip 1210, and meanwhile, a first spring 1240 is disposed for pushing the other end of the guide rod 1230 to move towards the moving end connection mechanism 2000 so as to compress the conductive ring 2210 for electrical connection.
Example 2: in embodiment 1, one end of the guide rod 1230 is in sliding contact with the conductive ring 2210, so that there is a larger abrasion, which affects the service life of the device, and the structure of the sliding electrical connection between the first wire 1200 and the conductive ring 2210 in embodiment 1 is improved to reduce the abrasion.
Referring to fig. 6, fig. 6 is a schematic structural diagram of sliding electrical connection between the first wires and the conductive rings in the present embodiment, the rotary connector for hybrid composite cable further includes a sliding electrical connection mechanism 3000, the sliding electrical connection mechanism 3000 includes a spring clip and a rolling bearing 3100, the spring clip includes a first spring clip 1211 and a second spring clip 1212, the end of each first wire 1200 is connected to one first spring clip 1211, each conductive ring 2210 is also connected to one second spring clip 1212, the rolling bearing 3100 is located between the stationary end engagement mechanism 1000 and the movable end engagement mechanism 2000, the rolling bearing 3100 includes a moving ring 3110 and a stationary ring 3120 rotatably connected to the moving ring 3110, wherein the moving ring 3110 is fixed with a first sliding conductive member 3200 extending along the axial direction of the rolling bearing 3100 and inserted into the first spring clip 1211; a second sliding conductive member 3300 extending axially along the rolling bearing 3100 and inserted into the second spring catch 1212 is secured to the stationary ring 3120. With this arrangement, when the stationary end engagement mechanism 1000 and the movable end engagement mechanism 2000 are rotated, the movable ring 3110 and the stationary ring 3120 of the rolling bearing 3100 are also rotated in the same direction, that is, the sliding friction between the guide rod 1230 and the conductive ring 2210 in embodiment 1 is replaced by the rolling friction of the rolling bearing 3100, so that the wear is reduced.
In particular, the spring clip may be disposed in the hole, and the first sliding conductive member 3200 and the second sliding conductive member 3300 need to be disposed in the hole of the spring clip in the centering manner, so that the difficulty in installation is increased, the first sliding conductive member 3200 and the second sliding conductive member 3300 may be manufactured into a circular ring shape for easy installation to save installation time, or the spring clip 1210 may be manufactured into a circular ring shape, and after such arrangement, the first sliding conductive member 3200 and the second sliding conductive member 3300 may be quickly inserted into the spring clip no matter what angle the static end engagement mechanism 1000 and the moving end engagement mechanism are engaged. In addition, after the ring structure is adopted, it is necessary to limit the rotation of the first sliding conductive member 3200 and the second sliding conductive member 3300 relative to the spring clip 1210 around the central axis of the rolling bearing 3100 so as to reduce the abrasion between the first sliding conductive member 3200 and the second sliding conductive member 3300 and this can be achieved by controlling the clamping force of the spring clip on the first sliding conductive member 3200 and the second sliding conductive member 3300, of course, the greater the clamping force of the spring clip on the first sliding conductive member 3200 and the second sliding conductive member 3300, the greater the force is required to insert the first sliding conductive member 3200 and the second sliding conductive member 3300 into the spring clip, which may bring about the inconvenience of installation, so the present embodiment also provides a new embodiment in which friction strips extending along the axis of the rolling bearing 3100 are arranged on the contact surfaces of the first sliding conductive member 3200 and the second sliding conductive member 3300 and the spring clip 1210 so as to prevent the first sliding conductive member 3200 and the second sliding conductive member 3300 from rotating relative to the spring clip 1210.
