Since the fluid passages in the mating socket 7 and the mating plug 6 are closed when they are separated, the cooling liquid in the liquid inlet pipe 4 and the liquid outlet pipe 5 cannot flow out, and the safety of the shooting site is ensured.
[0047] In some embodiments, the mating plug 6 and one end of the mating socket 7 are provided with the same mating portion 60, and the other end of the mating plug 6 and the mating socket 7 are provided with the plug portion 61 and the socket portion 70, respectively. The mating plug 6 is inserted into the socket portion 70 through the plug portion 61 to mate with the mating socket 7. The fluid passage in the mating plug 6 penetrates through the mating portion 60 and the plug portion 61, and the fluid passage in the mating socket 7 penetrates through the mating portion 60 and the socket portion 70. It can be understood that the socket portion 70 can be provided with a mating port 71 along the axial direction thereof, and the plug portion 61 can be a column structure extending along the axial direction of the mating plug 6. The plug portion 61 is inserted into the mating port 71 to achieve the mating of the two, and the mating port 71 is connected to the fluid passage to achieve the connection of the fluid passages of the mating plug 6 and the mating socket 7.
[0048] In some embodiments, one end of the mating plug 6 and the mating socket 7 is provided with the same mating portion 60. Taking the first liquid inlet pipe section 40 and the second liquid inlet pipe section 41 as an example, the mating plug 6 can be installed on the inlet end or the outlet end of the first liquid inlet pipe section 40 through the mating portion 60, or the mating socket 7 can be installed on the inlet end or the outlet end of the first liquid inlet pipe section 40 through the mating portion 60, which can simplify the assembly process and is suitable for quick mating installation.
[0049] In some embodiments, the mating portion 60 can be a column structure extending along the axial direction of the mating plug 6 and the mating socket 7. The mating portion 60 of the mating plug 6 and the mating portion 60 of the mating socket 7 are consistent in shape and size, so that the mating plug 6 or the mating socket 7 can be inserted into different pipe sections through the mating portion 60. The mating portion 60 and the plug portion 61 in the mating plug 6 can be coaxially arranged, and the mating portion 60 and the socket portion 70 in the mating socket 7 can be coaxially arranged.
[0050] In some embodiments, the fluid passage of the mating plug 6 is further provided with a first valve that can be opened and closed, and the fluid passage of the mating socket 7 is further provided with a second valve that can be opened and closed. The first valve and the second valve are configured to open when the mating plug 6 mates with the mating socket 7 to make the fluid passages of the mating plug 6 and the mating socket 7 conductive, and to close when the mating plug 6 and the mating socket 7 are separated to make the fluid passages of the mating plug 6 and the mating socket 7 closed, so that the cooling liquid cannot leak out.
[0051] In some embodiments, the first valve and the second valve can be electrically controlled valves. For example, a laser emitter can be arranged on the outer wall of the plug portion 61, and a laser receiver can be arranged on the inner wall of the mating surface 71 of the socket portion 70. When the plug portion 61 is properly mated with the socket portion 70, the laser receiver can receive the laser emitted by the laser emitter, and the laser receiver can send a control signal to open the first valve and the second valve. When the plug portion 61 is separated from the socket portion 70, the laser receiver cannot receive the laser emitted by the laser emitter, and the laser receiver can send a control signal to close the first valve and the second valve.
[0052] In some embodiments, the first valve and the second valve can also be mechanically controlled valves. Specifically, the plug 6 can further include a first elastic member and a first needle. The first valve can be rotatably arranged in the fluid channel of the plug 6. One end of the first elastic member can be connected to the inner wall of the fluid channel of the plug 6, and the other end of the first elastic member can be connected to the first valve. One end of the first needle can be fixed in the fluid channel of the plug 6 and located outside the first valve, and the other end of the first needle can extend out of the fluid channel of the plug 6. In the state that the plug 6 is separated from the socket 7, the first valve covers the cross section of the fluid channel of the plug 6, and the first valve abuts against the inner wall of the fluid channel, so that the fluid channel in the plug 6 is closed.
[0053] The socket 7 can further include a second elastic member and a second needle. The second valve can be rotatably arranged in the fluid channel of the socket 7. One end of the second elastic member can be connected to the inner wall of the fluid channel of the socket 7, and the other end of the second elastic member can be connected to the second valve. One end of the second needle can be fixed in the fluid channel of the socket 7 and located outside the second valve, and the other end of the second needle can extend out of the fluid channel of the socket 7. In the state that the plug 6 is separated from the socket 7, the second valve covers the cross section of the fluid channel of the socket 7, and the second valve abuts against the inner wall of the fluid channel, so that the fluid channel in the socket 7 is closed.
[0054] When the plug 6 is mated with the socket 7, the first needle and the second needle push the second valve and the first valve, respectively, so that the second valve and the first valve rotate inward, thereby making the fluid channels in the plug 6 and the socket 7 conductive. When the plug 6 is separated from the socket 7, the first needle and the second needle are separated from the second valve and the first valve, respectively, and the first elastic member and the second elastic member restore the first valve and the second valve, respectively, so that the fluid channels in the plug 6 and the socket 7 are closed.
[0055] In some embodiments, the external liquid cooling system further comprises a docking water nozzle 9. The docking water nozzle 9 has a first connecting part 90 and a second connecting part 91 at two ends respectively, the first connecting part 90 can be connected with the outlet end of the first liquid inlet pipe section 40, the inlet end of the second liquid inlet pipe section 41, the outlet end of the first liquid outlet pipe section 50 and the inlet end of the second liquid outlet pipe section 51, and the second connecting part 91 can be connected with the docking part 60.

The first connecting part 90 is provided with a first through hole 93 along its axis direction, and the second connecting part 91 is provided with a second through hole 94 along its axis direction, the first through hole 93 and the second through hole 94 are connected in communication to form a channel for the flow of cooling liquid.

Specifically, when the first connecting part 90 is inserted into the outlet end of the first liquid inlet pipe section 40, the inlet end of the second liquid inlet pipe section 41, the outlet end of the first liquid outlet pipe section 50, and the inlet end of the second liquid outlet pipe section 51, the first sealing ring tightly abuts against the inner wall of the outlet end of the first liquid inlet pipe section 40, the inlet end of the second liquid inlet pipe section 41, the outlet end of the first liquid outlet pipe section 50, and the inlet end of the second liquid outlet pipe section 51, thereby achieving a sealing effect and preventing the cooling liquid from leaking.
