[0025] Reference Figures 1 to 5 According to the first-stage pipe joint assembly for the energy storage station cooling system of a preferred embodiment of the present application, which will be described in detail below, the first-stage pipe joint assembly for the energy storage station cooling system comprises a first joint piece 10, a pair of second joint pieces 20 and a plurality of connecting units 30, wherein the first joint piece 10 has a first channel 101 passing through both ends inside, for the flow of fluid in the pipe. Each of the second joint pieces 20 has a second channel 201 passing through both ends inside, and the two ends of the first joint piece 10 are respectively detachably connected to one of the second joint pieces 20, so that the first channel 101 and the second channel 201 are in communication.

[0026] It should be noted that the end of each of the second joint pieces 20 away from the first joint piece 10 is used to communicate the pipe, so that the fluid flowing in the pipe can gradually flow from one of the second channels 201 through the first channel 101, and can then flow out from another of the second channels 201.

[0027] Moreover, each of the second joint members 20 is configured to form at least one clamping groove 1001 in cooperation with the first joint member 10 when the second joint member 20 is connected to the first joint member 10. Each of the connection units 30 is connected to one of the clamping grooves 1001 in a radial direction of the second joint member 20, and each of the connection units 30 is configured to abut against an inner wall of the clamping groove 1001 in an axial direction of the second joint member 20.

[0028] As understood by those skilled in the art, when the second joint member 20 is connected to the first joint member 10 to form the clamping groove 1001, the connection unit 30 connected to the clamping groove 1001 simultaneously abuts against the inner wall of the clamping groove 1001 formed by the first joint member 10 and the second joint member 20, so that the first joint member 10 and the second joint member 20 are difficult to be separated in the same axial direction. When the connection unit 30 is moved in the radial direction of the second joint member 20 to be separated from the clamping groove 1001, the first joint member 10 and the second joint member 20 can be separated in the same axial direction due to the absence of the abutment of the connection unit 30.

[0029] In this way, the first joint member 10 and the second joint member 20 can be kept in a fixed connection position by the connection unit 30, and when the first joint member 10 or the second joint member 20 needs to be replaced, the connection unit 30 can be separated from the clamping groove 1001 to release the fixed connection position of the first joint member 10 and the second joint member 20, so that the first joint member 10 and the second joint member 20 can be separated from each other to replace the new first joint member 10 or the new second joint member 20.

[0032] Preferably, the first joint member 10 is arranged to extend radially outwardly in one piece to form a guide portion 12 at the predetermined position connected with the second joint member 20, the guide portion 12 is arranged behind the extension portion 11 in the direction of insertion, and the guide portion 12 has an arc-shaped guide surface with the convexity of the arc in the same direction as the extension direction of the extension portion 11.
