[0067] A detailed description of specific embodiments of the application is described below with reference to the accompanying drawings.

[0068] As shown in Figure 1 and Figure 2 The present embodiment provides a cable core cooling system 100, which includes a liquid collecting assembly 10, a cooling pipeline 20, a liquid inlet valve set 30, a water vapor containing member 40, a liquid return valve set 50, a liquid level detecting member 60, and a control assembly 70.

[0069] The liquid collecting assembly 10 is configured to store cooling liquid, which can be a cooling medium such as cooling water, and the liquid collecting assembly 10 can be a water tank or the like. The cooling pipeline 20 is configured to accommodate a cable core, which can be a cable core of a cross-linked cable or the like. The cable core is arranged in the cooling pipeline 20 and can be moved in the cooling pipeline 20 by a traction device (not shown in the figure). One end of the liquid inlet valve set 30 is connected to the liquid collecting assembly 10, and the other end of the liquid inlet valve set 30 is connected to a liquid inlet end 21 of the cooling pipeline 20. The liquid inlet valve set 30 is configured to deliver the cooling liquid in the liquid collecting assembly 10 into the cooling pipeline 20. When the cooling liquid flows through the cooling pipeline 20, the cooling liquid can exchange heat with the cable core, thereby cooling the cable core by taking away the heat of the cable core through the cooling liquid.

[0070] Along the extension direction of the cooling pipe 20, the cooling pipe 20 has an inlet end 21 and an outlet end 22 arranged opposite to each other. A water vapor containment device 40 is connected to the outlet end 22 of the cooling pipe 20. The water vapor containment device 40 can be a water vapor tank, etc., which can temporarily store the coolant flowing out from the outlet end 22 of the cooling pipe 20. One end of the return valve assembly 50 is connected to the water vapor containment device 40, and the other end of the return valve assembly 50 is connected to the liquid collection assembly 10. A liquid level detection device 60 is configured to detect the liquid level height within the water vapor containment device 40. The liquid level detection device 60 is a device capable of detecting liquid level height, such as a magnetic level gauge, and is located within the water vapor containment device 40. A control assembly 70 is signal-connected to the liquid level detection device 60 and the return valve assembly 50. Based on the liquid level height detected by the liquid level detection device 60 within the water vapor containment device 40, the control assembly 70 is configured to adjust the opening degree of the return valve assembly 50.

[0071] Thus, the cable core cooling system 100 of this application, by providing a water vapor containment device 40 at the outlet end 22 of the cooling pipe 20, can store the coolant flowing out of the cooling pipe 20, and the liquid level in the water vapor containment device 40 is detected by the liquid level detection device 60, so that the control component 70 can dynamically adjust the opening of the return valve assembly 50 according to the current liquid level in the water vapor containment device 40, thereby ensuring that the liquid level in the water vapor containment device 40 is within a suitable range, so as to maintain the water vapor balance of the cable core cooling system 100 and ensure the cooling effect of the cable core.

[0072] Please combine Figure 3 and Figure 4 And see Figure 1 In one embodiment, the liquid inlet valve assembly 30 includes a first liquid inlet module 31 and a second liquid inlet module 32. One end of the first liquid inlet module 31 is connected to the liquid collection assembly 10, one end of the second liquid inlet module 32 is connected to the end of the first liquid inlet module 31 away from the liquid collection assembly 10, and the other end of the second liquid inlet module 32 is connected to the liquid inlet end 21 of the cooling pipe 20. After flowing out of the liquid collection assembly 10, the coolant passes through the first liquid inlet module 31 and the second liquid inlet module 32 in sequence and then enters the cooling pipe 20 from the liquid inlet end 21.

[0073] The inlet valve assembly 30 also includes a first pressure detection element 33 and a second pressure detection element 34. Both the first pressure detection element 33 and the second pressure detection element 34 are digital display pressure gauges or other detection devices that can read the detected pressure values ​​in real time. The first pressure detection element 33 is located on the pipeline between the first inlet module 31 and the second inlet module 32 to detect the pressure of the pipeline where the coolant enters the second inlet module 32.

[0074] The second pressure detection element 34 is installed on the pipeline between the second liquid inlet module 32 and the cooling pipeline 20 to detect the pressure of the coolant pipeline after leaving the second liquid inlet module 32.

[0075] Thus, by comparing the difference of the pressures detected by the first pressure detecting member 33 and the second pressure detecting member 34, the working states of the first liquid inlet module 31 and the second liquid inlet module 32 can be adjusted to ensure that the pressure fluctuation in the cooling pipeline 20 is not too large, and the cooling effect of the cable core is guaranteed.

[0076] Please combine Figure 3 and Figure 4 , and refer to Figure 1 In an embodiment, the first liquid inlet module 31 can pressurize the cooling liquid to 8-10 kg and then deliver it into the cooling pipeline 20. The first liquid inlet module 31 includes a first on-off valve 311, a pumping member 312, and a second on-off valve 313 connected in sequence. The first on-off valve 311 is connected to the liquid collecting assembly 10 away from the pumping member 312. The second on-off valve 313 is connected to the second liquid inlet module 32 away from the pumping member 312.

[0077] The first on-off valve 311 is a ball valve for realizing the on-off of the pipeline between the pumping member 312 and the liquid collecting assembly 10. The second on-off valve 313 is a ball valve for realizing the on-off of the pipeline between the pumping member 312 and the second liquid inlet module 32.

[0078] It can be understood that in other embodiments, the first on-off valve 311 and the second on-off valve 313 can also be other valve members having the function of opening or closing the pipeline.

[0079] The pumping member 312 is a centrifugal pump that can pump out the cooling liquid stored in the liquid collecting assembly 10. The pumping member 312 can provide power for the flow of the cooling liquid to ensure that the cooling liquid can circulate in the cable cooling system 100, realizing the recycling of the cooling liquid. It is worth noting that a condensing device or other device that can cool the cooling liquid can be arranged in the liquid collecting assembly 10 to facilitate the recycling of the cooling liquid.

[0080] In particular, the pumping member 312 is started and stopped in a variable frequency control manner to avoid tripping or burning of electrical elements when the pumping member 312 is started, and to eliminate the water hammer effect of the pumping member 312 during starting and stopping.

[0081] In this embodiment, the first liquid inlet module 31 further includes a first filter 314 and a first check valve 315.

[0082] The first filter 314 is located between the first on-off valve 311 and the pumping member 312, and the first filter 314 is connected to the first on-off valve 311 and the pumping member 312. The first filter 314 is a Y-type filter or the like, which can filter the cooling liquid entering the pumping member 312 to avoid damage to the pumping member 312 caused by impurities in the cooling liquid.

[0083] The first check valve 315 is located between the second switch valve 313 and the pumping member 312, and the first check valve 315 communicates the second switch valve 313 and the pumping member 312 to avoid the backflow of the cooling liquid into the pumping member 312.

[0084] In particular, the first filtering member 314 and the pumping member 312 are connected through a flexible joint 316 to achieve the flexible connection of the pipeline between the first filtering member 314 and the pumping member 312, and the flexible joint 316 is made of rubber or the like. The first check valve 315 and the pumping member 312 are connected through a flexible joint 316 to achieve the flexible connection of the pipeline between the first check valve 315 and the pumping member 312, and the flexible joint 316 is made of rubber or the like.

[0085] In the embodiment, the first liquid inlet module 31 further comprises a third pressure detection member 317. The third pressure detection member 317 is arranged between the pumping member 312 and the first check valve 315, and the third pressure detection member 317 is a pressure gauge to detect the pressure of the pipeline where the cooling liquid flows out of the pumping member 312.

[0086] In the embodiment, in one embodiment, the number of the first liquid inlet modules 31 is at least two, and the at least two first liquid inlet modules 31 are arranged in parallel between the liquid collecting assembly 10 and the second liquid inlet module 32, and any one of the at least two first liquid inlet modules 31 communicates with the liquid collecting assembly 10 and the second liquid inlet module 32.

[0087] In this way, the first liquid inlet module 31 is provided in multiple, which not only enables other first liquid inlet modules 31 to be used to ensure the normal operation of the cable cooling system 100 when one first liquid inlet module 31 is damaged, but also enables at least two first liquid inlet modules 31 to be opened simultaneously to achieve the effect of quickly supplementing the cooling liquid when the supply of the cooling liquid in the cooling pipeline 20 is insufficient.

[0088] Please refer to Figure 3 and Figure 4 , and refer to Figure 1 , in one embodiment, the second liquid inlet module 32 comprises a filtering module 321 and a switch module 322. One end of the filtering module 321 communicates with the first liquid inlet module 31, and the filtering module 321 is configured to filter the cooling liquid. One end of the switch module 322 communicates with the filtering module 321 away from the end of the first liquid inlet module 31, and the other end of the switch module 322 communicates with the liquid inlet end 21 of the cooling pipeline 20.

[0089] The filtering module 321 comprises a second filtering member 3211 and a second check valve 3212 which are communicated in sequence. The end of the second filtering member 3211 away from the second check valve 3212 communicates with the second switch valve 313, and the end of the second check valve 3212 away from the second filtering member 3211 communicates with the switch module 322.

[0090] The second filter 3211 is a Y-type filter or the like, which is used to filter the coolant delivered from the pumping member 312. The second check valve 3212 is used to prevent the coolant from flowing back into the second filter 3211.

[0091] In particular, the number of the filter modules 321 is set to be at least two, and the at least two filter modules 321 are arranged in parallel between the first liquid inlet module 31 and the switching module 322. Each of the at least two filter modules 321 is connected to the second switching valve 313 and the switching module 322. In this way, the arrangement of the at least two filter modules 321 not only enables other filter modules 321 to be turned on to filter the coolant when the currently working filter module 321 fails, but also enables the at least two filter modules 321 to be turned on simultaneously to filter the coolant with large flow when the coolant supply in the coolant pipeline 20 is insufficient and multiple first liquid inlet modules 31 are opened.

[0092] In the present embodiment, the switching module 322 includes two first stop valves 3221.

The third switching valve 3222 is arranged between one first stop valve 3221 and the filter module 321, and is connected to the first stop valve 3221 and the filter module 321. The third switching valve 3222 is a pneumatic ball valve, and can automatically open or close the pipeline where the third switching valve 3222 is arranged.

[0098] Please refer to Figure 6 , and refer to Figure 1 , in an embodiment, the cable cooling system 100 further comprises a drainage valve group 80, which is used to drain the cooling liquid in the pipeline into the liquid collecting assembly 10 after the cable cooling system 100 is stopped.
