DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Embodiment one

[0026] Please refer to the drawings Figures 1-4 A water cooling pipe connecting valve convenient to replace for a power distribution cabinet, comprising:

[0027] Connecting pipe 1, connecting flange 2 and pipe clamp 3, the connecting pipe 1 is provided with a valve 4 matched with it, the connecting flange 2 is fixedly connected to the connecting pipe 1 and the cooling pipe 5 respectively, the pipe clamp 3 is movably connected with the connecting flange 2, the water leakage alarm assembly 6 comprises an outer pipe 60, an annular sealing disc 61 and a humidity sensor 62, the outer pipe 60 is movably connected to the cooling pipe 5, the humidity sensor 62 is movably connected to the curved side wall of the outer pipe 60, and the annular sealing disc 61 is located between the connecting flange 2 and the valve 4, and is slidably connected with the connecting pipe 1 and screwedly connected with the outer pipe 60.

[0028] The connecting pipe 1 and the cooling pipe 5 are directly disassembled and replaced by using the flange 2 and the pipe clamp 3, and the method is simple and efficient, and basically no auxiliary tool is needed, and the practicability is stronger for the limited space in the power distribution cabinet.

[0029] At the same time, the initial stage of the water leakage of the water cooling system is difficult to be detected, so the water leakage alarm component 6 is arranged, a relatively closed small space is formed at the connecting flange 2 where the water leakage is most likely to occur through the outer pipe 60 and the annular sealing disc 61, and the humidity of the space is detected through the arranged humidity sensor 62. In the normal use process, if water seeps at the connecting flange 2, the humidity of the closed space will change after the water seepage evaporates. If the humidity in the closed space exceeds the standard and the humidity continuously rises, it means that water leakage occurs. The staff can monitor the water leakage in time and maintain or replace the connecting pipe 1 to avoid more serious losses caused by continuous water leakage.

[0030] Specifically, the pipe clamp 3 includes two groups of semi-annular clamp bodies 30 and a group of locking components 31. One end of each group of the semi-annular clamp bodies 30 is hingedly connected to each other. The locking component 31 includes two groups of U-shaped clamping blocks 310, a connecting rod 311, a screw rod 312, and a locking cap 313. Each group of the U-shaped clamping blocks 310 is fixedly connected to the convex side wall of the non-contact end of each group of the semi-annular clamp bodies 30. The connecting rod 311 penetrates through the screw rod 312 and is slidably connected to the screw rod 312. The two ends of the connecting rod 311 are fixedly connected to the inner wall of the gap of each U-shaped clamping block 310. The locking cap 313 is threadedly connected to the end of the screw rod 312 away from the connecting rod 311.

[0031] The position of the connecting flange 2 on the connecting pipe 1 and the cooling pipe 5 is limited by the cooperation of the two groups of semi-annular clamp bodies 30. When disassembling, the two groups of semi-annular clamp bodies 30 can be tightened and loosened by the threaded connection of the locking cap 313 and the screw rod 312. In the loosened state, the screw rod 312 and the locking cap 313 can be rotated to the side away from the U-shaped clamping block 310 through the sliding connection of the screw rod 312 and the connecting rod 311, so as to avoid interfering with the opening of the two groups of semi-annular clamp bodies 30.

[0032] Specifically, the diameter of the locking cap 313 is greater than the height of the gap of the U-shaped clamping block 310, and anti-skid lines 3130 are engraved on the curved side wall of the locking cap 313. The setting that the diameter of the locking cap 313 is greater than the height of the gap of the U-shaped clamping block 310 ensures that the locking cap 313 does not pass through the gap of the U-shaped clamping block 310 when the position of the two groups of semi-annular clamp bodies 30 is locked by the screw rod 312 and the locking cap 313, thereby preventing the semi-annular clamp bodies 30 from being unable to be positionally locked. The anti-skid lines 3130 on the locking cap 313 are arranged to make the tightening and loosening of the locking cap 313 easier.

[0033] Specifically, the concave surface of the semi-annular hoop body 30 is provided with a clamping groove 301, and the clamping groove 301 is provided with a rubber ring matched therewith; considering that the object to be fixed by the pipe hoop 3 is a water pipe, in order to avoid the situation of water leakage, the rubber ring is used to complete the sealing of the pipe hoop 3, and it is worth noting that the rubber ring here can not only adopt the traditional separated water sealing ring, but also can adopt the direct filling of the glue filling material in the clamping groove 301 to complete the sealing, the former has strong replaceability, and the latter simplifies the steps in the replacement, and each has advantages and disadvantages.

[0034] Embodiment two

[0035] Please refer to the accompanying drawings Figure 5

[0036] Specifically, the connecting flange 2 comprises an inner flange 20 and an outer flange 21, the inner flange 20 is provided with an annular groove 200 on the plane side wall, the outer flange 21 is provided with an annular protrusion 210 matched with the annular groove 200 on the plane side wall, and the outer flange 21 is provided with an annular outer wall 211 integrally formed on the curved outer side wall.

[0037] Specifically, the annular groove 200 and the annular outer wall 211 are respectively provided with a rubber waterproof ring 22 matched therewith;

[0038] Considering that there are many electronic components in the power distribution cabinet, once water leakage occurs, the consequences are serious, in order to further strengthen the waterproof, the connecting flange 2 adopts the mode of matched use of the inner flange 20 and the outer flange 21, because the annular groove 200 and the annular protrusion 210 and the annular outer wall 211 are arranged, the inner flange 20 and the outer flange 21 after embedding are divided into multiple layers of concave-convex structures, and different diameter rubber waterproof rings 22 are arranged between the multiple layers, so that better waterproof effect is achieved.

[0039] Embodiment three

[0040] Please refer to the accompanying drawings Figure 6

[0041] Specifically, the connecting pipe 1 is provided with an extension pipe 10, the extension pipe 10 is a metal corrugated pipe, and the two ends of the extension pipe 10 are provided with connecting flanges 2 fixedly connected therewith;

[0042] Considering that in actual application, the length of the connecting pipe 1 may not match the interface position of the cooling pipe 5, for example, in the replacement of new and old power distribution cabinets, the length of the connecting valve suitable for the new power distribution cabinet is not customized in time, or the electronic components in the power distribution cabinet are repaired, resulting in misalignment of the cooling pipe 5, therefore, the extension pipe 10 suitable for the above-mentioned situation is additionally provided, when the newly customized accessories are not available, the length and position are corrected by using the characteristics of the corrugated pipe material of the extension pipe 10.

[0043] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
