[0002] With the advancement of science and technology, more and more cabinets are used in data systems and information systems. These devices need to be equipped with a cooling liquid distribution unit (CDU) for heat dissipation. In order to ensure safe operation of the liquid-cooled CDU, a leakage monitoring system needs to be installed inside the equipment cabinet to prevent losses caused by leakage. In the prior art, a leakage monitoring sensor is set at the bottom of the cabinet, and an alarm is immediately sounded when a leakage occurs. However, when a leakage occurs, the corresponding reaction level should not be different depending on the amount of leakage, and the existing leakage detection device cannot make a distinction based on the amount of leakage. Taking the same reaction to different amounts of leakage will waste work efficiency. In addition, in the prior art, the leakage monitoring sensor is installed in the form of a strip on the bottom of the equipment, which is time-consuming and labor-intensive, and the connection with the controller is relatively complicated. Utility Model Content

[0003] The utility model aims to provide an improved liquid leakage detection structure, which aims to solve the technical problems that the liquid leakage detection device in the prior art cannot make a distinction according to the amount of leakage and is complicated to install.

[0006] Furthermore, it also includes four L-shaped connecting parts, the connecting parts are arranged on the lower side of the chassis, the weight sensing device or the supporting tripod is arranged at the bottom of the connecting parts, any one of the supporting tripods includes a screw rod and two nuts, the screw rod passes through the connecting part in the height direction, the two nuts are respectively arranged on the upper and lower sides of the connecting part and connected to the screw rod, and the lower end of the screw rod is provided with a support pad.

[0007] Furthermore, the liquid leakage detection device is a liquid leakage detection belt, and the liquid leakage detection belts are arranged parallel to each other.

[0008] Furthermore, the leakage detection devices are connected in series or in parallel.

[0009] Furthermore, the weight sensing device is a weighing sensor.

[0010] Furthermore, it also includes a display device, and the signal input end of the display device is signal-connected to the signal output end of the controller.

[0013] Working principle:

[0014] Various types of equipment are arranged on the upper and middle parts of an equipment cabinet, and a liquid-cooled CDU is arranged between these equipments. The liquid-cooled CDU is used to dissipate heat for these equipments. A chassis is arranged below these equipments, and a leakage detection belt is arranged on the upper side of the chassis. When the liquid-cooled CDU leaks, the coolant drips down onto the chassis and directly contacts the leakage detection belt, or contacts the leakage detection belt after diffusion. The leakage detection belt sends a signal to the controller after contacting the coolant. After receiving the signal, the controller can determine that a leakage has occurred. On this basis, this device adds a weighing sensor on the lower side of the chassis to sense the change in the weight of the chassis, that is, to collect data on the amount of leakage. When a leakage occurs, the weight on the chassis will gradually increase over time, and the weight information fed back by the weighing sensor to the controller will gradually increase. The weight information is monitored in the form of a change curve. When the weight of the leakage increases greatly in a short period of time, it means that the leakage is serious and needs to be maintained as soon as possible. When the weight of the leakage increases slowly over a period of time, it means that the leakage is not serious. The staff can prioritize the maintenance of other equipment according to the work arrangement, and then carry out this equipment cabinet.

[0015] Compared with the prior art, the utility model has the beneficial effects of assisting the staff to judge the leakage situation by detecting the change of the leakage weight, determining the order of maintenance work, and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The signal output end of the liquid leakage detection device 2 is connected to a controller (not shown in the figure) through a signal line. The structure also includes two weight sensing devices 3 and two supporting legs 5. The two weight sensing devices 3 and the two supporting legs 5 are arranged on the lower side of the chassis 1 along a rectangle.

The liquid leakage detection belt 2 can use the LK16-T2-2000HD oil detection sensor produced by Qingdao Jianyong Pneumatic and Hydraulic Co., Ltd., and the weight sensor 3 can use the column sensor produced by Changzhou Addis Weighing Equipment Co., Ltd.

[0033] The working process of this embodiment:

[0034] In case 1, the leakage detection belt 2 does not feedback leakage information, and the weight sensor 3 feedbacks that the weight has changed. It is determined that it is not a leakage accident, but a part may fall off;

[0035] In the second case, the leakage detection belt 2 feedbacks leakage information, and the weight sensor 3 feedbacks weight change. According to the preset threshold, if the weight change and weight increase are both less than the preset threshold, it can be determined that a small-scale leakage has occurred, and maintenance operations are performed according to normal maintenance standards, and other maintenance work can be handled with priority;

[0036] Case three, the leakage detection belt 2 feeds back leakage information, and the weight sensor 3 feeds back weight change, wherein, through the preset threshold, the comparison of weight change and weight increase are both greater than the preset threshold, it can be determined that a large-scale leakage has occurred and emergency maintenance is required, and the equipment cabinet is given priority maintenance.
