[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In the description of the present utility model, "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] In industrial production, equipment usually generates a lot of heat. If the heat is not dissipated in time, it will cause the equipment to overheat and affect the stable operation of the equipment. For example, in a semiconductor processing plant, the power modules of equipment such as plasma, lasers, ion accelerators and robots used to produce semiconductors need to be water-cooled. Specifically, a cooling pipeline will be set in the power module. The cooling pipeline has an inlet end and a return end. The inlet end is connected to the external inlet pipe through a joint unit, and the return end is connected to the external return pipe through a joint unit. The cooling water in the inlet pipe enters the cooling pipeline to cool the power module, and then flows back to the return pipe.

[0041] These devices are of high value. If a leak occurs and is not handled in time, it is easy to cause huge property losses. In the related art, a water receiving tray is set under the joint unit, and the water receiving tray is provided with a leak detector such as a leak detection belt. When a leak occurs in the joint unit, the cooling water drips into the water receiving tray, and the leak detector senses it and sounds an alarm. However, when the water pressure is too high, the cooling water may spray and fail to drip into the water receiving tray, which may cause the leak detector to fail to detect the leak in time. In addition, the cooling water is easy to spray into the power module and damage the power module, which has poor safety.

[0042] Therefore, the utility model provides a water leakage detection and protection device, which can effectively solve the above problems.

[0043] Reference below Figures 1 to 6 A water leakage detection and protection device according to an embodiment of the utility model is described.

The cooling water in the water inlet pipe 900 enters the cooling pipeline through one of the connecting pipes 100 to cool the power module 800. After working, the cooling water flows back to the return pipe 901 from the other connecting pipe 100.

[0050] According to the water leakage detection and protection device of the embodiment of the utility model, since the two first joint units 200 are both accommodated in the first water receiving box 300, even if there is a jet leakage at the first joint unit 200, due to the blocking effect of the first water receiving box 300, it will not be sprayed onto the power module 800 and damage the power module 800, but will be sprayed onto the inner wall of the first water receiving box 300 and flow to the bottom end of the first water receiving box 300, so that it will be detected in time by the first water leakage detector 400, and the staff can close the pipeline in time to avoid causing significant property losses.

[0053] For example, the two second joint units 500 are respectively connected to the ends of the two connecting pipes 100 away from the first joint unit 200. The second joint unit 500 can be various types of joints, which will not be described in detail here. The second joint unit 500 can be welded, threaded, or clamped with the connecting pipe 100, and the water inlet pipe 900 and the water return pipe 901 can be provided with a connector 902. The second joint unit 500 can be welded, threaded, or clamped with the connector 902 on the water inlet pipe 900 and the water return pipe 901. The second water receiving box 600 can be square, and a second accommodating cavity is formed in the second water receiving box 600. The second water receiving box 600 can be provided with second clearance holes on opposite sides. The connector 902 and the connecting pipe 100 are inserted in the corresponding second clearance holes, and the second joint unit 500 is accommodated in the second accommodating cavity of the second water receiving box 600. The second water receiving box 600 is provided, and even if the second joint unit 500 leaks and a spraying phenomenon occurs, the spraying phenomenon can only be applied to the inner wall of the second water receiving box 600, and will not be applied to the outer side of the second water receiving box 600. The second water leakage detector 700 is provided at the bottom of the second water receiving box 600. When the second joint unit 500 leaks, the cooling water will flow to the second water leakage detector 700, and the second water leakage detector 700 can sense and send out an alarm, thereby reminding the staff to take timely measures.

[0054] In the present embodiment, since the two second joint units 500 are both accommodated in the second water receiving box 600, even if water jet leakage occurs at the second joint unit 500, due to the blocking effect of the second water receiving box 600, the water will not be sprayed to the outside, but will be sprayed to the inner wall of the second water receiving box 600 and flow to the bottom end of the second water receiving box 600, thereby being detected in time by the second water leakage detector 700, and the staff can close the pipeline in time to avoid causing major property losses.

[0055] It should be noted that two second water receiving boxes 600 may be provided, and the two second joint units 500 are respectively accommodated in the two second water receiving boxes 600. In this case, two second water leakage detectors 700 may be provided and located at the bottom ends of the second water receiving boxes 600. In addition, only one second water receiving box 600 may be provided, and two second joint units 500 are simultaneously accommodated in one second water receiving box 600. In this case, one second water leakage detector 700 may be provided.

The two water flow sensors 501 are used to respectively detect the flow of water entering one of the connecting pipes 100 from the water inlet pipe 900, and the flow of water entering the return pipe 901 from the other connecting pipe 100. If there is no water leakage, the difference in the flow detected by the two water flow sensors 501 will be very small. If there is a water leakage, the difference in the flow detected by the two water flow sensors 501 will be large. Therefore, the staff can quickly determine whether there is a water leakage based on the difference in the flow detected by the two water flow sensors 501, which is more convenient to use.

[0057] It should be noted that the installation directions of the two water flow sensors 501 need to be set according to the flow direction of water in the corresponding second joint unit 500. The water flow sensor 501 is a common sensor capable of detecting water flow, and its structure and working principle are not described in detail here.

For example, the water leakage detection and protection device may also include a controller, the water flow sensor 501 and the automatic valve 502 are both connected to the controller, and the flow signal detected by the water flow sensor 501 is sent to the controller. When the controller receives that the difference in flow rates detected by the two water flow sensors 501 is greater than a preset value, the controller controls the automatic valve 502 to close the corresponding second joint unit 500, thereby preventing continued water leakage and causing significant property losses. Compared with manually closing valves, the degree of automation is higher, the use is more convenient, and the processing is faster, which can reduce property losses.
