Description

Technical Field

[0001] The present application belongs to the field of sensor technology, and more specifically, relates to a water immersion sensor. Background Art

[0002] A water sensor is a sensor used to detect whether there is water leakage in the measured range. When the water sensor detects water around it, it will generate a corresponding signal to remind you to avoid various hazards and losses caused by water leakage. It is widely used in data centers, communication rooms, power stations, warehouses, archives and other places that require waterproofing. For example, a water sensor can monitor whether there is water leakage in places with water sources such as fire water pipes and domestic water pipes. Once a water leakage occurs, the water sensor will immediately issue an alarm to remind you to take timely measures to prevent the leakage accident from causing related losses and hazards. At the same time, the water sensor can also be linked with monitoring hosts and other equipment to achieve remote monitoring and automated management, and improve management efficiency and safety. In other words, the application of water sensors can effectively improve management efficiency, reduce unnecessary manpower consumption, improve safety and reliability, protect the safety of equipment and data, and reduce losses.

In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Please also read Figures 1 to 6 , the water immersion sensor provided in the embodiment of the present application is now described.

[0030] Please also read Figures 1 to 3The water immersion sensor includes: a sensor body 100, a probe 200 and a probe wire 300. The sensor body 100 includes a shell 10, a signal processing module 20 and a winding drum 30. The signal processing module 20 and the winding drum 30 are both arranged in the shell 10. The probe 200 is located outside the shell 10. One end of the probe wire 300 extends into the shell 10 and is electrically connected to the signal processing module 20. The other end of the probe wire 300 is electrically connected to the probe 200. The excess part of the probe wire 300 is wound on the winding drum 30.

[0031] The probe 200 is used to detect whether there is water in the measured range, and the probe line 300 is used to transmit the detection signal of the probe 200 to the signal processing module 20, and the signal processing module 20 is used to analyze and process the detection signal. For example, when the probe 200 contacts water, it can quickly change the resistance value or form a closed loop. The probe line 300 is used to transmit the change signal made by the probe 200 to the signal processing module 20. After the signal processing module 20 analyzes and processes the signal, it issues an alarm to remind the user to take timely measures.

[0032] The housing 10 is provided with a through hole 13, specifically, the through hole 13 is provided at the bottom of the housing 10, and the probe wire 300 is movably passed through the through hole 13. It can be understood that part of the probe wire 300 enters and exits the housing 10 through the through hole 13. The winding drum 30 is used to wind up the excess length of the probe wire 300. It can be understood that the excess part of the probe wire 300 is wound on the winding drum 30 and stored in the housing 10.

[0033] Compared with the prior art, the water immersion sensor provided by the present application has a probe 200 electrically connected to a signal processing module 20 through a probe line 300, so that the signal detected by the probe 200 is transmitted to the signal processing module 20 through the probe line 300. By arranging a winding drum 30 in the housing 10, the excess part of the probe line 300 is wound on the winding drum 30 and stored in the housing 10. This design has at least the following beneficial effects:

[0034] 1. It is beneficial to protect the probe wire 300 and ensure the accuracy of water immersion sensor detection: If the excess part of the probe wire 300 is exposed to the outside for a long time or placed randomly, it is easy to cause the probe wire 300 to wear and break, affecting the electrical performance and service life of the probe wire 300. At the same time, if the probe wire 300 is damaged, it may cause unstable or even interrupted signal transmission, affecting the accuracy of water immersion sensor detection. By winding the excess part of the probe wire 300 on the winding drum 30 and storing it in the housing 10, the excess part of the probe wire 300 is reasonably stored, which can effectively prevent the probe wire 300 from physical damage, chemical corrosion and being affected by environmental factors, and can ensure that the probe wire 300 is in good working condition, providing users with timely and accurate water leakage alarm information.

[0035] 2. It is conducive to extending the service life: By winding the excess part of the probe line 300 on the winding drum 30 and storing it in the housing 10, the probe line 300 is properly stored, which is conducive to reducing the risk of damage caused by human misoperation, such as excessive pulling, bending, etc. By winding the probe line 300 neatly on the cable drum, it is convenient to carry and deploy, and can prevent the cable from being damaged due to winding and knotting, thereby effectively extending the service life of the probe line 300.

[0036] 3. It is helpful to keep the usage scene neat and orderly: by winding the excess part of the probe line 300 on the winding reel 30 and storing it in the shell 10, the neatness of the on-site layout can be maintained, avoiding the safety hazards caused by the disorderly probe line 300, especially in data centers, computer rooms, warehouses and other environments that require long-term maintenance and management. Good wiring specifications help to quickly identify and locate the position of each sensor, which is convenient for daily inspections and emergency handling.

[0037] 4. It is helpful to improve work efficiency: when the water immersion sensor needs to be redeployed or moved, the probe line 300 wound on the winding reel 30 can be quickly unwound and the length adjusted, and the probe 200 can be correctly placed in the corresponding position, which is helpful to save time and improve work efficiency.

[0038] 5. Wide range of applications: By winding the probe wire 300 on the winding reel 30, the length of the probe wire 300 extending outside the shell 10 can be adjusted. In this way, the user can adjust the length of the probe wire 300 extending outside the shell 10 according to the usage scenario and needs.
