Abstract
Description
Technical Field
[0001] This application relates to the technical field of water immersion detection, and in particular, to a photoelectric water immersion sensor and a water immersion monitoring system. Background Art
[0002] A water immersion sensor is a sensor that detects whether water leakage occurs in the measured range. Once water leakage occurs, an alarm is immediately issued to prevent relevant losses and hazards caused by water leakage accidents. Water immersion sensors are widely used in all waterproof places such as data centers, communication machine rooms, power stations, warehouses, and archives.

Normally, the two-pole probes are insulated by air; in the water immersion state, the probes are conducted, and the sensor outputs a dry contact signal.

[0030] A water immersion sensor is a sensor that detects whether water leakage occurs in the measured range. Once water leakage occurs, an alarm is immediately issued to prevent relevant losses and hazards caused by water leakage accidents. Water immersion sensors are widely used in all waterproof places such as data centers, communication machine rooms, power stations, warehouses, and archives.
[0031] In the related art, most water immersion sensors are contact water immersion sensors, which use the principle of liquid conductivity for detection. Normally, the two-pole probes are insulated by air; in the water immersion state, the probes are conducted, and the sensor outputs a dry contact signal.
[0032] However, the detection accuracy of this kind of contact water immersion sensor is relatively low.
[0033] In order to solve the above problems, the embodiments of this application provide a photoelectric water immersion sensor. The following will detail the solutions provided by the embodiments of this application in conjunction with the accompanying drawings of the specification.
[0034] Figure 1 is the overall structural schematic diagram of the photoelectric water immersion sensor provided by an embodiment of this application;
[0035] Figure 2 is Figure 1 Internal schematic diagram of the photoelectric water immersion sensor in
[0036] In the first aspect, referring to Figure 1 and Figure 2 shown, an embodiment of the present application provides a photoelectric water immersion sensor, including a housing 100, a control board 200, a signal transmitting part 300, a signal receiving part 400, a photoelectric signal barrier 500, and an end housing 600. Among them, the control board 200 is disposed in the housing 100, and the control board 200 is connected to a single-chip microcomputer or a PLC controller through a wire, which is the prior art and will not be elaborated here.
[0037] The signal transmitting part 300 is disposed in the housing 100 and is electrically connected to the control board 200; the signal receiving part 400 is disposed in the housing 100 and is electrically connected to the control board 200; the photoelectric signal barrier 500 is disposed between the signal transmitting part 300 and the signal receiving part 400 for blocking the photoelectric signal emitted by the signal transmitting part 300 to prevent the photoelectric signal from directly reaching the signal receiving part 400 from the signal transmitting part 300. The end housing 600 is disposed at the end of the housing 100, and the end housing 600 selectively reflects the photoelectric signal emitted by the signal transmitting part 300 to the signal receiving part 400, thereby determining whether a water leakage problem occurs in the measured range.
[0038] Specifically, when there is no water leakage problem, most of the photoelectric signals emitted by the signal transmitting part 300 can be irradiated on the signal receiving part 400 after being reflected by the end cover. At this time, the signal receiving part 400 will generate a relatively large voltage value. When a water leakage problem occurs, after the end housing 600 comes into contact with water, most of the photoelectric signals emitted by the signal transmitting part 300 are refracted out from the inside of the end housing 600, and most of the photoelectric signals cannot reach the signal receiving part 400, and the voltage value corresponding to the signal receiving part 400 decreases. By detecting the voltage change value at the signal receiving part, it can be determined whether a water leakage problem occurs in the corresponding detection area. Exemplarily, the photoelectric signal emitted by the signal transmitting part 300 is infrared light with a wavelength of 940 nm.
[0039] Compared with the contact type water immersion sensor in the prior art, this photoelectric water immersion sensor does not rely on the conductivity of the liquid to judge the water leakage problem, thereby providing higher detection accuracy and faster response time.
[0040] Continue to refer to Figure 2As shown, exemplary, the protruding size of the optoelectronic signal barrier 500 is greater than or equal to the protruding sizes of the signal transmitting part 300 and the signal receiving part, separating the signal transmitting part 300 and the signal receiving part 400, so that the optoelectronic signal emitted by the signal transmitting part 300 cannot directly reach the signal receiving part 400, thereby making the difference in the number of optoelectronic signals received by the signal receiving part 400 with and without water relatively large, generating a relatively large voltage difference.
[0041] In addition, exemplary, the material of the end shell 600 is configured to be able to transmit optical signals, and its refractive index is equal to that of the air.
[0042] Figure 3 is Figure 1 the installation schematic diagram of the optoelectronic water immersion sensor in
[0043] Referring to Figure 3 As shown, the optoelectronic water immersion sensor further includes a mounting bracket 700. The mounting bracket 700 is in a right-angled shape. One end of the mounting bracket 700 is fixedly connected to the housing 100, thus facilitating the fixation of the housing 100. In addition, in other examples, an alarm light is provided on the control board 200. When it is detected that there is a water leakage problem, the alarm light flashes to give an alarm. The optoelectronic water immersion sensor is corrosion-proof as a whole and can be used in various harsh environments, being fully sealed and corrosion-resistant.
[0044] In a second aspect, the embodiments of the present application further provide a water immersion monitoring system, including the optoelectronic water immersion sensor in any one of the above technical solutions, and thus having all the beneficial effects of the optoelectronic water immersion sensor in any one of the above technical solutions, which will not be elaborated here.
[0045] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application on the basis of several embodiments provided by the present application to obtain other embodiments, and none of these embodiments exceeds the protection scope of the present application.
[0046] The above specific implementation manners have further elaborated the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only the specific implementation manners of the embodiments of the present application, and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application shall be included in the protection scope of the embodiments of the present application.
