[0002] In key sectors such as power and transportation, environmental monitoring is a core component in ensuring the stable operation and safe operation of equipment. As the power and transportation sectors transform towards "unmanned and intelligent" systems, the demand for "multi-parameter, high-precision, and low-maintenance" environmental monitoring is becoming increasingly urgent. This necessitates multi-faceted environmental monitoring, which will utilize multi-element environmental monitoring sensors.

[0003] Existing multi-element environmental monitoring sensors cannot effectively cope with complex environmental conditions. The sensors are easily affected by the external environment, resulting in excessively high or low temperatures, which affects the working state of the sensors and leads to a decrease in monitoring accuracy. Utility Model Content

[0004] The purpose of this application is to provide a multi-element environmental monitoring sensor that can regulate the sensor's operating temperature according to its working conditions, preventing the sensor from experiencing excessively high or low temperatures due to external environmental factors. This allows the sensor to effectively cope with complex environmental conditions and prevents environmental factors from affecting the sensor's monitoring accuracy. It solves the problem that existing multi-element environmental monitoring sensors cannot effectively cope with complex environmental conditions, and are easily affected by external environmental factors, resulting in excessively high or low temperatures that affect the sensor's working state and reduce its monitoring accuracy.

[0005] The multi-element environmental monitoring sensor provided in this application adopts the following technical solution: The multi-element environmental monitoring sensor includes a sensor housing. A detection component is installed inside the sensor housing. The detection component includes a core monitoring unit. A probe is provided at the front end of the core monitoring unit. A control motherboard is fixedly installed at the rear end of the detection component. The control motherboard is electrically connected to the core monitoring unit. A temperature control component is provided inside the sensor housing. The temperature control component includes a thermoelectric cooler and a heating element. The thermoelectric cooler and heating element are fixedly installed on the outer surface of the middle part of the core monitoring unit. The thermoelectric cooler and heating element are electrically connected to the control motherboard. A cleaning component is provided inside the sensor housing. The cleaning component includes a cleaning motor. A cleaning brush is fixedly installed at one end of the output shaft of the cleaning motor. The cleaning motor is located on one side of the probe. A cleaning cotton on one side of the cleaning brush is slidably connected to the outer surface of one end of the probe. The cleaning motor is electrically connected to the control motherboard.

[0006] By adopting the above technical solution, the detection components can realize multi-element environmental monitoring, the control motherboard can coordinate the operation of each component, and adjust the temperature of the core monitoring unit by cooling the semiconductor cooling chip or heating the heating chip according to the temperature of the core monitoring unit, so as to avoid the core monitoring unit from being affected by excessively high or low temperature. The cleaning motor drives the cleaning brush to rotate and clean the probe head, preventing the surface of the probe head from being affected by dirt and affecting the monitoring accuracy. In summary, the sensor monitoring accuracy is improved.

[0007] Preferably, the semiconductor cooling chip and the heating chip are fixedly disposed on the front and rear outer surfaces and the left and right outer surfaces of the core monitoring unit, respectively.

[0008] By adopting the above technical solution, the semiconductor cooling chip and the heating chip are fixed to the front and rear outer surfaces and the left and right outer surfaces of the core monitoring unit, respectively. Through the symmetrical arrangement of the semiconductor cooling chip and the heating chip, the cooling effect of the semiconductor cooling chip and the heating effect of the heating chip can be balanced to regulate the temperature of the core monitoring unit, avoid local temperature anomalies in the core monitoring unit, and further ensure that the core monitoring unit is always at a suitable working temperature, maintain a stable working state, and ensure monitoring accuracy.

The heat dissipation fins can increase the heat dissipation area, and the heat pipes can promote the rapid transfer of heat, effectively improving the heat dissipation efficiency of the thermoelectric cooler during operation. This avoids the thermoelectric cooler from affecting the cooling effect due to its own heat accumulation, ensuring that the thermoelectric cooler can stably cool the core monitoring unit and guarantee the temperature stability of the core monitoring unit.

A detection hole is provided at one end of the dustproof cover, and the position of the detection hole corresponds to the position of the detection head.

[0012] By adopting the above technical solution, a dustproof component is installed at one end of the sensor housing. The dustproof cover can prevent a large amount of external dust from entering the sensor housing, avoiding dust adhering to the surface of internal components such as the detection component and control motherboard and affecting their operation. The opening position of the detection hole corresponds to the detection head, so it does not affect the normal environmental detection of the detection head. While preventing dust, it ensures the normal monitoring function of the sensor and reduces the interference of dust on the monitoring accuracy.

[0016] By adopting the above technical solution, a baffle is set at the tail end of the positioning card. The baffle can restrict the installation position of the core monitoring unit, preventing the core monitoring unit from being installed too deep during installation or use, and further ensuring the positioning accuracy of the core monitoring unit inside the sensor housing.

[0017] Preferably, a plurality of positioning plates are fixedly installed on the outer surface of the core monitoring unit near the front end. A positioning ring is provided on one side of the positioning plate. The positioning ring abuts against the plurality of positioning plates.

[0018] By adopting the above technical solution, when the dust cover is installed on the sensor housing, the positioning ring can enter the interior of the sensor housing and abut against multiple positioning plates. With the baffle at the end of the positioning card, the position of the core monitoring unit inside the sensor housing can be further fixed, preventing the core monitoring unit from shifting inside the sensor housing.

[0019] Preferably, a threaded connecting ring is fixedly provided on one side of the dust cover, a fixing ring is threadedly connected to the outer surface of the middle part of the threaded connecting ring, and a filter cover is fixedly provided at one end of the fixing ring.

[0020] By adopting the above technical solution, the filter cover can filter dust and impurities in the air, preventing dust from adhering to the surface of the probe and affecting monitoring. It can also further prevent dust and impurities from entering the interior of the sensor housing through the probe hole. The filter cover can be easily disassembled through the threaded connection between the threaded connecting ring and the fixing ring, making it convenient to clean or replace the filter cover.

[0021] Preferably, an extension frame is provided between the core monitoring unit and the probe head. The extension frame is fixedly installed at the front end of the core monitoring unit, the probe head is fixedly installed at one end of the extension frame, the cleaning motor is fixedly installed on a fixing plate on one side of the extension frame, and the probe head extends through the extension frame and through the probe hole to the outside of the sensor housing.

Furthermore, the probe head extends to the outside of the sensor housing via the extension frame, further preventing the temperature inside the sensor housing from affecting the accuracy of the probe head's monitoring of the external ambient temperature. At the same time, it can prevent the temperature generated by the semiconductor cooling chip and heating chip during operation from affecting the probe head, enabling the probe head to accurately monitor the external ambient temperature.

[0023] In summary, this application includes at least one of the following beneficial technical effects: This multi-element environmental monitoring sensor regulates the temperature of the core monitoring unit by using a semiconductor cooling chip for cooling or a heating chip for heating, keeping the core monitoring unit at a suitable operating temperature.

[0036] The implementation principle of this application embodiment is as follows: The control motherboard 3 is electrically connected to the core monitoring unit 201. The core monitoring unit 201 realizes multi-element environmental monitoring through the front-end probe 202. When the control motherboard 3 detects that the temperature of the core monitoring unit 201 is too high, it controls the semiconductor cooling chip 401 in the temperature control component 4 to work, so that the semiconductor cooling chip 401 cools the core monitoring unit 201. The heat generated by the semiconductor cooling chip 401 is quickly dissipated through multiple heat dissipation fins 11 and heat pipes 12. When the temperature of the core monitoring unit 201 is too low, the control motherboard 3 controls the heating chip 402 to work, so that the heating chip 402 heats the core monitoring unit 201, ensuring that the core monitoring unit 201 is at a suitable working temperature. When it is necessary to clean the dust or other impurities that affect the operation of the probe 202 from the surface of the probe 202, the control motherboard 3 can periodically control the cleaning motor 701 in the cleaning component 7 to work. The cleaning motor 701 drives the cleaning brush 702 to rotate, so that the cleaning brush 702 cleans the surface of the probe 202. Wipe and clean to remove attached stains. The dust cover 601 at one end of the sensor housing 1 can block most of the external dust from entering the interior. The filter cover 603 on one side of the dust cover 601 filters dust and impurities in the air, preventing dust and impurities in the air from directly adhering to the detector head 202 and affecting the monitoring accuracy of the detector head 202. When the filter cover 603 becomes clogged due to filtering too much dust and impurities, rotate the fixing ring 605 to remove the fixing ring 605 from the threaded connection ring 604, and clean or replace the filter cover 603. When it is necessary to repair the core monitoring unit 201, rotate the rod dust cover 601 to remove the dust cover 601 through the threaded connection between the dust cover 601 and the sensor housing 1. When the dust cover 601 is removed, the positioning ring 10 will be removed from the sensor housing 1, releasing the positioning ring 10 from the positioning plate 9.
