[0026] See also Figures 1 to 4 The utility model provides a temperature sensor for obtaining the temperature of a solution in a container. The temperature sensor includes a temperature sensor body 100, a protective sleeve 200, a sealing cover 300, a thermal detector 400 and a wire 500. The temperature sensor body 100 is mounted on the outer surface of the container side wall 10 and includes a signal processor; one end of the protective sleeve 200 is connected to the temperature sensor body 100, and the other end extends from the outside of the container to the inside of the container; the sealing cover 300 is sealed and mounted on the end of the protective sleeve 200 away from the temperature sensor body 100; the thermal detector 400 is mounted inside the sealing cover 300; one end of the wire 500 is electrically connected to the thermal detector 400, and the other end extends along the inner cavity of the protective sleeve 200 to the signal processor and is electrically connected to the signal processor. In the temperature sensor of the present application, when testing, the thermal detector 400 is extended below the liquid surface of the test solution, and the sealing cover 300 is sealed and connected to the protective cover 200 to effectively prevent the test solution from evaporating into the protective cover 200 and the sealing cover 300 to corrode the wire 500 and the thermal detector 400; further, the temperature sensor body 100 is arranged outside the container, which can reduce corrosion to the temperature sensor body 100.

[0027] See also Figure 1 and Figure 2In one embodiment, the sealing cover 300 is sleeved with the protective sleeve 200. Specifically, a step is provided on the side wall of the sealing cover 300, and one end of the opening of the sealing cover 300 extends into the protective sleeve 200, where the step abuts the opening of the protective sleeve 200. For example, the protective sleeve 200 and the sealing cover 300 are made of corrosion-resistant stainless steel. Furthermore, thermal grease 310 is filled in the sealing cover 300, and the thermal grease 310 is wrapped around the thermal detector 400 to reduce the air gap around the thermal detector 400, enhance the heat conduction performance, and ensure the accuracy of the measurement results.

[0028] In this embodiment, an anti-corrosion insulating layer 600 is provided on the outer walls of the protective sleeve 200 and the sealing cover 300. The anti-corrosion insulating layer 600 at least seals and covers the docking position of the protective sleeve 200 and the sealing cover 300 to improve the anti-corrosion effect of the protective sleeve 200 and the sealing cover 300. Furthermore, the anti-corrosion insulating layer 600 covers the outer walls of the entire protective sleeve 200 and the entire sealing cover 300 to better protect the protective sleeve 200 and the sealing cover 300 and improve the anti-corrosion effect. There is no limitation on the setting method of the anti-corrosion insulating layer 600 here. For example, an insulating anti-corrosion polymer material sleeve with certain heat shrinkage properties is sheathed on the outer side of the protective sleeve 200 and the sealing cover 300. The sleeve is closed at one end and open at the other end of the sealing cover 300. After the sleeve is placed over the protective sleeve 200 and the sealing cover 300, the protective sleeve 200 and the sealing cover 300 are heated. The sleeve shrinks due to the heat and adheres tightly to the surface of the protective sleeve 200 and the sealing cover 300, forming an anti-corrosion insulating layer 600. In this application, the material of the anti-corrosion insulating layer 600 is not limited, as long as it can achieve the anti-corrosion and insulating functions.

[0029] See also Figure 1 、 Figure 3 and Figure 4In one embodiment, the portion of the protective cover 200 located outside the liquid surface is an inverted U-shaped structure. One side of the inverted U-shaped structure abuts the inner surface of the container sidewall 10, while the other side is fixedly connected to the outer surface of the container sidewall 10 via an adjustment device 700. The top of the inverted U-shaped structure abuts the top of the container sidewall 10, and the temperature sensor body 100 is fixedly connected to the end of the protective cover 200 located outside the container sidewall 10. In this embodiment, the adjustment device 700 includes a fixing bracket 710 and an adjustment bolt 720. The fixing bracket 710 is provided with a threaded hole that matches the adjustment bolt 720. The adjustment bolt 720 passes through the threaded hole in the fixing bracket 710 and abuts the outer surface of the container sidewall 10. Furthermore, due to heat exchange between the container sidewall 10 and the surrounding environment, local temperature differences may occur. To ensure accurate and stable temperature measurement, the end of the portion of the protective cover 200 located below the liquid surface is tilted away from the container sidewall 10. The temperature sensor of the present application has a simple structure and is easy to install. The position can be adjusted at will without the need for a bracket. In addition, the fixing bracket 710 is made of insulating material, which can achieve overall insulation of the temperature sensor and improve its service life.

[0030] See also Figure 1 、 Figures 3 to 6 In one embodiment, the temperature sensor body 100 further includes a housing 110 and a power supply (not shown) for providing electrical energy to the signal processor. The signal processor and the power supply are disposed within the housing 110, and the housing 110 is fixedly connected to the fixing bracket 710. Specifically, the housing 110 is provided with a mounting portion 111, and the fixing bracket 710 is provided with a groove 711 that cooperates with the protective cover 200. The temperature sensor body 100 is disposed on a side of the protective cover 200 facing away from the container side wall 10, and the fixing bracket 710 is disposed on a side of the protective cover 200 close to the container side wall 10. The mounting portion 111 and the fixing bracket 710 are fixedly connected by fasteners. Furthermore, in order to facilitate maintenance of the temperature sensor body 100, the temperature sensor body 100 and the fixing bracket 710 are detachably connected. For example, the fasteners include bolts and nuts. Both the mounting portion 111 and the fixing bracket 710 are provided with through holes for the bolts to pass through. The bolts pass through the mounting portion 111 and the fixing bracket 710 in sequence and are threadedly connected to the nuts, thereby securing the temperature sensor body 100 to the fixing bracket 710. In this embodiment, a rechargeable battery is used as the power source. In this application, there is no restriction on the type of battery, as long as it can provide power to the signal processor.

These sealing and locking connectors provide excellent sealing performance and a reliable mechanical locking mechanism, ensuring airtightness and watertightness when the wire 500 passes through the sealing interface, preventing the intrusion of contaminants and moisture, and effectively extending the life of the temperature sensor.

[0032] The present invention also provides a temperature monitoring device, comprising a controller and the aforementioned temperature sensor, the temperature sensor being communicatively connected to the controller to transmit the temperature of the test solution to the controller.

In this embodiment, the temperature control device comprises multiple temperature sensors, each mounted on a corresponding container and electrically connected to the controller, and the display device can simultaneously display the liquid temperatures measured by the multiple temperature sensors. Furthermore, the display device can be a human-computer interface, through which a temperature threshold of the test solution can be set. Furthermore, the temperature monitoring device further comprises multiple alarm devices, each electrically connected to the controller, with each alarm device corresponding to a temperature sensor. The type of alarm device is not limited herein; the alarm device can be any device capable of alerting an operator. For example, the alarm device can be a warning light. When the temperature of the test solution exceeds a set temperature threshold or a temperature sensor malfunctions, the warning light flashes or changes color to alert the operator to prompt repairs.

[0033] The temperature sensor provided by the present invention comprises a temperature sensor body including a signal processor, a thermal detector electrically connected to the signal processor via a wire, a protective sleeve disposed outside the wire, the thermal detector disposed within a sealing cover at the end of the protective sleeve, the protective sleeve and the sealing cover being sealed, an anti-corrosion insulating layer disposed on the outer walls of the protective sleeve and the sealing cover, the anti-corrosion insulating layer at least sealingly covering the docking position of the protective sleeve and the sealing cover, thereby reducing corrosion of the wire and the thermal detector by the test solution.
