[0030] In related technologies, as the need for cost reduction in production volume increases, the structure of cleaning tanks is becoming increasingly larger. Temperature monitoring cannot provide feedback on the temperature distribution throughout the entire tank.

[0031] To address the aforementioned issues, this invention provides a tank cover and a cleaning device that optimizes temperature monitoring by monitoring the temperature of the liquid at different depths.

[0037] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0038] The following describes in detail the overall structure, working principle, and technical effects of the trough cover 10 and cleaning device 1 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0039] Please see Figure 1 and Figure 2 This utility model provides a tank cover 10, applied to a cleaning device 1, for monitoring the temperature of the medicinal solution at different depths within the cleaning device 1, thereby optimizing temperature monitoring. The cleaning device 1 includes a tank body 30 and a tank cover 10. The tank body 30 is used to contain the medicinal solution, and the tank cover 10 mates with the open end of the tank body 30. Optionally, the tank body 30 is made of stainless steel, specifically SUS316, to prevent corrosion from the alkaline medicinal solution within it.

[0040] The tank cover 10 includes a cover plate 100 and a temperature measuring component 300. Correspondingly, the cover plate 100 is used to engage with the open end of the tank body 30. The temperature measuring component 300 is rotatably connected to the cover plate 100 and is used to switch between a first position 1000 and a second position 3000. It should be noted that when the temperature measuring component 300 is in the first position 1000, the temperature measuring component 300 can measure the temperature of the liquid medicine at different depths in the tank body 30. When the temperature measuring component 300 is in the second position 3000, the temperature measuring component 300 can be separated from the liquid medicine in the tank body 30.

[0041] In practical applications, when the cover plate 100 and the tank 30 are in conjunction, if it is necessary to monitor the temperature of the liquid medicine in the tank 30, the temperature measuring component 300 rotates from the second position 3000 to the first position 1000 to contact and measure the temperature of the liquid medicine at different depths; if it is not necessary to monitor the temperature of the liquid medicine in the tank 30, the temperature measuring component 300 rotates from the first position 1000 to the second position 3000, separates from the liquid medicine in the tank 30, and resets accordingly.

[0042] In some embodiments, to more comprehensively monitor the temperature distribution within the entire tank 30, at least two temperature sensing components 300 are provided, spaced apart from each other on the cover plate 100. Optionally, four temperature sensing components 300 are provided, with two spaced apart along the width of the cover plate 100 and the other two spaced apart along the length of the cover plate 100. Alternatively, the inner cavity of the tank 30 can be divided into four regions, with three temperature sensing components 300 provided in each of the four regions.

[0043] Please see Figure 2The temperature measuring assembly 300 includes a rotating arm 310 and at least two temperature measuring elements 330. The rotating arm 310 is rotatably connected to the cover plate 100. The at least two temperature measuring elements 330 are spaced apart along the axial direction of the rotating arm 310. It is easy to understand that when the rotating arm 310 rotates the temperature measuring elements 330 to the first position 1000, each temperature measuring element 330 monitors the temperature of the liquid medicine at its corresponding depth. When the rotating arm 310 rotates the temperature measuring elements 330 to the second position 3000, each temperature measuring element 330 separates from the liquid medicine. Optionally, the number of temperature measuring elements 330 is three, measuring the temperature at high, medium, and low positions of the liquid medicine, respectively.

[0044] To further monitor temperature changes at different locations inside the tank 30 from top to bottom, when the temperature sensing component 300 is in the first position 1000, the rotating arm 310 is perpendicular to the cover plate 100. Correspondingly, when the temperature sensing component 300 is in the second position 3000, the rotating arm 310 is parallel to the cover plate 100. Based on this, the temperature sensing component 300 can switch between the first position 1000 and the second position 3000 by rotating 90 degrees clockwise or counterclockwise.

[0045] Because PVDF (polyvinylidene fluoride) exhibits excellent resistance to most chemicals and can withstand the corrosive effects of various acids, alkalis, salts, and organic solvents, the rotating arm 310 is made of PVDF. To improve the stability and smoothness of the rotation switching process, the temperature sensing assembly 300 also includes a rotating shaft 370. The rotating arm 310 rotates with the cover plate 100 via the rotating shaft 370. Optionally, the rotating shaft 370 is also made of PVDF.

[0046] Additionally, the temperature sensing element 330 mounted on the rotating arm 310 can be a thermometer or a temperature sensor. When using a thermometer, the operator can read the value through the scale on the thermometer. Optionally, the thermometer can resolve temperature changes as small as 0.1°C. When using a temperature sensor, the sensor can convert the temperature signal into an electrical signal, which is then transmitted to the PLC control system.

[0047] To further improve the ease of operation for storing and placing the rotating arm 310, the temperature measuring assembly 300 also includes a drive element 350. The drive element 350 is connected to the cover plate 100 and the rotating arm 310, and is used to drive the rotating arm 310 to rotate relative to the cover plate 100. Additionally, it should be noted that the drive element 350 can also be connected to the aforementioned PLC control system, under which the rotating arm 310 can be automatically extended or retracted. Optionally, the drive element 350 can be a hydraulic or pneumatic drive to facilitate changing the position of the rotating arm 310 through simple extension and retraction movements.

[0048] Taking the cleaning device 1 provided by this utility model as an example, the working process and working principle of the cleaning device 1 are as follows:

[0049] The cover plate 100 is fitted into the tank body 30. Then, the PLC control system activates the temperature measurement mode, controlling the drive element 350 to extend, causing the rotating arm 310 to rotate from the second position 3000 to the first position 1000. At this time, each temperature measuring element 330 reads the temperature of the liquid at its corresponding height. After the test is completed, the PLC control system deactivates the temperature measurement mode and controls the drive element 350 to retract, causing the rotating arm 310 to rotate from the first position 1000 to the second position 3000.

[0050] In summary, this utility model provides a tank cover 10 and a cleaning device 1. The tank cover 10 includes a cover plate 100 and a temperature measuring component 300. The cover plate 100 is used to engage with the open end of the tank body 30. The temperature measuring component 300 is rotatably connected to the cover plate 100 and is used to switch between a first position 1000 and a second position 3000. It should be noted that when the temperature measuring component 300 is in the first position 1000, the temperature measuring component 300 can measure the temperature of the liquid medicine at different depths in the tank body 30. When the temperature measuring component 300 is in the second position 3000, the temperature measuring component 300 can be separated from the liquid medicine in the tank body 30. Based on the above, this utility model optimizes temperature monitoring by monitoring the temperature of the liquid medicine at different depths.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
