[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of this application.

Therefore, they should not be construed as limitations on this application. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features.

[0026] To illustrate the technical solutions provided in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0027] Please refer to the following: Figure 1 and Figure 2 The liquid level monitoring device provided in this application includes a liquid storage tank 100 and a liquid detection element 200. The inner wall of the liquid storage tank 100 has a triangular prism structure 101. The liquid detection element 200 is disposed outside the liquid storage tank 100 and close to the triangular prism structure 101. The liquid detection element 200 includes a transmitting end 201 and a receiving end 202. The transmitting end 201 is used to transmit a signal to the triangular prism structure 101, and the receiving end 202 is used to receive the signal reflected back by the triangular prism structure 101.

[0028] Compared with the prior art, the liquid level monitoring device provided in this application, through the arrangement of a triangular prism structure 101 and a liquid detection element 200, can achieve effective monitoring of liquid. When there is no liquid at the height corresponding to the installation position of the liquid detection element 200 in the storage tank 100, the signal emitted by the transmitter 201 will be reflected back inside the triangular prism structure 101 and received by the receiver 202. When there is liquid at the height corresponding to the installation position of the liquid detection element 200 in the storage tank 100, due to the presence of liquid, the signal emitted by the transmitter 201 will pass through the triangular prism structure 101 and be absorbed by the liquid, and the receiver 202 will not receive the signal. Therefore, by determining whether the receiver 202 receives a signal, it can be determined whether there is liquid at the height corresponding to the installation position of the liquid detection element 200 in the storage tank 100, thereby achieving effective monitoring of liquid and improving monitoring accuracy. At the same time, the liquid detection element 200 is located outside the storage tank 100 and will not be corroded by liquid, thus improving the service life of the liquid detection element 200.

[0029] In one embodiment, please refer to [the relevant documentation / reference]. Figure 2 , Figure 3 and Figure 8 The outer wall of the liquid storage tank 100 is provided with a groove 102, and the position of the groove 102 is opposite to the position of the triangular prism structure 101.

[0030] In this embodiment, by setting the groove 102, the propagation path of the signal emitted by the liquid detection element 200 on the outer wall of the liquid storage tank 100 is shortened, the signal attenuation is reduced, and the efficiency of signal transmission is improved.

[0031] In one embodiment, the cross-sectional shape of the groove 102 is rectangular or V-shaped.

[0032] In this embodiment, the rectangular or V-shaped groove 102 design makes the signal reflection within the groove 102 more regular, enhancing the signal transmission effect and improving the accuracy of liquid monitoring.

[0033] In one embodiment, the triangular prism structure 101 is in the shape of a regular triangular prism.

[0034] The design of the regular triangular prism structure makes the signal reflection inside more uniform, avoiding signal loss caused by structural irregularities, thereby improving the stability and reliability of monitoring.

[0035] In one embodiment, the surface of the triangular prism structure 101 is provided with a reflective layer to enhance the reflection effect of the signal emitted by the transmitter 201. The reflective layer can be made of a highly reflective metal or plating, such as aluminum, silver, or a silver plating layer, to ensure that the signal can be effectively reflected back to the receiver 202. This design improves the accuracy and reliability of liquid monitoring.

[0036] In one embodiment, the surface of the triangular prism structure 101 is further provided with an anti-corrosion layer. This anti-corrosion layer protects the triangular prism structure 101 from liquid erosion and extends its service life. The material of the anti-corrosion layer can be a plastic, rubber, or special coating with good corrosion resistance. These materials can effectively isolate the triangular prism structure 101 from direct contact with the liquid, preventing corrosion caused by long-term immersion in the liquid, thereby ensuring the stability and durability of the liquid level monitoring device.

[0037] In one embodiment, the triangular prism structure 101 is integrally formed with the liquid storage tank 100. This design not only enhances the structural stability but also simplifies the manufacturing process and improves production efficiency. The seamless connection between the triangular prism structure 101 and the liquid storage tank 100 avoids signal leakage or structural loosening caused by improper assembly, ensuring the accuracy and long-term stability of liquid level monitoring. Furthermore, the integral design helps reduce material waste and processing costs, making the liquid level monitoring device more economical and practical.

[0038] In one embodiment, the liquid storage tank 100 is made of a transparent or semi-transparent material, such as plexiglass or transparent plastic, so that the operator can visually observe the liquid condition inside the tank 100. At the same time, the choice of transparent or semi-transparent material will not affect the signal transmission and reception of the liquid detection element 200.

[0039] In one embodiment, the liquid detection element 200 is any one of an infrared detector, an ultrasonic detector, or a radar detector.

[0040] Infrared detectors, ultrasonic detectors, and radar detectors all feature high precision and sensitivity, enabling them to quickly and accurately detect changes in the liquid within the storage tank 100. Infrared detectors determine the presence and height of the liquid by measuring its infrared radiation; ultrasonic detectors measure the distance to the liquid by emitting ultrasonic waves and receiving their reflected waves; and radar detectors utilize the characteristics of radar waves for non-contact liquid monitoring. The choice of these detectors depends on the specific application scenario and monitoring requirements, but all can meet the requirements for real-time liquid monitoring, ensuring the accuracy and reliability of the monitoring results.

[0041] In one embodiment, the liquid level monitoring device further includes a controller electrically connected to the liquid detection element 200. The controller is used to acquire signals transmitted by the receiver 202 and determine the liquid state in the storage tank 100 based on the signals. The controller can be connected to an alarm device. When an abnormal liquid state is detected, such as a liquid level that is too low or too high, the controller triggers the alarm device to issue an alarm, reminding the operator to handle the situation promptly.

[0042] In one embodiment, please refer to [the relevant documentation / reference]. Figure 4 , Figure 5 and Figure 9 The liquid level monitoring device also includes a frame 300, a liquid detection element 200 mounted on the frame 300, and a distance between the liquid storage tank 100 and the liquid detection element 200.

[0043] In this embodiment, the frame 300 serves as the main support structure of the liquid level monitoring device. Its robust and durable design ensures the stability and reliability of the liquid detection element 200 after installation. The liquid detection element 200, through a reasonable installation layout, is tightly integrated with the frame 300, facilitating adjustment and calibration while guaranteeing detection accuracy. Simultaneously, the spacing between the storage tank 100 and the liquid detection element 200 avoids corrosion and contamination issues that might arise from direct liquid contact with the detection element, while ensuring effective transmission of the detection signal. This improves the accuracy and sensitivity of liquid monitoring. Furthermore, the movement of the storage tank 100 does not interfere with the liquid detection element 200, extending its service life. This design enables the liquid level monitoring device to operate stably in various complex environments, providing reliable assurance for liquid monitoring within the storage tank 100.

[0044] In one embodiment, see Figure 7 The triangular prism structure 101 is located at the bottom of the liquid storage tank 100.

[0045] In this embodiment, the triangular prism structure 101 is set at the bottom of the liquid storage tank 100. When the receiving end 202 of the liquid detection element 200 can receive the signal emitted by the transmitting end 201, it indicates that the liquid in the liquid storage tank 100 has reached the minimum liquid level. At this time, it is necessary to replenish the liquid in time to avoid the liquid storage tank 100 being empty and affecting the normal operation of the equipment.

[0046] In one embodiment, please refer to [the relevant documentation / reference]. Figure 7 and Figure 9 The frame 300 is provided with a positioning hole 301, and the liquid storage tank 100 is provided with a positioning post 103, which cooperates with the positioning hole 301.

[0047] In this embodiment, the positioning post 103 and the positioning hole 301 are designed to ensure that the liquid storage tank 100 can be stably installed on the frame 300, avoiding monitoring errors caused by unstable installation. This also ensures the accuracy of the positional relationship between the liquid detection element 200 and the triangular prism structure 101, improving the precision and reliability of liquid monitoring. Furthermore, the positioning hole 301 and the positioning post 103 facilitate the disassembly and replacement of the liquid storage tank 100, improving the maintenance efficiency of the liquid level monitoring device.

[0048] In one embodiment, please refer to [the relevant documentation / reference]. Figure 7 , Figure 9 As shown in Figure 10, the open end of the liquid storage tank 100 is provided with a tank cover 400. The edge of the tank cover 400 that contacts the liquid storage tank 100 is provided with multiple protruding structures 401. The protruding structures 401 are used to create an air flow gap between the liquid storage tank 100 and the tank cover 400.

[0049] In this embodiment, by providing the protruding structure 401, a certain gap is created between the lid 400 and the liquid storage tank 100, thereby ensuring airflow between the liquid storage tank 100 and the lid 400. This design helps maintain airflow within the liquid storage tank 100, ensuring its normal operation. Furthermore, the protruding structure 401 also increases the tension between the lid 400 and the liquid storage tank 100, improving the stability of the lid 400.

[0050] In another embodiment of this application, referring to Figure 11, a capacitive sensor 107 is provided on the bottom surface inside the liquid storage tank 100, and a signal control board 108 is provided on the bottom surface outside the liquid storage tank 100. The signal control board 108 is electrically connected to the capacitive sensor 107. The capacitive sensor 107 is used to detect changes in the liquid level inside the liquid storage tank 100. When there is no liquid covering the surface of the capacitive sensor 107, its capacitance value changes, and the signal control board 108 detects the liquid level height based on the change in the capacitance value of the capacitive sensor 107. This design provides another means of monitoring the liquid level inside the liquid storage tank 100, increasing the versatility and flexibility of the liquid level monitoring device. The capacitive sensor 107 has the characteristics of high precision and high sensitivity, and can reflect changes in the liquid level in real time and accurately, ensuring the accuracy of the monitoring results. At the same time, the electrical connection design between the capacitive sensor 107 and the signal control board 108 makes signal transmission and processing more efficient and reliable, improving the overall performance of the liquid level monitoring device.

[0051] In another embodiment of this application, please refer to [the relevant document / reference]. Figure 1 and Figure 3 The triangular prism structure 101 is disposed on the side of the liquid storage tank 100, and the height direction of the triangular prism structure 101 is consistent with the height direction of the liquid storage tank 100.

[0052] In this embodiment, the triangular prism structure 101 is disposed on the side of the liquid storage tank 100, which can monitor a certain preset height in the liquid storage tank 100.

[0053] For example, the liquid detection element 200 is set at the highest water level position of the corresponding liquid storage tank 100. When the receiver 202 of the liquid detection element 200 can receive the signal emitted by the transmitter 201, it indicates that the liquid in the liquid storage tank 100 has not yet reached the highest water level position, and liquid can continue to be added to the liquid storage tank 100; when the receiver 202 of the liquid detection element 200 cannot receive the signal emitted by the transmitter 201, it indicates that the highest water level position in the liquid storage tank 100 has been covered by liquid, and liquid should be stopped from being added to the liquid storage tank 100.

[0054] For example, the liquid detection element 200 is positioned at the lowest water level of the corresponding storage tank 100. When the receiver 202 of the liquid detection element 200 cannot receive the signal emitted by the transmitter 201, it indicates that the lowest water level in the storage tank 100 is still covered by liquid, and the storage tank 100 can continue to be used. When the receiver 202 of the liquid detection element 200 can receive the signal emitted by the transmitter 201, it indicates that the lowest water level in the storage tank 100 is no longer covered by liquid. At this time, liquid needs to be replenished to the storage tank 100 in a timely manner to prevent the storage tank 100 from becoming empty, thus ensuring the normal use of the storage tank 100.

[0055] In one embodiment, multiple liquid detection elements 200 can be arranged along the height direction of the triangular prism structure 101 to monitor liquid levels at different heights within the storage tank 100. By using multiple liquid detection elements 200, the distribution of liquid within the storage tank 100 can be more accurately determined, improving the accuracy and reliability of liquid monitoring. For example, by placing one liquid detection element 200 at the top, middle, and bottom of the storage tank 100, changes in the liquid level within the tank can be monitored in real time, preventing adverse effects from excessive or insufficient liquid levels. Simultaneously, the arrangement of multiple liquid detection elements 200 increases monitoring redundancy; even if one liquid detection element 200 fails, the others can still operate normally, ensuring continuous and stable monitoring. This design makes the liquid level monitoring device more reliable and practical, enabling its widespread application in various situations requiring liquid monitoring.

[0056] In one embodiment, see Figure 5 The frame 300 has a receiving cavity 302, and the liquid storage tank 100 is placed in the receiving cavity 302.

[0057] In this embodiment, by providing the receiving cavity 302, the liquid storage tank 100 can be placed more stably, avoiding monitoring errors caused by the shaking of the liquid storage tank 100. The design of the receiving cavity 302 can also limit the liquid storage tank 100, preventing it from shifting during operation, ensuring the accuracy of the relative positional relationship between the liquid detection element 200 and the triangular prism structure 101, and improving the accuracy and reliability of liquid monitoring. At the same time, the receiving cavity 302 also facilitates the installation and disassembly of the liquid storage tank 100, improving the maintenance efficiency of the liquid level monitoring device. In addition, the receiving cavity 302 can also protect the liquid storage tank 100 from interference and damage from the external environment, extending the service life of the liquid storage tank 100.

[0058] In one embodiment, please refer to [the relevant documentation / reference]. Figure 2 and Figure 5The cavity 302 is provided with a positioning protrusion 303, and the liquid storage tank 100 is provided with a first positioning groove 104, which cooperates with the positioning protrusion 303.

[0059] In this embodiment, the positioning protrusion 303, in cooperation with the first positioning groove 104, can fix the position of the liquid storage tank 100 in the receiving cavity 302, preventing it from shaking or shifting during operation. This design not only improves the stability and accuracy of the liquid level monitoring device but also makes the installation of the liquid storage tank 100 simpler and faster. Simultaneously, the cooperation between the positioning protrusion 303 and the first positioning groove 104 also provides a guiding function, helping to quickly find the correct disassembly position when disassembling the liquid storage tank 100, thus improving the maintenance efficiency of the liquid level monitoring device. Furthermore, the design of the positioning protrusion 303 and the first positioning groove 104 can be adjusted according to actual needs to accommodate liquid storage tanks 100 of different specifications and sizes, improving the versatility and flexibility of the liquid level monitoring device.

[0060] In one embodiment, please refer to [the relevant documentation / reference]. Figure 2 and Figure 4 The cavity 302 is provided with an elastic buckle 304, and the liquid storage tank 100 is provided with a second positioning groove 105, and the elastic buckle 304 is engaged in the second positioning groove 105.

[0061] In this embodiment, the quick installation and removal of the liquid storage tank 100 can be achieved by cooperating with the elastic buckle 304 and the second positioning groove 105. The operator only needs to align the second positioning groove 105 on the liquid storage tank 100 with the elastic buckle 304 in the receiving cavity 302 and press gently to complete the installation. Disassembly is similarly simple; just press the elastic buckle 304 to easily remove the liquid storage tank 100. This design not only simplifies the installation and disassembly process and improves work efficiency, but also helps ensure the stability and reliability of the liquid storage tank 100 after installation. Simultaneously, the cooperation between the elastic buckle 304 and the second positioning groove 105 also provides a certain buffering effect, which can reduce the vibration and impact of the liquid storage tank 100 during operation to a certain extent, extending the service life of the liquid storage tank 100 and the liquid level monitoring device. This design makes the liquid level monitoring device easier to maintain and manage, providing a more convenient and reliable solution for various applications requiring liquid monitoring.

[0062] In one embodiment, see Figure 6The elastic buckle 304 includes a buckle body 341, an elastic element 342, and a fixing element 343. The elastic element 342 is disposed between the buckle body 341 and the fixing element 343. The bottom of the receiving cavity 302 is provided with a clearance hole 321, and the buckle body 341 is located in the clearance hole 321. The fixing element 343 is connected to the frame 300. When the elastic element 342 is compressed, the buckle body 341 is flush with the bottom surface of the receiving cavity 302. When the elastic element 342 is extended, the buckle body 341 protrudes from the bottom surface of the receiving cavity 302 and is engaged in the second positioning groove 105.

[0063] This design makes the elastic buckle 304 more flexible and reliable in fixing and releasing the liquid storage tank 100. When the elastic element 342 is compressed, the buckle body 341 is flush with the bottom surface of the receiving cavity 302, without causing any obstruction, facilitating the smooth insertion of the liquid storage tank 100. When the elastic element 342 is extended, the buckle body 341 protrudes from the bottom surface of the receiving cavity 302 and is tightly engaged in the second positioning groove 105 on the liquid storage tank 100, thereby achieving a stable fixing effect. In addition, the setting of the clearance hole 321 also cleverly solves the position problem of the buckle body 341 in the receiving cavity 302, ensuring the normal operation of the elastic buckle 304 and avoiding interference with other parts of the receiving cavity 302. This structural design not only improves the overall performance of the liquid level monitoring device, but also brings users a more convenient and efficient user experience.

[0064] In one embodiment, please refer to [the relevant documentation / reference]. Figure 1 and Figure 2 The outer side of the liquid storage tank 100 is provided with a handle 106.

[0065] In this embodiment, by providing a handle 106, operators can more easily move and transport the liquid storage tank 100, improving operational convenience. The handle 106 is typically designed with robust and durable materials to ensure it will not be damaged during transport and can also withstand a certain weight. The shape and size of the handle 106 are also rationally designed according to the size of the liquid storage tank 100 and the usage scenario to ensure that operators can comfortably grip and easily move the liquid storage tank 100. This design makes the liquid level monitoring device more user-friendly in daily use and maintenance, improving work efficiency and operational experience.

[0066] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
