[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example 1

[0031] This example discloses a modular water tank, see Figures 1 to 7 , including a plurality of spliced ​​water tanks 1, a hole 2 is arranged on the side of the water tank 1, the pre-buried shape of the hole 2 matches the thread of the steel plate bolt, a boss 3 or a limiting slot 4 for accommodating the boss 3 is arranged on the other side of the water tank 1, and a water inlet 5 and a water outlet 6 are arranged on the water tank 1.

[0032] A screw motor 7 is installed outside the water tank 1, a screw 8 is installed on the rotation power output shaft of the screw motor 7, a magnetic nut 9 matching with the screw 8 is installed on the screw 8, and a magnetic cleaning brush 10 adsorbed on the magnetic nut 9 is arranged in the water tank 1.

[0033] A plurality of rotating nozzles 11 are installed in the water tank 1. The rotating nozzles 11 include a plurality of nozzles 12 arranged along the circumference of the rotating nozzles 11. The rotating nozzles 11 penetrate the waterproof box through a rotating shaft 13 to connect to a rotating assembly. The rotating assembly includes a rotating motor 14. A driving gear 15 is installed on the rotating power output shaft of the rotating motor 14. The driving gear 15 is transmission-connected to a driven gear 16. The rotating shaft 13 is correspondingly installed on the driven gear 16.

[0034] A laser liquid level detection module for detecting the liquid level in the water tank is installed in the water tank 1. The laser liquid level detection module includes a laser 17 and a collimating lens 18 installed in sequence along the incident direction of the light source, and an imaging lens 19 and a photoelectric position sensor 20 installed in sequence along the reflection direction of the light source; the voltage signal output end of the photoelectric position sensor 20 is connected to the DSP processor, and the signal output end of the DSP processor is connected to the display and the alarm.

[0035] The laser 17 includes a He-Ne laser; the photoelectric position sensor 20 includes a PSD-400-LC; and the DSP processor includes a TMS320F28335 processor.

[0036] A black light-shielding tube 21 is installed outside the imaging lens 19 and the photoelectric position sensor 20. The length of the black light-shielding tube 21 is not less than the distance between the imaging lens 19 and the photoelectric position sensor 20. The inner diameter of the black light-shielding tube 21 is not less than the diameter of the photoelectric position sensor 20. The diameters of the imaging lens 19 and the photoelectric position sensor 20 are the same.

[0037] During operation, multiple water tanks 1 are installed on the RV by using steel plate bolts in the pre-set holes 2, and the side bosses 3 of the water tanks 1 cooperate with the limit slots 4 to achieve close splicing between the water tank modules, forming water storage spaces with different capacity requirements. This ensures that the positioning between adjacent water tanks is stable and convenient for quick disassembly and assembly. During the operation of the cleaning component, the lead screw motor 7 drives the lead screw 8 to rotate when it is working, and the magnetic nut 9 that cooperates with it moves on the lead screw 8 accordingly, and then the magnetic nut 9 absorbs the magnetic cleaning brush 10, driving the magnetic cleaning brush 10 to reciprocate on the inner wall of the water tank 1, thereby effectively cleaning the inner wall of the water tank 1. At the same time, the rotating motor 14 drives the driving gear 15 to rotate, and the driven gear 16 drives the rotating nozzle 11 on the rotating shaft 13 to rotate through the gear transmission mechanism. The water flow sprayed by the nozzle 12 can achieve 360° flushing without dead angles, ensuring that the inside of the water tank is thoroughly cleaned. During the operation of the laser liquid level detection module, a laser beam is emitted by a He-Ne laser 17, projected onto the water surface through a collimating lens 18, and then reflected by the water surface and focused on a photoelectric position sensor 20 through an imaging lens 19. The photoelectric position sensor 20 converts the received light signal into a voltage signal, transmits it to the DSP processor for calculation and analysis, and obtains accurate water level height data. When the water level changes, the DSP processor will display the real-time liquid level through a display, and when the water level reaches a preset value, an alarm will be triggered to realize intelligent water level monitoring and early warning. In order to improve the accuracy of liquid level detection and avoid external light interference, a black light shielding tube 21 is specially added to the periphery to ensure that only the laser beam reflected from the water surface is received, thereby ensuring the accuracy of liquid level measurement. In summary, the modular water tank of the utility model integrates multiple functions such as modular design, automatic cleaning, all-round spray cleaning, and high-precision liquid level detection, which greatly improves the practicality and intelligence level of the water tank, and is conducive to achieving efficient, energy-saving, and safe water resource management.
