[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 9 This application provides a fire truck water tank structure with self-cleaning function, including a water storage tank 1. The water storage tank 1 is made of corrosion-resistant and high-strength metal material and can store fire-fighting water for a long time. The water storage tank 1 is equipped with a cleaning component 2 to achieve automatic cleaning of the inner wall of the water tank.

[0027] The cleaning component 2 includes a top plate 21, which is bolted to the top of the water tank 1. A sealing gasket is provided at the bolt connection to ensure the airtightness of the water tank 1. The top plate 21 has two guide grooves 22 on both sides. The top of the top plate 21 is welded to a protective cover 213, which protects the internal components from external impacts and dust corrosion. There are two protective covers 213, and their positions correspond to the two guide grooves 22. The inner walls of the protective cover 213 are rotatably connected to a lead screw 28 through a bearing. The outer wall of the lead screw 28 is threaded to a connecting rod 26. The inner walls of the other protective cover 213 are welded to an auxiliary slide rod 210, and the outer wall of the auxiliary slide rod 210 is also slidably connected to a connecting rod 26.

[0028] The cleaning assembly 2 also includes a crossbar 24. Both the crossbar 24 and the vertical bar 25 are made of metal square tubing and are fixedly connected by welding. The weld joint is ground to avoid scratching the cleaning sponge. One end of each of the two vertical bars 25 is slidably connected to the inner wall of the corresponding guide groove 22. The sliding surface is coated with grease to reduce friction. One end of each vertical bar 25 is flush with the top of the top plate 21. The bottom of each of the two connecting rods 26 is fixedly connected to the top of the two vertical bars 25 at their respective positions by bolts. The bolts are locked with anti-loosening nuts. The crossbar 24 is slidably connected to the inner bottom of the water tank 1, and one side of each vertical bar 25 is slidably connected to the inner wall of one side of the water tank 1. Cleaning sponges are attached to the sliding contact points. The cleaning sponges are connected to the crossbar 24 and the vertical bar 25 by Velcro for easy replacement later.

[0029] A sealing plate 27 is fixedly connected to one side of each of the two connecting rods 26 by bolts. The sealing plate 27 is made of elastic material and has a smooth surface to reduce friction with the protective cover 213. The sealing plate 27 covers the top of the guide groove 22. The sealing plate 27 is slidably connected to the inner wall of the protective cover 213. A guide groove is opened at the part of the inner wall of the protective cover 213 that contacts the sealing plate 27 to prevent the sealing plate 27 from shifting.

[0030] A through hole 214 is provided on one side of the protective cover 213, through which the sealing plate 27 can pass smoothly. The edges of the through hole 214 are rounded to avoid scratching the sealing plate 27.

[0031] A servo motor 29 is fixedly installed on one side of the water tank 1 by bolts. The servo motor 29 has forward and reverse rotation control function. Its output shaft is fixedly connected to one end of the lead screw 28 through a coupling. The coupling is used to compensate for installation errors.

[0032] A cleaning sponge is fixedly connected to the side of the vertical bar 25 and the horizontal bar 24 that slides in contact with the inner wall of the water tank 1. The cleaning sponge has sufficient wiping pressure and water absorption capacity.

[0033] A first interface pipe 211 is fixedly connected to the inside of one side wall of the water storage tank 1 by welding. A valve 212 is fixedly installed at one end of the first interface pipe 211 by thread. The valve 212 is selected to be easy to operate, and the operating handle can be designed as an extended structure according to requirements.

[0034] The top plate 21 has a water injection hole 23 inside. The top of the top plate 21 is fixedly connected to the second interface pipe 215 by welding. The outer wall of the second interface pipe 215 is provided with external threads. The inner wall of the second interface pipe 215 is provided with an installation groove 218. The L-shaped rod 219 is made of a material with a certain degree of elasticity, which is convenient for insertion and disassembly. One end of the L-shaped rod 219 is fixedly connected to the assembly ring 220 by glue. The inner wall of the assembly ring 220 is fixedly connected to the filter screen 221 by glue. One end of the second interface pipe 215 is threaded to the outer wall and has a sealing cap 216. The inner wall of the sealing cap 216 is provided with internal threads, and sealing material is wrapped around the threads to enhance the sealing performance. The outer wall of the sealing cap 216 is integrally molded with a handle 217 by injection molding. The surface of the handle 217 is provided with anti-slip texture for easy gripping.

[0035] All electrical devices in this plan are powered by an external power source.

[0036] Working principle: When water needs to be added to the water storage tank 1, the operator first holds handle 217 and unscrews the sealing cap 216 to connect the external water supply pipe to the second interface pipe 215. After opening the external water supply valve, water flows in along the second interface pipe 215. When it passes through the filter screen 221 on the inner wall of the assembly ring 220, impurities in the water are intercepted by the filter screen 221, and the filtered clean water enters the water storage tank 1 through the water inlet 23. After the water is added, the external water supply valve is closed, the water supply pipe is unscrewed, and then the sealing cap 216 is screwed back onto the second interface pipe 215 to complete the sealing. If the filter screen 221 becomes clogged or damaged, simply pull the L-shaped rod 219 out of the mounting slot 218, replace the assembly ring 220 with a new filter screen 221, and then reinsert the L-shaped rod 219 to complete the maintenance.

[0037] When dirt accumulates on the inner wall of the water tank 1 and needs cleaning, the servo motor 29 is activated, and the output shaft of the servo motor 29 drives the lead screw 28 to rotate. Since the lead screw 28 is threadedly connected to the connecting rod 26, and the connecting rod 26 on the other side is restricted from rotating by the auxiliary slide rod 210, the rotation of the lead screw 28 is converted into the linear movement of the connecting rod 26 along the axis of the lead screw 28. The two connecting rods 26 move synchronously, driving the longitudinal rod 25 to slide along the guide groove 22, and the longitudinal rod 25 further drives the transverse rod 24 to move along the bottom of the water tank 1. During the movement, the cleaning sponge on one side of the longitudinal rod 25 and the bottom of the transverse rod 24 is always in close contact with the side wall and bottom of the water tank 1, wiping and removing the scale and impurities attached to the inner wall; at the same time, the connecting rod 26 drives the sealing plate 27 to slide along the inner wall of the protective cover 213, and the sealing plate 27 always covers the top of the guide groove 22 to prevent external dust from entering the water tank 1 through the guide groove 22. When the cleaning component 2 moves to one end of the water tank 1, the servo motor 29 is reversed, driving the cleaning component 2 to move in the opposite direction to achieve reciprocating cleaning and ensure thorough cleaning.

[0038] After cleaning is complete, turn off the servo motor 29 and open the valve 212 on the first interface pipe 211. The wastewater containing dirt in the water tank 1 will be discharged along the first interface pipe 211 under gravity. After the wastewater is basically drained, the servo motor 29 can be briefly started to drive the cleaning component 2 to move back and forth again, thoroughly scraping the remaining wastewater and dirt into the first interface pipe 211 for discharge. After the drainage is complete, close the valve 212, and water can be refilled into the water tank 1 for later use. The entire process does not require manual entry into the water tank, making the operation safe and efficient.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
