[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] This embodiment provides a water adding device, such as... Figure 1 and Figure 2 As shown, the water filling device includes a water storage tank 1, a water pump 2, and a water filling pile 3. The water storage tank 1 has a water inlet for connecting to a water inlet pipe 11. The water pump 2 is installed inside the water storage tank 1 and is connected to a water outlet pipe 12, which passes through the water storage tank 1. The water filling pile 3 includes a water filling pipe 32, which is connected to the water outlet pipe 12.

[0039] In this water filling device, the water tank 1 can store water at any time. When the cleaning vehicle needs water, the water pump 2 can quickly replenish the water in the water tank 1 to the cleaning vehicle in a high-pressure manner, greatly improving the water replenishment efficiency of the cleaning vehicle. The water inlet pipe 11 can store water in the water tank 1 when the cleaning vehicle is in working or idle state and does not need water replenishment. Therefore, even if the water replenishment rate of the water inlet pipe 11 is low, it will not affect the cleaning vehicle.

[0040] This water-addition device can improve the water replenishment efficiency of the cleaning vehicle and shorten the water replenishment time.

[0041] To reduce the workload of operators, the water supply device also includes a liquid level limiting structure, which is installed inside the water tank 1 and connected to the water inlet pipe 11 to open or close the pipe. When the liquid level in the water tank 1 reaches a preset height, the liquid level limiting structure closes the water inlet pipe 11 to prevent the liquid level in the water tank 1 from becoming too high and overflowing. When the liquid level in the water tank 1 decreases as water is added to the cleaning vehicle, the liquid level limiting structure opens the water inlet pipe 11 to prevent insufficient water level after repeated additions to the cleaning vehicle, which would affect the efficiency of subsequent water additions.

[0042] In other words, the liquid level limiting structure can automatically open or close the inlet pipe 11 according to the state of the liquid level, thereby ensuring that the liquid level is within a suitable range.

[0043] In some embodiments, the liquid level limiting structure can be a liquid level sensor and a solenoid valve. The liquid level sensor is installed in the water storage tank 1. When the liquid level is lower than the liquid level sensor, the solenoid valve opens and the water inlet pipe 11 replenishes water into the water storage tank 1. When the liquid level reaches the liquid level sensor, the solenoid valve closes.

[0044] like Figure 1 As shown, in this embodiment, the liquid level limiting structure is a float valve 15. The float valve 15 includes a valve body, a connecting rod, and a float. The valve body is located on the inlet pipe 11, and the connecting rod connects the valve body and the float. When the liquid level in the water tank 1 contacts the float, the float rises, causing the connecting rod to rotate, and the valve body gradually closes, thereby closing the inlet pipe 11 and stopping water replenishment. When the liquid level in the water tank 1 drops, the float descends, causing the connecting rod to rotate, and the valve body gradually opens, allowing water to be replenished into the water tank 1 through the inlet pipe 11.

[0045] It is worth noting that using the float valve 15 to control the liquid level in the water storage tank 1 has a simple structure, low cost, and high reliability due to its purely mechanical structure.

[0046] In this embodiment, the water tank 1 includes a tank body 13 and a top cover 14. The top cover 14 is detachably connected to the top of the tank body 13, and the water pump 2 is disposed on the bottom surface of the tank body 13. The water pump 2 can pump out most of the water in the tank body 13 for adding water to the cleaning vehicle, reducing water waste. At the same time, the detachable top cover 14 facilitates cleaning of the water tank 1.

[0047] like Figure 1 As shown, the top cover 14 has a water outlet, and the water outlet pipe 12 passes through the water outlet and is fixedly connected to the top cover 14. This structure makes it easy to remove the water outlet pipe 12 or the water pump 2 when disassembling the top cover 14. Moreover, there is no need to install a sealing ring or other sealing structure between the water outlet pipe 12 and the top cover 14. Compared with the structure in which the water outlet pipe 12 is located at the bottom of the box body 13, the structure complexity is greatly reduced and the cost is reduced.

[0048] In order to balance the air pressure inside and outside the water storage tank 1, the top cover 14 is provided with a through hole 141 to ensure that when the water pump 2 is working to lower the liquid level in the tank 13, the pump resistance will not increase or the tank 13 will deform due to the low pressure inside the tank 13.

[0049] In this embodiment, a drain valve 16 is provided at the bottom of the box 13 to drain the water inside the box 13.

[0050] like Figure 1 As shown, the water outlet pipe 12 includes multiple straight pipe sections 121, and adjacent straight pipe sections 121 are connected by elbow pipes 122. Generally, the water inlet of the water inlet pipe 32 is located below the sleeve 312, and the water outlet pipe 12 can change its extension direction through the elbow pipes 122, thereby enabling the water outlet pipe 12 to be connected to the water inlet pipe 32.

[0051] Furthermore, the straight pipe 121 and the elbow pipe 122 are detachable, and the position of the water inlet of the water inlet pipe 32 can be determined according to the height of the water inlet pipe 32, so that the straight pipe 121 of appropriate length can be replaced so that the water outlet pipe 12 can be connected to the water inlet pipe 32.

[0052] Specifically, the straight pipe 121 and the elbow pipe 122 can be interference-fitted. In this embodiment, the straight pipe 121 and the elbow pipe 122 are threaded together. This connection structure can ensure the reliability and sealing of the connection and prevent water leakage.

[0053] In this embodiment, the inlet of the water storage tank 1 is sealed to the inlet pipe 11, and the outlet of the water storage tank 1 is sealed to the outlet pipe 12. This not only prevents water leakage but also prevents dust and other impurities from entering the water storage tank 1. The sealing connection is achieved by setting a sealing ring or welding.

[0054] Generally, to facilitate cleaning, the water tank 1 needs to be raised to a certain height, which also prevents the water tank 1 from being contaminated by garbage on the ground or corroded by accumulated water. To achieve the above purpose, the water filling device also includes a support base 4, which is set below the water tank 1 to support the water tank 1.

[0055] It is understandable that the water filling device is located outdoors, and when the temperature is low, the water is prone to freezing, which could cause the inlet pipe 11, outlet pipe 12, and water filling pipe 32 to burst. To solve the above problem, the inlet pipe 11, outlet pipe 12, and water filling pipe 32 are all covered with an insulation layer.

[0056] Understandably, the heights of the cleaning trucks that require water vary. For example... Figures 1-3As shown, in order to accommodate cleaning vehicles of different heights, the water filling pile 3 also includes a bracket 31, and the water filling pipe 32 can be raised and lowered on the bracket 31, so that the operator can adjust the height of the water filling pile 3 to add water to cleaning vehicles of different heights.

[0057] like Figures 1-4 As shown, the support frame 31 includes multiple support arms 311 and a sleeve 312. The multiple support arms 311 surround the outer periphery of the sleeve 312 and are fixedly connected to the sleeve 312. The water supply pipe 32 passes through the sleeve 312 and is slidably connected to the sleeve 312. The sleeve 312 is used to guide the water supply pipe 32, keeping the water supply pipe 32 stable during lifting and lowering, and also preventing the water supply pipe 32 from tilting. The multiple support arms 311 can improve the strength and stability of the support frame 31.

[0058] In this embodiment, the water filling pile 3 includes a base 36, and the bracket 31 includes three support arms 311. The three support arms 311 are arranged at equal intervals between each other, and all three support arms 311 are fixedly mounted on the base 36. The base 36 is fixed to the ground by expansion screws, thereby improving the stability of the bracket 31.

[0059] It is worth noting that since the water inlet pipe 32 passes through the sleeve 312, the bottom of the water inlet pipe 32 is connected to the water outlet pipe 12. In order to prevent the sleeve 312 from blocking the connection between the water inlet pipe 32 and the water outlet pipe 12, the sleeve 312 and the base 36 are spaced apart, and the distance of this spaced distance is the stroke for adjusting the height of the water inlet pipe 32.

[0060] Generally speaking, the strength of the support arm 311 determines the stability of the bracket 31. For example... Figure 3 and Figure 5 As shown, in this embodiment, the support arm 311 includes two support plates 3111 spaced apart and a connecting plate 3112 connected to the two support plates 3111. The support plates 3111 are fixedly connected to the sleeve 312.

[0061] In other words, the support arm 311 has a C-shaped cross-section structure. There are two connecting lines between the support arm 311 and the sleeve 312, which ensures the reliability of the connection between the support arm 311 and the sleeve 312. There will be no relative rotation or relative movement between the sleeve 312 and the support arm 311. On the other hand, the support arm 311 of this structure is close to a hollow structure, and the bent structure can not only meet the requirements of using less material and reducing costs, but also make the support arm 311 have high strength and rigidity, thus improving the stability of the bracket 31.

[0062] In this embodiment, the bracket 31 is made of metal, which is cost-effective and has good mechanical properties. Preferably, the bracket 31 is made of steel, iron, or other materials.

[0063] In this embodiment, the sleeve 312 has an anti-rotation structure, which is configured to prevent relative rotation between the water inlet pipe 32 and the sleeve 312. Since both the sleeve 312 and the water inlet pipe 32 are cylindrical structures, and the anti-rotation structure of the sleeve 312 can prevent the water inlet pipe 32 from rotating, it ensures that the outlet of the water inlet pipe 32 will not move in the horizontal direction, thereby keeping the parking position of the cleaning vehicle fixed when adding water, which is convenient for operators to operate without having to adjust the position of the cleaning vehicle multiple times.

[0064] like Figure 3 , Figure 4 and Figure 6 As shown, the inner wall of the sleeve 312 is provided with a groove 313 extending axially along the sleeve 312, and the outer wall of the water supply pipe 32 is provided with a slide rail 33. The groove 313 forms an anti-rotation structure, and the slide rail 33 is slidably disposed within the groove 313. When the water supply pipe 32 moves vertically to adjust its height, the slide rail 33 can slide within the groove 313. At this time, the two side walls of the groove 313 can guide the slide rail 33, preventing the water supply pipe 32 from rotating.

[0065] The slide rail 33 is welded and fixed to the water supply pipe 32, which is a simple process with low cost.

[0066] Understandably, once the height of the water inlet pipe 32 is adjusted to the correct position, it needs to be secured. For example... Figure 3 , Figure 4 and Figure 6 As shown, in order to achieve the above purpose, the water filling pile 3 also includes fasteners. The slide rail 33 includes two guide plates 331 spaced apart and a fixing plate 332 connected to the two guide plates 331. The two guide plates 331 slide against the corresponding side wall of the slide groove 313. The fasteners pass through the sleeve 312 and are connected to the fixing plate 332 to fix the relative position between the water filling pipe 32 and the sleeve 312.

[0067] Two guide plates 331 are welded and fixed to the water supply pipe 32. The two guide plates 331 are used to slide against the inner wall of the chute 313 to achieve a guiding effect. The two guide plates 331 can make the fixing plate 332 and the water supply pipe 32 spaced apart to provide clearance space for the fasteners and prevent the fasteners from hitting the water supply pipe 32 and causing the water supply pipe 32 to break.

[0068] Specifically, the fastener is a fastening screw 34, and a fastening nut 35 is fixedly installed on the side of the fixing plate 332 facing the water pipe 32. The sleeve 312 has a fixing hole 3121, and the fastening screw 34 passes through the sleeve 312 and the fixing plate 332 and is threadedly connected to the fastening nut 35.

[0069] The fixing plate 332 and the sleeve 312 can be fixed by connecting the fastening screw 34 and the fastening nut 35. Moreover, before welding the slide rail 33 to the water inlet pipe 32, the fastening nut 35 needs to be fixed on the side of the fixing plate 332 facing the water inlet pipe 32.

[0070] To allow the water inlet pipe 32 to be fixed at multiple different heights, the sleeve 312 is provided with multiple fixing holes 3121 spaced apart in the vertical direction. After the height of the water inlet pipe 32 is adjusted to the correct position, the operator can select the appropriate fixing hole 3121 for fixing based on the position of the fastening nut 35.

[0071] Furthermore, the fixing plate 332 is fixedly provided with a plurality of fastening nuts 35 in the vertical direction. By fixing the water inlet pipe 32 and the sleeve 312 with a plurality of fastening nuts 35 and corresponding fastening screws 34, the stability of the water inlet pipe 32 can be further improved, while the load borne by each fastening screw 34 can be reduced, thereby increasing the service life.

[0072] It is worth noting that the number and spacing of the fixing holes 3121 represent the number of fixing positions of the water supply pipe 32 of the water supply pile 3, while the water supply pipe 32 does not require a large number of fastening screws 34 and fastening nuts 35 for fixing. In order to save the number of fastening screws 34 and fastening nuts 35, the distance between two adjacent fastening nuts 35 is an integer multiple of the distance between two adjacent fixing holes 3121.

[0073] This structure ensures that when one fastening nut 35 of the water supply pipe 32 corresponds to the fixing hole 3121, all fastening nuts 35 can have corresponding fixing holes 3121 in the sleeve 312, ensuring that each fastening nut 35 can be equipped with a fastening screw 34.

[0074] In some embodiments, the fastener may also be a snap-fit ​​post that elastically extends and retracts from the slide rail 33. When extended, the snap-fit ​​post can selectively pass through a fixing hole 3121 to fix the relative position between the water inlet pipe 32 and the sleeve 312. When it is necessary to adjust the height of the water inlet pipe 32, the operator only needs to press the snap-fit ​​post to retract it and disengage it from the fixing hole 3121.

[0075] like Figure 3 As shown, along the circumference of the sleeve 312, each adjacent support arm 311 is connected and fixed by a reinforcing rod 37. Due to the high height of the support arms 311, although the bottoms of multiple support arms 311 are fixed by the base 36, the stability of the top of the support arms 311 cannot be guaranteed. The reinforcing rod 37 can connect multiple support arms 311 into a whole, thereby improving the overall strength of the bracket 31.

[0076] like Figure 1 and Figure 2 As shown, the water filling device also includes an electric valve 38, which is installed on the water filling pipe 32. The electric valve 38 can open or close the water filling pipe 32. The electric valve 38 enables the water filling pile 3 to achieve automatic water filling function, and water filling can begin as soon as the cleaning vehicle is parked in place, thus improving efficiency.

[0077] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
