[0036] The technical scheme of the utility model will be further illustrated below by specific embodiments in combination with the drawings.

[0037] The embodiment provides a water adding device, as shown in Figure 1 and Figure 2 The water adding device comprises a water storage tank 1, a water pump 2 and a water adding post 3, a water inlet is formed in the water storage tank 1, the water inlet is connected with a water inlet pipe 11, the water pump 2 is arranged in the water storage tank 1, the water pump 2 is connected with a water outlet pipe 12, the water outlet pipe 12 is arranged in the water storage tank 1, and the water adding post 3 comprises a water adding pipe 32, the water adding pipe 32 is communicated with the water outlet pipe 12.

[0038] In the water adding device, the water storage tank 1 can carry out water storage operation at any time, when the cleaning vehicle needs to be replenished, the water pump 2 can quickly replenish the water in the water storage tank 1 to the cleaning vehicle in the form of high pressure, greatly improving the water replenishing efficiency of the cleaning vehicle. And the water inlet pipe 11 can carry out water storage in the water storage tank 1 when the cleaning vehicle is in a working state or an idle state and does not need to be replenished, so even if the water replenishing rate of the water inlet pipe 11 is low, it will not affect the cleaning vehicle.

[0039] The water adding device can improve the water replenishing efficiency of the cleaning vehicle and shorten the water replenishing time.

[0040] In order to reduce the work intensity of the operator, the water adding device further comprises a liquid level limiting structure arranged in the water storage tank 1, which is connected with the water inlet pipe 11 to open or close the water inlet pipe 11. When the liquid level in the water storage tank 1 reaches a preset height, the liquid level limiting structure closes the water inlet pipe 11, so as to avoid the overflow of the water storage tank 1 due to the excessively high liquid level. When the liquid level in the water storage tank 1 is lowered due to the water supplement to the cleaning vehicle, the liquid level limiting structure opens the water inlet pipe 11, so as to avoid the insufficient water level after multiple water supplement to the cleaning vehicle, which affects the subsequent water supplement efficiency.

[0041] That is, the liquid level limiting structure can automatically open or close the water inlet pipe 11 according to the state of the liquid level, so as to ensure that the liquid level is in a proper range.

[0042] In some embodiments, the liquid level limiting structure can be a liquid level sensor and a solenoid valve. When the liquid level is lower than the liquid level sensor, the solenoid valve is opened, and the water inlet pipe 11 supplements water into the water storage tank 1. When the liquid level reaches the liquid level sensor, the solenoid valve is closed.

[0043] As shown in Figure 1 In the present embodiment, the liquid level limiting structure is a float ball valve 15, which comprises a valve body, a connecting rod and a float ball. The valve body is arranged in the water inlet pipe 11, the connecting rod connects the valve body and the float ball. When the liquid level in the water storage tank 1 contacts the float ball, the float ball rises to drive the connecting rod to rotate, and the valve body gradually closes, so that the water inlet pipe 11 is closed and the water supplement is stopped. When the liquid level in the water storage tank 1 is lowered, the float ball is lowered to drive the connecting rod to rotate, and the valve body gradually opens, so that the water inlet pipe 11 can supplement water into the water storage tank 1.

[0044] It is worth noting that the float ball valve 15 is used to control the liquid level in the water storage tank 1, which has a simple structure, low cost and high reliability of the pure mechanical structure.

[0045] In the present embodiment, the water storage tank 1 comprises 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 arranged on the bottom surface of the tank body 13. The water pump 2 can pump most of the water in the tank body 13 for water supplement to the cleaning vehicle, thereby reducing water waste. Meanwhile, the detachable top cover 14 facilitates the cleaning of the water storage tank 1.

[0046] As shown in Figure 1 The top cover 14 is provided with a water outlet, and the water outlet pipe 12 is arranged in the water outlet and fixedly connected with the top cover 14. This structure facilitates the removal of the water outlet pipe 12 or the water pump 2 when the top cover 14 is removed. Moreover, no sealing ring or other sealing structure is needed between the water outlet pipe 12 and the top cover 14. Compared with the structure in which the water outlet pipe 12 is arranged at the lower part of the tank body 13, the complexity of the structure is greatly reduced, and the cost is reduced.

[0047] 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 the water pump 2 will not cause the water pumping resistance to increase or the water storage tank 13 to deform when the water pump 2 is working to lower the liquid level in the water storage tank 13.

[0048] In the embodiment, the bottom of the water storage tank 13 is provided with a drain valve 16 for draining the water in the water storage tank 13.

[0049] As shown in Figure 1 the water outlet pipe 12 includes a plurality of straight pipes 121, and adjacent two straight pipes 121 are connected through an elbow pipe 122. Generally, the water inlet of the water filling pipe 32 is located below the sleeve 312, and the water outlet pipe 12 can change the extension direction of the water outlet pipe 12 through the elbow pipe 122, so that the water outlet pipe 12 can be connected with the water filling pipe 32.

[0050] Further, the straight pipe 121 and the elbow pipe 122 are detachable, and the position of the water inlet of the water filling pipe 32 can be determined according to the height of the water filling pipe 32, so that the straight pipe 121 with appropriate length can be replaced to enable the water outlet pipe 12 to be connected with the water filling pipe 32.

[0051] Specifically, the straight pipe 121 and the elbow pipe 122 can be in interference fit. In the embodiment, the straight pipe 121 and the elbow pipe 122 are threadedly connected, and such connection structure can ensure the reliability and sealing of the connection to avoid water leakage.

[0052] In the embodiment, the water inlet of the water storage tank 1 is sealingly connected with the water inlet pipe 11, and the water outlet of the water storage tank 1 is sealingly connected with the water outlet pipe 12, which can not only avoid water leakage, but also prevent dust and other impurities from entering the water storage tank 1. The sealing connection is achieved by setting a sealing ring or welding.

[0053] Generally, in order to facilitate cleaning, the water storage tank 1 needs to be lifted to a certain height, which can also avoid the water storage tank 1 from being contaminated by the garbage on the ground or being corroded by the accumulated water. To achieve the above purpose, the water filling device further includes a support seat 4 arranged below the water storage tank 1 to support the water storage tank 1.

[0054] It can be understood that the water filling device is arranged outdoors, and when the temperature is low, the water inlet pipe 11, the water outlet pipe 12 and the water filling pipe 32 are prone to burst due to water icing. To solve the above problem, the water inlet pipe 11, the water outlet pipe 12 and the water filling pipe 32 are each sleeved with a heat preservation layer.

[0055] It can be understood that the heights of the cleaning vehicles that need to be filled with water are different. As shown in Figures 1 to 3As shown, in order to adapt to the cleaning vehicles with different heights, the water filling post 3 further comprises a support 31, and the water filling pipe 32 is arranged in the support 31 in a liftable manner, so that the operator can adjust the height of the water filling post 3 to perform the water filling operation on the cleaning vehicles with different heights.

[0056] As shown in Figures 1 to 4 The support 31 comprises a plurality of support arms 311 and a sleeve 312, the plurality of support arms 311 are arranged around the outer periphery of the sleeve 312 and are fixedly connected with the sleeve 312, and the water filling pipe 32 is arranged through the sleeve 312 and is slidably connected with the sleeve 312. The sleeve 312 is used for guiding the water filling pipe 32, so that the water filling pipe 32 can be kept stable during the lifting process, and the water filling pipe 32 can also be prevented from tilting. The plurality of support arms 311 can improve the strength and stability of the support 31.

[0057] In the embodiment, the water filling post 3 comprises a base 36, the support 31 comprises three support arms 311, the three support arms 311 are arranged at equal intervals between each other, and the three support arms 311 are fixedly arranged on the base 36. The base 36 is fixed to the ground by expansion screws, so as to improve the stability of the support 31.

[0058] It is worth noting that, since the water filling pipe 32 is arranged through the sleeve 312, the bottom of the water filling pipe 32 is connected with the water outlet pipe 12. In order to prevent the sleeve 312 from blocking the connection between the water filling pipe 32 and the water outlet pipe 12, the sleeve 312 is arranged at an interval with the base 36, and the interval is the stroke of the height adjustment of the water filling pipe 32.

[0059] Generally speaking, the strength of the support arm 311 determines the stability of the support 31. As shown in Figure 3 and Figure 5 In the embodiment, the support arm 311 comprises two support plates 3111 arranged at an interval and a connecting plate 3112 connected with the two support plates 3111, and the support plate 3111 is fixedly connected with the sleeve 312.

[0060] That is to say, the support arm 311 has a C-shaped cross-sectional structure. The support arm 311 with such a structure has two connection lines with the sleeve 312, which ensures the reliability of the connection between the support arm 311 and the sleeve 312, and the sleeve 312 cannot rotate or move relative to the support arm 311. On the other hand, the support arm 311 with such a structure is close to a hollow structure, and the bending structure can not only meet the requirement of less material and lower cost, but also can make the strength and rigidity of the support arm 311 higher, thereby improving the stability of the support 31.

[0061] In the embodiment, the support 31 is made of a metal material, which has lower cost and better mechanical properties. Preferably, the support 31 is made of steel, iron or the like.

[0062] 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.

[0063] 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.

[0064] The slide rail 33 is welded and fixed to the water supply pipe 32, which is a simple process with low cost.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The fixing plate 332 and the sleeve 312 can be fixed by the connection of the fastening screw 34 and the fastening nut 35. Before the slide rail 33 and the water feeding pipe 32 are welded, the fastening nut 35 needs to be fixed on the side of the fixing plate 332 facing the water feeding pipe 32.

[0069] In order to fix the water feeding pipe 32 at different height positions, the sleeve 312 is provided with a plurality of fixing holes 3121 spaced apart in the vertical direction. After the height of the water feeding pipe 32 is adjusted in place, the operator can select the appropriate fixing hole 3121 for fixing according to the position of the fastening nut 35.

[0070] Further, the fixing plate 332 is provided with a plurality of fastening nuts 35 fixed in the vertical direction. The water feeding pipe 32 and the sleeve 312 are fixed by the plurality of fastening nuts 35 and the corresponding fastening screws 34, which can further improve the stability of the water feeding pipe 32, while also reducing the load borne by each fastening screw 34, thereby improving the service life.

[0071] It is worth noting that the number and spacing distance of the fixing holes 3121 represent the number of fixing positions of the water feeding pipe 32 of the water feeding pipe 3, and the water feeding pipe 32 does not need too many 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 the two adjacent fastening nuts 35 is an integer multiple of the distance between the two adjacent fixing holes 3121.

[0072] This structure can ensure that when one fastening nut 35 of the water feeding pipe 32 corresponds to the fixing hole 3121, all the fastening nuts 35 can correspond to the fixing hole 3121 of the sleeve 312, ensuring that each fastening nut 35 can correspond to the fastening screw 34.

[0073] In some embodiments, the fastening member can also be a clamping column elastically extended to the slide rail 33, which can selectively pass through a fixing hole 3121 to fix the relative position between the water feeding pipe 32 and the sleeve 312. When the height of the water feeding pipe 32 needs to be adjusted, the operator only needs to press the clamping column to make it retract and disengage from the fixing hole 3121.

[0074] As shown in Figure 3 As shown in

[0075] As shown inFigure 1 and Figure 2 As shown in the figure, the water adding device further comprises an electric valve 38 arranged on the water adding pipe 32, and the electric valve 38 can open or close the water adding pipe 32. The arrangement of the electric valve 38 enables the water adding device 3 to realize the function of automatic water adding, and the water adding can be started after the cleaning vehicle is parked in place, thereby improving the efficiency.

[0076] The above is only the preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as the limitation of the present application.
