Detailed Implementation

[0021] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figure 1 This utility model provides a water meter cleaning device 10, including a rod assembly 20, a blower assembly 30, a spraying assembly 40, and a control assembly 50. The blower assembly 30 is installed at one end of the rod assembly 20, the water storage end of the spraying assembly 40 is installed on the rod assembly 20, and the water spraying end is installed at the end of the rod assembly 20 where the blower assembly 30 is installed, so that the blower assembly 30 and the water spraying end of the spraying assembly 40 are sent into the water meter well through the rod assembly 20. The blower assembly includes a blower 31, the spraying assembly 40 is used to remove dirt on the meter dial, and the blower assembly 30 is used to remove residue left on the meter dial by the spraying assembly 40. The water droplets are controlled by a control component 50 mounted on a pole assembly 20 and electrically connected to a blower assembly 30. This control component 50 controls the opening and closing of the blower assembly 30. Thus, when the water meter dial in the water meter well needs to be cleaned, the water spraying ends of the blower assembly 30 and the spraying assembly 40 are first sent into the water meter well through the pole assembly 20. Then, the water spraying end of the spraying assembly 40 is aimed at the dial to wash away the dirt on the dial. Finally, the blower assembly 30 is activated by the control component 50 to remove the remaining dirt and water droplets on the dial by blowing air, making the data on the dial clearly visible and thus improving meter reading efficiency.

[0023] Please refer to Figures 1 to 3 Furthermore, the rod assembly 20 includes a first support rod 21 and a second support rod 22. One end of the first support rod 21 is used to install the blower assembly 30, and the other end is used to thread a connection with one end of the second support rod 22, so as to form a complete support rod with the second support rod 22. In this way, when moving the water meter cleaning device 10, the support rod can be disassembled into the first support rod 21 and the second support rod 22 for easy handling by the operator.

[0024] In this embodiment, the pole assembly 20 has various lengths, such as 1.5m, 2.0m and 2.5m. This is because the depth of water meter wells varies at different latitudes in China. Generally, the higher the latitude, the deeper the water meter well. Thus, by setting pole assemblies 20 of different lengths, the cleaning needs of water meter wells at different latitudes in China can be met.

[0025] Please refer to Figure 3 Furthermore, the rod assembly 20 also includes a handle 23, which is installed at the end of the second support rod 22 away from the first support rod 21. The handle 23 is provided with a number of anti-slip protrusions 24 to facilitate the operator's grip on the second support rod 22.

[0026] Please refer to Figure 3Furthermore, the rod assembly 20 also includes two identical retaining rings 25 and a shoulder strap 26. The two retaining rings 25 are respectively disposed on the handle 23 and the end where the second support rod 22 is connected to the first support rod 21. The two ends of the shoulder strap 26 are detachably mounted on the two retaining rings 25, so that the operator can carry the water meter cleaning device 10 on his back through the shoulder strap 26, and so that the shoulder strap 26 can be easily removed from the two retaining rings 25.

[0027] Please refer to Figure 2 Furthermore, the fixed end of the blower 31 is mounted on the first support rod 21, and the air outlet end of the blower 31 is at a certain angle to the first support rod 21 so as to align the air outlet end of the blower 31 with the dial.

[0028] Please refer to Figure 2 Furthermore, the blower assembly 30 also includes an illumination element 32, which is mounted on the blower 31 and the illumination direction of the illumination element 32 is the same as the direction in which the air outlet of the blower 31 faces, so as to illuminate the front of the blower 31 and make it easier for the operator to align the air outlet of the blower 31 with the dial.

[0029] Please refer to Figures 2 to 3 Furthermore, the control component 50 includes a battery box 51, a blower switch 52, and a lighting switch 53. The battery box 51 is mounted on the rod assembly 20 and is electrically connected to the blower 31 and the lighting component 32 to supply power to them. The blower switch 52 is mounted on the handle 23 for easy operation by the operator and is electrically connected to the blower 31 to control its opening and closing. The lighting switch 53 is mounted on the battery box 51 and is electrically connected to the lighting component 32 to control its on / off state.

[0030] Please refer to Figures 3 to 4Furthermore, the spray assembly 40 includes a water spray switch 41, a water reservoir 42, and a water spray pipe 43. The water spray switch 41 is mounted on the second support rod 22 and is close to the handle for easy operation. One end of the water reservoir 42 is connected to the water spray switch 41, and the other end is connected to one end of the water spray pipe 43. The air pressure in the water reservoir 42 can be adjusted by the water spray switch 41 to allow water in the water reservoir 42 to flow into the water spray pipe 43 or stop the flow. Specifically, when it is necessary for water in the water reservoir 42 to flow into the water spray pipe 43, the water spray switch 41 is turned on, so that the end of the water reservoir 42 connected to the water spray switch 41 is connected to the outside, allowing water to flow from the water reservoir 42 into the water spray pipe 43. When it is not necessary for water in the water reservoir 42 to flow into the water spray pipe 43, the water spray switch 41 is turned off, so that water in the water reservoir 42 flows into the water spray pipe 43. One end of 42 connected to the water spray switch 41 is not connected to the outside so that water does not flow into the water spray pipe 43 under atmospheric pressure. The other end of the water spray pipe 43 extends into the interior of the blower 31 and is fixedly installed at the air outlet of the blower 31. The water in the water spray pipe 43 is drawn out and sprayed onto the dial by the pressure difference generated between the blower 31 and the inside of the water spray pipe 43 during the blowing process. Specifically, when the blower 31 blows air outward, the air velocity at the air outlet of the blower 31 increases, causing the air pressure at the air outlet of the blower 31 to decrease to below the standard atmospheric pressure. The air pressure inside the water spray pipe 43 is the standard atmospheric pressure. The water in the water spray pipe 43 is drawn out and sprayed onto the dial by the pressure difference between the air outlet of the blower 31 and the inside of the water spray pipe 43, thereby rinsing the dial.

[0031] In this way, when cleaning the dial, the operator can decide on the cleaning method according to the type of dirt attached to the dial. When encountering dirt containing moisture, such as mud, it is first rinsed with water in the water spray pipe 43, and then the residual dirt and water droplets are blown away by the blower 31. When encountering dirt without moisture, such as dust, it is not necessary to rinse with water spray pipe 43, but only blown away by the blower 31.

[0032] In this embodiment, the water spray pipe 43 extends into the blower 31 from inside the rod assembly 20 to prevent the water spray pipe 43 from colliding with the rod assembly 20 during movement, which could cause the water spray pipe 43 to break.
