[0018] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein may be combined with each other.
[0019] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "back" and other terms indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] Furthermore, in the description of the present invention, unless otherwise expressly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, these terms may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will appreciate the specific meanings of these terms in the present invention based on the specific circumstances.
[0021] The following will refer to the attached Figures 1 to 5 The present invention is described in detail with reference to the embodiments.
[0022] In general, the present invention relates to a self-cleaning metering water meter, comprising a fixed frame 1, an extension rod 4 symmetrically fixedly arranged on both sides of the top of the fixed frame 1, a horizontal rod 401 fixedly arranged between the extension rods 4, a telescopic pole 402 fixedly arranged on the horizontal rod 401, and a cleaning component fixedly arranged at the end of the telescopic pole 402. The water meter body is located in the fixed frame 1, the cleaning component is on the front side of the water meter and contacts the water meter body, and the fixed frame 1 is fixed to the wall through the fixing component; wherein, the cleaning component comprises an installation frame 201 fixedly connected to the end of the telescopic pole 402, an extension rod 2 symmetrically fixedly arranged on the side of the installation frame 201 corresponding to the water meter, a connecting shaft 301 with both ends rotatably connected to the extension rods 2 on both sides, a rotating column 3 fixedly arranged on the connecting shaft 301, and a brush 302 evenly fixedly arranged on the side of the rotating column 3; the installation frame 201 is provided with a slot 2011, and a water spray component facing the rotating column 3 is provided in the slot 2011.
[0023] In this embodiment, the cleaning assembly can periodically or automatically clean the water meter surface. The brush 302 can reach into the cracks and corners of the water meter surface to remove stubborn dirt, and the water spray assembly can rinse away the dirt, ensuring that the water meter surface remains clean at all times and the reading window is clearly visible, thereby improving the accuracy of the water meter reading.
[0024] The output shaft of motor 303 is fixedly connected to connecting shaft 301, enabling high-speed and stable rotation of rotating column 3, driving brush 302 to more effectively scrub the water meter surface. Dust, water stains, and long-accumulated dirt are effectively removed, ensuring a consistently clear reading window. This significantly improves the accuracy of water meter readings and provides a reliable basis for the rational allocation of water resources and billing.
[0025] During specific implementation, when the preset cleaning time is reached or the user manually triggers the cleaning instruction, the control system of the self-cleaning metering water meter sends a signal to start the entire cleaning program. The control system controls the telescopic pole 402 to start extending, and the telescopic pole 402 drives the cleaning component to move toward the water meter. When the cleaning component reaches the predetermined position, the control system sends an operation instruction to the motor 303. The motor 303 starts, and its output shaft drives the connecting shaft 301 to rotate at high speed, and the connecting shaft 301 further drives the rotating column 3 and the brush 302 to rotate. The brush 302 brushes the surface of the water surface at a set frequency and force, brushing off dust, dirt, etc. from the surface of the water surface. While the motor 303 drives the brush 302 to clean, the control system controls the water spray component to start working. The water spray component is connected to the water source through a pipe, and sprays water at a certain pressure and angle, directly facing the area cleaned by the rotating column 3 and the brush 302. The sprayed water washes away the dirt brushed off by the brush 302, so that the dirt leaves the water surface with the water flow, After completing the preset cleaning time and number of flushes, the control system stops motor 303 and the water spray assembly. The control system then retracts telescopic pole 402, moving the cleaning assembly away from the water meter and returning it to its initial position. At this point, the water meter surface is clean, the reading window is clearly visible, and the meter returns to normal operation, ready for the next metering cycle and possible cleaning.
[0026] Specifically, the self-cleaning water meter can be cleaned automatically, eliminating the need for regular manual cleaning. Users can set the cleaning time and frequency based on their needs, and the meter will automatically start the cleaning process at the set time, improving user convenience and saving labor and time costs.
[0027] Among them, Figure 3 and Figure 5 As shown, the water spray assembly includes a water tank 2012 fixedly arranged in the groove 2011, and a plurality of nozzles 2013 are spaced apart on the side of the water tank 2012 corresponding to the rotating column 3. The water tank 2012 is connected to the connecting pipe 2014, and the connecting pipe 2014 passes through the outside of the installation frame 201 and is connected to external equipment.
[0028] The multiple, spaced-apart nozzles 2013 within the water spray assembly spray water from all angles across the water meter surface. Combined with the brush 302, this more thoroughly removes all types of surface dirt, including fine dust particles, stubborn water stains, and adhering impurities. This ensures the meter's reading window remains highly clear, enabling meter readers to accurately read water consumption data, avoiding reading errors caused by dirt obstruction and improving meter accuracy.
[0029] It should be noted that the water pressure and flow rate of water tank 2012 can be adjusted via external devices, allowing users to flexibly adjust cleaning parameters based on the meter's operating environment and the level of dirt. For example, in dusty environments, the water pressure and flow rate can be increased to enhance cleaning effectiveness; in relatively clean environments with low water consumption, the water pressure and flow rate can be reduced to conserve water resources. This flexible adjustment allows the self-cleaning meter to adapt to different usage scenarios, enhancing the product's versatility and practicality.
[0030] Based on the above settings, the water meter is fixed to the wall through the fixing components, which can provide stable support and protection for the water meter, and also facilitate the installation and debugging of the cleaning components. Figure 4 As shown, the fixing assembly includes a fixing rod 101 and a fixing plate 102. A plurality of fixing rods 101 are fixedly and symmetrically provided on the side of the fixing frame 1 opposite to the wall. The fixing plate 102 is fixedly arranged at the end of the fixing rod 101 and fixedly connected to the wall through a fixing bolt 103.
[0031] In this embodiment, multiple fixing rods 101 are symmetrically fixed to the side of the fixing frame 1 opposite the wall surface, which can evenly distribute the weight of the water meter and the forces generated during operation across the multiple fixing rods 101. Compared with a single fixing rod 101 or a small number of fixing rods 101, the stress on each fixing rod 101 is reduced, and the risk of deformation or breakage of the fixing rod 101 due to excessive force is reduced. This enhances the installation stability of the entire device on the wall, ensures the long-term stable operation of the water meter, and reduces measurement errors and equipment damage caused by unstable installation.
[0032] As a preferred structure of the present invention, Figure 3 As shown, upper plates 5 for shielding water stains are fixedly and symmetrically provided on the upper and lower sides of the installation frame 201. The upper plate 5 on the upper side extends obliquely upward along the direction of the water meter body, and the upper plate 5 on the lower side extends obliquely downward along the direction of the water meter body.
[0033] The upper plates 5 symmetrically arranged on the upper and lower sides of the installation frame 201 form a three-dimensional protective space, which can prevent water stains from the water spray assembly from splashing upward or downward, avoid water stains from splashing to other parts of the water meter body, reduce the potential damage of water stains to the internal mechanical structure and electronic components of the water meter, and reduce the probability of water meter failure.
[0034] In this embodiment, a front plate 403 is fixed to the end of the extension rod 4, with the axis of the front plate 403 located in front of the cleaning assembly. When the cleaning assembly is finished, the telescopic pole 402 drives it upward and resets it, and the front plate 403 is located just in front of the cleaning assembly, protecting the cleaning assembly and reducing exposure.
[0035] Based on the above configuration, side panels 6 are fixedly provided on both sides of the installation frame 201 , and the side panels 6 are connected to the side walls of the fixing frame 1 in an upward and downward sliding manner.
[0036] During specific implementation, the side panels 6 follow the mounting frame 201 and slide up and down along the height direction of the fixed frame 1. After the cleaning component is reset, the side panels 6 on both sides can form protection with the front panel 403, further forming protection to reduce exposure. At the same time, it also provides guidance for the up and down movement of the cleaning component on the fixed frame 1, further increasing the stability during cleaning.
[0037] In addition, as preferably, the bottom of the fixing frame 1 is fixedly provided with a bottom groove 8, and the bottom groove 8 is just below the cleaning component. During the cleaning process, the cleaning component will clean up the sewage, dust, debris and other debris on the surface of the object, and these sewage and debris will fall directly into the bottom groove 8.
[0038] It should be noted that after the cleaning component wipes or scrubs the water meter body, moisture will remain on the water meter surface and the brush 302. If not dried in time, the moisture may remain and breed scale and bacteria, affecting the reading accuracy and service life of the water meter. At the same time, the wet brush 302 is also easily damaged or breeds odor. In this embodiment, if Figure 2 and Figure 4 As shown, a fan 9 is fixed between the extension rods 4, and an air outlet 901 is provided at the bottom of the fan 9. The air outlet 901 is directly opposite the position between the cleaning component and the water meter body, and can dry the cleaned brush 302 and the water meter surface.
[0039] In order to increase the stability between the fixed frame 1 and the water meter, as Figure 4 As shown, in this embodiment, a connecting component is further provided on the inner side of the fixed frame 1, and the connecting component includes telescopic columns 7 symmetrically arranged on the inner side wall of the fixed frame 1. The telescopic columns 7 are slidably connected to the fixed frame 1, and the water meter body is located between the telescopic columns 7 on both sides. An abutment piece 702 is fixedly provided at one end of the telescopic column 7 close to the water meter body, and the abutment piece 702 abuts against the water meter body; a spring 701 is mounted on the telescopic column 7, one end of the spring 701 is fixedly connected to the telescopic column 7, and the other end is fixedly connected to the fixed frame 1.
[0040] By combining the telescopic column 7 with the spring 701 , a uniform clamping force can be applied to the water meter body from both sides, ensuring that the water meter does not shake or shift in the fixing frame 1 , thereby ensuring the stability and measurement accuracy of the water meter during use.
[0041] In addition, water meter bodies of different specifications may have different sizes, and the telescopic column 7 is slidably connected on the fixed frame 1, so that the connection component has a certain adaptability.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
