Description

A remote controlled water meter

Technical Field

The utility model mainly relates to the technical field of water meters, in particular to a remote-controlled water meter.

Background Art

A water meter is an instrument for measuring water flow. Most water meters measure the cumulative flow of water and are generally divided into two categories: volumetric water meters and velocity water meters. Currently, there are two types of water meters: mechanical water meters and smart water meters. The process of reading gear data for mechanical water meters is complicated, while the photoelectric conversion data reading of smart water meters has a short life span and is prone to aging, resulting in short circuit failure, difficulty in control, and inaccurate data reading. The internal structure of a traditional water meter can be divided into three major parts from the outside to the inside: a shell, a sleeve, and an inner core. When selecting the specifications of a water meter, you should first estimate the size and range of the flow rate normally used, and then select the water meter with the specification that is closest to the commonly used flow rate as the first choice.

Smart water meter is a new type of water meter that uses modern microelectronics technology, modern sensor technology, and smart IC card technology to measure water consumption and transmit water consumption data and settle transactions. Smart water meter can record and electronically display water consumption, and can also control water consumption according to the agreement, automatically complete the water fee calculation of tiered water prices and water data storage. When the water meter detects that the user's bill is in arrears, it will automatically close the valve. However, the existing water meters only have one valve core to control the water flow. Over time, the valve core will wear and cause water leakage, which will affect the accuracy of the flow sensor detection and cause inaccurate user bills.

DETAILED DESCRIPTION

In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and/or" used herein includes any and all combinations of one or more related listed items.

Please refer to Figures 1-4 in particular. A remote-controlled water meter includes a water meter body 1, wherein the water meter body 1 includes a lower shell 11 and an upper shell 12, wherein a water inlet 111 and a water inlet joint 112 are provided on one side of the lower shell 11, and the water inlet 111 and the water inlet joint 112 are connected by threads, wherein a water outlet 121 and a water outlet joint 122 are provided on one side of the upper shell 12, and the water outlet 121 and the water outlet joint 122 are connected by threads, wherein a base 13 is provided in an inner cavity formed by the lower shell 11 and the upper shell 12, wherein a valve stem 14 is rotatably connected to the base 13, wherein a connecting sleeve 15 is provided on the valve stem 14, wherein a first fan-shaped valve core 151 and a second fan-shaped valve core 152 are provided on the connecting sleeve 15, and the first fan-shaped valve core 151 corresponds to the water inlet 111, and the second fan-shaped valve core 152 corresponds to the water outlet 121.

Through the above structure, it is achieved that when the smart water meter is controlled to be closed, the water inlet 111 and the water outlet 121 of the water meter can be blocked with two valve cores at the same time, thereby improving the sealing performance and preventing water leakage due to changes in water pressure. The detection accuracy of the flow sensor 2 is improved, and the problem of inaccurate user bills is avoided. Even if one valve core is worn and damaged, it can still be used normally, meeting the purpose of long-term use. In addition, the structure is stable and easy to operate, and it has certain practical value.

The specific operation is as follows: the platform collects flow information through the flow sensor 2, and accurately calculates the user's water consumption through an intelligent algorithm. When the water balance is insufficient, the platform automatically sends a text message to the user, prompting him to pay attention to the water consumption and pay the bill in time. The user can view the real-time changes in water consumption through the platform, and can complete the payment through the platform. If the water meter detects that the user's bill is in arrears, the platform will issue an instruction to the motor 4, and then the motor 4 will start, and then the first gear 41 will drive the valve stem 14 to rotate through the second gear 42, and then the first fan-shaped valve core 151 and the second fan-shaped valve core 152 will be blocked at the water inlet 111 and the water outlet 121 respectively to cut off the water flow. Then the user can complete the water balance query, payment, and on/off operation through the supporting platform, turn on the water meter, and use it.

Please refer to Figures 2 and 3. A cover plate 17 is movably connected near the upper end of the valve stem 14. The side edge of the cover plate 17 is stuck in the groove of the inner wall of the upper shell 12. The cover plate 17 is used to separate the inner cavity of the upper shell 12 from top to bottom, and the first gear 41 and the second gear 42 used for transmission are protected. The connecting sleeve 15 is movably connected with an impeller 16. The upper side of the outer wall of the upper shell 12 is provided with a motor 4. The output end of the motor 4 is provided with a first gear 41. The first gear 41 is meshed and connected with the second gear 42, and the second gear 42 is provided on the valve stem 14. At the upper end, the motor 4, the first gear 41 and the second gear 42 cooperate with each other to provide a driving force for the rotation of the valve stem 14. A filter cartridge 113 is provided between the water inlet 111 and the water inlet joint 112. The filter cartridge 113 is used to block foreign particles in the water and improve the water quality. A flow sensor 2 is provided near the motor 4, and the flow sensor 2 is electrically connected to the instrument panel 3. The flow sensor 2 is used to periodically accumulate the water flow and send the collected data to the remote metering system for metering so as to calculate the user's water fee.
