[0001] This application relates to the field of rotary vane water meter technology, and more specifically to a vertical rotary vane water meter. Background Technology

[0002] Rotary vane water meters achieve accurate measurement by driving the impeller to rotate through water flow. Depending on the installation method, rotary vane water meters include vertical rotary vane water meters, which are flow measurement devices suitable for vertical installation scenarios.

[0003] The specification drawing Figure 5 of the patent document (CN110702184B) discloses a vertical rotary vane water meter, including a base casing, a mechanism assembly for measuring water flow disposed in the base casing, and a valve control device connected to the outlet pipe for controlling the opening or closing of the outlet pipe. It is evident that the valve control device is arranged horizontally, the mechanism assembly is arranged vertically, and the valve control device is located between the outlet pipe and the mechanism assembly. Although selective water discharge from the outlet pipe can be achieved through the valve control device, the installation of the valve control device is relatively inconvenient due to its location between the outlet pipe and the mechanism assembly, and the limited space between the outlet pipe and the mechanism assembly. During the assembly and disassembly of the valve control device, the wrist of the assembler is prone to interference with the mechanism assembly.

[0004] Therefore, there is a need for a vertical rotary water meter in which both the valve control device and the detection and metering device are arranged vertically, and the valve control device is easier to disassemble and assemble. Summary of the Invention

[0026] An illustrative vertical rotary water meter, for reference. Figures 1 to 3 A preferred embodiment of the present invention provides a vertical rotary vane water meter, comprising a housing 10, a detection and metering device 20, and a valve control device 30.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the outer shell 10 has two vertical portions 101, two horizontal portions 102, and a connecting portion 103. The two vertical portions 101 are arranged coaxially and face opposite directions. One end of each vertical portion 101 facing each other is connected to the corresponding horizontal portion 102. The connecting portion 103 is connected to both horizontal portions 102. Each vertical portion 101 has a first channel 1011, and each horizontal portion 102 has a second channel 1021. The connecting portion 103 has a receiving cavity 1031. The two ends of the second channel 1021 are respectively connected to the receiving cavity 1031 and the corresponding first channel 1011.

[0028] It should be noted that one of the vertical sections 101 is connected to an external water inlet pipe, and the other vertical section 101 is connected to an external water outlet pipe. The horizontal section 102 provides space for the vertical arrangement of the valve control device 30, and the connecting section 103 and its accommodating cavity 1031 provide space for the vertical placement of the detection and metering device 20. Compared to the prior art, this application has the advantage that both the valve control device 30 and the detection and metering device 20 are vertically arranged, making it more convenient to assemble and disassemble the valve control device 30.

[0029] In addition, in this embodiment, a vertical portion 101 adjacent to a horizontal portion 102 connected to the valve control device 30 is connected to an external water outlet pipe. Furthermore, the detection and metering device 20 is vertically arranged and connected to the junction portion 103, with one end of the detection and metering device 20 extending into the receiving cavity 1031.

[0030] It should be noted that the external water source flows into the first channel 1011 in one of the vertical parts 101 through the external water inlet pipe, and then flows into the receiving cavity 1031 of the confluence part 103 along the second channel 1021 of the horizontal part 102, thereby driving the detection and metering device 20 to count and obtain the water flow rate. Subsequently, the water source flows into the external water outlet pipe from the first channel 1011 of the other horizontal part 102 after passing through the valve control device 30 along the second channel 1021 on the other horizontal part 102.

[0031] In addition, such as Figure 2As shown, the valve control device 30 includes a valve body 301 and an actuator 302. The valve body 301 is rotatably installed in the second channel 1021 on the horizontal part 102. One end of the valve body 301 has a rotating part 3011, and the rotating part 3011 extends out of the horizontal part 102. The actuator 302 is vertically arranged and installed on the horizontal part 102, and the actuator 302 is power-connected to the rotating part 3011. The actuator 302 is located on one side of the detection and measurement device 20.

[0032] It should be noted that by arranging the valve control device 30 on the horizontal part 102 close to the external water outlet pipe, conditions are provided for the actuator 302 to act and the valve body 301 to close the second channel 1021 after the prepaid amount in the user account is used up.

[0033] Furthermore, to install the valve body 301 in the second channel 1021, as Figure 1 and Figure 2 shown, the housing 10 includes an inlet and outlet housing 104 and a metering housing 105. The mating part 103 is provided on the metering housing 105. The vertical part 101 and the horizontal part 102 are provided on the inlet and outlet housing 104. The inlet and outlet housing 104 and the metering housing 105 are detachably connected by means of bolt connection. The first channel 1011 and the second channel 1021 on the inlet and outlet housing 104 are in the shape of "儿". The accommodating cavity 1031 includes a cylindrical part 1031A and two inclined parts 1031B. The two inclined parts 1031B are located at one end of the cylindrical part 1031A close to the inlet and outlet housing 104. One end of the inclined part 1031B is communicated with the corresponding second channel 1021, and the other end of the inclined part 1031B is communicated with the cylindrical part 1031A. The detection and measurement device 20 extends into the cylindrical part 1031A.

[0034] It should be noted that in the initial state, the inlet and outlet housing 104 and the metering housing 105 are in a separated state. After the assembly personnel install the valve body 301 into the second channel 1021, the inlet and outlet housing 104 and the metering housing 105 are bolt-connected. It should also be emphasized that the bolts used to connect the inlet and outlet housing 104 and the metering housing 105 are horizontally arranged, providing conditions for more convenient loosening of the bolts when the valve body 301 needs to be cleaned and replaced due to reasons such as sediment blockage.

[0035] Furthermore, as Figure 2As shown, the detection and measurement device 20 includes a filter screen 201, an impeller box 202, an impeller shaft 203, and a counting structure 204. The filter screen 201 has a cavity 2011 with a plurality of sieve holes (not shown in the figure). The impeller box 202 extends into the filter screen 201. The impeller shaft 203 is rotatably mounted in the impeller box 202. One end of the impeller shaft 203 away from the filter screen 201 is poweredly connected to the counting structure 204. A plurality of blades 2031 are fixedly connected to the impeller shaft 203.

[0036] More specifically, such as Figure 2 and Figure 3 As shown, the impeller box 202 has an impeller cavity 2021, and the side wall of the impeller cavity 2021 has a plurality of water inlets 20211 and a plurality of water outlets 20212.

[0037] It should be noted that in this application, the impeller shaft 203 and the counting structure 204 are powered by gear transmission. The filter screen 201 is provided to prevent large particles of mud and sand from passing through the filter screen 201 and flowing into the impeller box 202, thus avoiding wear on the blades 2031 on the impeller shaft 203. When water flows through the sieve holes on the filter screen 201 and into the impeller cavity 2021 through the inlet 20211 on the impeller box 202, the water impacts the blades 2031 and drives the impeller shaft 203 to rotate. The top of the impeller shaft 203 is then powered by the counting structure 204 through gear transmission. Subsequently, the water flows out from the outlet 20212 of the impeller box 202 and flows along the second channel 1021 and the first channel 1011 to the external water outlet pipe.

[0038] Furthermore, since the impeller shaft 203 of each of the vertical rotary water meters may have assembly and processing errors, the difference between the water consumption count of the counting structure 204 and the actual water consumption may be slightly less than the rated range. In view of this, the bottom wall of the impeller cavity 2021 has a fine adjustment hole 20213, and a fine adjustment structure 40 is rotatably installed on the bottom of the impeller box 202.

[0039] Specifically, the fine-tuning structure 40 includes a rotating component 401 and a fastener 402. The rotating component 401 has a fan-shaped groove 4011 and a skirt portion 4012. The bottom wall of the impeller cavity 2021 also has a threaded hole (not shown in the figure). The fastener 402 passes through the fan-shaped groove 4011 and is screwed into the threaded hole to press the rotating component 401 or separate from the rotating component 401. When the rotating component 401 rotates a predetermined angle, the skirt portion 4012 exposes or blocks the fine-tuning hole 20213.

[0040] It should be noted that by loosening the fastener 402 and rotating the rotating part 401, the skirt part 4012 is exposed or partially or completely blocked by the fine-tuning hole 20213. When the skirt part 4012 exposes the fine-tuning hole 20213, some water can still flow into the impeller cavity 2021 from the fine-tuning hole 20213, thereby achieving fine-tuning of the flow rate entering the impeller cavity 2021 per unit time.

[0041] Furthermore, since the horizontal portion 102 and the vertical portion 101 are arranged vertically, that is, the first channel 1011 and the second channel 1021 are arranged vertically, the water flow needs to pass through a corner when it flows in. To improve the connection strength of the two horizontal portions 102, such as Figure 1 As shown, the inlet / outlet shell 104 also includes a thin-walled connecting section 106, which is located between the two horizontal sections, and both ends of the thin-walled connecting section are respectively connected to the two horizontal sections.

[0042] It should be added that the reason for using a thin-walled connecting section 106 is that both the inlet / outlet shell 104 and the metering shell 105 are made of copper. Since copper is relatively expensive, making the connecting portion between the two horizontal sections thin-walled helps reduce the amount of copper used while still meeting strength requirements.

[0043] Furthermore, for ease of illustration during installation, such as Figure 1 As shown, the thin-walled connecting section 106 is provided with a flow direction marking protrusion 1061 and a number protrusion. The flow direction marking protrusion 1061 is in the shape of an arrow. In this application, the number protrusion is the number "15", which represents that the radial dimension of the first channel 1011 is 15mm.

[0044] In summary, the vertical rotary vane water meter described in the embodiments of this application is explained, which provides advantages such as the valve control device and the detection and metering device being arranged vertically, and the valve control device being easier to disassemble and assemble.

[0045] It is worth mentioning that, in this embodiment, the vertical rotary vane water meter has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the vertical rotary vane water meter provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
