As a new type of water meter, ultrasonic water meter has the advantages of high measurement accuracy and fast response speed, but it also requires a stable environment for flow testing.

[0003] In the specific water meter measurement link, the basic measurement process is: water release - when the pipe network is delivering water, the ultrasonic water meter performs initial flow measurement - the end of the pipe network performs terminal measurement of the amount of water flowing through - compare the difference between the initial measurement value and the terminal measurement value to give the measurement accuracy. Specifically in the terminal measurement link of the amount of water flowing through, due to the inconsistency of the pipe network diameter in the measurement link, the scale needs to be replaced according to the actual situation in order to improve the measurement accuracy. The traditional method requires the scale at the drain outlet to be pushed by a cart for replacement, which is cumbersome and difficult to operate. At the same time, frequent pushing will also cause damage to the metering components at the bottom of the scale. Summary of the invention

[0016] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0019] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0020] In the terminal measurement link of the water flow, due to the inconsistent diameter of the pipe network in the measurement link, it is necessary to replace the scale according to the actual situation in order to improve the measurement accuracy. The traditional method requires using a cart to push the scale at the drain outlet for replacement, which is cumbersome and difficult to operate. At the same time, frequent pushing will also cause damage to the metering components at the bottom of the scale.

[0021] Therefore, refer to Figure 1 and Figure 2The utility model provides a large flow measurement network commutator, including a reversing support frame 100 fixedly arranged on the ground and a water pipe 200 fixedly connected to the reversing support frame 100, a water bucket 300 is movably connected to the water outlet end of the water pipe 200, the water bucket 300 is movably connected to the water pipe 200 and can rotate around the water pipe 200, a flow receiving and reversing box 400 is arranged on the reversing support frame 100, the bottom opening of the water bucket 300 is connected to the flow receiving and reversing box 400, a group of water flow ports at the bottom of the flow receiving and reversing box 400 are connected to water receiving boxes 500 of different ranges, and a group of water receiving boxes 500 are each provided with a scale 600 of a corresponding range at the bottom.

[0022] For details, see Figure 2 The water bucket 300 is in the shape of an inverted fan arc with an opening at the lower end, thereby preventing the splashing of a large-diameter flow.

[0023] Specifically, the bottom of the flow-bearing and reversing box 400 corresponds to two water outlets, which are connected to two water receiving boxes 500 with different measuring ranges and two measuring scales 600 with different measuring ranges.

[0024] Specifically, a baffle plate is disposed in the middle of the flow-bearing and reversing box 400 , and the baffle plate divides the flow-bearing and reversing box 400 into two parts.

[0025] Furthermore, a group of pneumatic drive components 700 are symmetrically fixed on the reversing support frame 100, and the pneumatic drive components 700 include a group of pneumatic support frames 701 fixed on the reversing support frame 100, and a cylinder 702 is fixedly arranged on the group of pneumatic support frames 701 horizontally on the upper surface of the reversing support frame 100, and the other end of the cylinder 702 is movably connected to a cylinder straight connecting rod 703, and the other end of the cylinder straight connecting rod 703 is movably connected to the outer peripheral surface of the water bucket 300.

[0026] During use, water flows from the water pipe 200 into the water bucket 300, flows out from the opening at the bottom of the water bucket 300, flows into the corresponding flow channel of the flow receiving and reversing box 400, flows into the corresponding water receiving box 500, and is weighed by the measuring scale 600 set at the bottom.

[0027] When reversal is required, the pneumatic drive component is started, and the two symmetrical cylinders 702 move, presenting a movement state in which one end is pushed forward and the other end is pulled backward. After the movement of cylinder 702, it drives the cylinder direct connecting rod 703 to move, and the cylinder direct connecting rod 703 drives the water bucket 300 to move. Since the cylinder direct connecting rod 703 and the joint of the cylinder 702 and the outer peripheral wall of the water bucket 300 are all movably connected, it does not affect the movement of the entire water bucket 300, thereby achieving the corresponding reversal. As for the reversal angle, the user can adjust the movable range of the cylinder joint according to actual conditions.

[0028] The utility model provides a flow measurement pipe network reversing device, which realizes automatic reversing of a water bucket through a pneumatic driving component. After flowing through the water bucket, water flows into a corresponding water receiving box from an opening at the lower end, and is measured again by a corresponding measuring scale. Compared with the prior art method of pushing a water tank to realize reversing, the utility model realizes semi-automatic reversing, and the coordination between components improves the reversing speed, which solves the problem that the traditional method needs to push the measuring scale at the water outlet by a cart when replacing the measuring scale, which is cumbersome and difficult to operate, and the frequent pushing may also cause damage to the metering component at the bottom of the measuring scale. At the same time, the reversing water bucket provided by the utility model adopts an inverted fan arc shape with an opening at the lower end, which prevents splashing of large-diameter flow.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
