In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] 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.

[0025] Therefore, refer to Figure 1 , Figure 3 and Figure 4 The utility model provides a flow measurement pipe network commutator, including a commutation support frame 100 fixedly arranged on the ground and a water bucket 200 with an opening upward, a support platform 101 is arranged on the top of the commutation support frame 100, a group of vertical outer spherical bearings 300 are symmetrically arranged on the upper surface of the support platform 101 through a fixed frame, a group of embedded columns 201 are fixedly connected on both sides of the water bucket 200, the embedded columns 201 are correspondingly embedded in the corresponding vertical outer spherical bearings 300 with a seat and can rotate freely, an opening is arranged on the surface of the support platform 101, a flow receiving and reversing box 400 is fixedly connected to the lower surface of the support platform 101, the flow receiving and reversing box 400 is connected to the opening, a group of water outlets 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 corresponding range of scales 600 at the bottom.

[0026] Specifically, the water bucket 200 is in an inverted triangle shape, with both the upper and lower ends being open, and a water pipe 700 is fixedly provided on the upper portion of the upper opening of the water bucket 200 .

[0027] Specifically, the lower end of the water bucket 200 opens out of an opening.

[0028] 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.

[0029] For details, please refer to Figure 2 A baffle plate 401 is disposed in the middle of the flow-bearing and reversing box 400 , and the baffle plate 401 divides the flow-bearing and reversing box 400 into two.

[0030] For details, please refer to Figure 4A group of pneumatic drive components 800 are also fixedly and symmetrically arranged on the upper surface of the support platform 101. The pneumatic drive components 800 and a group of vertical spherical bearings 300 are arranged perpendicular to each other. The pneumatic drive components 800 include a group of pneumatic support frames 801 fixed to the upper surface of the support platform 101. A cylinder 802 is fixedly arranged on the pneumatic support frames 801 horizontally on the upper surface of the support platform 101. The other end of the cylinder 802 is movably connected to a cylinder straight connecting rod 803. The other end of the cylinder straight connecting rod 803 is movably connected to a reversing ring 804. The reversing ring 804 is fixedly connected to the water bucket 200 through a connecting rod.

[0031] For details, please refer to Figure 3 , a flat plate 202 is provided inside the water bucket 200. When the water flow is put into the water bucket 200, the flat plate 202 is used to smooth the speed of the water flow and prevent large-scale splashing.

[0032] During use, water flows from the water pipe 700 into the water bucket 200, flows out from the opening at the bottom of the water bucket 200, 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.

[0033] When reversal is required, the pneumatic drive component is started, and the two symmetrical cylinders 802 move, presenting a movement state in which one end is pushed forward and the other end is pulled backward. After the movement of cylinder 802, it drives the cylinder direct connecting rod 803 to move, and the cylinder direct connecting rod 803 drives the reversing ring 804 to move. Since the cylinder direct connecting rod 803 and the joint of cylinder 802 and the reversing ring 804 are all movably connected, the movement of the overall reversing ring 804 is not affected, so that the water bucket 200 is driven by the fixed connecting rod to achieve the corresponding reversal. As for the reversing angle, the user can adjust the movable range of the cylinder joint according to the actual situation.

[0034] The utility model provides a flow measurement pipe network commutator, which realizes automatic reversing of a water bucket through a pneumatic drive component in cooperation with a vertical spherical bearing with a seat. 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 scale. Compared with the prior art method of pushing a water tank to achieve reversal, the utility model realizes semi-automatic reversal, and the coordination between components improves the speed of reversal, solving the problem that the traditional method requires the scale at the water outlet to be pushed by a cart for replacement when replacing the 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 scale.

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.
