The ends of the first cone tube 10 and the second cone tube 11 close to each other are respectively inserted into the water inlet and the water outlet of the water meter 8, and then connected to the water meter 8. The ends of the first cone tube 10 and the second cone tube 11 away from each other are connected to two detection boxes 2. After the water in the detection box 2 with a high water level enters the water meter 8 through the first cone tube 10 and the second cone tube 11, it flows into the detection box 2 with a lower water level on the other side. The water volume change in the detection box 2 is observed by a liquid level meter. By measuring the unit time of the detection box 2 The water volume change in the water meter 8 is compared with the flow rate of the water meter 8, so as to detect and calibrate the water meter 8. A bracket 12 is installed on one side of the support plate 9. The bracket 12 is L-shaped. A movable frame 13 is slidably installed on the bracket 12. The movable frame 13 is connected to the second cone tube 11. An electric push rod 14 is installed on the bracket 12. The output shaft of the electric push rod 14 is connected to the movable frame 13. After the electric push rod 14 is started, the movable frame 13 is pushed to slide on the bracket 12, thereby making the second cone tube 11 close to or away from the first cone tube 10. When in use, the electric push rod 14 is started to shorten its output shaft. Then, the movable frame 13 is driven to move on the top of the bracket 12, so that the second cone tube 11 is away from the first cone tube 10, and the water inlet and the water outlet at both ends of the water meter 8 are aligned with the first cone tube 10 and the second cone tube 11, and the electric push rod 14 is started to move the second cone tube 11 toward the first cone tube 10, until the first cone tube 10 and the second cone tube 11 are inserted into the water inlet and the water outlet at both ends of the water meter 8, and then the water flow detection and verification of the water meter 8 can be started. After the detection is completed, the electric push rod 14 is started to move the second cone tube 11 away from the first cone tube 10, so that the water meter 8 can be removed conveniently.

[0027] By setting the bottom plate 1 and the detection box 2, the electric push rod 14 is used to push the movable frame 13 to move along the bracket 12, so that the second cone tube 11 is close to the first cone tube 10, which facilitates the water meter 8 to be fixed between the first cone tube 10 and the second cone tube 11, improves the connection speed of the pipeline, facilitates the disassembly and assembly of the water meter 8, and is conducive to improving the batch verification efficiency of the water meter 8.

[0028] Embodiment 2:

[0029] A rubber layer is fixedly installed on the surface of the first cone tube 10 and the second cone tube 11. When the first cone tube 10 and the second cone tube 11 are inserted into the water inlet and the water outlet of the water meter 8, the rubber layer will be squeezed and deformed, and the pipe connection will be sealed through the rubber layer to prevent water leakage from affecting the detection accuracy.

[0030] By providing a rubber layer on the surface of the first cone tube 10 and the second cone tube 11, it is convenient to seal the pipe connection to prevent water leakage from affecting the detection accuracy.

[0031] Embodiment 3:

[0032] like Figure 3-4 As shown, a first connecting tube 15 is installed on one side of the second cone tube 11, one end of the first connecting tube 15 passes through the mobile frame 13 and is connected to the corresponding detection box 2, a limiting ring 16 is fixedly installed on the first connecting tube 15, and a reset spring 17 is sleeved on the first connecting tube 15, one end of the reset spring 17 is connected to the second cone tube 11, and the other end is connected to the mobile frame 11, and the first connecting tube 15 is limited by the limiting ring 16 to prevent the first limiting tube 15 from escaping from the mobile frame 13. When in use, the mobile frame 13 moves to drive the reset spring 17 and the first connecting tube 15 to move, and when the second cone tube 11 is completely After being inserted into the water inlet or outlet of the water meter 8, if the movable frame 13 continues to move toward the side close to the water meter 8, the reset spring 17 will be compressed. The reset spring 17 shortens itself, so that the second cone tube 11 and the water meter 8 maintain elastic contact, that is, before the reset spring 17 reaches the compression limit, the force between the second cone tube 11 and the water meter 8 changes evenly without drastic changes, thereby preventing the movable frame 13 from moving too much and causing excessive force changes, thereby causing damage to the rubber layer on the surface of the first cone tube 10 and the second cone tube 11, thereby helping to extend the service life of the first cone tube 10 and the second cone tube 11.

[0033] By providing the first connecting tube 15, the limiting ring 16 and the return spring 17, the movable frame 13 is elastically connected to the second cone tube 11, which can buffer the pressure between the second cone tube 11 and the water meter 8, which is beneficial to prolonging the service life of the first cone tube 10 and the second cone tube 11, and thus facilitating the maintenance and use of the device.

[0034] Embodiment 4:

[0037] Example 5:

[0038] As shown Figure 1-3 in the figure, a rigid pipe 5 is installed on one side of the first tapered pipe 10 and is connected to it. A water pump 6 is installed at one end of the rigid pipe 5. A "U"-shaped transparent water pipe 4 is vertically installed at one end of the water pump 6. One end of the transparent water pipe 4 is connected to the corresponding detection box 2. The water in the detection box 2 is pumped through the water pump 6 and the transparent water pipe 4, and then discharged into the first tapered pipe 10 through the rigid pipe 5, so that the water enters the water meter 8. The transparent water pipe 4 is arranged in a vertical "U" shape, which is convenient for observing whether there are bubbles in the transparent water pipe 4, and makes the bubbles in the transparent water pipe 4 stay at the highest point of the transparent water pipe 4, preventing the bubbles from entering the water meter 8 and affecting the detection accuracy of the water meter 8.

[0039] By setting the "U"-shaped transparent water pipe 4, the rigid pipe 5 and the water pump 6, it is convenient to discharge the water in the detection box 2 on one side into the water meter 8, convenient for observing whether there are bubbles in the transparent water pipe 4, and making the bubbles in the transparent water pipe 4 stay at the highest point, preventing the bubbles from entering the water meter 8 and affecting the detection accuracy of the water meter 8.

[0040] Example 6:

[0041] As shown Figure 1-4 in the figure, a bellows 7 is installed at one end of the first connecting pipe 15. The bellows 7 is a flexible pipe. The other end of the bellows 7 is connected to the corresponding detection box 2. The water in the water meter 8 is discharged into the detection box 2 through the bellows 7. The bellows 7 moves along with the first connecting pipe 15 and can bend accordingly.

[0042] By setting a bellows 7 at one end of the first connecting pipe 15 and connecting the second tapered pipe 11 to the detection box 2 through the bellows 7, it is convenient for the water in the water meter 8 to be discharged and enter the detection box 2.

[0043] Working principle: Corresponding valves are installed on each pipeline, which will not be elaborated here. When in use, start the electric push rod 14 to shorten its output shaft, and then drive the moving frame 13 to move on the top of the bracket 12, so that the second tapered pipe 11 moves away from the first tapered pipe 10. Align the water inlet and outlet at both ends of the water meter 8 with the first tapered pipe 10 and the second tapered pipe 11. Start the electric push rod 14 to make the second tapered pipe 11 move towards the first tapered pipe 10 until the first tapered pipe 10 and the second tapered pipe 11 are inserted into the water inlet and outlet at both ends of the water meter 8. After the water in the detection box 2 with a higher water level enters the water meter 8 through the first tapered pipe 10 and the second tapered pipe 11, it flows into the detection box 2 on the other side with a lower water level. Observe the change of the water volume in the detection box 2 through the liquid level gauge. Compare the change of the water volume in the detection box 2 per unit time with the flow rate displayed by the water meter 8, so as to detect and calibrate the water meter 8. After the detection is completed, start the electric push rod 14 to make the second tapered pipe 11 move away from the first tapered pipe 10, so as to facilitate the removal of the water meter 8.
