A vertical water meter is a vertically installed water meter. A vertical water meter can be calibrated by a water meter calibration device. During calibration, the vertical water meter needs to be fixed on the calibration pipeline of the water meter calibration device. Currently, when calibrating vertical water meters, vertical water meters are often installed on the calibration pipeline manually. During installation, the placement of the water meter is first determined, and then clamped by a meter clamp. It is troublesome to manually install a vertical water meter on a meter clamp, and there is also the problem of low efficiency in the manual installation of vertical water meters. Summary of the invention

[0008] Furthermore, the lower support plate is provided with two side limit plates on one side of the positioning hole.

[0009] Furthermore, the rotating table is an electric rotating table.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model adds a rotating conveying mechanism to the original vertical water meter calibration device, and improves the applicability of the meter clamp, which makes the clamping of the vertical water meter very simple and can effectively improve the calibration efficiency. When calibrating the vertical water meter, the staff first places the vertical water meter on the positioning component of the rotating conveying mechanism. When placing the vertical water meter, the upper support plate is first moved upward to a certain height, and then the connecting pipe at the lower end of the vertical water meter is inserted into the positioning hole of the lower support plate, so that the vertical water meter is installed on the lower support plate, and at the same time, the shell connecting section of the vertical water meter is placed on both sides of the lower support plate. The upper support plate is moved downwards, and the connecting pipe at the upper end of the vertical water meter is inserted into the positioning hole of the upper support plate, thus completing the work of placing the vertical water meter on the rotating column; when clamping and calibrating the meter, the rotating column is rotated by the rotating table to rotate one of the vertical water meters on both sides of the rotating column to the meter clamping position between the water outlet pipe and the telescopic tube, and the lower support plate and the upper support plate are aligned with the telescopic tube up and down. At this time, the cylinder on the meter clamp drives the telescopic tube to move upwards, and the lower flange of the telescopic tube contacts the connecting pipe at the lower end of the vertical water meter and pushes the vertical water meter to move upwards until the vertical water meter is in contact with the connecting pipe at the lower end of the vertical water meter. The top surface of the connecting pipe at the upper end of the vertical water meter is in close contact with the upper flange of the outlet pipe. Rubber pads are installed on the upper flange and the lower flange to further form a good sealing effect, thus completing the meter clamping work. It can be seen from the above that the manual installation of the vertical water meter on the meter clamp can be avoided by setting up a rotating conveying mechanism. More importantly, it can speed up the calibration efficiency of the vertical water meter. One of the main reasons for improving the calibration efficiency is that when a vertical water meter on the rotating column is being calibrated, the staff can remove the other calibrated vertical water meter and install a new uncalibrated vertical water meter. In this way, during the calibration, During the calibration process, we install the new vertical water meter to be calibrated. In actual application, a water meter calibration platform may need to install multiple meter clamping devices, and each meter clamping device includes a rotating conveying mechanism. The utility model installs the rotating conveying mechanism, and the staff can complete the work of removing the calibrated vertical water meter on the opposite side of the rotating column and installing the uncalibrated vertical water meter during the calibration of the vertical water meter. Compared with the prior art that the vertical water meter needs to wait until a group of vertical water meters are calibrated before unloading and installing the meter, the calibration efficiency of the vertical water meter is effectively improved.

[0016] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0017] A vertical water meter calibration device comprises a water meter calibration platform 1, wherein the water meter calibration platform 1 comprises a back plate 2. The water meter calibration platform 1 of the utility model is used to install and fix a vertical water meter that needs to be calibrated, and input water to the vertical water meter that needs to be calibrated through a water meter calibration pipeline. In the prior art, the vertical water meter can be fixed on the water meter calibration pipeline of the water meter calibration platform 1 by a meter clamp 17 during calibration, and a plurality of vertical water meter fixing positions can be arranged at intervals on the water meter calibration pipeline, and a meter clamp 17 is installed on each vertical water meter fixing position for fixing the vertical water meter. The utility model is improved on the basis of the water meter calibration platform 1 of the vertical water meter calibration device in the prior art, and solves the current problems of being troublesome in fixing the vertical water meter to the meter clamp 17 and the low efficiency of vertical water meter calibration.

[0018] The water meter calibration platform 1 is provided with a meter clamping device, which includes a water meter calibration pipeline and a meter clamp 17 fixedly installed on the back plate 2. The meter clamp 17 is a prior art. In the present utility model, the meter clamp 17 can be a pneumatic meter clamp 17, which is driven by a cylinder when in motion. In the present utility model, a plurality of meter clamping devices can be arranged at intervals on the water meter calibration platform 1 to facilitate the calibration of a plurality of vertical water meters at the same time. When there are a plurality of meter clamping devices, the water meter calibration pipelines of each two adjacent meter clamping devices are connected.

[0019] The water meter calibration pipeline includes a water inlet pipe 3 and a water outlet pipe 4. A water hole is provided in the middle of the meter clamp 17. A telescopic pipe 5 is slidably installed in the water hole. The telescopic pipe 5 can be extended and retracted by a cylinder drive to achieve the action of clamping and removing the meter. The rear end of the water hole in the middle of the meter clamp 17 is connected to the water inlet pipe 3. When the vertical water meter is installed between the telescopic pipe 5 and the water outlet pipe 4, water enters the water hole and the telescopic pipe 5 from the water inlet pipe 3 and then enters the connecting pipe of the vertical water meter, and finally flows out from the water outlet pipe 4.

[0020] A lower flange 6 is provided on the top of the telescopic tube 5, and a rubber pad is installed on the lower flange 6. The lower end surface of the water outlet pipe 4 is on the upper side of the telescopic tube 5 and is arranged opposite to the telescopic tube 5. An upper flange 7 is provided on the bottom of the water outlet pipe 4, and a rubber pad is installed on the upper flange 7. The outer peripheral edges of the upper flange 7 and the lower flange 6 of the utility model are both provided with annular bosses. By arranging the rubber pad, the sealing performance of the vertical water meter when being squeezed and fixed can be improved to prevent water leakage.

[0021] The meter clamping device also includes a rotating conveying mechanism, which includes a rotating table 8 installed on the water meter calibration platform 1, and a rotating column 9 is installed on the top of the rotating table 8. The rotating table 8 is a prior art. The rotating column 9 is fixedly installed on the rotating table 8. The rotating table 8 drives the rotating column 9 to rotate. The rotating table 8 is an electric rotating table. When used, we can set the electric rotating table to drive the rotating column 9 to rotate 180 degrees each time.

[0022] Positioning components are installed on both sides of the rotating column 9, and the positioning components on both sides are arranged oppositely. The positioning components include an upper support plate 10 and a lower support plate 11. Positioning holes 12 are respectively provided on the upper support plate 10 and the lower support plate 11. The positioning holes 12 can be designed to be similar to the diameter of the connecting pipe of the mass-produced vertical water meter. The upper support plate 10 is slidably installed on the rotating column 9, and the lower support plate 11 is fixedly installed on the rotating column 9. The lower support plate 11 can be detachably connected to the rotating column 9 by bolts. The lower support plate 11 is installed with two side limit plates 16 on one side of the positioning hole 12, and the bottom of the limit plate 16 is connected to the lower support plate 11 by glue. The utility model can limit the installation angle of the vertical water meter when it is installed on the lower support plate 11 by installing limit plates 16 on both sides on the lower support plate 11, and also prevent the vertical water meter from rotating after being installed on the lower support plate 11. The distance between the limit plates 16 on both sides is close to the width of the shell connecting section of the vertical water meter. By limiting the installation angle of the vertical water meter, when the vertical water meter is rotated to the clamping position, the camera 15 on the back plate 2 can face the instrument panel of the vertical water meter.

[0023] The rotating column 9 is provided with a slide groove 13 that cooperates with the upper support plate 10; the slide groove 13 is T-shaped, and one end of the upper support plate 10 is T-shaped and inserted into the slide groove 13. By setting the slide groove 13 in a T shape, the utility model can make the upper support plate 10 move up and down only along the slide groove 13, and the sliding is more stable.

[0024] The back plate 2 is provided with an inner groove 14 between the water inlet pipe 3 and the telescopic pipe 5. The utility model can avoid interference during the rotation of the rotating column 9 by providing the inner groove 14.

[0025] A camera 15 is installed on the upper side of the back plate 2. When the utility model is used, when the vertical water meter is rotated to the clamping position, the camera 15 can face the instrument panel of the vertical water meter and collect image information of the instrument panel.

[0026] The working process of this utility model:

[0027] When the utility model installs the vertical water meter on the rotating column 9, the upper support plate 10 is first moved upward to a certain height, and then the connecting pipe at the lower end of the vertical water meter is inserted into the positioning hole 12 of the lower support plate 11, so that the vertical water meter is installed on the lower support plate 11, and at the same time, the shell connecting section of the vertical water meter is placed between the limit plates 16 on both sides of the lower support plate 11, and then the upper support plate 10 is moved downward, and the connecting pipe at the upper end of the vertical water meter is inserted into the positioning hole 12 of the upper support plate 10, so that the process of placing the vertical water meter on the rotating column 9 is completed. When clamping the meter, the rotating column 9 is rotated 180 degrees by the rotating table 8, so that one of the vertical water meters on both sides of the rotating column 9 is rotated to the meter clamping position between the water outlet pipe 4 and the telescopic tube 5, and the lower support plate 11 and the upper support plate 10 are aligned with the telescopic tube 5 up and down. At this time, the cylinder on the meter clamp 17 drives the telescopic tube 5 to move upward, and the lower flange 6 of the telescopic tube 5 contacts the connecting pipe at the lower end of the vertical water meter and pushes the vertical water meter to move upward until the top surface of the connecting pipe at the upper end of the vertical water meter is in close contact with the upper flange 7 of the water outlet pipe 4. Rubber pads are installed on the upper flange 7 and the lower flange 6, which can further form a good sealing effect, so that the meter clamping work is completed. After the calibration of the vertical water meter on this side is completed, the rotating column 9 is rotated 180 degrees by the rotating table 8, so that the vertical water meter on this side is rotated out of the meter clamping position, and at the same time, the vertical water meter on the other side that has not been calibrated is rotated to the meter clamping position.
