[0034] Please refer to Figures 1 to 5 simultaneously. An embodiment of the present application provides a meter calibration device. The meter calibration device includes a meter calibration platform 10 and a meter calibration counter 20. On both sides of the meter calibration counter 20 along the second direction, there are respectively provided first support plates 21 for detachably installing the meter calibration platform 10. The meter calibration platform 10 is provided with a plurality of meter calibration components 11 along the first direction. A diversion pipe 12 is connected between adjacent meter calibration components 11. The meter calibration component 11 includes a first guide rail 111 and a plurality of clamping devices 112 slidably installed along the second direction on the first guide rail 111. The meter calibration counter 20 is further provided with a plurality of detection components 22 along the second direction. The detection component 22 includes a lifting device 221 and a plurality of induction elements 222 spaced along the first direction on the lifting device 221. The plurality of induction elements 222 correspond to the plurality of meter calibration components 11 one by one. The lifting device 221 is used to drive the induction element 222 to approach or move away from the meter calibration component 11 along the third direction.

[0035] By setting the meter calibration platform 10 and the meter calibration counter 20 to cooperate with each other, the meter calibration platform 10 is provided with a plurality of meter calibration components 11, and each meter calibration component 11 can respectively place a plurality of water meters 30; the meter calibration platform 10 is detachably installed on the meter calibration counter 20. After the water meter 30 completes the calibration process, the meter calibration platform 10 is disassembled, and the water meter 30 can be transferred to other devices together with the meter calibration platform 10 for subsequent processes, so as to save the time required for transferring the water meter 30; the lifting device 221 drives the induction element 222 to approach or move away from the meter calibration component 11 along the third direction, which can replace manual operation for placing and taking out the induction element 222 and reduce the alignment deviation caused by manual operation. The meter calibration efficiency of the meter calibration device is higher and the accuracy is higher.

[0036] In application, a water meter 30 is placed between adjacent clamping devices 112 of each meter calibration component 11. Placing the water meter 30 between adjacent clamping devices 112 can be operated by a robotic arm or manually. The two ends of the diversion pipe 12 are respectively connected to the clamping devices 112 at the ends of adjacent two meter calibration components 11. The plurality of diversion pipes 12 are arranged in a staggered manner, so that after all the meter calibration components 11 are filled with water meters 30, a passage is formed between all the water meters 30 for water flow to pass through.

[0037] Specifically, in an embodiment of the present application, the number of meter calibration components 11 is four, and each meter calibration component 11 can place five water meters 30. The number of diversion pipes 12 is three. It can be understood that in other embodiments, other numbers of meter calibration components 11 and diversion pipes 12 can be set according to production needs.

[0038] In one embodiment, please refer to Figures 1 to 5 The clamping device 112 includes a first driving device 1121, a seat body 1122 and a positioning tube 1123. The output end of the first driving device 1121 is connected to one side of the seat body 1122 along the second direction. The first guide rail 111 is slidably mounted with a first slider 113. The first slider 113 is connected to the seat body 1122. The positioning tube 1123 penetrates the seat body 1122 along the second direction. The end of the positioning tube 1123 has a notch 101 on the side away from the first guide rail 111 along the third direction.

[0039] In application, the first driving device 1121 can be a cylinder, which is controlled by a solenoid valve. There are two first guide rails 111, and a first slider 113 is connected to each side of the seat body 1122 along the first direction to ensure smooth sliding of the seat body 1122.

[0040] Specifically, the water meter 30 is penetrated by a sleeve 31, and the two ends of the sleeve 31 are respectively placed in two adjacent positioning tubes 1123 through the gap 101. The output end of the first driving device 1121 drives the connected seat body 1122 to move along the second direction, so that the water meter 30 can be tightly installed between adjacent clamping devices 112.

[0041] In one embodiment, please refer to Figures 1 to 6 The calibration platform 10 is also provided with two first joints 13, and the two first joints 13 are respectively connected to two of the multiple calibration components 11 located at the edge along the first direction with drainage tubes 14. The calibration counter 20 is also provided with two second joints 23 corresponding to the two first joints 13 one by one, and the two second joints 23 are slidably installed on the same one of the two first support plates 21 along the second direction.

[0042] In application, the drainage tube 14 is connected to the clamping device 112 located at the end of the calibration assembly 11 along the second direction, and the drainage tube 12 and each drainage tube 14 placed on the same side as the drainage tube 14 are respectively connected to a second driving device, which can be a cylinder. The second driving device is controlled by a solenoid valve, and the output end of the second driving device can move along the second direction to accommodate the installation of different models of drainage tubes 14 and 12.

[0043] In application, the second joint 23 is installed on the first support plate 21 through the second guide rail and the second slider. The second joint 23 is connected to the third drive device, which can be a cylinder. The third drive device is controlled by a solenoid valve, and the output end of the third drive device can move along the second direction.

[0044] In application, one of the two drain pipes 14 is used for water inlet, and the other of the two drain pipes 14 is used for water outlet. Connect the water source to the drain pipe 14 for water inlet, and the water flows through all the water meters 30 and then flows out from the drain pipe 14 for water outlet. During this process, the first joint 13 can limit and fix the drain pipe 14 to prevent the drain pipe 14 from shifting under the action of water pressure.

[0045] Specifically, when it is necessary to inject water into the water meter 30, the water source is connected from the drain pipe 14 for water inlet. After the water flows through each water meter 30 placed in the meter calibration assembly 11 where the drain pipe 14 is located, it flows into each water meter 30 placed in the adjacent meter calibration assembly 11 through the diversion pipe 12. After the water flows through each water meter 30 placed in the remaining meter calibration assemblies 11, it finally flows out from the drain pipe 14 for water outlet, so that the water can flow through all the water meters 30 in sequence.

[0046] Specifically, when it is necessary to drain the water in the water meter 30, the gas source is connected from the drain pipe 14 for water outlet. After the air flow passes through each water meter 30 placed in the meter calibration assembly 11 where the drain pipe 14 is located, it flows into each water meter 30 placed in the adjacent meter calibration assembly 11 through the diversion pipe 12. After the air flow passes through each water meter 30 placed in the remaining meter calibration assemblies 11, it finally flows out from the drain pipe 14 for water inlet, so that the air flow can drain the water in all the water meters 30 in sequence.

[0047] In one embodiment, please also refer to Figures 1 to 6 , the meter calibration counter 20 is further provided with a second support plate 24 and two locking members 25. The second support plate 24 is perpendicular to the first support plate 21. The locking members 25 are slidably mounted on the second support plate 24 along the third direction, and each locking member 25 is respectively used to lock the corresponding first joint 13 and second joint 23.

[0048] In application, the locking member 25 is mounted on the second support plate 24 through a third guide rail and a third slider. The locking member 25 is connected with a fourth driving device. The fourth driving device can be a cylinder. The fourth driving device is controlled by an electromagnetic valve. The output end of the fourth driving device can move along the third direction. By setting the locking member 25 to lock the first joint 13 and the second joint 23 for sealing, it is possible to prevent water leakage or air leakage at the connection between the first joint 13 and the second joint 23.

[0049] In one embodiment, please also refer to Figures 1 to 6 , the ends of the first joint 13 and the second joint 23 are both wedge-shaped, and the locking member 25 has grooves adapted to the ends of the first joint 13 and the second joint 23.

[0050] In application, the shapes of the first joint 13, the second joint 23 and the locking member 25 are simple, and the sealing effect is good.

[0052] In use, the electrical plug 15 is plugged into the electrical socket 26 to form an electrical connection between the meter calibration platform 10 and the meter calibration counter 20 , so that the meter calibration counter 20 can provide power to the meter calibration platform 10 .

[0053] In one embodiment, please refer to Figures 1 to 6 The calibration platform 10 is provided with first positioning members 16 on both sides along the second direction, and the first support plate 21 is provided with second positioning members 27 for the first positioning members 16 to be plugged in along the third direction.

[0054] In application, the calibration platform 10 can be moved to the calibration counter 20 by robot operation or manual operation. In one embodiment of the present application, the first positioning member 16 is a ring and the second positioning member 27 is a column. It can be understood that in other embodiments of the present application, the first positioning member 16 is a column and the second positioning member 27 is a ring.

[0055] Specifically, a proximity switch is installed at a position of the first support plate 21 near the second positioning member 27. When the proximity switch senses that the calibration platform 10 is placed on the calibration counter 20, it sends a control signal to each solenoid valve. The third driving device first drives the second connector 23 to move along the second direction until it is pressed against the first connector 13, and then the fourth driving device drives the locking member 25 to move along the third direction until the locking member 25 locks the first connector 13 and the second connector 23.

[0056] In one embodiment, please refer to Figures 1 to 6 The calibration counter 20 further includes a plurality of bearing assemblies 28 , which are rotatably mounted on the first support plate 21 adjacent to the second positioning member 27 .

[0057] In application, two bearing assemblies 28 are respectively provided on the outer periphery of each second positioning member 27. The two bearing assemblies 28 can respectively fine-tune the installation position of the calibration platform 10 along the first direction and the second direction to make the positioning between the first positioning member 16 and the second positioning member 27 more precise.

The transfer device can be a robot or a lifting device to conveniently place the meter calibration platform 10 into the meter calibration counter 20 or take the meter calibration platform 10 away from the meter calibration counter 20.

[0060] In one embodiment, please also refer to Figures 1 to 5 , the lifting device 221 includes a first frame 2211, a second frame 2212 and a plurality of corner pieces 2213.

The second frame 2212 is slidably installed in the first frame 2211. The plurality of corner pieces 2213 correspond to the plurality of sensing elements 222 one by one. One side of the corner piece 2213 is connected to the second frame 2212 and the other side is connected to the corresponding sensing element 222.

[0061] In an application, the light-emitting diode of the water meter 30 sends pulse data. The sensing element 222 can be an infrared receiver. The sensing element 222 is used to receive the pulse data sent by the water meter 30, and then the data is processed by a computer in the calibration software through wired data transmission.
