Description

Technical Field

[0001] This application relates to the technical field of gas meter testing, and in particular to a gas meter value identification and testing device. Background Technology

[0002] The gas base meter is the core metering component of a gas meter, used to directly measure the flow rate of gas. It mainly consists of a housing, gas passage, metering device, display, metering circuit board, and battery. The gas base meter calculates gas consumption by measuring parameters such as the pressure difference and turbine rotation angle generated when gas flows within the meter body.

[0003] like Figure 1 As shown, gas meters typically have an inlet and an outlet. Currently, the gas meter is placed in the testing area, and then the inlet and outlet pipes are inserted. Gas is then introduced into the gas meter through the inlet pipe, and the readings are manually taken and recorded to determine if there are any abnormalities in the meter readings. After a gas meter has been tested, the inlet and outlet pipes are removed, and a new gas meter is installed for testing. This method of testing gas meters is inefficient and affects the overall efficiency of gas meter testing. Utility Model Content

[0004] The purpose of this application is to provide a gas meter value identification and detection device to improve the overall detection efficiency of gas meters.

[0005] The gas meter value identification and detection device provided in this application adopts the following technical solution: it includes a detection platform, the detection platform is connected to a mounting plate, the mounting plate is slidably connected to an inlet pipe and an outlet pipe, the mounting plate is connected to a first driving member and a second driving member, the first driving member is used to drive the inlet pipe to slide in a direction closer to or farther from the detection platform, the second driving member is used to drive the outlet pipe to slide in a direction closer to or farther from the detection platform, and the detection platform is connected to a camera, the camera is used to correspond to the gas meter.

[0006] By adopting the above technical solution, the operator only needs to place the gas meter below the inlet and outlet pipes. The first driving component drives the inlet pipe to slide closer to the gas meter, so that the inlet end of the inlet pipe is engaged with the inlet port of the gas meter. The second driving component drives the outlet pipe to slide closer to the gas meter, so that the outlet end of the outlet pipe is engaged with the outlet port of the gas meter. The gas meter is clamped by the testing platform, the inlet pipe, and the outlet pipe, thereby improving the stability of the gas meter placed on the testing platform. Gas is introduced into the gas meter through the inlet pipe, and the gas inside the gas meter is discharged through the outlet pipe. The display of the gas meter shows the gas consumption, and the camera takes a picture and records the value displayed on the display to prevent errors caused by manual recording. After the camera finishes taking pictures, the first drive unit moves the intake pipe away from the gas meter, causing it to detach from the gas meter. The second drive unit moves the exhaust pipe away from the gas meter, causing it to detach from the gas meter as well. With the intake and exhaust pipes released from the gas meter, it can be removed from the testing station and replaced with a new, untested gas meter. This automated insertion and removal of the intake and exhaust pipes, along with automatic recording of the values ​​from each gas meter, reduces the operator's workload and improves the overall efficiency of gas meter testing.

[0007] Optionally, the testing platform is connected to a first positioning plate and two second positioning plates. The first positioning plate is located between the two second positioning plates. When the gas base meter simultaneously abuts against the first positioning plate and the two second positioning plates, the gas inlet of the gas base meter corresponds to the gas inlet pipe, and the gas outlet of the gas base meter corresponds to the gas outlet pipe.

[0008] By adopting the above technical solution, when placing the gas base meter, the gas base meter simultaneously abuts against the first positioning plate and two second positioning plates. The first positioning plate and two second positioning plates play a positioning role for the placement of the gas base meter, so that the gas inlet of the gas base meter corresponds precisely to the gas inlet pipe and the gas outlet of the gas base meter corresponds precisely to the gas outlet pipe, thereby improving the efficiency of placing the gas base meter.

[0009] Optionally, each of the two second positioning plates has a guide surface on one side facing each other, and the guide surface is located at the end of the second positioning plate away from the first positioning plate.

[0010] By adopting the above technical solution, the guide surface plays a guiding role in the installation of the gas base meter, enabling the surface of the gas base meter to quickly contact the first positioning plate and the two second positioning plates, thereby improving the installation efficiency of the gas base meter.

[0011] Optionally, a sealing ring is connected to the outer circumferential surface of the air intake pipe.

[0012] By adopting the above technical solution, the air intake pipe is inserted into the air intake port of the gas meter, the sealing ring is compressed and undergoes elastic deformation, the sealing ring applies force to the inner wall of the air intake port, and the sealing ring seals the gap between the air intake pipe and the gas meter, thereby improving the sealing performance.

[0013] Optionally, the outer surface of the sealing ring is provided with a guide ring surface, which is located at the end of the sealing ring closer to the detection table, and the radius of the guide ring surface gradually decreases towards the detection table.

[0014] By adopting the above technical solution, when the intake pipe moves towards the gas base meter, even if the intake pipe and the gas base meter's intake port are not completely aligned, the guide ring surface abuts against the inner wall of the intake port and drives the gas base meter to the corresponding position, making it easier for the intake pipe to be inserted into the gas base meter's intake port.

[0015] Optionally, there are several air intake pipes, which are spaced apart. The number of air intake pipes, air outlet pipes, the first driving component, and the second driving component are all the same. The detection stage is slidably connected to a carrier plate, and the detection stage is connected to a driving assembly. The driving assembly is used to drive the carrier plate to slide along the arrangement direction of the several air intake pipes. The camera is connected to the carrier plate.

[0016] By adopting the above technical solution, while one gas meter is being filled and photographed, the operator can install the gas meter to be tested below the other inlet pipe, thus preparing in advance. After the camera takes the picture, the drive component drives the carrier plate to slide, aligning the camera with the gas meter to be tested. This eliminates the need to wait for the gas meter installation time, thereby improving the overall efficiency of gas meter testing.

[0017] Optionally, the carrier plate is connected to an adjusting plate, the adjusting plate is connected to a bolt, the bolt is threaded with a nut, the adjusting plate is provided with a through hole for the bolt to pass through, the carrier plate is provided with a waist-shaped hole for the bolt to pass through, and the camera is connected to the adjusting plate.

[0018] By adopting the above technical solution, the nut is loosened, allowing it to separate from the adjusting plate. The bolt can then slide along the oblong hole, adjusting the height of the adjusting plate and the camera so that the camera aligns with the display screen of the gas meter.

[0019] Optionally, two bolts are connected to the adjusting plate, and the number of the waist-shaped holes, the through holes, and the nuts are the same as the number of bolts, with the two waist-shaped holes arranged in parallel.

[0020] By adopting the above technical solution, when the adjusting plate slides, the two bolts slide along the corresponding waist-shaped holes. The sliding cooperation between the bolts and the waist-shaped holes plays a guiding and limiting role in the sliding of the adjusting plate, thereby preventing the adjusting plate from rotating during the movement and improving the stability of the adjusting plate sliding.

[0021] Optionally, the drive assembly includes a guide rod connected to the testing table, a lead screw rotatably connected to the testing table, and a third drive member for driving the lead screw to rotate. The third drive member is connected to the testing table, the carrier plate is threadedly connected to the lead screw, and the carrier plate is slidably connected to the guide rod.

[0022] By adopting the above technical solution, the third driving component drives the lead screw to rotate, and the carrier plate slides along the length of the guide rod, so that the camera can sequentially detect different gas meters, thereby improving the overall detection efficiency of the gas meters.

[0023] Optionally, the mounting plate is connected to a plurality of laser sensors, the number of which is the same as the number of air intake pipes. The detection platform is connected to a controller. The laser sensors are used to sense the camera. The third driving component and the laser sensors are both electrically connected to the controller.

[0024] By adopting the above technical solution, when the camera moves to the laser sensor, the laser sensor outputs a signal to the controller. The controller receives the signal and outputs a signal to the third driving component, which then stops operating, thus stopping the camera's movement. At this time, the camera corresponds to the display screen of one of the gas meter base stations, improving the camera's efficiency in recording gas meter readings.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The system adopts automated insertion and removal of the inlet and outlet pipes, as well as automatic recording of the values ​​of each gas meter, which reduces the labor intensity of the operator and thus improves the overall efficiency of gas meter testing.

[0027] 2. When the air intake pipe is inserted into the air intake port of the gas meter, the sealing ring is compressed and undergoes elastic deformation. The sealing ring applies force to the inner wall of the air intake port, sealing the gap between the air intake pipe and the gas meter, thus improving the sealing performance.

[0042] The implementation principle of a gas meter value identification and detection device according to an embodiment of this application is as follows:

[0043] When placing the gas meter, it simultaneously abuts against the first positioning plate 31 and the two second positioning plates 32. The first positioning plate 31 and the two second positioning plates 32 position the gas meter, ensuring that the gas meter's inlet precisely aligns with the inlet pipe 4, and the gas meter's outlet precisely aligns with the outlet pipe 5.

The gas meter's display shows the gas consumption, and the camera 9 takes a picture and records the displayed value to prevent errors from manual recording. After camera 9 finishes taking a picture, the first drive component 21 drives the intake pipe 4 to slide away from the gas base meter, causing the intake pipe 4 to detach from the gas base meter. The second drive component 22 drives the exhaust pipe 5 to slide away from the gas base meter, causing the exhaust pipe 5 to detach from the gas base meter. The intake pipe 4 and exhaust pipe 5 are then released from the gas base meter. While one gas base meter is being inflated and photographed, the operator can install the gas base meter to be tested below the other intake pipe 4, preparing in advance. After camera 9 takes a picture, the drive component 7 drives the carrier plate 6 to slide, aligning camera 9 with the gas base meter to be tested. This eliminates the need to wait for the gas base meter installation time, thus improving the overall efficiency of gas base meter testing.
