[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) By providing a swinging mechanism, the gas meter swings periodically back and forth in water, thereby changing the posture of the gas meter, enabling bubbles in each part to have the opportunity to be exposed, reducing the situation where bubbles are blocked, contributing to comprehensively and accurately detecting the sealing condition of the gas meter. At the same time, the swinging makes the movement trajectory of the bubbles in the water more obvious, forming a stronger visual contrast with the surrounding water body, facilitating observation and identification. Compared with the bubbles in static water, the bubbles during the movement process are more easily observed.

[0017] (2) By providing an intermittent rotation flow disturbing assembly, the rotation of the paddle is used to disturb the water flow, causing the water flow to periodically impact the surface of the gas meter. During the intermittent period of the water flow impact, the water around the gas meter is in a relatively static state, which is conducive to observing bubbles. When the water flow impacts, it can shorten the attachment time of the bubbles on the surface of the gas meter, preventing the bubbles from aggregating or fusing due to long-term attachment, and making it easier to identify small and separate bubbles.

[0018] (3) By providing a water flow vibration assembly, the up-and-down vibration of the vibration plate is used to transmit the vibration into the water, causing slight fluctuations in the water body around the gas meter. This kind of fluctuation can further interfere with the attachment of the bubbles on the surface of the gas meter, and can also continuously prompt the bubbles to detach from the surface of the gas meter during the intermittent period of the water flow impact. Moreover, the vibration helps to break the locally static areas that may form in the water body, making it easier for the bubbles to float to the water surface to be observed, thereby improving the comprehensiveness and accuracy of bubble detection.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The embodiments of the present invention provide three technical solutions, specifically including the following embodiments:

[0030] Embodiment 1

[0031] Please refer to Figures 1-5, a device specifically for detecting the sealing performance of gas meters, including a box body 1. There is clear water in the box body 1, and a gas meter 2 to be detected is arranged in the box body 1. The gas meter 2 is immersed in the clear water, gas is introduced into the gas meter 2, and it is observed whether there are bubbles generated around the gas meter 2 to judge the sealing performance of the gas meter 2 to be detected. An L-shaped plate 3 is fixed on one side of the box body 1, a cylinder 4 is fixed on the top of the L-shaped plate 3. The cylinder 4 is controlled by an external switch and is electrically connected to an external power supply. The output end of the cylinder 4 is fixed with a U-shaped plate 5. A groove 6 is opened on the top of the U-shaped plate 5. The air inlet of the gas meter 2 is communicated with an air inlet pipe 7, and the air outlet of the gas meter 2 is communicated with an air outlet pipe 8. The groove 6 is adapted to the sizes of the air inlet pipe 7 and the air outlet pipe 8. The air inlet pipe 7 and the air outlet pipe 8 are placed in the groove 6, and the air inlet pipe 7 and the air outlet pipe 8 can rotate in the groove 6. A swinging mechanism 9 for driving the gas meter 2 to swing is arranged on the U-shaped plate 5;

[0032] The swinging mechanism 9 includes two folding rods 91 fixed on the top of the U-shaped plate 5. A convex plate 92 is fixed between one ends of the two folding rods 91. A disc 93 is rotatably connected to one side of the convex plate 92. A cross plate 94 is fixed on one side of the convex plate 92. A motor 95 is fixed on the cross plate 94. The motor 95 is controlled by an external switch and is electrically connected to an external power supply. The motor 95 drives the disc 93 to rotate. The output end of the motor 95 is fixed to one side of the disc 93. A connecting column 96 is fixed on one side of the disc 93. A tooth fork 97 is rotatably connected to one side of the convex plate 92 through a pin shaft. A sliding groove 98 is formed through one side of the tooth fork 97. The connecting column 96 slides in the sliding groove 98. Two rod seats 99 are fixed on one side of the convex plate 92. The rod seats 99 are used to limit the tooth rod 910 so that the tooth rod 910 can only move left and right. A tooth rod 910 is slidably connected between the inner surfaces of the two rod seats 99. The tooth fork 97 meshes with the tooth rod 910. One side of the tooth rod 910 is fixed with an L-shaped rod 911. The bottom end of the L-shaped rod 911 is fixed with a first rack 912. A first gear 913 is fixed on the air outlet pipe 8. The first rack 912 meshes with the first gear 913. When the tooth fork 97 swings, it can drive the tooth rod 910 to move left and right reciprocally.

[0033] By setting the swinging mechanism 9, the gas meter 2 swings periodically and reciprocally in the water, the swinging amplitude is ±45°, the swinging frequency is 0.5 Hz. The reciprocating swing changes the posture of the gas meter 2, enabling bubbles in all parts to have the opportunity to be exposed, reducing the situation where bubbles are blocked, which helps to comprehensively and accurately detect the sealing condition of the gas meter 2. At the same time, the swing makes the movement trajectory of the bubbles in the water more obvious, forming a stronger visual contrast with the surrounding water body, facilitating observation and identification. Compared with the bubbles in static water, the bubbles during the movement process are more easily observed.

[0034] Embodiment 2

[0035] On the basis of Embodiment 1, refer to Figure 2, Figure 6 , Figure 7 As shown, an intermittent rotating spoiler assembly 10 is provided on one side of the U-shaped plate 5. The intermittent rotating spoiler assembly 10 is used to intermittently disturb the water flow. The impact duration of the disturbed water flow is about 5 seconds, which can ensure that the water flow can fully impact various parts of the gas meter 2 and reduce the attachment of bubbles. The static interval is also about 5 seconds to ensure sufficient time to observe the bubbles. The intermittent rotating spoiler assembly 10 includes a mounting platform 101 fixed on one side of the U-shaped plate 5, and a turntable 102 is rotatably connected to one side of the mounting platform 101.

[0036] A convex groove 103 is provided inside the turntable 102. By providing the convex groove 103, the swing rod 104 can intermittently swing around the pin shaft, so that one side of the mounting platform 101 is connected to the swing rod 104 through the rotation of the pin shaft. A convex column 105 is fixed to one end of the swing rod 104. The convex column 105 extends to the inside of the convex groove 103 and slides inside the convex groove 103. Two limit blocks 106 are fixed to one side of the mounting platform 101. The limit blocks 106 are used to limit the movable plate 107 so that the movable plate 107 can move up and down.

[0037] A movable plate 107 is slidably connected between the opposite sides of the two limit blocks 106. A through slot 108 is penetrated on one side of the movable plate 107. A plug post 109 is fixed to the other end of the rocker arm 104. When the rocker arm 104 swings, it drives the plug post 109 to swing synchronously, and then the plug post 109 drives the movable plate 107 to move up and down. The through slot 108 reserves space for the movement of the plug post 109, and the plug post 109 extends to the inside of the through slot 108. The other end of the rocker arm 104 is rotatably connected to the limiting sleeve 1010 through a pin shaft. The limiting sleeve 1010 is used to limit the rack 2 1011 so that the rack 2 1011 can only move left and right in the limiting sleeve 1010.

[0038] One side of the turntable 102 is rotatably connected to a rack 2 1011 via a pin shaft, and the rack 2 1011 slides inside the limit sleeve 1010. One side of the mounting platform 101 is rotatably connected to a gear 2 1012 via a rotating shaft, and the gear 2 1012 meshes with the rack 2 1011. A block 1013 is fixed to one side of the movable plate 107, and the top of the block 1013 is engaged with the teeth of the gear 2 1012. The block 1013 can lock the gear 2 1012 to prevent the gear 1012 from rotating. A stirring rod 1014 is rotatably connected between the inner walls of the box body 1.

[0039] A paddle 1015 is fixed on the stirring rod 1014, one end of the stirring rod 1014 passes through the box 1 and extends to the outside of the box 1, a pulley 1016 is fixed on one end of the stirring rod 1014 and the rotating shaft of the gear 2 1012, and the two pulleys 1016 are connected by a belt 1017.

[0040] By setting up an intermittent rotating spoiler component 10, the rotation of the blade 1015 is used to disturb the water flow, so that the water flow periodically impacts the surface of the gas meter 2. During the intervals between the impacts of the water flow, the water around the gas meter 2 is relatively static, which is helpful for observing the bubbles; and when the water flow impacts the gas meter 2, the attachment time of the bubbles on the surface of the gas meter 2 can be shortened, preventing the bubbles from aggregating or merging due to long-term attachment, thereby making it easier to identify tiny, individual bubbles.

[0041] Pulley 2 11 is fixed on the output shaft of the motor 95 and the output shaft of the turntable 102. The two pulleys 11 are connected by belt 2 12. The swing mechanism 9 and the intermittent rotating spoiler assembly 10 are linked by setting the pulley 2 11 and the belt 2 12. By setting a motor 95, the two can work synchronously.

[0042] Embodiment 3

[0043] Based on Example 2, see Figure 4 and Figure 8 As shown, the box 1 is also provided with a water flow vibration component 13, which is used to vibrate the water flow, with a vibration frequency of 10 Hz and an amplitude of 5 mm. If the frequency is too low, it will not produce enough water body fluctuations to interfere with the attachment of bubbles and break the local static area. If the frequency is too high, the water body fluctuations will be too violent, resulting in a complex movement trajectory of the bubbles and difficulty in observation. The water flow vibration component 13 includes a cam 131 fixed on the stirring rod 1014, two side plates 132 are fixed on one side of the box 1, springs 133 are fixed on the tops of the two side plates 132, a top plate 134 is fixed between the tops of the two springs 133, the side surface of the cam 131 is in contact and compression with the bottom of the top plate 134, a vertical rod 135 is fixed on the top of the top plate 134, a connecting plate 136 is fixed on the top of the vertical rod 135, a vertical rod 137 is fixed on the bottom of the connecting plate 136, and a vibration plate 138 is fixed on the bottom of the vertical rod 137, and the vibration plate 138 can vibrate the water in the box 1.

[0044] By setting up a water flow vibration component 13, the vibration is transmitted to the water by utilizing the up and down vibration of the vibration plate 138, so that the water body around the gas meter 2 produces tiny fluctuations. Such fluctuations can further interfere with the attachment of bubbles to the surface of the gas meter 2, and can also continuously cause the bubbles to detach from the surface of the gas meter 2 during the intervals of water flow impact. In addition, the vibration helps to break up the local static areas that may be formed in the water body, making it easier for the bubbles to float to the water surface and be observed, thereby improving the comprehensiveness and accuracy of bubble detection.

[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0046] During operation, tighten the intake pipe 7 and the outlet pipe 8 on the intake port and the outlet port of the gas meter 2. Place the intake pipe 7 and the outlet pipe 8 on the U-shaped plate 5. Inject clear water into the box body 1. Start the cylinder 4. The cylinder 4 drives the gas meter 2 into the water. Introduce gas from the intake pipe 7 and discharge it from the outlet pipe 8. Observe whether there are bubbles generated in the water to judge the sealing performance of the gas meter 2. Start the motor 95. The motor 95 drives the disc 93 to rotate, thereby driving the tooth fork 97 to swing, and further driving the tooth rod 910 and the first rack 912 to reciprocate. The first rack 912 drives the first gear 913 to rotate forward and backward reciprocally, thereby driving the outlet pipe 8 and the gas meter 2 to swing reciprocally, so as to change the posture of the gas meter 2 to observe whether there are bubbles generated in each part of the gas meter 2. Drive the turntable 102 to rotate through the cooperation of the second pulley 11 and the second belt 12, thereby driving the swing rod 104 to swing, and at the same time driving the second rack 1011 to move left and right, and further driving the second gear 1012 to rotate intermittently. The swing rod 104 drives the moving plate 107 to move up and down. When the moving plate 107 moves upward, it drives the block 1013 to be stuck between two teeth of the second gear 1012 to prevent the second gear 1012 from rotating during the stop. The second gear 1012 synchronously drives the paddle 1015 to rotate and drives the water flow to stir. When using the intermittent rotation of the paddle 1015 to stir the water, the water flow will periodically impact the surface of the gas meter 2. During the intermittent period of the water flow impact, the water around the gas meter 2 is in a relatively static state, which helps to observe bubbles; when the water flow impacts the gas meter 2, it can shorten the adhesion time of bubbles on the surface of the gas meter 2, prevent bubbles from aggregating or fusing due to long-term adhesion, and is more likely to identify tiny and separate bubbles, improving the accuracy and resolution of bubble detection; at the same time, the stirring rod 1014 drives the cam 131 to rotate, and drives the vibrating plate 138 to vibrate up and down through the cooperation of the cam 131 and the spring 133. The vibration is transmitted to the water, causing tiny fluctuations in the water body around the gas meter 2. This kind of fluctuation can further interfere with the adhesion of bubbles on the surface of the gas meter 2, and can also continuously prompt bubbles to break away from the surface of the gas meter 2 during the intermittent period of the water flow impact. Moreover, the vibration helps to break the locally static areas that may form in the water body, making it easier for bubbles to float to the water surface to be observed, thereby improving the comprehensiveness and accuracy of bubble detection.

[0047] The above has described the embodiments of the invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
