[0042] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to this application.

[0043] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0044] In one embodiment, a device for detecting a gas meter is described. Through the mutual cooperation of the rotating platform 2, the air blowing mechanism 3, and the air supply mechanism 4, the testing efficiency of the gas meter is greatly improved, the labor intensity of the staff is reduced, and the problems of time-consuming, laborious, and low efficiency of the current testing device are solved.

[0045] Specifically, referring to the accompanying drawings of the specification Figures 1 to 3 , a device for detecting a gas meter includes a bracket 1, a rotating platform 2, an air blowing mechanism 3, and an air supply mechanism 4. Among them, the rotating platform 2 is arranged on the bracket 1 and can rotate relative to the bracket 1. In addition, a number of mounting positions are arranged on the rotating platform 2, and the gas meters 5 to be detected are placed on the mounting positions. The number of mounting positions is arranged along the circumferential direction of the rotating platform 2, so that the number of gas meters 5 can rotate relative to the bracket 1.

[0046] Correspondingly, the air blowing mechanism 3 is arranged on the upper end surface of the bracket 1, and the air blowing mechanism 3 is provided with a number of air blowing ports 3123. The number of air blowing ports 3123 are respectively arranged in one-to-one correspondence with the mounting positions. When the gas meter 5 is installed on the mounting position, the air blowing port 3123 can be connected to the air inlet of the gas meter 5. The air supply mechanism 4 is communicated with the air blowing mechanism 3 to blow air to the number of air blowing ports 3123 of the air blowing mechanism 3 respectively, so as to realize the air ventilation test of the gas meter 5.

[0047] It can be understood that in the prior art, the testing of the gas meter 5 is mostly carried out by the staff holding the gas pipe by hand, connecting the gas pipe to the gas meter in turn, and completing the ventilation test of the gas meter one by one. This process has cumbersome steps and relatively high requirements for the staff, which results in a decrease in the testing efficiency and the testing effect. Especially in actual testing, after the ventilation test of the gas meter 5 is completed, other items need to be tested, such as the sealing test. This causes the staff to be unable to conduct the ventilation test on other gas meters during the sealing test, further reducing the work efficiency.

[0048] However, in a device for detecting a gas meter provided in this embodiment, the staff can place a plurality of gas meters 5 to be detected on the rotating platform 2 at one time, and then start the air supply mechanism 4. The air supply mechanism 4 conducts the ventilation test by supplying air to a group of several gas meters 5. After this group of several gas meters 5 are detected, the staff can rotate the rotating platform 2 to rotate this group of gas meters 5 to a suitable position, so that the staff can unload this group of gas meters 5 from the rotating platform 2, and then conduct the ventilation test on the next group of several gas meters 5. During the process of testing this group of gas meters 5, the staff can conduct the sealing test on the previous group of gas meters 5. In this way, the ventilation pre-operation and the sealing detection process of the gas meter 5 can be continuously carried out without interruption.

[0049] In addition, it should be noted that an installation groove is provided on the rotating platform 2, and the installation groove is matched with the gas meter 5 to form an installation position. During use, one end of the gas meter 5 is installed in the installation groove to ensure the stability of the gas meter 5 when it rotates with the rotating platform 2.

[0050] In one embodiment, referring to the accompanying drawings of the specification Figure 3 , this embodiment further describes the blowing mechanism 3. Among them, the blowing mechanism 3 includes a plurality of clamping components 31. The plurality of clamping components 31 are arranged on the bracket 1 along the circumferential direction of the rotating platform 2 and are respectively communicated with the air supply mechanism 4. Correspondingly, the blowing port 3123 is arranged on the clamping component 31. The clamping component 31 is used for clamping and cooperating with the gas meter 5, so that the blowing port 3123 is communicated with the air inlet of the gas meter 5.

[0051] In order to achieve the function of clamping and mating between the air blowing port 3123 and the air inlet of the gas meter, the clamping assembly 31 includes an installation pipe 311, a ventilation pipe 312, an installation seat 313, a support arm 314 and an elastic member 315. Among them, the installation pipe 311 is arranged on the bracket 1 and is communicated with the air supply mechanism 4. The ventilation pipe 312 includes a flexible pipe 3121 and a connecting pipe 3122. The connecting pipe 3122 is arranged at one end of the flexible pipe 3121. One end of the flexible pipe 3121 is arranged on the upper end surface of the installation pipe 311 and is communicated with the installation pipe 311. The air blowing port 3123 is arranged at the end of the connecting pipe 3122 far from the flexible pipe 3121 and is oriented towards the installation position, so that the gas generated by the air supply mechanism 4 can enter the gas meter 5 through the installation pipe 311, the flexible pipe 3121 and the connecting pipe 3122. Correspondingly, the installation seat 313 is arranged on the side of the installation pipe 311 close to the flexible pipe 3121. One end of the support arm 314 is hinged to the installation seat 313. The connecting pipe 3122 is inclined towards the direction close to the installation seat 313 through the flexible pipe 3121 and is fixedly connected to the other end of the support arm 314. Correspondingly, the elastic member 315 is arranged between the installation seat 313 and the connecting pipe 3122. Since the flexible pipe 3121 can be deformed, the staff can make the air blowing port 3123 move away from or close to the gas meter 5 by rotating the connecting pipe 3122.

[0052] Generally speaking, the elastic member 315 is set as a spring. During use, the staff rotates the connecting pipe 3122 to make the air blowing port 3123 rotate away from the rotating platform 2. The flexible pipe 3121 is deformed and the elastic member 315 is compressed. The gas meter 5 is installed in the installation position. Then the staff releases the connecting pipe 3122, so that the air blowing port 3123 is clamped and mated with the air inlet of the gas meter 5 under the restoring force of the elastic member 315, thereby realizing the connection and communication between the air blowing mechanism 3 and the gas meter 5.

[0053] Preferably, a sealing ring is arranged in the air blowing port 3123 to improve the sealing performance between the air blowing port 3123 and the air inlet of the gas meter 5 and ensure the accuracy during the detection of the gas meter 5.

[0054] In one embodiment, refer to the accompanying drawings of the specification Figures 1 to 3, this embodiment further describes the bracket 1. The bracket 1 includes a base 11 and a support member 12. The rotating platform 2 is rotatably arranged on the support member 12 with the central axis of the support member 12 as the rotation axis. The installation position is arranged on the upper end surface of the rotating platform 2 to drive the gas meter 5 to rotate. Correspondingly, the support member 12 is vertically arranged on the upper end surface of the base 11, that is, the base 11 is arranged at one end of the support member 12 and is located on the side of the rotating platform 2 away from the installation position. The air supply mechanism 4 is arranged on the base 11. An air flow channel communicating with the air blowing port 3123 and the air supply mechanism 4 is arranged in the support member 12, so that the gas generated by the air supply mechanism 4 enters the gas meter 5 through the air flow channel, the installation pipe 311, the flexible pipe 3121 and the connecting pipe 3122.

[0055] Generally speaking, the air supply mechanism 4 includes a vacuum pump 41 and an air inlet pipe 42. The vacuum pump 41 is arranged on the base 11 and is communicated with the air flow channel through the air inlet pipe 42. Of course, in actual production applications, there are various structures of the air supply mechanism 4, which will not be described one by one here, and all are within the protection scope of the present utility model.

[0056] Furthermore, a through hole 21 matching the support member 12 is formed on the rotating platform 2. One end of the support member 12 of the bracket 1 passes through the through hole 21 to rotatably sleeved the rotating platform 2 on the outside of the support member 12. In addition, a limiting portion 121 arranged along the circumferential direction of the support member is arranged on the support member 12. The rotating platform 2 is located on the side of the limiting portion 121 away from the base, so that the rotating platform 2 will not slide off the support member 12 under the limiting action of the limiting portion 121, ensuring that the rotating platform 2 can rotate stably and reliably on the support member 12.

[0057] Preferably, the device for gas meter detection further includes a bearing. The bearing is rotatably sleeved on the outside of the support member 12 and is arranged between the rotating platform 2 and the support member 12. Correspondingly, openings communicating with a plurality of air flow channels are arranged on the support member 12. The openings are arranged in one-to-one correspondence with the clamping assemblies. The air supply mechanism 4 is used to blow air through the openings to the air blowing ports 3123 respectively. Specifically, the air supply mechanism 4 blows air to the air inlet of the gas meter 5 through the air flow channel, the opening, the installation pipe 311 and the air blowing port 3123 respectively.

[0058] Furthermore, the air supply mechanism 4 further includes a vacuum valve. The vacuum valve is used to control the blowing of a plurality of air blowing ports 3123 respectively, that is, the staff can control the corresponding air blowing ports 3123 to blow air to the gas meter 5 through the vacuum valve.

[0059] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
