Description

Technical Field

[0001] This utility model relates to the field of diaphragm gas meter technology, specifically to an external sampler for a diaphragm gas meter. Background Technology

[0002] Diaphragm gas meters work by deforming a diaphragm under the influence of gas flow, converting this deformation into rotational motion via a mechanical linkage. This motion drives a counter, and each reciprocating motion of the diaphragm releases a certain amount of gas. A roller on the counter rotates through a counting unit, thus measuring and displaying gas consumption. Current technology, particularly in remote areas or small exporting countries where local area networks are not yet available, still uses purely mechanical diaphragm gas meters, requiring on-site meter readings. Future development towards intelligent diaphragm gas meters would necessitate replacing the existing purely mechanical meters, increasing replacement costs and reducing efficiency. Therefore, this paper proposes an external sampler for diaphragm gas meters. Summary of the Invention

[0003] The purpose of this invention is to provide an external sampler for diaphragm gas meters in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an external sampler for a diaphragm gas meter, comprising a sampler housing, a counter installed inside the sampler housing, and a gear transmission assembly connected to the counter; characterized in that the sampler housing is provided with a reserved installation slot for easy later modification into an intelligent mode; a sensor for intelligent sampling of the counter's magnet is installed in the reserved installation slot.

[0005] Preferably, both the sensor and the sampler housing are provided with mounting holes to facilitate sensor installation.

[0006] Preferably, the sampler housing includes a bottom shell for mounting a gear transmission assembly and a top cover mounted on the bottom shell.

[0007] Preferably, the bottom shell is also fitted with a counter bracket for fixing the counter and a nameplate plate mounted on a fixed base.

[0008] Preferably, the bottom shell is symmetrically provided with mounting limit posts for limiting the installation of the counter bracket.

[0009] Preferably, the counter bracket has positioning through holes and limiting slots on both sides that are adapted to the installation limiting post.

[0010] Preferably, both the bottom shell and the top cover are provided with screw through holes for easy installation on a diaphragm gas meter.

[0011] The beneficial effects of this utility model are as follows: By setting a reserved installation slot on the sampler housing and installing the sensor in the reserved installation slot, the pure mechanical gas meter does not need to be completely replaced in the later modification. Only the sensor needs to be installed, thereby improving the convenience of the later modification and reducing the modification cost. Attached Figure Description

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the external sampler for a diaphragm gas meter according to this utility model.

[0017] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0018] See appendix Figure 1-3 As shown in the figure, this embodiment of an external sampler for a diaphragm gas meter includes a sampler housing 1, a counter 2 installed inside the sampler housing 1, and a gear transmission group 3 connected to the counter 2. The sampler housing 1 is characterized by a reserved mounting slot 101 for easy later conversion to an intelligent mode. A sensor 4 for intelligently sampling the counter 2's count is installed in the reserved mounting slot 101. By providing the reserved mounting slot 101 on the sampler housing 1 and installing the sensor 4 in the reserved mounting slot 101, purely mechanical gas meters do not require complete replacement during later modifications; only the sensor 4 needs to be installed, thereby improving the convenience of later modifications and reducing modification costs.

[0019] See appendix Figure 1As shown, both the sensor 4 and the sampler housing 1 are provided with fixing holes 401 to facilitate the installation of the sensor 4; the sensor 4 is fixed by passing bolts through the fixing holes 401 on the sensor 4 and the sampler housing 1, thereby facilitating the installation of the sensor 4.

[0020] See appendix Figure 2-3 As shown, the sampler housing 1 includes a bottom shell 102 for mounting the gear transmission assembly 3 and an upper cover 103 mounted on the bottom shell 102; the bottom shell 102 is also equipped with a counter bracket 104 for fixing the counter 2 and a nameplate plate 105 mounted on the counter bracket 104; the bottom shell 102 is symmetrically provided with mounting limiting posts 106 for limiting the mounting of the counter bracket 104; the counter bracket 104 is provided with positioning through holes 107 and limiting slots 108 on both sides, which are adapted to the mounting limiting posts 106; the bottom shell 102 and the upper cover 103 are both provided with screw through holes 109 for easy installation on a diaphragm gas meter; by installing the positioning through holes 107 and limiting slots 108 on the fixing seat 104 onto the mounting limiting posts 106 in the bottom shell 102, the counter bracket 104 is limited and installed in the bottom shell 102, thereby facilitating the installation of the counter 2 in the bottom shell 102.

[0021] When using this utility model, if a purely mechanical gas meter is later converted to an automatic reading meter, there is no need to replace the entire meter. Only the sensor 4 needs to be installed. The sensor 4 is fixed by bolts passing through the fixing holes 401 on the sampler housing 1. The sensor 4 is installed on the sampler housing 1 and uses the sensor 4 to sense the magnet inside the counter 2 to determine the value of the counter 2.

[0022] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
