Description

Technical Field

[0001] This utility model relates to the technical field of gas meter protective covers, specifically a protective cover structure for a gas meter housing with wireless communication function. Background Technology

[0002] With the promotion of intelligent gas metering systems, gas meters with wireless communication capabilities are gradually replacing traditional mechanical gas meters. These meters transmit real-time gas consumption data to a remote management platform via a wireless transmission module, enabling automatic meter reading and gas consumption monitoring. However, communication gas meters are often installed on building exteriors or in outdoor environments, where they are exposed to sunlight, rain, and temperature fluctuations for extended periods. This exposure can easily lead to problems such as casing aging, water ingress, corrosion, or signal attenuation. Therefore, protective covers are typically required to ensure long-term stable operation. Communication gas meters mainly consist of a metering mechanism, an electronic control unit, a power supply system, a wireless communication module, and a protective casing structure. When gas flows through the metering mechanism, it drives the diaphragm or rotor, which is then transmitted to the encoder via magnetic coupling, generating an electrical pulse signal proportional to the flow rate. The electronic control unit collects, calculates, and stores the signal. The wireless communication module then encrypts the data and transmits it externally via an antenna, enabling remote meter reading and monitoring. Simultaneously, the power supply system provides continuous low-power energy support, while the protective casing structure protects internal components from external environmental influences, thus achieving coordinated operation of metering, communication, and protection.

[0003] In existing technologies, once the gas meter body is installed in the wall, adding or replacing the protective cover requires disassembling the entire gas meter, which is inconvenient and sometimes even requires disassembling the gas meter body again, making the work cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a protective cover structure for a gas meter housing with wireless communication function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a protective shell, which is fitted over the outside of the main body of the communication gas meter. A back plate is installed on the back of the protective shell, and the back plate is fixed to the wall by connecting ears. Hinges are installed on both sides of the protective shell by screws, and a connecting plate is installed on the other side of the hinges. The back plate and the connecting plate are fixed together by a connecting structure.

[0006] Preferably, the hinges are provided in four sets, the four sets of hinges are symmetrical about the center of the protective shell, and all four sets of hinges are located on the side of the protective shell.

[0007] Preferably, the connecting plate is provided in multiple sets, and the connecting plate corresponds one-to-one with the hinge. When the back plate is not installed, the back of the connecting plate is attached to the wall, and the connecting plate is installed on the wall by screws.

[0008] Preferably, the connecting structure includes side plates, pressure plates, slots, and clips. Two sets of side plates are fixed to the side surface of the rear plate. Two sets of pressure plates are fixed to the lower surface of the side plates, with each pressure plate corresponding to one of the side plates. Slots are located on the back of the connecting plate. Two sets of clips are fixed to both sides of the rear plate, and the clips slide within the slots. When the rear plate is installed on the back of the protective shell, the surface of the connecting plate is in contact with the pressure plates, and the back of the connecting plate is in contact with the side of the rear plate. A through hole is provided on the surface of the pressure plate, penetrating both the pressure plate and the connecting plate, and extending to the side of the rear plate. The through hole connects the pressure plate and the connecting plate using screws. The slots and clips are located in front of the through holes.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The protective cover structure for a gas meter housing with wireless communication function proposed in this utility model first installs the protective cover on the wall, and then installs the main body of the communication gas meter on the back plate. If the main body of the communication gas meter has been previously installed, simply loosen the screws between the pressure plate and the connecting plate, then pull out the back plate. The retaining strip on the side of the back plate slides upward along the retaining groove, and the connecting plate is released from the restraint between the pressure plate and the back plate. The connecting plate rotates along the hinge until the back of the connecting plate is flush with the wall. The connecting plate is then installed on the wall with bolts. This not only allows for the re-installation of the protective cover on the outside of the communication gas meter body later, avoiding the need to disassemble the communication gas meter body again and reducing trouble, but also allows the protective cover to be installed on the wall as a whole while installing the communication gas meter body, and then the communication gas meter body to be installed inside the protective cover.

[0012] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a protective cover structure for a gas meter housing with wireless communication function, including a protective shell 1, the protective shell 1 being fitted on the outside of the main body 2 of the communication gas meter, a back plate 3 being installed on the back of the protective shell 1, and the back plate 3 being fixed to the wall by connecting ears. Specifically, the main body 2 of the communication gas meter is organically integrated with upper and lower shells and a transparent reading window, a battery compartment and power supply system, a metering mechanism and pulse / volume acquisition unit, electronic control and local storage, a wireless communication module and antenna and its radio frequency channel, a sealing and heat dissipation structure, and mounting fasteners. The metering mechanism converts instantaneous flow or volume information into pulse or digital signals, which are then collected, temporarily stored, and encrypted by the electronic control unit. The signal is then reported to the external gateway / cloud via the wireless communication module through the antenna and a dedicated radio frequency channel. At the same time, the power supply system and low-power strategy ensure long-term operation. The sealing and heat dissipation design of the shell protects the internal components from environmental corrosion through the flow guide, heat conduction sheet, and rainproof structure, while also working in conjunction with the radio frequency transparent / waveguide channel and local shielding to balance signal penetration and anti-interference.

[0014] To reiterate, the metering mechanism uses the ZENNER Atmos G1.6 / 2.5 model, and the wireless communication module uses the Landis+Gyr M125 RF model. The diaphragm-type metering mechanism causes the diaphragm to deform alternately when gas flows in, driving gears and magnetic coupling for mechanical counting. At the same time, the metering value is converted into an electrical signal or pulse output through the encoding mechanism. After the output data is transmitted to the microprocessor built into the wireless communication module, the encrypted metering data is periodically sent to the aggregation gateway through its radio frequency transmitter based on RF Mesh network technology, enabling remote data reading without the need for manual meter reading.

[0015] Example 2 Based on Embodiment 1, in order to enable the installation of protective covers according to different environments, it is proposed that hinges 4 be installed on both sides of the protective shell 1 by screws. There are four sets of hinges 4, which are symmetrical about the center of the protective shell 1 and are all located on the side of the protective shell 1. Connecting plates 5 are installed on the other side of the hinges 4. There are multiple sets of connecting plates 5, and each connecting plate 5 corresponds to a hinge 4. When the back plate 3 is not installed, the back of the connecting plate 5 is attached to the wall and is installed on the wall by screws. The back plate 3 and the connecting plate 5 are fixed by a connecting structure, which includes side plates 6, pressure plates 7, slots 8 and clips 9. There are two sets of side plates 6, and both sets of side plates 6 are fixed. On the side surface of the rear plate 3, there are two sets of pressure plates 7. Both sets of pressure plates 7 are fixed to the lower surface of the side plate 6. The pressure plates 7 and the side plates 6 correspond one-to-one. The slot 8 is opened on the back of the connecting plate 5. There are two sets of clips 9. The two sets of clips 9 are fixed on both sides of the rear plate 3. The clips 9 slide in the slot 8. When the rear plate 3 is installed on the back of the protective shell 1, the surface of the connecting plate 5 is in contact with the pressure plate 7, and the back of the connecting plate 5 is in contact with the side of the rear plate 3. The surface of the pressure plate 7 is provided with a through hole 10. The through hole 10 passes through the pressure plate 7 and the connecting plate 5. The through hole 10 passes through to the side of the rear plate 3. The through hole 10 connects the pressure plate 7 and the connecting plate 5 by screws. The slot 8 and the clip 9 are both located in front of the through hole 10. Specifically, if the gas meter body has already been installed, simply loosen the screws between the pressure plate 7 and the connecting plate 5, then pull the back plate 3 upwards, allowing the retaining strips 9 on both sides of the back plate 3 to slide along the grooves 8, thereby releasing the fixing constraint between the connecting plate 5 and the pressure plate 7 and the back plate 3. At this time, the connecting plate 5 rotates under the action of the hinge 4, causing its back to fit tightly against the wall. Then, the connecting plate 5 is directly fixed to the wall with bolts, achieving stable installation of the protective shell 1 and the wall. The protective shell 1 is thus fixed. Continue to protect the main body 2 of the gas meter; when facing the gas meter body that is not installed, when the gas meter body is installed together with the protective cover, simply rotate the connecting plate 5 around the hinge 4 until the surface of the connecting plate 5 is flush with the side of the protective shell 1, and then press the back plate 3 down from above. At this time, the locking strips 9 on both sides of the back plate 3 are aligned with the locking grooves 8 on the back of the connecting plate 5. When the lower surface of the side plates 6 on both sides of the back plate 3 is in contact with the upper surface of the connecting plate 5, the pressure plate 7 presses down on the connecting plate 5, fixing the connecting plate 5 and achieving a stable lock.

[0016] In use, when encountering a gas meter body that has already been installed, simply loosen the screws between the pressure plate 7 and the connecting plate 5, then pull the back plate 3 upwards. This allows the retaining strips 9 on both sides of the back plate 3 to slide off along the slots 8. At this time, the connecting plate 5 rotates under the action of the hinge 4, its back side adhering to the wall and directly fixed with bolts, thus achieving a stable connection between the protective shell 1 and the wall. The protective shell 1 continues to provide external protection for the gas meter body 2, allowing for replacement or reinstallation of the protective cover without disassembling the gas meter body. When encountering a situation where the gas meter body has not yet been installed, simply rotate the connecting plate 5 around the hinge 4 until it is flush with the side of the protective shell 1, then press the back plate 3 down from above, aligning the retaining strips 9 on both sides of the back plate 3 with the slots 8 on the back of the connecting plate 5 and sliding them in. When the lower surface of the side plate 6 of the back plate 3 adheres to the upper surface of the connecting plate 5, the pressure plate 7 applies pressure to the connecting plate 5, completing the fixing and locking.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
