Technical Field
[0001] This utility model relates to the field of gas meter technology, specifically to a wireless remote transmission diaphragm gas meter. Background Technology
[0002] In existing wireless remote-reading diaphragm gas meter applications, moisture-proof maintenance of the battery compartment has always been a critical aspect of ensuring stable operation of the gas meter. Traditional gas meters typically lack effective methods for monitoring the desiccant status, making it difficult for maintenance personnel to monitor the actual usage of the desiccant within the battery compartment in real time.
[0003] However, existing wireless remote-reading diaphragm gas meters have some drawbacks in practical use: During actual use, the humidity of the battery compartment environment changes constantly with seasonal and geographical factors. When the humidity is high, the desiccant continuously absorbs moisture, gradually reducing its drying capacity until it becomes ineffective. However, due to the lack of an automated alert mechanism, maintenance personnel can only periodically check the gas meter at fixed intervals to determine if the desiccant needs replacement. This periodic inspection method has significant drawbacks. On the one hand, if the inspection interval is set too long, the desiccant may have already expired, leading to increased humidity in the battery compartment, resulting in decreased battery performance, unstable communication, or even damage, severely affecting the normal operation of the gas meter. On the other hand, if the inspection interval is set too short, it increases the number of unnecessary manual inspections, consuming significant manpower and time costs, resulting in high maintenance costs. Furthermore, manual inspections are subject to subjectivity and uncertainty; negligence or lack of experience by inspectors may prevent timely detection of desiccant problems, thus failing to ensure the battery compartment remains in a dry environment.
[0004] To address these issues, we designed a wireless remote transmission diaphragm gas meter. Utility Model Content
[0005] The purpose of this invention is to provide a wireless remote transmission diaphragm gas meter to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the present invention provides a wireless remote transmission diaphragm gas meter, comprising a gas meter body and a battery compartment. The battery compartment is located inside the gas meter body, and a battery box is slidably disposed within the battery compartment. A moisture-proof box is fixedly connected to the bottom of the battery compartment, and a support plate is slidably connected to the inner side wall of the moisture-proof box. A drying box is slidably disposed on the top surface of the support plate. An opening for the drying box to pass through is provided on the side wall of the gas meter body, and a groove is provided on the bottom wall of the opening. A trigger block is slidably disposed within the groove and can slide vertically within the groove. The trigger block is elastically connected to the bottom wall of the groove, and a trigger switch is fixedly connected to the bottom wall of the groove. A warning light is fixedly connected to the outer side wall of the gas meter body.
[0007] Furthermore, a first spring is fixedly connected to the bottom surface of the trigger block, and the other end of the first spring is fixedly installed on the inner bottom wall of the groove.
[0008] Furthermore, a moving groove is provided through the support plate, a slider is slidably connected to the bottom wall of the moisture-proof box, one side wall of the top of the slider is set as an inclined surface, the moving groove is provided with an inclined surface that fits against the slider on the side near the slider, and a moving block is fixedly connected to the top surface of the slider, the moving block being located in the moving groove.
[0009] Furthermore, a second spring is fixedly connected to one side of the slider, and the other end of the second spring is fixedly installed on the inner side wall of the moisture-proof box. A third spring is fixedly connected to the bottom surface of the support plate, and the other end of the third spring is fixedly installed on the inner bottom wall of the moisture-proof box.
[0010] Furthermore, the outer wall of the moisture-proof box is rotatably connected to a movable plate via a spring hinge, and the movable plate can completely cover the opening.
[0011] Furthermore, two guide plates are fixedly connected to the top surface of the support plate. The two guide plates are symmetrically arranged, and the opposite side walls of the two guide plates are slidably connected to the drying box.
[0012] Furthermore, a locking cover is rotatably provided on the side wall of the battery box away from the battery compartment, and the battery box is connected to the gas meter body by the locking cover.
[0013] Furthermore, the trigger switch is electrically connected to the warning light.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the trigger block is pressed down along the inclined surface of the trigger block by the drying box. When the trigger block contacts the trigger switch, the warning light illuminates, indicating that the desiccant needs to be replaced. This design realizes the automated reminder function for desiccant replacement, eliminating the need for manual inspection of the desiccant and greatly saving maintenance costs and time. At the same time, timely replacement of the desiccant ensures that the battery compartment is always in a dry environment, further guaranteeing the normal operation of the gas meter.
[0015] 2. In this invention, by setting up a drying box to store the desiccant, the impact of environmental humidity on battery life is effectively avoided, ensuring the stability of the gas meter's main communication. When the battery compartment is damp, the desiccant can absorb moisture in time, and through gravity, it drives the support plate and slider to move, allowing the drying box to slide out automatically for desiccant replacement. This design not only improves the gas meter's adaptability to humid environments but also reduces the risk of communication interruption due to battery failure, significantly enhancing the overall stability and reliability of the equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-5 This utility model provides a technical solution: a wireless remote transmission diaphragm gas meter, including a gas meter body 1 and a battery compartment 2. The battery compartment 2 is located inside the gas meter body 1. A battery box 3 is slidably arranged inside the battery compartment 2. A moisture-proof box 4 is fixedly connected to the bottom of the battery compartment 2. A support plate 5 is slidably connected to the inner side wall of the moisture-proof box 4. A drying box 6 is slidably arranged on the top surface of the support plate 5. An opening 7 is opened on the side wall of the gas meter body 1 to accommodate the drying box 6. A groove 8 is opened on the bottom wall of the opening 7. A trigger block 9 is slidably arranged in the groove 8. The trigger block 9 can slide vertically in the groove 8. The trigger block 9 is elastically connected to the bottom wall of the groove 8. A trigger switch 10 is fixedly connected to the bottom wall of the groove 8. A warning light is fixedly connected to the outer side wall of the gas meter body 1. A first spring 11 is fixedly connected to the bottom surface of the trigger block 9. The other end of the first spring 11 is fixedly installed on the inner bottom wall of the groove 8. The trigger switch 10 is electrically connected to the warning light.
[0020] In practice, when the drying box 6 gradually slides into the opening 7, the drying box 6 presses down the trigger block 9 along the inclined surface set on the trigger block 9. The trigger block 9 is squeezed down by the drying box 6 and enters the groove 8. The first spring 11 is compressed. The trigger block 9 continues to descend until it contacts the trigger switch 10. At this time, the warning light electrically connected to the trigger switch 10 lights up, thereby indicating that the desiccant needs to be replaced.
[0021] See Figure 4 A movable groove 12 is provided through the bearing plate 5. A slider 13 is slidably connected to the bottom wall of the moisture box 4. One side wall of the top of the slider 13 is set as an inclined surface. The movable groove 12 is provided with an inclined surface that fits against the slider 13 on the side close to the slider 13. A movable block 14 is fixedly connected to the top surface of the slider 13. The movable block 14 is located in the movable groove 12.
[0022] The drying box 6 contains desiccant to prevent the battery life from being shortened by the humid environment and to ensure the stable communication of the gas meter body 1. When the battery compartment 2 is humid, the water vapor in the battery compartment 2 enters the dehumidification box 4. The desiccant in the drying box 6 absorbs the excess moisture, and its gravity will press the support plate 5 downward. Due to the inclined design of the support plate 5 and the slider 13, the slider 13 is driven to slide towards the opening 7. While the slider 13 is sliding, it drives the moving block 14 to push the drying box 6 out of the opening 7 to the outside of the dehumidification box 4, and then the desiccant is replaced.
[0023] See Figure 4 A second spring 15 is fixedly connected to one side of the slider 13, and the other end of the second spring 15 is fixedly installed on the inner wall of the moisture-proof box 4. A third spring 16 is fixedly connected to the bottom surface of the support plate 5, and the other end of the third spring 16 is fixedly installed on the inner bottom wall of the moisture-proof box 4. After the replacement is completed, the desiccant inside the drying box 6 is less than before because the newly replaced desiccant does not contain moisture. At this time, the second spring 15 will automatically reset and shorten, and pull the slider 13 with elastic force to drive the drying box 6 back into the battery compartment 2, while driving the support plate 5 to rise to the initial position.
[0024] See Figures 1-3 The outer wall of the moisture-proof box 4 is rotatably connected to a movable plate 17 via a spring hinge. The movable plate 17 can completely cover the opening 7. The movable plate 17 avoids the risk of the opening 7 being blocked by foreign objects due to normal exposure. Accidental pressing of the trigger block 9 may cause a false alarm. Two guide plates 18 are fixedly connected to the top surface of the support plate 5. The two guide plates 18 are symmetrically arranged. The opposite side wall of the two guide plates 18 is slidably connected to the drying box 6. The guide plates 18 can effectively guide the drying box 6 to move along a predetermined trajectory and prevent it from deviating from the predetermined path. A locking cover 19 is rotatably installed on the side wall of the battery box 3 away from the battery compartment 2. The battery box 3 is connected to the gas meter body 1 by a snap-fit through the locking cover 19.
[0025] Working principle: The drying box 6 contains desiccant to prevent the battery life from being shortened by the humid environment and to ensure the stable communication of the gas meter body 1. When the battery compartment 2 is humid, the moisture in the battery compartment 2 enters the dehumidification box 4. The desiccant in the drying box 6 absorbs excess moisture, and its gravity will press the support plate 5 downward. Due to the inclined design of the support plate 5 and the slider 13, the slider 13 is driven to slide towards the opening 7. At this time, the second spring 15 is stretched. While the slider 13 is sliding, it drives the moving block 14 to push the drying box 6 out of the opening 7 to the outside of the dehumidification box 4, and then the desiccant is replaced. After the replacement is completed, the drying box 6 has a reduced mass compared to the previous one because the newly replaced desiccant does not contain moisture. At this time, the second spring 15 will automatically return to its original position and shorten, and pull the slider 13 with elastic force, driving the drying box 6 back into the battery compartment 2, while driving the support plate 5 to rise to the initial position.
[0026] As the desiccant box 6 gradually slides into the opening 7, the desiccant box 6 presses down the trigger block 9 along the inclined surface on the trigger block 9. The trigger block 9 is squeezed downward by the desiccant box 6 and enters the groove 8. The first spring 11 is compressed. The trigger block 9 continues to descend until it contacts the trigger switch 10. At this time, the warning light electrically connected to the trigger switch 10 lights up, indicating that the desiccant needs to be replaced.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
