Description

Technical Field

[0001] This utility model relates to the field of water meter technology, and in particular to a universal Internet of Things (IoT) water meter. Background Technology

[0002] With the increasing sophistication of water resource management, traditional mechanical water meters are no longer sufficient to meet the needs of modern water systems. In recent years, the application of IoT technology in the water meter field has gradually become widespread. A search reveals a Chinese patent with authorization number CN222866001U, which discloses an IoT water meter with convenient battery replacement. This invention relates to the field of IoT water meter technology, including an IoT water meter. The top of one rear side of the IoT water meter is fixedly connected to a water inlet pipe, and the bottom of one rear side of the IoT water meter is fixedly connected to a water outlet pipe. A battery compartment is located on the lower part of the other rear side of the IoT water meter. A battery cover assembly is located at the rear of the battery compartment. Sliding grooves are respectively formed on the left and right sides of the rear of the IoT water meter near the battery compartment. A locking component is located on the lower side of the rear of the IoT water meter near the battery compartment, and a positioning component is located on the upper side of the rear of the IoT water meter near the two sliding grooves. This invention allows manual upward pushing of the battery cover assembly to expose the battery compartment. The positioning component magnetically positions the battery cover assembly, allowing battery replacement within the battery compartment. The battery cover assembly is then moved downwards and fixed to the locking component, facilitating easy opening of the battery cover assembly.

[0003] The aforementioned patent for an IoT water meter that facilitates battery replacement has the following drawbacks: This water meter lifts the battery cover assembly upwards along the track of the slide, eliminating the need to remove the battery cover assembly from the IoT water meter. This solves the problem of reduced battery installation efficiency caused by the need to remove and reinstall the battery cover during battery replacement. However, the lack of a sealing structure between the battery cover and the battery compartment means that the battery is easily damaged by moisture when the water meter is installed in a humid environment, reducing its lifespan. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a universal Internet of Things (IoT) water meter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A universal IoT water meter includes an IoT water meter body. L-shaped fixing plates are fixedly connected to the top of both sides of the IoT water meter body. Each L-shaped fixing plate has irregularly shaped holes, including horizontal holes and arc-shaped holes. The bottom of the arc-shaped hole is connected to one end of the horizontal hole. Two sliders are slidably connected in each irregularly shaped hole. A common rotating rod is fixedly connected to the outer side of the two sliders on the same side. A common horizontal bar is fixedly connected to one end of the two rotating rods. A battery compartment baffle is fixedly connected to the side of the horizontal bar closest to the IoT water meter body. A protruding rod is fixedly connected to the outer end of each rotating rod away from the horizontal bar.

[0007] Preferably, the IoT water meter body has a battery compartment at the top of one end near the battery compartment baffle, and a slot is provided at the outer end of the battery compartment. A rubber pad is fixedly connected to the slot. The compression deformation of the rubber pad prevents moisture from entering the battery compartment. The slot is compatible with the battery compartment baffle. A storage battery is fixedly connected inside the battery compartment. A support plate is fixedly connected to the bottom of the side of the IoT water meter body near the battery compartment.

[0008] Preferably, the two L-shaped fixing plates are rotatably connected to the same arc-shaped plate on their outer sides, and the top of both ends of the arc-shaped plate are provided with sliding grooves.

[0009] Preferably, each of the protruding rods is slidably connected in adjacent grooves.

[0010] Preferably, a sliding sleeve is fixedly fitted in the middle of the arc-shaped plate, a pull rod is slidably fitted inside the sliding sleeve, and a retaining ring is fixedly connected to the middle of one side of the pull rod inside the arc-shaped plate. A spring is fitted between the retaining ring and the sliding sleeve, and a pull ring is fixedly connected to the pull rod on the outside of the arc-shaped plate. The arrangement of the pull rod, retaining ring and spring facilitates locking of the arc-shaped plate, so that the battery compartment of the IoT water meter body will not get damp when in use.

[0011] Preferably, a fixing sleeve is fixedly connected to the middle of the side of the IoT water meter body near the arc plate, and the fixing sleeve is compatible with the pull rod.

[0012] Preferably, an inlet pipe is fixedly connected to one end of the IoT water meter body near the fixed sleeve, and a drain pipe is fixedly connected to the other end of the IoT water meter body.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing technologies such as a battery compartment, rubber pad, battery compartment baffle, irregularly shaped hole slider, and arc-shaped plate, the upward rotation of the arc-shaped plate causes the battery compartment baffle to automatically disengage from the battery compartment and rotate upward, facilitating battery replacement. When the arc-shaped plate rotates downward, the battery compartment baffle descends and compresses the rubber pad, causing the rubber pad to deform and protect the battery from moisture. This effectively solves the problem of easily damaged batteries in IoT water meters in humid environments, as mentioned in the background technology. Furthermore, it enables quick battery replacement without complex operations, reducing maintenance difficulty and time costs, minimizing water meter downtime due to battery failure, enhancing the adaptability and durability of IoT water meters in complex environments, and reducing overall maintenance frequency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A universal IoT water meter includes an IoT water meter body 1. L-shaped fixing plates 7 are fixedly connected to the top of both sides of the IoT water meter body 1. Each of the two L-shaped fixing plates 7 has an irregularly shaped hole 701, including a horizontal hole and an arc-shaped hole. The bottom of the arc-shaped hole is connected to one end of the horizontal hole. Two sliders 803 are slidably connected in each irregularly shaped hole 701. A common rotating rod 8 is fixedly connected to the outer side of the two sliders 803 on the same side. One end of the two rotating rods 8 is fixedly connected to a common horizontal rod 801. A battery compartment baffle 802 is fixedly connected to the side of the horizontal rod 801 closest to the IoT water meter body 1. A protruding rod 804 is fixedly connected to the outer end of the two rotating rods 8 away from the horizontal rod 801. The two sliders 803 slide in the irregularly shaped holes 701, allowing the rotating rods 8 to move horizontally to the arc-shaped hole of the irregularly shaped hole 701 and to rotate at a certain angle.

[0024] In this utility model, a battery compartment 5 is provided at the top of one end of the IoT water meter body 1 near the battery compartment baffle 802, and a slot is provided at the outer end of the battery compartment 5. A rubber pad 501 is fixedly connected to the slot. The deformation of the rubber pad 501 improves the waterproofness inside the battery compartment 5. The slot is adapted to the battery compartment baffle 802. A storage battery 6 is fixedly connected inside the battery compartment 5. A support plate 4 is fixedly connected to the bottom of the side of the IoT water meter body 1 near the battery compartment 5. The support plate 4 can facilitate the alignment and positioning of the battery compartment baffle 802 when it is engaged with the rubber pad 501.

[0025] In this utility model, the two L-shaped fixing plates 7 are rotatably connected to the same arc plate 9 on their outer sides. Both ends of the arc plate 9 are provided with sliding grooves 901.

[0026] In this invention, each of the protruding rods 804 is slidably connected in adjacent sliding grooves 901. By rotating the arc plate 9, the sliding groove 901 moves with the protruding rod 804, thereby realizing the horizontal movement and rotation of the rotating rod 8.

[0027] In this utility model, a sliding sleeve 902 is fixedly sleeved in the middle of the arc plate 9, and a pull rod 903 is slidably sleeved inside the sliding sleeve 902. A retaining ring 904 is fixedly connected to the middle of one side of the pull rod 903 inside the arc plate 9. A spring 905 is sleeved between the retaining ring 904 and the sliding sleeve 902. A pull ring is fixedly connected to the outside of the pull rod 903.

[0028] In this utility model, a fixing sleeve 101 is fixedly connected to the middle of the side of the IoT water meter body 1 near the arc plate 9, and the fixing sleeve 101 is adapted to the pull rod 903. Through the cooperation of the fixing sleeve 101 and the pull rod 903, the arc plate 9 will not move or loosen when it is fixed, so that the battery compartment baffle 802 will not leave the battery compartment 5.

[0029] In this utility model, the end of the IoT water meter body 1 near the fixed sleeve 101 is fixedly connected to the water inlet pipe 2, and the other end of the IoT water meter body 1 is fixedly connected to the drain pipe 3.

[0030] Working Principle: When in use, the IoT water meter body 1 is installed in the pipeline through the threads on the inlet pipe 2 and the outlet pipe 3. After the battery 6 is installed, it can work normally, monitor water consumption, record water data, and remotely pay water bills. When the battery 6 is low on power after prolonged use, the user can pull the lever 903 to compress the spring 905. At this time, the lever 903 separates from the fixed sleeve 101, and the arc plate 9 can rotate. Rotating the arc plate 9 upwards by a certain angle, the protrusion 804 of the rotating rod 8 slides in the groove 901. When the groove 901 rotates with the arc plate 9, since the two sliders 803 initially slide in the horizontal hole of the irregular hole 701, when the groove 901 rotates, it will push the two rotating rods 8 to move the battery compartment baffle 802 horizontally, causing the battery compartment baffle 802 to leave the rubber pad 501. When one slider 803 moves to the irregular hole 701... When the arc-shaped plate 9 continues to rotate, the sliding groove 901 drives the protruding rod 804 to slide, preventing the rotating rod 8 from moving horizontally. At this time, the slider 803 near the arc-shaped hole 701 can only slide into the arc-shaped hole. Then, the rotating rod 8, along with the crossbar 801 and the battery compartment baffle 802, rotates upward, exposing the battery 6. The user can then replace the battery 6. After the replacement, the arc-shaped plate 9 resets, driving the rotating rod 8 and the battery compartment baffle 802 back to the horizontal position. When the slider 803 disengages from the arc-shaped hole 701, the battery compartment baffle 802 presses against the rubber pad 501, causing the rubber pad 501 to deform and achieve waterproofing. This prevents the battery 6 from being damaged by moisture in a humid environment during the operation of the IoT water meter body 1, extending the service life of the battery 6. At the same time, all components of the IoT water meter body 1 are treated with anti-rust treatment and will not rust.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
