Description

Technical Field

[0001] This utility model relates to the field of smart water meter technology, and in particular to a smart water meter with a split controller. Background Technology

[0002] A smart water meter is a new type of water meter that uses modern microelectronics, sensing, communication, and intelligent control technologies to measure water consumption, transmit water data, and settle transactions. As an important component of modern water supply management, smart water meters are widely used in residential, commercial, and industrial areas. Traditional smart water meters typically adopt an integrated design, combining the water meter and controller into a single housing. With technological advancements, split-type smart water meters have gradually emerged, separating the water meter and controller for flexible installation and maintenance. The split design allows the controller to be installed independently of the water meter, thus adapting to different environmental needs.

[0003] A search revealed Chinese Patent Publication No. CN203772347U, which discloses a split-structure smart water meter, belonging to the field of water meter manufacturing technology. This utility model, without altering the overall structural dimensions of the water meter or affecting the layout and installation of the controller, changes the original integrated structure of the smart water meter base and electronic control valve. It adopts a split structure for the base meter shell and the electronic control valve body, assembled as a single unit using a mechanical connection. Because the base meter shell and electronic control valve body are cast separately, the casting process difficulty is greatly reduced, the pass rate of the base meter shell blank is significantly increased, and the prerequisite for reducing the wall thickness of the base meter shell blank is provided. This significantly improves production efficiency, significantly reduces production costs and maintenance expenses, and saves materials and energy, demonstrating significant advantages. While there are economic and social benefits, currently, the fixing methods for split-type smart water meter controllers include the following: First, fixing the controller to a bracket near the water meter with bolts; second, using a snap-on design, fixing the controller to the mounting plate with plastic clips; and third, using magnetic fixing, which uses magnetic materials to attract the controller. Although bolt fixing is secure, it requires tools and is time-consuming to disassemble; snap-on design is easy to disassemble, but the clips are prone to aging and breakage after long-term use; magnetic fixing is convenient to disassemble, but it is susceptible to interference from external magnetic fields and has poor stability. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a smart water meter with a split controller, aiming to improve the problems of difficult disassembly and insufficient stability of existing split smart water meter controllers, which lead to high maintenance costs, low efficiency, and seriously affect the normal operation of water supply management.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smart water meter with a split controller, comprising a meter body, a separation mechanism fixedly connected to the right side of the outer wall of the meter body, the separation mechanism being used for quick separation and disassembly, and multiple clamping mechanisms slidably connected at equal distances to the upper and lower ends of the meter body, the clamping mechanisms being used for clamping and fixing; the separation mechanism includes a mounting plate, the mounting plate being installed on the right side of the outer wall of the meter body, a bolt threadedly connected to the middle of the inner wall of the mounting plate, a grooved hollow block fixedly connected to the bottom of the mounting plate, a grooved short block slidably connected to the inner wall of the grooved hollow block, a control box fixedly connected to the front side of the outer wall of the grooved short block, and a locking mechanism fixedly connected to the right side of the outer wall of the grooved hollow block.

[0006] The above technical solution involves fixing the mounting plate to the meter body with bolts, using the hollow block at its bottom groove as the mounting base for the control box. The short block of the control box slides into the hollow block to complete the pre-fixation. The locking mechanism on the right side of the hollow block engages to lock after the short block is in place, achieving a stable connection. By operating the locking mechanism to release the restriction, the control box can be separated from the meter body by sliding out the short block, facilitating maintenance.

[0007] As a further description of the above technical solution: The locking mechanism includes a U-shaped piece, which is fixedly connected to the right side of the outer wall of the hollow block in the groove. A locking post is slidably connected to the middle of the inner wall of the U-shaped piece, and a compression spring is installed on the outer wall of the locking post.

[0008] The above technical solution involves: a U-shaped piece fixed to the right side of the hollow block in the groove, providing a sliding track for the locking post; the locking post, fitted with a compression spring, slides inside the U-shaped piece. Initially, the spring pushes the locking post close to the hollow block in the groove. When the short block in the groove slides into the hollow block, it pushes the locking post and compresses the spring. After the locking grooves are aligned, the spring pushes the locking post into the locking groove of the short block in the groove, completing the locking. Pulling the locking post away from the hollow block in the groove compresses the spring and disengages the locking post from the locking groove, allowing it to slide out of the short block in the groove.

[0009] As a further description of the above technical solution: The clamping mechanism includes multiple movable plates, which are equidistantly slidably connected to the upper and lower ends of the outer wall of the watch body. An arc-shaped plate is fixedly connected to the right side of the outer wall of each movable plate. Multiple spring pads are fixedly connected to adjacent sides of the outer wall of the arc-shaped plate at equal intervals. Adjustment components are fixedly connected to the upper and lower ends of the outer wall of the watch body.

[0010] The above technical solution works as follows: When the watch body needs to be fixed, the adjusting component causes the moving plate to move the arc plate closer to each other. The spring pads on the arc plate come into contact with the installation environment and are squeezed. The elastic deformation of the spring pads forms a clamping force, which helps to fix the watch body. When the watch body needs to be adjusted or disassembled, the adjusting component drives the moving plate in the opposite direction, so that the arc plates move away from each other. The clamping force of the spring pads is released, making it easier to operate.

[0011] As a further description of the above technical solution: The adjustment assembly includes multiple clamps, which are equidistantly fixedly connected to the lower end of the outer wall of the watch body. An L-shaped plate is fixedly connected to the left side of the outer wall of each clamp. A two-way lead screw is rotatably connected to the middle of the inner wall of the L-shaped plate. A guide post passes through the upper middle part of the inner wall of the L-shaped plate.

[0012] The above technical solution involves a bidirectional lead screw on the L-shaped plate with reverse threads. When rotating, the screw drives the two moving plates to move closer or further away synchronously, thus achieving clamping / release. The guide post is parallel to the bidirectional lead screw, and the moving plates are slidably connected to it, limiting the rotational offset of the moving plates and ensuring smooth sliding.

[0013] As a further description of the above technical solution: The inner wall of the movable piece is threadedly connected to the outer wall of the bidirectional lead screw, and the inner wall of the movable piece is slidably connected to the outer wall of the guide post.

[0014] The above technical solution works as follows: when the bidirectional lead screw rotates, it drives the moving plate to move along the lead screw axis. At the same time, the inner wall of the moving plate is slidably connected to the outer wall of the guide column. The guide column restricts the tendency of the moving plate to rotate with the lead screw, ensuring that the moving plate slides smoothly only in a straight line, avoiding deviation and ensuring adjustment accuracy.

[0015] As a further description of the above technical solution: A mounting plate is fixedly connected to the rear side of the outer wall of the watch body, and two bolts are threadedly connected to the outer wall of the mounting plate near the four corners.

[0016] The above technical solution involves fixing a mounting plate to the rear side of the outer wall of the meter body. The mounting plate serves as the mounting position for the meter body, which improves installation stability and facilitates installation.

[0017] As a further description of the above technical solution: The outer right side of the mounting plate is threaded with bolt three, and the outer wall of bolt three is threaded with a label.

[0018] The above technical solution involves first aligning the holes on the label with the threaded holes on the right side of the mounting plate, then passing bolt three through the holes on the label and screwing it into the threaded holes on the mounting plate. As bolt three is tightened, its head presses against the surface of the label. The engagement between bolt three and the threads of the mounting plate generates a tightening force, firmly fixing the label to the right side of the outer wall of the mounting plate, thus preventing the label from shifting or falling off.

[0019] As a further description of the above technical solution: The locking pin engages with the short block in the groove, and the outer wall of the locking pin is slidably connected to the inner wall of the hollow block in the groove.

[0020] The above technical solution allows for the following: When the control box needs to be disassembled, the locking pin is pulled away from the hollow block in the groove. At this time, the outer wall of the locking pin slides along the inner wall of the hollow block in the groove, gradually disengaging from the locking groove of the short block in the groove. After the locking pin is completely removed from the locking groove, the sliding restriction of the short block in the groove is released, and it can slide out along the inner wall of the hollow block in the groove, thus achieving the separation of the control box from the meter body.

[0021] This utility model has the following beneficial effects: 1. In this utility model, during installation, the short groove block is aligned with the hollow groove block and slid in to initially position the control box. In the locking mechanism on the right side of the hollow groove block, the locking pin on the U-shaped piece is fitted with a compression spring. When the short groove block is fully slid in, the spring releases its elastic force to push the locking pin through the hollow groove block and engage with the short groove block, thus locking and fixing the control box. During disassembly, the locking pin is pulled to slide along the U-shaped piece and compress the spring. After the locking pin disengages from the short groove block and the hollow groove block, the short groove block can be slid out, achieving rapid separation of the control box from the meter body and improving maintenance efficiency.

[0022] 2. In this utility model, the clamp is fixed to the meter body, the L-shaped plate supports the bidirectional lead screw and guide column, the moving plate is threaded to the lead screw and slidably connected to the guide column, rotating the lead screw can drive the moving plate to move smoothly, and then drive the arc plate to move. When the lead screw is rotated in the forward direction, the arc plate moves closer and a clamping force is generated by the inner spring pad; rotating in the reverse direction releases the clamping force, which is convenient for adjustment or disassembly. The bidirectional lead screw can achieve precise adjustment to adapt to different diameter installation foundations; the spring pad enhances stability, avoids rigid damage and buffers vibration, and ensures measurement accuracy.

A control box 203 is fixedly connected to the front side of the outer wall of the short groove block 204. The model of the control box 203 is LXLN-50. The basic working principle and its components are as follows: the water meter controller consists of a metering module (such as a pulse water meter, ultrasonic transmitter, etc.). The device consists of a metering module, a control module, a communication module, an execution module (electric valve), and a power supply module. Its working principle is to collect water flow data through the metering module, process and store it through the control module, upload or receive remote commands through the communication module, and then control the valve opening and closing through the execution module. At the same time, the power supply module supplies power to each component, thereby completing the functions of water metering, remote monitoring and valve control.

A compression spring 2062 is sleeved on the outer wall of the locking pin 2063. When the grooved short block 204 is fully slid into the grooved hollow block 205, the compression spring 2062 releases its elastic force, pushing the locking pin 2063 to slide along the inner wall of the U-shaped piece 2061. Finally, the locking pin 2063 passes through the inner wall of the grooved hollow block 205 and engages with the grooved short block 204, thus locking and fixing the control box 203. After installation, when the control box 203 needs to be disassembled for maintenance, pull the locking post 2063. The locking post 2063 slides along the inner wall of the U-shaped piece 2061.

At the same time, the compression spring 2062 on its outer wall is compressed. When the locking post 2063 is disengaged from the engaging position of the grooved short block 204 and completely disengaged from the inner wall of the grooved hollow block 205, the locking state is released. At this time, the grooved short block 204 can be slid directly out from the inner wall of the grooved hollow block 205, causing the control box 203 to separate from the meter body 1, quickly completing the disassembly and reducing maintenance time and cost.
