Description

Technical Field

[0001] This utility model relates to the field of valve-controlled ultrasonic water meter technology, and in particular to an installation structure for NB-IoT valve-controlled ultrasonic water meters. Background Technology

[0002] The valve-controlled ultrasonic water meter is a smart water meter that combines ultrasonic metering technology and valve control functions with NB-IoT communication technology. It accurately measures water flow using ultrasound, avoiding the wear and tear problems of traditional mechanical water meters. Simultaneously, it utilizes NB-IoT technology for remote meter reading and real-time data transmission. This water meter has the function of remotely controlling the water valve, automatically cutting off or restoring water supply in case of abnormalities, and is widely used in smart water management. To ensure stable installation and normal operation, a suitable installation structure is required.

[0003] The installation structure for NB-IoT valve-controlled ultrasonic water meters typically includes specially designed brackets, connectors, and housings to ensure that the water meter is securely installed in the piping system. In existing technologies, the two ends of the water meter are usually equipped with standard threaded interfaces that are directly connected to the pipe. The installation is carried out by utilizing the tightness of the threads. This method cannot reduce the possibility of the water meter shifting or loosening due to water flow impact or external forces. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an installation structure for NB-IoT valve-controlled ultrasonic water meters, aiming to improve the problem that the installation structure cannot reduce the displacement or loosening of the water meter due to water flow impact or external force during use.

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

[0006] An installation structure for an NB-IoT valve-controlled ultrasonic water meter includes a base. A bidirectional lead screw is rotatably connected inside the base. A handle is fixedly connected to the outer wall of the bidirectional lead screw. A moving block is threadedly connected to the outer wall of the bidirectional lead screw. A slide rail is fixedly connected to the lower surface of the moving block. A slide seat is slidably connected to the outer wall of the slide rail. The outer wall of the slide seat is fixedly connected to the inner bottom wall of the base. A clamping block is fixedly connected to the upper surface of the moving block. A water meter body is mounted on the outer wall of the clamping block. A threaded tube is mounted on the inner wall of the water meter body. A limit component is provided on the outer wall of the bidirectional lead screw to restrict its rotation.

[0007] Preferably, the limiting component includes a ratchet, the ratchet is internally fixedly connected to the outer wall of the bidirectional lead screw, the teeth of the ratchet are engaged with a pawl, the pawl is internally rotatably connected to the outer wall of the base, and a spring is fixedly connected to the lower surface of the pawl, the lower outer wall of the spring being fixedly connected to the outer wall of the base.

[0008] Preferably, both outer walls of the base are fixedly connected to a fixing plate, and a sliding rod is slidably connected inside the fixing plate.

[0009] Preferably, a trapezoidal block is fixedly connected to the rear outer wall of the slide rod, and a limit block is slidably connected to the rear outer wall of the trapezoidal block.

[0010] Preferably, a protective cover is fixedly connected to the outer wall of the limiting block, and the lower surface of the protective cover is disposed on the upper surface of the base.

[0011] Preferably, a second spring is fixedly connected to the front outer wall of the trapezoidal block, and the front outer wall of the second spring is fixedly connected to the rear outer wall of the fixing plate.

[0012] Preferably, a second slide block is fixedly connected to the lower surface of the trapezoidal block, and a second slide rail is slidably connected to the inner wall of the second slide block.

[0013] Preferably, the front outer wall of the slide rail 2 is fixedly connected to the rear outer wall of the fixing plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the handle, the bidirectional lead screw is driven to rotate forward, which drives the moving block to move towards the center of the bidirectional lead screw. The slide rail slides to the right on the inner wall of the slide block. The moving block drives the clamping block to move to the right to fix the water meter body, which prevents the water meter body from being displaced or loosened due to water flow impact or external force. At the same time, it also improves the convenience of installation and disassembly.

[0016] 2. In this utility model, by pulling the slide rod, the trapezoidal block moves forward, which compresses the second spring and causes the second slide block to slide forward on the outer wall of the second slide rail. The second slides out of the inner wall of the limiting block through the outer wall of the trapezoidal block, achieving the effect of quickly disassembling the protective cover. This reduces the maintenance costs caused by damage to the protective cover or improper installation, thereby reducing long-term maintenance costs. Attached Figure Description

[0025] Specifically, the base 1 provides support for the rotation of the bidirectional lead screw 2, the handle 3 facilitates operation of the bidirectional lead screw 2, the thread of the bidirectional lead screw 2 drives the moving block 4, the slide block 6 limits the sliding of the slide rail 5, thus limiting the movement of the moving block 4, the moving block 4 drives the clamping block 7 to move left and right, thus releasing or fixing the water meter body 8, the spring 12, the ratchet 10 and pawl 11 rotate the bidirectional lead screw 2 forward to achieve a self-locking effect, the pawl 11 moves downward by pressing, the pawl 11 leaves the tooth end of the ratchet 10 under the action of the outer wall of the base 1, allowing the bidirectional lead screw 2 to rotate backward.

[0026] Reference Figure 4 The base 1 has fixed plates 13 on both outer walls, and the fixed plates 13 have sliding rods 14 inside.

[0027] Specifically, the base 1 fixes the fixing plate 13, and the fixing plate 13 limits the sliding of the slide rod 14.

[0028] Reference Figure 4 A trapezoidal block 15 is fixedly connected to the rear outer wall of the slide rod 14, and a limit block 19 is slidably connected to the rear outer wall of the trapezoidal block 15; a protective cover 20 is fixedly connected to the outer wall of the limit block 19, and the lower surface of the protective cover 20 is set on the upper surface of the base 1; a second spring 16 is fixedly connected to the front outer wall of the trapezoidal block 15, and the front outer wall of the second spring 16 is fixedly connected to the rear outer wall of the fixing plate 13; a second slide block 17 is fixedly connected to the lower surface of the trapezoidal block 15, and a second slide rail 18 is slidably connected to the inner wall of the second slide block 17; the front outer wall of the second slide rail 18 is fixedly connected to the rear outer wall of the fixing plate 13.

[0029] Specifically, pulling the slide rod 14 achieves the transmission effect on the trapezoidal block 15, the second spring 16 achieves the connection between the fixed plate 13 and the trapezoidal block 15, the sliding of the trapezoidal block 15 achieves the limiting or releasing effect on the limiting block 19, the fixed plate 13 achieves the fixing effect on the second slide rail 18, the second slide rail 18 achieves the supporting effect on the sliding of the second slide seat 17, and thus the sliding of the fixed plate 13 and the second slide seat 17 on the trapezoidal block 15 achieves the supporting and offset limiting effect. The inner wall of the limiting block 19 has multiple grooves for adjusting the installation height of the protective cover 20 to adapt to different environments and installation requirements.

[0030] Working principle: When using this structure, place the water meter body 8 within the range of the clamping block 7, turn the handle 3, and drive the double-acting screw 2 to rotate forward inside the base 1. Under the action of the double-acting screw 2, the moving block 4 moves towards the center of the double-acting screw 2. Through the slide rail 15 sliding on the inner wall of the slide block 6, the movement of the moving block 4 is limited. The moving block 4 drives the clamping block 7 to move towards the center of the double-acting screw 2, clamping and fixing the water meter body 8, ensuring that the water meter body 8 maintains a stable position during operation. Through the ratchet 10 and pawl 11, under the action of the spring 12, the rotation of the double-acting screw 2 achieves a self-locking effect. After fixing, it is connected to the pipeline through the threaded pipe 9. When the water meter body 8 is not in use, pull the slide rod 14 to drive the trapezoidal block 15 forward, which in turn controls the movement of the spring 12. 6. The slide block 15 is pressed and slides on the outer wall of the slide rail 18 via the slide block 17, which restricts the movement of the trapezoidal block 15. The protective cover 20 is then attached to the base 1. When the limiting block 19 moves to the appropriate position, the slide rod 14 is released. Under the elastic force of the spring 16, the trapezoidal block 15 slides backward and slides into the inner wall of the limiting block 19 to limit the protective cover 20. This achieves the effect of quickly installing and removing the protective cover 20. During use, this structure not only quickly fixes the water meter body 8, reducing wear or damage caused by frequent vibration or movement, thereby extending the service life of the water meter body 8, but also enables quick installation and removal of the protective cover 20, reducing the entry of moisture, debris, or airborne particles into the interior of the water meter body 8, and preventing damage to the water meter sensor and electronic components.
