[0001] This utility model relates to the field of monitoring and alarm technology for pressure surges in water supply pipelines, specifically a monitoring and alarm mechanism for pressure surges in underground water supply pipelines. Background Technology

[0002] The water supply pipeline pressure surge monitoring and alarm device is mainly used to monitor pipeline pressure changes in real time. When the pressure in the pipeline exceeds or falls below the preset safety range, the alarm will sound to remind the operator to take appropriate measures to prevent pipeline rupture, leakage or other accidents.

[0003] Existing monitoring and alarm devices typically have wire harness insertion holes at the bottom for connecting wire harnesses to internal electrical components. However, the diameter of these insertion holes is usually fixed. When a small number of wire harnesses are inserted, there are still many gaps between the wire harnesses and the insertion holes, which can easily lead to a large amount of dust entering the device and causing damage to the internal electrical components.

[0004] Therefore, a monitoring and alarm mechanism for pressure surges in underground water supply pipelines is proposed to solve the problems mentioned above. Utility Model Content

The first sliding block 6 is slidably connected inside the first sliding groove 5. The shaped block 7 is fixedly connected to the top of the first sliding block 6. The fixed column 8 is fixedly connected to the top of the irregular block 7. The turntable 9 is set on the top of the irregular block 7. The second sliding groove 10 is opened through the top of the turntable 9. The toothed groove 11 is opened on the side of the turntable 9. The monitoring and alarm device 1 is equipped with a limit mechanism inside. The irregular block 7 is made of rubber. The monitoring and alarm device 1 can monitor the pressure change data of the underground water supply pipeline. When the threshold is exceeded, an alarm is triggered to achieve the effect of monitoring and alarm. It is the existing technology in this field. The structure and working principle of the monitoring and alarm device 1 are existing technologies and will not be described in detail here. The model of the monitoring and alarm device 1 is: LY-PA3000.

[0020] In use, the wire harness passes through the wire hole 3 and connects to the internal electrical components of the monitoring and alarm device 1. By turning the turntable 9, the irregularly shaped block 7 slides inward and closes tightly to the wire harness, positioning the wire harness and blocking the wire hole 3. Then, the insert plate 17 is inserted into the toothed groove 11 to fix the turntable 9. By adjusting the closed state of the irregularly shaped block 7, the thickness or number of wire harnesses can be adapted to the wire harness, positioning the wire harness and blocking the wire hole 3 to prevent dust from entering the monitoring and alarm device 1 and to protect the internal electronic components of the monitoring and alarm device 1.

[0021] Please see Figures 1-4 The first slide groove 5 is a T-shaped structure, and the inner wall of the first slide groove 5 is in contact with the outer wall of the first slider 6. The fixing post 8 is slidably connected inside the second slide groove 10, and the inner wall of the second slide groove 10 is in contact with the outer wall of the fixing post 8.

[0022] For better fixation, the limiting mechanism includes a fixing block 12, a fixing groove 13, a guide rod 14, a spring 15, a second slider 16, an insert plate 17, a groove 18, a fixing frame 19, and a protrusion 20. The fixing block 12 is fixedly connected inside the monitoring alarm device 1. The fixing groove 13 is opened on the inner side of the fixing block 12. The guide rod 14 is fixedly connected inside the fixing groove 13. The spring 15 is sleeved on the outer side of the guide rod 14. The second slider 16 is slidably connected to the outer side of the guide rod 14. The insert plate 17 is fixedly connected to one side of the second slider 16. The groove 18 is opened on the top of the second slider 16. The fixing frame 19 is fixedly connected to the top of the fixing block 12. The protrusion 20 is fixedly connected to the end of the fixing frame 19.

[0023] Before rotating the turntable 9, pull the fixing bracket 19 upwards. The fixing block 12 at one end will disengage from the groove 18. Then slide the second slider 16 and insert the fixing block 12 at the other end of the fixing bracket 19 into the groove 18 to fix the second slider 16. After the turntable 9 is adjusted, the second slider 16 is reset in the opposite direction. It is then inserted into the toothed groove 11 through the insert plate 17 to achieve the effect of stopping the rotation of the turntable 9 and ensuring that the irregular block 7 is in close contact with the wire harness, thus achieving a better protection effect.

[0024] Please see Figure 5 The outer wall of the protrusion 20 fits into the inner wall of the groove 18, and one end of the insert plate 17 is set with a tapered structure.

[0025] Please see Figure 6 The monitoring and alarm device 1 has a first cable tray 21 fixedly connected to its bottom. A second cable tray 22 is provided on one side of the first cable tray 21. Fixing holes 23 are provided on the inner sides of both the first cable tray 21 and the second cable tray 22. Limiting posts 24 are inserted into the inner side of the fixing holes 23.

[0026] The second wire harness plate 22 is snapped into the connecting post 28 on the outside of the first wire harness plate 21 via the side plate 27, which enables the second wire harness plate 22 to be quickly fixed and is easier to disassemble and assemble. At this time, a wire harness hole is formed at the joint of the first wire harness plate 21 and the second wire harness plate 22, and the protective pad 25 inside the wire harness hole can play a clamping and protective role for the wire harness, and better fix the wire harness. The arc surface 26 can prevent the wire harness from being worn.

[0027] Please see Figure 6 The limiting post 24 is designed with an umbrella-shaped structure, and the outer wall of the limiting post 24 fits against the inner wall of the fixing hole 23.

[0028] The working principle of the above embodiments is as follows: In use, the wire harness passes through the wire hole 3 and connects to the internal electrical components of the monitoring and alarm device 1. By turning the turntable 9, the irregular block 7 slides inward and closes tightly to the wire harness, positioning the wire harness and blocking the wire hole 3. Then, the insert plate 17 is inserted into the toothed groove 11 to fix the turntable 9. By adjusting the closed state of the irregular block 7, the thickness or number of wire harnesses can be adapted to the wire harness, positioning the wire harness and blocking the wire hole 3 to prevent dust from entering the monitoring and alarm device 1 and to protect the internal electronic components of the monitoring and alarm device 1. Before rotating the turntable 9, pull the fixing bracket 19 upwards. The fixing block 12 at one end will disengage from the groove 18. Then slide the second slider 16 and insert the fixing block 12 at the other end of the fixing bracket 19 into the groove 18 to fix the second slider 16. After the turntable 9 is adjusted, the second slider 16 is reset in the opposite direction. It is inserted into the toothed groove 11 through the insert plate 17 to achieve the effect of stopping the rotation of the turntable 9 and ensuring that the irregular block 7 is in close contact with the wire harness, thus achieving a better protection effect. The second wire harness plate 22 is snapped into the connecting post 28 on the outside of the first wire harness plate 21 via the side plate 27, which enables the second wire harness plate 22 to be quickly fixed and is easier to disassemble and assemble. At this time, a wire harness hole is formed at the joint of the first wire harness plate 21 and the second wire harness plate 22, and the protective pad 25 inside the wire harness hole can play a clamping and protective role for the wire harness, and better fix the wire harness. The arc surface 26 can prevent the wire harness from being worn.
