[0039] Furthermore, the fixed installation structure includes a water pipe mounting block 9, slot 20, and L-shaped snap-fit ​​groove 12. The interface positions between the water pump 6, electric valve 7, and pressure transmitter 8 and the pipeline are all connected to the water pipe mounting block 9. The inner surface of the water pipe mounting block 9 is fixedly connected to the outer surface of the pipeline. One end of the water pipe mounting block 9 is flush with the interface end of the pipeline. Slot 20 is opened on the side of the water pipe mounting block 9 that is flush with the interface end of the pipeline. Two L-shaped snap-fit ​​grooves 12 are opened on the end of the water pipe mounting block 9 where slot 20 is opened. The L-shaped snap-fit ​​grooves 12 are evenly distributed along the circumference of the inner surface of the water pipe mounting block 9. The L-shaped snap-fit ​​grooves 12 connect the outside of the water pipe mounting block 9 and slot 20. The water pipe mounting block 9 is used to connect the water pump 6, electric valve 7, and pressure transmitter 8 to the pipeline. Slot 20 is used to install the fixed pipe structure.

[0046] Furthermore, the side of the slot 13 that mates with the spherical protrusion 18 is provided with a plurality of circumferentially evenly distributed spherical grooves 19. The number and distribution of the spherical grooves 19 are the same as those of the spherical protrusion 18. The spherical grooves 19 and the spherical protrusion 18 are snapped together.

[0073] Working Principle: Pump Station A 1 has a 4.5-meter deep water pool equipped with a 5-meter guided wave radar level gauge for real-time water level monitoring. The pump house is underground and houses two water pumps 6, as well as a wireless water level meter. When the water level meter detects a level higher than 0.1 meters, it will interlock and start a submersible pump to prevent underground water accumulation from damaging the equipment. Pump Station A 1 is connected to Pump Station B via two sets of water pipes 4. Two electric valves 7 and two pressure transmitters 8 are installed on water pipes 4 to regulate and monitor water flow. In addition, Pump Station A 1 is also equipped with two control and display terminals and four 4-channel digital displays to achieve real-time display and control of equipment operating data. The interlocking rules are as follows: when the water level in the pool is below 0.5 meters, pumps #1 and #2 will stop operating. Pump station C (3) has a 5-meter deep water pool, also equipped with a 5-meter guided wave radar level gauge to monitor the water level. The pump house is underground, and the two water pumps (6) use frequency converter starting. It is equipped with a wireless water level gauge; when the water level is above 0.1 meters, one submersible pump will be interlocked to start and stop. Pump station C (3) lays two water pipe sets (25) to pump station B. Two electric valves (7) and two pressure transmitters (8) are installed on water pipe sets (25), along with two control and display terminals and three 4-channel digital displays. The interlocking rules for pump station C (3) are as follows: when the water level in the pool is below 0.1 meters, pumps #1 and #2 will stop operating. Pump station B includes... Three interconnected water tanks, each 5 meters deep (tank A2, tank C21, and tank B23), are equipped with a 5-meter guided wave radar level gauge in each tank. The pump station is underground and equipped with four water pumps 6, each started by a frequency converter. Water is transported to tank D22 via four water pipe groups 4 25. Two water pipe groups 4 25 connected to tank A2 are equipped with two electric valves 7 and two pressure transmitters 8, while the other two water pipe groups 4 25 are not equipped with related equipment. Pump station B is equipped with a Heima PLC cabinet containing a Siemens S7-200CN, a Heima cloud box, a 4G wireless terminal, and a Hikvision 4G high-definition monitoring system. Their interlocking... The rule is that when the water level in the pool is below 0.5 meters or above 3.5 meters, pumps 1 / 2 / 3 / 4 will stop operating. Regarding the integrated control and interlocking of the three pump stations (A, B, and C), the configuration data of stations A and C are directly uploaded to Aotai Cloud via four sets of 4G remote terminals. The water level signal from station B is transmitted to Aotai Cloud via a safety barrier. The configurations of the three stations are then combined to achieve unified control. Simultaneously, mobile and PC applications are developed to enable real-time data updates and central control operation. Furthermore, an interlocking mechanism is in place between stations A, B, and C. When the water level in pool 1 of pump station B reaches 4 meters, all pumps in pump stations A and C will be interlocked and stopped.

[0074] The interfaces of water pipe assembly 4 and water pipe assembly 5, which are installed with water pump 6, electric valve 7, and pressure transmitter 8, are respectively connected to water pipe mounting block 9 and instrument mounting block 10. The inner surface of water pipe mounting block 9 is fixed to the outer surface of the water pipe assembly, and one end of it has slot 20 and L-shaped snap-fit ​​groove 12. The inner surface of instrument mounting block 10 is fixed to the outer surface of the instrument, and the corresponding end has slot 13. Fixing tube 11 is inserted into slot 20, and one end of it in slot 20 is connected to spring 14. The other end of spring 14 is in contact with the opposite surface of the opening of slot 20. Fixing tube 11 is inserted into slot 20. One end of spring 11 in slot 20 is connected to spring 14. The other end of spring 14 is in contact with the opposite surface of the opening of slot 20. One end of the second slot 20 is inserted into slot 13 of the instrument mounting block 10. The spring force of spring 14 causes the fixing tube 11 to be simultaneously inserted into slot 13 and slot 20, achieving connection and sealing between the water pipe mounting block 9 and the instrument mounting block 10. The locking rod 15 is aligned with the vertical portion of the L-shaped locking groove 12, and the fixing tube 11 is pushed to slide the locking rod 15 along the vertical L-shaped locking groove 12. At this time, spring 14 is compressed. When the locking rod 15 slides to the horizontal portion of the L-shaped locking groove 12, spring 14 returns to its original position, and the fixing tube 11 is inserted into slot 20 and slot 20. Within slot 13, the water pipe assembly and instrument assembly are quickly installed. When disassembly is required, pushing the fixing tube 11 causes the locking rod 15 to slide within the horizontal L-shaped locking groove 12. Spring 14 is compressed, and the fixing tube 11 fully enters slot 20, allowing easy separation of the water pipe assembly and instrument assembly. One end of the fixing tube 11 within slot 13 has a telescopic groove 16. Spring 17 and a spherical protrusion 18 are installed within the telescopic groove 16. The elasticity of spring 17 causes the spherical protrusion 18 to extend out of the telescopic groove 16 and engage with the spherical groove 19 within slot 13, thus locking slot 13. 13 and fixed pipe 11 prevent easy rotation and ensure connection stability. The base station control system controls the water pump 6, electric valve 7 and pressure transmitter 8 on water pipe group 1 4 and water pipe group 2 5. The system collects the operating data of each instrument in real time (such as the operating status of water pump 6, the on / off status of electric valve 7, pipeline pressure, etc.) through sensors and transmits it to the control system. The control system analyzes and processes the data according to the preset logic and algorithm, and automatically adjusts the start and stop of water pump 6, the opening degree of electric valve 7, etc., to realize intelligent control of the drainage water supply system and ensure the stable operation of the system.
