[0015] Compared with the prior art, this utility model provides a wastewater engineering reflux control device, which has the following beneficial effects:

[0016] (1) This utility model effectively solves the problem of impurities easily adhering to the lead screw and rusting in water in the prior art by setting a U-shaped dustproof frame and a dustproof outer frame. The first lead screw used to adjust the flow control is set inside the U-shaped dustproof frame, and the second lead screw used to drive the water quality monitor to rise and fall is stored inside the dustproof outer frame. Neither of them directly contacts the wastewater, which fundamentally avoids the lead screw being corroded by wastewater or blocked by impurities, and extends the service life of the device. In terms of specific linkage, when it is necessary to adjust the water flow in the tank, the control module will start the first motor. The first motor drives the first lead screw to rotate between the two positioning plates. The first threaded sleeve on the first lead screw will move along the first lead screw axis in the U-shaped dustproof frame. The first threaded sleeve drives the limit guide frame to move synchronously through the connecting plate. The limit guide frame pushes the first connecting rod to slide along the arc guide groove, thereby driving the flow control plate to rotate around the hinge frame, realizing the precise adjustment of the water flow speed and flow rate in the tank. The entire flow control drive All structures are located outside the enclosure, unaffected by wastewater. For water quality monitoring, the control module activates the second motor within the dustproof frame based on the water level signal from the float level gauge. This second motor drives the second lead screw to rotate between the positioning top plate and the dustproof frame. The second threaded sleeve on the lead screw causes the lifting plate to slide stably along the guide rod. The limiting plate at the bottom of the guide rod restricts the lowest position of the lifting plate, preventing the water quality monitor's probe from impacting the bottom inner wall of the enclosure and also preventing the second threaded sleeve from impacting the top of the second motor. The lifting plate, via the second connecting rod, raises and lowers the protective frame and the internal water quality monitor, allowing the monitor's probe to adapt to different water level detection requirements. The protective frame also provides collision protection for the water quality monitor. Furthermore, the control module, as the core control unit, receives water level data from the float level gauge and water quality data from the water quality monitor, automatically controlling the inlet switch of the first solenoid valve and the outlet switch of the second solenoid valve.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-4As shown, this utility model provides a wastewater engineering reflux control device, including a housing 1. A dustproof outer frame 19 is fixedly connected to the top side of the housing 1. A multi-functional slot 20 is opened on the bottom side of the dustproof outer frame 19. A second motor 21 is fixedly installed on the top side of the housing 1 and disposed in the multi-functional slot 20. The output end of the second motor 21 is connected to a second lead screw 22 through a coupling. The top end of the second lead screw 22 is rotatably connected to a positioning top plate 23 through a bearing. Guide rods 24 are fixedly connected to the bottom sides of both ends of the positioning top plate 23. The bottom ends of the guide rods 24 are fixedly connected to the inner wall of the dustproof outer frame 19. A second threaded sleeve 26 is installed on the second lead screw 22. A lifting plate 27 is fixedly connected to the second threaded sleeve 26. The two ends of the lifting plate 27 are slidably connected to the corresponding guide rods 24. Limiting plates 25 are fixedly connected to the bottom ends of the guide rods 24. Two second connecting rods 28 penetrating the housing 1 are symmetrically fixedly connected to the bottom side of the lifting plate 27. A protective frame 29 is fixedly connected between the bottom ends of the second connecting rods 28 away from the lifting plate 27. A water quality monitor 30 is fixedly installed on the bottom inner wall of the protective frame 29, and the monitoring probe of the water quality monitor 30 extends downward through the bottom of the protective frame 29. The dustproof outer frame 19 provides heat dissipation and space for the second motor 21 through the multi-functional slot 20. The second motor 21 can drive the second lead screw 22 to rotate. The positioning top plate 23 provides rotational support for the top of the second lead screw 22 to ensure its rotational stability. The guide rod 24 guides the movement of the lifting plate 27, preventing it from shifting as the second lead screw 22 rotates. The limiting plate 25 restricts the descent of the lifting plate 27, preventing excessive downward movement. The second threaded sleeve 26 cooperates with the second lead screw 22 to convert its rotational motion into linear motion, thereby driving the lifting plate 27 to move up and down. The lifting plate 27 drives the protective frame 29 to rise and fall synchronously with the water quality monitor 30 via the second connecting rod 28. The protective frame 29 protects the water quality monitor 30 from wastewater impact or impurities, while the water quality monitor 30 detects wastewater quality through its monitoring probe, providing water quality data for reflux control.

[0027] Example 2

[0028] Please see Figure 1 and Figure 3 A water inlet pipe 2 is fixedly connected to one side of the tank 1 via a flange. A first solenoid valve 3 with a water flow control switch is installed on the water inlet pipe 2. The water inlet pipe 2 is the channel for wastewater to enter the tank 1. The first solenoid valve 3 controls its own switch to regulate the flow of wastewater in the water inlet pipe 2, thereby controlling the amount of wastewater entering the tank 1.

[0029] Example 3

[0030] Please see Figure 2On the other side of the housing 1, a water outlet pipe 4 is symmetrically connected and fixed via a flange. Each water outlet pipe 4 is equipped with a second solenoid valve 5 with a control switch. The water outlet pipe 4 is used to discharge wastewater from the housing 1. The second solenoid valve 5 regulates the flow of wastewater in the water outlet pipe 4 by controlling its own on / off state.

[0031] Example 4

[0032] Please see Figures 1-3 A float level gauge 6 is fixedly installed on the top side of the tank 1, and the guide rod of the float level gauge 6 passes through the top side of the tank 1 and extends to the bottom of the tank 1. The float level gauge 6 monitors the liquid level of wastewater in the tank 1 through its guide rod and transmits the monitored liquid level information to the control module 31, providing liquid level data support for subsequent water flow control operations.

[0033] Example 5

[0034] Please see Figures 1-3 Two arc-shaped guide grooves 7 are symmetrically formed on the top side of the housing 1, and two hinge frames 8 are symmetrically fixed between the inner walls of the two sides of the housing 1. The hinge frames 8 provide a rotating mounting base for the flow control plate 9, allowing the flow control plate 9 to rotate around the hinge frames 8. The arc-shaped guide grooves 7 provide a guiding path for the movement of the first connecting rod 10 to match the rotation trajectory of the flow control plate 9, ensuring the smooth movement of the first connecting rod 10.

[0035] Example 6

[0036] Please see Figure 3 Each hinged frame 8 is rotatably mounted with a flow control plate 9. A first connecting rod 10 is fixedly connected to the top side of the flow control plate 9, and the first connecting rod 10 passes through the arc-shaped guide groove 7 and maintains a sliding connection with the arc-shaped guide groove 7. The flow control plate 9 changes the flow speed and direction of the wastewater in the tank 1 by adjusting its own angle, thereby controlling the water flow. When the first connecting rod 10 slides in the arc-shaped guide groove 7, it can drive the flow control plate 9 to rotate synchronously, transmitting power for the angle adjustment of the flow control plate 9.

[0037] Example 7

[0038] Please see Figure 1 , Figure 2 and Figure 5 The top side of the housing 1 is symmetrically and fixedly connected to two positioning plates 11. A first lead screw 12 is rotatably mounted between the two positioning plates 11 via bearings, and the first lead screw 12 is driven by a first motor 13 fixedly mounted on the outer wall of one of the positioning plates 11. The positioning plates 11 provide rotational support for the first lead screw 12, ensuring stable rotation of the first lead screw 12. The first motor 13 provides power for the rotation of the first lead screw 12, driving the first lead screw 12 to rotate between the two positioning plates 11.

[0039] Example 8

[0040] Please see Figure 1 , Figure 2 and Figure 5 A U-shaped dustproof frame 14, fixed between two positioning plates 11, is provided on the outer side of the first lead screw 12. A first threaded sleeve 15, disposed within the U-shaped dustproof frame 14, is installed on the first lead screw 12. A connecting plate 16 is fixedly connected to the bottom side of the first threaded sleeve 15. The U-shaped dustproof frame 14 provides dust protection for the first lead screw 12 and the first threaded sleeve 15, preventing impurities from adhering and affecting their coordinated movement. The first threaded sleeve 15 cooperates with the first lead screw 12 to convert the rotational motion of the first lead screw 12 into linear motion, which drives the subsequent components to move through the connecting plate 16.

[0041] Example 9

[0042] Please see Figure 1 , Figure 2 and Figure 5 The bottom end of the connecting plate 16 is fixedly connected to a limiting guide frame 17. The inner wall of the limiting guide frame 17 is slidably engaged with the top end of the first connecting rod 10, and the top end of the first connecting rod 10 is fixedly connected with two limiting blocks 18 disposed on both sides of the limiting guide frame 17 at intervals. The limiting guide frame 17 can convert the linear motion of the connecting plate 16 into the power to drive the first connecting rod 10 to slide along the arc-shaped guide groove 7, thereby driving the flow control plate 9 to rotate. The limiting blocks 18 restrict the relative position of the first connecting rod 10 and the limiting guide frame 17, preventing the first connecting rod 10 from disengaging from the limiting guide frame 17 and ensuring the stability of the transmission process.

[0043] Example 10

[0044] Please see Figure 1 and Figure 2 A control module 31 is fixedly installed on the top side of the housing 1. The control module 31 is electrically connected to the float level gauge 6, the first motor 13, and the second motor 21 via wires. The control module 31 is also wirelessly connected to the first solenoid valve 3, the second solenoid valve 5, and the water quality monitor 30. The control module 31 is the core of the entire device. It receives the liquid level information transmitted by the float level gauge 6 via wires and controls the start, stop, and operation status of the first motor 13 and the second motor 21. At the same time, it receives the water quality data from the water quality monitor 30 via wireless connection and controls the opening and closing of the first solenoid valve 3 and the second solenoid valve 5, realizing the automated control of wastewater inlet, outlet, return, and water quality monitoring.

[0045] The working principle of the wastewater engineering reflux control device provided by this utility model is as follows:

[0046] First, based on the wastewater treatment requirements, the control module 31 issues a command to open the first solenoid valve 3 on the inlet pipe 2, allowing wastewater to enter the tank 1 through the inlet pipe 2. At this time, the float level gauge 6 monitors the water level in the tank 1 in real time and transmits the water level signal to the control module 31 via a wire. Upon receiving the water level signal, the control module 31 starts the second motor 21 inside the multi-functional slot 20. The second motor 21 drives the second lead screw 22 to rotate, and the second lead screw 22 drives the second threaded sleeve 26 along the second lead screw 2... 2. Axial movement: The second threaded sleeve 26 drives the lifting plate 27 to move synchronously. Under the limiting action of the guide rod 24, the lifting plate 27 maintains horizontal lifting until it reaches the height set by the control module 31. The lifting plate 27 drives the protective frame 29 and the water quality monitor 30 inside the protective frame 29 to rise and fall together via the second connecting rod 28, so that the monitoring probe of the water quality monitor 30 extends into the wastewater inside the tank 1. The water quality monitor 30 wirelessly transmits the detected water quality signal to the control module 31. The control module 31 combines the water level signal and the water quality signal... The system determines whether water flow rate adjustment is needed. If adjustment is required, the first motor 13 on the outer side of the positioning plate 11 will be activated. The first motor 13 drives the first lead screw 12 to rotate. The first threaded sleeve 15 on the first lead screw 12 moves along the first lead screw 12 under the protection of the U-shaped dustproof frame 14. The first threaded sleeve 15 drives the limiting guide frame 17 to move through the connecting plate 16. The limiting guide frame 17 pushes the first connecting rod 10 to slide along the arc-shaped guide groove 7. The limiting block 18 on the first connecting rod 10 can prevent it from disengaging from the limiting guide frame 17. The first connecting rod 10 drives the flow control plate 9 to rotate around the hinge frame 8. By changing the angle between the flow control plate 9 and the inner wall of the tank 1, the speed and flow rate of the water in the tank 1 are adjusted. Finally, according to the water quality test results, if the water quality meets the standards, the control module 31 opens the second solenoid valve 5 on one of the outlet pipes 4, and the wastewater is discharged to the designated system through the outlet pipe 4. If the water quality does not meet the standards, the second solenoid valve 5 on the other outlet pipe 4 is opened, and the first solenoid valve 3 is closed. The wastewater is discharged after the water quality meets the standards, thus completing one wastewater return control process.

[0047] The metal structures involved in this utility model, such as motors and lead screws, must be made of high-quality rust-proof materials or treated with mature waterproofing processes. This is to effectively prevent device malfunctions caused by rust or water ingress in structural components. Since the aforementioned rust-proof materials and waterproofing processes are all within the scope of existing technology, they will not be described in detail in this utility model.
