Detailed Implementation

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] According to wastewater monitoring indicators, multiple types of sensors are required for monitoring. These generally include nine main monitoring parameters: pH, COD (Chemical Oxygen Demand), ammonia nitrogen, suspended solids, turbidity, color, petroleum hydrocarbons, total phosphorus, and total nitrogen. Correspondingly, there are nine types of monitoring sensors. Due to their different functions, these sensors vary in structure, size, material, and weight, sometimes significantly. Substation wastewater discharge passes through wastewater ponds, which are typically semi-enclosed structures with maintenance access ports, which are usually closed. Therefore, to achieve effective wastewater monitoring, the monitoring device must be highly integrated and able to float on the water surface to enable long-term online monitoring in the complex wastewater pond environment.

[0032] Based on the above problems, the present invention provides the following embodiments:

[0033] Example 1:

[0034] This utility model provides a wastewater monitoring device for pumped storage power stations, based on... Figures 1-7 As shown, the device includes: a mounting plate 1, with a first mounting plate 2 and a second mounting plate 3 spaced apart below the mounting plate 1. The centers of the first mounting plate 2, the second mounting plate 3, and the mounting plate 1 are all connected by a connecting rod 4, and reinforcing rods 5 are evenly distributed on both sides of the connecting rod 4.

[0035] Multiple mounting holes 6 of different opening sizes are spaced through the first mounting plate 2 and the second mounting plate 3. Each mounting hole 6 is used to install a wastewater monitoring sensor 9.

[0036] Mounting plate 1 has mounting holes 7 at both ends. The mounting holes 7 are used to fix mounting plate 1 to the top of floating shell 8. Floating shell 8 is an annular shell. The inner annular hole of the shell is used to hold the first mounting plate 2 and the second mounting plate 3, and is used so that when the monitoring device is placed in wastewater, the detection end of its wastewater monitoring sensor 9 is located in the wastewater.

[0037] And, when the monitoring device is placed in wastewater, the detection end of its wastewater monitoring sensor 9 collects sensing data of the wastewater.

[0038] In this utility model, by using the first mounting plate 2 and the second mounting plate 3 in an alternating design, multiple mounting holes 6 of different diameters are evenly distributed on the first mounting plate 2 and the second mounting plate 3. The mounting holes of different diameters are used to install or clamp different wastewater monitoring sensors 9, thereby integrating multiple different wastewater monitoring sensors 9 into one unit. The reinforcing rods 5 evenly distributed on both sides of the connecting rod 4, the combination of the three rods, realize the installation plate 1, the first mounting plate 2 and the second mounting plate 3 in an alternating fixed unit. The first mounting plate 2 and the second mounting plate 3 are used to install wastewater monitoring sensors 9 of different sizes at staggered heights, thereby achieving the purpose of integrating different sensors into one unit.

[0039] The integrated wastewater monitoring sensor 9 is then inserted into the inner ring hole in the center of the floating shell 8 through the mounting plate 1. The floating shell 8 and the mounting plate 1 are then fastened together with screws at the top, so that the two can be connected as one unit.

[0040] When the floating shell 8 is placed in the wastewater tank, the floating shell can float on the surface. However, because the wastewater monitoring sensor 9 is placed in the inner ring, the wastewater can enter the inner ring, allowing the wastewater monitoring sensor 9 to monitor the wastewater, thereby achieving the purpose of wastewater monitoring sensor integration and facilitating its convenient management during daily maintenance and repair.

[0041] Example 2:

[0042] like Figure 1 , Figure 2 As shown, the bow-shaped plate 10 is mounted on the top of the floating housing 8 through the mounting holes 7 at both ends. The inner bottom of the floating housing 8 is provided with a counterweight base 14; the top of the wastewater monitoring sensor 9 is fixedly connected to the first mounting plate 2 and / or the second mounting plate 3 by bolts 16.

[0043] The floating shell 8 is made of rigid polyethylene plastic and is hollow inside. It has an air injection hole 18 at the top, which is used to inject gas into the hollow interior and seal the cavity of the hollow structure. The air injection hole 18 is sealed by a cap 13.

[0044] The monitoring device is attached to the assembly hole 7 at the top center of the bow-shaped plate 10 by a rope and floats on the surface of the wastewater in the wastewater pool 19.

[0045] Both the first mounting plate 2 and the second mounting plate 3 are provided with wire holes 17, which are used for the wire harness 15 of the wastewater monitoring sensor 9 to pass through.

[0046] The wiring harness 15 of the wastewater monitoring sensor 9 is joined at the top of the bow plate 10 and then placed in the corrugated pipe 11. After being protected by the corrugated pipe 11, it is led out of the wastewater pool 19 and electrically connected to the control box 12.

[0047] In this scheme, when the monitoring device is placed in the wastewater pool, its floating position is uncertain, which is convenient for management. The bow-shaped plate 10 is used to connect the floating shell 8, and the bow-shaped plate 10 is provided with an assembly hole 7, which is used to install ropes or fixing rods. This makes it easy to lift the monitoring device in the wastewater pool 19 for inspection and maintenance at any time, and avoids it from floating uncertainly in the wastewater pool and being difficult to retrieve.

[0048] Furthermore, by setting a counterweight base 14 at the bottom of the floating shell 8, the bottom of the floating shell 8 is always in the water pool when it floats in the wastewater pool 19, reducing the chance of it tipping over. Therefore, it is also ensured that the detection end of the wastewater monitoring sensor 9 can always be in the wastewater to monitor the wastewater.

[0049] When in use, the wire hole 17 can also introduce wastewater into the central inner ring of the floating shell 8, which can ensure that the detection end of the wastewater monitoring sensor 9 is in contact with the wastewater and achieve the monitoring purpose. Since the floating shell 8 is filled with gas (such as nitrogen or air), it can float on the water. In addition, the bottom of the floating shell 8 is designed with a counterweight base 14, which can submerge part of the floating shell 8 into the wastewater. In this way, the detection device can always float with the water surface to monitor the wastewater.

[0050] Since the first mounting plate 2 and the second mounting plate 3 are spaced apart, and there are multiple wastewater monitoring sensors 9, this design results in too many wire harnesses 15 for the wastewater monitoring sensors 9. In particular, when the wire harnesses 15 of the second mounting plate 3 are led upwards, the wire harnesses 15 can be led out through the wire holes 17 on the first mounting plate 2 and the second mounting plate 3 to avoid the wire harnesses 15 being squeezed and damaged in the central inner ring of the floating shell 8. Then, after all the wire harnesses 15 converge and are led out from above the mounting plate 1, they are wrapped with corrugated pipes 11 to protect the entire wire harness. After being protected by the corrugated pipes, the wire harnesses 15 are connected to the control box 12 through the terminal module. The control box 12 is installed vertically or wall-mounted on the outside of the wastewater tank and is used to display and transmit the data information collected in the wastewater tank to the monitoring center.

[0051] Example 3:

[0052] like Figures 1-7As shown, there are multiple wastewater monitoring sensors 9, all of which are vertically mounted on the first mounting plate 2 and / or the second mounting plate 3.

[0053] Wastewater monitoring sensors 9 include at least: pH value detection sensor, COD sensor, ammonia nitrogen sensor, suspended solids concentration sensor, turbidity sensor, color sensor, oil in water detection sensor, and total phosphorus and total nitrogen sensor.

[0054] In this scheme, when installing the wastewater monitoring sensor 9, the larger wastewater monitoring sensor 9 is mounted on the first mounting plate 2 with bolts 16, and the acquisition end passes through the second mounting plate 3; the smaller wastewater monitoring sensor 9 is mounted on the second mounting plate 3 with bolts 16. In this way, the acquisition ends of wastewater monitoring sensors 9 of different sizes are all located at the lower end of the second mounting plate 3, which is conducive to better and more accurate collection of wastewater monitoring data in the wastewater pool.

[0055] Example 4:

[0056] like Figures 5-6 As shown, the control box 12 includes: a box body, in which a communication module 20, an equipment debugging interface 24, a display module 25, a data acquisition module 21, and an industrial control computer 22 are installed at intervals via a back panel. The industrial control computer 22 is electrically connected to the communication module 20, the equipment debugging interface 24, the display module 25, and the data acquisition module 21, respectively. The data acquisition module 21 is connected to a monitoring device via a wiring harness 15. The industrial control computer 22, the communication module 20, the display module 25, and the data acquisition module 21 are all electrically connected to a power supply module 26 via a circuit breaker 23.

[0057] In this embodiment, the industrial control computer 22 is connected to the display module 25 to display the data acquisition information; the power supply module 26 uses the circuit breaker 23 to supply power and / or cut off power to the industrial control computer 22, the communication module 20, the display module 25, and the data acquisition module 21.

[0058] The input end of the data acquisition module 21 is connected to the wastewater monitoring sensor 9 via the wiring harness 15, and the output end of the data acquisition module 21 is connected to the industrial control computer 22 via the wiring harness 15. The industrial control computer 22 is connected to the equipment debugging interface 24 via the wire, which is used to debug the monitoring parameters (e.g., serial port data debugging) through the equipment debugging interface 24. The communication module 20 is connected to the industrial control computer 22 via the wire, so as to transmit the collected data to the monitoring center or host computer through the communication module 20.

[0059] It should be noted that the data processing and judgment involved in this utility model are all existing technologies. Its core lies in the integrated design of the monitoring device based on the existing monitoring mode, without improving the software control method.

[0060] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
