For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0029] As Figure 1As shown, a plant road rainwater discharge monitoring device, including a plurality of distribution in the plant road surface on the sewer 1, set in the underground rainwater pipe 2, with the river 26 communication drainage pipe 3, water storage tank 4, controller (not shown in the figure), PH online detector 5, each sewer lower end is communicated with rainwater pipe, rainwater pipe and water storage tank communication, water storage tank one side lower part is equipped with drainage outlet 6, drainage outlet connects drainage pipe, rainwater pipe, drainage pipe are inclined to set, rainwater pipe connects water storage tank one end height is lower than the height of the other end, drainage pipe connects river one end height is lower than the height of the other end, it is convenient for rainwater to enter the water storage tank by rainwater pipe, and into the river through the water storage tank. The drainage outlet is provided with an electric valve for controlling the drainage amount, and the detection probe of the PH online detector is arranged on the inside bottom of the water storage tank. The PH online detector and the electric valve are electrically connected with the controller. In the embodiment, the controller adopts a PLC controller. The PH value can be preset according to the requirement. When the PH value of the rainwater in the water storage tank detected by the PH online detector is equal to or lower than the preset value, the controller provides a closing instruction for the electric valve, so as to avoid the acidic rainwater from flowing into the river and affecting the river ecology. When the PH value of the rainwater in the water storage tank detected by the PH online detector is higher than the preset value, the controller provides an opening instruction for the electric valve. At this time, the rainwater in the water storage tank can flow into the river through the drainage pipe freely, so as to realize the linkage control of the PH value and the electric valve. A submersible pump 15 is arranged in the water storage tank. A sewage pipe 16 is connected to the submersible pump. The sewage pipe is connected with a sewage treatment system in the plant and is used for conveying sewage into the sewage treatment pipe network system and treating the sewage by the sewage treatment system. The submersible pump is electrically connected with the controller. When the PH value of the rainwater in the water storage tank is relatively low and is not suitable for discharge, the submersible pump can be started at this time to convey the rainwater in the water storage tank to the sewage treatment system through the sewage pipe, so as to facilitate the subsequent treatment work and discharge after treatment. If necessary, the PLC controller can be connected with a computer or a mobile phone to realize remote PH monitoring and electric valve control, and use is more convenient.
[0030] As shown in Figure 3 and Figure 4 The electric valve includes a support 7, a gate plate 8, a sliding groove 9 and an electric push rod 10. The support is provided with the sliding groove and a drainage hole 11. The shape and size of the drainage hole are consistent with the drainage outlet. The gate plate is connected with the sliding groove in an up-down sliding mode and cooperates with the drainage hole. The electric push rod is arranged on the support and the output shaft of the electric push rod is connected with the gate plate. The electric push rod controls the lifting of the gate plate, so as to adjust the water discharge amount of the drainage hole and the drainage outlet, which can effectively meet the rainwater discharge requirement in heavy rain and storm weather. The inner wall of the sliding groove is provided with a sealing pad 12 to avoid water leakage in the closed state of the gate plate. The upper end of the gate plate is symmetrically provided with two guide rods 13. Each guide rod is connected with a guide hole 14 arranged at the top end of the support in a sliding mode, which can effectively improve the stability of the gate plate in the lifting process.
[0031] As shown in Figure 1As shown, to facilitate the maintenance of the submersible pump, electric valve, and online pH meter in the water storage tank, a maintenance well 17 connected to the ground is provided at the upper end of the water storage tank. A climbing ladder 18 is installed on the inner wall of the maintenance well to facilitate maintenance personnel entering the water storage tank for maintenance work. Combined with... Figure 2 As shown, both the maintenance well and the sewer well have a first placement groove 19 at the top opening, with a well cover 20 inside. The well cover has at least one drain outlet 21, through which rainwater enters the maintenance well and sewer well. A second placement groove 22 is also provided at the top opening of both the maintenance well and the sewer well, located below the first placement groove. The second placement groove contains a filter screen located below the well cover, effectively filtering the incoming rainwater and preventing debris such as leaves and stones from entering the maintenance well and sewer well, thus preventing blockages in the rainwater pipes and drainage pipes. Combined with... Figure 5 As shown, the filter screen includes a fixed ring 23, a wing plate 24, and a filter screen 25. The wing plate is located on the outer periphery of the fixed ring, and its shape and size match the second placement groove. The upper end of the filter screen is connected to the fixed ring, and its vertical cross section is U-shaped. The manhole cover and the filter screen are easy to assemble and disassemble, and can be directly placed in the first placement groove and the second placement groove respectively.
[0032] The working principle of this utility model is as follows:
[0033] like Figures 1 to 5 As shown, during rainy or snowy weather, rainwater from various roads in the factory area enters the drains in manholes 1 and 17 through the drain covers. Filter screens effectively filter debris such as leaves and stones from the rainwater, preventing blockages in the rainwater pipes 2 and 3. The filtered rainwater flows into the storage tank 4 through the rainwater pipe 2. The pH online detector 5 monitors the pH value of the rainwater in the storage tank 4 in real time. When the pH value is equal to or greater than the preset value, the electric valve is open, and the rainwater in the storage tank 4 flows into the river through the drain pipe 3. When the pH value is less than the preset value (e.g., in the event of a yellow water leak, yellow water enters the storage tank from the drains and 17), a signal is fed back to the controller. The controller sends a command to the electric valve to close it. At this time, the rainwater with a lower pH value will not continue to flow into the river, avoiding impact on the river's ecology. At the same time, the submersible pump 15 is activated to transport the rainwater in the storage tank to the factory's wastewater treatment system through the sewage pipe 16, facilitating further treatment of the rainwater with a lower pH value before discharge, thus reducing environmental risks.
[0034] The basic principle and main features of the present application and the advantages of the present application are shown and described above, for those skilled in the art, obviously the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
