Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically a three-valve well discharge monitoring device. Background Technology

[0002] In the petrochemical industry, the risk control of water pollution has gained importance, and rainwater and wastewater separation technology has developed rapidly. Controlling initial rainwater runoff as polluted water is also a crucial aspect. With the rapid development of industrial technology, environmental requirements are becoming increasingly stringent. The main discharge outlets of stormwater pipes to the sea have gradually evolved from direct discharge to discharge based on monitored water quality. For industrial projects, initial rainwater polluted by industrial wastewater has also been included in the scope of water quality monitoring. Currently, in many projects, initial rainwater separation and water quality monitoring functions are fragmented and scattered throughout the plant area. Rainwater systems often only have moisture-proof wells at the terminal, and even some main control valves are missing. This not only fails to meet relevant regulations but also makes management inconvenient, and there is a lack of clear collection and treatment concepts for polluted rainwater. Therefore, a three-valve well discharge monitoring device is urgently needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a three-valve well discharge monitoring device to solve the problems mentioned in the background art.

[0016] 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.

[0017] In this embodiment of the utility model, please refer to Figures 1 to 3A three-valve well discharge monitoring device includes an inlet pipe 6, which is connected to the interior of a monitoring pool 1. One side of the monitoring pool 1 is connected to the interior of a valve well 2. An electric valve gate 2 12 is installed in the valve well 2. The valve well 2 is connected to a temporary storage pool via a connecting pipe. One side of the monitoring pool 1 is connected to the interior of a valve well 3. An electric valve gate 8 is installed in the valve well 3. One side of the valve well 3 is connected to the interior of a valve well 4. A duckbill valve 9 is installed in the valve well 4. One end of the valve well 4 is connected to an outlet pipe 10. The other end of the outlet pipe 10 is connected to the sea. Embossed steel cover plates 13 are installed on the top of the monitoring pool 1, valve well 2, valve well 3, and valve well 4. A water quality analyzer 7 is installed inside the monitoring pool 1. A collection pit 11 is installed inside the valve well 2, valve well 3, and valve well 4.

[0018] Water quality analyzer 7 tests the water quality inside monitoring tank 1. When the water quality is qualified and there is no tidal surge, electric valve gate 8 opens and electric valve gate 12 closes, allowing rainwater to be discharged into the sea normally. When the water quality is unqualified, electric valve gate 8 closes and electric valve gate 12 opens, diverting sewage to a temporary storage tank (not shown in the figure). When the water quality is qualified but there is a tidal surge, electric valve gate 8 closes, and rainwater is temporarily collected in the plant's pipe network, to be discharged into the sea normally after the tide recedes.

[0019] In this embodiment, the water quality analyzer 7 can be equipped with monitoring and analysis instruments such as COD analyzer, pH analyzer, and flow meter to monitor and transmit water quality remotely.

[0020] Electric valve gate 18 and electric valve gate 212 have three functions: automatic opening and closing based on water quality signal, remote manual opening and closing, and local manual opening and closing. Electric valve gate 18 is the main control valve for the rainwater discharge of the entire plant.

[0021] As one embodiment of this utility model, please refer to Figures 1 to 3 The monitoring pool 1, valve well 1 2, valve well 2 3 and valve well 3 4 are all equipped with ladders 5.

[0022] The ladder 5 facilitates staff access to the monitoring pool 1, valve well 1 2, valve well 2 3, and valve well 3 4 for maintenance.

[0023] As one embodiment of this utility model, please refer to Figure 1 Waterproof sleeves are provided at the connection between the monitoring pool 1 and the inlet pipe 6, and at the connection between the valve well 3 4 and the outlet pipe 10, to improve waterproof sealing and prevent rainwater leakage.

[0024] As one embodiment of this utility model, the monitoring pool 1, valve well 1 2, valve well 2 3 and valve well 3 4 are all made of C50 to C100 seawater corrosion resistant concrete.

[0025] As one embodiment of this utility model, the electric valve gate 8, the electric valve gate 12, the duckbill valve 9, and the water outlet pipe 10 are all coated with anti-corrosion paint that is resistant to seawater corrosion, so as to avoid their service life being affected by seawater erosion.

[0026] The working principle of this utility model is as follows: In standby mode, when it is not raining, the electric valve gate 8 in valve well 2 3 is in the closed state, and there is no water that can be discharged into the sea; the electric valve gate 12 in valve well 2 is in the open state, ready to receive the initial rainwater at any time.

[0027] In operation, during rainy days, initial rainwater enters monitoring pool 1 through the collection system, and water quality analyzer 7 begins to output monitoring data. Before the water quality data meets the standards, rainwater can only enter valve well 2 and is discharged to the initial rainwater storage pool built in the plant area through the opened electric valve gate 2 12. Once all water quality indicators in the monitoring pool meet the standards, electric valve gate 2 12 in valve well 2 will automatically close, and electric valve gate 8 in valve well 2 3 will automatically open. Later, clean rainwater is discharged into the sea through electric valve gate 8 and duckbill valve 9. After the rain ends, authorized personnel can remotely or locally close electric valve gate 8 and open electric valve gate 2 12 to restore the standby state.

[0028] In manual control mode, when there is a tidal surge in the sea area where the main rainwater discharge outlet is located, the electric valve gate 8 can be remotely or locally closed by the management personnel with the corresponding authority. The rainwater is temporarily collected in the plant area's pipeline network and discharged into the sea normally after the tide recedes.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
