Description

Technical Field

[0001] The present invention relates to the field of bridge deck runoff discharge, and particularly to a bridge deck runoff classification liquid discharge system based on intelligent detection and control technology. Background Art

[0002] With the rapid development of China's economy, large bridges, elevated highways, etc. in cities have been built one after another, which not only facilitates vehicle travel, but also alleviates traffic pressure and solves problems of congestion and jams. Generally, a drainage system is installed on the large bridge to meet the problem of runoff discharge in rainy days and avoid water flow blockage on the bridge and highway. However, there are more and more vehicles transporting dangerous chemicals on the bridge and highway. During the transportation of dangerous goods, leakage accidents are inevitable. Once liquid chemicals leak, they will flow to the ground under the bridge or into the river along the drainage system of the bridge, thereby polluting the ground or the aquatic resource environment, and seriously causing an ecological disaster.

[0003] In the current bridge deck drainage system, no runoff control device is installed or taken, and only a single pipe is used for liquid discharge. Therefore, rainwater and chemical liquids cannot be well distinguished, discharged and controlled, and it is easy to cause leakage of dangerous chemicals, resulting in water resource and land pollution. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, avoid the inability to classify the discharge of liquids in the bridge deck drainage system, and cause ecological environmental pollution, and provide a bridge deck runoff classification liquid discharge system based on intelligent detection and control technology. By combining intelligent detection of water quality and the discharge system, the present invention can reasonably classify and control the liquids on the bridge deck, so as to achieve the purpose of protecting water resources, protected areas and the environment.

[0005] The purpose of the present invention is achieved by the following measures: A bridge deck runoff classification liquid discharge system based on intelligent detection and control technology includes not less than two groups of drain pipes horizontally arranged at the bottom of the bridge deck and communicating with the bridge deck. Both ends of the drain pipe are in a closed state. One drainage branch pipe is distributed on each group of drain pipes, and the drainage branch pipe is connected with a detection and control device for controlling whether the liquid flows; A sewage pipe for discharging dangerous chemicals is also arranged in parallel outside the drain pipe. A connecting member for controlling the discharge of dangerous chemicals into the sewage pipe is connected between the sewage pipe and above each group of drain pipes. Not less than two sewage branch pipes are also connected to the sewage pipe, and the tail ends of the sewage branch pipes lead to an emergency collection pool or an emergency collection tank.

[0006] Preferably, the detection and control device includes a valve pipe. The left end of the valve pipe is a liquid inlet, which is connected with the drainage branch pipe. The bottom of the valve pipe is provided with a liquid outlet, and a liquid discharge pipe is connected to the liquid outlet. A valve core capable of reciprocating to block the liquid outlet is arranged at the right end of the valve pipe; A control system for controlling the movement of the valve core is also arranged on the valve pipe;

[0007] The control system includes a data processing module and a control module arranged on the right side of the valve core. A water quality sensor is arranged at the liquid inlet. The water quality sensor, the data processing module, and the control module are communicatively connected in sequence. A power module for driving the movement of the valve core is further arranged at the right end of the valve core, and the power module is connected to the control module.

[0008] Preferably, the connecting member is an inverted U-shaped pipe, and the U-shaped pipe is connected above the sewage pipe and the drain pipe.

[0009] Preferably, a temperature sensor and a heating device are arranged on the valve core, and the heating device is a heating ring arranged on the valve core.

[0010] Preferably, a sealing ring is further arranged on the valve core.

[0011] Preferably, a liquid level sensor is further arranged at the liquid inlet, and the liquid level sensor is connected to the control module.

[0012] Preferably, the power module is an electric device, a cylinder, or a hydraulic cylinder.

[0013] Preferably, an exhaust hole is further arranged at the bottom of the rightmost end of the valve pipe.

[0014] The beneficial effects of the present invention are as follows: The structure of the present invention is reasonable and environmentally friendly. By detecting the distribution of the control device and the drain pipe and the sewage pipe, the liquid on the bridge deck can be classified and discharged and controlled reasonably. The liquid on the bridge deck will flow into each group of drain pipes according to the principle of proximity, and each group of drain pipes is not connected and does not affect each other. The detection and control device on each group of drain pipes will detect the water quality. If it is rainwater without pollution, it will be discharged through the liquid outlet and the liquid discharge pipe to the water channel on the ground. If it is detected as a dangerous chemical liquid, the detection and control device will block the liquid outlet. At this time, the water in the drain pipe will accumulate more and more, and finally overflow to the sewage pipe through the inverted U-shaped pipe and be discharged to the emergency collection pool through the sewage branch pipe.

[0015] If there is chemical liquid at a certain place on the bridge deck, it will flow into the nearest drain pipe for detection and reasonable discharge measures will be taken. The other groups of drain pipes will not be affected. At the same time, the separation of multiple groups of drain pipes is also helpful for drainage or exhaust, will not accumulate, and will not cause blockage of the bridge deck. This set of liquid discharge system is both environmentally friendly and practical, and is beneficial to maintaining the balance of the ecological environment. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: As Figure 1 , Figure 2 , Figure 3As shown in the figure, a bridge deck runoff classification drainage system based on intelligent detection and control technology includes no less than two groups of drain pipes 16 horizontally installed at the bottom of the bridge deck and connected to the bridge deck 15. That is, there are many drainage outlets on the bridge deck connected to the drain pipes. Liquids flow into each group of drain pipes 16 through the drainage outlets on the bridge deck according to the principle of proximity. The specific number of groups of drain pipes can be reasonably designed according to the length of the bridge deck. The length of each group of drain pipes is about 30 meters. The two ends of the drain pipes are in a closed state and are blocked by plugs. One drainage branch pipe 17 is evenly distributed on each group of drain pipes. A detection and control device for controlling whether the liquid is drained is connected to the drainage branch pipe. That is, the detection and control device is used to detect whether the water quality is a dangerous chemical. If it is a dangerous chemical, the detection and control device will take control measures. A sewage discharge pipe 18 for discharging dangerous chemicals is also installed in parallel outside the drain pipe. A connecting part for controlling the discharge of dangerous chemicals to the sewage discharge pipe is connected between the sewage discharge pipe 18 and the upper part of the drain pipe 16. That is, after the detection and control device detects the chemical, the detection and control device will control the liquid to be discharged into the sewage discharge pipe through the connecting part. The connecting part in this embodiment is an inverted U-shaped pipe, and the U-shaped pipe is connected above the sewage discharge pipe and the drain pipe; the connecting part can also be a straight pipe connecting the sewage discharge pipe and the drain pipe, and a solenoid valve for controlling the cut-off is installed on the straight pipe. No less than two sewage branch pipes 19 are also connected to the sewage discharge pipe. The tail ends of the sewage branch pipes lead to the emergency collection pool 22 or the emergency collection tank. When the detection and control device prevents the polluted liquid from being discharged to the ground, the liquid in the drain pipe 16 will accumulate more and more, and finally overflow into the sewage discharge pipe 18 through the inverted U-shaped pipe 20, and then be discharged into the emergency collection pool 22 or the collection tank through the sewage branch pipe 19 for reasonable discharge. The installation of the double pipes (drain pipes and sewage discharge pipes) can meet the engineering requirements, ensure both drainage and driving safety, and also meet the discharge conditions in rainy weather. Moreover, the drain pipes are in multiple groups and each group does not affect each other. When a chemical leak occurs at a certain place on the bridge deck, it will flow into the nearest drain, and the other drain pipes will work normally, so as to achieve the purpose of "grouping and zoning" control of the initial runoff with more dangerous chemical leaks or pollutants on the bridge deck.

[0022] The detection and control device includes a valve pipe 1. The left end of the valve pipe is a liquid inlet 2, and the liquid inlet 2 is connected to the drainage branch pipe. That is, the liquid passing through the drain pipe enters the valve pipe from the liquid inlet. An outlet 3 is provided at the bottom of the valve pipe, and a liquid discharge pipe 21 is connected to the outlet 3. That is, the liquid flowing through the valve pipe can flow out from the outlet and be discharged to the ground or the water channel through the liquid discharge pipe 21. A valve core 4 that can move back and forth to block the outlet is installed at the right end of the valve pipe 1. A control system for controlling the movement of the valve core is also installed on the valve pipe 1. The valve core 4 can move back and forth through control to block the outlet 3, thereby controlling whether the liquid is discharged from the outlet 3.

[0023] The control system includes a data processing module 6 and a control module 7 installed on the right side of the valve core. A water quality sensor 8 is also installed at the liquid inlet. The water quality sensor 8, the data processing module 6, and the control module 7 are communicatively connected in sequence. A power module 9 for driving the movement of the valve core is also installed at the right end of the valve core 4. The power module is connected to the control module. The water quality sensor is used to detect the degree of water pollution and distinguish the types of water. The data of the water quality sensor is sent to the data processing module. The data processing module processes the received information and transmits it to the control module. The control module conducts control and sends instructions. If the processed data shows that the water quality is polluted or a dangerous chemical, the control module sends an instruction to the power module to drive the valve core 4 to move, block the liquid outlet, and prevent the liquid from flowing out of the liquid outlet. It blocks at the liquid inlet, enabling the drainage system to take the next discharge measure. In this embodiment, the power module is an electric device. In addition, it can also be other power structures, such as a cylinder or a hydraulic cylinder, etc., as long as it can drive the valve core to move. If the water detected by the water quality sensor is rainwater or non-polluted liquid, the valve core will not block the liquid outlet 3, and the liquid will be normally discharged through the liquid discharge pipe 21. In this embodiment, the water quality sensor adopts any one or a combination of a dielectric constant sensor, a microwave sensor, a conductivity sensor, a PH sensor, a density sensor, a terahertz wave sensor, etc. to achieve the detection and analysis function of water pollution or dangerous chemicals in the present invention. Its specific structure and working principle will not be elaborated here. A heat dissipation device 5 is also installed on the right side of the valve core for assisting the heat dissipation function.

[0024] A temperature sensor 10 and a heating device are also installed on the valve core. The heating device is a heating ring 11 installed on the valve core. The real-time temperature inside the valve tube is measured by the temperature sensor. According to the need of the ambient temperature, the heating ring 11 conducts heating when the temperature is below 0°C to prevent situations such as incorrect monitoring by the sensor and icing of the valve core. A sealing ring 12 is also installed on the valve core 4 to prevent liquid leakage caused by the reciprocating movement of the valve core. Moreover, an exhaust hole 14 is opened at the bottom of the rightmost end of the valve tube. This exhaust hole is used to discharge the gas in the cavity when the valve core retracts backward. In addition, a small amount of infiltrated liquid can also be discharged through the exhaust hole. A liquid level sensor is also installed at the liquid inlet. The liquid level sensor is connected to the control module. Through the liquid level sensor, the "water level" situation in the pipeline can be known, thereby obtaining the water accumulation situation on the bridge and taking measures.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
