Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage devices, in particular to an emergency cut-off valve control device for sudden environmental incidents at the main rainwater outlet of a factory area. Background Art
[0002] In case of leakage or discharge of decontamination polluted wastewater caused by sudden environmental incidents in the factory area, it is necessary to timely cut off the concrete water pipe to prevent the leaked liquid or polluted wastewater from flowing out of the factory area to avoid environmental water pollution. However, in rainy days, the concrete water pipe needs to be opened to avoid waterlogging. There are mainly two existing technologies. One is manual control. When the depth of the main rainwater outlet is within 1.5 meters, a butterfly valve, a gate valve or a sluice gate is used to control the opening and closing. In rainy days, the staff manually operates to open the valve or the sluice gate. When a sudden environmental incident occurs, sandbags and expansion air bags are used for blocking. The other is automatic control. The sensor controls the opening and closing of the valve through a hydraulic control system, realizing closing in sunny days and automatic opening in rainy days.
[0003] The existing manual control has the following problems. First, the staff cannot open and close in time in rainy and sunny days. Second, when a sudden environmental incident occurs, sandbags, expansion air bags, etc. are used for blocking. On the one hand, the operation reliability is poor. On the other hand, the blocking effect is not good. Third, once the total rainwater depth exceeds 3 meters, it is difficult to recover the sandbags or expansion air bags after the emergency.
[0004] The existing automatic control also has problems. The automatic control device sets a flap valve below the confluence of the branch pipes of the main rainwater outlet, and uses a rain sensor and a hydraulic control system to be linked with the control valve underground. On the one hand, the device is prone to failure due to the hydraulic drive motor getting water. On the other hand, there is a potential safety hazard of electric leakage of electrical equipment in a humid environment. Third, when the confluence depth of the rainwater branch pipes exceeds 4 meters, the automatic control device cannot be popularized and implemented due to high construction difficulty and high cost, and can only be forced to use primitive methods such as sandbags and expansion air bags for blocking. It is difficult to recover the sandbags or expansion air bags after the emergency.
[0005] Therefore, the applicant intends to propose an emergency cut-off valve control device for sudden environmental incidents at the main rainwater outlet of a factory area to solve the above problems. Summary of the Utility Model
[0006] The purpose of the utility model is to provide an emergency cut-off valve control device for sudden environmental incidents at the main rainwater outlet of a factory area.

[0030] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to the provided drawings.
[0031] An emergency cut-off valve control device for the total rainwater outlet 7 in a factory area, comprising a rainwater total outlet 7 and a concrete water pipe 8. The rainwater total outlet 7 is located on the ground surface and is used for collecting rainwater. The concrete water pipe 8 is arranged underground and is connected to the rainwater total outlet 7. The concrete water pipe 8 is used for guiding the rainwater collected by the rainwater outlet. It also includes a sensor 1, an electrical control device 2, a manual-electric integrated turbine box 3, a transmission device 4, a stainless steel knife gate valve 5, and a liquid level alarm 6. The sensor 1 is used to identify rainy days and sunny days. The sensor 1 receives the rainwater and generates an electrical signal change. The sensor 1 is set on the ground surface and is electrically connected to the electrical control device 2. The sensor 1 is used to transmit an electrical signal to the electrical control device 2. The electrical control device 2 is set on the ground surface, away from the rainwater in the rainwater total outlet 7 and the concrete water pipe 8, not easily affected by moisture, avoiding the safety hazard of electric leakage. The electrical control device 2 is electrically connected to the manual-electric integrated turbine box 3. The electrical control device 2 is used to transmit an electrical signal to the manual-electric integrated turbine box 3. The manual-electric integrated turbine box 3 includes an electric input end 31, a manual input end 32, and an output end 33. The electric input end 31 is electrically connected to the electrical control device 2. The manual input end 32 is used for the staff to manually start the manual-electric integrated turbine box 3. The output end 33 is in transmission connection with the transmission device 4. The transmission device 4 is in transmission connection with the stainless steel knife gate valve 5. The output end 33 controls the opening and closing of the stainless steel knife gate valve 5 through the transmission device 4. The stainless steel knife gate valve 5 is arranged in the concrete water pipe 8. When the stainless steel knife gate valve 5 is opened, the concrete water pipe 8 discharges rainwater. When the stainless steel knife gate valve 5 is closed, the concrete water pipe 8 blocks the discharge of rainwater. The liquid level alarm 6 is arranged at the rainwater total outlet 7.
[0032] In order to avoid leakage or the discharge of wastewater from decontamination pollution, the stainless steel knife gate valve 5 is generally in a closed state.
[0033] During normal operation, the electrical control device 2 is in an automatic control state. When the sensor 1 identifies a rainy day, the sensor 1 outputs a start signal to the electrical control device 2. The electrical control device 2 outputs a start signal to the electric input end 31 of the manual-electric integrated turbine box 3. The output end 33 of the manual-electric integrated turbine box 3 outputs a start signal to the transmission device 4. The transmission device 4 drives the stainless steel knife gate valve 5 to open, and the concrete water pipe 8 discharges rainwater. When the sensor 1 identifies a sunny day, the sensor 1 outputs a close signal to the electrical control device 2. The electrical control device 2 outputs a close signal to the electric input end 31 of the manual-electric integrated turbine box 3. The output end 33 of the manual-electric integrated turbine box 3 outputs a close signal to the transmission device 4. The transmission device 4 drives the stainless steel knife gate valve 5 to close, and the concrete water pipe 8 blocks the discharge of rainwater.
[0034] In extreme cases, when a rainstorm causes damage to the circuit and the device loses power supply, the electrical control device 2 stops operating. Rainwater continuously flows into the main rain inlet 7 and accumulates in the concrete water pipe 8. When the rainwater level rises to the main rain inlet 7, the liquid level alarm 6 is triggered. After hearing the alarm, the staff go to the device and operate the manual input end 32 of the manual-electric integrated turbine box 3, causing the output end 33 of the manual-electric integrated turbine box 3 to start outputting. The transmission device 4 drives the stainless steel knife gate valve 5 to open, and the concrete water pipe 8 discharges the rainwater. As the rainwater is discharged and the water level drops, the liquid level alarm 6 stops alarming.
[0035] In other cases, the device operates normally, but it is necessary to open the concrete water pipe 8. The staff operate the electrical control device 2 to be in the manual control state, and then operate the manual input end 32 of the manual-electric integrated turbine box 3, causing the output end 33 of the manual-electric integrated turbine box 3 to start outputting. The transmission device 4 drives the stainless steel knife gate valve 5 to open, thus opening the concrete water pipe 8.
[0036] The manual input end 32 and the output end 33 of the manual-electric integrated turbine box 3 are mechanically linked. Even without power supply, the staff can still control the transmission device 4 through the manual-electric integrated turbine box 3. The liquid level alarm 6 is an alarm that does not require external direct current or alternating current, such as a float liquid level gauge combined with a sound element, ensuring that the staff can still be reminded to go to the site for confirmation and handling even in the case of power failure.
[0037] It also includes an operation room 9, which is set on the ground and covers the electrical control device 2 and the manual-electric integrated turbine box 3. The operation room 9 isolates rainwater and extends the service life of the electrical control device 2 and the manual-electric integrated turbine box 3.
[0038] The sensor 1 is electrically connected to the electrical control device 2 through a wire 11. An opening 91 is provided at the top of the operation room 9. One end of the wire 11 is connected to the sensor 1, and the other end of the wire 11 extends into the opening 91 and is connected to the electrical control device 2. A protective tube 12 is sleeved outside the wire 11. The sensor 1 is installed outside the operation room 9 to ensure that the sensor 1 can fully receive rainwater and then send an accurate electrical signal.
[0039] The protective tube 12 is made of stainless steel pipe, which is a rigid pipe. It can support the sensor 1 on the top of the operation room 9 so that the sensor 1 can fully contact the rainwater. In addition, the stainless steel pipe can resist rainwater erosion and protect the wire 11.
[0040] The transmission device 4 includes a flexible transmission shaft 41 and a sleeve 42. One end of the flexible transmission shaft 41 is in transmission connection with the output end 33, and the other end of the flexible transmission shaft 41 is in transmission connection with the stainless steel knife gate valve 5. The sleeve 42 is sleeved outside the flexible transmission shaft 41. The transmission device 4 needs to connect the manual-electric integrated turbine box 3 located on the ground surface and the stainless steel knife gate valve 5 located underground. Its path may need to bypass surface facilities or underground facilities. Therefore, the flexible transmission shaft 41 is used. A part of the flexible transmission shaft 41 is located underground and is easily eroded by the soil. The sleeve 42 is sleeved outside the flexible transmission shaft 41 to extend the service life of the transmission device 4.
[0041] The sleeve 42 is made of stainless steel pipe. The stainless steel pipe has good corrosion resistance and can effectively prevent the corrosion of the sleeve 42 by groundwater, soil and chemical substances. Especially the 304 and 316L stainless steel materials can resist the erosion of corrosive substances such as chloride ions. In addition, the tensile strength of the stainless steel pipe is much higher than that of ordinary steel pipes and copper pipes, and it can withstand greater external forces and pressures to ensure the stability and safety of the device.
[0042] The manual input end 32 adopts a control handwheel. The staff rotates the control handwheel to make the output end 33 of the manual-electric integrated turbine box 3 output.
[0043] In the description of the present utility model, when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be intermediate components present at the same time.
[0044] The above is only the preferred embodiment of the present utility model and does not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
