[0014] A high temperature rainy season highway construction drainage process, comprising the following steps: S1: In the hot rainy season, there is serious water accumulation at the highway construction site. The drainage equipment starts to work. It consists of a submersible pump, a drive device, etc. The motor of the drive device runs and drives the submersible pump after adjustment by the reduction gear box. The impeller rotates at high speed in the pump casing, generating centrifugal force to suck the accumulated water from the filter. The filter prevents foreign matter from damaging the pump body. The water is pressurized and discharged through the drain pipe to lower the water level. When the forward and reverse switching mechanism is in the working position, the motor power is transmitted in turn to drive the impeller to rotate forward to drain water. The connection of each component is stable to ensure operation; S2: Due to the accumulation of impurities, the submersible pump is easily blocked, resulting in a decrease in drainage efficiency. The PLC programmable controller presets the standard values ​​of water flow and pressure, and the sensor monitors and transmits data in real time. When the flow of the drainage pipe is lower than the preset 20%, it is determined to be blocked. At this time, the drainage pipe is connected to the water source, the PLC controls the electric cylinder to shrink, the rotating rod moves down, the impeller enters the filter, and the equipment enters the backwash position. When the pressure exceeds 15%, the PLC programmable controller adjusts the parameters or controls the valve; S3: In the backwash position, the impeller reverses and drives the auger to rotate through the transmission to clean the filter surface. After that, the flow control unit works, the PLC opens the electric booster valve, and water flows into the sprinkler head through the pipeline. When the pressure exceeds the limit, the safety valve releases the pressure, the pressure reducing valve adjusts the pressure, the flow control valve adjusts the flow, the filter shell filter protects the valve, and the sprinkler head flushes in all directions. When the pressure is abnormal, the alarm sounds, the backwash is completed, the flow is restored, and the equipment returns to the working position to continue draining.

[0015] The beneficial effects of the present invention are: 1. When the present invention is in use, the forward and reverse switching mechanism, which is composed of a rotating rod, a transmission rod, and a bevel gear, enables the submersible pump to have flexible drainage and backwashing functions. During normal drainage, the electric cylinder pushes the rotating rod to move upward, the lower bevel gear meshes with the driving bevel gear, and the impeller rotates forward to drain. When blockage occurs, the rotating rod moves downward, the upper bevel gear meshes with the driving bevel gear, and the impeller reverses to achieve backwashing. At the same time, the auger connected to the impeller rotates to clean the outer wall of the filter, thereby enhancing the backwashing effect and ensuring the continuous and stable operation of the equipment. 2. When the present invention is in use, the flow control unit, the transmission device and the pressure sensing component work together to effectively deal with the blockage problem of the submersible pump. When blockage occurs, the water flow sensor monitors the pressure and flow rate changes in the drain pipe in real time, triggers the transmission device to switch to the backwash position, the impeller reverses, and the water in the drain pipe is sprayed out from the sprinkler head through the external branch pipe, the annular pipe and the hose to flush the pump casing and the filter. At the same time, the water is discharged from the water inlet of the submersible pump to achieve backwashing. In the flow control unit, the electric boost valve enhances the water spraying pressure and cooperates with the electric pressure reducing valve to stabilize the system pressure. The flow control valve is used to adjust the flow and the spring-type safety valve is used to ensure safety. If the internal pressure of the drain pipe does not meet the standard after backwashing, it will switch to the backwash position again until the pressure meets the standard and the submersible pump resumes normal drainage, thereby improving the equipment reliability and blockage clearing efficiency.

A cylindrical filter 12 is connected, and the filter 12 prevents foreign matter from entering the pump casing 30 when the submersible pump 13 absorbs water. The top of the pump casing 30 is fixedly connected with a connecting pipe 28, and the upper surface of the connecting pipe 28 is fixedly connected with a transmission pipe 6. The top of the transmission pipe 6 is fixedly connected to a driving device, and the transmission device is located in the transmission pipe 6. The outer surface of the transmission pipe 6 is fixedly connected with a fixing platform 4, and the upper surface of the fixing platform 4 is fixedly connected with a fixing frame 19. The outer surface of the drain pipe 22 is fixedly connected with two fixing plates 18, and the inner wall of each fixing plate 18 is threadedly connected with a fixing bolt 17 together with the inner wall of the fixing frame 19.

[0020] In this embodiment, in the hot rainy season, a large amount of water is easily formed at the highway construction site. The drainage equipment of this embodiment includes a submersible pump 13, a driving device, a transmission device, a drainage pipe 22, a flushing device and a flow control unit. After the driving device is started, the submersible pump 13 is driven by the transmission device to operate. In the pump casing 30 of the submersible pump 13, the impeller 39 rotates coaxially at high speed to generate a strong centrifugal force to suck the surrounding accumulated water from the cylindrical filter 12 at the water inlet end. In the hot rainy season, the accumulated water is often mixed with a large amount of foreign matter such as branches, leaves and mud. The filter 12 can effectively prevent these foreign matter from entering the pump casing 30 to avoid damage to the impeller 39 and the pump body, thereby ensuring the normal operation of the submersible pump 13. After the water is pressurized by the impeller 39, it is sucked from the water inlet end. The output end of the pump casing 30 enters the drain pipe 22 and is discharged to a suitable drainage area, such as a rainwater pipe network or a low-lying drainage area, thereby quickly lowering the water level at the construction site and reducing the impact of accumulated water on the construction progress and safety. The flushing device on the outside of the drain pipe 22 and the flow control unit on its outside can cope with possible blockages of the submersible pump 13. The connecting pipe 28 at the top of the pump casing 30 is connected to the transmission pipe 6, and the top of the transmission pipe 6 is fixedly connected to the driving device. The fixing frame 19 on the fixing platform 4 on the outer surface of the transmission pipe 6 is firmly connected to the fixing plate 18 on the outer surface of the drain pipe 22 through the fixing bolts 17, ensuring that the various components of the equipment can work stably together in a high temperature and humid environment to ensure continuous and efficient drainage work.

[0021] Embodiment 2, on the basis of embodiment 1, as Figure 1-6As shown, the transmission device includes a forward and reverse switching mechanism, the output end of which drives the impeller 39 to rotate forward or reversely, the forward mode is the working position of the transmission device, and the reverse mode is the backwashing position of the transmission device. The forward and reverse switching mechanism includes a rotating rod 38 fixedly arranged on the top end of the rotating shaft of the impeller 39, the top end of the rotating rod 38 is fixedly connected to the transmission rod 25, and the outer surface and the top end of the transmission rod 25 are respectively fixedly connected to the lower bevel gear 31 and the upper bevel gear 33.

[0022] In this embodiment, the forward and reverse switching mechanism includes a rotating rod 38, a transmission rod 25, a lower bevel gear 31 and an upper bevel gear 33. In the normal drainage stage, the transmission device is in the working position, the forward and reverse switching mechanism drives the impeller 39 to rotate forward, and the submersible pump 13 efficiently sucks and discharges the accumulated water at the highway construction site. However, in the hot rainy season, the accumulated water contains more impurities. After the submersible pump 13 has been running for a long time, the filter 12 and the pump housing 30 are easily blocked by mud, sand, and debris, resulting in a decrease in drainage efficiency. The flow standard value of the water flow sensor 20 is pre-set through the PLC programmable controller 24. In normal drainage, During the process, the water flow sensor 20 monitors the water flow in the drain pipe 22 in real time and transmits the data to the PLC programmable controller 24. When the internal flow of the drain pipe 22 is lower than 20% of the preset standard value, the PLC programmable controller 24 determines that the submersible pump 13 is blocked, and then controls the forward and reverse switching mechanism to reverse the impeller 39 and enter the backwash position. By changing the rotation direction of the impeller 39, the suction and discharge direction of the submersible pump 13 is reversed, preparing for the subsequent removal of the blockage, so that the equipment can respond to the blockage problem in time without disassembly, thereby improving the adaptability and reliability of the equipment in complex environments.

[0023] Embodiment 3, on the basis of embodiment 2, as Figure 1-6 As shown, the driving device includes a motor 2 and a reduction gear box 1, the motor 2 is fixedly connected to the reduction gear box 1, the output shaft of the motor 2 is fixedly connected to the input shaft of the reduction gear box 1, the output shaft of the reduction gear box 1 is fixedly connected to the driving bevel gear 32, and the transmission rod 25 moves upward so that the lower bevel gear 31 and the driving bevel gear 32 are meshed to form the working position of the transmission device.

[0024] In this embodiment, the driving device includes a motor 2 and a reduction gear box 1, which provide stable power for the equipment during drainage in the hot rainy season. The motor 2, as a power source, continues to operate in a hot and humid environment to provide power for drainage work. The reduction gear box 1 adjusts the high speed output by the motor 2, outputs appropriate torque and speed, and ensures that the submersible pump 13 can work stably and efficiently. When in the working position, the output shaft of the reduction gear box 1 drives the driving bevel gear 32 to rotate. When the transmission rod 25 moves upward, the lower bevel gear 31 is meshed with the driving bevel gear 32. The power of the motor 2 is transmitted to the transmission rod 25 and the rotating rod 38 through the reduction gear box 1, the driving bevel gear 32, and the lower bevel gear 31 in turn, and finally drives the impeller 39 to rotate forward. At this time, the submersible pump 1 3 Normal drainage, quickly drain the accumulated water at the highway construction site to ensure the dryness and safety of the construction site. At the same time, the PLC programmable controller 24 also pre-sets the pressure standard value range of the capacitive pressure sensor 7. Under normal working conditions, the capacitive pressure sensor 7 monitors the system pressure in real time and transmits the data to the PLC programmable controller 24. When the pressure exceeds 15% of the standard value range, for example, the pressure is too high, which may be due to pipe blockage or booster valve failure, and the pressure is too low, which may be due to pump failure or pipe leakage. The PLC programmable controller 24 can adjust the operating parameters of the drive device according to the specific situation, or control the relevant valve action to ensure that the equipment operates within a safe pressure range, ensuring the stable operation of the equipment in the harsh environment of high temperature and rainy season.

[0026] In this embodiment, the telescopic action of the electric cylinder 36 is precisely controlled by the PLC programmable controller 24, and the up and down movement of the rotating rod 38 can be flexibly controlled according to the actual drainage situation and the blockage detection result. In a hot and humid environment, the equipment may malfunction due to factors such as moisture, and this electric control method can respond quickly and adjust the equipment status in time. When the telescopic end of the electric cylinder 36 is extended, the stabilizing ring 34 is pushed to slide along the inside of the transmission tube 6, thereby driving the rotating rod 38 to move up, so that the lower bevel gear 31 is meshed with the driving bevel gear 32, and the equipment enters the working position and drains normally.

When the system pressure is abnormal, such as exceeding or falling below the preset pressure standard value or other faults occur, an alarm is issued in time to remind the staff to deal with it. When the backwashing is completed and the water flow sensor 20 monitors that the flow in the drain pipe 22 has returned to near the preset standard value, the PLC programmable controller 24 controls the equipment to return to the working position and continue to drain water through the drain pipe 22.

[0029] Working principle: In the hot and rainy season, a large amount of water is very likely to accumulate at the highway construction site. This drainage equipment can solve this problem very well. The equipment is mainly composed of a submersible pump 13, a drive device, a transmission device, a drain pipe 22, a flushing device and a flow control unit. The motor 2 in the drive device continues to operate stably in a hot and humid environment to provide power for the entire equipment. The reduction gearbox 1 adjusts the high speed output by the motor 2 and outputs appropriate torque and speed to ensure that the submersible pump 13 can work stably and efficiently. After the drive device is started, the submersible pump 13 is driven by the transmission device. In the pump casing 30 of the submersible pump 13, the impeller 39 rotates coaxially at high speed. The pump 13 is pumped in a pump housing 30 and pumped in by a pump 22. The pump housing 30 ... A fixing frame 19 is installed on the fixing platform 4 on the outer surface of the transmission pipe 6. The fixing frame 19 is firmly connected to the fixing plate 18 on the outer surface of the drainage pipe 22 by fixing bolts 17, ensuring that the various components of the equipment can work stably together in a hot and humid environment to ensure that the drainage work is carried out continuously and efficiently. The forward and reverse switching mechanism is composed of a rotating rod 38, a transmission rod 25, a lower bevel gear 31 and an upper bevel gear 33. In the normal drainage stage, the transmission device is in the working position, and the output shaft of the reduction gear box 1 drives the driving bevel gear 32 to rotate. When the transmission rod 25 moves upward, the lower bevel gear 31 is meshed with the driving bevel gear 32, and the power of the motor 2 is sequentially transmitted through the reduction gear box 1. The driving bevel gear 32 and the lower bevel gear 31 are transmitted to the transmission rod 25 and the rotating rod 38, and finally the impeller 39 is driven to rotate forward, and the submersible pump 13 is normally drained through the drain pipe 22. However, due to the high temperature rainy season, the water contains more impurities. After the submersible pump 13 has been running for a long time, the filter 12 and the pump housing 30 are easily blocked by mud, sand, and debris, resulting in a decrease in drainage efficiency. The PLC programmable controller 24 pre-sets the flow standard value of the water flow sensor 20 and the pressure standard value range of the capacitive pressure sensor 7. In the normal drainage process, the water flow sensor 20 monitors the water flow in the drain pipe 22 in real time and transmits the data to the PLC programmable controller 24;The capacitive pressure sensor 7 monitors the system pressure in real time and also transmits the data to the PLC programmable controller 24. When the internal flow of the drain pipe 22 is lower than 20% of the preset standard value, it can be adjusted according to actual needs. The PLC programmable controller 24 determines that the submersible pump 13 is blocked. At this time, the drain pipe 22 needs to be placed in a low-lying area with water to ensure that there is sufficient water for backwashing and prevent the backwashing operation from being unable to be completed due to insufficient water. Subsequently, the PLC programmable controller 24 controls the electric cylinder 36 to contract and the rotating rod 38 to move downward, so that the upper bevel gear 33 is engaged with the driving bevel gear 32. At the same time, the impeller 39 is separated from the pump housing 30 and enters the filter 12. The equipment enters the backwashing position. If the pressure exceeds the standard value range by 15%, the PLC programmable controller 24 will adjust the operating parameters of the drive device according to the specific situation, or control the relevant valve action to ensure that the equipment operates within a safe pressure range. After entering the backwashing position, the impeller 39 reverses and drives the first clutch 21 to move downward through the lower shaft 49, so that the first clutch 21 and The second clutch 54 is engaged, and the rotation of the first clutch 21 and the second clutch 54 drives the linkage shaft 53 to rotate inside the second bearing 52, and then drives the auger piece 29 to rotate through the linkage shaft 53 and the radial rod 40. The auger piece 29 is connected to the third bearing 50 through the connecting shaft 48, which ensures the stability of the rotation of the auger piece 29 and enhances the backwashing effect. The auger piece 29 is adapted to the outer wall of the filter 12, and the surface of the filter 12 is spirally cleaned, and the larger garbage, mud and other impurities attached to the surface of the filter 12 are preliminarily removed to complete the auger. After the dragon sheet 29 cleans the garbage on the surface of the filter 12, the flow control unit starts to work, and the PLC programmable controller 24 controls the electric booster valve 27 to open, increasing the water pressure in the outer branch pipe 26. The water enters the annular pipe 8 through the outer branch pipe 26 and then flows into the sprinkler head 47 through the hose 9. The capacitive pressure sensor 7 on the outer surface of the outer branch pipe 26 monitors the system pressure in real time and transmits the data to the PLC programmable controller 24. When the pressure exceeds 15% of the preset standard value, the spring-loaded safety valve 16 automatically opens to release the pressure to protect the safety of the equipment.The electric pressure reducing valve 15 automatically adjusts the pressure according to the pressure conditions to ensure that the system pressure is stable within the standard range. The flow control valve 14 accurately adjusts the water flow rate according to the needs of backwashing, so that the water spray head 47 can rinse the surface of the filter 12 with appropriate pressure and flow rate to further remove the remaining fine impurities. When the motor 2 drives the impeller 39 to reverse, a small amount of water can also be drawn into the drain pipe 22. The entrance of the drain pipe 22 is located in a low-lying area with water to ensure that there is sufficient water supply inside the drain pipe 22. The first filter screen 42, the second filter screen 43 and the third filter screen 44 are installed in the filter shell 5 on the outer surface of the outer branch pipe 26, which can perform multi-stage filtration on the water flow, not only preventing impurities from entering the water spray head 47 again, but also protecting the spring-loaded safety valve 16, the electric pressure reducing valve 15, and the flow control valve 14. The valves 14 and the electric booster valve 27 are prevented from being blocked by impurities and affecting their normal operation. The limit plate 45 and the stabilizing shaft 46 in the inner wall of the fixed ring 11 fixed shell 10 enable the water spray head 47 to rotate flexibly, and the filter 12 is flushed in all directions to completely flush away the blockage. The pressure alarm 23 on the upper surface of the reduction gear box 1 is connected to the PLC programmable controller 24. When the system pressure is abnormal, such as exceeding or falling below the preset pressure standard value, or other faults occur, the pressure alarm 23 will promptly sound an alarm to remind the staff to handle it. When the backwashing is completed and the water flow sensor 20 detects that the flow in the drain pipe 22 has returned to the preset standard value, the PLC programmable controller 24 controls the equipment to return to the working position and continue to drain water through the drain pipe 22. ;

[0030] In combination with the above process, this scheme provides a high temperature rainy season highway construction drainage process, which specifically includes the following steps: S1: In the hot rainy season, the highway construction site is seriously flooded. The drainage equipment starts to work. It consists of a submersible pump 13, a driving device, etc. The motor 2 of the driving device runs, and drives the submersible pump 13 after being adjusted by the reduction gear box 1. The impeller 39 rotates at high speed in the pump housing 30, generating centrifugal force to suck the accumulated water from the filter 12. The filter 12 prevents foreign matter from damaging the pump body. The water is pressurized and discharged through the drain pipe 22 to lower the water level. When the forward and reverse switching mechanism is in the working position, the motor power is transmitted in turn to drive the impeller 39 to rotate forward to drain water. The connection of each component is stable to ensure operation; S2: Due to the accumulation of impurities, the submersible pump 13 is easily blocked, resulting in a decrease in drainage efficiency. The PLC programmable controller 24 presets the standard values ​​of water flow and pressure, and the sensor monitors and transmits data in real time. When the flow of the drain pipe 22 is lower than the preset 20%, it is determined to be blocked. At this time, the drain pipe is connected to the water source, the PLC controls the electric cylinder 36 to contract, the rotating rod 38 moves downward, the impeller 39 enters the filter 12, and the equipment enters the backwash position. When the pressure exceeds 15%, the PLC programmable controller 24 adjusts the parameters or controls the valve; S3: In the backwash position, the impeller 39 reverses and drives the auger piece 29 to rotate and clean the surface of the filter 12 through the transmission. After that, the flow control unit works, the PLC opens the electric booster valve 27, and water flows into the sprinkler head 47 through the pipeline. When the pressure exceeds the limit, the safety valve 16 releases the pressure, the pressure reducing valve 15 adjusts the pressure, the flow control valve 14 adjusts the flow, the filter housing 5 filter screen protects the valve, and the sprinkler head 47 flushes in all directions. When the pressure is abnormal, the alarm 23 sounds an alarm, the backwash is completed, the flow is restored, and the equipment returns to the working position to continue draining.
