Multi-pump cooperative drainage operation platform

Abstract

This utility model provides a multi-pump collaborative drainage operation platform, including a drainage operation platform with several outward-facing lifting grooves on its side. A lifting wheel is rotatably mounted between the two walls of each lifting groove, and a lifting belt of a certain length is fixedly connected to the outer end face of the lifting wheel. Several submersible pumps are located below the drainage operation platform. This solution uses a lifting assembly to drive the lifting wheel, causing the submersible pumps to rise and fall vertically along the lifting grooves. This ensures that the submersible pump's pumping hole remains below the water surface and away from the bottom sediment layer, effectively avoiding the pipe blockage problem caused by bottom impurities during traditional fixed-depth pumping. This solution uses a booster pump to initially pressurize the water flow in the pumping pipe, followed by a secondary pressure stabilization process using an output pressure stabilizing pump. This eliminates pressure pulsations caused by multiple pump starts / stops or flow rate changes, further reducing pressure fluctuations in the total output pipe and making the output flow more stable.

Description

Technical Field

[0001] This utility model relates to the field of drainage operation technology, specifically a multi-pump collaborative drainage operation platform. Background Technology

[0002] Traditional drainage systems mostly use PID control or simple logic switching, which have weak dynamic response capabilities. Some studies have introduced fuzzy PID control and phase synchronization phase-locked loop technology, but the multi-pump collaborative control strategy is still relatively simple. Near the critical water level, water hammer impact is easily generated due to phase asynchrony, which can lead to incorrect switching or equipment damage.

[0003] Some of the pumps used for drainage cannot adjust their angle according to the water level. They can only be submerged to the bottom of the water. This causes problems such as blockage of the pumping pipes due to the sedimentation of impurities at the bottom of the water, which in turn affects the drainage work of multiple pumps working together. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-pump collaborative drainage operation platform, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-pump collaborative drainage operation platform, comprising a drainage operation platform, a plurality of outward-facing lifting slots on the side of the drainage operation platform, a lifting wheel rotatably mounted between the two walls of the lifting slots, a lifting belt of a certain length fixedly connected to the outer end face of the lifting wheel, a plurality of submersible pumps mounted below the drainage operation platform, the number of submersible pumps corresponding to the number of lifting wheels, a lifting connector mounted on the top of the submersible pump, the lifting connector being connected to the tail end of the lifting belt, a pumping pipe connected to one side of the top of the submersible pump, and a lifting assembly fixedly mounted on the side of the drainage operation platform, the lifting assembly being poweredly connected to the lifting wheel.

[0006] Preferably, a disc-shaped support base is fixed at the center of the top of the drainage operation platform. The support base has an outward-facing opening groove, and a downward-facing connecting groove is provided at the center of the opening groove. The connecting groove passes through the bottom of the drainage operation platform, and the pumping pipes on each side pass through the connecting groove and extend into the opening groove.

[0007] Preferably, the opening slot is provided with a number of booster pumps corresponding to the number of submersible pumps, and the bottom of the booster pumps is connected to the water pumping pipe.

[0008] Preferably, the top of the support base is fixed with four inclined support rods, the top of the support rods is fixed with a cross support frame, and the support frame is installed with a central base.

[0009] Preferably, the collection base is equipped with an output pressure stabilizing pump, and a booster pipe is installed and connected between the bottom of the output pressure stabilizing pump and the top of the booster pump on each side.

[0010] Preferably, the top of the output pressure stabilizing pump is connected to a main output pipe, which serves to collect and aggregate the output.

[0011] This utility model provides a multi-pump collaborative drainage operation platform. It has the following beneficial effects: 1. This solution uses a lifting component to drive a lifting impeller, which in turn drives the submersible pump to rise and fall vertically along the lifting trough. This keeps the submersible pump's pumping hole below the water surface and away from the bottom sediment layer, effectively avoiding the pipe blockage problem caused by the suction of impurities from the bottom when pumping at a fixed depth in traditional methods.

[0012] 2. This solution uses a booster pump to initially pressurize the water flow in the pumping pipeline, and then uses an output pressure stabilizing pump for secondary pressure stabilization. This eliminates pressure pulsations caused by multiple pump starts and stops or flow changes, further reducing pressure fluctuations in the total output pipeline and making the output flow more stable.

Detailed Implementation

[0015] This utility model embodiment provides a multi-pump collaborative drainage operation platform, such as... Figure 1-5As shown, the system includes a drainage operation platform 101. The drainage operation platform 101 has several outward-facing lifting troughs 110 on its side. A lifting wheel 113 is rotatably mounted between the two inner walls of each lifting trough 110. A lifting belt 116 of a certain length is fixedly connected to the outer end face of the lifting wheel 113. Several submersible pumps 114 are located below the drainage operation platform 101, with the number of submersible pumps 114 corresponding to the number of lifting wheels 113. A lifting connector 112 is installed at the top of each submersible pump 114, and the lifting connector 112 is connected to the tail end of the lifting belt 116. A water pumping pipe 111 is connected to one side of the top of each submersible pump 114. A lifting assembly 115 is fixedly mounted on the side of the drainage operation platform 101, and the lifting assembly 115 is poweredly connected to the lifting wheel 113.

[0016] It should be further noted that the submersible pump 114 has a water inlet at the bottom, a water pumping device inside, and good sealing inside.

[0017] It is worth further explaining that the lifting assembly 115 is equipped with a lifting motor. The motor shaft of the lifting motor extends into the lifting groove 110 and is poweredly connected to the lifting wheel 113. When the lifting motor is started, it can drive and rotate the motor, thereby driving the lifting wheel 113 to rotate through the power connection. By lifting the lifting wheel 113, it can drive the submersible pump 114 to adjust its horizontal height.

[0018] Furthermore, a disc-shaped support base 102 is fixed at the center of the top of the drainage operation platform 101. The support base 102 has an opening groove 103 with an outward opening. The opening groove 103 has a connecting groove 119 with a downward opening at its center. The connecting groove 119 passes through the bottom of the drainage operation platform 101, and the pumping pipes 111 on each side pass through the connecting groove 119 and extend into the opening groove 103.

[0019] It should be further explained that the length of the water pumping pipe 111 is sufficient, and the water pumping pipe 111 will not be torn off due to the change in position of the submersible pump 114 during the process of being driven up and down.

[0020] Furthermore, the opening slot 103 is equipped with a number of booster pumps 104 corresponding to the number of submersible pumps 114, and the bottom of the booster pumps 104 is connected to the water pumping pipe 111.

[0021] It is worth further explaining that the booster pump 104 is equipped with a pressurization component, which is used to pressurize and output the water pumped into the water pipe 111.

[0022] Furthermore, four inclined support rods 118 are fixedly provided at the top of the support base 102, and a cross support frame 117 is fixedly provided at the top of the support rods 118. The main base 108 is installed inside the support frame 117.

[0023] Furthermore, the base 108 is equipped with an output pressure stabilizing pump 106, and a booster pipe 109 is installed and connected between the bottom of the output pressure stabilizing pump 106 and the top of the booster pumps 104 on each side.

[0024] Furthermore, the top of the output pressure stabilizing pump 106 is connected to a total output pipe 107, which serves to collect and aggregate the output.

[0025] It should be further noted that the central base 108 contains a controller, which is connected to the control of each pump.

[0026] It is worth noting that flow rate monitors are installed in 104 and 106 respectively to monitor the flow rate of the water.

[0027] The usage method of this solution is as follows: S1. Transport and securely place the drainage operation platform 101 in the target drainage area, such as above or on the bank of a waterlogged area. Start the lifting motor in the lifting assembly 115 to drive the lifting wheel 113 to rotate, and smoothly lower each submersible pump 114 from the lifting trough 110 into the accumulated water through the lifting belt 116 and the lifting connector 112; The initial descent depth can be set slightly higher than the estimated sediment layer at the bottom of the water, for example, one meter below the bottom, to avoid sucking in a large amount of bottom impurities and causing blockages during the initial pumping.

[0028] S2. During drainage operations, the water level changes are monitored manually in real time. When the water level drops, the corresponding lifting component 115 is activated, and the submersible pump 114 at the corresponding position is lifted synchronously and smoothly through the lifting wheel 113 and the lifting belt 116, so that its water pumping hole is always kept at the set working depth. At this time, the controller ensures that the lifting or lowering actions of multiple submersible pumps 114 are highly synchronized in speed and phase, especially near the critical water level. Through precise phase synchronization and phase-locking technology, it avoids sudden changes in water flow and water hammer effect caused by the time difference of each pump's action, protects the pipeline and equipment, and prevents accidental switching. The sufficient length reserved in the pumping pipeline 111 ensures smooth lifting and lowering without pulling.

[0029] S3. Start the water pumping device inside the submersible pump 114 to suck up the accumulated water through the water pumping hole at the bottom; The sucked-in water is transported upward through the pumping pipe 111, passes through the connecting groove 119 and enters the corresponding booster pump 104 in the opening groove 103; The controller coordinates the start of the corresponding booster pump 104 according to the system load or preset strategy. The pressurization component inside the booster pump 104 pressurizes the water flow from the submersible pump 114. The pressurized water is transported through the pressurization pipe 109 to the output pressure stabilizing pump 106 in the collection base 108 on the support frame 117.

[0030] S4. Output pressure stabilizing pump 106 starts, receiving water flow from each booster pipe 109; The core function of the output pressure stabilizing pump 106 is to stabilize the pressure and flow of the aggregated water flow, eliminate pressure pulsation caused by multiple pump start-ups or flow changes, further prevent water hammer effect and ensure stable output water. After pressure stabilization, the water is discharged to a designated area through the main output pipe 107 at the top.

[0031] S5. When the water level drops to a safe threshold or the drainage task is completed, the pressure stabilizing pump 106, the booster pump 104 and the submersible pump 114 are stopped in sequence. Activate all lifting components 115 to synchronously and smoothly lift each submersible pump 114 back below the lifting trough 110; Drain the remaining water in the pipeline and recycle or transfer the drainage operation platform 101.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
