Description

Technical Field

[0001] This invention relates to the field of drainage pump valve technology, and more specifically to a mobile pump truck for flood control and drainage that is resistant to clogging. Background Technology

[0002] On the front lines of urban flood control, emergency drainage at construction sites, and flood prevention, you often see a piece of equipment that looks like a "mobile water hose"—this is the mobile pumping unit for flood control and drainage. Simply put, it's a mobile fire brigade equipped with its own "heart" (power system) and "blood vessels" (pump body and pipelines), specifically designed to "suck" up low-lying water in the shortest possible time and then "spit" it out into distant rivers or drainage networks.

[0003] The core technology of this pump truck lies in one word—"sucking" directly and "spitting out." Its operating mode is direct pumping and direct discharge, primarily used in emergency flood control. In such dangerous situations, unlike sewage treatment plants, it doesn't require prior filtration through screens. Its core task is "rapid transfer"—moving accumulated water (whether clean rainwater or sewage mixed with mud, sand, and debris) from point A to point B (such as rivers, sewers, or low-lying areas) in the shortest possible time. As for mud, garbage, and even less serious pollutants mixed in the water, they are usually discharged directly with the water, without interception or separation, provided the pump body isn't clogged (heavily polluted sewage is still transported to a sewage treatment plant by tanker truck). They can be moved directly to the flooded area by trailer and operate. The inlet pipe simply extends into the sewage to pump away all the mud, sand, and garbage. Because it eliminates the complex filtration process, deployment is extremely fast; it can start pumping immediately and move to the next dangerous area after pumping dry, making it ideal for emergency rescue.

[0004] Structurally, it typically consists of a diesel engine (providing powerful performance without external power), a sewage pump (the core working component), and a mobile chassis (trailer-mounted or vehicle-mounted for rapid deployment). To cope with complex sewage environments, modern pump trucks also integrate intelligent control systems, hydraulic outriggers (for vehicle stabilization), and even lighting systems to ensure stable operation over extended periods, enabling all-weather operation even at night or in adverse road conditions.

[0005] However, conventional concrete pump trucks with existing technology have the following two main shortcomings:

[0006] ① Existing anti-clogging technologies mainly rely on impeller design: they emphasize the "non-clogging" characteristics of the impeller (such as vortex or open impellers), attempting to accommodate impurities by expanding the flow channel, preventing them from getting stuck in the blade gaps, and using centrifugal force to move the impurities away from the blades, allowing them to rotate once along the pump's inner wall from the inlet pipe and exit directly from the outlet pipe on the side wall, avoiding contact or collision with the blades. However, when encountering large solid particles (such as stones, concrete fragments, plastic bottles, etc.), mechanical jamming may still occur. Once jamming occurs, it often leads to motor overload and burnout or instantaneous damage to the mechanical seal, causing the equipment to be scrapped on-site and unable to complete the emergency drainage task.

[0007] ② Inadequate pre-pump filtration design easily leads to "secondary clogging": Although some equipment has filters and grilles installed in the pre-pump pipeline to prevent large particles from entering the pump body, their structure is mostly a simple fixed grille, which can only perform fixed interception. The intercepted impurities need to be cleaned by stopping the machine. In actual pumping, fibrous materials (such as aquatic plants and plastic bags) and sticky impurities in the sewage can easily and quickly clog the filter surface, causing the inlet channel to be completely blocked. This design not only fails to provide protection, but also forces operators to frequently stop the machine for cleaning, greatly reducing drainage efficiency and violating the original intention of "continuous operation" of emergency equipment.

[0008] In summary, existing technologies lack a synergistic mechanism for anti-clogging mobile pumping vehicles used in flood control and drainage that can effectively intercept lethal large particles (preventing internal pump jamming) while automatically removing intercepted impurities (preventing filter clogging). Therefore, a new technical solution for anti-clogging mobile pumping vehicles is urgently needed, focusing solely on protecting the pumping vehicle itself and addressing the issues of emergency jamming and equipment failure caused by large particulate impurities, without considering subsequent sewage treatment. Summary of the Invention

[0009] In view of the prior art, the purpose of this invention is to provide a design for a mobile pumping vehicle for flood control and drainage that can prevent parallel blockages online, and which can maintain pump operation without affecting the process of clearing blockages, and has good continuous operation capability.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a mobile pumping vehicle for flood control and drainage that is resistant to clogging, comprising a vehicle body, a power unit and a pump body, wherein the vehicle body is used to carry the power unit and the pump body, the main shaft of the power unit extends into the pump body to drive the impeller assembly inside the pump body, and the pump body includes a pump chamber, an inlet end and an outlet end.

[0011] It also includes an anti-clogging mechanism, with the inlet and outlet openings facing the same direction, and both openings connected to one side where the anti-clogging mechanism is installed. The other side of the anti-clogging mechanism is provided with an inlet pipe and an outlet pipe opposite to the inlet and outlet ends, respectively. The anti-clogging mechanism includes a shell, a water flow chamber, a rotating filter disc, and a rotating unit. The rotating filter disc is rotatably arranged relative to the shell and includes a water-blocking partition plate located in the middle of the rotating filter disc, dividing the rotating filter disc into two equal parts, filter frame A and filter frame B. The rotating unit is used to drive the rotating filter disc to rotate regularly in the circumferential direction relative to the shell.

[0012] As a further provision of the above scheme, the rotating unit includes a hydraulic motor with a built-in reducer, a controller, and an in-pump sensing and monitoring unit. The controller is used to receive the detection signal data from the in-pump sensing and monitoring unit, control the hydraulic motor connected to the rotating filter disc to start, and drive the rotating filter disc to rotate circumferentially.

[0013] As a further feature of the above scheme, the controller is configured with a commutation strategy and an operating strategy based on the signal data detected by the pump-in-pump sensing and monitoring unit. The commutation strategy includes configuring a pressure threshold and generating a command signal when the actual pressure wave value obtained by the pump-in-pump sensing and monitoring unit is greater than the preset threshold. The operating strategy includes monitoring the generation of the command signal, configuring a control command to start the hydraulic motor, and recording the change in the pressure wave value before and after the control command is generated, comparing it with the configured data. Furthermore, it generates control data based on the generation interval of the configured data and the change in the pressure wave value. The control data is used to send a signal to the power unit to stop working when the change in the pressure wave value is too low or when the generation interval of the control command is too low.

[0014] As a further feature of the above scheme, the pump in-sense monitoring unit includes a water pressure sensor located at the water inlet end of the pump body and a waterproof pressure sensor located in the anti-clogging mechanism. The waterproof pressure sensor is set against the rotating filter plate and is used to trigger a feedback signal to the controller after the water resistance increases due to the accumulation of impurities in either filter frame A or filter frame B. The rotating motor switches the circumferential rotation of filter frame A and filter frame B within the housing.

[0015] As a further feature of the above scheme, the rotation angle of the rotating filter disc driven by the hydraulic motor is fixed, and it is started periodically, triggered, or remotely by a controller. The main shaft of the hydraulic motor is connected to the rotating shaft of the rotating filter disc, and the rotating filter disc is also provided with several waterproof bearings and flat bearings relative to the housing to support its rotation.

[0016] As a further feature of the above scheme, the anti-blocking mechanism is configured to form two water passage channels A and B in the stationary state of the rotating unit through a water-blocking partition plate. The two ends of water passage A are respectively connected to the immersion pipe and the inlet end, while water passage B is connected to the drain end and the outlet pipe.

[0017] As a further feature of the above solution, the filter frame is provided with an interception grid at least at the bottom, and the outer arc wall is disposed close to the inner wall of the housing, with the gap between the two being smaller than the mesh size of the interception grid.

[0018] As a further feature of the above scheme, the power unit, pump body and anti-blocking mechanism are all fixedly mounted on a vehicle plate that is hinged to the vehicle body. The vehicle plate is hinged at one end near the anti-blocking mechanism, and a support electric cylinder is provided between the other end and the vehicle body. The support electric cylinder is used to drive the vehicle plate to swing relative to the vehicle body. The vehicle body is also provided with support wheels and lifting support feet for supporting the vehicle body at the end away from the anti-blocking mechanism.

[0019] Beneficial Effects: This invention, through its anti-clogging mechanism with a rotatable double filter frame structure, achieves automatic interception of impurities and self-cleaning of the filter frames. This enables continuous operation without shutdown, effectively avoiding the secondary clogging problems of impeller jamming or filter screen clogging common in traditional pump trucks. It significantly improves drainage efficiency. Furthermore, its structural design greatly reduces the impact of blockages and the cleaning process on water flow, thus minimizing the impact on the pump. Its intelligent control strategy automatically switches filter frames based on pressure changes and promptly triggers overload protection to shut down the equipment when clogging is severe or cleaning is ineffective. It detects switching intervals and pressure differences to trigger automatic shutdown protection in case of clogging failure, enhancing the reliability and safety of unattended operation. The small gap design between the outer arc wall of the filter frame and the inner wall of the housing, along with bearing support, ensures filtration efficiency and smooth rotation. The swingable design and support structure of the vehicle platform further optimize impurity cleaning and equipment operation stability. Overall, this invention significantly improves the practicality, durability, and emergency response capabilities of mobile pump trucks in complex sewage environments, providing strong support for flood control and drainage work.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0028] refer to Figure 1-6 The illustrated mobile pumping unit for flood control and drainage, designed to prevent clogging, includes a vehicle body 1, a power unit 2, and a pump body 3. The vehicle body 1 carries the power unit 2 and the pump body 3. The main shaft of the power unit 2 extends into the pump body 3 to drive the impeller assembly within the pump body 3. The pump body 3 includes a pump chamber 31, an inlet end 32, and a drain end 33. It also includes an anti-clogging mechanism 4. The inlet end 32 and the drain end 33 have commensurate openings, and both openings are connected to one side of the anti-clogging mechanism 4. The other side of the anti-clogging mechanism 4 is respectively equipped with… The inlet pipe 8 and outlet pipe 9 are positioned opposite to the inlet end 32 and the outlet end 33, respectively. The anti-clogging mechanism 4 includes a housing 41, a water flow chamber 42, a rotating filter disc 43, and a rotating unit 5. The rotating filter disc 43 is rotatably arranged relative to the housing 41 and includes a water-blocking partition plate 45 located in the middle of the rotating filter disc 43. The water-blocking partition plate 45 is also used to divide the rotating filter disc 43 into two equal parts, filter frame A441 and filter frame B442. The rotating unit 5 is used to drive the rotating filter disc 43 to rotate regularly in the circumferential direction relative to the housing 41.

[0029] As shown in the accompanying drawings, the pump truck of the present invention is characterized by its anti-clogging structural design. In practice, this design addresses the application background and environment of flood control and drainage pump trucks, which require rapid drainage. Secondly, the operating environment is often characterized by complex water conditions such as floods and ponds, particularly the presence of impurities that can easily affect blade operation, such as gravel, wood chips, fiber cloth, and plastic bags. Thirdly, traditional pump trucks, when faced with such impurities, either rely on the impeller's "non-clogging" design to allow the impurities to pass through, but large particles can easily cause jamming; or a fixed filter screen is installed before the pump, but the accumulation of impurities leads to "secondary clogging," requiring frequent shutdowns for cleaning, severely impacting drainage efficiency.

[0030] The core innovation of this invention lies in the anti-clogging mechanism 4 integrated at the pump body's inlet end 32 and outlet end 33. This mechanism cleverly achieves the coordinated work of impurity interception and automatic cleaning through a rotatable rotating filter disc 43, allowing continuous operation without stopping the machine. During this process, the inlet end 32 and outlet end 33 together occupy the entire rotating filter disc 43. Whether it is water inlet or outlet, the water flow rate remains the same during rotation, without significant fluctuations, thus avoiding unstable pump load. In other words, compared to normal filtration or cleaning designs, the device of this invention maintains a basically consistent water flow area during the unclogging process, and normal water flow will not be affected (excluding impurity blockage).

[0031] Specifically, refer to Figure 2 , Figure 5 As shown, the rotating filter disc 43 is divided into filter frames A441 and filter frames B442 by the water-blocking partition plate 45.

[0032] In the initial working state, the filter frame A441 is opposite to the inlet pipe 8 and the inlet end 32 of the pump body 3, forming a water passage A51. At this time, impurities in the sewage will be intercepted by the interception grid 46 of the filter frame A441. The filtered water (referring to sewage that has had large particles removed by the interception grid 46) enters the pump chamber 31, is pressurized by the impeller and discharged from the drain end 33, and flows to the outlet pipe 9 through the water passage B52 (formed by the filter frame B442, the drain end 33 and the outlet pipe 9).

[0033] As impurities accumulate within filter frame A441, water resistance increases. A waterproof pressure sensor within the anti-clogging mechanism 4 detects this change and sends a feedback signal to the controller. Based on a preset reversing strategy, the controller generates a command signal when the detected pressure wave exceeds a preset threshold, activating the hydraulic motor 53 of the rotating unit 5. The hydraulic motor 53 drives the rotating filter disc 43 to rotate 180 degrees circumferentially, causing filter frame A441, which was previously in operation, to rotate to a position opposite to the drain end 33 and the outlet pipe 9. Meanwhile, the previously unused filter frame B442 rotates to a position opposite to the inlet pipe 8 and the inlet end 32, while other aspects remain unchanged.

[0034] At this point, filter frame B442 begins to intercept impurities, collecting and blocking them within the water passage A51. Meanwhile, the impurities intercepted inside filter frame A441, rotated to the drain end, are flushed out by the high-pressure water flow from drain end 33 and discharged through outlet pipe 9, completing the cleaning of filter frame A441. This process continues until the next rotation unit 5 is triggered, exchanging cycles with filter frame B442.

[0035] This design allows the two filter frames to work and clean alternately, automatically removing intercepted impurities without stopping the pump, effectively avoiding the problem of "secondary clogging." Simultaneously, the interception grille 46 prevents large solid particles from entering the pump chamber 3, thus preventing the risk of impeller jamming. This filtration method not only improves drainage efficiency and meets emergency needs without requiring pump shutdown, but also adapts to various complex water quality environments. Whether it's urban flooding with floating debris or rural low-lying areas mixed with mud, branches, and other debris, it can stably and efficiently carry out drainage operations. Furthermore, the entire impurity removal process requires no manual intervention, greatly reducing the labor intensity of operators and avoiding safety risks for personnel working in harsh flood control environments, further ensuring the continuity and reliability of drainage work. This design, combining dual protection and automatic cleaning, significantly enhances the practicality and durability of the mobile pump truck in flood control and drainage tasks, making it one of the key pieces of equipment in response to sudden flood disasters.

[0036] In addition, refer to Figure 6 In addition to the system strategy, the controller of rotating unit 5 is also configured with an operating strategy and a reversing strategy. The operating strategy monitors the generation interval of command signals and the change in pressure wave value after reversal: ① If the pressure wave value still exceeds the preset threshold after two filter frame switching and there is no significant change, it indicates that the filter frame may also have a blockage problem and has not been effectively resolved by backflushing; ② If the interval between multiple control command generation is too low, that is, the system causes frequent switching between the two filter frames based on control commands, it indicates that there are too many impurities in the current water and the blockage is relatively serious, leading to frequent triggering of cleaning. In these cases, the controller will send a signal to power unit 2 or the terminal for further manual or intelligent judgment to issue a stop operation command to protect the equipment from further damage. This intelligent monitoring and protection mechanism further improves the reliability and safety of the pump truck.

[0037] like Figure 6The system shown, under normal operating conditions, has three triggering schemes for the anti-clogging mechanism 4 to activate the rotation unit 5. Firstly, the controller periodically triggers the reversal via a timer during pump and valve drainage. This is because, as is characteristic of this invention, switching the filter frame does not affect the water flow rate; therefore, periodic filter frame switching not only avoids equipment operation obstruction but also prevents impurity accumulation. Secondly, the operator can remotely initiate the switching. This aims to enhance proactivity, including manually judging the current impurity content of the water and proactively initiating the switching to avoid and reduce the impact of impurity accumulation on equipment use. Thirdly, the switching and anti-clogging actions are automatically triggered based on sensor feedback such as pump water pressure. It is worth noting that the first two methods and the third method of automatic switching are stored as two separate sets of data. Within the automatically triggered system, such as... Figure 6 The system strategy triggering flowchart based on water pressure changes is based on the sensor acquiring the water pressure change from the rear end of the anti-clogging mechanism 4 to the pump inlet during normal water pumping. It is worth noting that the sensor settings described in this invention are not completely fixed. They can be set at the front and rear ends of the anti-clogging mechanism 4, the water inlet of the pump body, or other reasonable locations that can achieve the interception of the anti-clogging mechanism 4 through pressure difference feedback, depending on the actual implementation. When the pressure value is greater than the preset value (generally calculated based on the water pressure in the pipe during normal pump operation, and also considering the pressure value under blockage), a control command will be triggered to switch the filter frame. The filter frame that has intercepted impurities will be moved to the drainage side, and the empty filter frame (after the blockage is cleared) will be moved to the water inlet side. The water pressure should return to the normal level, thereby solving the water pressure change problem in the system. Furthermore, while eliminating water pressure changes, The system records the trigger signal and the pressure value at the time of triggering. The trigger signal is calculated by combining the interval time of multiple trigger signals. When the interval of multiple (at least 3) trigger signals is less than the preset threshold (10 seconds), it may indicate that the filter frame has failed to self-clean. Impurities are stuck in the filter frame and cannot be self-cleaned, resulting in frequent switching of the filter frame. The change in pressure value indicates that the pressure value does not decrease after switching the filter frame, which also indicates that the filter frame impurity removal is ineffective. That is, the blockage intercepted by the anti-blockage mechanism 4 has failed to self-clean. If the above two problems continue, they may eventually lead to complete blockage of the water inlet pipe, which may lead to problems such as overload and burnout of the pump power unit motor. Therefore, if either of the above two problems occurs, the system will trigger the shutdown of the equipment until the problem is manually resolved and restarted.

[0038] In terms of structural details, the outer arc wall of the filter frame is positioned close to the inner wall of the housing 41, with a gap smaller than the mesh size of the intercepting grille 46. This ensures that wastewater can only enter the filter frame through the intercepting grille 46, preventing large particles from flowing directly into the pump body through the gap. The rotating filter disc 43 is also equipped with several waterproof bearings and flat bearings relative to the housing 41 to support its rotation, ensuring smooth rotation and reducing the difficulty and torque requirements of filter frame switching under high-pressure water flow.

[0039] In the overall layout of the pump truck, the power unit 2, pump body 3, and anti-clogging mechanism 4 are all fixedly mounted on the platform 10, which is hinged relative to the vehicle body 1. The platform 10 is hinged at one end near the anti-clogging mechanism 4, and a support electric cylinder 11 is provided between the other end and the vehicle body 1. A lifting support leg 13 is provided at the end away from the anti-clogging mechanism 4 to support the vehicle body 1. This can drive and support the platform 10 to swing relative to the vehicle body 1 and tilt the vehicle body 1, thereby adjusting the angle between the pump body and the anti-clogging mechanism 4. This allows the equipment to tilt at the required angle (generally less than 35°) to facilitate equipment operation. When too much water accumulates on the A51 side of the water passage, it is allowed to return to the inlet pipe 8 by weight, especially for heavier stones. At the B52 end of the water passage, it is beneficial to cooperate with the high-pressure water flow to clean impurities away from the filter frame and allow them to enter the outlet pipe 9.

[0040] The pump truck body 1 is also equipped with support wheels 12, which facilitates short-distance movement and position adjustment of the pump truck. The lifting support legs 13 are also used to stably support the vehicle body during operation and prevent shaking during operation.

[0041] In summary, this invention, through its unique anti-clogging mechanism design, particularly the combination of a rotatable double filter frame structure and an intelligent control strategy, successfully solves the problem of pump jamming and filter clogging that commonly occur in existing flood control and drainage mobile pumping vehicles when facing complex sewage environments. It achieves efficient, continuous, and reliable emergency drainage operations, providing strong technical support for emergency scenarios such as urban flooding rescue and construction site drainage.

[0042] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
