Description

Technical Field

[0001] The present invention relates to the technical field of waterlogging drainage machines, and in particular to an intelligent waterlogging drainage robot and a water pump assembly thereof. Background Art

[0002] Flood control robots are often used to deal with urban flooding and firefighting. In urban flood control and drainage, flood control robots can be used in series to form a powerful drainage system. Especially under extreme weather conditions such as heavy rains and floods, urban waterlogging problems are serious and it is necessary to quickly remove the accumulated water to ensure the normal operation of the city.

[0003] With the development of cities, more and more underground garages are built with three or even four negative floors. In addition, when floods occur in areas such as subway tunnels, drainage equipment is needed to enter the bottom of the drainage process. Due to the high height difference, one device may not be able to directly discharge the water to the ground. At this time, it is necessary to increase the pressure and increase the lift through the series connection of multiple drainage equipment. The pump components of multiple drainage robots are connected in series and work together to quickly pump the accumulated water to the designated location, effectively reducing the impact of waterlogging. However, in the process of using drainage robots in series, since the front and rear robots are independently controlled, the speed of their suction pumps is basically not unified. Therefore, it is easy for the front robot's fan blades to rotate quickly, the suction intensity is too large, and the rear robot's fan blades rotate slowly. The water flow with excessive flow will directly impact the fan blades of the rear drainage robot, causing damage to the fan blades of the rear robot or damage to the motor. If the rear robot wants to avoid this situation, the fan blades need to maintain high rotation throughout the process, which will also cause energy waste and reduce the endurance of the drainage robot. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent drainage robot and its water pump assembly, which can protect the safety of the fan blades and motor of the drainage pump, ensure the life of the drainage assembly, and also reduce the rotation speed of the drainage pump when the flow rate is small, thereby reducing energy consumption and ensuring the endurance of the drainage robot.

[0005] In order to achieve the above object, the present invention provides a water pump assembly of a flood drainage robot, comprising:

[0006] A water inlet section, wherein a water inlet is provided at one end of the water inlet section, a drainage pump is provided inside the water inlet section, and a first pressure sensor is provided between the water inlet and the drainage pump;

[0007] A water outlet section, the water outlet section is connected to the water inlet section, a second pressure sensor is arranged on the water outlet section, and a water outlet is arranged at one end of the water outlet section facing away from the water inlet section;

[0008] A first controller is electrically connected to the first pressure sensor, the second pressure sensor and the drainage pump.

[0009] Compared with the prior art, the water pump assembly of an intelligent drainage robot in an embodiment of the present invention has the following beneficial effects: the water inlet section of the water pump assembly can be used for direct water inlet during the drainage process, and can also be connected to the water outlet of the water pump assembly of a front-end drainage robot connected in series with the water pump assembly. After the water flows into the water inlet section from the water inlet, the first pressure sensor detects the water pressure and sends the detected result to the first controller. The first controller adjusts the rotation speed of the drainage pump according to the water pressure detection result to match the flow rate and flow velocity of the front drainage. The adjusted drainage pump sends the water flow to the water outlet section. The second pressure sensor in the water outlet section performs a second water pressure detection on the water flow sent by the drainage pump. The measured data is sent to the first controller for judgment and is used for comparison with the first pressure sensor and a preset value to obtain the overall water pressure of the drainage pump. If the difference after comparing with the value of the first pressure sensor is less than the preset value, it can be concluded that the speed of the drainage pump is in the normal working range at this time. If the difference after comparing with the value of the first pressure sensor is greater than the preset value, it is necessary to further increase the speed of the drainage pump to match the overall drainage flow rate. By respectively arranging the first pressure sensor and the second pressure sensor on the water inlet side and the water outlet side of the drainage pump, the water pressure before and after the drainage pump can be monitored in real time and accurately during the series use of the drainage robot, and the drainage pump can be accurately adjusted to adapt to the drainage flow of the front-stage drainage robot, thereby protecting the safety of the fan blades and motor of the drainage pump and ensuring the life of the drainage components.

[0054] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0055] like Figure 1 As shown, a water pump assembly 1 of an intelligent flood drainage robot of a preferred embodiment of the present invention comprises an inlet section 11 and an outlet section 12 connected to each other, and both the inlet section 11 and the outlet section 12 are cylindrically arranged; a water inlet 13 is provided at one end of the water inlet section 11, and the water inlet 13 can be connected to a water absorbing hood 14 for direct water intake during flood drainage, or can be connected to the outlet of the water pump assembly 1 of the front-end flood drainage robot connected in series with the water pump assembly 1. A drainage pump is arranged inside the water inlet section 11, and the blades of the drainage pump rotate to realize the suction effect. A first pressure sensor 15 is arranged between the water inlet 13 and the drainage pump to detect the water pressure of the water flow entering the water inlet section 11.

[0056] The water outlet section 12 is connected to the water inlet section 11. A second pressure sensor 16 is provided on the water outlet section 12 to detect the water pressure of the water flowing out of the water inlet section 11. A water outlet is provided at the end of the water outlet section 12 facing away from the water inlet section 11. The water outlet can be connected to the water inlet of the water pump assembly 1 of the next section of the drainage robot, and can also be connected to water receiving structures such as water hoses to directly discharge water out of the water pump assembly 1.

[0057] The water pump assembly 1 also includes a first controller, which includes a single chip microcomputer and a plc, etc. The first controller is electrically connected to the first pressure sensor 15, the second pressure sensor 16 and the drainage pump. During operation, after the water flows into the water inlet section 11 from the water inlet 13, the first pressure sensor 15 detects the water pressure and sends the detected result to the first controller. The first controller adjusts the rotation speed of the drainage pump according to the water pressure detection result to match the flow rate and flow rate of the previous drainage. The adjusted drainage pump sends the water flow to the water outlet section 12. The second pressure sensor 16 in the water outlet section 12 performs a second water pressure detection on the water flow sent by the drainage pump. The measured data is sent to the first controller for judgment, which is used for comparison with the first pressure sensor 15 and the preset value to obtain the overall drainage situation of the drainage pump. If the difference after comparison with the value of the first pressure sensor 15 is less than the preset value, it can be concluded that the drainage at this time is normal. When the water pump speed is within the normal working range and the difference with the value of the first pressure sensor 15 is greater than the preset value, it is necessary to further increase the speed of the drainage pump to match the overall drainage flow rate; by respectively arranging the first pressure sensor 15 and the second pressure sensor 16 on both sides of the drainage pump, the water pressure before and after the drainage pump can be accurately monitored in real time during the series use of the drainage robot, and the drainage pump can be accurately adjusted to adapt to the drainage flow of the front drainage robot, thereby protecting the safety of the blades and motor of the drainage pump and ensuring the life of the drainage components; on the other hand, the speed of the drainage pump can also be reduced when the flow is small, thereby reducing energy consumption and ensuring the endurance of the intelligent drainage robot.

[0058] In some embodiments of the present invention, the water outlet section 12 includes a water pressure test section 121 and a flow test section 122 connected in sequence, and the water pressure test section 121 and the flow test section 122 are both set to be cylindrical, and the diameter of the water pressure test section 121 is slightly smaller than that of the flow test section 122. Among them, the water pressure test section 121 is used to test the water pressure flowing out of the drainage pump, and the second pressure sensor 16 is set in the water pressure test section 121; the flow test section 122 is used to test the water flow flowing out of the drainage pump, and the flow test section 122 is provided with a flow sensor 123, and the flow sensor 123 is also electrically connected to the first controller. The first controller judges the water flow out of the drainage pump according to the data measured by the flow sensor 123 and the second pressure sensor 16, and further judges the comprehensive working condition of the entire water pump assembly 1 system in combination with the difference between the value measured by the first pressure sensor 15, thereby realizing the full-domain monitoring of the water pump assembly 1 and strengthening the guarantee of the overall working condition of the water pump assembly 1.

[0059] In some embodiments of the present invention, when the water pump assembly 1 of the present application directly performs water absorption operation (i.e., non-series working condition or as a water absorption mechanism of a series mechanism), the water inlet section 11 is detachably connected to a water absorption hood 14 at the water inlet 13, so that the water pump assembly 1 can directly absorb water. The front end of the water absorption hood 14 facing the direction of travel is set to a downwardly curved arc, and the end of the water absorption hood 14 is provided with a water absorption port, which is set vertically downward. Specifically, the bending angle of the water absorption hood 14 is greater than or equal to 90° so that the water absorption port can be set vertically downward, and the inlet plane of the water absorption port is parallel to the water surface. The water absorption port can be closed by the water surface during the absorption process, and the vacuum setting in the water absorption hood 14 is maintained, which is conducive to reducing the minimum water absorption depth of the drainage pump and achieving the minimum residual water accumulation. On the other hand, the water absorption hood 14 with an arc-shaped front section can also prevent debris floating on the water surface from being directly absorbed into the drainage pump, causing damage to the drainage pump. It is understandable that the water absorption cover 14 can also be set to a square or other shape to ensure that its water absorption port is set downward, and no specific limitation is made here.

[0060] Furthermore, a quick-release structure 141 is provided between the water absorption hood 14 and the water inlet section 11. The provision of the quick-release structure 141 enables the water absorption hood 14 of the water pump assembly 1 to be quickly disassembled and assembled, which is beneficial for the drainage robot to quickly assemble the serial water absorption mode and the individual water absorption mode without replacing the entire water pump assembly 1; specifically, the quick-release structure 141 includes a plurality of groups of positioning pins and tower buckles. The positioning pins can complete the radial fixation between the water inlet section 11 and the water absorption hood 14, and the tower buckles can complete the axial tensioning between the water inlet section 11 and the water absorption hood 14.

[0061] In some embodiments of the present invention, the water outlet section 12 is connected to a water hose joint 17 at the water outlet 18. When the water pump assembly 1 of the present application is used as the last section of a series structure or is used alone for drainage, a water hose is generally connected to the water outlet 18 to collect the sucked flood water; the water hose joint 17 is used to connect a water hose, and the end of the water hose joint 17 facing away from the water outlet section 12 is bent downward. The bent water hose joint 17 prevents the water hose from excessively bending when connecting to a horizontally arranged water outlet, thereby protecting the structure of the water hose, preventing the water hose from being damaged during operation, and ensuring the working efficiency of the water pump assembly 1.

[0062] like Figure 2-4As shown, an intelligent drainage robot according to a preferred embodiment of the present invention includes a chassis 2 and a shell 3, a walking part 4 is arranged on the chassis 2, and a water pump assembly 1 of any one of the above embodiments is arranged in parallel at the lower middle part of the chassis 2; the water pump assembly 1 is arranged in at least two groups and arranged in parallel with each other, and the multiple groups of water pump assemblies 1 are interconnected and can be raised and lowered synchronously; the shell 3 is covered on the chassis 2, and a accommodating cavity is formed in the shell 3 for accommodating the engine and other components of the drainage robot, and a plurality of lighting warning lights 31 are arranged on the outer side of the shell 3, which can light up when working to remind nearby workers that a drainage robot is working here; an inspection port 32 is also arranged on the shell 3 to provide maintenance operations, and a fuel filling port 33 is also arranged at the rear of the shell 3.

[0063] The drainage robot also includes a hydraulic system, which includes a power supply mechanism 5 and a hydraulic integrated module 6. The power supply mechanism 5 is arranged in the accommodating cavity and provides power to the hydraulic integrated module 6. Specifically, the power supply mechanism 5 includes an engine, etc., which burns fuel to provide power for the hydraulic integrated module.

[0064] The hydraulic integrated module 6 connects the water pump assembly 1, the traveling parts 4 arranged on both sides of the chassis 2 and the external hydraulic device, and provides power to the water pump assembly 1, the traveling parts 4 and the external hydraulic device respectively; specifically, the hydraulic integrated module includes a hydraulic oil pump 62, which is used to transmit power to the traveling parts.

[0065] like Figure 6 As shown, the hydraulic integrated module 6 and the energy supply mechanism 5 are also connected to a second controller, which includes a device controller, a wireless communication module and a display module. The sensor in the hydraulic system transmits the parameters of the hydraulic system to the second controller, and the second controller transmits the parameters to the display module at the operator through the wireless communication module. The display personnel can therefore know the hydraulic parameters in the system at this time. When the parameters of the hydraulic module are different from the hydraulic parameters required by the external hydraulic device at this time, the hydraulic parameters in the device can be adjusted through the device controller. Specifically, when adjusting the hydraulic parameters, the speed of the energy supply mechanism 5 can be increased or decreased so that the energy supply mechanism 5 provides different power for the hydraulic integrated module 6. The throttle valve and hydraulic pressure regulating valve inside the hydraulic integrated module can also be controlled by the device controller to achieve remote adjustment of different output powers of the hydraulic integrated module. Further, the control mode of the wireless communication module includes remote control control or terminal software control. Remote control control is a remote remote control panel control that comes with the device when it leaves the factory. The remote control panel comes with a device status display screen that can view device information in real time. The terminal software control system is a device with a 5G network that uses terminal software to control and view device information in real time.

[0066] Furthermore, the second controller also includes an intelligent control system, which can intelligently adjust the working parameters of the equipment according to different working environments of the equipment, abnormal conditions of the equipment (such as excessive internal temperature of the equipment, excessive hydraulic temperature, abnormal oil pressure, etc.) and different working conditions (walking, drainage, driving hydraulic tools with different parameters).

[0067] The drainage robot controls the drainage of the water pump, the overall movement and the external hydraulic device through the equipment controller of the hydraulic integrated module. The second controller receives the information of the hydraulic system and adjusts the internal hydraulic parameters according to this information, realizing the overall intelligence of the drainage robot and improving the automation level of the drainage robot and the degree of compatibility with external hydraulic tools.

[0068] In some embodiments of the present invention, the hydraulic system also includes a sensor component and an adjustment component, which are electrically connected to a second controller. The sensor component serves as an information source for the second controller, and the adjustment component serves as an actuator of the second sensor to adjust the parameters of the hydraulic system. The sensor component collects parameters in the hydraulic system and uploads them to the second controller. The second controller sends a signal to the operator's display module through a wireless communication module. The operator transmits the parameters that need to be adjusted back to the second controller, and the device controller of the second controller controls the adjustment component to adjust the parameters of the hydraulic integrated module.

[0069] In some embodiments of the present invention, the sensor assembly includes a hydraulic flow sensor, a pressure sensor and a temperature sensor, and the hydraulic flow sensor, the pressure sensor and the temperature sensor are designed in multiple, and the multiple hydraulic flow sensors, pressure sensors and temperature sensors are distributed in various pipelines of the hydraulic system to realize the monitoring of the overall hydraulic parameters of the hydraulic system; the actuator assembly includes a throttle valve 611 and a pressure regulating valve 612, and the throttle valve 611 and the pressure regulating valve 612 are both electronically controlled proportional valves, and the throttle valve 611 and the pressure regulating valve 612 are respectively used to adjust the flow and hydraulic pressure of the hydraulic oil output to the hydraulic integrated module to meet the hydraulic parameter requirements of the water pump assembly 1, the walking part 4 and the external hydraulic device. Specifically, the hydraulic flow sensor includes an ultrasonic flowmeter and a turbine flowmeter 615, etc., which are used to accurately detect the flow of the hydraulic integrated module.

[0070] In some embodiments of the present invention, the sensor assembly also includes a speed sensor. The speed of the energy supply mechanism 5, that is, the speed of the engine, indicates the power output by the engine at this time. The parameters of the speed sensor can represent the power of the engine at this time. The second controller adjusts the speed of the energy supply mechanism 5 according to the signal of the speed sensor, that is, adjusts the power of the engine according to the hydraulic requirements of the water pump assembly 1, the traveling part 4 and the external hydraulic device, so that the power output of the engine meets the requirements of the water pump assembly 1, the traveling part 4 and the external hydraulic device.

[0071] like Figure 6 As shown, in some embodiments of the present application, a plurality of hydraulic flow sensors, pressure sensors and temperature sensors are distributed in the hydraulic oil circuit of the present application, which respectively collect the hydraulic parameters of the hydraulic device leading to the water pump assembly 1, the walking member 4 and the outside, and a speed sensor is provided in the energy supply mechanism 5. During the collection process, the hydraulic flow sensor, the pressure sensor and the temperature sensor respectively transmit the flow, hydraulic pressure and temperature parameters of each part of the hydraulic integrated module 6 to the second controller, and the speed sensor also transmits the real-time speed of the energy supply mechanism 5 to the second controller; after the second controller collects the hydraulic oil information and speed information at each part, it transmits the information to the operator through the wireless communication module. The display module allows the display personnel to know the hydraulic parameters in the system and the speed of the energy supply mechanism at this time, and can compare the hydraulic parameters required by the external hydraulic device based on these parameters; if the hydraulic parameters of the hydraulic integrated module 6 are different from the hydraulic parameters required by the external hydraulic device at this time, the hydraulic parameters in the hydraulic integrated module 6 can be directly adjusted through the throttle valve 611 and the pressure regulating valve 612 connected to the equipment controller to adapt to the hydraulic parameters required by the external hydraulic device; the second controller can also directly adjust the speed of the energy supply mechanism 5 to adjust the power input to the hydraulic integrated module 6, and further adjust the parameters in the hydraulic integrated module 6. The second controller receives the information of the hydraulic system and adjusts the internal hydraulic parameters based on this information, thereby improving the automation of the drainage robot and the degree of adaptation to external hydraulic tools.

A plurality of output interfaces 614 are provided on the valve block, and the plurality of output interfaces 614 are respectively connected to the water pump assembly 1, the travel part 4 and the external hydraulic device. The hydraulic integrated valve block can adjust the flow of each output interface 614 according to the signal of the second controller.

[0073] like Figure 8 As shown, in some embodiments of the present invention, a fuel tank 21 and a hydraulic oil tank 22 are integrated on the chassis 2. The arrangement of the fuel tank 21 and the hydraulic oil tank 22 on the chassis 2, on the one hand, strengthens the strength of the chassis 2, and on the other hand, since the chassis 2 is immersed in water for a long time during operation, the fuel tank 21 and the hydraulic oil tank 22 can be well cooled. Furthermore, the pipeline connecting the fuel tank 21 and the hydraulic oil tank 22 is also immersed in water at the same time, which also has a good cooling effect. The fuel tank 21 is connected to the energy supply mechanism 5 to provide power for the engine of the energy supply mechanism 5, and the hydraulic oil tank 22 is connected to the hydraulic integrated module to provide the hydraulic integrated module with circulating hydraulic oil. Specifically, an oil level sensor is designed in the fuel tank 21, and the main function of the oil level sensor is to transmit the oil level information of the fuel tank to the control terminal in real time.

[0074] In some embodiments of the present invention, two fuel tanks 21 are provided, which are respectively arranged at the two ends of the width direction of the chassis 2. The two separate fuel tanks 21 are symmetrically arranged, which optimizes the layout of the chassis 2 and makes a lot of space for installing the water pump assembly 1 in the middle. Moreover, the fuel tanks 21 on both sides can obtain heat dissipation from water on both sides, which improves the heat dissipation effect compared with a single fuel tank 21; further, the bottoms of the two fuel tanks 21 are interconnected, which is conducive to the mutual flow of oil and prevents one fuel tank 21 from being used too much and the other fuel tank 21 from being used too little; the hydraulic oil tank 22 is arranged at the front end of the walking direction of the chassis 2, so that the outer shell 3 of the hydraulic oil tank 22 continuously has water flowing through its surface during the walking process of the drainage robot, which has a good convection heat dissipation effect and reduces the heat dissipation pressure of the hydraulic oil during the circulation process. Furthermore, the inlet and outlet oil pipes 23 of the water pump assembly 1 are made of steel pipes, which extend from the front of the chassis 2 to the rear of the chassis 2. When the water pump assembly 1 is draining water in the water, the hydraulic oil continuously flows in the steel pipes of the inlet and outlet oil pipes 23, and the heat therein is transferred to the surface of the steel pipe through heat conduction. When the external water flows, part of the temperature of the surface of the steel pipe is taken away, thereby improving the heat dissipation effect.

The shock absorber seat 25 on the hydraulic oil tank 22 is used to support the hydraulic oil pump 62 in the hydraulic integrated module, and the hydraulic oil pump 62 is connected to the walking member 4. The shock absorber seat 25 isolates the vibration of the hydraulic oil pump 62 during the operation of the hydraulic oil pump 62, so as to prevent the chassis 2 and the hydraulic oil tank 22 from being affected by the vibration of the hydraulic oil pump 62, and the shock absorber seat 25 on the chassis 2 is used to isolate the vibration of the engine. Specifically, the shock absorbing seat 25 is provided with elements such as springs.

When the crawler 41 rotates around the truss 42, the drainage robot walks. The truss 42 is provided with a driving wheel train, a buffer wheel train and an adjusting wheel train. The driving wheel train is arranged at the rear end of the truss 42 to drive the crawler 41 to rotate; the buffer wheel train is arranged at the bottom and the front end of the bottom of the truss 42 to reduce the impact during walking and protect the crawler 41 and the truss 42; the adjusting wheel train is arranged at the top of the truss 42 to adjust the tightness of the truss 42 to adapt to different walking needs.

[0077] In some embodiments of the present invention, the driving wheel system includes a driving motor 43 and a driving wheel 44. The driving wheel 44 is connected to the driving motor 43.

The driving motor 43 drives the driving wheel 44 to rotate, and the driving wheel 44 is engaged with the crawler 41. The rotating driving wheel 44 can provide power for the crawler 41 to keep the drainage robot walking stably.

The buffer wheel 45 is connected to one end of the track 41 in the length direction, specifically located at the front end of the track 41 in the traveling direction. When the track 41 encounters an obstacle and is impacted during its movement, a buffer is provided between the track 41 and the truss 42 to prevent the impact from directly acting on the truss 42 rigidly connected to the chassis 2, and also prevents many mechanical components on the chassis 2 from being subjected to a large impact; the buffer wheel 45 system also includes multiple groups of supporting wheel groups 46 arranged at the bottom of the truss 42. The supporting wheel group 46 is used to filter the fine vibrations at the bottom of the track 41 during the movement.

The end of the first buffer member 451 away from the truss 42 is connected to the rotating shaft of the buffer wheel 45. When the equipment moves forward, the track 41 corresponding to the buffer wheel 45 is the first to be hit and the impact force is the greatest.

[0082] In some embodiments of the present invention, a fixing hole 472 and a groove 473 are provided on the adjustment plate 471. A fixing screw is inserted into the fixing hole 472. An adjusting screw fixed to the truss 42 is inserted into the groove 473. A plurality of fixing grooves 473 may be provided.

The adjustment plate 471 can rotate along the extension direction of the groove 473 with the fixing screw as the center. The rotation of the adjustment plate 471 drives the tension wheel 47 to rotate. When the tension wheel 47 rotates, the tightness of the crawler 41 can be adjusted. During the rotation of the adjustment plate 471, the adjusting screw moves along the extension direction of the groove 473. When the tension wheel 47 reaches a suitable position, the adjusting screw is locked by a nut, so that the tension wheel 47 and the adjustment plate 471 are fixed to the truss 42, and the tensioning process of the crawler 41 is completed.

After being pressurized, the adjusting wheel 48 presses against the adjusting block 483 on the adjusting push rod 481 and applies pressure to the elastic member 482. After working for a period of time, if the track 41 becomes loose, the elastic member 482 loses the downward pressure and provides reverse pressure in the direction of the track 41, so that the adjusting wheel 48 provides tensioning force to the track 41, ensuring that the track 41 always maintains a tensioned state during operation; specifically, the elastic member 482 includes a spring.

The measured data is sent to the first controller for judgment and is used for comparison with the first pressure sensor 15 and a preset value to obtain the overall drainage situation of the drainage pump. If the difference after comparison with the value of the first pressure sensor 15 is less than the preset value, it can be concluded that the rotation speed of the drainage pump is within the normal working range at this time.
