[0002] A water purification truck is a specialized vehicle integrating advanced water treatment technology, capable of rapidly converting polluted water sources, including rivers, lakes, wells, and even lightly contaminated water sources, into safe drinking water in complex environments. Its core lies in a highly integrated multi-stage purification system, typically including pretreatment, fine filtration, and disinfection, effectively removing suspended solids, bacteria, viruses, and harmful chemicals. This equipment is mobile, highly responsive, and requires no fixed infrastructure, playing an irreplaceable role in natural disaster emergency rescue, field training, water supply security in remote areas, and temporary water supply for large-scale events. It not only represents the practical application of mobile water treatment technology but also serves as a vital logistical force for ensuring public welfare and national defense, embodying the modern emergency support concept of delivering clean water to the front lines. Most water purification vehicles on the market obtain drinking water by drawing surface water or domestic water and purifying it on-board.

The snow melting mechanism 5 is used to melt and filter the collected snow and ice. The snow melting mechanism 5 is fixed to the bottom of the inner cavity of the vehicle compartment 2. By setting up the snow melting mechanism 5, it is the core pretreatment unit of the entire water purification vehicle. It is responsible for quickly and efficiently converting the collected solid snow and ice into liquid water and performing preliminary purification. It integrates heating, melting and multi-stage filtration functions and is a key link to ensure the subsequent water quality. The liquid storage mechanism 6 is used to store melted ice and snow. The liquid storage mechanism 6 is fixed to the bottom of the inner cavity of the carriage 2. By setting up the liquid storage mechanism 6, it serves as a safe storage unit for purified drinking water. It is made of food-grade materials and usually has an antibacterial coating or ultraviolet disinfection module inside to ensure water quality safety during storage. Its capacity is calculated to meet specific rescue or supply needs. A connecting frame 3 extends through the outer side of the carriage 2, and a material-grabbing robotic arm 7 is fixed to the inner wall of the connecting frame 3. This robotic arm 7 is used to switch the material-grabbing state. By setting up the connecting frame 3, a structurally reinforced and sealed channel is formed on the side wall of the carriage 2, providing a stable mounting base and movement space for the material-grabbing robotic arm 7, while preventing external dust and pollutants from entering the interior of the carriage 2. The material-grabbing robotic arm 7 is a key actuator for realizing automated ice and snow collection. It has multi-degree-of-freedom motion capabilities, can flexibly adjust the posture and position of the material-grabbing head, adapt to complex and uneven snow environments, and efficiently complete the grabbing and transportation of ice and snow. A transfer box 8 is fixedly installed on the bottom surface of the inner cavity of the carriage 2. A flexible hose 9 runs through the outer side of the transfer box 8, passing through the connecting frame 3 and connecting to the material-collecting robotic arm 7. By setting up the transfer box 8 and the flexible hose 9, a buffer and connection hub is formed between the material collection and snow melting process. The transfer box 8 temporarily stores the ice and snow collected by the robotic arm, and the ice and snow slurry is continuously transported to the snow melting mechanism 5 by negative pressure or gravity through the flexible hose 9. The flexible design of the flexible hose 9 adapts to the movement of the robotic arm.

[0023] The snow melting mechanism 5 includes a heating furnace 51, which is fixed to the bottom of the inner cavity of the carriage 2. The heating furnace 51 integrates a pumping system and a heating system. A feed pipe 52 is fixed to the liquid inlet end of the heating furnace 51, with the end of the feed pipe 52, away from the heating furnace 51, penetrating the outer surface of the transfer box 8. The heating furnace 51 serves as the energy center and melting core of the snow melting mechanism 5. It integrates a high-efficiency heat exchanger and a combustion system, enabling rapid and controllable heating of the snow and ice slurry to the melting temperature. Its integrated pumping system is responsible for drawing the snow and ice mixture from the transfer box 8, ensuring a continuous supply of materials. The feed pipe 52 serves as a conveying channel connecting the transfer box 8 and the heating furnace 51, and is made of low-temperature resistant and heat-insulating materials to prevent freezing or heat loss during transport.

[0024] A high-pressure pump 53 is fixedly installed at the outlet end of the heating furnace 51. A purification tank 54 is fixedly installed at the end of the high-pressure pump 53 away from the heating furnace 51. A sealing cover 58 is movably connected to the opening of the purification tank 54. A handle 59 is welded to the upper surface of the sealing cover 58. A filter plate 510 is welded to the top of the inner wall of the sealing cover 58. There are several filter plates 510, which are evenly distributed on the top of the inner wall of the sealing cover 58. The filter plates 510 are pressed and fitted against the bottom surface of the inner cavity of the purification tank 54. By setting up the high-pressure pump 53, the power is provided for transporting the water after snow melting and the filtration pressure is increased. The high pressure generated forces the melted water through the subsequent filter media, which can effectively improve the filtration efficiency and impurity removal rate. By setting up the purification tank 54, it serves as the main container for multi-stage physical filtration, and can accommodate multiple filter elements inside. The sealing cover 58 and the handle 59 form a quick-opening sealed top cover for the purification tank 54, which is convenient for periodic replacement or cleaning of the internal filter elements. The handle 59 facilitates manual operation. The filter plate 510 is the core component for performing the filtration function. Multiple filter plates 510 are arranged in a stacked or parallel manner. Each layer carries a filter screen of different precision, from coarse filtration to fine filtration, to remove impurities such as silt, suspended solids, some microorganisms and colloids from the water step by step. Its squeeze fit with the bottom of the tank ensures that the water flow must pass through the filter media without short circuit.

[0025] A first connecting pipe 55 passes through the side of the purification tank 54 away from the high-pressure pump 53. A control valve 56 is fixed to the end of the first connecting pipe 55, and a second connecting pipe 57 is fixed to the outlet end of the control valve 56.

The control valve 56 is used to precisely control the flow direction and on / off of the filtered water, which facilitates system maintenance or process switching. The storage tank 61 serves as the final product water storage container. It has a large capacity and is made of stainless steel or food-grade polyethylene. An activated carbon plate inside adsorbs residual chlorine, odors, organic pollutants, and some heavy metals in the water, achieving deep purification and improving taste. A fixing plate 62 securely fixes the storage tank 61 to the floor of the vehicle compartment 2, preventing it from shaking during vehicle operation. A water outlet valve 63 serves as the interface for accessing clean water. This standard water pipe connector can be connected to a faucet or water supply hose 9 to directly supply drinking water to the outside.

A wrapping cylinder 75 is welded between the opposite surfaces of the second rotating ball 78 and the first rotating ball 74. The axes of the first limiting frame 73 and the second limiting frame 77 have a certain degree of inclination. By setting the fixed column 71 and the support plate 72, a rigid support foundation for the material handling robotic arm 7 is formed, providing a top suspension fulcrum and a bottom auxiliary support, respectively, to ensure the structural stability of the entire arm when bearing load and moving. By setting up a first limiting frame 73, a first rotating ball 74, a second limiting frame 77, a second rotating ball 78, and a wrapping cylinder 75, a unique double-ball-joint multi-degree-of-freedom motion joint is formed. The first rotating ball 74 and the second rotating ball 78 rotate within the first limiting frame 73 and the second limiting frame 77, while also having a certain tilt angle. This arrangement allows the wrapping cylinder 75 connecting the two to achieve complex pitch and yaw compound movements, providing a flexible range of motion far exceeding that of traditional single joints. This allows the robotic arm to extend out of the carriage 2 during use and retract when the vehicle is moving, thus playing a role in obstacle avoidance.

A first gear 79 is welded to the outer surface of the second rotating ball 78, and the first gear 79 meshes with the second gear 713. By setting up the first enclosure frame 710, the first stepper motor 711, the first rotating rod 712, the second gear 713, and the first gear 79, a precision transmission system for driving the core rotational motion of the robotic arm is formed. The first enclosure frame 710 provides protection and mounting space for the first stepper motor 711. The first stepper motor 711 serves as the drive source, providing precise and controllable rotational motion. The first rotating rod 712 transmits torque. The second gear 713 meshes with the first gear 79 fixed on the second rotating ball 78, converting the rotational motion of the motor into the rotation of the second rotating ball 78 within its limiting frame, thereby driving the entire wrapping cylinder 75 to rotate within a small range around the axis of the second limiting frame 77. This is the key drive for the robotic arm to cover the lateral working range.

[0028] A material-grabbing mechanism 76 is fixed to the inner wall of the packaging cylinder 75. The material-grabbing mechanism 76 includes a fixed cylinder 761, which is welded to the inner wall of the packaging cylinder 75.

A sliding block 764 is welded to the outer surface of the sliding cylinder 763 and is slidably connected to the inner cavity of the track groove 762. By setting up the fixed cylinder 761, the track groove 762, the sliding cylinder 763, and the sliding block 764, the telescopic linear motion unit of the material-grabbing mechanism 76 is formed. The fixed cylinder 761 is fixed to the packaging cylinder 75 as a mounting base. The track groove 762 is a precision-machined guide groove. The sliding cylinder 763 is the main body that performs the telescopic motion. The sliding block 764 is connected to the sliding cylinder 763 and slides in the track groove 762, ensuring that the sliding cylinder 763 can only make precise linear extension and retraction movements along the axis of the fixed cylinder 761, thereby realizing the extension and retraction of the working radius of the material picking head, so that it can reach the snow surface at different distances.

A hydraulic cylinder 768 is fixed to the inner wall of the connecting frame 767. A moving rod 769 is provided at the output end of the hydraulic cylinder 768. The moving rod 769 is fixedly connected to the sliding block 764. By setting the fixing ring 765 and the telescopic tube 766, a fluid channel extension component is formed that is synchronized with the telescopic movement of the material taking mechanism 76. One end of the telescopic tube 766 is fixed, and the other end moves with the sliding cylinder 763, ensuring that the water flow and ice-snow mixture can be transferred from the inside of the material taking head to the transfer box 8 and the hose 9 without leakage. The connecting frame 767, hydraulic cylinder 768, and moving rod 769 form a power system for driving the extension and retraction of the sliding cylinder 763. The hydraulic cylinder 768 provides strong linear thrust and pull, ensuring that the material take-up head can overcome the resistance of snow accumulation to perform digging insertion or stable recovery. The moving rod 769 directly pushes the sliding block 764. The structure is compact and the power is abundant.

A rolling bearing 7614 is fixed to the outer surface of the second rotating rod 7612, and the outer ring of the rolling bearing 7614 is fixed to the inner wall of the sliding cylinder 763. By setting up the second wrapping frame 7610, the second stepper motor 7611, the second rotating rod 7612, the fan blade 7613, and the rolling bearing 7614, a material conveying and crushing power system inside the material receiving head is formed. The second wrapping frame 7610 provides installation space for the motor. The second stepper motor 7611 drives the second rotating rod 7612 to rotate at high speed. The fan blade 7613 is mounted on the second rotating rod 7612. Its rotation generates a strong negative pressure at the front end of the material intake head, drawing in loose ice and snow. At the same time, the fan blade 7613 itself can also initially break up the ice and snow. The rolling bearing 7614 provides stable support for the high-speed rotating second rotating rod 7612, ensuring smooth operation.

[0031] A feed cylinder 7616 is welded to the end of the sliding cylinder 763. The lower surface of the feed cylinder 7616 has a feed inlet. The end of the second rotating rod 7612, away from the second stepper motor 7611, is rotatably connected to the inner cavity of the feed cylinder 7616. An arc-shaped blade 7615 is welded to the outer surface of the second rotating rod 7612. By setting up the feed cylinder 7616 and the arc-shaped blade 7615, the final execution terminal and material handling unit of the material handling mechanism 76 are constituted. The feed cylinder 7616 is the component that directly contacts the ice and snow; its lower feed inlet is designed to be close to the snow surface for efficient intake of ice and snow. The arc-shaped blade 7615 is installed at the end of the second rotating rod 7612, located inside the feed cylinder 7616 or near the feed inlet. As the second rotating rod 7612 rotates at high speed, it can effectively cut and break up the clumps of hard snow or thin ice, prevent clogging of the feed inlet, and initially separate the ice and snow from any small amount of debris such as dry grass that may be mixed in, ensuring that the sucked-in material is easier to melt and filter in subsequent processes.

[0032] Working Principle: During operation, the vehicle is parked near the snow source. The operator starts the material-collecting robotic arm 7 via the control panel. The first stepper motor 711 drives the second rotating ball 78 to rotate, causing the wrapping cylinder 75 to adjust to a suitable angle. The hydraulic cylinder 768 pushes the sliding cylinder 763 to extend, placing the end feed cylinder 7616 into the snow layer. Subsequently, the second stepper motor 7611 starts, driving the second rotating rod 7612 to rotate at high speed. The arc-shaped blade 7615 at its end cuts and breaks up the ice and snow. At the same time, the fan blade 7613 generates a strong negative pressure inside the feed cylinder 7616, sucking in ice and snow debris through the feed inlet. Under the action of negative pressure, the sucked-in ice and snow are continuously transported through the channels inside the sliding cylinder 763 and the telescopic pipe 766, and through the hose 9 to the transfer box 8 in the carriage 2 for temporary storage.

[0033] When the amount of ice and snow in the transfer box 8 reaches a certain level, the snow melting mechanism 5 is activated. The water pumping system built into the heater 51 draws the ice and snow mixture from the transfer box 8 through the feed pipe 52. The high-efficiency heating system of the heater 51 quickly melts the ice and snow mixture into liquid water. The melted water is pressurized by the high-pressure pump 53 and pumped into the purification box 54. The water first passes through the multi-layer filter plates 510 installed on the sealing cover 58. These filter plates 510 form a multi-stage physical barrier, removing larger impurities such as silt, suspended particles, and vegetation debris from the water step by step, completing the initial coarse filtration and fine filtration.

[0034] After initial filtration, the water flows out of the purification tank 54 through the first connecting pipe 55. The control valve 56 opens, and the water flows through the second connecting pipe 57 into the core of the storage mechanism 6—the storage tank 61. The activated carbon plate inside the storage tank 61 further treats the water, adsorbing residual odors, organic pollutants, and some trace heavy metals, further improving water quality and taste. The water after this deep purification meets direct drinking standards and is safely stored in the storage tank 61, awaiting use. The fixing plate 62 ensures that the storage tank 61 remains stable and does not move while the vehicle is in motion.

[0035] Example 2, as Figures 11-12 As shown, the present invention provides a technical solution: the continuous material handling robotic arm 7 includes a first limiting frame 101 and a second limiting frame 107. The first limiting frame 101 is welded to the inner wall of the connecting frame 3. A first rotating arm 102 is rotatably connected to the inner cavity of the first limiting frame 101. The end of the first rotating arm 101 is connected to a second rotating arm 103 through a harmonic reducer. The end of the second rotating arm 103 away from the first rotating arm 101 is connected to a connecting gripper 104 through a harmonic reducer. A snow suction head 105 for snow suction is fixed in the inner cavity of the connecting gripper 104. A connecting pipe 106 is fixed at the top of the snow suction head 105. The connecting pipe 106 is fixed on the upper surface of the first rotating arm 101. The second limiting frame 107 is welded to the inner wall of the connecting frame 3. A damper 109 is rotatably connected to the inner cavity of the second limiting frame 107. A limiting post 108 is rotatably connected to the end of the damper 109. The limiting post is welded to the lower surface of the first rotating arm 102. By setting the first limiting frame 101, the first rotating arm 102 can rotate freely within the inner cavity of the connecting frame 3. By setting the first rotating arm 102 and the second rotating arm 103, the snow suction head 105 can move in all directions, thus enabling it to suck up snow from different areas of the road surface. By setting the connecting pipe 106 and the snow suction head 105, the sucked snow can be guided into the inner cavity of the snow melting mechanism 5.

[0036] When water is needed, the user or operator simply opens the outlet valve 63 located on the side wall of the vehicle compartment 2. Clean drinking water stored in the storage tank 61 flows out under gravity, either through an external water pipe or directly into containers. After water collection or operation is completed, all valves and motors are closed. The material handling robotic arm 7 retracts and resets into the connecting frame 3 under the drive of the hydraulic cylinder 768 and the first stepper motor 711. The heating furnace 51 stops working, and the entire system enters standby mode. The vehicle can be moved to a new work location at any time, repeating the above process to achieve continuous and mobile field water supply.
