Description

Technical Field

[0001] This invention relates to the field of port transportation and ship loading equipment technology, specifically to an all-weather automatic water loading device and method for a dock ship loader. Background Technology

[0002] Ship loaders are key equipment for bulk cargo loading and unloading operations at large bulk cargo ports. They are mainly used to efficiently load coal and other bulk materials into ship holds. With the rapid development of the port logistics industry, the operating efficiency, automation level, and adaptability to various harsh environments of ship loaders directly determine the throughput capacity and operational benefits of the terminal.

[0003] When loading and unloading easily dusty materials such as coal or mineral powder, ship loaders must use high-pressure spraying systems to suppress dust dispersion and meet environmental protection requirements. Furthermore, regular equipment cleaning and fire safety reserves in the machine room also require significant amounts of water. Therefore, ship loaders typically have their own main water tank to store operational water. However, because ship loaders are mobile devices with high water consumption, ensuring the rapid, safe, and reliable replenishment of the main water tank is crucial for guaranteeing continuous operation and safe production.

[0004] Early water supply methods often involved manual pipe pulling and connection. When the water tank was low on water, workers would drag the water supply hose from the dock to the ship loader and manually connect the interface to add water. Although this method was simple in structure, it was labor-intensive, inefficient, and posed safety hazards in cold or windy weather. To solve these problems, existing technology uses open-type water tank water supply devices. This involves setting up long, open water tanks or funnels along the dock and installing telescopic suction pipes on the ship loader. When water is needed, the suction pipes are inserted into the water tanks to draw water. However, in low-temperature winter conditions, the water in the open-type water tank structure is prone to freezing, making it impossible to insert the suction pipes or causing the pipes to freeze and crack, resulting in a heavy maintenance burden due to freezing. Furthermore, because the ship loader is huge, there are bound to be errors in the stopping position, and vibrations occur during operation. When the rigid suction pipes are inserted into the fixed water tanks, misalignment can cause mechanical collisions, leading to water tank damage and leakage or damage to the suction mechanism. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an all-weather automatic water supply device and method for dock ship loaders, which solves the problems of existing ship loaders using open water tanks freezing and cracking in low-temperature environments, leading to maintenance difficulties, and water tank damage and leakage caused by mechanical collisions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an all-weather automatic water supply device for a dock ship loader, comprising a fixed frame, a ship loader mounted on the upper side of the fixed frame, a transfer water tank mounted on the front side of the ship loader, a conveying pipe connected to the front side of the transfer water tank, a main water tank mounted on the right side of the front wall of the ship loader, the top end of the conveying pipe connected to the main water tank, a water supply mechanism mounted on the inner side of the fixed frame for facilitating water supply to the ship loader, a lifting mechanism mounted on the lower side of the transfer water tank for adjusting the height of the transfer water tank, and a protective mechanism mounted on the top of the transfer water tank for providing protection to the transfer water tank. The water supply mechanism includes a fire hose, which is installed inside the top rear side of the fixed frame. The bottom of the fire hose is connected to multiple water supply pipes, and the front side of the water supply pipe is connected to a water supply pipe. The front end of the water supply pipe is connected to a corrugated pipe, and the front end of the corrugated pipe is connected to a connecting pipe. Multiple hollow plates are fixedly connected to the top front side of the fixed frame. An electric telescopic rod is fixedly connected to the left side of the hollow plate. The output end of the electric telescopic rod passes through the hollow plate and is fixedly connected to a movable block. A connecting rod is rotatably connected to the front side of the electric telescopic rod, and the front end of the connecting rod is rotatably connected to the connecting pipe.

[0007] Preferably, the lifting mechanism includes a base plate, which is fixedly connected to the bottom front side of the ship loader. A groove is provided on the top of the base plate. A motor is fixedly connected to the bottom left side of the front wall of the ship loader. The output end of the motor passes through the groove and is fixedly connected to a bidirectional threaded rod. Slider blocks are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod. A support rod is rotatably connected to the top of the slider. A lifting plate is fixedly connected to the bottom of the transfer water tank. The bottom of the lifting plate is rotatably connected to the top of the support rod.

[0008] Preferably, the protective mechanism includes a hollow top cover, which is fixedly connected to the top of the transfer water tank. A fixing rod is fixedly connected to both the front and rear sides of the interior of the hollow top cover. Cover plates are slidably connected to the left and right sides of the outer walls of the fixing rods. A receiving frame is fixedly connected to the top of the left cover plate. Racks are fixedly connected to the front and rear sides of both cover plates. Gears are rotatably connected to the front and rear sides of the interior of the hollow top cover. The front and rear sides of the two gears are respectively engaged with the corresponding racks.

[0009] Preferably, the water supply mechanism further includes an electric ball valve, which is located on the rear side of the bottom of the outer wall of the water supply pipe, and a manual ball valve is located on the front side of the bottom of the outer wall of the water supply pipe.

[0010] Preferably, the water supply mechanism further includes a drain outlet, which is connected to the bottom end of the connecting pipe, and both the drain outlet and the water supply pipe are provided with an insulation layer on their outer sides.

[0011] Preferably, the lifting mechanism further includes guide rods, and a plurality of guide rods are fixedly connected to the top front and rear ends and left and right sides of the base plate, respectively, with the top ends of the guide rods penetrating the lifting plate.

[0012] Preferably, the lifting mechanism further includes mounting blocks, and multiple mounting blocks are respectively fixedly connected to the top periphery of the lifting plate. Bolts are threadedly connected to the outer side of the mounting blocks, and one end of the bolts passes through the mounting blocks and is threadedly connected to the transfer water tank.

[0013] Preferably, the protective mechanism further includes a spring, which is disposed on the left and right sides of the outer wall of the fixed rod, and the two ends of the spring are fixedly connected to the hollow top cover and the cover plate, respectively.

[0014] Preferably, a submersible pump is installed on the front side of the interior of the transfer tank, the bottom rear end of the delivery pipe passes through the transfer tank and is connected to the output end of the submersible pump, and liquid level sensors are installed on the upper middle part of the rear side of the interior of the transfer tank and the main tank.

[0015] A method for automatically filling a dockside ship loader with water around the clock includes the following steps: S1. When the water supply inside the main water tank on the ship loader is insufficient, the liquid level sensor inside the main water tank will issue a water shortage alarm, and the control system will control the ship loader to move along the track until the ship loader moves to the water supply position where the water supply mechanism is located. S2. Based on the height position of the connecting pipe, start the motor in the lifting mechanism. The motor drives the bidirectional threaded rod to rotate, causing the slider to slide in the groove. Adjust the vertical height of the lifting plate and the transfer water tank through the support rod so that the water inlet height of the transfer water tank matches the downward pressure position of the connecting pipe. S3. Start the electric telescopic rod in the water supply mechanism. The electric telescopic rod pushes the movable block to move, and through the connecting rod, it drives the connecting pipe to rotate forward around the front end of the corrugated pipe. When the connecting pipe rotates and presses down, it pushes the receiving frame on the protective mechanism to move to one side. Using the transmission action of the rack and pinion, it drives the cover plates on both sides to slide outward synchronously, opening the top opening of the transfer water tank until the drain outlet at the front end of the connecting pipe is aligned with the transfer water tank. S4. Open the electric ball valve. The water in the fire water pipe passes through the water inlet pipe, corrugated pipe and connecting pipe in sequence, and is injected into the transfer water tank from the drain outlet. At the same time, the submersible pump in the transfer water tank is started, and the water is pumped into the main water tank through the delivery pipe. The electric ball valve is controlled to open and close according to the feedback signal of the liquid level sensor inside the transfer water tank to maintain the dynamic balance of the water volume in the transfer water tank. S5. After the main water tank is filled with water, close the electric ball valve and submersible pump, control the electric telescopic rod to retract in the opposite direction, drive the connecting pipe to rotate upward and reset. As the connecting pipe disengages from the support frame, the two side covers automatically move towards each other and close under the action of the spring, completing the water filling operation.

[0016] This invention provides an all-weather automatic water-filling device and method for dock ship loaders. It has the following beneficial effects: 1. This invention uses an electric telescopic rod to drive the connecting pipe to rotate to the water inlet angle, injecting water into the transfer tank through the drain outlet, and then delivering it to the main tank via a submersible pump. This not only achieves dynamic balance and automated control of the water supply, but also effectively solves the problem of traditional water tanks freezing in low-temperature environments, which can render the equipment unusable or cause it to crack and require repair. It also eliminates the hidden danger of water tank damage and leakage caused by mechanical collision due to misalignment between the rigid suction pipe and the fixed water tank, thus achieving safe and stable water supply for dock ship loaders around the clock.

[0017] 2. This invention uses a motor to drive a bidirectional threaded rod to rotate, causing the slider to move in opposite directions within the groove. This, in turn, drives the lifting plate and the transfer water tank to rise and fall vertically via a support rod. This allows the height of the transfer water tank to be precisely adjusted according to the actual site conditions, perfectly accommodating connecting pipes at different installation heights or addressing positional deviations caused by ground settlement. This ensures accurate alignment between the drain outlet and the receiving container, while also greatly facilitating the installation and subsequent maintenance of the equipment, thus improving work efficiency.

[0018] 3. During water filling, the connecting pipe rotates forward, pushing the receiving frame and moving the left cover plate. With the help of gear and rack transmission, the covers on both sides open automatically and synchronously. After water filling is completed, the covers close automatically using the spring's restoring force. This effectively prevents dust, fallen leaves, and debris from falling into the transfer water tank when not in operation, ensuring the cleanliness of the water source and avoiding blockage of the submersible pump or contamination of the main water tank by impurities.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 3 , Figure 4 and Figure 5 This invention provides an all-weather automatic water supply device for a dock ship loader, including a fixed frame 1. A ship loader 5 is mounted on the upper side of the fixed frame 1. A transfer water tank 6 is mounted on the front side of the ship loader 5. A conveying pipe 8 is connected to the front side of the transfer water tank 6. A main water tank 7 is mounted on the right side of the front wall of the ship loader 5. The top end of the conveying pipe 8 is connected to the main water tank 7. A water supply mechanism 2 is mounted on the inner side of the fixed frame 1 to facilitate water supply to the ship loader 5. A lifting mechanism 3 is mounted on the lower side of the transfer water tank 6 to adjust the height of the transfer water tank 6. A protective mechanism 4 is mounted on the top of the transfer water tank 6 to provide protection for the transfer water tank 6. The water supply mechanism 2 includes a fire hose 21, which is installed inside the top rear side of the fixed frame 1. Multiple water supply pipes 22 are connected to the bottom of the fire hose 21. A water supply pipe 22 is connected to the front of each water supply pipe 22, and a corrugated pipe 23 is connected to the front end of each water supply pipe 22. A connecting pipe 24 is connected to the front end of the corrugated pipe 23, allowing the connecting pipe 24 to rotate. Multiple hollow plates 25 are fixedly connected to the top front side of the fixed frame 1. An electric telescopic rod 26 is fixedly connected to the left side of each hollow plate 25. The output end of the electric telescopic rod 26 passes through the hollow plate 25 and is fixedly connected to a movable block 27. The electric telescopic rod 26 can push the movable block 27 to move. A connecting rod 28 is rotatably connected to the front side of the electric telescopic rod 26, and the front end of the connecting rod 28 is rotatably connected to the connecting pipe 24. The movable block 27 can push the connecting pipe 24 to rotate via the connecting rod 28, thus supplying water. Mechanism 2 also includes an electric ball valve 29, which is located on the rear side of the bottom of the outer wall of the water supply pipe 22. A manual ball valve 210 is located on the front side of the bottom of the outer wall of the water supply pipe 22. When the electric ball valve 29 fails, the water supply pipe 22 can be closed by rotating the manual ball valve 210. The water supply mechanism 2 also includes a drain outlet 212, which is connected to the bottom end of the connecting pipe 24. Both the connecting pipe 24 and the water supply pipe 22 are provided with an insulation layer 211. The insulation layer 211 prevents the water inside the connecting pipe 24 and the water supply pipe 22 from freezing. A submersible pump 10 is located on the front side of the interior of the transfer tank 6. The rear end of the bottom of the delivery pipe 8 passes through the transfer tank 6 and is connected to the output end of the submersible pump 10. A liquid level sensor 9 is located in the upper middle part of the rear side of the interior of the transfer tank 6 and the main tank 7. The liquid level sensor 9 is used to monitor the liquid level inside the transfer tank 6 and the main tank 7. Specifically, when the water level inside the main water tank 7 on the ship loader 5 is detected to be lower than a preset threshold, the liquid level sensor 9 in the main water tank 7 sends a detection signal. The control system drives the ship loader 5 to move and stop at the designated water supply position. Then, it controls the electric telescopic rod 26 to extend. The output end of the electric telescopic rod 26 pushes the movable block 27 to move. Since the movable block 27 is hinged to the connecting pipe 24 via the connecting rod 28, and the rear end of the connecting pipe 24 is connected to the fixed water supply pipe 22 through the flexible corrugated pipe 23, the thrust of the movable block 27 drives the connecting pipe 24 to deflect forward through the connecting rod 28 until it rotates to the preset water supply angle. At this time, the drain outlet 212 at the front end of the connecting pipe 24 is vertically aligned with the transfer station below. The water inlet of water tank 6 is opened, and then the electric ball valve 29 is opened. The pressurized water source in fire water pipe 21 flows through water inlet pipe 22, corrugated pipe 23 and connecting pipe 24 in sequence, and finally enters the transfer water tank 6 through drain outlet 212. At the same time, the submersible pump 10 inside the transfer water tank 6 is started. The submersible pump 10 continuously pumps water to the main water tank 7 above through delivery pipe 8 to complete the automatic water replenishment operation. This avoids the pipe freezing and cracking caused by freezing in winter and mechanical collision damage caused by rigid contact caused by traditional water tank type water supply. During the water replenishment period, the electric ball valve 29 is intermittently controlled to maintain the dynamic balance of water volume in the transfer water tank 6 based on the feedback signal of the liquid level sensor 9 inside the transfer water tank 6, preventing overflow or pump dry running.

[0023] Reference Figure 1 , Figure 6 and Figure 7 The lifting mechanism 3 includes a base plate 31, which is fixedly connected to the bottom front side of the ship loader 5. A groove 32 is provided on the top of the base plate 31. A motor 33 is fixedly connected to the bottom left side of the front wall of the ship loader 5. The output end of the motor 33 passes through the groove 32 and is fixedly connected to a bidirectional threaded rod 34. Slider 35s are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 34. The motor 33 drives the bidirectional threaded rod 34 to rotate, thereby driving the slider 35 to move. A support rod 36 is rotatably connected to the top of the slider 35. A lifting plate 37 is fixedly connected to the bottom of the transfer water tank 6. The bottom of the lifting plate 37 is rotatably connected to the top of the support rod 36. The slider 35 can push the lifting plate 37 to move vertically through the support rod 36. The lifting mechanism 3 also includes a guide rod 38. Multiple guide rods 38 are fixedly connected to the top front and rear ends and left and right sides of the base plate 31. The top end of the guide rod 38 passes through the lifting plate 37 and can provide guidance for the lifting plate 37. The lifting mechanism 3 also includes a mounting block 39. Multiple mounting blocks 39 are fixedly connected to the top of the lifting plate 37 around the perimeter. The outer side of the mounting block 39 is threaded with a bolt 310. One end of the bolt 310 passes through the mounting block 39 and is threadedly connected to the transfer water tank 6. The transfer water tank 6 can be removed by removing multiple bolts 310. Specifically, by starting the motor 33, the output shaft of the motor 33 drives the bidirectional threaded rod 34 to rotate. Since the threads on both sides of the bidirectional threaded rod 34 rotate in opposite directions, the two sliders 35 will move in opposite or opposite directions in a straight line within the groove 32 of the base plate 31. The horizontal displacement of the sliders 35 is converted into a vertical thrust through the hinged support rod 36, driving the lifting plate 37 to move up or down. During this process, the guide rod 38 passing through the lifting plate 37 provides vertical guidance and limit, ensuring that the lifting plate 37 and the transfer water tank 6 fixed on the lifting plate 37 rise and fall smoothly along the vertical axis. This allows for fine adjustment of the vertical height of the transfer water tank 6 to match the connecting pipe 24 and the drain outlet 212 at different heights, compensating for installation errors or positional deviations caused by ground settlement. It also facilitates lowering the transfer water tank 6 to a lower position for inspection or parts replacement, improving maintenance efficiency.

[0024] Reference Figure 2 , Figure 6 and Figure 7 The protective mechanism 4 includes a hollow top cover 41, which is fixedly connected to the top of the transfer water tank 6. The front and rear sides of the interior of the hollow top cover 41 are fixedly connected to a fixing rod 42. The left and right sides of the outer wall of the fixing rod 42 are slidably connected to a cover plate 43, which can close the transfer water tank 6. The top of the left cover plate 43 is fixedly connected to a support frame 44. The front and rear sides of the two cover plates 43 are fixedly connected to a rack 45. The front and rear sides of the interior of the hollow top cover 41 are rotatably connected to a gear 46. The front and rear sides of the two gears 46 are respectively meshed with the corresponding racks 45. Through the transmission action of the gears 46 and the racks 45, the cover plates 43 on both sides can move synchronously in opposite directions or towards each other. The protective mechanism 4 also includes a spring 47, which is set on the left and right sides of the outer wall of the fixing rod 42. The two ends of the spring 47 are respectively fixedly connected to the hollow top cover 41 and the cover plate 43. Specifically, in terms of protection, under normal conditions, the cover plates 43 on both sides inside the hollow top cover 41 are in a closed state, blocking the external environment. When the connecting pipe 24 rotates forward to perform the water filling action, the connecting pipe 24 contacts and pushes the receiving frame 44 set on the top of the left cover plate 43, forcing the receiving frame 44 to drive the left cover plate 43 to slide to the left. The rack 45 fixed on the outside of the cover plate 43 then drives the gear 46 to rotate. The gear 46 simultaneously drives the rack 45 on the right cover plate 43 to move, thereby realizing the movement of the right cover plate 43. The connecting pipe 24 slides synchronously to the right. Through the transmission action of gear 46 and rack 45, the unilateral thrust of the connecting pipe 24 is converted into the synchronous separation action of the two side cover plates 43, exposing the water inlet of the transfer water tank 6 for water filling. After the water filling operation is completed, the connecting pipe 24 rotates in the opposite direction to reset and detaches from the receiving frame 44. Under the elastic restoring force of the spring 47, the two side cover plates 43 automatically move towards each other and reset to close, resealing the top of the transfer water tank 6 to prevent dust and impurities from falling into the tank during non-working periods and to ensure the cleanliness of the water source.

[0025] Example 2: A method for automatically filling a dockside ship loader with water around the clock includes the following steps: S1. When the water supply inside the main water tank 7 on the ship loader 5 is insufficient, the liquid level sensor 9 inside the main water tank 7 issues a water shortage alarm, and the control system controls the ship loader 5 to move along the track until the ship loader 5 moves to the water supply position where the water supply mechanism 2 is located. S2. Based on the height position of the connecting pipe 24, start the motor 33 in the lifting mechanism 3. The motor 33 drives the bidirectional threaded rod 34 to rotate, causing the slider 35 to slide in the groove 32. Adjust the vertical height of the lifting plate 37 and the transfer water tank 6 through the support rod 36 so that the water inlet height of the transfer water tank 6 matches the downward pressure position of the connecting pipe 24. S3. Start the electric telescopic rod 26 in the water supply mechanism 2. The electric telescopic rod 26 pushes the movable block 27 to move. Through the connecting rod 28, it drives the connecting pipe 24 to rotate forward around the front end of the corrugated pipe 23. When the connecting pipe 24 rotates and presses down, it pushes the receiving frame 44 on the protective mechanism 4 to move to one side. Using the transmission action of the rack 45 and the gear 46, it drives the cover plates 43 on both sides to slide outward synchronously, opening the top opening of the transfer water tank 6 until the drain outlet 212 at the front end of the connecting pipe 24 is aligned with the transfer water tank 6. S4. Open the electric ball valve 29. Water in the fire water pipe 21 flows through the water inlet pipe 22, corrugated pipe 23 and connecting pipe 24 in sequence, and is injected into the transfer water tank 6 from the drain outlet 212. At the same time, the submersible pump 10 in the transfer water tank 6 is started, and the water is pumped into the main water tank 7 through the delivery pipe 8. The electric ball valve 29 is controlled to open and close according to the feedback signal of the liquid level sensor 9 inside the transfer water tank 6, so as to maintain the dynamic balance of water volume in the transfer water tank 6. S5. When the main water tank 7 is filled with water, close the electric ball valve 29 and the submersible pump 10, control the electric telescopic rod 26 to retract in the opposite direction, drive the connecting pipe 24 to rotate upward and reset. As the connecting pipe 24 disengages from the receiving frame 44, the two side covers 43 automatically move towards each other and close under the action of the spring 47, completing the water filling operation.

[0026] Working principle: When the water supply inside the main water tank 7 of the ship loader 5 is insufficient, the liquid level sensor 9 inside the main water tank 7 issues an alarm. At this time, the ship loader 5 is moved to the water intake position, and the electric telescopic rod 26 is activated. The activation of the electric telescopic rod 26 will push the movable block 27 to move. Since the movable block 27 is connected to the connecting pipe 24 through the connecting rod 28, and since the connecting pipe 24 is connected to the water intake pipe 22 through the corrugated pipe 23, when the movable block 27 moves, it will push the connecting pipe 24 to rotate forward to reach the water intake angle. At this time, the drain outlet 212 installed at the front end of the connecting pipe 24 is exactly aligned with the transfer water tank 6 installed on the ship loader 5. Subsequently, the electric ball valve 29 is opened, and the water in the fire water pipe 21 will pass through the water supply pipe 22, the corrugated pipe 23 and the connecting pipe 24 in sequence, and enter the transfer water tank 6 from the drain outlet 212 at the front end of the connecting pipe 24. Then, the submersible pump 10 in the transfer water tank 6 is started. The submersible pump 10 can pump water into the main water tank 7 through the delivery pipe 8, realizing automatic water supply to the main water tank 7, and avoiding the freezing maintenance and water leakage caused by traditional water tank water supply. The electric ball valve 29 is opened and closed by the liquid level sensor 9 inside the transfer water tank 6 to achieve dynamic balance of water supply. Furthermore, during use, by starting the motor 33, the motor 33 will drive the bidirectional threaded rod 34 to rotate, thereby driving the slider 35 to slide inside the groove 32. Since the slider 35 is connected to the lifting plate 37 through the support rod 36, and the lifting plate 37 is guided by the guide rod 38, when the slider 35 moves, the support rod 36 can push the lifting plate 37 to rise and fall vertically, thereby adjusting the vertical position of the transfer water tank 6. It can accommodate the connecting pipe 24 at different heights and improve the maintenance and installation efficiency of the transfer water tank 6. Finally, the cover plates 43 on both sides inside the hollow top cover 41 prevent impurities and garbage from falling into the transfer water tank 6 when water is not being added. When the connecting pipe 24 rotates forward during water addition, it can push the receiving frame 44 to move to the left, thereby moving the left cover plate 43 to the left. Since the racks 45 on the outer sides of both cover plates 43 are engaged with the gears 46, when the left cover plate 43 moves to the left, the transmission action of the racks 45 and the gears 46 can drive the right cover plate 43 to move to the right, thereby opening the water inlet for easy water addition. After water addition is completed, the connecting pipe 24 returns to its original position. At this time, the spring 47 can push the cover plates 43 on both sides to move towards each other, thereby sealing the top of the transfer water tank 6, preventing dust and garbage from entering the transfer water tank 6, and ensuring the cleanliness of the water source in the transfer water tank 6.

10. A method for automatic water loading of a dock ship loader around the clock, characterized in that, A 24 / 7 automatic water loading device for a dock ship loader according to any one of claims 1-9 includes the following steps: S1. When the water supply inside the main water tank (7) on the ship loader (5) is insufficient, the liquid level sensor (9) inside the main water tank (7) issues a water shortage alarm, and the control system controls the ship loader (5) to move along the track until the ship loader (5) moves to the water supply position where the water supply mechanism (2) is located. S2. Based on the height position of the connecting pipe (24), start the motor (33) in the lifting mechanism (3). The motor (33) drives the bidirectional threaded rod (34) to rotate, causing the slider (35) to slide in the groove (32). Adjust the vertical height of the lifting plate (37) and the transfer water tank (6) through the support rod (36) so that the water inlet height of the transfer water tank (6) matches the downward pressure position of the connecting pipe (24). S3. Start the electric telescopic rod (26) in the water supply mechanism (2). The electric telescopic rod (26) pushes the movable block (27) to move. Through the connecting rod (28), the connecting pipe (24) rotates forward around the front end of the corrugated pipe (23). When the connecting pipe (24) rotates and presses down, it pushes the receiving frame (44) on the protective mechanism (4) to move to one side. Using the transmission action of the rack (45) and gear (46), the cover plates (43) on both sides slide outward synchronously, opening the top opening of the transfer water tank (6) until the drain outlet (212) at the front end of the connecting pipe (24) is aligned with the transfer water tank (6). S4. Open the electric ball valve (29). The water in the fire water pipe (21) passes through the water inlet pipe (22), corrugated pipe (23) and connecting pipe (24) in sequence, and is injected into the transfer water tank (6) from the drain outlet (212). At the same time, the submersible pump (10) in the transfer water tank (6) is started, and the water is pumped into the main water tank (7) through the delivery pipe (8). The electric ball valve (29) is controlled to open and close according to the feedback signal of the liquid level sensor (9) inside the transfer water tank (6) to maintain the dynamic balance of the water volume in the transfer water tank (6). S5. When the main water tank (7) is filled with water, close the electric ball valve (29) and the submersible pump (10), control the electric telescopic rod (26) to retract in the opposite direction, drive the connecting pipe (24) to rotate upward and reset. As the connecting pipe (24) disengages from the support frame (44), the two side covers (43) automatically move towards each other and close under the action of the spring (47), completing the water filling operation.
