[0026] like Figure 1-5 As shown in the specific embodiment: A liquid transport box includes a box structure, which is formed by welding together a bottom unit 1, two end wall units 2 and two side wall units 3; an internal support frame 4 is provided inside the box structure to support and strengthen the box structure; a detachable grid plate 5 is laid inside the box structure and on top of the internal support frame 4; the box structure is equipped with a liquid level sensing and hoisting balance system, including a hoisting unit 7 and a liquid level sensor 6 installed on the vertical surface of the box structure. The hoisting unit 7 includes a hoisting frame 701, and a traction motor 702 is provided at each of the four corners of the hoisting frame 701. Each traction motor 702 is connected to and drives a sling 704 for raising and lowering; hooks 703 for connecting lifting equipment are provided at the upper ends of the four corners of the hoisting frame 701.

[0027] The signal output terminal of the liquid level sensor 6 is connected to the control terminal of the traction motor 702 for communication, and is used to control the raising and lowering of the sling 704 according to the liquid level signal to adjust the tilt of the box.

[0028] Preferably, the bottom of the inner support frame 4 is welded and fixed to the bottom unit 1, and the periphery of the inner support frame 4 is welded and fixed to the inner walls of the two end wall units 2 and the two side wall units 3 at corresponding positions; there are multiple liquid level sensors 6, which are set on different facades of the box structure. The inner support frame 4 includes multiple parallel longitudinal grid frames and at least one transverse grid frame; the transverse grid frame is perpendicularly inserted and fixedly connected to all the longitudinal grid frames to form a grid-like frame structure, and the longitudinal grid frames and the transverse grid frames are welded together from rectangular square tubes 401.

[0029] Preferably, the bottom unit 1 includes two parallel H-shaped steel bottom side beams 101 and several bottom cross beams 102 erected between the two bottom side beams 101. The cross section of the bottom cross beams 102 is C-shaped. The bottom side beams 101 and the bottom cross beams 102 are spliced ​​and welded together to form a frame, and a sealing plate 103 is welded to the upper surface of the frame.

[0030] Preferably, the end wall unit 2 has a frame welded together from corner pieces 202, an upper crossbeam 201, a lower crossbeam 204, and two side corner posts 203. The outer side of the frame is covered with an end skin 206, and multiple reinforcing posts 205 are welded to the inner side of the end skin 206 for reinforcement. A drain valve 8 is provided at the bottom of the end wall unit 2; a handle is welded to the upper crossbeam 201, and a folding ladder is provided on the end skin 206.

[0031] Preferably, the side wall unit 3 has a frame consisting of multiple side wall columns 301 welded together with side wall beams 302 connected therebetween, and the outer side of the frame is covered with a side skin 303; wherein the bottom of the side wall columns 301 is welded and fixed to the bottom side beam 101 of the bottom unit 1.

[0032] Preferably, the grating plate 5 is horizontally arranged inside the box structure, and its top surface maintains a distance of 400mm to 500mm from the opening at the top of the box. Alternatively, the grating plate 5 is composed of multiple steel plates vertically assembled into a honeycomb structure, arranged in sheets or blocks, with each honeycomb structure positioned by a cross-shaped positioning block 402. To achieve rapid assembly and accurate positioning of multiple grating plates, a cross-shaped positioning block 402 is provided at the junction of adjacent grating plates; each arm of the cross-shaped positioning block 402 engages or inserts with the side of the corresponding grating plate, ensuring a flat splicing surface and accurate positioning.

[0033] In another embodiment, the number of liquid level sensors 6 is eight, and they are respectively arranged at diagonal positions of two end wall units 2 and two side wall units 3.

[0034] In the technical solution of this utility model: 1. The enclosed box, constructed from a welded frame, with its internal crisscrossing support structure welded to the inner wall, enhances the overall rigidity of the box structure, preventing the liquid from bulging or deforming during transport.

[0035] 2. A removable grid plate is installed at the liquid level inside the tank. When fully loaded, its grid structure has a significant shearing and blocking effect on the liquid surface sloshing.

[0036] 3. Liquid level sensors distributed on the four sides of the tank monitor the liquid level in real time and send the signals back to the traction motor on the lifting unit. This allows for dynamic adjustment of the locking length to change the tank's tilt, thus enabling the liquid level to be restored during lifting.

[0037] The usage process of this utility model: S1. Before filling with liquid, climb to the top of the tank using the folding ladder on the end wall. If necessary, the grid plate 5 can be removed for subsequent internal cleaning or maintenance. S2. Non-sensitive liquid is injected into the tank through the opening at the top of the tank via a pipe. After the liquid is injected, it will fill the tank and be divided and buffered by the internal support frame 4 and the grid plate 5 to reduce shaking.

[0038] S3. Once full, close the top cover (top cover is an optional setting), and it can be transported by road using standard container trucks or flatbed trucks. Because its structural strength comes from the welded box body and internal support frame, no additional tank is required, resulting in a lighter weight and effectively reducing transportation energy consumption.

[0039] S4. Lifting and unloading are carried out. The hooks of the lifting equipment are connected to the hooks 703 at the four corners of the lifting unit 7, and then leveling and lifting are performed. The system is started, and the liquid level sensors 6 distributed in the four corners of the tank and in different facades begin to monitor the height of the liquid level in the tank in real time.

[0040] If the liquid level is not level (indicating that the liquid is sloshing due to inertia, causing the tank's center of gravity to shift), the sensor signal will be transmitted to the control system of the traction motor 702. The control system will immediately calculate and adjust: tighten the sling 704 on the side with the lower liquid level, while simultaneously loosening the sling on the side with the higher liquid level. Through this dynamic adjustment, the tank is kept in a stable state or quickly restored to a stable state in the air, greatly avoiding the risk of tipping over.

[0041] S5. After the transport box is hoisted to the destination, open the drain valve 8 at the bottom of the end wall unit 2 to drain the liquid.
