[0037] See also Figures 1 to 8 The present application provides a liquid storage tank, which includes: a cylinder 100, a fixed head 200 and a movable head 300. The cylinder 100 extends horizontally. The cylinder 100 includes a first end and a second end. A fixed seat 120 is convexly provided on the top surface of the second end of the cylinder 100, and a sliding member 130 is provided on the fixed seat 120. The sliding member 130 can move along the axial direction of the cylinder 100 relative to the fixed seat 120. In the axial direction of the cylinder 100, the sliding member 130 can exceed the outside of the cylinder 100. The fixed head 200 is fixed to the first end of the cylinder 100 to be sealed and connected to the cylinder 100. The movable head 300 is rotatably connected to the sliding member 130, and the movable head 300 can move along the axial direction of the cylinder 100 with the sliding member 130, so that the movable head 300 can be opened and closed and covered on the second end of the cylinder 100. The movable head 300 has a closed state and an open state. When the movable seal 300 is in a closed state, the movable seal 300, the fixed seal 200 and the cylinder 100 enclose a sealed space 400 for containing liquid. When the movable seal 300 is in an open state, the movable seal 300 is away from the cylinder 100, so that the sealed space 400 is opened and the liquid in the sealed space 400 can be discharged.

[0038] When liquid waste needs to be transported and processed, the movable head 300 rotates around the sliding member 130, and the movable head 300 and the sliding member 130 both move along the axis of the cylinder 100 toward the center of the cylinder 100, so that the movable head 300 covers the second end of the cylinder 100, and the movable head 300 switches to a closed state, and the movable head 300, the cylinder 100 and the fixed head 200 enclose a sealed space 400.

[0039] After the liquid waste is input into the sealed space 400, the staff can transport the liquid waste by transferring the liquid storage tank.

[0040] When the liquid storage tank moves to the destination, the fixed head 200 rotates around the sliding member 130, and the movable head 300 and the sliding member 130 both move along the axis of the cylinder 100 away from the center of the cylinder 100, so that the movable head 300 moves away from the cylinder 100 and opens the sealed space 400. The movable head 300 switches to an open state, and the liquid in the sealed space 400 is discharged to the outside through the second end of the cylinder 100, thereby effectively improving the transportation efficiency of liquid waste and reducing labor costs and time costs.

[0041] See also Figure 1 and Figure 3 In this embodiment, the cylinder 100 extends in a horizontal direction, and two ends of the cylinder 100 are respectively a first end and a second end.

[0042] In some embodiments, an infusion hole may be provided on the barrel 100 to facilitate external liquid waste to enter the sealed space 400 through the infusion hole.

[0043] In some embodiments, a manhole may be provided on the cylinder 100 to facilitate workers to enter the cylinder 100 through the manhole to inspect, repair, and clean the liquid storage tank.

[0044] See also Figure 1 and Figure 3 In this embodiment, a plurality of first reinforcement rings 110 are further sleeved on the outer circumference of the cylinder 100. The plurality of first reinforcement rings 110 are arranged at intervals along the axial direction of the cylinder 100. The first reinforcement rings 110 extend along the circumference of the cylinder 100 to strengthen the structural strength of the cylinder 100 and ensure the reliability of the liquid storage tank.

[0046] See also Figures 1 to 6 , Fig. 9 and Fig.10 In this embodiment, a fixing seat 120 is protruded upward from the top of the second end of the cylinder 100. A sliding member 130 is arranged on the fixing seat 120, and the sliding member 130 can move axially along the cylinder 100 relative to the fixing seat 120.

[0047] In some embodiments, two fixing seats 120 are protruding upward from the top of the second end of the cylinder 100. The two fixing seats 120 are arranged at intervals along the left-right direction. The two fixing seats 120 are symmetrically arranged along the central plane of the axis of the cylinder 100, and the central plane extends in a direction perpendicular to the left-right direction.

[0048] In some other embodiments, a reinforcing plate 121 is disposed between the two fixing seats 120. The reinforcing plate 121 extends in the left-right direction, and both ends of the reinforcing plate 121 are respectively fixedly connected to the two fixing seats 120 to ensure the reliability and stability of the fixing seats 120.

[0049] See also Figures 3 to 6 In this embodiment, there are two sliding members 130 corresponding to the two fixing seats 120. The two sliding members 130 are slidably disposed on the two fixing seats 120 respectively.

The rotating shaft portion 132 is located at one end of the sliding portion 131 away from the center of the cylinder 100. The rotating shaft portion 132 is used for rotationally connecting with the movable head 300.

[0051] In other embodiments, the rotating shafts 132 of the two sliding members 130 are coaxially arranged, and the axes of the two rotating shafts 132 extend in the left-right direction. When the movable head 300 is rotatably connected with the two rotating shafts 132, the movable head 300 can not only move forward and backward with the sliding part 131 relative to the fixed seat 120, but also rotate around the axis of the rotating shaft 132, so that the movable head 300 can switch between the closed state and the open state.

[0052] In some embodiments, in the axial direction of the cylinder 100, the shaft portion 132 can move and partially extend beyond the outside of the cylinder 100, so that the rotation axis of the movable head 300 can be located outside the cylinder 100, which facilitates the rotation of the movable head 300 around the shaft portion 132 and ensures the convenience of connection and disassembly between the movable head 300 and the cylinder 100.

[0053] In some embodiments, a limiting member 140 may be provided on the fixing seat 120. The limiting member 140 may abut and limit a portion of the sliding member 130, thereby limiting the sliding stroke of the sliding member 130 and preventing the sliding member 130 from falling out of the fixing seat 120. In other embodiments, the limiting member 140 may be a limiting baffle.

[0054] In other embodiments, in the axial direction of the cylinder 100, a limit member 140 can be passed through one end of the sliding shaft close to the center of the cylinder 100. The limit member 140 can push against and limit the fixed seat 120 to prevent the sliding member 130 from escaping from the fixed seat 120, thereby ensuring the safety and reliability of the liquid storage tank.

[0055] The limiting member 140 may be a limiting pin or a limiting shaft, so that the sliding member 130 can be slidably limited on the fixing seat 120 .

The first sealing ring 150 can be used to be sealed with the movable head 300, thereby ensuring the sealing performance between the cylinder 100 and the movable head 300, and preventing liquid from leaking from the gap between the cylinder 100 and the movable head 300.

[0057] In some embodiments, a sealing groove is recessed on one end surface of the first sealing ring 150 facing the movable head 300 , and the sealing groove extends along the circumference of the cylinder 100 for sealing connection with the movable head 300 .

[0058] In other embodiments, the first sealing ring 150 is integrally formed with the cylinder 100 to ensure the structural strength and sealing performance of the liquid storage tank.

[0059] In some embodiments, a sealing ring is provided in the sealing groove to further improve the sealing performance between the cylinder 100 and the movable head 300 .

[0060] See also Figure 1 , Figure 3 and Fig. 9 In this embodiment, the fixed head 200 is fixedly connected to the cylinder 100 so as to be able to seal and form a sealed space 400 .

[0061] In some embodiments, the fixed head 200 is welded to the first end of the cylinder 100 to ensure the connection strength between the fixed head 200 and the cylinder 100 .

[0062] See also Figure 1 , Figure 3 and Fig. 9 In this embodiment, the movable head 300 is rotatably connected to the shaft portion 132 of the sliding member 130, so that the movable head 300 can move along the axial direction of the cylinder 100 with the sliding member 130, and can also rotate around the shaft portion 132 to switch between a closed state and an open state.

[0063] When the movable head 300 moves to a closed state, the movable head 300 rotates around the axis of the shaft portion 132 toward the second end of the cylinder 100, and the movable head 300 follows the sliding portion 131 to move toward the center of the cylinder 100, so that the movable head 300 covers the cylinder 100, and the movable head 300 is tightly connected to the cylinder 100.

[0064] When the movable head 300 switches from a closed state to an open state, the movable head 300 rotates around the axis of the shaft portion 132 away from the second end of the cylinder 100, and the movable head 300 follows the sliding portion 131 to move away from the center of the cylinder 100, so that the movable head 300 is separated from the cylinder 100, and the second end of the cylinder 100 is opened, thereby facilitating the discharge of liquid in the sealed space 400.

[0065] See also Figure 2 , Figure 4 , Figure 6 and Fig.10 In this embodiment, a connection portion 310 is protruded upward from the top of the movable head 300. The connection portion 310 is rotatably connected to the shaft portion 132, so that the connection portion 310 and the movable head 300 can rotate around the shaft portion 132, thereby realizing the state switching of the movable head 300.

[0066] In some embodiments, the top of the movable head 300 is provided with two connecting parts 310 corresponding to the sliding member 130. The two connecting parts 310 are arranged at intervals along the left and right directions. The two connecting parts 310 can be respectively sleeved on the opposite ends of the rotating shaft part 132, so that the two connecting parts 310 can rotate around the rotating shaft part 132.

[0067] In other embodiments, the two connecting parts 310 are respectively located at the left and right ends of the rotating shaft part 132. The connecting part 310 is detachably provided with a fixed shaft 311, which extends in the left and right directions. The fixed shaft 311 can pass through the two connecting parts 310 and the rotating shaft part 132 to realize the rotation connection of the connecting part 310 and the rotating shaft part 132.

[0068] See also Figure 2 , Figure 4 , Figure 6 and Fig.10 In this embodiment, a second sealing ring 320 is sleeved on the outer circumference of one end of the movable head 300 close to the cylinder 100. The second sealing ring 320 is provided with a sealing protrusion protruding toward the sealing groove, the sealing protrusion extends along the circumference of the movable head 300, and the sealing protrusion is detachably engaged in the sealing groove.

In some embodiments, the second reinforcing ring 330 can be attached to the outer wall of the movable head 300 and the second sealing ring 320 and welded.

[0072] See also Figure 2 , Figure 4 , Figure 6 , Figure 7 and Fig.10 In this embodiment, the liquid storage tank further includes a driving member 510. The driving member 510 is disposed between the cylinder 100 and the movable head 300 so as to drive the movable head 300 to switch between a closed state and an open state.

[0074] In some embodiments, the driving member 510 may include a cylinder 511 and a piston rod 512. The cylinder 511 is rotatably connected to the movable head 300. One end of the piston rod 512 is telescopically located in the cylinder 511, and the other end of the piston rod 512 is rotatably connected to the cylinder 100. The relative movement of the piston rod 512 and the cylinder 511 enables the movable head 300 to move closer to or farther from the cylinder 100.

[0075] When the piston rod 512 is retracted in the cylinder body 511, the movable head 300 can gradually approach the cylinder body 100 and finally cover the cylinder body 100. When the piston rod 512 extends out of the cylinder body 511, the movable head 300 can gradually move away from the cylinder body 100 to open the second end of the cylinder body 100.

[0076] See also Figure 2 , Figure 4 , Figure 6 , Figure 7 and Fig.10 In some embodiments, the cylinder 511 of the driving member 510 is connected to the movable head 300 so as to avoid other structures on the cylinder 100 , facilitate the installation and movement of the cylinder 511 , and improve the reliability and stability of the driving member 510 .

A second support seat 522 is provided on the movable head 300, and the cylinder 511 is rotatably connected to the second support seat 522. The rotation axis of the piston rod 512 extends horizontally, and the rotation axis of the piston rod 512 is arranged parallel to the rotation axis of the cylinder 511, so that when the piston rod 512 extends out of the cylinder 511, the lower end of the movable head 300 can rotate around the axis of the rotating shaft portion 132 away from the cylinder 100 at a large angle, thereby opening the liquid storage tank and facilitating the discharge of the liquid in the sealed space 400.

[0078] See also Figure 2 , Figure 4 , Figure 7 and Fig.10 In this embodiment, a first support shaft 5211 is provided on the first support seat 521, and one end of the piston rod 512 away from the cylinder body 511 is rotatably sleeved on the first support shaft 5211.

[0079] When the cylinder body 511 and the piston rod 512 are telescopically moved, the first support shaft 5211 and the second support shaft 5111 are relatively far apart, and the first support shaft 5211 can rotate relative to the first support seat 521, and the second support shaft 5111 can rotate relative to the second support seat 522, thereby enabling the movable head 300 to switch between a closed state and an open state.

[0080] In some embodiments, the first support seat 521 can be welded to the cylinder 100 to improve the connection strength and reliability between the first support seat 521 and the cylinder 100. In other embodiments, in the axial direction of the cylinder 100, a first reinforcing ring 110 is provided on one side of the first sealing ring 150 close to the center of the cylinder 100.

The two driving members 510 are disposed on opposite sides of the upper portion of the cylinder 100, and the rotation axes of the piston rods 512 of the two driving members 510 are coaxially arranged, so that the two driving members 510 can simultaneously drive the movable head 300 to switch between the closed state and the open state, thereby improving work efficiency and ensuring the safety and stability of the liquid storage tank.

[0083] In some embodiments, the driving member 510 may also be an electric push rod or other structure, so that the movable head 300 can be switched between the closed state and the open state. In other embodiments, the driving member 510 may also be a driving motor, which can drive the connecting portion 310 to rotate around the rotating shaft portion 132 and can also drive the sliding portion 131 to translate relative to the fixed seat 120, so that the movable head 300 can be switched between the closed state and the open state.

[0084] In some embodiments, both driving members 510 are located at the upper portion of the cylinder 100 , so that when the liquid storage tank discharges liquid waste, the driving members 510 can be kept away from the liquid waste to prevent the liquid waste from contaminating and corroding the driving members 510 .

[0085] See also Figure 5 In this embodiment, a plurality of first locking seats (not shown in the figure) are arranged at intervals along the circumference of the cylinder 100 at the outer periphery of the second end of the cylinder 100. A plurality of second locking seats (not shown in the figure) are arranged at the outer periphery of the movable head 300 relative to the first locking seats. When the movable head 300 is in a closed state, part of the second locking seat is detachably connected to the first locking seat, thereby ensuring the stability of the connection between the cylinder 100 and the movable head 300, preventing the head from being away from the cylinder 100 under the impact of external force, preventing liquid waste from leaking, and improving the safety and reliability of the liquid storage tank.

[0086] See also Figure 2 , Figure 4 and Fig.10 In some embodiments, a locking groove (not shown in the figure) is provided on the first locking seat. An insert tongue (not shown in the figure) is provided on the second locking seat relative to the locking groove. When the movable sealing head 300 is in a closed state, the insert tongue is inserted into the locking groove and is mutually limited with the first locking seat to lock the movable sealing head 300 and the cylinder 100.

[0087] In other embodiments, in the circumferential direction of the cylinder 100, the length of the locking groove is greater than the length of the insertion tongue, so that when the movable head 300 approaches or moves away from the cylinder 100, the insertion tongue can extend into or out of the locking groove, thereby improving the working efficiency of the first locking seat and the second locking seat.

[0088] See also Figure 5 In this embodiment, a plurality of first locking seats are symmetrically arranged along the central plane where the axis of the cylinder 100 is located, and the central plane extends up and down. The central plane extends along the axis of the cylinder 100 and in the up and down direction; it can be understood that the central plane extends in a direction perpendicular to the left and right direction.

[0089] See also Figures 5 to 10 In this embodiment, six first locking seats are provided on the cylinder 100 .

[0090] The two first locking seats are respectively arranged on the left and right sides of the upper part of the cylinder 100, and are located between the first support seat 521 and the fixed seat 120, so that the first locking seat can avoid the fixed seat 120 and the first support seat 521, so as to improve the space utilization rate of the periphery of the liquid storage tank, and also ensure the connection strength and reliability of the movable head 300 and the cylinder 100.

[0091] The four first locking seats are respectively arranged along the left and right sides of the lower part of the cylinder 100 , and the four first locking seats are arranged at intervals along the circumference of the cylinder 100 .

[0093] In other embodiments, seven, eight, nine or ten first locking seats may be provided on the cylinder 100 so as to tightly limit the movable head 300 on the head.

[0094] In some embodiments, the first locking seat may be welded to the first sealing ring 150 and / or the first reinforcement ring 110 adjacent to the first sealing ring 150 to ensure the bearing capacity and reliability of the first locking seat.

[0095] In some embodiments, the second locking seat may be welded to the second sealing ring 320 and / or the second reinforcement ring 330 to ensure the bearing capacity and reliability of the second locking seat.

[0096] See also Figure 2 , Figure 4 , Figure 7 and Fig.10 In this embodiment, a locking member (not shown) is further provided on the first locking seat. The locking member can be inserted into the first locking seat to pass through the locking groove. When the movable sealing head 300 is in a closed state, the plug tongue is inserted into the locking groove, the locking member is inserted into the first locking seat, and passes through the plug tongue to limit the plug tongue in the first locking seat, thereby locking the movable sealing head 300 and the cylinder 100.

[0097] In other embodiments, the locking member may be a hydraulic cylinder or a gas cylinder. The cylinder body 511 of the locking member is fixedly connected to the first sealing ring 150, the first reinforcing ring 110 adjacent to the first sealing ring 150, and / or the first locking seat. The telescopic end of the locking member can move toward the first locking seat to pass through the first locking seat, so that the tongue can be limited in the locking groove to ensure the stability of the connection between the cylinder 100 and the movable head 300.

[0098] In other embodiments, the locking member may also be a structure such as a latch, a mortise and tenon, a bolt, etc., so as to limit the insertion tongue in the first locking seat.

[0099] See also Figure 2 , Figure 4 and Fig.10 In this embodiment, a reinforcing beam 160 is further provided on the cylinder 100. The reinforcing beam 160 extends along the axial direction of the cylinder 100. The reinforcing beam 160 is provided corresponding to the first locking seat. The reinforcing beam 160 is closely attached to and fixed to the outer periphery of the cylinder 100, and one end of the reinforcing beam 160 is connected to the first locking seat to improve the connection strength and reliability between the first locking seat and the cylinder 100.

[0100] In other embodiments, the reinforcing beam 160 may be a triangular structure formed by combining a plurality of beam structures to improve the structural strength and bearing capacity of the reinforcing beam 160 .

[0101] In other embodiments, the reinforcing beam 160 and the first locking seat are integrally formed, thereby improving the structural strength and stability of the first locking seat.

[0102] The above embodiments are merely illustrative descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in the multiple embodiments can be used in any combination. For example, the reinforcing beam 160 can also be directly arranged on one side of the first support seat 521 to improve the structural strength of the connection between the first support seat 521 and the cylinder 100.

[0103] In this embodiment, an oil circuit assembly (not shown) is further provided on the cylinder 100. The oil circuit assembly can be connected to the driving member 510 and the locking member to control the extension and retraction of the driving member 510 and the locking member.

[0104] See also Figures 1 to 10When the liquid storage tank is in use, the piston rod 512 is retracted in the cylinder 511 of the driving member 510, the movable head 300 follows the sliding member 130 to move close to the cylinder 100, and the movable head 300 rotates around the rotating shaft portion 132 toward the second end of the cylinder 100, so that the sealing protrusion can extend into the sealing groove and press on the sealing ring, so that the fixed head 200, the cylinder 100 and the movable head 300 are sealed to form a sealed space 400. After the liquid waste is input into the sealed space 400, the liquid storage tank is transported to the destination.

[0105] After the liquid storage tank is transported to the destination, the piston rod 512 extends out of the cylinder body 511 of the driving member 510, the movable head 300 follows the sliding member 130 to move away from the cylinder body 100, the sealing protrusion disengages from the sealing groove, and the movable head 300 rotates around the rotating shaft portion 132 away from the second end of the cylinder body 100, thereby opening the second end of the cylinder body 100, and the liquid waste in the sealed space 400 is quickly discharged through the second end of the cylinder body 100, thereby effectively improving the transportation efficiency of the waste liquid and reducing labor costs and time costs.

[0106] See also Figures 1 to 10 The present application also provides a tank container, which includes: any of the above liquid storage tanks and a frame 40. The frame 40 is arranged on the outside of the liquid storage tank to be fixedly connected to the outer peripheral wall of the liquid storage tank to protect the liquid storage tank, facilitate the transportation and connection of the tank container, and improve the safety and reliability of the tank container.

[0107] In some embodiments, the second end of the liquid storage tank is located outside the frame 40 to prevent the liquid waste from being contaminated on the frame 40 when the liquid storage tank discharges the liquid waste, to prevent the frame 40 from being corroded, and to extend the service life of the tank container.

[0108] In some embodiments, the frame 40 is sleeved on the outer circumference of the cylinder 100, and the frame 40 is welded to the outer circumferential wall of the cylinder 100 to ensure the structural strength and reliability of the frame 40 and the liquid storage tank.

[0109] In other embodiments, the structure of the frame 40 may refer to the structure of the frame 40 of a related tank container to protect and limit the liquid storage tank.

[0110] The present application also provides a tank truck, which includes: a vehicle body (not shown in the figure) and a tank container as described above. The tank container is connected to the vehicle body so that the tank container can move with the vehicle body to improve the transportation efficiency of liquid waste and reduce the transportation cost of liquid waste.
