[0037] See Figures 1 to 8 This application provides a liquid storage tank, comprising: a cylindrical body 100, a fixed end cap 200, and a movable end cap 300. The cylindrical body 100 extends horizontally. The cylindrical body 100 includes a first end and a second end. A fixed seat 120 is protruding from the top surface of the second end of the cylindrical body 100, and a sliding member 130 is provided on the fixed seat 120. The sliding member 130 is movable relative to the fixed seat 120 along the axial direction of the cylindrical body 100. In the axial direction of the cylindrical body 100, the sliding member 130 can extend beyond the outer side of the cylindrical body 100. The fixed end cap 200 is fixed to the first end of the cylindrical body 100 for a sealing connection with the cylindrical body 100. The movable end cap 300 is rotatably connected to the sliding member 130, and the movable end cap 300 can follow the sliding member 130 to move along the axial direction of the cylindrical body 100, so that the movable end cap 300 can be opened and closed to cover the second end of the cylindrical body 100. The movable end cap 300 has a closed state and an open state. When the movable end cap 300 is in the closed state, the movable end cap 300, the fixed end cap 200, and the cylinder 100 enclose a sealed space 400 for containing liquid. When the movable end cap 300 is in the open state, the movable end cap 300 moves 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 transferred and processed, the movable end cap 300 rotates around the sliding member 130, and both the movable end cap 300 and the sliding member 130 move along the axis of the cylinder 100 toward the center of the cylinder 100, so that the movable end cap 300 covers the second end of the cylinder 100, the movable end cap 300 switches to the closed state, and the movable end cap 300, the cylinder 100 and the fixed end cap 200 enclose and form a sealed space 400.

[0039] After the liquid waste is fed into the sealed space of 400, the staff can transport the liquid waste by transferring it to a liquid storage tank.

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

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

[0042] In some embodiments, the cylinder 100 may be provided with a liquid inlet hole so that external liquid waste can enter the sealed space 400 through the liquid inlet hole.

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

[0044] See Figure 1 and Figure 3 In this embodiment, a plurality of first reinforcing rings 110 are also fitted around the outer periphery of the cylinder 100. The plurality of first reinforcing rings 110 are arranged at intervals along the axial direction of the cylinder 100. The first reinforcing rings 110 extend circumferentially along the cylinder 100 to enhance the structural strength of the cylinder 100 and ensure the reliability of the liquid storage tank.

[0045] Figure 9 This is a structural schematic diagram of the tank container when the liquid storage tank of this application is in the open state. Figure 10 yes Figure 9 Enlarged view of the structure at point E in the middle.

[0046] See Figures 1 to 6 , Figure 9 and Figure 10In this embodiment, a fixed seat 120 is provided on the top of the second end of the cylinder 100. A sliding member 130 is provided on the fixed seat 120, and the sliding member 130 can move relative to the fixed seat 120 along the axial direction of the cylinder 100.

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

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

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

[0050] The sliding member 130 may include a sliding part 131 and a rotating shaft part 132. The sliding part 131 is slidably inserted into the fixed base 120 in the front-back direction. The rotating shaft part 132 is located at the end of the sliding part 131 away from the center of the cylinder 100. The rotating shaft part 132 is used to rotatably connect with the movable end cap 300.

[0051] In other embodiments, the pivot portions 132 of the two sliding members 130 are coaxially arranged, and the axes of the two pivot portions 132 extend in the left-right direction. When the movable end cap 300 is rotatably connected to the two pivot portions 132, the movable end cap 300 can not only move back and forth with the sliding part 131 relative to the fixed base 120, but also rotate around the axis of the pivot portion 132, thereby allowing the movable end cap 300 to switch between a closed state and an open state.

[0052] In some embodiments, the pivot portion 132 can be moved in the axial direction of the cylinder 100 and a portion of the pivot portion 132 extends to the outside of the cylinder 100, so that the rotation axis of the movable end cap 300 can be located outside the cylinder 100, which facilitates the rotation of the movable end cap 300 around the pivot portion 132 and ensures the ease of connection and disassembly of the movable end cap 300 and the cylinder 100.

[0053] In some embodiments, a limiting member 140 may be provided on the fixed base 120. The limiting member 140 may abut against 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 dislodging from the fixed base 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, the limiting member 140 can pass through one end of the sliding shaft near the center of the cylinder 100. The limiting member 140 can abut against and limit the fixing seat 120 to prevent the sliding member 130 from falling out of the fixing seat 120, thereby ensuring the safety and reliability of the liquid storage tank.

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

[0056] See Figure 2 , Figure 4 and Figure 10 In this embodiment, a first sealing ring 150 is sleeved on the outer periphery of the second end of the cylinder 100, and the first sealing ring 150 fits tightly against the outer periphery of the cylinder 100. The first sealing ring 150 can be used to seal with the movable end cap 300, thereby ensuring the sealing performance between the cylinder 100 and the movable end cap 300 and preventing liquid leakage from the gap between the cylinder 100 and the movable end cap 300.

[0057] In some embodiments, the first sealing ring 150 has a sealing groove recessed on one end face facing the movable head 300, and the sealing groove extends circumferentially along 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, thereby ensuring 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 end cap 300.

[0060] See Figure 1 , Figure 3 and Figure 9 In this embodiment, the fixed end cap 200 is fixedly connected to the cylinder 100 so as to form a sealed space 400.

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

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

[0063] When the movable end cap 300 moves to the closed state, the movable end cap 300 rotates around the axis of the rotating shaft 132 toward the second end of the cylinder 100, and the movable end cap 300 moves toward the center of the cylinder 100 along with the sliding part 131, so that the movable end cap 300 covers the cylinder 100 and the movable end cap 300 is in a sealed connection with the cylinder 100.

[0064] When the movable end cap 300 switches from the closed state to the open state, the movable end cap 300 rotates around the axis of the rotating shaft 132 away from the second end of the cylinder 100, and the movable end cap 300 moves away from the center of the cylinder 100 along with the sliding part 131, so that the movable end cap 300 separates from the cylinder 100, and the second end of the cylinder 100 opens, thereby facilitating the discharge of liquid in the sealed space 400.

[0065] See Figure 2 , Figure 4 , Figure 6 and Figure 10 In this embodiment, the top of the movable end cap 300 is provided with a connecting portion 310 protruding upward. The connecting portion 310 is rotatably connected to the rotating shaft portion 132, so that the connecting portion 310 and the movable end cap 300 can rotate around the rotating shaft portion 132, thereby realizing the state switching of the movable end cap 300.

[0066] In some embodiments, the top of the movable end cap 300 is provided with two connecting portions 310 corresponding to the sliding member 130. The two connecting portions 310 are arranged at intervals in the left-right direction. The two connecting portions 310 can be respectively sleeved on the opposite ends of the rotating shaft portion 132, so that the two connecting portions 310 can rotate around the rotating shaft portion 132.

[0067] In other embodiments, the two connecting portions 310 are located at the left and right ends of the rotating shaft portion 132, respectively. A fixed shaft 311 is detachably provided on the connecting portion 310. The fixed shaft 311 extends in the left and right direction and can pass through the two connecting portions 310 and the rotating shaft portion 132 to realize the rotational connection between the connecting portion 310 and the rotating shaft portion 132.

[0068] See Figure 2 , Figure 4 , Figure 6 and Figure 10 In this embodiment, a second sealing ring 320 is fitted around the outer periphery of the movable end cap 300 near the cylinder 100. The second sealing ring 320 has a sealing protrusion protruding towards the sealing groove. The sealing protrusion extends circumferentially along the movable end cap 300 and is detachably engaged in the sealing groove.

[0069] When the movable head 300 is in the closed state, the sealing protrusion can penetrate into the sealing groove and press against the sealing ring, thereby ensuring the sealing performance between the cylinder 100 and the movable head 300.

[0070] In some embodiments, the second sealing ring 320 can be integrally formed with the movable head 300, thereby ensuring the reliability and stability of the movable head 300.

[0071] See Figure 2 , Figure 4 , Figure 6 and Figure 10 In this embodiment, a second reinforcing ring 330 is provided on the side of the second sealing ring 320 opposite to the cylinder 100 along the axial direction of the cylinder 100. The second reinforcing ring 330 improves the reliability and stability of the movable head 300 and ensures the structural strength and stability of the second sealing ring 320. In some embodiments, the second reinforcing ring 330 can be fitted and welded to the outer wall of the movable head 300 and the second sealing ring 320.

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

[0073] In some embodiments, the drive element 510 may be a hydraulic cylinder or a pneumatic cylinder.

[0074] In some embodiments, the drive 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 retractably located within 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 allows the movable head 300 to move closer to or further away from the cylinder 100.

[0075] When the piston rod 512 retracts into the cylinder 511, it allows the movable end cap 300 to gradually approach the cylinder 100 and eventually close onto the cylinder 100. When the piston rod 512 extends out of the cylinder 511, it allows the movable end cap 300 to gradually move away from the cylinder 100, thereby opening the second end of the cylinder 100.

[0076] See Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 10 In some embodiments, the cylinder 511 of the drive component 510 is connected to the movable end cap 300 to avoid other structures on the cylinder 100, which facilitates the installation and movement of the cylinder 511 and improves the reliability and stability of the drive component 510.

[0077] A first support seat 521 is provided on the second end of the cylinder 100, and the piston rod 512 is rotatably connected to the first support seat 521. 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 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 at a large angle away from the cylinder 100 around the axis of the rotating shaft 132, thereby opening the liquid storage tank and facilitating the discharge of liquid in the sealed space 400.

[0078] See Figure 2 , Figure 4 , Figure 7 and Figure 10 In this embodiment, a first support shaft 5211 is provided on the first support base 521, and the end of the piston rod 512 away from the cylinder body 511 is rotatably sleeved on the first support shaft 5211. A second support shaft 5111 protrudes from the cylinder body 511 and is rotatably inserted through the second support base 522. The axes of the first support shaft 5211 and the second support shaft 5111 are parallel.

[0079] When the cylinder 511 and piston rod 512 extend and retract, the first support shaft 5211 and the second support shaft 5111 move away from each other, 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 allowing the movable end cap 300 to switch between a closed state and an open state.

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

[0081] In some embodiments, the second support base 522 can be welded to the outer peripheral wall of the second sealing ring 320 and the movable end cap 300, thereby improving the connection strength and reliability between the second support base 522 and the movable end cap 300 and the second sealing ring 320. In other embodiments, the second support base 522 can be welded to the second sealing ring 320, the second reinforcing ring 330 and the movable end cap 300, to improve the support capacity and reliability of the second support base 522.

[0082] See Figure 3, Figure 5 and Figure 7 In this embodiment, the liquid storage tank includes two driving components 510. The two driving components 510 are respectively disposed on opposite sides of the upper part of the cylinder 100. The rotation axes of the piston rods 512 of the two driving components 510 are coaxially arranged, so that the two driving components 510 can simultaneously drive the movable end cap 300 to switch between the closed state and the open state, thereby improving working efficiency and ensuring the safety and stability of the liquid storage tank.

[0083] In some embodiments, the drive element 510 may also be an electric push rod or similar structure, so that the movable end cap 300 can switch between a closed state and an open state. In other embodiments, the drive element 510 may also be a drive motor, which can drive the connecting part 310 to rotate around the rotating shaft 132 and drive the sliding part 131 to translate relative to the fixed base 120, thereby enabling the movable end cap 300 to switch between a closed state and an open state.

[0084] In some embodiments, both drive members 510 are located at the upper part of the cylinder 100, so that when the liquid storage tank discharges liquid waste, the drive members 510 can be kept away from the liquid waste, preventing the liquid waste from contaminating or corroding the drive members 510.

[0085] See Figure 5 In this embodiment, a plurality of first locking seats (not shown in the figure) are provided on the outer periphery of the second end of the cylinder 100, and the plurality of first locking seats are arranged at intervals along the circumference of the cylinder 100. A plurality of second locking seats (not shown in the figure) are provided on the outer periphery of the movable end cap 300 relative to the first locking seats. When the movable end cap 300 is in the closed state, a portion 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 end cap 300, preventing the end cap from moving away from the cylinder 100 under external impact, preventing liquid waste leakage, and improving the safety and reliability of the liquid storage tank.

[0086] See Figure 2 , Figure 4 and Figure 10 In some embodiments, the first locking seat has a locking groove (not shown in the figure). The second locking seat has a tongue protruding from the locking groove (not shown in the figure). When the movable end cap 300 is in the closed state, the tongue is inserted into the locking groove and mutually limits the first locking seat to lock the movable end cap 300 and the cylinder 100.

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

[0088] See Figure 5 In this embodiment, multiple first locking seats are symmetrically arranged along the central plane containing the axis of the cylinder 100, and the central plane extends vertically. The central plane extends both along the axis of the cylinder 100 and in the vertical direction; it can be understood that the central plane extends in a direction perpendicular to the left and right direction.

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

[0090] Two first locking seats are respectively disposed 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 seats can avoid the fixed seat 120 and the first support seat 521, thereby improving the space utilization rate of the outer periphery of the liquid storage tank, and also ensuring the connection strength and reliability of the movable end cap 300 and the cylinder 100.

[0091] The four first locking seats are respectively located on 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.

[0092] In some embodiments, the included angle between any two adjacent first locking seats in the plurality of first locking seats located at the lower part of the cylinder 100 is equal, so as to improve the load-bearing capacity at various points at the lower part of the movable head 300 and facilitate the locking and sealing of the movable head 300 and the cylinder 100.

[0093] In other embodiments, the cylinder 100 may be provided with seven, eight, nine, or ten first locking seats to securely confine the movable end cap 300 to the end cap.

[0094] In some embodiments, the first locking seat may be welded to the first sealing ring 150 and / or the first reinforcing ring 110 adjacent to the first sealing ring 150 to ensure the load-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 reinforcing ring 330 to ensure the load-bearing capacity and reliability of the second locking seat.

[0096] See Figure 2 , Figure 4 , Figure 7 and Figure 10 In this embodiment, a locking member (not shown in the figure) is also 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 end cap 300 is in the closed state, the tongue is inserted into the locking groove, the locking member is inserted into the first locking seat and passes through the tongue to limit the tongue within the first locking seat, thereby locking the movable end cap 300 and the cylinder 100.

[0097] In other embodiments, the locking element can be a hydraulic cylinder or a pneumatic cylinder. The cylinder body 511 of the locking element 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 element can move toward the first locking seat to pass through the first locking seat, thereby confining the tongue within the locking groove and ensuring the stability of the connection between the cylinder 100 and the movable end cap 300.

[0098] In other embodiments, the locking element may also be a pin, tenon, bolt, or other structure, as long as it can confine the tongue within the first locking seat.

[0099] See Figure 2 , Figure 4 and Figure 10 In this embodiment, a reinforcing beam 160 is also provided on the cylinder 100. The reinforcing beam 160 extends axially along the cylinder 100. The reinforcing beam 160 is provided corresponding to the first locking seat. The reinforcing beam 160 is tightly fitted 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 can be a triangular structure formed by combining multiple beam structures to improve the structural strength and load-bearing capacity of the reinforcing beam 160.

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

[0102] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used. For example, the reinforcing beam 160 can also be directly set on one side of the first support 521 to improve the structural strength of the connection between the first support 521 and the cylinder 100.

[0103] In this embodiment, an oil circuit assembly (not shown in the figure) is also provided on the cylinder 100. The oil circuit assembly can communicate with the drive member 510 and the locking member to control the extension and retraction of the drive member 510 and the locking member.

[0104] See Figures 1 to 10When the liquid storage tank is in use, the piston rod 512 retracts into the cylinder 511 of the drive member 510. The movable end cap 300 moves closer to the cylinder 100 following the sliding member 130, and the movable end cap 300 rotates around the rotating shaft 132 toward the second end of the cylinder 100, so that the sealing protrusion can extend into the sealing groove and press against the sealing ring, thereby forming a sealed space 400 by the fixed end cap 200, the cylinder 100, and the movable end cap 300. After the liquid waste is fed into the sealed space 400, the liquid storage tank is transported to its destination.

[0105] After the liquid storage tank is transported to its destination, the piston rod 512 extends out of the cylinder 511 of the drive component 510, and the movable end cap 300 moves away from the cylinder 100 along with the sliding component 130. The sealing protrusion disengages from the sealing groove, and the movable end cap 300 rotates around the second end of the rotating shaft 132 away from the cylinder 100, thereby opening the second end of the cylinder 100. The liquid waste in the sealed space 400 is quickly discharged through the second end of the cylinder 100, thereby effectively improving the transfer efficiency of waste liquid and reducing labor and time costs.

[0106] See Figures 1 to 10 This application also provides a tank container, which includes: any of the above-mentioned liquid storage tanks and a frame 40. The frame 40 is disposed on the outside of the liquid storage tank to be fixedly connected to the outer peripheral wall of the liquid storage tank, so as to protect the liquid storage tank and facilitate the transportation and connection of the tank container, thereby improving 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 liquid waste from contaminating the frame 40 when the liquid storage tank discharges liquid waste, thus preventing the frame 40 from being corroded and extending the service life of the tank container.

[0108] In some embodiments, the frame 40 is sleeved on the outer periphery of the cylinder 100 and welded to the outer peripheral 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 frame 40 structure may refer to the frame 40 structure of a relevant tank container to protect and limit the liquid storage tank.

[0110] This 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, thereby improving the transportation efficiency of liquid waste and reducing the transportation cost of liquid waste.

[0111] In some embodiments, the tank container includes a frame 40 and a liquid storage tank. The liquid storage tank includes a fixed end cap 200, a cylindrical body 100, and a movable end cap 300. The end of the frame 40 near the movable end cap 300 is rotatably connected to the vehicle body, and the end of the frame 40 near the fixed end cap 200 is vertically connected to the vehicle body.

[0112] When the tanker arrives at its destination to discharge liquid waste, the movable end cap 300 moves away from the cylinder 100 to open the second end of the cylinder 100. Furthermore, the end of the frame 40 near the fixed end cap 200 rises, facilitating the emptying of liquid waste from the cylinder 100, improving drainage efficiency, and reducing liquid residue in the cylinder 100 and the fixed end cap 200.

[0113] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
