DETAILED DESCRIPTION

[0022] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0023] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0024] See also Figure 1 and Figure 2 An embodiment of the present application provides a bottom valve remote control device 10, which is mainly used in a tank container to realize the opening and closing of a bottom valve 20 on the tank container. In this embodiment, the bottom valve remote control device 10 includes a linkage member 11 and a remote control member 12.

[0025] Specifically, one end of the linkage member 11 is used to connect with the bottom valve 20 to drive the driving shaft 21 of the bottom valve 20 to rotate around its own axis. The remote control member 12 includes a remote control handle 121 and a driving connecting rod 122, the driving connecting rod 122 is connected to the other end of the linkage member 11, and the remote control handle 121 is rotatably connected to the end of the driving connecting rod 122 away from the linkage member 11, and the rotation axis of the remote control handle 121 is colinear with the axis of the driving connecting rod 122.

[0026] The remote control handle 121 rotates to drive the driving connecting rod 122 to rotate, so as to drive the linkage member 11 to rotate, thereby driving the driving shaft 21 of the bottom valve 20 to rotate, so that the bottom valve 20 is opened or closed.

[0027] Furthermore, the linkage member 11 of this embodiment includes a sleeve joint 111 and a transfer connecting rod 112. The sleeve joint 111 is open at both ends and hollow inside. One end of the transfer connecting rod 112 is fixed inside the end of the sleeve joint 111, and the other end is connected to the driving connecting rod 122.

[0028] In this embodiment, the bottom valve 20 connected to the linkage 11 further includes a handle 22. The handle 22 is perpendicularly connected to the drive shaft 21 of the bottom valve 20. When the handle 22 rotates, the drive shaft 21 can rotate about its own axis to open or close the bottom valve 20.

[0029] As Figure 3 shown, a clamping interface 114 is provided on the side wall of the end of the sleeve joint 111 away from the adapter rod, and the handle 22 of the bottom valve 20 is clamped in the clamping interface 114. After the sleeve joint 111 is fixedly clamped with the handle 22, the axis of the sleeve joint 111 is parallel to the axis of the drive shaft 21.

[0030] When the sleeve joint 111 rotates under the drive of the adapter connecting rod 112, the sleeve joint 111 will drive the handle 22 clamped thereto to rotate about the axis of the sleeve joint 111. Since the handle 22 is connected to the drive shaft 21 of the bottom valve 20, the rotation of the handle 22 will drive the drive shaft 21 to rotate about its own axis, thereby realizing the opening and closing of the bottom valve 20.

[0031] Refer to Figure 4 , in addition to the structure of the sleeve joint 111 shown above, in other embodiments, the sleeve joint 111 can also be set to a structure with one end open and a shaft hole 115 provided on the end face of the other end. When the bottom valve 20 cooperates with the bottom valve remote control device 10 of this structure, the handle 22 can be omitted on the bottom valve 20.

[0032] Wherein, one end of the adapter connecting rod 112 is coaxially fixed in the open end of the sleeve joint 111, and the other end is connected to the drive connecting rod 122 to transmit the driving force of the drive connecting rod 122 to the sleeve joint 111. The rotation of the drive connecting rod 122 will drive the connected adapter connecting rod 112 to rotate to drive the sleeve joint 111 to rotate.

[0033] The shaft hole 115 provided on the end face of the sleeve joint 111 is adapted to the outer peripheral shape of the drive shaft 21, and the drive shaft 21 of the bottom valve 20 is fixedly inserted through the shaft hole 115 on the end face of the sleeve joint 111. In this embodiment, the shape of the shaft hole 115 can be an irregular or regular shape, and can be in the shape of a cam, gear, square, polygon, etc., which will not be listed one by one here, as long as it can ensure that the sleeve joint 111 rotates to drive the drive shaft 21 to rotate.

[0034] When the sleeve joint 111 rotates under the drive of the adapter connecting rod 112, the sleeve joint 111 will directly drive the connected drive shaft 21 to rotate, so that the drive shaft 21 rotates about its own axis, thereby realizing the opening and closing of the bottom valve 20.

[0035] The sleeve joint 111 and the adapter link 112 can be connected by fasteners or directly fixed by welding. The fasteners can be pin shafts or bolts. In addition, the sleeve joint 111 and the adapter link 112 can also be integrally formed, that is, the linkage member 11 is of an integrally formed structure. Setting the linkage member 11 as an integrally formed structure can facilitate the assembly of the linkage member 11 and the remote control member 12, which is beneficial to the overall assembly of the bottom valve remote control device 10.

[0036] Further, one end of the adapter link 112 away from the sleeve joint 111 is connected to the drive link 122. In this embodiment, the bottom valve remote control device 10 further includes a universal coupling 13, and the adapter link 112 and the drive link 122 are connected by the universal coupling 13.

[0037] The adapter link 112, the drive link 122 and the universal coupling 13 can be connected by fasteners or directly fixed by welding. The fasteners can be pin shafts or bolts. Among them, the axis of the drive link 122 and the axis of the adapter link 112 are arranged at a set angle. In this embodiment, the set angle α is 0° to 45°.

[0038] Connecting the adapter link 112 and the drive link 122 by the universal coupling 13 can make the axes of the adapter link 112 and the drive link 122 not on the same straight line, so that there is an axis angle arrangement between the adapter link 112 and the drive link 122. Such a setting can not only make the overall structure of the bottom valve remote control device 10 compact, have a large angular compensation ability and higher transmission efficiency, but also enable the installation of the segmented inclination angle between the drive link 122 and the adapter link 112, with stronger installation flexibility. It will not be limited to the narrow space near the bottom valve 20, and the position of the drive link 122 can be correspondingly raised or turned, so as to raise or turn the position of the remote control handle 121, realizing the flexible arrangement of the installation position of the remote control handle 121, thus facilitating the operation of the staff.

[0039] In this embodiment, the remote control handle 121 is connected to the end of the drive link 122 away from the adapter link 112. The rotation axis of the remote control handle 121 is collinear with the axis of the drive link 122. Operating the rotation of the remote control handle 121 can drive the drive link 122 to rotate around its own axis, thereby driving the adapter link 112 and the sleeve joint 111 to rotate.

[0040] The remote control handle 121 and the drive link 122 in this embodiment can be integrally formed, that is, the remote control member 12 is of an integrally formed structure. Such a setting can facilitate the assembly of the remote control member 12 and the linkage member 11, which is beneficial to the overall assembly of the bottom valve remote control device 10.

[0041] Such as Figure 5As shown, in this embodiment, the bottom valve remote control device 10 further includes a secondary remote control member 14, and the secondary remote control member 14 is connected to the remote control handle 121. The length of the secondary remote control member 14 can be set according to the need of the remote control distance to achieve remote control over a longer distance, so as to switch the bottom valve 20 on or off at a distance and make the control of the bottom valve 20 more flexible.

[0042] The secondary remote control member 14 in this embodiment can be a flexible structure such as a steel wire rope, or a rigid structure such as a secondary connecting rod or a secondary handle. There is no excessive limitation here, as long as it can ensure that under the condition of a set distance, the secondary remote control member 14 can control the rotation of the remote control handle 121, thereby achieving remote control over a long distance.

[0043] When the secondary remote control member 14 pulls the remote control handle 121 to rotate, the remote control handle drives the drive link 122 to rotate. The drive link 122 and the transfer link 112 are connected by a universal coupling 13. Even if the drive link 122 and the transfer link 112 are not coaxially arranged, the rotation of the drive link 122 will still drive the connected transfer link 112 to rotate, so that the socket joint 111 fixed to the transfer link 112 rotates. Since the socket joint 111 is connected to the handle 22 of the bottom valve 20 or the drive shaft 21 of the bottom valve 20, the rotating socket joint 111 will drive the drive shaft 21 to move, causing the drive shaft 21 to rotate around its own axis to open or close the bottom valve 20.

[0044] This application also provides a tank body, and a bottom valve 20 is provided near the bottom of the tank body. The above-mentioned bottom valve remote control device 10 is also provided on the tank body, and the linkage member 11 in the bottom valve remote control device 10 is connected to the bottom valve 20 to drive the drive shaft 21 of the bottom valve 20 to rotate around its own axis.

[0045] When it is necessary to open or close the bottom valve 20, it can be achieved by rotating the remote control handle 121. When the remote control handle 121 rotates, the rotational driving force will be transmitted to the socket joint 111 through the drive link 122 and the transfer link 112, so that the socket joint 111 drives the drive shaft 21 of the bottom valve 20 to rotate, thereby opening or closing the bottom valve 20.

[0046] In addition, this application also provides a tank container, and the tank container includes a frame and the above-mentioned tank body, and the tank body is supported by the frame.

[0047] For the foot valve remote control device, the tank body, and the tank container of the present application, when the remote control handle is rotated, the remote control handle drives the driving link to rotate, so as to drive the linkage to rotate, thereby driving the driving shaft of the foot valve connected to the linkage to rotate, so as to open or close the foot valve. The overall structure of the foot valve remote control device is compact, with high transmission efficiency, and can convert the drive of the foot valve into a rotational drive without a linear drive stroke, without being limited by the narrow installation space near the foot valve at the bottom of the tank body, and can realize flexible arrangement of the installation position of the remote control handle, thus facilitating the operation of the staff.

[0048] Although the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be construed 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.
