Description

Technical Field

[0001] This utility model relates to the technical field of foldable fluid containment devices, specifically a retaining wall structure for a fluid containment device. Background Technology

[0002] Portable, collapsible liquid containment devices are designed to prevent hazardous fluids from spilling into the environment during the loading, unloading, flushing, and repair / maintenance of transport vehicles. Typically, one or more sides of the containment device can be lowered and laid flat to allow easy access to the containment area for equipment or vehicles. Once the equipment or vehicle is inside, the side walls rise to prevent fluid spillage. Any spilled or flushed fluid is retained within the container and can be pumped externally for appropriate treatment. After the container is emptied, the side walls can be lowered again to facilitate the removal of the equipment or vehicle. Furthermore, the container can be folded or rolled up for easy storage and transport.

[0003] The flexible foldable housing device requires a side wall support with a certain strength as a support structure. At the same time, the support structure needs to adapt to the folding of the housing device by quick and easy terrain changes so that wheeled equipment can drive into the housing device and quickly return to the initial position after the wheeled equipment drives in to form support for the folding device.

[0004] A prior art Chinese invention patent (application number 201580071762.3) discloses a foldable fluid containment device with a locking sidewall bracket, including a sidewall support bracket that rotates from a generally horizontal position to an elevated generally vertical position and locks in place. The sidewall bracket can be attached to at least one sidewall of the containment device and supports the sidewall in the fluid containment structure when elevated. The sidewall bracket includes a base support leg, a sidewall support arm rotatably mounted on the support leg, and a locking tab for holding the sidewall support arm in a generally vertical position. This patent's sidewall bracket requires a separate pivot pin connecting the support leg and the support arm, resulting in a complex structure and a lack of deformation-limiting locking for the support arm, posing a risk of tipping over during use. Utility Model Content

[0006] To achieve the above objectives, a baffle structure for a fluid containment device is designed, comprising a base and a baffle rod. The base has a vertical through hole, and the inner wall of the vertical through hole has symmetrically arranged transverse through holes. The baffle rod includes two vertical rods, with a bent section at the end of the vertical rod near the base. The bent section is inserted into the transverse through hole on the base and is rotatably connected. A connecting section is provided on the baffle rod away from the base, and the two ends of the connecting section are respectively connected to the adjacent vertical rods. The vertical rods are made of a metal material with shape memory function, and two limiting blocks are symmetrically arranged at the vertical through hole on the base. A baffle rod gap is formed by the vertical rods and the connecting section. The width of the baffle rod gap changes with the deformation of the vertical rods. A limiting gap is formed between the limiting blocks, which is used to block the undeformed baffle rod and allow the deformed baffle rod to pass through.

[0016] Compared with the prior art, the advantages of this utility model are: By using the combination of the stop lever and the base, the separate rotating pin is eliminated, simplifying the device structure, achieving weight reduction, and reducing the risk of component failure caused by redundant device structures.

Detailed Implementation

[0018] To make the purpose, principle and structure of this utility model clearer, the following description is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] This utility model provides a retaining wall structure for a fluid containing device, such as Figures 1-14 As shown, it mainly includes a base 1 and a stop bar 2.

[0020] The base 1 serves as a support foundation and has a vertical through hole 11. The inner wall of the vertical through hole 11 has symmetrically arranged horizontal through holes 12. The base 1 has two connecting ears 14 opposite to the vertical through holes 11, and the horizontal through holes 12 are symmetrically arranged in the connecting ears 14.

[0021] Two limiting blocks 13 are symmetrically arranged on the inner wall of the connecting ear 14, forming a limiting gap 131 between the two limiting blocks 13; a support block 141 is also provided on the inner wall of the connecting ear 14 away from the limiting blocks 13, and a positioning gap is left between the support block 141 and the limiting blocks 13, forming a positioning notch 142. The support block 141 is a right-angled triangular block structure with thickness and bevel, and its surface near the positioning notch 142 is a vertical plane, used to form a stable abutment with the stop bar 2.

[0022] Furthermore, the base 1 has a bevel 15 at the end away from the vertical through hole 11, with guide sections 16 arranged parallel to each other on both sides. A guide gap 161 is left between the guide sections 16 and the base 1. The end of the guide section 16 near the vertical through hole 11 is fixedly connected to the base 1, and the end away from the vertical through hole 11 has a protrusion 162. The guide section 16 is made of a deformable material. The bevel 15 is used to facilitate insertion into the bag-shaped part on the bottom surface of the fluid receiving device. The guide section 16, the guide gap 161, and the protrusion 162 are used to increase the friction between the base 1 and the bag-shaped part.

[0023] The base 1 is also provided with fixing holes 17, which include a vertically arranged countersunk hole 171 and a through hole 172 located in the countersunk hole 171. The through hole 172 is used for bolts to pass through, and the countersunk hole 171 is used to engage with the bolt nut. Thus, the base 1 can be fixed to the ground by bolts through the fixing holes 17.

[0024] The stop lever 2 includes two vertical rods 21, which are made of a metal material with shape memory function, preferably stainless steel, to ensure that the vertical rods 21 can deform when subjected to external force and return to their original initial state when the external force is removed. A bent section 211 is provided at the end of the vertical rod 21 near the base 1. This bent section 211 is inserted into the transverse through hole 12 of the connecting lug 14 and forms a rotatable connection, allowing the stop lever 2 to rotate around the transverse through hole 12. Preferably, the bent section 211 and the vertical rod 21 form a 90-degree angle relationship, and an arc-shaped transition structure is provided at the connection between the bent section 211 and the vertical rod 21. The bent sections 211 of adjacent vertical rods 21 are coaxially arranged, and the transverse through holes 12 are also coaxially arranged, allowing the stop lever 2 to rotate within the transverse through hole 12 via the bent section 211.

[0025] A connecting section 22 is provided at the end of the stop bar 2 away from the base 1. The two ends of the connecting section 22 are fixedly connected to the adjacent vertical bar 21. A reinforcing plate 24 is also provided on the stop bar 2. The reinforcing plate 24 is located at the position of the stop bar 2 away from the end and is fixedly connected to the adjacent vertical bar 21 to control the degree of deformation of the vertical bar 21. The width of the stop bar gap 23 formed by the vertical bar 21 and the connecting section 22 changes with the deformation of the vertical bar 21. When an external force is applied to the vertical bar 21, due to the rod-like structure of the vertical bar 21, a lever action is formed with the connecting section 22 as the fulcrum, which in turn affects the deformation stroke of the maximum and minimum width of the stop bar gap 23. By providing the reinforcing plate 24 on the stop bar 2, the position of the fulcrum of the lever action can be adjusted, and the length of the lever arm on the vertical bar 21 can be controlled. Thus, without changing the material of the vertical bar 21, the degree of deformation of the vertical bar 21 can be controllably adjusted, thereby controlling the deformation stroke of the maximum and minimum width of the stop bar gap 23.

[0026] In this embodiment, the width of the limiting gap 131 between adjacent limiting blocks 13 is greater than the minimum width of the stop gap 23 and less than the maximum width of the stop gap 23; the inner wall of the limiting block 13 is a curved bending structure 132, the upper part of which is an upper smooth section 1321 close to the opposing limiting block, the middle part is a middle curved bending section 1322 gradually moving away from the opposing limiting block, and the lower part is a lower smooth section 1323 moving away from the opposing limiting block, so that the limiting gap 131 gradually widens from top to bottom along the curved bending section. Preferably, the upper smooth section 1321 and the lower smooth section 1323 can be vertically arranged planes.

[0027] The working principle of this device in the specific working process is as follows.

[0028] In the prior art, the side and bottom connections of the receiving device are provided with bag-shaped parts with a pocket structure, and the base 1 and the stop bar 2 are respectively inserted into the bag-shaped parts of the bottom and the side.

[0029] When the fluid receiving device is placed flat on its side, the stop bar 2 rotates around the transverse through hole 12 to a horizontal position. At this time, the vertical rod 21 of the stop bar 2 can be squeezed in opposite directions. Under the action of the squeezing force, the vertical rod 21 deforms and bends under the action of lever with the connecting section 22 or the reinforcing plate 24 as the fulcrum. The two vertical rods 21 gradually approach each other at the end near the transverse through hole 12. At this time, the stop bar gap 23 reaches the minimum width due to the deformation of the vertical rod 21, and can pass smoothly through the limiting gap 131. At this time, the stop bar 2 and the limiting block 13 form a clearance. The stop bar 2 can be folded down smoothly without creating a limiting block between it and the limiting block 13. The stop bar 2 can rotate freely, and the squeezing force applied to the stop bar 2 will accumulate in the form of material elastic potential energy. The curved bending structure 132 of the limiting block 13 acts as a guide. The vertical rod 21 of the originally vertical stop bar 2 is locked in the positioning notch 142 between the limiting block 13 and the support block 141. Under the action of downward pressing and inward squeezing force, the stop bar 2 can be folded down along the curved structure of the limiting block 13 under the smooth transition of the curved surface. The stop bar 2 can first be locked in the upper smooth section 1321 under the action of squeezing deformation, then slide along the curved surface to the middle curved bending section 1322, and finally fall into the lower smooth section 1323.

[0030] When the stop lever 2 rotates from the upright position to the flat position, the opening angle between the stop lever 2 and the base 1 changes from 90 degrees to 0 degrees until the stop lever 2 and the base 1 are in contact and folded into place. At this time, the force applied to the stop lever 2 is removed, the elastic potential energy is released, and the vertical rod 21 returns to its initial shape due to the shape memory function of the material. The two vertical rods 21 of the stop lever 2 are spread open to both sides and abut against the lower smooth section 1323 of the curved bending structure 132 of the limiting block 13 again. The upper side of the end of the vertical rod 21 is blocked and limited by the middle curved bending section of the curved bending structure 132, ensuring that the flat vertical rod 21 will not be easily lifted by external force, so that the side and bottom of the receiving device form a stable fit with a 0-degree angle under the action of the retaining wall structure.

[0031] When the side of the fluid receiving device needs to be erected, the stop bar 2 rotates to the vertical position and squeezes the vertical bar 21 inward again, reducing the gap 23 between the stop bars. At this time, the gap 23 between the stop bars is smaller than the limiting gap 131 of the limiting block 13, and can smoothly pass through the blocking of the limiting gap 131 and the limiting block 13 to form a clearance. The stop bar 2 is continuously squeezed and folded upward until the stop bar 2 falls into the positioning notch 142. At this time, the squeezing of the stop bar 2 is released, and the vertical bar 21 is pushed outward under the release of elastic potential energy. The side of the vertical bar 21 abuts against the positioning notch 142. The front side of the vertical bar 21 is blocked and limited by the limiting block 13, and the rear side is blocked and limited by the support block 141, forming a stable vertical position. This prevents the stop bar 2 from folding downward due to external force, so that the side and bottom of the receiving device form a 90-degree angle stable enclosure under the action of the retaining wall structure.

[0032] Furthermore, through the curved bending structure 132 of the limiting block 13 (upper smooth section 1321, middle curved bending section 1322, lower smooth section 1323), the stop lever 2 can also be locked in the limiting gap 131 at the upper smooth section 1321. At this time, the vertical rod 21 of the stop lever 2 is continuously squeezed to generate the accumulation of elastic potential energy. When the squeezing of the stop lever 2 is released, since the limiting gap 131 is smaller than the maximum width of the stop lever gap 23, the stop lever 2 cannot complete the full deformation, and part of the elastic potential energy cannot be released. This elastic potential energy will be converted into pressure, which will statically press the vertical rod 21 against the upper smooth section 1321. Since the upper smooth section 1321 is a smooth structure, it will form a large static friction force with the vertical rod 21 under the action of large pressure. At this time, the vertical rod 21 can remain stationary, realizing the limiting and locking of the stop lever 2. Thus, the stop lever 2 can achieve a hovering locking at multiple angles during rotation. When it is necessary to cancel the hovering, simply apply a downward or upward force to lever 2, thereby enabling the device to achieve hovering at multiple angles and quick unlocking.

[0033] In addition, the vertical rod 21 of the stop lever 2 can be locked in the positioning notch 142 to further enhance the structural stability; the deformable material properties of the guide section 16 can be adapted to the position adjustment requirements under different working conditions.

[0034] Because there is a guide gap 161 between the guide sections 16 on both sides of the base 1 and the base 1, and only one end of the guide section 16 is fixedly connected to the base 1, when the base 1 is inserted into the bag-shaped part of the receiving device, the bag-shaped part forms a limiting compression on the end of the base 1. The compression force forms a lever-like compression force with the connection point between the guide section 16 and the base 1 as the fulcrum. The guide section 16 undergoes slight deformation, the guide gap 161 is compressed, and the pressure applied to the guide section 16 is converted into the accumulation of elastic potential energy in the guide section 16. The protrusion 162 at the end of the guide section 16 forms friction with the flexible bag-shaped part. This friction has a large static friction force under the action of the elastic potential energy of the guide section, preventing the base 1 from coming out of the bag-shaped part at the bottom of the receiving device, and further consolidating the stability of the retaining wall structure supporting the receiving device.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and novel concept of this utility model, should be included within the protection scope of this utility model.
