Description

Technical Field

[0001] The utility model relates to the field of water conservancy projects, in particular to a retractable flood prevention and water retaining device. Background Art

[0002] Water is an indispensable and precious resource in human production and life, but its distribution and flow in its natural state often cannot meet human needs. The construction of water conservancy projects is a necessary means to control water flow, prevent flood disasters, and regulate and distribute water resources to meet the needs of human life and production. Flood control baffles, also known as water blocking boards, flood control boards, water-blocking boards, etc., are devices used to block and control the flow of rainwater. They are widely used in urban drainage systems, flood control facilities and other fields. Flood control baffles play an important role in urban flood control and drainage and emergency rescue. With the acceleration of urbanization and the frequent occurrence of extreme weather events, traditional flood control baffles seem to be powerless in the face of sudden heavy rainfall and flood disasters.

[0003] The existing flood control and water retaining devices mainly have the following problems:

[0004] 1. Individual water retaining devices exist independently and are not easy to connect: The existing water retaining plates have independent structures and lack effective connection methods. The water retaining length cannot be flexibly adjusted according to actual needs, resulting in limited flood control effects when used on wide water surfaces. In actual applications, when a wider water surface needs to be covered, it is difficult to effectively connect multiple water retaining plates, resulting in unsatisfactory overall water retaining effects.

[0005] 2. Inconvenient to fold and unfold, and takes up a lot of space: Existing water retaining plates are usually fixed structures and do not have the function of folding and unfolding. They need to be disassembled and stored after use, which is cumbersome to operate and takes up a large storage space. Summary of the invention

[0006] The purpose of the utility model is to provide a retractable flood prevention and water retaining device to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] Provided is a retractable flood control and water retaining device, comprising a mounting plate assembly, a water retaining mechanism being rotatably connected to the mounting plate assembly, and a driving assembly being rotatably connected to the mounting plate assembly; wherein

[0009] The water retaining mechanism comprises:

[0010] A water baffle assembly, wherein the upper end of the water baffle assembly is rotatably connected to a secondary connecting rod assembly, and the lower end of the water baffle assembly is rotatably connected to a tertiary connecting rod assembly.

[0011] Furthermore, the mounting plate assembly includes:

[0012] Two mounting plates, the upper end of one mounting plate is rotatably connected to a driving assembly, the upper and lower ends of the left sides of the two mounting plates are fixedly connected to hinge blocks, and the upper and lower sides of both ends of the water baffle assembly are respectively hinged to the hinge blocks on the two mounting plates.

[0013] Furthermore, a limit axis is fixedly connected to the upper end of the mounting plate, and the driving assembly includes:

[0014] A cylinder, one end of which is rotatably connected to a limiting shaft, an output end of which is rotatably connected to one end of a push rod, and the other end of which is fixedly connected to one end of a water baffle assembly.

[0015] Furthermore, the water baffle assembly comprises:

[0016] Two water baffle bodies are arranged horizontally, and both ends of the two water baffle bodies are fixedly connected with a rotating shaft. The rotating shaft fixedly connected at one end of the two water baffle bodies is hinged to the hinge block, and the upper end of a rotating shaft hinged to the hinge block is fixedly connected to the other end of the push rod, and the upper and lower sides of the other ends of the two water baffle bodies are rotatably connected through a secondary connecting rod assembly and a tertiary connecting rod assembly respectively.

[0017] Furthermore, one of the hinge blocks is fixedly connected to a rotating shaft 1, and the secondary connecting rod assembly includes:

[0018] Push rod 2, one end of which is rotatably connected to shaft 1, and the other end of which is rotatably connected to a right-angle rod, and both ends of the right-angle rod are rotatably connected to the upper ends of two adjacent shafts on two water baffle bodies.

[0019] Furthermore, the three-stage connecting rod assembly includes:

[0020] Two push rods three, one end of the two push rods three is respectively fixedly connected to the lower ends of two adjacent rotating shafts on the two water baffle bodies, and the other end of the two push rods three is respectively rotatably connected to the two ends of the push rod four.

[0021] The beneficial effects of the utility model are:

[0022] Expandable water retaining area: The utility model can achieve a larger water retaining effect through the linkage connection of multiple water retaining plate components to adapt to the needs of water surfaces of different widths. When the cylinder is extended, the output end of the cylinder pushes the push rod to move. Since the other end of the push rod is fixedly connected to the rotating shaft, the rotating shaft is fixedly connected to the water baffle body, and the other end of the cylinder is rotatably connected to the limiting shaft, when the cylinder is extended, the cylinder pushes the push rod to rotate, and at the same time, the push rod drives the rotating shaft to rotate on the hinge block, thereby driving the water baffle body to rotate, so that the water baffle body is folded, and at the same time, one end of the cylinder rotates on the limiting shaft. When the cylinder is retracted, the output end of the cylinder pushes the push rod to move. Since the other end of the push rod is fixedly connected to the rotating shaft, the rotating shaft is fixedly connected to the water baffle body, and the other end of the cylinder is rotatably connected to the limiting shaft, when the cylinder is retracted, the cylinder pushes the push rod to rotate, and at the same time, the push rod drives the rotating shaft to rotate in the opposite direction on the hinge block, thereby driving the water baffle body to rotate in the opposite direction, so that the water baffle body is unfolded, and at the same time, one end of the cylinder rotates in the opposite direction on the limiting shaft. This arrangement makes the water retaining area larger and the water retaining effect better.

[0023] Convenient folding and unfolding operation, small space occupation: The utility model adopts cylinder drive and multi-stage connecting rod mechanism to realize automatic folding and unfolding of the water baffle plate, which is easy to operate and saves manpower. Since one end of the push rod 2 is rotatably connected to the rotating shaft 1, and the other end of the push rod 2 is rotatably connected to the right-angle rod, and the two ends of the right-angle rod are respectively rotatably connected to the upper ends of the two adjacent rotating shafts on the two water baffle plate bodies, when the water baffle plate body rotates, the push rod 2 is driven to rotate on the rotating shaft 1, so that the other end of the push rod 2 pushes the right-angle rod to rotate, and then the two adjacent water baffle plate bodies are flipped, thereby realizing the folding and unfolding effect of the water baffle plate body, since one end of the two push rods 3 is respectively fixedly connected to the lower ends of the two adjacent rotating shafts on the two water baffle plate bodies, and the other ends of the two push rods 3 are respectively rotatably connected to the two ends of the push rod 4, when one push rod 3 rotates, the other end pushes the push rod 4 to rotate, and then the other push rod 3 rotates, thereby realizing the folding and unfolding effect of the water baffle plate body, making the folding and unfolding of the device more convenient and quick, and occupying less space.

[0024] Stable and reliable structural design: The utility model enhances stability through multi-point hinges. Each water baffle assembly is connected at multiple points through hinge blocks and rotating shafts to ensure that each part moves in a coordinated manner when unfolding and folding, reducing shaking and offset. At the same time, connecting rod transmission is adopted to distribute force evenly. Secondary and tertiary connecting rod assemblies are adopted to make the water baffle evenly stressed during the driving process, avoiding deformation or damage caused by excessive local force. At the same time, a limit design is adopted to prevent loosening. One end of the cylinder is fixedly connected through a limit shaft to ensure that the cylinder is in a stable position during operation and will not loosen due to long-term use, thereby improving the durability and reliability of the overall device.

[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] The utility model provides the following preferred embodiments:

[0036] The water retaining mechanism 2 comprises:

[0037] The water baffle assembly 21 has a secondary connecting rod assembly 22 rotatably connected to its upper end, and a tertiary connecting rod assembly 23 rotatably connected to its lower end.

[0038] Since the left and right ends of the water baffle assembly 21 are rotatably connected to the mounting plate assembly 1, the upper end of the water baffle assembly 21 is rotatably connected to the secondary connecting rod assembly 22, and the lower end of the water baffle assembly 21 is rotatably connected to the tertiary connecting rod assembly 23, when the driving assembly 3 is working, the water baffle assembly 21 is unfolded under the action of the secondary connecting rod assembly 22 and the tertiary connecting rod assembly 23, thereby achieving the effect of water blocking.

Rod 132 rotates, thereby driving one end of the water baffle assembly 21 to rotate on the hinge block 111, so that the water baffle is folded. When the cylinder 31 contracts, the output end of the cylinder 31 pulls the push rod 132 to move. Since the other end of the push rod 132 is fixedly connected to one end of the water baffle assembly 21, the water baffle assembly 21 is rotatably connected to the hinge block 111, and one end of the cylinder 31 rotates in the opposite direction on the limit shaft 112. At the same time, the other end of the cylinder 31 drives the push rod 132 to rotate in the opposite direction, thereby driving one end of the water baffle assembly 21 to rotate in the opposite direction on the hinge block 111, so that the water baffle is unfolded.

When the cylinder 31 is extended, the cylinder 31 pushes the push rod 32 to rotate. When the cylinder 31 contracts, the output end of the cylinder 31 pushes the push rod 32 to move. Since the other end of the push rod 32 is fixedly connected to the rotating shaft 212, the rotating shaft 212 is fixedly connected to the water baffle body 211, and the other end of the cylinder 31 is rotatably connected to the limit shaft 112, when the cylinder 31 contracts, the cylinder 31 pushes the push rod 32 to rotate, and at the same time, the push rod 32 drives the rotating shaft 212 to rotate in the opposite direction on the hinge block 111, thereby driving the water baffle body 211 to rotate in the opposite direction, so that the water baffle body 211 is expanded, and at the same time, one end of the cylinder 31 rotates in the opposite direction on the limit shaft 112.
