Description

Technical Field

[0001] The present invention belongs to the technical field of flood prevention and water blocking, and particularly relates to an electric water blocking structure. Background Art

[0002] In recent years, rainstorm and flood disasters have occurred frequently. Once they occur, current underground engineering parts such as sunken squares and underground garage connections are all weak points in flood prevention. In the flood season or extreme weather, it is extremely easy for rainstorms to pour into the underground layer from these flood prevention weak points, causing serious property losses and personal injuries.

[0003] When a rainstorm and flood disaster strikes, it is necessary to set up a water blocking device to block the rainstorm and flood. Chinese Patent with the application number: 202111292135.6 discloses a non-powered flip-type flood prevention baffle device. This technical solution uses a leaf spring and an arc-shaped pressing plate as the rotating shaft for the flip movement of the baffle, providing torque for the flip movement of the baffle, so that the baffle can flip according to a predetermined arc without deviation. At the same time, the leaf spring mechanism plays a role in sealing and blocking water below the device. Cooperating with the locking mechanism, it realizes automatic upward flipping to block water under the condition of flooding without power, and automatically returns to its position and locks after the water recedes, without affecting passage. The structure is simple and the flood prevention ability is strong. However, although this technical solution does not require a power device and has a simple structure, there are also situations where its internal sealing disappears and it cannot operate or malfunctions. Especially in the case of long-term frequent rolling, its safety and reliability may be weakened to a certain extent. And when the rainstorm and flood recede, there will be garbage brought by the rainstorm and flood in the groove on the ground for accommodating the baffle. When the baffle returns to its position, the existing garbage affects the reset of the baffle.

[0004] Therefore, it is very necessary to invent an electric water blocking structure to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides an electric water retaining structure, such as Figures 1 to 7As shown in the figure, it includes a bottom plate 1. Symmetrically and fixedly installed on the top of the bottom plate 1 are side plates 2. The bottom plate 1 is arranged on the ground. A groove is formed in the top of the bottom plate 1. A water baffle 4 is arranged in the groove. Rotating shafts 3 are fixedly installed on both sides of the water baffle 4. The other ends of the rotating shafts 3 are rotatably connected to the inner wall of the groove. A pulling assembly is arranged on the top of the bottom plate 1 for pulling the water baffle 4 to rotate into an upright state. A receiving opening communicating with the groove is formed in the bottom of the bottom plate 1. The cross-sectional width of the receiving opening is smaller than that of the groove. Both sides of the receiving opening communicate with the outside. One side of the side plate 2 away from the receiving opening is connected to an external wall. Support plates 5 are symmetrically and rotatably installed inside the receiving opening. A cylinder 6 is fixedly installed on the side of the support plate 5 close to the side plate 2. An extrusion assembly is arranged outside the rotating shaft 3 for extruding the cylinder 6 to drive the support plate 5 to rotate. When in use, when heavy rain causes floods and the water level is too high and there is a risk of flooding, at this time, the pulling assembly drives the water baffle 4 to rotate into a vertical state, which can cooperate with the side plate 2 and the wall to block heavy rain floods. The garbage brought by the retreat of heavy rain floods remains on the surface of the support plate 5. The pulling assembly can be driven to drive the water baffle 4 to rotate downward. As the water baffle 4 rotates downward, the extrusion assembly cooperates to extrude the cylinder 6 to drive the support plate 5 to rotate upward, so that a pair of support plates 5 rotate simultaneously, making the support plate 5 in an inclined state. Then, the pulling assembly is paused. At this time, the support plate 5 is in an inclined state, so as to pour the garbage in the direction close to the side plate 2, so that the garbage is poured out of the receiving opening to the outside of the side plate 2, realizing the cleaning of the garbage on the support plate 5. Then, continue to cooperate with the pulling assembly to drive the water baffle 4 to rotate downward, and the extrusion assembly cancels the extrusion of the cylinder 6. At this time, under the action of gravity, the support plate 5 rotates back to its original position and is in a horizontal state. Finally, the water baffle 4 rotates back to its original position and is located on the support plate 5. At this time, the vehicle can pass through the bottom plate 1 and the water baffle 4, and the support plate 5 can support the water baffle 4. Thus, the blocking of the risk of flooding and the cleaning of the garbage remaining on the support plate 5 after the retreat of heavy rain floods are realized, ensuring that the water baffle 4 can be reset smoothly, and an electric push rod is used to drive the movement of the water baffle 4, with strong safety and reliability.

[0029] As Figures 2 to 3As shown, the extrusion assembly includes a connecting column 7, an inner wall of the receiving port is provided with a movable groove on one side near the cylinder 6, one end of the rotating shaft 3 extends into the movable groove, the connecting column 7 is fixedly connected to the bottom end of the rotating shaft 3, and a recess is provided on the bottom of the connecting column 7 near the cylinder 6. A vertical plate 8 is symmetrically fixedly installed at the lower part of the connecting column 7, and a movable shaft is rotatably installed between the two vertical plates 8. A toggle plate 9 is fixedly installed on the outer sleeve of the movable shaft, and a baffle 22 is fixedly installed on the top of the toggle plate 9, and the baffle 22 is located in the recess. One end of the movable shaft extends to the outer sleeve of the vertical plate 8 and a first torsion spring 10 is provided. The two ends of the first torsion spring 10 are respectively fixedly connected to the vertical plate 8 and the movable shaft. When the water retaining plate 4 rotates upward to a vertical state, it will drive the rotating shaft 3, the connecting column 7, the vertical plate 8, the movable shaft, and the toggle plate 9 to rotate accordingly. When the toggle plate 9 is in conflict with the cylinder 6, as the toggle plate 9 continues to rotate, it will bend and drive the movable shaft to rotate, so that the first torsion spring 10 is twisted and deformed to generate a force, so that the toggle plate 9 is offset from the cylinder 6. When the toggle plate 9 leaves the cylinder 6, the deformed first torsion spring 10 releases the force to drive the movable shaft and the toggle plate 9 to rotate and reset. When the water baffle plate 4 rotates downward, the toggle plate 9 rotates accordingly. When the toggle plate 9 is in conflict with the cylinder 6, due to the cooperation between the baffle 22 and the inner wall of the recess, the baffle 22 cannot rotate, and then the toggle plate 9 cannot rotate. As the toggle plate 9 rotates downward, the toggle cylinder 6 drives the support plate 5 to rotate upward. When the toggle plate 9 is rotated to separate from the cylinder 6, under the action of gravity, the support plate 5 rotates and resets to a horizontal state, and finally the toggle plate 9 is reset.

[0030] like Figure 3 As shown, the side of the recess away from the cylinder 6 is closed, and the baffle 22 can contact the inner wall of the closed side of the recess, so that after the toggle plate 9 rotates downward and contacts the cylinder 6, the toggle plate 9 cannot be deflected through the contact between the baffle 22 and the inner wall of the recess.

[0031] like Figure 3 As shown, the toggle plate 9 can contact with the cylinder 6 when rotating, and can be separated from the cylinder 6 before rotating downward back to the movable groove, so that the toggle plate 9 can be separated from the cylinder 6 after rotating downward and driving the cylinder 6 to rotate a certain distance.

[0032] like Figures 5 to 6As shown, rotating grooves are equidistantly provided on the top of the support plate 5, and a roller 11 is rotatably installed in the rotating grooves. Cavities 12 are provided on both sides of the support plate 5, and both ends of the roller 11 extend into the cavities 12 on both sides. A sprocket is fixedly installed at one end of the roller 11, and multiple sprockets are connected by a chain belt 13. One end of the roller 11 away from the cylinder 6 is sleeved with a second torsion spring 14, and the two ends of the second torsion spring 14 are respectively fixedly connected to the inner wall of the cavity 12 and one end of the roller 11. The roller 11 away from the cylinder 6 is provided with a rotating component for driving it to rotate. The support plate 5 rotates upward to cooperate with the rotating component to drive the connected roller 11 to rotate, so that the sprocket and chain belt 13 drive the remaining rollers 11 to rotate. At the same time, the second torsion spring 14 undergoes torsional deformation to generate a force. Through the rotation of the roller 11, the garbage accumulated above it can be transported toward the direction close to the side plate 2 and fall out through the receiving port, thereby avoiding the situation that the garbage cannot be separated from the support plate 5, so that the garbage cleaning is more thorough.

[0033] like Figures 5 to 6 As shown, the rotating assembly includes a fixed rod 15, which is fixedly buried in the ground. A rope 16 is fixedly connected to the top of the fixed rod 15. The end of the rope 16 away from the fixed rod 15 extends into the cavity 12 and is fixedly connected to one end of the drum 11 away from the cylinder 6. The rope 16 is wound at one end of the drum 11, and the support plate 5 rotates upward. At this time, the connected drum 11 is pulled by the rope 16 to rotate the drum 11, so that the rope 16 is released. When the support plate 5 rotates downward to reset, the second torsion spring 14 releases its force to drive the drum 11 to rotate and wind up the rope 16.

[0034] like Figure 1 As shown, the pulling assembly includes a lifting ear 17 symmetrically fixedly installed on the top of the water retaining plate 4, a cross bar 18 is horizontally inserted inside the lifting ear 17, both ends of the cross bar 18 extend to the outside of the lifting ear 17, a stopper is fixedly installed on one end of the cross bar 18, and a nut is threadedly connected to the other end, an electric push rod 20 is rotatably installed on the outside of the cross bar 18, a protective cover 19 is fixedly installed on the inner side of the side plate 2, a horizontal shaft is rotatably installed on the upper part of the inner part of the protective cover 19, and the other end of the electric push rod 20 is rotatably sleeved on the horizontal shaft, and a liquid level sensor 21 cooperating with the electric push rod 20 is provided on the outer side of the side plate 2. The liquid level sensor 21 is Static pressure liquid level sensor, when the water level reaches the liquid level sensor 21, the liquid level sensor 21 controls the electric push rod 20 to start shortening it, driving the cross bar 18, the lifting ear 17, and the water baffle 4 to rotate upward, so that the water baffle 4 is finally in a vertical state. At this time, the water baffle 4 is in contact with the protective cover 19, and a sealing strip is provided around the outer side of the water baffle 4 to improve the water-tightness. The electric push rod 20 can be started to extend it, and vice versa, the water baffle 4 can be rotated downward to reset. The liquid level sensor 21 is a liquid level sensor in the prior art, and the principle of controlling the electric push rod 20 is the prior art, which will not be elaborated here.

[0035] As Figure 1 shown, the electric push rod 20 is specifically set as a worm and worm wheel type electric push rod, and the model of the electric push rod 20 is set as DTW-2500, so that the electric push rod 20 can lock the current state and maintain the length in the case of power failure. When the power is off, the rotating nut can be separated from the cross bar 18, and the electric push rod 20 can be rotated away from the water baffle 4. The water baffle 4 can be manually lifted to a vertical state to ensure that the water baffle 4 can be used in the case of power failure. Usually, when the water baffle 4 is at the ground plane, the electric push rods 20 on both sides are in the extended state, applying a downward pressure on the water baffle 4. And because of the self-locking of the worm and worm wheel in the electric push rod 20, in the case of vehicle passage, it is more stable, avoiding the hidden danger of being lifted by the vehicle. Even in the case of power failure, self-locking can be achieved, and it can still resist the upward movement force of the water baffle 4.

[0036] Working principle: When in use, when heavy rain and floods strike and there is a risk of flooding, when the water level is too high and reaches the position of the liquid level sensor 21, the liquid level sensor 21 controls the electric push rod 20 to start and shorten it, driving the cross bar 18, the lifting ear 17, and the water baffle 4 to rotate upward, so that the water baffle 4 is finally in a vertical state. When the water baffle 4 rotates upward and is in a vertical state, it will drive the rotating shaft 3, the connecting column 7, the vertical plate 8, the movable shaft, and the toggle plate 9 to rotate accordingly. When the toggle plate 9 conflicts with the cylinder 6, as the toggle plate 9 continues to rotate, it will bend and drive the movable shaft to rotate, causing the first torsion spring 10 to torsion deformation and generate a force, when the toggle plate 9 is offset from the cylinder 6, when the toggle plate 9 leaves the cylinder 6, the deformed first torsion spring 10 releases the force to drive the movable shaft and the toggle plate 9 to rotate and reset. Finally, the water baffle 4 is fitted with the protective cover 19, and can cooperate with the side plate 2 and the wall to block the rainstorm and flood. The garbage brought by the rainstorm and flood will remain on the surface of the support plate 5. The electric push rod 20 can be started to extend it, and vice versa, the water baffle 4 can be rotated downward and reset. When the water baffle 4 rotates downward, the toggle plate 9 rotates accordingly. When the toggle plate 9 conflicts with the cylinder 6, the baffle 22 cannot rotate due to the cooperation with the inner wall of the recess, and then the toggle plate 9 cannot rotate. As the toggle plate 9 rotates downward, the toggle cylinder 6 drives the support plate 5 to rotate upward, so that a pair of support plates 5 rotate at the same time, so that the support plates 5 are The electric push rod 20 is then closed, and the support plate 5 is in an inclined state, so that the garbage is poured out in the direction close to the side plate 2, so that the garbage is poured out to the outside of the side plate 2 through the receiving port, so as to clean the garbage on the support plate 5, and then the electric push rod 20 is started again to extend it, and the water baffle plate 4 is driven to rotate downward. When the toggle plate 9 is rotated to separate from the cylinder 6, under the action of gravity, the support plate 5 is rotated and reset to a horizontal state, and finally the toggle plate 9 is reset, and finally the water baffle plate 4 is rotated and reset to be located on the support plate 5. At this time, the vehicle can pass through the bottom plate 1 and the water baffle plate 4, and the support plate 5 can be supported by being located on the water baffle plate 4, thereby achieving the blocking of flooding risks and the retreat of rainstorms and floods. When the support plate 5 is rotated downward to be reset, the second torsion spring 14 releases its force to drive the roller 11 to rotate and reel in the rope 16.
