Description

Technical Field

[0001] The present invention relates to the field of flood prevention devices, and in particular to an intelligent flood prevention and water retaining mechanism and a flood prevention system for an underground garage. Background Art

[0002] When urban floods occur, underground garages are often the worst-hit areas. To prevent rainwater from entering the garage when floods occur, property staff usually pile sandbags or set up baffles at the entrance of the garage to block the accumulated water and prevent the accumulated water from entering the garage. However, the water retaining structure set up by the above means has low strength and can only play a protective role when the rainfall is small. In the case of heavy rainfall, the baffles or sandbags are prone to collapse and cannot play a good protective role. At the same time, the above method of water blocking is time-consuming and labor-intensive.

[0003] In order to solve the above problems, Chinese patent application number 2022110207830 discloses a waterproof water retaining structure for an underground garage, which includes a ground cavity, wherein the ground cavity is opened at the entrance of an underground reservoir, and a baffle assembly is installed in the ground cavity, wherein the baffle assembly is used to block rainwater, and a water retaining assembly is installed on the baffle assembly; a deceleration assembly is also installed in the ground cavity, wherein the deceleration assembly is used to remind vehicles entering the underground garage to decelerate; two transmission assemblies are symmetrically arranged between the baffle assembly and the deceleration assembly, and the two transmission assemblies are used to control the baffle assembly The transmission assembly is equipped with a sealing assembly; when the transmission assembly drives the baffle assembly to block water from entering the underground garage entrance, the water-blocking assembly starts to work, the controller controls the extension of the electric telescopic rod, and the extension of the electric telescopic rod drives the counterweight plate to move, thereby driving several water-blocking airbags to unfold, and at the same time controls its water pump to pour rainwater into the water-blocking airbags, and fills several water-blocking airbags with rainwater through the connecting pipe, and several water-blocking airbags play a role of blocking water together. At the same time, when the rainwater fills the water-blocking airbags, the water-blocking airbags wrap the upper end of the baffle groove to prevent vehicles or pedestrians from colliding with the upper end of the baffle groove, thereby improving the safety of the device. The above-mentioned water-blocking structure notifies the lifting of the baffle assembly, and while using the baffle to block water, the water-blocking assembly on the baffle assembly can also use the water pump to pour rainwater into the water-blocking airbag of the water-blocking assembly, and the water-blocking airbag and the water-blocking plate jointly achieve water blocking. The above-mentioned water retaining plate and water retaining airbag are lifted and supported by transmission components, and the structural stability is poor. The lifting height is limited, and the lifting height cannot be adjusted according to the rainfall. At the same time, the lifting height is also limited by the connecting rod mechanism to drive the water retaining plate to lift. When the rainfall is heavy, it cannot play a good protective role. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an intelligent flood prevention and water retaining mechanism and flood prevention system for an underground garage, so as to solve the problems in the prior art that the water retaining plate in the garage water retaining structure has limited lifting height, cannot adjust the lifting height independently according to the rainfall, and has poor structural stability.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: An intelligent flood prevention and water retaining mechanism for an underground garage comprises an underground groove arranged along the width direction of a garage entrance road, two guide columns arranged symmetrically on both sides of the underground groove are installed, the lower ends of the two guide columns are pre-buried in the underground groove, the upper ends extend out of the underground groove and are close to the top position of the garage, and the side ends of the two guide columns are fixedly connected to the corresponding garage side walls and underground groove side walls; a slide groove arranged along the height direction is provided on each of the two guide columns, and a baffle plate is provided between the two guide columns, which is slidably matched with the guide columns on the same side on the left and right sides, the baffle plate is placed in the underground groove, the upper end is in the same plane as the notch of the underground groove, and can be extended out of the underground groove after being driven by a lifting mechanism, and form a water retaining wall together with the ground and the two guide columns, and return to the initial position under the drive of the lifting mechanism; the lifting mechanism is provided with two, including a stepping motor, a transmission screw and at least one slider, the output end of the stepping motor is connected to the transmission screw through a coupling, the slider is sleeved on the transmission screw, is threadedly connected to the transmission screw, and the side end is fixedly connected to the side end of the baffle plate; the baffle plate is placed in the underground groove. In this way, part of the guide column is embedded and fixed underground, and the other part is extended out of the ground, set near the top of the garage, and fixed between the wall, so as to provide sufficient space for the installation and sliding of the baffle. At the same time, after the baffle is lifted, it can form a water retaining wall across the garage passage with the side wall, thereby achieving the effect of water retaining. In this way, there is no gap between the baffle and the side wall, and there will be no water leakage, and the water retaining effect is good. After the top surface of the baffle and the notch of the underground groove are in the same plane, the top surface of the baffle can be used as part of the road surface in the application, which will not affect the use of the road surface on sunny days. The lifting mechanism is placed on the guide column, and there is no need to dig underground separately, so that the deep groove area excavated is small, which will not affect the strength and use of the garage floor, and is suitable for the transformation of most garage water retaining mechanisms. At the same time, the lifting mechanism adopts a structure of screw and slider, which can effectively form a support for the baffle, the structure is stable, and the lifting mechanism is set on both sides, and the baffle is lifted and lowered smoothly.

[0006] Furthermore, the baffle can also be placed at the upper end of the two guide columns, and the depth of the underground groove is set between 5-25mm; the baffle can move up and down under the drive of the lifting mechanism, and the lower end is inserted into the underground groove, sealed and connected with the side wall of the underground groove, and together with the ground and the two guide columns, forms a water retaining wall; the baffle rises to a set height under the drive of the lifting mechanism, and then returns to the initial position. In this way, in addition to setting the initial position of the baffle underground, in specific applications, the baffle can also be suspended above the ground. When water blocking is needed, the baffle is lowered to the ground and embedded in the underground groove to achieve water blocking.

[0007] Furthermore, a flexible rubber sheet is provided at the top of the baffle, and the flexible rubber sheet is in an inverted V shape or a trapezoidal shape, and the width is greater than the thickness of the baffle. In this way, when the initial position of the baffle is underground, the flexible rubber sheet provided at the top can not only prevent the upper end of the baffle from being squeezed and deformed when a vehicle passes by, play a protective buffering effect on the baffle, but also prevent external impurities from entering the underground trough.

[0008] Furthermore, the baffle is made of polyethylene, and a plurality of reinforcing ribs are arranged on the back side. In this way, the baffle has high strength and can withstand high water pressure, and at the same time, it is light in weight and does not require too much power from the lifting mechanism.

[0009] Furthermore, a radar sensor, a battery and a controller are installed on or beside one of the guide columns. The battery is electrically connected to the radar sensor, the controller and the stepper motor. The radar sensor is used to detect the water level and transmit the detected water level information to the controller. The controller controls the start and stop of the stepper motor according to the received water level information, thereby controlling the lifting height of the baffle. In this way, after the radar sensor is set on the guide column, the precipitation on rainy days can be monitored by the radar sensor. The controller determines whether to start the lifting mechanism and the lifting height control of the lifting mechanism according to the received information. For the situation that the initial position of the baffle is underground, when the rainfall is large, the height of the baffle is controlled to rise higher, and when the rainfall is medium, the height of the rise is smaller. For the situation that the initial position of the baffle is above the ground and is suspended, when the rainfall reaches a preset value, the baffle is directly controlled to descend and extend into the underground trough to cooperate with the underground trough.

[0010] Furthermore, the battery is charged by connecting to the mains, or connected to a solar panel to be powered by the solar panel. In this way, the battery can power various devices, and the solar panel can power the battery when the mains fails or is disconnected, and then the battery can power other devices, so as to avoid the stepper motor and other electrical equipment from not being able to be used normally in an emergency.

[0011] Further, a transparent cover is provided on the storage battery and the controller. In this way, the transparent cover provided can protect the storage battery and the controller, and prevent rainwater from entering and affecting their service life.

[0012] An underground garage flood prevention system includes at least two intelligent flood control and water retaining mechanisms arranged at intervals along the length direction of the garage entrance road. The intelligent flood control and water retaining mechanisms are as described above. In front of the intelligent flood control and water retaining mechanism at the front end, a ditch is also provided along the width direction of the underground garage road, and a grille plate is provided on the ditch. When the two baffles in the two intelligent flood control and water retaining mechanisms are simultaneously raised or lowered to form a retaining wall, a reservoir is formed between the two retaining walls and the side wall of the garage. A water storage ditch is provided between two adjacent intelligent flood control and water retaining mechanisms, and a water pump is provided in the water storage ditch. The water outlet of the water pump is connected to a water guide pipe and guided to a municipal pipe network or a water storage device. In this way, after multiple flood control and water retaining mechanisms are provided, multiple baffles are opened underground. In application, if the rainfall is extremely heavy, the baffles can be raised or lowered one after another according to the situation, so as to form multi-level protection. The water reservoir formed by the water retaining board, the ground and the side wall of the garage can recycle rainwater or export it to the municipal pipeline network. The recycled rainwater can be used for garden watering or directly introduced into the municipal network. With the dual functions of water retaining and pumping, the protection formed is better.

[0016] Example 1 like Figure 1-Figure 4As shown, the intelligent flood prevention and water retaining mechanism for the underground garage provided in this embodiment includes an underground trough 2 arranged along the width direction of the garage entrance road, and two guide columns 1 arranged symmetrically on both sides of the underground trough 2 are installed. The lower ends of the two guide columns 1 are pre-buried in the underground trough 2, and the upper ends extend out of the underground trough 2 and are close to the top of the garage, and the side ends of the two guide columns 1 are fixedly connected to the corresponding garage side walls and the side walls of the underground trough 2; each of the two guide columns 1 is provided with a slide groove 11 arranged along its height direction, and a baffle 4 is provided between the two guide columns 1 on the left and right sides, which is slidably matched with the guide columns 1 on the same side, and the baffle 4 is placed in the underground trough 2, and the upper end is connected to the ground The notches of the lower groove 2 are in the same plane, and can extend out of the underground groove 2 after being driven by a lifting mechanism 3, and form a water retaining wall together with the ground and two guide columns 1, and return to the initial position under the drive of the lifting mechanism 3; the lifting mechanism 3 is provided with two, including a stepping motor 33, a transmission screw 35 and at least one slider 42, the output end of the stepping motor 33 is connected to the transmission screw 35 through a coupling 34, the slider 42 is sleeved on the transmission screw 35 (the length of the transmission screw 35 is set according to specific needs, which is only for illustration in the figure), and is threadedly connected with the transmission screw 35, and the side end is fixedly connected to the side end of the baffle 4; the baffle 4 is placed in the underground groove 2. In this way, a part of the guide column 1 is pre-buried and fixed in the ground, and the other part extends out of the ground, is set near the top of the garage, and is fixed between the wall, thereby providing sufficient space for the installation and sliding of the baffle 4. At the same time, after the baffle 4 is lifted, it can form a water retaining wall across the garage passage with it and the side wall, thereby achieving the effect of water retaining. In this way, there is no gap between the baffle 4 and the side wall, and there will be no water leakage, and the water retaining effect is good. After the top surface of the baffle 4 is in the same plane as the notch of the underground groove 2, the top surface of the baffle 4 can be used as a part of the road surface in the application, and will not affect the use of the road surface on sunny days. The lifting mechanism 3 is placed on the guide column 1, and there is no need to dig underground separately, so that the excavated deep groove area is small, which will not affect the strength and use of the garage floor, and is suitable for the transformation of most garage water retaining mechanisms. At the same time, the lifting mechanism 3 adopts a structure coordinated with a lead screw and a slider 42, which can effectively form a support for the baffle 4, and the structure is stable. The lifting mechanism 3 is set on both sides, and the baffle 4 is lifted and lowered smoothly.

[0017] Specifically, the guide column 1 can be made of concrete, or metal or plastic. The lifting mechanism 3 also includes a guide rail back plate 31, a motor bracket 32 ​​and a screw assembly seat 36. The guide rail back plate 31 is fixedly installed in the guide column 1 through screws. The motor bracket 32 ​​and the screw assembly seat 36 are respectively fixedly installed at the upper and lower ends of the guide rail back plate 31. The stepper motor 33 is fixedly installed on the motor bracket 32. The upper end of the transmission screw is connected to the coupling 34, and the lower end is connected to the screw assembly seat 36 through a bearing. A plurality of guide rods 37 are also provided between the motor bracket 32 ​​and the screw assembly seat 36. Both sides of the slider 42 are provided with sliding sleeves that are integrally formed with the slider and sleeved on the guide rods 37. The sliders 42 on the left and right sides of the baffle 4 are symmetrically arranged and fixedly connected to the baffle 4 through fasteners.

[0018] Furthermore, a flexible rubber sheet 41 is provided at the top of the baffle 4, and the flexible rubber sheet 41 is in an inverted V shape or a trapezoidal shape, and its width is greater than the thickness of the baffle 4. In this way, when the initial position of the baffle 4 is underground, the flexible rubber sheet 41 provided at the upper end can not only prevent the upper end of the baffle 4 from being squeezed and deformed when a vehicle passes by, but also play a protective and buffering role for the baffle 4, and can also prevent external impurities from entering the underground tank 2.

[0019] Furthermore, the baffle plate 4 is made of polyethylene, and a plurality of reinforcing ribs are arranged on the back. In this way, the baffle plate 4 has high strength and can withstand high water pressure, and at the same time, it is light in weight, and the power requirement for the lifting mechanism 3 is not too large.

[0020] like Figure 5 As shown, a radar sensor 7, a battery 9 and a controller 8 are also installed on one of the guide columns 1 or beside the guide column 1. The battery 9 is electrically connected to the radar sensor 7, the controller 8 and the stepper motor 33. The radar sensor 7 is used to detect the water level and transmit the detected water level information to the controller 8. The controller 8 controls the start and stop of the stepper motor 33 according to the received water level information, thereby controlling the lifting height of the baffle 4. In this way, after the radar sensor 7 is set on the guide column 1, the precipitation on rainy days can be monitored by the radar sensor 7. The controller 8 determines whether to start the lifting mechanism 3 and the lifting height control of the lifting mechanism 3 according to the received information. For the situation that the initial position of the baffle 4 is underground, when the rainfall is large, the height of the baffle 4 is controlled to rise higher, and when the rainfall is medium, the height of the rise is smaller. For the situation that the initial position of the baffle 4 is above the ground and is suspended, when the rainfall reaches a preset value, the baffle 4 is directly controlled to descend and extend into the underground trough 2 to cooperate with the underground trough 2.

[0021] Furthermore, the battery 9 is charged by connecting to the mains, or connected to a solar panel 6 and powered by the solar panel 6. Specifically, the solar panel 6 is installed on the top of a support frame. In this way, the battery 9 can power various devices, and the solar panel can power the battery 9 when the mains fails and is disconnected, and then power other devices through the battery 9, so as to avoid the stepper motor 33 and other electrical equipment from not being able to be used normally in an emergency.

[0022] Further, a transparent cover is provided on the storage battery 9 and the controller 8. The transparent cover can protect the storage battery 9 and the controller 8, and prevent rainwater from entering and affecting their service life.

[0023] Example 2 like Figure 6 As shown, the difference between the intelligent flood prevention and water retaining mechanism of the underground garage in this embodiment and that in Example 1 is that the use of the baffle 4 and the depth of the underground trough 2 are different. Specifically, the baffle 4 in this embodiment is placed on the upper end of the two guide columns 1, and the depth of the underground trough 2 is set to between 5-25mm; the baffle 4 can move downward under the drive of the lifting mechanism 3, and the lower end is inserted into the underground trough 2, and is sealed and connected with the side wall of the underground trough 2, and forms a water retaining wall together with the ground and the two guide columns 1; the baffle 4 rises under the drive of the lifting mechanism 3 and sets the height, and then returns to the initial position. In this way, in addition to setting the initial position of the baffle 4 underground, in specific applications, the baffle 4 can also be suspended above the ground, and when water is needed, the baffle 4 is lowered to the ground and embedded in the underground trough 2 to achieve water retaining. The lifting mechanism 3 used can be a winch and a pull rope, or it can be the screw lifting mechanism 3 in Example 1.

[0024] To ensure the sealing between the baffle 4 and the ground, a rubber pad 43 is provided at the lower end of the baffle 4, or a sealing ring is provided in the underground groove 2 to match the lower end of the baffle 4. Of course, in specific applications, the underground groove 2 may not be provided, and the baffle 4 may be directly pressed against the ground to form a water retaining wall.

[0025] Example 3 like Figure 7As shown, the underground garage flood prevention system provided by this embodiment includes at least two intelligent flood prevention and water retaining mechanisms arranged at intervals along the length direction of the garage entrance road. The intelligent flood prevention and water retaining mechanism is as described in Example 1 or Example 2. In front of the intelligent flood prevention and water retaining mechanism at the front end, a ditch is also provided along the width direction of the underground garage road, and a grille plate is provided on the ditch; when the two baffles 4 in the two intelligent flood prevention and water retaining mechanisms are simultaneously raised or lowered to form a retaining wall, a reservoir 5 is formed between the two retaining walls and the side wall of the garage; a water storage ditch is provided between two adjacent intelligent flood prevention and water retaining mechanisms, and a water pump is provided in the water storage ditch, and the water outlet of the water pump is connected to a water guide pipe and guided to the municipal pipe network or water storage device. In this way, after multiple flood prevention and water retaining mechanisms are set, there are multiple baffles 4 underground. In application, if the rainfall is extremely heavy, the baffles can be raised or lowered one after another according to the situation, so as to form multi-level protection. The water reservoir 5 formed by the water retaining plate, the ground and the side wall of the garage can recycle rainwater or export it to the municipal pipe network. The recycled rainwater can be used for garden watering or directly introduced into the municipal network. Under the dual effects of water retaining and pumping, better protection is formed.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution should be included in the scope of the claims of the present invention.
