Description

Technical Field

[0001] The invention relates to the technical field of flood prevention equipment, and in particular to a flood prevention baffle based on an underground garage. Background Art

[0002] With the acceleration of urbanization, underground garages are widely used in modern buildings. However, the risk of flood disasters they face is becoming increasingly prominent. Under extreme weather conditions such as heavy rain, urban drainage systems are often overwhelmed, causing ground water to rise rapidly. Due to its low terrain, underground garages are prone to become areas where water accumulates. Once flooded, it will not only cause serious damage to the vehicles parked in them, but may also endanger the electrical equipment, infrastructure and personnel safety in the garage, causing huge economic losses and safety hazards to car owners and property management.

[0003] Traditional flood control measures for underground garages mainly rely on sandbag stacking and floodgates. Sandbag stacking requires a large number of sandbags to be stored in advance, and a lot of manpower and material resources are spent on arranging them before the water accumulates. In addition, its flood control effect is limited and it is difficult to cope with the situation of rapid water level rise. The installation and maintenance costs of floodgates are high, and there are certain requirements for site conditions and drainage systems. It is also difficult to implement in some complex terrains or old garages. In addition, most of these traditional flood control methods lack intelligent and automated response mechanisms and cannot respond to sudden flood disasters in a timely and effective manner. Summary of the invention

[0004] The present invention provides a flood prevention baffle based on an underground garage to solve the problem that the waterproofing means of a traditional underground garage does not respond in time.

[0005] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0006] A flood baffle based on an underground garage includes a water retaining mechanism, wherein the water retaining mechanism includes a water storage tank, a drainage tank and a transverse tank opened in the ground, wherein the water storage tank is U-shaped, wherein a floating seat is slidably connected in one vertical section of the water storage tank, and the other vertical section is connected to the drainage tank, wherein the transverse tank is connected to the drainage tank, and wherein a notch is opened in the ground;

[0007] The upper part of the floating seat is connected with a water baffle, and the ground layer is connected with a guide rail matched with the water baffle. The accumulated water in the ground layer enters the water storage tank through the transverse groove and the drainage groove, so that the floating seat rises synchronously with the water level of the water storage tank.

[0008] Furthermore, it also includes a drainage mechanism, which includes a horizontal pipe and a vertical pipe connected to the horizontal pipe. A rubber column is slidably connected in the vertical pipe. The upper part of the rubber column is connected to a float through a pull rope. When the water level in the water tank rises, the float pulls the rubber column upward to block the horizontal pipe.

[0009] Furthermore, the connecting part between the drainage groove and the water storage tank is higher than the connecting part with the horizontal groove. When the water level in the water storage tank is lower than the connecting part between the drainage groove and the water storage tank, the float moves downward to make the rubber column move downward to the lower part of the connecting part between the horizontal pipe and the vertical pipe.

[0010] Furthermore, it also includes a passage mechanism, which includes pads symmetrically hinged to both sides of the water retaining plate, a limiting column is arranged on one end of the pad away from the water retaining plate, and a sliding groove cooperating with the limiting column is opened in the stratum.

[0011] Furthermore, the passage mechanism also includes an L-shaped groove, which is connected to the water storage tank. A blocking rod is slidably connected in the vertical section of the L-shaped groove. When the water level in the water storage tank rises, the blocking rod floats upward to prevent the limit column from sliding in the opposite direction.

[0012] Furthermore, a wedge block and a slot are provided on the top of the blocking rod, and when the limiting column slides along the wedge block, the blocking rod is pressed to move downward, and after the limiting column moves over the wedge block, the blocking rod moves upward so that the limiting column is engaged in the slot;

[0013] After the water level in the water storage tank drops, the blocking rod moves downward, so that the limiting column is away from the blocking rod.

[0014] Furthermore, it also includes a deceleration mechanism, which includes an N-shaped piston cylinder, the N-shaped piston cylinder is connected to the top of the guide rail, the water retaining plate is connected to a piston rod, the top of the piston rod is connected to a piston plate, the piston plate slides in one of the vertical sections of the N-shaped piston cylinder, a rectangular plate is slidably connected in the other vertical section of the N-shaped piston cylinder, and a non-Newtonian fluid is filled between the piston plate and the rectangular plate.

[0015] Furthermore, a limiting plate is vertically slidably connected in the horizontal part of the N-shaped piston cylinder, a groove is provided on the top of the limiting plate, and when the water baffle rises to the highest stroke, the limiting plate moves up to the highest stroke synchronously.

[0016] Furthermore, a cross bar is connected between the two vertical parts of the N-shaped piston cylinder, and the cross bar abuts against the lower part of the limiting plate.

[0017] Furthermore, a connecting rod is connected to the bottom of the flow limiting plate, a floating block is connected to the bottom end of the connecting rod, and the floating block floats in the water storage tank.

[0018] The beneficial effects of the present invention are analyzed as follows:

[0019] A flood baffle based on an underground garage comprises a water retaining mechanism, wherein the water retaining mechanism comprises a water storage tank, a drainage tank and a transverse tank opened in the ground. The water storage tank is U-shaped, a floating seat is slidably connected in one vertical section of the water storage tank, the other vertical section is connected to the drainage tank, the transverse tank is connected to the drainage tank, and a notch is opened in the transverse tank on the ground. A water retaining plate is connected to the upper part of the floating seat, and a guide rail matched with the water retaining plate is connected to the ground. The accumulated water in the ground enters the water storage tank through the transverse tank and the drainage tank, so that the floating seat rises synchronously with the water level of the water storage tank.

[0020] The ground is at the entrance and exit of the garage, and the water retaining mechanism will not be activated unless there is water accumulation. When water accumulates on the ground, the water flows first into the transverse trough, which can be an ordinary sewer. When the transverse trough can drain the water, excess water will not enter the water storage tank. As the amount of water accumulated in the ground increases, when the precipitation is higher than the drainage speed of the transverse trough, the water in the transverse trough enters the water storage tank through the drainage trough. As the water level in the water storage tank rises, the floating seat is lifted up by the rising water level in the water storage tank, so that the floating seat drives the water retaining plate to slide up in the guide rail, thereby making the water retaining plate block the entrance and exit of the garage to prevent accumulated water from entering the interior of the garage. The guide rail provides sealing for the edge of the water retaining plate to ensure that water does not enter the garage from both sides of the water retaining plate.

DETAILED DESCRIPTION

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Embodiment 1, as Figure 1 , Figure 2 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, a flood baffle based on an underground garage includes a water retaining mechanism 100, which includes a water storage tank 120, a drainage tank 160 and a transverse tank 150 opened in a stratum 110. The water storage tank 120 is U-shaped, and a floating seat 130 is slidably connected in one of the vertical sections of the water storage tank 120, and the other vertical section is connected to the drainage tank 160. The transverse tank 150 is connected to the drainage tank 160, and the transverse tank 150 is opened on the stratum 110; the upper part of the floating seat 130 is connected to a water retaining plate 140, and the stratum 110 is connected to a guide rail 170 that cooperates with the water retaining plate 140. The accumulated water in the stratum 110 enters the water storage tank 120 through the transverse tank 150 and the drainage tank 160, so that the floating seat 130 rises synchronously with the water level of the water storage tank 120.

[0042] The working mechanism of the flood baffle provided in this embodiment is as follows:

[0043] The ground layer 110 is located at the entrance and exit of the garage. The water retaining mechanism 100 will not be activated when there is no water accumulation. When there is water accumulation on the ground, the water first flows into the transverse groove 150, which can be an ordinary sewer. When the transverse groove 150 can drain the water, the excess water will not flow into the water storage tank 120. As the amount of water accumulated in the ground layer 110 increases, when the precipitation is higher than the drainage speed of the transverse groove 150, the water in the transverse groove 150 flows into the water storage tank 120 through the drainage groove 160. As the water level in the water tank 120 rises, the floating seat 130 is lifted up by the rising water level in the water tank 120, so that the floating seat 130 drives the water baffle 140 to slide up in the guide rail 170, and then the water baffle 140 blocks the entrance and exit of the garage to prevent the accumulated water from entering the interior of the garage. The guide rail 170 provides a seal for the edge of the water baffle 140 to ensure that water does not enter the garage from both sides of the water baffle 140. When the water in the water tank 120 is full, the water baffle 140 rises to the highest state.

[0044] Regarding the structure of the drainage mechanism 200, specifically:

[0045] The drainage mechanism 200 includes a horizontal pipe 210 and a vertical pipe 220 connected to the horizontal pipe 210. A rubber column 230 is slidably connected in the vertical pipe 220. The upper part of the rubber column 230 is connected to a float 240 through a pull rope. When the water level in the water tank 120 rises, the float 240 pulls the rubber column 230 upward to block the horizontal pipe 210.

[0046] When the water level in the water tank 120 is not high, although the float 240 is subject to buoyancy, the floating height of the float 240 is not enough to tighten the pull rope, so that the rubber column 230 will not be pulled upward. At this time, if the water flow into the water tank 120 is small, the water flow will be discharged through the horizontal pipe 210. In other words, the water at the garage entrance and exit is discharged through the horizontal groove 150 and the horizontal pipe 210 at this time, and no accumulation will occur.

[0047] In addition, when the water flow rate is large, the discharge speed of the horizontal groove 150 cannot keep up first, and then the discharge of the horizontal pipe 210 cannot keep up, so that the water level accumulated in the water tank 120 begins to rise. The rise in water level causes the float 240 to move up, and then when the float 240 moves up to the vicinity of the drainage groove 160, the float 240 pulls the rubber column 230 up through the pull rope and blocks the connecting part of the horizontal pipe 210 and the vertical pipe 220, so that the water in the water tank 120 will not be discharged through the horizontal pipe 210, thereby ensuring that the water retaining plate 140 is in a stable upward state.

[0048] Among the optional methods of this embodiment, the more preferred ones are:

[0049] The connecting part between the drainage groove 160 and the water storage tank 120 is higher than the connecting part between the drainage groove 160 and the water storage tank 120. When the water level in the water storage tank 120 is lower than the connecting part between the drainage groove 160 and the water storage tank 120, the float 240 moves downward to make the rubber column 230 move downward to the lower part of the connecting part between the horizontal pipe 210 and the vertical pipe 220.

[0050] Since the connection part between the drainage groove 160 and the water storage tank 120 is higher than the connection part between the drainage groove 160 and the transverse groove 150, the water inside the transverse groove 150 will flow into the water storage tank 120 after the water level in the transverse groove 150 rises. When the water inside the water storage tank 120 is full, the water level in the transverse groove 150 will continue to rise. That is, when the water level in the water storage tank 120 is above the lowest point of the connection part between the drainage groove 160 and the water storage tank 120, the float 240 drives the rubber column 230 to block the transverse pipe 210, and the rubber column 230 The rubber column 230 has a certain length. As the water level in the water storage tank 120 continues to rise, the rubber column 230 always keeps the horizontal pipe 210 in a blocked state. Then, when the water level of the accumulated water drops, the water level in the horizontal groove 150 drops first. At this time, the water levels in the water storage tank 120 and the drainage groove 160 drop synchronously, causing the float 240 to move downward, so that the rubber column 230 falls under gravity and moves out of the connecting portion of the horizontal pipe 210 and the vertical pipe 220, so that the water in the water storage tank 120 can be discharged through the horizontal pipe 210.

[0051] It should be noted that the water retaining plate 140 has been fully raised before water accumulates in the stratum 110, ensuring that water does not flow back into the garage.

[0052] Embodiment 2, as Figure 1-Figure 7 As shown, on the basis of Example 1, further, a passage mechanism 300 is included, and the passage mechanism 300 includes a pad 310 symmetrically hinged on both sides of the water retaining plate 140, and a limiting column 320 is arranged on the end of the pad 310 away from the water retaining plate 140, and a sliding groove cooperating with the limiting column 320 is opened in the formation 110.

[0053] The setting of the passage mechanism 300 allows pedestrians or light vehicles such as non-motor vehicles to enter and exit the garage through the entrance and exit when necessary. When the water retaining plate 140 is at the lowest state, the pad 310 is in contact with the ground. When the water retaining plate 140 rises, the water retaining plate 140 drives one end of the pad 310 to rise, while the other end of the pad 310 slides linearly on the stratum 110. After the water retaining plate 140 is fully raised, a hollow boss similar to the shape of a speed bump is formed on the stratum 110. The highest height of this boss is equal to the height of the water retaining plate 140. The formation of this boss makes it possible for the water to fluctuate when the accumulated water on the outside fluctuates. Most of the water's vibration force can be removed by the inclined pad 310, thereby ensuring that the water retaining plate 140 is not easily impacted by the water flow and that the water retaining plate 140 is not easily deformed. When the water retaining plate 140 rises to the maximum height, the position of the pad 310 is locked, so that pedestrians or non-motor vehicles can enter and exit the garage through the pad 310.

[0054] Among the optional methods of this embodiment, the more preferred ones are:

[0055] The passage mechanism 300 also includes an L-shaped groove 330, which is connected to the water storage tank 120. A blocking rod 340 is slidably connected in the vertical section of the L-shaped groove 330. When the water level in the water storage tank 120 rises, the blocking rod 340 floats upward to prevent the limiting column 320 from sliding in the opposite direction.

[0056] The L-shaped groove 330 is connected to the water storage tank 120. When the water level in the water storage tank 120 rises to near the highest level, the baffle rod 340 rises synchronously with the water baffle plate 140 due to buoyancy. At this time, the baffle rod 340 can block the limiting column 320 at the end of the pad 310, so that the pad 310 will not swing down when under weight, thereby ensuring the water-blocking effect of the water baffle plate 140.

[0057] Among the optional methods of this embodiment, the more preferred ones are:

[0058] A wedge block 341 and a slot 342 are provided on the top of the blocking rod 340. When the limiting column 320 slides along the wedge block 341, the blocking rod 340 is pressed downward. After the limiting column 320 moves over the wedge block 341, the blocking rod 340 moves upward so that the limiting column 320 is engaged in the slot 342; after the water level in the water storage tank 120 drops, the blocking rod 340 moves downward, so that the limiting column 320 is away from the blocking rod 340.

[0059] After the stopper 340 moves upward, its top is within the sliding stroke of the limit post 320, and after the stopper 340 moves upward to the end of the stroke, it is blocked by the stratum 110 and no longer moves upward. At this time, the limit post 320 continues to slide and can contact the wedge block 341 on the stopper 340, so that the continued sliding of the limit post 320 can push the stopper 340 to overcome the buoyancy and move downward through the wedge block 341. When the limit post 320 moves to pass over the wedge block 341 and is in the slot 342, the stopper 340 is moved upward by the buoyancy, so that the limit post 320 is clamped in the slot 342, and the stopper 340 can only move up and down, while the sliding direction of the limit post 320 tends to be horizontal, and then after the pad 310 is compressed, the stopper 340 can limit the limit post 320, thereby preventing the pad 310 from swinging.

[0060] When the water level in the water storage tank 120 drops, the water level in the L-shaped groove 330 will also drop, so that the blocking rod 340 can slide down, allowing the limiting column 320 to disengage from the slot 342, and the movement of the pad 310 is no longer restricted, so that the water baffle 140 can smoothly drop and reset.

[0061] Regarding the structure of the speed reduction mechanism 400, specifically:

[0062] The reduction mechanism 400 includes an N-shaped piston cylinder 420, which is connected to the top of the guide rail 170, a piston rod 410 is connected to the water baffle 140, a piston plate 430 is connected to the top of the piston rod 410, the piston plate 430 slides in one of the vertical sections of the N-shaped piston cylinder 420, a rectangular plate 440 is slidably connected in the other vertical section of the N-shaped piston cylinder 420, and a non-Newtonian fluid is filled between the piston plate 430 and the rectangular plate 440.

[0063] Since the speed of water accumulation and drainage in the water storage tank 120 is slow, the lifting speed of the water baffle 140 is also slow. At this time, the water baffle 140 drives the piston plate 430 to move slowly upward in the N-shaped piston cylinder 420, and the non-Newtonian fluid transmits force to the rectangular plate 440, causing the rectangular plate 440 to move downward. During this process, the non-Newtonian fluid will not solidify, so that the movement of the water baffle 140 is not hindered. If the pad 310 is accidentally unlocked, the water baffle 140 is subjected to a downward force at this time. This force drives the water baffle 140 to have a tendency to move downward rapidly, so that the force applied by the piston plate 430 to the non-Newtonian fluid will increase, and then the non-Newtonian fluid solidifies at this time, hindering the rapid downward movement of the water baffle 140, thereby providing safety protection for people passing on the pad 310.

[0064] Among the optional methods of this embodiment, the more preferred ones are:

[0065] The horizontal part of the N-shaped piston cylinder 420 is vertically slidably connected with the limiting plate 450 , and a groove is provided on the top of the limiting plate 450 . When the water retaining plate 140 rises to the highest stroke, the limiting plate 450 moves up to the highest stroke synchronously.

[0066] When the limiting plate 450 rises to the highest state, the water baffle 140 is also in the highest state at the same time. At this time, the non-Newtonian fluid in the N-shaped piston cylinder 420 needs to flow through the grooves on the limiting plate 450, further increasing the flow resistance of the non-Newtonian fluid and increasing the protection effect of the water baffle 140 against accidental downward movement.

[0067] Among the optional methods of this embodiment, the more preferred ones are:

[0068] A cross bar 460 is connected between two vertical portions of the N-shaped piston cylinder 420 , and the cross bar 460 abuts against the lower portion of the flow limiting plate 450 .

[0069] The setting of the cross bar 460 limits the downward movement distance of the limiting plate 450. When the limiting plate 450 contacts the cross bar 460, the lowest point of its groove is flush with the bottom surface of the horizontal section of the N-shaped piston cylinder 420, ensuring the sealing of the N-shaped piston cylinder 420.

[0070] Among the optional methods of this embodiment, the more preferred ones are:

[0071] A connecting rod 470 is connected to the bottom of the flow limiting plate 450 . A floating block 480 is connected to the bottom end of the connecting rod 470 . The floating block 480 floats in the water storage tank 120 .

[0072] When the water level in the water storage tank 120 rises to a level close to the maximum water level, the float 480 releases the water in the water storage tank 120 and floats upward due to the buoyancy, so that the flow limiting plate 450 moves upward to the N-shaped piston cylinder 420, causing greater resistance to the flow of the medium in the N-shaped piston cylinder 420;

[0073] In addition, when a flow limiting plate 450 is set in the horizontal section of the N-shaped piston cylinder 420, the medium in the N-shaped piston cylinder 420 can be replaced according to the force that the pad 310 needs to bear. A fluid medium other than a non-Newtonian fluid can be used, but the fluidity of this medium must be poor to ensure that the downward movement speed of the water retaining plate 140 can be slowed down.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
