Description

Technical Field

[0001] The invention relates to the technical field of water conservancy projects, and in particular to a water retaining structure for an underground garage. Background Art

[0002] The underground garage water retaining device is a type of facility designed to prevent water from entering the underground garage. The core function of the underground garage water retaining device is to prevent external water sources from seeping into the garage. These devices can effectively block the water flow when the water level rises, reduce the damage to the garage caused by floods, and protect the vehicles and equipment in the garage from water damage.

[0003] In the prior art, an automatic waterproof gate or a manual waterproof gate is usually installed at the entrance of the underground garage to block the entrance of the underground garage to prevent high-level water from flowing into the underground garage. However, both of them still have the following problems: the manual waterproof gate requires staff to discover the danger in the first time and close the entrance through a water retaining plate or sandbags, which not only requires a large amount of labor but also has great safety hazards. If an automatic waterproof gate is used, the water retaining plate is rotated so that the horizontal water retaining plate located underground or in the device is rotated 90° to block the entrance. However, the rotatable water retaining plate must have gaps on both sides with the wall. At this time, high-level water will penetrate through the gaps on both sides, resulting in a lower water retaining effect, and the hinge of the water retaining plate cannot be absolutely sealed, and there is a possibility of water seepage. Summary of the invention

[0004] In view of the fact that the manual waterproofing in the prior art requires a lot of labor and poses a safety hazard, and the problem that the gaps on both sides and the hinges of the automatic waterproof water retaining plate are prone to water seepage, an underground garage water retaining structure is proposed.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1-Figure 6, which is the first embodiment of the present invention, provides an underground garage water retaining structure, including a middle plate 1, a front plate 2 fixedly installed on one side of the middle plate 1, a rear plate 3 fixedly installed on the side of the middle plate 1 away from the front plate 2, an arc plate 4 fixedly installed on one side of the front plate 2 and the rear plate 3, and also includes a water retaining unit installed on the middle plate 1, the water retaining unit includes a rotating component installed on the upper end of the middle plate 1 and a closing component arranged on both sides of the middle plate 1; the rotating component includes two mounting grooves opened on the front plate 2, two rotating shafts 5 rotatably installed on the inner walls of the two mounting grooves, two rotating sleeves 6 fixedly installed on the two rotating shafts 5, and two rotating sleeves 6 fixedly installed on the two rotating shafts 5. 6, a water baffle 7 between the middle plate 1, a plurality of slide rails 8 fixedly mounted on the middle plate 1, a sliding block 9 slidably mounted on the plurality of slide rails 8, a plurality of mounting seats 10 fixedly mounted at the lower end of the water baffle 7, a deflection rod 11 hingedly mounted between the mounting seat 10 and the corresponding sliding block 9, a filling plate 12 fixedly mounted on the upper end of the water baffle 7, and a supporting block 13 fixedly mounted at the lower end of the water baffle 7; the end face shape of the rotating sleeve 6 is L-shaped, the upper end of the filling plate 12 is arc-shaped, the height of the mounting seat 10 is equal to the distance between the lower end of the water baffle 7 and the upper end of the middle plate 1, a complete assembly is installed inside the water baffle 7, and a driving assembly is installed between the plurality of sliding blocks 9.

[0035] Reference Figure 4 as well as Figure 10-11 The complete assembly includes a sliding groove 14 provided at the lower end of the water retaining plate 7, a limiting groove 15 provided at both sides of the upper end of the sliding groove 14, a limiting plate 16 slidably installed inside the two limiting grooves 15, a closing plate 17 fixedly installed between the two limiting plates 16, and a gravity plate 18 fixedly installed at the lower end of the closing plate 17 for increasing the sealing performance. The closing plate 17 and the gravity plate 18 are slidably arranged inside the sliding groove 14, and the gravity plate 18 is made of lead material; the driving assembly includes a synchronous plate 19 fixedly installed between a plurality of sliding blocks 9, a push plate 20 fixedly installed at the middle end of the synchronous plate 19, a square groove provided on the rear plate 3, a cylinder 21 fixedly installed in the square groove, and a push rod 22 fixedly installed on the telescopic end of the cylinder 21. The push rod 22 is sealed and slidable and passes through the rear plate 3, and one end is fixedly connected to the push plate 20. A liquid level sensor (not shown in the figure) is provided on the front plate 2, and a controller (not shown in the figure) is provided in the square groove. The controller is electrically connected to the liquid level sensor and the cylinder 21.

[0036] Specifically, the water baffle 7 is used to block water flow, and the filling plate 12 is used to make the upper end of the water baffle 7 be at the same height level as the front plate 2 and the rear plate 3, so that the car can drive normally when entering the underground garage. At the same time, the purpose of being set to an arc shape is that when the water baffle 7 is used to block water, the arc surface of the filling plate 12 can effectively reduce the impact force of the water flow on the water baffle 7, and improve the stability of the water baffle 7 when blocking water. The support block 13 is used to support the water baffle 7 to prevent the water baffle 7 from being deformed due to the weight of the car and affecting its water blocking quality. The push plate 20 and the synchronous plate 19 are driven in the horizontal direction by the telescopic end of the cylinder 21, so that the deflection rod 11 drives the water baffle 7 to deflect. When the water baffle 7 is deflected by 90°, it is used to block the water flow from entering the underground garage. The function of the complete assembly is: because there is a hinge at the water baffle 7 In the gap, in order to prevent water from penetrating through the gap, an L-shaped rotating sleeve 6 and a complete assembly are set, so that when the water baffle 7 is deflected 90°, the closing plate 17 slides downward under the action of the gravity plate 18 to close the lower end of the water baffle 7, effectively preventing water from penetrating through the hinge of the water baffle 7 and affecting the water retaining quality. At the same time, the gravity plate 18 has a large mass, which can enable the gravity plate 18 to be in close contact with the upper end of the middle plate 1, so that the sealing of the lower end is better. The synchronous plate 19 is used to drive multiple sliding blocks 9 to slide synchronously in the horizontal direction to achieve a linkage effect. While the deflection rod 11 drives the water baffle 7 to deflect, it can support the water baffle 7 to prevent the water flow from having a large impact force on the water baffle 7, causing the water baffle 7 to tilt, thereby improving the stability of the water baffle 7 when blocking water flow. The function of the liquid level sensor is: when the water level at the garage entrance reaches the set threshold, the liquid level sensor transmits a signal to the controller, and the controller is used to control the opening and closing of the cylinder 21. After the controller receives the signal from the liquid level sensor, the controller controls the opening of the cylinder 21. The opening of the cylinder 21 causes the water baffle 7 to deflect and block the water flow.

[0037] During use, when the water level at the entrance of the underground garage rises and reaches the set threshold, the liquid level sensor transmits a signal to the controller. After receiving the signal, the controller controls the opening of the cylinder 21. After the cylinder 21 is opened, the push plate 20 is driven to move in the direction of the horizontal front plate 2 through the telescopic end. The push plate 20 drives multiple sliding blocks 9 to move synchronously through the synchronous plate 19. During the movement of the sliding block 9, due to the force of the deflection rod 11, the water baffle plate 7 is driven to deflect with the rotating shaft 5 as the axis. After the water baffle plate 7 is deflected by 90°, the water baffle plate 7 is used to block the water flow. At the same time, when the water baffle plate 7 is deflected, the closing plate 17 slides along the sliding groove 14 under the gravity of the gravity plate 18. When the water baffle plate 7 is deflected, the gravity plate 18 is tightly fitted with the upper part of the middle plate 1, and the lower end of the water baffle plate 7 (the hinge of the water baffle plate 7) is closed. Through the cooperation of the water baffle plate 7, the closing plate 17 and the gravity plate 18, the water flow is effectively blocked.

[0038] Example 2, reference Figure 5-Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the inflation component includes two inflation cylinders 32 fixedly installed on both sides of the upper wall of the middle plate 1, a piston plate 33 slidably installed inside the two inflation cylinders 32, a semicircular groove provided at the upper end of the middle plate 1, a reset plate 34 slidably installed in the semicircular groove, a connecting rod 35 fixedly installed between the piston plate 33 and the reset plate 34, a matching rod 36 fixedly installed on the side wall of the reset plate 34 away from the connecting rod 35, a connecting pipe 37 fixedly installed between the inflation cylinder 32 and the inflation rubber 24, a reset element is installed between the reset plate 34 and the inflation cylinder 32, and the reset element includes two outer plates 38 fixedly installed on the outer wall of the inflation cylinder 32, and a spring rod 39 fixedly installed between the two outer plates 38 and the reset plate 34.

[0039] Specifically, the function of the inflatable component is as follows: when the sliding block 9 is sliding, it drives the piston plate 33 to slide on the inner wall of the inflatable cylinder 32. During the sliding process, the air in the inflatable cylinder 32 is squeezed into the inflatable rubber 24. The inflatable rubber 24 is located on both sides of the deflected water baffle 7. When the internal pressure of the inflatable rubber 24 increases, it will expand. During the expansion process, the inflatable rubber 24 will automatically fill the gaps on both sides of the water baffle 7, the closing plate 17 and the gravity plate 18 to improve the sealing performance of the water baffle 7 and prevent water from penetrating through both sides of the water baffle 7, affecting its water-retaining effect and quality. The travel of the sliding block 9 when sliding on the slide rail 8 is divided into two ends. The first section is used to drive the deflection of the water retaining plate 7. When the sliding block 9 slides to the second stroke, the sliding block 9 contacts the matching rod 36, and drives the piston plate 33 to slide in the inflation cylinder 32 by squeezing the matching rod 36, and inflates the inflatable rubber 24. The function of the reset element is: when the water level drops, the cylinder 21 drives the sliding block 9 to slide in the opposite direction through the telescopic end, and the spring rod 39 in the compressed state generates an elastic force on the reset plate 34. The reset plate 34 slides in the opposite direction under the action of the elastic force, and drives the piston plate 33 to slide in the opposite direction through the connecting rod 35. At the same time, the gas inside the inflatable rubber 24 is drawn back into the inflation cylinder 32, so that the inflatable rubber 24 is restored.

[0040] During use, when the sliding block 9 moves in the first stroke of the slide rail 8, the water baffle 7 is driven to deflect. When the sliding block 9 moves in the second stroke, the sliding block 9 contacts the matching rod 36. At this time, the sliding block 9 generates a horizontal thrust on the matching rod 36 to drive the matching rod 36 to slide in the horizontal thrust direction. During the sliding process of the matching rod 36, the piston plate 33 is driven to slide inside the inflatable cylinder 32 through the connecting rod 35. During the sliding process, the piston plate 33 presses the air inside the inflatable cylinder 32 into the inflatable rubber 24, and the inflatable rubber 24 expands as the air enters. During the expansion process, the gaps on both sides of the water baffle 7 are filled to improve the sealing performance of both sides of the water baffle 7 and prevent water from penetrating from both sides of the water baffle 7. At the same time, when the water level drops, the telescopic end of the cylinder 21 telescopes in the opposite direction, driving the sliding block 9 to slide in the opposite direction in the horizontal direction, thereby driving the water baffle 7 to reset. At the same time, the spring rod 39 generates a reverse thrust on the reset plate 34, driving the reset plate 34 to slide in the opposite direction, and resetting the piston plate 33. When the piston plate 33 is reset, the air inside the inflatable rubber 24 is pumped back into the inflatable cylinder 32, so that the inflatable rubber 24 is restored.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3, reference Figure 8-Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the protection component includes a driving tooth plate 25 fixedly installed on both sides of the synchronization plate 19, a transmission shaft 26 fixedly installed on both sides of the upper end of the middle plate 1, a mounting plate 27 fixedly installed on the side walls of the two side plates 23, two horizontal grooves provided on the two mounting plates 27, a sliding tooth plate 28 slidably installed in the two horizontal grooves, a transmission gear 29 rotatably installed on the transmission shaft 26, a placement groove provided on the two side plates 23, a pull rod 30 fixedly installed at one end of the two sliding tooth plates 28, a protection plate 31 slidably installed in the placement groove, and one end of the pull rod 30 is fixedly connected to the middle end of the side wall of the protection plate 31, and the two ends of the transmission gear 29 are respectively meshed with the corresponding driving tooth plate 25 and the sliding tooth plate 28, and the two pull rods 30 both slide in the corresponding placement grooves. The end face size of the protection plate 31 is larger than the end face size of the strip groove.

[0043] Specifically, the protective component is used to protect the inflatable rubber 24 to prevent the inflatable rubber 24 from being scratched and cracked by the outside world under normal conditions. When the water baffle 7 is in a horizontal state, the protective plate 31 seals the inflatable rubber 24 in the strip groove. When the water baffle 7 deflects to block water, the sliding block 9 drives the sliding tooth plate 28 to slide in the horizontal direction through the driving tooth plate 25 and the transmission gear 29 during the first stroke movement, and drives the protective plate 31 to slide in the placement groove through the pull rod 30, thereby releasing the protection of the inflatable rubber 24. When the sliding block 9 slides to the second stroke, the inflatable rubber 24 is inflated. At the same time, when the water baffle 7 is reset and the inflatable rubber 24 is restored, the protective plate 31 is reset to protect the inflatable rubber 24 again.

[0044] During use, when the telescopic end of the cylinder 21 is extended and retracted to drive the synchronous plate 19 to slide in the horizontal direction, the driving tooth plate 25 on the synchronous plate 19 moves synchronously. During the movement, the driving tooth plate 25 drives the transmission gear 29 to rotate and then drives the sliding tooth plate 28 to move in the opposite direction. During the reverse movement of the sliding tooth plate 28, the protective plate 31 is driven to move synchronously through the pull rod 30, so that the protective plate 31 moves into the placement groove, and the inflatable rubber 24 is connected to the outside world for subsequent inflation. When the water level drops, when the water baffle 7 deflects and resets in the opposite direction, the inflatable rubber 24 recovers after the second stroke movement. At this time, after the sliding block 9 moves to the first stroke, the driving tooth plate 25 on the synchronous plate 19 meshes with the transmission gear 29 again, driving the transmission gear 29 to rotate in the opposite direction, thereby driving the sliding tooth plate 28 to reset. At the same time, the pull rod 30 drives the protective plate 31 to reset, so that the protective plate 31 slides into the strip groove to continue to protect the inflatable rubber 24.

[0045] The remaining structure is the same as that of Example 2.

[0046] Based on the embodiments 1-3, the working principle of the present invention is as follows: when the water level at the entrance of the underground garage rises and reaches the set threshold, the liquid level sensor transmits a signal to the controller. After receiving the signal, the controller controls the opening of the cylinder 21. After the cylinder 21 is opened, the push plate 20 is driven to move in the direction of the horizontal front plate 2 through the telescopic end. The push plate 20 drives multiple sliding blocks 9 to move synchronously through the synchronous plate 19. During the movement of the sliding block 9, due to the force of the deflection rod 11, the water baffle plate 7 is driven to deflect around the rotating shaft 5 as the axis. After the water baffle plate 7 is deflected by 90°, the water baffle plate 7 is used to block the water flow. At the same time, when the water baffle plate 7 is deflected, the closing plate 17 slides along the sliding groove 14 under the gravity of the gravity plate 18. When the water baffle plate 7 is deflected, the gravity plate 18 is tightly fitted with the upper part of the middle plate 1 to close the lower end of the water baffle plate 7 (the hinge of the water baffle plate 7). Through the cooperation of the water baffle plate 7, the closing plate 17 and the gravity plate 18, the water flow is effectively blocked.

[0047] When the sliding block 9 moves in the first stroke of the slide rail 8, the driving tooth plate 25 on the synchronous plate 19 moves synchronously. During the movement, the driving tooth plate 25 drives the transmission gear 29 to rotate and then drives the sliding tooth plate 28 to move in the opposite direction. During the reverse movement of the sliding tooth plate 28, the protective plate 31 is driven to move synchronously through the pull rod 30, so that the protective plate 31 moves into the placement groove, and the inflatable rubber 24 is connected to the outside world to facilitate subsequent inflation, and at the same time drives the water baffle 7 to deflect. When the sliding block 9 moves in the second stroke, the sliding block 9 and the matching rod 36 When the mating rod 36 contacts each other, the sliding block 9 generates a horizontal thrust on the mating rod 36, driving the mating rod 36 to slide in the horizontal thrust direction. During the sliding process of the mating rod 36, the piston plate 33 is driven to slide inside the inflation cylinder 32 through the connecting rod 35. During the sliding process, the piston plate 33 presses the air inside the inflation cylinder 32 into the inflatable rubber 24. The inflatable rubber 24 expands with the entry of air. During the expansion process, the gaps on both sides of the water retaining plate 7 are filled, thereby improving the sealing performance on both sides of the water retaining plate 7 and preventing water from penetrating from both sides of the water retaining plate 7.

[0048] After the water level drops, the telescopic end of the cylinder 21 telescopes in the opposite direction, driving the sliding block 9 to slide in the opposite direction in the horizontal direction, thereby driving the water baffle 7 to reset. At the same time, the spring rod 39 generates a reverse thrust on the reset plate 34, driving the reset plate 34 to slide in the opposite direction, and resetting the piston plate 33. While resetting the piston plate 33, the air inside the inflatable rubber 24 is drawn back into the inflatable cylinder 32, so that the inflatable rubber 24 is restored. After the inflatable rubber 24 is restored after the second stroke movement ends, at this time, after the sliding block 9 moves to the first stroke, the driving tooth plate 25 on the synchronous plate 19 is meshed with the transmission gear 29 again, driving the transmission gear 29 to rotate in the opposite direction, thereby driving the sliding tooth plate 28 to reset. At the same time, the protection plate 31 is reset through the pull rod 30, so that the protection plate 31 slides into the strip groove to continue to protect the inflatable rubber 24.

[0049] 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 preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
