[0002] Water accumulates on the road and flows back into underground garages, causing serious damage to vehicles and loss of people's property. In order to cope with the disasters caused by extreme rainstorms to underground parking lots, anti-backflow measures are usually installed at the entrances and exits of underground garages to prevent water from flowing back into the garage.

[0003] Patent publication number CN219262201U discloses a water blocking device at the entrance of an underground garage. A water trough is arranged at the entrance of the underground garage.

[0040] like Figure 5 and Figure 6 As shown, the blocking assembly includes a first connecting plate 49, the number of which is two, and the first connecting plates 49 are respectively connected to the upper part of the side of the grid frame 48 that is close to each other, the number of which is two, and the fixing rods 410 are respectively connected to the side of the first connecting plate 49 that is away from each other, a sliding plate 411 is slidably connected to the fixing rod 410, a first spring 412 is connected between the sliding plate 411 and the adjacent first connecting plate 49, the first spring 412 is wound around the adjacent fixing rod 410, and a blocking net 413 is connected between the sliding plates 411.

[0041] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, the supporting mechanism includes a second connecting plate 51, the number of the second connecting plates 51 is two, the second connecting plates 51 are respectively connected to the left and right parts of the rear side of the interception frame 3, the supporting plate 52 is rotatably connected between the second connecting plates 51, and the left and right sides of the rear part of the supporting plate 52 and the adjacent second connecting plates 51 are connected with torsion springs 53, the two torsion springs 53 are both wound around the supporting plate 52, the fixing block 54 is connected to the front side of the bottom of the supporting plate 52, and a control component is arranged on the left grid frame 48.

[0042] like Figure 7 and Fig. 9 As shown, the control assembly includes a latch 55, which is slidably connected to the upper left portion of the front side of the interception frame 3, and the latch 55 is inserted into the fixed block 54. The push block 56 is connected to the upper right portion of the left grid frame 48, and when the push block 56 rotates with the left grid frame 48, it contacts the latch 55.

[0043] The device is installed below the ground at the entrance and exit of the underground garage before use, and initially, the torsion spring 53 is in a twisted state. When a rainstorm occurs, the garage staff first starts the double-rod cylinder 2, controls the telescopic end of the double-rod cylinder 2 to drive the interception frame 3 to move upward, so that the interception frame 3 rises to block the rainstorm water outside the underground garage, and then starts the reciprocating cylinder 42, controls the telescopic end of the reciprocating cylinder 42 to drive the rack 43 to move left and right, thereby driving the second rotating shaft 45 and the grid frame 48 to rotate inside and outside through the gear 47, the first rotating shaft 44 and the belt 46. The grid frame 48 will push the garbage carried by the water to the left and right sides of the device. At the same time, when the grid frame 48 rotates 90 degrees outward, it will pull the sliding plate 411 inward through the first connecting plate 49, so that the blocking net 413 moves forward, and the first spring 412 will deform first and then reset. Conversely, when the grid frame 48 rotates 90 degrees inward to reset, the blocking net 413 moves backward to reset, and the first spring 412 continues to deform first and then reset. The blocking net 413 can block the garbage outside the interception frame 3 when the grid frame 48 pushes the garbage to both sides.

[0044] When the left grid frame 48 rotates outward, the grid frame 48 will drive the push block 56 to rotate outward, and the push block 56 will push the latch 55 to the left to move it out of the fixed block 54. Under the action of the torsion spring 53, the support plate 52 will flip backward to contact the garage floor, thereby supporting the interception frame 3.

[0045] When the accumulated water recedes, first close the reciprocating cylinder 42, then manually flip the support plate 52 upward to its original position, insert the pin 55 into the fixing block 54 to fix it, and the torsion spring 53 continues to be in a twisted state. Control the telescopic end of the double-rod cylinder 2 to drive the interception frame 3 to descend back to its original position, and then close the double-rod cylinder 2.

[0046] To summarize, the garbage carried by rainwater is first removed through the grid frame 48, and then the garbage is blocked outside the interception frame 3 through the blocking net 413, and then the interception frame 3 is supported by the support plate 52 to increase the pressure resistance of the interception frame 3 and improve the water-blocking effect of the device.

[0047] Embodiment 2: Based on embodiment 1, Figure 1 and Fig.10As shown, it also includes a scraping mechanism for brushing off garbage hanging on the grid frame 48, and the scraping mechanism is arranged on the grid frame 48. The scraping mechanism includes a third connecting plate 61, and the number of the third connecting plates 61 is two. The third connecting plates 61 are respectively connected to the middle part of the side close to each other of the grid frame 48, and two fourth connecting plates 62 are connected to the middle and lower part of the front side of the interception frame 3. The number of elastic telescopic rods 63 is two, and the elastic telescopic rods 63 are respectively connected to the side away from each other of the third connecting plates 61, and the side away from each other of the elastic telescopic rods 63 is connected with a brush plate 64, and a pull rope 65 is connected between the fourth connecting plate 62 and the adjacent brush plate 64, and a fixing ring 66 is connected to the lower part of the side close to each other of the grid frame 48, and the pull rope 65 passes through the adjacent fixing ring 66.

[0048] When the grid frame 48 rotates outward, it will pull the brush plate 64 inward through the fixing ring 66 and the pull rope 65, the brush plate 64 will move inward, and the elastic telescopic rod 63 will shrink inward. When the grid frame 48 rotates outward, the brush plate 64 will move outward under the elastic action of the elastic telescopic rod 63 itself. As the grid frame 48 rotates inward and outward, the brush plate 64 will move back and forth inward and outward, thereby brushing off the garbage hanging on the grid frame 48, avoiding the grid frame 48 from being punctured by too much garbage, thereby affecting the efficiency of garbage removal.

[0049] like Figure 1 , Fig.11 and Fig.12 As shown, it also includes a reinforcement mechanism for filling the space between the support plate 52 and the interception frame 3 after the support plate 52 is flipped over. The reinforcement mechanism is arranged on the rear side of the interception frame 3. The reinforcement mechanism includes a material box 71. The material box 71 is connected to the rear side of the interception frame 3. A discharge port is opened on the bottom wall of the material box 71. A sliding frame 72 is slidably connected between the rear wall of the material box 71 and the rear wall of the interception frame 3. A second spring 73 is connected between the front of the sliding frame 72 and the interception frame 3. The second spring 73 is wound on the sliding frame 72. A sealing plate 74 for controlling the opening and closing of the discharge port is connected to the rear of the sliding frame 72.

[0050] Initially, the material box 71 is filled with foam glue. As the accumulated water gradually rises and squeezes the sliding frame 72, the accumulated water will push the sliding frame 72 backward, thereby driving the sealing plate 74 to move backward to open the discharge port of the material box 71. The second spring 73 is deformed, and the foam glue in the material box 71 will flow out. When it comes into contact with the air, the volume of the foam glue will expand rapidly, thereby filling the space between the interception frame 3 and the support plate 52. After it solidifies, it has waterproof and sealing effects and a certain strength. It can not only further block water outside the garage, but also increase the force-bearing area of ​​the support plate 52, thereby strengthening its supporting force and improving the water-blocking effect of the device. When the accumulated water recedes, under the elastic action of the second spring 73, the sliding frame 72 will drive the sealing plate 74 to move forward and reset.

[0051] like Figure 1 , Fig.13 and Fig.14 As shown, it also includes a knocking mechanism for knocking the sealing plate 74 to speed up the discharge speed. The knocking mechanism is arranged at the bottom of the material box 71. The knocking mechanism includes a connecting frame 81, the connecting frame 81 is connected to the bottom of the material box 71, the top rod 82 is slidably connected to the connecting frame 81, the third spring 83 is connected between the lower part of the top rod 82 and the connecting frame 81, the third spring 83 is wound around the top rod 82, and a toggle assembly is arranged at the lower part of the rear wall of the interception frame 3.

[0052] like Fig.14 As shown, the toggle assembly includes a wedge rod 84, which is slidably connected to the lower part of the rear wall of the interception frame 3, and the fourth spring 85 is connected between the front part of the wedge rod 84 and the interception frame 3. The fourth spring 85 is wound around the wedge rod 84, and the front, back, left and right sides of the upper part of the rear first rotating shaft 44 are all connected with toggle plates 86, and the toggle plate 86 is squeezed and fitted with the wedge rod 84, and the wedge rod 84 is squeezed and fitted with the top rod 82.

[0053] When the first rotating shaft 44 rotates, it will drive the toggle plate 86 to rotate together. The toggle plate 86 will push the wedge rod 84 backward to make it contact with the top rod 82, thereby pushing the top rod 82 upward, and the fourth spring 85 and the third spring 83 are deformed. When the toggle plate 86 rotates with the first rotating shaft 44 to separate from the wedge rod 84, under the elastic action of the fourth spring 85 and the third spring 83, the wedge rod 84 moves forward and resets, and the top rod 82 moves downward and resets. As the toggle plate 86 intermittently contacts and separates from the wedge rod 84, the top rod 82 moves up and down reciprocatingly, and the top rod 82 will knock on the sealing plate 74, thereby causing the material box 71 to vibrate, thereby accelerating the discharge speed of the foam glue therein, thereby quickly filling the space between the interception frame 3 and the support plate 52, thereby improving the water-blocking effect of the device.

[0054] like Figure 1 , Fig.15 and Fig.16 As shown, it also includes a sealing mechanism for blocking the gap between the interception frame 3 and the walls on both sides of the garage. The sealing mechanism is arranged in the interception frame 3, and the sealing mechanism includes a fifth connecting plate 91. The number of the fifth connecting plates 91 is four, and the fifth connecting plates 91 are respectively connected to the left and right sides of the upper and lower inner walls of the interception frame 3. The number of sealing blocks 92 is two, one sealing block 92 is slidably connected between the two fifth connecting plates 91 on the left, and the other sealing block 92 is slidably connected between the two fifth connecting plates 91 on the right. The upper and lower parts of the sealing block 92 and the adjacent fifth connecting plates 91 are connected with fifth springs 93, and the fifth springs 93 are wound around the adjacent sealing blocks 92. The sealing blocks 92 are made of rubber material.

[0055] Initially, the fifth spring 93 is in a compressed state. When the interception frame 3 rises upward, if there is a gap between the interception frame 3 and the walls on both sides of the garage, under the elastic action of the fifth spring 93, the sealing block 92 will move outward to block the gap to prevent accumulated water from flowing into the garage from the gap. When the interception frame 3 drops, the sealing block 92 will move inward to reset, and the fifth spring 93 returns to a compressed state. In summary, the gap between the interception frame 3 and the garage wall is blocked by the sealing block 92 to prevent accumulated water from entering the garage from the gap, thereby improving the water-blocking effect of the device.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
