[0002] Floods seriously threaten the safety of people's lives and property. After a flood occurs, urban basements face the problem of rainwater backflow during the flood season. Currently, the above-mentioned areas generally use flood control baffles to prevent rainwater backflow during rainfall.

[0003] The retractable basement driveway entrance flood barrier disclosed in patent application number 202121376083.6 includes a flood barrier body, a first steel plate is fixed to the rear surface of the flood barrier body, a second steel plate is rotated on the bottom end of the first steel plate, and a third steel plate is installed at one end of the first steel plate and the second steel plate. It is characterized in that both the first steel plate and the second steel plate are provided with positioning components for positioning and installing the third steel plate; the top surface of the flood barrier body is symmetrically provided with fixing components for storing and fixing the third steel plate and the second steel plate.

[0004] In the above-mentioned comparative patent, floods are blocked by the flood baffle body. However, in actual conditions, there is a certain gap between the flood baffle body and the ground, and the sealing performance is poor. Floods may still slowly pass through the gap, so a solution is urgently needed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application provides a flood-proof baffle at the entrance of a building basement.

[0006] The present application provides a flood-proof barrier for the entrance of a building basement using the following technical solution:

[0007] A flood baffle at the entrance of a building basement, comprising two side supports and guide grooves provided on opposite sides of the two side supports, a main baffle being slidably inserted between the two guide grooves, a sealing strip being fixedly connected to the bottom of the main baffle, the length of the sealing strip being the same as that of the main baffle, movable insertion rods being movably inserted on both sides of the main baffle, an opening being provided in the side wall of the side support communicating with the guide groove, a positioning block being fixedly connected to the side wall of the side support, a bolt being threadedly inserted on the positioning block, and when the insertion rod is pressed, one end of the insertion rod is passed through the opening, and the lower end of the bolt is in contact with the insertion rod.

[0008] By adopting the above technical solution, the bolts are rotated to tighten the plug rod, and the main baffle is further tightened, so that the contact between the sealing strip and the ground is closer, thereby filling the gap, avoiding floods as much as possible, and improving the flood prevention effect.

[0009] Preferably, a cavity is formed inside the main baffle. Sockets are formed on both sides of the cavity. Lead screws are rotatably inserted into the inner walls on both sides of the cavity, and guide rods are fixedly connected thereto. Nut blocks are sleeved on the lead screws in a threaded manner. The guide rods movably penetrate through the nut blocks. The end of the nut block is fixedly connected to the insertion rod. The insertion rod is located inside the cavity, and one end of the insertion rod passes through the socket.

[0010] By adopting the above technical solution, the lead screw is driven to rotate, so that the nut block moves along the horizontal straight line direction, so that the end of the insertion rod passes through the socket and the opening, and then the bolt is rotated. The lower end of the bolt abuts against the insertion rod to press the insertion rod.

[0011] Preferably, the other end of the lead screw is fixedly connected with a driven bevel gear. A power assembly for driving the two driven bevel gears to rotate synchronously is arranged inside the cavity.

[0012] By adopting the above technical solution, the power assembly drives the two driven bevel gears to rotate, and the driven bevel gears drive the corresponding lead screws to rotate; in this way, the synchronous movement of the insertion rods on both sides can be realized simultaneously.

The bevel gear transmission structure is relatively simple, the installation and adjustment are relatively easy, and the bevel gear transmission usually has a high transmission efficiency.

[0015] Preferably, two handles are fixedly connected to the top of the main baffle, and the handles are integrally in an inverted U shape.

[0016] By adopting the above technical solution, by lifting the main baffle by hand, it is convenient to lift the whole main baffle. The position and shape of the handle enable the operator to easily grasp and apply sufficient force.

[0017] Preferably, the insertion rod is in a long strip structure, and the socket is in a rectangular structure.

[0018] By adopting the above technical solution, the insertion rod is in a long strip shape, so that when contacting with the bolt, the plane of the insertion rod contacts with the bolt, which increases the contact area and improves the fixing effect; the structure of the socket is adapted to the insertion rod, and the cross-sectional area of the socket is slightly larger than the cross-sectional area of the insertion rod to ensure that the insertion rod can pass through the socket smoothly.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] After the main baffle is inserted between the two side supports, the rotary rod is rotated to drive the active bevel gear to rotate, and the active bevel gear drives the two driven bevel gears to rotate, and the driven bevel gear drives the corresponding screw rod to rotate, so that the nut block moves along the horizontal straight line direction, so that the end of the insertion rod passes through the socket and the opening. At this time, the insertion rod is located below the bolt; by rotating the bolt, the lower end of the bolt contacts the insertion rod, tightening the insertion rod, and further tightening the main baffle, so that the contact between the sealing strip and the ground is closer, thereby filling the gap, avoiding floods as much as possible, and improving flood control effects.

[0030] The following is combined with Figures 1-7 This application is described in further detail.

[0031] An embodiment of the present application discloses a flood control baffle for the entrance of a building basement, which includes two side supports 1 and guide grooves 101 opened on the opposite sides of the two side supports 1. According to the size requirements of the basement entrance, the two side supports 1 are fixed at the basement entrance through fasteners. A main baffle 2 is slidably inserted between the two guide grooves 101. A sealing strip 3 is fixedly connected to the bottom of the main baffle 2. Rubber is a common sealing material. The sealing strip 3 made of rubber has good oil resistance, wear resistance and aging resistance, and is suitable for the sealing requirements in various environments. The length of the sealing strip 3 is the same as the length of the main baffle 2. The sealing strip 3 should have sufficient compression performance and elasticity, and can still maintain good contact with the ground after compression. The sealing strip 3 can adapt to the surface characteristics and shape of the ground, and at the same time maintain sufficient hardness to ensure close contact with the ground, and can maintain its function after compression; Movable insertion rods 10 are inserted on both sides of the main baffle 2. An opening 102 communicated with the guide groove 101 is opened on the side wall of the side support 1. A positioning block 4 is fixedly connected to the side wall of the side support 1. A bolt 5 is threadedly inserted into the positioning block 4. When the insertion rod 10 is pressed, one end of the insertion rod 10 passes through the opening 102, and the lower end of the bolt 5 abuts against the insertion rod 10.

[0032] Drive the insertion rod 10 to directly below the bolt 5, and then rotate the bolt 5 to press the insertion rod 10, further pressing the main baffle 2, so that the contact between the sealing strip 3 and the ground is closer, thereby filling the gap, as much as possible avoiding floods from passing through and improving the flood control effect.

[0033] A detachable structural design is adopted between the side support 1 and the main baffle 2. Pull the main baffle 2 upward and directly remove the main baffle 2 from the guide groove 101 on the side support 1; The detachable structure enables the connection between the side support 1 and the main baffle 2 to be quickly disassembled when the main baffle 2 needs to be replaced, without the need for overall replacement or complex disassembly steps; The detachable structure allows different sizes of the main baffle 2 to be replaced according to actual needs. The detachable structure enables the disassembled side support 1 and main baffle 2 to be reinstalled and used without being damaged or invalidated due to disassembly, thereby improving the reuse rate of components and the overall cost-effectiveness.

[0034] Refer to Figure 4 , a cavity 201 is opened inside the main baffle 2. Sockets 202 are opened on both sides of the cavity 201. Lead screws 6 are rotatably inserted into the inner walls of both sides of the cavity 201, and guide rods 8 are fixedly connected to both sides. A nut block 9 is threadedly sleeved on the lead screw 6. The guide rod 8 movably penetrates through the nut block 9. The end of the nut block 9 is fixedly connected to the insertion rod 10. The insertion rod 10 is located inside the cavity 201, and one end of the insertion rod 10 passes through the socket 202.

[0035] Drive the lead screw 6 to rotate, causing the nut block 9 to move along the horizontal straight line direction, so that the end of the insertion rod 10 passes through the socket 202 and the opening 102, and then rotate the bolt 5. The lower end of the bolt 5 abuts against the insertion rod 10 to press the insertion rod 10. Moreover, the transmission mode between the lead screw 6 and the nut block 9 has a self-locking function, enabling the insertion rod 10 to be stably held in the current position without self-sliding.

[0036] Refer to Figure 6 , a driven bevel gear 7 is fixedly connected to the other end of the lead screw 6, and a power assembly for driving the two driven bevel gears 7 to rotate synchronously is arranged inside the cavity 201.

[0037] Drive the two driven bevel gears 7 to rotate through the power assembly, and the driven bevel gears 7 drive the corresponding lead screws 6 to rotate, so that the synchronous linear motion of the insertion rods 10 on both sides can be realized simultaneously.

[0038] Refer to Figure 1 and 6 , the power assembly includes a driving bevel gear 11 and a rotating rod 12 fixed to the end of the driving bevel gear 11. The driving bevel gear 11 meshes with the two driven bevel gears 7. The rotating rod 12 is rotatably inserted into the main baffle 2, and the other end of the rotating rod 12 penetrates to the outside of the main baffle 2.

[0039] Rotate the rotating rod 12 to drive the driving bevel gear 11 to rotate, and the driving bevel gear 11 drives the two driven bevel gears 7 to rotate, so as to simultaneously realize the mutual separation of the insertion rods 10 on both sides, making the end of the insertion rod 10 move below the bolt 5, facilitating the subsequent pressing work; the above bevel gear transmission structure is relatively simple, the installation and adjustment are relatively easy, and the bevel gear transmission usually has a high transmission efficiency.

[0040] Refer to Figure 1 , two handles 13 are fixedly connected to the top of the main baffle 2, and the handles 13 are integrally in an inverted U shape.

[0041] By lifting the main baffle 2 by hand through the handle 13, it is convenient to lift the main baffle 2 as a whole. The position and shape of the handle 13 enable the operator to easily grasp and apply sufficient force.

[0042] Refer to Figure 7 , the insertion rod 10 is in a long strip structure, and the socket 202 is in a rectangular structure.

[0043] The insertion rod 10 is in a long strip shape, so as to ensure that when contacting the bolt 5, the plane of the insertion rod 10 contacts the bolt 5, which increases the contact area and improves the fixing effect; the structure of the socket 202 is adapted to the insertion rod 10, and the cross-sectional area of the socket 202 is slightly larger than the cross-sectional area of the insertion rod 10, ensuring that the insertion rod 10 can smoothly pass through the socket 202.

[0044] The implementation principle of a flood barrier at the entrance of a building basement in an embodiment of the present application is as follows:

[0045] First, according to the size requirements of the basement entrance, the two side supports 1 are fixed at the basement entrance. After the main baffle 2 is inserted between the two side supports 1, the rotary rod 12 is rotated to drive the active bevel gear 11 to rotate, and the active bevel gear 11 drives the two driven bevel gears 7 to rotate, and the driven bevel gear 7 drives the corresponding screw rod 6 to rotate. The guide rod 8 has a guiding effect on the nut block 9, so that the nut block 9 moves along the horizontal straight line direction, so that the end of the insertion rod 10 passes through the socket 202 and the opening 102. At this time, the insertion rod 10 is located below the bolt 5; by rotating the bolt 5, the lower end of the bolt 5 is in contact with the insertion rod 10, and the insertion rod 10 is tightened, which finally realizes the tightening of the main baffle 2, making the contact between the sealing strip 3 and the ground more fit and tight, thereby filling the gap between the two, avoiding flood water from flowing through the gap as much as possible, and further improving the flood control effect.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
