[0033] refer to Figures 1 to 6 The present application provides a quick-install and structurally stable water-blocking device, which is arranged at the entrances and exits of buildings such as residences, shopping malls, subways, underground garages, civil air defense projects, and municipal facilities, and is used to connect with the walls on both sides of the building entrances and exits to surround the entrances and exits. The water-blocking device includes a plurality of sleeves 10 pre-buried under the ground and distributed at intervals along a preset trajectory surrounding the building entrances and exits, a plurality of columns 20 connected one-to-one with the plurality of sleeves 10, a wall-mounted C-shaped profile 40 pre-buried in the wall of the building entrance and exit, a column-mounted C-shaped profile 30 arranged on the columns 20, a water retaining plate 50 connected between the column-mounted C-shaped profiles 30 of two adjacent columns 20 and between the column-mounted C-shaped profile 30 of the column 20 and the wall-mounted C-shaped profile 40 on the wall of the building entrance and exit, and a first flexible sealing strip 60 surrounding the lower edge of the water retaining plate 50.

[0034] The sleeve 10 is vertically pre-buried under the ground, with its lower end sealed and its upper end open. The upper end opening is usually closed with a cover plate and is opened when needed. In actual installation, it is best to make the cover plate flush with the ground. A locking rod 11 is fixedly connected inside the sleeve 10.

[0035] The column 20 has a tube connecting section 21 and a plate connecting section 22. The tube connecting section 21 is used to be inserted into the sleeve 10. A locking groove 211 is provided on the tube connecting section 21. The locking groove 211 includes a vertical groove portion 2111 for the locking rod 11 to be vertically inserted from the bottom surface of the tube connecting section 21, a rotating groove portion 2112 for the locking rod 11 to be rotated and inserted from the top plane of the vertical groove portion 2111, and a locking groove portion 2113 formed by being recessed downward from the end of the rotating groove portion 2112 and used to accommodate the locking rod 11.

[0036] A flexible sealing gasket 71 is sleeved on the column 20 at the connection position between the cylinder connection section 21 and the plate connection section 22 .

[0037] The water retaining plate 50 is arranged between the two columns 20 by inserting the two side edges into the column C-shaped profile 30 of the two adjacent columns 20 one by one. The water retaining plate 50 is arranged between the columns 20 and the wall of the building entrance and exit by inserting the two side edges into the column C-shaped profile 30 and the wall C-shaped profile 40 one by one.

[0038] The water retaining device is connected to the walls on both sides of the building entrance and exit, and a plurality of sleeves 10 are pre-buried along a preset track surrounding the building entrance and exit. A plurality of columns 20 are plugged into the plurality of sleeves 10 in a one-to-one correspondence. A water retaining plate 50 is arranged between the two columns 20 and between the column 20 and the wall, and the two side edges of the water retaining plate 50 are connected to the column 20 and the wall through a C-shaped profile. Thus, the water retaining plate 50 is strongly supported and has good stability. Combined with the first flexible sealing strip 60 for preventing surface water leakage, it can effectively block deeper water accumulation and is not easy to tip over.

[0039] When the water retaining device is used, a trajectory surrounding the entrance and exit is set according to the entrance and exit of the building, a sleeve 10 and a wall C-shaped profile 40 are pre-buried along the trajectory, and columns 20 and water retaining plates 50 are prepared. A column C-shaped profile 30 is pre-installed on each column 20, and a first flexible sealing strip 60 is pre-installed on each water retaining plate 50. When encountering urban waterlogging, it is only necessary to insert the column 20 into the sleeve 10, and then insert the water retaining plate 50 between the column C-shaped profiles 30 of two adjacent columns 20, and between the column C-shaped profile 30 of the column 20 and the wall C-shaped profile 40 of the wall of the building entrance and exit to complete the installation. When inserting the column 20 into the sleeve 10, after aligning the locking rod 11 with the bottom opening of the locking groove 211, first press down the column 20 to make the locking rod 11 vertically inserted into the top of the vertical groove 2111, then rotate the column 20 to make the locking rod 11 rotate and insert into the end of the rotating groove 2112, and finally release the column 20. Since the elastic force of the flexible sealing gasket 71 acts on the column 20 and lifts the column 20, the locking rod 11 falls into the locking groove 2113, thereby firmly locking the column 20 on the sleeve 10, and the operation is simple and convenient. Therefore, after the sleeve 10 and the wall-mounted C-shaped profile 40 are pre-buried, and the column-mounted C-shaped profile 30 and the first flexible sealing strip 60 are pre-installed, the water retaining device of the present application becomes very convenient to install on site, and can be quickly installed.

[0040] The flexible sealing gasket 71 also has the function of preventing water from leaking from the sleeve 10 .

[0041] refer to Figure 1 In the embodiment of the present application, the preset track surrounding the entrance and exit of the building is an open rectangle. At this time, the central angle between the two C-shaped profiles 30 of the column 20b at the corner is set to 90°, and the central angle between the two C-shaped profiles 30 of the columns 20a at other locations is set to 180°. It should be noted that the column 20 is provided with two C-shaped profiles 30, and the central angle between the two C-shaped profiles 30 of the columns 20 may be different on each column 20. When applied, it should be specifically set on each column 20 according to the actual preset track.

[0042] refer to Figure 2 and Figure 6 , taking the column 20a and the column 20b as examples, the connection structure between the column 20 and the sleeve 10, the column C-shaped profile 30 and the water retaining plate 50 is explained.

[0043] The locking rod 11 is a horizontally arranged crossbar passing through the axis of the sleeve 10, the vertical groove portion 2111 of the locking groove 211 is formed by opening in a diameter form from the lower end surface of the tube connecting section 21 and then extending vertically upward to a preset height, the rotating groove portion 2112 of the locking groove 211 is formed by rotating a preset angle from the top of the vertical groove portion 2111 around the axis plane of the column 20, and the locking groove portion 2113 of the locking groove 211 is formed by being recessed downward from the end of the rotating groove portion 2112. In this way, the installation of the column 20 can be completed by first pressing down the column 20 and then rotating the column 20, and the operation is simple and fast.

[0044] Preferably, the preset height is h≥40 mm, and the preset angle is 60°≤β≤120°. In this embodiment, the preset height is 50 mm, and the preset angle is 90°.

[0045] The column 20 can be a hollow cylinder or a solid cylinder. In this embodiment, the column 20 is a hollow cylinder, which reduces weight, facilitates handling, and saves material costs.

[0046] Combination Figure 3 As shown, after the column 20 is installed, the flexible sealing gasket 71 is pressed against the ground by the column C-shaped profile 30. Due to the elastic force of the flexible sealing gasket 71 acting on the column C-shaped profile 30, the column 20 moves up a short distance, so that the locking rod 11 is locked into the locking groove 2113. When the locking rod 11 is in the locking groove 2113, the up-and-down movement and rotation of the column 20 can be restricted, so that the column 20 is stably locked on the sleeve 10.

[0047] Combination Figure 4 and Figure 5 As shown, the connection structure of the column 20 and the column C-shaped profile 30, and the column C-shaped profile 30 and the water retaining plate 50 is explained by taking the column 20a as an example. The inner side of the column C-shaped profile 30 is provided with a second flexible sealing strip 72. At this time, when the first flexible sealing strip 60 is wrapped around the lower edge of the water retaining plate 50, a non-glue position for plugging the C-shaped profile should be reserved at both ends of the lower edge of the water retaining plate 50. The second flexible sealing strip 72 is used to prevent water from leaking from the joint between the water retaining plate 50 and the column C-shaped profile 30.

[0048] A third flexible sealing strip 73 is sandwiched between the column C-shaped profile 30 and the plate connecting section 22, and the third flexible sealing strip 73 is used to seal the joint between the column C-shaped profile 30 and the plate connecting section 22. The column C-shaped profile 30 is locked to the plate connecting section 22 by a threaded connector that sequentially passes through the second flexible sealing strip 72, the bottom of the groove of the column C-shaped profile 30, the third flexible sealing strip 73 and the wall of the hollow cylinder, so that the column C-shaped profile 30 can be disassembled for cleaning.

[0049] In other embodiments, the column C-shaped profile 30 may also be integrally formed with the column 20 .

[0050] like Figure 2 As shown, a top cover 80 is detachably mounted on the top of the column 20 , and the top cover 80 has a cover ear 81 for covering the upper end opening of the column C-shaped profile 30 .

[0051] like Figure 2 and Figure 5 As shown, the upper edge of the water retaining plate 50 is surrounded by a U-shaped aluminum plate 90 .

[0052] The column C-shaped profile 30 is vertically installed on the column 20. When installing the water baffle 50 between the two columns 20, it is only necessary to align the lower end of the side of the water baffle 50 with the upper end opening of the column C-shaped profile 30 and then press down the water baffle 50 to move the water baffle 50 from top to bottom until it abuts against the ground. The operation is simple and fast.

[0053] The structure of the wall-facing C-shaped profile 40 is the same as that of the column-facing C-shaped profile 30 , and a second flexible sealing strip 72 is also provided on the inner side of the wall-facing C-shaped profile 40 .

[0054] by Figure 7 The figure shows the installation process of the water retaining plate 50 when it is installed between the wall C-shaped profile 40 and the column C-shaped profile 30. When the wall C-shaped profile 40 is set vertically, if the upper end opening is outside the wall, the installation method of the water retaining plate 50 is the same as when it is installed between two columns 20, that is, it is inserted from top to bottom. When the wall C-shaped profile 40 is set vertically and the upper end opening is inside the wall, or the wall C-shaped profile 40 is tilted upward inward to the column 20, or the wall C-shaped profile 40 is tilted upward outward to the column 20, it is necessary to reserve a translation space in the wall C-shaped profile 40, first insert the corresponding side edge of the water retaining plate 50 horizontally into the middle translation space of the wall C-shaped profile 40, then install the column 20, and then move the water retaining plate 50 horizontally in the direction away from the wall surface, so that the other side edge of the water retaining plate 50 is inserted into the column C-shaped profile 30. Therefore, the installation of the water retaining plate 50 and the wall-mounted C-shaped profile 40 is also simple and quick.

[0055] In some embodiments, when the ground is rough, the water-blocking device further comprises a ground treatment structure, which is pre-buried between the two columns 20 and between the column 20 and the wall-mounted C-shaped profile 40, and is used to abut against the first flexible sealing strip 60 to strengthen the sealing strength between the first flexible sealing strip 60 and the ground to prevent ground water leakage. Figure 8The ground treatment structure includes a U-shaped channel steel 101 and a silicone structural sealant 102. The U-shaped channel steel 101 opens upward and the bottom plate is locked to the ground concrete by expansion bolts 103. The silicone structural sealant 102 is filled in the U-shaped channel steel 101 and in the gap between the outer wall of the U-shaped channel steel 101 and the inner wall of the ground slot hole.

[0056] In some embodiments, a water level sensor and a security alarm connected to the water level sensor are also included, and the water level sensor is arranged on the wall of the C-shaped profile 40 or the wall of the building entrance. Such arrangement is used to trigger an alarm when the ground water exceeds a preset value, reminding security personnel to set up a water retaining device.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments only express several implementation methods of the present application and should not be construed as limiting the scope of the patent application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be subject to the attached claims.
