Description

Technical Field

[0001] This utility model relates to the field of interception technology, and in particular to a river interception device. Background Technology

[0002] In water conservancy engineering construction, it is necessary to use appropriate interception devices to intercept the water flowing through rivers and canals, thereby facilitating the construction work. Traditional rigid interception dams (such as concrete gates) require customized production, cannot flexibly adapt to different river widths and flow velocities, and have long installation cycles.

[0003] To address the aforementioned issues, a search revealed a Chinese patent application, CN202420467840.8, which discloses a river interception device. This device includes a baffle plate with sliding baffles slidably inserted into both sides of its interior. A transmission frame is vertically fixed to the middle surface of the baffle plate's side. The overall water-blocking area between the baffle plate and the sliding baffles allows the baffle plate and sliding baffles to be adapted to river walls of varying widths, providing comprehensive interception applicability. However, this patent has the following drawbacks: although it adapts to river widths through multiple interception plates, the device height is fixed. This makes it unsuitable for rivers with significant differences in riverbed depth or those requiring dynamic adjustment of the interception height due to seasonal water level changes (such as dry and flood seasons), thus exhibiting insufficient flexibility. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A river interception device includes a frame assembly and a sandwich partition structure detachably installed inside the frame assembly. The sandwich partition structure includes two outer composite plates and an airbag sandwiched between the two outer composite plates, as well as an external air pump. A pressure gauge is fixedly connected to the outer wall of the airbag.

[0007] The outer composite plate is formed by bolting multiple pontoons together, and mounting plates are fixedly connected to the outer walls of the pontoons.

[0011] The top outer wall of both U-shaped base plates is provided with grooves.

[0012] As a further embodiment of this utility model: a slot is provided on one side of each of the two uprights, and a second sliding groove with an open top is provided on the inner wall of one side of the slot. The inner walls of the two second sliding grooves are slidably connected to the same telescopic rod.

[0032] Preferably, the top outer wall of the crossbeam 1 is provided with a plurality of positioning holes 701 at equal intervals. The inner wall of one of the positioning holes 701 is connected to a fastener 7 by a thread, and the positioning holes 701 are also provided on the top surface of the two uprights 2. The moving position of the two uprights 2 in the slide groove 101 is adjusted so that the distance between the two uprights 2 is adapted to the width of the river channel to be intercepted. Then, the fasteners 7 are screwed into the two positioning holes 701 on the crossbeam 1 and the uprights 2 from top to bottom, thereby fixing the position of the uprights 2 and making adjustment convenient.

[0033] Preferably, the bottom ends of both uprights 2 are welded with positioning cones A201; the uprights 2 are buried / inserted into the side / bottom of the river channel, and the positioning cones A201 that go deep into the ground are used to improve the stability of the equipment installation and improve the scour resistance.

[0034] Furthermore, the retractable bottom structure includes two U-shaped base plates 4 distributed in relative positions, three sliding grooves 404 formed on both sides of the U-shaped base plates 4, and an intermediate plate 403 slidably connected to the inner walls of the two sliding grooves 404 by a slider. One side of the U-shaped base plate 4 is fixed to the outer wall of one side of the upright 2 by bolts. The two U-shaped base plates 4 move synchronously with the displacement of the corresponding upright 2. The sliding grooves 404 and the intermediate plate 403 form a sliding fit, thereby ensuring that the bottom of the two uprights 2 is always connected, which can provide bottom support for the sandwich partition structure.

[0035] Preferably, the bottom outer wall of the intermediate plate 403 is fixed with multiple positioning cones B401 by bolts; the positioning cones B401 that extend deep into the ground can help improve the stability of the equipment installation and enhance its resistance to erosion.

[0036] Preferably, the structural surfaces of the frame components are coated with commercially available anti-corrosion and anti-rust coatings to adapt to long-term operation in humid environments and ensure the service life of the equipment.

[0037] Furthermore, each of the two uprights 2 has a corresponding slot 202 on one side for limiting the left and right sides of the sandwich partition structure. The inner wall of one side of the slot 202 has a sliding groove 203 with an open top. The inner walls of the two sliding grooves 203 are slidably connected to the same telescopic rod 8. The telescopic rod 8 is pulled out from the sliding groove 203, and then the sandwich partition structure made according to the width and depth of the river channel is inserted into the two opposing slots 202 and fixed. Then the telescopic rod 8 is returned to the two sliding grooves 203. Thus, the upper telescopic rod 8, the lower retractable bottom structure, and the slots 202 on both sides are used to realize the positioning and fixing of the sandwich partition structure, which is convenient for disassembly and assembly.

[0038] Preferably, the telescopic rod 8 consists of two long plates and a connecting plate that is slidably connected to one side of the two long plates;

[0039] More preferably, the telescopic rod 8 has two connecting holes 801 on one side near both ends; the connecting holes 801 can be used to fix the telescopic rod 8 to the sandwich partition structure and limit the upward extension space of the airbag 9.

[0040] As a supplement, the two uprights 2 are vertically arranged on one side and are fixed with multiple elastic bands 6 for front and rear auxiliary limiting of the sandwich partition structure by bolts.

[0041] Furthermore, the sandwich partition structure includes two outer composite plates and an airbag 9 sandwiched between the two outer composite plates, as well as an external air pump [not shown in the figure];

[0042] Preferably, a pressure gauge is fixed to the outer wall of the airbag 9 by bolts, and the size of the airbag 9 is adapted to the length of the slide groove 101 and the height of the slot 202;

[0043] Preferably, the outer composite plate is formed by bolting several pontoons 5 together, and mounting plates 501 are welded to the outer walls of the pontoons 5. The mounting plates 501 are fastened to two adjacent pontoons 5 with bolts. The outer composite plate that matches the width and depth of the river channel can be made according to this method. It is lightweight, easy to transport, and can also effectively protect the outer side of the airbag 9 that is in contact with the water.

[0044] More preferably, the top outer walls of both U-shaped base plates 4 are provided with grooves 402 that are adapted to the thickness of the mounting pieces 501; the grooves 402 limit the row of mounting pieces 501 protruding from the bottom of the sandwich partition structure, thereby assisting in the assembly and fixing effect of the sandwich partition structure.

[0045] Working principle: During assembly, adjust the position of the two uprights 2 within the slide 101 so that the distance between the two uprights 2 matches the width of the river channel to be intercepted. Then, screw the fasteners 7 from top to bottom into the two positioning holes 701 on the crossbeam 1 and the uprights 2 to fix the position of the uprights 2. Pull out the telescopic rod 8 from the slide 203, and then fasten the two adjacent floats 5 to the mounting plate 501 with bolts. Based on this method, manufacture the outer composite plate that matches the width and depth of the river channel. Then, the two outer composite panels with airbags 9 are inserted between the two slots 202 and fixed until the row of mounting pieces 501 at the bottom of the sandwich partition structure is inserted into the corresponding grooves 402 below. Then, the telescopic rod 8 is reset into the two sliding grooves 203, and the telescopic rod 8 is connected and tightened to the mounting pieces 501 at the top of the sandwich partition structure using bolts and connecting holes 801. Then, the airbags 9 are inflated using an external air pump to seal the gap between the two outer composite panels to prevent water leakage. In this structure, the upper telescopic rod 8, the lower retractable bottom structure, the slots 202 on the left and right sides, and the elastic bands 6 on the front and back sides are used to position and fix the sandwich partition structure. At the same time, the vertical, horizontal, left and right, and front and back directions of the airbags 9 can be extended and restricted to adapt to the partition size and orientation of the outer composite panels.

[0046] During installation, the upright 2 is fixed to the side / bottom of the river channel by burying or inserting it, and the positioning cones A201 and B401, which extend deep into the ground, are used to help improve the stability of the equipment installation. During use, the sandwich partition structure is used to intercept the upstream and downstream river channels, and adjustments are convenient.

[0049] Working principle: When in use, the sandwich partition structure is used to intercept the upstream and downstream river channels. During the interception, the flow rate of water flowing from the upstream river channel into the downstream river channel is regulated by the flow control valve 3 to prevent the water body from drying up and to protect downstream aquatic life.
