[0055] The connecting plate 200 is specifically a frame structure with a net rope 120. The connecting plate 200 is detachably connected to the placement rack 100, and the connecting plate 200 blocks the opening of the placement rack 100, so that the connecting plate 200 and the placement rack 100 together limit the multiple counterweight balls 300 in the placement rack 100; under the action of the counterweight balls 300, the filtering effect of sand and gravel is achieved, and the flow rate of mud and sand is effectively reduced.

[0056] The specific installation process of the counterweight ball 300 is as follows: first place the counterweight ball 300 into the placement rack 100, and then install the connecting plate 200 on the placement rack 100. The connecting plate 200 blocks the opening of the placement rack 100 to form a closed box-type structure, and multiple counterweight balls 300 can be installed. When the counterweight ball 300 needs to be replaced, the connecting plate 200 is removed from the placement rack 100, and the counterweight ball 300 can be taken out of the placement rack 100.

[0057] Regarding the connection method between the connecting plate 200 and the placement rack 100, as shown in FIG. Figure 2 As shown, specifically:

[0058] The bridge pier anti-scour structure further includes a connection assembly 700 ; the connection plate 200 is detachably mounted on the opening of the frame body 110 via the connection assembly 700 .

[0059] Specifically, the connecting assembly 700 includes a screw 710 and a threaded sleeve 720; the screw 710 passes through the connecting plate 200 and the frame body 110, and both ends of the screw 710 pass through the connecting plate 200; the threaded sleeve 720 is threadedly connected to the end of the screw 710 passing through the connecting plate 200. When the connecting plate 200 needs to be installed on the placement rack 100, the screw 710 is passed through the connecting plate 200 and the frame body 110, and both ends of the screw 710 are passed out, and the threaded sleeve 720 is used to thread the two ends of the screw 710 respectively. The connecting plate 200 can be installed on the placement rack 100 by utilizing the cooperation of the threaded sleeve 720 and the screw 710.

[0060] In addition, the connection components 700 are arranged in four groups, and the four groups of connection components 700 are respectively located at the four corners of the connection plate 200 .

[0061] In an optional embodiment, the connecting frame 400 is rotatably connected to the connecting plate 200 , so that the connecting frame 400 can rotate freely relative to the placement frame 100 .

[0062] Specifically, if Figure 3 As shown, the connecting frame 400 includes a main frame 410 and a rotating disk 420; the rotating disk 420 is fixedly arranged on the two connecting plates 200; the main frame 410 is arranged in a U shape, and the two ends of the main frame 410 are respectively rotatably connected to the two rotating disks 420, and the rotating connection method can adopt a rotating shaft, so that the main frame 410 can rotate around the rotating disk 420 relative to the placement frame 100.

[0063] One end of the cable 500 is connected to the connecting frame 400, and the other end of the cable 500 is connected to the fixing assembly 600. The fixing assembly 600 is used to be fixed on the riverbed to fix the placement frame 100 on the upstream side of the bridge pier. After the fixing assembly 600 is fixed on the riverbed, the supporting force generated acts on the connecting frame 400 through the cable 500, thereby stabilizing the position of the placement frame 100.

[0064] In an optional embodiment, the fixing assembly 600 includes a fixing rod 610 and a connecting plate 620; the connecting plate 620 is spirally shaped and fixedly connected to the outer surface of the fixing rod 610. The spiral connecting plate 620 can improve the installation firmness of the fixing rod 610.

[0065] In an optional embodiment, one end of the cable 500 is rotatably connected to the top of the fixing rod 610 , so that the cable 500 can rotate relative to the fixing rod 610 around the axis of the fixing rod 610 .

[0066] Specifically, the fixing assembly 600 also includes a connecting ring 630; the connecting ring 630 is in the shape of a circular ring, and the connecting ring 630 is rotatably connected to the top of the fixing rod 610; the end of the cable 500 close to the fixing rod 610 is bent to form a hook, and the hook is hung on the connecting ring 630. Since the connecting ring 630 can rotate freely, the cable 500 can rotate around the fixing rod 610.

[0067] In an optional embodiment, if Figure 4 , Figure 5 As shown, the fixing assembly 600 also includes a fixing block 640 and a limiting block 650; the top of the limiting block 650 is connected to the fixing block 640, and the connecting ring 630 is arranged on the fixing block 640; the limiting block 650 is rotatably connected to the fixing rod 610, and the fixing rod 610 is configured to limit the movement of the limiting block 650.

[0068] Specifically, the limit block 650 includes a rotating column 651 and a disk 652 connected to each other; the rotating column 651 and the disk 652 are inverted T-shaped, that is, the disk 652 is connected to the bottom of the rotating column 651, and the outer diameter of the disk 652 is larger than the outer diameter of the rotating column 651.

[0069] A rotating groove and a chuck groove that are interconnected are provided in the fixed rod 610; the rotating groove and the chuck groove are in an inverted T shape, the rotating column 651 is provided in the rotating groove, and the disk 652 is provided in the chuck groove, and the groove width of the chuck groove is larger than the groove width of the rotating groove, so that the rotating column 651 and the disk 652 can only rotate but cannot move.

[0070] By providing the connecting frame 400 and the connecting ring 630 , the placing frame 100 as a whole can float up and down and left and right along with the water flow, thereby improving the applicability.

[0071] It should be noted that since the limit block 650 is an inverted T-shape, and the rotating groove and the chuck groove are placed in the fixed rod 610, during the molding process of the fixed rod 610, the rotating column 651 needs to be placed in the rotating groove and the disc 652 needs to be placed in the chuck groove to ensure that after the fixed rod 610 is molded, the limit block 650 is in the groove of the fixed rod 610.

[0072] Working principle: When placing the placement rack 100 for use, first open the connecting plate 200 to place the counterweight ball 300 in the placement rack 100, and then fix the connecting plate 200 on the placement rack 100 through the screw rod 710 and the screw sleeve 720 to achieve the placement and support effect of the counterweight ball 300, and then place the placement rack 100 at the specified position, and finally use the tool to rotate the fixing rod 610, under the action of the connecting plate 620, it is convenient to install the fixing rod 610 in the corresponding position, and under the action of the connecting plate 620, the installation firmness of the fixing rod 610 is improved. Its principle is consistent with the connection method of the bolt. Under the connection of the limit block 650 and the fixing block 640, the connection of the connecting ring 630 and the cable 500 enables the fixing rod 610 to pull the placement rack 100 under the action of the cable 500, thereby improving the stability of the placement rack 100.

[0073] The bridge pier anti-scour structure provided in this embodiment has the following beneficial effects:

[0074] The fixing assembly 600 is fixed on the riverbed. Since the fixing assembly 600 is connected to the connecting frame 400 through the cable 500, and the connecting frame 400 is rotatably connected to the connecting plate 200, the placement frame 100 can be fixed on the upstream side of the pier, thereby improving the stability of the placement frame 100.

[0075] Furthermore, the connecting plate 200 blocks the opening of the placement rack 100, and restricts the plurality of weighted balls 300 in the placement rack 100. Since the connecting plate 200 and the placement rack 100 are detachably connected, it is convenient to replace the weighted balls 300 in the placement rack 100, thereby improving the overall applicability.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
