[0018] The riverway intercepting device provided by the utility model, when sundries in the riverway are intercepted by the first intercepting net, the scraping plate can be moved by the pulling assembly, and the sundries on the intercepting net can be effectively scraped by the scraping plate, because the scraping plate can cover the whole riverway width direction, so most of the sundries on the intercepting net can be cleaned at one time, and compared with manually cleaning the sundries one by one, the efficiency is greatly improved, the pulling assembly is arranged at one end of the crossbeam, and the operator only needs to operate the pulling assembly on one side of the riverway, so that the scraping plate can be controlled to slide on the crossbeam, thus it is avoided that the staff needs to enter the riverway or shuttle back and forth on the two banks of the riverway to clean the sundries, and the convenience and safety of the cleaning work are improved.
[0019] Further, the intercepting holes of the second intercepting net are larger than the intercepting holes of the first intercepting net, and this design enables the device to perform graded interception on the sundries in the riverway, so that larger sundries are first intercepted by the second intercepting net, and the impact on the first intercepting net is reduced, and the main intercepted sundries are intercepted by the first intercepting net.
[0020] Further, the sediment accommodating groove is located at the front side of the lower end of the second intercepting net and is fixed to the river bottom, the second intercepting net can intercept larger and heavier sundries, and the sundries fall into the sediment accommodating groove based on their own weight, so that the risk of flowing into the downstream and the impact on the first intercepting net are reduced.
[0021] Further, one pulling assembly is arranged at each end of the crossbeam, and the pulling ropes at the ends are fixedly connected with the scraping plates, so that the scraping plates can be pulled from both sides, when the scraping plates are located at the middle position of the crossbeam, the scraping plates are pulled to both sides respectively, so that the total amount of the intercepted sundries in single scraping is reduced, and the scraping is more flexible.
[0022] Further, the mounting grooves arranged on the crossbeam provide definite mounting positions for the first intercepting net and the second intercepting net, in the mounting process, the staff only needs to mount the first intercepting net and the second intercepting net in the mounting grooves respectively, so that the operation is simple and clear, this design makes the mounting process of the intercepting net more standardized, reduces the uncertainty and errors in the mounting process, and improves the mounting efficiency, and different intercepting nets with different intercepting holes can be replaced and used according to the sundry conditions in the riverway, so that the intercepting nets are convenient to disassemble and assemble.
[0023] Further, the rolling columns are rotatably arranged on both sides of the sliding block and are arranged above the convex columns, when the sliding block slides in the sliding hole, the rolling of the rolling columns can greatly reduce the friction between the sliding block and the convex columns, so that the scraping plate can move more smoothly on the cross beam during scraping, reducing the jam phenomenon caused by excessive friction, and the smooth sliding performance can ensure that the scraping plate always works effectively after cleaning a large amount of debris or long-term use, improving the efficiency of cleaning debris; the telescopic scraper can be telescopic in the vertical direction, in the actual river environment, the height of debris accumulation may be different, when encountering the condition that the debris accumulation is higher, the telescopic scraper can be elongated, so as to effectively scrape the debris at a higher position; when the debris accumulation is shallow, the telescopic scraper can be shortened to avoid damage to the interception net or excessive extrusion of the debris, the flexibility makes the scraping plate better adapt to various debris accumulation scenes, improving the comprehensiveness and accuracy of cleaning debris.

[0043] When the sundries in the river channel are intercepted by the first intercepting net 20, the scraping plate 50 is moved through the pulling assembly 60, and the scraping plate 50 can effectively scrape the sundries on the intercepting net; because the scraping plate 50 can cover the entire width direction of the river channel, most of the sundries on the intercepting net can be cleaned at one time, and the efficiency is greatly improved compared with cleaning the sundries one by one manually; the pulling assembly 60 is arranged at one end of the beam 10, and the operator only needs to operate the pulling assembly 60 on one side of the river channel to control the sliding of the scraping plate 50 on the beam 10, so that the worker does not need to enter the river channel or shuttle back and forth on both banks of the river channel to clean the sundries, thereby improving the convenience and safety of the cleaning work.
[0044] Among them, the related setting of the beam 10 is as follows:
[0045] In the optional solution of the embodiment, preferably, as shown in the figure, Figure 1 As shown, the fixing device comprises a fixing rod 40, and the lower end of the fixing rod 40 is a tapered tip 41. The tapered tip 41 at the lower end of the fixing rod 40 is designed to make the fixing device easier to insert into the ground of the river bank during installation. The tapered tip 41 is like a wedge, which can reduce the resistance during insertion. The worker only needs to align the fixing rod 40 with the installation position and use a certain impact force (such as hammering with a tool) to make the fixing rod 40 smoothly insert into the ground, thereby stably installing the beam 10 on the river channel. Compared with other shapes of the bottom, this design greatly improves the convenience of installation.
[0046] Specifically, the two ends of the beam 10 are fixed to the ground through two fixing rods 40 respectively.
[0047] In the optional solution of the embodiment, preferably, as shown in the figure, Figure 1As shown, the number of pulling assemblies 60 is 2, and one pulling assembly 60 is arranged at each end of the crossbeam 10; the pulling assembly 60 has a pulling rope 64 capable of being reeled in and released, and the ends of the pulling rope 64 are fixedly connected with the scraping plate 50. One pulling assembly 60 is arranged at each end of the crossbeam 10, and the ends of the pulling rope 64 are fixedly connected with the scraping plate 50, which enables the scraping plate 50 to be pulled on both sides, for example, when the scraping plate 50 is located at the middle position of the crossbeam 10, it is pulled on both sides respectively, which can reduce the total amount of intercepted sundries in a single scraping, and makes the scraping more flexible.

The rotating shaft 62 is rotated through the rocker 63, which makes the worker more labor-saving when pulling the scraping plate 50. Compared with directly pulling the pulling rope 64 with hands, the rocker 63 can generate a larger torque with a smaller force through the principle of lever, so as to more easily rotate the rotating shaft 62 and realize the reeling in and releasing of the pulling rope 64. In the case of frequent operation of the pulling assembly 60 for cleaning sundries, this labor-saving operation mode can reduce the labor intensity of the worker.

The installation slots provided on the crossbeam 10 provide clear installation positions for the first intercepting net 20 and the second intercepting net 30, and during the installation process, the workers only need to install the first intercepting net 20 and the second intercepting net 30 corresponding to one installation slot, which is simple and easy to operate. This design makes the installation process of the intercepting net more standardized, reduces the uncertainty and errors in the installation process, and improves the installation efficiency; and different intercepting nets with different intercepting holes can be replaced and used according to different river debris conditions, which is convenient for disassembly and assembly.
