Abstract
Description
Technical Field
[0001] This application relates to a river cleaning device. Background Technology
[0002] Small tributaries, especially those flowing from cities or parks into secondary rivers, often contain significant amounts of pollutants. Currently, these are primarily separated by filtration nets. However, these nets are prone to pollutant accumulation, making them difficult to clean and potentially raising water levels in the tributaries. This can cause pollutants to overflow the nets and enter the secondary rivers, increasing the burden on secondary river pollution control. Therefore, it is necessary to improve existing nets to minimize these problems. Utility Model Content
[0003] To address the aforementioned problems, this application proposes a river cleaning device, comprising an arc-shaped net, an annular guide frame on the upstream side of the arc-shaped net, and traction ropes on both sides of the annular guide frame. The traction ropes are connected to a bank-side fixing component mounted on the riverbank. The bank-side fixing component includes a fixed base plate, within which a sliding cavity is formed. A sliding block is slidably mounted within the sliding cavity. The traction ropes are fixedly connected to the sliding block on the opposite side of the annular guide frame. This application uses an arc-shaped net for centralized collection, increasing the amount of floating pollutants that can be collected. The sliding block fixed by the traction rope indicates the tension on the arc-shaped net. When the tension is high, timely cleaning can be performed to prevent overflow.
[0004] Preferably, the sliding block includes a rectangular block located in the middle, sliding wing plates are provided on both sides of the rectangular block, a side baffle that cooperates with the sliding block is provided on the outside of the sliding cavity, and a plurality of abutment springs that cooperate with the rectangular block are provided on the inside of the sliding cavity; the number of traction ropes is two, and they are respectively hung on the sliding wing plates.
[0005] Preferably, the rectangular block is provided with a snap-fit groove at the position corresponding to the position where it abuts the spring.
[0006] Preferably, the fixed base plate is provided with a plurality of side connecting plates, which are fixed to the riverbank by anchor bolts.
[0007] Preferably, the annular inlet frame includes a bottom plate, vertical plates on both sides of the bottom plate, a mounting groove in each vertical plate, a mounting plate in which a mounting plate is mounted, and a top plate between the mounting plates. Lateral connecting plates are provided on the sides of the mounting plates, and several lateral hooks are provided on the sides of the arc-shaped mesh for attaching to the lateral connecting plates. The mounting plates and vertical plates are fixedly connected by locking bolts. This application uses lateral hooks and bottom hooks to connect the arc-shaped mesh to the bottom plate and the lateral connecting plates on the mounting plates, ensuring the structural stability of the arc-shaped mesh and thus providing better collection capacity for floating pollutants.
[0008] Preferably, a bottom hanging plate is provided at the bottom of the vertical plate, and a bottom hook that cooperates with the bottom hanging plate is provided at the bottom of the arc-shaped mesh.
[0009] Preferably, the traction rope is fixedly connected to the side of the vertical plate.
[0010] Preferably, the arc-shaped net includes two opposing side support rods, with the net body positioned between the side support rods. A bottom rod is also positioned between the side support rods, and the bottom rod is connected to the bottom plate via a matching bottom positioning hook and a bottom positioning ring. This application uses the bottom rod and side support rods to form the support structure for the entire arc-shaped net. Combined with the impact of upstream water flow, this allows the net body to be impacted, forming the entire arc-shaped interception structure. The overall structure of the arc-shaped net is simple and inexpensive.
[0011] Preferably, the lateral hooks and bottom hooks are mounted on the side support rods of the net; and several buoyancy balls are mounted on the top of the net body.
[0012] This application can bring the following beneficial effects:
[0013] 1. This application uses an arc-shaped net for centralized collection, which increases the amount of floating pollutants that can be collected. Then, the tension of the arc-shaped net is indicated by a sliding block fixed by a traction rope. When the tension is large, it can be cleaned in time to avoid overflow.
[0014] 2. This application uses lateral hooks and bottom hooks to connect the curved net to the bottom plate and the lateral connecting plate on the mounting plate, which can ensure the structural stability of the curved net and thus have a better ability to collect floating pollutants.
[0015] 3. This application uses the bottom rod and the side support rod of the net to form the support structure of the entire arc-shaped net. With the impact of the upstream water flow, the net body can be impacted to form the entire arc-shaped interception structure. The overall structure of the arc-shaped net is simple and the cost is low. Attached Figure Description

The traction rope 3 is fixed to the sliding block 7 so that it can slide according to the magnitude of the tension. Thus, the position of the sliding block 7 can be used to indicate the magnitude of the tension it receives.
[0026] In the second embodiment, as Figure 1-6As shown, a river cleaning device includes an arc-shaped net 1, an annular guide frame 2 on the upstream side of the arc-shaped net 1, and traction ropes 3 on both sides of the annular guide frame 2.

A side baffle 9, cooperating with the sliding block 7, is provided on the outer side of the sliding cavity 6, and several abutment springs 10, cooperating with the rectangular block 8, are provided on the inner side of the sliding cavity 6. Two traction ropes 3 are provided, each hooked onto one of the sliding wing plates 11. The rectangular block 8 has a locking groove 12 corresponding to the abutment spring 10.

A mounting groove 17 is provided within each vertical plate 16, and an mounting plate 18 is mounted within the mounting groove 17. A top plate 19 is positioned between the mounting plates 18. A lateral connecting plate 20 is provided on the side of the mounting plate 18, and several lateral hooks 21 are provided on the side of the arc-shaped net 1, which are attached to the lateral connecting plate 20. The mounting plate 18 and the vertical plates 16 are fixedly connected by locking bolts. A bottom hanging plate 23 is provided at the bottom of the vertical plate 16, and a bottom hook 24, which cooperates with the bottom hanging plate 23, is provided at the bottom of the arc-shaped net 1.
