Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and environmental protection equipment, in particular to a pollution and sand blocking device. Background Art

[0002] The accumulation of garbage and silt is a common problem in many ditches and small rivers. The garbage comes from a wide range of sources, including household waste, agricultural waste, and floating debris washed down from upstream. This waste not only degrades the aesthetics of the river but also pollutes the water and damages the aquatic ecosystem. Sediment accumulation reduces the waterway's flow-through area, reducing its capacity to carry water, increasing the risk of flooding, and impacting the habitat of aquatic life within the river.

[0003] At present, the management methods for artificial ditches and small and medium-sized rivers are relatively limited, and there is a lack of devices with both pollution and sand blocking functions. Traditional manual cleaning methods are inefficient and costly, and cannot fundamentally solve the problem of garbage and sediment continuously entering the river. Some simple garbage interception facilities have a single structure and can only intercept larger volumes of garbage. They are powerless against small garbage and sediment, and are easily washed away when the water flow is large, and have poor stability. Traditional trash racks are easy to clog, and manual cleaning is inefficient; some sand blocking devices are easy to turn under the impact of water flow or cannot effectively disperse the impact force of the water flow, resulting in insignificant sand removal effect. Therefore, this field is in urgent need of a garbage and sand blocking device to solve the problem of poor management effect of existing technologies on artificial ditches and small and medium-sized rivers. Summary of the Invention

[0004] The purpose of the present invention is to provide a pollution and sand blocking device to solve the problems existing in the above-mentioned prior art, which can meet the management needs of artificial ditches and small and medium-sized rivers, effectively intercept garbage and sediment, has strong stability, and reduces labor costs.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides a pollution and sand blocking device, comprising a frame, a sediment collecting device, an intercepting device and a lifting device, the intercepting device comprising a float, an intercepting net and a sand blocking plate, the float is fixed to the frame, the upper end of the intercepting net is connected to the float, the lower end of the intercepting net is connected to a counterweight block, the upper end of the sand blocking plate is connected to the lower end of the intercepting net, the sand blocking plate comprises a plurality of sand blocking plate units hingedly connected in sequence along the height direction, the sediment collecting device comprises a collecting trough, the collecting trough is arranged on the downstream side of the intercepting device, the collecting trough is provided with an inlet on the side facing the incoming flow, the collecting trough is connected to the lifting device through a sling, the lifting device is fixedly installed on the frame, and a sealing plate is installed on the upper end of the frame, and the sealing plate is used to be installed at the inlet of the collecting trough to seal it.

[0007] In one embodiment, the interception net includes a plurality of interception net layers arranged in sequence, and the mesh size of each interception net layer gradually decreases along the direction of water flow.

[0008] In one embodiment, the upper end of the interception net is connected to the float via a hanging ring.

[0009] In one embodiment, an integrated sensor is fixedly provided on the inner side of the frame, and the integrated sensor integrates a water quality sensor, a flow sensor, and a sediment content sensor.

[0010] In one embodiment, the bottom of the collecting tank is an arc-shaped surface, and the arc-shaped surface faces the incoming flow direction.

[0011] In one embodiment, the float comprises alternately connected float balls and long floats.

[0012] In one embodiment, the hoisting device includes four winches, and the four winches are respectively connected to the four corners of the collecting tank through slings.

[0013] In one embodiment, there are multiple counterweights, which are arranged at equal intervals along the length of the interception net.

[0015] Compared with the prior art, the present invention has achieved the following technical effects:

[0016] The sewage and sand blocking device provided by the present invention connects the interception net and the sand blocking plate under the float. Under the action of the counterweight block, the interception net can effectively intercept solid domestic garbage. The sand blocking plate is a segmented structure, and each sand blocking plate unit is hingedly connected. Under the impact of water flow, the sand blocking plate can change into an arc shape. When the water flow carries sediment and flows through the sand blocking plate, the arc surface guides the water flow to change direction, so that the sediment particles collide with the sand blocking plate and then flow smoothly into the river bottom along the arc shape, separated from the water flow, and then enter the collection trough for collection. After the sediment in the collection trough is collected to a certain extent, it can be lifted by a lifting device, and then a sealing plate is installed at the inlet of the collection trough to prevent the sediment from flowing out.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a pollution and sand blocking device to solve the problems existing in the prior art, meet the management needs of artificial ditches and small and medium-sized rivers, effectively intercept garbage and silt, have strong stability, and reduce labor costs.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 7 As shown, this embodiment provides a pollution and sand blocking device, including a frame 1, a sediment collecting device, an intercepting device and a lifting device, the intercepting device including a float 2, an intercepting net 3 and a sand blocking plate 4, the float 2 is fixed on the frame 1, the upper end of the intercepting net 3 is connected to the float 2, the lower end of the intercepting net 3 is connected to a counterweight 5, the upper end of the sand blocking plate 4 is connected to the lower end of the intercepting net 3, the sand blocking plate 4 includes a plurality of sand blocking plate units 6 hingedly connected in sequence along the height direction, the sediment collecting device includes a collecting trough 7, the collecting trough 7 is arranged on the downstream side of the intercepting device, the collecting trough 7 is provided with an inlet on the side facing the incoming flow, the collecting trough 7 is connected to the lifting device through a sling 8, the lifting device is fixedly installed on the frame 1, and a sealing plate 9 is installed on the upper end of the frame 1, the sealing plate 9 is used to be installed on the inlet of the collecting trough 7 to seal it.

[0030] The frame 1 provides an installation and support carrier for other components in the device. When the water level rises or falls, the float 2 has sufficient buoyancy to make the pollution-blocking device rise and fall with the rise and fall of the water level, ensuring that the interception net 3 always remains near the water surface so that it can be used to block debris, and the sand-blocking plate 4 always moves with the movement of the interception net 3 to play its sand-blocking role.

[0031] The sand-blocking plate units 6 are hingedly connected to each other. Under the impact of water flow, the sand-blocking plates 4 can change into an arc shape, forming a gradually decreasing space between the sand-blocking plates 4 and the riverbed. This causes the water flow to be squeezed, and the flow velocity in the lower layer is higher than that in the upper layer. This carries the suspended sediment to the lower layer as bedload, and finally enters the collection trough 7. Due to the arc structure of the sand-blocking plates 4, the fluid can smoothly transition to the collection trough 7 without directly impacting the riverbed, which would cause the bed sand to be impacted and add more sediment.

[0032] The frame 1 is made of corrosion-resistant materials, such as high-strength water-resistant alloy or corrosion-resistant engineering plastic, which can effectively resist the erosion of river water and extend the service life of the device.

[0033] In this embodiment, the interception net 3 includes a plurality of interception net layers arranged in sequence, and the mesh size of each interception net layer gradually decreases along the direction of water flow, so as to effectively intercept solid domestic waste of different sizes, from large floating objects to fine debris.

[0034] In this embodiment, the upper end of the interception net 3 is connected to the float 2 through a lifting ring 10. When replacing the interception net 3, the interception net 3 is directly removed from the lifting ring 10, which facilitates the disassembly and assembly of the interception net 3.

[0035] In this embodiment, an integrated sensor 11 is fixedly mounted inside the frame 1. This integrated sensor 11 houses a water quality sensor, a flow sensor, and a sediment content sensor. The water quality sensor monitors changes in river water quality in real time, the flow sensor monitors water velocity, and the sediment content sensor monitors sediment concentration. Each sensor monitors various water quality parameters in real time and transmits feedback to the terminal platform via a wireless transmission module, providing accurate data support for river management. When a parameter exceeds a set threshold, an alert is issued, facilitating timely response measures.

[0036] In this embodiment, the bottom of the collecting trough 7 is an arcuate surface 12, which faces the incoming flow direction and can buffer the incoming flow carrying sediment, thereby reducing the impact on the original shape of the river.

[0037] In this embodiment, the float 2 includes alternately connected floats 13 and long floats 14, which provide buoyancy for the interception net 3 and the sand blocking plate 4, and cooperate with the counterweight block 5 to ensure that the interception net 3 and the sand blocking plate 4 can function stably in the water.

[0038] In this embodiment, the hoisting device includes four winches 15, and the four winches 15 are respectively connected to the four corners of the collection tank 7 through slings 8. The outer side surface of the slot side wall of the collection tank 7 is provided with a vertical slide rail 16, and the inner side of both ends of the sealing plate 9 is provided with a slide 17 that cooperates with the vertical slide rail 16. When the collection tank 7 needs to be cleaned, the four winches 15 run synchronously, and the collection tank 7 is pulled up from under the water surface through the sling 8. When the collection tank 7 is pulled up to the bottom of the sealing plate 9, the slide 17 is aligned with the vertical slide rail 16, and then the collection tank 7 is continued to be lifted until the bottom of the sealing plate 9 abuts against the inner bottom surface of the collection tank 7, the inlet of the collection tank 7 is blocked, and then the collection tank 7 can be hoisted onto a truck by a crane, and transported to a designated location for processing by the truck.

[0039] In this embodiment, multiple counterweights 5 are provided, evenly spaced along the length of the interception net 3. This prevents the interception net 3 and sand blocking plates 4 from being swept away by the current, thus ensuring the stability of the interception device. Counterweights 5 can be plumb bobs. The flexible cord connecting the plumb bob to the interception net 3 can mitigate the impact of the current on the interception net 3 and sand blocking plates 4 to a certain extent, further improving the stability and reliability of the device.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
