Description

Technical Field

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

[0002] In many ditches and small rivers, the accumulation of garbage and silt is a common problem. The sources of garbage are wide-ranging, including household waste, agricultural production waste, and floating objects washed down from upstream. These garbage not only affect the beauty of the river, but also cause water pollution and damage the water ecological environment. The accumulation of silt will reduce the water-passing section of the river, reduce the flood-carrying capacity of the river, increase the risk of flood disasters, and also affect the living environment of aquatic organisms in 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 silt continuously entering the river. Some simple pollution-blocking facilities have a single structure and can only intercept larger volumes of garbage. They are powerless against small garbage and silt, 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 a poor sand removal effect. Therefore, this field is in urgent need of a pollution 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 silt, 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 dirt 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 on 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, 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, a sealing plate is installed on the upper end of the frame, and the sealing plate is used to be installed on 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 floating balls and long floats that are alternately connected.

[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.

[0016] The pollution and sand blocking device provided by the present invention connects an interception net and a sand blocking plate under a float. Under the action of a counterweight, the interception net can effectively intercept solid domestic waste. 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 be changed into an arc shape. When the water flow carries sediment and sand through the sand blocking plate, the arc surface guides the water flow to change direction, so that after the sediment particles collide with the sand blocking plate, they flow smoothly into the river bottom along the arc shape, are separated from the water flow, and then enter the collecting trough for collection. After the sediment in the collecting trough is collected to a certain extent, it can be hoisted by a hoisting device, and then a sealing plate is installed at the inlet of the collecting trough to prevent the sediment from flowing out.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 dirt 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 so that the pollution-blocking device will 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 can be connected by hinges. Under the impact of water flow, the sand blocking plate 4 can change into an arc shape. The sand blocking plate 4 and the riverbed form a structure with a gradually decreasing space, which causes the water flow to be squeezed, and the flow velocity of the lower layer is higher than that of the upper layer, bringing the suspended sediment to the lower layer to become the bed sediment, and finally enters the collection tank 7. Due to the arc structure of the sand blocking plate 4, the fluid can smoothly transition to the collection tank 7 without directly impacting the riverbed, which causes 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 water flow direction, so as to effectively intercept solid domestic waste of different sizes, ranging 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 provided on the inner side of the frame 1, and the integrated sensor 11 integrates a water quality sensor, a flow sensor and a sediment content sensor. The water quality sensor monitors the changes in river water quality in real time, the flow sensor monitors the water flow velocity, and the sediment content sensor monitors the sediment concentration. Each sensor monitors various parameters of water quality in real time, and feeds back to the terminal platform through a wireless transmission module, providing accurate data support for river management. When the parameter exceeds the set threshold, a reminder alarm is issued to facilitate timely response measures.

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

[0037] In this embodiment, the float 2 includes alternately connected float balls 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 collecting tank 7 through the slings 8. The outer side surface of the slot side wall of the collecting tank 7 is provided with a vertical slide rail 16, and the inner sides of both ends of the sealing plate 9 are provided with a slide groove 17 that cooperates with the vertical slide rail 16. When the collecting tank 7 needs to be cleaned, the four winches 15 operate synchronously, and the collecting tank 7 is pulled up from under the water surface through the slings 8. When the collecting tank 7 is pulled up to below the sealing plate 9, the slide groove 17 is aligned with the vertical slide rail 16, and then the collecting tank 7 is continued to be lifted until the bottom of the sealing plate 9 abuts against the inner bottom surface of the collecting tank 7, the inlet of the collecting tank 7 is blocked, and then the collecting tank 7 can be hoisted onto a truck by a crane, and the truck is transported to a designated location for processing.

[0039] In this embodiment, a plurality of counterweights 5 are provided, which are arranged at equal intervals along the length direction of the interception net 3 to ensure that the interception net 3 and the sand blocking plate 4 are not washed away by the water flow, thereby ensuring the stability of the interception device. The counterweight 5 can be selected as a lead sinker. The connecting rope between the lead sinker and the interception net 3 has a certain flexibility, which can buffer the impact force of the water flow on the interception net 3 and the sand blocking plate 4 to a certain extent, further improving the stability and reliability of the device.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
