Description

Technical Field

[0001] The invention relates to the technical field of ecological environment engineering, and in particular to a device for intercepting floating objects on a water surface. Background Art

[0002] Water hyacinth, scientifically known as Eichhornia crassipes, also known as Eichhornia crassipes, is a perennial floating herb, now widely distributed in rivers, lakes, ponds and ditches in the Yangtze River Basin, the Yellow River Basin and various provinces in South China. Water hyacinth mainly reproduces asexually, but can also reproduce sexually. It has a strong reproductive capacity, especially when the temperature and other environmental conditions are suitable, the reproduction speed is very fast, and a new individual can grow every 5 days. In eutrophic water bodies, once introduced, water hyacinth often over-reproduces, which will not only cause hypoxia in the water body, reduce biodiversity, and further deteriorate water quality, but also block waterways, affecting flood discharge and navigation, as well as the normal operation of water treatment facilities and devices deployed in the water body. Because it is difficult to prevent and control, spreads rapidly, and causes serious harm, it has been listed as one of the world's top ten malignant weeds.

[0003] Physical control is currently the most commonly used and environmentally safe method for water hyacinth control, including manual salvage, mechanical salvage, interception and isolation, etc. Manual salvage is time-consuming and labor-intensive, and has low efficiency. With mechanical salvage, it is difficult for salvage boats to pass through waters where the water surface is severely covered or the water depth is shallow. For scattered distribution on large water surfaces, mechanical salvage consumes a lot of energy and has high control costs. The salvage method may result in incomplete salvage or the salvage speed is far behind the speed of water hyacinth reproduction and growth. Before the water hyacinth breaks out on a large scale in spring each year, intercepting and capturing the scattered water hyacinths in the water body, limiting them to a certain range, and then intensively salvaging and removing them is a low-cost, time-saving, effective and thorough method for controlling water hyacinth.

[0004] The existing water hyacinth interception device mainly has the function of blocking, and the main method is to block the water hyacinth on the upstream side of the device or in the upwind area of ​​the open water, such as the patents with the authorization announcement numbers of CN 106013022A and CN207828936U. Under this management idea, the water hyacinth is still in a state of continuous reproduction and expansion in situ after being blocked. Compared with the situation of flowing with the water flow or drifting around under the action of the wind, after being blocked, the water hyacinth is in a relatively stable environment and grows and reproduces faster. If it is not salvaged in time and cleaned up on shore, the biomass of the water hyacinth group may multiply several times within 10 days. In addition, when the wind direction changes or the water flow direction changes (such as tidal river channels), the blocked water hyacinth may be at risk of escape. Because it has a very strong ability to spread and diffuse, as long as a few individual plants escape, it may break out again.

[0005] In summary, it is particularly necessary to seek a device that can intercept water hyacinth floating on the surface of the water body with a high interception rate, limit its continued excessive reproduction after interception, and prevent its escape and secondary spread, for the prevention and control of water hyacinth.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] The present invention provides a floating object interception device 100, see Figures 1 to 6 , Figures 1 to 6 It is a schematic structural diagram of a water surface floating object interception device 100.

[0039] See also Figures 1 to 6 The surface floating object interception device 100 is used for intercepting and preventing surface floating objects in the water flow, and the surface floating object interception device 100 includes an interception device 1 and a blocking device 2. The interception device 1 is used to intercept surface floating objects, and includes a plurality of interception hollow buoys 11, a long connecting piece 12 connecting two adjacent interception hollow buoys 11, an interception buoy counterweight assembly 13, and an interception device pulling and fixing assembly 14. The plurality of interception hollow buoys 11 are distributed in series along the width direction of the water surface, and any two adjacent interception hollow buoys 11 are connected by the long connecting piece 12; the interception device pulling and fixing assembly 14 is arranged at both ends of the interception device 1 in the width direction of the water surface, so as to install the interception device 1 on a fixed surface.

[0040] The intercepting device 2 is used to intercept floating objects on the water surface, and includes a plurality of intercepting hollow buoys 21, a short connector 22 connecting two adjacent intercepting hollow buoys 21, an intercepting buoy counterweight assembly 23, and an intercepting device pulling and fixing assembly 24. The plurality of intercepting hollow buoys 21 are distributed in series along the width direction of the water surface, and any two adjacent intercepting hollow buoys 21 are connected by the short connector 22; the intercepting device pulling and fixing assembly 24 is arranged at both ends of the intercepting device 2 in the width direction of the water surface, and is used to install the intercepting device 2 on a fixed surface.

[0041] The longitudinal sections of the intercepting hollow buoy 11 and the blocking hollow buoy 21 are both arranged in a trapezoidal shape, and have a long bottom side and a short bottom side which are arranged opposite to each other.

[0042] In the interception device 1, the short bottom sides of the interception hollow buoys 11 are all arranged toward the incoming water side or upwind direction of the water surface, and the minimum spacing between any two adjacent interception hollow buoys 11 in the width direction of the water surface is greater than the length of the floating object on the water surface in the width direction of the water surface, and the distance of each long connecting member 12 above the water surface is greater than the distance of the top of the floating object on the water surface above the water surface.

[0043] In the intercepting device 2, the short bottom side of one of any two adjacent intercepting hollow buoys 21 is arranged toward the incoming water side or the upwind side of the water surface, and the short bottom side of the other intercepting hollow buoy 21 is arranged toward the backwater side or the downwind side of the water surface, and the spacing between any two adjacent intercepting hollow buoys 21 in the width direction of the water surface is smaller than the length of the floating object on the water surface in the width direction of the water surface, and the distance of each short connecting member 22 above the water surface is smaller than the distance of the top of the floating object on the water surface above the water surface.

[0044] In the technical solution of the present invention, floating objects on the water surface include harmful floating plants such as water hyacinth and surface garbage, and the floating object interception device 100 on the water surface includes an interception device 1 and a blocking device 2. The short bottom sides of the interception hollow buoys 11 of the interception device 1 are all set toward the incoming water side or upwind direction of the water surface, and are connected by a long connecting piece 12, so that a certain distance is left between two adjacent interception hollow buoys 11, forming a trumpet-shaped one-way channel that is easy for water hyacinth to enter but difficult to exit, and then by setting the height of the long connecting piece 12 relative to the water surface, the water hyacinth can pass through the area below the long connecting piece 12 under the action of water flow or wind and enter the downstream area of ​​the interception device 1. In this regard, the interception device 1 has an interception function. Can; and the short bottom sides of any two adjacent blocking hollow buoys 21 in the blocking device 2 are respectively arranged toward the incoming water side or upwind direction of the water surface and the back water side or downwind direction of the water surface, and are connected by a short connector 22, and then by setting the height of the short connector 22 relative to the water surface, the water hyacinth is blocked by the short connector 22, and cannot enter the downstream side area of ​​the blocking device 2 from the gap area between any two adjacent blocking hollow buoys 21 under the action of external forces such as water flow or wind. In this regard, the blocking device 2 has a blocking effect.

[0045] In addition, by providing the interception buoy counterweight assembly 13 and the interception device pulling and fixing assembly 14, the stability and wind and wave resistance of the interception hollow buoy 11 can be enhanced, and the interception hollow buoy 11 can remain floating on the water surface; and by providing the interception buoy counterweight assembly 23 and the interception device pulling and fixing assembly 24, the stability and wind and wave resistance of the interception hollow buoy 21 can be enhanced, and the interception hollow buoy 21 can remain floating on the water surface; thereby ensuring the interception effect of the interception device 1 and the interception device 2.

[0046] Furthermore, the surface floating object interception device 100 can be flexibly applied to various types of waters by selectively setting one interception device 1, or a combination of two interception devices 1, or a combination of an interception device 1 and a blocking device 2. For example, when applied to a general river, please refer to Figure 3 The surface floating object interception device 100 can be optionally provided with an interception device 1 and an interception device 2, wherein the interception device 1 and the interception device 2 are arranged at intervals in the downstream section of the river channel, wherein the interception device 1 is close to the upstream side of the river channel, and the interception device 2 is close to the downstream side of the river channel, and the water hyacinth plants scatteredly floating on the water surface of the upstream and middle reaches of the river channel drift to the upstream side of the interception device 1 under the conveying action of the water flow, and when the surface water flows through the gap between any two adjacent interception hollow buoys 11 of the interception device 1, the water flow is narrowed and the flow speed is accelerated, and the water hyacinth is brought into the middle area between the interception device 1 and the interception device 2 by the water flow with accelerated flow speed, and in the middle area The water hyacinth in the area continues to drift toward the intercepting device 2 under the action of the water flow. When it drifts to the upstream side of the intercepting device 2, it is intercepted by the intercepting device 2 and stays in the middle area. The water hyacinth individuals continue to grow and reproduce new individuals in the middle area, and the plant height and the diameter of the plant gradually increase. When the water flow rate slows down or the wind direction changes, the water hyacinth cannot escape from the middle area from the intercepting device 1 and the intercepting device 2. These water hyacinths intercepted in the middle area are salvaged and cleaned out of the water by water surface maintenance personnel; for example, when applied to still water areas such as ponds and lakes, the water hyacinths floating on the water surface are mainly dispersed and moved by the action of wind, please refer to Figure 5 The surface floating object interception device 100 can only select the interception device 1 for interception. The interception device 1 is installed in a corner downwind of the entire water surface, and the short bottom sides of the trapezoidal longitudinal cross-section of the interception hollow buoy 11 are all arranged toward the upwind direction. The water hyacinth plants floating on the water surface gradually drift to the upwind side of the interception device 1 under the action of wind, and reach the gap area between any two adjacent interception hollow buoys 11. Under the action of wind, they pass through and enter the area downwind of the interception device 1 and gradually gather for maintenance personnel to salvage.

[0047] It should be noted that the water surface floating object interception device 100 can confine the water hyacinth to a smaller spatial range. Therefore, when the water hyacinth grows and reproduces too quickly and the maintenance personnel fail to salvage it in time, the water surface floating object interception device 100 can inhibit the growth and reproduction of individual water hyacinths by utilizing the gradually increasing intraspecific competition within the population (competition for sunlight, nutrients, growth space, etc.), thereby preventing it from growing wildly without limits and increasing the difficulty and workload of salvage.

[0048] The surface floating object interception device 100 of the present technical solution has a simple structure, good effect of intercepting, blocking and controlling surface floating objects, high flexibility in use, wide application range and high practicality.

[0049] It should be noted that, in some embodiments of the present invention, the long connector 12 and the short connector 22 are both ropes, which serve to connect two adjacent buoys and enable the entire device to have better wave-riding performance.

[0050] It should also be noted that, in the present invention, the connection form between the intercepting hollow buoys 11 is not limited in specific form as long as it satisfies the connectivity and the wave-riding performance of the device. Of course, the connection form between the blocking hollow buoys 21 is also not limited. Figure 1 and Figure 2 In some embodiments of the present invention, the intercepting hollow buoy 11 and the blocking hollow buoy 21 are respectively provided with connecting rings 3 on both sides in the width direction of the water surface; both ends of the long connecting piece 12 and the two ends of the short connecting piece 22 are respectively provided with connecting hooks 4, which are used to adapt and buckle with the corresponding connecting rings 3 to facilitate disassembly and assembly, thereby improving the use flexibility of the surface floating object interception device 100.

[0051] Furthermore, the intercepting hollow buoy 11 and the blocking hollow buoy 21 are respectively provided with a plurality of connecting rings 3 on both side surfaces in the width direction of the water surface. The plurality of connecting rings 3 are spaced apart in the up-and-down directions on the vertical center line of the side surface to adjust the distance between the long connecting piece 12 and the short connecting piece 22 and the water surface, respectively. Thus, the setting positions of the long connecting piece 12 and the short connecting piece 22 can be selected correspondingly according to the actual height of the water surface and the height of the interception target, thereby greatly improving the practicability of the surface floating object interception device 100.

[0052] For details, please refer to Figure 1 and Figure 2 The intercepting buoy counterweight assembly 13 and the blocking buoy counterweight assembly 23 both include a plurality of counterweights, and the intercepting hollow buoy 11 and the blocking hollow buoy 21 are flexibly connected with counterweights, respectively. More specifically, the counterweights are gravel bags, gabions, or lead blocks.

[0053] For details, please refer to Figure 6The interception device pulling and fixing assembly 14 and the blocking device pulling and fixing assembly 24 both include a fixed pile 6, a floating connection member 7 and a buffer member 8. The fixed pile 6 is used to be fixedly installed on the fixed surface; one end of the two ends of the floating connection member 7 is sleeved with the fixed pile 6, and can slide flexibly in the up and down direction relative to the fixed pile 6; one end of the buffer member 8 is connected to the other end of the floating connection member 7, and the other end of the buffer member 8 is connected to the hollow buoys at both ends of the interception device 1 or the blocking device 2 in the water surface width direction, so that the interception device 1 and the blocking device 2 can float in the up and down direction and the horizontal direction with the change of water level and water speed through the floating connection member 7 and the buffer member 8 , keeping the interception device 1 and the blocking device 2 floating on the water surface, improving the wave-riding performance of the interception device 100, can effectively avoid the sudden increase in river flow velocity and flow during rainfall or the sudden increase in wind force on the water surface. Due to the water-blocking effect of the interception device 100, the water level in the upstream area of ​​the surface floating object interception device 100 rises and does not submerge the upper end surface of the interception hollow buoy 11 or the blocking hollow buoy 21, resulting in the water hyacinth floating on the water surface directly crossing over the top of the interception hollow buoy 11 or the blocking hollow buoy 21 with the water flow, thereby ensuring the interception efficiency of the interception device 1 and the blocking device 2 and improving the practicability of the surface floating object interception device 100.

[0054] It should be noted that the form of the buffer 8 is not limited. Specifically, in one embodiment of the present invention, the buffer 8 is a spring having an elastic and telescopic buffering function.

[0055] For details, please refer to Figure 1A one-way passing component 5 is provided between any two adjacent intercepting hollow buoys 11. The one-way passing component 5 is provided on the long connecting piece 12, and includes a plurality of swivel rods 51 and baffles 52. The plurality of swivel rods 51 are arranged on the long connecting piece 12 at equal intervals and fixed intervals in a series, and the distance between any two adjacent swivel rods 51 in the width direction of the water surface is smaller than the length of the floating object on the water surface in the width direction of the water surface; the baffle 52 is provided on the side of the swivel rod 51 close to the incoming water direction or the upwind direction along the width direction of the water surface, so that the swivel rod can only rotate around the long connecting piece toward the side away from the baffle, and the length of the baffle 52 in the width direction of the water surface is greater than the distribution length of the plurality of swivel rods 51 in the width direction of the water surface; in this way, the material density of the swivel rod 51 is greater than that of water, and it can sag naturally under the action of its own weight and maintain contact with the water surface. In a vertical state, it will not rotate and float under the impact force and buoyancy of the water flow. The spacing between any two adjacent hanging rods 51 is set so that the water hyacinth can only pass through the channel between the two retaining hollow buoys 11 after the hanging rods 51 are rotated as the water flow pushes them, but cannot directly pass back and forth freely through the gap between the two adjacent hanging rods 51; at the same time, the interception device 1 provided with a one-way passing component 5 can be used in waters with strong surface winds, rivers with high water flow velocities, or tidal river sections with reciprocating changes in water flow direction. In these scenarios, the possibility of the trapped water hyacinth individuals escaping from the channel between the adjacent retaining hollow buoys 11 under the action of wind or water flow can be reduced as much as possible, thereby further improving the interception effect of the surface floating object interception device 100, thereby further expanding the scope of application of the surface floating object interception device 100.

[0056] More specifically, when the surface floating object interception device 100 is applied to a tidal river, the surface floating object interception device 100 can selectively set two interception devices 1 provided with a one-way passing component 5, one of the two interception devices 1 is close to the upstream area of ​​the river channel, and the other is close to the downstream area of ​​the river channel. The water hyacinth plants scattered floating on the water surface of the upstream and middle reaches of the river channel drift to the upstream side of the interception device 1 located near the upstream area of ​​the river channel under the transport of water flow and wind. When the surface water flows through the gap area between any two adjacent interception hollow buoys 11, the water flow is narrowed and the flow rate is accelerated, and the water hyacinth is brought into the channel by the water flow with accelerated flow rate. And push the hanging rod 51 to rotate, pass through the intercepting device 1, and enter the middle area between the two intercepting devices 1. The water hyacinth individuals continue to grow and reproduce new individuals in the middle area, and the plant height and the diameter of the plant gradually increase. At this time, the water hyacinth can no longer escape from the middle area under the action of water flow and wind; when the river channel is reversed due to the influence of tides, the water hyacinth floating in the downstream of the two intercepting devices 1 and the estuary area passes through the two intercepting devices 1 and enters the middle area under the conveyance of the upstream water flow. These plants also continue to grow and reproduce new individuals, and can no longer escape from the middle area under the action of water flow and wind.

[0057] It should be noted that when applied to general rivers, if the flow rate of the river is greater than 0.5m / s, preferably, the interception device 1 adds a one-way passage component 5 to further reduce the probability of the intercepted water hyacinth individuals escaping from the interception device 1 under the action of wind or water flow.

[0058] In addition, when applied to still water bodies such as ponds and lakes, if the wind force level in the water body reaches level three or above for at least 20% of the time in the season, the interception device 1 is provided with a one-way passage component 5 to further reduce the probability of the intercepted water hyacinth individuals escaping from the interception device 1 under the action of wind or water flow.
