Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pollution prevention and control facilities, and in particular relates to a pollution-blocking curtain used for water pollution prevention and control. Background Art
[0002] Trash curtains are mainly used in scientific research and water projects such as lake pollution prevention and control, water body restoration, aquatic system reconstruction, sludge dredging, filling operations, diversion and algae prevention. During port construction and dredging operations, the spread of turbid mud flow causes harm to the ecological environment and aquaculture. Water body enclosures isolate local construction waters from non-operating areas to prevent pollution from spreading, effectively protecting the ecological environment and marine aquaculture areas.
[0003] Existing dirt-blocking curtains are usually composed of an upper float, a lower skirt, and counterweights at appropriate positions. The float generates buoyancy, the skirt acts as a dirt-blocking device in the water, and the counterweight is used to suspend the skirt in the water. When constructing a complete dirt-blocking curtain facility, multiple dirt-blocking curtain units are spliced in sequence. The dirt-blocking curtain of the aforementioned structure has the following problems: First, the skirt portion has poor stability in the water, and there is often a problem of pollutant spillage caused by part of the dirt-blocking curtain skirt completely floating on the water surface; second, the constructed dirt-blocking curtain has poor ability to maintain its position in the water, and will shift when affected by water flow in flowing waters. In summary, it is necessary to develop and design a new type of dirt-blocking curtain structure to solve the aforementioned technical problems. Utility Model Content
[0004] The utility model aims to provide a dirt-blocking curtain for water pollution prevention and control, which improves the posture and position keeping capabilities of the dirt-blocking curtain in the water body and achieves a better dirt-blocking effect.
[0005] The technical solution adopted by the utility model is: a dirt-blocking curtain for water pollution prevention and control, which is composed of dirt-blocking curtain monomers spliced in sequence; the dirt-blocking curtain monomer comprises a floating body located at the top and a skirt located at the bottom, a transverse connecting rope is provided at the top edge of the floating body, a transverse load-bearing chain is provided at the bottom edge of the skirt, and a counterweight block is suspended by a suspension rope below the load-bearing chain; the adjacent end edges of two adjacent dirt-blocking curtain monomers are overlapped and connected by binding with a connecting chain, a vertical supporting steel pipe is also provided at the overlapping edge position, the supporting steel pipe passes through the connecting chain and the top of the connecting chain is fixedly connected to the supporting steel pipe, the adjacent ends of the connecting ropes of two adjacent dirt-blocking curtain monomers are bound and connected, and the ends of the load-bearing chains of two adjacent dirt-blocking curtain monomers are connected by a U-shaped fastener; it also includes an anchor cable and an anchor arranged on the side of the water-facing surface, and the upper end of the anchor cable is fixedly connected to the upper end of the supporting steel pipe.
[0006] Preferably, the end edges of the float and the skirt are sewn together to form an end seal, and a plurality of end connecting holes are provided on the end seal from top to bottom, the adjacent end seals of two adjacent dirt-blocking curtain monomers are overlapped and the end connecting holes overlap, and the connecting chain is zigzagly inserted into the end connecting holes.
[0007] Preferably, the float comprises a cylindrical outer bag body, a suture is arranged at the top edge of the outer bag body, a plurality of floats are arranged in the space below the suture inside the outer bag body, and the main part of the connecting rope is located in the tubular channel above the suture.
[0008] Preferably, the bottom edge of the skirt is folded upward and sewn to form a tubular channel, and the main body of the load-bearing chain is located in the tubular channel.

[0012] The advantages and positive effects of the utility model are:
[0013] The utility model provides a pollution-blocking curtain for water pollution prevention and control with a reasonable structural design. Compared with the existing pollution-blocking curtain facilities, the pollution-blocking curtain of the utility model uses connecting chains to tie and connect the pollution-blocking curtain monomers at the overlapping edge positions and sets vertical supporting steel pipes at the overlapping edge positions. Since the connecting chains themselves have a certain weight, the connecting chains can be fully stretched in the vertical direction on the supporting steel pipes, so the skirt of the pollution-blocking curtain monomer can be fully suspended and spread in the water body, effectively avoiding the problem of being unable to effectively intercept pollutants due to the floating of the skirt in the water body. The load-bearing chains and counterweights set at the bottom of the skirt further enhance the technical effect of suspending and spreading the skirt in the water body.
[0014] The supporting steel pipe can stand upright in the water (in scenes with greater water depth) to produce a plumb bob effect or penetrate into the bottom mud (in scenes with less water depth) to produce a fixing effect. Therefore, the dirt-blocking curtain in the utility model can better maintain its position in the water body and has a stronger ability to resist the action of water flow. The anchor cable and anchor arranged on the side facing the water further enhance the position-keeping ability of the dirt-blocking curtain in the water body. In summary, the dirt-blocking curtain in the utility model has strong posture-keeping ability and position-keeping ability in the water body, achieving a better dirt-blocking effect.

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.
[0020] See also Figure 1 and Figure 2 The utility model of the pollution-blocking curtain for water pollution prevention and control is composed of pollution-blocking curtain monomers spliced in sequence, and the complete pollution-blocking curtain facility constructed can be a closed ring (to prevent internal pollutants from spreading to the external area) or a straight line (to prevent pollutants from transferring from one side to the other side).
[0021] The dirt-blocking curtain monomer includes a floating body 1 located at the top and a skirt body 5 located at the bottom. A transverse connecting rope 2 is provided at the top edge of the floating body 1, and a transverse load-bearing chain 7 is provided at the bottom edge of the skirt body 5. A counterweight 6 is suspended by a suspension rope 10 below the load-bearing chain 7. The floating body 1 is used to provide buoyancy, and the skirt body 5 is suspended in the water body to intercept pollutants. The connecting rope 2 is used for the top connection between adjacent dirt-blocking curtain monomers, and the load-bearing chain 7 and the counterweight 6 below are used to pull the skirt body 5 downward, so that the skirt body 5 is fully suspended and stretched in the water body to achieve a better dirt-blocking effect.
[0022] In this embodiment, the end edges of the float 1 and the skirt 5 are sewn together to form an end sealing edge 3, and a plurality of end connecting holes 4 are provided on the end sealing edge 3 from top to bottom. Each end connecting hole 4 is used for smooth splicing and connection between adjacent dirt-blocking curtain monomers.
[0023] like Figure 1As shown in the figure, the floating body 1 includes a cylindrical outer bag body, a suture line is set at the top edge of the outer bag body, and multiple buoys are set in the space inside the outer bag body and below the suture line. The main part of the connecting rope 2 is located in the tubular channel above the suture line, and both ends are exposed from the tubular channel for a certain length. In this way, the multiple buoys are confined inside and will not be arbitrarily displaced. The radial dimension of the tubular channel is slightly larger than the radial dimension of the connecting rope 2, so the connecting rope 2 will not be arbitrarily displaced or fall out.
[0024] In this embodiment, the bottom edge of the skirt 5 is folded upward and sewn to form a tubular channel, and the main part of the load-bearing chain 7 is located in the tubular channel, and the two ends of the load-bearing chain 7 are exposed from the tubular channel for a certain length. The radial dimension of the tubular channel is slightly larger than the radial dimension of the load-bearing chain 7, so the load-bearing chain 7 will not be displaced or fall out arbitrarily. The upper end of the sling 10 is fixedly connected to the chain petal of the load-bearing chain 7 by a strap, and the lower end of the sling 10 is fixedly connected to the counterweight 6. The counterweight 6 can be a prefabricated concrete block or a stone, and should be reliably connected to the sling 10 to avoid falling off.
[0025] The bottom edge of the float 1 and the top edge of the skirt 5 are fixedly connected by a reinforcing belt 8, and the reinforcing belt 8 is sewn to the bottom edge of the float 1 and the top edge of the skirt 5 at the same time. Generally, the top edge of the skirt 5 can be directly sewn to the bottom edge of the cylindrical bag body of the float 1, but this connection method has poor reliability. When the dirt-blocking curtain is washed by water flow, it is easy to tear at the sewn connection position. The above problem can be solved by setting the reinforcing belt 8, which covers the connection position between the float 1 and the skirt 5, and multiple sutures are set on the reinforcing belt 8 to ensure the reliability of the connection.
[0026] The adjacent end edges of two adjacent dirt-blocking curtain monomers are overlapped and tied and connected by a connecting chain 12. Specifically, the adjacent end sealing edges 3 of two adjacent dirt-blocking curtain monomers are overlapped and the end connection holes 4 overlap, and the connecting chain 12 is zigzagly penetrated in the end connection hole 4. The function of overlapping the end sealing edges 3 is to avoid the formation of gaps between adjacent dirt-blocking curtain monomers, improve the continuity of the constructed dirt-blocking curtain facility, and prevent pollutants from passing through gaps at any position, thereby improving the effect of intercepting pollutants.
[0027] A vertical support steel pipe 11 is further provided at the overlapping edge of two adjacent dirt-blocking curtain units. The support steel pipe 11 passes through the connecting chain 12 and the top of the connecting chain 12 is fixedly connected to the support steel pipe 11 (for example, fixed by binding with a strap). Figure 2The relative position relationship between the connecting chain 12 and the supporting steel pipe 11 is given in the figure. After the end sealing edges 3 of the dirt-blocking curtain monomers are stacked, the connecting chain 12 is zigzag inserted into the overlapping end connection holes 4, and then the supporting steel pipe 11 is inserted into the stacking area (the supporting steel pipe 11 should be located between the two stacked end sealing edges 3). Since the connecting chain 12 itself has a certain weight, the connecting chain 12 can be smoothly unfolded downward on the supporting steel pipe 11, so that the skirt 5 is fully suspended and unfolded in the water.
[0028] The adjacent ends of the connecting ropes 2 of two adjacent dirt-blocking curtain units are tied and connected. The ends of the load-bearing chains 7 of two adjacent dirt-blocking curtain units are connected by U-shaped fasteners 13. In this embodiment, connecting annular belts 9 are installed and fixed at both ends of the reinforcing belt 8 (adhesive fixation or bolt fixation), and the connecting annular belts 9 are connected to the adjacent connecting chains 12 by U-shaped fasteners 13. The connection methods at the aforementioned positions can improve the integrity of the dirt-blocking curtain facility after construction. At the same time, after the dirt-blocking curtain units are connected in sequence, their respective middle parts are also subjected to lateral pulling, so that the middle part of the dirt-blocking curtain unit can also maintain a pulling and tensioning state, ensuring the stretching effect and improving the interception effect of pollutants.
[0029] In this embodiment, a support steel pipe 11 is also provided in the middle of the dirt-blocking curtain monomer, and the support steel pipe 11 is fixedly connected to the floating body 1 by a binding belt. The purpose of also providing the support steel pipe 11 in the middle of the dirt-blocking curtain monomer is that when the length (also referred to as the span) of the dirt-blocking curtain monomer is large, the middle part is prone to problems such as skewness and stacking, that is, the ability to maintain the posture will be deteriorated. The support steel pipe 11 can provide a certain support function for the middle part of the dirt-blocking curtain monomer, thereby improving the ability of the dirt-blocking curtain facility to maintain the posture.
[0030] It also includes an anchor cable 14 and an anchor 15 arranged on the water-facing side, and the upper end of the anchor cable 14 is fixedly connected to the upper end of the supporting steel pipe 11. The anchor cable 14 and the anchor 15 provide a pulling and anchoring function for the constructed dirt curtain facility on the water-facing side, so that the dirt curtain facility has an enhanced ability to resist water flow and maintain its posture and position.
[0031] Production method of pollution curtain monomer:
[0032] Cloth (such as waterproof canvas, rubber-lined canvas, etc.) is sewn to form a cylindrical outer bag body, a sewing line is set on the upper edge of the outer bag body, a connecting rope 2 is passed through the tubular channel above the sewing line, and a plurality of cylindrical floats are placed in the space below the sewing line, and then the two ends are sewn to form an end sealing edge 3; the bottom edge of the cloth serving as the skirt 5 is turned up and sewn to form a tubular channel, a load-bearing chain 7 is passed through the tubular channel, and the two end edges of the skirt 5 are sewn to form an end sealing edge 3; the bottom edge of the float 1 is fixedly connected to the top edge of the skirt 5 by a reinforcing belt 8, and the end sealing edges 3 at both ends are processed to form end connecting holes 4; connecting annular belts 9 are installed at both ends of the reinforcing belt 8 by bonding, bolting, etc.; and a dirt-blocking curtain monomer is obtained.
[0033] Methods for constructing a closed ring-shaped dirt curtain on site:
[0034] At the construction site, the edges of two adjacent dirt-blocking curtain units are overlapped and a connecting chain 12 is used to pass through the end connecting hole 4 in a zigzag manner, the overlapped end sealing edges 3 are connected as a whole, a supporting steel pipe 11 is passed through the overlapping connection position, and the top of the connecting chain 12 is fixedly connected to the supporting steel pipe 11 with a binding belt, the end of the connecting rope 2 is tied and connected, the connecting annular belt 9 is connected to the nearby connecting chain 12 with a U-shaped fastener 13, and the end of the load-bearing chain 7 is connected with a U-shaped fastener 13; the counterweight 6 is mounted on the bottom load-bearing chain 7 and then dropped into the water body; after being dropped, a small ship is used to appropriately pull the dirt-blocking curtain facility to accurately shift it to the position where dirt blocking is required; then an anchor 15 is thrown on the water side, and the upper end of the anchor cable 14 is fixedly connected to the supporting steel pipe 11.
[0035] According to the different water depths of the sewage blocking area, the pollution curtain facility has two usage forms: in deeper waters, after the pollution curtain facility is deployed, each supporting steel pipe 11 stands upright in the water body, and each counterweight block 6 is suspended in the water body. At this time, the pollution curtain facility is in a completely floating form; in shallower waters, after the pollution curtain facility is deployed, the lower end of each supporting steel pipe 11 is inserted into the bottom mud, and each counterweight block 6 falls on the bottom mud surface (at this time, no counterweight block 6 can be set or a small amount of counterweight block 6 can be set), and at this time, the pollution curtain facility is in a bottom-dragging form.
