Description

Technical Field

[0001] The present application relates to the technical field of water channel biological interception, and in particular to a net bag replacement device and method that can reduce diving operations. Background Art

[0002] The interception net is a device used to intercept or capture target aquatic organisms in specific waters. The purpose of setting up underwater organism interception nets in water intake channels is to effectively block floating objects and harmful organisms, protect water quality, maintain ecological balance, and prevent the loss of important aquatic organisms.

[0003] The currently used interception net bag installation methods include fixed installation, floating installation and modular assembly. Fixed installation is to fix the interception net bag at a specific position of the water inlet channel, such as the entrance or a place where the water flow is slow. The fixing point can be selected from the canal wall, pile foundation or other stable structure, and the net bag is firmly fixed with ropes, chains and other materials. This method is suitable for scenes with relatively stable water flow and is easy to manage and maintain. Floating installation is to use floating devices such as buoys or buoys to enable the interception net bag to float freely with changes in water surface height. Floating interception net bags can better adapt to waters with large water level fluctuations, ensuring continuous and effective interception of floating objects and organisms. Modular assembly can use multiple standardized modules for splicing and installation, and each module is an independent interception unit.

[0004] However, both fixed installation and modular assembly require personnel to dive to fix the bottom of the interception net when replacing the interception net. Although floating installation does not require personnel to dive when replacing the interception net, the gap between the floating interception net and the canal wall and pile foundation is usually too large, resulting in poor interception effect. Summary of the invention

[0005] In order to achieve a better interception effect while reducing the number of diving operations when replacing an interception net bag, the present application provides a net bag replacement device and method that can reduce diving operations.

[0006] On the one hand, the present application provides a net bag replacement device that can reduce diving operations, using the following technical solutions: A net bag replacement device capable of reducing diving operations, comprising: The net deployment support comprises an underwater anchor beam and a support pile arranged on the underwater anchor beam, wherein two support piles are arranged on the underwater anchor beam at intervals, an above-water pedestal is arranged at one end of the support pile away from the underwater anchor beam, and a side ring and a middle ring are fixed on the underwater anchor beam; A net bag is arranged between the two support piles, and a floating member is connected to the top of the net bag; The traction mechanism comprises a first driving member, a second driving member, a back-and-forth rope and a middle pull rope, and each of the above-water platforms is rotatably provided with a guide wheel; the back-and-forth rope is wound around the outside of the guide wheel, and the side rings are arranged one-to-one with the back-and-forth ropes; both ends of the back-and-forth rope are connected to the first driving member, and the side rings are sleeved on the outside of the corresponding back-and-forth ropes, and the first driving member is used to drive the back-and-forth rope to move; one end of the middle pull rope is connected to the second driving member, and the other end is connected to the net bag after passing through the middle ring, and the second driving member is used to drive the middle pull rope to move; A guide rope, each of the above-water platforms is connected with a guide rope, one end of the guide rope is connected to the underwater anchor beam; The connecting assembly includes a top corner connecting piece arranged at the top corner of the net bag, a bottom corner connecting piece arranged at the bottom corner of the net bag, and side connecting pieces arranged on both sides of the net bag; the top corner connecting piece is detachably connected to the supporting pile, and the bottom corner connecting piece is detachably connected to one end of the reciprocating rope close to the side ring; the side connecting piece is sleeved on the adjacent guide rope and is slidably connected to the guide rope.

The net bag is lowered, the first driving member and the second driving member are started, the bottom corner connector is driven by the pull rope to move to the side ring, and the middle pull rope is loosened, so that the middle pull rope is lowered to the underwater anchor beam with the movement of the bottom corner connector. The installation of the net bag on the net display bracket can be realized. At this time, a pair of side edges of the net bag are tensioned under the action of the guide rope and the side connector, and the other pair of side edges are tensioned under the action of the middle pull rope and the floating member. The gap between the side edge of the net bag and the supporting pile is small, and the gap between the bottom edge of the net bag and the underwater anchor beam is also small, which has a consumption interception effect.

When the part of the net bag close to the top is hit by a ship, the net bag can slide downward to allow the ship to pass, and then reset under the action of the floating member, so it is not easy to be damaged.

[0013] Optionally, a tension bracket is fixed on the above-water platform, the tension bracket includes a fixed frame and a suspension rod structure, the suspension rod structure includes a first suspension rod, a second suspension rod and an adjustment bracket, and the first suspension rod and the second suspension rod are both provided with threaded sections; One end of the first suspension rod is connected to the fixed frame, and the other end is passed through the adjustment bracket and is threadedly connected to the adjustment bracket; One end of the second suspension rod is connected to the guide rope, and the other end is passed through the adjustment bracket and is threadedly connected to the adjustment bracket; The rotating adjustment bracket can drive the first suspension rod and the second suspension rod to move relative to each other.

[0014] By adopting the above technical solution, the first boom and the second boom are respectively connected to the fixed frame and the guide rope, and the first boom and the second boom are allowed to move relative to each other by adjusting the rotation of the bracket, thereby realizing the tightness adjustment of the guide rope; the tension of the guide rope can be conveniently adjusted on the water, thereby ensuring that the net bag is always in the best interception state.

[0015] Optionally, the side connecting piece is configured as a sliding shackle.

[0016] By adopting the above technical solution, the side connector is set as a sliding shackle, making the connection between the two sides of the net bag more flexible and able to slide smoothly on the guide rope, thereby avoiding deformation or damage of the net bag due to the jamming of the connector during the deployment and recovery of the net bag, and improving the efficiency and safety of net bag replacement. At the same time, the design of the sliding shackle also facilitates the disassembly and assembly of the net bag, reduces the difficulty of operation during replacement, and further reduces the frequency of diving operations.

[0017] Optionally, two connecting ends are arranged at intervals on the rope section of one end of the guide rope close to the above-water platform, and a disconnecting component is arranged between the two connecting ends, and the disconnecting component is used to connect or disconnect the two connecting ends.

[0018] By adopting the above technical solution, two connection ends are arranged at intervals on the rope section of the end of the guide rope close to the water support platform, and a disconnection component is provided, so that the guide rope can be quickly disconnected and reconnected when needed. It is convenient to directly disconnect the two connection ends when replacing the net bag, and directly put the side connection piece on the guide rope along the connection end, which significantly improves the flexibility and convenience of the net bag replacement process.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] Example 1 Reference Figure 1 and Figure 2The net bag replacement device that can reduce diving operations provided in the embodiment of the present application includes a net display bracket 1, a net bag 2, a traction mechanism 3, a guide rope 4 and a connecting assembly 5. Among them, the net display bracket 1 includes an underwater anchor beam 11, a support pile 13 arranged on the underwater anchor beam 11, and an above-water platform 14 fixed to the top of the support pile 13. Two support piles 13 are arranged at intervals on the underwater anchor beam 11, and two above-water platforms 14 are also arranged corresponding to the above-water platforms 14. Two side rings 15 are arranged correspondingly below each above-water platform 14, and the side rings 15 are fixedly connected to the underwater anchor beam 11; a plurality of middle rings 16 are also arranged between the two side rings 15, and the middle rings 16 are fixedly connected to the underwater anchor beam 11. In this embodiment, two middle rings 16 are arranged at intervals. The support piles 13 are made of reinforced concrete to ensure their stability underwater.

[0032] Reference Figure 2 and Figure 3 , each of the above-water platforms 14 is fixed with a tension bracket 6, the tension bracket 6 includes a fixed frame 61, and a suspension rod structure 62, the suspension rod structure 62 includes a first suspension rod 621, a second suspension rod 622 and an adjustment bracket 623, the first suspension rod 621 and the second suspension rod 622 are both provided with a threaded section, and the rotation direction of the first suspension rod 621 and the second suspension rod outer thread section is opposite. One end of the first suspension rod 621 is connected to the fixed frame 61, and the other end is passed through the adjustment bracket 623 and threadedly connected to the adjustment bracket 623. One end of each second suspension rod 622 is connected to a guide rope 4, and the other end is passed through the adjustment bracket 623 and threadedly connected to the adjustment bracket 623. After one end of the guide rope 4 passes through the above-water platform 14, it is fixed to the underwater anchor beam 11. The guide rope 4 specifically adopts a high-strength steel wire rope to ensure its strength and durability underwater, and the diameter range of the guide rope 4 is 28-25mm. In this embodiment, 20mm is specifically selected.

[0033] By rotating the adjustment bracket 623, the first suspension rod 621 and the second suspension rod 622 can be driven to move relative to each other, thereby adjusting the tension of the guide rope 4. In other embodiments, the tension of the guide rope 4 can also be adjusted by a hand chain hoist.

[0034] Reference Figure 3 The net bag 2 is arranged between two supporting piles 13, and a plurality of floating members 21 are connected to the top of the net bag 2 at intervals. The floating member 21 can be a floating ball or an air bag to ensure that the top of the net bag 2 is always near the water surface.

[0035] Reference Figure 2 and Figure 3The connection assembly 5 includes top corner connectors fixedly connected to the two top corners of the net bag 2, bottom corner connectors fixed to the two bottom corners of the net bag 2, and side connectors fixed to both sides of the net bag 2. The top corner connector is specifically configured as a first shackle 51, and a first connecting ring 12 is provided at one end of the support pile 13 close to the water support platform 14, and the first shackle 51 is sleeved on the first connecting ring 12. A detachable connection between the net bag 2 and the support pile 13 is achieved. The side connector can adopt a sliding shackle 54 to facilitate quick disassembly and assembly.

[0036] Reference Figure 1 The traction mechanism 3 includes a first driving member 31, a second driving member 32, a reciprocating rope 33 and a middle pull rope 34. Each water support platform 14 is rotatably connected to a guide wheel 35 through a bracket. In this embodiment, two guide wheels 35 are provided corresponding to the first driving member 31 and the reciprocating rope 33, and two guide wheels 35 are provided corresponding to the second driving member 32 and the middle pull rope 34.

[0037] The back-and-forth rope 33 is wound around the corresponding guide wheel 35, and the back-and-forth rope 33 is set in a ring shape. The first driving member 31 is installed on the rope segment of the back-and-forth rope 33; after one end of the middle pull rope 34 is connected to the second driving member 32, the other end passes through the middle ring 16 and is then tied to the bottom of the net bag 2. The first driving member 31 and the second driving member 32 both use energy storage winches. Starting the first driving member 31 can drive the back-and-forth rope 33 to move, and starting the second driving member 32 can drive the middle pull rope 34 to move.

[0038] Reference Figure 2 The bottom corner connector adopts a second shackle 53, and a second connecting ring 331 is fixed to one end of the round-trip rope 33 close to the side ring 15. The second shackle 53 is sleeved on the second connecting ring 331 to realize the detachable connection between the net bag 2 and the round-trip rope 33. The size of the second shackle 53 is smaller than the inner diameter of the second connecting ring 331, so that the second shackle 53 cannot pass through the second connecting ring 331. The sliding shackle 54 is sleeved on the adjacent guide rope 4 and is slidably connected to the guide rope 4. On the one hand, the sliding shackle 54 ensures that the two sides of the net bag 2 can slide smoothly along the guide rope 4 during the movement; on the other hand, it allows the side of the net bag 2 to be unfolded, reducing the gap between the side of the net bag 2 and the support pile 13, and achieving a better interception effect.

[0039] The specific implementation principle of this embodiment 1 is as follows: first, fix the underwater anchor beam 11 to the bottom of the canal, and then insert the support pile 13 into the embedded hole of the underwater anchor beam 11 to ensure its verticality. Then fix the water support platform 14 to the top of the support pile 13 to ensure its stability on the water surface. Finally, fix the side ring 15 and the middle ring 16 on the underwater anchor beam 11 to ensure that their positions are accurate. Then hoist the net bag 2 between the two water support platforms 14, and then evenly distribute the floating parts 21 on the top of the net bag 2 to ensure that the top of the net bag 2 is near the water surface. Then fix the top angle connector on the support pile 13, the bottom angle connector on the back and forth rope 33, and the side connector on the guide rope 4 to ensure that the net bag 2 can slide smoothly during movement. Install the first drive member 31 and the second drive member 32 on the water support platform 14 to ensure that they are connected to the power supply normally. Then connect one end of the return rope 33 to the first driving member 31, and the other end is connected to the first driving member 31 after passing through the side ring 15. Then connect one end of the middle pull rope 34 to the second driving member 32, and the other end is connected to the bottom of the net bag 2 after passing through the middle ring 16. Connect one end of the guide rope 4 to the above-water platform 14, and fix the other end to the underwater anchor beam 11 through an anchor block. Tighten the guide rope 4 through the boom structure 62 to ensure that its tension is moderate. When the net bag 2 needs to be replaced, just start the first driving member 31 and the second driving member 32, and lift and remove the old net bag 2 by driving the return rope 33 and the middle pull rope 34. Then hoist the new net bag 2 to the specified position, and reconnect the top corner connector, bottom corner connector and side connector.

[0040] Example 2 Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the top angle connector is replaced by a connecting slider 52, a vertical slide 17 is provided at one end of the support pile 13 close to the water platform 14, and the connecting slider 52 is slidably connected to the vertical slide 17.

[0041] Reference Figure 5, two connecting ends 41 are arranged at intervals on the rope section of one end of the guide rope 4 close to the water support platform 14, and a disconnection component 42 is arranged between the two connecting ends 41. The disconnection component 42 includes a first screw 421, a second screw 422 and a connecting tube 423, the first screw 421 is fixedly connected to one connecting end 41, and the second screw 422 is fixedly connected to the other connecting end 41. One end of the first screw 421 is passed through and threadedly connected to the connecting tube 423, and one end of the second screw 422 is passed through and threadedly connected to the connecting tube 423. The connecting tube 423 is provided with threads inside, which match the threaded sections of the first screw 421 and the second screw 422. The connecting tube 423 is provided with a magnetic suction sleeve 424, which is made of strong magnetic material and can absorb the first screw 421 to ensure that it will not loosen in the disconnected state. In other embodiments, the magnetic suction sleeve 424 can also be an electromagnet.

[0042] By rotating the connecting tube 423, the first screw rod 421 is separated from the connecting tube 423, and the two connecting ends 41 can be disconnected. The magnetic suction sleeve 424 is sleeved on the outside of the connecting tube 423 to ensure that it can absorb the first screw rod 421, so that after the first screw rod 421 is disconnected from the connecting tube 423, it can be placed close to the connecting tube 423 under the action of the magnetic suction sleeve 424, and the rope section of the guide rope 4 located underwater is difficult to fall over.

[0043] The setting of the disconnecting assembly 42 enables the guide rope 4 to be quickly disconnected and reconnected when needed. When replacing the net bag 2, the two connecting ends 41 can be directly disconnected, and the side connecting piece can be directly sleeved onto the guide rope 4 along the connecting ends 41, which significantly improves the flexibility and convenience of the net bag 2 replacement process.
