In particular, floating dust drifting to the seaweed, fish, and pearl farms will cause a great deal of damage to the farm, so it is necessary to remove the floating dust flowing from the upstream of the river before reaching the farm.

In the past, ropes were installed from both banks of the river upstream of structures such as weirs, and suspended dust collected on the net was collected by ships. It has to travel back and forth many times, and it is difficult and time consuming to move suspended dust collected on the ship to the shore. Also, working on a ship is unstable and dangerous.
Several devices have been proposed for automatically collecting these airborne dust.

  In the garbage collection device disclosed in the above-mentioned Patent Document 1, wastes connected to the river are obliquely passed to both banks of the river, and the garbage is collected in the garbage collection pond. Because it is vacant, it is difficult for garbage to flow down from the bottom of the float and increase the efficiency of collecting garbage.

  The river garbage collection device disclosed in Patent Document 2 installs garbage transporting means with endless belts with protrusions in the middle of the river, so the structure becomes large and it is difficult to remove temporarily during heavy rains, etc. There's a problem.

  In the floating substance collection apparatus for rivers disclosed in Patent Document 3, floating substances are gathered in one outflow floating substance treatment facility by a mesh field stretched diagonally across the water surface of the river. Since the suspended matter caught in the water cannot be collected naturally, there is a problem that it is necessary to periodically remove the suspended matter.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a river floating dust automatic recovery device that has high dust collection efficiency, can be easily installed and removed, and can easily remove floating dust.

In order to solve the above-described problems, an automatic apparatus for collecting airborne dust according to the present invention includes an upstream drive mechanism and a downstream drive mechanism respectively installed on one river bank on the upstream side and the other river bank on the downstream side. An endless net body driven by the system is installed in an oblique direction with respect to the river flow, and a floating dust collection site is installed in the vicinity of the downstream drive mechanism to collect the floating dust induced by the net body. It is characterized by.
In the present invention, the nets are installed obliquely with respect to the river flow by the driving mechanisms installed on both river banks, and the nets are moved from the upstream side to move the nets to the downstream driving mechanism side. The dust is received by the mesh body, and separated and collected by the floating dust collection site provided on the downstream drive mechanism side. By continuously performing this process, floating dust in the river can be efficiently recovered and removed. The suspended dust collected in the suspended dust collection site is lifted up by a machine such as a bucket conveyor or manually, and is subjected to predetermined processing.

It is also possible to provide a flow rate sensor that detects the flow rate of the river, and to provide a network drive speed control mechanism that changes the drive speed of the network according to the flow rate detected by the flow rate sensor. Thereby, when the flow velocity of the river is high, the driving speed of the network body can be increased, the resistance to the river flow can be reduced, and the efficient driving of the network body can be performed.
A water level sensor for detecting the water level of the river is provided on the upstream river bank and the downstream river bank, and the upstream drive mechanism and the downstream drive mechanism are moved up and down in accordance with the water level detected by the water level sensor. A height control mechanism for controlling the height to be substantially constant with respect to the water level can also be provided.

As shown in FIG. 1, the river floating dust automatic recovery apparatus according to the embodiment of the present invention includes an upstream drive mechanism 10 and a downstream drive mechanism on one river bank on the upstream side and the other river bank on the downstream side, respectively. 20, an endless network 30 that is driven endlessly by the upstream drive mechanism 10 and the downstream drive mechanism 20 is installed in an oblique direction with respect to the flow of the river. In the vicinity of the downstream drive mechanism 20, a floating dust collection place 40 for collecting floating dust guided by the mesh body 30 is installed. In this embodiment, when this device is installed near the mouth of the river, the flow of the river may flow backward due to the flow of tides. A second floating dust collection place 50 that is received and collected by the mesh body 30 is provided in the vicinity of the upstream drive mechanism 10.

  The floating dust collection sites 40 and 50 scoop the riverbank, partition the riverbank earth and sand with concrete walls 41 and 51 or sheet piles, and end the net 30 driven by the downstream drive mechanism 20 and the upstream drive mechanism 10. I accept it. The suspended dust transferred by the mesh body 30 is separated from the mesh body 30 in the suspended dust collection sites 40 and 50 and stored there. Wire meshes 42 and 52 are provided on the downstream side of the floating dust collection sites 40 and 50 so that only water flows and the floating dust does not flow downstream.

  An example of the downstream drive mechanism 20 is shown in FIG. The downstream drive mechanism 20 can be rotated by a bearing 25 between a base 21 made of concrete, a machine frame 22 indicated by a support 23 on the base 21, and between the base 21 and the machine frame 22. A rotary drive shaft 24 installed and a drive motor 26 for rotating the rotary drive shaft 24 are provided.

  On the other hand, as the mesh body 30, a high-strength chemical fiber net (vinyl, vinylon, polyethylene, etc.) is used, and the upper and lower wires 31 and 32 support the upper and lower sides of the mesh body 30 in the vertical direction. The reinforcing wire 33 holds the width of the mesh body 30 in the height direction. A float 34 is attached in the vicinity of the center of the net 30 along the horizontal direction.

  As shown in FIG. 3, the rotary drive shaft 24 has a key groove 24 a formed in the vertical direction around the rotary drive shaft 24, and the elevating drive shaft 27 having a key 27 a fitted in the key groove 24 a on the inner periphery is formed on the rotary drive shaft 24. It is mated. A bearing 27b is fitted in the key 27a in the vertical direction, and friction between the key 27a and the key groove 24a is reduced so that the ascending and descending can be performed smoothly. An upper wire pulley 27c and a lower wire pulley 27d are formed at the upper and lower portions of the elevating drive shaft 27 so that the upper wire 31 and the lower wire 32 of the mesh body 30 can be passed therethrough, respectively. A buoyancy adjustment float 28 is provided at the bottom of the lift drive shaft 27. Thereby, the water level W.V. L. Following up and down (see FIG. 1B), the elevating drive shaft 27 moves up and down, and accordingly, the net 30 stretched between the upper wire 31 and the lower wire 32 also moves up and down.

  The upstream drive mechanism 10 has the same configuration, and the network 30 stretched between the upstream drive mechanism 10 and the downstream drive mechanism 20 has a float 34 whose water level W. L. Accordingly, the net body 30 can always capture the suspended dust floating and flowing near the water surface of the river at the optimum position.

  In the present embodiment configured as described above, when the net body 30 is conveyed obliquely to the downstream side of the river by rotating the drive motor 26 of the downstream side drive mechanism 20, the suspended dust captured by the net body 30 is It is separated from the mesh body 30 in the floating dust collection place 40 where the downstream drive mechanism 20 is installed. Since the water freely flows downstream by the wire mesh 42, only the floating dust is stored in the floating dust collection place 40. The stored airborne dust can be landed from the shore side, and since it is a work on a stable ground even by manual work, labor is remarkably reduced as compared with work on a ship. In addition, the work can be automated by using a bucket conveyor or the like. In addition, as a power source of the drive motor 26, in addition to normal commercial power, a solar power generation device in which a solar panel and a storage battery are combined can be used or used together.

  River level W. L. Changes, the lifting drive shaft 27 moves up and down along the rotational drive shaft 24 by the buoyancy of the buoyancy adjusting float 28, and the net body 30 also moves up and down by the buoyancy of the float 34, so that floating dust is always captured at an appropriate position. be able to.

  When the flow velocity of the river increases, the pressure applied to the mesh body 30 increases, and when the suspended dust is caught on the mesh body 30, the mesh body 30 becomes more resistant, but by increasing the moving speed of the mesh body 30, Resistance applied to the net 30 can be reduced.

  In this case, a flow rate sensor (not shown) that detects the flow rate of the river is provided, and a network drive speed control mechanism (not shown) that changes the drive speed of the network 30 according to the flow rate detected by the flow rate sensor. By providing, the speed control of the mesh body 30 can be realized. As described above, when the flow velocity of the river is high, the driving speed of the mesh body 30 is increased, the resistance to the flow of the river is reduced, and the efficient driving of the mesh body 30 can be performed.

  In the above-described embodiment, the elevating drive shaft 27 is provided with the buoyancy adjustment float 28 so that the water level W.V. L. In this configuration, a mechanism is provided that automatically adjusts the height to the fluctuation of the water level. However, a water level sensor is provided separately, and according to the output of the water level sensor, it is moved up and down by a drive mechanism provided with a separate lifting drive shaft 27. You can also.

  Further, a floating dust detachment mechanism (not shown) that detaches the floating dust attached to the mesh body 30 with the pressure of water or air can be provided in the vicinity of the downstream drive mechanism 20. Thereby, the suspended dust adhering to the net body 30 can be forcibly separated and collected in the suspended dust collection site.

  Furthermore, in an emergency such as a river flooded by a typhoon or heavy rain, the mesh body 30 is wound around one of the upstream drive mechanism 10 or the downstream drive mechanism 20 or a mechanism for lifting the mesh body 30 so as not to be immersed in the river. A mechanism for retracting can also be provided.
