Abstract

PURPOSE:To recover floating dust on water surface with good efficiency by providing a water surface flow generator by which to allow water surface flow to flow into an inlet with a screen connected to its front face for a floating base on water surface. CONSTITUTION:Two inlets 3a and 3b for water surface flow are provided in one lower side of a base 1a with floats 2a and 2b, and dust-collecting screens 4a and 4b are provided to the front faces of the inlets 3a and 3b. Guide pipes 5a and 5b leading to the inlets 3a and 3b are erectly set toward the downside of the center of the base 1a, and propellers 6a and 6b connected to prime movers 8a and 8b are set in the pipes 5a and 5b to make up a floating type dust collector. The dust collector is floated on the surface of water in a dam, etc., and the propellers 6a and 6b are turned to generate water flow, whereupon floating dust is collected on the front face of the screens 4a and 4b and recovered into a hopper 30 by elevating a rake 12.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floating dust collector that collects dust, etc. floating on the water surface of a dam etc. and facilitates the removal and recovery of the dust. be.

(Prior art) In the case of water intake at a dam, etc., floating dust (especially wood) on the water surface is extremely harmful to various facilities installed in the dam (gates, pulp, power generation water turbines, etc.), so the following Dust is collected and removed by means such as

(i) As shown in Figure 5, a dust collection screen (α) is installed in front of the water intake, and the dust collection screen (α) catches and collects floating debris, etc. A fixed device that removes and collects the collected dust in front of the dust collection screen (α) using a rake (C) that is placed in front of the dust collection screen (α) and is operated up and down by the dust remover body (h) above the water intake. Type dust collection device.

(11) A catamaran (d) as shown in Figure 6 is self-propelled, and floating debris is taken in from the front (e) side, and the dust collection section (
1) A self-propelled type (i
ii) As shown in Figure 7, a dustproof net is installed on the upstream side of the dam, and the dustproof net catches and collects the debris that flows into the dam. Inflow prevention device to prevent this from happening.

4V) Dust removal work in which crew members aboard a boat or work vessel bring floating debris onto the ship.

Measures such as these are used.゛ (Problems with the prior art) In the fixed dust collection device (i) above, when water is taken in, the water flow causes floating dust to pass through the dust collection screen (α
) and prevent it from flowing into various equipment, but if water is not being taken in, the dust is not actively collected, and the dust collected on the dust collection screen may drift away due to wind, etc. Dust collection and dust removal efficiency is low.

In addition, since the self-propelled work boat mentioned in (II) above is self-propelled within a limited area such as the mountainous area of a dam, it is a small boat and the dust collection tank has a small capacity, making it difficult to collect. In addition, the dust collection efficiency for floating dust scattered on the water surface is low.

Although the inflow prevention device 011) can prevent inflow into various equipment such as gates, the dustproof net is large and requires a lot of effort to remove and collect the collected material in front of the net.

Furthermore, the above-mentioned dust removal operation requires a lot of effort and time, which poses a problem in terms of labor saving.

All of the above-mentioned means have many problems in terms of dust collection, dust removal, or recovery, and require labor saving.

(Objective of the Invention, Means for Solving Problems) The present invention was developed in view of the above-mentioned circumstances, and includes a floating body floating on the water surface and a floating body disposed around the floating body. an even number of surface flow inlets, a dust collection screen provided at each of the inflow ports, and a dust collection screen provided on the floating body that is connected to the inflow ports and causes the surface flow to flow into the inflow ports. The structure is characterized by having an even number of surface flow generation devices, and a surface flow inlet with a dust collection screen on a floating body floating on the water surface, and a surface flow generation device that causes the surface flow to flow into the inlet. By providing an even number of sets of
The object of the present invention is to provide a floating type dust collector which facilitates collection and eliminates the above-mentioned drawbacks of the conventional dust collector.

(Embodiment of the Invention) Fig. 1 and Fig. 2 show a first embodiment of the present invention.

(Effects of the Invention) As described above, in the present invention, a floating body is floated to a desired position on the water surface, a water surface flow is generated by an even number of water surface flow generation devices, and a water surface flow is generated from a wide area around the floating body in an even number. Since the water can flow into the inlet of the floating body, it is possible to maintain the floating body almost at a predetermined position without applying any special propulsive force, and at the same time, a surface flow is generated from a wide area around the floating body. The water surface flow flows into the inlet, and the dust collection screen provided at the inlet allows floating dust and the like to be collected extremely efficiently, and the dust collection performance is significantly improved.

In addition, since dust can be collected from above the water surface over a wide range, it can be carried out continuously over a long period of time, and therefore dust removal and collection work from the dust collection screen can be performed easily and efficiently, resulting in significant labor savings. It has the effect of being able to do things.
