Abstract

<P>PROBLEM TO BE SOLVED: To provide a low cost and simple dust-removing device using a highly durable resin net durable for a long period of use, so as to remove the dust which can not be completely removed through a steel screen provided in water-intake (drainage) facilities in a hydraulic power generation water introduction channel or an agriculture drainage channel. <P>SOLUTION: The fixing wire (A) constituting a simple dust-removing installation X is set to the fixing hook (G) of a water channel upper end and a lower stage flat bar (C) is hang down to the lower stage of an existing steel screen, so as to complete the setting. When the highly durable resin net (B) of the simple dust-removing device catches the dust flowing down in the water channel, the hoisting wire (F) arranged at the center of the lower stage flat bar (C) is manually hoisted through a via-eye bolt (E) at the center of the upper end flat bar (D). When the upper end flat bar (D) is overlapped with the lower stage flat bar (C), while shifting from the hoisting wire (F) to the upper and lower stage flat bars (C, D), the resin net is taken out of the water channel for removal of the dust. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention relates to a simple dust removing device for rivers, power generation, and agricultural waterways.

The conventional steel screen has a wide vertical grid interval, and even if a large dust is captured, dust smaller than the vertical grid will pass through. For this reason, small dust can be clogged at the intake port of the pumping machine (pump) at the end of the channel, and it can be broken by abnormal operation. In the case of conventional steel screens, most of them are fixed screens, and the current situation is that the manager removes the dust collected on the screens by rake (rake). In terms of safety, there are also concerns about safety, and the long working hours. A conventional stationary dust remover is a dedicated machine that is produced by a single unit according to the installation location, and requires a large amount of work, so it is very expensive. In addition, maintenance and repair costs after installation increase.

JP2000-1837

It is a lifting-type human-powered dust removal device that is installed on the front surface of an existing steel screen and captures and removes fine dust that has passed through the existing steel screen.

This invention sets the fixing wire (A) of the structure of the simple dust removal equipment X to the fixing hook (G) at the top of the water channel, and hangs the lower flat bar (C) to the lower stage of the existing steel screen, Complete the set. When the dust flowing down from the water channel is captured by the highly durable resin net (B) of the simple dust removal equipment, the lifting wire (F) installed at the center of the lower flat bar (C) is connected to the top flat bar (D). Pull it up manually by way of the center via eyebolt (E). When the top flat bar (D) and the lower flat bar (C) overlap, the lifting wire (F) goes to the upper and lower flat bars (C, D). Change it, take it out of the field, and remove the dust.

Because the product is lightweight, it is easy to install and remove, and there is no need to restrict (or drain) or stop water during installation or removal. Existing steel screens and waterways do not require any processing. Therefore, there is no need for construction related to waterways. There are fewer product parts and less initial investment, no working machine is required, and the running cost is zero. The total cost is only the initial investment, and the effect of cost saving is great. It is almost maintenance-free, but because it uses many commercially available parts, it has excellent durability and reliability, and the parts supply system is in place. Since the amount of dust removal is increased compared to the existing rake work, the on-site work time is shortened and safety is improved.
During product processing, installation, and work, all work is done manually, and CO2 emissions are zero, which is effective for the global environment.

1 is an overall view of the present invention. The operation | movement procedure of this invention.

An embodiment of the present invention is to arrange a net screen on an existing screen and enclose the dust that has flowed out and remove it outside the field. There are various types of nets, such as a diamond shape and a turtle shell shape, but a turtle shell shape with flexible joints is used.

Here, the effects of the simple dust removal equipment are firstly safe and secondly low cost. Third, work efficiency is improved. Therefore, improving the operational effect with respect to the current work efficiency can greatly improve the cost effectiveness.

Set the fixing wire (A) with the structure of the simple dust removal equipment X to the fixing hook (G) at the top of the waterway, and hang the lower flat bar (C) to the lower stage of the existing steel screen to complete the setting. . When the dust flowing down from the water channel is captured by the highly durable resin net (B) of the simple dust removal equipment, the lifting wire (F) installed at the center of the lower flat bar (C) is connected to the top flat bar (D). Pull it up manually by way of the center via eyebolt (E). When the top flat bar (D) and the lower flat bar (C) overlap, the lifting wire (F) goes to the upper and lower flat bars (C, D). Change it, take it out of the field, and remove the dust. See FIG.

Claims (2)

Dust that cannot be removed by steel screens installed at intakes for hydroelectric power generation canals, water supply and sewage treatment plants, and agricultural drainage can be removed or dumped or collected manually using a highly durable resin net. Simple dust removal equipment characterized by doing so. The wire rope is arranged at both ends of the high durability resin net, connected to both ends of the flat rope arranged at the lower end of the net, and the pulling wire rope is arranged at the center part or both ends of the lower end flat rope. Simple dust removal equipment.
