関するものである。Detailed Description of the Invention The present invention provides a surface water intake device for irrigation in which a funnel-shaped water intake plate is provided at the upper end of a retractable water intake pipe, and an abacus-shaped float is provided on the water intake plate via a spacer. At the outer periphery of the upper end of each expandable pipe of the water intake pipe,
By providing an annular air chamber with an appropriate opening at the bottom, the buoyancy of the water intake pipe is increased, and by opening the bottom of the air chamber, damage to the air chamber due to water pressure is eliminated, and the steel plate used is thinner. The present invention relates to a surface water intake device for irrigation with a sub-float that can reduce equipment costs.

た。 A funnel-shaped water intake board is installed at the upper end of the retractable water intake pipe, and an abacus-shaped float is installed on top of the water intake board with a spacer interposed between the water intake board and the float, and surface water from ponds and marshes is used for irrigation. There is a water intake device designed to take in water as water, but since this water intake device uses a heavy steel plate as a material, an abacus-shaped float alone does not have sufficient buoyancy, and for this reason, each of the intake pipes There is a type of sub-float that has a sealed air chamber installed in the expansion tube, but since this air chamber is sealed, it is greatly affected by water pressure, and there is a risk of deformation, especially in the winter. Because of this, thick steel plates must be used for the entire device, which has disadvantages such as high equipment costs.

とが好ましい。 A funnel-shaped water intake board 2 is provided at the upper end of the telescoping water intake pipe 1, and an abacus bead-shaped float 4 is provided on the water intake board 2 via a spacer 3, and the upper end of each telescoping pipe 1' of the water intake pipe 1 is In a surface water intake device for irrigation having an annular air chamber 6 on the outer periphery, an appropriate opening 5 is provided on the bottom surface of the air chamber 6, so that the same pressure as the external water pressure is applied to the inside of the air chamber 6. It was designed so that Preferably, a dust prevention screen 7 is attached to the opening 5.

齎し得た等の大きな利点を齎したものである。 As described above, in providing the air chamber 6 on the outer periphery of the upper end of each telescopic pipe 1' of the water intake pipe 1, the lower surface of the air chamber 6 is opened as appropriate, so that the same pressure as the external water pressure can be applied. By placing the sub-float inside the air chamber 6, the drawbacks of the conventional sub-float described above can be completely eliminated. In other words, since the conventional air chamber as a sub-float is a closed type, it is greatly affected by water pressure, and there is a risk of deformation, especially in the winter. However, in the present invention, it is necessary to use a sub-float, which requires a large amount of equipment cost and has a large weight, which has a negative effect on buoyancy. Since the lower surface of the air chamber 6 is opened appropriately so that the pressure inside and outside the air chamber 6 is the same, there is no influence of water pressure on the inside of the air chamber 6, and therefore it can be used for the entire air chamber related device. By reducing the thickness of the steel plate, it was possible to reduce equipment costs, and the reduction in weight had a positive effect on buoyancy, which brought about great advantages.
