SU32389A1 - Shutter device for driftwood with driftwood - Google Patents

Description

The invention relates to a closure device for water bodies with floating timber, for example, located in the tidal zone of the sorting channels, forest exchange basins, etc., made in the form of a narrow, proper length, raft, one end connected through a flexible link fixed subject.

In the proposed stopper device, the raft is provided from below, in its middle part, submerged in water with a shield from branches, planks, etc. in order to achieve an automatic turn of the shutter, by the action of water (for example, tidal or ebb) that occurs in an undesirable direction. to the position that closes the wood passage, in order to prevent the wood from being hijacked by this flow, as well as to open the passage, when the flow changes in the desired direction.

In FIG. 1 shows a top view of the shutter device; FIG. 2 is the same side view and FIG. A 3-4-bolt device installed in the channel for wood-alloy materials is fenced off.

The proposed shutter device is a raft 7 narrow in two to four logs. Knocked down by the method of sbivka

sprouting (vrazbezhku) to a length exceeding the width of the closed channel by 2-6 meters (depending on the installation location).

When assembling in the middle of the raft (between the pairs of logs), a narrow aperture is left that passes through the entire length of the raft; Into this hole, spruce spruces are passed down to their apices to a depth of approximately one meter, and the butt ends of the boughs are fixed in the channel by clamping them to the logs with a bar or a perch nailed into two or three nails. Spruce paws are arranged in a channel in the thickness of several rows so as to constitute a rather dense barrier to meet the water. This shield 2 you arrange}. When the raft 7 is already shot down and is set in place. Shield 2 is designed so that the raft perceives the force of the current and moves in its direction, overcoming the force of wind and other obstacles acting on it on the surface of the water.

To eliminate a snug fit of the raft 7, the lugs 3 attached to the raft 7 are designed in the positions that open the passage.

The stop 5 has a length depending on the length of the raft itself, the place of its attachment and on what place it is

will abut; it is only necessary that he hold the raft at an angle of approximately 15-20 °. |

A thin, short rope or wire may be used to hold the stop; it is only necessary that its hook be made either almost at the water level or on a relatively high bank so that the rope or wire, in the first case, is submerged in water, and in the second it hangs above the water and does not prevent the passage of the Timber Raft. The fifth raft is attached by a chain at the point where two bark are mounted, keeping the boom at a certain distance from the coast.

Subject invented.

1, Breeder with driftwood materials, for example, located in the zone

tides of sorting channels, pool, forest exchanges, etc. made in the form of a narrow, proper length.-raft, one end connected through a flexible connection to a fixed object, characterized in that for automatic rotation of the shutter, unwanted flow direction. water (for example, tidal or ebb tide), to the position that closes the wood passage, as well as to open the passage, when the flow changes in the desired direction, the raft / is equipped with the bottom, and its middle part, longitudinal, immersed in water, shield 2 branches, boards, etc.

2. When the device is a. 1 the use of stops 3 fixed to the raft in order to prevent the raft from snugly fitting in the opening passage position to the wall of the water reservoir.
