The invention relates to land reclamation, in particular to the drainage of wetlands with the presence of drainless depressions (a saucepan).

The purpose of the invention is to increase the water intake capacity and increase the reliability of the sump.

The drawing shows the catchment surface water, a General view.

The water collector includes a well body 1, having a lid 2 with filtration openings 3, a drainage pipe 4 with a removable head 5, water receiving windows 6, a float 7 and a counterweight 8, a siphon 9 connected to the drain 10, a tubular air outlet 11 with a check valve 12 , an emphasis 13 and soil filling 14 in the form of peat.

The reservoir works as follows.

In the initial position, there is no water in the well, the float 7 with the counterweight 8 rests on the stop 13, and the top 5 of the catchment pipe 4 is at the level of the lid 2. When a thawed or rain water appears in the dried saucer, it is filtered into the well through the filling 14 and holes 3. The water level in the well rises and forces air out of it into the drain 10 through the air outlet 11 and non-return valve 12. Float 7 with the counterweight 8 and tube 4 fixed to them emerges, with the result that the tip 4 connected to pipe 4 pierces backfilling 14 and vkodit n and the surface of the soil, providing through the intake windows 6 intensive flow of water into the well.

five

When the water level in the well of the upper level of the siphon 9 rises, it triggers and releases water from the well into the drain 10. The lowering of the water level in the well as a result of the siphon 9 on one side and preventing the air from the other side from entering the well 12 in the well, there is a negative pressure, thereby providing a formation between the siphon 9 and the hydraulic communication pipe 4, the driving pipe 4, and also the siphon mode of operation. When draining the saucer and stopping the operation of the pipe 4, the siphon 9 continues to work until the water level in the well drops to the inlet edge of the siphon.

Together with the water level, the float 7 with a counterweight 8 is lowered into the rest position 13, and the pipe 4 is in the well.

Counterweight 8 having a specific

5 weight, equal to the specific gravity of water, when moving the float up, being in the water, does not reduce its lifting force. When moving the same float down it. partially or completely in the air, increases the weight of the water intake device, thereby significantly contributing to its return to its original position.

Claims (2)

1. The catchment of surface water, made in the form of recessed into soil and connected to a drain well, having a vertical retractable catchment pipe and a lid, characterized in that, in order to increase the water intake capacity and increase reliability, the catchment pipe is provided with a removable head and has a float and counterweight attached to its lower part with a specific weight equal to the specific weight of water, while the well communicates with the drain through a siphon and a tubular air outlet with a non-return valve, and a soil filling is made above the well cover. 2. A catchment basin according to claim 1, characterized in that the soil backfilling is made of peat.
