CANAL RETENTION DEVICE, DRAINAGE SYSTEM AND CORRESPONDING METHOD Russian patent published in 2024 - IPC E03F3/04 

FIELD: drainage devices.

SUBSTANCE: channel retaining device (200) comprises retaining seat (102), which has first interface area (102k) and retaining area (102a) for retaining drain channel extending along one direction, retaining base (104), which has second interface area (104k). First interface region (102k) and second interface region (104k) are configured to interface with each other to form hinge joint (106), which provides retaining seat (102) and retaining base (104) with one rotational degree (111) of freedom relative to each other, which extends substantially along said direction. Device also comprises locking device (108), which is configured to be transferred to a first state for locking rotational degree (111) of freedom, so that retaining socket (102) and retaining base (104) are fixed relative to each other, and with possibility of its transfer into second state for releasing rotational degree of freedom (111), so that retaining seat (102) and retaining base (104) are movable relative to each other. Retaining base (104) comprises a lever mechanism which is pivotally movable when locking device (108) is in a second state, and is fixed when locking device (108) is in first state. Drainage system (100) comprises the above described device (200) for retention of the channel, drainage channel (1704), which extends longitudinally along said direction (101) and is retained by retention socket (102) of device (200) for retention of channel. Method of mounting drain channel (1704) using above described device (200) for holding channel consists in aligning drain channel (1704), which extends longitudinally along said direction and is retained by means of retaining socket (102) of device (200) for retaining channel, wherein alignment includes movement of retaining socket (102) relative to retaining base (104) in accordance with rotational degree (111) of freedom, transfer of locking device (108) from second state to first state so that retaining socket (102) and retaining base (104) are fixed relative to each other. Channel retaining device (200) comprises retaining seat (102), which has clamping device (304a, 304b, 304) and holding area (102a) for holding drain channel passing along one direction. Clamping device has a recess to accommodate at least one support post that extends from the holding area. Clamping device is made with possibility, when installed in the first state, clamping at least one support post so that retaining seat (102) and at least one support post are fixed relative to each other, and with possibility, when installed in second state, providing at least one support post of one rotational degree of freedom (111), which passes along said direction, so that retaining seat (102) and support post are pivotally connected to each other.

EFFECT: providing an economical and less complex relief leveling mechanism, which clearly provides the most accurate height and/or position alignment with minimum efforts, and also improves the overall quality of the drainage system.
