Title:
LIQUID LEVEL DETECTION UNIT FOR DRAINAGE EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2022/049881
Kind Code:
A1
Abstract:
A technique is provided which, while suppressing the adhesion of foreign matter to a floating-type water liquid level sensor, increases the degrees of freedom of installation of the liquid level sensor and facilitates floating upwards when tilted. This unit is provided with: a float-type liquid level sensor (20) which is hung from a cable (30) inside of the drainage equipment and which detects when the liquid surface has reached a prescribed liquid level; and a support unit (12A) which extends in the direction of extension of the cable (30) inside of the drainage equipment and which supports the liquid level sensor (20) via the cable (30) so as to allow the liquid level sensor (20) to float upwards. In a state in which the liquid level sensor (20) is supported by the support unit (12A), the direction of extension of the cable (30) crosses the direction of extension of the axis (x1) of the liquid level sensor (20), which extends from the one end (21) where the cable (30) is connected to the other end (22) on the side opposite of the cable (30).
