The invention relates to a power conditioner device. This invention enhances the maintenance when the individual electronic component fails and realizes low cost maintenance. When raising the DC power supplied from a solar cell or a fuel cell by means of a DC / DC converter circuit (30) and converting to the AC power by means of an inverter circuit (40), an electronic circuit such as the DC / DC converter circuit (30) and the inverter circuit (40) or a CPU for controlling the operation of the circuits are accommodated in a case body to supply the AC power to a general load, the DC / DC converter circuit (30) and the inverter circuit (40) are mounted on a DC / DC converter circuit mounting substrate (31) and an inverter circuit mounting substrate (41), which are configured as separate bodies, for modularization.

A mask device, comprising: a mask main body, covering the user's nose and mouth; a plurality of air cleaners, connected to both sides of the mask main body, sucking in external air and filtering impurities, and supplying the filtered air to the mask main body; And a plurality of ear-hanging parts, a plurality of air cleaners are combined on one side and fixed to the ears on both sides of the user; at least one ear-hanging part includes: a first main body, configured between the mask main body and at least one air cleaner, at least An air cleaner is supported on the first body; the second body extends from one side of the first body to the user's ear, and is in contact with at least one air cleaner; the third body extends from the other side of the first body The user's ear extends and contacts the at least one air cleaner; and the fourth body connects the second body and the third body and contacts the user's ear.

The invention discloses a property management and maintenance method. The method comprises the following steps: firstly, acquiring basic information and information of to-be-maintained equipment which are filled by maintenance personnel and correspond to the maintenance personnel; selecting an initial target maintenance personnel corresponding to the information of to-be-maintained equipment according to the map information and the basic information; judging whether the initial target maintenance personnel pass the audit or not; if yes, taking the initial target maintenance personnel as final target maintenance personnel, and feeding back information of to-be-maintained equipment to enable the final target maintenance personnel to reach a place of the to-be-maintained equipment for maintenance, the information of to-be-maintained equipment including place of the to-be-maintained equipment; and if not, selecting another initial target maintenance personnel corresponding to the information of to-be-maintained equipment according to the map information and the basic information, and returning to the step of judging whether the initial target maintenance personnel pass the audit. According to the method, the initial target maintenance personnel can be determined according to the information of to-be-maintained equipment and the basic information of the maintenance personnel, and then the final target maintenance personnel are determined, so that the maintenance work of the place of the to-be-maintained equipment is relatively high and the maintenance efficiency is relatively high.

The present invention has been devised to solve the problem mentioned above and a purpose thereof is to provide a solar panel support having a buoyant body, which has excellent buoyancy retention, enables easy maintenance, and even during maintenance, can maintain maximum supportability. A solar panel support according to one aspect of the present invention comprises a buoyant body for supportinga solar panel, wherein the buoyant body comprises: a parent buoyant body including a coupling hole formed therethrough; and a child buoyant body detachably and fittedly inserted to the coupling hole.
