Frame structure of aquaponic system assembled by module elements

A frame structure of aquaponic system, comprising:

• a base,
• at least one cultivating tank,
• a cover,
• a first set of vertically-extending connecting members configured to extend from said base for supporting the at least one cultivating tank,
• a second set of vertically-extending connecting members configured to extend from said at least one cultivating tank, or from a second said cultivating tank, for supporting the cover, and
• at least a first, a second, a third, and a fourth horizontally-extending connecting member respectively included in the base and the cover,
• wherein
• said base is a rectangular frame composed of a first one-piece -shaped base member, a second one-piece -shaped base member, and said first and second horizontally-extending connecting members, which transversely connect the first -shaped base member and the second -shaped base member;
• said cover is a rectangular frame composed of a first -shaped frame member, a second -shaped frame member, and said third and fourth horizontally-extending connecting members, which transversely connect the first -shaped frame member and the second -shaped frame member;
• and
• said at least one cultivating tank is provided with connecting lugs for receiving respective first ends or second ends of said first set of vertically-extending connecting members;
• the first end of each of said horizontally-extending and vertically-extending connecting members is formed into a tenon, and the second end of each of said horizontally-extending and vertically-extending connecting members is formed into a mortise;
• the first and second -shaped base members of the base and the first and second -shaped frame members of the cover each includes a linear section and two arms that extend transversely with respect to the linear section to form corners, each of the arms including distal ends extending away from the corners, and each the distal ends being formed into a mortise or a tenon for connecting to one of the tenons or mortises of a respective horizontally-extending connecting member,
• said first and second -shaped base members of the base are each provided with two tenons or two mortises at respective corners, for connecting to corresponding mortises or tenons at the first or second ends of respective said first set of vertically-extending connecting members, and
• said first and second -shaped frame members of the cover are each provided with two tenons or two mortises at respective corners, for connecting to corresponding mortises or tenons at the first or second ends of respective said second set of vertically-extending connecting members.
