[0039] Additionally, the third moving means (15) is installed so as to be located at the bottom of the second moving means (14), and is configured such that a plurality of third moving rollers (15a) provided on the inner surface are in close contact with the outer diameter of the support bar (11a), and a plurality of third connecting bars (15b) provided on the upper surface are connected to the lower edge portion of the second moving means (14), so that the first moving means (13), the second moving means (14), and the third moving means (15) can move in a manner corresponding to the buoyancy plate (12) as the buoyancy plate (12) moves.

[0040] The above configuration is such that the buoyancy plate (12), the first moving means (13), the second moving means (14), and the third moving means (15) are installed on the support bar (11a) of the installation plate (11), and the first moving means (13), the second moving means (14), and the third moving means (15) are configured to move in accordance with the movement of the buoyancy plate (12). Even when the buoyancy plate (12) is installed to surround the upper edge portion of the support bar (11a), the configuration of the first moving means (13), the second moving means (14), and the third moving means (15) prevents the connection between the support bar (11a) and the buoyancy plate (12) from being separated, thereby enabling stable use.

[0041] In addition, through the configuration of the first moving roller (13a), the second moving roller (14a), and the third moving roller (15a) described above, the first moving means (13), the second moving means (14), and the third moving means (15) can achieve stable positional movement according to the positional movement of the buoyancy plate (12).

[0042] And as shown in FIGS. 1 to 3, the above-mentioned installation bar (16) is provided protrudingly on one side of the third moving means (15), and an installation groove (16a) is formed in the inner central portion, and an installation projection (16b) is provided protrudingly on the inner surface adjacent to the third moving means (15), with an elongated installation hole (16b-1) formed in the longitudinal direction, and a pair of elongated guide holes (16c) communicating with the installation groove (16a) are formed facing each other on the upper and lower surfaces.

[0043] This configuration is configured such that when the third moving means (15) moves in correspondence with the movement of the buoyancy plate (12), the installation bar (16) can move in correspondence with the movement of the third moving means (15), and the installation bar (16) is configured such that a foreign substance removal means (20), which will be described in detail below, is detachably coupled thereto.

[0044] Additionally, the foreign substance removal means (20) is detachably coupled to the installation bar (16) so as to be position-adjustable, and a coupling bar (21) coupled to the installation bar (16) is provided at one end, and a contact member (23) is provided at the other end facing the coupling bar (21), and the coupling bar (21) and the contact member (23) are configured in the shape of a long bar connected by a connecting bar (22).

[0045] To explain in detail the configuration of the foreign substance removal means (20), the coupling bar (21) is configured such that a coupling groove (21a) to which the installation projection (16b) is coupled is provided in the inner center portion, and an elongated connecting hole (21b) corresponding to the guide hole (16c) is formed on the upper and lower surfaces. When the coupling bar (21) is coupled to the installation bar (16), the installation projection (16b) is coupled to the coupling groove (21a), and the installation hole (16b-1) of the installation projection (16b) and the guide hole (16c) of the installation bar (16) are configured to form a position corresponding to the connecting hole (21b) of the coupling bar (21).

[0046] This means that when the coupling bar (21) is coupled to the above-mentioned installation bar (16), the above-mentioned installation hole (16b-1), guide hole (16c), and connecting hole (21b) are positioned in corresponding positions, and then the above-mentioned installation hole (16b-1), guide hole (16c), and connecting hole (21b) are configured to be firmly coupled through a bolt (P). In the case where the coupling bar (21) is coupled to the above-mentioned installation groove (16a), it is configured so that the coupling position of the coupling bar (21) coupled to the installation groove (16a) can be adjusted and used.

[0048] In addition, it is preferable that the above-mentioned contact member (23) be formed of an elastic material or configured to form an elastic mesh shape so that it can easily move in response to the movement of the installation bar (16) even when in contact with the purification net (4).

[0049] In addition, through the configuration of the discharge hole (22a) and inlet hole (22b) of the connecting bar (22), when the connecting bar (22) moves in correspondence with the movement of the installation bar (16), the wastewater flowing into the inlet hole (22b) flows into the inside of the discharge hole (22a) and then moves toward the spray hole (23a) of the contact member (23), thereby enabling more convenient removal of various foreign substances provided in the purification net (4).

[0050] Additionally, as shown in FIGS. 1 to 3, a plurality of fastening rings (22c) are further provided along the longitudinal direction of the upper surface of the connecting bar (22), and a support means (30) is further provided on the installation plate (11) to maintain the installation position of the foreign substance removal means (20). The support means (30) comprises a support plate (31) having a plurality of support holes (31a) formed in a portion corresponding to the installation plate (11) to which a bolt (P) is coupled, a guide bar (32) having a pair facing each other on the upper part of the support plate (31), a guide hole (32a) formed in the longitudinal center portion into which the connecting bar (22) is inserted and guided, and a hook (32b) provided on one side of the upper part, and a plurality of connecting strings (33) connecting the fastening rings (22c) and the hook (32b).

[0051] The above configuration is configured such that, through a bolt (P) connected to the support hole (31a) of the support plate (31), the support plate (31) is installed at the bottom of the connecting bar (22), and the connecting bar (22) is inserted into the guide hole (32a) formed in a pair of guide bars (32) provided on the upper part of the support plate (31). This configuration ensures that even when the connecting bar (22) moves up and down, it moves within the guide hole (32a), thereby preventing the installation position of the connecting bar (22) from changing and enabling stable use.

[0052] In addition, the above-mentioned fastening ring (22c) and the hook (32b) are configured to be connected by a plurality of connecting lines (33), thereby preventing the installed position from changing even when the connecting bar (22) moves, and enabling more stable use.

[0053] And as shown in FIGS. 1 to 3, the buoyancy plate (12) has a plurality of installation grooves (12a) formed on both sides and adjacent parts, and at least one auxiliary buoyancy plate (40) is further coupled to the installation grooves (12a), and a bolt hole (11a-1) is further formed on the upper surface of the support bar (11a), and a pressing means (50) for pressing the upper surface of the buoyancy plate (12) is further installed in the bolt hole (11a-1), and the pressing means (50) is composed of a fastening plate (51) having a fastening hole (51a) formed corresponding to the bolt hole (11a-1), a fixing bar (52) extending in the direction of the buoyancy plate (12) from both sides of the fastening plate (51) and having a fixing plate (52a) at the end, and an elastic plate (53) connected to the lower end of the fixing plate (52a) by a plurality of elastic springs (54).

[0054] To explain the above configuration in detail, at least one auxiliary buoyancy plate (40) is connected to the installation groove (12a) of the buoyancy plate (12) according to the user's choice, thereby allowing the buoyancy of the buoyancy plate (12) to be adjusted and used. A bolt (P) connected to the fastening hole (51a) of the fastening plate (51) forming the pressurizing means (50) is connected to the bolt hole (11a-1) of the support bar (11a), and the fastening plate (51) is firmly installed on the upper surface of the support bar (11a). In this state, a pair of fixing bars (52) and elastic plates (53) are installed facing each other with the support bar (11a) as the center, so as to be positioned on the upper surface of the buoyancy plate (12).

[0055] Through this configuration, when the buoyancy plate (12) moves in the downward direction of the collection container (1) as in FIG. 2, the elastic plate (53) and the buoyancy plate (12) are separated, and when the buoyancy plate (12) moves in the upward direction of the collection container (1) as in FIG. 3, the elastic plate (53) is in close contact with the upper surface of the buoyancy plate (12), preventing the separation of the support bar (11a) and the buoyancy plate (12), and the buoyancy plate (12) is configured to be easily moved in the downward direction of the collection container (1) through the elastic force of a plurality of elastic springs (54) provided in the elastic plate (53).

[0056] At this time, the pressurizing means (50) is configured to be used by adjusting the position installed on the support bar (11a) according to the user's choice so as not to hinder the upward and downward movement of the buoyancy plate (12).

[0057] Additionally, as shown in FIGS. 1 to 3, a buoyancy plate moving means (60) connected to the buoyancy plate (12) is further installed on the inner surface of the collection container (1), and the buoyancy plate moving means (60) is composed of a connecting plate (61) that is fixedly installed on the collection container (1) and has a through hole (61a) formed on its upper surface, a guide plate (62) that is fixedly installed on the collection container (1) at the bottom of the connecting plate (61) and has a guide roller (62a) on one side, a fixing ring (63) provided on the outer edge portion of the buoyancy plate (12), and a pull cord (64) that is connected at one end to the fixing ring (63), then guided at the other end by the guide roller (62a) and connected through the through hole (61a), and has a control handle (64a) provided at the other end connected through the through hole (61a).
