Fig. 3 is the assembly drawing of quadra and gauze brush.(5) are rectangular brushes among the figure, and (6) are quadras, and both are screwed.

Embodiment

The plank that will be drilled with circular hole among Fig. 1 is made quadra (6) with triangle iron plate by screw by the Square Net-cage peripheral size, again with screw with itself and rectangular brush (5) (see figure 3) that tightens together, form parts---square box posture wave brush.Be connected with frame-type sinker (10) below by connection cord (9), constitute a device.

Shown in Fig. 2-1 and Fig. 2-2 this device is put into Square Net-cage, will tighten rope (7) and pass circular hole on the quadra (6), upper end and etting (3) upper edge is fixed on the net cage upper frame (1) jointly.Be fixed on jointly on the net cage underframe (sinker) (4) with etting (3) lower edge below, the length of tightening rope (7) is highly identical with etting (3), etting (3) with tighten the gravity effect that rope (7) is subjected to net cage bottom framework (sinker) (4) jointly, always to keep tensioned state.This state can make that brush body is easier presses close to etting (3).Because the peripheral size of square box posture wave brush is basic identical with the net cage peripheral size, and square box posture wave brush is the inboard that is contained in net cage, also can play the close of brush body and etting (3) and act on.Can suitably strengthen the weight of Square Net-cage bottom framework (sinker) (4) in case of necessity.

In Fig. 2-1, the position on sea when A represents high tide, B represents the seawater position on sea at ebb tide, C represents the position in seabed.The upper-lower position of the relative seabed C of Square Net-cage is by the sea decision, and the upper-lower position in relative seabed, sea is determined by the tide is flowing and ebbing.

During Fig. 2-2 expression high tide, square box posture wave is brushed under the action of gravity of frame-type sinker (10), moves downward the bottom of Square Net-cage.Fig. 2-1 expression when seawater at ebb tide, frame-type sinker (10) falls into the seabed, square box posture wave brush is not subjected to the influence of frame-type sinker (10) gravity, upwards runs to the top of Square Net-cage by self buoyancy, by rising only liter of location-plate (8) with onlying.The moving up and down of the relative etting of this brush body (3) can reach the scrubbing action to etting (3).

General tidal range of culturing the sea area is all more than 5 meters, and the net cage height is generally 3-5 rice, and tidal range can satisfy the stroke requirement of square box posture wave brush.Tidewater rises and move back twice every day, basically can satisfy the motion frequency of square box posture wave brush, and wave can improve frequency and the speed that net cage moves up and down greatly, when wave forms on the sea on net cage top, net cage can rise to certain height by wave with the float on the net cage, moment is fallen back to original position again then, and this makes the motion of the relative etting of brush body (3) that impulsive force more be arranged.

The expression state of connection cord (9) at ebb tide and at the incoming tide respectively in Fig. 2-1 and Fig. 2-2, the length of connection cord (9) can be according to the depth and the net cage height setting of culturing the sea area, ought can make frame-type sinker (10) break away from the seabed in principle at the incoming tide, with square box posture wave swishing sound to the bottom of net cage, square box posture wave is brushed be raised to the net cage top, be frame-type sinker (10) (the frame-type sinker can be made with the bending of iron and steel rod) below the connection cord (9), the actual weight of frame-type sinker (10) in seawater should be decided according to the buoyancy that net cage float (2) and quadra (6) are produced.

The buoyancy that quadra (6) is produced can calculate by following computational methods:

With present normally used specification is that 3 meters * 3 meters Square Net-cage is example (below be converted into decimetre):

Adopt common 0.8 decimeter thick, 1.2 decimeters wide kahikatea plank is done quadra

Then the area of section of plank is: S=0.8 * 1.2=0.96 decimetre ²

Then the total length of plank is: $L=30\×4+30\sqrt{2}=162.4$ Decimetre (

: the cornerwise length of sufficient as shown in Figure 1 quadra)

Then the cumulative volume of quadra is: 55.9 decimeters of V=S * L=0.96 * 162.4=1 ³

The proportion of seawater is at least d=1

Then the quadra buoyancy that can produce at least in seawater is: F floats=155.9 * 1=155.9 kilogram

The proportion of kahikatea is d=0.41

Then the own wt of the wooden quadra of kahikatea is: G=155.9 * 0.41=63.9 kilogram

Consideration kahikatea wood frame is soaked proportion for a long time and can be increased to some extent in water, select 1.2 to be enhancement coefficient

Then the weight of the wooden quadra of kahikatea is: G=155.9 * 0.41 * 1.2=76.7 kilogram

Then the net buoyancy that produced of the wooden quadra of kahikatea is: F is floating=155.9-76.7=79.2 kilogram only

Square box posture wave is brushed the average buoyancy that every linear meter produces: flat floating=79.2/ (3 * 4)=6.6 of F kilogram/meter, the frictional force that is used to overcome between brush body and the etting (3) is upwards moved.

The weight of frame-type sinker (10) should be decided according to the ability to bear of above-mentioned result of calculation and net cage float.Frame-type sinker (10) the net weight power that can produce in seawater is greater than net buoyancy that the kahikatea wood frame produced more than 1 times in principle, so that when high tide, can produce enough pulling force, overcome square box posture wave brush buoyancy upwards, it is pulled to the bottom of Square Net-cage, the pulling force that frame-type sinker (10) produces is big more, and gauze brush is big more to the dynamics of scrubbing of etting (3).But consider the ability to bear of net cage float and the bulk strength of net cage.

Section as Fig. 3 rectangular brush of the present utility model (5) bottom parts adopted "

" the shape structure.When this structure can effectively prevent rectangular brush (5) with etting (3) friction the stress of brush body root is concentrated, prolonged the service life of brush body.Small sircle hole in the front view is represented the position of brush body root, and the two row brush bodies layout that staggers can more effectively focus on frictional force on the etting (3) on arranging.
