As shown in Figure 2, porting 8 is connected with aerating and exhaust device (aerating and exhaust device not shown in accompanying drawing) by flexible pipe 9, is provided with control valve 10 on flexible pipe.
As shown in accompanying drawing 2 and accompanying drawing 3, heavy stone 11 is connected respectively at the two ends of hollow tube, wherein the heavy stone weight of porting one end is more than the heavy stone weight into discharge outlet one end, in the present embodiment, the heavy stone weight of porting one end is 2 times of the heavy stone weight into discharge outlet one end, porting end with enter discharge ends and sink acting in follow-up description of stone weight differential and will mention.
As shown in accompanying drawing 2 and accompanying drawing 3, multiple cursory balls 3 are fastened on hack lever 6 by drift rope 12.
2, accompanying drawing 4 and accompanying drawing 5 describe the lifting process of this lift shellfish algae culture raft frame below in conjunction with the accompanying drawings.
As shown in Figure 4, when culture raft frame is positioned on sea level, the inner chamber of hack lever 6 is full of air, control valve 10 shown in accompanying drawing 2 is closed, and enters discharge outlet 8 and is blocked by sea water, is formed and seal space in the inner chamber of hack lever 6, the buoyancy relying on hack lever 6 self to produce makes whole raft frame swim on sea level, now, cursory ball 3 and drift rope 12 swim on sea level, and the buoyancy that cursory ball 3 produces or not impact to whole raft frame.As can be seen here, when designing heavy stone weight, the gross weight controlling heavy stone 11 should be less than buoyancy produced by water after hack lever 6 air inlet, to ensure that whole raft frame can swim on sea level.
As shown in accompanying drawing 3 and accompanying drawing 4, cause for preventing hack lever 6 from twisting under the influence of stormy waves surface into discharge outlet 8 thus cause hack lever 6 inner chamber closure failure, sea water exchanges with the air in hack lever inner chamber, air in hack lever escapes and sea water can enter in hack lever inner chamber by entering discharge outlet 8, in the present embodiment, enter discharge outlet 8 and be provided with a vertical tube 13, vertical tube 13 is through with the inner chamber of hack lever 6, during design, between the length of vertical tube 13 controls as 30-60cm, guarantee that hack lever 6 is when twisting, vertical tube 13 lower ending opening is always positioned under sea level utilizing sea water that the inner chamber of hack lever 6 is formed closure.
As shown in accompanying drawing 4 and accompanying drawing 5, when whole raft frame is down under sea level by needs, open the control valve 10 on flexible pipe 9, hack lever 6 under the pulling of heavy stone 11 sea water by the inner chamber entering discharge outlet 8 and entering into hack lever 6, and the air in hack lever 6 is discharged by the porting 7 on hack lever 6 under the promotion entering sea water, along with the weight gradually increasing whole hack lever 6 of the internal sea water of hack lever 6 increases, hack lever 6 gradually moves under sea level, after hack lever 6 is flooded by sea water completely, air in hack lever is drained, closing control valve 10, hack lever 6 continues to move downward, after drift rope 12 is straightened completely, whole raft frame is fixed transfixion on underwater fixed position by the buoyancy relying on cursory ball 3.As can be seen here, as long as the length adjusting drift rope 12 can control the degree of depth of whole raft frame landing, this is used for adjusting water depth in shellfish algae growth stage and brings great convenience, for convenience of observing the raft frame degree of depth in water layer, on drift rope 12, length scale can be set, during adjustment, only according to the degree of depth of landing, drift rope need to be adjusted to regulation scale.The adjustment of drift rope 12 length can use the mode of setting fastening, specifies position to tie up on hack lever 6 in drift rope.When typhoon, it is possible to using said method to drop under sea level by whole raft frame, the feature utilizing stormy waves under the water surface little avoids raft frame destroyed by the invasion and attack of typhoon.The number of certain cursory ball 3 should ensure that its gross buoyancy gross weight more than heavy stone, in the present embodiment, every hack lever 6 is arranged on 3 cursory balls, its two ends being disposed on hack lever and centre position.
When needing the raft frame under by the water surface to rise on the water surface, first open aerating and exhaust device, then control valve 10 is opened, gases at high pressure are rushed in hack lever 6 inner chamber by porting 7 by aerating and exhaust device, and the sea water in hack lever 6 is discharged, after rushing in a certain amount of gas by entering discharge outlet 8 under the promotion of gases at high pressure, after buoyancy produced by hack lever 6 is more than heavy stone weight, hack lever 6 i.e. moves to direction, sea level, when hack lever 6 rises on sea level completely, and closing control valve 10 and aerating and exhaust device.When designing this hack lever, by porting 7 and enter discharge outlet 8 and be separately positioned on the two ends of hack lever and can solve the problem that in prior art after being charged into gases at high pressure, gases at high pressure form disturbance to the sea water in inner chamber, and gas is directly discharged by entering discharge outlet 8.Owing to hack lever 6 possesses certain length, after being at one end charged into gas, this air-flow can only form disturbance to the sea water in this end-rack bar inner chamber and promote the sea water in inner chamber to move to entering discharge outlet direction, thus reaches the purpose discharged by sea water in hack lever inner chamber.If porting 7 and the spacing entered between discharge outlet 8 arrange less, air-flow can be caused to pass water body and directly to escape by entering discharge outlet 8, it is impossible to ensure that the sea water in inner chamber is fully drained.
When making this lift raft frame, arranging of heavy stone 11 has strong influence to steadily lifting of whole raft frame.As shown in accompanying drawing 4 and accompanying drawing 5, when controlling hack lever 6 and declining, hack lever 6 initially enters sea water with the one end entering discharge outlet 8, when sea water is gradually increasing after in the hack lever inner chamber of this end, first this end of hack lever moves under water, and now hack lever is formed and tilts to decline, for preventing this phenomenon from occurring, the balance at hack lever two ends is reached, it is ensured that hack lever 6 steadily enters and drops under water by the heavy stone weight increasing hack lever 6 porting 7 one end.And when raft frame rises, first hack lever 6 is charged into air with one end of porting 7, when air is gradually increasing after in the hack lever inner chamber of this end, this end of hack lever is first to Waterborne movable, now hack lever is formed and ramps up, and the balance at hack lever two ends is reached by the heavy stone weight increasing porting 7 one end, can ensure that hack lever 6 steadily rises equally.Hack lever 6 two ends sink the weight proportion of stone 11 and can carry out reasonable computation, in the present embodiment, hack lever diameter 10cm according to the length of hack lever and diameter, and length 50m, the heavy stone weight ratio at hack lever two ends controls substantially can ensure the steady lifting of hack lever for 1:2.
