Description

Anti-shark and life-saving protective net for seashore bathing field

The utility model is relevant with the safety of bathing beach, more detailed it, refer to anti-shark in a kind of bathing beach and lifesaving grille guard especially.

At present bathing beach safety measure, nothing more than some caution poster and the lifesaving personnel of a little, other lifesaving appliances are seldom arranged, and general visitor is when playing with water, often ignored the warning of warning poster, the lifesaving personnel of minority also are difficult to the safety problem with respect to most visitors, treat that visitor's offshore to abyssal zone place plays,, so do not understand water-based and do not know the waters situation again in case of flood tide or ebb and can't get back to the bank immediately and cause danger even drown, the visitor is drowned incident often takes place, moreover all kinds of biological species are various in the ocean, and have the biological many of aggressiveness, as shark etc., the visitor swims in the bathing beach, but can't know what seabed situation, when has the fish of brutality, biological occur and visitor's life security constituted a threat to being difficult to give material, if any accident, the lifesaving personnel more can't bring into play the lifesaving function.Have the mirror what this, the main purpose of the utility model, tying up to provides anti-shark in a kind of bathing beach and lifesaving grille guard, it can provide the safety that increases the bathing beach and prevent that shark from attacking the visitor.

The utility model is by a main support, the elevating oil cylinder device, grille guard, major part such as spud pile and ball float constitutes, its feature is at what: this main support what sea is set as a protective range, and what avris and bottom are provided with grille guard, this avris grille guard and cooperate several ball floats to rise with the work seawater moving back rises and falls props up, so that form a protection safety scope, appropriate location in the main support bottom then is provided with some elevating oil cylinder devices, this cylinder body partly is to bury place, what seabed, one side is set as spud pile in the coastline and in addition, then be provided with movable roller in conjunction with the main support place, to cooperate the elevating oil cylinder device when rising, main support can produce an action that makes progress and pull back, and main support promptly pins down by movable roller and spud pile generation, makes the unlikely disengaging spud pile of main support;

Combinations thereof, the utility model not only can prevent the action radius that violent marine life such as shark are invaded bathing beaches, but and what visitor when drowned, rapidly grille guard is risen by the elevating oil cylinder device, to guarantee the safety of personnel's life.

Now after lifting a preferred embodiment and cooperating graphic explanation what:

Fig. 1 is the block diagram of the utility model one preferred embodiment.

Fig. 2 A, Fig. 2 B are the elevating oil cylinder device scheme drawing of the utility model one preferred embodiment.

Fig. 3 is the movable roller structure scheme drawing of the utility model one preferred embodiment.

Fig. 4 is the support shaft access node structure scheme drawing of the utility model one preferred embodiment.

Fig. 5 is the fixing scheme drawing of monitoring device of the utility model one preferred embodiment.

See also Fig. 1, Fig. 2 A, Fig. 2 B and shown in Figure 3, the utility model is anti-shark in a kind of bathing beach and lifesaving grille guard, wherein comprise a main support (10), at least one elevating oil cylinder device (20), one grille guard (30), monitoring device (50) in the water of one spud pile (40) and plural number, this main support (10) what sea is set as the support body of an about U type scope, wherein two side stands (11) are looked the seabeach and are extended the degree of dip be and establish it to the sea, then the cylinder body (21) with the oil hydraulic cylinder device (20) of lifting combines another support (12) in the lower end, the cylinder body (21) of other this elevating oil cylinder device (20), system is interconnected by an oil pressure pipe (22), this oil pressure pipe (22) is connected with mutually with on the bank oil pressure pump, can be by unified implementation on the bank when the operation lifting; The protective range that this main support (10) is is provided with nylon grille guard (31), this nylon grille guard (31) is the buoyancy by ball float (311), and rise and fall and prop up to form a guard plot along with rising of seawater moves back, other is in the bottom of this main support (10) guard plot, then be provided with the closeer spacer screen (32) of the bigger net seam of structure, this grille guard (30) is played with water in can making visitor's what net, but when causing danger more what main support (10) and elevating oil cylinder device (20) do vertical motion, and mat spacer screen (32) is raised up to the visitor on the sea by marine; In addition, be provided with several spud piles (40) in coastal waters water front one side, this spud pile (40) is pile body (41) to be implanted in the sand ground fix it, the upper end body of rod (42) then bassets, and be provided with movable roller (421) in the body of rod (42) one sides, this movable roller (421) also cooperates the roller groove (111) that is set as on the support (11) and moves, when this structure is cylinder body (21) the do rising of elevating oil cylinder device (20), main support (10) is boosted can be an action that makes progress and pull back, this activity roller (421) is for cooperating this motion structure, and pin down rolling in the what roller groove (111), make main support (10) can do upward movement smoothly and unlikely disengaging spud pile (40) and damaging; (as shown in Figure 4) this main support (10) but in addition what support (11) (12) one ends be set as external screw thread (13) and the other end is set as the bigger flaring portion (14) of external diameter, and what flaring portion internal diameter is provided with negative thread (141).So that can strengthen the protective range of main support (10) in the bathing beach in big marine site, but the mode that is coupling of this tool screw thread when more what does not use dismounting storE.

In addition, all variant in the seashore region that the seawater bath place of each department is, and extra large visitor can not understand its water-based one by one, the depth to the what seabed also can't predict, the lifesaving personnel more can't play a role by actv. in vast marine site, so but other what main support (10) of this case is gone up monitoring device (50) in the installing water, monitoring device (50) is to be located at lug (15) (as shown in Figure 5) on the what main support (10), fixing by bolt (51) and nut (52), make this monitoring device (50) can look the activity situation in visitor's what marine site, but so then interior activity of actv. supervision visitor's what grille guard (30) of lifeguard, playing with water that the visitor more can be relieved practiced riding the waves.

Moreover, when drowning as the prominent visitor of chance, but lifeguard's what rises elevating oil cylinder device (20) operation on the bank, when cylinder body (21) rises, promote support (12) end and do vertical motion, when support (12) by cylinder body (21) when raising, the support of both sides (11) i.e. is action thereupon, is a fixed sturcture by what main support (10) with elevating oil cylinder device (20), support (11) is a vertical motion that pulls back when rising, at this moment, movable roller (421) on the spud pile (40) promptly moves, the interior rolling of movable roller (421) what roller groove (111) is also pining down support (11), when making main support (10), and break away from pining down of spud pile (40) not because of vertical motion.

In sum, anti-shark in a kind of bathing beach of the utility model and lifesaving grille guard, it cooperates the technological thought of innovation with special spatial shape, improve the safety of bathing beach, prevent the attack of violent biology in the ocean, have the effect of progress, meet the condition of utility model patent.
