On 11, the decline of pull bar main body 3 is limited；Prevent the sealing plate 4 of 3 lower end of pull bar main body from contacting with ground, also prevent connection
Plate 5 and 11 impact several times of fixed sleeving, cause that connecting plate 5 is ruptured with pull bar main body 3 or fixed support 2 ftractures.
Spacing hole can be interior threaded hole, and locating part 6 can be screw rod, and it is interior with regard to rising that such screw rod is screwed onto spacing hole
To spacing function；Or locating part 6 is the bolt with nut, bolt is installed top nut after spacing hole and can also play limit
The effect of position.
As shown in Figure 4, Figure 5, further, 1 lower end of drain body is provided with supporting table 14, and supporting table 14 surrounds discharge outlet
13 are provided with one week.
In the present embodiment, one week supporting table 14 is provided with the outside of the discharge outlet 13 of 1 lower end of drain body, so in pull bar
When main body 3 drives sealing plate 4 to move up and down, sealing plate 4 is contacted with supporting table 14, not with 1 directly contact of drain body.
On above-described embodiment basis, further, 1 lower end of drain body is provided with fixing device, fixed dress
It is set to multiple, uniform ring is provided with one week around supporting table 14.
On above-described embodiment basis, further, 14 overcoat of supporting table is provided with sealing ring 15, fixing device
Sealing ring 15 is fixed in supporting table 14.
Sealing ring 15 is enclosed within outside supporting table 14, sealing ring 15 is fixed on outside supporting table 14 by fixing device, so close
Shrouding 4 is contacted with supporting table 14, and sealing ring 15 can play a part of sealing, when filling water, is reduced in drainage arrangement
Water is flowed out between sealing plate 4 and supporting table 14 so as to which drainage arrangement drainage effect is more preferable.
The lower end of sealing ring 15 can less than supporting table 14 lower end, such sealing plate 4 contact with supporting table 14 when
Wait, can sealing ring 15 be carried out extruding makes the effect of its sealing more preferable.
On above-described embodiment basis, further, fixing device includes fixing platform 16 and is arranged on fixed
Fixture 17 on platform 16, is provided with screwed hole in fixed platform 16, and fixture 17 is threaded in fixed platform 16.
In the present embodiment, fixed platform 16 is arc, is threaded hole, fixture 17 in the fixed platform 16 of arc
For bolt, bolt passes through screwed hole, end count seal 15 to be fixed in fixed platform 16, is achieved in that sealing discharge outlet 13, prevents
Water is flowed out from the discharge outlet 13 of drain body 1.
With reference to Fig. 6, Fig. 7, further, sealing plate 4 is provided with towards 1 side of drain body and is matched with supporting table 14
Annular fixed station 18,15 lower end of sealing ring are relative with annular 18 top of fixed station.
In the present embodiment, annular fixed station 18 is provided with sealing plate 4, and the cavity volume that annular fixed station 18 is formed can hold
Receive supporting table 14, the sealing ring 15 outside supporting table 14 is relative with annular fixed station 18, and annular fixed station 18 being capable of crush seal
Circle 15, can so play better seal effect.
At the construction field (site), using the supporting crane of job site, connecting plate is connected by lifting rope, drainage arrangement is put into
In steel bushing, when drainage arrangement is entered in steel bushing, loosen the lifting rope on crane, drainage arrangement can be in the gravity of itself
In the presence of, slowly sink under the water, while the sealing plate 4 of 1 lower end of drain body is opened in the presence of spring 8, water energy it is enough from
Discharge outlet 13 and enter drain body 1 into swelling.
When water inlet 12 of the water level in steel bushing less than drainage arrangement top, the water in steel bushing can also be from draining
Bottom of device discharge outlet 13 enters drainage arrangement.
When water fills thickness in drain body 1, lift drainage arrangement using crane, pull bar main body 3 is in the presence of crane, close
Discharge outlet 13 can be blocked by shrouding 4, thus can walk the water transport in drain body 1；When drainage arrangement is hung out steel bushing by crane
Pipe, is turned back to and sluices out, after drainage arrangement is steady on the ground, loosens lifting rope, by the effect of the pressure and spring 8 of water,
Sealing plate 4 is made to depart from discharge outlet 13, water is released from discharge outlet 13；Repeat the above steps are capable of achieving Quick drainage.
With reference to Fig. 1, Fig. 2 and Fig. 3, further, 1 lower end of drain body is provided with the support for supporting drain body 1
Lower limb 7.
In the present embodiment, 1 lower end of drain body arranges three supporting legs 7, and three supporting legs 7 are uniformly arranged drain body
Below 1, there is a certain distance on 4 lower end of sealing plate and ground, so ensure drain body 1 when draining, sealing plate 4 with arrange
The mouth of a river 13 can space out, and so facilitate the discharge of water；Prevent sealing plate 4 with discharge outlet 13 apart from too short, 13 row of discharge outlet
Water is not smooth.
Ribs is provided with sealing plate 4, can so strengthen the intensity of sealing plate 4, while can also increase sealing
The gravity of plate 4；When draining, sealing plate 4 can be detached rapider with discharge outlet 13, and drainage effect is more preferable.
The drainage arrangement that this utility model is provided, using the supporting crane in job site by chain cylinder lever connecting rod device
Connecting plate 5, connecting plate 5 drives pull bar main body 3 to move upwards, and the diameter with diameter greater than discharge outlet 13 of sealing plate 4 is so close
Shrouding 4 will not be entered in drain body 1 from discharge outlet 13；Pull bar main body 3 is fixed by fixed sleeving 11, so ensure that pull bar
The movement of device above-below direction；Run-off the straight when drain body 1 is moved is prevented, drainage effect is reduced；
Whole drainage arrangement is put in steel bushing using crane, with overhead crane control lifting rope, drainage arrangement relies on itself
Action of gravity slowly sink under the water, sealing plate 4 and discharge outlet 13 keep a quota space under the action of the spring, water energy it is enough from
Water inlet 12 and discharge outlet 13 are entered in drain body 1, and after drain body 1 fills water, crane pulls pull rod device, pull bar
Sealing plate 4 on device blocks discharge outlet 13, and holds up drain body 1 and move upwards.
Drainage arrangement is removed from steel bushing；When drainage arrangement moves to offtake, after drainage arrangement is steadily placed, with
Pull rod device does not have the pulling force of lifting rope, the gravity of itself downwards, sealing plate 4 away from discharge outlet 13 at, water is flowed out from discharge outlet 13；
So repeatedly, the quick discharge to the water in steel bushing is realized, solves normally the water in steel bushing, shadow cannot be discharged using water pump
Ring the problem of construction speed and construction quality.
Finally it should be noted that：Various embodiments above is only illustrating the technical solution of the utility model, rather than which is limited
System；Although being described in detail to this utility model with reference to foregoing embodiments, one of ordinary skill in the art should
