Detailed Description

The invention is further described below in conjunction with the appended drawings and the detailed description.

As shown in fig. 1-3, the invention discloses an underwater lifting platform, which comprises two bearing beams 1, support frames arranged at two ends of the bearing beams 1 and used for supporting the bearing beams 1, a panel 2 fixedly arranged on the upper surface of the bearing beams 1, and a plurality of buoyancy tanks fixedly arranged at the bottom of the bearing beams 1, wherein each buoyancy tank comprises an opening buoyancy tank 3 and a sealing buoyancy tank 4, the bottom of the opening buoyancy tank 3 is provided with an opening, the top of the opening buoyancy tank 3 is connected with an inflation pipeline 5, the inflation pipelines 5 are both communicated with a main air supply pipeline 6, one end of the main air supply pipeline 6 is closed, the other end of the main air supply pipeline is connected with an exhaust valve 7 and an inflation valve 8, compressed air is sealed in the sealing buoyancy tank 4, the inflation valve 8 is communicated with a compressed air source, each support frame comprises a stand column 9 and a rotating shaft 10 rotatably arranged in the stand column 9, The supporting device comprises a plurality of gaps 11 arranged on the upright post 9 and a plurality of supporting plates 12 fixedly arranged on the rotating shaft 10, wherein the supporting plates 12 correspond to the gaps 11 one by one.

The adjusting process comprises the following steps: when lift platform height need be adjusted, only need rotate pivot 10, make in backup pad 12 income stand 9, close evacuation valve 7, open inflation valve 8 and aerify to the opening flotation tank in, because opening flotation tank back-off is in the aquatic, therefore high-pressure gas discharges the water in the opening flotation tank, thereby produce buoyancy, float whole lift platform, and rotate pivot 10, the backup pad 12 with corresponding position is swung out, close inflation valve 8, open evacuation valve 7, discharge the high-pressure gas in the opening flotation tank, lift platform wholly descends to backup pad 12 department, support it by backup pad 12, whole process convenient operation, and noiselessness influences.

In order to avoid the interference phenomenon between the lifting platform and the support plates 12 during the lifting process, the support plates 12 are three, the three support plates 12 are distributed along the length direction of the upright post 9 in a staggered manner, the angle between the support plates 12 is 90 °, for example, when the support plates are arranged at 0 °, the three support plates 12 are simultaneously accommodated in the notch 11, when the support plates are at the 90 ° position, the support plates 12 at the first height position are extended, while the support plates 12 at the other positions are still positioned in the notch 11, when the support plates are at the 180 ° position, the support plates 12 at the second height position are extended, the support plates 12 at the other positions are retracted in the notch 11, when the support plates are at the 270 ° position, the support plates 12 at the third height position are extended, and the support plates 12 at the other positions are retracted in the notch 11.

Thereby whole lift platform has four high gears of use altogether, and the gear does the least, and in all backup pad 12 income breachs 11, lift platform directly supported by the bottom of the pool of swimming pool, three high gear in addition, lift platform supports by the backup pad 12 of relevant position respectively.

In order to realize the smooth movement of the whole lifting platform, the perforated buoyancy tanks 3 and the sealing buoyancy tanks 4 are arranged in a staggered manner, wherein the perforated buoyancy tanks 3 are mainly used for controlling the lifting of the lifting platform, and the buoyancy generated by the sealing buoyancy tanks 4 is used for offsetting the gravity of the bearing beam 1 and the supporting plate 12.

In order to facilitate the operation and realize the one-man operation, be provided with between the support frame and make all pivot 10 synchronous rotation's link gear, link gear is including fixed setting up in one of them runner 13 in the pivot 10, fixed setting up in all eccentric wheel 14 of pivot 10 upper end, connect in adjacent actuating lever 15 between the eccentric wheel 14, the both ends of actuating lever 15 respectively in eccentric wheel 14 rotates mutually and connects, through having set up link gear, when adjusting, only need alone to rotate runner 13 and can realize the synchronous rotation of all pivots 10 to realize packing up and stretching out of backup pad 12, it is convenient to adjust, need not many people to operate, has improved efficiency greatly.

The optimization scheme adopted in the embodiment is that the compressed air source is an air compressor, and in addition, a fan and the like can be used for filling compressed air into the opening buoyancy tank.
