SUBSTANCE: invention relates to a control system having its own buoyancy of the lifting bottom of the pool designed to be installed and moved parallel to the water surface. The control system of the lifting bottom of the pool having its own buoyancy is characterized by the fact that a geared motor is installed in the technical room connected to the angular gearboxes by cardan shafts with the possibility of rotation, whereas the angular gearboxes through the stuffing box units are connected by cardan shafts to the cardan shafts installed at the bottom pool with left and right gearboxes, each of which is equipped with a cable layer, a bypass roller and a cable drum with a wound cable, one end of which is fixed to the cable drum with a wedge, and the other end of the cable through a bypass roller mounted on the gearbox, through the bypass block of the upper bracket a pulley block attached to the lifting bottom, through a bypass block, which is fixed to the lower bracket of the pulley block, fixed to the bottom of the pool, is attached to the upper bracket of the pulley block in the cage using a wedge.

EFFECT: regulation of the lifting bottom of the pool having its own buoyancy without the possibility of hydraulic fluid entering the pool due to the non-use of this fluid due to the use of a gear motor as the main mechanism for driving the transmission in the lifting bottom control system.

Description

The invention relates to a control system for a lifting pool bottom having its own buoyancy, designed for installation and movement parallel to the water surface.

The patent “Swimming pool with adjustable pool floor system”, patent WO 2014069999 A1 is known. From this patent, a hydraulic system is known for tensioning cables for raising and lowering an intermediate lifting bottom of a pool that has its own buoyancy, which consists in the fact that lifting bottom cables are fixed to the bottom of the pool, which pass with the help of pulleys along the bottom of the pool to a hydraulic moving mechanism, using whose lifting bottom can be pulled under the surface of the water and held in the desired position.

This solution has a well-known drawback: in the hydraulic system for tensioning the cables for regulation, it has its own buoyancy The lifting bottom of the pool uses oil, which flows from the hydraulic cylinder along the rod into the pool, is converted into build-up on the mechanisms and forces you to regularly carry out a complex and costly procedure for cleaning from these build-ups. The sealing device proposed in the patent mentioned above does not eliminate the possibility of hydraulic fluid from entering the pool from the cylinder body, but only reduces its likelihood.

The technical result of the invention is to regulate a device that has its own buoyancy lifting the bottom of the pool without the possibility of hydraulic fluid entering the pool due to the non-use of this fluid due to the use of a gear motor as the main mechanism for driving the transmission in the lifting bottom control system.

The technical result is achieved by the fact that a gear motor is installed in the technical room, connected to the angular gearboxes by cardan shafts with the possibility of rotation, while the angular gearboxes are connected through stuffing box units by cardan shafts to the left and right gearboxes installed on the bottom of the pool, each of which has a cable handler installed , a deflection roller and a cable drum with a wound cable, one end of which is fixed to the cable drum using a wedge, and the second end of the cable through a deflection roller mounted on the gearbox, through a deflection block of the upper bracket of the tackle, mounted on a block having its own buoyancy lifting bottom, through a bypass block, which is fixed to the lower bracket of the pulley, fixed to the bottom of the pool, is attached to the upper bracket of the pulley in the cage using a wedge.

The invention is illustrated by drawings, which are shown in:

Implementation of the invention.

Figure 1 shows a general view of the lifting bottom control system in an axonometric view. More specifically, the control system in accordance with the present invention consists of a self-buoyant, located in the pool lifting bottom 1, located in a separate technical room behind the end wall of the pool, a gear motor 2 connected to angular gearboxes 3 by cardan shafts 16 through stuffing box units 6, which are mounted in the end wall of the pool and connected to left gearboxes 4 and right gearboxes installed on the bottom of the pool 5, each of which is equipped with a cable guide 10, a deflection roller 11 and a left cable drum 12 (shown in Figs. 3, 4) or a right cable drum 13 (shown in Figs. 3, 5), respectively, with a wound cable 7, one the end of which is fixed to the cable drum using a wedge 15 (shown in Fig. 3, 4 and 5), and the second end of the cable 7 through the bypass roller 11, through the bypass block 17 (shown in Fig. 7) of the upper bracket of the pulley 9, mounted on lifting bottom 1, through the bypass block 17 (shown in Fig. 6), which is fixed to the lower bracket of the pulley 8, fixed to the bottom of the pool, is attached to the upper bracket of the pulley 9 in the cage 14 using a wedge 15.

Raising or lowering something that has its own buoyancy The lifting bottom 1 is carried out by changing the rotation of the output shaft of the gearmotor 2, while simultaneously winding or winding the cable 6 on all cable drums 12 and 13, which ensures uniformity, respectively, of raising or lowering the lifting bottom 1.

Figure 2 shows the assembly units of the invention located in the technical room (top view). From the gearmotor 2 by cardan shafts 16, rotation is transmitted to the angular gearboxes 3, from the angular gearboxes 3 by cardan shafts 16 through the stuffing box units 6, the torque is transmitted using cardan shafts 16 to the left gearboxes 4 and right gearboxes 5 installed on the bottom of the pool (shown in Fig. . 1). Gland units 6 provide a tight connection between the technical room and the pool.

Figure 3 shows a diagram of the reeving of the cable 6 in the pulley system (rear view). One end of the cable 7 is fixed to the cable drum 12 or 13, depending on the location of the cable drum on the left gearbox 4 or the right gearbox 5, respectively, using a wedge 15, and the second end of the cable 7 through the bypass roller 11, through the bypass block 17 (shown). in Fig.6) of the upper bracket of the pulley 9, fixed to the lifting bottom 1, the bypass block 17 (shown in Fig.5), which is fixed to the lower bracket of the pulley 8, fixed to the bottom of the pool, is mounted on the upper bracket of the pulley 9 in a holder 14 with using a wedge 15.

Figure 4 shows the left version of the gearbox assembly (rear view), namely the left gearbox 4 assembled with a cable handler 10, a deflection roller 11 and a left cable drum 12 installed on it.

Figure 5 shows the right version of the gearbox assembly (rear view), namely the right gearbox 5 assembled with a cable handler 10, a deflection roller 11 and a right cable drum 13 installed on it.

Figure 6 shows the lower bracket of the pulley block 8 (side view) with a bypass block 17 installed on it.

Figure 7 shows the upper bracket of the pulley block 9 (rear view) with a bypass block 17, a holder 14 and a wedge 15 installed on it, as well as with a cable 7 passing through the bypass block 17, the end of which is secured in the holder 14 using a wedge 15.
