The device 1 also includes a passage 7 in which a second shaft 8 is located. The passage 7 is mounted through the first wall 31 to pass through this wall 31 from its inner face 310 to the outer face 311 of this first wall 31. The inner face 310 and the outer face 311 are opposite each other according to the transverse horizontal direction Y. The second shaft 8 has a first end 81 attached to the first movement transmission mechanism 6. Accordingly, the first end 81 of the second tree 8 is located on the side of the inner face 310 of the first wall 31. The second tree 8 also comprises a second end 82 connected by a second transmission mechanism 9 to a motor 10 of drive located on the side of the outer face 311 of the first wall 31. The second end 82 of the second shaft 8 is located on the side of the outer face 311 of the first wall 31. The drive motor 10 is capable of causing the rotation of the first shaft 5 of the drum 2 from the engine 10 by means of successively the second transmission mechanism 9, the second shaft 8 and the first transmission mechanism 6.

The drive motor 10 is, for example, a motor that has a third rotating shaft 101, which is driven in rotation when the engine 10 is started or in a first direction of rotation that causes, by means of the mechanism 9, the tree 8 and of mechanism 6, the rotation of the first tree 5 in a direction of unwinding of the cover around the drum 2, or in a second direction of rotation, inverse to the first direction of rotation and which causes, by means of mechanism 9, of the shaft 8 and of the mechanism 6, the rotation of the shaft 5 in a direction of winding the cover around the drum 2. For this purpose, the motor 10 comprises control means 102 for starting the engine 10 in the first direction of rotation or in the second direction of rotation or for stopping the rotation of the motor 10. These control means 102 are connected to a user interface 103, external to the motor 10 (located above the level of the drill 11) and suitable to be operated by r a user to control the engine running in one direction or another or the engine stop. Of course, several rotation speeds of the motor 10 can be provided in one direction and / or another. The motor 10 can be, for example, an electric motor.

The angle change 905 comprises a first conical pin 904 fixed to the rotating shaft 903 and a second conical pin 906 fixed to the second end 82 of the second tree 8, the first axis 903 extending in a direction not parallel to the second tree 8 and, for example , perpendicular (for example, parallel to the Z direction) to the second tree 8 (extending, for example, parallel to the Y direction). The second conical pin 906 meshes with the first conic pin 904. Likewise, the third shaft 101 of the motor 10 extends in a direction not parallel to the second shaft 8 and, for example, perpendicular (extending, for example, parallel to the Z direction ) to the second shaft 8. The number of teeth of the sprockets 901 and 902 as well as conical pins 904 and 905 is such that the rotation of the third shaft 101 of the engine 10 causes the rotation of the second shaft 8 at a different speed from the of this shaft 101. Of course, in the box 10, the conical pins 904 and 906 and the angle change 905 can be replaced by a different orientation of the motor 10 so that the shaft 903 is parallel to the tree 8.

The second tree 8, the mechanisms 6 and 9 and the mounting means 4 are arranged such that the second tree 8 is at a determined first height H1 above the first tree 5.

Thus, the invention makes it possible to raise the level N of the water E in the pool in which the winding drum 2 is submerged, even to the first height H1, that is, to the level of the second tree 8 and the second passing piece 7 , and even above, as shown by way of example in Figure 1. The water level N is no longer limited and, therefore, may be higher than the level of the second tree 8.

Thus, the pool can be filled with water E until it has a level N located at the bottom 110 of the drill 11 of this pool.

Thus, according to one embodiment, the passage part 7 is arranged to be crowned by the pool 11, as shown in Figures 1, 4, 5, 6, and 7 as an example.

The drill 7 includes, for example, a flange 111 that exceeds the first wall 31 on the side of the inner face 310, that is, above the first end 81 of the shaft 8 and in the transverse direction Y.

According to the invention, the motor 10 is in a box 12 located at a second height determined H2 above the first tree 5.

According to one embodiment, the box 12 comprises in its upper part 120 a cover 121 which allows access to the engine 10 at the top when this cover 121 is open. Cap 121 can be found flush with the tank.

The first wheel 61 is fixed to the shaft 14, while the second wheel 62 is fixed to the first end 81 of the second shaft 8. The rotation of the second wheel 62 caused by the rotation of the second shaft 8 causes, by means of the belt 63 of union, the rotation of the first wheel 61, thus driving in rotation the shaft 14 and then the shaft 5 of the drum 2. Pulleys 61, 62 connected by a transmission belt 63 can be provided instead of the sprockets 61, 62 and the belt 63. Of course, any other first movement transmission mechanism 6 could be provided between the second tree 8 and the tree 14 and / or the first tree 5.

In the embodiment shown in Figures 1, 6 and 7, the first plate 41 extends to the passage piece 7 and / or to the upper edge 312 of the first wall 31. For example, the first plate 41 is fixed to a third upper plate 44 which in turn serves to fix the upper edge 312 of the wall 31. The upper plate 44 is located, for example, on the part 7.

In the embodiment of Figures 6 and 7, the plate 41 comprises one or more upper legs 43 for fixing to a corresponding part 440 of the third upper plate 44. The upper fixing leg or legs 43 are formed, for example, by one or several parts 43 angled or folded at 90 °, located protruding from the wall 31 (i.e. extending in a transverse direction Y that moves away from the wall 31 towards the inside of the pool and above the water E of the pool), for example horizontally, and connected to the main part 410 of the wall 41 intended to be mounted against the wall 31 and, for example, vertically. The corresponding part 440 of the third upper plate 44 is located projecting with respect to the wall 31 (i.e. the part 440 extends in a transverse direction Y that moves away from the wall 31 towards the inside of the pool and above the water E of the pool). This or these legs 43 are fixed to the third upper plate 44, for example under this plate 44, and this by a fixing means that can be a bolting or others.

The first plate 41 comprises, for example, a recess 45 which can be, for example, a hole 45 or a recess 45 for the passage of the first end 81 of the second tree 8 through this recess 45. The drill 11 is arranged in this case in the third plate 44 and in the wall 31. The recess 45 may be formed by a perforation of the plate 41, for example of its vertical main part located against the wall 31. The flange 111 of the drill 11 towards the inside of The pool is located in the fixing part 440 to the upper leg 43 of the plate 41.

In one embodiment, the passage 45 is located between two legs 43 distant from each other. In this case, the shaft 8 and its end 81 pass through the recess 45 being located next to the upper fixing legs 43.

In another embodiment, the recess 45 may be located under one or more upper fixing legs 43.

In one embodiment, the part 7 is fixed or it can be fixed to the upper plate 44 and / or to the plate 41. The piece 7 can be integral with being made in one piece with the upper plate 44.

Thus, the invention dispenses with a dry pit on the side of the outer face 311 of the first wall 31. Thus, the box 12 may be arranged on a solid material, such as, for example, earth or embankments. Thus, it is not necessary to dig on the side of the outer face 311 to the level of the first tree 5, while higher heights N of water E are allowed on the side of the inner face 310. The second tree 8 advantageously passes through a small passage 7 that can be sealed and placed just below the drill 11.

Of course, in box 10, the conical pins 904 and 906 and the angle change 905 can be replaced by a different orientation of the motor 10 so that the shaft 903 is parallel to the shaft 8.
