  • This upper assembly 200 consists of a load-bearing structure 202 that is anchored on a foundation 201 and at whose upper part a drive assembly 220 is disposed, wherein a drive pulley 221, such as a friction pulley or Koepe pulley, is integrated, which moves the cable loops, driven by a bi-directional rotary machine 223, which can operate as a motor to raise the masses and also operate as a generator and generate energy when the masses descend in the application of the system of the invention to the energy sector.

  • the coupling between the two may be direct or via a speed reducer (not shown in the figures).
  • the bi-directional rotary machine 223 may be connected to the power grid by means of an electronic power converter, equipped with a control device (not shown in the figures).
  • the drive assembly 220 has a braking system (not shown in the figures), in order to be able to halt it in emergency situations.
  • the upper assembly for deflecting 230 is disposed, comprising deflector pulleys 231, which are displaced by means of a deflector 232 along a number of beams 233 in solidarity with the load-bearing structure 202.
  • the lower assembly 210 includes the transfer assembly 240 equipped with a transfer pulley 241 that rotates, pulled by the cable loops, maintaining certain tension therein, limiting the oscillations of the mass.
  • the lower assembly for deflecting 250 is located, equipped with a few deflector pulleys 251 joined to a trolley 252 that travels along a few beams 253.
  • This lower assembly for deflecting 250 is equivalent to the upper assembly for deflecting 230, both moving in coordination, such that the cables remain vertical throughout the vertical displacement space.
  • Both the transfer assembly 240 and the lower assembly for deflecting 250 have a beam, which may be common or independent for each assembly (242, 253, respectively), that anchors said assemblies to the walls of the chamber 104.
  • the upper assembly for deflecting 230 and the lower assembly for deflecting 250 have their deflectors 232 and 252 in the appropriate position for the cables that guide the deflector pulleys 231 and 251 to transfer the mass 300a centrally in the vertical displacement space, by means of the coupling assemblies 261a and 261a', since the portions of cable 260a and 260a' run through the centre of said displacement space. Meanwhile, the other pair of coupling assemblies 261b and 261b' are free of load and move downward, following the path close to the wall 103 defined by the portion of cable 260b and 260b', respectively. In this way, the mass maintains ample and uniform clearance to the walls of the vertical displacement space, which avoids unsteadiness and potential collisions due to oscillations.
  • the deflectors 232 and 252 displace the transfer pulleys 231 and 251 to the position shown in Figures 4 and 5 , wherein the other portions of cable 260b and 260b' become those located in the central plane of the vertical displacement space.
  • This allows the next mass to be transferred 300b to be coupled by means of the coupling assemblies 261b and 261b' and, when the drive pulley 221 begins to rotate in the opposite direction to that of the first displacement, this mass 300b is raised centrally in the vertical displacement space.
  • the system allows the masses to be transferred successively and continuously from one level to the opposite level, with a path always centred in the vertical displacement space, and in such a way that all displacements of the cable are used to transfer a mass.
  • one pair of coupling assemblies 261a and 261a' and the other pair of coupling assemblies 261b and 261b' are alternately employed, of which the pair carrying the mass is always centred in the vertical displacement space. This is achieved thanks to changing the position of the transfer pulleys 231 and 251 at the end of each travel path, after which the direction of rotation of the drive pulley 221 is reversed.
  • FIG 6 an enlarged detail A of Figure 1 according to an alternative embodiment of the system of the invention is shown, wherein the drive pulley 221 is located on the ground to one side of the vertical displacement space, in a disposition similar to that commonly used in mining facilities.
  • This configuration includes an additional assembly of deflector pulleys 203 at the upper level of the vertical displacement space which, unlike the deflector pulleys 231, remain fixed, since their function is to transfer the cables arriving from the drive pulley 221 to the deflector pulleys 231.
  • FIG. 7 another alternative embodiment of the system of the invention is shown, wherein the drive pulley 221 is also located on the ground to one side of the vertical displacement space, but the need for the additional assembly of deflector pulleys 203 is avoided, and the turret-like structure supporting all the pulleys disposed over the vertical of the vertical displacement space is dispensed with, using instead a forked swing arm 234, on which a single set of deflector pulleys 231 is disposed, capable of bringing one or another portion of the cable to the position centred in the vertical displacement space by means of adjustment of the angle of the arm, regulatable by means of actuators 235 or other equivalent elements.
  • This swing arm may be anchored to the ground by means of a foundation 201 for each of its joints, by means of a foundation common to both joints or by means of a single foundation that serves as an anchor both for said joints and for the drive assembly 220.
  • the system according to an embodiment of the invention further comprises coupling assemblies which, together with a specific design of the masses, allows the automatic coupling and uncoupling and releasing of said masses at the ends of their vertical travel path to be carried out, without the need for intervention by operators, and in a rapid manner, which is particularly important for the application of storage of energy, to minimize the impact of transitions in which the flow of energy delivered (or consumed, during the recharge of the installation) is affected.
  • the system according to this embodiment is very robust and reliable, since for the coupling and uncoupling of the masses it is not necessary to use drives or moving parts in the coupling assemblies nor in the masses, guaranteeing the safety of operations and minimizing the possibility of failures.
  • each portion of cable 260a and 260a' has a coupling assembly 261a and 261a', which in turn consists of an upper element 262 and 262' and a lower element 272 and 272'.
  • the upper and lower element of each coupling assembly may form part of a single component or be manufactured independently and then installed on the cable at the appropriate distance.

  • the mass 300b has a few holes 301 and 301' and a few upper supports 362 and 362' identical to those described.
  • FIGS 9A to 9C the sequence of insertion and coupling of the mass 300a is shown by means of cross-sectional and plan views, wherein, in addition to the involvement of the coupling assembly described, an extraction means is used, which enables the insertion and extraction of the masses in the vertical displacement space.
  • said extraction means shall consist of a platform capable of being horizontally displaced between the vertical displacement space and a space adjacent to the same, at least one extraction means being disposed at the starting level and another at the destination level of mass displacement.

  • the insertion movement continues until the mass is in the coupling position, centred in the vertical displacement space.
  • the mass 300b has identical slots 303 and 303', but when inserted into the vertical displacement space, this occurs rotated by 180°, such that its slots are oriented with their open end towards the portions of cable 260a and 260a'. Therefore, the masses 300a and 300b will be inserted into the vertical displacement space from opposite sides.
  • the cables begin their ascent, so that the couplings are inserted into the holes of the mass 300, 301' until they reach their coupling position and, as the ascent continues, the upper coupling draws the mass upwards, as shown in Figure 9C , and it is then possible to remove the extraction means whereon the mass was resting.
  • the uncoupling of a mass 300a requires that it be at a higher level than the extraction means 500, as may be seen in Figure 9D .
  • the mass 300a will already be higher than the extraction means 500 throughout the entire vertical displacement, but in the event that the destination level is the higher level, it will be necessary that the mass that is ascending should continue to rise until it reaches a sufficient height above the extraction means.
  • the extraction means 500 is inserted into the vertical displacement space, as may be seen in Figure 9D , and the mass 300a begins to descend, coupled to the portions of cable 260a and 260a' by means of the couplings 262, 262', 272 and 272', approaching the extraction means 500.
  • the mass 300b since it will have been inserted into the vertical displacement space rotated 180° with respect to the position of the mass 300a shown in Figure 9F , will have the opening of its slots inverted, so the masses 300a and 300b will be extracted from the vertical displacement space towards opposite sides.

  • the slots in the mass are substituted by slots 303 and 303' in the supports themselves, which can also incorporate grooved elements, which have the function of facilitating the guiding of the cable to the lifting position.
  • This embodiment has the advantage that, in order to insert or extract the mass, it is sufficient that the couplings are below their corresponding support, as is observed in Figure 11B , without the need that all of them have to come to be below the mass, which makes the coupling/uncoupling operation faster.
  • Another advantage is that, by maximizing the distance between cables, stability is improved in the face of any tendency of the mass to rotate around a vertical axis (see Figure 10D ).

  • the wagon runs through the interior of the gantries 621 of the lower level structure for storage of masses 610a, maintaining its platform 554 elevated to prevent the mass from interfering with the support beams 623, as is appreciated from section B of this figure.
  • the wagon 510a When it arrives at its destination, the wagon 510a halts and the thrusters 553 lower the platform 554 until the mass 300a rests on the support beams 623 in its storage position, as is seen in section C of Figure 14C . These support beams rest on brackets 622, solidary to the gantries 621. Once the mass is resting on said support beams, the wagon can now return to the vertical displacement space, maintaining the platform in its lowered position.
  • the movement of the wagons and their platforms can be achieved by electric motors integrated in the wagon, which would be powered via a third rail system, equivalent to that used in some railway or underground railway lines, or indeed by equipping the wagon with batteries that would be charged at a charging point located at a certain point of the track, to which the wagon would move when not working.
  • Another alternative for moving the wagon would be to use a system of external cables and pulleys, similar to the procedure used in funicular railways.
  • FIG. 15A to 15D The sequence of uncoupling, extraction, transport and unloading of the masses at the lower level of the vertical displacement space is shown in Figures 15A to 15D .
  • the arrows indicate the movements of the elements with the system of the invention operating to disengage the masses that descend via the cables and to take them to their storage position. If the order of the figures and the direction of the arrows are reversed, the sequence of loading, transport, insertion and coupling of the masses at the lower level is obtained, wherein the masses will be taken from their storage position to the vertical displacement space, where they are coupled for lifting.
  • the first wagon 510a already has the mass 300a resting thereon, while its couplings continue to descend to a position in which they do not interfere with the removal of the wagon loaded with the mass. Meanwhile, the second wagon 510b unloads the mass 300b into the lower level structure for storage of masses.
  • the first wagon 510a begins to be displaced to take its mass 300a to its storage position, while the second wagon 510b, already freed from its load, returns toward the vertical of the vertical displacement space to collect the next mass to descend to the lower level of the vertical displacement space.
  • the masses 300a and 300b have to be inserted into and extracted from the vertical displacement space on opposite sides, so it is necessary for the tracks 400a and 400b, on which the wagons 500a, 500b will be displaced, to be disposed on opposite sides of the vertical displacement space, as shown in Figure 16A .
  • the tracks are on bridge beams 420 in the part of their travel path that crosses the vertical displacement space.
  • the upper level structures for storage of masses 600a and 600b are also shown, disposed on the corresponding side of the vertical displacement space.
  • the galleries can be advantageous for the galleries to have a small incline, the level being in this case slightly higher at the ends opposite to the vertical displacement space. In this way, when the installation is working in discharge mode, additional energy to that of the vertical displacement is generated in the passage of the masses through the galleries from their storage position until they are coupled for their descent down the vertical displacement space,. On the contrary, when the installation is being recharged, the energy consumption will increase due to the movement of the masses from the vertical displacement space to their storage position.
  • the masses that rise to the upper level of the vertical displacement space have to continue to ascend to a level slightly higher than that of their removal, in order to be able to subsequently uncouple them in their downward movement.
  • the masses must make a short upward movement to engage them, prior to proceeding with their descent to the lower level of the vertical displacement space.
  • the transport and unloading of the masses on the upper level structures for storage of masses 600a and 600b, and the loading and transport of the masses from said structures will be carried out in the same way as at the lower level, as described in Figures 14A, 14B and 14C , thus incorporating in said structures and in the wagons employed the same elements as their lower level counterparts.
  • the structures for storage of masses and/or the wagons may have geometric differences or additional elements with respect to those of the upper level, as a consequence of the fact that, at the upper level, the masses in their vertical movement must cross the section of the vertical displacement space located at the level of the tracks, which implies a difficulty so that the masses do not interfere with the tracks nor with the bridge beams.
  • FIG 17A interference is avoided by employing a mass 300a with a reduced width, while a track with a very large separation between rails is utilised, such that the mass can be accommodated between the bridge beams.
  • the cables run through the space that is between the rails, and the masses and wagons have to be slotted for their extraction.
  • Figure 16B shows this solution in a three-dimensional view.
  • the track is interrupted in its passage through the vertical displacement space, therefore a track with standard separation can be employed.
  • the mass can be wider and the cables are further apart, being carried on the outside of the mass by means of artificial supports equivalent to those shown in Figures 11A and 11B , so therefore neither the mass nor the wagons have to be slotted.
  • a conventional wagon cannot be located on the vertical of the vertical displacement space for collecting or delivering masses to the system.
  • the masses can be transferred from the vertical of the vertical displacement space to the wagons and vice versa by means of a bridge crane or other auxiliary equipment.
  • Another option is to have a retractable or swing bridge that is deployed to bridge the gap on the vertical of the displacement space, enabling conventional wagons to be placed in the position necessary for the coupling or uncoupling of the masses, and that folds back after completing these manoeuvres, thus preventing interference in the vertical displacement of the masses.
  • Figures 18A to 18D the sequence of uncoupling, extraction, transport and unloading of the masses at the upper level of the vertical displacement space is shown, using a configuration such as that shown in Figure 17A .
  • the arrows indicate the movements of the elements with the system operating to uncouple the masses that ascend via the cables and to take them to their storage position. If the sequence and direction of the arrows are reversed, the sequence of loading, transport, insertion and coupling of the masses at the upper level is obtained, with the system operating to move the masses from their storage position to the vertical displacement space, where they are coupled for their descent towards the lower level.
  • the wagon 500a on the right-hand track travels into the vertical displacement space to collect the mass 300a that ascends through the vertical displacement space, and which, thanks to the large separation between rails, can pass between the bridge beams without interference.
  • the wagon 500b on the left-hand track is taking the mass 300b, that has previously been raised, to its storage position.
  • FIG 19 a special wagon, according to an embodiment of the system of the invention, is shown, that can be employed with a configuration such as that of the embodiment shown in Figure 17B , being able to collect and deliver masses on the vertical of the vertical displacement space, despite the track being interrupted in this section.
  • the wagon 520 is considerably longer than conventional wagons, as it has an overhang ahead of the wheels closest to the vertical displacement space, at the end of which the platform 554 is located. In this way, the wagon can collect the masses on its platform on the vertical of the vertical displacement space, even though the track 400a is interrupted in this space.
  • the wagon incorporates a counterweight 521 of sufficient weight.
  • the wagon does not require slots nor holes to be able to extract the masses from the vertical displacement space.
  • FIG 21 a special wagon according to another embodiment of the invention is shown, which can be employed with a configuration such as that shown in the embodiment of Figure 17B , which is capable of collecting and delivering masses at the vertical of the vertical displacement space, even though the track is interrputed in this section.
  • the wagon 530 is longer than a conventional one.
  • the platform 554 is mounted on a trolley 531 that can be displaced between one end of the wagon and the other.
  • the arrangement of the wagon wheels enables it to approach the vertical displacement space and cross it, although certain pairs of wheels remain temporarily in the air, since those that do rest on the track 400a or 400b give it sufficient stability.
  • the front wheels could be replaced by support elements, so that the rest of the wheels of the wagon are indeed always kept on a section of track, while these support elements would reach the other side of the vertical displacement space, and could rest on a surface prepared for this purpose, adjacent to the vertical displacement space.
  • the wagon could only carry masses along one of the tracks 400a or 400b, it being necessary to use at least one such wagon on each.
  • the separation between cables means that this wagon does not need slots or holes to be able to extract the masses from the vertical displacement space.
  • the trolley returns to its initial position at the end of the wagon, at which time the wagon can begin its movement towards the storage area, as may be seen in Figure 22F , taking advantage of the weight of the mass to increase its stability while the wheels that are over the vertical displacement space remain in the air.
  • the mass transport and unloading manoeuvre is performed at the corresponding upper level structure for the storage of masses, which is not detailed in this sequence of figures, since it is equivalent to that of conventional wagons, shown in previous figures.
  • the successive displacement of masses is performed alternating between one mass 300a and another 300b, so that the masses 300a are displaced vertically by means of the first portions of cable 260a and 260a' and, horizontally, according to the level considered, by the tracks 400a and 410a, located on the side of the vertical displacement space closest to said portions of cable, and subsequently unloaded into the corresponding storage structures 600a and 610a.
  • the masses 300b are always displaced vertically by the second portions of cable 260b and 260b' and, horizontally, according to the level considered, along the tracks 400b and 410b, located on the side of the vertical displacement space closest to said portions of cable, and then unloaded onto the corresponding storage structures 600b and 610b.
