The water inlet pipe 4 of the invention is provided with a device for filtering rainwater, and the rainwater can enter the water bag 3 through the switch valve 5 after being filtered.

The hoist 8 of the present invention adopts the prior art. The motor in the hoist 8 is a self-locking motor, and after the hoist 8 pulls the movable floor 6 to vertically move upwards for a required distance through the steel wire ropes 7, the movable floor 6 can keep the height position after moving under the pulling of the four steel wire ropes 7 uniformly distributed at four corners of the movable floor without pressing the water bag 3 below the movable floor 6, so that rainwater is guaranteed to smoothly enter the water bag 3 through the water inlet pipe 4 to collect and store the rainwater.

The working process of the invention is as follows: in the initial state, the movable floor 6 is located at the bottom in the basement 1, the hook 11 is matched with the clamping slot 10 on the corresponding slat 9, the clamping block A18 is contacted with the corresponding clamping block B17, and the spiral spring 16 is in a pre-compression energy storage state. The multi-stage telescopic rod A22 and the multi-stage telescopic rod B35 in the step ladder mechanism 21 are both in the longest stretching state, and the lowest telescopic joint A23 in the multi-stage telescopic rod A22 is in contact with the movable floor 6.

The single-layer shelf 42 has shelves 87 with different heights of goods placed thereon. The height of the goods placed on the partition 87 of the top single-layer shelf 42 is lower than the top end of the support rod 43 in the top single-layer shelf 42, so that the pressing rod 61 can conveniently interact with the top in the basement 1. Spring D56, spring E63, spring F68, and spring H82 are all in a pre-compressed energy storage state. The two springs G78 in each single layer shelf 42 are in a stretched energy storage state. The springs C54 are all in compression. The trigger bar B60 is located a distance from the lower triangle B58.

When the rainwater collecting device is used for collecting rainwater, the four winches 8 are controlled to operate simultaneously, the four winches 8 respectively pull the movable floor 6 upwards through the corresponding steel wire ropes 7, the four winches 8 stop operating when the movable floor 6 reaches a certain height according to rainfall conditions and rainwater collection amount in a specific time period, the movable floor 6 stays in a half-empty state under the pulling of the four winches 8 which stop operating because the motors in the winches 8 are self-locking motors, and the eight hooks 11 are respectively matched with the clamping grooves 10 on the corresponding laths 9 to prevent the suspended movable floor 6 from falling when the four winches 8 fail accidentally.

During the raising process of the movable floor 6, the plurality of slots 10 on the slat 9 interact with the inclined surfaces a12 on the corresponding hooks 11 in sequence, so that the hooks 11 are driven by the corresponding spiral springs 16 to swing back and forth around the central axis of the corresponding transmission shaft 13 towards the wall surface direction without obstructing the movement of the slat 9. When the movable floor 6 reaches the destination position, a certain slot 10 on the lath 9 is matched with the hook 11 and forms a fixed position for the suspended position of the movable floor 6.

In the process of vertical upward movement of the movable floor 6, the lowest expansion joint A23 in the step mechanism 21 firstly contracts upward under the action of the movable floor 6, the lowest expansion joint A23 drives the corresponding trigger rod A32 to approach to the upper triangular block A39, and the spring B33 between the lowest expansion joint A23 and the two expansion joints A23 which are mutually sleeved is further compressed to store energy.

When a trigger rod A32 arranged on the lowest expansion joint A23 meets an inclined plane B40 of an upper triangular block A39, the lowest expansion joint A23 contracts to the limit, the triangular block A39 drives a corresponding limit block A29 to contract towards the corresponding sliding groove A25 and release the contraction limit of two expansion joints A23 which are positioned above the lowest expansion joint A23 and are mutually sleeved, and a spring A30 nested on the limit block A29 which generates the movement is stretched to store energy. Since the contraction restriction between two adjacent expansion joints a23 above the lowermost expansion joint a23 is released, the lowermost expansion joint a23 contracted to the limit drives the expansion joint a23 fitted thereto to perform the second-joint contraction. In this way, the lower expansion joint A23 is sequentially contracted upwards section by section, and the contracted expansion joint A23 drives the corresponding pedal 34 to synchronously move, contract and recover. The pedal 34 for retraction and recovery drives the corresponding two telescopic joints B36 to retract synchronously upwards.

The elastic plate 86 on the sliding sleeve B85 arranged on the pressure lever 61 presses the lower L-shaped lever B84, the L-shaped lever B84 drives the corresponding limit block C80 to release the limitation on the n-shaped push plate 76 in the pushing mechanism 71 on the top single-layer shelf 42, and the spring H82 nested on the limit block C80 is further compressed to store energy. The n-shaped push plate 76 in the pushing mechanism 71 in the top single-layer shelf 42 pushes the goods on the partition 87 in the top single-layer shelf 42 higher than the top end of the top strut 43 away from the partition 87 at the moment pulled by the corresponding two springs G78 so as to increase the compression amplitude of the press rod 61 in the sliding groove B46.

When the four pressure levers 61 contract to the limit, the trigger lever B60 mounted on the pressure lever 61 drives the corresponding limit block B55 to completely release the limit to the contraction motion of the two support rods 43 with the top ends sleeved with each other through the interaction with the inclined plane C59 on the lower triangular block B58, and the spring D56 nested on the limit block B55 is further compressed to store energy.

Under the reset action of the spring H82, the limiting block C80 is reset instantly.

At this time, under the continued pressing of the top in the basement 1, the four pressing rods 61 drive the four supporting rods 43 in the top single-layer shelf 42 to perform downward contraction movement relative to the lower single-layer shelf 42, and the four springs C54 between the two top single-layer shelves 42 are further compressed to store energy at the same time. The four support rods 43 of the top single-layer shelf 42 respectively drive the pressing block 70 mounted thereon to approach towards the lower sliding rod 65, and the elastic plate 86 mounted on the sliding sleeve B85 mounted on the support rods 43 of the top single-layer shelf 42 approaches towards the lower L-shaped rod B84.

The n-type push plate 76 of the pushing mechanism 71 on the single-layer shelf 42 located below the top single-layer shelf 42 pushes the goods having a height greater than the minimum distance between the adjacent two partitions 87 on the partitions 87 in the single-layer shelf 42 located below the top single-layer shelf 42 away from the partitions 87 at the instant of pulling by the corresponding two springs G78 to increase the magnitude of compression between the adjacent two single-layer shelves 42.

When the four support rods 43 in the top single-layer shelf 42 are contracted downwards to the limit, the press blocks 70 arranged on the four support rods 43 in the top single-layer shelf 42 interact with the lower slide rods 65, the slide rods 65 drive the corresponding limit blocks B55 through the corresponding L rods A64 to completely remove the limit on the contraction movement of two mutually sleeved single-layer shelves 42 positioned below the top single-layer shelf 42, and the spring D56 nested on the limit block B55 is further compressed to store energy. The spring H82 nested on the limiting block C80 is compressed to the limit, the top end of the lower L-shaped rod B84 breaks through the upper elastic plate 86 to enable the elastic plate 86 to deform and swing, and the upper end of the L-shaped rod B84 penetrates through the elastic plate 86 arranged on the side wall of the supporting rod 43 of the top single-layer shelf 42 and loses the pressing force of the elastic plate 86. Under the reset action of the spring H82, the limiting block C80 is reset instantly.

In this way, the single-layer shelves 42 of the shelf mechanism 41 are sequentially contracted section by section from top to bottom to accommodate the elevation of the raised floor 6.

When the movable floor 6 is raised to the target height, the switch valve 5 on the water inlet pipe 4 is opened, so that rainwater on the ground enters the water bag 3 through the specific collecting device and the water inlet pipe 4, and along with the increase of the rainwater collecting amount, the water bag 3 gradually rises and is raised to be gradually close to the movable floor 6. When the rainwater collection of the water bag 3 is finished, the switch valve 5 is closed.

As the rainwater in the water bladder 3 is used, the water bladder 3 gradually restores the initial state as the collected rainwater decreases. When a rainy season or a winter season comes, the driving lever 20 drives the corresponding transmission shafts 13 to rotate, the transmission shafts 13 provided with the driving lever 20 drive the two bevel gears 19 arranged at the two ends of the transmission shafts to synchronously rotate, the two bevel gears 19 respectively drive the two transmission shafts 13 at the two sides to synchronously rotate through the bevel gears 19 arranged on the two transmission shafts 13 at the two sides, the two transmission shafts 13 at the two sides respectively drive the fourth transmission shaft 13 to synchronously rotate through the bevel gears 19 arranged on the two transmission shafts 19 and the bevel gears 19 arranged on the fourth transmission shaft 13, the four transmission shafts 13 respectively drive the two hooks 11 arranged on each transmission shaft 13 to swing towards the corresponding wall surface direction and remove the vertical movement limitation on the corresponding lath 9, the volute spring 16 corresponding to each hook 11 is further compressed to store energy, and the fixture block A18 is separated from.

Then, the four winches 8 are started to run reversely at the same time, and the four winches 8 respectively release the movable floor 6 downwards through the corresponding steel wire ropes 7. When the raised floor 6 reaches the initial position, the operation of the four winches 8 is stopped. Then, the shift lever 20 is swung reversely or the acting force on the shift lever 20 is removed, the shift lever 20 drives the four transmission shafts 13 to rotate reversely through a series of transmissions or the four transmission shafts 13 respectively rotate reversely under the restoring action of the corresponding two volute springs 16, the four transmission shafts 13 respectively drive the corresponding two hooks 11 to be matched with the corresponding clamping grooves 10 on the laths 9, and the clamping block A18 is in contact with the corresponding clamping block B17 again.

With the resetting of the movable floor 6, two adjacent telescopic joints A23 in the multi-stage telescopic rods A22 in the step ladder mechanism 21 are extended and reset under the resetting action of corresponding springs B33. When the two adjacent telescopic joints A23 return to the initial state, the limit block A29 instantly returns under the return action of the corresponding spring A30 and limits the contraction movement of the two adjacent telescopic joints A23 again, and the step mechanism 21 finishes returning.
