Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Examples

Referring to fig. 1-7, the present embodiment provides a garden rainwater collecting device, as shown in fig. 1, including a water collecting plate 2 and a water storage cavity 1 pre-buried underground for storing water, wherein the water storage cavity 1 may be a tank structure formed by directly digging and pouring underground, or may be a tank buried underground, and the water storage cavity 1 is formed by the inside of the tank.

As shown in fig. 2, the water collecting plate 2 is mainly used for receiving rainwater and guiding the rainwater, and the water collecting plate 2 includes two support arms 21 arranged oppositely and a water diversion surface 22 arranged between the two support arms 21 and used for guiding the rainwater, wherein the water diversion surface 22 can be specifically formed by a hard plate body fixedly arranged between the two support arms 21 or a light structure such as a waterproof fabric or a film fixed between the two support arms 21, and the water diversion surface 22 is preferably formed by adopting the light structure in the embodiment, so that the weight of the whole water collecting plate 2 is reduced.

As shown in fig. 1 and fig. 2, the collecting device further includes a collecting box 3, the collecting box 3 is pre-buried underground and has a cavity 31 therein for accommodating the water collecting plate 2, and preferably, the collecting box 3 in this embodiment has a rectangular box structure, and a rectangular cavity 31 is formed therein; wherein the collection tank 3 is located at the upper part of the water storage cavity 1 and the bottom of the cavity 31 is provided with a through hole so as to be communicated with the water storage cavity 1, and the rainwater entering the cavity 31 can fall into the water storage cavity 1 through the through hole.

The open setting in cavity 31 upper end, with cavity 31 upper end open setting one guarantee that water collecting plate 2 can normally get in and out collection case 3, second guarantee that rainwater can fall into cavity 31, also can see from this that collection case 3's effect has two in this embodiment, and water collecting plate 2 is accomodate to one of them, and its two is leading-in rainwater water storage chamber 1.

In addition, in order to reduce the earth on the ground falling directly into the collection box 3, at least one section of the top of the collection box 3 in this embodiment extends out of the ground, and reference is made to the state shown in fig. 1.

As shown in fig. 2, 3 and 5, two sliding seats 4 capable of moving vertically in the cavity 31 are arranged in the cavity 31, and the two sliding seats 4 are respectively arranged at the left side and the right side of the cavity 31; the lower ends of the two support arms 21 are respectively rotatably mounted on the two slide bases 4, wherein the rotation axis of the support arms 21 is vertical to the vertical direction.

A stirring piece 5 for stirring the water collecting plate 2 to turn over is arranged on the sliding seat 4, and a linkage assembly for realizing linkage with the stirring piece 5 is arranged between the sliding seat 4 and the collection box 3;

the sliding seat 4 moves vertically to form a vertical moving path, and the vertical moving path of the sliding seat 4 sequentially comprises a holding section and a linkage section from bottom to top, as shown in fig. 4, wherein the part L1 can be understood as the holding section, and the part L2 can be understood as the linkage section; the action process of the water collecting plate 2 in the process of the sliding seat 4 along the vertical moving path is as follows:

when the slide seat 4 vertically ascends or descends in the holding section, the stirring piece 5 keeps the water collecting plate 2 in a folded state and passes through the cavity 31; the folded state here means that the water collection sheet 2 is kept substantially upright, although it is allowed to incline somewhat as long as it does not touch the side wall of the cavity 31 in the folded state, and it is specifically referred to the state shown in fig. 6 and 7.

When the slide carriage 4 slides upwards to the linkage section position, most of the area or all of the water collecting plate 2 extends out of the cavity 31; so as to ensure that the water collecting plate 2 can be unfolded or folded smoothly when the sliding seat 4 is lifted vertically at the linkage section.

When the sliding seat 4 moves upwards in the linkage section, the stirring piece 5 drives the water collecting plate 2 to turn forward under the action of the linkage assembly, so that the water collecting plate 2 is gradually unfolded to one side at the upper end of the collection box 3 and finally enters an unfolding state, and particularly, the state shown in fig. 1 and 2 can be referred to, in the unfolding state, the water collecting plate 2 is obliquely arranged, the lower end of the water collecting plate 2 is positioned right above the cavity 31, and thus rainwater falls on the water collecting plate 2 in the unfolding state, and the rainwater can finally fall into the collection box 3 from the lower end along the inclined plane of the water collecting plate 2.

When the sliding seat 4 moves downwards in the linkage section, the water collecting plate 2 starts to switch from the unfolding state to the folding state, and at the moment, the stirring piece 5 drives the water collecting plate 2 to reversely turn over under the action of the linkage assembly, so that the water collecting plate 2 gradually enters the folding state, as shown in fig. 6.

In order to better understand the present embodiment, the following will specifically describe the process by taking the case where the water collection sheet 2 is switched from the housed state to the expanded state in the housing box 3:

first, the water collection sheet 2 is accommodated in the collection box 3 substantially entirely in a collapsed state, as shown in fig. 7; then, the sliding seat 4 moves upwards along the holding section, the linkage component and the deflector rod 52 do not generate linkage in the running process of the holding section, and the water collecting plate 2 moves upwards along with the sliding seat 4 in a state of being kept folded under the holding of the deflector rod 52; then the sliding seat 4 starts to enter the linkage section, and in the operation process of the linkage section, the linkage assembly acts on the deflector rod 52, so that the deflector rod 52 starts to drive the water collecting plate 2 to forward overturn, the water collecting plate 2 is gradually unfolded to one side at the upper end of the collection box 3, and finally the water collecting plate enters an unfolding state, as shown in a state of fig. 2, and the whole switching process is realized.

With the above arrangement, in windy weather, the water collecting plate 2 can be stored in the storage tank 3 as shown in fig. 7, and the storage tank 3 is buried under the ground, so that the water collecting plate 2 is hardly exposed or hardly exposed to the ground, so that even if windy weather is present, the water collecting plate 2 is hardly turned over or broken.

In the rainy day, as shown in fig. 1 and 2, the water collecting plate 2 can be unfolded at the side of the collection box 3 by sliding the sliding seat 4 upwards, and the water collecting plate enters an unfolding state, at this time, rainwater can be guided into the collection box 3 along the water collecting plate 2, and finally, the rainwater is guided into the water storage tank for storage.

In addition, the lifting and overturning of the water collecting plate 2 can be realized by means of the vertical movement of the sliding seat 4 in the embodiment, so that the lifting and overturning actions of the water collecting plate 2 can be finished by only one power source for driving the sliding seat 4 to move vertically, and two power sources are not required to be respectively arranged for controlling the lifting and overturning actions of the water collecting plate 2. Thus, the power source can be saved.

Furthermore, in this embodiment, the overturning and lifting of the water collecting plate 2 are not always performed synchronously, and the water collecting plate 2 is overturned to one side only when the sliding seat 4 is lifted to the linkage section position, and when the sliding seat 4 is lifted to the linkage position, most of the area of the water collecting plate 2 is basically extended from the upper portion of the cavity 31, and at this time, the water collecting plate 2 is overturned again so as not to be interfered by the collecting box 3. Otherwise, the water collecting plate 2 is supposed to rise and turn synchronously all the time, so that the water collecting plate 2 starts to turn and spread gradually to one side in the rising process of the collecting box 3, and when the water collecting plate 2 is abutted against the inner wall of the collecting box 3, the water collecting plate cannot continue to turn, and the corresponding rising action is difficult to continue.

Finally, in this embodiment, the water collecting plate 2 is to be finally gathered in the collection box 3 in a gathered state, and the water collecting plate 2 is not directly put down and stored in an unfolded state, so that the gathered collection box 3 occupies smaller space in the transverse direction, and the collection box 3 does not need to be designed too widely.

In addition, it should be noted that the water collecting plate 2 may be designed in one group, or may be designed in two groups, preferably in two groups, and the overall water receiving area of the two groups of the water collecting plates 2 is larger than that of one group of the water collecting plates 2, which is more favorable for collecting rainwater, so in this embodiment, two groups of water collecting plates 2 are taken as an example.

As shown in fig. 2 and 5, the two groups of water collecting plates 2 have substantially the same structure and are symmetrically arranged on the front and rear sides of the collection box 3, and the two groups of water collecting plates 2 move synchronously, specifically, each group of water collecting plates 2 is provided with the stirring piece 5.

The toggle piece 5 is specifically constituted by: as shown in fig. 6, the toggle member 5 includes a swing arm 51 and a toggle lever 52, one end of the swing arm 51 is rotatably connected to the back side of the slide 4 to serve as a fixed end, and the other end is served as a free end to be fixed with the toggle lever 52; the rotation axis of the swing arm 51 is parallel to the rotation axis of the water collection sheet 2.

Correspondingly, kidney-shaped holes 211 extending along the length direction of the support arm 21 are formed in the support arm 21, and the deflector 52 movably penetrates through the kidney-shaped holes 211, so that the deflector 52 is driven to rotate by the swing arm 51, and the deflector 52 moves in the kidney-shaped holes 211 to drive the support arm 21 to turn forward or reverse, so that the water collecting plate 2 is turned.

The specific structure of the linkage assembly in this embodiment is: as shown in fig. 4-6, the linkage assembly includes a rack 61, a gear 62, and a driven shaft 63; the driven shaft 63 is rotatably disposed on the back side of the slide 4, the rotation axis of the driven shaft 63 is perpendicular to the rotation axis of the swing arm 51, and the swing arm 51 is driven to rotate by the rotation of the driven shaft 63.

The gear 62 is coaxially fixed on the driven shaft 63, as shown in fig. 4 and 6, the rack 61 is located at the position of the holding section and vertically fixed on the inner side wall of the cavity 31, and the position of the gear 62 in the vertical direction can be understood as the position of the slide 4 in the vertical direction, and when the gear 62 starts to mesh with the rack 61 from bottom to top, the slide 4 can be considered to start to enter the holding section. When the slide 4 is lifted or lowered in the linkage section, the gear 62 is in a state of meshing with the rack 61.

Thus, when the slide carriage 4 moves up or down in the linkage section, under the action of the rack 61, the gear 62 rotates simultaneously with the upward or downward movement of the slide carriage 4, so as to drive the driven shaft 63 to rotate forward or backward, and the driven shaft 63 drives the swing arm 51 to rotate.

In order to realize that the driven shaft 63 rotates to drive the swing arm 51 to rotate, in this embodiment, as shown in fig. 6, a fixed end of the swing arm 51 is in a turbine 511 structure, and a worm section 631 meshed with the turbine 511 is disposed at a position of the driven shaft 63 corresponding to the turbine 511. The swing arm 51 and the driven shaft 63 are in linkage through the transmission mode of the worm wheel and the worm, so that the driven shaft 63 rotates to drive the worm section 631 to rotate, and the worm section 631 drives the worm wheel 511 to rotate, and the swing arm 51 can rotate along with the worm wheel 511.

In addition, it should be noted that, in this embodiment, the connection between the swing arm 51 and the driven shaft 63 is realized by adopting a worm gear connection mode, so as to facilitate the principle of unidirectional self-locking of the worm gear, that is, the worm gear can drive the worm gear 511 to rotate, but the worm gear 511 cannot drive the worm gear to rotate.

It is specifically contemplated that, as is known from the foregoing process, when the slide 4 is lifted in the holding section, the gear 62 is separated from the rack 61, and at this time, the gear 62 has no possibility of rotating due to the clamping of the rack 61, so that the driven shaft 63 has possibility of rotating, and thus the swing arm 51 also rotates and cannot hold the water collecting plate 2, and at this time, if there is no self-locking limitation of the worm and the worm section 631, the water collecting plate 2 can freely tip over to one side and collide with the side wall of the cavity 31, and thus the water collecting plate 2 can continuously rub against the side wall of the cavity 31 in the lifting or lowering process, and abrasion of the side wall of the cavity 31 and/or the water collecting plate 2 can be accelerated.

However, the limitation of the worm wheel 511 and the worm section 631 is not the same, even if the gear 62 does not have the clamping of the rack 61, the self-locking property of the worm wheel 511 and the worm section 631 makes the worm capable of clamping the worm wheel 511, and further makes the worm wheel 511 unable to rotate, so that the swing arm 51 also unable to rotate, so that the swing arm 51 can support the water collecting plate 2, and the water collecting plate 2 keeps in a folded state and moves vertically in the holding section, so as to prevent friction between the water collecting plate 2 and the side wall of the cavity 31.

In addition, it should be noted that, in order to cooperate with two sets of water collection plates 2 at the same time, as shown in fig. 6, the driven shaft 63 forms two sections of worm sections 631 on two sides of the gear 62, the rotation directions of the two worm sections 631 are opposite, the swing arms 51 corresponding to the two corresponding water collection plates 2 are each provided with a turbine 511, and the two turbines 511 are respectively meshed with the two worm sections 631, so that the driven shaft 63 can simultaneously drive the two water collection plates 2 to synchronously rotate in opposite directions while rotating, thereby realizing synchronous folding or unfolding of the two water collection plates 2.

In order to facilitate and save effort in controlling the vertical movement of the sliding seat 4, as shown in fig. 1 and 2, the collecting device further comprises a driving mechanism for driving the sliding seat 4 to slide vertically, preferably, the driving mechanism drives the two sliding seats 4 to move synchronously in the same direction, specifically, the two sliding seats 4 are connected through a frame 7, the driving mechanism is used for driving the frame 7 to move vertically, so as not to interfere with the folding or unfolding of the water collecting plate 2, and in this embodiment, as shown in fig. 5, the frame 7 is located at the bottom of the sliding seat 4. The driving mechanism is connected with the frame 7, so that the two sliding seats 4 can be driven to synchronously move.

The driving mechanism can adopt a screw rod linear module, as shown in fig. 1 and 2, and specifically comprises a motor 82 and a screw rod 81, wherein the screw rod 81 extends vertically, the lower end of the screw rod 81 is rotationally connected to the bottom wall of the cavity 31, and the screw rod 81 is in threaded connection with the frame 7; the motor 82 is arranged on the outer side of the top of the collection box 3 and is used for driving the screw rod 81 to rotate, and any mode such as gear transmission, belt transmission or chain transmission can be adopted between the motor 82 and the screw rod 81 to realize transmission; thus, the motor 82 drives the screw rod 81 to rotate so as to drive the frame 7 to vertically move, and further drive the two sliding seats 4 to vertically move. In this embodiment, two groups of driving mechanisms are preferably arranged and symmetrically arranged at two sides of the frame 7, and the two driving mechanisms jointly drive the frame 7 to move vertically.

Of course, in other alternative embodiments, the driving mechanism may also be a telescopic structure like a cylinder, a hydraulic cylinder.

For guiding the vertical movement of the frame 7, in this embodiment, as shown in fig. 4, a guide rail 91 extending vertically is provided on a side wall of the cavity 31, a slide block 92 is provided on a side wall of the frame 7, and the slide block 92 is slidably disposed on the guide rail 91.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
