[0005] In order to improve the drainage effect of a garden, the application provides a garden drainage device.

[0006] The garden drainage device provided by the application adopts the following technical scheme:

[0007] The garden drainage device comprises a vertically arranged drainage pipe and an underground pipe communicated with a lower pipe opening of the drainage pipe, a grating plate is arranged at an upper pipe opening of the drainage pipe, and a driving member for driving the grating plate to ascend and descend is arranged in the drainage pipe; the upper pipe opening of the drainage pipe is formed with a sink, grating assemblies are arranged around the grating plate, each grating assembly comprises a plurality of grating blocks, the grating blocks away from the grating plate are hinged to the sink, the grating blocks close to the grating plate are hinged to the grating plate, the grating blocks are arranged in a sliding and telescopic mode between adjacent grating blocks, and the grating blocks in any grating assembly are arranged in a grating mode.

[0008] Under normal circumstances, the grating plate and all the grating blocks are located in the sink of the drainage pipe to preliminarily filter leaves and branches; when the fallen leaves and sundries are covered on the grating plate, the drainage effect of rainwater is affected, at this time, the driving member drives the grating plate to ascend, the grating blocks are driven to rotate by the grating plate, and the adjacent grating blocks are telescopic to adapt to the ascension of the grating plate, the ascension of the grating plate lifts the fallen leaves and sundries, and all the grating blocks are arranged in an inclined mode to make the fallen leaves and sundries slide and accumulate on the ground surface, under the condition that there is much water on the ground surface, rainwater enters the drainage pipe from the grating blocks to improve the drainage effect, and in addition, the relative sliding of the adjacent grating blocks increases the flow gap of rainwater to further improve the drainage effect.

[0009] Preferably, the driving member is arranged as a driving cylinder, which is arranged vertically upward, and the piston rod end of the driving cylinder is connected with the grid plate.

[0010] By using the above technical scheme, the driving cylinder is operated to make the piston rod extend and retract, thereby realizing the lifting movement of the grid plate.

[0011] Preferably, the adjacent grid blocks are connected through a connecting block, the connecting block comprises a sliding part and a locking part, the side of the adjacent grid blocks close to each other is provided with a sliding groove, and the sliding part of the connecting block slides in the sliding groove; when the adjacent grid blocks move in the direction away from each other, the locking part abuts against the groove opening of the sliding groove to prevent the adjacent grid blocks from separating.

[0012] By using the above technical scheme, when the grid plate rises, all the grid blocks are driven to be distributed in an inclined manner, and the adjacent grid blocks are separated under the action of the connecting block, thereby moving together with the grid plate; meanwhile, due to the separation of the grid blocks, there is a gap between the adjacent grid plates, that is, the flow area of the rainwater is increased.

[0013] Preferably, a filter screen for filtering leaves and other sundries is arranged in the underground pipe, and a sundry collecting pipe is arranged on the side of the filter screen close to the drain pipe and located below the underground pipe.

[0015] Preferably, a sundry removing pipe is communicated with the upper side of the underground pipe, the sundry removing pipe is located directly above the sundry collecting pipe, and a cover is overlapped with the pipe opening of the sundry removing pipe.

[0016] By using the above technical scheme, the cover is opened, and the leaves and other sundries in the sundry collecting pipe are regularly taken out by using an auxiliary tool, thereby preventing too many sundries from affecting the drainage effect.

[0017] Preferably, the filter screen is arranged in an inclined manner, and the filter screen is inclined downward along the direction away from the drain pipe.

[0018] By using the above technical scheme, when leaves and other sundries enter the underground pipe along with the rainwater, the leaves and other sundries may be hung on the filter screen; the filter screen is arranged in an inclined manner, on the one hand, the leaves and other sundries can fall into the sundry collecting pipe due to gravity, and on the other hand, when the rainwater and wastewater pass through the filter screen, a large impact force is generated on the filter screen, so that the filter screen vibrates, and the leaves and other sundries are more easily separated from the filter screen.

[0019] Preferably, a mounting plate is arranged horizontally in the drain pipe, a waterproof bin is arranged on the mounting plate, the driving cylinder is arranged in the waterproof bin, and a through hole is arranged at the top of the waterproof bin, and the driving cylinder rod passes through the through hole.

[0020] By adopting the above technical scheme, the driving cylinder rod is arranged in the waterproof bin, and the waterproof operation of the driving cylinder is achieved.

[0021] Preferably, the top of the waterproof bin abuts against the bottom side of the grid plate in the lowered state.

[0022] By adopting the above technical scheme, the top of the waterproof bin abuts against the bottom of the grid plate in the lowered state, and the grid plate is supported, which helps to improve the structural strength of the grid plate. In addition, when the grid plate is opened, rainwater flows into the drain pipe from the grid block, and the rainwater enters the drain pipe in a parabolic shape. The rainwater contacts the side wall of the waterproof bin, which helps to prevent rainwater from entering the waterproof bin from the through hole at the top of the waterproof bin, and further improves the waterproof effect of the driving cylinder.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. The driving cylinder drives the grid plate to rise, drives the grid block to rotate, and increases the gap between adjacent grid blocks, which helps to improve the drainage effect of the garden;

[0025] 2. The filter screen is arranged obliquely, and when leaves and other debris are hung on the filter screen, the filter screen will vibrate under the impact of rainwater, so that the leaves and other debris fall into the debris collecting pipe, improving the drainage effect;

[0026] 3. The top of the waterproof bin abuts against the bottom side of the grid plate in the lowered state, which helps to improve the structural strength of the grid plate. On the other hand, when the grid plate rises, the incoming rainwater will contact the side wall of the waterproof bin in a parabolic shape, which helps to prevent rainwater from entering the interior from the through hole of the waterproof bin, and improves the waterproof performance of the driving cylinder.

DETAILED DESCRIPTION

[0033] The following will be combined with the accompanying Figures 1-5 The application is further described in detail.

[0034] The embodiment of the application discloses a garden drainage device.

[0035] Reference Figure 1 and Figure 2 The garden drainage device comprises a vertically arranged drain pipe 1 and an underground pipe 2 communicated with a lower pipe opening of the drain pipe 1, wherein the drain pipe 1 and the underground pipe 2 are pre-buried underground, the upper pipe opening of the drain pipe 1 is flush with the ground, a sink 11 is formed at the upper pipe opening of the drain pipe 1, the drain pipe 1 is provided with a grid plate 3 in the sink 11, the drain pipe 1 is provided with a driving member 4 for driving the grid plate 3 to lift and fall, and the grid plate 3 is provided with a grid assembly 5 around the four sides for connecting the drain pipe 1 and the grid plate 3.

[0036] The structures and principles of the four grid assemblies 5 are the same, and one of the grid assemblies 5 will be taken as an example for description below.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The grid assembly 5 comprises a plurality of grid blocks 51, the adjacent grid blocks 51 are connected by connecting blocks 6 and realize sliding and telescopic cooperation, the grid block 51 far away from the grid plate 3 is hinged in the sink 11, and the grid block 51 close to the grid plate 3 is hinged with the grid plate 3. When the driving member 4 drives the grid plate 3 to rise, each grid block 51 will also rotate and be arranged in an inclined manner, meanwhile, the adjacent grid blocks 51 will be separated, and a flow-through gap is formed between the adjacent grid blocks 51, thereby increasing the flow-through area of rainwater. When the rainwater volume is large, the grid plate 3 is lifted to lift up the leaves and other impurities, and the leaves and other impurities at the side will slide down due to the inclination of the grid block 51, and then the rainwater can flow into the drain pipe 1 from the side grid block 51 and the flow-through gap, which is helpful to improve the drainage effect of the garden.

[0038] Reference Figure 3 and Figure 4The connecting block 6 comprises a sliding part 61 and a locking part 62 at both ends of the sliding part 61, and the locking part 62 is in the shape of a T-shaped block. Correspondingly, a sliding groove 7 is formed on the grid block 51 and is in sliding cooperation with the sliding part 61 of the connecting block 6. When the adjacent grid blocks 51 are separated, the locking part 62 is in abutment with the slot of the sliding groove 7 to limit the separation of the adjacent grid blocks 51. When the grid plate 3 rises, all the grid blocks 51 will move, and at this time, the adjacent grid blocks 51 will be separated under the action of the connecting block 6, thereby forming a flow gap, and the flow gap is also formed between the adjacent grid assemblies 5, thereby increasing the flow area of the rainwater and improving the drainage effect.

[0039] With reference to Figure 2 and Figure 5 , the installation plate 12 is installed in the drainage pipe 1 in the horizontal direction, and the waterproof bin 8 is installed on the installation plate 12. When the grid plate 3 is in the lowered state, the top of the waterproof bin 8 is in abutment with the grid plate 3, which helps to improve the structural strength of the grid plate 3. The driving member 4 is a driving cylinder 41, and the driving cylinder 41 is a waterproof cylinder. The driving cylinder 41 is fixedly installed in the waterproof bin 8. The top of the waterproof bin 8 is provided with a penetrating groove 81. The driving cylinder 41 is vertically upward. The piston rod of the driving cylinder 41 penetrates the penetrating groove 81. The end of the piston rod of the driving cylinder 41 is fixedly connected with the connecting plate 42, and the connecting plate 42 is fixedly connected with the grid plate 3. The waterproof bin 8 protects the driving cylinder 41. When the grid plate 3 is in the raised state, the rainwater will flow into the drainage pipe 1 from the grid block 51 and be in contact with the side wall of the waterproof bin 8 in the shape of a parabola. The waterproof bin 8 is thus arranged, which helps to avoid the rainwater from entering the waterproof bin 8 from the penetrating groove 81, thereby improving the waterproof performance of the driving cylinder 41.

[0040] With reference to Figure 2 , the filter screen 9 is installed in the underground pipe 2 and is arranged in an inclined manner. The filter screen 9 is inclined from top to bottom in a direction away from the drainage pipe 1. The underground pipe 2 is communicated with the sundry collecting pipe 10 on the side close to the drainage pipe 1. The sundry collecting pipe 10 is located below the underground pipe 2. The upper side of the underground pipe 2 is communicated with the sundry removing pipe 20. The sundry removing pipe 20 is located directly above the sundry collecting pipe 10. The upper end of the sundry removing pipe 20 is flush with the ground. The pipe opening of the sundry removing pipe 20 is overlapped with the cover 30.

[0041] The grid plate 3 plays a role in preliminarily filtering sundries such as leaves, but it is inevitable that some sundries will enter the underground pipe 2. The filter screen 9 is used to filter the sundries, and the sundries will fall into the sundry collecting pipe 10 in front of the filter screen 9. The cover 30 is opened, and the sundries are salvaged from the sundry removing pipe 20 at regular intervals, which helps to prevent the sundries from being accumulated too much and affecting the drainage effect. The filter screen 9 is arranged in an inclined manner. If the sundries are hung on the filter screen 9, the sundries will fall off due to their own gravity. When the rainwater impacts the filter screen 9, the filter screen 9 will vibrate, thereby making it easier for the sundries to fall off the filter screen 9.

[0042] The implementation principle of the garden drainage device is as follows: when the grid plate 3 is in a lowered state, the grid plate 3 and all the grid blocks 51 are flush with the ground, and normal drainage operation is achieved; if there are many leaves and other sundries on the surface of the grid plate 3 and the grid blocks 51, the drainage effect of the drainage system will be affected. At this time, the driving cylinder 41 drives the grid plate 3 to rise, lifting the sundries, and in addition, the grid blocks 51 will be inclined, at this time, the leaves and other sundries will slide off the grid blocks 51, and the grid blocks 51 will slide relative to each other, the gap between adjacent grid blocks 51 increases, and at the same time, a flow-through gap exists between adjacent grid assemblies 5, that is, the flow-through area of the rainwater is increased, which helps to improve the drainage effect of the drainage system.

[0043] The top of the waterproof bin 8 abuts against the bottom of the grid plate 3 in the lowered state, which helps to improve the structural strength of the grid plate 3, and when the grid plate 3 rises, the rainwater flows into the drainage pipe 1 in a parabolic shape, and since the top of the waterproof bin 8 is relatively high, it helps to prevent rainwater from entering the waterproof bin 8 through the through groove 81, that is, it helps to improve the waterproof effect on the driving cylinder 41.

[0044] The filter screen 9 is inclined, and the sundries will fall more easily into the sundry collecting pipe 10 due to their own gravity, and in addition, if the rainwater and wastewater impact the filter screen 9, it will cause the filter screen 9 to vibrate, and in turn, the sundries will fall more easily, that is, it helps to prevent the sundries from being hung on the filter screen 9, affecting the drainage effect.

[0045] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
