Description

Technical Field

[0001] The invention relates to the technical field of landscape gardening plant irrigation, in particular to an automatic water storage and sprinkler irrigation device for landscape gardening. Background Art

[0002] Landscape architecture is a natural environment and outdoor recreational space created by transforming the terrain or further building mountains, stacking water, and planting trees, flowers and plants.

[0003] A large number of plants are planted in landscape gardens, and they need to be watered regularly because water is an important component of plant cells, a medium for plant physiological activities, and has an important impact on plant temperature regulation and soil environment. However, due to the inconvenience of getting water in landscape gardens, when using natural precipitation to irrigate plants, although rainwater can make the surface planting layer of plants reach a water saturated state, the surface planting layer of plants at this time can no longer store excess rainwater, and it still cannot solve the problem of irrigation of plants in the absence of precipitation.

[0004] In order to make full use of rainwater and solve the problem of plant irrigation in the absence of precipitation, multiple water storage tanks for storing rainwater will be excavated in the park of landscape gardens, and then the water storage tanks will be connected to the sprinkler device set above the ground through pipelines for plant irrigation. However, since the top of the water storage tank is mostly open, in the rainless weather in summer, the dry weather will cause a large amount of water evaporation, which seriously affects the amount of rainwater stored in the water storage tank. When the evaporation is large, it may even cause the sprinkler device to fail to work normally, because it is necessary to cover the open top of the water storage tank with a cover plate to solve the problem of large amount of rainwater evaporation in the water storage tank, but this will also cause the water storage tank to need manual assistance to open and collect rainwater normally on rainy days, which will increase the labor cost. Although the electric control equipment can automatically open the cover plate on rainy days, the use of electricity on rainy days will not only increase the danger of electricity use on rainy days, but also a large number of electrical components will increase the cost. Therefore, it is of great significance to design an automatic water storage sprinkler device for landscape gardens that can automatically store water according to whether it rains. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic water storage and sprinkler irrigation device for landscape gardening, which realizes automatic opening of a cover plate to store water through a mechanical principle.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: It includes a water storage tank located underground and a cover plate covering the top opening of the water storage tank. It also includes a U-shaped water storage tank sealed by two U-shaped shells. Rainwater is stored in the cavity formed by the two U-shaped shells. One end of the U-shaped water storage tank has an open top, the other end of the U-shaped water storage tank has a sealed top, and a siphon tube is also provided on the open top of the U-shaped water storage tank; A connecting rod is connected to the cover plate, and the connecting rod is connected to a piston assembly for moving the connecting rod up and down. The piston assembly includes:

[0011] A spring, sleeved on the push-pull rod located inside the piston shell;

[0012] When the cover plate covers the top opening of the water storage tank, the piston abuts against the bottom of the piston shell and blocks the liquid inlet pipe to limit water from entering the piston shell.

[0013] Preferably, the open top of the U-shaped water storage tank is trumpet-shaped.

[0014] Preferably, it further includes a gear-driven up-and-down reciprocating assembly. The gear-driven up-and-down reciprocating assembly includes a gear driving part, a first toothed plate and a second toothed plate. The first toothed plate is vertically provided on the push-pull rod. A rigid drain pipe is also provided on the U-shaped water storage tank. A blocking member is provided on the drain pipe. The blocking member is used to change the cross-sectional area of the drain pipe to control the on-off of the drain pipe. The second toothed plate is vertically provided on the blocking member. The gear driving part can mesh with the first toothed plate and the second toothed plate.

[0015] Preferably, the blocking member includes a guiding cylinder body and a blocking block. The guiding cylinder body is provided on the drain pipe, and a jack is provided at the bottom end of the guiding cylinder body. The jack is communicated with the drain pipe. The top end of the blocking block is connected to a fixing rod, and the fixing rod is connected to the second toothed plate. The bottom end of the blocking block is inserted into the guiding cylinder body along the top end of the guiding cylinder body in the vertical direction and is in sealed sliding connection with the inner wall of the guiding cylinder body. And the blocking block can penetrate through the jack and enter the drain pipe and abut against the inner wall of the drain pipe.

[0016] Preferably, the plugging block is a circular plate, the diameter of the circular plate matches the inner diameter of the drain pipe, and a rubber ring is also provided on the circular plate.

[0017] Preferably, the gear driving part further includes a mounting frame and a toothed disc. The mounting frame is connected to the U-shaped water storage tank, the toothed disc is rotatably connected to the mounting frame, the first toothed plate is arranged on the push rod in the vertical direction, and both the second toothed plate and the first toothed plate are engaged with the toothed disc.

[0018] Preferably, the diameter of the siphon pipe is one-fifth to one-third of the inner diameter of the U-shaped water storage tank.

[0019] Preferably, the water storage tank is connected to a sprinkler device arranged above the ground through a pipeline.

[0020] Preferably, the drain pipe can also be connected to the sprinkler device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention realizes automatic opening of the cover plate for water storage through mechanical principles. When it does not rain, there may or may not be rainwater stored in the U-shaped water storage tank. If there is rainwater in the U-shaped water storage tank, the stored rainwater is not enough to push the piston away from the bottom of the piston housing, nor is it enough to make the piston housing communicate with the liquid inlet pipe; when it rains, rainwater will enter the U-shaped water storage tank through the top opening of the U-shaped water storage tank. As the amount of rainwater entering the U-shaped water storage tank increases, the water pressure in the U-shaped water storage tank also gradually increases. When the pressure of the rainwater is greater than the elastic force of the spring, the spring will be gradually compressed, and the water will enter through the liquid inlet pipe and push the piston to rise from the lowest end to the uppermost end. Since the rain continues to fall, the amount of rainwater stored in the U-shaped water storage tank will not change. Therefore, during the entire rainy period, the rising piston will push the push rod to drive the cover plate to rise, thus realizing the opening of the cover plate. When the rain stops, the water in the U-shaped water storage tank will also volatilize as the evaporation amount increases, and the volatilized water will change the pressure in the U-shaped water storage tank. Therefore, the spring will recover its elastic deformation, and the cover plate will block the water storage tank again when returning to the initial state. In addition, the design of the siphon pipe is such that when it rains, rainwater will enter the U-shaped water storage tank through the top opening of the U-shaped water storage tank, which will not affect the water level of the U-shaped water storage tank 4. When it does not rain, as the water level in the U-shaped water storage tank changes due to evaporation, the change in water pressure will cause the spring to recover its elastic deformation, thereby pushing the rainwater in the piston housing in the reverse direction. At the same time, the siphon pipe can also quickly discharge the rainwater sent in the reverse direction, so as to block the water storage tank with the cover plate again.

Detailed implementation manners

[0030] In order to make the above-mentioned objects, features, and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] The inventor found that the water storage tank in the landscape garden has a large evaporation loss when there is no rain and the problem that the cover plate needs to be manually opened to collect rainwater on rainy days. At the same time, considering the danger of using electricity on rainy days, an automatic water storage and sprinkler irrigation device based on mechanical principles is designed to automatically control the opening of the water storage tank according to whether it is raining, without electric drive, so as to achieve efficient water conservation and automated management.

[0032] Therefore, in order to solve the above-mentioned problems, the present invention provides an automatic water storage and sprinkler irrigation device for a landscape garden, which solves the problem of high labor cost caused by manually opening the cover plate and can automatically open the cover plate for water storage on rainy days.

[0033] Next, refer to Figures 1 to 5 Describe an automatic water storage and sprinkler irrigation device for a landscape garden according to an embodiment of the present invention.

[0034] Reference Figures 1 to 5 , the present invention provides an automatic water storage and sprinkler irrigation device for landscape gardening, including: a water storage tank 1 located underground and a cover plate 2 covering the top open end of the water storage tank 1. It also includes a U-shaped water storage tank 4 sealed by two U-shaped shells. Rainwater is stored in the cavity formed by the two U-shaped shells. One end of the U-shaped water storage tank 4 is open at the top, the other end of the U-shaped water storage tank 4 is sealed at the top, and a siphon tube 6 is also provided on the top open of the U-shaped water storage tank 4; a connecting rod is connected to the cover plate 2, and the connecting rod is connected to a piston assembly for moving the connecting rod up and down. The piston assembly includes: a piston unit 5, and the piston unit 5 is arranged on the top sealed end of the U-shaped water storage tank 4. The injection unit 5 includes: a piston housing 5.1, a piston 5.2 and a spring 5.3. Among them, a through hole is opened at the top of the piston housing 5.1, a liquid inlet pipe is provided at the bottom of the piston housing 5.1, and the liquid inlet pipe is communicated with the top sealed end of the U-shaped water storage tank 4, and the top of the piston housing 5.1 is flush with the top sealed end of the U-shaped water storage tank 4; the piston 5.2 is arranged in the piston housing 5.1, and the piston housing 5.1 and the U-shaped water storage tank 4 have the same diameter;

[0035] The push rod 5.3 extends into the piston housing 5.1 through the through hole. The push rod 5.3 located in the piston housing 5.1 is connected to the piston 5.2, and the push rod 5.3 located outside the piston housing 5.1 is connected to the cover plate 2 through a connecting piece;

[0036] The spring 5.3 is sleeved on the push rod 5.3 located in the piston housing 5.1. At this time, the elastic force of the spring 5.3 is used to keep the piston 5.2 in the initial state of abutting against the bottom end of the piston housing;

[0037] When the cover plate 2 covers the top open end of the water storage tank 1, the piston 5.2 abuts against the bottom of the piston housing 5.1 and blocks the liquid inlet pipe to limit the water from entering the piston housing 5.1.

[0038] When in use and it is not raining, there may or may not be rainwater stored in the U-shaped water storage tank 4. If there is rainwater in the U-shaped water storage tank 4, the stored rainwater is not sufficient to push the piston away from the bottom of the piston housing 5.1, nor is it sufficient to connect the piston housing 5.1 with the liquid inlet pipe; when it is raining, rainwater will enter the U-shaped water storage tank 4 through the top opening of the U-shaped water storage tank 4. As the amount of rainwater entering the U-shaped water storage tank 4 increases, the water pressure in the U-shaped water storage tank 4 also gradually increases. When the pressure of the rainwater is greater than the elastic force of the spring 5.3, the spring 5.3 will be gradually compressed, and the water will enter through the liquid inlet pipe and push the piston 5.2 to rise from the lowest end to the uppermost end. Since the rain continues to fall, the amount of rainwater stored in the U-shaped water storage tank 4 will not change. Therefore, during the entire rainy period, the rising piston 5.2 will push the push rod 5.3 to drive the cover plate 2 to rise, thus realizing the opening of the cover plate 2. When the rain stops, the water in the U-shaped water storage tank 4 will also volatilize as the evaporation amount increases. The volatilized water will change the pressure in the U-shaped water storage tank 4. Therefore, the spring 5.3 will recover its elastic deformation, and the cover plate 2 will seal the water storage tank 1 again in the initial state. When it is raining, rainwater will enter the U-shaped water storage tank 4 through the top opening of the U-shaped water storage tank 4. Even if a siphon 6 is connected to the top opening of the U-shaped water storage tank 4, it will not affect the water level in the U-shaped water storage tank 4. When it is not raining, as the water level in the U-shaped water storage tank 4 changes due to evaporation, not only will the spring 5.3 recover its elastic deformation, thus pushing the rainwater in the piston housing 5.1 out in the reverse direction, but also the siphon 6 can quickly drain the rainwater pushed out in the reverse direction. The diameter of the siphon 6 is much smaller than the diameter of the U-shaped water storage tank 4.

[0039] Specifically, the top opening of the U-shaped water storage tank 4 is trumpet-shaped. The purpose of this setting is to increase the evaporation surface, thereby further expanding the evaporation amount.

[0040] Specifically, in order to drain the rainwater in the U-shaped water storage tank 4 more quickly, the following structure is provided. It further includes a gear-driven up-and-down reciprocating assembly 9. The gear-driven up-and-down reciprocating assembly 9 includes a gear driving part, a first toothed plate 9.1 and a second toothed plate 9.2. The first toothed plate 9.1 is arranged vertically on the push rod 5.3. A rigid drain pipe 7 is also provided on the U-shaped water storage tank 4. A blocking member 8 is provided on the drain pipe 7. The blocking member 8 is used to change the cross-sectional area of the drain pipe 7 to control the on-off of the drain pipe 7. The second toothed plate 9.2 is arranged vertically on the blocking member 8. The gear driving part can be engaged with the first toothed plate 9.1 and the second toothed plate 9.2.

[0041] Specifically, the plugging member 8 includes a guiding cylinder body 8.1 and a plugging block 8.2. The guiding cylinder body 8.1 is arranged on the drain pipe 7, and a jack is provided at the bottom end of the guiding cylinder body 8.1. The jack is communicated with the drain pipe 7. The top end of the plugging block 8.2 is connected to a fixing rod, and the fixing rod is connected to the second tooth plate 9.2. The bottom end of the plugging block 8.2 is inserted into the guiding cylinder body 8.1 along the top end of the guiding cylinder body 8.1 in the vertical direction and is in sealed sliding connection with the inner wall of the guiding cylinder body 8.1. Moreover, the plugging block 8.2 can penetrate through the jack and enter the drain pipe 7 and abut against the inner wall of the drain pipe 7.

[0042] Specifically, the plugging block 8.2 is a circular plate. The diameter of the circular plate matches the inner diameter of the drain pipe 7, and a rubber ring is also provided on the circular plate.

[0043] Specifically, the gear driving part further includes a mounting frame and a toothed disc 9.3. The mounting frame is connected to the U-shaped water storage tank 4, the toothed disc 9.3 is rotatably connected to the mounting frame, the first tooth plate 9.1 is arranged on the push-pull rod 5.3 in the vertical direction, and both the second tooth plate 9.2 and the first tooth plate 9.1 are meshed with the toothed disc 9.3.

[0044] Specifically, the pipe diameter of the siphon 6 is one-fifth to one-third of the inner diameter of the U-shaped water storage tank 4. The siphon 6 with this size can help to quickly drain the rainwater in the U-shaped water storage tank 4.

[0045] Specifically, the water storage tank 1 is connected to a sprinkler device 3 arranged above the ground through a pipeline. A submersible pump is provided at the water inlet end of the pipeline located in the water storage tank 1.

[0046] Specifically, the drain pipe 7 can also be connected to the sprinkler device 3, which can not only drain the water in the U-shaped water storage tank 4, but also recycle the drained water.
