Description

Technical Field

[0001] The utility model relates to the technical field of planting boxes, in particular to an automatic irrigation device and a water storage system suitable for planting boxes and similar devices. Background Art

[0002] The structure of similar devices such as planting boxes mainly consists of two parts, the upper area is the plant planting area, and the lower area is the water storage area, which are separated by a partition. The water in the lower area can be achieved by injecting water from the upper area downward (for example: irrigation) or injecting water into the lower area through a special water injection pipe. The water is collected and stored in the water storage tank at the bottom through sedimentation. Over time, in the absence of water injection, the water in the water storage tank returns to the soil to replenish water for the plants through the columnar body or cotton thread with fine grooves at the bottom of the water storage tank through the siphon principle. A buoy indicator is connected to the bottom of the water storage tank to display the water level and prompt timely watering.

[0003] However, existing planting box structures can achieve water addition operations well, but cannot reduce the amount of water. Even if it can reduce the amount of water, the operation is more complicated and often requires manual operation. Therefore, if there is too much water in the water tank due to weather (for example, it is placed outdoors in a rainstorm) or other factors (for example, excessive water addition due to improper operation or miscalculation), the plants may become waterlogged and their roots may rot.

[0004] Therefore, there is a need to improve this type of structure. Utility Model Content

[0005] The purpose of the utility model is to improve the existing technology and provide an automatic irrigation water storage device, which has the functions of observing water volume, filling and replenishing water, and automatically overflowing excess water, and has a simple structure and is easy to clean.

[0006] The purpose of the utility model is achieved in this way:

[0007] An automatic irrigation water storage device comprises: a water storage box, an upper cover and a bent pipe; the water storage box is a box body with an open top surface, a connecting pipe is arranged on the side wall of the water storage box near the bottom surface, and the connecting pipe has an inner opening opened on the inner wall of the water storage box and an outer opening opened on the outer wall of the water storage box. The upper cover has a flat plate-shaped cover body, and the upper cover is provided with a plurality of planting grooves, which extend downward from the upper surface of the upper cover to form a columnar cavity, and the lower part of the columnar cavity is provided with a slot, and the upper cover covers the opening of the water storage box so that the planting grooves are located in the water storage box; the bent pipe has a horizontal section and a vertical section that are connected to each other, the horizontal section is connected to the outer opening of the connecting pipe, the vertical section is connected to the connecting pipe through the horizontal section and the opening of the vertical section faces upward, the vertical section is a translucent or transparent pipe, and the length of the vertical section is set so that when the opening of the vertical section faces upward, the height of the opening is flush with or slightly lower than the plane where the opening of the water storage box is located.

[0008] Due to the effect of atmospheric pressure, the water level in the vertical section should be consistent with the water level in the water storage box. The vertical section is translucent or transparent, so its water level can be directly observed, thereby determining the water level in the water storage box. If the water level is low and more water needs to be added, it can be directly filled in from the opening of the vertical section. Since the height of the vertical section is designed to be flush with or slightly lower than the plane where the opening of the water storage box is located, when there is too much water in the water storage box, the excess water can directly overflow from the opening of the vertical section.

[0009] The automatic irrigation water storage device proposed by the utility model adopts the above-mentioned technical solution, thereby combining the water filling pipe and the indicator into one, and can instantly display the water level in the box without installing a buoy, so that the indication function can be better realized while the structure is simpler; the pipe mouth is both a water filling port and an overflow port, and can display the water level, which is easy to operate and can reduce costs; compared with the existing structure, the utility model has a simple structure and is easy to clean.

[0010] Preferably, the horizontal section of the elbow can be rotatably connected to the outer opening of the connecting pipe through a connecting short pipe, so that the elbow can be rotated from state 1 with the opening of the vertical section facing upward to state 2 with the opening of the vertical section facing downward. In this way, when rapid drainage is required, the elbow can be directly rotated to state 2, i.e., the opening of the vertical section faces downward.

[0011] Wherein, the connecting short tube can be an elastic hose, one end of which is sleeved on the end of the horizontal section, and the other end is sleeved on the outer opening of the connecting tube. In the normal state, the elbow is in state one, that is, the opening of the vertical section faces upward; when it is necessary to adjust to state two briefly, since the connecting short tube is an elastic hose, it can achieve torsional deformation within a certain range. The operator can adjust the elbow to state two by directly twisting the connecting short tube 180° and holding it by hand, and restore it to state one by directly letting go after the operation is completed; when it is necessary to keep the elbow in state two for a period of time, it can also be directly rotated 180° at the interface to adjust the elbow to state two. When the interface is rotated, since the connecting short tube is an elastic hose, a pressure can be applied to the operation point during the rotation operation to prevent it from falling off or leaking.

[0012] Alternatively, the connecting short pipe may also be a hard pipe, which is connected to the horizontal section of the curved pipe through a rotatable threaded interface at the end of the hard pipe, and the conversion between state one and state two may also be achieved.

[0013] In order to facilitate opening the water storage box and the upper cover, preferably, the water storage box has a top edge, which is a narrow surface extending outward around the edge of the opening; the upper cover has a cover edge, which is a portion located around the edge of the upper cover, and the cover edge fits with the top edge; the upper cover is detachably fixed to the top surface of the water storage box by snapping the cover edge onto the top edge. In addition, such a structure with a top edge and a cover edge that fit together can also provide convenience for transportation.

[0014] Preferably, an upwardly protruding reinforcing rib is provided on the upper surface of the top edge, and the reinforcing rib is arranged on the upper surface of the top edge so as to extend from the inside of the water storage box to the outside. When the cover edge is buckled on the top edge, a plurality of overflow grooves extending inward and outward are formed between the cover edge and the top edge through the reinforcing rib. When there is too much water in the water storage box but it is not discovered in time (for example, in case of a nighttime rainstorm), resulting in the excess water not having time to overflow from the opening of the vertical section, the overflow groove can speed up the discharge of the excess water, thereby avoiding the device being in a state of being overfilled for a long time and preventing the plants from being soaked in water and having their roots rotten.

[0015] Furthermore, the automatic irrigation water storage device may also be provided with a water inlet pipe, which is connected to the vertical section of the curved pipe and is used to add water to the water storage box. Preferably, the automatic irrigation water storage device may also be provided with a timing device, which is provided at the water inlet pipe and is used to control the timing of adding water to the water storage box.

[0016] Furthermore, a connecting pipe can be provided on other side walls of the automatic irrigation water storage device near the bottom surface, and a plug can be provided for the connecting pipe so that the connecting pipe can be opened or closed by the plug according to usage requirements, and water can be inlet or outlet from different connecting pipes according to actual application scenarios.

[0017] Furthermore, the automatic irrigation water storage device provided with two or more connecting pipes can also be connected through connecting pipes to form a combined structure. Based on this idea, the utility model also provides an automatic irrigation water storage system, which includes a plurality of water storage device units, at least one bent pipe, a plurality of connecting pipes and a plurality of plugs. Each of the water storage device units includes: a water storage box and an upper cover; the water storage box is a box body with an open top surface, and at least two connecting pipes are provided on the side wall of the water storage box near the bottom surface, and the connecting pipe has an inner opening opened on the inner wall of the water storage box and an outer opening opened on the outer wall of the water storage box; the upper cover has a flat plate-shaped cover body, and the upper cover is provided with a plurality of planting grooves, and the planting grooves extend downward from the upper surface of the upper cover to form a columnar cavity, and the lower part of the columnar cavity is provided with a slot, and the upper cover covers the opening of the water storage box so that the planting grooves are located in the water storage box. The bent pipes all have a connected horizontal section and a vertical section, the horizontal section is connected to the outer opening of the connecting pipe, the vertical section is connected to the connecting pipe through the horizontal section and the opening of the vertical section faces upward, the vertical section is a translucent or transparent pipe, and the length of the vertical section is set so that when the opening of the vertical section faces upward, the height of the opening is flush with or slightly lower than the plane where the opening of the water storage box is located.

[0018] The connecting pipe is used to connect the water storage device monomers together, one end of the connecting pipe is connected to the outer opening of a connecting pipe of one water storage device monomer, and the other end is connected to the outer opening of a connecting pipe of another water storage device monomer, so that the water storage boxes of the water storage device monomers are directly or indirectly connected through the connecting pipe. The plug is used to close the inner opening and / or outer opening of the connecting pipe, and the number of the plugs matches the number of the connecting pipes. The number of the plugs can be configured as the same number or twice the number of the connecting pipes as needed. Generally speaking, when configuring the number of plugs, at least one less than the number of connecting pipes should be configured, so that each connecting pipe except the connecting pipe connected to the elbow can be closed by the plug.

[0019] The automatic irrigation water storage system proposed by the utility model adopts the above-mentioned technical solution, thereby combining the water filling pipe and the indicator into one, and can instantly display the water level in the box without installing a buoy, which can better realize the indication function while having a simpler structure; the pipe mouth is both a water filling port and an overflow port, and can also display the water level, which is easy to operate and can reduce costs.

[0020] Preferably, the horizontal section of the elbow can be rotatably connected to the outer opening of the connecting pipe through a connecting short pipe, so that the elbow can be rotated from state 1 with the opening of the vertical section facing upward to state 2 with the opening of the vertical section facing downward. In this way, when rapid drainage is required, the elbow can be directly rotated to state 2, i.e., the opening of the vertical section faces downward.

[0021] Wherein, the connecting short tube can be an elastic hose, one end of which is sleeved on the end of the horizontal section, and the other end is sleeved on the outer opening of the connecting tube. In the normal state, the elbow is in state one, that is, the opening of the vertical section faces upward; when it is necessary to adjust to state two briefly, since the connecting short tube is an elastic hose, it can achieve torsional deformation within a certain range. The operator can adjust the elbow to state two by directly twisting the connecting short tube 180° and holding it by hand, and restore it to state one by directly letting go after the operation is completed; when it is necessary to keep the elbow in state two for a period of time, it can also be directly rotated 180° at the interface to adjust the elbow to state two. When the interface is rotated, since the connecting short tube is an elastic hose, a pressure can be applied to the operation point during the rotation operation to prevent it from falling off or leaking.

[0022] Alternatively, the connecting short pipe may also be a hard pipe, which is connected to the horizontal section of the curved pipe through a rotatable threaded interface at the end of the hard pipe, and the conversion between state one and state two may also be achieved.
