Description

Technical Field

[0001] The invention relates to the technical field of sponge city construction, in particular to a sponge ecological rainwater landscape pressure equipment. Background Art

[0002] Sponge ecological city means that the city can adapt to environmental changes and respond to natural disasters like a sponge, absorbing water, storing water, infiltrating water, and purifying water when it rains, and "releasing" and utilizing the stored water when needed, gradually improving and restoring the natural ecological balance of the city. In the process of sponge city construction, people and natural ecology should be given priority, so it is defined as an ecological sponge city.

[0003] The sponge ecological concept was first proposed and applied in garden landscapes, mainly to collect and store rainwater on rainy days and to water landscape vegetation in the dry season or when water replenishment is needed, so as to make full use of water resources.

[0004] The traditional concept of rainwater utilization is to collect rainwater and use it at the right time. However, in the field of landscape, people are not easily aware of the problem that most vegetation does not need to be watered during the spring, autumn and winter rainy seasons. Frequent watering is only required in the hot summer. It is conceivable that the reason is not due to vegetation absorption, but the high temperature and rapid evaporation of rainwater. Both the moisture in the soil and the collected rainwater will evaporate at a very fast rate. This is the main reason for the large water demand for vegetation planting. The existing sponge ecological rainwater landscape pressure equipment cannot collect the collected rainwater for a second time. Most of the collected rainwater will evaporate in the hot summer instead of being absorbed by the vegetation. In addition, it is generally used in the form of timed automatic pump irrigation. In the period of abundant rainwater, there is a conflict between automatic timed irrigation and rainwater, resulting in limited resource utilization.

[0005] In addition, for landscape vegetation, the vegetation on the same landscape flower cone-shaped growth base needs to grow synchronously to ensure consistency, so that more reasonable and beautiful vegetation can be grown according to the shape of the growth base. However, for traditional growth bases, an average spray water replenishment method is adopted. The water replenishment amount of the upper and lower parts is the same, but the landscape flowers planted in the upper and lower parts are pyramid-shaped. The landscape flowers are denser as they go down, and the water replenishment amount of the upper and lower parts is the same. The less water is allocated to each landscape flower as it goes down, resulting in asynchronous growth and smaller flowers as they become denser and denser. Although it meets the construction requirements of sponge ecology, there is still room for improvement in the consistency and aesthetics of landscape vegetation growth.

[0006] In view of the above problems, it is urgently necessary to carry out innovative design based on the original sponge ecological rainwater landscape pressure equipment. Summary of the invention

[0007] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the purpose of the present invention is to provide a sponge ecological rainwater landscape pressure device to solve the problem proposed in the above background technology that most vegetation does not need to be watered during the period of sufficient rainfall in spring, autumn and winter. Only in the hot summer, frequent watering is required. It can be imagined that the reason is not caused by vegetation absorption, but by the high temperature and fast evaporation of rainwater. Both the moisture in the soil and the collected rainwater will evaporate at a very fast rate. This is the main reason for the large water demand for vegetation planting. The existing sponge ecological rainwater landscape pressure equipment cannot collect the collected rainwater for a second time. Most of the collected rainwater will evaporate in the hot summer instead of being absorbed by the vegetation. In addition, it is generally used in the form of timed automatic pump irrigation. During the period of abundant rainfall, there is a conflict between automatic timed irrigation and rainwater, resulting in the problem of limited resource utilization.

[0009] Preferably, a plurality of elastic gaskets are evenly arranged between the conical landscape flower bed and the inner cone, and a latch is vertically fixed to the inner wall of the conical landscape flower bed, and the lower end of the latch is inserted and matched in a hole groove matched inside the inner cone.

[0010] Preferably, the magnetic staggered opening and closing assembly includes a hose, a metal pipe, a water injection port, an upper magnet and a lower magnet, and a hose is installed through the side of the secondary collection tank, and the outer end of the hose is connected to the metal pipe, the interior of the conical landscape flower bed and the annular cultivation tank are provided with water injection ports one by one, and the end of the metal pipe is located inside the water injection port, the lower end of the water injection port is connected to the annular cultivation tank, and the upper magnet and the lower magnet are respectively fixed to the upper and lower surfaces of the water injection port.

[0011] Preferably, the upper magnet and the lower magnet exert gravitational force on the metal tube, and the volume of the water collection tank inside the secondary collection tank gradually increases from top to bottom.

[0012] Preferably, the liquid level drop one-way detection trigger mechanism includes a turntable, a ring, a pin, a support rod, a lifting plate, a float, a belt, a driven shaft, a convex plate, a touch pressure sensor and a controller, and the inside of the rainwater collecting bin is respectively hinged with a turntable and a ring, and the turntable is sleeved at the center of the ring, the outer wall of the turntable is hinged with a pin, and the outer end of the pin is fitted to the inner wall of the ring, a support rod is fixed to the lower surface of the rainwater collecting bin, and the outer wall of the support rod is slidingly sleeved with a lifting plate, and the lifting plate is meshingly connected to the ring, a float is fixed to the upper end of the lifting plate, and the central axis of the turntable passes through the rainwater collecting bin through a bearing, one end of the belt is sleeved with the rainwater collecting bin, and the other end of the belt is provided with a driven shaft installed on the side wall of the rainwater collecting bin, the outer wall of the driven shaft end is fixed with a convex plate, and the side walls of the rainwater collecting bin are respectively fixed with a touch pressure sensor and a controller, and the touch pressure sensor and the condensation plate are both electrically connected to the controller.

[0013] Preferably, one end of a return spring is welded to the outer wall of the pin, and the other end of the return spring is fixed to the outer wall of the turntable, the inner wall of the ring is provided with one-way limit grooves at equal angles, and the outer end of the pin is engaged in the interior of a one-way limit groove.

[0014] Preferably, the touch pressure sensor has an arc-shaped touch pressure surface, and the arc center of the arc-shaped touch pressure sensor coincides with the axis center of the driven shaft, and the center distance of the convex plate is equal to the arc center distance of the arc-shaped touch pressure sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] When the rainwater collected in the rainwater collection bin gradually evaporates, most of the rainwater in the cultivation tank of the conical landscape flower bed will also evaporate and part of it will be consumed by the cultivated flowers, making the conical landscape flower bed lighter as a whole. When the weight of the conical landscape flower bed changes to a certain extent, multiple groups of evenly distributed elastic gaskets will reset and lift the conical landscape flower bed vertically upward, so that the distance between the conical landscape flower bed and the inner cone will gradually increase, making the conical landscape flower bed lighter. Figure 2 Convert to Figure 3 and Figure 4 When the distance between the conical flower bed and the inner cone gradually increases to a certain extent, that is, the conical flower bed rises vertically a certain distance (only a little bit is needed), Figure 2 and Figure 3 Originally, the metal pipe was adsorbed on the lower surface of the upper magnet and was in an upward and water-blocking posture. When the conical landscape flower bed rose vertically for a certain distance, the gravitational force of the lower magnet on the metal pipe gradually increased, and the metal pipe's own gravity finally Figure 5The metal tube shown will be adsorbed on the upper surface of the lower magnet and change from an upward water-blocking posture to a downward water-blocking posture, so that the water in the multi-stage water storage tank in the secondary collection tank enters the cultivation tank of the corresponding conical landscape flower bed through the corresponding hose and metal tube combination, thereby achieving the effect of automatic and efficient water replenishment. At the same time, the volume of the multi-stage water storage tank inside the secondary collection tank increases from top to bottom. That is to say, there is a distinction when replenishing water in the pyramid-shaped cultivation tank where the vegetation gradually increases from top to bottom. The more and denser the vegetation is, the more corresponding water replenishment is, thereby achieving the effect of averaging the amount of water replenished in the vegetation in the cultivation tank, thereby ensuring the consistency of vegetation growth in the cultivation tank.

[0017] Finally, when the water replenishment is completed, the weight inside the conical landscape flower bed will be restored and it will fall down again to compress the elastic gasket and the return spring again. Similarly, the metal tube will be sucked up by the upper magnet to reach an upward water-blocking state, and this cycle will be repeated. Pressure detection and pressure triggering can be used to achieve automatic water replenishment, and evaporated rainwater can be collected for a second time, avoiding the problem of insufficient water resource utilization caused by storing rainwater evaporation. At the same time, it can evenly distribute the water needed by vegetation, avoiding the problem caused by inconsistent vegetation growth at the upper and lower ends of the conical landscape flower bed.

[0030] The upper magnet 71 and the lower magnet 72 both exert gravitational force on the metal tube 24, and the volume of the water collection tank inside the secondary collection tank 21 gradually increases from top to bottom.

[0031] The liquid level drop one-way detection trigger mechanism includes a turntable 31, a collar 32, a latch 33, a support rod 35, a lifting plate 36, a float 37, a belt 38, a driven shaft 39, a convex plate 310, a touch pressure sensor 311 and a controller 312, and the inside of the rainwater collection bin 3 is respectively hinged with the turntable 31 and the collar 32, and the turntable 31 is sleeved at the center of the collar 32, the outer wall of the turntable 31 is hinged with the latch 33, and the outer end of the latch 33 is attached to the inner wall of the collar 32, and the support rod 35 is fixed to the lower surface of the rainwater collection bin 3, and the outer wall of the support rod 35 is slidably sleeved. A lifting plate 36 is provided, and the lifting plate 36 is meshingly connected to the ring 32, a float 37 is fixed to the upper end of the lifting plate 36, and the central axis of the turntable 31 passes through the rainwater collecting bin 3 through a bearing and is sleeved with one end of a belt 38, and the other end of the belt 38 is internally provided with a driven shaft 39 installed on the side wall of the rainwater collecting bin 3, a convex plate 310 is fixed to the outer wall of the end of the driven shaft 39, and a touch pressure sensor 311 and a controller 312 are respectively fixed to the side walls of the rainwater collecting bin 3, and the touch pressure sensor 311 and the condensation plate 6 are electrically connected to the controller 312.

[0032] One end of a return spring 34 is welded to the outer wall of the bayonet 33, and the other end of the return spring 34 is fixed to the outer wall of the turntable 31. The inner wall of the collar 32 is provided with one-way limit grooves at equal angles, and the outer end of the bayonet 33 is engaged in the inside of a one-way limit groove.

[0033] The pressure sensor 311 has an arc-shaped surface, and the arc center of the pressure sensor 311 coincides with the axis of the driven shaft 39 . The center distance of the convex plate 310 is equal to the arc center distance of the pressure sensor 311 .

[0034] Working principle: When using the sponge ecological rainwater landscape pressure equipment, first, on rainy days, rainwater fully falls into the cultivation trough of the conical landscape flower bed 1 and the water-collecting top plate 4, so that the cultivation trough in the conical landscape flower bed 1 is filled with water. At the same time, the rainwater gathered at the center of the water-collecting top plate 4 will enter the rainwater collection bin 3 through the water inlet channel 5 for storage.

[0035] When the rainy day ends, after being baked by the high temperature of summer, the rainwater collected in the rainwater collection bin 3 gradually evaporates and dissipates through the gaps between the devices, causing the liquid level to gradually drop. When the liquid level in the rainwater collection bin 3 gradually drops, the float 37 will also fall together under the action of its own gravity and drive the lifting plate 36 to fall vertically. Figure 6 and Figure 7 As shown, when the lifting plate 36 falls vertically, the tooth block on the side of the lifting plate 36 drives the ring 32 to rotate counterclockwise adaptively, and when the ring 32 rotates counterclockwise, it synchronously drives the turntable 31 to rotate counterclockwise adaptively through the latch 33, and when the turntable 31 rotates counterclockwise, it synchronously drives the convex plate 310 to rotate counterclockwise through the belt 38 and the driven shaft 39, so that the convex plate 310 gradually rotates and contacts the arc-shaped touch pressure area on the upper surface of the touch pressure sensor 311, and after receiving the touch pressure signal, the touch pressure sensor 311 immediately starts the condensation plate 6 through the controller 312, so that the temperature of the lower surface of the metal condensation plate 6 gradually decreases. At this time, the water vapor that evaporates inside the rainwater collection bin 3 and emits upward will quickly form water droplets on the lower surface of the condensation plate 6 after contacting the lower surface of the condensation plate 6 with a lower temperature. The water droplets finally formed will gradually flow invertedly along the inclined direction of the lower surface of the condensation plate 6 to the secondary collection liquid tank 21 at the edge for collection. The secondary collection liquid tank 21 is a setting similar to the shape of a conical landscape flower bed 1. When the water storage tank on the highest layer is full of water, the water will flow smoothly to the second layer, and so on to eventually fill up all the water tanks. At the same time, the condensation plate 6 can even collect and condense water vapor in the nearby air to achieve the effect of secondary water collection.

[0036] When the rainwater collected in the rainwater collection bin 3 gradually evaporates, most of the rainwater in the cultivation tank of the conical landscape flower bed 1 will also evaporate and part of it will be consumed by the cultivated flowers, making the conical landscape flower bed 1 lighter as a whole. When the weight of the conical landscape flower bed 1 changes to a certain extent, multiple groups of evenly distributed elastic gaskets 22 will reset to lift the conical landscape flower bed 1 vertically upward, so that the distance between the conical landscape flower bed 1 and the inner cone 2 will gradually increase, so that the conical landscape flower bed 1 and the inner cone 2 will gradually increase. Figure 2 Convert to Figure 3 and Figure 4 When the distance between the conical landscape flower bed 1 and the inner cone 2 gradually increases to a certain extent, that is, the conical landscape flower bed 1 rises vertically a certain distance (only a little rise is needed), the contrast Figure 2 and Figure 3 Originally, the metal tube 24 is adsorbed on the lower surface of the upper magnet 71 and is in an upward water-blocking posture. When the conical landscape flower bed 1 rises vertically for a certain distance, the attraction of the lower magnet 72 on the metal tube 24 gradually increases, and the metal tube 24 is finally lifted by its own gravity. Figure 5The metal tube 24 shown will be adsorbed on the upper surface of the lower magnet 72, and change from an upward water-blocking posture to a downward water-blocking posture, so that the water in the multi-stage water storage tank in the secondary collection tank 21 enters the cultivation tank of the corresponding conical landscape flower bed 1 through the corresponding hose 23 and metal tube 24 combination, thereby achieving the effect of automatic and efficient water replenishment. At the same time, the volume of the multi-stage water storage tank inside the secondary collection tank 21 increases from top to bottom. That is to say, there is a distinction when replenishing water in the pyramid-shaped cultivation tank where the vegetation gradually increases from top to bottom. The more and denser the vegetation is, the more corresponding water replenishment is, thereby achieving the effect of averaging the amount of water replenished in the vegetation in the cultivation tank, thereby ensuring the consistency of vegetation growth in the cultivation tank.

[0037] Finally, when the water replenishment is completed, the internal weight of the conical landscape flower bed 1 is restored and it will fall again to compress the elastic gasket 22 and the return spring again. Similarly, the metal tube 24 is sucked up by the upper magnet 71 to reach an upward water-blocking state. This cycle is repeated, and automatic water replenishment is achieved by using pressure detection and pressure triggering. The evaporated rainwater can be collected for a second time, avoiding the problem of insufficient water resource utilization caused by the evaporation of stored rainwater. At the same time, the water required by the vegetation can be evenly distributed, avoiding the problem caused by inconsistent vegetation growth at the upper and lower ends of the conical landscape flower bed 1.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
