Description

Technical Field

[0001] The present application relates to the field of housing construction technology, and in particular to an energy-saving building roof. Background Art

[0002] Building energy conservation refers to reducing energy consumption as much as possible while meeting the same needs or achieving the same purpose during the production of building materials, construction and use of houses and structures.

[0003] Energy-saving roofs mainly include thermal insulation roofs, flat roofs to slope roofs, ventilated roofs, planted roofs (green roofs), water storage roofs, etc.; among them, planted roofs are a more common method, which can effectively increase the green area and save land and resources.

[0004] In related technologies, a water tank is generally set up on the roof of a plantation. Rainwater is stored in the water tank when it rains, and the rainwater in the water tank is taken out to water the plants when there is a water shortage. However, since the amount of water used to water the plants each time is limited, in order to ensure that the soil of the plants has sufficient moisture, the plants need to be watered frequently. Utility Model Content

[0005] In order to receive more rainwater, the present application provides an energy-saving building roof.

[0006] This application provides an energy-saving building roof, which adopts the following technical solutions:

[0007] An energy-saving building roof comprises a building body and a water collection assembly disposed on the building roof, the water collection assembly comprising a water holding frame disposed around the building roof, a water reservoir located in the center of the building roof, and a plurality of connected planting water troughs, the water holding frame and the water reservoir being connected via a water pipe, and at least one of the planting water troughs being connected to the water holding frame;

[0008] The planting water tank is provided with a planting unit covering its notch, and the planting unit includes a basin body for accommodating green plants and a water-absorbing sponge arranged at the bottom of the basin body. The bottom of the basin body has an exchange port for allowing water vapor from the water-absorbing sponge to enter the basin body.

[0009] By adopting the above technical solution, when it rains, the water frame can hold and collect rainwater, and the rainwater in the water frame flows into the reservoir through the water pipe. In addition, the rainwater in the water frame will also flow into the planting trough, and the absorbent sponge will absorb the water in the planting trough. When the soil in the pot is short of water, the water in the absorbent sponge will seep into the pot through the exchange port, thereby providing water for the green plants in the pot; when the plants in the planting unit are short of water, the water in the reservoir can not only be poured into the planting unit, but also into the planting trough. The planting trough serves as a backup water resource for the planting unit. The planting unit only needs to be replenished with water after the water in the planting trough is used up. This expands the water storage capacity of the planting unit and reduces the frequency of watering the green plants. In addition, when the precipitation is heavy, the water in the pot can also flow out through the exchange port, making it difficult for the plants in the pot to be soaked by water.

[0010] Optionally, the planting water tank has steps for placing the basin body on the groove.

[0011] By adopting the above technical solution, the basin body can be erected on the steps, which not only stabilizes the planting unit in the planting water tank, but also prevents the basin body from squeezing the water-absorbing sponge, so that the water-absorbing sponge always remains relaxed and able to absorb water.

[0012] Optionally, the planting unit further comprises a plurality of connecting rods for fixing the water-absorbing sponge to the pot body, wherein the connecting rods penetrate into the water-absorbing sponge from the bottom of the water-absorbing sponge, and the ends of the connecting rods are inserted into the pot body.

[0013] By adopting the above technical solution, the water-absorbing sponge is connected to the bottom of the basin body through the connecting rod; and the connecting rod can also provide support for the water-absorbing sponge, so that the water-absorbing sponge is not easily squeezed or compressed.

[0014] Optionally, the connecting rod is fixedly connected to a limiting piece that abuts against the water-absorbing sponge.

[0015] By adopting the above technical solution, when the connecting rod penetrates the water-absorbing sponge and is screwed into the basin body, the limiting plate abuts against the water-absorbing sponge, and the water-absorbing sponge is supported by the limiting plate, making the water-absorbing sponge more stable and not easy to slip off the connecting rod.

[0016] Optionally, the limiting piece is spaced a distance from the end of the connecting rod away from the basin body.

[0017] By adopting the above technical solution, when the planting unit is placed in the planting water tank, the lower end of the connecting rod abuts against the bottom of the planting water tank, so that the water-absorbing sponge always maintains a distance from the bottom of the planting water tank, thereby allowing the water in the planting water tank to flow.

[0018] Optionally, the planting water tank is provided with an overflow outlet connected to the water reservoir.

[0019] By adopting the above technical solution, when the water level reaches a certain height, the water in the planting tank flows into the reservoir through the overflow port, so that the water in the planting tank is not easy to submerge the planting unit.

[0020] Optionally, the water holding frame includes a bottom plate, an inner plate and an outer plate, and the inner plate and the outer plate are both connected to the bottom plate to form a water holding tank with an upward opening.

[0021] By adopting the above technical solution, on sunny days, the water holding frame can also serve as a fence of the roof, making it difficult for people to walk to the edge of the roof; when it rains, the water holding frame can hold and collect rainwater.

[0022] Optionally, the water holding frame further includes a filter plate having filter holes, the filter plate is connected to the bottom plate, and a filter cavity is formed between the filter plate and the bottom plate.

[0023] By adopting the above technical solution, the filter plate can block some impurities, making the water in the water holding frame cleaner when entering the water reservoir.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The rainwater in the water frame will also flow into the planting water tank, and the water-absorbing sponge will absorb the water in the planting water tank. When the soil in the pot is short of water, the water in the water-absorbing sponge will seep into the pot through the exchange port, thereby providing water for the green plants in the pot;

[0026] 2. When the plants in a planting unit are short of water, the water in the reservoir can not only be poured into the planting unit, but also into the planting tank. The planting tank serves as a backup water resource for the planting unit. The planting unit only needs to be replenished with water after the water in the planting tank is used up. This expands the water storage capacity of the planting unit and reduces the frequency of watering the green plants.

[0027] 3. When the planting unit is placed in the planting tank, the lower end of the connecting rod abuts against the bottom of the planting tank, so that the water-absorbing sponge always maintains a distance from the bottom of the planting tank, thereby allowing the water in the planting tank to flow.

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] The embodiment of the present application discloses an energy-saving building roof.

[0039] Reference Figure 1 The energy-saving building roof includes a building body 1 and a water collection component 2. The top of the building body 1 is a roof, and green plants are planted on the roof; the water collection component 2 is arranged on the roof of the top of the building body 1, and rainwater is collected by the water collection component 2 for watering the green plants.

[0040] See also Figure 1 and Figure 2 Specifically, the water collection assembly 2 includes a water frame 21, a water reservoir 22, and several planting water troughs 23. The water reservoir 22 is located at the center of the roof of the building 1, and the water frame 21 is arranged around the roof of the building 1. The water frame 21 is connected to the water reservoir 22 through water pipes. When it rains, rainwater falls into the water frame 21 and then flows into the water reservoir 22 through the water pipes. When there is a water shortage, the water in the water reservoir 22 can be used to irrigate the green plants.

[0041] See also Figure 3 and Figure 4The water frame 21 includes a bottom plate 211, an inner panel 212, and an outer panel 213. The inner panel 212 and the outer panel 213 are connected to the bottom plate 211 to form an upward-opening water trough 214. On sunny days, the water frame 21 can also serve as a fence on the roof, preventing people from walking to the edge of the roof. When it rains, the water frame 21 can hold and collect rainwater.

[0042] Although the water holding frame 21 is on the roof, debris may be blown into the water holding frame 21 when it is windy. In order to prevent these debris from entering the water reservoir 22, the water holding frame 21 also includes a filter plate 3 with filter holes. The filter plate 3 is connected to the bottom plate 211. A filter cavity 215 is formed between the filter plate 3 and the bottom plate 211, and debris in the water is filtered through the filter plate 3.

[0043] The four corners of the filter plate 3 are provided with mounting pins 31, and the base plate 211 is provided with a retaining ring 216 for inserting the mounting pins 31. To install the filter plate 3, the filter plate 3 is placed from top to bottom into the water frame 21, so that the mounting pins 31 enter the retaining ring 216 from top to bottom. With the support of the retaining ring 216, the filter plate 3 is fixed to the base plate 211. In this embodiment, multiple filter plates 3 are provided, and the multiple filter plates 3 are laid out at intervals along the length of the base plate 211.

[0044] When rainwater falls into the water frame 21, it flows into the filter cavity 215 along the holes of the filter holes, and then flows into the water reservoir 22 from the water pipe, while debris is blocked by the filter plate 3, making it difficult for debris to enter the water reservoir 22 and the planting water tank 23.

[0045] See also Figure 5 Planting troughs 23 are located on the roof of building 1. Several planting troughs 23 are interconnected to maintain a consistent water level within the planting troughs 23. Furthermore, at least one planting trough 23 is connected to the water frame 21. During rain, some water within the water frame 21 flows into the reservoir 22, while the remaining water flows into the planting troughs 23. In this embodiment, eight planting troughs 23 are provided, four of which are connected end-to-end to form a "mouth" shape, while the remaining four are connected to different locations within the water frame 21, allowing water within the water frame 21 to flow into the planting troughs 23 more quickly and promptly.

[0046] A planting unit 4 is provided above the planting trough 23 to cover the notch 231 thereof. Plants are planted in the planting unit 4, and the notch 231 of the planting trough 23 is covered by the planting unit 4 to improve the viewing experience. Alternatively, a cover plate may be used to cover the notch 231 of the planting trough 23, and the user can choose according to actual circumstances.

[0047] See also Figure 6 and Figure 7Planting unit 4 includes a basin 41 and a water-absorbing sponge 42. Basin 41 contains soil and plants, and water-absorbing sponge 42 is located at the bottom of basin 41. A water exchange port 411 is defined at the bottom of basin 41, and water-absorbing sponge 42 covers this port. When a large amount of rainwater falls into basin 41, it can be drained through port 411. When basin 41 is short of water, water-absorbing sponge 42 absorbs water from the planting water tank 23 and transfers the water vapor into basin 41 through port 411, keeping the soil moist.

[0048] In order to stabilize the planting unit 4 in the planting water trough 23, the planting water trough 23 has a step 232, and the corresponding basin body 41 can be placed on the step 232; when the planting unit 4 is placed in the planting water trough 23, the basin body 41 is placed on the step 232. This not only stabilizes the planting unit 4 in the planting water trough 23, but also prevents the basin body 41 from squeezing the water-absorbing sponge 42, so that the water-absorbing sponge 42 always remains relaxed and able to absorb water.

[0049] See also Figure 7 and Figure 8 The planting unit 4 further includes a plurality of connecting rods 43, through which the water-absorbing sponge 42 is connected to the basin 41. The ends of the connecting rods 43 have external threads, and the connecting rods 43 penetrate into the water-absorbing sponge 42 from the bottom of the water-absorbing sponge 42, and the ends of the connecting rods 43 are screwed into the basin 41, so that the connecting rods 43 and the basin 41 are connected by threads.

[0050] In order to improve the stability of the water-absorbing sponge 42, the connecting rod 43 is fixedly connected to the limiting plate 44 by glue, and the limiting plate 44 is closer to the lower end of the connecting rod 43; when the connecting rod 43 penetrates the water-absorbing sponge 42 and is screwed into the basin body 41, the limiting plate 44 abuts against the water-absorbing sponge 42, and the water-absorbing sponge 42 is supported by the limiting plate 44, making the water-absorbing sponge 42 more stable and not easy to slip off the connecting rod 43.

[0051] In addition, the limiting plate 44 is spaced a distance from the lower end of the connecting rod 43; when the planting unit 4 is placed in the planting water trough 23, the lower end of the connecting rod 43 abuts against the bottom of the planting water trough 23, so that the water-absorbing sponge 42 always maintains a distance from the bottom of the planting water trough 23, thereby allowing the water in the planting water trough 23 to flow.

[0052] In order to prevent the water in the planting water tank 23 from overflowing, the planting water tank 23 is provided with an overflow port 24 connected to the water reservoir 22 . When the water level reaches a certain height, the water in the planting water tank 23 flows into the water reservoir 22 through the overflow port 24 .

[0053] The implementation principle of the energy-saving roof of a building in the embodiment of the present application is as follows: when it rains, the water frame 21 can hold and collect rainwater, and the rainwater in the water frame 21 flows into the water reservoir 22 through the water pipe. In addition, the rainwater in the water frame 21 will also flow into the planting water trough 23, and the water-absorbing sponge 42 will absorb the water in the planting water trough 23. When the soil in the pot body 41 is short of water, the moisture in the water-absorbing sponge 42 will penetrate into the pot body 41 through the exchange port 411, thereby providing water for the green plants in the pot body 41. When the plants in the planting unit 4 are short of water, the water in the water reservoir 22 can not only be poured into the planting unit 4, but also into the planting water trough 23. The planting water trough 23 serves as a backup water resource for the planting unit 4. The planting unit 4 only needs to be replenished with water after the water in the planting water trough 23 is used up. This expands the water storage capacity of the planting unit 4 and reduces the frequency of watering the green plants.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
