Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a green energy-saving roof cooling device. Background Technique

[0002] A building refers to a house that can provide space for our daily life, study, work, residence, production, and cultural activities. It usually includes a foundation, walls, a roof, doors, and windows, and can shelter from wind and rain, providing a space for people to live, work, study, entertain, store items, or carry out other activities.

[0003] However, the heat insulation and heat dissipation effects of the roofs of some existing buildings are poor. Especially in the hot summer, under the long-term sunlight irradiation, the temperature of the roof will rise rapidly, and the heat of the roof will be transferred to the interior of the building through the walls, resulting in an increase in the temperature inside the building and easily causing discomfort to users.

[0004] For this reason, roof cooling devices have emerged on the market. For example, the Chinese utility model patent with the publication number: CN215716631U discloses a roof cooling structure. This cooling structure can store rainwater, while insulating and cooling the roof and the interior, does not require the water pump to work continuously, and also makes up for the deficiency of the traditional pumping spray in reducing the roof temperature, reducing the consumption of water resources and electric energy, and can meet the user's usage requirements to a certain extent. However, when the water collection tank of this roof cooling structure is in use, due to the lack of a cover mechanism, the cooling water in the water collection tank is very easy to evaporate, which is likely to cause waste of the cooling water. At the same time, external dust is also easy to enter the water collection tank, thus affecting the overall use effect of the cooling device.

[0005] Therefore, there is an urgent need to redesign a new green energy-saving roof cooling device to solve the above problems. Content of the Utility Model

[0039] Please refer to Figures 1 to 8 , a green energy-saving roof cooling device of the present utility model includes a building 1, a cooling pipe 2 and a water collection tank mechanism 4.

[0040] Among them, the cooling pipe 2 is installed on the ridge of the building 1. The length of the cooling pipe 2 is slightly less than the length of the building 1. When the cooling water 402 is sprayed through the spray holes 201 on the cooling pipe 2, the uniformity of the roof cooling of the building 1 can be ensured.

[0041] In addition, a plurality of uniformly distributed spray holes 201 are provided on the cooling pipe 2, and the cooling water 402 in the cooling pipe 2 is sprayed out through the plurality of spray holes 201 for cooling the roof of the building 1.

[0042] Specifically, a connecting pipe 202 is connected to the cooling pipe 2. When the liquid extraction pump 403 operates, the liquid extraction pump 403 extracts the cooling water 402 and transports it into the cooling pipe 2 through the connecting pipe 202.

[0043] Please refer to Figures 1 to 8 , a pair of water collecting troughs 3 are installed on the building 1. The pair of water collecting troughs 3 are respectively installed at the lowest position of the roof of the building 1. The water collecting trough 3 is used to collect the liquid flowing on the roof of the building 1, including the returned cooling water 402 and rainwater.

[0044] Preferably, the length of the water collecting trough 3 is the same as that of the cooling pipe 2. The water collecting trough 3 is used to collect the cooling water 402 or rainwater flowing on the roof of the building 1, so that the cooling water 402 is not easily wasted, and at the same time, the reuse effect of subsequent rainwater can be improved.

[0045] Wherein, a water guiding platform is installed in the water collecting trough 3, and a return pipe 301 is connected to the water collecting trough 3. The return pipe 301 is arranged at the lowest position of the water guiding platform. The water guiding platform can quickly discharge the liquid collected in the water collecting trough 3, including the returned cooling water 402 and rainwater, so that the liquid in the water collecting trough 3 can enter the water collecting tank 401 through the return pipe 301.

[0046] Please refer to Figures 1 to 8 , the water collecting tank mechanism 4 is arranged on one side of the building 1. The water collecting tank mechanism 4 is used to temporarily store the cooling water 402 and can also collect rainwater.

[0047] Wherein, the water collecting tank mechanism 4 includes a water collecting tank 401. The cooling water 402 is arranged in the water collecting tank 401. A liquid extraction pump 403 is installed in the cooling water 402. The connecting pipe 202 is communicated with the output end of the liquid extraction pump 403. The liquid extraction pump 403 is installed in the storage cavity. The liquid extraction pump 403 is used to extract the cooling water 402 and transport the cooling water 402 to the cooling pipe 2.

[0048] When the liquid extraction pump 403 operates, the liquid extraction pump 403 extracts the cooling water 402 and transports the cooling water 402 to the cooling pipe 2 through the connecting pipe 202. The cooling water 402 in the cooling pipe 2 is evenly sprayed onto the roof through a plurality of spray holes 201, so as to ensure the uniformity of the roof cooling of the building 1.

[0049] Preferably, the cooling water 402 can be tap water or collected rainwater.

[0050] In addition, a partition plate 404 is arranged in the water collecting tank 401. A storage cavity and a filtering cavity are formed between the partition plate 404 and the inner wall of the water collecting tank 401. The storage cavity and the filtering cavity are communicated. The returned cooling water 402 or collected rainwater enters the storage cavity through the filtering cavity, so that the cooling water 402 or rainwater can be recycled.

[0051] Specifically, a filter screen 405 is inclinedly installed on the inner wall of the filtering chamber. The filter screen 405 is used to filter the liquid entering the filtering chamber, including the recycled cooling water 402 and the collected rainwater.

[0052] Optionally, the included angle between the filter screen 405 and the horizontal plane ranges from 15° to 20°, so that impurities are not easily blocked on the filter screen 405, ensuring the continuous filtering effect of the filter screen 405.

[0053] Preferably, the included angle between the filter screen 405 and the horizontal plane is 18°.

[0054] Please refer to Figures 1 to 8 , a return pipe 406 is installed on the water collection tank 401. One end of the return pipe 406 located in the filtering chamber is connected to a water distribution pipe 407. The water distribution pipe 407 is arranged above the filter screen 405, and a number of uniformly distributed through holes are provided on the water distribution pipe 407.

[0055] The liquid conveyed by the return pipe 406 can enter the water distribution pipe 407 and then be discharged through a number of through holes, so that the return liquid does not easily concentrate on passing through the filter screen 405, and thus the full utilization effect of the filter screen 405 can be ensured.

[0056] Among them, the other end of the return pipe 406 is connected to a three-way pipe, and the three-way pipe is respectively communicated with a pair of return pipes 301. The three-way pipe is used to connect the movable return pipe 301 and the return pipe 406.

[0057] Please refer to Figures 1 to 8 , a rainwater collection mechanism is installed on the water collection tank 401. The rainwater collection mechanism is used to collect rainwater so as to improve the green energy-saving effect of the roof cooling device.

[0058] Among them, the rainwater collection mechanism includes a rain collection cover 408. The rain collection cover 408 is communicated with the filtering chamber, and rainwater is collected through the rain collection cover 408, and the collected rainwater will enter the filtering chamber.

[0059] In addition, a cover 409 is provided on the rain collection cover 408. When the rain collection cover 408 does not collect rainwater, the cover 409 will cover the rain collection cover 408, thereby reducing the evaporation of the cooling water 402 in the water collection tank 401, improving the utilization rate of the cooling water 402, and at the same time preventing external dust from entering the cooling water 402 and ensuring the subsequent use effect of the cooling water 402.

[0060] Specifically, a first connecting member 410 is fixedly connected to the side wall of the rain collection cover 408, a second connecting member 411 is fixedly connected to the side wall of the cover 409, and the second connecting member 411 corresponds to the first connecting member 410. A control box 412 is installed above the water collection tank 401, and a motor 413 is installed in the control box 412. The output shaft of the motor 413 passes through the first connecting member 410 and is fixedly connected to the second connecting member 411.

[0061] When the motor 413 is running, the output shaft of the motor 413 can drive the cover 409 to rotate, thereby realizing the closing and opening of the rain collecting cover 408.

[0062] Please refer to Figures 1 to 8 , a limiting block 414 is connected to the inner wall of the first connecting member 410 where the output shaft of the motor 413 is located. The limiting block 414 is used to limit the cover 409, so that the cover 409 is not easily separated from the rain collecting cover 408.

[0063] Among them, a protective sleeve 415 is provided between the first connecting member 410 and the water collecting tank 401. The protective sleeve 415 is arranged outside the output shaft of the motor 413. The protective sleeve 415 is used to protect the output shaft of the motor 413, so that the motor 413 is not easily affected by rainwater.

[0064] In addition, a rain drop sensor 416 is installed on the top wall of the cover 409 for monitoring rainfall. That is, when the rain drop sensor 416 monitors rainfall in the outside world, the rain drop sensor 416 sends a monitoring signal to the control box 412, and the motor 413 will rotate, thereby driving the cover 409 to rotate, so that the rain collecting cover 408 can be opened to collect rainwater.

[0065] Preferably, the rain drop sensor 416 is a commercially available product and can be used directly.

[0066] During specific use, when it is necessary to cool the roof of the building 1, the liquid extraction pump 403 is operated. The liquid extraction pump 403 extracts the cooling water 402 and conveys the cooling water 402 to the cooling pipe 2 through the connecting pipe 202. The cooling water 402 in the cooling pipe 2 is evenly sprayed onto the roof through a plurality of spray holes 201, thereby playing a role in reducing the temperature of the roof of the building 1.

[0067] The cooling water 402 flowing on the roof of the building 1 will be collected by the water collecting tank 3. The cooling water 402 in the water collecting tank 3 enters the water distribution pipe 407 through the return pipe 301 and the return connection pipe 406, and then is discharged through a plurality of through holes and passes through the filter screen 405. The filter screen 405 can be used to remove impurities in the returned cooling water 402, so that the impurities do not easily affect the liquid extraction pump 403.

[0068] When the rain drop sensor 416 monitors rainfall in the outside world, the rain drop sensor 416 sends a monitoring signal to the control box 412. The control box 412 will control the motor 413 to run. The output shaft of the motor 413 can drive the cover 409 to rotate, so that the rain collecting cover 408 can be opened, that is Figure 1The state shown is such that rainwater can be collected by the rain collecting cover 408 at this time. In addition, the rainwater on the roof of the building 1 will also be collected by the rain collecting tank 3 and enter the water distribution pipe 407 through the return pipe 301 and the return connection pipe 406. The rainwater collected by the rain collecting tank 3 and the rain collecting cover 408 will all pass through the filter screen 405 for filtration and finally converge in the storage cavity for subsequent use.

[0069] When the rain drop sensor 416 does not detect rainfall in the outside world, the control box 412 will control the motor 413 to operate. The output shaft of the motor 413 can drive the cover 409 to rotate, enabling the cover 409 to cover the rain collecting cover 408, and thus the rain collecting cover 408 is in a closed state, that is Figure 4 the state shown. At this time, the evaporation of the cooling water 402 or rainwater in the water collecting tank 401 can be reduced to improve the utilization rate of the cooling water 402 or rainwater. At the same time, the entry of external dust into the cooling water 402 can also be reduced, facilitating the subsequent use of the cooling water 402.

[0070] The above description is only the implementation mode of the present utility model and does not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
