Description

Technical Field

[0001] This invention relates to the field of water supply and drainage technology, and more specifically to a drainage collection device for building roofs. Background Technology

[0002] my country is a country with severe water shortages and uneven water resource distribution. To protect and utilize water resources, many buildings are equipped with rooftop rainwater harvesting systems to collect rainwater from the roofs. After treatment, the collected rainwater is used for irrigating plants, washing roads, and so on. However, current collection systems have the following problems: the rainwater at the beginning of each collection phase contains a lot of sand, gravel, mud, and other debris from the roof, which increases the operational burden on subsequent filtration and treatment processes. This results in problems such as easy clogging of the filtration devices, short service life, and high frequency of debris cleaning.

[0003] Therefore, how to solve the above-mentioned technical problems has become the challenge faced by this invention. Summary of the Invention

[0028] The mounting plate is provided with a mounting cover on its outer side, and the bottom of the mounting cover is provided with a water passage hole.

[0029] The rainwater pipe is located on the outer wall below the flip plate and has a switch door.

[0030] In actual use, the invention is as follows: In the initial state, the flip plate is in a horizontal position, and the second sliding block corresponds to the rainwater pipe. After rain, the rainwater first accumulates in the rainwater pipe above the flip plate. When the rainwater accumulates to a certain amount, it exerts a certain downward pressure on the flip plate. When the pressure sensor on one side receives the pressure signal and reaches the set value, the intelligent control terminal drives the motor to start and drive the flip plate to flip downward, fully open and fix its position. The water-soluble adhesive block on the bottom side of the flip plate absorbs water through the seepage holes, restores its stickiness, and sticks to the inner wall of the rainwater pipe, offsetting part of the pulling force of the first tension spring pulling the flip plate downward. The rainwater enters the water receiving tank through the first discharge pipe. When the rainwater in the water receiving tank reaches a certain amount, it overcomes the weight of the counterweight and flips downward, pouring the rainwater into the discharge box, and then discharging it through the second discharge pipe. The downward tilting process of the flipping plate drives the second rotating rod to rotate, which in turn drives the first helical gear to rotate. However, the first and second helical gears are in a one-way meshing state, so the first helical gear will not drive the first rope wheel to rotate and wind up the first pull rope. When the water tank tilts downward, it drives the rotating sleeve to rotate, which in turn drives the third helical gear to rotate. However, the third helical gear will not drive the fourth helical gear to rotate, thus not driving the second rope wheel to rotate and pull the second pull rope. After the water tank has tilted to collect all the rainwater, under the action of the counterweight, the water tank tilts back, returning to a horizontal state and the tilting angle changes from... With the limit rod in place, the third helical gear meshes with the fourth helical gear and rotates. After the second missing gear rotates, it meshes with the second gear, which in turn drives the second rope wheel to wind up the second pull rope. The second pull rope then pulls the second sliding block, aligning the first sliding block with the rainwater pipe. At this point, the missing tooth of the second missing gear re-aligns with the second gear. Driven by the second pull rope, the first rope wheel releases the first pull rope. Since the first gear and the missing tooth of the first missing gear are aligned at this time, it does not obstruct the rotation of the first rope wheel. The collecting mechanism begins to collect rainwater, at which point the rainwater contains relatively little debris. During periods of heavy rainfall, the rainwater pipe always aligns with the collection mechanism. During periods of longer intervals between rains, the roof accumulates a lot of sand and debris. As the water-soluble adhesive gradually loses moisture and its stickiness, the pressure sensor on the other side senses an increase in the force that causes the flip plate to flip upwards and reset. When the set value is reached, the drive motor starts, flipping the flip plate upwards to reset it to a horizontal position. The upward flipping process drives the first linkage mechanism. The first helical gear meshes with the second helical gear, causing the first missing gear to rotate. After the first missing gear rotates, it meshes with the first gear, thereby driving the first rope wheel to rotate and pull the first pull rope, which in turn pulls the first sliding block, aligning the second sliding block with the rainwater pipe. At this time, since the missing tooth of the second missing gear is opposite to the second gear, it will not obstruct the second rope wheel from releasing the second pull rope, thus preparing for the discharge and collection of rainwater when the next rain arrives.

[0031] In addition, the working process of the vibration mechanism is as follows: when the water receiving trough tilts a large amount of rainwater into the discharge box, it will impact the water receiving plate. The connecting plate will pull one side of the filter plate upward through the third pull rope. Thus, under the impact of rainwater and the combined action of the second, third and fourth tension springs, the filter plate vibrates, preventing debris from clogging the filter plate. At the same time, during the vibration process, debris will enter the discharge box along the inclined surface of the filter plate and be discharged uniformly, avoiding the problem of frequent manual cleaning of the filter components.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. This invention can discharge rainwater containing a lot of impurities such as sand and mud in the initial stage, and automatically switch to collection mode after discharge, thereby improving the cleanliness of the collected rainwater and reducing the burden of subsequent filtration and other further treatments.

[0034] 2. This invention can maintain rainwater collection during periods of frequent rainfall, and automatically switch to discharge mode after a period of no rain, ensuring that sand and soil accumulated on the roof over a long period of time are discharged first when the next rain washes it out.

[0035] 3. The vibration mechanism of the present invention uses the impact of rainwater discharge to vibrate the filter plate, and at the same time discharges the sand and gravel that are vibrated down, so as to avoid clogging of the filter plate. At the same time, the cleaning interval of the filtered material can be longer, which enhances the overall practicality of the device. Attached Figure Description

[0056] In actual use, the invention is as follows: In the initial state, the flip plate 3 is in a horizontal position, and the second sliding block 6 corresponds to the rainwater pipe 2. After rain, the rainwater first accumulates in the rainwater pipe 2 above the flip plate 3. When the rainwater accumulates to a certain amount, it exerts a certain downward pressure on the flip plate 2. When the pressure sensor 1015 on one side receives the pressure signal and the pressure reaches the set value, the drive motor 1014 starts and drives the flip plate 2 to flip downward, fully open and fix its position. The water-soluble adhesive block 304 on the bottom side of the flip plate 2 absorbs water through the seepage hole 303, restores its stickiness and sticks to the inner wall of the rainwater pipe 2, offsetting part of the pulling force of the first tension spring 302 pulling the flip plate 2 downward. The rainwater enters the water receiving tank 902 through the first discharge pipe 901. When the rainwater in the water receiving tank 902 reaches a certain amount, it overcomes the gravity of the counterweight block 905 and flips downward, pouring the rainwater into the discharge box 903 and then discharging it through the second discharge pipe 904. During the downward tilting process of the flip plate 2, the second rotating rod 301 rotates, which in turn drives the first helical gear 1001 to rotate. However, the first helical gear 1001 and the second helical gear 1002 are in a one-way meshing state. Therefore, at this time, the first helical gear 1001 will not drive the first rope wheel 1008 to rotate and wind up the first pull rope 1009. When the water receiving tank 902 tilts downward, it will drive the rotating sleeve 906 to rotate. The rotating sleeve 906 will drive the third helical gear 1101 to rotate, but the third helical gear 1101 will not drive the fourth helical gear 1102 to rotate, and thus will not drive the second rope wheel 1107 to rotate and pull the second pull rope 1108. After the water receiving tank 902 has tilted to collect the rainwater, under the action of the counterweight 905, the water receiving tank 902 tilts back, restoring the water receiving tank 902 to a horizontal state and tilting angle. The degree is limited by the limiting rod 908. At this time, the third helical gear 1101 meshes with the fourth helical gear 1102 and rotates. After the second missing gear 1104 rotates, it meshes with the second gear 1105, which in turn drives the second rope wheel 1107 to wind up the second pull rope 1108. The second pull rope 1108 then pulls the second sliding block 6, so that the first sliding block 5 corresponds with the rainwater pipe 2. At this time, the missing tooth part of the second missing gear 1104 corresponds to the second gear 1105 again. Driven by the second pull rope 1108, the first rope wheel 1008 releases the first pull rope 1009. Since the first gear 1006 corresponds to the missing tooth part of the first missing gear 1005 at this time, it will not hinder the rotation of the first rope wheel 1009. The collection mechanism 8 starts to collect rainwater. At this time, the rainwater has a low content of impurities.During periods of heavy rainfall, the rainwater pipe 2 always corresponds to the collection mechanism 8. During periods of longer intervals between rain showers, a significant amount of sand and debris accumulates on the roof. As the water-soluble adhesive gradually loses moisture, its adhesive properties also diminish. Under the pull of the first tension spring 302, the pressure sensor 1015 on the other side senses an increase in the force causing the flip plate 3 to flip upwards and reset. When the set value is reached, the drive motor 1014 starts, flipping the flip plate 3 upwards to reset it to a horizontal position. This upward flipping process drives the first linkage mechanism 10, and the first inclined... Gear 1001 meshes with the second helical gear 1002, causing the first missing gear 1005 to rotate. After the first missing gear 1005 rotates, it meshes with the first gear 1006, which in turn drives the first rope wheel 1008 to rotate and pull the first pull rope 1009, thereby pulling the first sliding block 5, so that the second sliding block 6 corresponds with the rainwater pipe 2. At this time, since the missing tooth part of the second missing gear 1104 is opposite to the second gear 1105, it will not hinder the second rope wheel from releasing the second pull rope, thus preparing for the rainwater discharge and collection when the next rain arrives.

[0057] In addition, the working process of the vibration mechanism 12 is as follows: when the water receiving trough 902 tilts a large amount of rainwater into the discharge box 903, it will impact the water receiving plate 1204. The connecting plate 1203 will pull one side of the filter plate 803 upward through the third pull rope 1209. Thus, under the impact of rainwater and the combined action of the second tension spring 1201, the third tension spring 1202, and the fourth tension spring 1205, the filter plate 803 will vibrate, preventing debris from clogging the filter plate. At the same time, during the vibration process, debris will enter the discharge box 903 along the inclined surface of the filter plate 803 and be discharged uniformly, avoiding the problem of frequent manual cleaning of the filter components.

[0058] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
