Description

Technical Field

[0001] The invention relates to the technical field of precipitation collection, and in particular to an automatic precipitation collection device suitable for arid desert areas. Background Art

[0002] Precipitation refers to the condensation of water vapor obtained from the atmosphere on the ground. Rain, snow, dew, frost, sleet, hail and other phenomena in nature all belong to the category of precipitation. It is a product of the combined influence of factors such as geographical location, atmospheric circulation, and weather system conditions. It is the most basic link in the water cycle process and the basic parameter in the water balance equation. Precipitation is a general term for rain, snow, dew, frost, sleet, hail and other phenomena that occur in nature. There are three conditions for the formation of precipitation: ① There must be sufficient water vapor; ② The air mass must be lifted and cooled and condensed; ③ There must be more condensation nuclei. Precipitation is the origin of surface runoff and the main source of groundwater replenishment. In the arid desert areas of northwest my country, the climate is extremely dry, precipitation is scarce, evaporation is extremely large, wind and sand activities are frequent all year round, surface water is extremely scarce, sand and gravel are easily blown, and sandstorms often form. Therefore, the rational collection and utilization of precipitation in arid desert areas is an important way to solve the domestic water needs of residents in the area.

[0003] Due to the sparse vegetation and strong wind and sand in arid desert areas, a filter net is needed in the precipitation collection device to filter the precipitation to improve the cleanliness of water resources. However, after long-term use, the filter net is easily blocked by debris, which reduces the precipitation collection performance of the precipitation collection device. For example, the Chinese invention patent disclosed as CN109459279A discloses an automatic precipitation collection device for arid desert areas, including two water receiving funnels, a filter net, an insulation layer, a bracket, a water storage device, filter cotton, a precipitation collection bottle, a wire and a power supply system; wherein the two water receiving funnels are arranged up and down and fixed inside the insulation layer by a bracket, a water storage device is provided below the lower water receiving funnel, a filter cotton is provided below the water storage device, and the filter cotton is connected to the precipitation collection bottle below, and the power supply system transmits electricity through the wire and filters impurities through the filter net. There is a defect that the filter net is easily blocked by impurities after long-term use, which reduces the precipitation collection performance of the precipitation collection device.

[0023] like Figure 1 to Figure 6 As shown, an automatic precipitation collection device suitable for arid desert areas comprises a rainwater collection box 1, a coarse filter 4, a fine filter 6 and a drain pipe 20 with a water outlet valve arranged at the lower end of the side wall of the rainwater collection box 1, a rainwater purification box 2 connected thereto is arranged at the upper end of the rainwater collection box 1, a water receiving funnel 3 connected to the rainwater purification box 2 is liftably connected to the upper end of the rainwater purification box 2, the coarse filter 4 is arranged at the upper end of the water receiving funnel 3, four vertical rods 5 elastically connected to the rainwater purification box 2 are arranged on the coarse filter 4, and the fine filter 6 is arranged at the lower part of the interior of the rainwater purification box 2;

[0024] The upper part of the interior of the rainwater purification box 2 is rotatably connected with a rotating shaft 10, a tipping bucket 7 is arranged on the rotating shaft 10, a limit plate 9 is horizontally arranged directly below the tipping bucket 7, and two gears 11 are arranged on the rotating shaft 10. The two gears 11 are respectively located on the outside of the two opposite side walls of the rainwater purification box 2, and the outsides of the two opposite side walls of the rainwater purification box 2 are respectively connected with racks 12 for horizontal sliding. The two racks 12 are respectively meshed with the gears 11 on the same side, and a triangular top block 13 is respectively arranged at both ends of each rack 12. When in use, the rack 12 moves back and forth horizontally to drive the triangular top block 13 to intermittently squeeze the vertical rod 5 upward.

[0025] Working principle: when it rains, rainwater passes through the coarse filter 4 and falls on the tipping bucket 7 under the diversion effect of the water receiving funnel 3, driving the tipping bucket 7 to swing back and forth intermittently. The tipping bucket 7 drives the gear 11 to rotate back and forth intermittently through the rotating shaft 10. The gear 11 drives the triangular top block 13 to move back and forth intermittently through the rack 12, and intermittently squeezes the vertical rod 5 upward. In the time period when the vertical rod 5 is separated from the triangular top block 13, the vertical rod 5 drives the coarse filter 4 and the water receiving funnel 3 to vibrate up and down under the action of elastic force, and shakes off large particles of impurities such as dead branches and leaves on the coarse filter 4, so that the coarse filter 4 maintains good water permeability, improves the precipitation collection performance of the precipitation collection device, and the rainwater falling from the tipping bucket 7 finally falls into the rainwater collection box 1 for collection. When the collected rainwater needs to be used, the outlet valve is opened and the rainwater flows out from the drain pipe 20.

[0026] Preferably, a guide tube is provided in the middle of the upper end of the rainwater purification box 2, and the lower end of the water receiving funnel 3 is slidably connected to the guide tube. During the up and down vibration of the water receiving funnel 3, the lower end water outlet pipe of the water receiving funnel 3 is always slidably connected to the inside of the guide tube. The rainwater flowing out of the water receiving funnel 3 falls on the tipping bucket 7 under the diversion action of the guide tube, reducing the water flow difference and avoiding splashing of rainwater, so that all the rainwater falls on the tipping bucket 7, providing gravitational potential energy for the turning of the tipping bucket 7, thereby improving the cleaning effect of the coarse filter 4.

[0027] In order to improve the precipitation collection performance of the precipitation collection device, preferably, the entire tipping bucket 7 is a triangular structure, including two symmetrically arranged triangular water receiving grooves 8. When it rains, rainwater passes through the coarse filter 4 and falls into one of the triangular water receiving grooves 8 of the tipping bucket 7 under the diversion effect of the water receiving funnel 3. When the triangular water receiving groove 8 is full of rainwater, the triangular water receiving groove 8 will be driven to deflect to the side under the gravity of the rainwater, and stop under the limiting effect of the limiting plate 9, and the rainwater falls, and the rainwater falling from the water receiving funnel 3 will fall into the other triangular water receiving groove 8, so that The rainwater drives the tipping bucket 7 to deflect in the opposite direction and circulates back and forth, so that the tipping bucket 7 drives the gear 11 to make intermittent reciprocating rotation through the rotating shaft 10, and the gear 11 drives the triangular top block 13 to make intermittent left and right reciprocating movements through the rack 12, and intermittently squeezes the vertical rod 5 upward. In the time period when the vertical rod 5 is separated from the triangular top block 13, the vertical rod 5 drives the coarse filter screen 4 and the water receiving funnel 3 to vibrate up and down under the action of elastic force, and large particles of impurities such as dead branches and leaves on the coarse filter screen 4 are shaken off, so that the coarse filter screen 4 maintains good water permeability, and the precipitation collection performance of the precipitation collection device is improved.

[0028] In order to achieve the purpose of improving the precipitation collection performance of the precipitation collection device, preferably, the coarse filter screen 4 is an inverted "V" shaped structure. During the reciprocating up and down vibration process of the coarse filter screen 4, impurities fall along the "V" shaped slope of the coarse filter screen 4, and the cleaning effect is good.

[0029] In order to improve the precipitation collection performance of the precipitation collection device, preferably, the fine filter 6 is annular, and the edge of the fine filter 6 is provided with a conical cylinder 15 fixedly connected to the inner wall of the rainwater purification box 2.

[0030] A diversion funnel 14 is provided in the middle of the interior of the rainwater purification box 2, and a turntable 26 is rotatably connected below the diversion funnel 14. A plurality of drive plates 16 are provided in a circular array on the edge of the turntable 26. A driving bevel gear 17 is coaxially provided on the turntable 26. A driven bevel gear 18 meshing with the driving bevel gear 17 is rotatably connected inside the rainwater purification box 2, and a cleaning brush 19 is coaxially provided on the driven bevel gear 18. The bristles of the cleaning brush 19 are in contact with the upper surface of the fine filter 6.

[0031] During the rainwater collection process, rainwater falling from the tipping bucket 7 falls and impacts the driving plate 16 on the turntable 26 under the diversion effect of the diversion funnel 14. After receiving the impact of the rainwater, the driving plate 16 drives the turntable 26 to rotate. The rotating turntable 26 drives the driven bevel gear 18 to rotate synchronously through the active bevel gear 17. The driven bevel gear 18 drives the cleaning brush 19 to rotate synchronously to clean the fine filter 6, so as to prevent the mesh of the fine filter 6 from being blocked by small particles of impurities, thereby improving the precipitation collection performance of the precipitation collection device.

[0032] In order to achieve the purpose of improving the precipitation collection performance of the precipitation collection device, preferably, two guide cylinders 21 are respectively provided on the outside of the two opposite side walls of the rainwater purification box 2, the vertical rod 5 passes through the guide cylinder 21, and the vertical rod 5 is provided with a limiting ring 22 located inside the guide cylinder 21, and a spring 23 is provided between the limiting ring 22 and the inner top wall of the guide cylinder 21.

[0033] During the rainwater collection process, the gear 11 drives the triangular top block 13 to make intermittent left and right reciprocating movements through the rack 12, so that the triangular top block 13 intermittently squeezes the vertical rod 5 upward, and the spring 23 is compressed by the limit ring 22 during the squeezing process. When the triangular top block 13 is separated from the vertical rod 5, the spring 23 drives the coarse filter 4 to make up and down reciprocating vibration movements through the vertical rod 5, and shakes off large particles of impurities such as dead branches and leaves on the coarse filter 4, so that the coarse filter 4 maintains good water permeability, thereby improving the precipitation collection performance of the precipitation collection device.

[0034] In order to achieve the purpose of reducing friction and noise, preferably, the lower end of the vertical rod 5 is rotatably connected to a ball 24. Through the setting of the ball 24, the sliding friction between the lower end of the vertical rod 5 and the triangular top block 13 is converted into rolling friction between the ball 24 and the triangular top block 13, thereby changing the friction mode, reducing friction force, reducing noise, and helping to extend the service life of the device.

[0035] In order to achieve the purpose of improving the precipitation collection performance of the precipitation collection device, preferably, horizontal guide grooves 25 are respectively provided on the outside of the two opposite side walls of the rainwater purification box 2, and the two racks 12 are respectively slidably connected to the horizontal guide grooves 25 on the same side. In the process of the gear 11 driving the rack 12 to slide horizontally, the horizontal guide grooves 25 guide the horizontal sliding of the rack 12. The structure has strong stability, which is conducive to shaking off large particles of impurities such as dead branches and leaves on the coarse filter screen 4, so that the coarse filter screen 4 maintains good water permeability, and improves the precipitation collection performance of the precipitation collection device.

[0036] Preferably, an observation window is provided on the side wall of the rainwater collection box 1, and the setting of the observation window facilitates the real-time observation of the amount of rainwater collected in the rainwater collection box 1.

[0037] Compared with the prior art, the present invention is provided with a rainwater collection box 1, a coarse filter 4, a fine filter 6, a water outlet valve, a rainwater purification box 2, a drain pipe 20, a water receiving funnel 3, a vertical rod 5, a rotating shaft 10, a tipping bucket 7, a limit plate 9, a gear 11, a rack 12 and a triangular top block 13. When it rains, rainwater passes through the coarse filter 4 and falls on the tipping bucket 7 under the diversion effect of the water receiving funnel 3, driving the tipping bucket 7 to intermittently swing back and forth. The tipping bucket 7 drives the gear 11 through the rotating shaft 10. The wheel 11 rotates reciprocatingly intermittently, and the gear 11 drives the triangular top block 13 to move reciprocatingly left and right intermittently through the rack 12, and intermittently squeezes the vertical rod 5 upward. In the time period when the vertical rod 5 is separated from the triangular top block 13, the vertical rod 5 drives the coarse filter screen 4 and the water receiving funnel 3 to vibrate reciprocatingly up and down under the action of elastic force, so that large particles of impurities such as dead branches and leaves on the coarse filter screen 4 are shaken off, so that the coarse filter screen 4 maintains good water permeability, and the precipitation collection performance of the precipitation collection device is improved.
