Description

Technical Field

[0003] In the prior art, a Chinese patent with authorization announcement number CN215932177U discloses a rainwater collection device for meteorological research. Through the use of a control mechanism, it is easy to control the on and off of the warning light, so as to remind researchers that rainwater is well collected, so that researchers can deal with rainwater in time and improve the accuracy of experimental data; through the use of adjustment components, researchers can adjust the position of the contact according to the amount of rainfall required for the experiment, thereby avoiding excessive collection of rainwater and improving the efficiency of rainwater collection.

[0004] The above-mentioned existing technical solutions have the following defects: the connection between the rain storage box and the rain collecting hopper lacks a flexible closing structure.

In addition, in some research scenarios, it is necessary to collect rainwater in a fixed period of time. If the rain storage box cannot be closed in time, it will affect the accuracy of the research results.

[0025] like Figures 1 to 3 As shown, a rainwater collection device comprises a collection box 1, a water inlet bucket 2 is fixedly installed on the top surface of the collection box 1, a waterproof cavity 4 is opened inside the top wall of the collection box 1, a capacity adjustment mechanism 5 is provided on the inner wall surface of the collection box 1, a rotating switching component 6 is provided on the top surface of the inner wall of the collection box 1, a half filter plate 7 is fixedly installed on the surface of the rotating switching component 6, a water baffle 15 is radially fixedly installed on the middle part of the surface of the half filter plate 7, and a filter hole 8 is opened on the surface located on the left side of the water baffle 15, a waterproof baffle 9 is fixedly installed on the side of the half filter plate 7, the waterproof baffle 9 is rotatably installed on the top surface of the inner wall of the collection box 1 and partially fits the side surface of the inner wall of the collection box 1, an overflow port 10 is opened on the position where the surface of the waterproof baffle 9 fits on the side of the collection box 1 and on the surface of the waterproof baffle 9, a control component 11 is provided in the waterproof cavity 4, a warning light 12 is fixedly installed on the top surface of the collection box 1, the control component 11 and the capacity adjustment mechanism 5, the rotating switching component 6 and the warning light 12 are all electrically connected, and a water outlet pipe 13 is fixedly installed on the side wall surface of the collection box 1.

[0026] More specifically, the collection period is set by the control component 11 or the sensing water level is adjusted by the capacity adjustment mechanism 5. When the collection period ends or the water level reaches the sensing position of the capacity adjustment mechanism 5, the control component 11 drives the rotating switching component 6 to operate, and the rotating switching component 6 drives the half filter plate 7 to rotate, so that the half surface of the half filter plate 7 without the filter hole 8 rotates to the bottom of the water inlet bucket 2. At this time, the waterproof baffle 9 and the overflow port 10 opened on the surface of the collection box 1 are aligned, and the water falls on the half surface of the half filter plate 7 without the filter hole 8 and is isolated by the waterproof baffle 15 and the waterproof baffle 9. After the water gathers to a certain height, it flows out through the overflow port 10 on the surface of the waterproof baffle 9 and the overflow port 10 on the surface of the collection box 1. It can be used to avoid collection period errors and to prevent excessive rainwater from continuing to enter the collection box 1. Even if the researchers fail to take it in time, it will not affect the accurate collection of rainwater, effectively ensuring the accuracy of rainwater research data.

[0027] An observation window 3 is fixedly installed on the front of the collection box 1. The observation window 3 is made of tempered glass. The observation window 3 is arranged right in front of the capacity adjustment mechanism 5. A valve 14 is arranged on the surface of the water outlet pipe 13.

[0028] Specifically, by turning the valve 14 to open the outlet pipe 13, the rainwater collected in the collection box 1 can be poured out, and the sensing water level of the capacity adjustment mechanism 5 can be observed and set through the observation window 3, and the actual water level can be observed at the same time.

[0029] The capacity adjustment mechanism 5 includes a first motor 501 and a sliding column 503. The first motor 501 is fixedly installed on the bottom surface of the inner wall of the waterproof cavity 4. The output end of the first motor 501 is fixedly connected to a threaded rod 502. The sliding column 503 is fixedly installed between the upper and lower side walls of the collecting box 1. A scale line 504 is engraved on the front of the sliding column 503. A lifting block 505 is threadedly installed on the surface of the threaded rod 502. The lifting block 505 is slidably installed on the surface of the sliding column 503. A pressure sensor 506 for sensing the water body is fixedly installed on the bottom surface of the lifting block 505.

[0030] Specifically, the output end of the first motor 501 drives the threaded rod 502 to rotate. Since the lifting block 505 is slidably installed on the surface of the sliding column 503 and is threadedly connected to the surface of the threaded rod 502, the rotation of the threaded rod 502 will drive the lifting block 505 to rise and fall. The height of the pressure sensor 506 fixedly installed on its bottom surface is adjusted by lifting and lowering the lifting block 505, so that the pressure sensor 506 is flush with the height of the scale value that needs to be set. When the water body gathers to the set height, it contacts the surface of the pressure sensor 506, generates pressure on the pressure sensor 506, and then causes the pressure sensor 506 to generate a corresponding signal, which is transmitted to the control component 11, so that the control component 11 performs corresponding processing and action.

[0031] The rotating switching component 6 includes a second motor 601, which is fixedly installed on the bottom surface of the inner wall of the valve 14. The output end of the second motor 601 is fixedly connected to a rotating shaft 602. The rotating shaft 602 passes through the top surface of the inner wall of the collection box 1 and is rotatably arranged. A mounting seat 603 is fixedly installed on the bottom surface of the rotating shaft 602, and the half filter plate 7 is fixedly installed on the surface of the mounting seat 603.

[0032] Specifically, the output end of the second motor 601 drives the rotating shaft 602 and the mounting seat 603 to rotate synchronously, and the rotation of the mounting seat 603 drives the half filter plate 7, the waterproof baffle 9 and the water-blocking plate 15 to rotate synchronously, thereby switching the position of the filter hole 8 on the surface of the half filter plate 7. When the filter hole 8 is located directly below the water inlet hopper 2, rainwater can smoothly enter the collection box 1. When the filter hole 8 leaves the bottom of the water inlet hopper 2, the rainwater is isolated by the half filter plate 7 and cannot enter the collection box 1.

[0033] The warning light 12 includes a support rod 121 and a light body 122 . The support rod 121 is fixedly mounted on the top surface of the collection box 1 , and the light body 122 is fixedly mounted on the support rod 121 .

[0034] Specifically, the support rod 121 may be a hollow rod, the interior of which is used to pass electrical wires. When water collection is completed, the control component 11 controls the lamp body 122 to flash, which serves as a prompt.

[0035] The control component 11 includes a control circuit board 111, a battery 112, a control panel 113 and a rain cover 114. The control circuit board 111 and the battery 112 are fixedly installed on the inner wall surface of the waterproof cavity 4, the control panel 113 is fixedly installed on the top surface of the collection box 1, and the rain cover 114 is fixedly installed on the surface of the control panel 113. The control circuit board 111 is electrically connected to the battery 112, the control panel 113, the first motor 501, the pressure sensor 506, the second motor 601, and the lamp body 122.

[0036] Specifically, the battery 112 is used to power the control circuit board 111, which supplies power to each power-consuming structure. The collection period, collection amount and other information are input into the control circuit board 111 through the control panel 113. The start and stop of the first motor 501 and the second motor 601 are controlled by the control circuit board 111. The pressure sensor 506 senses the electrical signal generated by the water body and transmits it to the control circuit board 111. The control circuit board 111 processes the signal and outputs a control signal to the second motor 601. After the rainwater collection is completed, the control circuit board 111 sends a signal to the lamp body 122 to make the lamp body 122 flash. The rain cover 114 is used to provide waterproof protection for the control panel 113.

[0037] In summary: the control component 11 drives the rotating switching component 6 to operate, and the rotating switching component 6 drives the half surface of the half filter plate 7 without the filter hole 8 to rotate to the bottom of the water inlet bucket 2. The water body is isolated by the half filter plate 7, the water baffle 15 and the waterproof baffle 9 and flows out through the overflow port 10. It can be used to avoid errors in the collection period, and can also be used to prevent excessive rainwater from continuing to enter the collection box 1. Even if the researchers fail to take it in time, it will not affect the accurate collection of rainwater, and effectively ensure the accuracy of rainwater research data.
