[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, the slider on the support disc rotates to the cam position, the bearing contacts the cam, and the bearing is pushed towards the center of the support disc. The gas spring is compressed, and the support frame moves towards the center of the support disc, driving the collection bottle to move towards the center of the support disc. The movement of the collection bottle causes the sealing cover on the collection bottle to leave the guide wheel on the lower side of the fixed ring. The upper side of the sealing cover loses the pressure of the guide wheel. Under the action of the torsion spring, the sealing cover automatically opens, and after opening, the end of the sealing cover away from the center of the support disc abuts against the fixed ring. At this time, the sealing cover is automatically opened into an obtuse angle state, which is beneficial for automatically opening the collection bottle for collection. The output end of the rotary workbench continues to rotate a certain angle, driving the support disc to rotate a certain angle. The bearing loses the oppression of the cam, the compressed gas spring resumes its original state, the support frame moves to the initial position, driving the collection bottle to move to the initial position, and the sealing cover moves to the guide wheel position. Under the action of the guide wheel, the sealing cover automatically closes, which is beneficial for automatically closing the collection bottle after collection; 2. The side plate of the filtering mechanism of the receiving device is used to block rainwater so that it will not flow out from the front and rear sides of the special-shaped rotating plate. The special-shaped rotating plate is used to collect rainwater. Under the restriction of the special-shaped rotating plate and the side plate, the rainwater enters the first opening in the middle side of the special-shaped rotating plate. The filter screen filters dust such as fallen leaves. When the impurities on one side of the filter screen accumulate too much and affect the passage of rainwater, the reduction motor can be started. The output end of the reduction motor rotates to drive the special-shaped rotating plate to rotate. The special-shaped rotating plate rotates to a preset position and stops. At this time, the filter screen on the other side is responsible for filtering rainwater. At the same time, too much rainwater flows over the upper side of the top plate or the upper side of the special-shaped rotating plate. When passing through the filter screen with more impurities, the filter screen is reversely flushed, so that the impurities on it can be automatically removed, which is beneficial for automatically removing the impurities on the filter screen and prolonging the continuous working time of the equipment; 3. Due to the first rotating bracket rotating in the left-right direction under the gravity of the second rotating bracket and the collection device on its upper side, and at the same time the second rotating bracket rotating in the front-rear direction on the first rotating bracket, when the barrel shakes under strong wind and rain weather, the lower side of the second rotating bracket is always in an approximately horizontal state, which is beneficial for keeping the inside of the equipment in a balanced state during rainwater collection, thereby improving the collection accuracy.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The "left", "right", "front", "rear", "upper" and "lower" mentioned in the following description are oriented in the perspective direction of the front view.

[0022] Embodiment 1: In some embodiments, please refer to Figures 1 - 7, an automatic collection device for atmospheric precipitation, including a frame 1 and a barrel body 2, and further including: a receiving device 3, a balancing device 4, a docking device 5, and a rotating sampling device 6. The barrel body 2 is fixedly installed on the upper side of the frame 1. The receiving device 3 is installed on the upper side of the barrel body 2. The balancing device 4 is installed inside the barrel body 2. The docking device 5 is installed on the balancing device 4. The rotating sampling device 6 is installed on the balancing device 4. The rotating sampling device 6 is located below the balancing device 4. The rotating sampling device 6 includes: a rotating workbench 61, a supporting disc 62, guide rails 63, sliders 64, gas springs 65, cams 66, a supporting frame 67, and bearings 68. The rotating workbench 61 is fixedly installed on the balancing device 4. The supporting disc 62 is fixedly installed at the output end of the rotating workbench 61. A plurality of the guide rails 63 are fixedly installed on the upper side of the supporting disc 62 in a circumferential array with the center of the supporting disc 62 as the center. The sliders 64 are slidably connected to the guide rails 63. One end of the gas spring 65 is fixedly installed on the slider 64, and the other end of the gas spring 65 is fixedly installed on the supporting disc 62. The cam 66 is fixedly installed on the left side of the balancing device 4. The supporting frame 67 is fixedly installed on the upper side of the slider 64. Protrusions are provided on the inner side wall of the supporting frame 67. A plurality of the bearings 68 are rotatably connected to one end of the slider 64 away from the center of the supporting disc 62. The rotating sampling device 6 further includes: a linkage cover-opening mechanism, which is installed in the middle side of the balancing device 4. A drain port 69 is provided on the side wall of the barrel body 2, and a maintenance door is provided on the barrel wall.

[0023] The receiving device 3 collects rainwater. The docking device 5 docks the rainwater collected by the receiving device 3 with the rotating sampling device 6, so that the rotating sampling device 6 samples and seals the rainwater. The balancing device 4 prevents the rotating sampling device 6 from being violently shaken when collecting rainwater in case of bad weather such as strong winds, resulting in an inconsistent rainwater collection volume, and more or less collection of some samples affects the later test results.

[0024] The output end of the rotating workbench 61 of the rotating sampling device 6 intermittently rotates by a certain angle. The rotation of the output end of the rotating workbench 61 drives the supporting disc 62 to rotate. The slider 64 on the supporting disc 62 rotates to the position of the cam 66, and the bearing 68 contacts the cam 66, pushing the bearing 68 towards the center direction of the supporting disc 62. The movement of the bearing 68 towards the center direction of the supporting disc 62 drives the slider 64 to move towards the center position of the supporting disc 62. The movement of the slider 64 towards the center position of the supporting disc 62 drives the supporting frame 67 to move towards the center position of the supporting disc 62, causing the gas spring 65 to be compressed.

[0025] The linkage opening mechanism includes: a collection bottle 610, a sealing cap 611, a fixing ring 612, and guide wheels 613. The collection bottle 610 is slidably connected to the protrusions on the inner sidewall of the support frame 67. The sealing cap 611 is rotatably connected to one end of the collection bottle 610 away from the center of the support disc 62 through a rotating shaft. The fixing ring 612 is fixedly installed on the balancing device 4. A plurality of the guide wheels 613 are rotatably connected to the lower side of the fixing ring 612 through rotating shafts. A torsion spring 615 is arranged on the rotating shaft of the sealing cap 611. One end of the torsion spring 615 is fixedly connected to the sealing cap 611, and the other end of the torsion spring 615 is fixedly connected to the collection bottle 610.

[0026] When the support frame 67 moves towards the center position of the support disc 62, it drives the collection bottle 610 to move towards the center position of the support disc 62. The movement of the collection bottle 610 causes the sealing cap 611 on the collection bottle 610 to leave the guide wheels 613 on the lower side of the fixing ring 612. The upper side of the sealing cap 611 loses the pressure of the guide wheels 613. Under the action of the torsion spring 615, the sealing cap 611 automatically opens, and after opening, the end of the sealing cap 611 away from the center of the support disc 62 abuts against the fixing ring 612. At this time, the sealing cap 611 is automatically opened into an obtuse angle state.

[0027] The output end of the rotary table 61 continues to rotate a certain angle, driving the support disc 62 to rotate a certain angle. The bearing 68 loses the oppression of the cam 66, and the compressed gas spring 65 restores. Due to the relatively slow rebound characteristic of the gas spring 65, when the gas spring 65 restores, it slowly pushes the slider 64 back to the initial position. The movement of the slider 64 to the initial position drives the support frame 67 to move to the initial position. The movement of the support frame 67 to the initial position drives the collection bottle 610 to move to the initial position. The sealing cap 611 moves to the position of the guide wheels 613, and under the action of the guide wheels 613, the sealing cap 611 automatically closes. When the collection bottle moves slowly, the liquid in the bottle will not shake excessively, which is beneficial to the stability during rainwater collection.

[0028] Embodiment 2: In some embodiments, as Figures 1 - 7 shown, as a preferred embodiment of the present invention, the balancing device 4 includes: a first rotating bracket 41 and a second rotating bracket 42. The first rotating bracket 41 is rotatably connected to the front and rear sides of the barrel body 2 through a rotating shaft. The second rotating bracket 42 is rotatably connected to the left and right sides of the first rotating bracket 41 through a rotating shaft.

[0029] When the barrel body 2 shakes under strong wind and rain weather, the first rotating bracket 41 rotates in the left and right directions under the gravity of the second rotating bracket 42 and the collection device on its upper side. At the same time, the second rotating bracket 42 rotates in the front and rear directions on the first rotating bracket 41, so that the lower side of the second rotating bracket 42 is always in an approximately horizontal state, which is beneficial to keeping the internal balance of the device during rainwater collection, thereby improving the collection accuracy.

[0030] The rotary table 61 is fixedly installed on the upper side of the second rotating bracket 42 of the balancing device 4, the cam 66 is fixedly installed on the left side of the second rotating bracket 42 of the balancing device 4, and the fixed ring 612 is fixedly installed in the middle of the second rotating bracket 42 of the balancing device 4.

[0031] The receiving device 3 includes: a top cover 31, a special-shaped rotating plate 32 and a reduction motor 33. The top cover 31 is fixedly installed on the upper side of the barrel body 2. The special-shaped rotating plate 32 is rotatably connected to the upper side of the top cover 31 through a rotating shaft. The reduction motor 33 is fixedly installed on the rear side of the top cover 31. The output end of the reduction motor 33 is fixedly connected to the rotating shaft of the special-shaped rotating plate 32. The reduction motor 33 has self-locking property. A first opening 34 is provided in the middle of the special-shaped rotating plate 32, and a second opening 35 is provided in the middle of the top cover 31. The top cover 31 is used to seal the upper side of the barrel body 2.

[0032] The receiving device 3 further includes: a filtering mechanism. The two filtering mechanisms are symmetrically installed on the special-shaped rotating plate 32 along the central axis of the special-shaped rotating plate 32. The filtering mechanism includes: side plates 36, a filter net 37 and a top plate 38. A plurality of the side plates 36 are fixedly installed on the upper side of the special-shaped rotating plate 32. The filter net 37 is fixedly installed at one end of the side plate 36 away from the central axis of the special-shaped rotating plate 32 through a bracket. The top plate 38 is fixedly installed on the upper side of the side plate 36 to seal the upper side of the position where the side plate 36 is close to the central axis of the special-shaped rotating plate 32, preventing impurities such as fallen leaves from entering the space formed by the side plate 36 and the special-shaped rotating plate 32.

[0033] The side plates 36 of the filtering mechanism of the receiving device 3 are used to block rainwater so that it will not flow out from the front and rear sides of the special-shaped rotating plate 32. The special-shaped rotating plate 32 is used to collect rainwater. Under the restriction of the special-shaped rotating plate 32 and the side plates 36, the rainwater enters the first opening 34 in the middle of the special-shaped rotating plate 32. The filter net 37 filters dust such as fallen leaves. When there is a large amount of impurities accumulated on one side of the filter net 37, affecting the passage of rainwater, the reduction motor 33 can be started. The output end of the reduction motor 33 rotates to drive the special-shaped rotating plate 32 to rotate. The special-shaped rotating plate 32 rotates to a preset position and stops. At this time, the filter net 37 on the other side is responsible for filtering rainwater. At the same time, when too much rainwater flows over the upper side of the top plate 38 or the upper side of the special-shaped rotating plate 32 and passes through the filter net 37 with more impurities, the filter net 37 is reversely flushed, so that the impurities on it can be automatically removed, which is beneficial to automatically removing the impurities on the filter net and prolonging the continuous working time of the equipment.

[0034] The docking device 5 includes: a first bellows 51, a tee 52, a first electric valve 53, a second bellows 54, a linear module 55, and a water outlet pipe 56. The upper side of the first bellows 51 is fixedly installed on the first opening 34 in the middle of the special-shaped rotating plate 32, and the lower side of the first bellows 51 is fixedly installed on the second opening 35 in the middle of the top cover 31. The upper side of the tee 52 is fixedly connected to the second opening 35 in the middle of the top cover 31. The first electric valve 53 is fixedly installed on the lower side of the tee 52.

The input end of the water outlet pipe 56 is fixedly connected to the end of the second bellows 54 away from the first electric valve 53.

[0035] Rainwater enters the second opening 35 in the middle of the top cover 31 through the first opening 34 in the middle of the special-shaped rotating plate 32 and the first bellows 51, and enters the tee 52 from the second opening 35. When rainwater collection is to be carried out, the first electric valve 53 is opened and the second electric valve 57 is closed. The output end of the linear module 55 moves downward to drive the water outlet pipe 56 to move downward. The water outlet pipe 56 enters the collection bottle 610 with the automatically opened sealing cover 611. The rainwater in the tee 52 enters the water outlet pipe 56 through the second bellows 54 of the docking device 5. The rainwater enters the collection bottle 610 through the water outlet pipe 56. The ultrasonic level sensor 614 detects the water level height in the collection bottle 610. When the water level reaches the preset value, the output end of the linear module 55 returns to its original position. At the same time, the first electric valve 53 is closed, and the output end of the rotary table 61 rotates to rotate the next collection bottle 610 to the position of the water outlet pipe 56 for the collection of the next rainwater sample.

[0036] The docking device 5 further includes: a second electric valve 57 and a third bellows 58. The second electric valve 57 is fixedly installed on the right side of the tee 52. One end of the third bellows 58 is fixedly connected to the end of the second electric valve 57 away from the tee 52. The other end of the third bellows 58 is fixedly connected to the drain opening 69 on the side wall of the barrel 2.

[0037] When the collection is completed and no further collection is required, the second electric valve 57 is opened and the first electric valve 53 is closed. The rainwater enters the second electric valve 57 through the tee 52 and then enters the third bellows 58, and is discharged out of the barrel 2 from the third bellows 58.
