The inner wall of the guide cylinder 4 is provided with silica gel, so that the buffering effect is enhanced.
The lower surface of the interior of the ice-collecting barrel 5 is in an inclined state that the area close to the discharge valve 10 is low and the area far away from the discharge valve 10 is high, so that hail is discharged conveniently.
The ice-collecting barrel is characterized by further comprising a guide disc 101, wherein the guide disc 101 is fixedly connected to the upper side of the interior of the ice-collecting barrel 5, and the guide disc 101 is used for distributing the downflow rainwater, so that the downflow impulse leaves are prevented from flowing downwards due to the concentration of the rainwater.
The upper side of the middle part of the deflector disc 101 is conical, so that rainwater is prevented from remaining on the upper side of the middle part of the deflector disc 101 when flowing down.
The specific working steps are as follows:
before working, the external water delivery equipment is connected with the water inlet pipe 102 and the water delivery pipe 111 respectively; when rainwater needs to be collected, the electric rotating roller 2 drives the baffle plate 3 to rotate upwards to be opened, so that the baffle plate 3 does not block the guide cylinder 4 any more, and then the rainwater falls into the guide cylinder 4, and the rainwater falling into the guide cylinder 4 flows downwards along the inner wall of the guide cylinder 4 and falls into the water collection cylinder 6;
when hail is contained in rain, the hail is blocked by the filter screen 8, the hail is prevented from falling into the water collecting barrel 6, and as the filter screen 8 is conical, the hail rolls along the inclined plane of the filter screen 8 when falling into the filter screen 8, so as to move to the outer side of the filter screen 8, further the hail falls into a space between the ice collecting barrel 5 and the water collecting barrel 6, separation of the hail and rainwater is realized, the guide barrel 4 is in an inverted cone shape and the outlet is positioned in the middle, so that most of the hail can directly fall on the inner wall of the guide barrel 4 for blocking, and the impact force of the hail can be effectively slowed down; the hail falling to the middle part of the guide cylinder 4 is blocked by the connecting rod of the guide disk 101, so that the phenomenon that the filter screen 8 is damaged due to overlarge impact force of the hail directly impacting the filter screen 8 is avoided;
because the lower surface of the interior of the ice-collecting barrel 5 is inclined, when the hail falls into the ice-collecting barrel 5, the hail moves towards the direction of the discharge valve 10 and is accumulated around the discharge valve 10, when the hail is required to be taken out and the content of the hail is calculated in raining, a charging barrel is placed below the discharge valve 10, then the discharge valve 10 is opened, the hail falls into the charging barrel, then the collected hail is calculated, the effect of keeping the function of intercepting leaves is realized, meanwhile, the hail and rainwater can be separately collected, so that the content of the hail in the rainwater can be more accurately detected, and in this way, the hail content can be compared with data simulated by a computer, so that the calibration of the computer is realized, and the simulation accuracy of the computer is further improved;
and when hail is down, also there is the leaf attached to filter screen 8, and rivers can concentrate at this moment and flow down in guide cylinder 4 inside region, and because the water that flows down is more, filter screen 8 can't directly make under water fall, this moment part water will flow towards filter screen 8 outside, at this moment the water that flows will promote the leaf to remove towards filter screen 8 outside, and then lead to also having the leaf in the hail, and then lead to the hail to take out the back and need pick out the leaf, cause the waste of time, so water conservancy diversion dish 101 can shunt the rainwater that flows down, avoid the rainwater to concentrate the flow of downflow impulse leaf.

The water outlet hole 4b is inclined downwards, so that the sprayed water can directly wash the inner wall of the guide cylinder 4.
The specific working steps are as follows:
when the hail falls on the filter screen 8, the water spraying frame 104 plays a supporting role, the hail is prevented from smashing the filter screen 8 due to overlarge impact force of the hail, then the falling hail rolls towards the outer side of the filter screen 8, the filter screen 8 is scratched by the hail when the hail falls, and the crushed hail falls into the water collecting barrel 6, so when the hail is contained in rainwater, the DD motor 103 drives the water spraying frame 104 to rotate anticlockwise at an angle from top to bottom, when the water spraying frame 104 contacts with the stop 116, and then stops rotating, when the water spraying frame 104 rotates away from the automatic collecting barrel 113, the water spraying frame 104 pulls the water blocking cloth 114 to be unfolded and attached to the lower surface of the filter screen 8, then contacts with the stop 116, the lower part of the water spraying frame 104 is covered by the water blocking cloth 114, at the moment, the hail which is supported and falls into the water collecting barrel 6 is prevented from being scratched by the filter screen 8, even if the crushed hail is scratched, the hail flows downwards along the unfolded cloth 114 and does not enter into the water collecting barrel 6, and then the rainwater is separated into the water collecting barrel 112a along the water collecting barrel 6, and then the rainwater is separated;
after the rainwater is taken out, the external water delivery device delivers pure water to the water inlet pipe 102, so that the water sequentially enters the water delivery hole 104a from the annular water channel and the flow channel 101a, and then is sprayed out from the water spraying port 104b, the pure water sprayed out from the water spraying port 104b can impact leaves attached to the filter screen 8, and then the leaves are flushed into a space between the ice-collecting barrel 5 and the water-collecting barrel 6, so that the leaves are prevented from being attached to the filter screen 8 for a long time to rot, the contact of the rainwater with the rotten leaves is avoided, the change of the components in the rainwater is caused, the problem of detection results is caused, and when the pure water is sprayed out, the DD motor 103 drives the water spraying frame 104 to rotate anticlockwise at an angle from top to bottom, and further, the situation that a region cannot be sprayed is avoided, because the water spraying frame 104 is contacted with the stop 116 at the moment and the annular plate 112 can stably rotate on the water collecting barrel 6, and the annular plate 112 can be pushed to rotate together at the moment; since the rainwater can flow down along the inner wall of the guide cylinder 4, part of the leaves are attached to the inner wall of the guide cylinder 4, when the filter screen 8 is cleaned, the external water equipment can convey purified water to the water conveying pipe 111, so that the purified water flows down along the inner wall of the guide cylinder 4, and the attached leaves are washed away;
at this time, since the water retaining cloth 114 is in the unfolded state, the sprayed water falls on the unfolded water retaining cloth 114, so that the sprayed water flows downwards on the water retaining cloth 114, and when the water on the water retaining cloth 114 is in the flowing state, leaves on the filter screen 8 are driven to flow, at this time, the high pressure of the water sprayed from the water spraying port 104b is avoided, and only the leaves clamped in the filter screen 8 are sprayed and taken away by the flowing water, so that the consumption of the water is reduced; because the purified water is blocked by the water retaining cloth 114 and flows along the water retaining cloth 114, the filter screen 8 is in a state of being soaked by the purified water at the moment, and compared with pure water spraying, the washing effect of the filter screen 8 is stronger and the water consumption is less;
it should be noted that, the first connection block 115 is used for fixing the automatic winding drum 113, so as to avoid bending at the connection position between the automatic winding drum 113 and the annular plate 112 due to centrifugal force when the automatic winding drum 113 rotates.
Example 3
On the basis of the embodiment 2, as shown in fig. 4-5, a water baffle 117 is further included; three water baffles 117 are fixedly connected to the side part of the water spraying frame 104 at equal intervals; the gap between the water spraying frame 104 and the automatic winding drum 113 is blocked by the water baffle 117, so that crushed ice is prevented from falling into the water collecting drum 6 through the gap.
The specific working steps are as follows:
in the initial state, as shown in fig. 4, the water retaining cloth 114 is in a winding state, each water spraying frame 104 corresponds to the automatic winding drum 113 one by one, because the water spraying frames 104 and the automatic winding drum 113 have a height difference in assembly height, when the water spraying frames 104 rotate to be in contact with the other stop block 116 and the water retaining cloth 114 is unfolded, the water spraying frames 104 are still above the automatic winding drum 113, a gap exists between the lower surface of the water spraying frames 104 and the other automatic winding drum 113, and in the state shown in fig. 5, the water spraying frames 104 and the automatic winding drum 113 cannot be bonded all the time, so that purified water, crushed ice and the like can be prevented from directly entering the water collecting drum 6 from the gap, and therefore, the water retaining plate 117 is arranged to block the gap between the water spraying frames 104 and the automatic winding drum 113, and crushed ice can be prevented from falling into the water collecting drum 6 through the gap.
The foregoing has outlined rather broadly the more detailed description of the present application, wherein specific examples have been provided to illustrate the principles and embodiments of the present application, the description of the examples being provided solely to assist in the understanding of the method of the present application and the core concepts thereof; meanwhile, as those skilled in the art will have modifications in the specific embodiments and application scope in accordance with the ideas of the present application, the present description should not be construed as limiting the present application in view of the above.
