DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
As shown in fig. 1-3, in one embodiment, the present invention provides a precipitation monitoring device 100 comprising a piezoelectric power generation unit 10 and a monitoring unit 20, wherein:
the piezoelectric power generation unit 10, the piezoelectric power generation unit 10 includes at least two elastic cantilevers 11, each elastic cantilever 11 is triggered when receiving a characteristic fluid dropped, and the piezoelectric power generation unit 10 is configured to convert kinetic energy generated when each elastic cantilever 11 is triggered into electric energy.
Specifically, since the characteristic fluid will impact and vibrate the piezoelectric structure of the piezoelectric power generation unit 10 when falling on the piezoelectric structure, the piezoelectric power generation unit 10 can convert the kinetic energy generated when the characteristic fluid falls into electric energy by using the piezoelectric effect caused by the vibration of the piezoelectric structure, so as to provide energy for the monitoring unit 20. Each elastic cantilever 11 is used for receiving characteristic fluid which drops, the elastic cantilever 11 promotes itself to generate elastic vibration under the impact of the characteristic fluid which drops, the impact process is actually a process of energy conversion, specifically, when the characteristic fluid which drops is received, the elastic cantilever 11 converts kinetic energy and potential energy of the characteristic fluid which drops into kinetic energy so as to promote itself to generate elastic vibration, the elastic cantilever 11 which generates elastic vibration is regarded as being in a triggered state, and when the elastic cantilever 11 is triggered, the piezoelectric power generation unit 10 generates piezoelectric effect under the elastic vibration of the elastic cantilever 11 so as to convert the kinetic energy of the elastic vibration of the elastic cantilever 11 into electric energy, thereby realizing the function of autonomous power generation through the piezoelectric effect.
It should be noted that, the type of the characteristic fluid may be set according to the actual use scenario, for example, in this embodiment, the precipitation monitoring device 100 is used for monitoring the precipitation, whereas in nature, precipitation is a common natural phenomenon, the precipitation process contains a lot of energy, which is represented by kinetic energy and potential energy of the falling rainwater, and the falling characteristic fluid is the falling rainwater.
While the structural form of the elastic cantilever 11 is not limited, for example, in some embodiments, the elastic cantilever 11 is a piezoelectric sheet, and at this time, the piezoelectric sheet directly serves as a piezoelectric structure of the piezoelectric power generating unit 10, which can induce a piezoelectric effect in the case of vibration. Of course, in other embodiments, the elastic cantilever 11 may be connected to the piezoelectric structure of the piezoelectric power generating unit 10, and in this case, the piezoelectric structure of the piezoelectric power generating unit 10 may be triggered to generate a piezoelectric effect by using kinetic energy generated when the elastic cantilever 11 is triggered.
In addition, the number of the elastic cantilevers 11 is not limited, and for example, in some embodiments, the elastic cantilevers 11 include four and are disposed at intervals from each other.
And the monitoring unit 20 is connected with the piezoelectric power generation unit 10 and is used for generating precipitation grade information according to the number of the triggered elastic cantilevers 11 under the driving of electric energy. The precipitation level information is set in association with the number of triggered elastic cantilevers 11, and before the precipitation monitoring device 100 monitors, a plurality of precipitation level information needs to be preset, and different level information corresponds to the number of triggered elastic cantilevers 11. For example, in some embodiments, when four elastic cantilevers 11 are provided, then four precipitation level information is preset to be associated with the case when the number of triggered elastic cantilevers 11 is one, two, three, and four, respectively.
In the precipitation monitoring device 100, the elastic cantilevers 11 of the piezoelectric power generation unit 10 receive the characteristic fluid which drops, and the elastic cantilevers 11 convert kinetic energy and potential energy of the characteristic fluid during dropping into kinetic energy of elastic vibration of the elastic cantilevers, so that the piezoelectric power generation unit 10 is caused to generate piezoelectric effect to acquire electric energy, the monitoring unit 20 can utilize the electric energy of the part to detect precipitation detection work, and the precipitation monitoring device 100 can provide electric energy for the self without additional external power supply because the electric energy is generated independently by the piezoelectric power generation unit 10, so that the precipitation monitoring device 100 can be guaranteed to normally perform precipitation monitoring work, and meanwhile, the monitoring unit 20 can also directly generate precipitation grade information according to the number of the triggered elastic cantilevers 11, thereby completing precipitation monitoring work in real time and rapidly and improving precipitation monitoring efficiency.
In some embodiments, precipitation monitoring device 100 further includes a water collection unit 30 having a receiving cavity 310. Wherein:
the accommodating cavity 310 is used for accommodating the characteristic fluid, the water collecting unit 30 is provided with at least two through holes 301 penetrating through the water collecting unit, the through holes 301 are respectively arranged opposite to the elastic cantilevers 11 one by one at intervals, and each through hole 301 is used for guiding the characteristic fluid in the accommodating cavity 310 to drop to the corresponding elastic cantilever 11.
In some embodiments, the water collection unit 30 includes a water collection housing 31 and a water blocking baffle portion 32. Wherein:
the water blocking plate portion 32 is fixed inside the water collecting case 31 and forms a housing chamber 310 together with the water collecting case 31, and each through hole 301 is provided to penetrate the water blocking plate portion 32.
Specifically, the water collecting shell 31 is provided with a first opening 311 and a second opening 312 which are arranged at opposite intervals, the first opening 311 is positioned at one side far away from the piezoelectric power generation unit 10, and the first opening 311 can be used for allowing characteristic fluid to flow into the accommodating cavity 310 to collect the characteristic fluid; the second opening 312 is located at a side close to the piezoelectric power generating unit 10 and is disposed toward the piezoelectric power generating unit 10, and the second opening 312 allows the characteristic fluid flowing out of the through hole 301 to drip toward the elastic cantilever 11.
The water blocking plate portion 32 includes at least two step plates 321 arranged at intervals in the first direction (i.e., the X-axis direction, which is the direction from the second opening 312 toward the first opening 311), and side walls 322 connecting the adjacent two step plates 321, respectively, each step plate 321 being provided with a through hole 301 penetrating therethrough; it should be noted that, the plurality of step plates 321 and the side walls 322 together divide the accommodating cavity 310 into a plurality of sub accommodating cavities, and each sub accommodating cavity correspondingly accommodates a characteristic fluid with different volumes.
It should be noted that, the distribution manner of the plurality of step plates 321 may be adjusted according to the actual design requirement, and considering that the plurality of through holes 301 are too densely arranged, the arrangement of the elastic cantilevers 11 is too concentrated, which is easy to cause the phenomenon that part of the elastic cantilevers 11 is triggered by mistake due to interference when the two adjacent elastic cantilevers 11 vibrate, so in some embodiments, the plurality of step plates 321 are uniformly distributed around the central axis of the water collecting shell 31, the plurality of through holes can be uniformly distributed around the central axis of the water collecting shell 31, correspondingly, the plurality of elastic cantilevers 11 are also uniformly distributed around the central axis of the water collecting shell 31, so that the distribution of the plurality of elastic cantilevers 11 is reasonable, a reasonable distance interval can be provided between the two adjacent elastic cantilevers 11, which is favorable for improving the accuracy of monitoring and ensuring the reliability of monitoring.
For example, in some embodiments, the stepped plate 321 includes a first plate 3211, a second plate 3212, a third plate 3213, and a fourth plate 3214 sequentially disposed at intervals along a first direction, a sub-receiving cavity formed between the first plate 3211 and the second plate 3212 is a first cavity 3101, a sub-receiving cavity formed between the second plate 3212 and the third plate 3213 is a second cavity 3102, a sub-receiving cavity formed between the third plate 3213 and the fourth plate 3214 is a third cavity 3103, and a sub-receiving cavity formed between the fourth plate 3214 and the first opening 311 is a fourth cavity 3104, where the first cavity 3101, the second cavity 3102, the third cavity 3103, and the fourth cavity 3104 collectively form the receiving cavity 310. It should be noted that, the first cavity 3101, the second cavity 3102, the third cavity 3103 and the fourth cavity 3104 respectively receive characteristic fluids with different volumes, and the receiving volumes of the characteristic fluids corresponding to the sub-receiving cavities may be specifically set according to the actual use requirement, for example, in some embodiments, the volume of the first cavity 3101 is 20ml, the volume of the second cavity 3102 is 40ml, the volume of the third cavity 3103 is 60ml, and the volume of the fourth cavity 3104 is greater than 80ml, which further includes:
when the volume of the characteristic fluid in the accommodating cavity is 0-20ml, the characteristic fluid can drop downwards from the through hole of the first plate 3211, so that one elastic cantilever 11 is triggered;
when the volume of the characteristic fluid in the accommodating cavity is 20-60ml (60 ml is the common volume of the first cavity 3101 and the second cavity 3102), the characteristic fluid can drop downwards from the through holes of the first plate 3211 and the second plate 3212 at the same time, so as to trigger the two elastic cantilevers 11;
when the volume of the characteristic fluid in the holding cavity is 60-120ml (120 ml is the volume of the first cavity 3101, the second cavity 3102 and the third cavity 3103 together), the characteristic fluid can drop downwards from the through holes of the first plate 3211, the second plate 3212 and the third plate 3213 at the same time, so as to trigger the three elastic cantilevers 11;
when the volume of the characteristic fluid in the housing chamber exceeds 120ml (120 ml is the volume common to the first chamber 3101, the second chamber 3102, and the third chamber 3103), that is, when the first chamber 3101, the second chamber 3102, and the third chamber 3103 are all filled with the characteristic fluid, and a part of the characteristic fluid is housed in the fourth chamber 3104, the characteristic fluid may drop down from the through holes of the first plate 3211, the second plate 3212, the third plate 3213, and the fourth plate 3214 at the same time, thereby triggering the four elastic cantilevers 11.
In actual use, corresponding to the four conditions of accommodating the characteristic fluid, a precipitation level can be set for each condition, for example, when the elastic cantilever 11 is triggered by one, the precipitation amount is 0-20ml, and the weak precipitation level can be identified; when the elastic cantilever 11 is triggered by two, the precipitation amount is 20-60ml, and the normal precipitation level can be determined; when the elastic cantilever 11 is triggered three times, the precipitation amount is 60-120ml, and the precipitation level can be determined as strong precipitation level; when the elastic cantilever 11 is triggered to four times, the precipitation exceeds 120ml, and the precipitation level of heavy rain can be identified.
Of course, the structural form of the water blocking plate portion 32 is not limited, for example, in some embodiments, the water blocking plate portion 32 is a spiral arc plate spirally rising around the central axis of the water collecting housing 31 in the first direction; wherein the first direction is a direction from the second opening 312 toward the first opening 311.
Specifically, the spiral arc plate is provided with a plurality of through holes penetrating through the spiral arc plate along the extending direction of the spiral arc plate. The plurality of through holes are uniformly distributed along the extending direction of the spiral arc plate, and the plurality of through holes are sequentially arranged at intervals along the first direction.
Through the arrangement of the spiral arc plate, the structure of the water collecting unit is simplified, and the production difficulty is reduced.
In some embodiments, the piezoelectric power generation unit 10 further comprises a support frame 12 and a piezoelectric sensor 13; each elastic cantilever 11 comprises a first section 111 fixedly supported on the support frame 12 and a second section 112 extending from the first section 111 in a direction away from the support frame 12 and arranged in a suspending manner, wherein the second section 112 is arranged opposite to the through hole 301, namely, the second section 112 is used for receiving dripped characteristic fluid; the piezoelectric sensor 13 is respectively connected with the monitoring unit 20 and the plurality of elastic cantilevers 11, and the piezoelectric sensor 13 is used for sending a trigger signal to the monitoring unit 20 when at least one elastic cantilever 11 is triggered, wherein the trigger signal is used for representing the number information of the triggered elastic cantilevers 11; the monitoring unit 20 acquires the number information of the triggered elastic cantilevers 11 according to the trigger signal, determines precipitation level information matched with the number information of the triggered elastic cantilevers 11, and finally outputs the precipitation level information.
As shown in fig. 2 and 4-5, in some embodiments, the precipitation monitoring device 100 further includes an adjusting bracket 40, where the piezoelectric generating unit 10 is connected to the adjusting bracket 40, and the adjusting bracket 40 is used to adjust the distance between the elastic cantilever 11 and the through hole 301.

By adjusting the setting of the support 40, the falling distance of the characteristic fluid from the through hole 301 to the elastic cantilever 11 can be effectively changed, so that the kinetic energy accumulation of the characteristic fluid in the process of falling is changed, and the vibration of the elastic cantilever 11 is affected to adjust the power generation.

Through the arrangement of the housing 50, the piezoelectric power generation unit 10 can be stored in the housing 50, that is, the housing 50 separates the piezoelectric power generation unit 10 from the external environment, so that the phenomenon that the elastic cantilever 11 is triggered by mistake due to the fact that wind in the external environment blows the elastic cantilever 11 or rainwater in the external environment drops on the elastic cantilever 11 to vibrate the elastic cantilever 11 is effectively avoided, the monitoring accuracy of the monitoring unit 20 is further improved, and the monitoring reliability is guaranteed.
