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 is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application 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 generating unit 10 comprises at least two elastic cantilevers 11, each elastic cantilever 11 is triggered when receiving a characteristic fluid dropped, and the piezoelectric generating unit 10 is used for converting kinetic energy generated when each elastic cantilever 11 is triggered into electric energy.
Specifically, when the characteristic fluid falls on the piezoelectric structure of the piezoelectric power generation unit 10, the characteristic fluid impacts the piezoelectric structure and vibrates the piezoelectric structure, and the piezoelectric power generation unit 10 can convert kinetic energy generated when the characteristic fluid falls into electric energy by using a 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 configured to receive a dropped characteristic fluid, the elastic cantilever 11 promotes itself to generate elastic vibration under impact of the dropped characteristic fluid, the impact process is actually a process of energy conversion, specifically, when the dropped characteristic fluid is received, the elastic cantilever 11 converts kinetic energy and potential energy of the dropped characteristic fluid into kinetic energy to promote itself to generate elastic vibration, and the elastic cantilever 11 generating the elastic vibration is considered to be in a triggered state, when the elastic cantilever 11 is triggered, the piezoelectric power generation unit 10 generates a piezoelectric effect under the elastic vibration of the elastic cantilever 11 to convert the kinetic energy of the elastic vibration of the elastic cantilever 11 into electric energy, thereby implementing a function of autonomous power generation through the piezoelectric effect.
It is worth mentioning 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 condition, since in nature, precipitation is a common natural phenomenon, and the precipitation process contains a large amount of energy, which is represented by kinetic energy and potential energy when the rainwater falls, and here, the characteristic fluid that drips is the rainwater that drips.
The structure of the elastic cantilever 11 is not limited, for example, in some embodiments, the elastic cantilever 11 is a piezoelectric sheet, and in this case, the piezoelectric sheet directly acts as a piezoelectric structure of the piezoelectric power generating unit 10, which can induce a piezoelectric effect in case of vibration. Of course, in other embodiments, the elastic cantilever 11 may also be used as a structure connected to the piezoelectric structure of the piezoelectric power generating unit 10, and in this case, the kinetic energy generated when the elastic cantilever 11 is triggered may be used to trigger the piezoelectric structure of the piezoelectric power generating unit 10 to generate the piezoelectric effect.
In addition, the number of the elastic cantilevers 11 is not limited, for example, in some embodiments, the elastic cantilevers 11 include four and are spaced apart from each other.
And the monitoring unit 20 is connected with the piezoelectric power generation unit 10 and used for generating precipitation level information according to the number of the triggered elastic cantilevers 11 under the driving of electric energy. The precipitation level information and the number of the triggered elastic cantilevers 11 are set in a correlated manner, a plurality of precipitation level information needs to be set in advance before the precipitation monitoring device 100 monitors precipitation, and different level information corresponds to the triggered number of the different elastic cantilevers 11 respectively. For example, in some embodiments, when four elastic cantilevers 11 are provided, four pieces of precipitation level information are preset to be associated with the case when the number of the triggered elastic cantilevers 11 is one, two, three, and four, respectively.
In the above-mentioned precipitation monitoring device 100, the elastic cantilevers 11 of the piezoelectric power generating unit 10 receive the characteristic fluid that drops, each elastic cantilever 11 converts the kinetic energy and potential energy of the characteristic fluid when dropping into the kinetic energy of its own elastic vibration, thereby promoting the piezoelectric power generation unit 10 to generate piezoelectric effect to obtain electric energy, the monitoring unit 20 can utilize the electric energy of the part to detect precipitation, because the electric energy is generated by the piezoelectric power generation unit 10, the rainfall monitoring device 100 can provide electric energy for itself without an additional external power supply, thereby effectively ensuring that the rainfall monitoring device 100 can normally monitor rainfall, meanwhile, the monitoring unit 20 can also directly generate precipitation grade information according to the number of the triggered elastic cantilevers 11, so that precipitation monitoring work is completed in real time and rapidly, and the precipitation monitoring efficiency is improved.
In some embodiments, the precipitation monitoring device 100 further comprises a water collection unit 30 having a housing 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 respectively penetrating through the water collecting unit, the through holes 301 are respectively arranged opposite to the elastic cantilevers 11 at intervals, and each through hole 301 is used for guiding the characteristic fluid in the accommodating cavity 310 to drip towards the corresponding elastic cantilever 11.
In some embodiments, the water collecting unit 30 includes a water collecting case 31 and a water blocking baffle portion 32. Wherein:
the water-blocking baffle 32 is fixed inside the water collection shell 31, forms a housing cavity 310 together with the water collection shell 31, and the through holes 301 are provided through the water-blocking baffle 32.
Specifically, the water collecting shell 31 is provided with a first opening 311 and a second opening 312 which are oppositely arranged at 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 allow the characteristic fluid to flow into the containing cavity 310 to collect the characteristic fluid; the second opening 312 is located on a side close to the piezoelectric power generating element 10 and is disposed toward the piezoelectric power generating element 10, and the second opening 312 allows the characteristic fluid flowing out from the through hole 301 to drip toward the elastic cantilever 11.
The water-blocking baffle portion 32 includes at least two step plates 321 sequentially arranged at intervals along a first direction (i.e., an X-axis direction, which is a direction from the second opening 312 toward the first opening 311), and side walls 322 respectively connecting the two adjacent step plates 321, and each step plate 321 is provided with a through hole 301 through; it should be noted that the plurality of step plates 321 and the side wall 322 together divide the receiving cavity 310 into a plurality of sub-receiving cavities, and each sub-receiving cavity correspondingly receives characteristic fluids with different capacities.
It is worth mentioning that the distribution mode of the plurality of step plates 321 can be adjusted according to the requirement of the actual design, and considering that the plurality of through holes 301 are too densely arranged, the arrangement of the elastic cantilevers 11 is too concentrated, which easily causes the phenomenon that the adjacent two elastic cantilevers 11 interfere with each other to cause the false triggering of a part of the elastic cantilevers 11, therefore, in some embodiments, the plurality of step plates 321 are uniformly distributed around the central axis of the water collecting shell 31, so that 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 plurality of elastic cantilevers 11 are reasonably distributed, and the reasonable distance interval can be provided between the adjacent two elastic cantilevers 11, thereby avoiding the false triggering phenomenon caused by the vibration interference between the adjacent two elastic cantilevers 11, the monitoring accuracy can be improved, and the monitoring reliability can be ensured.
For example, in some embodiments, the step 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 the 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, 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 together form a 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 capacities, and the receiving capacity of the characteristic fluid corresponding to each sub-receiving cavity can be specifically set according to the actual use requirement, for example, in some embodiments, the capacity of the first cavity 3101 is 20ml, the capacity of the second cavity 3102 is 40ml, the capacity of the third cavity 3103 is 60ml, and the capacity of the fourth cavity 3104 is greater than 80ml, which needs to be further described as follows:
when the volume of the characteristic fluid in the containing 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 containing cavity is 20-60ml (60 ml is the common volume of the first cavity 3101 and the second cavity 3102), the characteristic fluid can simultaneously drop down from the through holes of the first plate 3211 and the second plate 3212, so as to trigger the two elastic cantilevers 11;
when the volume of the characteristic fluid in the containing cavity is 60-120ml (120 ml is the common volume of the first cavity 3101, the second cavity 3102 and the third cavity 3103), the characteristic fluid can simultaneously drop downwards from the through holes of the first plate 3211, the second plate 3212 and the third plate 3213, so as to trigger the three elastic cantilevers 11;
when the volume of the characteristic fluid in the containing cavity exceeds 120ml (120 ml is the common capacity of the first cavity 3101, the second cavity 3102 and the third cavity 3103), that is, when the first cavity 3101, the second cavity 3102 and the third cavity 3103 are all filled with the characteristic fluid and part of the characteristic fluid is contained in the fourth cavity 3104, the characteristic fluid can simultaneously drop down from the through holes of the first plate 3211, the second plate 3212, the third plate 3213 and the fourth plate 3214, thereby triggering the four elastic cantilevers 11.
In practical use, corresponding to the above four cases of containing the characteristic fluid, a precipitation level may be set for each case, for example, when the elastic cantilever 11 is triggered, the precipitation amount is 0-20ml, and may be regarded as a weak precipitation level; when the two elastic cantilevers 11 are triggered, the precipitation amount is 20-60ml, and the normal precipitation level can be determined; when the three elastic cantilevers 11 are triggered, the precipitation amount is 60-120ml, and the precipitation level can be regarded as strong precipitation level; when four resilient cantilevers 11 are activated, precipitation exceeding 120ml is considered as a rainstorm precipitation level.
Of course, the structure of the water stop plate 32 is not limited, for example, in some embodiments, the water stop plate 32 is a spiral arc plate that is spirally raised around the central axis of the water collecting shell 31 in the first direction; the first direction is a direction from the second opening 312 to the first opening 311.
Specifically, a plurality of through holes penetrating through the spiral arc plate are formed in the spiral arc plate along the extending direction of the spiral arc plate. Wherein, a plurality of through-holes set up along the extending direction evenly distributed of spiral arc board, and a plurality of through-holes set up along first direction interval in proper order.
