[0030] Figure 1 A structural schematic diagram of a rainfall intensity calibration device according to an embodiment of the utility model is shown. Figure 2 The 3D perspective view of a rainfall intensity calibration device according to an embodiment of the present invention is shown. As shown in the figure, a rainfall intensity calibration device 100 mainly comprises a rainwater receiving barrel 101, a device barrel 102, a drainage pipe 103 and a weighing device 104.

[0031] The top of the rainwater receiving barrel 101 is opened. The rainwater receiving barrel 101 is used to receive rainwater.

[0032] The device barrel 102 is arranged below the rainwater receiving barrel 101. The device barrel 102 is connected to the bottom of the rainwater receiving barrel 101 through a pipeline 105, and the pipeline 105 penetrates downward into the device barrel 102. A functional device 106 and a switch valve 107 are arranged on the pipeline 105, and the functional device 106 is used to control the switch valve 107 to discharge the rainwater received by the rainwater receiving barrel 101.

[0033] One end of the drain pipe 103 is connected to the bottom of the pipeline 105, and the other end passes through the device barrel 102. The drain pipe 103 is used to discharge rainwater in the pipeline 105 to the outside of the device barrel 102.

[0034] The weighing device 104 is arranged at the bottom of the device barrel 102. The weighing device 104 is used to carry the device barrel 102 and the rainwater receiving barrel 101 and measure the rainfall. The weighing device 104 can choose to use a weighing system with different ranges to match the needs of rainfall simulation tests with different precisions and ranges.

[0035] Preferably, the weighing device 104 calculates the rainfall in real time according to the change of the bearing weight per unit time.

[0036] Preferably, the weighing device 104 includes a display screen and a wireless transmission device. The display screen is used to display the calculated rainfall. The weighing device 104 transmits the calculated rainfall to an external device via the wireless transmission device. As an example but not a limitation, the weighing device 104 may also include a memory for storing the calculated rainfall for subsequent calibration.

[0037] Preferably, if the rainwater receiving barrel 101 receives a set amount of rainwater, the functional device 106 opens the switch valve 107 to discharge the rainwater received by the rainwater receiving barrel 101. The rainwater receiving barrel 101 can set an upper limit of the amount of rain it carries. When the upper limit of rainwater is reached, the switch valve 107 is opened, and the rainwater enters the pipeline 105 from the rainwater receiving barrel 101 and is discharged to the outside of the rainfall intensity calibration device 100 through the drain pipe 103 to ensure the measurement accuracy and sustainability of the weighing device 104. It is easy to understand that when the rainwater in the rainwater receiving barrel 101 is emptied, the switch valve 107 is closed to continue the subsequent measurement.

[0038] Preferably, a sensor is provided on the inner wall of the rainwater receiving barrel 101 to detect the depth of rainwater. The functional device 106 determines whether the depth of rainwater reaches the upper limit of rainfall based on the signal received by the sensor, and if so, opens the switch valve 107 to discharge rainwater.

[0039] Optionally, the functional device 106 opens the switch valve 107 based on the weight of rain water measured by the weighing device 104. If the weight of rain water reaches the corresponding upper limit of rainfall, the weighing device transmits a signal to the functional device 106, and the functional device 106 triggers the switch valve 107 to open to discharge rain water.

[0040] Preferably, the rainwater receiving barrel 101 is cylindrical, and a round hole 108 is provided on the top thereof. The rainwater receiving barrel 101 receives rainwater through the round hole 108. The rainwater receiving barrel 101 is detachably arranged above the device barrel 102. When transporting the rainfall intensity calibration device 100, the rainwater receiving barrel 101 can be removed from the device barrel 102, transported separately, and assembled when arriving at the rainfall measurement point to avoid transportation damage, which may damage the device and make it impossible to measure.

[0041] Preferably, the device barrel 102 is cylindrical, and its cross-sectional area is the same as that of the rainwater receiving barrel 101 , so as to facilitate the centering assembly of the rainwater receiving barrel 101 and the device barrel 102 .

[0042] Preferably, the weighing device 104 is detachably disposed at the bottom of the device barrel 102. Similarly, when transporting the rainfall intensity calibration device 100, the weighing device 104 can be removed from the device barrel 102 and transported separately, and then assembled when arriving at the rainfall measurement point to further avoid transportation damage and ensure the device measurement effect.

[0043] Preferably, a support foot 109 is provided at the bottom of the weighing device 104 to form a stable support structure to ensure measurement stability.

[0044] The rainfall intensity calibration device provided by the utility model has the following advantages:

[0045] The overall structure is compact;

[0046] The rainwater receiving barrel, device barrel and weighing device are detachably assembled to reduce the transportation damage of the calibration device and better maintain the measurement accuracy;

[0047] It can continuously measure rainfall with a high degree of automation.

[0048] It will be apparent to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention covers modifications and variations of the present invention that fall within the scope of the appended claims and their equivalent technical solutions.
