[0002] Sampling, also known as sampling, refers to the process of converting continuous quantities in the time domain or space domain into discrete quantities. At present, sampling operations exist in various fields. For example, for rainwater sampling, the rainfall over a period of time is collected and the rainwater samples are analyzed to obtain the rainfall or the substance content in the rainwater. A rainwater sampling device is required for sampling.

[0003] Although there are many kinds of sampling devices available, there are still some problems. For example, when conducting emergency rainwater sampling in areas affected by sudden disasters, the device needs to be placed in a rainwater environment and collect samples for a certain period of time to complete the sample collection. During the sample collection process, it is often necessary to control the amount of sample collected. However, since the amount of rainwater cannot be controlled, the collection time is also uncontrollable when the predetermined amount is collected. At present, the collection port of the rainwater collection device is in an open state during collection, which requires manual real-time observation of the amount of rainwater collected during collection. The operation is cumbersome, time-consuming and labor-intensive. Utility Model Content

The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The present invention provides a rainwater emergency sampling device based on Beidou communication. Figure 1-6 As shown, it includes: a collection box 1, a water collection chamber 2, a cover plate 3, a flow guide mechanism 4 and a water collection bucket 5;

[0028] The water collecting chamber 2 is concavely arranged at the top of the collection box 1, and the water collecting chamber 2 is a cylindrical structure. The cover plate 3 is placed on the top of the water collecting chamber 2, the diversion mechanism 4 is arranged at the bottom of the cover plate 3, and the water collecting bucket 5 is connected to the top of the cover plate 3;

[0029] The diversion mechanism 4 includes a diversion pipe 41, a linkage rod 42, an isolation plate 43, a driven rod 44 and a transmission unit. A through hole is provided on the cover plate 3. One end of the diversion pipe 41 is fixed in the through hole on the cover plate 3, and the other end is located at the bottom of the cover plate 3. The water collecting bucket 5 is plugged into the top of the diversion pipe 41. The linkage rod 42 is rotatably connected to the bottom of the side wall of the diversion pipe 41. The isolation plate 43 is fixed on the linkage rod 42. When the water level in the water collecting chamber 2 reaches a predetermined amount, the isolation plate 43 is tightly attached to the bottom end of the diversion pipe 41. One end of the driven rod 44 is rotatably connected to the center of the linkage rod 42.

[0030] The transmission unit is connected to the flow guide tube 41 , and is partially connected to the driven rod 44 .

[0031] It should be noted that in the current process of sample collection, it is often necessary to control the amount of samples collected. However, since the size of rainwater cannot be controlled, the collection time is uncontrollable when the predetermined amount is collected. At present, when the rainwater collection device is collecting, its collection port is in an open state, which leads to the need for manual real-time observation of the amount of rainwater collected during collection. The operation is cumbersome and time-consuming. To solve this problem, a diversion mechanism 4 is set in this solution. The rainwater is collected into the water collection cavity 2 through the diversion mechanism 4. Before collection, the gravity of the transmission unit drives the linkage of each part, so that the isolation plate 43 and the diversion pipe 41 are in a separated state, thus ensuring that the diversion pipe 41 is unobstructed. During collection, the buoyancy of the rainwater drives the synchronous linkage of the transmission unit, and then the driven rod 44 is driven to link through the transmission unit. The driven rod 44 pushes the linkage rod 42 to rotate on the linkage rod 42, and synchronously drives the isolation plate 43 to link until the isolation plate 43 fits against the bottom of the diversion pipe 41, isolating the bottom port of the diversion pipe 41 to avoid continuous collection. Through the setting of the diversion mechanism 4, the device can set the collection amount in advance when collecting rainwater. When the sample reaches the predetermined amount, the diversion mechanism 4 can automatically close and stop collecting, avoiding the need for frequent manual observation and adjustment. The operation is simple and efficient, saving time and effort.

[0032] Specifically, in this embodiment, this solution mainly includes a collection box 1, a water collection cavity 2, a cover plate 3, a diversion mechanism 4 and a water collection hopper 5. When in use, first place the collection box 1 in an appropriate position. At this time, the isolation plate 43 and the diversion pipe 41 are separated, and the rainwater flows into the diversion pipe 41 through the water collection hopper 5, and then flows into the water collection cavity 2 for collection operations. During collection, as the water level line rises, the floating ball 49 rotates the transmission seat 46 through the connecting rod 48 under the action of buoyancy, and then drives the driven rod 44 and the driving rod 45 to synchronously link. The driven rod 44 drives the linkage rod 42 to rotate until the isolation plate 43 is closely attached to the diversion pipe 41, and the diversion pipe 41 can be closed to stop collection.

[0033] In a further preferred embodiment of the present utility model, as Figure 1-6 shown, the transmission unit includes a driving rod 45, a transmission seat 46 and a fixed seat 47. The transmission seat 46 has a U-shaped structure, and a rectangular rod is fixed at the center of one side of the transmission seat 46. The fixed seat 47 is fixed at the bottom of the horizontal plate on the side wall of the diversion pipe 41, and the center of the rectangular rod of the transmission seat 46 is rotatably connected in the fixed seat 47. One end of the driving rod 45 is rotatably connected to one end of the transmission seat 46 through a rotating rod, and the other end of the driving rod 45 is rotatably connected to the top end of the driven rod 44 through a ball head bearing.

[0034] In this embodiment, the rotation of the transmission seat 46 drives the active rod 45 to be linked, and the active rod 45 drives the driven rod 44 to be linked, so that the linkage rod 42 and the isolation plate 43 can be rotated as a whole through the driven rod 44.

[0035] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the transmission unit further includes a connecting rod 48 and a floating ball 49 . The top of the connecting rod 48 is connected to one end of the rectangular rod of the transmission seat 46 , and the floating ball 49 is fixed to the bottom end of the connecting rod 48 .

[0036] In this embodiment, the buoyancy of the float 49 drives the connecting rod 48 to move in conjunction, thereby driving the transmission seat 46 and various parts to move in conjunction.

[0037] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the connecting rod 48 is composed of two telescopically adjustable rectangular rods to form an integral structure, and the two rectangular rods are locked by screws.

[0038] In this embodiment, the amount of rainwater collected is controlled by adjusting the length of the connecting rod 48 .

[0039] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the float 49 is made of stainless steel to form a spherical structure, and the interior of the float 49 is hollow and has buoyancy.

[0040] In this embodiment, the stainless steel material is used to prevent the float 49 from rusting, and at the same time, the float 49 has a certain gravity, so that the float 49 can pull the transmission seat 46 to rotate through its own gravity, thereby allowing the isolation plate 43 to be in a separated state from the guide tube 41 before collection.

[0041] In a further preferred embodiment of the present invention, Figure 1-6 As shown, an annular sealing gasket 6 is fixed at the bottom edge of the cover plate 3, and an annular docking groove 7 is provided on the upper surface of the collection box 1, and the docking groove 7 and the water collection chamber 2 are located on the same axis, and the sealing gasket 6 is clamped in the docking groove 7.

[0042] In this embodiment, the cover plate 3 and the collection box 1 are sealed by a sealing gasket 6 to prevent rainwater from flowing into the water collection chamber 2 through the gap between the cover plate 3 and the collection box 1 .

[0043] In a further preferred embodiment of the present invention, Figure 1-6 As shown, a support rod 8 is connected to the bottom of the collection box 1. The angle between the support rod 8 and the collection box 1 is adjustable, and the length of the support rod 8 is telescopically adjustable.

[0044] In this embodiment, by adjusting the length and angle of the support rod 8, the collection box 1 can be placed in an appropriate position to collect rainwater.

[0045] In a further preferred embodiment of the present invention, Figure 1-6 As shown, the collection box 1 is provided with an MCU controller, an LCD display, a power module, a controlled power output, a charging interface, a USB or TF card interface, a SUB-1GHZ or Lora module interface, an RS485 / SDI12 collection interface, a single / double-spring rain gauge interface, an NB-IoT / 4G / 5G module interface, a low-power Bluetooth module, an Ethernet module, a Wi-Fi module, an RS232 / RS485 communication serial port, a switch input, a switch output, an analog input and a low-orbit satellite communication interface component, and is developed based on new technologies of the Internet of Things, Beidou satellites, low-orbit satellites and 5G communications.

[0046] In this embodiment, through the application of multiple components and new technologies, the device can still use Beidou satellites to collect and transmit water condition data when ground communication facilities are damaged due to sudden disasters. In places where Beidou satellites are interfered with or communication conditions are poor, the deployment of low-orbit communication satellites will further improve the reliability of water condition data transmission in emergency situations.
