[0043] As a preferred embodiment, the guide member 4 is provided with an inner hole. The cross-section of the guide member 4 is polygonal. On the end surfaces where the sides of the outer peripheral surface of the guide member 4 are located, guide protrusions 41 are sequentially and alternately arranged along the axial direction. The lengths of the guide protrusions 41 on each side correspond to different water depth strokes one by one.

[0044] As a preferred embodiment, the water sample collector 3 overlaps on the heavy anchor base 2 and includes a main body member 31 and a movable switch 32;

[0045] The main body member 31 is provided with a floating plate 36 and a lock hole 37, and a central hole 33 is provided in its center. The shape of the central hole 33 is polygonal and adapted to the cross-sectional shape of the guide member 4.

[0047] As a preferred embodiment, the heavy anchor base 2 includes a hook connection mechanism 5 and a guide chute 21;

[0048] The guide chute 21 is located on the heavy anchor base 2 corresponding to the position of the lock hole 37 of the water sample collector 3;

[0049] The hook connection mechanism 5 is located on the guide chute 21; the hook connection mechanism 5 includes a lifting rod 51, a clamping member 52, a sliding base 53, a driving spring 54 and an electromagnetic plug-in component 55; the lifting rod 51 is arranged on the sliding base 53 and passes through the lock hole 37 to be connected with the clamping member 52 for restricting the floating of the main body member 31; the sliding base 53 is arranged on the guide chute 21 for radial sliding fit; the driving spring 54 is compressively arranged on the side of the sliding base 53 away from the central hole 33 for driving the clamping member 52 to move towards the center to engage with the lock hole 37 to restrict the floating of the main body member 31; the electromagnetic plug-in component 55 is arranged on the side of the sliding base 53 close to the central hole 33 for pushing the sliding base 53 away from the central hole 33 to drive the clamping member 52 to disengage from the lock hole 37.

[0050] As a preferred embodiment, the lifting rod 51 includes a support rod and a sleeve, and a plurality of positioning holes are axially arranged corresponding to the support rod and the sleeve, and the length of the sleeve and the support rod is fixed by screws.

[0051] Specifically, the heights of the overlapping main body members 31 are different. By setting the heights of different lifting rods 51 to lock different layers of the main body members 31, the corresponding electromagnetic plug-in components 55 can be controlled to make the corresponding water sample collectors 3 float.

[0052] As a preferred embodiment, the closed end 322 of the movable switch 32 is provided with a sealing plug 323 that is clamped with the water storage hole 34.

[0053] As a preferred embodiment, a plurality of hydrological information sensors are arranged on the heavy anchor base 2.

[0054] For example, the operator sets different sensors according to different objective conditions such as the hydrological information and water area environment to be detected. Only a part of the sensors listed in this application are shown, and it is possible to replace different sensors according to needs.

[0055] As a preferred embodiment, the floating ball platform 1 connects the power line and data line to the coupling mechanism 5 through the inner hole of the guiding member 4 to control the coupling mechanism 5 to unlock the water sample collector 3 in sequence; the second microcontroller controls the start and stop of the electromagnetic plug assembly 55, so that the plug protruding from the electromagnetic plug assembly 55 pushes the sliding base 53 away from the central hole 33, driving the engaging member 52 to disengage from the locking hole 37; the hydrological information sensor includes a water level sensor, a turbidity sensor, a water temperature sensor and a rainfall sensor; the floating ball platform 1 is further provided with a Beidou positioning module.

[0056] Specifically, the power line and data line are connected to the heavy anchor base 2 through the inner hole provided by the guiding member 4, so that the second microcontroller at the floating ball platform 1 controls the start and stop of the electromagnetic plug assembly 55. The electromagnetic plug protrudes from the main body member 31, and is provided with a through hole and a sealing ring.

[0057] In specific implementation, through the provided polygonal guide 4, such as a hexagon, firstly, the polygon is used to restrict the rotation of the water sample collector 3 during floating, preventing the disruption of the collection sequence. Secondly, based on the number of sides of the polygon, the number of movable switches 32 and water storage holes 34 is set. On the end faces where the sides of the outer peripheral surface of the guide 4 are located, guiding protrusions 41 are successively and alternately arranged along the axial direction. The lengths of the guiding protrusions 41 on each side correspond to different water depth ranges, such that each guiding protrusion 41 corresponds to a water area at a certain depth. For example, the length of the first guiding protrusion 41 starting from the heavy anchor base 2 is 3 meters, which is the water area at a height of 3 meters from the riverbed. Then the second guiding protrusion 41 is arranged on another end face adjacent to the first guiding protrusion 41, and the second guiding protrusion 41 corresponds to the water area at a height of 3 - 6 meters from the riverbed. By using the alternating arrangement of the guiding protrusions 41, when water samples at different depths are required, the staff uses the Beidou short message module to remotely control the unlocking of the first water sample collector 3 directly above in the vertical direction with overlapping. The main body 31 of the water sample collector 3 is provided with a floating plate 36, and is connected to the heavy anchor base 2 with a weight greater than the sum of the buoyancies of the floating plates 36, thus sinking to the bottom of the riverbed. After the connecting mechanism 5 unlocks one water sample collector 3, the water sample collector 3 floats upward. During the upward floating process, the first guiding protrusion 41 contacts the main body 31, and the contact end of the movable switch 32 provided on the end face of the central hole 33 of the main body 31 corresponding to the first guiding protrusion 41 collides with the guiding protrusion 41 and flips, driving the closed end 322 away from the water storage hole 34. The water storage hole 34 is initially closed and empty at the bottom of the riverbed. After it is opened, the water in this layer of water area enters the water storage hole 34 and is collected. The main body 31 continues to move upward and leaves the first guiding protrusion 41, and encounters the adjacent second guiding protrusion 41. At this time, the first movable switch 32 loses the collision resistance of the first guiding protrusion 41, and under the action of the torsion spring, the closed end 322 re-closes the water storage hole 34 to prevent the water in another layer of water area from entering. And the movable switch 32 corresponding to the end face of the second guiding protrusion 41 is opened. By repeating this operation, as the water sample collector 3 floats upward, each water storage hole 34 of the main body 31 collects water samples from water areas at different depths. After each water sample collector 3 has collected samples at different time periods according to the program, the staff makes a one-time patrol to recover the water samples at each data collection point, then raises the heavy anchor base 2, reconnects and installs each water sample collector 3, and sinks it back to the river bottom for repeated detection. The guide 4 can be made of various materials and in various forms. For example, it can be made of a whole section of flexible rubber tube, which is straightened by the pulling forces at both ends of the heavy anchor base 2 and the floating ball platform 1. It can also be made of spliced pipe fittings, such as polygonal pipes, with threaded holes and threaded shafts respectively arranged at both ends for end-to-end splicing.

[0058] In addition, an intelligent hydrological monitoring method based on Beidou short message communication includes:

[0059] The microcontrollers of the respective data acquisition devices collect the real-time acquisition data of each sensor module, and integrate and send it to the data aggregation device through the LORA communication module;

[0060] The data aggregation device processes the received data, such as classifying and merging, according to the numbers, time, and location information of the respective data acquisition devices, and automatically encapsulates it into the standard transmission format specified by the Beidou short message communication protocol. Through the Beidou short message module, using the short message communication transmission technology of Beidou satellites, it conducts remote communication with Beidou satellites;

[0061] Beidou satellites forward the received data to the user terminal, which includes a mobile APP platform and a terminal data detection and management center;

[0062] The mobile APP platform sends the data to the personal user's mobile phone through the base station. The terminal data detection and management center and the personal user monitor the real-time status of each data acquisition device and issue instructions. Each data acquisition device receives the instructions, unlocks the corresponding water sample collector 3, and records and uploads the number, unlocking time, and water area information of the water sample collector 3.

[0063] Specifically, the microcontrollers of the respective data acquisition devices collect the real-time acquisition data of each sensor module, and integrate and send it to the data aggregation device through the LORA communication module; the data aggregation device processes the received data, such as classifying and merging, according to the numbers, time, and location information of the respective data acquisition devices, and automatically encapsulates it into the standard transmission format specified by the Beidou short message communication protocol.

Each data acquisition device receives the instructions, unlocks the corresponding water sample collector, and records and uploads the number, unlocking time, and water area information of the water sample collector, so as to realize the remote supervision and control of the data acquisition points by the data supervision center and personal users.

[0064] It should be noted that the second microcontroller of the data acquisition device only needs to collect the real-time acquisition data of the sensor module and integrate and send it to the data aggregation device. The water level sensor, turbidity sensor, temperature sensor, and rainfall sensor required for monitoring are embedded in the structure of each acquisition device, and a second LoRa communication module is installed on each acquisition device; the second microcontroller transmits the real-time data such as water level, temperature, turbidity, and rainfall in the current area collected through the second LoRa communication module to the data aggregation device. After classifying and merging the received data, the data aggregation device automatically packages it into the standard transmission format specified by the Beidou short message communication protocol, and through the Beidou short message module, uses the short message communication transmission technology of Beidou satellites to communicate remotely with Beidou satellites. Beidou satellites transmit the monitoring data to the terminal data monitoring and management center equipped with a Beidou short message module or the mobile App platform supporting Beidou short message communication, realizing the real-time data transmission between the monitoring point and the terminal.

[0065] In the present invention, a Beidou short message module of the model M201 of Yiwei Technology is selected. This module integrates the Radio Determination Satellite Service (RDSS) and the Radio Navigation Satellite System (RNSS), that is, the positioning and communication functions, and has the advantages of small size, high success rate of sending and receiving, and low power consumption.
