Description

Technical Field

[0001] This utility model relates to the field of river transport testing technology, specifically to a river transport time tracing test device. Background Technology

[0002] River transport refers to the natural process by which rivers carry and transport sediments (such as silt, gravel, etc.) and dissolved substances from upstream to downstream or along the banks through hydrodynamics. This is an important mechanism in the evolution of river landforms.

[0003] Currently, some river transport testing devices adopt a floating design, which facilitates users to conduct high-precision hydrological measurements. However, such devices have significant sealing defects in practical applications: when the device operates in an aquatic environment for a long time, if the waterproof structure fails and water enters the interior, it will directly cause short-circuit damage to the device's core electronic components (such as sensors, data acquisition modules, etc.), seriously affecting the accuracy of the test data and the reliability of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a river transport time tracer test device, which aims to solve the problem that the existing river transport devices have poor sealing performance, which can lead to water ingress.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the river transport time tracer experimental device includes an upper shell and a lower shell, which are fixedly connected by bolts. The upper shell and the lower shell are spliced ​​together to form a cavity structure. The cavity structure is equipped with an information component and a battery that supplies power to the information component. A waterproof component is provided at the joint between the upper and lower shells to achieve a waterproof seal for the cavity structure. The upper and lower shells are spliced ​​together to form a floating ball structure. The floating ball structure is placed in the river so that the collected data can be transmitted to the cloud server through the information component.

[0006] Preferably, the waterproof component includes a slot ring disposed on the upper housing with its opening facing downward, an L-shaped insert ring fixed on the lower housing and extending in the vertical direction, and a first circular rubber pad disposed between the upper housing and the lower housing. After the L-shaped insert ring is inserted into the slot ring, the sealing between the L-shaped insert ring and the slot ring can be improved by the first waterproof component.

[0007] Preferably, the first waterproof component includes a side waterproof strip fixed to the outside of the L-shaped insertion ring and extending in the vertical direction, a first top waterproof strip fixed to the top of the L-shaped insertion ring, and a second top waterproof strip fixed to the inner top wall of the slot ring. After the L-shaped insert ring is inserted into the slot ring, the side waterproof strip can abut against the inner wall of the slot ring, and the first and second top waterproof strips are tightly attached.

[0008] Preferably, the waterproof component includes a second annular rubber gasket disposed between the upper housing and the lower housing.

[0009] Preferably, an upper ring plate is fixed on the side of the upper housing near the lower housing, and a lower ring plate is fixed on the side of the lower housing near the upper housing. Both the upper and lower ring plates have through holes, and the bolt passes through the two through holes to be threadedly connected to the fastener. The waterproof component is located between the upper and lower circular rings.

[0010] Preferably, the information component includes a circuit board assembly installed inside the upper housing, a communication module installed on the circuit board assembly, a GPS module installed on the circuit board assembly, and a controller module installed on the circuit board assembly; The battery is installed inside the lower casing; The communication module, GPS module, and controller module are all electrically connected to the circuit board assembly; The battery is electrically connected to the circuit board assembly, which is equipped with a charging socket, a power self-locking switch, and a reset switch.

[0011] Preferably, a mounting bracket is fixed on the inner top wall of the upper housing, and the circuit board assembly is mounted on the mounting bracket.

[0012] Preferably, the upper housing has a through hole that allows for both internal and external penetration; The charging socket, power self-locking switch, and reset switch are installed inside the through hole, and a plastic gasket is provided between the charging socket, power self-locking switch, and reset switch and the through hole.

[0013] The beneficial effects are: 1. The device adopts a waterproof and sealed structure design, forming a sealed cavity through the assembly of the upper and lower shells. During assembly, the waterproof components form a protective barrier, which not only significantly improves the overall sealing performance of the cavity structure, but its redundant design also more effectively protects the internal electronic components from moisture corrosion.

[0014] 2. Through the splicing structure of the upper and lower shells, and with the dynamic balancing effect of the bottom battery, the device maintains a stable posture with the lower shell facing downwards in water, its working principle being similar to the self-recovering characteristic of a roly-poly toy. This innovative structure has three advantages: First, the gravity self-stabilization mechanism effectively prevents key interfaces such as the charging socket, power self-locking switch, and reset switch on the upper shell from contacting the water; second, placing the circuit board assembly in the upper dry area avoids moisture corrosion and improves the quality of wireless signal transmission; third, the unique hydrodynamic shape design allows the device to maintain vertical stability even in turbulent environments, greatly improving the reliability and data accuracy of the equipment in water quality monitoring.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] Example 1, a river transport time tracing experimental device, is mainly used for measuring the transport time of floating objects in relatively straight river channels after the upper shell 1 and lower shell 2 are assembled. It can also be used for preliminary measurement of the transport time of floating objects and dissolved pollutants in other types of natural rivers. When the device is drifting in the river, it can upload data to a server (Tencent Cloud). The uploaded data includes: M2M ICCID, battery voltage, number of visible satellites, effective status, number of satellites used, positioning status, positioning mode, positioning accuracy (horizontal accuracy factor, vertical accuracy factor, position accuracy factor), UTC date, UTC month, UTC year, UTC hour, UTC minute, UTC second, Beijing time date and time, latitude, longitude, speed, and true north heading. This data is stored in an SQLITE database on the cloud server, and the data is later extracted and downloaded for transport time calculation.

[0019] like Figures 1-3 and Figure 5 As shown, in this embodiment, the simulation device includes an upper housing 1 and a lower housing 2, which are fixedly connected by bolts 8. The upper housing 1 and the lower housing 2 are spliced ​​together to form a cavity structure. The cavity structure contains an information component and a battery 3 that supplies power to the information component. The cavity structure protects the information component and the battery 3 from water during use. The battery 3 is a 312V 15000mAh-XH2.543 series 3 parallel 21700 battery pack, which has a continuous working time of approximately 140 hours and transmits a set of data every 36 seconds.

[0020] The floating sphere structure, formed by the upper shell 1 and the lower shell 2, is placed in the river to transmit the collected data to the cloud server via an information component. In this embodiment, the river transport time tracer experimental device consists of two parts: a cloud server and the floating sphere structure. The cloud server consists of a hard disk, an operating system, data receiving and storage, and data extraction programs. The hard disk and operating system on the cloud server side are rented from the operator, while the relevant programs are self-developed. The floating sphere structure consists of two parts: hardware and software. The hardware consists of the upper shell 1 and the lower shell 2, a circuit board assembly 601, a power self-locking switch 16 and a reset switch 17, a charging socket 15, and a battery 3. The software is self-developed.

[0021] In this embodiment, the upper housing 1 and the lower housing 2 are made of acrylic (plexiglass) domes and designed as a double-chamber structure. The cavity in which the battery 3 is placed is the battery chamber, and the cavity in which the information components are placed is the instrument chamber. The battery chamber and the instrument chamber are isolated and sealed with 2 mm thick acrylic plates and hot melt adhesive. The double-chamber structure helps to prevent water from seeping into the battery 3.

[0022] like Figure 2 and Figure 3As shown, the upper shell 1 and the lower shell 2 are spliced ​​together, and the cavity structure can be sealed by waterproof components to improve the waterproof effect.

[0023] Specifically, a waterproof component is provided at the joint between the upper housing 1 and the lower housing 2 to achieve a waterproof seal for the cavity structure. The waterproof component includes a slot ring 701 with its opening facing downward on the upper housing 1, an L-shaped insert ring 702 fixed on the lower housing 2 and extending in the vertical direction, and a first circular rubber gasket between the upper circular ring piece 22 and the lower circular ring piece 23. After the L-shaped insert ring 702 is inserted into the slot ring 701, the first waterproof component allows the L-shaped insert ring 702 to be inserted into the slot ring 701, thereby improving waterproofness and sealing.

[0024] The first waterproof component includes a side waterproof strip 9 fixed to the outside of the L-shaped insert ring 702 and extending in the vertical direction, a first top waterproof strip 10 fixed to the top of the L-shaped insert ring 702, and a second top waterproof strip 11 fixed to the inner top wall of the slot ring 701. After the L-shaped insert ring 702 is inserted into the slot ring 701, the side waterproof strip 9 can tightly abut against the inner wall of the slot ring 701 to prevent moisture from flowing between the side wall of the L-shaped insert ring 702 and the slot ring 701. When the L-shaped insert ring 702 is inserted to the top of the slot ring 701, the first top waterproof strip 10 and the second top waterproof strip 11 fit tightly together, which can seal the moisture flowing between the side wall of the L-shaped insert ring 702 and the slot ring 701 again. Through the sealing of the three parts, the sealing effect is greatly improved.

[0025] In this embodiment, the side waterproof strip 9, the first top waterproof strip 10, and the second top waterproof strip 11 are made of rubber. The structure and principle of rubber are existing technologies and will not be described in detail here.

[0026] like Figure 1 and Figure 2 As shown, an upper ring plate 22 is fixed on the side of the upper shell 1 near the lower shell 2, and a lower ring plate 23 is fixed on the side of the lower shell 2 near the outer upper shell 1. Both the upper ring plate 22 and the lower ring plate 23 have through holes. The bolt 8 passes through the two through holes and is threaded to the fastener. When the two ends of the bolt 8 are tightened with the fastener, the upper shell 1 and the lower shell 2 can squeeze the first ring gasket, thereby improving the waterproof performance of the waterproof component.

[0027] like Figure 2 and Figure 5 As shown, the information component is capable of transmitting data.

[0028] Specifically, the information components include a circuit board assembly 601 installed inside the upper housing 1, a communication module 602 installed on the circuit board assembly 601, a GPS module 603 installed on the circuit board assembly 601, and a controller module 604 installed on the circuit board assembly 601. In this embodiment, the circuit board assembly 601 with the floating ball structure adopts a 4-layer design, and the circuit mainly consists of three parts: the GPS module 603, the microcontroller (MCU), and the communication module 602. The GPS module 603, the microcontroller, and the communication module 602 are all domestically produced. Among them, the GPS module 603 uses the product model TAU1201-1216A00, the microcontroller uses the HC32F460JETA-LQFP48 chip, and the communication module 602 uses the product model WH-GM800TF-8-N41. The communication module 602 uses an OA-NO1 SMD patch antenna, and the GPS module 603 uses a CA-GO1 SMD patch antenna. Through impedance matching, the OA-NO1 SMD patch antenna works well at 2100 MHz, and the CA-GO1 SMD patch antenna works well at the L5 frequency. Testing showed that under cold start conditions, most PCBs could achieve GPS positioning within two minutes, demonstrating good performance. The battery 3 is installed inside the lower housing 2. The communication module 602, GPS module 603, and controller module 604 are all electrically connected to the circuit board assembly 601. The battery 3 is electrically connected to the circuit board assembly 601, which is electrically connected to a charging socket 15, a power self-locking switch 16, and a reset switch 17. The charging socket 15 can charge the battery 3. In this embodiment, the information component also includes a SIM card, which is an internal card (i.e., the internal card is integrated into the M2M module), but an external card can also be used preferentially (an external card is inserted into the SIM card slot on the PCB).

[0029] In this embodiment, the software part of the floating ball structure was developed in-house. The development environment was Keil MDK µvision 5.39.0.0, and the programming language was C. The MCU receives the positioning information from the GPS module 603 and sends it to the communication module 602. The communication module 602 uses the MQTT protocol to package the positioning data and send it to the cloud server.

[0030] like Figure 2 As shown, a mounting bracket 18 is fixed on the inner top wall of the upper housing 1, and the circuit board assembly 601 is mounted on the mounting bracket 18 to realize the installation of the circuit board assembly 601.

[0031] like Figure 1 and Figure 2As shown, the upper housing 1 has a through hole that allows for internal and external penetration; the charging socket 15, the power self-locking switch 16, and the reset switch 17 are installed inside the through hole. A plastic gasket is provided between the charging socket 15, the power self-locking switch 16, and the reset switch 17 and the through hole. In this embodiment, the structure and principle of the plastic gasket are prior art and will not be described in detail here. It can prevent moisture from flowing into the charging socket 15, the power self-locking switch 16, and the reset switch 17 and the through hole.

[0032] like Figure 2 As shown, the battery 3 is fixed on the inner bottom wall of the lower housing 2. In this embodiment, the battery 3 can be regarded as a counterweight structure, which enables the device to maintain the stable posture of the lower housing 2 facing downward, similar to a roly-poly structure, so that the lower housing 2 is always below the water surface.

[0033] Working principle: During use, the upper shell 1 and the lower shell 2 are assembled together. During the assembly process, after the L-shaped insert ring 702 is inserted into the slot ring 701, the sealing between the L-shaped insert ring 702 and the slot ring 701 is improved by the first waterproof component. Then, the bolt 8 is passed through the two through holes and threaded to the fastener, so that the upper ring piece 22 and the lower ring piece 23 are fixedly connected. After the upper shell 1 and the lower shell 2 are assembled, they can be placed in the river. This device is used to measure the transport time of floating objects in relatively straight river channels. It can also be used for the preliminary measurement of the transport time of floating objects and dissolved pollutants in other types of natural rivers. Afterwards, the device moves with the river. During the movement, the data can be packaged in JSON format and uploaded to the cloud server (Tencent Cloud) every 36 seconds. The uploaded data includes: M2M ICCID, battery voltage, number of visible satellites, valid status, number of satellites used, positioning status, positioning mode, positioning accuracy (horizontal accuracy factor, vertical accuracy factor, position accuracy factor), UTC date, UTC month, UTC year, UTC hour, UTC minute, UTC second, Beijing time, latitude, longitude, speed, and true north heading. This data is stored in an SQLITE database on Tencent Cloud servers and will be extracted and downloaded later for migration time calculation.

[0034] Example 2 is based on Example 1. The similarities between the two examples will not be repeated. The difference is that the waterproof component includes a second annular rubber pad disposed between the upper annular piece 22 and the lower annular piece 23. When the upper shell 1 and the lower shell 2 are assembled, it can achieve a waterproof effect. When making the floating ball structure, the upper annular piece 22, the lower annular piece 23 and the second annular rubber pad work together to meet the waterproof requirements and reduce the processing cost.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
