Description

Technical Field

[0001] The present invention relates to the field of groundwater monitoring in geological exploration and underground engineering construction, and in particular to an intelligent device for automatic groundwater monitoring and early warning. Background Art

[0002] Whether it is building a house, or building roads, railways, bridges, tunnels and other projects, geological survey work is indispensable and is also the basic basis for the early environmental impact assessment, feasibility and design of various projects. Especially in the construction process of underground projects (including subways, tunnels, etc.), the basic information of groundwater in the area is required to be higher. At present, long-term observation holes in geological surveys are an effective way to effectively understand groundwater, and are also the most commonly used method. In cities, it is more convenient to observe due to convenient transportation, but in the field, due to transportation, complex surface environment, etc., long-term observation of observation holes is difficult. Sometimes, the observation holes cannot be found in time due to unclear markings, resulting in many problems such as untimely observation and unreliable data. In addition, during the construction of underground projects (such as subway station excavation, section tunneling, mountain tunneling, etc.), the impact of surrounding groundwater is very large. Changes in water quality and groundwater level are often closely related to the safety of the project. By observing the groundwater around the construction site, reliable guidance can be provided for safe construction. It can also provide first-hand information for effectively preventing uneven settlement of surrounding buildings due to the extraction of groundwater during construction in urban underground buildings. Summary of the invention

[0003] In order to solve the problems existing in the above-mentioned background technology, the monitoring and sampling of groundwater in geological exploration is made faster and more accurate, and the operation is efficient and standardized, and the quality of monitoring data is guaranteed. At the same time, the changes in groundwater level, water quality, flow direction, and water temperature are monitored and warned in time to provide first-hand information to ensure construction safety. The present invention proposes a simple and reasonable structural design, convenient operation and use, which can solve the problems of monitoring observation holes, difficulty in multiple sampling, low efficiency, etc. in geological exploration and construction, can greatly improve the efficiency of observation, ensure the reliability of sampling samples, and timely warning of groundwater during construction, while saving a lot of manpower, effectively reducing the monitoring cost, and having important application prospects and practical significance. The intelligent monitoring device for automatic monitoring, sampling, and early warning of groundwater.

[0004] The present invention adopts the following technical solutions to solve the above technical problems:

[0005] The structure of the above-mentioned intelligent monitoring device for automatic groundwater monitoring, sampling and early warning includes: data storage and control module, data transmission and connection module, and measurement unit module. The data storage and control module stores, analyzes and judges the data, and promptly alarms abnormal situations, while providing power for the entire measurement system; the measurement unit module measures the water temperature, TDS, pH value, flow rate, flow direction, etc. in the observation hole; the data transmission and connection module plays the role of connection and data transmission.

[0006] The data storage waterproof solar panel (101) and the retractable solar panel (102) of the intelligent monitoring device for automatic groundwater monitoring, detection and early warning convert solar energy into electrical energy and store it in the storage battery (104), thereby ensuring the long-term operation of the entire system. The telescopic solar panel (102) can adjust the height and direction, and can also provide sufficient electricity in places with dense bushes; the measurement data is first transmitted to the data receiving storage unit (108) through the data transmission and connection belt (201), and then transmitted to the data analysis unit (107) after processing and classification, and then the analysis result is fed back to the alarm unit (106), and a judgment is made on whether to alarm based on the set parameters. When the water level alarm (202) is disconnected, a water level alarm instruction is sent to the alarm unit (106); when the flow rate, flow direction, temperature, conductivity, TDS, and salinity of the groundwater exceed the set threshold, flow rate, flow direction, temperature, and water quality alarm instructions are sent to the alarm unit (106) respectively; the control interface (105) can set various parameters and the data copy interface, and display them on the display screen (103).

[0007] The data transmission and connection module (B) of the intelligent monitoring device for automatic monitoring, detection and early warning of groundwater is composed of a data transmission and connection belt (201) and a water level alarm (202). The data transmission and connection belt (201) is composed of a protective layer (2011) and a data signal line (2012). The water level alarm (202) is installed at a certain position of the data transmission and connection belt (201) according to the monitoring needs. The measurement information of the measurement unit module (C) is transmitted to the data receiving storage unit (108) through the data transmission and connection belt (201). When the water level is lower than the water level alarm (202), the float (3011) drops with the water level, driving the movable guide (3013) to drop and separate from the fixed guide (3014), causing the circuit to be broken and triggering the minimum liquid level alarm. The data transmission and connection belt (201) is provided with a water level alarm device interface (214) at a certain interval, and is used to install a water level alarm (202) according to actual needs. The water level alarm device interface (2014) has an electrode contact strip (215) inside, which is connected to the wire of the water level alarm (202) to transmit water level information to the surface data receiving storage unit (108). When the water level alarm device interface (2014) is not in use, the spring (20142) is in a slightly compressed state, so that the two clips (20140) are tightly closed, and the high elastic rubber sealing ring (20141) plays a close contact with the two contact surfaces to enhance the waterproof performance; when the water level alarm (202) needs to be connected, the limit bolt (20145) is pulled, and the nylon line (20143) compresses the spring (20142) through the pulley (20144) to move the clip (20140) upward, and the fixed end (3016) of the water level alarm (202) is inserted, and at the same time, the fixed clip ring (3015) and the data transmission and connection belt (201) are firmly tied to fix the water level alarm (202).

[0008] The protective layer (2011) of the measuring unit module (C) of the intelligent monitoring device for automatic monitoring, detection and early warning of groundwater plays a role in protecting internal parts; the rotating shaft (3037) of the water flow meter (303) is connected by double tenons, and the contact points are covered with steel balls (3035) to reduce the friction resistance of the contact surface, so that the water flow meter (303) can change direction under the action of a small force, driving the flow meter (3036) to change with the direction of the water flow; the movable electrode connector (30363) at the bottom of the rotating shaft is connected to the movable electrode connector (30363) of the flow meter (3036) through a wire (30364), and the flow meter (3036) rotates with the rotating shaft (3037); under the magnetic attraction of the permanent magnet (30361), the flow meter (3036) contacts with the contact conductor (30362) to form a circuit, and displays the position in real time. According to the change in position, the change in the real-time water flow direction can be obtained. The turbine (30311) of the flow meter (3031) rotates with the water flow. When the water flow speed is large, the rotation speed of the turbine (30311) also increases accordingly, resulting in a decrease in the collision time between the fixed rivet (303121) and the movable electrode rivet (303122). Therefore, the flow rate can be obtained by recording the number of collisions between the two rivets within a certain period of time. When the fixed rivet (303121) collides with the movable electrode rivet (303122), the conductor spring (303125) is compressed to drive the conical wear-resistant contact (303126) to move upward and contact with the electrode plate (303127), forming a loop to generate an electrical signal, and the amplifier (3034) amplifies the signal and transmits it to the data receiving storage unit (108). The thermometer (304) measures the temperature of the groundwater in real time and transmits the corresponding value to the data receiving storage unit (108) for storage and for use by the data analysis unit (107); the pH value of the groundwater measured by the pH meter (305) is transmitted to the data receiving storage unit (108) for storage and for use by the data analysis unit (107); and the water quality meter (306) transmits the data of the conductivity, TDS, salinity, etc. of the groundwater to the data receiving storage unit (108) for storage and for use by the data analysis unit (107).
