Description

Technical Field

[0001] This utility model relates to the field of monitoring devices, specifically to an online groundwater quality monitoring device. Background Technology

[0002] Groundwater is an important water resource. Establishing a groundwater quality monitoring system can promptly detect and monitor groundwater pollution, ensure groundwater safety, and provide scientific basis and decision support for water resource management, environmental protection, and disaster reduction.

[0003] Online monitoring of groundwater quality has at least the following shortcomings due to limitations imposed by site and environmental factors: traditional monitoring methods use extraction-based electrochemical analysis, which lacks real-time performance and flexibility; common monitoring devices require mains power and circuit installation; and the monitoring and analysis host is set up outdoors, where direct sunlight can easily accelerate the aging of electronic components. Utility Model Content

[0004] The technical problem to be solved by this invention is how to provide flexible power supply for an online groundwater quality monitoring device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An online groundwater quality monitoring device includes a monitoring and analysis host, a solar panel, a fixed bracket, and a combined in-situ probe. The fixed bracket is fixedly installed, the monitoring and analysis host is fixed to the upper end of the fixed bracket, the solar panel is fixedly connected to the fixed bracket and located above the monitoring and analysis host, the solar panel is electrically connected to the monitoring and analysis host, and the combined in-situ probe is located in a groundwater well and is communicatively connected to the monitoring and analysis host.

[0006] The beneficial effects of this invention are as follows: the combined in-situ probe can detect various parameters of groundwater in real time within a groundwater well and transmit the data to the monitoring and analysis host. The solar panel converts solar energy into electrical energy to power the monitoring and analysis host, which can flexibly choose between mains power or solar power depending on the site conditions. Simultaneously, the solar panel, installed above the monitoring and analysis host, can protect it from rain and sun, slowing down its aging process and increasing the lifespan of the online groundwater quality monitoring device.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, there are two solar panels, with one end of each solar panel facing each other inclined upwards.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the two solar panels are inverted V-shaped, which can guide rainwater or debris falling on them downwards, preventing rainwater and debris from accumulating on the solar panels and ensuring the normal use of the solar panels.

[0010] Furthermore, the groundwater quality online monitoring device also includes a battery and a battery power line. The solar panel is electrically connected to the battery, and the battery is electrically connected to the monitoring and analysis host through the battery power line.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the solar panel stores electrical energy in the battery, and the battery supplies power to the monitoring and analysis host through the battery power line.

[0012] Furthermore, the groundwater quality online monitoring device also includes a probe power data cable, and the combined in-situ probe is communicatively connected to the monitoring and analysis host through the probe power data cable.

[0013] The advantages of adopting the above-mentioned further solution are: the combined in-situ probe communicates with the monitoring and analysis host via the probe power data cable and transmits the detected data; compared with wireless transmission, the wired connection provides more stable and reliable data transmission. Simultaneously, the probe power data cable enables the monitoring and analysis host to supply power to the combined in-situ probe.

[0014] Furthermore, the groundwater quality online monitoring device also includes an explosion-proof housing, which is fixedly connected to the fixed bracket, and the monitoring and analysis host is installed inside the explosion-proof housing.

[0015] The advantage of adopting the above-mentioned further solution is that traditional monitoring devices do not consider the requirements for use in explosion-proof environments. This device is designed with an explosion-proof enclosure to ensure the stable operation of the monitoring and analysis host.

[0016] Furthermore, the groundwater quality online monitoring device also includes a pulley and a hanging rope. The pulley is rotatably mounted on the fixed bracket, and one end of the hanging rope is fixedly connected to the combined in-situ probe, while the other end passes around the pulley.

[0017] The advantages of adopting the above-mentioned further solution are as follows: the hanging rope, after passing over the pulley, connects to the combined in-situ probe, positioning and fixing the combined in-situ probe to ensure that the probe does not affect the well wall of the groundwater. It facilitates adjusting the lowering depth of the combined in-situ probe or lifting it via the hanging rope, thus facilitating equipment operation and maintenance. Simultaneously, the hanging rope provides tension to the combined in-situ probe, preventing the probe's power and data cables from bearing the weight of the combined in-situ probe.

[0018] Furthermore, the lower part of the fixed bracket has a crossbeam, and the pulley is rotatably mounted on the crossbeam.

[0019] Furthermore, the combined in-situ probe includes multiple sensing probes and a probe bracket, with the multiple sensing probes fixed inside the probe bracket and the multiple sensing probes respectively communicating with the monitoring and analysis host.

[0020] The beneficial effects of adopting the above-mentioned further scheme are: the combined in-situ probe has multiple sensing probes, and sensing probes equipped with different sensors can be set according to the analysis requirements. The detectable indicators include pH, temperature, conductivity, oil in water, water depth, ammonia nitrogen, and characteristic factors of organic matter in water.

[0021] Furthermore, the plurality of sensor probes are divided into at least two probe groups, and the at least two probe groups are arranged in sequence with partial overlap in the vertical direction. Each probe group includes at least two sensor probes arranged laterally at intervals. The sensor probes of adjacent probe groups are staggered circumferentially along the probe bracket.

[0022] The advantages of adopting the above-mentioned further solutions are: the sensor probes are installed in a stacked manner, resulting in a compact structure, reduced installation diameter, space saving, and ease of on-site installation.

[0023] Furthermore, the groundwater quality online monitoring device also includes a remote monitoring platform, and the monitoring and analysis host is communicatively connected to the remote monitoring platform.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the monitoring and analysis host remotely transmits the field data to the remote supervision platform, realizing remote monitoring and querying of various field monitoring data. Attached Figure Description

This allows for easy adjustment of the lowering depth of the combined in-situ probe 7 or its lifting via the hanging rope 9, facilitating equipment operation and maintenance. Simultaneously, the hanging rope 9 provides tension to the combined in-situ probe 7, preventing the probe's power data cable 6 from bearing the weight of the combined in-situ probe 7.

[0047] Specifically, the other end of the hanging rope 9 is connected to a rope winding and unwinding mechanism, such as a winch; or the other end of the hanging rope 9 is manually wound and unwound, and then the other end of the hanging rope 9 is detachably connected to the fixed bracket 3.
