An integrated soil and groundwater stratified monitoring module

Abstract

This utility model discloses an integrated soil and groundwater stratified monitoring module, which relates to the field of groundwater monitoring technology. A circular groove is fixedly installed at the center of the top of the manhole cover plate, and a rubber gasket is fixedly installed in the groove. A recess is formed on the top of the manhole cover plate. This integrated soil and groundwater stratified monitoring module, through the cooperation of the recess on the top of the manhole cover plate and the rubber gasket, utilizes the tight fit between the inner wall of the rubber gasket and the insulation layer of the cable to protect the cable and improve the sealing effect. During rain, rainwater falls on the top of the manhole cover plate and the top cover plate and flows outwards. When a small amount of rainwater enters the interior through the gap between the top cover plate and the cable, the recess of the manhole cover plate and the rubber gasket provide buffer space for the rainwater, preventing accumulation on the top of the rubber gasket and thus avoiding water seepage.

Description

Technical Field

[0001] This utility model relates to the field of groundwater monitoring technology, specifically to an integrated stratified monitoring module for soil and groundwater. Background Technology

[0002] Integrated soil and groundwater stratified monitoring targets the process of soil pollution migrating to groundwater. The working principle of the integrated soil and groundwater stratified monitoring device is mainly to acquire various parameters of soil and groundwater through sensors, and then transmit the data to the terminal for analysis and processing through the data acquisition and transmission system. The integrated soil and groundwater stratified monitoring device mainly consists of a sensor system, a data acquisition and transmission system, a power supply system, and well pipes and auxiliary facilities.

[0003] During monitoring, rainwater can easily seep into the well casing from the top, causing internal water leakage that affects both circuit safety and monitoring performance.

[0004] Utility model content.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated soil and groundwater stratified monitoring module, comprising:

[0006] A wellbore assembly, wherein a well cover assembly is mounted on top of the wellbore assembly, and a data transmitter is mounted on top of the well cover assembly;

[0007] The detection component and the slag-blocking component are installed inside the wellbore assembly. The detection component is installed inside the wellbore assembly and the slag-blocking component assists the detection component in performing detection. The detection component is electrically connected to the data transmitter via a cable.

[0008] The manhole cover assembly includes a manhole cover plate, which is fixedly installed on the top of the manhole cylinder assembly. The manhole cover plate has a conical protrusion at its center, and a top cover plate is formed at the center of the top of the manhole cover plate. A cable hole is formed at the center of the top of the top of the top cover plate. A circular groove is fixedly installed at the center of the top of the manhole cover plate, and a rubber gasket is fixedly installed in the circular groove. A groove is formed on the top of the manhole cover plate. The groove on the top of the manhole cover plate engages with the rubber gasket, and the inner wall of the rubber gasket tightly contacts the insulation layer of the cable, protecting the cable and improving the sealing effect. When it rains, rainwater falls on the top of the manhole cover plate and the top cover plate and flows outwards. When a small amount of rainwater enters the interior through the gap between the top cover plate and the cable, the groove of the manhole cover plate, in conjunction with the rubber gasket, provides buffer space for the rainwater, preventing accumulation on the top of the rubber gasket and thus preventing water seepage. The groove of the manhole cover plate is located directly below the top cover plate.

[0009] Preferably, the well assembly includes an upper well, a middle well, and a lower well. The upper well is located in the root zone of the soil, the middle well is located between the root zone and the aquifer, and the lower well is located within the aquifer. The upper, middle, and lower wells are arranged sequentially from top to bottom. Water inlet grooves are provided on the outer sides of both the lower and middle wells. A water-separating plate is fixedly installed at the bottom of the lower well. Through the cooperation of the water-separating plate and the separating ring, the water-separating plate prevents groundwater from entering the interior of the inner sealing cylinder. Simultaneously, the water-separating ring separates the groundwater at the gaps, preventing groundwater from mixing between different water layers and thus avoiding errors in water quality testing results. An inner sealing cylinder is fixedly installed on the inner walls of the middle and lower wells. The bottom of the inner sealing cylinder is tightly fitted to the top of the water-separating plate, and a separating ring is fixedly installed on the inner wall of the inner sealing cylinder, located between the lower and middle wells.

[0010] Preferably, the detection assembly includes a moisture sensor, a liquid level sensor, and a water conductivity sensor. The moisture sensor is installed inside the upper well casing, and its detection end penetrates the upper well casing and is inserted into the soil outside the upper well casing. The liquid level sensor is installed at the top of the inner sealing casing, and the water conductivity sensor is installed at the bottom of the inner wall of the inner sealing casing. The detection ends of both the liquid level sensor and the water conductivity sensor penetrate the inner sealing casing and are located in the gap between the inner sealing casing and the lower and middle well casings. The moisture sensor is model SM2801B, the liquid level sensor is model FST700-CS03, and the water conductivity sensor is model Rosemount150.

[0011] Preferably, the slag-blocking assembly includes an inner baffle, which is fixedly installed at the bottom of the outer side of the inner sealing cylinder. The detection end of the water conductivity sensor is located inside the inner baffle. The outer side of the inner baffle is uniformly provided with through grooves, and an outer arc cover is fixedly installed on the outer side of the inner baffle near the inner sealing cylinder. A conical hole plate is fixedly installed between the outer arc cover and the inner baffle, and through holes are uniformly provided on the outer side of the conical hole plate.

[0012] This invention provides an integrated stratified monitoring module for soil and groundwater. It has the following beneficial effects:

[0013] (I) This integrated soil and groundwater stratified monitoring module utilizes the groove on the top of the manhole cover plate and the rubber gasket ring. The tight fit between the inner wall of the rubber gasket ring and the cable insulation layer protects the cable while improving the sealing effect. During rain, rainwater falls on the top of the manhole cover plate and the top cover plate and flows outwards. When a small amount of rainwater enters the interior through the gap between the top cover plate and the cable, the groove on the manhole cover plate provides a buffer space for the rainwater, preventing it from accumulating on the top of the rubber gasket ring and causing seepage.

[0014] (ii) This integrated soil and groundwater stratified monitoring module uses a water-proof plate and a separating ring. The water-proof plate prevents groundwater from entering the inner casing, while the water-proof ring separates the groundwater in the gaps, preventing groundwater from mixing between different water layers. This can lead to errors in water quality testing results. Attached Figure Description
