Description

TECHNICAL FIELD

[0001] The present application relates to the field of detection devices, in particular to an environmental detection device and a detection method. BACKGROUND

[0002] The environmental monitoring device is a detection device with multiple detection functions for detecting air quality or soil quality in an environment. However, the existing environmental detection device is large in size and can only be placed indoors. When detecting trace elements in soil, multiple soil samples need to be taken and transported to the laboratory for detection one by one. Since environmental detection work has certain environmental specificity, it is impossible to complete the detection of soil quality and the quality of the contained liquid at the same time by the same device. SUMMARY

[0003] The present application provides an environmental detection device and a detection method, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by the present application to solve its technical problems is: An environmental detection device, comprising a shell, a pedal, a partition plate, a soil trace element detector and a liquid trace element detector arranged in the shell, the pedal is symmetrically arranged on the left and right sides of the shell, the lower end of the shell is provided with a detection cavity, the partition plate is arranged in the detection cavity, the detection end of the soil trace element detector extends downward and penetrates through the partition plate, and the detection end of the liquid trace element detector extends into the partition plate. The outer side of the upper end of the shell is further provided with an air compressor, a negative pressure cavity is formed between the inner end of the partition plate and the detection cavity, and the air compressor is connected in communication with the negative pressure cavity to extract air in the negative pressure cavity by the air compressor to create negative pressure. The lower part of the partition plate is provided with a liquid inlet on each side, a permeable membrane is arranged in each liquid inlet, liquid can penetrate into the negative pressure cavity through the permeable membrane, and the lower part of the partition plate is provided with a dish-shaped structure, the two liquid inlets are arranged close to the left and right side edges of the dish-shaped structure, when liquid penetrates into the negative pressure cavity through the permeable membrane, it will flow to the surface of the dish-shaped structure, and the detection end of the liquid trace element detector extends into the dish-shaped structure.

[0005] A preferred technical solution, the upper end of the partition plate is provided with an L-shaped structure, the L-shaped structure extends to the side and the upper end respectively, and abuts with the surface of the liquid trace element detector and the inner end of the shell respectively, and the output shaft of the soil trace element detector penetrates through the L-shaped structure.

[0006] In a preferred embodiment, a swing plate is provided on each of the two sides of the lower end of the housing. The two swing plates are driven to swing by an electric push rod. The swing plates are movably connected to the housing through a sliding shaft. A sliding groove is provided on the surface of the housing at the corresponding position of the sliding shaft. The sliding groove extends along the longitudinal direction of the housing, and the sliding shaft is slidably disposed in the sliding groove. The electric push rod is rotatably connected to the side of the housing and the end of the swing plate at both ends, respectively. The swing plate and the sliding shaft are adjusted by the electric push rod to swing. When the swing plates on both sides swing towards the partition plate at the same time until they are parallel, the detection cavity on the lower side of the housing is closed.

[0007] In a preferred embodiment, a heat-conducting copper plate is provided on the inner side of the housing near the two seepage ports, and an electric heating plate is provided inside the heat-conducting copper plate. The electric heating plate is heated by electricity. The heat-conducting copper plate has a bent structure and extends toward the detection end of the soil trace element detector.

[0008] In a preferred embodiment, the pedal surface is further provided with anti-slip texture and a level. The level is located in the middle of the pedal, while the anti-slip texture is located on the side of the pedal away from the housing. The side of the pedal near the electric push rod has an opening corresponding to the electric push rod.

[0009] An environmental monitoring method, based on the aforementioned environmental monitoring device, includes the following steps: S1: Place the environmental monitoring device above the soil to be tested and press it into the soil so that the soil enters the detection chamber on the lower side of the housing; S2: Drive the corresponding swing plate to swing through the electric push rods 11 on both sides, and close the detection cavity on the lower side of the shell, so that the soil in the detection cavity is lifted upward with the swing of the swing plate, repeating multiple times until the soil submerges the heat-conducting copper plate in the detection cavity. S3: The electric heating plate is powered on and heated to increase the temperature of the surrounding soil, causing the soil moisture to evaporate and increasing the soil dryness. The soil trace element detector detects the trace elements contained in the soil through its detection end. At the same time, the air compressor creates negative pressure to allow the soil moisture to permeate through the permeation membrane into the dish-shaped structure inside the partition plate. The liquid trace element detector detects the trace elements contained in the liquid through its detection end. When the swing plate is closed, the output shaft of the electric push rod must be retracted and the environmental detection device must be pressed down simultaneously, and the speed at which the environmental detection device is pressed down is the same as the retraction speed of the output shaft of the electric push rod.

[0010] Compared with existing technologies, this technical solution has the following advantages: In this invention, the environmental detection device can be pressed down, and the sliding plate can be opened by an electric push rod, allowing the sliding plate to embed into the soil. The sliding plate can then be closed again by the electric push rod. While closing the sliding plate, the environmental detection device can be pressed down further, allowing the soil to enter the housing. The soil can be heated by a heat-conducting copper plate, causing the moisture in the soil to evaporate. At the same time, a negative pressure is created by an air compressor, allowing the moisture in the soil to pass through a permeable membrane into a dish-shaped structure inside the partition plate. At this point, the soil trace element detector and the liquid trace element detector can simultaneously detect the elements contained in the soil and liquid, effectively solving the technical problems of existing environmental detection equipment.

Detailed Implementation

[0019] like Figures 1 to 6 As shown, the present invention proposes an environmental monitoring device, including a housing 1, a pedal 2, a partition plate 3, and a soil trace element detector 4 and a liquid trace element detector 5 disposed within the housing 1. The pedal 2 is symmetrically arranged on the left and right sides of the housing 1. The lower end of the housing 1 is provided with a detection cavity, and the partition plate 3 is disposed within the detection cavity. The detection end of the soil trace element detector 4 extends downward and passes through the partition plate 3, and the detection end of the liquid trace element detector 5 extends into the partition plate 3. An air compressor 12 is also provided on the outer side of the upper end of the housing 1. A negative pressure chamber is formed between the inner end of the partition plate 3 and the detection chamber. The air compressor 12 is connected to the negative pressure chamber through a connecting pipe so as to draw air from the negative pressure chamber and create negative pressure. The partition plate 3 has a seepage port 31 on each of its lower sides. Both seepage ports 31 are equipped with a permeation membrane 311. Liquid can permeate through the permeation membrane 311 into the negative pressure chamber. The partition plate 3 has a dish-shaped structure at its lower part. The two seepage ports 31 are respectively located near the left and right edges of the dish-shaped structure. When liquid permeates through the permeation membrane 311 into the negative pressure chamber, it will flow to the surface of the dish-shaped structure. The detection end of the liquid trace element detector 5 extends into the dish-shaped structure.

[0020] The permeable membrane 311 is selectively permeable, allowing only liquids in the soil to permeate through the infiltration port 31, while blocking dry substances such as soil particles and solid impurities. This design prevents impurities from entering the negative pressure chamber, ensuring that the subsequent liquid trace element detector 5 contacts a pure liquid sample, eliminating the interference of impurities on detection accuracy, which is a fundamental prerequisite for subsequent targeted detection.

[0021] Air compressor 12 draws air from the negative pressure chamber through the connecting pipe, causing the negative pressure chamber formed by the partition plate 3 and the detection chamber to generate suction: on the one hand, it accelerates the entry of liquid in the soil through the permeation membrane 311 into the negative pressure chamber, shortening the sample acquisition time; on the other hand, because the seepage port 31 is close to the dish-shaped structure at the bottom of the partition plate 3, the permeated liquid can naturally flow to the dish-shaped structure and concentrate, which just comes into contact with the detection end of the liquid trace element detector 5 that extends into the dish-shaped structure, without the need for additional manual sample transfer.

[0022] The soil trace element detector can directly test the soil in the detection chamber (i.e., one sample, double detection), which can effectively reduce the time required for testing a certain area without the cumbersome detection process of the prior art.

[0023] Furthermore, to prevent dust or soil from entering the soil trace element detector through the gaps, the detection chamber in this invention is separated by a partition plate 3. The upper end of the partition plate 3 is provided with an L-shaped structure, which extends to the side and the upper end, and is respectively connected to the surface of the liquid trace element detector 5 and the inner end of the housing 1. The output shaft of the soil trace element detector 4 passes through the L-shaped structure.

[0024] Furthermore, a swing plate 14 is provided on each side of the lower end of the housing 1. The two swing plates 14 are driven to swing by an electric push rod 11. The swing plates 14 are movably connected to the housing 1 through a sliding shaft 141. A sliding groove 13 is provided on the surface of the housing 1 at the corresponding position of the sliding shaft 141. The sliding groove 13 extends along the longitudinal direction of the housing 1, and the sliding shaft 141 slides in the sliding groove 13. The electric push rod 11 is rotatably connected at both ends to the side of the housing 1 and the end of the swing plate 14, respectively. The swing plate 14 and the sliding shaft 141 are adjusted by the electric push rod 11 to swing with the electric push rod 11 as the fulcrum. When the swing plates 14 on both sides swing towards the partition plate 3 and become parallel, the detection cavity on the lower side of the housing 1 is closed. When the swing plate 14 is closed, the output shaft of the electric push rod 11 needs to be retracted at the same time and the environmental detection device needs to be pressed down. The speed at which the environmental detection device is pressed down is the same as the retraction speed of the output shaft of the electric push rod 11.

[0025] The following will explain the specific process of the swing plate 14 pushing the soil upward: Initially, the swing plate 14 is in an outward-opening state (forming a certain angle with the lower end of the housing 1), and the lower opening of the detection chamber at the lower end of the housing 1 is fully exposed, which facilitates the soil to enter the area below the detection chamber. The electric push rods 11 on both sides extend to drive the swing plates 14 on both sides to close, and collect the soil between the two swing plates 14. Subsequently, the output shaft of the electric push rod 11 begins to retract, and at the same time, the equipment presses down longitudinally (at the same speed as the push rod retraction speed). At this time, the housing 1 drives the slide groove 13 to move downward synchronously, and the retraction force of the electric push rod 11 pulls the end of the swing plate 14 to swing inward toward the inside of the housing 1 (towards the partition plate 3). The sliding shaft 141 slides downward longitudinally in the slide groove 13 with the movement of the swing plate 14 (because the equipment presses down, the downward movement speed of the slide groove matches the downward movement speed of the sliding shaft to avoid jamming). Since the movement trajectory of the swing plate 14 is "circular arc swing with the sliding shaft 141 as the fulcrum", and the sliding shaft 141 moves down synchronously in the slide groove 13 (in coordination with the equipment pressing down), the contact point between the swing plate 14 and the soil will generate an upward squeezing force. The swing plates 14 on both sides will move inward synchronously to prevent the soil from leaking out from the side. The upward pushing force in the longitudinal direction will directly act on the soil below the detection chamber, squeezing the loose soil upward. When the output shaft of the electric push rod 11 retracts to its limit position, the two swing plates 14 swing to a state parallel to the partition plate 3, completely closing the detection cavity on the lower side of the housing 1; During this process, the swing plate 14 continuously pushes the soil upward until the soil is squeezed into the detection chamber and makes full contact with the detection end of the soil trace element detector 4 that penetrates the partition plate 3. At the same time, the liquid trace element detector 5 is not affected by impurities from the pushed soil due to the sealing protection of the L-shaped structure.

[0026] Furthermore, the inner surface of the housing 1 near the two seepage ports 31 is provided with heat-conducting copper plates 15, and an electric heating plate 151 is provided inside the heat-conducting copper plate 15. The electric heating plate 151 is heated by electricity. The heat-conducting copper plate 15 has a bent structure and extends towards the detection end of the soil trace element detector 4. The surface of the pedal 2 is also provided with anti-slip texture 21 and a level 22. The level 22 is located in the middle of the pedal 2, while the anti-slip texture 21 is located on the side of the pedal 2 away from the housing 1. The side of the pedal 2 near the electric push rod 11 has an opening corresponding to the electric push rod 11.

[0027] When the electric heating plate 151 is powered on, heat is directionally transferred to the soil area inside the detection chamber through the bent heat-conducting copper plate 15. Heating can quickly evaporate excess water in the soil. If the soil moisture content is too high, it will cover the detection end of the soil trace element detector 4, hindering the direct contact between the detector and soil particles. After heating, the moisture is reduced, the soil particles become looser, and the detection end can quickly embed itself in the soil and fully contact the solid soil, shortening the response time of the detection signal, while avoiding the interference of moisture on the detection circuit or sensor.

[0028] It should be explained that the partition plate 3 in this invention is fixed to the housing 1 by screws and is a detachable structure. After a single inspection operation is completed, the screws on the partition plate 3 can be unscrewed and the partition plate 3 can be removed to pour out the water inside for the next use.

[0029] Based on the above, this invention also proposes an environmental detection method. Based on the aforementioned environmental detection device, the detection method includes the following steps: S1: Place the environmental monitoring device above the soil to be tested and press it into the soil so that the soil enters the detection chamber on the lower side of the housing 1; S2: Drive the corresponding swing plate 14 to swing through the electric push rods 11 on both sides, and close the detection cavity on the lower side of the housing 1, so that the soil in the detection cavity is lifted upward with the swing of the swing plate 14, repeating multiple times until the soil submerges the heat-conducting copper plate 15 in the detection cavity. S3: The electric heating plate 151 is energized and heated to increase the temperature of the surrounding soil, causing the soil moisture to evaporate and increasing the soil dryness. The trace elements contained in the soil are detected by the detection end of the soil trace element detector 4. At the same time, the air compressor 12 creates negative pressure, causing the soil moisture to permeate through the permeation membrane 311 into the dish-shaped structure in the partition plate 3. The trace elements contained in the liquid are detected by the detection end of the liquid trace element detector 5. The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
