Description

Technical Field

[0001] This utility model relates to the field of leachate collection and monitoring technology, and in particular to a device for collecting and monitoring farmland groundwater leachate. Background Technology

[0002] The equipment for collecting and monitoring farmland groundwater leachate is a key device for real-time acquisition and analysis of leachate in the soil. It can be applied to fields such as agricultural environmental monitoring, pollution control, and groundwater protection.

[0003] In the existing technology, the collection and monitoring device for farmland groundwater leachate has a fixed collection range, which is not convenient to adjust according to needs. Therefore, we propose a farmland groundwater leachate collection and monitoring device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of conventional agricultural groundwater leachate collection and monitoring devices, which have a fixed collection range and are not easily adjustable according to needs. Therefore, this invention proposes an agricultural groundwater leachate collection and monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for collecting and monitoring farmland groundwater leachate includes:

[0007] The collection box and the box cover installed on top of the collection box, the box cover having multiple first infiltration holes;

[0008] The sensor array is located inside the collection box;

[0009] Two rectangular mounting ports are provided on the collection box. A first connecting plate is inserted into each of the two rectangular mounting ports. A rectangular horizontal hole is opened on each of the two first connecting plates.

[0010] Two second connecting plates are slidably installed in two rectangular horizontal holes, and one side of each of the two second connecting plates is provided in a water guide groove;

[0011] Multiple second permeation holes are located on the top of the first connecting plate;

[0012] Multiple third permeation holes are located on the top of the second connecting plate, and all of the multiple third permeation holes are connected to the water guide channel;

[0013] Two first locking bolts are threaded onto two first connecting plates respectively, and are used to fix the two second connecting plates.

[0014] Preferably, the bottom inner walls of both water guide channels are inclined.

[0015] Preferably, the sensor group includes a moisture sensor, a temperature sensor, a conductivity sensor, and a nitrogen, phosphorus, and potassium sensor.

[0016] Preferably, two mounting plates are fixedly installed on the outside of the collection box. Each mounting plate has a rectangular groove with two openings, and a baffle is slidably installed inside each rectangular groove.

[0017] Preferably, a limiting groove is provided at the bottom of both baffles, and a limiting block is fixedly installed on the top of both first connecting plates, with the limiting block engaging with the limiting groove.

[0018] Preferably, a push-pull block is fixedly installed on one side of each of the two baffles, and a second locking bolt is threaded onto each of the two mounting plates. The second locking bolt is used to lock and fix the baffles.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] This solution involves inserting two first connecting plates into two rectangular mounting openings, pushing the baffle downwards, and engaging the limiting groove and limiting block at the bottom of the baffle to restrict the first connecting plates. The baffle is then fixed with a second locking bolt. Next, the two second connecting plates are pulled laterally to connect the second permeation hole with the corresponding third permeation hole, thus adjusting the collection range. Moving the two second connecting plates further apart increases the collection range, while moving them closer together decreases it. The entire device is buried underground in farmland. Leachate enters the collection tank through the first permeation hole, and simultaneously enters the water guide channel through the second and third permeation holes, then flows into the collection tank. The leachate is monitored by a sensor array within the collection tank.

[0021] This invention allows for adjustment of the collection range to meet different usage needs. Attached Figure Description

[0030] Sensor group 4 is located inside collection box 1;

[0031] Two rectangular mounting ports 5 are provided on the collection box 1. A first connecting plate 6 is inserted into each of the two rectangular mounting ports 5. A rectangular horizontal hole 7 is opened on each of the two first connecting plates 6.

[0032] Two second connecting plates 8 are slidably installed in two rectangular horizontal holes 7 respectively, and one side of each of the two second connecting plates 8 is provided in the water guide groove 9;

[0033] Multiple second permeation holes 10 are provided on the top of the first connecting plate 6;

[0034] Multiple third permeation holes 11 are provided on the top of the second connecting plate 8, and all of the multiple third permeation holes 11 are connected to the water guide channel 9;

[0035] Two first locking bolts 12 are threaded onto two first connecting plates 6 respectively, and are used to fix two second connecting plates 8.

[0036] In this embodiment, the bottom inner walls of both water guide channels 9 are inclined.

[0037] In this embodiment, the sensor group 4 includes a moisture sensor, a temperature sensor, a conductivity sensor, and a nitrogen, phosphorus, and potassium sensor. A transmitter is installed on the collection box 1, and the sensor group is connected to the transmitter. The data collected by the sensor group is sent to a remote terminal through the transmitter. This principle is quite mature in the existing technology and will not be described in detail here.

[0038] In this embodiment, two mounting plates 14 are fixedly installed on the outside of the collection box 1. Each mounting plate 14 has a rectangular groove with two openings, and a baffle 15 is slidably installed in each of the two rectangular grooves.

[0039] In this embodiment, the bottom of both baffles 15 is provided with a limiting groove 17, and the top of both first connecting plates 6 is fixedly installed with a limiting block 13, which is engaged with the limiting groove 17.

[0040] In this embodiment, a push-pull block is fixedly installed on one side of each of the two baffles 15, and a second locking bolt 16 is threadedly installed on each of the two mounting plates 14. The second locking bolt 16 is used to lock and fix the baffles 15.

[0041] In this embodiment, during use, the two first connecting plates 6 are inserted into the two rectangular mounting holes 5, and the baffle 15 is pushed downward. The limiting groove 17 at the bottom of the baffle 15 is engaged with the limiting block 13 to restrict the first connecting plates 6. The baffle 15 is fixed by the second locking bolt 16. Then, the two second connecting plates 8 are pulled to move laterally, so that the second permeation hole 10 is connected to the corresponding third permeation hole 11. The collection range is adjusted. If the two second connecting plates 8 are far apart, the collection range increases. If the two second connecting plates 8 are close together, the collection range decreases. The entire device is buried underground in the farmland. The leachate enters the collection box 1 from the first permeation hole 3. At the same time, the leachate enters the water guide channel 9 from the second permeation hole 10 and the third permeation hole 11, and then enters the collection box 1 from the water guide channel 9. The leachate is monitored by the sensor group 4 in the collection box 1.
