DETAILED DESCRIPTION

[0029] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0030] like Figure 1 As shown, a soil evaporation and permeability monitoring device comprises an enclosed soil column 1. The shape of the enclosed soil column 1 can be square, circular or an irregular shape adapted to the region.

[0031] A soil monitoring cavity 12 for arranging soil is formed in the enclosed soil column 1, so that after the soil is filled into the soil monitoring cavity 12, real-time monitoring is performed with a monitoring device to obtain soil evaporation and infiltration data.

[0032] like Figure 1 , Figure 2 As shown, a weighing device 3 is provided at the bottom of the enclosed soil column 1 to monitor the weight of the soil in the soil monitoring cavity 12 in real time through the weighing device 3, so as to analyze the evaporation and permeability state of the soil. At the same time, a convex column step 11 is provided at the bottom of the enclosed soil column 1. The convex column step 11 is formed by connecting multiple layers of steps 111 with increasing length and width from top to bottom, and each step 111 is provided with a data acquisition sensor 113 and a soil solution sampler 114. Therefore, at the bottom of the enclosed soil column 1, a convex column terrace 11 formed by connecting multiple layers of steps 111 with increasing lengths and widths from top to bottom is provided to achieve the effect of forming multiple soil structure compositions of different depths in a single soil evaporation and permeability monitoring device. While ensuring the depth correlation between the soil structure compositions of different depths, the problem of data mutual influence caused by the same enclosed soil column 1 belonging to the soil evaporation and permeability monitoring device is avoided. Then, in combination with the data acquisition sensor 113 and the soil solution sampler 114 provided on each step 111, accurate monitoring of soil structures at different depths is achieved, so that the soil evaporation and permeability monitoring device has the effect of accurately monitoring water infiltration at different depths of the soil.

[0033] Among them, a triangular convex column 112 is arranged on the upper side of the step 111 located at the uppermost end. The triangular convex column 112 plays the role of guiding the penetration of water in the soil, and enables the multiple steps 111 to avoid water concentration when combined into a convex column platform 11, thereby significantly improving the use effect of the soil evaporation and penetration monitoring device.

[0034] like Figure 3 , Figure 4 As shown, a data processor 4 and a support base 2 for supporting the data processor 4 are provided at the lower end of the convex column step 11. The weighing measuring device 3 is fixed on the support base 2, and the data processor 4 is connected to the data acquisition sensor 113 and the soil solution sampler 114 on each step 111, so that when the data processor 4 is placed at the lower end of the convex column step 11, the space utilization rate is improved while the floor area is significantly reduced, and the corresponding monitoring data is effectively received in real time, thereby achieving the purpose of improving the accuracy of data processing; the support base 2 serves to stabilize and fix the weighing measuring device 3, so that the weighing measuring device 3 can achieve the effect of accurate measurement. The soil solution sampler 114 is connected to a negative pressure pump buffer bottle 41, and the negative pressure pump buffer bottle 41 is electrically connected to the data processor 4. Therefore, the negative pressure pump buffer bottle 41 realizes the control of the soil solution sampler 114 under the pressure adjustment of the negative pressure pump, thereby achieving the purpose of real-time monitoring and efficient measurement.

[0035] Among them, the step 111 is circular, polygonal or irregularly shaped to match the region, so that the steps 111 of different shapes play the role of increasing the style combination of the soil evaporation and infiltration monitoring device. At the same time, each step 111 is distributed with at least two data acquisition sensors 113 and soil solution samplers 114, so that when the data of different data acquisition sensors 113 and soil solution samplers 114 on the corresponding step 111 are integrated, the evaporation and infiltration data of the soil on the corresponding step 111 can be efficiently processed and the accuracy can be improved. Specifically, the data can be deleted by averaging, excluding abnormal values, etc., so that the soil evaporation and infiltration monitoring device can accurately monitor the infiltration water at different depths of the soil.

[0036] It should be noted that the step 111 includes a horizontal surface 1111 and a vertical surface 1112 .

[0037] Among them, the data acquisition sensor 113 is plugged and fixed on the corresponding vertical surface 1112, and the soil solution sampler 114 is plugged and fixed on the vertical surface 1112 connected to the corresponding horizontal surface 1111, thereby avoiding the problem of data error caused by setting the data acquisition sensor 113 and the soil solution sampler 114 on the horizontal surface 1111, and the installation and fixation of the data acquisition sensor 113 and the soil solution sampler 114 are realized through the corresponding vertical surface 1112, so that the soil evaporation and infiltration monitoring device has the effect of accurately monitoring the infiltration water of different depths of the soil while having a simple structure and convenient use.

[0038] It should be mentioned that the soil solution sampler 114 is U-shaped, and the lower end is inserted into the corresponding vertical surface 1112, and the upper end opening is arranged opposite to the corresponding data acquisition sensor 113. Therefore, the U-shaped soil solution sampler 114 and the relatively arranged data acquisition sensor 113 accurately monitor the soil within the set area, so as to achieve the purpose of accurately monitoring the infiltration water of different depths in the soil when cooperating with the data processor 4. The lower end of the soil solution sampler 114 is connected to a rotator for circumferential rotation. When the rotator is in operation, it drives the soil solution sampler 114 to rotate, so as to achieve the effect of adjusting the height of the upper end opening of the soil solution sampler 114 when rotating with the axis of the lower end opening as the axis, so as to further monitor the infiltration water of the soil at different heights on the corresponding depth step 111.

[0039] Correspondingly, the data acquisition sensor 113 includes a sensing probe 1131 that is horizontally arranged and penetrates from the corresponding vertical surface 1112, and a bent connection portion 1132 that is plugged and fixed in the corresponding vertical surface 1112. The bent connection portion 1132 is electrically connected to the data processor 4. By making the sensing probe 1131 horizontally arranged and monitoring the data of the soil at the corresponding depth in real time, and the bent connection portion 1132 plays a role in significantly improving the fixing stability of the data acquisition sensor 113, the soil evaporation and infiltration monitoring device will have the effect of accurately monitoring the infiltration water at different depths of the soil.

[0040] In summary, the present application arranges a convex column terrace 11 at the bottom of the enclosed soil column 1, which is formed by connecting multiple layers of steps 111 with increasing lengths and widths from top to bottom, and then installs a fixed data acquisition sensor 113 and a soil solution sampler 114 on the vertical surface 1112 of the step 111 to realize real-time monitoring of the data of the regional soil on the corresponding step 111, and combines the negative pressure pump buffer bottle 41 to realize the adjustment and control of the soil solution sampler 114, so that the soil evaporation and infiltration monitoring device has the effect of accurately monitoring the infiltration water at different depths of the soil.
