[0035] Example 1

[0036] See also Figure 1-7 A field test partition device comprises an isolation frame 100 and an impermeable membrane 2; the isolation frame 100 comprises four frame borders 1 and an arc-shaped card plate 13 formed by a plurality of first side panels 11 and a second side panel 12 detachably connected; every two adjacent frame borders 1 are detachably connected by the arc-shaped card plate 13 to form the isolation frame 100; the impermeable membrane 2 is covered on the isolation frame 100; a pressure rod 3 is clamped on each side of the isolation frame 100.

[0037] It can be understood that when conducting experiments in the field (paddy field), a partition device is required to separate a small area according to needs. Therefore, multiple first side panels 11 and second side panels 12 need to be detachably connected together to form a frame 1, and finally each side is connected together through an arc-shaped card plate 13 to form an isolation frame 100 with a square frame structure. In order to facilitate the movement of the first side panel 11 and the second side panel 12 into the paddy field, in this embodiment, the first side panel 11 and the second side panel 12 are made of wooden boards of equal size, and the length is 100 cm, the width is 100 m, and the thickness is 10 cm. This size is for example explanation, but not as a limitation of the present scheme. In other embodiments, the first side panel 11 and the second side panel 12 can be made of other specifications and materials. After the first side panel 11 and the second side panel 12 are connected to a side of a certain length required, the two adjacent sides are spliced ​​together through the arc-shaped card plate 13 to form a square After the isolation frame 100 is assembled, a layer of impermeable membrane 2 is laid on each side of the isolation wide body and the arc-shaped card plate 13. The impermeable membrane 2 is arranged close to the first side plate 11, the second side plate 12 and the arc-shaped card plate 13, and all cover and extend to the bottom of the above three. After covering the impermeable membrane 2, after the pressure rod 3 is clamped on each side of the isolation frame 100, the pressure rod 3 is pressed downward with force to fix the first side plate 11, the second side rod and the arc-shaped card plate The bottom of the plate 13 is pressed into the soil in the water, so that the entire isolation frame 100 sinks into the soil. In addition, some soil is stacked on the lower part of the isolation frame 100 where the soil leaks out through manual assistance, so that the sealing shape is better. The isolation frame 100 is stably inserted into the paddy field to form an isolation partition. At the same time, the pressure rod 3 presses the anti-seepage membrane 2 to prevent the anti-seepage membrane 2 from sliding off the edge of the isolation frame 100, causing some places to be uncovered and causing leakage.

[0038] Please combine Figure 2-4 , defining the direction perpendicular to the surface of the paddy field as the longitudinal direction, first card slots 111 are provided at both ends of the longitudinal direction of the first side panel 11, a second card slot 121 having the same structure as the first card slot 111 is provided at one end of the longitudinal direction of the second side panel 12, and a first card strip 122 is provided at the other end; the first card strip 122 corresponds to the first card slot 111 and the second card slot 121.

[0039] It can be understood that the first card slot 111 and the second card slot 121 are both T-shaped card slots of the structure, and the first card strip 122 is a T-shaped card strip corresponding to the above two structures. During the splicing process, when the two second side panels 12 are connected to each other, the first card strip 122 is inserted into the second card slot 121 of the other second side panel 12; since both ends of the second side panel 12 are card slots, the two first side panels 11 cannot be connected to each other, and the first side panel 11 can only be inserted into the second card slot 121 of the second side panel 12 through the first card. When the length of each side needs to be increased, the length of each side can be increased by adding multiple second side panels 12 to be connected to each other.

[0040] Please combine Figure 5 The arc-shaped card plate 13 has a second card strip 131 at both longitudinal ends. The second card strip 131 can be freely connected to the first card slot 111 or the second card slot 121 .

[0041] It can be understood that the second card strip 131 is a protruding T-shaped structure. During installation, since the length of the edge is formed by connecting the second side panels 12 to each other, one end of each edge is exposed by the first card strip 122 and the second card slot 121 is idle. At this time, a first card slot 111 of a first side panel 11 is inserted into the first card strip 122, that is, each frame 1 of the isolation frame 100 has a first side panel 11 as the head end and the second side panel 12 as the tail end. The head end and the tail end are idle with the first card slot 111 and the second card slot 121, so that the second card strips 131 of the T-shaped structure protruding at both ends of the arc-shaped card plate 13 are respectively inserted into the first card slot 111 and the second card slot 121, so that the two adjacent edges are connected together to form a square isolation frame 100.

[0042] Please combine Figure 1 , 3 4 , the first side plate 11 and the second side plate 12 are both provided with a snap-in ear 4 at the top, the snap-in ear 4 is provided with an elastic closing opening 41 , and the pressure rod 3 is snap-connected at the elastic closing opening 41 .

[0043] It can be understood that a snap-in ear 4 is fixed on both sides of the top of each first side panel 11 or the second side panel 12, and the snap-in ear 4 includes a first arc plate 43 and a second arc plate with elasticity, one end of the first arc plate 43 and the second arc plate is fixed to the top of the first side panel 11 or the second side panel 12, and the first arc plate 43 and the second arc plate at the other end form an elastic closing 41 for snapping the pressure rod 3, so that the pressure rod 3 can be clamped in the snap-in ear 4.

[0044] Please combine Figure 6 , 7The bottoms of both ends of the pressure rod 3 are provided with pressure blocks 31 corresponding to the second clamping strip 131. It can be understood that when the pressure rod 3 is pressed into the frame 1 of the isolation frame 100, the pressure blocks 31 can align with the first clamping strip 122 to press the arc clamping plate 13 into the soil, thereby improving the structural stability of the entire isolation frame 100.

[0045] Please combine Figure 3 , 4 The bottoms of the first side plate 11, the second side plate 12 and the arc-shaped clamping plate 13 are all provided with a pointed plate 5 with a triangular cross-section, and the triangular pointed plate 5 helps to insert the above three into the soil of the paddy field.

[0046] Please combine Figure 3 , 4 , the first side plate 11 and the second side plate 12 are provided with a plurality of grooves 7. The first function of the grooves 7 is to reduce resistance when the first side plate 11 and the second side plate 12 are inserted into the soil, and the second function is that after the isolation frame 100 is inserted into the soil, when some silt is laid on the anti-seepage membrane 2, the anti-seepage membrane 2 can be closely attached to the first side plate 11 or the second side plate 12 to prevent the anti-seepage membrane 2 from sliding left and right.

[0047] Please combine Figure 1 A plurality of exhaust holes 6 are provided on the top of the anti-seepage membrane 2. In the present embodiment, the exhaust holes 6 are provided at positions corresponding to the arc-shaped clamping plate 13, that is, at the four corners of the isolation frame 100. The exhaust holes 6 can discharge the gas between the anti-seepage membrane 2 and the isolation frame 100 in time when the isolation frame 100 is inserted into the soil or when the bottom of the anti-seepage membrane 2 is coated with silt.

[0048] It is also noted that the pressure rod 3 includes a plurality of support rods, and each first side panel 11 or second side panel 12 is clamped with one of the support rods. This design is mainly for facilitating the movement of a first side panel 11 or a second side panel 12 separately by clamping the support rods on the clamping ears 4, and for pressing the first side panel 11 and the second side panel 12 into the water separately.

[0049] In summary, compared with the prior art, this solution has the following advantages:

[0050] 1. The isolation frame 100 is formed by using a detachably connected first side plate 11, a second side plate 12 and an arc-shaped clamping plate 13, which is easy to install and disassemble, saving time and effort.

[0051] 2. A layer of impermeable membrane 2 is covered on the isolation frame 100 to improve its sealing performance, prevent water leakage inside the isolation frame 100, and improve the reliability of the test.

[0052] 3. After covering with a layer of impermeable membrane 2, water leakage in the fixed frame can be prevented. At the same time, a pressure rod 3 is clamped after covering with a layer of impermeable membrane 2 to prevent the impermeable membrane 2 from sliding off from one side of any side of the isolation frame 100, causing the impermeable membrane 2 to fall off and cause leakage.
