DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-5, the present utility model provides a protection device for a soil moisture detection sensor, including a fixing plate 1. At the middle position of the lower surface of the fixing plate 1, there is a protection tube 2. At the lower end of the protection tube 2, there is an insertion soil chute 3. At the upper end of the fixing plate 1, there is a connecting plate 4. At the middle position of the upper surface of the connecting plate 4, corresponding to the position of the protection tube 2, there is a device tube 5. Inside the device tube 5, there is a limiting plate 6. At the middle position of the limiting plate 6, there is a detection probe 7 passing through. The lower end of the detection probe 7 extends into the interior of the protection tube 2. At the position corresponding to the detection probe 7 on the side wall of the protection tube 2, there is a through hole 8. At the middle position of the fixing plate 1 and above the protection tube 4, there is a splicing tube 9. The splicing tube 9 passes through the connecting plate 4 and is spliced and connected with the device tube 5.

[0018] During use, first, the protection tube 2 is set at the soil position to be detected. The protection tube 2 is smoothly inserted into the interior of the soil through the insertion soil chute 3 provided at the lower end, ensuring that the lower surface of the fixing plate 1 abuts against the soil. The device tube 5 and the protection tube 2 are spliced and connected through the splicing tube 9. The device tube 5 abuts against the splicing tube 9 through the limiting plate 6, so as to support the overall device through the fixing plate 1. The device tube 5 is a screenshot of the lower part of an existing soil moisture detection device, ensuring that the lower end of the connecting plate 4 abuts against the fixing plate 1. At this time, the detection probe 7 is inserted into the interior of the soil inside the protection tube 2. A through hole 8 is opened on the side wall of the protection tube 2 to ensure that the soil moisture near it is the same as that inside the protection tube 2, thereby ensuring the accuracy of soil moisture detection.

[0019] Both the fixing plate 1 and the connecting plate 4 are square plate structures. The outer edge of the fixing plate 1 extends outside the connecting plate 4. At the positions corresponding to the four corners of the connecting plate 4 on the upper surface of the fixing plate 1, there are fixing bolts 10. At the positions corresponding to the fixing bolts 10 on the connecting plate 4, there are bolt holes 11. By setting the fixing bolts 10 on the fixing plate 1 and opening the bolt holes 11 on the connecting plate 4, the fixing bolts 10 are inserted into the interior of the bolt holes 11, and the connecting plate 4 is fixedly set on the fixing plate 1 through the threaded connection of nuts with the fixing bolts 10.

[0020] Between the lower surface of the fixing plate 1 and the outer surface of the protection tube 2, there is a lower reinforcing plate 12 to enhance the connection strength between the fixing plate 1 and the protection tube 2. Between the upper surface of the connecting plate 4 and the outer surface of the device tube 5, there is an upper reinforcing plate 13 to enhance the connection strength between the connecting plate 4 and the device tube 5.

[0021] The lower end of the splicing tube 9 is fixedly connected with the protection tube 4, and the upper end of the splicing tube 9 is spliced and connected with the device tube 5. When it is necessary to disassemble the detection device, the fixing bolts 10 can be loosened, so that the device tube 5 is separated from the splicing tube 9.

[0022] The upper end of the splicing pipe 9 abuts against the lower surface of the limiting plate 6. By the limiting plate 6 abutting against the splicing pipe 9, part of the weight of the device is supported.
