[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] like Figure 1-5 As shown, a sensor protection device for a granary includes a bottom plate 1, a tube 2, a wind cover tube 3 and a sensor 4. The tube 2 is vertically installed at the center of the upper surface of the bottom plate 1. The tube 2 is perpendicular to the bottom plate 1. A connector 21 is provided at one end of the tube 2 away from the bottom plate 1.

[0028] The outer surface of the connector 21 is provided with an external thread 22, and the inner surface of the air cover tube 3 is provided with an internal thread 32 below. The air cover tube 3 is threadedly connected to the upper end of the connector 21 by the mutual engagement of the external thread 22 and the internal thread 32. When the sensor 4 needs to be repaired or replaced, it is only necessary to unscrew the air cover tube 3.

[0029] The surface of the air cover tube 3 is provided with a plurality of air holes 31 connected to the inside of the air cover tube 3, and the air in the granary can flow into the air cover tube 3 through the air holes 31. The barrel 2 and the connector 21 are provided with cavities connected to each other. The lower surface of the sensor 4 is provided with a sensor signal line 41, and the sensor 4 is installed on the upper surface of the connector 21. The sensor signal line 41 is located in the cavity, and the barrel 2 protects the sensor signal line 41.

[0030] It also includes a scraper ring 5, which is movably mounted on the wind cover tube 3. The inner wall of the scraper ring 5 is provided with a plurality of magnets 51, and the inner wall of the scraper ring 5 is also provided with a plurality of scraping bristles 52. The scraper ring 5 is movably mounted on the wind cover tube 3 through the magnets 51. When dust accumulates in the wind hole 31, the scraper ring 5 can be pulled up and down, and the scraping bristles 52 in the scraper ring 5 can sweep away the dust accumulated in the wind hole 31.

[0031] The air holes 31 are arranged in several layers, and the distances between the air holes 31 in adjacent layers are consistent.

[0032] Each layer has a plurality of air holes 31 , and each layer of air holes 31 is evenly and equidistantly distributed on the surface of the air cover tube 3 , that is, the layout of the air holes 31 is relatively uniform.

[0033] The bottom plate 1 is in the shape of a rounded square, which is safer and prevents sharp corners from hitting people's feet. Through holes 11 are set at the four corners of the upper surface of the bottom plate 1, and the whole device can be installed on the ground of the granary by passing bolts through the through holes 11.

[0034] The vertical axis of the bobbin 2 is aligned with the vertical axis of the wind cover tube 3, and the cross-sectional dimensions of the bobbin 2 are consistent with the cross-sectional dimensions of the wind cover tube 3. When the wind cover tube 3 is installed on the bobbin 2, the overall aesthetics is also better.

[0035] The four through holes 11 are symmetrically distributed with the center position of the upper surface of the bottom plate 1 as the center, and are installed using bolts, so the stability of the entire device is good.

[0036] The inner top surface of the wind cover tube 3 is 4-6 cm away from the upper surface of the sensor 4 , so the air flow in the granary can smoothly pass through the wind cover tube 3 , and the gas in the air flow can be easily detected by the sensor 4 .

[0037] In summary: unscrew the wind cover tube 3, put the sensor signal line 41 into the barrel 2, install the sensor 4 on the upper surface of the connector 21, and let the sensor signal line 41 naturally fall into the cavity of the barrel 2, and then tighten the wind cover tube 3;

[0038] Four bolts are used to pass through the through holes 11 to fix the entire device on the bottom surface of the granary. The air in the granary can freely pass through the wind holes 31 and enter the interior of the wind cover tube 3, that is, the sensor 4 can contact the air in the granary. The sensor 4 can normally detect the humidity, oxygen content, phosphine content, etc. in the air in the granary. At the same time, the wind cover tube 3 plays a detection and protection role for the sensor 4, and the service life is longer; after the wind cover tube 3 is installed, the overall structure of the wind cover tube 3 and the barrel 2 is also more beautiful; with long-term use, when dust accumulates in the wind hole 31, the scraper ring 5 can be pulled up and down, and the scraper 52 in the scraper ring 5 can sweep away the dust accumulated in the wind hole 31, which can ensure that the air in the granary passes through the wind hole 31 smoothly, so that the detection of the sensor 4 is accurate.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
