Description

Technical Field

[0001] This utility model relates to the field of grain storage detection technology, specifically to a sensing component for detecting the state of stored grain. Background Technology

[0002] Grain storage temperature measuring cables are devices specifically designed for temperature monitoring in grain warehouses. They can effectively monitor temperature changes during grain storage and ensure the safe storage of grain.

[0003] Existing grain storage temperature measuring cables rely on their large and uniform distribution to monitor the temperature inside the grain storage with high precision. However, these cables can only monitor the temperature inside the grain storage environment and cannot monitor the gas composition inside the cables. Therefore, it is often necessary to install gas sensors at different locations inside the grain storage to detect the gas composition. However, installing gas sensors inside the grain storage not only increases the workload of workers inserting the gas sensors into the grain storage, but also increases the workload of removing the sensors during subsequent grain unloading. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, temperature measuring cables and gas sensors need to be separately inserted into the grain storage to monitor temperature and gas composition, which increases the workload of staff. This invention provides a sensing component for detecting the state of grain storage.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention adopts the following technical solution: a sensing component for detecting the state of stored grain, comprising a temperature measuring cable and multiple connecting shells evenly disposed on the temperature measuring cable.

[0006] The connecting shell includes two sets of interlocking inner shells and outer shells. Multiple countersunk holes are provided at the edges of both sets of inner shells and outer shells. The two sets of countersunk holes are connected by fasteners to lock the connecting shell onto the temperature measuring cable.

[0007] Each set of inner and outer shells forms a monitoring cavity for mounting a gas sensor, and the outer shell has multiple through holes connecting the outside to the monitoring cavity.

[0008] As a further optimization of the sensing component for detecting the state of stored grain of this utility model: the inner shell is rotatably connected to the temperature measuring cable, and the surface of the outer shell is provided with a spiral strip.

[0009] As a further optimization of the sensing component for detecting the state of grain storage of this utility model: multiple annular grooves are provided on the inner shell, and a snap ring for snapping the temperature measuring cable is rotatably connected in the annular groove.

[0010] As a further optimization of the sensing component for detecting the state of grain storage according to this utility model: the snap ring is C-shaped.

[0011] As a further optimization of the sensing component for detecting the state of stored grain according to this utility model: through holes are distributed between the spiral spacing of the spiral strip.

[0012] As a further optimization of the sensing component for detecting the state of stored grain according to this utility model: the through hole is set at an angle.

[0013] As a further optimization of the sensing component for detecting the state of grain storage of this utility model: the monitoring cavity is provided with a plurality of reinforcing plates fixed on the inner shell and pressing against the outer shell.

[0014] As a further optimization of the sensing component for detecting the state of grain storage of this utility model: the cross-section of the two sets of two outer shells connected by fasteners is set in a spindle shape.

[0015] As a further optimization of the sensing component for detecting the state of grain storage according to this utility model: the fastener is a bolt and nut structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention uses two sets of inner and outer shells with countersunk holes at their edges to fit fasteners, including bolts and nuts, to position the two sets of inner and outer shells onto the temperature measuring cable. After repeated installation, two sets of inner and outer shells can be installed at corresponding positions on the temperature measuring cable. This allows the gas sensors, monitoring chambers, and corresponding through holes on the inner shells to be evenly distributed onto the temperature measuring cable. When the temperature measuring cable is installed inside the stored grain, multiple gas sensors can be simultaneously and evenly distributed inside the stored grain.

[0018] Furthermore, this utility model, by setting an annular groove on the inner shell and a snap ring that cooperates with the annular groove, allows the connecting shell to rotate at the corresponding position of the temperature measuring cable. At the same time, in conjunction with the spiral strip on the outer shell, when the connecting shell is inserted into or pulled out of the stored grain, the outward pushing force of the grain into the connecting shell can be converted into a force in the direction of rotation of the connecting shell, thereby reducing the resistance during the process of inserting or pulling out the temperature measuring cable with the connecting shell, and thus reducing the workload of the workers.

[0024] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0025] like Figure 1-3 As shown, a sensing component for detecting the state of stored grain includes a connecting shell 1 for locking onto a temperature measuring cable 8, so that the connecting shell 1 is evenly distributed on the temperature measuring cable 8, and then can be input into the stored grain along with the temperature measuring cable 8 to achieve uniform distribution within the stored grain.

[0026] The connecting shell 1 includes two sets of interlocking inner shells 102 and outer shells 101. Specifically, the inner wall of the inner shell 102 is annular, and the cross-section of the combined outer shells 101 is a vertical trapezoid to reduce friction with the grain when it enters the storage area. The outer periphery of the connecting shell 1 is spindle-shaped, further reducing the workload of the operator in inserting the temperature measuring cable 8 into the storage area. Multiple countersunk holes 103 are provided at the edges of the inner shell 102 and outer shell 101. The two sets of countersunk holes 103 can be used with fasteners 7 to clamp the temperature measuring cable 8 onto its outer periphery, allowing multiple connecting shells 1 to be evenly distributed onto the temperature measuring cable 8. Specifically, the fasteners 7 are bolt and nut structures. A monitoring cavity 3 is formed between the monitoring chambers to maintain a slow change in the air composition within the monitoring space. A through hole 5 communicating with the monitoring cavity 3 is provided on the outer shell 101. Specifically, the through hole 5 is set as an inclined hole to reduce the probability of grain entering through the through hole 5 and affecting the monitoring sensitivity of the gas sensor 6. The inner shell 102 is equipped with the gas sensor 6 and multiple reinforcing plates 4. The signal output circuit of the gas sensor 6 passes through the inner shell 102 and is distributed along the temperature measuring cable 8. The gas sensor 6 can work with the monitoring cavity 3 to stably detect the air composition, that is, to detect the air in the corresponding environment. The reinforcing plates 4 can contact the inner wall of the outer shell 101 to maintain the stability of the overall structure of the connecting shell 1.

[0027] like Figure 4As shown, the inner wall of the inner shell 102 is provided with a locking post 10, and the inner wall of the outer shell 101 is provided with a locking frame 9 that cooperates with the locking post 10. Specifically, the locking post 10 is L-shaped, the width of the locking hole of the locking frame 9 is the maximum width of the locking post 10, and the length of the locking hole is the distance from the inner wall of the inner shell 102 to the bend of the locking post 10. One side wall of the locking frame 9 is flush with the bend of the locking post 10. After the locking post 10 is inserted into the locking frame 9, the bend of the locking post 10 will fit against the side of the locking frame 9 away from the inner shell 102, thereby positioning the locking post 10 to maintain a tight connection between the inner shell 102 and the outer shell 101. Then, the fastener 7 can pass through the two sets of countersunk holes 103 opened on the corresponding two sets of inner shell 102 and outer shell 101 to lock the connecting shell 1 onto the temperature measuring cable 8 for use.

[0028] Multiple annular grooves 201 are formed on the inner wall of the inner shell 102. The annular grooves 201 are fitted with snap rings 202. The snap rings 202 are C-shaped to facilitate snapping onto the temperature measuring cable 8 for assembly. The fit between the snap rings 202 and the annular grooves 201 allows the inner shell 102 and the outer shell 101 to rotate. A spiral strip 203 is provided on the surface of the outer shell 101. When the connecting shell 1 is inserted into the stored grain along with the temperature measuring cable 8 to detect the uniformity of the internal environment of the stored grain, the vertical thrust of the grain that is blocking the connecting shell 1 from entering is converted into an axial force in the direction of rotation of the connecting shell 1 by the rotation of the spiral strip 203 and the connecting shell 1. This further reduces the resistance of the connecting shell 1 entering the stored grain. Specifically, through holes 5 are provided between the thread spacing of the spiral strip 203 to increase the gap between the through holes 5 and the grain, so that the air inside the stored grain can fully enter the monitoring chamber 3 for monitoring by the gas sensor 6.

[0029] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
