Description

Technical Field

[0001] This utility model relates to the field of temperature measuring cables, and in particular to a novel flange-fixed silo temperature measuring cable. Background Technology

[0002] Grain warehouses need to monitor the temperature of the grain inside during specific periods. The common practice is to vertically install multiple temperature measuring cables inside the grain warehouse to monitor changes in grain conditions. When the grain temperature rises abnormally, timely fumigation, pest control, ventilation, and temperature control can be implemented to avoid affecting grain safety and causing economic losses.

[0003] Existing temperature measuring cables typically have temperature sensors installed inside to monitor changes in grain temperature within the grain silo. However, these cables have a limited function, only detecting temperature changes. When the grain temperature changes, it indicates that the grain is already in the process of spoilage, requiring timely treatment. Spoilage often occurs deep within the grain pile, taking considerable time to process, and delays can lead to even greater losses. Furthermore, existing temperature measuring cables are prone to damage over extended periods. Therefore, there is an urgent need for a temperature measuring cable that can not only monitor grain conditions but also perform preliminary treatment to prevent further spoilage, while also being durable and resistant to damage. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of flange-fixed silo temperature measuring cable in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A novel flange-fixed silo temperature measuring cable includes an outer sheath and a flange. One end of the outer sheath is fixedly connected to the flange, and the other end of the outer sheath is fixedly connected to a sealing sleeve. An elongated hole is formed in the outer sheath along its length. Two steel strands are symmetrically fixed in the outer sheath along the elongated hole. A cable sleeve and a gas guide tube are inserted into the elongated hole, and a temperature measuring cable is installed in the cable sleeve.

[0007] Preferably, the flange includes a flange sleeve, a flange core, and a flange cover. The flange core is installed inside the flange sleeve, and the outer contour of the flange core matches the inner wall of the flange sleeve. The outer wall of the flange core has a limiting groove that matches the air guide pipe and two fixing grooves that match the steel strand symmetrically along the axial direction. The flange core has a through groove that matches the temperature measuring cable along the axial direction. The flange cover is fixedly connected to the flange plate on the flange sleeve by bolts, and the flange cover has through holes at the opposite ends of the through groove and the limiting groove.

[0008] With this setup, the steel strands can be fixed and pressed into the corresponding fixing grooves by combining the flange sleeve, flange core, and flange cover, thereby connecting the outer sheath and the flange into a whole. The air guide pipe can be fixed in the limiting groove to prevent it from being squeezed. It is also very convenient to replace the air guide pipe and the temperature measuring cable when they are damaged.

[0009] Preferably, a waterproof connector is fixedly installed on the outer flange cover at the position opposite to the through hole;

[0010] With this setup, the temperature measuring cable and the air duct can be fixed to the flange cover by the threaded tightening nut on the waterproof connector, preventing them from coming loose during use and also preventing dust and other impurities from entering the flange sleeve.

[0011] Preferably, the flange sleeve has an installation groove that matches the outer contour of the outer sheath tube at the connection point with the outer sheath tube;

[0012] This design allows for a tighter and easier connection between the flange and the outer sheath.

[0013] Preferably, a sealing connection sleeve is fitted together on the outer wall of the connection between the flange sleeve and the outer sheath tube;

[0014] This design makes the connection between the flange and the outer sheath more secure and stable, and also further prevents dust and other impurities from entering the outer sheath and the flange.

[0015] Preferably, after the free end of one of the steel strands inside the outer sheath is bent, it is squeezed and fixed by the sealing sleeve to form a steel wire ring;

[0016] This configuration facilitates the use of the device.

[0017] Preferably, the sealing sleeve has a through hole for the end of the air guide tube to pass through, and a waterproof connector is fixedly installed on the sealing sleeve at the through hole, and a tightening nut is threadedly matched on the waterproof connector.

[0018] With this setup, the air duct can be fixed to the sealing sleeve by using the tightening nut with matching threads on the waterproof connector, preventing it from coming off during use and also preventing dust and other impurities from entering the outer sheath.

[0019] Preferably, the number of elongated holes is one or two. When the number of elongated holes is two, the elongated holes may or may not be connected.

[0020] This setup facilitates the installation and use of temperature measuring cables and air ducts.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. The design of the temperature measuring cable and air duct inside the outer sheath not only protects the temperature measuring cable and air duct from damage, but also allows nitrogen to be blown into the grain at the detection point to isolate the air when the temperature measuring cable detects a change in the grain condition. This effectively prevents the grain from further deteriorating, buys more time for subsequent processing, and can effectively prevent greater losses.

[0023] 2. The outer sheath and the flange can be connected as a whole through the flange, which makes it very convenient to replace the air duct and temperature measuring cable when they are damaged.

[0024] 3. The waterproof connector can fix one end of the temperature measuring cable and the air duct to the outer flange cover, and the other end of the air duct to the sealing sleeve. This can prevent them from coming off during use and can also prevent dust and other impurities from entering the outer sheath and flange. Attached Figure Description

[0036] Example 1

[0037] like Figure 1-5 As shown, a novel flange-fixed silo temperature measuring cable includes an outer sheath 1 and a flange. One end of the outer sheath 1 is fixedly connected to the flange, and the other end of the outer sheath 1 is fixedly connected to a sealing sleeve 14. An elongated hole 2 is opened in the outer sheath 1 along its length. Two steel strands 11 are symmetrically fixed in the outer sheath 1 along the elongated hole 2. A cable sleeve 3 and a gas guide pipe 5 are inserted into the elongated hole 2. A temperature measuring cable 4 is installed in the cable sleeve 3.

[0038] Preferably, the flange includes a flange sleeve 6, a flange core 7, and a flange cover 10. The flange core 7 is installed inside the flange sleeve 6, and the outer contour of the flange core 7 matches the inner wall of the flange sleeve 6. The outer wall of the flange core 7 has a limiting groove 9 that matches the air guide pipe 5 and two fixing grooves 8 that match the steel strand 11 symmetrically along the axial direction. The flange core 7 has a through groove 12 that matches the temperature measuring cable 4 along the axial direction. The flange cover 10 is fixedly connected to the flange plate on the flange sleeve 6 by bolts. The flange cover 10 has through holes at the opposite ends of the through groove 12 and the limiting groove 9. With this arrangement, the steel strand 11 can be fixedly pressed into the corresponding fixing grooves 8 by the combination of the flange sleeve 6, the flange core 7, and the flange cover 10, thereby connecting the outer sheath pipe 1 and the flange into a whole. The air guide pipe 5 can be fixed in the limiting groove 9 to prevent it from being squeezed. It is also very convenient to replace the air guide pipe 5 and the temperature measuring cable 4 when they are damaged.

[0039] Waterproof connectors 13 are fixedly installed on the outer flange cover 10 at the positions opposite to the through holes. The waterproof connectors 13 are threaded with tightening nuts. With this arrangement, the temperature measuring cable 4 and the air duct 5 can be fixed to the outer flange cover 10 by using the tightening nuts on the waterproof connectors 13 to prevent them from coming off during use. It can also prevent dust and other impurities from entering the flange sleeve 6.

[0040] The flange sleeve 6 has an installation groove 16 that matches the outer contour of the outer sheath tube 1 at the connection point with the outer sheath tube 1. This design makes the connection between the flange sleeve 6 and the outer sheath tube 1 tighter and easier.

[0041] A sealing connection sleeve 15 is fitted together on the outer wall of the connection between the flange sleeve 6 and the outer sheath tube 1. This arrangement can further make the connection between the flange sleeve 6 and the outer sheath tube 1 more reliable and stable, and can also further prevent dust and other impurities from entering the outer sheath tube 1 and the flange.

[0042] One of the steel strands 11 inside the outer sheath 1 is bent at its free end and then squeezed and fixed by the sealing sleeve 14 to form a steel wire ring. This arrangement facilitates the use of this device.

[0043] The sealing sleeve 14 has a through hole for the end of the air guide tube 5 to pass through, and a waterproof connector 13 is fixedly installed on the sealing sleeve 14 relative to the through hole. With this arrangement, the air guide tube 5 can be fixed on the sealing sleeve 14 by using the tightening nut on the threaded fitting of the waterproof connector 13 to prevent it from falling off during use, and also to prevent dust and other impurities from entering the outer sheath tube 1.

[0044] The number of elongated holes 2 is one or two. When there are two elongated holes 2, they may be connected or not connected. This arrangement facilitates the installation and use of the temperature measuring cable 4 and the air duct 5.

[0045] Working principle:

[0046] By combining the flange sleeve 6, flange core 7 and flange cover 10, the steel strands 11 can be fixed and pressed into the corresponding fixing grooves 8, thereby connecting the outer sheath tube 1 and the flange into a whole, while the air guide tube 5 can be fixed in the limiting groove 9 to prevent it from being squeezed.

[0047] The waterproof connector 13 can be used to fix one end of the temperature measuring cable 4 and the air duct 5 to the flange cover 10, and the other end of the air duct 5 to the sealing sleeve 14 to prevent them from falling off during use.

[0048] This design makes it very convenient to replace the air duct 5 and the temperature measuring cable 4 when they are damaged.

[0049] At the end of the air duct 5 furthest from the detection end, a nitrogen filling pump is connected via a conduit. The design of the air duct 5 inside the outer sheath 1 and the temperature measuring cable 4 not only protects the temperature measuring cable 4 and the air duct 5 from damage, but also allows nitrogen to be blown into the grain at the detection point through the air duct 5 when the temperature measuring cable 4 detects a change in grain condition, effectively preventing further deterioration of the grain and buying more time for subsequent processing. This design is of great significance in grain condition detection and effective control.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
