Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of temperature measurement cable, in particular, to a replaceable core temperature, humidity and water integrated detection cable. BACKGROUND

[0002] In the warehouse industry, monitoring the temperature, humidity and moisture in the warehouse is crucial to ensure the storage quality of the materials in the warehouse. Especially in the field of grain storage, changes in temperature, humidity and moisture can cause grain to mold, deteriorate or cause insect infestation, affecting the quality and storage period of the grain. Detection cables have been widely used in the field of temperature, humidity and moisture detection in silos.

[0003] Detection cables are usually used in scenarios where the temperature, humidity and moisture of the environment need to be measured, and the cable has certain protection requirements. Silos are one of the application scenarios. In the silo, there may be friction of grain particles and corrosion of various storage gases, so the detection cable not only needs to measure temperature, humidity and moisture, but also needs to have good protection performance to ensure the accuracy of the measurement data and the service life of the equipment.

[0004] In order to protect the internal chip and other components for detection, the outer sheath is usually designed to have good protection performance and is made of high-strength and corrosion-resistant materials. However, when the internal chip fails, such as being corroded by certain corrosive gases in the silo, or needs to be replaced by another type of chip due to changes in measurement requirements, the chip and the outer sheath often have to be replaced as a whole. This means that after replacement, on the one hand, the positioning structure between the outer sheath and the inner wall of the silo needs to be reconfigured, increasing the complexity of replacement; on the other hand, the outer sheath is usually expensive, and the overall replacement increases the cost.

[0005] Therefore, there is an urgent need to develop a temperature, humidity and water integrated detection cable structure to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0037] The disclosure will be further described below in conjunction with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the disclosure, but not to limit the disclosure.

[0038] In order to make the drawing simple, only the parts related to the disclosure are shown in each figure, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0039] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the disclosure can be understood according to the specific circumstances.

[0040] In the disclosure, unless otherwise specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them.

[0042] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0043] As Figures 1-5 shown, which shows the replaceable core temperature and humidity integrated detection cable in an embodiment of the present disclosure, for installing in the silo to detect temperature, humidity and moisture data, including an outer sheath 1, the outer sheath 1 has an outer air hole 101; The inner core tube 2 is detachably arranged in the outer sheath 1, the inner core tube 2 is configured to be able to axially slide relative to the outer sheath 1 to insert or separate from the outer sheath 1, the inner core tube 2 has an inner air hole 201, the inner air hole 201 communicates with the outer air hole 101; The detection chip 4 is arranged in the inner core tube 2, which is used to detect the temperature, humidity and moisture data of the gas in the silo and transmit to the data acquisition device.

[0044] For example, as Figures 1-4 shown, when the silo is a grain storehouse, the outer sheath 1 can effectively resist the friction of the grain particles in the silo and the erosion of various storage gases, ensuring the good protection performance of the detection cable in the silo environment. The inner core tube 2 is made of light weight and certain strength engineering plastic. On the one hand, the inner core tube 2 is light in weight, which is convenient for operation when replacing, and on the other hand, it can provide protection for the internal wire 3 and detection chip 4. The connection between the inner core tube 2 and the outer sheath 1 adopts sliding fit, and the outer diameter of the inner core tube 2 is slightly smaller than the inner diameter of the outer sheath 1. The inner air hole 201 is distributed on the surface of the inner core tube 2, which ensures that the gas can enter the inner air hole 201 from the outer air hole 101 and contact the detection chip 4. The detection chip 4 can detect the temperature, humidity and moisture data of the gas in the silo. The detection chip 4 is connected with the external data acquisition device circuit through the line, which can connect the data acquisition device with the electronic equipment (such as computer), and obtain the detection data through the computer.

[0045] In actual application, the gas in the silo enters through the outer air hole 101 on the outer sheath 1, and then contacts the detection chip 4 through the inner air hole 201 on the inner core tube 2. The detection chip 4 detects the contacted gas and transmits the detected data to the external data acquisition device, so as to realize the detection of the temperature, humidity and moisture data in the silo. The detection chip 4 can be selected from the GXHT3WM-P chip produced by Beijing Zhongke Yinhelu Chip Technology Co., Ltd., which can realize the detection of temperature, humidity and moisture. When the detection chip 4 fails or needs to be replaced due to change of measurement demand, the operator only needs to axially pull out the inner core tube 2 from the outer sheath 1, replace the inner core tube 2 with a new detection chip 4 installed, and then insert it into the outer sheath 1, without replacing the outer sheath 1.

[0046] Through such a structural design, on the one hand, the design that the inner core pipe 2 is detachable and can axially slide relative to the outer sheath 1 makes the replacement of the detection chip 4 simple and convenient, without the need to reposition the structure between the outer sheath 1 and the inner wall of the silo, greatly reducing the complexity of the replacement operation. On the other hand, only the inner core pipe 2 is replaced without replacing the outer sheath 1, avoiding the problem of cost increase due to the high cost of the outer sheath 1, and reducing the maintenance cost.

[0047] In some examples, the inner core pipe 2 is provided with a wire 3 for circuit connection with a data acquisition device, and the detection chip 4 is arranged on the wire 3 and is circuit connected with the wire 3.

[0048] The detection chip 4 is a plurality of detection chips 4, and the plurality of detection chips 4 are respectively arranged at a plurality of height positions in the silo for detecting temperature, humidity and water data at the plurality of height positions in the silo.

[0049] The inner core pipe 2 has a glue hole 202 for injecting glue into the inner core pipe 2 and forming a partition 203 in the inner core pipe 2, and each detection chip 4 has a partition 203 on both sides.

[0050] For example, as shown in Figures 1-4 In this embodiment, the detection cable can be vertically installed in the silo, and a plurality of detection chips 4 are arranged in the inner core pipe 2 according to the height of the silo and the actual measurement requirement, and the plurality of detection chips 4 are respectively arranged at different height positions in the silo. The detection chip 4 detects the contacted gas and transmits the detected data to the external data acquisition device through the wire 3 to realize accurate detection of temperature, humidity and water data at different height positions in the silo.

[0051] The position of the glue hole 202 on the inner core pipe 2 corresponds to the upper and lower sides of each detection chip 4, and the glue hole 202 is used to inject sealing glue, such as epoxy resin glue, into the inner core pipe 2. The sealing glue fills the space on both sides of the detection chip 4 and solidifies to form a partition 203. The partition 203 separates the detection chips 4 at different heights, and also plays a role in strengthening the structure of the inner core pipe 2.

[0052] Because the gas conditions at different heights in the silo are different, the cable is vertically installed and a plurality of detection chips 4 at different heights are arranged, and each detection chip 4 corresponds to an inner air hole 201, so that each detection chip 4 can detect the temperature, humidity and water content of the gas at the height. By injecting glue into the inner core pipe 2 through the glue hole 202 to form a partition 203, the upper and lower sides of each detection chip 4 are separated, avoiding interference between the gases at different heights, ensuring that each detection chip 4 only detects the gas at its height, and thus improving the accuracy of the detection data.

[0053] The detection of data at different heights in the silo is realized. The operator can understand the distribution of temperature, humidity and moisture in the silo according to the data, and take measures in advance to prevent grain deterioration. The setting of the partition part 203 avoids the interference of gas at different heights on the detection result of the detection chip 4, and improves the reliability of the detection data. The partition part 203 formed by glue injection also enhances the structural stability of the inner core tube 2.

[0054] In some examples, a dustproof and breathable film 5 is attached to the inner core tube 2, and the dustproof and breathable film 5 covers the inner breathable hole 201 to filter the gas entering the inner core tube 2.

[0055] For example, as shown in Figures 1-4 The dustproof and breathable film 5 is attached to the surface of the inner core tube 2 and covers the inner breathable hole 201. In the silo environment, although the outer breathable hole 101 on the outer sheath 1 and the inner breathable hole 201 on the inner core tube 2 can allow gas to enter and contact the detection chip 4, various impurities in the environment may enter the inner core tube 2 along with the gas. The impurities entering may adhere to the surface of the detection chip 4, affecting the detection accuracy of the detection chip 4. By attaching the dustproof and breathable film 5 to the inner core tube 2, the gas entering the inner core tube 2 is filtered, ensuring normal gas entry while blocking impurities, providing a clean working environment for the detection chip 4.

[0056] The setting of the dustproof and breathable film 5 improves the reliability of the cable in the silo environment. It effectively prevents the pollution of the detection chip 4 by impurities, reduces the detection error caused by impurities, and ensures the accuracy of the data.

[0057] In some examples, sealing glue is coated at the contact point between the detection chip 4 and the wire 3.

[0058] For example, in order to solve the problem that the detection chip 4 in the cable is easily corroded by gas, a protective measure of coating sealing glue at the contact point between the detection chip 4 and the wire 3 is taken. There are many complex gas components in the silo, and some of them may be corrosive, which may erode the connection contact point of the detection chip 4 and the wire 3, affecting its normal work and service life. By coating sealing glue at the contact point between the detection chip 4 and the wire 3, the sealing glue is used to isolate the contact point from the corrosive gas, thereby protecting the stability of the detection chip 4 and its electrical connection. The measure of coating sealing glue improves the corrosion resistance of the detection chip 4, avoids the performance degradation and failure of the detection chip 4 caused by gas corrosion, ensures the accuracy of the detection data, and reduces the maintenance cost.

[0059] In some examples, a steel wire rope 6 is arranged inside the outer sheath 1, the steel wire rope 6 is arranged along the length direction of the outer sheath 1, and there are two steel wire ropes 6 arranged on both sides of the inner core tube 2.

[0060] For example, as shown in Figure 1 andFigure 2 As shown, high-strength galvanized steel wire ropes 6 are arranged inside the outer sheath 1. Two steel wire ropes 6 are arranged in parallel along the length direction of the outer sheath 1 and are located on both sides of the inner core tube 2. The steel wire ropes 6 arranged in the length direction are filled in the outer sheath 1 of the cable, and the steel wire ropes 6 serve as the main force-bearing component to disperse the tension and improve the structural strength of the cable. The arrangement of the steel wire ropes 6 enhances the structural strength of the cable. In actual application, the cable can resist tension from various directions, reduce the risk of damage to the cable caused by external force, and ensure the stability of data detection.

[0061] In some examples, the outer sheath 1 has an elliptical cross-sectional shape.

[0062] For example, as shown in Figure 1 and Figure 2 The cable with a traditional circular cross-sectional shape has a relatively large circumference and a large cross-sectional area when meeting the same internal space requirement. The elliptical cross-sectional shape reduces the cross-sectional area while ensuring that the inner core tube 2, the wire 3, and the detection chip 4 are accommodated. Compared with the traditional circular cross-sectional outer sheath 1, the elliptical cross-sectional outer sheath 1 saves material costs. Due to the reduced cross-sectional area, the required raw materials for production are reduced under the same production scale, thereby reducing the production cost.

[0063] In some examples, the elliptical cross-sectional outer sheath 1 has a long-axis direction and a short-axis direction, and the outer vent hole 101 is located on both sides of the long-axis direction of the outer sheath 1.

[0064] For example, as shown in Figures 1-4 In this embodiment, because the outer sheath 1 has an elliptical cross-sectional shape, the side surface area on both sides of the long-axis direction is relatively large, and the operation space is larger than that on the short-axis direction or other positions. The outer vent hole 101 is arranged at this position, which can make full use of the large side surface area, facilitate the hole opening operation, and reasonably plan the number and distribution of the vent holes while reducing the influence on the structural strength of the elliptical outer sheath 1.

[0065] In some examples, the inner vent holes 201 are arranged in a circumferential array in groups of several inner vent holes 201.

[0066] For example, as shown in Figure 5 In this embodiment, the inner vent holes 201 are arranged in a circumferential array in groups of several inner vent holes 201. The number of inner vent holes 201 in each group can be flexibly set according to actual requirements. The circumferential array arrangement enables the gas to enter the inner core tube 2 uniformly from multiple directions. The arrangement of the inner vent holes 201 can be adjusted according to requirements to improve the adaptability of the detection cable.

[0067] In some examples, the diameter of the steel wire rope 6 is one of 5 mm, 6 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm and 9 mm.

[0068] For example, steel wire ropes 6 of different diameters have different tensile strengths and flexibility. According to the actual needs of the cable during installation and use, the diameter of the steel wire rope 6 is reasonably selected to ensure that the cable can work stably in various silo environments.

[0069] In some examples, the end of the lead wire 3 is connected with a plug-in connector 7, which is used to connect with the circuit of the data acquisition device.

[0070] For example, as shown in Figure 1 The lead wire 3 is arranged to the plug-in connector 7, and the standard shape of the plug-in connector 7 makes it convenient and fast to plug with the data acquisition device to realize the circuit connection between them. This facilitates the connection operation between the cable and the data acquisition device, and improves the efficiency of installation and maintenance. The plug-in connector 7 ensures stable data transmission in the silo environment.

[0071] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure, not to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, and they should be covered in the scope of the claims of the present disclosure.
