Technical Field
[0001] The utility model belongs to the technical field related to logistics, and particularly relates to a temperature-sensitive and gas-sensitive sensor applied to a container. Background Technique
[0002] In the modern logistics and transportation industries, environmental monitoring of containers has become particularly important. Especially for goods sensitive to temperature and gas changes, such as food, medicine, and chemicals, ensuring environmental stability during transportation is crucial for protecting the quality of the goods. For this purpose, an advanced container temperature-sensitive and gas-sensitive sensor system has been developed;
[0003] This system mainly consists of a sensor host, a temperature-sensitive probe, and a gas-sensitive probe. The sensor host is connected to the temperature-sensitive connector and the gas-sensitive connector through the connector jack at its top, and these connectors are connected to the temperature-sensitive probe and the gas-sensitive probe through wires. An electronic control unit, a data processing module, and a communication interface are integrated inside the sensor host, which can receive and process temperature and gas data from the probes in real time. The data display screen provides real-time monitoring information, and the control buttons allow users to perform system settings and operations. The temperature-sensitive probe accurately measures the temperature changes inside the container through technologies such as thermocouples or thermistors, and the gas-sensitive probe detects gas components through chemical reactions or electrochemical reactions. Through real-time monitoring and data processing, the sensor system can not only display temperature and gas information in a timely manner but also trigger an alarm when an abnormality is detected, thus effectively preventing damage to goods caused by environmental factors or potential safety hazards.
[0004] However, the temperature-sensitive and gas-sensitive sensor applied to a container mainly consists of a host and multiple probes. The host is installed on the outer wall of the container, and the multiple probes are connected to the internal environment of the container, enabling the probes to detect the internal environment of the container in real time. Since the main uniform routes of containers are shipping and land transportation, containers are mostly in direct contact with the external environment. In rainy weather, rainwater will directly pour on the connection between the host and the probe wires, which can easily cause rainwater to penetrate into the interior of the connection between the host and the probe wires, easily resulting in unstable power supply and short circuit situations, thereby causing the probes to lose their functions or the information detected by the probes not to be transmitted back to the host in a timely manner. Content of the Utility Model
[0005] The purpose of the utility model is to provide a temperature-sensitive and gas-sensitive sensor applied to a container to solve the problem that in most cases, the container is directly in contact with the external environment. In rainy weather, rainwater will directly pour on the connection between the host and the probe wires, which can easily cause rainwater to penetrate into the interior of the connection between the host and the probe wires, easily resulting in unstable power supply and short circuit situations, thereby causing the probes to lose their functions or the information detected by the probes not to be transmitted back to the host in a timely manner as mentioned in the above background technique.
[0006] To achieve the above object, the present utility model provides the following technical solutions: A temperature and gas sensitive sensor applied to a container, comprising a sensor main body and two connector jacks arranged inside the top end of the sensor main body. A temperature sensitive connector and a gas sensitive connector are respectively inserted into the two connector jacks. A temperature sensitive wire and a gas sensitive wire are respectively connected to the temperature sensitive connector and the gas sensitive connector. The other ends of the temperature sensitive wire and the gas sensitive wire are respectively connected to a temperature sensitive probe and a gas sensitive probe. An outdoor waterproof protection device is arranged outside the temperature sensitive connector and the gas sensitive connector;
[0007] The outdoor waterproof protection device includes a metal fixing strip, a waterproof sealing gasket, a waterproof protection cover and fixing screws. The waterproof sealing gasket is adhesively fixed to the outer wall of the bottom end of the waterproof protection cover. Metal fixing strips are welded to the outer walls of the left and right ends of the bottom of the waterproof protection cover. The two metal fixing strips are fixed to the top end of the sensor main body by the fixing screws.
[0008] Preferably, both the upper and lower ends of the waterproof protection cover are open. The waterproof protection cover is made of aluminum alloy. The outer wall of the bottom end of the waterproof sealing gasket can be closely attached to the outer wall of the top end of the sensor main body.
[0009] Preferably, the outdoor waterproof protection device further includes an elastic rubber sealing piece and a self - shrinking wire hole. The elastic rubber sealing piece is fixed inside the top opening of the waterproof protection cover. A plurality of self - shrinking wire holes are arranged inside the elastic rubber sealing piece, and the self - shrinking wire holes are sleeved outside the temperature sensitive wire and the gas sensitive wire.
[0010] Preferably, the elastic rubber sealing piece is fixedly connected to the waterproof protection cover by an adhesive, and the connection between the elastic rubber sealing piece and the waterproof protection cover is also encrypted by a waterproof sealant. The holes of the self - shrinking wire holes can automatically shrink and be in a closed state when not in use.
[0011] Preferably, a main body back plate is arranged at the rear end of the sensor main body. The main body back plate is fixedly connected to the sensor main body by a plurality of embedded screws. Main body mounting blocks are arranged at both the left and right ends of the main body back plate.
[0012] Preferably, a data display screen is arranged inside the front end of the sensor main body. A transparent protective film is also adhered to the outer wall of the front end of the data display screen. A plurality of control buttons are arranged below the data display screen.
[0013] Preferably, fixing flanges are arranged outside the bottom ends of the temperature sensitive probe and the gas sensitive probe, and the temperature sensitive probe and the gas sensitive probe are both installed and fixed on the container through the fixing flanges and screws.
[0014] Compared with the prior art, the present utility model provides a temperature and gas sensitive sensor applied to a container, having the following beneficial effects:
[0015] The utility model adds a new outdoor waterproof protection device to the top of the main body of the temperature-sensitive and gas-sensitive sensor applied to a container. The outdoor waterproof protection device protects the temperature-sensitive connector and the gas-sensitive connector outside the top of the sensor main body. After the sensor main body is installed on the outer wall of the container, since the sensor main body is completely exposed on the outer wall of the container and in contact with the external environment, it is vulnerable to wind and rain erosion. The outdoor waterproof protection device can play a waterproof protection role at the connection between the temperature-sensitive connector and the gas-sensitive connector and the sensor main body, avoiding the situation that rainwater directly erodes the connection between the temperature-sensitive connector and the gas-sensitive connector and the sensor main body during shipping or land transportation, which is likely to cause a short circuit, and ensuring that the temperature-sensitive probe and the gas-sensitive probe can be normally electrically connected to the sensor main body through wires and connectors, so that the sensor main body can monitor the temperature and gas conditions inside the container in real time through the temperature-sensitive probe and the gas-sensitive probe.

Detailed Embodiment
[0021] 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.
[0022] The present utility model provides asFigures 1-4 A temperature - sensitive and gas - sensitive sensor applied to a container, as shown, includes a sensor main body 1 and two connector jacks arranged inside the top end of the sensor main body 1. A temperature - sensitive connector 11 and a gas - sensitive connector 12 are respectively inserted into the two connector jacks. A temperature - sensitive wire 6 and a gas - sensitive wire 7 are respectively connected to the temperature - sensitive connector 11 and the gas - sensitive connector 12. The other ends of the temperature - sensitive wire 6 and the gas - sensitive wire 7 are respectively connected to a temperature - sensitive probe 9 and a gas - sensitive probe 10. A main body backplane 4 is arranged at the rear end of the sensor main body 1. The main body backplane 4 is fixedly connected to the sensor main body 1 through a plurality of embedded screws. Main body mounting blocks 5 are arranged at both the left and right ends of the main body backplane 4. A data display screen 3 is arranged inside the front end of the sensor main body 1. A transparent protective film is also pasted on the front outer wall of the data display screen 3. A plurality of control buttons 2 are arranged below the data display screen 3. Fixed flanges are arranged outside the bottoms of the temperature - sensitive probe 9 and the gas - sensitive probe 10. And the temperature - sensitive probe 9 and the gas - sensitive probe 10 are both installed and fixed on the container through the fixed flanges and screws. When installing and using this temperature - sensitive and gas - sensitive sensor applied to a container, first, it is necessary to determine the installation position of the sensor main body 1 on the outer wall of the container. Then, it is necessary to fit the main body backplane 4 to the installation position on the outer wall of the container and use screws to install and fix the main body mounting blocks 5 on the container. Then, it is necessary to insert the temperature - sensitive connector 11 and the gas - sensitive connector 12 into the connector jacks inside the top end of the sensor main body 1 respectively. Then, it is necessary to insert both the temperature - sensitive probe 9 and the gas - sensitive probe 10 into the holes reserved on the container and use screws and flanges to firmly fix both the temperature - sensitive probe 9 and the gas - sensitive probe 10 on the container, so that the temperature - sensitive probe 9 and the gas - sensitive probe 10 can detect the internal environment of the container in real time.
[0023] As Figure 1 、 Figure 2 and Figure 3As shown, the sensor host 1 is the core component of the system. Inside the host, there are an electronic control unit, a data processing module, and a communication interface. Its function is to receive and process signals from the probe and transmit the processing results to the user interface or other systems. Among them, the temperature-sensitive probe 9 is specifically used to detect the temperature inside the container. Its working principle is based on technologies such as thermocouples, thermistors, or resistance temperature detectors. The probe measures the temperature change through the exchange of heat with the environment. The sensing element inside the probe generates a voltage change or a resistance change with the temperature change. This voltage or resistance change is collected by the electronic control unit of the sensor host 1 and converted into readable temperature data. The temperature data is transmitted through the communication interface of the host to the data processing module or an external system for further analysis and monitoring. At the same time, the temperature information can be displayed in real time on the data display screen 3. The gas-sensitive probe 10 is used to detect the gas composition inside the container. Its working principle is usually based on chemical reactions or electrochemical reactions. The surface of the gas-sensitive probe 10 is coated with sensitive materials. These materials undergo chemical reactions or adsorption with gas molecules in the air. Different gases cause changes in the conductivity or voltage of the sensitive materials. The sensing element inside the probe converts this change into an electrical signal, usually a voltage or current signal. The sensor host 1 collects these signals and converts them into gas concentration data through the data processing module. These data can display information such as gas concentration and type, and the detected gas information is also displayed in real time on the data display screen 3. This integrated temperature-sensitive and gas-sensitive sensor system is widely used in container transportation, especially for goods that are sensitive to temperature and gas changes. Through real-time monitoring, it can effectively protect the quality of the goods and prevent damage or safety hazards caused by environmental factors.
[0024] As Figure 1 , Figure 3 and Figure 4As shown, an outdoor waterproof protection device 8 is provided outside the temperature-sensitive connector 11 and the gas-sensitive connector 12. The outdoor waterproof protection device 8 includes a metal fixing strip 13, a waterproof gasket 14, a waterproof protection cover 15, and fixing screws 18. A waterproof gasket 14 is adhesively fixed to the outer wall of the bottom end of the waterproof protection cover 15. Metal fixing strips 13 are welded to the outer walls of the left and right ends of the bottom of the waterproof protection cover 15. Both metal fixing strips 13 are fixed to the top end of the sensor main body 1 by fixing screws 18. Both the upper and lower ends of the waterproof protection cover 15 are open. The waterproof protection cover 15 is made of aluminum alloy. The outer wall of the bottom end of the waterproof gasket 14 can closely adhere to the outer wall of the top end of the sensor main body 1. The outdoor waterproof protection device 8 further includes an elastic rubber sealing piece 16 and a self-shrinking wire hole 17. An elastic rubber sealing piece 16 is fixed inside the top opening of the waterproof protection cover 15. A plurality of self-shrinking wire holes 17 are provided inside the elastic rubber sealing piece 16, and the self-shrinking wire holes 17 are sleeved outside the temperature-sensitive wire 6 and the gas-sensitive wire 7. The elastic rubber sealing piece 16 is fixedly connected to the waterproof protection cover 15 by an adhesive, and the connection between the elastic rubber sealing piece 16 and the waterproof protection cover 15 is also encrypted by a waterproof sealant. When the self-shrinking wire holes 17 are not in use, the holes can automatically shrink and be in a closed state.
[0025] As Figure 1 , Figure 3 and Figure 4 shown, before the temperature-sensitive connector 11 and the gas-sensitive connector 12 on the temperature-sensitive wire 6 and the gas-sensitive wire 7 need to be inserted into the connector jacks inside the top end of the sensor main body 1, first, it is necessary to use a flaring pliers to expand the self-shrinking wire holes 17 inside the elastic rubber sealing piece 16 outward, then maintain the expanded state and pass the temperature-sensitive connector 11 and the gas-sensitive connector 12 through the self-shrinking wire holes 17, and then normally insert the temperature-sensitive connector 11 and the gas-sensitive connector 12 into the connector jacks inside the top end of the sensor main body 1 respectively. Then move the waterproof protection cover 15 towards the outer wall of the top end of the waterproof main body until the waterproof protection cover 15 adheres to the outer wall of the top end of the sensor main body 1 through the waterproof gasket 14 at the bottom end, and use screws to fix the metal fixing strips 13 at the left and right ends of the waterproof protection cover 15 to the top end of the sensor main body 1, so that the waterproof gasket 14 at the bottom end of the waterproof protection cover 15 closely adheres to the outer wall of the top end of the sensor main body 1 and forms a sealing effect, and release the flaring pliers. At this time, the elastic rubber sealing piece 16 will automatically shrink the self-shrinking wire holes 17 through the elasticity of its own material, so that the self-shrinking wire holes 17 firmly bind to the outer walls of the temperature-sensitive wire 6 and the gas-sensitive wire 7 and form a sealing effect. In this way, the waterproof protection cover 15 will separate the connection between the temperature-sensitive connector 11 and the gas-sensitive connector 12 from the external environment, thereby preventing rainwater and external air from invading into the inside of the waterproof protection cover 15, and thus being able to play a waterproof protection role for the connection part.
[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
