Description

Technical Field

[0001] This application relates to the technical field of small container testing, and particularly to a container status monitoring device. Background Art

[0002] When conducting tests such as fire burning and dropping on small containers, it is necessary to monitor key parameters inside the containers, such as temperature and acceleration. However, due to the small volume of small containers, the internal space is narrow. For example, the inner diameter of the container is only about 160 mm, and the depth is about 500 mm, leaving only enough space for one-handed operation. The channel pipelines are also relatively narrow, and strict sealing must be ensured, which makes it impossible to install conventional monitoring devices at all. Moreover, small containers usually only have a top opening and a bottom drain port, and the number of interfaces that can penetrate the inside of the container for the installation of the monitoring system is scarce. There are also usually structures such as fins and protective sleeves configured outside the container, which further increases the difficulty of setting up the monitoring system on small containers.

[0003] Therefore, there is an urgent need to develop a brand-new monitoring system and related technical solutions suitable for small containers to meet the monitoring requirements of such tests. Summary of the Invention

[0004] The purpose of the present invention is to provide a container status monitoring device that can be used for status monitoring of tests such as fire burning and dropping on small containers.

[0035] The present application provides a container status monitoring device for being installed on a small container to monitor the status of the small container undergoing fire and drop tests.

[0036] As Figure 1 and Figure 2 shown, the container status monitoring device provided by this application includes a first communication joint, a conduit 4, a pipe joint 5, a sensor 2, and a monitoring device 3.

[0037] The small container 1 to be tested includes an inner shell 11 and an outer shell 12. The outer shell 12 is sleeved outside the inner shell 11. A drain pipe 15 is provided at the bottom of the inner shell 11, and the drain pipe 15 forms an outlet at the bottom of the side wall of the outer shell 12.

[0038] The first communication joint 6 is provided outside the container 1. The probe of the sensor 2 is provided inside the container 1 (specifically, the inner shell). The cable of the sensor 2 extends out of the container 1 through the drain pipe 15 of the container 1 to be electrically connected to the terminal of the first communication joint 6, and is electrically connected to the monitoring device 3 through the first communication joint 6, so that the parameters inside the container 1 detected by the sensor 2 during the test process can be uploaded to the monitoring device 3 for data storage and analysis.

[0039] The first communication joint 6 is installed at the outlet of the drain pipe 15 of the container 1 through the conduit 4; specifically, as Figure 2 and Figure 3 shown, one end of the conduit 4, that is, the first end of the conduit 4, is communicated with a pipe joint 5. The first end of the conduit 4 can be detachably and sealingly communicated to the outlet of the drain pipe 15 through the pipe joint 5, so that the cable of the sensor 2 can extend into the conduit 4 through the drain pipe 15. The other end of the conduit 4, that is, the second end of the conduit 4, is hermetically connected to the housing of the first communication joint 6, for example, by welding, and the port of the second end of the conduit 4 surrounds the terminal of the first communication joint 6; during specific assembly, the cable of the sensor 2 can be first led out from the second end of the conduit 4 and electrically connected to the terminal of the first communication joint 6, and then the first communication joint 6 and the conduit 4 are welded. Thus, not only the installation of the monitoring device on the container 1 can be completed conveniently and quickly, but also the sealing performance of the container 1 during the test can be effectively guaranteed.

[0040] In this embodiment, fins 13 are provided outside the container 1, and at the same time, a protective sleeve 14 needs to be sleeved outside the container 1; in this application, the second end of the conduit 4 is bent by a predetermined angle relative to the first end of the conduit 4, so that the second end of the conduit 4 extends along the height direction of the container 1 towards the top of the container 1, thereby effectively reducing the installation space of the monitoring device outside the container 1, so that the monitoring device can be located in the gap between the container 1 and the protective sleeve 14 to be applicable to the test and monitoring of the small container 1.

[0041] In an embodiment of this application, as Figure 2 and Figure 3As shown, a connecting seat 16 is provided at the outlet of the liquid discharge pipe 15 of the container 1. The connecting seat 16 is used to detachably connect with the pipe joint 5, so as to realize the sealed connection of the liquid discharge pipe 15 and the conduit 4.

[0042] Specifically, an opening is provided at the bottom of the side wall of the outer shell 12 of the container 1. One end of the connecting seat 16 is welded to this opening to be exposed outside the container 1, and the other end of the connecting seat 16 is welded to the outlet of the liquid discharge pipe 15. A first sink is provided at one end of the connecting seat 16 facing the outside of the container 1. A second sink is provided at the bottom of the first sink. The second sink is coaxial with the first sink, and the diameter of the second sink is smaller than that of the first sink; a first hole is provided at the bottom of the second sink. The first hole penetrates through one end of the connecting seat 16 facing the liquid discharge pipe 15 and is connected to the liquid discharge pipe 15.

One end of the pipe joint 5 is welded to the first end of the conduit 4, and the second hole is connected to the conduit 4; the end of the pipe joint 5 for connecting with the conduit 4 forms a connecting portion 51, and the pipe joint 5 forms a sealing portion 52 on the side of the connecting portion 51 away from the conduit 4. The diameter of the sealing portion 52 is smaller than that of the connecting portion 51, making the pipe joint 5 as a whole in a T shape.

[0044] When the pipe joint 5 is installed with the connecting seat 16, the sealing portion 52 can be fitted into the second sink, and the connecting portion 51 can be fitted into the first sink and abutted against the bottom of the first sink. Among them, a plurality of first connection holes are formed around the second sink at the bottom of the first sink, and a plurality of second connection holes are provided on the connecting portion 51. The plurality of second connection holes are arranged in one-to-one correspondence with the plurality of first connection holes, so as to be able to penetrate fasteners (such as bolts), thereby detachably connecting the pipe joint 5 and the connecting seat 16 by using the fasteners. At the same time, a sealing groove is provided on the outer side wall of the sealing portion 52. The sealing groove is arranged around the circumference of the sealing portion 52, and a sealing ring 53 is installed in the sealing groove, so that the outer side wall of the sealing portion 52 is in sealing abutment with the inner side wall of the second sink through the sealing ring 53, thereby ensuring the sealing of the connection between the pipe joint 5 and the connecting seat 16, and making the conduit 4 and the outlet of the liquid discharge pipe 15 of the container 1 in sealed connection.

[0045] In this embodiment, preferably, a plurality of sealing grooves are provided at intervals along the axial direction of the sealing portion 52 on the sealing portion 52, and a sealing ring 53 is installed in each sealing groove, so as to further improve the assembly sealing between the pipe joint 5 and the connecting seat 16 through multiple sealing rings 53.

[0046] In an embodiment of the present application, preferably, as Figure 1 and Figure 2As shown in the figure, a second communication connector 7 is provided on the monitoring device 3. The second communication connector 7 is electrically connected to the monitoring device 3 through a transmission cable 8, and the second communication connector 7 can be adaptively electrically connected to the first communication connector 6 to realize the electrical connection between the sensor 2 and the monitoring device 3, so that the data measured by the sensor 2 can be uploaded to the monitoring device 3.

[0047] In this embodiment, preferably, one of the first communication connector 6 and the second communication connector 7 is a high-temperature socket, and the other is a high-temperature plug, so that the first communication connector 6 and the second communication connector 7 can withstand the high-temperature environment during the fire test, and the first communication connector 6 and the second communication connector 7 are electrically connected by plugging and unplugging, which can quickly realize the connection and disconnection between the two.

[0048] In this embodiment, preferably, when a fire test is performed on the container 1, a hard metal tube, such as a stainless steel tube, is sleeved outside the transmission cable 8 of the second communication connector 7, and at the same time, a heat-resistant insulating layer is filled between the hard metal tube and the transmission cable 8. Thus, the second communication connector 7 is prevented from being damaged due to high temperature during the fire test, and the stability of signal transmission is ensured.

[0049] When a drop test is performed on the container 1, the transmission cable 8 of the second communication connector 7 uses a flexible cable that can be bent, and the length is selected according to the drop height, so as to avoid the transmission cable 8 of the second communication connector 7 affecting the drop of the container 1, and at the same time avoid the disconnection between the second communication connector 7 and the first communication connector 6, thereby ensuring the stability of signal transmission and the stability of the test.

[0050] In an embodiment of the present application, preferably, as described above, fins 13 are provided outside the container 1, and at the same time, a protective sleeve 14 needs to be sleeved outside the container 1 after the installation of the monitoring device is completed, so that the second communication connector 7 and part of the transmission cable 8 are also located between the container 1 and the protective sleeve 14.

[0051] In this embodiment, the cable of the second communication connector 7 extending between the container 1 and the protective sleeve 14 is arranged close to the fins 13 outside the container 1, and a rib plate is welded to the fins 13 to fix the transmission cable 8 of the second communication connector 7 by using the rib plate. Specifically, when a hard metal tube is sleeved outside the transmission cable 8, the hard metal tube is welded to the rib plate; when the transmission cable 8 is a flexible cable that can be bent, the transmission cable 8 is tied to the rib plate by using a binding member. Thus, the installation stability of the transmission cable 8 outside the container 1 is ensured, so as to ensure the connection stability between the first communication connector 6 and the second communication connector 7 during the test.
