Detailed ways

Figures 3a to 3c show the structure of the tank container of the present invention, the tank container has a valve protection box 20, its structure is basically the same as that of the existing tank container, the only difference is that the valve protection box An electronic monitoring device 30 is installed at a predetermined position in 20 . For example, the electronic monitoring device 30 can be installed on the inner wall near the opening of the protection box 20 , and the opening of the valve protection box 20 is provided with a seal 60 .

Referring to Fig. 1 and Fig. 2a to 2c, the electronic monitoring device 30 installed on the valve protection box 20 of the tank container 10 in the present invention is shown, and the electronic monitoring device 30 mainly includes: a sensor 35 (as shown in Fig. 4 shown), a data processing module 36 (as shown in FIG. 4 ), and a travel switch 31 with a contact 311. The travel switch 31 has a first position and a second position. In the first position, the contact 311 of the travel switch 31 is in contact with the cover 21 of the valve protection box 20, and the cover 21 presses the contact 311. , at this time the circuit in the travel switch 31 is conducting and working, that is, it is in a normal working state; in the second position, the contact 311 of the travel switch 31 is separated from the cover 21 of the valve protection box 20, and the travel The circuit in the switch 31 is closed, that is, it is in an abnormal working state. The travel switch 31 is mainly used for monitoring the illegal opening of the valve protection box, and its contact 311 is pressed when the lid 21 is closed. At this moment, the circuit in the travel switch 31 is conducted and works. Once the lid 21 is illegally opened and exceeds a predetermined safety distance of the travel switch, that is, the contact 311 breaks away from the lid 21, the travel switch 31 circuit becomes closed by conduction, and sends a signal to form a record or report to the police.

As shown in FIG. 4 , it shows a structural block diagram of the working principle of the present invention to realize illegal opening and leakage monitoring. Both the travel switch 31 and the sensor 35 are connected in communication with the data processing module 36, and are used to receive the opening and closing signal of the valve protection box 20 detected by the travel switch 31 and the concentration of the contents in the tank detected by the sensor 35. signal, and process, store and record. The data processing module 36 includes a signal acquisition and processing module 361 , a data storage and recording module 362 and a signal transmission module 363 . Preferably, the electronic detection device 30 can also be wired or wirelessly connected to a remote data terminal 80 . This signal acquisition and processing module 361 receives the data from travel switch 31, sensor 35 by data transmission interface (such as RS232 interface), and processes, and these data are stored and recorded in data storage recording module 362, and can pass Internet/LAN Connect with the remote data terminal 80 by wire, send relevant information records or give an alarm, etc. These data can also use the signal transmitting module 363 to communicate wirelessly with the remote data terminal 80 through GPRS/GSM/CDMA.

In the present invention, the main body of the sensor 35, the data processing module 36 and the limit switch 31 can be integrated in a box body 32 to form a whole product. The electronic monitoring device has a unique product identification code (ID number ), and stored in the data storage recording module 362, when the signal collected by travel switch 31 and sensor 35, and the alarm signal generated in case of emergency, is transmitted to this device by Internet/LAN (wired) or GPRS/GSM/CDMA (wireless) When the remote data terminal 80 is connected, the identification code of the electronic monitoring box 32 will also be sent to the remote data terminal 80 together. The usage situation of each electronic monitoring device (such as which container is installed on and what is the code of the container) is registered in the database of the remote data terminal 80 . Therefore, the situation of the electronic monitoring device itself can be effectively connected with the sensor monitoring data of the container, so as to realize the global tracking and detection of the tank container.

In the present invention, on the box body 32 corresponding to the position of the sensor 35, a sensing window 33 is provided for the sensor to sense the substances loaded in the tank container 10, such as chemicals, dangerous gases, etc. Substances with characteristics such as explosive, poisonous, harmful, and strong corrosion, that is, the sensor 35 can be a chemical sensor, a gas sensor, or the like. For example, when the gas sensor 35 senses that the sealing surface of the valve 70 and its connecting pipeline leaks, that is, the gas concentration in the valve protection box 20 reaches a certain level, it will send a signal to the corresponding signal acquisition and processing module 361, and then It is forwarded to the remote data terminal 80, so as to realize the monitoring of the leakage situation.

In order to sense leakage better, preferably, the electronic monitoring device 30 is arranged on a side close to the valve element 70 , and the sensing window 33 is opened near the valve element 70 . Moreover, the sensing window 33 can be set as a round hole as shown in FIG. 2a, or as a plurality of small holes as shown in FIG. 1, which can be set correspondingly according to the sensing head of the sensor, and is not limited to the above shapes.

And, in the present invention, a bracket 40 can be set at a predetermined position in the valve protection box 20, for example, the bracket 40 can be set on the side plate 23 near the valve 70 side, or it can be set on the valve protection box 20 On the side plate on one side of the opening, as shown in FIG. 3 c , the electronic monitoring device 30 is fixedly installed on the bracket 40 . In addition, a part or the entire side of the side plate 23 corresponding to the mounting position of the bracket 40 is bent toward the inside of the valve protection box 20 and further extended for a predetermined distance to form a protective reinforcing rib 231 .

As shown in Figure 1, since the bending edge of the protective box 20 can be pried (flat pried) by a crowbar, and then destroyed by an insert piece, therefore, a position corresponding to the travel switch contact 311 on the box cover 21 is also provided with The protection device 50 prevents the contact 311 of the travel switch 31 from being damaged by the insert (that is, using the insert to pretend that the lid is closed). For example, at the position corresponding to the protective reinforcing rib 231, the protective device 50 is arranged as a protective plate structure. Likewise, the protection device 50 can also be a protection ring and other protection structures.

Certainly, the present invention also can have other multiple embodiments, without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes All changes and modifications should belong to the protection scope of the claims of the present invention.
