Description

TECHNICAL FIELD

[0001] The utility model belongs to valve box electronic lead seal technical field, more specifically, relate to a kind of oil tank truck lead seal equipment. BACKGROUND

[0002] Oil tank truck appears difficult to manage in the process of transportation due to the restriction of region and manpower. The real-time operation of each vehicle cannot be monitored, and the existing electronic lead seal device has structural limitations, which leads to the vulnerability of valve box locking. The user can easily simulate the closing of the valve, which causes the false appearance that the electronic lock is sealed but the valve is not actually closed. Although the electronic seal is used, the oil leakage phenomenon still occurs, which causes great economic loss.

[0003] For example, the valve box electronic lead seal device of patent application No. CN201620351347.5 includes an electronic pneumatic lock and a flip cover that controls the opening and closing of the box door. The electronic pneumatic lock is installed on the valve box, and the electronic pneumatic lock has a pressure rod. The front end of the box on one side of the electronic pneumatic lock is provided with a flip cover. The electronic pneumatic lock controls the rotation of the pressure rod to open and close the flip cover, complete the sealing and unsealing of the box door. Once the box door is opened, the flip cover cannot be buckled, and the electronic pneumatic lock pressure rod cannot be returned. The sensor of the electronic pneumatic lock notifies the terminal controller, effectively avoids the simulated closing of the valve, improves the electronic seal management system, accurately locates the vehicle and lead seal signal, reduces the investment of manpower and material resources, and more effectively prevents the oil leakage phenomenon.

[0004] Although the above-mentioned valve box electronic lead seal device reduces the investment of manpower and material resources, the lead seal effect is poor. INVENTION CONTENTS
