Embodiment Construction

[0024] The present invention is described in detail below by means of examples, but the following examples are only illustrative, and the protection scope of the present invention is not limited by these examples.

[0025] like figure 1 As shown, the storage tank floor detection device of the present invention includes a drag cable 1 , a sealed circuit box 2 , a driven wheel group 3 , a permanent magnetic adsorption group 4 , a detection probe seat 5 , a steering mechanism 6 and a driving mechanism 7 .

[0026] like figure 1 As shown, the towed cable 1 and the sealed line box 2 of the storage tank floor detection device of the present invention are glued together by a sealant to ensure sealing performance and sufficient mechanical strength. The tow cable provides power supply and control signals for the detection device of the storage tank floor of the present invention, and provides safety assistance. When the detection device encounters obstacles in the working environment...

Abstract

The invention discloses a detecting device of storage tank soleplate, which comprises a permanent magnetic adsorption mechanism comprising an armature and two permanent magnet groups respectively arranged on one end of the armature and adsorbed on a storage tank soleplate to be detected, and the permanent magnet groups are wrapped by a sealing cover; a detecting probe seat arranged on the armature between the two permanent magnet groups of the permanent magnetic adsorption mechanism for mounting a probe and a detecting soleplate, and the detecting probe seat is provided with a sealing structure for providing sealing protection to a probe circuit; a steering mechanism connected with one end of the permanent magnetic adsorption mechanism, and a movable sealing element is installed thereon for steering the detecting device; a driving mechanism connected with the steering mechanism for driving the detecting device to move; a driven wheel set arranged on the other end of the permanent magnetic adsorption mechanism, and the driven wheel set is driven by the driving mechanism to move with the detecting device. The device of the invention has static and movable sealing structures, and the device can be used for detecting the defects of oil storage tank soleplates by carrying different categories of sensors so as to avoid the defects of the common detecting methods.

Description

Technical field: [0001] The invention relates to a detection device, in particular to a storage tank bottom plate detection device, which belongs to the field of automatic detection devices. Background technique: [0002] As a kind of static equipment for storage medium in petroleum and chemical industry, storage tank is widely used. Because the bottom plate of the storage tank is in direct contact with the foundation, the corrosion is more serious than other parts. Therefore, it is of great significance to detect the bottom plate of the storage tank. [0003] At present, the detection method of stopping production and opening the tank is generally used for the bottom plate of the storage tank. First empty the medium in the tank, and then use non-destructive testing methods such as magnetic flux leakage, ultrasonic wave, and magnetic particle for testing. In order to improve the detection efficiency, ZL200920100319.6 discloses a detection device that uses a motor to provid...
