Description

Technical Field

[0001] The utility model relates to the field of storage tank detection devices, in particular to a detection device for atmospheric pressure storage tanks of combustible liquids. Background Art

[0002] An atmospheric pressure storage tank refers to a steel welded storage tank with a design pressure less than 0.1 MPa, built on the ground, and storing non-artificially refrigerated and non-highly toxic liquid media such as petroleum and chemical substances. Storage tanks are widely used storage equipment in petrochemical production, and are used in the refining industry to store various raw oils, semi-finished oils, refined oils, aromatic products, liquefied gas, etc.

[0003] Chinese Patent No. CN214310186U discloses "A Detection Device for Atmospheric Pressure Storage Tanks of Combustible Liquids". Through the setting of clamping springs, etc., two rubber clamping blocks clamp the liquid injection pipe, thus avoiding displacement during subsequent detection and causing unstable detection. The extension rod and other detection mechanisms extend from the liquid injection pipe into the storage tank to be detected. By slowly extending the control rod downward, under the action of the pulley, the position of the extension rod in the tank changes, indirectly driving the mounting plate to move to one side. Through the setting of the lighting lamp and the camera, the transmission antenna transmits the internal image of the tank to the display in the user's hand, thus realizing intelligent detection, making the detection process not require personnel to enter the tank, and improving the safety of the entire detection process;

[0004] Although the above-mentioned detection device for atmospheric pressure storage tanks of combustible liquids has certain advantages in the ability of storage tank detection, each detection requires manual operation by staff, and the safety detection ability of the storage tank is not perfect enough, and it cannot detect the breakage and leakage of the storage tank, which has certain risks.

The upper end surface of the first outer shell 21 is finally attached to the storage tank body 1, and the lower side of the first outer shell 21 is in a funnel shape, facilitating the flow of liquid towards the liquid sensor 24.

[0023] Please refer to Figure 4 , the present utility model provides a detection device for a combustible liquid atmospheric storage tank. The driving structure 5 includes a second outer shell 51, a motor 52, a rotating shaft 53, a first bevel gear 54, a second bevel gear 55 and a lifting structure 56. A motor 52 is installed on the right side of the inner wall of the second outer shell 51. The output end of the motor 52 is in transmission connection with the rotating shaft 53. A first bevel gear 54 is sleeved on the left side of the rotating shaft 53. The first bevel gear 54 is meshed with the second bevel gear 55. The lower side of the second bevel gear 55 penetrates through the second outer shell 51 and is connected to the lifting structure 56. The second outer shell 51 is installed on the upper end surface of the storage tank body 1.

[0024] Please refer to Figure 5, the present utility model provides a detection device for a combustible liquid atmospheric storage tank. The lifting structure 56 includes an annular plate 561, a scanner 562, a screw rod 563, and a limiting rod 564. The left side of the inner wall of the annular plate 561 is equipped with a scanner 562. The left and right sides of the annular plate 561 are respectively penetrated by the screw rod 563 and the limiting rod 564. The lower end of the screw rod 563 is rotationally connected to a bearing, and the lower end surfaces of the bearing and the limiting rod 564 are fixedly connected to the first outer shell 21.

[0025] The working principle is as follows:

[0026] First, first place the new device in the required position and conduct circuit connection;

[0027] Second, when the storage tank body 1 is damaged and leaks, the leaked liquid flows downward through the liquid leakage groove 22 into the interior of the first outer shell 21. Since the lower side of the first outer shell 21 is funnel-shaped, the liquid flows to the liquid sensor 24. The liquid sensor 24 feeds back to the external controller to control the alarm 4 to give an alarm, warning the staff;

[0028] Third, at the same time, the liquid sensor 24 feeds back to the external controller to control the motor 52 to operate. The output end of the motor 52 drives the rotating shaft 53 to rotate. The rotating shaft 53 drives the first bevel gear 54 to rotate. Since the first bevel gear 54 is meshed with the second bevel gear 55, the first bevel gear 54 drives the screw rod 563 to rotate through the second bevel gear 55. The screw rod 563 utilizes the threaded connection with the inner wall of the annular plate 561, so that the screw rod 563 drives the annular plate 561 to move downward in cooperation with the limiting rod 564. The annular plate 561 drives the four groups of scanners 562 to move downward. The four groups of scanners 562 comprehensively scan the storage tank body 1. The scanners 562 feed back the scanned damaged data to the background, achieving the effect of quickly detecting the damaged and leaked position of the storage tank body 1. And in cooperation with the warning of the alarm 4, it can remind the staff to process the storage tank body 1 as soon as possible to avoid causing harm.
