AI Technical Summary
During the process of oil extraction and utilization, it is difficult for the existing technology to effectively warn and prevent overflow problems caused by excessive liquid level of elevated oil tanks, especially when the oil volume inside the oil tank is large, there is a lack of an efficient early warning mechanism.
An overhead oil tank liquid level alarm device is designed, including a tank body, an early warning mechanism and a backup fuel tank. The early warning mechanism consists of an extrusion rod, a load-bearing spring, an early warning sign and a floating plate. When the liquid level is too high, the floating plate drives the extrusion rod to move the early warning sign upwards, and a part of the crude oil flows into the spare oil tank through the communication pipe to prevent overflow.
An efficient early warning of the liquid level of the elevated oil tank is achieved to prevent overflow, and through the design of a backup oil tank, the amount of crude oil inside the oil tank is effectively managed to avoid overflow accidents.

[0002] In the process of oil extraction and utilization, oil tanks are needed to store oil or other oil products, and can be set up not only in refineries but also in oil fields. During use, an oil tank area consisting of multiple oil tanks is often formed.
[0003] After the oil field is mined, it needs to be temporarily stored in oil tanks for transportation. When the existing oil tanks are filled with oil, the staff needs to observe the oil level inside the tank and then issue an early warning to prevent overflow, which is inconvenient. In addition, an early warning can only be issued when the internal oil level is generally large, which makes it easy for the internal oil to overflow. In view of this, we proposed an elevated oil tank liquid level over-high alarm device. Summary of the invention
[0004] The utility model aims to provide an over-high liquid level alarm device for an elevated oil tank to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION
[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an elevated oil tank liquid level over-high alarm device, comprising a tank body 1, an oil filling port 2 is arranged on the tank body 1, crude oil is injected into the interior of the tank body 1 through the oil filling port 2, an oil outlet 3 is arranged on the side wall of the tank body 1, a mounting plate 4 is fixedly installed on the side wall of the tank body 1, a spare oil tank 5 is fixedly installed on the mounting plate 4, the spare oil tank 5 is connected to the tank body 1 through a connecting pipe 6, and an early warning mechanism 7 is arranged inside the tank body 1.
[0023] In this embodiment, an early warning mechanism 7 is provided inside the tank body 1. The early warning mark 73 can be driven upward by the squeezing rod 71 in the early warning mechanism 7 to give an early warning. The end of the connecting pipe 6 is opened upward by the baffle 715, so that a part of the crude oil inside the tank body 1 can flow to the inside of the spare oil tank 5 to prevent the tank body 1 from being overfilled with crude oil. At the same time, after the floating plate 75 is slightly lowered in height, the limiting rod 712 is still clamped in the inside of the clamping groove 713, which can prevent the squeezing rod 71 from driving the early warning mark 73 to descend, resulting in a secondary oil filling situation.
[0024] The above-mentioned warning mechanism 7 includes an extrusion rod 71, which passes through the interior of the tank body 1. The outer wall of the extrusion rod 71 is fixedly connected to one end of a load-bearing spring 72, and the other end of the load-bearing spring 72 is fixedly connected to the outer wall of the tank body 1. Then, the elastic force of the load-bearing spring 72 causes the extrusion rod 71 to drive the warning mark 73 to move downward to reset, so as to facilitate the warning work again. The end of the extrusion rod 71 is fixedly installed with a warning mark 73, which can be driven by the extrusion rod 71 to move upward for warning. A slide groove 7 is provided on the inner wall of the tank body 1 4. A floating plate 75 is slidably connected to the inner wall of the chute 74. As the crude oil volume inside the tank body 1 gradually increases, the crude oil can drive the floating plate 75 to move upward to squeeze the end of the squeezing rod 71. A vertical rod 77 runs through the inside of the floating plate 75. The vertical rod 77 runs through the inside of the floating plate 75. A disc 76 is fixedly installed at the end of the vertical rod 77. The disc 76 is located at the bottom of the floating plate 75. The floating plate 75 continuously descends to drive the vertical rod 77 above the disc 76 to move downward to pull the end of the support rod 79. A bent plate 78 is fixedly installed on the inner wall of the tank body 1. The outer wall of the bent plate 78 is slidably connected with a hinge block 710, which is hinged to one end of the support rod 79, and the other end of the support rod 79 is hinged to the end of the vertical rod 77. The outer wall of the hinge block 710 is fixedly connected to one end of a compression spring 711, and the other end of the compression spring 711 is fixedly connected to the outer wall of the bent plate 78. The compression spring 711 is in a compressed state, and the elastic force of the compression spring 711 causes the hinge block 710 to drive the limit rod 712 to move rightward and be clamped in the inside of the clamping groove 713, so that the position of the warning mark 73 can be clamped and stabilized. A warning is given regularly, a limit rod 712 is fixedly installed on the side wall of the hinge block 710, a slot 713 is opened on the extrusion rod 71, the slot 713 is located on the side of the limit rod 712, the outer wall of the extrusion rod 71 is fixedly connected to one end of the connecting rod 714, and a baffle 715 is fixedly installed on the other end of the connecting rod 714. The extrusion rod 71 rises and drives the baffle 715 at the end of the connecting rod 714 to move upward to open the end of the connecting pipe 6, so that part of the crude oil can flow to the inside of the spare oil tank 5, so that the crude oil inside the tank body 1 is not easy to overflow.
[0025] When the oil level rises, the oil level rises to a certain level, and ... A portion of the crude oil inside flows to the inside of the spare oil tank 5, making it difficult for the crude oil inside the tank body 1 to overflow, and then the height of the crude oil inside the tank body 1 drops, causing the float plate 75 to drop, but the limit rod 712 is still clamped in the inside of the slot 713, so that the warning mark 73 is still in the warning state. When the crude oil inside the tank body 1 is discharged through the oil outlet 3, the float plate 75 continues to drop and drives the disc 76 to move downward, and finally the disc 76 drives the vertical rod 77 to move downward to pull the end of the support rod 79, and through the hinge between the support rod 79 and the hinge block 710, the hinge block 710 drives the limit rod 712 to move to the left out of the slot 713, and then the elastic force of the load-bearing spring 72 is used to make the extrusion rod 71 drive the warning mark 73 to move downward to reset, so as to facilitate the warning work again.
[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
