Description

Technical Field

[0001] This utility model relates to the field of fuel tank technology, specifically to a main fuel tank fuel level alarm device. Background Technology

[0002] The main oil tank level alarm is a key safety device in industrial equipment (such as generator sets, hydraulic systems, internal combustion engines, etc.) used to monitor the oil level in the tank in real time and trigger an early warning. However, how to avoid errors in oil level detection and how to prevent oil leakage at high levels are urgent problems to be solved.

[0003] CN218673799U discloses a hydrostatic oil tank level alarm device, relating to the field of hydrostatic oil tank technology. This utility model includes an oil tank and a tank cover. The tank cover is fitted onto the top of the oil tank. A visual level monitoring mechanism for observing the internal liquid level is provided on the surface of the oil tank. A level alarm device for monitoring the liquid level is provided on the top inner side of the oil tank and the top of the tank cover. This utility model uses a float to float on the surface of the lubricating oil inside the tank due to the buoyancy of the lubricating oil. When the liquid level of the lubricating oil rises or falls, the float moves vertically under the restriction of a limit rod. When the liquid level is too high, the float's contact rod contacts a contact switch, triggering an audible and visual alarm. The triggering of the contact switch, through a controller, stops the oil pump to prevent oil overflow.

[0004] The aforementioned hydrostatic oil tank level alarm device guides the float only through a single limiting rod. When the oil level fluctuates, the float is prone to lateral displacement or jamming, affecting the alignment accuracy of the contact rod and the contact switch, which may cause false alarms or missed alarms. At the same time, when the oil level is high, there is no active sealing mechanism between the float and the tank cover after it rises, and the oil may seep out through the gap of the limiting rod, posing a risk of leakage.

[0008] Preferably, the cover plate assembly further includes an iron sheet ring, which is fixedly connected to the bottom of the cover plate body, and the cover plate assembly further includes a slot, which is formed at the bottom of the cover plate body located inside and outside the iron sheet ring.

[0009] Preferably, the oil level monitoring component further includes a float, which is fixedly connected to the outside of the lower tray.

[0010] Preferably, the oil level monitoring component further includes a magnetic suction plate, which is fixedly connected to the top of the lower tray and corresponds to the position of the iron plate ring. The oil level monitoring component also includes a sealing ring, which is fixedly connected to the top of the lower tray and located inside and outside the magnetic suction plate, and corresponds to the position of the slot.

[0011] Preferably, the oil level monitoring component further includes a cross groove, which is formed through the middle of the lower tray. The lower tray is slidably connected to the cross post through the cross groove. A connecting rod is also fixedly connected to the top of the lower tray, and the connecting rod corresponds to the position of the groove.

[0012] Preferably, the oil level monitoring component further includes an upper tray, which is located on the outside of the oil tank body.

[0014] The present invention adopts the above technical solution and has the following beneficial effects compared with the prior art: This design uses a cross-shaped column and a cross-shaped groove to restrict the lower tray in four directions, completely avoiding lateral displacement. At the same time, a floating pad is used to increase buoyancy stability and further reduce oil fluctuation interference. This design adopts a magnetic dynamic sealing design. When the oil level reaches the warning value, the magnetic plate attracts the iron ring, and the sealing ring is pressed into the groove to form a double sealing barrier. This design can prevent the groove from being completely sealed by the sealing ring and prevent oil leakage. Attached Figure Description

[0019] The cover plate assembly 2 also includes a through groove 211, which is a ring-shaped through groove that runs through the entire body of the cover plate 21.

[0020] The cover plate assembly 2 also includes an iron sheet ring 23, which is fixedly connected to the bottom of the cover plate body 21. The cover plate assembly 2 also includes a slot 231, which is opened at the bottom of the cover plate body 21 and located inside and outside the iron sheet ring 23.

[0021] The oil level monitoring component 3 also includes a float 332, which is fixedly connected to the outside of the lower tray 33.

[0022] The oil level monitoring component 3 also includes a magnetic suction plate 34, which is fixedly connected to the top of the lower tray 33. The magnetic suction plate 34 corresponds to the position of the iron ring 23. The oil level monitoring component 3 also includes a sealing ring 341, which is fixedly connected to the top of the lower tray 33 and located inside and outside the magnetic suction plate 34. The sealing ring 341 corresponds to the position of the slot 231.

[0023] The oil level monitoring component 3 also includes a cross groove 331, which is opened through the middle of the lower tray 33. The lower tray 33 is slidably connected to the cross post 22 through the cross groove 331. A connecting rod 32 is also fixedly connected to the top of the lower tray 33, and the position of the connecting rod 32 corresponds to the through groove 211.

[0024] The oil level monitoring component 3 also includes an upper tray 31, which is located on the outside of the oil tank body 1. A ball bearing 312 is rotatably connected to the side of the upper tray 31, and the ball bearing 312 contacts the side of the oil tank body 1.

[0026] The working principle and usage process of this utility model are as follows: When the oil level inside the oil tank body 1 rises, the lower tray 33 located outside the cross column 22 can rise along with the oil level in conjunction with the float 332. When the current tray 33 rises to the oil level warning value, the cross groove 331 will contact the alarm button 421, which will then trigger an alarm through the control panel 41. In particular, this design features a cross groove 331 in the middle of the lower tray 33, which, together with the cross post 22, keeps the lower tray 33 in a horizontal position, thereby preventing the trigger plate 311 from accidentally touching the alarm button 421 due to oil displacement. Specifically, when the trigger plate 311 reaches the height of the alarm button 421, the magnetic plate 34 located on the top of the lower tray 33 will be attracted to the iron ring 23. At this time, the sealing ring 341 on the top of the lower tray 33 will contact and press against the slot 231. This design allows the lower tray 33 to cooperate with the magnetic plate 34 to form a sealed closure of the through groove 211, thereby preventing oil from seeping out from the through groove 211 when the oil level is high.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
