Technical Field

[0001] The utility model relates to a protection device, in particular to a ship-used oil spill electrostatic protection device. Background Art

[0002] With the continuous development of my country's economy and the continuous improvement of the legal system, especially since joining the WTO, the country has paid more and more attention to the safety and environmental protection of refined oil storage and transportation. On the one hand, the spillage of oil products creates safety hazards, making the oil products in the surrounding atmosphere and easily burn when encountering open flames, causing fires and causing casualties and other greater accidents; on the other hand, the spillage of oil products causes environmental impacts.

[0003] Oil spills not only pollute the marine environment and are difficult to recover, but also waste manpower and material resources in oil salvage. At the same time, due to manual inspection, oil and gas float in the atmosphere, polluting the atmosphere and causing harm to the physical and mental health of on-site personnel. In recent years, several oil leaks or spills have occurred in my country, causing huge losses to the country and enterprises.

[0004] The petrochemical terminal has time requirements when loading and unloading oil. The loading and unloading time of the smallest tonnage oil tanker is 3-5 hours, and the loading and unloading time of the large tonnage oil tanker is more than 10 hours. In the absence of an electrified overflow prevention device, this is a difficult job for the staff.

[0005] This method of spill prevention, which relies on real-time observation by staff, not only takes up human resources and harms the physical and mental health of on-site personnel, but is also inefficient, slow to unload oil, and cannot completely guarantee that there will be no oil spill accidents, resulting in waste of resources and environmental pollution. The most serious of all is that it poses considerable safety risks.

[0006] Therefore, it is necessary to design a ship oil spill electrostatic protection device. Utility Model Content

[0007] The purpose of the utility model is to overcome the defects in the prior art and provide a ship oil spill electrostatic protection device, which can timely release the static electricity of the ship and monitor the liquid level height when the ship is loading oil in real time, avoid oil spillage, reduce manual labor intensity, and avoid oil spill accidents.

[0009] A preferred technical solution is that it also includes a connecting seat, the liquid level sensor is connected to the connecting seat, the connecting seat is threadedly connected to the oil measuring hole, and a sealing gasket is sandwiched between the connecting seat and the end of the oil measuring hole.

[0010] A preferred technical solution is that the connecting seat is provided with an adjusting component for adjusting the height of the liquid level sensor.

[0011] A preferred technical solution is that the adjustment assembly includes a plurality of telescopic sleeves slidably connected to the connecting seat, the sliding direction of the telescopic sleeves is parallel to the axial direction of the oil measuring hole, the telescopic sleeves include a plurality of telescopic units, two adjacent telescopic units are slidably connected, and a sealing ring is sandwiched between two adjacent telescopic units.

[0012] A preferred technical solution is that the liquid level sensor is slidably connected to the telescopic sleeve, the sliding direction of the liquid level sensor is parallel to the axial direction of the oil measuring hole, and a sealing ring is sandwiched between the liquid level sensor and the telescopic sleeve.

[0013] A preferred technical solution is that the sliding damping between the liquid level sensor and the telescopic sleeve is greater than the sliding damping between two adjacent telescopic units.

[0014] A preferred technical solution is that the end of the telescopic unit is provided with a limiting protrusion that cooperates with the limiting protrusion.

[0015] A preferred technical solution is that the electrostatic clamp is electrically connected to the controller.

[0026] Example

[0027] like Figure 1-5 As shown, the ship-based oil spill electrostatic protection device of the embodiment includes an oil pipeline connected between the cabin and the storage tank, and the oil pipeline is provided with a valve; it also includes an electrostatic clamp 1, one end of which is connected to the ship, and the other end of the electrostatic clamp 1 is grounded; it also includes a controller 4 and a liquid level sensor 2 connected to the controller 4 by an electrical signal, the liquid level sensor 2 is provided with an oil spill probe 21, and the liquid level sensor 2 is detachably arranged in the oil measuring hole 3 of the cabin; the controller 4 is electrically connected to the valve.

[0028] Through such a design, the liquid level sensor 2 detects the oil level height in the cabin. When it reaches the target level, it transmits a signal to the controller 4, and the controller 4 controls the valve to close to avoid oil spill accidents. The liquid level sensor 2 is preferably a piezoelectric liquid level sensor, which has no moving mechanical parts, is shock-proof and drop-resistant, and has no leakage.

[0029] Specifically, it also includes a connecting seat 5, the liquid level sensor 2 is connected to the connecting seat 5, the connecting seat 5 is threadedly connected to the oil measuring hole 3, and a sealing gasket 51 is sandwiched between the connecting seat 5 and the end of the oil measuring hole 3.

[0030] Through such a design, the purpose of detachably fixing the liquid level sensor 2 to the oil measuring hole 3 is achieved.

[0031] Specifically, the connecting seat 5 is provided with an adjusting component for adjusting the height of the liquid level sensor 2 .

[0032] Through such a design, the liquid level height of the liquid level sensor 2 inserted into the oil measuring hole 3 can be adjusted to accurately measure the oil level in the cabin.

[0033] Specifically, the adjustment assembly includes a plurality of telescopic sleeves 6 slidably connected to the connecting seat 5, the sliding direction of the telescopic sleeve 6 is parallel to the axial direction of the oil measuring hole 3, the telescopic sleeve 6 includes a plurality of telescopic units 61, two adjacent telescopic units 61 are slidably connected, and a sealing ring 62 is sandwiched between two adjacent telescopic units 61.

[0034] Such a design not only ensures that the height of the liquid level sensor 2 is adjustable, but also the design of the sealing ring 62 prevents the diffusion of oil and gas, thus ensuring the physical and mental health of the staff.

[0035] Specifically, the liquid level sensor 2 is slidably connected to the telescopic sleeve 6 , the sliding direction of the liquid level sensor 2 is parallel to the axial direction of the oil measuring hole 3 , and a sealing ring 63 is sandwiched between the liquid level sensor 2 and the telescopic sleeve 6 .

[0036] With such a design, the height adjustment range of the liquid level sensor 2 is wider.

[0037] Specifically, the sliding damping between the liquid level sensor 2 and the telescopic sleeve 6 is greater than the sliding damping between two adjacent telescopic units 61 .

[0038] Through such a design, the height of the liquid level sensor 2 can be adjusted preferentially through the adjustment component, thereby reducing the movement and vibration of the liquid level sensor 2 and extending the service life of the liquid level sensor 2.

[0039] Specifically, the end of the telescopic unit 61 is provided with a limiting protrusion 64 that cooperates with the limiting protrusion 64.

[0040] This design prevents the telescopic units 61 from being separated from each other when moving.

[0041] Specifically, the electrostatic clamp 1 is electrically connected to the controller 4 .

[0042] Through such a design, when the resistance value between the oil tanker and the ground exceeds the safe resistance value, a signal can be output to the controller 4 to close the valve to prevent accidents.

[0043] Specifically, the controller 4 is provided with an audible and visual alarm.

[0044] Through such a design, due to the complex on-site working environment, which is an open riverside with large space and high noise, the sound and light alarm can easily attract the attention of on-site operators.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
