Description

Technical Field

[0001] This utility model relates to the field of fuel transportation, and in particular to a fuel leak collection tank. Background Technology

[0002] In the field of fuel transportation, fuel leakage at pipe joints is a long-standing and urgent problem. Traditional fuel transportation systems typically rely on simple threaded connections between pipes. This method often fails to guarantee a proper seal in complex working environments, such as those with vibration, temperature variations, and pressure fluctuations. Once a pipe joint leaks, fuel will directly spill into the surrounding environment. On the one hand, this causes serious environmental pollution, as harmful substances in the fuel pollute soil and water bodies, disrupting the ecological balance. On the other hand, leaked fuel also poses a significant safety hazard; exposure to open flames or high temperatures could trigger fires or even explosions, threatening lives and property.

[0003] Therefore, it is necessary to provide a new fuel leak collection tank to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fuel leak collection tank that can collect oil leaking from oil pipe joints, avoid oil leak pollution, and has high safety.

[0005] The fuel leak collection tank provided by this utility model includes two oil pipes connected by a threaded joint and an oil receiving cylinder sleeved on the threaded joint. Both ends of the oil receiving cylinder are equipped with external threaded rings, and the external threaded rings are fixedly connected to the oil receiving cylinder by a number of connecting blocks distributed around the oil pipes. An expandable and contractible annular sealing airbag is fixedly installed between the external threaded rings and the oil receiving cylinder, and the annular sealing airbag is in close contact with the outer wall of the threaded joint ring. An internal threaded ring that compresses the annular sealing airbag is threadedly connected to the external threaded ring.

[0006] The oil receiving cylinder is equipped with a detachable collection tank, and the collection tank is equipped with an exhaust mechanism.

[0007] Preferably, a conical cylinder sleeved on the oil receiving cylinder is fixedly installed at one end of each of the two internally threaded rings facing each other, and the conical cylinder abuts against the inclined ring wall of the oil receiving cylinder.

[0008] Preferably, the collection tank is connected to an internally threaded connector via a hose, and an externally threaded connecting pipe that is threadedly connected to the internally threaded connector is fixedly installed on the oil receiving cylinder.

[0009] Preferably, the external threaded connecting pipe is fixedly installed on the outer ring wall of the center of the oil receiving cylinder and is set vertically downward.

[0010] Preferably, the exhaust mechanism includes a vertical pipe, which is vertically fixedly installed on the collection tank and communicates with its interior. The vertical pipe has a tapered cross-section at both its upper and lower ends, and a float ball with clearance fit is installed in the vertical pipe.

[0011] Preferably, a pressure alarm is installed on the oil receiving cylinder.

[0012] Preferably, both external threaded rings are provided with internal threaded holes, and a locking bolt is inserted into the internal threaded hole for threaded connection with it. The external threaded rings are fixedly connected to the threaded connector by the locking bolt.

[0013] Preferably, a damping rubber pad is fixedly installed at the end of the locking bolt that abuts against the threaded connector.

[0014] Compared with related technologies, the fuel leak collection tank provided by this utility model has the following advantages:

[0015] 1. This utility model, through the design of annular sealing airbag and internal threaded ring, can tightly wrap the connection of threaded joint. When the internal threaded ring squeezes the annular sealing airbag, the airbag expands and fits tightly against the outer wall of the threaded joint, forming a sealed cavity, which effectively prevents fuel from leaking from the joint to the external environment, greatly reducing the risk of environmental pollution and safety accidents.

[0016] 2. The oil receiving cylinder in this utility model is equipped with a detachable collection tank, which facilitates the centralized collection of leaked fuel.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 This utility model provides a fuel leak collection tank, which includes: two oil pipes 1 connected by a threaded connector 11 and an oil receiving cylinder 2 sleeved on the threaded connector 11. Both ends of the oil receiving cylinder 2 are equipped with external threaded rings 3, and the external threaded rings 3 are fixedly connected to the oil receiving cylinder 2 by a plurality of connecting blocks 31 distributed around the oil pipes 1. An expandable and contractible annular sealing airbag 5 is fixedly installed between the external threaded rings 3 and the oil receiving cylinder 2, and the annular sealing airbag 5 is tightly attached to the outer wall of the threaded connector 11. An internal threaded ring 4 that compresses the annular sealing airbag 5 is threadedly connected to the external threaded rings 3. A detachable collection tank 6 is installed on the oil receiving cylinder 2, and an exhaust mechanism 7 is installed on the collection tank 6.

[0027] It should be noted that the oil receiving cylinder 2 in this utility model is mainly for collecting and receiving oil leaking from the joint of the oil pipe 1. It needs to be pre-installed before the two oil pipes 1 are connected. Specifically, before the two oil pipes 1 are connected, the oil receiving cylinder 2 is passed through one of the oil pipes 1 from its end. The two oil pipes 1 are then connected and fixed using a threaded connector 11. The oil receiving cylinder 2 is moved so that the connection part of the threaded connector 11 is located in the middle of the oil receiving cylinder 2. By rotating the inner threaded ring 4, it moves on the outer threaded ring 3, thereby compressing the outer part of the annular sealing airbag 5. This causes the inner part of the annular sealing airbag 5 to expand until it tightly adheres to the outer ring wall of the threaded connector 11. The oil receiving cylinder 2 and the expanded annular sealing airbag 5 form a... The sealing cavity encloses the threaded joint 11 to prevent oil leakage from the threaded joint 11, thus avoiding oil leakage into the external environment and reducing the risk of pollution. When oil leakage begins at the threaded joint 11 of the two oil pipes 1, the sealing cavity formed by the oil receiving cylinder 2 and the expanding annular sealing airbag 5 will receive the oil and collect it through the collection tank 6, facilitating centralized treatment of leaked oil, avoiding oil waste, and preventing safety hazards caused by oil contact with high temperature or open flame. The venting mechanism 7 enables the venting of the collection tank 6 to ensure the internal pressure balance of the collection tank 6, preventing the collection effect of oil from being affected by excessive internal pressure or causing the sealing structure to fail, thus ensuring the normal operation of the collection tank 6.

[0028] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 Two internal threaded rings 4 are each fixedly installed with a cone 41 sleeved on the oil receiving cylinder 2 at one end of their opposite sides, and the cone 41 abuts against the inclined ring wall of the oil receiving cylinder 2.

[0029] It should be noted that the uncompressed annular sealing airbag 5 is located between the external threaded ring 3 and the oil receiving cylinder 2. The outer part (located outside the external threaded ring 3) and the inner part (located inside the external threaded ring 3) of the annular sealing airbag 5 are aligned. When the internal threaded ring 4 is rotated, the cone 41 first contacts the outer part of the annular sealing airbag 5, gradually squeezing and compressing the outer part of the annular sealing airbag 5, thereby causing the inner part of the annular sealing airbag 5 to expand until it is tightly attached to the outer ring wall of the threaded joint 11. Through the contact and compression between the cone 41 and the annular sealing airbag 5, the degree of expansion of the annular sealing airbag 5 can be more precisely controlled.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The collection tank 6 is connected to an internal threaded connector 62 via a hose 61, and an external threaded connector 21 that is threadedly connected to the internal threaded connector 62 is fixedly installed on the oil receiving cylinder 2; that is, the internal threaded connector 62 is threadedly connected to the external threaded connector 21, and the two can be easily and quickly connected and separated, so that the collection tank 6 can be separated from the oil receiving cylinder 2; the design that the collection tank 6 can be separated from the oil receiving cylinder 2 allows the collection tank 6 to be quickly replaced after the oil is full, so that the device can perform continuous oil collection under certain conditions.

[0031] The threaded connecting pipe 21 is fixedly installed on the outer annular wall of the oil receiving cylinder 2 and is vertically downward. Due to gravity, the oil leaking from the threaded joint 11 will flow downward along the inner wall of the oil receiving cylinder 2. Placing the threaded connecting pipe 21 on the outer annular wall of the oil receiving cylinder 2 and vertically downward allows the oil to flow directly to the collection tank 6, preventing the oil from accumulating in the oil receiving cylinder 2 or flowing to other unnecessary places, thus improving the efficiency and accuracy of oil collection.

[0032] In the embodiments of this utility model, please refer to Figure 1 , Figure 4 and Figure 5 The exhaust mechanism 7 includes a vertical pipe 71, which is vertically fixed on the collection tank 6 and communicates with its interior. The upper and lower ends of the vertical pipe 71 are both tapered, and a float 72 with clearance fit is installed in the vertical pipe 71.

[0033] It should be noted that: under the action of gravity, the float 72 is located at the lower end of the vertical pipe 71. The inside of the collection tank 6 is connected to the outside atmosphere through the openings at both ends of the vertical pipe 71, allowing air to escape from the tank to balance the pressure and allow the oil to flow in smoothly. As the oil continues to flow in, the oil level rises, and the buoyancy of the float 72 gradually increases. When the buoyancy exceeds the weight of the float, the float 72 rises along the vertical pipe 71. When the float 72 rises to the upper opening of the vertical pipe 71, because the upper and lower ends of the vertical pipe 71 are conical, the float 72 can fit tightly against the conical opening, thereby blocking the opening, preventing air from entering and oil from overflowing, and achieving a seal.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 A pressure alarm 22 is installed on the oil receiving cylinder 2;

[0035] It should be noted that when the collection tank 6 is full of oil and the float 72 blocks the upper opening of the vertical pipe 71, the entire device is in a sealed state. The oil that continues to leak from the threaded joint 11 will gradually increase the pressure inside the device. When the pressure reaches a certain level, the pressure alarm 22 will be triggered to remind that the device is full of oil and needs to be dealt with in time.

[0036] The pressure alarm 22 is model number HJ16G.

[0037] Please see Figure 6 Another fuel leak collection tank provided in this utility model embodiment has two external threaded rings 3, each with an internal threaded hole 32, and a locking bolt 8 threadedly connected to the internal threaded hole 32 is inserted therein. The external threaded rings 3 are fixedly connected to the threaded connector 11 by the locking bolt 8.

[0038] It should be noted that after the device is installed, the locking bolt 8 can be screwed into the internal threaded hole 32, so that the end of the locking bolt 8 abuts against the outer wall of the threaded connector 11, thereby limiting the external threaded ring 3. The locking bolt 8 is threadedly connected to the internal threaded hole 32, which can generate a large axial force, tightly fixing the external threaded ring 3 to the threaded connector 11, effectively preventing the external threaded ring 3 from loosening due to vibration, pressure and other factors during operation, and ensuring the tightness and stability of the connection.

[0039] The locking bolt 8 is fixedly fitted with a damping rubber pad at the end that abuts against the threaded connector 11. The rubber pad is soft and can prevent the end of the locking bolt 8 from scratching or damaging the surface of the threaded connector 11, thus protecting the surface quality of the threaded connector.

[0040] The working principle of the fuel leak collection tank provided by this utility model is as follows:

[0041] The oil receiving cylinder 2 in this invention is mainly for collecting and receiving oil leaking from the joint of the oil pipe 1. It needs to be pre-installed before the two oil pipes 1 are connected. Specifically, before the two oil pipes 1 are connected, the oil receiving cylinder 2 is passed through one of the oil pipes 1 from its end. The two oil pipes 1 are then connected and fixed using a threaded connector 11. The oil receiving cylinder 2 is moved so that the connection part of the threaded connector 11 is located in the middle of the oil receiving cylinder 2. When the internal threaded ring 4 is rotated, the cone 41 first contacts the outer part of the annular sealing airbag 5, gradually squeezing and compressing the outer part of the annular sealing airbag 5, thereby sealing the annular airbag. The inner part of the bladder 5 begins to expand until it tightly adheres to the outer annular wall of the threaded joint 11. The oil receiving cylinder 2 and the expanded annular sealing bladder 5 form a sealed cavity that encloses the connection of the threaded joint 11, preventing oil leakage from the threaded joint 11 and avoiding oil leakage into the external environment, thus reducing the risk of pollution. When oil begins to leak at the threaded joint 11 of the two oil pipes 1, the sealed cavity formed by the oil receiving cylinder 2 and the expanded annular sealing bladder 5 will receive the oil. The oil flows through the hose 61 into the collection tank 6 for collection, facilitating centralized treatment of the leaked oil and avoiding oil waste. This design avoids safety hazards caused by oil coming into contact with high temperatures or open flames. The venting mechanism 7 vents the collection tank 6. The float 72, under gravity, is positioned at the lower end of the vertical pipe 71. The collection tank 6 is connected to the outside atmosphere through the openings at both ends of the vertical pipe 71, allowing air to escape and balancing the pressure. This ensures smooth oil flow and maintains internal pressure balance, preventing excessive internal pressure from affecting oil collection or causing sealing failure, thus guaranteeing the normal operation of the collection tank 6. As oil continuously flows in and the oil level rises, the buoyancy of the float 72 gradually increases. When the buoyancy exceeds a certain value... When the float is under gravity, the float 72 rises in the vertical tube 71. When the float 72 rises to the opening at the top of the vertical tube 71, the float 72 can fit tightly with the conical opening at both ends of the vertical tube 71, thus blocking the opening and preventing air from entering and oil from overflowing, achieving a seal. When the collection tank 6 is full of oil and the float 72 blocks the opening at the top of the vertical tube 71, the entire device is in a sealed state. The oil that continues to leak at the threaded joint 11 will gradually increase the pressure inside the device. When the pressure reaches a certain level, the pressure alarm 22 will be triggered to remind that the device is full of oil and needs to be dealt with in time.

[0042] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
