Description

Technical Field

[0001] This utility model belongs to the field of fuel tank testing technology, specifically referring to a sealing testing device for fuel tanks. Background Technology

[0002] Fuel tank sealing inspection refers to the use of specific technical means to check whether fuel tanks (such as automotive fuel tanks, industrial fuel tanks, and construction machinery fuel tanks) have any leakage points (such as cracks, welding defects, loose joints, etc.) to ensure that they will not leak when storing or transporting fuel (or other liquids), thereby ensuring safety, avoiding waste and environmental pollution.

[0003] In existing technologies, the inspection of fuel tank seals is generally carried out using pressure testing. Inert gas or liquid is introduced into the fuel tank, and the pressure change is used to determine whether the fuel tank is leaking. However, this method has shortcomings: although it can detect the presence of leaks in the fuel tank, it cannot quickly and accurately locate the leak point. It requires careful manual visual inspection to find the leak point, which consumes a lot of time. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, when testing the sealing of an oil tank, leaks cannot be quickly located by visual inspection and require a significant amount of time.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A sealing detection device for an oil tank includes a base, the base being a hollow cavity, an inverted L-shaped bracket fixed to one side of the upper end face of the base, an electric push rod fixed vertically downward to the top wall of the bracket, a pressure plate rotatably mounted on the output end of the electric push rod via a bearing, a vertical plate fixed vertically to the upper end of the base, a leak detection device mounted on the vertical plate, a rotating support device in the base, and an oil tank body placed on the upper end of the rotating support device.

[0006] Furthermore, the leak detection device includes an ultraviolet lamp, which is located inside the upright plate and illuminates the side of the fuel tank body. A camera is installed on the upright plate. Horizontal plates are symmetrically arranged on the upright plate, and an ultraviolet lamp is embedded on the opposite side of the horizontal plates. A camera is also installed on the opposite side of the horizontal plates.

[0007] Furthermore, the rotating support device includes a rotating shaft that rotates in the base via a bearing. A support plate is fixedly connected to the upper end of the rotating shaft, and a second gear is fixedly connected to the lower end of the rotating shaft. A motor is installed inside the base, and the output end of the motor is connected to a first gear and meshes with the second gear.

[0008] Furthermore, a display screen is provided on the upright plate, and the display screen is connected to camera one and camera two via signal.

[0009] Furthermore, the support plate and pressure plate are provided with an anti-slip layer on the contact side with the oil tank body, and the anti-slip layer is made of rubber.

[0010] Furthermore, the telescopic shaft of the electric actuator is coaxial with the rotation shaft.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model uses a leak detection device. The oil tank body is filled with test oil containing fluorescent agent and pressurized by irradiating it with ultraviolet lamp one and ultraviolet lamp two. If the oil tank body leaks, the ultraviolet lamp will emit a fluorescent phenomenon, which can quickly find the leak location.

[0013] 2. This utility model uses a rotating support device to place the oil tank body on a support plate. By pushing the pressure plate down with an electric push rod, the oil tank body can be pressed and fixed. When the oil tank body needs to be rotated, the motor is started, gear one meshes with gear two and rotates, gear two drives the rotating shaft to rotate, so the support plate will drive the oil tank body to rotate synchronously under friction. In this way, the oil tank body will rotate, and ultraviolet lamp one and ultraviolet lamp two can irradiate the surface of the oil tank body to find the leak point. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 This utility model discloses a sealing detection device for an oil tank, comprising a base 1, which is a hollow cavity. An inverted L-shaped bracket 2 is fixedly connected to one side of the upper end of the base 1. An electric push rod 3 is vertically fixed to the top wall of the bracket 2. A pressure plate 4 is rotatably mounted on the output end of the electric push rod 3 via a bearing. A vertical plate 5 is vertically fixed to the upper end of the base 1. A leak detection device 6 is mounted on the vertical plate 5. A rotating support device 7 is provided in the base 1. The oil tank body 8 is placed on the upper end of the rotating support device 7.

[0022] like Figure 1-4 The leak detection device 6 includes an ultraviolet lamp 14, which is located inside the vertical plate 5 and shines on the side of the oil tank body 8. A camera 15 is installed on the vertical plate 5. Horizontal plates 16 are symmetrically arranged on the vertical plate 5. An ultraviolet lamp 17 is embedded on the opposite side of the horizontal plate 16, and a camera 18 is installed on the opposite side of the horizontal plate 16. By adding test oil and fluorescent agent to the oil tank and pressurizing it, if there is a leak in the oil tank, the ultraviolet lamp 14 or ultraviolet lamp 17 can illuminate the fluorescent agent at the leak point, making the leak point quickly found.

[0023] like Figure 1-3The rotating support device 7 includes a rotating shaft 9, which rotates in the base 1 via bearings. A support plate 10 is fixedly connected to the upper end of the rotating shaft 9. An anti-slip layer is provided on the contact side between the support plate 10 and the pressure plate 4 and the oil tank body 8. The anti-slip layer is made of rubber and can increase the friction between the support plate 10 and the oil tank body 8. The telescopic shaft of the electric push rod 3 is coaxial with the rotating shaft 9. A gear 11 is fixedly connected to the lower end of the rotating shaft 9. A motor 12 is installed inside the base 1. The output end of the motor 12 is connected to a gear 13 and meshes with the gear 11. The rotation of the rotating shaft 9 is caused by the meshing of the gear 13 with the gear 11. In this way, the oil tank body 8 on the support plate 10 will rotate, thereby allowing the oil tank body 8 to be fully irradiated by the ultraviolet lamps 14 and 17 to find leaks.

[0024] like Figure 1-3 The upright plate 5 is equipped with a display screen 19, which is connected to the signal of camera 15 and camera 2 18. The display screen 19 can clearly show the situation of ultraviolet light irradiation. If there is fluorescence, it means that the leak is there.

[0025] In practical use, the oil tank body 8 to be tested is placed on the support plate 10, the test oil and fluorescent agent are added to the oil tank body 8, stirred evenly, and the oil tank body 8 is internally pressurized by a pressurizing pump. Then, by starting the electric push rod 3, the pressure plate 4 is pressed and fixed to the upper end of the oil tank body 8.

[0026] By starting the motor 12, gear 13 meshes with gear 2 11 and rotates. Gear 2 11 drives the rotating shaft 9 to rotate. Since the support plate 10 is fixed to the rotating shaft 9, under the action of friction, the support plate 10 will drive the oil tank body 8 to rotate synchronously. The pressure plate 4 will rotate synchronously at the lower end of the electric push rod 3. When the ultraviolet lamp 1 14 and ultraviolet lamp 2 17 are turned on, the surface of the oil tank body 8 will be irradiated. At the same time, the camera 1 15 and camera 2 18 will monitor the irradiation situation in real time and display it on the display screen 19. If there is a leak point on the oil tank body 8, the ultraviolet lamp will irradiate the fluorescent agent and produce a fluorescent phenomenon, so that the leak point can be quickly found.

[0027] When it is necessary to explain, the electrical appliances involved in the solution, such as motor 12 and electric push rod 3, need to be connected to the power supply through cables and centrally controlled by switches. Camera monitoring and imaging are also existing technologies. In practical applications, the principle can be well known to relevant technical personnel, so it will not be described in detail here.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
