Description

Technical Field

[0001] This utility model relates to the field of oil storage tank detection technology, specifically an oil storage tank leak detection device. Background Technology

[0002] Oil storage tanks are containers used to store liquid petroleum and petroleum products, and are widely used in many fields such as petroleum, chemical, transportation, and agriculture.

[0003] Existing oil storage tanks require leak testing after production. For small oil storage tanks, existing leak detection devices are often simple water tanks. The tank opening is connected to an air supply pipe, the tank is submerged, and air is continuously supplied to observe for bubbles, thus detecting leaks. However, in practice, workers manually place the tank into the water tank and remove it after testing, which is cumbersome and prone to dripping. Therefore, we propose a new leak detection device for oil storage tanks. Utility Model Content

[0004] The purpose of this invention is to provide a leak detection device for oil storage tanks, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak detection device for an oil storage tank, comprising a base, wherein a water tank is fixedly installed on one side of the top of the base, and further comprising:

[0006] A servo motor is fixedly installed on one side of the top of the base. A turntable is fixedly connected to the outer end of the drive shaft of the servo motor. A rotating plate is fixedly connected to the top of the turntable. A strip groove is opened on one side wall of the rotating plate, and a lifting component is installed in the strip groove.

[0007] A horizontal plate is connected to a lifting assembly. An adjusting plate is connected to the bottom of the horizontal plate, and side plates are connected to both sides of the bottom of the adjusting plate. Hollow clamps are rotatably installed on the inner wall of the side plates. A connecting nozzle is fixedly connected to one side wall of one of the clamps, and a rotary joint is connected to the back of the clamp corresponding to the connecting nozzle. The rotary joint passes through the side plate and is connected to an air source pipe. A waterproof motor is fixed to the outer wall of the other side plate, and the drive shaft of the waterproof motor passes through the side plate and is fixedly connected to the clamp.

[0008] By adopting the above technical solution, the lifting assembly first lowers the horizontal plate, causing the side plates on both sides to descend. The oil tank is then placed between two clamping plates, aligning the oil inlet at the end of the tank with the connecting nozzle. An adjusting plate then moves the side plates towards the center, clamping the oil pipe with the clamping plates and inserting the connecting nozzle into the inlet, sealing it. The lifting assembly then raises the oil tank, and a servo motor rotates the rotating plate, bringing the oil tank to the top of the water tank. The lifting assembly then lowers the oil tank, submerging it in the water. Gas is introduced into the rotary joint via a gas supply pipe, flowing through the clamping plate cavities into the connecting nozzle and then into the oil tank. When the oil tank leaks, bubbles appear in the water tank. A waterproof motor rotates the oil tank, allowing any leaks on the lower surface to be observed from the upper surface, making it easier to see the bubbles in the water. This avoids situations where leaks are not visible and replaces manual loading and unloading, improving operational convenience and reducing the workload of workers.

[0009] In a preferred embodiment of this utility model, the lifting assembly includes:

[0010] A lead screw motor is fixedly installed at the bottom of the inner cavity of the strip groove. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The top of the lead screw is rotatably connected to the inner wall of the strip groove. A matching lead screw slider is fitted on the outer wall of the lead screw. The outer wall of the lead screw slider is fixedly connected to the cross plate.

[0011] By adopting the above technical solution, the lead screw motor can drive the lead screw to rotate, thereby driving the lead screw slider to rise and fall along the strip groove, thus driving the horizontal plate to rise and fall, and in turn driving the oil tank to rise and fall.

[0012] In a preferred embodiment of this utility model, a limiting groove is provided at the bottom of the adjusting plate, and a matching limiting slider is inserted into both sides of the inner cavity of the limiting groove. The bottom of the limiting slider is fixedly connected to the side plate, and a double-headed electric push rod is fixed in the middle of the inner cavity of the limiting groove. The two ends of the double-headed electric push rod are respectively fixedly connected to the side walls of the two limiting sliders.

[0013] By adopting the above technical solution, the double-headed electric actuator can drive the limit sliders on both sides to move closer or further apart, thereby driving the side plates on both sides to move, and then driving the clamping plates on both sides to clamp or release the oil tank.

[0014] In a preferred embodiment of this utility model, a fan is fixedly connected to the bottom of the outer end of the horizontal plate, and the fan is inclined.

[0015] In a preferred embodiment of this utility model, a suitable rubber pad is glued to each of the four corners of the bottom of the base.

[0016] In a preferred embodiment of this utility model, a drain valve is fixedly connected to the lower back side of the water tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The present application provides a leak detection device for an oil storage tank. The oil tank is clamped by a clamping plate, and then the lifting component lifts the oil tank. Then, the servo motor drives the rotating plate to rotate, so that the oil tank rotates to the upper side of the water tank. Then, the lifting component lowers the oil tank into the water tank, thereby replacing the previous manual loading and unloading, which improves the convenience of operation and reduces the labor intensity of the workers.

[0019] The waterproof motor can drive the clamp to rotate, which in turn rotates the oil tank. This allows the oil tank to rotate during leak testing, so that when a leak occurs on the lower surface of the oil tank, the leak point can be rotated to the upper side, making it easier to observe the air bubbles in the water. This helps to avoid situations where the leak point cannot be observed.

[0020] By using a blower to blow air onto the tested oil tank, residual water stains on its surface are blown away, and the oil tank is driven to rotate, which allows for more thorough drying and helps to avoid dripping during unloading. Attached Figure Description

[0029] Please see Figure 1-3 This utility model provides a technical solution: an oil storage tank leak detection device, including a base 1, a water tank 11 fixedly installed on one side of the top of the base 1, and further including:

[0030] Servo motor 12 is fixedly installed on one side of the top of base 1. A turntable 13 is fixedly connected to the outer end of the drive shaft of servo motor 12. A rotating plate 2 is fixedly connected to the top of turntable 13. A strip groove is opened on one side wall of rotating plate 2, and a lifting component is installed in the strip groove.

[0031] A horizontal plate 24 is connected to a lifting assembly. An adjusting plate 3 is connected to the bottom of the horizontal plate 24. Side plates 31 are connected to both sides of the bottom of the adjusting plate 3. A hollow clamping plate 32 is rotatably installed on the inner wall of the side plate 31. A connecting nozzle 33 is fixedly connected to one side wall of one of the clamping plates 32. A rotary joint 35 is connected to the back of the clamping plate 32 corresponding to the connecting nozzle 33. The rotary joint 35 passes through the side plate 31 and is connected to an air source pipe 36. A waterproof motor 34 is fixed to the outer wall of the other side plate 31. The drive shaft of the waterproof motor 34 passes through the side plate 31 and is fixedly connected to the clamping plate 32.

[0032] It should be understood that in actual use, the lifting assembly first lowers the horizontal plate 24, thereby lowering the side plates 31 on both sides. Then, the oil tank is placed between the two clamping plates 32, and the oil inlet at the end of the oil tank aligns with the connecting nozzle 33. Then, the adjusting plate 3 moves the side plates 31 towards the center, thereby clamping the oil pipe with the clamping plates 32 on both sides, and inserting the connecting nozzle 33 into the oil inlet to seal it. Then, the lifting assembly raises the oil tank, and the servo motor 12 drives the rotating plate 2 to rotate, thereby rotating the oil tank to the upper side of the water tank 11. Then, the lifting assembly lowers the oil tank again, so that the oil tank... The water is submerged in the water tank 11, and then gas is introduced into the rotary joint 35 through the air source pipe 36. The gas then enters the connecting nozzle 33 through the cavity of the clamp 32 and enters the oil tank. When there is a leak in the oil tank, bubbles will appear in the water in the water tank 11. The waterproof motor 34 drives the oil tank to rotate, so that when there is a leak on the lower surface of the oil tank, the leak point can be rotated to the upper side, making it easier to see the bubbles in the water. This helps to avoid the situation where the leak point cannot be observed. At the same time, it replaces the previous manual loading and unloading, which improves the convenience of operation and reduces the labor intensity of the workers.

[0033] Furthermore, a drain valve is fixedly connected to the lower back of the water tank 11, which facilitates the drainage of unused water from the water tank 11.

[0034] Furthermore, the four corners of the bottom of the base 1 are glued with matching rubber pads. The rubber pads improve the overall anti-slip performance of the device, which helps to improve the stability during use.

[0035] like Figure 1 and 2 As shown; the lifting assembly includes:

[0036] A lead screw motor 21 is fixedly installed at the bottom of the inner cavity of the strip groove. A lead screw 22 is fixedly connected to the outer end of the drive shaft of the lead screw motor 21. The top of the lead screw 22 is rotatably connected to the inner wall of the strip groove. A suitable lead screw slider 23 is fitted on the outer wall of the lead screw 22. The outer wall of the lead screw slider 23 is fixedly connected to the cross plate 24.

[0037] It should be understood that the lead screw motor 21 can drive the lead screw 22 to rotate, thereby driving the lead screw slider 23 to rise and fall along the strip groove, thereby driving the horizontal plate 24 to rise and fall, and thus driving the oil tank to rise and fall.

[0038] like Figure 1 and 2 As shown; a limiting groove is provided at the bottom of the adjusting plate 3, and a matching limiting slider 38 is inserted into both sides of the inner cavity of the limiting groove. The bottom of the limiting slider 38 is fixedly connected to the side plate 31. A double-headed electric push rod 37 is fixed in the middle of the inner cavity of the limiting groove. The two ends of the double-headed electric push rod 37 are fixedly connected to the side walls of the two limiting sliders 38 respectively.

[0039] It should be understood that the double-headed electric actuator 37 can drive the limit sliders 38 on both sides to move closer or further apart, thereby driving the side plates 31 on both sides to move, and thus driving the clamping plates 32 on both sides to clamp or release the oil tank.

[0040] like Figure 1 and 2 As shown; a fan 25 is fixedly connected to the bottom outer end of the horizontal plate 24, and the fan 25 is set at an angle;

[0041] It should be understood that after the oil tank is lifted out of the water, the blower 25 can be used to blow air onto it, thereby blowing away the water stains remaining on its surface and driving the oil tank to rotate, which can dry it more thoroughly. This helps to avoid dripping when unloading the oil.

[0042] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
