Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, in particular to a storage and adding device for low-temperature corrosion inhibitors. Background Art

[0002] Corrosion inhibitors are chemical substances or compounds that exist in the environment in appropriate concentrations and forms and can prevent or slow down the corrosion of materials. Therefore, corrosion inhibitors can also be called corrosion inhibitors. A small amount of corrosion inhibitors can avoid local corrosion of equipment and pipelines, have a significant protective effect, and have high economic benefits in the processing and production of petroleum products.

[0003] The utility model with authorization announcement number CN215400293U provides an oilfield corrosion inhibitor storage device, which realizes the transfer of the storage device by driving the wheels through an engine, and uses a frame composed of a protective layer to form a double-layer protection to avoid liquid leakage caused by damage to the internal structure due to long storage time, thereby increasing the service life of the storage device.

[0004] However, in the above patent, the storage device is transferred by driving the wheels by the engine. When a large amount of corrosion inhibitor is stored inside the storage device, the pressure exerted by the device on the wheels is relatively large. When the device transports the storage device to soft ground, there is a possibility that the wheels will sink into the ground and be inconvenient for subsequent transportation. At the same time, when the ground where the storage device rests has a certain slope, there is a possibility that the storage device will slip and cause the storage device to overturn. In view of this, we propose a storage and addition device for low-temperature corrosion inhibitors. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] See also Figure 1-Figure 5As shown, the present embodiment aims to provide a storage and addition device for low-temperature corrosion inhibitor, including a base 1, a storage tank 2 is fixedly connected to the top of the base 1, a pedal 3 is provided on the sliding sleeve of the outer wall of the storage tank 2, a lifting mechanism 4 is provided between the pedal 3 and the base 1, the lifting mechanism 4 is used to drive the pedal 3 to move vertically, and universal wheels 6 are installed near the four corners of the lower surface of the pedal 3, and the lower ends of the universal wheels 6 extend to the bottom of the base 1. After the four universal wheels 6 touch the ground, it is convenient to push the base 1 to move so as to transport the storage tank 2. After the storage tank 2 is transported to the predetermined location, the lifting mechanism 4 drives the pedal 3 and the four universal wheels 6 to move vertically upward until the four universal wheels 6 are moved to the top of the base 1 so that the base 1 touches the ground, which can enhance the stability of the storage tank 2 in a static state and avoid In order to prevent the universal wheel 6 from being damaged due to long-term high pressure, anchoring mechanisms 5 are provided at the top of the base 1 near the four corners, and the anchoring mechanisms 5 include anchor rods 53. The side wall of the base 1 is provided with eight through grooves, and the eight through grooves are movably mounted on the outside of the four anchor rods 53 and the four universal wheels 6. When the pedal 3 moves vertically, the anchor rod 53 moves vertically in the opposite direction. A drilling depth assembly 57 is provided on the outside of the anchor rod 53. When the anchor rod 53 moves vertically, the drilling depth assembly 57 drives the anchor rod 53 to rotate. In the process that the lifting mechanism 4 drives the pedal 3 and the universal wheel 6 to move vertically upward, the anchor rod 53 moves vertically downward while continuously rotating until the anchor rod 53 is drilled into the soil, thereby anchoring the base 1 and further enhancing the stability of the storage tank 2 in a static state.

[0028] When the base 1 is placed on the ground with a certain slope, in order to prevent the base 1 from sliding, an anchoring mechanism 5 is arranged on the base 1, and the structure of the anchoring mechanism 5 is refined. The anchoring mechanism 5 also includes two vertical poles 51 fixedly connected to the upper surface of the base 1, and the outer walls of the two vertical poles 51 are slidably sleeved with a slide plate 52, and the anchor rod 53 is rotatably connected to the side wall of the slide plate 52. A first rack 54 is fixedly connected to one side of the slide plate 52, and a second rack 55 is fixedly connected to the lower surface of the pedal 3. A transmission gear 56 is rotatably connected to the upper surface of the base 1, and the first rack 54 and the second rack 55 are both meshed with the transmission gear 56. When the pedal 3 drives the second rack 55 to move vertically upward, the transmission gear 56 drives the first rack 54 to move vertically downward, and then the slide plate 52 drives the anchor rod 53 to move downward synchronously, so that the lower end of the anchor rod 53 moves to the bottom of the base 1, and the anchor rod 53 is inserted into the ground soil, so as to anchor the base 1 and prevent the base 1 from sliding on the slope and affecting the stability of the storage tank 2.

[0029] In order to enable the anchor rod 53 to rotate while moving downward and to make the anchor rod 53 easier to insert into the soil, a drilling depth assembly 57 is arranged on the outer side of the anchor rod 53, and the structure of the drilling depth assembly 57 is refined. The drilling depth assembly 57 includes a fixed gear 571 fixedly connected to the outer wall of the circumference of the anchor rod 53, a third rack 572 is slidably connected to the bottom of the slide plate 52, the third rack 572 is meshed with the fixed gear 571, one end of the third rack 572 is fixedly connected to a slider 573, and an inclined groove frame 574 is fixedly connected to the upper surface of the base 1, and the inclined groove frame 574 is slidably sleeved on the outer side of the slider 573. During the vertical downward movement of the slide plate 52, the third rack 572 is driven to move downward synchronously, and the slider 573 slides along the inner wall of the inclined groove frame 574, so that the slider 573 drives the third rack 572 to move horizontally during the vertical downward movement, and the meshing transmission between the third rack 572 and the fixed gear 571 makes the anchor rod 53 rotate during the vertical downward movement.

[0030] In order to drive the pedal 3 to move vertically, a lifting mechanism 4 is set between the base 1 and the pedal 3, and the structure of the lifting mechanism 4 is refined. The lifting mechanism 4 includes two cross hinges 41 hinged on the upper surface of the base 1, and the upper ends of the cross hinges 41 are hinged to the lower surface of the pedal 3. Two linkage rods 42 are arranged between the base 1 and the pedal 3, and the two ends of the linkage rod 42 are respectively rotatably connected to the ends of the two cross hinges 41. The outer wall of the circumference of the linkage rod 42 is movably sleeved with two frames 44, and the four frames 44 are respectively fixedly connected to the upper surface of the base 1 and the lower surface of the pedal 3. A screw rod 43 is threadedly connected to the linkage rod 42 at the bottom, and the two ends of the screw rod 43 are connected to the upper surface of the base 1. The surface is rotated and connected. When the screw rod 43 rotates, the threaded connection between the screw rod 43 and the linkage rod 42 allows the linkage rod 42 to approach the step plate 7 along the axial direction of the screw rod 43. The two ends of the moving linkage rod 42 are restricted by the frame 44, so that the linkage rod 42 moves smoothly on the base 1. During the movement of the linkage rod 42, the linkage rod 42 pulls one end of the cross hinge 41, so that one end of the cross hinge 41 moves horizontally with the linkage rod 42. During the translation of the cross hinge 41, the ends of the cross hinge 41 approach each other, so that the cross hinge 41 drives the pedal 3 to move upward, thereby adjusting the distance between the base 1 and the pedal 3.

[0031] An embedded groove is provided on one side of the pedal 3, and a step plate 7 is fixedly connected to the inner wall of the embedded groove. A feed pipe is fixedly connected to the top of the storage tank 2, and an end cap is threadedly connected to the outer wall of the feed pipe near the upper end. When it is necessary to add low-temperature corrosion inhibitor to the storage tank 2, the lower surface of the base 1 is made to touch the ground, and the pedal 3 drives the step plate 7 to move vertically upward. The distance between the pedal 3 and the feed pipe is shortened, so that after the worker steps on the step plate 7 and walks above the pedal 3, it is convenient to unscrew the end cap and add low-temperature corrosion inhibitor to the storage tank 2. A discharge pipe is fixedly connected to the side wall of the storage tank 2 between the base 1 and the pedal 3, and a valve body is installed on the inner wall of the discharge pipe. When it is necessary to take the low-temperature corrosion inhibitor in the storage tank 2, the valve body is opened to discharge the low-temperature corrosion inhibitor in the storage tank 2 through the discharge pipe.

[0032] In summary, the working principle of the present scheme is as follows: when the low-temperature corrosion inhibitor needs to be transported to a predetermined location outdoors, the device is placed in a state where the universal wheels 6 touch the ground. After pushing the base 1 and the pedal 3 to transport the low-temperature corrosion inhibitor in the storage tank 2 to the predetermined location, the screw 43 is rotated to move the pedal 3 vertically upward until the pedal 3 drives the four universal wheels 6 to move above the base 1 so that the base 1 touches the ground, thereby enhancing the stability of the storage tank 2 placed at the predetermined location and preventing the universal wheels 6 from being damaged due to long-term and heavy pressure. During the vertical upward movement of the pedal 3, the anchor rod 53 moves vertically downward. While the anchor rod 53 moves vertically downward, it also continues to rotate, so that the anchor rod 53 can easily drill into the ground soil. After the anchor rod 53 drills into the soil, it anchors the base 1, thereby enhancing the stability of the storage tank 2 in a static state.
