[0053] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0054] A lateral foldable oil storage tank mud removal and reduction processing device and its control system, comprising:

[0055] The base 1 is used to be installed at the bottom side of the oil storage tank; by installing the base 1 at its side, firstly, the distance of the pipeline connection required for external connection in the later stage is shortened, thereby reducing the cost and the degree of instability factors, and secondly, the influence and interference on the normal use of the oil storage tank in the later stage is reduced. The specific installation diagram can be referred to Figure 3 shown.

[0056] The rotating seat 2 is rotatably mounted on the base 1 and is externally connected to a rotating driving mechanism to realize the rotation of the rotating seat 2, thereby achieving adjustment in different angles and directions.

[0057] The lifting rod 3 is arranged on one side of the rotating seat 2 and is provided with a sliding seat 10 which can be lifted and lowered by a lifting driving mechanism;

[0058] The first articulated arm 4 and the first articulated rod 6 have their inner ends respectively hinged to the rotating seat 2 and / or the lifting rod 3, and a first linkage plate 8 is hinged between their outer ends to form a parallelogram articulated structure; the inner ends of the first articulated arm 4 and the first articulated rod 6 can both be hinged to the rotating seat 2, or can both be hinged to the lifting rod 3; or one can be hinged to the rotating seat 2 and the other can be hinged to the lifting rod 3.

[0059] A pulling rod 12, the inner end of which is hinged to the first linkage plate 8;

[0060] The second hinged arm 5 and the second hinged rod 7, the inner ends of the two are respectively hinged to the outer end of the pull rod 12 and the first linkage plate 8, and the second linkage plate 9 is hinged between the outer ends of the two to form a parallelogram hinge structure;

[0061] A linkage rod, one end of which is hinged to the slide seat 10, and the other end of which is hinged to the first hinge arm 4 or the first hinge rod 6;

[0062] The first articulated arm 4 and the second articulated arm 5 are hingedly connected;

[0063] The suction nozzle 17 and the impact nozzle 18 are arranged on the second linkage plate 9 .

[0064] Specifically, the lifting drive mechanism drives the slide 10 to move, thereby driving the first hinged arm 4 to deflect, and then driving the first linkage plate 8 to deflect, and under the pulling of the pulling rod 12, the second hinged arm 5 is deflected, and then the second linkage plate 9 is deflected. Figure 2 As shown, the slide 10 is raised so that the first hinged arm 4 and the second hinged arm 5 are folded and stowed, and the slide 10 is raised so that the first hinged arm 4 and the second hinged arm 5 are straightened and opened.

[0065] In some embodiments, the lifting drive mechanism includes:

[0066] The screw rod 11 is rotatably mounted on one side of the lifting rod 3 and is threadably connected to the sliding seat 10;

[0067] The screw rod rotation driving mechanism is connected to the screw rod 11 to drive the screw rod 11 to rotate.

[0068] The adjustment is specifically carried out by means of screw rod lifting and lowering, and its adjustment control is more precise and reliable, and has a built-in locking effect.

[0069] Specifically, the screw rotation drive mechanism includes:

[0070] The screw rod rotation transmission box is arranged at the lower end of the screw rod 11;

[0071] The screw rod rotating transmission box driving shaft has one end connected to the screw rod rotating transmission box and the other end extending to the outside of the oil storage tank.

[0072] The above arrangement enables the drive motor to be externally arranged, thereby avoiding the need for circuit routing and fundamentally avoiding the hidden dangers caused by power-on.

[0073] In some embodiments, the rotation drive mechanism comprises:

[0074] The rotating gear ring 14 is arranged outside the rotating seat 2;

[0075] The rotating gear 15 is meshed with the rotating gear ring 14;

[0076] The rotating gear driving mechanism 16 is connected to the rotating gear 15 to drive the rotating gear 15 to rotate.

[0077] The use of gears and gear rings for meshing drive not only ensures the reliability of the transmission, but also utilizes the lubricity of the medium in the oil storage tank, eliminating the need for lubrication maintenance and reducing the maintenance cost and burden of the equipment.

[0078] Specifically, the rotary gear driving mechanism 16 includes:

[0079] A rotating gear transmission box is arranged on the base 1;

[0080] The rotary gear transmission box driving shaft has one end connected to the rotary gear transmission box and the other end extending to the outside of the oil storage tank.

[0081] The starting point of the above-mentioned structural setting is consistent with the screw rotation drive mechanism, and is also to avoid circuit cross-wiring, so that the energized drive motor is externalized through an external drive shaft.

[0082] Power is transmitted through the screw rotating transmission box drive shaft and the rotating gear transmission box drive shaft, and because the base 1 is located on the bottom side of the oil storage tank, it does not need to be set up for a long distance inside it. When setting it up, it is only necessary to ensure that there is a good dynamic sealing structure between the drive shaft and the oil storage tank.

[0083] In some embodiments, it also includes:

[0084] The upper limit plate and the lower limit plate are arranged at the upper and lower ends of the screw rod 11 to limit the lifting position of the slide 10;

[0085] When the slide 10 moves to the upper limit plate, the first hinged arm 4 and the second hinged arm 5 are in an extreme folded and retracted state;

[0086] When the slide seat 10 moves to the lower limit plate, the first articulated arm 4 and the second articulated arm 5 are in an extreme open state.

[0087] By means of mechanical limiting, the adjustment range of the opening and closing angle between the first articulated arm 4 and the second articulated arm 5 is limited, and it is ensured that it can cover the entire bottom of the oil storage tank.

[0088] In some embodiments, the suction nozzle 17 and the impact nozzle 18 are arranged on both sides of the second linkage plate 9 and are respectively connected to external connection pipelines.

[0089] In some embodiments, the connecting line includes:

[0090] The first straight tube 19 and the second straight tube 20 are straight tubes of rigid structure and are respectively arranged on the second articulated arm 5 and the first articulated arm 4;

[0091] The connecting hose 21 is a hose with a flexible structure and is disposed between the first straight tube 19 and the second straight tube 20 and is located at the hinge of the second articulated arm 5 and the first articulated arm 4 .

[0092] Rigid structural branches are used in straight sections to ensure pipeline strength, and flexible hoses are used at bends to ensure normal bending.

[0093] In some embodiments, the first articulated arm 4 and the second articulated arm 5 are single-layer plate structures; the first linkage plate 8, the second linkage plate 9, the first articulated rod 6, the second articulated rod 7, the pulling rod 12 and the linkage rod are double-plywood structures and are located on both sides of the first articulated arm 4 and the second articulated arm 5.

[0094] The above structural arrangement can ensure the stability and reliability of the transmission force and the rigid mechanical strength during the transmission process.

[0095] A control system, comprising: a sludge removal and reduction processing device for a side-standing foldable oil storage tank and an electronic control system as in any one of the above embodiments;

[0096] The electric control system is electrically connected to the rotating drive mechanism and the lifting drive mechanism to monitor the rotating direction of the rotating base 2 and the folding state between the first articulated arm 4 and the second articulated arm 5 .

[0097] Its working principle is:

[0098] According to the size range of the bottom of the oil storage tank (usually a circular tank body), the length of the first articulated arm 4 and the second articulated arm 5 is determined, and the number of rotations of the screw rod 11 is set through the limit range of the two ends during the actual opening and closing angle adjustment process. At the same time, the upper limit plate and the lower limit plate are cooperated to form a mechanical limit to avoid mechanical interference of the equipment.

[0099] Four pipeline openings need to be started on one side of the bottom of the oil storage tank, two of which are the drive shaft of the screw rotary transmission box and the drive shaft of the rotary gear transmission box, and two of which are external pipelines of the suction nozzle 17 and the impact nozzle 18. The former provides a source of power drive, and the latter provides suction and impact force for removing sludge.

[0100] During operation, the electric control system is used to control the rotation angle of the rotating seat 2 and the nozzle positions of the suction nozzle 17 and the impact nozzle 18 to process the sludge at the bottom. The impact nozzle 18 flushes the sludge by injecting high-pressure medium, and then cooperates with the high-pressure adsorption of the suction nozzle 17 to bring the sludge out, thereby completing the entire cleaning operation.

[0101] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
