Description

Technical Field

[0001] This utility model belongs to the technical field of tank sweeping rotor pumps, specifically an automatic speed-regulating oil unloading tank sweeping rotor pump that can be adsorbed onto the ship deck. Background Technology

[0002] The sump pump is a positive displacement pump with a cam rotor as its core. Two opposing rotating synchronous gears drive a rotor mounted on two parallel shafts. A sealed cavity is continuously formed between the fully rubber-coated rotor and the pump casing. The medium filled in the cavity is continuously pushed from the inlet to the outlet by the rotating rotor. A vacuum is created at the pump suction end, continuously drawing in the medium, which is then discharged through the sealed cavity from the discharge end. As a positive displacement pump, the sump pump has low wear and low speed, making it suitable for many applications, including solid, viscous, and fibrous materials. This also contributes to its stable operation. The sump pump's drive and transmission are separate, and it has a pair of synchronous gears, resulting in high efficiency. The sump pump also boasts advantages such as small size and ease of maintenance. On-site maintenance is convenient; simply opening the pump cover at the liner end allows for quick and easy replacement of easily worn parts.

[0003] In the prior art, Chinese patent CN222991703U discloses a dry-rotation resistant rotor pump, which relates to the field of rotor pump technology. The rotor pump includes a fixed frame, a drive seat is provided above the fixed frame, a pump body is installed on one side of the drive seat, an oil inlet is provided on the top of the pump body, a pump cover is installed on one side of the pump body, a liner is installed on the inner wall of the pump body, two rotors are installed inside the liner, a rotating shaft is provided inside the rotor, liquid level sensors are installed on the upper and lower end faces inside the liner, and six oil injection rollers are provided on both side end faces of the liner.

[0004] However, the rotor pump provided in the above technical solution still has many shortcomings in actual use. For example, when cleaning the tanks of a ship for unloading oil, it is not possible to quickly and easily place the cleaning rotor pump stably on the ship deck. This makes it time-consuming to adjust the position of the rotor pump during cleaning, which affects the efficiency of cleaning and unloading oil and results in poor practicality.

The rollers 13 are symmetrical about the vertical center line of the drive box 12, and the vertical center line of the drive box 12 coincides with the vertical center line of the base 1. Through the drive motor inside the drive box 12, in conjunction with the rolling of the rollers 13, the device can be moved to a designated location, making the device easy to move.

[0027] In this embodiment, a pump housing 2 is fixedly connected to the top of the base 1. The pump housing 2 contains a rotor, a rotating shaft, and a negative pressure sensing device.

A crossbar 7 is fixedly connected to the end of the mechanical arm 6. Movable suction cups 8 are provided on both sides of the crossbar 7. By pressing the suction cups 8 with the mechanical arm 6, the suction cups 8 come into contact with the ship deck, thus fixing the device to the ship deck. This allows for quick and convenient installation and fixing of the device during use, improving its practicality.

[0028] In this embodiment, slots 9 are provided on both sides of the crossbar 7, and the slots 9 penetrate the top and bottom of the crossbar 7. A connecting tube 10 is slidably connected inside the crossbar 7. The bottom end of the connecting tube 10 is threadedly connected to the suction cup 8. The robotic arm 6 is symmetrical about the vertical center line of the pump housing 2, and the slots 9 are symmetrical about the vertical center line of the crossbar 7. The connecting tube 10 penetrates the slot 9, and a locking ring 11 is threadedly connected to the outside of the connecting tube 10. Tightening the locking ring 11 can restrict the sliding of the connecting tube 10 in the slot 9. Before use, loosening the locking ring 11, in conjunction with the sliding of the connecting tube 10 in the slot 9, can adjust the distance between the two suction cups 8 on the same crossbar 7. In conjunction with the robotic arm 6, the position of the crossbar 7 can be adjusted, thereby adjusting the adsorption point of the device. This allows the device to be used in different locations on the ship deck, improving the applicability of the device.

[0029] In this embodiment, a lightweight groove is provided at one end of the base 1. The oil inlet pipe 3 and the oil outlet pipe 4 are symmetrical about the vertical center line of the pump housing 2. The output shaft of the motor 5 passes through one side of the pump housing 2 and is fixedly connected to the rotating shaft. The lightweight groove on the base 1 can reduce the weight of the base 1 and facilitate the handling of the device. The device can be connected to external oil conveying equipment through the oil inlet pipe 3 and connected to external oil discharge equipment through the oil outlet pipe 4. The oil conveying equipment end is placed in the oil tank, the motor 5 is started, and with the use of the internal components of the pump housing 2, the oil in the oil tank can be extracted to achieve the purpose of cleaning the tank.

[0030] In this embodiment, a sealing cover 15 is threadedly connected to one side of the pump body housing 2.

[0032] Working principle: When using this device, the drive motor inside the drive box 12, in conjunction with the rolling of the rollers 13, moves the device to a designated location, making it easy to move. The robotic arm 6 presses the suction cups 8, making them contact the ship's deck and fixing the device to the deck. This allows for quick and convenient installation and fixation, improving the device's practicality. Before use, loosening the locking ring 11, along with the sliding of the connecting tube 10 in the slot 9, allows adjustment of the distance between the two suction cups 8 on the same crossbar 7. The position of the crossbar 7 is adjusted by the robotic arm 6, thereby adjusting the suction point of the device. This allows the device to be used in different locations on the ship's deck, improving its applicability.
