Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction pumps, and particularly relates to an anti-sand oil extraction pump. Background Technique

[0002] Oil is an indispensable energy or resource for the development of modern society. After oil is extracted and refined, it can be divided into various products such as gasoline, aviation kerosene, diesel oil, and machine oil, providing energy for almost all machines such as cars, airplanes, and ships. Oil takes tens of millions of years to form and is formed by the decay of ancient trees and the like.

[0003] In the process of implementing this application, it is found that there are the following problems in this technology: Most of the existing oil extraction pumps use a filtering method to reduce the entry of sand and gravel into the interior of the oil extraction pump during the oil extraction process. However, most of the sand and gravel are easily stuck inside the filter screen, and the pipeline is a closed space, making it impossible for subsequent workers to know the reason why the extraction pump reduces the extraction volume.

[0004] Therefore, an anti-sand oil extraction pump is proposed. Content of the Utility Model

However, most of the sand and gravel are easily stuck inside the filter screen, and the pipeline is a closed space, making it impossible for subsequent workers to know the reason why the extraction pump reduces the extraction volume. The utility model provides an anti-sand oil extraction pump.

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0008] Further, the filtering mechanism includes a warning device, a first fixed ring and a second fixed ring. The warning device is installed on the upper surface of the bottom plate. The first fixed ring is slidably connected inside the connecting pipe. The second fixed ring is installed inside the connecting pipe. The position of the second fixed ring is between the first fixed ring and the main body of the oil pump. A filter screen is arranged inside the first fixed ring. A connecting rod is arranged on the inner wall of the second fixed ring. A contact switch is arranged on the side of the connecting rod away from the main body of the oil pump.

The control ends of the contact switch and the warning device are electrically connected.

[0009] Further, a U-shaped groove is formed on the side of the second fixed ring close to the main body of the oil pump. A U-shaped protective cover is slidably connected inside the U-shaped groove of the second fixed ring. One side of the U-shaped protective cover away from the main body of the oil pump is installed on the side of the first fixed ring close to the main body of the oil pump. One side of the U-shaped protective cover away from the contact switch abuts against the inner wall of the connecting pipe. The U-shaped protective cover is sleeved on the outer end of the damping spring.

[0010] Further, the protection mechanism includes a U-shaped protective cover plate. The U-shaped protective cover plate is slidably connected inside the card slot of the bottom plate. Grooves are formed on the upper surfaces of the bottom plate and the U-shaped protective cover plate. A positioning plate is slidably connected inside the groove of the U-shaped protective cover plate. The position of the groove inside the bottom plate is on the moving path of the bottom end of the positioning plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, by arranging the filter screen inside the connecting pipe, the filter screen filters the petroleum guided by the connecting pipe into the connecting pipe, thereby minimizing the subsequent entry of sand and gravel into the interior of the petroleum pump main body and preventing blockage inside the petroleum pump main body; when the petroleum is transported inside the connecting pipe, the pressure generated pushes a pair of damping springs of the fixed ring to drive the fixed ring one to slide inside the connecting pipe. Then, since the position of the contact switch is on the moving path of the filter screen, when the filter screen moves subsequently, the contact switch is triggered to start the warning device to emit a warning sound, which facilitates subsequent workers to promptly disassemble and move the connecting pipe to clean or replace the interior of the filter screen, thus improving the practicality of the device.

[0015] 2.

Then, by pushing the positioning plate, the bottom end of the positioning plate is clamped inside the groove of the bottom plate, so that the protective mechanism is installed and positioned at the outer end of the bottom plate. And since the lower surface of the bottom plate and the upper surface of the U-shaped protective cover plate are both flat, the device can be stacked and transported during subsequent storage and transportation, thereby reducing the occupied area consumed during the subsequent transportation of the device, and further reducing the transportation cost consumed during the subsequent transportation of the device, thus improving the practicality of the device.

[0025] like Figures 1 to 4 As shown, a sand-proof oil production pump comprises an oil pump body 1, the oil pump body 1 comprises a connecting pipe 2 and a bottom plate 6, a card slot is provided on a side of the bottom plate 6 away from the connecting pipe 2, a protective mechanism 4 is slidably connected inside the card slot of the bottom plate 6, a filtering mechanism 3 is provided inside the connecting pipe 2 to prevent the connecting pipe 2 from being blocked, and the filtering mechanism 3 is installed on the inner wall of the connecting pipe 2; specifically, the filter net 302 is arranged inside the connecting pipe 2 so that the filter net 302 filters the oil guided into the connecting pipe 2 by the connecting pipe 2, thereby avoiding as much as possible the subsequent sand and gravel from entering the inside of the oil pump body 1 and causing blockage inside the oil pump body 1; a warning sound is emitted when blockage occurs inside the filtering mechanism 3, thereby facilitating the subsequent staff to dismantle and move the connecting pipe 2 in time to clean or replace the filtering equipment inside the filtering mechanism 3.

[0026] like Figure 2 and Figure 3As shown in the figure, the filtering mechanism 3 includes a warning device 301, a first fixed ring 303 and a second fixed ring 305. The warning device 301 is installed on the upper surface of the bottom plate 6. The first fixed ring 303 is slidably connected inside the connecting pipe 2. The second fixed ring 305 is installed inside the connecting pipe 2. The position of the second fixed ring 305 is between the first fixed ring 303 and the main body 1 of the oil pump. A filter screen 302 is arranged inside the first fixed ring 303. A connecting rod 306 is arranged on the inner wall of the second fixed ring 305. A contact switch 307 is arranged on the side of the connecting rod 306 away from the main body 1 of the oil pump. The position of the contact switch 307 is on the moving path of the filter screen 302. A damping spring 304 is arranged on the side of the second fixed ring 305 close to the first fixed ring 303. One end of the damping spring 304 away from the second fixed ring 305 is installed on the side of the first fixed ring 303 close to the main body 1 of the oil pump. An electrical connection is made between the control ends of the contact switch 307 and the warning device 301;

[0027] Specifically, by arranging the filter screen 302 inside the connecting pipe 2, the filter screen 302 filters the oil guided by the connecting pipe 2 into the connecting pipe 2, so as to avoid subsequent sand and gravel from entering the main body 1 of the oil pump and causing blockage inside the main body 1 of the oil pump as much as possible; when the inside of the filter screen 302 is blocked, the pressure generated by the oil conveyed inside the connecting pipe 2 pushes the first fixed ring 303 to squeeze the damping spring 304, driving the first fixed ring 303 to slide inside the connecting pipe 2. Then, because the position of the contact switch 307 is on the moving path of the filter screen 302, when the filter screen 302 moves later, it triggers the contact switch 307 to start the warning device 301 to emit a warning sound, so as to facilitate the subsequent staff to disassemble and move the connecting pipe 2 in time to clean or replace the inside of the filter screen 302, thus improving the practicability of the device.

[0028] As Figure 3 shown in the figure, a U-shaped groove is opened on the side of the second fixed ring 305 close to the main body 1 of the oil pump. A U-shaped protective cover 5 is slidably connected inside the U-shaped groove of the second fixed ring 305. One side of the U-shaped protective cover 5 away from the main body 1 of the oil pump is installed on the side of the first fixed ring 303 close to the main body 1 of the oil pump. One side of the U-shaped protective cover 5 away from the contact switch 307 abuts against the inner wall of the connecting pipe 2. The U-shaped protective cover 5 is sleeved on the outer end of the damping spring 304; specifically, by sleeving the U-shaped protective cover 5 on the outer end of the damping spring 304, the U-shaped protective cover 5 shields and seals the use space of the damping spring 304 inside the connecting pipe 2, so as to avoid subsequent contact between the damping spring 304 and the original inside of the input connecting pipe 2 during idling or use, resulting in blockage inside the damping spring 304 as much as possible.

[0029] As Figure 1 、 Figure 2and Figure 4 As shown, the protection mechanism 4 includes a U-shaped protection cover plate 401, which is slidably connected to the inside of the card slot of the bottom plate 6, and the upper surfaces of the bottom plate 6 and the U-shaped protection cover plate 401 are provided with grooves, and a positioning plate 402 is slidably connected to the inside of the groove of the U-shaped protection cover plate 401, and the position of the groove inside the bottom plate 6 is located on the moving path of the bottom end of the positioning plate 402, and a card slot is opened on the side of the U-shaped protection cover plate 401 close to the connecting pipe 2, and a magnetic block 403 is arranged inside the card slot of the U-shaped protection cover plate 401, and the side of the magnetic block 403 away from the U-shaped protection cover plate 401 is adsorbed on the inner side wall of the card slot of the bottom plate 6, and the position of the groove inside the bottom plate 6 is located on the side of the connecting pipe 2 away from the oil pump body 1;

[0030] Specifically, the U-shaped protective cover 401 is pushed to adsorb the magnetic block 403 away from the side of the U-shaped protective cover 401 on the inner wall of the bottom plate 6 slot, and then the positioning plate 402 is pushed to clamp the bottom end of the positioning plate 402 inside the groove of the bottom plate 6, so that the protective mechanism 4 is installed and positioned at the outer end of the bottom plate 6, and the lower surface of the bottom plate 6 and the upper surface of the U-shaped protective cover 401 are both set as planes, so that the device can be stacked and transported during storage and transportation, thereby reducing the occupied area consumed by the device during transportation, and then reducing the transportation cost consumed by the device during transportation, thereby improving the practicality of the device; a group of rectangles are formed by the protective mechanism 4 and the bottom plate 6 to wrap the outer end of the oil pump body 1, so as to avoid the subsequent oil pump body 1 from being hit during the transportation and movement, thereby improving the service life of the oil pump body 1.

[0031] like Figure 1 and Figure 2 As shown, the fixing plate 7 on the lower surface of the base plate 6 and the upper surface of the U-shaped protective cover plate 401 are provided with positioning grooves, and the positioning groove of the U-shaped protective cover plate 401 is located at the upper end of the fixing plate 7, and the inner contour of the positioning groove of the U-shaped protective cover plate 401 is adapted to the outer contour of the fixing plate 7; specifically, by moving the base plate 6, a group of fixing plates 7 at the lower end of the base plate 6 are clamped in the positioning grooves of the U-shaped protective cover plate 401 at the outer end of another group of oil pump bodies 1, so that the subsequent fixing plates 7 and the protective mechanism 4 limit the moving position of the oil pump bodies 1 when multiple groups of oil pump bodies 1 are stacked, thereby improving the stability of the subsequent multiple groups of oil pump bodies 1 when they are stacked together, thereby improving the practicality of the device.

[0032] like Figure 1As shown in the figure, a clamping groove is formed on the front surface of the positioning plate 402, and a limiting rod 8 is slidably connected inside the clamping groove of the positioning plate 402; specifically, when a part of the subsequent positioning plate 402 moves to the upper end of the U-shaped protective cover plate 401, by pushing the limiting rod 8, the limiting rod 8 is pushed out of the clamping groove of the positioning plate 402 and abuts against the upper surface of the U-shaped protective cover plate 401, so that the limiting rod 8 restricts the position of the positioning plate 402 from moving downward inside the groove of the U-shaped protective cover plate 401, thereby minimizing the risk that the positioning plate 402 slides downward during the subsequent pulling of the U-shaped protective cover plate 401 and collides with the outer surface of the oil pump main body 1, resulting in damage to the oil pump main body 1.

[0033] In summary: By setting the position of the filter screen 302 inside the connecting pipe 2, the filter screen 302 filters the oil guided by the connecting pipe 2 into the connecting pipe 2, thereby minimizing the risk that subsequent sand and gravel enter the inside of the oil pump main body 1 and cause blockage inside the oil pump main body 1; when the oil is transported inside the connecting pipe 2, the pressure generated pushes the fixed ring 303 to squeeze the damping spring 304, driving the fixed ring 303 to slide inside the connecting pipe 2. Then, since the position of the contact switch 307 is on the moving path of the filter screen 302, when the subsequent filter screen 302 moves, it triggers the contact switch 307 to start the alarm 301 to emit an alarm sound, facilitating subsequent workers to timely disassemble the movable connecting pipe 2 to clean or replace the inside of the filter screen 302.

[0034] Meanwhile, by pushing the U-shaped protective cover plate 401, the side of the magnetic block 403 away from the U-shaped protective cover plate 401 is adsorbed on the inner side wall of the clamping groove of the bottom plate 6. Then, by pushing the positioning plate 402, the bottom end of the positioning plate 402 is clamped inside the groove of the bottom plate 6, so that the protection mechanism 4 is installed and positioned at the outer end of the bottom plate 6. Since the lower surface of the bottom plate 6 and the upper surface of the U-shaped protective cover plate 401 are both flat, the subsequent device can be stacked and transported during storage and transportation, thereby reducing the occupied area consumed during the subsequent transportation of the device.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
