[0035] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0036] Example 1
[0037] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, provides a collection mechanism, which includes: a collection unit 100.
[0038] Among them, the collecting component 101 includes an intercepting plate 101d arranged inside the collecting component 101, a filter plate 101c arranged at the bottom of the intercepting plate 101d, a trapezoidal guide plate 101b arranged at the bottom of the filter plate 101c, and a conveying ring 101a arranged at the bottom of the trapezoidal guide plate 101b. The length of the filter hole on the surface of the intercepting plate 101d is smaller than the sand, so the leaked crude oil can be initially intercepted, and the sand larger than the filter hole diameter can be intercepted. Secondly, the intercepted crude oil is filtered again through the filter plate 101c, and is guided and collected through the trapezoidal guide plate 101b at the bottom.
[0039] Furthermore, the separation component 103 includes a trapezoidal filter plate 103a arranged inside the separation component 103, an oil storage cylinder 103b arranged at the bottom of the trapezoidal filter plate 103a, and an impurity conveying pipe 103c arranged at the bottom of the oil storage cylinder 103b, and the impurity conveying pipe 103c is arranged through the bottom of the collection component 101, and the crude oil that has been filtered and collected passes through the trapezoidal filter plate 103a and is separated from impurities again under the influence of gravity, so that the filtered crude oil is collected inside the external oil storage cylinder 103b, and the separated impurities are collected inside the oil storage cylinder 103b.
[0040] Furthermore, the separation component 103 includes an oil pipeline 103d arranged at the bottom of the separation component 103, and the oil pipeline 103d runs through the bottom of the collection component 101. Clean crude oil can be transported out through the oil pipeline 103, and separated impurities can be removed through the impurity transport pipe 103c.
[0041] During use, when the internal crude oil leaks at the beginning, the leaked crude oil leaks through the top of the inner tube 105, and the crude oil is initially intercepted by the interception plate 101. The length of the filter hole on the surface of the interception plate 101d is smaller than the sand, so the leaked crude oil can be initially intercepted, and the sand with a larger diameter than the filter hole can be intercepted. The interception plate 101d is set with oleophobic material, and the intercepted crude oil is filtered and intercepted for the second time through the filter plate 101c, and its impurities are intercepted on the surface. The filtered and intercepted crude oil is filtered and intercepted through the trapezoidal guide plate 101b. The crude oil is guided into the oil storage barrel 103b through the conveying ring 101a. The particles in the crude oil will directly fall into the oil storage barrel 103b under the influence of gravity through the trapezoidal filter plate 103a on the top of the oil storage barrel 103b, and the crude oil will be diverted to the outside of the oil storage barrel 103b for collection. Finally, the filtered crude oil is conveyed and used through the oil pipeline 103c, and the impurities are discharged through the impurity conveying pipe 103c, so that the impurities in the crude oil are separated and filtered again, and the leaked crude oil can also be well collected and then discharged for use.
[0042] Example 2
[0043] Reference Figure 3 and Figure 4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: the monitoring unit 200 includes a monitoring component 201 arranged on the outer diameter of the collecting component 101.
[0044] Compared with Example 1, a further monitoring component 201 includes a fixed ring 201a arranged on the monitoring component 201 and located on the outer diameter of the collecting component 101, a support rod 201b arranged on the fixed ring 201a, a buffer rod 201c arranged on the support rod 201b, a block 201d slidably arranged on the buffer rod 201c, and an alarm 201e arranged on the block 201d and linked with the buffer rod 201c. Through the monitoring component 201, when the sucker rod 104 inside the inner tube 105 is offset, the top block 201d is simultaneously offset by the sucker pipe 104, and the buffer rod 201c is squeezed at the same time. The buffer rod 201c moves after being squeezed, so that the buffer rod 201c touches the alarm 201e, so that the alarm 201e starts to work and alarms for prompting.
[0045] Among them, a top shell 102 is arranged on the upper part of the collection component 101, an inner tube 105 is arranged at the bottom of the collection component 101, a sucker rod 104 is slidably arranged on the top shell 102, and the sucker rod 104 is slidably connected to the inner tube 105, and the sucker rod 104 performs normal sliding work inside the inner tube 105.
[0046] During use, initially, when the sucker rod 104 is sliding normally inside the inner tube 105, the block 201a limits the movement of the sucker rod, and the sucker rod 104 moves up and down inside the block 201a. However, when the sucker rod 104 deviates and moves, the block 201a is squeezed to both sides. When the block 201a is squeezed, the buffer rod 201c is squeezed. At the same time, the buffer rod 201c touches the alarm 201e through the squeezing movement, and the alarm 201e starts to alarm, prompting the staff that the sucker rod 104 is deviated to avoid a major leakage incident.
[0047] The remaining structures are the same as those of Example 1.

[0054] Preferably, the oil head assembly 402 is connected to the oil pipe 401 , and the oil head assembly 402 normally extracts crude oil from the bottom through the connection with the oil pipe 401 .
[0055] During use, when the oil head is working normally, the ground is stabilized and fixed through the oil pipe 401, and the crude oil extracted from the bottom is transported through the oil head assembly 402. At the same time, the branch pipes 402b on both sides of the oil head assembly 402 are used to disperse and transport the extracted crude oil.
