Description

TECHNICAL FIELD

[0001] The present application relates to the field of oilfield equipment, in particular to an anti-impact protection device. BACKGROUND

[0002] At present, in the process of oilfield operation, when the wellhead is accidentally broken, high-pressure water flow or wellhead structure may be sprayed out, and the high-pressure water column or structure is not blocked, which may cause harm to the operator and damage the equipment around the wellhead. SUMMARY

[0003] In order to overcome the harm caused by the high-pressure water flow or wellhead structure to the operator, the present application provides an anti-impact protection device, which has good anti-impact performance and can avoid harm to the operator caused by the high-pressure water column or wellhead structure.

[0004] The technical scheme of the present application is: an anti-impact protection device, comprising a top plate and a bottom plate, at least two vertical plates are connected between the top plate and the bottom plate, a plurality of water permeable holes are formed in each vertical plate except the last vertical plate, and a plurality of inclined plates are connected between adjacent vertical plates, and the inclined plates are located behind the water permeable holes.

[0005] The water permeable holes on adjacent two layers of vertical plates are staggered in the horizontal direction.

[0006] The width of the inclined plate is not less than the width of the water permeable hole.

[0007] The vertical plate is three layers, and the inclined plate between the first layer of vertical plate and the second layer of vertical plate is inclined upward.

[0008] The inclined plate between the second layer of vertical plate and the third layer of vertical plate is inclined downward.

[0009] The upper part of the vertical plate is inclined forward, and the inclination angle is 15°-60°.

[0010] The top plate is fixed with a lifting lug at the top.

[0011] The present application has the following beneficial effects: due to the above-mentioned scheme, the water permeable holes on the surface of the vertical plate can quickly shunt the high-pressure water flow, and then pass through the inclined plate to play a role in pressure reduction, thereby greatly reducing the pressure of the water flow, and the last layer of vertical plate completely blocks the water flow, which can be discharged from below along the drain hole. The anti-impact protection device has good anti-impact performance and can avoid harm to the operator caused by the high-pressure water column or wellhead structure. BRIEF DESCRIPTION OF DRAWINGS

[0015] The application will be further described below with reference to the accompanying drawings:

[0016] As shown in Figure 1 , Figure 2 , an impact protection device includes a top plate 1, a bottom plate 5, at least two vertical plates 2 connected between the top plate 1 and the bottom plate 5, the vertical plates 2 are parallel to each other and have gaps, a plurality of water permeable holes 4 are opened on each vertical plate 2 except the last side vertical plate 2, the water permeable holes 4 on the adjacent two layers of vertical plates 2 are staggered in the horizontal direction, and a plurality of inclined plates 3 are connected between the adjacent vertical plates 2, the inclined plates 3 are located behind the water permeable holes 4, and the width of the inclined plate 3 is not less than the width of the water permeable hole 4. The upper part of the vertical plate 2 is inclined forward, and the inclination angle is 15°-60°, so that the ejected water can be better blocked during use. The top plate 1 is fixed with a lifting lug 6 at the top, and a plurality of drainage holes are opened on the bottom plate 5 to drain the water inside.

[0017] As a preferred, the vertical plate 2 is three layers, for the convenience of description, the side vertical plate facing the water during use is called the first layer vertical plate 2-1, the water permeable holes 4 are opened on the first layer vertical plate 2-1 and the second layer vertical plate 2-2, and the third layer vertical plate 2-3 is a light plate. The inclined plate 3 between the first layer vertical plate 2-1 and the second layer vertical plate 2-2 is inclined upward; the inclined plate 3 between the second layer vertical plate 2-2 and the third layer vertical plate 2-3 is inclined downward. The first layer vertical plate 2-1 is sprayed with enhanced paint, which has the effects of impact resistance, corrosion resistance and wear resistance, can greatly prolong the service life of the metal structural part, and improve the overall impact resistance of the device.

[0018] When the vertical plate facing the water is impacted by high-pressure water flow, the water permeable holes 4 on the surface of the first layer vertical plate 2-1 can quickly shunt the high-pressure water flow, and the water flow that does not pass through flows down along the first layer vertical plate 2-1, the water flow that passes through the water permeable holes 4 impacts on the inclined plate 3, and the inclined plate 3 plays a role in reducing water pressure. A part of the water flow that passes through the water permeable holes 4 on the second layer vertical plate 2-2 continues to shunt, and the part that does not pass through flows down along the second layer vertical plate 2-2, until the third layer vertical plate 3-3 completely shunts the high-pressure water flow.
