Description

Technical Field

[0001] This utility model belongs to the field of offshore oil and gas production technology, specifically relating to a motor protective cover for offshore oil and gas platforms. Background Technology

[0002] Offshore oil and gas production facilities are located far from land and have limited space resources, thus requiring extremely high space utilization of equipment. To meet this need, small power equipment (such as chemical pumps and agitator pumps) on offshore oil and gas platforms uses compact, floor-standing vertical motors. Vertical motors are not only easy to install and maintain, but their proper selection and application can also significantly improve equipment performance and operating efficiency, ensuring stable power output and reliable operation of critical equipment.

[0003] Given the continuous nature of offshore oil and gas platform production, which typically cannot be interrupted, backup equipment is generally used for critical equipment to ensure operational stability and reliability. This means that during operation, one piece of equipment (such as a vertical motor) is always idle or stopped, and the downtime is relatively long. Generally, vertical motors, due to their inherent good protection features, do not experience problems when stopped. However, their use on offshore oil and gas platforms presents the following challenges:

[0004] Offshore oil and gas platforms are constructed entirely of welded steel, and their compact spaces mean that if corrosion prevention is not timely, rust can fall from the top. If this rust falls into the vertical motor guard, it can negatively impact the motor.

[0005] Due to the high volume of rainwater at sea, and the mixing of rainwater and seawater, the corrosion of the motor is exacerbated over time. While the motor surface can be protected against corrosion, the protective cover is difficult to remove and its anti-corrosion effect is insufficient, resulting in severe corrosion inside the protective cover.

[0006] Rainwater enters the motor's protective cover directly through the heat dissipation holes on top, causing rainwater to flow down the motor shaft for a long time. Over time, some of the rainwater will accelerate the damage to the motor bearings, and in severe cases, it may even burn out the motor. Summary of the Invention

[0007] The purpose of this utility model is to provide a motor protective cover for offshore oil and gas platforms, which can protect vertical motors on offshore oil and gas platforms, ensuring safety and reliability and extending the service life of vertical motors.

[0008] To achieve the above technical objectives, the present invention adopts the following technical solution: a motor protective cover for an offshore oil and gas platform, characterized in that: it includes a protective cover body and a protective cover, the top surface of the protective cover body is provided with heat dissipation holes evenly distributed, the protective cover is disposed above the heat dissipation holes and is movably connected to the protective cover body through an adjustment component, and the distance between the protective cover and the top surface of the protective cover body can be adjusted by the adjustment component.

[0009] Furthermore, the adjustment assembly includes a fixing ear, an adjustment rod, a positioning screw, and a positioning fastening nut; the fixing ear is connected to the side of the protective cover body, and multiple adjustment holes are spaced apart on the adjustment rod. The fixing ear has a positioning hole. During installation, one of the adjustment holes on the adjustment rod is aligned with the positioning hole on the fixing ear, and the positioning screw passes through the positioning hole and the adjustment hole and is connected to the positioning fastening nut.

[0010] Furthermore, the fixing ear is a limiting tube, which is welded and fixed to the side of the protective cover body; during installation, the adjusting rod passes through the limiting tube and is fixed by the positioning screw and the positioning fastening nut.

[0011] Furthermore, a connecting screw is provided on the upper part of the adjusting rod, and a connecting hole is provided on the protective cover. During installation, the connecting screw passes through the connecting hole and is connected to the connecting fastening nut.

[0012] Furthermore, the connecting screw is welded and fixed to the top surface of the adjusting rod.

[0013] Furthermore, both the main body and the cover of the protective shield are made of 316L stainless steel.

[0014] Furthermore, the adjustment assembly is provided in four sets.

[0015] The beneficial effects of this utility model are: by adopting the above structure, the protective cover body and the protective cover work together to protect the vertical motor, which solves the problem that the vertical motor on the offshore platform is prone to water ingress, while reducing the corrosion of the motor end cover, avoiding the impact of falling objects on the motor cooling fan blades, and extending the service life of the motor.

[0025] Please refer to the following: Figures 1 to 3 The present invention will now describe a motor protective cover for offshore oil and gas platforms.

[0026] like Figure 1As shown, a protective cover for an electric motor on an offshore oil and gas platform includes a main body 100 and a protective cover 200. The main body of the protective cover 100 has evenly distributed heat dissipation holes 101 on its top surface. The protective cover 200 is positioned above the heat dissipation holes 101. The main body of the protective cover 100 and the protective cover 200 are movably connected by an adjusting component 300; in use, the distance between the top surface of the protective cover 200 and the main body of the protective cover 100 can be adjusted according to actual needs using the adjusting component 300.

[0027] Furthermore, the adjustment assembly 300 includes a fixing ear 301, an adjustment rod 302, a positioning screw 303, and a positioning fastening nut 304; the fixing ear 301 is connected to the side of the protective cover body 100, a plurality of adjustment holes 305 are spaced apart on the adjustment rod 302, and a positioning hole 306 is provided on the fixing ear 301.

[0028] Specifically, the fixing ear 301 is a limiting tube, which is welded and fixed to the side of the protective cover body 100. During installation, after the adjusting rod passes through the limiting tube, according to actual needs, one adjusting hole of the adjusting rod 302 is aligned with the positioning hole on the fixing ear 301. After the positioning screw 303 passes through the positioning hole and the adjusting hole, it is connected to the positioning fastening nut 304.

[0029] Additionally, a connecting screw 307 is welded and fixed to the upper part of the adjusting rod 302. The protective cover 200 has a connecting hole 201. During installation, the connecting screw 307 passes through the connecting hole 201 and connects with the connecting fastening nut 308. The protective cover 200 is fixedly connected by the cooperation of the connecting screw 307 and the connecting fastening nut 308. This detachable connection method allows for the replacement of protective covers 200 of different sizes during subsequent production.

[0030] Preferably, both the protective cover body 100 and the protective cover 200 are made of 316L stainless steel, which has the characteristics of high strength, rust resistance and corrosion resistance, and long service life.

[0031] In this embodiment, four sets of adjustment components are provided. The protective cover body 100 and the protective cover 200 are connected by the four sets of adjustment components, resulting in a stable structure.

[0032] When the vertical motor is not in use, lower the adjusting rod 302 to its lowest position so that the protective cover 200 is basically in contact with the protective cover body 100. This effectively prevents rainwater from entering the interior of the protective cover body. When the vertical motor needs to be operated for heat dissipation, raise the adjusting rod 302 and fix it in a suitable position to ensure sufficient heat dissipation space between the protective cover 200 and the protective cover body 100.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
