Technical Field

[0001] The utility model belongs to the technical field of oil drilling, in particular to a wind and sand filtering and ventilation device for drilling rig network power equipment. Background Art

[0002] Drilling rig power grid equipment is a kind of power grid equipment that provides power conversion during oil drilling operations. It is an advanced technology with broad application prospects and development potential. It can provide green power for drilling operations, has the characteristics of cost saving, convenient maintenance and management, and has high reliability and safety. Drilling rig power grid equipment will become a commonly used drilling operation equipment that provides green power and effectively saves drilling costs during oil drilling operations, and will continue to integrate new technologies and new materials to meet the growing energy demand. When drilling rig power grid equipment is used in areas with harsh environmental conditions such as deserts during oil drilling operations, measures to prevent wind and sand and heat dissipation are particularly important.

[0003] At present, there are some common problems with wind and sand filtering ventilation devices: insufficient wind and sand protection capabilities, cannot be used in deserts and other windy and sandy areas, and wind and sand entering the equipment affect the heat dissipation of the equipment. Therefore, how to improve the wind and sand protection capabilities of existing ventilation devices and ensure normal heat dissipation of the equipment is the problem that this application needs to solve. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a wind and sand filtering ventilation device for drilling rig power equipment, which solves the problem that the existing ventilation device has insufficient wind and sand protection ability and cannot be used in areas with strong wind and sand such as deserts, and the wind and sand enter the equipment and affect the heat dissipation of the equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind and sand filtering and ventilation device for drilling rig power grid equipment, comprising an upper frame and a lower frame, a U-shaped window is installed between the upper frame and the lower frame, the U-shaped window comprises a first U-shaped bar arranged on a plurality of front sides of an outer layer and a second U-shaped bar arranged on a plurality of reverse sides of an inner layer, two adjacent first U-shaped bars and two second U-shaped bars are symmetrically arranged and cross-arranged, a plurality of quicksand bars are installed on the lower frame, and the quicksand bars are located between two adjacent first U-shaped bars and the second U-shaped bar.

[0006] As a further solution of the utility model: the upper frame and the lower frame are of Z-shaped design, and the upper frame and the lower frame are symmetrically arranged with respect to the middle of the U-shaped window.

[0007] As a further solution of the utility model: the first U-shaped strip and the second U-shaped strip are cross-arranged to form a meander-shaped air duct.

[0008] As a further solution of the utility model: the quicksand bars are of Z-shaped design, and protective baffle bars are installed on a plurality of quicksand bars.

[0009] As a further solution of the utility model: the protective baffle is connected to the first U-shaped bar and the second U-shaped bar, and the protective baffle is L-shaped.

[0010] Compared with the prior art, the beneficial effect of the utility model lies in: by symmetrically arranging the first U-shaped strip and the second U-shaped strip and cross-arranging them, a meandering air duct is formed, which can reduce the wind speed, so that the dust and stones entrained in the air fall to the Z-shaped quicksand strip at the bottom due to gravity, thereby achieving the purpose of filtering the wind and sand, and the inclined surface in the quicksand strip can play a role in guiding the flow, discharging the dust and stones out of the periphery of the ventilation device, so that the ventilation device effectively prevents the dust from entering the grid power equipment room, and has good ventilation and heat dissipation effects, thereby ensuring the stable operation of the grid power equipment. Compared with the prior art, the use of a filter to filter the dust and stones is abandoned. The ventilation device can directly discharge the blocked dust through the quicksand strip, which will not cause blockage and affect heat dissipation, and at the same time reduce the workload of cleaning the filter.

[0015] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0016] like Figure 1-3 As shown, the utility model provides a technical solution: a wind and sand filtering and ventilation device for drilling rig power grid equipment, comprising an upper frame 1 and a lower frame 2, the upper frame 1 and the lower frame 2 are Z-shaped, the upper frame 1 and the lower frame 2 are symmetrically arranged about the middle of a U-shaped window 3, the upper frame 1 and the lower frame 2 with a Z-shaped design can play a role in supporting and limiting the U-shaped window 3, and can increase the bearing capacity of the U-shaped window 3 on the side that resists wind and sand.

[0017] A U-shaped window 3 is installed between the upper frame 1 and the lower frame 2. The U-shaped window 3 includes a first U-shaped bar 301 arranged on the front side of the outer layer and a second U-shaped bar 302 arranged on the back side of the inner layer. The first U-shaped bar 301 and the second U-shaped bar 302 are arranged crosswise to form a meandering air duct, which can reduce the wind speed and make the dust and stones entrained in the air fall to the Z-shaped quicksand bar 4 at the bottom due to gravity, thereby achieving the purpose of filtering wind and sand.

[0018] The two adjacent first U-shaped bars 301 and the two second U-shaped bars 302 are symmetrically arranged and cross-arranged. A plurality of quicksand bars 4 are installed on the lower frame 2. The quicksand bars 4 are Z-shaped in design. Protective baffles 5 are installed on the plurality of quicksand bars 4. The inclined surfaces in the quicksand bars 4 can play a role in guiding flow, thereby preventing sand and dust from accumulating at the connection between the first U-shaped bar 301 and the two second U-shaped bars 302.

[0019] The quicksand bar 4 is located between two adjacent first U-shaped bars 301 and the second U-shaped bar 302, the protective baffle 5 is connected to the first U-shaped bar 301 and the second U-shaped bar 302, and the protective baffle 5 is L-shaped. The L-shaped protective baffle 5 can cover the connection between the first U-shaped bar 301, the second U-shaped bar 302 and the lower frame 2 to prevent sand and dust from blowing into the connection and affecting the supporting stability of the U-shaped window 3.

[0020] The working principle of the utility model is as follows: when the filtering ventilation device is used to block the wind and sand, the first U-shaped strip 301 and the second U-shaped strip 302 are cross-arranged and form a meandering air duct, which can reduce the wind speed, so that the dust and stones entrained in the air fall to the Z-shaped quicksand strip 4 at the bottom due to gravity, and the wind and sand can be filtered. The inclined surface in the quicksand strip 4 can play a role in guiding the flow. At the same time, the L-shaped protective baffle strip 5 can cover the connection between the first U-shaped strip 301, the second U-shaped strip 302 and the lower frame 2, so as to discharge the dust and stones out of the periphery of the ventilation device.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
