[0023] In order to further explain the technical methods and effects adopted by the present application to achieve the predetermined application purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in combination with the accompanying drawings and embodiments.
[0024] Please refer to Figures 1 to 5 An embodiment of the present application provides a motor shield 100, which includes a plurality of shield bodies 10 for respectively being mounted on a plurality of power head motors, the plurality of shield bodies 10 being separately arranged from each other, and each shield body 10 including an enclosure 11 for enclosing the corresponding power head motor and a top cover 12 connected to the top edge of the enclosure 11 to cover the power head motor.
[0025] Specifically, in the present embodiment, the cover body 10 is a semi-enclosed structure, and the protection range of the cover body 10 is the free end of the power head motor and the surroundings of the free end.
[0026] Furthermore, a split protection design is adopted for the motor shield 100, so that the motor shield 100 includes multiple independent motor shield bodies 10, and the multiple shield bodies 10 are separately arranged from each other and are respectively arranged on multiple power head motors, thereby avoiding mechanical and electrical failures caused by the power head motor being wrapped by mud, water, sand and gravel when the rotary drilling rig is working, and at the same time avoiding additional alternating loads on the motor shield 100 when the power head is working, thereby extending the service life of the motor shield 100.
[0027] The enclosure 11 includes a first enclosure section 111 enclosing the motor body of the power head motor and a plurality of second enclosure sections 112 for enclosing the terminal sockets of the power head motor. The first enclosure section 111 is a plate bent into an arc shape, and the plurality of second enclosure sections 112 are flat plates and are connected in sequence. The two ends of the first enclosure section 111 are respectively connected to the two second enclosure sections 112.
[0028] Specifically, in the present embodiment, the plurality of second enclosure sections 112 of the enclosure 11 enclose the wire interface of the power head motor inside the cover body 10, so that the wire interface of the power head motor can avoid electrical faults caused by being wrapped by mud, water, sand and gravel.
[0029] It can be understood that the above-mentioned enclosure plate 11 can be a whole plate, or can be formed by assembling multiple enclosure plate segments by welding or other methods.
[0030] The top cover 12 includes a first top plate 121, a second top plate 122, a third top plate 123 and a fourth top plate 124 connected in sequence; the first top plate 121 is a rectangular flat plate, the second top plate 122 is a trapezoidal flat plate, the upper bottom edge of the second top plate 122 is connected to the first top plate 121, and the first top plate 121 and the second top plate 122 are arranged in the same plane; the third top plate 123 is a rectangular flat plate, the fourth top plate 124 is an arcuate flat plate, the fourth top plate 124 is arranged in a plane parallel to the first top plate 121 and the second top plate 122, the third top plate 123 is arranged in a plane perpendicular to the first top plate 121, the second top plate 122 and the fourth top plate 124, and the two opposite side edges of the third top plate 123 are respectively connected to the lower bottom edge of the second top plate 122 and the bottom edge of the fourth top plate 124.
[0031] Specifically, in this embodiment, the radial cross-section of the top cover 12 is roughly stepped, wherein the raised portion is the first top plate 121 and the second top plate 122; the base is the fourth top plate 124; and the third top plate 123 is a rectangular flat plate connecting the raised portion and the base.
[0032] Furthermore, in this embodiment, the top edge of the enclosure 11 is fixedly connected to the edge of the top cover 12, wherein the top edge of the first enclosure section 111 of the enclosure 11 corresponds to the edge of the base of the top cover 12, the top edge of the second enclosure section 112 of the enclosure 11 corresponds to the edge of the raised portion of the top cover 12, and the height of the first enclosure section 111 is less than the height of the second enclosure section 112.
[0033] It is understandable that the top cover 12 can be a whole plate or can be assembled from multiple top plates by welding. The cover body 10 is assembled from the top edge of the enclosure 11 and the edge of the top cover 12 by welding.
[0034] The fourth top plate 124 is provided with a plurality of fixing holes 124A for fixing the top cover 12 to the power head motor.
[0035] Specifically, the plurality of fixing holes 124A are distributed in a ring shape on the top cover 12 , and the angle between the plurality of fixing holes 124A is approximately 62 degrees.
[0036] The motor shield 100 further includes a first buffer member 20 for being sandwiched between the fourth top plate 124 and the motor body of the power head motor. The position of the first buffer member 20 corresponds to the fixing hole 124A.

[0038] Furthermore, the first buffer member 20 is a gasket, and the first buffer member 20 is fixed to the fourth top plate 124 by welding or the like, and is used to enhance the sealing of the cover body 10 and adjust the gap between the cover body 10 and the power head motor.
[0039] The motor shield 100 further includes a second buffer member 30 installed on a side of the first enclosure section 111 adjacent to the main body of the power head motor.
[0040] Specifically, the second buffer member 30 is installed between the first enclosure section 111 and the power head motor body by means of adhesion or the like, and is used to reduce the interaction force between the power head motor body and the first enclosure section 111 when the power head is working.
[0041] The motor shield 100 further includes a mounting and dismounting member 40 mounted on a side of the top cover 12 facing away from the enclosure 11 , and used for mounting and dismounting the shield body 10 .
[0042] Specifically, the loading and unloading member 40 is installed on the enclosure 11 and / or the top cover 12, and the loading and unloading member 40 is a handle that is roughly U-shaped.

The fourth top plate 124 is fixedly connected to the power head motor main body through the mounting holes 51 and the fixing holes 124A, thereby fixing the cover body 10 to the power head motor.
[0045] Specifically, the position of the mounting hole 51 of the mounting bracket 50 corresponds to the fixing hole 124A of the top cover 12, and in the power head motor body, the position of the mounting bracket 50 can be changed, and the position of the mounting hole 51 can also be changed. Since the fixing hole 124A is an opening of the fourth top plate 124, the position of the fixing hole 124A can be changed.
[0046] It can be understood that the position of the mounting hole 51 always corresponds to the position of the fixing hole 124A, and the position of the mounting hole 51 and the position of the fixing hole 124A can be changed based on the position of the other.
[0047] The motor shield 100 further includes a plurality of first buffer members 20 , which are respectively disposed between the plurality of mounting holes 51 and the plurality of fixing holes 124A.
[0048] Specifically, one or more first buffer members 20 are disposed between each mounting hole 51 and the fixing hole 124A, so as to enhance the sealing performance of the cover body 10 and fill the gap between the fourth top plate 124 and the motor body of the power head.
