Referring to fig. 1 to 3, the volute assembly according to the embodiment of the first aspect of the present invention includes a first volute 100 and a second volute 200, the first volute 100 and the second volute 200 may be connected by a bolt or a buckle, a wind wheel installation cavity 210 is formed in the second volute 200 and the first volute 100, the wind wheel installation cavity 210 is used for installing a wind wheel 300, a circumferential wall of the wind wheel installation cavity 210 is provided with a positioning portion 211, the positioning portion 211 may be formed on the first volute 100 and/or the second volute 200, the positioning portion 211 may be a section of arc or an annular shape on the circumferential wall, and the positioning portion 211 is suitable for centering of the wind wheel 300 when the wind wheel 300 is installed. Specifically, the position of the positioning portion 211 is the lower side of the edge of the wind wheel 300 when the wind wheel 300 is exactly installed in the wind wheel installation cavity 210 in a centering manner, so that when the wind wheel 300 is installed, the edge of the wind wheel 300 is aligned to the positioning portion 211, and the wind wheel 300 can be installed in the wind wheel installation cavity 210 in a centering manner.
Referring to fig. 2 and 3, the circumferential wall of the wind wheel mounting cavity 210 is provided with the positioning portion 211, so that the wind wheel 300 can be quickly centered and mounted through the positioning portion 211 when the wind wheel 300 is mounted, the centering accuracy of the wind wheel 300 is improved, the phenomena of noise increase and uneven air volume caused by misalignment of the wind wheel 300 are effectively avoided, the quality of after-sale maintenance is improved, and the satisfaction of customers is improved.
Referring to fig. 2, it should be noted that two positioning portions 211 may be provided, and the two positioning portions 211 are respectively disposed at two ends of the circumferential wall of the wind turbine installation cavity 210, that is, the two positioning portions 211 are respectively disposed at regions of the circumferential wall near two ends of the installation cavity 210 in the axial direction. Because the volume of some wind turbines 300 is relatively large, in the installation process of the wind turbines 300, it is difficult for an installer to see both ends of the wind turbine installation cavity 210 at the same time, when the positioning portion 211 is only arranged at one end of the peripheral wall of the wind turbine installation cavity 210, and the head of the installer is close to the other end of the peripheral wall of the wind turbine installation cavity 210, the installer is difficult to see the positioning portion 211 located at the peripheral wall of the wind turbine installation cavity 210, so that it is difficult to position and install the wind turbine 300 through the positioning portion 211. For this reason, in some embodiments of the utility model, location portion 211 is provided with two, and two location portions 211 set up respectively in the both ends of the perisporium of wind wheel installation cavity 210 to make installer's head no matter be close to which end of wind wheel installation cavity 210, all can see the location portion 211 that is located on the perisporium of wind wheel installation cavity 210, thereby can realize the quick centering installation of wind wheel 300, improve the convenience of installation.
It can be understood that, in the actual installation of the wind wheel 300, there is a certain installation error, within which the wind wheel 300 can still keep normal and stable operation, and therefore, the positioning portion 211 can also have a certain width range. Therefore, through a large number of tests, the applicant finds that the width W of the positioning portion 211 is larger than or equal to 2.5mm and smaller than or equal to 4mm, namely the width of the positioning portion 211 is between 2.5mm and 4mm, the centering installation of the wind wheel 300 can be in a proper installation error range by adjusting the wind wheel 300 to enable the edge of the wind wheel 300 to be aligned to any position of the positioning portion 211 during installation, the wind wheel 300 can still keep normal and stable work, and the phenomena of obvious noise increase and uneven air volume are avoided. Therefore, in some embodiments of the present invention, the width of the positioning portion 211 is set to W, and W satisfies the following relationship: w is more than or equal to 2.5mm and less than or equal to 4 mm.
Referring to fig. 4 to 15, in some embodiments of the present invention, the positioning portion 211 is a groove or a rib. The grooves and the ribs are structural features which are more obvious than those of the circumferential wall of the wind wheel mounting cavity 210, so that the grooves or the ribs are aligned with the edges of the wind wheel 300 to position in the mounting process of the wind wheel 300 by an installer, and the wind wheel 300 is centered and mounted. Moreover, the first volute 100 and the second volute 200 are usually made of plastic or metal plates, so that it is more convenient to form grooves or ribs in the wind wheel mounting cavity 210 during the forming process, and the processing convenience is improved. Of course, the positioning portion 211 specifically adopts a groove or a rib structure, and a user can specifically select the positioning portion according to actual needs.
Referring to fig. 4 to 9, in some embodiments of the present invention, the positioning portion 211 is configured as a groove, the cross section of the groove may be a triangle, a square, a trapezoid, a semicircle, an ellipse, or another shape, and the user may specifically select a suitable cross section shape to configure according to actual needs.
It can be understood that when the depth of the groove is shallow, it is not significant enough on the circumferential wall of the wind turbine installation cavity 210, which affects the centering installation operation of the wind turbine 300, whereas when the depth of the groove is deep, the machining is difficult, and the manufacturing cost is increased. For this reason, the applicant has made extensive experiments and found that the depth H1 of the groove satisfies the following relationship: h1 is not less than 1mm and not more than 2mm, when the degree of depth of recess is between 1mm to 2mm promptly, the processing degree of difficulty of recess is not high this moment, and the recess is more obvious on the perisporium of wind wheel installation cavity 210 this moment, installer can observe the edge of recess and recess very easily, thereby in the installation of wind wheel 300, can be convenient aim at the recess with the edge of wind wheel 300 and fix a position fast, thereby realize the quick centering installation of wind wheel 300, the convenience of operation is improved. Thus, in some embodiments of the present invention, the depth of the groove is H1, and H1 satisfies the following relationship: h1 is more than or equal to 1mm and less than or equal to 2 mm.
Referring to fig. 10 to 15, in other embodiments of the present invention, the positioning portion 211 is configured as a rib, the cross section of the rib may be square, trapezoid, semicircle, ellipse, or other shapes, and the user may specifically select a suitable cross section shape to configure according to actual needs.
It can be understood that when the height of the rib is lower, the rib is not obvious enough on the peripheral wall of the wind wheel mounting cavity 210, which affects the centering mounting operation of the wind wheel 300, however, when the height of the rib is higher, the rib uses more material, and the processing is difficult, and the manufacturing cost is high. For this reason, the applicant has conducted a great deal of experiments and found that the height H2 of the bead satisfies the following relationship: h2 is not more than 1mm and not more than 2mm, the height of protruding muscle is between 1mm to 2mm promptly, the cost of manufacture of protruding muscle this moment is not high, and protruding muscle this moment is more obvious on the perisporium of wind wheel installation cavity 210, installer can observe the edge of protruding muscle and protruding muscle very easily, thereby in the installation of wind wheel 300, can be convenient aim at protruding muscle with the edge of wind wheel 300 and advance line location fast, thereby realize the quick centering installation of wind wheel 300, the convenience of operation is improved. Thus, in some embodiments of the present invention, the depth of the bead is H2, and H2 satisfies the following relationship: h2 is more than or equal to 1mm and less than or equal to 2 mm.
