Description

Technical Field

[0001] This utility model relates to the field of wind turbine support technology, specifically to a wind turbine intermediate support and a ceiling machine. Background Technology

[0002] In air conditioning, ventilation equipment, and other duct systems, the dual-impeller structure is widely used due to its ability to provide larger air volume and more stable airflow. This type of dual-impeller structure typically requires an intermediate impeller support to reliably connect and support the two side-by-side impellers, ensuring their synchronous and stable operation. Existing intermediate impeller supports often have complex structural designs, typically using multiple independent fasteners, such as screws or bolts, to fix the various components of the support. This fixing method has significant drawbacks: firstly, the assembly process is cumbersome, requiring the alignment and tightening of multiple screws one by one, resulting in low production efficiency; secondly, under long-term vibration loads, the screws may loosen, affecting the reliability of the connection and even generating noise; furthermore, the excessive number of fasteners increases material and management costs. Therefore, a simplified, convenient, and reliable intermediate impeller support is needed to overcome the various shortcomings of existing technologies caused by complex and inconvenient fixing methods. Utility Model Content

[0003] Therefore, this utility model embodiment provides a wind turbine intermediate support and ceiling machine, making the support fixing more convenient and quick.

[0004] To solve the above problems, this utility model provides a wind turbine intermediate support. The wind turbine intermediate support is disposed on a base plate and is used to connect two wind turbines. The wind turbine intermediate support includes: a first housing connected to the base plate; a second housing with a rotating cover disposed on the first housing; the first housing is provided with a first positioning part; the second housing is provided with a second positioning part, and the first positioning part and the second positioning part are embedded and cooperated to fix the first housing and the second housing.

[0005] Compared with existing technologies, the technical advantages of this solution are as follows: By designing the wind turbine's intermediate support as a first and second rotatable housing, with a first positioning part on the first housing and a second positioning part on the second housing, the housings are fixed through an interlocking fit. This means that simply placing the second housing onto the first housing automatically completes the fitting and fixing, significantly improving assembly efficiency. Simultaneously, the interlocking structure provides mechanical interlocking, ensuring the stability and reliability of the connection between the first and second housings, effectively preventing loosening due to vibration during wind turbine operation, improving the operational stability and service life of the entire wind turbine system, and also helping to reduce the number of parts and lower production costs.

[0006] In one embodiment of this utility model, the wind turbine intermediate support further includes: a second positioning part protruding towards the first positioning part; when the second housing is placed on the first housing, the second positioning part is embedded in the first positioning part.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: The protruding structure design allows the second positioning part to actively and precisely guide and enter the first positioning part during the closing process of the second shell, achieving a function similar to a "positioning pin" and ensuring the unidirectionality and determinism of the assembly action. Through the tight fit between the protrusion and the corresponding part, the shear resistance and overall structural rigidity of the two shells at the joint surface are enhanced, thereby more effectively constraining the relative displacement of the shells and further improving the strength and durability of the connection point when subjected to complex dynamic loads transmitted from the wind turbine.

[0008] In one embodiment of this utility model, the first housing and the second housing are provided with bearing mounting positions, and the wind turbine intermediate support further includes: two second positioning parts and two first positioning parts, and the two first positioning parts and the two second positioning parts are respectively arranged on both sides of the bearing mounting positions.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: By setting two first positioning parts and two second positioning parts on both sides of the bearing mounting position, the force can be evenly distributed to the positioning structure on both sides of the support when fixed, avoiding stress concentration, improving the support stability of the support for the wind turbine, ensuring that the wind turbine shaft center is always kept in the precise design position, effectively suppressing possible swaying or vibration of the wind turbine, and thus ensuring the smooth operation of the dual wind turbine system.

[0010] In one embodiment of this utility model, the wind turbine intermediate support further includes: one of the two first positioning parts is shaped like a waist hole, and the other is shaped like a non-waist hole.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the elongated oval structure of the waist hole provides an allowable displacement in a specific direction, so that when the first shell and the second shell are rotated and covered, the second positioning part can achieve a small displacement in the waist hole, thereby allowing the second positioning part to enter the first positioning part more smoothly, making the assembly between the first shell and the second shell simpler and faster.

[0012] In one embodiment of this utility model, the wind turbine intermediate support further includes: at least one of the two second positioning parts is provided with a guide cut surface, and the second positioning part with the guide cut surface is embedded and engaged with the first positioning part that is not a waist hole.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the guide cut surface forms an inclined guide surface. When the second housing is closed, this cut surface can contact the first positioning part before the main body of the positioning part, and gradually convert the vertical closing force into a horizontal guiding force, thereby smoothly guiding the second positioning part to slide into and accurately fall into the first positioning part. This makes the entire assembly process smoother and less labor-intensive, avoids jamming or impact damage that may occur due to misalignment, and further improves the convenience of assembly and user experience.

[0014] In one embodiment of this utility model, the wind turbine intermediate support further includes: a second housing having a first surface; and one side of the guide section contacting the first surface.

[0015] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting one side of the guide cut surface to contact the first surface, the second positioning part can slide directly into the first positioning part when it contacts the first positioning part, and the cut surface can achieve smoother rotation and closing, reducing the occurrence of collisions, thus making the overall installation more convenient and faster.

[0016] In one embodiment of this utility model, the wind turbine intermediate support further includes: a first limiting part disposed on the first housing; and a second limiting part disposed on the second housing, wherein the first limiting part and the second limiting part abut against each other when the first housing and the second housing are connected.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: This design provides a clear termination position and additional support for the closing action of the housing. When the housing is closed in place, the abutment of the limiting part can effectively prevent damage to the positioning part that may be caused by excessive pressing. At the same time, the abutment setting can also improve the overall sealing performance and avoid mutual interference between the two impellers.

[0018] In one embodiment of this utility model, the wind turbine intermediate support further includes: a second limiting part having a rim protruding toward the first limiting part; and a first limiting part having a recess adapted to the rim.

[0019] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting limiting recesses that fit together with the surrounding edges, the mutual interference of airflow generated during the operation of the left and right wind turbines is avoided, thus preventing the generation of noise.

[0020] In one embodiment of this utility model, the first limiting part and the second limiting part are respectively disposed on both sides of the two wind turbines corresponding to the first housing and the second housing.

[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: by setting the first limiting part and the second limiting part on the corresponding two wind turbine sides, the two limiting parts can better block the airflow generated by the wind turbines on both sides after they come into contact, thereby better reducing the noise generated during operation.

[0022] This utility model also provides a ceiling machine, which includes: a ceiling machine body; and a wind turbine intermediate support as described above, wherein the wind turbine intermediate support is disposed on the ceiling machine body.

[0023] The ceiling-mounted air conditioner in this embodiment includes a ceiling-mounted air conditioner body, and the intermediate support of the impeller is located in the air conditioner body. Therefore, it has all the beneficial effects of the intermediate support of the impeller as in any embodiment of this utility model, which will not be repeated here.

[0024] By adopting the technical solution of this utility model, the following technical effects can be achieved: (1) By designing the wind turbine intermediate support as a first housing and a second housing that can rotate relative to each other, a first positioning part is set on the first housing and a second positioning part is set on the second housing. The housing is fixed by the interlocking fit between the two. Thus, the positioning part can automatically complete the interlocking and fixing by simply covering the second housing with the first housing, which greatly improves the assembly efficiency. At the same time, the interlocking structure provides mechanical interlocking, which ensures the stability and reliability of the connection between the first housing and the second housing, effectively prevents loosening caused by vibration during wind turbine operation, improves the operating stability and service life of the entire wind turbine system, and also helps to reduce the number of parts and reduce production costs. (2) The elongated oval structure of the waist hole provides allowable displacement in a specific direction, so that when the first and second shells are rotated and closed, the second positioning part can achieve a small displacement in the waist hole, thus allowing the second positioning part to enter the first positioning part more smoothly, making the assembly between the first and second shells simpler and faster; the guide surface forms an inclined guide surface, which can contact the first positioning part before the main body of the positioning part when the second shell is closed, and gradually convert the vertical closing force into a horizontal guiding component force, thereby smoothly guiding the second positioning part to slide into and accurately fall into the first positioning part, making the whole assembly process smoother and less labor-intensive, avoiding jamming or impact damage that may occur due to misalignment, and further improving the convenience of assembly and user experience. (3) By setting a limiting recess that fits the edge, the mutual cooperation between the two can avoid the problem of airflow crossing between the left and right wind turbines during operation, thus avoiding noise.
