Description

Shipborne noise reduction fan Technical Field

[0001] This application relates to the field of wind turbine technology, and more specifically, to a shipborne noise-reducing wind turbine. Background Technology

[0002] Marine fans are a type of special ventilation equipment designed specifically for the shipboard environment. They are mainly used for air circulation, equipment cooling, and cabin environment regulation within the ship. Their core function is to ensure air circulation in the ship's confined spaces while meeting the special requirements of the ship's harsh operating conditions.

[0003] The existing protective frame is usually fixed to the fan casing with multiple bolts. When internal maintenance is required, the bolts need to be loosened one by one to remove the protective frame for internal maintenance, which is quite troublesome.

[0004] Therefore, a shipborne noise-reducing fan with easy disassembly is provided. Summary of the Invention

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below.

After releasing the drive shaft, the limit block will move from the limit groove to the receiving groove under the action of the first spring, so that one end of the protective frame can be separated from the limit block, thereby opening the protective frame for internal maintenance. Compared with traditional bolt fixing, it is easier to disassemble.

[0008] Furthermore, the limiting groove is used to limit the movement of the limiting block.

[0009] Furthermore, the insertion slot is for the insertion of a limiting block.

[0010] Furthermore, the connecting block is provided with a first groove along the width direction of the connecting block; the first sliding plate moves along the first groove.

[0011] Furthermore, the connecting block includes a first cavity; the first spring is located within the first cavity.

[0012] Furthermore, the fixing block includes a first guide hole; the connecting block includes a second guide hole; and the drive shaft portion is located within the second guide hole.

[0013] Furthermore, the limiting groove and the insertion groove extend along the axial direction of the first guide hole.

[0014] Furthermore, the connecting groove extends along the circumferential direction of the second guide hole.

[0015] Furthermore, the fixing component also includes a push plate, which is fixedly connected to the drive shaft.

[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Referring to Figures 1-7, a shipboard noise-reducing fan 100 includes: a fan housing 101, a protective frame 102, a fixing block 103, a connecting block 104, and a fixing assembly for fixing one end of the protective frame 102 to the fan housing 101. One end of the protective frame 102 is rotatably connected to the fan housing 101, and the other end is fixed to the fan housing 101 via the fixing assembly. Specifically, the fan housing 101 includes an L-shaped block, and the protective frame 102 includes a connecting plate, which is rotatably connected to the L-shaped block. The L-shaped block includes a clearance groove, and the clearance groove is spaced apart from the connecting plate to facilitate the rotation of the connecting plate.

[0036] The fixing block 103 is fixedly connected to the fan housing 101. The connecting block 104 is fixedly connected to the protective frame 102. The fan housing 101 includes a fixing frame 113, a motor 114, and a fan blade 115. The fixing frame 113 is fixedly connected to the fan housing 101. The motor 114 is fixedly connected to the fan housing 101, and the fan blade 115 is fixed to the output shaft of the motor 114. The motor 114 is a permanent magnet synchronous motor. The permanent magnet synchronous motor has better noise control than the traditional motor 114, and sound-absorbing cotton is also provided on the inner wall of the fan housing 101 to further improve the quietness during use.

[0037] The fixing assembly, used to fix one end of the protective frame 102 to the fan housing 101, includes: a drive shaft 105, a limiting block 106, a first sliding plate 107, a first spring 108, a push plate 109, a first limiting plate 110, and a second limiting plate 112. The drive shaft 105 is inserted into the connecting block 104. The limiting block 106 is fixedly connected to the drive shaft 105. The inner side of the first sliding plate 107 is rotatably connected to the drive shaft 105. Specifically, the drive shaft 105 includes a guide groove, and part of the first sliding plate 107 is located in the guide groove, rotating around the circumference of the drive shaft 105.

[0038] The outer side of the first sliding plate 107 is horizontally slidably connected to the connecting block 104. Specifically, the connecting block 104 has a first sliding groove 104a along the width direction of the connecting block 104, and the first sliding plate 107 moves along the first sliding groove 104a. The two ends of the first spring 108 are fixedly connected to the first sliding plate 107 and the connecting block 104, respectively. The push plate 109 is fixedly connected to the drive shaft 105. The first limiting plate 110 is fixedly connected to the connecting block 104. The second limiting plate 112 is fixedly connected to the connecting block 104.

[0039] The fixing block 103 includes a limiting groove 103a, a connecting groove 103b, and an insertion groove 103c. The limiting groove 103a is used to limit the positioning of the fixing block 106, and the insertion groove 103c is for the insertion of the fixing block 106. The limiting groove 103a communicates with the connecting groove 103b, and the connecting groove 103b communicates with the insertion groove 103c. The connecting block 104 includes a receiving groove 104b. The fixing block 103 includes a first guide hole 103d, and the connecting block 104 includes a second guide hole 104c. The drive shaft 105 is partially located in the second guide hole 104c and can move along the axial direction of the second guide hole 104c while rotating about the axial direction of the second guide hole 104c. The first guide hole 103d and the second guide hole 104c are located in the same axial direction.

[0040] When one end of the connecting block 104 abuts against the fixing block 103, the receiving groove 104b communicates with the insertion groove 103c, and the first guide hole and the second guide hole 104c are located on the same axis. The limiting groove 103a and the insertion groove 103c extend along the axial direction of the first guide hole. The connecting groove 103b extends along the circumferential direction of the second guide hole 104c. The connecting block 104 includes a first cavity 104d, and the first spring 108 is located in the first cavity 104d. When internal maintenance is required, push the push plate 109. The movement of the push plate 109 drives the drive shaft 105 to move. The movement of the drive shaft 105 causes the limiting block 106 to move from the limiting groove 103a to the connecting groove 103b. Then, rotate the push plate 109 to rotate the limiting block 106 from the connecting groove 103b to the insertion groove 103c. Then, release the push plate 109. Under the action of the first spring 108, the limiting block 106 will move from the insertion groove 103c to the receiving groove 104b, which will separate one end of the protective frame 102 from the fan housing 101. By rotating the protective frame 102, the inside of the fan housing 101 can be maintained. Compared with traditional bolt fixing, it is easier to disassemble, thus facilitating internal maintenance.

[0041] Workflow: When internal maintenance is required, push plate 109 is pushed, causing drive shaft 105 to move. Drive shaft 105 moves limit block 106 from limit groove 103a to connecting groove 103b. Then, push plate 109 is rotated, moving from first limit plate 110 to second limit plate 112, causing limit block 106 to rotate from connecting groove 103b to insertion groove 103c. Then, push plate 109 is released. Under the action of first spring 108, limit block 106 moves from insertion groove 103c to receiving groove 104b, allowing one end of protective frame 102 to separate from fan housing 101. Rotating protective frame 102 allows for internal maintenance of fan housing 101. Compared with traditional bolt fixing, this method is easier to disassemble, facilitating internal maintenance. Motor 114 drives fan blade 115 to rotate, thereby ventilating the air inside the ship and ensuring air circulation in the ship's enclosed space.
