Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to a device for fixing and installing heat pump fans, which is applicable to the ventilation and heat dissipation systems of various air source heat pumps, chillers and other equipment. Background Technology

[0002] The fan is a key component in a heat pump system for achieving forced convection and enhancing heat exchange. The reliability and convenience of its installation and fixing method directly affect the overall performance and maintenance efficiency. Currently, most common heat pump fan installation methods involve directly fastening the fan to the mounting frame with bolts. This method has significant drawbacks: installation requires multiple people to align the holes, making the operation cumbersome and time-consuming; regular maintenance or repair requires disassembling a large number of bolts, resulting in high workload, low efficiency, and repeated disassembly and assembly can easily damage the threads, reducing connection reliability; heavy-duty fan covers lack effective support when opened, posing a safety risk; while some electric push rod opening mechanisms reduce operational intensity, they are costly, structurally complex, and have poor environmental adaptability.

[0003] Therefore, there is an urgent need to propose a heat pump fan fixing device that is structurally reasonable, easy to operate, convenient to install, and easy to maintain. Utility Model Content

[0004] The purpose of this utility model is to provide a heat pump fan fixing device to solve the problems of cumbersome operation, inconvenient maintenance, and safety hazards in the existing fan installation methods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heat pump fan mounting device includes a fan, a base, a mounting frame, and a hydraulic rod. The mounting frame has one or more square mounting holes. The base is shaped to match the mounting holes, and one side of the base is pivotally connected to the corresponding edge of the mounting hole via a hinge, allowing the base to rotate around the hinge axis to cover or open the mounting hole. The fan is fixedly mounted in the center of the base. The first end of the hydraulic rod is pivotally connected to the side of the base, and the second end is pivotally fixed to another edge of the mounting hole opposite the hinge edge, with the hydraulic rod perpendicular to the edge of the mounting hole.

[0007] Furthermore, the first end of the hydraulic rod is connected to the inner side of the base. When the base is closed, the hydraulic rod is completely hidden under the inner side of the base, resulting in a compact overall structure.

[0008] Furthermore, it also includes a spring fitted onto the hydraulic rod, with the spring positioned near the second end of the hydraulic rod to provide cushioning during the closing of the base, enabling the fan cover to fall slowly and smoothly.

[0009] Furthermore, two hydraulic rods are symmetrically arranged on both sides of the base to ensure balance and stability during the lifting process.

[0010] Furthermore, when the hydraulic rod is fully extended, the angle between it and the base is 75°, which is suitable for ventilation and maintenance, and makes operation easier and positioning more stable.

[0011] Furthermore, it also includes a handle located on the top surface of the base away from the hinge, for assisting in manual opening and closing operations and providing an emergency operation method in case of hydraulic system failure.

[0012] Furthermore, the hinge is a continuous long hinge or a segmented hinge, ensuring that the base rotates smoothly and bears load reliably.

[0013] This utility model has the following beneficial effects:

[0014] 1. Simple and labor-saving operation: With the help of hydraulic rods and buffer design, the fan cover can be opened smoothly and closed slowly, which can be operated by a single person, greatly reducing labor intensity.

[0015] 2. High maintenance efficiency: Eliminates the traditional bolt disassembly and assembly steps, enabling quick opening and locking, and significantly shortening maintenance and repair time.

[0016] 3. High safety: The combination of hydraulic rods and springs provides reliable support and cushioning, avoiding impact and damage caused by sudden opening and closing of the cover plate, and reducing operational risks.

[0017] 4. Compact and reliable structure: The built-in hydraulic rod design saves space, and the overall structure is robust, making it suitable for various heat pump equipment installation environments.

[0018] 5. Cost-effective: Compared with complex mechanisms such as electric actuators, this device has a simple structure, low manufacturing cost, good durability, and low maintenance requirements.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] In the diagram: 10, fan; 20, base; 30, mounting frame; 40, hydraulic rod; 50, spring; 60, handle. Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, the heat pump fan mounting device in this embodiment mainly includes a fan 10, a base 20, a mounting frame 30, hydraulic rods 40, springs 50, and a handle 60. The mounting frame 30 is fixed to the corresponding position of the heat pump unit and has square mounting holes. The base 20 matches the size of the mounting holes, and one side is connected to the edge of the mounting holes via a hinge. The fan 10 is fixed to the center of the base 20 with bolts. Two hydraulic rods 40 are symmetrically mounted on both sides of the base 20, one end of which is hinged to the inner side of the base 20, and the other end is hinged to the edge of the mounting hole away from the hinge. Springs 50 are fitted onto the hydraulic rods 40 to buffer the closing action. The handle 60 is mounted on the top surface of the base 20 away from the hinge.

[0025] During operation, lift the handle 60 upwards, and the hydraulic rod 40 will gradually extend, smoothly lifting the base 20 and the fan 10 to the maximum opening angle of 75°, after which the base 20 remains constant. After maintenance is completed, gently press the handle 60 downwards, and the hydraulic rod 40 and the spring 50 will work together to make the base 20 close slowly and smoothly.

[0026] This utility model adopts a hydraulic rod structure, which can complete the 75° lifting action of the 30kg cover plate within 30 seconds, and complete the fan opening action, ensuring the opening and closing stability under various temperature environments.

[0027] The above embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Modifications, equivalent substitutions, or improvements made by those skilled in the art within the scope of this utility model should be included within the scope of protection of this utility model.
