Technical Field

[0001] This invention relates to the technical field of wind turbine structures, and in particular to a wind turbine structure and its installation method. Background Technology

[0002] Gas water heaters are usually equipped with a fan to exhaust the waste gas and residual heat generated during the use of the water heater, thereby reducing the impact of waste gas and residual heat on the normal operation of the water heater.

[0003] Chinese invention patent CN113758018B discloses a fan device and a water heater, the casing of which is adapted to the fan. Water heaters generate a large amount of waste heat during operation. To meet the needs of the water heater, the casing is usually made of metal. However, due to the irregular shape of the casing itself, it is currently assembled using sheet metal processing. This involves stamping multiple sheet metal parts and then riveting or welding them together to complete the overall assembly of the casing. The required sheet metal parts come in many specifications, and the actual assembly process involves connecting multiple sheet metal parts one by one, making the processing steps quite cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a wind turbine structure and installation method to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0005] The solution to the technical problem of this invention is:

[0006] A fan structure has mutually orthogonal front-back, left-right, and up-down directions, including a housing. The housing is made of a high-temperature resistant material. The housing has an interconnected mounting cavity and an air duct cavity. An air inlet is provided on the housing at a position corresponding to the air duct cavity, and an air outlet is provided on the housing at a position corresponding to the mounting cavity. The housing includes a first outer shell and a second outer shell that are interconnected.

[0007] The shell is made of high-temperature resistant material and can be installed in the special environment of the water heater. During production, the first and second shells can be injection molded and die-cast separately. After molding, the first and second shells are connected together to form the shell. That is, the original multiple sheet metal parts are simplified into two parts to form the shell, which simplifies the process and reduces the processing cost.

[0008] As a further improvement to the above technical solution, the material of the shell is specifically BMC material.

[0009] The BMC is a kind of semi-dry process for manufacturing glass fiber reinforced thermosetting product molding intermediate material, which can be molded and injection molded, and its heat resistance is better than that of general engineering plastics, and its heat distortion temperature HDT is 200-280 DEG C, so the shell made of BMC material will not melt when installed in a water heater.

[0010] As a further improvement of the above technical solution, the material of the shell is specifically a die-casting metal material.

[0011] The metal material can be formed into a corresponding first shell and second shell by die casting, and the metal material is resistant to high temperature.

[0012] As a further improvement of the above technical solution, one of the first shell and the second shell is provided with a sealing block, and the other is provided with a sealing groove, and the sealing block is inserted into the sealing groove.

[0013] The shell itself has the effect of guiding wind, so it has certain requirements for sealing, and the sealing block and the sealing groove are added, the sealing block is inserted into the sealing groove, the area of the first shell and the second shell is increased, and the connection stability of the first shell and the second shell is enhanced, so that the sealing effect of the connection of the first shell and the second shell is better; in addition, the sealing block inserted into the sealing groove plays a guiding effect, so as to facilitate the connection of the first shell and the second shell.

[0014] As a further improvement of the above technical solution, the first shell and the second shell are connected by a connecting piece.

[0015] The connecting piece is added to the first shell and the second shell, so that the connection of the first shell and the second shell is more stable, the connection stability of the first shell and the second shell is enhanced, and the sealing effect of the connection of the first shell and the second shell is better.

[0016] As a further improvement of the above technical solution, the first shell is provided with a first extension plate, the second shell is provided with a second extension plate, and the connecting piece is connected to the first extension plate and the second extension plate.

[0017] The first extension plate and the second extension plate provide a connection position for the connecting piece, so as to facilitate the insertion of the connecting piece into the first extension plate and the second extension plate.

[0018] As a further improvement of the above technical solution, one end of the connecting piece abuts against the outer side wall of the second extension plate, the other end of the connecting piece is rotatably connected with a locking rod, and a torsional spring limiting the angle formed by the connecting piece and the locking rod is connected between the connecting piece and the locking rod.

[0019] Before the connecting piece is threaded through the first extension plate and the second extension plate, the locking rod is first rotated to overcome the elastic force of the torsion spring, so that the locking rod and the connecting piece are coaxially arranged, then the locking rod and the connecting piece are synchronously threaded through the first extension plate and the second extension plate, then the locking rod is released, and the locking rod will form a certain angle with the connecting piece under the action of the torsion spring, thereby reducing the situation that the connecting piece is accidentally detached from the first extension plate and the second extension plate, and the connection stability between the first shell and the second shell can be improved.

[0020] As a further improvement of the above technical solution, the first shell and the second shell are connected by gluing.

[0021] The first shell and the second shell can be connected by gluing, and the above connection method is relatively simple and convenient to operate.

[0022] As a further improvement of the above technical solution, the mounting plate is connected between the mounting cavity and the air duct cavity in the shell body, and the air guide hole is formed in the mounting plate, and the mounting cavity and the air duct cavity are communicated through the air guide hole.

[0023] The mounting plate is mounted in the shell body, the fan can be mounted on the mounting plate, and the mounting cavity and the air duct cavity are communicated through the air guide hole, so that the residual heat enters the mounting cavity from the air duct cavity through the air guide hole.

[0024] The application also provides a mounting method of the fan structure, which comprises the following steps:

[0025] Step a: splicing the first shell and the second shell to form a shell body;

[0026] Step b: locking the first shell and the second shell through the connecting piece.

[0027] The first shell and the second shell after forming are connected together to form a shell body, that is, the original multiple sheet metals are simplified to two components to form a shell body, thereby simplifying the process flow and reducing the processing cost.
