Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and more specifically, it relates to a flow guiding device for an air conditioner unit in a vaccine workshop. Background Art

[0002] In the air conditioning system of a vaccine factory, in some air conditioning systems, due to the eddy current generated between the return air flow and the fan, the pressure of the return air duct is extremely unstable, which easily causes the return air duct to vibrate, and then drives the entire unit to vibrate. In order to better guide the air flow into the fan to avoid the vibration of the unit, it is necessary to weld a large-volume air guiding part at the air inlet hole of the fan.

[0003] However, during the welding process of the air guiding part, it is necessary for multiple workers to hold the air guiding part by hand to position and stabilize it. Due to the long-term hand-holding, the workers will feel fatigued, resulting in the air guiding part deviating from the predetermined position, so it is necessary to re-weld, which reduces the installation efficiency of the air guiding part.

[0023] Please refer to Figures 1 to 5 , and now the flow guiding device for the air-conditioning unit of the vaccine workshop provided by the present utility model will be described.

[0026] The inner bottom wall of the air hood 2 is the inner side wall away from the open end of the air hood 2.

[0027] In the embodiment of the present application, a diversion device for a vaccine workshop air conditioning unit is provided. During its actual use, one end of the connecting rod 21 is connected to the outer peripheral wall of the positioning sleeve 20 and extends outward to be connected to the inner peripheral wall of the air inlet hole 4, thereby fixing the position of the positioning sleeve 20. The required length of the positioning sleeve 20 is determined according to the actual situation. When installing the diversion pipe 10, first align the positioning strip 31 with the positioning groove 22, align the socket 30 with the positioning sleeve 20, and insert the socket 30 into the positioning sleeve 20.

[0028] During disassembly, only need to rotate and separate the locking sleeve 40 from the positioning sleeve 20 and pull the diversion pipe 10 downward at the lower end of the positioning sleeve 20, then the diversion pipe 10 can be disassembled, thus quickly disassembling the diversion pipe 10 and improving the disassembly efficiency.

[0029] Compared with the prior art, for the diversion device for a vaccine workshop air conditioning unit provided in this embodiment, when installing the diversion pipe 10, first align the positioning strip 31 with the positioning groove 22, align the socket 30 with the positioning sleeve 20, and insert the socket 30 into the positioning sleeve 20. Then, sleeved the locking sleeve 40 on the outer periphery of the positioning sleeve 20 and rotate the locking sleeve 40 to axially push the positioning strip 31 along the positioning sleeve 20 until the positioning strip 31 abuts against the bottom wall of the positioning groove 22. Through the plug-in positioning of the socket 30 and the positioning sleeve 20 and the cooperation of the locking sleeve 40 to lock the axial position of the socket 30, it is not necessary for manual long-term holding of the diversion pipe 10, and the relative position of the diversion pipe 10 and the fan 1 can be quickly fixed, improving the installation efficiency of the diversion pipe 10.

[0030] In a possible implementation manner, the above-mentioned connecting rod 21 adopts the structure as Figures 3 to 5 shown, see Figures 3 to 5 , and a plurality of connecting rods 21 are arranged at intervals in the circumferential direction of the positioning sleeve 20.

[0031] Specifically, the arrangement of multiple connecting rods 21 can strengthen the fixing of the position of the positioning sleeve 20 and improve the connection strength between the positioning sleeve 20 and the air inlet hole 4.

[0032] In a possible implementation, the above-mentioned positioning groove 22 adopts the structure as shown in Figures 3 to 5 . Refer to Figures 3 to 5 .

There are two positioning bars 31, and they are arranged in one-to-one correspondence with the two positioning grooves 22.

[0033] Specifically, through the sliding fit between the positioning bar 31 and the positioning groove 22, the insertion sleeve 30 can stably slide along the axial direction of the positioning sleeve 20, avoiding the relative rotation between the insertion sleeve 30 and the positioning sleeve 20, ensuring the stability of the fixed position of the diversion pipe 10, and the setting method of the two positioning grooves 22 and the two positioning bars 31 can further enhance the positioning effect between the insertion sleeve 30 and the positioning sleeve 20.

[0034] In some embodiments, refer to Figures 3 to 5 . A force-applying rod 41 extending outward is connected to the outer peripheral wall of the locking sleeve 40.

Without manually holding the diversion pipe 10, welding can be directly carried out, avoiding the diversion pipe 10 from deviating from the predetermined position, improving the welding efficiency, and further strengthening.

[0040] Furthermore, as shown in Figure 1 and Figure 2 , the axial length of the diversion pipe 10 is 1000 mm, the distance between the diversion pipe 10 and the inner bottom wall of the wind hood 2 is 450 mm, the outer diameter of the diversion pipe 10 is 1400 mm, and the inner diameter of the diversion pipe 10 is 1250 mm.

[0041] Furthermore, this installation method of the diversion pipe 10 can buffer the air flow entering the air hood 2, enable it to stably enter the diversion pipe 10, and is the optimal specification selected through a large number of CFD simulations and practices, avoiding the vibration of the unit. Moreover, the connecting rod 21 and the positioning strip 31 can also shunt and buffer the air flow, further improving the stability of the unit.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
