Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to an adjustable gas volume aquaculture vacuum pump. Background Technology

[0002] In aquaculture, oxygenation of the water body is required, and a vacuum pump is used to pump oxygen into the water.

[0003] Existing vacuum pumps have a fixed impeller speed, and the pump itself does not have the ability to change the pumping volume and pressure. It can only output a specific volume and pressure. Generally, the volume is adjusted by the opening of the valve. When the valve is adjusted, some gas is confined in the pipeline, which leads to an increase in the gas pressure in the pipeline, thereby increasing the power consumption of the equipment. The excess power consumption is dissipated as heat, resulting in excessive heat in the equipment, which affects the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable gas volume vacuum pump for aquaculture, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable air volume aquaculture vacuum pump, comprising: a device body with an air inlet channel, wherein a drive rod and an air inlet assembly are sequentially arranged from the inside to the outside of the air inlet channel, the air inlet assembly includes a bushing and multiple fan blades arranged in a ring array outside the bushing, a turntable is fitted on the bushing, and a connecting rod is rotatably provided between the turntable and the multiple fan blades, wherein when the turntable moves closer to or away from one side of the fan blades, it drives the multiple fan blades to adjust their rotation angle.

[0006] Preferably, the air inlet channel is provided with a moving mechanism connected to the turntable along the axial direction of the drive rod. The moving mechanism is used to drive the turntable to move closer to or away from one side of the fan blade.

[0007] Preferably, the moving mechanism includes a mounting plate, an electric actuator, and a mounting frame connected in sequence. The mounting plate and the mounting frame are respectively installed in the turntable and the air inlet channel, and the electric actuator is installed in the axial direction of the drive rod.

[0008] Preferably, the bushing is fitted with a movable sleeve that is welded to the mounting plate, and the movable sleeve has a rotating groove on the side near the turntable. The turntable is provided with a rotating ring seat that rotates in the rotating groove.

[0009] Preferably, the end of the fan blade facing away from the connecting rod is also provided with a rotating shaft for rotation, and the outer wall of the bushing is provided with a rotating hole for the rotating shaft to rotate.

[0010] Preferably, the bushing is further provided with a fixing pin for connecting the drive rod, and an inner hole for accommodating the fixing pin is provided between the bushing and the drive rod.

[0011] Preferably, the device body includes a vacuum pump body and an air inlet shroud installed at one end of the vacuum pump body, and the air inlet channel is formed between the vacuum pump body and the air inlet shroud.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] (1) By adding a rotating disc and multiple connecting rods that cooperate with each other, the tilt angle of the fan blades can be adjusted when the rotating disc moves, thereby adjusting the air volume entering the air intake channel. At the same time, the adjustment process will not cause high resistance in the pipeline, reduce heat generation, and improve the service life of the equipment.

[0014] (2) The present invention uses an added moving mechanism to drive the turntable to move on the bushing via an electric push rod in the moving mechanism, thereby facilitating the automatic adjustment of the angle of multiple fan blades.

[0015] (3) By adding a rotating ring seat, a movable sleeve and a rotating groove between the turntable and the mounting plate, the turntable rotates when the bushing rotates, thus avoiding interference between the turntable and the mounting plate on the rotation of the bushing.

When the turntable 6 moves closer to or away from one side of the fan blades 15, it drives the plurality of fan blades 15 to adjust the rotation angle.

[0024] Combination Figure 1-2 As shown, the equipment body includes a vacuum pump body 1 and an air inlet shroud 2 installed at one end of the vacuum pump body 1, with an air inlet channel formed between the vacuum pump body 1 and the air inlet shroud 2.

[0025] As described above, when using the device body, drive rod 3, and air intake assembly provided by this utility model, the drive rod 3 rotates, causing the bushing 4 to rotate, thereby causing multiple fan blades 15 to rotate, and then causing gas to enter the air intake channel. When it is necessary to adjust the air volume, the turntable 6 is moved closer to or away from the side of the fan blades 15 on the bushing 4. During this process, the connecting rod 5 can drive the fan blades 15 to rotate on the bushing 4, thereby adjusting the tilt angle of the fan blades 15 on the bushing 4, and thus adjusting the air intake volume of the device. At this time, the total power of the device remains unchanged, and there is no change in the resistance in the pipeline, which increases the service life of the device.

[0026] Furthermore, to facilitate the rotational mounting of the fan blade 15 onto the bushing 4, refer to... Figure 2 As shown, the end of the fan blade 15 facing away from the connecting rod 5 is also provided with a rotating shaft 16 for rotation, and the outer wall of the bushing 4 is provided with a rotating hole 17 for the rotating shaft 16 to rotate. The fan blade 15 is rotatably mounted on the bushing 4 through the rotating shaft 16 and the rotating hole 17. The rotating shaft 16 is located on one side of the width of the fan blade 15, and the rotating shaft 16 is located on the side of the fan blade 15 facing away from the connecting rod 5.

[0027] Furthermore, to facilitate the detachable mounting of bushing 4 onto drive rod 3, refer to... Figure 2As shown, the bushing 4 is also provided with a fixing pin 10 for connecting the drive rod 3, and a recessed hole 11 for accommodating the fixing pin 10 is opened between the bushing 4 and the drive rod 3. When the bushing 4 is fitted onto the drive rod 3, the recessed hole 11 on the bushing 4 is aligned with the recessed hole 11 on the drive rod 3, and the fixing pin 10 is screwed into the recessed hole 11, thereby fixing the bushing 4 onto the drive rod 3.

[0028] In this utility model, combined with Figure 2 As shown, in this embodiment, a moving mechanism connected to the turntable 6 is provided in the air intake channel along the axial direction of the drive rod 3. The moving mechanism is used to drive the turntable 6 to move closer to or away from one side of the fan blade 15.

[0029] Combination Figure 2 As shown, the moving mechanism includes a mounting plate 14, an electric actuator 12, and a mounting bracket 13 connected in sequence. The mounting plate 14 and the mounting bracket 13 are respectively installed in the turntable 6 and the air inlet channel, and the electric actuator 12 is installed in the axial direction of the drive rod 3.

[0030] As described above, in using the moving mechanism provided by this utility model, the electric push rod 12 is controlled by an external terminal. One end of the electric push rod 12 is mounted on the inner wall of the air inlet hood 2 via the mounting bracket 13, and the other end of the electric push rod 12 is mounted on the turntable 6. When the electric push rod 12 is started, it drives the turntable 6 to move axially back and forth on the bushing 4, thereby automatically driving multiple fan blades 15 to adjust their tilt angle on the bushing 4, thereby adjusting the air intake volume of the equipment.

[0031] Furthermore, to prevent the turntable 6 and mounting plate 14 from affecting the rotation of bushing 4, refer to Figure 2-5 As shown, a movable sleeve 9, which is welded to the mounting plate 14, is fitted onto the bushing 4. A rotating groove 8 is provided on the side of the movable sleeve 9 near the turntable 6. A rotating ring seat 7 is provided on the turntable 6, which rotates in the rotating groove 8. When the bushing 4 rotates with the drive rod 3, the turntable 6 rotates accordingly via the connecting rod 5. During this process, the turntable 6 rotates on the movable sleeve 9 via the rotating groove 8 and the rotating ring seat 7. At this time, the movable sleeve 9 does not rotate, thus providing an installation position for the mounting plate 14.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
