Abstract
Description
Technical Field
[0001] This utility model relates to the field of spirulina cultivation technology, specifically a stirring device for spirulina cultivation. Background Technology
[0002] Spirulina is a type of lower organism, a prokaryote, consisting of filamentous bodies composed of single or multicellular cells. It is cylindrical and has a loose or tight, regular spiral shape, resembling a clockwork spring, hence its name. Spirulina is usually cultivated in aquaculture ponds. In order to mix the carbon dioxide released in the aquaculture pond with the culture medium, and to ensure that the algae solution is evenly exposed to light, has sufficient gas exchange, and is evenly distributed in the culture medium, a stirring device is usually used. The stirring device is usually set up above the aquaculture pond, and the stirring blades agitate the water in the pond to achieve the purpose of stirring the spirulina.
[0003] When existing stirring devices agitate the pool water, the stirring blades can only move the water in one direction. However, since the aquaculture pool has a certain depth, the upper layer of spirulina receives sufficient light, while the lower layer receives insufficient light. The stirring blades are not good at stirring the lower layer of spirulina to the upper layer, resulting in uneven light exposure and potentially causing significant differences in the growth of spirulina. Utility Model Content
[0004] The purpose of this invention is to provide a stirring device for spirulina cultivation to solve the problems mentioned in the background art.

[0006] A stirring device for spirulina cultivation, comprising:
[0007] A stirring assembly, the stirring assembly including a rotating shaft, a plurality of mounting brackets provided on the outer side of the rotating shaft, and stirring blades fixedly mounted on one side of the mounting brackets;
[0008] A toggle assembly is located on both sides of the stirring blade;
[0009] A circulation assembly is disposed below the stirring blade. The circulation assembly includes a circulation pipe, a plurality of storage pipes are fixedly connected at equal intervals on the outer surface of the circulation pipe, and water outlet pipes are fixedly connected at both ends of the outer surface of the circulation pipe. A piston rod is slidably connected inside the storage pipe.
[0010] A guide assembly is disposed inside the circulation tube, and the guide assembly includes a connecting rod that is fixedly connected to multiple piston rods.
[0011] Furthermore, an installation plate is fixedly installed on the outer surface of the circulation pipe, and one-way valves are fixedly installed at both ends of the circulation pipe and inside the outlet pipe.
[0012] Furthermore, a spring is movably sleeved on the outside of the piston rod, and the two ends of the spring are fixedly connected to the storage tube and the connecting rod, respectively.
[0013] Furthermore, a sliding rod is symmetrically and fixedly installed on the outer surface of the circulation pipe, and a sliding sleeve is slidably connected to the outer side of the sliding rod, and the sliding sleeve is fixedly connected to the connecting rod.
[0014] Furthermore, a fixing rod is fixedly installed on the outer surface of the connecting rod, and a guide frame is fixedly installed on the upper end of the fixing rod.
[0015] Furthermore, the outer surfaces of the rotating shaft are connected to bearing seats at both ends by bearings, one end of the rotating shaft is connected to a motor that can drive the rotating shaft to rotate, a first collar is fixedly installed on the outer side of the rotating shaft, and the plurality of mounting brackets are fixedly connected to the first collar.
[0016] Preferably, the toggle assembly includes:
[0017] Two No. 2 collars are fixedly installed at both ends of the outer surface of No. 1 collar;
[0018] Multiple adjustable telescopic rods are fixedly installed at equal angles on the outer surface of the No. 2 collar;
[0019] The lever is fixedly installed on one end of the adjustable telescopic rod.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. The motor drives the stirring blades to rotate, moving the spirulina inside the aquaculture pond from above. The adjustable telescopic rod can be adjusted and fixed in length using a knob on one side, allowing it to abut against guide frames at different positions to accommodate aquaculture ponds of varying depths.
[0022] 2. When the lever rotates, it presses against the bottom of the guide frame, pushing the guide frame upward and causing the piston rod to move upward. This creates suction inside the circulation pipe, drawing water into the circulation pipe. When the lever separates from the guide frame, the spring's elasticity contracts, causing the connecting rod to move downward and the piston rod to move downward. This pushes the water inside the circulation pipe out of the upper end of the outlet pipe. As the stirring blades rotate, they push the water and spirulina upward from the bottom of the aquaculture pond. When the spirulina is moved, it pushes the bottom spirulina upward, ensuring even light exposure for spirulina in different locations and reducing growth differences. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-5 In this embodiment of the present invention, a stirring device for spirulina cultivation includes a stirring assembly 1, which includes a rotating shaft 102. Multiple mounting brackets 105 are provided on the outer side of the rotating shaft 102. A stirring blade 106 is fixedly installed on one side of the mounting bracket 105. A tossing assembly 2 is provided on both sides of the stirring blade 106. A circulation assembly 3 is provided below the stirring blade 106. The circulation assembly 3 includes a circulation pipe 302. Multiple storage pipes 304 are fixedly connected at equal intervals on the outer surface of the circulation pipe 302. Water outlet pipes 303 are fixedly connected at both ends of the outer surface of the circulation pipe 302. A piston rod 305 is slidably connected inside the storage pipe 304. A guide assembly 4 is provided inside the circulation pipe 302. The guide assembly 4 includes a connecting rod 401 fixedly connected to the multiple piston rods 305.
[0031] Specifically, the stirring component 1 stirs the spirulina from above the aquaculture pond, and the agitator component 2 drives the piston rod 305 to move up and down. With the cooperation of the circulation pipe 302, the pond water and spirulina surge from the bottom of the aquaculture pond upwards, causing the spirulina at the bottom of the aquaculture pond to surge upwards.
[0032] Example 1
[0033] like Figure 1 and Figure 2 As shown, in this embodiment, bearing seats 101 are connected to both ends of the outer surface of the rotating shaft 102 via bearings. The bearing seats 101 are fixed above the aquaculture pond to support the rotating shaft 102. One end of the rotating shaft 102 is connected to a motor 103 that can drive the rotating shaft 102 to rotate. The motor 103 is fixed to the edge of the aquaculture pond so that the motor 103 can drive the rotating shaft 102 to rotate. A first collar 104 is fixedly installed on the outer side of the rotating shaft 102, and multiple mounting brackets 105 are fixedly connected to the first collar 104. The actuating assembly 2 includes: two second collars 201 are fixedly installed at both ends of the outer surface of the first collar 104, multiple adjustable telescopic rods 202 are fixedly installed at equal angles on the outer surface of the second collars 201, and a lever 203 is fixedly installed on one end of the adjustable telescopic rod 202.
[0034] In this embodiment, the motor 103 operates, driving the rotating shaft 102 to rotate, causing the stirring blades 106 to rotate, which moves the spirulina inside the culture pond from above. The adjustable telescopic rod 202 can be adjusted and fixed in length by a knob on one side, so that the lever 203 can abut against the guide frame 405 at different positions to adapt to culture ponds of different depths.
[0035] like Figure 3 and Figure 4 As shown, in this embodiment, an installation plate 301 is fixedly installed on the outer surface of the circulation pipe 302. The circulation pipe 302 is installed at the bottom of the aquaculture pond through the installation plate 301. One-way valves 306 are fixedly installed at both ends of the circulation pipe 302 and inside the outlet pipe 303. A spring 403 is movably sleeved on the outer side of the piston rod 305. The two ends of the spring 403 are fixedly connected to the storage pipe 304 and the connecting rod 401, respectively. A fixing rod 404 is fixedly installed on the outer surface of the connecting rod 401. A guide frame 405 is fixedly installed on the upper end of the fixing rod 404.
[0036] In practice, the one-way valves 306 at both ends of the circulation pipe 302 ensure that the pool water can only enter from both ends of the circulation pipe 302 and then exit through the one-way valve 306 inside the outlet pipe 303. When the lever 203 rotates, it presses against the bottom of the guide frame 405, pushing the guide frame 405 upward and causing the piston rod 305 to move upward, generating suction inside the circulation pipe 302, which allows the pool water to enter the circulation pipe 302. When the lever 203 separates from the guide frame 405, the elasticity of the spring 403 causes the connecting rod 401 to move downward, causing the piston rod 305 to move downward, pushing the pool water inside the circulation pipe 302 out of the top of the outlet pipe 303. Thus, when the stirring blade 106 rotates, it pushes the pool water and spirulina upward from the bottom of the aquaculture pond. When the spirulina is moved, it pushes the spirulina at the bottom to the top, making the spirulina in different positions evenly exposed to light and reducing the growth differences of spirulina.
[0037] Example 2
[0038] Based on Embodiment 1, in order to compensate for the poor stability of the piston rod 305 during movement.
[0039] like Figure 3 and Figure 4 As shown, in this embodiment, a slide rod 406 is symmetrically fixedly installed on the outer surface of the circulation pipe 302, and a slide sleeve 402 is slidably connected to the outer side of the slide rod 406. The slide sleeve 402 is fixedly connected to the connecting rod 401.
[0040] In practice, the sliding connection between the slide rod 406 and the slide sleeve 402 allows the connecting rod 401 and the piston rod 305 to move only along the direction of the slide rod 406, increasing the stability of the piston rod 305's up-and-down movement and preventing the piston rod 305 from falling out of the storage tube 304.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
