Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, 2 and 3, an embodiment of the solar propulsion type stirring oxygenation device comprises a transmission motor 1, a water outlet 2, a tank body 3, a solar photovoltaic panel 4, a draft tube 5, a main shaft 6, a stirrer 7, a water inlet 8, a sieve plate 9, an air inlet 10, a servo motor 11, blades 12, a driven straight bevel gear 13, a driven shaft 14 and a driving straight bevel gear 15. The transmission motor is arranged above the top cover of the tank body and is coaxially connected with the main shaft; the water inlet is arranged at the position close to the bottom of the tank body; the water outlet is arranged at the position close to the top of the tank body, so that bubbles are prevented from flowing out of the water outlet without being stirred; the guide shell is arranged on the periphery of the stirrer and is a cylinder surrounding the blades; the stirrer adopts a push type stirrer, and the blades are spiral blade surfaces; the guide cylinder is matched with the stirrer, so that the flow path and the flow pattern of the water body are limited, and the axial circulation of the water body is enhanced, so that higher flow speed and circulation quantity are obtained, and the stirring efficiency is improved; the air inlet is arranged in the center of the bottom of the tank body and is connected with the air outlet end of the air pump through an air pipe; the sieve plate is round, fine and dense air holes are uniformly formed in the sieve plate, and the sieve plate is positioned above the air inlet and fixed in the tank body; the main shaft is provided with a key slot at intervals, the stirrer and the main shaft are in key connection, and the key slot installation key with the proper height is selected according to actual working requirements to fix the position of the stirrer so as to achieve the purpose of adjusting the height of the stirrer.
The invention relates to a solar intelligent oxygenation system. As shown in fig. 7, the solar intelligent oxygenation system comprises: the system comprises an oxygen dissolving instrument, a control system, a solar photovoltaic panel 4, an energy storage battery, a DC-DC converter, an oxygen dissolving device and a pitch control device. The dissolved oxygen instrument is connected with two probes, the first probe is placed in the water pool, and the second probe is placed in the water outlet body. The first probe feeds the dissolved oxygen amount of the water pool back to the control system in real time, when the dissolved oxygen amount of the water pool is lower than 2mg/L, the control system controls the solar panel to be folded, and controls the energy storage battery to convert alternating current which can be used into the alternating current through the DC-DC converter to supply power for the dissolved oxygen device and the variable pitch device. The second probe feeds back the dissolved oxygen information of the water body at the water outlet to the control system in real time, if the dissolved oxygen is not saturated, the control system controls the micro servo motor 11 to start, and the pitch adjusting mechanism drives the blades 12 to rotate by an angle at regular intervals. Until the water dissolved oxygen data at the water outlet transmitted back by the second probe reaches the requirement, the micro servo motor is powered off, the stirrer blade is stirred at a fixed angle, and the oxygenation device starts to operate stably. When the dissolved oxygen amount in the water pool reaches 4mg/L, the control system controls the energy storage battery to be closed, the dissolved oxygen device and the variable pitch device are in a standby state, and the solar panel is controlled to be supported to charge the energy storage battery.
The transmission motor 1 is directly arranged above the top cover of the tank body 3, so that the energy loss can be reduced, the structure of the oxygenation device is more compact, and the space is saved. And the motor is located delivery port top, can avoid the motor to meet water and damage.
When the dissolved oxygen in water is in a normal range, the solar photovoltaic panels 4 around the tank body are supported to charge the storage battery.
When the first probe of the dissolved oxygen meter monitors that the dissolved oxygen in water is lower than 2mg/L, the control system rapidly makes a response, the water pump is started to fill water into the tank body 3, and the water inlet flow is 50m3And h, the water flow diffuses and moves around after being accelerated by the stirrer 7, the water flow is beaten inside the guide shell and changes the original circumferential motion into axial motion under the limitation of the guide shell, so that water discharged by the blades 12 forms up-and-down circular flow inside and outside the guide shell.
Simultaneously, bottom aeration equipment also begins work, and air inlet 10 admits air, and through a large amount of tiny bubbles of fine pore dispersion on the sieve 9 get into the aquatic, the rivers that roll at a high speed drive the bubble and also constantly collide in the agitator, and at this in-process, the bubble can constantly be broken and form littleer bubble, and fine bubble greatly increased the area of contact of air with the water, be favorable to dissolving of oxygen. The water and air after oxygenation are discharged from a water outlet positioned above.
The working principle of changing the pitch of the invention is as follows: after the oxygenation device is started, the second probe of the dissolved oxygen meter monitors the dissolved oxygen amount of the water body discharged from the water outlet in real time. If the dissolved oxygen data fed back to the control system does not reach more than 95% of the dissolved oxygen at the air temperature, a micro servo motor arranged in the hub of the pitch-variable stirrer is started. The servo motor 11 drives the driving straight bevel gear 10 to rotate for an angle, the driven straight bevel gear 13 is driven to rotate for an angle through gear meshing, the driven straight bevel gear is in key connection with the driven shaft 14, the driven shaft and the driven straight bevel gear rotate synchronously, the blades 12 are fixed on the driven shaft, the angle is changed accordingly, and therefore the purpose of pitch changing is achieved. The servo motor continuously changes the angle after receiving the signal, and the control system receives the water outlet dissolved oxygen data when the paddle is at different angles. When the dissolved oxygen measured by the second probe reaches the standard, the control system controls the micro servo motor to stop running, at the moment, the paddle is fixed at a certain angle, and the oxygenation device recovers stable operation.
When the dissolved oxygen in the water body of the water pool measured by the first probe of the dissolved oxygen instrument reaches 4mg/L, the control system controls all the devices to stop running.
Repeated tests prove that the oxygen adding effect is obvious.
