The hydraulic drive mechanism 20 may include a left reservoir 21 suspended from the left boom 121, a right reservoir 22 suspended from the right boom 122, and a liquid guide tube 23 communicating with the left reservoir 21 and the right reservoir 22, the left reservoir 21 and the right reservoir 22 being respectively for storing the liquid W so that the lever center of gravity is lower than the lever fulcrum. The adjustable weight adjustment mechanism 30 is controlled to adjust the weight of the left cantilever 121 and/or the right cantilever 122 of the lever member 12 to change the inclination angle of the lever member 12 to form a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22, so that the liquid W flows between the left liquid storage container 21 and the right liquid storage container 22 through the liquid guide tube 23 by its own weight force to swing the lever member 12 to different inclination angles along with the flow of the liquid W.
It will be appreciated that reference herein to a fulcrum point may refer to the point of support provided by the fulcrum element 11 to the lever element 12; the lever center of gravity referred to herein may be the combined center of gravity of the lever member 12 and the hydraulic drive mechanism 20. Furthermore, the fulcrum element 11 of the lever mechanism 100 of the present application may provide a center of rotation point 101 of the rocking mechanism 10; the left cantilever 121 and the right cantilever 122 in the lever member 12 of the lever mechanism 100 may provide a left mounting location 102 and a right mounting location 103, respectively, of the rocking mechanism 10.
It is noted that, according to the mechanical principle of the lever, for the lever with the center of gravity lower than the fulcrum, after the weights on the left side and the right side of the lever are adjusted, the lever can rotate around the fulcrum until a certain inclination angle is reached to achieve new lever balance adjustment; that is, after the left and right counterweights of the lever are adjusted, the lever is rotated and stably maintained in the moment-balanced tilting posture until the left and right counterweights of the lever are adjusted again to be rotated again to a new tilting posture. The present application thus uses this principle to design the hydraulic rocking device 1 to use hydraulic drive to achieve the rocking effect of the lever, i.e. to use the change in the difference in weight of the liquid W in the left reservoir 21 and the right reservoir 22 to adjust the tilt angle of the lever member 12.
Alternatively, the liquid W mentioned in the present application may not be limited to be implemented as water; of course, in other examples of the present application, the liquid W mentioned in the present application may be implemented as a fluid such as a solution or an organic solvent, so long as it can flow between the left liquid storage container 21 and the right liquid storage container 22 through the liquid guide tube 23, which will not be described in detail herein.
According to the above-described embodiment of the present application, when the adjustable weight mechanism 30 is controlled to decrease the weight of the left mounting location 102 and/or increase the weight of the right mounting location 103, the rocking mechanism 10 is rotated clockwise by the weight moment to raise the left liquid storage container 21 and to depress the right liquid storage container 22 such that the liquid level in the left liquid storage container 21 is higher than the liquid level in the right liquid storage container 22; when the adjustable weight deployment mechanism 30 is controlled to increase the weight of the left mounting location 102 and/or decrease the weight of the right mounting location 103, the rocking mechanism 10 is rotated counterclockwise under the influence of the weight moment to depress the left reservoir 21 and raise the right reservoir 22 such that the liquid level in the right reservoir 22 is higher than the liquid level in the left reservoir 21.
Illustratively, as shown in FIG. 4, when the adjustable weight mechanism 30 is controlled to decrease the weight of the left boom 121 and/or increase the weight of the right boom 122, the lever member 12 is rotated clockwise under the influence of the weight moment to raise the left reservoir 21 and depress the right reservoir 22 such that the liquid level in the left reservoir 21 is higher than the liquid level in the right reservoir 22; at this time, the liquid W stored in the left liquid storage container 21 will flow into the right liquid storage container 22 through the liquid guide tube 23, so that the weight of the left cantilever 121 is further reduced, and the weight of the right cantilever 122 is further increased, and thus the lever member 12 will be further rotated clockwise to a different inclination angle with the flow of the liquid W until the lever member 12 is rotated clockwise to a new inclination angle to reach a new lever balance condition after the flow of the liquid W is stopped.
Similarly, as shown in fig. 5, when the adjustable weight mechanism 30 is controlled to increase the weight of the left cantilever 121 and/or decrease the weight of the right cantilever 122, the lever member 12 rotates counterclockwise under the action of the weight moment to depress the left liquid storage container 21 and raise the right liquid storage container 22 such that the liquid level in the left liquid storage container 21 is lower than the liquid level in the right liquid storage container 22; at this time, the liquid W stored in the right liquid storage container 22 will flow into the left liquid storage container 21 through the liquid guide tube 23, so that the weight of the left cantilever 121 is further increased, and the weight of the right cantilever 122 is further decreased, and thus the lever member 12 will be further rotated counterclockwise to a different inclination angle along with the flow of the liquid W until the lever member 12 is rotated counterclockwise to a new inclination angle to reach a new lever balance condition after the flow of the liquid W is stopped.
It should be noted that the inclination angle of the lever element 12 is determined by the weight difference between the left cantilever 121 and the right cantilever 122, and the maximum weight moment difference between the left and right sides can be calculated according to the maximum inclination angle to be achieved, so as to calculate the weight of the liquid to be stored in the left liquid storage container 21 and the right liquid storage container 22. It will be appreciated that the volumes of the left reservoir 21 and the right reservoir 22 are each no less than the volume of liquid required to be stored.
Alternatively, as shown in fig. 2 and 3, one end of the liquid guide tube 23 is connected to the bottom opening of the left liquid storage container 21, and the other end of the liquid guide tube 23 is connected to the bottom opening of the right liquid storage container 22, so as to ensure that the liquid W stored in the left liquid storage container 21 can completely flow into the right liquid storage container 22, and the liquid W stored in the right liquid storage container 22 can also completely flow into the left liquid storage container 21, thereby maximizing the use of the stored liquid W.
In order to ensure that the liquid W stored in the left and right liquid storage containers 21 and 22 can smoothly flow through the liquid guide tube 23 by gravity, the left and right liquid storage containers 21 and 22 of the present application may be further provided with a top opening to balance the air pressure difference between the left and right liquid storage containers 21 and 22.
Optionally, as shown in fig. 2 and 3, the hydraulic driving mechanism 20 of the present application may further include an air duct 24, where one end of the air duct 24 is connected to the top opening of the left liquid storage container 21, and the other end of the air duct 24 is connected to the top opening of the right liquid storage container 22, so that the hydraulic driving mechanism 20 forms a relatively closed system, and can effectively avoid volatilization or overflow of the liquid W while ensuring smooth flow of the liquid W between the left liquid storage container 21 and the right liquid storage container 22 through the liquid duct 23.
It will be appreciated that in other examples of the present application, the hydraulic drive mechanism 20 of the present application may include spill-resistant devices disposed on the left reservoir 21 and the right reservoir 22. For example, the spill-proof device of the present application may be implemented, but is not limited to, as a buoyancy valve for closing the top opening when the liquid level in the container rises to a predetermined height; or closing the bottom opening when the liquid level in the container drops to a predetermined level, the liquid W can be prevented from flowing through the liquid guide tube 23, and the effect of preventing the liquid W from overflowing can be achieved.
Alternatively, as shown in fig. 2 and 3, the left and right liquid storage containers 21 and 22 are flexibly suspended from the left and right cantilevers 121 and 122, respectively, so as to facilitate liquid level difference measurement while reducing the occupied space. It is to be understood that the flexible connection referred to in this application may be implemented as, but is not limited to, a hinged or a flexible rope connection; of course, in other examples of the present application, the left reservoir 21 and the right reservoir 22 may also be rigidly connected to the left cantilever 121 and the right cantilever 122, respectively.
It should be noted that the installation position of the liquid storage container on the rocking mechanism 10 needs to be selected according to the self structure and external space condition of the hydraulic rocking device 1; the force arm of the hydraulic driving mechanism 20 applied to the lever element 12 will be changed due to different mounting positions, and the shorter the force arm is, the greater the weight of the counterweight to be applied by the hydraulic driving mechanism 20 is, i.e. the more liquid W is to be stored; thus, as shown in fig. 2 and 3, the left liquid storage container 21 and the right liquid storage container 22 of the present application are flexibly connected to the free ends of the left cantilever 121 and the right cantilever 122, respectively, so as to maximize the force arm and reduce the required liquid amount. It will be appreciated that the free ends of the left and right cantilevers 121,122 now act as the left and right mounting locations 102,103, respectively.
Optionally, the catheter 23 and/or the air duct 24 may be implemented as a hose to avoid interfering with the natural suspension of the left reservoir 21 and the right reservoir 22 when the lever element 12 is turned, in order to simplify the mechanical analysis. It will be appreciated that in other examples of the present application, the catheter 23 and/or the airway 24 may also be implemented as a hard tube, which will not be described in detail herein.
It is noted that the left liquid storage container 21 and the right liquid storage container 22 of the present application may be implemented as containers having the same shape and capacity; of course, in other examples of the present application, the left liquid storage container 21 and the right liquid storage container 22 may also be implemented as containers having different shapes and/or capacities, which will not be described herein.
Alternatively, the left liquid storage container 21 and the right liquid storage container 22 of the present application may be implemented as cylindrical containers such as drums or the like. Of course, in other examples of the present application, the left liquid storage container 21 and the right liquid storage container 22 may also be implemented as ball-type containers or other types of containers, which will not be described herein.
It should be noted that, when the left liquid storage container 21 and the right liquid storage container 22 store different weights of liquid W, respectively, the lever member 12 will satisfy a lever balance condition at a certain inclination angle to be stably maintained at the inclination angle; while as liquid W flows between the left reservoir 21 and the right reservoir 22 through the catheter 23, the lever member 12 will rotate to different tilt angles to meet the lever equilibrium condition; at the same time, the rotational speed of the lever member 12 depends on the amount of flow of the liquid W through the catheter 23, that is, the greater the flow of the liquid W, the faster the rotational speed of the lever member 12. In other words, the hydraulic swing device 1 of the present application can control the rotation speed of the lever member 12 by controlling the flow rate of the liquid W in the liquid guide tube 23, thereby controlling the time required for the lever member 12 to rotate from one inclination angle to another inclination angle, so as to meet specific application requirements.
Alternatively, as shown in fig. 4 and 5, the hydraulic rocking device 1 of the present application may comprise a flow valve 25 provided to the catheter 23, the flow valve 25 being controlled to switch on or off the catheter 23 to allow or prevent liquid flow in the catheter 23 and to control the rocking mechanism 10 to start or stop rotation.
In other words, when the flow valve 25 is controlled to intercept the liquid guide tube 23, the lever member 12 is balanced at a certain inclination angle so that there is a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22; and when the flow valve 25 is controlled to conduct the liquid guide tube 23, the liquid guide tube 23 serves to flow the liquid W stored in the left and right liquid storage containers 21 and 22 by the liquid level difference to automatically rotate the lever member 12 counterclockwise or clockwise.
Notably, the flow valve 25 may be implemented as, but is not limited to, a solenoid valve, in order to automatically control the on-off of the catheter 23. Of course, in other examples of the present application, the flow valve 25 may also be implemented as a manual valve.
Preferably, as shown in fig. 8, the flow valve 25 is a proportional control valve 250 for changing the flow cross-sectional area of the liquid guide tube 23 to continuously adjust the flow rate of the liquid through the liquid guide tube 23 to control the rotation speed of the rocking mechanism 10. In other words, the flow valve 25 also has a flow regulating function; that is, the flow valve 25 is further used for adjusting the flow area of the liquid guide tube 23 to adjust the flow rate of the liquid W stored in the left liquid storage container 21 and the right liquid storage container 22 passing through the liquid guide tube 23, so as to adjust the rotation speed of the rocking mechanism 10, so as to meet the rotation time demands of different seasons, such as a faster rotation speed in winter than summer, so as to shorten the rotation time, and facilitate tracking the sun better for rocking.
It is noted that the lever member 12 in the hydraulic swing device 1 of the present application is adapted to swing between a left limit inclination angle and a right limit inclination angle, wherein when the lever member 12 is rotated to the left limit inclination angle or the right limit inclination angle, the liquid level in the left liquid storage container 21 is flush with the liquid level in the right liquid storage container 22, so that the liquid W does not flow through the liquid guide tube 23 due to the absence of the liquid level difference, so as to be stably maintained at the left limit inclination angle or the right limit inclination angle. It will be appreciated that reference herein to the left limit angle of inclination refers to the maximum angle of inclination at which the lever member 12 rotates anticlockwise; accordingly, the right limit inclination angle refers to the maximum inclination angle at which the lever member 12 rotates clockwise.
Alternatively, as shown in fig. 2 and 3, on the premise that the liquid level in the left liquid storage container 21 is flush with the liquid level in the right liquid storage container 22, the lever element 12 satisfies a lever balance condition at the left limit inclination angle or the right limit inclination angle, so that the lever balance condition can be broken only by applying a very small weight difference through the adjustable weight adjustment mechanism 30 while stably maintaining at the left limit inclination angle or the right limit inclination angle, so that the lever element 12 rotates to form a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22, thereby starting the automatic rotation of the lever element 12 to realize the effect of four-two jack.
Preferably, as shown in fig. 2, when the lever member 12 is rotated counterclockwise to the left limit inclination angle, the bottom wall of the right liquid storage container 22 is flush with the liquid level in the left liquid storage container 21, so that the liquid W stored in the right liquid storage container 22 completely flows into the left liquid storage container 21; when the lever member 12 is rotated clockwise to the right limit inclination angle, as shown in fig. 3, the bottom wall of the left liquid storage container 21 is flush with the liquid level in the right liquid storage container 22, so that the liquid W stored in the left liquid storage container 21 completely flows into the right liquid storage container 22. In this way, the total amount of liquid W stored in the left and right liquid storage containers 21, 22 is minimized, but sufficient to drive the lever member 12 to swing between the left and right extreme tilt angles.
More preferably, as shown in fig. 2, when the lever member 12 is rotated counterclockwise to the left limit inclination angle, the bottom wall of the right liquid storage container 22 is flush with the top wall of the left liquid storage container 21, so that the left liquid storage container 21 is just filled after the liquid W stored in the right liquid storage container 22 completely flows into the left liquid storage container 21; when the lever member 12 is rotated clockwise to the right limit inclination angle, as shown in fig. 3, the bottom wall of the left liquid storage container 21 is flush with the liquid level in the right liquid storage container 22, so that the right liquid storage container 22 is just filled after the liquid W stored in the left liquid storage container 21 completely flows into the right liquid storage container 22. In this way, the left reservoir 21 and the right reservoir 22 have a minimum capacity to just hold the liquid W providing the hydraulic drive to fully utilize the reservoir capacity.
Illustratively, as shown in fig. 1, when the lever element 12 is in a horizontal posture, the left cantilever 121 in the lever element 12 extends obliquely leftward and downward from the fulcrum element 11, and the right cantilever 122 extends obliquely rightward and downward from the fulcrum element 11 to ensure that the center of gravity of the lever element 12 is located below the fulcrum of the fulcrum element 11.
Assuming that the left and right total masses of the lever (i.e., the sum of the left and right masses of the lever member 12, the hydraulic drive mechanism 20, and the adjustable weight mechanism 30) are concentrated at the free ends of the left and right cantilevers 121, 122, respectively, the left and right total masses of the lever are each 7.5Kg; the length of the left cantilever 121 and the right cantilever 122 is 1 meter; the angle between the left cantilever 121 and the right cantilever 122 is 170 °, that is, when the lever element 12 is in the horizontal posture, the angles between the left cantilever 121 and the right cantilever 122 and the horizontal plane are 5 °; the left and right extreme tilt angles of the lever member 12 are each 30 °.
Thus, when the lever member 12 is rotated counterclockwise to the left limit inclination angle, the angle between the left cantilever 121 of the lever member 12 and the horizontal plane is 35 ° and the angle between the right cantilever 122 and the horizontal plane is 25 °; at this time, the left moment arm of the lever element 12 is 1×cos35° meter, and the right moment arm is 1×cos25° meter; in order to ensure that the lever member 12 meets the lever balance condition (i.e., torque balance) at the left limit inclination angle, the left liquid storage container 21 stores a mass m of liquid 1 Needs to satisfy (7.5+m) 1 ) G 1×cos35° =7.5×1×cos25°, i.e. the mass m of liquid stored in the left liquid storage container 21 1 ＝0.798Kg。
Likewise, when the lever member 12 is rotated clockwise to the left limit inclination angle, the angle between the right cantilever 122 of the lever member 12 and the horizontal plane is 35 °, and the angle between the left cantilever 121 and the horizontal plane is 25 °; at this time, the right arm of force of the lever element 12 is 1×cos35° meter, and the left arm of force is 1×cos25° meter; in order to ensure that the lever member 12 meets the lever balance condition (i.e., torque balance) at the right limit inclination angle, the mass m of the liquid stored in the right liquid storage container 22 is greater 2 Needs to satisfy (7.5+m) 2 ) G 1×cos35° =7.5×1×cos25°, i.e. the mass m of liquid stored in the right liquid container 22 2 ＝0.798Kg。
To sum up, in the above example of the present application, the total amount of the liquid stored in the left liquid storage container 21 and the right liquid storage container 22 is at least 0.798Kg, so that the hydraulic driving requirement that the lever member 12 swings between the counterclockwise inclination of 30 ° and the clockwise inclination of 30 ° can be satisfied. In addition, the heights of the left reservoir 21 and the right reservoir 22 of the present application are each implemented as 1×sin35° +1×sin25° =0.9962 meters. Since 0.798Kg of water corresponds to 798mL of water, the left reservoir 21 and the right reservoir 22 of the present application are each 798mL in volume, so that the liquid level in the left reservoir 21 will drop by 1.25mm for each gram of water flowing out of the left reservoir 21, and correspondingly the liquid level in the right reservoir 22 will rise by 1.25mm.
It should be noted that the adjustable weight-balancing mechanism 30 of the present application can be controlled to apply a weight of 0.05Kg to the free end of the left cantilever 121 or the right cantilever 122 to break the original lever balance condition of the lever member 12, so that the lever member 12 automatically rotates to form a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22. And the measurement and calculation show that: when the adjustable weight-adjusting mechanism 30 applies a weight of 0.05Kg to the free end of the right cantilever 122, the level of the liquid in the left liquid storage container 21 is always higher than the level of the liquid in the right liquid storage container 22 during the process of rotating from the left limit inclination angle to the right limit inclination angle, so as to ensure that the liquid W completely flows into the right liquid storage container 22 from the left liquid storage container 21; when the weight of 0.05Kg is applied to the free end of the left cantilever 121 by the adjustable weight-adjusting mechanism 30, the liquid level in the right liquid storage container 22 is always higher than the liquid level in the left liquid storage container 21 during the process of rotating from the right limit inclination angle to the left limit inclination angle, so as to ensure that the liquid W can completely flow into the left liquid storage container 21 from the right liquid storage container 22.
It will be appreciated that the adjustable weighing mechanism 30 of the present application can utilize the hydraulic driving mechanism 20 to drive the 15Kg lever to swing between the left limit inclination angle and the right limit inclination angle by applying only 0.05Kg of counterweight as an actuating force, thereby achieving the effect of small and large. In addition, the weight of 0.05Kg applied by the adjustable weight mechanism 30 is only an example, and the weight that breaks the lever balance condition and provides the starting force can be less than 0.05Kg, which is not repeated in the present application.
It should be noted that, as shown in fig. 1 to 5, the adjustable weight mechanism 30 of the present application includes a left weight container 31 and/or a right weight container 32 disposed on the rocking mechanism 10, where the left weight container 31 and/or the right weight container 32 are used for injecting or discharging a predetermined mass of liquid, respectively, so as to change the center of gravity of the hydraulic rocking device 1 to make the rocking mechanism 10 start to rotate, thereby forming a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22.
Illustratively, in one example of the present application, as shown in fig. 4 and 5, the adjustable weight mechanism 30 may include a left weight container 31 provided to the left cantilever 121 and a right weight container 32 provided to the right cantilever 122, the left weight container 31 and the right weight container 32 being used to be filled with or discharged from a predetermined mass of liquid W, respectively, to break a lever balance condition of the lever member 12 at the left and right extreme inclination angles such that the lever member 12 rotates to always form a liquid level difference between the left and right liquid storage containers 21 and 22. It will be appreciated that the predetermined mass referred to herein may be, but is not limited to, a counterbalance mass implemented to be able to break the leverage balance condition of the lever member 12 at the left and right extreme tilt angles to cause the lever member 12 to rotate to always create a level difference, such as 0.05Kg in the example above.
Thus, as shown in fig. 4, when the liquid W is discharged from the left weight container 31 and the liquid W is injected into the right weight container 32, the lever balance condition of the lever member 12 at the left limit inclination angle is broken, at which time the lever member 12 rotates clockwise to make the liquid level in the left liquid storage container 21 higher than the liquid level in the right liquid storage container 22, and further, as the liquid W flows from the left liquid storage container 21 into the right liquid storage container 22, the lever member 12 rotates automatically from the left limit inclination angle to the right limit inclination angle. Also, as shown in fig. 5, when the liquid W is discharged from the right weight container 32 and the liquid W is injected into the left weight container 31, the lever balance condition of the lever member 12 at the right limit inclination angle is broken, at which time the lever member 12 rotates counterclockwise to make the liquid level in the right liquid storage container 22 higher than the liquid level in the left liquid storage container 21, and further, as the liquid W flows from the right liquid storage container 22 into the left liquid storage container 21, the lever member 12 rotates automatically from the right limit inclination angle to the left limit inclination angle.
Alternatively, the volumes of the left and right weighted receptacles 31, 32 of the present application are each equal to the volume of the predetermined mass of water, such that the left and right weighted receptacles 31, 32 need only be correspondingly filled or emptied of water to achieve the effect of initiating a hydraulic drive.
Preferably, as shown in fig. 2 and 3, the left weight container 31 is fixedly attached to the left liquid storage container 21 such that the left weight container 31 is suspended from the free end of the left cantilever 121; the right weighted container 32 is secured to the right reservoir 22 such that the right weighted container 32 is suspended from the free end of the right cantilever arm 122.
It will be appreciated that the left and right weighted receptacles 31 and 32 of the present application may be filled and drained in an automated manner using, but not limited to, solenoid valves, where water filling and draining may be automatically controlled by the addition of a water level switch or a timer switch. Of course, in another example of the present application, the adjustable weight mechanism 30 may also include only the left weight container 31 (the right weight container 32), where the capacity of the left weight container 31 (the right weight container 32) is twice the water volume of the predetermined mass, and the difference between the total right (left) and left (right) mass of the lever is equal to the predetermined mass, so that the lever element 12 can be started to automatically rotate from the right limit inclination angle to the left limit inclination angle by only filling the left weight container 31 (the right weight container 32) with water; or evacuating the left weighted container 31 (the right weighted container 32), the lever member 12 can be actuated to automatically rotate from the left limit angle of inclination to the right limit angle of inclination.
It is noted that in other examples of the present application, the adjustable weight mechanism 30 may also be implemented as other types of reciprocating mechanisms that are controlled to drive a counterweight to reciprocate between the left mounting position 102 and the right mounting position 103 to break the leverage balance condition of the rocking mechanism 10 at the left and right extreme tilt angles.
Illustratively, the adjustable weight adjustment mechanism 30 may also include a reciprocating mechanism and a weight block disposed on the rocking mechanism 10, wherein the reciprocating mechanism is controlled to move the weight block leftwards or rightwards to change the gravity center of the hydraulic rocking device 1 so as to start the rocking mechanism 10 to rotate, thereby forming a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22.
In other words, the reciprocating mechanism is controlled to drive the balancing weight to move back and forth on both the left and right sides of the lever member 12 to break the lever balance condition of the lever member 12 at the left and right extreme inclination angles, so that the lever member 12 rotates to always form a liquid level difference between the left and right liquid storage containers 21 and 22. It will be appreciated that the reciprocator may be implemented as a transmission consisting of a motor and gears, with the weight being drawn by a chain to move left and right along the lever element, such as by using a stepper motor to control the reciprocation of the weight, or by using a conventional motor in combination with a limit mechanism to control the reciprocation of the weight, etc.; the reciprocating mechanism may also be implemented as an electromagnetic driving mechanism to drive the rolling armature to move left and right in the pipeline, such as using an electromagnetic attraction device to attract the armature to reciprocate or using an electromagnetic spring device to eject the armature to reciprocate, which will not be described in detail in this application.
It is noted that in the above example of the present application, the fulcrum of the rocking mechanism 10 in the hydraulic rocking device 1 is implemented as the rotation center point 101 such that the fulcrum position of the rocking mechanism 10 is unchanged at the time of rotation, that is, the hydraulic rocking device 1 rotates around the fulcrum of the rocking mechanism 10. However, in other examples of the present application, the rocking mechanism 10 may be implemented as a mechanism having a tumbler structure such as a half-roller mechanism, and the desired rocking motion can be achieved by the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 of the present application as long as the center of gravity of the whole is below the center of rotation, although the fulcrum is not fixed.
Illustratively, in other examples of the present application, as shown in fig. 12 and 15, the rocking mechanism 10 is implemented as a reciprocatingly rollable half-cylinder mechanism 100', the fulcrum and the rotational center point of the half-cylinder mechanism 100' being not one point. In this way, the rocking mechanism 10 rolls on the support surface when rocking, and the contact point between the rocking mechanism 10 and the support surface moves during rolling, so that the fulcrum of the rocking mechanism 10 is not fixed in position during rolling. At this time, when the hydraulic rocking device 1 force-balances and stabilizes the posture without an external force, the fulcrum position of the half-drum mechanism 100' serves as a fulcrum, and left and right mounting positions 102 and 103 are provided on the left and right sides of the fulcrum, respectively. Further, the rocking mechanism 10 has its center of gravity and fulcrum on the same vertical line and its center of gravity below the rotation center point 101 at the time of force balance stable posture. It will be appreciated that this example of the present application is still capable of utilizing the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 such that the center of gravity of the rocking mechanism 10 is always below the center of rotation point 101 when a side-to-side rolling rotation is achieved.
Alternatively, as shown in FIG. 15, the semi-roller mechanism 100' may roll on a horizontal support surface; alternatively, as shown in FIG. 12, the semi-roller mechanism 100' may also roll on an arcuate bearing surface to add balls or rollers therebetween to facilitate reduced rolling friction.
It should be noted that the mounting positions of the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 on the rocking mechanism 10 need to be selected according to the own structure and external space conditions of the hydraulic rocking device 1. Although in the above examples of the present application, the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 are each disposed in the inner space of the rocking mechanism 10, this is merely an example, and in other examples of the present application, the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 may be independently disposed in the outer space of the rocking mechanism 10.
Illustratively, in one example of the present application, as shown in fig. 20, the left and right liquid storage containers 21 and 22 of the hydraulic drive mechanism 20 may also be disposed in the outer space of the rocking mechanism 10 and flexibly connected to the left and/or right mounting locations 102 and 103 of the rocking mechanism 10 by means such as pulleys, ropes, and hinges. Meanwhile, the adjustable weight adjustment mechanism 30 may be disposed in an external space of the rocking mechanism 10 and flexibly connected to the left mounting location 102 and/or the right mounting location 103 of the rocking mechanism 10 by means such as pulleys, ropes, and hinges, and apply a gravity change caused by weight change to the left mounting location 102 and/or the right mounting location 103.
It should be noted that, as shown in fig. 6 and 8, a solar tracking swing platform is provided according to an embodiment of the present application, which may include the hydraulic swing device 1 and the solar monitoring device 40, where the solar monitoring device 40 is controllably connected to the adjustable reconstruction mechanism 30 of the hydraulic swing device 1, so as to monitor the movement position of the sun, so that the hydraulic swing device 1 swings along with the sun. It will be appreciated that, for ease of understanding, the left and right sides of the hydrokinetic rocking device 1 will be described below as corresponding to the east and west, respectively, i.e., the hydrokinetic rocking device 1 rocking in the east-west direction; of course, in other examples of the present application, the left side and the right side of the hydraulic swing device 1 may also correspond to the south and the north, respectively, so that the hydraulic swing device 1 swings in the north-south direction, which is not described in detail in the present application.
Specifically, when the sun monitoring device 40 monitors that the sun rises (i.e., rises), the sun monitoring device 40 will control the adjustable weight mechanism 30 to decrease the weight of the left mounting location 102 and increase the weight of the right mounting location 103, so that the rocking mechanism 10 rotates from east to west; when the sun monitoring device 40 detects that the sun falls (i.e. sunset), the sun monitoring device 40 will control the adjustable weight mechanism 30 to increase the weight of the left mounting position 102 and decrease the weight of the right mounting position 103, so that the rocking mechanism 10 rotates from west to east to the left limit inclination angle, and then rotates from east to west along with the rising of the sun until the next rise.
More specifically, as shown in fig. 6, the solar monitoring device 40 may include a photo sensor 41 and a controller 42 communicatively connected to the photo sensor 41, the photo sensor 41 for sensing sunlight to emit an electrical signal; the controller 42 is configured to receive an electrical signal from the photosensor 41 to control the adjustable weight mechanism 30 to adjust the weight of the left mounting location 102 and/or the right mounting location 103 of the rocking mechanism 10. It will be appreciated that the controller 42 may be implemented as a switch control circuit.
Alternatively, as shown in fig. 7, the controller 42 of the solar monitoring device 40 may include a timing control module 421 controllably connected to the hydraulic swing device 1, the timing control module 421 including a time module 4211, a storage module 4212, and an execution module 4213; the time module 4211 returns the current time and date parameters to the execution module 4213, the storage module 4212 is used for storing a program, the program comprises the time parameters of sunrise and sunset of the preset future date and the instruction for correspondingly controlling the adjustable reconstruction mechanism 30, and the execution module 4213 runs the program in the storage module 4212; the program calls the current date and time returned by the time module 4211, compares the current date and time with the sunrise and sunset time parameters of the preset future date, and sends an electric signal to the adjustable weight balancing mechanism 30 when the current date and time are consistent with the sunrise and sunset time parameters, so that the weight balancing mechanism 30 changes the weights at the two sides of the fulcrum of the rocking mechanism 10, and the action executed by the adjustable weight balancing mechanism 30 at sunrise or sunset is similar to that of the previous example, which is not repeated in the application.
Alternatively, the photosensor 41 of the present application may be implemented as, but is not limited to, a photoresistor, a photodiode, a phototransistor, a photovoltaic panel, or the like.
It is noted that the active tracking mode of the sun-tracking rocking platform of the present application may also be implemented as a real-time control. Specifically, as shown in fig. 8, the photosensor 41 in the solar monitoring device 40 may include, but is not limited to, a left photosensor 411 disposed at the left side of the hydraulic rocking device 1 and a right photosensor 412 disposed at the right side of the hydraulic rocking device 1. The left photosensor 411 and the right photosensor 412 are communicatively connected to the controller 42. Meanwhile, the controller 42 is controllably connected to the hydraulic driving mechanism 20 of the hydraulic swing device 1, for controlling the flow valve 25 of the hydraulic driving mechanism 20 to intercept the liquid guide tube 23 to prevent the flow of the liquid W in response to the electric signal of the right photosensor 412 being weaker than the electric signal of the left photosensor 411, so that the swing mechanism 10 is maintained at a certain inclination angle; and is used for responding to the electric signal of the left photosensitive sensor 411 being weaker than the electric signal of the right photosensitive sensor 412, controlling the flow valve 25 to conduct the liquid guide tube 23 so as to allow the liquid W to flow, so that the swinging mechanism 10 rotates from east to west, and the hydraulic swinging device 1 automatically tracks the sun to rotate. It will be appreciated that the flow valve 25 may be implemented as a normally open valve to be controlled to shut off the catheter 23 and the controller 42 may be implemented as a voltage comparator.
Alternatively, as shown in fig. 6 and 8, the solar monitoring device 40 may further include a light shielding member 43 for shielding the photosensor 41 from the side, the light shielding member 43 including a left light shielding member 431 disposed at the right side of the left photosensor 411 and a right light shielding member 432 disposed at the left side of the right photosensor 412. It will be appreciated that the right side (corresponding to the west side) of the left photosensor 411 has a shadow mask and the left side (corresponding to the east side) of the right photosensor 412 has a shadow mask, while the other sides of the left photosensor 411 and the right photosensor 412 are not shadow masked.
Thus, when the sun is obliquely irradiated to the photosensor 41 from the left side, the right light shielding member 432 will block the sunlight from directly irradiating the right photosensor 412 so that the electric signal of the right photosensor 412 is weaker than the electric signal of the left photosensor 411; when the sun obliquely irradiates the photosensor 41 from the right side, the left light shielding member 431 will block the sunlight from directly irradiating the left photosensor 411 so that the electric signal of the left photosensor 411 is weaker than the electric signal of the right photosensor 412; when the sun vertically irradiates the photosensor 41, neither the left light-shielding member 431 nor the right light-shielding member 432 shields the direct sunlight so that the electric signal of the left photosensor 411 is equal to the electric signal of the right photosensor 412.
It will be appreciated that the active tracking mode of the sun-tracking rocking platform of the present application may also be implemented in other real-time control forms, such as: the angle sensor is used for obtaining the angle parameter of the hydraulic swing device 1 and comparing the angle parameter with an angle value preset by a control system in real time, and the rotation of the swing mechanism 10 is controlled to eliminate the angle deviation; or the camera is used for obtaining the position of the sun and intercepting image data for image recognition, and the rotation of the swinging mechanism 10 is controlled according to the angle deviation of the image recognition so as to eliminate the angle deviation and the like, so long as the opening and closing of the flow valve can be controlled in real time according to the sun movement and the rotation difference of the hydraulic swinging device 1 so as to track the sun swinging, and the application is not repeated. Of course, in other examples of the present application, the sun tracking swing platform may also adopt a non-real-time control mode, for example, according to the daily sun movement and the rotation difference of the hydraulic swing device 1, the opening and closing proportion amplitude of the flow valve is adjusted to adjust the rotation speed, so as to realize the optimization of tracking.
Illustratively, in one example of the present application, the flow valve 25 is a proportional flow valve. The solar monitoring device may include a photosensitive sensor disposed at a sensing position when the hydraulic rocking device is rotated from east to west to a west tilt limit angle, a position sensor, and a controller controllably connected to the flow valve. The photosensitive sensor and the position sensor are respectively and controllably connected to the controller, the photosensitive sensor outputs an electric signal to the controller when no illumination exists, and the position sensor outputs an electric signal to the controller when the hydraulic swing device rotates to the western inclination limit angle position. At the same time, the photosensitive sensor controls the signal loop of the position sensor to the controller: if the photosensitive sensor senses that light passes through, the signal loops of the position sensor and the controller are conducted; the signal loop of the position sensor and the controller is cut off if the photosensitive sensor senses no light and no current passes.
In addition, the photosensor sends an electrical signal to the controller after sunset, the controller receives the signal and sends a control command to the flow valve to increase the valve opening amplitude (such as 1%), the position sensor also sends a signal to the controller after the hydraulic swing device rotates in place, and the controller receives the signal and sends a control command to the flow valve to decrease the valve opening amplitude (such as 2%), which is 2 times the valve opening amplitude of the photosensor. When the hydraulic swing device rotates in place before sunset, the position sensor can send an electric signal to the controller, and the photosensitive sensor can send an electric signal to the controller after sunset. The two are offset, the opening amplitude of the flow valve is reduced (for example, 1%), and the rotating speed of the hydraulic swing device is reduced the next day. When the hydraulic swing device rotates in place later than sunset, the photosensitive sensor cuts off the signal loop of the position sensor and the controller after sunset, the controller can only receive the electric signal generated by the photosensitive sensor after sunset, the flow valve increases the opening amplitude of the valve, and the rotating speed of the hydraulic swing device is increased the next day.
In another example of the present application, the flow valve is a proportional flow valve. The sun monitoring device comprises a photosensitive sensor, a position sensor and a proportion control module which are arranged on the swinging mechanism. The position sensor is arranged at an induction position when the solar tracking device rotates from east to west to a west limit angle position, the photosensitive sensor and the position sensor are respectively controllably connected with the proportion control module, the proportion control module is controllably connected with the flow valve, and the proportion control module comprises a time module, a storage module and an execution module. The time module is used for returning the current time and date parameters to the execution module; the storage module is used for storing a program; the execution module is used for running the program in the storage module.
When the sun tracking system rotates from east to west to the west limit inclination angle, the position sensor senses that the hydraulic swinging device rotates in place and then sends an electric signal to the execution module, and the execution module obtains the current time parameter 2 from the time module. The execution module compares the time parameter 1 with the time parameter 2, and sends an electric signal for increasing the opening degree or reducing the opening degree (such as 1%) of the valve to the flow valve according to the time parameter 1 and the time parameter 2, so as to change the rotating speed of the hydraulic swing device. The execution module runs the program to conduct fine adjustment of increasing or decreasing on the proportional flow valve after sunset every day, so that the rotating speed of the next day is gradually optimized to the speed with the closest difference between sunset time and in-place time. It is understood that the position sensor mentioned in the present application may be a contact sensor or a non-contact sensor, wherein the non-contact sensor may be implemented by, but not limited to, photoelectric induction, electromagnetic induction, etc.
It should be noted that the light shielding member 43 of the present application may be, but not limited to, implemented as a light shielding plate or a side wall of the lever element 12, as long as the required light shielding requirement can be met, which is not described herein.
In addition, as shown in fig. 6 and 8, according to the above embodiment of the present application, the sun tracking rocking platform may further include a functional body 50, and the functional body 50 is disposed on the rocking mechanism 10 of the hydraulic rocking device 1 to be rotated by the rocking mechanism 10, so as to realize that the functional body 50 tracks the sun to rock.
Illustratively, the functional body 50 may be implemented as, but is not limited to, a solar photovoltaic panel to track the sun for generating electricity, helping to increase the efficiency of the generation; alternatively, the functional body 50 may be implemented as a plant incubator to track the sun for plant cultivation, contributing to an increase in plant growth rate. Of course, in other examples of the present application, the functional body 50 may also be implemented as a swing platform such as an industrial production device or a scientific research device, so that the sun-tracking swing platform is a swing platform required for industrial production applications and scientific research applications, which will not be described herein.
It is worth mentioning that according to another aspect of the present application, an embodiment of the present application may further provide an application device, including: the hydraulic swing device 1 is arranged in the device main body.

According to another aspect of the present application, as shown in fig. 10, one embodiment of the present application may further provide a solar tracking photovoltaic module support system 70, which may include: the support 71 is disposed on the solar tracking hydraulic rocking device 60, and the center of gravity of the solar tracking photovoltaic module support system 70 is lower than the rotation center point of the solar tracking hydraulic rocking device 60, and the support 71 is used for fixing the solar photovoltaic module 81.

According to another aspect of the present application, as shown in fig. 13, one embodiment of the present application may further provide a sun-tracking plant growing apparatus 90, which may include: the above-mentioned sun-tracking hydraulic rocking apparatus 60 and cultivation carrier 91, the said cultivation carrier 91 is set up in the said sun-tracking hydraulic rocking apparatus 60, and the centre of gravity of the said sun-tracking plant cultivation apparatus 90 is lower than the rotation centre point of the said sun-tracking hydraulic rocking apparatus 60; the cultivating carrier 91 is used for carrying a culture medium for cultivating plants. It is understood that the cultivating carrier 91 of the present application may be implemented as, but not limited to, a semi-drum container or other type of container, as long as it can be used for cultivating plants, and will not be described in detail herein.
Notably, the sun-tracking plant growing apparatus 90 can achieve uniform illumination of both sides of the plant in tracking the sun. Illustratively, the photosensitive sensor is disposed on the rocking mechanism and is controllably connected to the timing control module; the timing control module comprises a time module, a storage module and an execution module; the time module returns the current time to the execution module in real time, the storage module is used for storing a program, the program comprises a preset time delay time length and a corresponding instruction for controlling the flow valve, and the execution module runs the program in the storage module to control the opening and closing of the flow valve.
Specifically, the photosensitive sensor sends an electric signal to the execution module when sensing sunrise, and the real-time returned by the execution module when receiving the return of the time module is sunrise time. The sunrise time and the preset delay time length X in the storage module are added to obtain a first delay control time point A, the sunrise time and the preset delay time length Y in the storage module are added to obtain a second delay control time point B, and the sunrise time and the preset delay time length Z in the storage module are added to obtain a third delay control time point C. When the real-time returned by the time module is consistent with the time delay control time point A, the execution module sends a control instruction to the flow valve to conduct the liquid guide pipe so as to allow the liquid W to flow and enable the device to rotate. When the execution module receives the consistency of the real-time returned by the time module and the time delay control time point B, a control instruction is sent to the flow valve to intercept the liquid guide pipe so as to prevent the liquid W from flowing and stopping the rotation of the device. When the execution module receives the consistency of the real-time returned by the time module and the delay control time point C, a control instruction is sent to the flow valve to conduct the liquid guide pipe so as to allow the liquid W to flow and enable the device to rotate.
It will be appreciated that the time delay control point a is the time when the sun rises out to an optimal angle of incidence on the east side of the plant, from which point a the device starts to track the sun in rotation. The time delay control time point B is the time when the device is in a horizontal posture, the plant is in a vertical posture, the sun is shot to the plant from the east side at an optimal incidence angle, rotation is stopped at the time point, and the sun is waited to be transformed to the west side incidence angle beyond the top of the plant. The time delay control time point C is the time that the sun has been directed to the plant from the west over the top of the plant at an optimal angle of incidence, at which time the device starts to track the sun a second time. The setting of the time delay duration X, Y, Z needs to take into account the speed of rotation of the hydraulic swing device 1, and the flow valve can adjust the speed of rotation by using a proportional valve.
In the above example, we have calculated the time delay control point B when the hydraulic rocking device is in the horizontal posture. Alternatively, in other examples of the present application, we can use an attitude sensor to sense that the hydraulic turning device is in a horizontal attitude instead of timing control at time point B of the delay control. The attitude sensor is controllably connected with the timing control module, and sends an electric signal to the timing control module when sensing that the hydraulic swing device is in a horizontal attitude, and the hydraulic swing device is controlled to stop rotating, and the hydraulic swing device is restarted to a time point C of delay control.
