The existing swing mechanism driven by a motor often has the problems of complex mechanical structure, large transmission loss, serious mechanical abrasion, short service life of the motor and the like, so that the reliability of long-term use is poor. Therefore, the present application provides a hydraulic swing device and an application thereof, which can achieve a swing effect by using hydraulic driving to solve various problems caused by motor driving.
Specifically, referring to fig. 1 to 5, an embodiment of the present invention provides a hydraulic swing apparatus 1 for realizing swing by flowing liquid W. The hydraulic rocking device 1 may include a rocking mechanism 10, a hydraulic drive mechanism 20, and an adjustable counterweight mechanism 30. The rocking mechanism 10 has a centre of rotation point 101, a left mounting location 102 and a right mounting location 103. The hydraulic drive mechanism 20 may include a left reservoir 21 mounted to the left mounting location 102, a right reservoir 22 mounted to the right mounting location 103, and a liquid conduit 23 communicating with the left reservoir 21 and the right reservoir 22, wherein the left reservoir 21 and the right reservoir 22 are respectively used for storing liquid W. The adjustable weight mechanism 30 is controlled to adjust the weight of the left mounting position 102 and/or the right mounting position 103 of the swing mechanism 10 to change the tilt angle of the swing mechanism 10 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 under the action of the self gravity, and the swing mechanism 10 swings to different tilt angles along with the flow of the liquid W; wherein the center of gravity of the hydraulic swing device 1 is lower than the rotational center point 101 of the swing mechanism 10.
More specifically, the left mounting location 102 of the swing mechanism 10 is located on the left side of the fulcrum of the swing mechanism 10, and the right mounting location 103 of the swing mechanism 10 is located on the right side of the fulcrum of the swing mechanism 10.
Exemplarily, in an example of the present application, as shown in fig. 1 to 3, the swing mechanism 10 may be, but is not limited to be, implemented as a lever mechanism 100, the lever mechanism 100 may include a fulcrum element 11 and a lever element 12 rotatably disposed at the fulcrum element 11, and the lever element 12 may include a left cantilever 121 extending leftward from the fulcrum element 11 and a right cantilever 122 extending rightward from the fulcrum element 11. The hydraulic drive mechanism 20 may include a left reservoir 21 suspended from the left suspension arm 121, a right reservoir 22 suspended from the right suspension arm 122, and a catheter 23 communicating with the left reservoir 21 and the right reservoir 22, wherein the left reservoir 21 and the right reservoir 22 are respectively used for storing liquid W, so that the center of gravity of the lever is lower than the fulcrum of the lever. The adjustable weight mechanism 30 is controlled to adjust the weight of the left suspension arm 121 and/or the right suspension arm 122 of the lever element 12 to change the tilt angle of the lever element 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 under the action of its own gravity, so that the lever element 12 swings to different tilt angles along with the flow of the liquid W.
It will be understood that references to a fulcrum point of the lever herein may refer to the point of support provided by the fulcrum element 11 for the lever element 12; the lever center of gravity referred to herein may be the combined center of gravity of the lever element 12 and the hydraulic drive mechanism 20. In addition, the fulcrum element 11 of the lever mechanism 100 of the present application may provide a center point of rotation 101 of the rocking mechanism 10; the left suspension arm 121 and the right suspension arm 122 in the lever element 12 of the lever mechanism 100 can provide the left mounting position 102 and the right mounting position 103 of the swing mechanism 10, respectively.
It is worth noting that according to the mechanical principle of the lever, for the lever with the gravity center lower than the fulcrum, after the balance weights on the left side and the right side of the lever are adjusted, the lever can rotate around the fulcrum until the lever rotates to a certain inclination angle to achieve the new lever balance adjustment; that is, after the left and right balance weights of the lever are adjusted, the lever is rotated and stably maintained in a moment-balanced inclined posture until the left and right balance weights of the lever are adjusted again to rotate again to a new inclined posture. Therefore, the present application designs the hydraulic swing device 1 using the principle to achieve the swing effect of the lever by using hydraulic driving, i.e., to adjust the tilting angle of the lever member 12 by using the change of the weight difference of the liquid W in the left liquid reservoir 21 and the right liquid reservoir 22.
Alternatively, the liquid W mentioned in the present application may not be limited to being embodied as water; of course, in other examples of the present application, the liquid W mentioned in the present application may also be implemented as a fluid such as a solution or an organic solvent, as long as the liquid W can flow between the left liquid storage container 21 and the right liquid storage container 22 through the liquid guide tube 23, and the description of the present application is omitted.
According to the above 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 swing mechanism 10 rotates clockwise under the effect of the weight moment to raise the left reservoir 21 and lower 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; when the adjustable counterbalance mechanism 30 is controlled to increase the counterbalance of the left mounting location 102 and/or decrease the counterbalance of the right mounting location 103, the swing mechanism 10 rotates counterclockwise under the moment of the counterbalance 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 counterbalance mechanism 30 is controlled to decrease the counterbalance of the left suspension arm 121 and/or increase the counterbalance of the right suspension arm 122, the lever member 12 rotates clockwise under the effect of the counterbalance 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 flows 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, so that the lever element 12 further rotates clockwise to a different tilt angle along with the flow of the liquid W, until after the flow of the liquid W is stopped, the lever element 12 rotates clockwise to a new tilt angle to achieve a new lever balance condition.
Similarly, as shown in fig. 5, when the adjustable weight mechanism 30 is controlled to increase the weight of the left suspension arm 121 and/or decrease the weight of the right suspension arm 122, the lever element 12 will rotate counterclockwise under the effect of the weight moment to depress the left liquid storage container 21 and raise the right liquid storage container 22, so 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 flows 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, so that the lever element 12 will further rotate counterclockwise to different tilt angles along with the flow of the liquid W, until after the flow of the liquid W is stopped, the lever element 12 rotates counterclockwise to a new tilt angle to achieve a new lever balance condition.
It should be noted that the tilting angle of the lever 12 of the present application is determined by the weight difference between the left suspension arm 121 and the right suspension arm 122, and the maximum weight moment difference between the left and right sides can be calculated according to the maximum tilting angle to be achieved, so as to calculate the weight of the liquid required to be stored in the left liquid container 21 and the right liquid container 22. It will be appreciated that neither the left reservoir 21 nor the right reservoir 22 has a volume less than the volume of liquid required to be stored.
Alternatively, as shown in fig. 2 and 3, one end of the liquid guiding tube 23 is connected to the bottom opening of the left liquid storage container 21, and the other end of the liquid guiding 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 liquid storage container 21 and the right liquid storage container 22 can smoothly flow through the liquid guide tube 23 under the action of self gravity, the left liquid storage container 21 and the right liquid storage container 22 of the present application may further be provided with a top opening to balance the air pressure difference between the left liquid storage container 21 and the right liquid storage container 22.
Optionally, as shown in fig. 2 and fig. 3, the hydraulic driving mechanism 20 of the present application may further include a gas guiding tube 24, one end of the gas guiding tube 24 is connected to the top opening of the left liquid storage container 21, and the other end of the gas guiding tube 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, which 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 guiding tube 23.
It is understood that in other examples of the present application, the hydraulic drive mechanism 20 of the present application may include overfill prevention devices disposed in the left reservoir 21 and the right reservoir 22. For example, the overfill prevention device of the present application can be, but is not limited to being, implemented as a buoyancy valve for closing the top opening when the liquid level in the container rises to a predetermined height; or the bottom opening is closed when the liquid level in the container drops to a predetermined height, 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 also be achieved.
Alternatively, as shown in fig. 2 and 3, the left liquid storage container 21 and the right liquid storage container 22 are flexibly suspended from the left suspension arm 121 and the right suspension arm 122, respectively, so as to facilitate the liquid level difference measurement while reducing the occupied space. It is understood that the flexible connections referred to herein may be implemented, but are not limited to, as hinged or corded connections; 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 suspension arm 121 and the right suspension arm 122, respectively.
It should be noted that the installation position of the liquid storage container on the swing mechanism 10 needs to be selected according to the self structure and the external space conditions of the hydraulic swing device 1; the force arm of the hydraulic driving mechanism 20 on the lever element 12 will be changed due to different installation positions, and the shorter the force arm, the larger the counterweight weight that the hydraulic driving mechanism 20 needs to exert, i.e. the more the stored liquid W needs to be; therefore, as shown in fig. 2 and 3, the left liquid container 21 and the right liquid 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 increase the force applying arm to the maximum extent and reduce the required amount of liquid. It will be appreciated that the free ends of the left boom 121 and the right boom 122 now serve as the left mounting location 102 and the right mounting location 103, respectively.
Optionally, the catheter 23 and/or the airway tube 24 may be implemented as a hose to avoid disturbing the natural hang-up of the left reservoir 21 and the right reservoir 22 when the lever element 12 is rotated, in order to simplify the mechanical analysis. It is understood that in other examples of the present application, the catheter 23 and/or the airway tube 24 may also be implemented as a rigid tube, which is not described in detail herein.
It is noted that the left reservoir 21 and the right reservoir 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 reservoir 21 and the right reservoir 22 may also be implemented as containers having different shapes and/or capacities, which will not be described in detail herein.
Alternatively, the left reservoir 21 and the right reservoir 22 of the present application may be implemented as cylindrical containers, such as drums and the like. Of course, in other examples of the present application, the left reservoir 21 and the right reservoir 22 may also be implemented as ball-type containers or other types of containers, which will not be described in detail herein.
It should be noted that when the left and right liquid reservoirs 21 and 22 store different weights of liquid W, respectively, the lever member 12 will satisfy the lever balance condition at a certain tilt angle to be stably maintained at the tilt angle; and as the liquid W flows between the left liquid reservoir 21 and the right liquid reservoir 22 through the liquid guide tube 23, the lever member 12 will rotate to different inclination angles to satisfy the lever balance condition; at the same time, the rotation speed of the lever member 12 depends on the flow rate of the liquid W through the liquid guide tube 23, that is, the greater the flow rate of the liquid W, the faster the rotation 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 guiding tube 23, and thus the time required for the lever member 12 to rotate from a certain inclination angle to another inclination angle, so as to meet the specific application requirements.
Alternatively, as shown in fig. 4 and 5, the hydraulic swing device 1 of the present application may include a flow valve 25 disposed on the liquid guide tube 23, wherein the flow valve 25 is controlled to conduct or intercept the liquid guide tube 23, so as to allow or prevent the liquid flowing in the liquid guide tube 23 to control the swing mechanism 10 to start or stop rotating.
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 tilt angle so that there is a level difference between the left liquid reservoir 21 and the right liquid reservoir 22; and when the flow valve 25 is controlled to conduct the liquid guide tube 23, the liquid guide tube 23 is used for making the liquid W stored in the left liquid storage container 21 and the right liquid storage container 22 flow under the action of the liquid level difference, so that the lever element 12 automatically rotates counterclockwise or clockwise.
It is noted that the flow valve 25 can be, but is not limited to, implemented as a solenoid valve in order to automatically control the switching 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 catheter 23 to continuously adjust the flow rate of the liquid passing through the catheter 23 to control the rotation speed of the swing mechanism 10. In other words, the flow valve 25 also has a flow rate regulation function; that is, the flow valve 25 is further used to adjust the flow area of the liquid guiding tube 23, so as to adjust the flow rate of the liquid W stored in the left liquid storage container 21 and the right liquid storage container 22 through the liquid guiding tube 23, and further adjust and control the rotation speed of the swing mechanism 10, so as to meet the rotation time requirement in different seasons, for example, in summer, a faster rotation speed is required in winter, so as to shorten the rotation time, and facilitate better tracking of the sun for swing.
It is noted that the lever element 12 in the hydraulic swing device 1 of the present application is adapted to swing between a left limit tilting angle and a right limit tilting angle, wherein when the lever element 12 is rotated to the left limit tilting angle or the right limit tilting 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 cannot flow through the liquid guiding tube 23 due to no liquid level difference, so as to be stably maintained at the left limit tilting angle or the right limit tilting angle. It will be understood that the left extreme tilt angle referred to in this application refers to the maximum tilt angle at which the lever member 12 is rotated counterclockwise; accordingly, the right limit inclination angle refers to the maximum inclination angle at which the lever member 12 is rotated clockwise.
Alternatively, as shown in fig. 2 and 3, under the precondition that the liquid level in the left liquid storage container 21 is equal to 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 while being stably maintained at the left limit inclination angle or the right limit inclination angle, the lever balance condition can be broken only by applying a very small counterweight difference through the adjustable counterweight mechanism 30, 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 and achieving the effect of four-two jacks.
Preferably, as shown in FIG. 2, when the lever member 12 is rotated counterclockwise to the left extreme tilt angle, the bottom wall of the right reservoir 22 is flush with the liquid level in the left reservoir 21, so that the liquid W stored in the right reservoir 22 completely flows into the left reservoir 21; as shown in FIG. 3, when the lever member 12 is rotated clockwise to the right extreme tilt angle, the bottom wall of the left reservoir 21 is flush with the liquid level in the right reservoir 22, so that the liquid W stored in the left reservoir 21 can completely flow into the right reservoir 22. Thus, the total amount of the liquid W stored in the left liquid reservoir 21 and the right liquid reservoir 22 is minimized, but sufficient to drive the lever member 12 to swing between the left limit tilting angle and the right limit tilting angle.
More preferably, as shown in fig. 2, when the lever member 12 is rotated counterclockwise to the left extreme inclined angle, the bottom wall of the right reservoir 22 is flush with the top wall of the left reservoir 21, so that the liquid W stored in the right reservoir 22 completely flows into the left reservoir 21 and just fills the left reservoir 21; as shown in FIG. 3, when the lever member 12 is rotated clockwise to the right extreme inclined angle, 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 and just fills the right liquid storage container 22. Thus, the left reservoir 21 and the right reservoir 22 have the smallest volume to just contain the fluid W that provides the hydraulic drive to fully utilize the reservoir volume.
Illustratively, as shown in fig. 1, when the lever element 12 is in a horizontal posture, the left suspension arm 121 of the lever element 12 extends obliquely left and downward from the fulcrum element 11, and the right suspension arm 122 extends obliquely right and downward from the fulcrum element 11, so as to ensure that the center of gravity of the lever element 12 is located below the fulcrum point of the fulcrum element 11.
Assuming that the left and right overall masses of the lever (i.e., the sum of the left and right masses of the lever element 12, the hydraulic drive mechanism 20, and the adjustable counterweight mechanism 30) are respectively concentrated at the free ends of the left boom 121 and the right boom 122, e.g., the left and right overall masses of the lever are both 7.5Kg; the lengths of the left cantilever 121 and the right cantilever 122 are both 1 meter; the included angle between the left suspension arm 121 and the right suspension arm 122 is 170 °, that is, when the lever element 12 is in a horizontal posture, the included angles between the left suspension arm 121 and the right suspension arm 122 and the horizontal plane are both 5 °; the left and right extreme inclination angles of the lever element 12 are both 30 °.
Thus, when the lever member 12 is rotated counterclockwise to the left extreme tilt angle, the angle between the left cantilever 121 and the horizontal plane of the lever member 12 is 35 °, and the angle between the right cantilever 122 and the horizontal plane is 25 °; at this point, the lever element 12 has a left moment arm of 1 × cos35 ° m and a right moment arm of 1 × cos25 ° m; in order to secure the lever element 12 inThe left extreme inclination angle satisfies the lever balance condition (i.e. moment balance), and the mass m of the liquid stored in the left liquid storage container 21 at this moment 1 Needs to satisfy (7.5+m 1 ) G × 1 × cos35 ° =7.5 × g × 1 × cos25 °, that is, the mass m of the liquid stored in the left reservoir 21 1 ＝0.798Kg。
Similarly, when the lever member 12 is rotated clockwise to the left extreme tilt 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 point, the right moment arm of the lever element 12 is 1 × cos35 ° m, and the left moment arm is 1 × cos25 ° m; to ensure that the lever element 12 satisfies the lever balance condition (i.e., moment balance) at the right extreme tilt 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 × g × 1 × cos25 °, that is, the mass m of the liquid stored in the right reservoir 22 2 ＝0.798Kg。
In summary, in the above example of the present application, the total amount of liquid stored in the left liquid storage container 21 and the right liquid storage container 22 is at least 0.798Kg, which can satisfy the hydraulic driving requirement of the lever element 12 swinging between 30 ° counterclockwise and 30 ° clockwise. In addition, the height of each of the left reservoir 21 and the right reservoir 22 of the present application is implemented as 1 × sin35 ° +1 × sin25 ° =0.9962 meters. Since 0.798Kg of water is equivalent to 798mL of water, the left reservoir 21 and the right reservoir 22 of the present application each have a capacity of 798mL, so that for every gram of water flowing out of the left reservoir 21, the liquid level in the left reservoir 21 will drop by 1.25mm, and correspondingly the liquid level in the right reservoir 22 will rise by 1.25mm.
It is noted that the adjustable weight mechanism 30 of the present application can be controlled to apply 0.05Kg of weight to the free end of the left arm 121 or the right arm 122 to break the original lever balance condition of the lever element 12, so that the lever element 12 automatically rotates to form a liquid level difference between the left liquid container 21 and the right liquid container 22. And the following can be known through measurement and calculation: when the adjustable weight mechanism 30 applies 0.05Kg of weight to the free end of the right cantilever 122, the liquid level in the left liquid storage container 21 is always higher than the liquid level in the right liquid storage container 22 during the rotation of the lever element 12 from the left limit inclined angle to the right limit inclined 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 adjustable weight mechanism 30 applies 0.05Kg of weight to the free end of the left suspension arm 121, 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 rotation of the lever element 12 from the right limit inclined angle to the left limit inclined angle, so as to ensure that the liquid W can completely flow from the right liquid storage container 22 to the left liquid storage container 21.
It can be understood that the adjustable counterweight mechanism 30 of the present application only needs to apply 0.05Kg of counterweight as the starting force, and the hydraulic driving mechanism 20 can be used to drive the 15Kg lever to swing between the left limit inclination angle and the right limit inclination angle, so as to achieve the effect of increasing in size. In addition, the weight of 0.05Kg applied by the adjustable weight mechanism 30 of the present application is only an example, and in fact, the weight which breaks the lever balance condition and provides the starting force may be less than 0.05Kg, and the present application is not described in detail herein.
It should be noted that, as shown in fig. 1 to 5, the adjustable counterweight mechanism 30 of the present application includes a left counterweight container 31 and/or a right counterweight container 32 provided in the swing mechanism 10, and the left counterweight container 31 and/or the right counterweight container 32 are respectively used for being filled with or drained of liquid with a predetermined mass, so as to change the center of gravity of the hydraulic swing device 1 to start the swing mechanism 10 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 disposed on the left suspension arm 121 and a right weight container 32 disposed on the right suspension arm 122, the left weight container 31 and the right weight container 32 being respectively used for being filled with or discharged with a predetermined mass of liquid W to break a lever balance condition of the lever element 12 at the left limit inclination angle and the right limit inclination angle, so that the lever element 12 rotates to always form a liquid level difference between the left liquid reservoir 21 and the right liquid reservoir 22. It is understood that the predetermined mass mentioned in the present application may be, but is not limited to, implemented as a counterweight mass capable of breaking the lever balance condition of the lever member 12 at the left and right limit inclination angles to rotate the lever member 12 to always form a liquid level difference, such as 0.05Kg in the above example.
Thus, as shown in fig. 4, when the liquid W is discharged from the left container 31 and the liquid W is injected into the right container 32, the lever balance condition of the lever element 12 at the left limit tilting angle is broken, and the lever element 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, so that the lever element 12 automatically rotates from the left limit tilting angle to the right limit tilting angle as the liquid W flows from the left liquid storage container 21 into the right liquid storage container 22. Similarly, 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 element 12 at the right limit tilting angle is broken, and the lever element 12 rotates counterclockwise to make the liquid level in the right liquid reservoir 22 higher than the liquid level in the left liquid reservoir 21, so that the lever element 12 automatically rotates from the right limit tilting angle to the left limit tilting angle as the liquid W flows from the right liquid reservoir 22 to the left liquid reservoir 21.
Alternatively, the capacity of the left counterweight container 31 and the right counterweight container 32 of the present application are both equal to the volume of the predetermined mass of water, so that the left counterweight container 31 and the right counterweight container 32 only need to be filled or emptied of water, respectively, to achieve the effect of initiating the hydraulic drive.
Preferably, as shown in fig. 2 and 3, the left weight container 31 is fixed to the left liquid storage container 21, so that the left weight container 31 is suspended from the free end of the left suspension arm 121; the right weight container 32 is fixedly attached to the right reservoir 22 such that the right weight container 32 is suspended from the free end of the right suspension arm 122.
It can be understood that, the left counterweight container 31 and the right counterweight container 32 of the present application can be, but are not limited to, filled with water and drained with an automatic control mode using an electromagnetic valve, and at this time, the filling with water and the draining with water can be automatically controlled only by additionally installing a water level switch or a timing switch. Of course, in another example of the present application, the adjustable weight mechanism 30 may only include the left weight container 31 (the right weight container 32), and at this time, the capacity of the left weight container 31 (the right weight container 32) is twice of the water volume of the predetermined mass, and the difference between the right side (left side) overall mass and the left side (right side) overall mass of the lever is equal to the predetermined mass, so that the lever element 12 can be automatically rotated from the right limit inclination angle to the left limit inclination angle only by filling the left weight container 31 (the right weight container 32) with water; or emptying the left counterweight container 31 (the right counterweight container 32), the lever element 12 can be activated to automatically rotate from the left extreme inclination angle to the right extreme inclination angle.
It is noted that in other examples of the present application, the adjustable counterweight mechanism 30 can also be implemented as other types of reciprocating mechanisms that are controlled to drive a counterweight block to reciprocate between the left mounting location 102 and the right mounting location 103 to break the lever balance condition of the rocking mechanism 10 at the left and right limit inclination angles.
Illustratively, the adjustable counterweight mechanism 30 may also include a reciprocating mechanism and a counterweight disposed on the swing mechanism 10, the reciprocating mechanism being controlled to move the counterweight left or right to change the center of gravity of the hydraulic swing device 1 to start the swing 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 counterweight to move back and forth on the left and right sides of the lever element 12 to break the lever balance condition of the lever element 12 at the left and right limit inclination angles, so that the lever element 12 rotates to always form a liquid level difference between the left liquid storage container 21 and the right liquid storage container 22. It is understood that the reciprocating mechanism can be implemented as a transmission device consisting of a motor and a gear, and the counterweight block is pulled to move left and right along the lever element by a chain, such as a stepping motor is used for controlling the reciprocating motion of the counterweight block, or a common motor is used for controlling the reciprocating motion of the counterweight block in cooperation with a limiting mechanism, and the like; this reciprocating mechanism can also be implemented as electromagnetic drive mechanism to the drive rolls armature and moves about in the pipeline, if uses electromagnetic suction device to attract armature reciprocating motion or uses electromagnetic spring device to launch armature and carry out reciprocating motion, and this application is no longer repeated to this.
It is to be noted that, in the above example of the present application, the fulcrum of the swing mechanism 10 in the hydraulic swing device 1 is implemented as the rotation center point 101, so that the fulcrum position is not changed when the swing mechanism 10 rotates, that is, the hydraulic swing device 1 rotates around the fulcrum of the swing mechanism 10. However, in other examples of the present application, the swing mechanism 10 may be implemented as a mechanism having a tumbler structure such as a half-drum mechanism, and the required side-to-side swing can be achieved by the hydraulic drive mechanism 20 and the adjustable weight mechanism 30 of the present application as long as the overall center of gravity 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 reciprocally rollable half roller mechanism 100' whose fulcrum and center point of rotation are not one point. Thus, 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, in the fluid dynamic rocking device 1, when the force is balanced and the posture is stabilized without the influence of the external force, the fulcrum position of the half drum mechanism 100' is set as the fulcrum, and the left mounting position 102 and the right mounting position 103 are provided on the left and right sides of the fulcrum accordingly. In addition, in the rocking mechanism 10, the center of gravity and the fulcrum are on the same vertical line and the center of gravity is below the center of rotation 101 in the force balance stable posture. It is understood that this example of the present application still enables the center of gravity of the rocking mechanism 10 to be always below the center point 101 of rotation when the rolling rotation of the left-right reciprocating motion is achieved by the hydraulic drive mechanism 20 and the adjustable weight mechanism 30.
Alternatively, as shown in fig. 15, the half drum mechanism 100' may roll on a horizontal support surface; alternatively, as shown in fig. 12, the half-roller mechanism 100' may roll on an arc-shaped bearing surface, so as to add balls or rollers between the two, which is beneficial to reduce rolling friction.
It should be noted that the installation positions of the hydraulic driving mechanism 20 and the adjustable weight mechanism 30 on the rocking mechanism 10 need to be selected according to the own structure and the 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 both disposed in the internal space of the rocking mechanism 10, they are only examples, 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 external space of the rocking mechanism 10.
Illustratively, in an example of the present application, as shown in fig. 20, the left reservoir 21 and the right reservoir 22 of the hydraulic driving mechanism 20 may also be disposed at an external space of the swing mechanism 10 and flexibly connected to the left mounting position 102 and/or the right mounting position 103 of the swing mechanism 10 by means of a pulley, a rope, a hinge, and the like. Meanwhile, the adjustable counterweight mechanism 30 can also be arranged in the external space of the rocking mechanism 10 and flexibly connected to the left mounting position 102 and/or the right mounting position 103 of the rocking mechanism 10 by means of a pulley, a rope, a hinge and the like, and the gravity change caused by counterweight change is acted on the left mounting position 102 and/or the right mounting position 103.
It is worth mentioning that as shown in fig. 6 and 8, according to an embodiment of the present application, a solar tracking swing platform is provided, which may include the above-mentioned hydraulic swing device 1 and a solar monitoring device 40, wherein the solar monitoring device 40 is controllably connected to the adjustable weight mechanism 30 of the hydraulic swing device 1 for monitoring the movement position of the sun, so that the hydraulic swing device 1 follows the swing rotation of the sun. It is to be understood that, for the sake of convenience of understanding, the following description will be made with the left and right sides of the hydraulic swing device 1 corresponding to east and west, respectively, i.e., the hydraulic swing device 1 swings 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 herein.
Specifically, when the sun monitoring device 40 detects 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 swing mechanism 10 rotates from east to west; when the sun monitoring device 40 detects that the sun falls (i.e., falls), the sun monitoring device 40 controls 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 swing mechanism 10 rotates from west to east to the left limit inclination angle until the next day rises and then rotates from east to west along with the rise of the sun.
More specifically, as shown in fig. 6, the sun monitoring device 40 may include a photosensor 41 and a controller 42 communicably connected to the photosensor 41, the photosensor 41 being for sensing sunlight to emit an electric signal; the controller 42 is used for receiving the electrical signal from the photosensitive sensor 41 to control the adjustable weight mechanism 30 to adjust the weight of the left mounting position 102 and/or the right mounting position 103 of the swing 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 apparatus 40 may include a timing control module 421 controllably connected to the hydraulic swing apparatus 1, wherein the timing control module 421 includes 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 comprising preset time parameters of sunrise and sunset on future dates and instructions for controlling the adjustable weighting mechanism 30 accordingly, 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 electrical signal to the adjustable counterweight mechanism 30 to change the counterweights at two sides of the pivot of the rocking mechanism 10 when the current date and time parameters are consistent with the sunrise and sunset time parameters, and the action executed by the adjustable counterweight mechanism 30 at sunrise or sunset is similar to the previous example, which is not described in detail herein.
Alternatively, the photosensor 41 of the present application may be implemented as, but not limited to, a photoresistor, a photodiode, a phototriode, a photovoltaic panel, or the like.
It is noted that the active tracking mode of the sun-tracking rocking platform of the present application can also be implemented as a real-time control mode. Specifically, as shown in fig. 8, the photosensor 41 in the sun monitoring device 40 may include, but is not limited to, a left photosensor 411 disposed on the left side of the hydraulic swing device 1 and a right photosensor 412 disposed on the right side of the hydraulic swing device 1. The left photosensor 411 and the right photosensor 412 are communicatively connected to the controller 42. At the same time, the controller 42 is controllably connected to the hydraulic driving mechanism 20 of the hydraulic swing device 1, and is used for controlling the flow valve 25 of the hydraulic driving mechanism 20 to cut off the liquid guide pipe 23 in response to the electric signal of the right photosensor 412 being weaker than the electric signal of the left photosensor 411, so as to stop the flow of the liquid W, and thus, the swing mechanism 10 is kept at a certain inclination angle; and is used for controlling the flow valve 25 to conduct the liquid guide pipe 23 in response to the electric signal of the left photosensitive sensor 411 being weaker than the electric signal of the right photosensitive sensor 412, so as to allow the liquid W to flow, so that the swing mechanism 10 rotates from east to west, thereby realizing that the hydraulic swing 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.
Optionally, as shown in fig. 6 and 8, the sun monitoring device 40 may further include a light shielding member 43 for shielding the photosensor 41 from the side, and the light shielding member 43 includes a left light shielding member 431 disposed on the right side of the left photosensor 411 and a right light shielding member 432 disposed on the left side of the right photosensor 412. It will be appreciated that there is a shadow mask on the right side (corresponding to the west) of the left photosensor 411 and a shadow mask on the left side (corresponding to the east) of the right photosensor 412, while there is no shadow mask on the other sides of the left photosensor 411 and the right photosensor 412.
Thus, when the sun obliquely irradiates the photosensor 41 from the left side, the right shade 432 will block the sunlight from directly irradiating the right photosensor 412, so that the electrical signal of the right photosensor 412 is weaker than the electrical 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 electrical signal of the left photosensor 411 is weaker than the electrical signal of the right photosensor 412; when the sun vertically irradiates the photosensor 41, neither the left shade 431 nor the right shade 432 shades the direct sunlight, so that the electrical signal of the left photosensor 411 is equal to the electrical signal of the right photosensor 412.
It is understood that the active tracking mode of the sun-tracking rocking platform of the present application can 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, the angle parameter is compared with the angle value preset by the control system in real time, and the swing mechanism 10 is controlled to rotate so as to eliminate the angle deviation; or the camera is used for obtaining the position of the sun and capturing image data for image recognition, the rotation of the swing mechanism 10 is controlled to eliminate the angle deviation and the like according to the angle deviation of the image recognition, and the opening and closing of the flow valve can be controlled in real time according to the rotation difference of the sun movement and the hydraulic swing device 1 so as to track the sun swing, so that the details are not repeated in the application. Of course, in other examples of the present application, the sun tracking swing platform may also adopt a non-real-time control form, such as adjusting the rotation speed by adjusting the opening and closing proportional amplitude of the flow valve according to the difference between the sun movement and the rotation of the hydraulic swing device 1 every day, so as to achieve the optimization of the 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 light sensitive sensor positioned to sense rotation of the hydraulic swing from east to west to a west side inclination 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 the photosensitive sensor is not illuminated, and the position sensor outputs an electric signal to the controller when the hydraulic swing device rotates to the west-side inclined limit angle position. At the same time, the light-sensitive sensor controls the signal circuit of the position sensor to the controller: if the photosensitive sensor senses that the light passes through the current, the signal loops of the position sensor and the controller are conducted; the signal loop of the position sensor and the controller is interrupted if the light sensitive sensor senses no light and no current is passing.
In addition, the photosensitive sensor sends an electrical signal to the controller after sunset, the controller sends a control command to the flow valve to increase the valve opening amplitude (e.g., 1%) when receiving the signal, the position sensor also sends a signal to the controller when the hydraulic swing device rotates to a certain position, and the controller sends a control command to the flow valve to decrease the valve opening amplitude (e.g., 2%) when receiving the signal, wherein the amplitude is 2 times the valve opening amplitude of the photosensitive sensor. When the hydraulic swing device rotates in place before sunset, the position sensor sends an electric signal to the controller, and the photosensitive sensor also sends an electric signal to the controller after sunset. And the flow valve reduces the opening amplitude (such as 1%), and the hydraulic swing device slows down the next day. When the hydraulic swing device rotates in place later than sunset, the photosensitive sensor cuts off signal loops of the position sensor and the controller after sunset, the controller can only receive electric signals generated by the photosensitive sensor after sunset, the flow valve increases the opening range of the valve, and the rotating speed of the hydraulic swing device is accelerated next day.
In another example of the present application, the flow valve is a proportional flow valve. The solar monitoring device comprises a photosensitive sensor, a position sensor and a proportional control module which are arranged on the swing mechanism. The position sensor is arranged at a sensing position when the solar tracking device rotates to a west limit angle position from east to west, the photosensitive sensor and the position sensor are respectively and controllably connected to the proportional control module, the proportional control module is controllably connected to the flow valve, and the proportional 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 programs; the execution module is used for operating 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 swing device rotates to the position and then sends an electric signal to the execution module, and the execution module obtains a 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 decreasing the opening degree (such as 1%) of the valve to the flow valve according to the time parameter 1 and the time parameter 2 when the time parameter 1 is too early or too late, so as to change the rotating speed of the hydraulic swing device. The executive module runs the program after sunset every day and conducts fine adjustment of increasing or decreasing on the proportional flow valve, so that the rotating speed of the next day is gradually optimized to the speed which is closest to the difference between the sunset time and the rotation-in-place time. It is understood that the position sensor mentioned in the present application may be a contact sensor, and may also be a non-contact sensor, wherein the non-contact sensor may be implemented by, but is not limited to, a photoelectric sensing, an electromagnetic sensing, etc.
It should be noted that the light shielding member 43 of the present application can be implemented as, but not limited to, a light shielding plate or a sidewall of the lever member 12, as long as the required light shielding requirement can be met, and the description thereof is omitted herein.

According to another aspect of the present application, as shown in fig. 13, an embodiment of the present application may further provide a sun-tracking plant growing apparatus 90, which may include: the above-mentioned sun-tracking hydraulic swing device 60 and the cultivation carrier 91, the cultivation carrier 91 is provided to the sun-tracking hydraulic swing device 60, and the center of gravity of the sun-tracking plant cultivation device 90 is lower than the rotation center point of the sun-tracking hydraulic swing device 60; the cultivation carrier 91 is used for carrying a culture medium to grow plants. It is understood that the cultivation carrier 91 of the present application may be, but is not limited to, implemented as a semi-drum-shaped container or other type of container as long as it can be used to cultivate plants, which will not be described herein again.
It is noted that the sun-tracking plant growing apparatus 90 can achieve uniform illumination of both sides of a plant in tracking the sun. Illustratively, the photosensitive sensor is arranged on the swinging mechanism and is controllably connected with 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 delay time and a corresponding instruction for controlling the flow valve, and the execution module operates 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 that the execution module receives the time returned by the time module is the sunrise time. The sunrise time and the delay time length X preset in the storage module are added to obtain a first delay control time point A, the sunrise time and the delay time length Y preset in the storage module are added to obtain a second delay control time point B, and the sunrise time and the delay time length Z preset in the storage module are added to obtain a third delay control time point C. When the execution module receives the real-time returned by the time module and the time delay control time point A are consistent, the execution module sends a control instruction to the flow valve, and the liquid guide pipe is conducted to allow the liquid W to flow and enable the device to rotate. When the execution module receives that the real-time returned by the time module is consistent with the delay control time point B, the execution module sends a control instruction to the flow valve to cut off the catheter so as to prevent the liquid W flow stopping device from rotating. When the real-time returned by the time module is consistent with the delay control time point C, the execution module sends a control command to the flow valve, and conducts the liquid guide pipe to allow the liquid W to flow and rotate the device.
It can be understood that the delay control time point a is the time when the sunrise reaches the optimum incident angle to the east incident angle of the plant, and from the time point a, the device is started to rotate to track the sun. The delay control time point B is the time when the device is in the horizontal attitude, at which time the plant is in the vertical attitude, the sun is shot from the east to the plant at the optimum angle of incidence, and at this time point the rotation is stopped, waiting for the sun to cross the top of the plant and change to the west side angle of incidence. The delay control time point C is the time when the sun has passed over the top of the plant to strike the plant from the west at the optimum angle of incidence, at which time the device starts tracking the sun for the second time. The delay time lengths X, Y, and Z need to be set in consideration of the speed of rotation of the hydraulic swing device 1, the flow valve can adjust the speed of rotation by using a proportional valve, the foregoing example of the present application also provides an optimized automatic control scheme, and details of this example are not further described here.
In the above example, we have calculated the delay control time point B at which the hydraulic swing device is in the horizontal attitude. Alternatively, in other examples of the present application, an attitude sensor may be used to sense that the hydraulic rotating device is in a horizontal attitude instead of the timing control of the delay control time point B. The attitude sensor is controllably connected to 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, so as to control the hydraulic swing device to stop rotating and wait until a time delay control time point C to restart the rotation of the hydraulic swing device. Attitude sensors for sensing the level of the hydraulic swing device may include, but are not limited to, angle sensors, position sensors, ball switches, etc.
