Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gravity energy storage, in particular to a continuous operation type circulating device and a gravity energy storage system. BACKGROUND

[0002] Gravity energy storage is a method of storing energy using gravitational potential energy. The basic principle is to store energy by lifting gravity power generation blocks to a high place, and when energy needs to be released, the gravity power generation blocks are lowered to drive the generator to generate electricity.

[0003] The existing gravity energy storage device has the following problems: first, the existing gravity energy storage system cannot realize continuous operation, and the front-end mechanical input device connected with the motor or generator is started and stopped at times. Each start and stop will have a great impact on the output power, so that the charging or discharging power of the gravity energy storage presents a "step, non-smooth" adjustment characteristic, which causes the gravity energy storage device to be unable to be directly connected to the grid. In addition, due to the large mass of the heavy blocks, usually several dozen tons, and the process of time sequence input and output of the heavy blocks, a certain power disturbance will be caused, which will cause power quality problems. Second, the power of the existing gravity energy storage device is limited. Most of the current gravity energy storage power generation channels have only one heavy block driving mechanical device and generator at a time. The output power of this channel is limited by the weight and descending speed of the single heavy block. Limited by the space, material and economy of the heavy block, the weight of the heavy block is limited to the order of tens of tons, which is difficult to improve; limited by the mechanical coupling device and the large weight bearing capacity, the running speed of the channel loaded with heavy blocks is limited to the order of m / s, usually around 1-2 m / s, which is difficult to improve. The current method of improving the power is to use multiple channels to cooperate to generate electricity, and to use shafts to couple the mechanical devices of multiple channels to drive a high-power generator to generate electricity, but this method has the following disadvantages: first, it increases the investment in equipment, which increases the unit power cost and reduces the economy; second, the complex shaft cooperation increases the mechanical wear, which reduces the overall conversion efficiency. Third, in most gravity energy storage schemes, the heavy block bearing device corresponds to the heavy block, and the flexible scheduling of the heavy block cannot be realized, the equipment utilization rate is low, and the circulating efficiency of the bearing device is low.

[0004] In summary, the current gravity energy storage device has the problems of being unable to continuously and stably generate and store electricity, low working efficiency of gravity energy storage, and low recycling rate of equipment.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application and not all the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

In addition, the terms "first", "second", "third" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0024] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0025] In the description of the embodiments of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "communication", "connection" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be mechanically connected, can be electrically connected; can be directly connected, can be indirectly connected through an intermediate medium, or can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] According to a first aspect of the present application, a continuous operation circulating device is provided, as shown in the figure, for a gravity energy storage system, which can be docked with a conveying device 9 of the gravity energy storage system, and connect a weight block body 10, so that the weight block body 10 completes the circulating transportation. The continuous operation circulating device comprises a main body frame 1, a bearing circulating part 2, a continuous triggering part 3 and a connecting platform 4. Figures 1 to 15 According to a first aspect of the present application, a continuous operation circulating device is provided, as shown in the figure, for a gravity energy storage system, which can be docked with a conveying device 9 of the gravity energy storage system, and connect a weight block body 10, so that the weight block body 10 completes the circulating transportation. The continuous operation circulating device comprises a main body frame 1, a bearing circulating part 2, a continuous triggering part 3 and a connecting platform 4.

[0027] In the following description, reference will be made to Figures 1 to 15 The detailed structure of the main frame 1, the carrying circulating part 2, the continuous triggering part 3 and the connecting platform 4 of the continuous operation circulating device will be described in detail.

[0028] As Figures 1 to 3 shown, in the embodiment, the main frame 1 can be composed of steel materials for accommodating the main body of the carrying circulating part 2, the continuous triggering part 3 and the connecting platform 4, and the splicing mode can be selected according to different positions and different needs, such as welding or threaded connection by using fastening bolts. The height of the main frame 1 can be selected according to the needs of the gravity energy storage system, for example, in the embodiment, the conveying device 9 includes four conveying lines located in the upper part and four conveying lines located in the lower part, so the height of the main frame 1 needs to meet the transportation of these conveying lines and the required height of the heavy block body 10 to realize the power generation or electricity storage of the gravity energy storage. Figure 1 Figure 1

[0029] ​​The carrying circulation section 2, the continuous triggering section 3, and the connecting platform 4 are all mounted on the main frame 1. The mounting method can be, for example, welding or threaded connection using fastening bolts, depending on the specific situation and location. Since these assembly and connection methods are common technologies, they will not be described in detail in this embodiment. The connecting platform 4 is used to receive the heavy object block body 10 from the conveying device 9 or to transfer the heavy object block body 10 to the conveying device 9. The continuous triggering section 3 can carry the heavy object block body 10 (the connecting platform 4 transports the heavy object block body 10 to the continuous triggering section 3, or removes the heavy object block body 10 from the continuous triggering section 3). The continuous triggering section 3 can dock with and trigger the carrying circulation section 2, allowing the carrying circulation section 2 to continuously and continuously receive the heavy object block body 10 from the continuous triggering section 3, or place the heavy object block body 10 on the continuous triggering section 3. The bearing circulation unit 2 can move the weight block body 10 from a high position to a low position to achieve power generation in gravity energy storage, or move the weight block body 10 from a low position to a high position to achieve electricity storage in gravity energy storage. It should also be noted that the core movement principle of the bearing circulation unit 2 is the cooperation form of the sprocket and chain. The cooperation form of the sprocket and chain can adopt the form of the prior art. Therefore, in the embodiment, except for the improved structure or the structure that cooperates with the continuous triggering unit 3 and other mechanisms, other aspects such as the combination relationship of the shaft and the sprocket, the setting position of the shaft and the generator (motor), or the need to set a set of sprockets and shafts at the upper and lower ends of the main frame 1 to achieve the chain circulation, will not be described in detail. Those skilled in the art can fully obtain the structure shown in the embodiment and the accompanying drawings by combining the key technical content described in the embodiment with the prior art. Similarly, the settings, fixed connections, cooperation connections or movement methods described below, unless otherwise specified, can all be welding, common snap-fit, threaded connection or sliding connection of slide rail and slide rail. Since these are all settings that those skilled in the art can choose to set, they will not be described in detail. Furthermore, since the weight of the gravity-stored energy block 10 is usually quite large, the entire device can be designed with a symmetrical structure to ensure stable movement (setting). Figure 1 If the front view is taken as the left view of the entire device, then the left view of the device is formed as a symmetrical structure, that is, there are two drive chains 201, and one continuous trigger part 3 is also symmetrically arranged on each side, and is respectively arranged on both sides of the bearing mechanism 202. If the symmetrical structure is not specifically emphasized in the following description, then it should be understood in accordance with the common symmetrical arrangement structure known to those skilled in the art and in conjunction with the accompanying drawings. These understandings are known to those skilled in the art and will not be repeated here.

[0030] Specifically, such as Figures 2 to 4As shown, the carrying cycle 2 includes a driving chain 201 and a carrying mechanism 202 for carrying the weight block body 10, and the driving chain 201 and the carrying mechanism 202 can be fixed by screw connection (for example Figure 5 As shown, the driving chain 201 only shows the part fixed with the carrying mechanism 202). In addition, in order to ensure the movement of the carrying mechanism 202, the driving chain 201 can be arranged in two parallel rows, forming a left-right symmetrical structure.

[0031] Further, the carrying mechanism 202 includes a fixed part 203 and a movable holding part 204, the fixed part 203 is driven by the driving chain 201, and its posture will change with the driving of the driving chain 201, so that the carrying mechanism 202 can pass through the two annular positions at the top and bottom of the carrying cycle 2 without being interfered. The movable holding part 204 directly carries the weight block body 10 and is rotatably arranged on the fixed part 203, so it is affected by its own gravity and the gravity of the weight block body 10. In the case that the posture of the fixed part 203 changes, the movable holding part 204 can always maintain a posture, so as to avoid the weight block body 10 on the movable holding part 204 from falling off. Here, please refer to the three states in Figures 11 to 13 for understanding.

[0032] It is emphasized here that no matter whether the carrying mechanism 202 receives the weight block body 10 or places the weight block body 10 on the continuous trigger 3, the carrying mechanism 202 always approaches the continuous trigger 3 from below, that is, in Figure 1 the driving chain 201 is always in a clockwise rotation state.

[0033] Further, the continuous trigger 3 is rotatably arranged on the main frame 1, and the continuous trigger 3 includes a contact rod, a projection of the contact rod in the vertical direction falls into the fixed part 203, and the weight block body 10 is placed on the contact rod. The contact rod is the end rod of the trigger rotating part 310 and the carrying rotating part 311 described below. In the case that the carrying cycle 2 is connected with the continuous trigger 3, the driving chain 201 drives the carrying mechanism 202 to move towards the continuous trigger 3, the fixed part 203 pushes the contact rod to rotate, so that the movable holding part 204 receives the weight block body 10 from the continuous trigger 3 or places the weight block body 10 on the continuous trigger 3. The continuous trigger 3 is pushed by the fixed part 203 to rotate once, so that the weight block body 10 on the contact rod falls into the carrying cycle 2.

[0034] The continuous operation circulating device can continuously and stably generate and store electricity by the cooperation of the main frame 1, the bearing circulating part 2, the continuous trigger part 3 and the docking platform 4, and the bearing circulating part 2 can continuously receive or place the heavy block body 10 from the continuous trigger part 3 without stopping, thereby solving the problem that the existing gravity energy storage device cannot continuously and stably generate and store electricity.

[0035] Preferably, as shown in the embodiment, the movable holding part 204 can include a movable receiving plate 205, a receiving clamping block 206 and a movable locking plate 207. Figures 4 to 7 The movable receiving plate 205 is rotatably arranged on the fixed part 203, and the movable receiving plate 205 can be rotatably arranged on the fixed part 203 through the cooperation of a bearing and a rotating shaft, so as to realize the posture holding. Figure 6 The end part of the rotating connection can be arranged at the top end of the fixed part 203 and the movable receiving plate 205. Figure 7 The receiving clamping block 206 is rotatably arranged on the end part of the movable receiving plate 205, and the end part can be the bottom end of the movable receiving plate 205. Figure 6 The receiving clamping block 206 is arranged in the rotating groove of the movable receiving plate 205 through a rotating shaft. Figure 7 The side part of the receiving clamping block 206 is provided with a torsional spring, the torsional spring is sleeved on the rotating shaft, the torsional spring has a certain limiting force, so that the receiving clamping block 206 is always in the horizontal receiving state shown in Figure 6 without the influence of external force, that is, the heavy block body 10 is placed on the receiving clamping block 206, if the receiving clamping block 206 is locked, the movable holding part 204 can be used to receive the heavy block body 10, if the receiving clamping block 206 is not locked, the heavy block body 10 is placed on the receiving clamping block 206, due to the heavy weight of the heavy block body 10, the receiving clamping block 206 is directly broken through the pulling force of the torsional spring, so that the heavy block body 10 cannot be placed on the movable holding part 204 or falls off from the movable holding part 204), in addition, one movable holding part 204 includes two receiving clamping blocks 206, one movable holding part 204 is arranged on the left and right sides of the fixed part 203, and the four receiving clamping blocks 206 of the two movable holding parts 204 are arranged opposite to each other, the gap between the two opposite receiving clamping blocks 206 is smaller than the size of the heavy block body 10, so as to clamp and receive the heavy block body 10.

[0036] The movable locking plate 207 is movably arranged on the movable receiving plate 205, two parallel arranged pin shafts are installed on the side of the movable receiving plate 205, the movable locking plate 207 is provided with a sliding groove, the pin shafts are arranged in the sliding groove, the size of the end of the pin shaft away from the movable receiving plate 205 is larger than the size of the sliding groove of the movable locking plate 207, so as to limit the position. The top surface of the movable locking plate 207 is connected with the side surface of the movable receiving plate 205 through the tension spring 208, the normal state of the tension spring 208 is shown in Figure 7 , Figure 6 , the tension spring 208 in Figure 7 is in the state after being stretched. The left end of the movable locking plate 207 is provided with a pulley, the left end provided with the pulley can contact and slide with the following end contact block 304, if the position of the following end contact block 304 does not change, the movable locking plate 207 will be pushed up, so that the movable locking plate 207 is in the state shown in Figure 6 , if the position of the following end contact block 304 changes, the movable locking plate 207 does not contact with the end contact block 304, the movable locking plate 207 is limited by the tension spring 208, and the receiving clamping block 206 is always locked.

[0037] In this way, the movable locking plate 207 can be switched between the locking state (as shown in Figure 7 ) and the unlocking state (as shown in Figure 6 ), the receiving clamping block 206 can be switched between the movable state (as shown in Figure 6 ) and the fixed state (as shown in Figure 7 ), when the movable locking plate 207 is in the locking state (at this time, the two pulleys at the bottom of the movable locking plate 207 are respectively located on the two receiving clamping blocks 206), the locking end (i.e. the end provided with the two pulleys) of the movable locking plate 207 abuts against the receiving clamping block 206, so that the receiving clamping block 206 keeps the fixed state and bears the weight block body 10; when the movable locking plate 207 is in the unlocking state (at this time, the two pulleys of the movable locking plate 207 are separated from the two receiving clamping blocks 206), the locking end of the movable locking plate 207 is separated from the receiving clamping block 206, so that the receiving clamping block 206 is in the movable state and can put down the weight block body 10.

[0038] Preferably, as shown in Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, in the embodiment, the continuous trigger part 3 can further comprise a linkage unlocking mechanism 301, which comprises a linkage fixing plate 303, an end contact block 304, a first linkage rod 305, a second linkage rod 306, a third linkage rod 307, and a linkage rotating block 308. The linkage fixing plate 303 is arranged on the main body frame 1, and the number of the linkage fixing plate 303 can be two, which respectively support the first linkage rod 305, the second linkage rod 306, and the third linkage rod 307, so that the three can move freely. The two ends of the first linkage rod 305 are respectively connected with the end contact block 304 and the first end of the second linkage rod 306, and the middle part of the first linkage rod 305 is rotatably arranged on the linkage fixing plate 303 through a bearing. The second end of the second linkage rod 306 is movably arranged on the first end of the third linkage rod 307, and the first end of the third linkage rod 307 is provided with a sliding groove. The second end of the second linkage rod 306 is slidably arranged in the sliding groove through a bearing. The second end of the third linkage rod 307 is rotatably connected with the linkage rotating block 308, and the two ends of the linkage rotating block 308 can be rotatably connected with the second end of the third linkage rod 307 and the fork type transplanting machine 408 of the docking platform 4 through pins. The middle part of the third linkage rod 307 is also provided with a sliding groove, and the top of the linkage fixing plate 303 connected with the third linkage rod 307 is provided with two bearings. The third linkage rod 307 is movably arranged on the top of the linkage fixing plate 303 through the cooperation of the bearings and the sliding grooves, and is limited by the two bearings, so that the third linkage rod 307 can only move left and right. In this way, when the fork type transplanting machine 408 of the docking platform 4 moves, the linkage rotating block 308 is driven to move, so that the third linkage rod 307 moves transversely, and then the second linkage rod 306 and the first linkage rod 305 rotate and deviate, thereby driving the end contact block 304 to deviate, so that the end contact block 304 switches between the positioning state (as shown in Figure 8 ) and the deviated state (as shown in Figure 9 ). When the end contact block 304 is in the positioning state, the end contact block 304 can abut against the linkage end (i.e., the left end of the Figure 6 with the pulley) of the movable locking plate 207, and the movable locking plate 207 is in the unlocking state (as shown in Figure 6 ). When the end contact block 304 is in the deviated state, the end contact block 304 is separated from the linkage end of the movable locking plate 207, and the movable locking plate 207 is in the locking state (as shown in Figure 7 ).

[0039] Preferably, as shown in Figure 4 , Figure 5 , and Figure 10As shown, in the embodiment, the continuous trigger part 3 comprises a non-powered rotating assembly 302, which comprises a non-powered rotating shaft 309, a trigger rotating disc part 310 and a bearing rotating disc part 311, both of which are arranged on the non-powered rotating shaft 309, and both of which comprise contact rods, the projection of the contact rods of the trigger rotating disc part 310 in the vertical direction falls into the fixed part 203, and the projection of the contact rods of the bearing rotating disc part 311 in the vertical direction falls into the movable holding part 204. The trigger rotating disc part 310 and the bearing rotating disc part 311 can both be formed in a cross-shaped structure, i.e. the trigger rotating disc part 310 and the bearing rotating disc part 311 can comprise four contact rods, which make the bearing mechanism 202 rotate the trigger rotating disc part 310 and the bearing rotating disc part 311 by ninety degrees when one contact rod is pushed. Since the height of the fixed part 203 in the vertical direction is higher than that of the movable holding part 204, the trigger rotating disc part 310 is the structure triggered by the fixed part 203, while the bearing rotating disc part 311 is used to support the weight block body 10 together. Both ends of the non-powered rotating shaft 309 are installed on the main body frame 1 through bearing seats, and the structure is a common rotating shaft installation structure, which will not be described here.

[0040] Preferably, as Figure 4 , Figure 5 and Figure 10As shown, in the embodiment, the non-powered rotating assembly 302 further comprises a bearing set, which can include a bearing ratchet wheel 312 and a bearing pawl 313, the bearing ratchet wheel 312 is arranged on the non-powered rotating shaft 309, the bearing pawl 313 is rotatably arranged on the main body frame 1, the bearing ratchet wheel 312 includes a plurality of teeth, and the bearing pawl 313 can be clamped on the adjacent teeth, so that the bearing ratchet wheel 312 can rotate in the same direction as the bearing rotating disc member 311 and lock the rotation in the opposite direction; the bearing ratchet wheel 312 cooperates with the bearing pawl 313 to form a ratchet and pawl structure, so that the direction of rotation of the non-powered rotating shaft 309 is limited, avoiding the non-powered rotating shaft 309 from being incorrectly rotated by other external forces. The non-powered rotating assembly 302 can further include an anti-falling set, which can include an anti-falling ratchet wheel 314 and an anti-falling pawl 315, the anti-falling ratchet wheel 314 is arranged on the non-powered rotating shaft 309, the anti-falling pawl 315 is rotatably arranged on the main body frame 1, the anti-falling ratchet wheel 314 includes a plurality of teeth, the number of teeth of the anti-falling ratchet wheel 314 is greater than the number of teeth of the bearing ratchet wheel 312, for example, the bearing ratchet wheel 312 can be a quarter ratchet wheel, and the anti-falling ratchet wheel 314 can be a twenty-fourth ratchet wheel, the bearing ratchet wheel 312 corresponds to the bearing rotating disc member 311 and rotates ninety degrees each time. The anti-falling pawl 315 can be clamped on the adjacent teeth, so that the anti-falling ratchet wheel 314 can rotate in the same direction as the bearing rotating disc member 311 and lock the rotation in the opposite direction. The anti-falling ratchet wheel 314 can rotate fifteen degrees each time. In this way, the rotation direction of the bearing ratchet wheel 312 and the anti-falling ratchet wheel 314 is set according to the movement of the bearing mechanism 202 (since it is a symmetrical structure, the rotation is left reverse right forward), and the arrangement of the bearing ratchet wheel 312 and the anti-falling ratchet wheel 314 ensures the uniqueness of the action direction, even if it is pushed by the gravity of the weight block body 10 placed on it, it will not be reversed. The anti-falling ratchet wheel 314 can ensure the safety of the operation, if the non-powered rotating shaft 309 does not stop after rotating ninety degrees and is reversely clamped, then only relying on the bearing ratchet wheel 312, the next time it will be clamped when rotating one hundred and eighty degrees, which does not meet the requirements of the process flow, and there is a safety hazard, and after the anti-falling ratchet wheel 314 is arranged, it can be reversely clamped at one hundred and five degrees. In addition, it also ensures that the rotation error of the shaft can be controlled in a smaller range and degree value, so as to be corrected by other correction devices.

[0041] Preferably, as Figure 4 , Figure 5 and Figure 10As shown in the embodiment, the contact rod of the trigger rotating disc part 310 is provided with a sliding wheel, the side wall of the fixed part 203 is further provided with a calibration member 316, the end of the calibration member 316 is provided with a calibration groove, the calibration member 316 can be formed as a C-shaped structure which is extended from the side wall of the fixed part 203 towards the trigger rotating disc part 310, and the calibration groove is an inner groove of the C-shaped structure, which can accommodate a sliding wheel. When the sliding wheel is arranged in the calibration groove, the correction is realized, so that the position of the current trigger rotating disc part 310 is correct, and the next connection of the weight block body 10 can be in the correct work station.

[0042] Preferably, as shown in the embodiment, Figure 3 , Figures 11 to 14 As shown in the embodiment, the carrying cycle part 2 further comprises a limiting track assembly 5, which comprises a vertical track group and a turning track group. The vertical track group is arranged on the main body frame 1 in the vertical direction, and the turning track group is arranged at both ends of the main body frame 1 in the vertical direction. The carrying mechanism 202 is limited to move in the vertical direction by the vertical track group, and the carrying mechanism 202 moves along the turning track group to realize the position switching of the carrying mechanism 202. Specifically, the vertical track group can comprise a first vertical track body 501 and a second vertical track body 502, and the turning track group can comprise a first turning track body 503 and a second turning track body 504, and a sliding gap is arranged between the first turning track body 503 and the second turning track body 504.

[0043] Preferably, as shown in the embodiment, Figure 3 , Figure 5 , Figure 6 , Figures 11 to 14As shown, in the embodiment, the movable holding part 204 further comprises a limiting wheel set 6, which is arranged on the movable holding part 204 through the fixing part 203, that is, the limiting wheel set 6 and the movable holding part 204 are arranged on two opposite outer walls of the fixing part 203. The limiting wheel set 6 can comprise a plurality of vertical track wheels 601 and a plurality of steering track wheels 602, which can be two vertical track wheels 601 and two steering track wheels 602 in the embodiment, and the two vertical track wheels 601 are arranged to face each other, and the two steering track wheels 602 are arranged to face each other. The two vertical track wheels 601 and the two steering track wheels 602 can jointly form a cross-shaped structure. However, it should be noted that the two vertical track wheels 601 and the two steering track wheels 602 are not on the same sliding surface, because in the embodiment, the width of the sliding contact surface of the vertical track set is greater than the width of the sliding contact surface of the steering track set, which can avoid the vertical track wheels 601 from contacting the steering track set when the limiting wheel set 6 is switched from the vertical track set to the steering track set, thereby avoiding interference, but when sliding on the vertical track set, the two vertical track wheels 601 and one steering track wheel 602 can simultaneously contact the vertical track set, realizing three-point contact and ensuring stable movement. That is, when the limiting wheel set 6 is located in the vertical track set, the plurality of vertical track wheels 601 and at least one steering track wheel 602 jointly contact the vertical track set, and when the limiting wheel set 6 is located in the steering track set, the plurality of steering track wheels 602 jointly contact the steering track set. The first steering track body 503 and the second steering track body 504 can be formed into a moon-shaped plate and a ring-shaped plate respectively, and are fixed on the auxiliary frame 505 by bolts, and the two cooperate to form two annular guide tracks, which are the sliding gap between the two and the upper annular edge of the moon-shaped plate respectively, and the two annular guide tracks can be used for sliding of the two steering track wheels 602 respectively. At the same time, the first steering track body 503 and the second steering track body 504 are not concentric, in order to ensure that the posture of the movable holding part 204 does not tilt when the bearing mechanism 202 is reversed at the top or bottom of the main frame 1, and the weight block body 10 located thereon does not fall. In addition, in order to ensure stable movement, the limiting track assembly 5 is also formed into a left-right symmetrical structure; in order to ensure circulation, the top and bottom of the main frame 1 are provided with two limiting track assemblies 5 arranged left-right symmetrically.

[0044] Preferably, as Figure 3 and Figure 15As shown, in the embodiment, the docking platform 4 can include a height adjustment assembly, which includes a guide plate 401, a guide column 402, a docking frame 403, a cam bearing 404, a screw block mechanism 405, a driving motor 406, and a connecting table 407. The docking frame 403 is arranged on the main body frame 1, the screw block mechanism 405 is arranged on the docking frame 403, the two ends of the guide column 402 are connected to the docking frame 403 and the connecting table 407 respectively, the guide plate 401 is arranged between the docking frame 403 and the connecting table 407 and connected to the connecting table 407, the guide plate 401 is provided with an inclined sliding groove, the cam bearing 404 is arranged in the inclined sliding groove, and the screw block mechanism 405 drives the cam bearing 404 to change the position so as to drive the guide plate 401 to change the position and drive the guide column 402 to ascend and descend. The driving motor 406 is connected to the screw rod of the screw block mechanism 405 through a shaft coupling, the screw rod is connected to a nut, the rotation of the screw rod drives the nut to move left and right to change the position, the cam bearing 404 is arranged at the two ends of the nut and limited in the inclined sliding groove of the guide plate 401. The number of the guide columns 402 is multiple, and the multiple guide columns 402 are arranged at the four corners of the connecting table 407, so that the connecting table 407 can be driven to ascend and descend by the driving motor 406. The connecting table 407 is provided with a fork-type transplanting machine 408 (only part of the structure is shown in the figure for example), which can be a device in the prior art and can realize the extension of the forks for docking the heavy block body 10, and the above-mentioned linkage rotating block 308 is connected to the side wall of the fork-type transplanting machine 408, and drives the linkage rotating block 308 when the forks of the fork-type transplanting machine 408 extend.

[0045] It should be further pointed out that the remaining structures not described in the embodiment, such as frames, bearing seats or shaft couplings, are arranged for the purpose of assisting installation, and these structures do not limit the shape, as long as the connection relationship and connection strength can be met, and the person skilled in the art can select the appropriate shape and assembly method according to the use scene.

[0046] In addition, in order to facilitate the description of the overall movement process, the conveying device 9 in the gravity energy storage system is also described here. However, the conveying device 9 can adopt the structure in the prior art, and therefore, only an exemplary description is made here, and the conveying device 9 is not limited to the description in the embodiment, and other structures can also be adopted. For example, Figure 1As shown, a conveying device 9 can be installed at the upper and lower ends of the gravity energy storage system. These two conveying devices 9 have identical structures, and all structures are installed within a steel frame (not shown). In an embodiment, one conveying device 9 can include four conveyor lines, with one conveyor line corresponding to another. That is, the heavy block body 10 conveyed by the top conveyor 9 on the top conveyor line is transported to the bottom conveyor 9 on the top conveyor line (or vice versa, the heavy block body 10 is used for energy storage from bottom to top and for power generation from top to bottom). Each conveyor line can consist of a conveyor belt, conveyor chain, conveyor plate, or conveyor roller assembly, and is driven by a motor, thereby enabling the heavy block body 10 located at the top to move along the top conveyor line. Figure 1 The heavy block body 10 at the middle left end is transported to Figure 1 At the right end of the conveyor belt, the forklift transplanter 408 on the connecting platform 4 then transfers the heavy block body 10 to the continuous triggering unit 3. Multiple heavy block bodies 10 can exist on one conveyor belt at the same time. Each conveyor line is equipped with a continuous triggering unit 3 and a connecting platform 4.

[0047] The key operational processes of this continuous operation circulation device consist of three steps: the picking process, the storage process, and the transportation process on the connecting platform 4.

[0048] Retrieval Process: During retrieval, the forklift transplanter 408 extends towards the carrying mechanism 202 but does not immediately retract. Instead, it drives the linkage rotating block 308, causing the end contact block 304 to shift. At this time, the weight block body 10 is supported by the contact rods of the trigger turntable 310 and the carrying turntable 311 (the contact rod supporting the weight block body 10 is flush with the ground) (support is achieved through ratchet and pawl). Then, the carrying mechanism 202 rises from below. At the instant the receiving block 206 contacts the weight block body 10, the calibration component 316 on the side wall of the fixing part 203 simultaneously contacts the sliding wheel at the end of the trigger turntable 310. At this time, the movable locking plate 207 is in the position as... Figure 7 As shown, the receiving block 206 is locked. Therefore, as the carrying mechanism 202 continues to climb, the weight block body 10 is lifted by the receiving block 206 and moves away from the trigger turntable 310 and the carrying turntable 311. From the top view, the trigger turntable 310 and the carrying turntable 311 are offset from the four receiving blocks 206 (two on each side) to avoid interference. As the carrying mechanism 202 climbs further, the fixing part 203 pushes the contact rod of the trigger turntable 310, causing the unpowered rotating shaft 309 to rotate ninety degrees. The picking process ends when the sliding wheel of the trigger turntable 310 slides out of the groove of the calibration component 316.

[0049] The storage process: when the carrying mechanism 202 carries the weight block body 10 from below the continuous trigger part 3, the storage process starts once the calibration member 316 contacts the sliding of the trigger turntable part 310. Similarly, the fixed part 203 pushes the contact rod of the trigger turntable part 310 to rotate 90 degrees, and in the process, the next contact rod of the pushed trigger turntable part 310 contacts the bottom surface of the weight block body 10 at a certain time and generates a lifting force on the weight block body 10, and just after rotating 90 degrees, the next contact rod is in a horizontal state and supports the weight block body 10. At the same time, because the fork transplanting machine 408 is in an extended state, that is, the linkage rotating block 308 is not pushed, and the end contact block 304 is not offset, the movable receiving plate 205 is pushed away by the end contact block 304 (here, the contact surface of the end contact block 304 is inclined, so that the pushing away process of the movable receiving plate 205 is smooth and stable), so that the movable retaining part 204 is in the state shown in Figure 6 , at this time, the four receiving clamping blocks 206 cannot bear the gravity of the weight block body 10, and at this time, the carrying mechanism 202 is still in a state of continuously climbing, so the weight block body 10 makes the four receiving clamping blocks 206 overcome the torque of the torsion spring, and falls onto the trigger turntable part 310 and the carrying turntable part 311, so that the carrying mechanism 202 successfully puts down the weight block body 10 and leaves. After the weight block body 10 is supported by the trigger turntable part 310 and the carrying turntable part 311, it no longer moves with the carrying mechanism 202, and when the receiving clamping block 206 is no longer in contact with the weight block body 10, the storage process ends.

[0050] The carrying process of the docking platform 4: when carrying from left to right in Figure 1 , the fork transplanting machine 408 extends the forks to the left side to below the weight block body 10, the driving motor 406 is actuated (for example, forward rotation), so that the fork transplanting machine 408 on the connecting table 407 is lifted upward to support the weight block body 10; then the fork transplanting machine 408 moves the forks to the right side and moves the weight block body 10 above the trigger turntable part 310 and the carrying turntable part 311, then the driving motor 406 is reversed, the fork transplanting machine 408 and the weight block body 10 supported thereby are lowered together, and the weight block body 10 is placed on the contact rods of the trigger turntable part 310 and the carrying turntable part 311, until the forks are separated from the weight block body 10.

[0051] The entire operation process (based on the above-mentioned taking process, storage process, and carrying process of the docking platform 4) required for the gravity energy storage of the continuous operation type circulating device includes: When the entire machine device is in a power generation state, the weight block body 10 is in the state shown in Figure 1The top conveying device 9 stores the heavy block bodies 10, and then the heavy block bodies 10 on the conveying line of each layer are conveyed to the left side of the corresponding docking platform 4 through the top conveying device 9, and then the docking platform 4 carries the heavy block bodies 10 into the continuous trigger part 3. Then the carrying mechanism 202 climbs from below, enters the "goods taking process", takes away the heavy block bodies 10 after completing the process, continues to climb, completes the reversing (moves from the left side to the right side) through the reversing track group, and then descends, and then returns to the left side through the bottom reversing track group, and reaches the corresponding bottom continuous trigger part 3, enters the "goods storage process", and then the corresponding docking platform 4 carries the heavy block bodies 10 to the conveying line of the bottom conveying device 9, and then the conveying line transports one position of the heavy block bodies 10 to the left side, and then receives one heavy block body 10 to transport one position to the left side, until the whole layer of heavy block bodies 10 is stacked.

[0052] When the whole machine device is in the energy storage state, the heavy block bodies 10 on the right side of the carrying cycle part 2 are used to store energy, and the heavy block bodies 10 on the left side of the carrying cycle part 2 are used to release energy. Figure 1 The bottom conveying device 9 stores the heavy block bodies 10, and similarly, the bottom conveying device 9 transports one heavy block body 10 to the left side of the corresponding docking platform 4 each time, and then the docking platform 4 carries the heavy block bodies 10 into the continuous trigger part 3 of each layer. Then the carrying mechanism 202 climbs from below, enters the "goods taking process", and continues to climb to the position of the conveying line of the corresponding top conveying device 9, enters the "goods storage process", and then the docking platform 4 carries the heavy block bodies 10 to the conveying line, and then transports one position to the left side in sequence, until the layer is stacked.

[0053] In addition, it also needs to be explained that in the process of generating electricity, the power of the whole carrying cycle part 2 is provided by the heavy block bodies 10 on the right side (top) and the left side (bottom) of the carrying cycle part 2. Figure 1 The total gravity of the heavy block bodies 10 on the right side (top) is greater than that on the left side, so that the whole carrying cycle part 2 can keep circulating in one direction.

[0054] The continuous operation type circulating device can make the carrying cycle part continuously receive or place the heavy block bodies from the continuous trigger part without stopping, thereby solving the problem that the existing gravity energy storage device cannot continuously and stably generate electricity and store electricity. Since the continuous operation type circulating device can simultaneously connect to the conveying devices of multiple conveying lines, the working efficiency of the gravity energy storage can be improved. Since the carrying cycle part can simultaneously accommodate multiple carrying mechanisms, the recycling rate of the device can be improved.

[0055] In addition, as Figure 1As shown, according to the second aspect of the present application, a gravity energy storage system is provided, which comprises the continuous operation circulating device and the conveying device 9 as described above.

[0056] Finally, it should be noted that the above-described embodiments are merely specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit the same. The protection scope of the present application is not limited thereto.
