Description

Technical Field

[0001] This disclosure relates to the field of heavy object fixing technology, and in particular to a heavy object fixing device and a gravity energy storage system. Background Technology

[0002] Gravity energy storage is based on the height difference of a structure. It uses surplus electricity to lift a heavy object to a certain height, thus converting electrical energy into gravitational potential energy. This is also known as the energy storage process. During the fall of the heavy object, a transmission mechanism drives a generator to generate electricity, thus converting gravitational potential energy into electrical energy. This is also known as the energy release process.

[0003] After the heavy object is lifted to the top of the structure, it needs to be stationary for a period of time using a fixing device to store energy. Current fixing methods mostly include mechanical arm clamping, wire rope hoisting, gear and rack meshing, and lower support fixing. However, the heavy objects usually weigh tens or hundreds of tons, and these fixing methods are not very stable and are complicated to operate, making it difficult to meet the requirements of high reliability and high efficiency gravity energy storage. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, the purpose of this disclosure is to provide a heavy object fixing device and a gravity energy storage system.

[0006] To achieve the above objectives, the first aspect of this disclosure provides a heavy object fixing device, comprising: a fixing rod rotatably mounted on a structure; a fixing sleeve mounted on the heavy object, with the fixing sleeve and the fixing rod arranged opposite to each other along the lifting direction of the heavy object; a driving assembly mounted on the structure and pulsatorically connected to the fixing rod; and a control module, the output end of which is connected to the input end of the driving assembly. The control module is used to drive the fixing rod to rotate using the driving assembly when the heavy object rises to a first height, so that the fixing sleeve is threaded onto the fixing rod, thereby fixing the heavy object on the structure.

[0007] Optionally, the weight fixing device further includes a lubrication component, which is slidably disposed on the structure, and the lubrication end of the lubrication component is threaded onto the fixing rod; wherein, when the fixing rod rotates, the lubrication end of the lubrication component moves on the fixing rod and lubricates the fixing rod.

[0008] Optionally, the lubrication assembly includes: a support frame slidably disposed on the structure; a lubrication sleeve disposed on the support frame and threaded onto the fixed rod; and an oil supply channel disposed within the support frame and the lubrication sleeve, with the oil inlet end of the oil supply channel disposed on the support frame and the oil outlet end of the oil supply channel disposed on the lubrication sleeve.

[0009] Optionally, the weight fixing device further includes a guide sleeve, which is disposed at one end of the fixing sleeve near the fixing rod, and the diameter of the guide sleeve increases linearly along the direction from the fixing sleeve to the fixing rod.

[0010] Optionally, the fixing rod is provided with an external thread, and the fixing sleeve is provided with an internal thread; wherein, the control module is used to drive the fixing rod to rotate using the drive assembly when the weight rises to a first height, so that the external thread and the internal thread engage.

[0011] Optionally, the heavy object fixing device further includes: a first sensor, which is disposed on the structure and located at the first height, the output end of the first sensor being connected to the input end of the control module, and the first sensor being used to detect the heavy object; wherein, the control module is used to drive the fixing rod to rotate using the driving component when the first sensor detects the heavy object.

[0012] Optionally, the weight fixing device further includes: a second sensor, which is disposed on the structure and located at a second height. The output end of the second sensor is connected to the input end of the control module. The second sensor is used to detect the weight. The second height is greater than the first height. The control module is used to stop the rotation of the fixing rod by using the drive assembly when the second sensor detects the weight.

[0013] Optionally, the heavy object fixing device further includes: a slewing bearing, the outer ring of which is disposed on the top load-bearing beam of the structure, and the inner ring of which is sleeved on the fixed rod; and a first vibration damper, the first vibration damper including: a damping ring and a plurality of first springs, the damping ring being rotatably sleeved on the fixed rod, and the first springs being disposed between the damping ring and the load-bearing beam, the plurality of first springs being evenly distributed along the circumference of the fixed rod.

[0014] Optionally, the weight fixing device further includes a second vibration damper, which includes a vibration damping rod, a vibration damping block, and a plurality of second springs. The vibration damping block is movably disposed within the weight, and the plurality of second springs are disposed between the vibration damping block and the weight in multiple directions. One end of the vibration damping rod is connected to the vibration damping block, and the end of the vibration damping rod away from the vibration damping block passes through the weight and is connected to the fixing sleeve.

[0015] A second aspect of this disclosure provides a gravity energy storage system, comprising: a plurality of weight fixing devices as provided in the first aspect of this disclosure.

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] Because the fixing rod and fixing sleeve use a threaded connection to fix the heavy object, the heavy object is less likely to slip or become unstable after it is fixed. This makes the heavy object fixing device highly stable and safe, thus meeting the requirements for high reliability. At the same time, the fixing process of the fixing rod and fixing sleeve can be carried out synchronously with the lifting and lowering of the heavy object. The overall time is short and the response speed is fast, thus meeting the requirements for high efficiency.

[0031] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this disclosure proposes a heavy object fixing device, including: a fixing rod, a fixing sleeve, a driving assembly, and a control module (not shown in the figure). The fixing rod is rotatably mounted on the structure, the fixing sleeve is mounted on the heavy object, and the fixing sleeve and the fixing rod are arranged opposite to each other along the lifting direction of the heavy object. The driving assembly is mounted on the structure and is pulsatorically connected to the fixing rod. The output end of the control module is connected to the input end of the driving assembly. The control module is used to drive the fixing rod to rotate using the driving assembly when the heavy object rises to a first height, so that the fixing sleeve is threaded onto the fixing rod, thereby fixing the heavy object on the structure.

[0033] Understandably, since the fixed rod is rotatably mounted on the structure and the fixed sleeve is mounted on the heavy object, and the fixed sleeve and the fixed rod are positioned opposite each other along the lifting direction of the heavy object, the fixed rod can use its own rotation to connect or separate from the fixed sleeve during the lifting process. Thus, when the heavy object rises to the first height, the control module uses the drive component to drive the fixed rod to rotate, which allows the fixed sleeve to be threaded onto the fixed rod, thereby fixing the heavy object on the structure and thus meeting the requirement of fixing the heavy object.

[0034] The fixing rod and the fixing sleeve use a threaded connection to fix the heavy object, which makes it less likely for the heavy object to slip or become unstable after it is fixed. This gives the heavy object fixing device high stability and safety, thus meeting the requirements for high reliability. At the same time, the fixing process of the fixing rod and the fixing sleeve can be carried out synchronously with the lifting and lowering of the heavy object. The overall time is short and the response speed is fast, thus meeting the requirements for high efficiency.

[0035] Meanwhile, since the heavy object fixing device only involves the threaded engagement of the fixing rod and the fixing sleeve, the overall structure is simpler, thereby reducing the space occupied by the heavy object fixing device and making its use more flexible. It also makes the overall electrical control simpler, thereby reducing the failure rate of the heavy object fixing device and making its reliability higher.

[0036] It should be noted that a structure refers to an engineering entity or ancillary building facility constructed for a certain purpose. The structure does not provide human habitation functions. However, when a heavy object fixing device is applied to a gravity energy storage system, the structure is a tower-shaped building, which is used to accommodate heavy objects and provide lifting space for them.

[0037] A heavy object refers to an object with a certain weight. When a heavy object fixing device is applied to a gravity energy storage system, the heavy object can be used for energy storage and release, that is, storing electrical energy as potential energy and releasing potential energy as electrical energy. Specifically, when the heavy object is placed in a structure, an lifting mechanism can be used to convert electrical energy into potential energy to achieve overall lifting. During the descent of the heavy object, a transmission mechanism drives a generator to operate, thereby releasing potential energy into electrical energy.

[0038] The fixing rod is used in conjunction with the fixing sleeve to fix and release the heavy object on the structure. The specific type of fixing rod can be set according to actual needs and there is no restriction on it. For example, the fixing rod is a rod-shaped structure and the axis of the fixing rod is located in the lifting direction of the heavy object, that is, the vertical direction.

[0039] The fixing sleeve is used in conjunction with the fixing rod to fix and release the heavy object on the structure. The specific type of fixing sleeve can be set according to actual needs and there is no restriction. For example, the fixing sleeve is a sleeve structure, the inner surface of the fixing sleeve is adapted to the outer surface of the fixing rod, and the axis of the fixing sleeve is located in the lifting direction of the heavy object.

[0040] The drive assembly is used to drive the rotation of the fixed rod. The specific type of drive assembly can be set according to actual needs and is not limited thereto. For example, the drive assembly can be a rotary motor, which is fixedly mounted on the top load-bearing beam of the structure. The rotation speed of the rotary motor can be set according to the lifting speed of the load to ensure that the fixed rod and the fixed sleeve can be stably engaged during the lifting process.

[0041] When the load is lifted, the drive assembly drives the fixed rod to rotate in the forward direction so that the fixed sleeve is threaded onto the fixed rod. The drive assembly then drives the fixed rod to rotate in the reverse direction so that the fixed sleeve is disengaged from the fixed rod.

[0042] The control module is used to control the drive component according to the height of the load and external instructions, so as to drive the fixed rod to rotate forward and backward. The specific type of control module can be set according to actual needs and there is no restriction. For example, the control module can be a controller.

[0043] like Figure 1 As shown, in some embodiments, the heavy object fixing device further includes a lubrication component, which is slidably disposed on the structure, and the lubrication end of the lubrication component is threaded onto the fixing rod, wherein when the fixing rod rotates, the lubrication end of the lubrication component moves on the fixing rod and lubricates the fixing rod.

[0044] Understandably, since the lubrication assembly is slidably mounted on the structure and the lubrication end of the lubrication assembly is threaded onto the fixed rod, the fixed rod can use its own rotation to drive the lubrication end of the lubrication assembly to move during the lifting and lowering of the heavy object. This allows the lubrication end of the lubrication assembly to contact different positions on the fixed rod, thereby meeting the lubrication requirements and ensuring the stable connection and disengagement of the fixed rod and the fixed sleeve.

[0045] It should be noted that the lubrication component is used to lubricate the fixed rod, and the specific type of lubrication component can be set according to actual needs, without any restrictions.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the lubrication assembly includes: a support frame, a lubrication sleeve, and an oil supply channel (not shown in the figure). The support frame is slidably mounted on the structure, the lubrication sleeve is mounted on the support frame and threaded onto a fixed rod, the oil supply channel is located inside the support frame and the lubrication sleeve, and the oil inlet end of the oil supply channel is located on the support frame and the oil outlet end of the oil supply channel is located on the lubrication sleeve.

[0047] Understandably, since the support frame is slidably mounted on the structure and the lubricating sleeve is mounted on the support frame, with the lubricating sleeve threaded onto the fixed rod, the fixed rod can drive the lubricating sleeve to move by its own rotation during the lifting and lowering of the load. This allows the oil inlet end of the oil supply channel on the lubricating sleeve to contact different positions on the fixed rod, thereby using lubricating oil to meet the lubrication requirements and ensuring the stable connection and disconnection of the fixed rod and the fixed sleeve.

[0048] It should be noted that the support frame is used to support the lubrication sleeve and oil supply channel to ensure the stable movement of the sliding sleeve. The specific type of support frame can be set according to actual needs and there is no restriction. For example, the support frame is a frame structure that is close to "U". The two ends of the support frame are slidably set on the top load-bearing beam of the structure along the lifting direction of the load, and the two ends of the support frame are connected to the two sides of the lubrication sleeve. Thus, when the fixed rod rotates, the fixed rod can drive the lubrication sleeve to move along the axial direction of the fixed rod.

[0049] The lubrication sleeve is used for transmission with the fixed rod and to support the oil supply channel. The specific type of lubrication sleeve can be set according to actual needs and there is no limitation. For example, the lubrication sleeve is a sleeve structure, and the inner surface of the lubrication sleeve is adapted to the outer surface of the fixed rod.

[0050] The oil supply channel is used to guide lubricating oil so that it can enter the surface of the fixed rod from the lubrication sleeve, thereby ensuring a stable fit between the fixed rod and the fixed sleeve. The specific type of oil supply channel can be set according to actual needs and is not limited thereto. For example, part of the oil supply channel is set inside the support frame and another part is set inside the lubrication sleeve. At the same time, the oil inlet end of the oil supply channel passes through the support frame and is connected to the oil outlet end of the oil tank, while the oil outlet end of the oil supply channel passes through the lubrication sleeve and faces the fixed rod.

[0051] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the weight fixing device further includes a guide sleeve, which is disposed at the end of the fixed sleeve near the fixed rod, and the diameter of the guide sleeve increases linearly along the direction from the fixed sleeve to the fixed rod.

[0052] Understandably, since the guide sleeve is located at the end of the fixed sleeve near the fixed rod, and the diameter of the guide sleeve increases linearly along the direction from the fixed sleeve to the fixed rod, when the fixed rod and the fixed sleeve approach each other, the fixed rod can use the guide sleeve to stably align with the fixed sleeve, thereby avoiding misalignment between the fixed rod and the fixed sleeve, and thus ensuring a stable connection between the fixed rod and the fixed sleeve.

[0053] It should be noted that the guide sleeve is used to guide the fixed rod. That is, the bucket-shaped structure of the guide sleeve allows the end of the fixed rod closest to the fixed sleeve to first enter the guide sleeve and then enter the fixed sleeve. The specific type of guide sleeve can be set according to actual needs and there is no restriction on it. For example, the guide sleeve is a bucket-shaped sleeve structure, and its inner diameter at the end away from the fixed rod is the same as the inner diameter at the end of the fixed sleeve closest to the fixed rod.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the fixing rod is provided with an external thread and the fixing sleeve is provided with an internal thread (not shown in the figure). The control module is used to drive the fixing rod to rotate by the drive assembly when the weight rises to a first height, so that the external thread and the internal thread are engaged.

[0055] It is understandable that, since the fixing rod has an external thread and the fixing sleeve has an internal thread, the fixing rod can rotate under the drive of the drive component during the lifting and lowering of the heavy object. The external and internal threads are used to connect or separate the fixing rod from the fixing sleeve, thereby meeting the needs of fixing and releasing the heavy object.

[0056] It should be noted that the external thread is a threaded structure set on the outer surface of the fixed rod, while the internal thread is a threaded structure set on the inner surface of the fixed sleeve. The internal thread and the external thread cooperate to achieve the threaded connection between the fixed rod and the fixed sleeve.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the heavy object fixing device further includes: a first sensor, which is disposed on the structure and located at a first height, the output end of the first sensor is connected to the input end of the control module, and the first sensor is used to detect the heavy object; wherein, the control module is used to drive the fixing rod to rotate using a drive assembly when the first sensor detects the heavy object.

[0058] It is understandable that, since the first sensor is installed on the structure and is located at a first height, and the output of the first sensor is connected to the input of the control module, the first sensor can detect the heavy object and send the detected signal to the control module, so that the control module controls the drive component according to the signal sent by the first sensor, thereby using the drive component to drive the fixed rod to rotate, and thus fix the heavy object.

[0059] It should be noted that the first sensor is used to detect heavy objects. The specific type of the first sensor can be set according to actual needs and there is no restriction on it. For example, the first sensor can be a laser sensor. When the top of the heavy object reaches the first height, it will block the first sensor, thereby causing the first sensor to generate a signal.

[0060] The specific height value of the first height can be set according to actual needs, and there are no restrictions on it.

[0061] like Figure 1 and Figure 3 As shown, in some embodiments, the heavy object fixing device further includes: a second sensor, which is disposed on the structure and located at a second height. The output end of the second sensor is connected to the input end of the control module. The second sensor is used to detect the heavy object. The second height is greater than the first height. The control module is used to stop the rotation of the fixing rod by using a drive component when the second sensor detects the heavy object.

[0062] Understandably, since the second sensor is installed on the structure and located at the second height, and the output of the second sensor is connected to the input of the control module, the second sensor can detect the heavy object and send the detected signal to the control module. This allows the control module to control the drive component based on the signal sent by the second sensor, thereby stopping the rotation of the fixing rod and thus fixing the heavy object.

[0063] It should be noted that the second sensor is used to detect heavy objects. The specific type of the second sensor can be set according to actual needs and there are no restrictions on it. For example, the second sensor can be a laser sensor. When the top of the heavy object reaches the second height, it will block the second sensor, thereby causing the second sensor to generate a signal.

[0064] The specific height value of the second height can be set according to actual needs and is not limited thereto. The height difference between the first height and the second height is close to or equal to the length of the fixing rod in the fixing sleeve.

[0065] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the heavy object fixing device further includes: a slewing bearing and a first vibration damper. The outer ring of the slewing bearing is disposed on the top load-bearing beam of the structure, and the inner ring of the slewing bearing is sleeved on the fixed rod. The first vibration damper includes: a damping ring and a plurality of first springs. The damping ring is rotatably sleeved on the fixed rod, and the first springs are disposed between the damping ring and the load-bearing beam. The plurality of first springs are evenly distributed along the circumference of the fixed rod.

[0066] It is understandable that, since the outer ring of the slewing bearing is set on the top load-bearing beam of the structure, and the inner ring of the slewing bearing is fitted on the fixed rod, the fixed rod can be rotatably set on the top load-bearing beam of the structure using the slewing bearing, and at the same time, the slewing bearing can be used to achieve stable load bearing on the heavy objects.

[0067] Because the damping ring is rotatably sleeved on the fixed rod, and the first spring is set between the damping ring and the load-bearing beam, and multiple first springs are evenly distributed along the circumference of the fixed rod, not only can the vibration between the heavy object and the structure be buffered by the first damper, but also the fixed rod can be adjusted in position by the cooperation of multiple first springs and the damping ring, thereby ensuring the alignment of the fixed rod and the fixed sleeve. Thus, the stable fixation of the heavy object is guaranteed, thereby meeting the requirements for high reliability.

[0068] It should be noted that the slewing bearing is used to fix the rotation of the rod and to ensure that the rod can withstand a large weight. The specific type of slewing bearing can be set according to actual needs and there is no restriction on it. The slewing bearing includes an inner ring, an outer ring and multiple balls. The inner ring is located above the outer ring and the multiple balls are arranged between the inner ring and the outer ring.

[0069] The damping ring is used to connect the first spring and the fixed rod. The specific type of damping ring can be set according to actual needs and there is no restriction. For example, the damping ring is a ring structure and is sleeved on the fixed rod through a bearing.

[0070] The first spring is used for vibration damping. The specific type and number of the first spring can be set according to actual needs and are not limited thereto. Furthermore, for better vibration damping, the first spring can also be configured with a damper.

[0071] like Figure 1 As shown, in some embodiments, the weight fixing device further includes a second vibration damper, which includes a vibration damping rod, a vibration damping block, and a plurality of second springs. The vibration damping block is movably disposed inside the weight, and the plurality of second springs are disposed between the vibration damping block and the weight in multiple directions. One end of the vibration damping rod is connected to the vibration damping block, and the end of the vibration damping rod away from the vibration damping block passes through the weight and is connected to the fixing sleeve.

[0072] Understandably, since the damping block is movably installed inside the heavy object, and multiple second springs are respectively installed between the damping block and the heavy object in multiple directions, one end of the damping rod is connected to the damping block, and the end of the damping rod away from the damping block passes through the heavy object and is connected to the fixed sleeve. This not only allows the vibration between the fixed sleeve and the heavy object to be buffered by the second damper, but also allows the fixed sleeve to be adjusted in position by the cooperation of multiple second springs and the damping block, thereby ensuring the alignment of the fixed rod and the fixed sleeve. Thus, the stable fixation of the heavy object is ensured, thereby meeting the requirements for high reliability.

[0073] It should be noted that the damping rod is used to connect the damping block and the fixing sleeve. The specific type and number of damping rods can be set according to actual needs and there is no restriction. For example, the damping rod is a rod-shaped structure, and the weight is provided with an opening for the damping rod to pass through. The size of the opening is larger than the damping rod but smaller than the damping block.

[0074] Vibration damping blocks are used to connect the fixed sleeve and the weight, as well as to dampen vibrations between the fixed sleeve and the weight. The specific type and quantity of vibration damping blocks can be set according to actual needs and are not limited thereto. For example, the vibration damping block has a structure close to a cuboid. One side of the vibration damping block is connected to the vibration damping rod, and the other five sides of the vibration damping block are respectively provided with second springs. The weight is provided with a cavity to accommodate the vibration damping block. The cavity is connected to the opening on the weight, and the size of the cavity is larger than the size of the vibration damping block.

[0075] The second spring is used for vibration damping. The specific type and number of the second spring can be set according to actual needs and are not limited thereto. Furthermore, for better vibration damping, the second spring can also be configured with a damper.

[0076] This disclosure also proposes a gravity energy storage system, including: a plurality of weight fixing devices as described in the embodiments of this disclosure.

[0077] Understandably, since the fixed rod is rotatably mounted on the structure and the fixed sleeve is mounted on the heavy object, and the fixed sleeve and the fixed rod are positioned opposite each other along the lifting direction of the heavy object, the fixed rod can use its own rotation to connect or separate from the fixed sleeve during the lifting process. Thus, when the heavy object rises to the first height, the control module uses the drive component to drive the fixed rod to rotate, which enables the fixed sleeve to be threaded onto the fixed rod, thereby fixing the heavy object on the structure and meeting the requirements for fixing the heavy object in gravity energy storage.

[0078] The fixing rod and the fixing sleeve use a threaded connection to fix the heavy object, which makes it less likely for the heavy object to slip or become unstable after it is fixed. This gives the heavy object fixing device high stability and safety, thus meeting the requirements for high reliability. At the same time, the fixing process of the fixing rod and the fixing sleeve can be carried out synchronously with the lifting and lowering of the heavy object. The overall time is short and the response speed is fast, thus meeting the requirements for high efficiency.

[0079] It should be noted that gravity energy storage systems utilize multiple weight-fixing devices to distribute the weight, allowing for the installation of relatively large objects. The specific type of gravity energy storage system can be chosen based on actual needs and is not limited thereto.
