Description

Technical Field

[0001] The invention belongs to the technical field of gravity conveying, and in particular relates to a gravity conveying device. Background Art

[0002] In mountainous areas or areas with many steep slopes, traditional transportation methods often face problems of low efficiency and high cost. In view of this, by utilizing gravitational potential energy and taking advantage of the height difference of the terrain, the goods can automatically slide down or rise under the action of gravity, without or with only a small amount of external power support, thereby achieving a significant reduction in transportation costs. The application of gravitational potential energy in the field of energy storage also shows broad prospects, and pumped storage power generation technology is an outstanding representative of this. During periods of low electricity demand, excess electricity is used to drive water pumps to pump water from low places to high reservoirs, thereby converting it into gravitational potential energy for storage; and when electricity demand surges, such as during the daytime of weekdays or during peak electricity consumption in hot summer, the water in the reservoir is released to generate electricity through turbines to meet the power demand of the power grid.

[0003] However, the current application mode of pumped hydroelectric storage technology has certain limitations. Usually, it can only pump water for energy storage during low electricity consumption, and focus on energy release and power generation during peak electricity consumption. When electricity consumption is extremely peak or when a sudden failure of the power grid requires emergency peak regulation, if the reservoir water level has dropped to a low level, the system will no longer be able to provide energy storage support, which limits its ability to respond to emergencies and affects the convenience and efficiency of use. Summary of the invention

[0004] The present invention provides a gravity conveying device for solving the technical problem that the current gravity energy storage cannot provide energy storage support when the power consumption is at an extreme peak or when a sudden power grid failure occurs.

[0006] Optionally, the water bucket includes a bucket body, a drainage groove, a sealing block and a driving block, wherein the bucket body is used to hold water; the drainage groove is installed on one side of the bucket body, the drainage groove is connected to the bucket body, and one side of the drainage groove is provided with a water outlet for drainage; the sealing block is slidably installed in the drainage groove; the driving block is installed outside the drainage groove, and the driving block is used to drive the sealing block to move to open and close the water outlet.

[0007] Optionally, the water bucket further includes a fixing plate, which is mounted on one side of the bucket body, and a placement opening for placing a counterweight is formed between the fixing plate and the bucket body.

[0008] Optionally, the width of the placement opening gradually increases from one end of the bucket body to the other end, and the counterweight block is adapted to the placement opening.

[0009] Optionally, it further comprises a pulley, which is arranged between the weight and the water bucket, and the traction rope is wound around the pulley.

[0010] Optionally, it also includes two electromagnets, which are arranged at the first position and the second position. The water bucket moves between the first position and the second position, and the water bucket moves under the electromagnet. The electromagnet attracts the counterweight block to move out of the placement port or places the counterweight block in the placement port.

[0011] Optionally, it also includes a guide rail, which is arranged between the pulley and the first position, and the water bucket is slidably installed on the guide rail.

[0012] Optionally, it also includes a guide wheel, which is rotatably mounted on the water bucket and located in the guide rail.

[0013] Optionally, a buffer is also included, and the buffer is installed at both ends of the guide rail.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] A gravity conveying device provided by the present invention includes a water bucket, a traction rope, a weight and a counterweight block. The water bucket has a water storage space for holding water. The water bucket moves back and forth between a first position and a second position to transport water from the first position to the second position. One end of the traction rope is connected to the water bucket, and the traction rope is used to drive the water bucket to move. The weight is installed at the other end of the traction rope to drive the water bucket to move from the first position to the second position through the traction rope. The counterweight block is detachably installed on one side of the water bucket, and the weight of the weight is less than the total weight of the water bucket and the counterweight block, so that the water bucket returns from the second position to the first position, and the weight of the weight is greater than the total weight of the water bucket and the objects in the water bucket.

[0016] Through the above structure, when a gravity conveying device provided by the present invention is used, a proper amount of water is filled into the water bucket, and then the weight hammer exerts force on one end of the traction rope through gravity, driving the water bucket at the other end of the traction rope to lift, so that the water bucket moves from the first position to the second position. When the water bucket moves to the second position, the water bucket stops moving. After the water bucket discharges the water, a counterweight block is installed on one side of the water bucket. The counterweight block exerts force on one end of the traction rope through gravity, so that the water bucket returns from the second position to the first position, and drives the weight hammer at the other end of the traction rope to reset, so as to facilitate the next lifting of the water bucket. Therefore, the gravity conveying device lifts water through the weight hammer and returns the water bucket by using the counterweight block, and does not need to rely on electricity or other means of energy supply, so that the gravity conveying device can be used even during peak power consumption or sudden power grid failure.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0030] The present invention provides a gravity conveying device to solve the technical problem that gravity energy storage cannot provide energy storage support when the power consumption is at an extreme peak or when the power grid fails. The gravity conveying device includes a bucket 1, a traction rope 2, a weight 3 and a counterweight 4, wherein:

[0031] The water bucket 1 is used to hold water, such as Figure 1-4 As shown, the bucket 1 has a water storage space 111. When transporting water, water is injected into and stored in the water storage space 111. The bucket 1 moves back and forth between the first position and the second position to transport water from the first position to the second position. In this embodiment, the height of the first position is less than that of the second position to meet the need to lift water. Figure 1-3 As shown, area A is the second position and area B is the first position.

[0032] One end of the traction rope 2 is connected to the water bucket 1, and force is applied to the other end of the traction rope 2 to drive the water bucket 1 to move through the traction rope 2.

[0033] like Figure 1-4 As shown, the weight 3 is installed on the end of the traction rope 2 away from the water bucket 1. The weight 3 is used to provide a driving force to drive the water bucket 1 to rise through the traction rope 2, so that the water bucket 1 moves from the first position to the second position. The water bucket 1 can also transport other items. It is worth noting that the total weight of the water bucket 1 and the objects in the water bucket 1 should be less than the weight 3.

[0034] like Figure 1-4 As shown, the counterweight 4 is detachably mounted on one side of the water bucket 1, and the counterweight 4 is used to drive the weight 3 and the water bucket 1 to return from the second position to the first position, so that the water bucket 1 is refilled with water, and the weight 3 can drive the water bucket 1 to move again. The weight of the weight 3 is less than the total weight of the water bucket 1 and the counterweight 4, so that the counterweight 4 can drive the weight 3 to rise and reset by gravity; items that need to be transported from a high place to a low place can also be placed in the water bucket 1, so that not only can the water bucket 1 return to the first position, but also the items can be transported. It is worth noting that when transporting items downward, the total weight of the items and the water bucket 1 needs to be greater than the weight of the weight; the weight of the weight 3 is greater than the total weight of the water bucket 1 and the objects in the water bucket 1, so that the weight 3 can drive the water bucket 1 to rise, and the water bucket can also be placed; in order to make the weight 3 And the water bucket 1 is reset. Every time the water bucket 1 rises and moves to the specified position, the counterweight 4 needs to be installed on the water bucket 1. When the water bucket 1 is lowered and reset, the counterweight 4 needs to be removed to facilitate filling water into the water bucket 1, and the water bucket 1 is driven to move again by the heavy hammer 3. The counterweight 4 can be transported to the second position by other means. For example, during the low electricity usage period, the counterweight 4 can be driven by electricity to move to the second position, and electricity can also be used to transport water from the first position to the second position during the low electricity usage period. During the peak electricity usage period, it is not suitable to use electricity to transport water from the first position to the second position. At this time, the heavy hammer 3 can be used to drive the water bucket 1 to move, so as to transport water from the first position to the second position, and the counterweight 4 can be used to return the water bucket 1 from the second position to the first position.

[0035] Through the above structure, when a gravity conveying device provided by the present invention is used, a proper amount of water is filled into the water bucket 1, and then the weight 3 applies force to one end of the traction rope 2 by gravity, driving the water bucket 1 at the other end of the traction rope 2 to be lifted, so that the water bucket 1 moves from the first position to the second position. When the water bucket 1 moves to the second position, the water bucket 1 stops moving. After the water bucket 1 discharges the water, the counterweight 4 is installed on one side of the water bucket 1. The counterweight 4 applies force to one end of the traction rope 2 by gravity, so that the water bucket 1 returns from the second position to the first position, and drives the weight 3 at the other end of the traction rope 2 to reset, so as to facilitate the next lifting of the water bucket 1. Therefore, the gravity conveying device lifts water through the weight 3, and returns the water bucket 1 by using the counterweight 4, so that the gravity conveying device can be used even during peak power consumption or sudden power grid failure.

[0036] An optional implementation of this embodiment is as follows: Figure 1-4 As shown, the bucket 1 includes a bucket body 11, a drainage groove 12, a sealing block 13 and a driving block 14. The bucket body 11 is used to hold water, and a water storage space 111 is provided in the bucket body 11; the drainage groove 12 is installed on one side of the bucket body 11, and the drainage groove 12 is connected to the water storage space 111 of the bucket body 11. When drainage is required, the water in the bucket body 11 can enter the drainage groove 12. A water outlet 121 is provided on one side of the drainage groove 12, and the water outlet 121 is used to discharge the water from the drainage groove 12. The sealing block 13 is slidably installed in the drainage groove 12, and the sealing block 13 slides to open and close the water outlet 121. Specifically, when the sealing block 13 slides to seal the water outlet 121, the bucket 11 is filled with water. When the sealing block 13 slides to the outside of the water outlet 121, the water outlet 121 is connected to the bucket 11, and the water in the bucket 11 is discharged to the outside of the bucket 11 through the water outlet 121; Optionally, the cross-section of the sealing block 13 in this embodiment is triangular, and the sealing block 1 When sealing the water outlet 121, one side of the sealing block 13 abuts against the water outlet 121, and the other side abuts against the side of the water bucket 1 close to the drain groove 12, so as to better seal the water outlet 121; the driving block 14 is installed outside the drain groove 12, and the driving block 14 is used to drive the sealing port to move, thereby driving the sealing port to open and close the water outlet 121; optionally, the driving block 14 can use an electromagnet, and the sealing block 13 can be a permanent magnet. When the driving block 14 is energized, the driving block 14 generates the same magnetic field as the sealing block 13, and the driving block 14 repels the sealing block 13, and the sealing block 13 moves in a direction close to the bucket body 11, so that the sealing block 13 abuts against the bucket body 11, and the sealing block 13 is sealed at the water outlet 121; when it is necessary to drain water, the current of the power supply is reversed, the driving block 14 generates a magnetic field opposite to that of the sealing block 13, and the start block attracts the sealing block 13 to move in a direction away from the bucket body 11, so that the sealing port is opened, and the water in the bucket body 11 is discharged through the drain outlet.

[0037] An optional implementation of this embodiment is as follows: Figure 4As shown, the bucket 1 further includes a fixing plate 15 , which is mounted on one side of the bucket body 11 , and a placement opening 151 is formed between the fixing plate 15 and the bucket body 11 , and the placement opening 151 is used to place the counterweight 4 .

[0038] An optional implementation of this embodiment is as follows: the width of the placement opening 151 gradually increases from one end close to the bottom of the bucket body 11 to the other end, and the counterweight block 4 is adapted to the placement opening 151, so that the user can slide the counterweight block 4 from the larger end, and then as the counterweight block 4 goes deeper, the width of the placement opening 151 gradually increases.

[0039] Specifically, when the counterweight block 4 is placed in the placement port 151, the width of the end of the counterweight block 4 close to the bottom of the bucket body 11 is smaller than the end of the counterweight block 4 away from the bottom of the bucket body 11. In this way, the counterweight block 4 can slide into or out of the placement port 151 smoothly when it is placed in the placement port 151 or when it is taken out from the placement port 151.

[0040] An optional implementation of this embodiment is as follows: Figure 1-3 As shown, the pulley 9 is arranged between the weight 3 and the water bucket 1, and the traction rope 2 is wound on the pulley 9. The pulley 9 serves as a guide and support component for the traction rope 2, which reduces the friction, thereby reducing energy loss and improving the transmission efficiency. More preferably, in order to ensure that the traction rope 2 can better fit the pulley 9 and maintain stable transmission, a groove can be provided on the circumferential surface of the pulley 9. The groove can not only provide a guide for the traction rope 2 to prevent it from deflecting or jumping during the transmission process, but also can increase the contact area and friction, so that the traction rope 2 is more firmly located on the pulley 9, thereby enhancing the stability and reliability of the transmission.

[0041] An optional implementation of this embodiment is as follows: Figure 1-3 As shown, the gravity conveying device also includes two electromagnets 5, which are arranged at a first position and a second position. The water bucket 1 moves between the first position and the second position. Before the water bucket 1 moves to the second position, the electromagnet 5 attracts the counterweight 4. When it is necessary to return the water bucket 1 from the second position to the first position, the electromagnet 5 is powered off, so that the counterweight 4 is placed in the placement port 151 under the action of gravity. After the counterweight 4 drives the water bucket 1 to move to the first position, the electromagnet 5 at the first position is powered on to attract the counterweight 4, so that the counterweight 4 moves out of the placement port 151.

[0042] An optional implementation of this embodiment is as follows: Figure 1-3As shown, the gravity conveying device also includes a guide rail 6, which is arranged between the pulley 9 and the first position, and the water bucket 1 is slidably installed on the guide rail 6. The guide rail 6 can not only guide the water bucket 1 so that the water bucket 1 can slide smoothly along the extension direction of the guide rail 6 to ensure that the water bucket 1 does not deviate from the track during the movement, but also provide support for the water bucket 1, effectively dispersing the weight of the water bucket 1 and the water it carries, reducing the tension on the traction rope 2, thereby extending the service life of the connecting rope. Since the guide rail 6 provides a stable support surface for the water bucket 1, the shaking of the water bucket 1 during the movement is reduced, and the water bucket 1 can slide more smoothly.

[0043] An optional implementation of this embodiment is as follows: Figure 1-3 As shown, the gravity conveying device also includes a guide wheel 7, which is rotatably mounted on the water bucket 1 and located in the guide rail 6. When the water bucket 1 slides along the guide rail 6, the guide wheel 7 reduces the friction between the water bucket 1 and the guide rail 6, so that the water bucket 1 moves more smoothly.

[0044] An optional implementation of this embodiment is as follows: Figure 1-3 As shown, the gravity conveying device also includes a buffer 8, which is installed at both ends of the guide rail 6. The buffer 8 is an element with energy absorption and buffering characteristics. When the water bucket 1 moves to the first position or the second position, the water bucket 1 first abuts against the buffer 8, and the buffer 8 buffers the water bucket 1. Through its internal energy absorption structure or material, the impact energy of the water bucket 1 is absorbed, thereby reducing the impact force of the water bucket 1, avoiding damage caused by direct impact, and extending the service life of the water bucket 1.

[0045] To sum up, when a gravity conveying device provided by the present invention is used, a proper amount of water is filled into the water bucket 1, and then the weight 3 applies force to one end of the traction rope 2 through gravity, driving the water bucket 1 at the other end of the traction rope 2 to be lifted, so that the water bucket 1 moves from the first position to the second position, and the pulley 9 guides and supports the traction rope 2, thereby reducing the friction force. The guide wheel 7 rotates in the guide rail 6 and moves along the guide rail 6. The guide rail 6 can not only guide the water bucket 1 so that the water bucket 1 can slide smoothly along the extension direction of the guide rail 6 to ensure that the water bucket 1 does not deviate from the track during the movement, but also provide support for the water bucket 1, effectively dispersing the weight of the water bucket 1 and the water body it carries, reducing the tension on the traction rope 2, thereby extending the service life of the connecting rope, and reducing the shaking of the water bucket 1 during the movement. When the water bucket 1 moves to the second position, the water bucket 1 stops moving, and the water bucket 1 first abuts against the buffer member 8. The buffer member 8 buffers the bucket 1 and absorbs the impact energy of the bucket 1, thereby reducing the impact force of the bucket 1 and avoiding damage caused by direct impact. The driving block 14 drives the sealing block 13 to move away from the bucket body 11, so that the sealing port is opened and the water in the bucket body 11 is discharged through the drain port. After the bucket 1 discharges the water, the driving block 14 and the sealing block 13 move toward the bucket body 11, so that the sealing block 13 abuts against the bucket body 11, and the sealing block 13 is sealed at the water outlet 121. The electromagnet 5 at the second position is powered off, so that the counterweight block 4 is placed in the placement port 151 under the action of gravity. The counterweight block 4 applies force to one end of the traction rope 2 through gravity, so that the bucket 1 returns from the second position to the first position, and drives the weight 3 at the other end of the traction rope 2 to reset, so as to facilitate the next lifting of the bucket 1. The electromagnet 5 at the first position attracts the counterweight block 4, so that the counterweight block 4 moves out of the placement port 151. Therefore, the gravity conveying device lifts water through the weight 3 and returns the water bucket 1 by using the counterweight block 4, without relying on electricity or other power supply methods, so that the gravity conveying device can be used even during peak power consumption or sudden power grid failure.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
