Description

Technical Field

[0001] The present invention relates to the technical field of electric energy storage and transportation management, and in particular to a track-type gravity energy storage transportation control system compatible with solid and liquid energy storage media. Background Art

[0002] In the traditional gravity energy storage rail transportation system, a high-level energy storage stack is set at a high position, and a low-level energy storage stack is set at a low position. The train is parked in the parking lot. Under the control of the controller, when the train is in power generation mode, the train enters the high-level energy storage stack receiving rail, and the gravity block of the high-level energy storage stack is clamped to the train car by a clamp. A train has at least a dozen cars, and each gravity block is placed in a car. After loading the gravity block, it enters the track and is transported to the downhill power generation rail to convert the gravitational potential energy into mechanical energy and then into electrical energy for electrical energy storage. After the train leaves the downhill power generation rail, it enters the low-level energy storage stack via the lower track. After unloading, it goes to the upward track for the next power generation transportation.

[0003] However, in actual applications, because this type of large energy storage system is mostly set up in mining areas and solid waste bulk material areas, most of them are open-air, during the rainy season, a large amount of rainwater can be collected. As a natural, cost-free gravity energy storage medium, it does not require gravity energy storage transportation and can be directly obtained. When solid energy storage blocks are used for gravity energy storage, they need to be transported from the low-level energy storage stack to the high-level energy storage stack by train for storage, which consumes a lot of electricity, as well as equipment operation and maintenance, and the gravity energy storage energy needs to be too large.

[0004] At present, there is a lack of application experience and technology specifically for generating electricity by storing water during the rainy season with the help of gravity energy storage rail transportation systems. Therefore, it is necessary to design a rail-type gravity energy storage transportation control system that is compatible with solid and liquid energy storage media. By collecting rainwater during the rainy season as a gravity energy storage medium, the energy consumption of transporting gravity energy storage blocks can be reduced. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a rail-type gravity energy storage transportation control system that is compatible with solid and liquid energy storage media, which can be compatible with solid and liquid energy storage media, ensure efficient water filling and drainage operations of the loading water tank, and reduce manual intervention through automatic drainage control, thereby improving the automation and reliability of the system.

[0027] Beneficial effects of the present invention:

[0028] 1. Compatible with solid and liquid energy storage media for rail transport energy storage and power generation

[0029] The rail-type gravity energy storage transportation control system designed in this scheme is compatible with solid and liquid energy storage media, and can realize the flexible use of various energy storage forms. The loading tank system can store rainwater or other liquid energy storage media, making full use of the gravitational potential energy of rail transportation. It can be used as a transportation and storage system for liquid energy storage media, and can also be used for the transportation of solid energy storage media to meet different energy storage and power generation functions. The flexibility of the energy storage system makes this scheme highly adaptable and extensible in the application of different energy storage media.

[0030] During the rainy season, a large amount of rainwater is collected through reservoirs as a natural, cost-free gravity energy storage medium. It can be directly obtained without gravity energy storage transportation. This reduces the large amount of electricity consumed by solid energy storage units for gravity energy storage. At the same time, using rainwater as a gravity energy storage medium, during power generation and transportation, there is no need for complex clamping, unloading and stacking. After power generation is completed, it can be directly discharged and unloaded while transporting, reducing the low-level unloading process and further reducing power consumption.

[0031] 2. Ensure effective drainage operation of the loading tank

[0032] In terms of drainage operation, the design of the drainage assembly ensures that stable drainage control can be achieved through the cooperation of the stop valve and the lock joint. Through the ingenious layout of the lock groove, the drive shaft and the universal joint, power transmission can be achieved between adjacent flatbed carriages, ensuring that each water tank can be drained smoothly;

[0033] This scheme uses a purely mechanical locking mechanism design to control the opening and closing of the drainage component instead of an electronic valve design. This is mainly because gravity energy storage transportation systems are generally used in mining areas and solid waste bulk material areas, and are mostly open-air. Therefore, whether it is a transport train or a loading tank, the use of electronic components and other wearing parts is minimized as much as possible. Therefore, the mechanical locking mechanism of the drainage component in this scheme adopts a purely mechanical structure design. On the one hand, it adapts to the needs of the gravity energy storage environment, and on the other hand, it increases the service life of the drainage component opening and closing control and ensures drainage stability.

[0034] 3. Realize automatic operation of loading water tank drainage

[0035] In this scheme, the design of the drive assembly and the torque converter can automatically control the operation of the drainage assembly under triggering conditions. When the flatbed car passes a specific position, the action plates A and B can trigger the operation of the drive wheels, and transmit power to the drainage assembly through the torque converter, thereby automatically opening or closing the stop valve to achieve automatic drainage of the loading tank. The flexible transmission effect of the torque converter ensures operational stability while effectively avoiding damage caused by excessive impact or power transmission.

[0036] This automated control system reduces manual intervention, improves drainage efficiency and reliability, and is particularly suitable for scenarios with long-term automated operation, greatly improving the system's work efficiency and management convenience.

[0037] 4. Optimize space utilization, avoid interference, and improve transportation efficiency

[0038] This solution pays special attention to the spatial coordination and utilization of various components during transportation. Through the rationally designed clearance trough, the drainage components can be accurately docked when the water tanks are stacked, avoiding the spatial interference between the water tanks loaded at different levels. Through the spacing design between the driving wheels, transmission wheels and action plates, the possible collision or blockage during transportation is reduced, optimizing the transportation efficiency.

DETAILED DESCRIPTION

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0058] See also Figure 1-Figure 3 A rail-type gravity energy storage transport control system compatible with solid and liquid energy storage media, comprising a master controller, a transport train, a high-position gravity energy storage station, a low-position gravity energy storage station, a rainy season reservoir 13, and a transport track 14 connecting the high-position gravity energy storage station and the low-position gravity energy storage station to form a loop, wherein the high-position gravity energy storage station and the rainy season reservoir 13 are arranged higher than the low-position gravity energy storage station, and a power station 52 is arranged on the down track section of the transport track 14;

[0059] The transport train enters the power station 52 via the transport track 14 after being loaded from the high-level gravity energy storage station, converts the gravitational potential energy into kinetic energy for power generation and storage, then transports to the low-level gravity energy storage station for unloading, and returns to the high-level gravity energy storage station empty, thus forming a power generation and transportation line;

[0060] The high-position gravity energy storage station is stacked with solid energy storage units 3 and loading water tanks 4. The loading water tanks 4 are used to load the accumulated water in the rainy season reservoir 13. A drainage assembly 42 is installed at the bottom of the loading water tank 4. A mechanical locking mechanism for opening and closing the drainage assembly 42 is provided at the bottom of the transport train. The mechanical locking mechanism includes a transmission assembly and a drive assembly installed at the bottom of the transport train. The transmission assembly is linked to the drainage assembly 42, and the drive assembly is dynamically connected to the transmission assembly. A trigger is provided on the transport track 14. When the trigger is triggered, the drive assembly drives the transmission assembly to control the opening and closing posture of the drainage assembly 42.

[0061] The opening and closing control of the drainage component 42 adopts a pure mechanical locking mechanism design rather than an electronic valve design. This is mainly because gravity energy storage transportation systems are generally used in mining areas and solid waste bulk material areas, most of which are open-air. Therefore, whether it is a transport train or a loading water tank, the use of electronic components and other wearing parts is minimized as much as possible. Therefore, the mechanical locking mechanism of the drainage component 42 in this solution adopts a pure mechanical structure design. On the one hand, it adapts to the requirements of the gravity energy storage environment, and on the other hand, it increases the service life of the opening and closing control of the drainage component and ensures drainage stability.

[0062] A liquid level sensor is installed in the rainy season water reservoir 13, and the liquid level sensor is electrically connected to the main controller. The main controller controls the high-level gravity energy storage station to select the solid energy storage unit 3 or the loading water tank 4 as the gravity energy storage medium to enter the power generation transportation line according to the water level detected by the liquid level sensor.

[0063] When the gravity energy storage medium is the loading water tank 4, after the transport train goes down with load and the energy is converted by the power station 52, the mechanical locking mechanism at the bottom of the transport train is triggered to open the drainage component 42 to drain water. After the loading water tank 4 is transported upward with no load, the mechanical locking mechanism locks the drainage component 42, and the transport train returns to the high-position gravity energy storage station.

[0064] The technical solution provided in this application is mainly suitable for geographical environments with height differences. It relies on the mountain terrain structure and realizes energy storage cycle through the mutual conversion of gravitational potential energy and electrical energy. It can be used as a high-safety, low-cost large-scale, long-term energy storage system to achieve peak shaving and valley filling of the power grid, and can also smooth out the volatility of wind and solar power generation.

[0065] The rail-type gravity energy storage transportation control system designed in this scheme is compatible with solid and liquid energy storage media, and realizes the flexible use of various energy storage transportation forms. By loading the water tank 4, rainwater or other liquid energy storage media can be stored, and the gravitational potential energy of rail transportation can be fully utilized. It can be used as a transportation and storage system for liquid energy storage media, and can also be applied to the transportation of solid energy storage media, meeting the energy storage and power generation functions of different needs. The flexibility of the energy storage system makes this scheme highly adaptable and expansible in the application of different energy storage media.

[0066] During the rainy season, a large amount of rainwater is collected through reservoirs as a natural, cost-free gravity energy storage medium. It can be directly obtained without gravity energy storage transportation. This reduces the large amount of electricity consumed by solid energy storage units for gravity energy storage. At the same time, using rainwater as a gravity energy storage medium, during power generation and transportation, there is no need for complex clamping, unloading and stacking. After power generation is completed, it can be directly discharged and unloaded while transporting, reducing the low-level unloading process and further reducing power consumption.

[0067] The transport track 14 includes a high-level track 141, a low-level track 142, an upward track 143, and a power generation track 144. The high-level track 141 and the low-level track 142 are respectively arranged at the positions of the high-level gravity energy storage station and the low-level gravity energy storage station. The upward track 143 and the power generation track 144 are both connected to the high-level track 141 and the low-level track 142. The power station 52 is arranged along the power generation track 144.

[0068] The transport train includes a plurality of connected flatbed carriages 2, which are used for fixing solid energy storage units 3 or loading water tanks 4. A transmission assembly is installed at the bottom of each group of flatbed carriages 2, and the transmission assemblies installed in two adjacent groups of flatbed carriages 2 maintain power connection. A drive assembly is installed at the bottom of one group of flatbed carriages 2, and the drive assembly maintains power connection with the corresponding transmission assembly. A trigger member for triggering the drive assembly is provided at one end of the high-level rail 141 close to the upward rail 143 and one end of the low-level rail 142 close to the power generation rail 144.

[0069] When electricity consumption is low or new energy generation is sufficient, the master controller controls the transport train to enter the gravity energy storage transport line. The flatbed carriage 2 in the transport train is loaded with the solid energy storage unit 3 of the low-level gravity energy storage station and driven by the driving station 51, so that the transport train runs along the low-level rail 142, the upward rail 143, and the high-level rail 141. The driving station 51 is powered by the power grid and uses the motor to transfer the solid energy storage unit 3 and the transport train to the high-level gravity energy storage station to realize the conversion of electric energy to gravitational potential energy. The solid energy storage unit 3 transported to the high-level gravity energy storage station can be unloaded from the flatbed carriage 2 and stacked. When the conversion of electric energy to gravitational potential energy is continuously carried out, the unloaded flatbed carriage 2 can run along the high-level rail 141, the power generation rail 144, and the low-level rail 142 to the low-level gravity energy storage station. The flatbed carriage 2 running to the low-level gravity energy storage station can be loaded with the solid energy storage unit 3 there again to continuously convert electric energy to gravitational potential energy.

[0070] During peak electricity consumption or when new energy generation is insufficient, the master controller controls the high-level gravity energy storage station to select the solid energy storage unit 3 or the loading water tank 4 as the gravity energy storage medium to enter the power generation transportation line according to the water level detected by the liquid level sensor.

[0071] When the water level detected by the liquid level sensor is lower than the set threshold, the main controller controls the high-level gravity energy storage station to select the solid energy storage unit 3 as the gravity energy storage medium to enter the power generation transportation line, and the flatbed carriage 2 in the transport train travels to the loading and unloading area, and the solid energy storage unit 3 of the high-level gravity energy storage station is loaded onto the flatbed carriage 2, and enters the power generation rail 144 under the driving action of the driving station 51, and continues to run along the power generation rail 144 and the low-level rail 142. The power station 52 installed on the power generation rail 144 can convert the gravitational potential energy released by the transport train and the solid energy storage unit 3 into electrical energy, and the solid energy storage unit 3 transported to the low-level gravity energy storage station is unloaded from the flatbed carriage 2 and stacked, and the empty flatbed carriage 2 is driven by the driving station 51 to go up along the low-level rail 142, the upward rail 143, and the high-level rail 141 to the high-level gravity energy storage station, and the solid energy storage unit 3 is reloaded here to continue the conversion of gravitational potential energy into electrical energy.

[0072] When the water level detected by the liquid level sensor is higher than the set threshold, the main controller controls the high-level gravity energy storage station to select the loading water tank 4 as the gravity energy storage medium to enter the power generation transportation line, and the flatbed carriage 2 in the transport train travels to the water injection station 113, and the stacked loading water tanks 4 of the high-level gravity energy storage station are loaded and fixed on the flatbed carriage 2, and then the rainwater collected in the rainy season reservoir 13 is pumped into the loading water tank 4 through the water injection pipe 1113, and under the driving action of the driving station 51, the transport train enters the power generation rail 144 from the high-level rail 141, and continues to run along the power generation rail 144 and the low-level rail 142 The power station 52 installed on the power generation rail 144 can convert the gravitational potential energy released by the transport train, the loading water tank 4 and rainwater into electrical energy. When it runs to the low-level rail 142, the trigger component triggers the driving component to drive the transmission component to open the drainage component 42 of the loading water tank 4 to discharge the stored rainwater. The driving station 51 drives the transport train and the empty loading water tank 4 along the low-level rail 142 and the upward rail 143 to the high-level rail 141, and the trigger component triggers the driving component to drive the transmission component to lock the drainage component 42, enter the high-level gravity energy storage station, and refill with rainwater for cyclic power generation.

[0073] It should be noted that water diversion channels can be dug on both sides of the low-level rail 142, and rainwater discharged from the water tank 4 can enter the water diversion channel and be discharged uniformly. Example

[0074] See also Figure 1 In order to ensure that the solid energy storage unit 3 and the loading water tank 4 can be stably stacked and placed at the high-position gravity energy storage station or the low-position gravity energy storage station, and realize the loading and unloading on the loading train, and at the same time facilitate the filling of the loading water tank 4 at the high-position gravity energy storage station, the following technical solution is provided.

[0075] The high-level gravity energy storage station is equipped with several groups of high-level stacking stacks A111, high-level stacking stacks B112, and water filling stations 113. The high-level stacking stack A111 is used to stack and stack the solid energy storage units 3, and the high-level stacking stack B112 is used to stack and stack the loading water tanks 4. The low-level gravity energy storage station is equipped with several groups of low-level stacking stacks 121. The high-level rail 141 includes multiple loading and unloading rails A147 passing through each high-level stacking stack A111, high-level stacking stack B112, and water filling station 113, and the low-level rail 142 includes multiple loading and unloading rails B148 passing through each low-level stacking stack 121.

[0076] The high-position stacking stack A111 and the high-position stacking stack B112 can respectively stack, stack and load and unload the solid energy storage unit 3 and the loading water tank 4 between the flatbed carriage 2 and the high-position gravity energy storage station, and the water filling station 113 can fill the loading water tank 4 loaded onto the flatbed carriage 2 with water.

[0077] The low-level stacking stack 121 can stack, stack, load and unload the solid energy storage units 3 between the flatbed carriage 2 and the low-level gravity energy storage station.

[0078] In order to achieve unified control of the transportation management of the entire system and improve the degree of automation of system operation, the following technical solutions are provided.

[0079] The main controller is connected with the liquid level sensor, the high-position palletizing stack A111, the high-position palletizing stack B112, the water injection station 113, the low-position palletizing stack 121, the driving station 51, and the power station 52 by signals.

[0080] The main controller can regulate the operating states of the high-position stacking stack A111, the high-position stacking stack B112, the water filling station 113, the low-position stacking stack 121, the driving station 51, and the power station 52 to ensure that the solid energy storage unit 3 and the loading water tank 4 can be stably stacked and stably loaded and unloaded to the flatbed carriage 2, and the accumulated rainwater can be stably filled into the loading water tank 4. When the liquid level sensor detects that the water level in the rainy season water reservoir 13 meets the set threshold, the water filling station 113 can be used to fill the loading water tank 4 and perform the power generation and transportation mode.

[0081] The master controller can also control the operating status of the power station 52 and the drive station 51 to achieve control over the operation of the transport train and the power generation of gravitational potential energy. Example

[0082] See also Figure 4-Figure 6 In order to ensure that the solid energy storage unit 3 and the loading water tank 4 can be stacked and placed stably, and to ensure that the solid energy storage unit 3 and the loading water tank 4 can be stably assembled on the flatbed carriage 2, the following technical solution is provided.

[0083] The corners of the solid energy storage unit 3 and the loading water tank 4 are equipped with locking and positioning assemblies 7. The locking and positioning assemblies 7 include a positioning shaft A71, an assembly column 72, and a positioning sleeve 73 fixedly connected in sequence from top to bottom. The assembly column 72 is fixedly installed in the solid energy storage unit 3 and the loading water tank 4. The positioning shaft A71 extends to the top of the solid energy storage unit 3 and the loading water tank 4. The positioning sleeve 73 is flush with the bottom of the solid energy storage unit 3 and the loading water tank 4. The positioning shafts A71 and positioning sleeves 73 in different locking and positioning assemblies 7 can be nested and plugged in.

[0084] The locking and positioning assembly 7 also includes a lifting guide rod 74, a driving key 75, and a locking key 76. The lifting guide rod 74 is slidably installed in the positioning shaft A71, the assembly column 72, and the positioning sleeve 73. The outer edge of the positioning shaft A71 is provided with a locking groove A711 and a clamping groove 712. The driving key 75 includes two groups of slidingly installed in the positioning shaft A71 and maintained in a symmetrical arrangement. The driving key 75 is exposed in the clamping groove 712. The driving key 75 is hinged with the lifting guide rod 74 through a connecting rod 751. The shaft A71 is internally equipped with a support spring A713 which is maintained in contact with the lifting guide rod 74. The locking key 76 is slidably installed in the positioning sleeve 73 and includes multiple groups of evenly distributed ones. The locking key 76 can be nested and snap-fitted with the locking groove A711. The inner side of the positioning sleeve 73 is equipped with a support spring B731 which is nested and abutted with the locking key 76. A wedge block A761 is fixedly connected to the locking key 76. The bottom end of the lifting guide rod 74 is fixedly connected with a wedge block B741 which abuts against the wedge block A761.

[0085] A positioning shaft B23 which is nested and matched with the positioning sleeve 73 is fixedly connected to the corner of the flatbed carriage 2, and a locking groove B231 which is nested and locked with the locking key 76 is formed on the positioning shaft B23.

[0086] When the solid energy storage units 3 and the loading water tanks 4 are stacked, the positioning sleeves 73 in the locking and positioning assemblies 7 on the upper solid energy storage units 3 and the loading water tanks 4 can be nested and plugged with the positioning shafts at the top of the lower locking and positioning assemblies 7, and can be nested and snapped together by the locking keys 76, thereby realizing a fixed combination of two adjacent layers of fixed energy storage units or loading water tanks 4.

[0087] The positioning shaft A71 in the locking and positioning assembly 7 is clamped with the help of the high-position stacking stack A111, the high-position stacking stack B112, and the low-position stacking stack 121. Specifically, the matching clamping plate 15 is clamped and positioned with the clamping groove 712. An arc-shaped clearance groove 151 is also provided on the clamping plate 15, which can be locked with the clamping groove and can push the driving key 75 back into the positioning shaft A71. In the process of retracting the driving key 75, the lifting guide rod 74 can be driven upward through the connecting rod 751, and the support spring A713 is compressed. The upward lifting guide rod 74 can be driven by the cooperation of the wedge block A761 and the wedge block B741. The locking key 76 at the bottom of the movement is retracted, and when the locking key 76 is retracted, the positioning sleeve 73 can be plugged into and combined with the positioning shaft A71 or the positioning shaft B23 below. When the clamp 15 is canceled, the support spring A713 can drive the guide rod to descend and make the drive key 75 slide outward to reset. At this time, the wedge block B741 cancels the effect on the wedge block A761, and the locking key 76 can slide out under the action of the support spring B731B and be nested and locked with the locking grooves A711 and B231 on the positioning shaft A71 and the positioning shaft B23, thereby realizing the stacking and stacking of the solid energy storage unit 3 and the loading water tank 4 or the loading and unloading to the flatbed carriage 2. Example

[0088] See also Figure 7-Figure 12 In order to facilitate the filling of rainwater collected in the rainy season reservoir 13 into the loading water tank 4, a water inlet 411 is opened on the top of the loading water tank 4, and an inward-turned cover plate 412 is hinged on the inner side of the water inlet, and a tension spring is connected between the cover plate and the water inlet. Under the action of the tension spring, the cover plate can be pulled up and reset to achieve the blocking of the water inlet.

[0089] The water filling station 113 is equipped with a water filling pipe that can move vertically. After the water filling pipe is against the cover plate in the water inlet and pushes it open, the water filling pipe enters the loading water tank 4, and the rainwater in the rainy season water reservoir 13 is injected into the loading water tank 4 through the water filling pipe by a water pump.

[0090] A pressure balancing valve can also be installed at the water inlet to ensure that the internal air pressure of the rainwater in the water tank 4 is always equal to the external environmental air pressure during the drainage and water filling stages, thereby ensuring stable water filling and drainage.

[0091] In order to ensure that the drainage assembly 42 can be stably installed at the bottom of the loading water tank 4 and will not cause spatial interference with the lower loading water tank 4 and flatbed carriage 2 during the stacking of the loading water tank 4 and loading on the flatbed carriage 2, the following technical solution is provided.

[0092] The drainage assembly 42 includes a stop valve 421 and a locking joint 422. The stop valve 421 is fixedly installed at the bottom of the loading water tank 4, and the locking joint 422 is rotatably installed at the bottom of the loading water tank 4. A bevel gear A4211 is fixedly connected to the shaft of the stop valve 421, and a bevel gear a4221 that meshes with the bevel gear A4211 is coaxially fixedly connected to the locking joint 422. The locking joint 422 is linked to the transmission assembly. A recessed groove 43 is provided on the top of the loading water tank 4, and a make way opening 24 is provided on the flatbed carriage 2.

[0093] A drainage pipe is fixedly installed at the bottom of the flatbed carriage 2, and the drainage pipe includes a water receiving pipe 251 and a water diversion pipe 252. The water receiving pipe 251 is arranged vertically and sealed and plugged with the stop valve 421, and the water diversion pipe 252 is connected to both sides of the water receiving pipe 251.

[0094] The opening and closing posture of the stop valve 421 can be controlled by driving the rotation of the shaft of the stop valve 421. When the loading water tank 4 is assembled on the flatbed car 2, the drainage assembly 42 is just arranged in the make way opening 24, and the sealing connection between the stop valve 421 and the water receiving pipe 251 is realized, thereby realizing the linkage combination of the locking joint 422 and the transmission assembly below.

[0095] When the transmission component drives the lock joint 422 to operate, the shaft of the stop valve 421 can be driven to rotate through the combination of the bevel gear a4221 and the bevel gear A4211, thereby controlling the opening and closing of the stop valve 421. When the stop valve 421 is opened, rainwater in the loading water tank 4 can be discharged through the water receiving pipe 251 and the water diversion pipe 252. The setting of the water diversion pipe 252 can guide the rainwater to both sides of the transport track 14 to prevent the rainwater from directly eroding the transport track 14.

[0096] When the loading water tanks 4 are stacked, the drainage assembly 42 at the bottom of the upper loading water tank 4 can be located in the yielding trough 43 at the top of the lower loading water tank 4, thereby ensuring that there is no spatial interference between the two adjacent loading water tanks 4. Example

[0097] See also Figure 12-Figure 17 In order to ensure that the transmission assembly can be stably installed at the bottom of the flatbed carriage 2 and realize linkage combination with the locking joint 422, and to ensure that the transmission assemblies on the two adjacent sets of flatbed carriages 2 are dynamically connected, the following technical solution is provided.

[0098] The transmission assembly includes a transmission shaft 211, a universal joint A212, a universal joint B213, and a locking groove 214. The transmission shaft 211 is rotatably mounted at the bottom of the flatbed carriage 2 and arranged along the length direction of the flatbed carriage 2. The driving assembly maintains a power connection with the transmission shaft 211. The ends of the transmission shaft 211 are respectively equipped with universal joints A212 and B213. The universal joints A212 and B213 are respectively rotatably mounted at the front and rear sides of the flatbed carriage 2. On the hanging component 26, the outer end of the universal joint A212 is fixedly connected to the spline shaft 2121, the outer end of the universal joint B213 is fixedly connected to the spline sleeve 2131 matched with the spline shaft 2121, the locking groove 214 is rotatably installed on the flatbed carriage 2 and is nested and plugged with the locking head 422, a bevel gear B2111 is fixedly connected to the transmission shaft 211, and the locking groove 214 is coaxially fixedly connected to a bevel gear b2141 that is meshed with the bevel gear B2111.

[0099] When the transmission shaft 211 is driven by the driving assembly, the combination of the bevel gear B2111 and the bevel gear b2141 can drive the locking groove 214 to operate stably, and then the power is transmitted to the locking joint 422 through the combination of the locking groove 214 and the locking joint 422.

[0100] When each flatbed car 2 is connected and combined by a hook component, the spline shaft 2121 and the spline sleeve 2131 on two adjacent groups of flatbed cars 2 can be plugged in and combined to ensure stable transmission of power to the transmission components at the bottom of different flatbed cars 2. When the transport train runs to the curve of the transport track 14, the connecting components on the two adjacent groups of flatbed cars 2 can rotate with the curve to compensate for the inclination angle of each flatbed car 2 when the transport train turns. The rotation axis of the universal joint A212 and the universal joint B213 and the rotation axis of the connecting component are arranged in the same vertical direction to ensure that the spline shaft 2121 and the spline sleeve 2131 on the universal joint A212 and the universal joint B213 rotate synchronously with the connecting component, ensuring that power can be stably transmitted in any state.

[0101] In order to ensure that the drive assembly can be stably installed at the bottom of the flatbed carriage 2 and realize power connection with the corresponding transmission assembly, and to ensure that the high rail 141 and the low rail 142 of the drive assembly can be triggered and generate force, the following technical solution is provided.

[0102] The driving assembly includes a driving wheel 221, a hydraulic torque converter 222, a driving shaft 223, and a matching combination of a worm wheel 224 and a worm 225. The driving wheel 221, the driving shaft 223, and the worm 225 are all rotatably mounted on the bottom of the flatbed carriage 2. The driving wheel 221 and the driving shaft 223 are connected to each other through the hydraulic torque converter 222. A bevel gear C2231 is fixedly connected to the driving shaft 223. A bevel gear c2251 that meshes with the bevel gear C2231 is fixedly connected to the worm 225. The worm wheel 224 is fixedly connected to the transmission shaft 211.

[0103] like Fig.17 The triggering parts are action plates A145 and B146. Action plates A145 are fixedly connected to the high-level rail 141, and action plates B146 are fixedly connected to the low-level rail 142. When the driving wheel 221 passes through action plates A145 and B146, it fits with action plates A145 and B146. Action plates A145 and B146 are respectively arranged on both sides of the driving wheel 221.

[0104] When the flatbed carriage 2 is loaded with the water tank 4 and enters the low rail 142 after passing through the power rail to generate electricity, the driving wheel 221 is driven to run forward under the action of the action plate B146 on the low rail 142 to trigger the driving component, and the drainage component is driven to open the drainage through the transmission component. When the flatbed carriage 2 is loaded with the water tank 4 and enters the high rail 141 after passing through the upward rail, it acts with the action plate A145 on the high rail 141 to drive the driving wheel 221 to run in the reverse direction to trigger the driving component, and the drainage component is driven to close through the transmission component to perform the next batch of water injection operations.

[0105] Since the action plate A145 and the action plate B146 are respectively arranged on both sides of the driving wheel 221, when the driving wheel 221 acts on the action plate A145 and the action plate B146, the rotation direction generated by the driving wheel must be opposite. When the power is transmitted to the drainage component through the driving component and the transmission component, the stop valve can be controlled to be open and closed respectively.

[0106] When the driving wheel 221 is running, the power is transmitted to the driving shaft 223 through the torque converter 222, and then the worm 225 is driven to run stably through the combination of the bevel gear C2231 and the bevel gear c2251, so as to stably transmit the power to the worm wheel 224 and achieve deceleration and torque increase, so as to drive the transmission shaft 211 to run stably. When the transmission shaft 211 is running, it can drive the locking groove 214 and the locking joint 422 of the matching locking combination to run stably, so as to control the opening or closing of the stop valve.

[0107] In order to prevent the driving wheel 221 from still transmitting force to the transmission shaft 211 when the shut-off valve 421 is fully opened or closed, a hydraulic torque converter 222 is added to perform flexible power transmission. When the shut-off valve 421 is fully opened or locked, the power of the driving wheel 221 cannot be further transmitted to the transmission shaft 211 due to the action of the hydraulic torque converter 222.

[0108] In order to ensure that the drive station 51 and the power station 52 can effectively transmit or receive power while avoiding spatial motion interference with the assembled drive components, the following technical solutions are provided.

[0109] Two groups of action plates C27 arranged along the length direction of the flatbed carriage 2 are fixedly connected to the bottom of the flatbed carriage 2. The transmission wheel A511 on the driving station 51 is in contact with the inner side of the action plate C27, and the transmission wheel B521 on the power station 52 is in contact with the outer side of the action plate C27. The action plate C27 is arranged on both sides of the action plate A145 and the action plate B146, and the transmission wheel A511 and the transmission wheel B521 are arranged on both sides of the driving wheel 221.

[0110] The driving station 51 is driven by a motor to operate the transmission wheel A511. When the flatbed carriage 2 passes by, the inner side of the action plate C27 at the bottom can act on the transmission wheel A511, thereby transmitting the power of the transmission wheel A511 to the action plate C27 to drive the flatbed carriage 2 to move forward.

[0111] The transmission wheel B521 on the power station 52 is connected to the power of the generator. When the flatbed carriage 2 passes by, the outer side of the action plate C27 at the bottom can act on the transmission wheel B521, thereby driving the transmission wheel B521 to operate, and the generator converts kinetic energy into electrical energy.

[0112] The transmission wheel A511, the transmission wheel B521, and the driving wheel 221 are arranged at intervals, and the action plate A145, the action plate B146, and the action plate C27 are also arranged at intervals, which can effectively avoid spatial motion interference between the flatbed carriage 2 during operation.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
