Description

Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a step-up substation with energy storage. Background Art

[0002] A substation is a hub facility in the power system for transforming voltage, controlling current, and distributing electric energy. Through transformers, switchgear, protection devices, etc., it realizes the conversion, transmission, and distribution of electric energy to ensure the safe, stable, and efficient operation of the power system. Among them, a step-up substation is a substation in the power system for raising the voltage level. Due to complex terrain environments such as mountainous areas, traditional civil substations face challenges such as high construction difficulty, long cycle, and high cost. Especially when the construction site is frequently relocated, the power supply flexibility of fixed substations is difficult to meet the requirements. Therefore, most substations in mountainous areas and other places adopt mobile box-type substations, which are easy to install and can well adapt to the complex terrain in mountainous areas, providing stable and reliable power supply for industrial and mining enterprises such as factories and mines.

[0003] However, floods occur frequently in mountainous areas during the flood season. Floods not only have powerful destructive power themselves but also carry gravel, debris, etc., thus posing serious threats to mobile box-type substations in many aspects. Specifically, floods are not only likely to carry debris to impact the substation but also submerge and even wash away the substation when floods rage. As a key facility for power supply in mountainous areas, once damaged, the substation itself will not be able to operate normally, and it will also seriously affect the production of surrounding factories and the mining operations of mines, causing huge economic losses and poor practicability. Summary of the Invention

[0018] Preferably, a protective net is commonly installed between the two mobile hydraulic elevators.

[0019] Compared with the existing technology, the advantages of the present invention are as follows:

[0020] 1. Through the mutual cooperation of the mobile hydraulic elevator, the rotating lifting mechanism, the embedding nails, and the resisting and guiding mechanism, the present invention can not only fix the box-type substation by the downward movement and rotation of the embedding nails after moving the box-type substation, but also use the first baffle and the second baffle to resist and guide the flood and the operation of inflating and deflating the airbag when the flood comes to effectively buffer and block the direct impact of the flood, and resist the gravel and sundries in the flood, avoiding damage to the box-type substation due to the impact of the flood and the stones and sundries carried in the flood, and effectively ensuring the stability of the entire substation under the flood impact, and then effectively ensuring the normal operation of the box-type substation.

[0021] 2. Through the mutual cooperation of the embedding nails and the fixing mechanism, the present invention can not only make the grab hook smoothly embed into the soil layer by closing the second electromagnet, the downward movement of the embedding nails and the vibration of the vibration block during normal use, thereby improving the fixing effect of the embedding nails in the soil, but also use the buoyancy after the flood accumulates, the closing of the first electromagnet, the extension and rotation of the storage housing, the setting of the partition film on the storage housing, and the operation of injecting the chemical gel curing agent into the storage housing to form a uniform and tight curing layer between the storage housing and the soil when the flood comes and accumulates, so as to ensure that the mounting ring and the embedding nails can be firmly fixed in the soil, that is, effectively ensuring the stability of the entire substation after the flood comes, and then ensuring the normal operation of the box-type substation.

[0022] 3. Through the setting of the fixing mechanism, by controlling the opening and closing states of multiple solenoid valves, the present invention can form a dense protective layer composed of high-concentration curing agent on the water-facing side of the curing layer to resist the scouring of flood water. At the same time, the weight of the curing layer itself will generate a moment, which can skillfully offset the external moment generated by the water impact, thus ensuring that the entire substation is in a balanced stress state and effectively guaranteeing the stability of the entire substation. In addition, through the setting of the telescopic rod in the fixing mechanism, an elastic fixing system can be constructed, enabling the entire substation (except for the part fixed in the soil) to float due to the accumulation of flood water. Specifically, the telescopic rod can automatically adjust its length to adapt to the change of water level. This function of automatically adjusting the length, combined with the setting of the second electric telescopic rod and the fixing effect of the embedding nails and the installation ring, jointly forms a stable anchoring structure. This anchoring structure, combined with the setting of the airbag, can make the box-type substation float with the accumulation of flood water, thus avoiding the internal equipment of the substation from being affected by flood water and also preventing it from being washed away or submerged by flood water, effectively ensuring the normal operation of the box-type substation after the flood comes.

[0023] 4. Through the setting of the flood resistance and diversion mechanism, the present invention can not only use the multi-level water flow protection system constructed by the second baffle and the first baffle with adjustable angle to achieve the flood resistance, diversion and interception of gravel and sundries in the flood water, but also use the concave-shaped setting of the first baffle and the second baffle and the setting of multiple arc plates and multiple diversion strips on them to make the flood water achieve a smooth transition along the surfaces of the first baffle and the second baffle, thus effectively reducing the local impact pressure of the flood water on the first baffle and the second baffle, and further effectively guaranteeing the service life of the first baffle and the second baffle. In addition, the concave-shaped setting of the first baffle and the second baffle can be used to guide the gravel and sundries hitting them to roll to the ground and be carried away by the flood water flow, thus effectively reducing the accumulation of sundries in the surrounding area of the entire substation and reducing the potential safety hazards caused by the accumulation of gravel and sundries.

[0024] 5. Through the setting of the protective net between the two mobile hydraulic elevators, the present invention can not only prevent small animals such as snakes and rats from entering the box-type substation during normal use, effectively reducing the risk of short circuit of the internal equipment of the box-type substation caused by the entry of small animals, but also slow down the flood water flow speed and prevent the water flow from carrying small gravel and hitting the bottom of the box-type substation when the flood comes, thus avoiding affecting the normal operation of the box-type substation.

[0040] Refer to Figures 6 to 10, at the bottom ends of multiple installation shells 23, multiple first electromagnets 24 are fixedly embedded. And it is magnetically connected with an installation ring 25 through the multiple first electromagnets 24. At a position near the bottom end on the inner wall of the installation ring 25, a second electromagnet 41 is magnetically connected. An embedding nail 16 is installed at the bottom end of the second electromagnet 41. Both the installation shell 23 and the installation ring 25 are made of magnetic materials. A fixing mechanism is arranged inside the installation shell 23 and the installation ring 25 for enabling the embedding nail 16 to be firmly fixed in the soil.

[0041] Refer to Figures 8 to 10 , the auxiliary component includes a third mounting plate 29. The third mounting plate 29 is rotatably sleeved on the second electric telescopic rod 39, and a storage tank 42 is installed at its top end. Through holes for the telescopic rod 26 and the output end of the telescopic rod 26 to pass through are respectively provided at the middle positions of the top ends of the third mounting plate 29 and the storage tank 42. Multiple first electric telescopic rods 28 are evenly installed on the outer wall of the third mounting plate 29. The output ends of the multiple first electric telescopic rods 28 are all installed with storage shells 27. Multiple through holes are evenly formed on the outer wall of the storage shell 27. A separation membrane is installed in each through hole. The separation membrane is made of pullulan. Pullulan is a water-soluble polysaccharide with good solubility, so that the separation membrane can dissolve when contacting water flow. A chemical gel curing agent is placed inside the storage tank 42, and multiple telescopic hoses are installed on the storage tank 42. A solenoid valve is installed at the connection position of the telescopic hose and the storage tank 42. The telescopic hose and the solenoid valve are both prior arts, and their specific structural designs will not be elaborated here.

A driving component is arranged on the second electric telescopic rod 39 and the third mounting plate 29 for driving the third mounting plate 29 to rotate.

[0042] Refer to Figures 8 to 10, the driving component includes a fixing plate 32, a fixing ring 34 and a first gear 30. Both the fixing plate 32 and the fixing ring 34 are fixedly sleeved on the second electric telescopic rod 39. The bottom end of the fixing plate 32 is fixedly connected to the top end of the fixing ring 34. And a second motor 33 is installed at the bottom end of the fixing plate 32.

The first gear 30 and the second gear 31 are meshed with each other.

[0043] In the present invention, the mobile hydraulic lift 14 can drive the box-type substation 1 to move flexibly in the complex mountainous terrain, so that the box-type substation 1 can be quickly transported to the designated position. On the uneven ground in the mountains, compared with the conventional way of moving the box-type substation 1 as a whole, by controlling the two mobile hydraulic lifts 14 to directly drive the box-type substation 1 to move, it is less likely to tip over when the terrain is inclined, thus ensuring the stability of the box-type substation 1 during transportation. This effectively prevents the equipment from tipping over and being damaged due to jolts during transportation. Specifically, the conventional box-type substation 1 is usually installed on a fixed plate and moved as a whole through a moving device. This method is effective when the terrain is flat, but in the complex mountainous terrain or on the inclined ground, its moving stability is poor and it is easy to tip over during movement. And by controlling the two mobile hydraulic lifts 14, the height of the box-type substation 1 and the first mounting plate 6 can be adjusted, so that the box-type substation 1 can be lifted and its bottom can be kept at a certain distance from the ground, thus avoiding the negative impact of moisture accumulation on the ground due to its proximity to the ground. In addition, by adjusting the distance between the box-type substation 1 and the ground, the air circulation at the bottom of the box-type substation 1 can be effectively promoted. This air circulation helps to take away the heat generated at the bottom of the box-type substation 1 and prevent heat accumulation, thus being beneficial to the natural heat dissipation of the box-type substation 1.

[0044] After the box-type substation 1 is moved to a proper position by the mobile hydraulic lift 14, the second hydraulic rod 20 is activated to lower the second mounting plate 15 and the multiple mounting shells 23 at the bottom of the second mounting plate 15, thereby driving the multiple mounting rings 25 and the multiple embedding nails 16 to move downward. At the same time, the first motor 21 is activated to rotate the mounting shells 23, so that the mounting rings 25 and the embedding nails 16 rotate. As the embedding nails 16 move downward and rotate, the embedding nails 16 can continuously penetrate into the soil until the embedding nails 16 reach a predetermined depth. Then, the second hydraulic rod 20 and the first motor 21 are turned off. At this time, the bottoms of the flow guide plate 2, the first baffle 7, the second baffle 8, the first fixed shell 3, the second fixed shell 9, the third fixed shell 11 and the second mounting plate 15 will contact the soil surface, thus increasing the stress area of the entire substation. This not only disperses the pressure in the vertical direction but also enhances the stability of the box-type substation 1 when subjected to external forces.

[0045] After the embedding nails 16 reach a predetermined depth, the second electromagnet 41 is turned off (in the normal state, the first electromagnet 24 and the second electromagnet 41 are both in the on state). Then, the second electric telescopic rod 39 is controlled to drive the embedding nails 16 to continue to penetrate downward (at this time, a gap will be generated between the embedding nails 16 and the mounting rings 25 and gradually become larger). Since the fourth mounting plate 35 is fixedly sleeved on the output end of the second electric telescopic rod 39, as the embedding nails 16 move downward, the grab hooks 37 will also move downward and extend from the gap between the embedding nails 16 and the mounting rings 25. Under the elastic action of the spring 38, the grab hooks 37 always maintain the extended state and deeply embed into the surrounding soil. At the same time, the vibration block 40 is activated, so that the embedding nails 16, the second electric telescopic rod 39 and the grab hooks 37 all start to vibrate. This can make the grab hooks 37 penetrate the soil more smoothly during the extension process and make the grab hooks 37 easier to embed into the soil layer, thereby significantly improving the grabbing force and effectively improving the fixing effect of the embedding nails 16 in the soil, that is, improving the stability of the box-type substation 1. After the embedding nails 16 penetrate downward for a certain distance, the control of the second electric telescopic rod 39 is stopped, and at the same time, the vibration block 40 continues to vibrate and stops after a period of time. Through the vibration of the vibration block 40, the soil particles are redistributed and tightly compacted. This process significantly improves the compactness of the soil. This not only increases the friction between the grab hooks 37 and the soil, ensuring that the grab hooks 37 embedded in the soil are not easily detached, but also improves the overall bearing capacity and stability of the soil, thereby further improving the stability of the box-type substation 1.

[0046] In mountainous areas, flood disasters occur frequently. Floods not only have powerful destructive power themselves but also carry gravel, debris, etc., posing serious threats to mobile substations in various aspects. Therefore, when the box-type substation 1 is moved and fixed in a suitable position, it is necessary to ensure that the orientations of the first baffle 7 and the second baffle 8 correspond to the direction of the approaching flood as much as possible according to the terrain difference. When a flood occurs, the ultrasonic water level sensor 18 is used to detect the water level, and at the same time, the acoustic Doppler current profiler 19 is used to accurately detect the direction of the flood. When the water level is not high (i.e., the flood flow is small), the first baffle 7, the second baffle 8, and the diversion plate 2 can be used to resist and divert the water flow first. By dispersing the water flow energy, the damage caused by direct impact to the box-type substation 1 can be reduced. Subsequently, the inflation and deflation device 4 is controlled to inflate the airbags 13 in the first fixed housing 3, the second fixed housing 9, and the third fixed housing 11.

[0047] If the acoustic Doppler current profiler 19 detects that the main approaching direction of the flood corresponds to the position of the first baffle 7, the airbag 13 inside the third fixed housing 11 is inflated preferentially at this time. Thus, through the mutual cooperation of the airbag 13 inside the third fixed housing 11 and the first baffle 7, the direct impact of the flood can be effectively buffered and blocked, reducing the negative impact of the flood on the rear area of the entire substation, thereby achieving flood prevention for the box-type substation 1. Subsequently, the airbags 13 inside the second fixed housing 9 and the first fixed housing 3 are gradually inflated, thus forming a stepped flood resistance structure. This structure can gradually slow down the water flow speed and disperse the water flow pressure, thereby effectively improving the flood prevention quality.

[0048] If the acoustic Doppler current profiler 19 detects that the main approaching direction of the flood corresponds to the position of the first baffle 7 and a certain second baffle 8 (i.e., the main approaching direction of the flood is relatively inclined), the airbags 13 inside the third fixed housing 11 and the corresponding second fixed housing 9 are inflated preferentially, and through the mutual cooperation of the airbags 13, the first baffle 7, and the second baffle 8, the direct impact of the flood can be effectively buffered and blocked. Subsequently, the airbags 13 inside the first fixed housing 3 and the remaining second fixed housing 9 are gradually inflated to form a stepped flood resistance structure again, achieving the purpose of gradually slowing down the water flow speed, dispersing the water flow pressure, and improving the flood prevention quality. During the above flood impact, the electronic tilt sensor 5 detects the stability of the entire substation in real time and controls the inflation and deflation operation of the airbag 13 by the inflation and deflation device 4 according to the detection data, thus effectively ensuring the stability of the entire substation under flood impact.

[0049] As the floodwater continues to accumulate, its flow rate will gradually increase, and the buoyancy force acting on the entire substation will also start to increase. At this time, the first electromagnet 24 is turned off. The installation housing 23 will move upward along with the box-type substation 1 and the first mounting plate 6 due to the increasing buoyancy force and the setting of the airbag 13, and will be separated from the mounting ring 25. After the installation housing 23 is separated from the mounting ring 25 by a certain distance, the first electric telescopic rod 28 is controlled to push out the storage housing 27. At the same time, the second motor 33 is started to make the second gear 31 rotate, so that the first gear 30 and the third mounting plate 29 connected to the first gear 30 rotate synchronously, and thus the storage housing 27 rotates while extending. At the same time, the solenoid valve is opened, and the chemical gel curing agent in the storage tank 42 enters the storage housing 27 through the telescopic hose.

[0050] Since the partition membrane in the through hole of the storage housing 27 is made of pullulan, when the partition membrane comes into contact with the moisture in the soil, the chemical gel curing agent in the storage housing 27 will be slowly released as the partition membrane gradually dissolves. This controlled release mechanism effectively avoids the rapid release and consumption of the chemical gel curing agent, prolongs its action time, and can also prevent the phenomenon of rapid soil solidification caused by the rapid release of the chemical gel curing agent, thus ensuring that the storage housing 27 can rotate continuously and stably. During the slow release of the curing agent, the rotation of the storage housing 27 enables the chemical gel curing agent to be fully and dynamically mixed with the soil particles, forming a uniform solidified layer (at this time, the second motor 33 is in the off state). This dynamic mixing method helps to break the aggregate structure of the soil, promotes the deeper penetration of the chemical gel curing agent into the pores of the soil, enables the curing agent to bind more tightly to the soil, and thus ensures that the mounting ring 25 and the embedding nails 16 can be firmly fixed in the soil, effectively guaranteeing the stability of the entire substation after the flood.

[0051] In addition, after a uniform solidified layer is formed (i.e., after the storage housing 27 stops rotating), by controlling the opening and closing states of multiple solenoid valves, it is ensured that the chemical gel curing agent can be continuously input into the storage housing 27 corresponding to the direction of the incoming flood, and at the same time, the delivery of the chemical gel curing agent in the remaining storage housing 27 is stopped. As a result, a dense protective layer composed of a high-concentration curing agent can be formed on the water-facing side of the solidified layer to resist the scouring of the flood water. At the same time, the weight of the solidified layer itself will generate a moment, which can skillfully offset the external moment generated by the water flow impact, thereby ensuring that the entire substation is in a balanced state in terms of force. Since the telescopic rod 26 is installed on the inner top wall of the installation housing 23 and the output end of the telescopic rod 26 is connected to the second electric telescopic rod 39, an elastic fixing system can be constructed through the telescopic rod 26, enabling the entire substation (except the part fixed in the soil) to float due to the accumulation of flood water. Specifically, the telescopic rod 26 can automatically adjust its length to adapt to the change in water level. This function of automatically adjusting the length, combined with the setting of the second electric telescopic rod 39 and the fixing effect of the embedding nails 16 and the installation ring 25, jointly form a stable anchoring structure. This anchoring structure, combined with the setting of the airbag 13, enables the box-type substation 1 to float with the accumulation of flood water, thereby being able to avoid the internal equipment being affected by the flood while also preventing it from being washed away or submerged by the flood, effectively ensuring the normal operation of the box-type substation 1 after the flood arrives.

[0052] The first baffle 7 and the second baffle 8 can not only disperse the water flow pressure but also resist the gravel and debris in the flood. Through the angle adjustment of the first baffle 7 and the fixed support of the second baffle 8, a multi-level water flow protection system can be constructed to achieve pressure dispersion, gravel interception, and the improvement of the structural stability of the entire substation. Under normal circumstances, the first baffle 7 is in a properly inclined state under the pushing action of the first hydraulic rod 12 (at this time, the first baffle 7 is inclined outward). When the gravel and debris in the flood hit the inclined first baffle 7, they will change their original movement direction during the rebound process, thereby being able to disperse the impact energy in multiple directions, thus reducing the direct impact on the baffle. (Compared with simple vertical rebound, such a setting can more effectively reduce the consumption of impact kinetic energy), thereby effectively improving the protection effect on the entire substation. In addition, the properly inclined first baffle 7 can disperse part of the impact force to the horizontal direction, reducing the force in the vertical direction, effectively ensuring the stability of the entire substation under the flood impact.

[0053] When the impact of gravel and debris is relatively large, the inclination angle of the first baffle 7 can be appropriately increased by controlling the first hydraulic rod 12, that is, making the first baffle 7 closer to the vertical direction, so as to enhance the rebound and friction effects, disperse the impact energy in multiple directions, and thus reduce the direct impact on the box-type substation 1. When the impact of gravel is relatively small, the inclination angle can be appropriately reduced. At this time, the kinetic energy of the gravel can be effectively consumed through appropriate friction, without relying on too strong a rebound effect. This can reduce the stress concentration degree of the first baffle 7 when it is impacted, and thus extend the service life of the first baffle 7.

[0054] Moreover, since the outer sides of both the first baffle 7 and the second baffle 8 are concave, and there are multiple arc plates and multiple guide strips 22 provided thereon, a multi-segment continuous arc surface structure can be jointly constructed. This arc surface structure enables the water flow to achieve a smooth transition along the surfaces of the first baffle 7 and the second baffle 8, effectively reducing the local impact pressure of the water flow on the first baffle 7 and the second baffle 8, effectively ensuring the service life of the first baffle 7 and the second baffle 8. At the same time, the concave settings of the first baffle 7 and the second baffle 8 can guide the gravel and debris hitting them to roll to the ground, and under the natural flow of the flood water, take away the above-mentioned gravel and debris, thus effectively reducing the accumulation of debris in the surrounding area of the entire substation and reducing the potential safety hazards caused by the accumulation of gravel and debris. In addition, since a protective net 17 is jointly installed between the two mobile hydraulic elevators 14, therefore, under the action of the protective net 17, it can prevent small animals such as snakes and rats from entering the box-type substation 1 during normal use, effectively reducing the risk of short circuits of the internal equipment of the box-type substation 1 due to the entry of small animals, and can also slow down the flood water flow speed when the flood comes, and prevent the water flow from carrying small gravel and hitting the bottom of the box-type substation 1, thus avoiding affecting the normal operation of the box-type substation 1.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
