Abstract
Description
Technical Field
[0001] This invention relates to the technical field of floating bridge erection equipment for pumped storage power stations, and particularly to a floating bridge erection system for pumped storage power stations. Background Technology
[0002] Pumped storage hydroelectric power stations were developed to address the supply and demand imbalance between peak and off-peak periods in the power grid. They are a method of indirectly storing electrical energy. They utilize excess electricity during the latter half of the night to drive pumps, drawing water from a lower reservoir to an upper reservoir for storage. The water is then released during the day and early night of the following day to generate electricity, and the water flows back into the lower reservoir.
[0003] Building a floating bridge over a reservoir would be a particularly spectacular sight. Pumped storage power stations have large reservoir areas, so the floating bridges spanning the water would have to be very long. The conventional way to build a floating bridge is for workers to assemble it on the water by boat, which is labor-intensive and inefficient. Moreover, due to the presence of wind and waves, manual construction poses safety risks. Summary of the Invention

Limiting plates 402 are provided on the top of both sides of the end of the sliding groove away from the bridge plate temporary storage rack 2.
[0057] A T-shaped slider 403 is provided on one end of the sliding bar 401 that extends outward from the through groove near the bridge plate temporary storage rack 2.
[0058] A vertical T-shaped groove 104 is provided at the bottom of the side wall of the fixed platform 1, and the T-shaped slider 403 slides and matches the T-shaped groove 104.
[0059] The distance from the side of the pressure plate 9 facing the fixed platform 1 to the farthest end of the through groove of the bridge plate temporary storage rack 2 is greater than the length of a bridge plate 5.
[0060] When the electric push rod 312 retracts, the distance from the bottom of the push plate 8 to the bottom of the conveyor track 4 is greater than the thickness of a bridge plate 5.
[0061] The top of the fixed platform 1 is provided with several steps 101. The bottom of the fixed platform 1 away from the bridge plate temporary storage rack 2 is provided with a fixed base plate 102. The fixed base plate 102 has several threaded holes at one end. The fixed base plate 102 is fixedly connected to the ground by bolts.
[0062] Several counterweight plates 103 are provided on the upper surface of the fixed base plate 102.
[0063] A rectangular groove 503 is provided in the middle of one end of the bridge plate 5, and a rectangular block 504 is provided in the middle of the other end of the bridge plate 5. The rectangular grooves 503 of two adjacent bridge plates 5 match the rectangular blocks 504.
[0064] A horizontal circular groove is provided on the two side walls of the rectangular groove 503. A spring 15 is provided in the circular groove. One end of the spring 15 is fixedly connected to the bottom of the circular groove, and the other end is fixedly provided with a snap-fit block 16. The snap-fit block 16 is provided with an inclined surface that slopes from the outside to the inside.
[0065] The rectangular block 504 has snap-fit grooves 17 on both sides, and the snap-fit grooves 17 slide and match the snap-fit block 16.
[0066] Two through holes 502, one horizontal and one vertical, are provided on the two side walls of one end of the bridge plate 5. The through holes 502 are used to fix and connect the ropes.
[0067] When using this invention, the fixed platform 1 is placed close to the water surface. The fixed base plate 102 of the fixed platform 1 can be fixed to the ground with bolts first. Then, according to actual needs, several counterweight plates 103 are placed on the upper surface of the fixed base plate 102 to ensure the stability of the entire device.
[0068] Then, several bridge plates 5 are placed in the through slot of the bridge plate temporary storage rack 2. In the initial state, the primary support plate 2011 and the secondary support plate 2012 of the supporting mechanism are both in the extended state, that is, the electric push rod 204 in the primary slot 202 is extended, and the electric push rod 205 in the secondary slot 203 is extended.
[0069] Several bridge plates 5 are stacked on the first-stage support plate 2011, and the protrusions 2013 of the first-stage support plate 2011 correspond to the grooves 501 at the bottom of the bridge plate 5;
[0070] Then, the electric push rod 204 retracts, bringing the first-stage support plate 2011 back into the first-stage groove 202. The bottommost bridge plate 5 falls from the first-stage support plate 2011 to the top of the second-stage support plate 2012. The protrusion 2013 of the second-stage support plate 2012 corresponds to the groove 501 at the bottom of the bridge plate 5. At this time, the electric push rod 204 extends, and the bridge plate 5 above the bottommost bridge plate 5 is again located on the first-stage support plate 2011.
[0071] At this time, electric push rod 1 7, electric push rod 2 11, and electric push rod 3 12 are all in the retracted state. Then, electric push rod 5 205 retracts, bringing the secondary support plate 2012 back into the corresponding secondary groove 203. The bottommost bridge plate 5 falls from the secondary support plate 2012 into the lower conveyor track 4.
[0072] Then, electric push rod 17 extends, driving connecting plate 10 to one end of bridge plate 5. Then electric push rod 312 extends, driving push plate 8 to move down until push plate 8 contacts the side of bridge plate 5. After that, electric push rod 17 retracts, and push plate 8 pushes bridge plate 5 to move away from fixed platform 1. When it moves to a position that does not affect the falling of bridge plate 5 above, push plate 8 stops moving and resets. Electric push rod 21 extends, driving pressure plate 9 to press bridge plate 5 down.
[0073] This process is repeated. When the second bridge plate 5 slides close to the first bridge plate, the push plate 8 continues to push the bridge plate 5. As the rectangular block 504 of the second bridge plate 5 slowly moves forward, it presses against the inclined surface of the locking block 16 and pushes it into the circular groove of the rectangular groove 503. When the locking groove 17 aligns with the rectangular groove 503, due to the elastic force of the spring 15, the locking block 16 will enter the locking groove 17, thereby completing the fixation between the two bridge plates 5.
[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
