Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and particularly to an axial vibration acquisition device for a water energy storage unit. Background Art

[0002] A pumped-storage power station is a hydropower station that pumps water during the low-power period of the power system and generates electricity during the peak load period. The pumped-storage power station is equipped with upper and lower reservoirs. It uses the surplus power during the low-power period of the power system to pump the water in the lower reservoir into the upper reservoir to store energy; during the peak load period of the power system, the water is released from the upper reservoir to generate electricity.

[0003] There is a prior Chinese patent publication number: CN112857799B, an axial vibration acquisition device for a pumped-storage unit, including an annular base arranged on the ground. The base is sleeved on the lower end of the rotor main shaft and is coaxially arranged with the rotor main shaft. A plurality of sets of marking devices are symmetrically arranged along the radial direction on the outer side wall of the lower end of the rotor main shaft. The marking device includes a support rod and a flexible ball. One end of the support rod is fixedly connected to the side wall of the rotor main shaft, and the flexible ball is embedded in the other end of the support rod and is rotatably connected to the support rod; a ink-dropping device is arranged on the side wall of the rotor main shaft on one side of the flexible ball; a contact plate is detachably connected to the inner side wall of the base. When the rotor main shaft does not rotate, the flexible ball is in point contact with the contact plate.

[0004] Although the above solution has the effect of facilitating the acquisition of the amplitude of the axial vibration of the unit, the acquisition device is installed on the surface of the rotating shaft. When the rotating shaft rotates, it often generates large vibrations. There are many sensors and electronic devices inside the acquisition device. After a long time of vibration, the electronic components inside the collector may be damaged due to the long vibration time, so it is necessary to reduce the vibration of the collector and improve the service life of the collector during use. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the electronic components inside the collector may be damaged due to the long vibration time after a long time of vibration.

[0006] To achieve the above object, the present invention adopts the following technical solution: a shaft system vibration acquisition device for a water energy storage unit, comprising: a support plate and a mounting plate. A plurality of dampers are fixedly connected to the top of the outer surface of the mounting plate, and a plurality of first springs are fixedly connected to the top of the outer surface of the mounting plate. The top of the outer surface of the plurality of first springs is fixedly connected to a mounting box. Two first limit rods are fixedly connected to the outer surface of the support plate. A moving plate is movably sleeved on the outer surfaces of the two first limit rods. A motor is fixedly connected to the outer surface of the moving plate. The output end of the motor is fixedly connected to a rotating rod. Two first bearings are movably sleeved on the outer surface of the rotating rod. Two fixed blocks are fixedly connected to the bottom of the outer surface of the mounting plate. Threaded rods are movably embedded in the interiors of the two fixed blocks. Second limit rods are movably embedded in the interiors of the two fixed blocks. One end of each of the two threaded rods is rotatably connected to a moving semi-circular block through a bearing. The two second limit rods are fixedly connected to the outer surfaces of the two moving semi-circular blocks. Two fixed semi-circular blocks are fixedly connected to the bottom of the outer surface of the mounting plate. The two moving semi-circular blocks and the two fixed semi-circular blocks are all located on the outer surface of the two first bearings. The output end of the motor is fixedly connected to a rotating rod.

[0007] The technical effect of adopting the above further solution is that by rotating the threaded rod and being limited by the second limit rod, the moving semi-circular block moves. At this time, the moving semi-circular block and the fixed semi-circular block can clamp and fix the surface of the first bearing. At this time, the mounting box is mounted on the outer surface of the rotating rod. When the rotating rod rotates, vibrations will be generated. Under the combined limitation of the damper and the first spring, the vibrations brought by the rotating rod can be offset, reducing the vibration of the mounting box, reducing the damage to the internal components of the mounting box, and improving the service life of the internal components of the mounting box.

[0008] As a preferred implementation manner, a plurality of L-shaped blocks are fixedly connected to the outer surface of the mounting box near the top thereof. Pull rods are movably embedded in the interiors of the plurality of L-shaped blocks. One end of each of the plurality of pull rods is fixedly connected to a limiting circular block. Second springs are fixedly connected to the outer surfaces of the plurality of limiting circular blocks. Clamping rods are fixedly connected to the outer surfaces of the plurality of limiting circular blocks. A plurality of grooves are formed in the top of the outer surface of the mounting box.

[0009] The technical effect of adopting the above further solution is that by pulling the pull rod to drive the limiting circular block to move to one side, at this time the second spring expands and contracts, and the clamping rod moves on the inner wall of the groove. At this time, pull the cover plate to disassemble it. During installation, under the limiting action of the second spring, the clamping rod is stuck in the circular hole on the outer surface of the convex block to install the cover plate.

[0010] As a preferred embodiment, bumpers are movably embedded inside multiple ones of the grooves. Round holes are formed on the outer surfaces of the multiple bumpers. The multiple clamping rods are movably embedded inside the multiple round holes. An eddy current displacement sensor is arranged inside the installation box. A displacement and rotational speed sensor is arranged inside the installation box. A data acquisition device is arranged inside the installation box. A data analysis device is arranged inside the installation box.

[0011] The technical effect of adopting the above further solution is: It is convenient to disassemble and install the cover plate, and it is convenient for the staff to repair the components inside the installation box.

[0012] As a preferred embodiment, a data transmission device is arranged inside the installation box. A storage battery is arranged inside the installation box. An electric push rod II is fixedly connected to the outer surface of the groove. A moving block is fixedly connected to the outer surface of the electric push rod II. Two convex rods are fixedly connected to the outer surface of the moving block. Two clamping holes are formed on the outer surface of the installation plate. The two convex rods are movably embedded inside the two clamping holes.

[0013] The technical effect of adopting the above further solution is: When the motor runs for a long time, the eddy current displacement sensor can sense the water flow velocity of the eddy current. When the rotating rod runs for a long time, displacement will occur. At this time, the displacement and rotational speed sensor can detect the displacement distance of the rotating rod. Through the installation box and the displacement and rotational speed sensor, the sensed data can be output to the inside of the data acquisition device, and then transmitted to the data analysis device through the data acquisition device for effective analysis. When the water flow inside the water pump is too large or the displacement distance of the rotating rod is slightly large, the information will be transmitted to the inside of the data transmission device. The data transmission device transmits the information to the staff, which is convenient for the staff to observe and analyze the operation data of the device.

[0014] As a preferred embodiment, a turbine is fixedly sleeved on the outer surface of the rotating rod. A water pump is sleeved on the outer surface of the rotating rod through a bearing. The turbine is located inside the water pump. A water suction pipe is fixedly connected to the bottom of the outer surface of the water pump. A water delivery pipe is fixedly connected to the outer surface of the water pump. The water pump is fixedly connected to the outer surface of the moving plate. An electric push rod I is fixedly connected to the outer surface of the support plate. One end of the electric push rod I is fixedly connected to the outer surface of the moving plate. A cover plate is fixedly connected to the top of the outer surfaces of the multiple bumpers.

[0015] The technical effect of adopting the above further solution is: By starting the electric push rod I with an external power source to push the moving plate to slide on the outer surface of the limiting rod I, the height of the entire device can be adjusted at this time. When the water level is low, the height of the water suction pipe can be lowered even further to pump water from a lower water level, improving the working efficiency.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0017] 1. In the embodiment of the present invention, by rotating the threaded rod, the moving semi-circular block moves under the limitation of the second limiting rod. At this time, the moving semi-circular block and the fixed semi-circular block can clamp and fix the surface of the first bearing. At this time, the installation box is installed on the outer surface of the rotating rod. When the rotating rod rotates, vibration will be generated. Under the cooperation and limitation of the damper and the first spring, the vibration brought by the rotating rod can be offset, reducing the vibration of the installation box, reducing the damage to the internal components of the installation box, and improving the service life of the internal components of the installation box.

[0018] 2. In the embodiment of the present invention, the support plate is installed on the surface of the water energy storage unit, and then the motor is started by an external power source. The motor drives the rotating rod to rotate, and the rotating rod drives the turbine to rotate. At this time, water is pumped into the internal of the water pump through the water suction pipe, and then output to the internal of the upstream reservoir through the water delivery pipe for power generation. It should be noted that the lengths of the water suction pipe and the water delivery pipe can be determined according to the actual use situation. After the motor runs for a long time, the eddy current displacement sensor can sense the water flow velocity of the eddy current. After the rotating rod runs for a long time, displacement will occur. At this time, the displacement rotation speed sensor can detect the displacement distance of the rotating rod. Through the installation box and the displacement rotation speed sensor, the sensed data can be output to the internal of the data acquisition device, and then transmitted to the data analysis device through the data acquisition device for effective analysis. When the water flow inside the water pump is too large or the displacement distance of the rotating rod is slightly large, the information will be transmitted to the internal of the data transmission device, and the data transmission device will transmit the information to the staff, which is convenient for the staff to observe and analyze the operation data of the device.

[0019] 3. In the embodiment of the present invention, the height of the entire device can be adjusted. When the water level is low, the height of the water suction pipe can be lowered even further. The electric push rod two is started by an external power source to push the moving block to move. At this time, the convex rod on the moving block is embedded into the internal of the two card holes to fix the installation plate, preventing the installation plate from rotating with the rotation of the two first bearings. When it is necessary to disassemble and repair the internal of the installation box, by pulling the pull rod to drive the limiting circular block to move to one side, at this time the second spring expands and contracts, and the clamping rod moves on the inner wall of the groove. At this time, pull the cover plate to disassemble it. During installation, under the limiting action of the second spring, the clamping rod is stuck in the circular hole on the outer surface of the convex block to install the cover plate.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 8 Figures 1 to 8 , this embodiment provides a technical solution: a shafting vibration acquisition device for a water energy storage unit, including: a support plate 101 and a mounting plate 109. A plurality of dampers 119 are fixedly connected to the top of the outer surface of the mounting plate 109. A plurality of first springs 118 are fixedly connected to the top of the outer surface of the mounting plate 109. A mounting box 120 is fixedly connected to the top of the outer surfaces of the plurality of first springs 118. Two first limiting rods 102 are fixedly connected to the outer surface of the support plate 101. A moving plate 103 is movably sleeved on the outer surfaces of the two first limiting rods 102. A motor 105 is fixedly connected to the outer surface of the moving plate 103. A rotating rod 116 is fixedly connected to the output end of the motor 105. Two first bearings 117 are movably sleeved on the outer surface of the rotating rod 116. Two fixing blocks 111 are fixedly connected to the bottom of the outer surface of the mounting plate 109. A threaded rod 112 is movably embedded in each of the two fixing blocks 111. A second limiting rod 113 is movably embedded in each of the two fixing blocks 111. One end of each of the two threaded rods 112 is rotatably connected to a moving semi-circular block 114 through a bearing. The two second limiting rods 113 are fixedly connected to the outer surfaces of the two moving semi-circular blocks 114. Two fixed semi-circular blocks 115 are fixedly connected to the bottom of the outer surface of the mounting plate 109. The two moving semi-circular blocks 114 and the two fixed semi-circular blocks 115 are both located on the outer surface of the two first bearings 117. The output end of the motor 105 is fixedly connected to the rotating rod 116.

[0032] During use, by rotating the threaded rod 112 under the limitation of the second limiting rod 113, the moving semi-circular block 114 moves. At this time, the moving semi-circular block 114 and the fixed semi-circular block 115 can clamp and fix the surface of the first bearing 117. At this time, the mounting box 120 is mounted on the outer surface of the rotating rod 116. When the rotating rod 116 rotates, vibrations will be generated. Under the combined limitation of the damper 119 and the first spring 118, the vibrations brought by the rotating rod 116 can be offset, reducing the vibration of the mounting box 120, reducing the damage to the internal components of the mounting box 120, and improving the service life of the internal components of the mounting box 120.

[0033] Such as Figures 1 to 8As shown, a plurality of L-shaped blocks 127 are fixedly connected to the outer surface of the installation box 120 near the top of its outer surface. A pull rod 129 is movably embedded in each of the plurality of L-shaped blocks 127. One end of each of the plurality of pull rods 129 is fixedly connected with a limiting circular block 130. A second spring 128 is fixedly connected to the outer surface of each of the plurality of limiting circular blocks 130. A clamping rod 133 is fixedly connected to the outer surface of each of the plurality of limiting circular blocks 130. A plurality of grooves 131 are formed in the top of the outer surface of the installation box 120. By pulling the pull rod 129 to drive the limiting circular block 130 to move to one side, at this time the second spring 128 expands and contracts, and the clamping rod 133 moves on the inner wall of the groove 131. At this time, pull the cover plate 132 to disassemble it. When installing, under the limiting action of the second spring 128, the clamping rod 133 is stuck in the circular hole 135 on the outer surface of the convex block 134 to install the cover plate 132.

[0034] As Figures 1 to 8 shown, a convex block 134 is movably embedded in each of the plurality of grooves 131. A circular hole 135 is formed in the outer surface of each of the plurality of convex blocks 134. Each of the plurality of clamping rods 133 is movably embedded in each of the plurality of circular holes 135. An eddy current displacement sensor 121 is arranged inside the installation box 120. A displacement and rotational speed sensor 122 is arranged inside the installation box 120. A data acquisition device 123 is arranged inside the installation box 120. A data analysis device 124 is arranged inside the installation box 120, which is convenient for disassembling and installing the cover plate 132 and convenient for the staff to repair the internal components of the installation box 120.

[0035] As Figures 1 to 8 shown, a data transmission device 125 is arranged inside the installation box 120. A storage battery 126 is arranged inside the installation box 120. An electric push rod two 106 is fixedly connected to the outer surface of the groove 131. A moving block 107 is fixedly connected to the outer surface of the electric push rod two 106. Two convex rods 108 are fixedly connected to the outer surface of the moving block 107. Two clamping holes 110 are formed in the outer surface of the installation plate 109. Each of the two convex rods 108 is movably embedded in each of the two clamping holes 110. When the motor 105 runs for a long time, the eddy current displacement sensor 121 can sense the water flow velocity of the eddy current. When the rotating rod 116 runs for a long time, displacement will occur. At this time, the displacement and rotational speed sensor 122 can detect the displacement distance of the rotating rod 116. The sensed data can be output to the inside of the data acquisition device 123 through the installation box 120 and the displacement and rotational speed sensor 122, and then transmitted to the data analysis device 124 through the data acquisition device 123 for effective analysis. When the water flow inside the water pump 136 is too large or the offset distance of the rotating rod 116 is slightly large, the information will be transmitted to the inside of the data transmission device 125. The data transmission device 125 transmits the information to the staff, which is convenient for the staff to observe and analyze the operation data of the device.

[0036] As Figures 1 to 8 shown, a turbine 137 is fixedly sleeved on the outer surface of the rotating rod 116. A water pump 136 is sleeved on the outer surface of the rotating rod 116 through a bearing. The turbine 137 is located inside the water pump 136. A water suction pipe 138 is fixedly connected to the bottom of the outer surface of the water pump 136. A water delivery pipe 139 is fixedly connected to the outer surface of the water pump 136. The water pump 136 is fixedly connected to the outer surface of the moving plate 103. An electric push rod 104 is fixedly connected to the outer surface of the support plate 101. One end of the electric push rod 104 is fixedly connected to the outer surface of the moving plate 103. A cover plate 132 is fixedly connected to the top of the outer surface of a plurality of bumps 134. By starting the electric push rod 104 through an external power source to push the moving plate 103 to slide on the outer surface of the limiting rod 102, the height of the entire device can be adjusted at this time. When the water level is relatively low, the height of the water suction pipe 138 can be lowered even lower to pump water from the lower water level, improving the working efficiency.

[0037] Working principle: When in use, the support plate 101 is installed on the surface of the water energy storage unit, and then the motor 105 is started by an external power source. The motor 105 drives the rotating rod 116 to rotate, and the rotating rod 116 drives the turbine 137 to rotate. At this time, water is pumped into the inside of the water pump 136 through the water suction pipe 138, and then output to the inside of the upstream reservoir through the water delivery pipe 139 for power generation. It should be noted that the lengths of the water suction pipe 138 and the water delivery pipe 139 can be determined according to the actual use situation. When the motor 105 operates for a long time, the eddy current displacement sensor 121 can sense the water flow velocity of the eddy current. When the rotating rod 116 operates for a long time, displacement will occur. At this time, the displacement speed sensor 122 can detect the displacement distance of the rotating rod 116. The induction data can be output to the inside of the data acquisition device 123 through the installation box 120 and the displacement speed sensor 122, and then transmitted to the data analysis device 124 through the data acquisition device 123 for effective analysis. When the water flow inside the water pump 136 is too large or the offset distance of the rotating rod 116 is slightly large, the information will be transmitted to the inside of the data transmission device 125. The data transmission device 125 transmits the information to the staff, which is convenient for the staff to observe and analyze the operation data of the device. By rotating the threaded rod 112 and being limited by the limiting rod two 113, the moving semi-circular block 114 moves. At this time, the moving semi-circular block 114 and the fixed semi-circular block 115 can clamp and fix the surface of the bearing one 117. At this time, the installation box 120 is installed on the outer surface of the rotating rod 116. When the rotating rod 116 rotates, vibration will be generated. Under the combined limitation of the damper 119 and the spring one 118, the vibration brought by the rotating rod 116 can be offset, reducing the vibration of the installation box 120, reducing the damage to the internal components of the installation box 120, and improving the service life of the internal components of the installation box 120. At the same time, the electric push rod one 104 is started by an external power source to push the moving plate 103 to slide on the outer surface of the limiting rod one 102. At this time, the height of the entire device can be adjusted. When the water level is low, the height of the water suction pipe 138 can be lowered even further. The electric push rod two 106 is started by an external power source to push the moving block 107 to move. At this time, the convex rod 108 on the moving block 107 is embedded into the two card holes 110 to fix the installation plate 109, preventing the installation plate 109 from rotating as the two bearings one 117 rotate. When it is necessary to disassemble and repair the inside of the installation box 120, by pulling the pull rod 129 to drive the limiting circular block 130 to move to one side, at this time the spring two 128 expands and contracts, and the clamping rod 133 moves on the inner wall of the groove 131. At this time, pull the cover plate 132 to disassemble it. When installing, under the limiting action of the spring two 128, the clamping rod 133 is stuck in the round hole 135 on the outer surface of the convex block 134 to install the cover plate 132.

Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present invention, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
