Description

Technical Field

[0001] The present invention relates to the technical field of power monitoring for energy storage power stations, and in particular to a power monitoring system for energy storage power stations. Background Art

[0002] With the acceleration of global energy transformation, the importance of energy storage technology in power systems is becoming increasingly prominent. Energy storage power stations, as facilities that can store and release electrical energy, are widely used in various fields, including grid peak and frequency regulation, renewable energy consumption, and distributed energy management. However, energy storage power stations operate in a complex environment, involve numerous devices, and involve electrical parameters such as high voltage and high current. Their safety and stability have always been a focus of industry attention. The safe and normal operation of energy storage power stations requires the cooperation of power monitoring devices. Power monitoring devices can measure power parameters and monitor and analyze power quality, providing excellent protection for the operation of energy storage power stations.

[0003] The existing Chinese patent with publication number CN118973172B includes a power monitoring device body and a support carrier plate on which the power monitoring device body is installed. A bent fixing plate is fixedly provided at the upper end of the power monitoring device body, and a movable channel is provided on the bent fixing plate. Stable sockets are respectively provided on one end of the bent fixing plate close to the movable channel and the other end away from the movable channel, and a connection socket is provided on the power monitoring device body on the lower side of the bent fixing plate.

[0004] When the above device is in use, it is positioned on the supporting carrier plate through the supporting positioning column, and then the supporting movable frame is pushed to drive the movable sleeve plate to move, so that the connecting strip plate is inserted into the limit groove, thereby realizing the first layer of fixation of the power monitoring device body. At the same time, under the action of the connecting strip plate, the movable limit rod will be driven to move, so that the movable limit rod is inserted into the limit socket to realize its second layer of fixation, fully ensuring the firmness of the installation of the power monitoring device body, and the operation is simple, convenient and fast. However, in actual use, since the power monitoring device is exposed to the outside world for a long time and dust in the outside air settles on its surface, it is easy to cause blockage of the heat dissipation holes of the power monitoring device, affecting its heat dissipation effect, and the use effect is poor, so the protective sealing of the power monitoring device is poor.

[0005] To this end, we proposed a power monitoring system for energy storage power stations. Summary of the Invention

[0009] Preferably, support rods supporting the L-shaped sealing plate are rotatably connected to symmetrical positions at both ends of the fixed plate, and the support rods at both ends are rotatably supported at symmetrical positions on an adjacent side of the power monitoring device body at one end away from the fixed plate.

[0010] Preferably, support grooves are provided at symmetrical positions on both sides of the bottom of the protective shell, and the inner walls of the support grooves on both sides are movably connected with L-shaped rods that can move back and forth horizontally. The opposite ends of the L-shaped rods on both sides are fixedly connected with fixed clamps for clamping and fixing the power monitoring device body, and the L-shaped plates are provided with auxiliary mechanisms for pulling the L-shaped rods on both sides to move toward or away from each other and to clamp and release the power monitoring device body.

[0011] Preferably, the auxiliary mechanism includes an L-shaped plate with a movable groove, the inner wall of the movable groove is movably connected to a second T-shaped block that can move back and forth horizontally, and the symmetrical positions at both ends of the second T-shaped block are both fixedly axially connected to adjustment rods that pull the L-shaped rod to move back and forth toward or away from each other, and second connecting seats are fixedly connected to the opposite surfaces of the L-shaped rods on both sides, and each of the adjusting rods is rotatably connected to the second connecting seat on the adjacent side at one end away from the second T-shaped block through a pin shaft.

[0012] Preferably, a movable groove for supporting the first T-shaped block is provided on the second T-shaped block, and the bottom end of the first T-shaped block passes through the inner wall of the movable groove and is movably connected, and a first spring is fixedly connected to the surface of the movable groove opposite to the first T-shaped block near one end of the fixed plate to guide the second T-shaped block to perform reset movement.

[0013] Preferably, a monitoring mechanism for monitoring the temperature of the power monitoring device body is provided on the fixed splint, and the monitoring mechanism includes cylindrical shells that are penetrated and fixedly connected at symmetrical positions on one end of the fixed splints on both sides, and the inner wall of each of the cylindrical shells is movably connected to a piston plate that moves horizontally back and forth, and the inner walls of the opposite ends of the cylindrical shells on both sides are provided with alcohol that is easily expanded by heat and pushes the piston plate to move horizontally.

[0014] Preferably, the inner walls of the two opposite ends of the cylindrical shells are fixedly connected with pressure sensors for monitoring the temperature on both sides of the power monitoring device body, and the pressure sensors are connected to the external control system through signals. The pressure sensor on each side and the opposite surface of the piston plate on the adjacent side are fixedly connected with a second spring for applying pressure to the pressure sensor.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By driving the threaded rod to rotate back and forth through the motor, the threaded rod can drive the first T-shaped block to move back and forth horizontally, and then drive the L-shaped sealing plate to flip back and forth, which can quickly complete the sealing and opening operations of the operation window, so that the L-shaped sealing plate can fit tightly against the operation window to form a good sealing environment, effectively preventing external dust, moisture and electromagnetic interference from entering the protective shell, and avoiding the problem of dust and moisture intrusion causing blockage of the heat dissipation holes of the power monitoring device body and circuit short circuit. At the same time, there is no need for manual disassembly or installation of protective devices, which saves operation time and improves work efficiency, so that the staff can perform daily maintenance and operation of the power monitoring device body.

[0016] 2. Through the linkage of the second T-shaped block, the adjustment rod and the L-shaped rod, the fixed clamps can be driven to move toward each other, clamping and fixing the power monitoring device body, effectively preventing the power monitoring device body from being displaced or damaged due to collision in the protective shell, ensuring its stability during operation, and ensuring the accuracy and reliability of the monitoring data. When the power monitoring device body needs to be operated and maintained, as the first T-shaped block is reset and moved horizontally toward the end close to the fixed plate, the fixed clamps move away from each other and release the clamping of the power monitoring device body. No complicated tools or tedious steps are required, so that staff can install, disassemble and maintain the power monitoring device body, thereby improving the maintainability of the equipment.

[0017] 3. The cylindrical shell is made of aluminum alloy with high thermal conductivity, which can quickly conduct the heat of the power monitoring device body to the inside and contact with alcohol. The thermal expansion principle of alcohol is used to push the piston plate to move, and the pressure applied by the second spring to the pressure sensor gradually increases. The pressure sensor is connected to the external controller through a signal, and then the pressure sensor can convert the monitored pressure value into an electrical signal and remotely transmit it to the external controller, so that the staff can remotely monitor the temperature of the protective shell in real time. When the pressure value monitored by the pressure sensor reaches the set threshold, the external control system will promptly issue an alarm to remind the staff to take corresponding measures, such as heat dissipation or shutdown inspection, etc., which can effectively prevent the occurrence of equipment overheating failures and ensure the safe and stable operation of the power monitoring system.

[0018] The coordinated use of the above-mentioned structure solves the problem that, in actual use of the existing device, the power monitoring device is exposed to the outside world for a long time, and dust in the outside air settles on its surface, which easily blocks the heat dissipation holes of the power monitoring device, affecting its heat dissipation effect and resulting in poor use effect, thereby solving the problem of poor protective sealing of the power monitoring device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figures 1 to 8 The present invention provides a technical solution: a power monitoring system for an energy storage power station, comprising a power monitoring device body 8 for monitoring the energy storage power station and a protective shell 1 for protecting the power monitoring device body 8, wherein the protective shell 1 is provided with an operation window 101 for personnel to operate the internal power monitoring device body 8, an L-shaped plate 2 is fixedly connected to the bottom of the operation window 101, and a fixed plate 3 is fixedly connected to the end of the L-shaped plate 2 away from the operation window 101, and cylindrical rods 4 are fixedly connected to the opposite surfaces of the L-shaped plate 2 at both ends of the fixed plate 3, and first T-shaped blocks 5 for horizontal reciprocating movement are sleeved on the outer contours of the two cylindrical rods 4, and first connecting seats 6 are fixedly connected at symmetrical positions at both ends of the first T-shaped block 5, and L-shaped sealing plates 7 for sealing the operation window 101 are fixedly connected to the first connecting seats 6 at both ends, and the power monitoring device body 8 is supported and placed on the L-shaped sealing plates 7, and the fixed plate 3 is provided with a flipping mechanism for driving the L-shaped sealing plate 7 to flip back and forth and seal and open the operation window 101.

[0024] When in use, by setting the power monitoring device body 8 and the protective shell 1, the protective shell 1 can protect the power monitoring device body 8 on the inner wall, thereby improving the safety of the power monitoring device body 8. Through the operation window 101 opened on the protective shell 1, the staff can operate or maintain the internal power monitoring device body 8 through the operation window 101. The L-shaped plate 2 set on the operation window 101 is fixedly supported on the protective shell 1. The fixing plate 3 set on the L-shaped plate 2 can fix the fixing plate 3 on the L-shaped plate 2 and fix it. The cylindrical rod 4 arranged on the plate 3 enables the cylindrical rod 4 to be fixedly supported at symmetrical positions on both sides of the L-shaped plate 2 and the fixed plate 3. Through the first T-shaped block 5 arranged on the cylindrical rod 4, and the cylindrical rod 4 supports the first T-shaped block 5, the first T-shaped block 5 can be horizontally reciprocated and connected on the outer contour of the cylindrical rod 4. Through the first connecting seat 6 set on the first T-shaped block 5, the first connecting seat 6 is fixedly supported at symmetrical positions at both ends of the first T-shaped block 5, and the L-shaped sealing plate 7 set on the first connecting seat 6 can enable the L-shaped sealing plate 7 to be rotatably supported on the first connecting seat 6.

[0025] like Figure 1 and Figure 2 As shown, first, the power monitoring device body 8 is supported and placed on the inner wall of the L-shaped sealing plate 7, and the flip mechanism is set on the fixed plate 3, so that the flip mechanism can drive the L-shaped sealing plate 7 to flip back and forth, and then the flip of the L-shaped sealing plate 7 can seal and open the operation window 101, thereby realizing the sealed storage of the power monitoring device body 8 inside the protective shell 1, and at the same time, the seal of the operation window 101 can be released, so that the staff can operate and maintain the power monitoring device body 8 inside the protective shell 1.

[0026] Example 2:

[0027] On the basis of the first embodiment, further steps are as follows: The flipping mechanism includes a threaded rod 9 that is penetrated and fixedly connected on the fixed plate 3 and is driven to rotate by the power mechanism. The first T-shaped block 5 is penetrated and fixedly connected at a position corresponding to the threaded rod 9, and a threaded sleeve 10 that drives the first T-shaped block 5 to move horizontally reciprocating is penetrated and fixedly connected, and the inner wall of the threaded sleeve 10 is penetrated by the threaded rod 9 and is screwed.

[0028] The support rods 11 supporting the L-shaped sealing plate 7 are rotatably connected to the symmetrical positions at both ends of the fixed plate 3. The support rods 11 at both ends are rotatably supported at symmetrical positions on the adjacent side of the power monitoring device body 8 at one end away from the fixed plate 3.

[0029] During use, through the threaded rod 9 provided on the fixed plate 3, and the threaded rod 9 is driven to rotate by the motor after being energized, the motor can drive the threaded rod 9 to perform fixed-axis reciprocating rotation on the fixed plate 3, and the threaded sleeve 10 provided on the first T-shaped block 5 fixes the threaded sleeve 10 on the threaded rod 9, and the threaded sleeve 10 is screwed to the threaded rod 9. As the threaded rod 9 performs fixed-axis reciprocating rotation, the threaded sleeve 10 can drive the first T-shaped block 5 to perform horizontal reciprocating motion along the cylindrical rod 4 under the action of the threaded rod 9.

[0030] like Figure 2 、 Figure 4 and Figure 5 As shown, by the support rod 11 provided on the fixed plate 3, the two ends of the support rod 11 can be respectively supported on the fixed plate 3 and the L-shaped sealing plate 7 by fixed axis rotation, and the threaded rod 9 drives the first T-shaped block 5 to move horizontally toward the end away from the fixed plate 3, and the L-shaped sealing plate 7 is rotatably supported on the first connecting seat 6, so that the support rod 11 can pull the L-shaped sealing plate 7 to rotate in the B direction. When the first T-shaped block 5 moves to the extreme position away from one end of the fixed plate 3, the L-shaped sealing plate 7 rotates ninety degrees in the B direction, and the L-shaped sealing plate 7 is sealed with the operation window 101, effectively preventing external dust, moisture and electromagnetic interference from entering the protective shell 1, avoiding the intrusion of dust and moisture causing the heat dissipation holes of the power monitoring device body 8 to be blocked, causing the circuit short circuit problem, improving the protection performance of the power monitoring device body 8, avoiding equipment failures caused by environmental factors, and extending the service life of the equipment.

[0031] As the threaded rod 9 drives the first T-shaped block 5 to perform a horizontal reset movement toward one end close to the fixed plate 3, the above-mentioned structure can simultaneously reset and move in the opposite direction, and the L-shaped sealing plate 7 can be reset and rotated ninety degrees in the opposite direction of B, and then the L-shaped sealing plate 7 releases the sealing state of the operation window 101, so that the staff can operate or maintain the internal power monitoring device body 8 through the operation window 101. Through the coordinated use of the above-mentioned structure, the automatic flipping of the L-shaped sealing plate 7 is realized, and there is no need for manual disassembly or installation of protective devices, which not only saves operation time, but also reduces the complexity and error rate of manual operation.

[0032] Example 3:

[0033] On the basis of the second embodiment, further steps are as follows: Support grooves 102 are provided at symmetrical positions on both sides of the bottom of the protective shell 1. The inner walls of the support grooves 102 on both sides are movably connected with L-shaped rods 12 that can move horizontally back and forth. The opposite ends of the L-shaped rods 12 on both sides are fixedly connected with fixed clamps 13 for clamping and fixing the power monitoring device body 8. The L-shaped plate 2 is provided with an auxiliary mechanism for pulling the L-shaped rods 12 on both sides to move toward or away from each other and to clamp and release the power monitoring device body 8.

[0034] During use, through the operation window 101 opened on the protective shell 1 and the L-shaped rod 12 set on the support groove 102, the support groove 102 can support the L-shaped rod 12, so that the L-shaped rod 12 can be moved horizontally and connected to the inner wall of the support groove 102, and the fixed splint 13 set on the L-shaped rod 12 is fixedly supported on the L-shaped rod 12, and the auxiliary mechanism set on the L-shaped plate 2 can pull the fixed splints 13 on both sides to move back and forth toward or away from each other, thereby fixing or releasing the power monitoring device body 8 on the L-shaped sealing plate 7, and improving the stability of the power monitoring device body 8.

[0035] Example 4:

[0036] On the basis of the third embodiment, further steps are as follows: The auxiliary mechanism includes an L-shaped plate 2 with a movable groove 201, and the inner wall of the movable groove 201 is movably connected to a second T-shaped block 14 that performs horizontal reciprocating movement. The second T-shaped block 14 is symmetrically positioned at both ends and is rotatably connected to an adjusting rod 15 that pulls the L-shaped rod 12 to perform reciprocating movement toward or away from each other. Second connecting seats 21 are fixedly connected to the opposite surfaces of the L-shaped rods 12 on both sides, and each of the adjusting rods 15 is rotatably connected to the second connecting seat 21 on the adjacent side at one end away from the second T-shaped block 14 through a pin.

[0037] The second T-shaped block 14 is provided with a movable groove 141 for supporting the first T-shaped block 5, and the bottom end of the first T-shaped block 5 passes through the inner wall of the movable groove 141 and is movably connected. The movable groove 141 is close to the end of the fixed plate 3 and is fixedly connected to the surface opposite to the first T-shaped block 5 with a first spring 16 that guides the second T-shaped block 14 to perform reset movement.

[0038] During use, through the movable groove 201 provided on the L-shaped plate 2 and the second T-shaped block 14 provided on the movable groove 201, the movable groove 201 supports the second T-shaped block 14, so that the second T-shaped block 14 can be horizontally moved and connected on the inner wall of the movable groove 201. Through the adjusting rod 15 provided on the second T-shaped block 14 and the second connecting seat 21 provided on the L-shaped rod 12, the two ends of the adjusting rod 15 can be respectively axially rotatably supported on the second T-shaped block 14 and the second connecting seat 21. Through the movable groove 141 provided on the second T-shaped block 14, the bottom end of the first T-shaped block 5 can be horizontally moved and connected on the inner wall of the movable groove 141. Through the first spring 16 provided on the movable groove 141, the two ends of the first spring 16 are fixedly supported on the movable groove 141 and the first T-shaped block 5.

[0039] like Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, in the initial state, the first T-shaped block 5 is located at the extreme position at one end of the fixed plate 3, and the first spring 16 is in an extruded and contracted state under the action of the first T-shaped block 5. As the first T-shaped block 5 moves horizontally in the direction away from the fixed plate 3, the first T-shaped block 5 moves synchronously along the inner wall of the movable groove 141 toward the end away from the first spring 16. At this time, the first spring 16 is released, and the first spring 16 supports the position of the second T-shaped block 14, so that the second T-shaped block 14 is in conflict with the fixed plate 3 under the elastic force of the first spring 16 and remains in a stationary state. As the first T-shaped block 5 moves to the movable groove 141 away from the fixed plate 3 When one end of the first spring 16 reaches the extreme position, the first T-shaped block 5 can pull the second T-shaped block 14 to move horizontally synchronously toward the end away from the fixed plate 3, and the adjusting rod 15 can pull the L-shaped rods 12 on both sides to move horizontally toward each other under the action of the second T-shaped block 14, and then the L-shaped rods 12 can drive the fixed clamping plates 13 to move toward each other and clamp on both sides of the power monitoring device body 8, ensuring the stability of the power monitoring device body 8 on the L-shaped sealing plate 7, avoiding the protective shell 1 from accidentally colliding with the outside world, causing the power monitoring device body 8 to slide and collide with the inner wall of the protective shell 1, resulting in damage to the power monitoring device body 8.

[0040] When the first T-shaped block 5 is reset and moved horizontally toward one end close to the fixed plate 3, the second T-shaped block 14 can move synchronously with the first T-shaped block 5 under the elastic force of the first spring 16, and the adjusting rod 15 can push the L-shaped rods 12 on both sides to reset and move in opposite directions, so that the L-shaped rods 12 can drive the fixed clamping plates 13 to move oppositely to release the clamping state of the power monitoring device body 8, so that the staff can install, disassemble and maintain the power monitoring device body 8, thereby improving the maintainability of the equipment and avoiding obstruction to the flipping of the power monitoring device body 8. When the second T-shaped block 14 moves and conflicts with the fixed plate 3, the first T-shaped block 5 can be moved horizontally toward one end close to the first spring 16, and the first spring 16 is pressurized and contracted, thereby improving the stability of the second T-shaped block 14.

[0041] Embodiment 5:

[0042] On the basis of the fourth embodiment, further steps are as follows: The fixed splint 13 is provided with a monitoring mechanism for monitoring the temperature of the power monitoring device body 8. The monitoring mechanism includes cylindrical shells 17 that are penetrated and fixedly connected at symmetrical positions on one end of the fixed splints 13 on both sides. The inner wall of each cylindrical shell 17 is movably connected to a piston plate 18 that moves horizontally back and forth. The inner walls of the opposite ends of the cylindrical shells 17 on both sides are provided with alcohol that is easily expanded by heat and pushes the piston plate 18 to move horizontally.

[0043] The inner walls of the two opposite ends of the cylindrical shells 17 are fixedly connected with pressure sensors 19 for monitoring the temperature on both sides of the power monitoring device body 8, and the pressure sensor 19 is connected to the external control system through signals. The pressure sensor 19 on each side and the opposite surface of the piston plate 18 on the adjacent side are fixedly connected with a second spring 20 for applying pressure to the pressure sensor 19.

[0044] During use, the cylindrical shell 17 is fixedly supported on the fixed splint 13 by the cylindrical shell 17 provided on the fixed splint 13, and the piston plate 18 provided on the cylindrical shell 17 enables the piston plate 18 to be moved horizontally and connected to the inner wall of the cylindrical shell 17, and the fixed splint 13 moves toward each other and is clamped on both sides of the power monitoring device body 8, so that the opposite ends of the cylindrical shell 17 can contact the two sides of the power monitoring device body 8, and the cylindrical shell 17 is made of aluminum alloy material with high thermal conductivity, so the cylindrical shell 17 can conduct the heat from the surface of the power monitoring device body 8, and the interior of the cylindrical shell 17 near one end of the power monitoring device body 8 is provided with alcohol that is easily expanded by heat, and the cylindrical shell 17 conducts the heat of the power monitoring device body 8 to the interior and contacts with the alcohol, so that the thermal expansion characteristics of the alcohol can be used to push the piston plate 18 toward the side close to the pressure sensor 19. The end moves, and the second spring 20 is squeezed and contracted under the push of the piston plate 18, which can gradually increase the pressure applied by the second spring 20 to the pressure sensor 19, and the pressure sensor 19 is connected to the external controller through a signal, and then the pressure sensor 19 can convert the monitored pressure value into an electrical signal and remotely transmit it to the external controller, so that the staff can remotely monitor the temperature of the protective shell 1 in real time. When the pressure monitored by the pressure sensor 19 reaches the set threshold, the external controller can issue an alarm to the staff, reminding the staff to take corresponding measures, such as heat dissipation treatment or shutdown inspection, etc., which can effectively prevent the occurrence of equipment overheating failure and ensure the safe and stable operation of the power monitoring system. The above-mentioned pressure sensor 19 can convert the monitored pressure value into an electrical signal and remotely transmit it to the external controller, which is a prior art content well known to people in this field, so it will not be repeated here.

[0045] Furthermore, it is achieved that the existing device can seal and protect the power monitoring device during actual use, is easy to use, and is better than traditional products.

[0046] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
