Description

Technical Field

[0001] This utility model relates to the field of power monitoring technology, specifically a power monitoring device for hydroelectric substations that is easy to install. Background Technology

[0002] The power monitoring equipment in a hydropower substation is a device used to monitor and control the operating status of the power system within the substation. It ensures the safe, stable, and efficient operation of power production. The power monitoring equipment in a hydropower substation typically includes data acquisition and monitoring systems, relay protection devices, video surveillance and environmental monitoring equipment, and power quality monitoring devices.

[0003] According to announcement number CN214535348U, an easy-to-install power monitoring device is disclosed, specifically relating to the field of power equipment technology. It includes a monitoring mounting base with a sliding groove at its bottom. A mounting frame is slidably connected to the inner wall of the sliding groove, and a camera device is fixedly installed at the bottom of the mounting frame. The monitoring mounting base has a rotating groove inside, with a rotating shaft rotatably connected to the inner wall of the rotating groove. A telescopic rod is slidably connected to the inner wall of the telescopic groove, and a knob is fixedly installed at one end of the rotating shaft on the front of the monitoring mounting base. A transmission mechanism is provided between the rotating shaft and the telescopic rod. This invention uses the rotation of the knob to move the telescopic rod within the telescopic groove, thereby engaging the telescopic rod with a slot, which fixes the mounting frame to which the camera device is fixed within the sliding groove. A return spring resets the telescopic rod, facilitating the connection between the telescopic rod and the slot. Therefore, the installation of the camera device in the power monitoring equipment is relatively convenient.

[0004] The above-mentioned device uses a return spring to reset the telescopic rod, which facilitates the connection between the telescopic rod and the slot. Therefore, the installation of the camera device in the power monitoring equipment is relatively convenient. According to the instruction manual and the attached drawings, the device fixes the camera device only by telescopic rod and slot on one side. Such unilateral fixation lacks symmetrical support. When the camera device rotates to the non-fixed side or is subjected to external impact, the device is prone to tipping over around the fixed point. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device uses a return spring to reset the telescopic rod, thereby facilitating the connection between the telescopic rod and the slot. Therefore, the installation of the camera device in the power monitoring equipment is more convenient. According to the specification and drawings, the device only fixes the camera device through the telescopic rod and the slot on one side. Such unilateral fixation lacks symmetrical support. When the camera device rotates to the non-fixed side or is subjected to external impact, the device is prone to tipping over around the fixed point. This utility model provides a power monitoring device for hydroelectric substations that is easy to install.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power monitoring device for a hydroelectric substation that is easy to install, comprising a monitoring base, a slot at the bottom of the monitoring base, a fixed frame slidably connected inside the slot, a monitoring device at the bottom of the fixed frame, symmetrical grooves inside the slot, and a locking block slidably connected inside the groove, symmetrical slots at both ends of the fixed frame, the slots and locking blocks being adapted to each other, a cavity inside the monitoring base, a rotating disk rotatably connected inside the cavity, a bevel gear one fixedly installed at the top of the rotating disk, a through groove at the top of the groove, and a connecting shaft fixedly installed at the top of the locking block, symmetrical arc grooves at the bottom of the rotating disk, the connecting shaft being adapted to the arc groove one, and a bevel gear two rotatably connected inside the cavity, the bevel gear two meshing with the bevel gear one.

[0007] As a further embodiment of this utility model: a mounting shell is fixedly installed at one end of the monitoring mounting base, a rotating handle is rotatably connected to one end of the mounting shell, and a rotating shaft is fixedly installed at one end of the bevel gear, with the rotating shaft passing through the mounting shell and the rotating handle for fixed installation.

[0008] As a further embodiment of this utility model: a ratchet is rotatably connected inside the mounting housing, and the ratchet is fixedly installed with the rotating shaft; a pawl is rotatably connected inside the mounting housing.

[0009] As a further improvement of this utility model: a fixing rod is fixedly installed inside the mounting shell, and a return spring is fixedly installed between the fixing rod and the middle of the pawl.

[0010] As a further improvement of this utility model: one end of the mounting shell is provided with an arc-shaped groove, and one end of the pawl is fixedly installed with a connecting rod, which is connected to the arc-shaped groove.

[0011] As a further improvement of this utility model, a fixed platform is slidably connected to the top of the monitoring fixed base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model drives bevel gear one and bevel gear two by rotating the handle, which in turn drives the rotating disk to rotate. The arc groove and the connecting shaft cooperate to make the locking block slide into the slot, forming a double-sided fixation. Compared with single-sided fixation, this symmetrical structure can evenly distribute external forces and effectively resist the torque generated by the rotation of the camera device or the impact of external forces, preventing the device from tipping over. Its mechanical transmission structure is simple and can be installed without complicated tools, ensuring the stable operation of the monitoring equipment of the hydropower substation and reducing the risk of equipment damage caused by unstable installation.

[0014] During installation, the pawl automatically engages with the tooth groove as the ratchet rotates, forming a one-way stop. This effectively prevents the shaft from rotating in the opposite direction and prevents the locking block from exiting the groove, thus avoiding loosening or falling off the device due to external force. During disassembly, simply pull the connecting rod to disengage the pawl from the ratchet, and the limit switch can be easily released. The operation is simple and requires no additional power source. It achieves automatic locking and quick unlocking through its mechanical structure, adapting to vibration environments such as hydroelectric power substations, ensuring long-term stable operation of monitoring equipment, and reducing maintenance difficulty.

The top of the sliding groove 6 has a through groove 8, and a connecting shaft 9 is fixedly installed at the top of the locking block 7. The bottom of the rotating disk 11 has symmetrically opened arc-shaped grooves 21, and the connecting shaft 9 is adapted to the arc-shaped grooves 21. A bevel gear 13 is rotatably connected inside the cavity 10, and the bevel gear 13 meshes with the bevel gear 12.

[0025] The above scheme is adopted: the monitoring device 4, the fixing frame 3, the slot 2 and the fixing base 1 are all prior art referenced in the prior art documents and are not described in detail in this application. The card block 7 is made of steel and fits with the card slot 5. The fixing frame 3 is made of steel and the edge of the card slot 5 is rounded. The rotating disk 11 is made of 45# steel and fits with the bearing inside the cavity 10. The first bevel gear 12 and the second bevel gear 13 are both made of carburized steel. The arc groove 21 guides the connecting shaft 9 to slide, so as to realize the synchronous extension and retraction of the card block 7.

[0026] Reference Figures 1 to 6The monitoring mounting base 1 has a mounting shell 14 fixedly installed at one end, and a rotating handle 16 is rotatably connected to one end of the mounting shell 14. The bevel gear 13 has a rotating shaft 15 fixedly installed at one end, and the rotating shaft 15 passes through the mounting shell 14 and the rotating handle 16 for fixed installation.

[0027] The above scheme is adopted: the mounting shell 14 is made of cast aluminum, the rotating handle 16 is made of PA66+30%GF material with knurled surface treatment, and is connected to the rotating shaft 15 (40Cr steel) by a flat key. The rotating shaft 15 and the mounting shell 14 are supported by bearings.

[0028] Reference Figures 1 to 6 The mounting housing 14 is rotatably connected to a ratchet 17, and the ratchet 17 is fixedly installed with the rotating shaft 15. The mounting housing 14 is rotatably connected to a pawl 18. The mounting housing 14 is fixedly installed with a fixing rod 19, and a return spring 20 is fixedly installed in the middle of the fixing rod 19 and the pawl 18. One end of the mounting housing 14 is provided with an arc-shaped groove 22. One end of the pawl 18 is fixedly installed with a connecting rod 23, and the connecting rod 23 is connected to the arc-shaped groove 22.

[0029] The above scheme is adopted: the ratchet 17 is made of 45# steel and cooperates with the rotating shaft 15; the pawl 18 is made of spring steel and is rotatably connected to the fixing rod 19 through a cylindrical pin; the return spring 20 is made of stainless steel and provides clamping force for the pawl 18; the arc groove 22 cooperates with the connecting rod 23; when the handle 16 is turned clockwise, the ratchet 17 rotates freely; when it is turned counterclockwise, the pawl 18 is engaged in the tooth groove of the ratchet 17 under the action of the return spring, realizing one-way locking; when unlocking is required, the connecting rod 23 is pulled to slide along the arc groove 22, so that the pawl 18 disengages from the ratchet 17, at which time the handle can rotate freely.

[0030] Reference Figures 1 to 6 The top of the monitoring mounting base 1 is slidably connected to a mounting platform 24;

[0031] The above-mentioned solution is adopted: the fixed platform 24 is the prior art mentioned in the referenced prior art documents, and is not described in detail in this application.

[0032] The working principle of this utility model is as follows: When installing the monitoring device 4, the fixing bracket 3 is inserted into the slot 2 of the monitoring fixing base 1. At this time, the slots 5 at both ends of the fixing bracket 3 correspond to the positions of the sliding grooves 6 in the slot 2. The rotating handle 16 at one end of the mounting shell 14 is rotated. The rotating handle 16 drives the bevel gear 13 to rotate through the rotating shaft 15. Since the bevel gear 13 meshes with the bevel gear 12, the bevel gear 12 rotates accordingly, driving the rotating disk 11 to rotate in the cavity 10. The arc-shaped groove at the bottom of the rotating disk 11... The 21-21 engages with the connecting shaft 9 at the top of the locking block 7. As the rotating disk 11 rotates, the arc-shaped groove 21 pushes the connecting shaft 9, causing the locking block 7 to slide within the sliding groove 6. The locking block 7 gradually inserts into the locking groove 5, forming a symmetrical locking and fixing. This double-sided locking design, compared to single-sided fixing, provides balanced and symmetrical support for the monitoring device 4. When the camera device rotates to the non-fixed side or is subjected to external impact, the engagement of the locking blocks 7 on both sides with the locking groove 5 can effectively distribute the force, preventing the device from tipping over around the fixed point and ensuring the stability of the monitoring device. After installation, the ratchet 17 rotates synchronously with the shaft 15. The pawl 18 is installed inside the mounting housing 14 via the fixing rod 19 and the return spring 20. When the shaft 15 drives the ratchet 17 to rotate clockwise in the installation direction, the pawl 18 slides on the back of the ratchet 17 teeth and rotates around the fixing rod 19 due to the pressure from the inclined surface of the teeth, compressing the return spring 20. When the ratchet 17 rotates through a certain angle, the pawl 18 is engaged in the tooth groove of the ratchet 17 under the elastic force of the return spring 20. At this time, if the shaft 15 is subjected to counterclockwise rotation... When an external force is applied in the disassembly direction, the pawl 18 will lock the teeth of the ratchet 17, preventing it from rotating in the opposite direction. This restricts the rotation of the shaft 15 and the bevel gears 13 and 12 connected to the shaft, preventing the rotating disk 11 from reversing. Consequently, the locking block 7 cannot exit from the slot 5, thus limiting and fixing the monitoring device 4. If disassembly is required, the connecting rod 23 at one end of the pawl 18 will slide within the arc-shaped groove 22, causing the pawl 18 to disengage from the tooth groove of the ratchet 17, thereby releasing the limit and facilitating the disassembly of the monitoring device.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
