Description

Technical Field

[0001] This utility model relates to the technical field of turbine generator bearing lubrication testing equipment, and more specifically, to a turbine generator bearing lubrication status monitoring device. Background Technology

[0002] A turbine generator is a generator driven by a steam turbine or gas turbine. It is one of the key pieces of equipment in modern industry and the energy sector. As one of the three main units in a thermal power plant (along with the boiler and steam turbine), the turbine generator uses the principle of electromagnetic induction to convert the mechanical energy of the steam turbine or gas turbine into electrical energy output. Modern turbine generators are three-phase AC synchronous generators, which have the advantages of high efficiency, reliability, and low maintenance costs. They are widely used in industry, energy, transportation and other fields. A turbine generator mainly consists of two parts: a rotor and a stator. The rotor is connected to the turbine and generates electrical energy through high-speed rotation. The stator is fixed at the center of the turbine and converts the rotational power of the rotor into electrical energy through the principle of electromagnetic induction. In addition, the turbine generator also includes components such as steam nozzles and low-pressure cylinders. The steam nozzles are used to spray steam at high speed to generate rotational power, and the low-pressure cylinders compress the steam into high-pressure steam for the turbine. In engineering, the turbine generator is monitored during use to facilitate understanding and control of its bearing lubrication status.

[0003] However, existing real-time bearing lubrication status monitoring devices are prone to damage to their internal components during long-term use. These components are interdependent and interconnected, and replacing a single component involves a complex disassembly and reassembly process. When internal components are damaged, the entire monitor needs to be removed from its base to facilitate replacement or repair of the damaged components. Otherwise, continued use may lead to errors or even significant erroneous data in the monitoring data, interfering with the monitoring effect. Utility Model Content

[0004] The purpose of this invention is to overcome the limitations of existing bearing lubrication status real-time monitors, which require the monitor to be removed from the base for repair when damaged. This invention provides a turbine generator bearing lubrication status monitoring device that facilitates the disassembly, replacement, or repair of damaged monitoring components by operators.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A turbine generator bearing lubrication condition monitoring device is provided, including a monitor, a fixing frame, and a fixing block for locking and fixing the monitor. The monitor is provided with a mounting bracket, which is slidably connected to the fixing frame. After the mounting bracket and the fixing frame are slidably installed, they form a composite bayonet, and the fixing block is inserted into the composite bayonet.

[0007] During the operation of the above scheme, if the monitor is damaged during use, the staff can remove the fixing block from the composite bayonet, then hold the mounting bracket and slide the mounting bracket along the fixed bracket to remove the entire monitor for repair. After the repair is completed, the entire monitor is installed into the fixed bracket by sliding the mounting bracket along the fixed bracket. The mounting bracket and the fixed bracket form a composite bayonet, and the fixing block is inserted into the composite bayonet to lock the monitor. During the entire disassembly and assembly process, the damaged monitoring device only needs to be slid off the fixed bracket, which makes it convenient for the staff to replace or repair the damaged monitoring components.

[0008] Furthermore, the inner walls on both sides of the fixed frame are provided with slots, and the sides of the mounting frame are provided with protrusions. The protrusions are inserted into the slots and slide within the slots. When the mounting frame is slidably inserted into the fixed frame, the bottom of the mounting frame abuts against the bottom of the fixed frame, thus fixing the detector on the fixed frame.

[0009] Furthermore, the top of the protrusion is provided with a first latch, and the top of the slot is provided with a second latch. After the protrusion is inserted into the slot, the first latch is inserted into the second latch. The inner wall of the first latch is flush with the inner wall of the second latch to form the composite latch. Both the first latch and the second latch are through slots. After the protrusion is inserted into the slot, the two through slots of the first latch and the second latch form a composite slot. After the fixing block is inserted into the composite slot, the mounting bracket can be stably fixed.

[0010] Furthermore, the top of the mounting bracket is also provided with an operating part for pulling the monitor, and the operating part is located between the two protrusions; when the operator takes out the monitor, he can take it out by operating the operating part, which is convenient for the operator to operate.

[0011] Furthermore, the operating part is a through groove that runs through the mounting bracket; the operating part is a through groove, which allows the operator to easily place their fingers or tools in the groove, thereby making a stable and powerful pull, reducing the difficulty of operation, improving work efficiency, and making the whole replacement process smoother and more efficient.

[0012] Furthermore, the bottom of the fixed frame is provided with a support frame for mounting against the outside. The support frame includes a base rod and support rods located on both sides of the base rod. The support rods are slidably connected to the fixed frame. The support frame allows the detector to maintain a certain height, which facilitates the docking of the monitor with the bearing system.

[0013] Furthermore, the support rod is provided with an adjustment part, and the bottom of the fixed frame is provided with a limiting part. The limiting part is used to connect with the adjustment part and limit the support rod within the fixed frame. The adjustment part and the limiting part enable the operator to adjust the height of the monitor according to the actual height of the equipment, thereby facilitating subsequent monitoring.

[0014] Furthermore, the adjusting part consists of several grooves located on the support rod, and the limiting part is a slider that passes through the fixing frame and is inserted into the groove. The limiting part and the adjusting part can be configured as follows: the limiting part is a pin, and the adjusting part is a pin hole, with the pin inserted into the pin hole for limiting; or the adjusting part is a threaded hole, and the limiting part is a bolt, with the bolt threadedly connected to the threaded hole. By using the slider and groove configuration, the limiting can be completed by inserting the slider into the groove, resulting in a simple structure.

[0015] Furthermore, it also includes an anti-slip mat, which is fixedly connected to the bottom surface of the base rod. The anti-slip mat is provided with an installation groove, which is connected to the external base. The installation groove is fixed to the external base, and the anti-slip mat increases the friction between the base and the base rod to prevent tipping.

[0016] Furthermore, the monitor is equipped with several bearing monitoring elements, which are used to connect to external bearings; the several monitoring elements together constitute the monitor, which can monitor the operating status and parameter changes of the bearings in real time.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Includes a monitor and a fixing block. The monitor is equipped with a mounting bracket, which is slidably connected to the fixing bracket. After the mounting bracket and the fixing bracket are slidably installed, they form a composite bayonet. The fixing block is inserted into the composite bayonet. During the entire disassembly and assembly process, the damaged monitor only needs to be slid off the fixing bracket without disconnecting the monitor from the base, which makes it convenient for staff to replace or repair the damaged monitoring components.

[0019] 2. The top of the mounting bracket is also equipped with an operating part for sliding the monitor. The operating part is a through groove, which allows the operator to easily place their fingers or tools in the groove for stable and powerful pulling. This reduces the difficulty of operation and improves work efficiency, making the entire replacement process smoother and more efficient. Attached Figure Description

Figure 1 and 2 As shown, the device includes a monitor 100, a mounting bracket 200, and a fixing block 300 for locking and fixing the monitor 100. The monitor 100 is provided with a mounting bracket 110, which is slidably connected to the mounting bracket 200. After the mounting bracket 110 and the mounting bracket 200 are slidably installed, they form a composite bayonet 400, and the fixing block 300 is inserted into the composite bayonet 400.

[0029] Specifically, the inner walls on both sides of the fixed frame 200 are provided with slots 210, and the mounting frame 110 is provided with protrusions 111 on both sides. The protrusions 111 are inserted into the slots 210 and slide within the slots 210. After the mounting frame 110 is slidably inserted into the fixed frame 200, the bottom of the mounting frame 110 abuts against the bottom of the fixed frame 200, so that the detector is fixed on the fixed frame 200.

[0030] Specifically, the top of the protrusion 111 is provided with a first latch 410, and the top of the slot 210 is provided with a second latch 420. After the protrusion 111 is inserted into the slot 210, the first latch 410 is inserted into the second latch 420. The inner wall of the first latch 410 is flush with the inner wall of the second latch 420 and forms a composite latch 400. Both the first latch 410 and the second latch 420 are through slots. After the protrusion 111 is inserted into the slot 210, the two through slots of the first latch 410 and the second latch 420 form a composite slot. After the fixing block 300 is inserted into the composite slot, it can stably fix the mounting bracket 110.

[0031] The working principle of the turbine generator bearing lubrication condition monitoring device in this embodiment is as follows:

[0032] When the monitor 100 is damaged during use, the staff first removes the fixing block 300 from the composite bayonet 400, holds the mounting bracket 110, slides the protrusion 111 of the mounting bracket 110 along the slot 210 of the fixing bracket 200, removes the entire monitor 100 and performs maintenance.

The fixing block 300 is inserted into the composite slot 400. During the entire disassembly and assembly process, the damaged monitor only needs to be slidably disassembled from the fixing bracket 200 without disconnecting the fixed connection between the monitor and the base, which makes it convenient for staff to replace or repair the damaged monitoring components.

When the staff takes out the monitor 100, they can take it out by operating the operating part 112, which is convenient for the staff to operate.

[0037] Specifically, the operating part 112 is a through slot that passes through the mounting bracket 110; the operating part 112 is a through slot, which allows the operator to easily place their fingers or tools in the slot, thereby making a stable and powerful pull, reducing the difficulty of operation, improving work efficiency, and making the whole replacement process smoother and more efficient.

[0038] The working principle of the turbine generator bearing lubrication condition monitoring device in this embodiment is as follows:

[0039] When the monitor 100 is damaged during use, the operator first removes the fixing block 300 from the composite bayonet 400, holds the operating part 112, places a finger or tool into the groove of the operating part 112, and pulls the protrusion 111 of the mounting bracket 110 along the slot 210 of the fixing bracket 200 to remove the entire monitor 100 for inspection. After the inspection is completed, the operator slides the protrusion 111 of the mounting bracket 110 along the slot 210 to install the entire monitor 100 into the fixing bracket 200.

[0041] Example 3

[0042] This embodiment is the third embodiment of a turbine generator bearing lubrication condition monitoring device, such as... Figure 2 and 3 As shown, the difference from Embodiment 1 is as follows:

[0043] Specifically, the bottom of the fixed frame 200 is provided with a support frame 500 for mounting against the outside. The support frame 500 includes a bottom rod 510 and support rods 520 located on both sides of the bottom rod 510. The support rods 520 are slidably connected to the fixed frame 200. The support frame 500 enables the detector to maintain a certain height, which facilitates the docking of the monitor 100 with the bearing system.

[0044] Specifically, the support rod 520 is provided with an adjustment part 521, and the bottom of the fixed frame 200 is provided with a limiting part 220. The limiting part 220 is used to connect with the adjustment part 521 and limit the support rod 520 within the fixed frame 200. The setting of the adjustment part 521 and the limiting part 220 allows the staff to adjust the height of the monitor 100 according to the actual height of the equipment, thereby facilitating subsequent monitoring.

[0045] Specifically, the adjusting part 521 consists of several grooves located on the support rod 520, and the limiting part 220 is a slider that passes through the fixing frame 200 and is inserted into the groove. The limiting part 220 and the adjusting part 521 can be configured as follows: the limiting part 220 is a pin and the adjusting part 521 is a pin hole, with the pin inserted into the pin hole for limiting; or the adjusting part 521 is a threaded hole and the limiting part 220 is a bolt, with the bolt threadedly connected to the threaded hole.

According to the actual height of the equipment, the support bracket 500 is slid into the fixed bracket 200 from the bottom, so that the corresponding height adjustment part 521 is aligned with the limiting part 220 at the bottom of the fixed bracket 200. Then, it is slid into the limiting part 220, so that the slider-shaped limiting part 220 is inserted into the groove of the adjustment part 521. At this time, the support rod 520 of the support bracket 500 can no longer slide in the fixed bracket 200. Then, the bearing monitoring body 120 of the monitor 100 is connected to the external turbine generator bearing, and the support bracket 500 is placed on the external base. The anti-slip pad 600 abuts against the surface of the external base, and the mounting groove is connected to the protrusion of the base, thus completing the installation.

For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
