Description

Technical Field

[0001] This invention relates to the technical field of external circulation oil pumps, and more particularly to an installation mechanism and an automatic control system for external circulation oil pumps. Background Technology

[0002] The generator set's push-guide bearing uses an external pump for external circulation cooling. During unit operation, the external circulation oil pump draws hot oil from the push-guide oil tank, filters it, and directs it to two coolers for cooling before returning it to the oil tank. The external circulation oil pump uses a mechanical seal for sealing, but leaks can occur after prolonged operation. Currently, there is no automatic monitoring device for leaks in the external circulation oil pump; leaks can only be detected during routine inspections. The pump is then manually stopped, and the front and rear manual valves are closed to reduce the amount of oil leakage. However, if the leakage is significant and goes unnoticed, the oil level in the push-guide oil tank will drop, threatening the unit's safety. A large amount of lubricating oil is discharged into the water tank, increasing the difficulty of cleaning and potentially polluting the environment.

[0003] In existing technologies, the monitor needs to be installed into the support frame by welding or other methods, which makes the installation process quite troublesome. The motor above needs to be lifted first, and then the support frame needs to be disassembled before installation can be carried out. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0036] Example 1, referring to Figures 1-8 In the first embodiment of the present invention, an installation mechanism is provided, which is installed within an oil pump unit 100. The oil pump unit 100 includes an oil pump 101, a support frame 102 mounted on the oil pump 101, and a motor 103 mounted on the support frame 102 and whose output end is connected to the oil pump 101. The installation mechanism includes a support unit 200 and an installation unit 300.

[0037] The support unit 200 includes a fixing component 201 disposed within the oil pump unit 100 and abutting against the inner wall of the oil pump unit 100, a clamping component 202 disposed on the fixing component 201 for driving the fixing component 201 to move, multiple support components 203 disposed on the fixing component 201, and multiple support arms 204 disposed on the support components 203 and rotatably disposed on the support components 203; the mounting unit 300 includes a connecting component 301 disposed on the support arm 204, a support rod 302 slidably disposed on the connecting component 301 and having multiple connecting grooves 302a, and a snap-fit ​​component 303 disposed on the connecting component 301 and snap-fitted to the support rod 302.

[0038] In existing technologies, installing the monitor requires lifting the motor 103 with hoisting equipment, removing the support frame 102 from the oil pump 101, and welding the monitor to the inner wall of the support frame 102. However, the limited dimensions of the inner wall of the support frame 102 make installation difficult, and the installation position is hard to adjust. Furthermore, the monitor is prone to collision during assembly. In this invention, the support unit 200 allows for simpler installation: after lifting the motor 103, the fixing component 201 is placed inside the support frame 102. By rotating the clamping component 202, the fixing component 201 expands and presses against the inner wall of the support frame 102. Then, the installation unit 300 with the corresponding monitor is installed onto the corresponding support arm 204. The position of the support arm 204 can be adjusted using the support component 203, facilitating installation.

[0039] Compared to the installation methods of existing technologies, the present invention only requires lifting the motor 103, and no other tools are needed during installation, enabling quick installation and disassembly. If the monitor is damaged, it can also be quickly removed. Since it is installed directly inside the support frame 102, there is no need to consider the problem of the monitor colliding with the oil pump 101.

[0040] Example 2, refer to Figures 1-8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the fixing component 201 includes multiple fixing blocks 201c that are all in contact with the inner wall of the clamping component 202, multiple sets of connecting rods 201b, each set having two rods that are rotatably mounted on one end of the fixing blocks 201c, and upper push sleeves 201a and lower push sleeves 201d that are rotatably mounted on the other ends of the two connecting rods 201b respectively.

[0041] Furthermore, the clamping assembly 202 includes a threaded sleeve 202a disposed on the upper push sleeve 201a, a hollow threaded post 202c slidably disposed inside the upper push sleeve 201a and threadedly connected to the threaded sleeve 202a, a clamping handle 202d disposed on the hollow threaded post 202c and abutting against the upper push sleeve 201a, and an elastic element 202b disposed on the outer periphery of the hollow threaded post 202c and connected at both ends to the threaded sleeve 202a and the upper push sleeve 201a respectively.

[0042] The support assembly 203 includes a support seat 203a mounted on the upper push sleeve 201a, a connecting seat 203b rotatably mounted on the support seat 203a and connected to the support arm 204, and a connecting bolt 203c threadedly connected to the support seat 203a and abutting against the connecting seat 203b. The support seat 203a supports the connecting seat 203b. Tightening the connecting bolt 203c fixes the connecting seat 203b. Loosening the connecting seat 203b allows it to rotate and adjust the position of the support arm 204, moving it into the upper push sleeve 201a. After adjustment, the connecting bolt 203c is tightened to fix the support arm 204.

[0043] During use, the fixing component 201 is placed into the support frame 102, and the clamping handle 202d is rotated. The clamping handle 202d drives the hollow threaded column 202c to rotate, and the hollow threaded column 202c is threadedly connected to the threaded sleeve 202a, thereby causing the hollow threaded column 202c to move downward. The hollow threaded column 202c drives the threaded sleeve 202a to move downward, pressing it on the upper push sleeve 201a, thereby pushing the upper push sleeve 201a downward, reducing the distance between the upper push sleeve 201a and the lower push sleeve 201d. The connecting rod 201b pushes the fixing block 201c to move, so that the fixing block 201c abuts against the inner wall of the support frame 102, thereby fixing the fixing component 201. When it is necessary to remove it, the clamping handle 202d is rotated in the opposite direction, so that the clamping handle 202d moves upward. At this time, the elastic element 202b pushes the upper push sleeve 201a to move upward, increasing the distance between the upper push sleeve 201a and the lower push sleeve 201d, thereby separating the fixing block 201c from the support frame 102, making it convenient to remove the fixing component 201.

[0044] The remaining structure is the same as that in Example 1.

[0045] Example 3, referring to Figures 1-8This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the support arm 204 includes a connecting arm 204a disposed on the connecting seat 203b, an arc-shaped arm 204b with one end disposed on the connecting arm 204a and having an arc structure, and a connector head 204c disposed on the other end of the arc-shaped arm 204b and connected to the connecting assembly 301. The connecting arm 204a is used to connect the arc-shaped arm 204b and the connecting bolt 203c. The arc-shaped arm 204b can be stored above the upper push sleeve 201a for easy storage. Furthermore, after rotating the upper push sleeve 201a, the position of the connector head 204c within the upper push sleeve 201a is adjustable without affecting the rotation of other arc-shaped arms 204b, thus facilitating the installation of multiple monitors for monitoring.

[0046] The connecting assembly 301 includes a fixing bolt 301c threadedly connected to the connector 204c, a connecting platform 301b disposed on the fixing bolt 301c, and a mounting seat 301a disposed on the connecting platform 301b; by screwing the fixing bolt 301c into the connector 204c, the orientation of the mounting seat 301a can be adjusted, and the mounting seat 301a and the fixing bolt 301c are connected through the connecting platform 301b.

[0047] Furthermore, the support rod 302 is provided with a snap-fit ​​groove 302b; the snap-fit ​​assembly 303 includes a rotating connecting block 303b rotatably mounted on the mounting base 301a, a snap-fit ​​claw 303a mounted on the rotating connecting block 303b and snap-fitting with the snap-fit ​​groove 302b, and an elastic element 303c mounted on the mounting base 301a and connected to the snap-fit ​​claw 303a.

[0048] During use, during assembly, the connecting component 301 is screwed into the connector 204c, which supports the connecting component 301 and fixes it in place. The support rod 302 is inserted into the mounting base 301a, and the level sensor 403b, temperature sensor 403c, and other monitors are then installed onto the support rod 302. Bolts can be easily screwed into the connecting groove 302a for easy connection and fine-tuning.

[0049] By pressing the locking claw 303a, the locking claw 303a is flipped, causing one end of the locking claw 303a to move out of the locking groove 302b, releasing the restriction on the support rod 302. This allows the support rod 302 to slide on the mounting base 301a, adjusting the position of the support rod 302 and thus adjusting the height of the monitor mounted on it. This adjustment can be made according to different monitors. After adjustment, the locking claw 303a is released, causing the elastic element 203c to push the locking claw 303a to flip, causing the locking claw 303a to engage with the elastic element 202b to fix the clamping assembly 202, thus completing the installation of the monitor.

[0050] The remaining structure is the same as that in Example 2.

[0051] Example 3, referring to Figures 1-8 This is the third embodiment of the present invention. This embodiment proposes a derivation of an automatic control system for an external circulation oil pump, including the aforementioned mounting mechanism, and further comprising:

[0052] The control unit 400 includes an oil tank 401 connected to the oil pump 101, control valves 402 disposed at both ends of the oil pump 101, and a monitoring component 403 disposed in the support frame 102 and communicatively connected to the control valves 402.

[0053] Furthermore, the control valve 402 includes an electric ball valve 402a disposed on the side of the oil pump 101 communicating with the oil tank 401, and an electric ball valve 402b disposed on the other side of the oil pump 101; the monitoring component 403 includes a liquid level sensor 403b and a temperature sensor 403c disposed in the support frame 102 and on the support rod 302, and a PLC controller 403a that is communicatively connected to the liquid level sensor 403b and the temperature sensor 403c and controlled by the control valve 402.

[0054] During operation, when the oil pump 101 leaks, the lubricating oil accumulates in the support frame 102, causing the oil level to rise rapidly. This is detected by the level sensor 403b. At this time, the level sensor 403b transmits the monitored data to the PLC controller 403a. The PLC controller 403a then controls the electric ball valves 402a and 402b to close, thereby shutting down the unit and preventing leakage.

[0055] When temperature sensor 403c monitors the temperature at the shaft seal position of oil pump 101, it detects a sudden temperature change that exceeds the set value. If this occurs, the PLC controller 403a will control electric ball valves 402b and 402a to close, shutting down the unit and preventing leakage. Triggering either level sensor 403b or temperature sensor 403c will close control valve 402.

[0056] In actual use, multiple units are prepared, with units 1-4 in normal operation and units 5-6 in standby. If any of units 1-4 malfunctions, the electric ball valves 402a and 402b of that unit will be closed, and any one of units 5-6 will be activated. At the same time, inspection personnel will be notified to conduct an inspection, thus enabling real-time monitoring and preventing the reduction of oil in the oil tank due to leakage.

[0057] The remaining structure is the same as that in Example 3.
