Technical Field

[0001] The invention relates to the technical field of derived external circulation oil pumps, and in particular to a mounting mechanism and an automatic control system of a derived external circulation oil pump. Background Art

[0002] The derivation bearing of the motor unit adopts an external circulation cooling method with an external pump. During the operation of the unit, the derivation external circulation oil pump draws out the hot oil in the derivation oil tank, flows through the filter to two coolers for cooling and then returns to the oil tank. The derivation external circulation oil pump is sealed by mechanical seal. The seal will leak after long-term operation. At present, when the derivation external circulation oil pump leaks, there is no automatic monitoring device and it can only be discovered during inspection. Then the pump is stopped manually and the front and rear manual valves are closed to reduce the oil leakage. When the oil leakage is large and no one finds it, the oil level in the derivation oil tank will become low, which will also threaten the safety of the unit. A large amount of lubricating oil is discharged into the water wheel room, which increases the difficulty of cleaning and even pollutes the environment.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0035] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1, reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a mounting mechanism installed in an oil pump unit 100, the oil pump unit 100, including an oil pump 101, a support frame 102 disposed on the oil pump 101, and a motor 103 disposed on the support frame 102 and having an output end connected to the oil pump 101. The mounting mechanism includes a support unit 200, and a mounting unit 300

[0037] The support unit 200 includes a fixing component 201 disposed in 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, a plurality of support components 203 that are all disposed on the fixing component 201, and a plurality of support arms 204 that are rotatably disposed on the support components 203 corresponding to the support components 203; the installation unit 300 includes a connecting component 301 disposed on the support arm 204, a support rod 302 that is slidably disposed on the connecting component 301 and has a plurality of connecting grooves 302a, and a clamping component 303 disposed on the connecting component 301 and clamped with the support rod 302.

[0038] During use, when installing the monitor in the prior art, it is necessary to lift the motor 103 by a lifting device, then remove the support frame 102 from the oil pump 101, and install the monitor on the inner wall of the support frame 102 by welding. However, due to the limited size of the inner wall of the support frame 102, it is difficult to install it, and the installation position is difficult to adjust. In addition, the monitor is easy to collide during assembly. However, in the present invention, through the support unit 200, it is only necessary to lift the motor 103, put the fixing component 201 into the support frame 102, and rotate the clamping component 202 to expand the fixing component 201 and press it against the inner wall of the support frame 102, and then install the installation unit 300 equipped with the corresponding monitor on the corresponding support arm 204. The position of the support arm 204 can be adjusted by the support component 203, which is convenient for installation.

[0039] Compared with the installation method of the prior art, the present invention only needs to lift the motor 103, and no other tools are needed during installation. It can be quickly installed and disassembled. After the monitor is damaged, it can also be quickly removed. And because it is installed directly in the support frame 102, there is no need to consider the problem of causing the monitor to collide with the oil pump 101.

[0040] Example 2, reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a fixing assembly 201 includes a plurality of fixing blocks 201c that are all in contact with the inner wall of the clamping assembly 202, a plurality of groups of connecting rods 201b each of which has two connecting rods 201b rotatably disposed at one end of the fixing block 201c, and an upper push sleeve 201a and a lower push sleeve 201d that are rotatably disposed at the other ends of the two connecting rods 201b.

[0041] Furthermore, the clamping assembly 202 includes a threaded sleeve 202a arranged on the upper push sleeve 201a, a hollow threaded column 202c slidably arranged on the inner side of the upper push sleeve 201a and threadedly connected to the threaded sleeve 202a, a clamping handle 202d arranged on the hollow threaded column 202c and abutting against the upper push sleeve 201a, and an elastic member 202b arranged on the outer peripheral side of the hollow threaded column 202c and connected to the threaded sleeve 202a and the upper push sleeve 201a at both ends.

[0042] Among them, the support assembly 203 includes a support seat 203a arranged on the upper push sleeve 201a, a connecting seat 203b rotatably arranged 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 connecting seat 203b is supported by the support seat 203a. After tightening the connecting bolt 203c, the connecting seat 203b can be fixed. After loosening the connecting seat 203b, the connecting seat 203b can be rotated to adjust the position of the support arm 204 so that the support arm 204 moves into the upper push sleeve 201a. After the adjustment is completed, the connecting bolt 203c is tightened to fix the support arm 204.

[0043] During use, the fixing assembly 201 is placed into the support frame 102, and the clamping handle 202d is turned. The clamping handle 202d drives the hollow threaded column 202c to rotate, and the hollow threaded column 202c is threadedly connected with the threaded sleeve 202a, so that the hollow threaded column 202c moves downward, and the hollow threaded column 202c drives the threaded sleeve 202a to move downward and press on the upper push sleeve 201a, thereby pushing the upper push sleeve 201a to move 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 rests on the inner wall of the support frame 102, thereby fixing the fixing component 201; when it needs to be removed, the clamping handle 202d is rotated in the opposite direction to move the clamping handle 202d upward. At this time, the elastic member 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 easier to remove the fixing component 201.

[0044] The remaining structures are the same as those of Example 1.

[0045] Example 3, reference Figure 1-Figure 8, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the support arm 204 includes a connecting arm 204a arranged on the connecting seat 203b, an arc-shaped arm 204b with one end arranged on the connecting arm 204a and having an arc-shaped structure, and a connecting head 204c arranged on the other end of the arc-shaped arm 204b and connected to the connecting component 301; the connecting arm 204a is used to connect the arc-shaped arm 204b and the connecting bolt 203c, and the arc-shaped arc-shaped arm 204b can be stored above the upper push sleeve 201a for easy storage, and after rotating the upper push sleeve 201a, the position of the connecting head 204c in the upper push sleeve 201a can be adjusted without affecting the rotation of other arc-shaped arms 204b, thereby facilitating the installation of multiple monitors for monitoring.

[0046] The connecting assembly 301 includes a fixing bolt 301c threadedly connected to the connecting head 204c, a connecting platform 301b arranged on the fixing bolt 301c, and a mounting seat 301a arranged on the connecting platform 301b; by screwing the fixing bolt 301c into the connecting head 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, a snap-in groove 302b is provided on the support rod 302; the snap-in assembly 303 includes a rotating connecting block 303b rotatably provided on the mounting seat 301a, a snap-in claw 303a provided on the rotating connecting block 303b and snap-in with the snap-in groove 302b, and an elastic member 303c provided on the mounting seat 301a and connected with the snap-in claw 303a.

[0048] During use, when assembling, the connecting component 301 is screwed into the connecting head 204c, and the connecting component 301 is supported by the connecting head 204c, so that the connecting component 301 can be fixed, and the support rod 302 is inserted into the mounting seat 301a, and then the liquid level sensor 403b, temperature sensor 403c, and other monitors are respectively installed on the support rod 302, and the bolts can be easily screwed in through the connecting groove 302a, which is convenient for connection and can be fine-tuned.

[0049] By pressing the engaging claw 303a, the engaging claw 303a is flipped, so that one end of the engaging claw 303a is moved out of the engaging groove 302b, and the limit on the support rod 302 is released, so that the support rod 302 can slide on the mounting seat 301a. By adjusting the position of the support rod 302, the height of the monitor installed on the support rod 302 can be adjusted, and it can be adjusted according to different monitors. After the adjustment is completed, the engaging claw 303a is released again, so that the elastic member 2 303c pushes the engaging claw 303a to flip, so that the engaging claw 303a is clamped into the elastic member 1 202b to fix the clamping assembly 202, and the installation of the monitor is completed.

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

[0051] Example 3, reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and which provides a derivation external circulation oil pump automatic control system, including the above-mentioned installation mechanism, and also including,

[0052] The control unit 400 includes an oil tank 401 communicated with 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 in communication with the control valve 402 .

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

[0054] During use, when the liquid level sensor 403b monitors, when the oil pump 101 leaks, the lubricating oil gathers in the support frame 102, causing the liquid level of the lubricating oil to rise rapidly, which is then monitored by the liquid level sensor 403b. At this time, the liquid level sensor 403b transmits the monitored data to the PLC controller 403a, and the PLC controller 403a controls the electric ball valve 402a and the electric ball valve 402b to be closed, thereby closing the group of units to achieve the purpose of preventing leakage.

[0055] When the temperature sensor 403c is monitoring, the temperature of the oil pump 101 shaft seal position is detected by the temperature sensor 403c. When a sudden change in temperature is detected and the increase is greater than the set value, the PLC controller 403a will control the electric ball valve 402b and the electric ball valve 1 402a to close, thereby shutting down the unit to prevent leakage; when either the liquid level sensor 403b or the temperature sensor 403c is triggered, the control valve 402 will be closed.

[0056] In actual use, multiple groups of units will be prepared, among which units 1-4 are in normal operation and units 5-6 are in standby status. When one of units 1-4 fails, the electric ball valve 402a and electric ball valve 402b of the group will be closed, and any one of units 5-6 will be activated. At the same time, the inspection personnel will be notified to conduct inspection, so as to realize real-time monitoring and avoid the problem of reduced oil in the derivation oil tank due to leakage of the unit.

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