[0002] Pressure switches are required in many control devices and monitoring devices in hydropower stations. The normally open or normally closed contacts of the pressure switches are used to send signals.

At the same time, the disassembly and assembly of the pressure switch is generally through threaded connections. If multiple pressure switches need to be tested, the threaded connection method not only consumes a lot of time, but the repeated rotation operation will also cause certain damage to the staff's wrists.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0028] 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.
[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, 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.
[0030] Example 1
[0031] Reference Figure 1-6This embodiment provides a disassembly mechanism, including a connecting component 100, including a connecting column 101, a rotating sleeve 102 is provided on the outer shell of the connecting column 101, and a pushing ring 103 is embedded in the connecting column 101; a pressure switch 200, and a connecting plug 201 is provided at the bottom of the pressure switch 200; a detection component 300, including a mobile platform 301, the connecting component 100 is fixed on the mobile platform 301, and a filter 302 is provided on the mobile platform 301, the filter 302 is connected to the oil pump 303, and the oil pump 303 is connected to the test pipe 304.
[0032] Specifically, the connection component 100 is one of the interfaces on the test pipe 304 , so a plurality of connection components 100 can be simultaneously arranged on the mobile platform 301 to simultaneously detect a plurality of pressure switches 200 , thereby improving the detection efficiency of the pressure switches 200 .
[0033] Furthermore, by cooperating with the connecting component 100 and the connecting plug 201, the connecting plug 201 can be directly inserted into the connecting column 101, so that the pressure switch 200 can be quickly installed on the mobile platform 301, and the pressure switch 200 can be quickly removed only by rotating the rotating sleeve 102, thereby abandoning the traditional threaded connection, avoiding wrist fatigue caused by repeated tightening of the pressure switch 200 by the staff, and shortening the time for disassembly and assembly of the pressure switch 200, further improving the detection efficiency.
[0034] Preferably, testing oil is input into the testing component 300. During the testing process, the power provided by the oil pump 303 causes the testing oil to circulate in the test pipe 304. When the testing oil in the testing component 300 is used for a long time, oxidation and contamination problems may occur, resulting in a decrease in the performance of the testing oil. In order to avoid affecting the test result of the pressure switch 200, the testing oil needs to be replaced in time. By using the filter 302 provided in the testing component 300, the testing oil can be purified before entering the test pipe 304, which can increase the service life of the testing oil.
[0035] By providing this device, not only can the time required for disassembly and assembly of the pressure switch 200 be shortened, reducing damage to the staff, but also the manual pressurization and depressurization operations are unnecessary, thereby greatly improving the detection efficiency.
[0036] Example 2
[0037] Reference Figure 2-5, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a retaining ring 101a is provided at the bottom of the connecting column 101, a spring 101b is fixed on the retaining ring 101a, a locking hole 101c is evenly provided on the side wall of the connecting column 101, a locking bead 104 is provided in the locking hole 101c, a straight notch 101d is symmetrically provided on the side wall of the connecting column 101, and an annular groove 101e is provided at the bottom of the connecting column 101; a first locking groove 102a is evenly provided on the inner wall of the rotating sleeve 102, inclined surfaces 102a-1 are provided on both sides of the first locking groove 102a, an inclined notch 102b is symmetrically provided on the inner wall of the rotating sleeve 102, and a sealing ring 102c is provided at the bottom of the rotating sleeve 102; limiting columns 103a are symmetrically provided on the outer side of the pushing ring 103; a second locking groove 201a is evenly provided on the outer side of the connecting plug 201.
[0038] Specifically, the diameter of the retaining ring 101 a is smaller than the inner diameter of the connecting column 101 , and is used to limit the spring 101 b to prevent the spring 101 b from popping out of the connecting column 101 .
[0039] Preferably, the size of the first locking groove 102a on the rotating sleeve 102 is adapted to the size of the locking ball 104, and the diameter of the locking hole 101c is also adapted to the locking ball 104. When the connecting plug 201 is not inserted into the connecting column 101, the locking hole 101c is connected to the first locking groove 102a, and the locking ball 104 is located in the space formed by the locking hole 101c and the first locking groove 104, and is fixed by the restriction of the side wall of the push ring 103. The sealing ring 102c is embedded in the annular groove 101e, which can seal the connecting assembly 100 and prevent the detection oil from overflowing through the straight groove 101d.
[0040] Furthermore, the lower end of the push ring 103 abuts against the spring 101b. When the push ring 103 is pressed downward, the spring 101b will also be compressed under the action of the push ring 103. Moreover, the limiting column 103a passes through the straight slot 101d and is embedded in the oblique slot 102b, thereby limiting the push ring 103 to move only in the vertical direction through the straight slot 101d.
[0041] Furthermore, the diameter of the connecting plug 201 is adapted to the inner diameter of the connecting column 101. When the connecting plug 201 is inserted into the connecting column 101, the connecting plug 201 pushes the push ring 103 in. Since the limiting column 103a is embedded in the inclined groove 102b, the push ring 103 drives the rotating sleeve 102 to rotate while moving downward, and the locking ball 104 will be embedded in the second locking groove 201a. The depth of the second locking groove 201a is slightly larger than the radius of the locking ball 104.
[0042] In this embodiment, when the pressure switch 200 needs to be connected to the mobile platform 301, the connecting plug 201 is inserted into the connecting column 101. Since the inner diameters of the connecting plug 201 and the connecting column 101 are consistent, the connecting plug 201 will push the push ring 103 inward when inserted and compress the spring 101b. Since the limit column 103a is restricted in the straight slot 101d, the push ring 103 can only move vertically downward along the straight slot 101d. The column 103a is also embedded in the inclined groove 102b at the same time, so the downward movement of the push ring 103 will also cause the rotating sleeve 102 to rotate along the inclined groove 102b. During the rotation process, the rotating sleeve 102 pushes the locking ball 104 out of the first locking groove 102a through the inclined surface 102a-1. Since the restriction on the locking ball 104 is released after the push ring 103 moves downward, the locking ball 104 is pressed into the second locking groove 201a, and the connecting plug 201 is fixed by the locking ball 104.
[0043] When the detection is completed and the pressure switch 200 needs to be disassembled, it is only necessary to rotate the rotating sleeve 102. During the rotation of the rotating sleeve 102, the oblique notch 102b will also rotate, thereby driving the limit column 103a in the oblique notch 102b to move up again. Due to the rotation of the oblique notch 102b, the first locking groove 102a is connected with the lock hole 101c again. At this time, the range of movement of the lock ball 104 is increased, and it cannot be completely fixed. In addition, the lock ball 104 will be pushed outward during the upward movement of the push ring 103, so the lock ball 104 will be re-embedded in the first locking groove 102a. At the same time, under the action of the restoring force of the spring 101b, the push ring 103 will be completely pushed out, and the lock ball 104 will be re-fixed in the space formed by the first locking groove 102a and the lock hole 101c. At this time, the pressure switch 200 has also completed the unlocking process.
[0044] By providing the connection assembly 100, the pressure switch 200 can be quickly disassembled and assembled, and the operation of repeatedly twisting the pressure switch 200 is omitted, which not only improves the efficiency of detection but also reduces the labor loss of the staff.
[0045] Example 3
[0046] Reference Figure 6 , which is the third embodiment of the utility model. This embodiment provides a pressure switch detection platform. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a universal wheel 301a is provided at the bottom of the mobile platform 301, a control console 301b is provided on the side wall of the mobile platform 301, and an oil inlet 301c is provided on the mobile platform 301; an oil tank 301d is provided in the mobile platform 301, and the filter 302 is connected to the oil tank 301d; a one-way valve 304a is provided on the test pipe 304, and a pressure gauge 304b is also provided on the test pipe 304; an oil outlet 305 is provided at the end of the test pipe 304.
[0047] Specifically, the universal wheel 301a provided at the bottom of the mobile platform 301 can freely move the mobile platform, so as to facilitate the transportation of the detection component 300; the switch of the oil pump 303 can be controlled by the control console 301b, so as to control the pressurization and pressure relief operations of the detection process, making the detection more convenient and efficient.
[0048] Preferably, the detection oil is poured in from the oil inlet 301c and discharged from the oil outlet 305. Alternatively, an oil outlet pipeline may be opened at the bottom of the oil tank 301d to speed up the discharge of the oil.
[0049] Furthermore, the one-way valve 304a of the test pipeline 304 is started and stopped manually. When the staff finds that the value deviation on the pressure gauge 304b is too large, the one-way valve 304a is closed to interrupt the detection urgently and the test pipeline 304 is inspected.
[0050] In this embodiment, after the pressure switch 200 is installed, the oil pump 303 is started through the control console 301b. Under the action of the oil pump 303, the oil in the oil tank 301d enters the test pipe 304 after being processed by the filter 302. The performance of the pressure switch 200 is judged by observing the changes in the value of the pressure gauge 304b.
[0051] By providing the detection component 300, the detection process can be operated more conveniently and quickly, thereby improving the efficiency of the detection.

For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed.

[0053] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
