DETAILED DESCRIPTION

[0024] 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.

[0025] 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.

[0026] 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 does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1, reference Figure 1~Figure 5, is the first embodiment of the utility model, which provides a fault detection device for a plunger pump. The fault detection device for a plunger pump includes a connecting assembly 200, including a connecting pipe 201a, a sealing gasket 201b, an adjusting sleeve 201c, a driving handle 201d, a driving ring 201e, a movable frame 201f and a push rod 201g. The sealing gasket 201b is arranged in the connecting pipe 201a, the adjusting sleeve 201c is rotatably connected to the surface of the connecting pipe 201a, the driving handle 201d is fixed to the surface of the adjusting sleeve 201c, the driving ring 201e is rotatably connected to the adjusting sleeve 201c through a thread, the movable frame 201f is fixed to the inner wall of the driving ring 201e, and the push rod 201g is hinged to the surface of the movable frame 201f.

[0028] The connecting pipe 201a is used to fix the sealing gasket 201b, and the sealing gasket 201b can improve the sealing performance of the connection between the fault detection device and the plunger pump. The adjusting sleeve 201c is used to drive the driving ring 201e to move. By rotating the driving handle 201d, the driving handle 201d can drive the adjusting sleeve 201c to rotate, thereby driving the driving ring 201e to move, so that the driving ring 201e drives the push rod 201g to move through the moving frame 201f. There are 8 push rods 201g on the driving ring 201e.

[0029] Specifically, the connecting assembly 200 also includes an extrusion member 202, including a support plate 202a, a compression spring 202b and a reset plate 202c. The support plate 202a is fixed to one side of the movable frame 201f, and the two ends of the compression spring 202b are respectively fixed to one side of the support plate 202a and the inner wall of the top rod 201g, and the reset plate 202c is fixed to the inner wall of the connecting tube 201a.

[0030] The support plate 202a is used to fix and support the compression spring 202b. The compression spring 202b is in a compressed state. The elastic force of the compression spring 202b can push the push rod 201g. When the push rod 201g moves toward the reset plate 202c, the reset plate 202c can squeeze the push rod 201g, so that the moving ends of multiple push rods 201g move toward the inner wall of the adjustment sleeve 201c.

[0031] Specifically, the connection assembly 200 further includes a positioning member 203, including a support block 203a and a rotating plate 203b, the support block 203a is fixed to the surface of the connection pipe 201a, and the rotating plate 203b is rotatably connected to the support block 203a.

[0032] The supporting block 203a is used to support the rotating plate 203b so that the rotating plate 203b can rotate flexibly.

[0033] Specifically, the positioning member 203 also includes a clamping block 203c and a positioning block 203d. The clamping block 203c is fixed to the surface of the connecting pipe 201a, and the positioning block 203d is fixed to the end of the rotating plate 203b. A positioning groove U is opened on one side of the adjustment sleeve 201c, and the clamping block 203c is located in the positioning groove U.

[0034] An inclined surface is provided at the end of the clamping block 203c. The clamping block 203c is inserted into the positioning groove U to clamp the adjusting sleeve 201c, so that the adjusting sleeve 201c can rotate in one direction, thereby preventing the connection between the fault detection device and the plunger pump from loosening. The positioning block 203d is used to provide limited support for the rotating plate 203b to prevent the adjusting sleeve 201c from having excessive torque, thereby deviating the rotating plate 203b, and improving the stability of the clamping block 203c in positioning the adjusting sleeve 201c.

[0035] Specifically, the positioning member 203 further includes a pressing plate 203e and a supporting spring 203f. The pressing plate 203e is fixed to one side of the rotating plate 203b. Two ends of the supporting spring 203f are respectively fixed to one side of the pressing plate 203e and the surface of the connecting pipe 201a.

[0036] The support spring 203f is in a compressed state and is used to support the pressure plate 203e. By pressing the pressure plate 203e, the pressure plate 203e can drive the rotating plate 203b to rotate, so that the rotating plate 203b drives the clamping block 203c away from the positioning groove U, thereby releasing the limit on the adjustment sleeve 201c.

[0037] Example 2, reference Figure 1~Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0038] Specifically, a detection mechanism 204 is fixed on the connecting pipe 201a.

[0039] The detection mechanism 204 is provided with vibration sensors, temperature sensors, pressure sensors, etc. to comprehensively capture various physical parameters of the plunger pump during operation. Some external characteristic signals of the plunger pump, such as vibration, temperature, etc., can be collected. By analyzing and processing these signals, it is possible to quickly determine that a certain fault has occurred in the pump to avoid losses. The various sensors provided in the detection mechanism 204 and the detection principles of the sensors are all existing technologies, which are clearly known to those skilled in the art and will not be elaborated here.

[0040] Specifically, the main body assembly 100 includes a plunger pump body 101 and a fixing pipe 102 . The plunger pump body 101 is located at one side of the connecting pipe 201 a , and the fixing pipe 102 is fixed inside the plunger pump body 101 .

[0041] There are two fixed pipes 102, which are respectively located at the liquid input port and the liquid output port of the plunger pump body 101. The fixed pipes 102 of different types of plunger pumps have different sizes.

[0042] Specifically, the main body component 100 further includes an extrusion ring 103 , and the extrusion ring 103 is fixed to the surface of the fixed tube 102 .

[0043] The size of the extrusion ring 103 varies with the size of the fixed tube 102. The extrusion ring 103 is pushed by multiple push rods 201g, so that the extrusion ring 103 drives the fixed tube 102 to be squeezed toward the sealing gasket 201b, thereby preventing liquid leakage from the connection between the fixed tube 102 and the connecting tube 201a. In addition, the multiple push rods 201g squeeze the extrusion ring 103 to ensure the stability of the fixed tube 102 and prevent the connection between the fixed tube 102 and the connecting tube 201a from shaking during the operation of the plunger pump body 101.

[0044] Specifically, a positioning ring 201h is fixed on the top of the connecting pipe 201a, and there are two positioning rings 201h.

[0045] The positioning ring 201h is used to position the adjusting sleeve 201c so that the adjusting sleeve 201c can stably rotate on the surface of the connecting pipe 201a.

[0046] Specifically, the end of the pressing plate 203e is provided with a chamfer.

[0047] During use, when it is necessary to connect the fault detection device and the plunger pump, the fixed tube 102 can be inserted into the connecting tube 201a. At this time, rotating the driving handle 201d can drive the adjusting sleeve 201c to rotate, so that the adjusting sleeve 201c drives the driving ring 201e to move, thereby causing the driving ring 201e to push the push rod 201g to move, so that the push rod 201g gradually moves away from the reset plate 202c. At this time, under the action of the reset elastic force of the compression spring 202b, the compression spring 202b can push the push rod 201g, so that the ends of multiple push rods 201g contact the surface of the fixed tube 102. At this time, as the driving ring 201e moves, the multiple push rods 201g can move toward the driving ring 201e, so that the driving ring 201e drives the fixed tube 102 to squeeze the sealing gasket 201b, thereby preventing liquid leakage at the connection between the fixed tube 102 and the connecting tube 201a.

[0048] If it is a plunger pump of different types, the size of the fixed tube 102 is different, and the push rod 201g can also adapt, so that the push rod 201g can squeeze the squeezing rings 103 of different sizes, thereby ensuring the connection between the fixed tube 102 and the connecting tube 201a.

[0049] When the adjusting sleeve 201c is rotated to connect the fixed tube 102 and the connecting tube 201a, the clamping block 203c can slide on one side of the plurality of positioning grooves U. When the fixed tube 102 and the connecting tube 201a are fixedly connected, the clamping block 203c is clamped in the positioning groove U, thereby limiting the adjusting sleeve 201c and preventing the adjusting sleeve 201c from loosening.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the technical solution of the utility model.
