[0021] In order to make those skilled in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0022] Please refer to Figure 1 and Figure 2 Among them, Figure 1 The structural schematic diagram of the simple integrated pipeline liquid detection device provided by the embodiments of the present application is shown in Figure 2 The structural schematic diagram of the simple integrated pipeline liquid detection device provided by the embodiments of the present application is shown in Figure 1 The structural schematic diagram of the simple integrated pipeline liquid detection device provided by the embodiments of the present application is shown in

[0023] In a first specific embodiment, the application provides a simple integrated pipeline liquid detection device, comprising a rotary joint 1 and a detection body 5 connected to the rotary joint 1, the rotary joint 1 is used to connect to the pipeline to be detected and flow into the detection body 5 when the pipeline to be detected is abnormally blocked, and the detection body 5 is used to detect the presence of the leakage liquid.

[0024] The rotary joint 1 comprises a rotary joint oil inlet 9 and a rotary joint leakage outlet 10 arranged on the outer side, and further comprises a plurality of cavities arranged in the interior, the cavities comprise a rotary cavity 12 connected to the rotary joint oil inlet 9, a second cavity 16 connected to the rotary joint leakage outlet 10, and a first cavity 11 connected to the rotary cavity 12, the first cavity 11 is connected to the pipeline to be detected, and a communication cavity which is integrated and in communication with the first cavity 11 and the rotary cavity 12 is provided with an elastic member between the communication cavity and the second cavity 16, the elastic member can be bent and deformed, and in the natural state, the elastic member separates and blocks the communication cavity and the second cavity 16, and in the bent state, a gap 15 is generated and the communication cavity and the second cavity 16 are in communication.

[0025] In this embodiment, the rotary joint 1 has different flow effects for the unobstructed and obstructed pipeline to be detected.

[0026] Specifically, the rotary joint 1 is connected to the pipeline to be detected, so that the liquid flowing into the rotary joint 1 through the rotary joint oil inlet 9 can flow back to the pipeline to be detected through the first cavity 11. When the pipeline to be detected is unobstructed, the rotary joint oil inlet 9 is filled with liquid, and the liquid flows back to the pipeline to be detected through the rotary cavity 12 and the first cavity 11 in turn, and the elastic member separates and blocks the communication cavity and the second cavity 16, so that the liquid cannot enter the second cavity 16 and flow into the detection body 5, and the detection body 5 cannot detect the leakage liquid, so there is no abnormal obstruction of the pipeline to be detected; when the pipeline to be detected is blocked, the rotary joint oil inlet 9 is continuously filled with liquid, and the liquid cannot flow back to the pipeline to be detected through the first cavity 11, and the liquid that cannot flow back flows back to the first cavity 11, and the liquid that is retained in the first cavity 11 is blocked in the communication cavity together with the liquid that continuously flows into the rotary cavity 12, the pressure of the communication cavity connected to the first cavity 11 and the rotary cavity 12 increases, the liquid in the communication cavity applies force to the elastic member, the elastic member is bent and deformed, a gap 15 appears between the communication cavity and the second cavity 16, and the liquid can flow into the second cavity 16 and flow into the detection body 5 through the oil inlet pipe 2 connected to the rotary joint leakage outlet 10, and the detection body 5 detects the leakage liquid, so there is an abnormal obstruction of the pipeline to be detected.

[0027] In the embodiment, the elastic member can be made of a common elastic material such as rubber, with one end of the elastic member fixed and the other end of the elastic member contacting the seal in the static state to achieve the isolation of the communication cavity and the second cavity 16; when the pressure of the communication cavity becomes larger than the pressure of the second cavity 16, the liquid pushes the other end of the elastic member to swing and bend to expose the gap 15 to achieve the communication between the communication cavity and the second cavity 16.

[0028] In addition, the elastic member can also be in the form of a combination of a rotating pressure ring 13 and a return spring 14, the rotating pressure ring 13 is arranged between the second cavity 16 and the communication cavity, and the return spring 14 is connected with the rotating pressure ring 13; when the pipeline to be detected is abnormally blocked, the pressure of the closed cavity is greater than the pressure of the return spring 14, the liquid filled in the rotating cavity 12 acts on the rotating pressure ring 13, the rotating pressure ring 13 makes the return spring 14 in a compressed state, at this time the position of the gap 15 appears a gap, and the liquid in the rotating cavity 12 will flow into the second cavity 16 from the gap 15 and flow out from the leakage outlet 10 of the rotating joint.

[0029] In the embodiment, the main structure of the rotating joint 1 is a rotating body, in which the central axes of the first cavity 11, the rotating cavity 12, the second cavity 16 and the rotating pressure ring 13 are collinear.

[0030] In addition, the detection body 5 is used to detect the presence or absence of liquid, and the detection means used by the detection body 5 belongs to the prior art; for example, a shell with an inner cavity is used, so that the oil leakage inlet pipe 2 connected with the leakage outlet 10 of the rotating joint communicates with the inner cavity of the shell, and an instrument for detecting the presence or absence of liquid is arranged in the shell, so that when liquid appears in the detection body 5, it can be judged in time and an alarm can be sent.

[0031] In a specific embodiment, the detection body 5 includes a shell, the shell is provided with an inlet pipe joint 3 and an outlet pipe joint 7, the shell is provided with a detection flow channel communicating the inlet pipe joint 3 and the outlet pipe joint 7, and the shell is further provided with a sensing switch 4 for detecting the liquid in the detection flow channel, and the sensing switch 4 is connected with a PLC.

[0032] In the embodiment, in order to discover the leakage phenomenon in the first time, the oil leakage inlet pipe 2 is connected to the leakage outlet 10 of the rotating joint, and the other end of the oil leakage inlet pipe 2 is connected to the inlet pipe joint 3 on the detection body 5.

[0033] For example, the detection flow channel includes a first cavity 51 communicating with the inlet pipe joint 3, a fourth cavity 54 communicating with the outlet pipe joint 7, and a second cavity 52 communicating the first cavity 51 and the fourth cavity 54, and the fourth cavity 54 is located above the first cavity 51.

[0034] In the embodiment, the leaking liquid flows into the first cavity 51 through the inlet pipe joint 3, then into the second cavity 52, and then into the fourth cavity 54, and finally flows out through the outlet pipe joint 7 and the oil discharge outlet pipe 8 connected with the fourth cavity 54, and the upper side of the second cavity 52 is provided with the threaded plug 6. The number and form of the inductive switch 4 can be selected according to the needs, for example, the inductive switch 4 is arranged in each of the cavities, and the inductive switch 4 is connected with the PLC to transmit the liquid detection information at different positions; or the inductive switch 4 is arranged in a specific cavity.

[0035] The inductive switch 4 is an instrument for detecting the presence or absence of liquid, the composition of liquid, and the volume of liquid in the prior art, and the detection principle and setting structure do not belong to the improvement content of the present application. For example, the inductive switch 4 can adopt a contact liquid detection mode or a non-contact liquid detection mode, more specifically, a detection instrument with an inductive shaft or an infrared inductive detection instrument. For specific description, please refer to the prior art, which will not be repeated here.

[0036] For example, the detection flow channel further comprises a third cavity 53 in communication with the second cavity 52, the third cavity 53 is located above the first cavity 51 and below the fourth cavity 54, and the inductive switch 4 is arranged in the third cavity 53.

[0037] In the embodiment, the liquid flows through the first cavity 51, then enters the second cavity 52, and when the liquid enters the third cavity 53, the inductive shaft of the inductive switch 4 senses the presence of the liquid, thereby transmitting data to the PLC and issuing an alarm.

[0038] It should be emphasized that the key point of the present application is to add the simple integrated pipeline liquid detection device to the pipeline to be detected, so as to timely know the leakage amount of the oil or water in the leaking pipeline, and the inductive switch 4 feeds back to the PLC, so as to judge the sealing abnormality of the entire oil or water pipeline, and make the earliest judgment. Similarly, it can also detect whether the machining tool such as the internal cooling tool breaks during machining, whether the iron filings block the cooling hole, and other abnormal conditions.

[0039] It should be noted that in the present specification, the relationship terms such as first and second are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between the entities.
