Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection structures, in particular to a pipeline connection structure. Background Art

[0002] Pipelines are piping systems used to transport fluids (such as water, steam, gas, or chemicals) within power plants. Existing pipeline connections are simply connected to each pipeline using bolts and flanges, resulting in poor connection stability and sealing effects.

[0003] In the prior art, pipelines need to be regularly inspected and maintained to ensure that they are in good condition. However, when the existing pipeline connections become loose, no timely feedback can be given to alert the staff. This indicates that there is room for improvement. Therefore, a pipeline connection structure is proposed to solve the above problem. Utility Model Content

[0004] The purpose of this utility model is to provide a pipeline connection structure to address the above-mentioned shortcomings.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a pipeline connection structure, comprising:

[0006] Pipelines, the pipelines are connected by flanges and connecting bolts;

[0007] an early warning nut, the early warning nut being threadedly connected to the connecting bolt, and the connecting bolt being provided with an insulating strip;

[0008] The warning nut is provided with a warning light, a power supply, two sets of contact pieces arranged opposite to each other and a resistance spring for resisting the contact pieces;

[0009] The two groups of contact pieces are connected to the positive and negative poles of the power supply respectively;

[0010] Initially, the insulating strip separates the two groups of contact pieces on the connecting bolt from the connecting bolt, preventing them from forming a loop.

[0011] The contact piece is used to contact the connecting bolt when the warning nut and the connecting bolt are loose and misaligned, and the circuit is connected through the connecting bolt to enable the warning light to send out a warning message.

[0012] Furthermore, the contact pieces are provided in two groups, and the two groups of contact pieces are distributed on opposite sides of the warning nut;

[0013] The warning nut is provided with connection circuits corresponding to the two groups of contact pieces.

[0014] Furthermore, the end of the connecting bolt is provided with a placement groove corresponding to the insulating strip, and the placement groove is used to set the insulating strip.

[0015] Furthermore, a controller and a signal transmitter are also provided in the warning nut, and the controller and the signal transmitter are used to feed back abnormal signals to a remote terminal.

[0016] Furthermore, the contact piece is a metal piece with a conductive function, and the warning nut is provided with a mounting hole corresponding to the interference spring;

[0017] The resisting spring is used to push the contact piece to move toward the connecting bolt.

[0018] Furthermore, gaskets are provided between the pipes;

[0019] The gasket includes two groups of spring pieces, and the two groups of spring pieces are distributed in a V shape;

[0020] A sealing layer is provided between the two groups of spring pieces, and the sealing layer includes an isolation sheet provided on the spring piece on one side and a trigger seat provided on the spring piece on the other side;

[0021] The trigger seat is provided with an opening corresponding to the isolation piece, and the gasket is provided with an alarm corresponding to the trigger seat;

[0023] The beneficial effects of the present invention are as follows:

[0024] The utility model can preset an insulating strip on the connecting bolt in advance, and then after the early warning nut is installed, the contact piece contacts the insulating strip. At this time, the early warning light and the power supply line are not conductive. During the use of the pipeline, the early warning nut may become loose due to slight vibrations of the pipeline, thereby deflecting the early warning nut from the connecting bolt, so that the contact piece and the insulating strip are misaligned and offset. At this time, the contact piece is in direct contact with the connecting bolt, and the current passes through the connecting bolt, thereby making the circuit conductive. At this time, the early warning light sends out an early warning message and sounds an alarm to remind the maintenance personnel that the bolt is loose, so as to facilitate subsequent maintenance.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-5 The utility model discloses a pipeline connection structure, comprising:

[0038] Pipelines 01, said pipelines 01 are connected by flanges 011 and connecting bolts 012;

[0039] A warning nut 1, which is threadedly connected to the connecting bolt 012, and an insulating strip 3 is provided on the connecting bolt 012;

[0040] The warning nut 1 is provided with a warning light 11, a power supply 12, two sets of contact pieces 13 arranged opposite to each other, and a resistance spring 14 for resisting the contact pieces 13;

[0041] The two groups of contact pieces 13 are connected to the positive and negative electrodes of the power supply 12 respectively;

[0042] Initially, the insulating strip 3 separates the two groups of contact pieces 13 on the connecting bolt 012 from the connecting bolt 012 , preventing them from forming a loop.

[0043] The contact piece 13 is used to contact the connecting bolt 012 when the warning nut 1 and the connecting bolt 012 are loose and misaligned, and the circuit is connected through the connecting bolt 012 to enable the warning light 11 to send out a warning message.

[0044] When the present application is in use, an insulating strip 3 can be preset on the connecting bolt 012 in advance, and then after the early warning nut 1 is installed, the contact piece 13 contacts the insulating strip 3. At this time, the early warning light 11 and the power supply 12 circuit are not conductive. During the use of the pipeline, slight vibrations of the pipeline may cause the early warning nut 1 to loosen, thereby deflecting the early warning nut 1 from the connecting bolt 012, so that the contact piece 13 and the insulating strip 3 are misaligned. At this time, the contact piece 13 is in direct contact with the connecting bolt 012, and the current passes through the connecting bolt 012, connecting the positive and negative poles of the power supply 12 to form a loop, thereby making the circuit conductive. At this time, the early warning light 11 issues an early warning message and sounds an alarm to remind maintenance personnel that the bolt is loose, so as to facilitate subsequent maintenance.

[0045] In the present application, the contact pieces 13 are in two groups, and the two groups of contact pieces 13 are distributed on opposite sides of the warning nut 1;

[0046] The warning nut 1 is provided with connection circuits corresponding to the two groups of contact pieces 13 .

[0047] In a preferred embodiment, the end of the connecting bolt 012 is provided with a placement groove corresponding to the insulating strip 3, and the placement groove is used to place the insulating strip 3.

[0048] In actual application scenarios, the placement slot should be located inside or in the middle of the connecting bolt 012.

[0049] In a preferred embodiment, a controller and a signal transmitter are further provided in the warning nut 1, and the controller and the signal transmitter are used to feed back abnormal signals to the remote terminal so that the remote terminal can remotely warn and make adjustments after receiving the signal.

[0050] It should be noted that the contact piece 13 is a metal piece with a conductive function, and the warning nut 1 is provided with a mounting hole corresponding to the resistance spring 14;

[0051] The resisting spring 14 is used to push the contact piece 13 to move toward the connecting bolt 012 .

[0052] Finally, in another embodiment, if Figure 6 As shown, a gasket 2 is provided between the pipes 01;

[0053] The gasket 2 includes two groups of spring pieces 21, and the two groups of spring pieces 21 are distributed in a V shape;

[0054] A sealing layer 22 is provided between the two groups of elastic pieces 21. The sealing layer 22 includes an isolation sheet 221 provided on one side of the elastic piece 21 and a trigger seat 222 provided on the other side of the elastic piece 21.

[0055] The trigger seat 222 is provided with an opening corresponding to the isolation piece 221, and the gasket 2 is provided with an alarm corresponding to the trigger seat 222;

[0056] It is easy to imagine that the isolation sheet 221 is made of insulating material;

[0057] The positive and negative poles of the power supply of the alarm are set in the opening of the trigger seat 222, and the isolation piece 221 is set between the positive and negative poles of the power supply of the alarm, so that the power supply of the alarm is turned on and an early warning signal is issued when the isolation piece 221 is detached from the opening.

[0058] It should be noted that a connecting circuit is provided in the trigger seat 222, and a corresponding conductive sheet is provided in the opening. The conductive sheet is connected to the positive and negative poles of the power supply of the alarm. When the isolation sheet 221 is detached and opened, there is no obstruction between the conductive sheets, the two groups of conductive sheets are in contact, and the connecting circuit is turned on to trigger the alarm. Specifically, the conductive sheet can be a relatively curved metal spring sheet with conductive properties, which is used to connect the two conductive sheets when the isolation sheet 221 is detached.

[0059] With the above-mentioned structural arrangement, in addition to the warning of the above-mentioned connecting bolt 012 and the warning nut 1, the device can also provide a warning through the gasket 2. Specifically, when in use, when the pipelines 01 at both ends are relatively clamped, the isolation sheet 221 and the trigger seat 222 provided on the two sets of spring sheets 21 are in a fitted state, and the isolation sheet 221 is plugged into the trigger seat 222. The isolation sheet 221 is located between the two sets of conductive sheets, blocking the positive and negative poles of the power supply of the alarm from being connected;

[0060] When the pipes 01 at both ends are loose, the two sets of springs 21 move apart, so that the isolation piece 221 comes out from the inside of the trigger seat 222. At this time, the two sets of conductive sheets in the trigger seat 222 come into contact, and the positive and negative poles of the power supply of the alarm are connected and turned on, thereby triggering the alarm. It should be added that the trigger seat 222 should also have corresponding electrical components. Since they all belong to the existing technology, they are not described here one by one.

[0061] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0063] In addition, "plurality" means two or more.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
