Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a boiler pipeline leakage detection device and a detection method thereof. Background Art

[0002] Boiler pipes are pipes used to transport water, steam, fuel or other media in the boiler system. These pipes play a vital role in the operation of the boiler, ensuring the normal operation and high efficiency of the boiler. Boiler pipes include water feed pipes, steam pipes, exhaust pipes and fuel pipes.

[0003] Direct observation of boiler pipes can detect obvious leaks on boiler pipes, but less obvious leaks require detection equipment;

[0004] In order to save space in the boiler room, some boiler pipes in the boiler room are laid close to the wall. Therefore, when a boiler pipe laid close to the wall leaks, the existing boiler pipe leakage detection equipment is difficult to detect the side of the boiler pipe close to the wall, which causes limitations.

[0005] To this end, we propose a boiler pipeline leakage detection device and a detection method thereof. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a boiler pipeline leakage detection device and a detection method thereof, which overcome the deficiencies in the prior art and aim to solve the problems in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a boiler pipeline leakage detection device, comprising:

[0008] An installation frame, an inner installation block and an outer installation block; the inner installation block and the outer installation block are both installed on the installation frame; a detection piece No. 1 is installed on the inner installation block; the detection piece No. 1 is made of a flexible material; a detection pipe is fixedly connected to the detection piece No. 1;

[0010] Preferably, the inner mounting block and the outer mounting block are symmetrically rotatably connected with a rotating rod on both sides; the rotating rod is slidably connected with a telescopic rod; a telescopic electric push rod is rotatably connected between the telescopic rod and the rotating rod; the inner mounting block and the outer mounting block are both fixedly connected with a rotating motor; the output end of the rotating motor is fixedly connected with the rotating rod;

[0011] The four corners of the No. 1 detection piece are fixedly connected with connecting blocks; the connecting blocks are rotationally connected to the telescopic rod.

[0012] Preferably, the width of the No. 1 detection piece is greater than the widths of the inner mounting block and the outer mounting block.

[0013] Preferably, magnetic blocks are evenly fixed to the outer side of the No. 1 detection sheet.

[0014] The inner mounting block is extended into the gap between the pipe and the wall, and then the rotating rod and the telescopic rod drive the four corners of the No. 1 detection sheet so that the No. 1 detection sheet is covered on the surface of the pipe. When the pipe leaks, the leaked steam or water enters the piston cylinder through the detection pipe and triggers the spring switch. Therefore, the present invention can detect the side of the pipe close to the wall when the pipe is close to the wall.

[0015] Preferably, a sliding seat is fixedly connected to the No. 1 detection sheet; a sliding block is slidably connected to the sliding seat; an absorption layer is fixedly connected to the sliding block; an electrode sheet is fixedly connected to the absorption layer, and the absorption layer is made of an absorbent material, such as a sponge.

[0016] By setting an absorption layer on the first detection sheet, firstly, the installation frame of the present invention is quickly moved.

[0017] When the absorption layer detects that there is water on the pipeline, the installation frame of the present invention is slowly moved to specifically detect the leakage location, thereby shortening the detection time.

[0018] Preferably, a mounting plate is fixedly connected to the same side of the upper and lower ends of the mounting frame; the inner mounting block and the outer mounting block are evenly arranged on the corresponding mounting plate;

[0019] The upper and lower sides of the mounting plate are evenly rotatably connected with adjustment electric push rods; the output ends of the adjustment electric push rods are rotatably connected with the corresponding inner mounting block and the outer mounting block.

[0020] Preferably, a vertical detection unit is provided on the mounting plate corresponding to the outer mounting block; the vertical detection unit can extend between the outer mounting blocks to detect the two sides of two adjacent pipes; the vertical detection unit comprises a telescopic frame, a second detection sheet and an electromagnet block; the telescopic frame is fixedly connected to the mounting plate, a telescopic motor is fixedly connected to the telescopic frame, and an insertion rod is slidably connected to the telescopic frame; a screw rod is fixedly connected to the output end of the telescopic motor with a thread matching the insertion rod; the second detection sheet is fixedly connected to the insertion rod; the electromagnet block is fixedly connected to the second detection sheet and is distributed in a mouth shape; the second detection sheet is provided with the same detection pipe, the sliding seat, the sliding block, the absorption layer and the electrode sheet as those on the first detection sheet;

[0021] An opening is formed on the mounting plate corresponding to the outer mounting block.

[0022] Preferably, two groups of the vertical detection units are arranged at the gaps between the outer mounting blocks; and the electromagnet blocks on the second detection sheet in the two groups of the vertical detection units are located on opposite sides.

[0023] Preferably, a curved elastic sheet is fixedly connected to one end of the second detection sheet away from the insertion rod.

[0024] A boiler pipeline leakage detection method is applicable to the above-mentioned boiler pipeline leakage detection device, and the steps of the method are as follows:

[0025] S1. The staff extends the mounting plate with the inner mounting block into the gap between the pipe and the wall, rotates the rotating rod, and the telescopic rod pulls the No. 1 detection piece, so that the No. 1 detection piece on the inner mounting block fits with the side of the pipe close to the wall. Similarly, the No. 1 detection piece on the outer mounting block fits with the side of the pipe away from the wall.

[0026] S2. Adjust the electric push rod to move the inner mounting block and the outer mounting block, adjust the position so that the inner mounting block and the outer mounting block are level with the pipeline, and perform leakage detection on the pipeline;

[0027] S3. The No. 2 detection sheet is extended between two adjacent pipes, the electromagnet block on the No. 2 detection sheet is energized, and the No. 2 detection sheet is attached to the sides of the two adjacent pipes that are close to each other; leakage detection is performed on the sides of the adjacent pipes that are close to each other.

[0028] Beneficial effects of the present invention:

[0029] 1. The present invention extends the inner mounting block into the gap between the pipe and the wall, and then the rotating rod and the telescopic rod drive the four corners of the No. 1 detection sheet, so that the No. 1 detection sheet covers the surface of the pipe. When the pipe leaks, the leaked steam or water enters the piston cylinder through the detection pipe and triggers the spring switch. Therefore, the present invention can detect the side of the pipe close to the wall when the pipe is close to the wall.

[0030] 2. The present invention sets an absorption layer on the first detection sheet, first quickly moves the installation frame of the present invention, and when the absorption layer detects that there is water on the pipeline, slowly moves the installation frame of the present invention to specifically detect the leakage location, thereby shortening the detection time.

[0040] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 5 and 7, a boiler pipe leakage detection device comprising:

[0042] An installation frame 1, an inner installation block 11 and an outer installation block 12; the inner installation block 11 and the outer installation block 12 are both installed on the installation frame 1; a No. 1 detection sheet 13 is installed on the inner installation block 11; the No. 1 detection sheet 13 is made of a flexible material, such as rubber; a detection pipe 14 is fixedly connected to the No. 1 detection sheet 13;

[0043] A piston cylinder 15 is fixedly connected to the mounting frame 1 ; a piston block 16 is slidably connected in the piston cylinder 15 , and a spring switch 17 is fixedly connected in the piston cylinder 15 ; the other end of the detection pipeline 14 is fixedly connected and communicated with an end of the piston cylinder 15 away from the spring switch 17 .

[0044] In the present invention, the inner mounting block 11 and the outer mounting block 12 are symmetrically connected to the rotating rod 2 on both sides; the rotating rod 2 is slidably connected to the telescopic rod 21; the telescopic electric push rod 22 is rotatably connected between the telescopic rod 21 and the rotating rod 2; the inner mounting block 11 and the outer mounting block 12 are both fixedly connected to the rotating motor 23; the output end of the rotating motor 23 is fixedly connected to the rotating rod 2;

[0045] The four corners of the No. 1 detection piece 13 are fixedly connected with connection blocks 24 ; the connection blocks 24 are rotationally connected to the telescopic rod 21 ; the No. 1 detection piece 13 is made of a flexible material, such as rubber.

[0046] In the present invention, the width of the first detection piece 13 is greater than the widths of the inner mounting block 11 and the outer mounting block 12 .

[0047] In the present invention, the outer side of the first detection piece 13 is evenly fixed with magnetic blocks 25 .

[0048] In the present invention, the staff moves the present invention and extends the inner mounting block 11 into the gap between the pipeline and the wall, so that the inner mounting block 11 and the outer mounting block 12 are respectively located at the inner and outer sides of the pipeline, and then the rotating motors 23 on the inner and outer mounting blocks 11 and 12 drive the corresponding rotating rods 2 to rotate, so that the two rotating rods 2 rotate in the direction of approaching each other, and then the telescopic electric push rod 22 pushes the telescopic rod 21 outward, so that the connecting block 24 moves with both sides of the No. 1 detection piece 13 toward both sides of the pipeline, so that the No. 1 detection piece 13 on the inner mounting block 11 covers the side wall of the pipeline close to the wall, and the No. 1 detection piece 13 on the outer mounting block 12 covers the side wall of the pipeline away from the wall, and then the staff moves the installation frame 1, so that the inner mounting block 11 and the outer mounting block 12 move with the corresponding No. 1 detection piece 13, when moved to the pipeline leakage position, the steam or water leaked in the pipeline enters the piston cylinder 15 through the detection pipe 14 on the No. 1 detection piece 13, pushing the piston block 16 to move, so that the spring switch 17 is squeezed and connected to the circuit, thereby detecting the leakage;

[0049] After the detection is completed, the piston block 16 is pushed back to its original position under the action of the spring switch 17's own elastic force;

[0050] In the present invention, the width of the No. 1 detection piece 13 is greater than the width of the inner mounting block 11 and the outer mounting block 12, and the side of the pipeline is arc-shaped, so that the width of the No. 1 detection piece 13 is larger when it is installed on the inner mounting block 11 and the outer mounting block 12, and it fits the arc-shaped side of the pipeline;

[0051] In the present invention, the first detection piece 13 is fixedly connected to the side away from the pipe, and the magnetic block 25 adsorbs the metal pipe, thereby squeezing the first detection piece 13, reducing the unevenness of the pipe surface, and causing the leaked steam or water to leak;

[0052] The present invention extends the inner mounting block 11 into the gap between the pipe and the wall, and then the rotating rod 2 and the telescopic rod 21 drive the four corners of the No. 1 detection piece 13, so that the No. 1 detection piece 13 is covered on the surface of the pipe. When the pipe leaks, the leaked steam or water enters the piston cylinder 15 through the detection pipe 14, triggering the spring switch 17, so that the present invention can detect the side of the pipe close to the wall when the pipe is close to the wall.

[0053] Refer to the instruction manual Figure 5 and 6 In the present invention, a sliding seat 3 is fixedly connected to the No. 1 detection sheet 13; a sliding block 31 is slidably connected to the sliding seat 3; an absorption layer 32 is fixedly connected to the sliding block 31; an electrode sheet 33 is fixedly connected to the absorption layer 32, and the absorption layer 32 is made of an absorbent material, such as a sponge.

[0054] In the present invention, when the pipeline leaks, the leaked steam or water adheres to the pipeline and spreads along the pipeline. An absorption layer 32 is set on the first detection sheet 13. The staff quickly moves the installation frame 1 of the present invention. The absorption layer 32 can absorb the steam or water leaking from the pipeline, thereby soaking the absorption layer 32, so that the electrode sheet 33 on the absorption layer 32 can communicate with the current, so that the absorption layer 32 detects the steam or water. Then the staff slowly moves the installation frame 1 of the present invention, and then the detection pipeline 14, the piston block 16 and the spring switch 17 detect the specific leakage location;

[0055] The present invention sets an absorption layer 32 on the first detection sheet 13, first quickly moves the installation frame 1 of the present invention, and when the absorption layer 32 detects that there is water on the pipeline, slowly moves the installation frame 1 of the present invention to specifically detect the leakage location, thereby shortening the detection time.

[0056] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 2 and 6 In the present invention, a mounting plate 4 is fixedly connected to the same side of the upper and lower ends of the mounting frame 1; the inner mounting block 11 and the outer mounting block 12 are evenly arranged on the corresponding mounting plate 4;

[0058] In the present invention, when the pipeline is not laid neatly, the size of the gap between the pipeline and the wall is inconsistent, so the output end of the electric push rod 41 is adjusted to drive the corresponding inner mounting block 11 and the outer mounting block 12 to move, so that the inner mounting block 11 and the outer mounting block 12 remain parallel to the pipeline, thereby preventing the pipeline from being laid unevenly and the No. 1 detection piece 13 not fitting with the pipeline.

[0063] In the present invention, a vertical detection unit is provided on the mounting frame 1, and the telescopic motor 54 drives the insertion rod 55 to move, so that the insertion rod 55 pushes the second detection piece 52 downward, so that the second detection piece 52 is inserted into the opening between the two pipes, and then the current is passed into the electromagnet block 53 close to the position where the second detection piece 52 and the pipe are closest, so that the second detection piece 52 fits the pipe at this position, and then the current is passed into the remaining electromagnet blocks 53 in turn, so that the second detection piece 52 fits on the pipe, so that the present invention can detect the side walls of two adjacent pipes that are close to each other;

[0064] In the present invention, two sets of vertical detection units are arranged between two adjacent pipes, and the electromagnet blocks 53 on the second detection sheets 52 on the two vertical detection units are located on opposite sides, so that the two second detection sheets 52 are adsorbed on the two sides of the two adjacent pipes close to each other, and the two sides of the two adjacent pipes close to each other are detected at the same time;
