Description

Technical Field

[0001] This application relates to the technical field of leak detection equipment, and more specifically, to a leak detection device for heating pipelines. Background Art

[0002] A heating pipeline is a pipeline that starts from a boiler room, a direct-fired machine room, a heating center, etc. and sends the heat source to the building heat inlet. Due to the long pipeline length, the pipeline is composed of multiple short pipelines welded together. Under the long-term corrosion of the external environment, the joints of the heating pipeline are prone to cracking and leakage. Long-term leakage will cause a large amount of waste of heat source. In order to reduce the leakage risk of the heating pipeline, it is necessary to frequently perform leak detection operations on the joints of the heating pipeline. The existing leak detection method for heating pipelines generally uses the method of personnel holding a gas detector to patrol for detection. This detection method has low accuracy, is not convenient for real-time monitoring of the pipeline, and cannot give an alarm in time when the pipeline leaks. Especially for the pipelines exposed outside, it is very difficult to detect in time under the influence of external wind or temperature when detecting through the exposed gas detector. The monitoring efficiency and detection accuracy are relatively low and cannot meet the use requirements.

[0003] The prior art document with the publication number of CN 215722604 U provides a high-precision leak detection device for heating pipelines. The device is cooperated with a heating pipeline, a semi-circular pipe, a semi-annular groove, a rectangular box, a piston, a T-shaped positioning rod, an elastic rubber ball, a T-shaped insulating rod, a second copper sheet, a first copper sheet, an acoustic-optic alarm, a storage battery, a first mounting block, a second mounting block, a first groove, a card slot, an L-shaped clamping rod, a tension spring and a fixing block. At this time, two integral circular gaskets and two semi-circular pipes form a small sealed space. When there is a leakage at the joint between two heating pipelines, the leaked gas enters the sealed space and pushes the piston. The pushing force drives the piston to slide upward in the rectangular box and squeeze the elastic rubber ball, causing the elastic rubber ball to deform. The deformed elastic rubber ball drives the second copper sheet to move upward through the rectangular block to contact the first copper sheet. At this time, the acoustic-optic alarm is powered on to alarm and remind the personnel, achieving the purpose of timely warning and reminding the personnel when there is a slight leakage at the joint of two heating pipelines, and improving the detection efficiency and detection accuracy.

[0004] Although the above prior art solution can achieve the relevant beneficial effects through the structure of the prior art, there are still the following defects: The device can only trigger the monitoring by squeezing the elastic rubber ball. When the squeezing force is less than the deformation force of the elastic rubber ball, it will cause the problem that the monitoring cannot be triggered, resulting in a slow leak detection response and inability to respond quickly.

[0005] In view of this, we propose a leak detection device for heating pipelines. Utility Model Content

An audible and visual alarm and a GPS locator are fixed on the outer wall of the second protective sleeve, and two vertically arranged first copper sheets and second copper sheets are fixed on the inner wall of the second protective sleeve. The first copper sheet, the second copper sheet, the audible and visual alarm and the GPS locator are electrically connected.

[0010] By adopting the above technical solution, through the fixation of the first protective sleeve and the second protective sleeve, the inner flange can be protected, and when there is liquid leakage between the two sections of pipelines, for horizontally installed pipelines, the first copper sheet and the second copper sheet are placed at the lowest point; when the pipeline is vertically installed, the sides of the first copper sheet and the second copper sheet are inclined structures; therefore, after water leakage between the two sections of pipelines, the water leakage at any place will drop to the first copper sheet and the second copper sheet at the lowest point under the action of gravity, and the water droplets will electrically connect the first copper sheet and the second copper sheet. At this time, the first copper sheet, the second copper sheet, the audible and visual alarm, the GPS locator and the power supply form a loop, quickly completing the leak detection corresponding action, the audible and visual alarm alarms, and the GPS locator operates, facilitating the user to obtain the leakage location.

[0018] By adopting the above technical solution, the inner wall of the area between the second protective sleeve and the flange is a slope structure and is inclined towards the direction of the second copper sheet. Therefore, when the pipeline is vertically installed, the second protective sleeve is placed below, and the leaked liquid will flow along the slope of the second protective sleeve towards the second copper sheet and the first copper sheet, so as to facilitate the connection of the second copper sheet and the first copper sheet in series.

Detailed implementation manners

[0031] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0032] A heat supply pipeline leak detection device includes: a first protective sleeve 1 and a second protective sleeve 2 respectively sleeved on two sections of pipelines 5. The first protective sleeve 1 and the second protective sleeve 2 are detachable. Flanges 7 that abut against the inner flange 51 are integrally formed on the opposite sides of the first protective sleeve 1 and the second protective sleeve 2. A sound and light alarm 3 and a GPS locator 4 are fixed on the outer wall of the second protective sleeve 2. Two vertically arranged first copper sheets 8 and second copper sheets 9 are fixed on the inner wall of the second protective sleeve 2. The first copper sheet 8, the second copper sheet 9, the sound and light alarm 3, and the GPS locator 4 are electrically connected.

[0033] Refer to Figures 1 - 8, the first copper sheet 8, the second copper sheet 9, the sound and light alarm 3 and the GPS locator 4 are electrically connected in series with the power supply. Through the fixation of the first protective sleeve 1 and the second protective sleeve 2, the inner flange 51 can be protected. And when there is liquid leakage between the two sections of pipes 5, for the horizontally installed pipe 5, the first copper sheet 8 and the second copper sheet 9 are placed at the lowest point; when the pipe 5 is vertically installed, the sides of the first copper sheet 8 and the second copper sheet 9 are inclined structures. Therefore, after water leaks between the two sections of pipes 5, the leaked water at any place will drop to the first copper sheet 8 and the second copper sheet 9 at the lowest point under the action of gravity. The water droplet electrically connects the first copper sheet 8 and the second copper sheet 9. At this time, the first copper sheet 8, the second copper sheet 9, the sound and light alarm 3, the GPS locator 4 and the power supply form a loop, quickly completing the leak detection response action. The sound and light alarm 3 alarms, and at the same time the GPS locator 4 operates. The GPS locator 4 is responsible for receiving the signals of GPS satellites and calculating its own position information. The user downloads and installs the mobile APP matching the GPS locator 4 on the mobile phone or logs in to the corresponding monitoring platform to quickly locate the leak point. The flange 7 abuts against the area between the mounting hole of the outer flange 11 and the pipe 5, so that both the two outer flanges 11 and the mounting hole are placed in the sealed area formed after the first protective sleeve 1 and the second protective sleeve 2 are closed, so as to realize the secondary sealing of the connection of the pipe 5.

[0034] Outer flanges 11 are fixedly installed on the outer edges of the opposite sides of the first protective sleeve 1 and the second protective sleeve 2, and an outer sealing gasket 6 is provided between the two outer flanges 11.

[0035] Refer to Figure 5 and Figure 6 , through two groups of outer flanges 11, under the connection of the bolt and nut group, it is convenient for the disassembly and assembly of the first protective sleeve 1 and the second protective sleeve 2, and under the action of the outer sealing gasket 6, the sealing effect of the first protective sleeve 1 and the second protective sleeve 2 is improved.

[0036] A pointer 21 is rotatably connected to the outer wall of the second protective sleeve 2 in the axial direction, and a corresponding groove 22 parallel and corresponding to the second copper sheet 9 is opened on the outer wall of the second protective sleeve 2.

[0037] Refer to Figure 1 and Figure 2 , when the two sections of pipes 5 are horizontally installed, the pointer 21 is rotatably connected to the second protective sleeve 2. Under the action of gravity, when the pointer 21 coincides with the corresponding groove 22, the first copper sheet 8 and the second copper sheet 9 are at the lowest point position at this time, so as to facilitate the positioning of the first copper sheet 8 and the second copper sheet 9.

[0038] An inner sealing gasket 71 is provided between the flange 7 and the inner flange 51.

[0039] Refer to Figure 5 and Figure 6, through the inner sealing gasket 71, to improve the sealing effect when the flange 7 is fitted with the inner flange 51.

[0040] The inner wall of the second protective sleeve 2 is a slope structure and is inclined towards the direction of the second copper sheet 9.

[0041] Refer to Figure 5 , the inner wall of the area between the second protective sleeve 2 and the flange 7 is a slope structure and is inclined towards the direction of the second copper sheet 9. Therefore, when the pipeline 5 is installed vertically, the second protective sleeve 2 is placed below, and the leaked liquid will flow along the slope of the second protective sleeve 2 towards the second copper sheet 9 and the first copper sheet 8, so as to connect the second copper sheet 9 and the first copper sheet 8 in series.

[0042] Working principle: When the pipeline 5 is installed horizontally, rotate the first protective sleeve 1 and the second protective sleeve 2 so that the installation holes of the outer flange 11 correspond, and make the pointer 21 correspond and coincide with the corresponding groove 22, and then fix the first protective sleeve 1 and the second protective sleeve 2 through the bolt-nut group. When there is leakage between the two inner flanges 51, the water slides down under the action of gravity; when the pipeline 5 is installed vertically, the second protective sleeve 2 is placed below. At this time, there is no need to observe the position of the pointer 21, and only the first protective sleeve 1 and the second protective sleeve 2 need to be fixed. The leaked liquid will slide along the slope of the second protective sleeve 2 towards the second copper sheet 9. When the liquid connects the first copper sheet 8 and the second copper sheet 9 in series, at this time, the first copper sheet 8, the second copper sheet 9, the sound and light alarm 3, the GPS locator 4 and the power supply form a loop, the sound and light alarm 3 alarms, and at the same time the GPS locator 4 operates.
