Description

Technical Field

[0001] The utility model relates to the technical field of pipe network leakage alarm, in particular to a leakage alarm device used for a pipe network. Background Art

[0002] With the acceleration of urbanization and the improvement of people's quality of life, gas, as a clean and efficient energy source, is increasingly used in cities. However, with the increase in the number of gas users, gas leakage accidents also occur frequently, posing a serious threat to people's lives and property safety.

[0003] There are many reasons for gas leakage, some of the common reasons are: forgetting to turn off the gas appliances, resulting in fire and explosion caused by dry pot or overflow of fire source; aging and damage of indoor pipelines causing poisoning and explosion, etc. In addition, there are some uncommon reasons, such as gas pipelines being damaged by external forces and gas equipment failures.

[0004] In the existing technology, the two main methods for gas leak detection are manual inspection and gas alarm. Although the manual inspection method can find some leaks, it is inefficient, easy to miss, and cannot monitor gas leaks in real time. Although the gas alarm can monitor gas leaks in real time, the alarm can usually only detect leaks with higher concentrations, and may not be able to detect some minor leaks in time. In addition, the alarm needs to be regularly maintained and calibrated, otherwise false alarms or missed alarms may occur.

[0005] Therefore, how to improve the accuracy of gas pipeline monitoring and timely detect leakage in the gas pipeline has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of this, the utility model aims at the deficiencies of the prior art and proposes a leakage alarm device for a pipe network, aiming to improve the accuracy of gas pipeline monitoring and timely detect leakage in the gas pipeline.

[0007] In one aspect, the utility model provides a leakage alarm device for a pipe network, comprising:

[0008] A shell, the shell comprising two semicircular shells, the two semicircular shells form a full-circular shell, and the shell is sleeved on the pipe;

[0009] Extension parts, located at two ends of the shell and fixedly connected to the shell;

[0010] A telescopic layer is located inside the shell and is arranged closely to the outer surface of the pipe;

[0011] There are four pressure sensors, which are evenly arranged on the inner surface of the shell in four directions: upper, lower, left and right.

[0012] Furthermore, the extension portion comprises:

[0013] There are four semicircular tubes, and every two of the semicircular tubes form a full-circular tube. The two full-circular tubes are respectively located at two ends of the shell and connected to the shell.

[0014] Furthermore, a buffer layer is provided on the inner surface of each of the semicircular tubes.

[0015] Furthermore, the leakage alarm device for the pipe network further includes:

[0016] A display terminal, connected to the pressure sensor, for real-time monitoring of the pipeline;

[0017] An alarm device is connected to the pressure sensor and is used to give an alarm when the pipeline leaks.

[0018] Furthermore, it also includes:

[0019] A hinge plate is connected to one side of the full-circle shell and is used for fixedly connecting the two semi-circle shells.

[0020] Furthermore, a battery is provided inside the hinged plate, the battery is electrically connected to the pressure sensor, and the battery is used to supply power to the pressure sensor.

[0021] Furthermore, the leakage alarm device for the pipe network further includes:

[0022] The clamping part is located at the other side of the full-circle shell away from the hinge plate. The clamping part includes a bolt locking assembly and is used to clamp the shell.

[0023] Furthermore, the leakage alarm device for the pipe network further includes:

[0024] The protective sleeve is sleeved on the outside of the shell and fixedly connected to the shell.

[0025] Furthermore, a gas sensor is provided on the inner side of the shell and is arranged toward the pipeline.

[0026] Furthermore, a gas-sensitive color-changing layer extending out of the shell is provided between the shell and the pipe.

[0027] Compared with the prior art, the beneficial effect of the utility model is that the shell can effectively protect the pipeline. The shell adopts two semicircular shells to form a full-circular shell, which can be easily mounted on the pipeline and can effectively protect the pipeline from the influence of the external environment. The material of the shell needs to be selected with excellent corrosion resistance, wear resistance and aging resistance, which can ensure that its performance and service life are maintained for a long time. The surface of the shell is provided with multiple observation windows, which can observe the situation inside the pipeline in real time. The design of the extension part ensures that the shell will not loosen or fall off. The telescopic layer can stretch to the surroundings and touch the pressure sensor when the pipeline leaks. Once the pressure sensor is touched, an alarm will be triggered. At the same time, the telescopic layer can also effectively absorb the impact force when the pipeline is subjected to external impact to prevent the pipeline from being damaged. The four pressure sensors can also detect the pressure conditions of the pipeline in four directions at the same time, so as to have a more comprehensive understanding of the pressure conditions of the pipeline and improve the accuracy of pipeline leakage detection.

[0037] See also Figure 1-4 As shown, this embodiment provides a leakage alarm device for a pipe network, comprising:

[0038] The shell 100 includes two semicircular shells, which form a full-circular shell. The shell 100 is sleeved on the pipe 200.

[0039] The extension portions 110 are located at two ends of the housing 100 and are fixedly connected to the housing 100 .

[0040] The expansion layer 120 is located inside the housing 100 and is arranged closely to the outer surface of the pipe 200 .

[0041] There are four pressure sensors 130 , which are evenly arranged on the inner surface of the housing 100 in four directions: top, bottom, left, and right.

[0042] Preferably, the material of the housing 100 needs to be a material with excellent corrosion resistance, wear resistance and aging resistance.

[0043] Preferably, a plurality of observation windows are provided on the surface of the housing 100 for observing the internal conditions of the pipeline 200 .

[0044] It can be seen that the housing 100 is composed of two semicircular housings, which form a full-circular housing and are sleeved on the pipe 200, which helps the stability of the device. The extension part 110 is located at both ends of the housing 100 and is fixedly connected to the housing 100, which helps to ensure that the housing 100 is firmly fixed on the pipe 200. The telescopic layer 120 is located inside the housing 100 and is arranged close to the outer surface of the pipe 200. There are four pressure sensors 130, which are evenly arranged on the inner surface of the housing 100 in the upper, lower, left and right directions. The pressure sensor 130 monitors the pressure changes around the pipe 200.

[0045] It can be understood that the housing 100 can effectively protect the pipeline 200. The housing 100 uses two semicircular housings to form a full-circular housing, which can be easily sleeved on the pipeline 200, and can effectively protect the pipeline 200 from the influence of the external environment; the material of the housing 100 needs to be selected with excellent corrosion resistance, wear resistance and aging resistance, which can ensure that its performance and service life are maintained for a long time; the surface of the housing 100 is provided with multiple observation windows, which can observe the situation inside the pipeline 200 in real time. The design of the extension part 110 ensures that the housing 100 will not loosen or fall off. The telescopic layer 120 can stretch to the surroundings and touch the pressure sensor 130 when the pipeline 200 leaks. Once the pressure sensor 130 is touched, an alarm will be issued; at the same time, the telescopic layer 120 can also effectively absorb the impact force when the pipeline 200 is subjected to external impact, so as to prevent the pipeline 200 from being damaged. The four pressure sensors 130 can also detect the pressure of the pipeline 200 in four directions at the same time, so as to understand the pressure of the pipeline 200 more comprehensively and improve the accuracy of the leakage detection of the pipeline 200.

[0046] Specifically, the extension portion 110 includes:

[0047] There are four semicircular tubes 111 , and every two semicircular tubes 111 form a full-circular tube. The two full-circular tubes are respectively located at two ends of the shell 100 and connected to the shell 100 .

[0048] Specifically, a buffer layer 112 is disposed on the inner surface of each semicircular tube 111 .

[0049] Preferably, the buffer layer 112 is made of rubber material.

[0050] Preferably, every two semicircular tubes 111 are connected by a fixing plate.

[0051] Preferably, a connecting piece 113 is provided on one side of each of the two semicircular tubes 111 away from the fixing plate.

[0052] Further preferably, the connecting member 113 is a screw or a nut.

[0053] It can be seen that there are four semicircular tubes 111, and every two semicircular tubes 111 can form a whole circular tube. The two whole circular tubes are respectively located at the two ends of the housing 100 and are connected to the housing 100. The fixing plate is used to connect the two semicircular tubes 111 together. The connecting piece 113 is a screw or a nut. The two semicircular tubes 111 can be easily connected together by the fixing plate and the connecting piece 113 to form a complete whole circular tube. At the same time, the connecting piece 113 can also be easily disassembled and replaced, so that the entire extension 110 is easier to maintain and repair. The buffer layer 112 is arranged on the inner surface of each semicircular tube 111, which can effectively increase the friction between the semicircular tube 111 and the pipeline 200, and improve the stability of the semicircular tube 111 fixed on the pipeline 200.

[0054] It can be understood that by combining multiple semicircular tubes 111, multiple full-circular tubes can be formed, so that the entire extension portion 110 has better stability and load-bearing capacity; by setting the buffer layer 112, the friction between the semicircular tube 111 and the pipe 200 can be effectively increased, and the stability of the semicircular tube 111 fixed on the pipe 200 can be improved; by setting the connecting piece 113, the two semicircular tubes 111 can be conveniently connected together to form a complete full-circular tube, and it is convenient for maintenance and repair.

[0055] Specifically, the leakage alarm device used in the pipe network also includes:

[0056] The display end is connected to the pressure sensor 130 and is used for real-time monitoring of the pipeline 200 .

[0057] The alarm device is connected to the pressure sensor 130 and is used to give an alarm when the pipeline 200 leaks.

[0058] Preferably, it also includes: a controller; the controller is connected to the pressure sensor 130 and the alarm device, and is used to receive the signal of the pressure sensor 130 and control the alarm action of the alarm device.

[0059] It can be seen that the controller is connected to the pressure sensor 130 and the alarm device, and is used to receive the signal of the pressure sensor 130 and control the alarm action of the alarm device. When the telescopic layer 120 in the housing 100 stretches to the surroundings and touches the pressure sensor 130, the pressure sensor 130 will send a signal to the controller. After receiving the signal, the controller controls the alarm device to emit an alarm sound to remind the staff to check and repair the pipeline 200 in time.

[0060] It can be understood that the controller is connected with the pressure sensor 130 and the alarm device to have functions such as real-time monitoring, remote monitoring and management, which can promptly detect and solve problems such as pipeline 200 leakage and ensure the normal operation of the pipeline 200 system.

[0061] Specifically, the leakage alarm device used in the pipe network also includes:

[0062] The hinge plate 101 is connected to one side of the full-circle shell and is used to fix the two semi-circle shells.

[0063] Specifically, a battery is disposed inside the hinge plate 101 , and the battery is electrically connected to the pressure sensor 130 , and the battery is used to supply power to the pressure sensor 130 .

[0064] See also Figure 2 As shown, in a specific embodiment of the utility model, it also includes:

[0065] The clamping portion 102 is located at the other side of the full-circle shell away from the hinge plate. The clamping portion 102 includes a bolt locking assembly 1021 . The clamping portion 102 is used to clamp the shell 100 .

[0066] It can be seen that the two semicircular shells are connected by the hinge plate 101, which is convenient for sleeve installation on the pipe 200; the hinge plate 101 is provided with a battery inside to power the pressure sensor 130. The clamping part 102 can firmly fix the full-circular shell on the pipe 200.

[0067] It is understandable that, through the design of the hinge plate 101 and the clamping part 102, the two semicircular shells can be conveniently connected to the pipe 200 and can be firmly fixed to the pipe 200. This improves work efficiency, reduces operating difficulty, and enables workers to complete work more conveniently and quickly.

[0068] Specifically, the leakage alarm device used in the pipe network also includes:

[0069] The protective cover is sleeved on the outside of the housing 100 and is fixedly connected to the housing 100 .

[0070] Furthermore, the protective cover is made of a waterproof material to prevent moisture from penetrating into the interior of the housing 100 .

[0071] Specifically, a gas sensor disposed toward the pipe 200 is provided inside the housing 100 .

[0072] Furthermore, the gas sensor is used to detect whether there is a gas leak in the pipeline 200, and transmit the detection result to a controller connected to the gas sensor.

[0073] Specifically, a gas-sensitive color-changing layer extending out of the shell 100 is provided between the shell 100 and the pipe 200 .

[0074] Furthermore, the gas-sensitive color-changing layer is made of a material having a color-changing property, and whether there is a gas leakage in the housing 100 can be determined based on the color change of the gas-sensitive color-changing layer.

[0075] It can be seen that the protective cover protects the entire housing 100 and prevents moisture from penetrating into the housing 100. The gas sensor can be used to detect whether there is gas leakage in the pipeline 200, and transmit the detection result to the controller, which controls the display end and turns on the alarm, providing a more intuitive and convenient detection method for the detection personnel.

[0076] It is understandable that the protective cover has a very obvious protective effect on the entire housing 100. It can effectively prevent moisture from penetrating into the interior of the housing 100, thereby ensuring the integrity and safety of the housing 100. The gas sensor can be used to detect whether there is a gas leak in the pipeline 200, and transmit the detection result to the controller, which then controls the display end to display the detection result in a more intuitive way; when the gas concentration exceeds the set value, the controller will also turn on the alarm to promptly remind the detection personnel to take corresponding measures to ensure safety. The gas-sensitive color-changing layer can more accurately grasp the gas leakage situation by observing the color change; it not only improves the detection efficiency, but also reduces the detection error.

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
