Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and in particular to a water supply pipeline pressure detection device. Background Art

[0002] Water supply pipelines are pipe systems used to transport water from water sources to homes, businesses, public places, etc. The main function of the water supply pipeline system is to provide domestic water, fire water, industrial water, etc. These pipes may be buried underground to form a water supply network to effectively deliver water to various demand points. There are many ways to classify water supply pipelines, including metal pipes and plastic pipes. In addition, according to the layout form, the water supply network can be divided into tree-shaped pipe networks, ring-shaped pipe networks, and mixed pipe networks. According to function, water supply pipelines can be divided into water transmission pipes and water distribution pipes, and the water supply pipeline pressure detection device is a device used to monitor and measure pressure changes in the water supply pipeline system.

[0003] Existing water supply pipeline pressure detection devices are mainly used to monitor the pressure of pipelines in use so as to detect pipeline leaks or other problems in time. However, in some cases, there may be slight cracks or leaks in the pipeline. Such problems may not be easy to detect at the beginning and may gradually worsen. Therefore, relying solely on the pressure detection device in use may not be able to detect these potential problems at the source. In order to more effectively solve these potential water seepage problems, a water supply pipeline pressure detection device is particularly needed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 The utility model provides a technical solution for a water supply pipeline pressure detection device: a water supply pipeline pressure detection device, comprising a detection platform 1 and a right fixed plate 2 and a left fixed plate 3 relatively arranged on the top of the detection platform 1, a groove 7 is provided on the opposite sides of the right fixed plate 2 and the left fixed plate 3, and a sealing ring 71 is fixedly installed on the inner wall of the groove 7, when the end face of the pipeline is placed in the groove 7 and tightly attached to the sealing ring 71, a sealed space can be formed in the inner cavity of the pipeline, which can further improve the accuracy of the pipeline during pressure detection;

[0022] Specifically, a retaining assembly 4 is provided on the left side of the inspection platform 1 to drive the right fixed plate 2 and the left fixed plate 3 to synchronously displace to seal and position the two ends of the pipeline. The retaining assembly 4 includes a turning handle 41. The inner wall of the turning handle 41 is fixedly connected with a bidirectional threaded screw 42. The outer wall of the bidirectional threaded screw 42 is threadedly connected with two displacement blocks 43. The right fixed plate 2 and the left fixed plate 3 are respectively fixedly connected to the top of the two displacement blocks 43. The turning handle 41 drives the bidirectional threaded screw 42 to rotate so that the two displacement blocks 43 are relatively displaced on the outer wall threads of the bidirectional threaded screw 42 until the right fixed plate 2 and the left fixed plate 3 respectively position the two ends of the pipeline to achieve the fixation of the pipeline.

[0023] The top of the test bench 1 is fixedly connected with a mounting frame 51, and a barometer 5 is fixedly installed on the top of the mounting frame 51. The barometer 5 is used to measure gas pressure. The working principle of the barometer 5 can be simply described as external pressure acting on a spring to deform it, thereby causing a certain component (such as a pointer) in the measuring device to move, and finally displaying the magnitude of the pressure;

[0024] refer to Figure 1-Figure 4As shown, in order to detect the pressure in the pipeline, the following settings are made: a pressure-applying assembly 6 for detecting the pressure in the pipeline is arranged on the top of the right end of the detection platform 1, and the pressure-applying assembly 6 includes a motor 61, and the motor 61 is fixed to the inner wall of the detection platform 1, and the output end of the motor 61 is fixedly connected to a driving plate 62, and the end of the driving plate 62 away from the output end of the motor 61 is movably connected to a linkage plate 63, and the end of the linkage plate 63 away from the driving plate 62 is movably connected to a reciprocating rod 64, and an air supply cylinder 65 is arranged on the top of the detection platform 1, and the outer wall of the air supply cylinder 65 is fixedly connected to a support rod 651 fixedly connected to the top of the detection platform 1, and the inner wall of the air supply cylinder 65 is sleeved with a piston 66, and the inner wall of the air supply cylinder 65 is fixedly connected to a piston 66 The limiting shift ring 67 and the piston 66 are fixed to the end of the reciprocating rod 64 away from the linkage plate 63. The top of the air supply cylinder 65 away from the linkage plate 63 is fixedly connected with an air intake pipe 68. The inner wall of the air intake pipe 68 is fixedly installed with a filter screen 69 by a buckle. The setting of the filter screen 69 can prevent foreign debris from entering the air supply cylinder 65. The top of the air supply cylinder 65 away from the linkage plate 63 is fixedly connected with an air flow pipe 610. A one-way valve is installed inside the air supply pipe 68 and the air flow pipe 610. When the air supply pipe 68 is opened, the air flow pipe 610 is closed. Conversely, when the air supply pipe 68 is closed, the air flow pipe 610 is opened. The working principle of the one-way valve can be attributed to the use of air pressure and the structural design inside the valve to achieve a flow in one direction. The effect of allowing gas to flow in the other direction and preventing gas flow in the other direction is that the end of the gas flow pipe 610 away from the gas supply cylinder 65 is fixedly connected with a hose 1 611, and the end of the hose 1 611 away from the gas flow pipe 610 is fixedly connected with a connecting pipe 1 614, and the connecting pipe 1 614 is connected to the right fixed plate 2, and the side of the left fixed plate 3 away from the right fixed plate 2 is fixedly connected with a connecting pipe 2 6141, and the end of the connecting pipe 2 6141 away from the left fixed plate 3 is fixedly connected with a hose 2 612, and the end of the hose 2 612 away from the connecting pipe 2 6141 is fixedly connected with an arc tube 613, and the end of the arc tube 613 away from the hose 2 612 is connected to the barometer 5. The motor 61 is started to drive the output end to drive the driving plate 62 to rotate, and the driving plate 6 2 The rotating linkage plate 63 pushes the reciprocating rod 64 to move left and right. When the reciprocating rod 64 drives the piston 66 to move right, the outside air enters the air delivery cylinder 65 from the air inlet pipe 68. At this time, the air flow pipe 610 is closed. When the reciprocating rod 64 drives the piston 66 to move left, the air inlet pipe 68 is closed, and the outside air enters the hose 1 611-connecting pipe 1 614-pipeline cavity-connecting pipe 2 6141-hose 2 612-arc pipe 613-pressure gauge 5 in sequence through the air flow pipe 610. When the pressure gauge 5 is performing a pressure test, if there is a leak in the pipeline, the pressure will drop after pressurization, so that the leak can be found in time. In this way, the leak can be repaired before construction begins to ensure the normal operation and safety of the water supply system.

[0025] The working principle and use process of the utility model are as follows: after placing the pipeline between the right fixed plate 2 and the left fixed plate 3, the handle 41 is rotated to make the right fixed plate 2 and the left fixed plate 3 relatively displaced, until the two ends of the pipeline are respectively placed in the groove 7 and tightly attached to the sealing ring 71, a sealed space can be formed in the inner cavity of the pipeline, and the motor 61 is started to make the reciprocating rod 64 displace left and right. When the reciprocating rod 64 drives the piston 66 to move right, the outside gas enters the air delivery cylinder 65 from the air inlet pipe 68. When the reciprocating rod 64 drives the piston 66 to move left, the outside gas enters the inner cavity of the pipeline through the air flow pipe 610. When the barometer 5 performs a pressure test on the pipeline, if there is a leak in the pipeline, pressurization will cause a pressure drop, because the leak will cause gas to leak from the pipeline, reducing the total amount of gas in the pipeline and thus reducing the pressure. When pressure is applied, the barometer 5 can monitor the pressure change in the pipeline. If the pressure drop exceeds expectations, it means that there is a leak.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
