Description

Technical Field

[0001] The invention relates to the technical field of water conservancy equipment testing facilities, and in particular to a pipe network pressure detection device and method. Background Art

[0002] Pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the ambient pressure. It is widely used in almost all industrial processes and scientific research fields. It can be seen everywhere in the fields of thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, etc. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are increasingly widely used because of their elastic sensitive elements with high mechanical strength and convenient production.

[0003] During the use of existing pressure gauges, since the pressure gauges themselves can only measure and have no ability to control water flow, when encountering abnormal or sudden situations, the pressure gauges are easily damaged due to unstable water flow, which in turn increases the cost losses of the enterprise. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art, in order to achieve the goal of detecting long-distance pipelines with a single release, which is suitable for long-distance trunk line detection; accurately identify the broken wire area and estimate the number of broken wires, which is helpful to optimize the PCCP pipeline maintenance plan; it can detect the corrosion of metal pipelines (such as wall thickness loss, pitting corrosion, sheet corrosion, etc.), and provide reliable data support for pipeline finite element analysis (FEA), and provide a pipeline network pressure detection device and method to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a pipeline pressure detection device comprises a pressure gauge, the surface of the pressure gauge is fixedly connected to a connecting head, the surface of the connecting head is provided with a slide groove, the interior of the slide groove is slidably connected with a sliding handle, a water pipe is inserted into the interior of the slide groove, a nut is sleeved on the surface of the slide groove, the surface of the water pipe is provided with a clamping groove, the end of the sliding handle is fixedly connected to a fixing ring, the interior of the fixing ring is clamped with a spring ring, the surface of the spring ring is sleeved with a clamp, the surface of the water pipe is fixedly connected to a connecting piece, the surface of the connecting piece is provided with an eccentric groove, the interior of the eccentric groove is slidably connected with a sliding twist, the end of the sliding twist is fixedly connected with a rotating plate, the surface of the rotating plate is provided with an arc groove, the interior of the arc groove is slidably connected with a fixed block, the surface of the rotating plate is movably connected with a spoke, and the surface of the spoke is movably connected with a hinge.

[0006] As a preferred technical solution of the present invention, the number of the arc grooves is equal to that of the fixed blocks, and the arc grooves are opened at equal intervals on the surface edge of the rotating plate, which maximizes the control ability of the overall device and ensures the practicality of the overall device.

[0007] As a preferred technical solution of the present invention, the number of the spokes is equal to the number of the arc grooves, and the ends of the spokes are installed on the surface edge of the rotating plate and located in the middle of the two arc grooves, which effectively enhances the stability of each component and at the same time enhances the support strength of the overall device.

[0008] As a preferred technical solution of the present invention, the fixed block is slidably connected inside the arc groove, and the end of the fixed block is installed on the inner wall surface of the connecting piece, which better protects the use of the overall device from being affected and enhances the practicality of operating the overall device.

[0009] As a preferred technical solution of the present invention, the number of hinges is equal to the number of spokes, and the ends of the spokes are installed on the upper surfaces of the ends of the hinges, and the hinges are distributed at equal intervals inside the rotating plate, which better enhances the balance of the overall device and effectively enhances the flexibility of use of the overall device.

[0010] As a preferred technical solution of the present invention, the nut and the connector are both installed on the surface of the water pipe. At the same time, the water pipe is slidably connected to the surface of the connector, and the inner wall of the water pipe is provided with a threaded groove that matches the surface of the connector, which further enhances the operability of the overall device and ensures its firmness and stability during use.

[0011] A method for using a pipe network pressure detection device is as follows:

[0012] S1. When using a pressure gauge for measurement, the pressure gauge needs to be connected to the water pipe first. When connecting, the staff first inserts the top of the water pipe into the inside of the connector, then manually slides the nut and rotates it on the surface of the connector to tighten it so that the inner wall thread groove of the nut is engaged and fixed with the spiral pattern on the surface of the connector;

[0013] S2. When the nut is being tightened, the sliding handle is pulled by the friction of the nut and slides inside the slide slot, driving the fixed ring to rotate. Since a spring ring is installed inside the fixed ring, when the fixed ring is pulled and rotated, the spring ring is driven to close inward, and the clamp installed on the surface of the spring ring is pulled and closed inward, so that the end of the clamp is clamped inside the surface of the clamping slot;

[0014] S3. The water valve can then be manually started. In order to avoid accidents during use that may cause uncontrollable water flow and damage to the pressure gauge, when the water flow needs to be cut off, the staff can manually turn the slider again. The displacement of the slider drives the rotating plate to rotate inside the connecting piece. When the rotating plate rotates, the spokes are driven to shift, and then the hinges are driven to open and close, thereby controlling the water flow inside the water pipe and protecting the pressure gauge.

[0015] The present invention has the following beneficial effects:

[0016] 1. The pipe network pressure detection device and method drives the sliding handle to deflect by the nut, and the sliding handle rotates to drive the fixed ring to rotate, and then the rotation of the fixed ring drives the spring ring to close to drive the clamp to close, thereby achieving the effect of strengthening the firmness of the water pipe and the connector, and further improving the stability of the water pipe connection;

[0017] 2. The pipeline pressure detection device and method moves inside the eccentric groove by sliding and twisting. The sliding and twisting movement drives the rotating plate to rotate, and then the rotation of the rotating plate drives the spokes to deflect to control the opening and closing of the hinge, thereby achieving flexible control of the water flow in the water pipe and enhancing the strain performance of the pressure gauge when encountering abnormal situations during operation.
