Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline detection, and particularly relates to a pipeline detection device. Background Art

[0002] Water is the source of life, and people cannot live without water resources in their daily lives. Urban water supply refers to the drinking water source that is treated and transported through pipelines to every household in the city for residents to use. In order to ensure the safety of residents' daily water use and water sources, the water sources in the transmission pipelines need to be tested regularly.

[0003] Currently, a sampling port is typically installed on the delivery pipeline, which is then sealed with bolts. These bolts are then removed during inspection to allow the water in the delivery pipeline to escape. However, this method requires frequent removal and installation of the bolts, which can easily wear out over time and cause leakage in the delivery pipeline, resulting in unnecessary waste. Furthermore, leakage in the delivery pipeline can reduce pipeline pressure, causing unnecessary trouble for users.

[0004] Therefore, in order to solve the above technical problems, it is necessary to provide a pipeline detection device.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a pipeline detection device, which can solve the problem in the prior art that the detection of water flow in the pipeline easily causes leakage of the transmission pipeline.

[0007] In order to achieve the above-mentioned objective, a specific embodiment of the present invention provides a pipeline detection device.

[0009] A flow expansion pipe is installed on the delivery pipeline;

[0010] The pressurizing mechanism is installed in the conveying pipeline, and the pressurizing mechanism includes a fixed support slide rail, a plurality of fixed support shafts are fixed on the fixed support slide rail, and the plurality of fixed support shafts are rotatably connected to a twisting shielding wall plate, and a fixed protective frame is fixedly connected to one side of the fixed support slide rail;

[0011] The collecting mechanism is installed on the conveying pipeline, and the collecting mechanism includes a collecting pipe, and a pressure relief valve is installed in the collecting pipe.

The rotating winding wheel is fixed on the rotating drive shaft to avoid the rotating winding wheel from falling off, thereby ensuring the stability of the device.

[0014] In one or more embodiments of the present invention, a fixed bearing is fixedly connected between the rotating drive shaft and the fixed protective frame and the diffuser tube, so that the rotation of the rotating drive shaft is not easily affected and the rotating drive shaft is not prone to shaking or skewing, thereby being able to stably drive the rotating winding wheel to rotate.

[0015] In one or more embodiments of the present invention, a support slider is slidingly provided in the fixed support rail, which is used to support multiple pushing columns and has the function of driving the pushing columns to slide. Multiple evenly distributed pushing columns are installed on the support slider, which are used to push the twisting shielding wall panels, so that the multiple twisting shielding wall panels can be stretched out, and then the twisting shielding wall panels can block the water flow, so that the pressure of the water flow can be increased, providing conditions for the discharge of the water flow.

[0016] In one or more embodiments of the present invention, an elastic connecting rope is fixedly connected between the end of the fixed support slide rail away from the fixed protection frame and the multiple twist shielding wall panels, which is used to pull the twist shielding wall panels to reset.

DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0032] like Figure 1-Figure 5 As shown, a pipeline detection device in one embodiment of the present invention includes: a conveying pipeline 1, a pressurizing mechanism 2 and a collecting mechanism 3.

[0033] like Figure 1-Figure 3 As shown, a flow expansion pipe 101 is installed on the delivery pipe 1 to increase the area through which water flows, thereby offsetting the water flow area occupied by the pressurizing mechanism 2, thereby making the water flow pressure in the delivery pipe 1 and the flow expansion pipe 101 the same.

[0034] like Figure 1-Figure 2 As shown, the pressure mechanism 2 is installed in the conveying pipeline 1 and includes a fixed support rail 201, which is used to provide a track for the sliding of the support slider 207, so that the support slider 207 is not easily deflected. A plurality of fixed support shafts 202 are fixed to the fixed support rail 201, which are used to support the twisting shielding wall plate 203, preventing the twisting shielding wall plate 203 from falling off while allowing the twisting shielding wall plate 203 to rotate freely.

[0035] like Figure 1-Figure 5 As shown, multiple fixed support shafts 202 are rotatably connected to twisted shielding wall plates 203 for blocking the water flow, thereby increasing the water flow pressure in the expansion pipe 101, and then facilitating the water flow to be ejected from the pressure relief valve 302. A fixed protective frame 204 is fixedly connected to one side of the fixed support slide rail 201 for providing space for the rotation of the rotating winding wheel 205 to reduce the influence of the water flow.

[0036] like Figure 1-Figure 2As shown, a rotating winding wheel 205 is installed within the fixed protective frame 204, which is used to wind a traction rope 206, thereby enabling the traction rope 206 to pull the support slider 207 to slide, providing conditions for extending the multiple twist-type shielding wall panels 203. A rotating drive shaft 210 is inserted into the diffuser tube 101, which is used to fix and support the rotating winding wheel 205 and has the function of driving the rotating winding wheel 205 to rotate, allowing the rotating winding wheel 205 to wind the traction rope 206, thereby providing support and transmission for the rotating drive shaft 210. The rotating winding wheel 205 is fixed to the rotating drive shaft 210 to prevent the rotating winding wheel 205 from falling off and ensure the stability of the device.

[0037] Among them, a fixed bearing 212 is fixedly connected between the rotating drive shaft 210 and the fixed protection frame 204 and the diffuser tube 101, so that the rotation of the rotating drive shaft 210 is not easily affected, and the rotating drive shaft 210 is not prone to shaking and tilting, thereby being able to stably drive the rotating winding wheel 205 to rotate.

[0038] like Figure 1-Figure 5 As shown, a support slider 207 is slidably provided within the fixed support rail 201 for supporting and sliding a plurality of push rods 208. The support slider 207 is provided with a plurality of evenly distributed push rods 208 for pushing the twisting shielding panels 203, thereby allowing the plurality of twisting shielding panels 203 to unfold, thereby enabling the twisting shielding panels 203 to block the water flow, thereby increasing the pressure of the water flow and providing conditions for the water flow to be discharged.

[0039] Specifically, an elastic connecting rope 209 is fixedly connected between the end of the fixed support rail 201 away from the fixed protection frame 204 and the multiple twist shielding wall panels 203, which is used to pull the twist shielding wall panels 203 to reset. When the support slider 207 uses water flow to reset, it will no longer push the twist shielding wall panels 203. At this time, the twist shielding wall panels 203 can be reset by the thrust of the water flow and the tension of the elastic connecting rope 209.

[0040] like Figure 1-Figure 5 As shown, a traction rope 206 is fixedly connected between the rotating winding wheel 205 and the support slider 207, which is used to pull the support slider 207 to slide, thereby driving the multiple pushing rods 208 to move through the support slider 207, thereby pushing the twisting shielding wall panel 203. The end of the rotating drive shaft 210 away from the fixed protection frame 204 is fixedly connected to a winding motor 211. The winding motor 211 is installed outside the flow expansion pipe 101 and is used to drive the rotating drive shaft 210 to rotate, providing power for collecting water flow.

[0041] The fixed protection frame 204 is fixedly connected to the inner wall of the flow diffuser 101 by a first fixing post 213, which is used to support the fixed protection frame 204 and prevent it from tilting or shaking. A plurality of second fixing posts 214 are fixedly connected between the fixed support rail 201 and the inner wall of the flow diffuser 101, which are used to support the fixed support rail 201 and prevent it from tilting or shaking.

[0042] like Figure 1-Figure 3 As shown, the collecting mechanism 3 is installed on the conveying pipeline 1. The collecting mechanism 3 includes a collecting pipe 301 for discharging water outward. A pressure relief valve 302 is installed in the collecting pipe 301. The pressure relief pressure value set by the pressure relief valve 302 is slightly greater than the water pressure in the expansion pipe 101. Therefore, when the shielding wall panel 203 is twisted and stretched to block the water flow, the water flow can be quickly ejected from the pressure relief valve 302.

[0043] In addition, one end of the collecting pipe 301 away from the diffuser pipe 101 is threadedly connected to a sealing plug 303 for sealing one end of the pressure relief valve 302 to prevent dust from entering when not in use, thereby reducing the probability of blockage.

[0044] When testing is required, the sealing plug 303 is first removed by rotation, and then one end of the pressure relief valve 302 is connected to the testing equipment. Then, the winding motor 211 is started, and the winding motor 211 drives the rotating drive shaft 210 to rotate, and then drives the rotating winding wheel 205 to rotate, thereby pulling the traction rope 206 to wind and tighten;

[0045] The support slider 207 can be pulled by the traction rope 206, thereby causing the support slider 207 to gradually move toward the side of the fixed protection frame 204, and the movement of the fixed protection frame 204 can drive the multiple pushing columns 208 to slide, so that the pushing columns 208 can push the twist shielding wall plate 203 to rotate, thereby causing the multiple pushing columns 208 to stretch out, achieving the effect of blocking the water flow. At this time, due to the reduction in area, the water flow pressure increases. When the twist shielding wall plate 203 can no longer rotate, the water flow pressure will be greater than the set value of the pressure relief valve 302, thereby causing the water flow to be discharged from the collection pipe 301, and then the water flow will enter the detection equipment to achieve the water quality detection;

[0046] After the detection is completed, it is only necessary to control the rotation drive shaft 210 to reverse by winding the motor 211 so that the twist shielding wall plate 203 can be reset. At this time, the water flow pressure will decrease. When the water flow pressure is less than the set value of the pressure relief valve 302, the water flow will no longer be discharged from the collection pipe 301.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0048] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
