Description

Technical Field

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

[0002] Water supply and drainage pipelines refer to pipeline systems used to transport and distribute water (such as tap water) in water systems, as well as to collect, transport and discharge wastewater, sewage and rainwater. Water supply and drainage pipeline systems usually include two main types of water supply pipelines and drainage pipelines. Water supply pipelines are responsible for transporting tap water and other drinking water, while drainage pipelines are used to discharge sewage, wastewater and rainwater. Water supply and drainage pipeline systems are composed of a variety of pipelines, pipe fittings, pumping stations, reservoirs and other structures, which are essential to maintaining the normal operation of water supply and drainage systems. At present, the thickness of sediment in municipal drainage pipelines is mostly measured by directly inserting a rod into the sediment, and then pulling out the rod to measure the traces of sediment left on the surface of the rod. However, the traces of sediment are easily washed away by the water in the pipeline when they are pulled out, which affects the accuracy of the measurement of the thickness of sediment in municipal drainage pipelines.

[0003] In view of the above technical problems, a device for detecting the thickness of sediment in municipal drainage pipes is disclosed in the announcement number CN211783204U. The staff can directly read the actual value from the arc scale without pulling out the device to measure the sediment traces on the square plug rod, which saves time and effort. The mechanism can improve the accuracy of measuring the thickness of sediment in municipal drainage pipes and improve the efficiency of measuring the thickness of sediment.

[0004] The above patent also has the following shortcomings: when performing depth detection on sediments, it is impossible to locate and lock the height position during the depth measurement process, so that the height position needs to be manually controlled by hand to move up and down. Continuous holding can easily cause loss of strength, or unstable holding can lead to a decrease in detection accuracy. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in 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 in 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.

[0023] The utility model provides a sediment detection device for water supply and drainage pipes, comprising an insertion tube 1, the inner cavity of the insertion tube 1 is provided with a detection mechanism 3 for detecting the depth of sediment, the upper part of one side of the insertion tube 1 is provided with a positioning mechanism 2 for limiting and tightening the detection mechanism 3, the bottom end of the insertion tube 1 is provided with an insertion mechanism 5 for breaking the sediment, the positioning mechanism 2 comprises a connecting tube 21, and the connecting tube 21 is fixedly installed at the upper part of one side of the insertion tube 1;

[0024] The positioning mechanism 2 includes a spring 22, which is welded to one end of the inner cavity of the insertion tube 1. A circular plate 23 is welded to one end of the spring 22. A connecting rod 25 is fixedly installed on one side of the circular plate 23. A clamping plate 26 is fixedly installed on one end of the connecting rod 25. A pull rod 24 is fixedly installed on the other side of the circular plate 23.

[0025] The detection mechanism 3 can be directly and conveniently positioned so that it can be locked after being moved to the desired position without manual support, thus saving time and effort and being easy to operate.

[0026] When the extension rod 31 is pressed against, the elasticity of the spring 22 pushes the circular plate 23, and the circular plate 23 drives the pressing plate 26 to closely contact the fixed plate 32 through the connecting rod 25, and the contact surfaces of the fixed plate 32 and the pressing plate 26 are engraved with anti-slip grooves to improve their protection.

[0027] Preferably, the detection mechanism 3 includes a moving component and a fixed plate 32, the moving component is arranged inside the insertion tube 1, and the fixed plate 32 is arranged on one side of the moving component.

[0028] like Figure 4 As shown, the moving assembly includes an extension rod 31, which is inserted into the insertion tube 1. A measuring plate 33 is fixedly installed at the lower part of the outer side of the extension rod 31 to facilitate its downward movement and insertion connection, so as to be used for depth detection of sediments.

[0029] There are slots 6 on both sides of the insertion tube 1 , and the measuring plate 33 is located inside the slots 6 for sliding. The slots 6 are provided to facilitate the measuring plate 33 to be inserted into the insertion tube 1 .

[0030] In addition, a handle 4 is fixedly installed on the upper part of the other side of the insertion tube 1, and a through-opening is opened on the upper part of one side of the insertion tube 1. The clamping plate 26 is located inside the through-opening. The handle 4 is convenient for hand holding to drive the insertion tube 1 to be inserted into the pipeline to complete the insertion depth detection operation. The opening is convenient for adapting the clamping plate 26.

[0031] Furthermore, the insertion mechanism 5 includes a connecting assembly and a cone head 53. The connecting assembly is arranged at the bottom end of the insertion tube 1, and the cone head 53 is arranged at the bottom of the connecting assembly.

[0032] like Figure 2 As shown, the connecting assembly includes an internal threaded tube 51, which is fixedly installed at the bottom end of the insertion tube 1. The internal thread of the internal threaded tube 51 is connected to an external threaded rod 52, and the bottom end of the external threaded rod 52 is fixed to the cone head 53, which is convenient for directly breaking the sediment and is easy to disassemble and replace. It is simple and convenient to use.

[0033] When replacing:

[0034] As shown in the figure, the installation state is shown. The cone head 53 is rotated counterclockwise to drive the external threaded rod 52 to rotate, so that its thread is separated from the internal threaded tube 51 to complete the disassembly operation. When installing, the cone head 53 is rotated clockwise to drive the external threaded rod 52 to rotate, and the thread extends to the inside of the internal threaded tube 51 to complete the installation operation.

[0035] During testing;

[0036] Pulling the pull rod 24 outwards drives the circular plate 23 to move and compresses the spring 22 until the connecting rod 25 drives the clamping plate 26 to move no further and then stops pulling. Then the extension rod 31 is inserted into the insertion tube 1. When inserting, align the measuring plate 33 with the position of the notch 6 to complete the limited insertion operation to ensure its verticality. When inserting, the compressive tension on the spring 22 can be released. According to the push of the reaction force of the spring 22, the clamping plate 26 is pressed against one side of the fixed plate 32 to be pressed against it, so that the extension rod 31 can be fixed in the pressing position without pressing the extension rod 31 downwards.

[0037] At this time, the handle 4 is held by hand to drive the insertion tube 1 to move downward until it is inserted into the interior of the sediment through the cone head 53, and the cone head 53 is inserted into the pipeline to a state where it cannot go any deeper. At this time, the depth of the sediment is the depth required to be measured. At this time, the extension rod 31 is continuously pushed downward to drive the measuring plate 33 to be located on the surface of the sediment, and then both are directly taken out. At this time, the height between the two, that is, the height between the bottom of the measuring plate 33 and the bottom end of the cone head 53, is the depth of the sediment in the pipeline. It can be measured directly by an external tape measure, or by engraving scale lines on the outside of the insertion tube 1 for measurement. The above components are all standard parts, so it is easy to obtain the required height value.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
