Description

Technical Field

[0001] This application relates to the field of liquid level measurement technology, and more specifically, to a pipeline liquid level gauge. Background Technology

[0002] A pipeline network is a fluid transport network composed of various types of pipes, responsible for water supply, drainage, or sewage discharge. Key nodes in a pipeline network include pipe bends, diameter changes, slope changes, and branch pipe junctions. These nodes are usually equipped with underground structures such as manholes. The core function of manholes is to connect pipelines and provide access for maintenance personnel to operate in the manholes. They also serve to vent air from the pipelines and settle impurities.

[0003] In related technologies, water levels in pipe networks can rise rapidly due to rainfall or blockages. To monitor water levels in manholes in real time, level gauges are typically installed within the manhole shaft. The probe of the level gauge is suspended above the pipes inside the manhole, with its sensor directly contacting the fluid. This allows for long-term recording of changes in the pipe network's water level and provides a basis for network upgrades and renovations.

[0004] In actual installation, workers need to carry drilling equipment down into the well and pre-drill holes in the inner wall of the manhole. Then, the bracket is fixed to the inner wall of the manhole with bolts, and finally, the level gauge is installed and fixed to the bracket. However, this installation method is not only labor-intensive and inefficient, but it also damages the integrity of the manhole wall. Long-term use can easily lead to cracks and water seepage in the manhole wall, thus affecting the structural stability of the manhole. Summary of the Invention

[0005] In view of this, this application provides a pipeline level gauge to solve the problem that drilling and bolting level gauges in related technologies can easily damage the structural integrity of manholes.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A pipeline level gauge includes: a mounting base plate, multiple support arms, a well wall fitting component, an elastic drive assembly, and a level gauge body.

[0008] The mounting base plate has a mounting hole in the middle along the thickness direction, and the level gauge body is fixedly assembled in the mounting hole.

[0009] Multiple support arms are evenly distributed around the circumference of the mounting base plate, and one end of each support arm is fixedly connected to the outer edge of the mounting base plate, while the other end extends away from the mounting base plate.

[0010] The well wall bonding plate assembly corresponds one-to-one with the support arm, and is slidably assembled at the end of the support arm away from the mounting base plate, and is used to abut against the inner wall of the manhole.

[0011] The elastic drive component is disposed between the support arm and the well wall bonding plate assembly, and is used to provide an elastic force that causes the well wall bonding plate assembly to move toward the inner wall of the manhole, so as to achieve self-adaptive installation without drilling.

[0012] In some possible implementations, each of the support arms is fixedly provided with a fixed side plate at the end away from the mounting base plate, and the well wall bonding plate assembly includes a movable side plate and a well wall bonding plate;

[0013] The fixed side plate has two vertically extending first sliding holes symmetrically formed along the thickness direction, and the movable side plate has two second sliding holes symmetrically formed along the thickness direction that correspond to and fit the first sliding holes. The first sliding holes and the second sliding holes are detachably connected by fastening bolts to adjust the relative position of the movable side plate and the fixed side plate.

[0014] In some possible implementations, the top of each of the well wall bonding plates extends outward to form an overlapping plate, the length direction of which is perpendicular to the surface of the well wall bonding plate, for overlapping and supporting the top of the manhole ring.

[0015] In some possible implementations, a sliding plate is vertically provided on the side of the well wall fitting plate near the movable side plate, and the sliding plate slides through the second sliding hole, with the sliding plate and the sliding hole having a clearance fit.

[0016] In some possible implementations, the elastic drive assembly is a return spring, and spring limiting bolts are provided on the opposite sides of the movable side plate and the well wall bonding plate, with the two ends of the elastic drive assembly respectively sleeved on the corresponding spring limiting bolts.

[0017] In some possible implementations, a wedge-shaped abutment block is provided at the bottom of the manhole wall bonding plate. The top width of the wedge-shaped abutment block is greater than its bottom width, and its thickness is less than the length of the bonding plate. The wedge-shaped surface of the wedge-shaped abutment block is adapted to abut against the inner wall of the manhole.

[0018] In some possible implementations, a protective component is also included, which comprises a sealing cover and a waterproof connector;

[0019] The sealing cover is fixed on the side of the mounting base away from the support arm, the detection end of the level gauge body extends out of the sealing cover, and the edge of the sealing cover is provided with a waterproof sealing ring.

[0020] The waterproof connector is fixed to the side wall of the sealing cover and is used for the cable of the level gauge body to pass through.

[0021] The pipeline level gauge provided in this application has at least the following beneficial effects:

[0022] In the pipeline level gauge provided in this application embodiment, multiple support arms are fixedly connected to the outer edge of the mounting base plate. A well wall bonding plate assembly is provided at the end of each support arm away from the mounting clamp. An elastic drive assembly is also provided between the well wall bonding plate assembly and the support arms. The elastic force provided by the elastic drive assembly allows the well wall bonding plate assembly to adaptively abut against the inner wall of the manhole without drilling or forceful expansion. Furthermore, the elastic sliding assembly structure between the well wall bonding plate assembly and the support arms, achieved through the elastic drive assembly, can adapt to and cover existing mainstream manhole specifications, ensuring installation in various manhole sizes. This structural design not only improves the installation efficiency of the level gauge but also avoids damage to the manhole wall structure, thereby extending the service life of the manhole.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figures 1-4 As shown in the embodiment of this application, the pipeline level gauge includes a mounting base 100, multiple support arms 200, a well wall bonding plate 300 assembly, and an elastic drive assembly 400. The mounting base 100 is the supporting structure for the level gauge body 120. The mounting base 100 is responsible for supporting the level gauge body 120 and for fixing it to the inner wall of the manhole to measure the water level in real time. Specifically, the mounting base 100 can be a square plate structure made of 304 stainless steel, with a circular mounting hole 110 pre-drilled in its central area along the thickness direction. A rubber anti-slip ring is provided on the inner wall of the mounting hole 110 for bonding and fixing the level gauge body 120.

[0041] Multiple horizontally extending support arms 200 are integrally formed at several outer edge faces of the mounting substrate 100. The upper and lower surfaces of each support arm 200 are parallel to the mounting substrate 100 and have equal thickness. A fixing side plate 210 is fixedly provided at the end of each support arm 200 away from the mounting substrate 100, and the fixing side plate 210 is perpendicular to the support arm 200. Preferably, the support arms 200 are also made of 304 stainless steel, and are evenly distributed circumferentially along the mounting substrate 100, with equal included angles between adjacent support arms 200.

[0042] In this embodiment, the well wall bonding plate 300 assembly and the support arm 200 are in a one-to-one correspondence. The well wall bonding plate 300 assembly and the support arm 200 are slidably assembled at the end away from the mounting base plate 100, which is used to abut against the inner wall of the manhole. Specifically, each of the multiple support arms 200 has a fixed side plate 210 vertically welded to the end away from the mounting base plate 100. The well wall bonding plate 300 assembly includes a movable side plate 500 and a well wall bonding plate 300. The fixed side plate 210 has two symmetrically distributed vertical first sliding holes 211 along the thickness direction. The first sliding holes 211 have an oblong hole structure. Similarly, the movable side plate 500 has two symmetrically distributed vertical second sliding holes 510 along the thickness direction. The second sliding holes 510 are the same size and aligned with the first sliding holes 211. The two are fixedly connected by fastening bolts 900. Furthermore, by adjusting the position of the fastening bolt 900 within the first sliding hole 211 and the second sliding hole 510, the relative position of the movable side plate 500 and the fixed side plate 210 can be adjusted.

[0043] Continue as Figure 3 and Figure 4 As shown, symmetrically distributed sliding plates 700 are fixedly installed on the side of the manhole wall bonding plate 300 near the movable side plate 500. The sliding plates 700 are inserted into the second sliding hole 510, and the two are clearance-fitted to ensure smooth sliding without radial wobble. Preferably, a buffer anti-slip layer can be bonded to the end of the manhole wall bonding plate 300 away from the movable side plate 500, and its surface is provided with diamond-shaped anti-slip texture to enhance the friction with the manhole wall.

[0044] The elastic drive assembly 400 can be a return spring. Spring limiting bolts 800 are fixed to the opposite sides of the movable side plate 500 and the well wall contact plate 300. The two ends of the return spring are respectively sleeved on the corresponding spring limiting bolts 800. Furthermore, a gap of 1mm to 2mm can be reserved between the two ends of the return spring and the head of the spring limiting bolt 800 to prevent jamming when the return spring is compressed.

[0045] In this embodiment, an overlapping plate 600 extends outward from the top of the manhole wall bonding plate 300, and an anti-slip pad may be provided on the upper surface of the overlapping plate 600. The overlapping plate 600 is used to overlap the top of the manhole opening ring to prevent it from sliding into the manhole. In addition, a wedge-shaped abutment block 1000 is integrally formed at the bottom of the manhole wall bonding plate 300. The top width of the wedge-shaped abutment block 1000 is greater than its bottom width, and its thickness is less than the length of the overlapping plate 600. The wedge-shaped surface of the wedge-shaped abutment block 1000 is adapted to abut against the inner wall of the manhole.

[0046] Preferably, the system further includes a protective assembly, which comprises a sealing cover and a waterproof connector. The sealing cover is fixed to the side of the mounting base 100 opposite to the support arm 200, and the detection end of the level gauge body 120 extends out of the sealing cover. A waterproof sealing ring is provided on the edge of the sealing cover. The waterproof connector is fixed to the side wall of the sealing cover and is used for the cable of the level gauge body 120 to pass through.

[0047] The following is combined with Figures 1-4 The working principle and installation process of the pipeline level gauge provided in the embodiments of this application are described.

[0048] Working principle:

[0049] The core working principle of this application embodiment is a non-drilling installation technology based on elastic adaptive clamping and multiple positioning limits. The elastic drive component 400 provides a continuous and uniform elastic force, driving the well wall fitting component to form a tight contact with the inner wall of the manhole, achieving stable installation of the level gauge body 120 without damaging the well wall structure. Simultaneously, the adjustment structure using the first sliding hole 211 and the second sliding hole 510 adapts to manholes of different diameters, and the dual positioning of the overlapping plate 600 and the wedge-shaped abutment block 1000 ensures accurate positioning of the level gauge body 120 after installation and prevents it from easily loosening.

[0050] During installation, the return spring of the elastic drive assembly 400 is compressed, generating an elastic thrust towards the well wall. This ensures that the buffer anti-slip layer of the well wall bonding plate 300 adheres tightly to the inner wall of the manhole, achieving initial fixation through friction. The overlapping plate 600 overlaps the top of the wellhead ring, limiting the vertical displacement of the level gauge body 120 and preventing sinking due to gravity. The inclined surface of the wedge-shaped abutment block 1000 abuts against the lower part of the inner wall of the manhole, creating a counter-supporting force to resist lateral swaying of the level gauge body 120.

[0051] The sliding hole adjustment structure of the fixed side plate 210 and the movable side plate 500 can adjust the position of the movable side plate 500 by loosening the fastening bolt 900, thereby changing the distance between the well wall bonding plate 300 and the mounting base plate 100, so as to adapt to manholes of different diameters.

[0052] Installation process:

[0053] Workers arrived at the manhole site with the debugged equipment. After opening the manhole cover, they cleared debris and water from the top of the manhole ring to ensure the overlapping plates 600 could be stably connected. With the level gauge body 120 facing down, they held the mounting base plate 100 and placed the equipment into the manhole, allowing the overlapping plates 600 of the three support arms 200 to overlap the top of the manhole ring, thus initially positioning the equipment.

[0054] Apply gentle downward pressure to the mounting base plate 100 so that the well wall bonding plate 300 contacts the inner wall of the manhole. Continue applying pressure until the inclined surface of the wedge-shaped abutment block 1000 abuts against the lower part of the inner wall of the manhole. At this point, the elastic drive assembly 400 is compressed and simultaneously generates a continuous elastic thrust to push the well wall bonding plate 300 tightly against the well wall, thereby achieving lateral fixation. Continue tightening the fastening bolts 900 to lock the position of the movable side plate 500, finally completing the installation and fixation of the level gauge body 120.

[0055] In the pipeline level gauge provided in this application embodiment, multiple support arms 200 are fixedly connected to the outer edge of the mounting base plate 100. A well wall bonding plate 300 assembly is provided at the end of each support arm 200 away from the mounting clamp. An elastic drive assembly 400 is also provided between the well wall bonding plate 300 assembly and the support arm 200. Through the elastic force provided by the elastic drive assembly 400, the well wall bonding plate 300 assembly can adaptively abut against the inner wall of the manhole without drilling or forceful expansion. Furthermore, the elastic sliding assembly structure between the well wall bonding plate 300 assembly and the support arm 200, achieved through the elastic drive assembly 400, can adapt to and cover existing mainstream manhole specifications, ensuring its installation in various manholes of different sizes. This structural design not only improves the installation efficiency of the level gauge but also avoids damage to the manhole wall structure, thereby extending the service life of the manhole.
