Description

Technical Field

[0001] The invention belongs to the field of on-site sampling pipeline space area division of water supply pipelines, and more specifically, relates to an on-site fixed-point division device for water supply pipelines of multiple sizes. Background Art

[0002] The water flow in the water supply pipe belongs to full pipe flow. Outdoor municipal pipes are mostly placed horizontally. The suspended solids, loose sediments and biofilm on the pipe wall are affected by gravity. The microbial attachments and scale corrosion products formed at the bottom and top of the pipe show spatial differences. In recent years, many scholars have made spatial partitions for pipelines and studied various pollutants in each partition.

[0003] In order to explore the pollutants in water supply pipelines, scholars often conduct on-site sampling of outdoor municipal water supply pipelines, etc., to qualitatively partition the pipelines and confirm the spatial fixed points. After the surface covering of the pipeline is dug out, the zoning and positioning work is often not carried out in time due to construction restrictions. For example, the pipeline is often rotated due to the unloading and installation of the two fixed parts of the pipeline; or due to the continuity of construction, the pipeline zoning work needs to be carried out after the pipe section is lifted to the ground by machinery. As a result, there is a deviation in the confirmation and division of the pipeline space fixed points, which leads to inaccurate extraction of pollutants in the pipeline.

[0004] At present, some domestic scholars often carry out pipeline zoning by lifting the pipe section to the ground or pulling it to the laboratory, and then do subsequent work such as positioning the pipe section and zoning it by winding steel wire. Therefore, these methods often cause problems such as unreasonable pipe section zoning and uncompensated deviation. Summary of the invention

[0005] In view of the shortcomings of the prior art and the limitations of the construction site, the present invention proposes a device for dividing the space inside a pipe at fixed points on site for water supply pipes of multiple sizes. The device is simple, fast, time-saving and efficient to operate during the zoning process, and can be assembled and partitioned on site according to pipe sections of different diameters.

[0011] The vertical pendulum has a cycloid at the upper end and a pendulum at the lower end.

[0012] The water supply pipe wall clamp is composed of two clamping pieces, namely, a water supply pipe outer wall clamp and a water supply pipe inner wall clamp. The size of the water supply pipe inner wall clamp is smaller than that of the water supply pipe outer wall clamp.

[0013] Angle fine-adjusters with slide grooves are arranged on both left and right sides of the bottom of the leveling plate, and the angle fine-adjusters are stainless steel knobs with threads.

[0014] The leveling plate is hard and has no bending, and is assembled by splicing, and is spliced ​​on site according to the size of the water supply pipe; the upper surface of the leveling plate is provided with a groove for fixing the right-angle vertical frame, and the leveling plate is provided with a slide, and the slide is divided into an inner slide and an outer slide, the inner slide is for the horizontal point-finding splint of the pipeline to slide left and right, and the outer slide is for the angle fine-tuner to slide.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 6 As shown, the present invention is suitable for a device for dividing the space inside a water supply pipe of various sizes on site at a fixed point, and includes a vertical pendulum 3, a water supply pipe wall clamp, a right-angle vertical frame 4, a leveling plate 5, and a pipeline transverse point-finding clamp 6.

[0034] The vertical pendulum 3 has a cycloid 11 at the upper end and a pendulum 12 at the lower end. The water supply pipe wall clamp is composed of two clamping pieces, namely, a water supply pipe outer wall clamp 1 and a water supply pipe inner wall clamp 2. However, since the inner and outer diameters of the water supply pipe are inconsistent, the size of the water supply pipe inner wall clamp 2 is smaller than that of the water supply pipe outer wall clamp 1. The water supply pipe wall clamp can be adjusted and replaced according to the thickness and size of the pipe wall.

[0035] The right-angle vertical frame 4 is arranged in the middle of the upper surface of the leveling plate 5, and the pipeline transverse point-finding clamps 6 are respectively arranged on the left and right sides of the upper surface of the leveling plate 5, and the pipeline transverse point-finding clamps 6 on both sides can slide left and right above the leveling plate 5 and clamp the water supply pipe.

[0036] The leveling plate 5 is made of hard plastic or stainless steel, which can adapt to the corrosion caused by long-term contact with water, soil, and chemical agents, as well as internal and external pressure. An angle fine-tuner 16 with a slide groove is set on both sides of the bottom of the leveling plate 5. The angle fine-tuner 16 is a stainless steel knob with a thread, which has a certain corrosion resistance to chemical reagents, soil, water, etc. The angle fine-tuner 16 is buckled into its slide groove from the outer end of the leveling plate 5, and can move left and right, or be fixed in the position of the leveling plate 5 by a nut, or the horizontal position of the leveling plate 5 can be fine-tuned by its own lifting shaft. The leveling plate 5 is hard and has no bending. It adopts a splicing assembly method. Each section is 30cm. The upper surface of the middle section is provided with a groove and a slideway for fixing the right-angle vertical frame 4. The remaining sections are only provided with slideways, and the slideways are divided into inner slideways and outer slideways. The inner slideway is for the pipeline transverse point finding clamp 6 to slide left and right, and is fixed at a suitable distance to confirm the horizontal axis position of the water supply pipe. The outer slideway is for the angle fine-tuner 16 to slide. Each section of the leveling plate 5 can be spliced ​​on site according to the specific size of the water supply pipe.

[0037] Before entering the actual construction site, it is unknown whether there is space at the bottom of the water supply pipe to place the leveling plate 5. Figure 6The upper end of the horizontal point-finding clamp 6 is designed to be a trapezoidal structure, the middle fulcrum is set as a cubic column (non-rotatable), and the lower end is set as a horizontal plate. The upper trapezoidal structure is used to clamp the water supply pipe, and the lower horizontal plate is used for it to slide left and right along the leveling plate 5. Therefore, the leveling plate 5 can be set at the front end of the water supply pipe or the lower end of the water supply pipe to adapt to various on-site conditions.

[0038] The right-angle vertical frame 4 includes a vertical rod and a horizontal rod. The partition dial 7 is fixed on the vertical rod through a partition dial fixture 8. A pipeline partition wire extractor 10 is provided on the vertical rod, and the pipeline partition wire extractor 10 is fixedly connected to the center of the partition dial 7. The vertical rod is also provided with a pipe wall upper end fixing rod 9. The vertical rod of the right-angle vertical frame 4 is designed as a telescopic structure, and the vertical rod is made of stainless steel to facilitate it to maintain a vertical state. The wire in the pipeline partition wire extractor 10 is a plasticized steel wire with good toughness and good wear resistance. The pipeline partition wire extractor 10 is provided with an automatic wire winding device.

[0039] When in use, the pipe partitioning wire extractor 10 is aligned with the center of the water supply pipe, and the fixing rod 9 at the upper end of the pipe wall is hung at the top of the outer wall of the water supply pipe. The vertical pendulum 3 coincides with the vertical rod of the right-angle vertical frame 4. The partitioning dial 7 includes a horizontal transverse axis 13, a right diagonal line 14 with an angle of 45 degrees to the horizontal transverse axis 13, and a left diagonal line 15 with an angle of 135 degrees to the horizontal transverse axis 13. The water supply pipe is divided into three parts: upper, middle and lower parts by the left diagonal line 15 and the right diagonal line 14 of the partitioning dial 7. Figure 2 As shown, the sector gce is the upper part, the sector fch is the lower part, the center angle between the two is 90 degrees, and the remaining sectors fcg and ech are the middle part. The extension lines of the left diagonal 15 and the right diagonal 14 of the partition scale 7 and the pipe wall where they intersect the water pipe are provided with water pipe wall clamps.

[0040] Working principle: First, pre-assemble the leveling plate 5 according to the size of the on-site water supply pipe, and assemble the right-angle vertical frame 4 with the leveling plate 5. Use the gravity of the vertical pendulum 3 to determine the vertical direction near the center of the water supply pipe. When the pendulum 12 stops swinging, place the leveling plate 5 with the right-angle vertical frame 4 fixed on it at the front end of the water supply pipe or the lower end of the water supply pipe. The right-angle vertical frame 4 and the vertical pendulum 3 coincide to determine the vertical and horizontal directions. Adjust the angle fine-tuning device 16 to place the leveling plate 5 horizontally on the ground. Then slide the pipeline transverse point clamping plates 6 on both sides of the leveling plate 5 toward the water supply pipe and clamp the water supply pipe. At this time, determine the horizontal left axis point a and the horizontal right axis point b. The distance between points a and b is measured by a tape measure to obtain the pipe diameter. Calculate the pipe radius to determine the midpoint of points a and b, i.e. point c. At this time, adjust the position of the partition dial fixture 8 on the right-angle vertical frame 4 so that the pipeline partition wire extractor 10 coincides with point c, and fix the partition dial fixture 8 at the same time. Pull the wire inside the pipeline partition wire extractor 10 to make it follow the right diagonal line 14 and the left diagonal line 15 on the partition dial fixture 8 to the outer wall of the water supply pipe. At this time, the upper right endpoint e, the lower left endpoint f, the upper left endpoint g, and the lower right endpoint h are determined. You can use a marker to draw partition lines on the pipe wall. If it is inconvenient to draw partition lines on the pipe wall, you can use steel wire to pull the wire and fix it at the position of the partition points at both ends of the water supply pipe, or you can use the water supply pipe outer wall clamp 1 and the water supply pipe inner wall clamp 2 to fix it.

[0041] Although the functions and working processes of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the above-mentioned specific functions and working processes. The above-mentioned specific implementation methods are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, which are all within the protection of the present invention.
