Description

Technical Field

[0001] This utility model relates to the field of installation technology, and in particular to a real-time monitoring device for the cleaning effect of ice slurry based on pressure sensing. Background Technology

[0002] Pipeline ice slurry cleaning technology is a highly efficient and environmentally friendly physical cleaning method for water supply networks. Its principle involves injecting ice slurry containing tiny ice crystals into the pipes to be cleaned. Utilizing the fluidity and solid-liquid two-phase properties of the ice slurry, an "ice piston" forms within the pipe. Pumped into the water supply network, the ice piston moves within the pipe under the pressure of upstream municipal water. The scraping and shearing action of the ice slurry effectively removes biofilm, scale, and deposits from the pipe walls.

[0003] Currently, engineering projects commonly use offline methods such as outlet sampling and weighing or infrared thermography to evaluate the cleaning effect. However, these methods suffer from drawbacks such as feedback lag, sparse data points, and inability to locate local defects, leading to frequent over-cleaning or under-cleaning phenomena. This wastes valuable ice slurry media and increases the risk of equipment freezing damage. Pressure fluctuation is one of the most sensitive macroscopic parameters of ice slurry two-phase flow: when ice crystals impact the wall, they generate high-frequency impact pressure pulses, the amplitude and frequency of which are strongly negatively correlated with the scale thickness; however, when the ice crystal concentration is insufficient, the pulsation intensity decays rapidly. By capturing this characteristic signal using a miniature pressure sensor array, the local cleaning intensity can be inverted within milliseconds, providing a closed-loop control basis for online adjustment of ice slurry flow rate, concentration, and residence time. However, when using pressure sensor readings, flange installation is required, but bolting in some locations is very difficult and disassembly is also problematic. Utility Model Content

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0021] Reference Figures 1-7 This is the first embodiment of the present invention, which provides a real-time monitoring device for the cleaning effect of ice slurry based on pressure sensing.

[0022] Specifically, the limiting component 1 includes a first cover plate 11 and a second cover plate 12, a first connecting post 13 connecting the first cover plate 11 and the second cover plate 12, a first sleeve 14 disposed on the outer wall of the first connecting post 13, the first sleeve 14 containing a first sliding groove 141 and a limiting rod 15 disposed inside the first sliding groove 141. A second sliding groove 131 is provided on the outer wall of the first connecting column 13, and a limiting block 151 is provided on the outer wall of the limiting rod 15 that can slide along the inside of the second sliding groove 131; A first limiting plate 132 is provided at one end of the first connecting post 13; A first elastic member 16 is disposed between the first cover plate 11 and the second cover plate 12.

[0023] Both the first cover plate 11 and the second cover plate 12 are disc-shaped. A first connecting post 13 can penetrate both the first cover plate 11 and the second cover plate 12. A first sleeve 14 is fitted onto the outer wall of one end of the first connecting post 13 that passes through the second cover plate 12, and the first sleeve 14 is slidably connected to the first connecting post 13. A first sliding groove 141 extends laterally through the first sleeve 14. Two limiting rods 15 are symmetrically arranged inside the first sliding groove 141. A second sliding groove 131 is provided on the outer wall of the first connecting post 13. The second sliding groove 131 is a downward-sloping groove and is fixedly connected to the outer wall of the limiting rods 15. The limiting block 151 is adapted so that when the first connecting post 13 slides upward, the limiting rod 15 moves outward and one end of the limiting rod 15 slides out of the first sliding groove 141. When the first connecting post 13 moves downward, the limiting block 151 slides along the inside of the second sliding groove 131 and retracts inward. A first limiting plate 132 is fixedly connected to the lower end of the first connecting post 13 to prevent the first connecting post 13 from disengaging from the first sleeve 14. A first elastic element 16 is provided between the first cover plate 11 and the second cover plate 12. The first elastic element 16 is a compression spring and is sleeved on the outside of the first connecting post 13.

[0024] That is, during use, locate the nearest valve pre-reserved port near the ice slurry flushing inlet, attach the second cover plate 12 to the upper surface of the flange of the valve pre-reserved port, and then align the first connecting post 13 with the bolt hole pre-reserved on the flange. It should be noted that at least two first connecting posts 13 are provided; preferably, four are arranged in a circumferential array. First, press the first cover plate 11 and the second cover plate 12. At this time, the first elastic element 16 is compressed, and the first connecting post 13 moves downward, ensuring that the limiting rod 15 retracts inward. Then, place the second cover plate 12 on the upper surface of the flange. When the first connecting post 13 passes through the bolt... After the hole is opened, the first cover plate 11 is released, and then the first elastic element 16 begins to push the first cover plate 11 upward. Subsequently, the first cover plate 11 drives the first connecting post 13 to move upward. At this time, the first sleeve 14 abuts against the lower surface of the second cover plate 12, and at the same time, the limiting rod 15 begins to slide outward. When it continues to move upward, the first cover plate 11 drives the first connecting post 13 to slide upward. However, the limiting rod 15 extends out of the first sliding groove 141 and then abuts against the lower surface of the flange, restricting the first connecting post 13 from continuing to slide upward, thereby installing the first cover plate 11 and the second cover plate 12 on the upper surface of the flange. At the center of the first cover plate 11 and the second cover plate 12, there is a mounting hole 111, which is used to install the probe of the pressure sensor and other components. Example 2

[0025] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] Preferably, the inner wall of the second groove 131 includes a first inclined surface 1311 and a second inclined surface 1312, and the first inclined surface 1311 and the second inclined surface 1312 are attached to the outer surface of the limiting block 151.

[0027] Among them, such as Figure 5 As shown, the second slide groove 131 includes a first inclined surface 1311 and a second inclined surface 1312, and the first inclined surface 1311 and the second inclined surface 1312 are parallel and inclined outward. The first inclined surface 1311 and the second inclined surface 1312 are attached to the outer surface of the limiting block 151. When the first connecting post 13 slides upward, the limiting block 151 slides along the surface of the first inclined surface 1311. Due to the restriction of the first slide groove 141, the limiting block 151 will not move up and down, so the limiting rod 15 will move outward.

[0028] Preferably, a second limiting plate 133 is fixedly connected to the end of the first connecting post 13 away from the first cover plate 11.

[0029] A second limiting plate 133 is fixedly connected to the upper end of the first connecting post 13. The second limiting plate 133 is to prevent the first connecting post 13 from sliding down, that is, the second limiting plate 133 will fall on the upper surface of the first cover plate 11.

[0030] In use, press the first cover plate 11 and the second cover plate 12 with both hands, then pass the first connecting column 13 through the bolt hole of the flange, and then release the first cover plate 11. The first cover plate 11 supports the second limiting plate 133, lifting the first connecting column 13 upward. Then, the limiting block 151 on the outer wall of the limiting rod 15 slides along the surface of the first inclined surface 1311. Then the limiting rod 15 moves outward, the first limiting plate 132 supports the first sleeve 14, the first sleeve 14 abuts against the lower surface of the second cover plate 12, and the limiting rod 15 abuts against the lower surface of the flange, forming a clamp, thereby fixing the pressure sensor inside the pipeline to measure the internal pressure. Example 3

[0031] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, a quick-release piece 2 connects the first cover plate 11 and the second cover plate 12.

[0033] In order to facilitate the compression of the first cover plate 11 and the second cover plate 12, a quick-release piece 2 is installed between the two.

[0034] Preferably, the quick-release component 2 includes a first fixing rod 21 disposed on the outer wall of the second cover plate 12, and the first fixing rod 21 penetrates the first cover plate 11, and the outer wall of the first fixing rod 21 is provided with a fourth sliding groove 211; The first cover plate 11 has a third slide groove 112 inside, and the third slide groove 112 has a second elastic element 22 and a stop rod 23 inside.

[0035] The first fixing rod 21 is fixed to the upper surface of the second cover plate 12 and passes through the first cover plate 11. The outer wall of the first fixing rod 21 is recessed inward to form a fourth sliding groove 211, forming a cylinder with a radius smaller than that of the first fixing rod 21. A third sliding groove 112 is provided inside the first cover plate 11. A second elastic element 22 is fixedly connected to the bottom of the third sliding groove 112. An abutment rod 23 is fixedly connected to the other end of the second elastic element 22. The second elastic element 22 is a compression spring. When the first cover plate 11 slides downward... When the abutment rod 23 slides along the surface of the first fixed rod 21, the second elastic member 22 pushes the abutment rod 23 out when it slides to the fourth sliding groove 211. Then the abutment rod 23 slides into the interior of the fourth sliding groove 211. Due to the first elastic member 16, the first cover plate 11 and the second cover plate 12 tend to move away from each other. At the same time, since the first fixed rod 21 is fixedly connected to the second cover plate 12, the first cover plate 11 and the second cover plate 12 are connected, and at the same time, it will not affect the sliding of the first connecting post 13.

[0036] The side of the abutment rod 23 near the second cover plate 12 is provided with a first buffer surface 231.

[0037] The inner wall of the fourth slide groove 211 is fitted with a first slider 24, and the side of the first slider 24 near the second cover plate 12 is provided with a second buffer surface 241.

[0038] The lower surface of the abutment rod 23 is chamfered to form a first buffer surface 231. A first slider 24 is fitted onto the outer wall of the cylinder formed by the fourth slide groove 211. The lower surface of the first slider 24 is chamfered to form a second buffer surface 241. When operation is required, the first cover plate 11 and the second cover plate 12 are pressed down, and the abutment rod 23 is slid into the fourth slide groove 211. Then, the first sleeve 14 on the outer wall of the first connecting column 13 passes through the bolt hole of the flange. Then, the second cover plate 12 is attached to the upper surface of the flange. Then, the first cover plate 11 is pressed down, and the first buffer surface 231 on the outer wall of the abutment rod 23 slides along the surface of the first slider 24. During this process, the abutment rod 23 slides into the third slide groove 112, while simultaneously compressing the second elastic element 22. Then, the abutment rod 23 slides past the first slider 24, and then the second elastic member 22 pushes the abutment rod 23 out. The abutment rod 23 contacts the second buffer surface 241 on the outer wall of the first slider 24. Then, the first elastic member 16 lifts the first cover plate 11. Then, the abutment rod 23 lifts the first slider 24 upward. When the first slider 24 contacts the upper inner wall of the fourth slide groove 211, the abutment rod 23 begins to slide along the surface of the second buffer surface 241. Then, it disengages from the first slider 24, realizing the separation of the first cover plate 11 and the second cover plate 12. Then, the first cover plate 11 moves upward, driving the first connecting post 13 to move upward. The first connecting post 13 pushes the limiting rod 15 to move outward. The limiting rod 15 abuts against the lower surface of the flange, thereby realizing clamping.

[0039] Preferably, this design fixes the first sleeve 14 to the lower surface of the second cover plate 12. The advantage of this design is that when the first cover plate 11 and the second cover plate 12 are pressed, the first connecting post 13 slides downward. If it does not slide, the first connecting post 13 can be manually pushed downward. Since the first sleeve 14 is fixed, the downward movement of the first connecting post 13 will ensure that the limiting rod 15 retracts inside the first slide groove 141. Then, the first cover plate 11 is pressed to unlock the connection between the first cover plate 11 and the second cover plate 12. Then, the first cover plate 11 lifts the first connecting post 13 and moves it upward. Then, the limiting rod 15 is pushed out and engaged with the lower surface of the flange, thereby installing the monitoring device on the flange. When it is necessary to release, the first cover plate 11 is pressed downward. The first cover plate 11 is engaged with the upper inner wall of the fourth slide groove 211 by the abutment rod 23. During this process, the first connecting post 13 moves downward and retracts the limiting rod 15. Then, the first cover plate 11 and the second cover plate 12 are directly disengaged from the flange.

[0040] The first fixing rod 21 has a third limiting plate 212 at one end.

[0041] A third limiting plate 212 is fixedly installed at the upper end of the first fixing rod 21. The function of the third limiting plate 212 is to ensure that the first cover plate 11 can slide along the outer surface of the first fixing rod 21, while preventing the first cover plate 11 from directly detaching.

[0042] The outer wall of the second cover plate 12 is provided with an airbag 3.

[0043] An airbag 3 is fixedly installed on the lower surface of the second cover plate 12. During use, the airbag 3 is squeezed between the second cover plate 12 and the flange to perform a sealing treatment.

[0044] like Figure 7 As shown, at the valve port of the pipeline D that needs to be cleaned, the monitoring device is placed on the upper surface of the flange D1 according to the above steps.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
