Technical Field
[0001] The utility model relates to the field of safety covers, in particular to a chemical pipeline safety cover. Background Art
[0002] Chemical pipeline safety cover is a safety protection device used for conveying corrosive media in chemical, dye, medicine, pesticide, metallurgy, rare earth, machinery, electricity, electronics, environmental protection, textile, brewing, food, water supply and drainage, petroleum, smelting, papermaking and other industries to prevent the leakage of chemical pipeline conveying substances and cause environmental pollution.
[0003] During the installation of the stainless steel chemical pipeline protective cover in the prior art, the left and right protective covers are respectively put on both sides of the chemical pipeline flange connection, and then the left and right protective covers are fixedly connected with bolts to complete the installation of the chemical pipeline protective cover. This makes it inconvenient to quickly disassemble the chemical pipeline protective cover when performing maintenance on pipeline leakage in the later stage, and the practicality is low.
[0004] Since the stainless steel chemical pipeline protective cover in the prior art uses bolts to fix the left and right protective covers, it is inconvenient to quickly disassemble the chemical pipeline protective cover during maintenance of the pipeline leakage in the later stage, thereby affecting the efficiency of chemical pipeline maintenance. Moreover, when the chemical pipeline initially leaks, the inspectors cannot observe the internal situation of the stainless steel chemical pipeline protective cover during the pipeline inspection, and thus cannot find the leakage location of the chemical pipeline in time, affecting the emergency repair of the chemical pipeline. Utility Model Content
[0005] Based on this, the purpose of the present invention is to provide a chemical pipeline safety cover to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chemical pipeline safety cover, comprising a chemical pipeline, a No. 1 arc-shaped safety cover and a No. 2 arc-shaped safety cover, wherein the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover are respectively sleeved on the left and right sides of the chemical pipeline, and positioning components are symmetrically arranged between the upper and lower ends of the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover, a through groove is opened in the middle of the No. 2 arc-shaped safety cover, and an observation window is fixedly installed inside the through groove, and pH detection paper is installed on the inner wall of the observation window.
[0007] By adopting the above technical solution, when a leak occurs at the flange connection of a chemical pipeline, the discharged liquid adheres to the surface of the pH test paper, causing the color of the pH test paper to change, making it convenient for inspection personnel to observe and determine the leakage location of the chemical pipeline through the observation window. In addition, through the setting of the positioning component, the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover can be quickly disassembled and assembled, thereby improving the operational efficiency of chemical pipeline maintenance.
[0008] The utility model is further configured as follows: the positioning assembly includes: a first fixed block and a second fixed block, the first fixed block is fixedly installed on one side of the surface of the No. 1 arc-shaped safety cover, the second fixed block is fixedly installed on one side of the surface of the No. 2 arc-shaped safety cover, the first fixed block is provided with a groove near the side adjacent to the second fixed block, the second fixed block is fixedly provided with a limit pin on the surface near the side adjacent to the groove, and one end of the limit pin extends to the inside of the adjacent groove, a limit slot is provided on the surface of one end of the limit pin, the top of the first fixed block is vertically movable through a positioning rod, and one end of the positioning rod extends to the inside of the limit slot, the middle of the positioning rod is fixedly connected to a fixing ring, and one end of the fixing ring is mounted on the surface of the limit pin, the surface of the other end of the positioning rod is covered with a reset spring, and one end of the reset spring is fixedly installed on the inner wall of the groove, and the other end of the reset spring is fixedly connected to the surface of the fixing ring.
[0009] By adopting the above technical solution, when the No. 1 arc-shaped safety cover is docked with the No. 2 arc-shaped safety cover, the limit pins on one side of the second fixed block symmetrical at the upper and lower ends of the No. 2 arc-shaped safety cover will be inserted into the grooves inside the first fixed block corresponding to the upper and lower ends of the No. 1 arc-shaped safety cover. At this time, the inclined surface of one end of the limit pin squeezes the inclined surface of one end of the positioning rod, causing the positioning rod to move away from the limit pin. After the limit pin moves into place, one end of the positioning rod releases the squeezing of the limit pin. At this time, the reset spring elastically resets after being stressed, pushing the fixed ring in the middle of the positioning rod to move, so that one end of the positioning rod is inserted into the limit groove, completing the locking of the limit pin position. In this way, the rapid docking and installation of the chemical pipeline safety cover is facilitated.
[0010] The present invention is further configured such that one end of the positioning rod is configured as an inclined surface, and one end of the limiting pin is configured as an inclined surface that matches the inclined surface at one end of the positioning rod.

When the limit pin squeezes the inclined surface of one end of the positioning rod through the inclined surface of one end, it is convenient to push one end of the positioning rod to move away from the limit pin, thereby reducing the interference caused by the limit pin pushing the positioning rod to move.
[0012] The present invention is further configured such that airbags are symmetrically fixedly mounted on both upper and lower ends of the No. 1 arc-shaped safety cover, and an inflation end is fixedly mounted on one end of the airbag, and one end of the inflation end extends to the outside of the No. 1 arc-shaped safety cover.
[0013] By adopting the above technical solution, after the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover are installed on the surface of the chemical pipeline, the airbag is filled with gas through the inflation end and expands, thereby sealing the gap between the upper and lower ends of the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover, thereby improving the sealing performance of the installation between the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover.
[0014] The present invention is further configured such that arc-shaped sealing rings are fixedly installed on both sides of the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover, and the arc-shaped sealing rings are made of EPDM rubber.
[0015] By adopting the above technical solution, when the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover are docked at the junction of the chemical pipeline, the arc-shaped sealing rings on both sides of the No. 1 arc-shaped safety cover and the No. 2 arc-shaped safety cover are squeezed tightly against the surface of the chemical pipeline, thereby sealing both sides of the chemical pipeline joint.

[0018] The present invention is further configured such that the observation window is made of tempered glass.
[0019] By adopting the above technical solution, the transparent material made of tempered glass can make it easier for workers to observe the situation inside the chemical pipeline safety cover when conducting pipeline inspections.
[0020] The present invention is further configured such that the pH detection paper is fixed to a middle position of an inner wall of the observation window by gluing with transparent glue.
[0021] By adopting the above technical solution, the pH test paper is fixed to the inner wall of the observation window by glue. After the pH test paper is used, it can be torn off and re-pasted with new pH test paper for reuse.

[0030] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0031] The following describes an embodiment of the present invention based on its overall structure.
[0032] A chemical pipeline safety cover, such as Figure 1 - Figure 4As shown, it includes a chemical pipeline 1, a No. 1 curved safety cover 2 and a No. 2 curved safety cover 3. The left and right sides of the chemical pipeline 1 are respectively covered with the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3. Positioning components 4 are symmetrically arranged between the upper and lower ends of the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3. A through groove 301 is opened in the middle of the No. 2 curved safety cover 3, and an observation window 302 is fixedly installed inside the through groove 301. The inner wall of the observation window 302 is installed with pH test paper 303. When a leak occurs at the flange connection of the chemical pipeline 1, the discharged liquid adheres to the surface of the pH test paper 303, causing the color of the pH test paper 303 to change, making it convenient for inspection personnel to observe and determine the leak location of the chemical pipeline through the observation window 302. The setting of the positioning component 4 facilitates the rapid disassembly and assembly between the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3, thereby improving the efficiency of chemical pipeline maintenance.
[0033] See also Figure 1 - Figure 4 The positioning assembly 4 includes: a first fixed block 401 and a second fixed block 402. The first fixed block 401 is fixedly mounted on one side of the surface of the No. 1 arc-shaped safety cover 2, and the second fixed block 402 is fixedly mounted on one side of the surface of the No. 2 arc-shaped safety cover 3. A groove 4011 is provided on the side of the first fixed block 401 close to the adjacent second fixed block 402. A limiting pin 403 is fixedly mounted on the surface of the second fixed block 402 close to the adjacent groove 4011, and one end of the limiting pin 403 extends to the inside of the adjacent groove 4011. The surface of one end of the limiting pin 403 is fixedly mounted on the surface of the second fixed block 402. A limiting groove 4031 is provided on the surface, and a positioning rod 404 is provided on the top of the first fixed block 401 so as to be movable in the vertical direction, and one end of the positioning rod 404 extends to the inside of the limiting groove 4031, and a fixing ring 405 is fixedly connected to the middle part of the positioning rod 404, and one end of the fixing ring 405 is placed on the surface of the limiting pin 403, and a return spring 406 is provided on the surface of the other end of the positioning rod 404, and one end of the return spring 406 is fixedly installed on the inner wall of the groove 4011, and the other end of the return spring 406 is fixedly connected to the surface of the fixing ring 405. When the No. 1 arc-shaped safety cover 2 is docked with the No. 2 arc-shaped safety cover 3, the limit pin 403 on one side of the second fixed block 402 symmetrical at the upper and lower ends of the No. 2 arc-shaped safety cover 3 will be inserted into the groove 4011 inside the corresponding first fixed block 401 at the upper and lower ends of the No. 1 arc-shaped safety cover 2. At this time, the inclined surface of one end of the limit pin 403 squeezes the inclined surface of one end of the positioning rod 404, causing the positioning rod 404 to move away from the limit pin 403. After the limit pin 403 moves into place, one end of the positioning rod 404 releases the squeezing of the limit pin 403. At this time, the reset spring 406 elastically resets after being stressed, pushing the fixing ring 405 in the middle of the positioning rod 404 to move, so that one end of the positioning rod 404 is inserted into the limit groove 4031, completing the locking of the position of the limit pin 403. This method facilitates the rapid docking and installation of chemical pipeline safety covers.
[0034] See also Figure 3 - Figure 4 One end of the positioning rod 404 is configured as an inclined surface, and one end of the limiting pin 403 is configured as an inclined surface that matches the inclined surface of one end of the positioning rod 404. During docking between the first curved safety cover 2 and the second curved safety cover 3, the limiting pin 403 on one side of the second fixing block 402, which is symmetrical at the upper and lower ends of the second curved safety cover 3, is inserted into the groove 4011 inside the corresponding first fixing block 401 at the upper and lower ends of the first curved safety cover 2. When the limiting pin 403 presses the inclined surface of one end of the positioning rod 404 through the inclined surface of one end, it facilitates the movement of one end of the positioning rod 404 away from the limiting pin 403, thereby reducing the interference caused by the limiting pin 403 pushing the positioning rod 404 to move.
[0035] Please refer to Figure 2 . Airbags 5 are symmetrically fixedly mounted on both the upper and lower ends of the No. 1 curved safety cover 2, and an inflation end 501 is fixedly mounted on one end of the airbag 5. One end of the inflation end 501 extends to the outside of the No. 1 curved safety cover 2. The airbag 5 is curved, and after being filled with gas, it can seal the gap between the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 without affecting leakage detection. After the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 are installed on the surface of the chemical pipeline 1, the airbag 5 is filled with gas through the inflation end 501, causing it to expand, sealing the gap between the upper and lower ends of the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3, thereby improving the sealing performance of the installation between the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3.
[0036] See also Figure 2 Arc-shaped sealing rings 6 are fixedly mounted on both sides of the first and second curved safety covers 2, 3. These sealing rings are made of EPDM rubber. When the first and second curved safety covers 2, 3 are docked at the junction of the chemical pipeline 1, the arc-shaped sealing rings 6 on both sides of the first and second curved safety covers 2, 3 are squeezed tightly against the surface of the chemical pipeline 1, thereby sealing both sides of the junction of the chemical pipeline 1.
[0037] See also Figure 1 - Figure 2 The middle of the upper ends of the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 are both provided with curved grooves, and the curved sealing gaskets 7 made of EPDM rubber are fixedly installed inside the curved grooves. After the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 are connected, the curved sealing gaskets 7 in the grooves at the upper ends of the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 seal the intersection of the valve of the chemical pipeline 1, thereby improving the overall sealing performance of the No. 1 curved safety cover 2 and the No. 2 curved safety cover 3 after installation.
[0038] See also Figure 1- Figure 3 The observation window 302 is made of tempered glass. The transparent material of the tempered glass allows the staff to more easily observe the situation inside the chemical pipeline safety cover when conducting pipeline inspections.
[0039] See also Figure 1 - Figure 3 The pH test paper 303 is fixed to the middle position of the inner wall of the observation window 302 by transparent glue. The pH test paper 303 is fixed to the inner wall of the observation window 302 by glue. After the pH test paper 303 is used, it can be torn off and a new pH test paper 303 can be pasted for reuse.
[0040] The working principle of the present invention is as follows: in the installation of the stainless steel chemical pipeline protection cover, when the No. 1 arc-shaped safety cover 2 and the No. 2 arc-shaped safety cover 3 are docked, the limit pin 403 on one side of the second fixed block 402 symmetrical at the upper and lower ends of the No. 2 arc-shaped safety cover 3 will be inserted into the groove 4011 inside the corresponding first fixed block 401 on the upper and lower ends of the No. 1 arc-shaped safety cover 2. At this time, the inclined surface of one end of the limit pin 403 squeezes the inclined surface of one end of the positioning rod 404, causing the positioning rod 404 to move in the direction away from the limit pin 403. After the limit pin 403 moves into place, one end of the positioning rod 404 releases the squeezing of the limit pin 403. At this time, the reset spring 406 elastically resets after being stressed, pushing the fixing ring 405 in the middle of the positioning rod 404 to move, so that one end of the positioning rod 404 is inserted into the limit groove 4031, completing the locking of the position of the limit pin 403, thereby performing the chemical pipeline safety cover. Quick docking installation. When the chemical pipeline safety cover is disassembled, the positioning rod 404 is moved by pulling the positioning rod 404 so that one end of the positioning rod 404 moves out of the limit groove 4031. At this time, the limit of the limit pin 403 is released, and the No. 1 arc-shaped safety cover 2 and the No. 2 arc-shaped safety cover 3 can be separated, thereby realizing the rapid disassembly of the chemical pipeline safety cover. After installation, the interior of the airbag 5 is filled with gas through the inflation end 501, and the airbag 5 expands to seal the gap between the upper and lower ends of the No. 1 arc-shaped safety cover 2 and the No. 2 arc-shaped safety cover 3, and the two sides of the No. 1 arc-shaped safety cover 2 and the No. 2 arc-shaped safety cover 3 are sealed through the arc-shaped sealing ring 6 and the tops of the No. 1 arc-shaped safety cover 2 and the No. 2 arc-shaped safety cover 3 are sealed with the surface of the chemical pipeline 1 through the arc-shaped sealing gasket 7. In later use, the inspection personnel observe the color change of the PH test paper 303 through the observation window 302 to determine whether there is a leak at the junction of the chemical pipeline.
