Description
Technical Field
[0001] The utility model relates to the field of pipeline installation, in particular to a pipeline installation safety cover. Background Art
[0002] At present, the interface connection of pipeline systems is usually connected by flange, expansion joint or bellows, and also includes the installation of windows (view mirrors), etc. Since it involves the connection of pipelines, leakage is inevitable. Therefore, each connection represents a huge source of danger. Especially in the occasions of conveying toxic, flammable and corrosive media, once the interface seal is broken and the medium leaks, radial spraying perpendicular to the pipeline will occur, and the hazard radius can reach 40 meters, causing harm or damage to people passing by the pipeline or valuable equipment and precision instruments installed near the pipeline. Therefore, it is necessary to add a safety cover at the pipeline interface as protection.
[0003] However, traditional pipeline safety covers still have certain shortcomings: first, in some cases, the pipeline interface may leak due to loose bolts and other factors, but the current safety cover device cannot effectively collect and treat the toxic gases leaked from multiple groups of safety covers around it; secondly, due to the influence of the gas flow rate inside the pipeline, vibrations may sometimes occur during the use of the pipeline. The current safety cover structure cannot provide stable support for the interface of the pipeline, resulting in squeezing and collision of the interface when vibration occurs, which increases the risk of internal gas leakage.
[0004] Therefore, it is necessary to provide a new pipeline installation safety cover to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by the utility model is to provide a pipeline installation safety cover which can stably support the pipeline structure and conveniently collect the toxic gas leaked from multiple groups of surrounding pipelines.
[0006] In order to solve the above technical problems, the utility model provides a pipeline installation safety cover comprising: a gas pipeline, an interface is provided on the surface of the gas pipeline, an upper safety cover and a lower safety cover are respectively provided at the upper and lower sides of the interface, the upper safety cover and the lower safety cover match each other, the top surface of the upper safety cover is connected with a cylinder, a piston is provided inside the cylinder, the cylinder surface located on the upper side of the piston is connected with a side pipe, the front and rear side surfaces of the lower safety cover are both symmetrically connected to the first support plate, the bottom of the first support plate is rotatably connected to the second support plate, the surfaces of the first support plate and the second support plate are A spring rod is installed between the surfaces, a top plate is arranged at the lower side of the lower safety cover, the bottoms of several second support plates are rotatably connected to the surface of the top plate, a bottom plate is arranged at the lower side of the top plate, ground nails are welded at the four corners of the lower surface of the bottom plate, a fixing cylinder is fixedly connected at the center position of the upper surface of the bottom plate, a threaded rod is arranged inside the fixing cylinder, the top of the threaded rod is fixedly connected to the bottom of the top plate, the front wall surface of the top plate is connected to a mounting plate through a bracket, the surface of the mounting plate is connected to a communicating vessel through bolts, and a negative pressure tank is connected to the lower side of the communicating vessel through a bracket.
[0007] As a further solution of the utility model, an air inlet pipe is connected between the communicating vessel and the negative pressure tank, a valve is installed on the surface of the air inlet pipe, and a telescopic pipe is connected between the communicating vessel and the side pipe.
[0008] Through the above technical solution, when in use, the safety cover structure is first fixed to the interface position on the pipeline. When toxic gas leaks at the interface, the gas is isolated in the safety cover device. When the internal pressure is too high, the piston is pushed upward, and the toxic gas passes through the side pipe into the negative pressure tank. The device is provided with a connecting vessel between the negative pressure tank and the side pipe, thereby connecting the safety covers on multiple groups of surrounding pipelines to this place. If gas leaks also occur in other places, then these toxic gases can be concentrated in one place, which is convenient for workers to handle.
[0009] As a further solution of the utility model, a threaded sleeve is rotatably connected to the surface of the fixing cylinder, and the threaded sleeve is threadedly connected to the threaded rod.
[0010] Through the above technical solution, when the device is used, the safety cover device is fixed to the outside of the interface, and then the threaded sleeve is rotated to move the bottom plate downward, and the ground nails at the bottom of the bottom plate will gradually insert into the ground to support the pipeline interface. When the gas flow rate inside the pipeline is too large or the pipeline vibrates for other reasons, several groups of spring rods between the lower safety cover and the top plate can offset the shaking and keep the structure stable, thereby reducing the risk of gas leakage at the interface.
[0011] As a further solution of the utility model, a second alarm and a control module are installed on the surface of the mounting plate from left to right in sequence, and a differential pressure gauge is installed on the surface of the negative pressure tank. Both the differential pressure gauge and the second alarm are electrically connected to the control module.
[0012] Through the above technical solution, when a large amount of toxic gas is stored inside the negative pressure tank, the value of the differential pressure gauge changes. When the value is greater than a set value, the second alarm will be activated through the control module to remind workers to replace the negative pressure tank.
[0013] As a further solution of the utility model, a vertical rod is fixedly connected to the top of the piston, a return spring is sleeved on the outside of the vertical rod, and the top of the return spring is fixedly connected to the inner wall of the cylinder.
[0014] Through the above technical solution, when the toxic gas inside the safety cover is discharged, the piston will move down again due to the reaction force of the return spring to seal the safety cover device.
[0015] As a further solution of the utility model, a warning light is installed on the top of the cylinder, a touch pressure block is installed on the top of the vertical rod, and a first alarm is installed on the surface of the upper safety cover located on one side of the cylinder. The first alarm and the warning light are electrically connected to the control module.
[0016] Through the above technical solution, when gas leakage occurs at a certain interface position, the piston is pushed up by pressure. At this time, the contact block on the top of the vertical rod will move up and turn on the switch of the top warning light. In this way, workers can know which interface is faulty during inspection. This design facilitates maintenance.
[0017] As a further solution of the utility model, a plurality of mounting holes are provided at the edge positions of the surfaces of the upper safety cover and the lower safety cover, and hexagonal bolts are provided inside the mounting holes.
[0018] Through the above technical solution, the device fixes the upper safety cover and the lower safety cover by setting a plurality of groups of mounting holes and corresponding hexagonal bolts, so that the safety cover device has good sealing and stability.
[0019] Compared with the related art, the pipeline installation safety cover provided by the utility model has the following beneficial effects:
[0020] 1. In the utility model, when in use, first fix the safety cover structure to the interface position on the pipeline. When toxic gas leaks at the interface, the gas is isolated in the safety cover device. When the internal pressure is too large, the piston is pushed upward, and the toxic gas passes through the side pipe into the negative pressure tank. The device is provided with a connecting vessel between the negative pressure tank and the side pipe, so as to connect the safety covers on the surrounding multiple groups of pipelines with the place. If gas leaks also occur in other places, these toxic gases can be concentrated in one place, which is convenient for workers to handle. When more toxic gas is stored in the negative pressure tank, the value of the differential pressure gauge will change. When the value is greater than a set value, the second alarm will be activated through the control module to remind the workers to replace the negative pressure tank.
[0021] 2. In the utility model, when gas leakage occurs at a certain interface position, the piston is pressed up, and the pressure block on the top of the vertical rod moves up and turns on the switch of the top warning light. In this way, workers can know which interface has failed during inspection. This design is convenient for maintenance. In addition, when using the device, first fix the safety cover device to the outside of the interface, and then rotate the threaded sleeve to move the bottom plate downward.

A pipeline installation safety cover includes:
[0030] Gas pipeline 1, the surface of the gas pipeline 1 is provided with an interface 10, and an upper safety cover 2 and a lower safety cover 3 are respectively provided at the upper and lower sides of the interface 10, and the upper safety cover 2 and the lower safety cover 3 match each other, and the top surface of the upper safety cover 2 is connected with a cylinder 22, and a piston 23 is provided inside the cylinder 22, and the surface of the cylinder 22 located on the upper side of the piston 23 is connected with a side pipe 26, and the front and rear side surfaces of the lower safety cover 3 are both symmetrically connected to the first support plate 11 in rotation, and the bottom of the first support plate 11 is rotatably connected to the second support plate 12, and a spring rod 13 is installed between the surfaces of the first support plate 11 and the second support plate 12 A top plate 4 is provided at the lower side of the lower safety cover 3, and the bottoms of several second support plates 12 are rotatably connected to the surface of the top plate 4. A bottom plate 5 is provided at the lower side of the top plate 4, and ground nails are welded at the four corners of the lower surface of the bottom plate 5. A fixing cylinder 14 is fixedly connected to the center position of the upper surface of the bottom plate 5, and a threaded rod 15 is provided inside the fixing cylinder 14. The top of the threaded rod 15 is fixedly connected to the bottom of the top plate 4, and the front wall surface of the top plate 4 is connected to a mounting plate 6 through a bracket, and the surface of the mounting plate 6 is connected to a communicating vessel 21 through bolts, and a negative pressure tank 7 is connected to the lower side of the communicating vessel 21 through a bracket.
[0031] like Figure 1 As shown, an air inlet pipe 20 is connected between the communicating vessel 21 and the negative pressure tank 7 , a valve 19 is installed on the surface of the air inlet pipe 20 , and a telescopic pipe is connected between the communicating vessel 21 and the side pipe 26 .
[0032] When in use, first fix the safety cover structure at the interface 10 on the pipeline. When toxic gas leaks at the interface 10, the gas is isolated in the safety cover device. When the internal pressure is too high, the piston 23 is pushed upward, and the toxic gas passes through the side tube 26 into the negative pressure tank 7. The device is provided with a connecting vessel 21 between the negative pressure tank 7 and the side tube 26, so as to connect the safety covers on multiple groups of surrounding pipelines with this place. If gas leaks also occur in other places, then these toxic gases can be concentrated in one place, which is convenient for workers to handle.
[0033] like Figure 1 As shown, a threaded sleeve is rotatably connected to the surface of the fixing cylinder 14 , and the threaded sleeve is threadedly connected to the threaded rod 15 .
[0034] When using the device, fix the safety cover device to the outside of the interface 10, and then rotate the threaded sleeve to move the bottom plate 5 downward. The ground nails at the bottom of the bottom plate 5 will gradually insert into the ground to support the pipeline interface 10. When the gas flow rate inside the pipeline is too high or the pipeline vibrates for other reasons, several groups of spring rods 13 between the lower safety cover 3 and the top plate 4 can offset the shaking and keep the structure stable, thereby reducing the risk of gas leakage at the interface 10.
[0035] like Figure 1 As shown, the surface of the mounting plate 6 is installed with a second alarm 18 and a control module 16 from left to right in sequence, and the surface of the negative pressure tank 7 is installed with a differential pressure gauge 17 , and both the differential pressure gauge 17 and the second alarm 18 are electrically connected to the control module 16 .
[0036] When more toxic gas is stored in the negative pressure tank 7 , the value of the pressure difference meter 17 changes. When the value is greater than a set value, the second alarm 18 is activated through the control module 16 to remind the worker to replace the negative pressure tank 7 .

[0038] When the poisonous gas inside the safety cover is exhausted, the piston 23 will move downward again due to the reaction force of the return spring 25 to seal the safety cover device.
[0039] like Figure 1 As shown, a warning light 8 is installed on the top of the cylinder 22, a touch pressure block is installed on the top of the vertical rod 24, and a first alarm 9 is installed on the surface of the upper safety cover 2 located on one side of the cylinder 22. The first alarm 9 and the warning light 8 are both electrically connected to the control module 16.
[0040] When gas leakage occurs at a certain interface 10, the piston 23 is pushed up by pressure, and the contact block on the top of the vertical rod 24 moves up and turns on the switch of the top warning light 8. In this way, workers can know which interface 10 is faulty during inspection, and this design facilitates maintenance.
[0041] like Figure 1 As shown, a plurality of mounting holes are provided at the edge positions of the surfaces of the upper safety cover 2 and the lower safety cover 3, and hexagonal bolts are provided inside the mounting holes.
[0042] The device fixes the upper safety cover 2 and the lower safety cover 3 by arranging multiple groups of mounting holes and corresponding hexagonal bolts, so that the safety cover device has good sealing and stability.
[0043] The working principle of a pipeline installation safety cover provided by the utility model is as follows:
[0044] The first step: when in use, first fix the safety cover structure to the position of the interface 10 on the pipeline. When toxic gas leaks at the interface 10, the gas is isolated in the safety cover device. When the internal pressure is too large, the piston 23 is pushed upward, and the toxic gas passes through the side pipe 26 and enters the negative pressure tank 7. The device is provided with a connecting vessel 21 between the negative pressure tank 7 and the side pipe 26, so as to connect the safety covers on the surrounding multiple groups of pipelines with the place. If gas leaks also occur in other places, these toxic gases can be concentrated in one place, which is convenient for workers to handle. When more toxic gases are stored in the negative pressure tank 7, the value of the differential pressure gauge 17 will change. When the value is greater than a set value, the second alarm 18 will be activated through the control module 16 to remind the workers to replace the negative pressure tank 7;
[0045] The second step: when a gas leak occurs at a certain interface 10, the piston 23 is pressed up and the pressure block on the top of the vertical rod 24 moves up and turns on the switch of the top warning light 8, so that workers can know which interface 10 has failed during inspection. This design is convenient for maintenance. In addition, when using this device, first fix the safety cover device to the outside of the interface 10, and then rotate the threaded sleeve to move the bottom plate 5 downward. The ground nails at the bottom of the bottom plate 5 will gradually insert into the ground to support the pipeline interface 10. When the gas flow rate inside the pipeline is too large or the pipeline vibrates for other reasons, several groups of spring rods 13 between the lower safety cover 3 and the top plate 4 can offset the shaking, so that the structure remains stable, thereby reducing the risk of gas leakage at the interface 10.
