Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline anti-splash technology, and in particular relates to a pipeline anti-splash device for chemical emergency management. Background Technology
[0002] Chemical emergency management pipelines are critical facilities specifically designed to respond to sudden accidents (such as leaks, fires, and explosions) during chemical production. They are typically made of special materials (such as stainless steel, alloys, or composite materials) that are corrosion-resistant, pressure-resistant, and high-temperature-resistant. They have functions such as rapid shut-off, pressure relief, flow diversion, or inert gas protection. These pipelines are often linked with emergency valves, sensors, and automated control systems to ensure the rapid isolation of hazardous sources, transfer of harmful substances, or injection of extinguishing media in the event of an emergency, thereby curbing the escalation of the accident and protecting personnel and the environment. Their design must comply with stringent international standards (such as API and ASME) and they must be regularly inspected and maintained to ensure reliability under extreme operating conditions. They are an indispensable hardware support for emergency plans in chemical enterprises.
[0003] Existing technologies disclose several utility model patents in the field of pipeline splash prevention. Among them, utility model patent application number CN220506074U discloses a pipeline splash prevention device for chemical safety. Specifically, this utility model relates to a pipeline splash prevention device for chemical safety, including a pipeline and a flange connecting the pipelines. A protective cover is fitted over the flange, comprising an upper cover and a lower cover, which are interlocked by a hinge at the left end and a bolt at the right end, facilitating the replacement of the sealing ring. A liquid storage tank is installed at the bottom of the lower cover. The protective cover covers the entire flange and is locked on both sides by locking rings to prevent chemical liquid from leaking and splashing at the flange connection point, thus preventing accidents and pollution. A sealing ring is provided on the outside of the flange, embedded in an installation groove inside the protective cover. The sealing ring has a U-shaped cross-section. The protective cover and the sealing ring work together to block chemical liquid leakage and splashing. A guide groove is provided on the side of the sealing ring close to the flange, surrounding the flange connection point and guiding the leaked chemical liquid to the liquid storage tank, preventing the chemical liquid from accumulating and corroding inside the protective cover in the event of a leak.
[0004] While existing pipeline systems are relatively mature in terms of splash protection design, they still have certain limitations in leak detection. Due to the obstruction of the pipeline structure or external protective layer, it is difficult to detect minor leaks in the early stages through visual inspection or conventional detection methods, which makes it impossible to quickly identify potential risks. In particular, during the transportation of high-pressure or corrosive media, hidden leaks may expand due to not being detected in time, increasing safety risks.
[0005] Based on this, this utility model designs a pipeline anti-splash device for chemical emergency management to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to address the limitations of existing pipeline systems, which, while having relatively mature anti-splash designs, still have certain limitations in leak detection. Due to the obstruction of the pipeline structure or external protective layer, it is difficult to detect minor leaks in the early stages of a leak through visual inspection or conventional detection methods, resulting in the inability to quickly identify potential risks. This is especially true during the transportation of high-pressure or corrosive media, where concealed leaks may expand due to lack of timely detection, increasing safety risks. Therefore, this utility model proposes a pipeline anti-splash device for chemical emergency management.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A pipeline anti-splash device for chemical emergency management includes a first pipeline and a second pipeline. The opposite surfaces of the first pipeline and the second pipeline are fitted with connecting plates, and the two connecting plates are fixedly connected by bolts. The first pipeline and the second pipeline are fitted with the same anti-leakage device, and an alarm device is connected through the anti-leakage device.
[0009] The leak-proof device includes a first housing and a second housing, which are secured to the outside of two connecting plates by a sealing gasket.
[0010] The alarm device includes a water receiving box, which is connected through the second housing. A humidity sensor is connected through the water receiving box, and a wire is fixedly connected to the outside of the humidity sensor. One end of the wire is fixedly connected to a buzzer-type alarm, and a locking plate is fixedly connected to one side of the buzzer-type alarm. The locking plate is fixedly connected to the outside of the water receiving box.
[0011] As a further description of the above technical solution:
[0012] The leak-proof device also includes two mounting blocks and two rectangular blocks. The two mounting blocks are symmetrically mounted on the outside of the first housing, and the two rectangular blocks are symmetrically mounted on the outside of the second housing. Rectangular grooves are formed in the mounting blocks, and sliding grooves are symmetrically formed in the mounting blocks. A pressing block is provided in the rectangular groove, and a slider is provided in the sliding groove. A return spring is fixedly connected in the pressing block. One end of the return spring is fixed in the pressing block, and the other end is fixed in the rectangular groove. Its elastic force direction is consistent with the movement trajectory of the pressing block. This design allows the pressing block to quickly reset after being released from the pressing force of the rectangular block and maintain a stable snap-fit state. The preload of the spring has been optimized to ensure a firm snap-fit while avoiding disassembly difficulties due to excessive elastic force, thus balancing installation convenience and structural strength.
[0013] The pull-back spring is fixedly connected inside the rectangular groove.
[0014] As a further description of the above technical solution:
[0015] The extrusion block and the rectangular groove form a sliding connection, and the slider and the slide groove form a sliding connection. When the slider slides along the slide groove, the fit clearance is precisely designed to ensure the stable guidance of the extrusion block in the rectangular groove and to prevent shaking due to loosening. This fit method ensures that the extrusion block maintains linear movement during the pressing and resetting process, avoiding deviation or jamming, and ensuring that the first housing and the second housing can be accurately aligned during rapid installation, thereby improving sealing and structural stability.
[0016] As a further description of the above technical solution:
[0017] The size of the extrusion block is slightly smaller than that inside the rectangular groove, and the extrusion surface of the extrusion block is set to be arc-shaped.
[0018] As a further description of the above technical solution:
[0019] The rectangular block has a slot, and the extrusion block is engaged in the slot.
[0020] As a further description of the above technical solution:
[0021] The monitoring end of the humidity sensor is located inside the water collection box.
[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0023] 1. In this utility model, when a leak occurs at the connection between the first pipe and the second pipe, the fluid seeps into the interior of the first and second housings and eventually collects in the water receiving box. The water receiving box has a built-in humidity sensor to monitor the moisture content in real time. Once the leaked liquid is detected, a buzzer alarm is immediately triggered to warn the operator, effectively avoiding safety hazards caused by the failure to detect the leak in time.
[0024] 2. In this utility model, when the first housing and the second housing are installed, the two housings are aligned and pressed. When the extrusion block enters the rectangular block, it is squeezed by the slot and slides along the rectangular slot and is embedded in the rectangular block. When the extrusion force disappears, the pull-back spring drives the extrusion block to reset, so that it is firmly locked in the rectangular block, thereby realizing the quick locking of the first housing and the second housing, ensuring that the installation is firm and easy to disassemble and maintain.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0032] Please see Figures 1-4 ,
[0033] First embodiment:
[0034] This utility model provides a technical solution: a pipeline anti-splash device for chemical emergency management, including a first pipeline 1 and a second pipeline 2. The opposite surfaces of the first pipeline 1 and the second pipeline 2 are fitted with connecting plates 3, and the two connecting plates 3 are fixedly connected by bolts. The first pipeline 1 and the second pipeline 2 are fitted with the same anti-leakage device 4, and an alarm device 5 is connected through the anti-leakage device 4.
[0035] The leak-proof device 4 includes a first housing 41 and a second housing 48, which are secured to the outside of the two connecting plates 3 by a sealing gasket.
[0036] Specifically, such as Figure 2-3As shown, the leak-proof device 4 also includes two mounting blocks 42 and two rectangular blocks 49. The two mounting blocks 42 are symmetrically mounted on the outside of the first housing 41, and the two rectangular blocks 49 are symmetrically mounted on the outside of the second housing 48. A rectangular groove 43 is provided in the mounting block 42, and a sliding groove 44 is symmetrically provided in the mounting block 42. A pressing block 45 is provided in the rectangular groove 43, and a slider 46 is provided in the sliding groove 44. A return spring 47 is fixedly connected in the pressing block 45 and is fixedly connected in the rectangular groove 43. A sliding connection is formed between the pressing block 45 and the rectangular groove 43, and a sliding connection is formed between the slider 46 and the sliding groove 44. The size of the pressing block 45 is slightly smaller than that in the rectangular groove 43. The pressing surface of the pressing block 45 is set to be arc-shaped. A slot is provided in the rectangular block 49, and the pressing block 45 is locked in the slot.
[0037] During operation, when a leak occurs at the connection between the first pipe 1 and the second pipe 2, the fluid seeps into the interior of the first housing 41 and the second housing 48, and eventually collects in the water collection box 51. The water collection box 51 has a built-in humidity sensor 52 that monitors the moisture content in real time. Once the leaked liquid is detected, a buzzer alarm 54 is immediately triggered to warn the operator, effectively avoiding safety hazards caused by the failure to detect the leak in time.
[0038] Second embodiment:
[0039] Specifically, such as Figure 4 As shown, the alarm device 5 includes a water receiving box 51, which is connected through the second housing 48. A humidity sensor 52 is connected through the water receiving box 51. A wire 53 is fixedly connected to the outside of the humidity sensor 52. One end of the wire 53 is fixedly connected to a buzzer 54. The buzzer 54 quickly receives the trigger signal from the humidity sensor 52 through the wire 53, realizing an instant audible and visual alarm. This combination method not only ensures the stability of signal transmission, but also simplifies the difficulty of troubleshooting the wiring during maintenance.
[0040] A locking plate 55 is fixedly connected to one side of the buzzer-type alarm 54. The locking plate 55 is fixedly connected to the outside of the water collection box 51. The monitoring end of the humidity sensor 52 is located inside the water collection box 51, directly contacting the potentially leaking liquid to ensure real-time and accurate detection. The water collection box 51's water collection design can quickly collect leaking liquid, expanding the sensor's monitoring range and avoiding detection delays caused by liquid dispersion. The close cooperation between the two significantly improves the sensitivity of leak response, providing a reliable guarantee for early warning.
[0041] During operation, when the first housing 41 and the second housing 48 are installed, the two housings are aligned and pressed together. When the extrusion block 45 enters the rectangular block 49, it is squeezed by the slot and slides along the rectangular groove 43 and embeds into the rectangular block 49. When the extrusion force disappears, the pull-back spring 47 drives the extrusion block 45 to reset, so that it is firmly locked in the rectangular block 49, thereby realizing the quick locking of the first housing 41 and the second housing 48, ensuring that the installation is firm and easy to disassemble and maintain.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
