Description

Technical Field

[0001] This utility model belongs to the field of safety detection technology, specifically relating to a hazardous chemical transportation leakage detection device. Background Technology

[0002] Hazardous chemicals refer to chemicals that possess dangerous properties such as toxicity, corrosivity, explosiveness, flammability, and radioactivity, and may pose a threat to human health, the environment, and equipment. Currently, hazardous chemicals are primarily transported over long distances in tanks by vehicles.

[0003] In the existing technology, transporting hazardous chemicals is a dangerous job. Hazardous chemicals may leak during transportation, and it is difficult for people in the driver's cab to detect leaks in time while the vehicle is in motion, which can lead to serious consequences. Therefore, a hazardous chemical transportation leak detection device is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background art, this utility model proposes a hazardous chemical transportation leakage detection device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The hazardous chemical transportation leakage detection device of this utility model includes a main body; a cavity is opened at the bottom of the main body; multiple sliding grooves are opened on the side wall of the cavity; sliders are slidably connected to the side walls of the multiple sliding grooves; sliding rings are fixedly connected to the side walls of the multiple sliders; multiple first damping springs are fixedly connected to the inner side wall of the sliding rings; the multiple first damping springs are arranged in a circular array; a fixing ring is fixedly connected to the end of the multiple first damping springs; a vertical rod is installed on the inner side wall of the fixing ring; a float is fixedly connected to the end of the vertical rod; a base plate is connected to the bottom of the sliding groove; and multiple detectors are fixedly connected to the top of the base plate.

[0006] Preferably, a first adjusting ring is threadedly connected to the side wall of the vertical rod; a second adjusting ring is threadedly connected to the side wall of the vertical rod; the first adjusting ring and the second adjusting ring are distributed on both sides of the fixed ring.

[0007] Preferably, a protective plate is fixedly connected to the top of the cavity; the protective plate is made of rubber; the protective plate is cylindrical and is used to protect the end of the vertical rod.

[0008] Preferably, multiple detectors are fixedly connected to the bottom of the main body; the multiple detectors are arranged symmetrically.

[0009] Preferably, a first support plate is fixedly connected to the side wall of the main body; a plurality of second damping springs are fixedly connected to the top of the first support plate; and a second support plate is fixedly connected to the top of the plurality of second damping springs.

[0010] Preferably, a sealing gasket is fixedly connected to the bottom of the first support plate; the sealing gasket is annular.

[0011] The beneficial effects of this utility model are:

[0012] This invention provides a hazardous chemical transport leak detection device. Multiple first damping springs eliminate swaying, preventing excessive swaying of the float and thus avoiding false alarms. During transport, the device is placed inside the transport tank, with the float submerged in the liquid. The buoyancy of the liquid lifts the float. When the liquid leaks, the liquid level drops, causing the float to descend along with it, carrying a sliding ring. Upon reaching a certain distance, the bottom of the sliding ring contacts the detector surface, triggering an alarm system to notify the driver of the leak and facilitate timely intervention.

[0013] This utility model provides a hazardous chemical transportation leakage detection device. By threading a first adjusting ring and a second adjusting ring to the side of the vertical rod, and distributing the first adjusting ring and the second adjusting ring on both sides of the fixed ring, the height of the vertical rod can be adjusted through the first adjusting ring and the second adjusting ring to keep the float in the normal position. This prevents the height difference between the main body and the liquid surface from being too large or too small. If the height difference is too large, the device will only be able to detect when there is a large liquid leakage. If the height difference is too small, the device will alarm when there is no liquid leakage. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Specific implementation examples are given below.

[0025] Please see Figure 1 - Figure 3This utility model provides a hazardous chemical transportation leakage detection device, including a main body 1; a cavity 11 is formed at the bottom of the main body 1; multiple sliding grooves 12 are formed on the side wall of the cavity 11; sliders 13 are slidably connected to the side walls of the multiple sliding grooves 12; sliding rings 14 are fixedly connected to the side walls of the multiple sliders 13; multiple first damping springs 15 are fixedly connected to the inner side wall of the sliding rings 14; the multiple first damping springs 15 are arranged in a circular array; and fixed rings 16 are fixedly connected to the ends of the multiple first damping springs 15; the fixed rings 16... A vertical rod 17 is installed on the inner side wall of the body 1; a float 18 is fixedly connected to the end of the vertical rod 17; a base plate 19 is connected to the bottom of the slide groove 12; multiple detectors 101 are fixedly connected to the top of the base plate 19; during operation, a cavity 11 is opened at the bottom of the main body 1, and multiple slide grooves 12 are opened on the side wall of the cavity 11. Multiple sliders 13 are slidably connected to the side wall of the slide groove 12, and sliding rings 14 are fixedly connected to the side wall of the multiple sliders 13. The sliding rings 14 can slide on the side wall of the cavity 11 by the sliders 13 sliding on the side wall of the slide groove 12. The sliding ring 14 has multiple first damping springs 15 fixedly connected to its inner wall. A fixing ring 16 is fixedly connected to the end of each first damping spring 15. A vertical rod 17 is installed on the side wall of the fixing ring 16, and a float 18 is fixedly connected to the end of the vertical rod 17. A base plate 19 is installed at the bottom of the main body 1, and multiple detectors 101 are fixedly connected to the top of the base plate 19. During transportation, shaking may occur. The multiple first damping springs 15 can eliminate this shaking and prevent the float 18 from shaking excessively, which could easily cause false alarms. In this process, the device is placed in the transport tank, and the float 18 is placed in the liquid in the tank. The buoyancy of the liquid can lift the float 18. When the liquid in the tank leaks, the liquid level will drop. When the liquid level drops, the float 18 floating in the liquid will also drop. As it drops, it will bring the sliding ring 14 down with it. When it drops a certain distance, the bottom of the sliding ring 14 will contact the surface of the detector 101. The contact can trigger the alarm system, which can inform the driver that the tank is leaking, so that the driver can deal with it in time.

[0026] Furthermore, such as Figure 3 and Figure 4As shown, a first adjusting ring 2 is threadedly connected to the side wall of the vertical rod 17; a second adjusting ring 21 is threadedly connected to the side wall of the vertical rod 17; the first adjusting ring 2 and the second adjusting ring 21 are distributed on both sides of the fixed ring 16; during operation, the first adjusting ring 2 and the second adjusting ring 21 are threadedly connected to the side of the vertical rod 17, and the first adjusting ring 2 and the second adjusting ring 21 are distributed on both sides of the fixed ring 16. The height of the vertical rod 17 can be adjusted by the first adjusting ring 2 and the second adjusting ring 21, so that the float 18 is in the normal position, preventing the height difference between the main body 1 and the liquid surface from being too large or too small. If the height difference is too large, the device will only be able to detect when there is too much liquid leakage; if the height difference is too small, the device will alarm when there is no liquid leakage.

[0027] Furthermore, such as Figure 2 As shown, a protective plate 3 is fixedly connected to the top of the cavity 11; the protective plate 3 is made of rubber; the protective plate 3 is cylindrical and is used to protect the end of the vertical rod 17; during operation, the protective plate 3 is fixedly connected to the top of the cavity 11. When the transported tank is inspected, if shaking occurs, the top of the vertical rod 17 will collide with the inner wall of the main body 1. The protective plate 3 can buffer the force generated by the collision and prevent the vertical rod 17 from being damaged or broken during the collision, which would cause inconvenience to the subsequent inspection.

[0028] Furthermore, such as Figure 5 As shown, multiple detectors 4 are fixedly connected to the bottom of the main body 1; the multiple detectors 4 are symmetrically arranged; during operation, multiple detectors 4 are fixedly connected to the bottom of the main body 1, and the multiple detectors 4 are symmetrically arranged. When the float 18 is damaged during shaking, the liquid can be detected by multiple detectors 4 to prevent liquid leakage from going undetected. The multiple detectors 4 provide double protection, ensuring the transportation of hazardous chemicals.

[0029] Furthermore, such as Figure 1 As shown, a first support plate 5 is fixedly connected to the side wall of the main body 1; a plurality of second damping springs 51 are fixedly connected to the top of the first support plate 5; a second support plate 52 is fixedly connected to the top of the plurality of second damping springs 51; during operation, the first support plate 5 is fixedly connected to the side wall of the main body 1, a plurality of second damping springs 51 are fixedly connected to the top of the first support plate 5, and a second support plate 52 is fixedly connected to the top of the plurality of second damping springs 51. When the device is installed on the tank, the tank will shake during transportation. The energy generated by the shaking can be absorbed by the plurality of second damping springs 51, which can reduce the impact of the shaking and provide a guarantee for the device to perform leak detection.

[0030] Furthermore, such as Figure 5As shown, a sealing gasket 6 is fixedly connected to the bottom of the first support plate 5; the sealing gasket 6 is annular; during operation, the sealing gasket 6 is fixedly connected to the bottom of the first support plate 5. When detecting liquid leakage, it is necessary to maintain the overall sealing so that the device can detect the liquid.

[0031] Working principle: During operation, a cavity 11 is opened at the bottom of the main body 1. Multiple sliding grooves 12 are opened on the side wall of the cavity 11. Multiple sliders 13 are slidably connected to the side wall of the sliding grooves 12. Sliding rings 14 are fixedly connected to the side wall of the sliders 13. The sliding of the sliders 13 on the side wall of the sliding grooves 12 allows the sliding rings 14 to slide on the side wall of the cavity 11. Multiple first damping springs 15 are fixedly connected to the inner side wall of the sliding rings 14. Fixed rings 16 are fixedly connected to the ends of the first damping springs 15. Vertical rods 17 are installed on the side wall of the fixed rings 16. Floats 18 are fixedly connected to the ends of the vertical rods 17. A base plate 19 is installed at the bottom of the main body 1. Multiple detectors 101 are fixedly connected to the top of the base plate 19. During transportation, shaking may occur. The first damping spring 15 can eliminate swaying and prevent the float 18 from swaying too much, which could easily cause a false alarm. During transportation, the device is placed in the transport tank, and the float 18 is placed in the liquid in the tank. The buoyancy of the liquid can lift the float 18. When the liquid in the tank leaks, the liquid level will drop. As the liquid level drops, the float 18 floating in the liquid will also drop, bringing the sliding ring 14 down with it. When it drops a certain distance, the bottom of the sliding ring 14 will contact the surface of the detector 101. This contact can trigger the alarm system, which can inform the driver that the tank is leaking, allowing the driver to handle it in time. During operation, the first adjusting ring 2 and the second adjusting ring 2 are threadedly connected to the side of the vertical rod 17. Adjusting ring 21, and distributing the first adjusting ring 2 and the second adjusting ring 21 on both sides of the fixed ring 16, allows adjustment of the height of the vertical rod 17, ensuring the float 18 is in the correct position. This prevents the height difference between the main body 1 and the liquid surface from being too large or too small. An excessively large height difference means the device will only detect excessive liquid leakage, while a too small difference will trigger an alarm even when there is no leakage. During operation, a protective plate 3 is fixedly connected to the top of the cavity 11. When inspecting the transport tank, if shaking occurs, the top of the vertical rod 17 will collide with the inner wall of the main body 1. The protective plate 3 buffers the force of the collision, preventing damage or breakage of the vertical rod 17 during the collision, thus preparing for subsequent inspections. To mitigate the inconvenience of transporting hazardous materials, multiple detectors 4 are fixedly connected to the bottom of the main body 1 during operation. These detectors 4 are symmetrically arranged. If the float 18 is damaged during shaking, the multiple detectors 4 can detect the liquid, preventing leaks from going undetected. This double-layered protection provides assurance for the transportation of hazardous materials. During operation, a first support plate 5 is fixedly connected to the side wall of the main body 1. Multiple second damping springs 51 are fixedly connected to the top of the first support plate 5, and a second support plate 52 is fixedly connected to the top of the second damping springs 51. When the device is installed on the tank, the tank may shake during transportation. The multiple second damping springs 51 absorb the energy generated by the shaking, reducing its impact.To ensure the device can perform leak detection, a sealing gasket 6 is fixedly connected to the bottom of the first support plate 5 during operation. Maintaining an overall seal is crucial for the device to detect liquid leaks.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
