Description

Technical Field

[0001] This utility model relates to a device for rapid detection of hydrogen sulfide in the cabins of fishing vessels, belonging to the field of hydrogen sulfide detection technology. Background Technology

[0002] During the storage of catches on fishing vessels, hydrogen sulfide gas is easily produced due to the decomposition of the fish. The production of hydrogen sulfide is highly insidious and unpredictable, easily causing crew members to become complacent and fail to detect it. Hydrogen sulfide is extremely toxic; inhaling even a small amount within a short period can cause disability or death, and rescue efforts are extremely difficult. Therefore, the best approach is to effectively prevent such incidents from occurring.

[0003] Hydrogen sulfide is highly toxic, denser than air, and easily accumulates in the bottom of the hold. Crew members entering fish holds without proper testing are at high risk of poisoning. Current detection methods typically involve installing hydrogen sulfide measuring probes inside the holds. However, installing probes in all holds is costly and increases the burden on fishermen. Therefore, due to cost considerations, most ordinary fishing vessels are not equipped with dedicated detection devices for the fishing environment. Summary of the Invention

[0004] The purpose of this invention is to provide a device for rapid detection of hydrogen sulfide in fishing vessel cabins. This device can reach deep into the fish cabin through hatches or depth sounding holes on the ship's deck to achieve rapid detection of hydrogen sulfide concentrations at different heights. Therefore, there is no need to install hydrogen sulfide measuring probes in each cabin. Detection is only performed when needed (e.g., before personnel need to enter the cabin), effectively ensuring the safety of crew members while also making the corresponding costs acceptable to fishermen.

[0005] The present invention adopts the following technical solution:

[0006] A device for rapid detection of hydrogen sulfide in fishing vessel cabins includes a measuring rod structure 2, a measuring probe 1, and a control host 4. The measuring rod structure 2 includes a main pipe 201 and an inner tube 202. The lower end of the main pipe 201 extends into the bottom of the fish cabin, and the upper end can extend out of the fish cabin. A connecting component 8 is fixed to the bottom of the inner tube 202. The connecting component 8 extends laterally beyond the main pipe 201 through a vertical sliding groove opened on the wall of the main pipe and is fixedly connected to the measuring probe 1. The signal line of the measuring probe 1 extends upward through the inner tube 202 into the fish cabin and is connected to the control host 4.

[0007] Preferably, the connecting component 8 is a tubular structure, through which the signal line of the measuring probe 1 extends into the measuring rod structure 2 and extends upward from the opening in the middle of the connecting component 8.

[0008] Preferably, the area above the fish tank is an unobstructed open space.

[0009] Preferably, it also includes a measuring hole element 6, which has an opening at the top of the fish tank and is fixedly installed at the opening. The measuring hole element 6 has an openable and closable through hole. Normally, the through hole is closed. When hydrogen sulfide detection is required, the through hole is opened and the measuring rod structure 2 is inserted to the bottom.

[0010] Preferably, the measuring rod structure 2 extends from the fish hatch opening into the interior of the fish hatch.

[0011] Furthermore, the bottom of the fish compartment corresponding to the position of the measuring rod structure 2 has a small protrusion for supporting the main tube 201.

[0012] Preferably, the vertical sliding grooves are a pair, symmetrically arranged at 180° with respect to the central axis of the measuring rod structure 2; correspondingly, the measuring probes 1 are also a pair, also arranged in a 180° supporting configuration with respect to the central axis of the measuring rod structure 2.

[0013] Preferably, a locking device is provided between the inner tube 202 and the main tube 201 at a location outside the fish tank; or no locking device is provided between the inner tube 202 and the main tube 201, and the inner tube 202 is inspected by hand by the operator.

[0014] Preferably, the bottom of the vertical sliding groove is 30cm above the bottom of the fish pond. This height is the standard measurement height. At this height, the embedded tube 202 is at its lowest point, and the main tube 201 and the embedded tube 202 do not need to be locked.

[0015] Preferably, it also includes an alarm system 5, which activates an audible and visual alarm when the detected concentration exceeds a set value.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1) Reduce the cost of hydrogen sulfide detection: There is no need to install hydrogen sulfide measuring probes in every fish hold. Instead, the detection device can be inserted into the fish hold for real-time detection as needed. For ordinary fishing boats, this greatly improves safety performance. For high-end fishing boats, it can also greatly reduce the cost of installing hydrogen sulfide probes in every fish hold.

[0018] 2) Multi-height measurement: The vertical height of the detection probe can be adjusted by using the sliding between the main pipe and the sleeve, as well as the guiding effect of the vertical slide groove. This allows for rapid detection of hydrogen sulfide concentration at different heights, providing a more comprehensive understanding of the distribution of toxic gas concentrations at different heights.

[0019] 3) Rapid detection: The probe can be inserted directly through the hatch or a specific opening (such as a depth sounding hole) without opening the hatch, thus avoiding the risk of gas leakage;

[0020] 4) Alarm mechanism: It has audible and visual alarm functions, and issues different alarms according to the concentration level (e.g., level two alarm) to facilitate the implementation of corresponding countermeasures;

[0021] 5) Portable and flexible: Lightweight structure, suitable for use on fishing boats, and easy to operate;

[0022] 6) Low cost: Components are common, manufacturing costs are low, and it is easy to promote. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] A device for rapid detection of hydrogen sulfide in the cabins of fishing vessels includes a measuring rod structure 2, a measuring probe 1, and a control host 4;

[0032] Combination Figure 1 and Figure 2 The measuring rod structure 2 includes a main tube 201 and an inner tube 202; the lower end of the main tube 201 extends into the bottom of the fish tank, and the upper end can extend out of the fish tank; a connecting component 8 is fixed at the bottom of the inner tube 202; the connecting component 8 extends laterally out of the main tube 201 through a vertical sliding groove opened on the wall of the main tube, and is fixedly connected to the measuring probe 1; the signal line of the measuring probe 1 extends upward out of the fish tank through the inner tube 202 and is connected to the control host 4.

[0033] It should be noted that, attached Figure 1 and 2 The vertical sliding groove was not drawn in detail in either case. Figure 1 The location of the vertical sliding groove is marked in the attached figure, labeled 7.

[0034] In this embodiment, such as Figure 2 The connecting component 8 is a tubular structure. The signal line of the measuring probe 1 extends into the measuring rod structure 2 through the tubular structure and extends upward from the opening in the middle of the connecting component 8.

[0035] In this embodiment, the space above the fish cabin is an unobstructed open space, which does not affect the vertical extension of the measuring rod structure 2.

[0036] In this embodiment, see Figure 1 It also includes a measuring hole element 6, which has an opening at the top of the fish tank and is fixedly installed at the opening. The measuring hole element 6 has an openable and closable through hole. Normally, the through hole is closed. When hydrogen sulfide detection is required, the through hole is opened and the measuring rod structure 2 is inserted to the bottom.

[0037] In this embodiment, the bottom of the fish compartment corresponding to the position of the measuring rod structure 2 has a small protrusion for supporting the main tube 201.

[0038] In this embodiment, the vertical sliding groove has a pair, such as Figure 2 The measuring rod structure 2 is symmetrically arranged at 180° with respect to its central axis; correspondingly, there is also a pair of measuring probes 1, which are also arranged in a 180° opposing arrangement with respect to the central axis of the measuring rod structure 2.

[0039] In this embodiment, see Figure 2 The bottom of the vertical sliding groove is 30cm above the bottom of the fish pond. This is the standard measurement height, and the embedded tube 202 is at its lowest point at this height.

[0040] In this embodiment, a locking device is provided between the inner tube 202 and the main tube 201 at the part outside the fish tank; it should be noted that the locking device is not shown in the figure, and the locking device may be a pin or the like.

[0041] Alternatively, the inner tube 202 and the main tube 201 may not be locked. The inner tube 202 can be inspected by hand by the operator. Especially when the measurement height is 30cm from the bottom, the bottom of the vertical slide groove has a blocking effect on the connecting part 8. At this time, it is not necessary to lock it to ensure that the inner tube 202 is in a stable state.

[0042] In this embodiment, an alarm system 5 is also included. When the detected concentration exceeds the set value, an audible and visual alarm is activated. The audible and visual alarm system 5 can preferably be a two-level audible and visual alarm, with two threshold levels: a low-limit warning and a high-limit alarm. When the detected concentration exceeds the set value, the corresponding audible and visual alarm is activated.

[0043] In this embodiment, the portion of the inner tube 202 extending out of the main tube 201 has a scale that can directly indicate the distance between the measuring probe 1 and the bottom of the fishpond.

[0044] When hydrogen sulfide concentration testing is required, the operator opens the cover of the measuring hole element 6, inserts the measuring rod structure 2 through the measuring hole into the bottom of the fishpond, and places it on the small protrusion at the bottom, with the measuring height at 30cm from the bottom (no locking is required at this time). Connect the signal line of the measuring probe to the electrical control box to perform the test. After the test is completed, the operator pulls the measuring rod structure 2 out of the fishpond as a whole and closes the cover of the measuring hole element 6 again.

[0045] Example 2:

[0046] See Figure 3 The difference between this embodiment and Embodiment 1 is that the measuring rod structure 2 extends from the fish hold opening into the interior of the fish hold. There is no separate measuring hole element 6.

[0047] The rest is the same as in Example 1.

[0048] Example 3:

[0049] See Figures 4-5 The difference between this embodiment and Embodiment 1 is that the operator pulls the embedded tube 202 to detect hydrogen sulfide at different water levels in the fishpond, so as to obtain more comprehensive detection data.

[0050] Because the inner tube 202 extending from the top of the main tube 201 has a scale, the height of the measuring probe 1 from the bottom of the fish pond can be directly seen.

[0051] At this time, the main tube 201 and the inner tube 202 can be locked together by a locking device (such as a pin) to allow for longer-term testing.

[0052] Of course, when the testing time is short, locking can be omitted, and the operator can directly perform the testing by holding the embedded tube 202 by hand.

[0053] This invention eliminates the need for hydrogen sulfide measuring probes in every fish hold. Instead, the detection device can be inserted into the fish hold for immediate detection as needed. This significantly improves safety for ordinary fishing vessels and greatly reduces the cost of installing hydrogen sulfide probes in each fish hold for high-end fishing vessels. The probe's height can be adjusted by utilizing the sliding between the main pipe and the sleeve, as well as the guiding effect of the vertical groove. This allows for rapid detection of hydrogen sulfide concentrations at different heights, providing a more comprehensive understanding of the distribution of toxic gas concentrations at various heights. The probe can be inserted directly through the hatch or a specific opening (such as a depth sounding hole), eliminating the need to open the hold and avoiding the risk of gas leakage. It features an audible and visual alarm function, issuing different alarms based on the concentration level (e.g., a level two alarm) to facilitate appropriate response measures. The lightweight structure is suitable for use on fishing vessels, and operation is simple. The components are common, resulting in low manufacturing costs and easy adoption.

[0054] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should all fall within the scope of protection claimed by the present utility model.
