Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a detachable high-pressure oxygen chamber spray testing device. Background Technology

[0002] Hyperbaric oxygen chambers are core medical devices used in clinical treatment to correct tissue hypoxia and promote functional recovery. Their core treatment mechanism lies in creating an ultra-high pressure oxygen environment (1.4-3 ATA), allowing patients to inhale high concentrations of oxygen, significantly increasing the level of dissolved oxygen in plasma, breaking through the physiological limitations of hemoglobin carrying oxygen under normal pressure, and expanding the oxygen molecule diffusion radius to 3-4 times that under normal conditions, thereby effectively improving oxygen metabolism in deep tissues.

[0003] In the safety operation and maintenance system of a hyperbaric oxygen chamber, the functional verification of the fire sprinkler system is a core component. Current standard operating procedures require manual operation by personnel inside the chamber during drills: one method involves multiple operators holding aloft water collection containers to catch the scattered spray of fire-fighting water from the sprinkler heads; the other requires multiple people to work together to pull a plastic sheet to form a temporary water collection structure. While these two methods can prevent fire-fighting water from wetting delicate equipment inside the chamber (such as multi-functional seats, emergency rescue modules, and communication systems), they have significant drawbacks: First, they are highly dependent on manpower, requiring multiple operators for a single drill, resulting in high labor intensity and coordination costs; second, the operation is time-consuming, easily leading to personnel fatigue; third, there are potential safety risks, as manual shielding may not completely cover the sprinkler area, increasing the risk of leakage.

[0004] Therefore, there is a need to disclose a fire sprinkler testing device to reduce labor costs and improve operational stability. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a detachable high-pressure oxygen chamber spray test device that can achieve directional collection of test water and effectively avoid environmental interference caused by water diffusion in traditional tests.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A detachable hyperbaric oxygen chamber spray test device includes a fluid supply module, which is connected to a pipeline opening and closing module, and the pipeline opening and closing module is connected to a chamber top interface module fixed to the top wall of the hyperbaric oxygen chamber.

[0008] The fluid supply module includes a water storage container;

[0009] The pipeline opening and closing module includes a water supply pipeline connected to the water storage container, and an electromagnetic actuator and a manual shut-off device are arranged in parallel in the middle section of the water supply pipeline.

[0010] The top interface module is selectively connected to either a fire sprinkler terminal or a flow diversion test terminal via a detachable structure; the fire sprinkler terminal includes an atomizing nozzle assembly, and the flow diversion test terminal includes a flow guide valve and a connected flexible flow diversion pipe.

[0011] Furthermore, the water storage container is equipped with a pressurized water inlet and a compressed gas interface.

[0012] Furthermore, the flow guide valve is equipped with a sealing component to enhance the sealing performance between the flow guide valve and the top interface module.

[0013] Furthermore, the sealing component is a sealing ring made of fluororubber.

[0014] Furthermore, the snap-fit ​​connection structure includes an outer groove on the circumference of the top interface module, and an inner groove on the inner wall of the fire sprinkler terminal and the flow guide valve, with ball bearings installed in the inner groove; when the fire sprinkler terminal or the flow guide valve is installed on the top interface module, the ball bearings are embedded in the outer groove.

[0015] Furthermore, the flow guide valve is provided with a lug.

[0016] Furthermore, the electromagnetic actuator is electrically connected to the button switch on the control panel.

[0017] Furthermore, it also includes a water collection device, with the end of the flexible drainage tube extending to the water collection device.

[0018] Furthermore, a flow meter is installed on the water supply pipeline.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model is equipped with a top interface module, which can be detachably connected to a fire sprinkler terminal or a diversion test terminal. The diversion test terminal includes a diversion valve and a connected flexible diversion pipe. When the pipeline needs to be tested, the fire sprinkler terminal can be disassembled and the diversion test terminal can be installed to collect the test water coming out of the pipeline, realizing the directional collection of the test water body. This effectively avoids the environmental interference caused by water diffusion in traditional tests, and eliminates the need for personnel to lift the water, thus reducing labor costs.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 5 As shown, this utility model claims protection for a detachable hyperbaric oxygen chamber spray test device, including a fluid supply module, which is connected to a pipeline opening and closing module, and the pipeline opening and closing module is connected to a chamber top interface module 6 fixed on the top wall of the hyperbaric oxygen chamber 5; wherein, the fluid supply module includes a water storage container 1; the water storage container 1 is provided with a pressurized water inlet 101 and a compressed gas interface 102, water is injected from the pressurized water inlet 101 and gas is injected from the compressed gas interface 102, thereby giving the water in the water storage container 1 a certain pressure, and giving the water supply pipeline 2 a certain high pressure.

[0031] The pipeline opening and closing module includes a water supply pipeline 2 connected to the water storage container 1. A parallel electromagnetic actuator 3 and a manual shut-off device 4 are installed in the middle section of the water supply pipeline 2. Both the electromagnetic actuator 3 and the manual shut-off device 4 can independently control the simultaneous closure of the water supply pipeline 2, providing dual control. The electromagnetic actuator 3 is electrically connected to the button switch on the control panel, enabling remote control. In this embodiment, the electromagnetic actuator 3 is a solenoid valve, and the manual shut-off device 4 is a conventional manual pipeline valve. When the electromagnetic actuator 3 malfunctions due to power failure or other reasons, the manual shut-off device 4 can be manually controlled to close the pipeline.

[0032] The main innovation of this utility model is that the top interface module 6 can be selectively connected to either the fire sprinkler terminal 7 or the diversion test terminal 8 via a detachable structure. The fire sprinkler terminal 7 includes an atomizing nozzle assembly. In normal use, the fire sprinkler terminal 7 is connected to the top interface module 6. The atomizing nozzle assembly is a closed sprinkler head of the prior art. The nozzle is sealed by a heat-sensitive element (glass bulb or fusible alloy). The heat-sensitive element contains an organic solution with a high coefficient of expansion. When the ambient temperature reaches a set threshold (e.g., 68°C for red nozzles and 79°C for yellow nozzles), the liquid inside the glass bulb expands to the point of rupture, or the fusible alloy melts. This process triggers a seal failure, releases the pipeline pressure, and the water pressure pushes the nozzle open, thereby spraying water for fire extinguishing.

[0033] Since the fire sprinkler terminal 7 is generally trouble-free and rarely malfunctions, the tests described in this article mainly refer to checking whether there is water in the fluid supply module and water supply pipeline 2, to see if the pipeline is working properly or whether there is water. Therefore, when pipeline testing is required, the fire sprinkler terminal 7 needs to be removed, and then the diversion test terminal 8 is installed on the top interface module 6. In this embodiment, the diversion test terminal 8 includes a diversion valve 801 and its connected flexible diversion pipe 802. The detachable structure is a threaded connection structure or a snap-fit ​​connection structure. For example, Figure 5 As shown, the snap-fit ​​connection structure includes an outer groove 601 circumferentially arranged on the top interface module 6, and an inner groove 10 formed on the inner wall of the fire sprinkler terminal 7 and the flow guide valve 801. The inner groove 10 is provided with a ball bearing 11. The opening of the inner groove 10 is smaller than the diameter of the ball bearing 11, so the ball bearing 11 will not fall off. In this embodiment, the parts of the fire sprinkler terminal 7 and the flow guide valve 801 corresponding to the inner groove 10 are made of plastic material. Therefore, they can undergo a certain deformation under force during installation or disassembly, similar to the structure and installation and disassembly method of the water stop valve used in washing machines. Therefore, when the fire sprinkler terminal 7 or the flow guide valve 801 is installed on the top interface module 6, the ball bearing 11 is finally embedded into the outer groove 601 for fixation.

[0034] It also includes a water collection device 9, with the end of the flexible drainage pipe 802 extending to the water collection device 9. Therefore, when water is supplied to the water supply pipeline 2, the water coming out of the top interface module 6 will flow to the water collection device 9 through the guide valve 801 and the flexible drainage pipe 802. The water collection device 9 is generally placed on the ground of the hyperbaric oxygen chamber 5 without needing to be lifted, thus avoiding the test water from spraying everywhere and achieving the effect of orderly collection, reducing labor intensity.

[0035] Furthermore, a sealing component is provided inside the flow guide valve 801 to enhance the sealing performance between the flow guide valve 801 and the top interface module 6. The sealing component is a sealing ring made of fluororubber, located inside the flow guide valve 801. When the flow guide valve 801 is installed on the top interface module 6, the sealing ring can seal the connection between the flow guide valve 801 and the top interface module 6, preventing test water from seeping in. The flow guide valve 801 is provided with a hanging lug 8011 for easy removal and hanging. A flow meter 12 is also installed on the water supply pipeline 2 to facilitate timely monitoring of the water flow in the water supply pipeline 2 by the operator.

[0036] This utility model discloses a detachable hyperbaric oxygen chamber spray test device equipped with a chamber top interface module. The chamber top interface module can be detachably connected to either a fire sprinkler terminal or a diversion test terminal. The diversion test terminal includes a diversion valve and a connected flexible diversion pipe. When it is necessary to test the pipeline, the fire sprinkler terminal can be disassembled and the diversion test terminal can be installed. This allows the test water coming out of the pipeline to be collected, achieving directional collection of the test water. This effectively avoids the environmental interference caused by water diffusion in traditional tests, eliminates the need for personnel to lift the water, and reduces labor costs.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
