Technical Field

[0001] This utility model relates to the field of refuge device technology, specifically a refuge device for safety in chemical production. Background Technology

[0002] Chemical industrial parks, as a mainstream development model of the chemical industry, represent a new approach to chemical industry development in my country in recent years. As hubs for chemical plants, these parks, while promoting local economic development, also pose significant safety hazards. The enterprises within these parks are diverse, involving a wide variety of chemicals, most of which are flammable, explosive, toxic, or hazardous. Furthermore, the large population density and high number of workers within these parks mean that any explosion or other safety accident could have extremely serious consequences.

[0003] According to the public announcement (CN214835223U), a refuge device for chemical production safety is disclosed. This technology discloses "including walls and floors, with two frames symmetrically fixedly connected to both sides of the walls. The frames are semi-frustum-shaped, and the frames have openings near the walls. The inner side of the frames corresponding to the openings is equipped with barrier doors, etc. This technology has the technical effect that workers can decisively run to the exit in the event of an explosion, and can enter the device for refuge even if the outer exit is buried."

[0004] While the above design allows workers to quickly run to the exit during an explosion, and even if the outer exit is buried, they can still enter the device for refuge, the temperature inside the refuge chamber can rise rapidly if a fire breaks out due to the explosion. This can cause a sharp increase in the internal temperature of the refuge chamber, making the environment inside the chamber harsher and putting the refugees in a more dangerous situation, threatening their safety. Therefore, we propose a refuge device for chemical production safety to solve the above-mentioned problems. Utility Model Content

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown:

[0025] A refuge device for safety in chemical production includes a base plate 1, a wall 2 fixed to the upper surface of the base plate 1, and refuge chambers 3 fixedly installed on both sides of the wall 2.

[0026] In this implementation plan: The existing device {publication (announcement) number}: CN214835223U discloses a refuge device for chemical production safety. This application further improves upon this existing device, as detailed in the following disclosure. To solve the technical problems existing in this prior art, such as the background art disclosed above, "When the above design is in use, although the staff can decisively run to the exit position when an explosion occurs, and can enter the device for refuge even if the outer exit is buried, when the staff are in refuge chamber 3, if a fire occurs due to the explosion, the temperature will rise rapidly, which can easily lead to a sharp rise in the internal temperature of refuge chamber 3, making the internal environment of refuge chamber 3 harsh, putting the refugees in a more dangerous situation, and threatening the safety of the refugees." In combination with the use, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, a cooling component 4 has been added to this application. All electrical equipment involved in this product is powered by an external power source.

[0027] Furthermore:

[0028] like Figures 1-4 As shown:

[0029] A cooling component 4 is installed on the refuge chamber 3. The cooling component 4 includes a water pump 402 disposed between the two sets of refuge chambers 3, a connecting pipe 404 disposed at the output end of the water pump 402, and a connecting pipe 405 fixedly connected to both ends of the connecting pipe 404.

[0030] L-shaped pipes 406 are fixedly installed at both ends of the connecting pipe 405. The two sets of L-shaped pipes 406 located on the same side of the wall 2 are fixedly connected to the same set of arc-shaped pipes 407 with sealed ends. Multiple sets of equally spaced drainage heads are fixedly connected to the lower surface of the arc-shaped pipes 407.

[0031] An external water supply pipe 410 is installed on the upper surface of the base plate 1. A connecting pipe 411 is fixed to the water delivery end of the external water supply pipe 410. A water tank 412 is fixed to the upper surface of the base plate 1. One end of the connecting pipe 411 is fixedly connected to one side of the water tank 412. A control valve 413 is installed inside the connecting pipe 411. A delivery pipe 409 is fixed to the input end of the water pump 402. The other end of the delivery pipe 409 is fixedly connected to the water tank 412.

[0032] One end of the delivery pipe 409 passes through the outside of the water tank 412 and extends to the bottom of the inner cavity of the water tank 412. A rectangular hole is opened on the surface of the wall 2 near the water pump 402, and a mounting plate 401 is installed in the rectangular hole. The two sides of the mounting plate 401 are fixedly connected to the inner side walls of the two sets of refuge chambers 3 respectively. The water pump 402 is fixedly installed on the upper surface of the mounting plate 401 by bolts.

[0033] In this implementation plan: When workers enter the refuge chamber 3 for emergency refuge, and a fire breaks out in the chemical production workshop due to an explosion, the control valve 413 is opened, releasing the blockage on the connecting pipe 411. Water from the external water supply pipe 410 then flows through the connecting pipe 411 into the water tank 412. Simultaneously, the water pump 402 is activated, drawing water from the water tank 412 through the delivery pipe 409 and delivering it to the connecting pipe 404. Connecting pipe 404 delivers water to connecting pipe 405 and L-shaped pipe 406. Water from inside L-shaped pipe 406 then enters arc-shaped pipe 407 and is discharged through the drain head of arc-shaped pipe 407. The discharged water falls on the surface of refuge chamber 3 to cool it down. This reduces the surface temperature of refuge chamber 3, decreases heat transfer into refuge chamber 3, creates a relatively cool environment for evacuees, and to some extent prevents flames from directly contacting refuge chamber 3, slows the spread of fire to the refuge chamber, increases evacuation time, and improves the effectiveness of the device.

[0034] It should be noted that the external water supply pipe 410 is connected to the external water supply system to maintain the water supply effect at all times.

[0035] Furthermore;

[0036] In an optional embodiment, a baffle 414 is provided above the arc-shaped tube 407, and the baffle 414 is fixed to the surface of the wall 2.

[0037] In this embodiment: During this process, the baffle 414 can protect the arc-shaped tube 407 and prevent falling debris from hitting the arc-shaped tube 407 and causing damage.

[0038] Furthermore;

[0039] In an optional embodiment, a fixing plate 415 is fixed to the surface of the L-shaped tube 406, and a spring 416 is sleeved on the surface of the L-shaped tube 406. The two ends of the spring 416 are fixedly connected to the fixing plate 415 and the refuge chamber 3, respectively. A sliding hole adapted to the L-shaped tube 406 is opened on the surface of the refuge chamber 3. The L-shaped tube 406 and the refuge chamber 3 are slidably connected through this sliding hole. A hose 403 is fixedly installed between the output end of the water pump 402 and the connecting pipe 404.

[0040] In this embodiment: when the baffle 414 is damaged by the impact of the stone, when the baffle 414 collides with the arc-shaped tube 407, the arc-shaped tube 407 drives the L-shaped tube 406 to slide through the sliding hole opened in the refuge chamber 3. At the same time, the L-shaped tube 406 is compressed by the spring 416 driven by the fixed plate 415. The spring 416 can buffer the impact of the arc-shaped tube 407, and can buffer the impact force on the arc-shaped tube 407, further improving the protective effect of the arc-shaped tube 407 and the L-shaped tube 406. The flexible hose 403 can be flexibly bent, so as not to affect the effect of the L-shaped tube 406 driving the connecting pipe 2 405 and the connecting pipe 1 404 to move downward.

[0041] Furthermore;

[0042] In an optional embodiment, a backup battery 408 is fixedly installed on the upper surface of the mounting plate 401, and the backup battery 408 is used to power the water pump 402.

[0043] In this embodiment: when the external power source is damaged by an explosion, the water pump 402 can be powered by the backup battery 408.

[0044] It should be noted that the backup battery 408 is rechargeable.

[0045] The working principle and usage process of this utility model: This refuge device, used for safety in chemical production, allows workers to enter the refuge chamber 3 for emergency refuge. If a fire breaks out in the chemical production workshop due to an explosion, the control valve 413 is opened, releasing the blockage on the connecting pipe 411. Water from the external water supply pipe 410 then flows through the connecting pipe 411 into the water tank 412. Simultaneously, the water pump 402 is activated, drawing water from the water tank 412 through the delivery pipe 409 and delivering it to the connecting pipe 404. From there, the water is delivered to the connecting pipe 405 and the L-shaped pipe 406. Water from the L-shaped pipe 406 then flows into the arc-shaped pipe 407 and is discharged through the drain head. The discharged water falls onto the surface of the refuge chamber 3, cooling it down and reducing heat transfer into the chamber, creating a relatively cool environment for the refugees and mitigating the risk of fire. To prevent direct contact between the flames and the refuge chamber 3, the fire spreads to the refuge chamber at a slower pace, increasing refuge time and improving the effectiveness of the device. During this process, the baffle 414 protects the arc-shaped tube 407 from damage caused by falling debris. When the baffle 414 is damaged by impact from stones, and when it collides with the arc-shaped tube 407, the arc-shaped tube 407 causes the L-shaped tube 406 to slide through the sliding hole in the refuge chamber 3. Simultaneously, the L-shaped tube 406 compresses the spring 416 via the fixed plate 415. The spring 416 acts as a buffer when the arc-shaped tube 407 is impacted, thus reducing the impact force and further improving the protection of the arc-shaped tube 407 and the L-shaped tube 406. The flexible hose 403 allows for flexible bending without affecting the downward movement of the L-shaped tube 406, which drives the connecting tube 2 405 and the connecting tube 1 404.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
