[0023] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0024] The logistics shaft system has a vertical shaft, which is the key transportation channel in the entire logistics shaft system. In addition, the shaft is usually located close to the department or department with transportation needs, and is connected to the horizontal transmission system, so that the logistics flow path is reasonably planned. However, due to the through-hole characteristics of the shaft, once a fire occurs, the fire and smoke may spread rapidly along the shaft. Therefore, the present invention provides a firewall structure for a hospital logistics shaft, which can quickly prevent the spread of fire when a fire occurs by arranging a corresponding firewall structure in the vertical shaft. It should be noted that in order to improve the fireproof performance of the entire logistics shaft system, the firewall structure disclosed in the present invention can be correspondingly arranged in multiple places in the shaft to further improve the fireproof effect.
[0025] Reference below Figure 1-Figure 5 A firewall structure of a hospital logistics shaft according to an embodiment of the present invention is described.
[0026] Reference Figure 1-Figure 5The present invention provides a fire wall structure of a hospital logistics shaft, including: a wall 1, a fireproof board 2, and a limiter 3. Four walls 1 are arranged to form a shaft 100. An inner wall of the shaft 100 is formed with a receiving groove 11. A track 200 for transporting medical supplies is arranged in the shaft 100. In this embodiment, some structures of the vertically arranged shaft 100 are improved. It can be understood that the track 200 should be arranged along the structure of the shaft 100, and the track 200 in the vertically arranged shaft 100 is also in a vertical state. Usually, the logistics shaft 100 system uses a turnover box as a carrier, and the turnover box moves along the track 200, thereby transporting the medical supplies loaded in the turnover box to the required location. The shaft 100 is composed of four walls 1, which have four inner side walls. It is usually necessary to set the track 200 near one of the side walls, that is, the track 200 is close to one of the walls 1, so as to facilitate the movement of the turnover box. At the same time, the fire wall structure is set in the wall 1 corresponding to the wall 1 to avoid affecting the transmission of medical supplies. The fireproof board 2 is a rectangular plate structure with fireproof performance. The lower edge of the fireproof board 2 is hinged to the bottom of the receiving groove 11 and can be turned toward the shaft 100. When the fireproof board 2 is rotated 90°, the side of the fireproof board 2 away from the receiving groove 11 stops at the bottom of the receiving groove 11, so that the fireproof board 2 is turned from a state parallel to the track 200 to a state perpendicular to the track 200, and the shaft 100 is closed to prevent the fire or smoke from spreading further. The fireproof board 2 is provided with a notch 21 for avoiding the track 200 in the well 100. After the fireproof board 2 is turned over, the notch 21 can avoid interfering with the track 200, and the well 100 is successfully closed. The stopper 3 is configured to detachably connect the upper edge of the fireproof board 2 and the wall 1. After the stopper 3 releases the connection between the fireproof board 2 and the wall 1, the fireproof board 2 is turned over to close the well 100.
[0027] In some specific embodiments, the notch 21 is formed at the upper edge of the fireproof board 2. Specifically, the edge of the fireproof board 2 connected to the receiving groove 11 in the normal state is defined as the lower edge of the fireproof board 2, and the side opposite to the lower edge of the fireproof board 2 is the upper edge of the fireproof board 2. The notch 21 has two first side walls arranged opposite to each other and a second side wall connecting the two first side walls. After the fireproof board 2 is turned over, the track 200 is inserted into the notch 21, and the second side wall corresponds to the side of the track 200 close to the receiving groove 11. A first sealing plate 22 is hinged at the first side wall, and a second sealing plate 23 is hinged at a second side wall. When the fireproof board 2 flips toward the track 200, after the upper edge of the fireproof board 2 abuts against the side of the track 200 close to the receiving groove 11, the second sealing plate 23 is squeezed to flip toward the side of the notch 21, so that the notch 21 is opened. When the fireproof board 2 continues to flip, the second sealing plate 23 abuts against the track 200, and the track 200 squeezes the second sealing plate 23, so that the second sealing plate 23 flips toward the side away from the track 200. After the fireproof board 2 is completely flipped, the four sides of the fireproof board 2 abut against the inner wall of the well 100, and one side of the first sealing plate 22 abuts against the side of the track 200 close to the receiving groove 11. The second sealing plate 23 covers the notch 21 and is located on the side of the track 200 away from the receiving groove 11. The notch 21 is sealed by the second sealing plate 23 to further improve the fireproof effect. After the need for fire protection disappears, the first sealing plate 22 and the second sealing plate 23 can be manually flipped over so that the notch 21 is opened and the fire protection plate 2 can be separated from the track 200 to restore the initial daily state.
[0028] The fireproof board 2 has two positions, namely, the non-failed position and the released position. When the fireproof board 2 is in the non-failed position, it is the state under normal circumstances, and the fireproof board 2 is located in the receiving groove 11, and the side of the fireproof board 2 close to the well 100 is flush with the inner wall of the wall on which the fireproof board 2 is installed; when the fireproof board 2 is in the released position, it is the state where the temperature in the well is high and there may be signs of fire, the limiter 3 releases the connection between the fireproof board 2 and the wall 1, and the fireproof board 2 flips into the well 100 and seals the well 100. Under normal circumstances, the fireproof board 2 is restricted by the limiter 3 so that the fireproof board 2 is located on one side of the shaft 100 and does not hinder the transportation of medical supplies in the shaft 100; when the temperature in the shaft 100 rises, the limiter 3 releases the restriction on the fireproof board 2 so that the fireproof board 2 is flipped into the shaft 100 to seal and cut off the shaft 100, preventing the fire or smoke from further extending to the top of the shaft 100. In this way, the convenience of daily logistics transmission can be met, and the spread of fire and smoke can be quickly and effectively blocked when a fire occurs, thereby improving the fire safety of the hospital logistics shaft system.
[0029] Reference Figure 1 and Figure 2According to some embodiments of the present invention, the limiting member 3 includes: two connecting parts 31, a limiting strip 32 and a pushing spring 33. One connecting part 31 is arranged on the inner side wall of the shaft 100 and is located above the receiving groove 11. The other connecting part 31 is arranged on one side of the fireproof board 2 and is aligned with the connecting part 31 located above. Both connecting parts 31 are provided with vertical perforations. One end of the limiting strip 32 is inserted into the perforation of the upper connecting part 31, and the other end of the limiting strip 32 is inserted into the perforation of the lower connecting part 31. The limiting strip 32 is configured to deform after reaching a preset temperature. The two ends of the pushing spring 33 are respectively stopped by the limiting strip 32 and the inner side wall of the wall 1, and the pushing spring 33 is configured as a compression spring. The width of the perforation is much larger than the thickness of the end of the limiting strip 32, so that the limiting strip 32 can be easily separated from the perforation after being deformed by heat. The limiting member 3 is a temperature-sensitive automatic release structure, which automatically closes the fireproof board 2 to close the shaft 100 in the event of a fire. In this embodiment, two upper and lower connecting parts 31 are provided, and the limit strip 32 is inserted into the perforations of the two connecting parts 31, so that the fireproof board 2 can be located in the receiving groove 11 and on one side of the track 200 under normal conditions, and will not affect the turnover box of the track 200 to transport medical supplies. Under normal conditions, the pressure of the push spring 33 acts on the limit strip 32, so that it maintains a stable position, thereby ensuring that the fireproof board 2 remains open. When the limit strip 32 is deformed at high temperature, the force of the push spring 33 will push the limit strip 32 to move or deform, thereby promoting the release of the fireproof board 2. Specifically, the limit strip 32 can be a shape memory alloy or a low melting point alloy, a thermoplastic material or a high temperature sensitive composite material, etc., as long as its thermal response characteristics are ensured to match the fire protection requirements of the shaft 100, so as to ensure that the flipping action of the fireproof board 2 can be triggered in a timely and reliable manner in the event of a fire.
[0030] Reference Figure 1 , Figure 5 According to some embodiments of the present invention, two gas springs 34 are arranged in parallel and tilted in the receiving groove 11, the fixed ends of the two gas springs 34 are hinged to the groove wall of the receiving groove 11, and the extended ends of the two gas springs 34 are hinged to one side of the fireproof board 2 and close to the lower edge of the fireproof board 2. After the limiter 3 releases the restriction on the fireproof board 2, the fireproof board 2 can be better released and turned over with the assistance of the two gas springs 34, thereby completing the sealing of the well 100.
[0031] Reference Figure 3 , Figure 5 According to some embodiments of the present invention, a fire extinguishing gas cylinder 4 is provided on the groove wall of the receiving groove 11 opposite to the fireproof board 2, and the fireproof board 2 is provided with a starting member 5 for opening the fire extinguishing gas cylinder 4. By arranging the fire extinguishing gas cylinder 4 in the receiving groove 11, the fire prevention effect of the well 100 can be further improved.
[0032] Reference Figure 3According to some embodiments of the present invention, the starting member 5 includes: a latch 51 and a connecting rope 52, the latch 51 is inserted into the opening of the gas cylinder, the two ends of the connecting rope 52 are respectively connected to the latch 51 and the fireproof board 2, and the tension of the connecting rope 52 is less than the elastic force of the push spring 33.
[0033] The fireproof board 2 and the plug 51 blocking the fire extinguishing gas cylinder 4 are connected by a connecting rope 52. After the fireproof board 2 is released, the plug 51 can be pulled out to automatically start the fire extinguishing gas cylinder 4. The plug 51 is a safety pin on the fire extinguishing gas cylinder 4. It can be automatically started to spray and extinguish the fire by pulling it out before use. It should be noted that the opening of the fire extinguishing gas cylinder 4 faces downward, and the connecting rope 52 has a certain elastic force, which is convenient for connecting the plug 51 to the fireproof board 2 through the connecting rope 52. Moreover, when the fireproof board 2 is turned over to a certain extent, the connecting rope 52 is tightened, thereby pulling and pulling out the plug 51.
[0034] Reference Figure 3 , Figure 5 According to some embodiments of the present invention, a receiving cavity 12 is provided in the wall 1 and above the receiving groove 11, a material guide port 14 for filling flame-retardant filler is provided on one side of the receiving cavity 12, and a connecting channel 13 is provided between the receiving cavity 12 and the receiving groove 11.
[0035] The flame retardant filler is filled into the accommodating cavity 12 from the material guide port 14, and is transported to the accommodating groove 11 through the connecting channel 13. As the fireproof board 2 is flipped into the well 100, the notch of the accommodating groove 11 is opened, and the flame retardant filler can be input into the well 100 from the notch of the accommodating groove 11. The flame retardant filler can effectively improve the fire prevention effect in the well 100.
[0036] Reference Figure 3 According to some embodiments of the present invention, the connecting passage 13 is inclined from bottom to top toward a side away from the well 100. The inclined connecting passage 13 can guide the flame retardant filler to a position close to the notch of the receiving groove 11, thereby reducing the accumulation of the flame retardant filler in the receiving groove 11.
[0037] Reference Figure 3 , Figure 4 According to some embodiments of the present invention, a blocking plate 15 is hingedly connected to the top of the receiving groove 11, and a torsion spring is provided on the hinge shaft of the blocking plate 15 for driving the blocking plate 15 to seal the connecting passage 13. Through the use of the blocking plate 15 and the torsion spring, when the flame retardant filler in the receiving cavity 12 reaches a certain weight and the fireproof plate 2 is opened, the blocking plate 15 can be turned over by overcoming the elastic force of the torsion spring under the pressure of the weight of the flame retardant filler, so as to open the connecting passage 13 and convey the flame retardant filler.
[0038] In some specific examples, a stop block 16 is provided on one side of the fireproof board 2 close to the receiving groove 11, and the side of the stop block 16 facing away from the fireproof board 2 is an arc surface, and the arc surface can stop against the lower end surface of the blocking plate 15, thereby ensuring that the blocking plate 15 is in a state of sealing the connection channel 13. In this way, sufficient flame-retardant filler can be filled in the receiving chamber 12 in advance, so that the gravity of the flame-retardant filler is greater than the elastic force of the torsion spring, and then after the fireproof board 2 is opened, the blocking plate 15 can be automatically opened to transport the flame-retardant filler into the shaft 100. Specifically, the stop block 16 can be made of rubber material, so that when the fireproof board 2 is turned over, the arc surface and the deformable performance of the rubber material enable the fireproof board 2 to be smoothly turned into the shaft 100.
[0039] Reference Figure 3 According to some embodiments of the present invention, a sealing opening 17 is provided on the side of the receiving groove 11 facing away from the fireproof board 2 , and a sealing cover 18 is detachably provided in the sealing opening 17 .
[0040] By opening the sealing opening 17 outside the well 100, it is convenient to construct the fire wall structure, and a clamp can be fixed on the inner side of the sealing cover 18, the opening of the clamp faces the side of the fireproof board 2, and the fire extinguishing gas cylinder 4 can be smoothly clamped on the sealing cover 18 through the clamp. In addition, two groups of clamps can be arranged at intervals along the height direction of the sealing cover 18, the length of the clamp located at the top extending from the side connected to the sealing cover 18 to the side away from the sealing cover 18 is a1, and the length of the clamp located at the bottom extending from the side connected to the sealing cover 18 to the side away from the sealing cover 18 is a2, a1 is less than a2, so that the fire extinguishing gas cylinder 4 can be installed obliquely on the inner side of the sealing cover 18. When the fireproof board 2 is turned over into the well 100, since the lower end of the fire extinguishing gas cylinder 4 is tilted toward the well 100, the effect of the connecting rope 52 pulling the pin 51 can be improved, thereby ensuring that the fire extinguishing gas cylinder 4 can be smoothly started after the fireproof board 2 is turned over.
[0041] Reference Figure 1-Figure 5 The present invention also proposes a construction process for a firewall structure of a hospital logistics shaft, which is used to construct a firewall structure of a hospital logistics shaft as in any of the above embodiments. The construction process includes the following steps: S1. The inner wall of the wall 1 enclosing the shaft 100 is coated with fireproof material, and the rail 200 located in the shaft 100 is also coated with fireproof material as much as possible to improve the overall fireproof performance.
[0042] S2. A sealing opening 17 is opened on one side of the wall 1 opposite to the track 200 set in the shaft 100, a receiving groove 11 is opened along the sealing opening 17, and a receiving cavity 12 is opened on the wall 1 above the receiving groove 11, and a connecting passage 13 is excavated between the receiving cavity 12 and the receiving groove 11. The connecting passage 13 is inclined from top to bottom toward the shaft 100, and the lower end of the connecting passage 13 is close to the notch of the receiving groove 11. A material guide opening 14 is opened on the outside of the receiving cavity 12, that is, on the side of the receiving cavity 12 away from the shaft 100, and a material guide part can be rotatably installed at the material guide opening 14, so that the flame retardant filler can be input from the material guide opening 14 into the receiving cavity 12 through the material guide part, and then input into the receiving groove 11 through the connecting passage 13, so that the flame retardant filler can fall into the shaft 100, thereby enhancing the fire prevention effect in the shaft 100.
[0043] S3, assemble the fireproof board 2, and hinge the lower edge of the fireproof board 2 to the bottom of the receiving groove 11, hinge the two ends of the gas spring 34 to the fireproof board 2 and the groove wall of the receiving groove 11, and rotate the fireproof board 2 into the receiving groove 11, so that the fireproof board 2 and the track 200 are parallel to each other, and the side of the fireproof board 2 close to the well 100 is flush with the inner wall of the well 100. Then insert the limit strip 32 between the two connecting parts 31 and make the two ends of the push spring 33 stop against the inner wall of the well 100 and the limit strip 32, and finally install the sealing cover 18 from the outside of the receiving groove 11 to seal the receiving groove 11.
[0044] After the above structure is installed, if the temperature in the shaft 100 is too high, the limiter 3 will automatically deform, so that the fireproof board 2 is released and turned over, and the shaft 100 is sealed to prevent the fire or smoke from spreading upward. It should be noted that a smoke alarm or other sensor can be installed in the shaft 100 to quickly detect whether there are signs of fire in the shaft 100. When signs of fire are detected, if the fireproof board 2 has not turned over to seal the shaft 100, the fireproof board 2 can be released by manually removing the limit of the limit strip 32 to ensure the safety of the shaft 100.
