Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cold storage smoke exhaust, in particular to a smoke exhaust device for a cold storage. Background Art
[0002] In order to improve fire safety, smoke exhaust openings are usually arranged at the top of the cold storage. When a fire occurs in the cold storage, the smoke exhaust openings are opened to discharge smoke. The number and positions of the smoke exhaust openings in the cold storage are determined according to the actual area of the warehouse and the smoke exhaust zones.
[0003] In the related art, a switchable smoke exhaust door is arranged at the smoke exhaust opening, and the smoke exhaust door is rotatably connected to the roof. The smoke exhaust door is closed by an electric lock, and the electric lock unlocks after receiving an opening signal, and the smoke exhaust door automatically opens under the action of gravity. When it is necessary to close after the smoke exhaust is completed, workers still need to climb onto the roof to manually close the smoke exhaust door. This kind of rotatable opening and closing smoke exhaust door is inconvenient to use. Moreover, a relatively large rotating space needs to be vacated below the rotatably arranged smoke exhaust door. Usually, when the cold storage is in use, it is easy to overlook the possible fire problem in the cold storage. When stacking items in the cold storage, even if they encounter the smoke exhaust door, it is not easy to think of vacating a rotating space below it, resulting in the items blocking the smoke exhaust door when stacked, making it difficult to open the smoke exhaust door.
[0004] Some solutions in the prior art also mention a push-pull smoke exhaust door, which uses the inclined surface cooperation between the door body and the fixed frame to achieve sealing. However, this solution that only relies on the inclined surface cooperation to reduce the outflow of cold air is feasible during normal use. When a fire occurs in the cold storage and the smoke exhaust door is opened once, the inclined surface is deformed by heat, resulting in the smoke exhaust door being unable to move to the fully closed position after the smoke exhaust is completed, so that the reuse rate of this kind of smoke exhaust door is not high.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0038] Next, refer to Figures 1 - 5 Describe the smoke exhaust device 100 of the cold storage according to an embodiment of the present utility model.
[0039] As Figures 3 - 4 shown, the smoke exhaust device 100 of the cold storage according to an embodiment of the present utility model can be installed at the smoke exhaust port 200 of the cold storage.
[0040] As Figures 1 - 5 shown, the smoke exhaust device 100 includes a track member 1, a door body 2, a driving member 3, and a controller 7.
[0041] The installation quantity of the track member 1 is not limited, and it is located at the smoke exhaust port 200. AsFigure 3 and Figure 4 As shown in Figure 4 , there may be two track members 1. The two track members 1 include a first track member 1a and a second track member 1b. The first track member 1a and the second track member 1b are installed on opposite sides of the smoke exhaust port 200. Please refer to Figure 5 , the door body 2 is a heat-insulating body. Sliding members 21 are respectively installed at both ends of the door body 2. The sliding members 21 at both ends are respectively engaged with the two track members 1, so that the door body 2 can slide along the track members 1. The door body 2 has a closed position for closing the smoke exhaust port 200 and an open position for opening the smoke exhaust port 200. It can be understood that when in the closed position, the door body 2 completely closes the smoke exhaust port 200. When in the open position, the specific position of the door body 2 is not limited, as long as the smoke in the cold storage can be discharged from the smoke exhaust port 200.
[0042] Of course, in this application, it is not excluded that in some embodiments, there is only one track member 1, and the sliding member 21 on the door body 2 cooperates with the track member 1, which can also guide the door body 2 to translate and switch between the closed position and the open position.
[0043] The door body 2 is a heat-insulating door. The door body 2 can close the smoke exhaust port 200, thereby reducing the problem of cold loss caused by the smoke exhaust port 200 and reducing the energy consumption of the cold storage. It can be understood that after the cold storage is used, the temperature inside the cold storage is usually lower than the temperature outside the cold storage. If the door body 2 is an ordinary door without heat insulation, the door body 2 will have a lower temperature affected by the cold air inside the cold storage. The water vapor in the warm air outside the smoke exhaust port 200 will form condensed water when it meets the cold door body 2, and the condensed water will flow along the door body 2 to the edge and drip downward. In this application, by setting the door body 2 as a heat-insulating door, the surface temperature of the side of the door body 2 facing the inside of the cold storage is not much different from the temperature of the cold air inside the cold storage, and the surface temperature of the side of the door body 2 facing the smoke exhaust port 200 is not much different from the temperature of the warm air outside the cold storage, reducing the generation of condensed water on the door body 2 and reducing the probability of dripping water from the door body 2.
[0044] In the prior art of traditional smoke exhaust doors, the door body is rotatably connected to the smoke exhaust port through a hinge. In order to keep the door body closed at the closed position for a long time when the door body closes the smoke exhaust port, an electromagnetic suction structure is usually set at the smoke exhaust port to suck and hold the door body at the closed position. However, in the case of power failure or unstable current, the electromagnetic suction structure may not be able to adsorb the door body, and the door body will open the smoke exhaust port under the action of its own gravity. In this application, the door body 2 slides along the track member 1, can close or open the smoke exhaust port 200, and the door body 2 is held at the closed position or the open position through the track member 1. There is no need to set an electromagnetic suction structure, which is convenient for the door body 2 to open and close, and reduces the probability of the door body 2 automatically opening when the power is off or the power supply is unstable, improving the effectiveness and reliability of the smoke exhaust device 100 for heat preservation of the cold storage.
[0045] In the prior art, there are also smoke exhaust doors that are horizontally slidably arranged, and the inclined surfaces on the frame are used for sealing to reduce cold air loss. However, they are prone to jamming and have a low reuse rate. In contrast, in this application, the heat preservation characteristics of the door body 2 are utilized. After the door body 2 is repeatedly used and used in a high-temperature environment, it still has heat preservation characteristics, so it can be repeatedly used.
[0046] It should be further pointed out that generally, the size of the door body 2 is larger than the size of the smoke exhaust port 200, which can improve the effectiveness of the door body 2 in closing the smoke exhaust port 200 and at the same time improve the heat preservation effect of the door body 2.
[0047] The driving member 3 is connected to the door body 2 to drive the door body 2 to slide. The controller 7 is electrically connected to the driving member 3 to control the operation of the driving member 3. That is to say, the controller 7 is connected to the driving member 3. When a fire occurs or smoke is detected in the cold storage and the smoke in the cold storage needs to be discharged, the driving member 3 drives the door body 2 to slide to the open position, and the smoke is discharged through the smoke exhaust port 200. When it is determined that the cold storage returns to normal, the driving member 3 drives the door body 2 to slide to the closed position, and the smoke exhaust port 200 is closed. Of course, it is not excluded that in some solutions, when it is determined that the cold storage returns to normal, workers can climb to the device and manually drive the door body 2 to slide to the closed position to also close the smoke exhaust port 200.
[0048] According to the smoke exhaust device 100 of the embodiment of the present invention, the door body 2 is a heat preservation door. When the door body 2 is in the closed position, the door body 2 can reduce the leakage of cold air from the cold storage and reduce the energy consumption of the cold storage. The door body 2 itself has heat preservation properties. Compared with other heat preservation solutions, this door body 2 of this application can be repeatedly used with a high utilization rate. At the same time, the setting of the heat preservation door is beneficial to reducing the amount of condensed water generated on the door body 2 and reducing the probability of water dripping down from the door body 2. The door body 2 cooperates with the track member 1 to achieve translational switching between the closed position and the open position. The opening and closing action of the door body 2 is controlled by the driving member 3, making the opening and closing of the door body 2 very convenient. There is no need to reserve a rotating space for the door body 2, and the door body 2 is not easily stuck by the items piled up in the cold storage, improving the use reliability of the smoke exhaust device 100.
[0049] Exemplarily, as Figures 1 - 2 shown, one end of the smoke exhaust pipe 300 is communicated with the smoke exhaust port 200, and the other end is communicated with the external space of the cold storage. A fan can also be arranged inside the smoke exhaust pipe 300 to drive the smoke in the cold storage to be discharged outside the cold storage. The smoke exhaust port 200 is arranged on the wall surface 400 of the cold storage, and the wall surface 400 here can be the side wall surface of the cold storage or the top wall surface of the cold storage.
[0050] Specifically, an elastic sealing gasket can also be arranged on the door body 2. When the door body 2 is in the closed position, the elastic sealing gasket is located at the gap between the door body 2 and the wall surface 400, further enhancing the sealing effect of the door body 2 on the smoke exhaust port 200.
[0051] As Figure 5 shown, in some embodiments, the sliding member 21 is a slider or a roller. Optionally, the sliding member 21 may be a slider. There is a slideway in the track member 1, and the slider can be clamped in the slideway. The slider occupies a small space, making the structure of the smoke exhaust device 100 more compact. Optionally, the sliding member 21 may be a roller. At least part of the roller is wrapped in the slideway to prevent it from falling off. The roller rolls along the slideway to drive the door body 2 to translate, which can make the movement of the door body 2 smoother.
[0052] As Figures 1 - 2 shown, in some embodiments, the smoke exhaust device 100 of the cold storage further includes a limiting member 4. The limiting member 4 can stop the door body 2 at the closed position. The limiting member 4 helps to prevent the door body 2 from translating too far and being unable to close the smoke exhaust port 200. That is, the limiting member 4 can limit the door body 2 at the closed position, thereby improving the reliability and effectiveness of the heat preservation of the door body 2.
[0053] In some specific examples, one of the limiting member 4 and the door body 2 has a signal detection member (not shown in the figure). When the door body 2 abuts against the limiting member 4, the electrical signal of the signal detection member changes and is fed back to the controller 7, and the controller 7 controls the driving member 3 to stop driving. In some solutions, the above purpose can also be achieved without setting the signal detection member. Specifically, when the driving member 3 drives the door body 2 to move, its output current will fluctuate due to the change of the load. When the door body 2 abuts against the limiting member 4, the output current changes and is fed back to the controller 7, and the controller 7 can control the driving member 3 to stop driving. This method requires a high sensitivity for current detection.
[0054] As Figures 3 - 4 shown, specifically, the limiting member 4 is a stop block. The limiting member 4 is located between the two track members 1. The stop block is adapted to limit the door body 2 at the closed position.
[0055] In some specific embodiments, as Figure 2 shown, the limiting member 4 is provided with a locking portion 41. When the door body 2 is in the closed position, the locking portion 41 is stuck on the door body 2 to lock it. This can improve the sealing performance of the door body 2 in the closed position, reduce shaking, and reduce the loss of cold energy in the cold storage.
[0056] Specifically, as Figure 1 shown, the limiting member 4 is a stop block, and the end of the stop block forms a hook, which can be used as the locking portion 41 and hooked on the door body 2. The setting of the hook is beneficial to tightly close the door body 2 when the door body 2 is in the closed position. When the door needs to be opened, the driving member 3 pulls the door body 2 to move, and the hook is disengaged from the door body 2.
[0057] Of course, the structure of the locking part 41 in this application is not limited to this, and it can also be a magnetic part or the like. When the door body 2 is in the closed position, the locking part 41 is attracted to the door body 2 for locking. When the door needs to be opened, the driving part 3 pulls the door body 2 to move away from the locking part 41, and the suction force weakens after moving away.
[0058] As Figure 3 shown, in some embodiments, the smoke exhaust device 100 of the cold storage further includes a frame body 5, and the frame body 5 is installed around the smoke exhaust port 200. The track member 1 is installed on the frame body 5 or integrally formed on the frame body 5, and the door body 2 is located on one side of the frame body 5.
[0059] Taking the two track members 1 as an example, after the frame body 5 connects the two track members 1 to form a whole, the whole is fixed on the roof or the wall surface 400 of the wall during installation, and it is not necessary to install and position the two track members 1 separately, reducing the installation difficulty. Moreover, other components can also be fixed by means of the frame body 5, improving the overall integration degree.
[0060] To improve the sealing effect of the door body 2 when it is closed, in some embodiments, when the door body 2 is in the closed position, a first sealing contact surface is formed between the door body 2 and the frame body 5, and the first sealing contact surface is an annular surface surrounding the smoke exhaust port 200. That is to say, it is a surface contact between the door body 2 and the frame body 5, and the contact surface between the two in the closed position is called the first sealing contact surface, so that when the door body 2 is in the closed position, there is no gap between the door body 2 and the frame body 5, improving the sealing effect between the door body 2 and the frame body 5, which is beneficial to reducing the cold loss and improving the heat preservation effect. Optionally, the frame body 5 is a square frame, and the first sealing contact surface is a square ring.
[0061] In other embodiments, as Figure 3 shown, to improve the sealing effect of the door body 2 when it is closed, the smoke exhaust device 100 further includes a sealing convex ring 8 located inside the frame body 5. When the door body 2 is in the closed position, a second sealing contact surface is formed between the door body 2 and the sealing convex ring 8, and the second sealing contact surface is an annular surface surrounding the smoke exhaust port 200. That is to say, it is a surface contact between the door body 2 and the sealing convex ring 8, and the contact surface between the two in the closed position is called the second sealing contact surface, so that when the door body 2 is in the closed position, there is no gap between the door body 2 and the sealing convex ring 8, which is beneficial to reducing the cold loss and improving the heat preservation effect. Optionally, the shape of the sealing convex ring 8 is the same as that of the smoke exhaust port 200. For example Figure 3 in the example of , the smoke exhaust port 200 is a square port, the sealing convex ring 8 is a square ring, and the second sealing contact surface is a square ring. Of course, when the shape of the smoke exhaust port 200 changes, the shape of the sealing convex ring 8 can also be adjusted accordingly.
[0062] In some other embodiments, when the door body 2 is in the closed position, a first sealing contact surface is formed between the door body 2 and the frame body 5, and a second sealing contact surface is formed between the door body 2 and the sealing convex ring 8. In this way, when in the closed position, two annular sealing contact surfaces are formed between the edge of the door body 2 and the edge of the smoke exhaust port 200, providing a better sealing effect.
[0063] In some embodiments, the frame body 5 and the track member 1 are integrally formed metal parts. The metal parts have high reliability, will not become brittle at low temperatures, and are not easily deformed due to high temperatures during smoke exhaust. Moreover, since the frame body 5 and the track member 1 are integrally formed, their relative positions can be kept unchanged. Especially when the door body 2 slides along the track member 1 to the closed position and the above-mentioned sealing contact surfaces need to be formed, the reliability of the smoke exhaust device 100 in functioning can be improved.
[0064] As Figures 1 - 4 shown, in some embodiments, the driving member 3 is an electric push rod, and the electric push rod is arranged parallel to the track member 1. One end of the electric push rod is fixed on the wall surface 400 of the cold storage, and the other end of the electric push rod is connected to the driving connection member 22 of the door body 2. The electric push rod pushes the door body 2 to translate between the closed position and the open position. By arranging the electric push rod parallel to the track member 1, the moving path of the electric push rod, the extending direction of the track member 1, and the translation path of the door body 2 are all parallel. Thus, the door body 2 can move more smoothly, and the installation space required for the electric push rod is smaller.
[0065] In some embodiments, as Figure 2 shown, the controller 7 includes an automatic control member 71. The automatic control member 71 is electrically connected to the driving member 3. After judging the received detection signal, the automatic control member 71 controls the movement of the driving member 3. With such a setting, the automation of the opening and closing of the door body 2 is realized.
[0066] In some embodiments, as Figure 2 shown, the controller 7 further includes a manual control member 72, and the manual control member 72 is separately arranged from the door body 2. This is because the door body 2 needs to be installed at the smoke exhaust port 200, and the manual control member 72 needs to be installed at a position convenient for workers to operate.
[0067] Among them, the manual control member 72 is provided with a manual input part, and the manual control member 72 is electrically connected to the driving member 3 to control the operation of the driving member 3 according to the input information of the manual input part. The manual control member 72 can manually control the driving member 3. For example, when people visually observe and smell to judge that there is smoke in the cold storage and trigger the manual input part, they can also control the door body 2 in the cold storage to open the smoke exhaust port 200.
[0068] In some other embodiments, as Figure 2As shown, the controller 7 includes an automatic control component 71 and a manual control component 72, both of which can control the opening and closing of the door body 2, while having the advantages of both manual and automatic control.
[0069] When the controller 7 includes an automatic control component 71, that is, the controller 7 determines whether the door 2 needs to be opened or closed, the signal source required by the controller 7 can be provided by the smoke exhaust device 100 itself, or can come from outside, such as from a smoke alarm originally installed in the cold storage.
[0070] In some specific embodiments, Figure 1 As shown, the smoke exhaust device 100 further includes a sensor 6, which is a temperature sensor or a smoke sensor. The installation position of the sensor 6 is not limited.
[0071] Controller 7 includes an automatic control element 71, which is electrically connected to sensor 6 and driver 3, respectively, to control the operation of driver 3 based on the sensing results of sensor 6. When a fire occurs in the cold storage, the temperature sensor or smoke sensor sends a signal to automatic control element 71, which in turn controls the opening of driver 3. This means that when a fire occurs in the cold storage, the door 2 of smoke exhaust device 100 can automatically and promptly open and exhaust smoke based on detection by sensor 6, thereby minimizing losses and assisting firefighting efforts.
[0072] For example, there may be multiple sensing elements 6 distributed at multiple locations in the cold storage, thereby increasing the detection range of the sensing element 6. The electrical connection between the automatic control element 71 and the sensing element 6 and the driving element 3 may be a cable connection or a wireless connection.
[0073] For example, in some specific embodiments, the automatic control unit 71 includes an external signal receiving unit 713, which is electrically connected to the driver 3 to control the operation of the driver 3 based on an external signal received by the external signal receiving unit 713. In this case, the external signal receiving unit 713 can receive signals from an external smoke alarm, a temperature sensor installed in a cold storage, a city fire alarm, etc., without limitation.
[0074] In some specific examples, the door body 2 is slightly larger than the smoke exhaust port 200 , and the door body 2 is made of fire-resistant and heat-insulating material.
[0075] It should be further emphasized that the present application can isolate the cold bridge and reduce the loss of cooling capacity. It is estimated that the smoke exhaust outlet 200 area of 18.6 square meters will consume an additional 203 kWh of electricity per day to dissipate the cooling capacity. The cold storage operates for three quarters a year, saving about 300,000 yuan in electricity bills, which can reduce the cost of cold storage operation. In the event of a fire, the controller 7 will be linked with the fire protection system to open the door 2 in time, thereby improving fire safety. There is no need to change the smoke exhaust outlet 200.
[0076] The other configurations and operations of the smoke exhaust device 100 according to the embodiments of the present utility model are known to those of ordinary skill in the art and will not be described in detail here.
