Description

Technical Field

[0001] This utility model belongs to the technical field of fire-fighting equipment, specifically relating to a carbon dioxide gas fire box. Background Technology

[0002] Portable carbon dioxide fire extinguishers are common firefighting equipment widely used in various fire-fighting locations. A typical portable carbon dioxide fire extinguisher weighs approximately 7-15 kg. Due to the volatility of carbon dioxide, to determine if a portable carbon dioxide fire extinguisher has become ineffective due to prolonged storage or excessive evaporation, it is usually necessary to periodically test the extinguishers in the fire extinguisher box to assess their effectiveness. Currently, the common standard for judgment is to weigh the fire extinguisher and determine if the weight has decreased, or if the decrease is within the standard range. A weight of ±5% or ±50g of the fill weight is considered normal (not ineffective). However, in current technology, manual weighing requires operators to weigh each carbon dioxide fire extinguisher individually, which is physically demanding and time-consuming. Furthermore, manual testing is susceptible to weight deviations due to equipment and operational errors. Additionally, the requirement for periodic manual testing according to standards carries the risk of forgetting or making false weighings, leading to significant fire hazards caused by ineffective fire extinguishers.

[0003] In the prior art, such as the utility model patent CN113034860A entitled "An Intelligent Security System and Early Warning Method for Building Fire Protection Devices," the disclosed intelligent security system includes: a first placement plate, a second placement plate, a first weighing module, a second weighing module, and a monitoring center; both the first and second placement plates are installed inside a fire extinguisher box, the first weighing module is installed below the first placement plate, and the second weighing module is installed below the second placement plate; a carbon dioxide fire extinguisher is placed on the first placement plate, and a dry powder fire extinguisher is placed on the second placement plate; the first weighing module is used to detect the weight of the carbon dioxide fire extinguisher placed on the first placement plate, and the second weighing module is used to detect the weight of the dry powder fire extinguisher placed on the second placement plate; it also includes a radio communication module and a monitoring center; the radio communication module is installed inside the fire extinguisher box, and the radio communication module has a unique location information identifier; the radio communication module is wired to both the first and second weighing modules; the monitoring center is located in the building's monitoring room, and the monitoring center is wirelessly connected to the radio communication module; the unique location information identifier of the radio communication module is sent to the monitoring center in real time. The technical effect is as follows: the first and second weighing modules in each fire extinguisher box send the actual weight of the carbon dioxide fire extinguisher and dry powder fire extinguisher to the monitoring center in real time. The monitoring center judges the weight of the carbon dioxide fire extinguisher and the dry powder fire extinguisher. If the weight of the carbon dioxide fire extinguisher or the dry powder fire extinguisher is not within the set value, the monitoring center sends a carbon dioxide fire extinguisher leakage warning or a dry powder fire extinguisher overload warning, as well as the specific location information of the corresponding fire extinguisher box in the building, to the on-duty personnel's mobile phones via SMS. The on-duty personnel can promptly deal with and replace the faulty fire extinguisher located in the specific location in the building based on the unique location information sent by the radio communication module of each fire extinguisher box. This prevents the fire extinguisher from causing serious impact on people's lives and property safety due to the inability to replace it in time. At the same time, this targeted handling of fire extinguisher leakage and moisture failure greatly improves work efficiency and saves manpower and material resources.

[0004] This structure has the following main shortcomings: 1. The first weighing module used to detect the weight of the carbon dioxide fire extinguisher placed on the first placement plate and the second weighing module used to detect the weight of the dry powder fire extinguisher placed on the second placement plate are always subjected to the gravity of their respective carbon dioxide fire extinguishers. The springs used for measurement are always in a compressed state, which leads to metal fatigue. Over time, this can easily lead to a decrease in measurement accuracy and a large weight error. If the time is even longer, it is easy to fail. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a carbon dioxide gas fire box, which solves the problems of metal fatigue, failure, reduced accuracy and large error caused by the spring being in a compressed state in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A carbon dioxide gas fire extinguisher box includes a fire extinguisher box body, an interior cavity formed inside the fire extinguisher box body, a sealing plate on the fire extinguisher box body, and one or more fire extinguisher support frames at the bottom of the cavity, with one carbon dioxide gas fire extinguisher placed on each fire extinguisher support frame; characterized in that: a weighing module is provided at the bottom of the cavity for measuring the mass of the carbon dioxide gas fire extinguisher.

[0008] It is also equipped with a power unit, which is connected to the weighing module or the support frame. The power unit drives the weighing module and the carbon dioxide fire extinguisher on the support frame to move closer or further apart. When the weighing module and the carbon dioxide fire extinguisher approach and make contact, the mass of the carbon dioxide fire extinguisher can be measured. When the weighing module and the carbon dioxide fire extinguisher move away from each other, they lose contact.

[0009] This utility model relates to a fire extinguisher box. The fire extinguisher inside the box is supported on a bottom support frame. When not measuring, the weighing module (sensor) is not in contact with the fire extinguisher. When measurement is required, the fire extinguisher and the weighing module (sensor) move closer together and into contact, allowing the weighing module (sensor) to detect the weight of the fire extinguisher. After measurement, the fire extinguisher and the weighing module (sensor) move away from each other and disengage. This effectively prevents the weighing module (sensor) from being pressed down by the fire extinguisher for extended periods, preventing metal fatigue of the support spring and preventing spring failure under the long-term pressure of the fire extinguisher.

[0010] Furthermore: the support frame includes a tray and vertical support rods. The upper tray is used to place the carbon dioxide fire extinguisher. There are multiple vertical support rods, which are arranged vertically and connected to the tray at their upper ends. The weighing module is located under the tray. When the power device drives the weighing module to move upward, the tray and the carbon dioxide fire extinguisher are supported by the weighing module, and the weighing module can measure the mass of the tray and the carbon dioxide fire extinguisher.

[0011] Furthermore, the vertical support rods are three or four arranged circumferentially.

[0012] Furthermore: perforations are made on the tray, and the upper end of each vertical support rod is inserted into a perforation.

[0013] Furthermore, a lifting connector is installed between the power unit and the weighing module, or between the power unit and the support frame. One end of the lifting connector is connected to the output shaft of the power unit, and the other end is connected to the support frame or the weighing module, so that the rotation of the output shaft of the power unit is converted into the vertical lifting motion of the support frame or the weighing module.

[0014] Furthermore, a data processor is also installed on the fire box body. The data processor is electrically connected to the weighing module, receives the measurement data from the weighing module, performs calculations through its internal program, and sends the relevant signals to the signal processing unit or control center through its internal signal transmission module.

[0015] Furthermore, an operating keyboard is also installed on the surface of the fire extinguisher box, and the operating keyboard is electrically connected to the data processor.

[0016] Furthermore: The display device is electrically connected to the data processor, and relevant signals are input into the display device to display the weight of the carbon dioxide fire extinguisher in real time.

[0017] Compared with existing technologies, the carbon dioxide gas fire extinguishing box of this invention has the following advantages:

[0018] 1. The carbon dioxide gas fire extinguisher box of this utility model has a fire extinguisher supported on a support frame at the bottom. When not measuring, the weighing module (sensor) is not in contact with the fire extinguisher. When measurement is required, the fire extinguisher and the weighing module (sensor) move closer together and come into contact. The weighing module (sensor) senses the weight of the fire extinguisher and completes the weight detection. After the measurement is completed, the fire extinguisher and the weighing module (sensor) move away from each other and disengage. This effectively avoids the weighing module (sensor) being pressed down by the fire extinguisher for a long time, prevents metal fatigue of the support spring, and prevents the support spring from failing under the long-term pressure of the fire extinguisher.

[0019] 2. The carbon dioxide gas fire extinguisher box of this utility model does not have contact between the weighing module (sensor) and the fire extinguisher during non-measuring periods. This provides measurement accuracy while preventing the failure of the support spring due to fatigue, thus extending the overall service life.

[0020] 3. The carbon dioxide gas fire box described in this utility model can significantly reduce measurement errors and effectively improve measurement accuracy.

[0021] 4. Combined with numerical display and measurement data transmission, this utility model provides precise, controllable, and intelligent "technical" and "physical" information-based measures for fire safety in computer rooms; effectively meeting the monitoring needs of fire protection devices, avoiding failure of fire protection devices due to human error or equipment malfunction; and strengthening the real-time monitoring of the status of fire protection devices in the standardized construction of information computer rooms, especially for unattended Class C computer rooms.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Example

[0027] Please see Figure 1 As shown in Figure 3, this utility model discloses a carbon dioxide gas fire extinguisher box, comprising a fire extinguisher box body 1, with an internal cavity 2 for accommodating a carbon dioxide gas fire extinguisher. A sealing plate 3 is also provided on the fire extinguisher box body 1, acting as a lid, which can be flipped open or closed to enclose the portable carbon dioxide gas fire extinguisher within the fire extinguisher box body 1. At the bottom of the cavity 2, one or more fire extinguisher support frames 10 are provided. A typical configuration involves placing two carbon dioxide gas fire extinguishers inside the fire extinguisher box body 1, as shown in the figure, with two fire extinguisher support frames 10 on the left and right sides. In use, each fire extinguisher support frame 10 corresponds to one carbon dioxide gas fire extinguisher. The above is prior art and will not be further described here.

[0028] The improvement of this utility model is that a weighing module 11, also called a sensor, is set at the bottom of the cavity 2 to measure the mass (weight) of the carbon dioxide fire extinguisher. A power device 12, usually an electric motor, is also provided. The power device 12 is connected to the weighing module 11 or to the support frame 10, driving the weighing module 11 and the support frame 10 (on which the carbon dioxide fire extinguisher is located) to move closer or further apart. When the weighing module 11 approaches and contacts the carbon dioxide fire extinguisher on the support frame 10, it can sense and measure the mass (weight) of the carbon dioxide fire extinguisher. When the weighing module 11 moves away from the carbon dioxide fire extinguisher on the support frame 10, the two lose contact, and the weighing module 11 can no longer measure the mass (weight) of the carbon dioxide fire extinguisher.

[0029] This utility model uses the rotation of the power device 12 to drive the weighing module 11 or the support frame 10 to move up or down, so that the weighing module 11 and the carbon dioxide gas fire extinguisher move closer or further apart. There are two main types of specific structures.

[0030] In the first structure shown in the figure, the power unit 12 is connected to the weighing module 11 and can drive the weighing module 11 to move up and down. The support frame 10 includes a tray 13 and vertical support rods 14. The support frame 10 has no power and cannot move up and down because it is not connected to the power unit 12. The upper tray 13 is used to place the carbon dioxide fire extinguisher and bear its weight. There are multiple vertical support rods 14, arranged vertically, usually three or four evenly arranged around the circumference. The upper end of the vertical support rods 14 is connected to the tray 13 and supports the weight of the tray 13 and the carbon dioxide fire extinguisher on the tray 13. The weighing module 11 is set below the tray 13 and is at a distance required by the process from the lower surface of the tray 13. When the power unit 12 drives the weighing module 11 upward, the weighing module 11 first contacts the lower surface of the tray 13. During the upward movement, it moves the tray 13 and the carbon dioxide fire extinguisher upward, causing the tray 13 to disengage from the vertical support rod 14. The tray 13 and the carbon dioxide fire extinguisher are supported by the weighing module 11, which then measures the mass of the tray 13 and the carbon dioxide fire extinguisher. Subtracting the mass of the tray 13 from this measurement gives the mass of the carbon dioxide fire extinguisher. After each measurement, the power unit 12 drives the weighing module 11 downward, causing the tray 13 and the carbon dioxide fire extinguisher to move downward until they are supported on the vertical support rod 14. The weighing module 11 then no longer contacts the tray 13 and does not bear the weight of the carbon dioxide fire extinguisher.

[0031] In the second structure of this utility model, the power unit 12 is connected to the support frame 10, driving the support frame 10 to move up and down. If connected to the tray 13 or vertical support rod 14 of the support frame 10, the weighing module 11 is positioned below the tray 13, at a required distance from the lower surface of the tray 13. When the power unit 12 drives the support frame 10 downwards, the tray 13 of the support frame 10 contacts the weighing module 11 as it descends. During the descent, the tray 13 and the carbon dioxide fire extinguisher are supported by the weighing module 11, allowing the weighing module 11 to measure the mass of the tray 13 and the carbon dioxide fire extinguisher. Subtracting the mass of the tray 13 from this measurement yields the mass of the carbon dioxide fire extinguisher. After each measurement, the power unit 12 drives the support frame 10 upwards, moving the tray 13 and the carbon dioxide fire extinguisher upwards until they are supported on the vertical support rod 14. The weighing module 11 then does not contact the tray 13 and does not bear the weight of the carbon dioxide fire extinguisher.

[0032] The two structures of this utility model, after the measurement is completed, disconnect the fire extinguisher from the weighing module (sensor). This can effectively prevent the weighing module (sensor) from being pressed down by the fire extinguisher for a long time, prevent the supporting spring of the weighing module from experiencing metal fatigue, and prevent the supporting spring from failing under the long-term pressure of the fire extinguisher.

[0033] To prevent the tray 13 from rotating circumferentially, and thus to prevent the carbon dioxide fire extinguisher on the tray 13 from rotating, corresponding perforations 15 are provided on the tray 13. The upper end of each vertical support rod 14 is inserted into a perforation 15 to prevent the tray 13 and the carbon dioxide fire extinguisher from rotating circumferentially, thus keeping their positions relatively fixed. The vertical support rods 14 can be existing flanged support columns.

[0034] A lifting connector 16 can be added between the power unit 12 and the weighing module 11, or between the power unit 12 and the support frame 10. One end of the lifting connector 16 is connected to the output shaft of the power unit 12, and the other end is connected to the support frame 10 or the weighing module 11, so as to convert the rotation of the output shaft of the power unit 12 into the vertical lifting motion of the support frame 10 or the weighing module 11.

[0035] To enhance the intelligence of this carbon dioxide fire extinguisher box, a data processor is installed on the box body 1. The data processor is electrically connected to the weighing module 11, receiving measurement data from the weighing module 11 via wired or wireless connection. After calculation by its internal program, the data processor sends relevant signals (the original measurement data from the weighing module 11 or the calculated data) to the signal processing unit or control center via its internal signal transmission module. This allows the control center to monitor the weight of each carbon dioxide fire extinguisher and determine whether the extinguisher has failed by checking if the weight change exceeds the required range. The data processor can be housed inside the fire extinguisher box body 1, which provides protection for it. A display device can also be installed, electrically connected to the data processor, to input relevant signals and display the real-time weight of the carbon dioxide fire extinguishers.

[0036] An operation keyboard 17 is also provided on the surface of the fire box body 1. The operation keyboard 17 is electrically connected to the data processor. With the support of the relevant processing program in the data processor, the carbon dioxide gas fire box of this utility model can be controlled to produce corresponding actions through the control buttons of the operation keyboard 16, thereby improving the level of automation and intelligence.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
