Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to a fire-fighting fan mechatronic monitoring device and method. Background Art

[0002] As an important fire safety equipment, the fire fan plays a key role in exhausting smoke and supplying air during a fire. When there is no fire, the fire fan is also used to ventilate the interior of the building. Fire fans are generally equipped with a monitoring system to monitor the operating status of the fire fan and the internal conditions of the building. The general monitoring system includes an analysis monitoring center and multiple detection devices. Multiple detection devices are used to detect different parameters of the fan, such as smoke detection devices, temperature detection devices, and wind speed detection devices. The wind speed detection device is set inside the pipe connected to the fire fan.

[0003] The wind speed detection device generally includes a speed sensor and a shaft, and the rotating rod is rotatably mounted on the speed sensor. Multiple blades are fixedly mounted on the rotating rod. After the fire fan is started, the wind flows along the pipe and pushes the blades, thereby rotating the rotating rod. The speed sensor generates a speed signal according to the rotation speed of the rotating rod and sends it to the analysis and monitoring center, which analyzes the speed signal to obtain the wind speed.

[0004] However, the fire fan will be started for ventilation when there is no fire, so that the rotating rod is rotated all the time. When the rotating rod rotates for a long time, the connection between the rotating rod and the speed sensor is easy to wear, so that the detection device is easy to be damaged. Summary of the invention

[0005] In order to reduce the occurrence of damage to the detection device, the present application provides a fire-fighting fan mechatronic monitoring device and method.

[0006] The present application provides a fire-fighting fan mechatronic monitoring device and method, which adopts the following technical solutions: A mechatronic monitoring device for a fire-fighting fan, wherein the detection device is installed on a pipe connected to the fire-fighting fan, and comprises a mounting seat and a mounting cover, wherein the mounting seat is installed inside the pipe, and the mounting cover is installed outside the pipe, the mounting seat is hinged with a pressure plate, and the mounting cover is used to be fixedly connected to the outer wall of the pipe, a pressure sensor is fixedly installed inside the mounting cover, a pressure rod is arranged inside the mounting cover, the pipe is provided with a through hole for the pressure rod to pass through, a first elastic block is fixedly installed on one end of the pressure rod close to the pressure sensor, the first elastic block abuts against the pressure sensor, and the end of the pressure rod away from the pressure sensor abuts against the pressure plate.

[0007] By adopting the above technical solution, after the fire-fighting fan is started, the wind flows inside the pipe, and the wind squeezes the pressure plate to rotate toward the pressure sensor, so that the pressure plate applies pressure to the pressure rod, thereby increasing the pressure of the pressure rod on the first elastic block. The pressure of the first elastic block on the pressure rod increases, thereby increasing the pressure of the first elastic block on the pressure sensor. The pressure sensor generates a pressure signal according to the pressure of the first elastic block, and then the pressure sensor sends the pressure signal to the analysis and monitoring center. The analysis and monitoring center obtains the wind speed according to the pressure signal.

[0008] When the fire fan is just started, the pressure plate is pushed by the wind and rotates greatly. After the fire fan is stable, the pressure plate is pushed by the wind and rotates less, thereby reducing the possibility of damage to the connection between the pressure plate and the mounting seat, thereby reducing the possibility of damage to the detection device.

[0009] Optionally, the mounting seat and the mounting cover are both located on the side wall of the pipe, the side wall of the mounting seat is provided with a rotation groove for one side of the pressure plate to pass through, a shaft rod is rotatably inserted inside the rotation groove, and the pressure plate is fixedly connected to the shaft of the shaft rod.

[0010] By adopting the above technical solution, the mounting seat and the mounting cover are both located on the inner wall of the pipe, and dust can easily fall off the pressure plate, which is conducive to keeping the pressure plate clean. Before the fire-fighting fan is started, the wind force inside the pipe is small, and the pressure plate may rotate away from the pressure rod. Entering the rotating groove through one side of the pressure plate, the inner wall of the rotating groove limits the rotation angle of the pressure plate, thereby reducing the distance between the pressure plate and the pressure rod after the fire-fighting fan is turned off. After the fire-fighting fan is started, the pressure plate rotates toward the pressure rod and squeezes. Since the distance between the pressure plate and the pressure rod is small, the pressure plate is less likely to be damaged after hitting the pressure rod.

[0011] Optionally, a shielding sheet is fixedly mounted on the mounting seat along the notch of the rotating groove, the shielding sheet is flexible, and the pressing plate is fixedly passed through the shielding sheet.

[0012] By adopting the above technical solution, the shielding sheet is used to block dust from entering the interior of the rotating groove, thereby reducing the situation in which the rotation resistance is increased after the dust contaminates the shaft.

[0013] Optionally, a connecting plate is fixedly installed on one side of the mounting seat close to the pressure plate, and the connecting plate is provided with a mounting tube. The mounting tube is fixedly passed through the connecting plate, and the connecting plate is abutted against the inner wall of the pipe. The through hole is rectangular, and the cross-sections of the mounting tube and the pressure rod are both rectangular. The mounting tube damping is passed through the through hole, and the pressure rod is slidably passed through the mounting tube.

[0014] By adopting the above technical solution, the installation tube is inserted into the through hole, so that the installation seat is installed inside the pipeline, thereby reducing the damage to the pipeline when the detection device is installed.

[0015] Optionally, the mounting cover is provided with a screw, and the screw is matched with a nut, the side wall of the mounting cover is provided with a first mounting hole for the screw to pass through, the mounting tube passes through the through hole and is partially located inside the mounting cover, a receiving port is provided on the peripheral side of the mounting tube, a rotating rod is rotatably inserted inside the receiving port, a mounting block is fixedly installed on the rod body of the rotating rod, and the mounting block is provided with a second mounting hole for the screw to pass through.

[0016] By adopting the above technical solution, the mounting block is allowed to enter the interior of the mounting tube from the receiving port, and then the mounting tube is allowed to pass through the through hole, thereby reducing the possibility that the mounting block will hinder the mounting tube from passing through the through hole. Then, the pressure rod is allowed to pass through the mounting block, and the pressure rod pushes the mounting block to rotate, and the mounting block slides out of the mounting tube from the receiving port. Then, the mounting cover is pressed against the outer wall of the pipe, and the first mounting hole and the second mounting hole are aligned. After the screw rod passes through the first mounting hole and the second mounting hole, it is tightened with a nut, thereby facilitating the installation of the mounting cover on the outer wall of the pipe, while reducing the damage to the pipe after the mounting cover is installed on the pipe.

[0017] Optionally, a telescopic hole is provided on the side wall of the mounting block, the telescopic hole is connected to the second mounting hole, a slider is slidably provided inside the telescopic hole, a second elastic block is fixedly installed on the side of the slider facing the outside of the second mounting hole, and the second elastic block is used to tightly press against the outer wall of the pipe.

[0018] By adopting the above technical solution, after the screw rod passes through the second mounting hole, the slider slides out of the telescopic hole, and the second elastic block is pressed against the outer wall of the pipe, so that the connecting plate inside the pipe is also pressed against the inner wall of the pipe, thereby forming a clamping effect. The connecting plate and the second elastic block clamp the pipe wall, thereby improving the firmness of the detection device installed on the pipe.

[0019] Optionally, the side of the sliding block away from the elastic block is tilted to allow the screw rod to push the sliding block.

[0020] By adopting the above technical solution, after the screw rod passes through the second mounting hole, the screw rod squeezes the inclined side of the slider, so that the slider extends out of the telescopic hole, thereby facilitating the second elastic block to be tightly pressed against the outer wall of the pipe.

[0021] Optionally, a shielding cover is fixedly installed between the rod body of the pressure rod and the connecting plate, and the shielding cover is flexible.

[0022] By adopting the above technical solution, the shielding cover prevents dust from entering the gap between the pressure rod and the mounting tube, thereby facilitating the sliding of the pressure rod inside the mounting tube.

[0023] Optionally, the mounting seat is tilted away from a side of the pressure plate.

[0024] By adopting the above technical solution, the wind flows along the pipeline and squeezes the inclined side of the mounting seat, and is guided by the inclined side of the mounting seat. The wind presses the mounting seat against the inner wall of the pipeline, thereby reducing the situation where the wind drives the mounting seat away from the inner wall of the pipeline.

[0025] A fire-fighting fan mechatronic monitoring method comprises the following steps: After the fire-fighting fan is started, the wind flows along the pipe, and the pressure plate is squeezed by the wind and rotates toward the pressure rod; The pressure rod is squeezed by the pressure plate to drive the first elastic block to press the pressure sensor; The pressure sensor generates a pressure signal according to the pressure exerted on the first elastic block and sends the pressure signal to the analysis and monitoring center.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the fire fan is started, the wind drives the pressure plate to rotate and squeeze the pressure rod. When the fire fan is just started, the pressure plate rotates with a large amplitude. After the fire fan runs stably, the pressure plate rotates due to the change in wind force, and the rotation amplitude is small, thereby reducing the possibility of damage to the connection between the pressure plate and the mounting seat, thereby reducing the possibility of damage to the detection device; 2. The through hole allows the installation pipe to pass through, so that the installation base can be installed on the inner wall of the pipe. The installation cover is installed on the installation pipe through bolts and nuts, so that the installation cover can be installed on the outer wall of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-8 This application is described in further detail.

[0030] The embodiments of the present application disclose a mechatronic monitoring device and method for a fire-fighting fan.

[0031] Reference Figure 1 , Figure 2 , Figure 3 A fire-fighting fan mechatronic monitoring device is installed on a pipe 1 connected to the fire-fighting fan, and includes a mounting seat 2, a connecting plate 3 is fixedly installed on one side of the mounting seat 2, and the connecting plate 3 is provided with a mounting pipe 4, and the mounting pipe 4 is fixedly passed through the connecting plate 3. A through hole 5 is opened on the inner side wall of the pipe 1 for the mounting pipe 4 to pass through. The cross section of the mounting pipe 4 is rectangular, and the through hole 5 is also rectangular.

[0032] The mounting tube 4 is inserted into the through hole 5. Since the through hole 5 and the mounting tube 4 are both rectangular, the mounting tube 4 is restricted from rotating inside the through hole 5. At the same time, after the mounting tube 4 is inserted into the through hole 5, the mounting seat 2 is also installed on the inner wall of the pipe 1. When the mounting seat 2 is installed on the inner wall of the pipe 1, the connecting plate 3 is abutted against the inner wall of the pipe 1.

[0033] Reference Figure 3 , Figure 4 The mounting seat 2 is tilted away from the wind direction in the pipe 1. When the wind flows in the pipe 1, it is guided by the tilted side of the mounting seat 2, so that the wind drives the mounting seat 2 to press against the inner wall of the pipe 1, thereby improving the firmness of the mounting seat 2 installed in the pipe 1.

[0034] The mounting seat 2 is provided with a rotation slot 6 on one side facing the wind flow direction. A shaft rod 7 is rotatably inserted inside the rotation slot 6, and a pressing plate 8 is fixedly installed on the shaft rod 7, and a part of the pressing plate 8 is located inside the rotation slot 6.

[0035] After the fire fan is started, wind flows inside the pipe 1, and the wind pushes the pressing plate 8 to rotate toward the inner wall of the pipe 1. At the same time, dust in the environment will also enter the pipe 1, and the dust will stick to the pressing plate 8. Through the mounting seat 2 and the pressing plate 8 on the inner wall of the pipe 1, it is convenient for the dust to fall from the pressing plate 8, thereby improving the cleanliness of the pressing plate 8.

[0036] Reference Figure 3 , Figure 4 The mounting seat 2 is fixedly mounted with a shielding piece 9 along the notch of the rotating groove 6, the shielding piece 9 is flexible, and the pressing plate 8 is fixedly penetrated through the shielding piece 9. The shielding piece 9 blocks dust from entering the rotating groove 6, thereby reducing the situation where dust increases the rotation resistance of the shaft 7.

[0037] Reference Figure 5 , Figure 6 , Figure 7 , the portion of the installation tube 4 that passes through the through hole 5 is located outside the pipeline 1. The portion of the installation tube 4 that is located outside the pipeline 1 is provided with a receiving opening 10. A rotating rod 11 is rotatably inserted inside the receiving opening 10. A mounting block 12 is fixedly mounted on the rotating rod 11. Before the installation tube 4 is inserted into the through hole 5, the rotating mounting block 12 is rotated to enter the interior of the installation tube 4 from the receiving opening 10, thereby facilitating the insertion of the installation tube 4 into the through hole 5.

[0038] Reference Figure 6 , Figure 7 , Figure 8 The outer wall of the pipe 1 is provided with a mounting cover 13, the mounting cover 13 is provided with a screw 14, and the screw 14 is matched with a nut 15. The mounting cover 13 is provided with a first mounting hole 16 for the screw 14 to pass through, and the mounting block 12 is provided with a second mounting hole 17 for the screw 14 to pass through.

[0039] After the mounting tube 4 passes through the through hole 5, the mounting block 12 is rotated and removed from the inside of the mounting tube 4. Then, the first mounting hole 16 and the second mounting hole 17 are aligned, the screw rod 14 is passed through the first mounting hole 16 and the second mounting hole 17, and then the nut 15 is tightened, so that the mounting cover 13 is conveniently mounted on the outer wall of the pipeline 1.

[0040] The side wall of the mounting block 12 is provided with a telescopic hole 18, which is connected to the second mounting hole 17. A slider 19 is slidably arranged inside the telescopic hole 18, and a second elastic block 21 is fixedly mounted on the side of the slider 19 facing the outside of the second mounting hole 17. The slider 19 is tilted away from the elastic block. After the screw rod 14 passes through the second mounting hole 17, the screw rod 14 and the inclined side of the slider 19 are pressed against each other, so that the slider 19 drives the second elastic block 21 to press against the outer wall of the pipe 1. The second elastic block 21 presses against the outer wall of the pipe 1, and the connecting plate 3 also presses against the inner wall of the pipe 1, so that the second elastic block 21 and the connecting plate 3 clamp the pipe wall of the pipe 1, thereby improving the firmness of the detection device installed on the pipe 1.

[0041] Reference Figure 3A pressure sensor 22 is fixedly installed inside the mounting cover 13, a pressure rod 23 and a first elastic block 20 are arranged inside the mounting cover 13, one side of the first elastic block 20 is pressed against the pressure sensor 22, and the other side of the first elastic block 20 is fixedly connected to one end of the pressure rod 23. One end of the pressure rod 23 away from the first elastic block 20 is passed through the mounting block 12 and then pressed against the pressure plate 8.

[0042] After the pressure plate 8 is pushed by the wind, the pressure rod 23 rotates, and the pressure applied by the pressure rod 23 to the pressure sensor 22 through the first elastic block 20 increases. The pressure sensor 22 generates a pressure signal according to the pressure of the first elastic block 20. Then the pressure sensor 22 sends the pressure signal to the analysis and monitoring center, which analyzes the pressure signal to obtain the wind speed.

[0043] At the same time, when the pressing rod 23 is inserted into the mounting tube 4 , the pressing rod 23 will push the mounting block 12 to rotate, thereby facilitating the mounting block 12 to rotate from the receiving opening 10 to the outside of the mounting tube 4 .

[0044] Reference Figure 3 , Figure 4 A shielding cover 24 is fixedly installed between the rod body of the pressure rod 23 and the connecting plate 3. The shielding cover 24 is flexible. The shielding cover 24 is used to shield dust from entering the gap between the pressure rod 23 and the mounting tube 4, thereby reducing the situation in which the resistance of the pressure rod 23 sliding inside the mounting tube 4 increases after the dust enters the gap between the pressure rod 23 and the mounting tube 4.

[0045] A fire-fighting fan mechatronic monitoring method, applied to a fire-fighting fan mechatronic monitoring device of the present application, comprises the following steps: After the fire-fighting fan is started, the wind flows along the pipe 1, and the pressure plate 8 is squeezed by the wind force and rotates toward the pressure rod 23; The pressure rod 23 is squeezed by the pressure plate 8 to drive the first elastic block 20 to press the pressure sensor 22; The pressure sensor 22 generates a pressure signal according to the pressure exerted on the first elastic block 20 and sends the pressure signal to the analysis and monitoring center.

[0046] The implementation principle of the electromechanical integrated monitoring device and method for fire-fighting fans in the embodiment of the present application is as follows: insert the mounting tube 4 from the through hole 5, thereby installing the mounting seat 2 inside the pipe 1. Then, after the pressure rod 23 passes through the mounting tube 4, the mounting cover 13 is connected to the portion of the mounting tube 4 located outside the pipe 1 through the screw 14 and the nut 15, thereby installing the mounting cover 13 on the outer wall of the pipe 1. The entire detection device is installed through one through hole 5, and the installation of the detection device causes little damage to the pipe 1.

[0047] After the fire-fighting fan is started, the wind flows along the pipeline 1 and pushes the pressure plate 8 to rotate toward the pressure rod 23, thereby increasing the pressure on the pressure rod 23 from the pressure plate 8. As the pressure on the pressure rod 23 increases, the pressure applied by the pressure rod 23 to the pressure sensor 22 through the first elastic block 20 also increases. The pressure sensor 22 generates a pressure signal based on the pressure received and sends it to the analysis and monitoring center, which analyzes the pressure signal to obtain the wind speed, thereby facilitating the wind speed at the location of the detection device after the fire-fighting fan is started. When the wind speed at the location of the detection device is low, the analysis and monitoring center promptly issues an alarm to remind.

[0048] When the fire fan is just started, the pressure plate 8 rotates under the push of the wind and squeezes the pressure rod 23. After the fire fan is running stably, the wind speed inside the pipeline 1 changes little, and the pressure plate 8 also rotates slightly, thereby reducing the wear and damage of the connection between the shaft rod 7 and the mounting seat 2 after the pressure rod 23 drives the shaft rod 7 to rotate, thereby reducing the damage of the detection device.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
