Description

Technical Field

[0001] The present invention relates to the technical field of fire protection, and in particular to an on-duty robot for an intelligent fire control room. Background Art

[0002] The fire control room duty robot system consists of a fire control room duty robot terminal box, a fire control room duty robot body, a network camera, an infrared aimer, etc. The fire control room duty robot terminal box is connected to the fire control room duty robot body to perform various command control, programming and other operations, and communicate with the host computer platform.

[0003] However, existing fire control room duty robots mostly use mechanical pressing to trigger terminal buttons. Due to the lack of a buffer mechanism, the button structure is easily damaged (such as keycap breakage and internal contact deformation) due to excessive pressing force or uncontrolled stroke.

[0004] In view of this, research and improvement are carried out to the existing problems, and an intelligent fire control room duty robot is provided, aiming to solve the problem and improve the practical value through this technology. Summary of the Invention

At the same time, the air gap is expanded to make the magnetic coupling invalid, preventing excessive pressing from damaging the button and improving the service life.

[0016] Preferably, the air outlet of the jet ring is arranged in a ring shape and is arranged parallel to the surface of the camera, and a filter plate is installed at the opening of the cylinder.

[0017] Preferably, the outer wall of the fixing plate is covered with a protective shell, the outer wall of the protective shell is covered with a flow guide cover, and the outer wall of the protective shell is provided with multiple groups of exhaust ports.

[0018] Preferably: the protective mechanism includes a liquid storage box arranged on the outside of the camera, an elastic diaphragm is provided on one side of the liquid storage box, and multiple groups of nozzles are installed on the other side of the liquid storage box. A connecting rod is installed on the side wall of the pressing plate, and an extrusion plate is installed at one end of the connecting rod, and the extrusion plate is movably connected to the elastic diaphragm.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention uses a drive motor to rotate the transmission rod. Because the active magnet is slidably connected to the transmission rod, it rotates synchronously with it. The active magnet and the driven magnet are magnetically coupled, driving the driven magnet and the screw to rotate, causing the nut seat to move axially along the screw, driving the camera and the press plate to move laterally. When the press plate contacts the key, the piston rod slides into the sleeve to compress spring A. Spring A reduces the impact force through elastic deformation, ensuring a gentle and stable pressing action. When the piston rod compresses spring A to a set threshold, the elastic force of spring A matches the key triggering force, and the press plate accurately presses the key to complete the command. At the same time, the movement of the piston rod drives push rod A to compress gas in sleeve A. The gas enters sleeve B through the connecting pipe and pushes push rod B, driving the active magnet away from the driven magnet and expanding the air gap. When the air gap exceeds the threshold, the magnetic coupling fails. Even if the drive motor continues to rotate, power cannot be transmitted to the screw, and the screw stops rotating. This prevents the nut seat from continuing to move, causing excessive key pressing, extrusion deformation, and damage to the circuit board. This improves the service life of the key, reduces equipment maintenance costs, and ensures the stability of the fire control system and the efficiency of fire emergency response.

[0021] 2. The present invention uses a driving motor to start and rotate the transmission rod, and the fan blades on the rotating rod rotate at high speed through the transmission mechanism, forming a negative pressure in the cylinder to inhale external air. After the air is purified by the filter plate, it is transported to the jet ring on the outer wall of the camera by the air supply pipe A. The air outlets of the jet ring are arranged in parallel in a ring shape to eject high-speed airflow, forming an air curtain on the surface of the camera lens, which can block dust and water vapor, disperse attached particles, keep the lens clean, and avoid image blur. At the same time, the air curtain circulation can also take away the heat from the camera, assist in heat dissipation, and extend the service life. In addition, when the protective shell covers the button, the air curtain airflow is discharged through the exhaust port of the protective shell, and is blown to the key slot under the guidance of the deflector cover, removing dust and metal debris, improving the button trigger response speed and reliability, avoiding circuit failure caused by impurities, and ensuring that the fire control system command input is accurate and timely.

[0022] 3. The present invention applies pressure to the elastic diaphragm through the extrusion plate under the action of the pre-tightening force of spring A, so that the liquid storage box maintains a slight positive pressure. When the pressing mechanism performs a key operation, the pressing plate moves to release the pressure, and the connecting rod drives the extrusion plate away from the diaphragm. The diaphragm returns to its original state, and the pressure in the liquid storage box decreases. After the key operation is completed, the drive motor reverses, and the pressing plate moves in the opposite direction under the action of the rebound force of spring A. The extrusion plate is pushed by the connecting rod to squeeze the diaphragm again. As the deformation of the diaphragm intensifies, the pressure in the liquid storage box increases, forcing the rust inhibitor to be sprayed out in a fan shape through the nozzle, forming a protective film on the metal surface, isolating water vapor and corrosive gases, slowing down oxidation, ensuring operational stability, and reducing the risk of key failure.

DETAILED DESCRIPTION

[0032] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See Figures 1 to 7 As shown, the present invention provides an on-duty robot for an intelligent fire control room, comprising a linear motor A2 mounted on a terminal 1, a linear motor B3 mounted on the moving end of the linear motor A2, and a pressing mechanism 5 mounted on the moving end of the linear motor B3;

[0034] The pressing mechanism 5 includes a slide rail 501 installed at the mover end of the linear motor B3, a transmission rod 503 and a screw rod 504 rotate in the slide rail 501, a nut seat 505 is threadedly connected to the outer wall of the screw rod 504, a camera 506 is installed at one end of the nut seat 505, a fixing plate 507 is installed on the outer wall of the camera 506, a sleeve 508 is installed on one side of the fixing plate 507, a piston rod 509 slides inside the sleeve 508, a pressing plate 511 is installed at one end of the piston rod 509, an active magnet 512 slides on the outer wall of the transmission rod 503, a driven magnet 513 is installed on the side of the screw rod 504 close to the active magnet 512, and an adjustment mechanism 8 is installed between the pressing plate 511 and the active magnet 512;

[0035] It should be noted that when the terminal 1 receives a fire signal, the control system immediately triggers linear motors A2 and B3, driving the pressing mechanism 5 to rapidly move within the XY plane of the terminal 1 surface according to a preset program, allowing the camera 506 mounted on the nut seat 505 to accurately position itself directly above the target button 4. At this point, the camera 506 quickly activates its image acquisition function, capturing the area surrounding the button 4. Using a built-in image recognition algorithm, it analyzes the button 4's logo and color characteristics to confirm its function, effectively avoiding potential misjudgment by manual operation. Once the target button 4 is confirmed, the drive motor 502 activates, driving the transmission rod 503 to rotate. Because the active magnet 512 and the transmission rod 503 are slidably connected via a slot, the active magnet 512 rotates synchronously with the transmission rod 503. By utilizing the magnetic coupling between the active magnet 512 and the driven magnet 513, the driven magnet 513 will be driven to rotate, thereby driving the screw rod 504 to rotate synchronously. As the screw rod 504 rotates, the nut seat 505 that is threaded with the screw rod 504 will move axially along the screw rod 504, thereby driving the camera 506 and the pressing plate 511 to move laterally synchronously. When the pressing plate 511 contacts the target button 4, as the nut seat 505 continues to move, the piston rod 509 will slide into the inside of the sleeve 508, compressing the spring A510 and accumulating elastic potential energy. When the pressing plate 511 contacts the button 4, the spring A510 reduces the impact force through elastic deformation, avoiding damage to the button 4 due to rigid contact, and ensuring that the pressing action is soft and stable.

[0036] As the piston rod 509 further compresses the spring A510, since the button 4 is a mechanical key with a certain pressing resistance, it needs to overcome a certain resistance stroke to be triggered. Therefore, when the compression of the spring A510 reaches the set threshold, the elastic force generated by the spring A510 matches the force required to trigger the button 4. At this time, the pressing plate 511 will accurately press the target button 4 to complete the operation instruction; at the same time, in the process of the piston rod 509 moving into the sleeve 508, the pressing plate 511 drives the push rod A804 to move inside the sleeve A801, so that the push rod A804 compresses the gas inside the sleeve A801, so that the gas enters the sleeve B802 through the connecting pipe 803, so that the gas pushes the push rod B805 to move, further The push rod B805 drives the active magnet 512 to move toward the side away from the driven magnet 513, so that the air gap between the active magnet 512 and the driven magnet 513 gradually expands; when the air gap exceeds a certain threshold, the magnetic coupling effect fails. At this time, although the drive motor 502 continues to rotate, the power cannot be transmitted to the screw rod 504, and the screw rod 504 stops rotating, thereby preventing the button 4 from being over-pressed, squeezed and deformed due to the continuous movement of the nut seat 505, and even damaging the circuit board under the button 4, thereby increasing the service life of the button 4 of the terminal 1, reducing the equipment maintenance and replacement costs, ensuring the stability of the fire control system in frequent use scenarios, avoiding the inability to input commands normally due to damage to the button 4, and improving the efficiency of fire emergency response.

[0037] An air curtain mechanism 6 is provided on the outer wall of the camera 506. The air curtain mechanism 6 includes a mounting frame 601 mounted on one side of the slide rail 501. A cylinder 602 is mounted on one side of the mounting frame 601. A rotating rod 603 rotates inside the cylinder 602. A fan blade 604 is mounted on the outer wall of the rotating rod 603. A transmission mechanism is provided between the transmission rod 503 and the rotating rod 603. An air jet ring 608 is mounted on the outer wall of the camera 506. An air supply pipe A609 is connected between the cylinder 602 and the air jet ring 608.

[0038] It should be noted that when the driving motor 502 is started and drives the transmission rod 503 to rotate, the transmission rod 503 drives the rotating rod 603 to rotate through the transmission mechanism, and the fan blades 604 on the rotating rod 603 rotate at high speed, forming a negative pressure in the cylinder 602, sucking in the external air, and the sucked air is purified by the filter plate at the opening of the cylinder 602 to remove impurities such as dust and particulate matter, and then transported to the jet ring 608 on the outer wall of the camera 506 through the air pipe A609. Since the air outlet of the jet ring 608 is arranged in a ring shape and is parallel to the surface of the camera 506, the high-speed airflow from the jet ring 608 is discharged. After the air is ejected from the outlet 8, a continuous and stable air curtain is formed on the lens surface of the camera 506, thereby effectively preventing dust, water vapor and other pollutants from contacting the lens. At the same time, it can also disperse the tiny particles attached to the lens surface, so that the camera 506 lens is always kept clean, avoiding image blur or recognition failure caused by dust accumulation. During the circulation of the air curtain airflow in the protective shell 610, it can take away the heat generated by the camera 506 during operation, assisting in heat dissipation, thereby helping to maintain the operating temperature of the camera 506 within a reasonable range, extending its service life, and improving the stability of image acquisition;

[0039] In addition, when the protective shell 610 completely covers the button 4, the air curtain airflow is discharged through the exhaust port on the outer wall of the protective shell 610. At this time, through the action of the air guide cover 611, the gas is blown toward the inside of the key slot along the air guide cover 611, and the deposited dust, metal debris and other impurities are completely blown out, so that the surface and surrounding area of ​​the button 4 remain clean, thereby effectively improving the response speed and reliability of the triggering of the button 4, and avoiding the risk of circuit failure caused by the accumulation of impurities, thereby ensuring the accuracy and timeliness of the command input of the fire control system.

[0040] A protection mechanism 7 is provided on one side of the air curtain mechanism 6 .

[0041] See Figures 2 to 3 As shown, a drive motor 502 is installed at one end of the transmission rod 503, and a spring A510 is installed inside the sleeve 508. One end of the spring A510 is fixedly connected to one side of the piston rod 509, and the other end of the spring A510 is fixedly connected to the inside of the sleeve 508.

[0042] See Figure 4 As shown, the outer wall of the transmission rod 503 is provided with two sets of symmetrically arranged sliding grooves, and the active magnet 512 slides inside the sliding grooves.

[0043] See Figures 3 and 4As shown, the adjustment mechanism 8 includes a sleeve A801 ​​installed on one side of the camera 506, a sleeve B802 is installed on the top of the slide rail 501, a connecting pipe 803 is connected between the sleeve A801 ​​and the sleeve B802, a push rod A804 slides inside the sleeve A801, and one end of the push rod A804 is fixedly connected to the side wall of the pressing plate 511, a push rod B805 slides inside the sleeve B802, and a spring B806 is provided inside the sleeve B802.

[0044] See Figure 4 As shown, an annular groove is provided on the outer wall of the active magnet 512, and one end of the push rod B805 slides inside the annular groove. The active magnet 512 and the driven magnet 513 form a non-contact magnetic coupling transmission through the air gap.

[0045] See Figures 3 and 4 As shown, a rotating shaft 514 is installed between the transmission rod 503 and the screw rod 504, and one-way bearings are installed at both ends of the rotating shaft 514. When the pressing is completed and needs to be reset, the driving motor 502 is reversed. At this time, the one-way bearing is locked, and the reverse power of the transmission rod 503 is directly transmitted to the screw rod 504 through the rotating shaft 514, causing it to rotate in the opposite direction, driving the nut seat 505 and the pressing mechanism 5 to accurately reset to the initial position.

[0046] See Figure 5 As shown, the transmission mechanism includes a rotating wheel A605, a rotating wheel B606 and a belt 607. The rotating wheel A605 is sleeved on the outer wall of the transmission rod 503, and the rotating wheel B606 is sleeved on the outer wall of the rotating rod 603. The rotating wheel A605 and the rotating wheel B606 are connected by the belt 607.

[0047] See Figures 5 to 7 As shown, the air outlet of the jet ring 608 is arranged in a ring shape, and the air outlet is arranged parallel to the surface of the camera 506, and a filter plate is installed at the opening of the cylinder 602.

[0048] See Figure 6 As shown, the outer wall of the fixing plate 507 is covered with a protective shell 610 , the outer wall of the protective shell 610 is covered with a flow guide cover 611 , and the outer wall of the protective shell 610 is provided with multiple sets of exhaust ports.

[0049] See Figure 7 As shown, the protective mechanism 7 includes a liquid storage box 701 arranged on the outside of the camera 506, an elastic diaphragm 702 is provided on one side of the liquid storage box 701, and multiple groups of nozzles 703 are installed on the other side of the liquid storage box 701. A connecting rod 704 is installed on the side wall of the pressing plate 511, and an extrusion plate 705 is installed at one end of the connecting rod 704. The extrusion plate 705 is movably connected to the elastic diaphragm 702.

[0050] It should be noted that, in the initial state, the squeezing plate 705 applies a certain pressure to the elastic diaphragm 702 under the preload force of the spring A510, so that the liquid storage box 701 maintains a slightly positive pressure state. When the pressing mechanism 5 performs the button 4 operation, the pressing plate 511 moves toward the button 4 and gradually releases the pressure. During this process, the connecting rod 704 moves synchronously with the pressing plate 511, driving the squeezing plate 705 to move away from the elastic diaphragm 702, so that the elastic diaphragm 702 returns to its initial shape, and the internal pressure of the liquid storage box 701 decreases. When the button 4 operation is completed, the driving motor 502 is reversed, and the pressing mechanism 5 begins to reset. At this time, the pressing plate 511 moves in the opposite direction under the rebound force of the spring A510. The connecting rod 704 pushes the extrusion plate 705 to re-extrude the elastic diaphragm 702. As the deformation of the elastic diaphragm 702 intensifies, the pressure in the liquid storage box 701 increases rapidly, forcing the rust inhibitor inside the liquid storage box 701 to be sprayed out in the form of a fan-shaped spray through multiple groups of nozzles 703. The rust inhibitor quickly forms a dense protective film on the metal surface, effectively isolating the contact between water vapor and corrosive gases in the air and metal parts, thereby slowing down the oxidation rate of metal parts and reducing poor contact problems caused by oxidation, thereby ensuring the stability and effectiveness of the operation of the on-duty robot when working in the fire control room, reducing the risk of operation failure caused by the failure of button 4, and improving the safety and reliability of the overall equipment operation.

[0051] Working Principle: When terminal 1 receives a fire signal, the control system immediately triggers linear motors A2 and B3, driving pressing mechanism 5 to rapidly move within the XY plane of terminal 1 according to a preset program. This allows camera 506, mounted on nut holder 505, to precisely position itself directly above target button 4. At this point, camera 506 quickly activates its image acquisition function, capturing the area surrounding button 4. Using a built-in image recognition algorithm, it analyzes button 4's logo and color characteristics to confirm its function, effectively preventing potential misjudgment by manual operation. Once the target button 4 is confirmed, drive motor 502 activates, rotating transmission rod 503. Because active magnet 512 and transmission rod 503 are slidably connected via a slot, active magnet 512 rotates synchronously with transmission rod 503. By utilizing the magnetic coupling between the active magnet 512 and the driven magnet 513, the driven magnet 513 will be driven to rotate, thereby driving the screw rod 504 to rotate synchronously. As the screw rod 504 rotates, the nut seat 505 that is threaded with the screw rod 504 will move axially along the screw rod 504, thereby driving the camera 506 and the pressing plate 511 to move laterally synchronously. When the pressing plate 511 contacts the target button 4, as the nut seat 505 continues to move, the piston rod 509 will slide into the inside of the sleeve 508, compressing the spring A510 and accumulating elastic potential energy. When the pressing plate 511 contacts the button 4, the spring A510 reduces the impact force through elastic deformation, avoiding damage to the button 4 due to rigid contact, and ensuring that the pressing action is soft and stable.

[0052] As the piston rod 509 further compresses the spring A510, since the button 4 is a mechanical key with a certain pressing resistance, it needs to overcome a certain resistance stroke to be triggered. Therefore, when the compression of the spring A510 reaches the set threshold, the elastic force generated by the spring A510 matches the force required to trigger the button 4. At this time, the pressing plate 511 will accurately press the target button 4 to complete the operation instruction; at the same time, in the process of the piston rod 509 moving into the sleeve 508, the pressing plate 511 drives the push rod A804 to move inside the sleeve A801, so that the push rod A804 compresses the gas inside the sleeve A801, so that the gas enters the sleeve B802 through the connecting pipe 803, so that the gas pushes the push rod B805 to move, further The push rod B805 drives the active magnet 512 to move toward the side away from the driven magnet 513, so that the air gap between the active magnet 512 and the driven magnet 513 gradually expands; when the air gap exceeds a certain threshold, the magnetic coupling effect fails. At this time, although the drive motor 502 continues to rotate, the power cannot be transmitted to the screw rod 504, and the screw rod 504 stops rotating, thereby preventing the button 4 from being over-pressed, squeezed and deformed due to the continuous movement of the nut seat 505, and even damaging the circuit board under the button 4, thereby increasing the service life of the button 4 of the terminal 1, reducing the equipment maintenance and replacement costs, ensuring the stability of the fire control system in frequent use scenarios, avoiding the inability to input commands normally due to damage to the button 4, and improving the efficiency of fire emergency response.

[0053] At the same time, when the driving motor 502 is started and drives the transmission rod 503 to rotate, the transmission rod 503 drives the rotating rod 603 to rotate through the transmission mechanism, and the fan blades 604 on the rotating rod 603 rotate at high speed, forming a negative pressure in the cylinder 602, sucking in the external air, and the sucked air is purified by the filter plate at the opening of the cylinder 602 to remove impurities such as dust and particulate matter, and then transported to the jet ring 608 on the outer wall of the camera 506 through the air pipe A609. Since the air outlet of the jet ring 608 is arranged in a ring shape and is parallel to the surface of the camera 506, the high-speed airflow is sucked in from the jet ring 608. After being ejected from the outlet, a continuous and stable air curtain is formed on the lens surface of the camera 506, thereby effectively preventing dust, water vapor and other pollutants from contacting the lens. At the same time, it can also disperse tiny particles already attached to the lens surface, so that the camera 506 lens is always kept clean, avoiding image blur or recognition failure caused by dust accumulation. During the process of circulating in the protective shell 610, the air curtain airflow can carry away the heat generated by the camera 506 during operation, assisting in heat dissipation, thereby helping to maintain the operating temperature of the camera 506 within a reasonable range, extending its service life, and improving the stability of image acquisition;

[0054] In addition, when the protective shell 610 completely covers the button 4, the air curtain airflow is discharged through the exhaust port on the outer wall of the protective shell 610. At this time, through the action of the air guide cover 611, the gas is blown toward the inside of the key slot along the air guide cover 611, and the deposited dust, metal debris and other impurities are completely blown out, so that the surface and surrounding area of ​​the button 4 remain clean, thereby effectively improving the response speed and reliability of the triggering of the button 4, and avoiding the risk of circuit failure caused by the accumulation of impurities, thereby ensuring the accuracy and timeliness of the command input of the fire control system.

[0055] In addition, in the initial state, the squeezing plate 705 applies a certain pressure to the elastic diaphragm 702 under the preload force of the spring A510, so that the liquid storage box 701 maintains a slightly positive pressure state. When the pressing mechanism 5 performs the button 4 operation, the pressing plate 511 moves toward the button 4 and gradually releases the pressure. During this process, the connecting rod 704 moves synchronously with the pressing plate 511, driving the squeezing plate 705 to move away from the elastic diaphragm 702, so that the elastic diaphragm 702 returns to its initial shape, and the internal pressure of the liquid storage box 701 decreases. When the button 4 operation is completed, the driving motor 502 reverses, and the pressing mechanism 5 begins to reset. At this time, the pressing plate 511 moves in the opposite direction under the rebound force of the spring A510. The extrusion plate 705 is pushed by the connecting rod 704 to re-extrude the elastic diaphragm 702. As the deformation of the elastic diaphragm 702 intensifies, the pressure in the liquid storage box 701 increases rapidly, forcing the rust inhibitor inside the liquid storage box 701 to be sprayed out in the form of a fan-shaped spray through multiple groups of nozzles 703. The rust inhibitor quickly forms a dense protective film on the metal surface, effectively isolating the contact between water vapor and corrosive gases in the air and metal parts, thereby slowing down the oxidation rate of metal parts and reducing poor contact problems caused by oxidation, thereby ensuring the stability and effectiveness of the operation of the on-duty robot when working in the fire control room, reducing the risk of operation failure caused by the failure of button 4, and improving the safety and reliability of the overall equipment operation.
