Description

Technical Field

[0001] The invention belongs to the technical field of safety interlock protection detection, and in particular is a burner safety interlock protection detection device integrated with the Internet of Things. Background Art

[0002] The IoT-integrated burner safety interlock protection detection equipment is an advanced safety device. Through the combination of IoT technology and safety interlock protection mechanism, it realizes real-time monitoring and intelligent management of burners. The equipment has significant advantages in improving safety, improving efficiency, reducing costs and enhancing reliability, and is widely used in various places that require high-safety burners.

[0003] For example, the invention with publication number CN115407741A relates to a steam boiler detection technology field, which is a steam boiler safety interlock detection device and detection method. The former includes a control unit, an intermediate relay of the device, a micro-ampere signal transmitting unit, and an input-output unit. The input-output unit is respectively connected to the control unit, the intermediate relay of the device, and the micro-ampere signal transmitting unit. The coil of the intermediate relay of the device is connected to the control unit. The micro-ampere signal transmitting unit is respectively connected to the control unit and the input-output unit. The control unit is respectively connected to the intermediate relay of the device, the micro-ampere signal transmitting unit, and the input-output unit. The present invention can check the automation instrument signal link and PLC analog channel of the steam boiler, thereby improving the efficiency of self-inspection work; it can check the ignition, main fire, and flameout safety time to complete the self-inspection of the steam boiler; it can simulate the ignition of the steam boiler PLC, and perform program trial and error by interfering with various signals during the process, thereby improving the operating efficiency of the boiler; When the above-mentioned device is in use, the detection purpose is achieved by connecting the sensor to each socket of the equipment. However, when the above-mentioned device is in use, since the burner will generate vibrations during operation, especially large burners in industrial environments, the vibrations during operation may be relatively strong. These vibrations will be transmitted to the sensor and its connector, and long-term vibration may cause the connector and the device interface to gradually loosen, thereby causing unstable or interrupted signal transmission. For example, a loose connector of the flame sensor may make it impossible for the device to accurately receive the signal of whether the flame exists, thereby causing the burner control system to misjudge. If the signal cannot be transmitted to the device in time when the flame is extinguished, the safety interlock mechanism may not be triggered, causing the burner to continue to spray oil or gas, causing serious accidents such as fire or explosion. Therefore, an Internet of Things integrated burner safety interlock protection detection device is proposed to solve the problems raised in the background technology. Summary of the invention

[0014] Preferably, the second guide groove consists of a transverse groove and an oblique groove, and a gap is left between the side wall of the baffle and the interface.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention prevents the sensor joint and the device from loosening and affecting the detection effect by cooperating between structures such as a moving component, a limit block, a baffle and a second guide groove.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an IoT-integrated burner safety interlock protection detection device, comprising a detection box 1, one side of the detection box 1 is provided with three interfaces 2, and the interior of the detection box 1 is movably connected with a moving component 3; The moving assembly 3 includes a square block 31, and two groups of first guide grooves 32 are symmetrically opened on the surface of the square block 31. The first guide groove 32 is movably connected with a first round rod 33. Three limit blocks 4 are fixedly connected to the surface of the first round rod 33, and a baffle 5 is movably connected inside the limit block 4. Two sets of second guide grooves 6 cooperating with the baffle 5 are opened on the inner wall of the detection box 1. Two clamping components 7 are symmetrically arranged on one side of the detection box 1. A rotating component 8 is movably connected inside the detection box 1, and a display screen 9 is arranged on one side of the detection box 1.

[0021] The above scheme is adopted: the square block 31 is moved toward the direction of the clamping assembly 7, so that the first round rod 33 slides along the track of the first guide groove 32, and because the two first guide grooves 32 are in opposite directions, the two first round rods 33 drive the limit blocks 4 thereon to move toward each other, and when the limit blocks 4 move, the baffle plate 5 is driven to slide along the track of the second guide groove 6, so that the baffle plate 5 slides along the track of the second guide groove 6 toward the direction of the interface 2, and then the side wall of the baffle plate 5 abuts against the outer wall of the sensor connector, and squeezes the connector to move toward the direction of the interface 2, thereby preventing the sensor connector and the device from loosening, and effectively ensuring the detection effect; The display screen 9 is set up so that, during the operation of the burner, a large amount of key safety interlock related data, such as temperature, pressure, flame state, fuel flow, etc., will be generated. The display screen 9 can intuitively display these data collected by the sensor in real time, so that the operator can directly see these important information on site without using complicated tools or other equipment. For example, during the start-up phase of the burner, the operator can observe the rise in temperature and pressure through the display screen 9 to ensure that the combustion process is started within the normal parameter range.

[0022] like Figure 1 and Figure 8 As shown, the clamping assembly 7 includes a clamping plate 71, the bottom of which is fixedly connected to a second round rod 72, and semicircular grooves are provided on opposite sides of the two clamping plates 71, and a gasket 73 is fixedly connected inside the semicircular groove of the clamping plate 71, and the gasket 73 is made of rubber material and is located directly in front of the interface 2.

[0023] The above solution is adopted: the gasket 73 is made of rubber material. Its function is that the burner will generate vibration during operation, which may cause the sensor cable and the connector to be subjected to a certain impact force. The rubber material has good elasticity and buffering properties, and can absorb and disperse the energy generated by these vibrations. For example, when the vibration of the burner is transmitted to the connector through the cable, the rubber can play a buffering role, reducing the impact of the vibration on the connection, thereby reducing the possibility of loosening the joint. At the same time, the rubber material can also fill the small gap between the clamping plate 71 and the sensor cable, thereby improving the fixing effect of the cable.

[0024] like Figure 3 , Figure 5 and Figure 8As shown, the rotating assembly 8 includes a rotating drum 81, both ends of the surface of the rotating drum 81 are provided with arc grooves 82, and the two arc grooves 82 are in opposite directions. A gear 83 is fixedly connected to the middle of the rotating drum 81, and one end of the second round rod 72 away from the clamping plate 71 moves inside the arc groove 82. The inner wall of the detection box 1 is provided with a straight groove 74 for limiting the second round rod 72. A threaded rod 84 is threadedly connected to the side of the detection box 1 close to the display screen 9. A cross groove is provided at one end of the rotating drum 81, and a cross block that moves inside the cross groove is provided at one end of the threaded rod 84. The other end of the threaded rod 84 passes through the outer wall of the detection box 1 and extends to the outside of the detection box 1.

[0025] The above scheme is adopted: the two arc grooves 82 are oriented in opposite directions, so that when the rotating drum 81 rotates, the two second round rods 72 can move toward each other along the tracks of the two arc grooves 82 under the limiting action of the straight groove 74, and then the two clamping plates 71 are driven by the second round rods 72 to abut against each other. After the clamping plates 71 abut, the gasket 73 is driven to overlap with the cable of the sensor connector, and then the cable is fixed inside the semicircular groove of the clamping plate 71, so as to limit the cable, thereby improving the fixing effect of the sensor connector, thereby improving the overall detection accuracy of the equipment; A cross groove is provided inside the rotating drum 81, and its function is that the cross groove limits the cross block on the threaded rod 84 circumferentially, so that the rotating drum 81 can be driven to rotate when the threaded rod 84 rotates. At the same time, the threaded rod 84 is threadedly connected to the detection box 1, so that the threaded rod 84 will move toward the inside or outside of the detection box 1 during the rotation process. At this time, the cross block on the threaded rod 84 will slide inside the cross groove, thereby ensuring the normal operation of the device.

[0026] like Figures 2 to 7 As shown, the two first guide grooves 32 are in opposite directions, and the two ends of the first round rod 33 pass through the upper and lower sides of the square block 31. The inner wall of the detection box 1 is provided with a slide groove for limiting the first round rod 33 in the horizontal direction. The inner wall of the detection box 1 is provided with a square groove matching the square block 31. The bottom end of the square block 31 is fixedly connected with a tooth plate 34, and the tooth plate 34 is meshed with the gear 83. When the square block 31 moves, it drives the two first round rods 33 to move in opposite directions along the trajectories of the two first guide grooves 32 respectively. The upper and lower ends of the baffle 5 are provided with protrusions, and the protrusions on the baffle 5 are movably connected to the inside of the second guide groove 6. A block that is movable inside the limit block 4 is provided on one side of the baffle 5. The second guide groove 6 consists of a transverse groove and an oblique groove, and a gap is left between the side wall of the baffle 5 and the interface 2.

[0027] The above scheme is adopted: a slide groove and a square groove are opened on the inner wall of the detection box 1, and its function is that when the rotating drum 81 drives the gear 83 to rotate, the square groove is opened so that the tooth plate 34 can only drive the square block 31 to move in a straight line along the trajectory of the square groove. At the same time, the slide groove limits the upper and lower ends of the first round rod 33, so that when the square block 31 moves, the first round rod 33 can only drive the limit block 4 to move horizontally and linearly under the action of the horizontal limit of the slide groove.

[0028] The working principle and use process of the present invention are as follows: First, the operator inserts the connectors of various sensors into the interior of the interface 2 respectively. When the insertion is completed, the arc groove 82 and the gear 83 in the middle thereof are driven to rotate by rotating the threaded rod 84. While the gear 83 rotates, it is meshed with the tooth plate 34, thereby driving the square block 31 to move toward the clamping plate 71 through the tooth plate 34, so that the two first round rods 33 move toward each other along the tracks of the two first guide grooves 32 under the action of the slide groove limit. While moving, the limit block 4 fixedly connected to the outside is driven to move in the same direction, and the two baffles 5 are driven to move toward each other through the limit block 4, so that the protrusions at the upper and lower ends of the baffle 5 slide along the track of the second guide groove 6, and then the protrusion at the top of the baffle 5 slides along the track of the transverse groove of the second guide groove 6 to the inside of the inclined groove, so that the protrusion moves toward the direction of the interface 2 along the track of the inclined groove, so that the side wall of the baffle 5 abuts against the outer wall of the sensor connector, thereby squeezing the connector, and making the connection between the connector and the interface 2 tighter; When the rotating drum 81 rotates, it also drives one end of the second round rod 72 to slide along the trajectory of the arc groove 82. Since the second round rod 72 is limited by the straight groove 74, the second round rod 72 can only drive the clamping plate 71 to move in a straight line along the trajectory of the straight groove 74 when sliding, thereby driving the two clamping plates 71 to move toward each other. When the side walls of the two clamping plates 71 abut against each other, at this time, the clamping plate 71 drives the gasket 73 to abut against the cable on the sensor connector, and through the abutment of the two clamping plates 71, the two semicircular grooves overlap to form a circular hole, thereby limiting the cable, thereby improving the stability of the overall operation of the equipment and thus improving the detection effect.
