Description

Technical Field

[0001] The invention relates to the technical field of alarms, and in particular to a production safety detection alarm. Background Art

[0002] A production safety detection alarm is a device used to monitor and detect potential hazardous factors in the production environment, and it will sound an alarm when an abnormal situation occurs, so that timely measures can be taken to ensure production safety. A pipeline gas leak alarm is a device used to monitor and detect gas leaks in pipelines. It can detect gas leaks in time and sound an alarm to remind relevant personnel to take corresponding safety measures. This alarm usually uses a sensor to detect gas concentration. When the concentration exceeds the set threshold, it will trigger the alarm system. In the fields of industry, chemical industry, petroleum, natural gas, etc., pipeline gas leak alarms are widely used to ensure the safety of personnel and equipment.

[0003] In some industries, such as industry, chemical industry, petroleum, and natural gas, pipelines are used to transport various gases, including some toxic gases, which may cause harm to human health. Therefore, gas leak alarms are installed to detect whether there is gas leakage at the pipeline connection. However, for outdoor pipelines in chemical plants, gas leak alarms are generally installed near potential leakage-prone areas, such as elbows, reducers, and cuts. If the gas leak is relatively small or occurs far away from the alarm, it will take longer for the leaked gas to diffuse into the alarm range, delaying the alarm response time.

DETAILED DESCRIPTION

[0026] 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.

[0027] Embodiment 1

[0028] See also Figure 1-7 The present invention provides a technical solution: a production safety detection alarm, including an alarm body 1, a warning light 2 is fixedly connected to one side of the alarm body 1, and a probe 3 is fixedly connected to the lower part of the alarm body 1; a detection chamber 4, the detection chamber 4 is located outside the probe 3, the detection chamber 4 can wrap the pipeline and separate multiple collection chambers 5; a transmission mechanism 6, the transmission mechanism 6 is located on the inner wall of the detection chamber 4, the transmission mechanism 6 can circulate and send the gas in multiple areas of the detection chamber 4 to the probe 3 position one by one for detection. When in use, the installer fixes the detection chamber 4 to the outside of the pipeline, and wraps the pipeline surface through the detection chamber 4, so as to detect the gas in the detection chamber 4. While the pipeline surface is insulated and heat-insulated, the toxic gas leaking from the pipeline can also be isolated to prevent the gas from directly leaking into the surrounding air, and the transmission mechanism 6 can circulate the gas from multiple areas in the detection chamber 4 to the probe 3 position one by one for detection. When the probe 3 detects a gas leak, the warning light 2 alarms to help remind maintenance personnel to come for maintenance, thereby avoiding the situation where the gas leak is relatively small or the leak location is far from the alarm location, and the dissipated toxic gas takes a longer time to diffuse to the probe 3 position, and can facilitate the staff to quickly find the gas leak location, which is convenient for maintenance personnel to locate the damaged pipeline.

[0029] The detection chamber 4 includes a thermal insulation sponge 40 for wrapping the pipeline, and a plurality of separation semi-rings 41 are fixedly connected to the outside of the thermal insulation sponge 40, and the plurality of separation semi-rings 41 are combined into a circular ring in pairs, and a sealing semi-cylinder 42 is fixedly connected between the two separation semi-rings 41 close to the probe 3, and the two sealing semi-cylinders 42 can be combined into a cylinder, and a fluoroplastic film 43 is fixedly connected to the outside of the remaining separation semi-rings 41, and a one-way valve 44 is fixedly connected to the surface of the fluoroplastic film 43. When installing the detection chamber 4, first use a tape measure or a measuring tool to measure the diameter and length of the pipeline in order to prepare a thermal insulation sponge 40 of a suitable size, and according to the measurement results, use a knife or scissors to cut the thermal insulation sponge 40 into a suitable length and width to ensure that it can completely cover the surface of the pipeline, and then use thermal insulation tape and stainless steel tape to fix the cut thermal insulation sponge 40 on the surface of the pipeline, and after the thermal insulation sponge 40 is attached to the surface of the pipeline, it cooperates with the thermal insulation of the pipeline surface. Insulation, then apply sealant under the sealing half cylinder 42 fixed with the probe 3, then clamp the sealing half cylinder 42 above the sealing sponge, and then apply sealant on the surface of the other half of the sealing half cylinder 42, and then clamp it from the bottom of the pipeline to the top, so that the two sealing half cylinders 42 can be combined into a cylinder to cooperate to form the detection area of ​​the probe 3. Similarly, the surfaces of multiple separation half rings 41 are coated with sealant, and then clamped on the surface of the insulation sponge 40 at a fixed interval. The upper and lower separation half rings 41 are combined into a circular ring, and the fluoroplastic film 43 is fixed on the outside of the circular ring formed by the separation half rings 41, so that the detection chamber 4 is divided into multiple collection chambers 5, and the fluoroplastic film 43 on the outside of the circular ring formed by the separation half rings 41 is wrinkled, so that when the transmission mechanism 6 inhales air into the monitoring area, the fluoroplastic film 43 can be concave, and when the pipeline gas leaks, the fluoroplastic film 43 can bulge, which is convenient for the staff to quickly find the gas leakage location.

[0030] The transmission mechanism 6 includes a plurality of transmission tubes 60 located on the inner wall of the detection chamber 4, and the plurality of transmission tubes 60 are respectively connected to the plurality of separation semi-rings 41. A connection semi-ring 61 is fixedly connected to the inner wall of the sealing semi-cylinder 42, and a plurality of connecting holes 62 are provided on the surface of the connection semi-ring 61. The connection semi-ring 61 is fixedly connected to the transmission tube 60, and the connecting holes 62 are connected to the transmission tube 60. A fixed semi-ring 63 is fixedly connected to the inner wall of the sealing semi-cylinder 42, and an air inlet 64 is provided on the inner wall of the fixed semi-ring 63. A transmission member 65 capable of sequentially delivering the gas in different areas of the detection chamber 4 into the air inlet 64 is provided between the connection semi-ring 61 and the fixed semi-ring 63. When installing, the two connection semi-rings are connected to the detection chamber 4. The ring 61 and the fixed half ring 63 are engaged with the surface of the thermal insulation sponge 40 and fixed by sealant. During daily operation, the alarm body 1 can be connected with the connecting hole 62 and the air inlet 64 in sequence through the arranged transmission member 65. Therefore, when the transmission member 65 is connected with the connecting hole 62, the gas in the corresponding area can be drawn into the transmission member 65 through the transmission pipe 60 connected with the connecting hole 62. When the transmission member 65 is connected with the air inlet 64, the transmission member 65 can send the gas in the transmission member 65 to the position of the probe 3 through the air inlet 64, so that the probe 3 can timely monitor the pipeline leakage in each area of ​​the detection chamber 4.

[0031] The transmission member 65 includes a transmission block 66 located between the connecting semi-ring 61 and the fixed semi-ring 63. The inner wall of the transmission block 66 is provided with a gas transmission hole 67. The transmission block 66 is fixedly connected to the limiting rings 68 on both sides. The inner walls of the connecting semi-ring 61 and the fixed semi-ring 63 are respectively provided with limiting grooves 69 that can be rotatably connected to the limiting rings 68. The inner wall of the gas transmission hole 67 is provided with a transfer member 610 that can inhale and exhaust the inner wall of the gas transmission hole 67. The outer side of the transmission block 66 is provided with a transfer member that can drive the transmission block 66 to move between the connecting semi-ring 61 and the fixed semi-ring 63. The driving member 611 rotates between the fixed half ring 63, and the driving member 611 is connected to the transfer member 610. When the transmission member 65 is working, the driving member 611 drives the transmission block 66 to rotate between the connecting half ring 61 and the fixed half ring 63, so that the gas delivery hole 67 can be connected with the connecting hole 62 and the air inlet in turn. When the gas delivery hole 67 is connected with the connecting hole 62, the transfer member 610 can suck air into the connecting hole 62, so that the gas in the corresponding area can be transferred through the transmission pipe 60 connected with the connecting hole 62. The air is sucked into the air delivery hole 67, and the fluoroplastic film 43 on the surface of the detection chamber 4 area where the air is sucked away is sunken. The sunken fluoroplastic film 43 allows the outside air to slowly enter through the one-way valve 44, so that the sunken fluoroplastic film 43 is gradually restored. As the transmission block 66 rotates, the transmission block 66 drives the limit ring 68 to rotate in the limit groove 69, and the air delivery hole 67 of the transmission block 66 is separated from the connecting hole 62, and the connecting hole 62 is blocked at one end close to the transmission block 66. When 67 is connected with the air inlet, the driving member 611 controls the transmission block 66 to stop sliding, and the transfer member 610 sends the gas in the air delivery hole 67 into the area where the probe 3 is located in the sealing semi-cylinder 42 through the air inlet 64, and detects whether the sent gas contains toxic gas through the probe 3. When the gas is discharged, the driving member 611 drives the transmission block 66 to move again, so that the transmission block 66 can be connected with different connecting holes 62 and the air inlet in turn, which is convenient for the probe 3 to detect various areas in the detection chamber 4.

[0032] The driving member 611 includes a rotating ring 612 fixedly connected to the outer side of the transmission block 66, and the rotating ring 612 is slidably connected to the surfaces of the connecting half ring 61 and the fixed half ring 63 respectively. A transmission gear ring 613 is fixedly connected to the outer side of the rotating ring 612, and a transmission gear 614 is meshed on the outer side of the transmission gear ring 613. One end of the transmission gear 614 is rotatably connected to the inner wall of the sealing half cylinder 42, and the other end of the transmission gear 614 is fixedly connected to an impeller 615. A concave arc 625 is provided on the side of the impeller 615 close to the jet pipe 616 to facilitate rotation when blown by airflow. The jet pipe 616 is located on the outer side of the impeller 615, and one end of the jet pipe 616 is fixedly connected to an air pump 617. The air pump 617 is fixedly connected to the inner wall of the sealing half cylinder 42, and the jet pipe 616 is connected to the transfer member 610. The inner wall of the air delivery hole 67 is provided with a control member that can control the operation of the air pump 617 618. When the driving member 611 is working, the airflow generated by the air pump 617 blows the impeller 615 to rotate through the air jet pipe 616, and the impeller 615 drives the transmission gear 614 to rotate, the transmission gear 614 drives the transmission gear ring 613 to rotate, the transmission gear ring 613 drives the rotating ring 612 to rotate, and the rotating ring 612 drives the inner transmission block 66 to rotate, so that the air delivery hole 67 of the transmission block 66 can be connected with the connecting hole 62 and the air inlet hole 64 in sequence. When the air delivery hole 67 of the transmission block 66 is connected with the air inlet hole 64, the control member 618 can control the air pump 617 to stop discharging air, and the impeller 615 to stop rotating, so that the transmission block 66 stops sliding, so that the transfer member 610 can send the gas in the air delivery hole 67 of the transmission block 66 through the air inlet hole 64 to the vicinity of the probe 3 to cooperate with the detection of the probe 3.

[0033] The control component 618 includes a pressure sensor 619 located on the inner wall of the gas delivery hole 67, and a relay 620 located on the outside of the air pump 617. The relay 620 is fixedly connected to the inner wall of the sealing semi-cylinder 42, and the relay 620 is connected to the pressure sensor 619 and the air pump 617 respectively. When in use, the pressure sensor 619 is installed on the inner wall of the gas delivery hole 67, the pressure sensor 619 is connected to the relay 620, and then the relay 620 is connected to the air pump 617. Then, according to needs, the pressure threshold for starting and stopping the air pump 617 is determined. When the pressure detected by the pressure sensor 619 is lower than the set minimum threshold, the pressure sensor 619 sends a signal to the relay 620, and the relay 620 disconnects the power supply of the air pump 617 and stops the air pump 617. When the pressure detected by the pressure sensor 619 is greater than the set maximum threshold, the relay 620 closes the power supply of the air pump 617, and the air pump 617 starts working again. The transmission block 66 slides again to cooperate and drive the transmission block 66 to connect with different connecting holes 62 and air inlet holes 64 in sequence.

[0034] The transfer member 610 includes a piston plate 621 slidably connected to the inner wall of the gas delivery hole 67, one end of the piston plate 621 is fixedly connected to a compression spring 622, one end of the compression spring 622 is fixedly connected to the inner wall of the transmission block 66, the inner wall of the rotating ring 612 is provided with a connecting groove 623, the connecting groove 623 is connected to the gas delivery hole 67, the outer side of the rotating ring 612 is slidably connected to an air inlet box 626, the air inlet box 626 and the rotating ring 612 can maintain a seal when they rotate relative to each other, thereby preventing the suction pipe 612 from being blocked. The gas entering the air inlet box 626 can enter the connecting groove 623. The air inlet box 626 is fixedly connected to the surface of the sealing half cylinder 42. The outer side of the air inlet box 626 is fixedly connected with an air intake pipe 624. The inner diameter of the air intake pipe 624 is smaller than the inner diameter of the air injection pipe 616. One end of the air intake pipe 624 is connected to the connecting groove 623. The end of the air intake pipe 624 away from the connecting groove 623 is connected to the air injection pipe 616. When the transfer member 610 is working, the airflow generated by the air pump 617 passes through the air injection pipe 616. 6 is blown toward the impeller 615, and the inner diameter of the air intake pipe 624 is smaller than that of the air jet pipe 616. Therefore, when the high-speed airflow in the air jet pipe 616 passes through, the airflow in the air delivery hole 67 will enter the air jet pipe 616 through the connecting groove 623 and the air intake pipe 624 due to the low pressure at the location where the flow rate is high, resulting in inconsistent pressure on both sides of the piston plate 621. The piston plate 621 slides along the inner wall of the air delivery hole 67 and squeezes the compression spring 622, and the piston plate 621 is in the air delivery hole 67. The wall slides to cooperate with the air flow in the detection chamber 4 to be sucked into the air delivery hole 67. When the air pump 617 stops working, the air flow enters the air delivery hole 67 through the suction pipe 624 and the connecting groove 623. The pressure in the air delivery hole 67 increases, and the compression spring 622 in the compressed state is reset to cooperate with pushing the piston plate 621 to slide along the inner wall of the air delivery hole 67. The piston plate 621 pushes the air flow in the air delivery hole 67 to cooperate with sending the air flow to be detected into the position of the probe 3 to cooperate with the probe 3 for detection.

[0035] According to the above embodiment, embodiment 2

[0036] like Figure 8 In the second embodiment, other structures remain unchanged. The difference from the first embodiment is that the inner diameter of the end of the jet pipe 616 close to the impeller 615 is tapered, so that when the airflow is ejected, the gas will flow in from the large inner diameter to the small inner diameter. At this time, the flow rate of the gas will be increased. According to the Bernoulli principle, the faster the flow rate, the smaller the pressure at the position. When the airflow blows the impeller 615 to rotate, the airflow in the suction pipe 624 will flow into the jet pipe 616, so that the pressure on one side of the piston plate 621 in the transmission block 66 is reduced, so that the piston plate 621 slides in the air delivery hole 67 to cooperate with the extraction of air in the connecting hole 62, reducing the flow rate requirement of the airflow ejected by the air pump 617, and the pressure generated by the air pump 617 is reduced, thereby reducing the working energy consumption of the air pump 617.
