Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and specifically to a gas monitoring device for hazardous chemical storage. Background Technique

[0002] At present, with the continuous improvement of people's living standards, the quantity of hazardous chemicals generated is increasing continuously, and the usage frequency of hazardous chemical warehouses is getting higher and higher, resulting in a shortage in the hazardous chemical storage market and a serious shortage of warehouses. If warehouse managers operate improperly or there are defects in the management of hazardous material warehouses, it is easy to trigger tragic accidents. Therefore, a gas concentration monitoring device is needed to carry out monitoring work.

[0003] Publication No. CN219533088U discloses a gas monitoring device for hazardous chemical storage. The hazardous chemicals are monitored by a gas monitoring body. When hazardous chemicals are detected, an alarm is used to alert the staff. When it is necessary to disassemble and repair the gas monitoring body, the rotating plate is rotated. The rotating plate drives the left - right screw rod to rotate. The left - right screw rod drives the nut sleeve to move outwards. The nut sleeve drives the clamping plate to move outwards. The movable groove in the bearing plate cooperates with the clamping plate to move outwards. The clamping plate drives the clamping rod to move outwards. When the clamping rod moves out of the clamping groove, the gas monitoring body can be disassembled and repaired. Through the operation of the hydraulic cylinder, the hydraulic cylinder drives the moving plate to move upwards. The chute in the movable box cooperates with the moving plate to move upwards. The moving plate drives the push rod to move upwards. The push rod drives the bearing plate to move upwards. The bearing plate can drive the gas monitoring body to adjust the height. In this way, the gas monitoring device has a better effect when in use. However, the following problems still exist in the actual use of this patent:

[0004] Although the gas monitoring device for hazardous chemical storage drives the clamping plate to move outwards through the nut sleeve, the movable groove in the bearing plate cooperates with the clamping plate to move outwards, and the clamping plate drives the clamping rod to move outwards. When the clamping rod moves out of the clamping groove, the gas monitoring body can be disassembled and repaired. However, since some hazardous chemical gases have a density greater than air and some have a density less than air, there will be a phenomenon of hazardous chemical gas floating or precipitating. It is not possible to carry out targeted monitoring according to the density characteristics of hazardous chemical gases, which will have a certain impact on the accuracy of the monitoring results. At the same time, it is not possible to treat a small amount of leaked hazardous chemical gas, which is not conducive to the safety of monitoring.

[0005] Therefore, a gas monitoring device for hazardous chemical storage is proposed to solve the problems raised above. Summary of the Invention

[0006] The object of the present invention is to provide a gas monitoring device for the storage of hazardous chemicals, so as to solve the problems raised in the above background technology. Since some hazardous chemical gases have a density greater than that of air and some have a density less than that of air, there will be a phenomenon that the hazardous chemical gases float or precipitate.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: For this gas monitoring device for hazardous chemical storage, under the action of the opening and closing rotating rod, the opening and closing sliding sleeve drives the opening and closing closing plate to move relatively, and it can open or close the first one-way valve at different positions as needed, which is convenient for monitoring the hazardous chemical gas and finding the leakage source of the hazardous chemical storage tank at the same time. Inert materials such as drying stones or soda ash are placed inside the gas treatment cylinder. Through the inert materials, a small amount of leaked hazardous chemical gas can be absorbed to prevent it from flowing into the restricted space and causing potential safety hazards. The specific content is as follows:

[0022] 1. By setting up a monitoring mechanism, not only can the driving motor on one side inside the mobile vehicle drive the driving roller to rotate, thereby enabling the movement of the entire gas monitoring device, facilitating the monitoring of gas leakage during the storage of hazardous chemicals. At the same time, the first air extraction fan inside the extraction space is started to extract air from the inclined extraction port and the vertical extraction port, and enters the monitoring box through the telescopic connecting pipe. The monitoring equipment is used to monitor the gas during the storage of hazardous chemicals, and it can monitor the hazardous chemical gas with a density greater than that of air. Since the gas density is greater than that of air, the gas will sink and accumulate at the bottom, and it can monitor the hazardous chemical gas with a density greater than that of air. By starting the lifting motor to drive the lifting rotating rod and the bevel gear transmission assembly to rotate, the bevel gear transmission assembly drives the lifting screw rod to rotate. At the same time, the lifting screw sleeve drives the monitoring box to move up and down. By adjusting the height of the monitoring box, it can monitor the air near the valve of the hazardous material storage tank, avoiding leakage at the valve and causing certain hazards. By driving the unlocking connecting rod and the engaging sliding plate with the unlocking plate to squeeze the first engaging spring, when the engaging sliding plate is engaged with the engaging groove, the installation of the mounting plate can be realized, facilitating the installation and maintenance of the monitoring equipment. By starting the flipping motor, the monitoring box can be driven to rotate in the vertical direction. At the same time, the rotating motor is started to drive the rotating worm to rotate. Utilizing the meshing connection between the rotating worm and the rotating worm wheel, the rotating worm wheel drives the rotating connecting pipe and the extraction cylinder to rotate. By driving the second extraction fan to rotate with the extraction motor, the extraction of the upper air can be realized, and it can monitor the hazardous chemical gas with a density smaller than that of air and floating on the top of the storage tank, improving the comprehensiveness of the hazardous chemical gas monitoring. Through the elastic force of the first valve expansion rod and the first valve spring inside the first one-way valve, the first valve piston is brought into close contact with the first engaging block, enabling the one-way flow of gas and preventing gas overflow from affecting the monitoring accuracy. By starting the electric expansion rod to drive the closing sliding disc to slide inside the closing sliding sleeve, under the action of the opening and closing rotating rod, the closing sliding sleeve drives the opening and closing closing plate to move relatively, and different positions of the first one-way valve can be opened or closed as needed, facilitating the monitoring of hazardous chemical gas and finding the leakage source of the hazardous chemical storage tank at the same time;

[0023] 2. By setting up a gas treatment mechanism, not only can inert materials such as drying stones or soda ash be placed inside the gas treatment cylinder, and through the inert materials, a small amount of leaked hazardous chemical gas can be absorbed to prevent it from flowing into the restricted space and causing potential safety hazards. By starting the mixing motor to drive the rotation of the mixing driving gear, and using the meshing connection between the mixing driving gear and the mixing driven gear, not only can the self-rotation of the first mixing auger and the second mixing auger be realized, facilitating the mixing of the inert materials and the hazardous chemical gas, but also by using the meshing connection between the mixing driven gear and the meshing tooth disc, the revolution of the second mixing auger can be realized, thereby achieving the full mixing of the inert materials and the hazardous chemical gas, facilitating the full absorption of the leaked hazardous chemical gas. By setting up a second check valve and using the elastic force of the second valve expansion rod and the second valve spring inside it, the second valve piston can be made to fit and connect with the second engaging block, preventing external air from entering the inside of the gas treatment cylinder and thus affecting the inert materials.

At the same time, the first exhaust fan 109 inside the exhaust space 105 is started to draw air into the monitoring box 119 through the inclined exhaust port 106 and the vertical exhaust port 107, and through the telescopic connecting pipe 110. The monitoring equipment 122 is used to monitor the gas during the storage of hazardous chemicals, and can monitor the hazardous chemical gas with a density greater than that of air. Since the gas density is greater than that of air, the gas will sink and accumulate at the bottom, and the hazardous chemical gas with a density greater than that of air can be monitored. By starting the lifting motor 113 to drive the lifting rotating rod 114 and the bevel gear transmission assembly 115 to rotate, the bevel gear transmission assembly 115 drives the lifting threaded rod 116 to rotate. At the same time, the lifting threaded sleeve 117 drives the monitoring box 119 to move up and down. By adjusting the height of the monitoring box 119, the air near the valve of the hazardous material storage tank can be monitored to avoid leakage at the valve and cause certain harm. By driving the unlocking connecting rod 124 and the engaging sliding plate 125 to squeeze the first engaging spring 126 through the unlocking plate 123, when the engaging sliding plate 125 is in engaging connection with the engaging groove 120, the installation of the mounting plate 121 can be realized, facilitating the installation and maintenance of the monitoring equipment 122.

[0043] Secondly, starting the flipping motor 118 can drive the monitoring box 119 to rotate in the vertical direction. At the same time, starting the rotating motor 128 drives the rotating worm 129 to rotate. By utilizing the meshing connection between the rotating worm 129 and the rotating worm gear 130, the rotating worm gear 130 drives the rotating connecting pipe 131 and the extraction cylinder 132 to rotate. Starting the extraction motor 133 drives the second extraction fan 134 to rotate, which can achieve the extraction of the upper air and monitor the hazardous chemical gas with a density smaller than air and floating on the top of the storage tank, improving the comprehensiveness of the hazardous chemical gas monitoring. Through the elastic force of the first valve expansion rod 138 and the first valve spring 139 inside the first one-way valve 135, the first valve piston 140 is in fit connection with the first engaging block 136, enabling the one-way flow of gas and preventing gas overflow from affecting the monitoring accuracy. By starting the electric telescopic rod 142 to drive the closing sliding disc 143 to slide inside the closing sliding sleeve 141, under the action of the opening and closing rotating rod 147, the opening and closing sliding sleeve 145 drives the opening and closing closing plate 148 to move relatively, and different-position first one-way valves 135 can be opened or closed as needed, facilitating the monitoring of hazardous chemical gas and finding the leakage source of the hazardous chemical storage tank at the same time.

[0044] Finally, inert materials such as drying stones or soda ash are placed inside the gas treatment cylinder 201. The inert materials can absorb a small amount of leaked hazardous chemical gas, preventing it from flowing into the restricted space and causing potential safety hazards. By starting the mixing motor 206 to drive the mixing driving gear 207 to rotate, and utilizing the meshing connection between the mixing driving gear 207 and the mixing driven gear 208, not only can the self-rotation of the first mixing auger 210 and the second mixing auger 213 be achieved, facilitating the mixing of the inert materials and the hazardous chemical gas, but also by utilizing the meshing connection between the mixing driven gear 208 and the meshing gear disc 209, the revolution of the second mixing auger 213 can be achieved, thus realizing the full mixing of the inert materials and the hazardous chemical gas and facilitating the full absorption of the leaked hazardous chemical gas. By setting the second one-way valve 214 and utilizing the elastic force of the second valve expansion rod 217 and the second valve spring 218 inside it, the second valve piston 219 can be in fit connection with the second engaging block 215, preventing external air from entering the inside of the gas treatment cylinder 201 and thus affecting the inert materials.
