DETAILED DESCRIPTION
[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0038] Example 1: Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11 A safety protection device for chemical electrical construction includes a hanging basket 1 installed on a crane, a cavity is provided on the side panel of the hanging basket 1, and the hanging basket 1 is a cylindrical body with both the bottom and the sides sealed. It also includes: an air pump 3, fixedly connected to the crane, and an exhaust pipe 301 is connected to the air outlet end of the air pump 3; multiple groups of inflatable air bags 2, which are annularly fixedly connected to the cavity of the hanging basket 1, and multiple groups of air outlets 201 are provided on the inflatable air bags 2, and a point regulating valve is provided in the air outlet 201. The inflatable air bags 2 are connected to the exhaust pipe 301. 1 connection; elastic rope 202, fixedly connected to the expansion end of the inflatable airbag 2, when the elastic rope 202 is located in the cavity, it is in a stretched and taut state, when the elastic rope 202 extends from the cavity along with the inflatable airbag 2, it will drive the telescopic end of the inflatable airbag 2 to shrink inwardly toward the center of the circle; when the gas in the exhaust pipe 301 enters the inflatable airbag 2, the gas will be ejected from the air outlet 201 of the inflatable airbag 2 and converge above the hanging basket 1, forming an airflow curtain that converges at the top. When the electronic control in the air outlet 201 is turned on, the air will be discharged from the outlet 201 of the inflatable airbag 2. When the throttle valve reduces the air output, the inflatable airbag 2 expands accordingly, and the top of the inflatable airbag 2 extends out of the cavity. Under the action of the elastic rope 202, the inflatable airbag 2 can eventually cover the top of the hanging basket 1, and the inflatable airbag 2 will discharge the gas through the air outlet 201. The gas ejected from the numerous air outlets 201 will converge at the top of the hanging basket 1, forming an air flow curtain that converges at the top; the mounting rod 4 is fixedly connected to the hanging basket 1; the semi-ring 1 401 is fixedly connected to the mounting rod 4, and the semi-ring 1 401 is rotatably connected to the semi-ring 1 Ring 2 402, half ring 1 401 and half ring 2 402 can be assembled into a complete circular ring; a motor 403 is fixedly connected to half ring 1 401, and the output end of motor 403 is fixedly connected to half ring 2 402; multiple groups of clamping airbags 405 are respectively installed in half ring 1 401 and half ring 2 402, and the clamping airbags 405 are connected to the exhaust pipe 301; multiple groups of wear sensors 404 are respectively fixedly connected to half ring 1 401 and half ring 2 402, and the wear sensors 404 are used to detect the cable surface in the circular ring.
[0039] The inflatable airbag 2 in this device is an inflatable expansion airbag, and the inflation direction is the top. After inflation, it will stretch upwards. The initial state is as follows Figure 3 As shown, in the cavity located on the side wall of the hanging basket, as the exhaust pipe 301 continuously injects gas, if the electronic regulating valve is opened, the gas will be discharged through the air outlet 201, the inflatable airbag 2 cannot be expanded, and the gas will be ejected through the air outlet 201. The air outlet 201 is tilted. When the gas is discharged, it will be gathered into a conical airflow curtain through the tilted air outlet 201, and finally gathered at the top of the hanging basket 1. Subsequently, by closing the air outlet volume of the regulating valve, the inflatable airbag 2 can be expanded and extended upward from the cavity. Then, under the action of the elastic rope 202, it quickly converges to the center of the hanging basket, and then presents a conical shape, which is used for emergency use.
[0040] When the device is used, the crane is moved to the chemical plant, and the height of the hanging basket 1 is between 1.4 and 1.6 meters. Then the staff enters the hanging basket 1 by climbing over, and the air pump 3 works to suck in the cleaner air on the ground, and opens the electronic regulating valve of the air outlet 201 to discharge the gas. At this time, the ejected gas forms a conical wind curtain, that is, the wind curtain converges at the top to block the entry of external gas. Then the crane can be started to lift the hanging basket 1 to a high altitude until the semi-ring 401 is close to the cable in the cable bridge. At this time, the staff uses auxiliary tools to pick up the cable and make the cable fall into the semi-ring 401. Specifically, the installation rod 4 can be replaced with The telescopic rod or robotic arm facilitates the contact between half ring 1 401 and the cable, and the detection position can be adjusted at the same time. Then, the motor 403 can be used to make half ring 2 402 clamped on half ring 1 401 to fix the cable. At the same time, the gas discharged by the air pump 3 will enter the clamping airbag 405. At this time, the clamping airbag 405 will fix the cable and make the cable as coaxial as possible with half ring 1 401 and half ring 2 402. Then, the surface of the cable can be inspected by the wear sensor 404 to detect whether there is any damage on the cable surface. Other tools, such as temperature sensors, can also be used to detect whether the surface temperature of the cable is normal, whether there is abnormal heating, etc.
[0041] If an accident occurs later, such as the leakage of flammable, explosive or toxic gases from the surrounding chemical equipment, resulting in a large amount of gas pollution near the cable bridge, the gas output of the electronic regulating valve in the gas outlet 201 will be reduced, and the inflatable airbag 2 will expand rapidly, and under the action of the elastic rope 202, it will reach Figure 7 The state of the inflatable airbag 2 blocks the top of the hanging basket 1, similar to the state of wrapping. Affected by the shape of the inflatable airbag 2, even if the inflatable airbag 2 is soft and has the ability to deform, there will still be a certain gap at the top. At this time, the gas in the air outlet 201 is continuously discharged, which plays a role of gas sealing and prevents the entry of external gas. At the same time, the crane quickly lowers the hanging basket 1, and when the staff is close to the ground, the air pump 3 is turned off, and the inflatable airbag 2 gradually discharges the gas and shrinks, making it easy for the staff to leave the hanging basket 1 away from the dangerous area.
[0042] Due to the shape of the inflatable airbag 2, after use, it may be necessary to manually tidy up the inflatable airbag 2 and stuff the elastic rope 202 and the inflatable airbag 2 back into the cavity for the next use.
[0043] Example 2:
[0044] Reference Figure 9 、 Figure 10, a safety protection device for chemical electrical construction, which is basically the same as Example 1, further comprising: a vertical pole 5 is fixedly connected to the hanging basket 1, and a fan blade 6 is rotatably connected to the vertical pole 5. The fan blade 6 is located at the top of the conical airflow curtain and guides the airflow to the surroundings by rotation. A slide groove 501 is provided on the vertical pole 5, and a sliding ring 502 is slidably connected in the slide groove 501, and the fan blade 6 is rotatably connected to the sliding ring 502.
[0045] After the fan blades 6 are set in the hanging basket 1, and the position of the fan blades 6 is installed in the inflatable airbag 2 when it is initially fully expanded and not fully expanded, the gas discharged from the air outlet 201 will cause the fan blades 6 to continuously rotate on the vertical pole 5, and then guide the small end of the conical airflow to the lateral area or the inclined upward area, further promoting the flow of the surrounding gas. If there are some residual harmful gases near the cable bridge, these gases can be dissipated quickly to reduce the content of harmful gases in the air.
[0046] Example 3:
[0047] Reference Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 , a safety protection device for chemical electrical construction, which is basically the same as Example 2, further comprising: a piston cylinder 7 is fixedly connected to the vertical pole 5, a connecting plate is fixedly connected to the sliding ring 502, the telescopic end of the piston cylinder 7 is against the connecting plate, and the air inlet end and the air outlet end of the piston cylinder 7 are respectively connected to an air inlet pipe 701 and an air outlet pipe 702, and a one-way valve is connected to the air inlet pipe 701 and the air outlet pipe 702. The air inlet pipe 701 and the air outlet pipe 702 are used to guide the gas outside the hanging basket 1 into the hanging basket 1, and a filter box 8 is fixedly connected to the bottom of the hanging basket 1, a filter element 801 is connected to the filter box 8, and the air inlet pipe 701 is connected to the air outlet end of the filter box 8.
[0048] When the fan blades 6 are set to a state where they cannot move up and down, if the fan blades 6 are located at the top converging end of the conical airflow, the fan blades 6 will continue to rise under the action of the wind, and then squeeze the piston cylinder 7, so that the piston cylinder 7 will suck the gas at the bottom of the hanging basket 1 into the filter box 8, and the gas will be filtered through the filter element 801 inside the filter box 8. Subsequently, as the fan blades 6 move upward, they will leave the converging end of the conical airflow, and then fall back to the converging end below under the action of their own gravity, thus realizing the reciprocating movement of the piston cylinder 7, continuously sucking in the external gas, and after the filtration is completed, entering the hanging basket 1, which is convenient for the breathing of the staff in the hanging basket 1.
[0049] The up and down movement speed of the fan blade 6 can also be controlled by adjusting the air output of the electronic regulating valve, thereby adjusting the air output of the piston cylinder 7.
[0050] In case of emergency, when the hanging basket 1 needs to be protected by the inflatable airbag 2, the distance between the air outlets 201 is close, and the discharged gas will produce greater turbulence, which will continuously impact the fan blades 6, preventing it from falling. At this time, it is necessary to quickly move the staff from the high altitude to the ground.
[0051] Example 4:
[0052] Reference Figure 1-11 A safety protection device for chemical electrical construction is basically the same as Example 3, and furthermore: a mounting ring 9 is fixedly connected to the bottom of the hanging basket 1, and a plurality of air jets 901 are provided on the mounting ring 9. The air jets 901 are connected to the exhaust pipe 301. A connector 302 is connected to the hanging basket 1, and an outlet auxiliary pipe 303 is connected to the connector 302. The outlet auxiliary pipe 303 is connected to the inflatable airbag 2, and the outlet auxiliary pipe 303 is connected to the outlet auxiliary pipe 2. 4. The second outlet auxiliary pipe 304 is connected to the air jet port 901, the inflatable airbag 2 is connected to the third outlet auxiliary pipe 305, the third outlet auxiliary pipe 305 is connected to the clamping airbag 405, the clamping airbag 405 is connected to the hose 306 connected to the third outlet auxiliary pipe 305, the hanging basket 1 is connected to the second connector 803, the second connector 803 is connected to the connecting pipe 802, the connecting pipe 802 is connected to the air outlet end of the filter box 8, and the second connector 803 is connected to the air inlet pipe 701.
[0053] By setting the jet port 901, when in use, the air flow at the bottom can also flow through the jet port 901, promoting the rapid flow of the bottom gas, so that the filter box 8 can ensure continuous filtration of fresh gas.
[0054] The present invention inflates the inflatable airbag 2 through the air pump 3, so that the gas ejected therefrom forms a conical airflow curtain, thereby blocking the inside and outside of the hanging basket 1, reducing the entry of external gas, and preventing external gas from causing physical discomfort to the staff. At the same time, the gas generated by the air pump 3 will expand the clamping airbag 405, thereby clamping and wrapping the cable to be tested, so that a certain distance is maintained between it and the wear sensor 404, thereby improving the accuracy of subsequent cable detection by the wear sensor 404.
