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 , Fig.10 , Fig.11 A safety protection device for chemical electrical construction, comprising a hanging basket 1 installed on a crane, a cavity is arranged on the side plate of the hanging basket 1, the hanging basket 1 is a cylindrical body with the bottom and the sides sealed, and also comprising: an air pump 3, fixedly connected to the crane, an exhaust pipe 301 is connected to the air outlet end of the air pump 3; multiple groups of inflatable airbags 2, annularly fixedly connected to the cavity of the hanging basket 1, multiple groups of air outlets 201 are arranged on the inflatable airbags 2, and a point regulating valve is arranged in the air outlet 201, the inflatable airbags 2 and the exhaust pipe 30 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 out of the cavity along with the inflatable airbag 2, it will drive the telescopic end of the inflatable airbag 2 to shrink 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, and when the electronic regulator in the air outlet 201 When the throttle valve reduces the gas output, the inflatable airbag 2 expands accordingly, and the top of the inflatable airbag 2 will extend 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 gas outlet 201. The gas ejected from the plurality of gas outlets 201 will converge at the top of the hanging basket 1, forming an airflow curtain converging 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 an output end of the motor 403 is fixedly connected to half ring 2 402; a plurality of 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; a plurality of 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 the device is an inflatable expansion airbag, and the inflation direction is the top end. After inflation, it will stretch upward. 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, and the inflatable airbag 2 cannot be expanded, and the gas will be ejected through the air outlet 201. The air outlet 201 is inclined. When the gas is discharged, it will be gathered into a conical airflow curtain through the inclined air outlet 201, and finally gathered at the top of the hanging basket 1. Subsequently, by closing the gas outlet of the regulating valve, the inflatable airbag 2 can be expanded and extended upward from the cavity, and 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 meters 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, which blocks 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 by The telescopic rod or mechanical arm facilitates the contact between the half ring 401 and the cable, and the detection position can be adjusted at the same time. Then, the motor 403 can be used to make the half ring 402 clamp on the half ring 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 the half ring 401 and the half ring 402. Then, the surface of the cable can be detected 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 unexpected situation 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, the gas will be discharged. Figure 7 The top of the hanging basket 1 is blocked, similar to a wrapped state. Affected by the shape of the inflatable airbag 2, even if the inflatable airbag 2 is soft and has the ability to deform, there is still a certain gap at the top. At this time, the gas in the air outlet 201 is continuously discharged, which plays a role in 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 gas and shrinks, so that the staff can 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] Embodiment 2:

[0044] Reference Fig. 9 , Fig.10A safety protection device for chemical electrical construction is basically the same as Example 1, and further: a vertical pole 5 is fixedly connected in 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 fan blades 6 are 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, thereby guiding the small end of the conical airflow to the lateral area or the inclined upward area, further promoting the flow of 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] Embodiment 3:

[0047] Reference Figure 6 , Figure 7 , Fig. 9 , Fig.10 , a safety protection device for chemical electrical construction, which is basically the same as Example 2, and further: a piston cylinder 7 is fixedly connected to the vertical rod 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 with an air inlet pipe 701 and an air outlet pipe 702, and both the air inlet pipe 701 and the air outlet pipe 702 are connected with a one-way valve, 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, 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 sucks the gas at the bottom of the hanging basket 1 into the filter box 8, and the gas is 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 filtering 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 moving 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 exhaust gas will produce greater turbulence due to the close distance between the air outlets 201, and will continue to 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] Embodiment 4:

[0052] Reference Figure 1-11 A safety protection device for chemical electrical construction is basically the same as Example 3, and further: a mounting ring 9 is fixedly connected to the bottom of the hanging basket 1, and a plurality of groups of jet ports 901 are arranged on the mounting ring 9, and the jet ports 901 are connected to the exhaust pipe 301, and a connector 302 is connected to the hanging basket 1, and an exhaust pipe 303 is connected to the connector 302, and the exhaust pipe 303 is connected to the inflatable airbag 2, and the exhaust pipe 303 is connected to the exhaust pipe 2. 4. The second air outlet sub-pipe 304 is connected to the air jet port 901, the inflatable airbag 2 is connected to the third air outlet sub-pipe 305, the third air outlet sub-pipe 305 is connected to the clamping airbag 405, the clamping airbag 405 is connected to the hose 306 connected to the third air outlet sub-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 airflow 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 filtering of fresh gas.

[0054] The present invention inflates the inflatable airbag 2 through the air pump 3, so that the gas ejected forms a conical airflow curtain, thereby blocking the inside and outside of the hanging basket 1, reducing the entry of external gas, and preventing the 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, and then clamp and wrap the cable to be tested, so that a certain distance is maintained between it and the wear sensor 404, so as to improve the accuracy of subsequent wear sensor 404 in detecting the cable.
