Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , as shown in the figure, a leak plugging device for a dangerous chemical tank body opening includes a plugging structure 1. The plugging structure 1 includes a plugging airbag 101 for plugging the opening of the dangerous chemical tank body. A hard conduit 102 communicating with it is fixedly installed at the center of the rear end of the plugging airbag 101; an anti-splash structure 2 for preventing liquid spraying during the plugging process is installed outside the hard conduit 102. The anti-splash structure 2 includes a hollow tube 201 for guiding the liquid flow. A support assembly 3 for supporting the plugging structure 1 is installed between the hard conduit 102 and the hollow tube 201.

[0028] Please refer to Figure 5 , a gasket 202 is fixedly sleeved on the outside of the hollow tube 201 near the end close to the plugging airbag 101. The gasket 202 is made of rubber material, and the gasket 202 made of rubber material is convenient for fitting with the outer wall of the tank body.

[0029] Please refer to Figure 6 , a soft conduit 203 is installed at the end of the hollow tube 201 far from the plugging airbag 101. The soft conduit 203 can discharge the liquid in the hollow tube 201. A threaded seat 204 is fixedly sleeved on the outside of the hollow tube 201 near the end close to the soft conduit 203.

[0030] Please refer to Figure 6, one end of the flexible conduit 203 close to the hollow tube 201 is fixedly connected with a threaded sleeve 205, and an anti - detachment ring 206 is threadedly installed on the outer side of the threaded seat 204. The anti - detachment ring 206 can prevent the threaded sleeve 205 from detaching from the flexible conduit 203.

[0031] The working principle of avoiding liquid spraying during leak stoppage: When there is a break in the hazardous chemical storage tank, causing the liquid stored inside to leak, the operator first applies a high - strength adhesive on the outer side of the gasket 202, and then covers the hollow tube 201 outside the break of the tank body. Press the gasket 202 to make it firmly adhered to the tank body. Since the gasket 202 is made of rubber material, the gasket 202 can adapt to the arc - shaped outer wall of the tank body. At this time, the leaked liquid in the tank body enters the liquid storage bucket through the hollow tube 201 and the flexible conduit 203, which can effectively avoid the liquid in the tank body splashing and endangering the operator during the process of plugging the leak of the tank body, and can also effectively prevent the leaked liquid from polluting the environment on a large scale.

[0032] Embodiment Two

[0033] Please refer to Figure 4 , in this embodiment, a further description is made for Embodiment One. The rigid conduit 102 penetrates through the side wall of the hollow tube 201. The upper end of the rigid conduit 102 is fixedly connected with a valve one 103. The valve one 103 is used to control the flow state of the rigid conduit 102. The valve one 103 is fixedly embedded on the outer side of the hollow tube 201. The upper end of the valve one 103 is installed with a detachable gas conduit 104, and the gas conduit 104 is made of a flexible hose.

[0034] Please refer to Figure 4 , the support assembly 3 includes a support seat 301 fixedly sleeved on the outer side of the rigid conduit 102, and the support seat 301 is fixedly connected with the hollow tube 201 through a plurality of connecting rods evenly distributed in a circumferential manner. The support seat 301 can support the rigid conduit 102. One end face of the support seat 301 close to the leak - plugging airbag 101 is fixedly embedded with a support tube 302, and the support tube 302 is fixedly sleeved on the outer side of the rigid conduit 102. The support tube 302 is convenient for inserting the leak - plugging airbag 101 into the break of the tank body.

[0035] Please refer to Figure 1 , one end of the gas conduit 104 away from the valve one 103 is fixedly connected with an air - inflating pump, and one end of the flexible conduit 203 away from the hollow tube 201 is communicated with the liquid storage bucket. The liquid storage bucket can collect the liquid leaked from the tank body.

[0036] In this embodiment: Before covering the broken opening of the tank body with the hollow tube 201, the operator first inserts the leak stoppage airbag 101 into the tank body through the hollow tube 201, and then bonds the gasket 202 to the tank body. After the gasket 202 is firmly bonded to the tank body, the operator controls the air pump to start running. The air pump inflates the leak stoppage airbag 101. The leak stoppage airbag 101 expands after being inflated inside the tank body and plugs the broken opening of the tank body from the inside of the tank body. Under the action of the liquid pressure, the leak stoppage airbag 101 closely fits the side wall of the broken opening of the tank body, which not only enables the leak stoppage structure 1 to have a good leak stoppage effect on the tank body, but also can plug broken openings of different shapes.

[0037] Embodiment Three

[0038] Please refer to Figure 1 , this embodiment further describes the second embodiment. A second valve 4 for controlling the flow state of the hollow tube 201 is further installed inside the hollow tube 201.
