Description

Technical Field

[0001] The utility model relates to the field of leakage treatment, in particular to a movable protective cover for an equipment leakage area. Background Technique

[0002] During the operation of hazardous chemical enterprises, toxic, harmful, flammable and explosive gas leakage is likely to occur at positions such as flanges, valves, instruments, drain cocks, mechanical seals, packings and pipelines in the plant, thus causing personnel poisoning, fire or explosion accidents.

[0003] After a pipeline leaks, an absorption hood will be set at the leakage part. The suction pipe on the absorption hood will extract the gas in the absorption hood, thus forming a negative pressure in the absorption hood to absorb the gas leaking from the pipeline. However, in actual use, some gas will escape from the edge of the absorption hood, which is likely to cause personnel poisoning. Therefore, a movable protective cover for an equipment leakage area is proposed. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a movable protective cover for an equipment leakage area, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A movable protective cover for an equipment leakage area includes a first protective cover and a second protective cover. Docking feet are provided at both ends of the first protective cover and the second protective cover.

The movable wheel is movably mounted on the first bracket and the second bracket respectively through the movable shaft, and the movable wheel drives the first protective cover and the second protective cover to move.

[0010] Furthermore, the sealing mechanism includes a first ring seat fixed at the edge of both ends of the first protective cover and a second ring seat fixed at the edge of both ends of the second protective cover. Positioning grooves are provided on both the first ring seat and the second ring seat. A sealed inflatable bag is fixedly installed in the positioning groove on the second ring seat. An inflatable pipe is connected to the sealed inflatable bag, and an air pump is provided at the end of the inflatable pipe.

Driving mechanisms 7 are provided at both ends of the first protective cover 1. Positioning slots 8 are provided at the edges of both ends of the first protective cover 1. The driving mechanism 7 includes a first bracket 701 and a second bracket 702 provided at the edges of both ends of the first protective cover 1. Movable wheels 704 are movably installed on both the first bracket 701 and the second bracket 702. A sealing mechanism 6 is provided at the edges of both ends of the first protective cover 1 and the second protective cover 2. During use, the first protective cover 1 and the second protective cover 2 can be sleeved on the pipeline. After the first protective cover 1 and the second protective cover 2 are sleeved on the pipeline, the docking bolts 5 can be tightened to connect the first protective cover 1 and the second protective cover 2 together.

[0023] As Figure 3As shown in the figure, the driving mechanism 7 includes a first bracket 701 and a second bracket 702 arranged at both ends of the first protective cover 1. Movable wheels 704 are movably installed on both the first bracket 701 and the second bracket 702. The driving mechanism 7 further includes a movable shaft 703 movably installed on the first bracket 701 and the second bracket 702. A driving motor 705 is fixedly installed on the second bracket 702. A driving shaft 706 is fixedly installed at the output end of the driving motor 705. A first helical gear 707 is fixedly installed on the driving shaft 706. A second helical gear 708 is fixedly installed on the movable shaft 703, and the first helical gear 707 meshes with the second helical gear 708.

[0024] Specifically, after the first protective cover 1 and the second protective cover 2 are connected together, the driving motor 705 can be started. After the driving motor 705 is started, the driving shaft 706 will drive the first helical gear 707 to rotate. After the first helical gear 707 rotates, it will drive the second helical gear 708 to rotate. After the second helical gear 708 rotates, it will drive the movable wheels 704 on the movable shaft 703 to rotate, so as to drive the first protective cover 1 and the second protective cover 2 to move to the pipeline leakage point. After the first protective cover 1 and the second protective cover 2 move to the pipeline leakage point, the leaked gas can be sucked through the suction pipe 9 to prevent personnel from being poisoned.

[0025] As Figure 4 shown in the figure, the sealing mechanism 6 includes a first ring seat 601 fixed at both ends of the first protective cover 1 and a second ring seat 602 fixed at both ends of the second protective cover 2. Positioning grooves 603 are formed on both the first ring seat 601 and the second ring seat 602.

An air pump 605 is arranged at the end of the inflatable pipe 607. A one-way valve 606 is arranged at the connection between the air pump 605 and the inflatable pipe 607.

[0026] The driving motor 705 will drive the movable wheels 704 to roll along the pipeline surface, so as to drive the first protective cover 1 and the second protective cover 2 to move. After the first protective cover 1 and the second protective cover 2 move to the pipeline leakage point, the air pump 605 can be started. After the air pump 605 is started, the external gas will be filled into the sealing inflatable bag 604 through the inflatable pipe 607, causing the sealing inflatable bag 604 to expand. After the sealing inflatable bag 604 expands, it will block the gap between the protective cover and the pipeline, thereby reducing gas escape when dealing with leaked gas.

[0027] It should be noted that the present utility model is a movable protective cover for the leakage area of a device. During actual use, the first protective cover 1 and the second protective cover 2 are sleeved on the pipeline. After the first protective cover 1 and the second protective cover 2 are sleeved on the pipeline, the docking bolts 5 can be tightened to connect the first protective cover 1 and the second protective cover 2 together. After the first protective cover 1 and the second protective cover 2 are connected together, the drive motor 705 can be started. Since the movable shaft 703 is respectively movably installed on the first bracket 701 and the second bracket 702 through bearings, and the movable wheels 704 are respectively movably installed on the first bracket 701 and the second bracket 702 through the movable shaft 703, and the first helical gear 707 is engaged with the second helical gear 708, after the drive motor 705 is started, the drive shaft 706 will drive the movable wheels 704 on the movable shaft 703 to rotate, so as to drive the first protective cover 1 and the second protective cover 2 to move to the pipeline leakage point. After the first protective cover 1 and the second protective cover 2 move to the pipeline leakage point, the air pump 605 can be started. Since one end of the air inflation pipeline 607 is connected to the sealed air inflation bag 604, the other end of the air inflation pipeline 607 is connected to the air pump 605, and the one-way valve 606 only allows external gas to enter the air inflation pipeline 607, after the air pump 605 is started, the external gas will be filled into the sealed air inflation bag 604 through the air inflation pipeline 607, causing the sealed air inflation bag 604 to expand. After the sealed air inflation bag 604 expands, it will block the gap between the protective cover and the pipeline. Then, the leaked gas can be sucked through the suction pipe 9 to prevent personnel from being poisoned.
