It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those shown or described.

[0031] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Some embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] In order to solve the problems existing in the prior art, the embodiment of the utility model provides a hot work protection device for preventing the triggering of a fire detection alarm, comprising:

[0034] Support frame, protective cover and air cleaning mechanism;

[0035] The protective cover is arranged on the supporting frame to form a closed space for isolating the hot work area;

[0036] The protective cover is provided with an air inlet and an air outlet;

[0037] The air purification mechanism is connected to the air inlet through a conduit.

[0038] It is understandable that the enclosed space formed by the protective cover and the support frame can isolate the arc light generated in the hot work area during hot work operations to avoid triggering fire alarms.

[0039] It can be understood that when purifying the air in the sealed space, the air purification mechanism extracts turbid air such as smoke in the sealed space. As the gas in the closed space is extracted, the air pressure decreases, allowing fresh air from the outside to enter the closed space through the second through hole.

[0040] For example, see Figure 1 , showing a schematic structural diagram of a hot work protection device for preventing the triggering of a fire detection alarm.

[0041] like Figure 1 As shown, the device includes a protective cover 1 and a supporting frame 2. The protective cover 1 is fitted on the supporting frame 2 to form a closed space that isolates the fire area. The air purification mechanism 2 is connected to the first through hole 4 set on the side of the protective cover 1 through a conduit 6 and is connected to the closed space, so that the air purification mechanism 3 can purify the air by extracting turbid air such as smoke in the closed space. The top surface of the protective cover 1 is provided with a second through hole 5, and the second through hole 5 is provided with a pipe with a bending curvature. Fresh air from the outside enters the closed space through the pipe with a bending curvature and the second through hole 5 in turn.

[0042] It is understandable that the curved pipe can prevent external debris from clogging the second through hole 5 .

[0043] In some feasible embodiments, based on the above solution, the support frame includes a plurality of connecting rods and a plurality of connecting parts;

[0044] The plurality of connecting rods and the plurality of connecting parts are assembled to form the supporting frame.

[0045] For example, see Figure 2 , showing a structural schematic diagram of a support frame.

[0046] The support frame 2 includes eight connecting parts 21 and twelve connecting rods 22, wherein one connecting part 21 is connected to three connecting rods 22, and both ends of a connecting rod 22 are respectively connected to a connecting part 21. The eight connecting parts 21 and the twelve connecting rods 22 are finally assembled to form the support frame 2.

[0047] It is understandable that, since the support frame constructed in the embodiment of the utility model is a rectangular structure, the above-mentioned assembly method is adopted. If the support frame adopts other structures, such as a hemispherical structure, a different assembly method is adopted.

[0048] In some feasible embodiments, based on the above-mentioned solution, the connecting portion is provided with three plugging holes for plugging the connecting rod, and the axes of any two of the plugging holes are orthogonal to each other.

[0049] For example, see Figure 3 , showing a schematic diagram of the connection between the connecting part and the connecting rod.

[0050] like Figure 3 As shown, the overall structure of the connecting portion 21 is similar to a three-way joint, including three plug holes, one plug hole is plugged with a connecting rod 22, and the three plug holes are perpendicular to each other.

[0051] It is understandable that, in addition to being connected and fixed to the insertion hole by plugging, the connecting rod can also be connected by threading. When threading is used, the insertion hole and the connecting rod are respectively provided with external threads and internal threads.

[0052] In some feasible embodiments, based on the above-mentioned solution, the support frame is a rectangular structure.

[0053] It can be understood that, since the support frame is composed of connecting parts and connecting rods, and the rectangular body structure is easier to assemble and saves assembly time, the support frame of the rectangular body structure is adopted in the utility model.

[0054] In some feasible embodiments, based on the above solution, the protective cover includes a first protective portion, a second protective portion, a third protective portion, a fourth protective portion and a fifth protective portion;

[0055] The first protection part, the second protection part, the third protection part, the fourth protection part and the fifth protection part are connected by a zipper structure to form a whole.

[0056] It is understandable that multiple independent protection parts can be assembled on site when it is necessary to isolate the fire area, and they can be connected and assembled with each other using a zipper structure, and the assembly method is simple and convenient.

[0057] For example, see Figure 4 , showing a schematic structural diagram of a protective cover.

[0058] The protective cover 1 includes a first protective part 11, a second protective part 12, a third protective part 13, a fourth protective part 14 and a fifth protective part 15. In order to cooperate with the supporting frame of the rectangular structure, in the utility model, each protective part is configured to be rectangular, and each protective part is connected by a zipper structure. After assembly, a rectangular box body is formed.

[0059] In some feasible embodiments, based on the above solution, the first through hole and the second through hole are arranged on different protective parts.

[0060] For example, Figure 4 As shown, the first through hole 3 is arranged on the second protective part 12, and the second through hole 4 is arranged on the fourth protective part 14. After the protective parts are assembled, the second protective part 12 is the side surface of the rectangular box body, and the fourth protective part 14 is the top surface of the rectangular box body.

[0061] In some feasible embodiments, based on the above-mentioned solution, a mounting plate for fixing the lighting fixture is provided on the top of the supporting frame.

[0062] For example, see Figure 5 , showing a schematic diagram of fixing the mounting plate.

[0063] like Figure 5 As shown, the head of the hanging hook 8 is provided with a bending portion, through which the hanging hook 8 is suspended on the connecting rod at the top of the supporting frame. At the same time, a hook is also provided in the middle of the hanging hook 8, and a hanging hole is provided on the mounting plate 7, and the mounting plate 7 is hung on the hanging hook 8 through the hanging hole.

[0064] Below, a protective operation process of this protective device is provided.

[0065] Before the hot work begins, assemble the connection parts and connecting rods, as well as multiple protective parts on site, and place the hot work point close to the side hole of the protective cover. Since the protective cover has the function of blocking light, fix the lighting fixtures on the internal mounting plate in advance. Then connect the air purification mechanism and guide pipe in turn, and you can start the operation. During the operation, turn on the air purification mechanism, and the smoke generated by the hot work point will be guided out of the protective cover through the air purification mechanism, and fresh air will also be replenished into the protective cover through the second through hole.

[0066] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the embodiments disclosed herein. The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention. It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
