Description

Technical Field

[0001] The invention relates to the technical field of welding protection, and in particular to a hot work site protection device. Background Art

[0002] There are a lot of welding operations in the process of ship construction. Sparks and thick smoke will appear during the welding process, affecting the surrounding environment. In the welding process, there are often other processes, such as equipment installation by fitters, grinding by grinders, wiring by electricians, correction by pyrotechnicians, and pipeline installation by plumbers. Sparks in the welding process cannot be controlled and will splash around, affecting the normal operation of other types of work. Especially when some cabins, equipment and pipelines in the engine room of the ship are filled with oil, there are strict requirements for the surrounding welding working environment to avoid fire hazards caused by sparks. Therefore, during the welding operation, attention must be paid to the prevention of sparks.

[0003] A Chinese utility model patent with an authorization announcement date of February 8, 2022 and an authorization announcement number of CN215747327U discloses a mobile welded folding protective door, which includes a main door panel and a secondary door panel arranged in sequence, and the main door panel and the secondary door panel are hingedly connected together by hinges. A running wheel is also provided at the bottom of the main door panel, and a supporting structure is also provided at the bottom of the secondary door panel. The protective door can be conveniently moved to a specific area to be protected by the running wheels. The main door panel and the secondary door panel have the same structure, both including an internal reinforcement plate and a fireproof plate located outside the reinforcement plate, and an aluminum alloy plate is also provided outside the fireproof plate to protect and shield sparks. The running wheel is provided with a brake, and the supporting mechanism includes a suction cup for adsorbing on the ground, so that it can be more stably supported on the ground during use.

[0004] In the above technical solution, the support mechanism supports the side wall or the welding position with a certain height on the ground, and can separate the welding point and the protected area in the horizontal direction. However, the main door panel and the auxiliary door panel are both vertically arranged composite panels. If the welding point and the protected area are arranged with intervals, the above protective door cannot be used. In addition, during the welding process, there are some horizontally arranged pipes, and these pipes transport oil. For the protection of such pipes, the horizontally arranged protective door can only be arranged vertically and at intervals with the pipes, and there is a risk of Mars falling from the top. Summary of the invention

[0005] In view of this, the present invention provides a fire scene protection device to solve the problem that the protection device in the prior art can only provide protection on the sides but lacks the ability to protect against sparks falling from heights.

[0006] A fire scene protection device includes at least one group of horizontally arranged protection components, each group of protection components is provided with a base at the bottom, each group of protection components includes two fire protection panels hingedly connected to each other, the two fire protection panels in each group of protection components are hingedly connected to each other at one end with a connecting piece, and a guide rod extending up and down is provided on the base. The connecting piece on at least one fire protection panel can be locked and slidably connected to the guide rod to form a movable connecting piece.

[0007] Furthermore, the movable connecting member is a connecting sleeve which is sleeved on the outer peripheral surface of the guide rod and can slide relative to the guide rod.

[0008] Furthermore, the connecting sleeve is provided with a threaded hole, in which a top screw is mounted for abutting against the outer peripheral surface of the guide rod to complete locking.

[0009] Furthermore, the connecting piece on one of the fireproof boards is a movable connecting piece, and the connecting piece on the other fireproof board is a fixed connecting piece fixedly arranged on the guide rod.

[0010] Furthermore, the fixed connection piece is arranged at an end of the guide rod away from the base.

[0011] Furthermore, the end of the fixed connection piece is flush with the end of the guide rod.

[0012] Furthermore, the base is a magnetic base so that the base can be adsorbed on a vertically arranged bottom surface.

[0013] Furthermore, a fireproof blanket or fireproof cloth is laid on the outer peripheral surface of the fireproof board.

[0014] Furthermore, the two fireproof panels in each set of protection components are equal in size.

[0015] Furthermore, at least two protective components are provided, and the protective components between adjacent groups are hingedly connected together, and the hinge axes of the upper and lower fireproof panels in different groups are at the same horizontal height.

[0016] The beneficial effects of the hot fire site protection device in the present invention are as follows: the hot fire site protection device in the present invention facilitates protection of welding positions or areas to be protected by providing protection components arranged in groups, and is convenient for placement by providing a base; by providing two fireproof panels hingedly connected up and down in each group of protection components, it is convenient to fold in the up and down directions; since a guide rod is provided on the base, the fireproof panel is provided on the guide rod through a connecting piece, so that when the position of the connecting piece relative to the guide rod changes, the upper and lower fireproof panels can be folded relative to each other, and the folded protection component has a V-shaped space, which can wrap up smaller parts to be protected or welding parts, thereby achieving better protection effect, thereby solving the problem that the protection device in the prior art can only provide protection on the side and lacks the ability to protect against sparks falling from heights.

[0033] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0034] In the embodiment 1 of the hot work site protection device (hereinafter referred to as the protection device) of the present invention:

[0035] like Figure 1As shown, the protective device in the present invention includes two groups of protective components, the two groups of protective components are horizontally arranged, and the two groups of protective components are hingedly connected by hinges. The two groups of protective components have the same structure, and a base 1 is provided at the bottom of each group of protective components, wherein the first group of protective components includes a first fireproof board 31 and a second fireproof board 32, and the second group of protective components includes a third fireproof board 33 and a fourth fireproof board 34. The structure is introduced by taking the first group of protective components as an example.

[0036] like Figure 1 and Figure 5 As shown, the first group of protection components includes fireproof panels hingedly connected up and down, and the fireproof panels are rectangular. The horizontal edges at the top of the first fireproof panel 31 and the horizontal edges at the bottom of the second fireproof panel 32 are hingedly connected by horizontal hinges 41, wherein the horizontal hinges only refer to multiple hinges extending in the horizontal direction. The first fireproof panel 31 and the second fireproof panel 32 can rotate relative to each other through the setting of the horizontal hinges 41, and a V-shaped space can be formed during the rotation process. The V-shaped space can shield the welding parts or the parts to be protected to avoid the risk of fire, and the protection effect is better. The two groups of protection components are hingedly connected together by the longitudinal hinges 42, and the hinge axes of the upper and lower fireproof panels in different groups are at the same horizontal height, so as to facilitate the synchronous folding of the fireproof panels in the two groups of protection components.

[0037] like Figure 1 and Figure 2As shown, in order to effectively limit the positions of the two fireproof panels, a guide rod 2 is also provided. The guide rod 2 is a cylindrical metal rod, and the guide rod 2 is fixedly arranged on the base 1. The base 1 is used to be fixed at the position to be placed, and the guide rod 2 is fixed together with the base 1, that is, the guide rod 2 also forms a relatively fixed foundation. The first fireproof panel 31 is located at the bottom, and the second fireproof panel 32 is located at the top. A first connecting member is hingedly connected to the bottom of the first fireproof panel 31, and a second connecting member is hingedly connected to the top of the second fireproof panel 32, that is, the first connecting member and the second connecting member are located at the ends of the two fireproof panels in each group that are away from each other. Specifically, the connecting member is a connecting sleeve mounted on the guide rod 2. The first connecting sleeve on the first fireproof panel 31 can be movably arranged on the guide rod 2, forming a movable connecting sleeve 51, and the second connecting sleeve on the second fireproof panel 32 is fixedly arranged on the guide rod 2 and cannot move relative to the guide rod 2, forming a fixed connecting sleeve 52. In order to achieve the limit at any position, a threaded hole is provided on the outer circumference of the first connecting sleeve, and a top screw is installed in the threaded hole for pressing against the outer circumference of the guide rod 2 to complete the mutual locking of the first connecting sleeve and the guide rod 2. Normally, loosening the top screw can achieve the adjustment of the first connecting sleeve, and tightening the top screw can achieve the mutual locking of the first connecting sleeve and the guide rod 2. The first connecting sleeve is moved and the second connecting sleeve is locked, so that the positions of the two fireproof panels can be adjusted, and at the same time, it can also avoid damage caused by the connecting sleeve coming off the guide rod 2 during the movement and adjustment process.

[0038] Of course, in other embodiments, the top screw may not be provided, and the first connecting sleeve and the guide rod are interference fit, so there is friction damping between the first connecting sleeve and the guide, and the friction damping is used to make the connecting sleeve move only under the action of a large external force. When the external force is removed, the friction damping is used to achieve the relative fixation of the first connecting sleeve and the guide rod. Alternatively, in other embodiments, a dovetail groove is provided on the guide rod, and the first connecting member is a dovetail block, and the dovetail block is equipped with a top screw that abuts against the dovetail groove, thereby achieving the sliding and locking of the first connecting member and the guide rod. Of course, in other embodiments, both the first connecting sleeve and the second connecting sleeve can be set as movable connecting sleeves. When moving the second connecting sleeve, it should be noted that the second connecting sleeve should not fall off the guide rod during the movement. At this time, an anti-falling portion that prevents the connecting sleeve from falling off can be provided on the end of the guide rod away from the base.

[0039] In order to realize the connection between the first connecting sleeve and the second connecting sleeve and the guide rod 2 respectively, as shown in FIG. Figure 8As shown, the second fireproof plate 32 is fixedly provided with a second connection edge 321, and the second connection sleeve is a U-shaped connection sleeve, and the groove bottom of the U-shaped connection sleeve is used to prevent the guide rod 2 and is welded to the guide rod 2. Bolt mounting holes are provided on the side wall of the U-shaped connection sleeve, and another through hole corresponding to the bolt mounting hole is provided on the second connection edge 321 of the second fireproof plate 32, and then after the bolts are inserted, the second connection edge 321 of the second fireproof plate 32 forms a hinged connection relationship with the second connection sleeve. Accordingly, as shown in FIG. Figure 6 and Figure 7 As shown, a first connecting edge 311 is fixedly provided on the first fireproof plate 31, a U-shaped groove is provided on the first connecting sleeve, a sleeve hole for sleeve-mounting the guide rod 2 is further provided at the end away from the U-shaped groove, a top screw (not shown in the figure) is further provided on the outer peripheral surface of the sleeve hole, a bolt mounting hole is provided on the groove side wall of the U-shaped groove, another through hole corresponding to the bolt mounting hole is provided on the first connecting plate of the first fireproof plate 31, and a hinged connection between the first fireproof plate 31 and the first connecting sleeve is realized by inserting bolts.

[0040] like Figure 1 As shown, for a more stable movement, two guide rods 2 are provided in each group, and the two guide rods 2 are arranged vertically and parallelly at intervals. In order to make the most effective use of the guide rods 2, the end of the second connecting sleeve is flush with the end of the guide rod 2 away from the base 1, so that the guide rod 2 can be used to the greatest extent. Of course, in other embodiments, the second connecting sleeve may no longer be flush with the end of the guide rod, and the guide rod may extend longer.

[0041] During the welding process, there may be a situation where the welding position and the component to be protected are arranged in an upper and lower interval. In this embodiment, the base 1 is a magnetic base, which can be adsorbed on the vertically arranged bulkhead 7. Figure 3 As shown, after the base 1 is adsorbed on the bulkhead 7, the first fireproof board 31 and the second fireproof board 32 are arranged horizontally. Of course, in other embodiments, the base 1 can also be set as an ordinary steel base 1, in which case the base 1 can only be placed on a horizontal surface.

[0042] In order to further enhance the protection effect against sparks, the fireproof board is a steel plate, specifically a 3-5 mm steel plate. The use of such a steel plate can not only achieve fire prevention, but also provide protection when there are falling objects from high altitude during welding operations. In addition, a fireproof blanket 6 is also laid on the outer surface of the fireproof board to further enhance the effect of preventing sparks. Of course, in other embodiments, the fireproof blanket can also be replaced with a fireproof cloth. Alternatively, in other embodiments, the fireproof board can also be replaced with a thin iron sheet, which no longer has the function of preventing falling objects from high altitude.

[0043] In the embodiment 2 of the hot work site protection device (hereinafter referred to as the protection device) of the present invention:

[0044] When welding, not only sparks are generated, but also thick smoke is generated. When there is too much thick smoke, it not only affects the environment, but also has an adverse effect on the health of the operator. In this embodiment, the size of the fireproof board is changed so that the size of the first fireproof board 31 and the second fireproof board 32 in each group are no longer the same. Figure 4 As shown, at this time, the size of the first fireproof board 31 along the guide rod 2 is smaller than the size of the second fireproof board 32. When playing a protective role, ventilation holes for air circulation can be formed, thereby facilitating the dissipation of thick smoke.

[0045] It should be clear that the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.
