Description

Technical Field

[0001] This utility model belongs to the technical field of water curtain spraying facilities, and more specifically, it relates to a water curtain spraying device for eliminating high-altitude sparks. Background Technology

[0002] During cutting or welding operations at height, a large number of sparks are generated. These sparks falling downwards pose a significant safety hazard, potentially leading to fires or even explosions. Therefore, it is necessary to appoint a safety officer to monitor and manage the sparks generated during operations and to install protective devices to prevent the danger caused by falling sparks.

[0003] In traditional high-altitude welding operations, a slag catcher is usually placed below to prevent welding slag from falling and causing danger. However, if the uncooled welding slag hits the bottom of the catcher, it will cause splattering. If it splashes onto flammable materials, it can easily cause a fire, resulting in unnecessary property damage and safety hazards.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a water curtain spray device to eliminate high-altitude sparks, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a water curtain spray device for eliminating high-altitude sparks, which is achieved by the following specific technical means:

[0006] A water curtain spray device for eliminating high-altitude sparks includes a trolley and a fire-receiving hopper. A water storage tank is installed on the upper surface of the trolley, and a water outlet pipe is installed on one side of the water storage tank. The other end of the water outlet pipe is connected to a water pump, and a water delivery pipe is connected to one side of the water pump. A water inlet pipe is connected to the upper surface of the water storage tank. Several connecting rods are installed inside the fire-receiving hopper, and the other ends of the connecting rods are connected to water curtain spray pipes. Several spray heads are installed on both sides of the water curtain spray pipes, and a water inlet connector is installed on one side of the water curtain spray pipes. An installation groove is provided on one side of the fire-receiving hopper below the water curtain spray pipes, and a fixing mechanism is installed on one side of the fire-receiving hopper above the installation groove. A water outlet connector is installed at the bottom of the fire-receiving hopper. The device also includes a filter screen, the size of which matches the size of the installation groove.

[0007] Furthermore, a pair of hooks are installed on both sides of the upper end face of the fire-receiving hopper.

[0008] Furthermore, the fixing mechanism includes a support block, a pull rod, a compression spring, a mounting block, and a pair of locking blocks. The support block is installed on one side of the fire-receiving hopper. The pull rod is movably connected to the upper end face of the support block. The bottom end of the pull rod passes through the bottom end face of the support block and connects to the mounting block. The pair of locking blocks are installed on both sides of the bottom end face of the mounting block. The compression spring is fitted around the pull rod.

[0009] Furthermore, a pair of limiting rods are installed on both sides of the upper end face of the mounting block, and the top ends of the pair of limiting rods pass through the support block and are movably connected to the support block.

[0010] Furthermore, a handle is installed on one side of the filter screen, and a pair of support blocks are installed on both sides of the handle. The upper surface of the support blocks is provided with a slot, and the size of the block matches the size of the slot.

[0011] Furthermore, the water inlet connector is connected to the water supply pipe via a flange.

[0012] Furthermore, the outlet connector is connected to the inlet pipe via a flange.

[0013] Furthermore, a controller is installed on the upper surface of the trolley.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By using the water outlet pipe, water pump, water supply pipe, water inlet connector, water curtain spray pipe and spray head in combination, when workers are performing high-altitude welding operations, the water pump is started. The water pump draws water from the water storage tank through the water outlet pipe and delivers it to the water curtain spray pipe through the water supply pipe and water inlet pipe. Then it is sprayed out through the spray head. When the welding slag falls into the fire-catching hopper, the high-temperature welding slag will be quickly cooled by the water sprayed from the water curtain spray pipe, which can effectively prevent the welding slag from splashing onto flammable materials and causing fire, resulting in unnecessary property damage and safety hazards.

[0016] By using a filter screen, water outlet connector, and water inlet pipe in combination, the cooled water falls onto the filter screen, which filters out the welding slag. The filtered water then returns to the water storage tank through the water outlet connector and water inlet pipe, allowing water resources to be reused and thus improving the environmental protection effect of the device.

[0017] By using a pull rod, compression spring, mounting block, locking blocks, and locking slots in combination, when a large amount of welding slag accumulates on the surface of the filter screen, the operator moves the pull rod upward. The pull rod, through the mounting block, drives a pair of locking blocks upward and disengages from the locking slot. Then, the filter screen is removed using the handle. After the welding slag is cleaned, the filter screen is installed into the mounting slot. At this point, the pull rod is released, and under the force of the compression spring, the compression spring pushes the mounting block downward. The mounting block pushes a pair of locking blocks into the locking slot, fixing the filter screen in place. This achieves the effect of quickly cleaning welding slag. Attached Figure Description

[0032] The fixing mechanism 6 includes a support block 601, a pull rod 602, a compression spring 603, a mounting block 604, and a pair of locking blocks 605. The support block 601 is installed on one side of the fire-receiving hopper 2. The pull rod 602 is movably connected to the upper end face of the support block 601. The bottom end of the pull rod 602 passes through the bottom end face of the support block 601 and is connected to the mounting block 604. A pair of locking blocks 605 are installed on both sides of the bottom end face of the mounting block 604. The compression spring 603 is fitted around the pull rod 602.

[0034] Among them, a handle 701 is installed on one side of the filter screen 7, and a pair of support blocks 702 are installed on both sides of the handle 701.

[0038] The working principle of this embodiment:

[0039] Workers hang the welding hopper 2 below the welding position using hook 204. When workers are performing high-altitude welding, they start the water pump 4. The pump 4 draws water from the storage tank 3 through the outlet pipe 301 and delivers it to the water curtain spray pipe 5 through the supply pipe 401 and inlet pipe 302. The water is then sprayed out through the spray head 501. When welding slag falls into the welding hopper 2, the high-temperature slag is rapidly cooled by the water sprayed from the water curtain spray pipe 5, effectively preventing slag from splashing onto flammable materials and causing a fire. The cooled water falls onto the filter screen 7, which filters the welding slag. The filtered water then returns to the storage tank 3 through the outlet connector 203 and inlet pipe 302. Inside the water tank 3, water resources can be reused. When a lot of welding slag accumulates on the surface of the filter screen 7, the operator moves the pull rod 602 upward. The pull rod 602 drives a pair of locking blocks 605 upward through the mounting block 604 and disengages them from the slot 703. Then, the filter screen 7 is removed through the handle 701. After the welding slag is cleaned, the filter screen 7 is installed into the mounting slot 202. At this time, the pull rod 602 is released. Under the force of the compression spring 603, the compression spring 603 pushes the mounting block 604 downward. The mounting block 604 pushes a pair of locking blocks 605 into the slot 703, fixing the filter screen 7, thereby achieving the effect of quickly cleaning welding slag.
