Description

Technical Field

[0001] This utility model relates to the field of hazardous waste storage protection technology, specifically a mobile liquid interception device for hazardous waste storage. Background Technology

[0002] Petrochemical storage facilities store Class A, B, and C liquids, such as gasoline, benzene, toluene, methanol, ethanol, acetone, kerosene, diesel, and heavy oil, typically in drums stored inside warehouses. In the event of a fire in such a warehouse, especially if the aforementioned drummed liquids explode, they can easily spill onto the warehouse floor. Therefore, facilities must be installed at the entrance to prevent liquid spillage outside the warehouse and thus avoid the fire from spreading.

[0003] Generally, there are two basic ways to prevent liquid spillage: one is to build a ramp outside the door of the barrel warehouse, usually 150mm to 300mm high; the other is to build a threshold at the warehouse door with a height of 150mm to 300mm, and then fill concrete on both sides of the threshold to form a ramp, which facilitates loading and unloading.

[0004] The existing conventional practices have the following drawbacks: (1) When the warehouse is converted to store liquid items, the outer door must be removed, the facade modified, and the threshold raised, resulting in material waste; (2) The sloping threshold causes the occupation of indoor and outdoor space.

[0005] In summary, a mobile liquid interception device for hazardous waste storage needs to be proposed to solve the aforementioned problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile liquid interception device for hazardous waste storage, including a support box, which is set at the entrance of the hazardous waste storage. Adjacent support boxes are connected by plug-in components. Placement slots are provided at equal intervals at the top of the support box. The placement slots are provided with transverse connecting plates through positioning components. Steel support plates are symmetrically provided at both ends of the transverse connecting plates through connecting components. The ends of the two steel support plates that are far apart from each other are in contact with the ground at the entrance of the hazardous waste storage.

[0008] Preferably, in order to facilitate the splicing of adjacent support boxes, the plug-in assembly includes plug-in slots symmetrically opened on one side of the support box, and plug-in posts symmetrically provided on the other side, with adjacent support boxes connected to each other through the plug-in slots and plug-in posts.

[0009] Preferably, to ensure the effectiveness of the insertion, the outer peripheral side of the insertion post is provided with a rubber pad that matches the insertion groove.

[0010] Preferably, in order to facilitate the insertion and positioning of the transverse connecting plate and facilitate subsequent connection with the steel support plate, the positioning component includes positioning columns symmetrically arranged under the transverse connecting plate, positioning holes matching the positioning columns are opened on the placement groove, and positioning sleeves are also provided on the inner wall of the positioning holes.

[0011] Preferably, to ensure a sealing effect, a sealing gasket is provided at the bottom of the support box.

[0012] Preferably, in order to facilitate the connection of the steel support plates, both ends are respectively connected to the support box and the ground to form a stable structural support system. The connection component includes connecting protrusions symmetrically arranged at both ends of the transverse connecting plate. Each of the two steel support plates has a connecting block at one end that is close to the other, and the connecting block has a connecting groove that matches the connecting protrusion.

[0013] Compared with the existing technology, the beneficial effects of this utility model are: it replaces the traditional method with a liquid flow interception facility, thereby achieving the goal of effectively utilizing space and saving money. The movable threshold can be assembled on site through the cooperation of the provided plug-in components, positioning components and connecting components. Except for a small number of necessary on-site operations, most of it is factory manufactured and can be placed and used directly, solving the problem of on-site construction. It can also be disassembled as needed, which is simple and convenient. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides an embodiment of a mobile liquid interception device for hazardous waste storage, comprising a support box 2 installed at the entrance 1 of the hazardous waste storage. Each support box 2 has a sealing gasket 5 adhered to its bottom end, and adjacent support boxes 2 are also fitted with sealing gaskets 5 (not shown in the figure). The number of support boxes 2 can be four, three, five, or other quantities, facilitating the sealing and interception of liquid at the entrance of the hazardous waste storage. For each support box 2, the height is 150mm, the width is 300mm, and the length is 475mm (when there are four support boxes 2), with a total length of 1900mm. For other lengths, the design is based on the hazardous waste storage entrance 1 to ensure effective interception. The support box 2 has a wall thickness of 30mm and 80mm intervals on both sides of its surface, with placement grooves 15 measuring 110mm wide × 35mm deep for connecting the steel support plate 4. The entire movable threshold (support box 2, steel support plate 4, and transverse connecting plate 3, etc.) is coated with anti-corrosion paint, with a corrosion resistance level of medium corrosion and a corrosion rate of 0.05-0.2 (mm / a). The gas type is Class C, and the annual average relative humidity is 60-75%, meeting the requirements of industrial atmospheric environment. This is a relatively mature technology and will not be discussed further here. To elaborate further, the steel support plate 4 is a component used for slope finding. Each steel support plate 4 is 30mm thick, 108mm wide, and 1230mm long. It is assembled on-site, with both ends overlapping the support box 2 and the ground at the entrance 1 of the hazardous waste storage area. The number of steel support plates 4 corresponds one-to-one with the number of placement slots 15. The slots are set according to the actual situation, ensuring that normal passage is not affected. To facilitate the connection and assembly of the steel support plates 4, positioning posts 12 with positioning components are symmetrically welded to the bottom of the transverse connecting plate 3. The placement slots 15 are provided with positioning holes 10 for easy insertion of the positioning posts 12. To ensure the effectiveness of the insertion, a positioning sleeve 11 is bonded to the inner wall of the positioning hole 10, which facilitates the placement and positioning of the transverse connecting plate 3. The two ends of the transverse connecting plate 3 are symmetrically welded (or integrally formed) with connecting protrusions 9 of the connecting components. The two steel support plates 4 are each welded with a connecting block 13 (angle steel support, 30mm thick, 100mm wide) at their close ends. The connecting block 13 has a connecting groove 14 that connects with the connecting protrusion 9, which facilitates the connection of the transverse connecting plate 3 to the end of the steel support plate 4. The two ends are respectively connected to the support box 2 and the ground to form a stable structural support system.

[0021] To facilitate assembly and connection between adjacent support boxes 2, one side of each support box 2 has a plug-in slot 6 for the plug-in assembly, and the other side has a plug-in post 7. This allows adjacent support boxes 2 to be plugged in using the plug-in slot 6 and the plug-in post 7. Rubber pads 8 are adhered to the periphery of the plug-in post 7 to ensure the plugging effect. For the two outermost support boxes 2, one support box 2 has a plug-in slot 6 on its side wall, and the other support box 2 has a plug-in post 7 welded to its side wall. The outermost side wall does not have a plug-in slot 6 or a welded plug-in post 7. Furthermore, a sealing layer (not shown in the figure) is adhered to the side walls of the two outermost support boxes 2 that are far apart from each other, which ensures a sealing effect with the hazardous waste storage door 1 and guarantees the interception effect.

[0022] Working principle: When using this utility model, the support box 2 is transported to the entrance 1 of the hazardous waste storage to be intercepted. The adjacent support boxes 2 can be connected and assembled by the insertion slot 6 and the insertion post 7. The rubber pad 8 ensures the insertion effect. The sealing gasket 5 at the bottom of the support box 2 is in contact with the ground to ensure the interception effect. In order not to affect the passage of transport vehicles, the transverse connecting plate 3 is inserted into the placement slot 15. The transverse connecting plate 3 can be inserted by the positioning post 12, the positioning hole 10 and the positioning sleeve 11. Then, with the connecting groove 14 on the connecting block 13 and the connecting protrusions 9 at both ends of the transverse connecting plate 3, the steel support plate 4 can be connected and assembled. The two ends are respectively connected to the support box 2 and the ground to form a stable structural support system.
