For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0038] The present disclosure will be described in detail below with reference to the drawings and in conjunction with embodiments.
[0039] First, please refer to Figures 1 to 3 , Figure 1 is an exploded view of an embodiment of the floor drain device with electromagnetic shielding function of the utility model; Figure 2 is a structure schematic view of the grate cover plate, floor drain inner core and assembled panel of the utility model; Figure 3 is a sectional view of an embodiment of the floor drain device with electromagnetic shielding function of the utility model. As Figure 1 and Figure 3 shown, the floor drain device with electromagnetic shielding function includes a grate cover plate 1, a floor drain inner core 2, a metal mesh gasket 3, a panel 4, a sleeve 5, a threaded flange 6 and a drainage pipeline 7.
[0040] Next, please refer to Figure 4 , Figure 4 is a structure schematic view of an embodiment of the grate cover plate of the utility model. As Figure 4As shown in the drawings, the grate cover plate 1 can be made of punched stainless steel plate. A plurality of water guide lines 11 can be arranged around the axis on the upper surface of the grate cover plate 1. The water guide lines 11 can be curved and can be arranged in clockwise or counterclockwise direction according to different regions, so as to guide the water flow to the middle of the grate cover plate 1.
[0041] A plurality of water permeable holes 12 are arranged between the adjacent water guide lines 11, and the diameter of the water permeable holes 12 gradually decreases as approaching the axis of the grate cover plate 1. In this way, the outer large-diameter water permeable holes 12 can flow more water, thereby improving the drainage efficiency. The inner water permeable holes 12 with decreasing diameter can adapt to the flow of water, because the water flow gradually decreases after passing through the outer large-diameter water permeable holes 12. Meanwhile, the water permeable holes 12 with different diameters can also perform multi-stage filtering on sundries, thereby avoiding the clogging of the floor drain device. As an example, the largest diameter of the water permeable holes 12 can be less than one third of the thickness of the grate cover plate 1.
[0042] Further, a handle 13 can be arranged at the center of the upper surface of the grate cover plate 1, so as to facilitate the disassembly and assembly of the grate cover plate 1 and improve the work efficiency.
[0043] Referring back to Figures 1 to 3 , the panel 4 can be made of stainless steel material, and the upper end of the inner portion of the panel 4 is provided with a first accommodating space for placing the grate cover plate 1. The lower end of the inner portion of the panel 4 is provided with a second accommodating space in communication with the first accommodating space, and the inner wall of the second accommodating space is provided with internal threads.
[0044] Referring to Figure 4 and continuing to refer to Figures 1 to 3 , Figure 4 is a structural schematic view of an embodiment of the grate cover plate of the utility model. As shown in the drawings, Figures 1 to 4 , the floor drain inner core 2 can be a stainless steel gravity type floor drain inner core, and the outer edge of the floor drain inner core 2 can be provided with external threads matched with the internal threads of the inner wall of the second accommodating space. In the assembled state, the floor drain inner core 2 is detachably inserted into the second accommodating space through the external threads.
[0045] The top of the floor drain inner core 2 can be provided with an outer ring 21 matched with the size of the first accommodating space, and in the assembled state, the outer ring 21 is engaged with the bottom of the first accommodating space, thereby limiting the installation position of the floor drain inner core 2. Further, a metal mesh gasket 3 can be sleeved between the outer ring 21 and the bottom of the first accommodating space, thereby enhancing the sealing property of the floor drain inner core 2 and the panel 4.
[0046] In the drainage state, the water baffle 22 of the floor drain inner core 2 is Figure 4The opening is shown. In the waterless state, the water baffle 22 of the floor drain inner core 2 is shown as Figure 1 The closing is shown.
[0047] The sleeve 5 can be made of stainless steel, and the upper end of the sleeve 5 is connected to the bottom of the floor drain inner core 2. Those skilled in the art can select the connection method according to the actual situation, such as insertion, sleeve, threaded connection, etc. The length and diameter of the sleeve 5 can be adjusted according to the actual situation.
[0048] Next, please refer to Figure 6 , Figure 6 is a structural schematic view of an embodiment of the threaded flange of the utility model. As shown in Figure 6 , the threaded flange 6 can be made of galvanized steel, including a pair of wires 62 and a flange plate 61, and the flange plate 61 is fixedly sleeved in the middle of the pair of wires 62. The upper end of the threaded flange 6 is connected to the lower end of the sleeve 5 through external threads, and the lower end of the threaded flange 6 is screwed with the lower drainage pipeline 7. The drainage pipeline 7 can be made of PVC material. In the case of installing the floor drain device, the flange plate 61 is welded with the shield buried underground.
[0049] In actual use, since the grate cover plate 1 and the floor drain inner core 2 are detachably connected with the panel 4, it is convenient for cleaning and maintenance replacement.
[0050] Finally, please refer to Figure 7 , Figure 7 is a structural schematic view of another embodiment of the floor drain device with electromagnetic shielding function of the utility model. As shown in Figure 7 , on the ground surface that needs electromagnetic shielding, usually on the bedrock, gravel or pebbles, plastic film or impermeable geotextile, waterproof concrete cushion, steel plate shield and waterproof concrete are laid in turn. When installing the floor drain device, first lay the drainage pipeline 7 according to the design requirements or relevant specifications. The above-mentioned steel plate shield is cut, and the flange plate 61 installation position is reserved. Next, connect the threaded flange 6 on the drainage pipeline 7, and stably weld the flange plate 61 with the steel plate shield. Then cut the sleeve 5 of corresponding length according to the actual situation or design requirements and complete the connection with the threaded flange 6. Finally, install the panel 4, metal mesh gasket 3, floor drain inner core 2 and grate cover plate 1 in turn. It should be noted that the panel 4 and the threaded flange 6 should not be filled with cement mortar or jointing agent and other non-conductive materials during installation, so as to ensure the integrity of electromagnetic shielding.
[0051] It should be noted that in some oil storage rooms, when electromagnetic shielding is required, the floor drain is typically required to be 150mm-200mm above the ground. This requirement can be met by cutting the sleeve 5 to the corresponding length. In other words, the floor drain device of this invention can be adapted to different engineering needs by changing the length of the sleeve 5.
[0052] This floor drain device provides effective electromagnetic shielding in both waterless and permeable conditions. In the waterless condition, the baffle 22 inside the floor drain core 2 functions as follows: Figure 1 The diagram shows the closed state. Because the flange 61 of the threaded flange 6 is welded to the steel plate shield, the threaded flange 6, sleeve 5, panel 4, and grate cover 1 form the first effective layer of shielding protection. Furthermore, because the baffle plate 22 is closed, the threaded flange 6, sleeve 5, panel 4, and drain core 2 form the second effective layer of shielding protection.
[0053] During water permeation, the baffle plate 22 inside the drain core 2, as... Figure 5 In the open state shown, the first effective shielding protection formed by the threaded flange 6, sleeve 5, panel 4, and grate cover 1 can still play an electromagnetic shielding role.
[0054] This utility model of a floor drain device with electromagnetic shielding function not only meets the requirements for electromagnetic shielding effectiveness, but also solves the problems of blockage, corrosion, and detachment commonly found in existing floor drains. It also boasts advantages such as low cost, easy installation, and convenient maintenance.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
