Description

Technical Field

[0001] This utility model relates to the field of civil defense engineering equipment, specifically to an explosion-proof sealing cover for a floor drain in civil defense engineering. Background Technology

[0002] Explosion-proof floor drains are used at the inner end of the drainage pipe network in civil defense areas to prevent toxic gases and blast waves from entering the protective structure through pipes. When sealed, they can prevent blast shock waves and other toxic gases from entering the protective structure through pipes, thus playing a safety protection role. In wartime, when the area is contaminated and needs to be cleaned, the explosion-proof floor drain can be opened to drain water for flushing.

[0003] Since existing floor drains are usually exposed to the outside, dust will accumulate in them after a long period of use, causing them to become clogged. Therefore, people install dust covers to prevent dust from accumulating and clogging the floor drains. For example, Chinese utility model patent with announcement number CN217325712U discloses an explosion-proof floor drain for civil defense projects.

[0004] However, in actual use, it is found that the dustproof plate is fixed by connecting the clip to the plate. Although this fixing method is relatively quick, the stability of the dustproof plate in the process of preventing dust from entering the floor drain is poor. The dustproof plate may separate from the floor drain, thus failing to guarantee the dustproof function of the dustproof cover. How to invent a sealing cover to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an explosion-proof sealing cover for floor drains in civil defense projects, which aims to solve the problem of poor stability of dustproof plates during the dustproofing process of floor drains.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an explosion-proof sealing cover for a floor drain in civil defense engineering, including a floor drain body and a dust cover. The floor drain body has an internal cavity, and a cover plate, a water outlet pipe, and a pressure plate are arranged inside the cavity. The side of the cover plate near the water outlet pipe is connected to the pressure plate. A plug is fixed on the pressure plate and inserted into the end of the water outlet pipe. Several locking blocks are machined on the inner wall of the floor drain body, and locking blocks are arranged between the locking blocks. Several threaded rods are threaded to the side of the floor drain body, and the threaded rods are fixedly connected to the locking blocks. The inner side of each locking block is in contact with the cover plate. A first handle is rotatably connected to the side of the dust cover away from the cover plate. A groove is formed on the side of the dust cover near the cover plate, and a rod and a gear are connected inside the groove. The gear is fixedly connected to the first handle.

[0008] Preferably, a second handle is fixedly connected to the side of the cover plate near the dust cover, and the second handle fits into the groove, with the insertion rod passing laterally through the second handle; this facilitates improved stability of the dust cover.

[0009] Preferably, the cover plate has several protrusions machined on its side, the protrusions are disposed between the locking blocks, and a pin is provided on the inner side of the locking block; this helps to improve the stability of the cover plate in the cavity.

[0010] Preferably, a plurality of elastic components are fixedly connected between the pressure plate and the cover plate, and each elastic component is provided with a telescopic rod inside; to prevent gas in the water outlet pipe from entering the floor drain.

[0011] Preferably, one side of the insertion rod is machined with teeth, the gear meshes with the insertion rod, the insertion rod is slidably connected to the dust cover, and the gear is rotatably connected to the dust cover; this facilitates the fixing of the dust cover to the cover plate.

[0012] Preferably, the dust cover has several slots on the side near the cover plate, the slots are arranged in a circular array, and the blocks fit into the slots; this improves the stability of the dust cover on the drain body.

[0013] The beneficial effects of this utility model are: 1. This explosion-proof sealing cover for floor drains in civil defense projects features a first handle and a second handle on the dust cover and the cover plate, respectively. Users can fix the position of the dust cover by rotating the handles. Since the handles on the dust cover are connected to gears, and a movable insert is engaged with the gears, a connection structure is provided to fix the dust cover and the cover plate. This improves the stability of the dust cover on the floor drain, ensures the dustproof effect of the dust cover, prevents separation of the dust cover and the cover plate, and enhances the connection strength between the dust cover and the cover plate. The structure is simple, highly reliable, and provides convenience for dustproofing floor drains. 2. This explosion-proof sealing cover for a civil defense engineering floor drain, by setting multiple locking blocks and clamping blocks inside the floor drain, can simultaneously limit the position of the cover plate and the dust cover, making it convenient for people to quickly install the cover plate and the dust cover on the floor drain. The locking block is moved by the cooperation of the screw rod and the locking block, which has good stability and saves people's installation time in fixing the cover plate. The dust cover is limited by the slot and the locking block, which further improves the stability of the cover plate and the dust cover on the floor drain. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example, refer to Figures 1-5 An explosion-proof sealing cover for a floor drain in a civil defense project includes a floor drain body 1 and a dust cover 5. The drain body 1 has a cavity 17 inside, and a cover plate 4, a water outlet pipe 7 and a pressure plate 3 are installed inside the cavity 17. The side of the cover plate 4 near the water outlet pipe 7 is connected to the pressure plate 3. A plug 11 is fixed on the pressure plate 3 and is inserted into the end of the water outlet pipe 7. Several locking blocks 8 are machined on the inner wall of the drain body 1, and locking blocks 2 are installed between the locking blocks 8. Several threaded rods 16 are threaded to the side of the drain body 1 and are fixedly connected to the locking blocks 2. The inner side of the locking blocks 2 is all in contact with the cover plate 4. A first handle 6 is rotatably connected to the side of the dust cover 5 away from the cover plate 4. A groove 15 is opened on the side of the dust cover 5 near the cover plate 4. A rod 14 and a gear 13 are connected inside the groove 15 and the gear 13 is fixedly connected to the first handle 6.

[0019] Furthermore, a second handle 9 is fixedly connected to the side of the cover plate 4 near the dust cover 5, and the second handle 9 fits into the groove 15 and the insertion rod 14 passes through the second handle 9 laterally.

[0020] It should be noted that by setting a second handle 9 on the cover plate 4 and cooperating with the insertion rod 14, the dust cover 5 can be fixed to the cover plate 4, which can improve the stability of the dust cover 5.

[0021] Furthermore, the cover plate 4 has several protrusions machined on its side, which are arranged between the locking blocks 8, and a pin is provided on the inner side of the locking block 2.

[0022] It should be noted that by setting a pin on the locking block 2 and a protrusion on the side of the cover plate 4, the cover plate 4 can be fixed inside the cavity 17 in conjunction with the locking block 2, which helps to improve the stability of the cover plate 4 inside the cavity 17.

[0023] Furthermore, a number of elastic components 10 are fixedly connected between the pressure plate 3 and the cover plate 4, and each elastic component 10 is provided with a telescopic rod.

[0024] It should be noted that by providing an elastic part between the pressure plate 3 and the cover plate 4, the pressure plate 3 can be buffered, so that the pressure plate 3 and the plug 11 are always locked with the water outlet pipe 7, preventing the gas in the water outlet pipe 7 from entering the floor drain.

[0025] Furthermore, one side of the insertion rod 14 is machined with teeth, the gear 13 meshes with the insertion rod 14, the insertion rod 14 is slidably connected to the dust cover 5, and the gear 13 is rotatably connected to the dust cover 5.

[0026] It should be noted that by setting gear 13 and insert rod 14 inside the dust cover 5, people can control the insert rod 14 to slide in the groove 15, which makes it convenient for people to fix the dust cover 5 to the cover plate 4.

[0027] Furthermore, the dust cover 5 has several slots 12 on the side near the cover plate 4. The slots 12 are arranged in a circular array, and the blocks 8 are all in contact with the slots 12.

[0028] It should be noted that by opening a slot 12 on the dust cover 5 and fitting it with the card block 8, the dust cover 5 can be limited, which further improves the stability of the dust cover 5 on the drain body 1.

[0029] The working principle of this explosion-proof sealing cover for civil defense engineering floor drains is as follows: When in use, the water outlet pipe 7 is inserted into the cavity 17 of the floor drain body 1. During installation, the cover plate 4 is first placed into the cavity 17 along with the corresponding locking block 8, so that the plug 11 on the pressure plate 3 blocks the water outlet pipe 7. The cover plate 4 is then pressed down, so that the elastic component 10 and the pressure plate 3 maintain a certain pressure on the water outlet pipe 7. Then, the screw 16 on the side of the floor drain body 1 is rotated, and the locking block 2 is controlled by the limiting control of the locking block 8 to fit against the side of the cover plate 4 until the locking block 2 fixes the cover plate 4 in the cavity 17 from the side. Next, the slot 12 on one side of the dust cover 5 is also fitted against the locking block 8, so that the second handle 9 enters the groove 15. Then, the first handle 6 on the dust cover 5 is rotated, so that the gear 13 drives the insertion rod 14 to pass through the second handle 9 laterally, thereby fixing the dust cover 5, the cover plate 4, and the floor drain body 1.

[0030] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
