Description

Technical Field

[0001] The invention relates to the technical field of floor drains, in particular to a floor connection compensation cover for an explosion-proof floor drain at the opening of a civil air defense basement. Background Art

[0002] A floor drain is a device that works with a drainage pipe to divert liquids such as sewage from the ground. Floor drains usually also have insect and odor prevention functions, so that insects and odors in the drainage pipe will not be absorbed into the home environment through the floor drain, helping to make the floor drain use environment cleaner and more hygienic. In addition to the widespread use of floor drains in homes, floor drains can be seen in shopping malls, squares, and civil air defense basements. Among them, floor drains in civil air defense projects are more special. Civil air defense basements serve as temporary air defense shelters for people. They are commonly found in basements in various communities and have certain air defense and gas prevention safety functions. In addition, in order to deal with rainwater entering the air defense basement on rainy days, multiple floor drains and drainage pipes will be set up in the civil air defense basement to drain the water from the basement, reduce accumulation in the basement, and cause abnormal conditions such as excessive humidity in the basement.

[0003] However, during the construction of a civil air defense basement, the explosion-proof floor drains used for civil air defense are usually laid together with the basement floor slabs. After completion, a waterproof layer needs to be laid on the surface of the floor slabs, and a building surface layer needs to be laid on top of the waterproof layer. The building surface layer has a certain thickness, so for people on the surface of the building surface layer in the civil air defense basement, the explosion-proof floor drain is at a height lower than the building surface layer. Although grooves are cut on the surface of the building surface layer during construction to connect the surface of the building surface layer with the inner cavity of the floor drain, thereby ensuring the perfection of the drainage function of the civil air defense basement, it still affects the use of the explosion-proof floor drain. For example, the grooves on the building surface cause people in the basement to accidentally step on the grooves on the building surface during movement, which can easily cause people to fall and get injured. In addition, impurities and garbage in the civil air defense basement are easily accumulated in the grooves on the building surface, which leads to a large amount of impurities on the surface of the explosion-proof floor drain and causes blockage, which is difficult for sanitation workers to clean. In addition, the blockage of the explosion-proof floor drain affects the drainage function of the civil air defense basement. For this purpose, a floor connection compensation cover for the explosion-proof floor drain at the mouth of the civil air defense basement is provided. Summary of the Invention

[0004] The purpose of the present invention is to provide a floor connection compensation cover for an explosion-proof floor drain at the entrance of a civil air defense basement, which has the advantage of facilitating the normal use of the floor drain and solves the problem that during the construction process, the surface of the building surface is grooved to connect the surface of the building surface with the inner cavity of the floor drain, thereby ensuring the perfection of the drainage function of the civil air defense basement. However, it still affects the use of the explosion-proof floor drain, including that the grooves on the building surface cause people in the basement to accidentally step on the grooves on the building surface during their movements, and they are prone to fall and get injured after stepping on empty air. In addition, impurities and garbage in the civil air defense basement are easily accumulated in the grooves on the building surface, which then leads to a large amount of impurities on the surface of the explosion-proof floor drain and blockage, which is difficult for sanitation workers to clean. In addition, the blockage of the explosion-proof floor drain affects the drainage function of the civil air defense basement.

The movable connection between the first compensation ring and the second compensation ring can add a height adjustment function to the first compensation ring and the second compensation ring, so that the device can adapt to the depth of the through grooves opened on the surface of different building surface bodies. According to the specific depth of the through grooves opened on the surface of different building surface bodies, the height between the first compensation ring and the second compensation ring is adjusted when using the device.

By arranging the basement floor body 1, the explosion-proof floor drain body 2, the drainage pipe body 3, the building surface body 4, the first compensation ring 5, the second compensation ring 6, the penetration groove 7, the expansion screw 8, the compensation cover body 9 and the interception plate 10, the basement floor body 1 provides basic support for the explosion-proof floor drain body 2, and the explosion-proof floor drain body 2 cooperates with the drainage pipe body 3 to be connected with the external sewage pipe, so as to achieve the purpose of diverting and draining the sewage on the top of the first compensation ring 5 The function of water can reduce the possibility of a large amount of water accumulation on the surface of the building surface body 4. The movable connection between the first compensation ring 5 and the second compensation ring 6 can add a height adjustment function to the first compensation ring 5 and the second compensation ring 6, so that the device can adapt to the depth of the through groove opened on the surface of different building surface bodies 4. According to the specific depth of the through groove opened on the surface of different building surface bodies 4, the height between the first compensation ring 5 and the second compensation ring 6 is adjusted when using the device. After the first compensation ring 5 and the second compensation ring 6 are fixed to the building surface body 4 respectively with the expansion screws 8 and bolts, the compensation cover body 9 is used to cover the top of the first compensation ring 5 and the second compensation ring 6, so that the device can be level with the surface of the building surface body 4 and provide explosion-proof floor drain The height of the main body 2 and the top of the building surface body 4 is compensated, thereby preventing people from stepping on the inner cavity of the through groove on the surface of the building surface body 4 and falling down due to weak ambient light when walking in the civil air defense basement. In addition, due to the compensation of the through groove height, the impurities and dust in the civil air defense basement are easily accumulated in the inner cavity of the through groove on the top of the building surface body 4, which then causes the possibility of blockage of the explosion-proof floor drain body 2 and the drainage pipe body 3. The problem of the surface of the building surface being grooved during construction to connect the surface of the building surface with the inner cavity of the floor drain is solved, which ensures the perfection of the drainage function of the civil air defense basement. However, it still affects the use of the explosion-proof floor drain, including the grooves on the surface of the building, which make people in the basement fall down during movement.Accidentally stepping on the grooves on the building surface can easily cause people to fall and get injured. In addition, impurities and garbage in the civil air defense basement are easily accumulated in the grooves on the building surface, which in turn causes a large amount of impurities on the surface of the explosion-proof floor drain and causes blockage, which is difficult for sanitation workers to clean. The blockage of the explosion-proof floor drain also affects the drainage function of the civil air defense basement.

[0022] Specifically, a slide groove 11 is provided on both sides of the inner cavity surface of the first compensation ring 5, and a slider 12 is fixedly connected to both sides of the surface of the second compensation ring 6. One end of the slider 12 extends to the inner cavity of the slide groove 11 and is movably connected to the inner cavity of the slide groove 11. By setting the slide groove 11 and the slider 12, the slider 12 extends to the inner cavity of the slide groove 11, thereby limiting the displacement trajectory of the second compensation ring 6 in the inner cavity of the first compensation ring 5, so that the second compensation ring 6 only follows the inner cavity of the slide groove 11 for height adjustment, thereby increasing the stability of the first compensation ring 5 and the second compensation ring 6 during adjustment.

[0023] Specifically, the lower end of the inner cavity surface of the first compensation ring 5 is fixedly connected to a support ring 13, and the bottom of the second compensation ring 6 is movably connected to the top of the support ring 13. The support ring 13 is located directly below the slide groove 11. By setting the support ring 13, the second compensation ring 6 is supported and further limited to prevent the second compensation ring 6 from moving downward under the action of gravity.

[0024] Specifically, sealing rings 14 are fixedly connected to the four sides of the bottom of the first compensation ring 5, and an explosion-proof cover 15 is movably connected to the top of the explosion-proof floor drain body 2. The bottom of the sealing ring 14 is in contact with the top of the explosion-proof cover 15. By setting the sealing ring 14 and the explosion-proof cover 15, the sealing ring 14 increases the sealing performance between the inner cavity of the first compensation ring 5 and the top of the explosion-proof cover 15, reducing the accumulation of water on the top of the building surface body 4 from flowing out through the gap between the first compensation ring 5 and the explosion-proof cover 15 during drainage.

[0025] Specifically, the first limiting ring 16 and the second limiting ring 17 are fixedly connected to the four sides of the bottom of the compensation cover body 9, the surface of the inner cavity of the first limiting ring 16 is movably connected to the surface of the second compensation ring 6, and the surface of the second limiting ring 17 is movably connected to the surface of the inner cavity of the second compensation ring 6. By setting the first limiting ring 16 and the second limiting ring 17, the installation of the compensation cover body 9 is limited, and at the same time, the liquid outflow through the gap between the compensation cover body 9 and the second compensation ring 6 during drainage is reduced.

[0026] Specifically, a sealing ring 18 is fixedly connected to one side of the penetration groove 7, and the sealing ring 18 cooperates with the first compensation ring 5 and the second compensation ring 6. By providing the sealing ring 18, the possibility of liquid leaking through the gap between the bolt and the penetration groove 7 during the drainage of the inner cavity of the first compensation ring 5 and the second compensation ring 6 is reduced.

[0027] When in use, first use an external measuring caliper to measure the distance between the top of the building surface body 4 and the top of the explosion-proof cover 15. After completion, adjust the height of the first compensation ring 5 and the second compensation ring 6 according to the measured size, and use the external measuring caliper again to measure the distance between the two penetration grooves 7 on the surface of the first compensation ring 5 and the second compensation ring 6. According to the measurement results, use an external electric drill to drill in the inner cavity of the through groove at the top of the building surface body 4, and use a hammer to knock the expansion screw 8 into the inner cavity of the drilled hole, and then place the first compensation ring 5 and the second compensation ring 6 with the adjusted height into the inner cavity of the through groove at the top of the building surface body 4, and let the sealing ring 14 contact the top of the explosion-proof cover 15. After completion, use a bolt to penetrate the sealing ring 18 and the penetration groove 7 and extend to the inner cavity of the expansion screw 8, and thread it with the inner cavity of the expansion screw 8. Finally, use the compensation cover body 9 to allow the top of the second compensation ring 6 to extend between the first limit ring 16 and the second limit ring 17 to prevent people from walking in the civil defense basement. When walking, the possibility of stepping on the inner cavity of the groove on the surface of the building surface body 4 and falling down, causing a safety accident due to the weak ambient light. In addition, due to the compensation of the groove height, the impurities and dust in the civil air defense basement are easily accumulated in the inner cavity of the groove on the top of the building surface body 4, which then causes the explosion-proof floor drain body 2 and the drainage pipe body 3 to be blocked. This solves the problem that during the construction process, the surface of the building surface will be grooved to connect the surface of the building surface with the inner cavity of the floor drain, ensuring the perfection of the drainage function of the civil air defense basement, but it still affects the use of the explosion-proof floor drain. For example, the grooves on the building surface make people in the basement accidentally step on the grooves on the building surface during movement, and they are likely to fall and get injured after stepping on air. In addition, impurities and garbage in the civil air defense basement are easily accumulated in the grooves on the building surface, which then causes a large amount of impurities on the surface of the explosion-proof floor drain and causes blockage, which is difficult for sanitation workers to clean. Moreover, the drainage function of the civil air defense basement is affected due to the blockage of the explosion-proof floor drain.
