Description

Technical Field

[0001] This utility model relates to the field of reserved hole protection technology, and in particular to a reserved hole protection structure. Background Technology

[0002] Reserving openings during construction is an important technical measure, mainly to meet the needs of building functions, equipment installation, and later maintenance. However, these reserved openings are often not effectively protected, which not only makes it easy for people to fall in, but also for construction debris to fall in, creating safety hazards. However, for the sake of construction needs, these reserved openings cannot be completely sealed.

[0003] A search revealed that Chinese patent CN202220394819.0 discloses a protective device for pre-reserved holes in building construction. Fixed modules are installed along the edge of the hole, and two oppositely positioned fixed modules are connected to each other via a telescopic device in a detachable structure, thus completing the protection of the pre-reserved hole. This combined protective device, constructed using multiple fixed modules and a detachable structure, is suitable for pre-reserved holes of different shapes and sizes. It effectively improves installation and protection capabilities while offering simple and quick installation and disassembly, and flexible and convenient use. Furthermore, it can be standardized and mass-produced in factories, resulting in low manufacturing costs. After use, it can be disassembled and stored, allowing for long-term repeated use and occupying minimal space.

[0004] The above-mentioned technical solution has the following drawbacks. Although such a pre-reserved hole protection structure can support and intercept the pre-reserved hole through multiple sets of support rods, thereby preventing large pieces of garbage from falling through the hole and having good applicability, in actual use, the hole is only supported at various points. During the support process, the hole wall is easily cracked due to stress, causing safety hazards. In order to further improve the protective effect of the pre-reserved hole, a new pre-reserved hole protection structure is proposed. It can be adapted to holes of different sizes for quick installation and has a sealing effect. It can not only prevent debris from passing through but also prevent water seepage, thus having a better protective effect. It also has adjustable and quick disassembly and assembly functions. It can be quickly locked to the edge of the hole for installation. It is equipped with a warning structure to provide warning at night and on cloudy days with low light. It is equipped with an openable and closable drainage hole and a filter screen that can be opened when necessary to drain water and prevent water accumulation and blockage.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a pre-drilled hole protection structure, which solves the problems mentioned in the background. It can be adapted to holes of different sizes for quick installation and has a better protective effect. It is also adjustable and quick to install and remove. It can be quickly locked to the edge of the hole for installation. A warning structure is provided to improve safety. It is equipped with an openable and closable drainage hole and a filter screen that can be opened when necessary to drain water and prevent water accumulation and blockage.

[0008] The present invention provides the following solution to the above-mentioned technical problems: a pre-reserved hole protection structure, comprising a hole sealing plate, a hole plugging cylinder, an intercepting net, and a sealing cover. The hole plugging cylinder is connected to the hole sealing plate by screws. The hole plugging cylinder is equipped with a sealing rubber airbag. The hole sealing plate is equipped with a lower rubber airbag. The hole sealing plate is equipped with a handle, a first inflation valve, a second inflation valve, and an airbag pressure sensor. The intercepting net is fixedly equipped with an annular frame. The annular frame is connected to the hole sealing plate by screws. The annular frame is threadedly connected to the sealing cover. The sealing cover is equipped with an LED flashing warning light and a reflective warning sticker. The first inflation valve is connected to the lower rubber airbag.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the hole sealing cylinder has a groove corresponding to the sealing rubber airbag, and the sealing rubber airbag is configured as a ring structure and loaded in the groove, so that the rubber airbag can be stably set around the hole sealing cylinder, thereby sealing the gap between the hole sealing cylinder and the reserved hole.

[0011] Furthermore, the grip is provided in two parts, which are respectively placed on both sides of the hole sealing plate, making it easy to lift the hole sealing plate.

[0012] Furthermore, a sealing ring is provided at the gap between the annular frame and the sealing cover to prevent water from seeping out through the gap between the annular frame and the sealing cover.

[0013] Furthermore, the hole sealing plate has a water leakage hole, and the annular frame is fixedly installed with an insertion tube corresponding to the water leakage hole. The insertion tube is inserted into the water leakage hole, so that the annular frame can be stably placed at the hole sealing plate.

[0014] Furthermore, both the second inflation valve and the airbag pressure sensor are equipped with threaded connectors. The second inflation valve and the airbag pressure sensor can be connected to the sealing rubber airbag through the threaded connectors, so that the second inflation valve and the airbag pressure sensor can be stably connected to the sealing rubber airbag.

[0015] Furthermore, both the No. 1 and No. 2 inflation valves are threadedly connected to sealing caps, which can stably seal the No. 1 and No. 2 inflation valves.

[0016] Furthermore, the lower rubber airbag is configured as an annular structure, and the bottom of the hole sealing plate is provided with an annular groove corresponding to the lower rubber airbag. The annular lower rubber airbag can be sealed around the hole sealing plate.

[0017] This utility model provides a pre-reserved hole protection structure, which has the following advantages:

[0018] 1. Cover the hole with the hole sealing plate and insert the hole sealing cylinder into the hole. Inflate the sealing rubber airbag of the hole sealing cylinder through the No. 2 inflation valve. The airbag pressure sensor can detect the air pressure inside the sealing rubber airbag. The sealing rubber airbag can then seal the gap between the hole sealing cylinder and the hole and lock in place. As the first line of sealing protection, it can be installed in pre-drilled holes of different diameters and has good applicability.

[0019] 2. The lower rubber airbag can be inflated through the No. 1 inflation valve. The inflated lower rubber airbag can seal the gap between the hole cover plate and the ground, thus serving as a second layer of sealing protection.

[0020] 3. The LED flashing warning lights and reflective warning stickers on the surface of the sealing cover can warn people in the surrounding area. If there is water accumulation, it needs to be drained through the reserved holes. Unscrew the sealing cover and the water can be drained through the ring frame. The interception net can intercept and handle debris in the water, thereby preventing blockage and debris from falling.

[0021] 4. This pre-drilled hole protection structure can be adapted to holes of different sizes for quick installation and has a sealing effect. It can not only prevent debris from passing through but also prevent water seepage, providing better protection. It is also adjustable and quick to install and remove. It can be quickly locked to the edge of the hole for installation. It is equipped with a warning structure to provide warning at night and on cloudy days when the fiber optic cable is dark. It is equipped with an openable and closable drainage hole and a filter screen that can be opened when necessary to drain water and prevent water accumulation and blockage.
