Description

Technical Field

[0001] This utility model belongs to the field of building construction, and specifically relates to an opening covering and enclosure device. Background Technology

[0002] Bored pile foundations are constructed by manually excavating the soil to create the pile hole. While excavating downwards, the hole wall is lined to ensure construction safety. After cleaning the bottom of the hole, concrete is poured. This method can create large-diameter piles, meeting the urgent need for large-diameter piles in high-rise buildings. In new energy power generation projects, various power generation units need to collect their respective electrical energy and transmit it to substations or, after collection at substations, to the power grid. Ensuring green, environmentally friendly, and economical practices is essential, and the number of towers is increasing exponentially. For tower foundations, whether 35kV, 110kV, or higher voltage levels, bored pile foundations are fundamental. Currently, manual excavation is used, but bored pile construction is inherently a high-risk project, requiring strict safety precautions during construction.

[0003] When manually excavated bored piles for the foundation of the iron tower are completed, the bored piles need to be temporarily sealed and the edge protection needs to be done. Traditionally, fences are used for edge protection and cover plates are used to cover the holes. Both steps are carried out separately. The fences and hole cover plates are not well integrated, resulting in poor stability. When either the fence or the cover plate fails, it can easily cause the other to shift. Therefore, the performance of the safety protection needs to be further improved. Utility Model Content

[0004] The present invention aims to provide an orifice covering and enclosure device to solve the problems of poor stability and insufficient safety protection performance of existing fences and orifice covers.

[0005] An orifice covering and enclosure device in this solution includes multiple detachably connected enclosure panels for forming a fence. Each enclosure panel has a sub-cover plate rotatably connected to its lower end. The multiple sub-cover plates can be detachably spliced ​​into a combined cover plate. The fence is fixed to the inner wall of the orifice, and the combined cover plate covers the orifice.

[0006] The working principle and beneficial technical effects of this solution are as follows: After multiple enclosure panels are combined to form a fence, the individual cover plates are stably spliced ​​inside the fence. The combined fence and the combined cover plates mutually constrain each other in position, improving overall integrity and stability, making it less prone to failure for either the enclosure panels or the individual cover plates. The fence abuts against the inner wall of the borehole to fix the soil of the borehole wall, while the internal combined cover plates cover the borehole, thereby achieving temporary closure of the borehole pile and providing excellent edge protection.

[0007] In this solution, the fencing device can be disassembled and reassembled, and can be reused. The disassembled cover plate and the fencing plate can be folded together, making transportation and storage extremely convenient. It is very suitable for outdoor construction and reduces site clutter.

[0008] Furthermore, the fence panels are equipped with male and female buckles on both sides, and adjacent fence panels are connected by these buckles. The male and female buckles are extremely convenient to connect and disassemble, have a relatively simple structure, and ensure connection stability.

[0009] Furthermore, the yin-yang buckle is a combination of tenon and mortise buckle or clasp and pin; the cover plates are connected by a combination of pin and clasp.

[0010] Furthermore, the enclosure panel is rectangular, and the cover plate is triangular. Triangles inherently possess excellent stability.

[0011] Furthermore, the sub-cover plates are isosceles right triangles. Since all sub-cover plates are the same size, the overall stability is better, and assembly is more convenient.

[0012] Furthermore, the inclined edge of the cover plate is connected to the enclosure plate by any one or more combinations of hinge connection, pin connection, and shaft connection.

[0013] Furthermore, the two vertical edges of the cover plate are connected by cables, and the enclosure plate has two through holes. The two cables on the cover plate pass through one of the through holes from the inside of the enclosure and are movably connected to the outside of the enclosure. The movable ends of the cables are connected to the rear side of the enclosure plate (outside the enclosure), limiting the position of the cover plate and the enclosure plate, and better securing the cover plate in its covering function to prevent it from collapsing under gravity. Additionally, when the device is disassembled, the cover plate and the enclosure plate are folded along the rotating connection, and the cables act as a kind of binding, preventing the cover plate and the enclosure plate from flipping over during transportation.

[0014] Furthermore, a hook is provided at the end of the cable away from the cover plate. The hook facilitates connection and disconnection. Attached Figure Description

[0018] The following detailed description illustrates the specific implementation method:

[0019] The reference numerals in the accompanying drawings of the instruction manual include: 1. enclosure panel, 2. cover plate, 3. hinge, 4. cable, 5. buckle, 6. lock, 7. pin, 8. through hole, 9. mortise, and 10. tenon.

[0020] The basic implementation examples are as follows: Figure 1 , Figure 2 and Figure 3 As shown: An orifice covering and enclosure device includes four enclosure panels 1 connected by mortise and tenon joints to form an enclosure. Specifically, one side of the lower end of each enclosure panel 1 has a tenon 10, and the other side has a mortise 9 that matches the tenon 10. Each enclosure panel 1 has a separate cover plate 2 rotatably connected to its lower end via a hinge 3. The separate cover plate 2 is in the shape of an isosceles right triangle. The four separate cover plates 2 are spliced ​​together to form a combined cover plate. The enclosure is fixed to the inner wall of the orifice, and the combined cover plate covers the orifice. Both the enclosure panels 1 and the separate cover plates 2 are made of a hard material with strong deformation resistance, such as stainless steel.

[0021] The splicing side of the cover plate 2 is provided with a buckle 5 and a pin 7 respectively. One end of the buckle 5 is vertically rotatably connected to the cover plate 2, and the other end of the buckle 5 is provided with a locking slot 6 for the pin 7 to pass through. The pin 7 is "T" shaped. The lower end of the pin 7 is rotatably connected to the cover plate 2. After the pin 7 is rotated until its upper end coincides with the locking slot 6, the locking slot 6 allows the pin 7 to pass through from top to bottom. Then, the pin 7 is rotated to make its horizontal section misalign with the locking slot 6, thereby achieving the function of locking the two adjacent cover plates 2.

[0022] Cables 4 are connected to the two vertical edges of the cover plate 2. The enclosure plate 1 has two through holes 8. The two cables 4 on the cover plate 2 pass through one of the through holes 8 from the inside of the enclosure and are then movably connected to the outside of the enclosure (i.e., the back of the enclosure plate 1). Figure 3 As shown; the connection method is to tie a knot, or to tie a knot at the end of the cable 4 and connect the hooks by hooking them together.

[0023] The enclosure panels 1 are joined together using mortise and tenon joints. The cover panels 2 are connected to the enclosure panels 1 using hinges 3, and are further reinforced with cables 4. The cables 4, in conjunction with the hinges 3, limit the opening angle between the cover panels 2 and the enclosure panels 1 to no more than 90°. The fixed length of the cables 4 ensures that the isosceles vertical triangle cover panels can still be effectively held in place even if the hinges 3 fail or malfunction. Additionally, on the back of the enclosure panels 1, when the isosceles vertical triangle cover panels 2 and the enclosure panels 1 are closed at 0°, the cover panels 2 and the enclosure panels 1 are secured. This is the basic principle. Then, four enclosure panels 1 of the same specifications are connected together, so that the four isosceles vertical triangle cover panels 2 are joined and closed, safely protecting the opening and restricting entry, achieving a double protection effect.
