Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage channels, and in particular to a rainwater collection drainage channel for embedded steel structure factory buildings. Background Technology
[0002] Rainwater collection and diversion channels are facilities used to collect and guide rainwater. On the roof of a steel structure factory building, in order to prevent rainwater from accumulating and to facilitate the collection and drainage of rainwater, corresponding grooves need to be opened on the roof plate for the diversion channels to be embedded and installed.
[0003] While existing rainwater collection channels are equipped with rainwater grates on top to intercept larger impurities, other problems exist during use. For example, the positioning of the grates is poor; the grates rely on their own weight to press directly onto the channel frame. If someone on the roof accidentally kicks or bumps the grates, they can shift and separate from the channel frame, requiring manual repositioning. This results in poor stability. Furthermore, it is inconvenient to disassemble and assemble the internal filter plates. The grates intercept larger impurities, while the internal filter plates intercept smaller ones. When cleaning or replacing the filter plates, tools are needed to remove the screws securing them, reducing maintenance efficiency. To address these issues, we propose an embedded steel structure rainwater collection channel for factory buildings. Utility Model Content
[0004] The purpose of this utility model is to provide an embedded steel structure factory rainwater collection and diversion channel, which solves the problems of poor positioning effect of existing diversion channels for grates and inconvenience for quick disassembly and assembly of internal filter plates.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an embedded steel structure factory rainwater collection and diversion channel, including a channel frame, a grate placed on the top of the channel frame, a connecting pipe penetrating through the bottom of the channel frame, a fixing seat installed inside the channel frame, a rod welded to the grate inside the fixing seat, a first magnetic block embedded inside the fixing seat, a second magnetic block magnetically connected to the first magnetic block installed at the bottom of the rod, a metal filter plate placed inside the channel frame, a locking seat bolted to the channel frame on both the front and back of the metal filter plate, a positioning plate on the top of the metal filter plate, and a limit spring bolted between the top of the positioning plate and the grate by a spring fixing piece.
[0006] The above technical solution can improve the positioning effect of the rainwater grate, prevent accidental displacement caused by personnel, increase the pressure resistance of the top, and provide good stability and protection. At the same time, it can facilitate quick disassembly and assembly of the internal filter plate, making the operation simple and convenient, improving the maintenance efficiency of personnel, and making it highly practical.
[0007] The present invention is further configured such that: a positioning frame is installed at the bottom of the grate, and a sealing ring that is bonded to the grate is fitted on the surface of the positioning frame.
[0008] By adopting the above technical solution, the sealing effect between the bottom of the grate and the groove frame can be improved by setting the positioning frame and the sealing ring.
[0009] The present invention is further configured such that a valve is installed on the surface of the connecting pipe.
[0010] By adopting the above technical solution, the opening and closing of the connecting pipe can be controlled through the setting of valves, making it convenient for personnel to discharge the rainwater collected in the trough frame to the outside.
[0011] The present invention is further configured such that: telescopic rods are symmetrically installed between the top of the positioning plate and the grate.
[0012] By adopting the above technical solution, the positioning plate can be limited by the telescopic rod, preventing it from tilting when it is pressed upward.
[0013] The present invention is further configured such that the surfaces of the groove frame and the grate are coated with anti-corrosion coating.
[0014] By adopting the above technical solution and applying anti-corrosion coating, the anti-corrosion and moisture-proof effects of the trough frame and grate surface can be improved.
[0015] The present invention is further configured such that the limiting spring is made of carbon spring steel.
[0016] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. This utility model uses screws to embed the trough frame into a reserved groove on the top of the factory building. After the trough frame is fixed, the grate is lifted horizontally and placed above the trough frame. Then, the grate is lowered so that the insertion rod is placed in the first magnetic block inside the trough frame. Then, the grate is lowered to the bottom and fits against the top of the trough frame. After the grate is lowered to the bottom, the second magnetic block at the bottom of the insertion rod will magnetically attract the first magnetic block. This can improve the positioning effect of the rain grate, prevent personnel from accidentally touching it and causing displacement, and also increase the pressure resistance of the top, with good stability and protection.
[0019] 2. This utility model allows for quick and easy cleaning of the metal filter plates by simply opening the grate, removing the grate, grasping the metal filter plate and pulling it upwards, inserting a new metal filter plate between the two retainers, and finally replacing the grate. The replacement of the grate causes the positioning plate to contact the metal filter plate and move inwards. As the positioning plate moves, it compresses the limit spring, causing it to contract. The contracted limit spring pushes the positioning plate to press firmly against the metal filter plate. This facilitates quick and easy disassembly and assembly of the internal filter plates, making the operation simple and convenient, improving maintenance efficiency, and demonstrating high practicality.

To clean the metal filter plate 8, simply open the grate 2, remove it, and pull the metal filter plate 8 upwards. Then, insert a new metal filter plate 8 between the two mounting brackets 9. Finally, close the grate 2 again. When the grate 2 is closed, the positioning plate 10 contacts the metal filter plate 8 and moves inwards. As the positioning plate 10 moves, it compresses the limit spring 11, causing it to contract. The contraction of the limit spring 11 pushes the positioning plate 10 to press firmly against the metal filter plate 8. This facilitates quick and easy disassembly and assembly of the internal filter plates, making operation simple and convenient, improving maintenance efficiency, and demonstrating high practicality.
[0036] refer to Figure 6 Telescopic rods 15 are symmetrically installed between the top of the positioning plate 10 and the grate 2. The telescopic rods 15 can limit the positioning plate 10 and prevent it from tilting when it is pressed upward.
[0037] refer to Figure 6 The limit spring 11 is made of carbon spring steel and has excellent mechanical properties, good spring damping performance, low temperature resistance and corrosion resistance.
[0038] The spring retaining plates at both ends of the limit spring 11 are directly fixed with screws. When the limit spring 11 is damaged or its performance deteriorates, the screws can be removed with tools and replaced.
[0039] Brief description of the usage process: When cleaning the metal filter plate 8, simply open the grate 2. After removing the grate 2, directly grasp the metal filter plate 8 and pull it upwards. Then, insert the new metal filter plate 8 between the two retainers 9. Finally, put the grate 2 back on. After the grate 2 is put on, the positioning plate 10 will contact the metal filter plate 8 and move inwards. When the positioning plate 10 moves, it will press the limiting spring 11 to retract. When the limiting spring 11 retracts, it will push the positioning plate 10 to press the metal filter plate 8 tightly.
