Description

Technical Field

[0001] The invention relates to a siphon type rainwater bucket which can be quickly installed in a concrete structure and an installation method thereof. Background Art

[0002] The drainage system of a building is indispensable, and the drainage of rainwater from the roof is the most important drainage system. Among them, siphon rainwater discharge uses the energy generated by the height difference between the roof and the ground. When the water on the roof reaches a certain height, the air does not enter the pipe, and negative pressure is generated when draining in a full pipe flow state (i.e. siphon state). Suction is formed in the pipe to quickly drain the rainwater. The siphon rainwater bucket is a specially designed rainwater bucket, which allows the rainwater to form a full flow state in the pipe at a very shallow gutter depth. The height of the building and the potential energy of the falling water are used to create a local vacuum in the pipe, so that the water flow in the rainwater bucket and the horizontal pipe obtains additional pressure to form a siphon phenomenon. The siphon effect is used to greatly accelerate the flow rate of water in the drain pipe and quickly discharge the roof rainwater.

[0003] At present, when pouring concrete, concrete will flow into the rain gutter, causing blockage inside the rain gutter, causing damage to the downspout tail pipe, and preventing the exposed rain gutter adjusting bolt threads from being corroded by concrete. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a siphon type rain gutter that can be quickly installed in a concrete structure and an installation method thereof. After the tail pipe is inserted into the hole opened on the template, the motor is started, and the power output end of the motor drives the rotating shaft to rotate. As the rotating shaft rotates, the connecting plate is driven to rotate toward one side, pushing the connecting rod to move in the same direction. When multiple connecting plates deflect on the same side, the connecting rod is allowed to swing up and down with the same amplitude. Under the rotation of the rotating rod, the rotating shaft drives the sealing plate to rotate, so that the multiple sealing plates are changed from a vertical state to a horizontal state, and each sealing plate is abutted against each other to seal the water inlet of the sealed connecting pipe. In this way, when concrete is poured, concrete cannot enter the rain gutter, no blockage will occur, and damage to the tail pipe is avoided. At the same time, in order to avoid the exposed rain gutter adjusting bolt threads or being corroded and damaged by concrete, the service life of the rain gutter is improved.

In this way, when concrete is poured, concrete cannot enter the rain gutter, no blockage will occur, and damage to the tail pipe is avoided. At the same time, in order to avoid the exposed rain gutter adjusting bolt threads or being corroded and damaged by concrete, the service life of the rain gutter is improved.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention. The experimental methods in the following embodiments, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following embodiments, unless otherwise specified, can be obtained from commercial channels.

[0019] Example: like Figure 1 - Figure 7 As shown, this embodiment proposes a siphon rain gutter 2 that can be quickly installed in a concrete structure, including a pre-buried base, a steel support frame 1 and a rain gutter 2. The pre-buried base is arranged in the roof water collection area through the steel support frame 1. The pre-buried base includes a mounting plate 3 arranged on the steel support frame 1. A drainage hole is opened on the surface of the mounting plate 3, and a sinking pipe 4 connected to the drainage hole is arranged on the lower surface of the mounting plate 3. The rain gutter 2 is arranged at the lowest point of the rain gutter through the sinking pipe 4. A sealing component is arranged around the opening of the drainage hole to prevent the inside of the rain gutter 2 from being blocked during concrete pouring. After inserting the tail pipe 22 into the hole opened on the template, the motor 11 is started, and the power output end of the motor 11 drives the rotating shaft 8 to rotate. As the rotating shaft 8 rotates, the connecting plate 9 is driven to rotate toward one side, pushing the connecting rod 12 to move in the same direction. When multiple connecting plates 9 deflect on the same side, the connecting rod 12 is allowed to swing up and down with the same amplitude. Under the rotation of the rotating rod 14, the rotating shaft 8 drives the sealing plate 15 to rotate, and the multiple sealing plates 15 are changed from vertical to horizontal, and each sealing plate 15 is abutted to seal the water inlet of the sealed connecting pipe 5. In this way, when pouring concrete, concrete cannot enter the rain gutter 2, and no blockage will occur, thereby avoiding damage to the tail pipe 22. At the same time, this is to avoid the exposed rain gutter 2 adjusting bolt threads or being corroded and damaged by concrete.

[0020] The sealing assembly includes a sealing connection pipe 5 arranged at the opening of the drain hole, and the sealing connection pipe 5 has a flange 6 extending outward from the top and bottom, and a limit bolt for fixing the sealing connection pipe 5 is arranged on the flange 6. A plurality of through holes are opened around the outer side of the flange 6, and the flange 6 can be fixed by passing the limit bolts through the through holes, thereby fixing the sealing connection pipe 5 on the surface of the mounting plate 3. A plurality of bearing seats 7 are arranged at equal intervals around the outer side of the sealing connection pipe 5, and a rotating shaft 8 is inserted in each of the bearing seats 7. The end of the rotating shaft 8 away from the bearing seat 7 is connected to a connecting plate 9. When the power output end of the motor 11 drives one of the rotating shafts 8 to rotate, the tail of the connecting plate 9 is driven to rotate toward one side, pushing the connecting rod 12, so that the other group of connecting plates 9 follows the tilt rotation. At this time, all the connecting rods 12 and the connecting plates 9 rotate in coordination, so that each rotating shaft 8 rotates with it, thereby driving the rotation of the sealing plate 15. A support frame 10 is provided on the outside of the sealing connection pipe 5, and a motor 11 is installed on the surface of the support frame 10. The power output end of the motor 11 extends into the support frame 10 and is connected to the connecting plate 9. The motor 11 is supported by the support frame 10 to ensure the stability of the motor 11 during operation. When the motor 11 drives one of the rotating shafts 8 to rotate, all the rotating shafts 8 can be driven to rotate. A connecting rod 12 for synchronously coordinating the driving of the rotating shaft 8 to rotate is provided between each two adjacent connecting plates 9. A fixed seat 13 is centrally provided in the sealing connection pipe 5, and a plurality of rotating rods 14 are equidistantly provided around the outer side of the fixed seat 13. A groove is provided at one end of the sealing plate 15 toward the rotating rod 14, and the rotating rod 14 is inserted into the groove. When the rotating shaft 8 rotates, the sealing plate 15 can rotate with the coordinated rotation of the rotating rod 14. The rotating shaft 8 extends to the sealing connecting pipe 5 and is connected to a sealing plate 15. The sealing plate 15 is connected to the rotating rod 14 at one end away from the rotating shaft 8. In the initial state, the sealing plates 15 are all standing relative to each other. As the rotating shaft 8 rotates, each sealing plate 15 is placed horizontally, and each sealing plate 15 abuts against each other to form a sealing layer. As a result, concrete cannot enter the rain gutter 2, and no blockage will occur, thereby avoiding damage to the tail pipe 22. At the same time, in order to avoid the exposed rain gutter 2 adjusting bolt threads or being corroded and damaged by concrete, the service life of the rain gutter 2 is improved.

[0021] Further, the rainwater bucket 2 includes a chassis 16 arranged in the sinking pipe 4, a bucket body 17 is arranged on the surface of the chassis 16, and a filter grille is arranged on the upper surface of the bucket body 17. The filter grille includes a grid plate 18 arranged around the surface of the bucket body 17, and a water inlet 19 for rainwater to flow in is reserved between each two grid plates 18. Impurities in the rainwater are filtered through the grid plates 18 to avoid clogging of the tail pipe 22. The rainwater enters the tail pipe 22 through the water inlet 19. A disk body 20 is arranged on the upper surface of the filter grille, and a plurality of guide plates 21 are arranged at equal intervals around the surface of the disk body 20. An anti-vortex device (not shown in the figure) is arranged in the bucket body 17. The lower surface of the bucket body 17 is connected to the tail pipe 22.

[0022] A method for using a siphon rainwater bucket 2 that is quickly installed in a concrete structure, the specific steps are as follows: S1. Understand the caliber and specifications of the siphon rain bucket 2 to be installed on site, and grasp the location of the rain bucket 2 in advance. After the roof formwork construction is accepted, use laser positioning to mark the installation position of the rain bucket 2 in the longitudinal direction, and mark the center point of the installation position of the rain bucket 2 in the straight line direction; S2. According to the positioning mark made in S1, a hole is mechanically opened on the template. The diameter of the hole is one specification size larger than the diameter of the tail pipe 22 of the rain gutter 2, and the tail pipe 22 is inserted into the hole; S3, calculate the installation height of the upper surface of the rain gutter 2, and fix all the steel meshes within 50 cm around the rain gutter 2 by electric spot welding; S3-2, weld a steel support frame 1 under the mounting plate 3 to hold the rain gutter 2, and firmly weld the welded steel support frame 1 to the surrounding welded steel mesh; S4, the multiple sealing plates 15 are initially perpendicular to each other, then the motor 11 is started, and the power output end of the motor 11 drives the rotating shaft 8 to rotate. As the rotating shaft 8 rotates, the connecting plate 9 is driven to rotate toward one side, pushing the connecting rod 12 to move in the same direction; S4-2, when the multiple connecting plates 9 deflect on the same side, the connecting rod 12 is allowed to swing up and down with the same amplitude, and the rotating shaft 8 drives the sealing plate 15 to rotate under the rotation of the rotating rod 14, so that the multiple sealing plates 15 are changed from vertical to horizontal, and each sealing plate 15 is abutted against each other to seal the water inlet of the sealing connecting pipe 5; S5. Before pouring concrete, use sealing tape to wrap the thread teeth with multiple layers for protection. During the concrete pouring process, vibrate the periphery of the rain gutter 2; S6. Before waterproofing the roof and making the protective layer structure, after the rain gutter 2 is tightly sealed, the roof is subjected to a 24-hour water-tightness test to check whether there is any leakage in the structure of the rain gutter 2.
