Description

Technical Field

[0001] The invention belongs to the technical field of drainage devices, and in particular relates to an automatic siphon drainage device for a roof. Background Art

[0002] At present, temporary drainage used in construction is to drain to the basement or organize drainage at the construction site. The traditional drainage method has poor drainage effect. Because the construction surface is not completed, when the rainy season comes, it is easy to form water accumulation on the construction surface and unfinished roof positions. The accumulated water will damage the construction surface and there are great quality risks. Siphons are needed for drainage.

[0003] The existing automatic siphon drainage device has the following problems:

[0004] When the water depth in front of the bucket of the existing construction roof siphon drainage device is deep, it is easy to increase the load on the construction roof, posing a threat to the overall structural safety of the unfinished construction surface. When the water depth in front of the bucket is too shallow, an effective pressure difference cannot be formed, thereby failing to trigger the siphon effect, resulting in low drainage efficiency, and rainwater cannot be discharged in time, and even causing water accumulation or overflow. Therefore, it cannot meet the existing demand for the use of automatic siphon drainage devices. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a roof automatic siphon drainage device which can increase the rainwater depth in front of the bucket, enhance the siphon effect, and realize rapid discharge of rainwater while ensuring that the construction roof will not be subjected to a large load caused by rainwater accumulation.

[0006] The technical scheme adopted in this scheme is as follows: This scheme proposes an automatic siphon drainage device for a roof, including a drainage platform, a drainage bucket, a filtering type water discharge mechanism, an offset type vertical weight mechanism and a floating pressure type drainage mechanism, the drainage bucket is arranged on the upper wall of the drainage platform, the filtering type water discharge mechanism is arranged on the upper wall of the drainage platform outside the drainage bucket, the offset type vertical weight mechanism is arranged at the end of the filtering type water discharge mechanism away from the drainage platform, the floating pressure type drainage mechanism is arranged on the offset type vertical weight mechanism, the filtering type water discharge mechanism includes an intercepting mechanism and an oblique flow mechanism, the intercepting mechanism is arranged on the upper wall of the drainage platform outside the drainage bucket, the oblique flow mechanism is arranged on the bottom wall of the drainage platform, the offset type vertical weight mechanism includes a combined force mechanism and a positioning mechanism, the combined force mechanism is arranged at one end of the oblique flow mechanism away from the intercepting mechanism, the positioning mechanism is arranged on the side of the combined force mechanism close to the oblique flow mechanism, the floating pressure type drainage mechanism includes a leakage mechanism and a pressure control mechanism, the leakage mechanism is arranged on the bottom wall of the combined force mechanism, and the pressure control mechanism is arranged inside the combined force mechanism.

[0007] As a further preferred embodiment of the present invention, the interception mechanism includes an interception cylinder and a filter port, the interception cylinder is arranged on the upper wall of the drainage platform outside the drainage bucket, and multiple groups of the filter ports are arranged on the side wall of the interception cylinder; the oblique flow mechanism includes a sewage cylinder, a sewage pipe and an oblique flow pipe, the sewage cylinder is arranged on the bottom wall of the drainage platform, the sewage pipe passes through the drainage platform and is connected between the drainage bucket and the sewage cylinder, and multiple groups of the oblique flow pipes are connected and are arranged on the side wall of the sewage cylinder.

[0008] During use, when the rainy season comes, a lot of rainwater will gather inside the construction area because there is no drainage pipe installed on the roof under construction, which will increase the bearing pressure of the unfinished construction surface and is not conducive to normal construction work on the construction surface. The drainage platform drives the sewage barrel to fit with the construction surface. When the rainwater on the construction surface exceeds the drainage bucket, the rainwater mixes with the mud and sand on the construction surface to form sewage. The sewage contains a large amount of impurities and particulate matter, which will block the pipe or affect the siphon effect. Therefore, the rainwater on the construction surface enters the sewage barrel after being filtered through the filter port, and the sewage barrel diverts the rainwater to the inclined flow pipe for discharge.

[0009] Preferably, the combined force mechanism includes a sewage tank, a combined force frame, a pipe groove, a horizontal water pipe and a drain valve. The sewage tank is connected to the side of the oblique flow pipe away from the sewage barrel, the combined force frame is arranged between adjacent sewage tanks, the pipe groove is arranged on the inner wall of the combined force frame, the pipe groove is arranged in a through-going manner, the horizontal water pipe passes through the combined force frame and is connected to the sewage tanks, the horizontal water pipe is arranged inside the pipe groove, and the drain valve is connected to the bottom wall of the sewage tank; the positioning mechanism includes a fixing block and a fixing screw, the fixing block is symmetrically arranged on the side of the sewage tank close to the oblique flow pipe, and the fixing screws are symmetrically arranged on the side wall of the fixing block.

[0010] When in use, the sewage tank is fixed to the wall below the drainage bucket by fixing screws, the sewage tank is hung on the side wall of the wall, and the oblique flow pipe is connected to the upper wall of the sewage tank. When a separate sewage tank is hung on the surface of the wall, an outward tilting force will be generated, which is not consistent with the vertical bearing capacity of the wall. After water is stored in the sewage tank, the weight increases, increasing the external hanging pressure on the wall. At this time, the sewage tanks are connected in series through the combined force frame, and the sewage tanks are pulled by each other through the combined force frame to stabilize the center of gravity of the sewage tank, so that the downward gravity of the sewage tank is consistent with the vertical bearing capacity of the wall. The vertical bearing capacity of the wall is large relative to the external hanging bearing capacity of the wall. Therefore, the vertical bearing capacity of the sewage tank and the wall is kept consistent by the combined force, and most of the weight can be concentrated on the wall with good bearing performance, thereby reducing the external hanging pressure on the wall and the load pressure on the construction surface, and then under the condition of reducing the load on the construction surface, the water depth in front of the bucket is increased, the siphon effect is enhanced, and the sewage on the construction surface can be quickly removed to ensure the normal progress of the construction work.

[0011] Specifically, the water leakage mechanism includes a water leakage cylinder and a water leakage port, the water leakage cylinder is symmetrically arranged on the bottom wall of the sewage tank, the water leakage cylinder is threadedly connected to the water leakage port, and the water leakage port is arranged on the bottom wall of the water leakage cylinder; the pressure control mechanism includes a semi-cylinder, a guide column, a buoyancy column, a pressure-stabilizing magnet, a fixed magnet and a pressure-stabilizing spring, the semi-cylinder is symmetrically arranged on the upper wall of the sewage tank on both sides of the inclined flow tube, the semi-cylinder is connected to the sewage tank, the guide column is arranged between the top wall of the semi-cylinder and the bottom wall of the water leakage cylinder, the buoyancy column is slidably arranged on the outside of the guide column, the pressure-stabilizing magnet is arranged on the bottom wall of the buoyancy column outside the guide column, the fixed magnet is arranged on the bottom wall of the water leakage cylinder outside the guide column, the pressure-stabilizing magnet and the fixed magnet are arranged opposite to each other, and the pressure-stabilizing spring is arranged between the buoyancy column outside the guide column and the top wall of the semi-cylinder.

[0012] When in use, in the initial state, the pressure-stabilizing spring is in an extended setting, the diameter of the buoyancy column is larger than the diameter of the connecting part between the leaking barrel and the sewage tank, the fixed magnet attracts the pressure-stabilizing magnet through magnetic force, and the oblique flow pipe continuously transports rainwater on the construction working surface to the inside of the sewage tank. The upper wall of the buoyancy column maintains a small distance from the upper wall of the sewage tank, the rainwater level entering the sewage tank rises, the area of ​​the buoyancy column immersed in the rainwater increases, and the buoyancy of the buoyancy column increases. As the rainwater level inside the sewage tank continues to rise, the buoyancy of the buoyancy column is greater than the adsorption magnetic force of the fixed magnet and the pressure-stabilizing magnet. The buoyancy column uses the deformation of the pressure-stabilizing spring to slide along the guide column into the interior of the semi-cylinder, the leaking barrel is connected to the sewage tank, and the external siphon is connected to the leaking port. When the water depth inside the sewage tank reaches a certain level, a siphon effect is formed, so that the rainwater is sucked into the external siphon and discharged at a higher flow rate, thereby completing the rainwater removal operation on the construction working surface.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, this solution adopts a combination of a combined force external hanging structure and a water storage structure in front of the bucket. Through the provision of a filtering type water discharge mechanism, an offset type vertical weight mechanism and a floating pressure type drainage mechanism, the interception mechanism, the oblique flow mechanism, the combined force mechanism, the positioning mechanism, the leakage mechanism and the pressure control mechanism cooperate with each other, which can not only reduce the load from rainwater on the construction surface, but also increase the water depth in front of the bucket and enhance the siphon effect. At the same time, it can filter the sewage formed by the mixture of rainwater and the construction surface, ensuring the siphon drainage pipe The passage is unobstructed, ensuring the normal construction of the construction surface. The buoyancy of the buoyancy column increases. With the continuous rise of the rainwater level inside the sewage tank, the buoyancy of the buoyancy column is greater than the adsorption magnetic force of the fixed magnet and the voltage-stabilizing magnet. The buoyancy column uses the deformation of the voltage-stabilizing spring to slide along the guide column into the interior of the semi-cylinder. The leakage cylinder is connected to the sewage tank, and the external siphon is connected to the leakage port. When the water depth inside the sewage tank reaches a certain level, a siphon effect is formed, so that the rainwater is sucked into the external siphon at a higher flow rate and discharged.

The sewage tank 13 is connected to the side of the inclined flow pipe 10 away from the sewage barrel 8. The combined force frame 14 is arranged between adjacent sewage tanks 13. The pipe groove 15 is arranged on the inner wall of the combined force frame 14. The pipe groove 15 is through-arranged. The horizontal water pipe 16 passes through the combined force frame 14 and is connected to the sewage tanks 13. The horizontal water pipe 16 is arranged inside the pipe groove 15.

[0033] The water leakage mechanism 21 includes a water leakage cylinder 22 and a water leakage port 23.

[0034] When the rainy season comes, because there is no drainage pipe installed on the roof under construction, a lot of rainwater will gather inside the construction area, increasing the load-bearing pressure of the unfinished work surface and being detrimental to normal construction work on the construction work surface;

[0035] The drainage platform 1 is placed on the construction work surface, and the drainage platform 1 drives the sewage barrel 8 to fit with the construction work surface. When the rainwater on the construction work surface covers the drainage bucket 2, the rainwater is mixed with the mud and sand on the construction work surface to form sewage. The sewage contains a large amount of impurities and particles, which will block the pipe or affect the siphon effect. Therefore, the rainwater on the construction work surface enters the sewage barrel 8 after being filtered by the filter port 6. The sewage barrel 8 diverts the rainwater to the inclined flow pipe 10 for discharge;

[0036] The sewage tank 13 is fixed to the wall below the drainage bucket 2 by fixing screws 19. The sewage tank 13 is hung on the side wall of the wall. The oblique flow pipe 10 is connected to the upper wall of the sewage tank 13. When a separate sewage tank 13 is hung on the surface of the wall, an outward tilting force will be generated, which is not consistent with the vertical bearing force of the wall. The weight of the sewage tank 13 increases after the water is stored, which increases the external hanging pressure on the wall. At this time, the sewage tanks 13 are connected in series through the combined force frame 14. The sewage tanks 13 are pulled by each other through the combined force frame 14 to stabilize the center of gravity of the sewage tank 13, so that the downward gravity of the sewage tank 13 is consistent with the vertical bearing force of the wall. The vertical bearing force of the wall is larger than the external hanging bearing force of the wall;

[0037] Therefore, by combining forces, the vertical bearing capacity of the sewage tank 13 and the wall is kept consistent, and most of the weight can be concentrated on the wall with better bearing performance. The rainwater between the sewage tanks 13 circulates through the horizontal water pipe 16, thereby reducing the external hanging pressure on the wall and the load pressure on the construction surface. Under the condition of reducing the load on the construction surface, the water depth in front of the bucket is increased, the siphon effect is enhanced, and the sewage on the construction surface can be quickly removed to ensure the normal progress of the construction work.

[0038] In the initial state, the pressure-stabilizing spring 30 is extended, the diameter of the buoyancy column 27 is larger than the diameter of the connecting portion between the leaking cylinder 22 and the sewage tank 13, the fixed magnet 29 attracts the pressure-stabilizing magnet 28 by magnetic force, the inclined flow pipe 10 continuously transports the rainwater on the construction work surface to the inside of the sewage tank 13, the upper wall of the buoyancy column 27 and the upper wall of the sewage tank 13 maintain a small distance, the liquid level of the rainwater entering the sewage tank 13 rises, the area of ​​the buoyancy column 27 immersed in the rainwater increases, the buoyancy of the buoyancy column 27 increases, and as the liquid level of the rainwater inside the sewage tank 13 continues to rise, the buoyancy of the buoyancy column 27 is increased. The buoyancy is greater than the adsorption magnetic force of the fixed magnet 29 and the voltage-stabilizing magnet 28. The buoyancy column 27 uses the deformation of the voltage-stabilizing spring 30 to slide along the guide column 26 into the interior of the semi-cylinder 25. The leakage cylinder 22 is connected to the sewage tank 13, and the external siphon is connected to the leakage port 23. When the water depth inside the sewage tank 13 reaches a certain level, a siphon effect is formed, so that rainwater is sucked into the external siphon at a higher flow rate and discharged. With the continuous discharge of rainwater inside the sewage tank 13, rainwater on the construction work surface is continuously adsorbed into the sewage tank 13, completing the rainwater removal operation on the construction work surface.

[0039] After the rainwater on the construction work surface is cleared, the sewage tank 13 cannot be replenished with subsequent rainwater, the rainwater level inside the sewage tank 13 decreases, and the buoyancy of the buoyancy column 27 is weakened. The buoyancy column 27 blocks the connection between the leaking tube 22 and the sewage tank 13 under the deformation and reset of the pressure-stabilizing spring 30 and the magnetic adsorption of the fixed magnet 29, and cuts off the leaking tube 22 and the sewage tank 13. At this time, some rainwater is still retained in the sewage tank 13. When the rainwater is discharged next time, a small amount of rainwater on the construction work surface enters the sewage tank 13, which will trigger the buoyancy column 27 to float up, causing the external siphon to drain water. When the sewage tank 13 is no longer used, the drain valve 31 is opened to discharge the residual rainwater inside the sewage tank 13; the above operation can be repeated when it is used next time.

[0040] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
