Description

Technical Field

[0001] The invention relates to the field of roof drainage, and in particular to an external siphon negative pressure water collecting device. Background Art

[0002] The old-style gutters on the roofs of old buildings are generally connected to the ground through four to six vertical pipes. They use the gravity of rainwater to drain water, with limited drainage capacity and easy to clog. Nowadays, newer buildings often use siphon rainwater buckets installed in the gutters to improve the drainage effect, but the old-style gutters cannot meet the requirements of the siphon system and the installation of siphon rainwater buckets due to their location and space size. If you choose to build a new external gutter outside the old building, the cost is too high, and the cost and energy loss are large. Summary of the invention

[0003] The purpose of the present invention is to provide an external siphon negative pressure water collection device, which uses a siphon rainwater bucket to improve the drainage effect of old buildings on the basis of appropriate cost.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an external siphon negative pressure water collection device is arranged on the outside of the old-style gutter of the building, comprising a tank body and a siphon rainwater gutter; the siphon rainwater gutter is arranged at the bottom of the tank body, and its water suction port is located inside the tank body, and the water outlet is located outside the tank body, and the water outlet is connected to the siphon water pipe arranged on the outside of the building through a water pipe; a breathing valve is arranged on the top of the tank body, and the upper end of the side wall is connected to the old-style gutter through a water pipe.

[0005] Preferably, a plurality of groups of external siphon negative pressure water collection devices are arranged on the outside of the old-style gutter.

[0006] Preferably, a plurality of groups of the external siphon negative pressure water collection devices and a group of the siphon water pipes are provided on opposite sides of the building.

[0007] Preferably, multiple groups of the external siphon negative pressure water collection devices located on the same side of the building share a group of siphon water pipes, and the siphon water pipes include interconnected siphon transverse pipes and siphon vertical pipes, and each of the siphon rainwater buckets is connected to the siphon transverse pipe through a water pipe.

[0008] Preferably, a support frame is provided on the outer side of the old-style gutter, and the support frame is used to install the tank body and hoist the siphon cross pipe.

[0009] Preferably, a T-shaped air vent is provided on the top of the tank body, and the breathing valve is installed inside the air vent.

[0010] Preferably, a support frame is provided on the outer side of the old-style gutter, and the support frame is used to install the tank body.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: by designing an external siphon negative pressure water collection device, the present invention enables old gutters that cannot be equipped with siphon rainwater buckets to also perform siphon drainage, thereby improving the drainage effect of the building; at the same time, it eliminates the high-cost external gutters, simplifies the renovation plan of old buildings, and facilitates the maintenance of old buildings.

[0014] Figure 3 yes Figure 2 A schematic diagram of one side of a drainage device;

[0015] Figure 4 yes Figure 3 Enlarged schematic diagram of part A DETAILED DESCRIPTION

[0016] The embodiment of the present invention discloses an external siphon negative pressure water collection device, which is arranged outside the old-style gutter of the building. Figure 1 As shown, a set of external siphon negative pressure water collection devices includes a tank body 1 and a siphon rainwater bucket. The siphon rainwater bucket adopts a conventional structure in the industry. The present invention does not make any requirements on its structure, and this part of the structure is hidden in the figure.

[0017] The upper end of the side wall of the tank body 1 is connected to a water pipe 2, and the other end of the water pipe 2 is connected to the old gutter to receive rainwater and transmit it to the inside of the tank body 1. The outer edge of the siphon rainwater bucket is welded to the bottom of the tank body 1, and its water inlet is located inside the tank body 1, and the water outlet is located outside the tank body 1, and the water outlet is connected to the water pipe 3. A T-shaped air permeable pipe 4 is fixed on the top of the tank body 1, and a breathing valve is installed inside the air permeable pipe 4, and the breathing valve has a one-way air permeability effect.

[0018] When water enters the tank body 1, the air in the tank body 1 will be discharged from the ventilation pipe 4. When the water accumulates to a certain extent, a negative pressure state is formed in the tank body 1, so that the siphon rainwater bucket works, thereby accelerating the discharge of rainwater.

[0019] Figures 2 to 4 The figure shows a situation where an external siphon negative pressure water collection device is actually applied to a building 8, where support frames 7 are provided on both the east and west sides of the building 8, and each set of support frames 7 is provided with a set of drainage devices, which includes four sets of external siphon negative pressure water collection devices and a set of siphon water pipes.

[0020] For the building 8, multiple sets of external siphon negative pressure water collection devices are arranged on two opposite sides thereof, which can symmetrically improve the drainage effect on both sides of the building, and the multiple sets of external siphon negative pressure water collection devices located on the same side of the building only require one set of siphon water pipes.

[0021] The siphon water pipes are correspondingly arranged outside the building and below the external siphon negative pressure water collection device. A set of siphon water pipes includes a siphon horizontal pipe 5 and a siphon vertical pipe 6 that are connected. The external siphon negative pressure water collection device is fixed in the frame of the support frame 7 at equal intervals. At the same time, the support frame 7 can also hoist the siphon horizontal pipe 5, eliminating the operation of fixing the siphon horizontal pipe 5 on the outer wall of the building 8.

[0022] See also Figure 4 The siphon rainwater bucket in each set of external siphon negative pressure water collection device can be connected to the siphon horizontal pipe 5 through a short water connection pipe 3, thereby guiding the rainwater to the siphon vertical pipe 6 through the siphon horizontal pipe 5, and then draining to the ground. The drainage efficiency can be greatly improved through a set of siphon water pipes, which improves the problem of needing multiple vertical pipes arranged at equal intervals to achieve drainage.

[0023] In summary, the present invention designs an external siphon negative pressure water collection device, so that old gutters that cannot be installed with siphon rainwater buckets can also perform siphon drainage, thereby improving the drainage effect of the building; at the same time, it eliminates the high cost of external gutters, simplifies the renovation plan of old buildings, and facilitates the maintenance of old buildings.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
