Description

Technical Field

[0001] The invention relates to the technical field of flap doors, in particular to a free side-flip flap door with good sealing performance. Background Art

[0002] The flap gate is a one-way valve installed at the outlet of the drainage pipe on the river bank. It is mainly installed at the tail end of the drainage pipe to prevent external water from backflowing. It is made of various materials such as stainless steel, cast iron, steel, composite materials (glass fiber reinforced plastics), etc. It is suitable for water conservancy systems, municipal sewage, urban flood control and drainage, sewage treatment plants, water plants, etc. When the river tide level is higher than the outlet pipe and the pressure is greater than the pressure in the pipe, the flap gate panel will automatically close to prevent the river tide from backflowing into the drainage pipe.

[0003] The current free-flipping flap door uses a sealing ring for sealing, that is, when the door cover is closed due to the pressure of the external water body, the sealing ring will be squeezed to achieve sealing. However, the sealing ring is exposed to the outside, and the water in the drain pipe will wash open the door cover during the drainage process, which will cause an impact on the sealing ring, causing the sealing ring to easily fall off, thereby affecting the sealing effect.

[0004] Moreover, the impact force of the water is not enough when the water is just released, which will cause the door cover to swing back and forth and hit the sealing ring. The door cover will also hit the sealing ring when it is closed. As a result, the sealing ring is subjected to impact and collision for a long time, which will cause the sealing ring to expand and contract back and forth, making it more likely to fall off and reduce its service life, further affecting the sealing effect.

[0005] The current free-rolling flap door cannot filter the discharged water and the water from the external rivers, which causes the mud and sand particles to easily adhere to the sealing ring, affecting the fit with the door cover, thereby reducing the sealing effect and causing the water from the external rivers to easily flow back. For this reason, we propose a free-rolling flap door with good sealing performance. Summary of the invention

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting the outer ring, inner ring and convex ring, the door cover can drive the convex ring to rotate and squeeze the sealing ring to achieve a sealing effect. The sealing ring is located between the outer ring and the inner ring, so that when the water body rushes through the door cover during water release, the water body will impact the inner ring, avoiding the problem of impact on the sealing ring, causing the sealing ring to fall off easily, thereby affecting the sealing effect. In addition, the impact of the external river water body can be blocked by the outer ring, further improving the stability of the sealing ring;

[0028] 2. When the water is just released, the impact force of the water body is not enough, which will cause the door cover to swing back and forth and hit the sealing ring. When the door cover is closed, it will also hit the sealing ring. When hitting the sealing ring, the installation ring squeezes the buffer spring to buffer the impact, thereby preventing the sealing ring from being impacted and hit for a long time, which will cause the sealing ring to stretch and deform back and forth, making it easier to fall off and reduce its service life, further affecting the sealing effect;

[0029] 3. By setting a micro electric telescopic rod, the fixing ring can drive the buffer spring to move to the left, and then drive the sealing ring to move to the left, so as to ensure that the sealing ring fits the convex ring tightly when the elasticity of the buffer spring weakens, thereby improving the sealing performance;

[0030] 4. By setting up the internal filter assembly and the filter cover, the discharged water and the water from the external rivers can be filtered, so as to prevent the sediment particles and impurities in the water from adhering to the left side of the sealing ring, affecting the fitting effect between the convex ring and the sealing ring, thereby further improving the sealing performance.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] As mentioned in the background technology, in the prior art, the sealing ring is exposed outside. When the water in the drain pipe is drained, the water will break open the door cover, which will impact the sealing ring, causing the sealing ring to fall off easily, thus affecting the sealing effect. In addition, the impact force of the water is not enough when the water is just drained, which will cause the door cover to swing back and forth and hit the sealing ring. When the door cover is closed, it will also hit the sealing ring. As a result, the sealing ring is subjected to impact and collision for a long time, which will cause the sealing ring to stretch and deform back and forth, making it more likely to fall off and reduce its service life, further affecting the sealing effect. In addition, the current free side-flipping flap door cannot filter the discharged water and the water from the external rivers, causing the mud and sand particles to easily adhere to the sealing ring, affecting the fitting effect with the door cover, thereby reducing the sealing effect and causing the problem of water from the external rivers to easily flow back. The present invention proposes a free side-flipping flap door with good sealing performance.

[0039] Example 1

[0040] Reference Figures 1 to 5 , a free side-flipping flap door with good sealing performance, comprising a fixing tube 1;

[0041] A flange ring 2 is provided at the right end of the fixed pipe 1;

[0042] By installing bolts on the flange ring 2, the fixed pipe 1 can be connected to the discharge pipe through the flange ring 2. The left end of the fixed pipe 1 extends to the river channel. The water in the discharge pipe enters the fixed pipe 1 and impacts the door cover 5, so that the water can be discharged into the river.

[0043] A mounting frame 3 is provided on the rear side of the fixed pipe 1;

[0044] The mounting frame 3 is connected to a rotating shaft 4 via a bearing;

[0045] A door cover 5 is arranged on the rotating shaft 4, and the door cover 5 can be opened by flipping sideways through the rotating shaft 4;

[0046] The left end of the fixed tube 1 is provided with an outer ring 6 and an inner ring 7;

[0047] The left ends of the outer ring 6 and the inner ring 7 are both fitted with the door cover 5;

[0048] A sealing ring 8 is fitted between the outer ring 6 and the inner ring 7;

[0049] The right end of the sealing ring 8 is provided with a mounting assembly connected to the fixing pipe 1;

[0050] The sealing ring 8 is made of rubber material;

[0051] The left side of the sealing ring 8 is fitted with a convex ring 9, and the left end of the convex ring 9 is connected to the door cover 5, so that the external water can be blocked by the sealing ring 8 and the convex ring 9, achieving a sealing effect;

[0052] In order to allow the bead 9 to rotate with the door cover 5 and leave between the outer ring 6 and the inner ring 7 , the thickness of the bead 9 needs to be smaller than the gap between the outer ring 6 and the inner ring 7 .

[0053] The sealing ring 8 is located between the outer ring 6 and the inner ring 7, so that when the water breaks through the door cover 5 during water release, the water will impact the inner ring 7, avoiding direct impact on the sealing ring 8, which will cause the sealing ring 8 to fall off easily and affect the sealing effect. The impact of external river water can be blocked by the outer ring 6, further improving the stability of the sealing ring 8.

[0054] The installation assembly includes a mounting ring 10, and the right end of the sealing ring 8 is installed on the mounting ring 10. The mounting ring 10 is fitted and connected with the outer ring 6 and the inner ring 7, and a buffer spring 11 is evenly arranged in an annular direction on the right side of the mounting ring 10. The buffer spring 11 is located between the outer ring 6 and the inner ring 7. In the prior art, the impact force of the water body is not enough when the water is just released, which will cause the door cover 5 to swing back and forth and hit the sealing ring 8, and the door cover 5 will also hit the sealing ring 8 when it is closed. In this solution, when the convex ring 9 hits the sealing ring 8, the mounting ring 10 squeezes the buffer spring 11, which can buffer the impact, thereby avoiding the sealing ring 8 from being subjected to long-term impact and impact, which will cause the sealing ring 8 to stretch and deform back and forth, make it more likely to fall off and reduce its service life, further affecting the sealing effect.

[0055] The right ends of the buffer springs 11 are connected to the fixing rings 12, and the fixing rings 12 are fitted and connected to the outer ring 6 and the inner ring 7. A micro-electric telescopic rod 13 is evenly arranged in a circumferential direction on the right side of the fixing ring 12, and the right ends of the micro-electric telescopic rods 13 are connected to the fixing tube 1. The micro-electric telescopic rod 13 enables the fixing ring 12 to drive the buffer spring 11 to move to the left, and then drive the sealing ring 8 to move to the left, thereby ensuring that the sealing ring 8 is tightly fitted to the convex ring 9 when the elasticity of the buffer spring 11 weakens, thereby improving the sealing performance.

[0056] In order to facilitate the control of the micro electric telescopic rod 13, the micro electric telescopic rod 13 is electrically connected to the backstage terminal.

[0057] An internal filter assembly is provided in the fixed pipe 1, and a filter cover 15 is provided on the outside of the fixed pipe 1. The filter cover 15 is provided on the outside of the door cover 5, and can filter the discharged water and the water from the external rivers, so as to prevent the mud and sand particles in the water from adhering to the left side of the sealing ring 8 and affecting the fitting effect of the convex ring 9 and the sealing ring 8, thereby further improving the sealing performance.

[0058] The inner filter assembly includes a filter plate 14 which is fitted and connected in a fixed pipe 1 and is used to filter the discharged water. A connecting rod 18 is evenly and circumferentially arranged on the left side of the filter plate 14. An installation sleeve 19 is slidably sleeved on the outer side of the connecting rod 18, and the installation sleeve 19 is arranged on the inner wall of the fixed pipe 1. A support spring 20 is transversely arranged in the installation sleeve 19, and the right end of the support spring 20 is connected to the left side of the connecting rod 18. When draining water, the filter plate 14 is impacted, so that the connecting rod 18 slides in the installation sleeve 19 to squeeze the support spring 20, thereby protecting the filter plate 14.

[0059] Example 2

[0060] Reference Figure 3 and Figure 5 Bearings 16 are evenly arranged on the right side of the filter plate 14, and an impeller 17 is rotatably connected to the bearing 16, so that when the water is discharged, the water impacts the impeller 17 to cause it to rotate, thereby dispersing and buffering the impact force and further protecting the filter plate 14.

[0061] The rest of the structure is the same as that of Example 1.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
