Description

Technical Field

[0001] The invention belongs to the field of gate sealing devices, and in particular relates to a gate sealing mechanism with a leak-proof effect. Background Art

[0002] The cross section of the current water outlet gate is square, and a gate is arranged on one side of the water outlet gate, and the gate is lifted and lowered by a lifting rod above the gate.

[0003] When the gate is driven to move upward, the outlet gate opens and water can be released smoothly. When the gate is driven to move downward, the outlet gate is completely covered and closed, so that water can be blocked smoothly.

[0004] And as Figure 7 As shown, the existing water outlet is located in concrete. The water outlet formed by the concrete has two problems. One is the flatness defect of the concrete wall itself. If the flatness is not good, the fit with the gate is not good. If the fit is not good, the following will be formed: Figure 8 The leakage shown, the curved part represents the leakage direction. Once the concrete is washed away, the hole becomes larger and larger. Secondly, when water enters from the fitting part, there is no other obstacle and it will directly reach the opening of the water outlet. Even if a rubber strip is placed, the rubber strip will age. Once aged, the leakage will become more serious. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a gate sealing mechanism with a leak-proof effect to solve the problem that the existing water outlet gate has a single structure, is made of concrete, cooperates with the gate, and is prone to leakage over a long period of time.

[0006] The present invention is achieved through the following technical solutions.

[0007] A gate sealing mechanism with a leak-proof effect comprises a gate, a lifting rod is connected to the top of the gate, the lifting rod can control the gate to rise and fall, a concrete wall is arranged on one side of the gate, a water outlet is opened on the concrete wall, an embedded frame is arranged in the concrete wall, the embedded frame comprises an embedded frame body, the embedded frame body is a hollow rectangular thin-walled part, the outside of the embedded frame body is provided with a flange, a first water stop ring and a second water stop ring, the embedded frame body is fitted at the water outlet, and the first water stop ring and the second water stop ring enter into the concrete wall, the flange is arranged on one side of the concrete wall, and is located between the concrete wall and the gate. By adding the embedded frame, the fit with the gate can be effectively changed, so that the probability of leakage is reduced, and the addition of two water stop rings greatly enhances the waterproof effect.

[0008] Preferably, a soft rubber material is provided on one side of the gate to achieve surface matching through a soft water-stopping method.

[0009] Preferably, the length of the embedded frame is greater than the thickness of the concrete wall by more than 400 mm.

[0010] Preferably, the height of the first water stop ring and the second water stop ring is greater than or equal to 100 mm. If it is too low, it is easy to be bypassed by leaking water.

[0011] Preferably, a gate valve is arranged outside the gate, the gate valve and the gate outer frame are consistent in size, and can be sealed with fasteners and soft rubber materials.

[0012] Compared with the existing technology: two problems are solved by adding an embedded frame. One is the problem of plane fit. Standard parts have better fit than concrete, and the sides are not prone to corrosion and leakage. The other is that the two protective water-stop rings can prevent further leakage of the water body. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] A gate sealing mechanism with a leak-proof effect comprises a gate 3, a lifting rod 4 is connected to the top of the gate 3, and the lifting rod 4 can control the gate 3 to rise and fall, a concrete wall 5 is arranged on one side of the gate 3, and a water outlet is opened on the concrete wall 5, characterized in that an embedded frame 1 is arranged in the concrete wall 5, and the embedded frame 1 comprises an embedded frame body, and the embedded frame body is a hollow rectangular thin-walled part, and a flange 13, a first water stop ring 12 and a second water stop ring 11 are arranged on the outside of the embedded frame body, and the embedded frame body is attached to the water outlet, and the first water stop ring 12 and the second water stop ring 11 are attached to the first water stop ring 11. A water stop ring 12 and a second water stop ring 11 enter into the concrete wall 5, the flange 13 is arranged on one side of the concrete wall 5 and between the concrete wall 5 and the gate 3, a soft rubber material is also arranged on one side of the gate 3, the embedded frame 1 is an integrally formed stainless steel part, the length of the embedded frame 1 is greater than 400mm of the thickness of the concrete wall 5, the height of the first water stop ring 12 and the second water stop ring 11 is greater than or equal to 100mm, a gate valve is arranged outside the gate 3, the gate valve and the gate outer frame are of the same size, and can be sealed with fasteners and soft rubber materials.

[0022] When the lifting rod 4 drives the gate 3 to move upward, the water outlet gate is opened and water can be released smoothly. When the lifting rod 4 drives the gate 3 to move downward, the water outlet gate is completely covered and closed, which can smoothly block water.

[0023] When the water outlet is blocked, the embedded frame is added in this application, so even if there is leakage, such as Figure 4 As shown, the flange 13 is arranged on one side of the concrete wall 5 and is located between the concrete wall 5 and the gate 3. Therefore, as shown by the curve in the leakage direction diagram, the water enters from the fitting part between the soft rubber material and the flange 13. Since the flange 13 is a stainless steel body, the precision is controlled during production, so the veneer effect is good, and the gap after veneer is very small, so the probability of leakage can be effectively reduced.

[0024] Assuming that water really enters from the fitting part, the water will not flow directly into the water outlet after flowing in, but will flow along the outer side of the flange 13 into the concrete wall 5, and continue to flow under the action of water pressure, reaching the positions of the first water stop ring 12 and the second water stop ring 11 in turn. The first water stop ring 12 and the second water stop ring 11 form a secondary protection function, which can effectively prevent further leakage of water.

[0025] The sealing form of gate 3 is rubber sealing to ensure no leakage at the corners; it is fixed to the gate body with stainless steel bolts and pressure plates, and the seal can be replaced by taking out the door body. The seal form can be flexibly adopted as a four-sided P-type or a tooth-type plus flat plate structure according to on-site use.

[0026] In order to facilitate installation and later maintenance, and to ensure good sealing between the outer frame of the gate valve and the concrete wall 5, the gate valve manufacturer should design a 304 stainless steel embedded frame 1 according to its own product size and civil engineering structure drawings. The length is greater than the thickness of the concrete wall 5 by 400mm. Two annular water stop rings are set in the middle of one side embedded in the concrete wall 5. The height of the water stop ring is not less than 100mm, which is consistent with the size of the gate valve connection part and the gate valve outer frame, and can be sealed with fasteners and soft rubber materials. The other side is turned over and fits tightly with the concrete wall 5. The material of the entire embedded frame is consistent with that of the gate valve outer frame. The structure and material thickness of each part are calculated by the manufacturer. It is required to have sufficient structural strength after installation to withstand concrete vibration operations and no deformation and shaking under various long-term use conditions.

[0027] While the gate 3 ensures good leakage-stopping effect (leakage ≤ 0.1 L / min·m), the gate valve is designed with a rubber wear compensation mechanism, through which the gate valve can still have reliable sealing performance after long-term use.

[0028] According to the distance from the gate installation position to the drive device installation position, a corresponding length of hanger must be used and the shaft guide frame must be used according to the actual situation.

[0029] The gate body adopts a plane reinforced welded structure, which makes the gate structure light while ensuring that the gate body has sufficient rigidity and high performance. Under the highest water head, its bending deflection is no more than 1 / 800.

[0030] The gate frame is made of bent steel plates with a guide groove structure. It can be reinforced appropriately according to actual conditions. If there is a water seal seat plate in the door frame, it must be polished to ensure that the water seal is evenly fitted.

[0031] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
