Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering, and in particular to an L-shaped water seal structure for a planar gate. Background Technology

[0002] Flat steel gates are an important component of hydraulic structures in water conservancy and hydropower projects, and water seal devices are a crucial part of flat steel gates. L-shaped water seals are commonly used on exposed flat gates. Utilizing the pre-existing compression allowance and water pressure during installation, the L-shaped rubber water seal adheres tightly to the gate slot's water-stop surface. The greater the water pressure, the closer the water seal adheres, resulting in a better sealing effect.

[0003] One type of L-type water seal is the inner R right-angle L-type water seal (such as...). Figure 1 and Figure 2 As shown, the inner R right-angle L-shaped water seal achieves its sealing effect by having its entire surface tightly adhered to the water-stopping surface of the door groove. The inner R right-angle L-shaped water seal is a common type that uses a flat plate as the water seal pad and another flat plate as the water seal pressure plate, connected by bolts.

[0004] Currently, in practical engineering applications, the following problems have been found with the inner R right-angle L-shaped water seal:

[0005] In the relationship between the gate and the gate slot, the free end of the L-shaped water seal is relatively close to the tip of the steel plate of the gate slot embedded part. Because the planar gate will sway in a relatively horizontal direction during the opening and closing process, the water seal of the gate using the traditional inner R right-angle L-shaped water seal arrangement may be cut or torn by the corner tip of the steel plate of the gate slot embedded part. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an L-shaped water seal structure for a planar gate, in view of the above-mentioned problems.

[0007] The technical solution adopted by this utility model is: an L-shaped water seal structure for a planar gate, characterized in that it includes a water seal pad, an L-shaped water seal, and a water seal pressure plate. The water seal pressure plate is connected to the gate leaf panel of the planar gate. The water seal pad, the L-shaped water seal, and the water seal pressure plate are connected by bolts, so that when the planar gate is closed, the L-shaped water seal can abut against the water-stopping surface of the first gate slot.

[0008] The water seal pressure plate includes a first connecting part, an extension part, and a second connecting part. The first connecting part is connected to the L-shaped water seal via the bolt. The second connecting part is connected to the door leaf panel. The first connecting part and the second connecting part are connected via the extension part. The extension part is used to adjust the distance between the L-shaped water seal and the door leaf panel so that the L-shaped water seal can maintain a certain distance from the tip of the first door groove.

[0009] By using the above-mentioned technical means, the distance between the L-shaped water seal and the gate leaf panel is adjusted by the extension of the water seal pressure plate, so that the L-shaped water seal and the tip of the first gate slot are kept at a certain distance, thereby preventing the L-shaped water seal from colliding with the tip of the first gate slot during the movement of the gate.

[0010] In some embodiments, the distance between the L-shaped water seal and the tip of the first gate slot is L, and the shortest distance between the side block on the planar gate and the first gate slot is the first gap. The length of L can be determined based on the first gap.

[0011] In some embodiments, the width of the water-stopping surface of the first door groove is W, and the size of the L-shaped water seal can be determined based on the first gap and W.

[0012] In some embodiments, the distance between the extension and the first gate groove waterstop surface is H, and the distance between the side wheel on the planar gate and the second gate groove is the second gap. The length of H can be determined based on the second gap.

[0013] In some embodiments, the water seal plate is in the shape of an "I".

[0014] The beneficial effects of this utility model are:

[0015] 1. The L-shaped water seal is connected through the first connecting part and the gate leaf panel is connected through the second connecting part. The first connecting part and the second connecting part are connected by the extension part, and the distance between the L-shaped water seal and the gate leaf panel is adjusted by the extension part so that the L-shaped water seal is removed from the depth range of the gate groove, so as to avoid the L-shaped water seal from contacting the tip of the first gate groove and prevent the L-shaped water seal from being cut or torn by the tip of the first gate groove during the operation of the gate.

[0016] 2. Compared to the traditional water seal structure that requires bolts to pass through the gate leaf panel and two people to work on both sides of the gate leaf panel, this structure is only connected to one side of the gate leaf panel, which helps to improve the installation convenience of the planar gate water seal structure.

[0026] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0027] Combination Figures 1 to 2 As shown, the planar gate 1 adopts a traditional arrangement of an inner R-shaped right-angled L-shaped water seal structure 3. The first side of the planar gate 1 has a first gate slot 7, and the second side has a second gate slot 8. The first side of the planar gate 1 has a side stop 9 facing the first gate slot 7, and the second side has a side wheel 2. The side stop 9 and the side wheel 2 are used to limit the amplitude of the planar gate 1's swaying. The gate leaf panel of the planar gate 1 has an inner R-shaped right-angled L-shaped water seal structure 3, which abuts against the water-stopping surface of the first gate slot 7.

[0028] like Figure 3As shown, this embodiment is an L-shaped water seal structure for a planar gate, including a water seal pad 5, an L-shaped water seal 6, and a water seal pressure plate 4. The water seal pressure plate 4 is connected to the gate leaf panel of the planar gate 1. The water seal pad 5, the L-shaped water seal 6, and the water seal pressure plate 4 are connected by bolts, so that when the planar gate 1 is closed, the L-shaped water seal 6 can abut against the water-stopping surface of the first gate slot 7. Specifically, the water seal pressure plate 4 includes a first connecting part, an extension part, and a second connecting part. The first connecting part is connected to the L-shaped water seal 6 by bolts, the second connecting part is connected to the gate leaf panel, and the first connecting part and the second connecting part are connected by the extension part. The extension part is used to adjust the distance between the L-shaped water seal 6 and the gate leaf panel, so that the L-shaped water seal 6 can maintain a certain distance from the tip of the first gate slot 7.

[0029] Furthermore, the first connecting part, the extension part, and the second connecting part of the water seal pressure plate 4 are connected in an "I" shaped structure.

[0030] Furthermore, such as Figure 1 As shown, the shortest distance between the upper stop block 9 of the planar gate 1 and the first gate slot 7 is the first gap, and the distance between the upper wheel 2 of the planar gate 1 and the second gate slot 8 is the second gap. Figure 3 As shown, the distance between the L-shaped water seal 6 and the tip of the first gate slot 7 is L. The length of L can be determined based on the first gap. Specifically, since the first gap determines the maximum sway of the planar gate 1 in the direction of water flow, the length L is controlled to prevent the L-shaped water seal 6 from being damaged by the sharp corner of the first gate slot 7 during the back-and-forth swaying of the planar gate 1. The distance between the extension and the water-stopping surface of the first gate slot 7 is H. The distance between the side wheel 2 on the planar gate 1 and the second gate slot 8 is the second gap. The length H can be determined based on the second gap. Specifically, since the second gap determines the maximum sway of the planar gate 1 in the direction perpendicular to water flow, the length H is controlled to prevent the water seal pressure plate 4 from colliding with the embedded part of the first gate slot 7 during the left-right swaying of the planar gate 1, thereby avoiding damage to the water seal pressure plate 4.

[0031] Furthermore, the width of the water-stopping surface of the first gate slot 7 is W. Based on the first gap and W, the size of the L-shaped water seal 6 can be determined. Specifically, the width W of the water-stopping surface of the first gate slot 7 and the first gap must be considered comprehensively to prevent the L-shaped water seal 6 from exceeding the water-stopping surface of the first gate slot 7 during the shaking of the planar gate 1, which would cause the L-shaped water seal 6 to be damaged by the concrete surface.

[0032] Unlike traditional pressure plate types, this water seal structure uses an "I"-shaped water seal pressure plate 4. The distance between the L-shaped water seal 6 and the gate leaf panel is adjusted via an extension, allowing the L-shaped water seal 6 to be displaced from the depth range of the first gate slot 7. This prevents the L-shaped water seal 6 from contacting the tip of the embedded steel plate in the first gate slot 7, thus preventing the L-shaped water seal 6 from being cut or torn by the steel plate tip. Based on the first gap, the second gap, and the width W of the water-stopping surface of the first gate slot 7, the lengths L and H are comprehensively controlled to ensure that this water seal structure has sufficient freedom to prevent the L-shaped water seal 6 from being cut or torn by the tip of the embedded steel plate in the gate slot during the operation of the planar gate 1.

[0033] Meanwhile, traditional water seal structures use bolts to pass through the door leaf panel, which is inconvenient to install and requires two people to operate. One person inserts the bolts through the water seal pad 5, water seal, and water seal pressure plate 4 on one side of the door leaf panel, while the other person tightens the nuts on the other side of the door leaf panel. In contrast, this water seal structure is connected to one side of the door leaf panel only through the water seal pressure plate 4, eliminating the need for multiple people and improving the ease of installation.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
