Description

Technical Field

[0001] This utility model relates to the field of gates, specifically a lifting gate for water conservancy projects. Background Technology

[0002] Lift gates are a very common and widely used type of hydraulic gate. Their core feature is that the gate leaf (water-retaining panel) can move up and down along a vertical or near-vertical track, thereby opening and closing the waterway.

[0003] There is a type of lifting gate on the market, whose gate frame has a slot formed at the bottom for the gate leaf to be inserted. A good sealing effect can be achieved by inserting the bottom of the gate leaf into the slot. However, when the gate leaf is in the open state for a long time, if the water flow contains impurities such as mud, sand, leaves, and domestic waste, the impurities can easily enter the slot, causing the gate leaf to fail to close tightly in the future. Based on this, in order to avoid this situation, a lifting gate for water conservancy projects is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting gate for water conservancy projects in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting gate for water conservancy projects, comprising a gate assembly consisting of a gate frame, a rectangular slot, a hoist, gate leaves, and guide wheels. The rectangular slot is located on both sides and the bottom of the gate frame and extends through the top of the gate frame. The hoist is installed on the top of the gate frame, and the bottom end of the hoist's lifting screw is connected to the gate leaf. The two sides of the gate leaf are slidably installed inside the two sides of the rectangular slot, and the bottom of the gate leaf is inserted into the bottom inner side of the rectangular slot. The guide wheels are symmetrically installed on both sides of the gate leaf, and the rollers of the guide wheels roll against the inner wall of the rectangular slot. An auxiliary sealing assembly is provided on the inner side of the rectangular slot and the top of the gate leaf. The auxiliary sealing assembly is used to seal the bottom port of the rectangular slot when the gate leaf is raised.

[0006] The auxiliary blocking component includes a linkage blocking unit, a locking unit, and an unlocking unit;

[0007] The linkage sealing unit uses the lifting force of the door leaf to seal the bottom port of the rectangular slot;

[0008] The locking unit is used to lock the linkage blocking unit in its rising state;

[0009] The unlocking unit utilizes the descending force of the door leaf to unlock the linkage sealing unit.

[0010] As a further improvement of this utility model: the linkage sealing unit includes a sealing base plate and a 7-shaped pull plate;

[0011] The sealing base plate is slidably installed on the inner bottom of the rectangular slot and located at the bottom end of the door leaf;

[0012] The 7-shaped pull plates are provided in four pairs and are symmetrically fixed to the top two sides of the sealing base plate. The two 7-shaped pull plates distributed on the same side are symmetrically distributed with the guide wheel as the center. The vertical part of the 7-shaped pull plate is attached to the side of the door leaf, the inner wall of the rectangular slot and extends to the top of the door leaf. The top horizontal part of the 7-shaped pull plate is located on the rising path of the door leaf.

[0013] When the gate leaf moves upward and contacts the top horizontal part of the 7-shaped pull plate, the 7-shaped pull plate and the sealing bottom plate are pulled up simultaneously. The sealing bottom plate rises up and becomes flush with the bottom of the inner wall of the gate frame, which is used to seal the bottom port of the rectangular slot.

[0014] As a further embodiment of this utility model: the locking unit includes a fixing pin, a toothed roller, and an L-shaped hook;

[0015] The fixing pin is fixed in the middle of the horizontal part of the top of the two 7-shaped pull plates;

[0016] The toothed roller is rotatably mounted on the top inner side of the rectangular slot via a rotating shaft, and the L-shaped hook is fixed to the bottom of the toothed roller. The bottom hook of the L-shaped hook is located on the rising path of the fixing pin.

[0017] When the fixing pin rises and contacts the inclined surface of the hook at the bottom of the L-shaped hook, it squeezes the L-shaped hook to deflect as a whole. When the fixing pin rises above the hook at the bottom of the L-shaped hook, the L-shaped hook resets under its own weight, realizing the hook engagement operation between the hook and the bottom of the fixing pin.

[0018] As a further improvement of this utility model: the unlocking unit includes a connecting arm and a toothed plate;

[0019] The connecting arms are symmetrically fixed on both sides of the top of the door leaf, and the connecting arms are located in the middle of the vertical part of the two 7-shaped pull plates. The top of the connecting arms extends upward to the top of the 7-shaped pull plates and is fixedly connected to the toothed plate.

[0020] The toothed plate is fixed to the top of the 7-shaped pull plate near the door leaf. The downward-moving toothed plate contacts and meshes with the toothed roller, which is used to drive the toothed roller and the L-shaped hook to rotate as a whole.

[0021] As a further improvement of this utility model: when the door leaf is in the closed state, the toothed plate is in the lowest position and is engaged with the toothed roller.

[0022] As a further improvement of this utility model: the width of the connecting arm matches the spacing between the two 7-shaped pull plates, and the side of the connecting arm away from the door leaf is in contact with the inner wall side of the rectangular slot.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By setting up an auxiliary sealing component, when the leaf gate moves upward and opens, the sealing base plate seals the bottom port of the rectangular slot, preventing impurities in the water flow from settling at the bottom of the rectangular slot. This ensures the normal operation of the leaf gate when it closes later. The lifting and unlocking driving force of the auxiliary sealing component comes from the lifting force of the leaf gate. The structure is simple and easy to operate. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5In this embodiment of the present invention, a lifting hydraulic engineering gate includes a gate assembly 1 consisting of a gate frame 101, a rectangular slot 102, a hoist 103, a gate leaf 104, and guide wheels 105. The rectangular slot 102 is opened on both sides and the bottom of the gate frame 101 and penetrates the top of the gate frame 101. The hoist 103 is installed on the top of the gate frame 101. The bottom end of the hoist 103's lifting screw is connected to the gate leaf 104. The two sides of the gate leaf 104 are slidably installed inside the two sides of the rectangular slot 102. The bottom of the gate leaf 104 is inserted into the bottom inner side of the rectangular slot 102. The guide wheels 105 are symmetrically installed on both sides of the gate leaf 104, and the rollers of the guide wheels 105 roll and fit against the inner wall side of the rectangular slot 102. An auxiliary sealing assembly 2 is provided on the inner side of the rectangular slot 102 and the top of the gate leaf 104. The auxiliary sealing assembly 2 is used to seal the bottom port of the rectangular slot 102 when the gate leaf 104 is raised.

[0033] The auxiliary blocking component 2 includes a linkage blocking unit, a locking unit, and an unlocking unit. The linkage blocking unit uses the upward force of the door leaf 104 to block the bottom port of the rectangular slot 102. The locking unit is used to lock the linkage blocking unit in its upward state. The unlocking unit uses the downward force of the door leaf 104 to unlock the linkage blocking unit.

[0034] The linkage sealing unit includes a sealing base plate 201 and a 7-shaped pull plate 202;

[0035] The sealing base plate 201 is slidably installed on the inner bottom of the rectangular slot 102 and located at the bottom end of the door leaf 104;

[0036] Four 7-shaped pull plates 202 are provided and symmetrically fixed to the top two sides of the sealing base plate 201 in pairs. Two 7-shaped pull plates 202 distributed on the same side are symmetrically distributed with the guide wheel 105 as the center. The vertical part of the 7-shaped pull plate 202 is attached to the side of the door leaf 104, the inner wall of the rectangular slot 102 and extends to the top of the door leaf 104. The top horizontal part of the 7-shaped pull plate 202 is located on the rising path of the door leaf 104.

[0037] When the gate leaf 104 moves upward and contacts the top horizontal part of the 7-shaped pull plate 202, the 7-shaped pull plate 202 and the sealing bottom plate 201 are pulled up simultaneously. The sealing bottom plate 201 rises up and becomes flush with the bottom of the inner wall of the gate frame 101, which is used to seal the bottom port of the rectangular slot 102.

[0038] The locking unit includes a fixing pin 203, a toothed roller 204, and an L-shaped hook 205;

[0039] The fixing pin 203 is fixed to the middle of the top horizontal part of the two 7-shaped pull plates 202;

[0040] The toothed roller 204 is rotatably mounted on the top inner side of the rectangular slot 102 via a rotating shaft, and the L-shaped hook 205 is fixed to the bottom of the toothed roller 204. The bottom hook of the L-shaped hook 205 is located on the rising path of the fixing pin 203.

[0041] When the fixed pin 203 rises and contacts the inclined surface of the hook at the bottom of the L-shaped hook 205, it squeezes the L-shaped hook 205 and causes it to deflect as a whole. When the fixed pin 203 rises above the hook at the bottom of the L-shaped hook 205, the L-shaped hook 205 resets under its own weight, thus realizing the hook-on operation of the hook at the bottom of the fixed pin 203.

[0042] The unlocking unit includes a connecting arm 206 and a toothed plate 207;

[0043] The connecting arm 206 is symmetrically fixed on both sides of the top of the door leaf 104, and the connecting arm 206 is located in the middle of the vertical part of the two 7-shaped pull plates 202. The top of the connecting arm 206 extends upward to the top of the 7-shaped pull plate 202 and is fixedly connected to the toothed plate 207.

[0044] The toothed plate 207 is fixed to the top of the 7-shaped pull plate 202 on the side near the door leaf 104. The downward-moving toothed plate 207 contacts and meshes with the toothed roller 204 to drive the toothed roller 204 and the L-shaped hook 205 to rotate as a whole. When the door leaf 104 is in the closed state, the toothed plate 207 is in the lowest position and is meshed with the toothed roller 204.

[0045] In this embodiment, it should be noted that when this gate assembly 1 is in use, the leaf gate 104 is equipped with a gate water seal (also known as a P-type rubber waterstop) facing the direction of the intercepted water flow, which is used to achieve the sealing between the leaf gate 104 and the gate frame 101. This structure is the conventional structure of existing gates, so it is not drawn or described in detail here.

[0046] Yemen 104 is normally closed (e.g.) Figure 1 , 2 The bottom of the leaf gate 104 is inserted into the bottom of the rectangular slot 102 and fits against the sealing base plate 201. When the leaf gate 104 is opened, its operating principle is as follows:

[0047] The gate 104 is raised by starting the hoist 103 (the hoist 103 can be electric or manual as needed). During the initial rising process of the gate 104, the toothed plate 207 rises synchronously, driving the toothed roller 204 to rotate, which in turn causes the L-shaped hook 205 to rotate downward from the inclined upward state. When the toothed plate 207 separates from the toothed roller 204, the L-shaped hook 205 is in the vertical downward state (at this time, the top of the gate 104 has not yet contacted the top horizontal part of the 7-shaped pull plate 202).

[0048] Afterwards, the leaf gate 104 continues to rise and contacts the top horizontal part of the 7-shaped pull plate 202, thereby pushing the 7-shaped pull plate 202 to move upward synchronously. The 7-shaped pull plate 202 pulls the sealing base plate 201 upward. Finally, the upper surface of the sealing base plate 201 is flush with the bottom surface of the inner wall of the gate frame 101, thereby achieving the sealing of the bottom port of the rectangular slot 102.

[0049] At the same time, during the upward movement of the 7-shaped pull plate 202, the fixing pin 203 contacts the inclined surface of the bottom hook of the L-shaped hook 205 and forms a pressure on it. Under this pressure, the L-shaped hook 205 and the toothed roller 204 rotate as a whole. The L-shaped hook 205 rotates so that it does not block the upward movement of the fixing pin 203. When the fixing pin 203 moves up to above the hook of the L-shaped hook 205, the L-shaped hook 205 rotates downward and resets under its own weight. Finally, the hook of the L-shaped hook 205 forms a hook operation on the bottom of the fixing pin 203.

[0050] By sealing the bottom port of the rectangular slot 102 with the sealing plate 201, impurities in the water flow will not be deposited at the bottom of the rectangular slot 102, thereby ensuring the normal operation of the leaf door 104 in the later closing process.

[0051] During the closing and downward movement of the leaf gate 104, the 7-shaped pull plate 202 and the sealing base plate 201 remain stationary under the action of the L-shaped hook 205. When the bottom of the leaf gate 104 approaches the sealing base plate 201, the toothed plate 207 contacts and engages with the toothed roller 204. Then, the toothed plate 207 moves downward to drive the toothed roller 204 to rotate. The toothed roller 204 drives the L-shaped hook 205 to flip upward to release the engagement state with the fixing pin 203. At the same time, the bottom of the leaf gate 104 contacts the sealing base plate 201 and forms a pressure on it, causing the sealing base plate 201 to move downward, thus not blocking the bottom of the leaf gate 104 from inserting into the rectangular slot 102.

[0052] Please refer to this carefully. Figures 2-4 The width of the connecting arm 206 matches the spacing between the two 7-shaped pull plates 202, and the side of the connecting arm 206 away from the door leaf 104 is in contact with the inner wall side of the rectangular slot 102.

[0053] In this embodiment: This structure enables the connecting arm 206 to remain stable and undeformed when the toothed plate 207 and the toothed roller 204 are in contact and meshing, thus keeping the meshing state between the toothed plate 207 and the toothed roller 204 stable.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
