Description

Technical Field

[0001] This utility model relates to the field of arc-shaped steel gates, specifically a new type of tongue-shaped arc-shaped steel gate. Background Technology

[0002] An arc-shaped gate is a gate with a partially arc-shaped cylindrical water-retaining surface. Its supporting hinge is located at the center of the cylinder, and the gate rotates around this hinge during opening and closing. An arc-shaped gate consists of three parts: a rotating gate body, embedded components, and opening and closing equipment. Arc-shaped gates do not have a gate slot, require less opening and closing force, and have good hydraulic conditions, making them widely used as working gates in various types of waterways.

[0003] In the prior art, arc-shaped gates are generally installed in the laid waterways. Each time the gate is opened, the water flows through the waterway to the other side. When the water flows through, it usually carries mud and other debris, which causes the mud and other debris to accumulate on one side of the arc-shaped gate. In order to avoid the water flow being affected by mud and sand, this utility model proposes a new type of tongue-shaped arc-shaped steel gate. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of tongue-shaped arc-shaped steel gate in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel tongue-shaped arc-shaped steel gate, comprising a waterway, a support rod rotatably connected to the inner side of the waterway, a cylinder hinged to the top of the support rod on the inner side of the waterway, a valve plate fixedly connected to the end of the support rod, and a cleaning mechanism provided on the waterway and the support rod.

[0006] The cleaning mechanism includes a cleaning unit and a transmission unit;

[0007] The transmission unit is used to drive the cleaning unit to move axially.

[0008] The cleaning unit is used to scrape off the mud and sand adhering to the bottom of the waterway.

[0009] As a further embodiment of this utility model: the transmission unit includes a first pull rod, a second pull rod, and a fixed rod;

[0010] The first pull rod is fixed to the bottom of the support rod, and the first pull rod is used to pull one end of the second pull rod to move.

[0011] The second pull rod is rotatably connected to the bottom end of the first pull rod, and the second pull rod is used to pull one end of the fixed rod to move axially.

[0012] The fixing rod is rotatably connected to the bottom end of the fixing rod, and the fixing rod is used to synchronously drive the cleaning plate to move axially.

[0013] As a further improvement of this utility model: the cleaning unit includes a cleaning plate and a guide rod;

[0014] The cleaning plate is fixed to the end of the fixing rod and is flush with the bottom of the waterway. The cleaning plate is used to scrape away the silt and sand accumulated at the bottom of the waterway.

[0015] The guide rod is fixed to the bottom of the waterway and extends above the cleaning plate, and the guide rod is used to guide the axial movement of the cleaning plate.

[0016] As a further embodiment of this utility model: the outer wall cross-section of the cleaning plate is triangular, the bottom of the cleaning plate is flush with the bottom of the waterway, and the two sides of the cleaning plate are inclined.

[0017] As a further improvement of this utility model: the outer wall of the guide rod is generally L-shaped, and the inner side of the guide rod is flush with the height of the cleaning plate.

[0018] As a further embodiment of this utility model, there are two first pull rods, two second pull rods, and two fixing rods, which are symmetrically distributed at the bottom of the support rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By setting up a cleaning mechanism, when the valve plate is opened by the cylinder and support rod, the valve plate rotates around the connection between the support rod and the waterway. The first pull rod fixed at the bottom of the rotating support rod and the second pull rod rotatably connected will also pull the fixed rod and the cleaning plate axially. Under the action of the guide rod, the cleaning plate moves axially along the inner cavity of the guide rod, so that the cleaning rod moves along the bottom of the waterway to scrape off the mud and sand accumulated at the bottom of the waterway, which facilitates subsequent cleaning and further improves work efficiency.

[0025] 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.

[0026] Please see Figures 1-3 In this embodiment of the utility model, a novel tongue-shaped arc-shaped steel gate includes a waterway 1, a support rod 2 rotatably connected to the inner side of the waterway 1, a cylinder 3 hinged to the top of the support rod 2 on the inner side of the waterway 1, a valve plate 4 fixedly connected to the end of the support rod 2, and a cleaning mechanism 5 provided on the waterway 1 and the support rod 2.

[0027] The cleaning mechanism 5 includes a cleaning unit and a transmission unit;

[0028] The transmission unit is used to drive the cleaning unit to move axially;

[0029] The cleaning unit is used to scrape off the mud and sand adhering to the bottom of waterway 1;

[0030] The transmission unit includes a first pull rod 501, a second pull rod 502, and a fixed rod 503;

[0031] The first pull rod 501 is fixed to the bottom of the support rod 2, and the first pull rod 501 is used to pull one end of the second pull rod 502 to move.

[0032] The second pull rod 502 is rotatably connected to the bottom end of the first pull rod 501, and the second pull rod 502 is used to pull one end of the fixed rod 503 to move axially.

[0033] The fixing rod 503 is rotatably connected to the bottom end of the fixing rod 504, and the fixing rod 503 is used to synchronously drive the cleaning plate 504 to move axially.

[0034] The cleaning unit includes a cleaning plate 504 and a guide rod 505;

[0035] The cleaning plate 504 is fixed to the end of the fixing rod 503 and is flush with the bottom of the waterway 1. The cleaning plate 504 is used to scrape away the silt accumulated at the bottom of the waterway 1.

[0036] The guide rod 505 is fixed to the bottom of the waterway 1 and extends above the cleaning plate 504. The guide rod 505 is used to guide the axial movement of the cleaning plate 504.

[0037] In this embodiment: by activating the support rod 2 and the cylinder 3, the valve plate 4 rotates around the support rod 2 with the axis at the connection between the support rod 2 and the waterway 1 as the midpoint, so that the bottom of the valve plate 4 no longer touches the bottom of the waterway 1, and the water flow of the arc-shaped protrusion of the valve plate 4 enters the interior of the waterway 1.

[0038] During the lifting of the valve plate 4, one end of the first pull rod 501 fixed at the bottom of the support rod 2 will also move upward with the rotation of the support rod 2. The circumferential movement of one end of the first pull rod 501 around the rotation axis of the support rod 2 will pull one end of the second pull rod 502 connected to the other end of the first pull rod 501 toward the valve plate 4, so that the second pull rod 502 will transmit the pulling force to the fixed rod 503 and the cleaning plate 504. Due to the influence of the guide rod 505, the cleaning plate 504 is subjected to the influence of the guide rod 505. When the fixed rod 503 is pulled, the cleaning plate 504 will move axially along the inner cavity of the guide rod 505 toward the valve plate 4. The cleaning plate 504, which is in contact with the bottom of the waterway 1, will scrape the mud and sand accumulated at the bottom of the waterway 1. As water flows in from one side of the valve plate 4, it will clean the scraped mud and sand. When the valve plate 4 is closed, the cleaning plate 504 returns to its original position and scrapes and cleans the bottom of the waterway 1 again, so that the accumulated mud and sand are separated from the bottom of the waterway 1, which facilitates subsequent manual cleaning and further improves work efficiency.

[0039] Please refer to this carefully. Figures 1-3 The outer wall cross-section of the cleaning plate 504 is triangular, the bottom of the cleaning plate 504 is flush with the bottom of the waterway 1, and the two sides of the cleaning plate 504 are inclined. The outer wall of the guide rod 505 is generally L-shaped, and the inner side of the guide rod 505 is flush with the height of the cleaning plate 504. There are two first pull rods 501, second pull rods 502, and fixed rods 503. The two first pull rods 501, second pull rods 502, and fixed rods 503 are symmetrically distributed at the bottom of the support rod 2.

[0040] In this embodiment: With this structure, the mud and sand at the bottom of the waterway 1 can be cleaned and scraped by the inclined surfaces on both sides of the cleaning plate 504 under the axial movement of the cleaning plate 504, so that the mud and sand adhering to the bottom of the waterway 1 can be separated from the waterway 1, which is convenient for subsequent manual cleaning.

[0041] 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.
