Description

Technical Field

[0001] The utility model relates to the technical field of gates, and more particularly to a gate which is easy to open and close. Background Art

[0002] Gates are widely used in water supply and drainage projects such as municipal administration, petroleum, chemical industry, power station, metallurgy, coal, light industry, food, pharmaceutical, water conservancy, sewage treatment, etc. For nominal pressure below 0.1Mpa, they are used at pipe openings and intersection pits, muddy land, sewage channels, original station well water outlets, clear water tanks, etc. to cut off, dredge water flow or adjust water level. Gates can be used in combination with manual, electric, and hydraulic hoists to achieve on-site operation or remote centralized control, and can also be linked with microcomputer control.

[0003] In order to cope with the environment of higher pressure, the existing gates will be equipped with criss-cross reinforcing ribs on one of the surfaces of the gate plate, but there are defects during use. First, when the gate is in a closed state, the gate plate is completely immersed in the corresponding environment, and the side of the gate plate with reinforcing ribs will gradually adhere to and accumulate various impurities such as silt, and the overall quality of the gate plate will increase. Therefore, when the gate plate needs to be lifted upward, a greater driving force is required, resulting in difficulties in opening and closing the gate plate and easy damage to the valve stem; second, the maintenance cycle of the staff on the gate plate is short and the maintenance is difficult, which increases the labor cost of the user. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a gate which is easy to open and close, has a long maintenance cycle and is easy to maintain.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gate that is easy to open and close, comprising a door frame that can be externally connected to a pipeline, a gate plate that can move up and down relative to the door frame, and a valve stem that can drive the gate plate to move, a plurality of criss-cross reinforcing ribs are arranged on one side surface of the gate plate, and the plurality of reinforcing ribs divide the side surface of the gate plate into a plurality of mutually independent receiving grooves, and a plurality of drainage holes are opened in the gate plate from the top surface of the gate plate toward the valve stem, and the other ends of the plurality of drainage holes are respectively connected to the inner cavities of the plurality of receiving grooves, and the fluid flows through the drainage holes and flushes the impurities in the receiving grooves out of the receiving grooves by moving the gate plate upward.

[0006] As a further improvement of the utility model, the plurality of receiving grooves include a sliding surface for carrying impurities, the plurality of sliding surfaces are arc surfaces or inclined surfaces, and the inner cavity contour dimensions of the plurality of receiving grooves gradually increase in the direction from the gate plate to the notch of the receiving groove.

[0007] As a further improvement of the utility model, the openings of the plurality of drainage holes communicating with the corresponding receiving grooves are all located at the junction of the corresponding sliding surface and the bottom of the corresponding receiving groove.

[0008] As a further improvement of the utility model, a linkage part that can cover the multiple drainage holes and is connected to the valve stem is slidably connected above the gate plate. The linkage part moves up and down relative to the top surface of the gate plate to realize whether the openings of the multiple drainage holes on the top surface of the gate plate are connected to the outside world.

[0009] The beneficial effects of the utility model are as follows: by moving the gate upward, the fluid flows through the drainage hole and flushes the impurities in the receiving groove out of the receiving groove. Compared with the prior art, such a design can clean the receiving groove when the gate is opened, thereby reducing the weight of the gate. The gate can be cleaned and maintained each time it is opened, so that the weight change of the gate is small, which is convenient for opening and closing, and makes up for the defect of the prior art that the weight of the gate increases significantly due to the accumulation of impurities for many times or for a long time, making it difficult to open the gate. In terms of maintenance, it can effectively extend the maintenance cycle and reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments, wherein the same components are indicated by the same reference numerals.

[0017] Reference Figures 1 to 5 As shown, a gate that is easy to open and close in this embodiment includes a door frame 1 that can be externally connected to a pipeline, a gate plate 2 that can move up and down relative to the door frame 1, and a valve stem 3 that can drive the gate plate 2 to move. A plurality of crisscross reinforcing ribs 4 are arranged on one side of the gate plate 2. The plurality of reinforcing ribs 4 divide the side surface of the gate plate 2 into a plurality of mutually independent accommodating grooves 5.

[0018] Based on the above-mentioned prior art, the gate plate 2 includes a main plate and a sub-plate that can be assembled together. Half holes that can be assembled together are processed on the facing surfaces of the main plate and the sub-plate. A criss-cross reinforcing rib 4 is processed on the other surface of the main plate. End holes connected to the corresponding half holes are opened on the bottoms of the multiple accommodating grooves 5. After the main plate and the sub-plate are welded together, the half holes of the main plate, the end holes and the half holes of the sub-plate together form a drainage hole 6. The gate plate 2 is connected to the valve stem 3, and the valve stem 3 and the drainage hole 6 do not interfere with each other.

[0019] In the initial state, the gate plate 2 blocks the flow of the medium, and the impurities in the medium adhere to or stagnate in the multiple receiving grooves 5. When the valve stem 3 drives the gate plate 2 to move upward, the medium above the gate plate 2 will enter the drainage hole 6 and enter the receiving groove 5 along the drainage hole 6. The medium entering the receiving groove 5 pushes the impurities out of the receiving groove 5 and disperses them. In addition, medium convection will occur on one side of the gate plate 2, which accelerates the speed at which the impurities flow out of the receiving groove 5.

[0020] Compared with the prior art, such a design can clean the receiving groove 5 when the gate plate 2 is opened, thereby reducing the weight of the gate plate 2. The gate plate 2 can be cleaned and maintained each time it is opened, so that the weight change of the gate plate 2 is small, which is convenient for opening and closing. This makes up for the defect of the prior art that the gate plate 2 is difficult to open due to the accumulation of impurities for many times or for a long time; in terms of maintenance, it can effectively extend the maintenance cycle and reduce maintenance costs.

[0021] As a specific implementation method of the improvement, refer to Figure 3 As shown, the inner wall of the multiple receiving grooves 5 used to carry impurities is called a sliding surface 51, and the sliding surface 51 is designed to be an arc surface or a slope, and the inner cavity contour size of the multiple receiving grooves 5 gradually increases in the direction from the gate plate 2 to the notch of the receiving groove 5. Compared with the prior art design in which the inner wall used to carry impurities is made into a plane, such a design can guide the impurities to one side of the gate plate 2, slow down the accumulation speed of impurities in the receiving groove 5, and at the same time, when the medium enters the receiving groove 5 through the drainage hole 6, it speeds up the discharge of the impacted impurities to one side of the gate plate 2.

[0022] As a specific implementation method of the improvement, refer to Figure 3 As shown, the openings of the plurality of drainage holes 6 communicating with the corresponding receiving grooves 5 are all located at the junction of the corresponding sliding surface 51 and the bottom of the corresponding receiving groove 5. Such a design can ensure that the medium entering the receiving groove 5 first removes the impurities on the sliding surface 51. The impurity removal operation from the sliding surface 51 facilitates the impurities located at high places to collapse downward and disperse, thereby speeding up the cleaning of the impurities.

[0023] As a specific implementation of the improvement, since the opening of the drainage hole 6 on the top surface of the gate plate 2 is exposed, impurities will be stationary and blocked at the opening of the drainage hole 6, affecting the subsequent medium from entering the drainage hole 6. In order to solve the above problem, refer to Figures 3 to 5As shown, lugs are added at both ends of the top surface of the gate plate 2, and the two lugs are provided with sliding holes extending along the moving direction of the gate plate 2. A linkage member 7 is fixedly connected to one end of the valve stem 3. The length of the linkage member 7 is adapted to the distance between the two lugs. The linkage member 7 is hollow. The linkage member 7 is placed between the two lugs and a connecting rod is used to successively penetrate the lug, the linkage member 7 and the other lug. The sections of the connecting rod are respectively located in the two sliding holes. The bolts are screwed into the linkage member 7 from top to bottom so that the end of the bolt extending into the linkage member 7 touches the top of the connecting rod. Then, the connecting rod is fixedly connected to the linkage member 7, and the connecting rod and the linkage member 7 cannot rotate, and the connecting rod and the lug cannot rotate.

[0024] In the initial state, the gate plate 2 blocks the flow of the medium, the linkage member 7 is in contact with the top surface of the gate plate 2 and covers a plurality of drainage holes 6, and the ends of the connecting rods are all located at the bottom ends of the corresponding sliding holes; during the opening process of the gate plate 2, the valve stem 3 drives the linkage member 7 to move upward relative to the gate plate 2, and the ends of the connecting rods move upward along the corresponding sliding holes and touch the top ends of the sliding holes, and the openings of the plurality of drainage holes 6 located on the top surface of the gate plate 2 are all connected with the outside world, as the valve stem 3 continues to drive the linkage member 7 to move upward, the linkage member 7 drives the gate plate 2 to move upward through the connecting rod, the medium flows through the drainage holes 6 and can discharge the impurities in the containing groove 5; during the closing process of the gate plate 2, the linkage member 7 and the gate plate 2 move downward synchronously until the bottom of the gate plate 2 touches the outside world, the linkage member 7 moves downward relative to the gate plate 2 until the linkage member 7 is in contact with the top surface of the gate plate 2, and the valve stem 3 stops moving;

[0025] Such a design can make up for the defect that the opening of the drainage hole 6 is blocked, and ensure the cleaning operation of impurities when the gate plate 2 is opened later.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
