TECHNICAL FIELD

[0001] The present application belongs to the technical field of water treatment, and particularly relates to a sealing device for a plug-in gate and the gate. BACKGROUND

[0002] In the field of water treatment, a water gate is a common waterway control device that can be used to intercept water flow, control flow, discharge sewage residues, etc. The plug-in gate is the most commonly used water gate, mainly including a door frame and a door body, the door body vertically lifts in the door frame, and in order to achieve better interception effect, a sealing rubber is also put into the door frame. However, the conventional plug-in gate sealing device is directly embedded in the civil engineering, and during the actual installation of the gate, due to installation errors, the gate and the sealing rubber may not be tightly matched, and water leakage may occur. In addition, the fixing method of the rubber in the sealing device is to punch holes on the door frame and the sealing rubber strip, and to fix them by screws or rivets. This production method is low in efficiency and long in production cycle. At the same time, frequent lifting of the gate can easily wear the sealing rubber strip, and the rubber strip is not easy to replace after being worn, which not only wastes financial resources but also increases the work intensity of construction workers.

DETAILED DESCRIPTION

[0027] The present application will be further described in conjunction with the accompanying drawings and specific embodiments, but the scope of protection of the present application is not limited thereto.

[0028] Example 1

[0029] Figure 1The diagram illustrates one embodiment of the novel sealing device for a gate according to the present invention. The novel sealing device comprises a side gate groove 1 and a sealing rubber strip 2. The side gate groove 1 has a rectangular cross-section with an opening on one side and can be formed by bending a steel plate. The sealing rubber strip 2 has a base 201 and an extension 202. The base 201 has a rectangular outer contour and is hollow internally. A gate receiving opening 203 is located at a position corresponding to the opening on the side gate groove 1. The extension 202 is connected to the gate receiving opening 203. The base 201 of the sealing rubber strip 2 is accommodated within the side gate groove 1, and the extension 202 extends from the opening of the rectangular structure. The novel sealing device for a gate according to the present invention allows the sealing rubber strip 2 to be directly inserted into the side gate groove 1 with an opening on one side, thereby achieving a drilling-free installation of the sealing rubber strip 2 and the side gate groove 1.

[0030] Furthermore, the side gate groove 1 has an outwardly extending stop portion 101 at its opening, which provides pressure for the seal between the outer extension portion 202 of the sealing rubber strip 2 and the gate.

[0031] The spacing between the two outer extensions 202 of the formed sealing rubber strip 2 should be 5-8mm. Under this size, the gate 3 can be inserted into the spacing of the sealing rubber strip 2, thereby achieving water-stop sealing at the gate body.

[0032] Example 2

[0033] like Figure 2 As shown, as an improvement to Embodiment 1, the top of the outer extension 202 of the sealing rubber strip 2 is configured to bend to both sides, and a hard coating 204 is provided on the surface of the bent portion. By configuring the top of the outer extension 202 of the sealing rubber strip 2 to bend to both sides, repeated friction of the gate can prevent the rubber strip 2 from being pulled into the side gate groove 1 due to frictional force, causing it to bend and stack, thus affecting the smooth closing and closing effect of the gate. The hard coating 204 can guide the gate when it is inserted into the sealing rubber strip, and also prevents wear on the rubber.

[0034] Example 3

[0035] like Figure 4 As shown, a small hole 205 is opened at the bottom of the sealing rubber strip 2 installed in the side gate groove 1. A groove is provided at the bottom of the bottom surface of the side gate groove 1 opposite to the opening. A pulley 11 is installed in the groove. One end of the traction line 10 passes through the small hole 205 and is detachably fixedly connected to the sealing rubber strip 2; the other end passes around the bottom of the pulley 11 and extends through the pipe 12 pre-embedded in the civil engineering to the upper part of the gate civil engineering. Figure 5As shown in the diagram. This structure allows for easier and faster replacement of the sealing rubber strip 2 when it is damaged. This is achieved by simply pulling out the damaged sealing rubber strip 2, placing the new sealing rubber strip 2 into the side gate slot 1, and then pulling the traction rope upwards. This also effectively extends the service life of the gate and reduces the workload required to replace the sealing rubber strip 2.

[0036] Example 4

[0037] like Figure 6 As shown, the side gate slot 1 has a spliced ​​structure, with the splice seam parallel to the long axis of the side gate slot 1. The splice is located at the angle between the bottom plate 102 and the two side panels 103 of the side gate slot 1, and the bottom plate 102 and the side panels 103 are connected by a hinge 6. The spliced ​​structure makes it easier to place the sealing rubber strip 2 inside the side gate slot 1 during the production process. Alternatively, as... Figure 7 As shown, the base plate 102 and the side plate 103 are fixedly connected by a right-angle steel 4 and a first bolt 5.

[0038] Example 5

[0039] The side gate slot 1 can also be spliced ​​using the following scheme: such as Figure 8 As shown, the splice of the side gate groove 1 is placed on two side panels 103, and then the base plate 102 and the side panel 103 are fixedly connected by the fixing plate 7 perpendicular to the splice seam and the second bolt 8. The splice of the side panel 103 is a stepped splice.

[0040] Example 6

[0041] Gate 3, which is used in conjunction with the gate sealing device, such as Figure 3 As shown, the gate 3 is composed of two steel plates joined together, with a square tube 301 installed at the joint, and the steel plates are welded and fixed to the square tube 301. A nut 9 matching a lead screw is installed at both ends of the square tube 301. Multiple stiffening plates 302 are evenly welded to the two steel plates, arranged perpendicular to the square tube 301. A groove 303 is located at the connection between the stiffening plate 302 and the steel plate, forming a through hole between the groove 303 and the steel plate. Multiple balls or rollers are installed at the contact points between the gate 3 and the sealing rubber strip 2. When the side of the gate 3 is embedded in the sealing rubber strip 2, the balls or rollers contact the inner side of the outer extension 202 of the sealing rubber strip 2. Compared to previous gate designs, the steel plates and square tubes 301 required for this gate are readily available and do not require extensive processing. In addition, the stiffener 302 used in this invention adopts an intermittent hollow design. When the gate is opened, some of the water remaining above the stiffener 302 will flow out from the hollow part of the stiffener 302. This structure reduces the opening and closing force required to open the gate 3, and the hollow design is also more aesthetically pleasing from a visual point of view. It is also more convenient and efficient to weld. At the same time, the square tube 301 can also protect the lead rod well.

[0042] The above embodiments are preferred embodiments of the present application, but the present application is not limited to the above embodiments, and any obvious modifications, replacements or variations made by those skilled in the art without departing from the spirit of the present application shall fall within the scope of protection of the present application.
