Description

Technical Field

[0001] The utility model relates to the technical field of submerged hole steel gates, in particular to a novel hollow plane working steel gate. Background Art

[0002] Gates can be divided into working gates, inspection gates and emergency gates according to their working nature. Working gates are also called main gates, which can be opened and closed in moving water. Inspection gates are located in front of working gates. They are used for short-term water blocking during the inspection of buildings or working gates, and are generally opened and closed in still water. Emergency gates are mostly located in front of deep-hole working gates. They can be closed in moving water and opened in still water when accidents occur in buildings or equipment. When they also serve as inspection gates, they are also called accident inspection gates. Due to the presence of the inspection gates and emergency gates in front, the water flow rate of the working gate is basically fixed. However, the gate panel of the traditional working gate is usually a closed whole with average strength. When working, the opening and closing device needs to be used to control the opening and closing degree of the door panel to adjust the water flow rate. The operation process is relatively cumbersome and is not suitable for some working conditions where the water flow rate needs to be controlled to a certain specific value. Utility Model Content

[0003] The utility model aims to provide a novel hollow plane working steel gate, so as to solve the problems that the traditional working gate has insufficient structural strength and is complicated to operate during use.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A new type of hollow plane working steel gate comprises a gate panel, a gate main cross beam and a gate vertical secondary beam. A plurality of hollow openings are evenly opened on the gate panel, and the gate main cross beam and the gate vertical secondary beam are cross-fixed on the back of the gate panel.

[0006] Furthermore, a plurality of counterweights are fixed to the back of the gate panel.

[0007] Furthermore, rubber and rubber pressure plates are arranged around the gate panel.

[0008] Furthermore, guide side sliding blocks are provided on two side edges of the gate panel.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0010] (1) The utility model provides a new type of hollow plane working steel gate, which avoids the need to frequently operate the opening and closing equipment to adjust the opening and closing degree of the gate panel by setting a gate panel with a hollow opening, thereby simplifying the operation process. In addition, by setting a main horizontal beam, a secondary vertical beam and a counterweight block on the back of the gate panel, the strength of the hollow gate panel is compensated and strengthened.

[0011] (2) The utility model is also provided with rubber and a rubber pressure plate to improve the sealing performance around the gate, and the guide side slider ensures that the gate will not deviate when falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the front and back structures of the gate of the utility model.

[0013] Explanation of the reference numerals: 1-gate panel, 2-hollow opening, 3-gate main beam, 4-gate vertical secondary beam, 5-gate body counterweight, 6-guide side slider, 7-rubber and rubber pressure plate. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention, so that other technicians in the field can better understand and reproduce the present invention.

[0015] like Figure 1 As shown, the left side of the dividing line is the back structure of the gate panel 1, and the right side is the front structure, which specifically includes the gate panel 1, the gate main cross beam 3 and the gate vertical secondary beam 4. A number of hollow openings 2 are evenly opened on the gate panel 1, and the gate main cross beam 3 and the gate vertical secondary beam 4 are cross-fixed on the back of the gate panel 1.

[0016] A plurality of counterweights 5 are fixed to the back of the gate panel 1 , rubber and rubber pressure plates 7 are arranged around the gate panel 1 , and guide side sliders 6 are arranged on the two side edges of the gate panel 1 .

[0017] Example:

[0018] The gate frame is composed of a gate main cross beam 3, a gate, and a gate vertical secondary beam 4, and adopts an I-shaped welded structure.

[0019] Before the gate was put into use, the flow channel design flow was 33.15m 3 / s; When the gate is put into use, the flow rate of the flow channel is 19.89~33.15m 3 / s, the area of ​​the hollow opening 2 on the panel is 30%, and the hollow panel is welded to the back water surface of the gate frame. The material is ordinary Q235B plate. The gate panel 1 is equipped with a rubber sealing structure around it, and a rubber pressure plate is set on the rubber to fix the sealing rubber. Through calculation, it is determined that the opening area of ​​the steel gate panel is 9m 2 .

[0020] Guide side slide blocks 6 are provided on both sides of the gate so that the gate can be smoothly placed at the gate opening.

[0021] Since the closing force of the gate when the water is moving is relatively large, a counterweight 5 is provided on the gate frame so that the gate can be safely placed at the orifice of the flow channel.

[0022] When working, when the gate is placed into the flow channel orifice through a special opening and closing tool, the gate sealing surface is placed downstream of the water flow. The gate is completely sealed on all sides at the orifice through the thrust of the upstream water. The upstream water can only flow out through the openings on the gate panel, thereby achieving the purpose of controlling the water flow rate of the gate.

[0023] The contents not described in detail in the above specification belong to the prior art known to those skilled in the art. Although the embodiments of the utility model have been shown and described, it is understandable to those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
