Description

Technical Field

[0001] The utility model relates to the field of flood control baffles, in particular to a suspension type flood control water gate used in a GCB room. Background Technique

[0002] The flood control water gate is mainly used to prevent rainwater or flood from entering low-lying areas, such as underground garages, subway stations, underground shopping malls in cities, or industrial factories near rivers and in low-lying areas, basements and underground parking lots in residential communities, etc. The Chinese utility model patent: CN202222509001.1 discloses a hydraulic water gate, which realizes the purpose of water blocking by digging a sinking groove in advance and cooperating with a lifting member to lift the water gate. However, when using this scheme, it generally needs to be embedded before the overall structure is poured or the installation pits and drainage measures are planned in advance. If it is necessary to transform the completed finished structure, a deep pit needs to be dug on the ground to place the hydraulic device, which causes great damage to the ground structure. Moreover, this structure lifts the water gate by a support member. If it is impacted by floating objects in the flood, the support member of the water gate may be damaged, causing the water gate to collapse. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies and design a new type of water gate. The entire water gate panel is laid flat on the ground, with columns on both sides and is driven by an electric winch. All structures of the utility model are above the ground. Only a small opening needs to be cut on the ground at the rotating shafts on both sides of the water gate, which causes little damage to the completed ground. Since all spare parts are above the ground, maintenance and installation are very convenient. At the same time, the water gate is supported by columns and door posts and is less likely to collapse.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A suspension type flood control water gate used in a GCB room, including two groups of columns symmetrically arranged on one side of the door post. An electric winch is arranged at the top of the column. A connecting plate is arranged at the bottom of the column on the side away from the door post. The bottom of the connecting plate is movably connected to the water gate panel through a water gate hinge. An H-shaped steel is arranged on the opposite side surfaces of the two groups of columns. A pulley group is arranged on the H-shaped steel. A limiting component is arranged at a position above the pulley group on the H-shaped steel. A fixed pulley is arranged on the pulley group on the side away from the column. The electric winch is fixedly connected to an anchor point on the water gate panel through a steel cable wound around the fixed pulley.

[0005] Preferably, the limiting component includes a limiting main board fixedly installed on the H-shaped steel. Support plates are vertically installed on both sides of the limiting main board. A support shaft penetrates through the support plates. Both ends of the support shaft are fixed by a limiting retaining piece located inside the support plate and a baffle located outside the support plate respectively.

[0006] Preferably, a rubber buffer pad is fixedly connected to the bottom of the limiting main board.

[0007] Preferably, the pulley block includes a pulley block main body disposed on the H-beam. Four limiting I-shaped wheels are installed in pairs inside the pulley block main body. The limiting I-shaped wheels are respectively disposed on both sides of the H-beam and slide along the H-beam. A fixed pulley is disposed on the side of the pulley block main body away from the H-beam.

[0008] Preferably, a door pusher is disposed on the side of the column away from the H-beam. The door pusher includes a door pusher main body installed on the column. A copper sleeve is disposed inside the door pusher main body in a direction perpendicular to the column. A spring is disposed at one end inside the copper sleeve. One end of the spring is elastically connected to a door pushing column, and the end of the door pushing column away from the spring extends outward through the door pusher main body.

[0009] Preferably, an outer limiting plate is disposed on the side of the door pusher main body where the spring is located, and an inner limiting plate is disposed on the side of the door pusher main body where the door pushing column is located.

[0010] Preferably, a side sensor is installed at the bottom of the door pusher.

[0011] Preferably, an alarm lamp and a monitoring camera are respectively disposed at the tops of the two groups of door columns.

[0012] Preferably, a sealing strip is disposed on the edge of the water blocking door panel close to the column.

[0013] Preferably, a sensor is disposed on the column at the bottom of the H-beam.

[0014] The beneficial effects of the present utility model are as follows:

[0015] First, the present utility model combines the fixed pulley on the pulley block to convert the oblique pulling force of the electric winch installed at the top of the column on the water blocking door panel into a pulling force perpendicular to the door panel after the door panel is completely vertical. The door panel fits more closely with the column, and the water blocking performance is better. Moreover, since all the structures of the present utility model are above the ground, it is not necessary to damage the ground, which is more convenient for subsequent replacement and maintenance. At the same time, the water blocking door is supported by the column and the door column, so the water blocking performance is better and it is not easy to collapse.

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation method and the accompanying drawings.

[0024] like Figure 1 Figure 5 As shown, a suspension bridge type flood control water retaining gate used in a GCB room comprises two groups of columns 3 symmetrically arranged on one side of the gate post, an electric winch 2 is arranged on the top of the column 3, a connecting plate is arranged on the bottom of the column 3 away from the gate post, and the bottom of the connecting plate is movably connected to the water retaining door plate 6 through the water retaining door hinge 10, and the two groups of columns 3 are arranged on the opposite sides, a pulley block 5 is arranged on the H steel, and a limit position component 4 is arranged on the H steel above the pulley block 5, and a fixed pulley 55 is arranged on the pulley block 5 away from the column 3. The electric winch 2 is connected to the fixed pulley 55 by a steel cable and fixedly connected to the anchor point on the water retaining door plate 6. In this embodiment, when in use, the electric winch 2 is started. The electric winch 2 is preferably a three-phase 380V 1.5-ton small winch, and a 220V winch can also be selected according to the actual power consumption on site. The electric winch 2 drives the steel cable to pull the water retaining door plate 6 up. It should be noted that if Figure 5As shown, after the steel cable leaves the electric winch 2, it bypasses the fixed pulley 55 on the pulley block 5 and is connected to the upper end anchor point of the water stop door. Specifically, when the electric winch 2 retracts the steel cable, since the weight of the pulley block 5 is less than the force required to pull the water stop door panel 6, at this time, the pulley block 5 moves upward along the H-shaped steel under the tension of the steel cable. After running to the upper limit component 4, it stops moving under the block of the limit component 4. At this time, the steel cable continues to drive the water stop door panel 6 to start moving upward. It should be noted that when the steel cable is parallel to the water stop door panel 6 through the fixed pulley 55 at the bottom of the column 3, it is impossible to lift the water stop door. Therefore, the pulley block 5 is set up. By raising the fixed pulley 55 to a certain height through the pulley block 5, an angle for the steel cable to lift the water stop door panel 6 is given, and then the water stop door panel 6 can be lifted. When the water stop door panel 6 needs to be opened, the electric winch 2 releases the steel cable, and the water stop door panel slowly moves to the fully open horizontal state under gravity. By continuously releasing the steel cable, when the tension of the steel cable on the pulley block 5 is less than the gravity of the pulley block 5, the pulley block 5 slowly descends to the ground. At this time, the steel cable also fully adheres to the ground, pressing the steel cable to the ground to prevent staff from tripping.

[0025] As Figure 2 shown, preferably, the limit component 4 includes a limit main board 41 fixedly installed on the H-shaped steel. On both sides of the limit main board 41, support plates 44 are vertically installed. A support shaft 42 is penetrated through the support plates 44. Both ends of the support shaft 42 are fixed by a limit stop piece 43 located inside the support plate 44 and a baffle 45 located outside the support plate 44. The limit component 4 is fixed on the H-shaped steel. During use, the steel cable passes through the side of the support shaft 42. The support shaft 42 is mainly used for supporting the steel cable to prevent the steel cable coming out of the winch from interfering with the H-shaped steel, and can also support the steel cable coming out of the winch to the same working surface as the water stop door panel 6 and the fixed pulley 55.

[0026] Preferably, a rubber buffer pad 46 is fixedly connected to the bottom of the limit main board 41. As Figure 2 shown, preferably, the top of the rubber buffer pad 46 is fixed to the limit main board 41 by two connecting plates. The rubber buffer pad 46 is perpendicular to the limit main board 41. At the same time, the buffer pad is provided with bolt mounting holes and can be detachably fixed to the limit board main body 41 by L-shaped bolts. The rubber buffer pad 46 is used for the overall buffering effect of the upper positioning when the pulley block 5 runs.

[0027] As Figure 4As shown, preferably, the pulley block 5 includes a pulley block main body 51 arranged on the H-beam. Inside the pulley block main body 51, four limiting I-shaped wheels 52 are installed in pairs. The limiting I-shaped wheels 52 are respectively arranged on both sides of the H-beam and slide along the H-beam. On the side of the pulley block main body 51 away from the H-beam, a fixed pulley 55 is provided. In this embodiment: the pulley block 5 is a track pulley for I-beams. On the side of the pulley block 5 close to the H-beam, an outer limiting column 63 and an inner limiting roller 64 are installed. When in use, the limiting I-shaped wheels 52 slide along both sides of the H-beam. On both sides of the pulley block main body 51 close to the H-beam, fixing plates are installed. An inner limiting column 63 is arranged between the fixing plates to further enhance the stability of the pulley block 5, and an inner limiting roller 64 is installed between the fixing plates. The inner limiting roller 64 slides along the surface of the H-beam to further increase the sliding efficiency of the pulley block.

[0028] As Figure 1 Figure 3 shown, preferably, on the side of the column 3 away from the H-beam, a door pusher 8 is provided. The door pusher 8 includes a door pusher main body 81 installed on the column 3. Inside the door pusher main body 81, a copper sleeve 83 is arranged perpendicular to the direction of the column 3. At one end inside the copper sleeve 83, a spring 84 is provided. One end of the spring 84 is elastically connected to a door pushing column 85. The end of the door pushing column 85 away from the spring 84 extends outwards through the door pusher main body 81. In this embodiment, the door pushing column 85 can slide freely inside the copper sleeve. When the water blocking door panel 6 is closed, the electric winch 2 retracts the steel cable. At this time, the force exerted by the water blocking door panel 6 to compress the door pushing column 85 under the pulling force of the electric winch 2 is greater than the pressure of the spring 84 on the door pushing column 85, and the water blocking door panel 6 will move the door pushing column 85 inwards to compress the spring 84. When the flood recedes and the water blocking door panel 6 needs to be opened, the electric winch 2 continuously releases the steel cable, and the spring of the door pusher releases pressure to push the door pushing column 85. After the door pushing column 85 pushes the water blocking door panel 6 to tilt at an angle (the center of gravity of the water blocking door is outside the position of the hinge of the water blocking door), then under the action of the self-gravity of the water blocking door panel 6, it slowly opens to the ground.

[0029] Preferably, on the side of the door pusher main body 81 where the spring 84 is located, an outer limiting plate 82 is provided, and on the side of the door pusher main body 81 where the door pushing column 85 is located, an inner limiting plate 86 is provided. The outer limiting plate 82 and the inner limiting plate 86 are used to prevent the spring 84 and the door pushing column 85 from detaching from the copper sleeve 83.

[0030] Preferably, a side sensor 11 is installed at the bottom of the door pusher 8. When in use, when the steel cable pulls the water blocking door panel 6 to be vertical and close to the column 3; when the side sensor 11 detects that the water blocking door is close, the winch powers off and locks itself.

[0031] Preferably, alarm lights 7 and monitoring cameras 1 are respectively provided at the tops of the two groups of door columns. In this embodiment, a camera 1 for on-site monitoring is installed at the top of the door column, and the monitoring can be transmitted to the guard room. The alarm lights can emit sound and light alarms during the operation of the equipment.

[0032] Preferably, a sealing strip is provided on the edge of the water retaining door panel 6 close to the column 3. In this embodiment, when in use, under the tension of the steel cable and the pressure of water, the sealing strip arranged along the perimeter of the water retaining door panel 6 is completely pressed tightly, and at this time, the sealing effect can be achieved.

[0033] Such as Figure 6 shown, preferably, a sensor 9 is provided at the bottom of the H-beam on the column 3. When in use, the sensor 9 installed at the bottom of the H-beam cooperates with the side sensor 11 below the door pusher 8 to further receive the opening and closing signals of the water retaining door panel 6.

[0034] Specific use steps of the present utility model: When the present utility model is working, an external power supply is used as the power supply, and the electric winch 2 on the column 3 is used as the power source. When the guard room senses the approaching flood through monitoring or nearby staff, first click the start button in the guard room or the start button installed beside the equipment, and the electric winches 2 on both sides of the column 3 work simultaneously to tighten the steel cable; the alarm lamp 7 gives out sound and light alarms. At this time, according to the monitoring or on-site situation, when there are people, vehicles or large floating objects approaching or blocking, the operation of the equipment is paused; then the pulley block 5 moves upward under the tension of the steel cable on the winch and is fixed below the limit plate; the steel cable pulls the water retaining door panel 6 to be vertical and closely abuts against the column 3; when the sensor detects that the water retaining door is closely abutted, the winch cuts off the power supply and self-locks, and the water retaining door panel 6 presses the sealing strip around it completely under the tension of the steel cable and the pressure of water, and at this time, the sealing effect can be achieved.

[0035] When the flood has passed: First, after determining that the lowering of the water retaining door panel 6 will not affect the surrounding people and cleaning the ground area where the water retaining door panel 6 is laid flat, press the opening button installed beside the equipment; then the water retaining door panel 6 gives out sound and light alarms, and the electric winch 2 relaxes the steel cable; the water retaining door panel 6 tilts at an angle under the push of the door pusher 8, and then slowly lies flat under the action of the gravity of the water retaining door panel 6. When lying flat, it is necessary to always pay attention to the safety situation around to prevent people, vehicles or other foreign objects from entering under the water retaining door until the water retaining door panel 6 is completely laid flat; finally, after the water retaining door panel 6 is laid flat, the winch continues to relax the steel cable, and the pulley block slowly falls to the ground under its own gravity, pressing the steel cable to the ground as well, and the winch cuts off the power supply to complete the operation.

[0036] It should be understood that the above detailed description of the specific embodiments of the present invention with reference to the accompanying drawings does not limit the patent scope of the present invention. Any equivalent transformation made using the content of the specification and drawings of the present invention, directly or indirectly applied in the relevant technical fields, is covered by the protection scope of the present invention.
