[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Figure 2 for Figure 1 Frontal view of;

[0023] Figure 3 for Figure 1 Schematic diagram of the structure of the auxiliary door opening mechanism. DETAILED DESCRIPTION

[0024] like Figure 1 As shown, a flood prevention and blocking device for a GCB room entrance comprises a vertical support body and a blocking door 3. The vertical support body is divided into a first vertical support body 1 and a second vertical support body 2. The first vertical support body 1 and the second vertical support body 2 are arranged parallel to each other. The blocking door 3 is connected to the first vertical support body 1 and the second vertical support body 2 on both sides of the lower end via a rotating shaft mechanism. Auxiliary door opening mechanisms are respectively provided on the outer sides of the first vertical support body 1 and the outer sides of the second vertical support body 2.

[0025] like Figure 3 As shown, the auxiliary door opening mechanism includes a cylindrical shell 4, a first connecting member 6, and a second connecting member; the lower end of the cylindrical shell 4 is closed and the upper end is open, and a spring 5 is provided inside the cylindrical shell 4; the first connecting member 6 is contact-connected with the top end of the spring 5 at the bottom end, and the first connecting member 6 is connected to one end of the second connecting member through the first rotating shaft 8 at the top end, and the other end of the second connecting member is contact-connected with one side of the blocking door 3, and the blocking door 3 is connected to the traction part of the traction device through a traction rope 10 in the middle and / or upper part.

[0026] The traction device can be a winch, which can be symmetrically arranged on the first vertical support body 1 and the second vertical support body 2 respectively. The traction rope 10 of the winch passes through multiple pulley guide assemblies in sequence and is connected to the middle or upper part of the blocking door 3 at the lower end. In order to realize the connection between the traction rope 10 and the blocking door 3 well, hanging ears can be symmetrically arranged on both sides of the middle or upper part of the blocking door 3.

[0027] The blocking door 3 is perpendicular to the horizontal plane in the normal state, i.e. the blocking state; due to the gravity of the blocking door 3 itself, the blocking door 3 applies a downward force to the spring 5 through the second connecting member and the first connecting member, so that the spring is in a compressed state; at this time, due to the influence of the gravity of the blocking door 3 itself, the blocking door 3 can intercept the flood.

[0028] The second connecting members in the auxiliary door opening mechanisms on both sides are respectively connected to the first vertical support body 1 and the second vertical support body 2 through the second rotating shaft 9. The second connecting member is composed of a first connecting arm and a second connecting arm.

[0029] In the extended state, the spring can drive the first connecting member 6 to make the first connecting member 6 move upward, thereby driving the second connecting member so that the second connecting long arm of the second connecting member applies an outward thrust to the blocking door 3.

[0030] The second connecting member is an integrally formed structural member.

[0031] The auxiliary door opening mechanism is vertically arranged and fixedly connected to the outer side of the vertical support body.

[0032] A through hole is opened on the cylinder wall of the cylinder shell 4, and a latch is provided in the through hole. When the blocking door 3 is in an upright state, the latch is horizontally inserted into the cylinder shell 4 through the through hole, and the end of the latch located inside the cylinder shell 4 is placed on the upper middle part of the spring 5 to limit the position of the spring 5 and prevent the spring 5 from stretching.

[0033] The first connecting wall is a short arm, and the free end of the first connecting arm is used to connect with the top of the first connecting member 6; the second connecting wall is a long arm, and the free end of the second connecting wall is used to be in contact connection with one side of the blocking door 3.

[0034] The vertical support body is arranged in the dam body 7, the GCB chamber is arranged on one side of the dam body 7, and the blocking door 3 is used to isolate flood water during the flood season.

[0035] Alternatively, the second connecting member is a V-shaped member formed by connecting the first connecting arm and the second connecting arm at the connecting ends.

[0036] When the utility model is used during flood prevention, the traction device drives the traction rope to lift the blocking door from a horizontal or inclined state to an upright state. At this time, on the one hand, after the blocking door is erected, the upward traction of the traction device and the gravity of the blocking door itself can effectively isolate the flood, preventing the flood from entering the dam and causing damage to the equipment in the GCB room. On the other hand, the latch is horizontally inserted into the cylinder shell 4 through the through hole, and the end of the latch located inside the cylinder shell 4 is placed on the middle and upper part of the spring 5 to limit the position of the spring 5 and prevent the spring 5 from stretching.

[0037] After the flood recedes, the traction device lowers the traction rope so that the traction rope is in a slightly relaxed state, and then the pin limiting the spring 5 is pulled out. This is because the spring 5 will give the first connecting member 6 in the auxiliary door opening mechanism an explosive lifting force under the action of its own elastic force. The explosive lifting force acts on the first connecting member 6 and is transmitted to the second connecting member. The part of the first connecting arm of the second connecting member close to the first connecting member 6 is suddenly tilted up, and the end of the second connecting arm close to the blocking door will suddenly provide an outward force to the blocking door, which can drive the blocking door to open outward. After the blocking door is opened, the blocking door is slowly lowered under the traction of the traction device and the traction rope. This can avoid the situation where the blocking door cannot be opened due to its own heavy weight.
