Detailed Description

The following specific embodiments are merely illustrative of the present invention, and are not intended to limit the present invention, and those skilled in the art can make modifications of the present embodiments without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws and protection within the scope of the present invention.

The scheme is realized by the following technical means:

example (b): in the embodiment, a scheme for automatically lifting the flood control wall is provided. Specifically, in the scheme, a hollow adjusting cavity 4a needs to be formed in the bank 1 close to the bank of the river where the flood condition is likely to occur, a baffle assembly 3 capable of moving up and down along the vertical direction is installed in the adjusting cavity 4a, and as the main body of the baffle assembly 3 moves upwards, the upper portion of the baffle assembly 3 moves upwards and protrudes relative to the upper surface of the bank 1; the adjusting cavity 4a extends towards one side of the river channel 2 to form a drainage channel 4b communicated with the river channel 2. Meanwhile, a floating block 4c with the integral density smaller than that of river water is arranged in the adjusting cavity 4a, for example, the floating block can be directly made of plastic materials or hollow structures made of other materials with lower density, and the upper surface of the floating block 4c is fixedly connected with the baffle plate component 3 to form the self-adaptive lifting mechanism 4.

When the river channel 2 has a flood situation, the water level of the river rises to enable river water to flow into the adjusting cavity 4a through the drainage channel 4b, and the floating blocks 4c can drive the baffle plate assemblies 3 fixedly connected and installed on the upper portion and the self to quickly rise and expand upwards under the buoyancy effect generated by the river water rushing into the adjusting cavity 4a, so that the work of the flood prevention wall is started. In consideration of the fact that the water level of the river channel 2 is always lifted up and down under the normal natural condition, if the water level floats in the normal range, the baffle plate assembly 3 is always driven to move up and down, the sealing layer structure on the surface of the inner baffle plate assembly 3 is easily abraded, aged or even damaged, and accordingly the flood prevention working effect of the device in the emergency situation is affected. Therefore, the one-way valve 5 device is arranged in the drainage channel 4b, and the one-way valve 5 is opened under a large enough pressure value through presetting, so that the one-way valve 5 is opened and the flood control wall is started to work by injecting water into the adjusting cavity 4a only when the water level of the river channel 2 reaches a certain warning height in the actual working process of control, thereby avoiding false triggering and damage and prolonging the service life of the device.

Further, considering that in the baffle plate assembly 3, different parts independently play roles, the baffle plate assembly 3 can be further divided into two parts, namely a baffle plate 3b for blocking contact with river water and a driving ejector rod 3a for supporting and driving. The blocking plate 3b is arranged on one side close to the river channel 2, the surface of the blocking plate is covered with a waterproof material layer, the driving ejector rod 3a is made of high-strength metal materials, the lower end part of the driving ejector rod is fixedly arranged on the floating block 4c, and the upper part of the driving ejector rod is fixedly connected with the upper end part of the blocking plate 3 b.

Furthermore, considering the production process difficulty and the cost control requirement of the plate 3b to be blocked, the blocking plate 3b can be further optimized to adopt a multi-section combined structure, the blocking plate 3b is formed by combining a plurality of baffle units 6 which are movably connected with each other, each baffle unit 6 is provided with a guide groove 6a used for being connected with the other baffle unit 6 on the upper side, and a connecting end 6b used for being connected with the other baffle unit 6 on the lower side. When the two baffle units 6 are connected and installed, the connecting end 6b is embedded in the guide groove 6a and can move along the extending direction of the guide groove 6 a; when the baffle plate unit 6 far away from one side of the river channel 2 is jacked up by the driving jacking rod 3a and drives the connecting end 6b to move to the top end relative to the guide groove 6a of the other adjacent baffle plate unit 6, the other adjacent baffle plate unit 6 is continuously driven to move upwards in a lifting manner, and the operation is circulated until all the baffle plate units 6 are sequentially lifted and unfolded, so that the whole starting work of the flood control wall is realized.

In the application of the barrier plate 3b with the multi-section combined structure, after each baffle plate unit 6 is unfolded, the stability of the fixed connection between the adjacent baffle plate units 6 is a remarkable problem, and if the baffle plate units are loosened and separated, the whole flood control wall which can be automatically lifted is collapsed, so that serious safety accidents can be caused. Therefore, an auxiliary stay 6c for supporting the other shutter unit 6 located on the upper side is also provided on the shutter unit 6. Specifically, an inner groove 601 for accommodating the auxiliary supporting piece 6c is formed in the back surface of the baffle unit 6 on the side close to the river channel 2, the auxiliary supporting piece 6c is installed in the inner groove 601, the lower baffle unit 6 of the auxiliary supporting piece 6c is connected in a hinged manner, and a driving spring 602 for driving the auxiliary supporting piece 6c to pop out is installed between the auxiliary supporting piece 6c and the wall surface of the inner groove 601. When the baffle assembly 3 is not deployed as a whole, the auxiliary abutment member 6c is stably confined in the inner groove 601 due to the blocking action of the front side surface of the adjacent rear baffle unit 6; and in case can rise the flood control wall automatically and start and be in when the expansion state, when baffle unit 6 that is located the rear side moved to the top and no longer played the effect of stopping to supplementary propping up piece 6c, supplementary propping up piece 6c can rotate and outwards pop out around doing the hinge center, realizes the reliable stable effect of propping up of baffle unit 6 that is located the top at this moment, has effectively promoted baffle subassembly 3's structural strength.

Further preferably, a water level height monitoring device is arranged at the upper part of the baffle plate component 3 and used for detecting the actual height of the water level so as to send out an alarm signal in time when the water level approaches the limit control height of the flood wall. Meanwhile, in order to improve the tightness between the two baffle units 6, a sealing material layer made of rubber can be arranged between the two baffle units 6 adjacent to each other up and down.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
