Description

Technical Field

[0001] The utility model relates to the field of column - type flood control devices, and specifically relates to a column - type flood control device. Background Technique

[0002] During the flood season, the water level rises rapidly. In the prior art, generally, a relatively high meter stick is set up at key flood control positions, and then inspectors observe the water level and the meter stick through a telescope to judge the current water level height during the flood season. After the observation, the inspection is carried out again. This method has low efficiency and is prone to errors. Later, a water level sensor was introduced to detect the water level during the flood season.

[0003] However, when using the water level sensor method, it is necessary to ensure that the water inlet of the sensor is unobstructed in the water to ensure effective liquid inlet and outlet. However, during the flood season, below the water level, the water situation is complex, and contaminants flowing with the water body are likely to enter the hollow column and cause errors in the water level sensor. Therefore, in the prior art, a porous protective net is added at the water inlet position to prevent impurities from entering the hollow column;

[0004] However, after the flexible contaminants below the water surface come into contact with the porous protective net, they are easily wound around the porous protective net, and there will still be a problem of poor water flow. Content of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a column-type flood control device includes a hollow column 2 with an outer shell 1 installed outside, an induction mechanism installed inside the outer shell 1, a first support plate 5 installed at the bottom of the outer shell 1, a steel column 6 welded on the first support plate 5, and a second support plate 7 welded at the bottom of the steel column 6. There is an installation interlayer between the first support plate 5 and the second support plate 7;

[0023] A protection mechanism is arranged between the installation interlayers. The protection mechanism is used to prevent impurities from entering the inside of the hollow column 2 and ensure the smooth flow of water in the hollow column 2;

[0024] The induction mechanism is used to implement the induction of the water level height.

[0025] In this embodiment: In flood control work, the implementation water level at important positions is very important for flood control work. When the water level rises, the water body enters the hollow column 2 through the liquid inlet 10 of the hollow column 2 and contacts the induction mechanism. The induction mechanism rises and falls with the water level and transmits the real-time water level to the terminal, and the flood control headquarters can know the real-time water level at important positions;

[0026] When the water level rises and the water flows towards the low water level position, at the junction where the flowing water body contacts the protection mechanism, and the dirt in the water body is intercepted by the protection mechanism. At the same time, the flowing water body drives the protection mechanism to rotate, so as to prevent the flexible dirt from winding around the protection mechanism and prevent the dirt from entering the inside of the hollow column 2, resulting in the problem of inaccurate induction caused by the up and down sliding of the induction mechanism under other forces.

[0027] Please refer specifically to Figure 4 , the induction mechanism includes: a vertical track groove 3, a guide rod 13, a floating plate 14 and a reed switch 16;

[0028] An outwardly protruding vertical track groove 3 is formed on the inner peripheral surface of the inner cavity of the hollow column 2; the guide rod 13 is fixedly connected to the top end of the inner wall of the hollow column 2 and extends downward. An anti-separation part is formed at the bottom end of the guide rod 13, and the diameter of the anti-separation part is larger than that of the guide rod 13. The anti-separation part is used to prevent the floating plate 14 from separating from the guide rod 13; a floating plate 14 is slidably connected to the outer wall of the guide rod 13 up and down. A magnet 15 is formed on the outer periphery of the floating plate 14 and is slidably connected to the inner cavity of the vertical track groove 3 up and down. A plurality of reed switches 16 are installed in the inner cavity of the vertical track groove 3 in the vertical direction, and the plurality of reed switches 16 are equally spaced in the vertical direction; a conductive connection head 4 is installed at the top end of the vertical track groove 3, and the conductive connection head 4 is electrically connected to the reed switch 16. The reed switch 16 is electrically connected to the terminal through a wire and an electrical connection head 4.

[0029] In this embodiment: when the water level rises, the floating plate 14 is always flush with the water level surface due to buoyancy. Therefore, when the water level rises, the floating plate 14 moves upward along the outer wall of the guide rod 13. The floating plate 14 drives the magnet 15 to slide upward along the outer wall of the vertical track groove 3. During this process, the vertical track groove 3 limits the sliding of the magnet 15.

[0030] When the magnet 15 moves to a certain position and aligns with the reed switch 16 at that position, under the action of the magnetic field, the two iron sheets inside the reed switch 16 are adsorbed and fitted under the action of magnetic force. At this time, the circuit is turned on and an electrical signal is generated. The electrical signal is transmitted to the terminal through the conductive connection head 4 and the wire. The terminal can judge the water level height through the corresponding electrical signal (for example: reed switches 16 at different heights are connected to different pins of the terminal through wires, and different pins are electrically connected to corresponding warning lights, and the water level height can be judged through the corresponding warning lights).

[0031] Please refer specifically to Figure 2, the protection mechanism includes a lower protection net 9 arranged at the top of the second support plate 7 and an upper protection net 8 arranged at the bottom of the first support plate 5. The top end of the lower protection net 9 is integrally formed with the bottom end of the upper protection net 8. The top end of the upper protection net 8 is in contact with the bottom end of the first support plate 5, and the bottom end of the lower protection net 9 is in contact with the top end of the second support plate 7. The protection mechanism further includes a rotating shaft 11 rotatably connected to the center of the top end of the second support plate 7. An impeller 12 is press-fitted on the outer wall of the rotating shaft 11, and the top end of the rotating shaft 11 is fixedly connected to the center of the bottom end of the upper protection net 8.

[0032] In this embodiment: at high water levels, water flows towards lower water levels or low-lying areas. The flowing water drives the impeller 12 to rotate. The impeller 12 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the upper protection net 8 to rotate synchronously. The upper protection net 8 drives the lower protection net 9 to rotate synchronously.

[0033] Therefore, after the dirt flowing with the water contacts the upper protection net 8 and the lower protection net 9, especially the relatively flexible dirt (such as: leaves or plastic bags sinking in the water), when the protection mechanism rotates, the side of the dirt in contact with the protection mechanism will be collected by the water flow, and thus it will flow with the water. Moreover, the surfaces of the upper protection net 8 and the lower protection net 9 of the protection mechanism are smooth without protrusions, and it is not easy to cause a snagging phenomenon when contacting the flexible dirt, thereby avoiding the problem of clogging the upper protection net 8 and the lower protection net 9, and at the same time, it can also prevent dirt from entering the hollow column 2.

[0034] Please refer specifically to Figure 2 and Figure 4 , the liquid inlet 10 at the bottom end of the hollow column 2 penetrates below the first support plate 5 and is located inside the cavity of the upper protection net 8.

[0035] The outer diameter of the floating plate 14 is smaller than the inner diameter of the hollow column 2.

[0036] In this embodiment: after the water enters the hollow column 2 through the liquid inlet 10, the liquid level inside the hollow column 2 is flush with the external liquid level.

[0037] When the floating plate 14 moves up and down, the friction force on the floating plate 14 is relatively small, which is more convenient for the up and down movement of the floating plate 14.

[0038] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
