Description

Technical Field

[0001] The utility model relates to the technical field of drift fences, and particularly to a drift fence device for a hydropower station. Background Art

[0002] Trash racks are usually arranged at the water inlet of the hydropower engineering unit to intercept the dirt in the reservoir area and prevent it from entering the water turbine generator set and causing equipment damage. However, due to the large amount of dirt, the trash racks are often blocked by dirt. If not cleaned in time, it will cause a decrease in the generating head, a reduction in the output of the unit, and a loss of power generation benefits in the light case; in the heavy case, it will damage the structure of the trash rack and even endanger the safe operation of the unit. In order to ensure the inlet flow condition and reduce the impact of dirt on the safe operation and normal power generation of the power station, a drift fence is usually additionally arranged in front of the dam or at the water inlet of the hydropower station and used in cooperation with the trash rack.

[0003] The floating barrels used in the existing technology for the drift fence are usually of an integral structure and are connected in series one by one. Its defects are as follows:

[0004] 1. Since there are gaps at the joints between the floating barrels in the existing technology, small dirt will still pass through these gaps with the water flow, resulting in low interception efficiency;

[0005] 2. Since the floating barrels in the existing technology are usually of an integral structure, when a certain floating barrel in the drift fence is damaged, the entire drift fence needs to be disassembled for replacement; this process is very time-consuming and laborious, especially for large drift fences or facilities placed in deep water, and the operation difficulty is very high;

[0006] 3. Since multiple floating barrels in the existing technology are connected in series by a single rope, and the floating barrels are prone to rotate under the flow of water, floating objects will leak from under the floating barrels, further reducing the interception efficiency. Summary of the Utility Model

[0007] Aiming at the above problems, the utility model provides a drift fence device for a hydropower station, aiming to effectively prevent floating objects from leaking through the gap between two floating barrels, improve the interception efficiency; enable each floating barrel to be independently installed and disassembled; greatly simplify the maintenance process, and greatly save maintenance time and labor costs; eliminate the problem that floating objects leak from under the floating barrels due to the rotation of the floating barrels in the existing technology.

[0008] To solve the above problems, the technical solution provided by the utility model is as follows:

[0009] A drift fence device for a hydropower station includes a plurality of floating barrels, a steel wire rope, an interception component, and a second interception net; wherein:

[0010] The steel wire rope passes through each of the floating barrels and connects all the floating barrels in series;

[0011] Both ends of the floating barrel are provided with snap columns;

[0012] Between two adjacent floating barrels, one second interception net is detachably connected through the snap columns; a plurality of through holes are formed through the surface of the second interception net, and it is arranged on the water-facing side of the floating debris interception device of this hydropower station.

[0013] Preferably, the floating barrel includes a first floating barrel and a second floating barrel; wherein:

[0015] The second interception net is detachably connected to the water-facing side of the snap column through a lock;

[0016] The second floating barrel is in a semi-barrel shape, and at least two second wire grooves are formed on the upper surface; the positions and shapes of the second wire grooves are matched with those of the first wire grooves;

[0017] The steel wire rope passes through between the first wire groove and the second wire groove to connect all the floating barrels in series.

[0018] Preferably, snap rings can be detachably connected to both the left and right sides at the bottom of the second floating barrel; the interception assembly is detachably connected to the second floating barrel through the snap rings.

[0019] Preferably, the interception assembly includes a connecting rod and a first interception net; wherein:

[0020] The connecting rod is clamped inside the snap ring; the first interception net is detachably connected to the bottom of the connecting rod;

[0021] A plurality of through holes are formed through the surface of the first interception net.

[0022] Preferably, at least three suspension ropes are detachably connected to the bottom of the first interception net;

[0023] The end of each suspension rope is detachably connected with a gravity ball.

[0024] Preferably, first notch openings are formed on both the front and rear sides of the first floating barrel; second notch openings are formed on both the front and rear sides of the second floating barrel; the positions and shapes of the first notch openings are matched with those of the second notch openings; the first floating barrel and the second floating barrel are detachably connected through a locking bolt

[0025] The locking bolt is arranged at the position where the first notch opening and the second notch opening intersect.

[0026] Preferably, at least two reflective strips are detachably connected to the surfaces of the first floating barrel and the second floating barrel.

[0027] Preferably, the first floating barrel is a hollow barrel;

[0028] The second floating barrel is a solid barrel.

[0029] Preferably, the number of the floating barrels is not less than five.

[0030] Compared with the prior art, the utility model has the following advantages:

[0031] 1. Since the utility model adds a second interception net between each adjacent floating barrel compared with the prior art, and the second interception net is arranged on the water-facing surface of the floating barrel, it can effectively prevent floating objects from leaking out through the gap between two floating barrels, thus improving the interception efficiency;

[0034] 4. Since the utility model uses a first wire groove and a second wire groove for threading to connect multiple floating barrels in series, it eliminates the problem that floating objects leak out from below the floating barrels due to the rotation of the floating barrels in the prior art;

[0035] 5. Since the utility model further sets an interception component to intercept suspended substances in the water body, compared with the prior art, the interception efficiency is significantly improved, ensuring that more suspended substances are effectively intercepted and preventing pollutants from entering the water turbine generator set and causing equipment damage.

[0042] The following further clarifies the present utility model in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. After reading the present utility model, various equivalent modifications made by those skilled in the art to the present utility model all fall within the scope defined by the appended claims of this application.

[0043] As Figures 1 to 4 shown, a floating debris barrier device for a hydropower station includes a plurality of floating barrels 1, a steel wire rope 2, an intercepting component 3, and a second intercepting net 4; wherein:

[0044] The steel wire rope 2 passes through each floating barrel 1 to connect all the floating barrels 1 in series.

[0045] Buckle posts 104 are provided at both ends of the floating barrel 1.

[0046] In this specific embodiment, the number of floating barrels 1 is not less than five.

[0047] In this specific embodiment, the floating barrel 1 includes a first floating barrel 101 and a second floating barrel 102; wherein:

[0048] The first floating barrel 101 is in a semi-barrel shape, and at least two first wire grooves 105 are transversely opened along the symmetry axis on the bottom surface; buckle posts 104 can be detachably connected to both the left and right ends of the first floating barrel 101.

[0049] The second intercepting net 4 is detachably connected to the water-facing side of the buckle post 104 through a lock 5.

[0050] The second floating barrel 102 is in a semi-barrel shape, and at least two second wire grooves 108 are opened on the upper surface; the positions and shapes of the second wire grooves 108 match those of the first wire grooves 105;

[0051] In this specific embodiment, buckle rings 107 can be detachably connected to both the left and right sides at the bottom of the second floating barrel 102; the intercepting component 3 is detachably connected to the second floating barrel 102 through the buckle rings 107.

[0052] It should be noted that the first wire groove 105 and the second wire groove 108 provide a stable passage for the wire rope 2, ensuring that the wire rope 2 is arranged neatly and orderly, avoiding swaying in the water flow, and improving the stability of the overall structure of the device.

[0053] The wire rope 2 passes through between the first wire groove 105 and the second wire groove 108, connecting all the floating barrels 1 in series.

[0054] Between two adjacent floating barrels 1, a second interception net 4 is detachably connected through a snap column 104; a number of through holes are formed through the surface of the second interception net 4, and it is arranged on the water-facing side of the floating debris interception and drainage device of this hydropower station.

[0055] In this specific embodiment, the second interception net 4 is made of stainless steel, is square in shape, and its size is customized according to the actual situation.

[0056] It should be noted that at least five floating barrels 1 are provided, and the second interception net 4 is arranged at the connection position of two floating barrels 1, further enhancing the interception effect on the basis of the existing technology and preventing floating objects from passing through the connection gap.

[0057] It should be further noted that the setting of at least five floating barrels 1 in this specific embodiment is only an example, and the specific quantity is determined according to the actual application environment. This specific embodiment does not limit the scope of the claims of this application.

[0058] In this specific embodiment, first notch openings 103 are provided on both the front and rear sides of the first floating barrel 101; second notch openings 106 are provided on both the front and rear sides of the second floating barrel 102; the positions and shapes of the first notch openings 103 and the second notch openings 106 are matched; the first floating barrel 101 and the second floating barrel 102 are detachably connected through a locking bolt 109.

[0059] The locking bolt 109 is arranged at the position where the first notch opening 103 and the second notch opening 106 intersect.

[0060] It should be noted that by tightly connecting the first floating barrel 101 and the second floating barrel 102 through the locking bolt 109, the stability between the two can be ensured to prevent separation under the impact of water flow.

[0061] In this specific embodiment, the first floating barrel 101 is a hollow barrel; the second floating barrel 102 is a solid barrel.

[0062] It should be noted that the first floating barrel 101 is designed to be hollow, which is beneficial to reducing the overall weight and increasing the buoyancy; the second floating barrel 102 is solid, so that the center of gravity of the device can be kept downward, increasing the stability of the device and preventing it from capsizing in strong water flow.

[0063] In this specific embodiment, at least two reflective strips 110 are detachably connected to the surfaces of the first floating barrel 101 and the second floating barrel 102.

[0064] It should be noted that in the night or low-light environment, the reflective strips 110 can reflect light, improve the visibility of the device, contribute to the avoidance of navigation vessels, and reduce the collision risk.

[0066] The connecting rod 301 is clamped inside the snap ring 107; the bottom of the connecting rod 301 is detachably connected with a first interception net 302.

[0067] A number of through holes are formed through the surface of the first interception net 302.

[0068] In this specific embodiment, at least three suspension ropes 303 are detachably connected to the bottom of the first interception net 302; the end of each suspension rope 303 is detachably connected with a gravity ball 304.

[0069] It should be noted that the gravity balls 304 are fixed to the bottom of the first interception net 302 through the suspension ropes 303, thereby increasing the vertical stability of the interception net, preventing floating under the action of water flow, and improving the interception efficiency.

[0070] The working principle of this device is as follows: The first floating barrel 101 and the second floating barrel 102 are fixed and connected by the locking bolts 109.

[0071] The floating barrels 1 adopt a split design; the advantage of the split design is that each floating barrel 1 can be independently installed and disassembled. When a certain floating barrel 1 needs to be replaced or repaired, only this specific unit needs to be processed, rather than removing the entire floating debris barrier row, which significantly simplifies the maintenance process and saves time and labor costs.

[0072] Furthermore, this application also adopts the first wire groove 105 and the second wire groove 108 to thread wires to connect multiple floating barrels 1 in series, which can prevent the floating barrels 1 from rotating and causing floating objects to leak from below the floating barrels 1; at the same time, a second interception net 4 is added, and the second interception net 4 is arranged on the water-facing side of the floating barrel 1, which can also effectively prevent floating objects from leaking from the gap between two floating barrels 1 and improve the interception efficiency.
