[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0027] Refer to Figure 1-Figure 3 As shown, there are two ways to arrange the existing power station trash rack, one is external and the other is internal, which is easy to accumulate dirt. When cleaning the dirt, it is usually necessary to use a special large-scale machine to clean the dirt or lift the trash rack to clean the dirt, which makes cleaning difficult; the use of the lifting type to clean the dirt is prone to the accumulation of dirt at the bottom, making it impossible for the trash rack to fall back to its original position. According to the above problems, the first embodiment of the present application provides a hydroelectric power station trash interception system, including a trash interception member 1 for intercepting dirt, the trash interception member 1 is installed inside the unit flow channel, downstream of the unit maintenance gate, the trash interception member 1 includes a trash rack installed inside the unit flow channel, the trash rack includes a grid surface 2 of a well structure and a support rod 3 supporting the grid surface 2, and the well structure design can effectively prevent dirt from entering the unit and add an extra guarantee for the unit to intercept dirt. An inlet 4 is opened on the grid surface 2, and the grid surface 2 and the support rod 3 are welded to the inside of the unit flow channel, and the support rod 3 increases the stability of the grid surface 2. The trash rack is installed inside the unit flow channel, and the advantage of the position enables the staff to clean the trash rack directly from the inside of the flow channel.
[0028] Refer to Figure 4-Figure 6As shown, the present application also provides a second embodiment, in which the trash-blocking member 1 is installed between the two side walls of the water inlet 51 of the power station and the plant, and the trash-blocking member 1 includes a shell 5, which is provided with a water inlet 51 and a water outlet 52, and a floating interception part 6 and a suspended interception part 7 are provided in the shell 5, wherein the floating interception part 6 is used to intercept floating garbage, and the suspended interception part 7 is used to intercept suspended garbage. The floating interception part 6 includes a fixed trash rack 61, and a clamping groove 53 is provided on the side wall of the shell 5, and the side wall of the fixed trash rack 61 is clamped with the clamping groove 53, and the bars on the fixed trash rack 61 can be provided with a plurality of grab hooks (not shown in the drawings) to facilitate the hooking of garbage.
[0029] The utility model also includes a movable trash rack 62 hinged to the fixed trash rack 61, and a plurality of grab hooks are also provided on the bars of the movable trash rack 62 (not shown in the attached drawings). The grab hooks on the fixed trash rack 61 and the movable trash rack 62 are flexible, and a guide rail 54 is provided on the side wall of the shell 5 corresponding to the movable track of the movable trash rack 62, so as to facilitate the movable trash rack 62 to move along a predetermined track. The first traction rope 8 is connected to both sides of the unhinged end of the movable trash rack 62, and the first traction rope 8 is connected to the winder. By starting the winder, the movable trash rack 62 is raised to form an angle collection cavity with the fixed trash rack 61 to prevent the floating garbage on the fixed trash rack 61 and the movable trash rack 62 from being detached, and then the floating garbage in the angle collection cavity is collected by a grabbing device, and the grabbing device is a grab bucket or a spiral recovery device, etc. (which belongs to the prior art and will not be elaborated here).
[0030] Refer to Figure 6 As shown, the suspended intercepting portion 7 includes an outer arc trash rack 71 and an inner arc trash rack 72. The bottom of the outer arc trash rack 71 abuts against the limiting groove of the bottom plate, the upper end of the outer arc trash rack 71 is connected to the limiting shell 73, the lower end of the inner arc trash rack 72 is connected to the limiting shell 73, the upper end of the inner arc trash rack 72 is fixedly connected to both sides of the shell 5, the upper end of the inner arc trash rack 72 is on the water surface and is provided with a dirt collecting member 11, and a reinforcing intercepting member 12 is obliquely provided at the bottom of the limiting shell 73. The limiting shell 73 adopts a fixed or adjustable type. The fixed type means that the inner arc trash rack 72 and the outer arc trash rack 71 are fixed to the side of the limiting shell 73, and the limiting shell 73 is fixed to the side wall of the shell 5. The position is fixed and the suspended intercepting portion 7 cannot be adjusted. The adjustable type is that the limit shell 73 is connected with a lifting member, and the lifting member can be a screw rod to drive the limit shell 73 to rise and fall, or a winding machine to achieve the limit rise and fall, thereby changing the vertical position of the limit shell 73, and the outer arc trash rack 71 is slidably connected to the limit shell 73. The outer arc trash rack 71 is used to intercept the bottom. Due to the shape of the outer arc trash rack 71, the water flow will prompt the bottom suspended garbage to move to the inner arc trash rack 72, reducing the accumulation of garbage in front of the outer arc trash rack 71. When sludge accumulates in front of the outer arc trash rack 71, it can be cleared through the mud cleaning member.
[0031] The upper end of the inner arc trash rack 72 is on the water surface, so that the inner arc trash rack 72 and the fixed trash rack 61 form a double-layer trash interception on the river surface. Because floating garbage has a great impact on the operation of the unit, and the floating garbage on the river water accounts for a large proportion, the floating garbage is intercepted to the greatest extent through double-layer trash interception. In order to collect the suspended garbage and the floating garbage that is not intercepted by the fixed trash rack 61 and the movable trash rack 62, a garbage collecting part 11 is provided at the upper end of the inner arc trash rack 72. The garbage collecting part 11 includes an inner arc plate trash rack, and the upper end is connected to the induction plate 111 through a flipping mechanism. The flipping mechanism is a winder traction rope (a winder traction rope is used in this figure) to achieve flipping or a flipping motor, and other existing mechanisms that can achieve flipping can be used (it belongs to the prior art and will not be elaborated here). The lower end surface of the induction plate 111 is symmetrically provided with two guide rods 112, and the guide rods 112 are provided with slide grooves, and the slide grooves are provided with sliders with through holes. The guide rods 112 are movably connected with telescopic sleeves 113, and the telescopic sleeves The tube 113 is connected to the second traction rope 13, and the slider is used to limit the direction of the second traction rope 13. The second traction rope 13 passes through the slider. The sensing plate 111 is connected to a winder. The upper end of the guide rod 112 and the bottom of the telescopic sleeve 113 are provided with clamps. Multiple clamps jointly hold open the collection net 114. The sensing plate 111 is provided with a weight sensor. When the sensing plate 111 detects that the collection net 114 is overweight, the winder starts to reel in the second traction rope 13, and the telescopic sleeve 113 is pushed upward. The telescopic sleeve 113 is similar to a bellows, which realizes that the opening of the collection net 114 becomes smaller to prevent the garbage in the collection net 114 from running out. The flipping mechanism is started to change the collection net 114 from horizontal to vertical, and then the garbage in the collection net 114 is cleaned or taken away by a grabbing device, and a new collection net 114 is reinstalled on multiple clamps to collect new garbage.
[0032] The reinforced interception member 12 comprises a plurality of groups of oblique rods 121, which are arranged at staggered positions and have a plurality of spikes 122 on the outer wall, so as to form a secondary interception for the garbage at the bottom.
[0033] Refer to Figure 7 , Figure 8 As shown, the present application also provides a third embodiment, which is basically the same as the second embodiment, with the only difference being that: the floating interception portion 6 also includes an upper rotating group 9 and a lower rotating group 10 rotatably connected to the fixed trash rack 61, a locking groove 53 is provided on the side wall of the shell 5, and the side wall of the fixed trash rack 61 is engaged with the locking groove 53, and a guide rail 54 is provided on the side wall of the shell 5 corresponding to the active trajectory of the upper rotating group 9, and the first traction rope 8 is connected to the unhinged two sides of the upper rotating group 9, and the first traction rope 8 is connected to the winder for pulling the upper rotating group 9 up to form an angle collection chamber with the fixed trash rack 61, and the lower rotating group 10 is configured with a driving member, and the driving member is used to drive the lower rotating group 10 to swing downward to form a preliminary interception for the suspended interception portion 7 and push the suspended garbage deposited in the suspended interception portion 7.
[0034] The upper rotating group 9 includes a fixed sleeve 91, and both sides of the fixed sleeve 91 are rotatably connected to the fixed trash rack 61. A plurality of first bars 92 are arranged at intervals on the fixed sleeve 91, and semicircular grooves 93 are opened between adjacent first bars 92. The lower rotating group 10 includes a rotating rod 101, and the rotating rod 101 transversely penetrates the fixed trash rack 61 and is arranged in the fixed sleeve 91. Second bars 102 are arranged at positions of the rotating rod 101 corresponding to the semicircular grooves 93, and there is a gap between the second bars 102 and the first bars 92. The upper end surfaces of the first bars 92 and the second bars 102 are provided with grab hooks. When the second bars 102 swing downward, the suspended garbage stuck on the human bars will be stuck on the first bars 92.
[0035] The above-mentioned specific improvement is as follows: the floating interception part 6 includes a fixed trash rack 61, an upper rotating group 9 and a lower rotating group 10 which are rotatably connected to the fixed trash rack 61, the upper rotating group 9 includes a fixed sleeve 91, both sides of the fixed sleeve 91 are rotatably connected to the fixed trash rack 61, a plurality of first bars 92 are arranged on the fixed sleeve at intervals, and semicircular grooves 93 are provided between adjacent first bars 92, the lower rotating group 10 includes a rotating rod 101, the rotating rod 101 horizontally penetrates the fixed trash rack 61 and is arranged in the fixed sleeve 91, The rotating rod 101 is provided with a second bar 102 at the position corresponding to the semicircular groove 93. There is a gap between the second bar 102 and the first bar 92 to facilitate the passage of water. The upper rotating group 9 is connected with the first traction rope 8. The first traction rope 8 is rolled up to form an angle collection chamber with the fixed trash rack 61. The lower rotating group 10 is equipped with a driving member, which is used to drive the rotating rod 101 to swing downward and then drive the second bar 102 to make a circular motion. The driving member is a synchronous belt drive or a chain drive to realize the rotation of the second bar 102. The second bar 102 will contact the upper end of the outer arc trash rack 71 and the inner arc trash rack 72, so that the second bar 102 plays a cleaning role when the upper end of the outer arc trash rack 71 and the inner arc trash rack 72 accumulate certain garbage and do not enter the collection net 114, thereby preventing garbage from accumulating. When the garbage collecting member 11 is processing the garbage in the collection net 114, the second bar 102 also preliminarily intercepts the subsequent garbage.
