[0002] In drinking water systems such as reservoirs, fish intercepting devices need to be installed at water intakes to block and drive fish away from the water intakes. Current fish intercepting devices include fishing nets, electric fences, and bamboo and wooden fences. Compared with traditional fish intercepting methods such as fishing nets and bamboo and wooden fences, electric fences have the advantages of low cost, high interception efficiency, and less manpower investment.

[0003] Electric fences are devices that block fish and are usually composed of electrodes and pulse generators. Metal tubes are erected in the water in a single or double row with a certain distance between the electrodes to form an electric field to prevent fish from escaping.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] like Figure 1-Figure 9 As shown, a fish blocking device at a water intake according to an embodiment of the present invention comprises two support columns 1, a guide rod No. 2 and a plurality of electric grids 3, wherein the guide rod No. 2 is installed between the two support columns 1, and the plurality of electric grids 3 are evenly distributed on the guide rod No. 2. When the electric grids 3 are energized, an electric field is formed to prevent fish from approaching, and the device further comprises: an interception component 4 installed on the guide rod No. 2, wherein the interception component 4 is used for a screen frame 46 for blocking animal carcasses and a monitoring component 45 for observing animal carcasses.

[0034] Specifically, due to factors such as weather changes, blind release of fish, and toxic algae, there may be dead fish in water bodies such as reservoirs. These dead fish float in the water and are not affected by the electric field. Since the electrodes are in the form of vertical metal tubes, there is a situation where the dead fish pass through the electric grid 3 to the water intake without obstruction. Figure 1The two support rods 47 are located on the left and right sides, and the monitoring mechanism 45 is made of waterproof material. The monitoring mechanism 45 adopts the existing structure of shooting through a camera, feeding back the shooting results to the controller, and controlling the movement of parts through the controller; before work, the support column 1 is respectively erected on both sides of the river or reservoir. During work, the electric grid 3 is energized. After energization, an electric field is formed between each electric grid 3. When live fish approach, they will feel the stimulation of the current, so that the live fish stay away from the water intake, and the effect of intercepting live fish can be achieved. When the monitoring mechanism 45 captures a dead fish about to float on the water surface or a dead fish underwater about to float up, the screen frame 46 is controlled to move to the rear of the dead fish, and the dead fish is waited to move into the screen frame 46, so as to intercept the dead fish; by setting the interception component 4, the dead fish are intercepted, which improves the problem that the dead fish pass through the electric grid 3 and affect the water intake of the water intake.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the interception assembly 4 includes: a number of No. 1 connecting rods 41 slidably mounted on the No. 1 guide rod 2, the No. 1 connecting rod 41 and the electric grid 3 are alternately distributed on the No. 1 guide rod 2; a connecting plate 42 rotatably mounted under the No. 1 connecting rod 41; two screw rods 43 rotatably mounted on the connecting plate 42; a No. 2 connecting rod 44 mounted on the screw rod 43, the screen frame 46 is mounted on the two No. 2 connecting rods 44, and the monitoring mechanism 45 is mounted on the No. 2 connecting rod 44.

[0036] Specifically, in the initial state, the screen frame 46 is located above the water surface. When the monitoring mechanism 45 captures a dead fish about to float on the water surface or a dead fish underwater about to float up, the No. 1 connecting rod 41 is controlled to slide left and right relative to the No. 1 guide rod 2, and the screw rod 43 is controlled to rotate so that the No. 2 connecting rod 44 and the screen frame 46 are synchronously moved downward until the middle of the screen frame 46 is at the same height as the dead fish. The No. 1 connecting rod 41 slides left and right to drive the screen frame 46 to move left and right synchronously until the screen frame 46 is located behind the dead fish. After waiting for the dead fish to move into the screen frame 46, the screw rod 43 is controlled to rotate so that the No. 2 connecting rod 44 and the screen frame 46 move upward until the screen frame 46 drives the dead fish out of the water, thereby realizing the action of intercepting the dead fish. Compared with the method of intercepting with the entire fishing net, the method of the present invention can bring the dead fish out of the water, improves the problem that the dead fish are stuck in the fishing net or float outside the fishing net, and the decomposition of the dead fish affects the water quality at the water intake, and is convenient for the staff to take it away.

[0037] like Figure 1 , Figure 3 and Figure 4As shown, it also includes: a No. 2 guide rod 5 installed on the support column 1; an ejection mechanism 6 slidably installed on the No. 2 guide rod 5, a guide tube 7 is fixedly installed below the ejection mechanism 6, and the ejection mechanism 6 can be connected with the screen frame 46 through the guide tube 7, and the ejection mechanism 6 includes: a box 61 for accommodating dead fish, the box 61 is connected to the guide tube, and the side wall and the lower end of the box 61 are equipped with a rotating door, and the door of the side wall is used for the dead fish to go out of the box 61; a push plate 62 slidably installed in the box 61, and a push plate 62 is installed between the push plate 62 and the box 61 There is a No. 2 spring 63; a rotating rod 64 rotatably installed in the box body 61, the rotating rod 64 is threadedly connected to the push plate 62, and an impeller 65 is installed at one end of the rotating rod 64; a No. 1 ratchet 66 installed at one end of the rotating rod 64; a No. 1 check block 67 slidably installed on the box body 61, the No. 1 check block 67 is used to limit the unidirectional rotation of the No. 1 ratchet 66, and a No. 3 spring 68 is installed between the No. 1 check block 67 and the box body 61; a fixed rod 69 fixedly installed on the No. 2 guide rod, and the fixed rod 69 is located within the moving range of the No. 1 check block 67.

[0038] Specifically, the fixing rod 69 is arranged at a position where the second guide rod 5 is close to the shore, a suction pump is arranged in the ejection mechanism 6, and one or two ejection mechanisms 6 can be designed according to the demand, and the feed port of the conduit 7 is located below the water surface. Restricted by the first check block 67, the first ratchet 66 can only rotate clockwise (in Figure 4For example), in daily use, when the impeller 65 is blown by the wind from front to back, it can drive the rotating rod 64 and the No. 1 ratchet 66 to rotate clockwise. The clockwise rotation of the No. 1 ratchet 66 causes the push plate 62 to move from left to right, so that the No. 2 spring 63 is compressed. During operation, after the dead fish is intercepted in the screen frame 46, the screw rod 43 is controlled to rotate so that the screen frame 46 and the dead fish move upward until the screen frame 46 and the conduit 7 are at the same level, and then the ejection mechanism 6 and the conduit 7 are controlled to move left and right until the conduit 7 is aligned with the screen frame 46, and then the door at the lower end of the box 61 of the ejection mechanism 6 is controlled to open, and the suction pump is controlled to work, so that the dead fish in the screen frame 46 are sucked into the box 61 through the conduit 7, and then the door at the lower end of the box 61 is closed. The box body 61 and the dead fish are moved to the left. During the movement, the No. 1 check block 67 contacts the fixed rod 69. Since the fixed rod 69 remains stationary, the No. 1 check block 67 is pushed to the right until the No. 1 check block 67 is no longer in contact with the No. 1 ratchet 66. At this time, the No. 3 spring 68 is compressed, and the push plate 62 is pushed by the No. 2 spring 63 to slide to the left. The push plate 62 slides and pushes the dead fish to move synchronously until the dead fish is ejected from the box body 61 and falls on the shore. Then the box body 61 is controlled to move to the right until the No. 1 check block 67 is engaged with the No. 1 ratchet 66 again under the action of the elastic force of the No. 3 spring 68, thus completing the action of ejecting the dead fish to the shore. There is no need to manually handle the dead fish in the screen frame 46, and it is easy to use.

[0039] like Figure 5 As shown, the screen frame 46 adopts a folding structure, and a support rod 47 is slidably installed on the screen frame 46. After the support rod 47 slides downward out of the interior of the screen frame 46, the screen frame 46 is folded, and after the support rod 47 slides upward to the interior of the screen frame 46, the screen frame 46 is opened.

[0040] Specifically, in the initial state, the screen frame 46 is in a folded state, and the screen frame 46 is located in the water. After the monitoring mechanism 45 photographs the dead fish, the support rod 47 is controlled to move upward relative to the screen frame 46, so that the support rod 47 is inserted into the interior of the screen frame 46, so that the screen frame 46 is opened, and then the screen frame 46 is controlled to intercept the dead fish; the screen frame 46 is provided with a foldable structure, and when not in use, it is in a folded state, which reduces the contact area between the screen frame 46 and the water flow, and reduces the impact of the flowing water on the screen frame 46, the screw rod 43 and the No. 1 guide rod 2 toward the water intake, so as to extend the service life of the No. 1 guide rod 2. At the same time, the screen frame 46 is in a folded state, which can prevent algae and the like from drifting into the screen frame 46. Under the action of long-term, the screen frame 46 is blocked, affecting the interception effect.

[0041] like Figure 2 and Figure 5As shown, the interception assembly 4 also includes: a No. 1 spring 48 fixedly installed between the screen frame 46 and the support rod 47; a baffle 49 fixedly installed on the connecting plate 42, and the baffle 49 is used to prevent the support rod 47 from moving upward together with the screen frame 46.

[0042] Specifically, in the initial state, the screen frame 46 is in a folded state, and the No. 1 spring 48 is in a stretched state. When work is needed, the No. 2 connecting rod 44 and the screen frame 46 are controlled to move downward, and the support rod 47 moves upward under the action of the elastic force of the No. 1 spring 48 and is inserted into the interior of the screen frame 46, so that the screen frame 46 moves downward and unfolds at the same time. After the work is completed, the No. 2 connecting rod 44 and the screen frame 46 are controlled to move upward. During the movement, the support rod 47 contacts with the baffle 49 and is blocked by the baffle 49. The support rod 47 remains stationary, while the screen frame 46 continues to move upward. Therefore, the support rod 47 moves out from the interior of the screen frame 46, so that the screen frame 46 is folded under the action of gravity. At this time, the No. 1 spring 48 is stretched, and there is no need to set up an additional device to drive the screen frame 46 to unfold and fold, which is easy to use.

[0043] like Figure 6 As shown, the interception assembly 4 also includes a fan blade 410 fixedly and rotatably mounted on the side wall of the screen frame 46 , and the other side of the fan blade 410 is covered with a screen plate. The rotation of the fan blade 410 can cause water to flow into the screen frame 46 .

[0044] Specifically, by setting the fan blades 410, during the operation, the fan blades 410 are controlled to rotate so that water flows into the screen frame 46 from the entrance and flows out from the fan blades 410, so that the screen frame 46 is near the dead fish, and the dead fish can be introduced into the screen frame 46, and it is ensured that the dead fish will not move from the screen frame 46 during the movement. At the same time, the speed at which the dead fish enter the screen frame 46 can be accelerated.

[0045] like Figure 5 and Figure 6 As shown, the interception assembly 4 also includes: a slide bar 9 which is slidably installed above the screen frame 46, and the support rod 47 is movably connected to the slide bar 9; a switch No. 1 412 installed on the slide bar 9, and the switch No. 1 412 is inserted into the interior of the screen frame 46 through the holes of the screen frame 46, and the holes on both sides of the screen frame 46 are aligned, and the switch No. 1 412 is used to control the alignment of the screen frame 46 and the conduit 7, and the ejection mechanism 6 works again.

[0046] Specifically, the contact surface of the insertion rod 411 and the support rod 47 is a rough surface. When the support rod 47 slides out of the screen frame 46, the support rod 47 moves downward to drive the insertion rod 411 to move downward. The insertion rod 411 moves downward so that the switch No. 1 412 is inserted into the screen frame 46. After the insertion rod 411 contacts the upper surface of the screen frame 46, the insertion rod 411 drives the upper part of the screen frame 46 to move downward synchronously, so that the screen frame 46 is folded. At this time, the upper and lower parts of the screen frame 46 and the support rod 47 continue to move until the support rod 47 moves out of the insertion rod 411. After the screen frame 46 is folded, if there is no dead fish in the screen frame 46, the switch No. 1 412 is inserted into the hole below the screen frame 46. If there are dead fish in the sieve frame 46, switch No. 1 412 is triggered. After switch No. 1 412 is triggered, the sieve frame 46 is controlled to unfold and align with the guide tube 7 of the ejection mechanism 6 again, and the ejection mechanism 6 is controlled to perform suction and crushing work again to avoid the dead fish not being sucked away by the ejection mechanism 6. When the sieve frame 46 is unfolded, the support rod 47 is inserted into the sieve frame 46, and the insertion rod 411 is first pushed to move upward relative to the sieve frame 46, driving the switch No. 1 412 to move upward synchronously until the switch No. 1 412 moves out of the interior of the sieve frame 46, and the support rod 47 is connected with the insertion rod 411, and the upper part of the sieve frame 46 is pushed upward relative to the lower part of the sieve frame 46 through the insertion rod 411, so that the sieve frame 46 is unfolded.

[0047] like Figure 3-Figure 7 As shown, the interception assembly 4 also includes: a warning light 413 installed on the ejection mechanism 6; a No. 2 ratchet 414 rotatably installed on the No. 2 connecting rod 44, a torsion spring is installed between the No. 2 ratchet 414 and the No. 2 connecting rod 44; a No. 2 switch 415 fixedly installed on the No. 2 connecting rod 44, the No. 2 switch 415 is located within the moving range of the No. 2 ratchet 414, and the No. 2 switch 415 can control the start of the warning light 413 after being triggered; a pawl 416 rotatably installed on the support rod 47, the pawl 416 is used to push the No. 2 ratchet 414 to rotate; a telescopic rod 417 fixedly installed on the No. 2 connecting rod 44, a No. 2 check block 418 is fixedly installed on the upper part of the telescopic rod 417, and the No. 2 check block 418 is used to limit the unidirectional rotation of the No. 2 ratchet 414.

[0048] Specifically, the telescopic rod 417 is intermittently reciprocated up and down to Figure 6For example, the second ratchet 414 is restricted by the second check block 418 and can only rotate counterclockwise. When the support rod 47 moves downward relative to the screen frame 46, the pawl 416 is driven to move downward synchronously. The downward movement of the pawl 416 can push the second ratchet 414 to rotate counterclockwise. The counterclockwise rotation of the second ratchet 414 causes the torsion spring to twist. Since the telescopic rod 417 reciprocates up and down intermittently, the second check block 418 moves up and down intermittently. When the second check block 418 is not in contact with the second ratchet 414, the second ratchet 414 can rotate a part of the angle under the action of the torsion spring elastic force. If the probability of dead fish appearing is low and the spring is If the ejection mechanism 6 is normal, the telescopic rod 417 can move back and forth multiple times when the support rod 47 is not working, and the No. 2 ratchet 414 returns to its original state under the action of the torsion spring force. If the probability of dead fish appearing is high or there is a problem with the ejection mechanism 6, when the No. 2 ratchet 414 has not returned to its original state, the telescopic rod 417 moves downward again, and the pawl 416 pushes the No. 2 ratchet 414 to rotate counterclockwise again, and this accumulates until the No. 2 ratchet 414 contacts the No. 2 switch 415. After the No. 2 switch 415 is triggered, the warning light 413 can be controlled to light up, and an abnormal signal can be sent to the staff to quickly troubleshoot the problem.

[0049] like Figure 1 and Figure 8 As shown, a rangefinder 8 and a slide bar 9 are fixedly mounted on the guide bar No. 1 2, a floating body 10 is slidably mounted on the slide bar 9, the guide bar No. 1 2 and the guide bar No. 2 5 are both slidably connected to the support column 1 up and down, and the rangefinder 8 adjusts the positions of the guide bar No. 2 5 and the guide bar No. 1 2 on the support column 1 by measuring the distance between the guide bar No. 1 and the floating body 10.

[0050] Specifically, the floating body 10 is made of foam, rubber or other materials that can float on the water surface. It is located below the rangefinder 8. When in use, the rangefinder 8 measures the distance between it and the floating body 10, and controls the No. 1 guide rod 2 and the No. 2 guide rod 5 to move up and down relative to the support column 1 according to the size of the distance, so that the interception component 4, the ejection mechanism 6 and the electric grid 3 can adjust their height according to the height of the water level, which is more practical.

[0051] like Figure 8 and Fig. 9 As shown, it also includes: a No. 1 connecting rope 11 passing through a number of the No. 1 connecting rods 41 and the electric grid 3, and the No. 1 connecting rope 11 is slidably connected to the No. 1 connecting rod 41 and the electric grid 3; a fixed column 12 placed on one side of the support column 1; a floating board 14, and a No. 2 connecting rope 13 is fixedly installed on the floating board 14, and the No. 2 connecting rope 13 passes through the fixed column 12 and is connected to the No. 1 connecting rope 11.

[0052] Specifically, when a flood occurs, the water flow velocity in the reservoir increases, and the impact force on the interception assembly 4 and the electric grid 3 increases, so that the probability of the No. 1 guide rod 2 breaking increases; Figure 7 In the figure, assuming that the water flows from front to back, the floating plate 14 is located in the water surface and receives the impact of the water. The floating plate 14 generates a backward force. Therefore, the No. 2 pull rope in front is pulled by the floating plate 14, which generates a forward force on the No. 1 pull rope, so as to reduce the backward force on the interception component 4 and the electric grid 3 on the No. 1 pull rope, reduce the probability of the No. 1 guide rod 2 breaking, and extend the service life of the device.

[0053] Working principle: before working, the support column 1 is respectively set up on both sides of the river or reservoir. When working, the electric fence 3 is energized, and an electric field is formed between the electric fences 3 after energization. When the live fish approach, they will feel the stimulation of the current, so that the live fish will stay away from the water intake, and the effect of intercepting the live fish can be achieved. When the monitoring mechanism 45 captures the dead fish about to float on the water surface or the dead fish underwater about to float up, the No. 1 connecting rod 41 is controlled to slide left and right relative to the No. 1 guide rod 2, and the screw rod 43 is controlled to rotate so that the No. 2 connecting rod 44 and the screen frame 46 are synchronously moved downward until the screen frame 46 is The middle part is at the same height as the dead fish, the No. 1 connecting rod 41 slides left and right to drive the screen frame 46 to move left and right synchronously until the screen frame 46 is located behind the dead fish, and after the dead fish moves into the screen frame 46, the screw rod 43 is controlled to rotate, so that the No. 2 connecting rod 44 and the screen frame 46 move upward, until the screen frame 46 drives the dead fish to move out of the water, and the action of intercepting the dead fish can be achieved. In daily use, when the impeller 65 is blown from front to back by the wind, it can drive the rotating rod 64 and the No. 1 ratchet 66 to rotate clockwise, and the No. 1 ratchet 66 rotates clockwise to move the push plate 62 from left to right, so that The second spring 63 is compressed. When working, after the dead fish is intercepted in the screen frame 46, the screw rod 43 is controlled to rotate, so that the screen frame 46 and the dead fish move upward until the screen frame 46 and the guide tube 7 are at the same level. Then the ejection mechanism 6 and the guide tube 7 are controlled to move left and right until the guide tube 7 is aligned with the screen frame 46. Then the door at the lower end of the box 61 of the ejection mechanism 6 is controlled to open, and the suction pump is controlled to work to suck the dead fish in the screen frame 46 into the box 61 through the guide tube 7. Then the door at the lower end of the box 61 is closed, and the box 61 and the dead fish are moved to the left. During the movement, the first check valve is Block 67 contacts with the fixed rod 69. Since the fixed rod 69 remains stationary, the No. 1 check block 67 is pushed to the right until the No. 1 check block 67 is no longer in contact with the No. 1 ratchet 66. At this time, the No. 3 spring 68 is compressed, and the push plate 62 is pushed by the No. 2 spring 63 to slide to the left. The push plate 62 slides and pushes the dead fish to move synchronously until the dead fish is ejected from the box 61 and falls on the shore. Then the box 61 is controlled to move to the right until the No. 1 check block 67 is engaged with the No. 1 ratchet 66 again under the action of the elastic force of the No. 3 spring 68, thus completing the action of ejecting the dead fish to the shore.
