[0039] Example

[0040] like Figure 1-7 As shown, this embodiment provides a folding lifting fish barrier electric grid, which includes a mounting column 1, an electrode mounting mechanism 2, a traction device 3, a traction cable 4, a pulley 5, a flexible insulating connector 6, an electrode 7, an electrode counterweight 8, and an annular guide cable buckle 9.

[0041] The structural arrangement of the folding lifting fish barrier provided in this embodiment is described below. The folding lifting fish barrier provided in this embodiment includes two mounting columns 1, which are symmetrically arranged on both sides of the river channel and fixedly connected to the civil engineering structure.

[0042] The electrode mounting mechanism 2 is connected at both ends to the mounting columns 1 on both sides of the river channel. The electrode mounting mechanism 2 is connected to several electrodes 7, which are connected to the electrode mounting mechanism 2 and extend towards the bottom of the river channel. The electrodes 7 can rotate around their connection points with the electrode mounting mechanism, and are arranged along the electrode mounting mechanism to form a fish-blocking electric grid. Regarding the specific structure of the electrodes 7, they can be rigid or flexible; this embodiment does not limit this. Furthermore, the fish-blocking electric grid is divided into a left grid group and a right grid group, with the river channel centerline as the boundary. The left and right grid groups are arranged in opposite planes, respectively, in two staggered planes to avoid interference between the electrodes 7 when the fish-blocking electric grid is folded.

[0043] In this embodiment, the electrode mounting mechanism 2 is a motor mounting mechanism used to connect the electrodes 7. Regarding the structure of the electrode mounting mechanism 2, this embodiment selects a steel truss structure to enhance structural stability. However, in other embodiments, other types of electrode mounting mechanisms can be used: a steel plate beam structure, a steel cable structure, or an existing pedestrian bridge can be directly used as the electrode mounting foundation. Furthermore, the electrode mounting mechanism 2 is movably connected to several electrodes 7 via flexible insulating connectors 6, allowing the electrodes 7 to swing at a certain angle. The flexible insulating connectors 6 enhance the electrical safety of the grid while also ensuring the mobility of the electrodes 7.

[0044] The left and right electric grid groups of the electrode mounting mechanism 2 are each equipped with a traction cable 4. One end of the traction cable 4 is connected to the traction device 3, which acts as the traction device to wind and unwind the traction cable 4. The other end is fixedly connected to the electrode 7 connected to the left or right electric grid group. In this embodiment, a traction winch is selected as the traction device 3, but in other embodiments, other traction devices can also be used. Furthermore, when the traction device 3 winds up the traction cable 4, the traction cable 4 can pull all the electrodes 7 fixedly connected to it, causing the connection point between the traction cable 4 and the electrode 7 to move towards the electrode mounting mechanism 2 until it leaves the river surface. Since the electrode 7 is relatively long, if it is stored on this side of the riverbank, it will often interfere with the riverbank buildings. Therefore, the electrode 7 of the left electric grid group moves to the right and the electrode 7 of the right electric grid group moves to the left. That is, the electrodes 7 of both the left and right electric grid groups are folded and lifted towards the opposite bank to make full use of the upper space of the river on the other side. The traction cable 4 is preferably made of insulating material to prevent safety hazards caused by changes in water level.

[0045] The traction device 3, serving as the traction device for the traction cable 4, can be installed only on one side of the river channel, such as on the mounting column 1 on a single side of the river channel, to uniformly control the folding of the left and right electric grid groups. In this embodiment, traction devices 3 are installed on both sides of the river channel, such as on the mounting columns 1 on both sides of the river channel. The traction device 3 on the left side of the river channel is used to control the folding of the right electric grid group, and the traction device 3 on the right side of the river channel is used to control the folding of the left electric grid group. The two traction devices independently control the folding of the two electric grid groups, improving the stability of the electric grid folding traction.

[0046] Furthermore, the electrode mounting mechanism 2 is equipped with pulleys 5 and several annular guide buckles 9. One end of the traction cable 4 is connected to the traction device 3, and the other end is limited and guided by the annular guide buckles 9. After passing through the traction part, it is turned by the pulleys 5 and connected to each electrode 7 of the left or right electric grid group. Given that the traction cable 4 has a certain length, the function of the annular guide buckles 9 is to limit the position of the traction cable 4 and prevent the traction cable 4 from sagging or swaying in the wind due to gravity or other reasons. In addition to the annular guide buckles 9 in this embodiment, guide buckles of other shapes or structures can also be used to achieve a similar purpose. The pulleys 5 enable the traction cable 4 to achieve stable turning, so that the winding tension of the traction device can be better transmitted to the electrode 7, thereby enhancing the stability of the winding and unwinding process.

[0047] Furthermore, a hanging device is provided on the mounting column 1. The hanging device includes a cantilever beam extending towards the opposite bank, and the cantilever beam is connected to the electrode mounting mechanism 2. One end of the electrode mounting mechanism 2 is rotatably connected to the mounting column 1, and the other end is not connected to the mounting column 1 or is detachably connected to the mounting column 1. This allows the electrode mounting mechanism 2 to be placed against the riverbank under the action of the hanging device. That is, driven by the hanging device, the cantilever beam pulls the electrode mounting mechanism 2 to rotate about the mounting column 1 as an axis, causing the electrode mounting mechanism 2 to perform planar rotational movement until it is close to the riverbank.

[0048] In this embodiment, the electrode mounting mechanism 2 further includes a left-side electrode frame 21 and a right-side electrode frame 22 arranged independently on opposite sides. That is, the left-side electrode frame 21 and the right-side electrode frame 22 are not located in the same plane, but are situated in two staggered planes. Both ends of the left-side electrode frame 21 and the right-side electrode frame 22 are connected to the mounting columns 1 on both sides of the river channel. Both the left-side electrode frame 21 and the right-side electrode frame 22 consist of a traction part and an electrode connection part. The left-side electrode frame 21 connects to the right electrode group, and the right-side electrode frame 22 connects to the left electrode group. The traction part of the left-side electrode frame 21 connects to the left mounting column 1, and the electrode connection part connects to the right mounting column 1; the traction part of the right-side electrode frame 22 connects to the right mounting column 1, and the electrode connection part connects to the left mounting column 1. It should be noted that in other embodiments, the left-side electrode frame 21 can also connect to the left electrode group, and the right-side electrode frame 22 can be used to connect to the right electrode group.

[0049] Furthermore, in this embodiment, the left electric grid frame 21 and the right electric grid frame 22 are each independently equipped with a traction cable 4, and the mounting columns 1 on both sides of the river channel are equipped with traction devices 3 to control the folding, raising, and unfolding of the fish-blocking electric grid provided in this embodiment. The traction parts of the left electric grid frame 21 and the right electric grid frame 22 are each equipped with pulleys 5 and several annular guide cable buckles 9. One end of the traction cable 4 of the left electric grid frame 21 and the right electric grid frame 22 is connected to the traction device 3 on the side near the traction part, and the other end is limited and guided by the annular guide cable buckle 9, passes through the traction part, and is turned by the pulley 5 to connect with each electrode 7 of the corresponding electrode connection part. The pulleys 5 and the annular guide cable buckles 9 can limit the traction cable 4, thereby enhancing the stability of the traction cable 4 during the retrieval and deployment process.

[0050] The above-described structural relationship between the traction cable 4, the traction section, and the electrode connection section enables the traction device 3 at the end near the traction section of the left electric grid frame 21 or the right electric grid frame 22 to wind up the traction cable 4, thereby pulling the free ends of all the electrodes 7 connected to the corresponding electrode connection section and moving them toward the center of the river channel.

[0051] For ease of understanding, taking the left electric grid frame 21 as an example, one end of the traction cable 4 is fixedly connected to the traction device 3 installed on the left mounting column 1. After passing through the traction part of the left electric grid frame 21, it is fixedly connected to each electrode 7 connected to the electrode connection part of the left electric grid frame 21. When the traction device 3 on the left mounting column 1 performs a winding operation on the traction cable 4, the traction cable 4 can pull the free ends of all the electrodes 7 connected to the electrode connection part of the left electric grid frame 21 and move them towards the center of the river channel, so as to achieve the purpose of folding and storing the electrodes 7 on the left electric grid frame 21.

[0052] The length of electrode 7 can be adjusted according to the changes in the depth of the river channel. Correspondingly, the connection position of the traction cable 4 is adjusted according to the changes in the overall length of electrode 7. This embodiment does not limit this. In order to enable the pulling force of the traction device 3 to be efficiently transmitted to electrode 7, the connection position of traction cable 4 and electrode 7 is located at the lower third of electrode 7.

[0053] Furthermore, such as Figure 7 As shown, regarding the connection between the traction cable 4 and the electrode 7, the electrode 7 is provided with a fixing sleeve 71, and a pressure plate clamp is provided on the fixing sleeve 71. The traction cable 4 is fixedly connected to the electrode 7 by the pressure plate clamp of the fixing sleeve 71, so that when the traction device 3 winds up the traction cable 4, the traction cable 4 can pull up the electrode 7. Specifically, in this embodiment, the distance between the connection points of adjacent electrodes 7 and electrode mounting mechanism 2 is the same as the length of the traction cable 4 between adjacent electrodes 7. Therefore, during the folding process of the fish barrier grid, the angle between the electrode 7 and the electrode mounting beam 2 changes, but the electrode 7 always remains in a parallel state and does not interfere with each other.

[0054] Furthermore, an electrode counterweight 8 is connected to the free end of the electrode 7. The electrode counterweight 8 can exert a vertical pulling force on the electrode 7 by its own weight, which is used to resist the impact of water flow on the electrode 7, so that the electrode 7 can remain stable in a vertical state.

[0055] The operating principle of the folding lifting fish barrier provided in this embodiment is described below. The folding lifting fish barrier provided in this embodiment has two states: vertical and retracted. When the folding lifting fish barrier is in the vertical state, as... Figure 1 , Figure 4 As shown, the electrodes 7 connected to the electrode connection parts of the left electric grid frame 21 and the right electric grid frame 22 are in a drooping state due to their own weight or the influence of the electrode counterweight 8. The electrodes 7 extend towards the bottom of the river to form an electric grid to achieve the function of blocking fish.

[0056] In situations where fishway flood discharge or other conditions require the electrodes 7 to be retracted, the folding lifting fish barrier fence needs to be changed from a vertical state to a retracted state. At this time, the traction devices 3 on both sides of the river channel are activated, and the traction cables 4 are wound up accordingly, pulling the electrodes 7 connected to the traction cables 4 towards the center of the river channel until they are folded away from the river's horizontal plane. At this point, the folding lifting fish barrier fence is in the retracted state. Figure 3 As shown. Specifically, during the process of changing the folding lifting fish barrier from a vertical state to a retracted state, the traction device 3 connected to the left-side column 1 winds up the traction cable 4 set on the left-side barrier frame 21 to pull up each electrode 7 connected to the left-side barrier frame 21 until it is lifted off the horizontal plane and folded into place; the traction device 3 connected to the right-side column 1 winds up the traction cable 4 set on the right-side barrier frame 22 to pull up each electrode 7 connected to the right-side barrier frame 22 until it is lifted off the horizontal plane and folded into place.

[0057] Furthermore, to maximize the efficiency of the electric grid for blocking fish, when the folded and lifted electric grid is in a vertical state, the electrodes 7 connected to the left electric grid frame 21 and the right electric grid frame 22 are spaced at equal intervals.

[0058] Furthermore, each of the mounting columns 1 on both sides of the river channel can be equipped with a hanger device. Both hanger devices include cantilever beams extending towards the opposite bank, which are respectively connected to the left electric grid frame 21 and the right electric grid frame 22. Further, the left electric grid frame 21 is connected to the left electric grid group, and the right electric grid frame 22 is used to connect to the right electric grid group. Simultaneously, the left electric grid frame 21 is rotatably connected to the left mounting column 1 and detachably connected to the right mounting column 1, and the right electric grid frame 22 is rotatably connected to the right mounting column 1 and detachably connected to the left mounting column 1. With the above structure, the left electric grid frame 21 and the right electric grid frame 22 can be placed against the riverbank under the action of the hanger devices they are connected to. That is, driven by the hanger devices, the hanger devices on both sides of the river channel pull the left electric grid frame 21 and the right electric grid frame 22 to rotate via the cantilever beams, causing both the left and right electric grid frames 21 and 22 to perform planar rotational movement until they are close to the riverbank. The rotation directions of the left electric grid frame 21 and the right electric grid frame 22 can be the same or opposite.

[0059] The folding lifting fish barrier provided in this embodiment significantly reduces the height of the installation column compared to a vertical lifting barrier, thereby reducing manufacturing costs and construction difficulty. Furthermore, the transformation from unfolded to folded state can be completed in just a few minutes, significantly accelerating the barrier's storage speed.

[0060] The specific embodiments of this application have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application.
