Description

Technical Field

[0001] The utility model relates to the field of ecological water conservancy projects, in particular to an automatic temperature control and light adjustment system for fishways to improve the fish passing effect. Background Technique

[0002] In the construction of water conservancy and hydropower engineering facilities, the situation of rivers being cut off often occurs, which has an impact on the natural migration and reproduction of fish. To solve this problem, various ecological water conservancy projects, such as fishways, have been designed to help fish swim back smoothly. However, the existing fishways often have poor fish passing effects or even completely fail due to improper control of light and water temperature.

[0003] In the case of the construction of water conservancy and hydropower engineering facilities, many projects cut off rivers. To ensure that fish can return and reproduce, a type of ecological water conservancy project has been designed. So far, some of the built fishways often have poor fish passing effects or even completely fail due to poor control of factors such as light and water temperature.

[0004] Therefore, the design of fishways considering the ecological characteristics of fish is particularly important. In order for fish to reproduce normally and maintain ecological balance, the innovative design of fishways is extremely urgent. Compared with traditional fishways, this design takes into account the impact of light on fish and adds a shading sliding awning. It can automatically shade and supplement light by sensing the light intensity through computer sensing technology. At the same time, considering the stability of the computer-controlled telescopic awning, this design uses a fence-type support frame and adopts a slideway design at the bottom to make the awning telescopic more convenient. To ensure the stability of the fence and good shading, a complete awning is used as a whole. At the same time, the awning will be at the same height as the bottom of the fence support frame. Some supplementary lights can be installed on the support frame inside the awning for supplementary lighting. Double-layer materials are used in terms of materials. Black materials are used inside to ensure light shading, and bright colors mainly white are used outside to avoid heat absorption and cause too high a temperature inside the light-shading fishway. At the same time, interferon is placed inside the fishway to prevent insect interference.

[0005] The invention with the application number CN202110510421.9 discloses a fishway, including an inlet section, a passing section and an outlet section. A fish collecting lamp is arranged at the inlet section, and a fish fin-shaped sound vibration device is arranged at the inlet section. The fishway of the present invention, based on the auditory and visual motor response characteristics of fish, uses mechanical devices to simulate, significantly improves the fish attracting effect and fish passing efficiency of the fishway, and reduces the ecological impact caused by artificial dam construction.

[0006] However, the fishway in the above patent technology still cannot solve the problem of automatic adjustment of water temperature and light intensity in the fishway, nor does it provide effective technical inspiration for the problems existing in the prior art. Content of the Utility Model

[0007] The purpose of the present utility model is to provide an automatic water temperature and light regulation system for fishways to solve the problems raised in the above background technology:

[0008] (1) How to automatically adjust according to the water temperature and light intensity in the fishway, create a suitable fish passage environment, and improve the passing rate of fish.

[0009] To achieve the above object, the present utility model provides the following technical solutions:

[0010] An automatic water temperature and light regulation system for fishways;

[0011] It includes a fishway main body and at least one set of adjustment mechanisms;

[0012] The fishway main body is provided with a fishway channel for fish groups to pass through. All the adjustment mechanisms are sequentially arranged on the upper side of the fishway main body. The adjustment mechanism includes an adjustment seat, at least one high-temperature resistant light-shielding film, and at least one set of telescopic components. The adjustment seat is fixedly connected to the upper side of the fishway main body. The adjustment seat is provided with a light regulation slot opening penetrating its upper and lower end faces corresponding to the position of the fishway channel of the fishway main body. The adjustment seat is also provided with at least one set of sliding slot openings. Each set of sliding slot openings includes two horizontally arranged sliding slot openings. The two sliding slot openings in the same group are respectively located on both sides of the light regulation slot opening and are respectively communicated with the light regulation slot opening. The adjustment seat is fixedly connected with at least one film recycling bin. At least one film recycling bin, at least one set of sliding slot openings, at least one high-temperature resistant light-shielding film, and at least one set of telescopic components are in one-to-one correspondence. The film recycling bin is respectively communicated with the light regulation slot opening and the corresponding group of sliding slot openings. The telescopic component includes two electric push rods. The two electric push rods are respectively installed in the film recycling bin. The piston rods of the two electric push rods can respectively extend into the sliding slot openings. Both sides of the high-temperature resistant light-shielding film are respectively fixedly connected to the piston rods of the two electric push rods. The high-temperature resistant light-shielding film can move from the film recycling bin to the light regulation slot opening under the action of the two electric push rods.

[0013] Compared with the existing fishway, where the long-term direct sunlight on the water surface in nature causes the temperature to be too high, resulting in a reduction in the number of fish passing through the fishway, the design of the present utility model avoids a significant increase in the water temperature in the fishway due to direct sunlight, and can also block avian predators from squatting at fixed points in the fishway to avoid scaring the fish. And when the water temperature is low, the heating plates on both sides start to work to ensure that the water temperature is at a suitable temperature. The interferon design on the inner side can avoid insect interference, which has the advantage of being conducive to attracting fish to pass through the fishway and can effectively improve the passing rate of fish.

[0014] On the basis of the above technical solutions, the present utility model can be further improved as follows.

[0015] Furthermore, the adjustment mechanism includes a plurality of high-temperature resistant light-shielding films and a plurality of telescopic components. The adjustment seat is also provided with a plurality of groups of sliding slot openings. The plurality of groups of sliding slot openings are arranged vertically in sequence. The adjustment seat is fixedly connected with a plurality of film recycling bins;

[0016] The film recovery bins, the sliding slots, the high-temperature resistant light-shielding films, and the telescopic components are in a one-to-one correspondence. Multiple layers of high-temperature resistant light-shielding films are used to control the light intensity in the fishway.

[0017] Furthermore, all high-temperature resistant light-shielding films have different light-shielding rates.

[0018] Furthermore, among all the high-temperature resistant light-shielding films, the light-shielding rates of two adjacent high-temperature resistant light-shielding films in the vertical direction differ by 10%.

[0019] Furthermore, heating plates are installed on both sides of the side walls of the fishway main body, which are used to heat the water in the fishway when the water temperature is too low to maintain a suitable water temperature.

[0020] Furthermore, a water temperature monitoring board is installed on the bottom wall of the fishway channel of the fishway body. The water temperature monitoring board is used to monitor the water temperature in the fishway in real time.

[0021] Furthermore, a blocking plate is provided at the opening of the sliding slot on the side away from the film recovery bin.

[0022] Different fish species may have different needs and preferences for light. Light has a significant impact on fish behavior, physiology, navigation, and migration. When designing fishways, the following factors need to be considered: When considering the range of light, the ecological needs of fish, such as the dependence of behaviors such as reproduction and foraging on light, must also be considered. In some cases, artificial lighting may be needed to simulate natural light conditions, especially in seasons or areas with insufficient light. In order to prevent predation by natural enemies such as birds, fishways may require specific light-blocking designs to protect fish.

[0023] This fishway automatic water temperature and light control system can adjust the water temperature in the fishway by avoiding direct sunlight to ensure that the water temperature in the fishway is most suitable for fish. It can effectively avoid bird natural enemies and avoid direct sunlight in summer that causes the water temperature to be too high, reducing the fish passage rate, thereby attracting fish to pass through.

[0032] Embodiment 1

[0033] Please refer to Figures 1 to 3 。

[0034] This fishway automatic water - temperature and light - adjusting system includes a fishway main body 100 and two groups of adjusting mechanisms;

[0035] The fishway main body 100 is provided with a fishway channel 110 for fish to pass through. All the adjusting mechanisms are sequentially arranged on the upper side of the fishway main body 100. The adjusting mechanism includes an adjusting seat 210, three high-temperature resistant light-shielding films 230, and three groups of telescopic components. The adjusting seat 210 is fixedly installed on the upper side of the fishway main body 100. The adjusting seat 210 is provided with a light-adjusting notch 211 penetrating its upper and lower end faces corresponding to the position of the fishway channel 110 of the fishway main body 100. The adjusting seat 210 is also provided with three groups of sliding notches 212. The three groups of sliding notches 212 are arranged vertically in sequence. Each group of sliding notches 212 includes two horizontally arranged sliding notches 212. The two sliding notches 212 in the same group are respectively located on both sides of the light-adjusting notch 211 and are respectively communicated with the light-adjusting notch 211. The adjusting seat 210 is fixed with three film recovery bins 213. The three film recovery bins 213, the three groups of sliding notches 212, the three high-temperature resistant light-shielding films 230, and the three groups of telescopic components are in one-to-one correspondence. The film recovery bins 213 are respectively communicated with the light-adjusting notch 211 and the corresponding group of sliding notches 212. A blocking plate 214 for preventing the high-temperature resistant light-shielding film 230 from slipping is arranged at the opening of the sliding notch 212 on the side far from the film recovery bin 213;

[0036] The telescopic component includes two electric push rods 220. The two electric push rods 220 are respectively installed in the film recovery bin 213. The piston rods of the two electric push rods 220 can respectively extend into the sliding notch 212.

[0037] The high-temperature resistant light-shielding film 230 is made of a black TPU film (a commercially available product) with a thickness of about 0.25 mm. Both sides of the high-temperature resistant light-shielding film 230 are respectively fixed on the piston rods of the two electric push rods 220. The high-temperature resistant light-shielding film 230 can move from the film recovery bin 213 to the light-adjusting notch 211 under the action of the two electric push rods 220. At the same time, a rectangular collecting device is designed at the starting position to facilitate the collection and update of the film while controlling the light-shielding rate. Moreover, the gaps designed between the upper, middle, and lower layers of the high-temperature resistant light-shielding films 230 can prevent the film from being adhered by water vapor and damaged. The distance between the lowermost high-temperature resistant light-shielding film 230 and the liquid level is 75 cm to 80 cm.

[0038] Heating plates 111 are installed on both sides of the side wall of the fishway channel 110 of the fishway main body 100. A wire hole groove for the heating plate 111 is designed below the adjusting seat 210. When the water temperature is too low, the computer analyzes and controls the heating plate 111 to heat. The water temperature in the fishway is at the most suitable temperature for fish. The heating plates 111 are fixed on the two walls of the fishway to ensure that the water temperature can be controlled at an appropriate temperature to ensure the passage of fish even when the water temperature is too low.

[0039] Moreover, a water temperature monitoring board 112 is installed on the bottom wall of the fishway channel 110 of the fishway main body 100. The water temperature monitoring board 112 transmits the sensed data to a computer through internal lines. The computer integrates and analyzes the data, and then controls the forward and backward movement of the telescopic component and the film to play an overall regulation role. At the same time, it also controls the heating plate 111 to work.

[0040] During use, when the temperature-sensitive control panel senses that the water temperature in the fishway changes to an unsuitable level for fish, the computer analyzes whether the water temperature is too high or too low, and then controls the thruster to control the forward or backward movement of the light-shielding film. The pushed film controls the expansion and contraction of the film as needed to ensure that the water temperature is most suitable for fish.

[0041] At the same time, a recycling space is set at the end of the device. The inner side of the recycling device uses double rollers to remove excess water on the film. When the water temperature is low, the computer will charge and turn on the heating plate 111 as needed to raise the water temperature. At the same time, interferon is placed inside the fishway to prevent insect interference.

[0042] In addition, for the fishway project, the automatic water temperature and light regulation system of this fishway can also be provided with an automatic induction light-shielding and light-supplementing device. The light-supplementing device can timely adjust the water temperature in the fishway to ensure that the fishway has the most suitable light intensity and temperature. The covering design of the film can effectively avoid the squatting attack of birds. The adjustment of light can effectively prevent the water temperature in the fishway from rising significantly due to direct sunlight. When the light intensity is too weak, the bulbs on both sides will be turned on in a timely manner after computer analysis to supplement light. At the same time, interferon is placed inside the fishway to prevent insect interference, which has the advantage of being conducive to attracting fish to pass through the fishway and can effectively improve the fish passing rate.

[0043] The water temperature monitoring board 112 monitors the water temperature in the fishway in real time and transmits the data to the computer control system. The computer control system automatically adjusts the propulsion device according to the water temperature data to control the forward and backward movement of the light-shielding film to adjust the light intensity in the fishway.

[0044] When the water temperature is too high, the computer control system controls the heating plate 111 to stop working; when the water temperature is too low, the computer control system starts the heating plate 111 to heat the water in the fishway and maintain a suitable water temperature. The film recycling device recycles the light-shielding film when needed to ensure the continuous operation of the system.

[0045] Comparative experiment, the following are the experimental results of the comparative experiment:

[0046]

[0047] Example two

[0048] The difference between this embodiment and the first embodiment is only that: in this embodiment, the three-layer high-temperature resistant light-shielding film can be started sequentially according to the light conditions. For example, when the outdoor temperature is 36°, one layer is started when the average total radiation is 127W / m 2 ^~159W / m 2 and three layers are started when the average total radiation is 160W / m 2 ^~298W / m 2 and three layers are started when the average total radiation is 299W / m 2 ^~368W / m 2 and three layers are started when the average total radiation is 368W / m

[0049] This embodiment can start the three-layer high-temperature resistant light-shielding film according to different light intensities (including the net short-wave radiation on the ground and the downward long-wave radiation of the atmosphere).

[0050] It is also possible to change the light-shielding rate of the high-temperature resistant light-shielding film. There are differences in the light transmittance of the upper, middle and lower three-layer high-temperature resistant light-shielding films. The light shielding of the three-layer high-temperature resistant light-shielding film forms an arithmetic function, and the light-shielding rate of each layer differs by 10%.

[0051] The above are only two implementation manners of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several modifications and improvements can be made, and these should also be regarded as belonging to the protection scope of the present utility model.
