Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a water level monitoring device for eel fry culture. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture has extensive farming, intensive farming and high-density intensive farming. Extensive farming is to release seedlings in medium and small natural waters and grow aquatic products completely relying on natural bait, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming is to grow aquatic products in smaller water bodies by feeding and fertilizing, such as fish farming in fish ponds, cage fish farming and fence farming. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation and feeding high-quality bait to carry out high-density farming in small water bodies to obtain high yields, such as high-density running water farming of fish and shrimp. Generally speaking, the water level of the fish pond can be deepened to more than 2 meters, and the water level of the fish breeding pond can be deepened to 1.5-2 meters. For fish ponds with convenient water sources, new water is added every 10 days or so; for fish ponds with inconvenient water sources, new water is added every 15-20 days, and the amount of water added and changed each time is about one-third or one-quarter of the pool water capacity. Be careful not to let industrial wastewater and pesticide-contaminated water flow into the fish pond to prevent diseases. In view of the low water level of fish ponds and the poor water source of the external river, the method of gradually adding pond water in small amounts every three or five days is adopted to gradually raise the water level of the fish pond to more than 1.2 meters. Each time water is added, it is selected from 10 am to 2 pm on a sunny day. The depth of the fish pond is very important for aquaculture. At present, the water level of the fish pond is mostly determined by observation, which requires certain experience, and the direct determination by observation often has a certain error from the actual situation.

[0025] In the embodiment, Figure 1-5 Provided is a water level monitoring device for eel fry breeding, comprising a base 1, a connection knot 2 is fixedly connected to the top of the base 1, a support rod 3 is fixedly connected to the inner side of the connection knot 2, a connection arm 4 is fixedly connected to the outer side of the support rod 3, a fixing assembly 5 is arranged on the connection arm 4, a rangefinder 6 is fixedly connected to the fixing assembly 5, a first connecting pipe 7 is fixedly connected to the inner side of the base 1, a filter screen 8 is arranged on the left end of the first connecting pipe 7, the filter screen 8 is clamped on the outer side of the first connecting pipe 7 through a clamping assembly 9, a two-way pump 10 is connected to the right end of the first connecting pipe 7, a second connecting pipe 11 is connected to the right end of the two-way pump 10, and an auxiliary support assembly 12 is arranged on the outer side of the support rod 3;

[0026] The fixing assembly 5 includes a slide groove 51, a pin hole 52, a slide rod 53, a pin groove 54 and a latch 55. The slide groove 51 is provided on the inner side of the connecting arm 4, and the pin hole 52 connected to the slide groove 51 is provided on the top of the connecting arm 4. The slide rod 53 is slidably connected to the inner side of the slide groove 51, and a plurality of pin grooves 54 are provided on the slide rod 53. A latch 55 with one end extending to the inner side of the pin groove 54 is provided on the inner side of the pin hole 52.

[0027] Through the above arrangement, the slide bar 53 is inserted along the slide groove 51. When the pin groove 54 is aligned with the pin hole 52, the plug 55 is inserted from the pin hole 52 until the plug 55 contacts the bottom wall of the inner cavity of the pin groove 54 to complete the fixation of the rangefinder 6. When the rangefinder 6 measures that the water surface height is higher than the highest defined water level, the two-way pump 10 pumps water out of the first connecting pipe 7 and discharges it through the second connecting pipe 11. When the water surface height reaches the appropriate defined water level, the two-way pump 10 stops working. When the water surface height measured by the rangefinder 6 is lower than the lowest defined water level, the two-way pump 10 stops working. When the water level reaches a suitable level, the two-way pump 10 stops working. During this process, the filter screen 8 can filter out impurities and prevent the eel fry from escaping. When the filter screen 8 is blocked by impurities, the filter screen 8 can be removed by disassembling the clamping assembly 9, and a new filter screen 8 can be replaced and clamped on the outside of the first connecting pipe 7 by the clamping assembly 9. Since it is difficult to fix the filter screen on the muddy ground in the fish pond, an auxiliary support assembly 12 is required to complete the auxiliary fixation.
