Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fishery breeding, in particular to a device for assisting fish mating. Background Art
[0002] Crucian carp, carp and bighead carp are common freshwater fish that undergo in vitro fertilization. Usually, the female fish releases eggs and the male fish releases sperm. The two meet in the water and combine to form a fertilized egg. In vitro fertilization can increase the success rate of fertilization and is beneficial to the spread of the population and successful reproduction.
[0003] Some freshwater fish fertilized in vitro have the habit of eating eggs after spawning, resulting in a low survival rate of fish eggs. In the process of fish farming, if the fish rely on natural mating and reproduction, the reproduction rate will be reduced due to fish eating eggs. In the prior art, the survival rate of fish eggs is improved by using auxiliary devices to separate fish eggs from fish, but the existing auxiliary devices are inconvenient for collecting fish eggs, and the collection process is cumbersome. Utility Model Content
[0004] The purpose of the utility model is to provide a device for assisting fish mating which is convenient for collecting fish eggs and effectively solves the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.
[0006] A device for assisting fish mating comprises an outer cylinder body, an inner filter cartridge is arranged in the outer cylinder body, a temporary storage cavity is formed between the outer wall of the inner filter cartridge and the inner wall of the outer cylinder body, the outer cylinder body is divided into a vertical portion and a funnel portion, the funnel portion is located below the vertical portion, the inner diameter of the funnel portion decreases downwards, a discharge pipe is fixed to the bottom end of the funnel portion, a collecting tank is installed at the bottom end of the discharge pipe, a vertical discharge channel is arranged in the discharge pipe, the top of the discharge channel is communicated with the bottom of the funnel portion, the bottom of the discharge channel is communicated with the collecting tank, a plurality of filter holes are evenly distributed on the bottom of the collecting tank, and an opening and closing mechanism is arranged on the discharge pipe.
[0007] It can be seen that when the fish is placed in the inner filter, the female fish lays eggs and the male fish lays sperm, fertilized eggs are formed. Under the action of gravity, the fertilized eggs pass through the filter holes on the inner filter and fall into the temporary storage cavity. The fish and eggs are separated by the isolation effect of the inner filter, so as to avoid the situation where the fish eats the eggs and improve the survival rate of the fish eggs. By operating the opening and closing mechanism, the blockage of the discharge channel is cancelled, and the water in the outer cylinder flows into the discharge channel through the bottom of the funnel and flows into the collection tank. Finally, the water is discharged through the filter holes at the bottom of the collection tank, while the fish eggs remain in the collection tank, so as to achieve the fish egg collection effect and ensure that the fish egg collection is convenient enough. The bottom of the outer cylinder is set to a funnel shape with a large top and a small bottom, which helps to discharge all the fish eggs and reduces the probability of the fish eggs being retained on the inner wall of the outer cylinder, thereby improving the collection rate of the fish eggs.
[0008] Furthermore, the opening and closing mechanism includes a blocking plate and a pinch handle. A horizontally extending slide groove is provided on the discharge pipe, and the slide groove runs through the discharge channel. The blocking plate is slidably inserted in the slide groove to block the discharge channel. One end of the blocking plate extends to the outer side of the discharge pipe and is equipped with a pinch handle.
[0009] By pinching the handle and pulling the sealing plate outward to slide, the sealing plate can cancel the blockage of the discharge channel, making it easy to discharge the water and fish eggs in the outer cylinder into the collection tank for filtration. By pinching the handle and pushing the sealing plate inward to the bottom, the sealing plate can block the discharge channel to avoid water leakage during fish mating.
[0010] Furthermore, slots are symmetrically arranged on both sides of the inner wall of the inner filter cartridge, and a partition is vertically slidably inserted between the two slots, and the partition divides the inner filter cartridge into two parts.
[0011] By vertically inserting the partition into the two slots, the inner filter cartridge is divided into two parts, so that male fish and female fish can be placed separately. During mating, the partition is vertically pulled out to remove the barrier between male fish and female fish, making mating convenient.
[0012] Furthermore, the collecting tank is screwed onto the lower end of the discharge pipe through thread matching, so that it has a detachable effect.
[0013] By setting the collecting tank to be threaded and detachable, after the fish eggs are collected, the collecting tank can be removed from the lower end of the discharge pipe by twisting the collecting tank, so that the fish eggs collected in the collecting tank can be transferred easily.
[0014] Furthermore, handles are installed on both sides of the collection tank, and the outsides of the handles are provided with anti-slip grooves.
[0015] By holding the handle, it is convenient to exert force to twist and disassemble the collection tank. The anti-slip texture arranged on the outside of the handle can increase the friction between the handle surface and the hand to avoid slipping.
[0016] Furthermore, the device for assisting fish mating also includes a base, four columns are vertically fixed on the upper surface of the base, the outer cylinder is fixed on the top of the four columns, and four universal wheels are installed on the lower surface of the base.
[0017] The universal wheels make it easy to transfer the entire device, thereby increasing the flexibility of the device.
[0018] Furthermore, a water collecting trough is provided on the upper surface of the base, and the water collecting trough is located corresponding to the bottom end of the collection tank.
[0019] The water filtered out from the bottom of the collection tank eventually flows into the sump to collect wastewater.
[0020] Furthermore, a water inlet pipe communicating with the interior is connected to the side of the outer cylinder near its top end, and a drainage pipe communicating with the interior is connected to the side of the water collecting tank near its bottom end.
[0021] Compared with the prior art, the beneficial effects of the present invention are as follows.
[0022] 1. The utility model places fish in the inner filter cartridge. After the female fish lays eggs and the male fish lays sperm, fertilized eggs are formed. Under the action of gravity, the fertilized eggs pass through the filter holes on the inner filter cartridge and fall into the temporary storage cavity. The isolation effect of the inner filter cartridge is utilized to separate the fish and the eggs, thereby preventing the fish from eating the eggs and improving the survival rate of the fish eggs.
[0023] 2. The utility model cancels the blockage of the discharge channel by operating the opening and closing mechanism. The water in the outer cylinder flows into the discharge channel through the bottom of the funnel and flows into the collection tank. Finally, the water is discharged through the filter holes at the bottom of the collection tank, while the fish eggs remain in the collection tank, thereby achieving the fish egg collection effect and ensuring that the fish egg collection is sufficiently convenient.
[0024] 3. The utility model sets the bottom of the outer cylinder into a funnel shape that is larger at the top and smaller at the bottom, which helps to discharge all the fish eggs and reduces the probability of the fish eggs being retained on the inner wall of the outer cylinder, thereby improving the collection rate of the fish eggs.
