Description

Technical Field

[0001] The invention belongs to the technical field of leech breeding equipment, in particular to a leech breeding pond water inlet and outlet system and a use method thereof. Background Art

[0002] Leeches belong to the phylum Annelida, class Hirudinidae, and family Hirudinidae. They have high medicinal value. In traditional medicine, leeches are used to treat a variety of diseases, such as thrombosis and hypertension. With the increase in market demand, the leech breeding industry has developed rapidly.

[0003] In the process of leech breeding, given that leeches are highly sensitive to water quality conditions during their life cycle, in order to enhance the controllability of the environment and build a suitable living environment, specially designed breeding ponds are usually used to breed leeches. During the breeding period, an automated water inlet and outlet system is used to monitor and adjust the conditions of the breeding pond, thereby achieving precise control of key parameters such as water temperature, dissolved oxygen, and pH value. This automated system not only improves the breeding efficiency, but also reduces the tediousness of manual operation and reduces labor intensity. In addition, through the automated water inlet and outlet system, continuous monitoring and timely adjustment of water quality in the breeding pond can be achieved to ensure that leeches reproduce in the best growth environment, thereby improving the breeding success rate and yield. However, in the process of implementing automated control of the water body in the breeding pond, leeches are often able to drill into the drainage system because they have significant deformation ability. When the drainage system is started, this not only easily causes blockage of the drainage system, but also may cause casualties and reduced yield of leeches.

[0004] The related art discloses a drainage system for a leech breeding pond and a method of using the same, with application number CN2022107886107. The scheme sets a screen on the drain pipe and uses the screen to intercept leeches, thereby preventing the leeches from escaping through the drainage channel. However, in actual application, it is found that, on the one hand, when the mesh size is too large, the interception rate of the screen for leeches with deformation ability is reduced, and when the mesh size is smaller, the screen has an enhanced interception effect on excrement, impurities, etc. in the water body, which can easily lead to clogging of the screen. On the other hand, when the mesh size is too dense, impurities and leech excrement cannot be discharged with the water body, which has a certain negative impact on the purification and regulation of the water body in the breeding pond.

DETAILED DESCRIPTION

[0050] 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.

[0051] like Figures 1 to 9 As shown, the water inlet and outlet system of a leech breeding pond of the present invention comprises a breeding pond body 1, a water inlet pipe 11 and a water outlet pipe 12;

[0052] The water inlet pipe 11 and the drain pipe 12 are both installed in the culture pond body 1, the water inlet pipe 11 is located above the water surface of the culture pond body 1, and the water inlet pipe 11 is externally connected to a water inlet detection device, the drain pipe 12 is located at the bottom of the culture pond body 1, and the drain pipe 12 is externally connected to a water source purification device;

[0053] It also includes a diversion mechanism, which is installed at the opening of the drain pipe 12 and is used to divert solid debris, leeches and pool water;

[0054] The diversion mechanism includes a diversion screen 2, a mounting roller 24, a connecting frame 25 and a buffer bucket 26;

[0055] A drainage groove 21 is provided in the culture pond body 1, and the drainage pipe 12 is installed at the bottom of the drainage groove 21. A diverter screen 2 is rotatably installed in the culture pond body 1. The diverter screen 2 is a circular sieve plate. The diverter screen 2 extends into the drainage groove 21, and the diverter screen 2 blocks the opening of the drainage pipe 12.

[0056] A water bucket 23 is fixedly installed inside the diverter screen 2, and the opening direction of the water bucket 23 faces the movement direction of the diverter screen 2;

[0057] The culture pond body 1 is provided with a mounting roller 24, and the diverter screen 2 is fixedly provided with a connecting frame 25, and the diverter screen 2 is rotatably mounted on the mounting roller 24 via the connecting frame 25;

[0058] A buffer bucket 26 is detachably fixedly installed in the culture pond body 1. The buffer bucket 26 is located above the water inlet pipe 11. The diverter screen 2 extends above the buffer bucket 26. The bottom of the buffer bucket 26 is made of gauze. The buffer bucket 26 is used to store solid debris and leeches.

[0059] In the leech breeding process, dynamically adjusting the breeding water is one of the means to enhance the stability of the water body and create a suitable leech production environment. When the water body is dynamically adjusted, the water flows through the water inlet and outlet system and circulates in the breeding pond 1 and the external water purification and regulation equipment. In this process, a diversion mechanism is set to separate large particles of solid impurities, leeches and water in the breeding pond 1, which reduces the probability of the drain pipe 12 being blocked on the one hand, and prevents the leeches from escaping through the drain pipe 12 on the other hand.

[0060] Specifically, the drainage trough 21 in the present invention is installed at the bottom of the breeding pond body 1, and is used to cooperate with the water inlet pipe 11 for water circulation. During the drainage process, the water flow carries debris, leech excrement, sludge, etc. to flow into the drainage trough 21, and is screened by the diverter screen 2 before entering the drainage pipe 12. During the screening, small particle impurities pass through the mesh of the diverter screen 2 and enter the water purification equipment together with the water. It should be noted that the water purification equipment recorded in the present invention can be a combination of a water source purification equipment and a water inlet detection equipment, or it can be other water treatment equipment known to those skilled in the art. It should be determined according to the needs of the water treatment process actually adopted. Its main purpose is to treat the breeding water and maintain the stability of the water quality inside the breeding pond body 1. The large particle impurities after diversion and the leeches that accidentally enter the drainage trough 21 are intercepted by the diverter screen 2. As time goes by, the diverter screen 2 corresponding to the drainage trough 21 is gradually blocked. At this time, the staff manually pushes the diverter screen 2 to rotate. Since the diverter screen 2 is annular and is rotatably mounted on the mounting roller 2 through the connecting frame 25 4, so when the diverter screen 2 rotates, the diverter screen 2 and the drain trough 21 generate relative motion, and as the diverter screen 2 continues to rotate, the leeches and debris attached to the diverter screen 2 gradually fall into the water bucket 23 under the action of gravity, and then follow the diverter screen 2 to move above the aquaculture water body under the support of the water bucket 23. When the water bucket 23 rotates to the top with the diverter screen 2, the opening position of the water bucket 23 changes. Under the action of gravity, the water, impurities, and leeches in the water bucket 23 fall downward and are intercepted by the buffer bucket 26. The buffer bucket 26 is a container with an opening at the top, and the bottom of the buffer bucket 26 is made of gauze, so the water entering the buffer bucket 26 will leak through the mesh holes of the gauze, and solid impurities and leeches are collected in the buffer bucket 26. The staff regularly cleans the buffer bucket 26, and when cleaning, the leeches are selected and put back into the breeding pond. The water entering the water purification equipment through the drain pipe 12, after purification and adjustment, flows back to the breeding pond body 1 through the water inlet pipe 11 again, thereby realizing dynamic adjustment of the water body in the breeding pond.

[0061] The present invention provides a diversion mechanism and utilizes the diversion screen 2 to divert the water to be discharged and circulated, so that a small portion of water and most of the solid impurities and leeches are carried by the water bucket 23 and poured into the buffer bucket 26, while most of the water and a small portion of the impurities enter the water purification equipment through the drain pipe 12. Therefore, in the dynamic regulation process of the water body, on the one hand, the probability of leeches escaping is reduced by filtering the discharged water, and on the other hand, the filtered impurities and leeches are transferred and gathered, thereby effectively reducing the probability of the drainage channel being blocked.

[0062] As a preferred embodiment of the present invention, it also includes a reflux mechanism, which is installed on the buffer bucket 26 and is used to drive the leeches in the buffer bucket 26 to flow back into the breeding pond body 1;

[0063] The reflux mechanism comprises a reflux groove 3, a guide plate 31 and a blocking cover;

[0064] The bottom of the buffer bucket 26 is provided with evenly distributed reflux grooves 3;

[0065] A guide plate 31 is installed in the buffer bucket 26. The guide plates 31 are all V-shaped structures. The guide plates 31 extend into the reflux groove 3, and the end of the guide plate 31 with a larger opening is located in the reflux groove 3. The guide plate 31 blocks the reflux groove 3.

[0066] The guide plate 31 is provided with evenly distributed conducting grooves 32 at one end away from the reflux groove 3;

[0067] A blocking cover is installed in the buffer bucket 26 , and the blocking cover corresponds to the guide plate 31 one by one. The blocking cover is used to cover the conducting groove 32 .

[0068] In order to further enhance the convenience of separation of impurities and leeches, a reflux mechanism is provided in the present invention. When leeches and impurities are lifted to above the buffer bucket 26 by the water bucket 23, as the opening position of the water bucket 23 changes, the leeches and impurities fall into the buffer bucket 26. Under the cover of the baffle, the leeches and impurities will not fall directly into the conducting groove 32, but will fall into the bottom of the buffer bucket 26. As time goes by, the leeches move in the buffer bucket 26, and some leeches gradually climb onto the drainage plate 31 and detach from the buffer bucket 26 through the conducting groove 32 on the drainage plate 31. As time goes by, the number of leeches detached gradually increases. Therefore, when the staff cleans the buffer bucket 26, the number of leeches in the buffer bucket 26 is effectively reduced, thereby reducing the labor of the picking work. At the same time, the leeches pass through the conducting groove 32 in time and return to the breeding pond body 1, which can also reduce the probability of leeches being damaged or killed due to environmental changes.

[0069] As a preferred embodiment of the present invention, the blocking cover is composed of a mounting plate 4, a blocking plate 41 and a supporting spring 42;

[0070] The mounting plate 4 is a plate-shaped structure, and a plurality of the mounting plates 4 are connected to form a whole, and a lifting handle 43 is commonly installed on the plurality of mounting plates 4;

[0071] Baffles 41 are hingedly mounted on both sides of the mounting plate 4 , and a support spring 42 is fixedly mounted between the baffles 41 and the mounting plate 4 . In an initial state, two adjacent baffles 41 are close to each other.

[0072] A heat absorbing coating 44 is disposed on the upper surface of the baffle 41 away from the mounting plate 4 .

[0073] In order to further reduce the impact of the diversion treatment on the health of leeches, the present invention adopts the mounting plate 4, the baffle plate 41 and the supporting spring 42 to form a baffle cover. When leeches and impurities fall into the buffer bucket 26, the leeches and impurities fall directly on the baffle plate 41, forcing the baffle plate 41 to compress the supporting spring 42, thereby generating a buffering force for the falling of the leeches. When the baffle plate 41 is deflected, under the action of gravity, the leeches and impurities slide to the bottom of the buffer bucket 26. When the impurities and leeches are mixed, since the end of the upper surface of the baffle plate 41 away from the mounting plate 4 is provided with a heat-absorbing coating 44, the temperature of the end of the inclined baffle plate 41 close to the bottom of the buffer bucket 26 is higher. Under the influence of temperature, the probability of leeches moving at the bottom of the buffer bucket 26 is increased. After losing the pressure of the heavy object, the baffle plate 41 is at Under the action of the support spring 42, the top of the buffer bucket 26 is blocked again. On the one hand, the baffle 41 blocks the top opening of the buffer bucket 26, which can effectively prevent the leeches from being directly exposed to sunlight and reduce the damage to the leeches caused by the lighting environment. On the other hand, the top of the buffer bucket 26 is blocked, which can also prevent the probability of leeches escaping from the top of the buffer bucket 26. The leeches that crawl out through the conducting groove 32 are located at the bottom of the buffer bucket 26. Even if the leeches can move along the outer wall of the buffer bucket 26, because the buffer bucket 26 in the present invention is supported by the bracket, there is a certain distance between it and the edge of the breeding pond body 1, which can greatly reduce the probability of leeches escaping outside the breeding pond body 1. The setting of the lifting handle 43 is to facilitate the staff to remove the cover when cleaning the buffer bucket 26.

[0074] As a preferred embodiment of the present invention, a partition plate 5 is fixedly installed in the breeding pond body 1, and a drainage channel 51 is formed between the partition plate 5 and the breeding pond body 1. An inclined extension bucket 52 is installed at the bottom of the buffer bucket 26, and the opening of the extension bucket 52 is located above the drainage channel 51. The drainage channel 51 is used to guide the leeches to avoid the drainage trough 21 when returning.

[0075] Since the buffer bucket 26 is located above the drainage trough 21, in order to reduce the probability of leeches falling from the buffer bucket 26 and entering the drainage trough 21 again, the present invention is provided with an extension bucket 52 and a partition plate 5, wherein the partition plate 5 is fixedly installed in the culture pond body 1, and a drainage channel 51 is formed between the partition plate 5 and the inner wall of the culture pond body 1, and the opening of the extension bucket 52 is located just above the drainage channel 51. When the leeches fall from the through groove, they are intercepted by the extension bucket 52 and crawl out from the opening of the extension bucket 52. During this process, since the diverter screen 2 is in continuous operation, the water bucket 23 periodically pours a mixture of water and impurities into the buffer bucket 26. After the water is filtered by the buffer bucket 26, it enters the extension bucket 52 and flows out from the opening of the extension bucket 52. Therefore, under the impact of the periodic water flow, the leeches fall from the opening of the extension bucket 52. After the leeches fall into the drainage channel 51, they are guided through the drainage channel 51, thereby reducing the probability of the leeches entering the drainage trough 21 again.

[0076] As a preferred embodiment of the present invention, a water-absorbing cotton strip 53 is fixedly installed in the buffer bucket 26, and the water-absorbing cotton strip 53 extends and is fixed into the extension bucket 52. The water inlet pipe 11 extends into the extension bucket 52, and the water inlet pipe 11 is designed with an opening corresponding to the gap between the water-absorbing cotton strip 53.

[0077] In order to further enhance the impact effect on the leeches in the extension bucket 52, the water inlet pipe 11 in the present invention extends into the extension bucket 52, and the water inlet pipe 11 is opened in the inner cavity of the buffer bucket 26. The water inlet pipe 11 continuously supplies water to the buffer bucket 26, so that there is always water flow impact in the extension bucket 52. At the same time, since the absorbent cotton strips 53 fixedly installed in the buffer bucket 26 synchronously extend into the extension bucket 52, when the water flows, the capillary action of the absorbent cotton strips 53 maintains a moist environment in the buffer bucket 26, thereby reducing the probability of damage to the leeches in the buffer bucket 26.

[0078] As a preferred embodiment of the present invention, the arrangement direction of the drain pipe 12 in the drain groove 21 is the same as the tangent direction of the diverter screen 2 , and the water flow direction in the drain groove 21 is consistent with the rotation direction of the diverter screen 2 .

[0079] A driving member 6 is installed on the culture pond body 1 , and the driving member 6 is transmission-connected to the connecting frame 25 .

[0080] In order to further enhance the convenience of system operation, the opening direction of the drain pipe 12 in the present invention is consistent with the tangent direction of the diverter screen 2, and the water flow direction in the drain trough 21 is consistent with the rotation direction of the diverter screen 2. Therefore, in the process of continuous drainage, the water flow movement will give the diverter screen 2 a driving force, prompting the diverter screen 2 to have a tendency to rotate. At the same time, a driving member 6 is provided, and the driving member 6 is connected to the connecting frame 25 for transmission. In this embodiment, the driving member 6 is preferably a driving motor, and the driving member 6 and the connecting frame 25 are connected by belt transmission. Therefore, under the joint action of the driving member 6 and the impact of the water flow, the diverter screen 2 is able to rotate stably, and then in the process of water dynamic adjustment, impurities and water flow are continuously diverted, thereby effectively reducing the probability of the drainage channel being blocked.

[0081] like Fig.10 As shown, a method for using a water inlet and outlet system for a leech breeding pond comprises the following steps:

[0082] S1, water inlet: adjust the temperature, pH value and dissolved oxygen content of the pre-purified aquaculture water to the values ​​specified in the leech aquaculture process, and then pass it into the water inlet pipe 11;

[0083] S2, circulation: open the end of the drainage pipe 12 outside the culture pond 1, and with the help of the pumping equipment, discharge the aquaculture water in the culture pond 1, and after being discharged, it is purified, PH adjusted, and oxygen content adjusted, and then transported to the water supply pipe again;

[0084] S3, diversion: When the aquaculture water flows to the drain pipe 12, it is filtered through the diversion screen 2. At the same time, the diversion screen 2 is driven by the driving member 6 to rotate. During the rotation, the debris and leeches attached to the diversion screen 2 are lifted and finally dumped into the buffer bucket 26;

[0085] S4, cleaning: During the long-term water circulation process, the debris generated in the aquaculture pond is gathered in the buffer bucket 26. After the staff manually screens the buffer bucket 26, the debris can be cleaned to maintain the continuous circulation of aquaculture water.
