[0003] However, as far as the current leech breeding ponds are concerned, the water level is actually automatically controlled through water level sensors. However, the sensing range of a single specification of water level sensors is fixed. When installed inside breeding ponds of different sizes, water level sensors of different specifications need to be matched for use. The adaptability is poor, and the installation and debugging of the water level sensors require professional personnel to operate, which is not convenient for subsequent self-regulation and use. It is difficult to get started, has poor flexibility, and is not practical. Summary of the invention

[0033] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 12 As shown: Embodiment 1: The present invention provides a leech breeding pond with convenient water level control, comprising a breeding pond 1 and a water level control component, wherein the water level control component is composed of a mounting mechanism 2, a lower limit mechanism 3, an upper limit mechanism 4 and a linkage mechanism 5; The mounting mechanism 2 includes a mounting seat 201, a lower limit screw rod 202 and an upper limit screw rod 203. The mounting seat 201 is fixedly mounted on the inner wall of the culture pond 1, and the lower limit screw rod 202 and the upper limit screw rod 203 are rotatably connected to two sides of the interior of the mounting seat 201 respectively; The lower limit mechanism 3 includes a control seat 301, a lower limit positioning seat 302 and a lower limit floating block 303. The control seat 301 is inserted into the interior of the mounting seat 201, and the lower limit positioning seat 302 is inserted into the bottom of the mounting seat 201. The lower limit screw rod 202 is screwed into the interior of the lower limit positioning seat 302 through a rod body thread, and the lower limit floating block 303 is inserted into the interior of the lower limit positioning seat 302. The upper limit mechanism 4 includes a force application seat 401, an upper limit positioning seat 402 and an upper limit floating block 403. The force application seat 401 is inserted into the interior of the mounting seat 201, and the upper limit positioning seat 402 is inserted into the bottom of the mounting seat 201. The upper limit screw rod 203 is screwed into the interior of the upper limit positioning seat 402 through the rod body thread, and the upper limit floating block 403 is inserted into the interior of the upper limit positioning seat 402. There are two groups of linkage mechanisms 5 , and the two groups of linkage mechanisms 5 are respectively arranged inside the lower limit mechanism 3 and the upper limit mechanism 4 .

[0035] In the disclosed embodiment, the linkage mechanism 5 includes a conversion column 501 and a synchronization rod 502, the synchronization rod 502 is inserted into the interior of the conversion column 501, and the synchronization rod 502 can drive the conversion column 501 to rotate synchronously when rotating, wherein the conversion column 501 of one group of linkage mechanisms 5 is rotationally connected to the interior of the control seat 301, and the synchronization rod 502 is fixedly installed on the top of the lower limit float 303, and the conversion column 501 of another group of linkage mechanisms 5 is rotationally connected to the interior of the force application seat 401, and the synchronization rod 502 is fixedly installed on the top of the upper limit float 403. In use, the lower limit mechanism 3 can control the lower limit position of the water level inside the breeding pond 1, and when the water level inside the breeding pond 1 reaches the lower limit position, the water supply and replenishment operation can be automatically started, and the upper limit mechanism 4 can control the upper limit position of the water level inside the breeding pond 1, and when the water level inside the breeding pond 1 reaches the upper limit position, the water supply and replenishment operation can be stopped, thereby The water level inside the breeding pond 1 is always within a suitable range, and under the setting of the two sets of linkage mechanisms 5, the upper and lower limits of the water level inside the breeding pond 1 can be freely adjusted without interfering with each other. The linkage mechanism 5 can convert the lifting action into a rotation action, and then convert the rotation action into a lifting action. When it is necessary to adjust the lower limit position of the water level inside the breeding pond 1, it is only necessary to rotate the lower limit screw 202. When the lower limit screw 202 rotates, it can drive the lower limit positioning seat 302 to move up and down, thereby changing the use position of the lower limit floating block 303, that is, the lower limit position of the water level inside the breeding pond 1. When it is necessary to adjust the upper limit position of the water level inside the breeding pond 1, it is only necessary to rotate the upper limit screw 203. When the upper limit screw 203 rotates, it can drive the upper limit positioning seat 402 to move up and down, thereby changing the use position of the upper limit floating block 403, that is, the upper limit position of the water level inside the breeding pond 1. The regulation is convenient and flexible to use.

[0036] In the embodiment of the present disclosure, the bottom of the control seat 301 and the interior of the mounting seat 201 are both provided with a conductive disk 2011, and the two conductive disks 2011 are on the same vertical line. When the two conductive disks 2011 are in contact, the power supply of the water pump that supplies water to the inside of the culture pond 1 can be connected. The bottom of the control seat 301 and the interior of the mounting seat 201 are both provided with a retaining magnetic suction block 2012, and the retaining magnetic suction block 2012 is on the same vertical line. When the retaining magnetic suction blocks 2012 of the control seat 301 and the mounting seat 201 are attracted to each other, the two conductive disks 2011 are in contact with each other. In use, taking the water level in the culture pond 1 at the upper limit position as an example, and for the sake of convenience of understanding, the lower limit float 303 is completely immersed The maximum buoyancy generated when the upper limit float 403 is immersed in the water is Fc, and the outer part of the conversion column 501 is provided with a spiral conversion groove 5011, and the inner part of the mounting seat 201 is provided with a conversion protrusion 2013, and the conversion protrusion 2013 is plugged into the inner part of the conversion groove 5011. At this time, the conversion protrusion 2013 is located at the bottom end of the conversion groove 5011, so that the control seat 301 and the force seat 401 are both in a lifted state. At this time, the two conductive disks 2011 are separated from each other, and the two groups of holding magnetic suction blocks 2012 are also in a separated state and will not be attracted, so that the power supply of the water pump will not be connected at this time, and at this time, the upper limit float 403 is immersed in the water. The block of the limit float 403 is half submerged in the water. With the increase of breeding time or the artificial discharge and replacement of the water inside the breeding pond 1, the water level inside the breeding pond 1 will drop. When the water level inside the breeding pond 1 is still within the appropriate range (between the upper limit and the lower limit), the automatic water supply and replenishment operation will not be triggered at this time. The outer part of the upper limit float 403 is provided with a spiral upper limit linkage groove 4031, and the inner part of the upper limit positioning seat 402 is provided with an upper limit linkage protrusion 4021, and the upper limit linkage protrusion 4021 is plugged into the inner part of the upper limit linkage groove 4031. At this time, due to the drop in water level, the upper limit float 403 will also drop with the water level, and the upper limit linkage protrusion of the upper limit float 403 will be raised when the upper limit float 403 drops. 4021 will rotate under the action of the upper limit linkage groove 4031. When the upper limit float block 403 rotates, it can drive the conversion column 501 of the same linkage mechanism 5 to rotate through the synchronization rod 502 on its top. When the conversion column 501 rotates, the conversion groove 5011 can drive the force seat 401 to move downward through the conversion protrusion 2013 to restore the lowest use position. When the lower limit float block 303 is completely immersed in water, the buoyancy generated by the lower limit float block 303 is not enough to separate the mutually attracted retaining magnetic blocks 2012. At this time, since the lower limit float block 303 is still immersed in water, the use position of the lower limit mechanism 3 will not change, and the water supply and replenishment operation inside the breeding pond 1 will not be triggered in advance, and the use is stable.

[0037] In the embodiment of the present disclosure, the outer part of the lower limit floating block 303 is provided with a spiral lower limit linkage groove 3031, and the inner part of the lower limit positioning seat 302 is provided with a lower limit linkage protrusion 3021, and the lower limit linkage protrusion 3021 is inserted into the inner part of the lower limit linkage groove 3031. In use, as the water level continues to drop, when the water level drops to the lower limit position, the lower limit floating block 303 will drop synchronously with the water level, and when the lower limit floating block 303 drops, the lower limit linkage protrusion 3021 will drive the lower limit floating block 303 through the lower limit linkage groove 3031. When the lower limit float 303 descends, it can drive the conversion column 501 of the same linkage mechanism 5 to rotate through the synchronization rod 502 on its top. When the conversion column 501 rotates, the conversion groove 5011 can drive the control seat 301 to move downward through the conversion protrusion 2013. When the control seat 301 moves downward, the two groups of magnetic blocks 2012 are attracted to each other, and the two conductive disks 2011 contact each other to turn on the power of the water pump, so that when the water level reaches the lower limit, water is automatically supplied to the inside of the breeding pond 1. It is flexible to use and has a high degree of automation.

[0038] In the embodiment of the present disclosure, when half of the upper limit float block 403 is submerged in water, the sum of the buoyancy generated by the upper limit float block 403 and the lower limit float block 303 is greater than the suction force of the magnetic suction block 2012. The position of the upper limit float block 403 submerged in water is not limited to half of the block. The upper limit float block 403 of different specifications can be selected according to actual needs, but it is necessary to ensure that the maximum buoyancy generated by the upper limit float block 403 is greater than the suction force of the magnetic suction block 2012. In use, in the process of replenishing and supplying water to the inside of the breeding pond 1, the water inside the breeding pond 1 The water level will continue to rise and touch the lower limit float 303. Since the buoyancy generated by the lower limit float 303 when it is completely submerged in water is not sufficient to separate the two groups of magnetic blocks 2012 through the linkage mechanism 5, that is, Fa<Fb, the inside of the breeding pond 1 is still in a water supply and water replenishment state at this time. A force lever 4011 is provided on the side of the force seat 401, and the force lever 4011 is located directly below the control seat 301. After that, the water level continues to rise and slowly submerges the upper limit float 403. Since the force lever 4011 is located directly below the control seat 301, the water level When the water level rises and slowly submerges the upper limit float 403, the buoyancy of the upper limit float 403 will continue to increase and store energy, but at this time the buoyancy generated by the upper limit float 403 is still insufficient to drive the control seat 301 to move upward through the force lever 4011 of the force seat 401 (i.e., the buoyancy is less than the suction force of the two sets of holding magnetic blocks 2012, i.e., Fa+Fc<Fb), so that the two sets of holding magnetic blocks 2012 will still be attracted to keep the water pump power on. When the water level submerges half of the upper limit float 403, the upper limit of the water level is reached. After that, the sum of the buoyancy of the upper limit float 403 through the water body and the buoyancy of the lower limit float 303 is greater than the suction force of the two groups of retaining magnetic blocks 2012, that is, Fa+Fc>Fb, so that at this time the upper limit float 403 will drive the force lever 4011 through the linkage mechanism 5 to overcome the suction force of the two groups of retaining magnetic blocks 2012 and drive the control seat 301 to move up a distance, thereby releasing the contact relationship between the two conductive disks 2011, and then the water pump power is turned off, and the operation of supplying and replenishing water to the inside of the breeding pond 1 is terminated, with a high degree of automation.

[0039] Specific usage and function of this embodiment: In the present invention, after water is injected into the culture pond 1 through a water pump, the leech culture operation can be started. The lower limit mechanism 3 can control the lower limit position of the water level in the culture pond 1. When the water level in the culture pond 1 reaches the lower limit position, the water supply and replenishment operation can be automatically started. The upper limit mechanism 4 can control the upper limit position of the water level in the culture pond 1. When the water level in the culture pond 1 reaches the upper limit position, the water supply and replenishment operation can be stopped, so that the water level in the culture pond 1 is always within a suitable range. Under the setting of the two sets of linkage mechanisms 5, the upper and lower limits of the water level in the culture pond 1 can be freely adjusted without interfering with each other. The linkage mechanism 5 can convert the lifting action into a rotation action, and then convert the rotation action into The lower limit screw 202 is transformed into a lifting action. When the lower limit position of the water level inside the breeding pond 1 needs to be adjusted, it is only necessary to rotate the lower limit screw 202. When the lower limit screw 202 rotates, it can drive the lower limit positioning seat 302 to move up and down, thereby changing the use position of the lower limit floating block 303, that is, the lower limit position of the water level inside the breeding pond 1. When the upper limit position of the water level inside the breeding pond 1 needs to be adjusted, it is only necessary to rotate the upper limit screw 203. When the upper limit screw 203 rotates, it can drive the upper limit positioning seat 402 to move up and down, thereby changing the use position of the upper limit floating block 403, that is, the upper limit position of the water level inside the breeding pond 1. Taking the water level inside the breeding pond 1 at the upper limit position as an example, and for the sake of convenience of understanding, the maximum buoyancy generated when the lower limit floating block 303 is completely immersed is Fa, and the two groups maintain The attraction force of the magnetic block 2012 is Fb, and the buoyancy generated when the upper limit float block 403 is immersed in the water body is Fc. At this time, the conversion protrusion 2013 is located at the bottom of the conversion groove 5011, so that the control seat 301 and the force-applying seat 401 are both in a lifted state. At this time, the two conductive disks 2011 are separated from each other, and the two groups of magnetic blocks 2012 are also in a separated state and will not be attracted, so that the power supply of the water pump will not be turned on at this time, and the upper limit float block 403 is half immersed in the water body at this time. With the increase of breeding time or the artificial discharge and replacement of the water body in the breeding pond 1, the water level in the breeding pond 1 will drop. When the water level in the breeding pond 1 is still within the appropriate range (between the upper limit and the lower limit), the automatic The operation of water supply and replenishment, and at this time, due to the drop in water level, the upper limit floating block 403 will also drop with the water level. When the upper limit floating block 403 drops, the upper limit linkage protrusion 4021 will rotate under the action of the upper limit linkage groove 4031. When the upper limit floating block 403 rotates, it can drive the conversion column 501 of the same linkage mechanism 5 to rotate through the synchronization rod 502 at its top. When the conversion column 501 rotates, the conversion groove 5011 can drive the force seat 401 to move downward through the conversion protrusion 2013 to restore the lowest use position. At this time, since the lower limit floating block 303 is still submerged in water, the use position of the lower limit mechanism 3 will not change, and the water supply and replenishment operation inside the breeding pond 1 will not be triggered in advance. As the water level continues to drop, when the water level drops to the lower limit position,At this time, the lower limit floating block 303 will synchronously drop with the water level, and when the lower limit floating block 303 drops, the lower limit linkage protrusion 3021 will drive the lower limit floating block 303 to rotate through the lower limit linkage groove 3031. When the lower limit floating block 303 drops, it can drive the conversion column 501 of the same linkage mechanism 5 to rotate through the synchronization rod 502 at its top. When the conversion column 501 rotates, the conversion groove 5011 can drive the control seat 301 to move downward through the conversion protrusion 2013. When the control seat 301 moves downward, the two groups of holding magnetic blocks 2012 are attracted to each other, and the two conductive plates 2011 are mutually attracted. The water pump is connected to each other to turn on the power supply of the water pump, so that when the water level reaches the lower limit, water is automatically supplied to the culture pond 1. In the process of replenishing and supplying water to the culture pond 1, the water level inside the culture pond 1 will continue to rise and touch the lower limit float 303. Since the buoyancy generated by the lower limit float 303 when it is completely submerged in water is not sufficient to separate the two groups of magnetic blocks 2012 through the linkage mechanism 5, that is, Fa<Fb, the culture pond 1 is still in the water supply and replenishment state at this time. After that, the water level continues to rise and slowly submerges the upper limit float 403. Due to the force lever 4011 is located directly below the control seat 301, so when the water level rises and slowly submerges the upper limit float 403, the buoyancy of the upper limit float 403 will continue to increase and store energy, but at this time the buoyancy generated by the upper limit float 403 is still not enough to drive the control seat 301 to move upward through the force lever 4011 of the force seat 401 (that is, the buoyancy is less than the suction force of the two sets of holding magnetic blocks 2012, that is, Fa+Fc<Fb), so the two sets of holding magnetic blocks 2012 will still be attracted to keep the water pump power on. When the water level is submerged by half of the upper limit float 403, When the water level reaches the upper limit, the sum of the buoyancy generated by the upper limit float 403 through the water and the buoyancy of the lower limit float 303 is greater than the suction force of the two groups of holding magnetic blocks 2012, that is, Fa+Fc>Fb. At this time, the upper limit float 403 will drive the force lever 4011 through the linkage mechanism 5 to overcome the suction force of the two groups of holding magnetic blocks 2012 and drive the control seat 301 to move up a distance, thereby releasing the contact relationship between the two conductive disks 2011, and then the water pump power is turned off, and the operation of supplying and replenishing water to the inside of the breeding pond 1 is terminated.
