Description

Technical Field

[0001] The invention relates to the technical field of amphibian breeding, in particular to a water quality detection and sampling device for amphibian breeding. Background Art

[0002] Amphibians are animals that live in water and on land, and they adapt to different living environments at different stages of their life cycle. The main characteristics of amphibians include: Larvae live in water: Amphibian larvae (such as tadpoles) usually live in water and breathe through gills, Adults are amphibious: Adults can live on land or in water, and mainly breathe through skin and lungs, Moist skin: Amphibians usually have moist skin, which helps them breathe and retain water, Metamorphosis: Amphibians undergo significant changes from larvae to adults during their life cycle, a process called metamorphosis, Cold-blooded: Amphibians are cold-blooded animals, and their body temperature changes with the temperature of the environment, Egg-laying reproduction: Amphibians usually lay eggs in water, and the eggs are protected by a layer of gelatinous substance. Common amphibians include frogs, toads, salamanders and giant salamanders. Amphibians are an important group of vertebrates, and are of great significance to the balance of ecosystems and the conservation of biodiversity.

[0003] The water quality at different depths is different, and sampling is also required for detection, so that the staff can clearly detect and understand the changes and composition of water quality, and detect water quality more accurately. The existing public patent (publication number is CN118533561A) discloses a water quality detection sampling device for frog breeding, including a sampling rod, a connecting hose is fixedly provided on the top of the sampling rod, and a float is fixedly provided on one side of the top of the connecting hose. This kind of water quality detection sampling device for frog breeding, through the cooperation between the arc-shaped air plug and the air hood, the air cavity inside the sampling rod is reduced and the buoyancy is reduced, so that the sampling rod sinks in the pool, and vice versa, the air cavity is expanded and the sampling rod floats. Compared with the existing water suction pool, the water in the upper and lower hard tubes can be controlled to control the size of the air cavity as the source of buoyancy, and the floating and sinking of the sampling rod can be realized accordingly. There is no need to introduce external water into the equipment. On the one hand, it can avoid the adhesion of debris in the water to the inside of the equipment to cause pollution, and on the other hand, it can avoid the increase of mass beyond the range caused by the inhalation of solid debris with different densities, and avoid uncontrollable sinking. In the above-mentioned comparative patent, sinking and floating are realized by the cooperation between the arc-shaped air plug and the air hood. However, in the process of sampling, this method can only obtain water samples of a single depth. When it is necessary to obtain multiple water samples at different heights, it is necessary to repeat the sampling work continuously, which is labor-intensive and reduces the efficiency of water quality detection. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides a water quality detection sampling device for amphibian breeding, which solves the problem that when obtaining water samples at multiple different heights, the sampling work needs to be repeated continuously, resulting in a large workload and reduced water quality detection efficiency.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a water quality detection and sampling device for amphibian breeding, comprising a control mechanism, a lower connecting frame is fixedly arranged at the lower end of the control mechanism, a storage frame is fixedly arranged inside the lower connecting frame, a side limit cylinder is penetrated through the lower end of one side of the storage frame, a recovery handle is slidably penetrated through the middle position of the front end of the storage frame, a layered sampling mechanism is wound around the storage frame, one end of the layered sampling mechanism is fixedly connected to the recovery handle, and the other end of the layered sampling mechanism is slidably sleeved inside the side limit cylinder;

[0008] The stratified sampling mechanism includes an elastic pipe with multiple sampling ports opened inside the elastic pipe, and lifting cylinders are slidably arranged inside the elastic pipe near the multiple sampling ports, and upper pull ropes are fixedly arranged on the upper ends of the multiple lifting cylinders, and internal connecting frames are fixedly arranged inside the multiple lifting cylinders, and a pull-down spring is fixedly arranged on the lower end of an internal connecting frame at the lowest end of the multiple lifting cylinders.

[0009] Preferably, the upper ends of the plurality of upper pull ropes are fixedly connected to the inner connecting frame inside the upper end lifting cylinder thereof, and the uppermost one of the plurality of upper pull ropes is fixedly connected to the recovery handle.

[0010] Preferably, a plurality of rubber sealing pads are provided through the bodies of the plurality of lifting cylinders, and the plurality of rubber sealing pads are at the same level and have the same size as the plurality of sampling ports.

[0011] Preferably, the control mechanism includes a support frame, a control button is slidably provided on the top of the support frame, an extrusion block is slidably provided on one side of the lower end of the support frame, a return spring is fixedly connected between the extrusion block and the inside of the support frame, a transmission line is fixedly provided on the extrusion block near one side of the support frame, and the other end of the transmission line is fixedly connected to the control button.

[0012] Preferably, the extrusion block is located away from the support frame and penetrates through the side limiting cylinder to contact the layered sampling mechanism.

[0013] Preferably, auxiliary frames are hingedly provided at the front and rear ends of the control mechanism, and an auxiliary handle is fixedly provided at the middle position of the upper end of the control mechanism.

[0014] Preferably, a limit sealing ring is fixedly provided at the bottom of the elastic pipe, a gravity block is fixedly provided at the lower end of the limit sealing ring, and the lower end of the pull-down spring is fixedly connected to the upper end of the limit sealing ring.

[0015] Working principle: When using this sampling device, first unfold the auxiliary frames on both sides so that the device can be supported above the designated sampling position, and then release the stratified sampling mechanism of the designated length according to the sampling requirements. During the sampling process, the staff first presses the control button to move it downward, which will drive the transmission line to move during the movement. Then the extrusion block connected to the transmission line will be driven and squeeze the reset spring to start moving to one side. At this time, the limit of the stratified sampling mechanism by the extrusion block will be cancelled, and then the recovery handle can be turned to drive the stratified sampling mechanism wound inside the storage frame to rotate;

[0016] When the stratified sampling mechanism rotates, its wound part will unfold outward along the side limit cylinder, and then under the action of the gravity block, the elastic pipe will move vertically downward and slowly enter the water surface to be sampled. At this time, it will rotate a specified number of times according to the sampling needs, so that the length of the elastic pipe entering the water surface is equal to the depth required for sampling. At this time, the recovery handle can be pulled to one side. Since the recovery handle is slidably arranged inside the lower connecting frame and connected to the upper pull rope at the top, multiple lifting cylinders will be driven to move upward in the process of pulling the recovery handle. At this time, multiple lifting cylinders move upward inside the elastic pipe and suck water near the depth of each lifting cylinder into the elastic pipe through the sampling port. Then release the recovery handle. At this time, multiple lifting cylinders will reset under the action of the pull-down spring, and the sampling port on the elastic pipe will be sealed during the reset, thereby completing the sampling work and completing the rapid sampling of water samples at various depths.

[0017] After the sampling is completed, the water to be tested at each depth is sealed inside the multiple lifting cylinders. At this time, the recovery handle is rotated in the opposite direction to reel the stratified sampling mechanism into the storage frame again. Then the control button is released to make the limit column lose its tension and then be squeezed by the reset spring again to the stratified sampling mechanism. At this time, the auxiliary frame can be folded up and the device can be carried by the auxiliary handle to move to the detection mechanism for detection, which is convenient for movement.

[0018] When it is necessary to take out a water sample in the detection mechanism, the layered sampling mechanism can be released again, and a water sample of a specified depth can be obtained according to the location of the sampling port. During the process of taking out the water sample, the water sample can be drawn out by inserting an injection agent into the rubber sealing pad. During this period, the lifting cylinder and the elastic pipe always seal the water sample in layers inside, thereby ensuring that the water sample will not be contaminated from the time of taking out to the time of detection;

[0019] After the test is completed, the layered sampling mechanism can be unfolded and the recovery handle can be pulled to unfold the lifting cylinder and the elastic pipe through the sampling port, thereby facilitating the cleaning of the interior.

[0020] (III) Beneficial effects

[0021] The present invention provides a water quality detection and sampling device for amphibian breeding, which has the following beneficial effects:

[0022] 1. The present invention provides a water quality detection and sampling device for amphibian breeding. During the detection process of the device, an elastic pipe is unfolded and penetrates into the water surface to be sampled. According to the sampling requirements, the elastic pipe rotates a specific number of times to reach the required depth. Subsequently, the recovery handle on one side is pulled, and the handle slides inside the lower connecting frame and is connected to the upper pull rope. When the recovery handle is pulled, multiple lifting cylinders move upward accordingly. These lifting cylinders rise inside the elastic pipe and absorb water samples near the depth of each lifting cylinder through the sampling port. After releasing the recovery handle, the lifting cylinder resets under the action of the pull-down spring, and closes the sampling port on the elastic pipe during the resetting process, thereby completing the sampling process. The device realizes the rapid sampling of water samples at various depths, significantly improving the sampling efficiency.

[0023] 2. The present invention provides a sampling device for testing water quality for amphibian breeding. After completing the sampling procedure, the device can seal water samples to be tested at different depths in multiple lifting cylinders. Subsequently, the stratified sampling mechanism can be rewound into the storage frame by rotating the recovery handle in reverse. After releasing the control button, the limit column is pushed back to a position close to the stratified sampling mechanism by the reset spring due to the loss of tension. At this time, the auxiliary frame can be folded up, and the device can be carried to the testing site for subsequent analysis by the auxiliary handle, thereby achieving convenient mobility. In the process of extracting water samples, a syringe is used to penetrate the rubber sealing pad to draw out the water sample. During the whole process, the lifting cylinder and the elastic pipe ensure the stratified sealing of the water sample, effectively preventing the contamination of the water sample during the extraction to the detection process, thereby improving the accuracy of the test results.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments 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.

[0031] like Figure 1 and 2 As shown, an embodiment of the present invention provides a water quality detection and sampling device for amphibian breeding, including a control mechanism 2, a lower connecting frame 4 is fixedly provided at the lower end of the control mechanism 2, a storage frame 6 is fixedly provided inside the lower connecting frame 4, a side limiting cylinder 7 is penetrated at the lower end of one side of the storage frame 6, a recovery handle 5 is slidably provided through the middle position of the front end of the storage frame 6, a layered sampling mechanism 8 is wound around the storage frame 6, one end of the layered sampling mechanism 8 is fixedly connected to the recovery handle 5, and the other end of the layered sampling mechanism 8 is slidably sleeved inside the side limiting cylinder 7, auxiliary frames 3 are hingedly provided at the front and rear positions of the control mechanism 2 and close to the upper end, and an auxiliary handle 1 is fixedly provided at the middle position of the upper end of the control mechanism 2;

[0032] Specifically, in the above-mentioned specific embodiment, in the process of operating the sampling device, it is first necessary to unfold the auxiliary brackets on both sides of the device to ensure that the device can be firmly supported above the predetermined sampling position. Subsequently, according to the actual sampling needs, the stratified sampling mechanism of the required length can be released. During the sampling process, the operator can rotate the recovery handle 5 to drive the stratified sampling mechanism wrapped inside the storage frame 6 to rotate. This design makes it more convenient to release the stratified sampling mechanism of a specified length, and can easily enter the inside of the water surface to be tested. In this way, the efficiency and convenience of sampling are significantly improved.

[0033] like Figure 1-3As shown, the control mechanism 2 includes a support frame 203, a control button 201 is slidably provided on the top of the support frame 203, a squeeze block 204 is slidably provided on one side of the lower end of the support frame 203, a return spring 205 is fixedly connected between the squeeze block 204 and the inside of the support frame 203, a transmission line 202 is fixedly provided at a position of the squeeze block 204 close to one side of the support frame 203, the other end of the transmission line 202 is fixedly connected to the control button 201, and the squeeze block 204 is away from the side of the support frame 203 and penetrates the side limit cylinder 7 to contact the layered sampling mechanism 8;

[0034] Specifically, in the above-mentioned specific embodiment, during the sampling operation, the staff can move the sampling device downward by pressing the control button 201. As the device descends, the transmission line 202 will also move accordingly, because the transmission line 202 is connected to the extrusion block 204, so the extrusion block 204 will also be driven. When the extrusion block 204 starts to move, it will squeeze the return spring 205 to move it to one side. In this process, the limiting effect of the extrusion block 204 on the stratified sampling mechanism 8 will be cancelled, so that the stratified sampling mechanism 8 can be smoothly deployed. In addition, such a design also greatly facilitates the carrying of the device during movement, avoids the possibility of the stratified sampling mechanism 8 being scattered, thereby ensuring the smooth progress of the sampling process.

[0035] like Figure 4 and 5 As shown, the layered sampling mechanism 8 includes an elastic pipe 806, a plurality of sampling ports 805 are provided inside the elastic pipe 806, a lifting cylinder 802 is slidably provided near the plurality of sampling ports 805 inside the elastic pipe 806, a pull rope 801 is fixedly provided at the upper end of the plurality of lifting cylinders 802, an inner connecting frame 809 is fixedly provided inside the plurality of lifting cylinders 802, a pull-down spring 804 is fixedly provided at the lower end of an inner connecting frame 809 at the lower end of the plurality of lifting cylinders 802, and the upper ends of the plurality of pull ropes 801 are fixedly connected to the inner connecting frame 809. The inner connecting frame 809 is connected to the inner part of the upper lifting cylinder 802, and the uppermost one of the multiple upper pull ropes 801 is fixedly connected to the recovery handle 5. The multiple lifting cylinders 802 are all provided with multiple rubber sealing pads 803, and the multiple rubber sealing pads 803 are at the same level and size as the multiple sampling ports 805. A limit sealing ring 807 is fixedly provided at the bottom of the elastic pipe 806, and a gravity block 808 is fixedly provided at the lower end of the limit sealing ring 807. The lower end of the pull-down spring 804 is fixedly connected to the upper end of the limit sealing ring 807.

[0036] Specifically, in the above-mentioned specific embodiment, during the sampling process of the stratified sampling mechanism 8, when the mechanism rotates, the winding part will be unfolded outward along the side limit tube 7. Subsequently, under the action of the gravity block 808, the elastic pipe 806 moves vertically downward and gradually penetrates into the water surface to be sampled. At this stage, according to the sampling requirements, a specific number of turns are rotated so that the length of the elastic pipe 806 that penetrates into the water surface reaches a predetermined depth. At this time, the recovery handle 5 is pulled to one side. Since the recovery handle 5 is slidingly arranged inside the lower connecting frame 4 and is connected to the upper pull rope 801 at the top, pulling the recovery handle 5 will drive multiple lifting cylinders 802 to move upward. These lifting cylinders 802 move upward inside the elastic pipe 806, and the water near the depth of each lifting cylinder 802 is sucked into the elastic tube through the sampling port 805. Then, the recovery handle 5 is released, and the multiple lifting cylinders 802 are reset under the action of the pull-down spring 804, and the sampling port 805 on the elastic pipe 806 is closed during the reset process, thereby completing the sampling work. Through this method, rapid sampling of water samples of various depths is achieved. After sampling is completed, the water to be tested at each depth is enclosed in multiple lifting cylinders 802. At this time, the recovery handle 5 is rotated in the opposite direction to rewind the stratified sampling mechanism 8 into the storage frame 6. Next, the control button 201 is released to make the limit column lose its tension, and then it is squeezed again by the reset spring 205 to be close to the stratified sampling mechanism 8. At this time, the auxiliary frame 3 can be folded up and the auxiliary handle 1 can be carried by hand, and the device can be carried to the detection mechanism for detection, which significantly improves the convenience of movement. When the water sample needs to be taken out in the detection mechanism, the stratified sampling mechanism 8 can be released again, and the water sample of the specified depth can be obtained according to the position of the sampling port 805. In the process of taking out the water sample, the water sample is extracted by inserting a syringe into the rubber sealing pad 803. During this period, the lifting cylinder 802 and the elastic pipe 806 always seal the water sample in layers inside, ensuring the pollution-free state of the water sample from taking out to detection. After the detection is completed, the stratified sampling mechanism 8 can be unfolded and the recovery handle 5 can be pulled to unfold the lifting cylinder 802 and the elastic pipe 806 through the sampling port 805, which is convenient for cleaning the inside.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
