Description

Technical Field

[0001] This utility model relates to the field of biological simulation experimental equipment technology, and in particular to an aquatic ecosystem simulation device for biological experiments. Background Technology

[0002] Temperature and light are crucial factors in aquatic ecosystems, directly affecting the growth, reproduction, and survival of aquatic organisms. Therefore, indoor biological experiments require strict control of temperature, light, and other conditions during the experimental process. As a result, water bath temperature control systems or greenhouse systems are commonly used in simulation experiments. Conventional water bath temperature control systems include constant temperature water baths, which can simulate the temperature environment in aquatic ecosystems.

[0003] The utility model disclosed in CN205236001U is a constant temperature controlled water bath, including a tank body, a water tank inside an open tank on the body, an insulation layer sandwiched between the water tank and the body body, a temperature control device and a stirring device at the bottom of the water tank, and a perforated grate above the stirring device; a water inlet pipe at the top of the tank body with a water inlet valve at the inlet of the water inlet pipe; a water outlet pipe at the bottom of the water tank with a water outlet valve at the outlet of the water outlet pipe; a heating device and a cooling device connected to the water tank; and a controller on one side of the body, which is connected to a display and input panel.

[0004] As described above, when using a constant temperature water bath, the experimental container needs to be placed in the water bath and then removed after the experiment. Since there is water in the water bath, it is inconvenient to take the experimental container out of the water bath. In order to solve the above technical problems, it is necessary to provide a circulating water bath temperature control system that makes it easier to take out and place the experimental container.

[0049] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0050] like Figure 1-5As shown, this utility model discloses an aquatic ecosystem simulation device for biological experiments, comprising a water tank 1, a platform 2, a linear drive mechanism 3, a vibration mechanism 4, an outlet pipe 5, a moving trolley 6, a heating / cooling unit 7, and a circulation pump 8.

[0051] Water is contained in the water tank 1, and the experimental container is placed on the platform 2, which keeps the experimental container submerged in the water. Specifically, the platform 2 includes a grid plate 21 and rollers 22. The grid plate 21 is located inside the water tank 1, and the rollers 22 are rotatably mounted on both sides of the grid plate 21 and are rolled against the walls of the water tank 1. The output end of the linear drive mechanism 3 is fixedly connected to the bottom of the grid plate 21, and the linear drive mechanism 3 drives the platform 2 to slide vertically inside the water tank 1. To facilitate the installation of the rollers 22, U-shaped grooves are provided on both sides of the grid plate 21 at the positions corresponding to the rollers 22. The rollers 22 are rotatably mounted in the corresponding U-shaped grooves. Figure 3 As shown, four rollers 22 are arranged in a matrix, the grid plate 21 is made of stainless steel and is square in shape, and the water tank 1 is also a square tank.

[0052] One end of the linear drive mechanism 3 is fixedly installed at the bottom of the water tank 1. The output end of the linear drive mechanism 3 extends vertically through the bottom of the water tank 1 and is fixedly connected to the bottom of the platform 2. It is used to drive the platform 2 to rise and fall. By rising and falling, the platform 2 rises above the water surface, making it convenient to put and take experimental containers on the platform 2. Specifically, the linear drive mechanism 3 includes a mounting base 31 and a telescopic rod 32. The mounting base 31 is fixedly installed at the bottom of the water tank 1. One end of the telescopic rod 32 is fixedly installed at the bottom of the mounting base 31. The output shaft of the telescopic rod 32 passes through the water tank 1 and is fixedly connected to the grid plate 21. The telescopic rod 32 is an electric push rod or a telescopic cylinder. When the telescopic rod 32 extends, it pushes the platform 2 to rise. When the telescopic rod 32 shortens, it drives the platform 2 to fall. When the platform 2 rises and falls, the roller 22 rolls along the wall of the water tank 1.

[0053] Because the experimental container is submerged in water during the experiment, a significant amount of water remains on its surface after the container rises above the water level on platform 2. This water can cause slippage when handling the container. To address this issue, a vibration mechanism 4 is fixedly installed on the inner side of the top of the water tank 1. When platform 2 rises, one end of the vibration mechanism 4 rests against the top of platform 2, vibrating the platform to drain the water from the container, making it easier to handle and reducing slippage. When platform 2 descends, the vibration mechanism 4 ceases to contact platform 2. The vibration mechanism 4 is provided on both sides of the top of the water tank 1. The vibration mechanism 4 includes a mounting plate 41, a damping spring 42 and a vibration motor 43. The mounting plate 41 is fixedly installed on the top of the inner side of the water tank 1. One end of the damping spring 42 is fixedly installed on the bottom of the mounting plate 41, and the other end of the damping spring 42 is fixedly connected to the vibration motor 43. The vibration motor 43 is located between the mounting plate 41 and the grid plate 21. After the platform 2 is raised, the damping spring 42 can make the vibration motor 43 elastically abut against the platform 2 to improve the vibration effect and thus improve the drainage effect.

[0054] For easy movement, the mobile trolley 6 is fixedly installed at the bottom of the water tank 1. Specifically, the mobile trolley 6 includes a base 61, wheels 62, and a support frame 63. Several wheels 62 are fixedly installed at the bottom of the base 61. The support frame 63 is located between the base 61 and the water tank 1. One end of the support frame 63 is fixedly connected to the bottom of the water tank 1, and the other end is fixedly connected to the top of the base 61. The wheels 62 are omnidirectional wheels. The support frame 63 consists of multiple vertical rods. Through the support of the support frame 63, a storage space is formed between the base 61 and the water tank 1 for placing the heating / cooling unit 7 and the circulation pump 8.

[0055] The heating / cooling unit 7 and the circulating pump 8 are both fixedly mounted on the base 61. The outlet of the heating / cooling unit 7 and the inlet of the circulating pump 8 are connected by a pipe. The bottom of the water tank 1 is provided with a water outlet 103 and a water return hole 104. The inlet of the heating / cooling unit 7 is connected to the water outlet 103 by a pipe, and the outlet of the circulating pump 8 is connected to the water return hole 104 by a pipe.

[0056] Specifically, the heating and cooling unit 7 includes a constant temperature water heater and a semiconductor refrigeration module. The constant temperature water heater adopts any type of constant temperature electric water heater in the prior art, such as the constant temperature electric water heater disclosed in CN103954034A. The constant temperature water heater has a water tank with an inlet and an outlet. The outlet 103 of the water tank 1 and the inlet of the water tank are connected by a pipe. The outlet of the water tank and the inlet of the circulation pump 8 are connected by a pipe. When the constant temperature water heater is working, it heats the water in the water tank. At this time, the circulation pump 8 is used to form circulating hot water. Through circulation, the water in the water tank 1 enters the water tank for heating, and then the circulating pump 8... The water is fed into the water tank 1, turning the water in the water tank 1 into hot water. The semiconductor cooling module can be any of the existing technologies, such as the DTA-28-12-24 semiconductor cooling component. An opening is made on one side of the water tank, and the semiconductor cooling module is fixed on the water tank. The cold end of the semiconductor cooling module is fixed in the opening and sealed to prevent water leakage, so that the cold end is in contact with the water in the water tank. When it is necessary to cool the water in the water tank, the semiconductor cooling module is powered on, and the water is cooled by cooling through the cold end. At this time, the circulation pump 8 is used to circulate cold water, so that the water in the water tank 1 becomes low-temperature water. The specific structure of the heating and cooling unit 7 is not shown in the illustration.

[0057] To maintain the water level in the water tank 1 and to facilitate sewage discharge, an overflow hole 101 is horizontally installed on one side of the top of the water tank 1, and the overflow hole 101 is located below the vibration mechanism 4. A sewage discharge hole 102 is horizontally installed on one side of the bottom of the water tank 1. One outlet pipe 5 is fixedly installed at each of the overflow hole 101 and the sewage discharge hole 102. Both outlet pipes 5 are connected to the sewage tank through pipes. A valve is installed on the outlet pipe 5 at the sewage discharge hole 102 to control sewage discharge.

[0058] The indoor simulation experiment requires control of the lighting conditions during the experiment. Therefore, a fluorescent lamp 9 is installed above the water tank 1 to provide illumination, which facilitates control of the illumination time. The fluorescent lamp 9 adopts any type of LED lamp with adjustable brightness in the prior art, which facilitates control of the light intensity, such as a dimming LED fluorescent lamp disclosed in CN101694268A. The specific structure can be found in the prior art.

[0059] The fluorescent lamp 9 is connected to the water tank 1 using a gooseneck tube. Therefore, the characteristics of the gooseneck tube can be used to easily adjust the position of the fluorescent lamp 9, which is quite convenient.

[0060] The method of using the aquatic ecosystem simulation device for biological experiments according to this invention is as follows:

[0061] First, the system is moved to the experimental area by the mobile trolley 6, an appropriate amount of water is injected into the water tank 1, and the heating / cooling machine 7 and the circulating pump 8 are started to heat or cool the water to the required temperature.

[0062] During the experiment, the platform 2 is driven to rise by the linear drive mechanism 3. After rising, the experimental container that needs a water bath is placed on the platform 2. Then, the platform 2 is driven to fall by the linear drive mechanism 3 so that the liquid level in the water bath is above the liquid level in the experimental container or the upper surface of the experimental matrix.

[0063] After the experiment, the linear drive mechanism 3 drives the platform 2 to rise and make the platform 2 contact the vibration mechanism 4. At this time, the experimental container rises above the water surface, and the vibration motor 43 is started to vibrate the platform 2 to drain the water from the experimental container. After draining, the experimental container is removed from the platform 2.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
