Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, this embodiment provides a water and electricity separation's physics experiment water circulation temperature regulating device for teaching, includes: a temperature controller 3, a water tank 11, a sensor 12, an actuator 13 and the like.
Wherein the water tank 11, the sensor 12 and the actuator 13 are located in one independent first space, and the temperature controller 3 is located in another independent second space. The two spaces are independent of each other and can be respectively supplied with independent mains power. In a specific implementation scenario, the water tank 11, the sensor 12 and the actuator 13 may be disposed in one case, and the temperature controller 3 is disposed in another case, so that the layout of water and electricity separation is formed in a spatially independent manner, so as to effectively eliminate potential safety hazards of equipment and experimenters as much as possible.
In a specific line connection relationship, one end of the sensor 12 is connected with the water tank 11, and the other end of the sensor 12 is connected with the temperature controller 3 so as to monitor the temperature and/or the liquid level of the water tank 11; one end of the actuator 13 is connected with the water tank 11, and the other end of the actuator 13 is connected with the temperature controller 3, so as to heat or cool the water tank 11. The water outlet of the water tank 11 is connected with the physical experiment device 4 for teaching.
The detection end of the sensor 12 can be arranged in the water tank 11, and the part of the sensor 12 except the detection end can be arranged outside the water tank 11, so that water and electricity separation is further realized; the heating end of the actuator 13 can be arranged in the water tank 11, and the part of the actuator 13 except the heating end can be arranged outside the water tank 11, so that water and electricity separation is further realized.
When the temperature control device works, the sensor 12 monitors the water temperature in the water tank 11 and feeds a temperature signal back to the temperature controller 3, and the temperature controller 3 controls the actuator 13 to heat or cool the water in the water tank 11 according to the temperature signal; the heated or cooled water is pumped into the experimental apparatus 4 by a pumping mechanism such as a water pump 133 to perform an experiment. In an alternative embodiment, as shown in fig. 2, the water tank 11 is connected to the experimental device 4 via a channel controller 2, and the channel controller 2 facilitates switching on or off the water path.
In practical applications, the inventor finds that when the existing water circulation temperature control device is used for repeated experiments, because no active cooling/heating measure is available or the efficiency of the cooling/heating measure is too low, once temperature change needs to be repeated (for example, the temperature gradually rises from room temperature to perform experiments, and if the temperature needs to return to room temperature again after reaching a certain high temperature), a long period of cooling time needs to be waited, so that the experimental efficiency is seriously reduced, and the course arrangement in a laboratory is not facilitated.
To this end, in a variant embodiment, shown in particular in fig. 3, the tank 11, the sensor 12 and the actuator 13 constitute a temperature-controlled tank unit 1, in which the water circulation temperature control device disclosed in the present application comprises two temperature-controlled tank units 1 and a channel controller 2. The channel controller 2 is provided with two electromagnetic valves 21 connected with the temperature controller 3, the water outlets of the two water tanks 11 are connected with one electromagnetic valve 21, the electromagnetic valve 21 can be controlled to open the water outlet of one water tank 11 and close the water outlets of the other water tanks 11, the water inlets of the two water tanks 11 are connected with the other electromagnetic valve 21, and the electromagnetic valve 21 can be controlled to open the water inlet of the one water tank 11 and close the water inlets of the other water tanks 11.
Specifically, as illustrated in fig. 3, the working principle of the scheme is further explained:
the water outlet of the left water tank 11 is connected with a left electromagnetic valve 21 in the channel controller 2, and the electromagnetic valve 21 can be controlled to open the water outlet of the left water tank 11 and close the water outlet of the right water tank 11, but the opposite can be true; the inlet of the left water tank 11 is connected to the right solenoid valve 21 of the channel controller 2, and the solenoid valve 21 can be controlled to open the inlet of the left water tank 11 and close the inlet of the right water tank 11, but the opposite is also possible.
In this embodiment, the two temperature control water tank units 1 are used in cooperation with the two electromagnetic valves 21, the electromagnetic valves 21 can be multi-way (multi-way) valves, that is, a plurality of water paths are formed among the temperature control water tank units 1, the path controllers 2 and the experimental device 4, the temperature controller 3 controls the on-off of the water paths by controlling the on-off of the electromagnetic valves 21, so that the water paths are freely switched, and the circulating water in the experimental device is immediately changed by preferentially selecting or switching to other water tanks 11 before or during an experiment.
In another alternative embodiment, referring to fig. 4, the present device may not use the channel controller 2, but only remain the electromagnetic valve 21, and also may perform the function of switching the water channel, specifically:
the water tank 11, the sensor 12 and the actuator 13 form a temperature control water tank unit 1, the device comprises two temperature control water tank units 1 and two electromagnetic valves 21, and the two electromagnetic valves 21 are electrically connected with the temperature controller 3;
wherein the content of the first and second substances,
the water outlet of each of the two water tanks 11 is connected to one of the solenoid valves 21, the solenoid valve 21 is controlled such that the water outlet of one of the water tanks 11 is open and the water outlets of the remaining water tanks 11 are closed, the water inlet of each of the two water tanks 11 is connected to the remaining one of the solenoid valves 21, and the solenoid valve 21 is controlled such that the water inlet of one of the water tanks 11 is open and the water inlets of the remaining water tanks 11 are closed. For the specific working mode, refer to the working modes of the left water tank 11 and the right water tank 11 in the foregoing embodiments, and are not described again.
Likewise, in other alternative embodiments,
the electromagnetic valve 21 in the foregoing embodiment may also be replaced by a manual valve 22, and the specific scheme is as follows:
the water tank 11, the sensor 12 and the actuator 13 form a temperature control water tank unit 1, and the water-electricity separated water circulation temperature control device for the teaching physical experiment comprises two temperature control water tank units 1 and two manual valves 22;
wherein the content of the first and second substances,

The specific operation is described in the previous embodiment with reference to the operation of the left water tank 11 and the right water tank 11.
In the above embodiment, the working principle is mainly illustrated by two water tanks 11, and when there are multiple water tanks 11, the working principle is the same as that of two water tanks 11, and it is not described again, and those skilled in the art can correspondingly select the electromagnetic valve 21 or the manual valve 22 according to the number of the water tanks that are changed.
Further, the temperature controller 3 can adopt a temperature controller with a key switching function, and the temperature controller with the function can set and select the target temperature control water tank unit 1 through a screen or keys of the temperature controller, that is, the temperature controller 3 can control the electromagnetic valve 21 and the water pump 133, and a water path and a circuit are synchronously switched between different temperature control water tank units 1 by one key, so that convenience and safety of an experiment can be improved. The temperature controller 3 can be used for manually setting parameters and carrying out PID automatic control, and the description is not described herein; the signal transmission can be realized by circuit connection lines such as electric wires and signal wires, which are not described herein.

In this embodiment, water is supplied to the experimental apparatus 4 in a water circulation manner, so that the temperature of the water flowing through the experimental apparatus 4 can be effectively controlled within a temperature range required for the experiment.
The above examples are based on water and electricity separation, with the difference that there is no channel controller 2 in one embodiment and a channel controller 2 in another embodiment. When the channel controller 2 is not provided, the channel controller can be directly connected with the experimental device 4 through the temperature control water tank unit 1, the water outlet of the water tank 11 is connected with the water inlet of the experimental device 4, and the water outlet of the experimental device 4 is connected with the water inlet of the water tank 11 to form water circulation. The scheme is suitable for the occasions of a single temperature control water tank unit 1 or a plurality of temperature control water tank units 1 without one-key switching function.
In another aspect of practical application, the inventor finds that, in a water tank of an existing water circulation temperature control device, because frequent replacement of circulating water is not considered, the water tank is closed (generally, only a small water filling port is reserved), which causes that water scales in the water tank can be cleaned only after a water tank cover is removed, which brings great inconvenience to maintenance, and meanwhile, the closed water tank causes that conventional operations such as water bath cannot be performed, and the universality is poor.
For this purpose, in some embodiments, the upper end of the water tank 11 is open and is provided with a water filling port, and the effective water filling sectional area is greater than or equal to 120cm 2 Meanwhile, the water tank 11 is provided with a movable water tank cover, so that the water tank 11 is convenient to clean and maintain, and the water tank can be used as a general water bath device, for example, a unit to be measured (such as a test tube, a beaker and the like) which needs temperature control can be directly arranged in the water tank 11, and the temperature of the unit to be measured is controlled in a water bath-like mode.

The heating end of the electric heater 131 can be arranged in the water tank 11, and the part of the electric heater 131 except the heating end can be arranged outside the water tank 11, so that water and electricity separation is further realized; the fan 132 may be disposed at the side, bottom or top of the water tank 11, and an air inlet end of the fan 132 may face outward and an air outlet end thereof faces inward, for introducing external cold air into the water tank 11 to cool; or the air outlet end of the fan 132 may face outward and the air inlet end faces inward, for discharging the hot air in the water tank 11 to the outside for cooling. In some implementation scenarios, there may be 2 fans 132, where the air inlet end of one fan 132 faces outwards and the air outlet end faces inwards, and the air outlet end of the other fan 132 faces outwards and the air inlet end faces inwards. In other implementation scenarios, the actuator 13 includes a semiconductor refrigeration sheet, the semiconductor refrigeration sheet is disposed on the water tank 11, and the semiconductor refrigeration sheet is used for cooling the water tank 11. The semiconductor refrigeration piece can be used as an alternative or combination of the fan 132, that is, the semiconductor refrigeration piece can be used together with the fan 132 to cool the water tank 11.
As shown in fig. 7, the actuator 13 may further include a water pump 133, one end of the water pump 133 is connected to the water tank 11, and the other end is directly connected to the teaching physical experiment device 4, or connected to the teaching physical experiment device 4 through the channel controller 2 to deliver water. In some implementation scenarios, the water tank 11 is provided with a drain valve, and the water tank 11 discharges water through the drain valve, so that maintenance and water change are facilitated; the water pump 133 is arranged at one side outside the water tank 11, so that water and electricity separation is further realized; one end of the water pump 133 is connected to a water outlet of the water tank 11, and the other end is connected to a water inlet of an input end of the passage controller 2 to deliver water.

If all parameters are not abnormal in self-checking, an experimenter can set and select one of the temperature control water tank units 1 and the target temperature and other parameters, after confirmation, the temperature controller 3 automatically sends related instructions to the channel controller 2 and the selected temperature control water tank unit 1 through a one-key switching function, the channel controller 2 controls the internal electromagnetic valve 21 to enable the selected temperature control water tank unit 1 to be communicated with the water channel of the experimental device 4, then the water pump 133 in the selected temperature control water tank unit 1 starts to work, and the water channel in the water tank 11 is enabled to be:

Meanwhile, the electric heater 131 generates heat through controlled current according to instructions to further change the water temperature in the water tank 11, the temperature sensor 121 measures the water temperature in the water tank 11 and feeds a temperature signal back to the temperature controller 3, and the current passing through the electric heater 131 is controlled after the temperature controller 3 automatically analyzes the temperature signal, so that closed-loop control of the water temperature in the water tank 11 is formed. The temperature-controlled water in the water tank 11 flows through the experimental device 4 through the circulating water path, so that the temperature of the water at the experimental device 4 is controlled, and the temperature of the relevant unit to be tested of the experimental device 4 can be controlled through heat transfer. The experimental device 4 is used for teaching physical experiments requiring temperature control, including but not limited to viscosity coefficient experiments and metal wire expansion experiments.
If the temperature of the water in a certain temperature-controlled water tank unit 1 is increased to a higher temperature (far from the room temperature), and the experiment needs to be gradually increased again from a lower temperature (close to the room temperature), it will take a long time if the temperature of the water in the temperature-controlled water tank unit 1 is decreased from the higher temperature to the lower temperature.
