FIG. 1 is a schematic flow chart of an embodiment of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings and examples.
In the transportation, it can receive jolting to transport the water tank, the collision, thereby cause the damage to the water tank and take place the damage even and reveal, lead to incasement water pressure unbalance, cause great economic loss to the transportation of aquatic products, and the container incasement loads a plurality of water tanks, polytype water tank even, the water tank can't carry out unified management, the predetermined pressure of carrying of each water tank is all different, can't carry out accurate measurement and control, often not can not perceive after taking place the damage phenomenon, only just can discover when checking the goods, but has caused great loss this moment.
The first embodiment is as follows: as shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a tank pressure control method for freshwater fish, comprising the following steps:
s1: a connecting spring is arranged between the moving plate and the fixed plate;
the two plate bodies are arranged, one plate body is fixedly arranged, one plate body is displaced under the action of pressure, and the connecting spring plays a role in assisting displacement.
Here, the moving plate is displaced toward the fixed plate by the pressure to compress the spring, and the moving plate returns to the original position by the spring force of the spring due to the absence of the pressure.
The pressure is converted into the displacement, the problem of nonuniform pressure caused by different sizes of the water tanks is solved, and whether the environmental pressure of the movable plate is balanced or not can be known only by knowing the displacement change of the movable plate under the pressure.
It is to be noted that the number of the connecting springs is at least three. And the connecting springs are arranged at different heights, so that the pressure on each connecting spring is different.
S2: fixing the fixing plate to the side wall of the water tank;
two plate bodies can detect pressure balance, and the measurement to the water tank should detect the lateral wall of water tank, installs so on the lateral wall, and the displacement of movable plate just can be direct whether the pressure of measuring the water tank lateral wall is balanced.
It is of course noted that the fixing plate is fixed to either the inner or outer side wall of the tank.
If the fixed plate is fixed to the inner side wall of the water tank, the movable plate is displaced under the pressure of the water body in the water tank, and the pressure of the water body in the water tank is monitored and controlled.
If the fixed plate is fixed to the outer side wall of the water tank, the movable plate is subjected to extrusion force of an object outside the water tank to generate displacement, and collision, bump and shaking amplitude outside the tank are monitored and controlled.
S3: an infrared transmitter is arranged at the end part of the moving plate, and an infrared receiver is arranged on the moving plate;
the bending of the moving plate is detected, and the bending of the moving plate is indicated when the infrared receiver does not receive the infrared ray emitted by the infrared emitter.
S4: the infrared receiver judges whether the infrared signal can not be received; if so, sending out an alarm; otherwise, the method is safe.
It was also mentioned above that the number of connecting springs is at least three. And the connecting springs are arranged at different heights, so that the pressure on each connecting spring is different. Due to the basic characteristics of water, the water depth is in direct proportion to the pressure, when the movable plate is in a water body on the inner wall of the water tank, the displacement quantity of the movable plate part at different depths is different, but the displacement quantity is still in direct proportion to the water depth, so that the movable plate cannot be bent, and the displacement quantity of the movable plate is also controlled by the spring.
Because the water characteristics, the water depth and the pressure are in direct proportion, under the influence of the water pressure, the displacement of each part under the pressure is also in direct proportion, namely, the moving plate does not bend, and if the moving plate bends, the direct proportion characteristics of the water depth and the pressure in the water are damaged, namely, the pressure is unbalanced.
In addition, if the fixed plate is installed on the outer wall of the water tank, if the fixed plate is extruded in a plane, the pressure on the movable plate is also balanced, if the fixed plate is extruded by a sharp object, the water tank can be damaged, and if part of the movable plate is extruded and other parts of the movable plate are not extruded, the movable plate can be bent to react to external abnormal extrusion force.
In a word, once the infrared receiver cannot receive the infrared rays emitted by the infrared emitter, the movable plate is bent, the pressure imbalance of the water tank is indicated, the damage risk or even the damage phenomenon exists, the alarm is given out, and the pressure control is carried out.
In the method, the types of the water tanks are changed, but the characteristics of water are not changed, the water depth is directly proportional to the pressure, the phenomenon that the moving plate is displaced and the water depth is directly proportional is converted into an observable phenomenon, and then whether the moving plate is bent or not is observed to judge whether the water pressure is abnormally changed, so that the method can be adopted to carry out pressure control on any water tank.
The invention is not only simple, practical, reasonable and effective, and has high pressure balance measurement accuracy, but also can control the pressure of various water tanks.
Example two: still referring to fig. 1, which is only one embodiment of the present invention, in order to achieve better effect of pressure control of the tank pressure control method for freshwater fish, the steps of the present invention are further designed as follows:
before step S2 is executed, the fixing plate mounting groove is formed in the side wall of the water tank, so that the fixing plate is stably mounted, the influence factor on the displacement of the moving plate is smaller, the detection accuracy is higher, and the pressure control effect is better.
In step S3, the number of the ir receivers is at least one, and for more convenient receiving judgment, the ir receivers are arranged in a straight line, and of course, the ir emitters are arranged in a straight line.
Here, the infrared ray emitted by one infrared emitter can be received by a plurality of infrared receivers, and if the bending of the moving plate is convex bending, the infrared receiver at the back cannot receive the infrared ray emitted by the infrared emitter; otherwise if the movable plate is bent to be concave bending, the infrared receiver in the middle cannot receive the infrared ray sent by the infrared emitter, so that the bending detection of the movable plate is more accurate, and the pressure balance accuracy is higher.
Accordingly, when the infrared signal is not received by any of the infrared receivers, an alarm is issued in step S4. The absence of infrared signals from any of the infrared receivers indicates that the moving plate has been bent, i.e., a pressure imbalance.
It should be noted that, when step S1 is executed, the number of the connecting springs is at least three, and the length of the connecting springs is in a direct proportion. The displacement of the connecting springs under unit pressure is the same, so that the pressure applied to the moving plate during displacement is in direct proportion to the displacement.
In the case of changing one setting, when step S1 is executed, the number of the connecting springs is at least three, the lengths of the connecting springs are in a proportional relationship, and the connecting spring below is longer than the connecting spring above. And a longer displacement distance is ensured at a place with large water body pressure below the water body.
The water tank pressure control method suitable for freshwater fish is simple, practical, reasonable and effective, high in pressure balance measurement accuracy and capable of controlling various water tank pressures.
