Description

Technical Field

[0001] The utility model relates to the technical field of experimental water storage, in particular to an intelligent water storage tank for experiments. Background Art

[0002] Because the water flow rate required for the rapid cooling spray gun atomization experiment is much greater than the general tap water replenishment, in order for the experiment to proceed smoothly, we must add a large-capacity water storage tank that can meet the experimental water needs. However, general water storage tanks often have low liquid levels due to untimely replenishment, and the experiment is forced to be interrupted. Severe cases may even damage the water pump and cause certain economic losses. General water storage tanks may also forget to turn off the manual water replenishment valve after replenishing water, causing water overflow, resulting in waste of water resources and even water damage to laboratory equipment, leading to huge economic losses. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an intelligent water storage tank for experiments to solve the above problems.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] An intelligent water storage tank for experiment comprises a water storage tank, a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are respectively installed at the top and the bottom of the water storage tank, the water outlet pipe is provided with a water outlet valve and an experimental water pump, the water inlet pipe is provided with an electric valve, and one end of the water inlet pipe extends to the bottom end of the water storage tank, an ultrasonic level meter is provided at the top of the water storage tank at a distance of 1 / 3 of the diameter from the tank wall, an electrical control cabinet is provided outside the water storage tank, a liquid level controller, a liquid level high and low alarm lamp and a buzzer are arranged in the electrical control cabinet, a valve closing liquid level, a valve opening liquid level, an alarm liquid level and a pump stopping liquid level are sequentially set from top to bottom on the water storage tank through the liquid level controller, and the electric valve and the ultrasonic level meter are electrically connected to the electrical control cabinet.

[0006] In the above utility model, further, a return pipe and a pressure sensor are connected to the downstream end of the experimental water pump, and one end of the return pipe extends to the bottom end of the water storage tank.

[0007] In the above utility model, further, a maintenance manhole and an exhaust port are provided on the top of the water storage tank.

[0008] In the above utility model, further, the top end and the bottom end of the water storage tank are respectively provided with an overflow port and a drain port.

[0009] In the above utility model, further, a filter is provided at the upstream end of the experimental water pump.

[0010] The beneficial effects of the utility model are:

[0011] The ultrasonic level meter is used to monitor in real time the valve closing level, valve opening level, alarm level and pump stop level set by the level controller. When the ultrasonic level meter detects that the liquid level in the water storage tank has reached the above-mentioned level, the electric valve is opened and closed in time according to the control circuit in the electrical control cabinet, or an alarm is sounded to the experimenter through the buzzer, warning the experimenter that the experiment needs to be suspended as soon as possible due to insufficient water replenishment and wait for the liquid level to be replenished before restarting the experiment. The experimenter can decide whether to continue the experiment according to the actual situation to avoid damage to the experimental water pump due to idling due to insufficient water; secondly, one end of the water inlet pipe extends to the bottom of the water storage tank and the ultrasonic level meter is set at the top of the water storage tank at 1 / 3 of the diameter of the tank wall to prevent the surface water waves from swaying when water or quenching liquid is added to the storage tank, which affects the accurate monitoring of the ultrasonic level meter and causes the electrical control cabinet to make wrong instructions.

DETAILED DESCRIPTION

[0014] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0015] Please see attached Figure 1As shown, an experimental intelligent water storage tank 1 includes a water storage tank 1, a water inlet pipe 2 and a water outlet pipe 7, wherein the water inlet pipe 2 and the water outlet pipe 7 are respectively installed at the top and the bottom of the water storage tank 1, and the water outlet pipe 7 is provided with a water outlet valve 9 and an experimental water pump 8, and the water inlet pipe 2 is provided with an electric valve 3, and the electric valve 3 is used to control the water inlet pipe 2 to replenish water into the water storage tank 1, and an ultrasonic level meter 4 is provided at the top of the water storage tank 1 at a distance of 1 / 3 of the diameter of the tank wall, because the induction probe of the ultrasonic level meter 4 detects downward at a certain radiation angle, if the ultrasonic level meter 4 is set on the tank wall, the tank wall will produce a certain echo beam interference to it, and if the ultrasonic level meter 4 is placed in the middle of the top, when it is necessary to put a quenching material into the water storage tank 1, it will also interfere with the detection of the ultrasonic level meter 4, therefore, setting the ultrasonic level meter 4 at the top of the water storage tank 1 at a distance of 1 / 3 of the diameter of the tank wall is the best solution;

[0016] An electrical control cabinet 13 is provided outside the water storage tank 1, and a liquid level controller, a liquid level high and low alarm lamp, and a buzzer (none of which are marked in the attached drawings) are provided inside the electrical control cabinet 13. The valve closing liquid level, valve opening liquid level, alarm liquid level, and pump stopping liquid level are sequentially set from top to bottom on the water storage tank 1 through the liquid level controller. The liquid level can be controlled and the tank liquid level height can be displayed through various data manually input by the liquid level controller. Among them, the electric valve 3 and the ultrasonic liquid level meter 4 are both electrically connected to the electrical control cabinet 13, and the electric valve 3 is opened and closed through the control circuit of the electrical control cabinet 13, thereby realizing that the water inlet pipe 2 replenishes or stops replenishing water to the water storage tank 1;

[0017] Preferably, when the water inlet pipe 2 replenishes water to the water storage tank 1, in order to prevent the quenching liquid or tap water from falling into the water storage tank 1 from a high place and causing the liquid level in the water storage tank 1 to shake, thereby affecting the ultrasonic level meter 4 to detect the liquid level, causing the electrical control cabinet 13 to shut off the water inlet in advance or alarm in advance, one end of the water inlet pipe 2 is extended to the bottom end of the water storage tank 1.

[0018] In the above embodiment, preferably, the downstream end of the experimental water pump 8 is connected with a return pipe 11 and a pressure sensor 12. The pressure sensor 12 is used to detect the pressure in the water outlet pipe 7. If a high pressure is detected, the switch valve on the return pipe 11 is opened, so that part of the water flows back to the water storage tank 1 through the return pipe 11, thereby adjusting the pressure in the return pipe 11. Similarly, one end of the return pipe 11 extends to the bottom end of the water storage tank 1, which has the same principle as the inlet pipe 2.

[0019] The top of the water storage tank 1 is also provided with a maintenance manhole 5 and an exhaust port 6. The maintenance manhole 5 is used for equipment maintenance, and the exhaust port 6 is used to balance the pressure difference between the inside and outside of the storage tank.

[0020] The top and bottom ends of the water storage tank 1 are respectively provided with an overflow port 14 and a drain port 15 . When the inside of the water storage tank 1 needs to be cleaned or repaired, the liquid inside the water storage tank 1 is drained from the drain port 15 .

[0021] Because the present structure is used for atomization by a spray gun, particulate matter may exist in the tap water or the quenching liquid, causing damage to the water pump or the spray gun. Therefore, a filter 10 is provided at the upstream end of the experimental water pump.

[0022] During specific use, the four liquid level values ​​of the valve closing level, valve opening level, alarm level and pump stop level are manually set through the electrical control cabinet 13. When the ultrasonic level meter 4 detects that the liquid level is lower than the valve opening level, a signal is sent to the liquid level controller in the electric control cabinet, and the liquid level controller outputs a relay signal to control the intermediate relay to close, thereby controlling the electric valve 3 to open and replenish water in the water storage tank 1; when the ultrasonic level meter 4 detects that the internal liquid level reaches the valve closing level, the intermediate relay is disconnected through the liquid level controller to close the electric valve 3 and stop water intake, thereby stabilizing the internal liquid level of the liquid storage tank at an ideal height;

[0023] When the experiment time is too long, the water consumption of the experiment is greater than the tap water replenishment, so the liquid level of the water tank 1 will gradually become lower. When the liquid level is detected to be lower than the alarm level, the liquid level controller outputs a relay signal to close the relay of the alarm level, and controls the low liquid level alarm signal light to flash and the buzzer to sound an alarm through the relay, warning the experimenter that the experiment needs to be suspended as soon as possible due to insufficient water replenishment and wait for the liquid level to be replenished before re-experimenting; when the liquid level drops to the stop pump level, the liquid level controller outputs a relay signal to control the middle relay of the stop pump level to close, and the relay forcibly terminates the experiment by cutting off the experimental water pump 8 circuit to avoid damage to the experimental water pump 8 due to idling due to insufficient water. When the liquid level rises above the stop pump level and below the alarm level, the water pump can start normally, but the liquid level alarm light and buzzer still alarm. When the liquid level rises above the alarm level, the liquid level controller disconnects the low liquid level alarm middle relay to stop the alarm output, and the experimenter can decide whether to continue the experiment according to the actual situation.

[0024] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
