Description

Technical Field

[0001] The present application belongs to the technical field of ground meteorological observation, and in particular relates to an evaporator with an automatic water adding system. Background Art

[0002] Ground-based meteorological observation refers to the methods and techniques of measuring and observing meteorological elements and weather phenomena using instruments and visual observation on various ground observation platforms; among them, evaporation observation performed by evaporators is an important part of ground-based meteorological observation and an important way to achieve water vapor exchange between the ground and the air.

[0003] The evaporator in the prior art is usually observed by measuring the evaporation amount of the liquid surface. Specifically, due to the evaporation phenomenon, the depth of the water layer in the evaporator container is constantly changing; by recording the liquid level within a certain time interval, the corresponding evaporation amount can be obtained. Among them, after the water layer drops, the inner wall of the evaporator container will block part of the liquid surface, so the evaporation amount in the next time interval will be reduced accordingly, resulting in inaccurate evaporation measurement results.

[0004] In order to solve this problem, in the prior art, water is added to the container again after each recording of the evaporation amount to ensure that the initial liquid level height is consistent in each time interval; wherein, adding water to the evaporator container is mainly achieved through manual operation, specifically, manually injecting water into the container, and observing the corresponding liquid level sensor value at the same time to ensure that the final liquid level height meets the requirements.

[0005] The inventors have found that when the time interval between each evaporation measurement is short and the number of measurements is large, manually adding water consumes a lot of manpower and has technical defects such as low efficiency and large error in the amount of water added.

DETAILED DESCRIPTION

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] Please also read Figures 1 to 6 The evaporator with automatic water adding system provided by the present application is now described. The evaporator with automatic water adding system provided by the present application comprises an evaporator container 1, a water replenishing container 2, a water storage container 4, a two-way pump 5, a heater 511 and a controller 7.

[0051] The evaporator container 1 is used to store liquid; in actual use, the evaporation amount in the corresponding time period is recorded by observing the amount of liquid inside the evaporator container 1. In this embodiment, the evaporator container 1 is connected to a first water level monitor 11 for monitoring the internal water level height, a water temperature monitor 12 for monitoring the internal liquid temperature, and a water inlet pipe 13 connected to the inside.

[0052] The water replenishment container 2 is arranged in parallel with the evaporator container 1, and is also used to store liquid. Its structure is the same as that of the evaporator container 1. The technical purpose of designing the above structure is that the temperature of the liquid in the water replenishment container 2 is similar to that of the evaporator container 1. In this embodiment, a water collector 3 is arranged on the water replenishment container 2, and the water collector 3 is used to collect the liquid at the liquid surface in the water replenishment container 2.

[0053] The water storage container 4 is used to contain liquid and has a water outlet pipe 41 connected to the interior thereof; it should be noted that the temperature of the liquid contained in the water storage container 4 is much lower than the temperature of the liquid in the evaporator container 1 and the water replenishment container 2 .

[0054] The bidirectional pump 5 is used to provide kinetic energy for the transportation of liquid. According to the direction of liquid transportation, the bidirectional pump 5 has a forward transportation state and a reverse transportation state. Specifically, the bidirectional pump 5 has a first water pipe 51 and a second water pipe 52. The first water pipe 51 is connected to the water extractor 3. The second water pipe 52 is connected to the water inlet pipe 13 and the water outlet pipe 41 through the three-way valve 6.

[0055] In actual use, by adjusting the three-way valve 6 , the second water pipe 52 can be connected to the water inlet pipe 13 , or the second water pipe 52 can be connected to the water outlet pipe 41 .

[0056] When the second water pipe 52 is connected to the water inlet pipe 13 and the two-way pump 5 is in the forward conveying state, the liquid inside the water replenishment container 2 can enter the evaporator container 1 through the water extractor 3, the first water pipe 51, the two-way pump 5, the second water pipe 52, and the water inlet pipe 13 in sequence, thereby realizing the water adding operation on the evaporator container 1.

[0057] When the second water pipe 52 is connected to the water outlet pipe 41 and the two-way pump 5 is in the reverse conveying state, the liquid inside the water storage container 4 can enter the water replenishment container 2 through the water outlet pipe 41, the second water pipe 52, the two-way pump 5, the first water pipe 51, and the water extractor 3 in sequence, thereby realizing the water adding operation to the water replenishment container 2.

[0058] The heater 511 is arranged on the first water pipe 51, and is used to heat the liquid in the first water pipe 51 to ensure the temperature of the liquid input into the evaporator container 1 from the water replenishment container 2 and the liquid input into the water replenishment container 2 from the water storage container 4, thereby ensuring the stability of the system when in use.

[0059] It should be noted that the heater 511 is disposed on the first water pipe 51 because this can reduce the required length of the second water pipe 52 , thereby reducing the error caused by residual liquid inside the second water pipe 52 .

[0060] The controller 7 is electrically connected to the signal output module of the first water level monitor 11, the signal output module of the water temperature monitor 12, the control module of the two-way pump 5, the control module of the three-way valve 6, and the control module of the heater 511; in actual use, the controller 7 can adjust the three-way valve 6 to connect the second water pipe 52 and the water inlet pipe 13, or the second water pipe 52 and the water outlet pipe 41; at the same time, the controller 7 can also start the two-way pump 5 to the forward conveying state or the reverse conveying state.

[0061] Moreover, the controller 7 can preset a first value; when the output value of the first water level monitor 11 is equal to or greater than the first value, the controller 7 can control the bidirectional pump 5 to stop, thereby ensuring the total amount of liquid delivered to the evaporator container 1 through the water replenishment container 2.

[0062] At the same time, the controller 7 can also start the heater 511 in time, and adjust the heater 511 according to the value of the water temperature monitor 12, so that the liquid temperature input to the evaporator container 1 is the same as the liquid temperature inside the evaporator container 1, and the liquid temperature input to the water replenishment container 2 is the same as the liquid temperature inside the evaporator container 1.

[0063] In the embodiment of the present application, the first water level monitor 11 can be used to monitor the liquid level inside the evaporator container 1 in real time to obtain the liquid evaporation amount in the corresponding time period; after each recording of the evaporation amount, the three-way valve 6 can be adjusted and the two-way pump 5 can be started through the controller 7 to allow the liquid in the water replenishment container 2 to be input into the evaporator container 1; at the same time, by comparing the first value with the output value of the first water level monitor 11 through the controller 7, the stop timing of the two-way pump 5 can be controlled, thereby controlling the amount of water added to the evaporator container 1, so that the measurement results of each round of liquid evaporation amount are more accurate.

[0064] Among them, the controller 7 can control the heater 511 to start, and make the heating temperature of the heater 511 the same as the liquid temperature inside the evaporator, so that the temperature of the liquid entering the evaporator container 1 is consistent with the temperature of the liquid originally in the evaporator container 1, avoiding large temperature changes in the evaporator container 1 each time water is added; at the same time, since the evaporator container 1 and the water replenishment container 2 are in the same environment, the temperatures of the liquids in the two are similar, so the power of the heater 511 will not be too large and the water delivery distance does not need to be too long, which plays a role in optimizing the system.

[0065] After the evaporator container 1 is filled with water for multiple times, the three-way valve 6 can be adjusted and the two-way pump 5 can be started through the controller 7 so that the liquid in the water storage container 4 is input into the water replenishment container 2, thereby ensuring the stability of the system operation.

[0066] Compared with the prior art, the evaporator with an automatic water adding system provided in this embodiment can replace the original manual water adding with automatic water adding, thereby saving manpower while ensuring the water adding efficiency and reducing the error of the water adding amount.

[0069] The control module of the signal generator 71 and the signal output module of the second water level monitor 21 are both electrically connected to the controller 7, and the controller 7 can also preset the second value.

[0070] By adopting the above technical solution, when the output value of the second water level monitor 21 is less than the second value, the controller 7 can control the signal generator 71 to start, so as to remind the operator to add water in time.
