Description

Technical Field

[0001] The utility model relates to the technical field of meteorological and hydrological equipment, in particular to a large evaporation pan with automatic water addition and drainage. Background Technique

[0002] The E601 type evaporator is one of the instruments for measuring evaporation. Compared with small evaporators, due to the more reasonable and scientific instrument structure, installation height, surrounding environment, etc., the measured evaporation is more representative and closer to the evaporation situation of the natural water surface.

[0003] The existing E601 type evaporator includes an overflow bucket connected to the evaporation bucket, which is used to receive the part of water that overflows when the water level rises during rainfall, and this part of the water volume needs to be manually measured; and when the water level in the evaporation bucket drops to a certain height, relevant personnel need to manually add water, and at the same time, the water level height in the evaporation bucket needs to be kept appropriate after adding water, and the overall operation is rather cumbersome, consuming a large amount of manpower. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing E601 type evaporator needs manual water addition after the water level drops, and the part of the water volume overflowing due to precipitation needs to be manually measured, with cumbersome operation and waste of manpower; in view of the above problem, a large evaporation pan with automatic water addition and drainage is proposed, which includes an evaporation bucket and an overflow bucket. The overflow bucket is connected to an overflow port on the side wall of the evaporation bucket through an overflow pipe. A water addition port is also provided on the side wall of the evaporation bucket. One end of the water addition assembly is connected to the water addition port, and the other end of the water addition assembly is connected to the overflow bucket. An indication assembly for the water addition amount is arranged inside the evaporation bucket. The evaporation bucket is connected to an external water source through a water storage assembly. A metering assembly for measuring the overflow amount is arranged at the upper part of the evaporation bucket, and a water immersion sensor for determining the water storage amount in the overflow bucket is arranged at the bottom of the metering assembly.

[0005] According to the technical solution of the utility model, by setting the structure of the water addition assembly, when the water level drops to a certain height, water is automatically added into the evaporation bucket to ensure that the water level in the evaporation bucket always remains within an appropriate range; by setting the structure of the metering assembly, the overflow amount generated due to precipitation is directly measured to directly obtain the overflow amount, so as to obtain the evaporation amount subsequently; by setting the structure of the indication assembly, whether water needs to be added and when to stop adding water are determined through the relative positions of the floating ball with the lower wall and the upper wall, so that the water level in the evaporation bucket always remains within an appropriate range; the water storage assembly stores water at the lower part of the overflow bucket, can add water in time when water needs to be added, and makes the relevant data such as the temperature of the added water the same as the data of the existing water in the evaporation bucket. At the same time, when the overflow amount is too large and exceeds the upper limit of water storage, the water storage assembly can also discharge part of the stored water in time to prevent the metering assembly from being submerged and damaged.

[0006] For the optimization of the technical solution of the present utility model, the water filling port is located above the overflow port. When precipitation overflows, all the overflowed water will enter the overflow bucket through the overflow pipe, and will not partially enter the water filling port, resulting in inaccurate measurement of the overflow volume and thus affecting the calculation of the evaporation volume.

[0007] For the optimization of the technical solution of the present utility model, the water filling assembly includes a water filling pipe. One end of the water filling pipe is connected to the water filling port, and the other end extends into the bottom of the overflow bucket. A water pump is arranged on the water filling pipe, and the water pump is used to pump water into the evaporation bucket. The water filling pipe extends into the bottom of the overflow bucket, which is convenient for the water pump to pump water from the overflow bucket.

[0008] For the optimization of the technical solution of the present utility model, the water storage assembly includes a water storage pipe. One end of the water storage pipe is connected to an external water source, and the other end extends into the bottom of the overflow bucket. A two-way pump is arranged on the water storage pipe. When the water storage volume in the overflow bucket is higher than the upper limit, the two-way pump pumps out the water through the water storage pipe. When the water storage volume in the overflow bucket is too low, the two-way pump replenishes the water storage volume through the water storage pipe until it reaches the upper limit. The water storage volume in the overflow bucket always remains within a suitable range and will not affect the metering assembly above.

[0009] For the optimization of the technical solution of the present utility model, the indicating assembly includes a fixed rod. The fixed rod is connected to the outer wall of the evaporation bucket, and the other end extends into the interior of the evaporation bucket. The lower wall and the upper wall are connected by multiple connecting rods at the edge to form a cylindrical cavity. The top of the cylindrical cavity is connected to the fixed rod, and a floating ball is arranged in the cylindrical cavity. The position of the floating ball in the cylindrical cavity is used as the basis for determining whether the evaporation bucket needs to be filled with water.

[0010] For the optimization of the technical solution of the present utility model, pressure sensors are arranged on the opposite sides of the lower wall and the upper wall. When the water level drops and the floating ball fits against the lower wall, the pressure sensor transmits a signal indicating that water needs to be added. When the water level rises and the floating ball floats up and fits against the upper wall, the water addition stops.

[0011] For the optimization of the technical solution of the present utility model, the upper wall is located below the overflow port. After the water addition stops, the water level in the evaporation bucket is appropriate and will not cause overflow.

[0012] For the optimization of the technical solution of the present utility model, the metering assembly includes a funnel. The funnel is located below the overflow pipe, a partition is arranged below the funnel, a metering tipping bucket is arranged on the partition, and a water container above the metering tipping bucket is located directly below the funnel. Drainage openings are arranged on the partition. All the overflowed water is centrally collected through the funnel, then enters the metering tipping bucket through the water container, and the overflow volume can be obtained by the number of times the metering tipping bucket tips over.

[0013] For the optimization of the technical solution of the present utility model, two drainage openings are arranged, respectively on both sides of the metering tipping bucket. The metered water is discharged below the overflow bucket for water storage.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] According to the technical solution of the present utility model, by setting the structure of the water adding component, when the water level drops to a certain height, water is automatically added to the evaporation barrel to ensure that the water level in the evaporation barrel always remains within a suitable range; by setting the structure of the metering component, the overflow volume generated due to precipitation is directly measured to directly obtain the overflow volume, so as to obtain the evaporation volume subsequently; by setting the structure of the indicating component, whether water needs to be added and when to stop adding water are determined through the relative positions of the floating ball with the lower wall and the upper wall, so that the water level in the evaporation barrel always remains within a suitable range; the water storage component stores water at the lower part of the overflow barrel, can add water in time when water needs to be added, and makes the relevant data such as the temperature of the added water the same as the data of the existing water in the evaporation barrel. At the same time, when the overflow volume is too large and exceeds the upper limit of water storage, the water storage component can also discharge part of the stored water in time to prevent the metering component from being submerged and damaged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be described in detail with reference to the accompanying drawings in the embodiments of the present utility model Figures 1-6 of the present utility model. Example 1

[0024] As Figures 1-6 shown, the utility model is a large evaporating dish with automatic water addition and drainage, including an E601 type evaporator, which is a prior art and includes an evaporation barrel 1 and an overflow barrel 2. The overflow barrel 2 is connected to an overflow port 11 on the side wall of the evaporation barrel 1 through an overflow pipe 4.

[0025] As Figures 1-2 shown, in the utility model, a water filling port 12 is also opened on the side wall of the evaporation barrel 1. The water filling port 12 is higher than the overflow port 11. Therefore, when overflow occurs due to precipitation, all the overflowed water will enter the overflow barrel 2 from the overflow port 11, avoiding partial water remaining at the water filling port 12, resulting in inaccurate measurement of the overflow volume and further affecting the calculation of the evaporation volume.

[0026] The water filling assembly 3 includes a water filling pipe 32. One end of the water filling pipe 32 is connected to the water filling port 12, and the other end extends into the bottom of the overflow barrel 2. A water pump 31 is fixedly installed on the water filling pipe 32. The water pump 31 is placed on the ground. When water needs to be added, the water filling assembly 3 pumps water out from the bottom of the overflow barrel 2 through the water pump 31 and enters the evaporation barrel 1 through the water filling pipe 32.

[0027] As Figure 5 shown, the upper and lower limits of the water addition amount are determined by the indicating assembly 6. The indicating assembly 6 includes a fixing rod 61. The fixing rod 61 is fixedly connected to the outer wall of the evaporation barrel 1, and the other end extends over the evaporation barrel 1 and into its interior. The lower wall 62 and the upper wall 63 are circular plates and are fixedly connected by multiple connecting rods 64 around the edge to form a hollow cylindrical cavity. The cylindrical cavity is connected to the fixing rod 61. A floating ball is placed in the cylindrical cavity, and the floating ball can move up and down in the cylindrical cavity as the water level changes.

[0028] Pressure sensors are fixedly installed on the opposite sides of the lower wall 62 and the upper wall 63. The lower wall determines the lower water level of the evaporation barrel 1. When the water level drops below the lower wall 62 due to evaporation, the floating ball 65 fits against the lower wall 62, and the pressure sensor installed on its upper surface transmits a signal. The background terminal device receives the signal and makes a processing to control the water pump 31 to work and add water into the evaporation barrel 1. As the water level rises, the floating ball 65 gradually floats up and fits against the upper wall 63, and the pressure sensor on the lower surface of the upper wall 63 transmits a signal. The background terminal device receives the signal and makes a processing, and the water pump 31 stops working and the water addition stops, reaching the upper limit of the water addition amount.

[0029] The upper wall 63 is located below the overflow port 11. Therefore, when the water addition stops, the water level in the evaporation bucket 1 is lower than the overflow port 11, and no overflow occurs. Moreover, the above upper and lower limits only apply to the scenario when water needs to be added and do not represent the upper and lower limits of the water level in the evaporation bucket 1 itself. Additionally, the overall volume of the indicating component 6 is small and the cross-section is small, so the impact on the evaporation rate can be ignored.

[0030] As Figures 3-4 shown, the bottom of the overflow bucket 2 is a water storage cavity. The water in the water storage cavity has little difference in relevant data from the water in the evaporation bucket 1. Therefore, after the water in the water storage cavity is added to the evaporation bucket 1 through the water addition component 3, the difference is small and the impact on the evaporation rate is not significant. The water storage component 5 includes a water storage pipe 52. One end of the water storage pipe 52 is connected to an external water source, and the other end of the water storage pipe 52 extends into the bottom of the overflow bucket 2. A two-way pump 51 is installed on the water storage pipe 52.

[0031] Above the water storage cavity, a metering component 7 for measuring the overflow volume is provided. The metering component 7 adopts the principle of tipping bucket metering.

[0032] As Figure 6 shown, the metering component 7 includes a funnel 71. The funnel 71 is fixedly connected to the inner wall of the overflow bucket 2 and is located below the overflow pipe 4. A partition plate 72 is fixedly connected to the inner wall of the overflow bucket 2 and is arranged below the funnel 71. A metering tipping bucket 74 is installed on the upper surface of the partition plate 72. A water receiver 73 above the metering tipping bucket 74 is located directly below the funnel 71.

[0033] When an overflow occurs, the overflow water enters the overflow bucket 2 through the overflow pipe 4. The funnel 71 receives all the overflow water and makes it enter the water receiver 73, and then enters the bucket chamber on one side of the metering tipping bucket 74 from the water receiver 73. At this time, the bucket chamber on the other side is in a waiting state.

[0034] When the volume of the received water reaches a predetermined value, due to gravity, the metering tipping bucket 74 tips over. At this time, the other bucket chamber is in a working state and starts to receive water. When the received water volume reaches the predetermined value, it tips over again and is in a waiting state. Each time the metering tipping bucket 74 tips over, the magnet sweeps past the reed switch once, and the reed switch sends out a switch signal. The background terminal device receives the signal, and the overflow volume can be known through the number of tipping times.

[0035] Drainage openings are provided on the partition plate 72. It is advisable to set two drainage openings, respectively located on both sides of the metering tipping bucket 74. After the metering tipping bucket 74 tips over, the water in its bucket chamber enters the water storage cavity through the drainage openings.

[0036] The water immersion sensor 8 is installed at the bottom of the partition plate 72 of the metering component 7. The water immersion sensor 8 emits a signal when it comes into contact with water, which is used to judge the water storage volume in the water storage cavity. When the water storage volume in the water storage cavity reaches a certain amount, the liquid level contacts the water immersion sensor 8, and the water immersion sensor 8 transmits a signal. The background terminal device receives the signal and makes a processing. The two-way pump 51 works, and pumps out part of the water through the water storage pipe 52 to ensure that the water storage volume is kept within a suitable range. When the water storage volume is insufficient, at this time the background terminal device does not receive the signal of the water immersion sensor 8, and the two-way pump 51 adds water to the water storage cavity through the water storage pipe 52 until the liquid level contacts the water immersion sensor 8.

[0037] The process of adding water when the water storage volume is insufficient is only observed every day and is carried out after adding water to the evaporation bucket 1. At other times, the water storage component 5 will not add water to the water storage cavity. The water storage component 5 pumps water out due to overflow in real time, and will be carried out as long as the liquid level contacts the water immersion sensor 8, without time limit.

[0038] The evaporation amount of each specific day = the water surface height of the previous day + precipitation - the water surface height measured on the same day - the overflow amount. Among them, the precipitation is based on the observed value of the rain gauge, and the overflow amount is based on the observed value of the metering component 7. The electrical structure in this device is powered by the solar panel of the weather station, and there is no need to configure a separate functional structure.

[0039] The usage method of a large evaporation dish with automatic water addition and drainage in this embodiment is as follows:

[0040] During the daily observation, the liquid level height is obtained, and after calculating the evaporation amount of the same day, it enters the preparation stage of the next day. When the floating ball 65 of the indicating component 6 fits with the lower wall 62, at this time the pressure sensor on the lower wall 62 emits a signal, indicating that the water level in the evaporation bucket 1 is too low. The water pump 31 starts to work, and pumps out the water in the water storage cavity through the water addition pipe 32 and adds it into the evaporation bucket 1. The liquid level in the evaporation bucket 1 gradually rises, and the floating ball 65 rises accordingly and fits with the upper wall 63. The pressure sensor on the lower surface of the upper wall 63 emits a signal, and the water addition is completed. Since part of the water in the water storage cavity enters the evaporation bucket 1, the water level in the water storage cavity drops, and the water immersion sensor 8 is not in contact with the liquid level. At this time, the water storage component 5 starts to work, and pumps water from the water source into the water storage cavity through the two-way pump 52 until the liquid level contacts the water immersion sensor 8 and the water immersion sensor 8 emits a signal. The preparation stage work is completed, and the liquid level height at this time is measured through the measuring device of the E601 type evaporator, which is the actual water surface height today.

[0041] When overflow occurs due to precipitation, the amount of overflow water can be measured by the metering component 7. During this period, as the water level in the overflow bucket 2 increases and the liquid level submerges the water immersion sensor 8, the water immersion sensor 8 emits a signal, which is processed by the backend terminal device. The two-way pump 52 pumps out some water through the water storage pipe until the liquid level no longer touches the water immersion sensor 8. The evaporation amount of the next day = the actual water surface height after the preparation stage of the previous day + the precipitation amount - the water surface height at the time of the next day's observation - the overflow amount, where the precipitation amount is based on the observed value of the rain gauge and the overflow amount is based on the observed value of the metering component 7. The evaporation amount value can be directly obtained through calculation.

[0042] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
