Abstract

The utility model relates to a constant water level evaporation measuring device, particularly constant water level evaporation measuring equipment with an automatic water supplying device. The utility model is mainly composed of a transparent cylindrical water supply bucket of which the upper part and the lower part are sealed and a disk-shaped evaporating dish connected with the water supply bucket through a hose, and the side part of the bottom of the cylindrical water supply bucket is provided with a water outlet nozzle with a switch. The side part of the bottom of the disk-shaped evaporating dish is provided with a water inlet nozzle corresponding to the water outlet nozzle, and the hose (6) is connected between the water outlet nozzle and the water inlet nozzle. The outer wall of the cylindrical water supply bucket is provided with a graduated scale, and the top of the cylindrical water supply bucket is provided with a water injecting hole; the water injecting hole is sealed by a sealing plug with an air inlet pipe. The device can ensure the water level in the evaporating dish to keep a constant value and improve measurement precision.

Description

Position, a kind of water yield automatic supply Hengshui evaporation measurement mechanism

One, technical field

The utility model relates to position, a kind of Hengshui evaporation measurement mechanism, and especially a kind of water yield is position, the Hengshui evaporation measurement mechanism of supply automatically.

Two, background technology

Existing evaporation from water surface measurement mechanism, the change that the water level in its evaporating dish of one side does not stop in measuring process, liquid level variation certainly will cause evaporating the change of boundary condition, thereby influences its measuring accuracy; On the other hand, the observation water surface evaporation is the reduction of direct observed stage, and observational error is big, and precision is low.

Three, the content of utility model

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and water level keeps position, the water yield constant, that measuring accuracy is high automatic supply Hengshui evaporation measurement mechanism in a kind of evaporating dish and provide.

For achieving the above object, the utility model is achieved in that position, a kind of water yield automatic supply Hengshui evaporation measurement mechanism, its special character is, it mainly is by last, the transparent column shape water supply bucket of lower seal and the disc evaporating dish that links together by flexible pipe with it constitute, be provided with the faucet of belt switch in the cylindrical bottom side that supplies water bucket, the bottom side of disc evaporating dish is provided with and the corresponding water inlet tap of faucet, flexible pipe is connected between faucet and the water inlet tap, on the outer wall of the cylindrical bucket that supplies water, be provided with rule, top at the bucket that supplies water is provided with water injection hole, and water injection hole is sealed by a sealing-plug that has draft tube.

The utility model compared with the prior art, the automatic supply of timely and appropriate discovery when this device utilizes the water supply bucket that evaporating dish is carried out because of evaporating used up moisture, guaranteed that the water level of evaporating dish in evaporation process keeps constant, its evaporation capacity reads by the rule on the bucket that supplies water, error is little, observation degree of accuracy height, and it is simple in structure, with low cost, be particularly suitable for the measurement of open-air evaporation from water surface.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Five, embodiment

For understanding the utility model better, it is done detailed explanation below in conjunction with drawings and Examples.

As shown in Figure 1, position, the water yield described in the utility model automatic supply Hengshui evaporation measurement mechanism, position, a kind of water yield automatic supply Hengshui evaporation measurement mechanism, mainly be by on one, 1 and disc evaporating dish 2 that links together by flexible pipe 6 with it of the transparent column shape water supply bucket of lower seal constitutes, be provided with the faucet 5 of belt switch in the cylindrical bottom side that supplies water bucket 1, bottom side at disc evaporating dish 2 is provided with and faucet 5 corresponding water inlet taps 7, flexible pipe 6 is connected between faucet 5 and the water inlet tap 7, on the outer wall of the cylindrical bucket 1 that supplies water, be provided with rule 10, be used for reading the height of water supply inner bucket water face, the top of water supply bucket is provided with water injection hole, and water injection hole is sealed by a sealing-plug 3 that has draft tube 4.

Draft tube upper end owing to supply water in the bucket communicates with atmosphere, making the constant pressure at place, draft tube bottom is atmospheric pressure, by regulating the position of draft tube, the upper edge that makes its bottom and evaporating dish is on same surface level, can guarantee that water level in the evaporating dish remains with its coboundary flushes, thereby realizes the automatic water supplement function.

During measurement, the bucket that will supply water is placed on the support 8, evaporating dish is placed on the support 9, close the faucet switch of the bucket that supplies water, in bucket, inject a certain amount of water from water injection hole,, regulate the height of draft tube with sealing-plug jam-pack water injection hole, the upper edge that makes its bottom and evaporating dish is in same surface level, open the faucet switch, the water in the bucket that supplies water flow in the evaporating dish through connecting flexible pipe, and the water level in evaporating dish reaches the precalculated position, the level scale of record water supply this moment bucket, carry out water evaporates observation then, the level scale behind the record water supply bucket automatic water supplement, the difference of two level scales is evaporation capacity of moisture content, observation is directly perceived, the precision height.

Claims

1, position, a kind of water yield automatic supply Hengshui evaporation measurement mechanism, it is characterized in that: mainly be by last, the disc evaporating dish (2) that the transparent column shape of lower seal is supplied water barrel (1) and linked together by flexible pipe (6) with it constitutes, be provided with the faucet (5) of belt switch in the cylindrical bottom side that supplies water bucket (1), the bottom side of disc evaporating dish (2) is provided with and the corresponding water inlet tap of faucet (5) (7), flexible pipe (6) is connected between faucet (5) and the water inlet tap (7), on the outer wall of the cylindrical bucket (1) that supplies water, be provided with rule (10), its top is provided with water injection hole, and water injection hole is sealed by a sealing-plug (3) that has draft tube (4).
