Abstract
The utility model provides a simple and fast speed-measuring device. The simple and fast speed-measuring device comprises a liquid container, a speed-measuring head placed in the liquid container, a U-shaped speed-measuring tube connected with the lower end of the speed-measuring head, and a speed-measuring liquid arranged inside the U-shaped speed-measuring tube; the speed-measuring head includes an external measuring head and an internal measuring head arranged inside the external measuring head; and one end of the U-shaped speed-measuring tube is communicated with the internal measuring head, and the other end of the U-shaped speed-measuring tube is communicated with external measuring head. The simple and fast speed-measuring device of the utility model is advantageous in simple and convenient use, portable convenience, and fast and accurate speed measurement.
Description
Technical field
The utility model is specifically related to simple and direct, Quick Measuring speed variator.
Background technology
Speed measuring device is that the speed of flow liquid detects, ordinary surveying irrigation canals and ditches water velocity how, significant on irrigation canals and ditches construction and peasant kind of the ground that discharges water, travel outdoors and explore when paddling, also need the speed of probing current, not only cost compare is high for special-purpose velometer, and carry inconvenience, the efficient that tests the speed is slow, can not move reliably and with long-term, therefore can not satisfy the requirement that the rural area irrigation canals and ditches are built and tourism is explored.
Summary of the invention
Technical problem to be solved in the utility model is to provide simple and direct, Quick Measuring speed variator, not only easy to use, easy to carry, and also it is fast and accurately to test the speed.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: simple and direct, Quick Measuring speed variator, comprise liquid container, be placed on speed head in the liquid container, be connected to the speed head lower end the U-shaped pitot tube, be located at the liquid that tests the speed in the U-shaped pitot tube, described speed head comprises outer gauge head and is located at the interior interior gauge head of outer gauge head, described U-shaped pitot tube one end is communicated with interior gauge head, and the other end is communicated with outer gauge head.
As preferably, described speed head adopts the setting of inverted " L " type structure, described U-shaped pitot tube two ends are connected to the both sides of speed head, this structure speed head adopts the setting of inverted " L " type structure, U-shaped pitot tube two ends are connected to the both sides of speed head, structure is more reasonable, and is easily manufactured.
As preferably, described U-shaped pitot tube two ends and speed head junction are equipped with the protruding pipe of outside projection, this structure U-shaped pitot tube two ends and speed head junction are equipped with the protruding pipe of outside projection, and the current pressure that speed head is received has certain cushion effect, improve the standard that tests the speed.
As preferably, described speed head is towards opposite with liquid flow direction, this structure speed head is towards opposite with liquid flow direction, working fluid passes from the speed head end face, speed head is sensed the pressure of current, thereby transfer the pressure in the U-shaped pitot tube, make the liquid that tests the speed in the U-shaped pitot tube have certain water-head, finally measure the speed of current.
As preferably, described speed head head adopts the arcuate structure setting, and this structure speed head head adopts arcuate structure, has increased the contact area of speed head and liquid, has further improved the standard that tests the speed.
Beneficial effect:
The utility model adopts technique scheme that simple and direct, Quick Measuring speed variator is provided, and is not only easy to use, easy to carry, and it is fast and accurate to test the speed.
Description of drawings
Fig. 1 is structural perspective of the present utility model.
Embodiment
As shown in Figure 1, simple and direct, the Quick Measuring speed variator, comprise liquid container 1, be placed on the speed head 2 in the liquid container 1, be connected to the U-shaped pitot tube 3 of speed head 2 lower ends, be located at the liquid 4 that tests the speed in the U-shaped pitot tube 3, described speed head 2 comprises outer gauge head 21 and the interior gauge head 22 that is located in the outer gauge head 21, described U-shaped pitot tube 3 one ends are communicated with interior gauge head 22, the other end is communicated with outer gauge head 21, described speed head 2 adopts the setting of inverted " L " type structure, described U-shaped pitot tube 3 two ends are connected to the both sides of speed head 2, described U-shaped pitot tube 3 two ends and speed head 2 junctions are equipped with the protruding pipe 31 of outside projection, described speed head 2 is towards opposite with liquid flow direction, and described speed head 2 heads adopt the arcuate structure setting.
During real work, this structure speed head 2 adopts the setting of inverted " L " type structure, U-shaped pitot tube 3 two ends are connected to the both sides of speed head 2, structure is more reasonable, easily manufactured, this structure U-shaped pitot tube 3 two ends and speed head 2 junctions are equipped with the protruding pipe 31 of outside projection, the current pressure that speed head 2 is received has certain cushion effect, improve the standard that tests the speed, this structure speed head 2 is towards opposite with liquid flow direction, working fluid passes from speed head 2 end faces, speed head 2 is sensed the pressure of current, thereby transfers the pressure in the U-shaped pitot tube 3, makes the liquid 4 that tests the speed in the U-shaped pitot tube 3 have certain water-head, finally measure the speed of current, this structure speed head 2 heads adopt arcuate structure, have increased the contact area of speed head 2 with liquid, have further improved the standard that tests the speed, the utility model is not only easy to use, easy to carry, and it is fast and accurate to test the speed.
Specific embodiment described herein only is to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
