Description

Novel sound velocimeter

The technical field is as follows:

the utility model relates to an engineering survey and drawing technical field especially relates to a novel sound velocimeter.

Background art:

the sound velocity meter is used for measuring the sound wave transmission speed in a medium, and the working principle of the sound velocity meter is that the speed of sound waves in the medium is calculated based on the measurement of the transmission time of the sound waves between two fixed points; the sound velocity meter among the prior art is including measuring the box, install the lead screw in the measurement box, install transmitting probe and receiving probe on the lead screw, the sound velocity meter of this kind of structure is used for detecting the propagation velocity of sound in liquid usually, also need all immerse the liquid medium with the measuring apparatu during use and detect, need multiunit data during owing to detect, the detection data that need change different positions and different distances gains the average value and just can guarantee higher detection, because the instrument is totally immersed inside liquid, many operations need go on in liquid, the operation is inconvenient, low work efficiency, treat further improvement urgently.

The utility model has the following contents:

an object of the utility model is to provide a novel sound velocity appearance.

The content of the utility model is as follows: a novel sound velocity meter comprises a measuring box body with an opening at the upper end, a lead screw is horizontally arranged in the measuring box body, two ends of the lead screw are rotatably connected with the inner wall of the measuring box body through bearings, two moving blocks are connected to the lead screw in a transmission manner, sliding blocks are fixedly connected to the bottom ends of the moving blocks, the sliding blocks are slidably connected with the bottom end of the measuring box body through guide rails, a transmitting probe is installed on one of the moving blocks, a receiving probe is installed on the other moving block, a turbine is concentrically installed on the lead screw and is meshed with a vertically arranged worm, the worm is concentrically installed on a rotating shaft, the bottom end of the rotating shaft is rotatably connected with a bottom plate of the measuring box body through bearings, and a plurality of water through holes are uniformly distributed on the bottom plate of the measuring box body, install the hand wheel after the crossbeam is passed on the top of rotation axis, the both ends of crossbeam and the inner wall fixed connection of square ring groove, square ring groove fixed mounting be in measure the inner wall of box a plurality of counter weight ring has been placed in the square ring groove install the installation handle in the inboard of counter weight ring seted up on the inner wall of square ring groove and placed the opening, the installation handle is located place in the opening.

Further, the measuring box body, the lead screw, the rotating shaft, the worm wheel and the worm are all made of plastics.

The utility model has the advantages that: the utility model discloses simple structure designs floating sound velocity measuring device, can finely tune measuring device's showy degree of depth according to the measurement demand, and adjusting hand wheel is located the liquid level more than completely simultaneously, needn't adjust in being surveyed liquid, adjusts convenient and fast, and maneuverability is strong, the effectual holistic detection efficiency that has improved.

Description of the drawings:

FIG. 1 is a perspective view of the internal structure of the present invention;

FIG. 2 is a front view of the present invention;

FIG. 3 is a perspective view of the counterweight ring of the present invention;

in the figure, a measuring box body 1, a lead screw 2, a moving block 3, a sliding block 4, a transmitting probe 5, a receiving probe 6, a turbine 7, a worm 8, a rotating shaft 9, a square ring groove 10, a hand wheel 11, a counterweight ring 12, a mounting handle 13 and a water through hole 14.

The specific implementation mode is as follows:

as shown in fig. 1 to 3, a novel sound velocimeter comprises a measuring box 1 with an open upper end, a lead screw 2 is horizontally arranged in the measuring box 1, both ends of the lead screw 2 are rotatably connected with the inner wall of the measuring box 1 through bearings, two moving blocks 3 are connected to the lead screw 2 in a transmission manner, a sliding block 4 is fixedly connected to the bottom ends of the moving blocks 3, the sliding block 4 is slidably connected to the bottom end of the measuring box 1 through a guide rail, a transmitting probe 5 is mounted on one of the moving blocks 3, a receiving probe 6 is mounted on the other moving block 3, a turbine 7 is concentrically mounted on the lead screw 2, the turbine 7 is engaged with a vertically arranged worm 8, the worm 8 is concentrically mounted on a rotating shaft 9, and the bottom end of the rotating shaft 9 is rotatably connected with the bottom plate of the measuring box 1 through a bearing, a plurality of water through holes 14 are uniformly distributed on a bottom plate of the measuring box body 1, a hand wheel 11 is mounted at the top end of the rotating shaft 9 after penetrating through a cross beam, two ends of the cross beam are fixedly connected with the inner wall of a square ring groove 10, the square ring groove 10 is fixedly mounted on the inner wall of the measuring box body 1, a plurality of counterweight rings 12 are placed in the square ring groove 10, a mounting handle 13 is mounted on the inner side of the counterweight rings 12, a placing opening is formed in the inner wall of the square ring groove 10, and the mounting handle 13 is located in the placing opening; the measuring box body 1, the lead screw 2, the rotating shaft 9, the turbine 7 and the worm 8 are all made of plastics.

The working principle is as follows: the during operation will the utility model discloses place the liquid level at the liquid that awaits measuring, measure box 1 this moment and be in the floating condition, then can place counterweight ring 12 in square ring groove 10 according to actual conditions, submerge transmitting probe 5 and receiving probe 6 position until the liquid level of the liquid that is surveyed, then measure can, measure the bearing and can adjust transmitting probe 5 and receiving probe 6's measurement interval through rotatory hand wheel 11, also can hand measurement box 1 make its shift position.
