Abstract
The utility model relates to the technical field of handset components and particularly relates to a high-sensitivity ultrasonic calorimeter. The high-sensitivity ultrasonic calorimeter comprises a meter body, reflection sheets, and energy transducers arranged in the meter body. Two sides of an inner wall of the meter body are axially provided with spacing grooves. The spacing grooves extend out of an outer end of the meter body. A support plate is plugged in each spacing groove and is provided with a connecting plate. Each connecting plate is formed by being directly punched by the support plate. Each support plate is corresponding to one energy transducer. Each support plate is provided with an installation groove for placing one reflection sheet. The high-sensitivity ultrasonic calorimeter is simple in structure; as the connecting plates are formed by being directly punched in an integrated body, the insulation grooves in the connecting plates can be precisely controlled; and angles of the installation grooves are formed through once punching. Thus, the working efficiency is greatly improved, installation is convenient, positions of the refection sheets can be precisely fixed, production efficiency and product quality can be improved.
Description
Technical field
The utility model relates to thermal energy consumption measuring apparatus field, relates in particular to a kind of highly sensitive ultrasonic calorimeter.
Background technology
Prior art discloses a kind of highly sensitive ultrasonic calorimeter, comprise table body, reflector plate and be arranged on the transducer in table body, described table body inwall is provided with sedimentation hole, and described sedimentation hole is corresponding with described transducer, and the support column for placing reflector plate is installed on sedimentation hole.Support column and sedimentation hole are tightened to one, because support column cross-sectional area is little, thus less to the obstruction of hot-fluid, the accuracy of guarantee flow measurement.This kind of structure found in practice is installed, the more difficult processing of sedimentation hole, process time is long, and when support column is arranged in sedimentation hole, reflector plate on support column is owing to being all manually support column to be riveted in sedimentation hole, cause the very difficult reflector plate aliging accurately on two support columns, deviation a bit a little, this highly sensitive ultrasonic calorimeter is just defective, cause in production the qualification rate of product lower, affect the quality of product, in addition, also exist and a kind of reflecting piece is arranged on to the calorimeter in back up pad, back up pad is inserted in table body, this structure is owing to being that one of directly welding is for placing the support column of reflector plate in back up pad, in the process of welding, the angle of support column is wayward, also can cause reflector plate to produce deviation, affect product quality.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of highly sensitive ultrasonic calorimeter is provided, and is convenient to install the position of two reflector plates that can align accurately.
The utility model for achieving the above object, by the following technical solutions: a kind of highly sensitive ultrasonic calorimeter, it is characterized in that: comprise table body, reflector plate and be arranged on the transducer in table body, described table body inwall is axially arranged with stopper slot on both sides, described stopper slot extends to the external end of table, in described stopper slot, be plugged with back up pad, described back up pad is provided with web joint, described web joint is directly stamped to form by described back up pad, described back up pad is corresponding with described transducer, and described back up pad is provided with the mounting groove for placing reflector plate; The two ends of described table body are provided with the nut of fastening described back up pad, and the inner side of described nut is provided with bar-shaped trough, and described bar-shaped trough is corresponding with described back up pad, and this back up pad can be inserted in described bar-shaped trough.
Preferably, described nut is stepped.
Preferably, described nut inner side is provided with sealing gasket.
The beneficial effects of the utility model are: the utility model is simple in structure, because web joint in this device is that direct integrated punching forms, so, mounting groove on web joint can accurately be controlled, the angle of mounting groove is also disposable impact briquetting, has greatly improved work efficiency, and it is convenient to install, the position of reflector plate can accurately be fixed, and has improved production efficiency and product quality.
Brief description of the drawings

Fig. 2 is side view of the present utility model;
In figure: 1, table body; 2, reflector plate; 3, transducer; 4, stopper slot; 5, back up pad; 6, back up pad; 7, mounting groove; 8, nut; 9, bar-shaped trough; 10, sealing gasket.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of highly sensitive ultrasonic calorimeter, comprise table body 1, reflector plate 2 and be arranged on the transducer 3 in table body, described table body inwall is axially arranged with stopper slot 4 on both sides, and described stopper slot extends to the external end of table, is plugged with back up pad 5 in described stopper slot, described back up pad is provided with web joint 6, described web joint is directly stamped to form by described back up pad, and described back up pad is corresponding with described transducer, and described back up pad is provided with the mounting groove 7 for placing reflector plate; In order back up pad to be fixed on to the inside of table body, be provided with the nut 8 of fastening described back up pad at the two ends of described table body, this nut is annular structure, the inner side of described nut is provided with bar-shaped trough 9, described bar-shaped trough is corresponding with described back up pad, bar-shaped trough and back up pad match, and the front end of back up pad can be inserted into this back up pad and can be inserted in described bar-shaped trough.In the utility model, in order to make this device more attractive in appearance, described nut is stepped.In order to make back up pad be connected closely with nut, do not produce displacement, described nut inner side is provided with sealing gasket 10, and sealing gasket plays the effect of buffering on the one hand, increases on the other hand the friction force between back up pad and nut.Described reflector plate is 45° angle and is arranged on support column, and the reflecting surface of two reflector plates is to correspondence, and the line of centres of reflecting surface is coaxial with pipe hole center line.Produce and launch ultrasound wave along water (flow) direction at the ultrasonic transducer of inlet segment setting, produce and launch ultrasound wave along the contrary direction of current at the ultrasonic transducer of water exit end setting, two ultrasonic transducers receive by reflector plate the ultrasonic signal that the other side launches mutually, and convert thereof into electric signal and deliver in integraph and process, according to ultrasound wave fluid flow in, the ultrasonic velocity of stream will be faster than the ultrasonic velocity flowing against the current downstream, calculate water velocity according to velocity contrast, water velocity is multiplied by sectional area and is multiplied by the flow that draws the table body of flowing through after correction factor again.
The utility model is simple in structure, because web joint in this device is that direct integrated punching forms, so, mounting groove on web joint can accurately be controlled, the angle of mounting groove is also disposable impact briquetting, has greatly improved work efficiency, and it is convenient to install, the position of reflector plate can accurately be fixed, and has improved production efficiency and product quality.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
