(54) УСТРОЙСТВО ДЛЯ СОЕДИНЕНИЯ ДАТЧИКА С ГЛАДКОЙ ПОВЕРХНОСТЬЮ(54) DEVICE FOR CONNECTING A SENSOR WITH A SMOOTH SURFACE

II

Изобретение относитс к приспособлени м , используемым дл обеспечени непосредственного контакта датчика с поверхностью среды, в которой регистрируютс какие-либо параметры, например при регистрации параметров упругих колебаний в подземной сейсморазведке дл жесткого соединени сейсмоприемника с поверхностью изучаемой среды.The invention relates to devices used to ensure direct contact of the sensor with the surface of the medium in which any parameters are recorded, for example, when recording parameters of elastic vibrations in underground seismic surveys for rigid connection of the seismic receiver with the surface of the studied medium.

Известно устройство дл соединени датчиков с гладкой поверхностью, содержащее камеру с присоской и подвижным дном св занным с т гами, выполненную в виде полого цилиндра, во внутреннюю полость которого помещен св занный с датчиком порщень , взаимодействующий через упругий элемент с толкателем имеющим хвостовик 1.A device for connecting sensors with a smooth surface is known, comprising a chamber with a suction cup and a movable bottom connected to the rods, made in the form of a hollow cylinder, in the internal cavity of which is placed a piston connected to the sensor, which interacts via a resilient element with a pusher having a shank 1.

Недостатком устройства вл ютс некачественные показани датчика.The drawback of the device is poor sensor readings.

Цель изобретени - повьпоение точности показаний датчика за счет повыщени надежности соединени .The purpose of the invention is to increase the accuracy of the sensor readings by increasing the reliability of the connection.

Цель достигаетс тем, что устройство дл соединени датчиков с гладкой поверхностью , содержащее камеру с присоской и подвижным дном с т гами, выполненнуюThe goal is achieved by the fact that a device for connecting sensors with a smooth surface, containing a chamber with a suction cup and a movable bottom with drafts,

В виде полого цилиндра, во внутреннюю полость которого помещен св занный с датчиком порщень взаимодействующий через упругий элемент с толкателем имеющим хвостовик, снабженны стойками, соединенными между собой осью, расположенными на наружной торцовой поверхности цилиндра , и кулачком щарнирно соединенным с т гами и установленным на упом нутой оси с возможностью контакта с хвостовиком толкател .In the form of a hollow cylinder, into the internal cavity of which is placed, connected to the sensor, a piston interacting through an elastic element with a pusher having a shank, equipped with struts interconnected by an axis located on the outer end surface of the cylinder, and with a cam pivotally connected to the rods and mounted on null axis with the possibility of contact with the shank of the pusher.

На фиг. 1 показано предлагаемое устройство; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows the proposed device; in fig. 2 is a view A of FIG. one.

Устройство содержит камеру 1 с присоской 2 выполненную в виде полого цилиндра , во внутренней полости 3 которого расположено подвижное дно 4 с т гами 5, The device contains a chamber 1 with a suction cup 2 made in the form of a hollow cylinder, in the inner cavity 3 of which there is a movable bottom 4 with t 5,

15 а в полости 6 расположены поршень 7, упругий элемент 8, толкатель 9 с хвостовиком и датчик 10. Наружна торцова поверхность 11 цилиндра снабжена стойками 12 и кулачком 13, щарнирно соединенным щтыр ми 14 с т гами 15 и установлен20 ным на оси 16 между стойками 12.15 and in the cavity 6 are located the piston 7, the elastic element 8, the pusher 9 with the shank and the sensor 10. The outer end surface 11 of the cylinder is equipped with struts 12 and a cam 13, pivotally connected with plugs 14 with thrusts 15 and mounted 20 on the axis 16 between the struts 12.

Claims

The operation of the device is as follows. In the initial state, the movable bottom 4 is located near the suction cup 2 of the chamber 1. The cam 13 is in the position when the rods 15 are lowered through the slots into the chamber. The pusher 9 is in the free polo 1 OLKZTSL x7 paLiA i l D - zhenin. The camera 1 is pressed to the surface of the studied medium by the suction cup and the lever is rotated to a fixed position shown in the figure. With this rotation, the movable bottom 4 of the cavity 3 is moved from the initial position to the position shown in the figure, thereby creating a discharge inside the chamber 1. As the force that presses the chamber 1 to the surface of the medium under study increases, the cam 13 slides along the pusher 9 and through the elastic element 8 increases the force acting on gun 7 with the sensor 10. The maximum value of this force corresponds to the cam position shown in the figure. The technical efficiency offered by the runesmanship of the device is that it allows reducing the influence of resonance effects on the quality of the materials produced. Tighter contact allows to increase the sensitivity of the recording channel by reducing losses in the area directly in contact with the seismic receiver. The installation time of the proposed object in comparison with the known one is shortened several times, since the installation is performed by a half turn of the cam, and not by repeated rotation of the stop nut, as is the case in the known device. Therefore, the proposed device is more economical in comparison with the known. It is assumed that it will be included in the comp. -, .. -, -, no lect of the stand of the mine seismic station under development. The invention The device for connecting a sensor with a smooth surface, containing a chamber with a suction cup and a movable bottom with rods, made in the form no.ic; o a cylinder, in the internal cavity of which is placed a piston associated with the sensor, which interacts through a resilient element with a pusher having A shank, characterized in that, in order to increase the accuracy of the sensor readings by increasing the reliability of the connection, it is provided with racks. ,, interconnected by an axle located on the outer face of the cylinder's verticality, and a cam pivotally connected to the rods and mounted on said axis with the possibility of contact with the shank of the pusher.
