Detailed Description

The invention will be further explained by means of the drawings and the specific embodiments

As shown in fig. 1-3, an auxiliary device of a hydrostatic level capable of reducing various errors comprises an upper shell 2, a clamping block 9 and a lower shell 12, wherein the clamping block is provided with a square mounting hole 8 for placing the hydrostatic level, the side wall of the square mounting hole is provided with an anti-slip cloth 7, the peripheral side wall of the clamping block is provided with a rivet hole I15, the peripheral side wall of the upper shell is provided with a rivet hole II 6, the upper shell and the lower shell are respectively provided with a mounting groove for penetrating through the clamping block, the clamping block is positioned in the mounting groove of the upper shell, and the clamping block and the upper shell are fixedly connected together by penetrating rivets in the rivet hole I and the rivet hole II; an upper shell bottom plate on the periphery of the installation groove is provided with a plug 14 protruding outwards, a lower shell top plate on the periphery of the installation groove is provided with a slot 11, and the upper shell and the lower shell are fixedly connected together by inserting the plug into the slot; go up and seted up cable mounting hole 3, trachea mounting hole 4 and water pipe mounting hole 5 on at least one lateral wall of casing, be connected with ball 10 that hangs down through four nylon ropes on the lower bottom surface of grip block, the one end of four nylon ropes is equallyd divide and is do not linked firmly on the lower bottom surface of grip block, the other end of four nylon ropes is all connected on the ball that hangs down.

In this embodiment, sliding connection has upper cover plate 1 on the mounting groove of upper housing roof, opens the upper cover plate, can conveniently observe inside hydrostatic level, closes the upper cover plate, can play dustproof effect.

In this embodiment, sliding connection has lower apron 16 on the mounting groove of casing bottom plate down, opens down the apron and is used for opening down the casing and use in order to maintain, look over internal arrangement, closes down the apron, can play dustproof effect.

In this embodiment, be close to the bottom plate and link firmly two fixed plates 13 that outwards protrude on the outer lateral wall of inferior valve body, seted up the rivet mounting hole on the fixed plate, through mounting rivet downwards in this rivet mounting hole, with the rivet nail ground, will descend the casing and link firmly together with ground.

The hydrostatic level is placed in the square mounting hole 8 of the clamping block.

In the embodiment, the plumb ball is a shot ball, and as shown in fig. 4, when the vibration occurs, the impulse with the magnitude Ft (instantaneous) is given to the whole structure by the outside, and at the moment, the impulse received by the hydrostatic level and the spherical damper connected with the hydrostatic level are equal. At this time, because the difference exists between the mass m1 of the control shot and the mass m2 of the level gauge, the instantaneous speed of the control shot and the mass m2 of the level gauge is different, compared with a static level gauge, the shot is hindered to move by four nylon ropes, and when the whole structure moves in the opposite direction, the blockage of the shot is more obvious. In addition, the shot improves the stability of the whole liquid level by reducing the gravity center position of the whole body, and the shot plays a role in two aspects; the effect of reducing the vibration of the liquid level is achieved.
