Referring to fig. 1 to 4, the present embodiment provides a floating ball liquid level meter 1, which mainly includes: floating ball 11, sensing connecting rod 12, flange 13, signal converter 14 and anti-roll mechanism 15.
The anti-roll mechanism 15 comprises a connecting disc 151 and an anti-roll member. The connecting disc 151, the sensing connecting rod 12 and the flange plate 13 are coaxial, and the connecting disc 151 is welded on the lower side of the flange plate 13. The anti-roll member has a connection portion 152 and an anti-roll portion 153 fixedly connected, and the connection portion 152 and the anti-roll portion 153 are perpendicular to each other. The upper side of the connection portion 152 abuts on the lower side of the connection plate 151, and the anti-tilt portion 153 abuts on the upper portion of the sensing link 12. The connection portion 152 is detachably connected to the connection pad 151.
Before the floating ball liquid level meter 1 is installed at a preset position through the flange 13, the anti-tilting member can be connected to the connecting disc 151, at this time, the upper side of the connecting part 152 abuts against the lower side of the connecting disc 151, the anti-tilting part 153 abuts against the upper part of the sensing connecting rod 12, so that the inclination of the sensing connecting rod 12 is limited through the anti-tilting part 153, the sensing connecting rod 12 is kept vertical, and the accuracy of a detection result is ensured. In addition, since the connection part 152 is detachably connected to the connection disc 151, a user can reasonably select whether to install the anti-roll member according to his/her needs. For example, when the sensing link 12 has a short length, the sensing link 12 is not easily inclined by the impact of the water flow, and the anti-roll member can be detached from the connection plate 151.
In the present embodiment, the connection portion 152 and the anti-toppling portion 153 are each in the shape of a plate, and the anti-toppling member constituted by the connection portion 152 and the anti-toppling portion 153 is in the shape of an L, and at least two anti-toppling members are disposed along the circumferential direction of the sensing link 12 to restrict the inclination of the sensing link 12 from a plurality of directions.
In the present embodiment, the detachable connection of the connection portion 152 and the connection disc 151 is achieved by: the connection portion 152 is connected to the connection plate 151 by a first screw 161 and a first nut 162.
In order to ensure that the anti-roll portion 153 can abut against the sensing link 12, the connecting portion 152 is opened with a guide hole 163 matched with the first screw 161, and the diameter 1/2 of the first screw 161 is smaller than the length of the guide hole 163. The position of the connecting portion 152 is laterally adjustable to ensure that the anti-roll portion 153 can abut on the sensing link 12.
A side plate 171 is connected between the connection portion 152 and the anti-roll portion 153, and the side plate 171 can maintain the connection portion 152 and the anti-roll portion 153 in a perpendicular state.
In order to better maintain the connection portion 152 and the anti-roll portion 153 in a perpendicular state, there may be two side plates 171, and the two side plates 171 are parallel to each other.
In order to prevent the first screw 161 and the first nut 162 from rusting, sliding grooves 172 are formed in the two side plates 171, a sliding plate 173 is arranged between the two side plates 171, two sides of the sliding plate 173 are respectively inserted into one sliding groove 172, and the sliding plate 173 can slide along the sliding groove 172. The connecting portion 152 has a mounting notch 174 formed at a lower side thereof, a rotating shaft 175 is rotatably connected to the mounting notch 174, a torsion spring (not shown) and a push plate 176 are mounted on the rotating shaft 175, and when the push plate 176 rotates, the push plate 176 can push the sliding plate 173 toward the anti-roll portion 153. The push plate 176, the slide plate 173, the connection portion 152, the anti-roll portion 153, and the two side plates 171 can form an accommodation space for protecting the first screw 161 and the first nut 162 to prevent the first screw 161 and the first nut 162 from rusting. The side plate 171 may further be threadedly connected with a limiting rod 177, and the limiting rod 177 is used for limiting the rotation of the push plate 176.
As shown in fig. 4, before the first screw 161 and the first nut 162 are installed, the push plate 176 may be rotated clockwise, and then the limit rod 177 is rotated, so that one end of the limit rod 177 extends between the two side plates 171, and the limit rod 177 abuts against the lower side of the push plate 176, at this time, the rotation of the limit rod 177 in the counterclockwise direction is limited by the limit rod 177, and then the sliding plate 173 is pulled out from between the two side plates 171, at this time, the first screw 161 and the first nut 162 may be installed in place.
After the first screw 161 and the first nut 162 are installed in place, the sliding plate 173 is placed between the two side plates 171, and the limiting rod 177 is rotated in the reverse direction, so that the pushing plate 176 can rotate counterclockwise, and after the pushing plate 176 contacts the sliding plate 173, the pushing plate 176 can push the sliding plate 173 to the right, so that the right end of the sliding plate 173 abuts against the anti-tilting portion 153, and thus, an accommodating space for protecting the first screw 161 and the first nut 162 is formed by the pushing plate 176, the sliding plate 173, the connecting portion 152, the anti-tilting portion 153 and the two side plates 171, so as to prevent the first screw 161 and the first nut 162 from rusting.

In addition, because the connecting part 252 is detachably connected with the connecting disc 251, a user can reasonably select whether to install the anti-tilting member according to the requirement of the user. For example, when the sensing link 22 has a short length, the sensing link 22 is not easily inclined by the impact of the water current, and the anti-roll member can be detached from the connection plate 251.
In the present embodiment, the connecting portion 252 is annular, the anti-roll portion 253 is tubular, and both the connecting portion 252 and the anti-roll portion 253 are sleeved with the sensing link 22.
