Description

Technical Field

[0001] The utility model relates to the technical field of dam displacement tension line monitoring, in particular to a tension line floating vessel water tank for operation and maintenance. Background Art

[0002] The tension line is generally set up in the observation corridor of the hydraulic dam, which is composed of an observation point, a survey line and a survey point box. The horizontal displacement of the observation point is measured by regularly measuring the distance between the observation point, the survey line and the baseline. The current survey point box is generally composed of a floating device and a CCD tension line meter. By placing a pontoon in the water tank and passing the tension line through the pontoon, the pontoon can lift the survey line to ensure the height position of the survey line and enable the survey line to move freely horizontally. When the survey line moves horizontally, the position of the survey line can be dynamically measured by the CCD tension line meter to obtain the required offset value.

[0003] The tension line pontoon is made of plastic and stainless steel. Due to the limitations of the process and the use environment, there are seams on the pontoon. Since it is relatively humid in spring and autumn, water will evaporate and enter the joints of the pontoon and liquefy into water in the cavity of the pontoon, causing the pontoon to become unstable, thus capsizing and sinking, and losing the lifting force for the survey line. On the other hand, the tension line is generally arranged in a trench and is outdoors (there are too many of them to be guarded around the clock). It is inevitable that it will be touched by small animals such as mice and geckos, causing the survey line to tilt sharply up and down for a certain period of time. If it is not discovered in time, when the water surface sinks into the joints of the pontoon and water flows into the cavity of the pontoon, the pontoon will also become unstable and capsize. Both of these situations will cause the tension line body to be unable to move freely, causing data collection anomalies. Often, in actual situations, in order to protect the tension-line instrument, the instrument is often stored in a sturdy protective box (a special key is required to open it), and an inspection often takes 1 to 2 minutes (it is necessary to remind yourself to wear the special key at all times). When encountering a hub project of 720 meters, with more than 20 tension-line instruments to be inspected on each floor, such inspections are time-consuming and laborious, and it is impossible to understand the true situation of the floating ship at all times and repair the abnormalities in time. At the same time, the floating ship loses stability and capsizes, and the tension-line instrument readings are abnormal, resulting in missing or abnormal data for the day, and the loss is immeasurable. It is particularly important to limit the immersion of the floating ship joints below the water surface. The draft of floating ships at different positions and their front and rear positions in the water tank are different, which also needs to be considered.

[0004] Therefore, a device is needed that can limit the immersion of the pontoon joint into the water surface and instantly determine whether the pontoon has capsized, so that the height position of the tensioning line can be kept in real time within the appropriate measurement height range of the CCD tensioning line instrument.

[0005] For this purpose, a tension line floating vessel water tank for operation and maintenance is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problems raised in the above background technology, and the utility model provides a tension line floating vessel water tank for operation and maintenance.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A tension line floating water tank for operation and maintenance, comprising a protection box body, a protection box cover hingedly installed on the top surface of the protection box body, a water tank assembly is provided at the inner bottom of the protection box body, a side wall of the water tank assembly is provided with a magnetic handle, and a side wall of the water tank assembly is provided with a limiting rod through the magnetic handle, a pontoon is provided inside the water tank assembly, a pontoon seam is provided on the surface of the pontoon, and tension lines are inserted into the left and right side walls of the protection box body, and the tension lines are connected to the top surface of the pontoon.

[0009] Furthermore, the water tank assembly includes a water tank body, the water tank body is fixedly installed on the inner bottom of the protection box body, the left and right side walls of the water tank body are both provided with grooves, and thin walls are fixedly installed inside the grooves.

[0010] Furthermore, the magnetic handle includes a rubber block, and the left and right side walls of the thin wall on the left are both fitted with rubber blocks, and the opposite surfaces of the two groups of rubber blocks are provided with installation cavities, and magnets are inserted into the interior of the installation cavities.

[0011] Furthermore, the thin wall is made of high-definition transparent glass material.

[0012] Further, in the initial state, the limiting rod is located below the bottom of the floating boat, and the limiting rod is not in contact with the bottom of the floating boat.

[0013] Furthermore, the rubber blocks are made of rubber material, and the magnets on the surfaces of the two groups of rubber blocks are arranged correspondingly.

[0014] The beneficial effects of the utility model are as follows:

[0015] When in use, open the protective box cover on the top of the protective box body, first drain water into the water tank assembly to a suitable water level, set up the position of the pontoon and the tension line, let it stand for a few minutes, and after the position of the pontoon is stable, press down one side of the pontoon until the pontoon joint is close to the water surface of the water tank, put the limit rod into the water tank, pull out the sleeve of the limit rod, move the limit rod to a height that makes one end of the limit rod contact the front end of the bottom of the pontoon, and then use the suction force of the magnetic handle on the surface of the water tank assembly to fix the limit rod, and use the same method to fix another pontoon to complete the installation. Function: Under short-term accidental disturbance, the pontoon will not take in water. After the disturbance is removed, the pontoon will automatically recover. When leaving the pontoon, the pontoon can move and retract automatically, and can be adjusted to a longer distance from the bottom of the pontoon to prevent the restriction of the free movement of the pontoon by the limiting rod under normal circumstances, so as not to affect the reading. During daily inspections, inspectors can press one side of the pontoon by hand when passing by the device to observe whether there is still room for downward rotation. If not, it indicates that there is liquefied water vapor in the pontoon cavity, which needs to be removed and the distilled water removed. BRIEF DESCRIPTION OF THE DRAWINGS
