Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, in particular to a water level benchmark. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. Water is a precious resource indispensable to human production and life. A water conservancy project requires the construction of different types of hydraulic structures such as dams, sluices, water inlets, fishways, etc. In water conservancy projects, it is often necessary to use a water level rod to test the depth of the water. The water level rod reads the data through a float. The current water level rod is difficult to position the float, which makes it easy for the float to fall off during transportation. In addition, when adjusting the length of the water level rod, the float may be damaged, thereby reducing the applicability of the water level rod. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a water level marker, which solves the problem that the current water level marker is difficult to play a certain positioning role on the floating block, resulting in the floating block easily falling off during the transportation of the positioning marker, and the floating block is easily damaged when the length of the water level marker is adjusted.

[0004] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a water level marker, comprising a telescopic marker, a cover plate connected to the telescopic marker, a floating block overlapped under the cover plate, the floating block sleeved outside the telescopic marker, a scale line opened outside the telescopic marker, a card plate provided on the cover plate, an adjustment structure connected to the cover plate, the card plate connected to the adjustment structure, a slot opened outside the floating block, an auxiliary block connected in the slot, the card plate and the slot snapped together, the adjustment structure comprising a rotating plate, a positioning rod connected in the rotating plate, the positioning rod rotatably connected in the cover plate, a torsion spring externally connected to the positioning rod, the rotating plate is connected to the cover plate via the torsion spring, a rotating knob provided on the positioning rod, a fixing rod connected to the rotating plate, and the fixing rod connected to the fixing plate via the connecting plate.

[0005] As a further solution of the utility model: a base is connected under the telescopic pole, and a plug-in is connected inside the base.

[0006] As a further solution of the utility model: a groove is formed outside the telescopic pole, and the auxiliary block is slidably connected in the groove.

[0007] As a further solution of the utility model: a roller is arranged inside the auxiliary block, and the roller is overlapped outside the telescopic pole.

[0008] As a further solution of the utility model: a slide groove is provided on the cover plate, a slider is slidably connected in the slide groove, and the slider is connected under the clamping plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The water level mark is provided with a card plate, a card slot and an adjustment structure. After the positioning rod is rotated by the turning knob, the card plate will move to both sides with the rotation of the turning plate, and the torsion spring will be deformed when the turning plate rotates, and the floating block will be moved to overlap with the cover plate. When the turning knob is released, the turning plate will automatically reset through the action of the torsion spring, and the connecting plate will pull the card plate and the card slot for clamping. The water level mark can play a certain positioning role on the floating block after the card plate and the card slot are clamped through the cooperation between the turning plate, the torsion spring and the connecting plate, thereby avoiding the phenomenon that the floating block of the positioning mark falls off during transportation, preventing the possibility of the floating block being damaged when the length of the water level mark is adjusted, and effectively ensuring the applicability of the water level mark.

[0011] 2. The water level benchmark is provided with grooves, auxiliary blocks and rollers. When the river depth is detected, the rollers in the auxiliary blocks will roll on the surface of the telescopic benchmark, and the auxiliary blocks will also slide in the grooves, so that the floating block is not easily displaced during the descent process, thereby preventing the floating block from getting stuck when sliding on the surface of the telescopic benchmark.

[0012] 3. The water level benchmark is provided with a slide groove. When the pallet is subjected to thrust or tension, the slider below will slide in the slide groove, so that the slide groove plays a certain guiding role for the pallet, avoiding the phenomenon of dislocation of the pallet when it moves.

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-4 The utility model provides a technical solution: a water level benchmark, including a telescopic benchmark 1, a cover plate 2 is connected to the telescopic benchmark 1, a base 7 is connected to the telescopic benchmark 1, a plug-in 8 is connected to the base 7, a floating block 3 is overlapped under the cover plate 2, the floating block 3 is sleeved on the outside of the telescopic benchmark 1, and a scale line 9 is opened on the outside of the telescopic benchmark 1, a card plate 4 is provided on the cover plate 2, an adjustment structure 6 is connected to the cover plate 2, the card plate 4 is connected to the adjustment structure 6, a card slot 5 is opened on the outside of the floating block 3, and a card slot 5 is connected to the inside of the card slot 5. Auxiliary block 11, a groove 10 is opened outside the telescopic pole 1, the auxiliary block 11 is slidably connected in the groove 10, a roller 12 is arranged inside the auxiliary block 11, and the roller 12 is overlapped outside the telescopic pole 1. By setting the groove 10, the auxiliary block 11 and the roller 12, when the river depth is detected, the roller 12 will roll on the surface of the telescopic pole 1, so that the position of the floating block 3 is not easy to be offset during the descent process, and the floating block 3 is prevented from getting stuck when sliding on the surface of the telescopic pole 1;

[0020] The card plate 4 is connected with the card slot 5, and a slide slot 13 is provided on the cover plate 2. A slider 14 is slidably connected in the slide slot 13. The slider 14 is connected under the card plate 4. By setting the slide slot 13, when the card plate 4 is subjected to a thrust or a pull, the slider 14 below will slide in the slide slot 13, so that the slide slot 13 plays a certain guiding role for the card plate 4, thereby avoiding the phenomenon of dislocation of the card plate 4 when it moves;

[0021] The adjustment structure 6 includes a rotating plate 601, a positioning rod 603 is connected inside the rotating plate 601, the positioning rod 603 is rotatably connected inside the cover plate 2, and a torsion spring 604 is connected to the outer sleeve of the positioning rod 603. By setting the positioning rod 603, when the positioning rod 603 is driven to rotate by the knob 602, the rotating plate 601 will rotate with the rotation of the positioning rod 603, so that the positioning rod 603 plays a certain limiting role on the rotating plate 601, thereby preventing the rotating plate 601 from falling off when rotating;

[0022] The rotating plate 601 is connected to the cover plate 2 through a torsion spring 604, a rotating button 602 is provided on the positioning rod 603, a fixing rod 605 is connected to the rotating plate 601, and the fixing rod 605 is connected to the card plate 4 through a connecting plate 606. By setting the connecting plate 606, when the rotating plate 601 rotates, the card plate 4 can be pulled to move through the connecting plate 606, so that the connecting plate 606 plays a certain supporting role for the card plate 4, thereby avoiding the collision of the card plate 4 when moving.

[0023] The working principle of the utility model is:

[0024] When the length of the telescopic pole 1 is adjusted, the positioning rod 603 can be rotated by the knob 602, and the rotating plate 601 will also rotate accordingly. Since the rotating plate 601 is connected to the clamping plate 4 through the connecting plate 606, the clamping plate 4 will move to both sides as the rotating plate 601 rotates, and the torsion spring 604 will deform when the rotating plate 601 rotates, and move the floating block 3 to overlap with the cover plate 2. When the knob 602 is released, the rotating plate 601 will automatically reset due to the action of the torsion spring 604, and the connecting plate 606 will pull the clamping plate 4 to clamp with the clamping slot 5, so that the floating block 3 can be fixed under the clamping slot 5.

[0025] When the card plate 4 is subjected to thrust or tension, the slider 14 below will slide in the slide groove 13, and after the telescopic benchmark 1 is fixed to the measured river through the base 7 and the plug-in 8 below, the floating block 3 will be released. After the floating block 3 is affected by gravity, the roller 12 in the auxiliary block 11 will roll on the surface of the telescopic benchmark 1, and the auxiliary block 11 will also slide in the groove 10, and data can be read through the position corresponding to the floating block 3 and the scale line 9.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
