Description

Technical Field

[0001] The utility model relates to the technical field of water depth measurement, in particular to an engineering water depth measuring instrument. Background Art

[0002] Bathymetry is a basic method of underwater topography. It determines the plane position of each point on the bottom of the water and its depth below the water surface. It is a basic means of seaway measurement and seabed topography measurement. Especially in the process of water conservancy project construction, in order to ensure the safety of subsequent construction, the selection of the site is required to be high. Relevant surveys must be conducted for geology and hydrology. Data such as water quality, riverbed sediment, water volume, depth, etc. need to be collected and summarized in order to better analyze the site and determine whether it is suitable for subsequent water conservancy project construction;

[0003] Existing water depth measurement equipment generally uses ropes to lower the electronic depth measuring device into the water. However, due to the lack of a quick lowering structure, the electronic measuring device is easily impacted by waves during the lowering process, and then tilted away from the pre-positioning, reducing its measurement accuracy.

[0004] The existing patent (publication number: CN216206315U) is an automatic water depth measuring device for water conservancy projects. When in use, the supporting column component is installed on the hull, and the hydraulic lifting rod extends the lifting support arm to a horizontal state. During the extension process, the hydraulic lifting rod drives the stroke slider to move in the stroke groove, and the positioning rod can make the stroke slider move and position, and the extrusion spring can shock-absorb the stroke slider; the driving motor is started on the hinged ear plate, driving the first winding wheel to rotate, thereby lowering the depth measuring rope and placing the electronic measuring device in deep water. During the sinking, two driving rotary blade fans rotate on the outer wall of the electronic measuring device, thereby acting as a propeller, and then driving the electronic measuring device to sink rapidly. During the rapid sinking process, the impact of water waves can be reduced, thereby reducing the inclination of the electronic measuring device, so that the electronic measuring device can sink vertically to the seabed quickly.

[0005] The existing patent provides a solution to the above problem. However, when the measuring device is in use, because aquatic plants grow on some parts of the bottom of the water, the aquatic plants will be entangled in the connection between the electronic measuring device and the depth measuring rope during the ascent of the electronic measuring device, which may make it difficult to fold up the electronic measuring device. Forced folding may easily cause damage to the measuring device, thereby reducing the service life of the measuring device. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 6 A water depth measuring instrument for engineering use, comprising a flat plate 1. When in use, the measuring instrument is moved to the side of a ship through a handle 19 fixedly connected to one side of the upper surface of the flat plate 1 and a universal wheel 18 on the lower surface of the flat plate 1, and then an electric telescopic rod 5 fixed to one side of a mounting column 2 fixed to the upper surface of the flat plate 1 is started to extend the electric telescopic rod 5, and a support rod 15 fixedly connected between the electric telescopic rod 5 and the mounting column 2 is used to improve the stability of the electric telescopic rod 5, and then a second motor 11 on one side of the outer surface of the mounting column 2 is started to drive a rotating shaft 3 to rotate, thereby lowering a connecting rope 4, placing a measuring head 7 in deep water, sinking the measuring head 7 to the bottom of the river, and the connecting rope 4 and the electric telescopic rod 15 are connected. The No. 1 pulley 13 in the mounting block 12 fixedly connected to the upper surface of the retractable rod 5 and the No. 2 pulley 14 rotatably connected inside the U-shaped mounting platform 6 at one end of the electric telescopic rod 5 are both movably connected, so that the connecting rope 4 can be evenly lowered, and then the measuring head 7 can sink evenly to the river bottom, and finally the water depth is measured by the depth meter 72 in the measuring head 7, and the weight block 71 fixedly connected to the upper end of the depth meter 72 can accelerate the sinking speed of the measuring head 7, and then the battery 17 fixedly connected to the upper surface of the flat plate 1 is used to power the instruments in the measuring instrument, and the control plane 16 fixedly connected to one side of the mounting column 2 is used to facilitate the control of the measuring instrument.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, after the measuring instrument has measured the water depth, the No. 2 motor 11 is started to drive the rotating shaft 3 to rotate, so that the connecting rope 4 is recovered, and the measuring head 7 is retracted upward. However, when the measuring head 7 moves upward, water plants will be entangled in the connection between the measuring head 7 and the connecting rope 4, which may make it difficult to retract the measuring head 7. Forcible retraction may easily cause damage to the measuring instrument. Therefore, a cutting mechanism 8 is provided on the upper surface of the weight block 71. First, the No. 1 motor 87 fixedly connected to the installation cavity 86 opened inside the weight block 71 is started, and then the gear 85 fixedly connected to the output end of the No. 1 motor 87 is driven to rotate in the cavity 83 opened in the weight block 71, and then the internal gear 84 meshing with the gear 85 is driven to rotate, thereby driving the annular slider 82 fixedly connected to the internal gear 84 to rotate in the annular slide groove 81 opened on the upper surface of the weight block 71, and finally The cutting blade 88 arranged on one side of the upper surface of the annular slider 82 is driven to rotate. The water plants entangled at the connection between the measuring head 7 and the connecting rope 4 can be cut through the rotation of the cutting blade 88, so as to prevent the water plants from being entangled at the connection between the measuring head 7 and the connecting rope 4, thereby preventing the measuring head 7 from being entangled by the water plants when rising, causing damage to the measuring head 7, thereby improving the service life of the measuring instrument, and then through the sealing rings 89 fixedly connected on both sides of the inner surface of the annular slide groove 81, and the two sealing rings 89 are fitted with the annular slider 82, the overall sealing of the cutting mechanism 8 can be improved, and the river water can be prevented from entering the cutting mechanism 8 when the cutting mechanism 8 is used in the river water and affecting the use of the cutting mechanism 8, and the outer surface of the connecting rope 4 is fixedly connected to the weight block 71 with a protective cover 10, which can prevent the cutting blade 88 from scratching the connecting rope 4 when rotating.

[0031] like Figure 6As shown, when the measuring instrument is not in use, the cutting blade 88 is directly exposed to the air, which is not only easy to cause damage to the cutting blade 88, but also the cutting blade 88 may scratch the user. Therefore, a storage mechanism 9 is set inside the annular slider 82. When the measuring instrument is not in use, the moving block 97 is first moved to drive the annular slider 82 fixedly connected to the moving block 97 to move in the No. 2 slide groove 94 opened on the upper surface of the annular slider 82, and then the No. 1 slider 92 inside the No. 1 slide groove 91 opened on the upper surface of the annular slider 82 is driven to move downward, thereby driving the cutting blade 88 fixedly connected to the upper surface of the No. 1 slider 92 to move downward, and at the same time, the storage groove 96 opened on the lower surface of the No. 2 slider 95 causes the cutting blade 88 to move to the storage groove 9 6, and thus can protect the cutting blade 88. When it is needed, the moving block 97 is moved in the opposite direction, and the spring 93 drives the No. 1 slider 92 to move upward, so that the cutting blade 88 moves upward, so that the measuring instrument can store the cutting blade 88 in the No. 1 slide groove 91 when not in use. At the same time, the No. 2 slider 95 can protect the cutting blade 88 to prevent the cutting blade 88 from being exposed to the air and causing damage, thereby increasing the service life of the cutting blade 88, thereby further increasing the service life of the measuring instrument. In addition, the sealing gasket 98 fixedly connected to the upper surface of the No. 2 slide groove 94 improves the sealing performance of the storage mechanism 9, preventing river water from entering the storage mechanism 9 and affecting the use of the storage mechanism 9.

[0032] Working principle: When the present application is used, the measuring instrument is first moved to the side of the boat by means of the handle 19 and the universal wheel 18, and then the electric telescopic rod 5 is started to extend the electric telescopic rod 5, and then the No. 2 motor 11 is started to drive the rotating shaft 3 to rotate, thereby lowering the connecting rope 4, placing the measuring head 7 in deep water, and sinking the measuring head 7 to the bottom of the river, and then the water depth is measured by the depth measuring device 72 in the measuring head 7. When the measuring instrument has measured the water depth, the No. 2 motor 11 is started to drive the rotating shaft 3 to rotate, so that the connecting rope 4 is recovered, so that the measuring head 7 is retracted upward, and at the same time, the No. 1 motor 87 is started to drive the gear 85 The inner gear 84 is then driven to rotate, thereby driving the annular slider 82 to rotate in the annular slot 81, and finally driving the cutting blade 88 to rotate. The waterweed entangled at the connection between the measuring head 7 and the connecting rope 4 can be cut by the rotation of the cutting blade 88. When the measuring head 7 is retracted, the moving block 97 drives the annular slider 82 to move, and then drives the No. 1 slider 92 to move downward, thereby driving the cutting blade 88 to move downward. At the same time, the storage groove 96 is opened on the lower surface of the No. 2 slider 95, so that the cutting blade 88 moves to the storage groove 96, thereby protecting the cutting blade 88.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
