Description

Technical Field

[0001] This utility model belongs to the field of hydrological surveying technology, and specifically relates to a hydrological surveying device. Background Technology

[0002] Hydrological surveying is an investigation and research work conducted to ascertain the hydrological conditions of a region. Its core objective is to understand the formation, distribution, and movement patterns of groundwater and surface water. In this field, hydrological surveying equipment typically needs to be used in conjunction with internally installed survey heads to analyze and detect the internal structure of water resources in order to obtain comprehensive hydrological information.

[0003] In the prior art, Chinese utility model patent (CN215677020U) discloses a portable adjustable hydrological and water resources surveying device. Its main structure includes a base and a fixing plate. A protective cover is provided on the upper end of the base. A motor is installed on the left side inside the protective cover. An adjustment box is fixed on the end face of the mounting plate. A positioning groove is opened on the right side of the adjustment box. A threaded rod is vertically rotatable in the middle of the box. The rotation of the threaded rod drives the surveying head to rise and fall to achieve surveying at different depths.

[0004] However, this existing technical solution has significant drawbacks: on the one hand, the lifting stroke of the survey head is directly limited by the length of the threaded rod. When it is necessary to survey water resources at depth in the hydrology, its survey depth is seriously insufficient, resulting in incomplete survey and analysis results. On the other hand, the waters surveyed in the hydrology are usually turbid. When the survey head is working in the water, it is very easy to get tangled or bumped by debris in the water, affecting the stability and accuracy of the survey, and may even damage the survey equipment.

[0007] In a preferred embodiment of the surveying device provided by this utility model, the adjustment component includes a movable seat and a mounting seat. The movable seat and the mounting seat are slidably connected to both sides of the inner side of the bracket. A second reduction motor is fixed inside the mounting seat.

[0008] In a preferred embodiment of the surveying device provided by this utility model, a first reduction motor is fixed to the inner side of the bracket near the second pad. A screw is fixed to the output end of the first reduction motor, and the end of the screw away from the first reduction motor passes through the movable seat and is threadedly connected to the movable seat.

[0009] In a preferred embodiment of the surveying device provided by this utility model, guide columns are symmetrically fixed at one end of the support plate near the electric telescopic rod, and both guide columns are located inside the surveying frame and are slidably connected to the surveying frame.

[0010] In a preferred embodiment of the surveying device provided by this utility model, the debris-blocking component includes an outer barrier and an inner barrier. An inner barrier is provided on the outer side of the surveying head body, and an outer barrier is provided on the outer side of the inner barrier. Both the inner barrier and the outer barrier are rotatably connected to the support plate. An outer gear ring is also fixed on the outer side of the inner barrier, and an inner gear ring is fixed on the inner side of the outer barrier. A third reduction motor is fixed inside the support plate, and a spur gear is fixed at the output end of the third reduction motor. The spur gear is located between the outer gear ring and the inner gear ring and meshes with the outer gear ring and the inner gear ring respectively.

[0011] As a preferred embodiment of the surveying device provided by this utility model, the base is also symmetrically provided with reinforcing bolts at one end near the support block.

[0012] In a preferred embodiment of the surveying device provided by this utility model, both the first pad and the second pad are made of rubber, and the upper surface of the first pad and the lower surface of the second pad are provided with anti-slip textures.

[0013] In a preferred embodiment of the surveying device provided by this utility model, the electric telescopic rod is fixedly connected to the surveying frame by bolts, and the telescopic stroke of the electric telescopic rod is greater than 1 / 2 of the length of the surveying frame.

This device is equipped with a debris-blocking component on the outside of the survey head body, consisting of an outer barrier, an inner barrier, and a gear transmission structure. The third reduction motor drives the flat gear to mesh with the outer gear ring and the inner gear ring, so that the outer barrier and the inner barrier rotate in opposite directions, forming a dynamic protection area, which can effectively intercept debris in the water and reduce its entanglement or collision with the survey head body; at the same time, the spring tie rod limiting structure between the support and the base, the guide column sliding guide structure, and the reinforcing bolts further improve the stability of the device, ensuring the reliability of the survey process and the service life of the equipment.

[0028] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0029] like Figure 1As shown, a hydrological survey device includes a base 1. Supports 3 and blocks 8 are fixed at both ends of the upper end of the base 1, respectively. A support shaft 4 is fixed inside the support 3. A bracket 5 is rotatably connected to the outside of the support shaft 4. A pull rod 9 is slidably connected to the inside of the block 8. One end of the pull rod 9 is located inside the bracket 5 and is slidably connected to the bracket 5. A spring 10 is fixed between the outside of the other end of the pull rod 9 and the block 8. A first pad 6 and a second pad 7 are fixed at the upper and lower ends of the bracket 5, respectively. A rotating shaft 16 is also provided inside the bracket 5. An adjustment assembly is provided between the bracket 5 and the rotating shaft 16. A survey frame 17 is fixed outside the rotating shaft 16. An electric telescopic rod 18 is fixed at the center of the inner side of the survey frame 17. A support plate 19 is fixed at the telescopic end of the electric telescopic rod 18. A survey head body 21 is provided at the center of the end of the support plate 19 away from the electric telescopic rod 18. A debris-blocking assembly is provided at the end of the support plate 19 away from the electric telescopic rod 18 and outside the survey head body 21.

[0030] The surveying device provided by this utility model can control the depth of descent of the surveying head body 21 by controlling the tilting degree of the surveying frame 17. When the rotating shaft 16 rotates 90 degrees, the surveying frame 17 is in a vertical state. At this time, the electric telescopic rod 18 can be used to drive the surveying head body 21 to descend further, effectively increasing the surveying depth. In addition, the debris-blocking component can be used to protect the surveying head body 21 during the surveying process, effectively reducing the risk of the surveying head body 21 being entangled or bumped by debris.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0033] Please refer to Figure 1-6 A hydrological survey device includes a base 1. Supports 3 and blocks 8 are fixed at both ends of the upper end of the base 1. A support shaft 4 is fixed on the inner side of the support 3. A bracket 5 is rotatably connected to the outer side of the support shaft 4. Before the bracket 5 is rotated around the support shaft 4, a pull rod 9 is slidably connected to the inner side of the block 8 to facilitate the limiting and fixing of the bracket 5. One end of the pull rod 9 is located inside the bracket 5 and slidably connected to the bracket 5. A spring 10 is fixed between the outer side of the other end of the pull rod 9 and the block 8.

[0034] The upper and lower ends of the bracket 5 are respectively fixed with a first pad 6 and a second pad 7. When the bracket 5 is not flipped, the second pad 7 fits against the base 1 to support the bracket 5. When the bracket 5 is flipped, the first pad 6 fits against the base 1 to support the bracket 5. In order to improve the stability of the base 1 during the survey, the base 1 is also symmetrically equipped with reinforcing bolts 2 at the end near the support block 8.

[0035] The inner side of the bracket 5 is also provided with a rotating shaft 16. In order to facilitate the control of the rotation of the rotating shaft 16, an adjustment component is provided between the bracket 5 and the rotating shaft 16.

[0036] Specifically, the adjustment assembly includes a movable seat 13 and a mounting seat 14. The movable seat 13 and the mounting seat 14 are slidably connected to the two sides of the inner side of the bracket 5, respectively. A second reduction motor 15 is fixed inside the mounting seat 14. One side of the rotating shaft 16 is fixed to the output end of the second reduction motor 15, and the other side of the rotating shaft 16 is rotatably connected to the movable seat 13.

[0037] A survey frame 17 is fixed to the outside of the rotating shaft 16. An electric telescopic rod 18 is fixed to the center of the inner side of the survey frame 17. A support plate 19 is fixed to the telescopic end of the electric telescopic rod 18. A survey head body 21 is set at the center of the end of the support plate 19 away from the electric telescopic rod 18. When the rotating shaft 16 rotates, it drives the survey frame 17 to rotate around the rotating shaft 16 as the axis, thereby driving the survey head body 21 to move down to the water for survey. When the rotating shaft 16 rotates ninety degrees, the survey frame 17 is in a vertical state. At this time, with the help of the electric telescopic rod 18, it is convenient to further increase the survey depth of the survey head body 21.

[0038] When the electric telescopic rod 18 is activated to move the support plate 19 downward, in order to make the movement of the support plate 19 more stable, guide posts 20 are symmetrically fixed at one end of the support plate 19 near the electric telescopic rod 18. Both guide posts 20 are located inside the survey frame 17 and are slidably connected to the survey frame 17.

[0039] During the surveying process through the surveying head body 21, in order to facilitate the blocking of debris on the outside of the surveying head body 21, a debris blocking component is provided at the end of the support plate 19 away from the electric telescopic rod 18 and on the outside of the surveying head body 21.

[0040] Specifically, the debris-blocking assembly includes an outer perimeter baffle 22 and an inner perimeter baffle 24. An inner perimeter baffle 24 is provided on the outer side of the survey head body 21, and an outer perimeter baffle 22 is provided on the outer side of the inner perimeter baffle 24. Both the inner perimeter baffle 24 and the outer perimeter baffle 22 are rotatably connected to the support plate 19. An outer gear ring 25 is also fixed on the outer side of the inner perimeter baffle 24, and an inner gear ring 23 is fixed on the inner side of the outer perimeter baffle 22. A third reduction motor 26 is fixed inside the support plate 19. A spur gear 27 is fixed at the output end of the third reduction motor 26. The spur gear 27 is located between the outer gear ring 25 and the inner gear ring 23 and meshes with the outer gear ring 25 and the inner gear ring 23 respectively. Example

[0041] The surveying device provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, in order to facilitate the movement of the rotating shaft 16 inside the bracket 5, a first reduction motor 11 is fixed on the inner side of the bracket 5 near the second pad 7. A screw 12 is fixed on the output end of the first reduction motor 11. The end of the screw 12 away from the first reduction motor 11 passes through the movable seat 13 and is threadedly connected to the movable seat 13.

[0042] Meanwhile, when the survey frame 17 is in a vertical state, the first reduction motor 11 is driven to control the rotating shaft 16 to move inside the support 5, thereby facilitating the adjustment of the survey position of the survey head body 21.

[0043] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0044] The process of using the surveying device provided by this utility model is as follows: After the base 1 is placed at the survey location, the position of the base 1 is limited and fixed by the reinforcing bolt 2. Pull the pull rod 9 to slide it out from the bracket 5 to release the limitation on the bracket 5, so that the bracket 5 is flipped so that the first pad 6 fits against the base 1 to support the bracket 5. At this time, the second reduction motor 15 is started to drive the rotating shaft 16 to rotate, so that the surveying frame 17 is flipped and tilted around the rotating shaft 16 as the axis. By controlling the degree of tilt of the surveying frame 17, it is convenient to control the surveying depth of the surveying head body 21.

[0045] When the survey frame 17 is in a vertical position, the electric telescopic rod 18 is activated to facilitate the support plate 19 to continue to move downward through the guide column 20, thereby further increasing the survey depth of the survey head body 21. At the same time, the first reduction motor 11 is activated to drive the screw 12 to rotate, which facilitates the sliding of the moving seat 13 inside the bracket 5, thereby adjusting the position of the rotating shaft 16 and thus adjusting the survey position of the survey head body 21.

[0046] Furthermore, during the survey process, the third reduction motor 26 is activated to drive the spur gear 27 to rotate. Through the meshing of the spur gear 27 with the inner gear ring 23 and the outer gear ring 25 respectively, it is convenient to drive the outer perimeter 22 and the inner perimeter 24 to rotate synchronously. Moreover, the outer perimeter 22 and the inner perimeter 24 rotate in opposite directions, which makes it convenient to block debris on the outside of the survey head body 21.

[0047] It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
