Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project detection equipment, in particular to a foundation detection device for water conservancy projects. Background Technique

[0002] A water conservancy project is a general term for various engineering constructions built to control, utilize, and protect surface and underground water resources and the environment. Water conservancy projects can be divided into flood control projects, farmland water conservancy projects, hydropower projects, shipping, urban water supply, and drainage projects according to their service objects. When implementing a water conservancy project, various data need to be detected. The foundation detection device is one of the most common detection devices, which is simple to use and the data is easy to read and record.

[0003] When using the foundation detection device, the probe rod needs to be vertically inserted into the ground, that is, the probe rod needs to be perpendicular to the horizontal plane.

[0004] In order to ensure the verticality of the existing foundation detection device's probe rod, a spirit level is generally set on the base, and support rods are set at the corners of the base. The bottom end of the support rod supports on the ground. When the ground is inclined or uneven, the base is adjusted to be horizontal by adjusting the length of the support rod in cooperation with the spirit level, and then the verticality of the probe rod is ensured by the relative perpendicularity between the probe rod and the base. This structure has the following defects: First, the overall structure is only placed on the ground, and the stability is poor; Second, after the base is adjusted, the end faces of multiple support rods are not necessarily coplanar, which reduces the contact area between the base and the ground and further reduces the support stability of the base. Content of the Utility Model

[0005] To overcome the technical defect of poor support stability existing in the existing foundation detection device, the utility model provides a foundation detection device for water conservancy projects.

[0006] The foundation detection device for water conservancy projects provided by the utility model includes:

[0007] A chassis, which includes a bottom frame and at least three insertion rods fixed below the bottom frame;

[0008] A support plate, which is located above the chassis;

[0009] At least three sets of support components, each support component includes a column fixed on the bottom frame, the upper end of the column is connected with a telescopic rod through a spherical hinge, and the other end of the telescopic rod is connected to the lower surface of the support plate through a spherical hinge;

[0010] A spirit level, which is arranged on the support plate;

[0011] A sliding rod, which is slidably inserted on the support plate and is perpendicular to the support plate;

[0012] The detection component includes a detector fixed to the lower end of the sliding rod. A probe rod is provided at the lower end of the detector. The probe rod is collinear with the sliding rod, and a probe head is provided at the lower end of the probe rod.

[0013] Optionally, the telescopic rod includes two screw rods with opposite helix directions. The two screw rods respectively correspond to the two ball hinges of the support component. One end of the screw rod is connected to the corresponding ball hinge, and the other ends of the two screw rods are connected through a threaded sleeve.

[0014] Optionally, a locking nut is screwed on the screw rod.

[0015] Optionally, a guide cylinder is fixed on the upper surface of the support plate, and the sliding rod is slidably inserted into the guide cylinder.

[0016] Optionally, a handle is provided at the top end of the sliding rod.

[0017] Optionally, a first spring is provided between the handle and the top end of the guide cylinder.

[0018] Optionally, a display screen is further provided on the support plate, and the display screen is communicatively connected to the detector.

[0019] Optionally, a top support component is provided between the support plate and the bottom frame. The top support component includes a fixed cylinder fixed on the bottom frame. A top rod is slidably inserted into the fixed cylinder. A second spring is pressed between the bottom end of the top rod and the bottom end of the fixed cylinder, and the top end of the top rod abuts against the lower surface of the support plate.

[0020] Optionally, the top surface of the top rod is spherical.

[0021] The technical solution provided by the present utility model has the following advantages compared with the prior art:

[0022] For the water conservancy project foundation detection device provided by the present utility model, the base is divided into a bottom frame and a support plate. The bottom frame is inserted into the ground through the insertion rods, the support plate is connected to the bottom frame through the support component, the probe rod provided with the detector is vertically inserted on the support plate, and a spirit level is provided on the support plate. During use, the stability of the overall device is ensured through the insertion of the insertion rods; if the support plate is not level, the bottom frame inserted into the ground through the insertion rods does not need to be adjusted. Only the levelness of the support plate needs to be adjusted through the cooperation of the support component and the spirit level. After the support plate is adjusted to be level, since the sliding rod is perpendicular to the support plate, the sliding rod is in a vertical state, that is, the probe rod is in a vertical state. When adjusting the verticality of the probe rod of this device, it is not necessary to adjust the bottom frame directly connected to the ground. Only the levelness of the support plate needs to be adjusted through the support component. In this way, both the verticality of the probe rod can be satisfied and the stability of the entire device can be ensured. Description of the Drawings

[0029] In order to be able to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following will further describe the solution of the present utility model. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0030] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. It should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0031] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0032] The following specifically describes the embodiments of the present utility model in conjunction with the accompanying drawings.

[0033] Refer to Figures 1 to 2 , this embodiment provides a foundation detection device for water conservancy projects, including a chassis 1, a support plate 2, a support assembly 3, a level 4, a slide bar 5, and a detection assembly 6.

[0034] Among them, the chassis 1 includes a bottom frame 11 and at least three insertion rods 12 fixed below the bottom frame 11. When in use, the insertion rods 12 are inserted into the ground, so as to fix the chassis 1 on the ground, which is more firm.

[0035] It should be noted that since the overall device needs to be disassembled and reused after use, the insertion rods 12 can be directly inserted into the ground, and there is no need to adopt an insertion rod 12 structure with a barbed structure.

[0036] Specifically, for the convenience of inserting the insertion rods 12, the bottom ends of the insertion rods 12 can be set to be pointed.

[0037] Specifically, the bottom frame 11 includes a rectangular frame 111 and a cross strengthening beam 112 located inside the rectangular frame 111. The cross strengthening beam 112 can improve the structural strength of the bottom frame 11 on the one hand, and is also convenient for the installation of other structures on the other hand.

[0038] Specifically, there are four insertion rods 12, which are respectively arranged corresponding to the four corners of the rectangular frame of this embodiment. Of course, if the bottom frame 11 is circular or other polygons, the number of insertion rods 12 can be adaptively increased or decreased, and at least three are required.

[0039] Among them, the support plate 2 is located above the chassis 1.

[0040] It is easy to understand that the main function of the support plate 2 is to install components such as the level 4, the slide bar 5, and the detection assembly 6.

[0041] Furthermore, a guide cylinder 21 is fixed on the upper surface of the support plate 2, and the slide bar 5 is slidably inserted into the guide cylinder 21. The guide cylinder 21 can increase the length of the slide bar 5 supported by sliding, thereby improving the sliding stability of the slide bar 5.

[0042] Specifically, a handle 51 is provided at the top end of the slide bar 5, which is more conducive to pressing or pulling up the slide bar 5.

[0043] Specifically, a first spring 52 is provided between the handle 51 and the top end of the guiding cylinder 21. The first spring 52 has two functions: First, the supporting spring can overcome the gravity of the sliding rod 5 and its components thereon, so that the sliding rod 5 is supported at a set position in the natural state; Second, when the sliding rod 5 is pulled upward after the detection is completed, the supporting spring generates an upward acting force on the handle 51, playing an auxiliary role in the upward pulling action.

[0044] Furthermore, a display screen 7 is also provided on the support plate 2, and the display screen 7 is communicatively connected to the detector 61. The display screen 7 and the detector 61 can be communicatively connected by wired or wireless means. The detector 61 sends the detection result to the display screen 7 for display, making the detection result more intuitive and the use more convenient.

[0045] Among them, at least three sets of supporting components 3 are provided. The supporting component 3 includes a column 31 fixed on the bottom frame 11. The upper end of the column 31 is connected to a telescopic rod 33 through a ball hinge 32, and the other end of the telescopic rod 33 is connected to the lower surface of the support plate 2 through a ball hinge 32. During use, the levelness of the support plate 2 can be correspondingly adjusted by adjusting the length of the telescopic rod 33, and the levelness adjustment of the support plate 2 is completed by jointly adjusting multiple telescopic rods 33.

[0046] Specifically, four sets of supporting components 3 are provided, corresponding to the four corners of the rectangular plate of this embodiment respectively. Of course, if the support plate 2 is circular or other polygons, the number of the supporting components 3 can be adaptively increased or decreased, and at least three are required.

[0047] Specifically, the telescopic rod 33 includes two screw rods 331 with opposite helix directions. The two screw rods 331 at both ends respectively correspond to the two ball hinges 32 of the supporting component 3. One end of the screw rod 331 is connected to the corresponding ball hinge 32, and the other ends of the two screw rods 331 are connected through a threaded sleeve 332. During use, when the threaded sleeve 332 is screwed, because the helix directions of the two screw rods 331 are opposite, the threaded sleeve 332 will drive the two screw rods 331 to approach or move away from each other, so as to realize the telescoping.

[0048] Furthermore, a locking nut 333 is screwed on the screw rod 331. When the telescopic rod 33 is adjusted to a suitable length through the threaded sleeve 332, the locking nut 333 is screwed so that the locking nut 333 abuts against the corresponding side end face of the threaded sleeve 332. The length of the telescopic rod 33 can be locked through the cooperation of the two locking nuts 333 on both sides, thus ensuring the stability of the support of the supporting component 3 for the support plate 2.

[0049] Among them, the spirit level 4 is arranged on the support plate 2.

[0050] It is easy to understand that the spirit level 4 is mainly used to detect the levelness of the support plate 2, including the levelness in the left - right direction and the front - back direction.

[0051] Specifically, the spirit level 4 is selected as a bubble spirit level 4, which has a simple structure and is convenient to observe.

[0052] Among them, the sliding rod 5 is slidably inserted into the support plate 2 and is perpendicular to the support plate 2.

[0053] Among them, the detection component 6 includes a detector 61 fixed to the lower end of the sliding rod 5. A probe rod 62 is provided at the lower end of the detector 61. The probe rod 62 is collinear with the sliding rod 5, and a probe 63 is provided at the lower end of the probe rod 62.

[0054] In the foundation detection device for hydraulic engineering of this embodiment, a top support component 8 is further provided between the support plate 2 and the bottom frame 11. The top support component 8 includes a fixed cylinder 81 fixed to the bottom frame 11. A top rod 82 is slidably inserted into the fixed cylinder 81. A second spring 83 is pressed between the bottom end of the top rod 82 and the bottom end of the fixed cylinder 81. The top end of the top rod 82 abuts against the lower surface of the support plate 2. Since the support plate 2 is usually arranged in a long strip shape, the support strength of the support components 3 near the two ends is weak. By providing the top support component 8, the stability of the support plate 2 can be improved.

[0055] Specifically, two sets of top support components 8 are provided and are located on the cross strengthening beam 112.

[0056] Specifically, the top surface of the top rod 82 is set as a spherical surface. When the support plate 2 is inclined, the contact position between the top rod 82 and the support plate 2 will change. If the top surface of the top rod 82 is set as a plane, it is very likely that stress concentration will occur and the top end of the top rod 82 will be damaged. In this embodiment, the top surface of the top rod 82 is set as a spherical surface, which can reduce stress concentration and thus ensure the service life of the structure.

[0057] The working principle of the foundation detection device for hydraulic engineering of this embodiment is as follows:

[0058] During use, the insertion rod 12 is inserted into the ground of the foundation to be measured. If the spirit level 4 shows that the support plate 2 is not horizontal, then adjust the length of the telescopic rod 33 of the support component 3 at the corresponding position until the spirit level 4 shows that the support plate 2 has been adjusted to be horizontal. At this time, since the sliding rod 5 is perpendicular to the support plate 2, the sliding rod 5 is adjusted to a vertical state. Finally, the sliding rod 5 is pressed down by the handle 51 so that the probe rod 62 extends into the ground for detection, and the detection result is sent to the display screen 7 for display.

[0059] The above are only specific embodiments of the present utility model, enabling those skilled in the art to understand or implement the present utility model. Although the foregoing embodiments have been described in detail, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
