[0002] With the continuous improvement of technology in the field of small-scale construction, various temporary buildings have gradually entered people's lives, especially convenient temporary buildings such as vegetable sheds and outdoor tents. For these convenient temporary buildings, the stability of their connection with the ground is particularly important. Therefore, there are various types of anchor devices on the market.

[0003] However, the ground anchor devices currently on the market are mainly aimed at solving problems in large-scale engineering fields and slope stability. There are still very few ground anchor devices suitable for convenient temporary buildings on soft foundations. In addition, small ground anchor devices need to meet the requirements of simple operation, easy to carry, low-carbon and environmentally friendly, economical, and recyclable. When it is necessary to build a temporary vegetable shed or field tent, the ground anchor can be quickly fixed, and a pull line is used to connect it to the ground anchor, and finally connected to the vegetable shed and field tent structure to ensure the stability of the structure.

[0065] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0066] The implementation of the present invention is described in detail below in conjunction with preferred embodiments.

[0067] See also Figure 1-12 The present invention provides a recyclable ground anchor device suitable for soft foundation, which mainly includes: an outer sleeve 4, a rotating shaft 5, a ground-breaking blade 6, a rotating connection mechanism 8, and a ground-breaking cone 11.

[0068] Specifically, the outer sleeve 4 serves as the outer shell of the anchor device and can enter the soil; the outer sleeve 4 adopts a cylindrical structure, for example, a stainless steel pipe or an iron pipe, and the surface of the pipe body is smooth, which can easily penetrate into the soft foundation soil.

[0069] During the specific implementation, the appropriate structural dimensions are designed according to the specific usage scenario. For the anchor size of the camping tent: the diameter is 5-8cm, and the length of the entire anchor can be 20-40cm, for example, the total length is 30cm, the diameter is 6cm, two-stage, each section is 10cm long, the ground-breaking cone is 5cm, and the interval is 5cm. For the anchor size of the vegetable shed: the diameter is 8-10cm, and the length of the entire anchor can be 30-50cm, for example, the total length is 40cm, the diameter is 9cm, three-stage, each section is 8cm long, the ground-breaking cone is 10cm, and the interval is 6cm. Of course, other suitable sizes can also be designed according to the actual usage scenario.

[0070] The outer sleeve 4 is hollow inside, and the rotating shaft 5 is arranged in the outer sleeve 4 through the entire length, but its top end is exposed outside the outer sleeve 4, so as to connect a driving mechanism, and the rotating shaft 5 can be driven to rotate by the driving mechanism. It is easy to understand that the rotating shaft 5 rotates in the outer sleeve 4, but the outer sleeve 4 remains fixed.

[0071] A plurality of soil-breaking blades 6 are arranged on the rotating shaft 5. The plurality of soil-breaking blades 6 are arranged at intervals along the height direction of the rotating shaft 5 and connected to the rotating shaft 5. The plurality of soil-breaking blades 6 are arranged at the same intervals on the rotating shaft 5. Figure 1 In the figure, three groups of earth-breaking blades 6 are arranged. When working, the multiple groups of earth-breaking blades 6 are deployed to a predetermined position when the rotating shaft 5 is driven by the driving mechanism to rotate in a first rotation direction (for example, forward rotation). Figure 7-8 As shown, at the predetermined position, the earth-breaking blades 6 extend beyond the boundary of the outer sleeve 4 and enter the soil. When the rotating shaft 5 is driven by the driving mechanism to rotate in the second rotation direction (e.g., reverse), the plurality of earth-breaking blades 6 are recovered to the initial position. At the initial position, the earth-breaking blades 6 do not extend beyond the boundary of the outer sleeve 4. Figure 9-10 As shown, the entire ground anchor device can be anchored in the foundation soil and pulled out for recovery.

[0072] It is easy to understand that the earth-breaking blade 6 can be retracted and re-anchored after properly adjusting the depth when encountering a stratum that cannot be anchored, which is incomparable to the traditional umbrella-shaped anchor device.

[0073] In order to realize that the rotating shaft 5 drives the earth-breaking blades 6 for smooth opening and recovery, a rotating connection mechanism 8 is respectively connected to the rotating shaft 5 and the earth-breaking blades 6 to drive multiple groups of earth-breaking blades 6 to be opened and recovered through the rotation of the rotating shaft 5.

[0074] The present invention also provides a soil breaking cone 11 at the bottom of the outer sleeve 4. The soil breaking cone 11 is a conical structure and is fixedly connected to the bottom of the outer sleeve 4 so as to penetrate the soil and reach a predetermined depth. The soil breaking cone 11 can be an independent structure and welded to the outer sleeve 4, or it can be integrally formed with the outer sleeve 4. Figure 1 It is shown as an independent structure, which is convenient for replacement after damage or dullness.

[0075] In some embodiments of the present invention, see Figure 2 The ground anchor device further comprises a lifting ring cover 1. Since the top of the rotating shaft 5 is exposed outside the outer sleeve 4, the lifting ring cover 1 is used to cover the top of the outer sleeve 4 to close the interior when not in use.

[0076] At the same time, the lifting ring cover 1 is provided with a lifting ring, which can be used to connect one end of the cable, and the other end of the cable is connected or tightened to light buildings such as vegetable sheds and field tents. In addition, the lifting ring can also be lifted by a light lifting device when the anchor device is heavy or long.

[0077] In some embodiments of the present invention, see Figure 3 The ground anchor device also includes a threaded seat 3, which is welded to the top of the outer sleeve 4. The corresponding lifting ring cover 1 has an internal thread for threaded connection with the threaded seat 3, which is convenient for connection and disassembly.

[0078] In some embodiments of the present invention, see Figure 3-5The anchor device also includes a rotating connection 2, which is arranged at the top of the rotating shaft 5 and is also exposed outside the outer sleeve 4. The rotating connection 2 is welded to the rotating shaft 5 and is suitable for docking with the driving mechanism. When driven to rotate by the driving mechanism, it can drive the rotating shaft 5 to rotate synchronously.

[0079] The structural form of the rotary connection 2 can be varied and can be flexibly designed according to the driving force of the driving mechanism. For example, in the case of a small motor or motor drive, the rotary connection 2 can be a shaft sleeve to connect to the motor.

[0080] For light anchors mainly used in light buildings such as vegetable sheds and outdoor tents, the present invention designs the rotating connection 2 to be a simple I-shaped clamp, which is fixed or detachably connected to the top of the rotating shaft 5, and is equipped with a I-shaped slot wrench 12 as a matching driving mechanism. The I-shaped slot wrench 12 is L-shaped, or called a pipe shape, with a I-shaped slot matching the I-shaped clamp on the bottom surface of one end, and the other end serves as a force-applying end. When in use, the I-shaped slot is clamped into the I-shaped clamp, and the rotating shaft 5 is driven to rotate by manually turning the wrench. This is extremely convenient for the use scenario of the present invention, without the need for large or electric driving machinery, and manual work can be performed anytime and anywhere, and the operation is simple and easy.

[0081] Continue to see Figure 1 , 6 In some embodiments of the present invention, a favorable outer sleeve structure is designed. The outer sleeve 4 is designed as a segmented structure, which is composed of multiple sleeve segments connected axially. Different numbers of segments can be flexibly welded as needed to obtain the required anchor length.

[0082] A hollow interval is formed between adjacent sleeve sections when connected, and a group of earth-breaking blades 6 and a group of rotating connection mechanisms 8 are arranged in the interval, so that the earth-breaking blades 6 can be extended from the interface range of the outer sleeve 4 when opened. The size of the interval, that is, the distance of the interval, is reasonably set according to the size of the earth-breaking blades 6 and the rotating connection mechanism 8. The interval should not be too large, because if it is too large, soil will enter during the process of driving into the body layer, affecting the flexibility of the drive. The interval should not be too small, because if it is too small, it will be unfavorable for the activity of the rotating connection mechanism 8 and the smooth extension of the earth-breaking blades 6, and it will also be unfavorable for the installation of the blades.

[0083] In the present invention, the following specific connection method is adopted between adjacent sleeve sections. The present invention provides an outer sleeve connecting block 10, and multiple outer sleeve connecting blocks 10 extend from the top or bottom of the sleeve section in the interval and correspond one to one, that is, multiple outer sleeve connecting blocks 10 extend from the bottom of the upper sleeve section, and multiple outer sleeve connecting blocks 10 extend from the top of the lower sleeve section. The upper and lower multiple outer sleeve connecting blocks 10 correspond one to one. The number of outer sleeve connecting blocks 10 is flexibly designed according to the number of blades and the diameter of the outer sleeve 4. Three blocks are designed in the present invention. The shape of the outer sleeve connecting block 10 adopts an annular block according to the cylindrical cross-section of the outer sleeve 4, and the three annular blocks are evenly distributed around the hollow inner cavity of the outer sleeve 4.

[0084] At the same time, the present invention is also provided with a plurality of blade clamps 7, and the number of blade clamps 7 corresponds to the outer sleeve connection block 10. On the one hand, the blade clamps 7 serve as a connection structure, that is, a plurality of blade clamps 7 are arranged one by one between two upper and lower adjacent outer sleeve connection blocks 10, and are welded and fixed to the two upper and lower adjacent outer sleeve connection blocks 10, so that the two upper and lower adjacent outer sleeve connection blocks 10 are connected together, thereby connecting and fixing the upper and lower sleeve sections, and realizing the multi-section structural design of the outer sleeve 4.

[0085] On the other hand, the blade clamp 7 serves as an installation structure for the earth-breaking blade 6 . Each blade clamp 7 clamps one earth-breaking blade 6 . Multiple earth-breaking blades 6 are clamped and connected in the blade clamp 7 one by one, thereby realizing the installation of the earth-breaking blade 6 .

[0086] Specifically, the root of each earth-breaking blade 6 is hingedly connected to a blade clamp 7, and the blade body of each earth-breaking blade 6 is hingedly connected to a rotating connection mechanism 8, so that when the rotating connection mechanism 8 is actuated, the earth-breaking blade 6 is driven to rotate with its root as the base point, thereby extending and retracting.

[0087] Preferably, the blade fixture 7 is provided with bolt holes, such as Figure 6 As shown, the root of the earth-breaking blade 6 is also provided with a bolt hole. The root of each earth-breaking blade 6 is clamped by a blade clamp 7 and then connected and fixed by a blade clamp bolt 9 passing through the blade clamp 7 and the bolt hole on the earth-breaking blade 6, as shown in FIG. Fig. 9 As shown, in this way, the earth-breaking blade 6 can be detachably installed while realizing the hinged connection, so as to facilitate on-site installation and replacement at any time.

[0088] See also Figure 6 , 79. In some embodiments of the present invention, the blade clamp 7 is a transversely placed N-shaped cross-section box structure, that is, the N-shaped cross-section box structure is placed upside down, and the root of the earth-breaking blade 6 is inserted into the blade clamp 7 from the open side of the N-shaped cross-section, and the outer side of the earth-breaking blade 6 corresponds to the top side of the N-shaped cross-section, so that the top side of the N-shaped cross-section serves as a partition (baffle), and when the earth-breaking blade 6 is unfolded to a predetermined position, it is blocked and cannot rotate anymore, so that the opening state and opening degree of the blade in the underground soil can be grasped.

[0089] It is easy to understand that by installing the earth-breaking blade by a box-type blade clamp, installing it inside, rather than the traditional direct pin connection or riveting on the outside, the stability of the blade during long-term repeated use is ensured, and the difficulty of movement due to deviation in the blade movement process is avoided.

[0090] See also Fig. 9 , 11 12. In some embodiments of the present invention, a preferred rotating connection mechanism 8 is provided, which is a three-section crank-connecting rod structure, consisting of a first connecting rod 81, a second connecting rod 82 and a third connecting rod 83. The first connecting rod 81 is relatively short, and its end close to the rotating shaft 5 is fixedly connected to the rotating shaft 5, for example, welded and fixed, and follows the rotation of the rotating shaft 5. The second connecting rod 82 is relatively long, and its end close to the first connecting rod 81 is hingedly connected to the other end of the first connecting rod 81, for example, by bolting or riveting, and the other end of the second connecting rod 82 is close to the earth-breaking blade 6 and is hingedly connected to the blade body of the earth-breaking blade 6, for example, by bolting or riveting. The third connecting rod 83 is also relatively short, and its end close to the second connecting rod 82 is hingedly connected to the other end of the second connecting rod 82, and the other end is hingedly connected to the blade clamp 7 at the root of the earth-breaking blade 6.

[0091] It should be noted that the other end of the second connecting rod 82 is hingedly connected to the blade body of the earth-breaking blade 6, and the connection position is set in the middle of the blade body or near the root 1 / 3 position to ensure that the blade body can be extended smoothly without preventing the blade body from having enough length to extend into the soil.

[0092] When the three-section crank connecting rod structure is opened, the first connecting rod 81 pushes the second connecting rod 82, and the second connecting rod 82 pushes the blade body of the earth-breaking blade 6 to rotate with its root as a base point so as to open and extend into the soil.

[0093] At the same time, with the help of the third connecting rod 83, one end of which is hinged to the blade clamp 7 together with the ground-breaking blade 6 at the root of the ground-breaking blade 6. Compared with only the root being hinged to the blade clamp 7, when the ground-breaking blade 6 is pushed, it can ensure smooth follow-up and is not easy to be difficult to extend and retract due to eccentric force or skewed structure.

[0094] The anchoring method of the ground anchor device of the present invention comprises the following steps:

[0095] S10: manually pressing down or hammering the top lifting ring cover 1 to drive the bottom breaking cone 11 into the soil until the whole structure reaches the predetermined burial depth;

[0096] S20: The driving mechanism docks with the rotary connection 2, and drives the rotary shaft 5 to rotate in the first rotation direction through the rotary connection 2. The rotary shaft 5 drives the internal rotary connection mechanism 8 to unfold, thereby driving the earth-breaking blade 6 to rotate and unfold to a predetermined position to enter the soil, thereby penetrating into the soil layer to form an anchoring effect;

[0097] S30: Tie the cable to the lifting ring and anchor the equipment;

[0098] S40: After the anchoring is completed, the driving mechanism drives the rotating shaft 5 to rotate in the second rotation direction, driving the rotating connecting mechanism 8 to contract, thereby driving the earth-breaking blade 6 to retract and return to the initial state;
