[0026] For descriptive purposes, the disclosure can use spatially relative terms, such as "below", "beneath", "lower", "under", "above", "upper" and the like, to describe a relationship of one element to another element as depicted in the figures. Unless otherwise noted, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture, for example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. For example, where an element is above another element, it can be oriented above the other element, or it can be oriented below the other element. Thus, the spatially relative terms are intended to encompass the various and ordinary orientations of the device in use, operation, and / or manufacture. The terms "first", "second", third", "fourth", etc. can be used herein to describe various elements, but example only, and the elements should not be limited by these terms. The terms "first", "second", "third", "fourth", etc. are also used in the claims to distinguish one claim from another in, for example, a multiple dependent claim type situation. For purposes of the technology, certain terms are used to describe a device or its components. Unless otherwise noted, a singular term includes plural aspects. Unless otherwise noted, a range includes its minimum and maximum values. Unless otherwise indicated, any reference to a method using terms such as "comprising", "including" or "having" means that the method includes a stated step, integer, operation, element, component or limitation but not excluding the presence or addition of one or more other steps, integers, operations, elements, components, or limitations that are to the method.

[0027] As shown in Figures 1-3 The foundation pit horizontal displacement detection device with high-precision sensor of the present disclosure can include a synchronous displacement mechanism 1, a detection alarm mechanism 2, and a storage type fixing mechanism 3, etc.

[0028] As shown in Figure 2 In the present disclosure, the synchronous displacement mechanism 1 includes a bottom plate 11, a fixed frame 12, a sliding shaft 13, a fitting plate 14, and a reset spring 15. The fixed frame 12 is fixedly arranged on the top of the bottom plate 11. The sliding shaft 13 penetrates the fixed frame 12 in the horizontal direction and is in sliding connection with the fixed frame 12. The fitting plate 14 is fixedly arranged on the left end of the sliding shaft 13. The reset spring 15 is sleeved on the outside of the sliding shaft 13 and is fixedly connected between the fixed frame 12 and the fitting plate 14.

[0029] In this way, the fitting plate 14 is fitted to the inner wall of the foundation pit and the installation and fixation of the device are completed. Subsequently, when the inner wall of the foundation pit is horizontally displaced, the fitting plate 14 is synchronously displaced due to the pushing of the inner wall of the foundation pit. When the fitting plate 14 is displaced, the sliding shaft 13 is synchronously moved on the fixed frame 12 and the reset spring 15 is compressed.

[0030] As shown in Figure 2 In a preferred embodiment, the detection alarm mechanism 2 includes a control box 21, a buzzer 22, and high-precision sensors 23. The control box 21 is fixedly arranged on the right side of the fixed frame 12. The buzzer 22 is fixedly arranged on the top of the control box 21. The high-precision sensors 23 are provided in two, and the two high-precision sensors 23 are respectively fixedly arranged on the top and the bottom of the left side of the fixed frame 12. The two high-precision sensors 23 and the buzzer 22 are connected with the controller inside the control box 21.

[0031] Thus, in order to facilitate the setting of displacement limit value by the controller inside the control box 21, the high-precision sensor 23 continuously detects the distance between the fixed plate 14, and when the moving distance of the fixed plate 14 reaches the displacement limit value, the controller inside the control box 21 causes the buzzer 22 to alarm, thereby reminding the nearby staff.

[0032] In addition, it should be noted that the high-precision sensor 23 is set as a high-precision laser displacement ranging sensor of FSD22-30 type, and those skilled in the art can also independently select a suitable type.

[0033] As shown in Figure 3 The receiving type fixing mechanism 3 in the present disclosure includes a U-shaped base 31, a receiving groove 32, a fixing pile 33, a connecting pin 34, a torsional spring 35, a bidirectional screw rod 36, a rotating disc 37, and two moving pressure plates 38. The U-shaped base 31 is fixedly arranged at the bottom of the bottom plate 11. The receiving groove 32 is arranged on the inner side of the U-shaped base 31. The fixing pile 33 is arranged on the inner side of the receiving groove 32. The connecting pin 34 is arranged through the side of the U-shaped base 31 and extends to the inner side of the receiving groove 32 and is fixedly connected with the fixing pile 33. The torsional spring 35 is sleeved on the outer side of the connecting pin 34 and is fixedly connected between the U-shaped base 31 and the connecting pin 34. The bidirectional screw rod 36 is arranged through the inner side of the U-shaped base 31 and is rotatably connected with the U-shaped base 31 through a bearing. The rotating disc 37 is fixedly arranged on the outer side of the U-shaped base 31 and is drivingly connected with the bidirectional screw rod 36. The two moving pressure plates 38 are arranged on the outer sides of the two ends of the bidirectional screw rod 36 and are drivingly connected with the bidirectional screw rod 36. The two moving pressure plates 38 are slidingly arranged between the bottom plate 11 and the U-shaped base 31.

[0034] Thus, in the normal state, the receiving groove 32 receives the fixing pile 33, and when the fixing pile 33 needs to be used, the rotating disc 37 is rotated, the rotating disc 37 drives the bidirectional screw rod 36 to rotate synchronously, and when the bidirectional screw rod 36 rotates, the two moving pressure plates 38 are driven to move towards each other, thereby gradually releasing the pressing of the top end of the fixing pile 33 by the moving pressure plates 38. With the continuous movement of the moving pressure plates 38, the torsional spring 35 drives the fixing pile 33 to rotate out of the inner side of the receiving groove 32 and gradually rotate to the vertical state through the connecting pin 34. Compared with the prior art, the fixing pile 33 can be conveniently received in the normal state, thereby avoiding the harm of the fixing pile 33 to the operator and reducing the difficulty of moving the device, which is more convenient in actual use.

[0035] In addition, it should be noted that the contents not described in detail in the present disclosure belong to the prior art known to those skilled in the art.

[0036] Those skilled in the art should understand that the above embodiments are only for clearly illustrating the present disclosure, and are not intended to limit the scope of the present disclosure. Based on the above disclosure, other changes or modifications can also be made by those skilled in the art, and these changes or modifications are still within the scope of the present disclosure.
