[0028] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0029] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] See Figure 1-6 This is one embodiment of the anti-collision protection device for surveying instruments according to the present invention.

[0031] It includes a tripod 1 and a surveying instrument 2 mounted on the upper end of the tripod 1; wherein, a mounting plate 3 is provided on the upper end of the tripod 1, the surveying instrument 2 is fixed on the mounting plate 3, and a protective cover 4 is rotatably mounted on the mounting plate 3;

[0032] The protective cover 4 is composed of a front plate 41, a rear plate 42, a side plate 43 and a top plate 44. A rotating shaft 5 is provided near the corner of the front plate 41. The rotating shaft 5 is keyed to the front plate 41 and rotatably connected to the mounting plate 3.

[0033] When using the surveying instrument 2, it is usually supported by the tripod 1. If the tripod 1 is not placed on an uneven surface or is bumped by staff or other objects, it may become unstable and tip over. If the tripod 1 tipps over, it will cause the surveying instrument 2 on top to fall to the ground. This will not only increase the project cost but also affect the progress of the surveying project. Therefore, in order to prevent the above situation from happening, this device is equipped with a protective cover 4. The protective cover 4 is mainly used to cover the outer perimeter of the surveying instrument 2. If the surveying instrument 2 and the tripod tip over, the protective cover 4 can effectively protect the surveying instrument 2 and avoid greater economic losses.

[0034] The protective cover 4 is very easy to use. The staff only needs to manually move the protective cover 4, and the protective cover 4 will cover the surveying instrument 2 under the rotation of the rotating shaft 5. The front plate 41, rear plate 42, side plate 43 and top plate 44 on the protective cover 4 provide protection for the surveying instrument 2.

[0035] After the front plate 41, rear plate 42, side plate 43, and top plate 44 are placed on the surveyor 2, they form a protective space with an opening on one side together with the mounting plate 3 at the bottom, which can provide a good protection for the surveyor 2. The device model in this model does not have a protective plate similar to the side plate 43 in the direction of the laser measuring lens of the surveyor 2. Of course, the optional model is equipped with a protective plate similar to the side plate 43, which has a hole in the middle for the laser to pass through.

[0036] Rubber shock-absorbing pads 6 are arranged on the front end face of the front panel 41 and the rear end face of the rear panel 42.

[0037] The device has rubber shock-absorbing pads 6 installed on the vertical surfaces of the front plate 41 and the rear plate 42. When it is tilted, the rubber shock-absorbing pads 6 will contact the ground first, which can absorb part of the impact and help protect the surveying instrument 2.

[0038] Since the entire surveying instrument 2 is placed in a space with a single-sided opening formed by the protective cover 4 and the mounting plate 3, the heat dissipation effect is greatly reduced. In order to improve the heat dissipation of the surveying instrument 2, a ventilation slot 4423 is provided in the top plate 44.

[0039] Meanwhile, since this equipment is installed outdoors, in order to prevent rainwater from directly entering the protective cover 4 through the ventilation slot 4423 when it rains or snows, the structure of the top plate 44 has been improved.

[0040] Specifically, the top plate 44 is composed of an arc plate 441 and V-shaped plates 442 arranged on both sides of the arc plate 441. The V-shaped plates 442 are fixedly connected to the front plate 41 and the rear plate 42. The V-shaped plates 442 include a first inclined plate 4421 connected to the arc plate 441 and a second inclined plate 4422 connected to the front plate 41 or the rear plate 42, and the tip of the V-shaped plates 442 faces the inside of the protective cover 4. Several ventilation grooves 4423 are evenly arranged on the first inclined plate 4421.

[0041] The arc plate 441 in this device allows rainwater to flow directly down the arc surface, while the V-shaped plate 442 facilitates the installation of the ventilation groove 4423. The structure of the V-shaped plate 442 and the position of the ventilation groove 4423 prevent rainwater from entering the protective cover 4 through the ventilation groove 4423. The first inclined plate 4421 and the second inclined plate 4422 form a space, allowing rainwater to slide directly down the arc plate 441 during rain without entering this space.

[0042] The front and rear ends of the mounting plate 3 are also provided with support plates 7, and the ends of the support plates 7 are provided with limiting plates 8. A limiting groove 9 is formed between the limiting plates 8 and the mounting plate 3 for the front plate 41 or the rear plate 42 to be inserted.

[0043] The support plate 7 in this device is used on the protective cover 4 covering the surveying instrument 2. Specifically, the lower end surfaces of the front plate 41 and the rear plate 42 contact the support plate 7, so that the entire protective cover 4 is in a horizontal state. At the same time, in order to prevent the protective cover 4 from shaking, a limiting plate 8 is set to limit the position of the protective cover 4.

[0044] A rubber sheet 10 is provided on the limiting plate 8 facing the limiting groove 9.

[0045] The rubber sheet 10 in this device is designed to withstand impacts and can reduce the impact force on the front plate 41 or the rear plate 42.

[0046] The lower end face of the mounting plate 3 is provided with a support member 11, which includes a vertical plate 111 and a horizontal plate 112 disposed below the vertical plate 111.

[0047] The support 11 in this device is used to limit the opening of the protective cover 4, so that the protective cover 4 will not completely flip over; the vertical plate 111 is set to provide space for the rotation of the protective cover 4, and the horizontal plate 112 is used to support the protective cover 4 to prevent it from flipping over excessively.

[0048] A circular arc plate 113 is provided in the middle of the horizontal plate 112 to provide normal rotation space for the protective cover 4.

[0049] Since the protective cover 4 in this device rotates, its movement path is curved. The arc plate 113 is mainly provided to give it rotation space, so that the length of the vertical plate 111 is not too long.

[0050] The support plate 7, the limiting plate 8, and the support component 11 are made of stainless steel.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
