[0002] Angle measuring devices used in engineering surveys usually refer to instruments or equipment used to measure horizontal and vertical angles. These devices can be traditional goniometers, total stations, laser levels, digital levels, etc. They are usually used in civil engineering, construction engineering, road construction and other fields to ensure the horizontality and verticality of buildings, structures or ground. Existing measuring devices are generally equipped with corresponding shells for the assembly and protection of their internal components. At the same time, in order to dissipate heat and ventilate the internal components, they are generally equipped with heat dissipation holes and heat dissipation slots.

[0003] With respect to the above-mentioned related technologies, the inventor believes that although the existing measuring devices are all provided with corresponding protective shells, since most engineering surveys are conducted outdoors, especially in rainy or hot weather, rainwater may penetrate into the measuring device through the gaps in the shell and the heat dissipation slots, thereby possibly damaging its internal components and affecting its service life. At the same time, during long-term measurement operations in a high-temperature environment, its internal components may be affected by the high temperature, resulting in overheating of its internal related components, which may also cause short-circuit damage to the internal components, etc.;

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an angle measuring device for engineering survey. Figure 1-3 An angle measuring device for engineering surveying includes a measuring instrument body 1, a top cover 2 is fixedly connected to both sides of the measuring instrument body 1 by bolts, a plurality of ventilation slots 9 are provided on the top of the top cover 2, a sealing member is provided inside the plurality of ventilation slots 9, a hook 8 is fixedly connected to one side of the top cover 2 by bolts, a control box 4 is fixedly connected to the side of the top cover 2 near the hook 8 by bolts, a fixing rod 13 is rotatably connected to the inner cavity side wall of the top cover 2 by a rotating shaft, a front cover 3 is fixedly connected to the surface of the fixing rod 13 by bolts, and one end of the fixing rod 13 is rotatably connected to the inner cavity side wall of the top cover 2 by a rotating shaft The fixing rod 13 is rotated through the top cover 2 and extends to the inside of the control box 4. A brake is provided on the surface of the fixing rod 13, and the brake is arranged inside the control box 4. The sealing member includes a fixing plate 6, a handle 7, a fixing strip 14 and an elastic sealing gasket 15. The inner cavity side walls of several groups of ventilation slots 9 are all clamped with elastic sealing gaskets 15. The inner cavity side walls of several groups of elastic sealing gaskets 15 are all fixedly connected with fixing strips 14. The tops of several groups of fixing strips 14 are fixedly connected with fixing plates 6 by bolts. The tops of the fixing plates 6 are fixedly connected with two groups of handles 7 by bolts.

[0020] By adopting the above technical solution, the top cover 2 and the front cover 3 fixed on the measuring instrument body 1 can be made of certain high-strength engineering plastics (such as polycarbonate, polyamide, etc.) to provide sufficient strength and have certain heat insulation and waterproof properties. There is also a corresponding gap between the top cover 2 and the measuring instrument body 1, and a plurality of ventilation slots 9 are provided on the top cover 2, which can achieve good ventilation and heat dissipation effects while providing heat insulation. At the same time, in some rainy weather, the fixing plate 6 can be pressed to press the fixing strip 14 and the elastic sealing gasket 15 into the ventilation slot 9, and the ventilation slot 9 can be sealed. The instrument body 1 is sealed to prevent rainwater from entering the ventilation slot 9 through the ventilation slot 9. At the same time, when there is no need to seal, the two sets of handles 7 can be used to pull it out of the ventilation slot 9 as a whole, and the handles 7 can be hung on the hooks 8 to store it. The rotation of the brake inside the control box 4 can drive the fixed rod 13 connected to the inner cavity side wall of the top cover 2 to rotate, so that the angle of the front cover 3 can be adjusted, which is convenient for adjusting it according to the wind direction in rainy weather, so as to better block wind and rain and prevent rainwater from dripping directly onto the eyepiece and affecting the normal measurement operation of the staff.

[0021] Reference Figure 1 and Figure 2 The brake member includes a connecting rod 10, a worm 11, a fan-shaped worm gear 12 and a knob 5. One end of a fixed rod 13 passes through the top cover 2 and is rotatably connected to the inner cavity side wall of the control box 4 through a rotating shaft. The surface of the fixed rod 13 is rotatably connected to the fan-shaped worm gear 12 through a rotating shaft. The surface of the fan-shaped worm gear 12 is meshedly connected to the worm 11. The inner cavity side wall of the worm 11 is fixedly connected to the connecting rod 10. The bottom of the connecting rod 10 is rotatably connected to the inner cavity bottom of the control box 4 through a rotating shaft. The top of the connecting rod 10 rotates through the control box 4. The top of the connecting rod 10 is fixedly connected to the knob 5 through a bolt.

[0022] By adopting the above technical solution, by turning the knob 5, the connecting rod 10 rotatably connected to the bottom of the inner cavity of the control box 4 and the worm 11 on its surface can be driven to rotate, thereby driving the fan-shaped worm gear 12 meshingly connected on its surface to rotate. The rotation of the fan-shaped worm gear 12 can drive the fixed rod 13 fixedly connected to the side wall of the inner cavity to rotate synchronously.

[0023] The implementation principle of an angle measuring device for engineering survey in an embodiment of the present application is as follows: the top cover 2 and the front cover 3 fixed on the measuring instrument body 1 can be made of certain high-strength engineering plastics (such as polycarbonate, polyamide, etc.) to provide sufficient strength and have certain heat insulation and waterproof properties. There is also a corresponding gap between the top cover 2 and the measuring instrument body 1, and a plurality of groups of ventilation slots 9 are provided on the top cover 2, which can provide good ventilation and heat dissipation effects while providing heat insulation. At the same time, in some rainy weather, the fixing plate 6 can be pressed to press the fixing strip 14 and the elastic sealing gasket 15 into the ventilation slot 9 to seal the ventilation slot 9 to prevent rainwater from entering the measuring instrument body 1 through the ventilation slot 9. At the same time, when sealing is not required, the two groups of handles 7 can be used to pull the entire device out of the ventilation slot 9, and the handles 7 can be hung on the hooks 8 The control box 4 is mounted on a workbench and is stored therein. By turning the knob 5, the connecting rod 10 rotatably connected to the bottom of the inner cavity of the control box 4 and the worm 11 on its surface can be driven to rotate, thereby driving the fan-shaped worm gear 12 meshingly connected to the surface to rotate. The rotation of the fan-shaped worm gear 12 can drive the fixing rod 13 fixedly connected to the side wall of the inner cavity to rotate synchronously, thereby adjusting the angle of the front cover 3, which is convenient for adjusting it according to the wind direction in rainy weather, so as to better block wind and rain, and prevent rain from directly dripping onto the eyepiece and affecting the normal measurement operation of the staff. The overall use and operation are simple, and the measuring instrument can play a role in heat insulation and heat dissipation. At the same time, in rainy weather, it can also effectively block rain to avoid affecting its normal operation and damage to related components of the measuring instrument caused by rain and high temperature, which can further improve its service life.
