Description

Technical Field

[0001] This invention relates to the field of protective box technology, specifically a protective box for surveying and mapping data acquisition equipment. Background Technology

[0002] Surveying data acquisition equipment is an instrument or device specifically designed for surveying operations. It is primarily used to automatically collect, record, and process geospatial data, including information on positioning, distance measurement, angle measurement, height measurement, mapping, and photogrammetry. Surveying data acquisition equipment acquires raw data through sensors or input units, converts it into digital signals for storage, transmission, and preliminary processing to support subsequent geographic information analysis. Therefore, multiple devices are required to work together to complete the data surveying operation.

[0003] The sealed structure of the protective enclosure reduces the intrusion of moisture and dust, preventing contamination of sensor interfaces or circuit boards and thus reducing data acquisition errors. In surveying scenarios, if equipment is damaged due to environmental factors, it may lead to measurement point offset or data loss. The protective enclosure maintains the stable operation of the equipment, ensuring the accuracy of the original data, especially in precision surveying (such as terrain modeling).

[0004] Existing protective cases, when protecting multiple integrated surveying data acquisition devices, suffer from heat buildup inside due to the operation of these devices. This necessitates internal ventilation and heat dissipation structures. However, the uncertainty of surveying locations, particularly when surveying buildings in construction environments, leads to dust accumulation that adheres to the ventilation vents, hindering effective heat dissipation. Furthermore, the varying sizes of different surveying data acquisition devices make it difficult for traditional protective cases to provide stable support tailored to their dimensions and structures, resulting in limited practicality. Summary of the Invention

[0005] The purpose of this invention is to provide a protective box for surveying and mapping data acquisition equipment to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: This invention provides a protective case for surveying and mapping data acquisition equipment, comprising: a base; a frame-type protective case structure mounted on top of the base; a dust removal and ventilation structure installed inside the frame-type protective case structure; and an upper cover mounted on top of the frame-type protective case structure. The dust removal and ventilation structure includes: a ventilation and dust-proof door assembly installed on the inner wall of the frame-type protective box structure; a blower cooling assembly installed at the center inside the ventilation and dust-proof door assembly; a synchronous belt connected to the outside of the blower cooling assembly via a synchronous pulley and movably disposed inside the ventilation and dust-proof door assembly; and a vibration dust removal assembly connected to the inside of the synchronous belt via a synchronous pulley and movably disposed inside the ventilation and dust-proof door assembly. The synchronous belt and the vibration dust removal assembly are each provided in pairs.

[0007] As a preferred embodiment of the present invention, the frame-type protective enclosure structure includes: a frame shell mounted on the top of the bottom seat; a hinged door mounted on the outside of the frame shell; a control terminal mounted on the top side of the frame shell and disposed on the side of the hinged door; and a first partition mounted on the inside side of the frame shell. The top of the frame shell is fitted with a top cover, and there is sufficient space between the first partition and the inner bottom of the frame shell.

[0008] As a preferred embodiment of the present invention, an embedded frame is installed inside the switch door located on one side, and a ventilation and dustproof door assembly is detachably installed inside the embedded frame.

[0009] In a preferred embodiment of the present invention, a second partition plate disposed inside the frame housing is screwed onto the side of the first partition plate. The second partition plate and the first partition plate are disposed perpendicularly to each other, and the distance between the second partition plate and the upper and lower sides of the frame housing is adjustable. The top of the second partition and the inner bottom of the frame shell are equipped with several support structures.

[0010] As a preferred embodiment of the present invention, the ventilation and dust-proof door assembly includes: a rectangular metal bracket installed inside the embedded frame body; cross-shaped plates installed on the left and right sides of the rectangular metal bracket; and a dust-proof mesh installed on the outside of the cross-shaped plates and connected to the left and right sides inside the embedded frame body. The cross-shaped plate has a blower cooling component installed at its center, and the vibration dust removal component is installed on the upper and lower sides inside the rectangular metal bracket, and cleans the dust on the surface of the dust filter.

[0011] As a preferred embodiment of the present invention, the blower cooling assembly includes: a linear drive source installed at the center of the interior of one of the cross-shaped plates; a linear rotating rod connected to the output end of the linear drive source; cooling fan blades installed at the center of the outer side of the linear rotating rod; and a guide block rotatably connected to the bottom of the linear rotating rod and installed at the center of the interior of the other cross-shaped plate. The outer side of the linear rotating rod is connected to a synchronous belt via a synchronous pulley, and the synchronous belt is located on the left and right sides of the cooling fan blades.

[0012] As a preferred embodiment of the present invention, the vibration dust removal assembly includes: a horizontal reciprocating screw connected to the inner side of the synchronous belt via a synchronous pulley and movably connected to the upper and lower sides inside the rectangular metal bracket; a horizontal slide block connected to the outer side of the horizontal reciprocating screw via ball bearings; a horizontal guide rod slidably connected to the horizontal slide block and installed on the upper and lower sides inside the rectangular metal bracket; a horizontal movable rod installed on the left and right sides of the horizontal slide block and slidably connected to the inner wall of the rectangular metal bracket; a protrusion installed on the side of the horizontal movable rod; and a rubber vibrating rod slidably connected inside the protrusion and extending to the outer side. The protrusions and rubber vibrating rods are provided in multiple quantities. The rubber vibrating rods clean the dust from the cross plate and dustproof net on the side.

[0013] As a preferred embodiment of the present invention, a first spring is installed inside the protrusion, the top of the first spring is connected to the rubber vibrating rod, and a second spring is provided on the outside of the rubber vibrating rod and connected to the top of the protrusion.

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the protective box of the surveying and mapping data acquisition equipment, when the surveying and mapping data acquisition equipment inside the protective box is used to perform data mapping on buildings and other structures in the work environment, a linear drive source can rotate the cooling fan blades to generate airflow and extract the heat located inside the protective box (generated by the operation of the surveying and mapping data acquisition equipment). This prevents heat from accumulating inside the protective box during surveying operations, ensuring the normal and safe conduct of the surveying work. Simultaneously, the force of the rotating cooling fan blades can also vibrate the surface of the dust filter screen through belt and screw drives, preventing dust from adhering to the surface of the dust filter screen and ensuring normal heat dissipation and venting from inside the protective box. 2. In the protective box for surveying and mapping data acquisition equipment, by incorporating freely movable and detachable partitions and support structures inside, the size of the surveying and mapping data acquisition equipment inside the protective box can be adjusted according to the size of the various equipment to be assembled. This satisfies the assembly and protection requirements of surveying and mapping data acquisition equipment, improving the practicality of the protective box. Simultaneously, when assembling different surveying and mapping data acquisition equipment, the space and path for heat dissipation can be rationally planned, achieving more efficient ventilation and heat dissipation. 3. In the protective box of the surveying and mapping data acquisition equipment, when the reciprocating and telescopic rubber vibrating rod removes the dust adhering to the surface of the dustproof net, the design of the spring elastic structure can reduce the magnitude of the collision force generated by the direct contact between the rubber vibrating rod and the dustproof net, avoid damage to the dustproof net due to direct collision of the rubber vibrating rod, and at the same time ensure the ability to vibrate and remove dust from the dustproof net, thereby improving the service life of the protective box structure.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] Please see Figures 1-9 The protective box for surveying and mapping data acquisition equipment includes a base 10; a frame-type protective box structure 20 installed on top of the base 10; a dust removal and ventilation structure 30 installed inside the frame-type protective box structure 20; and an upper cover 40 installed on top of the frame-type protective box structure 20. The dust removal and ventilation structure 30 includes: a ventilation and dust-proof door assembly 301 installed on the inner wall of the frame-type protective box structure 20; a blower cooling assembly 302 installed at the center inside the ventilation and dust-proof door assembly 301; a synchronous belt 303 connected to the outside of the blower cooling assembly 302 via a synchronous pulley and movably installed inside the ventilation and dust-proof door assembly 301; and a vibration dust removal assembly 304 connected to the inside of the synchronous belt 303 via a synchronous pulley and movably installed inside the ventilation and dust-proof door assembly 301. Both the synchronous belt 303 and the vibration dust removal assembly 304 are provided in two pairs.

[0020] The working principle described above is as follows: When surveying data acquisition equipment is assembled inside the frame-type protective enclosure structure 20, the frame-type protective enclosure structure 20, which allows for free disassembly and adjustment of the installation space, can accommodate and fix various surveying data acquisition devices of different sizes. The installation positions of each surveying data acquisition device are planned according to the heat generated during use, maximizing the ventilation and heat dissipation capacity inside the frame-type protective enclosure structure 20. When the surveying data acquisition equipment inside the frame-type protective enclosure structure 20 is in use, the blower cooling component 302 operates to generate suction force to expel heat from inside the frame-type protective enclosure structure 20, preventing heat accumulation inside. During the ventilation and heat dissipation process, the ventilation and dustproof door component 301 effectively prevents dust from entering the interior of the frame-type protective enclosure structure 20 by isolating dust from the working environment. When the blower cooling component 302 is in operation, it can also drive the synchronous belt 303 to operate, and drive the vibration dust removal component 304 connected to the synchronous belt 303 to operate, to remove the dust adhering to the surface of the ventilation dustproof door component 301, to prevent dust from accumulating and clogging the ventilation dustproof door component 301, and to ensure the ventilation and heat dissipation effect of the frame-type protective box structure 20.

[0021] For details, please refer to the following: Figure 3 and Figure 4 The frame-type protective enclosure structure 20 includes: a frame shell 201 installed on the top of the bottom base 10; a switch door 202 installed on the outside of the frame shell 201 via hinges; a control terminal 203 installed on the top side of the frame shell 201 and located on the side of the switch door 202; and a first partition 204 installed on the inside side of the frame shell 201, wherein a top cover 40 is installed on the top of the frame shell 201, and sufficient space is left between the first partition 204 and the inner bottom of the frame shell 201.

[0022] In this solution, an embedded frame 2021 is installed inside the switch door 202 located on one side, and a ventilation and dustproof door assembly 301 is detachably installed inside the embedded frame 2021.

[0023] In the protective box for the surveying and mapping data acquisition equipment of the present invention, the control terminal 203 allows for the conductive connection of various surveying and mapping data acquisition devices used in surveying operations, facilitating surveying operations through the control terminal 203. The first partition 204, which is detachable and installable, can be adjusted according to the size of various surveying and mapping data acquisition devices, facilitating the assembly of these devices.

[0024] For details, please refer to the following: Figure 3 and Figure 4A second partition 2041, located inside the frame housing 201, is installed on the side of the first partition 204 by screws. The second partition 2041 and the first partition 204 are arranged perpendicularly to each other. The distance between the second partition 2041 and the upper and lower sides of the frame housing 201 can be adjusted. Several support structures 2042 are installed on the top of the second partition 2041 and the inner bottom of the frame housing 201.

[0025] In the protective box for the surveying and mapping data acquisition equipment of the present invention, the second partition 2041 and the support structure 2042, which can be freely disassembled and installed, can be freely installed and adjusted according to the surveying and mapping data acquisition equipment of different sizes, making it convenient to assemble surveying and mapping data acquisition equipment of different sizes.

[0026] For details, please refer to the following: Figure 6 The ventilation and dustproof door assembly 301 includes: a rectangular metal bracket 3011 installed inside the embedded frame 2021; cross plates 3012 installed on the left and right sides of the rectangular metal bracket 3011; and dustproof nets 3013 installed on the outside of the cross plates 3012 and connected to the left and right sides inside the embedded frame 2021. A blower cooling assembly 302 is installed at the center of the cross plates 3012, and a vibration dust removal assembly 304 is installed on the upper and lower sides inside the rectangular metal bracket 3011 and cleans the dust on the surface of the dustproof net 3013.

[0027] For details, please refer to the following: Figure 6 and Figure 8 The blower cooling assembly 302 includes: a linear drive source 3021 installed at the center of the interior of a cross plate 3012; a linear rotating rod 3022 connected to the output end of the linear drive source 3021; ​​a cooling fan blade 3023 installed at the center of the outer side of the linear rotating rod 3022; and a guide block 3024 rotatably connected to the bottom of the linear rotating rod 3022 and installed at the center of the interior of another cross plate 3012. The outer side of the linear rotating rod 3022 is connected to a synchronous belt 303 via a synchronous pulley, and the synchronous belt 303 is arranged on the left and right sides of the cooling fan blade 3023.

[0028] In the protective box of the surveying and mapping data acquisition equipment of the present invention, when ventilation and heat dissipation operations are performed to dissipate the heat generated during surveying, the linear drive source 3021 is activated, driving the linear rotating rod 3022 connected to the output end of the linear drive source 3021 to rotate, which in turn drives the cooling fan blades 3023 mounted on the outside of the linear rotating rod 3022 to rotate, generating a suction force to dissipate the heat. While the linear rotating rod 3022 is rotating, the synchronous belt 303 connected to its outer side via a synchronous pulley will also operate.

[0029] For details, please refer to the following: Figure 7 , Figure 8 and Figure 9The vibration dust removal assembly 304 includes: a horizontal reciprocating screw 3041 connected to the inside of the synchronous belt 303 via a synchronous pulley and movably connected to the upper and lower sides inside the rectangular metal bracket 3011; a horizontal slide block 3042 connected to the outside of the horizontal reciprocating screw 3041 via ball bearings; a horizontal guide rod 3043 slidably connected to the horizontal slide block 3042 and installed on the upper and lower sides inside the rectangular metal bracket 3011; a horizontal movable rod 3044 installed on the left and right sides of the horizontal slide block 3042 and slidably connected to the inner wall of the rectangular metal bracket 3011; a protrusion 3045 installed on the side of the horizontal movable rod 3044; and a rubber vibrating rod 3046 slidably connected inside the protrusion 3045 and extending to the outside. Multiple protrusions 3045 and rubber vibrating rods 3046 are provided. The rubber vibrating rods 3046 clean the dust from the cross plate 3012 and dust filter 3013 located on the side.

[0030] In this design, a first spring 30451 is installed inside the protrusion 3045, a rubber vibrating rod 3046 is connected to the top of the first spring 30451, and a second spring 30452 connected to the top of the protrusion 3045 is provided on the outside of the rubber vibrating rod 3046.

[0031] In the protective box of the surveying and mapping data acquisition equipment of the present invention, when the synchronous belt 303 is operating, the horizontal reciprocating screw 3041 connected to the inner side of the belt via the synchronous pulley rotates, driving the horizontal slide 3042 connected to the outer side of the horizontal reciprocating screw 3041 via ball bearings to extend and retract outside the horizontal guide rod 3043. When the horizontal slide 3042 extends and retracts horizontally, it drives the horizontal movable rod 3044 installed on the outer side of the horizontal slide 3042 to extend and retract (reciprocate) inside the rectangular metal bracket 3011.

[0032] At this time, when the horizontal movable rod 3044 is moving in extension and retraction, the rubber vibrating rod 3046 connected to its side via the protrusion 3045 moves, causing the cross plate 3012 and the dust screen 3013 that are in contact with the side of the rubber vibrating rod 3046 to vibrate inside the rectangular metal bracket 3011, thereby removing the dust adhering to the dust screen 3013 through vibration.

[0033] When the rubber vibrating rod 3046 comes into contact with the dust filter 3013, it will first compress the first spring 30451 and the second spring 30452. At this time, the elasticity of the first spring 30451 and the second spring 30452 will reduce the damage to the dust filter 3013 caused by direct collision, and improve the effect of removing dust from the surface of the dust filter 3013 through elastic movement.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
