Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tunnel inspection equipment, and in particular to a tunnel inspection trolley. Background Technology
[0002] In summer, the temperature inside the tunnel is low, while the temperature outside the tunnel is high. When the inspection vehicle enters the tunnel, the water vapor in the air inside the vehicle will liquefy due to the large temperature difference between the inside and outside and form water droplets that adhere to the inner wall of the casing. In addition, when the water droplets on the inner wall of the tunnel fall on the casing, they may enter the casing through the gaps. When the water falls on the electronic components inside the casing, it can easily cause the components to short circuit. Utility Model Content
[0003] The main purpose of this utility model is to propose a tunnel inspection trolley, which aims to solve the problem that existing inspection vehicles are prone to short circuits due to condensation on internal components during inspection.
[0004] To achieve the above objectives, this utility model proposes a tunnel inspection trolley, comprising a movable base, a water guiding structure, and a base plate. The base plate has an installation area for mounting various electronic components. The movable base is provided with a drainage structure. The base plate is disposed on the movable base. The water guiding structure is located directly above the installation area of the base plate. The water guiding structure has a water guiding surface for guiding the flow of condensate, and the outlet of the water guiding structure is located above the drainage structure, so that condensate can flow from the water guiding structure into the drainage structure.
[0005] According to some embodiments of the present invention, the drainage structure includes multiple drainage channels that can communicate with the outside world, and the multiple drainage channels are respectively opened around the top surface of the movable base.
[0006] According to some embodiments of the present invention, the substrate is located above the movable base.
[0007] According to some embodiments of the present invention, a guide structure is further provided on the movable base, the extension direction of the guide structure is perpendicular to the top surface of the movable base, and the base plate is movably mounted on the guide structure.
[0008] According to some embodiments of the present invention, the substrate also has an opening area for condensate on the substrate to flow out from the opening area.
[0009] According to some embodiments of the present invention, the water guiding structure includes a first water guiding plate and a second water guiding plate, wherein at least one water outlet end of the first water guiding plate is located above the corresponding drainage trough, and at least one water outlet end of the second water guiding plate is located above the other corresponding drainage trough.
[0010] According to some embodiments of the present invention, both the first water guide plate and the second water guide plate have two water outlets, and the water outlets of the first water guide plate and the second water guide plate that are close to each other are located above the opening area.
[0011] According to some embodiments of the present invention, the first water guide plate is higher than the second water guide plate, and the water outlet end of the first water guide plate near the second water guide plate is located above the second water guide plate.
[0012] According to some embodiments of the present invention, both the first water guide plate and the second water guide plate are arranged in an arc shape.
[0013] According to some embodiments of the present invention, a third water guide plate is further included in an arc shape. The third water guide plate is located directly below the opening area of the substrate, and the two water outlet ends of the third water guide plate are respectively located above the two corresponding drainage grooves.
[0014] This utility model has at least the following beneficial effects:
[0015] In this invention, the movable base is equipped with a drainage structure. When condensate adhering to the inner wall of the trolley housing and water entering the housing through gaps falls onto the water-guiding structure, it flows towards the outlet under the guidance of the water-guiding surface of the structure. Since the outlet is located above the drainage structure, the condensate flows into the drainage structure under the action of gravity and is eventually discharged from the tunnel inspection trolley. By setting the water-guiding structure above the mounting area where various electronic components are installed, the falling condensate is blocked and guided out of the tunnel inspection trolley, preventing condensate from falling on the electronic components and causing short circuits. The tunnel inspection trolley provided by this invention solves the problem of short circuits caused by condensate affecting internal components during inspections in existing inspection vehicles.

[0025] This utility model provides a tunnel inspection trolley. Figures 1 to 3 This is a specific embodiment of the present utility model.
[0026] like Figures 1 to 2As shown, this utility model embodiment provides a tunnel inspection trolley 100, including a movable base 1, a water guiding structure 2, and a base plate 3. The base plate 3 has an installation area 31 for mounting various electronic components. The movable base 1 is provided with a drainage structure 11. The base plate 3 is disposed on the movable base 1. The water guiding structure 2 is located directly above the installation area 31 of the base plate 3. The water guiding structure 2 has a water guiding surface for guiding the flow of condensate, and the outlet of the water guiding structure 2 is located above the drainage structure 11 so that condensate can flow from the water guiding structure 2 into the drainage structure 11.
[0027] In this invention, the movable base 1 is equipped with a drainage structure 11. When condensate adhering to the inner wall of the trolley housing and water entering the housing from the gaps fall onto the water guiding structure 2, it can flow to the outlet under the guidance of the water guiding surface of the water guiding structure 2. Since the outlet is located above the drainage structure 11, the condensate flows into the drainage structure 11 under the action of gravity and is finally discharged from the tunnel inspection trolley 100. By setting the water guiding structure 2 above the mounting area 31 where various electronic components are installed, the falling condensate is blocked and guided to drain from the tunnel inspection trolley 100, preventing condensate from falling on the electronic components and causing short circuits. The tunnel inspection trolley 100 provided by this invention solves the problem that existing inspection vehicles are prone to short circuits due to condensate affecting internal components during inspection.
[0028] The specific structure of the drainage structure 11 is not limited, as long as it ensures that the drainage structure 11 can discharge condensate water from the tunnel inspection vehicle 100. For example, in some embodiments, such as... Figure 1 As shown, the drainage structure 11 includes multiple drainage channels 111 that can communicate with the outside. The multiple drainage channels 111 are respectively opened around the top surface of the movable base 1. Since most of the condensate will collect on the bottom movable base 1 under the action of gravity, by opening multiple drainage channels 111 around the top surface of the movable base 1, the condensate at various locations on the movable base 1 can be discharged from the drainage channels 111.
[0029] In heavy rain, deep water may accumulate inside the tunnel. To prevent water from seeping into the housing of the tunnel inspection trolley 100 during inspections and submerging the electronic components inside, causing short circuits, in some embodiments, such as... Figure 1 and Figure 2 As shown, the substrate 3 is located above the movable base 1. With this configuration, by raising the position of the substrate 3, even if water from the tunnel seeps into the housing and floods the movable base 1, it will not immediately flood the substrate 3, and the components mounted on the substrate 3 will not be affected or short-circuited in a short period of time.
[0030] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the tunnel inspection trolley 100 also includes a guide structure 4 disposed on the movable base 1. The extension direction of the guide structure 4 is perpendicular to the top surface of the movable base 1, and the base plate 3 is movably mounted on the guide structure 4. Specifically, the guide structure 4 includes four guide rods, and the base plate 3 has four mounting holes. Each guide rod passes through the corresponding mounting hole, allowing the base plate 3 to move on the guide structure 4. At the same time, the guide rods and the mounting holes are fixed by a locking mechanism, so that the base plate 3 is positioned on the guide structure 4 after the height is adjusted.
[0031] Since some water vapor inside the casing may liquefy and form water droplets that adhere to the substrate 3, in order to prevent this condensate from affecting the components, such as... Figure 1 As shown, the substrate 3 also has an opening area 32 for condensate on the substrate 3 to flow out through the opening area 32. This arrangement allows condensate adhering to the substrate 3 to drain out through the opening area 32 by creating an opening in the substrate 3.
[0032] For heat dissipation and practical wiring considerations, not all electronic components are concentrated in one area of the substrate 3; they are generally distributed. If a single water-guiding component were used, it would cover the entire substrate 3 to prevent condensation from falling onto the components, which would be too costly and require too much space. Therefore, in some embodiments, such as... Figure 1 and Figure 2 As shown, the water guiding structure 2 includes a first water guiding plate 21 and a second water guiding plate 22. At least one water outlet of the first water guiding plate 21 is located above the corresponding drainage groove 111, and at least one water outlet of the second water guiding plate 22 is located above the other corresponding drainage groove 111. By setting multiple water guiding plates, the position of each water guiding plate can be adjusted according to the installation position of the components. Since the top surface of the movable base 1 is provided with drainage grooves 111 around its perimeter, even with four water guiding plates, the condensate on each water guiding plate can flow into the corresponding drainage groove 111.
[0033] The specific shapes of the first water guide plate 21 and the second water guide plate 22 are not limited, as long as both the first water guide plate 21 and the second water guide plate 22 have at least one outlet for discharging condensate. For example, in some embodiments, such as... Figure 1 and Figure 2As shown, both the first water guide plate 21 and the second water guide plate 22 have two water outlets, and the water outlets of the first water guide plate 21 and the second water guide plate 22 that are close to each other are located above the opening area 32. With this configuration, the water outlet of the first water guide plate 21 that is away from the second water guide plate 22 is located above the corresponding drainage groove 111, and the water outlet that is close to the second water guide plate 22 is located above the opening area 32. Similarly, the second water guide plate 22 is configured similarly. The condensate on the first water guide plate 21 and the second water guide plate 22 is discharged in two separate parts, improving drainage efficiency.
[0034] Specifically, in some embodiments, such as Figure 1 and Figure 2 As shown, both the first water guide plate 21 and the second water guide plate 22 are arc-shaped. With this configuration, the two ends of the arc-shaped water guide plate are the two water outlets, allowing condensate to flow along the arc surface to the water outlets.
[0035] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the first water guide plate 21 is higher than the second water guide plate 22, and the water outlet end of the first water guide plate 21 near the second water guide plate 22 is located above the second water guide plate 22. Since the amount of condensate in the housing is relatively small, the water outlet end of the first water guide plate 21 being located above the second water guide plate 22 can collect some of the condensate on the first water guide plate 21 and discharge it together with the second water guide plate 22, avoiding insufficient condensate and resulting in a slow flow rate of condensate. At the same time, by placing the first water guide plate 21 above the second water guide plate 22, the condensate in the substrate 3 area can be guided by each water guide plate, preventing a small amount of condensate from splashing onto the components.
[0036] Since the condensate flows into the opening area 32 and then falls onto the top surface of the movable base 1 before flowing to the drainage channels 111 for discharge, this process is inefficient. Therefore, in some embodiments, such as... Figures 1 to 3 As shown, the tunnel inspection trolley 100 also includes a third water guide plate 5 arranged in an arc shape. The third water guide plate 5 is located directly below the opening area 32 of the base plate 3, and the two water outlets of the third water guide plate 5 are respectively located above the two corresponding drainage grooves 111. With this arrangement, the condensate flowing into the opening area 32 will fall onto the third water guide plate 5 and flow out from the two drainage grooves 111 under the guidance of the second water guide plate 22. This avoids the condensate from splashing onto the movable base 1 from the opening area 32, and improves the drainage efficiency by guiding it through the arc-shaped third water guide plate 5.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
