DETAILED DESCRIPTION

[0033] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0034] Reference Figure 1-3 The embodiment of the present invention provides an outdoor communication device, which may include a protective compartment 1, a bottom plate 2, a cabinet 3, an electric lifting assembly 4, a side compartment 5, a floating block 6, and a control switch 7, wherein:

[0035] The bottom plate 2 is horizontally placed (horizontally placed means that the end face of the bottom plate 2 is parallel to the horizontal plane) on the inner bottom wall of the protective bin 1, and is slidably connected to the side wall of the protective bin 1. The bottom plate 2 is horizontally placed to form a mounting surface, and the cabinet 3 is fixed on the mounting surface of the bottom plate 2. The electric lifting assembly 4 is fixed to the inner top wall of the protective bin 1, and the output shaft of the electric lifting assembly 4 is vertically arranged and connected to the bottom plate 2. Among them, the electric lifting assembly 4 drives the cabinet 3 to perform lifting movement when working. For example, the electric lifting assembly 4 provides a power for the bottom plate 2 to perform lifting movement in the vertical direction, thereby driving the cabinet 3 located on the bottom plate 2 to perform lifting movement.

[0036] The side bin 5 is arranged side by side with the protective bin 1, and the bottom of the side bin 5 is flush with the bottom of the protective bin 1. The side bin 5 can be fixed to the protective bin 1 by welding, threaded connection, etc., wherein a plurality of water holes 501 are provided on the inner wall of the side bin 5. Those skilled in the art can determine the number of water holes 501 according to actual needs. For example, the number of water holes 501 can be 2, 3, 4, etc., which are not limited here. The floating block 6 is located above the water hole 501 and is slidably connected to the inner wall of the side bin 5. The floating block 6 is made of a material with a relatively low density. The control switch 7 is a pressure-touch switch, which can be fixed to the inner top wall of the side bin 5 by means of screws, bolts, etc., and is electrically connected to the electric lifting assembly 4. The floating block 6 slides upward along the inner wall of the side compartment 5 under the action of buoyancy to press the control switch 7, and the switch state of the control switch 7 is changed by the pressing force generated by the floating block 6 on the control switch 7, so that the electric lifting assembly 4 lifts the cabinet 3 under the control of the control switch 7. This prevents the ground water from penetrating into the cabinet 3 when the depth is too high and causing a short circuit fault, thereby improving the operation stability of the communication cabinet 3.

[0037] The above-mentioned sliding connection can be achieved by providing sliding grooves on the inner wall of the protective bin 1 and the inner wall of the side bin 5, and providing sliding blocks that match the shape of the sliding grooves on the side of the bottom plate 2 and the side of the floating block 6.

[0038] An optional embodiment of the invention, the electric lifting assembly 4 may include a rotational motion output device 401 and a threaded rod 402. The rotational motion output device 401 is installed on the inner top wall of the protective bin 1, and the output device of the rotational motion output device 401 is vertically downward, and the threaded rod 402 is coaxially fixed with the output shaft of the rotational motion output device 401. Among them, the rotational motion output device 401 can be a servo motor, etc., and the output shaft of the rotational output device and the threaded rod 402 can be fixed by a coupling. The threaded rod 402 is threadedly connected to the base plate 2, and passes through the base plate 2 to be rotatably connected to the inner bottom wall of the protective bin 1. Among them, a bearing can be installed on the inner bottom wall of the protective bin 1, so that the threaded rod 402 can be installed on the bearing to achieve a rotational connection.

[0039] The device may further include a controller, and the control switch 7 and the rotational motion output device 401 are respectively coupled to the controller, wherein the controller is used to control the forward and reverse rotation of the rotational motion output device 401. For example, when the control switch 7 is pressed and closed by the floating block 6, the controller controls the rotational motion output device 401 to rotate forward to lift the cabinet 3. When the control switch 7 is not pressed and automatically disconnected by the floating block 6, the controller controls the rotational motion output device 401 to reverse to lower the cabinet 3.

[0040] In another example, in order to improve the stability of the lifting cabinet 3 and the service life of the rotational motion output device 401, two electric lifting components 4 can be used, that is, the lifting of the cabinet 3 is achieved through two rotational motion output devices 401.

[0041] An optional embodiment of the invention, considering that the water level in the side compartment 5 rises and triggers the control switch 7, it means that the outdoor precipitation is large and is likely to reach the height of the bottom of the cabinet 3 in the protective compartment 1 in a short time. The water that has penetrated into the protective compartment 1 may continue to penetrate into the cabinet 3 as the water level rises, causing a short circuit fault. Therefore, referring to Figure 1 As shown, the installation height H1 of the control switch 7 is equal to the installation height H2 of the bottom of the cabinet 3. After the control switch 7 is triggered, it means that the ground water level is about to reach the installation height H2 of the bottom of the cabinet 3. At this time, it is determined as a water level alarm, and the cabinet 3 needs to be lifted. If it is not lifted, there may be a risk of short circuit failure in the cabinet 3, thereby affecting the communication stability.

[0042] An optional embodiment of the invention, referring to Figure 2As shown, the several water holes 501 are evenly spaced in the vertical direction. The interval between two adjacent water holes 501 should not be too large, such as 0.5 cm as an interval. Thus, the water level in the side bin 5 can maintain good consistency with the external water level through the several water holes 501. Improve the accuracy of outdoor water level monitoring. In one example, the cross-sectional shape of the water hole 501 is rectangular, so that when the ground water level rises, it can flow into the side bin 5 through the water hole 501 in time. When the ground water level drops, the water in the side bin 5 can also flow out through the water hole 501 in time. The water inlet and outlet of each water hole 501 can be consistent, which can improve the accuracy of the water level alarm of the side bin 5.

[0043] In an optional embodiment of the invention, the cross-sectional area of ​​the side bin 5 in the horizontal plane direction is equal to the preset cross-sectional area, wherein the preset cross-sectional area is determined according to the unit water inflow L of the plurality of water-permeable holes 501. The unit water inflow refers to the amount of water that passes through the plurality of water-permeable holes 501 within 1S. For example, when the number of water-permeable holes 501 is 3 and the unit water inflow L of the 3 water-permeable holes 501 is 160ML / S, the calculation formula of the preset cross-sectional area S is:

[0044] S=L*T / H3 Formula (1)

[0045] In the above formula (1), T is the preset response time, H3 is the height from the highest water-permeable hole 501 to the bottom of the side bin 5, Figure 2 As shown. For example, when the preset response time is 2S and H3 is 8cm, the corresponding preset cross-sectional area is 40cm2; technicians in this field can determine the length and width of the side bin 5 in the horizontal plane according to the preset cross-sectional area, which is not limited here. This can avoid the situation where the water level rises faster in a heavy rainfall environment, such as a heavy rainstorm, the water level in the side bin 5 rises slower, and the cabinet 3 is not lifted in time, causing a short circuit fault, thereby improving the timeliness of the water level alarm in the side bin 5.

[0046] An optional embodiment of the invention, referring to Figure 1As shown, the side of the protective chamber 1 is also provided with a plurality of heat dissipation holes 8, and the device also includes a heat dissipation component 9 fixed to the top of the protective chamber 1, and the heat dissipation component 9 may include a ventilation window 901 and a heat dissipation fan 902, wherein the ventilation window 901 is embedded in the top of the protective chamber 1 to connect the inside and outside of the protective chamber 1. The heat dissipation fan 902 is located in the ventilation window 901, and is used to guide the fresh air flowing into the protective chamber 1 from the heat dissipation hole 8 to the outside of the protective chamber 1. Among them, the fresh air refers to the air outside the protective chamber 1. The inner and outer sides of the ventilation window 901 are both provided with a second filter screen, and the two second filters wrap the heat dissipation fan 902. In addition, a protective top plate 11 is also provided on the outer top of the protective chamber 1, wherein the cross-sectional shape of the protective top plate 11 is V-shaped, and the opening of the protective top plate 11 is arranged toward the protective chamber 1, thereby, the top of the protective top plate 11 can form a water guide surface to prevent rainwater from entering the protective chamber 1 through the heat dissipation component 9.

[0047] In an optional embodiment of the invention, the plurality of heat dissipation holes 8 are provided at equal intervals in the vertical direction, and the opening height of each heat dissipation hole 8 located inside the protective chamber 1 is greater than the opening height located outside the protective chamber 1. In other words, the heat dissipation holes 8 are distributed in an inclined shape with the inner part higher and the outer part lower. Since the heat dissipation fan 902 is arranged at the top of the protective chamber 1, it can change the flow direction of fresh air through the inclined heat dissipation holes 8, thereby improving the heat dissipation efficiency of the heat dissipation fan 902.

[0048] An optional embodiment of the invention, referring to Figure 1 and Figure 3 As shown, a first filter 10 is also fixed to the side of the protective compartment 1, and the first filter 10 wraps a plurality of heat dissipation holes 8 to filter the fresh air. In another example, a plurality of heat dissipation holes 8 can be respectively opened on both sides of the protective compartment 1, and two first filters 10 can be provided, thereby increasing the amount of fresh air intake. Considering that the cabinet body of the cabinet 3 is usually an integrated structure, the first location where water seepage occurs is the door gap of the cabinet door of the cabinet 3. Therefore, the cooling fan 902 is projected at the bottom of the protective compartment 1 in front of the cabinet door of the cabinet 3. When water accidentally seeps into the protective compartment 1, the air-cooling effect of the cooling fan 902 can speed up the circulation of fresh air, increase the drying speed of the seepage water in front of the cabinet door of the cabinet 3, and further optimize the product performance of the device.

[0049] In summary, an embodiment of the present invention discloses an outdoor communication device, which includes a protective bin 1, a bottom plate 2, a cabinet 3, an electric lifting assembly 4, a side bin 5, a floating block 6, and a control switch 7. The bottom plate 2 is horizontally placed on the inner bottom wall of the protective bin 1 and is slidably connected to the side wall of the protective bin 1. The cabinet 3 is fixed on the bottom plate 2. The electric lifting assembly 4 is fixed to the inner top wall of the protective bin 1, and the output shaft of the electric lifting assembly 4 is vertically arranged and connected to the bottom plate 2. When the electric lifting assembly 4 is working, it drives the cabinet 3 to move up and down. The side bin 5 is arranged side by side with the protective bin 1, and the bottom of the side bin 5 is flush with the bottom of the protective bin 1, wherein a plurality of water-permeable holes 501 are opened on the inner side wall of the side bin 5. The floating block 6 is located above the water-permeable hole 501 and is slidably connected to the inner side wall of the side bin 5. The control switch 7 is fixed on the inner top wall of the side compartment 5 and is electrically connected to the electric lifting assembly 4. The floating block 6 slides upward along the inner wall of the side compartment 5 under the action of buoyancy to press the control switch 7, so that the electric lifting assembly 4 lifts the cabinet 3 under the control of the control switch 7. This prevents the ground water from penetrating into the cabinet 3 when the depth is too high and causing a short circuit fault, thereby improving the operation stability of the communication cabinet 3.
