Description

Technical Field

[0001] This utility model relates to the field of radar monitoring technology, specifically to a security radar monitoring device for hydropower stations. Background Technology

[0002] With increasingly stringent safety management requirements for hydropower stations, security monitoring systems are playing an increasingly important role in ensuring the safe operation of hydropower stations. Radar monitoring, as a non-contact, remote detection technology, is widely used in perimeter protection, personnel and vehicle monitoring, and other scenarios at hydropower stations.

[0003] However, most existing radar monitors can only monitor a single direction. Therefore, when applied to scenarios that require large-scale, multi-angle monitoring, such as T-junctions, it is often necessary to deploy multiple radar monitors facing different directions and then install protective covers on the outside to form a radar monitoring system to meet the needs of the scenario.

[0004] However, the concentration of multiple radar monitors inside the protective enclosure can lead to overcrowding between the devices, resulting in poor ventilation. This is especially problematic in the high-humidity environment of hydropower stations, where moisture can accumulate and affect the normal operation of the radar equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a security radar monitoring device for hydropower stations, so as to solve the technical problem in the prior art that poor ventilation and moisture accumulation are caused by the installation of multiple radar monitors inside the protective cover.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A security radar monitoring device for a hydropower station includes a mounting bracket and multiple radar monitors mounted on the mounting bracket. The radar monitors are covered by protective covers. A drive motor is mounted on the bottom surface of the inner side of the protective covers. The drive motor is positioned between the multiple radar monitors, and the working end of the drive motor is facing upward and connected to a rotating blade.

[0008] A return flow hood is provided on the outer top surface of the protective cover. The return flow hood is connected to the protective cover and is positioned directly above the rotating blade. Multiple guide pipes are provided on the peripheral wall of the return flow hood. The other end of each guide pipe is connected to the wall of the protective cover and is connected to the interior of the protective cover. Each guide pipe is positioned between adjacent radar monitors. A downward-opening vent is provided at the bottom of the protective cover.

[0009] In a preferred embodiment of this utility model, a power supply is provided inside the protective cover, and the power supply is connected to the drive motor through a wiring harness.

[0010] In a preferred embodiment of this utility model, the power supply is connected to a heating mesh, the heating mesh is connected to the power supply, the heating mesh is positioned directly above the rotating blade, and the heating mesh is connected to the bottom surface of the protective cover via a connecting bracket.

[0011] As a preferred embodiment of this utility model, a diffusion baffle is provided inside the protective cover. The diffusion baffle is mounted on the inner wall of the protective cover via mounting feet, and the diffusion baffle is positioned directly opposite the connection point between the guide pipe and the protective cover.

[0012] In a preferred embodiment of this utility model, the airflow output direction in the guide pipe is perpendicular to the length extension direction of the diffuser baffle.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention accelerates gas flow by rotating blades, thereby reducing the accumulation of internal moisture by circulating air within the protective cover. Furthermore, a guide pipe is provided to direct the accelerated airflow between adjacent radar monitors, ensuring good air circulation even in the narrow area between the radar monitors. The airflow also dries the grooves and gaps on the surface of the radar monitor housing. Through structural design, the degree of moisture accumulation inside the protective cover is significantly reduced, improving the drying effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 2 As shown, this utility model provides a security radar monitoring device for a hydropower station, including a mounting bracket 1 and multiple radar monitors 2 mounted on the mounting bracket 1. The multiple radar monitors 2 are covered by a protective cover 3. A drive motor 4 is mounted on the bottom surface inside the protective cover 3. The drive motor 4 is positioned between the multiple radar monitors 2, and the working end of the drive motor 4 is oriented upward and connected to a rotating blade 5.

[0022] A return shroud 6 is provided on the outer top surface of the protective cover 3. The return shroud 6 is connected to the protective cover 3 and is located directly above the rotating blade 5. Multiple guide pipes 7 are provided on the circumferential wall of the return shroud 6. The other end of the guide pipe 7 is connected to the wall of the protective cover 3. The guide pipe 7 is connected to the inside of the protective cover 3. The connection position of each guide pipe 7 to the protective cover 3 is located between adjacent radar monitors 2. The bottom of the protective cover 3 is provided with an air outlet 8 with an opening facing downwards.

[0023] The protective cover 3 is equipped with a power supply 9, which is connected to the drive motor 4 via a wiring harness.

[0024] The power supply 9 is connected to the heating mesh 10, which is also connected to the power supply 9. The heating mesh 10 is positioned directly above the rotating blade 5 and is connected to the bottom surface of the protective cover 3 via a connecting bracket 11. The heat flow generated by the heating mesh 10 can accelerate internal drying. The power supply to the heating mesh 10 can be selected as a periodic intermittent power supply.

[0025] In this device, the radar monitor 2 can be fixedly mounted on the wall of the protective cover cylinder 3, while the power supply 9, wiring harness, heating grid 10, and drive motor 4 can be fixedly mounted on the bottom surface of the protective cover cylinder 3. The bottom surface of the protective cover cylinder 3 is detachable, allowing the entire structure to be removed for maintenance and replacement. Specifically, the mounting bracket 1 is detachably connected to the top surface of the protective cover cylinder 3. After the entire protective cover cylinder 3 is removed, its bottom surface is then disassembled.

[0026] Furthermore, a diffusion baffle 12 is provided inside the protective cover cylinder. The diffusion baffle 12 is installed on the inner wall of the protective cover cylinder 3 via mounting feet, and the diffusion baffle 12 is positioned directly opposite the connection point between the guide pipe 7 and the protective cover cylinder 3.

[0027] The airflow output direction in the guide pipe 7 is perpendicular to the length extension direction of the diffuser baffle 12.

[0028] When the airflow perpendicular to the length extension direction of the diffuser 12 impacts the diffuser 12, it causes the airflow to diffuse, thereby allowing it to come into contact with the surface housing of the radar monitor 2 and the narrow gap between adjacent radar monitors 2 over a large area, thus enabling further heating and drying.

[0029] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
