Technical Field
[0001] This utility model relates to the technical field of waterproof devices for telemetry terminals, and more specifically to a field video telemetry terminal with multiple waterproof sealing structures. Background Technology
[0002] In today's field monitoring, video telemetry terminals play a crucial role, widely used in meteorology, hydrology, geology, and other industries. They undertake key tasks such as data acquisition, transmission, and video image acquisition. Chinese patent (CN214503933U) discloses "a highly waterproof responsive rainfall telemetry terminal." This terminal is designed with a waterproof outer shell containing an absorbent sponge. Inside the sponge is a telescopic sleeve, and the terminal body is fixed inside the sleeve. Two drainage funnels are fixed to the bottom sides of the waterproof shell. During rainy weather, water vapor or rainfall may seep into the terminal body. The absorbent sponge absorbs the moisture. When the weather clears and the telescopic sleeve is exposed to sunlight, its temperature rises, causing it to expand and compress the absorbent sponge. The moisture inside the sponge is squeezed out and discharged through the drainage funnels.
[0003] Existing simple waterproof designs are insufficient to withstand prolonged rain erosion and immersion. For example, at some field hydrological monitoring stations, telemetry terminals need to be placed near water for extended periods. To ensure normal operation, heat dissipation is necessary. However, conventional heat dissipation methods often weaken waterproof performance to some extent. For instance, if waterproofing measures are inadequate after opening heat dissipation holes, water can easily enter the equipment through these holes, causing short circuits and corrosion of electronic components, leading to equipment malfunctions, interruption of data acquisition and transmission, and severely affecting the continuity and accuracy of monitoring work.

[0019] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] Reference Figure 1 and Figure 2This utility model provides a field video telemetry terminal with a multi-layer waterproof sealing structure, including a telemetry terminal body 6, a base 1, a cover 2 fixedly connected to the top of the base 1, a cylindrical base 4 fixedly connected to the bottom of the cover 2, a funnel-shaped opening on the top of the base 1 communicating with the inside of the cylindrical base 4, a plurality of exhaust holes 5 on the side wall of the cylindrical base 4, a through hole on one side of the cover 2, and a plurality of air inlets on the other three sides of the cover 2, each of which is fixedly connected to an air inlet pipe 3. The telemetry terminal body 6 is installed on the exhaust holes 5, and the monitoring end of the telemetry terminal body 6 is fixedly installed in the through hole of the exhaust hole 5. The plurality of air inlet pipes 3 have an inclination, and the height of the end of the air inlet pipe 3 away from the cover 2 is lower than the height of the other end. The exhaust holes 5 are used to seal the air inlets on the side wall of the cover 2 and the funnel-shaped opening of the base 1.
[0021] During use, the cover 2 protects the telemetry terminal body 6 from water and rain. Through the air inlet on the side wall of the cover 2 and the exhaust port 5 on the side wall of the cylinder base 4, gas can flow inside the cover 2 and the cylinder base 4 for heat dissipation. The inclination of the air inlet pipe 3 allows rainwater entering the air inlet pipe 3 to automatically slide off, thus preventing rainwater from entering the cover 2 and affecting the telemetry terminal body 6 during the rainy season. In addition, the position of the exhaust port 5 is set lower than the height of the telemetry terminal body 6, which can prevent rainwater from entering the telemetry terminal body 6 through the exhaust port 5. In special seasons or special environments, if the entire device is submerged in water, the operation of the exhaust port 5 will close several air inlets and the funnel-shaped opening of the base 1, sealing the telemetry terminal body 6 inside the cover 2 and preventing water from entering and submerging the telemetry terminal body 6.
[0022] Reference Figure 2 , 3 The exhaust port 5 includes a fixing plate 51, which is fixedly connected to the inner wall of the cover 2. An electric cylinder 52 is installed on the top of the fixing plate 51. The output end of the electric cylinder 52 passes through the fixing plate 51 and is connected to a seat plug 53. The top of the seat plug 53 is connected to a baffle frame 54 through several connecting posts 55. The bottom shape of the seat plug 53 matches the bucket-shaped opening of the base 1. The seat plug 53 is used to block the connection between the base 1 and the cylinder seat 4. The side wall of the baffle frame 54 is in contact with the inner wall of the cover 2.
[0023] When the water level is high, the output of the electric cylinder 52 drives the seat plug 53 to move down, so that the seat plug 53 can enter the bucket-shaped opening at the top of the base 1, blocking the connection between the cover 2 and the cylinder base 4. At the same time, under the connection effect of the connecting column 55, the baffle frame 54 can move down to block the air inlet of the cover 2, thereby sealing the inside of the cover 2 and preventing water from flooding the inside of the cover 2 when the water level is too high.
[0024] Reference Figure 3A controller 56 is fixedly installed on the top of the fixing plate 51, and a liquid level sensor 57 is provided at the bottom of the seat plug 53. A wiring port extending from the top of the fixing plate 51 to the bottom is provided. The wiring terminal of the liquid level sensor 57 extends to the top of the seat plug 53. The liquid level sensor 57 is electrically connected to the controller 56 through a wire. The electric cylinder 52 is electrically connected to the controller 56 through a relay and a contactor.
[0025] The water level inside the cylinder seat 4 can be detected by setting the liquid level sensor 57. However, when the water level is detected to be too high, a signal is output to the controller 56. The controller 56 controls the electric cylinder 52 to operate, and the exhaust port 5 can then operate automatically.
[0026] Reference Figure 4 The top of the fixed plate 51 has a through hole extending to the bottom, and a knob 59 is rotatably fitted inside the hole. The top of the knob 59 has a cylindrical sliding hole, and a polygonal column 510 is slidably fitted inside the cylindrical sliding hole. A motor 58 is fixedly installed on the top of the fixed plate 51. The output end of the motor 58 passes through the fixed plate 51 and is connected to the polygonal column 510. A rotating rod 511 is fixedly connected to the bottom of the knob 59. The bottom end of the rotating rod 511 extends into the cylinder base 4 and is fixedly connected to a fan 512.
[0027] The rotation of motor 58 drives the polygonal column 510 to rotate. The shape of the polygonal column 510 drives the knob 59 to rotate. The knob 59 drives the rotating rod 511 to rotate, which in turn drives the fan 512 to rotate. This increases the air flow rate inside the cover 2 and the cylinder base 4, thus enhancing the heat dissipation effect.
[0028] Reference Figure 2 , 4 The swivel rod 511 has a slidable sleeve with a stabilizing frame 513 on its side wall, and the stabilizing frame 513 is fixedly connected to the inner wall of the cylinder seat 4.
[0029] The stability of the rotating rod 511 can be improved by setting a stabilizing bracket 513, thus preventing the rotating rod 511 from shaking.
[0030] Reference Figure 5 A movable frame plate 515 is fixedly connected to the bottom of the baffle 54. A fixed frame plate 514 is fixedly connected to the bottom of the movable frame plate 515 through a water-absorbing sponge 516. Several drip grooves are started at the top of the fixed frame plate 514. The fixed frame plate 514 is fixedly connected to the inner wall of the cover 2.
[0031] The water-absorbing sponge 516 can absorb moisture in the air, preventing some smaller moisture particles from entering the inside of the cover 2 and affecting the internal electrical components. When the exhaust port 5 operates the baffle 54 downward, it can squeeze the water-absorbing sponge 516 and squeeze out the water absorbed inside the sponge 516. The water can pass through the drip groove on the fixed frame plate 514, slide down the inner wall of the cover 2, and be discharged through the funnel-shaped opening.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
