Sand-collecting sliding sleeve 6 is fixedly installed with fixed pole 7, and on the fixed pole 7, a plurality of collection baffles 701 are evenly installed, and when wind-sand and rain and snow scrapers collect on the baffle 701, the collection baffle 701 is opposite to wind-sand and baffle plate 701. Rain and snow are blocked, and wind and sand and rain and snow are allowed to fall down, increasing the speed of accumulating dust, rainwater and snow accumulation in the collection tank 601, so that a large amount of dust, dust, Rainwater and accumulated snow make sand collection slide cover 6 slide downwards.

A sliding arc plate 10 and a discharge limiting plate 11 are slidably installed in the collection tank 601, a first discharge port 602 and a second discharge port 603 are arranged on the side wall of the collection tank 601, and the top of the discharge limit plate 11 is A push type vibrating motor 12 and a first buffer spring 111 are fixedly installed on the surface, and the top of the first buffer spring 111 is fixedly connected with the bottom surface of the sliding arc plate 10, and the bottom surface of the discharge limit plate 11 is fixedly installed with a second buffer spring 112, The bottom of the second buffer spring 112 is fixedly connected to the bottom surface of the collecting tank 601, the first discharge port 602 is located above the second discharge port 603, and the position height of the discharge limiting plate 11 is between the first discharge port 602 and the first discharge port 603.

The gravity of the sliding arc plate 10 itself will compress the first buffer spring 111, and the gravity of the sliding arc plate 10, the first buffer spring 111, the second buffer spring 112 and the discharge limit plate 11 will then compress the second buffer spring 112 , the compressed first buffer spring 111 and the second buffer spring 112 have the same length.

When it rains and snows, rain and snow will accumulate on the sliding arc plate 10, so that the first buffer spring 111 and the second buffer spring 112 are compressed, so that the top surface of the sliding arc plate 10 is successively lower than the first discharge port 602 and the second The discharge port 603 allows rainwater and snow melted from snow to flow out from the first discharge port 602 and the second discharge port 603 .

When scraping a sandstorm, sand and soil will accumulate on the sliding arc plate 10, because the sand and soil are not liquid, even if the top surface of the sliding arc plate 10 is lower than the first discharge opening 602, the sand and soil will not flow from the first discharge opening 602 and the second discharge opening 602. When the first buffer spring 111 is compressed, the distance between the sliding arc plate 10 and the discharge limit plate 11 is shortened, and the bottom surface of the sliding arc plate 10 will be offset against the pressing vibration motor 12, so that the pressing vibration motor 12 triggers the start, and the pressing vibration motor 12 drives the sliding arc plate 10 to vibrate, because the top surface of the sliding arc plate 10 is a raised arc surface, and the sand and soil will vibrate and move towards the edge of the sliding arc plate 10, and finally move from the first row Material outlet 602 and the second discharge port 603 are discharged.

Receive and reflect the wireless network signal, improve the quality of receiving the wireless network signal of the receiver body 1, and the hemispherical shell can be rotated conveniently.

The shell part of outer protective shell 14 and inner protective shell 13 is carbon fiber shell, improves the protective strength of outer protective shell 14 and inner protective shell 13 by carbon fiber shell, under the impact of wind and sand, outer protective shell 14 and inner protective shell 13 are also difficult to If damaged, the curved surface inside the inner protective shell 13 is an aluminum plate, which can reflect the wireless network signal and enhance the receiving quality of the wireless network signal of the receiver body 1 .

The inner protective shell 13 is connected with the fixed frame 3 in rotation, and the two ends of the inner protective shell 13 are fixedly equipped with threaded rods 131, and the threaded rods 131 are threaded with threaded caps 132, and the threaded caps 132 are offset against the fixed frame 3, because the wireless network signal transmits The position of the source is different, and the angle orientation of the inner protective shell 13 also needs to be changed, and the inner protective shell 13 and the fixed frame 3 are relatively fixed by the threaded cap 132 and the threaded rod 131, so that they cannot be rotated relative to each other.

The inner protective shell 13 is fixed with a rotation limiting block 133, and the outer protective shell 14 is provided with two rotation limiting slots 142 that match the inner protective shell 13, and the rotation limiting block 133 snaps into the rotation limiting slot 142. , when the outer protective shell 14 is rotated to close, it can only be rotated one hundred and eighty degrees to prevent the outer protective shell 14 from turning too far, the inner protective shell 13 and the outer protective shell 14 cannot be airtight, and a gap occurs. When the outer protective shell 14 is rotated and opened, The rotation limit block 133 also limits the outer protective shell 14 to prevent the outer protective shell 14 from rotating too far, and blocks the inner protective shell 13 and the receiver body 1, thereby affecting the reception of wireless network signals.

Both the inner protective shell 13 and the outer protective shell 14 are rotatably connected with the clamping rod 15, the inner protective shell 13 and the outer protective shell 14 are provided with notches matching the clamping rod 15, and the clamping rod 15 is provided with a receiving groove 152, when the inner protective shell 13 and the outer protective shell 14 rotate, the clamping rod 15 will not affect it, and at the same time, the network cable or power cord of the receiver body 1 is stored in the clamping rod 15, and it will not The rotation of the inner protective shell 13 and the outer protective shell 14 is obstructed.

The present invention installs and adjusts the orientation of the control fixing frame 3 and the inner protective shell 13 according to the orientation of the wireless network signal transmission source. At this time, the orientation of the outer protective shell 14 is also fixed, and water is supplied to the water storage tank 501 and the control sleeve shaft 16. , so that the bottom surface of the sliding gear rod 17 is in contact with the water surface in the control sleeve shaft 16, and the sand collection sliding sleeve 6 is installed on the water storage base 5, so that the bottom surface of the lower pressure column 8 is in contact with the liquid surface in the water storage tank 501. At this time, the balance spring 9 The elastic force provided by the compression and the sand collection sliding sleeve 6, the fixed pole 7, the collection baffle 701, the sliding arc plate 10, the discharge limit plate 11, the first buffer spring 111, the second buffer spring 112, the second buffer spring 112. The gravity balance of the pressing vibration motor 12.

According to the situation, it can be divided into four situations: small amount of rainfall and snowfall, small amount of sandstorm, heavy rainfall and snowfall, and large amount of sandstorm.

When the rain and snow under are small, the receiver instrument body 1 does not need to be protected, and the rain and snow will accumulate on the sliding arc plate 10, so that the first buffer spring 111 and the second buffer spring 112 are compressed, so that the sliding arc plate 10 The top surface of the top surface is lower than the first discharge opening 602, so that rainwater and snow melted snow water flow out from the first discharge opening 602. At this time, the increased weight of the rainwater in the collection tank 601 is small, and the increased gravity is not enough Allow the balance spring 9 to compress and deform, so the pressing column 8 will not be pressed down, the water in the water storage tank 501 will not be pressed into the control sleeve shaft 16, and the sliding gear rod 17 will not move up. 14 will not turn.

When the blown sand is small, the sand will accumulate on the sliding arc plate 10, because the sand is not liquid, even if the top surface of the sliding arc plate 10 is lower than the first discharge port 602, the sand will not flow from the first discharge port 602. 602, and because the elastic coefficient of the first buffer spring 111 is smaller than the elastic coefficient of the second buffer spring 112, according to Hooke's law, the amount of deformation of the spring is proportional to the applied force and inversely proportional to the spring constant, so the increase of sand and soil The pressure of gravity on the first buffer spring 111 and the second buffer spring 112 is the same, so the compression deformation of the first buffer spring 111 will be greater than the compression deformation of the second buffer spring 112, when the first buffer spring 111 is compressed, the sliding arc plate The distance between 10 and the discharge limit plate 11 is shortened, and the bottom surface of the sliding arc plate 10 will be offset against the pressing vibration motor 12, so that the pressing vibration motor 12 is triggered to start, and the pressing vibration motor 12 drives the sliding arc plate 10 to vibrate, because the sliding The top surface of the arc plate 10 is a raised arc surface, and the sand will vibrate and move towards the edge of the sliding arc plate 10, and finally be discharged from the first discharge port 602. At this time, the increased gravity is not enough to allow the balance spring 9 to move. Compression deformation, so the pressing column 8 will not be pressed down, the water in the water storage tank 501 will not be pressed into the control sleeve shaft 16, the sliding gear rod 17 will not move up, and the outer protective shell 14 will not rotate .

When the current rain and snow are very big, when the speed accumulated on the sliding arc plate 10 is greater than the discharge speed of the first discharge port 602, the accumulated water or snow in the collection tank 601 will continue to increase, and the gravity will also continue to increase. Both a buffer spring 111 and a second buffer spring 112 are compressed to the lowest point, so that the top surface of the sliding arc plate 10 is lower than the second discharge port 603, and the aperture of the second discharge port 603 is larger than that of the first discharge port 602. If the accumulated water is greater than the displacement of the first discharge port 602, but less than the displacement of the first discharge port 602 plus the second discharge port 603, the sliding arc plate 10 will eventually meet the second discharge port 603. Carry out partial blockage, reduce the displacement of the second discharge port 603, make the accumulated water velocity equal to the displacement of the first discharge port 602 plus the second discharge port 603, at this time, the overall weight of the sand collection sliding sleeve 6 has reached balance Due to the compression deformation of the spring 9, the sand-collecting sliding sleeve 6 and the pressing column 8 will be pressed down, so that the water in the water storage tank 501 is pressed into the control sleeve shaft 16, and the water in the control sleeve shaft 16 will push the sliding gear rod 17 moves up, and the sliding gear rod 17 will drive the control gear 141 to rotate, allowing the outer protective shell 14 to rotate 180 degrees, and finally the rotation limiting block 133 is snapped into the rotation limiting groove 142, allowing the outer protective shell 14 to stop Rotate, at this time the resistance provided by the inner protective shell 13 and the rotation limit block 133 plus the gravity of the sliding gear rod 17 and the thrust of the water in the control sleeve shaft 16 reach a balance, and the outer protective shell 14 rotates to protect the receiver instrument body 1 , to prevent heavy rain and snow from impacting the receiver body 1 and causing damage to the receiver body 1. When the rainfall decreases and the water accumulation speed is lower than the drainage speed of the first discharge port 602 plus the second discharge port 603, slide the arc plate 10 It will gradually move up, and finally the accumulated water will be completely discharged, and the gravity of the sand-collecting sliding sleeve 6 and the internal mechanism will decrease. Under the thrust of the water pressure and the elastic force of the balance spring 9, the sand-collecting sliding sleeve 6 will move up again, and the sliding teeth will Bar 17 also can slide down, and control gear 141 is reversely rotated, and outer protection shell 14 reversely rotates 180 degrees, and rotates again to open.

When the blown sand is very large, the sand will be discharged from the second discharge port 603. When the discharge speed is less than or equal to the accumulated speed, the gravity of the sand-collecting sliding sleeve 6 and the internal mechanism will increase. At this time, the sand-collecting slide When the overall weight of the sleeve 6 has reached the compression deformation of the balance spring 9, the sand-collecting sliding sleeve 6 and the lower pressure column 8 will be pressed down, so that the water in the water storage tank 501 is pressed into the control sleeve shaft 16, and the control sleeve shaft 16 The water will push the sliding gear bar 17 to move up, and the sliding gear bar 17 will drive the control gear 141 to rotate, so that the outer protective shell 14 will rotate by 180 degrees, and finally the rotation limiting block 133 will snap into the rotation limiting groove 142 Inside, let the outer protective shell 14 stop rotating, now the resistance provided by the inner protective shell 13 and the rotation limit block 133 plus the gravity of the sliding gear rod 17 and the thrust of the water in the control sleeve shaft 16 reach a balance, and the outer protective shell 14 rotates Protect the receiver instrument body 1 to prevent wind and sand from damaging the receiver instrument body 1. After the wind and sand become smaller, the sand and soil will still be discharged from the first discharge port 602 and the second discharge port 603, and the discharge speed is greater than Accumulated speed, the sliding arc plate 10 will gradually move up, and finally the sand and soil will be completely discharged, the gravity of the sand-collecting sliding sleeve 6 and the internal mechanism will decrease, and under the thrust of the water pressure and the elastic force of the balance spring 9, the sand-collecting sliding sleeve will 6. Move up again, and the sliding gear bar 17 will also slide down, so that the control gear 141 rotates in the opposite direction, and the outer protective shell 14 reversely rotates 180 degrees, and then rotates again to open, so that the inner protective shell 13 can perform signal reception, reflection and The enhanced function avoids the loss of data packets due to the loss of signal reception, which affects the normal use of wireless network signal reception by users.
