Description

Technical Field

[0002] A wireless sensor network is a distributed sensor network whose terminals are sensors that can sense and inspect the outside world. Its principle is mainly to communicate wirelessly, so the network settings are flexible, the location of the equipment can be changed at any time, and it can be connected to the Internet by wire or wireless.

[0026] A hole for the connecting rod to slide is provided inside the box body.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] 1. By designing an active cavity, a slide plate, a partition, a through hole, a thermistor and an electromagnet, when the temperature inside the data collection device is high, its internal temperature will be sensed by the thermistor, and then as the temperature rises, the resistance of the thermistor decreases, which increases the current in the circuit where the electromagnet is located, and increases the magnetic force of the electromagnet. At this time, the slide plate is adsorbed by the electromagnet, so that the slide plate will overcome the potential energy of the spring and slide down, thereby driving the partition plate to slide down. After the partition plate slides down, the through hole will be opened, so that air convection will be formed between the through holes on both sides of the box body, thereby accelerating the heat dissipation inside the box body.

[0029] 2. By designing the movable cavity, slide plate, partition, through hole, thermistor and electromagnet, when the heat dissipation inside the box is completed, as the temperature decreases, the resistance of the thermistor increases, and the current value of the circuit where the electromagnet is located will decrease, causing the magnetic force of the electromagnet to decrease. At this time, the slide plate will slide up due to the potential energy of the spring, thereby driving the partition plate to move up, and the through hole will be blocked by the slide plate to prevent dust from the outside from entering the inside of the box.

[0030] 3. By designing the connecting rod, collecting chamber, piston plate and air pipe, when the partition moves down to open the through hole, the partition is used to drive the connecting rod to move down, so that the connecting rod drives the piston plate to move down, causing the volume of the cavity on the upper side of the piston plate in the collecting chamber to increase, thereby generating negative pressure. At this time, the negative pressure is transmitted through the air pipe, so that the dust accumulated at the through hole is sucked into the collecting chamber, thereby preventing the dust accumulated at the through hole when the through hole is opened from entering the inside of the box body, thereby improving the dustproof effect of the data collection device.

[0040] The thermistor 31 is a negative temperature coefficient resistor, and its resistance value decreases as the temperature increases, and vice versa, its resistance value increases as the temperature decreases.

[0041] See also Figure 1-Figure 4 The left and right side walls of the box body 1 are symmetrically provided with movable cavities 12 on the upper side of the electromagnet 11 .

[0042] A slide plate 13 is slidably connected inside the movable cavity 12 . The slide plate 13 is made of a magnetic material, and the magnetism of the slide plate 13 is opposite to that of the electromagnet 11 , so that the electromagnet 11 can adsorb the slide plate 13 and cause the slide plate 13 to slide down.

[0043] See also Figure 1-Figure 4 A spring 14 is fixedly welded to the middle of the bottom surface of the slide plate 13 , and the bottom end of the spring 14 is fixedly welded to the bottom surface of the inner cavity of the active cavity 12 for resetting the slide plate 13 .

[0044] A partition plate 15 is fixedly welded to the middle of the top surface of the slide plate 13 , and a groove for the partition plate 15 to slide is provided inside the box body 1 .

[0045] See also Figure 1-Figure 4A through hole 16 is formed inside the left and right side walls of the box body 1 and located on the upper side of the active cavity 12 .

[0046] When the partition 15 is at the uppermost stroke, the partition 15 completely blocks the through hole 16 , preventing the return from the outside from entering the interior of the box body 1 .

[0047] See also Figure 1-Figure 4 A collecting chamber 17 is provided inside the left and right side walls of the box body 1 and located on the upper side of the through hole 16. A piston plate 18 is slidably connected inside the collecting chamber 17.

[0049] See also Figure 1-Figure 4 A connecting rod 151 is fixedly welded to the middle of the top surface of the partition 15, and the upper part of the connecting rod 151 extends into the interior of the collecting chamber 17 and is fixedly welded to the middle of the bottom surface of the piston plate 18 to ensure that when the partition 15 moves downward, the piston plate 18 is driven downward by the connecting rod 151.

[0050] The box body 1 has a hole inside for the connecting rod 151 to slide.

[0051] Working principle: When the data collection device of the wireless sensor network operates normally, the internal temperature of the box body 1 gradually increases, so that the high temperature inside the box body 1 is sensed by the thermistor 31, which in turn causes the resistance of the thermistor 31 to decrease, causing the resistance of the circuit where the electromagnet 11 is located to decrease and the current value to increase, thereby increasing the magnetic force of the electromagnet 11. At this time, the electromagnet 11 is used to adsorb the slide plate 13, so that the slide plate 13 overcomes the potential energy of the spring 14 and slides down, and the slide plate 13 drives the partition 15 to slide down, and the partition 15 opens the through hole 16, so that air convection is formed between the through holes 16 on both sides of the box body 1, which promotes the heat dissipation inside the box body 1. When the heat dissipation is completed, the temperature inside the box body 1 decreases, so that the resistance of the thermistor 31 increases, thereby causing the magnetic force of the electromagnet 11 to decrease, so that the spring 14 is used again. The potential energy causes the slide plate 13 to move upward, and the slide plate 13 drives the partition plate 15 to move upward. At this time, the partition plate 15 is used to block the through hole 16 to prevent the dust from the outside from entering the interior of the box body 1. Secondly, since there is a time interval between the opening and blocking of the through hole 16 by the partition plate 15, and dust will inevitably accumulate at the through hole 16 during this time interval, during the downward movement of the partition plate 15, the partition plate 15 will drive the connecting rod 151 to move downward, so that the connecting rod 151 drives the piston plate 18 to move downward. After the piston plate 18 moves downward, the volume of the cavity on the upper side of the piston plate 18 in the collection chamber 17 will increase, thereby generating negative pressure. Through the connection of the air pipe 19, the negative pressure acts on the through hole 16, thereby sucking the dust accumulated at the through hole 16 into the collection chamber 17, further improving the dustproof effect of the data collection device of the wireless sensor network.
