The spring part 330 is located under the magnetic body 320 and has elasticity.

The shape of the spring part 330 is shown in the form of a compression spring, but a leaf spring or a torsion spring may be used.

The upper fixing part 350 is formed on the upper side of the magnetic body 320 and is fixed without a gap.

In addition, the upper fixing part 350 prevents the inflow of contaminants and fluids that may be introduced into the opening and closing part 300, and the magnetic body 320 and the column part 340, which may be generated due to the elasticity of the spring part 330, There is an effect of preventing the separation of the.

The lower fixing part 360 is formed in contact with the lower part of the spring part 330.

In addition, the lower fixing portion 360 serves as a support plate supporting the spring portion 330 compressed when the column portion 340 descends.

Therefore, the lower fixing part 360 has the effect of closely supporting the spring part 330.

When the column part 340 is lowered with reference to FIG. 6(b), the shape of the opening/closing part 300 will be described in detail. Between the upper fixing part 350 and the magnetic body 320, the spring part 330 is compressed.

The cap part 400 to be described later is closed and sealed by the downward motion of the column part 340. Detailed description will be given later.

The cap part 400 of the present invention will be described with reference to FIG. 5.

It is preferable that the cap part 400 is in the form of a disk and has the same diameter as the body part 100.

The cap part 400 is formed in contact with the upper side of the column part 340, and includes a metal part 410.

The metal part 410 is formed at a corresponding position in contact with the electromagnet part 220 described above.

The metal part 410 comes into contact with the magnetic electromagnet part 220 of the upper body part 200 to seal the cap part 400.

When the metal part 410 and the electromagnet part 220 come into contact with each other, the above-described solenoid 310 becomes non-electric, and the cap part 400 is sealed only by the magnetic force of the metal part 410 and the electromagnet part 220. do. Detailed description will be given later.

The metal part 410 is preferably a ferromagnetic material, and the material is the same as the material of the magnetic material 320 described above.

The principle of sealing or opening the cap part 400 for moisture-proof and waterproof will be described in detail.

First, a process in which the cap part 400 is sealed will be described.

Referring to FIG. 3, the first water level sensor unit 130 and the second water level sensor unit 140 located inside the body unit 100 measure the presence or absence of fluid flowing into the body unit 100.

When the first level sensor unit 130 and the second level sensor unit 140 recognize the presence or absence of a fluid, the solenoid 310 is energized by the controller 150 as shown in FIG. 6(b), and the magnetic body 320 ) By generating a magnetic force, the column part 340 moves downward and the spring part 330 is compressed.

At this time, the electromagnet part 220 is also energized at the same time, and when the cap part 400 in contact with the column part 340 descends, the electromagnet part 220 comes into contact with the metal part 410 by magnetic force.

When the cap part 400 is sealed and the metal part 410 and the electromagnet part 220 come into contact with each other, the solenoid 310 is not energized and the electromagnet part 220 maintains energization so that the cap part 400 is continuously sealed. .

The waterproof packing 210 of the upper body part 200 which is in contact with the cap part 400 is sealed against contamination and fluids that may be introduced from the upper part of the body part 100 due to a step, corrosion, contraction, etc. of the waterproof kit 10. It prevents inflow.

In addition, there is an advantage of tightly sealing the inside of the hollow part 110 by blocking air that may be introduced.

Therefore, when the waterproof packing 210 is sealed, it has the effect of increasing the durability of the waterproof kit 10 by preventing the inflow of contaminants, fluids, and air, and the waterproof packing 210 is easy to attach and detach, making it convenient for the operator. It has the advantage of just replacing it.

When the cap part 400 is sealed as shown in FIG. 7, an air pocket is formed in the hollow part 110 inside the body part 100, and the fluid L does not flow in as much as the volume of air in the air pocket. There is an effect of preventing the sensor and controller 150 from being flooded.

When the air pocket is described in detail, if the air remaining inside the tube or object that is blocked by one side immersed in the fluid cannot escape, the air pocket remains inside.

The volume and pressure that the air occupies on the fluid that is about to flow into the pipe or the object by the volume of the air bag remaining inside the fluid pressurizes the fluid to prevent the inflow of the fluid.

Next, a process in which the cap part 400 is opened will be described.

When the water level is lowered, the cap part 400 is opened to remove moisture present inside.

The open form is as shown in FIGS. 1 and 3.

The principle that the cap part 400 is opened is when the first water level sensor part 130 and the second water level sensor part 140 do not recognize the fluid, the electromagnet part 220 is first turned off by the controller 150.

The non-conductive electromagnet part 220 is prevented from being magnetically attached to the metal part 410.

At the same time, the solenoid 310 is reversely energized, and due to the reverse energization of the solenoid 310, the column part 340 ascends as shown in FIG. 6(a), and the elastic recovery force of the spring part 330 is added to the cap part. 400 is open.

The elastic recovery force of the spring portion 330 is added, so that the column portion 340 can move up quickly, and the solenoid 310 does not need to conduct unnecessary current.

Therefore, the durability of the solenoid 310 is increased, and there is an advantage of maximizing a moisture-proof effect by opening the cap part 400 quickly.

When the cap 400 is opened, moisture escapes and is removed from the inside of the body 100.

Since moisture is removed, it is possible to prevent degradation and failure of the sensor, and there is an effect of increasing durability by preventing corrosion and rust of the waterproof kit 10.

With reference to FIG. 8, the relationship between the solenoid 310 and the electromagnet 220 of the present invention will be described in detail.

First, the table of FIG. 8(a) shows a case where the first water level sensor unit 130 and the second level sensor unit 140 recognize a fluid.

At this time, the solenoid 310 is energized, and at the same time, the electromagnet unit 220 is energized.

The reason for this is to lower the column part 340 by energization of the solenoid 310 so that the cap part 400 approaches the upper body part 200, and the electromagnet part 220 is energized to the cap part 400 and the body part. When the side part 200 abuts, that is, when the electromagnet part 220 comes into contact with the metal part 410 located on the cap part 400 by magnetic force, the purpose is to keep it to be sealed.

The table of FIG. 8(b) is a case where the column part 340 moves downward due to the operation of the solenoid 310 and the cap part 400 and the upper body part 200 come into contact with each other.

At this time, the solenoid 310 is not energized, and the electromagnet unit 220 maintains energization.

This is because the electromagnet part 220 and the metal part 410 come into contact with each other when the column part 340 descends due to the solenoid 310 being energized, and only the magnetic force of the electromagnet part 220 and the metal part 410 Since the 400 can be sealed, the solenoid 310 is non-conductive, and heat generated in the solenoid 310 due to energization or deformation of the spring portion 330 and the column portion 340 due to heat can be prevented. .

In addition, it is preferable that the force that the metal part 410 and the electromagnet part 220 contact and maintain by magnetic force is greater than the elastic recovery force of the spring part 330 of the opening/closing part 300.

The table of FIG. 8(c) shows the case where there is no fluid recognized by the first level sensor unit 130 and the second level sensor unit 140 (no fluid is recognized).

At this time, the solenoid 310 is reversely energized, and the electromagnet unit 220 is de-energized.

For this reason, when there is no fluid to be recognized, the cap 400 must be opened for a moisture-proof function.

In order for the cap part 400 to be opened, first, the magnetic force of the electromagnet part 220 and the metal part 410 must be stopped.

In order to stop the magnetic force, the electromagnet part 220 is non-energized and separates from the metal part 410, and the solenoid 310 is reversely energized to move the column part 340 upward to move the column part 340 upward. The cap part 400 is opened.

When the opening of the cap part 400 is completed, the solenoid 310 becomes non-conductive.

Although not shown in the drawing, various sensors, measuring instruments, and meters may be included in the waterproof kit 10, and may be used regardless of the type.

In addition, there may be slight differences in the location and direction of installation, and the optimum sensor and usage range can be determined for various measurement values, such as the measurement values desired by the user, for example, gas concentration, pollutant concentration, heavy metal concentration, etc.

9 and 10 illustrate a waterproof kit 20 according to another embodiment of the present invention.

First, the outer shape of the waterproof kit 10 described above is made in a circular shape. The curved shape is used by being fixed to the wall surface W with a curved fixing member S. When using a curved fixing member (S) fixed to the wall surface (W), it has the advantage of being easy to insert into a curved pipe or channel (P), but it has the disadvantage of using a separate fixing member (S). Occurs.

Referring to FIG. 9 to compensate for this disadvantage, the waterproof kit 20 according to another embodiment has a rectangular shape. This rectangular shape has the advantage of being able to intuitively fix the body part 600 using a bolt or nut without the need for a curved fixing member S.

Alternatively, even if it is used outside of a manhole and an enclosed space, since it has a rectangular shape, it is easy to mount on a cradle or install on a right-angled structure.

Referring to FIG. 10, the cap portion 500 includes an upper side portion 510 of the cap portion that inclines toward an end from the center portion and a cap portion stepped portion 520 formed to protrude downward from the end portion.

It is preferable that the cap portion 500 is longer than the length of the body portion 600 in the width direction and the length direction.

The upper side of the cap 510 is formed to be inclined from the center to the end, and fluids such as contaminants and rain dropping on the upper side of the cap 500 along the slope are flowed to the outside of the body 600 to be inside the waterproof kit 20. Prevent fluid from entering. Due to this structure, there is an effect of preventing the breakdown of the waterproof kit 20 and increasing durability.

The cap portion stepped 520 is protruding from the end when the cap portion 500 abuts against the body portion 600 and is sealed, so that there is an effect of once more blocking contaminants and fluids remaining in the cap portion upper portion 510 .

In addition, the diameter of the cap portion 500 is formed larger than the diameter of the body portion 600, when sealing the cap portion 500, a space is generated between the cap portion stepped 520 and the body portion 600. When fluid flows into this space, a surface tension is formed between the cap portion stepped portion 520 and the body portion 600 to prevent the fluid from flowing into the waterproof kit 20.
