Hereinafter, a preferred embodiment of the dome-type surveillance camera housing airtightness testing device according to the present invention will be described in more detail based on the attached drawings.

Here, in all the drawings below, components having the same function are given the same reference numerals, and repeated descriptions are omitted. In addition, the terms described below are defined in consideration of the functions in the present invention, and this is a unique commonly used term. It is specified that it should be interpreted as meaning.

As shown in Figure 1, the dome-type surveillance camera housing airtightness testing device 100 according to the present invention is roughly divided into a jig 110, a sealing means 120, and an air supply means 130.

The jig 110 is formed with a seating portion 111 on which the dome-shaped surveillance camera housing 200 formed with the dome-shaped cover 210, the left LED module 220, and the right LED module 230 is seated, and the dome-shaped surveillance camera housing 200 is seated. The dome-shaped cover 210 of the camera housing 200 is formed at a predetermined inclination angle with respect to the installation surface so that it is horizontal.

The dome-shaped surveillance camera housing 200 is equipped with a dome-shaped cover 210 in a cover mounting hole (not shown) formed in the center of one side, and a left LED mounting hole (not shown) is formed on the left side of the cover mounting hole to accommodate the left LED. The module 220 is mounted, and a right LED mounting hole (not shown) is formed on the right side of the cover mounting hole, and the right LED module 230 is mounted.

In addition, it is preferable that a rubber gasket 112 for airtightening the bottom of the dome-shaped surveillance camera housing 200 mounted on the seating portion 111 is formed to be detachable.

In addition, the seating portion 111 has an air leak confirmation hole 111a formed at the lower portion of the dome-shaped cover 210 of the dome-shaped surveillance camera housing 200 on which it is seated.

The air leak confirmation hole (111a) is used when air is injected into the dome-shaped cover (210) of the dome-shaped surveillance camera housing (200) mounted on the seating portion (111), the left LED module (220), and the right LED module (230). This was done to check for leaks.

And, the reason why the jig 110 is formed to form a predetermined inclination angle with respect to the installation surface is because the dome-shaped cover 210 portion of the dome-type surveillance camera housing 200 forms a predetermined inclination angle with respect to the floor surface.

In other words, when the jig 110 is formed to be flush with the installation surface, the dome-shaped cover 210 of the dome-shaped surveillance camera housing 200 mounted on the seating portion 111 forms an inclination angle.

In this case, it is difficult to seal the dome-shaped cover 210 using the sealing means 120, and workability is reduced.

However, when the jig 110 is installed at a predetermined inclination angle, the dome-shaped cover 210 of the dome-shaped surveillance camera housing 200 mounted on the protruding seating portion 111 becomes horizontal.

Therefore, it is desirable to form the jig 110 to form a predetermined inclination angle with respect to the installation surface.

The sealing means 120 includes a central seal 122 that is linked to the expansion and contraction of the piston rod 121a of the main cylinder 121 to surround and seal the dome cover 210 of the dome surveillance camera housing 200. The left sealer 124 that seals the left LED module 220 of the surveillance camera housing 200 in conjunction with the expansion and contraction of the piston rod 123a of the left cylinder 123 located to the left of the sealer 122 and the above. It includes a right sealer 126 that seals the right LED module 230 in conjunction with the expansion and contraction of the piston rod 125a of the right cylinder 125 located to the right of the central sealer 122.

In addition, the sealing means 120 further includes a pressure gauge 127 to check whether the dome-type surveillance camera housing 200 is airtight.

Here, the pressure gauge 127 is connected to the air leak confirmation hole 111a of the seating portion 111.

In addition, a compressed air injection hose 121b is installed on each side of the main cylinder 121, the left cylinder 123, and the right cylinder 125 to inject compressed air supplied from the air supply means 130, (123b) and (125b) are connected, and compressed air discharge hoses (121c), (123c) and (125c) are connected to one side of the tile to discharge the supplied compressed air.

In addition, the central seal 122, the left seal 124, and the right seal 126 have seal rings 122a and 124a having a circular cross-section along the circumference and shape at the front end surface. , (126a) is formed, and on one side of each side there are compressed air injection hoses (122b), (124b), ( 126b) is connected.

In addition, the left cylinder 123 and the right cylinder 125 are installed to form a predetermined inclination angle through a separate frame (not shown).

For example, the left sealer 124 and the right sealer 126 are connected to the left LED module 220 and the right LED module ( 230) are installed at a predetermined inclination angle so that they are in close contact with each other.

Therefore, the present invention can quickly and accurately seal the dome-shaped cover 210, the left LED module 220, and the right LED module 230 of the dome-shaped surveillance camera housing 200, which is curved in geometric form.

In addition, the main cylinder 121, the left cylinder 123, and the right cylinder 125 are connected to the central seal 122, the left seal 124, and the right seal 126 in the dome-type surveillance camera housing 200. )'s dome-shaped cover 210 and the left LED module 220 and right LED module 230 are configured to simultaneously expand and contract by operating the air input/output switch 129, which is installed separately.

In addition, the pressure gauge 127 is connected to the dome-shaped cover 210 and the left LED module of the dome-shaped surveillance camera housing 200 through the central seal 122, the left seal 124, and the right seal 126 ( When compressed air is injected into 220) and the right LED module 230, it will not operate if the airtightness is perfect.

Conversely, the dome-shaped cover 210, the left LED module 220, and the right LED module of the dome-shaped surveillance camera housing 200 through the central seal 122, the left seal 124, and the right seal 126. When compressed air is injected into (230), if the airtightness is not perfect and air flows into the inside of the surveillance camera housing (200), the pressure air is transmitted to the pressure gauge (127) through the air leak confirmation hole (111a) to operate. I do it.

The air supply means 130 includes air compressors 131 that supply compressed air, and compressed air generated from the air compressor 131 is supplied to the main cylinder 121 and the left cylinder 123. and a first solenoid valve 132 that supplies or discharges pressure to the right cylinder 125 at a predetermined pressure to seal or unseal the dome-type surveillance camera housing 200, and from the air compressor 131. The generated compressed air is supplied at a predetermined pressure to the central seal 122, the left seal 124, and the right seal 126, and the dome-shaped cover 210 formed on the dome-shaped surveillance camera housing, the left LED module 220, and It includes a second solenoid valve 133 that allows checking whether the assembled state and molding state of the right LED module 230 are airtight.

In addition, a first pressure gauge (132a) and a second pressure gauge (133a) are provided on one side of the first solenoid valve (132) and the second solenoid valve (133).

Here, the first pressure gauge (132a) displays the pressure of air supplied to the first solenoid valve 132, and the second pressure gauge (133a) indicates the pressure of air supplied to the second solenoid valve 133. is displayed.

For example, the first solenoid valve 132 operates to supply air at a pressure of 0.4 bar, and the second solenoid valve 133 operates to discharge air at a pressure of 0.2 bar.

That is, the pressure of the first solenoid valve 132 must be higher than that of the second solenoid valve 133 to confirm air leakage.

In addition, the air supply means 130 has an air input/output switch 134 and an air supply switch 135 formed on one side.

When the air input/output switch 134 is turned ON, the compressed air produced by the air compressor 131 is supplied to the main cylinder 121, the left cylinder 123, and the right cylinder 125 through the first solenoid valve 132. Compressed air is supplied through the injection hoses 121b, 123b, and 125b connected to one side of each side, and when the air input/output switch 134 is turned OFF, the main cylinder 121, the left cylinder 123, and the right cylinder The air supplied to (125) is discharged through the compressed air discharge hoses (121c), (123c), and (125c).

And, the compressed air supply switch 135 consists of a main switch 135a, a left seal switch 135b, a central seal switch 135c, and a right seal switch 135d.

The compressed air supply switch 135 supplies compressed air produced from the air compressor 131 by opening and closing the main switch 135a to the central seal 122 and the left side through the second solenoid valve 133. Compressed air can be supplied simultaneously to the compressed air injection hoses 122b, 124b, and 126b connected to the seal 124 and the right seal 126.

In addition, the left seal switch 135b, the central seal switch 135c, and the right seal switch 135d can be opened and closed respectively.

The operational relationship of the present invention configured as above will be described as follows.

First, as shown in FIG. 2, the airtightness test of the dome-type surveillance camera housing 200 using the dome-type surveillance camera housing airtightness test device 100 according to the present invention is performed by placing a dome-shaped Install the surveillance camera housing (200).

Next, when the air input/output switch 134 is turned ON, the first solenoid valve 132 injects compressed air produced through the air compressor 131 into the compressed air injection hoses 121b, 123b, and 125b. It is supplied to the main cylinder 121, the left cylinder 123, and the right cylinder 125.

As a result, as shown in FIG. 3, the piston rods 121a, 123a, and 125a of the main cylinder 121, the left cylinder 123, and the right cylinder 125 are extended, and in conjunction with this, the The central seal 122, the left seal 124, and the right seal 126 descend to the outside of the dome-shaped cover 210 of the dome-shaped surveillance camera housing 200, the outside of the left LED module 220, and the right LED module ( 230) It adheres closely to the outskirts.

That is, the central seal 122, the left seal 124, and the right seal 126 are formed on the dome-shaped surveillance camera housing 200, the dome-shaped cover 210, the left LED module 220, and the right LED module ( 230) covers the outer shell larger than each mounting hole that accommodates it.

At this time, between the cover mounting hole (not shown) formed in the dome-shaped surveillance camera housing 200 and the dome-shaped cover 210, between the left LED mounting hole (not shown) and the left LED module 220, and the right LED mounting hole (not shown) Between the central sealer 122 and the right LED module 230, seal rings 122a, 124a, and 126a of the left sealer 124 and the right sealer 126, respectively. ), a closed space is formed.

Next, as shown in FIG. 4, when the main switch 135a of the compressed air supply switch 135 is opened while the dome-type surveillance camera housing 200 is sealed, the second solenoid valve 133 releases air. Compressed air produced through the compressor 131 is supplied to the central seal 122, the left seal 124, and the right seal 126 through each compressed air injection hose 122b, 124b, and 126b. Between the cover mounting hole (not shown) and the dome-shaped cover 210, between the left LED mounting hole (not shown) and the left LED module 220, and between the right LED mounting hole (not shown) and the right LED module 230. supply between

At this time, the supplied compressed air is between the cover mounting hole (not shown) formed in the dome-shaped surveillance camera housing 200 and the dome-shaped cover 210, between the left LED mounting hole (not shown) and the left LED module 220, and on the right. It is injected into the sealed space formed between the LED mounting hole (not shown) and the right LED module 230.

In addition, if the compressed air supplied to the dome-shaped cover 210, the left LED module 220, and the right LED module 230 of the dome-shaped surveillance camera housing 200 does not flow into the interior of the surveillance camera housing 200, the dome-shaped cover (210), the left LED module 220, and the right LED module 230 are well attached and air tight, and the pressure gauge 127 indicates that there is no change in pressure.

However, as shown in FIG. 5, the compressed air supplied to the dome-shaped cover 210, the left LED module 220, and the right LED module 230 of the dome-shaped surveillance camera housing 200 is injected into the surveillance camera housing 200. When it flows inside, one or more of the dome-shaped cover 210, the left LED module 220, and the right LED module 230 are not airtight, and the pressure gauge 127 is exposed through the air leak confirmation hole 111a. Since the pressure is transmitted to the pressure gauge 127, the pressure is displayed as increased.

At this time, the worker must use the left seal switch 135b and the central seal switch to accurately check which part of the dome cover 210, the left LED module 220, and the right LED module 230 is leaking air. (135c) and the right air seal switch (135d) are opened and closed one by one in order to find and select the air leakage area.

For example, when the left seal switch 135b of the compressed air supply switch 135 is opened, the compressed air produced through the air compressor 131 flows through the left seal 124 through the compressed air injection hose 124b. When supplying air to the left LED module 220, whether the air is leaking is checked by checking whether the pressure of the pressure gauge 127 increases.

Next, the central seal switch 135c of the compressed air supply switch 135 is opened and operated to allow compressed air produced through the air compressor 131 to enter the central seal 122 through the compressed air injection hose 122b. When supplying air to the dome-shaped cover 210, whether the air is leaking is checked by checking whether the pressure of the pressure gauge 127 increases.

Then, the right seal switch 135d of the compressed air supply switch 135 is opened and operated to allow compressed air produced through the air compressor 131 to enter the right seal 126 through the compressed air injection hose 126b. When supplying air to the right LED module 230, whether the air leakage is checked by checking whether the pressure of the pressure gauge 127 increases.

In this way, when the airtightness of the dome-type surveillance camera housing 200 is determined to be good or bad through the pressure gauge 127, the inspector (worker) turns the air input/output switch 134 OFF to open the first solenoid valve 132. Compressed air supplied to the main cylinder 121, the left cylinder 123, and the right cylinder 125 is discharged through the compressed air discharge hoses 121c, 123c, and 125c.

As a result, as shown in FIG. 6, the piston rods 121a, 123a, and 125a of the main cylinder 121, the left cylinder 123, and the right cylinder 125 contract, and in conjunction with this, the piston rods 121a, 123a, and 125a contract. The central sealer 122, the left sealer 124, and the right sealer 126 are raised and lowered to connect the dome-shaped cover 210, the left LED module 220, and the right LED module 230 of the dome-shaped surveillance camera housing 200. is separated from (separated from)

Afterwards, the inspector separates the dome-type surveillance camera housing 200 for which the airtightness test has been completed from the seating portion 111 of the jig 110, moves it to a bad or good selection position, and installs another dome-type surveillance camera housing 200 for the airtightness test. is seated on the seating portion 111 of the jig 110 and the same operation as above is performed.

Therefore, through this operation, the inspector can easily, quickly, and precisely inspect whether the airtightness of the dome-type surveillance camera housing is good or bad.
