Description

Technical Field

[0001] This utility model relates to an explosion-proof water tank device used in highly hazardous working environments such as chemical plants, oil drilling platforms, and oil refineries, and in particular, provides an explosion-proof water tank device connected to an explosion-proof camera for cleaning the surface of the camera lens. Background Technology

[0002] For various reasons, such as recording real-life situations, preventing crime, and collecting evidence, installing surveillance cameras in various locations, including residential areas, streets, factories, offices, and airports, is a common practice. However, in highly hazardous work environments such as chemical plants, oil drilling platforms, and oil refineries, cameras meeting special specifications must be installed for security monitoring. These special specifications mean that the cameras must possess sufficient strength to withstand a powerful explosion without being damaged. Otherwise, if the cameras are damaged by the external force of an explosion, it will be impossible to accurately record the scene of the accident, increasing the difficulty of determining the cause of the accident.

[0003] The aforementioned special-specification camera is called an "explosion-proof camera." Its structure involves installing the camera equipment inside a heavy metal casing, with reinforced glass at the front of the casing. The camera lens is aligned with this reinforced glass, allowing it to shoot from inside the casing. The heavy metal casing armor prevents the strong external force of an explosion from damaging the camera equipment inside.

[0004] After a period of use, the camera lens will become contaminated due to weather and environmental factors, affecting the quality and effect of the acquired images. This is especially noticeable in harsh environments such as chemical plants, oil drilling platforms, and oil refineries. Therefore, it is necessary to clean the glass surface of the camera lens regularly.

[0005] Because factories, workshops, airports, and other similar locations cover a large area and require a large number of explosion-proof cameras, manually cleaning the lenses of individual cameras is extremely time-consuming and labor-intensive. To address this issue, a known solution is to equip each group of explosion-proof cameras with a water tank device. This water tank device automatically supplies water or cleaning fluid to spray onto the glass surface of the camera lens, which is then cleaned by a wiper mounted on the camera.

[0006] To meet the explosion-proof requirements of highly sensitive environments such as those prohibiting smoking and open flames, the water tank device must also be explosion-proof. To prevent the water tank device from becoming an ignition point for an explosion, existing technology avoids using electrical equipment in the water tank device to prevent sparks from generating an explosion during operation. Therefore, existing technology uses a pneumatic device to pressurize the water or cleaning fluid in the water tank body to supply it to the explosion-proof camera; that is, each set of explosion-proof cameras is equipped with a water tank device equipped with a pneumatic device. Operators pre-inject high-pressure gas into the water tank body, and through a timer and valve control, the water or cleaning fluid in the water tank device is periodically and automatically sprayed onto the glass surface of the camera lens, where a wiper mounted on the camera then cleans the lens glass surface.

[0007] While the aforementioned pneumatic water tank device has the advantage of being explosion-proof, its disadvantage is that the gas pressure inside the tank will decrease after a number of spraying cycles. In addition, there is still a problem of slow gas leakage even when it is not in use. This results in insufficient distance and amount of water or cleaning fluid being sprayed onto the glass surface of the lens using air pressure. Therefore, the staff still have to spend a lot of physical strength and time circulating and replenishing high-pressure gas in the large factory / site area, which is very inefficient.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] like Figures 1 to 5 As shown, the explosion-proof water tank device provided by this utility model is an explosion-proof water tank device connected to an explosion-proof camera for cleaning the surface of the camera lens. Its preferred embodiment includes: a base 10, a circuit control unit 20, a water tank body 30, a water pump 40, an explosion-proof cover 50, and an electronic buoy 60. The base 10 can be formed by bending a metal plate into a base 101 and a vertical plate 103 connected to one side (i.e., the rear side) of the base 101. Side plates 105 are respectively connected to the opposite sides of the base 101 and the vertical plate 103, thereby forming a placement space between the base 101, the vertical plate 103, and the two side plates 105. A water outlet 107 is provided near the bottom of one of the side plates 105. Multiple screw holes 109 are provided on the top of the vertical plate 103 and the front part (i.e., the front side) of the base 101.

[0043] The circuit control unit 20 is located on the base 10, preferably fixed to the vertical plate 103 near the upper end, and is an electrical device for controlling the operation of the pumping motor 40 and the electronic buoy 60.

[0044] The water tank body 30 is located on the base 10, preferably made of metal or plastic and fixed on the base 101; the interior of the water tank body 30 is a space for holding water or cleaning fluid, and its upper end is provided with a water inlet and several holes (not shown) for passing through pipes.

[0045] A water pump 40 is located inside the water tank body 30. The water pump 40 is connected to a first electrical conduit 401A and extends upwards out of the water tank body 30. The first electrical conduit 401A is then connected to a circuit control unit 20. Furthermore, a second electrical conduit 401B is located in the circuit control unit 20 and extends out of a side plate 105 on one side of the base 10. The first electrical conduit 401A contains wires electrically connected to the water pump 40 and the circuit control unit 20; the second electrical conduit 401B contains wires electrically connected to the circuit control unit 20. The power cord connected to the external power source is waterproofed and protected against external damage through the first power cord conduit 401A and the second power cord conduit 401B. In addition, a water outlet pipe 403 is connected between the water pump 40 and the water outlet 107 of the base 10. The water outlet 107 is connected to a water supply pipe (not shown in the figure). When the water pump 40 is running, it draws water or cleaning fluid from the water tank body 30 and delivers it to the explosion-proof camera (not shown in the figure) through the water outlet pipe 403 and the water supply pipe. The water or cleaning fluid is then sprayed onto the lens surface of the explosion-proof camera through a nozzle.

[0046] Preferably, an electronic buoy 60 can also be installed inside the water tank body 30 to detect the stored water level. The electronic buoy 60 is connected to a buoy wire conduit 601 and extends out of the water tank body 30. The buoy wire conduit 601 is also connected to the circuit control unit 20. The buoy wire conduit 601 provides waterproof and external force protection for the wires located inside it.

[0047] The explosion-proof cover 50 is used in conjunction with the base 10 to completely enclose and provide protection for the circuit control unit 20, the water tank body 30, the first electrical conduit 401A, the second electrical conduit 401B, the buoy electrical conduit 601, and the water outlet pipe 403. More specifically, the explosion-proof cover 50 can be formed of a highly explosion-resistant material (e.g., a metal plate) having a top wall 501, a vertical wall 503 connected to one side (i.e., the front side) of the top wall 501, and side walls 505 connecting opposite sides between the top wall 501 and the vertical wall 503. Holes 507 corresponding to the aforementioned screw holes 109 are provided in the top wall 501 and the vertical wall 503; thereby, screws can be inserted through these holes 507 and locked into the screw holes 109 to fix the explosion-proof cover 50 to the base 10.

[0048] The usage of the explosion-proof water tank device of this utility model is described as follows: The circuit control unit 20 is electrically connected to an external power source and is operated and controlled by remote automated equipment and / or personnel. A start-up time is preset via a timer or manual operation. When the circuit control unit 20 controls the water pump 40 to start for a predetermined time and then stops, during the start-up time of the water pump 40, the water pump 40 draws water or cleaning fluid from the water tank body 30 and delivers it to the explosion-proof camera through the outlet pipe 403 and the water supply pipe. The water is then sprayed onto the lens glass surface of the explosion-proof camera through nozzles, and the lens glass surface is then cleaned by the wipers installed on the explosion-proof camera. Simultaneously, the electronic buoy 60 detects the water level in the water tank body 30 and transmits an electronic signal to the circuit control unit 20, which then transmits the signal to the remote control equipment. When the water level falls below a predetermined value, a predetermined signal is generated to notify personnel to replenish water or cleaning fluid in a timely manner. During the above operation, even if the circuit control unit 20 generates sparks due to short circuits or other faults, the sparks will not leak out because they are shielded by the explosion-proof cover 50, and therefore will not cause harm or explosion to the external sensitive environment.

[0049] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
