For example, without limitation, it should be appreciated that those skilled in the art will, in light of the teachings of the present invention, recognize a multiplicity of alternate and suitable approaches, depending on the needs of the particular application, to implement the functionality of any given detail described herein, beyond the particular implementation choices in the following embodiments described and shown. That is, there are numerous modifications and variations of the invention that are too numerous to be listed but that all fit within the scope of the invention. Also, singular words should be read as plural and vice versa and masculine as feminine and vice versa, where appropriate, and alternative embodiments do not necessarily imply that the two are mutually exclusive.
The present invention will now be described in detail with reference to embodiments thereof as illustrated in the accompanying drawings.
Embodiments of the present invention provide liquid handling system containment devices that reduce cost of installation, simplify service and replacement of liquid handling systems, create protected space for liquid handling systems, and protect liquid handling systems from the elements such as, but not limited to, rain, snow, freezing, and heat. These embodiments also minimize vandalism by being out of site and having a secure lid. The lid in these embodiments may also be colored to minimize visibility of the containment device.
The preferred embodiment of the present invention is designed to hold a liquid handling system by the use of quick connect devices, enabling easy removal of the liquid handling system for service and replacement. No entrance into the vault is required. By servicing the liquid handling system components above ground, the need to enter the containment device is eliminated. Therefore, confined space is not an issue with the preferred embodiment, and not having to enter the vault eliminates hazardous gasses issues. Not entering the containment device also generally climinates clear area issues for electrical appliances needed, for example, without limitation, pressure switches, disconnects, junction boxes, breaker panels, etc.
In the present embodiment, vault assembly 20 is comprised of a molded or fabricated vault 8 of adequate construction to withstand soil pressures to prevent distortion or collapsing when buried underground up to a lid 1. Vault 8 is preferably constructed of a plastic or galvanized steel, but may be constructed of various alternate materials such as, but not limited to, aluminum or other metals. Vault 8 houses a quick connect system and a liquid handling device 4 connected to the quick connect system. The top of vault 8 has a ridge that enables lid 1 to seal to vault 8 and areas adequate to fasten lid 1 to vault 8 with fasteners 2 for security and safety. Fasteners 2 are designed to make removal of lid 1 difficult, adding to security. Fasteners 2 may be, for example, without limitation, latches, hooks, or bolts passing through lid 1 and threaded into vault 8, to secure lid 1 to vault 8. Lid 1 may be constructed of molded plastic or fabricated metal dependant on traffic, security, and aesthetic needs.
Vault 8 comprises a bottom to prevent pests from entering and provisions for drainage that may be needed. A quick connect base 11, the first half of the quick connect system, is attached to a supporting device 10 that is also attached to other areas of vault 8 to support the weight of the liquid handling system being installed in vault 8. Quick connect base 11 is bolted or welded to vault 8 to hold quick connect base 11 square. Liquid handling device 4 connects to bracket 5 by means such as, but not limited to clamps or bolts. Bracket 5 holds the second half of the quick connect system, a quick connect shoe 6, and holds quick connect shoe 6 inline with quick connect base 11, assuring proper alignment and support of liquid handling device 4. Liquid handling device 4 is installed or removed by a lifting pipe 3 that is installed on bracket 5. In alternate embodiments a handle on liquid handling device 4 may be used for lifting liquid handling device 4 out of vault 8. Liquid handling device 4 may be any device connected to a pumping system such as, but not limited to, a pump, tank, meter, filter, valving, etc.
In the present embodiment, when lifting liquid handling device 4 out of vault 8, typical plumbing 7 is disconnected by quick connect shoe 6 and quick connect base 11 separating in a vertical direction. To install quick connect assembly with pumping device 4 into vault 8, the user slides quick connect assembly with liquid handling device 4 into the cavity of vault 8 in a vertical direction and aligns alignment feature 17 which guides quick connect shoe 6 into quick connect base 11, thereby enabling quick connect shoe 6 to enter quick connect base 11 and pressing down until bracket 5 and a base supporting bracket 10 touch. At this point, plumbing 7 is connected, allowing fluid to pass from liquid handling device 4 through plumbing 7 to quick connect through shoe 6 and base 11 and on to external plumbing 9.
External plumbing 9 enables items inside of vault 8 to be connected to mainlines outside of vault 8. In some embodiments, plumbing 7 may be modified to accept a miniature quick connector 7a, as shown by way of example in
In some embodiments these accessory devices may also be connected by a small quick connect adapter similar to the quick connect adapter, shown by way of example in
By constructing vault 8 from plastics or thin gauge metals, vault 8 can be delivered in a pickup truck or trailer and set into an existing ditch by one person, without lifting equipment or with minimal lifting equipment. Installation is very quick. The only water connections that require attention at installation are external plumbing 9 positioned outside of vault 8 below the freezing level. Vault 8 is designed to control fluids by minimizing or eliminating rainwater and groundwater from entering. However, caution must be used when installing vault 8 in high water tables. In these situations water removal means such as, but not limited to, drains, sump pumps, or holes may be used to drain or remove any fluids that enter vault 8. Vault 8 is installed in the ground after a waterline ditch has been dug, and water lines are connected to plumbing 9 at this time. A typical installation of vault assembly 20, according to the present embodiment, is as follows.
After the excavator digs ditches for vault 8 and lines, vault 8 is placed in the ditch. The ditch must be of adequate width and depth to enable vault 8 to be buried to the level of lid 1 at the point of installation. Water lines are then connected to external plumbing 9 at vault 8. Liquid handling device 4 can be in vault 8 at this time or may be installed into vault 8 after backfilling. If liquid handling device 4 is to be installed after backfilling, the excavator then backfills the ditch. Liquid handling device 4 along with bracket 4 is lowered into vault 8. Alignment feature 17 guides quick connect shoe 6 into quick connect base 11, and quick connect shoe 6 and quick connect base 11 are aligned. Bracket 4 with Liquid handling device 4 is then pushed into place. If electrical is needed, the electrical system is wired at this point. Lid 1 and fasteners 2 are then installed. If liquid handling device 4 requires service, fasteners 2 and lid 1 are removed and bracket 5 with liquid handling device 4 is lifted out of vault 8. Liquid handling device 4 may be serviced and then reinstalled into vault 8 as described above.
Liquid handling device 4 that is housed in vault 8 may be assembled at a factory, in a shop, or in the field by service personnel. In the present embodiment, all other components are comprised in vault 8. Electrical connections are preferably performed by an electrician. Controllers and other items such as, but not limited to switches, disconnects, J boxes, etc. may be installed on a post, inside vault 8, or inside other structures as preferred. Vault 8 has a plastic or metallic lid 1 that seals to vault 8 attached with fasteners 2 to supply security and safety. This design enables many different components to be installed in vault 8, for example, without limitation, pumps, meters, filters, pressure tanks, etc. The physical size of vault 8, quick connect shoe 6, and quick connect base 11, bracket 5 and base support bracket 10 can be changed to facilitate equipment of different sizes, for example, without limitation, larger tanks, pumps, filters, meters, etc. Special ordered systems can be built individually as needed.
Being able to install the vault assembly outside, according to the present embodiment, provides space saving in buildings where the liquid handling system is needed. However, in alternate embodiments, this vault assembly may be installed in the floor of structures if needed.
An embodiment of the invention may be configured to enable the component parts of the foregoing liquid handling device to be removable from the housing using the quick connect shoe 6 and base 11 mounted to the sidewall of Vault 8 without using brackets 5 an 10 as shown in
