Description

BATTERY HOLDER DETACHABLY FIXED FOR TRANSPORT TO A

PUMP

TECHNICAL FIELD

The present disclosure relates to submersible pumps. More specifically, the present disclosure relates to a battery holder which provides benefits such as ease of transport when used with the submersible pumps.

BACKGROUND

Submersible pumps generally make use of one or more batteries for powering purposes. The batteries are generally housed inside a control housing (also referred to as a battery holder) for protection from outside agents such as rains, impurities and the like. Generally, conventional arrangement of the submersible pumps and the control housing make use of a flexible connection (say a fixed wire) to connect them for transfer of power. However, such conventional arrangements have constraints which make it difficult to transport the submersible pumps and the control housing together, which can severely hamper the portability of these arrangements.

Moreover, while ease of transport is quite crucial for a common user, there are also concerns regarding storage space occupied by the conventional arrangements which usually have a detached configuration of the submersible pumps and the control housing. Presently, there is a requirement to store the submersible pump and the control housing separately leading to a waste of storage space.

An example of a submersible pump is provided by EP1455092 (hereinafter referred to as’092 reference). The Ό92 reference provides a battery-driven pump with a motor and a battery, an adjustable control device for adjusting the power output of the battery to the motor. Further, the battery driven pump and the control device are connected by a supply line. However, the Ό92 reference does not disclose a means allowing convenient transport of the battery-driven pump and the control device together. Thus, there is a need of a battery holder which can provide various improvements for application with the submersible pumps.

SUMMARY

In view of the above, it is an objective of the present invention to solve or at least reduce the drawbacks discussed above. The objective is at least partially achieved by a battery transport system (BTS). The BTS includes a pump having a pump housing. The BTS includes a power source housed with a control housing. The BTS includes a flexible connection configured between the pump housing and the control housing. The BTS is characterized in that the pump housing can have a first locking feature. The control housing can have a second locking feature compatible for locking with the first locking feature. Further, locking the first locking feature and the second locking feature couples the pump housing with the control housing. The compatible locking features allow easy coupling and decoupling of the control housing with the pump housing.

According to an embodiment of the present invention, the power source is a battery. The battery can be any common battery (say a universal battery) which can optimally power the pump as per the requirement.

According to an embodiment of the present invention, the control housing includes at least a first compartment which houses the power source. Further, the control housing includes a second compartment which houses a control unit of the pump. This provides additional and improved options to control the pump even by using the control housing. Further, separate compartments for the power source and the control unit allow for ease of packaging of the power source, the control unit, and the associated wiring etc.

According to an embodiment of the present invention, the first locking feature and the second locking feature is selected from one or more of a snap-fit coupling, or a push-fit coupling between the pump housing and the control housing. The choice of locking type between the pump housing and the control housing gives an option to easily transport them together with minimum user effort. According to an embodiment of the present invention, the control unit is configured to perform variable levels of control of the pump. This can prove useful in cases where there is a requirement to provide only restricted access (say only power control) to control of the pump by using the control housing.

According to an embodiment of the present invention, the pump housing further includes slots around the first locking feature of the pump. The slots can serve as additional locking feature of the pump housing.

According to an embodiment of the present invention, the control housing further includes a pin around the second locking feature of the control housing. The pin with or without the second locking feature of the control housing can provide desired coupling action as elaborated later.

According to an embodiment of the present invention, locking the pin and the slots couples the control housing and the pump housing. This provides a more robust coupling of the control housing and the pump housing.

Other features and aspects of this invention will be apparent from the following description and the accompanying drawings.

Further, such shape along with a circular base (as shown in FIG. 2C) will provide compactness and portability during use of the BTS 100.

The first locking feature 202 can be selected taking into account specifications of any/both of the pump housing 112 and the control housing 120. More particularly, the first locking feature 202 shall be selected based upon dimensions, weights, life and the like of the pump housing 112 and the control housing 120. This will allow ease of transportation of the pump housing 112 and the control housing 120 with desired safety and convenience. FIG. 3 A illustrates a side perspective view of the control housing 120. The control housing 120 has a second locking feature 302 compatible for locking with the first locking feature 202. Further, locking the first locking feature 202 and the second locking feature 302 couples the pump housing 112 with the control housing

120.

The present disclosure illustrates general aspects such as position, type, size of the first locking feature 202 and the second locking feature 302 for representative purposes only. A person having ordinary knowledge in the art will appreciate that any modifications to the first locking feature 202 and the second locking feature 302 with implementation of the BTS 100 can be readily used since the present disclosure is not to be limited by any aspect of the first locking feature 202 and the second locking feature 302.

FIG. 3B illustrates a perspective view from below of the control housing 120. This illustrates the general design of the control housing 120 which needs to be compatible with area around the first locking feature 202 of the pump housing 112. Further, FIG. 3C illustrates a bottom perspective view of the control housing 120. The control unit 122 of the control housing 120 is provided near to the second locking feature 302 as illustrated by FIG. 3D, although other placements of the control unit 122 and the second locking feature 302 have been contemplated and are well within the scope of the present disclosure.

In an embodiment, the first locking feature 202 and the second locking feature 302 can be selected from one or more of a snap-fit coupling, or a push-fit coupling between the pump housing 112 and the control housing 120. Further, there can be any other locking arrangement, as known or used in the art, to couple the pump housing 112 and the control housing 120 and the present disclosure shall not be limited by choice of any of the locking feature.

FIG. 4 illustrates a cross-sectional view of the BTS 100. As best shown in this view, the control housing 120 includes at least a first compartment 402 which houses the power source. Further, the control housing 120 includes a second compartment 404 which houses the control unit 122 of the pump 110. FIG. 5 illustrates the control housing 120 and the pump 110 before assembly, in accordance with an embodiment of the present disclosure. The control housing 120 includes a pin 502 around the second locking feature 302 of the control housing 120. The pump 110, or more particularly, the pump housing 112 includes slots 504 around the first locking feature 202 of the pump 110. The pin 502 and the slots 504 are designed such that engagement of the pin 502 and the slots 504 allows coupling of the control housing 120 and the pump housing 112.

The pin 502 may be spring loaded. The pin 502 may move between an extended position (as illustrated) and a retracted position. The pin 502 may be inserted between the slots 504 in the retracted position, and then the pin 502 may extend afterwards to lock the control housing 120 with the pump housing 112. The present disclosure can be implemented with any or a combination of the first locking feature 202 and the second locking feature 302, and the pin 502 and the slots 504, however, it may be preferable to additionally have the pin 502 and the slots 504 along with the first locking feature 202 and the second locking feature 302 from consideration such as, but need not necessarily, weight or type or any other specification of the pump 110 and the control housing 120 of the BTS 100.
