Description

{DEEP WELL COVER DEVICE}

More particularly, the present invention relates to a groundwater-tight upper protection hole capable of mechanically coupling a discharge pipe head and a water supply pipe through screw tightening even in a narrow casing diameter.

Generally, the groundwater pumping apparatus is constructed, for example, by inserting a pipe-shaped outer casing into a drilling hole to excavate rocks of an earth surface to a depth of not more than a submergence by using an excavator of a predetermined thickness and then preventing inflow of surface water A grouting method in which the liquid is injected outside the outer casing and the outer casing is fixed to the ground is used and a plurality of pipes are connected to each other in the longitudinal direction to extend the water pipe to the deep well, The underwater pump is mounted and the groundwater is pumped up by the operation of the upper and lower level switches installed at a predetermined position.

As we all know, groundwater refers to groundwater that fills or flows between gaps in rocks or underground strata. In recent years, various pollutants are mixed with groundwater, and the quality of groundwater is deteriorating.

In addition, since the ground cover has been kept open until now, when the ground is used as an insecticide or a flood, the contaminated surface water flows into the inner part of the groundwater without any resistance, and the groundwater is seriously polluted I was forced to throw away.

In order to overcome this problem, the present inventor has developed various inventions and designs that can completely seal the upper part of the groundwater aquifer, thereby improving the functions of components of the groundwater aquarium and fundamentally preventing inflow of pollutants from the surface Technology, methods, and products.

 It is a patented protection device for groundwater protection with complete hermeticity. Patent No. 0330508 (Groundwater vacuum pumping device), Patent No. 0330508 (Protection device for ground water), Utility Model Registration No. 0105323 (Groundwater vacuum pumping device) Registered Utility Model No. 0176973 (Groundwater Pumping System), Registered Utility Model No. 0219401 (Enclosed Covering System for Adjusting the Height of Connected Pipes), Registered Utility Model No. 0176308 (Underground Aqueduct Enclosed Cover) and Registered Utility Model 0294642 (Cover for Underwater Watershed) have been proposed.

The conventional airtight type upper protection hole is composed of a cylindrical case having upper and lower openings and a lid which is coupled to an upper opening of the case through a plurality of bolts to seal the inside of the case, thereby protecting the ambulatory facility. The case of the upper protection ball is provided with a port for connection (withdrawal) of the water supply pipe and the power cable.

  The most difficult problem in the field application of the hermetically sealed upper protection technology was that the discharge hole connected with the water pipe inside the sealed upper protection hole and the water pipe outside the sealed upper protection hole using a hand in a space of about 250 mm in diameter And the connected water supply was strongly coupled without leakage even at high pressure. In the Utility Model Registration No. 0369260 (Registered Utility Model Name; a discharge port and a water supply hole coupling device for underground water distillation), the present invention uses a screw fastening method to press a wedge against a tongue portion of a pumping head to connect a discharge port to a water supply port . However, this design had a difficulty in necessarily installing the water meter in the vertical direction. In addition, the inventor of the present invention invented an enclosed upper protection hole in which a pocket was formed through a patent application No. 10-2005-0076696 (patent name: an underground water depth milling upper protection device forming a water supply pipe pocket) It was succeeded to develop a product that can be combined with the piping structure while ensuring space for installation. However, in this case, the connection of the piping is made by the use of the camark coupling (aka hose capping) It is necessary to have a forward and backward separation distance of 20 mm or more at the time of engagement and disconnection. As a result, a corrugated pipe must be used at the top of the water pipe to assist the forward and backward movement of the discharge port. The inner size of the upper protection hole must be increased and as a result, the installation space of the device is widened Having problems with inconveniences and increasing the number of device components

there was.

In addition, in the conventional screw tightening method, a support plate is provided inside the casing, and the discharge port head is slid from the upper part of the support plate to connect the discharge port and the water supply port. Thus, complexity of the apparatus and deterioration of sliding performance due to the load of the underwater pump It is inconvenient to secure a diameter of at least 250 mm or more so that the economical efficiency is low.

In some products, there is a technique of coupling a discharge port and a water supply port due to the weight of an underwater pump and a water pipe, instead of a mechanical coupling using a screw tightening or the like. However, there is a problem that it is difficult to ensure watertightness due to a water shock during operation.

Therefore, it is required to develop a structure capable of constructing an economical device while securing a high watertightness through a mechanical screw connection even in a casing of about 150 mm.

For example, As shown in FIG. 8, of course, inclined surfaces 52a and 20a corresponding to the inclined surfaces 53a of the wedge 53 are formed in the push rod 52 and the discharge pipe head 20.

Particularly, the front end portion of the push rod 52 contacting with the rear guide 40 has a feature that the pressing force applied to the discharge tube head 20 in the case of hemispherical or conical shape is uniformly distributed in the center direction .

The wedge (53) is lifted by the wedge adjusting bolt (55).

The wedge adjusting bolt 55 is connected to the wedge 53 at the bottom and is screwed to the nut formed in the pushing rod housing 51 through the thread of the peripheral portion and moves the wedge 53 downward or upward according to the rotating direction.

It is necessary to lock the discharge pipe head 20 if maintenance or replacement of the materials including the discharge pipe head 20 does not occur after the discharge pipe head 20 is installed in a watertight manner through the wedge 53, In the present invention, as shown in FIG. 9, the wedge adjusting bolt 55 is restrained by the locking hole 56 so as not to rotate, thereby maintaining the installed state of the discharge pipe head 20. [ The locking member 56 is supported by the compression bar housing 51 and is fitted to the head of the wedge adjusting bolt 55 so as not to rotate the wedge adjusting bolt 55. For example, And a housing support portion 56b which is connected to the lock cap 56a and is supported by the compression bar housing 51. The lock cap 56a is provided with a lock cap 56a, The housing support portion 56b is rotatably connected to the push rod housing 51 through a hinge while being connected to one side of the lock cap 56a. The housing support portion 56b is extended from both sides of the lock cap 56a, Or the like, or the like.
