Description

PUMP MOUNTED GATE

The present invention relates to a pump mounted gate and, more particularly, relates to a pump mounted gate capable of dispersing the concentrated load of the pump acting thereto, dispersing the vertical load thereto to the front and rear sides thereof, eliminating the moment caused by the downward load acting on its body, simply adjusting the distance between a guide plate and a travelling roller, and also blocking the vibration occurred during pump-operating to the guide frame structures of watercourse.

Generally, a various purpose gate, which is provided at the termination of the water channels such as a river or the like in the cross-sectional direction, have one of functions including water managing role to discharge interior water toward outside and block count-flow of exterior water toward inside, water utilizing role to utilize interior water as water resources and water discharging role to discharge interior water toward outside forcibly when the level of the exterior water goes higher than that of interior water.

Firstly, considering the water managing role of the conventional gate, which is installed at the termination of the water channel of river, levee, embankment, etc., it kept usually opened to discharge interior water of upper stream naturally toward outside by gravity flow, while it has been lifted, it is required to close the water channel thereby so as to block exterior water from being inflow toward inside when the exterior water level goes higher than the predesignated level by the increasing amount of rainfall according to the localized heavy rain, rainy season, typhoon, etc.

At this time, although inflow of the exterior water toward inside could be blocked by closing of the gate, but there happens some problems of which houses or farmland, as had not been provided any compulsive drainage facilities, may be inundated to suffer a serious damage as the level of the interior water increased in accordance with the continuation of rain- fall because interior water cannot be discharged by gravity flow.

Therefore, although it is necessary to establish a drainage pump station or a storm water pumping station for prevention of house or farmland in low-lying districts from inundation, but it is hard to construct the storm water pump station in adequate place because of not only a large scale budget required for purchasing land to build a storm water pump station and a sump reservoir, constructing a storm water pump station, buying a mechanical and electrical & instrumentation, overhead bridge crane and auxiliary facilities, paying for mechanical and electrical facilities construction etc., but also a NYMBY phenomenon of residents for dislike of offensive odor from the sump pit of the storm water pump station.

Especially, it is hardly realized to construct a storm water pump station in necessity because not only there is few place sized enough to construct the storm water pump station in the cities located nearby seashore or in low-lying and congestive district around the watercourse of the city having a big river owing to the mature of cities but also there is few plan established by the central government and/or the local government authorities due to land owner's very high compensation claim.

Accordingly, problem that observes a loss of lives and huge property damage have been repeated year and year since inundation of the low-lying district is inevitable when the level of exterior water rises abruptly and that of interior water rises concurrently as typhoon, which occurs every year, sudden, unexpected and localized downpour, which occurs frequently these days, or rainy season, etc.

To solve these problems in water management and compulsive discharge, improved floodgates comprising an opening portion formed in its main gate leaf and a pump being equipped with the opening portion integrally are disclosed through Republic of Korea utility model registered number 20-0361664 (floodgate having counter-flow preventing valve and submerged pump, hereinafter refers to as the first utility model), Republic of Korea registered patent number 10-0497044 (apparatus and operating method for pump mounted gate, hereinafter refers to as the first invention), Republic of Korea publicized patent application number 10-2005-0104220(pump mounted gate, hereinafter refers to as the second invention), Republic of Korea registered patent number 10-0563369 (floodgate for drainage, hereinafter refers to as the third invention), Republic of Korea registered utility model number 20-0390498 (draining device of floodgate, hereinafter refers to as the second utility model), Republic of Korea registered utility model number 20-0403219 (draining device of floodgate, hereinafter refers to as the third utility model).

Those conventional floodgates are common in that an opening portion 12 are formed in the gate leaf 11 in the shape of the square plate and a pump 30 is mounted at the opening portion 12 integrally, and interior water is discharged forcibly toward outside by driving the pump 30 while the gate leaf 11 is closed, as shown in FIG. 1 and 2.

That is, a floodgate, an affixing plate and a pump referred in the first utility model; a gate leaf, an opening portion and a pump referred in the first invention; a gate leaf, an opening portion and a pump referred in the second invention; a gate leaf and a drainage pump referred in the third invention; a gate leaf and a drainage pump referred in the second utility model; a gate leaf and a drainage pump referred in the third utility model are corresponding to all the elements, respectively or partly, of the square plate type gate leaf 11, the opening portion 12 formed on the gate leaf 11, the pump 30 mounted on the opening portion 12.

Those conventional pump mounted gates, as shown in Figs. 1 and 2, prevent the exterior water from flowing into interior water by a counter-flow preventing valve 32 as a flap valve, and discharge the interior water forcibly toward the exterior water by the pump 30.

In those conventional gates, as shown in Figs. 1 and 2, the gate 1 integrated with the pump 30 is opened usually to discharge by gravity whereas the integrated pump 30 is driven to discharge the interior water forcibly after the gate 1 is closed when the level of the exterior water rises.

However, those conventional gates have some problems as given in the following rationale:

1) the gate becomes damaged or the pump 30 cannot be driven by severe vibration resulted by a resonance, which occurs in case that the difference in frequency between natural frequency of the gate in lower order modes(1st through 5th) and the frequency of the integrated pump 30 in rotation (f=rpm/60) is small; (here, the natural frequency of the gate is calculated in consideration of the load of the pump as a concentrated load since the rigidity (k) or mass (m) of the gate leaf made of a thin plate are much less than those of the pump);

2) the gate cannot be closed adequately, the seal rubber the lower sealing surface of the gate can be easily broken, and also sealing function between the gate leaf 11 and guide frame 17 cannot be maintained by acting of the moment (M=F1xL), which is generated by F1 multiply horizontal distance L (about 800mm) from the connecting rod 16 to the lower sealing surface of the guide frame 17 and induces the pump mounted gate 1 slanted toward the rear side thereof (which is the opposite side against the side having a seal rubber and referred to as a rear side of the gate, hereinafter), because downward load F1 generated by an opening/closing operator 20 presses down the connecting rod bracket 15, which is a connecting portion between the gate leaf 11 and the opening/closing operator 20, downward in closing operation of the gate 1, as shown in Fig. 2, in the conventional pump mounted gate;

3) stability of the physical behavior of the conventional pump mounted gate is reduced due to the vibration occurred in high speed operation of the pump 30 because the concentrated load acting on just one point of the gate leaf 11 despite of horizontally extruded length of the pump 30, for the pump 30 is connected at the mounting flange 31 provided at the opening portion 12 of the rear side of the gate leaf 11 when the pump is connected to the gate leaf 11, as shown in Fig. 2;

4) there is a necessity to adjust and reinstall the wedge 57 after removing itself so as to adjust the contact on spot because, in the conventional pump mounted gate, a wedge 57 should be installed by means of welding on the spot to the corresponding point to which the travelling roller 13 is to be safely settled when the gate 1 is closed to operate the pump 30 and it is difficult to observe properly whether the travelling roller 13 is safely settled to the wedge 57, and further, the contact between the wedge 57 and the travelling roller 13 gets loose while operation of gate by the load generated by water pressure acting on the gate leaf 11 in horizontal direction once the wedge 57 is installed; and

5) in the conventional pump mounted gate, the vibration occurred in the operation of the pump 30 is delivered directly to the gate guide structure because the wedge 57 and the travelling roller 13 is contacted by wedge engagement to each other as they are made of metal (e.g. stainless steel) with high rigidity. Thus, there is a problem that influence caused by the vibration hinders the establishment of the pump mounted gate despite of various advantages achieved by the installation of the pump mounted gate.
