The gate pump of the present invention is mounted on the hydrologic main body of the integral water type pump and operates the water gate while opening and closing the water gate to adjust the water level by pushing and pulling the water.

Generally, the gate is constituted by an opening, and the gate pump is inserted into the opening to form a through hole.

Further, a fastening flange on the side of the water gate is formed on the outer periphery of the water passage, and the fastening flange on the side of the water gate and the fastening flange on the side of the gate pump are tightly fixed to the water gate through screw tightening or riveting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

5 to 7, the gate pump of the present invention, which is provided in a pump-integrated type gate, includes a main body 10, a motor 20, and a suction force generator 30.

The main body portion 10 includes:

A pump body 11, a fastening flange 12, a suction port 13, and a discharge port 14.

The pump main body 11 is made of metal such as steel so as to have a drum shape with front and rear openings and housing the motor part 20 therein and having sufficient rigidity to withstand pressure and impact desirable.

The fastening flange 12 is used to fasten the pump body 11 to the water gate and is screwed or screwed into a screw fastening hole formed by drilling a hole at a predetermined interval in the fastening flange 12 And tightly fixed to the tightening flange 12 on the side of the water gate.

The suction port 13 and the discharge port 14 are located at the front and rear sides of the pump body 11 so as to be sucked from the suction port 13 and discharged from the discharge port 14, Of water to another location.

The motor section (20)

An underwater motor 21, a motor strut 22 and an impeller 23,

The submersible motor 21 should be completely sealed so as to be immersed in water so as not to interfere with operation, and should be made to have a sufficient impact force so as not to malfunction in an environment of rough flow rate. In addition, the facility should be equipped so that it does not interfere with receiving power from the outside.

The motor strut 22 serves as a support for fixing the submersible motor 21 to the main body 10. If the underwater motor 21 rotates at a high speed, if it is not fixed properly, it is immediately predicted that a strong vibration will be generated and this vibration will lead to a failure of the gate pump. Since the underwater motor 21 is disposed along the length of the pump body 11 and the forward portion of the underwater motor 21 is protruded to the front of the pump body 11, And is formed on the waist or tail side of the submersible motor 21.

The impeller 23 is connected to the rear of the submersible motor 21 so as to rotate, and converts the electric power of the submersible motor 21 into a flow of a physical fluid.

On the other hand, in the example of FIGS. 3 and 4, which is a background of the present invention, the outer periphery of the end of the impeller is in contact with the wear ring. The wear ring is inserted into the pump body to prevent water from leaking from the outer periphery of the impeller or preventing the water from flowing backward.

However, the water passing through the gates is turbid and contains a lot of pollutants. Therefore, foreign matter often gets caught between the impeller and the wearer. In this case, normal rotation of the underwater motor becomes impossible, and a strong load is applied to the electric power system, so that it can be connected to a large failure. 3 and FIG. 4 are intended to correct this point, and the wearer is divided so that elasticity such as a spring or the like can be used to elastically cope with foreign matter such as impurities.

However, since friction force is generated with the impeller using the wear ring, and the construction is complicated by the division of the wear ring, and a large number of springs are used, not only the construction troubles but also the gate pump are operated so as to be immersed in water, Durability is poor.

The suction force generating unit 30 according to the present invention is intended to overcome the disadvantages of the background art described above. The suction force generating unit 30 is constructed by utilizing the Bernoulli's theorem widely known in the field of physics and fluid mechanics will be.

Bernoulli theorem, for example, lets air flow through a tube of varying thickness and connects a glass tube that goes below the thickness. When we observe the height of water in a thin glass tube, the height of the water column connected to the thicker side is lowered, and the height of the water column connected to the thinner side is higher. When fluid flows at the same height, the velocity of the fluid increases as it flows through the narrow passages and decreases as it flows through the wide passages. According to Bernoulli's theorem, as the fluid velocity increases, the pressure inside the fluid decreases, and conversely as the velocity decreases, the internal pressure increases. As the pressure increases, the height of the water column decreases as the water column in the glass tube is pressed harder. As the pressure decreases, the water column in the glass tube presses weaker, increasing the height of the water column.

5 to 8, the suction force generating unit 30 includes:

The fluid separation membrane 31, the fluid separation membrane strut 32, the fluid separation membrane inlet 33, and the fluid separation membrane outlet 34.

The fluid separation membrane 31 is disposed close to the rear of the outer peripheral side of the end of the impeller 23. Its shape takes the shape of a ring made by rolling the face of a wing. And is spaced apart from the inner circumference (inner circumference) of the pump body 11 by a predetermined distance.

The fluid separation membrane strut 32 functions to hold and fix the fluid separation membrane 31 so as to maintain the disposed state and extends from the outer circumference of the fluid separation membrane 31 to the inner circumference of the pump body 11 It is a kind of pole or plate fixing the two. At the same time, the fluid separation membrane strut 32 can also serve as a partition for horizontally dividing the channel 35. In this case, it is preferable to take the form of the partition plate, because the water level, that is, the water level, can be differentiated from the other channels which do not occupy water. In the case of dividing the water channel horizontally by taking the form of the partition plate, it is advantageous to keep the pressure of low pressure separately as much as the part immersed in water even when the water channel 35 which is not immersed partially occurs.

The fluid separation membrane inlet 33 and the fluid separation membrane exit 34 are respectively located at the front and rear of the fluid separation membrane 31 so that water is sucked from the front fluid separation membrane inlet 33, 34). Strictly speaking, the water on the side of the fluid separation membrane inlet 33 is pulled out by a force attracted from the fluid separation membrane outlet 34.

7, 8 and 9, and more specifically,

When the impeller 23 is rotated by the power of the underwater motor 21, water is sucked from the suction port 13 and discharged to the discharge port 14. At this time, a low pressure 30b is generated at the rear of the fluid separation membrane 31 due to the flow velocity of water. The low pressure 30b is transmitted to the outer periphery of the impeller 23 through the water passage 35 in the fluid separation membrane 31, The water present in the interval d1 between the inner circumference 31a of the main body 11 is sucked 30c to generate a flow velocity. Therefore, even if the impeller 23 and the pump main body 11 are not in contact with each other and there is a gap d1 or there is no wear ring, a part where the flow of water stops partially does not occur or the back flow does not occur.

Since the impeller 23 does not physically contact the inside of the pump or the wear ring, there is no friction so that the energy efficiency is high, the life can be prolonged, and troubles caused by foreign substances are eliminated.

9, the separation distance d3 of the fluid separation membrane outlet 34 may be set to be larger than the separation distance d2 of the fluid separation membrane inlet 33 in order to enhance the suction force due to the generation of the low pressure 30b have. The attraction force at the inlet side of the fluid separation membrane 31 becomes larger by the difference in the separation distance.

In the example shown in Fig. 10A, the fluid separation membrane 31 is formed horizontally as viewed from the front. This is because the water flowing into the gates does not always lock the entire gate pump as shown in FIG. 10B. Only the bottom of the middle or gate pump can be locked.

At this time, if the fluid separation membrane 31 is formed in a horizontal state as viewed from the front, at least the water-immersed layer is not leaked to the other portion of the low-pressure force and the suction action can be faithfully performed.

In addition, since the bottom surface of the pump gate is mostly immersed in water, the gap between the fluid separation membranes 31 may be increased. However, since the upper surface of the pump gate may not be immersed or immersed frequently depending on the water level, it is preferable that the interval between the fluid separation membranes 31 on the upper surface side is made smaller and smaller so as to adapt even to minute differences.

The configuration of the present invention can also be applied to an underwater pump or a ventilator used in other places than the pump gate.
