[0033] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] The present invention provides an underwater pipe port filter screen and sealing plate device installed in an automatically coupled manner, wherein a water intake pipe is horizontally penetrated and arranged on the side wall of a basement, and comprises:

[0035] A guide rod assembly is arranged beside the side wall, one end of the guide rod assembly is located above the water surface, and the other end of the guide rod assembly is arranged below the water intake of the water intake pipe;

[0036] The coupling frame is coupled to the water intake, and the coupling frame includes a horizontal portion and a vertical portion. One end of the vertical portion is vertically connected to the middle of the horizontal portion, and one end of the horizontal portion moves along the length direction of the guide rod assembly. When the coupling frame is firmly connected to the water intake, the vertical portion aligns the filter assembly or the sealing plate with the water intake for communication;

[0037] The pressure rod assembly has one end arranged on the ground. The pressure rod assembly comprises a pressure rod arranged in the vertical direction. When the pressure rod abuts against the other end of the horizontal part, the pressure rod applies a vertical downward force to the coupling frame.

[0038] Specifically, the device is arranged at the junction of the side wall and the ground of the basement, and the guide rod assembly is arranged on the side wall in the vertical direction, wherein the guide rod brackets in the guide rod assembly are respectively arranged above the water surface and near the water intake, and a guide rod bracket is also required to be arranged below the water intake, so that the guide rod bracket can fix the guide rod within the up and down lifting area of ​​the entire coupling frame, so that the guide rod can realize the motion guiding function of the coupling frame; the coupling frame is composed of two structures, a horizontal part and a vertical part, a guide hole matching the guide rod is arranged at one end of the horizontal part, a wedge block matching the water intake profile is arranged at the middle section of the horizontal part, and a mounting hole connected with the pressure rod is arranged at the other end of the horizontal part, and the vertical part needs to maintain a mutually perpendicular positional relationship with the horizontal part, and a connecting hole is also arranged in the vertical part. When the pressure rod applies downward pressure to the coupling frame, the coupling frame fits with the pipe mouth of the water intake. In this way, the connecting hole of the vertical part can be aligned with the water intake, so that the filter assembly or the sealing plate connected on the vertical part can be connected to the water intake correspondingly, so that the drainage can be filtered or blocked; the pressure rod assembly is arranged on the ground, and the pressure rod assembly extends horizontally to the top of the coupling frame. In this way, when the pressure rod bracket is firmly installed on the ground, the pressure rod can be inserted into the pressure rod bracket in the vertical direction, so that the lower end of the pressure rod is pressed on the horizontal part of the coupling frame, so that the wedge block of the coupling frame fits more tightly and stably with the pipe mouth of the water intake, so that the connecting hole of the vertical part can be accurately connected with the water intake, and when the filter assembly or the sealing plate needs to be removed from the water intake, the pressure rod bracket can be disconnected from the ground, and then the handle can be lifted up and taken out together with the pressure rod assembly, so that the pressure rod and the coupling frame are separated from the water intake, and the removal of the filter assembly and the sealing plate can be completed without the participation of divers.

[0039] Optionally, the guide rod assembly includes at least two guide rod brackets and a guide rod, wherein the guide rod brackets are respectively arranged above the water surface and below the water intake, and the guide rod is arranged in a vertical direction and connected to the guide rod brackets.

[0040] Optionally, two guide rods are provided, and two notches are symmetrically provided at one end of the horizontal portion, and the outer peripheral surface of the guide rod is conformed to the inner wall surface of the notch, and the guide rod clamps and fixes the coupling frame from both sides.

[0041] Specifically, there can be multiple guide rod brackets in the guide rod assembly, but guide rod brackets must be provided above the water surface and below the water intake pipe, so that the guide rod can be stably connected above the water surface and below the water intake pipe, so that the guide rod can accurately guide the coupling frame; two guide rods need to be provided, and a notch is provided at the position where the coupling frame is connected to the guide rod, and the two sides of the coupling frame are clamped and fixed by the two guide rods, so that the moving direction of the coupling frame is always subject to limit control, ensuring that when the coupling frame moves downward to the pipe mouth of the water intake, the wedge block of the coupling frame is aligned with the wedge groove of the water intake, so that the connecting hole of the vertical part of the coupling frame can be accurately connected with the water intake; when the coupling frame needs to be removed from the water intake, the guide rod can limit the upward movement direction of the coupling frame to prevent the coupling frame from rotating and tilting during the ascent, causing the coupling frame and the water intake to interfere with each other, thereby preventing the filter assembly and the sealing plate from being removed.

[0042] Optionally, a wedge-shaped groove is provided at the pipe mouth of the water intake along the circumferential direction, and a wedge-shaped block matching with the wedge-shaped groove is provided at the angle between the horizontal portion and the vertical portion.

[0043] Optionally, a sealing ring is provided between one side of the vertical portion and the water intake, the filter assembly and the sealing plate are connected to the other side of the vertical portion by bolts, and a connecting hole with the same aperture as the water intake is provided on the vertical portion.

[0044] Specifically, in order to enable the coupling frame to accurately connect the connecting hole of the vertical part with the water intake under the guidance of the guide rod and the downward compression of the pressure rod, a wedge-shaped groove is provided on the pipe mouth of the water intake, and a wedge-shaped block is also provided on the lower side of the horizontal part. When the pressure rod moves downward to compress the coupling frame downward, the two guide rods clamp and fix the coupling frame, so that the coupling frame can only move downward in the vertical direction. In this way, the wedge block can accurately enter the wedge-shaped groove, and the wedge block is completely fitted with the profile of the wedge groove. When the coupling frame can no longer move downward, the connecting hole on the vertical part of the coupling frame can be accurately connected with the water intake of the water intake pipe. In order to ensure that all water in the water intake pipe enters the filter assembly through the connecting hole for filtration, a sealing ring is provided on the side of the connecting hole facing the water intake, so that after the coupling frame is installed in place, the sealing ring can be provided between the connecting hole and the water intake to improve the sealing of the connection.

[0045] Optionally, the filter screen assembly is a filter screen cylinder, a plurality of long strip punching holes are arranged on the circumferential surface of the filter screen cylinder, and the material of the filter screen cylinder is stainless steel.

[0046] Specifically, the filter assembly adopts a filter screen cylinder with long strip punched holes, and the size of the screen cylinder can be adjusted according to actual needs, thereby reducing the loss of hydraulic power.

[0047] Optionally, the pressure rod assembly comprises:

[0048] A pressure rod bracket, one end of which is connected to the ground, and the other end of which is clamped with a pressure plate;

[0049] A nut is arranged on the pressure plate, a pressure rod passes through the pressure plate and the pressure rod bracket and is threadedly connected to the nut, and an extrusion plate is arranged at one end of the pressure rod located at the lower side of the pressure rod bracket. When the lower side of the extrusion plate fits with the horizontal part, the vertical part cooperates with the water intake.

[0050] Specifically, the pressure rod assembly includes a pressure rod bracket, a pressure plate, a nut and a pressure rod. First, the pressure plate and the nut are clamped and fixed on the pressure rod bracket, and then the pressure rod is passed through the pressure plate bracket, the pressure plate and the nut to achieve a threaded connection between the pressure rod and the nut. Next, the pressure rod bracket is installed on the ground. During the installation process, the position of the pressure rod is adjusted to ensure that the pressure rod is located above the coupling frame. After the pressure rod bracket is fixed on the ground, the nut is turned to move the pressure rod downward until the extrusion plate at the lower end of the pressure rod is against the horizontal part of the coupling frame. When the nut cannot be rotated, it means that the coupling frame and the water intake port have been installed in place, and the water intake port and the filter assembly or the sealing plate have been accurately connected.

[0051] Optionally, a detachable handle is provided at one end of the pressure rod located on the upper side of the pressure rod bracket.

[0052] Specifically, the upper end of the pressure rod can be detachably connected with a handle. When the pressure rod is installed on the pressure plate bracket, the handle has not been installed on the pressure rod. When the filter assembly or the sealing plate needs to be removed, the handle needs to be installed on the pressure rod. As long as the pressure rod bracket is removed from the ground in advance, the handle can be lifted, and the filter assembly or the sealing plate together with the coupling frame can be removed from the water intake. It should be noted that an expansion buckle is provided on the extrusion plate at the lower end of the pressure rod, and a clamping hole is provided on the horizontal part of the coupling frame at the position corresponding to the expansion buckle. During the installation of the filter assembly or the sealing plate, the pressure rod drives the extrusion plate to move downward, so that the extrusion plate abuts against the coupling frame. During the abutment process, the expansion buckle is inserted into the clamping hole, so that the pressure rod is connected to the coupling frame. When the filter assembly or the sealing plate needs to be removed, the pressure rod assembly can be pulled up by the handle, so that the pressure rod and the coupling frame can move upward together. In this way, the disassembly work can be achieved without the need for divers to go into the water, reducing the difficulty of work and safety risks.

[0053] Optionally, the filter assembly and the sealing plate are detachably connected to the vertical portion.

[0054] Specifically, when it is necessary to filter the water or seal the water intake, it is only necessary to alternately install the filter assembly and the sealing plate on the connecting hole of the coupling frame, without replacing the entire device, and the operation process is time-saving and labor-saving.

One end of the vertical portion 9 is vertically connected to the lower middle portion of the horizontal portion 7. The left end of the horizontal portion 8 moves along the length direction of the guide rod assembly 4. When the coupling frame 7 is firmly connected to the water inlet 6, the vertical portion 9 aligns the filter assembly 10 or the sealing plate 11 with the water inlet 6 for communication;

[0059] The left end of the pressure rod assembly 12 is arranged on the ground 13. The pressure rod assembly 12 includes a pressure rod 14 arranged along the vertical direction. When the pressure rod 14 abuts against the upper side of the right end of the horizontal part 8, the pressure rod 14 applies a vertical downward force to the coupling frame 7.

[0060] In this embodiment, the guide rod assembly 4 includes two guide rod brackets 15 and a guide rod 16 . The guide rod brackets 15 are respectively above the water surface 5 and below the water intake 6 . The guide rod 16 is arranged in the vertical direction and connected to the guide rod brackets 15 .

[0061] In this embodiment, two guide rods 16 are provided, and two notches 17 are symmetrically provided at the left end of the horizontal portion 8. The outer peripheral surface of the guide rod 16 is conformed to the inner wall surface of the notch 17, and the guide rod 16 clamps and fixes the coupling frame 7 from both sides.

[0062] In this embodiment, a wedge-shaped groove is provided above the pipe opening of the water intake 6, and a wedge-shaped block 18 matching the wedge-shaped groove is provided at the angle between the horizontal portion 8 and the vertical portion 9.

[0063] In this embodiment, a sealing ring 19 is provided between one side of the vertical portion 9 and the water intake 6, the filter assembly 10 and the sealing plate 11 are connected to the other side of the vertical portion 9 by bolts, and a connecting hole with the same aperture as the water intake 6 is provided on the vertical portion 9.

[0064] In this embodiment, the filter assembly 10 is a filter screen cylinder, a plurality of long strip punching holes are arranged on the circumferential surface of the filter screen cylinder, and the material of the filter screen cylinder is stainless steel.

[0065] In this embodiment, the pressure rod assembly 12 includes:

[0066] The left end of the pressure rod bracket 20 is connected to the ground 13, and the right end of the pressure rod bracket 20 is clamped with a pressure plate 21;

[0067] The nut 22 is set on the pressure plate 21, the pressure rod 14 passes through the pressure plate 21 and the pressure rod bracket 20 and is threadedly connected with the nut 22, and an extrusion plate 23 is set at one end of the pressure rod 14 located at the lower side of the pressure rod bracket 20. When the lower side of the extrusion plate 23 is in contact with the horizontal part 8, the vertical part 9 cooperates with the water intake 6.

[0069] In this embodiment, the filter assembly 10 and the sealing plate 11 are detachably connected to the vertical portion 9 .

[0070] In summary, when the device connects the filter assembly 10 with the water intake 6, the guide rod bracket 15 is first installed on the side wall 3, and then the coupling frame 7 is placed on the two guide rod 16 brackets. Next, the coupling frame 7 connected with the filter assembly 10 is put into the water, and the coupling frame 7 moves downward along the restricted direction of the guide rod assembly 4, and then the pressure rod assembly 12 is installed on the ground 13. The pressure rod 14 applies a downward force to the coupling frame 7, and at the same time, the nut 22 is rotated to apply a downward force to the coupling frame 7, so that the wedge block 18 of the coupling frame 7 is embedded in the wedge groove. When the pressure rod 14 can no longer move downward, the vertical portion 9 is completely in contact with the water intake 6, and the filter assembly 10 is precisely docked with the water intake 6, so that the outlet water is filtered. When the filter assembly 10 needs to be removed from the water intake 6, the pressure rod bracket 20 needs to be disassembled and separated from the ground 13 first, and then the handle 24 needs to be installed on the upper end of the pressure rod 14, and finally the pressure rod assembly 12 together with the coupling frame 7 can be removed from the water intake 6 by lifting the handle 24 upward, so that the diver does not need to perform underwater operations. In addition, the disassembly and assembly process of the sealing plate 11 and the water intake 6 is exactly the same as the operation of the filter assembly 10, and the filter assembly 10 only needs to be replaced by the sealing plate 11 and connected to the connecting hole of the vertical portion 9.
