[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] Example: Figure 1 and 2 As shown, the water intake device of this embodiment suitable for water accumulation in a gas discharge hole comprises a barrel body 1, a pressure plate 2 and a hollow support guide 3. The upper and lower ends of the barrel body 1 are both open, and a ring-shaped support plate 4 is horizontally fixed on the inner wall thereof. The pressure plate 2 is horizontally placed above the support plate 4, and the support guide 3 is arranged below the support plate 4 and connected to the lower end of the pressure plate 2. Under the action of external force, the pressure plate 2 can move upward until the support guide 3 abuts against the lower end of the support plate 4, or move downward until it is pressed on the upper end of the support plate 4 and seals and covers the inner hole of the support plate 4.

[0022] The water extraction operation is as follows:

[0023] The barrel body 1 is lowered into the well to be drained. Under the action of gravity, the barrel body 1 sinks, and the water in the well pushes up the pressure plate 2 and the support guide 3 to move upward to open the inner hole (inner ring hole) of the support plate 4. The lower end of the crystal barrel body 1 is open and enters the space above the support plate 4. After the barrel body 1 sinks to a certain height, the external force pulls the barrel body 1 upward. Due to the water pressure (water gravity) in the upper part of the barrel body 1, it will act on the upper part of the pressure plate 2, causing the pressure plate 2 and the support guide 3 to move downward. The water in the upper part of the support plate 4 can be discharged from the lower end of the barrel body 1 without tipping the barrel body 1. The operation is very simple and quick, and efficient drainage can be achieved.

[0024] Optimally, the barrel body 1 is a cylinder, and the support plate 4 is a circular ring plate coaxial with the barrel body 1 .

[0025] In this solution, the barrel body 1 is designed as a regular cylindrical shape, and the support plate 4 is also designed as a circular ring, which is more convenient to produce and process, and can ensure that water is smoothly accumulated from the inner ring of the support plate 4 to the upper space during the water intake process.

[0026] More preferably, the pressing plate 2 is a circular plate coaxially arranged with the barrel body 1 .

[0027] In this solution, the pressing plate 2 is also circular in design, which matches the shape of the supporting plate 4. The two can fit more closely and accurately, and the force can be better.

[0028] In this embodiment, the barrel body 1 is made of seamless steel pipe components with a length of 8m, an outer diameter of φ200mm, an inner diameter of φ180mm, a width of the support plate 4 of about 20mm, a maximum stroke of the pressure plate 2 moving up and down of about 200mm, and a height from the upper part of the support plate 4 to the upper open end of the barrel body 1 of about 7m.

[0029] In order to further improve the sealing performance of the cover between the pressing plate 2 and the supporting plate 4 , a sealing plate adapted to the inner hole of the supporting plate 4 can be provided at the lower part of the pressing plate 2 , and the diameter of the sealing plate is slightly smaller than the diameter of the inner hole of the supporting plate 4 .

[0030] As a preferred embodiment, the support guide member 3 is in contact with the inner wall of the barrel body 1 and can slide up and down relatively.

[0031] In this embodiment, the support guide 3 contacts the inner wall of the barrel body 1 and can slide up and down while in contact, ensuring that the pressure plate 2 maintains a straight line movement in the vertical direction and does not deviate left or right, so that at the end of water intake, it can smoothly descend to the upper part of the support plate 4 to seal and contact, thereby sealing and covering the inner hole of the support plate 4 to ensure the effectiveness of water intake.

[0032] As a preferred embodiment, the above-mentioned support guide member 3 includes a connecting rod 31 and at least three guide rods 32. The above-mentioned connecting rod 31 is vertically assembled in the middle of the above-mentioned pressure plate 2, and its lower end extends downward to the bottom of the above-mentioned support plate 4. At least three of the above-mentioned guide rods 32 are spaced around the lower end of the above-mentioned connecting rod 31, and one end of the above-mentioned guide rod 32 is respectively connected to the lower end of the above-mentioned connecting rod 31, and the other end thereof is respectively extended to contact the inner wall of the above-mentioned barrel body 1.

[0033] In this implementation, the supporting guide member 3 has a relatively simple and sophisticated structural design. It is connected and fixed to the pressure plate 2 by a connecting rod 31, and then cooperates with a plurality of guide rods 32 to contact the inner wall of the barrel body 1 in various directions (support and guide), ensuring that the pressure plate 2 can maintain linear movement during the up and down movement, that is, the pressure plate 2 and the support plate 4 will not be misaligned when they are in contact and sealed with each other, ensuring that the two are in close contact to achieve effective water storage.

[0034] Optimally, a roller 321 is mounted on the other end of the guide rod 32 and is in rolling contact with the inner wall of the barrel body 1 .

[0035] In this embodiment, the end of the guide rod 32 is rolled with the inner wall of the barrel body 1 through the roller 321, which effectively reduces the friction between the two.

[0036] More specifically, grooves corresponding to the rollers 321 are vertically arranged on the inner wall of the barrel body 1 , and the rollers 321 extend into the corresponding grooves respectively and roll in contact with each other.

[0037] In this solution, through the design of the groove, the roller 321 can only roll up and down in the groove and will not deviate from the position of the groove. In other words, the support guide 3 and the pressure plate 2 will move up and down without skewing or flipping, ensuring that the pressure plate 2 and the support plate 4 are well sealed when in contact with each other.

[0038] As a preferred embodiment, a flexible sealing ring is provided at the lower end of the edge of the pressing plate 2 for sealingly contacting the upper portion of the supporting plate 4 , or a flexible sealing layer is provided on the lower surface of the pressing plate 2 .

[0039] In this embodiment, the design of the sealing ring enables the support plate 4 to be more tightly fitted with the pressure plate 2 when in contact and sealing under the action of external force (gravity), and the sealing performance is further improved.

[0040] Of course, if the sealing ring is annular, a groove matching the sealing ring can be provided at the upper end of the support plate 4, so that when the support plate 4 is in sealing contact with the pressure plate 2, the sealing ring can be embedded in the groove, and the sealing performance is very good.

[0041] As a preferred embodiment, the upper end of the connecting rod 31 is set as a screw section and passes through the middle part of the pressure plate 2. The first upper nut and the first lower nut are screwed and installed on the screw section at the upper end of the connecting rod 31. The first upper nut and the first lower nut are respectively abutted against the upper and lower ends of the middle part of the pressure plate 2.

[0042] The design of the above solution allows the connecting rod 31 and the pressing plate 2 to be easily assembled and disassembled, which is beneficial to daily maintenance and repair operations.

[0043] It should be noted that: by adopting this solution, the tightness of the contact between the pressing plate 2 and the supporting plate 4 can be adjusted by adjusting the relative positions of the first upper nut, the first lower nut and the connecting rod 31 .

[0044] As a preferred embodiment, the lower end of the connecting rod 31 is provided with a screw section, and a second upper nut and a second lower nut are screwed and installed on the screw section at the lower end, and an annular connecting portion sleeved on the lower end of the connecting rod 31 is sandwiched between the second upper nut and the second lower nut, and one end of the guide rod 32 is respectively connected and fixed to the outer periphery of the annular connecting portion.

[0045] In this embodiment, the connecting rod 31 and the guide rod 32 are matched with each other in a detachable structure, which is convenient for subsequent disassembly and assembly and is beneficial to daily maintenance and repair operations.

[0046] It should be noted that: by adopting this solution, the tightness of the contact between the pressing plate 2 and the supporting plate 4 can be adjusted by adjusting the relative positions of the second upper nut and the second lower nut and the connecting rod 31 .

[0047] As a preferred embodiment, it also includes a lifting mechanism, which is connected to the barrel body 1 and is used to operate the barrel body 1 to lift and lower in the well.

[0048] In this solution, the barrel body 1 can be lowered into or out of the well through the lifting mechanism.

[0049] The lifting mechanism can adopt a conventional winch, which can be erected above the wellhead.
