DETAILED DESCRIPTION

[0027] The present application will be further described below in conjunction with the drawings and specific embodiments. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation of the present application. The specific structural and functional details disclosed herein are only used to describe the example embodiments of the present application. However, the present application can be embodied in many alternative forms, and should not be understood as limited in the embodiments described herein.

[0028] As shown in Figure 1 , Figure 2 , Figure 1 The structural schematic diagram of the well head device provided by the embodiment of the present application is shown in the figure. Figure 2 The structural schematic diagram of the well head device provided by the embodiment of the present application is shown in the figure.

[0029] As shown in Figure 1 , Figure 2As shown, the main body 100 is provided with a through working channel, and the top of the main body 100 is provided with a working opening. The inner wall of the main body 100 is provided with a mounting step 101. The main body 100 provides a construction of a drainage port in the drainage system and bears the environmental pressure at the drainage port. The main body 100 is internally provided with a through working channel, which allows water flow to pass through and realize the drainage function.

[0030] As shown in the drawings, Figure 2 The top of the main body 100 is provided with a working opening. The working opening is the entrance of water flow into the main body 100 and the operation port during maintenance and inspection. The inner wall of the main body 100 is provided with a mounting step 101. The mounting step 101 provides a stable mounting base in the main body 100 and is used to fix and support the filter 300, so as to ensure that the filter 300 can be stably mounted in the main body 100.

[0031] As shown in the drawings, Figure 1 , Figure 2 The cover 200 is connected with the main body 100 and is detachably arranged on the working opening. The cover 200 is connected with the main body 100 and is detachably arranged on the working opening. When maintenance or inspection is needed, the cover 200 can be easily removed.

[0032] As shown in the drawings, Figure 1 , Figure 2 The cover 200 is provided with a plurality of through working holes 201. The working holes 201 allow water flow to pass through and provide additional ventilation and observation channels, so that maintenance personnel can check the water flow and internal structure.

[0033] As shown in the drawings, Figure 2 , Figure 4 Among them Figure 4 is a structural schematic view of the filter 300 provided by the embodiment of the application. The filter 300 is detachably connected on the mounting step 101. The filter 300 is provided with a plurality of filter holes 301. The filter 300 is detachably connected on the mounting step 101 of the main body 100, so that when the filter 300 needs to be replaced or cleaned, the operation can be quickly and conveniently performed. The filter 300 is provided with a plurality of filter holes 301 to ensure that impurities such as leaves, branches and other objects that may block the drainage system can be effectively filtered out.

[0034] As shown in the drawings, Figure 2 , Figure 3 Among them Figure 3A structural schematic diagram of the inverted state of the filter element 300 is provided for the embodiment of the present application. It should be noted that the filter element 300 can be assembled in different directions according to the operating conditions. When the filter element 300 is installed in a first direction, the filter element 300 is arranged as a whole in the operating channel, so that the filter element 300 is inside the operating channel and forms a filtering space in combination with the inner wall of the main body 100, so that the filtered debris is gathered in the filtering space, which is convenient for regular cleaning. The filter element 300 can also be installed in a second direction. In this state, a part of the filter element 300 extends above the operating opening and extends to the upper part of the water surface during drainage, forming a warning effect for the wellhead at that location, thereby preventing relevant operators or equipment from falling.

[0035] In an optional embodiment, the working principle of the wellhead device in the present application is: the wellhead device includes a main body 100, a cover 200 and a filter 300, the main body 100 is provided with a through working channel, the top of the main body 100 is provided with an operating opening, the inner wall of the main body 100 is provided with a mounting step 101, the cover 200 is connected to the main body 100 and is detachably arranged on the operating opening, the cover 200 is provided with a plurality of through working holes 201, the filter 300 is detachably connected to the mounting step 101, the filter 300 is provided with a plurality of filter holes 301, and when the wellhead device is assembled into the drainage system for operation, the operation hole 201 on the cover 200 and the main body are connected. The working channel in the body 100 performs stable drainage operations. During normal drainage, the cover 200 is assembled on the installation step 101, and the filter hole 301 is used to block and filter debris while draining, so as to prevent debris from accumulating in the drainage system and forming a blockage. During the drainage operation, after the cover 200 is lost, the filter 300 can still form a blockage in the working channel to avoid the danger of falling. In special drainage conditions, the cover 200 can be removed and the filter 300 can be reversely installed on the installation step 101. On the one hand, it can further prevent the accumulation of debris from affecting the drainage efficiency. On the other hand, the reversely installed cover 200 can also form a warning effect above the drainage surface on the working opening, thereby further improving the safety of the drainage operation there.

[0036] like Figure 2 、 Figure 4 As shown, in an optional embodiment, the filter element 300 is funnel-shaped, and a connecting ring 302 is provided on the filter element 300 . The connecting ring 302 can be stacked on the installation step 101 .

[0037] The funnel-shaped filter 300 enhances the structural stability and optimizes the efficiency of water flow. The funnel-shaped filter 300 can receive a large amount of water flow through the wide top, while the narrow bottom helps to concentrate the water flow, making the water flow more evenly through the filter holes 301 when passing through the filter 300, thereby improving the filtering effect.

[0038] In addition, the filter 300 is provided with a connecting ring 302, which allows the filter 300 to be conveniently stacked on the mounting step 101. This mounting method is not only simple and fast, but also ensures that the filter 300 is stably placed in the main body 100, avoiding displacement due to water flow impact or other external forces. The specifications of the connecting ring 302 match those of the mounting step 101, ensuring the sealing between the filter 300 and the main body 100, preventing unfiltered water from bypassing the filter 300 and directly flowing into the working channel. This close fit also helps to reduce the possibility of leakage during installation and maintenance, improving the reliability and durability of the entire wellhead device.

[0039] As shown in Figure 2 , Figure 4 In an optional embodiment, the mounting step 101 is provided with a plurality of positioning portions 401, and the connecting ring 302 is provided with a plurality of positioning holes 402 corresponding to the positioning portions 401, and when the filter 300 is connected to the mounting step 101, the positioning portions 401 extend into the positioning holes 402.

[0040] To ensure the precise fit and stable connection between the filter 300 and the main body 100, the mounting step 101 is provided with a plurality of positioning portions 401, which are part of the mounting step 101. The shape, position, and specifications of the positioning portions 401 match those of the connecting ring 302 on the filter 300, improving the convenience of installing the filter 300 and enhancing the structural stability and reliability of the entire wellhead device. The connecting ring 302 is part of the filter 300, located at the edge of the filter 300, and a plurality of positioning holes 402 are provided on the connecting ring 302, which correspond one-to-one with the positioning portions 401 on the mounting step 101, ensuring that the filter 300 can be accurately placed at the predetermined position of the main body 100.

[0041] When the filter 300 is connected to the mounting step 101, the positioning part 401 will extend into the corresponding positioning hole 402, forming a firm connection. The cooperation of the positioning part 401 and the positioning hole 402 allows the filter 300 to have a clear positioning point on the mounting step 101, thereby avoiding displacement or rotation of the filter 300 under the impact of water flow or external pressure. It also helps to ensure the alignment of the filter hole 301 with the working channel, optimizing the efficiency of water flow through the filter 300. In addition, the cooperation of the positioning part 401 and the positioning hole 402 also simplifies the replacement and maintenance process of the filter 300. When it is necessary to replace the filter 300 or perform cleaning, it is only necessary to simply remove the filter 300 from the mounting step 101 without the need for complex adjustment or repositioning. This ability to quickly disassemble and install makes maintenance more efficient and also reduces the risk of potential failure due to improper maintenance.

[0042] As shown in Figure 2 , Figure 3 In an optional embodiment, the height of the filter 300 in the direction of the longitudinal center line of the main body 100 is greater than the distance between the mounting step 101 and the working opening.

[0043] The distance between the mounting step 101 and the working opening allows the upper part of the filter 300 to form a space for filtering debris when the filter 300 is installed in the working channel of the main body 100, improving stability, and the height of the filter 300 is greater than the distance between the mounting step 101 and the working opening. When the filter 300 is installed in reverse, one end of the filter 300 can stably extend out of the water surface to form a wellhead warning effect. When the wellhead position cannot be observed due to sewage and other working conditions, the warning reminder function can also be achieved through different installation methods of the filter 300.

[0044] As shown in Figure 1 , Figure 2 In an optional embodiment, the main body 100 is provided with a first positioning ring 501, and the cover 200 is provided with a second positioning ring 502 that can cooperate with the first positioning ring 501. When the cover 200 is arranged on the main body 100, the first positioning ring 501 can be coaxially sleeved on the second positioning ring 502.

[0045] Specifically, the main body 100 is provided with a first positioning ring 501, which enhances the structural stability of the main body 100 and also provides a clear reference point for guiding the correct installation of the cover 200. The first positioning ring 501 is a protruding part of the edge of the main body 100, which extends circumferentially around the working opening of the main body 100 to form a ring structure. The diameter and shape of the first positioning ring 501 match those of the second positioning ring 502 on the cover 200.

[0046] The first positioning ring 501 allows the cover 200 to be quickly and accurately positioned on the main body 100 during installation, ensuring the coaxiality between the cover 200 and the main body 100, which is crucial for maintaining uniform water distribution and preventing debris from entering the working channel. The cover 200 is provided with a second positioning ring 502 that can cooperate with the first positioning ring 501. The second positioning ring 502 is a groove or protrusion on the edge of the cover 200, which corresponds in size and shape to the first positioning ring 501. When the cover 200 is arranged on the main body 100, the second positioning ring 502 can be coaxially sleeved on the first positioning ring 501, ensuring accurate alignment between the cover 200 and the main body 100, while also providing additional stability to prevent the cover 200 from rotating or shifting during use. In the wellhead device, the cooperation of the first positioning ring 501 and the second positioning ring 502 can also ensure the stable installation of the cover 200 on the main body 100, and even in the case of water flow impact or external environmental changes, the relative position can remain unchanged, ensuring the long-term effective operation of the drainage system.

[0047] As shown in Figure 1 , Figure 2 In an optional embodiment, the first positioning ring 501 is provided with a plurality of first positioning grooves 503, and the cover 200 is provided with a plurality of first positioning blocks 504 that can extend into the first positioning grooves 503.

[0048] The first positioning ring 501 is provided with a plurality of first positioning grooves 503, which can be uniformly distributed circumferentially. The cover 200 is also provided with a plurality of first positioning blocks 504 that can extend into the first positioning grooves 503. The first positioning blocks 504 cooperate with the first positioning grooves 503 during installation to achieve precise positioning and fixation.

[0049] When the cover 200 is arranged on the main body 100, the first positioning block 504 extends into the first positioning groove 503, forming an accurate connection, not only improving the installation efficiency, but also enhancing the stability and reliability during use. The use of the first positioning block 504 and the first positioning groove 503 can effectively fix the cover 200 and prevent it from loosening, better serving various drainage needs, ensuring the smoothness of the drainage system, simplifying the replacement and maintenance process of the cover 200, making the maintenance work more efficient, and also reducing the potential failure risk caused by improper maintenance.

[0050] As shown in Figure 1 , Figure 2 In an optional embodiment, a compression ring part 601 is fixed on the top edge of the main body 100. The compression ring part 601 fixedly connected on the main body 100 can be fixedly connected by welding or the like, and when the main body 100 is arranged, the connection reliability when arranged in the installation position is improved, facilitating construction arrangement and improving the reliability of the main body 100 in the drainage system.

[0051] As shown in Figure 1 , Figure 2 In an optional embodiment, a connecting part 602 is fixed on the bottom edge of the main body 100. The connecting part 602 fixedly connected on the main body 100 can be fixedly connected by welding or the like, and when the main body 100 is arranged, the convenience of connecting with the lower pipe network of the installation position is improved, facilitating construction arrangement and improving the reliability of the main body 100 in the drainage system.

[0052] As shown in Figure 4 In an optional embodiment, a plurality of operation rings 303 are arranged on the filter 300, facilitating holding or clamping the operation ring 303 and performing assembly, maintenance and other operations of the filter 300.
