Description

Technical Field

[0001] The utility model relates to the technical field of overflow well seats, in particular to an overflow well seat end clamping structure. Background Art

[0002] The overflow well seat is a device used to control the overflow of underground wells. It is usually installed at the top of the wellhead to control and adjust the overflow level of the wellhead. When the liquid level at the wellhead is too high, the overflow well seat can be opened to allow excess liquid to flow out to keep the liquid level in the wellhead within a safe range. Conversely, when the liquid level drops, the overflow well seat can be closed to prevent air or external impurities from entering the wellhead.

[0003] At present, the existing overflow well seat only has the ability to flip open and close. During long-term use, the well seat end and the manhole cover are prone to looseness, making it difficult to maintain the stability of the well seat end. Under the influence of external pressure, it is easy to loosen or open, causing the overflow port to lose control, affecting the normal operation and use of the overflow well seat. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a clamping structure at the end of an overflow well seat, including a well seat, a limiting groove is provided on the top surface of the well seat, the inner wall of the limiting groove is movably connected with a well cover, the inner wall of the limiting groove is provided with a telescopic groove, the inner wall of the telescopic groove is movably connected with a clamping plate, the lower outer wall of the well cover is provided with a clamping groove, one end of the clamping plate is movably clamped in the inner wall of the clamping groove, and a spring is fixedly connected between the other end of the clamping plate and the inner wall of the limiting groove, a movable groove is provided on the top surface of the well seat, the interior of the movable groove is connected with the interior of the telescopic groove, the inner wall of the movable groove is movably connected with a connecting plate, and the bottom end of the connecting plate is fixedly connected to the top surface of the clamping plate.

[0006] Preferably, a mounting hole is formed through the top surface of the well seat, and a connecting pipe is fixedly connected to the bottom surface of the well seat.

[0007] Preferably, a reinforcing rib is fixedly connected between the bottom surface of the well seat and the outer wall of the connecting pipe.

[0008] Preferably, a rotation groove is provided on the top surface of the well seat, and a rotation block is rotatably connected to the inner wall of the rotation groove, and one end of the rotation block is fixedly connected to the outer wall of the well cover.

[0009] Preferably, a fixing plate is fixedly connected to an outer wall on one side of the connecting plate.

[0010] Preferably, a bolt is threadedly connected through the top surface of the fixing plate.

[0011] Preferably, a limiting hole is provided below the bolt, and the limiting hole is opened on the top surface of the well seat.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, by pressing the manhole cover and closing the inside of the limit groove, the clamping plate automatically shrinks into the telescopic groove as the manhole cover is pressed. After the manhole cover is closed in place, the clamping plate automatically resets and engages with the inside of the clamping groove of the manhole cover under the elastic force of the spring, so that the manhole cover is firmly installed on the top of the well seat to avoid loosening during long-term use, thereby improving the stability of the utility model and helping to ensure the normal operation and use of the overflow well seat.

[0014] 2. In the utility model, by using the fixing plate, bolts and limiting holes in coordination, the user can turn the bolts to insert their bottom ends into the limiting holes, thereby limiting the movement of the connecting plate, thereby limiting the activity of the clamping plate, avoiding accidental opening of the manhole cover, and further ensuring the stable connection of the manhole cover on the manhole seat.
