[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] like Figures 1 to 4 As shown, the wellhead square pit drainage device includes a self-priming pump M, a controller N and a remote controller P. The remote controller P controls the controller N, and the controller N controls the self-priming pump M.

[0023] The controller N comprises a box body N1, on which an input jack N2, an extension jack N3, an infrared sensing window N4 and a controller power line N5 are arranged.

[0024] The input socket N2 is detachably connected to the pump body power line 10 .

[0025] The extension socket N3 is connected to a liquid level sensor T through an extension plug Q and an extension connection line R. The liquid level sensor T is arranged in the square pit at the wellhead.

[0026] In addition, a pair of suspension heads N11 are provided on the box body N1. The remote controller P is an infrared remote controller.

[0027] like Figure 5 As shown, the self-priming pump M comprises a pump body 5, a motor 9 and a pump body power cord 10, an impeller 1 is arranged inside the pump body 5, a pivot 91 of the motor 9 drives the impeller 1, a mechanical seal 4 and a water retaining ring 3 are arranged on the pivot 91, the mechanical seal 4 is close to the impeller 1, a pump cover 2 is arranged on the upper part of the pump body 5, a bleed valve 7 is arranged on the pump cover 2, a suction channel S is arranged at the bottom of the pump body 5, a drain plug 8 is arranged at the bottom of the suction channel S, and a pressure taking plug 6 is arranged at the top of the suction channel S.

[0028] It should be noted that the self-priming pump M utilizes the gas-liquid mixing principle to realize gas suction, and can form a certain degree of vacuum state in the suction channel S. It only needs to draw water when used for the first time, and thereafter, there is no need to repeat the water drawing step each time it is used, which greatly improves convenience.

[0029] The working mode of the wellhead square pit drainage device is described below.

[0030] Plug the plug of the pump body power cord 10 of the self-priming pump M directly into the input jack N2 of the controller N, and then connect the controller power cord N5 to the power supply. Finally, insert the extension plug Q into the extension jack N3, and fix the liquid level sensor T to the warning height of the wellhead square pit.

[0031] When the liquid level in the wellhead square pit exceeds the warning height, the liquid level sensor T is triggered, and then the input jack N2 is powered on, the self-priming pump M is started, and the liquid in the wellhead square pit is automatically drained, which is safe and reliable and avoids accidents. In addition, using the remote control P, the user can manually perform forced drainage operations at any time, which can be remotely controlled and is more user-friendly.

[0032] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
