Description

Technical Field

[0001] This utility model belongs to the technical field of drainage equipment, specifically, it relates to a mobile drainage pumping station. Background Technology

[0002] Mobile pumping stations are devices that can be flexibly moved indoors and outdoors to quickly respond to drainage, flood discharge, and other operational needs. They typically use diesel engines to drive self-priming sewage pumps for high-flow-rate pumping and are widely used in municipal engineering, water conservancy, and emergency rescue. These pumping stations achieve rapid water extraction and discharge by directly connecting the sewage pumps to inlet and outlet pipes, exhibiting strong on-site adaptability and operational efficiency. In practical applications, to meet different operating conditions, multiple high-power sewage pumps are often configured on the same mobile vehicle to enhance overall drainage capacity.

[0003] However, when existing mobile pumping stations pump sewage containing a large amount of impurities, the lack of an effective filtration device at the pump inlet allows solid impurities in the water to easily enter the pump body, causing impeller blockage or jamming and affecting the normal operation of the pump. Furthermore, under conditions of multiple pumps operating in parallel or at high power, the vibration generated by the pump body is significant, and the existing chassis structure has limited ability to ensure operational stability. The support effect of the outriggers could be improved under complex ground conditions, potentially affecting the stability of the equipment operation.

[0004] Based on the above problems, this utility model proposes a mobile drainage pumping station to solve the problems existing in the prior art. Utility Model Content

[0039] The following is combined Figures 1 to 7 The structure of the mobile drainage pumping station of this utility model is described.

[0040] A mobile drainage pumping station includes a mobile frame 1, positioning legs 2 mounted on the frame 1, and a drainage pump 4. The frame 1 is a plate-type mobile frame, and symmetrically mounted wheels 3 are installed at the bottom of the frame 1 for moving the pumping station during use. The positioning legs 2 are rotatably mounted on the four corners of the frame 1 to position the frame 1 when the drainage pump 4 is in use, preventing the frame 1 from violently shaking and tipping over due to severe vibration during pump operation. The drainage pumps 4 are arranged in an array on the frame 1 and are detachably connected to the frame 1. A pre-filter 5 is also installed at the inlet end of the drainage pump 4 to filter the water entering the inlet end of the drainage pump 4 during use, preventing the pump blades from becoming clogged.

[0041] In use, first adjust the position of the drainage pump station using the frame 1. After adjusting to the designated position, extend the positioning legs 2 and use them to position the drainage pump station, ensuring its stability during use. After positioning, connect the inlet pipe to the inlet end of the filter 5 to filter the water coming into the inlet pipe. Then connect the outlet end of the drainage pump 4 to the drainage pipe and turn on the drainage pump 4 to begin drainage operation.

[0042] In one specific implementation, such as Figure 1 As shown, to facilitate the connection between this drainage pump station and the trailer, a retaining post 6 can be detachably installed at the front end of the frame 1. The retaining post 6 is used in conjunction with a retaining slot at the rear of the trailer. This allows the retaining post 6 to be inserted into the retaining slot and fixed to the frame 1 during use, thus connecting the drainage pump station to the trailer.

[0043] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning leg 2 is rotatably mounted on the frame 1 via a positioning post 21 located on the upper side of the frame 1, so that the frame 1 can be supported by adjusting the support position of the positioning leg 2 during use, thereby ensuring the stability of the frame 1 when the drainage pump 4 is working.

[0044] Specifically, the positioning outrigger 2 includes a support arm 22, a hydraulic component 23, and a support plate 24. One end of the support arm 22 is rotatably connected to the positioning post 21, and the other end is fixedly connected to the hydraulic component 23. The support plate 24 is disposed at the lower end of the piston rod of the hydraulic component 23 and is used to adjust the support position of the positioning outrigger 2 relative to the frame 1 by rotating the support arm 22 during use, so that it can match the support requirements of the frame 1 under different support stability and terrain requirements.

[0045] More specifically, in order to support the support arm 22, a support collar 211 is integrally formed on the outer side of the bottom of the positioning column 21, and a support platform is formed on the top of the support collar 211, which is used to support the support arm 22 during use.

[0046] Specifically, in order to lock the position of the support arm 22 after it rotates, the positioning leg 2 is designed to include a positioning collar 25. The positioning collar 25 is movably sleeved on the upper end of the positioning post 21 and is used in conjunction with the support arm 22 to lock the position of the support arm 22 during use.

[0047] More specifically, a plurality of positioning protrusions 251 are provided on the inner side of the positioning collar 25. The positioning protrusions 251 cooperate with the positioning grooves 212 provided on the outer side wall of the positioning post 21. During use, the positioning collar 25 is limited by the cooperation between the positioning protrusions 251 and the positioning grooves 212, so as to prevent the positioning collar 25 from rotating relative to the positioning post 21 after installation.

[0048] More specifically, a plurality of limiting blocks 252 are provided at the lower end of the positioning collar 25. The limiting blocks 252 cooperate with the limiting slots 221 provided on the end sleeve of the support arm 22. After the positioning collar 25 is installed on the positioning post 2, the position of the support arm 22 is limited by inserting the limiting blocks 252 into the limiting slots 221, so as to prevent the support arm 22 from rotating after the positioning adjustment is completed, and to ensure the stability of the frame 1.

[0049] Specifically, to prevent the positioning collar 25 from slipping after installation, the positioning leg 2 is designed to also include a positioning nut 26, which is threaded to the upper end of the positioning post 21 and is used to position the positioning collar 25 after installation.

[0050] In one specific implementation, such as Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the filter 5 includes a housing 51 and a filter element 55 installed inside the housing 51. The housing 51 is a rigid hollow shell, and its liquid inlet 56 is connected to the inlet pipe flange, while its drain outlet 57 is connected to the inlet flange of the drain pump 4. A slag discharge outlet 53 is also provided at the bottom of the housing 51, and a control valve 54 is provided on the slag discharge outlet 53 to control its opening and closing. The filter element 55 is detachably installed inside the housing 51, and a liquid guide port 58 is provided on the filter element 55 and connected to the drain outlet 57. In use, the filter element 55 filters the liquid impurities inside the housing 51, and the filtered impurities are discharged through the slag discharge outlet 53. The filtered liquid is discharged into the drain pump 4 through the liquid guide port 58 and the drain outlet 57 to avoid clogging the drain pump 4.

[0051] Specifically, a mounting plate 52 is provided on the top of the filter element 55. The mounting plate 52 is connected to the filter element 55 through a lower connecting ring 59. The connecting ring 59 also matches the upper opening on the outer casing 51, so that the mounting plate 52 can be easily fixed during use, and the matching filter element 55 can be replaced as needed.

[0052] The operating principle of the mobile drainage pumping station described in this utility model includes:

[0053] When in use, first use the moving wheels 3 of the frame 1 to adjust the position of this drainage pump station, and after adjusting it to the designated position;

[0054] Remove the positioning collar 25 and positioning nut 26, and rotate the support arm 22 to open the positioning leg 2. Adjust the opening angle to meet the support stability requirements of the frame 1. Then install the positioning collar 25 so that the positioning protrusion 251 is inserted into the positioning slot 212 and the limiting block 252 is engaged in the limiting slot 221 to limit the position of the support arm 22. Install the positioning nut 26 to lock the position of the support arm 22. Finally, control the hydraulic component 23 to make the support plate 24 act on the ground to position the frame 1.

[0055] Finally, connect the inlet pipe to the inlet end of the filter 5, filter the water coming into the inlet pipe using the filter 5, and connect the outlet end of the drain pump 4 to the drain pipe, then turn on the drain pump 4 to start working, thus realizing the operation of draining water using this drain pump station.

[0056] It should be noted that in this utility model, the above-mentioned drainage pump 4 and hydraulic component 23 are both prior art known to those skilled in the art. The power supply method of the drainage pump 4 and the hydraulic loading method of the hydraulic component 23 are both prior art. Operators can choose according to specific working conditions, and will not elaborate here.

[0057] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
