DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear, explicit and understood, the following will be further described in detail by combining the accompanying drawings of the embodiment, and the embodiment. Figures 1-5 and the embodiment, the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] Referring to Figure 1 and Figure 2 , an outdoor sewage connection buffer pool comprises a pool body 1, a water inlet pipe 2, a water outlet pipe 3, a broken grid device 4 and a lifting spiral device 5, wherein the water inlet pipe 2 and the water outlet pipe 3 are both horizontally arranged and respectively connected with two sides of the pool body 1, and the horizontal position height of the water inlet pipe 2 is higher than that of the water outlet pipe 3. The horizontal position height difference of the water inlet pipe 2 and the water outlet pipe 3 is set as "L", and the horizontal position height difference of the water inlet pipe 2 and the water outlet pipe 3 satisfies L>80mm. The horizontal position height of the water outlet pipe 3 is set to be lower than that of the water inlet pipe 2, so that the sundries in the pool body 1 can be directly discharged from the water outlet pipe 3 when the sundries in the pool body 1 are accumulated to a certain height.

[0027] Referring to Figure 3 and Figure 4The broken grid device 4 and the lifting screw device 5 are arranged in the pool body 1, the broken grid device 4 comprises a grid 41, a first power assembly 42, a first transmission shaft 43 and a plurality of broken pages 44, the grid 41 is arranged at the pipe orifice of the water inlet pipe 2, so as to block the pipe orifice of the water inlet pipe 2, so as to block the large particle impurities in the water inlet pipe 2. The first power assembly 42 is arranged as a speed reducer, and the first power assembly 42 is fixed in the pool body 1, the rotating shaft of the speed reducer is arranged horizontally and parallel to the grid 41, the first transmission shaft 43 is coaxially arranged with the rotating shaft of the speed reducer and is fixed with the rotating shaft of the speed reducer.

[0028] The plurality of broken pages 44 are fixed with the first transmission shaft 43, so that the two sides of the plurality of broken pages 44 are flush, the plurality of broken pages 44 are arranged in the grid 41 and located between the adjacent two grid bars of the grid 41. The pipeline blockage detection device 6 is arranged in the water inlet pipe 2 close to the grid 41, and the pipeline blockage detection device 6 is electrically connected with the first power assembly 42. When the pipeline blockage detection device 6 detects that the water inlet pipe 2 is blocked, the rotating shaft of the first power assembly 42 rotates to drive the first transmission shaft 43 to rotate, the first transmission shaft 43 rotates to drive each broken page 44 to rotate, so as to crush the large particle impurities close to the grid 41 in the water inlet pipe 2. The crushed large particle impurities can pass through the grid 41 into the pool body 1, preventing the large particle impurities from directly entering the pool body 1, and preventing the large particle impurities from blocking the water inlet pipe 2.

[0029] Referring to Figure 2 , Figure 3 and Figure 5 , the lifting screw device 5 comprises a second power assembly 51, a second transmission shaft 52, a lifting pipe 53 and a spiral blade 54, the second power assembly 51 is also arranged as a speed reducer, and the second power assembly 51 is fixed on the side wall of the pool body 1, the second transmission shaft 52 is fixed on the rotating shaft of the speed reducer, and the spiral blade 54 is arranged on the periphery of the second transmission shaft 52. One end of the drain pipe extends into the pool body 1, and the end of the drain pipe in the pool body 1 is bent upward, the top end of the lifting pipe 53 is arranged to form a lap joint portion 531, the lifting pipe 53 is arranged obliquely, so that the lap joint portion 531 at the top end of the lifting pipe 53 abuts against the drain pipe, and the second transmission shaft 52 and the spiral blade 54 are arranged in the lifting pipe 53. The inclination angle between the lifting pipe 53 and the ground is "A", and the inclination angle between the lifting pipe 53 and the ground satisfies 30 degrees < A < 60 degrees. Thus, the inclination angle between the lifting pipe 53 and the ground is kept appropriate, when the impurities in the pool body 1 accumulate to a certain height, the rotating shaft of the speed reducer rotates to drive the second transmission shaft to rotate, and the impurities in the pool body 1 are lifted by the spiral blade 54 to enter the water inlet pipe 3, so that the impurities can be smoothly discharged from the drain pipe.

[0030] In order to avoid the accumulation of sundries in the corners of the pool body 1, a concrete block 11 is arranged at the corner of the pool body 1, the arranged concrete block 11 is located obliquely below the lifting pipe 53, and the surface of the concrete block 11 is arc-shaped. In this way, the sundries above the concrete block 11 can slide along the surface of the concrete block 11 to the bottom end of the lifting pipe 53, so that the sundries can be easily extracted by the lifting screw device 5. An inspection manhole 12 is formed at the top end of the pool body 1, when the broken grate device 4 and the lifting screw device 5 in the pool body 1 fail, the staff can maintain the broken grate device 4 and the lifting screw device 5 from the inspection manhole 12, and the opening of the inspection manhole 12 facilitates the maintenance of the staff.

[0031] The broken grate device 4 and the lifting screw device 5 are made of stainless steel, the broken grate device 4 and the lifting screw device 5 made of stainless steel have excellent corrosion resistance, so that a thin and strong oxide film can be formed on the surface, which can withstand high-speed water erosion in the pool body 1, thereby having a longer service life. And the broken grate device 4 and the lifting screw device 5 made of stainless steel have higher strength and are not easy to deform. The first power assembly 42 and the second power assembly 51 are both selected to be a reduction motor, the reduction motor has the characteristics of small speed and large torque, which is more in line with the working characteristics of the broken grate device 4 and the lifting screw device 5, so as to crush large particle sundries and extract sundries.

[0032] The specific implementation principle of the embodiment of the application is that during the process of discharging sewage from the water inlet pipe 2 into the pool body 1, the grate 41 blocks the large particle sundries in the water inlet pipe 2, so that the large particle sundries are accumulated at the grate 41. The rotating shaft of the reduction motor rotates to drive the first transmission shaft 43 to rotate, the first transmission shaft 43 rotates to drive each broken page 44 to rotate, and each broken page 44 breaks the large particle sundries on one side of the grate 41 in the rotating process. The large particle sundries can enter the pool body 1 together with the sewage through the grate 41, and as the water level of the sewage in the pool body 1 rises, due to the fact that the horizontal position of the water outlet pipe 3 connected with the pool body 1 is lower than the horizontal position of the water inlet pipe 2, the sewage in the pool body 1 can be automatically discharged through the drain pipe.

[0033] When the water level of the sewage in the pool body 1 does not reach the position of the drain pipe, the rotating shaft of the speed reducer rotates to drive the second transmission shaft 52 to rotate, thereby driving the spiral blade 54 fixed on the second transmission shaft 52 to rotate. In the process of rotation, the spiral blade 54 lifts the sludge at the bottom end of the pool body 1 together with the sewage, and the sludge and the sewage are spirally lifted under the action of the spiral blade 54, so that the sludge and the sewage are transmitted into the water outlet pipe 3. The sundries and the sewage located at the corner of the bottom end of the pool body 1 also slide along the curved surface of the concrete block 11 to the end of the bottom end of the lifting pipe 53, thereby avoiding the accumulation of the sundries at the corner of the bottom end of the pool body 1.

[0034] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, all of them are within the protection scope of the utility model.
