[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 This utility model provides a prefabricated sewage treatment device, including an upper frame 4 and a lower frame 3. The upper frame 4 is detachably connected to the lower frame 3 through an assembly mechanism 1.
[0029] The assembly mechanism 1 includes a first assembly plate 101 and a second assembly plate 103. The first assembly plate 101 and the second assembly plate 103 are disposed on both sides of the bottom of the upper frame 4. The first assembly plate 101 corresponds to the first assembly groove 104, and the second assembly plate 103 corresponds to the second assembly groove 105. The first assembly groove 104 and the second assembly groove 105 are symmetrically disposed on both sides of the lower frame 3. The first assembly plate 101 is connected to the longitudinal adjustment mechanism 2 through a snap-fit assembly.
[0030] The snap-fit assembly includes a positioning pin 110, which is movably disposed in a storage groove 109. The storage groove 109 is disposed on one side of the first assembly plate 101. A return spring 107 is also disposed in the storage groove 109. One end of the return spring 107 is fixedly connected to the positioning pin 110, which can automatically connect the first assembly plate 101 to the ball screw pair 203.
[0031] In practical application, firstly, the bottom of the filter screen 5 is inserted into the lower positioning frame 6. Then, the upper frame 4 and the lower frame 3 are assembled. The first assembly plate 101 and the second assembly plate 103 on the upper frame 4 are aligned with the first assembly groove 104 and the second assembly groove 105. The first assembly plate 101 and the second assembly plate 103 are inserted into the first assembly groove 104 and the second assembly groove 105. When the positioning pin 110 is in contact with the ball screw pair 203, the positioning pin 110 moves in the receiving groove 109 and compresses the first spring. When the positioning pin 110 moves to the position of the positioning groove 205, the return spring 107, under the action of elasticity, inserts the positioning pin 110 into the positioning groove 205, thereby connecting the first assembly plate 101 and the ball screw pair 203. At the same time, the upper frame 4 and the lower frame 3 are assembled. At this time, the upper positioning frame 7 in the upper frame 4 is engaged and fixed to the upper end of the filter screen 5.
[0032] In one embodiment, one end of the positioning pin 110 is engaged in the positioning groove 205, which is located on one side of the ball screw pair 203, and can accurately position the engagement position of the positioning pin 110.
[0033] In one embodiment, limiting blocks 102 are provided on both sides of the first assembly plate 101 and the second assembly plate 103. The limiting blocks 102 correspond to the limiting slots 106. The limiting slots 106 are symmetrically arranged on both sides of the first assembly slot 104 and the second assembly slot 105. When the first assembly plate 101 and the second assembly plate 103 are inserted into the first assembly slot 104 and the second assembly slot 105, the limiting blocks 102 are inserted into the limiting slots 106, which can position the installation of the first assembly plate 101 and the second assembly plate 103.
[0034] In one embodiment, a locking knob 108 is also provided on one side of the first assembly plate 101. One end of the locking knob 108 abuts against the positioning pin 110. When the positioning pin 110 is inserted into the positioning slot 205, the locking knob 108 is turned, and the end of the locking knob 108 fits against the bottom of the positioning pin 110, which can assist in positioning the positioning pin 110 and improve the firmness of the positioning pin 110 when it is engaged.
[0035] Please see Figure 5 , Figure 7 as well as Figure 8A longitudinal adjustment mechanism 2 is also provided in the first assembly slot 104. The longitudinal adjustment mechanism 2 includes an installation slot 201, which is located on one side of the first assembly slot 104. A longitudinal lead screw 202 is rotatably installed in the installation slot 201. A ball screw pair 203 is installed on the longitudinal lead screw 202. The rotation of the longitudinal lead screw 202 can drive the ball screw pair 203 to move longitudinally. A driven bevel gear 207 is provided on one side of the longitudinal lead screw 202. The driven bevel gear 207 meshes with the driving bevel gear 206. The driving bevel gear 206 is located at one end of the adjustment knob 204. The adjustment knob 204 is rotatably located on one side of the first assembly plate 101. The rotation direction of the longitudinal lead screw 202 can be controlled by the transmission between the driving bevel gear 206 and the driven bevel gear 207.
[0036] When it is necessary to disassemble the filter screen 5, the adjustment knob 204 can be rotated. The adjustment knob 204 drives the driving bevel gear 206 to rotate, the driving bevel gear 206 drives the driven bevel gear 207 to rotate, the driven bevel gear 207 drives the longitudinal lead screw 202 to rotate, and the ball screw pair 203 drives the first assembly plate 101 to move in the first assembly groove 104. The first assembly plate 101 drives the upper frame 4 to rise, and at the same time the second assembly plate 103 moves in the second assembly groove 105. When the upper positioning frame 7 in the upper frame 4 separates from the upper end of the filter screen 5, the filter screen 5 can be disassembled.
[0037] In one embodiment, a lower positioning frame 6 is provided at the bottom of the lower frame 3, and an upper positioning frame 7 corresponding to the lower positioning frame 6 is provided at the top of the upper frame 4, so as to facilitate the positioning and installation of the upper and lower ends of the filter screen 5.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
