The downdraft pipe well sleeve can effectively help the drainage and precipitation work in underground projects, play a major role in the stability of the downdraft pipe, and ensure the normal progress and safe operation of the project. The existing downdraft pipe well sleeve is placed outside the downdraft pipe, aligned and welded to complete the connection, but after the construction is completed, the connected downdraft pipe is usually difficult to disassemble and cannot be recycled. Utility Model Content

[0003] The purpose of the utility model is to provide a sewer well sleeve in order to solve the above-mentioned problem. Through the cooperation between the fixing mechanism and the clamping mechanism in the upper and lower cylinder bodies, the upper and lower cylinder bodies can be detachably installed, and can be disassembled after the construction is completed for subsequent reuse.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] The downwell casing comprises: a lower barrel and an upper barrel part, wherein a plurality of lower fixing holes are provided through the outer surface of the lower barrel, and the bottom side of the lower barrel and the top side of the upper barrel part are detachably arranged;

[0006] Three clamping mechanisms are arranged on the lower inner side of the upper half of the upper cylinder, and the clamping mechanism includes a second connecting cylinder, a clamping sleeve is fixedly arranged on one side of the second connecting cylinder, a slide plate is slidably arranged on the inner side of the clamping sleeve, and an arc plate is fixedly arranged on the bottom side of the slide plate.

[0007] Furthermore, two push rods are fixedly provided on the top side of the slide plate, two second fixing plates are detachably provided on the top side of the ferrule, a second groove is opened on one side of the second fixing plate, and a second spring sheet is fixedly provided on the top side of the second fixing plate.

[0008] Furthermore, three fixing mechanisms are arranged on the inner side of the lower cylinder body, and the fixing mechanism includes a first connecting cylinder, and a blocking guard plate is fixedly arranged on one side of the first connecting cylinder.

[0009] Furthermore, two first fixing plates are fixedly arranged on one side of the blocking guard plate, first grooves are opened on opposite sides of the two first fixing plates, and first elastic sheets are fixedly arranged on the bottom sides of the first fixing plates.

[0010] Furthermore, a slide groove is provided through the lower part of the upper surface of the upper cylinder body, and an auxiliary disassembly mechanism is rotatably arranged inside the slide groove. The auxiliary disassembly mechanism includes a rotating ring, and three connecting semicircles are fixedly arranged inside the rotating ring.

[0011] Furthermore, an inclined block is fixedly provided on the side of the connecting semi-dome, and a plurality of shifting rods are fixedly provided on the outer side of the rotating ring.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 As shown, the utility model provides a downwelling pipe well sleeve, comprising: a lower barrel 1 and an upper barrel upper part 2, wherein a plurality of lower fixing holes 3 are formed through the outer surface of the lower barrel 1, and the bottom side of the lower barrel 1 and the top side of the upper barrel upper part 2 are detachably arranged;

[0027] Three clamping mechanisms 8 are arranged at the lower inner side of the upper half part 2 of the upper cylinder body, and the clamping mechanism 8 includes a second connecting cylinder 801, and a clamping sleeve 802 is fixedly arranged on one side of the second connecting cylinder 801. The inner side of the clamping sleeve 802 is hollow, providing a sliding space for the slide plate 803. A slide plate 803 is slidingly arranged on the inner side of the clamping sleeve 802, and the top side of the slide plate 803 is connected to the push rod 807. An arc plate 804 is fixedly arranged on the bottom side of the slide plate 803, one side of which is a straight plate, and the side close to the inclined block 903 in the auxiliary disassembly mechanism 9 is in an arc shape, so that the inclined block 903 can lift the slide plate 803 through the arc plate 804.

[0028] Furthermore, two push rods 807 are fixedly provided on the top side of the slide plate 803. The push rods 807 push upward from the bottom side to push the second spring piece 808 upward from the bending point, which makes it easier to change the bending direction of the second spring piece 808. Two second fixing plates 805 are detachably provided on the top side of the sleeve 802. The second fixing plates 805 are fixed and limited by the push rods 807 running through the inside. A second groove 806 is provided on one side of the second fixing plate 805 to facilitate the movement of the push rod 807, and a second spring piece 808 is fixedly provided on the top side of the second fixing plate 805.

[0029] Furthermore, three fixing mechanisms 7 are arranged on the inner side of the lower barrel 1, and the fixing mechanism 7 includes a first connecting cylinder 701, and a blocking guard plate 702 is fixedly arranged on one side of the first connecting cylinder 701 to limit a fixing plate and guide the connection between the clamping mechanism 8 and the fixing mechanism 7.

[0030] Furthermore, two first fixing plates 703 are fixedly provided on one side of the blocking guard plate 702, and a first groove 705 is opened on the opposite side of the two first fixing plates 703, and a first elastic piece 704 is fixedly provided on the bottom side of the first fixing plate 703. The first groove 705 in the first fixing plate 703 makes the second elastic piece 808 and the second fixing plate 805 smoother when the clamping mechanism 8 moves upward and clamps with the fixing mechanism 7. At the same time, the first fixing plate 703 will squeeze the second elastic piece 808 inward through the first elastic piece 704, so that the inclination angle of the second elastic piece 808 changes to pass through the gap between the two first fixing plates 703.

[0031] Furthermore, a slide groove 5 is provided through the lower surface of the upper half part 2 of the upper cylinder body, and an auxiliary disassembly mechanism 9 is rotatably arranged inside the slide groove 5. The auxiliary disassembly mechanism 9 includes a rotating ring 901, and three connecting semicircles 902 are fixedly arranged inside the rotating ring 901. The auxiliary disassembly mechanism 9 rotates inside the slide groove 5 through the lever 904, and then contacts the clamping mechanism 8, removes the clamping mechanism 8 from the fixing mechanism 7, separates the sleeve, and is disassembled after the construction is completed for subsequent reuse.

[0032] Furthermore, an inclined block 903 is fixedly provided on the top side of the connecting semicircle 902, and a plurality of levers 904 are fixedly provided on the outer side of the rotating ring 901. The semicircular body of the connecting semicircle 902 faces downward, and the plane faces upward. The plane supports the inclined block 903, and the upper part of the inclined block 903 is inclined, and the lower part is a plane, which is connected to the plane of the connecting semicircle 902.

[0033] Furthermore, three connecting columns 6 are fixedly arranged on the inner side of the slide groove 5, and the lower part 10 of the upper cylinder body is fixedly arranged on the bottom side of the connecting columns 6. A plurality of upper fixing holes 4 are penetrated through the outer surface of the lower part 10 of the upper cylinder body. The connecting columns 6 connect and fix the upper part 2 of the upper cylinder body and the lower part 10 of the upper cylinder body together. The upper fixing holes 4 can be subsequently penetrated and fixed with bolts on the inside to fix the position of the downcomer.

[0034] Furthermore, the push rod 807 is arranged in the second groove 806 and passes through it, and the bottom side of the push rod 807 is connected to the slide plate 803. The push rod 807 connected to the top side of the slide plate 803 enables the slide plate 803 to move up and down with the push rod 807 when sliding inside the sleeve 802, pushing the second spring piece 808 upward, pushing the inclination angle of the second spring piece 808 upward, and tilting it upward, so as to facilitate the removal of the clamping mechanism 8 from the inside of the fixing mechanism 7.

[0035] With the above structure, the lower fixing hole 3 is aligned with the upper fixing hole 4, and then the top side of the upper barrel body 2 and the lower barrel body 1 are spliced ​​together. During the splicing process, the second spring piece 808 in the clamping mechanism 8 of the upper barrel body 2 contacts the first spring piece 704 from bottom to top, and the first spring piece 704 guides the second spring piece 808 into between the two first fixing plates 703. The second spring piece 808 continues to move upward, and then passes through the bend of the first spring piece 704 and is clamped on the top side of the first fixing plate 703 for fixing. The three fixing mechanisms 7 and the clamping mechanism 8 cooperate with each other to complete the splicing of the lower barrel body 1 and the upper barrel body 2. When the two need to be separated, the lever 904 is swung to rotate the lever 904 through the rotating ring 901, with the connecting semicircle 902 and the inclined block 903. When the inclined block 903 contacts the arc of the arc plate 804, the slide plate 803 on the top side is pushed upward through the arc plate 804. The slide plate 803 slides upward in the sleeve 802 and pushes the push rod 807. At this time, the push rod 807 moves upward to change the inclination angle of the second spring piece 808. At this time, the upper barrel body half part 2 is pulled downward, so that the second spring piece 808 can pass through the first fixed plate 703, so that the lower barrel body 1 and the upper barrel body half part 2 fall off.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
