DETAILED DESCRIPTION

[0014] The utility model is further described in detail below through specific implementation methods:

[0015] like Figure 1 As shown, an embodiment of the utility model proposes a tunnel maintenance emergency drainage device, including a support frame 1, a mounting seat 2, a collecting bucket 3 and a connecting head 4; wherein, the mounting seat 2 is detachably connected to the top of the support frame 1, and a connecting hole is opened on the mounting seat 2; the bottom of the collecting bucket 3 is connected to a connecting pipe 5 connected to the inside thereof, and the connecting pipe 5 is adapted to the connecting hole so that the bottom of the collecting bucket 3 is abutted against the mounting seat 2; one end of the connecting head 4 is threadedly connected to the connecting pipe 5 and a limiting portion 6 is formed on its outer wall abutting against the bottom of the mounting seat 2, and the other end of the connecting head 4 is connected to a drainage hose (the drainage hose is not shown in the accompanying drawings).

[0016] When used in this embodiment:

[0017] First, insert the connecting pipe 5 into the connecting hole, and then insert one end of the connecting head 4 into the connecting pipe 5 to connect them by threading until the limiting part 6 abuts against the bottom of the mounting seat 2. At this time, the connecting head 4, the mounting seat 2 and the collecting bucket 3 are connected into a whole; then the supporting frame 1 is threadedly connected to the mounting seat 2, and one end of the drainage hose is tightened and sleeved on the end of the connecting head 4 away from the connecting pipe 5 to complete the installation for use.

[0018] After use, if you need to disassemble it for storage:

[0019] First, disconnect the support frame 1 from the mounting base 2, and disconnect the drain hose from the connector 4; then rotate the connector 4 to disconnect it from the connecting pipe 5, and then remove the connecting pipe 5 from the connecting hole to complete the disassembly.

[0020] like Figure 1As shown, according to another embodiment of the utility model, in the tunnel maintenance emergency drainage equipment, the limiting portion 6 is an annular limiting block formed on the outer wall of the connecting head 4 along its circumferential direction.

[0021] Among them, the annular limit block is integrally formed with the connecting head 4 and has sufficient connection strength; when connecting, the connecting head 4 is rotated to move the connecting head 4 into the connecting pipe 5 until the annular limit block abuts against the bottom of the mounting seat 2. At this time, the connecting head 4, the mounting seat 2 and the collecting bucket 3 are connected as a whole.

[0022] In order to reduce the resistance of the rainwater collected in the collecting hopper 3 to enter the drainage hose, Figure 1 As shown, according to another embodiment of the utility model, in the tunnel maintenance emergency drainage device, the inner wall of one end of the connector 4 placed in the connecting pipe 5 is funnel-shaped. This is conducive to quickly introducing the rainwater collected in the collecting hopper 3 into the drainage hose, thereby reducing the resistance of rainwater entering the connector 4.

[0023] In order to prevent the rainwater from splashing out of the collecting bucket 3 during the rainwater collection process; Figure 1 As shown, according to another embodiment of the utility model, a tunnel maintenance emergency drainage device is described, wherein a plurality of splash-proof protrusions 7 are evenly distributed on the inner bottom wall of the collecting bucket 3; after the rainwater is collected in the collecting bucket 3, it contacts the splash-proof protrusions 7, thereby reducing the degree of splashing of the rainwater and changing the direction of splashing of the rainwater, thereby preventing the rainwater from splashing outside the collecting bucket 3.

[0024] Specifically in this embodiment:

[0025] Each of the splash-proof protrusions 7 is hemispherical, making the inner bottom wall of the collecting bucket 3 uneven, on the one hand to reduce the degree of splashing of rainwater, on the other hand to ensure that there are no dead corners in the collecting bucket 3, to ensure that the rainwater collected in the collecting bucket 3 can be discharged from the connecting pipe 5.

[0026] In order to improve the assembly stability between the mounting base 2 and the collecting bucket 3, as Figure 1 As shown, according to another embodiment of the utility model, a tunnel maintenance emergency drainage device is provided, wherein the mounting seat 2 is provided with a positioning groove, and the collecting bucket 3 is connected with a positioning column 8 adapted to be in the positioning groove.

[0027] Here, the positioning column 8 is adapted to the positioning groove, and cooperates with the connecting pipe 5 to be adapted to the connecting hole to connect with the connecting head 4, thereby improving the connection stability between the mounting seat 2 and the collecting bucket 3 after assembly. The cross section of the positioning column 8 can be circular, triangular, quadrilateral or pentagonal, etc. The cross section of the positioning column 8 is preferably triangular, quadrilateral or pentagonal, so that the positioning column 8 is more stable after being adapted to the positioning groove.

[0028] In order to facilitate the adjustment of the height of the tunnel maintenance emergency drainage equipment and facilitate storage, Figure 1 As shown, according to another embodiment of the utility model, a tunnel maintenance emergency drainage device, wherein the support frame 1 includes a base 11, a fixed cylinder 12, a sliding rod 13 and a locking member 14; wherein the fixed cylinder 12 is detachably connected to the base 11; one end of the sliding rod 13 is slidably connected in the fixed cylinder 12 and the other end thereof is detachably connected to the mounting seat 2; the locking member 14 is detachably connected between the fixed cylinder 12 and the sliding rod 13 and is used to lock or unlock the fixed cylinder 12 and the sliding rod 13.

[0029] In this embodiment:

[0030] When the height needs to be adjusted, the locking member 14 is unlocked to allow the fixed cylinder 12 and the sliding rod 13 to slide relative to each other. At this time, after the sliding rod 13 is moved to adjust to a suitable position, the locking member 14 is locked to lock and fix the adjusted fixed cylinder 12 and the sliding rod 13 to meet the height requirements.

[0031] The base 11 and the fixed cylinder 12 are connected by a threaded connection method, which is convenient for connecting or disassembling the base 11 and the fixed cylinder 12; the sliding rod 13 and the mounting seat 2 are also connected by a threaded connection method, which is convenient for connecting or disassembling the sliding rod 13 and the mounting seat 2. The locking member 14 can be a locking bolt, which has a simple structure. The locking bolt is threadedly connected to the fixed cylinder 12. When the locking bolt is rotated to make one end of it abut against the sliding rod 13, the fixed cylinder 12 and the sliding rod 13 are locked; when the locking bolt is rotated in the opposite direction to make one end of it disengage from the abutment with the sliding rod 13, the fixed cylinder 12 and the sliding rod 13 are unlocked, and the relative length between the fixed cylinder 12 and the sliding rod 13 can be adjusted.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
