[0030] Embodiment 1
[0031] Referring to Figure 1 - Figure 2 , which is the first embodiment of the present utility model. This embodiment provides a drainage device, including a collection assembly 100, which includes a pipe 101, a collection box 102 used in conjunction with the pipe 101, the collection box 102 is used to receive seepage or leakage at the connection of the two pipes 101, fixing members 103 and a drain pipe 104 symmetrically arranged on the collection box 102. The collection box 102 is fixed on the pipe 101 through the fixing members 103, and the drain pipe 104 can be connected to a water diversion hose. Through the water diversion hose, water can enter the water diversion hose through the drain pipe 104, and then enter the drainage ditch through the water diversion hose. And a diversion member 105 arranged on the collection box 102, through which the seepage can be effectively dispersed, reducing the risk of single-point pressure and blockage;
[0032] A protection assembly 200, which includes placement grooves 201 symmetrically opened on the collection box 102, sliding grooves 202 symmetrically opened on the placement grooves 201, a support block 203 slidably installed on one of the sliding grooves 202, and an extension member 204 used in conjunction with the support block 203 to block both sides of the connection of the two pipes 101.
[0033] Specifically, the fixing member 103 includes straps 103a symmetrically arranged on the collection box 102, and an anti-slip pad 103b and a buckle 103c fixedly installed on the straps 103a.
[0034] Furthermore, the shape of the anti-slip pad 103b is arc-shaped. The side of the anti-slip pad 103b away from the strap 103a is in contact with the pipe 101. A number of rubber pads are fixedly connected to the surface of the anti-slip pad 103b in contact with the pipe 101 and are arranged at equal intervals to increase the friction of the anti-slip pad 103b through the number of rubber pads.
[0035] Operation process: When in use, separate the buckle 103c between the two straps 103a so that they are no longer engaged, then bring the straps 103a into contact with the outer wall of the pipe 101, and then engage the buckle 103c again. Then repeat the above steps for the other fixing member 103 to fix the collection box 102 at the connection between the two pipes 101. Then connect the water diversion hose to the drain pipe 104. If there is water seepage or leakage at the connection between the two pipes 101, according to the principle that water flows to lower places, the water will drip down from the bottom end of the pipe 101 and fall into the collection box 102 for collection. Then, through the drain pipe 104 and the water diversion hose, the water can flow from the collection box 102 into the drainage ditch, preventing the seepage and leakage water of the pipe 101 from dripping onto the electrical equipment, which may lead to a decrease in equipment insulation and even pose a risk of electric shock to personnel.
[0036] Embodiment 2
[0037] Refer to Figure 3 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the flow splitting member 105 includes mounting grooves 105a symmetrically formed in the collection box 102, limiting grooves formed in the mounting grooves 105a, first springs 105b arranged in the limiting grooves, and limiting blocks 105c. The limiting blocks 105c are slidably mounted in the limiting grooves and can be reset by the first springs 105b. There are two flow splitting boxes 105d slidably mounted in the mounting grooves 105a, as well as flow guiding plates 105e and connecting pipes 105f arranged on the flow splitting boxes 105d. The water can flow into the flow splitting boxes 105d through the flow guiding plates 105e.
[0038] Specifically, the first springs 105b are located between the limiting grooves and the limiting blocks 105c. The side of the limiting block 105c away from the first spring 105b is set as an arc surface, and this end extends to the outside of the limiting groove and contacts the top end of the flow splitting box 105d to fix the flow splitting box 105d through the limiting block 105c.
[0039] Furthermore, the bottom ends of the inner walls of the flow splitting boxes 105d and the collection box 102 are both set as inclined surfaces. The flow guiding plates 105e are inclined. The connecting pipes 105f are located above the drain pipes 104, and there is a gap between the connecting pipes 105f and the drain pipes 104. At the same time, the connecting pipes 105f can be connected to the water diversion hoses.
[0040] The remaining structures are the same as those in Embodiment 1.
[0041] Operation process: Before use, install the shunt box 105d by installing the shunt box 105d in the installation groove 105a and pushing the shunt box 105d downward. At this time, the shunt box 105d descends along the installation groove 105a and contacts the top of the limit block 105c. As the shunt box 105d descends, the limit block 105c is squeezed due to the arc surface, causing the limit block 105c to move deeper into the limit groove. After pushing the shunt box 105d to the bottom of the installation groove 105a, the limit block 105c is reset by the reaction force of the first spring 105b and contacts the top of the shunt box 105d to fix it. Then repeat the above steps to install another shunt box 105d, and then connect the water diversion hose to the connecting pipe 105f. When water drops into the inside of the collection box 102, it also drops on the guide plate 105e. Due to the inclined arrangement of the guide plate 105e, the water will flow into the shunt box 105d, and then through the connecting pipe 105f, the water can enter the water diversion hose and then flow into the drainage ditch. By setting the shunt box 105d and the connecting pipe 105f, multiple drainage layers can be combined with the collection box 102, thereby more effectively dispersing the seepage water and reducing the risk of single-point pressure and blockage.
[0042] Embodiment 3
[0043] Referring to Figure 4 - Figure 6 This is the third embodiment of the present invention. The difference between this embodiment and the above embodiments is that the extension member 204 includes a rotating plate 204a rotatably installed in the placement groove 201, a groove 204b opened on the rotating plate 204a, an extension plate 204c slidably installed in the groove 204b, and a sloping plate 204d and a second spring 204e used in cooperation with the extension plate 204c.
[0044] Specifically, the top of the rotating plate 204a is set as an arc surface, and rectangular grooves are opened on both sides of the inner wall of the collection box 102, and the rectangular grooves are located between the placement grooves 201.
[0045] Furthermore, a square groove is opened in the groove 204b, and the sloping plate 204d and the second spring 204e are both arranged in the square groove. The second spring 204e enables the sloping plate 204d to be reset, and the square groove is located between the extension plate 204c and the groove 204b.
[0046] Furthermore, the second spring 204e is located between the sloping plate 204d and the square groove, the side of the sloping plate 204d close to the extension plate 204c is set as an inclined surface, and the top of the support block 203 is set as an arc surface.
[0047] The remaining structures are the same as those in Embodiment 2.
[0048] Operation process: Before use, rotate and tilt the rotating plate 204a, and then pull the support block 203 outwards so that one end of the support block 203 is connected to another chute 202, and support the rotating plate 204a through the support block 203 (as Figure 6 shown). After the rotating plate 204a is tilted, the extension plate 204c will slide downwards under the action of gravity and extend outwards from the rotating plate 204a and be located between the rectangular grooves. At this time, the inclined plate 204d is no longer squeezed and can be reset by the reaction force of the second spring 204e, and the top end of the inclined plate 204d will be at the same horizontal line as the extension plate 204c to block the extension plate 204c, thereby preventing water droplets from dripping on both sides of the pipeline 101, and the accidentally dripping water droplets will also be blocked by the rotating plate 204a. The inclined rotating plate 204a and the extension plate 204c cause the water droplets to enter the collection box 102 from the rectangular grooves, thus effectively preventing the water droplets dripping from both sides of the pipeline 101 from falling onto the electrical equipment. At the same time, pushing the extension plate 204c backwards can squeeze the inclined plate 204d to make it move deeper into the square groove, so that the extension plate 204c can be reset. Then push the support block 203 back to its original position and rotate the rotating plate 204a to complete the reset.
