[0046] The drainage holes 2 are communicated with the drainage pipe 31;
[0047] The specific working process of the device is as follows: when rainwater washes the dust on the photovoltaic module into the drainage groove 1, due to the slow water flow and the gravity of the impurities, the heavier precipitated impurities gradually settle at the bottom of the drainage groove 1; due to the fact that the drainage holes 2 are arranged at the bottom of the drainage groove 1 and are multiple, the precipitated impurities fall into the drainage pipe 31 below through the drainage holes 2; the conveying mechanism 32 arranged in the drainage pipe 31 operates, continuously conveying the precipitated impurities falling into the drainage pipe 31 to one end of the drainage pipe 31, so that the precipitated impurities in the drainage groove 1 are cleaned in time, and the normal drainage function of the drainage groove 1 is maintained.
[0048] As a preferred scheme of the utility model, referring to Figure 5The conveying mechanism 32 is a spiral conveying shaft, more specifically, the spiral conveying shaft is made of stainless steel or plastic material to prevent rusting and damage in a humid and impurity environment, and a motor 33 is installed at the end of the spiral conveying shaft to drive the rotation of the spiral conveying shaft; when the sediments fall into the drain pipe 31, the spiral conveying shaft rotates under the driving of the motor 33, and the special shape of the spiral blade causes the sediments to be subjected to a component force in the tangential direction of the spiral blade during rotation, which pushes the sediments to move along the spiral blade to the end of the drain pipe 31, thereby achieving the conveying of the sediments.
[0049] As a preferred scheme of the utility model, referring to Figure 5 , the spiral conveying shaft is composed of a plurality of split components, the split components can adopt standard parts of the same specification for easy production and installation, the length of each split component can be determined according to actual installation and transportation convenience, the split components are connected through flanges or inserted, during installation, the split component at the end of the motor 33 is first installed and fixed in the drain pipe 31, and then the other split components are sequentially connected and installed in place through flanges, to ensure that the shaft centers of the split components are on the same straight line.
[0050] The spiral conveying shaft is composed of split components, which can be flexibly disassembled and assembled according to actual needs during installation and maintenance, when a split component is damaged, only the component needs to be disassembled and replaced, without the need to replace the entire spiral conveying shaft, which does not affect the normal operation of the entire conveying system.
[0051] As a preferred scheme of the utility model, referring to Figure 1 、 Figure 2 and Figure 5 , the drain pipe 31 is composed of a plurality of pipe sections, the pipe sections of the drain pipe 31 can be made of standard length pipe materials, such as 2-4 meters per section, and the pipe sections are connected through socket joints or flanges; when connected through socket joints, sealant is applied at the socket to ensure tight connection and prevent leakage; when connected through flanges, sealing pads and bolts are used for fastening, during installation, the pipe section close to one end of the drain groove 1 is first installed and fixed, and then the other pipe sections are sequentially connected and installed in place, to ensure that the shaft center of the entire drain pipe 31 is on the same straight line and accurately communicates with the drain hole 2 on the drain groove 1.
[0052] The drain pipe 31 composed of a plurality of pipe sections can better adapt to drain grooves 1 of different lengths and shapes, and meet various complex installation requirements by adjusting the number of pipe sections and the connection mode.
[0053] As a preferred scheme of the utility model, the drain hole 2 is communicated with a communication pipe one 4.
[0054] The drain mechanism 3 further comprises a communication pipe two 34 communicated with the drain pipe 31.
[0055] Referring to Figure 2 and Figure 5 , the communication pipe one 4 is inserted with the communication pipe two 34;
[0056] The insertion installation mode of the communication pipe one 4 and the communication pipe two 34 is relatively simple and easy to operate, and if the drain tank 1 or the drain pipe 31 needs to be overhauled during maintenance, the communication pipe one 4 and the communication pipe two 34 can be conveniently separated, thereby improving the efficiency of the maintenance work.
[0057] As a preferred scheme of the utility model, referring to Figure 2 and Figure 5 , the communication pipe two 34 is flared at one end close to the drain tank 1, so that the communication pipe one 4 can be more conveniently inserted into the communication pipe two 34; and the communication pipe two 34 covers the communication pipe one 4, more specifically, the communication pipe two 34 is relatively thick with respect to the communication pipe one 4, so that the communication pipe two 34 covers the communication pipe one 4, and the purpose of such a setting is to prevent sewage flowing along the communication pipe one 4 from flowing out along the gap between the communication pipe one 4 and the communication pipe two 34; if the communication pipe one 4 is set to be relatively thick, the sewage is extremely likely to flow out along the gap between the two during the downward flow of the sewage, thereby affecting the surrounding environment.
[0058] As a preferred scheme of the utility model, referring to Figure 2 , the utility model further comprises a connecting mechanism 5 for connecting the drain tank 1 and the drain pipe 31; the number of the connecting mechanism 5 can be set according to the length of the drain pipe 31, and in the embodiment, the connecting mechanism 5 is provided with two, which are respectively arranged at two ends of the drain pipe 31;
[0059] Referring to Figure 3 , Figures 5-8 , the connecting mechanism 5 comprises:
[0060] A fixed part one 51 is fixed to the bottom of the drain tank 1; the fixed part one 51 can adopt a metal material, such as a steel plate; the fixed part one 51 is firmly fixed to the bottom of the drain tank 1 by means of welding or bolt connection;
[0061] A fixed part two 52 is fixed to the top of the drain pipe 31; the fixed part two 52 can also adopt a metal material, such as Figure 2 As shown, the fixed part two 52 is in an inverted U shape and the cross section is circular, so as to more smoothly rotate the locking part 54;
[0062] The fixed part one 51 is provided with a notch 53 for the fixed part two 52 to extend into, the notch 53 is in a cuboid shape, and the bottom of the notch 53 is flared, so as to conveniently extend the fixed part two 52;
[0063] The connecting mechanism 5 further comprises:
[0064] A locking member 54 is rotatably connected to the first fixing member 51, and more specifically, an opening is formed in the middle of the side of the notch 53, and the locking member 54 is installed in the opening; the rotatable connection has the following structure: a pin shaft is fixed to one end of the locking member 54, and the pin shaft is rotatably connected to the inner wall of the opening; or a pin shaft is fixed to the inner wall of the opening, and the locking member 54 is rotatably connected to the pin shaft; in order to keep the locking member 54 in a drooping state without external force, a counterweight 57 is installed at the bottom of the locking member 54;
[0065] The other end of the locking member 54 includes an inclined portion 55 and a supporting portion 56;
[0066] When the second fixing member 52 moves upward and extends into the notch 53, the second fixing member 52 presses the inclined portion 55 to rotate the locking member 54, and more specifically, the angle of the inclined portion 55 is generally between 30-60 degrees, when the second fixing member 52 moves upward, the second fixing member 52 generates a force on the inclined portion 55, which is perpendicular to the inclined portion 55, and the force can be decomposed into a vertical upward force and a horizontal outward force, the horizontal outward force pushes the locking member 54 to rotate, and after the second fixing member 52 moves upward and separates from the inclined portion 55, the locking member 54 returns to the initial position under the action of gravity;
[0067] When the first fixing member 51 and the second fixing member 52 are fixed, the supporting portion 56 bears the second fixing member 52, and more specifically, the supporting portion 56 is in a horizontal state, when the blowdown pipe 31 is completely released, the second fixing member 52 is in contact with the supporting portion 56, and cannot drive the locking member 54 to rotate, thereby preventing the second fixing member 52 from separating;
[0068] The operation process of the connecting mechanism 5 of the device is as follows: after the blowdown pipe 31 and the spiral conveying shaft are connected, the entire blowdown mechanism 3 is pushed upward, the second fixing member 52 is inserted into the notch 53, and the communication pipe one 4 is inserted into the communication pipe two 34, in this process, the second fixing member 52 applies a horizontal component force to the inclined portion 55 of the locking member 54, which makes the locking member 54 rotate around the rotatable connection point of the first fixing member 51, when the second fixing member 52 is completely inserted into the notch 53, the supporting portion 56 of the locking member 54 is just below the second fixing member 52, which bears the second fixing member 52, thereby realizing the fixed connection of the drain tank 1 and the blowdown pipe 31.
[0069] As a preferred scheme of the utility model, referring to Figure 1 , the inner diameter of the inlet end of the blowdown hole 2 gradually decreases in the direction of the water flow, when the water flow carries the sediments into the blowdown hole 2, the water flow speed increases at the blowdown hole 2 due to the gradually decreasing inner diameter of the inlet end of the blowdown hole 2, according to the principle of fluid mechanics, the increased flow speed increases the carrying capacity of the water flow to the sediments, so that the sediments are more easily carried into the blowdown pipe 31, and the probability of the sediments blocking the blowdown hole 2 is reduced.
[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
