[0048] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present invention. However, it is apparent to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known in the art are not described.

[0049] The applicant believes that when the gate of the existing gate intercepting device is in a raised state for a long time, the flow of water may cause some silt to accumulate directly below the gate. When the gate subsequently falls, it may cause the gate to fail to completely fall to the bottom, which may easily affect the sealing and interception effect of the gate. At the same time, when the gate is in a dropped state for a long time, impurities and debris driven by the flow of water, such as silt, branches, etc., may pile up and get stuck on one side of the gate, which may easily affect the subsequent raising of the gate and the release of water flow, etc., and there are certain hidden dangers and shortcomings.

[0050] Embodiment 1:

[0051] To this end, the applicant proposed a water conservancy construction interception device and a method of use, such as Figure 1-Figure 7 As shown, it includes a gate 1, a gate 2, a lifting mechanism 3 and a dirt blocking mechanism 4.

[0052] The gate 2 is arranged in the gate port 1 , the lifting mechanism 3 is connected to the gate 2 , and the dirt blocking mechanism 4 is arranged on one side of the gate 2 .

[0053] In the present application, the structures and principles of the gate 1, the gate 2 and the lifting mechanism 3 can refer to the prior art. The pollution blocking mechanism 4 is arranged on the side of the gate 2 close to the water inlet to block impurities and debris such as mud, branches, etc., so as to avoid the influence of these impurities and debris on the lifting and lowering of the gate 2, thereby extending the service life of the gate 2 and protecting the normal sealing use of the gate 2.

[0054] like Figure 1-Figure 7 As shown, the dirt blocking mechanism 4 includes a mounting component 5, an external dirt blocking component 6 and an internal dirt blocking component 11, the mounting component 5 includes a frame 501, a mounting slide groove 502, a stop plate 503, a fixing hole 504 and a fixing bolt 505, the external dirt blocking component 6 includes a dirt blocking frame 601 and a dirt blocking rod assembly 7, and the internal dirt blocking component 11 includes an internal dirt blocking platform 1101 and a moving assembly 12.

[0055] Among them, the frame 501 is installed on the water inlet side of the gate 1, the installation slot 502 is opened in the frame 501, the abutment plate 503 is installed at the bottom of the frame 501, the trash blocking frame 601 is adapted to the installation slot 502 and abuts against the abutment plate 503, and the trash blocking rod assembly 7 is arranged on the trash blocking frame 601 for blocking trash.

[0056] In the present application, a plurality of fixing holes 504 are provided, and the plurality of fixing holes 504 are correspondingly opened on the side walls of the frame body 501 and the trash-blocking frame 601, and the fixing bolts 505 are adapted to the fixing holes 504, and are used to lock and fix the frame body 501 and the trash-blocking frame 601. During installation, the trash-blocking frame 601 is slid into the installation slide groove 502 along the inner wall of the installation slide groove 502 until the bottom of the trash-blocking frame 601 abuts against the surface of the abutment plate 503, and then the fixing bolts 505 are screwed into the fixing holes 504, so that the frame body 501 and the trash-blocking frame 601 can be locked and fixed.

[0057] In addition, a through groove is provided at the bottom of the frame body 501 to prevent mud and sand from entering the installation chute 502 and accumulating in the installation chute 502, thereby affecting the installation of the trash-blocking frame 601 and the frame body 501.

[0058] In this embodiment, the trash-blocking bar assembly 7 includes a plurality of fixed trash-blocking bars 8, which are welded to the trash-blocking frame 601 at a predetermined interval to intercept debris in the water body.

[0059] like Figure 1-Figure 7 As shown, in this embodiment, the internal pollution blocking platform 1101 is arranged in the gate 1, and the moving component 12 is used to drive the internal pollution blocking platform 1101 to move. The moving component 12 includes an internal moving part 13, and the internal moving part 13 includes a moving cavity 1301, a connecting inner plate 1302, an outer connecting plate 1303, a moving rod 1304, a return spring 1305, a guide rail 1306, a guide groove 1307 and a leakage groove 1308.

[0060] Among them, the moving cavity 1301 is opened in the inner pollution blocking platform 1101, the connecting inner plate 1302 is slidably set in the moving cavity 1301, the outer connecting plate 1303 is connected to the frame 501, the moving rod 1304 is connected between the outer connecting plate 1303 and the connecting inner plate 1302 and is slidably connected to the inner pollution blocking platform 1101, the reset spring 1305 is set on the outside of the moving rod 1304 and connected between the connecting inner plate 1302 and the inner wall of the moving cavity 1301, which is used to drive the inner pollution blocking platform 1101 to move, the guide rail 1306 is abutted against the inner wall of the gate 1 and connected to the outer connecting plate 1303, and the guide groove 1307 is opened at the bottom of the inner pollution blocking platform 1101 and is adapted to the guide rail 1306, which is used to cooperate and guide the moving direction of the inner pollution blocking platform 1101.

[0061] In this embodiment, the guide rail 1306 and the guide groove 1307 are engaged and can move relative to each other, and the movement of the inner pollution blocking platform 1101 can be restricted so that it can only move linearly on the inner wall of the gate 1. A sliding hole adapted to the moving rod 1304 is provided on the inner pollution blocking platform 1101, and the sliding hole is connected to the moving cavity 1301. The leakage groove 1308 runs through the connection between the outer connecting plate 1303 and the guide rail 1306, and is used to move the inner pollution blocking platform 1101 when the inner pollution blocking platform 1101 moves. 101 and the outer connecting plate 1303 for discharging impurities such as mud and sand. The inner moving part 13 also includes a connecting rod guide rail, a connecting rod slider, a driven connecting rod and two hinged seats. The connecting rod guide rail is installed on the side of the gate 2 close to the outer pollution-blocking component 6. The connecting rod slider is adapted to the connecting rod guide rail. The two hinged seats are correspondingly installed on the connecting rod slider and the inner pollution-blocking platform 1101. The driven connecting rod is correspondingly hinged between the two hinged seats. The connecting rod guide rail is set to a predetermined length, and limit plates are set at both ends to limit the moving position of the connecting rod slider.

[0062] When the gate 2 is opened, since the outer connecting plate 1303 is fixedly connected to the frame 501, the inner dirt blocking platform 1101 can be driven to move to the side close to the gate 2 under the action of the reset spring 1305. During the process, the inner plate 1302 is connected to the inner wall of the moving cavity 1301 and moves relative to each other. The inner dirt blocking platform 1101 moves relative to the moving rod 1304 through the sliding hole. On the one hand, it can push and shovel the mud and other impurities directly under the gate 2, thereby pushing the mud and other impurities away from the bottom of the gate 2. In addition, the inner dirt blocking platform 1101 can stay under the gate 2 under the action of the reset spring 1305 to protect the bottom of the gate 2, thereby preventing the mud and other impurities in the water from staying and accumulating directly under the gate 2 when the water flows subsequently. During the process, the connecting rod slider moves on the connecting rod guide rail and drives the driven connecting rod to move.

[0063] When the gate 2 is closed, during the process, the gate 2 drives the connecting rod guide rail to move in the opposite direction on the connecting rod slider until the connecting rod slider abuts against the limit plate. At this time, the driven connecting rod on the connecting rod guide rail starts to move, and drives the internal pollution-blocking platform 1101 to move in the opposite direction through the hinge seat on the internal pollution-blocking platform 1101, until the internal pollution-blocking platform 1101 is away from the bottom of the gate 2. Then the gate 2 falls and abuts against the inner wall of the gate 1. During the process, the reset spring 1305 is deformed, and the guide rail 1306 and the internal pollution-blocking platform 1101 move relative to each other through the guide groove 1307. The internal pollution-blocking platform 1101 can push out impurities such as mud and sand accumulated on the guide rail 1306 from the leakage groove 1308, and can also push out impurities such as mud and sand between the internal pollution-blocking platform 1101 and the external pollution-blocking component 6, so as to avoid affecting the movement of the internal pollution-blocking platform 1101.

[0064] In the present application, the inner pollution blocking platform 1101 is used to cooperate with the moving component 12 to shovel dirt and protect the area directly below the gate 2. The upper surface of the inner pollution blocking platform 1101 is set at a predetermined inclination angle to form a pollution blocking slope, which is used to cooperate with the external pollution blocking component 6 to block sludge and debris. At the same time, a guide frame 16 is embedded on the inner wall of the gate 1, and the guide frame 16 is set corresponding to the gate 2, which can improve the stability of the gate 2 when sliding.

[0065] Embodiment 2:

[0066] The applicant further discovered that, although the welding arrangement of the fixed trash-blocking rod 8 and the trash-blocking frame 601 in the first embodiment of the present application can improve the stability of the overall structure, there are also some problems. For example, the integrated welding arrangement may cause a certain part to be deformed or damaged, and the entire part often needs to be replaced, which may easily lead to waste of materials. Moreover, if it is replaced separately, it needs to be cut and then welded, which may cause inconvenience in replacement. Therefore, the trash-blocking rod assembly 7 in this embodiment includes an adjustable trash-blocking rod 9.

[0067] like Figure 8 As shown, the adjustable dirt-blocking bar 9 includes an adjustment slot 901 , a dirt-blocking bar body 903 , a threaded joint 904 , a locking nut 905 , a support column 906 , a drainage slot 902 and a through slot 907 .

[0068] Among them, the adjustment groove 901 is opened on the dirt-blocking frame 601, the dirt-blocking rod body 903 is inserted into the adjustment groove 901, the threaded joint 904 is connected to one end of the dirt-blocking rod body 903 and is set through the adjustment groove 901, the locking nut 905 is compatible with the threaded joint 904, the abutment column 906 is welded on the outer wall of the dirt-blocking rod body 903 and abuts against the inner wall of the dirt-blocking frame 601, and is used to cooperate with the locking nut 905 to lock the dirt-blocking rod body 903 and the dirt-blocking frame 601, the sewage groove 902 is opened through the outer wall of the sewage frame 601 and is connected with the adjustment groove 901, and the through groove 907 is opened through the bottom of the dirt-blocking frame 601 and is connected with both the sewage groove 902 and the adjustment groove 901, and is used to cooperate with the sewage groove 902 to discharge impurities in the adjustment groove 901.

[0069] In this embodiment, the trash frame 601 is connected to the adjustable trash blocking rod 9 by abutting, and each part is separately arranged. When the trash frame 601 or a certain adjustable trash blocking rod 9 is deformed or damaged, it can be replaced separately. If a certain adjustable trash blocking rod 9 is damaged, it is only necessary to unscrew the corresponding locking nut 905, and then rotate the corresponding adjustable trash blocking rod 9 ninety degrees to pull it out from the trash frame 601. It has the advantages of simple operation and easy replacement. At the same time, the setting of the adjustment groove 901 can facilitate the user to install different numbers of trash blocking rod bodies 903 according to actual conditions, so that the distance between two adjacent trash blocking rod bodies 903 can meet the actual dirt blocking needs, etc. The setting of the sewage groove 902 and the through groove 907 can prevent impurities from accumulating in the sewage groove 902 and affecting the installation of the dirt blocking rod body 903.

[0070] When in use, fix the trash blocking frame 601 to the frame body 501, then insert a suitable number of trash blocking rod bodies 903 into the adjustment groove 901, adjust the spacing between adjacent trash blocking rod bodies 903, and then rotate the trash blocking rod body 903 ninety degrees so that the support column 906 is stuck on the inner wall of the trash blocking frame 601, and then screw the locking nut 905 onto the threaded joint 904 and abut against the outer wall of the trash blocking frame 601.

[0071] Embodiment three:

[0072] The applicant further discovered that although the trash-blocking rod assembly 7 provided in the first and second embodiments of the present application can block impurities such as tree branches at the water inlet, the blocking effect is limited. Although the blocking gap can be adjusted by providing a greater number of trash-blocking rod bodies 903 in the second embodiment, too many trash-blocking rod bodies 903 may also result in problems such as difficulty in installation and adjustment. Therefore, a matching trash-blocking member 10 is provided.

[0073] like Figure 9-14 As shown, the mating trash-blocking member 10 is installed on the trash-blocking rod assembly 7 to cooperate with the trash-blocking rod assembly 7 to block trash. The mating trash-blocking member 10 includes a trash-blocking plate 1001 or a trash-blocking hook 1002 .

[0074] Among them, the trash blocking plate 1001 is installed on the trash blocking rod assembly 7 with a predetermined length, the end face of the trash blocking plate 1001 along the extension direction of the trash blocking rod assembly 7 is set in a cone shape, and a plurality of trash blocking hooks 1002 are provided. The plurality of trash blocking hooks 1002 are welded to the trash blocking rod assembly 7 at a predetermined interval, and the plurality of trash blocking hooks 1002 on two adjacent trash blocking rod assemblies 7 are arranged in an intermittent and cross manner.

[0075] In this embodiment, the trash blocking plate 1001 and the trash blocking hook 1002 are both arranged perpendicular to the support column 906, and the setting of the trash blocking plate 1001 can relatively close the trash blocking frame 601, which can further reduce the impurities and debris such as branches and mud entering the gate 1 when the gate 2 is closed. When the gate 2 is opened, the corresponding trash blocking plate 1001 can be opened by rotating the corresponding trash blocking rod. It is easy to operate, and can adjust the size and direction of a single trash blocking spacing, as well as the size and direction of the entire trash blocking spacing, which can further adapt to actual use needs, and can be convenient for users to set and adjust according to actual conditions.

[0076] The setting of the dirt-blocking hook 1002 can intercept impurities and debris such as tree branches that are about to enter the gate 1 in the dirt-blocking gap formed between two adjacent dirt-blocking bars, and can self-clean the impurities and debris that are against or stuck in the dirt-blocking gap and the corresponding dirt-blocking bar by rotating the corresponding dirt-blocking bar, thereby ensuring the dirt-blocking efficiency and avoiding the dirt-blocking gap from being blocked by impurities and debris, thereby protecting the normal use of the external dirt-blocking component 6 and the normal passage of water.

[0077] In addition, the trash blocking plate 1001 and the trash blocking hook 1002 can be used separately or installed together, and can be set according to specific usage conditions.

[0078] Embodiment 4:

[0079] The applicant further discovered that although the internal moving part 13 in the first embodiment of the present application can move with the internal pollution blocking platform 1101, the movement effect is limited and may be affected by factors such as the size of the water flow, thereby affecting the opening and closing of the gate 2, etc., so another moving component 12 is set.

[0080] like Figure 15-16 As shown, the moving assembly 12 includes a bottom outer moving member 14 , and the bottom outer moving member 14 includes a connecting column 1401 , a moving head 1402 and a movable frame 1403 .

[0081] Among them, the connecting column 1401 is connected to the side of the inner dirt blocking platform 1101 close to the outer dirt blocking component 6, and the moving head 1402 is installed at the end of the connecting column 1401 away from the inner dirt blocking platform 1101, which is used to push and pull the inner dirt blocking platform 1101 to move, and the movable frame 1403 is correspondingly arranged on the dirt blocking frame 601 to facilitate the movement of the dirt blocking frame 601.

[0082] In this embodiment, the arrangement of the connecting column 1401 and the moving head 1402 can facilitate the user to move the internal dirt blocking platform 1101 manually or by external mechanical equipment, thereby avoiding the influence of factors such as the size of the water flow on the movement of the internal dirt blocking platform 1101. In order to facilitate the disassembly and assembly of the dirt blocking frame 601, a movable frame 1403 is adapted to be arranged on the dirt blocking frame 601. The same is true for the top external moving part 15 described below. If the dirt blocking frame 601 is considered to be easy to disassemble and assemble with the frame body 501, it is also necessary to be adapted to be arranged on the dirt blocking frame 601.

[0083] like Figure 17-Figure 18 As shown, the moving assembly 12 includes a top outer moving member 15 , and the top outer moving member 15 includes a connecting rope 1501 , a guide box 1502 , a guide wheel 1503 and a rope groove 1504 .

[0084] Among them, the connecting rope 1501 is connected to a side of the inner dirt blocking platform 1101 close to the outer dirt blocking component 6, the guide box 1502 is installed on the frame 501, the guide wheel 1503 is installed in the guide box 1502, the rope groove 1504 is opened on the guide wheel 1503 and is adapted to the connecting rope 1501, and two guide holes adapted to the connecting rope 1501 are opened on the guide box 1502, which are used to block dirt and guide the direction of the connecting rope 1501.

[0085] In this embodiment, the connecting rope 1501 can be a steel wire rope. The connecting rope 1501 is guided by the guide box 1502, the guide wheel 1503, the rope groove 1504 and the guide hole, which can improve the stability of the internal pollution-blocking platform 1101 during movement. At the same time, the end of the connecting rope 1501 can be pulled by manpower or external mechanical equipment to achieve the driven movement of the internal pollution-blocking platform 1101.

[0086] In addition, the outer moving member 14 at the bottom and the outer moving member 15 at the top can be used separately, or can be used in conjunction with installation. They can be arranged manually or automatically, or automatically or automatically, and can be arranged according to specific circumstances.

[0087] Based on the above technical solution, the specific working process of the present invention is as follows:

[0088] If the construction requires flow interception, first use the moving component 12 to drive the inner pollution blocking platform 1101 to move towards the direction close to the outer pollution blocking component 6 to ensure that the bottom of the gate 2 is exposed, and then use the lifting mechanism 3 to drive the gate 2 to descend until the bottom of the gate 2 is in close contact with the inner wall of the gate 1. If the construction is completed and the water flow needs to be restored, first use the lifting mechanism 3 to drive the gate 2 to rise. When the gate 2 is separated from the upper end of the inner pollution blocking platform 1101, use the moving component 12 to drive the inner pollution blocking platform 1101 to move away from the outer pollution blocking component 6 to hide the bottom of the gate 2.

[0089] In addition, the specific components such as the moving assembly 12 and the external dirt-blocking component 6 can be set and operated according to the specific installation and use conditions.

[0090] As above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention defined in the appended claims.
