[0021] The following is combined with Figure 1 To Attachment Figure 3 And specific embodiments further describe the present application in detail.

[0022] In the present application, the above-mentioned sewer suction pipe protection device includes: a mounting frame body 10, a wellhead support assembly 20 and a suction pipe clamping assembly 30, wherein the mounting frame body 10 is in the shape of a ring, and the mounting frame body 10 is composed of a first half ring and a second half ring that are symmetrically spliced, and the joint between the first half ring and the second half ring is fixedly connected by bolts, so that the mounting frame body 10 is a complete circular ring or an elliptical ring, and the outer diameter of the ring of the mounting frame body 10 is larger than the diameter of a conventional suction pipe and smaller than the inner diameter of a conventional sewer wellhead; the number of wellhead support assemblies 20 is several, and the several wellhead support assemblies 20 are evenly distributed around the axis of the mounting frame body 10. Specifically, the wellhead support assemblies 20 arranged on the mounting frame body 10 The number of support assemblies 20 depends on the diameter of the mounting frame body 10 and the inner diameter of the sewer wellhead. The larger the diameter and inner diameter are, the more the number of wellhead support assemblies 20 can be appropriately increased to ensure that the mounting frame body 10 can be stably connected to the sewer wellhead; the wellhead support assembly 20 includes a first adjustment portion 21 and a clamping block 22, wherein the first adjustment portion 21 is connected to the mounting frame body 10 in cooperation, and the first adjustment portion 21 is located on at least one side of the outer side of the mounting frame body 10 ring. The clamping block 22 is used to support the upper side of the edge of the sewer wellhead so that the mounting frame body 10 is fixed in the wellhead, and the first adjustment portion 21 is used to adjust the clamping block 22 away from or close to the wellhead (i.e., the sewer wellhead). The number of the sewage suction pipe clamping assemblies 30 is several, and the sewage suction pipe clamping assemblies 30 are spaced around the axis of the mounting frame body 10 and the wellhead support assemblies 20 (that is, the sewage suction pipe clamping assemblies 30 are arranged between adjacent wellhead support assemblies 20), and the number of the sewage suction pipe clamping assemblies 30 depends on the diameter of the mounting frame body 10 and the diameter of the sewage suction pipe. The larger the diameter and the diameter, the more the number of the sewage suction pipe clamping assemblies 30 can be appropriately increased to ensure that the sewage suction pipe clamping assemblies 30 are stably connected to the sewage suction pipe; the sewage suction pipe clamping assembly 30 includes a second adjusting portion 31 and a clamping piece 32, wherein the first The second adjustment part 31 is connected to the mounting frame body 10, and the above-mentioned clip 32 is set on at least one side of the second adjustment part 31 located on the inner side of the mounting frame body 10. The clip 32 includes an arc-shaped plate 321 connected to the second adjustment part 31 and a flexible pad 322 made of elastic materials such as rubber or sponge. The arc-shaped plate 321 is arc-shaped on one side facing the axial direction of the mounting frame body 10, and the above-mentioned flexible pad 322 is pasted on the arc-shaped surface. The flexible pad 322 can completely cover the arc-shaped surface to prevent the suction pipe from rubbing against the side edges of the clip 32 when contacting the suction pipe. The second adjustment part 31 is used to adjust the clip 32 to be close to or away from the axis of the mounting frame body 10 so as to clamp or loosen the suction pipe.

[0023] When using the above device, the mounting frame body 10 is suspended in an open sewer manhole, and the position of the clamping block 22 is adjusted by the first adjusting portion 21 to move the clamping block 22 in a direction away from the axis of the mounting frame body 10 until the clamping block 22 can contact the edge of the sewer manhole. The clamping block 22 supports and fixes the mounting frame body 10 at the sewer manhole, so that it cannot slide down the well or fall into the well or cannot be easily removed from the well (here, it means that the clamping block 22 is not released from the edge of the sewer manhole by adjusting the first adjusting portion 21). and adjusting the second adjusting portion 31 to make the clips 32 gather toward the axis of the mounting frame body 10. When the range enclosed by the arcuate surfaces of the clips 32 of the plurality of suction pipe clamping assemblies 30 is slightly larger than the diameter of the suction pipe, the suction pipe is extended or pulled out under the sewer through the range enclosed by the arcuate surfaces to adjust the preset position of the suction pipe. When the suction pipe is adjusted to the optimal position, continue to adjust the second adjusting portion 31 to make the clips 32 gather toward the suction pipe, and stop adjusting immediately when the clips 32 can clamp the suction pipe.

[0024] The above device can achieve at least the following technical effects:

[0025] The plurality of wellhead support assemblies 20 arranged on the outside of the mounting frame body 10 can be adjusted according to the diameters of different sewer wellheads, so that the device can adapt to conventional sewer wells of different diameters; the plurality of sewage suction pipe clamping assemblies 30 arranged on the inside of the mounting frame body 10 can fix conventional sewage suction pipes of different diameters at the axis of the mounting frame body 10, so as to prevent the sewage suction pipe from being worn against the edge of the wellhead due to shaking or length adjustment during dredging operations. The flexible pad 322 can prevent the sewage suction pipe from being worn against the arc plate 321, and increase the contact area between the arc plate 321 and the sewage suction pipe, thereby extending the service life of the sewage suction pipe and increasing the firmness of fixing the sewage suction pipe, eliminating the safety hazards caused by wear and shaking of the sewage suction pipe.

[0026] In addition, this application also provides some more specific implementations to improve the above device.

[0027] Furthermore, in order to facilitate the adjustment of the position of the block 22 and improve the installation or disassembly efficiency of the above device, the above first adjustment part 21 includes a first fixed seat 211 and an adjusting screw 212, and the mounting frame body 10 is provided with a positioning hole 11 around the axis (that is, the positioning hole 11 is a long hole opened around the axis along the side of the first half ring and the second half ring); the first fixed seat 211 is slidably connected or fixedly connected to the mounting frame body 10, and a screw hole is opened on the first fixed seat 211 along the direction of the depth extension of the positioning hole 11, and the adjusting screw 212 passes through the above positioning hole 11 and is connected with the screw hole on the first fixed seat 211, and the above block 22 is provided at one end of the adjusting screw 212 away from the axis of the mounting frame body 10.

[0028] When using the above device, rotating the adjusting screw rod 212 in one direction can move the block 22 toward the edge of the wellhead. When the block 22 is supported on the edge of the wellhead, the adjusting screw rod 212 is stopped. At this time, the adjusting screw rod 212 supports the block 22 under the reaction force, so that the block 22 is fixed to the edge of the wellhead. When the above device needs to be disassembled, the adjusting screw rods 212 of each wellhead support assembly 20 are rotated in reverse order in a specific order to move the block 22 toward the axis of the mounting frame body 10. After the block 22 has no supporting effect on the edge of the wellhead, the above device can be removed from the wellhead.

[0029] Furthermore, in order to improve the matching degree between the above-mentioned device and the wellhead and the installation stability, the above-mentioned first adjustment part 21 also includes a stop nut 213, and a first card groove 2111 is arranged on one side of the first fixed seat 211 around the axis of the mounting frame body 10, and the first card groove 2111 is engaged and slidably connected with the mounting frame body 10 (that is, the first half ring and the second half ring pass through the first card groove 2111 and can slide relative to the first fixed seat 211), the stop nut 213 is connected with the adjusting screw 212, and a groove is also arranged on the inner side of the first fixed seat 211, and the width of the groove is not less than the outer diameter of the stop nut 213.

[0030] When the edge of the wellhead is incomplete or not flat enough, slide the first fixing seat 211 along the mounting frame body 10, adjust the position of the clamping block 22, so that the clamping block 22 is evenly stressed and the mounting frame body 10 is kept as horizontal as possible; turn the stop nut 213, and when the stop nut 213 enters the groove and is resisted by the groove, the stop nut 213 presses the first clamping groove 2111 outward, and the first fixing seat 211 is fixed to a certain place of the mounting frame body 10. At this time, the first fixing seat 211 can be prevented from sliding randomly, so that the mounting frame body 10 remains stable.

[0031] Furthermore, in order to enable the block 22 to adapt to the edge of the wellhead and ensure the support stability, the block 22 includes a side plate 221 and a top plate 222. The side plate 221 is vertically downward and fixed to one end of the adjusting screw rod 212, and the top plate 222 is horizontally fixed to the upper side of the side plate 221 and forms an angle with the side plate 221.

[0032] When the adjusting screw rod 212 is rotated to fix the block 22 to the edge of the wellhead, the angle between the side plate 221 and the top plate 222 can be clamped on the edge of the wellhead, so that the block 22 is firmly fixed at the wellhead, which can prevent the suction pipe from jumping during the suction process and causing the block 22 to separate from the edge of the wellhead.

[0033] Furthermore, to facilitate the adjustment of the position of the clip 32, the second adjustment portion 31 includes a second fixed seat 311 and a telescopic adjustment rod 312. The second fixed seat 311 is slidably connected or fixedly connected to the mounting frame body 10. The telescopic adjustment rod 312 includes a sleeve 3121 and a screw 3122. One end of the sleeve 3121 is rotatably connected to the second fixed seat 311. A thread for cooperating with the screw 3122 is machined inside the sleeve 3121. The screw 3122 is cooperatingly connected to the sleeve 3121, and the arc plate 321 is provided at one end of the screw 3122 away from the second fixed seat 311.

[0034] When using the above device, the sleeve 3121 is rotated in one direction to move the screw 3122 toward the axis of the mounting frame until the screw 3122 enables the arc surface of each clip 32 to clamp the suction pipe, and the sleeve 3121 is stopped from rotating. At this time, the suction pipe is fixed at the center of the wellhead by each suction pipe clamping assembly 30.

[0035] Furthermore, in order to enable the clip 32 to fit the sewage suction pipe and make the sewage suction pipe evenly stressed, a second card slot 3111 is provided on the outer side of the second fixed seat 311, and the second card slot 3111 is snap-connected and slidably connected to the mounting frame body 10 (that is, the first half ring and the second half ring pass through the second card slot 3111 and can slide relative to the second fixed seat 311).

[0036] When the diameter of the sewage suction pipe is large, the second fixing seat 311 is slid so that the arc surface of the clamp 32 can be as ring-shaped as possible. At this time, the clamp 32 is adjusted to clamp the sewage suction pipe by adjusting the second adjusting portion 31, so as to ensure that the sewage suction pipe is evenly stressed and firmly fixed, and prevent the sewage suction pipe from deforming or detaching from the clamp 32.

[0037] Furthermore, in order to avoid safety hazards caused by violent shaking of the sewage suction pipe during the dredging process, one end of the above-mentioned sleeve 3121 is connected to the buffer shock-absorbing rod 313, and one end of the buffer shock-absorbing rod 313 is hingedly provided with a hinged ear seat 314, and the hinged ear seat 314 is provided with a convex shaft 3141 on the side away from the hinged part, and the convex shaft 3141 is rotatably connected to the inner side of the second fixed seat 311; one end of the screw rod 3122 is hinged to the arc plate 321.

[0038] When the sewage suction pipe shakes violently due to the water hammer effect during the dredging process, the buffer shock-absorbing rod 313 is stretched or compressed by force, and the hinged ear seat 314 can rotate relative to the second fixed seat 311 to reduce the swing amplitude of the sewage suction pipe; when the sewage suction pipe fluctuates up and down due to shaking, the telescopic adjustment rod 312, the hinged ear seat 314 and the clamping piece 32 can rotate relative to each other, so that the arc surface of the clamping piece 32 is always in close contact with the side wall of the sewage suction pipe, while reducing the fluctuation amplitude of the sewage suction pipe, avoiding the formation of a gap between the arc surface of the clamping piece 32 and the sewage suction pipe, so that the sewage suction pipe is always fixed between the clamping pieces 32 during the dredging process, preventing the sewage suction pipe from detaching from the sewage suction pipe clamping assembly 30 and colliding with the wellhead due to shaking.

[0039] The above-mentioned sewer suction pipe protection device is applied to the following sewer dredging method to improve the fit between the suction pipes of different diameters of the suction truck and the sewer wells of different diameters, thereby improving the safety of the sewer dredging operation.

[0040] The method specifically comprises the following steps:

[0041] Step 1: Determine whether the sewer is blocked. If yes, call a sewage suction truck to the wellhead of the sewer to be desilted;

[0042] Step 2: Remove the manhole cover to fully expose the edge of the manhole cover used to support the manhole cover, and monitor the concentration of harmful gases at the manhole cover and the distance between the location to be desilted and the manhole cover;

[0043] Step 3: Adjust the first adjusting portion 21 according to the diameter of the wellhead, so that the clamping block 22 is supported on the edge of the wellhead, and fix the mounting frame body 10 in the wellhead;

[0044] Step 4: Pass the suction pipe of the sewage suction truck through the mounting frame body 10 and extend it into the sewer. When the length of the suction pipe extending into the sewer reaches the distance between the position to be desilted and the sewer wellhead, stop extending the suction pipe, and adjust the second adjustment part 31 so that the clamping piece 32 clamps the suction pipe, and fixes the suction pipe at the axis of the mounting frame body 10;

[0045] Step 5: Start the sewage suction truck to dredge the sewer through the sewage suction pipe.

[0046] Specifically, in combination with the judgment results of the degree of sewer blockage in the above steps, a suction truck with appropriate power is called to perform dredging operations; the sewer manhole cover is removed, and harmful gases are released and monitored to prevent the concentration of harmful gases in the well from exceeding the standard and causing physical harm to the operators; after normal ventilation, a professional distance measuring instrument is used or a technician goes down the well to measure the distance from the position to be dredged (i.e. the sewer blockage position) to the sewer wellhead, which is the distance the suction pipe needs to extend below the sewer wellhead; the above-mentioned sewer suction pipe protection device is installed at the wellhead, and then the suction pipe is passed through the above-mentioned mounting frame body 10 and extended into the sewer, and when the extension length value reaches the distance between the position to be dredged and the sewer wellhead, the above-mentioned sewer suction pipe protection device is operated to fix the suction pipe at the center of the wellhead (for specific operating steps, please refer to the operating method of the sewer suction pipe protection device in the above-mentioned specific embodiments).

[0047] The above-mentioned sewer dredging method uses the above-mentioned sewer suction pipe protection device, which can improve the fit between the suction pipes of different diameters of the suction truck and the sewer wells of different diameters, and improve the safety of sewer dredging operations using suction pipes.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
