Description

Technical Field

[0001] The invention relates to the technical field of tank inner wall cleaning, in particular to a high-pressure jet tank inner wall cleaning device. Background Art

[0002] Oil tanks are important equipment for storing various types of oil products and are commonly used in the oil processing and chemical industries. Oil tanks are usually cleaned by high-pressure jets, which pressurize water through a high-pressure water pump and increase the water temperature through a heating system to produce high-pressure hot water jets. This jet of hot water can quickly soften and dissolve the oil stains adhering to the tank, thereby improving the cleaning efficiency. The high-pressure water flow can penetrate into the tiny gaps on the inner wall of the tank, remove dirt that is difficult to reach with conventional cleaning methods, achieve deep cleaning, and facilitate the cleaning of the inner wall of the tank.

[0003] Reference is made to a Chinese patent document with publication number CN118142991A, publication date June 7, 2024, and titled A tank truck cleaning arm and a tank truck cleaning device, comprising a main body, a spray arm for spraying and cleaning inside a tank truck, and an extension mechanism for expanding or retracting the spray arm, the spray arm comprising a second sub-arm, one end of the second sub-arm being fixedly connected and connected to a spray head. The spray arm can be expanded, and the cleaning liquid is sprayed onto the inner wall of the tank body through the spray arm and the spray head.

[0004] With respect to the above-mentioned related technologies, when cleaning a tank body with an arc-shaped inner wall, since the positions of the nozzles and the spray arms of most existing devices are fixed, it is necessary to adjust the position of the nozzles by adjusting the vertical position of the spray arms and the degree of expansion of the spray arms, which increases the difficulty and complexity of the operation and also affects the cleaning efficiency of the device; and the expansion range of the spray arms is limited, which also limits the adjustment range of the inclination of the nozzles. For a tank body with other connecting structures (such as reinforced blades) on the inner wall, the nozzles in the above-mentioned devices are always inclined at a downward angle. When the reinforced blades are placed horizontally, it is difficult for the nozzles in the above-mentioned devices to clean the bottom surface of the reinforced blades. It is also difficult to perform effective targeted cleaning on the connection between the inner wall of the tank body and the reinforced blades, resulting in certain areas in the tank body being unable to be directly washed by high-pressure water flow, forming cleaning dead corners. Summary of the invention

[0005] In view of this, the present invention provides a high-pressure jet tank inner wall cleaning device, which aims to solve the technical problems in the prior art that it is difficult to adjust the nozzle direction of the nozzle, the adjustment range of the nozzle inclination angle and the limited movement range of the nozzle.

[0006] In order to solve the above technical problems, the present invention provides a high-pressure jet tank inner wall cleaning device, which adopts the following technical scheme: a high-pressure jet tank inner wall cleaning device, comprising a vertical rod extending into the tank body and a control member for controlling the vertical rod to rotate around its own axis, and also comprising a connecting frame, two cross bars, two telescopic rods, a mounting block and a nozzle module arranged on the left side wall of the mounting block; the connecting frame is arranged at the bottom of the vertical rod, and the right ends of the two cross bars are fixedly connected with a rotating shaft 1 and a rotating shaft 2 in sequence, and the rotating shaft 1 and the rotating shaft 2 are rotatably connected to the top and bottom of the connecting frame in sequence, and the connecting frame is provided with an adjusting member for controlling the rotating shaft 2 to rotate around its own axis; the two telescopic rods correspond one-to-one to the two cross bars and the telescopic rods are slidably sleeved on the left end of the cross bar, and the cross bar is provided with a telescopic member for controlling the sliding of the telescopic rod, and the left ends of the two telescopic rods are fixedly connected with a rotating shaft 3 and a rotating shaft 4 in sequence, and the rotating shaft 3 and the rotating shaft 4 are rotatably connected to the top and bottom of the mounting plate in sequence.

[0007] By adopting the above technical solution, the adjusting member controls the rotation of the second rotating shaft to ensure that the two cross bars can maintain their positions and ensure the normal operation of the device; when the two telescopic members synchronously control the movement of the telescopic rods, the distance between the mounting block and the connecting frame can be changed, and the position of the mounting block and the nozzle module in the horizontal direction can be adjusted; when one of the telescopic rods is extended or retracted, since the rotation of the second rotating shaft is restricted by the adjusting member, the inclination angle of the lower cross bar and the telescopic rod remains unchanged, the upper cross bar and the telescopic rod gradually tilt, the inclination angle of the mounting block changes, and the spraying direction of the nozzle module on the mounting block changes.

[0008] The device can better clean the inner wall of the tank body with an eccentrically set tank mouth, and the mounting block and the nozzle module are close to the inner wall of the tank body, thereby weakening the negative influence of the distance between the nozzle module and the inner wall of the tank body on the water flow flushing effect. The flexibility of the device can be improved, and the situation in which the existing device is difficult to adjust the direction of the nozzle of the nozzle module can be improved. In particular, the tank body often has an arc-shaped inner wall. Changing the direction of the nozzle of the nozzle of the nozzle module can more effectively flush the arc-shaped inner wall. For the tank body with other connecting structures on the inner wall, changing the direction of the nozzle of the nozzle of the nozzle module can target the connection between the connecting structure and the inner wall of the tank body, so that the flushing effect is better, the operation is simple, and the operation difficulty is reduced.

[0009] Furthermore, when the adjusting member controls the rotation of the second rotating shaft, the position of the mounting block is changed, so that the mounting block moves as a whole along an arc path, which is convenient for cleaning the arc-shaped inner wall in the tank body, which is not only conducive to the nozzle module being close to the inner wall of the tank body, but also can avoid the situation where the mounting block conflicts with the inner wall of the tank body as much as possible. Compared with the prior art, when cleaning the arc-shaped inner wall, this structure does not need to adjust the vertical position and the horizontal position of the mounting block by adjusting the two structures of the vertical rod and the telescopic rod. The vertical position and the horizontal position of the mounting block can be synchronously adjusted by only controlling the rotation of the second rotating shaft of the adjusting member, which can further improve the flexibility of the device, and the device is easy to operate and reduces the difficulty of operation.

[0010] The adjusting member continuously controls the rotation of the second rotating shaft, and the mounting block moves to the lower right as a whole. The mounting block continuously approaches the connecting frame and the vertical rod in the horizontal direction, so as to reduce the horizontal width of the device and facilitate the device to be placed in the tank or taken out from the tank.

[0011] Optionally, the bottom of the vertical rod is fixedly connected to a mounting frame, the top of the connecting frame is fixedly connected to a rotating shaft five, the rotating shaft five is rotatably connected to the mounting frame, and the mounting frame is provided with a rotating member for controlling the rotating shaft five to rotate around its own axis.

[0012] By adopting the above technical solution, the connecting frame and the structure on the connecting frame are rotated around the central axis of the rotating shaft five, which can expand the moving range of the mounting block. When the device is applied to a tank body with an eccentrically arranged tank mouth, it is ensured that the device can comprehensively clean the inner wall of the tank body, so that the nozzle module is as close to the inner wall of the tank body as possible, and the negative influence of the distance between the nozzle module and the inner wall of the tank body on the cleaning effect is weakened, which can improve the cleaning effect of the device.

[0013] Optionally, the rotating member includes a rotating motor connected to the mounting frame, a worm is connected to the output end of the rotating motor, a worm wheel is fixedly connected to the top of the mounting frame, and the worm is meshed with the worm wheel.

[0014] By adopting the above technical solution, a worm gear device is used as a control device, which is beneficial to maintaining the stability of the mechanical device, is suitable for precision control, and has a compact structure and occupies a small space.

[0015] Optionally, the nozzle module includes a rotating nozzle, which is arranged in the middle of the left side of the mounting block, and the rotating nozzle rotates under the action of its own spray water flow.

[0016] By adopting the above technical solution and using a rotating nozzle, the jet water flow of the rotating nozzle can cover a wider area during the rotation process, making the cleaning more uniform, reducing the existence of cleaning dead corners, and improving the cleaning efficiency. The rotating nozzle rotates autonomously under the action of the water flow, reducing the need for the operator to adjust the direction of the rotating nozzle nozzle and reducing the difficulty of operation.

[0017] Optionally, a grille capable of connecting the left and right sides of the mounting block is provided on the mounting block, and a plurality of blades are circumferentially arranged on the circumferential side wall of the rotating nozzle.

[0018] By adopting the above technical solution, during the rotation of the rotary nozzle, the blades are driven to rotate, blowing the gas on the left side of the mounting block to the right side of the mounting block, which is beneficial for the external structure to extract the oil and gas in the tank body, improves the situation where oil and gas gather near the rotary nozzle in the existing device, and is beneficial to improving the safety of operation.

[0019] Optionally, the nozzle module further includes two direct nozzles sequentially connected to the top and bottom of the left side of the mounting frame.

[0020] By adopting the above technical solution, the combination of the rotary nozzle and the direct nozzle can give full play to the advantages of different types of nozzles to achieve a more efficient and thorough cleaning effect, especially for the cleaning of stubborn stains and the cleaning of the connection between the inner wall of the tank and other connecting structures in the tank. The direct nozzle has a better targeted cleaning effect.

[0021] Optionally, the adjusting member includes an electric push rod, a horizontally placed connecting rod 1 is connected to the top of the right side of the connecting frame, a connecting rod 2 is fixedly connected to the rotating shaft 2, and both ends of the electric push rod are hinged to the connecting rod 1 and the connecting rod 2 in sequence.

[0022] Optionally, the telescopic member includes an electric push rod, and both ends of the electric push rod are hinged to the cross bar and the telescopic rod in sequence.

[0025] In summary, the present invention includes the following beneficial technical effects: 1. The device can conveniently change the inclination angle of the mounting block and the nozzle module, which is convenient for cleaning the inner wall of the tank body, improving the complicated operation of adjusting the nozzle nozzle direction in the past, and can adjust the inclination angle of the nozzle module in a variety of ways to reduce the difficulty of operation; it is convenient to make the mounting block and the nozzle module close to or away from the connecting frame, which is convenient for reducing the distance between the nozzle module and the inner wall of the tank body, thereby ensuring that the water flow sprayed by the nozzle module can wash away the stains attached to the inner wall of the tank body, and it is also convenient for the device to be inserted into the tank body or taken out of the tank body; for the tank body with an eccentrically arranged tank mouth, the tank body is provided with an arc-shaped inner wall, and the inner wall of the tank body is connected to other connecting structures, the rotated nozzle module has a better cleaning effect, thereby improving the cleaning efficiency of the device.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0032] The following is combined with Figure 1 -Attached Figure 7 The present invention is described in further detail.

[0033] The embodiment of the present invention discloses a high-pressure jet tank inner wall cleaning device. Figures 1 to 7 A high-pressure jet tank inner wall cleaning device comprises a vertical rod 1, a control member 2, a connecting frame 3, a mounting block 4, a nozzle module 5, an adjustment module 6 and a rotation module 7. The control member 2 controls the rotation of the vertical rod 1, the connecting frame 3 is arranged at the bottom of the vertical rod 1, the mounting block 4 is arranged on the connecting frame 3, the nozzle module 5 is arranged on the mounting block 4, the adjustment module 6 can adjust the position of the mounting block 4 relative to the connecting frame 3 and the inclination angle of the mounting block 4, and the rotation module 7 is used to adjust the position of the connecting frame 3 relative to the vertical rod 1 and the inclination angle of the connecting frame 3, thereby improving the flexibility of the device, improving the restriction of the existing device on the nozzle direction of the nozzle module 5, so that the nozzle module 5 can clean the inner wall of the tank from all aspects and improve the cleaning effect.

[0034] Reference Figure 1 The vertical rod 1 is placed vertically, and the vertical rod 1 can extend into the tank through the tank opening on the tank body to facilitate cleaning the inside of the tank body. The control member 2 can control the vertical rod 1 to rotate the vertical rod 1 around its own axis, thereby changing the orientation of other structures on the vertical rod 1, so as to facilitate multi-directional cleaning of the inside of the tank body.

[0035] Reference Figure 1 Specifically, the control component 2 includes a support frame 21, a control motor 22, a gear 1 23 and a gear 2 24. The support frame 21 is sleeved on the outer wall of the tank mouth on the tank body to play a supporting role. The control motor 22 is fixedly connected to the support frame 21, the gear 1 23 is fixedly sleeved on the output end of the control motor 22, and the gear 2 24 is fixedly sleeved on the vertical rod 1, and the gear 1 23 is meshed with the gear 2 24. Start the control motor 22 to drive the gear 1 23 to rotate, and then drive the gear 2 24 and the vertical rod 1 to rotate. It has the advantage of more stable power transmission and compact structure, and can achieve transmission requirements in a limited space.

[0036] Reference Figure 1 and Figure 2The connecting frame 3 is vertically arranged at the bottom of the vertical rod 1. The connecting frame 3 is used to provide support for other structures to facilitate the assembly of the structure. The mounting block 4 is arranged on the connecting frame 3. The nozzle module 5 is connected to the mounting block 4. The mounting block 4 is arranged. By adjusting the position and tilt angle of the mounting block 4, the position and tilt angle of the nozzle module 5 are adjusted, which is convenient for operation.

[0037] Reference Figure 1 and Figure 3 Specifically, the nozzle module 5 includes a rotating nozzle 51 and a direct nozzle 52 .

[0038] Reference Figure 3 and Figure 4 The rotating nozzle 51 is connected to the middle part of the left side of the mounting block 4. A plurality of nozzles are provided on the rotating nozzle 51. The plurality of nozzles are arranged along the circumference of the rotating nozzle 51. Under the action of the water flow sprayed from the nozzles, the rotating nozzle 51 rotates around its own axis, so that the sprayed water flow can cover a wider area, making the cleaning more uniform, reducing the existence of cleaning dead corners, and improving the cleaning efficiency. The rotating nozzle 51 rotates autonomously under the action of the water flow, reducing the difficulty of operation and the workload of the operator.

[0039] Reference Figure 3 and Figure 4 There are two direct spray nozzles 52, which are sequentially connected to the top and bottom of the left side of the mounting block 4, and the nozzles of the direct spray nozzles 52 are perpendicular to the left side wall of the mounting frame 71. The direct spray nozzles 52 have a better effect on cleaning stubborn stains and are more suitable for cleaning the connection gaps between the inner wall of the tank and other connection structures in the tank.

[0040] The combined use of the rotating nozzle 51 and the direct nozzle 52 can give full play to the advantages of different types of nozzles to achieve a more efficient and thorough cleaning effect. For the inner walls of tanks of different shapes and different types of stains, a more suitable nozzle type can be selected for targeted cleaning, which can also reduce the workload of operators and reduce the difficulty of operation.

[0041] Reference Figure 3 and Figure 4 Furthermore, a plurality of blades 511 are connected to the circumferential side wall of the rotating nozzle 51, and the plurality of blades 511 are evenly arranged along the circumference of the rotating nozzle 51. A grille 512 is provided on the mounting block 4, and the through holes on the grille 512 can connect the left and right sides of the mounting block 4. As the rotating nozzle 51 rotates, the plurality of blades 511 rotate accordingly, and the airflow on the left side of the mounting block 4 passes through the grille 512 and flows to the right side of the mounting block 4.

[0042] Reference Figure 1 , Figure 2 and Figure 3The adjustment module 6 is arranged between the connecting frame 3 and the mounting block 4, and is used to adjust the position of the mounting block 4 relative to the connecting frame 3 and the inclination angle of the mounting block 4, so that the mounting block 4 and the nozzle module 5 can be close to the inner wall of the tank body, which is convenient for cleaning the inner wall of the tank body, weakening the negative effect of the distance between the nozzle module 5 and the inner wall of the tank body on the water flow cleaning force, changing the angle of the nozzle of the nozzle module 5, facilitating the adjustment of the flushing angle of the water flow, facilitating the cleaning of the inner wall of the tank body, reducing the existence of cleaning dead angles, and reducing the difficulty of operation.

[0043] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the adjustment module 6 includes two cross bars 61, two telescopic bars 62, a rotation axis 1 63, a rotation axis 2 64, an adjustment member 65, a telescopic member 66, a rotation axis 3 67 and a rotation axis 4 68.

[0044] Reference Figure 1 , Figure 2 and Figure 3 , two cross bars 61 are arranged in parallel and spaced apart, two telescopic rods 62 correspond to the two cross bars 61 one by one, and the telescopic rods 62 are slidably sleeved on the left end of the cross bars 61. Rotation axis 1 63 and rotation axis 2 64 are sequentially connected to the right ends of the two cross bars 61, and rotation axis 1 63 and rotation axis 2 64 are sequentially rotatably connected to the top and bottom of the connecting frame 3. Adjustment member 65 is arranged between rotation axis 2 64 and the connecting frame 3, and adjustment member 65 is used to control the rotation of rotation axis 2 64. Two telescopic members 66 are provided, and two telescopic members 66 correspond to the two cross bars 61 one by one, and telescopic members 66 are arranged between cross bars 61 and telescopic rods 62, and telescopic members 66 are used to control the reciprocating movement of telescopic rods 62. Rotation axis 3 67 and rotation axis 4 68 are sequentially connected to the left ends of the two telescopic rods 62, and rotation axis 3 67 and rotation axis 4 68 are sequentially rotatably connected to the top and bottom of the right side of mounting block 4.

[0045] The telescopic rod 62 is slidably connected to the cross bar 61. The position of the telescopic rod 62 relative to the cross bar 61 is adjusted, and the distance between the top and bottom of the mounting block 4 and the connecting frame 3 is further adjusted, so that the position of the mounting block 4 relative to the connecting frame 3 and the inclination angle of the mounting block 4 can be adjusted. The rotating shaft 1 63, the rotating shaft 2 64, the rotating shaft 3 67 and the rotating shaft 4 68 arranged here have the function of ensuring that the device can operate normally to avoid the inability to adjust the mounting block 4 due to structural abutment.

[0046] The adjustment member 65 limits the rotation of the second rotating shaft 64. If the second rotating shaft 64 is not limited here, the lower cross bar 61 and the telescopic rod 62 rotate downward under the action of their own gravity, affecting the normal operation of the device. Therefore, the adjustment member 65 has the effect of stabilizing the structure.

[0047] Furthermore, the distance between the rotation axis 1 63 and the rotation axis 2 64 is equal to the distance between the rotation axis 3 67 and the rotation axis 4 68. When the total length of the upper cross bar 61 and the telescopic rod 62 is equal to the total length of the lower cross bar 61 and the telescopic rod 62, the mounting block 4 is arranged parallel to the connecting frame 3, which is convenient for adjusting the device.

[0048] Reference Figure 5 When in use, the two telescopic members 66 synchronously adjust the two telescopic rods 62 to move back and forth, which can change the distance between the mounting block 4 and the connecting frame 3, that is, change the position of the mounting block 4 relative to the connecting frame 3 in the horizontal direction, so that the mounting block 4 and the nozzle module 5 can be close to the inner wall of the tank, and the distance between the nozzle module 5 and the inner wall of the tank can be reduced, ensuring that the water flow sprayed by the nozzle module 5 can wash away the stains attached to the inner wall of the tank. In addition, only one mounting block 4 is provided on the device, which is more suitable for cleaning the tank body with an eccentric tank mouth.

[0049] Reference Figure 5 When one of the telescopic rods 62 is extended or retracted, since the rotation of the second rotating shaft 64 is limited by the adjusting member 65, the inclination angles of the lower crossbar 61 and telescopic rod 62 remain unchanged, and the upper crossbar 61 and telescopic rod 62 gradually tilt. If the upper telescopic rod 62 is extended or retracted to the left or right, the mounting block 4 rotates around the central axis of the rotating shaft 4 68, and the mounting block 4 is tilted; if the lower telescopic rod 62 is extended or retracted to the left or right, the mounting block 4 rotates around the central axis of the rotating shaft 3 67. In summary, when only one telescopic rod 62 changes position, the position of the mounting block 4 changes slightly, but the inclination angle of the mounting block 4 can be adjusted in a wider range, thereby adjusting the nozzle direction of the nozzle module 5 on the mounting block 4.

[0050] It can enhance the flexibility of the device and improve the situation in which the existing device is difficult to adjust the direction of the nozzle of the nozzle module 5. In particular, the tank body is often provided with a curved inner wall. Changing the direction of the nozzle of the nozzle module 5 can more effectively flush the curved inner wall. For the tank body with other connecting structures on the inner wall, changing the direction of the nozzle of the nozzle of the nozzle module 5 can specifically flush the connection between the connecting structure and the inner wall of the tank body, resulting in better flushing effect, simple operation, and reduced operating difficulty.

[0051] Reference Figure 5 and Figure 6 When the adjusting member 65 is started, the adjusting member 65 controls the rotation of the second rotating shaft 64, which can change the positions of the cross bar 61, the telescopic rod 62 and the mounting block 4. At this time, the position of the connecting frame 3 remains unchanged, the rotating shaft 1 63 and the rotating shaft 2 64 rotate, and the moving path of the mounting block 4 is an arc.

[0052] The position of the mounting block 4 relative to the connecting frame 3 in the vertical and horizontal directions can be changed, which is particularly suitable for cleaning the curved inner wall of the tank body, so that the curvature of the moving path of the mounting block 4 is similar to the curvature of the curved inner wall of the tank body; compared with the prior art, when cleaning the curved inner wall, the structure does not need to adjust the vertical position and the horizontal position of the mounting block 4 by adjusting the two structures of the vertical rod 1 and the telescopic rod 62. Only the adjusting member 65 is required to control the rotation of the rotating shaft 2 64 to synchronously adjust the vertical position and the horizontal position of the mounting block 4, which can further enhance the flexibility of the device, and the device is easy to operate and reduces the difficulty of operation.

[0053] Reference Figure 5 and Figure 6 , and the adjustment member 65 can control the rotating shaft 2 64 to rotate the cross bar 61 and the telescopic rod 62 downward. At this time, the lateral width of the cross bar 61, the telescopic rod 62 and the connecting frame 3 is reduced, which is conducive to placing the device into the tank or taking the device out of the tank.

[0054] Reference Figure 5 Specifically, the adjusting member 65 includes an electric push rod, a horizontally placed connecting rod 1 651 is fixedly connected to the top of the right side of the connecting frame 3, a connecting rod 2 652 is fixedly connected to the circumferential side wall of the rotating shaft, and both ends of the electric push rod are hinged to the ends of the connecting rod 1 651 and the ends of the connecting rod 2 652 in sequence. The electric push rod can be remotely controlled by an electrical signal, which is convenient for controlling the rotation of the rotating shaft, has a compact structure, and can save space.

[0055] Reference Figure 5 Specifically, the telescopic member 66 includes an electric push rod, and both ends of the electric push rod are hinged to the cross bar 61 and the telescopic rod 62 in sequence.

[0056] Reference Figure 2 and Figure 7 The rotating module 7 is arranged between the connecting frame 3 and the vertical rod 1. The rotating module 7 is used to adjust the position of the connecting frame 3 relative to the vertical rod 1 and the inclination angle of the connecting frame 3, further expanding the adjustment range of the device, improving the flexibility of the device, and allowing the nozzle module 5 to be close to the inner wall of the tank.

[0057] Reference Figure 2 and Figure 7 Specifically, the rotating module 7 includes a mounting frame 71, a rotating shaft 5 72 and a rotating member 73. The mounting frame 71 is fixedly connected to the bottom of the vertical rod 1, the rotating shaft 5 72 is fixedly connected to the top of the connecting frame 3, the rotating shaft 5 72 is rotatably connected to the mounting frame 71, and the rotating member 73 is arranged between the mounting frame 71 and the connecting frame 3. The rotating member 73 is used to control the rotation of the connecting frame 3 and make the connecting frame 3 rotate around the central axis of the rotating shaft 5 72.

[0058] Reference Figure 7, so that the connecting frame 3 rotates around the central axis of the rotating shaft 5 72, which can expand the moving range of the mounting block 4. When the device is applied to a tank body with an eccentrically arranged tank mouth, it is ensured that the device can comprehensively clean the inner wall of the tank body, so that the nozzle module 5 is as close to the inner wall of the tank body as possible, and the negative influence of the distance between the nozzle module 5 and the inner wall of the tank body on the cleaning effect is weakened, which can improve the cleaning effect of the device.

[0059] Reference Figure 7 Specifically, the rotating member 73 includes a rotating motor 731, a worm 732 and a worm wheel 733. The rotating motor 731 is fixedly connected to the mounting frame 71, the worm 732 is fixedly connected to the output end of the rotating motor 731, the worm wheel 733 is fixedly connected to the top of the connecting frame 3, and the worm 732 is meshed with the worm wheel 733. Using the worm wheel 733 and the worm 732 device as the control device is conducive to maintaining the stability of the mechanical device, suitable for precision control, and has a compact structure and occupies a small space.

[0060] The implementation principle of a high-pressure jet tank inner wall cleaning device according to an embodiment of the present invention is as follows: Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 , the vertical rod 1, the connecting frame 3 and the mounting block 4 vertically pass through the tank opening of the tank body and extend into the tank body. The adjusting member 65 is started to control the rotation of the second rotating shaft 64, and the cross bar 61 is unfolded. According to the cleaning of different positions in the tank body, the position and tilt angle of the mounting block 4 and the nozzle module 5 are adjusted.

[0061] When cleaning the circumferential inner wall of the tank, the rotating nozzle 51 is used, and when cleaning the connection gap of the inner wall of the tank, the direct nozzle 52 is used. When the mounting block 4 is far away from the inner wall of the tank, the mounting block 4 can be brought close to the inner wall of the tank by adjusting the positions of the two telescopic rods 62 and controlling the adjustment of the rotating shaft 5 72. When the inner wall of the tank is arc-shaped, the inclination angle of the mounting block 4 and the nozzle module 5 can be changed by the telescopic member 66, the adjusting member 65 and the rotating member 73, so as to facilitate cleaning.

[0062] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
