Description

Technical Field

[0001] The present application relates to the technical field of cable fixing, and in particular to a cable fixing device for power survey. Background Art

[0002] The cable fixing device for power survey is a device for cable retraction and extension. Taking the cable fixing device for power survey as an example, most of the existing power survey cables are wound on the bracket for transportation.

[0032] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0033] To solve the above technical problems, please refer to Figures 1-4 As shown, the present application proposes a cable fixing device for power survey (cables are not shown in the accompanying drawings), which can reduce the difficulty of cable retraction and deployment, and is less likely to cause workers to fall down, thereby improving the safety of the cable fixing device for power survey.

[0034] Figure 1 This is a schematic structural diagram of a cable fixing device for power survey provided in one embodiment of the present application; Figure 2 This is a schematic diagram of the exploded structure of a cable fixing device for power survey provided in one embodiment of the present application; Figure 3 Schematic diagram of the exploded structure of the support shaft 210 and the locking assembly 300 in one embodiment of the present application; Figure 4It is a schematic diagram of the exploded structure of the adjustment component 400 and the locking component 300 in one embodiment of the present application.

[0035] Reference Figure 1 and Figure 2 In some embodiments of the present application, a cable fixing device for power survey is used to fix a cable for power survey, and includes a support assembly 100, a winding assembly 200, a locking assembly 300, and an adjusting assembly 400. The support assembly 100 has a mounting groove 130; the winding assembly 200 is rotatably connected to the support assembly 100, and the winding assembly 200 is at least partially installed in the mounting groove 130. The winding assembly 200 can wind the cable; the locking assembly 300 is installed on the support assembly 100 and / or the winding assembly 200, and the locking assembly 300 can lock The winding assembly 200; the adjusting assembly 400 is installed on the supporting assembly 100, the adjusting assembly 400 is connected to the locking assembly 300, and the adjusting assembly 400 can adjust the locking assembly 300; wherein, the locking assembly 300 has a locked state and an unlocked state, in the locked state, the locking assembly 300 locks the winding assembly 200, and the winding assembly 200 and the supporting assembly 100 are relatively fixed in at least one rotation direction; in the unlocked state, the locking assembly 300 unlocks the winding assembly 200, and the winding assembly 200 can rotate relative to the supporting assembly 100.

[0036] Based on the above-mentioned embodiment of the present application, the support assembly 100 is the supporting and bearing part of the entire device, and the winding assembly 200, the locking assembly 300 and the adjusting assembly 400 are all directly or indirectly mounted on the support assembly 100. The winding assembly 200 can wind and store the cable, the locking assembly 300 can lock and unlock the winding assembly 200, and the adjusting assembly 400 can adjust the state of the locking assembly 300, such as adjusting the locking assembly 300 from a locked state to an unlocked state. Specifically, the winding assembly 200 can be at least partially rotatably connected to the mounting groove 130 of the support assembly 100, and the cable can be retracted or released by rotating the winding assembly 200. The locking assembly 300 can lock the winding assembly 200. In this way, after the cable is retracted or released, the cable can be prevented from being further retracted or released by locking the winding assembly 200. While ensuring work efficiency, the difficulty of retracting and releasing the cable is reduced, and it is less likely to cause workers to fall, thereby improving the safety of the cable fixing device for power survey. The state of the locking assembly 300 can be adjusted by the adjustment assembly 400. Specifically, the locking assembly 300 can be switched between a locked state and an unlocked state by the adjustment assembly 400. The embodiments of the present application can reduce the difficulty of cable retraction and deployment, making it less likely that workers will fall down, thereby improving the safety of the cable fixing device for power surveys.

[0037] It should be noted that the retraction and extension of the cable is achieved through the winding assembly 200. Specifically, the cable can be retracted by rotating the winding assembly 200 in a first direction, and the cable can be extended by rotating it in a second direction. The first direction and the second direction are two opposite directions. A manual drive structure or an electric drive structure can be installed on the winding assembly 200 as needed to increase the retraction and extension speed of the winding assembly 200. The manual drive structure may include a crank and other structures, and the winding assembly 200 is driven to rotate by rotating the crank; the electric drive structure may include a motor, and the winding assembly 200 is driven to rotate directly or indirectly by the motor. The motor may be a stepping motor to improve the winding accuracy; when the motor is indirectly connected, it can be connected to the winding assembly 200 in conjunction with a transmission mechanism.

[0038] It should be noted that the locking assembly 300 can be installed separately on the support assembly 100. The locking assembly 300 can switch between the locked state and the unlocked state by connecting or abutting with the winding assembly 200. Specifically, the locking assembly 300 can be driven by the adjustment assembly 400 to achieve connection or abutment with the winding assembly 200.

[0039] The locking assembly 300 can also be installed separately on the winding assembly 200. The locking assembly 300 can switch between the locked state and the unlocked state by connecting or abutting with the support assembly 100. Specifically, the locking assembly 300 can be driven by the adjustment assembly 400 to achieve connection or abutment with the winding assembly 200.

[0040] The locking assembly 300 can also be partially installed on the supporting assembly 100 and partially installed on the winding assembly 200. The locking assembly 300 can switch between the locked state and the unlocked state through the connection or abutment of these two parts. Specifically, the locking assembly 300 can be driven by the adjusting assembly 400 to achieve connection or abutment to the winding assembly 200.

[0041] Among the above three implementation modes, this application takes the third one as an example for detailed description.

[0042] Reference Figure 2 In some embodiments of the present application, the locking assembly 300 is one of a ratchet and pawl mechanism, a top screw mechanism, and a pin hole mechanism.

[0043] Based on the above embodiments of the present application, three implementation methods of the locking assembly 300 are introduced above. The locking assembly 300 of the present application is not limited to the above three methods.

[0044] Among them, the ratchet pawl mechanism has the characteristic of one-way rotation and reverse cut-off. A certain rotation direction of the winding component 200 can be set as the cut-off direction as needed, and the other relative rotation direction is the normal rotation direction. The pawl 320 can be adjusted in conjunction with the adjustment component 400, and the switching between the locked state and the unlocked state can be achieved by driving the pawl 320 close to or away from the ratchet 310.

[0045] The jackscrew mechanism has the characteristics of tightening and locking and loosening and unlocking. When the winding assembly 200 is rotated to a certain position (the cable is reeled in and released as required), the jackscrew mechanism can be used to tighten the winding assembly 200 relative to the jackscrew mechanism, so that the winding assembly 200 cannot continue to rotate, so that the winding assembly 200 is switched from the unlocked state to the locked state. When the cable needs to be reeled in again, the winding assembly 200 can be switched from the locked state to the unlocked state by loosening the jackscrew. The adjustment of the jackscrew mechanism can be achieved through the adjustment assembly 400, and the adjustment assembly 400 can include a knob connected to the jackscrew. The jackscrew mechanism can be specifically installed on the winding assembly 200, and can be tightened to the support assembly 100 by rotating the jackscrew; the jackscrew mechanism can also be installed on the support assembly 100, and can be tightened to the winding assembly 200 by rotating the jackscrew.

[0046] The pin-hole mechanism locks and unlocks through the engagement of the pin holes. When the corresponding pin penetrates both the support assembly 100 and the winding assembly 200, the winding assembly 200 is locked. When the pin is removed or engaged with only one of the support assembly 100 and the winding assembly 200, the winding assembly 200 is unlocked. The insertion and removal of the pin can be controlled by the adjustment assembly 400.

[0047] The corresponding type of locking assembly 300 can be selected as needed, and this application does not impose any restrictions on this.

[0048] Reference Figures 2 to 4 In some embodiments of the present application, the locking assembly 300 is a ratchet and pawl mechanism, comprising a ratchet 310 and at least one pawl 320. The ratchet 310 is mounted on one of the support assembly 100 and the winding assembly 200. The at least one pawl 320 is adapted to the ratchet 310, and the pawl 320 is mounted on the other of the support assembly 100 and the winding assembly 200.

[0049] The adjusting assembly 400 is directly or indirectly connected to the pawl 320 , and the adjusting assembly 400 can drive the pawl 320 to move closer to or away from the ratchet 310 to achieve locking and unlocking of the locking assembly 300 .

[0050] Based on the above-mentioned embodiments of the present application, after the locking assembly 300 is set to a ratchet pawl mechanism, the one-way rotation and reverse cut-off characteristics of the ratchet pawl mechanism can be utilized, and a certain rotation direction of the winding assembly 200 can be set to the cut-off direction as needed, and the other relative rotation direction can be the normal rotation direction. For example, the direction of storing the cable can be the normal rotation direction, and the direction of releasing the cable can be the cut-off direction. When the ratchet pawl mechanism has a cut-off direction, it can be considered to be in a locked state. In this state, the cable can be stored smoothly, and the reverse releasing direction is locked; the direction of releasing the cable can also be set to the normal rotation direction, and the direction of storing the cable can be the cut-off direction. In this locked state, the cable can be released smoothly, and the storage direction is locked; only by destroying the cooperation between the ratchet 310 and the pawl 320 by adjusting the assembly 400 can the locked state be switched to the unlocked state, that is, the state where there is no cut-off direction.

[0051] It should be noted that the adjustment component 400 is used to adjust the pawl 320. When the adjustment component 400 does not interfere with the pawl 320, the pawl 320 can cooperate normally with the ratchet 310. After the adjustment component 400 drives the pawl 320 away from the ratchet 310, the ratchet 310 and the pawl 320 can no longer cooperate normally. At this time, the locked state can be switched to the unlocked state. Conversely, after the adjustment component 400 drives the pawl 320 close to the ratchet 310 and does not interfere with the swing of the pawl 320, the unlocked state can be switched to the locked state.

[0052] It should be noted that the pawl 320 can swing back and forth relative to the ratchet 310 under the action of gravity or an elastic member (not shown in the figure), so that the pawl 320 always has a preload force tending to approach the ratchet 310 (in this application, the pawl 320 approaching the ratchet 310 means that the pawl 320 rotates in the direction of engagement with the ratchet 310, and the pawl 320 moving away from the ratchet 310 means that the pawl 320 rotates in the opposite direction of engagement with the ratchet 310), ensuring the effectiveness of the ratchet pawl mechanism. The adjustment component 400 can overcome the above-mentioned preload force during the adjustment process, so that the pawl 320 can be adjusted to a state away from the ratchet 310 and maintain this state, thereby achieving relative unlocking of the pawl 320, that is, switching the locking component 300 from the locked state to the unlocked state. At this time, the ratchet pawl mechanism in the unlocked state will lose the reverse cutoff feature, facilitating the retraction and release of the cable. The number of pawls 320 is set as needed, and at least one pawl 320 is provided. The drawings in this application are illustrative examples using four pawls 320 as an example.

[0053] Reference Figure 2In some embodiments of the present application, the ratchet 310 is mounted on the winding assembly 200, and the ratchet 310 can rotate with the winding assembly 200; the pawl 320 is mounted on the support assembly 100, and the support assembly 100 is provided with a mounting hole 121 adapted to the winding assembly 200, and the winding assembly 200 is rotatably connected to the mounting hole 121;

[0054] A limiting groove 140 is also provided on the support assembly 100, and the ratchet 310 is at least partially located in the limiting groove 140. The bottom of the limiting groove 140 is connected to the mounting hole 121. A fixing rod 330 is provided at the bottom of the limiting groove 140. The fixing rod 330 is located on the outer peripheral side of the mounting hole 121. The pawl 320 is rotatably connected to the fixing rod 330. The number of the pawls 320 and the fixing rod 330 is the same and corresponds one to one.

[0055] Based on the above-mentioned embodiment of the present application, after the ratchet 310 is installed in the winding assembly 200, the ratchet 310 can be made to rotate relative to the support assembly 100 along with the winding assembly 200. After the pawl 320 is installed on the support assembly 100, the relative rotation mode of the winding assembly 200 and the support assembly 100 can be limited by the cooperation of the pawl 320 and the ratchet 310. Specifically, when the pawl 320 and the ratchet 310 cooperate normally, the relative rotation of the winding assembly 200 and the support assembly 100 has the characteristic of one-way rotation and reverse cutoff. The reverse cutoff characteristic can be utilized to improve the safety of cable retraction or release, and it is not easy for the cable to knock down the staff through inertia. The mounting hole 121 on the support assembly 100 is adapted to the winding assembly 200, and the winding assembly 200 can be rotatably connected to the support assembly 100 through the mounting hole 121. The setting of the limiting groove 140 can be used to accommodate the locking assembly 300, wherein a portion of the winding assembly 200 passes through the mounting hole 121 and is located in the limiting groove 140, and the ratchet 310 can be installed on the portion of the winding assembly 200 located in the limiting groove 140.

[0056] The fixed rods 330 are provided for mounting the pawls 320. The fixed rods 330 can be fixedly connected to the bottom of the limiting slots 140. Each fixed rod 330 is rotatably connected to a pawl 320. When the pawls 320 are provided with elastic members, the elastic members can be torsion springs that can be mounted on the fixed rods 330. The torsion springs can provide a preload force for the pawls 320 to engage with the ratchet wheel 310.

[0057] Reference Figure 3 In some embodiments of the present application, the adjustment assembly 400 includes an adjustment body 410 and an adjustment rod 420. The adjustment body 410 is rotatably connected to the limiting groove 140. The adjustment rod 420 is installed on a side of the adjustment body 410 close to the pawl 320 and extends toward the pawl 320.

[0058] The pawl 320 is provided with an adjustment slot 324 into which the adjustment rod 420 extends. The number of the adjustment rods 420 is the same as the number of the pawls 320 and corresponds one to one. The adjustment slot 324 has a space for the adjustment rods 420 to move relative to each other.

[0059] The rotation of the adjusting body 410 can drive the adjusting rod 420 to move, and the movement of the adjusting body 410 can drive the pawl 320 to move closer to or away from the ratchet 310 .

[0060] Based on the above-described embodiment of the present application, the adjustment body 410 can drive the adjustment rod 420 to move. The adjustment body 410 is rotatably connected to the limiting groove 140. The rotation of the adjustment body 410 can drive the adjustment rod 420 to rotate relative to the limiting groove 140. The adjustment groove 324 on the pawl 320 has a certain amount of clearance, so that there is always a gap between the pawl 320 and the adjustment rod 420 during the swing process of the pawl 320 relative to the ratchet 310. In other words, the adjustment rod 420 does not affect the swing of the pawl 320 in the original state. At this time, the ratchet and pawl mechanism operates according to the original rules. The original state here refers to the state when the adjustment assembly 400 does not interfere with the locking assembly 300. Under the drive of the adjustment body 410, the adjustment rod 420 can force the meshing position of the pawl 320 away from the ratchet 310, completely separating the pawl 320 and the ratchet 310, and changing the operating state of the ratchet 310 and the pawl 320.

[0061] It should be noted that the aforementioned rotation of the adjustment rod 420 relative to the limiting slot 140 refers to the movement of the adjustment rod 420 as a whole relative to the limiting slot 140 along a predetermined arcuate trajectory, and does not involve the adjustment rod 420 rotating on its own. The relative movement of the adjustment rod 420 begins within the adjustment slot 324. After the adjustment rod 420 abuts the inner wall of the adjustment slot 324, it continues to move, driving the meshing portion 322 of the pawl 320 to rotate away from the ratchet wheel 310, until the pawl 320 is restrained to a position where it no longer contacts the ratchet wheel 310, thereby achieving a state switch.

[0062] It should be noted that the adjustment groove 324 can be configured as a V-shaped groove as needed. In this case, the adjustment groove 324 includes a clearance sub-groove adapted to the adjustment rod 420 and an assembly sub-groove adapted to the elastic member. The clearance sub-groove is provided to make way for the adjustment rod 420. When the adjustment rod 420 is relatively stationary, the shape of the clearance sub-groove adapts to the interlaced swinging trajectory of the adjustment rod 420 and the pawl 320.

[0063] Reference Figure 4 In some embodiments of the present application, the adjustment body 410 includes a screwing portion 411 and an adjustment connection portion 412 , the adjustment connection portion 412 is connected to the screwing portion 411 , and the adjustment connection portion 412 is located on a side of the screwing portion 411 close to the pawl 320 ;

[0064] A first snap ring 413 is provided on the outer peripheral side of the adjustment connection portion 412 , and a second snap ring matched with the first snap ring 413 is provided on the inner side of the limiting groove 140 .

[0065] Based on the above-mentioned embodiments of the present application, the screwing portion 411 is a part that is convenient for staff to screw and adjust. The screwing portion 411 can be a structure that is convenient for manual adjustment, or a polygonal structure that is convenient for tool adjustment. When a large force needs to be applied, the adjustment can be assisted by a wrench or other structure, or an adjustment lever or an adjustment wheel that is easier to apply force can be directly set on the circumference of the screwing portion 411. The first snap ring 413 can be adapted to the second snap ring to achieve relative engagement between the adjustment connection portion 412 and the limiting groove 140, reducing the possibility of the adjustment body 410 falling off. After the first snap ring 413 and the second snap ring are engaged with each other, the relative rotation between the adjustment connection portion 412 and the limiting groove 140 is not affected. A damping member can be provided on the outer circumference of the adjustment connection portion 412 as needed to maintain the adjusted position through the damping member.

[0066] Reference Figure 4 In some embodiments of the present application, the pawl 320 includes a rotating connection portion 321, an engaging portion 322 and a stop block 323. The rotating connection portion 321 is rotatably connected to the fixed rod 330; the engaging portion 322 is arranged on one side of the rotating connection portion 321, can engage with the ratchet teeth on the ratchet 310, and can unidirectionally cut off the rotation of the ratchet 310; the stop block 323 is arranged on the side of the rotating connection portion 321 away from the engaging portion 322, and can limit the reverse rotation of the pawl 320.

[0067] Based on the above-described embodiment of the present application, the rotational connection portion 321 is the main portion that rotationally connects the pawl 320 to the fixed rod 330. The engagement portion 322 is disposed on the side of the rotational connection portion 321 that is adjacent to the ratchet 310. The engagement of the engagement portion 322 with the ratchet 310 enables the reverse blocking feature of the ratchet-pawl mechanism. The provision of the stopper 323 can limit the reverse rotation of the pawl 320, improving or even preventing the situation in which the pawl 320 cannot easily return to its original position due to excessive reverse rotation.

[0068] In some embodiments of the present application, the ratchet 310 and the winding assembly 200 are engaged with each other;

[0069] The inner side of the ratchet 310 is provided with a clamping member 311, and the winding assembly 200 is provided with a clamping groove 211 adapted to the clamping member 311. Figure 3 ;

[0070] Alternatively, a clamping groove 211 is provided on the inner side of the ratchet 310 , and a clamping piece 311 adapted to the clamping groove 211 is provided on the winding assembly 200 .

[0071] Based on the above-mentioned embodiments of the present application, the ratchet 310 can be mutually engaged with the winding assembly 200, and the specific engaging method can be set as needed. The ratchet 310 is specifically engaged at the end position of the support shaft 210 described below. The engagement of the ratchet 310 and the winding assembly 200 can be achieved through the cooperation of the engaging member 311 and the engaging groove 211. Specifically, the engaging member 311 can be set on the inner side of the ratchet 310, and the engaging groove 211 can be opened at a suitable position of the winding assembly 200, such as on the outer peripheral surface of the middle support shaft 210 described below; or the engaging groove 211 can be set on the inner side of the ratchet 310, and the engaging member 311 can be set at a suitable position of the winding assembly 200, such as on the outer peripheral surface of the middle support shaft 210 described below. The engaging member 311 and the engaging groove 211 appear in pairs, and the drawings of the present application are exemplified by taking four groups as an example.

[0072] It should be noted that, if necessary, the ratchet 310 and the winding assembly 200 can be connected by a fixing member or directly welded together. Alternatively, the above-mentioned snap connection plus a magnetic attraction structure can be used to improve the connection stability and reduce the possibility of accidental falling off of the ratchet 310 during assembly.

[0073] It should be noted that the ratchet 310 is an annular structure, or the ratchet 310 is a cover-like structure with an assembly groove. When the ratchet 310 is an annular structure, the inner side of the ratchet 310 refers to the inner wall of the annular structure; when the ratchet 310 is a cover-like structure with an assembly groove, the inner side of the ratchet 310 refers to the annular inner wall of the status groove.

[0074] In some embodiments of the present application, the winding assembly 200 includes a support shaft 210, a support frame 220 and a cable reel 230, the support shaft 210 is rotatably connected to the support assembly 100, and the ratchet 310 is connected to the support shaft 210; the support frame 220 is fixedly connected to the outer circumference of the support shaft 210; the cable reel 230 is sleeved on the support frame 220, and the inner circumference of the cable reel 230 is fixedly connected to the support frame 220, and the cable reel 230 can rotate with the support shaft 210.

[0075] Based on the above-mentioned embodiment of the present application, the support shaft 210 is the main supporting body of the winding assembly 200, and the support frame 220 and the cable drum 230 are both mounted on the support shaft 210. The rotation of the winding assembly 200 can also be driven by the rotation of the support shaft 210, and the ratchet 310 can be mounted at the end position of the support shaft 210. The support frame 220 can mount the cable drum 230 on the support shaft 210. The cable drum 230 is sleeved on the outer peripheral side of the support shaft 210. There is a gap between the cable drum 230 and the support shaft 210 bracket, and the support frame 220 is set in the gap. The support frame 220 can improve the connection strength between the cable drum 230 and the support shaft 210, and the corresponding number and shape of support frames 220 can be set as needed.

[0076] It should be noted that the support frame 220 includes at least two support units, and at least two support units are arranged in an annular array on the outer peripheral surface of the support shaft 210. The drawings of this application are illustrated with four support unit rings as an example. Figure 2 and Figure 3 .

[0077] In some embodiments of the present application, the support assembly 100 includes a base 110 and two support plates 120, the two support plates 120 are arranged at intervals on the base 110, the two support plates 120 and the base 110 form a mounting groove 130, the winding assembly 200 is installed between the two support plates 120, and the adjustment assembly 400 is installed on one of the two support plates 120; each support plate 120 is provided with a mounting hole 121, and the support shaft 210 is rotatably connected to the mounting hole 121.

[0078] Based on the above-mentioned embodiments of the present application, the base 110 can enable the support assembly 100 to have a better supporting effect, the support plate 120 can support the winding assembly 200, the two support plates 120 can form an installation groove 130 with the base 110, and the winding assembly 200 is installed in the installation groove 130. Both support plates 120 are provided with installation holes 121 that are compatible with the winding assembly 200, and the support shaft 210 can be rotatably connected to the installation hole 121. The mounting hole 121 on at least one support plate 120 is a through hole, and a limiting groove 140 connected to the mounting hole 121 is provided on the side of the support plate 120 facing away from the winding assembly 200. The ratchet 310 ratchet mechanism is arranged in the limiting groove 140, and the adjustment body 410 of the adjustment assembly 400 is rotatably connected to the limiting groove 140. The adjustment rod 420 can be driven to move by rotating the adjustment body 410. Since the adjustment rod 420 extends into the adjustment groove 324 of the pawl 320, the pawl 320 can be driven to move by the adjustment rod 420. After the pawl 320 moves to the point where it cannot engage with the ratchet 310, the ratchet mechanism of the ratchet 310 can be switched from a locked state to an unlocked state, so that the cable drum can be rotated to retract the cable, thereby increasing the flexibility and practicality of the device and improving the work efficiency of the staff.

[0079] It should be noted that the ratchet pawl mechanism in the present application can be set to the normal rotation direction of the cable outward direction and the cut-off direction of the cable retraction direction. This can solve the problem that most cables used for power surveys are wound on a bracket for transportation. When in use, the cable on the winding assembly is directly pulled out for use. When pulling the cable, since the winding assembly is in a rotating state, the above-mentioned ratchet pawl mechanism is unlikely to cause the bracket to rotate in the opposite direction and bring the cable back to its original position. This can reduce the physical exertion of the staff, improve the work efficiency of the staff, and is unlikely to knock down the staff holding the cable, so that the personal safety of the staff can be better protected.

[0080] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0081] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not intended to limit the scope of protection of the embodiments of the present application. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the scope of protection of the embodiments of the present application.
