The speed sensor is installed on the speed sensing wheel and is electrically connected to the control module. The wire pressing guide wheel is opposite to the speed sensing wheel. The cable passes through the shell and passes through the junction of the speed sensing wheel and the wire pressing guide wheel. A cable protection ring is installed in the cable hole of the shell.

[0003] However, the following situations may occur during the use of the controller: in rainy weather or in puddles in the middle of the road, water droplets may stick to the cable, and the cable protection ring on the shell cannot scrape the water droplets off the cable, causing the water droplets to enter the shell along the cable. Once the water droplets adhere to the components in the shell, it is easy to cause component failure. Summary of the invention

[0004] The utility model aims to provide a middle control box of an intelligent cable puller to solve the technical problem that water drops on the cable may enter into the shell during operation, causing failure of components.

[0007] The interior of the upper cover is provided with a third semicircular groove and a fourth semicircular groove adapted to the first semicircular groove and the second semicircular groove; the first semicircular groove and the third semicircular groove constitute a cable feeding circular groove; the second semicircular groove and the fourth semicircular groove constitute a cable discharging circular groove;

[0008] The first semicircular groove and the third semicircular groove are respectively provided with wiper blocks in the grooves close to the outer side surfaces. The wiper blocks are semicircular arc blocks and are arranged relatively to each other. Among them, the outer side surface of the wiper block in the first semicircular groove is provided with a water guide groove, and the opening of the water guide groove faces outward to facilitate the discharge of water droplets.

[0009] Furthermore, the inner surfaces of the first semicircular groove and the third semicircular groove are evenly provided with arrays of relatively arranged wiper blocks; the inner surfaces of the second semicircular groove and the fourth semicircular groove are evenly provided with arrays of relatively arranged wiper blocks.

[0010] Furthermore, a diamond-shaped frame is provided at the center of the bottom of the lower shell, and two cushion blocks are respectively provided on both sides of the diamond-shaped frame; the cushion blocks are consistent in height with the diamond-shaped frame.

[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0028] Please refer to Figure 1-Figure 6 As shown, the technical solution adopted by the utility model is: an intermediate control box of an intelligent cable puller, comprising an upper cover 1 and a lower shell 2; a partition 3 is arranged between the upper cover 1 and the lower shell 2, and a receiving cavity for placing a power supply, a control module and various components is formed between the partition 3 and the lower shell 2, and a wire guide 10 is located between the partition 3 and the upper cover 1;

[0029] A downwardly concave groove 31 for placing the wire guide is provided at the center of the partition 3; a first semicircular groove 4 and a second semicircular groove 5 are provided on both sides of the upper surface of the groove 31 along the length direction, and both extend to the outermost side;

[0030] The interior of the upper cover 1 is provided with a third semicircular groove 6 and a fourth semicircular groove 7 which are matched with the first semicircular groove 4 and the second semicircular groove 5; the first semicircular groove 4 and the third semicircular groove 6 constitute a cable feeding circular groove; the second semicircular groove 5 and the fourth semicircular groove 7 constitute a cable discharging circular groove;

[0031] The first semicircular groove 4 and the third semicircular groove 6 are respectively provided with wiper blocks 8 in the grooves close to the outer sides. The wiper blocks 8 are semicircular arc blocks and are arranged relatively. Among them, the outer side of the wiper block 8 in the first semicircular groove 4 is provided with a water guide groove 9, and the opening of the water guide groove 9 faces outward to facilitate the discharge of water droplets.

[0032] From the above description, it can be known that by arranging two wiper blocks 8 in the first semicircular groove 4 and the third semicircular groove 6, the water droplets carried on the cable can be scraped off, and the fallen water droplets are discharged to the outside of the box along the water guide groove 9, effectively preventing the water droplets from entering the box along with the transmission of the cable, thereby solving the problem of component failure caused by water droplets entering the box. In addition, the partition 3 can further isolate the influence of water droplets on the components to ensure the use effect of the components.

[0033] More preferably, the inner surfaces of the first semicircular groove 4 and the third semicircular groove 6 are evenly provided with arrays of relatively arranged wiper blocks 8; the inner surfaces of the second semicircular groove 5 and the fourth semicircular groove 7 are evenly provided with arrays of relatively arranged wiper blocks 8.

[0034] From the above description, it can be known that by setting a plurality of wiper blocks 8, the contact area between the cable and the inner surface of the first semicircular groove 4, the second semicircular groove 5, the third semicircular groove 6 and the fourth semicircular groove 7 during the transmission process can be reduced, thereby reducing the friction force and reducing the wear of the semicircular grooves themselves on the cable surface. At the same time, it can also play a role in scraping off water droplets on the cable. If a very small amount of water droplets enter the box body through the outermost wiper block 8, the water droplets can also be scraped into the cable feeding circular groove under the action of other wiper blocks 8, and will not enter the components.

[0035] More preferably, a diamond-shaped frame 21 is provided at the center of the bottom of the lower shell 2 , and two cushion blocks 22 are respectively provided on both sides of the diamond-shaped frame 21 ; the cushion blocks 22 are consistent in height with the diamond-shaped frame 21 .

[0036] From the above description, it can be seen that through the above settings, the strength of the corresponding position of the bottom of the lower shell 2 can be improved; since heavier devices such as power supplies are installed inside the lower shell 2, after improving the strength of the corresponding position, it is possible to effectively prevent the lower shell 2 from cracking and increase its service life.

[0037] More preferably, the diamond frame 21 has a thickness of 3-5 mm, and a plurality of anti-slip grooves are evenly arranged on its surface.

[0038] It can be seen from the above description that, through the above settings, it is ensured that the diamond frame 21 itself has sufficient strength, and at the same time, when in contact with the working surface, it has sufficient anti-slip function to ensure the stability of the controller during operation.

[0039] More preferably, ventilation holes 23 are evenly provided on two side surfaces in the length direction of the lower shell 2 .

[0040] It can be seen from the above description that the above arrangement is conducive to discharging the heat generated by the components in the lower shell 2 from the inside of the shell to the outside, thereby reducing the temperature inside the shell.

[0041] More preferably, the upper and lower end surfaces of the ventilation hole 23 are inclined to the end surface of the lower shell 2 .

[0042] It can be seen from the above description that, through the above arrangement, the upper and lower end surfaces of the ventilation hole 23 are arranged to be inclined, which can prevent water droplets from entering the interior of the shell through the ventilation hole 23 while ensuring the ventilation effect.

[0043] The working principle of the utility model is as follows: before operation, the control box is placed on a suitable working surface, and the diamond frame 21 and the cushion block 22 at the bottom of the lower shell 2 are used to contact the working surface, which has good stability; the upper cover 1 is opened, and the cable is placed from the wiper block 8 along the first semicircular groove 4 to the outlet of the second semicircular groove 5, and at the same time, the cable passes through the surface of the wire guide 10 located in the middle position; then the upper cover 1 is installed back to its original position, at this time, the two ends of the cable are respectively located in the cable feeding circular groove and the cable discharging circular groove.

[0044] When the wire guide 10 is started, the cable starts to move. During the movement, the surface of the wiper block 8 contacts the surface of the cable, scraping water droplets attached to the surface of the cable into the water guide groove 9, and then discharged out of the box body along the water guide groove 9.

[0045] During the transportation of the cable, if a small amount of water droplets are not scraped off by the wiper block 8 and enter the box body, the water droplets can also be scraped off into the cable feeding circular groove under the action of other wiper blocks 8 to ensure that the water droplets will not enter the components.

[0046] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
