[0002] Cable trenches are underground channels for laying power cables and are used in various power plant projects. The quality of cable trench backfilling is directly related to the safe operation of cables and the stability of the entire power system. With the continuous expansion of the scale of outdoor photovoltaic power station construction and the continuous progress of technology, the construction of cable trenches is also increasing, and the demand for backfilling and compaction equipment is also growing. Compaction equipment is a type of engineering machinery that uses mechanical or hydraulic power to impact or vibrate and compact soil, foundations, etc., to improve density and load-bearing capacity.

[0003] The existing technology has the following problems:

[0004] In current cable trench backfilling compaction equipment, the tamping plate and frame are fixed together by several bolts. When replacing them, tools are needed to remove each bolt, making the removal of the tamping plate troublesome and laborious. In addition, the high-speed hydraulic cylinder inside the frame may get hot during long-term operation, and there is no heat dissipation structure, which affects the service life of the high-speed hydraulic cylinder.

[0005] Therefore, we need a compaction device for cable trench backfilling to solve the above problems. Utility Model Content

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figures 1 to 6As shown, this utility model provides a compaction device for backfilling cable trenches, including a frame 1. A high-speed hydraulic cylinder 9 is fixedly connected to the top of the inner wall of the frame 1. A tamping hammer 10 is fixedly connected to the output end of the high-speed hydraulic cylinder 9. The tamping hammer 10 is driven by the start of the high-speed hydraulic cylinder 9 to impact the force block 8. A frame-shaped mounting plate 2 is fixedly connected to the lower surface of the outer surface of the frame 1. A fixing plate 3 is provided on the lower surface of the frame-shaped mounting plate 2. A fixing column 4 is fixedly connected to the lower surface of the fixing plate 3. A tamping plate 5 is fixedly connected to the lower end of the fixing column 4. Through the cooperation of this structure, the compaction effect of the tamping hammer 10 on the soil is facilitated. A mounting plate 7 is fixedly connected to the lower rear side of the frame 1. The mounting plate 7 is easy to install on the hydraulic system of the modified loader and is installed in the position after the loader bucket is removed, so as to use the original hydraulic power for operation. In addition, the loader, the high-speed hydraulic cylinder 9 and the tamping hammer 10 are all existing technologies and will not be described in detail here.

[0029] The upper surface of the frame mounting plate 2 is provided with connecting components 6 on the front, back, left and right sides. The two connecting components 6 on the front and back are mirrored, and the two connecting components 6 on the left and right sides are mirrored. The mirrored arrangement facilitates the disassembly of the connecting components 6 after installation. The upper surface of the fixing plate 3 is fixedly connected with a force-bearing block 8, and the outer surface of the force-bearing block 8 corresponds to the outer surface of the hammer 10.

[0030] Example 2: Figures 1 to 6As shown, the connecting component 6 includes an insert block 61. A limiting groove 62 is formed on the upper front of the insert block 61, and a blocking block 65 is correspondingly provided inside the limiting groove 62. Through the cooperation of this structure, it facilitates initial limiting and fixing. Furthermore, the two are in contact. The lower left surface of the blocking block 65 is movably connected to the upper surface of the frame-shaped mounting plate 2. This movable connection allows the blocking block 65 to rotate and separate from the insert block 61, achieving an open state; conversely, it is in a limited state. The outer surface of the insert block 61 penetrates the interior of the frame-shaped mounting plate 2 for insertion. The lower end of the insert block 61 is fixedly connected to the upper surface of the fixing plate 3. When the blocking block 65 rotates open, it facilitates the disassembly of the fixing plate 3. An L-shaped groove 63 is formed on the right side of the front of the insert block 61, facilitating the entry of an L-shaped block 68. A positioning hole 64 is formed in the middle left side of the inner wall of the L-shaped groove 63, facilitating positioning. The insertion of the post 69 limits the blocking block 65, preventing it from rotating. A groove 66 is provided on the right side of the upper surface of the blocking block 65. A lead screw 67 is installed inside the groove 66, with its outer surface threaded through the groove. An L-shaped block 68 is threaded through the outer surface of the lead screw 67. A positioning post 69 is fixedly connected to the left side of the L-shaped block 68 in the vertical direction. The outer surface of the positioning post 69 corresponds to the inside of the positioning hole 64. Through this coordinated structure, when the operator rotates the lead screw 67, the L-shaped block 68 slides within the groove 66, allowing it to move left and right within the groove. When the L-shaped block 68 moves to the left, the positioning post 69 inserts into the positioning hole 64; conversely, when the L-shaped block 68 moves to the right, the positioning post 69 separates from the positioning hole 64, facilitating the opening of the blocking block 65. The outer surface of the positioning post 69 engages with the inside of the positioning hole 64.

[0031] In addition, a semi-circular block is fixed on the upper surface of the blocking block 65 near the slide groove 66. The semi-circular block is designed to ensure that the limiting groove 62 is in a tight state when the blocking block 65 is closed. The semi-circular block is made of rubber, which gives the insert 61 a certain upward pulling force, resulting in a tight fit between the frame mounting plate 2 and the fixing plate 3.

[0032] Example 3: Figures 1 to 6As shown, a heat dissipation assembly 11 is installed on the outer surface of the high-speed hydraulic cylinder 9. The heat dissipation assembly 11 includes a heat-conducting sleeve 111. The heat-conducting sleeve 111 facilitates the heat conduction of the surface heat of the high-speed hydraulic cylinder 9. Heat dissipation vents 112 are provided on both the front and rear sides of the outer surface of the heat-conducting sleeve 111, allowing the surface heat of the high-speed hydraulic cylinder 9 to be directly dissipated. Heat dissipation plates 113 are fixedly connected to both the left and right sides of the outer surface of the heat-conducting sleeve 111. The design of the heat dissipation plates 113 facilitates the dissipation of the conducted heat, and the heat dissipation plates 113 increase the heat dissipation area, thus improving heat dissipation on both sides. Air guide slots 114 are provided on both the front and rear sides of the heat sink 113. The fan 115 facilitates the blowing of air and can remove the heat in the air guide slots 114, thus accelerating the heat loss from the surface of the heat sink 113. Fans 115 are fixedly connected to the upper surface of the left and right heat sinks 113. The fan 115 is composed of a rectangular shell, a motor, fan blades, and a support rod. The heat conduction sleeve 111 and the heat sink 113 are made of copper. In addition, the heat sink 113 is designed to divide the air blown out by the fan 115 into two parts, corresponding to the front and rear positions respectively, which facilitates the heat dissipation speed of the heat sink 113.

[0033] The rectangular housing of the fan 115 is fixedly connected to the surface of the heat sink 113, and an installation port is provided in the middle of the rectangular housing. The fan blade is installed inside the installation port. The output shaft of the motor is fixedly installed to the middle of the fan blade. Two support rods are provided inside the installation port. The two end faces of the support rods are fixed to the motor and the inner wall of the installation port, respectively. In addition, the motor is electrically connected to the battery in the loader.

[0034] Working principle: In use, the operator first rotates the lead screw 67, which moves the L-shaped block 68, causing the positioning post 69 to separate from the inside of the positioning hole 64. Then, the blocking block 65 is rotated to separate the blocking block 65 from the position of the insert block 61. Then, the fixing plate 3 is moved downward to facilitate the disassembly and replacement of the structure in the fixing plate 3. When the high-speed oil cylinder 9 works for a long time, the heat conduction sleeve 111 facilitates heat conduction, and the heat is dissipated through the heat dissipation plate 113. Due to the heat dissipation port 112, the heat of the high-speed oil cylinder 9 itself is directly dissipated, and the surface heat dissipation speed of the heat dissipation plate 113 is accelerated by the action of the fan 115.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
