Description

Technical Field

[0001] The utility model relates to the field of water conservancy project detection, in particular to a detection instrument for water conservancy project supervision. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. In water conservancy projects, a detector based on water conservancy project supervision is needed.

[0003] After searching the patent document with the announcement number CN217179638U, the patent document discloses "a detector for water conservancy project supervision, which is used in coordination with a positioning block, a limit block, a through hole, a positioning shell, a clamping block, a pull rod and a third spring. When the user needs to open the box cover, the user pulls the pull rod forward, and the pull rod drives the clamping block to squeeze the third spring, and then the clamping block is separated from the through hole, and the user can open the box cover at this time";

[0004] The above device only needs to pull the pull rod outward to open the box cover, so that the box cover can be opened without restriction. Such a locking structure is relatively simple. During the process of transferring the device to the processing area, if the round handle at the front end of the pull rod is caught, it is easy to cause the box cover to be opened, which may easily cause the detector body in the box to fall out and be damaged. Utility Model Content

[0005] The purpose of the utility model is to provide a detection instrument for water conservancy project supervision in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A detection instrument for water conservancy project supervision, comprising a box body, a top cover rotatably connected to the upper end of the box body, a detection mechanism installed inside the box body, and a locking mechanism for locking and fixing the top cover;

[0008] The locking mechanism includes a lower extension plate, which is fixed at the lower end of the front side of the top cover. A U-shaped frame is arranged on the periphery of the lower extension plate, and the U-shaped frame is fixed to the box body. Two return springs are fixed inside the lower extension plate, a slider is fixed at one end of the return spring, and the slider is slidably connected to the lower extension plate, a clamping block is fixed at one end of the slider, a groove is provided at the lower end of the lower extension plate, two fixed plates are fixed inside the groove, a bidirectional screw is rotatably connected in the middle of the fixed plate, two L-shaped frames are threadedly connected to the periphery of the bidirectional screw, and the L-shaped frame is slidably connected to the inner wall of the groove, and holes are provided on the inner walls at both ends of the U-shaped frame corresponding to the clamping blocks and the L-shaped frame.

[0009] Preferably: a front convex plate is provided at the front end of the sliding block.

[0010] Preferably, the outer ring of the middle section of the bidirectional screw is provided with a plurality of long square grooves with rounded corners.

[0011] Preferably, circular plates with a diameter larger than that of the bidirectional screw are provided at both ends of the bidirectional screw.

[0012] Preferably: the detection mechanism includes two spring dampers, the spring dampers are installed at the bottom of the box, a bearing frame is fixed on the upper end of the spring damper, and the bearing frame is slidably connected to the inner wall of the box, a loading frame is fixed inside the loading frame, and the detector body is installed on the upper end of the loading frame.

[0013] Preferably, the loading frame is made of lightweight plastic material.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] The two L-shaped frames can then be moved in opposite directions by rotating the two bidirectional screws, thereby causing one end of the two L-shaped frames to be inserted into the holes opened by the U-shaped frames corresponding to the holes opened by the L-shaped frames. The elasticity of the reset spring can then drive the card block to be inserted into the holes opened by the card block of the U-shaped frame, thereby causing the lower extension plate and the U-shaped frame to have a double locking engagement. This can reduce the possibility of the top cover being opened due to the locking structure being hung. When the device is transferred to the detection area and the top cover needs to be opened frequently, the bidirectional screw can be rotated in the opposite direction to reset the two L-shaped frames, thereby leaving only one locking force for opening the top cover, which is more convenient for opening the top cover.

[0030] The detection mechanism includes two spring dampers 3, which are installed at the bottom of the box body 1. A supporting frame 31 is fixed to the upper end of the spring damper 3, and the supporting frame 31 is slidably connected to the inner wall of the box body 1. A loading frame 32 is fixed inside the supporting frame 31. The loading frame 32 is made of a lightweight plastic material, and a detector body 33 is installed on the upper end of the loading frame 32. Through the arrangement of the two spring dampers 3, if the device encounters a certain amount of bumps during the transfer to the detection area, the two spring dampers 3 plus the cotton pad 22 can provide good protection for the detector body 33.

[0031] The locking mechanism includes a lower extension plate 4, which is fixed to the lower end of the front side of the top cover 2, a U-shaped frame 41 is arranged on the periphery of the lower extension plate 4, and the U-shaped frame 41 is fixed to the box body 1, two return springs 42 are fixed inside the lower extension plate 4, one end of the return spring 42 is fixed with a slider 43, the front end of the slider 43 is provided with a front convex plate, and the slider 43 is slidably connected with the lower extension plate 4, and a clamping block 44 is fixed at one end of the slider 43, a groove 45 is provided at the lower end of the lower extension plate 4, two fixing plates 46 are fixed inside the groove 45, a bidirectional screw 47 is rotatably connected in the middle of the fixing plate 46, a plurality of long square grooves with rounded corners are provided on the outer ring of the middle section of the bidirectional screw 47, circular plates with a larger diameter than the bidirectional screw 47 are arranged at both ends of the bidirectional screw 47, two L-shaped frames 48 are threadedly connected to the periphery of the bidirectional screw 47, and the L-shaped frames 48 are slidably connected to the inner wall of the groove 45, the inner walls at both ends of the U-shaped frame 41 correspond to the clamping blocks 44 and the L-shaped The two L-shaped frames 48 are all provided with holes; when the device needs to be transferred to the detection area, the bidirectional screw 47 is first rotated, and the two L-shaped frames 48 are threadedly connected through the bidirectional screw 47 and the two L-shaped frames 48 and the sliding connection between the L-shaped frames 48 and the inner wall of the groove 45. When the bidirectional screw 47 is rotated, the two L-shaped frames 48 can be moved in opposite directions, so that one end of the two L-shaped frames 48 is inserted into the hole opened in the L-shaped frame 48 corresponding to the U-shaped frame 41, and then the elasticity of the upper reset spring 42 can drive the card block 44 to be inserted into the hole opened in the card block 44 corresponding to the U-shaped frame 41, so that the lower extension plate 4 and the U-shaped frame 41 have a double locking card.

Through the threaded connection between the bidirectional screw 47 and the two L-shaped frames 48 and the sliding connection between the L-shaped frames 48 and the inner wall of the groove 45, when the bidirectional screw 47 is rotated, the two L-shaped frames 48 can be moved in opposite directions, so that one end of the two L-shaped frames 48 is inserted into the hole of the U-shaped frame 41 corresponding to the L-shaped frame 48, and then the elasticity of the reset spring 42 can drive the block 44 to be inserted into the hole of the U-shaped frame 41 corresponding to the block 44, so that the lower extension plate 4 has a double locking card with the U-shaped frame 41, which can reduce the situation that the top cover 2 is opened due to the locking structure being hung. When the device is transferred to the detection area and the top cover 2 needs to be opened frequently, the bidirectional screw 47 can be rotated in the opposite direction to make the two L-shaped frames 48 move in the opposite direction, so that the L-shaped frames 48 are separated from the U-shaped frame 41. When the top cover 2 needs to be opened and closed frequently, it is only necessary to push the two sliders 43 to make the card block 44 separate from the U-shaped frame 41, so that the top cover 2 can be opened, and then the detector body 33 can be used for detection processing.
