[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 3 As shown in the figure, a specific embodiment of the present invention discloses an auxiliary device for aiming at a hydrological speed gun monitoring point, including a first kit 100 and a second kit 200; the end face of the first kit 100 is equipped with a plurality of laser lights 310 and lighting lights 320, which are distributed in a circular array around the same center and are staggered; a battery 330 is installed inside the first kit 100 to power the laser lights 310 and lighting lights 320; the second kit is plugged into and connected to the first kit, forming a clamping part between the two.

[0029] The above-mentioned auxiliary device for aiming at a monitoring point of a hydrological speed gun has a second component that is plugged into and connected to the first component, forming a clamping part between them. It can be used as an add-on structure and is compatible with various radar speed guns, thus improving its applicability.

[0030] Among them, it can provide auxiliary lighting through the lighting lamp and provide long-distance illumination guidance through the laser lamp, which can serve as an aiming indicator to determine the detection location;

[0031] Furthermore, the laser lights and illumination lights are arranged in a circular array around the same center and at staggered intervals. This not only makes the light distribution more uniform, but also ensures that both are centered on the speed gun probe. Especially when both are turned on at the same time, the diffused light of the illumination lights provides a wide range of illumination, while the focused beam of the laser lights accurately falls on the detection point.

[0032] Furthermore, such as Figure 3 As shown, the first kit 100 has at least two insertion holes 110 on its end face near the second kit, and multiple slots 120 evenly spaced along the length direction are provided on the wall surface of the insertion holes 110 away from the center of the first kit. The slots penetrate the outer wall of the first kit.

[0033] The second kit 200 has a fixed insert rod 210 on its wall near the first kit. A clip 220 is fixed on the outer wall of the end of the insert rod 210. The shape of the clip 220 matches the shape of the slot 120. The second kit is connected to the first kit through the insert rod and the clip to form a snap-fit ​​connection with the insertion hole and slot of the first kit. The first kit and the second kit are engaged and can be easily adjusted and used. When installation is required, first put the first kit on the head of the speed gun, then put the second kit on the rear end of the speed gun, and then insert the insert rod into the insertion hole and move it until the clip is locked in the corresponding slot to form a locking effect, thus completing the installation. The operation is simple. In addition, the multiple slots arranged in a row can be adapted to speed guns of different lengths, so that they can all achieve the effect of locking and installing.

[0034] Furthermore, the first assembly 100 includes a first collar 130, with a support block 140 fixedly mounted at the rear end of the first collar 130. The support block has an arc-shaped ring structure with a notch in its cross-section. There are two insertion holes 110, distributed on opposite sides of the support block 140. A clamping cavity 150 is provided inside the first collar 130 and the support block 140 for installing the battery 330 and the circuit board 340. The circuit board 340 integrates a charging module 350 and a control button 360. Corresponding... The first through hole is where the control button's press head and the charging module's interface extend. The end of the clamping cavity 150 away from the through hole is open, and a cover ring 160 is installed at the open end. The cover ring 160 has multiple second through holes 161 for installing laser lights and illumination lights. The battery, laser lights, and illumination lights are all electrically connected to the circuit board. This allows it to be used as an independent modular device, which can be directly and conveniently installed on the speed gun to provide the required power supply and lighting. It does not require electrical connection with the speed gun; only structural fit is needed, making it convenient to use.

[0035] The cover ring has a retaining ring fixed at one end of its inner wall. The outer diameter of the retaining ring is adapted to the inner diameter of the outer ring of the clamping cavity. The cover ring is installed at the port of the clamping cavity by the retaining ring. A threaded ring seat is fixed on the outer side of the inner end of the second through hole for installing lighting lamps and laser lamps. Alternatively, the lighting lamps and laser lamps can be integrated into the photovoltaic panel, and then the photovoltaic panel can be installed on the cover ring with screws and connected to the power supply to achieve the corresponding adjustment and control. The whole structure is a detachable structure, which can facilitate the processing and production of each structural component and facilitate production assembly.

[0036] Furthermore, the support block has cutting surfaces on opposite sides, and the two cutting surfaces are parallel to each other; the bayonet is located on the cutting surface; the external sliding latch of the support block 140 is equipped with an unlocking component 400, which can be adjusted to push the latch head away from the bayonet to achieve unlocking; the cutting surface setting makes the wall thickness of the bayonet part uniform, which facilitates the latch head to be engaged and installed, and also facilitates the unlocking component to cooperate with it to achieve the unlocking action.

[0037] Furthermore, such as Figure 4 As shown, the unlocking component 400 includes a sleeve 410, the shape of which is adapted to the cross-sectional shape of the support block 140, and the sleeve is slidably engaged with the outer wall of the support block; the sleeve 410 has a third through hole 420 on opposite sides, the position of which corresponds to the position of the latch 120; the width of the third through hole is adapted to the width of the latch, and the length of the third through hole is greater than the length of the latch; a pressure plate 430 is provided on the outer side of the third through hole 420, the top of the pressure plate 430 extends upward and is connected to the outer wall of the sleeve 410, and a pressure block 440 is fixedly provided on the wall surface of the pressure plate 430 near the third through hole, the shape of which is adapted to the shape of the latch 120; when force is applied to the pressure plate, the pressure block can extend into the corresponding latch to push the card head away from the fastening part; the overall structure is simple and easy to use.

[0038] Among them, since the cross-section of the support block is an arc-shaped ring structure with a notch, the bottom of the sleeve is provided with a corresponding bend, which limits the sleeve to slide only along the outer wall of the support block and will not easily detach or fall off the support block.

[0039] Furthermore, the outer wall of the support block is provided with multiple sets of positioning grooves corresponding to the bayonet, and the inner wall of the sleeve is provided with multiple locking points. The locking points and positioning grooves work together to prevent the unlocking parts from sliding randomly, and can also adjust the alignment, making it easy to move the unlocking parts to the part that needs to be unlocked for accurate alignment.

[0040] Furthermore, the inner diameter of the first ring 130 gradually increases towards the support block 140; the second assembly 200 includes a second ring 230, and the insertion rod 210 is fixedly disposed on both sides of the end face of the second ring 230 near the first assembly 130; the inner diameter of the second ring 230 gradually increases towards the insertion rod 210; this structural design allows for the adaptation of speed measuring guns of different diameters through the variable diameter parts of the first and second rings, so that they can be engaged at both ends of the speed measuring gun body, which can further improve applicability.

[0041] Furthermore, a soft rubber ring 240 is fixedly provided on the inner wall of the second ring 230. The inner diameter of the soft rubber ring 240 gradually increases towards the insertion rod 210. The soft rubber ring provides deformable space to accommodate speed guns of different lengths, and also ensures that the clamp head and the clamp can effectively engage, thereby enabling the first and second kits to effectively engage and tighten. In addition, the soft rubber ring can also provide sufficient friction to prevent the illumination auxiliary device from rotating easily. Of course, it should be noted that since the lighting lamp and laser lamp are both centered on the probe, even if there is a rotational shift, it will not affect the normal lighting and indication functions.

[0042] like Figure 5 , Figure 6As shown, in practical applications, the illumination aid is installed on the radar speed gun body; it should be noted that radar speed guns are relatively common speed measuring instruments and can be purchased and used on the market, so details will not be elaborated.

[0043] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
